(2)

Estimated solely for purposes of calculating the registration fee and computed pursuant to Rules 457(f) and (o) promulgated under the Securities Act, based on $37.27, the average of the high and the low prices of common stock of Constellation Energy Group, Inc. as reported on the New York Stock Exchange on June 22, 2006 ($53.82) adjusted to take into account the proposed stock split of the shares of common stock of Constellation Energy Group, Inc. to be effective immediately prior to the merger, and multiplied by the maximum number of shares of common stock of Constellation Energy Group, Inc. to be issued pursuant to the merger.

(3)	Calculated in accordance with Section 6(b) of the Securities Act and Rule 457(f)(1) promulgated thereunder.

(4)	The full registration fee of $1,612,083 was paid in connection with the initial filing on June 23, 2006.

The registrant hereby amends this registration statement on such date or dates as may be necessary to delay its effective date until the registrant shall file a further amendment which specifically states that this registration statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act or until the registration statement shall become effective on such date as the Commission, pursuant to said Section 8(a), may determine.

Preliminary Copy—Subject to Completion, dated August 28, 2006

Dear Constellation stockholders and FPL Group shareholders:

On behalf of the boards of directors and management teams of both Constellation Energy Group, Inc., which we refer to as Constellation, and FPL Group, Inc., which we refer to as FPL Group, we are pleased to deliver our joint proxy statement/prospectus for the merger of our two companies. We will use the term “combined company” to refer to Constellation as it will exist after completion of the merger.

Immediately prior to the merger, Constellation will effect a 1.444-to-1 stock split of the shares of Constellation common stock. After giving effect to the stock split, upon completion of the merger, FPL Group shareholders will receive one share of Constellation common stock for each share of FPL Group common stock that they held immediately prior to the merger. Upon completion of the merger and the related Constellation stock split, Constellation stockholders prior to the merger will own approximately 40% of the combined company’s outstanding shares of common stock and the FPL Group shareholders prior to the merger will own approximately 60% of the combined company’s outstanding shares of common stock. The shares of the combined company will be traded on the New York Stock Exchange under the symbol “CEG”. On [·], 2006, the most recent date prior to the mailing of this joint proxy statement/prospectus, the closing price of Constellation common stock on the New York Stock Exchange was $[·] (which does not reflect the effect of the 1.444-to-1 stock split to be effected immediately prior to the merger) and the closing price of FPL Group common stock on the New York Stock Exchange was $[·].

We are asking Constellation stockholders to approve (1) the issuance of shares of Constellation common stock to the former FPL Group shareholders in the merger and (2) an amendment and restatement of the Constellation charter to, among other things, increase the number of authorized shares of Constellation common stock (to facilitate both the stock split and the issuance of shares in the merger). The Constellation board of directors recommends that Constellation stockholders vote FOR the proposals related to the merger.

We are asking the FPL Group shareholders to approve the merger agreement. The FPL Group board of directors recommends that FPL Group shareholders vote FOR the proposal related to the merger.

The places, dates and times of the annual meetings are as follows:


For FPL Group shareholders:		For Constellation stockholders:

Before voting, you should carefully review all the information contained in the attached joint proxy statement/prospectus. For a discussion of risk factors which you should consider in evaluating the merger, see “ RISK FACTORS” beginning on page 22.

Whether or not you expect to attend the applicable annual meeting, the details of which are described on the following pages, please complete, date, sign and promptly return the accompanying proxy card in the enclosed envelope or submit your voting instructions by telephone or through the Internet if that option is available to you.

THE INTRODUCTION

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETINGS

Q:	Why am I receiving this document?

We are delivering this joint proxy statement/prospectus to you because you are either a Constellation stockholder, a FPL Group shareholder, or both. This document is serving as both a joint proxy statement of Constellation and FPL Group and a prospectus of Constellation. It is a joint proxy statement because it is being used by our boards of directors to solicit proxies from our stockholders. It is a prospectus because Constellation is offering shares of its common stock in exchange for shares of FPL Group common stock in connection with the proposed merger of the two companies (which we refer to herein as the merger).

Q:	What do I need to do now?

After you carefully read this joint proxy statement/prospectus, complete, sign and mail your proxy card in the enclosed return envelope, or submit your proxy by telephone or through the Internet, as soon as possible, so that your shares may be represented at your meeting. In order to assure that your vote is recorded, please submit your proxy as instructed on your proxy card even if you currently plan to attend your meeting in person.

Q:	Why have Constellation and FPL Group decided to merge?

A:	Constellation and FPL Group believe that the combination will provide substantial strategic and financial benefits to their stockholders and customers and the communities they serve, including:

•

diversification of business and increased scale;

•

financial strength and flexibility;

•

expanded capacity to generate electricity;

•

stronger competitive energy business platform;

•

enhanced nuclear expertise;

•

increased breadth of fuel mix and renewable portfolio, which will include the largest wind generation portfolio in the country;

•

improved and strengthened regulated businesses, with a broader platform for greater reliability and enhanced customer service; and

•

combined expertise and synergies.

Additional information on the reasons for the merger is located beginning on page 55 for Constellation and on page 79 for FPL Group.

Q:	When do you expect the merger to be completed?

We hope to complete the merger as soon as reasonably practicable. We are working to complete the merger by the end of 2006 or the first quarter of 2007. In August 2006, the Public Service Commission of the State of Maryland issued a procedural order indicating that it would be in a position to issue a ruling on the approval of the merger in February 2007. The companies will continue to try to expedite the approval process to complete the merger as soon as practicable. In addition, other factors outside of our control could require us to complete the merger at a later time or not to complete it at all. For a discussion of the conditions to the completion of the merger and of the risks associated with obtaining regulatory approvals in

connection with the merger, see “The Proposed Merger—The Merger Agreement—Conditions” beginning on page 141 and “Risks Factors — The merger is subject to receipt of consent or approval from governmental entities that could delay or prevent the completion of the merger or impose conditions that could have a material adverse effect on the combined company or that could cause abandonment of the merger” beginning on page 24.

Q:	If I am a Constellation stockholder, what will I receive as a result of the stock split and merger?

In connection with the completion of the merger, Constellation will effect a stock split of the shares of Constellation common stock outstanding immediately prior to the completion of the merger (which we refer to herein as the stock split). As a result of the stock split, Constellation stockholders will receive 1.444 shares of common stock of the combined company for every share of Constellation common stock they owned immediately prior to the stock split and the merger. We will not issue fractional shares but will pay cash in lieu of fractional shares resulting from the stock split.

Q:	If I am a FPL Group shareholder, what will I receive as a result of the merger?

A:	FPL Group shareholders will receive one share of common stock of the combined company (after the effectiveness of the stock split) in exchange for each share of FPL Group common stock they owned immediately prior to the merger.

Q:	Should I send in my stock certificates now?

A:	Constellation Stockholder:

No. After the stock split is completed, Constellation will send holders of Constellation common stock prior to the effectiveness of the stock split the additional shares of Constellation common stock received as a result of the stock split (and/or cash in lieu of fractional shares resulting from the stock split).

A:	FPL Group Shareholder:

No. After the merger is completed, Constellation will send FPL Group shareholders written instructions for exchanging their FPL Group stock certificates for certificates representing Constellation common stock.

Q:	On what am I being asked to vote?

A:	Constellation Stockholder:

You are being asked to consider and vote on the following matters:

A proposal to approve the issuance of shares of Constellation common stock to FPL Group shareholders (which we refer to herein as the share issuance proposal) as contemplated by the Agreement and Plan of Merger, dated as of December 18, 2005, among Constellation, CF Merger Corporation (which is a wholly owned subsidiary of Constellation) and FPL Group (which we refer to herein as the merger agreement). A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus.

A proposal to approve, effective as of the completion of the merger, the amended and restated charter of Constellation substantially in the form attached as Annex F to this joint proxy statement/prospectus, which we refer to as the charter amendment proposal, such proposal to include an individual proposal for approval of each specific amendment, as described in this joint proxy statement/prospectus under the section “The Proposed Merger—Post-Merger Corporate Governance and Management—Amended and Restated Constellation Charter and By-laws” beginning on page 145. Constellation stockholders may vote on each of the individual amendments contemplated by the amended and restated Constellation charter separately or on all of the amendments collectively.

The election of Class I directors to the Constellation board of directors to serve three year terms to expire in 2009.

A proposal to ratify the appointment of PricewaterhouseCoopers LLP as Constellation’s independent registered public accounting firm for the year 2006.

A stockholder proposal.

Any such other matters as may properly come before the annual meeting and any adjournment or postponement of the annual meeting.

A:	FPL Group Shareholder:

You are being asked to consider and vote on the following matters:

A proposal to approve the merger agreement.

Election of FPL Group’s directors.

Ratification of the appointment of Deloitte & Touche LLP as FPL Group’s independent registered public accounting firm for the year 2006.

Such other matters as may properly come before the annual meeting and any adjournment or postponement of the annual meeting.

Q:	What is the purpose of the amendment and restatement of the Constellation charter?

Constellation is proposing to amend and restate its charter to effect various terms of the merger as described in this joint proxy statement/prospectus. Constellation does not intend to amend and restate the Constellation charter unless the merger will be completed (even if the Constellation stockholders have approved the charter amendment proposal).

Q:	Are there risks I, as a Constellation stockholder or FPL Group shareholder, should consider in deciding how to vote on the proposals related to the merger?

Yes, in evaluating the proposals related to the merger, you should carefully read this joint proxy statement/prospectus, including the factors discussed in the section titled “Risk Factors” beginning on page 22. You are urged to read this joint proxy statement/prospectus in its entirety prior to voting or submitting a proxy.

Q:	Why is my vote important?

If you do not return your proxy card or submit your proxy by telephone or through the Internet or vote in person at your annual meeting, it will be more difficult for Constellation and FPL Group to obtain the necessary quorum to hold their respective annual meetings. For both the Constellation annual meeting and the FPL Group annual meeting, the presence, in person or by proxy, of holders of a majority of the issued and outstanding shares entitled to vote at the meeting constitutes a quorum for the transaction of business. If a quorum is not present at either Constellation’s annual meeting or FPL Group’s annual meeting, the stockholders of that company will not be able to take action on any of the proposals at that meeting. In addition, for the Constellation charter amendment proposal and the FPL Group proposal to approve the merger agreement, if you do not vote, it will have the same effect as a vote AGAINST the proposal, as described below. In addition, for the Constellation share issuance proposal, if you do not vote, it will be less likely that the minimum vote required for a vote on the proposal to be effective will be obtained. Therefore, if you do not vote, it will be more difficult for Constellation and FPL Group to obtain the stockholder approvals necessary for the completion of the merger, and it will be less likely that the merger will be completed.

Q:	May I vote in person?

Yes. If you are a stockholder of record as of [·], 2006 for Constellation or [·], 2006 for FPL Group, you may attend your annual meeting and vote your shares in person instead of returning your signed proxy card or submitting your proxy by telephone or through the Internet. However, because you can revoke a previously granted proxy by attending your annual meeting and voting your shares in person, we urge you to return your proxy card or submit your proxy by telephone or through the Internet even if you intend to attend your annual meeting.

Q:	If I am a record holder of my shares, what happens if I don’t submit a proxy (whether by returning my proxy card or submitting my proxy by telephone or through the Internet) or attend my annual meeting to vote in person?

A:	Constellation Stockholder:

If you do not return your proxy card or submit your proxy by telephone or through the Internet or vote in person at your annual meeting, your vote will not be counted and it will be less likely that a quorum to conduct business at your annual meeting will be obtained. In addition, if you are a Constellation stockholder, not returning your proxy card and not voting in person at the annual meeting will have the same effect as a vote AGAINST the approval of the Constellation charter amendment proposal because the approval of the proposal by a majority of the outstanding shares of Constellation common stock entitled to vote on the proposal is required to approve the charter amendment proposal. In addition, for the Constellation share issuance proposal, if you do not vote, it will be less likely that the minimum vote required for a vote on the proposal to be effective will be obtained.

A:	FPL Group Shareholder:

If you do not return your proxy card or submit your proxy by telephone or through the Internet or vote in person at your annual meeting, your vote will not be counted and it will be less likely that a quorum to conduct business at your annual meeting will be obtained. In addition, if you are a FPL Group shareholder, not returning your proxy card and not voting in person at the annual meeting will have the same effect as a vote AGAINST the approval of the proposal to approve the merger agreement because the approval of the proposal by a majority of the outstanding shares of FPL Group common stock entitled to vote on the proposal is required to approve the merger agreement.

Q:	If my shares are held in “street name” by my broker, will my broker vote my shares for me even if I don’t give my broker voting instructions?

Your broker will vote your shares if you provide instructions on how to vote. In addition, brokerage firms have the authority under the rules of the New York Stock Exchange, which we refer to herein as the NYSE, to vote their clients’ unvoted shares on certain routine matters. However, the proposals related to the merger and the Constellation stockholder proposal are not routine matters under the NYSE rules, and your broker does not have discretionary authority to vote on those proposals. Therefore, if your shares are held in “street name” by your broker and you do not provide your broker with instructions on how to vote your “street name” shares, if you are a Constellation stockholder, your broker will not be permitted to vote on the charter amendment proposal, the share issuance proposal or the Constellation stockholder proposal or, if you are a FPL Group shareholder, your broker will not be permitted to vote on the approval of the merger agreement.

You should therefore be sure to provide your broker with instructions on how to vote your shares. Please check the voting form used by your broker to see if it offers telephone or Internet submission of proxies.

Under the NYSE rules, brokers do have authority to vote their clients’ unvoted shares on certain routine matters, including those related to the election of directors and the ratification of appointment of an independent registered public accounting firm. If you do not provide voting instructions, your broker may choose to vote for you or leave your shares unvoted on such routine matters.

Q:	What does it mean if I receive more than one set of materials?

This means you own shares of Constellation common stock or FPL Group common stock that are registered under different names or in different forms, or you own shares in both companies. For example, you may own some shares directly as a stockholder of record and other shares through a broker or you may own shares through more than one broker. In these situations and others, you will receive multiple sets of proxy materials. It is necessary for you to vote, sign and return all of the proxy cards, or follow the instructions for any alternative voting procedure on each of the proxy cards you receive, in order to vote all of the shares you own. Each proxy card you receive will be accompanied by its own prepaid return envelope; if you submit your proxy by mail, make sure you return each proxy card in the return envelope which accompanied that proxy card.

Q.	How do I vote my FPL Group 401(k) shares?

If you participate in any of FPL Group, Inc.’s Employee Retirement Savings Plans (which we refer to herein as the FPL Group Retirement Savings Plans), you may give voting instructions to Fidelity Management Trust Company, as trustee of the FPL Group Retirement Savings Plans, by completing and returning the Retirement Savings Plans proxy card accompanying this joint proxy statement/prospectus. Your instructions will tell the trustee how to vote the number of shares of FPL Group common stock reflecting your proportionate interest in the FPL Group Stock Fund and the FPL Group Leveraged ESOP Fund. Your instructions will also determine the vote on a proportionate number of the Leveraged ESOP shares which are held in the FPL Group Retirement Savings Plans but not yet allocated to participants. If you do not give the trustee of the FPL Group Retirement Savings Plans voting instructions, the number of shares reflecting your proportionate interest will not be voted, but your proportionate share of the unallocated Leveraged ESOP shares will be voted by the trustee in the same proportions as it votes unallocated shares for which instructions are received. The trustee will vote your shares in accordance with your duly executed proxy card received by [·], 2006.

You may also revoke previously given voting instructions by [·], 2006, by filing with the trustee of the FPL Group Retirement Savings Plans either a written notice of revocation or a properly completed and signed Retirement Savings Plans proxy card bearing a later date. Your voting instructions will be kept confidential by the trustee.

Q.	How do I vote my Constellation 401(k) shares?

If you participate in either the Constellation Energy Group, Inc. Employee Savings Plan or the Represented Employee Savings Plan for Nine Mile Point (which we refer to herein as the Constellation Savings Plans), you may give voting instructions to T. Rowe Price, as trustee of the Constellation Savings Plans, by completing and returning the proxy card accompanying this joint proxy statement/prospectus. Your instructions will tell the trustee of the Constellation Savings Plans how to vote the number of shares of Constellation common stock held in your account. If you do not give the trustee of the Constellation Savings Plans voting instructions, your shares will be voted by the trustee of the Constellation Savings Plans in the same proportions as it votes shares for which instructions are received. The trustee will vote your shares in accordance with your duly executed proxy card received by [·], 2006.

You may also revoke previously given voting instructions by [·], 2006, by filing with the trustee of the Constellation Savings Plans either a written notice of revocation or a properly completed and signed proxy card bearing a later date. Your voting instructions will be kept confidential by the trustee.

Q:	Can I revoke my proxy and change my vote?

A:	Yes. You have the right to revoke your proxy at any time prior to the time your shares are voted at your annual meeting. If you are a stockholder of record, your proxy can be revoked in several ways:

•

by timely delivery of a written revocation to your company’s corporate secretary,

•

by submitting another valid proxy bearing a later date, or

•

by attending your annual meeting and voting your shares in person.

You may also revoke your proxy and submit a new proxy by telephone or through the Internet.

However, if your shares are held in the name of your bank, broker, custodian or other recordholder, you must check with your bank, broker, custodian or other recordholder to determine how to revoke your proxy.

Q:	When and where is my annual meeting?

A:	Constellation Stockholder:

The Constellation annual meeting will take place at [·] on [·], 2006 at [·], local time.

A:	FPL Group Shareholder:

Shares of Constellation common stock are traded on the New York Stock Exchange under the symbol “CEG.”

FPL Group, Inc.

700 Universe Boulevard

Juno Beach, Florida 33408

Shares of FPL Group common stock are traded on the New York Stock Exchange under the symbol “FPL.”

The Merger (see page 46)

Upon completion of the merger, FPL Group will become a wholly owned subsidiary of Constellation.

The merger will be completed only after the satisfaction or waiver of the conditions to the completion of the merger discussed below.

The merger agreement is attached as Annex A to this joint proxy statement/prospectus. We encourage you to read the merger agreement carefully and fully, as it is the legal document that governs the merger.

Constellation Stock Split (see page 132)

In connection with the completion of the merger, Constellation will effect a stock split of the shares of Constellation common stock outstanding immediately prior to the completion of the merger. As a result of the stock split, Constellation stockholders will receive 1.444 shares of Constellation common stock for each share of Constellation common stock they held immediately prior to the merger. Constellation will not issue fractional shares resulting from the stock split, but will pay cash in lieu of fractional shares. Constellation does not intend to effect the stock split unless the merger will be completed.

Example: If you currently own 100 shares of Constellation common stock, you will be entitled to receive 144 shares of Constellation common stock and a cash payment for the market value of 0.40 shares at the close of business on the last trading day before the closing date of the merger.

As a result of the merger, Constellation stockholders will continue to hold their shares of Constellation common stock, as adjusted by the stock split.

FPL Group Shareholder Merger Consideration (see page 132)

In the merger, after giving effect to the stock split, FPL Group shareholders will receive one share of Constellation common stock for each share of FPL Group common stock that they held immediately prior to the merger. Upon completion of the merger and stock split, Constellation stockholders prior to the merger will own approximately 40% of the combined company’s outstanding shares of common stock and the FPL Group shareholders prior to the merger will own approximately 60% of the combined company’s outstanding shares of common stock.

Material U.S. Federal Income Tax Consequences of the Merger (see page 104)

As a condition to the completion of the merger, each of Kirkland & Ellis LLP, legal counsel to Constellation, and Cravath, Swaine & Moore LLP, legal counsel to FPL Group, must have delivered its opinion, each dated as of the effective time of the merger, that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and that each of Constellation, FPL Group and CF Merger Corporation (the wholly owned merger subsidiary of Constellation) will be a party to the reorganization within the meaning of Section 368(b) of the Internal Revenue Code. These opinions will be based, in part, on customary factual assumptions and written factual representations. A holder of FPL Group common stock will not recognize any gain or loss for federal income tax purposes upon the exchange of the holder’s shares of FPL Group common stock for shares of Constellation common stock pursuant to the merger. The automatic conversion of each share of Constellation common stock into 1.444 shares of Constellation common stock in the stock split will not be a taxable event to the holders of the Constellation common stock, except with respect to cash received in the stock split in lieu of a fractional share of Constellation common stock.

The federal income tax consequences described above may not apply to you depending on the facts of your situation. You should consult your own tax advisor.

Amended and Restated Constellation Charter (see page 145)

Constellation is proposing to amend and restate its charter to effect various terms of the merger as described in this joint proxy statement/prospectus. The complete text of the amended and restated charter of Constellation substantially in the form to become effective upon completion of the merger transaction is attached as Annex F to this joint proxy statement/prospectus.

Under the merger agreement, completion of the merger is subject to the satisfaction (or, if legally permitted, waiver) of specified closing conditions. Approval by the Constellation stockholders of the amended and restated Constellation charter is one of those conditions. Constellation and FPL Group may not waive the requirement for Constellation stockholders to approve the charter amendment to increase the number of authorized shares of Constellation common stock.

Constellation does not intend to amend and restate the Constellation charter unless the merger will be completed (even if the Constellation stockholders have approved the charter amendment proposal).

Post-Merger Governance and Management (see page 145)

Certain matters relating to post-merger governance and management of the combined company are set forth in the merger agreement, including the following:

•

the combined company will maintain dual headquarters in Juno Beach, Florida and Baltimore, Maryland;

•

Lewis Hay, III, currently Chairman, President and Chief Executive Officer of FPL Group, will become the chief executive officer of the combined company, and Mayo A. Shattuck III, currently Chairman, President and Chief Executive Officer of Constellation, will become chairman of the combined company; and

•

the board of directors of the combined company will be composed of nine persons who served as directors of FPL Group prior to completion of the merger and six persons who served as directors of Constellation prior to completion of the merger.

Required Stockholder Approvals (see page 40)

For Constellation Stockholders:

Approval of the proposal to amend and restate the Constellation charter requires the affirmative vote of holders of a majority of the outstanding shares of Constellation common stock entitled to vote thereon on each amendment contemplated by the amended and restated Constellation charter. Approval of the proposal to issue shares of Constellation common stock as contemplated by the merger agreement requires the affirmative vote of a majority of votes cast on the proposal, provided that the total vote cast on the proposal represents over 50% of all shares of Constellation common stock entitled to vote on the proposal. Approval by the Constellation stockholders of each individual amendment contemplated by the amended and restated Constellation charter and approval of the share issuance proposal are conditions to the completion of the merger under the merger agreement.

For FPL Group Shareholders:

Approval of the proposal to approve the merger agreement requires the affirmative vote of holders of a majority of the outstanding shares of FPL Group common stock entitled to vote thereon. Approval of the proposal to approve the merger agreement is a condition to the completion of the merger.

Recommendations to Constellation Stockholders and FPL Group Shareholders (see pages 55 and 79)

To Constellation Stockholders:

The Constellation board of directors has approved the merger agreement, determined that the merger agreement and the transactions contemplated thereby, including the merger, the issuance of shares of Constellation common stock as contemplated by the merger agreement and the amendment and restatement of the Constellation charter, are advisable, fair to, and in the best interests of Constellation and Constellation stockholders, and recommends that Constellation stockholders vote FOR the share issuance proposal and the charter amendment proposal.

To FPL Group Shareholders:

The FPL Group board of directors has approved the merger agreement, determined that the merger agreement and the transactions contemplated thereby, including the merger, are fair to and in the best interests of FPL Group and FPL Group shareholders, and recommends that FPL Group shareholders vote FOR the proposal to approve the merger agreement.

Opinions of Constellation’s Financial Advisors (see page 60)

Each of Morgan Stanley & Co. Incorporated (which we refer to herein as Morgan Stanley) and Goldman, Sachs & Co. (which we refer to herein as Goldman Sachs) rendered its oral opinion to the Constellation board of directors (subsequently confirmed in writing as of December 18, 2005) that, as of that date and based upon and subject to the assumptions, qualifications and limitations discussed in such opinion, assuming the prior effectiveness of the stock split, the exchange ratio of one share of Constellation common stock for each share of FPL Group common stock pursuant to the merger agreement was fair, from a financial point of view, to the Constellation stockholders. The full text of the opinions of Morgan Stanley and Goldman Sachs, each dated December 18, 2005, which discuss, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations of the review undertaken in connection with each opinion, are attached to this joint proxy statement/prospectus as Annex B and Annex C, respectively. Constellation stockholders are urged to read these opinions carefully in their entirety.

Each of the Morgan Stanley opinion and the Goldman Sachs opinion is addressed to the Constellation board of directors and is directed only to the fairness to the Constellation stockholders, from a financial point of view, of the exchange ratio in the proposed merger. Neither the Morgan Stanley opinion nor the Goldman Sachs opinion constitutes a recommendation to any Constellation stockholder as to how any such stockholder should vote with respect to the merger proposals or any other matter. The opinions also do not address the prices at which shares of Constellation common stock will trade following the completion of the merger or at any other time.

Opinions of FPL Group’s Financial Advisors (see page 84)

On December 16, 2005, Merrill Lynch, Pierce, Fenner & Smith Incorporated (which we refer to herein as Merrill Lynch) rendered its oral opinion to the FPL Group board of directors (subsequently confirmed in writing on December 18, 2005), that, as of that date, and based upon and subject to the assumptions made, matters considered and qualifications and limitations set forth in the written opinion, the exchange ratio of 1.000 share of Constellation common stock for each share of FPL Group common stock provided for in the merger, subject to the prior effectiveness of the stock split whereby each outstanding share of Constellation common stock will be automatically converted into, assuming the effectiveness of the merger, 1.444 shares of Constellation common stock, was fair, from a financial point of view, to the holders of FPL Group common stock. The full text of the written opinion of Merrill Lynch, which sets forth the assumptions made, matters considered and qualifications and limitations on the review undertaken by Merrill Lynch, is attached as Annex D to this joint proxy statement/prospectus. You are urged to read the Merrill Lynch opinion carefully in its entirety.

On December 16, 2005, Lehman Brothers Inc. (which we refer to herein as Lehman Brothers) rendered its oral opinion to the FPL Group board of directors (subsequently confirmed in writing on December 18, 2005) that, as of such date, and based upon and subject to certain matters stated in such written opinion, from a financial point of view, the exchange ratio, assuming the prior effectiveness of the stock split, to be offered to the shareholders of FPL Group in the merger is fair to the shareholders of FPL Group. The full text of the written opinion of Lehman Brothers, which sets forth the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Lehman Brothers in rendering its opinion is attached as Annex E to this joint proxy statement/prospectus. You are urged to read the Lehman Brothers opinion carefully in its entirety.

Each of the Merrill Lynch opinion and the Lehman Brothers opinion is addressed to the FPL Group board of directors. Neither the Merrill Lynch opinion nor the Lehman Brothers opinion constitutes a recommendation to any FPL Group shareholder as to how any such shareholder should vote with respect to the proposed merger or any other matter. The opinions also do not address the prices at which shares of Constellation common stock will trade following the completion of the merger or at any other time.

Risk Factors (see page 22)

There are a number of significant risks related to the merger, including the following:

•

Constellation and FPL Group may be unable to obtain the regulatory approvals required to complete the merger or, in order to obtain these approvals, the combined company may be required to comply with material restrictions or conditions, including requirements that would impose significant additional costs on the business;

•

if the merger is not completed, the trading price of Constellation common stock or FPL Group common stock may decline to the extent that the market prices reflect a market assumption that the merger will be completed;

•

because recently adopted energy legislation in Maryland is still in the process of being implemented, Constellation and FPL Group do not know the impact such legislation will have on the business of Constellation, both as a stand-alone company and, if the merger is completed, as part of the combined company;

•

the value of shares of Constellation common stock will fluctuate;

•

Constellation and FPL Group may be unable to successfully integrate the operations of their respective businesses;

•

Constellation will incur significant transaction, merger-related and restructuring costs in connection with the merger; and

•

the goodwill that will be recorded in connection with the merger could become impaired, which could adversely affect the combined company’s operating results.

Furthermore, there are a number of risks relating to the businesses of Constellation, FPL Group and the combined company.

For a more complete discussion of these risk factors please see “Risk Factors” beginning on page 22.

Conditions to the Completion of the Merger (see page 141)

The completion of the merger depends upon the satisfaction or waiver of a number of conditions, including the following:

•

the approval of the merger agreement by the FPL Group shareholders, and the approval by the Constellation stockholders of the issuance of shares of Constellation common stock as contemplated by the merger agreement and the amendment of the Constellation charter;

•

the absence of any law, judgment, injunction or other order by a governmental entity prohibiting completion of the merger and the absence of any proceeding by any governmental entity seeking such an order;

•

the Constellation stock split having become effective;

•

compliance in all material respects by the parties with their respective obligations under the merger agreement;

•

absence of breaches of the representations and warranties in the merger agreement, subject to materiality and material adverse effect qualifications;

•

the receipt of the required statutory approvals (discussed below) without such approvals imposing terms or conditions that, individually or in the aggregate, would reasonably be expected to (i) have a material adverse effect on either party or the combined company and (ii) materially decrease the long-term value of either party or the combined company; and

•

the absence since December 31, 2004 of any change, event or development that, individually or in the aggregate, has or would reasonably be expected to have a material adverse effect on the other party and would reasonably be expected to materially decrease the long-term value of the other party and its subsidiaries taken as a whole.

Regulatory Matters (see page 106)

The approval of, among others, the following U.S. federal, state and local regulatory authorities must be obtained before the merger can be completed:

•

FERC; and

•

the regulatory agencies in several of the states in which Constellation and/or FPL Group operate electric and/or gas businesses.

In addition, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, the merger cannot be completed until we have made required notifications and provided certain information and materials to the Federal Trade Commission (which we refer to herein as the FTC) and the Antitrust Division of the United States Department of Justice and until specified waiting period requirements have expired. Constellation and FPL Group received early termination of the statutory waiting period on March 24, 2006.

As of the date of this joint proxy statement/prospectus, each of Constellation and FPL Group was in the process of seeking such approvals as are required by applicable law or regulations.

Termination of the Merger Agreement (see page 142)

Constellation and FPL Group may mutually agree to terminate the merger agreement and abandon the merger at any time prior to completion of the merger, whether before or after the FPL Group shareholders have approved the merger agreement or the Constellation stockholders have approved the share issuance proposal or the charter amendment proposal.

In addition, either party could decide, without the consent of the other, to terminate the merger agreement in a number of situations (subject to certain limitations and exceptions), including:

•

if the merger is not completed by December 31, 2006 (which date is automatically extended to June 30, 2007 if the conditions to closing relating to statutory and regulatory approvals of the merger have not been fulfilled but all other conditions to closing are fulfilled or are capable of being fulfilled);

•

if a court or other governmental entity issues an order, decree or ruling or takes any other action permanently prohibiting the completion of the merger and the order, decree or ruling or other action has become final and nonappealable;

•

if the required approval of the Constellation stockholders or FPL Group shareholders is not obtained at the respective stockholder meetings;

•

if any condition to the obligation of such party to complete the merger becomes incapable of being satisfied;

•

if the board of directors of the other party withdraws or adversely modifies its recommendation to its stockholders in favor of the proposals related to the merger; or

•

if the other party breaches its representations, warranties, covenants or other agreements contained in the merger agreement, which breach is not cured within 75 days and would result in a failure of either the closing conditions relating to the breach of representations and warranties or the performance of obligations, each as described above.

Termination Fees (see page 143)

Generally, if following receipt by a party of a competing takeover proposal, the merger agreement is terminated because such party’s board of directors has withdrawn or adversely modified its recommendation to its stockholders in favor of the proposals related to the merger, the merger agreement is terminated because the merger has not been completed by the applicable termination date or such party’s stockholders have failed to approve the proposals related to the merger, then, subject to certain limitations, such party will be required to reimburse the other party for its out-of-pocket expenses and, if such party enters into a competing transaction within a specified period of time, it will be required to pay the other party a termination fee. The termination fee payable by FPL Group to Constellation would be $650 million (reduced by the amount of any expense reimbursement), and the termination fee payable by Constellation to FPL Group would be $425 million (reduced by the amount of any expense reimbursement).

In addition, in circumstances where either party has withdrawn or adversely modified its recommendation to its stockholders in favor of the proposals related to the merger after receipt of a competing takeover proposal and such party’s stockholders fail to approve the proposals related to the merger at a stockholder meeting, such party shall be required to promptly pay a fee of $100 million to the other party, such amount to be credited against the total termination fee of $425 million or $650 million to be paid by Constellation or FPL Group, respectively, if such termination fee becomes payable.

Payment of Dividends Until and After Completion of the Merger (see page 137)

The merger agreement permits each of Constellation and FPL Group to continue to pay regular dividends to its respective stockholders in accordance with past practices (with permitted increases in accordance with the terms of the merger agreement). Constellation and FPL Group expect to continue their respective stated dividend policies until completion of the merger.

Subject to applicable law and fiduciary duties, we expect that the combined company will pay a per share quarterly dividend consistent with the quarterly dividend paid by FPL Group. After adjusting for the stock split, this is a higher per share dividend amount than Constellation has paid historically. (If Constellation’s third quarter 2006 dividend were adjusted for the stock split, the per share dividend amount would be $0.2614.) As a result, we expect that Constellation stockholders will receive an increase in their quarterly dividends following completion of the merger. If the combined company were to pay the same per share quarterly dividend as FPL Group’s third quarter 2006 dividend ($0.375 per share), Constellation stockholders prior to the merger would experience more than a 43% increase in their quarterly dividends from the combined company, as compared to Constellation’s third quarter 2006 dividend, after adjusting for the stock split.

Comparison of the Rights of Constellation Stockholders and FPL Group Shareholders (see page 217)

The rights of Constellation stockholders are governed by Maryland law, and the rights of FPL Group shareholders are governed by Florida law. Moreover, there are differences in the rights of Constellation stockholders and FPL Group shareholders as a result of the provisions of the charter or certificate of incorporation and by-laws of each company.

Constellation Common Stock NYSE Listing (see page 112)

The shares of Constellation common stock to be issued pursuant to the merger will be listed on the New York Stock Exchange under the symbol “CEG.”

No Appraisal Rights (see page 112)

Neither the holders of FPL Group common stock nor the holders of Constellation common stock will have any right to an appraisal of the value of their shares in connection with the merger.

Accounting Treatment for the Merger (see page 103)

The merger will be accounted for as a reverse acquisition under the purchase method of accounting in accordance with the accounting principles generally accepted in the United States of America, which means that FPL Group will be treated as the accounting acquiror and Constellation will be treated as the “acquired” company for financial reporting purposes, and the assets and liabilities of Constellation will be recorded, as of the completion of the merger, at their respective fair values and added to those of FPL Group.

Additional Interests of FPL Group’s and Constellation’s Executive Officers and Directors in the Merger (see page 113)

When FPL Group shareholders and Constellation stockholders consider their board of directors’ recommendation that they vote in favor of the proposals related to the merger, FPL Group shareholders and Constellation stockholders should be aware that FPL Group’s and Constellation’s executive officers and directors may have interests in the merger that may be different from, or in addition to, the interests of FPL Group shareholders or Constellation stockholders. Those interests include, among other things, the accelerated vesting of equity-based awards, specified severance benefits payable under certain circumstances, the appointment of directors and officers to the Constellation board of directors and management team, and in the case of Constellation, the payment of cash for certain equity-based and other awards.

As a result, the directors and officers of FPL Group and Constellation may be more likely to recommend the approval of the merger proposals than if they did not have these interests.

Each of the FPL Group board of directors and the Constellation board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and the merger. FPL Group shareholders and Constellation stockholders should consider these and other interests of FPL Group’s and Constellation’s directors and executive officers that are described in this joint proxy statement/prospectus.

Selected Unaudited Pro Forma Condensed Combined Financial Information

The merger will be accounted for as a reverse acquisition under the purchase method of accounting in accordance with the accounting principles generally accepted in the United States of America, which means that FPL Group will be treated as the accounting acquiror and Constellation will be treated as the “acquired” company for financial reporting purposes and that the assets and liabilities of Constellation will be recorded, as of the completion of the merger, at their respective fair values and added to those of FPL Group. For a more detailed description of purchase accounting, see “The Proposed Merger—Accounting Treatment” beginning on page 103.

Constellation and FPL Group have presented below selected unaudited pro forma condensed combined financial information that reflects the purchase method of accounting and is intended to provide you with a better picture of what their businesses might have looked like had they actually been combined at the beginning of the earliest period presented. The unaudited pro forma condensed combined financial information has been prepared assuming that one share of Constellation common stock had been issued in exchange for each outstanding share of FPL Group common stock pursuant to the merger and 1.444 shares of Constellation common stock had been issued for each outstanding share of Constellation common stock pursuant to the stock split prior to the merger. The unaudited pro forma condensed combined financial information may have been different had the companies actually been combined at the beginning of the earliest period presented. The selected unaudited pro forma condensed combined financial information does not reflect the effect of asset dispositions, if any, or cost savings that may result from the merger. You should not rely on the selected unaudited pro forma condensed combined financial information as being indicative of the historical results that would have occurred had the companies been combined or the future results that may be achieved after the completion of the merger. The following selected unaudited pro forma condensed combined financial information has been derived from, and should be read in conjunction with, the Unaudited Pro Forma Condensed Combined Financial Statements and related notes included in the section “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 150.

Historical and Unaudited Pro Forma Per Share Information

The following table includes selected historical per share information of Constellation and FPL Group and unaudited pro forma condensed combined per share information after giving effect to the merger between Constellation and FPL Group, under the purchase method of accounting, assuming that one share of Constellation common stock had been issued in exchange for each outstanding share of FPL Group common stock pursuant to the merger and 1.444 shares of Constellation common stock had been issued for each outstanding share of Constellation common stock pursuant to the stock split prior to the merger. You should read this information in conjunction with the selected historical financial information included elsewhere in this joint proxy statement/prospectus and the historical financial statements of Constellation and FPL Group and related notes that are incorporated in this joint proxy statement/prospectus by reference. The unaudited Constellation pro forma condensed combined consolidated per share information is derived from, and should be read in conjunction with, the Unaudited Pro Forma Condensed Combined Financial Statements and related notes in the section “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 150. The historical per share information is derived from audited financial statements as of and for the year ended December 31, 2005 and unaudited financial statements for the six months ended June 30, 2006. The unaudited pro forma Constellation per share equivalents are calculated by multiplying the unaudited pro forma combined company per share amounts by 1.444. The pro forma combined outstanding shares are based on the number of shares of Constellation common stock outstanding at June 30, 2006 and December 31, 2005 multiplied by 1.444 and the number of shares of FPL Group common stock outstanding at June 30, 2006 and December 31, 2005.

The unaudited pro forma condensed combined per share information does not purport to represent what the actual results of operations of Constellation and FPL Group would have been had the companies been combined during the period presented or to project Constellation’s and FPL Group’s results of operations that may be achieved after the completion of the merger.

We expect Constellation will continue the dividend policy of FPL Group in effect at the time of completion of the merger. Accordingly, the pro forma cash dividends declared per share of common stock are equal to the dividends declared by FPL Group in the first half of 2006 and during the year ended December 31, 2005.

Comparative Per Share Market Price and Dividend Information

Constellation common stock and FPL Group common stock are each listed on the NYSE. Constellation’s and FPL Group’s ticker symbols are “CEG” and “FPL,” respectively. The following table shows, for the calendar quarters indicated, based on published financial sources: (1) the high and low sale prices of shares of Constellation common stock and FPL Group common stock as reported on the NYSE Composite Transaction Tape and (2) the cash dividends paid or to be paid per share of Constellation common stock and FPL Group common stock. The FPL Group share information for 2004 has been adjusted to reflect the effect of the two-for-one stock split of the FPL Group common stock effective March 15, 2005.

Fourth Quarter	$	62.60	$	50.40	$	0.335	$	48.05	$	40.75	$	0.355

2006
First Quarter	$	60.55	$	54.01	$	0.3775	$	43.42	$	38.85	$	0.375
Second Quarter	$	55.68	$	50.72	$	0.3775	$	41.97	$	37.81	$	0.375
Third Quarter (through August 25, 2006)	$	59.19	$	53.70	$	0.3775	$	44.38	$	40.59	$	0.375

Example: If you owned 1,000 shares of Constellation common stock prior to the merger on the third quarter dividend record date, you would have received a dividend of $0.3775 per share, or $377.50 in total. After the stock split and the merger, you will own 1,444 shares of common stock of the combined company. If the combined company declares and pays a quarterly dividend of $0.375 per share after the merger, which equals FPL Group’s third quarter 2006 dividend, your total quarterly dividend on your 1,444 shares of the combined company common stock would be $541.50, or an increase of approximately 43% over what you would have otherwise received for the third quarter.

Recent Developments

Gas-Fired Plants. In June 2006, Constellation announced that it engaged financial advisors to explore the sale of 3,145 megawatts of natural gas-fired generating plants. The generating assets include Constellation’s

High Desert, Rio Nogales, Holland, University Park, Big Sandy and Wolf Hills plants. These merchant assets are located in California, Texas, Illinois, West Virginia and Virginia. Constellation expects that the proceeds of any such sale will be used for general corporate purposes, including debt reduction. References in this joint proxy statement/prospectus to Constellation’s or the combined company’s power generation capabilities or long-term debt do not reflect a sale of these plants or any reduction in borrowings resulting from the sale. As of the date of this joint proxy statement/prospectus, Constellation has not reached any definitive agreement for the sale of these plants.

Initial Public Offering of Constellation Energy Partners LLC (formerly Constellation Energy Resources LLC). In June 2006, Constellation Energy Partners LLC (which we refer to herein as CEP), a wholly owned limited liability company formed by Constellation, filed a registration statement on Form S-1 with the SEC related to the potential underwritten initial public offering of CEP’s common units. CEP is principally engaged in the acquisition, development and exploitation of natural gas properties. CEP’s existing property is located in the Robinson’s Bend Field in the Black Warrior Basin of Alabama. Although the registration statement relating to the CEP common units has been filed with the Securities and Exchange Commission, it has not yet become effective. The common units may not be sold, nor may offers to buy be accepted, prior to the time the registration statement becomes effective. This joint proxy statement/prospectus does not constitute an offer to sell or the solicitation of any offer to buy any securities of CEP, and there will not be any sale of any such securities in any state in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state.

RISK FACTORS

Constellation stockholders and FPL Group shareholders should carefully read and consider the following risk factors, which we believe are all of the significant risks related to the merger and the anticipated business of the combined company, as well as the other information contained and referred to in this joint proxy statement/prospectus, before voting at their respective annual meetings.

Risks Relating to the Merger

The merger may not be completed, which could adversely affect Constellation’s and/or FPL Group’s business operations and stock prices.

To complete the merger, Constellation stockholders must approve the issuance of shares of Constellation common stock as contemplated by the merger agreement and the amended and restated Constellation charter, and FPL Group shareholders must approve the merger agreement. In addition, each of Constellation and FPL Group must obtain certain approvals and consents from federal and state governmental and regulatory authorities.

Constellation and FPL Group have not yet obtained all of the necessary regulatory clearances. Governmental or regulatory agencies could still seek to block or challenge the merger or could impose restrictions they deem necessary or desirable in the public interest as a condition to approving the merger. If these approvals are not received, or they are not received on terms that satisfy the conditions set forth in the merger agreement, neither Constellation nor FPL Group will be obligated to complete the merger.

The recent adoption of energy legislation in Maryland creates additional uncertainty about the timing of required regulatory approval in Maryland, as well as the potential terms and conditions of such approval, if it is received. In addition, one lawsuit has been filed challenging the constitutionality of certain provisions of the new legislation, and additional lawsuits may be filed in the future. The outcome of such litigation and the additional uncertainty that could result cannot be predicted. This legislation and its impact on the merger approval process are discussed in the section “The Proposed Merger—Regulatory Matters Relating to the Merger” beginning on page 106.

In addition, the merger agreement contains customary other closing conditions, which are described in the section “The Proposed Merger—The Merger Agreement—Conditions” beginning on page 141, which may not be satisfied or waived. If Constellation and FPL Group are unable to complete the merger, Constellation and FPL Group would be subject to a number of risks, including the following:

•

Constellation and FPL Group would not realize the benefits of the proposed merger, including any synergies from combining the two companies;

•

the trading price of Constellation common stock and/or FPL Group common stock may decline to the extent that the current market prices reflect a market assumption that the merger will be completed; and

•

Constellation and FPL Group would continue to be exposed to the general competitive pressures and risks of their businesses, which pressures and risks may be increased if the merger is not completed.

The occurrence of any of these events individually or in combination could have a material adverse effect on the results of operations of Constellation or FPL Group or the trading prices of their common stock.

Constellation and FPL Group will be subject to business uncertainties and contractual restrictions while the merger is pending that could adversely affect their businesses.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Constellation and FPL Group, regardless of whether the merger is eventually completed. Although Constellation and FPL Group have taken steps designed to reduce any adverse effects, these uncertainties may impair

Constellation’s or FPL Group’s ability to attract, retain and motivate key personnel until the merger is completed, or the merger agreement is terminated, and for a period of time thereafter. These uncertainties also could cause customers, suppliers and others that deal with Constellation or FPL Group to seek to change existing business relationships with Constellation or FPL Group.

Employee retention and recruitment may be particularly challenging during the pendency of the merger, as employees and prospective employees may be uncertain about their future roles with the combined company. The departure of existing key employees or the failure of potential key employees to accept employment with either of the companies, despite Constellation’s and FPL Group’s retention and recruiting efforts, could have a material adverse impact on FPL Group’s or Constellation’s business, financial condition and operating results, regardless of whether the merger is eventually completed.

The pursuit of the merger and the preparation for the integration of Constellation and FPL Group places a significant burden on management and internal resources. The diversion of management attention away from day-to-day business concerns and any difficulties encountered in the transition and integration process could have a material adverse impact on FPL Group’s or Constellation’s business, financial condition and operating results, regardless of whether the merger is eventually completed. In general, the integration activities are expected to affect primarily the companies’ competitive businesses and not their regulated utilities.

In addition, the merger agreement restricts each of Constellation and FPL Group, without the other party’s consent, from making certain acquisitions and taking other specified actions until the merger occurs or the merger agreement terminates. These restrictions may prevent Constellation and FPL Group from pursuing otherwise attractive business opportunities and making other changes to their businesses prior to completion of the merger or termination of the merger agreement. Please see the section titled “The Proposed Merger—The Merger Agreement—Covenants” beginning on page 134 for a description of the restrictive covenants applicable to Constellation and FPL Group.

The value of shares of Constellation common stock to be received by Constellation stockholders as a result of the stock split and by FPL Group shareholders in the merger will fluctuate.

Immediately prior to the completion of the merger, each outstanding share of Constellation common stock will be split into 1.444 shares of Constellation common stock (with cash paid in lieu of fractional shares resulting from the stock split). Upon completion of the merger, each outstanding share of FPL Group common stock will be converted into the right to receive one share of Constellation common stock. Both the number of shares of Constellation common stock to be received by Constellation stockholders in the stock split and the number of shares of Constellation common stock issued pursuant to the merger for each share of FPL Group common stock is fixed, and neither number will be adjusted in the event of any change in the market prices of Constellation common stock or FPL Group common stock prior to the effective time of the stock split and the completion of the merger.

The market prices of Constellation common stock and FPL Group common stock immediately prior to the effective time of the stock split and the completion of the merger may vary significantly from their market prices at the date of this joint proxy statement/prospectus and at the date of the annual meetings of the stockholders of Constellation and the shareholders of FPL Group. See “The Introduction—Summary of the Proposed Merger—Comparative Per Share Market Price and Dividend Information” beginning on page 20 for more detailed share price information. These variations may be the result of various factors, including:

•

changes in the business, operations or prospects of Constellation and/or FPL Group;

•

speculation regarding the likelihood that the merger will be completed and the timing of the completion;

•

general market and economic conditions; and

•

litigation and/or regulatory developments.

The stock split and the merger may not be completed until a significant period of time has passed after the Constellation and FPL Group annual meetings. At the time of their respective annual meetings, Constellation stockholders and FPL Group shareholders will not know the exact value of the Constellation common stock that will be received as a result of the stock split or issued in connection with the merger.

Stockholders of Constellation and shareholders of FPL Group are urged to obtain current market quotations for Constellation common stock and FPL Group common stock.

The merger is subject to receipt of consent or approval from governmental entities that could delay or prevent the completion of the merger or impose conditions that could have a material adverse effect on the combined company or that could cause abandonment of the merger.

Completion of the merger is conditioned upon the receipt of consents, orders, approvals or clearances from various state and federal regulatory agencies. We have already received certain of these approvals. The remaining required approvals may not be obtained, or such approvals could be conditioned upon the agreement to restrict the operations of the combined businesses in accordance with specified business conduct rules, to divest generation facilities or to take other actions. In addition, as part of the regulatory approval process, governmental entities may impose significant additional costs on the business of the combined company. In this regard, recently adopted energy legislation in Maryland has created additional uncertainty about the MPSC approval process and may result in substantial delay in the timing of required MPSC approval of the merger or the imposition of terms and conditions that are unfavorable to the combined company, such as a requirement to share expected merger savings with utility customers. See “The Proposed Merger—Regulatory Matters Relating to the Merger” beginning on page 106 for a description of the regulatory approvals necessary in connection with the merger, as well as of recent energy legislation adopted in Maryland.

A substantial delay in obtaining required approvals or the imposition of unfavorable terms or conditions in connection with such approvals could have a material adverse effect on the business, financial condition or results of operations of Constellation, FPL Group or the combined company. In addition, delays or unfavorable terms could lead Constellation or FPL Group to become involved in litigation with one or more governmental entities or may cause Constellation or FPL Group to abandon the merger.

As of the date of this joint proxy statement/prospectus, because we have not yet received all required regulatory approvals (including those from FERC and the MPSC), we do not know the terms or conditions of those approvals or whether we will receive them at all. The annual meetings at which the merger proposals will be considered may take place before all required regulatory approvals have been obtained and before all conditions to such approvals (if any) are known. In this event, if stockholders approve the merger proposals, Constellation and FPL Group subsequently may—without seeking further stockholder approval—agree to conditions included in regulatory approvals, even if such conditions would have an adverse impact on Constellation, FPL Group or the combined company.

Stockholders may not realize all of the anticipated benefits of combining Constellation and FPL Group.

Constellation and FPL Group entered into the merger agreement with the expectation that the merger would result in various benefits, including, among other things, synergies, cost savings and operating efficiencies. Constellation and FPL Group expect the merger to generate potential pre-tax cost synergies of $200 million to $250 million for the combined company on an annualized basis by the end of 2009 (assuming completion of the merger on December 31, 2006 and excluding costs of integration). A substantial majority of these synergies are expected to come from the competitive energy supply businesses. However, governmental entities whose approval is required to complete the merger could require that we share a portion of such merger benefits, from both the utility and competitive energy supply businesses, with utility customers, which would reduce the value of such benefits to the stockholders of the combined companies.

The integration of Constellation and FPL Group following the merger will present significant challenges that may result in a decline in the anticipated potential benefits of the merger.

The merger involves the integration of two companies that previously operated independently, which will likely be time consuming and complex, given the size and complexity of each company and their various business units. Achieving the anticipated benefits from the merger will depend, in part, upon successful integration of the companies, including:

•

integrating the best practices of two companies, including generation and utility operations and staff functions;

•

combining the competitive energy businesses and the energy marketing and trading businesses;

•

the necessity of coordinating geographically separated organizations, systems and facilities;

•

integrating personnel with diverse business backgrounds and organizational cultures;

•

reducing the costs associated with each company’s operations; and

•

preserving important relationships of both Constellation and FPL Group and resolving potential conflicts that may arise.

There can be no assurance that the combined company will be successful in the integration activities or as to the actual level of benefits (including anticipated cost synergies) that will be achieved as a result of such activities.

Each of Constellation and FPL Group will incur significant transaction, merger-related and restructuring costs in connection with the merger.

Constellation and FPL Group expect to incur costs associated with combining the operations of the two companies, as well as transaction fees and other costs related to the merger. The total cost to consummate the transaction is estimated to be approximately $80 million. The amount of transaction costs expected to be incurred is a preliminary estimate and subject to change. The combined company also will incur restructuring and integration costs in connection with the merger. Based on the experience of other merged companies and initial management estimates, costs to integrate computer systems, facilities and insurance arrangements, as well as employee relocation, retention and severance costs, will be approximately $500 million over a period of three years. These merger-related and restructuring cost estimates depend on decisions to be made during integration. As with any merger, these estimates are based on preliminary assessment of integration activities and are likely to change. Additional unanticipated costs may be incurred in the integration of the businesses of Constellation and FPL Group. Depending on the nature of the restructuring activity, the cost may be included in the purchase price allocation to the extent known or as an expense in the period incurred. Although Constellation and FPL Group expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may offset incremental transaction, merger-related and restructuring costs over time, this net benefit, may not be achieved in the near term, or at all.

The combined company will record goodwill that could become impaired and adversely affect the combined company’s operating results.

Under the merger agreement, upon the completion of the merger, FPL Group will become a wholly owned subsidiary of Constellation. However, under generally accepted accounting principles in the United States of America (which we refer to herein as GAAP), FPL Group will be treated as the acquiror for accounting purposes and the merger will be accounted for under the purchase method of accounting as a purchase by FPL Group of Constellation. Under the purchase method of accounting, the total implied purchase price deemed paid by FPL Group in the merger will be allocated to Constellation’s tangible assets and liabilities and identifiable intangible assets, if any are identified, based on their fair values as of the date of completion of the merger. The excess of the deemed purchase price over those fair values will be recorded as goodwill. We expect that the merger will result in the creation of goodwill based upon the application of purchase accounting. To the extent the value of

goodwill or intangibles becomes impaired, the combined company may be required to incur material charges relating to such impairment. Such a potential impairment charge could have a material impact on the combined company’s operating results.

Members of the management and boards of directors of Constellation and FPL Group have interests in the merger that are different from, or in addition to, those of other stockholders and that could have influenced their decision to support or approve the merger.

In considering whether to approve the merger transaction, Constellation stockholders and FPL Group shareholders should recognize that some of the members of management and the boards of directors of Constellation and FPL Group have interests in the merger that differ from, or are in addition to, their interests as stockholders of Constellation and shareholders of FPL Group. These interests are described in “The Proposed Merger—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger” beginning on page 113.

Risks Relating to the Businesses of Constellation, FPL Group and the Combined Company

Constellation’s and FPL Group’s businesses are, and the combined company’s business will be, subject to regulation that will affect operations and costs.

Constellation and FPL Group are, and the combined company will be, subject to regulation by federal and state governmental entities, including FERC, the NRC, the MPSC, the FPSC and the utility commissions of other states in which Constellation and FPL Group have operations. In addition, changing governmental policies and regulatory actions can have a significant impact on Constellation and FPL Group. Regulations can affect, for example, allowed rates of return, requirements for plant operations, recovery of costs, limitations on dividend payments and the regulation or re-regulation of wholesale and retail competition (including but not limited to retail choice and transmission costs).

Florida Power & Light’s base rates for electric service are subject to regulation by the FPSC, and BGE’s distribution rates are subject to regulation by the MPSC, and such rates are effective until new rates are approved. In addition, limited categories of costs are recovered through adjustment charges that are periodically reset to reflect current and projected costs. Inability to recover material costs not included in rates or adjustment clauses, including increases in uncollectible customer accounts that may result from higher gas or electric costs, could have an adverse effect on cash flow and financial position of the combined company.

Recently adopted energy legislation in Maryland mandates rate stabilization that requires BGE to defer the recovery of a portion of its purchased power costs and to phase in the recovery of these costs over a period of years. In addition, the legislation mandates that the MPSC conduct a comprehensive review of Maryland’s deregulated electricity market. Because this energy legislation is still in the process of being implemented, Constellation and FPL Group do not know the impact such legislation will have on the business of Constellation, both as a stand-alone entity and, if the merger is completed, as part of the combined company. For a further discussion of this legislation and its impact on BGE and on the merger, see “The Proposed Merger—Regulatory Matters Relating to the Merger” beginning on page 106.

The regulatory process may restrict Constellation’s or FPL Group’s ability to grow earnings in certain parts of their businesses, cause delays in or affect business planning and transactions and increase the combined company’s costs.

The operation of power generation facilities, including nuclear facilities, involves significant risks that could adversely affect the results of operation and financial condition of the combined company.

Constellation and FPL Group each owns and operates numerous power generation plants. The operation of power generation facilities involves many risks, including start up risks, breakdown or failure of equipment, transmission lines, substations or pipelines, use of new technology, availability of water, the dependence on a

specific fuel source, including the transportation of fuel, the impact of unusual or adverse weather conditions (including natural disasters such as hurricanes) or environmental compliance, as well as the risk of performance below expected or contracted levels of output or efficiency. This could result in lost revenues and/or increased expenses. Insurance, warranties or performance guarantees may not cover any or all of the lost revenues or increased expenses, including the cost of replacement power. For risks relating to nuclear generating facilities, see “—The combined company’s generation business may incur substantial costs and liabilities due to its ownership and operation of nuclear generating facilities” beginning on page 28.

Breakdown or failure of a Constellation or FPL Group operating facility may prevent the facility from performing under applicable power sales agreements. In some cases, this failure could result in termination of the agreement or could expose Constellation or FPL Group to liability for liquidated damages.

The construction of, and capital improvements to, power generation facilities involve substantial risks. Should construction or capital improvement efforts be unsuccessful, the results of operations and financial condition of the combined company could be negatively affected.

Each of Constellation and FPL Group has constructed, and FPL Group is currently constructing, new power generation facilities. In addition, each company is currently undertaking and expects to continue to undertake capital improvement projects at their respective power generation facilities. Constellation’s and FPL Group’s ability to successfully and timely complete their power generation facilities currently under construction, those projects yet to begin construction or capital improvements to existing facilities is contingent upon many variables, including, among other things, receipt of necessary regulatory approvals and availability and cost of qualified labor, materials and equipment. In addition, for facilities under construction in areas affected by hurricanes, risks include physical damage and post-hurricane labor and materials scarcity. If the companies are not able to successfully and timely complete their power generation facilities, then the combined company could be subject to additional costs, termination payments under committed contracts and/or the write-off of its investment in the project or improvement.

The use of derivative contracts by Constellation and FPL Group in the normal course of business could result in financial losses that negatively impact the results of operations of the combined company.

Constellation and FPL Group use derivative instruments, such as swaps, options, futures and forwards, to manage their commodity and financial market risks and to engage in trading activities. The combined company could recognize financial losses as a result of volatility in the market values of these contracts or if a counterparty fails to perform.

In the absence of actively quoted market prices and pricing information from external sources, the valuation of these derivative instruments involves management’s judgment or use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of these contracts. In addition, FPL Group’s use of such instruments for its utility business could be subject to prudency challenges and, if found imprudent, cost recovery could be disallowed by the FPSC. In addition, the combined company may not cover the entire exposure of its assets or positions to market price volatility and the coverage will vary over time. Fluctuating commodity prices may negatively impact the combined company’s financial results and financial position to the extent it has unhedged positions.

The combined company’s competitive energy business will have contractual obligations to certain customers to provide full requirements service, which make it difficult to predict and plan for load requirements and may result in increased operating costs to the business.

The combined companies’ competitive energy business will have contractual obligations to certain customers to supply service to these customers to satisfy all or a portion of such customers’ energy requirements.

The uncertainty regarding the amount of load that the combined company’s competitive energy business must be prepared to supply may increase the operating cost of the combined company’s competitive energy business. A significant under- or over-estimation of load requirements could result in the combined company’s competitive energy business not having enough, or having too much, power to cover its load obligations, in which case it would be required to buy or sell power from or to third parties at prevailing market prices. Those prices may not be favorable and thus could increase its operating costs.

Any divestiture of generation assets or capacity in order to obtain the required regulatory approvals to complete the merger increases the likelihood of the combined company’s generation business not having enough power to cover its load obligations.

Changes to Maryland law that provides for deferral of the recovery by BGE of its costs incurred in satisfying its provider of last resort (POLR) obligations may adversely affect the combined company’s financial results and liquidity.

Under the electric restructuring Maryland enacted in 1999 and various settlements approved by the MPSC in 2003 and 2005, BGE is obligated to serve as the POLR for all retail customers in its service territories for various periods ending between 2007 and 2010. POLR obligations are the obligations of energy delivery businesses to provide electricity to customers that do not choose a competitive supplier and, by their nature, are difficult to quantify.

As the POLR supplier, BGE is required to secure load requirements through a wholesale bidding process sufficient to serve those customers in its service territory in the event that customers do not choose alternate suppliers or if a third party supplier is unable to satisfy its obligations. The settlements provide that BGE be able to recover all of its supply and certain other actual costs of providing POLR service. In June 2006, the Maryland legislature adopted energy legislation requiring BGE to defer recovery of some of its costs of providing residential POLR service in light of the anticipated 72% increase in POLR prices that otherwise would have taken place upon the expiration of the residential rate freeze in June 2006. The legislation’s rate stabilization provisions permit rates to increase to market by no later than January 1, 2008 and allow BGE to recover deferred costs from its customers over a period not to exceed 10 years, with the terms and conditions of rate increases and cost recovery to be determined by the MPSC. The new Maryland legislation is discussed in the section of this joint proxy statement/prospectus entitled “The Proposed Merger—Regulatory Matters Relating to the Merger” beginning on page 106. Any change to this legislation or other subsequent event that limits the recovery by BGE of deferred costs from its customers, or prevents full recovery of future costs, could have a material adverse impact on the financial results and liquidity of Constellation and, if the merger is completed, the combined company.

The combined company’s generation business may incur substantial costs and liabilities due to its ownership and operation of nuclear generating facilities.

Following completion of the merger, it is expected that approximately 18% of the combined company’s owned generation capacity will be nuclear and the combined company will own approximately 9% of the nuclear generation capacity in the United States. (These estimates do not reflect the impact of any divestitures that may be required by governmental authorities to complete the merger or any purchases or sales of generation assets that the companies may complete prior to closing of the merger.) Because of the combined company’s significant portfolio of nuclear plants, the combined company will have greater exposure to risks that adversely affect the nuclear generation industry as compared to others in its industry. These risks include normal operating risks for a nuclear facility and the risks of a nuclear accident.

Nuclear Operating Risks. The ownership and operation of nuclear generating facilities involve routine operating risks, including:

•

mechanical or structural problems;

•

inadequacy or lapses in maintenance protocols;

•

impairment of reactor operation and safety systems due to human or mechanical error;

•

costs of storage, handling and disposal of nuclear materials, including the availability or unavailability of a permanent repository for spent nuclear fuel;

•

regulatory actions, including shut down of units because of public safety concerns, whether at the plants of the combined company or other nuclear operators;

•

limitations on the amounts and types of insurance coverage commercially available;

•

uncertainties regarding both technological and financial aspects of decommissioning nuclear generating facilities; and

•

environmental risks, including risks associated with changes in environmental legal requirements.

Nuclear Accident Risks. In the event of a nuclear accident, the cost of property damage and other expenses incurred may exceed the combined company’s insurance coverage available from both private sources and an industry retrospective payment plan. In addition, in the event of an accident at one of the combined company’s or another participating insured party’s nuclear plants, the combined company could be assessed retrospective insurance premiums (because all nuclear plant operators contribute to a nationwide catastrophic insurance fund). Uninsured losses or the payment of retrospective insurance premiums could each have a material adverse effect on the combined company’s financial condition and results of operations.

The combined company’s competitive energy business may incur substantial costs and liabilities and be exposed to price volatility and counterparty performance risk as a result of its participation in the wholesale energy markets.

Constellation and FPL Group purchase and sell power and fuel in markets exposed to significant risks, including price volatility for electricity and fuel and the credit risks of counterparties with which the companies enter into trades.

The companies use (and the combined company will use) various hedging strategies in an effort to mitigate many of these risks. However, hedging transactions do not guard against all risks and are not always effective, as they are based upon predictions about future market conditions. The inability or failure to effectively hedge assets or fuel or power positions against changes in commodity prices, interest rates, counterparty credit risk or other risk measures could significantly impair future financial results.

Exposure to electricity price volatility. Constellation and FPL Group buy and sell electricity in both the wholesale bilateral markets and spot markets, which expose the companies to the risks of rising and falling prices in those markets, and their cash flows may vary accordingly. At any given time, the wholesale spot market price of electricity for each hour is generally determined by the cost of supplying the next unit of electricity to the market during that hour. This is highly dependent on the regional generation market. In many cases, the next unit of electricity supplied would be supplied from generating stations fueled by fossil fuels, primarily coal, natural gas and oil. Consequently, the open market wholesale price of electricity may reflect the cost of coal, natural gas or oil plus the cost to convert the fuel to electricity and an appropriate return on capital. Therefore, changes in the supply and cost of coal, natural gas and oil may impact the open market wholesale price of electricity.

A portion of Constellation’s and FPL Group’s power generation facilities operate wholly or partially without long-term power purchase agreements. As a result, power from these facilities is sold on the spot market or on a short-term contractual basis, which if not fully hedged may affect the volatility of Constellation’s or FPL Group’s financial results.

Exposure to fuel cost volatility. Currently, Constellation’s and FPL Group’s power generation facilities purchase a portion of their fuel through short-term contracts or on the spot market. Fuel prices can be volatile, and the price that can be obtained for power produced from such fuel may not change at the same rate as fuel costs. As a result, fuel price increases may adversely affect results of operations.

Exposure to counterparty performance. Constellation’s and FPL Group’s competitive energy businesses enter into trades and hedging transactions with numerous third parties (commonly referred to as “counterparties”). In such arrangements, the companies are exposed to the credit risks of their counterparties and the risk that one or more counterparties may fail to perform their obligations to make payments or deliver fuel or power. These risks are enhanced during periods of commodity price fluctuations, such as is currently being experienced in the United States. Defaults by suppliers and other counterparties may adversely affect the companies’ results of operations.

Constellation and FPL Group often rely on single suppliers and at times on single customers, exposing Constellation and FPL Group to significant financial risks if either should fail to perform its obligations.

Constellation and FPL Group often rely on a single supplier for the provision of fuel, water and other services required for operation of a facility, and at times they rely on a single customer or a few customers to purchase all or a significant portion of a facility’s output, in some cases under long-term agreements that provide the support for any project debt used to finance the facility. The failure of any one supplier or customer to fulfill its contractual obligations could negatively impact the combined company’s financial results. Consequently, the combined company’s financial performance depends on the continued performance by suppliers and customers of their obligations under these long-term agreements.

Constellation and FPL Group operate in the competitive energy industries created by federal and state restructuring initiatives. If competitive restructuring of these industries is reversed, discontinued, restricted or delayed, Constellation and FPL Group’s business prospects and financial condition could be materially adversely affected.

The regulatory environment applicable to the electric and natural gas industries has undergone substantial changes as a result of restructuring initiatives at both the state and federal levels. These initiatives have had a significant impact on the nature of the electric and natural gas industries and the manner in which their participants conduct their businesses. Constellation and FPL Group have targeted the competitive segments of the electric and natural gas industries created by these initiatives.

Due to recent events in the energy markets, energy companies have been under increased scrutiny by state legislatures, regulatory bodies, capital markets and credit rating agencies. This increased scrutiny could lead to substantial changes in laws and regulations affecting Constellation and FPL Group, including modifications to the auction processes in competitive markets and new accounting standards that could change the way we are required to record revenues, expenses, assets and liabilities. The recently enacted Maryland energy legislation is one example of how these laws can change. Constellation and FPL Group cannot predict the future development of regulation in these markets or the ultimate effect that this changing regulatory environment will have on the combined company’s business.

Certain restructured markets have experienced supply problems and/or price volatility. These conditions have been the subject of a significant amount of publicity, much of which has been critical of the market restructuring initiatives. The recent adoption in Maryland of energy legislation was a response to these market conditions. The legislation, among other things, introduces a temporary cap on rate increases and requires a reconstituted MPSC to evaluate the status of Maryland’s deregulated electricity market, including the implications of requiring or allowing utilities to construct or acquire generating facilities and to re-evaluate the allowance for stranded costs under the Maryland Electric Customer Choice and Competition Act of 1999.

In other markets, including California, proposals have been made by governmental agencies and/or other interested parties to re-regulate areas of these markets which have previously been deregulated. Additional proposals to re-regulate may be made and legislative or other attention to the electric and natural gas restructuring process may delay or reverse the deregulation process.

If competitive restructuring of the electric and natural gas markets is reversed, discontinued, restricted or delayed, or if recently enacted Maryland energy legislation is implemented in a manner adverse to Constellation, Constellation’s and FPL Group’s business prospects and financial condition could be negatively impacted.

The combined company’s results may be harmed if transportation and transmission availability is limited or unreliable.

Constellation and FPL Group have business operations in various regions of the United States, and Constellation has business operations in Canada, Europe, Asia and Australia. As a result, the combined company will depend on transportation and transmission facilities owned and operated by others to deliver the electricity, coal and natural gas it sells to the wholesale and retail markets, as well as the coal and natural gas it purchases to supply some of its electric generation facilities. If transportation or transmission is disrupted, or transportation or transmission capacity is inadequate, the combined company’s ability to sell and deliver products may be hindered and its business may be materially adversely affected.

The combined company’s financial results may fluctuate on a seasonal and quarterly basis or as a result of severe weather.

Weather conditions affect Constellation’s and FPL Group’s businesses. The combined company’s overall operating results may fluctuate substantially on a seasonal basis. The pattern of this fluctuation may change depending on the nature and location of any facilities the combined company acquires and the terms of any contract to which it becomes a party.

Weather conditions directly influence the demand for electricity and natural gas and affect the price of energy commodities. Weather also can affect the production of electricity at wind and hydro-powered facilities. Generally, demand for electricity peaks in winter and summer and demand for gas peaks in winter. Typically, when winters are warmer than expected and summers are cooler than expected, demand for energy is lower, resulting in less electric and gas consumption than forecasted.

Depending on prevailing market prices for electricity and gas, these and other unexpected conditions may reduce the combined company’s revenues and results of operations. Results of operations will be substantially dependent on weather conditions and may make period-to-period comparisons less relevant. Any substantial fluctuations in operating results for fiscal quarters or on a year-to-year basis may cause the combined company’s stock price to be volatile.

Severe weather can affect the combined company’s results of operation. Severe weather can be destructive, causing outages and/or property damage. This could require the combined company to incur additional costs. Catastrophic weather, such as hurricanes, could impact the combined company’s or its customers’ operating facilities, communication systems and technology. Unfavorable weather conditions may have a material adverse effect on the combined company’s financial condition and results of operations.

A downgrade in the combined company’s credit ratings could negatively affect its ability to access capital and/or operate its wholesale and retail competitive supply businesses.

Constellation, FPL Group and their respective subsidiaries rely on access to capital markets as a source of liquidity for capital requirements not satisfied by operating cash flows. If any of their, or the combined company’s, credit ratings were to be downgraded, especially below investment grade, its ability to raise capital on favorable terms, including the commercial paper markets, could be hindered, and their and the combined company’s borrowing costs would increase. Additionally, the business prospects of their wholesale and retail competitive supply businesses, which in many cases rely (or will rely) on the creditworthiness of Constellation or FPL Group, or that of the combined company, would be negatively impacted. Some of the factors that affect credit ratings are cash flows, liquidity and the amount of debt as a component of total capitalization.

In addition, the ability and timing of the regulated utility businesses of Constellation and FPL Group to recover their costs of providing service could have a material adverse effect on the credit ratings of the utilities and of the combined company.

Reduced liquidity in the markets in which Constellation and FPL Group operate could impair the combined company’s ability to appropriately manage the risks of its operations.

Each of Constellation and FPL Group is an active participant in energy markets through its competitive energy businesses. The liquidity of regional energy markets is an important factor in their ability to manage risks in these operations. Over the past several years, several competitive energy businesses have ended or significantly reduced their competitive energy activities as a result of several factors, including government investigations, changes in market design and deteriorating credit quality. As a result, several regional energy markets experienced a significant decline in liquidity. While there have been recent improvements in liquidity, future reductions in liquidity may restrict the combined company’s ability to manage its risks and could affect its operating results and financial position.

The combined company’s ability to successfully identify, complete and integrate acquisitions is subject to significant risks, including the effect of increased competition resulting from the consolidation of the power industry.

The combined company is likely to encounter significant competition for acquisition opportunities that may become available as a result of the consolidation of the power industry. In addition, the combined company may be unable to identify attractive acquisition opportunities at favorable prices and to successfully and timely complete and integrate them.

Market performance will affect the combined company’s decommissioning trust funds and benefit plan asset values.

The performance of the capital markets will affect the value of the assets that are held in trust to satisfy the combined company’s future obligations under its pension and post-retirement benefit plans and to decommission nuclear generating plants. A decline in the market value of those assets, as was experienced from 2000 to 2002, may increase the combined company’s funding requirements for these obligations.

War and threats of terrorism and catastrophic events that could result from terrorism may impact the combined company’s results of operations in unpredictable ways.

Constellation and FPL Group cannot predict the impact that any future terrorist attacks may have on the energy industry in general and on the combined company in particular. In addition, any retaliatory military strikes or sustained military campaigns may affect the combined company’s operations in unpredictable ways, such as changes in insurance markets and disruptions of fuel supplies and markets, particularly oil. The possibility alone that infrastructure facilities, such as electric generation, electric and gas transmission and distribution facilities, would be direct targets of, or indirect casualties of, an act of terrorism may affect the combined company’s operations. Such activity may have an adverse effect on the United States economy in general. A lower level of economic activity might result in a decline in energy consumption, which may adversely affect the combined company’s revenues or restrict its future growth. Instability in the financial markets as a result of terrorism or war may affect the combined company’s stock price and its ability to raise capital.

The combined company may incur substantial costs to fulfill its obligations related to environmental matters.

Subsidiaries of Constellation and FPL Group are subject to extensive federal, state and local environmental statutes, rules and regulations relating to air quality, water quality, waste management, wildlife protection, the management of natural resources and the protection of human health and safety. These could, among other things, require additional pollution control equipment, limit the use of certain fuels, restrict the output of certain facilities, or otherwise increase the companies’ costs. Compliance with current environmental requirements require the companies to incur significant capital expenditures, operating and other costs. These expenditures and costs are expected to increase in the future as a result of regulatory changes. For example, in April 2006, the

State of Maryland adopted the Healthy Air Act, which will require, among other things, more rapid emission reductions by Maryland power generation facilities (including those owned and operated by Constellation) than is required by current federal laws and regulations. Additional changes in federal, state and local environmental laws and rules are currently being considered and are expected in the future.

Subsidiaries of Constellation and FPL Group are subject to liability under environmental laws for the costs of remediating environmental contamination. Remediation activities include the cleanup of current facilities, former properties, including former manufactured gas plants, and offsite waste disposal facilities. The remediation costs may negatively impact the combined company’s financial results. Also, subsidiaries of Constellation and FPL Group are currently involved in proceedings relating to sites where hazardous substances have been released and may be subject to additional proceedings in the future.

Subsidiaries of Constellation and FPL Group are subject to legal proceedings by individuals alleging injury from exposure to hazardous substances. Depending upon the outcome of these proceedings, the liabilities incurred could be material to the combined company’s financial results. Additional proceedings could be filed against Constellation and FPL Group in the future.

The combined company’s ability to obtain insurance and the terms of any available insurance coverage could be affected by national, state or local events and company-specific events.

The combined company’s ability to obtain insurance, and the cost of and coverage provided by such insurance, could be affected by national, state or local events as well as company-specific events. For example, due to the high cost and limited coverage available from third-party insurers, FPL Group historically has not obtained, and the combined company may not be able to obtain, insurance coverage on its transmission and distribution property against catastrophic events, such as hurricanes. Storm and property insurance reserve funds may not cover all storm costs incurred by the combined company upon the occurrence of catastrophic events, and such uninsured costs may have a material adverse effect on the combined company’s financial condition.

Customer growth in service areas may affect results of operations.

Constellation’s and FPL Group’s results of operations are affected by the growth in customer accounts in Florida Power & Light’s and BGE’s service areas, respectively. Customer growth can be affected by population growth as well as economic factors, including job and income growth, housing starts and new home prices. Customer growth will directly influence the demand for electricity and the need for additional power generation and power delivery facilities of the combined company.

The combined company is subject to employee workforce factors that could affect its businesses and financial condition.

The combined company is subject to employee workforce factors, including loss or retirement of key executives and other employees, availability of qualified personnel, collective bargaining agreements with union employees and work stoppage that could affect the businesses and financial condition of the combined company.

received with broker non-votes on some but not all matters, count as present.

Under the NYSE rules, if your broker holds your shares in its name, your broker may not vote your shares on, in the case of Constellation, the share issuance proposal, the charter amendment proposal or the stockholder proposal, absent instructions from you. In the case of FPL Group, if your broker holds your shares in its name, your broker may not vote your shares on the proposal to approve the merger agreement, absent instructions from you. Without your voting instructions on those proposals, a “broker non-vote” will occur.

Required Votes for the Constellation and FPL Group Proposals

Company

Vote Necessary

Constellation:

Proposal 1 (Share Issuance Proposal)

Approval of the proposal to issue shares of Constellation common stock as contemplated by the merger agreement requires the affirmative vote of a majority of votes cast on the proposal, provided that the total vote cast on the proposal represents over 50% of all shares of Constellation common stock entitled to vote on the proposal. Abstentions and “broker non-votes” have no effect on this proposal, except that they will not constitute votes cast for purposes of obtaining the required minimum vote.

Proposal 2 (Charter Amendment Proposal)

Approval of the proposal to amend and restate the Constellation charter requires the affirmative vote of holders of at least a majority of the outstanding shares of Constellation common stock entitled to vote thereon on each amendment contemplated by the amended and restated Constellation charter. Abstentions and “broker non-votes” have the same effect as a vote AGAINST this proposal.

Proposal 3 (Election of Directors)

Directors are elected by a plurality of the votes cast, assuming a quorum is present. Abstentions and “broker non-votes” have no effect on this proposal, except they will be counted as having been present for purposes of determining the presence of a quorum.

Proposal 4 (Proposal to Ratify Independent Registered Public Accounting Firm)

Approval of the proposal to ratify PricewaterhouseCoopers LLP as Constellation’s independent registered public accounting firm for the year 2006 requires the affirmative vote of a majority of the votes cast by holders of shares of Constellation common stock present in person or by proxy at the meeting and entitled to vote, assuming a quorum is present. Abstentions and “broker non-votes” have no effect on this proposal, except they will be counted as having been present for purposes of determining the presence of a quorum.


Company		Vote Necessary
		Proposal 5 (Stockholder Proposal) Approval of the stockholder proposal requires the affirmative vote of a majority of the votes cast by holders of shares of Constellation common stock present in person or by proxy and entitled to vote at the meeting, assuming a quorum is present. Abstentions and “broker non-votes” have no effect on this proposal, except they will be counted as having been present for purposes of determining the presence of a quorum.

		Adjournments; Postponements Approval of a proposal by the Constellation board of directors to adjourn or postpone the meeting requires the affirmative vote of a majority of the votes cast by holders of shares of Constellation common stock present in person or by proxy at the meeting, whether or not a quorum is present.
		Other Matters Properly Before the Meetings Approval of any other matters that may properly come before the meeting requires the affirmative vote of a majority of the votes cast by holders of shares of Constellation common stock present in person or by proxy at the meeting and entitled to vote (unless a greater vote is required for the matter pursuant to Constellation’s charter or by-laws or applicable law), assuming a quorum is present.

FPL Group:		The Florida Business Corporation Act (which we refer to herein as the FBCA) provides that directors are elected by a plurality of the votes cast and that all other matters are approved if the votes cast in favor of the action exceed the votes cast against the action (unless the matter is one for which the FBCA or the articles of incorporation require a greater vote). Therefore, under the FBCA, abstentions and broker non-votes have no legal effect on whether a matter is approved. However, the FPL Group bylaws, which were adopted prior to the current FBCA and remain in effect, provide that any matter, including the election of directors, is to be approved by the affirmative vote of a majority of the total number of shares represented at the meeting and entitled to vote on such matter (unless the matter is one for which the FBCA or some other law or regulation expressly requires or permits the FPL Group board of directors to require a greater vote, or the FPL Group articles of incorporation or bylaws require a greater or different vote). Under the FBCA, the affirmative vote of a majority of the shares of FPL Group common stock outstanding and entitled to be cast is required to approve the merger agreement. As to any other matter voted on by shareholders at the annual meeting, including the election of directors, the affirmative vote of a majority of the total number of shares represented at the meeting and entitled to vote is required. Abstentions and, with respect to the election of directors, votes to withhold, have the same effect as a vote against a matter. Broker non-votes received by FPL Group count as present for purposes of establishing a quorum and have the same effect as a vote *AGAINST* the proposal to approve the merger agreement. Because brokers have discretionary voting power for the other proposals scheduled to be voted on, including the election of directors, there can be no broker non-votes on such proposals. If other matters are properly brought before the annual meeting as to which brokers do not have discretionary voting power, any broker non-votes will have no legal effect with respect to such matters.

General

In the merger, FPL Group will merge with a wholly owned subsidiary of Constellation. Immediately prior to the merger, Constellation will effect a stock split whereby each outstanding share of Constellation common stock

THE MERGER WILL NOT BE COMPLETED UNLESS, AMONG OTHER THINGS, THE FPL GROUP SHAREHOLDERS APPROVE THE MERGER AGREEMENT.

Background of the Merger

The senior management teams and boards of directors of each of Constellation and FPL Group actively monitor and assess developments in the energy industry and are generally aware of the business activities of other major energy companies, including each other. Executives from each of Constellation and FPL Group periodically interact with each other at industry gatherings and as part of various energy industry organizations. In addition, Messrs. Shattuck and Hay have served as directors of Capital One Financial Corporation since October 2003, and they also have served as directors of the Institute of Nuclear Power Operations. As a result of these roles, they see and speak with each other several times each year.

Over the past several years, senior management and the boards of directors of each of Constellation and FPL Group have regularly reviewed strategic opportunities in the energy industry in response to developments within

their respective businesses, industry trends, competitive conditions and changes in legislation and regulation. These reviews have included periodic assessments of potential business combinations with other energy companies. This included Constellation’s review in early 2002 of an unsolicited offer from another integrated energy company to acquire Constellation at an approximately 20% premium to Constellation’s then trading price of approximately $28.75. Constellation determined that, in light of what it believed was the low valuation attributed to Constellation at that time, the negative effect such an acquisition would have on its employees and the State of Maryland in terms of potential job losses, and the business plan which was being developed by a new management team led by Mr. Shattuck as the new chief executive officer, it was in the best long-term interests of Constellation to remain independent and seek to implement the business plan. During the next several years, Constellation implemented its business plan, including the growth of its competitive wholesale energy business, the acquisition and growth of its retail power and gas businesses and the acquisition of the Nine Mile Point and R.E. Ginna Nuclear power plants.

In May 2005, Messrs. Shattuck and Hay had a number of general discussions by telephone about recent developments in the energy industry. Among other things, they discussed recent energy industry transactions and the prospects for the adoption of comprehensive federal energy legislation, including the potential impact that the repeal of the Public Utility Holding Company Act might have on the industry. During these conversations, they also discussed strategic trends and opportunities within their respective companies and in the energy industry generally. In addition, they discussed briefly, and generally, the possibility of a strategic transaction between FPL Group and Constellation. Although no specific potential terms or proposals were discussed, they agreed to meet in June to discuss this possibility further.

On June 15, 2005, Messrs. Shattuck and Hay met in New York City. They discussed primarily high-level issues relating to the companies’ businesses and a potential business combination, including strategic, management and governance matters. They also discussed the status of FPL Group’s pending rate case in Florida. No agreements were reached, but both expressed interest in continuing these discussions.

On July 12, 2005, Messrs. Shattuck and Hay met in Baltimore. Mr. Hay provided Mr. Shattuck with a summary outline of possible key terms for a potential stock-for-stock merger reflecting what Mr. Hay described as a “modest premium” for Constellation stockholders. Their discussion focused primarily on the potential strategic benefits of a combination of the two companies’ businesses and various governance issues that would be raised by a merger.

On July 22, 2005, during a regularly scheduled Constellation board of directors meeting held by telephonic conference call, Mr. Shattuck (in executive session) briefed the members of the Constellation board of directors about his discussions to date with Mr. Hay. Specific terms of a potential transaction were not discussed, and no action of the board of directors was requested. Mr. Shattuck indicated his expectation that he would have further discussions with Mr. Hay and that the senior management team would begin to evaluate FPL Group more closely as a potential merger partner based on publicly available information.

On July 29, 2005, a regularly scheduled FPL Group board of directors meeting was held. At such meeting, Mr. Hay summarized for the directors his discussions to date with Mr. Shattuck regarding a potential merger and indicated that FPL Group’s management would continue to evaluate Constellation’s businesses and the potential strategic benefits of a combination of the two companies.

On August 18, 2005, Messrs. Shattuck and Hay met in Juno Beach and continued to discuss strategic and business considerations of a possible merger, as well as to review the potential terms and timetable for such a transaction.

During September and October, senior management of Constellation and FPL Group had numerous discussions regarding a potential merger in addition to those described below.

On September 1, 2005, Messrs. Shattuck and Hay spoke by telephone. They discussed the terms of FPL Group’s recent settlement of its rate case in Florida. They generally agreed that if they were to pursue a

transaction, the combined company would commit to maintain dual headquarters in Baltimore and Juno Beach. They also agreed that, subject to confirmatory due diligence by FPL Group, the combined company would use the Constellation name. In addition, they discussed potential pricing for the merger that would provide Constellation stockholders with a premium consistent with comparable market transactions in the energy industry. They also agreed that the companies should enter into a mutual confidentiality agreement and begin to exchange business information. Over the next several days, Messrs. Irving B. Yoskowitz, Executive Vice President and General Counsel of Constellation, and Edward F. Tancer, Vice President and General Counsel of FPL Group, negotiated a confidentiality agreement that both companies signed on September 6, 2005.

On September 21, 2005, senior executives of FPL Group and Constellation met in Baltimore to exchange initial presentations on their companies’ respective businesses.

On September 26, 2005 and October 5, 2005, Messrs. Shattuck and Hay continued their discussions by phone of a possible merger, including with respect to a possible management team for the combined company as well as economic, governance and other key terms. They also discussed the possibility of Mr. Hay attending a Constellation board of directors meeting.

During September, October and November, senior management of each of Constellation and FPL Group met regularly with their respective outside legal, financial and other outside professional advisors to discuss the structure of a potential merger, regulatory considerations and approvals, potential synergies and other matters that would arise in the course of a potential merger between the two companies.

On October 1, 2005, FPL Group engaged Merrill Lynch to act as its financial advisor in connection with a possible merger with Constellation.

Throughout the month of October, the companies exchanged and discussed high-level information about their businesses, including with respect to financial, operational, accounting and compensation and benefits matters.

On October 14, 2005, at a regularly scheduled meeting of the FPL Group board of directors, management updated the board of directors on the status of its preliminary discussions with Constellation and made a presentation regarding Constellation’s businesses and the potential merger. After engaging in discussion, the FPL Group board of directors indicated that management should continue the discussions with Constellation. Mr. Hay telephoned Mr. Shattuck on October 19, 2005 to update him on the outcome of the FPL Group board of directors meeting and to discuss a possible timetable for due diligence and the negotiation of definitive agreements.

On October 21, 2005, at an executive session of a regularly scheduled meeting of the Constellation board of directors, the senior management of Constellation provided the directors with a high-level overview of a possible merger and FPL Group’s business, financial condition and management based upon publicly available information and information provided by FPL Group over the past several weeks. The board of directors discussed with management the strategic rationale for a possible merger with FPL Group, the matters that Messrs. Shattuck and Hay had been discussing and a possible timetable for due diligence and the negotiation of definitive agreements. The Constellation board of directors instructed management to proceed with comprehensive due diligence and continue its discussions of a potential merger with FPL Group. The board of directors emphasized the significance of ensuring that a combined company would continue to have a meaningful presence in, and substantial financial and employment commitments to, Baltimore and the State of Maryland.

On October 25, 2005, Mr. Shattuck telephoned Mr. Hay to discuss with him the results of the Constellation board of directors meeting. At the conclusion of the call, it was agreed that both companies would proceed with more intensive due diligence over the next few weeks and would ask their outside legal counsel to begin preparing transaction documents.

On October 27, 2005, Constellation engaged Morgan Stanley as its financial advisor with respect to a possible merger with FPL Group.

On October 31, 2005, certain senior executives of Constellation and FPL Group (other than Messrs. Shattuck and Hay) held a telephone conference call with representatives of Morgan Stanley and Merrill Lynch regarding possible financial terms of a potential merger and additional financial and operational due diligence matters.

During November, Kirkland & Ellis LLP, outside legal counsel for Constellation, and Cravath, Swaine & Moore, LLP, outside legal counsel for FPL Group, had several discussions, including with respect to legal documentation, the possible timing of negotiations of a merger agreement and due diligence matters.

On November 3, 2005, certain senior executives of Constellation and FPL Group (other than Messrs. Shattuck and Hay) met in Baltimore to review financial results for the two companies and other financial and accounting matters.

On November 4, 2005, the Compensation Committee of the Constellation board of directors met to discuss proposed amendments to existing change in control severance agreements with Constellation’s executive officers, which originally had been presented to the Committee at its October 20, 2005 meeting for review and consideration. Representatives of Constellation’s legal and human resources staffs, the Committee’s outside compensation consultant, Hewitt Associates LLC, and the Committee’s outside legal counsel for compensation matters, Sullivan & Cromwell LLP, attended portions of this meeting. At the meeting, the Committee approved the proposed amendments and directed management to prepare amended and restated change in control severance agreements to reflect these amendments. For a discussion of these amended and restated agreements, see “—Additional Interests of Constellation’s Directors and Executive Officers in the Merger—Change in Control Severance Agreements” beginning on page 120.

On November 4, 2005, Messrs. Hay and Shattuck met in Baltimore to further discuss the potential merger. They reviewed a revised summary outline and discussed transaction structure, pricing, management and governance issues, executive compensation matters and a proposed schedule for further due diligence and the negotiation of a definitive agreement. During the conversation, they discussed that the transaction would be a stock-for-stock deal involving a fixed exchange ratio and that Constellation stockholders would receive a premium consistent with comparable market transactions. Mr. Hay indicated that the merger must in any event be accretive to FPL Group. In addition, they agreed that each of Messrs. Hay and Shattuck would maintain offices in Baltimore and Juno Beach and discussed the size of the combined company board of directors and various other governance matters. They also discussed their respective management roles in a combined business, generally agreeing that Mr. Hay would be the chief executive officer and Mr. Shattuck would serve as an executive chairman. In addition, they agreed that Mr. Shattuck initially would have management responsibility for the competitive energy business. They also discussed additional senior executive personnel matters and various other compensation matters.

On or about November 7, 2005, the companies established an electronic data room to be used for legal, financial and operational due diligence, and both companies posted extensive and detailed information about their businesses in that data room throughout November and December. During this period, representatives of the companies, along with their outside legal, financial and accounting advisors, exchanged requests for information and responses to those requests, exchanged information supplementally and reviewed and discussed all such information.

On November 9, 2005, certain senior executives of Constellation and FPL Group (other than Messrs. Shattuck and Hay) met in Florida to review and discuss FPL Group’s businesses. The FPL Group management team delivered a presentation on the company’s wind and other businesses, and there was a general discussion of FPL Group’s business plans, as well as legislative and regulatory matters in Florida. The next day, Ms. Follin Smith, Executive Vice President, Chief Financial Officer and Chief Administrative Officer of Constellation, met with Mr. Hay.

On November 17, 2005, certain senior executives of Constellation and FPL Group (other than Messrs. Shattuck and Hay) met in Washington, DC to review and discuss business, financial, operational, tax, personnel, compensation and risk management issues regarding Constellation. A significant portion of the discussion involved a presentation by Constellation executives of Constellation’s competitive energy business and its risk management and energy trading policies and practices. The executives also discussed litigation matters relating to both Constellation and FPL Group.

On November 21, 2005, Cravath sent to Kirkland & Ellis a first draft of a proposed merger agreement.

On November 30, 2005, Messrs. Thomas F. Brady, Executive Vice President, Corporate Strategy and Retail Competitive Supply of Constellation, and James L. Robo, Vice President, Corporate Development and Strategy of FPL Group and President of FPL Energy, met with representatives of Morgan Stanley and Merrill Lynch in New York City to discuss potential economic terms. Based on the discussion, the parties decided that negotiations would continue with the understanding that the premium to be received by Constellation stockholders would be between 13-17%. Later that day, Messrs. Shattuck and Hay spoke by telephone to discuss, among other matters, the overall status of due diligence and negotiations, including various items in the draft merger agreement. They also discussed certain senior executive personnel and compensation matters, various governance matters, the status of pending environmental legislation in Maryland and the two companies’ recently released third quarter financial results.

On December 2, 2005, at a regularly scheduled meeting of the Constellation board of directors, the senior management team updated the directors on due diligence, the status of discussions regarding terms of a potential merger with FPL Group and the key open due diligence items remaining to be addressed by each company. Representatives of Kirkland & Ellis reviewed the board of directors’ fiduciary obligations in the context of a potential merger transaction, discussed the potential key terms of a merger agreement and outlined for the board of directors the various regulatory approvals that would be required and the likely timing for securing such approvals. Representatives of Morgan Stanley discussed with the board of directors various preliminary valuation matters regarding a potential transaction based on discussions completed to date.

At the conclusion of the meeting, the Constellation board of directors went into executive session (with Mr. Shattuck remaining in attendance). Mr. Hay and four of FPL Group’s directors joined that session, at the invitation of the Constellation board of directors. They discussed strategic considerations and a range of governance and management matters that would be raised by a merger.

On December 3, 2005, Messrs. Hay and Shattuck discussed by telephone their and their company’s respective directors’ impressions of the December 2, 2005 meetings, as well as other matters.

On December 6, 2005, Kirkland & Ellis sent to Cravath proposed revisions to the draft merger agreement. The proposed revisions did not address economic or governance matters. Representatives of the two law firms discussed the proposed revisions by telephone on December 7, 2005. Later that day, Cravath distributed a proposed exhibit to the merger agreement (which became Exhibit C to the final agreement) addressing certain governance matters for the combined companies, including the management roles to be played by each of Messrs. Shattuck and Hay, the proposed composition of the combined company’s board of directors and the standing board of directors committees, the combined company’s dual headquarters and the primary locations for specific corporate and operating business functions and various other governance matters.

On December 6, 2005, at a special meeting of the FPL Group board of directors, the senior management team of FPL Group updated the board of directors on the possible merger with Constellation. Mr. Hay described the status of discussions and other members of senior management made a presentation regarding certain business and financial matters relating to FPL Group, Constellation and the potential merger as well as an update regarding due diligence. In addition, Merrill Lynch made a financial presentation regarding the potential merger. The board of directors indicated that management should complete due diligence and continue discussions with

Constellation. The board of directors also approved the hiring of Lehman Brothers as its own advisor, separate from Merrill Lynch, which was acting as overall financial advisor to FPL Group, to provide an additional fairness opinion with respect to the potential merger if it was eventually presented to the board of directors for approval.

Representatives of Constellation and FPL Group (other than Messrs. Shattuck and Hay), together with their respective outside legal counsel and financial advisors, met in New York City on December 8 and 9, 2005 to review and negotiate the terms of the draft merger agreement (other than pricing) and of the governance matters in proposed Exhibit C. Substantial attention was devoted to the terms of the no solicitation covenants, termination fees and other provisions relating to a competing takeover proposal, as well as the conditions to closing, integration matters and the terms of the covenants that governed the operation of the two businesses between signing and closing. Following the resolution of a number of issues, it was agreed that the companies and their outside advisors would meet again in Baltimore along with Messrs. Shattuck and Hay on December 11, 2005 to seek to resolve the remaining open substantive issues.

On December 9, 2005, Messrs. Shattuck and Hay had numerous telephone conversations and discussed various open issues, including the issues being negotiated at the meetings in New York City on the same day. They also discussed various governance and compensation matters. In addition, Mr. Hay told Mr. Shattuck that it would be desirable for Mr. Shattuck to continue to remain employed by the combined company for a period of time following the closing of the merger, and they discussed various possible terms of such employment.

On December 9, 2005, the Constellation board of directors engaged Goldman Sachs to undertake a study to enable it to render its opinion as to the fairness of the exchange ratio contemplated by the potential merger agreement to the board of directors if the merger agreement was eventually presented to the board of directors for approval. The Constellation board of directors engaged Goldman Sachs to undertake this study to enable it to render such an opinion because of its qualifications, reputation and experience and because the Constellation board of directors believed Constellation and its stockholders would benefit from engaging Goldman Sachs in light of the extraordinary nature and significance of the proposed transaction to Constellation, the size and complexity of the merger and the recent trend of companies seeking the opinion of two financial advisors before approving a large, complex transaction.

On December 11, 2005, senior executives of Constellation and FPL Group and their respective outside legal counsel and financial advisors continued the negotiation of the merger agreement in Baltimore. The negotiations focused on the remaining open merger agreement issues other than price. The parties resolved various open issues involving the interim operating covenants, conditions to closing, no solicitation covenants, termination fees and other provisions relating to a competing takeover proposal, including that the termination fee for each company would equal approximately 4% of its market capitalization. They also agreed on various governance matters.

Throughout the week of December 12, 2005, the companies’ respective outside legal counsel exchanged and discussed several revised drafts of the merger agreement and Exhibit C. During that week, each company also distributed to the other initial drafts of its disclosure letter. The proposed forms of the amended and restated Constellation charter and by-laws also were prepared and negotiated and it was agreed that the Constellation board of directors would be declassified upon the completion of the merger.

On December 14, 2005, news reports were published regarding rumored negotiations between Constellation and FPL Group regarding a potential merger. The companies declined to comment on the rumors or the news reports.

From December 13 through 15, 2005, Messrs. Shattuck and Hay discussed economic terms in a series of telephone calls. Their respective financial advisors participated in several of these calls. The focus of the discussion was on a proposed ratio for Constellation’s pre-merger stock split. Over the course of these discussions, the parties narrowed the range between their positions. In a subsequent discussion between the

financial advisors on December 15, 2005, Merrill Lynch stated that FPL Group’s management was prepared to recommend a ratio of 1.44 to 1. Constellation’s financial advisors stated that Constellation’s management continued to believe that the companies should agree upon a higher ratio.

On December 14 and 15, 2005, Constellation’s Compensation Committee met with Mr. Shattuck, other members of the company’s legal and human resources staffs, the Committee’s outside compensation consultant and the Committee’s outside counsel to discuss Mr. Shattuck’s post-merger employment as the chairman of the combined company, as well as certain other severance, retention and other compensation matters. The Committee concluded that it was critical that Mr. Shattuck remain with the combined company for a period of time after a merger and as a result requested that he enter into an employment agreement pursuant to which Mr. Shattuck would continue with the combined company following the merger.

On December 15, 2005, at a regularly scheduled meeting, in addition to approving various matters relating to 2006 director and executive officer compensation, FPL Group’s Compensation Committee met to discuss severance and retention matters relating to the merger. Mr. Hay, members of the company’s human resources staff and representatives of the Committee’s outside compensation consultant, the Committee’s outside legal counsel for compensation matters and Cravath attended portions of this meeting. At the meeting, the Committee approved amendments to the executive severance retention agreements with FPL Group’s executives, an amendment to the employment agreement between FPL Group and Mr. Hay and the establishment of a retention program to assist in retaining employees of FPL Group through and after the merger.

On December 16, 2005, before the Constellation board of directors was scheduled to meet to discuss the proposed transaction and during a break in the meeting of the FPL Group board of directors (and prior to the beginning of the discussion of the proposed merger), Messrs. Shattuck and Hay and their financial advisors again discussed financial terms and Messrs. Shattuck and Hay agreed to recommend a pre-merger stock split ratio of 1.444-to-1 to their respective boards of directors. Representatives of Kirkland & Ellis and Cravath also negotiated and agreed to final changes to the provisions of the merger agreement that set forth the circumstances under which termination fees would become payable.

On December 16, 2005, the Constellation board of directors held a special meeting to consider the proposed merger. At the meeting, senior management updated the directors on the results of additional due diligence activities and merger agreement negotiations since the December 2, 2005 meeting. The board of directors discussed with management the business, operational and financial aspects of the proposed merger. Representatives of Kirkland & Ellis again reviewed with the board of directors their fiduciary obligations in the context of considering a proposed merger. They also reviewed with the board of directors in detail the terms of the then-current draft of the proposed merger agreement. They reported that all of the material terms had been negotiated and agreed. They also discussed with the board of directors the current drafts of the disclosure letters and the post-merger governance principles in Exhibit C. Representatives of Morgan Stanley and Goldman Sachs separately reviewed with the directors their financial analyses of the proposed merger. Each of them indicated that, based upon these analyses, they were each prepared to render an opinion to the Constellation board of directors that, based upon and subject to the assumptions, qualifications and limitations described by them and to be set forth in their written opinions, and assuming the prior effectiveness of the stock split, the exchange ratio of one share of Constellation common stock for each share of FPL Group common stock pursuant to the merger agreement was fair, from a financial point of view, to the Constellation stockholders. See “—Opinions of Constellation’s Financial Advisors” beginning on page 60.

Following these presentations, the Constellation board of directors meeting was recessed, and Constellation’s Compensation Committee met to discuss the proposed employment agreement with Mr. Shattuck, and certain additional matters. The Committee reviewed and discussed with its outside compensation consultant and its outside counsel for compensation matters information that had been prepared by management summarizing the level of compensation and other benefits that Mr. Shattuck would receive under existing plans and agreements in the event of a merger between the company and FPL Group, which would constitute a change

in control under Constellation’s plans and Constellation’s executive severance and retention agreements. The Committee reviewed a detailed employment agreement term sheet that had been revised and negotiated with Mr. Shattuck. The terms were consistent with those discussed by the Committee the prior day and members of the Committee reported on their discussions with Mr. Shattuck about the proposed terms. The Committee then approved the term sheet and authorized the Committee’s chairman and one of its other members to work with the Committee’s outside counsel to review a definitive agreement and for the Committee’s chairman to acknowledge such agreement, on behalf of the Committee, when it was finalized.

Following the completion of the Compensation Committee meeting, the board of directors reconvened in executive session (with only the non-executive directors present) to discuss the matters and information that the Compensation Committee reviewed and its decision regarding the terms of an employment agreement with Mr. Shattuck, as well as to continue its discussion of the proposed merger. Thereafter, Mr. Shattuck rejoined the other directors, and the board of directors continued to discuss the proposed merger. At the conclusion of the discussion, by unanimous vote of all of the directors present, the board of directors approved the merger agreement (subject to final negotiation to be completed by the company’s senior executives, in their discretion) and the merger, as well as the issuance of shares of Constellation common stock in connection with the merger and the proposed amendments to the Constellation charter and recommended that such matters be submitted for approval to the Constellation stockholders, as required.

On December 16, 2005, a regularly scheduled meeting of the FPL Group board of directors was held. At this meeting, members of FPL Group management made presentations to the FPL Group board of directors regarding, among other matters, an overview of the proposed merger and its key terms, the assignment of key management roles at a combined company, the principal reasons for the proposed merger and a due diligence and financial review of Constellation’s businesses and the proposed merger. Representatives of Merrill Lynch and Lehman Brothers made separate financial presentations regarding the proposed merger and indicated that they would be prepared to separately deliver to the FPL Group board of directors their respective opinions as to the fairness of the exchange ratio. See “—Opinions of FPL Group’s Financial Advisors” beginning on page 84. Representatives of Cravath reviewed for the FPL Group board of directors the fiduciary duties of the directors in connection with the consideration of the proposed merger. Representatives of Cravath also informed the board of directors that the material terms of the merger agreement had been fully negotiated and made a presentation of the terms and conditions of the draft merger agreement and other legal documents, focusing on the structure of the proposed transaction, the conditions to closing, post closing governance and related matters, the no solicitation covenants, the termination fees and other provisions relating to a competing takeover proposal. Representatives of Cravath also made a presentation regarding various compensation matters. The members of the FPL Group board of directors considered and discussed the various presentations made at the meeting. At this point, all the participants other than the members of the board of directors left the meeting and the meeting continued. Thereafter, Mr. Hay left the meeting and the non-executive directors met in executive session. Mr. Hay subsequently rejoined the other directors, and the FPL Group board of directors unanimously approved the proposed merger and the merger agreement (subject to final negotiation of the terms and conditions) and authorized FPL Group’s management to conclude negotiations and execute the merger agreement on the terms described to the FPL Group board of directors.

Following completion of the FPL Group board of directors meeting, Mr. Hay telephoned Mr. Shattuck, and they advised each other that their respective boards of directors had approved the proposed merger. They agreed to work out all final changes over the following two days with the objective of signing the definitive documents in time for a public announcement at 6:00 a.m. on Monday, December 19, 2005. Each of them advised their respective boards of directors, management teams and outside advisors of this.

On December 17 and 18, 2005, the companies and their outside legal counsel agreed upon all final revisions to all of the definitive documents. None of the revisions altered material terms of the merger agreement. During this time, the companies also negotiated various final changes to the permissible levels of acquisitions, dispositions, capital expenditures, share issuances and employee severance and retention payments that would be

permitted during the period from the execution of the merger agreement until the closing of the merger. In addition, there were several conference calls among Mr. Shattuck, members of Constellation’s Compensation Committee, representatives of Constellation’s outside legal counsel for compensation matters (Cleary Gottlieb Steen & Hamilton LLP), the Committee’s outside counsel for compensation matters, representatives of Kirkland & Ellis, and inside counsel of Constellation to discuss and finalize Mr. Shattuck’s employment agreement. In addition, inside counsel of Constellation and representatives of Cleary Gottlieb and Kirkland & Ellis had several telephone conversations with inside counsel of FPL and representatives of Cravath to discuss and finalize Mr. Shattuck’s employment agreement. Revised drafts of the employment agreement were distributed to and reviewed by all parties and additional comments were received and reflected.

On the evening of December 18, 2005, the companies’ outside legal counsel agreed to final changes to the disclosure letters, and the chairman and one other member of Constellation’s Compensation Committee, after conferring with its outside counsel and reviewing a proposed final draft of Mr. Shattuck’s employment agreement, approved and acknowledged the final form of that agreement. Thereafter, the companies executed the merger agreement and approved a joint press release for issuance the next morning to announce the execution of the merger agreement.

Constellation’s Reasons for the Merger; Recommendation of the Constellation Board of Directors

The Constellation board of directors has approved the merger agreement, has determined that the merger agreement and the transactions contemplated thereby, including the merger, the issuance of shares of Constellation common stock as contemplated by the merger agreement and the amendment and restatement of the Constellation charter, are advisable, fair to and in the best interests of Constellation and Constellation stockholders and recommends that Constellation stockholders vote FOR the proposal to approve the issuance of shares of Constellation common stock as contemplated by the merger agreement and the proposal to approve the amended and restated charter of Constellation.

In reaching its decision to recommend that the Constellation stockholders approve the issuance of shares of Constellation common stock as contemplated by the merger agreement and approve the amended and restated charter of Constellation, the Constellation board of directors consulted with Constellation management, as well as Morgan Stanley, Constellation’s financial advisor in connection with the merger, Goldman Sachs, an investment bank engaged to undertake a study to enable it to render its opinion to the Constellation board of directors with respect to the fairness from a financial point of view of the exchange ratio of one share of Constellation common stock for each share of FPL Group common stock, assuming the prior effectiveness of the stock split, and Kirkland & Ellis LLP, Constellation’s outside counsel, and considered various material factors described below. The following discussion of the information and factors considered by the Constellation board of directors is not intended to be exhaustive, but includes all material factors considered by the Constellation board of directors. In view of the wide variety of factors considered by the Constellation board of directors in connection with its evaluation of the merger, the Constellation board of directors did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. In considering the factors described below, individual members of the Constellation board of directors may have given different weight to different factors. The Constellation board of directors considered this information as a whole and overall considered the information and factors to be favorable to, and in support of, its determinations and recommendations. Among the material information and factors considered by the Constellation board of directors were the following:

Strategic Considerations. The Constellation board of directors considered a number of factors pertaining to the strategic rationale for the merger, including the following:

•

Improving the Balance of the Business. The combined company will have greater balance between regulated and unregulated businesses. Constellation expects that following the merger approximately half of the combined company’s earnings will come from its two utilities and approximately half will come from its competitive energy and other non-utility businesses. The larger and more stable financial

profile of the combined company should result in enhanced opportunities for growth, improved gross margins and greater operational and financing flexibility.

•

Expanding and Enhancing the Competitive Energy Business. The merger will create one of the leading competitive energy businesses by combining Constellation’s wholesale and retail competitive power supply business and generation portfolio with FPL Group’s leading and rapidly growing nuclear and renewable deregulated energy platform of nearly 12,500 megawatts of capacity. The transaction will increase the size of the generation assets of Constellation’s competitive energy business from approximately 12,000 megawatts to approximately 24,000 megawatts and create a more diverse portfolio of owned generation and purchased power across an increased portion of North America. The merger also will allow Constellation to apply the sophisticated hedging, portfolio management and risk management tools it has developed in its competitive energy business to a broader supply and customer base in the combined company’s competitive energy business.

•

Increasing the Diversity of the Business. The merger will allow Constellation to increase the diversification of its energy delivery and generation portfolio and its customer base. In the energy delivery business, the combined company will have two utility-based franchises with service areas encompassing more than 5.5 million people. These service areas also are located in dramatically different climates, which will diversify the impact of weather on the results of the utility operations. In addition, the combined company is expected to have approximately 45,000 megawatts of generation capacity in multiple states, with a fuel mix consisting of nuclear, coal, gas, oil, wind and other renewables. After the completion of the merger, Constellation will have the largest wind generation portfolio in the country. This generation portfolio diversification should create a more balanced portfolio in terms of geography, fuel mix, dispatch and load-servicing capacity.

•

Increasing the Strength of the Balance Sheet. The combined company will be one of the largest energy companies in North America and will rank first in terms of overall United States generation capacity and in wind generation in particular and third in nuclear generation capacity and will be the number one wholesale competitive supplier and retail competitive supplier in the United States, in each case in terms of megawatts. After the completion of the merger, Constellation will have approximately $57 billion in assets and substantial cash flow from operations. The strong balance sheet of the combined company will expand opportunities for productive, new capital deployments and support the growth of the competitive energy business.

•

Increasing the Capability and Opportunities for Growth. The merger will combine two fast-growing energy companies: Constellation, with its fast-growing competitive energy business, and FPL Group, with its fast-growing utility and unregulated renewable generation platforms. The expanded geographic footprint, increased generation assets and customer base and strong balance sheet of the combined company will provide Constellation with greater capability and opportunities to expand its business. The merger not only provides an opportunity for the combined company to capitalize on operating improvements and to share best practices, but also creates opportunities to expand the renewable and nuclear energy businesses.

•

Complementary Assets and Areas of Expertise. The merger will combine companies with complementary assets and areas of expertise: Constellation’s expertise in competitive energy supply and, more specifically, in the areas of hedging, portfolio management and risk management, and FPL Group’s deregulated generation capacity in certain markets (such as New England and Texas) where Constellation has a leading share of the competitive supply market but limited capacity and FPL Group’s expertise in wind energy and in managing a large, geographically dispersed transmission and energy delivery system. The combined company is expected to be able to draw upon the intellectual capital, technical expertise and experience of a deeper and more diverse workforce.

•

Improving the Regulated Businesses. The merger will allow Constellation to improve and strengthen the regulated businesses of both companies. These improvements will result from the strong balance sheet of the merged company, modest potential cost savings through leveraging utility expertise across a

broader platform and improving reliability through enhanced best practices. Florida Power & Light is the largest energy supplier in Florida, one of the fastest growing energy markets in North America.

•

Expanding and Improving Nuclear Operations. The combined company will have expanded nuclear operations which should enable the combined company to realize increased savings and efficiencies. The Constellation board of directors believes that the combined company’s nuclear operations will provide a strong platform to pursue continued nuclear consolidation and to potentially develop new nuclear plants.

Impact of the Merger on Customers, Employees and Suppliers. The Constellation board of directors evaluated the expected impact of the merger on Constellation’s customers, employees and suppliers and the benefits that would be derived from the merger by enhancing operations and strengthening reliability and by providing more opportunities for employees in a larger, more competitive company.

Impact of the Merger on Communities. The Constellation board of directors evaluated the expected impact of the merger on the communities served by Constellation and the benefits that would likely result to these communities from the greater strength of the merged company as compared to Constellation on a stand-alone basis and the likely improvements in the overall reliability and quality of service. The Constellation board of directors also considered that Constellation would maintain a headquarters in Baltimore, Maryland, that the merged company would continue to have substantial operations in Maryland and that the merged company would continue to be a significant benefactor of charities in the greater Baltimore and Maryland region.

Share Prices. The Constellation board of directors took note of the historic stock prices of Constellation and FPL Group and that the combination of the Constellation stock split and the exchange ratio in the merger reflected a 14.8% premium over the 20-day average closing price of Constellation common stock as of December 13, 2005, the last trading day prior to the first public reports of a possible transaction between Constellation and FPL Group.

Financial Considerations. The Constellation board of directors considered the expected financial impact of the merger on Constellation, including that the merger is expected to be accretive to stockholders of both companies after the first year, excluding transaction costs and the effects of purchase accounting, and that the accretive nature of the transaction would result in increased earnings per share of the combined company. The Constellation board of directors also considered the historic financial condition, operating results and businesses of Constellation and FPL Group, including information with respect to their respective earnings histories. The Constellation board of directors also considered that the merger was expected to result in an increased dividend for holders of Constellation common stock.

Opinions of Financial Advisors. The Constellation board of directors considered the financial analyses and presentations of each of Morgan Stanley and Goldman Sachs, as presented to the Constellation board of directors on December 16, 2005 (and subsequently confirmed in writing as of December 18, 2005) that as of that date and subject to and based upon the assumptions, qualifications and limitations discussed in each opinion, the exchange ratio pursuant to the merger agreement, assuming the prior effectiveness of the stock split, was fair, from a financial point of view, to the holders of Constellation common stock. See “—Opinions of Constellation’s Financial Advisors” beginning on page 60.

Strategic Alternatives. The Constellation board of directors considered the trends and competitive developments in the industry and the range of strategic alternatives available to Constellation, including the possibility of business combinations with other participants in the industry or continuing to operate as a stand-alone entity. In particular, the Constellation board of directors considered various alternative strategies by which Constellation could achieve the goal of greater balance within its businesses as discussed above. These alternative strategies included continuing as a stand-alone company and, based on prior periodic discussions with other companies about potential business combinations, the possibility of business combination transactions with third parties. The Constellation board of directors concluded that Constellation’s ability to expand its

opportunities for new capital deployments and support the growth of its competitive energy business would be enhanced by the balance sheet of the combined company that would result from the proposed merger with FPL Group. At the time of its consideration of the merger, Constellation was not involved in discussions regarding any other business combination transaction. The Constellation board of directors determined that the merger was more favorable to Constellation and its stockholders than other possible strategic alternatives known to Constellation at that time.

Recommendation of Management. The Constellation board of directors took into account management’s recommendation in favor of the merger.

Terms of the Merger Agreement. The Constellation board of directors reviewed and considered the terms of the merger agreement, including the fixed nature of the exchange ratio, the restrictions on each party’s operations between the signing of the merger agreement and the closing of the transaction, the representations and warranties of each party, the conditions to each party’s obligation to complete the merger, the rights of each party to consider and engage in negotiations regarding potentially superior proposals, the rights of each party to withdraw or otherwise change its recommendation to its stockholders in favor of the proposals related to the merger agreement, the rights of each party to terminate the merger agreement and the obligations of each party to pay a termination fee or reimburse the other party for expenses. See “The Merger Agreement” beginning on page 132 for a detailed discussion of the terms and conditions of the merger agreement.

Due Diligence. The Constellation board of directors considered the scope of the due diligence investigation of FPL Group conducted by Constellation management and Constellation’s outside advisors and evaluated the results thereof.

Synergies. The Constellation board of directors considered that, although no assurance can be given that any particular level of cost savings and other synergies will be achieved, Constellation and FPL Group management had identified estimated synergies of approximately $200 million to $250 million that could be realized by the end of the third full year of operations following completion of the merger. A substantial majority of these synergies are expected to come from the competitive energy business. These cost savings are expected to result from consolidation of competitive energy business unit operations, improved procurement strategies (including from increased purchasing leverage) and consolidation of information systems and corporate overhead/support activities (including from a consolidated staff and transaction processing support). Constellation management estimated that approximately one-third of these synergies would be realized in each of the three years following completion of the merger, prior to the payment of out-of-pocket expenses, taxes and transaction costs. The Constellation board of directors took note of the fact that the synergy numbers were estimates, that they may change and that achieving the synergies is subject to a number of uncertainties. In addition, Constellation management did not compare the estimated synergies related to the merger to synergies of other potential transactions because Constellation was not actively considering any other potential business combination transaction at the relevant time. See “The Introduction—Risk Factors—Risks Relating to the Merger” beginning on page 22.

Likelihood of Completion of the Merger. The Constellation board of directors considered the likelihood that the merger will be completed on a timely basis, including the likelihood that the merger will receive all necessary regulatory approvals without unacceptable conditions. The Constellation board of directors took note of the closing condition in the merger agreement that neither Constellation nor FPL Group is required to complete the merger if any governmental authority were to impose terms or conditions in connection with the required statutory approvals that would reasonably be expected to have a material adverse effect and materially decrease the long-term value of either party (or the merged company). The Constellation board of directors further considered the potential length of the regulatory approval process and that the merger agreement provides that, subject to certain exceptions, it may not be terminated until December 31, 2006, which may be extended to June 30, 2007 under specified circumstances.

Post-Merger Corporate Governance. The Constellation board of directors considered the corporate governance provisions of the merger agreement and the amended and restated charter and amended and restated by-laws of Constellation to be adopted upon completion of the merger, including that, upon completion of the merger, the Constellation board of directors will be comprised of six persons who served as Constellation directors prior to the merger and nine persons who served as FPL Group directors prior to the merger, that Mr. Mayo A. Shattuck III will serve as Chairman of the Board of Directors of the combined company and Mr. Lewis Hay, III, the current Chairman, President and Chief Executive Officer of FPL Group, will serve as the Chief Executive Officer of the combined company. The Constellation board of directors also considered the terms of Mr. Shattuck’s employment agreement. See “—Post-Merger Governance and Management” beginning on page 145 for further information.

The Constellation board of directors also considered potential risks associated with the merger, including the following:

FPL Group Business Risks. The Constellation board of directors considered certain risks associated with FPL Group’s business and operations, including the impact of hurricanes on FPL Group’s regulated utility business and on the regulatory and legislative environment in Florida, limits on the ability of Florida Power & Light to obtain insurance coverage for storm damage and FPL Group’s various contingent liabilities. It was noted that storm restoration costs incurred by FPL Group’s regulated utility business would not affect the distribution rates charged by Constellation’s regulated utility business.

Termination Fee; Alternative Proposals. The Constellation board of directors considered the risk that, although Constellation has the right under certain limited circumstances to consider and participate in negotiations with respect to proposals for alternative transactions, the provisions of the merger agreement relating to the potential payment of a termination fee of $425 million may have the effect of discouraging such proposals. In addition, the Constellation board of directors considered that, under specified circumstances related to the presence of an alternative proposal, Constellation would be required to pay FPL Group a fee of $100 million or reimburse FPL Group for its out-of-pocket expenses, although in no event would the aggregate amount payable by Constellation to FPL Group exceed $425 million, which payment obligations also could have the effect of discouraging alternative proposals. The merger agreement also includes other customary restrictions on the ability of Constellation to solicit offers for alternative proposals or engage in discussions regarding such proposals, subject to exceptions, which could have the effect of discouraging such proposals from being made or pursued. The Constellation board of directors understood that these provisions may have the effect of discouraging alternative proposals and may make it less likely that the transactions related to such proposals would be negotiated or pursued, even if potentially more favorable to the stockholders of Constellation than the merger. See “—The Merger Agreement—Termination of Merger Agreement—Termination Fees/Reimbursement of Expenses Payable by Constellation” beginning on page 143 for further information regarding such fees and expenses.

Employee Matters. The Constellation board of directors considered the impact that business uncertainty pending completion of the merger could have on the ability to attract, retain and motivate key personnel until the merger is completed. The Constellation board of directors also considered the terms of Constellation’s various employee benefit plans and agreements that would entitle executive officers and employees to receive payments and other benefits upon completion of the merger and took account of the costs of such plans and agreements and the potential impact they might have on retention of executives and key employees following the merger.

Additional Interests of Executive Officers and Directors. The Constellation board of directors considered that certain executive officers and directors of Constellation may have interests with respect to the merger in addition to their interests as stockholders of Constellation. See “—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger” beginning on page 113 for further information.

Fixed Exchange Ratio. The Constellation board of directors considered that neither the ratio for the stock split nor the one-for-one exchange ratio that FPL Group shareholders will receive pursuant to the merger will adjust to compensate for changes in the price of Constellation common stock or FPL Group common stock prior to the closing of the merger.

Restrictions on Interim Operations. The Constellation board of directors considered the provisions of the merger agreement placing restrictions on Constellation’s operations during the period between the signing of the merger agreement and the completion of the merger.

Diversion of Management. The Constellation board of directors considered the possible diversion of management’s time and attention from Constellation’s ongoing business due to the substantial time and effort necessary to complete the merger and plan for and implement the integration of the operations of Constellation and FPL Group.

The Constellation board of directors believed that, overall, the potential benefits of the merger to Constellation and its stockholders outweighed the risks.

The Constellation board of directors realized that there can be no assurance about future results, including results considered or expected as described in the factors listed above, such as assumptions regarding potential synergies. It should be noted that this explanation of the Constellation board of directors’ reasoning and all other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Note Regarding Forward-Looking Statements” beginning on page 34.

Opinions of Constellation’s Financial Advisors

Each of Morgan Stanley and Goldman Sachs rendered its oral opinion to the Constellation board of directors (subsequently confirmed in writing as of December 18, 2005) that as of such date and based upon and subject to the assumptions, qualifications and limitations discussed in its written opinion, assuming the prior effectiveness of the stock split, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to holders of Constellation common stock.

The full text of the opinions of Morgan Stanley and Goldman Sachs, each dated December 18, 2005, which discuss, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations of the reviews undertaken by each of Morgan Stanley and Goldman Sachs in rendering their respective opinions, are attached as Annex B and Annex C, respectively, to this joint proxy statement/prospectus and are incorporated into this joint proxy statement/prospectus by reference. The summary of each of the Morgan Stanley and Goldman Sachs fairness opinions provided in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of each of the opinions. Constellation stockholders are urged to read these opinions carefully and in their entirety. Each of the Morgan Stanley and Goldman Sachs opinions is addressed to the Constellation board of directors and is directed only to the fairness, from a financial point of view, assuming the prior effectiveness of the stock split, of the exchange ratio pursuant to the merger agreement. Neither the Morgan Stanley nor Goldman Sachs opinion constitutes a recommendation to any Constellation stockholder as to how any such stockholder should vote with respect to the proposed merger or any other matter. The opinions also do not address the prices at which shares of Constellation common stock will trade following the completion of the merger or at any other time.

Opinion of Morgan Stanley & Co. Incorporated

In connection with rendering its opinion, Morgan Stanley, among other things:

reviewed certain publicly-available financial statements and other business and financial information of Constellation and FPL Group, respectively;

xi)

participated in discussions and negotiations among representatives of Constellation and FPL Group and their financial and legal advisors;

xii)

xiii)

considered such other factors and performed such other analyses as it deemed appropriate.

In arriving at its opinion, Morgan Stanley assumed and relied upon without independent verification the accuracy and completeness of the information supplied or otherwise made available to it by Constellation and FPL Group for the purposes of its opinion. With respect to the financial projections, including information relating to certain strategic, financial and operational benefits anticipated from the merger, Morgan Stanley assumed that they were reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of Constellation and FPL Group. Morgan Stanley also relied on the assessments of senior management of Constellation and FPL Group of the strategic rationale for the merger. Morgan Stanley assumed that the stock split would occur on the terms set forth in the merger agreement, including, among other things, the timing thereof. In addition, Morgan Stanley assumed that the merger and the other transactions contemplated in the merger agreement would be completed in accordance with the terms set forth in the merger agreement, including, among other things, that the merger would be treated as a tax-free reorganization, pursuant to the Internal Revenue Code of 1986, as amended. Morgan Stanley assumed that, in connection with the receipt of all necessary regulatory approvals for the proposed merger, no restrictions would be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed merger. Morgan Stanley did not make any independent valuation or appraisal of the assets or liabilities of Constellation or of FPL Group, nor was Morgan Stanley furnished with any such appraisals. Morgan Stanley is not a legal, regulatory or tax expert and relied upon the assessments of Constellation, after receiving advice from its other advisors, with respect to such issues. Morgan Stanley’s opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Morgan Stanley as of, December 18, 2005.

In arriving at its opinion, Morgan Stanley was not authorized to solicit, and did not solicit, interest from any party with respect to an acquisition or business combination involving Constellation or any of its assets.

The following is a summary of the material financial analyses performed by Morgan Stanley in connection with the delivery of its oral opinion on December 16, 2005, which was subsequently confirmed in writing on December 18, 2005. Although each analysis was provided to the Constellation board of directors, in connection with arriving at its opinion, Morgan Stanley considered all of its analysis as a whole and did not attribute any particular weight to any analysis described below. Some of these summaries include information in tabular format. In order to understand fully the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the analyses.

For purposes of its analysis, Morgan Stanley noted that the stock split would occur immediately prior to the effectiveness of the merger, and as a result the effective exchange ratio for Constellation stockholders would be 1.444 shares of common stock of the combined company for each share of existing Constellation common stock.

Historical Trading and Exchange Ratio Analysis. Morgan Stanley performed a historical trading and exchange ratio analysis to obtain background information and perspective with respect to the relative historical share prices of Constellation common stock and FPL Group common stock. Morgan Stanley reviewed the historical price performance of Constellation common stock and FPL Group common stock for various periods ending on December 13, 2005.

Morgan Stanley noted that for the 52-week period ending December 13, 2005, which was the last trading day prior to reports appearing in the press regarding a potential merger, the closing prices per share of Constellation common stock ranged from $42.45 to $62.60 and for FPL Group common stock ranged from $35.90 to $48.11.

The following table displays the historical trading ratio of Constellation common stock and FPL common stock over various periods. The following analysis was performed to provide perspective on the historical trading ratio versus the exchange ratio for the proposed merger.


Period Ending December 13, 2005	Average Constellation Price Per Share		Average FPL Group Price Per Share		Historical Trading Ratio
20 Trading Days Prior	$	53.44	$	42.39	1.26	x
3 Months Prior	$	55.42	$	43.63	1.27	x
6 Months Prior	$	56.74	$	43.16	1.31	x
12 Months Prior	$	53.50	$	41.33	1.29	x
3 Years Prior	$	41.83	$	35.14	1.19	x

Morgan Stanley noted that the effective exchange ratio was 1.444x, resulting in an implied consideration to Constellation stockholders of $61.90 per share, based on a closing price of FPL Group common stock of $42.87 as of December 13, 2005.

Comparable Public Companies Analysis. Morgan Stanley performed a comparable company analysis, which attempts to provide an implied value for Constellation and FPL Group by comparing them to similar companies. For purposes of its analysis, Morgan Stanley reviewed and compared certain publicly available and internal financial information, ratios and publicly available market multiples relating to Constellation and FPL Group to corresponding financial data for publicly-traded utility companies that shared characteristics with Constellation and FPL Group.

The companies included in the Constellation comparable companies analysis were:

•

Entergy Corporation

•

Exelon Corporation

•

PPL Corporation

•

Sempra Energy

•

TXU Corporation

The companies included in the FPL Group comparable companies analysis were:

•

Dominion Resources, Inc.

•

Entergy Corporation

•

Exelon Corporation

•

Progress Energy, Inc.

Morgan Stanley then reviewed both publicly available and internal Constellation financial information to compare financial information and multiples of market value of the companies included in the Constellation comparable companies analysis to the following Constellation metrics based on publicly available and internal financial information:

•

the price per share to 2006 estimated earnings per share (which we refer to herein as EPS);

•

the price per share to 2007 estimated EPS; and

•

Aggregate Value (defined as equity value plus estimated non-convertible debt, minority interest, capital lease obligations and preferred stock less cash and cash equivalents as of September 30, 2005) divided by estimated 2006 earnings before interest, taxes, depreciation and amortization, or EBITDA.

The following table reflects the results of this analysis, as compared to the multiples for Constellation based on average statistics of earnings and EBITDA estimates for these companies obtained from I/B/E/S, a data service that monitors and publishes a compilation of earnings estimates produced by selected research analysts on companies of interest to investors:


	Price to EPS				Aggregate Value to EBITDA
	2006E		2007E		2006E
Representative range derived from
Constellation comparables	12.5x – 15.0	x	10.5x – 13.0	x	7.0x – 8.0	x
Constellation multiples	14.6	x	11.6	x	7.3	x

As part of its comparable company analysis, Morgan Stanley applied a representative range of multiples derived from the comparable public companies analysis. Based upon and subject to the foregoing, Morgan Stanley calculated a range of implied equity values per share of Constellation common stock based on Constellation’s projected financial results with respect to the following Constellation metrics:

•

the price per share to 2006 estimated earnings per share (which we refer to herein as EPS);

•

the price per share to 2007 estimated EPS; and

•

Aggregate Value divided by estimated 2006 EBITDA.

Based on this analysis, Morgan Stanley derived a range of implied equity values per share of Constellation common stock of $44.51 to $64.63. Morgan Stanley noted that the effective exchange ratio was 1.444x, resulting in an implied consideration to Constellation of $61.90 per share, based on a closing price of FPL Group common stock of $42.87 as of December 13, 2005.

Morgan Stanley then reviewed publicly available financial information to compare financial information and multiples of market value of the companies included in the FPL Group comparable companies analysis to FPL Group’s publicly available and internal financial information:

•

the price per share to 2006 estimated EPS;

•

the price per share to 2007 estimated EPS; and

•

Aggregate Value divided by estimated 2006 EBITDA.

The following table reflects the results of the analysis, as compared to the multiples for FPL Group based on representative ranges of median I/B/E/S earnings and EBITDA forecasts:


	Price to EPS				Aggregate Value to EBITDA
	2006E		2007E		2006E
Representative range derived from
FPL Group comparables	14.0x – 16.0	x	12.0x – 14.0	x	7.5x – 8.5	x
FPL Group multiples	15.3	x	13.5	x	8.0	x

Applying a range of multiples derived from the comparable public companies analysis, Morgan Stanley calculated a range of implied equity values per share of FPL Group common stock based on average statistics of earnings and EBITDA estimates obtained from I/B/E/S with respect to FPL Group:

•

the price per share to 2006 estimated EPS;

•

the price per share to 2007 estimated EPS; and

•

Aggregate Value divided by estimated 2006 EBITDA.

Based on this analysis, Morgan Stanley derived a range of implied equity values per share of FPL Group common stock of $36.72 to $45.00. Morgan Stanley noted that the closing price of FPL Group common stock on December 13, 2005 was $42.87.

Although the comparable companies in this analysis were compared to Constellation and FPL Group for purposes of this analysis, no company utilized in this analysis is identical to Constellation or FPL Group. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial and operating characteristics of Constellation and FPL Group and other factors that could affect the public trading value of the companies to which they are being compared. In evaluating the comparable companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Constellation or FPL Group, such as the impact of competition on Constellation or FPL Group and the industry generally, industry growth and the absence of any adverse material change in the financial conditions and prospects of Constellation or FPL Group or the industry or in the financial markets in general. Mathematical analysis, such as determining the mean, median or average, is not in itself a meaningful method of using comparable company data.

Discounted Cash Flow Analyses. Morgan Stanley also performed a discounted cash flow analysis based on consolidated financial projections provided by the management of Constellation for the period from January 1, 2006 through December 31, 2008 and the management of FPL Group for the period from January 1, 2006 through December 31, 2008. This type of analysis is designed to provide insight into the value of a company as a function of its future cash flows and expenditures. Unlevered free cash flows were calculated as net income available to common stockholders plus the aggregate of depreciation and amortization, deferred taxes, and other noncash expenses and after-tax net interest expense less the sum of capital expenditures and investment in noncash working capital.

For the Constellation discounted cash flow analysis, Morgan Stanley calculated a range of terminal values at the end of the projection period by applying a multiple to Constellation’s projected 2008 EBITDA provided by Constellation’s management and to publicly available Morgan Stanley equity research projected 2008 EBITDA. The Aggregate Value to EBITDA multiple range used in each case was 6.5x to 7.5x. The free cash flows and range of terminal values were then discounted to present values using a range of discount rates which were chosen by Morgan Stanley based upon analysis of market discount rates applicable to comparable companies. The weighted average cost of capital range used in each case was 6.5% to 7.5%. From this analysis, Morgan Stanley calculated a range of equity values per share of Constellation common stock as of December 13, 2005 of $45.06 to $66.79. Morgan Stanley noted that the effective exchange ratio was 1.444x, resulting in an implied consideration to Constellation of $61.90 per share, based on a closing price of FPL Group common stock of $42.87 as of December 13, 2005.

For the FPL Group discounted cash flow analysis, Morgan Stanley calculated a range of terminal values at the end of the projection period by applying a multiple to FPL Group’s projected 2008 EBITDA. The Aggregate Value to EBITDA multiple range used was 7.0x to 8.0x. The free cash flows and range of terminal values were then discounted to present values using a range of discount rates which were chosen by Morgan Stanley based upon analysis of market discount rates applicable to comparable companies. The weighted average cost of capital range used was 6.0% to 7.0%. From this analysis, Morgan Stanley calculated a range of equity value per share of

FPL Group common stock as of December 13, 2005 of $36.30 to $46.41. Morgan Stanley noted that the closing price of FPL Group common stock on December 13, 2005 was $42.87.

Sum-of-Parts Comparable Public Companies Analysis. Using Constellation management estimates, Morgan Stanley compared certain publicly available financial measures of selected comparable companies to those of the relevant businesses within Constellation in order to derive an implied value for Constellation based on the sum value of its various businesses. Morgan Stanley selected these comparable companies based upon its views as to the comparability of the financial and operating characteristics of these companies to the relevant Constellation businesses. Morgan Stanley calculated reference value ranges for the Constellation businesses by applying various multiples derived from these comparable companies to selected financial measures of the relevant Constellation businesses based on information provided by Constellation’s management. With respect to Constellation’s synthetic fuel assets, Morgan Stanley conducted a separate discounted cash flow analysis covering the entire period during which Constellation’s synthetic fuel assets were projected to provide cash flow; therefore, a comparable public companies multiple based approach was not used for this business. Based on this analysis, Morgan Stanley calculated per share values for Constellation common stock ranging from $48.60 to $57.18. Morgan Stanley noted that the effective exchange ratio was 1.444x, resulting in an implied consideration to Constellation of $61.90 per share based on a closing price of FPL Group common stock of $42.87 as of December 13, 2005.

Analysis of Selected Precedent Transactions. Morgan Stanley reviewed selected precedent transactions in order to develop implied valuation ranges for the Constellation common stock. Using publicly available information, Morgan Stanley considered the following 6 announced or completed transactions:

•

PacifiCorp Holdings, Inc. / MidAmerican Energy Holdings Company, announced May 24, 2005

•

Cinergy Corp. / Duke Energy Corporation, announced May 9, 2005

•

Public Service Enterprise Group Incorporated (“PSEG”) / Exelon Corporation, announced December 20, 2004

•

UniSource Energy Corporation / Kohlberg Kravis Roberts & Co., announced November 24, 2003

•

Portland General Electric Company / Texas Pacific Group & Oregon Electric Utility Company, LLC, announced November 18, 2003

•

Connectiv / Potomac Electric Power Company (“PEPCO”), announced February 12, 2001

Morgan Stanley considered certain financial and market statistics of the selected precedent transactions, including stock price to earnings multiples, Aggregate Value to EBITDA multiples and premium to unaffected market prices. Based on an assessment of stock price to earnings multiples of the selected precedent transactions, Morgan Stanley applied a multiple to Constellation’s 2005 estimated earnings ranging from 15.0x – 17.0x and a multiple to Constellation’s 2006 estimated earnings ranging from 14.0x – 16.0x, which results in per share values for Constellation common stock ranging from $48.96 to $62.90. Based on an assessment of Aggregate Value to EBITDA multiples of the selected precedent transactions, Morgan Stanley applied a multiple to Constellation’s 2005E EBITDA ranging from 8.5x – 10.0x, which results in per share values for Constellation common stock ranging from $57.40 to $71.26. Based on an assessment of premium to unaffected market prices, Morgan Stanley applied a premium to Constellation’s December 13, 2005 market price ranging from 13% to 19% and a premium to Constellation’s average market price for the 20 days ending December 13, 2005 ranging from 13% to 19%, which results in per share values for Constellation common stock ranging from $60.39 to $66.96. Morgan Stanley noted that the effective exchange ratio was 1.444x, resulting in an implied consideration to Constellation of $61.90 per share based on a closing price of FPL Group common stock of $42.87 as of December 13, 2005.

No transaction utilized as a comparison in the analysis of selected precedent transactions is identical to the merger in business mix, timing and size. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial and operating characteristics

of Constellation and other factors that would affect the value of the companies to which it is being compared. In evaluating the precedent transactions, Morgan Stanley made judgments and assumptions with regard to industry performance, global business, economic, market and financial conditions and other matters, many of which are beyond the control of Constellation, such as the impact of competition on Constellation and the industry generally, industry growth and the absence of any adverse material change in the financial conditions and prospects of Constellation or the industry or the financial markets in general. Mathematical analysis (such as determining the mean or median) is not, in itself, a meaningful method of using precedent transactions data.

Pro Forma Transaction Analysis. Using financial projections provided by Constellation’s and FPL Group’s managements, Morgan Stanley reviewed the pro forma impact of the merger on Constellation’s and FPL Group’s estimated EPS for the years 2006-2008. For purposes of this analysis, Morgan Stanley assumed the transaction closed on January 1, 2006.

Using each company’s forward-looking financial information as the basis of comparison, the pro forma impact on earnings per share, taking into account all projected merger-related adjustments, including certain purchase accounting adjustments and Constellation’s estimates of expected synergies, was found to be accretive to earnings from 2006 to 2008 for Constellation and accretive to earnings from 2006 to 2008 for FPL Group.

Using each company’s forward-looking financial information as the basis of comparison, the pro forma impact on earnings per share, taking into account all projected merger- related adjustments (including Constellation’s estimates of expected synergies) except for certain purchase accounting adjustments, was found to be accretive to earnings from 2006 to 2008 for Constellation and accretive to earnings from 2006 to 2008 for FPL Group.

Contribution Analysis. Morgan Stanley reviewed the pro forma effect of the merger and computed the implied equity contribution of Constellation and FPL Group for the years ended December 31, 2006 and December 31, 2007. Such financial results included EBITDA, EBIT and net income provided by the management of FPL and Constellation. The computation showed, among other things, that Constellation’s implied equity contribution based on 2006 and 2007 projected EBITDA was 38% and 42%, respectively; Constellation’s implied equity contribution based on 2006 and 2007 projected EBIT was 40% and 45%, respectively; and Constellation’s implied equity contribution based on 2006 and 2007 net income was 39% and 41%, respectively. Morgan Stanley noted that the effective exchange ratio was 1.444x, which would result in a proforma ownership of the combined company for holders of Constellation common stock equal to approximately 40%.

In connection with the review of the transaction with the Constellation board of directors, Morgan Stanley performed a variety of financial and comparable analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not susceptible to partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered. Furthermore, Morgan Stanley believes that the summary provided and the analyses described above must be considered as a whole and that selecting any portion of the analyses, without considering all of them, would create an incomplete view of the process underlying Morgan Stanley’s analyses and opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above should not be taken to be the view of Morgan Stanley with respect to the actual value of Constellation common stock or FPL Group common stock.

In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Constellation or FPL Group. Any estimates contained in Morgan Stanley’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by the estimates. The analyses performed were performed solely as part of Morgan Stanley’s analysis of the fairness from a financial point of view of the exchange ratio pursuant to the merger agreement and assuming the prior effectiveness of the stock split, and were conducted in connection with the delivery of Morgan Stanley’s opinion dated December 18,

2005 to the Constellation board of directors. The analyses do not purport to be appraisals or to reflect the prices at which Constellation common stock or FPL Group common stock might actually trade. The stock split applicable to each share of Constellation common stock and the exchange ratio under the merger agreement and other terms of the merger agreement were determined through arm’s length negotiations between Constellation and FPL Group and approved by the Constellation board of directors. The opinion of Morgan Stanley was one of a number of factors taken into consideration by the Constellation board of directors in making its decision to approve the merger agreement and the transactions contemplated by the merger agreement. Consequently, Morgan Stanley’s analyses described above should not be viewed as determinative of the opinion of the Constellation board of directors with respect to the value of Constellation or FPL Group. See “—Constellation’s Reasons for the Merger; Recommendation of the Constellation Board of Directors” beginning on page 55.

Morgan Stanley, as part of its investment banking businesses, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Constellation selected Morgan Stanley as its financial advisor based upon the firm’s qualifications, experience and expertise and because it is an internationally recognized investment banking firm with substantial experience in transactions similar to the merger. In the ordinary course of its trading and brokerage activities, Morgan Stanley and its affiliates may at any time hold long or short positions, trade or otherwise effect transactions, for their own accounts or for the accounts of customers, in the equity or debt securities or senior loans of Constellation or FPL Group or any currency or commodity related to Constellation or FPL Group. Pursuant to the terms of its engagement, Constellation has agreed to pay Morgan Stanley a fee of $22,000,000 payable according to the following schedule: (a) 25% of the fee payable upon the execution of the merger agreement, (b) 25% of the fee payable upon approval of the merger proposals by the Constellation stockholders, and (c) the remainder of the fee payable upon the completion of the merger. Constellation has also agreed to reimburse Morgan Stanley for its fees and expenses incurred in performing its services. In addition, Constellation has agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities under the federal securities laws, related to or arising out of Morgan Stanley’s engagement and any related transactions. In the past, Morgan Stanley and its affiliates have provided financial advisory and financing services for Constellation and FPL Group and have received fees for the rendering of these services. In addition, Morgan Stanley is a participant in various revolving credit facilities of Constellation and FPL Group. Morgan Stanley also may or may in the future seek to provide financial advice or financing services to Constellation and FPL Group and may receive fees for such services.

Opinion of Goldman, Sachs & Co.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

•

the merger agreement;

•

annual reports to stockholders and Annual Reports on Form 10-K of Constellation and FPL Group for the five fiscal years ended December 31, 2004;

•

certain interim reports to stockholders and Quarterly Reports on Form 10-Q of Constellation and FPL Group;

•

certain other communications from Constellation and FPL Group to their respective stockholders;

•

certain internal financial analyses and forecasts for FPL Group prepared by the management of FPL Group; and

•

certain internal financial analyses and forecasts for Constellation and for FPL Group delivered by the management of Constellation, which are collectively referred to as the Forecasts, including certain cost savings and operating synergies projected by the managements of Constellation and FPL Group to result from the merger.

Goldman Sachs also held discussions with members of the senior management of Constellation and FPL Group regarding their assessment of the strategic rationale for, and the potential benefits of, the merger and the past and current business operations, financial condition and future prospects of their respective companies. In addition, Goldman Sachs reviewed the reported price and trading activity for the Constellation common stock and the FPL Group common stock, compared certain financial and stock market information for Constellation and FPL Group with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the utilities industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as it considered appropriate.

Goldman Sachs relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of rendering the opinion described above. In that regard, Goldman Sachs assumed with the consent of Constellation that the Forecasts were reasonably prepared on a basis reflecting the best currently available estimates and judgments of Constellation and FPL Group, as the case may be. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of Constellation or FPL Group or any of their respective subsidiaries and Goldman Sachs was not furnished with any such evaluation or appraisal. Goldman Sachs also assumed that all governmental, regulatory or other consents and approvals necessary for the completion of the merger will be obtained without any adverse effect on Constellation or FPL Group or on the expected benefits of the merger in any way meaningful to Goldman Sachs’ analysis.

The following is a summary of the material financial analyses presented by Goldman Sachs to the Constellation board of directors in connection with rendering the opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs. The order of analyses described does not represent the relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tables. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs’ financial analyses. The following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before December 13, 2005 (the last trading day prior to published press reports regarding the potential merger), except for the closing share price data referred to in the first bullet of the Transaction Premium Analysis below, which is as of December 15, 2005, and is not necessarily indicative of current market conditions.

While the merger agreement provides that each share of FPL Group common stock will be converted into the right to receive one share of Constellation common stock, subject to the prior effectiveness of a 1.444-for-1 split of the Constellation common stock, for purpose of its analyses, Goldman Sachs considered the exchange ratio, after giving effect to the stock split, to be the economic equivalent of an implied exchange ratio of 1.444 shares of FPL Group common stock for each share of Constellation common stock.

Transaction Premium Analysis

Using various closing and average closing prices per share of FPL Group common stock, Goldman Sachs calculated the implied value (based on such prices) of the 1.444 shares of FPL Group common stock deemed to be exchanged for each share of Constellation common stock and then compared that implied value to prices per share of Constellation common stock for the same dates and periods listed below.

Goldman Sachs also calculated the amount by which the implied value of the implied exchange ratio exceeded the prices per share of Constellation common stock listed below. The amount by which the implied value of the implied exchange ratio exceeded the prices per share of Constellation common stock listed below is referred to as a premium and is expressed as a percentage.

The FPL Group and Constellation stock prices used by Goldman Sachs, along with the results of their analysis, is set forth below:


	FPL Group Share Price		Implied Constellation Share Price Based on Implied 1.444 Exchange Ratio and then current FPL Group Stock Price		Constellation Share Price		Implied Premium Based on Implied 1.444 Exchange Ratio and then current FPL Group Stock Price:
As of December 15, 2005	$	42.54	$	61.43	$	61.09	1	%
As of December 13, 2005	$	42.87	$	61.90	$	56.27	10	%

52-Week Low	$	36.03	$	52.03	$	43.08	21	%

Historical Exchange Ratio Analysis

Goldman Sachs divided the price per share of the Constellation common stock as of, or for, the time periods listed below by the price per share of the FPL Group common stock as of, or for, the same periods in order to determine an implied exchange ratio. The following table reflects the results of this analysis:


Period:	Implied Exchange Ratio:
1 Day Prior to December 13, 2005	1.31	x
5 Days Prior to December 13, 2005	1.26	x
10 Days Prior to December 13, 2005	1.25	x
15 Days Prior to December 13, 2005	1.24	x
20 Days Prior to December 13, 2005	1.26	x
25 Days Prior to December 13, 2005	1.27	x
30 Days Prior to December 13, 2005	1.28	x
3 Month Average, ending December 13, 2005	1.27	x
6 Month Average, ending December 13, 2005	1.32	x
1 Year Average, ending December 13, 2005	1.29	x
3 Year Average, ending December 13, 2005	1.18	x
5 Year Average, ending December 13, 2005	1.15	x

The exchange ratio implied by the merger agreement, assuming the prior effectiveness a 1.444 – for – 1 split of the Constellation common stock, is 1.444x.

Contribution Analysis

Using projections of the future results of Constellation and FPL Group delivered to Goldman Sachs by the management of Constellation, Goldman Sachs analyzed how much each of Constellation and FPL Group would contribute to the combined company with respect to the following financial measures:

•

gross margin

•

earnings before interest, taxes, depreciation and amortization, which we refer to as EBITDA;

•

earnings before interest and taxes, which we refer to as EBIT; and

•

net income.

For the calendar years 2005 through 2008, Goldman Sachs calculated the total amount of each financial measure listed above that the combined company would have by adding together the amounts forecasted for each of FPL Group and Constellation. Goldman Sachs then calculated how much each of FPL Group and Constellation contributed to that total, expressed as a percentage.

Goldman Sachs then calculated how much each company would contribute to the implied equity value of the combined company based on enterprise values calculated using the financial measures listed above. Enterprise value is generally defined as the value of a company’s equity, plus the aggregate amount of its indebtedness less the amount of its cash and plus any minority interest. Goldman Sachs calculated enterprise value for each company by applying enterprise value multiples to each company’s projected gross margin, EBITDA and EBIT for the calendar years 2005 through 2008. Goldman Sachs then subtracted the amount of each company’s net debt (meaning indebtedness less cash) and minority interest to arrive at an implied equity value. Goldman Sachs then added together the implied equity values for Constellation and FPL Group to derive an implied equity value for the combined company and also calculated how much each company contributed to that implied equity value, which is expressed as a percentage.

Goldman Sachs performed this analysis using two sets of enterprise value multiples:

•

Weighted average multiples, which were obtained by first calculating the relevant enterprise value multiples for each company (such as enterprise value divided by gross margin) and then calculating a weighted average of those multiples based on FPL Group and Constellation’s enterprise values relative to one another; and

•

FPL Group multiples, which were calculated by dividing FPL Group’s enterprise value as of December 13, 2005 by FPL Group’s projected gross margin, EBITDA and EBIT for each year.

In determining the potential contribution of each company, Goldman Sachs did not take into account any operating, financial or accounting impacts resulting from the merger, any cost savings or other benefits projected by Constellation and FPL Group to be realized from the merger or any other pro forma impacts of the merger. The results of this analysis are as follows:


	% Contribution:				Implied % of Combined Equity Value-Weighted Average Multiples:				Implied % of Combined Equity Value-FPL Group Multiples:

For each of the selected transactions, Goldman Sachs derived the equity and levered value of the target company implied by the transaction, based upon publicly available information. Levered value is defined as the equity value of the target company plus the target’s net debt plus the book value of the target’s preferred stock. Equity value is defined as fully diluted shares outstanding multiplied by the implied offer price for each share of the target company’s common stock. Goldman Sachs then calculated each target’s equity or levered value, as the case may be, as a multiple of forward EPS (meaning the target’s estimated EPS for the following year), LTM EBITDA, book value and net value of property, plant and equipment, or PP&E (to the extent that information was publicly available), and set forth the high, low, mean and median forward EPS, LTM EBITDA, book value and net PP&E multiples calculated for the relevant selected transactions. Data regarding forward EPS, LTM EBITDA, book value and net PP&E were based on publicly available information.

The following table shows the results of this analysis:


	High		Low		Mean		Median
Equity Value as a multiple of Forward EPS	15.0	x	11.4	x	13.8	x	14.4	x
Levered Value as a multiple of LTM EBITDA	12.2	x	6.6	x	8.7	x	8.5	x
Levered Value as a multiple of Book Value	3.2	x	0.9	x	1.7	x	1.6	x
Levered Value as a multiple of Net PP&E	2.2	x	0.8	x	1.6	x	1.6	x

Goldman Sachs also calculated various multiples for Constellation based upon the implied value of the merger, which are found under the heading “Implied Transactions Multiples Analysis” below.

Goldman Sachs also calculated the premium of each target’s per share consideration to the undisturbed stock price, which was defined as the 30 day prior average stock price, and to the 52-week high stock price of the target’s stock (to the extent that information was publicly available), and set forth the high, low, mean and median undisturbed stock price and 52-week high stock price premiums calculated for the relevant selected transactions. The following table shows the results of this analysis:


	High		Low		Mean		Median

52-Week High	17.4	%	1.4	%	8.2	%	8.0	%

In a separate analysis, Goldman Sachs calculated premiums based upon the implied exchange ratio, which are set forth under the heading “Transaction Premium Analysis” above.

Implied Transaction Multiples Analysis

Goldman Sachs reviewed selected multiples for Constellation, assuming completion of the merger, and compared that data to corresponding data for selected transactions and public companies. Goldman Sachs compared the implied equity value as a multiple of earnings for calendar years 2005 through 2007, the implied equity value as a multiple of book value as of September 30, 2005 and the implied transaction value as a multiple of LTM EBITDA and EBITDA for calendar years 2005 through 2007 to corresponding mean and median multiples for selected transactions and public companies that were used in the Selected Transactions Analysis and Selected Companies Analysis described above.

Goldman Sachs obtained the implied equity value of Constellation by calculating the product of (i) the implied exchange ratio of 1.444 shares of FPL Group common stock for each share of Constellation common stock, (ii) the $42.87 closing trading price per share of FPL Group common stock as of December 13, 2005 and (iii) the number of diluted shares of Constellation common stock as of year end 2005 based on the estimates of Constellation’s management. Goldman Sachs obtained the implied transaction value by adding net debt of Constellation to the implied equity value. The earnings and book value figures were based on the estimates of the management of Constellation and EBITDA was calculated as EBIT plus depreciation and amortization based on forecasts prepared by Constellation’s management. The following table compares the relevant multiples referred to above calculated for the selected transactions, selected public companies and Constellation:


	Selected Transactions				Selected Public Companies				Constellation

Merger of Equals Analysis

Goldman Sachs analyzed the premiums paid in the context of mergers of equals, which for purposes of this analysis means all-stock transactions between two companies in which the resulting ownership of the combined company by stockholders of either of the combining companies was not less than 40% nor greater than 60% of the combined company. For calendar years 2001 through 2005, Goldman Sachs then calculated the median

premium paid relative to the share price of the target company four weeks prior to the announcement of the transaction. The premiums used by Goldman Sachs in this analysis were based on information provided by SDC Platinum, a financial transactions database, and reflected information available as of December 5, 2005. The following table shows the results of this analysis for mergers of equals in the United States:


Calendar Year:	Median Premium Relative to Share Price 4 Weeks Prior to Announcement:
2001	11.1	%
2002	(8.1	)%
2003	0.1	%
2004	9.2	%
2005	7.5	%

The following table shows the results of this analysis for mergers of equals globally:


Calendar Year:	Median Premium Relative to Share Price 4 Weeks Prior to Announcement:
2001	11.2	%
2002	(8.1	)%
2003	1.0	%
2004	10.1	%
2005	5.0	%

In a separate analysis, Goldman Sachs calculated premiums based upon the implied exchange ratio, which are set forth under the heading “Transaction Premium Analysis” above.

Stand-Alone Discounted Cash Flow Analyses

Constellation Discounted Cash Flow Analysis

Goldman Sachs performed illustrative discounted cash flow analyses to determine indications of illustrative implied equity values for Constellation and illustrative implied equity values per share of Constellation common stock based on Constellation management’s forecasts. In performing the illustrative discounted cash flow analysis, Goldman Sachs calculated the aggregate future cash flows of Constellation and then discounted the value of those cash flows back to present value using discount rates ranging from 6.5% to 8.5%. For purposes of this analysis, Goldman Sachs utilized Constellation management’s projections of Constellation’s cash flows for calendar years 2006 through 2008. After 2008, cash flow was grown in perpetuity at perpetuity growth rates ranging from 3.00% to 4.00%. For purposes of the equity value per share analysis, Goldman Sachs utilized outstanding share information as of year end 2005 for Constellation as provided by the management of Constellation.

Based on the foregoing, Goldman Sachs derived illustrative implied equity values for Constellation ranging from $6,836 million to $19,984 million and illustrative implied equity values per share ranging from $37.83 to $110.59 per share with respect to Constellation common stock. Applying the mid-point discount rate of 7.5% and the mid-point perpetuity growth rate of 3.50%, Goldman Sachs derived an illustrative implied equity value for Constellation of $10,945 million, an illustrative implied equity value per share of $60.57 with respect to Constellation common stock.

FPL Group Discounted Cash Flow Analysis

Goldman Sachs performed illustrative discounted cash flow analyses to determine indications of illustrative implied equity values for FPL Group and illustrative implied equity values per share of FPL Group common

stock based on forecasts delivered by the management of Constellation. In performing the illustrative discounted cash flow analysis, Goldman Sachs calculated the aggregate future cash flows of FPL Group and then discounted the value of those cash flows back to present value using discount rates ranging from 5.25% to 7.25%. For purposes of this analysis, Goldman Sachs utilized projections of FPL Group’s cash flows for calendar years 2006 through 2008 delivered by the management of Constellation. After 2008, cash flow was grown in perpetuity at perpetuity growth rates ranging from 2.50% to 3.50%. For purposes of the equity value per share analysis, Goldman Sachs utilized outstanding share information as of year end 2005 for FPL Group as provided by the management of Constellation.

Based on the foregoing, Goldman Sachs derived illustrative implied equity values for FPL Group ranging from $8,611 million to $40,523 million, illustrative implied equity values per share ranging from $22.38 to $105.33 per share with respect to FPL Group common stock and implied terminal value multiples for 2008 EBITDA ranging from 5.5x to 15.1x. Applying the mid-point discount rate of 6.25% and the mid-point perpetuity growth rate of 3.00%, Goldman Sachs derived an illustrative implied equity value for FPL Group of $17,204 million, an illustrative implied equity value per share of $44.72 with respect to FPL Group common stock.

Combined Company Discounted Cash Flow Analysis

Goldman Sachs performed illustrative discounted cash flow analyses to determine indications of illustrative implied equity values for Constellation’s implied 40% share of the combined company and illustrative implied equity values per share of the common stock of the combined company utilizing forecasts prepared by the management of Constellation and assuming the completion of the merger. In performing the illustrative discounted cash flow analysis, Goldman Sachs calculated the aggregate future cash flows of the combined company and then discounted the value of those cash flows back to present value using discount rates ranging from 5.75% to 7.75%. For purposes of this analysis, Goldman Sachs utilized Constellation management’s projections of the combined company’s cash flows for calendar years 2006 through 2008. After 2008, cash flow was grown in perpetuity at perpetuity growth rates ranging from 2.75% to 3.75%. For purposes of this analysis, Goldman Sachs utilized outstanding share information as of year end 2005 for the combined company as provided by Constellation’s management and assumed synergies projected by Constellation’s management to result from the merger.

Based on the foregoing, Goldman Sachs derived illustrative implied equity values for Constellation’s implied 40% share of the combined company ranging from $6,822 million to $25,326 million and illustrative implied equity values ranging from $37.76 to $140.16 per share of the common stock of the combined company. Applying the mid-point discount rate of 6.75% and the mid-point perpetuity growth rate of 3.25%, Goldman Sachs derived an illustrative implied equity value for Constellation’s implied 40% share of the combined company of $12,139 million and an illustrative implied equity value of $67.18 per share of the common stock of the combined company.

Analysis of Present Value of Hypothetical Future Stock Prices

Constellation Common Stock

Goldman Sachs calculated a range of hypothetical present values of the future price for, and dividends paid on, the Constellation common stock using Constellation management’s estimates of Constellation’s quarterly dividend for the calendar years 2006 through 2008 and of Constellation’s projected 2008 EPS. In performing this analysis, Goldman Sachs:

•

multiplied projected 2008 EPS by a 12% growth rate and P/E ratios ranging from 12.0x to 15.0x in order to calculate a range of hypothetical stock prices for the Constellation common stock as of December 31, 2008;

•

added to the ranges of hypothetical stock prices the total amount of dividends that Constellation’s management estimated would be paid on the Constellation common stock up to December 31, 2008; and

•

discounted the hypothetical future stock prices and aggregate amount of dividends back to present value using discount rates ranging from 9% to 11%.

The results of Goldman Sachs’ analysis are set forth below:


Discount Rate:	Range of Illustrative Present Values of Future Stock Price and Dividend:
9%	$	59.55 - $73.41
10%	$	58.00 - $71.48
11%	$	56.50 - $69.62

Pro Forma Constellation Common Stock Adjusted for the Exchange Ratio

Goldman Sachs calculated a range of hypothetical present value of the future prices for, and dividends paid on, the Constellation common stock, after giving effect to the merger, using Constellation management’s estimates of the combined company’s quarterly dividend for the calendar years 2006 through 2008 and of the combined company’s projected 2008 EPS. In performing this analysis, Goldman Sachs:

•

multiplied projected 2008 EPS by a 12% growth rate and P/E ratios ranging from 13.0x to 16.0x in order to calculate a range of hypothetical stock prices for the combined company’s common stock as of December 31, 2008;

•

added to the ranges of hypothetical stock prices the total amount of dividends that Constellation’s management estimated would be paid on the combined company’s common stock up to December 31, 2008; and

•

discounted the hypothetical future stock prices and aggregate amount of dividends back to present value using discount rates ranging from 8% to 10%.

The results of Goldman Sachs’ analysis are set forth below:


Discount Rate:	Range of Illustrative Present Value of Future Stock Price and Dividend:
8%	$	70.26 - $85.04
9%	$	68.43 - $82.81
10%	$	66.67 - $80.66

Pro Forma EPS and Dividend Accretion/Dilution Analyses

Goldman Sachs performed an illustrative pro forma EPS analysis to assess whether the merger would increase or reduce Constellation and FPL Group’s projected EPS for years 2006 through 2008. For purposes of this analysis, Goldman Sachs used estimates for Constellation, estimates for FPL Group and estimates of synergies projected to result from the merger, that were delivered to Goldman Sachs by the management of Constellation. In preparing these analyses, Goldman Sachs assumed that the implied per share merger consideration to be paid by FPL Group to holders of Constellation common stock will consist of FPL Group common stock based on the exchange ratio contemplated by the merger agreement.

Based on the foregoing analysis, Goldman Sachs calculated that the merger would be :

•

dilutive to (or reduce) FPL Group’s EPS in 2006 and accretive to (or increase) FPL Group’s EPS in 2007 and 2008;

•

accretive to Constellation’s EPS in 2006 and 2008 and dilutive to Constellation’s EPS in 2007; and

•

significantly accretive to Constellation’s dividend in 2006, 2007 and 2008.

Based on the foregoing analysis and taking into account certain purchase accounting adjustments, which were provided to Goldman Sachs by the management of Constellation, Goldman Sachs calculated that the merger would be:

•

significantly accretive to FPL Group’s EPS in 2006, 2007 and 2008;

•

significantly accretive to Constellation’s EPS in 2006, 2007 and 2008; and

•

significantly accretive to Constellation’s dividend in 2006, 2007 and 2008.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Constellation or FPL Group or the contemplated merger.

Goldman Sachs prepared these analyses for purposes of Goldman Sachs’ providing its opinion to the Constellation board of directors that the exchange ratio, assuming the prior effectiveness of the stock split, pursuant to the merger agreement was fair from a financial point of view to the holders of the Constellation common stock. Goldman Sachs’ opinion does not address the underlying business decision of Constellation to engage in the transaction nor did Goldman Sachs expressing any opinion as to the prices at which Constellation common stock or FPL Group common stock will trade at any time. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Constellation, FPL Group, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecasted.

The exchange ratio contemplated by the merger agreement was determined through arms’-length negotiations between Constellation and FPL Group and was approved by the Constellation board of directors. Goldman Sachs did not recommend any specific exchange ratio to Constellation or its board of directors or that any exchange ratio constituted the only appropriate exchange ratio for the merger. Goldman Sachs was engaged solely for the purpose of undertaking a study to enable it to render its opinion to the Constellation board of directors as to the fairness from a financial point of view to the holders of the Constellation common stock of the exchange ratio contemplated by the merger agreement, assuming the effectiveness of the stock split, pursuant to the merger agreement and did not participate in the negotiations leading to the proposed merger.

As described above, Goldman Sachs’ opinion to the Constellation board of directors was one of many factors taken into consideration by the Constellation board of directors in making its decision to approve the merger agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with its fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex C to this joint proxy statement/prospectus.

Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Goldman Sachs has provided certain investment banking and other services to Constellation from time to time, including having extended an unfunded loan commitment (aggregate principal amount $155,000,000) to Constellation in November 2005. Goldman Sachs also may provide investment banking services to Constellation and FPL Group

in the future. In connection with the above-described investment banking and other services, Goldman Sachs has received, and may receive, compensation.

In addition to the foregoing, Goldman Sachs Power LLC, an affiliate of Goldman Sachs (which we refer to herein as Goldman Sachs Power), is party to an Amended and Restated Software Development and License Agreement, dated as of October 25, 2001 (which we refer to herein as the Amended License Agreement), with Constellation Energy Commodities Group, Inc., a subsidiary of Constellation formerly known as Constellation Power Source, Inc. (which we refer to herein as CCG). The Amended License Agreement was entered into in connection and contemporaneously with the termination of certain business arrangements between Goldman Sachs Power and certain of its affiliates, on the one hand, and Constellation and CCG, on the other hand. Goldman Sachs Power has advised CCG that the Amended License Agreement would remain in effect between the parties following the completion of the merger.

Furthermore, Indiantown Cogeneration, L.P. and Cedar Bay Generating Company, Limited Partnership, entities that are indirectly owned by Cogentrix Energy, Inc., an indirect wholly owned subsidiary of The Goldman Sachs Group, Inc., the parent company of Goldman Sachs, were plaintiffs in two lawsuits that were pending on December 18, 2005 against affiliates of FPL Group relating to contract disputes. The captions of the cases are Indiantown Cogeneration, L.P. v. Florida Power & Light Company (pending in the U.S. District Court for the Middle District of Florida) and Cedar Bay Generating Company, Limited Partnership v. Florida Power & Light Company (pending in the Fourth Judicial Circuit Court, Duval County Florida). These cases have been dismissed without prejudice.

Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide such services to Constellation, FPL Group and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of Constellation and FPL Group for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

The Constellation board of directors engaged Goldman Sachs because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement, dated December 9, 2005, Constellation agreed to pay Goldman Sachs a fee of $5,000,000 for its services, which was payable upon Goldman Sachs’ delivery of its opinion. In addition, Constellation has agreed to reimburse Goldman Sachs for its expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including liabilities under the federal securities laws.

FPL Group’s Reasons for the Merger; Recommendation of the FPL Group Board of Directors

The FPL Group board of directors has approved the merger agreement, has determined that the merger agreement and the transactions contemplated thereby, including the merger, are fair to and in the best interests of FPL Group and FPL Group shareholders, and recommends that FPL Group shareholders vote FOR the proposal to approve the merger agreement.

In evaluating the merger, the FPL Group board of directors consulted with management, as well as Merrill Lynch, FPL Group’s financial advisor in connection with the merger, Lehman Brothers, which was engaged to render a fairness opinion to the FPL Group board of directors with respect to the merger, Cravath, Swaine & Moore LLP, FPL Group’s outside transaction counsel, and Skadden, Arps, Slate, Meagher & Flom LLP, FPL Group’s outside federal regulatory counsel, and considered a number of factors, including those described below. The following discussion of the information and factors considered by the FPL Group board of directors is not intended to be exhaustive. In view of the wide variety of factors considered by the FPL Group board of directors in connection with its evaluation of the merger, the FPL Group board of directors did not consider it practical to,

nor did it attempt to, quantify, rank, or otherwise assign relative weights to the specific factors it considered in reaching its decision. In addition, individual members of the FPL Group board of directors may have given different weight to different factors. The FPL Group board of directors considered this information and these factors as a whole and overall considered the relevant information and factors to be favorable to, and in support of, its determinations and recommendations. Among the information and factors considered by the FPL Group board of directors were the following:

Strategic Considerations. The FPL Group board of directors considered a number of factors pertaining to the strategic rationale for the merger, including the following:

•

Expanded Scale, Skill, Scope and Diversification. The combined company will have a leading platform in the competitive energy sector, a more diversified utility business and multiple tangible growth opportunities. The combined company is expected to be the nation’s largest competitive energy supplier and have the second-largest electric utility portfolio in the United States and the largest generation portfolio in the United States, with more than 45,000 megawatts of generation. FPL Group believes that the combined company will have one of the biggest and fastest-growing utility businesses in the United States as well as a competitive energy business with greater diversity in its customer mix in terms of size, geography and contract length.

•

Leading Competitive Energy Business. FPL Group believes that the merger will create a premier competitive energy company in the United States which will benefit from increased fuel and market diversity and the combination of FPL Group’s and Constellation’s complementary assets and skill bases. FPL Group further believes that the combined company will lower its costs and better serve customers by matching FPL Group’s generation assets with Constellation’s leading competitive supply portfolio. FPL Group expects the combined company to be the market leader in both competitive retail and key wholesale markets, including New England and the Pennsylvania New Jersey Maryland Interconnection LLC region (which we refer to herein as PJM). The combined company will be the second largest independent power producer in the United States, based on total megawatts of generating assets currently in operation in deregulated markets, with assets in key regions, including the Northeast, California, PJM and the Texas markets. FPL Group believes that the combined company will have significant opportunities for generation margin expansion resulting from lower-priced hedges and contracts rolling off and being replaced with new contracts at market prices. FPL Group further believes that a more balanced combined merchant power business will be better positioned to take advantage of future opportunities in the electric wholesale market.

•

Stronger Utility Business Platform. The merger is expected to create the second-largest electric utility portfolio in the United States, and the combined company will have greater diversification of regulatory regimes. In addition, FPL Group believes that, by sharing expertise, the merger will result in a better opportunity for both utilities to better serve customers and assist each other in the event of natural disasters.

•

Enhanced Nuclear Expertise. The combined company will have expanded nuclear operations with potential for increased savings and efficiencies. FPL Group believes that the combined company’s nuclear operations will bring an increased depth of resources and talent and provide a strong platform to pursue continued nuclear consolidation and to potentially develop a new nuclear program.

•

Anticipated Financial Strength and Flexibility. FPL Group believes that the combined company will have diversified energy supply and generation portfolios. FPL Group further believes that the combined company will have a solid base of stable growing earnings and cash flow built on a strong balance sheet.

•

Compatible Business Model. FPL Group believes that FPL Group and Constellation have largely compatible business models, including both companies’ utility businesses, large nuclear fleets and competitive wholesale and retail supply businesses.

•

More Diverse and Balanced Fuel Mix. The combined company will have a more balanced fuel mix and a broader geographic coverage, which will improve load-serving capabilities. The combined company, which will have the largest wind generation portfolio in the United States as well as significantly improved coal and nuclear expertise, is expected to be able to reduce fuel risk exposure and increase purchasing power.

•

Combined Expertise. FPL Group believes that the merger will combine complementary areas of expertise: FPL Group’s expertise in operations and wind energy and Constellation’s risk management, commodity and retail expertise. The combined company is expected to be able to draw upon the intellectual capital, technical expertise and experience of a deeper, more diverse workforce.

•

Impact on Florida Power & Light’s Customers. The FPL Group board of directors considered the impact of the merger on Florida Power & Light’s customers. Specifically, the FPL Group board of directors believes that the merger should benefit Florida Power & Light’s customers through a broader range of coal and nuclear expertise and modest, direct cost savings.

Cost Savings and Synergies. The FPL Group board of directors considered that, although no assurances can be given that any particular level of cost savings and other synergies will be achieved, FPL Group management had identified estimated revenue and cost synergies of approximately $200 to $250 million annually before integration-related costs by the end of the third year of the combination. A substantial majority of these synergies are expected to come from competitive energy businesses. These cost savings are expected to result from consolidation of competitive energy business unit operations, improved procurement strategies (including from increased purchasing leverage) and consolidation of information systems and corporate overhead/support activities (including from a consolidated staff and transaction processing support) . The FPL Group board of directors noted that expected cost savings and synergies are estimates, that they may change and that achieving the expected cost savings and synergies is subject to a number of risks and uncertainties. FPL Group management did not compare the estimated synergies related to the merger to synergies of other potential transactions because FPL Group was not actively considering any other potential business combination transaction at the relevant time. See “The Introduction—Risk Factors—Risks Relating to the Merger—Stockholders may not realize all of the anticipated benefits of combining Constellation and FPL Group” beginning on page 24.

Share Price; Tax-Free Exchange. The FPL Group board of directors considered the historical stock prices of FPL Group and Constellation, including that the exchange ratio for the Constellation stockholders (giving effect to the stock split) represented a premium of approximately 14.8% based on the exchange ratio calculated using the average of the 20-day closing prices of Constellation and FPL Group common stock for the period ending December 13, 2005, the last trading day prior to the first public reports of a possible transaction between FPL Group and Constellation. The FPL Group board of directors also considered that the merger is designed to be tax-free to the holders of FPL Group common stock.

Financial Considerations. The FPL Group board of directors considered the expected earnings, cash flow, balance sheet and dividend impact of the merger, the expected market reaction to the merger and the financial prospects of FPL Group and Constellation. The FPL Group board of directors also considered the historical financial condition and operating results of FPL Group and Constellation, as well as historical stock market information. The FPL Group board of directors believes that the merger will be accretive to FPL Group shareholders in the first full year of combined operations, excluding transaction and integration costs related to the merger. The FPL Group board of directors expects that the combined company’s dividend will be the same as that of FPL Group immediately prior to the completion of the merger.

Impact of the Merger on Communities. The FPL Group board of directors evaluated the expected impact of the merger on the communities in which FPL Group and Constellation are located and which they serve. In particular, the FPL Group board of directors believes that the merger will benefit the municipalities served by the combined company by creating a Fortune 100 company able to provide more reliable service with a shared

commitment to clean energy and other environmental concerns. In addition, the companies expect to maintain their substantial presence in the cities and communities they serve, including continuing significant charitable contributions.

Opinions of Financial Advisors. The FPL Group board of directors considered the financial analyses and presentation of Merrill Lynch presented to the FPL Group board of directors at its meeting on December 16, 2005 and also considered the oral opinion of Merrill Lynch to the FPL Group board of directors, subsequently confirmed in writing on December 18, 2005, that, as of that date, and subject to and based upon the various assumptions, limitations and qualifications set forth in such written opinion, the exchange ratio in the merger was fair from a financial point of view to the holders of FPL Group common stock. See “—Opinions of FPL Group’s Financial Advisors—Opinion of Merrill Lynch, Pierce, Fenner & Smith Incorporated” beginning on page 85. The FPL Group board of directors also considered the financial analyses and presentation of Lehman Brothers in connection with the merger, presented to the FPL Group board of directors at its meeting on December 16, 2005 and also considered the oral opinion of Lehman Brothers to the FPL Group board of directors subsequently confirmed in writing on December 18, 2005, that, as of that date and subject to and based upon the various assumptions, limitations and qualifications set forth in such written opinion, from a financial point of view, the exchange ratio in the merger, assuming the prior effectiveness of the stock split, to be offered to holders of FPL Group common stock was fair to the holders of FPL Group common stock. See “—Opinions of FPL Group’s Financial Advisors—Opinion of Lehman Brothers Inc.” beginning on page 95.

Recommendation of Management. The FPL Group board of directors considered management’s recommendation in support of the merger.

Terms of the Merger Agreement. The FPL Group board of directors reviewed the terms of the merger agreement, including the representations and warranties, obligations and rights of the parties under the merger agreement, the conditions to each party’s obligation to complete the merger, the rights of each party to consider and engage in negotiations regarding potentially superior proposals, the rights of each party to withdraw or otherwise change its recommendation to its shareholders in favor of the proposals related to the merger agreement, the instances in which each party is permitted to terminate the merger agreement and the related termination fees payable by each party in the event of termination of the merger agreement under specified circumstances. See “—The Merger Agreement” beginning on page 132 for a detailed discussion of the terms and conditions of the merger agreement. The FPL Group board of directors also considered the course of negotiations of the merger agreement.

Due Diligence. The FPL Group board of directors considered the scope of the due diligence investigation conducted by management and FPL Group’s outside advisors and evaluated the results thereof.

Corporate Governance. The FPL Group board of directors considered the corporate governance provisions of the merger agreement to be adopted by Constellation upon completion of the merger, including that Lewis Hay, III will be the Chief Executive Officer of the combined company, and that the board of directors of the combined company will be composed of nine persons who served as directors of FPL Group prior to the completion of the merger and six persons who served as directors of Constellation prior to the completion of the merger.

Strategic Alternatives. The FPL Group board of directors considered the trends and developments in the industry and the range of strategic alternatives available to FPL Group, including the possibility of business combinations with other participants in the industry (none of which were being actively considered at the time) or continuing to operate as a stand-alone entity.

Likelihood of Completion of the Merger. The FPL Group board of directors considered the likelihood that the merger will be completed on a timely basis, including the likelihood that the merger will receive all necessary regulatory approvals without unacceptable conditions.

The FPL Group board of directors also considered the potential risks of the merger, including the following:

Fixed Exchange Ratio. The FPL Group board of directors considered that the fixed exchange ratio will not adjust downwards to compensate for declines in the price of Constellation common stock prior to the closing of the merger and that the terms of the merger agreement do not include termination rights triggered expressly by a decrease in value of Constellation due to a decline in the market price of the Constellation common stock. The FPL Group board of directors determined that this structure was appropriate and the risk acceptable in view of: the FPL Group board of directors’ focus on the relative intrinsic values and financial performance of FPL Group and Constellation and the percentage of the combined company to be owned by holders of FPL Group common stock prior to the merger; and the inclusion in the merger agreement of conditions to the obligations of FPL Group to effect the merger such as the absence of a material adverse change in Constellation’s business.

Constellation Business Risks. The FPL Group board of directors considered certain risks inherent in Constellation’s business and operations, including risks associated with Constellation’s competitive supply business operations (including its nuclear operations), risks relating to Constellation’s proprietary trading, the regulatory environment in Maryland and its impacts on BGE and Constellation’s environmental and other contingent liabilities. Based on reports of management and outside advisors regarding the due diligence process, the FPL Group board of directors believes that these risks are manageable as part of the ongoing business of the combined company.

Severance and Retention Arrangements. The FPL Group board of directors considered the severance and retention arrangements covering executives and employees of Constellation and related costs and the impact of such arrangements on the retention of key management of Constellation.

Regulatory Approvals. The FPL Group board of directors considered the regulatory approvals required to complete the merger and the risk that governmental authorities and third parties might seek to impose unfavorable terms or conditions as part of granting the required approvals or that such approvals may not be obtained at all. The FPL Group board of directors further considered the potential length of the regulatory approval process and the period of time FPL Group may be subject to the merger agreement.

Diversion of Management. The FPL Group board of directors considered the possible diversion of management resulting from the substantial time and effort necessary to complete the merger and integrate the operations of FPL Group and Constellation following completion of the merger.

Impact on Credit Rating and Risk Profile. The FPL Group board of directors considered the possibility that the merger could impact the credit rating of the combined company and certain of its subsidiaries, and assessed the potential effect of a change in the credit rating.

Restrictions on Interim Operations. The FPL Group board of directors considered the provisions of the merger agreement placing restrictions on FPL Group’s operations during the period prior to completion of the merger.

Increased Regulation. The FPL Group board of directors considered the additional regulation, including the regulatory oversight that would result from the addition of public utility operations in Maryland, to which the combined company will be subject. The FPL Group board of directors also considered the potential impact of new federal environmental regulations and proposed state environmental regulation on the future operations of the combined company.

Termination Fee; Alternative Proposals. The FPL Group board of directors considered the risk that, although FPL Group has the right under certain limited circumstances to consider and participate in negotiations with respect to alternative acquisition proposals, the provisions of the merger agreement relating to the potential payment of a termination fee of $650 million may have the effect of discouraging such proposals. In addition, the FPL Group board of directors considered that, under specified circumstances, FPL Group would be required to

pay to Constellation a fee of $100 million or reimburse Constellation for its out-of-pocket expenses, although in no event would the aggregate amount payable by FPL Group to Constellation exceed $650 million, which payment obligations also could have the effect of discouraging alternative proposals. The merger agreement also includes other customary restrictions on the ability of FPL Group to solicit offers for alternative proposals or engage in discussions regarding such proposals, subject to exceptions, which could have the effect of discouraging such proposals from being made or pursued. The FPL Group board of directors understood that these provisions may have the effect of discouraging alternative proposals and may make it less likely that the transactions related to such proposals would be negotiated or pursued, even if potentially more favorable to the shareholders of FPL Group than the merger. See “—The Merger Agreement—Termination of Merger Agreement—Termination Fees/Reimbursement of Expenses Payable by FPL Group” beginning on page 144 for further information.

Integration. The FPL Group board of directors evaluated the challenges inherent in the merging of two business enterprises of the size and scope of FPL Group and Constellation, including the possibility of not achieving the anticipated cost-savings and synergies and other benefits sought to be obtained from the merger.

Personnel. The FPL Group board of directors considered the adverse impact that business uncertainty pending completion of the merger could have on the ability to attract, retain and motivate key personnel until the merger is completed. The FPL Group board of directors also considered other adverse impacts that the merger could have on the retention of key employees.

Interests of Executive Officers and Directors. The FPL Group board of directors considered that certain executive officers and directors of FPL Group may have interests with respect to the merger in addition to their interests as shareholders of FPL Group, including that Mr. Hay was expected to be Chief Executive Officer of the combined company and that other FPL Group executive officers were also expected to have positions with the combined company. See “— Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger” beginning on page 113 for further information.

The FPL Group board of directors believed that, overall, the potential benefits of the merger to FPL Group and the FPL Group shareholders outweighed the risks.

The FPL Group board of directors realized that there can be no assurance about future results, including results considered or expected as described in the factors listed above. It should be noted that this explanation of the FPL Group board of directors’ reasoning and all other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Note Regarding Forward-Looking Statements” beginning on page 34.

Opinions of FPL Group’s Financial Advisors

On October 1, 2005, FPL Group engaged Merrill Lynch to act as its lead financial advisor in connection with the proposed merger. On December 16, 2005, Merrill Lynch delivered its oral opinion to the FPL Group board of directors, subsequently confirmed in its written opinion dated December 18, 2005, that, as of that date, and based upon and subject to the assumptions made, matters considered and qualifications and limitations set forth in the written opinion, the exchange ratio of 1.000 share of Constellation common stock for each share of FPL Group common stock provided for in the merger, subject to the prior effectiveness of the stock split whereby each outstanding share of Constellation common stock will be automatically converted into, assuming the effectiveness of the merger, 1.444 shares of Constellation common stock, was fair, from a financial point of view, to the holders of FPL Group common stock.

The full text of the written opinion of Merrill Lynch, which sets forth the assumptions made, matters considered and qualifications and limitations on the review undertaken by Merrill Lynch, is attached as Annex D to this joint proxy statement/prospectus and is incorporated into this joint proxy statement/

prospectus by reference. The following summary of Merrill Lynch’s opinion is qualified in its entirety by reference to the full text of the opinion.

Merrill Lynch’s opinion does not constitute a recommendation to any FPL Group shareholder as to how such shareholder should vote with respect to the proposed merger or any matter related thereto. Merrill Lynch has consented to the inclusion in this joint proxy statement/prospectus of its written opinion and of the summary of that opinion set forth below.

In December 2005, FPL Group engaged Lehman Brothers to act as advisor to its board of directors to render to the FPL Group board of directors an opinion with respect to the merger. On December 16, 2005, Lehman Brothers rendered its preliminary oral opinion which was subsequently confirmed in writing on December 18, 2005 to the FPL Group board of directors that as of such date and, based upon and subject to certain matters stated in such opinion, from a financial point of view, the exchange ratio, assuming the prior effectiveness of the stock split, to be offered to the shareholders of FPL Group in the merger is fair to the shareholders of FPL Group.

The full text of Lehman Brothers’ written opinion, dated as of December 18, 2005 is attached as Annex E to this joint proxy statement/prospectus. You are urged to read Lehman Brothers’ opinion carefully in its entirety for a description of the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Lehman Brothers in rendering its opinion.

Opinion of Merrill Lynch, Pierce, Fenner & Smith Incorporated

In arriving at its opinion, Merrill Lynch, among other things:

•

reviewed certain publicly available business and financial information relating to Constellation and FPL Group that Merrill Lynch deemed to be relevant;

•

reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of Constellation and FPL Group, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the merger, which is referred to as the expected synergies, furnished to Merrill Lynch by Constellation and FPL Group, respectively;

•

conducted discussions with members of senior management and representatives of Constellation and FPL Group concerning the matters described in the first two bullets above, as well as their respective businesses and prospects before and after giving effect to the merger and the expected synergies;

•

reviewed the market prices and valuation multiples for Constellation common stock and FPL Group common stock and compared them with those of certain publicly traded companies that Merrill Lynch deemed to be relevant;

•

reviewed the results of operations of Constellation and FPL Group and compared them with those of certain publicly traded companies that Merrill Lynch deemed to be relevant;

•

compared the proposed financial terms of the merger with the financial terms of certain other transactions that Merrill Lynch deemed to be relevant;

•

participated in certain discussions and negotiations among representatives of Constellation and FPL Group and their financial and legal advisors;

•

reviewed the potential pro forma impact of the merger;

•

reviewed the merger agreement dated December 18, 2005; and

•

reviewed such other financial studies and analyses and took into account such other matters as Merrill Lynch deemed necessary, including its assessment of general economic, market and monetary conditions.

In preparing its opinion, Merrill Lynch assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to it, discussed with or reviewed by or for it, or that was publicly available. Merrill Lynch did not assume any responsibility for independently verifying such information and did not undertake any independent evaluation or appraisal of any of the assets or liabilities of Constellation or FPL Group and it was not furnished with any such evaluation or appraisal, nor did it evaluate the solvency or fair value of Constellation or FPL Group under any state or federal laws relating to bankruptcy, insolvency or similar matters. In addition, Merrill Lynch did not assume any obligation to conduct any physical inspection of the properties or facilities of Constellation or FPL Group. With respect to the financial forecast information relating to Constellation and FPL Group and the expected synergies prepared by the management of FPL Group and furnished to or discussed with Merrill Lynch by Constellation or FPL Group, Merrill Lynch assumed, with the consent of the FPL Group board of directors, that they had been reasonably prepared and reflected the best currently available estimates and judgments of the management of Constellation or FPL Group as to the expected future financial performance of Constellation or FPL Group, as the case may be, and the expected synergies. Merrill Lynch expressed no opinion as to such financial forecast information, the expected synergies or the assumptions on which they are based. Merrill Lynch further assumed that the merger will qualify as a tax-free reorganization for U.S. federal income tax purposes and that the final form of the merger agreement would be substantially similar to the last draft reviewed by it.

Merrill Lynch’s opinion is necessarily based upon market, economic and other conditions as they existed and could be evaluated on, and on the information made available to Merrill Lynch as of, December 18, 2005. Merrill Lynch further assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the merger, no restrictions, including any divestiture requirements or amendments or modifications, would be imposed that would have a material adverse effect on the contemplated benefits of the merger. Merrill Lynch did not express any opinion as to the prices at which Constellation common stock or FPL Group common stock would trade following the announcement of the merger or the price at which Constellation common stock would trade following the completion of the merger.

Merrill Lynch’s Financial Analyses

The following is a summary of the material financial analyses that Merrill Lynch performed in connection with its opinion to the FPL Group board of directors. The financial analyses summarized below include information presented in tabular format. In order to understand fully the financial analyses performed by Merrill Lynch, the tables must be read together with the text of the summary. The tables alone do not constitute a complete description of the financial analyses, and if viewed in isolation could create a misleading or incomplete view of the financial analyses performed by Merrill Lynch. To the extent the following quantitative information reflects market data, except as otherwise indicated, Merrill Lynch based this information on market data as they existed prior to December 18, 2005. This information, therefore, does not necessarily reflect current or future market conditions.

In preparing its opinion to the FPL Group board of directors, Merrill Lynch performed various financial and comparative analyses, including those described below. The summary set forth below does not purport to be a

complete description of the analyses underlying Merrill Lynch’s opinion or the presentation made by Merrill Lynch to the FPL Group board of directors. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Merrill Lynch did not attribute any particular weight to any analysis or factor considered by it, but rather made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. Accordingly, Merrill Lynch believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors, or focusing on information presented in tabular format, without considering all of the analyses and factors or the narrative description of the analyses, would create a misleading or incomplete view of the process underlying its opinion.

In performing its analyses, Merrill Lynch made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Merrill Lynch. Any estimates contained in the analyses performed by Merrill Lynch are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than those suggested by such analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, as described above, the opinion of Merrill Lynch was one of several factors taken into consideration by the FPL Group board of directors in making its determination to approve the merger agreement. Consequently, Merrill Lynch’s analyses should not be viewed as determinative of the decision of the FPL Group board of directors with respect to the fairness from a financial point of view of the exchange ratio provided for in the merger agreement.

Analysis of Constellation

Historical Trading Performance

Merrill Lynch reviewed historical trading prices for Constellation common stock. The review indicated that for the 52-week period beginning on December 14, 2004 and ending on December 13, 2005, Constellation common stock traded as low as $43.08 per share and as high as $62.14 per share. These trading prices were compared to the closing price per share of Constellation common stock on December 13, 2005, one day prior to media reports of a potential merger, of $56.27; and the implied offer value per Constellation share of $61.90 implied from the exchange ratio of 1.000 provided for in the merger agreement, the split ratio of 1.444 for the Constellation stock split and the closing price of FPL Group common stock on December 13, 2005.

Research Analysts’ Price Targets

Merrill Lynch reviewed the most recent research analysts’ per share target prices for Constellation common stock, which ranged from $57.00 to $75.00 compared with the implied offer value per Constellation share of $61.90.

Analysis of Selected Comparable Publicly Traded Companies

Based on financial projections provided by Constellation’s management and FPL Group’s management, Merrill Lynch compared financial and operating information and ratios for Constellation with the corresponding financial and operating information and ratios for the following publicly traded companies in the energy industry that Merrill Lynch, in its professional judgment, deemed to be comparable to Constellation:

•

Edison International,

•

Exelon Corp. (pro forma for the merger with PSEG announced on December 20, 2004),

•

FPL Group,

•

PPL Corp.,

•

Sempra Energy, and

•

TXU Corp.

The financial and operating information and ratios reviewed by Merrill Lynch included, among other things:

•

the ratio of price per share to estimated earnings per share, commonly referred to as EPS, for 2006; and

•

the ratio of total enterprise value (calculated as equity market value, plus total debt (excluding securitization debt), preferred stock and minority interests, less cash and cash equivalents) to estimated earnings before interest, taxes, depreciation and amortization, commonly referred to as EBITDA (adjusted to eliminate cash flows dedicated to servicing securitization debt), for 2006.

All multiples were based on closing stock prices on December 13, 2005. Estimated financial data for the selected comparable companies were based on First Call estimates and publicly available research analysts’ estimates. Merrill Lynch also calculated the approximate after-tax net present value of expected synergies (taking into account the costs to achieve such synergies) to be received by FPL Group shareholders in the merger to be $1.081 billion and considered the impact of such expected synergies in each of the EPS and EBITDA analyses.

The following table reflects the ranges of implied values per share of Constellation common stock resulting from these analyses:


	Price Per Share to Estimated 2006 EPS		Enterprise Value to Estimated 2006 EBITDA
Comparable Companies: No Synergies	$	43.62-$62.86	$	52.40-$69.88
Comparable Companies: With Synergies	$	49.56-$68.80	$	58.34-$75.82

Each implied per share value of Constellation common stock derived from Merrill Lynch’s comparable company analyses was compared to the per share value for Constellation implied in the merger of $61.90 and the closing price of Constellation common stock on December 13, 2005 of $56.27 per share.

Sum-of-the-Parts Selected Comparables Analyses

•

utility,

•

merchant energy,

•

other non-regulated, and

•

synfuel tax credits.

Based on financial projections provided by Constellation’s management and FPL Group’s management, Merrill Lynch compared financial and operating information and ratios for the utility segment with the corresponding financial and operating information and ratios for the following publicly traded companies with operations, which Merrill Lynch, in its professional judgment, deemed to be comparable to Constellation’s utility segment:

•

CenterPoint Energy, Inc.,

•

Consolidated Edison Inc.,

•

Energy East Corp.,

•

Northeast Utilities,

•

NSTAR,

•

Pepco Holdings Inc., and

•

PG&E Corp.

Merrill Lynch analyzed the merchant energy segment by dividing it into three sub-segments:

•

mid-Atlantic region generation plants, Power Purchase Agreement-based generation plants and qualifying facilities;

•

wholesale/trading; and

•

retail.

With respect to the first sub-segment, Merrill Lynch analyzed the purchase price and implied transaction multiples paid in transactions involving energy generating assets based on the type of fuel such assets used to generate energy, which Merrill Lynch, in its professional judgment, deemed to be relevant. Merrill Lynch reviewed transactions involving facilities that used nuclear, coal, oil, gas and hydro power to generate energy, and analyzed the transaction value of such transactions as a multiple of kilowatt of net installed capacity. Merrill Lynch validated the results of its kilowatt of net installed capacity multiple analyses for the mid-Atlantic region generation plants, Power Purchase Agreement-based generation plants and qualifying facilities included in the merchant energy segment by also performing an analysis of implied multiples of 2007 estimated EBITDA for these plants and facilities.

With respect to the wholesale/trading sub-segment, Merrill Lynch compared financial information and ratios with the corresponding financial information and ratios for a selected range of companies engaged in the business of trading and exchanging financial and commodity products, which Merrill Lynch, in its professional judgment, deemed to be comparable to Constellation’s wholesale/trading sub-segment.

With respect to the retail sub-segment, Merrill Lynch analyzed, among other things, the purchase prices and implied transaction multiples paid in comparable transactions involving target companies in the retail energy business, which Merrill Lynch, in its professional judgment, deemed to be relevant.

With respect to the other non-regulated segment, Merrill Lynch compared financial and operating information and ratios with the corresponding financial and operating information and ratios for energy-related industrial service companies and also analyzed, among other things, the purchase prices and implied transaction multiples paid in comparable transactions involving target companies in the retail energy and home services businesses, which Merrill Lynch, in its professional judgment, deemed to be relevant.

Finally, with respect to the synfuel tax credits, Merrill Lynch performed discounted cash flow analyses for the period from January 1, 2006 through December 31, 2007, inclusive, using discount rates ranging from 6.5% to 7.5% and no terminal value (because those credits were expected to expire after two years).

The following table reflects the ranges of implied values per share of Constellation common stock calculated by combining the results of these analyses:


	Price Per Share
Sum-of-the-Parts Comparables: No Synergies	$	50.60-$67.23
Sum-of-the-Parts Comparables: With Synergies	$	56.54-$73.17

Each implied per share value of Constellation common stock derived from Merrill Lynch’s sum-of-the-parts selected comparables analyses was compared to the per share value for Constellation implied in the merger of $61.90 and the closing price of Constellation common stock on December 13, 2005 of $56.27 per share.

Sum-of-the-Parts Discounted Cash Flow Analyses

Merrill Lynch performed a sum-of-the-parts analysis to determine the implied equity value of Constellation based on the combined value of its business segments as determined by expected future cash flows of such segments. Based on financial projections provided by Constellation’s management and FPL Group’s management, Merrill Lynch estimated the present value of the unlevered free cash flows that each of Constellation’s business segments were expected to produce over a three-year period. Ranges of terminal values were derived by applying a range of EBITDA multiples to 2008 estimated EBITDA for each Constellation business segment except with respect to Constellation’s synfuel tax credits, for which no terminal value was used because these credits were expected to expire after two years. The free cash flows and terminal values were then discounted to present value using a range of discount rates for each Constellation business segment as follows:


Segment	Time Period	Discount Rate		Exit Multiple
Utility:	3 Years	6.0% – 7.0	%	7.0x – 8.0	x
Merchant Energy:	3 Years	9.0% – 11.0	%	7.0x – 8.0	x
Other Non-regulated:	3 Years	6.5% – 7.5	%	5.0x – 7.0	x
Synfuel Tax Credits:	2 Years	6.5% – 7.5	%	NA

The following table reflects the ranges of implied values per share of Constellation common stock calculated by combining the results of these analyses:


	Price Per Share
Sum-of-the-Parts Discounted Cash Flow: No Synergies	$	52.54-$74.71
Sum-of-the-Parts Discounted Cash Flow: With Synergies	$	58.48-$80.65

Each implied per share value of Constellation common stock derived from Merrill Lynch’s sum-of-the-parts discounted cash flow analyses was compared to the per share value for Constellation implied in the merger of $61.90 and the closing price of Constellation common stock on December 13, 2005 of $56.27 per share.

•

Scana Corp.

Merrill Lynch analyzed the merchant energy segment by analyzing the purchase price and implied transaction multiples paid in transactions involving energy generating assets based on the type of fuel such assets used to generate energy, which Merrill Lynch in its professional judgment, deemed to be relevant. Merrill Lynch reviewed transactions involving facilities that used nuclear, coal, oil, natural gas, hydro, wind, solar, waste coal, pet coke and waste-to-energy power to generate energy, and analyzed the transaction values of such transactions as a multiple of kilowatt of net installed capacity. Merrill Lynch validated the results of its kilowatt of net installed capacity multiple analysis for the merchant energy segment by also performing an analysis of implied multiples of 2006 estimated EBITDA from FPL Group’s merchant energy generation plants.

With respect to FiberNet, Merrill Lynch analyzed, among other things, the purchase prices and implied transaction multiples paid in selected comparable transactions involving target companies in the telecommunications industry, which Merrill Lynch, in its professional judgment, deemed to be relevant.

Pro Forma Merger Analysis

Based on financial projections provided by Constellation’s management and FPL Group’s management, Merrill Lynch analyzed the pro forma impact of the proposed merger on FPL Group’s EPS for the fiscal years ending December 31, 2007 and 2008.

Merrill Lynch’s analysis indicated that, including the expected synergies, the proposed merger would be approximately $0.00 to $0.17 accretive to FPL Group’s EPS for fiscal year ending December 31, 2007 and would be approximately $0.00 to $0.20 accretive to FPL Group’s EPS for fiscal year ending December 31, 2008.

Other Factors

In the course of preparing its opinion, Merrill Lynch also reviewed and considered other information and data, including the following:

•

trading characteristics of Constellation and FPL Group; and

•

historical market prices for Constellation common stock and FPL Group common stock.

Miscellaneous

Pursuant to the terms of Merrill Lynch’s engagement, FPL Group has agreed to pay Merrill Lynch a fee of $22,000,000 payable according to the following schedule: (a) 25% of the fee payable upon public announcement of the merger agreement, (b) 25% of the fee payable upon approval of the merger by the FPL Group shareholders, and (c) the remainder of the fee payable upon the closing of the merger. FPL Group also has agreed to reimburse Merrill Lynch for reasonable expenses incurred by Merrill Lynch in performing its services and to indemnify Merrill Lynch and related persons and entities against liabilities, including liabilities under the U.S. federal securities laws, arising out of Merrill Lynch’s engagement.

Merrill Lynch has, in the past, provided financial advisory and financing services to FPL Group and Constellation and/or their affiliates and may continue to do so. Merrill Lynch has received, and may receive, fees for the rendering of such services. In March 2004, Merrill Lynch acted as lead underwriter with respect to a $300 million offering of Trust Originated Preferred Securities^sm by FPL Capital, a wholly owned subsidiary of FPL Group. In November 2005, Merrill Lynch acted as a lead remarketing agent on a $506 million FPL Capital Series B Debenture remarketing. In addition, in the ordinary course of its business, Merrill Lynch may actively trade Constellation common stock and other securities of Constellation, as well as FPL Group common stock and other securities of FPL Group, for its own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

As described above, Merrill Lynch utilized comparable publicly traded company analysis and comparable transactions analysis to establish a fair trading value of Constellation common stock and FPL Group common stock vis-à-vis the publicly traded companies in the energy, telecommunications and other industries that Merrill Lynch deemed to be comparable to Constellation and FPL Group, respectively. Although similar, none of the selected comparable companies or companies involved in the selected comparable transactions is identical to Constellation or FPL Group. Accordingly, Merrill Lynch believes a complete analysis of the foregoing comparable company analysis and comparable transaction analysis calculations cannot be limited to a quantitative review of the results. Rather, they involve complex considerations and qualitative judgments concerning differences in financial and operating characteristics of the selected comparable companies and companies involved in the selected comparable transactions as well as other factors that could affect the public trading dynamics of the selected comparable companies as well as Constellation and FPL Group.

In conducting its analyses and arriving at its opinions, Merrill Lynch utilized a variety of generally accepted valuation methods. The analyses were prepared solely for the purpose of enabling Merrill Lynch to provide its opinion to the FPL Group board of directors as to the fairness, from a financial point of view, of the exchange

ratio to the holders of FPL Group common stock and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold, which are inherently subject to uncertainty. In connection with its analyses, Merrill Lynch made, and was provided by the management of FPL Group and Constellation with, numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Merrill Lynch, FPL Group or Constellation. Analyses based on estimates or forecasts of future results are not necessarily indicative of actual past or future values or results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of FPL Group, Constellation or their respective advisors, neither FPL Group nor Merrill Lynch nor any other person assumes responsibility if future results or actual values are materially different from these forecasts or assumptions.

FPL Group retained Merrill Lynch based upon Merrill Lynch’s experience and expertise. Merrill Lynch is an internationally recognized investment banking and advisory firm. Merrill Lynch, as part of its investment banking business, is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes.

The terms of the merger were determined through negotiations between Constellation and FPL Group and were approved by the FPL Group board of directors. Although Merrill Lynch provided advice to FPL Group during the course of these negotiations, the decision to enter into the merger was solely that of the FPL Group board of directors. As described above, the opinion and presentation of Merrill Lynch to the FPL Group board of directors were only one of a number of factors taken into consideration by the FPL Group board of directors in making its determination to approve and adopt the merger agreement and the transactions contemplated by the merger agreement, including the merger. Merrill Lynch’s opinion was provided to the FPL Group board of directors to assist it in connection with its consideration of the merger and does not constitute a recommendation to any stockholder as to how to vote or take any other action with respect to the merger. Merrill Lynch’s opinion does not in any manner address the prices at which shares of FPL Group common stock will trade after the announcement of the merger or at which shares of Constellation common stock will trade after the announcement or completion of the merger.

Opinion of Lehman Brothers Inc.

In connection with rendering its opinion, Lehman Brothers performed certain financial, comparative and other analyses described below. Lehman Brothers also relied on these analyses in preparing the presentation made to the FPL Group board of directors. In arriving at its opinion, Lehman Brothers did not ascribe a specific range of value to FPL Group or Constellation but rather made its determination as to the fairness, from a financial point of view, to the shareholders of FPL Group of the exchange ratio, assuming the prior effectiveness of the stock split, to be offered to the shareholders of FPL Group in the merger on the basis of financial and comparative analyses. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances, and therefore, such an opinion is not readily susceptible to summary description. In arriving at its opinion, Lehman Brothers did not attribute any particular weight to any analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Lehman Brothers believes that its analyses must be considered as a whole and that considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. In its analyses, Lehman Brothers made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of FPL Group and Constellation. None of FPL Group, Constellation, Lehman Brothers or any other person assumes any responsibility if future results are materially different from those discussed. Any estimates contained in Lehman Brothers’ analyses were not necessarily indicative of actual values or predictive of future results or values, which may be significantly more

or less favorable than those suggested by its analyses. In addition, analyses relating to the value of the businesses do not purport to be appraisals or to reflect the prices at which businesses actually may be sold.

Based on the terms of the merger agreement, the agreed upon stock split ratio is fixed at 1.444x, and the actual exchange ratio to be offered to FPL Group shareholders is fixed at 1.000x. Lehman Brothers discussed the 1.444x stock split ratio with the FPL Group board of directors and used this stock split ratio as the basis for its opinion as to the fairness of the exchange ratio and its oral presentation to the FPL Group board of directors.

In arriving at its opinion, Lehman Brothers reviewed and analyzed, among other things:

•

the merger agreement and the specific terms of the merger;

•

publicly available information concerning FPL Group and Constellation that Lehman Brothers believed to be relevant to its analysis, including each of their respective Annual Reports on Form 10-K for the fiscal year ended December 31, 2004, Quarterly Reports on Form 10-Q for the quarterly period ended September 30, 2005 and other relevant filings with the SEC;

•

financial and operating information with respect to the business, operations and prospects of FPL Group furnished to Lehman Brothers by FPL Group, including financial projections of FPL Group and extensions of such financial projections, in each case, prepared by FPL Group’s management;

•

financial and operating information with respect to the business, operations and prospects of Constellation furnished to Lehman Brothers by FPL Group, including financial projections of Constellation prepared by the managements of Constellation and FPL Group;

•

trading histories of FPL Group common stock and of Constellation common stock from December 13, 2003 through December 13, 2005 and a comparison of each of their trading histories with each other and with those of other companies that Lehman Brothers deemed relevant;

•

a comparison of the historical financial results and present financial condition of FPL Group and Constellation with each other and with those of other companies that Lehman Brothers deemed relevant;

•

a comparison of the financial terms of the merger with the financial terms of certain other recent transactions that Lehman Brothers deemed relevant;

•

the relative contributions of FPL Group and Constellation to the historical and future financial performance of the combined company on a pro forma basis; and

•

the potential pro forma impact of the merger on the future financial condition and financial performance of FPL Group, including the cost savings, operating synergies and strategic benefits expected to result from the combination of the businesses of FPL Group and Constellation as estimated by the management of FPL Group (which we refer to as the expected synergies in this section “—Opinion of Lehman Brothers Inc.”) and purchase accounting adjustments to the basis of Constellation for reporting purposes under generally accepted accounting principles in the United States as estimated by the management of FPL Group (which we refer to as the purchase accounting adjustments in this section “—Opinion of Lehman Brothers Inc.”).

In addition, Lehman Brothers had discussions with the managements of FPL Group and Constellation concerning their respective businesses, operations, assets, liabilities, financial condition and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate.

In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by Lehman Brothers without assuming any responsibility for independent verification of such information and further relied upon the assurances of the managements of FPL Group and Constellation that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of FPL Group and Constellation, upon advice of FPL Group, Lehman Brothers assumed that such projections were reasonably prepared on a basis reflecting

the best currently available estimates and judgments of the managements of FPL Group and Constellation as to the future financial performance of FPL Group and Constellation, respectively, and that FPL Group and Constellation would perform substantially in accordance with such projections. Lehman Brothers assumed, upon the advice of FPL Group, that the positions in the trading book of the Constellation Energy Commodities Group were accurately reflected in the financial statements of Constellation and the financial impact of such positions as reflected in the financial projections of Constellation would be realized substantially in accordance with such estimates and relied upon such financial statements and projections in performing its analysis. Lehman Brothers also assumed, upon the advice of FPL Group, that the amount and timing of the expected synergies were reasonable and the expected synergies would be realized and purchase accounting adjustments recorded, in each case substantially in accordance with such estimates, and Lehman Brothers relied on the expected synergies and purchase accounting adjustments in performing its analysis. In arriving at its opinion, Lehman Brothers did not conduct a physical inspection of the properties and facilities of FPL Group or Constellation and did not make or obtain any evaluations or appraisals of the assets or liabilities of FPL Group or Constellation. Lehman Brothers further assumed, upon advice of FPL Group, that all material governmental, regulatory or other consents or approvals necessary for the completion of the merger would be obtained within the constraints contemplated by the merger agreement. Lehman Brothers’ opinion necessarily was based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of Lehman Brothers’ opinion.

In addition, Lehman Brothers expressed no opinion as to the prices at which shares of FPL Group common stock or Constellation common stock would trade at any time following the announcement of the merger or Constellation common stock would trade at any time following the completion of the merger.

The following is a summary of the material financial analyses used by Lehman Brothers in connection with providing its opinion to the FPL Group board of directors. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Lehman Brothers, the tables must be read together with the text of each summary.

Comparable Companies Analysis

In order to assess how the public market values shares of comparable publicly traded companies and to provide a range of relative implied equity values per share of FPL Group and Constellation common stock by reference to these companies, which could then be used to calculate implied exchange ratio ranges, Lehman Brothers reviewed and compared specific financial multiples relating to FPL Group and Constellation to corresponding financial ratios for comparable publicly traded utility companies. Lehman Brothers selected these companies based upon its views as to the comparability of the financial and operating characteristics of these companies to FPL Group and Constellation.

The companies included in the comparable companies analysis for FPL Group were:

•

Edison International, Inc.

•

Entergy Corporation

•

PPL Corporation

•

Ameren Corporation

•

The Southern Company

The companies included in the comparable companies analysis for Constellation were:

•

Dominion Resources, Inc.

•

Entergy Corporation

•

Exelon Corporation

•

PPL Corporation

•

Edison International, Inc.

•

Sempra Energy

Lehman Brothers used publicly available research analysts’ estimates to compare specific financial multiples of these companies to FPL Group’s and Constellation’s:

•

stock price to 2006 estimated earnings per share, or EPS;

•

stock price to 2007 estimated EPS;

•

firm value to 2006 estimated EBITDA, where firm value means market equity value as of December 13, 2005 plus the following balance sheet items as of September 30, 2005: debt, minority interest, nonconvertible preferred stock and all out-of-money convertible securities less cash, and where EBITDA means earnings before interest, taxes, depreciation and amortization; and

•

firm value to 2007 estimated EBITDA.

Multiples were based on closing stock prices on December 13, 2005 which was the last day of trading prior to published rumors of a pending transaction between FPL Group and Constellation. The following table reflects the results of the analysis:

Firm Value to EBITDA

Comparable Companies:

Selected Range

FPL Group

7.75x – 8.25

7.50x – 8.00

14.50x – 15.50

13.50x – 14.50

Constellation

7.50x – 8.00

7.25x – 7.75

14.00x – 15.00

12.50x – 13.50

Applying a range of multiples derived from the comparable public companies analysis to corresponding financial data for FPL Group and Constellation provided to Lehman Brothers by FPL Group and Constellation as discussed below, Lehman Brothers calculated a range of implied equity values per share of FPL Group and Constellation common stock which were then used to calculate a range of implied exchange ratios without expected synergies. Then, to determine the impact of synergies, Lehman Brothers assumed that the merger will generate pre-tax annual synergies before integration-related costs by the third year of the combination consistent with FPL Group’s and Constellation’s expectations of $200 million—$250 million of annual synergies. The following table reflects the results of this analysis:


	Comparable Companies Analysis
Implied Exchange Ratio: No Synergies	0.91x – 1.27	x
Implied Exchange Ratio: With Synergies	0.78x – 1.10	x

Lehman Brothers noted that the 1.000x exchange ratio to be offered to the shareholders of FPL Group in the merger, assuming the prior effectiveness of the stock split, fell within the range of the implied exchange ratio, with and without expected synergies, of the comparable companies analysis. However, because of the inherent differences between the business, operations and prospects of FPL Group, Constellation and the companies included in the comparable companies analysis, Lehman Brothers believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the comparable companies analysis and accordingly made and took into consideration qualitative judgments concerning differences between the financial and operating characteristics and prospects of FPL Group, Constellation and the companies included in the comparable companies analysis that would affect the public trading values of each.

Discounted Cash Flow Analysis

In order to estimate the respective present values for FPL Group common stock and Constellation common stock, Lehman Brothers performed discounted cash flow analyses on FPL Group and Constellation using

financial projections for FPL Group provided by FPL Group’s management for the period from January 1, 2006 through December 31, 2008, and financial projections for Constellation prepared by Constellation’s management and provided to Lehman Brothers by FPL Group’s management, for the period from January 1, 2006 through December 31, 2008. Discounted cash flow analysis is a measure designed to provide insight into the value of a company based upon its expected future cash flows.

For the FPL Group discounted cash flow analysis, Lehman Brothers calculated terminal values by applying a range of terminal multiples of 7.75x to 8.25x to FPL Group’s 2008 estimated EBITDA. This range was based on the firm value to 2006 estimated EBITDA multiple range derived in the comparable companies analysis. The cash flow streams and terminal values were discounted to present values using a range of discount rates from 5.18% to 6.18% with a midpoint discount rate of 5.68%. From this analysis, Lehman Brothers calculated a range of implied equity values per share of FPL Group common stock.

For the Constellation discounted cash flow analysis, Lehman Brothers calculated terminal values by applying a range of terminal multiples of 7.50x to 8.00x to Constellation’s 2008 estimated EBITDA. This range was based on the firm value to 2006 estimated EBITDA multiple range derived in the comparable companies analysis. The cash flow streams and terminal values were discounted to present values using a range of discount rates from 5.57% to 6.57% with a midpoint discount rate of 6.07%. From this analysis, Lehman Brothers calculated a range of implied equity values per share of Constellation common stock.

Based on the range of values calculated in the FPL Group and Constellation discounted cash flow analysis with and without expected synergies (net of any estimated costs to achieve such synergies), Lehman Brothers calculated a range of implied equity values per share of FPL Group common stock and Constellation common stock which were then used to calculate a range of implied exchange ratios, with and without expected synergies. The following table reflects the results of this analysis:


	Discounted Cash Flow Analysis
Implied Exchange Ratio: No Synergies	0.84x – 1.22	x
Implied Exchange Ratio: With Synergies	0.71x – 1.06	x

Lehman Brothers noted that the exchange ratio to be offered to the shareholders of FPL Group in the merger, assuming the prior effectiveness of the stock split, fell within the range of the implied exchange ratio, with and without synergies, of the discounted cash flow analysis.

Sum of the Parts Analysis

As one measure of the respective equity values of FPL Group and Constellation and to take into account the value of each companies’ individual business segments, Lehman Brothers performed a “sum of the parts” analysis of FPL Group and Constellation by valuing their respective primary business segments individually and deriving a range of values for each of FPL Group and Constellation as a whole. Lehman Brothers considered the following primary business segments for FPL Group and Constellation:

FPL Group:

•

Florida Power & Light

•

FPL Energy

•

FPL FiberNet

•

Corporate

Constellation:

•

Baltimore Gas and Electric Company

•

Constellation Energy Commodities Group

•

Constellation Generation Group

•

Constellation NewEnergy

•

Other unregulated operations

In the case of Constellation, corporate costs were allocated by segment rather than analyzed separately consistent with Constellation’s financial projections by segment.

Based on the range of values calculated in the FPL Group and Constellation sum of the parts analysis, Lehman Brothers calculated a range of implied equity values per share of FPL Group common stock and Constellation common stock which were then used to calculate a range of implied exchange ratios, assuming the prior effectiveness of the stock split. The following table reflects the results of this analysis:


	Sum of Parts Analysis
Implied Exchange Ratio: No Synergies	0.88x – 1.41	x
Implied Exchange Ratio: With Synergies	0.75x – 1.25	x

Stock Trading History

Lehman Brothers considered historical data with regard to the trading prices of FPL Group common stock and Constellation common stock for the period from December 13, 2004 through December 13, 2005 and the relative stock price performances during the same period of FPL Group, Constellation and certain peer companies of each of FPL Group and Constellation as set forth above in the comparable companies analysis. This historical trading data was reviewed to provide background information and perspective with respect to the relative historical share prices of FPL Group and Constellation. During this period, the closing price of FPL Group common stock ranged from $36.03 to $47.84 per share and the closing price of Constellation common stock ranged from $43.08 to $62.14. Lehman Brothers noted that the price of FPL Group common stock increased approximately 16% and the price of Constellation common stock increased approximately 30% over the period from December 13, 2004 to December 13, 2005.

Historical Exchange Ratio

Lehman Brothers reviewed the ratio of the closing share price of Constellation common stock to the closing share prices of FPL Group common stock on December 13, 2005. Lehman Brothers also reviewed the ratio of the average of daily closing share prices of Constellation common stock to the average of daily closing share prices of FPL Group for the two-year, one-year, six-month, three-month and four-week periods ended December 13, 2005 in order to determine the historical implied average exchange ratios that existed during those periods. The following table reflects the results of the analysis, including the implied premium to Constellation stockholders based on an assumed 1.444x split of Constellation common stock and the corresponding exchange ratio pro forma for a 1.444x split ratio:


Period	0% Premium Split Ratio		Implied Premium to Constellation Stockholders at 1.444x Split Ratio		Exchange Ratio pro forma for 1.444x Split of Constellation Stock
Two-years	1.252	x	15.3	%	1.244	x
One-year	1.295	x	11.5	%	1.186	x
Six-months	1.315	x	9.8	%	1.159	x
Three-months	1.270	x	13.7	%	1.218	x
Four-weeks	1.260	x	14.6	%	1.233	x
December 13, 2005	1.313	x	10.0	%	1.162	x

Lehman Brothers also reviewed the ratio of the average of the twenty day rolling average daily closing share prices of Constellation common stock to the average of the twenty day rolling average daily closing share prices

100

of FPL Group common stock for the period ending on December 13, 2005 and the two-year, one-year, six-month, three-month and four-week periods ended December 13, 2005. A rolling average helps to reduce the effect of any short term price fluctuations. The following table reflects the results of the analysis, including the implied premium to Constellation stockholders based on an assumed 1.444x stock split of Constellation common stock and the corresponding exchange ratio pro forma for a 1.444x stock split ratio:


Period	0% Premium Split Ratio		Implied Premium to Constellation Stockholders at 1.444x Split Ratio		Exchange Ratio pro forma for 1.444x Split of Constellation Stock
Two-years	1.250	x	15.5	%	1.246	x
One-year	1.293	x	11.7	%	1.188	x
Six-months	1.317	x	9.6	%	1.156	x
Three-months	1.280	x	12.8	%	1.205	x
Four-weeks	1.253	x	15.2	%	1.242	x
December 13, 2005	1.261	x	14.5	%	1.232	x

Lehman Brothers noted that the ratios of historical split ratios were below the 1.444x stock split ratio offered to Constellation stockholders. Lehman Brothers also noted that the historical split ratios did not include any premium offered to Constellation stockholders.

Premiums Paid Analysis

To assess the premium deemed to be paid by FPL Group to Constellation stockholders, Lehman Brothers reviewed the premiums paid to stockholders in selected precedent transactions with an equity value greater than $1 billion for (1) all industries announced from 1998 to December 13, 2005 (691 transactions in total) and (2) comparable transactions in the utility sector. The selected comparable historical transactions in the utility sector were the following:

•

Duke Energy Corporation’s proposed acquisition of Cinergy Corp. (announced May 9, 2005)

•

Exelon Corporation’s proposed acquisition of Public Service Enterprise Group Incorporated (announced December 20, 2004)

•

Proposed acquisition of UniSource Energy Corporation by Saguaro Acquisition Corp., a corporation whose indirect owners include investment funds affiliated with J.P. Morgan Partners, LLC, Kohlberg, Kravis, Roberts & Co., L.P., and Wachovia Capital Partners (announced November 2003, terminated December 30, 2004)

•

Energy East Corporation’s acquisition of RGS Energy Group, Inc. (announced February 2001)

•

Potomac Electric Power Company’s merger with Conectiv (announced February 2001)

•

FirstEnergy Corp.’s acquisition of GPU, Inc. (announced August 2000)

•

PECO Energy Company’s merger with Unicom Corp. (announced September 1999)

•

Northern States Power Company’s merger with New Century Energies, Inc. (announced March 1999)

•

American Electric Power Company, Inc.’s merger with Central & South West Corporation (announced December 1997)

Lehman Brothers calculated the premium paid per share by the acquiror in these transactions compared to the share price of the target company one day prior, one week prior and four weeks prior to the selected historical transactions’ respective announcement date. Given the recent nature of the transactions, the premiums for the Exelon Corporation / Public Service Enterprise Group and Duke Energy / Cinergy transactions were specifically reviewed. These premiums were then compared to the implied premium to be paid to Constellation stockholders, based on an assumed 1.0x exchange ratio to FPL Group shareholders immediately after giving effect to a 1.444x split of Constellation common stock, over the price one day prior to, one week prior to, and for the four weeks prior to December 13, 2005. FPL Group was considered the acquiror for purposes of this analysis. The following table reflects the results of the analysis:

101


	Premium to Price Prior to Announcement
	1 Day		1 Week		4 Weeks
Selected Historical Transactions: All Industries	28.4	%	32.3	%	37.8	%
Selected Historical Transactions: Utility Sector	16.7	%	21.0	%	21.6	%
Duke / Cinergy	13.4	%	15.2	%	14.1	%
Exelon / PSEG	8.5	%	16.6	%	17.4	%
Implied Premium in the Merger (as of December 13, 2005)	8.8	%	14.2	%	18.4	%

Lehman Brothers noted that the implied premiums in the merger were lower than the premiums paid in the selected historical transactions, other than the premium paid over the trading price one day prior to announcement in the Exelon / PSEG transaction. In the case of Exelon / PSEG, if December 16, 2004 was selected as the measurement date to account for pre-announcement rumors that increased the stock price of PSEG between December 16, 2004 and the announcement date of December 20, 2004, then the implied premiums in the merger would be lower than the premium paid over the trading price one day prior (14.4%), one week prior (21.1%) and four weeks prior (18.4%) to December 16, 2004 in the Exelon / PSEG transaction.

Contribution Analysis

As one measure of whether the FPL Group shareholders and Constellation stockholders, respectively, are receiving an appropriate portion of the equity ownership of the combined company, Lehman Brothers analyzed the respective contributions of FPL Group and Constellation to projected EBITDA, net income and funds from operations (defined as net income plus depreciation and amortization) for the years 2005 through 2008 without any transaction synergies. Based on the relative contributions of FPL Group and Constellation to the combined company, Lehman Brothers determined a range of implied exchange ratios for FPL Group common stock immediately prior to the effectiveness of the merger, as follows:


	Implied Exchange Ratio Based on Contributions to the Combined Company (No Synergies)
2005E EBITDA	1.04	x
2006E EBITDA	1.09	x
2007E EBITDA	0.88	x
2008E EBITDA	0.80	x
2005E Net Income	1.07	x
2006E Net Income	1.11	x
2007E Net Income	0.94	x
2008E Net Income	1.04	x
2005E Funds from Operations	1.49	x
2006E Funds from Operations	1.35	x
2007E Funds from Operations	1.22	x
2008E Funds from Operations	1.36	x

High	1.49	x
Low	0.80	x

Lehman Brothers noted that the exchange ratio to be offered to the shareholders of FPL Group in the merger fell within the range of the implied exchange ratios of the contribution analysis.

Accretion/Dilution Analysis

In order to evaluate the estimated ongoing impact of the merger, Lehman Brothers analyzed and considered the impact of the merger on the estimated earnings per share of FPL Group for the years 2007 and 2008, using financial projections for FPL Group provided by FPL Group’s management for the period from January 1, 2006 through December 31, 2008 and financial projections for Constellation prepared by the management of Constellation, including expected synergies.

102

Lehman Brothers assumed that, among other things:

•

there would be a 1.0x exchange ratio immediately after giving effect to a 1.444x split of Constellation common stock;

•

FPL Group would be the acquiror for purchase accounting purposes, and any required write-ups and purchase accounting-related adjustments would be in line with those provided by FPL Group;

•

the combined company’s pro forma dividend would be such that FPL Group shareholders would have the same projected dividend as most recently paid by FPL Group with increases that are consistent with past practice taking into account of the proposed exchange ratio;

•

transaction-related costs were treated as one-time items and excluded for accretion/dilution analysis;

•

the merger would be tax-free to both FPL Group shareholders and Constellation stockholders except for any increase in projected dividends to Constellation stockholders; and

•

the merger would close on January 1, 2007.

Based on this analysis, the merger is expected to result in an increase in earnings per share when compared to FPL Group’s earnings per share on a stand-alone basis in the years 2007 and 2008 both with and without expected purchase accounting adjustments.

General

Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The FPL Group board of directors selected Lehman Brothers because of its expertise, reputation and familiarity with FPL Group, Constellation and the utility industry generally and because its investment banking professionals have substantial expertise in transactions comparable to the merger.

As compensation for its services in connection with the merger, FPL Group has agreed to pay Lehman Brothers a fee of $5 million, which was due and payable upon delivery of Lehman Brothers’ fairness opinion on December 18, 2005. FPL Group has also agreed to reimburse Lehman Brothers for certain expenses incurred by Lehman Brothers, including fees of outside legal counsel, and to indemnify Lehman Brothers and related parties against liabilities arising out of Lehman Brothers’ engagement and the rendering of its opinion. Lehman Brothers has performed in the past various investment banking services for FPL Group and Constellation (including financings and advisory services) for which it received customary fees, and Lehman Brothers currently performs and expects to perform in the future various investment banking services for FPL Group and Constellation for which it expects to receive customary fees. In March 2004, Lehman Brothers acted as lead underwriter with respect to a $300 million offering of Trust Originated Preferred Securities by FPL Capital, a wholly owned subsidiary of FPL Group. In November 2005, Lehman Brothers acted as a lead remarketing agent on a $575 million FPL Capital Series A Debenture remarketing. In addition, in January 2006, Lehman Brothers acted as lead manager with respect to a $400 million offering of FPL Group First Mortgage Bonds. In the ordinary course of its business, Lehman Brothers actively trades in the debt or equity securities of FPL Group and Constellation for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in those securities.

Accounting Treatment

The merger will be accounted for under the purchase method of accounting as a reverse acquisition in accordance with GAAP. As a result, FPL Group will be treated as the accounting acquiror and Constellation will be treated as the “acquired” company for financial reporting purposes, and the assets and liabilities of Constellation will be recorded, as of the completion of the merger, at their respective fair values and added to those of FPL Group. The reported financial condition and results of operations of the combined company issued after completion of the merger will reflect Constellation’s balances and results after completion of the merger but will not be restated retroactively to reflect the historical financial position or results of operations of

103

Constellation. Following the completion of the merger, the earnings of the combined company will reflect purchase accounting adjustments, including increased amortization and depreciation expense for acquired assets and assumed liabilities.

Material United States Federal Income Tax Consequences of the Merger

General. This discussion addresses the material United States federal income tax consequences of the automatic conversion of each share of Constellation common stock into 1.444 shares of Constellation common stock in the stock split immediately prior to the completion of the merger and the exchange of shares of FPL Group common stock for shares of Constellation common stock in the merger.

This discussion addresses only holders of Constellation common stock or FPL Group common stock who are “United States persons,” as defined for United States federal income tax purposes. For these purposes a “United States person” is:

•

an individual citizen or resident of the United States;

•

a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is subject to United States federal income taxation regardless of its source; or

•

a trust that (i) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This discussion and the opinions of Kirkland & Ellis LLP, legal counsel to Constellation, and Cravath, Swaine & Moore LLP, legal counsel to FPL Group, that are described in this discussion are or, in the case of the opinions to be delivered upon the completion of the merger, will be based, in part, upon customary written factual representations that have been or, in the case of the opinions to be delivered upon the completion of the merger, will be received from Constellation and FPL Group, which factual representations counsel has assumed to be true, complete and correct and each of which must be accurate as of the effective time of the merger. If any of those assumptions or representations are inaccurate as of the effective time of the merger, the tax consequences of the merger could differ from those described in this joint proxy statement/prospectus.

Neither this discussion nor the opinions of counsel bind the Internal Revenue Service or any court, nor preclude the Internal Revenue Service from adopting a contrary position. The Internal Revenue Service generally will not issue rulings to taxpayers on proposed tax-free transactions unless the Internal Revenue Service determines that a significant issue is involved and must be resolved. No ruling has been or will be sought from the Internal Revenue Service on the tax consequences of the merger or the stock split. This discussion is based on the Internal Revenue Code of 1986, as amended, applicable Treasury regulations, administrative interpretations and court decisions, each as in effect as of the date of this joint proxy statement/prospectus and all of which are subject to change, possibly with retroactive effect. If the Internal Revenue Service were to successfully challenge the “reorganization” status of the merger, the tax consequences would be very different from those set forth above. The tax consequences under foreign laws, United States state and local laws and United States federal laws other than United States federal income tax laws are not addressed.

This discussion addresses only holders of Constellation common stock or FPL Group common stock who hold that common stock as a capital asset and does not address any non-income tax or any foreign, state or local tax consequences of the stock split or the merger. This discussion does not address all aspects of federal income taxation that may be relevant to a holder of that common stock in light of that holder’s particular circumstances or to a holder subject to special rules, such as:

•

a financial institution or insurance company;

104

•

a mutual fund;

•

a tax-exempt organization;

•

a broker or dealer in securities or foreign currencies;

•

a trader in securities that elects to apply a mark-to-market method of accounting;

•

a holder that holds its Constellation common stock or its FPL Group common stock as part of a hedge, appreciated financial position, straddle or conversion transaction; or

•

a holder that acquired its Constellation common stock or its FPL Group common stock pursuant to the exercise of options or otherwise as compensation.

This discussion does not address tax consequences that may vary with, or are contingent on, individual circumstances. Holders of Constellation common stock and FPL Group common stock are urged to consult their tax advisors as to the specific tax consequences to them of the stock split and the merger, including the applicability and effect of federal, state, local and foreign income and other tax laws in light of their particular circumstances.

Federal Income Tax Consequences of the Merger. As a condition to the completion of the merger, each of Kirkland & Ellis LLP, legal counsel to Constellation, and Cravath, Swaine & Moore LLP, legal counsel to FPL Group, will have delivered its opinion, each dated as of the effective time of the merger, that the merger will be treated for federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and that each of Constellation, FPL Group and CF Merger Corporation (the wholly owned subsidiary of Constellation that will merge with and into FPL Group) will be a party to the reorganization within the meaning of Section 368(b) of the Internal Revenue Code. Neither Constellation nor FPL Group intends to waive this condition. In the opinion of Kirkland & Ellis LLP, legal counsel to Constellation, and Cravath, Swaine & Moore LLP, legal counsel to FPL Group:

•

no gain or loss will be recognized by FPL Group, Constellation or CF Merger Corporation in the merger;

•

a holder of FPL Group common stock will not recognize any gain or loss upon the exchange of the holder’s shares of FPL Group common stock for shares of Constellation common stock in the merger;

•

a holder of FPL Group common stock will have a tax basis in the Constellation common stock received in the merger equal to the tax basis of the FPL Group common stock surrendered by the holder in exchange for that Constellation common stock in the merger; and

•

a holder of FPL Group common stock will have a holding period for shares of Constellation common stock received in the merger that includes its holding period for its shares of FPL Group common stock surrendered by the holder in exchange for that Constellation common stock in the merger.

Federal Income Tax Consequences of the Constellation Stock Split. In connection with the completion of the merger, Kirkland & Ellis LLP, legal counsel to Constellation, will have delivered its opinion, dated as of the effective time of the merger, that the automatic conversion of each share of Constellation common stock into 1.444 shares of Constellation common stock in the stock split immediately prior to the completion of the merger will not be a taxable event to the holders of the Constellation common stock, except that gain or loss will be recognized by the holders of the Constellation common stock on the receipt of cash in lieu of a fractional share of Constellation common stock. In the opinion of Kirkland & Ellis LLP, legal counsel to Constellation:

•

the basis of each such 1.444 shares of Constellation common stock to such holders will be equal to the basis of each corresponding share of Constellation common stock in the hands of such holders immediately prior to such automatic conversion, reduced by any tax basis of the Constellation common stock that is allocable to a fractional share of Constellation common stock for which cash is received;

•

the holding period of the new shares as converted will include the holding period for the corresponding shares of Constellation common stock immediately prior to such automatic conversion; and

105

•

to the extent that a holder of Constellation common stock receives cash in lieu of a fractional share of Constellation common stock, the holder will be required to recognize gain or loss equal to the difference between (1) the amount of cash received and (2) the tax basis of the Constellation common stock that is allocable to the fractional share of the Constellation common stock for which cash is received. This gain or loss will be capital gain or loss and will be long-term capital gain or loss if the holding period for the fractional share of Constellation common stock exchanged for cash is more than one year at the time of the automatic conversion.

Backup withholding, currently at 28%, may apply with respect to certain payments such as cash received for fractional shares, unless the holder of the Constellation common stock receiving such payments (1) is an exempt holder (generally, corporations, tax-exempt organizations, qualified pension and profit-sharing trusts, individual retirement accounts, or nonresident aliens who, when required, provide certification as to their status) or (2) provides a certificate containing the holder’s name, address, correct federal taxpayer identification number and a statement that the holder is exempt from backup withholding. A nonexempt holder that fails to provide the required certification may be subject to backup withholding and the withheld amount will be remitted to the Internal Revenue Service as a credit against that holder’s federal income tax liability.

Miscellaneous. Each holder of FPL Group common stock who receives shares of Constellation common stock in the merger and who owned immediately before the merger (i) 5% or more, by vote or value, of the stock of FPL Group or (ii) securities of FPL Group with a tax basis of $1,000,000 or more will be required to file a statement with the shareholder’s federal income tax return for the year of the merger. As provided in Treasury Regulations Section 1.368-3T(b), the statement must set forth the shareholder’s basis in, and the fair market value of, the shares of FPL Group common stock surrendered in the merger, the date of the merger and the name and employer identification number of Constellation, FPL Group and CF Merger Corporation and each such holder is required to retain permanent records of these facts.

Regulatory Matters Relating to the Merger

General

To complete the merger, Constellation and FPL Group need to obtain approvals or consents from, or make filings with a number of United States federal and state public utility, antitrust and other regulatory authorities. The material United States federal and state approvals, consents and filings are described below. The approvals are collectively referred to in this joint proxy statement/prospectus as the “required statutory approvals.”

It is a condition to completion of the merger that “final orders” are obtained for these approvals and that such orders do not impose terms or conditions that (i) would reasonably be expected to have a material adverse effect on (A) the combined company, (B) Constellation or (C) FPL Group and (ii) would reasonably be expected to materially decrease the long-term value of (A) the combined company, (B) Constellation or (C) FPL Group. A “final order” means action by the relevant regulator that has not been reversed, stayed, enjoined, set aside, annulled or suspended, with respect to which any waiting periods before the merger may be completed have expired, and as to which all conditions to the completion of the merger have been satisfied. The merger agreement provides that each party thereto shall cooperate and promptly prepare and file all necessary documentation, applications, notices, petitions and filings and use its reasonable best efforts to obtain necessary approvals and authorizations to effect the merger.

While Constellation and FPL Group believe that they will receive the required statutory approvals and other clearances for the merger, the recently adopted energy legislation in Maryland and the reconstitution of the MPSC have created additional uncertainty and the potential for further delay. There can be no assurance as to the timing of these approvals and clearances or their ability to obtain these approvals and clearances on satisfactory terms or otherwise. There can be no assurance that any of these approvals will be obtained or, if obtained, will not contain terms or conditions that could reasonably be expected to have a material adverse effect on the combined company following completion of the merger. Based on the current status of the regulatory approval process, the parties are working, assuming all other conditions to completion of the merger are satisfied, to complete the merger by the end of 2006 or the first quarter of 2007. In August 2006, the MPSC issued a

106

procedural order indicating that it would be in a position to issue a ruling on the approval of the merger in February 2007. The companies will continue to try to expedite the approval process to complete the merger as soon as practicable. If the parties are unsuccessful in such efforts, or if one or more regulatory agencies in addition to the MPSC conduct hearings or proceedings or otherwise open an investigation, the closing of the merger may not occur until later in 2007. The recently adopted Maryland energy legislation requires the MPSC to conduct proceedings to evaluate the merger pursuant to new standards and procedures.

Each of Constellation and FPL Group currently intend to submit the merger proposals to their respective stockholders at their 2006 annual meetings. It is possible that a governmental agency will not have approved the merger by the date of such annual meetings, which could delay completion of the merger for a significant period of time after Constellation stockholders and FPL Group shareholders have approved the proposals relating to the merger. Any delay in the completion of the merger could diminish the anticipated benefits of the merger or result in additional transaction costs, loss of revenue or other effects associated with uncertainty about the transaction. In addition, it is possible that, among other things, a governmental agency could condition its approval of the merger upon Constellation and FPL Group entering into an agreement to divest a portion of their combined businesses or assets or to restrict the operations of the combined businesses in accordance with specified business conduct rules. See “Risk Factors — The merger is subject to receipt of consent or approval from governmental entities that could delay or prevent the completion of the merger or impose conditions that could have a material adverse effect on the combined company or that could cause abandonment of the merger” beginning on page 24. A governmental agency also could impose significant additional costs on the business of the combined company, including requiring that merger savings be used to reduce rates charged to utility customers. Acceptance of any such conditions could diminish the benefits of the merger to the combined company and result in additional costs, loss of revenue or other effects. Alternatively, rejection of such conditions could result in Constellation and FPL Group litigating with a governmental entity, which could delay the proposed merger or cause the proposed merger to be abandoned.

If stockholders approve the merger proposals at each of the annual meetings before we have received all required regulatory approvals, Constellation and FPL Group may — without seeking further stockholder approval — agree to conditions included in the regulatory approvals subsequently received even if such conditions would have an adverse impact on Constellation, FPL Group or the combined company.

Each of Constellation and FPL Group has agreed to use its reasonable best efforts to take, or cause to be taken, all actions, and to do or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary or advisable to complete and make effective in the most expeditious manner reasonably practicable the merger and the other transactions contemplated by the merger agreement including (i) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging the merger agreement or the completion of the transactions contemplated thereby, and (ii) the execution and delivery of any additional instruments necessary to complete the transactions contemplated by the merger agreement.

As more fully described in “—The Merger Agreement—Termination of Merger Agreement” beginning on page 142, the merger agreement may be terminated by Constellation or FPL Group at any time prior to the completion of the merger if the merger has not been completed by December 31, 2006, provided, however, if the conditions to closing relating to antitrust, other governmental approvals of the merger or the absence of orders, injunctions or laws have not been satisfied, but all other conditions to closing are fulfilled or are capable of being fulfilled as of such date, such date is automatically extended to June 30, 2007. However, a party may not terminate the merger agreement if the cause of the merger not being completed is that party’s failure to fulfill its obligations under the merger agreement.

Antitrust Matters

The merger is subject to review by the Antitrust Division of the United States Department of Justice under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Constellation and FPL Group filed the required notification and report forms with the FTC and the Antitrust Division on February 22, 2006 and received early termination of the statutory waiting period on March 24, 2006. If the merger is not completed by

107

March 24, 2007, Constellation and FPL Group will be required to refile their notification and report forms with the FTC and the Antitrust Division, which would commence a new statutory waiting period.

The grant of early termination does not mean that a federal or state agency or a private party is prevented from challenging the merger under the antitrust laws and seeking to enjoin it or impose conditions such as divestiture of certain assets.

State Approvals

New Maryland Legislation. In June 2006, the Maryland legislature adopted energy legislation that, among other things:

•

reconstitutes the MPSC by dismissing all five of the current MPSC commissioners effective June 30, 2006 and requiring that five new commissioners be selected by the Governor of Maryland from a list prepared by legislative leaders;

•

imposes rate stabilization measures that (i) cap rate increases by BGE for residential POLR service at 15% from July 1, 2006 to May 31, 2007, (ii) give residential POLR customers the option from June 1, 2007 until January 1, 2008 of paying a full market rate or choosing a short term rate stabilization plan in order to provide a smooth transition to market rates without adversely affecting the creditworthiness of BGE, and (iii) provide for full market rates for residential POLR service starting January 1, 2008;

•

allows BGE to recover deferred costs from its customers over a period not to exceed 10 years, on terms and conditions to be determined by the MPSC, including through the issuance of rate stabilization bonds that securitize the deferred costs;

•

directs the MPSC to conduct a comprehensive review of Maryland’s deregulated electricity market, including the implications of requiring or allowing utilities to construct, acquire or lease power generating facilities and alternative approaches to power procurement;

•

directs the MPSC to investigate measures to mitigate the impact of residential rate increases on BGE customers, including by investigating the prior determination of and allowances for stranded costs that occurred when BGE transferred assets to its affiliates in 2000 and by requiring the MPSC to provide funds to residential customers of BGE for mitigation of BGE’s rate increases, including any adjustment in favor of BGE’s customers to allowances for such stranded costs and any funds identified by the MPSC as properly allocated to BGE and its residential customers as conditions to the MPSC’s approval of the merger;

•

expands the authority of the MPSC to review acquisitions, dispositions and financings by public service companies operating in Maryland;

•

requires BGE to credit residential electric rates by approximately $39 million per year for 10 years, beginning January 1, 2007, through suspending the collection of the residential return component of the administrative charge for POLR service and a credit against funds collected from BGE rate payers for the nuclear decommissioning trust for Constellation’s Calvert Cliffs nuclear plant;

•

directs Maryland’s taxing authority to consider whether property tax valuation methodologies applied to power plants located in Maryland should be revised in light of the values of those properties in a restructured electric industry; and

•

directs the MPSC to conduct a full review of the merger pursuant to new standards and procedures and include certain conditions in any order approving the merger as discussed below.

Because the legislation requires substantial additional decisions and proceedings by the MPSC and other governmental authorities to implement many of its provisions, Constellation and FPL Group cannot predict the impact of the legislation on Constellation, the combined company, the energy market in Maryland or the merger. The new legislation and its implementation through applicable regulatory proceedings could have a material adverse effect on the business and financial results of Constellation and the combined company. In addition, certain current MPSC commissioners have challenged in court the provisions requiring appointment of a new group of commissioners, and one or more parties may challenge the constitutionality of one or more provisions of the new legislation. The outcome of any challenges and the additional uncertainty that could result cannot be predicted.

108

Maryland Public Service Commission. Under recently enacted legislation in Maryland, the merger is subject to the approval of the MPSC, which is required to promptly and comprehensively review and take action on the merger. The new law provides that the MPSC shall issue an order approving the merger if it finds that the merger “is consistent with the public interest, convenience, and necessity, including benefits and no harm to consumers.” The legislation requires that the MPSC include, in any order approving the merger, the following conditions:

•

the merger does not provide for the transfer of any facilities between Florida Power & Light or BGE and an “associate company”;

•

the merger does not provide for the new issuance of securities by Florida Power & Light or BGE for the benefit of an associate company;

•

the merger does not provide for new pledges or encumbrances of assets of Florida Power & Light or BGE for the benefit of an associate company;

•

the merger does not provide for new affiliate contracts between nonutility associate companies and Florida Power & Light or BGE, other than for goods and services that are subject to FERC review under Sections 205 and 206 of the Federal Power Act; and

•

any savings from the merger must be applied in part to “the elimination of carrying charges and the delay of increases” in residential electric rates for BGE customers.

On July 21, 2006, Constellation and FPL Group filed a new application for approval with the MPSC that addresses the standards and application requirements of the new legislation. Because certain current MPSC commissioners have challenged in court provisions of the new legislation requiring appointment of a new group of commissioners, because new commissioners may be appointed to the MPSC and because the legislation requires the MPSC to consider a substantial number of important matters in addition to the merger (such as BGE’s rate stabilization arrangements), the timing and scope of any proceedings relating to the merger and the timing of MPSC action on the merger is uncertain. There is no assurance that approval will be granted or that the conditions of any approval, if received, will be satisfactory to either Constellation or FPL Group, or both of them.

Florida Public Service Commission. While the FPSC does not have jurisdiction to approve the merger of electric utilities, under chapter 366 of the Florida Statutes, the FPSC has broad authority over the rates, charges and reliability of Florida Power & Light as a public utility under Florida law and may elect to review the impact of the merger, whether in the near term or in a future ratemaking or other proceeding. The FPSC has intervened in FPL Group’s and Constellation’s merger proceedings with FERC.

New Hampshire Public Utility Commission. Florida Power & Light owns a substation at the FPL Energy Seabrook, LLC nuclear facility (the “Seabrook Substation”) located in Seabrook, New Hampshire. As a condition of owning and operating the Seabrook Substation, Florida Power & Light became a public utility in New Hampshire. Under New Hampshire law, approval of the New Hampshire Public Utilities Commission (which we refer to herein as the NHPUC) is not required if the merger will not have an adverse effect on rates, terms, service or operation of Florida Power & Light within the state. On February 17, 2006, FPL Group and Constellation filed a joint application with the NHPUC in support of a finding that the transaction will not have an adverse effect on rates, terms, service or operation of Florida Power & Light within the state and an alternative request for approval of the merger. On April 18, 2006, the NHPUC issued a letter accepting FPL Group and Constellation’s representation that the proposed merger will not adversely affect rates, terms, service, or operations of any New Hampshire public utility. Thus, no further action by the NHPUC is required.

New Jersey Department of Environmental Protection. FPL Group, through its subsidiaries, has an interest in a plant and property in New Jersey that is subject to the New Jersey Industrial Site Recovery Act (which we refer to herein as ISRA). On February 9, 2006, FPL Group filed for a declaratory ruling from the New Jersey Department of Environmental Protection (which we refer to herein as the NJDEP) that ISRA does not apply to the merger. On March 6, 2006, the NJDEP issued a response confirming that the merger is not subject to the provisions of ISRA as there is no change of control of the facility with FPL Group.

109

New York Public Service Commission. As owners of generation facilities in the State of New York, subsidiaries of FPL Group and Constellation are subject to the jurisdiction of the New York Public Service Commission (which we refer to herein as the NYPSC). Under Section 70 of the New York Public Service Law, the NYPSC’s declaratory ruling of exemption or, alternatively, its approval, is required in connection with the indirect transfer of ownership interests in such subsidiaries in connection with the merger. The NYPSC approved the transfer on July 25, 2006.

Public Utility Commission of Texas. The Public Utility Commission of Texas (which we refer to herein as PUCT) is authorized by Sections 39.158 and 39.154 of the Texas Public Utility Regulatory Act to independently review proposals to merge or consolidate electric generation facilities that offer electricity for sale in Texas. PUCT will approve the proposed transaction if the combining owners’ generating capacity operating in the Electric Reliability Council of Texas (which we refer to herein as ERCOT) is less than 20% of ERCOT’s total capacity. The combined capacity of FPL Group and Constellation operating in ERCOT is approximately 5,076 MW, or approximately 6.25% of ERCOT’s total capacity. On February 6, 2006, FPL Group and Constellation and their subsidiaries that own and/or operate electric generation facilities in Texas jointly filed an application requesting PUCT’s approval of the merger based on a determination that the 20% threshold is not exceeded. The PUCT approved the merger on June 29, 2006.

Nuclear Regulatory Commission

Florida Power & Light holds certain NRC operating licenses for its Turkey Point and St. Lucie nuclear generating facilities. An indirect subsidiary of FPL Energy holds an NRC operating license for the Seabrook Station nuclear generating facility. Another indirect subsidiary of FPL Energy holds an NRC operating license for the Duane Arnold Energy Center nuclear generating facility. The NRC licenses authorize Florida Power & Light and the indirect subsidiaries of FPL Energy to own and/or operate their nuclear generating facilities.

Constellation, through its various subsidiaries, holds six relevant NRC licenses for its three nuclear facilities—Calvert Cliffs, Nine Mile Point and Ginna. Constellation is the sole owner of these facilities, with the exception of Nine Mile Point, Unit 2. Constellation owns 82% of that unit and The Long Island Power Authority owns the remaining 18%.

The Atomic Energy Act of 1954, as amended, provides that a NRC license may not be transferred or, in any manner disposed of, directly or indirectly, through a transfer of control of any license unless the NRC finds that the transfer complies with the Atomic Energy Act and consents to the transfer. Therefore, the consent of the NRC may be required for the indirect transfer of control pursuant to the merger of the licenses held by the parties. On January 23, 2006, Constellation requested a threshold determination by the NRC that the NRC’s consent is not required because the merger does not involve the transfer of any of the licenses for the Constellation nuclear facilities, along with an application requesting consent to the transfer should the NRC determine such consent is required. The threshold determination request was denied by the NRC. In addition, on January 23, 2006, Florida Power & Light and the two indirect subsidiaries of FPL Energy jointly filed an application requesting that the NRC consent to the transfers of the licenses for their respective nuclear facilities. On August 3, 2006, the NRC granted consent to the transfers.

Federal Communications Commission

The parties own certain business radio licenses issued by the FCC. FCC approval is required prior to the transfer of control of any entity holding such FCC licenses. The FCC will review whether the transfer of control of such entity and licenses is in the public interest. In March 2006, Constellation filed applications with the FCC and the FCC issued its approvals, which expire in September 2006. In August 2006, Constellation filed a request to extend the approvals through March 2007 and is awaiting a response from the FCC.

110

Federal Energy Regulatory Commission

Each of Constellation and FPL Group has public utility subsidiaries subject to the jurisdiction of FERC under the Federal Power Act. Section 203 of the Federal Power Act provides that no holding company in a holding company system that includes a transmitting utility or an electric utility may merge or consolidate with a holding company system that includes a transmitting utility or electric utility company without first having obtained authorization from FERC.

FERC must approve the merger if it finds that the transaction is consistent with the public interest. FERC has stated in its 1996 utility merger policy statement that, in analyzing a merger under Section 203, it will evaluate the following criteria:

•

the effect of the merger on competition in wholesale electric power markets, utilizing an initial screening approach derived from the Department of Justice/Federal Trade Commission-Initial Merger Guidelines to determine if a merger will result in an increase in an applicant’s market power;

•

the effect of the merger on the applicants’ FERC jurisdictional ratepayers; and

•

the effect of the merger on state and federal regulation of the applicants.

In addition, in accordance with the Energy Power Act of 2005, FERC must also find that the transaction will not result in the cross-subsidization by public utility subsidiaries of other subsidiaries or improper encumbrances or pledges of utility assets and, if such cross-subsidization or encumbrances were to occur, whether they are in the public interest.

On February 9, 2006, Constellation and FPL Group made the initial filing of their application for approval with FERC. Constellation and FPL Group currently expect that the FERC schedule relating to approval under Section 203 will not impact the anticipated timing of closing of the merger.

As part of the application, both Constellation and FPL Group committed that they will not seek to include merger-related costs in their wholesale rates or filed transmission revenue requirements for a period of five years after the merger is completed unless there are off-setting merger-related savings equal to or in excess of such merger-related costs. In addition, Constellation and FPL Group have stated to FERC that the merger will not result in the cross-subsidization of their unregulated businesses by their regulated utility businesses or the pledge or encumbrance of utility assets for the benefit of their unregulated businesses. Nevertheless, Constellation and FPL Group have agreed to a hold harmless commitment to protect captive wholesale and transmission customers from any adverse rate effects that could result from any such cross-subsidization, pledge or encumbrance for a period of five years following the completion of the merger.

On July 13, 2006, FERC issued a tolling order giving it an additional 180 days to consider the application. Had FERC not issued the tolling order, it would have been required to issue a ruling by August 8, 2006. FERC now has until February 2, 2007 to issue a ruling.

Other Approvals

The merger may also be subject to review by the governmental authorities of various other jurisdictions under the antitrust and utility regulation laws of those jurisdictions. Constellation and FPL Group do not expect that any of these reviews will impact the anticipated timing of the closing of the merger.

There can be no assurance that the reviewing authorities will permit the applicable statutory waiting periods to expire or that the reviewing authorities will terminate the applicable statutory waiting periods at all or otherwise approve the merger without restrictions or conditions that would have a material adverse effect on the combined company if the merger were completed. These restrictions and conditions could include mandatory licenses, sales or other dispositions of assets, divestitures, or the holding separate of assets, businesses or FPL Group capital stock or implementation of adverse rate or operating conditions.

111

Appraisal Rights

Holders of Constellation common stock and FPL Group common stock do not have appraisal rights under Maryland or Florida law in connection with the merger.

Federal Securities Laws Consequences; Stock Transfer Restriction Agreements

This registration statement of which this joint proxy statement/prospectus is a part does not cover any resales of the Constellation common stock to be received by the shareholders of FPL Group upon completion of the merger, and no person is authorized to make any use of this joint proxy statement/prospectus in connection with any such resale.

All shares of Constellation common stock received by FPL Group shareholders pursuant to the merger will be freely transferable, except that shares of Constellation common stock received by persons who are deemed to be “affiliates” of FPL Group under the Securities Act of 1933 at the time of the FPL Group annual meeting may be resold by them only in transactions permitted by Rule 145 under the Securities Act of 1933 or as otherwise permitted under the Securities Act of 1933. Persons who may be deemed to be affiliates of FPL Group for such purposes generally include individuals or entities that control, are controlled by or are under common control with, FPL Group, as the case may be, and include directors and certain executive officers of FPL Group. The merger agreement requires that FPL Group use reasonable best efforts to cause each affiliate to execute a written agreement which provides that such persons will not offer, sell or otherwise dispose of any of the shares of Constellation common stock issued to them pursuant to the merger in violation of the Securities Act of 1933 or the related SEC rules and regulations promulgated thereunder.

Stock Exchange Listing; Delisting and Deregistration of FPL Group Common Stock

It is a condition to the merger that the shares of Constellation common stock issuable pursuant to the merger be approved for listing on the NYSE, subject to official notice of issuance. Shares of Constellation common stock will continue to be traded on the NYSE under the symbol “CEG” immediately following the completion of the merger. If the merger is completed, FPL Group common stock will cease to be listed on the NYSE and its shares will be deregistered under the Securities Exchange Act of 1934.

Business Relationships between FPL Group and Constellation

In the ordinary course of business during the three years ended December 31, 2005 and during 2006, FPL Group and Constellation have purchased and sold power and natural gas from each other and BGE has provided post-hurricane assistance to FPL Group. In addition, FPL Group and Constellation each hold partnership interests in limited partnerships related to solar energy.

112

ADDITIONAL INTERESTS OF FPL GROUP’S AND CONSTELLATION’S DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER

Stockholders should note that some FPL Group and Constellation directors and executive officers have interests in the merger as directors or executive officers that are in addition to, and may be different from, the interests of other FPL Group shareholders and Constellation stockholders.

Positions with the Combined Company

As provided in the merger agreement, at the completion of the merger, the Constellation board of directors will be composed of nine persons who served as FPL Group directors prior to the merger and six persons who served as Constellation directors prior to the merger. The merger agreement also provides that Lewis Hay, III, the current Chairman, President and Chief Executive Officer of FPL Group, will become Chief Executive Officer of Constellation, and that Mayo A. Shattuck III, the current Chairman, President and Chief Executive Officer of Constellation, will remain Chairman of the Constellation board of directors. In addition, following the merger, James L. Robo, who is currently the Vice President, Corporate Development and Strategy of FPL Group and the President of FPL Energy, will oversee the combined company’s generation operations and its utilities, E. Follin Smith will continue in her role as Constellation’s Chief Financial Officer and Chief Administrative Officer, Armando Olivera will continue in his role as President of Florida Power & Light, Kenneth W. DeFontes, Jr. will continue in his role as President and Chief Executive Officer of BGE, Thomas V. Brooks will continue in his role as Chairman of CCG, and Moray P. Dewhurst, who is currently the Vice President, Finance and Chief Financial Officer of FPL Group, will oversee transition and integration of FPL Group and Constellation.

Additional Interests of FPL Group’s Directors and Executive Officers in the Merger

Executive Retention Employment Agreements

Each of Lewis Hay, III, Moray P. Dewhurst, Robert H. Escoto, Robert L. McGrath, Armando J. Olivera, James L. Robo, Antonio Rodriguez, John A. Stall and Edward F. Tancer is a party to an executive retention employment agreement with FPL Group. Under the original terms of the executive retention employment agreements, if the merger resulted in a “change in control” (as defined in the agreements), each executive officer would have become entitled to guaranteed employment terms when the merger agreement was executed and would have become entitled to payments automatically upon completion of the merger and other payments if his employment was terminated without cause or if he resigned for good reason prior to the second or third anniversary of the merger. However, effective as of the date of the merger agreement, all of the executive retention employment agreements were amended to provide that none of (a) the execution of the merger agreement, (b) the approval of the merger agreement by the FPL Group shareholders or (c) the completion of the merger will constitute a change in control or a potential change in control for purposes of the agreements. In the case of Mr. Hay, the amendment to his executive retention employment agreement cannot be rescinded. Accordingly, Mr. Hay will not become entitled to any payments or benefits under his executive retention employment agreement in connection with the merger. Each other executive officer will only become entitled to payments and benefits under his executive retention employment agreement as a result of the merger if (a) the merger would have resulted in a change in control under his executive retention employment agreement in the absence of the amendment, (b) the executive officer becomes entitled to rescind the amendment and (c) he exercises the right to rescind.

In the absence of the amendments, a change in control would occur as a result of the merger under the executive retention employment agreements with Messrs. Hay, Dewhurst, Olivera, Robo, Rodriguez and Stall if FPL Group common stock outstanding immediately prior to the merger (as converted pursuant to the merger) does not represent more than 60% of the common stock and other voting securities (if any) entitled to vote in the election of directors of the combined company immediately following the merger. For purposes of the executive retention employment agreements with Messrs. Escoto, McGrath and Tancer, in the absence of the amendments,

113

a change in control would occur as a result of the merger if FPL Group common stock outstanding immediately prior to the merger (as converted pursuant to the merger) does not represent more than 55% of the common stock and other voting securities (if any) entitled to vote in the election of directors of Constellation immediately following the merger. Based upon the number of outstanding shares of Constellation common stock and FPL Group common stock as of the date of this joint proxy statement/prospectus, FPL Group common stock outstanding immediately prior to the merger (as converted pursuant to the merger) is expected to represent approximately 60% of the common stock and voting securities entitled to vote in the election of directors of the combined company immediately following the merger (and there are expected to be no other voting securities). The precise percentages will depend upon the number of new shares issued through the date of completion of the merger by each of Constellation and FPL Group, as permitted by the merger agreement. Accordingly, the merger may constitute a change in control under the agreements with Messrs. Hay, Dewhurst, Olivera, Robo, Rodriguez and Stall but is not expected to constitute a change in control under the agreements with Messrs. Escoto, McGrath and Tancer.

The amendments to the executive retention employment agreements provide that each executive officer (other than Mr. Hay) may rescind his amendment if, at any time prior to the second anniversary (for Messrs. Rodriguez and Stall) or third anniversary (for Messrs. Escoto, McGrath, Olivera, Robo and Tancer) of the completion of the merger, (a) his employment is terminated without “cause” (as defined in the amendment), (b) his base salary, annual target bonus opportunity or annual long-term incentive opportunity is reduced from the levels in effect on the date of the merger agreement, (c) he is required to relocate 20 miles or more from his place of employment as of the date of the merger agreement, (d) Mr. Hay ceases (for any reason, including his resignation) to serve as Chief Executive Officer of FPL Group prior to the completion of the merger or Chief Executive Officer of Constellation following the merger, (e) the executive officer is assigned duties or responsibilities that are a material diminishment of those in effect on the date of the merger agreement or (f) there is a material diminution or adverse change in his duties, responsibilities or reporting requirements from those in effect immediately following the merger. Mr. Dewhurst’s amendment may be rescinded as a result of the occurrence of the events described in clauses (a) through (d) of the preceding sentence prior to the third anniversary of the merger, but instead of having the right to rescind as a result of the occurrence of one of the events described in clause (e) or (f), Mr. Dewhurst will have the right to rescind if, as of the one-year anniversary of the merger, there is a material diminution or adverse change to his titles, duties, responsibilities or reporting requirements from those in effect on the date of the merger agreement. Notwithstanding any rights of an executive officer to rescind his amendment, the executive officer will only be entitled to payments and benefits under his executive retention employment agreement if the merger would have constituted a change in control under his executive retention employment agreement in the absence of the amendment.

Although the merger is not expected to result in a change in control pursuant to the terms of FPL Group’s long-term incentive plan, certain executive officers could nevertheless become entitled to accelerated vesting of incentive awards granted under FPL Group’s long-term incentive plan pursuant to their executive retention employment agreements. In the event that the merger would have constituted a change in control under the executive retention employment agreements with Messrs. Dewhurst, Olivera, Robo, Rodriguez or Stall and any such executive officer validly rescinds his amendment, regardless of whether or not his employment terminates, he will become automatically entitled to accelerated vesting of certain incentive awards (including accelerated vesting of 100% of unvested stock options and non-performance stock-based awards, with the exception of certain awards granted effective in February 2006 to Messrs. Dewhurst and Robo that will not accelerate, and 50% of unvested performance stock-based awards) that were granted to him prior to completion of the merger. The following table sets forth for each of Messrs. Dewhurst, Olivera, Robo, Rodriguez and Stall the amount that such individual would receive in respect of incentive awards that are currently outstanding and will be unvested on the date of completion of the merger, assuming the completion of the merger occurs on December 31, 2006 and that such individual becomes entitled to rescind and validly rescinds the amendment to his executive retention employment agreement immediately thereafter. Amounts are based on a price of FPL Group common stock of $40.87 and calculated assuming all awards are exercised and all underlying shares are sold. Actual amounts may be higher or lower depending on the value of Constellation common stock on the date any

114

accelerated vesting is triggered and the number of incentive awards that are unvested on the date any accelerated vesting is triggered.


Executive Officer	Cash that would be paid if unvested awards were accelerated and cashed out
Mr. M. Dewhurst	$	3,270,400
Mr. A. Olivera	$	3,226,300
Mr. J. Robo	$	3,223,900
Mr. A. Rodriguez	$	1,591,300
Mr. J. Stall	$	2,693,700

For a description of the conversion of FPL Group long-term incentive awards into Constellation long-term incentive awards, see the section “Treatment of FPL Group Long-Term Incentive Plan Awards” beginning on page 117.

If the merger would have constituted a change in control under the executive retention employment agreements with Messrs. Dewhurst, Olivera, Robo, Rodriguez or Stall and any such executive officer becomes entitled to rescind and validly rescinds the amendment and his employment is terminated without “cause” or he terminates his employment for “good reason” (as such terms are defined in the agreements), prior to the second anniversary (for Messrs. Rodriguez and Stall) or third anniversary (for Messrs. Dewhurst, Olivera and Robo) of the completion of the merger, such executive officer will become entitled to the following additional benefits:

•

a lump-sum cash payment equal to a pro rata portion of the executive’s annual bonus;

•

a lump-sum cash payment equal to two times (for Messrs. Rodriguez and Stall) or three times (for Messrs. Dewhurst, Olivera and Robo) the sum of his then-current annual base salary and annual bonus;

•

a lump-sum cash payment in respect of enhanced supplemental retirement benefits (including matching contributions), assuming two additional years of service credit (for Messrs. Rodriguez and Stall) or three additional years of service credit (for Messrs. Dewhurst, Olivera and Robo);

•

accelerated vesting of the second 50% of unvested performance stock-based awards granted prior to the merger that did not accelerate automatically upon rescission of the amendment;

•

accelerated vesting of a pro rata portion of incentive awards granted upon or following completion of the merger (including stock options and other stock-based awards), assuming continued employment for two years (for Messrs. Rodriguez and Stall) or three years (for Messrs. Dewhurst, Olivera and Robo) following the merger;

•

continued welfare and fringe benefits for specified periods; and

•

continued social and business club memberships, use of a company car, personal financial planning and other perquisites for specified periods or a lump-sum cash payment equal to the value of benefits, if elected by the executive officer.

115

The following table sets forth the estimated value of such payments and benefits based on compensation and benefit levels in effect on the date of this joint proxy statement/prospectus, and assuming the completion of the merger occurs on December 31, 2006, and that such individual becomes entitled to rescind and validly rescinds his amendment and is terminated by Constellation without “cause” or resigns for “good reason” immediately thereafter. Such amounts do not include amounts payable in respect of incentive awards granted following the completion of the merger or distribution of vested benefits under any benefit plan or agreement.


Executive Officer	Cash severance ⁽¹⁾		Value of accelerated vesting (if any) and enhancement of supplemental retirement plan benefits			Cash that would be paid if the second 50% of performance stock-based awards granted prior to completion of merger are accelerated and cashed out		Value of other benefits
Mr. M. Dewhurst	$	3,668,500	$	1,180,600		$	1,416,500	$	209,000
Mr. A. Olivera	$	3,998,100	$	2,579,000		$	1,331,500	$	232,900
Mr. J. Robo	$	4,320,900	$	1,413,900	(2)	$	1,410,800	$	226,900
Mr. A. Rodriguez	$	1,384,100	$	1,465,800		$	670,800	$	196,400
Mr. J. Stall	$	2,166,300	$	694,400		$	1,031,100	$	190,000

Notes:

(1)	Includes bonus and severance equal to two or three times (as applicable) the sum of the executive’s then current annual base salary and annual bonus.

(2)

Includes $412,400 for Mr. Robo, which is the value of the accelerated vesting of his unvested benefits under the supplemental executive retirement plan. Pursuant to the plan, following a change in control, if a participant’s employment is terminated as a result of the change in control, all benefits accrued by the participant under the plan will fully vest.

Although the executive retention employment agreements provide for a gross-up in respect of any golden parachute excise taxes imposed on an executive officer, the merger will not result in the imposition of golden parachute excise taxes on payments to FPL Group’s executive officers because FPL Group will not experience a change in control for purposes of the golden parachute rules. Accordingly, no gross-up payments will be made to any FPL Group executive officers.

Employment Agreement with Mr. Hay

In addition to the executive retention employment agreement with Mr. Hay, FPL Group is also a party to an employment agreement with Mr. Hay that currently governs the terms and conditions of his employment. Effective as of the date of the merger agreement, the employment agreement was amended to provide that the employer for purposes of the agreement would include Constellation following the merger.

Pursuant to his employment agreement, upon completion of the merger, Mr. Hay will become entitled to terminate his employment for “good reason” (as defined in his employment agreement) and receive benefits and payments under his employment agreement because he will not be the Chairman of Constellation immediately following the merger. Mr. Hay is not expected to exercise this right at the time of the completion of the merger but reserves the right to do so. If Mr. Hay does elect to terminate his employment for “good reason” or if his employment is terminated involuntarily without “cause” (as defined in his employment agreement), Mr. Hay will be entitled to receive the following termination benefits under his employment agreement:

•

payment of a pro rata portion of Mr. Hay’s annual incentive bonus at the higher of (i) Mr. Hay’s average annual incentive bonus for the prior two years, or (ii) the target annual bonus for the year in which termination occurs;

•

an amount equal to two times the sum of Mr. Hay’s annual base salary and annual incentive bonus, determined as described in the preceding bullet point;

116

•

payment of a pro rata portion of each outstanding and unvested performance share grant under the long-term incentive plan, assuming that target performance was achieved;

•

continued vesting of any restricted stock and stock options outstanding under the long-term incentive plans for a period of two years following termination;

•

continued welfare benefit plan participation for specified periods; and

•

payment of the cash value of two additional years of service credit under all applicable pension, 401(k), SERP and supplemental SERP plans.

Assuming that the completion of the merger occurs on December 31, 2006 and that Mr. Hay’s employment is terminated involuntarily without “cause” or he resigns for “good reason” immediately thereafter, the value of the payments due to Mr. Hay (not including amounts payable in respect of outstanding grants under FPL Group’s long-term incentive plan or distribution of vested benefits under any benefit plan or agreement) would be approximately $9,085,700 based on Mr. Hay’s compensation and benefit levels in effect on the date of this joint proxy statement/prospectus, and the amount that Mr. Hay would receive in respect of performance share awards that he currently holds, assuming all underlying shares are sold, based on a price of FPL Group common stock of $40.87, would be $6,625,500. The actual amount of the payment in respect of performance share awards may be higher or lower depending on the value of Constellation common stock on the date of termination of employment. In addition, the estimated value of the unvested stock options and restricted stock held by Mr. Hay on December 31, 2006 that would continue to vest during the two-year period following Mr. Hay’s termination of employment, assuming that the price of FPL Group common stock (as converted into Constellation common stock pursuant to the merger) remains at $40.87 per share throughout such two-year period and that all stock options are exercised and all shares are sold immediately upon vesting, would be $6,301,500. Actual amounts of any payments in respect of stock options and restricted stock may be higher or lower depending on the value of Constellation common stock on the date of vesting or exercise. In addition, estimated amounts in respect of performance share awards, stock options and restricted stock do not reflect any value that may be paid in connection with awards granted to Mr. Hay after the date of this joint proxy statement/prospectus.

For a description of the amendments to be made to Mr. Hay’s employment agreement prior to completion of the merger in order to reflect Mr. Hay’s role and duties with Constellation, as set forth in the merger agreement, see the section “Post Merger Governance and Management—Other Board of Directors Matters—Appointment and Removal of Officers” beginning on page 149.

Treatment of FPL Group Long-Term Incentive Plan Awards

Stock Options. On the closing of the merger, each outstanding stock option to purchase FPL Group common stock granted pursuant to the FPL Group Amended and Restated Long-Term Incentive Plan, the Gexa Corporation 2002 Non-Employee Director Option Plan and the Gexa Corporation Amended and Restated 2004 Incentive Plan (such plans, together with the FPL Group Non Employee Directors Stock Plan, the “FPL Group Stock Plans”) will be converted into an option to purchase Constellation common stock. The number of shares of Constellation common stock underlying the new Constellation option will, subject to the prior effectiveness of the stock split, equal the number of shares of FPL Group common stock that were subject to the FPL Group stock option at an exercise price per share equal to the exercise price of the FPL Group stock option on the same terms and conditions, including vesting, as were applicable to the FPL Group stock option.

Restricted Stock. Each share of FPL Group restricted stock issued pursuant to the FPL Group Stock Plans shall be converted on the closing of the merger, subject to the prior effectiveness of the stock split, into one share of Constellation restricted stock, on the same terms and conditions, including vesting, as were applicable to such share of FPL Group restricted stock prior to the merger.

Other Equity-Based Awards. All outstanding FPL Group other equity based awards, including performance share awards, shall be amended and converted on the closing of the merger, subject to the prior effectiveness of

117

the stock split, into an equity or equity-based award in respect of a number of shares of Constellation common stock equal to the number of shares of FPL Group common stock subject to such FPL Group other equity-based award on the same terms and conditions, including vesting, as were applicable to such FPL Group other equity based award.

For information regarding certain awards with respect to FPL Group’s common stock held by each of FPL Group’s named executive officers, see “Other Matters to be Considered at the Annual Meeting—FPL Group Proposal 2: Election of Directors” beginning on page 189.

FPL Group Deferred Compensation and Supplemental Executive Retirement Plan

In the event that the merger constitutes a change in control under FPL Group’s deferred compensation plan, and if a participant in the plan is terminated as a result of the change in control, all amounts deferred by that participant will become payable in a single lump sum on the first day of the month following the termination of employment subsequent to the merger. Under the deferred compensation plan, a change in control will occur if FPL Group common stock outstanding immediately prior to the merger (as converted pursuant to the merger) does not represent more than 60% of the common stock and other voting securities (if any) entitled to vote in the election of directors of the combined company immediately following the merger. Accordingly, the merger may constitute a change in control under the deferred compensation plan.

The approval of the merger agreement by the FPL Group shareholders will constitute a change in control under FPL Group’s supplemental executive retirement plan. Accordingly, if a participant in the plan is terminated as a result of the change in control, all benefits accrued under the plan by that participant will vest and payment of benefits will be made either in a lump sum within three months following the participant’s termination of employment or in accordance with the form of distribution selected by the participant under FPL Group’s tax-qualified pension plan, as determined by the terminated participant.

In the event of a change in control under the deferred compensation plan and the supplemental executive retirement plan, the grantor trusts that secure benefits under the plans will become irrevocable and cannot be amended and a reversion of excess trust assets cannot be taken. Such trusts are currently not funded in excess of plan liabilities.

Mr. Robo is the only executive officer of FPL Group who has benefits under the FPL Group supplemental executive retirement plan that were not fully vested as of the date of this joint proxy statement/prospectus. The value of the accelerated vesting of his benefits is included in the table beginning on page 116 in “Executive Retention Employment Agreements” under the column entitled “Value of accelerated vesting (if any) and enhancement of supplemental retirement plan benefits.” All other executive officers who participate in the FPL Group supplemental executive retirement plan are fully vested in their benefits under the plan.

FPL Group Retention Bonus Program

Effective as of the date of the merger agreement, FPL Group established an employee retention bonus plan to provide certain employees of FPL Group and its affiliates with an incentive to remain in the employment of FPL Group or an affiliate (including Constellation) through and after the merger. The aggregate amount that may be paid to all participants in the plan is $70 million. Under the plan, participants may become entitled to bonuses in amounts ranging from one-half times base pay to two times the sum of base pay and average annual incentive compensation. A participant will generally be entitled to 50% of his or her retention bonus if he or she remains employed through the completion of the merger and the remaining 50% if he or she remains employed through the first anniversary of completion of the merger. In the event that a participant’s employment is terminated without “cause” (as defined in the plan) or as a result of the participant’s death or disability or because the participant refuses to accept a new position with a reduced base salary or reduced target bonus opportunity, the participant will receive the bonus payments he or she would have received had he or she remained employed

118

until the first anniversary of the merger. In the event that the merger is not completed, no payments will be made pursuant to the employee retention bonus plan. FPL Group has reserved the right to amend the employee retention bonus plan in any way, other than to increase the aggregate amount that may be paid to all plan participants. In order for any executive officer to participate in the employee retention bonus plan, the compensation committee of the FPL Group board of directors must approve such participation. FPL Group and Constellation have agreed to work together in good faith to establish retention programs or policies that are in the best interest of the combined company.

The following table shows the maximum potential bonus, based on compensation levels in effect on the date of this joint proxy statement/prospectus, that each executive officer of FPL Group who is a participant in the employee retention bonus plan is eligible to receive under the plan.


Executive Officer	Maximum Potential Retention Bonus
Mr. Paul I. Cutler	$	457,852
Mr. K. Michael Davis	$	561,966

Pre-Closing Actions

FPL Group has reserved the right, prior to completion of the merger, to take the following actions:

•

amend the employment agreement between FPL Group and Mr. Hay to reflect the provisions of the merger agreement, as described in the section “Post Merger Governance and Management—Appointment and Removal of Officers” beginning on page 149;

•

increase compensation and benefits of directors, executive officers and employees in the ordinary course of business consistent with past practice; and

•

grant additional equity-based awards with respect to up to 5,500,000 shares of FPL Group common stock (or equivalents thereof), provided that such grants are made in the ordinary course of business consistent with past practice.

Indemnification and Insurance

Constellation has agreed pursuant to the merger agreement to continue to provide certain rights of indemnification to directors and officers of FPL Group following the completion of the merger and to continue to provide directors and officers of FPL Group directors’ and officers’ liability insurance following the completion of the merger. See “The Merger Agreement—Covenants—Indemnification and Insurance” beginning on page 139.

Restrictions on Sales of Shares by Affiliates of FPL Group

All shares of Constellation common stock received by FPL Group shareholders pursuant to the merger will be freely transferable, except that shares of Constellation common stock received by persons who are deemed to be “affiliates” of FPL Group under the Securities Act of 1933 at the time of the FPL Group annual meeting may be resold by them only in transactions permitted by Rule 145 under the Securities Act of 1933 or as otherwise permitted under the Securities Act of 1933. Persons who may be deemed to be affiliates of FPL Group for such purposes generally include individuals or entities that control, are controlled by or are under common control with, FPL Group, as the case may be, and include directors and certain executive officers of FPL Group. See “The Proposed Merger—Federal Securities Law Consequences; Stock Transfer Restriction Agreements” beginning on page 112 for more information on the transfer restrictions to which affiliates of FPL Group as of the annual meeting of the FPL Group shareholders would be subject with respect to the shares of Constellation common stock to be issued pursuant to the merger agreement.

Beneficial Ownership of FPL Group Common Stock by FPL Group’s Directors and Executive Officers

For information regarding beneficial ownership of FPL Group common stock by each current FPL Group director and executive officer and all directors and executive officers as a group, see “Other Matters to be

119

Considered at the Annual Meetings—FPL Group Proposal 2: Election of Directors—Common Stock Ownership of Certain Beneficial Owners and FPL Group Management” beginning on page 192.

Additional Interests of Constellation’s Directors and Executive Officers in the Merger

Under the terms of various contractual agreements and corporate benefit and incentive plans, Constellation’s executive officers and directors will be entitled to receive certain payments and benefits in connection with the completion of the merger. The agreements and plans provide for payments and benefits under the following two circumstances:

•

If an individual’s employment with Constellation is terminated under specified circumstances following the merger; and

•

Upon completion of the merger, with respect to currently outstanding equity and long-term incentive awards.

As described below, in connection with the merger, Constellation established a retention program for its employees. However, no executive officers have been granted awards under this program.

Payments Due Upon a Termination of Employment

Under the terms of change in control severance agreements with eight of Constellation’s executive officers, and under the terms of Constellation’s annual incentive bonus plan, which covers approximately 150 Constellation employees, an executive officer whose employment with Constellation is terminated under specified circumstances following the completion of the merger will be entitled to receive specified payments and benefits. None of these payments or benefits will be received by executive officers who remain employed with Constellation for at least two years following completion of the merger.

Change in Control Severance Agreements

Each of Mayo A. Shattuck III, E. Follin Smith, Thomas F. Brady, Thomas V. Brooks, Michael J. Wallace, Irving B. Yoskowitz, John R. Collins, and Marc L. Ugol is a party to a change in control severance agreement with Constellation. In November 2005, the Compensation Committee of the Constellation board of directors approved amendments to these agreements, which are reflected in amended and restated agreements that were executed in December 2005 and January 2006. We refer to the amended and restated agreements as the “Change in Control Agreements.” The amendments did not alter the fact that completion of the merger will constitute a change in control under the Change in Control Agreements.

In general, payments and benefits under the change in control severance agreements are intended to provide salary and bonus payments and retirement and insurance payments and benefits equal to what an executive whose employment is terminated following the merger would have received if he or she had continued to be employed for an additional two or three years (depending on the terms of the individual’s agreement).

Potential Cash Severance Payments. If the employment of an executive who is party to a Change in Control Agreement is terminated by Constellation without “cause,” or if the executive resigns with “good reason” (as such terms are defined in the executive’s Change in Control Agreement), and if this occurs within two years following completion of the merger, a “qualifying termination” occurs. In such event, the executive (other than Mr. Brooks) would become entitled to receive a lump-sum cash severance payment equal to two times (for Mr. Collins) or three times (for Messrs. Brady, Shattuck, Ugol, Wallace and Yoskowitz and Ms. Smith) the sum of (i) the executive’s then current annual base salary or the executive’s annual base salary at the time of the merger, whichever is higher, plus (ii) the executive’s average annual incentive bonus (calculated as the average of the executive’s two highest annual incentive bonus amounts in the past five years, measured from the date of

120

the merger or the date of termination of employment, whichever is higher). In connection with entering into the employment agreement described in “ —New Employment Agreement with Mr. Shattuck” beginning on page 128, Mr. Shattuck waived the payment of any cash severance he would have been entitled to receive under his Change in Control Agreement. In addition, Mr. Shattuck subsequently executed waivers of certain other payments and benefits contemplated by the employment agreement and his Change in Control Agreement, and the description in this section “Additional Interests of Constellation’s Directors and Executive Officers in the Merger” reflects the effect of those waivers.

If Mr. Brooks’ employment terminates at any time during the two year period following completion of the merger and it is a “qualifying termination,” Mr. Brooks would become entitled to a lump-sum cash severance payment equal to the lesser of $5,000,000 and two times the sum of (i) his then-current annual base salary or his annual base salary at the time of completion of the merger, whichever is higher, plus (ii) his average annual incentive bonus (calculated as the average of the two highest annual incentive bonus amounts in the past five years, measured from the date of the merger or the date of termination of employment, whichever is higher).

Based upon compensation and benefit levels in effect on June 23, 2006 and assuming the merger was completed on December 31, 2006 and a “qualifying termination” occurred immediately thereafter, each executive officer who is a party to a Change in Control Agreement would be entitled to receive the following cash severance payments in connection with the termination of his or her employment.


Executive Officer	Cash severance payments
Mr. T. Brady	$	2,760,000
Mr. T. Brooks	$	5,000,000
Mr. J. Collins	$	1,167,500
Mr. M. Shattuck		—
Ms. F. Smith	$	6,562,500
Mr. M. Ugol	$	2,175,000
Mr. M. Wallace	$	5,737,500
Mr. I. Yoskowitz	$	4,095,300

For a discussion of cash severance payments that would be owed upon a termination of employment to executive officers who are not parties to a Change in Control Agreement, see “—Senior Management Retention Program and Senior Management Severance Plan” beginning on page 130.

Potential Enhanced Supplemental Retirement Benefits. If the employment of an executive who is party to a Change in Control Agreement (other than Messrs. Brooks and Shattuck) is terminated within two years following the merger, and if that termination is a “qualifying termination,” then the executive would become entitled to receive a lump-sum cash payment in respect of enhanced supplemental retirement benefits under Constellation’s Senior Executive Supplemental Plan, its Supplemental Pension Plan or its Benefits Restoration Plan (the “Constellation Supplemental Plans,” which are described in “Other Matters to be Considered at the Annual Meetings—Constellation Proposal 3: Election of Directors—Executive Compensation—Pension Benefits” beginning on page 178), calculated as of the date of termination or the merger, whichever is greater, by (a) waiving any age and service eligibility requirements, (b) using a deemed average annual incentive bonus amount in lieu of any other annual incentive bonus amount, (c) adding three years of executive level service (two years for Mr. Collins) to the executive’s actual service, and (d) for the purposes of computing the present value of the benefit that otherwise would be paid to the executive at age 62, adding three years to the executive’s age (two years for Mr. Collins). In general, the enhancements are intended to provide an executive whose employment is terminated following the merger with the additional value that would have been received if he or she had continued to be employed for an additional two or three years (depending on the terms of the individual’s Change in Control Agreement). For an executive who has satisfied the age and service eligibility requirements of the Constellation Supplemental Plans as of the date of a “qualifying termination” (meaning that the executive

121

would have been entitled to receive his or her supplemental retirement benefit upon any termination of employment, even if the merger had not occurred), this arrangement does not provide for any accelerated vesting of such executive’s supplemental retirement benefits.

Mr. Brooks is not entitled to any enhanced supplemental retirement benefits or any accelerated vesting of such benefits. Mr. Shattuck is not currently vested in any portion of the supplemental retirement benefits under the Constellation Supplemental Plans (although he will be vested in Constellation’s Benefits Restoration Plan as of December 31, 2006). None of those supplemental retirement benefits will vest on an accelerated basis or become payable to him as a result of the completion of the merger and the changes to his position, responsibilities and compensation that are contemplated by the employment agreement, which will take effect upon the completion of the merger. The employment agreement modifies the enhancements to Mr. Shattuck supplemental retirement benefits, as discussed in “—New Employment Agreement with Mr. Shattuck” beginning on page 128. Absent a future event that entitles Mr. Shattuck to accelerated vesting of his supplemental retirement benefits under the Constellation Supplemental Plans, he will not become fully vested in such benefits until 2011.

Based upon compensation and benefit levels in effect on June 23, 2006 and assuming the merger was completed on December 31, 2006 and a qualifying termination occurred immediately thereafter, each executive officer who is a party to a Change in Control Agreement would be entitled to receive the following accelerated and enhanced supplemental retirement benefits in connection with the termination of his or her employment:


Executive Officer	Acceleration of amounts executive would otherwise have received if not terminated prior to standard vesting (A)		Enhancement if terminated (B)		Total potential value if terminated (A + B)
Mr. T. Brady		—	$	1,318,800	$	1,318,800
Mr. T. Brooks		—		—		—
Mr. J. Collins		—	$	235,700	$	235,700
Mr. M. Shattuck		—	$	4,267,300	$	4,267,300	⁽¹⁾
Ms. F. Smith	$	3,301,600	$	3,863,500	$	7,165,100
Mr. M. Ugol	$	267,000	$	314,500	$	581,500
Mr. M. Wallace		—	$	6,399,100	$	6,399,100
Mr. I. Yoskowitz	$	211,400	$	727,100	$	938,500

(1)	Reflects the value of enhancements to Mr. Shattuck’s supplemental retirement benefits specified in his Change in Control Agreement, as modified by his employment agreement, which is described in “—New Employment Agreement with Mr. Shattuck” beginning on page 128.

Other Potential Benefits. In the event of a “qualifying termination,” each executive officer who is a party to a Change in Control Agreement (other than Mr. Brooks) will receive two or three years of continued health and life insurance benefits, depending on the terms of the executive’s agreement. Constellation estimates the cost of these benefits to be between $29,000 and $46,000 for each executive officer. For a discussion of other benefits payable upon termination of employment to an executive officer who is not a party to a Change in Control Agreement, see “—Senior Management Retention Program and Senior Management Severance Plan” beginning on page 130.

If an executive who is party to a Change in Control Agreement would be subject to the excise tax as a result of Section 280G of the Internal Revenue Code, and is required to make a payment due to the application of this section, the executive will receive a gross-up payment such that he or she is placed in the same after-tax position as if no excise tax had been imposed. Constellation estimates, based on assumptions that it believes are reasonable, that the maximum aggregate amount of gross-up payments that could be owed to the executives who are parties to the Change in Control Agreements would be approximately $15 million. In addition, Constellation

122

has the right to delay payments to comply with Section 409A of the Internal Revenue Code and the obligation to notify the executive if a payment would be subject to Section 409A, as well as to negotiate reasonably and in good faith to amend the terms of the arrangements between the executive officer and Constellation to comply with Section 409A of the Internal Revenue Code. Constellation has also agreed not to take actions (without the executive’s written consent) that would expose any benefits or payments to the executive to additional taxes under Section 409A of the Internal Revenue Code and to hold the executive harmless for any action Constellation may take in violation of these obligations.

The Change in Control Agreements also entitle Constellation’s executive officers to receive certain “replacement” options, having specified terms and conditions as discussed in “—Treatment of Outstanding Awards under Constellation’s Compensation Plans—Treatment of Constellation Long-Term Incentive Plan Awards” beginning on page 124.

Treatment of Annual Incentive Bonus in Year of Employment Termination

Pursuant to the Constellation Executive Annual Incentive Plan, Constellation officers and key employees are eligible for annual incentive awards based on the achievement of specified performance goals. Approximately 150 employees participate in the Plan. The Plan provides that if a Plan participant’s service is terminated within two years following a change in control the participant will be entitled to receive his or her target award for the year of termination, calculated assuming the participant has achieved the maximum performance possible. The award will be pro-rated for the portion of the year worked, although the Compensation Committee of the Constellation board of directors has the discretion to award the entire annual amount. Payment of the award will be made in a lump sum in cash within 60 days of the participant’s separation from service. The completion of the merger will constitute a change in control under the Executive Annual Incentive Plan.

The following table sets forth, individually for each executive officer of Constellation who is a party to a Change in Control Agreement, and for the other five executive officers as a group, the entire full-year amount that each Constellation executive officer would be entitled to receive, assuming completion of the merger and termination of such executive officer’s employment with Constellation on December 31, 2006 (with no pro-ration, because the annual incentive period ends on December 31, 2006).


Executive Officer	Award for Year of Termination (assuming termination on December 31, 2006)
Mr. T. Brady	$	510,000
Mr. T. Brooks	$	—	⁽¹⁾
Mr. J. Collins	$	352,500
Mr. M. Shattuck	$	—	⁽²⁾
Ms. F. Smith	$	1,725,500
Mr. M. Ugol	$	450,000
Mr. M. Wallace	$	1,575,000
Mr. I. Yoskowitz	$	1,068,800
All other executive officers as a group	$	1,737,000	⁽³⁾

(1)	Mr. Brooks is not eligible for such a payment because he does not have a specified target award.

(2)

Mr. Shattuck will not be entitled to receive any incentive award under the Annual Incentive Plan as a result of termination of employment following completion of the merger. He will be entitled to receive an incentive award under the Plan solely based upon the achievement of applicable performance metrics.

(3)	Two of the other five executive officers are not eligible for such a payment because they do not have specified target awards.

Treatment of Outstanding Awards Under Constellation’s Compensation Plans

Treatment of Constellation Long-Term Incentive Plan Awards.

Stock Options. Under the Constellation 2002 Senior Management Long-Term Incentive Plan, the Executive Long-Term Incentive Plan, the Management Long-Term Incentive Plan and the 1995 Long-Term Incentive Plan (such plans, collectively, the “Constellation Stock Plans”), the completion of the merger will constitute a change in control. As a result, the vesting of all outstanding Constellation stock options to purchase Constellation common stock that were granted under these plans prior to the end of 2005 will be accelerated and will be immediately exercisable in full.

In addition, on the closing of the merger, options granted under the 2002 Senior Management Long-Term Incentive Plan or the Executive Long-Term Incentive Plan that are vested will be canceled, and Constellation will pay the holders of such vested options cash equal to any gain on the options. All outstanding options granted under the Management Long-Term Incentive Plan or the 1995 Long-Term Incentive Plan prior to the end of 2005 will remain outstanding, will be fully vested and exercisable and will be adjusted to reflect the stock split.

Under the terms of their Change in Control Agreements, executive officers will receive a grant of “replacement” options to purchase a number of shares of Constellation common stock equal to the number of shares (as adjusted to reflect the stock split) subject to options that the executive holds and that are cancelled upon completion of the merger. The replacement options will be subject to the same vesting terms and expiration dates as options that were canceled, except that (a) the exercise price of the replacement options will be the higher of the exercise price of the canceled options (as adjusted to reflect the stock split) or the fair market value of the Constellation common stock at the time the replacement options are granted and (b) the replacement options will have the same vesting terms that the canceled options had prior to any vesting acceleration as a result of the merger. The replacement options will automatically vest if, within two years following the completion of merger, Constellation terminates the executive’s employment without “cause” or the executive resigns for “good reason” (in each case, as defined in the Change in Control Agreement, except that in the case of Mr. Shattuck “good reason” will be as defined in his employment agreement). Executive officers who are not party to a Change in Control Agreement will receive similar replacement options, as the Compensation Committee of the Constellation board of directors has determined to grant such replacement options to all Constellation employees who hold options under the Constellation Stock Plans that will be cancelled upon completion of the merger. Such replacement options will have the same terms and conditions as are specified in the Change in Control Agreements, except that they will automatically vest within two years following the merger only if Constellation terminates the employee without “cause” (as such term is defined by the Compensation Committee).

124

The following table sets forth, individually for each executive officer of Constellation who is a party to a Change in Control Agreement, and for the other five executive officers as a group, the following, assuming completion of the merger on December 31, 2006: (i) the amount in cash, assuming a per share price of Constellation common stock of $52.00, that would be received in respect of stock options that, as of December 31, 2006, would be fully vested and that will be cancelled on completion of the merger, (ii) the amount in cash, assuming a per share price of $52.00, that would be received in respect of stock options that, as of December 31, 2006, would be unvested, but will become fully vested and will be cancelled upon completion of the merger and (iii) the number of shares that will be subject to replacement options that will be granted upon completion of the merger (without adjustment to reflect the stock split). The actual amount of cash received may be higher or lower depending on the value of Constellation common stock on the date on which the merger is actually completed.


Executive Officer	Cash paid upon cancellation of outstanding vested stock options		Cash paid upon cancellation of outstanding unvested stock options		Number of shares of Constellation common stock subject to replacement options
Mr. T. Brady	$	3,066,000	$	260,000	220,880
Mr. T. Brooks⁽¹⁾	$	1,204,000	$	496,000	561,466
Mr. J. Collins	$	1,767,000	$	107,000	121,150
Mr. M. Shattuck ^{(1), (2)}	$	1,258,000	$	1,374,000	1,570,344
Ms. F. Smith ⁽¹⁾	$	809,000	$	353,000	437,290
Mr. M. Ugol	$	972,000	$	107,000	79,150
Mr. M. Wallace ⁽¹⁾	$	740,000	$	302,000	422,686
Mr. I. Yoskowitz ⁽³⁾	$	—	$	—	163,830
All other executive officers as a group ⁽⁴⁾	$	2,548,000	$	132,000	213,701

(1)

Dollar amounts and numbers of replacement options include payments for, and replacements of options to purchase 1,051,361, 361,897, 295,710, and 271,684 shares of Constellation common stock that were granted to Messrs. Shattuck, Brooks and Wallace and Ms. Smith, respectively, on December 21, 2005 in connection with the exercise, at the request of Constellation, of certain of their outstanding options. See “Other Matters to be Considered at the Annual Meetings — Constellation Proposal 3: Election of Directors—Executive Compensation” beginning on page 172 for information regarding option exercises and grants in 2005.

(2)

See “—New Employment Agreement with Mr. Shattuck” beginning on page 128 for a description of additional accelerated vesting and survival arrangements that would apply in certain circumstances to options granted to Mr. Shattuck. Mr. Shattuck has informed Constellation that he intends to direct Constellation to remit all of the after-tax cash proceeds that he would otherwise receive upon the closing of the merger to a charitable foundation or other charitable organization.

(3)

Under the terms of an employment letter between Mr. Yoskowitz and Constellation, options to purchase Constellation common stock that are unvested will continue to vest following a termination of his employment for any reason other than a termination by Constellation for “cause,” or by Mr. Yoskowitz without “good reason,” and all such options will remain outstanding for the remainder of their term.

(4)

This group of executive officers also holds aggregate options to purchase 12,937 shares of Constellation common stock that are subject to accelerated vesting on the completion of the merger but will not be cancelled and will remain outstanding in accordance with the terms of the applicable Constellation Stock Plan. The average weighted exercise price of these options is $39.63.

Restricted Stock and Restricted Stock Units. Each share of Constellation restricted stock and each Constellation restricted stock unit granted on or prior to the date of the merger agreement under the 2002 Senior Management Long-Term Incentive Plan or the Executive Long-Term Incentive Plan will be adjusted at the closing of the merger to reflect the stock split and will immediately vest, with the holder becoming entitled to receive, in full satisfaction of the rights of such holder with respect to each such share of restricted stock or restricted stock unit, an amount in cash equal to the fair market value of one share of Constellation common stock within 30 days of the completion of the merger.

125

Restricted stock and restricted stock units granted under the Management Long-Term Incentive Plan or the 1995 Long-Term Incentive Plan on or prior to the date of the merger agreement will be adjusted at the closing of the merger to reflect the stock split and will vest on the closing of the merger on a pro rata basis (if not already vested), based on the number of months from the start of the applicable restriction period to the date of the closing of the merger (as compared to the total number of months in the restriction period for the shares of restricted stock or restricted stock units). Each holder of a share of vested restricted stock or a vested restricted stock unit will be entitled to receive, in full satisfaction of the rights of such holder with respect to each such share of restricted stock or restricted stock unit, an amount in cash equal to the fair market value of one share of Constellation common stock within 30 days of the completion of the merger. Each share of restricted stock and each restricted stock unit granted under the two plans that does not become vested as a result of the merger will remain outstanding and continue to vest in accordance with its terms.

Performance Units. Constellation performance units granted under the Constellation Stock Plans on or prior to the date of the merger agreement will vest on the closing of the merger on a pro rata basis, based on the number of months from the start of the applicable performance period to the date of the closing of the merger (as compared to the total number of months in the performance period for the performance units). Holders of vested performance units will be entitled to receive, in full satisfaction of their rights with respect to vested units, an amount in cash equal to $2 per unit within 30 days of the completion of the merger. Any performance units that do not vest as of the date of the completion of the merger will terminate.

Outstanding performance units were granted for two performance periods:

•

2004 LTIP: performance period of 2004 through 2006

•

2005 LTIP: performance period of 2005 through 2007

If the merger is completed on December 31, 2006, the performance period for the 2004 LTIP performance units will have been completed. Consequently, the only additional payment for the 2004 LTIP performance units would result from the plan’s requirement that performance units be paid assuming the achievement of maximum performance targets, resulting in a payment of $2 per unit. If the merger is completed after the payout date for the 2004 LTIP (currently scheduled for early 2007), there will be no additional payment related to the merger in respect of the 2004 LTIP performance units, as these units will have been paid out in accordance with their terms prior to merger completion. As noted above, payout of 2005 LTIP performance units and, if the merger closes before December 31, 2006, the 2004 LTIP performance units, will be pro-rated to reflect the portion of the applicable performance period completed prior to the merger.

126

The following table sets forth, individually for each executive officer of Constellation who is a party to a Change in Control Agreement, and for the other five executive officers as a group, the amount in cash, assuming completion of the merger on December 31, 2006 and a per share price of Constellation common stock of $52.00, that would be received in respect of the following: (i) restricted stock units that are currently fully vested but that remain subject to a transfer restriction provision and (ii) outstanding shares of restricted stock and performance units that would not have been vested on the date of completion of the merger, but will become vested on an accelerated basis on such date. The actual amounts of cash received may be higher or lower depending on the date on which the merger is actually completed (for performance units) and the value of Constellation common stock on the date of completion of the merger (for restricted stock and restricted stock units).


Executive Officer	2004 LTIP— Cash for 2004-2006 Performance Units		2005 LTIP— Cash for 2005-2007 Performance Units		Cash Received in Respect of Restricted Stock and Restricted Stock Units
Mr. T. Brady	$	800,000	$	466,000	$	347,000
Mr. T. Brooks	$	1,500,000	$	1,000,000	$	2,360,000
Mr. J. Collins	$	312,000	$	266,000	$	139,000
Mr. M. Shattuck ⁽¹⁾	$	4,000,000	$	3,400,000	$	2,780,000	⁽²⁾
Ms. F. Smith	$	1,000,000	$	1,000,000	$	582,000
Mr. M. Ugol	$	312,000	$	266,000	$	139,000
Mr. M. Wallace	$	900,000	$	666,000	$	1,770,000
Mr. I. Yoskowitz	$	—	$	1,000,000	$	330,000
All other executive officers as a group	$	822,000	$	856,000	$	5,236,000

(1)	Mr. Shattuck has informed Constellation that he intends to direct Constellation to remit all of the after-tax cash proceeds that he would otherwise receive upon the closing of the merger to a charitable foundation or other charitable organization.

(2)

Excludes shares of restricted stock that will vest by their terms in January 2007, which will not vest on an accelerated basis or be cashed out upon completion of the merger. Such shares of restricted stock will continue to vest in accordance with their original terms and remain outstanding after completion of the merger.

Two members of the Constellation board of directors (Mr. Crooke and Ms. Martin) hold shares of Constellation restricted stock that were not vested as of the date of this joint proxy statement/prospectus and that will immediately vest upon completion of the merger and will be settled in cash. Assuming a per share price of Constellation common stock of $52.00, the amount in cash that each such director would be expected to receive is $45,760. The actual amounts of cash received may be higher or lower depending on the value of Constellation common stock on the date of completion of the merger.

Constellation 2006 Long-Term Incentive Award and Retention Program

Each year, as part of their normal compensation package, approximately 150 Constellation employees, including all of its executive officers, typically receive an award of long-term incentive compensation that consists of a combination of stock options and performance units. These awards are intended to provide an incentive for long-term performance and, through the potential increase in the value of Constellation common stock, compensation opportunities for employees.

For 2006, the Compensation Committee of Constellation’s board of directors concluded that, in light of the pending merger, grants of stock options and/or performance units were not appropriate and that a program focused on retention of employees was required. Therefore, no such long-term incentive awards were made for 2006. Instead, the Committee approved a program that provides for target awards payable in cash. The awards were designed to provide recipients with an approximation of the value they could have expected to earn if they

127

had received ordinary course long-term incentive awards, consistent with Constellation’s past practices. Grants under the program provide for cash payouts of 25% of the total award amount to be made upon the earlier of completion of the merger or March 2007. The remainder of such award would be payable one year thereafter (or earlier upon an individual’s employment being terminated without cause or, in the case of executive officers who are party to Change in Control Agreements, upon resignation for “good reason” (as such term is defined in the Change in Control Agreements)). If the merger is not completed by March 2007, payments under this program will occur on the same dates, however such payments will be subject to the achievement of specified performance criteria.

The following tables sets forth, individually for each executive officer of Constellation who is a party to a Change in Control Agreement, and for the other five executive officers as a group, the maximum potential amount that could be paid to each executive officer of Constellation under this incentive award and retention program, assuming completion of the merger on December 31, 2006:


Executive Officer	25% Initial Payment			75% Payment on First Anniversary of Initial Payment
Mr. T. Brady	$	234,500		$	703,500
Mr. T. Brooks	$	750,000		$	2,250,000
Mr. J. Collins	$	100,000		$	300,000
Mr. M. Shattuck	$	1,950,000	⁽¹⁾	$	5,850,000
Ms. F. Smith	$	625,000		$	1,875,000
Mr. M. Ugol	$	131,300		$	393,800
Mr. M. Wallace	$	335,000		$	1,005,000
Mr. I. Yoskowitz	$	335,000		$	1,005,000
All other executive officers as a group	$	1,836,800		$	5,510,300

(1)	Mr. Shattuck has informed Constellation that he intends to direct Constellation to remit all of the after-tax cash proceeds that he would otherwise receive upon the closing of the merger to a charitable foundation or other charitable organization.

New Employment Agreement with Mr. Shattuck

In connection with the execution of the merger agreement, Mr. Shattuck agreed to requests that he enter into an employment agreement. In the employment agreement, Mr. Shattuck waived his right to receive the lump-sum cash severance payment provided for in his Change in Control Agreement. Because he will not continue as Chief Executive Officer of Constellation following completion of the merger, he would have had the right under his Change in Control Agreement to resign for “good reason” following completion of the merger and collect all of the payments and benefits provided for in that agreement, including the lump-sum cash severance payment. Mr. Shattuck has not previously had an employment agreement with Constellation. The employment agreement was requested to ensure that Mr. Shattuck would remain with the combined company following completion of the merger, so that it would continue to have the benefit of his expertise.

The employment agreement has a three-year term and will be void if the merger is not completed. Mr. Shattuck will remain as the Chairman of the Board of Directors of Constellation on completion of the merger. He also will have management responsibilities for Constellation’s competitive energy businesses and assist Constellation’s Chief Executive Officer in developing corporate strategy until the earlier of (a) the first anniversary of completion of the merger and (b) the date on which these management responsibilities are transitioned to new management. Thereafter, Mr. Shattuck will assume other senior management responsibilities as will be agreed by Constellation and Mr. Shattuck. In his role as an executive, Mr. Shattuck will report to Constellation’s Chief Executive Officer. Also, Mr. Shattuck will be nominated to the Constellation board of directors during the three-year term of his employment agreement.

128

Under the employment agreement, Mr. Shattuck’s base salary for 2006 will not be increased after completion of the merger. Members of the Constellation board of directors who were Constellation directors immediately prior to the completion of the merger will determine his bonus for 2006. Mr. Shattuck’s aggregate guaranteed base salary and bonus will be $5,000,000 in 2007 and $2,500,000 in each of 2008 and 2009, provided that his aggregate base salary and bonus in any year will be no less than that of Constellation’s Chief Executive Officer. In addition, Mr. Shattuck’s opportunities under Constellation’s long-term incentive plans and his benefits and perquisites will be at least as favorable as those provided to Constellation’s Chief Executive Officer. So long as he is a director of Constellation, Mr. Shattuck will be entitled to continue security and car services, use of office space in Baltimore, Maryland and the services of a personal assistant or secretary. Mr. Shattuck also has agreed not to knowingly hire, employ or solicit officers of Constellation or key employees of the Constellation Commodities Group for one year after he ceases to be employed by Constellation.

The employment agreement also provides that on completion of the merger, Mr. Shattuck will receive a grant of Constellation restricted stock units (including dividend equivalents) that are subject to complete forfeiture (as described below) and with a fair market value calculated pursuant to the terms of the employment agreement, which, assuming the merger is completed on December 31, 2006, will be approximately $13,500,000. The restricted stock units will vest on the first anniversary of completion of the merger as long as Mr. Shattuck is employed by Constellation at that time. They will vest earlier upon his death or disability or if his employment is terminated by Constellation without “cause” (as defined in his Change in Control Agreement) or by Mr. Shattuck for “good reason” (as defined in the employment agreement) prior to the first anniversary of the completion of the merger, neither of which is expected. If Mr. Shattuck’s employment is terminated by Constellation for “cause” or if he resigns without “good reason,” in either case prior to the first anniversary of the completion of the merger, he will forfeit all of the restricted stock units.

If Mr. Shattuck’s employment is terminated by Constellation without “cause” (as defined in his Change in Control Agreement) or if he resigns for “good reason” (as defined in his employment agreement) at any time during the three-year term of the employment agreement (neither of which is expected), he will be entitled to receive a lump-sum cash termination payment. This termination payment will be equal to the unpaid portion of the aggregate guaranteed salary and bonus for the remainder of the three-year term (as specified in his employment agreement). No such payment will be owed to Mr. Shattuck if his employment terminates any time after the three-year term.

If Mr. Shattuck’s employment is terminated (a) as a result of his death or disability, (b) by Constellation without “cause” or by Mr. Shattuck with “good reason” or (c) after the first anniversary of completion of the merger, for any reason other than by Constellation for “cause,” any Constellation stock options that were granted on or after the date of completion of the merger will vest automatically. In addition, upon a termination of Mr. Shattuck’s employment (other than a termination by Constellation for “cause”), all Constellation stock options that are then vested (or then become vested) will remain outstanding for the remainder of their term. All outstanding equity awards (including options) will vest upon a subsequent change in control of Constellation to the same extent as equity awards held by Constellation’s Chief Executive Officer vest in such circumstance.

If Mr. Shattuck’s employment terminates for any reason following completion of the merger, the provisions in the Change in Control Agreement regarding gross-up payments for excise taxes applicable to payments subject to Section 280G of the Internal Revenue Code and compliance with Section 409A of the Internal Revenue Code, as described in “—Change in Control Severance Agreements” beginning on page 120, will remain applicable.

Under the terms of Mr. Shattuck’s employment agreement and his Change in Control Agreement, any future supplemental retirement benefits that Mr. Shattuck becomes entitled to receive pursuant to the terms of the Constellation Supplemental Plans will be calculated based on (a) the level of his compensation at the date of the merger, (b) his age at termination of employment plus three years, and (c) using actuarial assumptions in effect at the time of termination of Mr. Shattuck’s employment or immediately prior to the merger, whichever are more favorable to Mr. Shattuck.

129

Senior Management Retention Program and Senior Management Severance Plan

Executives who are party to a Change in Control Agreement are not eligible to participate in either the Senior Management Retention Program or the Senior Management Severance Plan.

Senior Management Retention Program. To promote the retention of senior managers, Constellation has established the Senior Management Retention Program. Prior to completion of the merger, Constellation may provide for retention awards to employees, including executive officers, not in excess of $75 million in the aggregate. As of the date of this joint proxy statement/prospectus, no such retention awards have been granted to any executive officers.

Senior Management Severance Plan. Under the terms of the Senior Management Severance Plan, eligible employees whose service with Constellation is terminated without “cause” will be eligible to receive a minimum severance payment based on number of years of service, with a minimum payment of six months of base salary and average bonus, plus medical and dental continuation during the severance period and executive outplacement and educational assistance. Under the plan, an individual will be deemed terminated by Constellation if he or she is required to move more than 50 miles from his or her current office location. If the employment of each of the five executive officers of Constellation who are not party to a Change in Control Agreement were to be terminated (or deemed terminated) the aggregate amount of cash severance that would be payable to these executives under the Senior Management Severance Plan would be approximately $5,646,500.

Deferred Compensation Plan for Non-Employee Directors

Pursuant to the Constellation Deferred Compensation Plan for Non-Employee Directors, notwithstanding a director’s deferral elections or any other provision of the plan relating to distribution of deferred amounts, if a director’s board membership terminates for any reason within one year following a change in control, the director will be entitled to a lump-sum distribution of all amounts deferred under the plan within 30 days of termination of board membership. The completion of the merger will be a change in control under this plan. No determination has been made regarding which current board members will continue as board members of the combined company following the consummation of the merger. The current balance deferred under this plan as of May 30, 2006 is $4,735,000.

Pre-Closing Actions

Constellation has reserved the right, prior to completion of the merger, to take the following actions:

•

grant additional equity-based awards with respect to up to 5,100,000 shares of Constellation common stock (or equivalents thereof), prior to adjusting for the stock split, provided that such grants are made in the ordinary course of business consistent with past practice. Such options will not vest or be subject to cash-out or cancellation upon the completion of the merger;

•

increase compensation and benefits of directors, executive officers and employees in the ordinary course of business consistent with past practice; and

•

provide any employee who becomes subject to an excise tax as a result of Section 280G of the Internal Revenue Code with a gross-up payment such that he or she is placed in the same after tax position as if no excise tax had been imposed.

Indemnification and Insurance

Constellation has agreed pursuant to the merger agreement to continue to provide certain rights of indemnification to directors and officers of Constellation following the completion of the merger and to continue to provide directors and officers of Constellation directors’ and officers’ liability insurance following the completion of the merger. See “The Merger Agreement—Covenants—Indemnification and Insurance” beginning on page 139.

THE MERGER AGREEMENT

The following is a summary of the material terms of the merger agreement. This summary does not purport to describe all the terms of the merger agreement and is qualified by reference to the complete merger agreement which is attached as Annex A to this joint proxy statement/prospectus and incorporated by reference. All stockholders of Constellation and shareholders of FPL Group are urged to read the merger agreement carefully and in its entirety.

The merger agreement has been included to provide you with information regarding its terms. The merger agreement contains representations and warranties Constellation and FPL Group made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between Constellation and FPL Group and may be subject to important qualifications and limitations agreed by Constellation and FPL Group in connection with negotiating its terms. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to stockholders or may have been used for the purpose of allocating risk between Constellation and FPL Group rather than establishing matters as facts.

General

The merger agreement provides for the merger of a newly-formed, wholly owned subsidiary of Constellation with and into FPL Group, with FPL Group continuing as the surviving corporation. As a result of the merger, FPL Group will become a wholly owned subsidiary of Constellation.

Closing Matters

Closing. Unless the parties agree otherwise, the closing of the merger will take place on the third business day after all closing conditions have been satisfied or waived (other than any condition that by its nature cannot be satisfied until the closing), unless the merger agreement has been terminated. See “—Conditions” below for a more complete description of the conditions that must be satisfied or waived prior to closing.

Completion of the Merger. As soon as practicable after the satisfaction or waiver of the conditions to the merger, Constellation and FPL Group will file articles of merger with the Department of State of the State of Florida in accordance with the relevant provisions of the Florida Business Corporation Act and make all other required filings or recordings. The merger will become effective when the articles of merger is filed or at such later time as Constellation and FPL Group agree and specify in the articles of merger.

We are working to complete the merger by the end of 2006 or the first quarter of 2007. However, because completion of the merger is subject to the receipt of regulatory approvals and the satisfaction or waiver of other conditions, we cannot predict the actual timing of the completion of the merger.

Charter and By-laws. Constellation will amend and restate its charter and by-laws, with each amendment and restatement to be effective as of the effective time of the merger. See “—Post-Merger Governance and Management” beginning on page 145 for a description of the material terms and provisions of the amended and restated charter of Constellation, which is the subject of the charter amendment proposal, and the material terms and provisions of the amended and restated by-laws of Constellation.

Consideration to be Received Pursuant to the Merger; Stock Split

The merger agreement provides that, at the completion of the merger, each share of FPL Group common stock issued and outstanding immediately prior to the completion of the merger, but excluding shares of FPL Group common stock owned by Constellation or FPL Group, will be converted into one share of Constellation

132

common stock and all outstanding options to purchase shares of FPL Group common stock granted under the FPL Group stock plans, all shares of FPL Group restricted stock granted under the FPL Group Stock Plans and all outstanding FPL Group other equity-based awards will be treated as described in the section entitled “—Covenants—Employee Matters” beginning on page 138.

Immediately prior to the completion of the merger, the Constellation common stock shall be divided such that each issued and outstanding share of Constellation common stock will be automatically converted into 1.444 fully paid and nonassessable shares of Constellation common stock. Constellation will not issue fractional shares resulting from the stock split. Accordingly, the total number of shares of Constellation common stock that each Constellation stockholder will receive pursuant to the stock split will be rounded down to the nearest whole number, and each Constellation stockholder will receive a cash payment for the remaining fraction of a share of Constellation common stock that he, she or it would otherwise receive, if any, based on the market value of Constellation common stock at the close of business on the last trading day before the closing date of the merger. Constellation does not intend to effect the stock split unless the merger will be completed. As a result of the merger, Constellation stockholders will continue to hold their shares of Constellation common stock, as adjusted by the stock split. Constellation will make appropriate adjustments of existing awards under its stock plans to reflect the stock split. Awards granted under Constellation’s stock plans will be treated as described in the section “—Additional Interests of Constellation’s Directors and Executive Officers in the Merger—Treatment of Outstanding Awards under Constellation’s Compensation Plans—Treatment of Long-Term Incentive Plan Awards” beginning on page 124.

Exchange of Certificates Pursuant to the Merger

Before the closing of the merger, Constellation will appoint a banking or financial institution mutually agreed to by Constellation and FPL Group as the exchange agent to effectuate the exchange of FPL Group stock certificates for certificates representing shares of Constellation common stock. As soon as reasonably practicable after the closing of the merger, the exchange agent will send a letter of transmittal to each former FPL Group shareholder who holds one or more stock certificates. The letter of transmittal will contain instructions explaining the procedure for surrendering FPL Group stock certificates. You should not return stock certificates with the enclosed proxy card.

FPL Group shareholders who surrender their stock certificates, together with a properly completed letter of transmittal, will receive a certificate representing that number of whole shares of Constellation common stock into which their shares of FPL Group common stock were converted pursuant to the merger.

After the merger, each certificate that previously represented shares of FPL Group common stock will only represent the right to receive:

•

certificates representing the shares of Constellation common stock into which those shares of FPL Group common stock have been converted; and

•

dividends or other distributions, if any, of Constellation common stock which FPL Group shareholders are entitled to under the terms of the merger agreement.

Constellation will not pay dividends declared with a record date after the completion of the merger to any holder of any FPL Group stock certificates until the holder surrenders the FPL Group stock certificates. However, once those certificates are surrendered, Constellation will pay to the holder, without interest, any dividends that have been declared and paid after the closing date of the merger on the shares into which those FPL Group shares have been converted, subject to the effect of applicable escheat or similar laws.

After the completion of the merger, FPL Group will not register any transfers of shares of FPL Group common stock.

133

Constellation stockholders will not exchange their stock certificates in connection with the merger. After the stock split is completed, Constellation will send holders of Constellation common stock prior to the effectiveness of the stock split the additional shares of Constellation common stock received as a result of the stock split (and/or cash in lieu of fractional shares resulting from the stock split).

Listing of Constellation Stock

Constellation has agreed to use its reasonable best efforts to cause the shares of Constellation common stock to be issued pursuant to the merger to be approved for listing on the NYSE, subject to official notice of issuance. Constellation’s symbol “CEG” will be used for the shares, assuming the listing application is approved. Approval for listing on the NYSE of the shares of Constellation common stock issuable to the FPL Group shareholders pursuant to the merger, subject only to official notice of issuance, is a condition to the obligations of Constellation and FPL Group to complete the merger. Constellation also has agreed to use its reasonable best efforts to cause the shares of Constellation common stock issuable upon the exercise of FPL Group stock options or otherwise under the FPL Group Stock Plans assumed by Constellation pursuant to the terms of the merger agreement to be approved for listing on the NYSE promptly after completion of the merger.

Covenants

We have each undertaken certain covenants in the merger agreement concerning the conduct of our respective businesses between the date the merger agreement was signed and the completion of the merger. The following summarizes the more significant of these covenants:

No Solicitation. Each of FPL Group and Constellation has agreed that it will not, and will not permit its respective officers, directors, employees, agents or representatives to:

•

solicit, initiate or knowingly encourage, including by way of furnishing information, any inquiries regarding, or the making of any proposal or offer which constitutes a “takeover proposal” of the type described below; or

•

enter into, continue or otherwise participate in any negotiations related to a takeover proposal.

Under the merger agreement, each of FPL Group and Constellation agreed to cease all existing activities, discussions or negotiations as of the date of the merger agreement with any parties with respect to a takeover proposal. Each party agreed to provide written notice to the other on receipt of any request for information by a person who is reasonably likely to make a takeover proposal or who has made a takeover proposal within 24 hours of receiving such request or proposal.

However, each of FPL Group and Constellation is permitted to participate in negotiations with, and furnish information with respect to itself to, a person making a takeover proposal, if:

•

the respective party’s stockholder meeting to vote on the approval of the merger agreement has not occurred;

•

the respective party’s board of directors concludes in good faith that (i) a takeover proposal that was not solicited by it is reasonably likely to result in the delivery of a “superior proposal” of the type described below, and (ii) the failure to participate in negotiation with and furnish information to a person making such a takeover proposal would be reasonably likely to result in a breach of the fiduciary obligations of such party’s board of directors; and

•

within 24 hours of making such conclusion and prior to furnishing any information to a person making a takeover proposal, it has provided written notice to the other party stating that it has received a takeover proposal and has made the conclusion described above and specifying the principal terms and conditions of the takeover proposal.

134

A “takeover proposal” means any bona fide inquiry, proposal or offer from any person relating to:

•

any direct or indirect acquisition or purchase of a business constituting 10% or more of the net revenues, net income or assets of the party and its subsidiaries or 10% or more of the voting power of the outstanding capital stock of the party or any of its material subsidiaries;

•

any tender offer or exchange offer that if completed would result in any person beneficially owning 10% or more of the voting power of the outstanding capital stock of the party or any of its material subsidiaries; or

•

any merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving the party or any material subsidiary as a result of which a third party would acquire 10% or more of the voting securities of the party or any material subsidiary, other than the transactions contemplated by the merger agreement or transactions solely among wholly owned subsidiaries.

A “superior proposal” means any written takeover proposal (as defined above, provided however that 50% should be substituted for all references to 10% in the definition above) which the party’s board of directors determines in good faith (after consultation with a financial advisor of nationally-recognized reputation) to be more favorable to the party’s stockholders than the transactions contemplated by the merger agreement after taking into account, among other things, all financial considerations and aspects of the takeover proposal, all strategic considerations, all legal and regulatory considerations, the identity of the offeror, the conditions and likelihood of completion, the likelihood of the imposition of obligations in connection with obtaining necessary regulatory approval, any financing condition and the likelihood of financing occurring and the payment of any termination fee under the merger agreement.

Board of Directors’ Covenant to Recommend. The FPL Group board of directors has recommended that the FPL Group shareholders approve the merger agreement. Similarly, the Constellation board of directors has recommended that the Constellation stockholders approve the share issuance proposal and the charter amendment proposal.

Neither FPL Group nor Constellation may withdraw or modify its recommendation to its stockholders or approve or enter into any agreement (other than a confidentiality or standstill agreement permitted by the merger agreement) regarding any takeover proposal unless (i) it determines in good faith, after consulting with outside counsel, that failure to take such action would result in a breach of the fiduciary obligations of its board of directors and (ii) it has provided seven days prior written notice of its intent to make a change in its recommendations to the other party, and, if requested by the other party, negotiated in good faith with the other party during such seven-day period to avoid such a recommendation change.

Even if a party’s board of directors withdraws or modifies its recommendation to its stockholders in favor of the proposals related to the merger, the party is still required to submit the proposals relating to the merger agreement at the annual meeting of its stockholders for consideration, unless the merger agreement is otherwise terminated. See “—Termination of Merger Agreement” beginning on page 142 for a discussion of each party’s ability to terminate the merger agreement.

Restrictions on The Parties’ Business Pending Closing. In general, until either the completion of the merger or the termination of the merger agreement, each of Constellation and FPL Group and their respective subsidiaries are required to carry on their businesses in all material respects in the ordinary course and to use commercially reasonable efforts to preserve their business organizations substantially intact and maintain their existing relations with customers, suppliers, employees and other business associates. Each of Constellation and FPL Group has also agreed that (except as contemplated by the merger agreement), without the prior written consent of the other party, it will not and will not permit any of its subsidiaries or other controlled entities to:

•

•

fail to maintain insurance in such amounts and against such risks as are customary for companies engaged in similar businesses; or

Reasonable Best Efforts Covenant. We have each agreed to cooperate with each other and to use our (and cause our respective subsidiaries to use) reasonable best efforts to take or cause to be taken all actions and do or cause to be done all things necessary, proper or advisable under the merger agreement and applicable laws to complete the merger and the other transactions contemplated by the merger agreement as soon as practicable, including obtaining as promptly as practicable all necessary regulatory approvals. Reasonable best efforts shall not require either of Constellation or FPL Group to sell any asset or agree to conduct business in a manner which would have a material adverse effect on either party or on Constellation and its prospective subsidiaries taken as a whole.

We also have agreed to take all action necessary to ensure that no state anti-takeover statutes or similar regulation is or becomes applicable to the merger and, if any state anti-takeover statute becomes applicable, to take all necessary actions to ensure that the merger and other provisions of the merger agreement be completed as soon as reasonably practicable and to minimize the effect of such statute on the merger.

Dividends. Each of Constellation and FPL Group have agreed to coordinate dividend declarations and the related record dates and payment dates so that their stockholders will not receive two dividends, or fail to receive one dividend, for any single calendar quarter. Accordingly, prior to completion of the merger, Constellation and FPL Group may coordinate and amend our record dates and payment dates in order to effect this policy. Each of Constellation and FPL Group have also agreed to other restrictions on the declaration and payment of dividends and other distributions, as noted in the Section “—Restrictions on The Parties’ Business Pending Closing” above.

137

Employee Matters. Prior to the merger occurring, FPL Group will adjust the terms of awards outstanding under the FPL Group Stock Plans or otherwise to provide that:

•

each outstanding FPL Group stock option granted under the FPL Group Stock Plans shall be converted automatically into an option to acquire, on the same terms and conditions, including vesting, a number of shares of Constellation common stock (subject to the prior effectiveness of the stock split) equal to the number of shares that were subject to the FPL Group stock option at an exercise price per share equal to the exercise price of the FPL Group stock option on the same terms and conditions, including vesting, as were applicable to the FPL Group stock option;

•

each share of FPL Group restricted stock shall be converted into one share of Constellation restricted stock (subject to the prior effectiveness of the stock split) on the same terms and conditions, including vesting, as were applicable to such share of FPL Group restricted stock; and

•

each FPL Group other equity-based award shall be converted into an award in respect of a number of shares of Constellation common stock (subject to the prior effectiveness of the stock split) equal to the number of shares that were subject to the FPL Group equity-based award on the same terms and conditions, including vesting, as were applicable to the FPL Group equity-based award.

At the time of the merger, Constellation will be deemed to have assumed all FPL Group Stock Plans and other equity-based awards and obligations. Constellation will take all necessary actions for the assumption, including the reservation, issuance, registration and listing of Constellation common stock in a number at least equal to the number of shares of Constellation common stock that will be subject to awards under the FPL Group Stock Plans.

Following the completion of the merger, Constellation will, and will cause its subsidiaries to, honor all obligations under any employee-related contracts, agreements and collective bargaining agreements of FPL Group and its subsidiaries that existed on December 18, 2005, the date of the merger agreement, and will continue to honor all obligations under any employee-related contracts, agreements and collective bargaining agreements of Constellation and its subsidiaries that existed on the date of the merger agreement.

As discussed under “—Additional Interests of Constellation’s Directors and Executive Officers in the Merger—Treatment of Outstanding Awards under Constellation’s Compensation Plans—Treatment of Long-Term Incentive Plan Awards” beginning on page 124, on the completion of the merger, Constellation employees will be granted replacement options for all options that they hold that were granted on or prior to the date of the merger agreement under Constellation’s 2002 Senior Management Long-Term Incentive Plan or the Executive Long-Term Incentive Plan and are cancelled in exchange for a cash payment on the completion of the merger.

Please also see the discussion under “—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger” beginning on page 113 for a description of the treatment of Constellation options, restricted stock, restricted units and performance units on the completion of the merger.

We agreed that, after the execution of the merger agreement, each of FPL Group and Constellation may implement retention plans for the benefit of employees of the relevant entity. FPL Group has implemented the retention plan discussed under “—Additional Interests of FPL Group’s Directors and Executive Officers in the Merger—FPL Group Retention Bonus Program” beginning on page 118. FPL Group may amend the FPL Group employee retention bonus program in any way, other than increasing the maximum dollar amount subject to the program. Constellation has implemented the retention and severance programs discussed in the sections “—Additional Interests of Constellation’s Directors and Executive Officers in the Merger—Treatment of Outstanding Awards under Constellation’s Compensation Plans—Constellation 2006 Long Term Incentive Award and Retention Program” beginning on page 127 and “—Additional Interests of Constellation’s Directors and Executive Officers in the Merger—Senior Management Retention Program and Senior Management Severance Plan” beginning on page 130. For a description of the amount of each executive officer’s potential retention bonus, see “—Additional Interests of FPL Group’s and Constellation’s Directors and Executive

138

Officers in the Merger” beginning on page 113. Constellation and FPL Group have agreed to work together in good faith to establish retention programs or policies that are in the best interest of the combined company.

Indemnification and Insurance. To the fullest extent permitted by applicable law, Constellation has agreed that:

•

all rights to indemnification of former FPL Group and Constellation directors, officers, employees and fiduciaries under benefit plans for liabilities arising from their acts or omissions occurring prior to closing as provided under their respective certificates of incorporation or by-laws or other agreements in effect on the date of the merger agreement will survive the merger;

•

from and after the closing of the merger, directors, officers, employees and fiduciaries under benefit plans currently indemnified by FPL Group or its subsidiaries or by Constellation and its subsidiaries who obtain or retain such positions with Constellation will be entitled to the indemnity rights and protections offered to directors, officers, employees and fiduciaries under benefit plans of Constellation; and

•

for six years after the completion of the merger, Constellation will maintain FPL Group’s and Constellation’s existing officers’ and directors’ liability insurance covering acts or omissions occurring prior to the closing time of the merger in terms and in amounts no less favorable than those in effect on the date of the merger agreement.

Expenses. We have each agreed to pay our own costs and expenses incurred in connection with the merger and the merger agreement, with the exception that we will each pay 50% of any expenses (other than attorneys’ and accounting fees and expenses) incurred in printing, filing with the SEC and mailing the registration statement of which this joint proxy statement/prospectus forms a part and the filings of the premerger notification and report forms under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (including filing fees). See “—Termination of the Merger Agreement—Termination Fees/Reimbursement of Expenses Payable by Constellation” beginning on page 143 and “—Termination of the Merger Agreement—Termination Fees/Reimbursement of Expenses Payable by FPL Group” beginning on page 144 for a description of the events that may result in one party being required to reimburse the other party for expenses in connection with the merger.

Election to Constellation Board of Directors. At or prior to the completion of the merger, Constellation will expand its board of directors to fifteen members. Immediately after the completion of the merger, nine of the directors will have been directors of FPL Group prior to the completion of the merger and six will have been Constellation directors prior to the completion of the merger. See “Post-Merger Governance and Management—Board of Directors of Constellation” beginning on page 145.

Other Covenants. The merger agreement contains certain other covenants, including covenants relating to public announcements and employee communications, access to information and tax matters.

Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to stockholders or may have been used for the purpose of allocating risk between Constellation and FPL Group rather than establishing matters as facts.

The merger agreement also contains certain representations and warranties made solely by Constellation with respect to its wholly owned merger subsidiary, including corporate authorization, absence of a breach of the certificate of incorporation or the by-laws, lack of prior business activities and capitalization.

As used in the merger agreement, the term “material adverse effect” means with respect to either Constellation or FPL Group, as applicable, any change, effect, event, occurrence or state of facts:

•

that is materially adverse to the business, assets, properties, financial condition or results of operations of such person and its subsidiaries taken as a whole (and of Constellation and its prospective subsidiaries taken as a whole in the case of references to a “material adverse effect on Constellation and

140

general economic conditions in the United States or conditions of the financial or commodities markets in general, to the extent not disproportionately affecting the applicable person as compared to other similarly situated persons;

Termination of Merger Agreement

Right to Terminate. The merger agreement may be terminated at any time prior to the completion of the merger in any of the following ways:

•

by mutual written consent of Constellation and FPL Group;

•

by either Constellation or FPL Group:

•

if the merger has not been completed by December 31, 2006; provided that if all conditions to closing have been fulfilled or are capable of being fulfilled, other than receipt of the required statutory approvals and/or the absence of injunctions on or restraints to the completion of the merger, this date is automatically extended to June 30, 2007; provided, further, that a party may not terminate the merger agreement if the cause of the merger not being completed is that party’s failure to fulfill its obligations under the merger agreement;

•

if either the Constellation stockholders fail to approve the share issuance proposal or charter amendment proposal or the FPL Group shareholders fail to approve the merger agreement;

•

if any final and nonappealable order or injunction by any federal or state court of competent jurisdiction or applicable federal or state law that prevents the completion of the merger is in effect; provided that the party seeking to terminate the merger agreement has used its reasonable best efforts to prevent the entry of and to remove any such order, injunction or law; or

•

if any condition to the obligation of such party to complete the merger becomes incapable of satisfaction prior to the applicable termination date (whether initial or extended); provided that the failure of such condition to be capable of satisfaction is not the result of a material breach of the merger agreement by the party wishing to terminate.

•

by Constellation:

•

if there has been a breach or failure to perform in any material respect of any representation, warranty, covenant or other agreement made by FPL Group in the merger agreement, and the breach or failure to perform:

•

would result in the applicable closing condition to the merger not being satisfied; and

•

is not curable or, if curable, is not cured within 75 days after written notice is given by Constellation to FPL Group; or

•

if the FPL Group board of directors withdraws or modifies, in a manner adverse to Constellation, its recommendation to shareholders regarding the merger or fails to reaffirm its recommendation to shareholders regarding the merger within 15 days of receipt of written request at any time when a takeover proposal for FPL Group has been made (with certain extensions to such time period in the case of amendments of the takeover proposal), provided that Constellation may not terminate if the

142

FPL Group board of directors rescinds any recommendation adverse to Constellation regarding the merger or after FPL Group shareholder approval has been obtained.

•

by FPL Group:

•

if there has been a breach or failure to perform in any material respect of any representation, warranty, covenant or other agreement made by Constellation in the merger agreement, and the breach or failure to perform:

•

would result in the applicable closing condition to the merger not being satisfied; and

•

is not curable or, if curable, is not cured within 75 days after written notice is given by FPL Group to Constellation; or

•

if the Constellation board of directors makes or modifies, in a manner adverse to FPL Group, its recommendation to stockholders regarding the merger or fails to reaffirm its recommendation to stockholders regarding the merger within 15 days of receipt of written request at any time when a takeover proposal for Constellation has been made (with certain extensions to such time period in the case of amendments of the takeover proposal), provided that FPL Group may not terminate if the Constellation board of directors rescinds any recommendation adverse to FPL Group regarding the merger or the Constellation stockholder approval has been obtained.

Termination Fees/Reimbursement of Expenses Payable by Constellation. Constellation will be required to (a) reimburse FPL Group for its fees and expenses in an aggregate amount not to exceed $40 million (subject to certain circumstances where the reimbursement limitation shall not apply) and/or (b) pay a termination fee of $425 million to FPL Group (provided that any termination fee payable will be reduced by the amount of any fees and expenses previously reimbursed and, if previously paid, the $100 million fee described below) in the event that:

•

following Constellation stockholder approval, a takeover proposal for Constellation is made known to the board of directors or any executive officer of Constellation or is publicly known and the merger agreement is terminated by either party because the merger has not been completed by the applicable termination date (whether initial or extended);

•

prior to or during a Constellation stockholder meeting, a takeover proposal for Constellation is disclosed and the merger agreement is terminated by either party because approval of the share issuance proposal or charter amendment proposal is not obtained; or

•

FPL Group terminates the merger agreement because the Constellation board of directors withdrew or modified, in a manner adverse to FPL Group, its recommendation to stockholders regarding the merger, and prior to the adverse stockholder recommendation, a takeover proposal for Constellation was known to the board of directors, executive officers or stockholders of Constellation or publicly known;

provided, however, that no such termination fee will become payable in the first instance unless prior to the 12 month anniversary of the termination of the merger agreement Constellation or any of its subsidiaries consummates or enters into an agreement to consummate the takeover proposal; or in the second or third instance unless prior to the 24 month anniversary of the termination of the merger agreement Constellation or any of its subsidiaries consummates or enters into an agreement to consummate the takeover proposal. Neither the $425 million termination fee described above nor the $100 million fee described below will become payable in the third instance if the Constellation recommendation that was adverse to FPL Group regarding the merger was primarily due to adverse conditions, events or actions of or relating to FPL Group that would result in a failure of a condition to Constellation’s obligations to complete the merger.

In addition, Constellation will pay FPL Group a fee of $100 million, promptly after Constellation stockholder approval is not obtained, in the event that, after a takeover proposal for Constellation is made known to the board of directors or executive officers of Constellation or is publicly known, the Constellation board of directors withdraws or modifies, in a manner adverse to FPL Group, its recommendation to stockholders regarding the merger and a Constellation stockholder meeting is held but Constellation stockholder approval of the share issuance proposal and charter amendment proposal is not obtained.

143

Termination Fees/Reimbursement of Expenses Payable by FPL Group. FPL Group will be required to (a) reimburse Constellation for its fees and expenses in an aggregate amount not to exceed $40 million (subject to certain circumstances where the reimbursement limitation shall not apply) and/or (b) pay a termination fee of $650 million to Constellation (provided that any termination fee payable will be reduced by the amount of any fees and expenses previously reimbursed and, if previously paid, the $100 million fee described below) in the event that:

•

following FPL Group shareholder approval, a takeover proposal for FPL Group is made known to the board of directors or any executive officers of FPL Group or is publicly known and the merger agreement is terminated by either party because the merger has not been completed by the applicable termination date (whether initial or extended);

•

prior to or during a FPL Group shareholder meeting, a takeover proposal for FPL Group is disclosed and the merger agreement is terminated by either party because FPL Group shareholder approval of the merger agreement is not obtained; or

•

Constellation terminates the merger agreement because the FPL Group board of directors withdrew or modified, in a manner adverse to Constellation, its recommendation to shareholders regarding the merger, and prior to the adverse shareholder recommendation, a takeover proposal for FPL Group was known to the board of directors, executive officers or shareholders of FPL Group or publicly known;

provided, however, that no such termination fee will become payable in the first instance unless prior to the 12 month anniversary of the termination of the merger agreement FPL Group or any of its subsidiaries consummates or enters into an agreement to consummate the takeover proposal; or in the second or third instance unless prior to the 24 month anniversary of the termination of the merger agreement FPL Group or any of its subsidiaries consummates or enters into an agreement to consummate the takeover proposal. Neither the $650 million termination fee described above nor the $100 million fee described below will become payable in the third instance if the FPL Group recommendation that was adverse to Constellation regarding the merger was primarily due to adverse conditions, events or actions of or relating to Constellation that would result in a failure of a condition to FPL Group’s obligations to complete the merger.

In addition, FPL Group will pay Constellation a fee of $100 million, promptly after FPL Group shareholder approval is not obtained, in the event that, after a takeover proposal for FPL Group is made known to the board of directors or executive officers of FPL Group or is publicly known, the FPL Group board of directors withdraws or modifies, in a manner adverse to Constellation, its recommendation to shareholders regarding the merger and a FPL Group shareholder meeting is held but FPL Group shareholder approval of the merger agreement is not obtained.

POST-MERGER GOVERNANCE AND MANAGEMENT

This section of the document describes the material governance and management arrangements that will apply to Constellation upon completion of the merger.

Amended and Restated Constellation Charter and By-laws

Constellation is proposing to amend and restate its charter and by-laws to effect various terms of the merger, as described in this joint proxy statement/prospectus, including those elements discussed in this section of the joint proxy statement/prospectus that describes the governance and management arrangements that will apply to Constellation upon completion of the merger. You should read the complete text of the amended and restated charter and by-laws of Constellation, substantially in the form to become effective upon completion of the merger, which are attached as Annex F and Annex G, respectively, to this joint proxy statement/prospectus in conjunction with this summary. The form of amended and restated charter of Constellation and the form of amended and restated by-laws of Constellation that are attached as Annex F and Annex G, respectively, to this joint proxy statement/prospectus are the form of each such document attached as an exhibit to the merger agreement, except that they include additional modifications agreed to between Constellation and FPL Group since the date of the merger agreement. We urge you to read the full text of the proposed amended and restated charter and by-laws of Constellation because they are the legal documents that will govern Constellation upon the completion of the merger. See “Certain Legal Information—Comparison of Stockholders’ Rights” beginning on page 217 for a further discussion of the amended and restated charter and by-laws of Constellation to be effective upon the completion of the merger.

The amendments contemplated by the amended and restated charter of Constellation to be effective upon the completion of the merger, will, among other amendments:

•

add 700 Universe Boulevard, Juno Beach, Florida 33408 as the address of Constellation’s additional principal office;

•

provide that the minimum size of the Constellation board of directors shall be increased from no less than three members to consist of no less than seven members;

•

provide that, as of the closing date of the merger and until the second anniversary of the closing date of the merger, any vacancy on the Constellation board of directors that results from any cause other than an increase in the number of directors will be filled pursuant to Section 10(c)(i) of Article III of the by-laws of Constellation in effect at the closing date of the merger;

•

increase the number of authorized shares of common stock to 1.2 billion;

•

increase the number of authorized shares of preferred stock to 125 million;

•

provide that each share of common stock shall have one vote, and, except as otherwise provided in respect of any class of stock hereafter classified or reclassified, the exclusive voting power for all purposes shall be vested in the holders of the common stock;

•

provide that shares of common stock shall not have cumulative voting rights;

•

to eliminate the requirement that each share of any series of preferred stock have only one vote;

•

provide that dividends may be paid ratably on the common stock at such time and in such amounts as the Constellation board of directors may deem advisable;

•

provide that in the event of any liquidation, dissolution or winding up of Constellation, whether voluntary or involuntary, the holders of the common stock shall be entitled, together with the holders of any other class of stock hereafter classified or reclassified not having a preference on distributions in the liquidation, dissolution or winding up of Constellation, to share ratably in the net assets of Constellation

145

remaining, after payment or provision for payment of the debts and other liabilities of Constellation and the amount to which the holders of any class of stock hereafter classified or reclassified having a preference on distributions in the liquidation, dissolution or winding up of Constellation shall be entitled; and

•

provide that the Constellation board of directors may classify and reclassify any unissued shares of Constellation stock (whether or not such shares have been previously classified or reclassified) by setting or changing in any one or more respects, from time to time before issuance of such shares, the class and series designations of shares of capital stock or setting or changing the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares.

Constellation stockholders may vote on each of the individual amendments contemplated by the amended and restated Constellation charter separately or on all of the amendments collectively. Under the merger agreement, completion of the merger is subject to the satisfaction (or, if legally permitted, waiver) of specified closing conditions. Approval by the Constellation stockholders of the amended and restated Constellation charter is one of those conditions. Constellation and FPL Group may not waive the requirement for Constellation stockholders to approve the charter amendment to increase the number of authorized shares of Constellation common stock.

Constellation does not intend to amend and restate the Constellation charter unless the merger will be completed (even if the Constellation stockholders have approved the charter amendment proposal).

Corporate Offices

The Constellation by-laws to be effective at the completion of the merger will provide that the combined company will maintain dual headquarters in Juno Beach, Florida and Baltimore, Maryland until the fifth anniversary of the completion of the merger or the earlier completion by Constellation of a business combination in which a third party is entitled to designate three or more members of the Constellation board of directors. The affirmative vote of 90% of the members of the entire board of directors (rounded up to the nearest whole number) will be required to change this provision at any time prior to the fifth anniversary of the completion of the merger.

Board of Directors of Constellation

The Constellation by-laws to be effective at the completion of the merger will provide that the board of directors of the combined company will be comprised of 15 directors upon completion of the merger to be comprised of:

•

9 directors chosen by FPL Group prior to the merger; and

•

6 directors chosen by Constellation prior to the merger.

The 9 directors chosen by FPL Group will become “FPL Group Designated Directors” and will consist of eight non-executive directors and the current chief executive officer of FPL Group. “FPL Group Designated Director” means (i) any person serving as a director of FPL Group who becomes a director of Constellation upon completion of the merger and (ii) any person designated by a majority of the remaining FPL Group Designated Directors to fill a vacancy caused by the departure of a director of the type described in clause (i) of this sentence.

The 6 directors chosen by Constellation will become “Constellation Designated Directors” and will consist of five non-executive directors and the current chief executive officer of Constellation. “Constellation Designated Director” means (i) any person who continues as a director of Constellation upon completion of the merger and (ii) any person designated by a majority of the remaining Constellation Designated Directors to fill a vacancy caused by the departure of a director of the type described in clause (i) of this sentence.

146

The Constellation by-laws will provide that, until the second anniversary of the merger, the board of directors will take all necessary action to ensure that (i) any vacancy in a position held by a Constellation Designated Director will be filled by a person designated by a majority of the remaining Constellation Designated Directors and (ii) any vacancy in a position held by a FPL Group Designated Director will be filled by a person designated by a majority of the remaining FPL Group Designated Directors.

The Constellation by-laws will provide that, until the second anniversary of the merger, any vote by the board of directors to alter the provisions set forth above will require the affirmative vote of at least 70% of the members of the entire board of directors (rounded up to the nearest whole number).

Upon completion of the merger, the board of directors of Constellation will be unclassified and each director will be required to stand for election at each annual meeting.

Effective upon completion of the merger, Mayo A. Shattuck III will serve as Chairman of the Board of Directors as a Constellation Designated Director and Lewis Hay, III will serve as a member of the board of directors as a FPL Group Designated Director.

Nomination of Director Candidates; Removal of Directors

Nomination of Constellation Directors

The Constellation by-laws to be effective at the completion of the merger will provide that, until the second anniversary of the merger, with respect to each election of directors by stockholders, the board of directors will nominate for election to each position previously held by a Constellation Designated Director, a person designated by a majority of the remaining Constellation Designated Directors, and, for each position previously held by a FPL Group Designated Director, a person designated by a majority of the remaining FPL Group Designated Directors. The Constellation by-laws will provide that, until the second anniversary of the merger, any vote by the board of directors to alter this provision will require the affirmative vote of at least 70% of the members of the entire board of directors (rounded up to the nearest whole number).

Removal of Constellation Directors

The amended and restated Constellation charter to be effective as of the completion of the merger will provide that any director may be removed at any time but only for cause and only by the affirmative vote of the holders of a majority of the total votes entitled to be cast by the holders of all classes of stock of Constellation entitled to vote at an election of directors, voting together as a single class, subject to the rights of any holders of any class entitled to separately elect one or more directors.

Other Board of Directors Matters

Meetings of the Board of Directors

The Constellation by-laws to be effective at the completion of the merger will provide that, until at least the end of the calendar year in which the fifth anniversary of the merger occurs, at least two board meetings each calendar year shall be held in each of Baltimore, Maryland and Juno Beach, Florida (or in the general vicinity of each city). If the merger occurs after June 30 in any calendar year, this requirement shall not apply for such calendar year, except that if there are two or more board meetings in the remainder of such calendar year, one board meeting will be required to be held in each of Baltimore, Maryland and Juno Beach, Florida (or in the general vicinity of each city). Until the fifth anniversary of the merger, this provision of the Constellation by-laws may only be amended by the affirmative vote of 90% of the members of the entire board of directors (rounded up to the nearest whole number).

147

Committees of the Board of Directors

The Constellation by-laws to be effective at the completion of the merger will provide that the board of directors may appoint from among its members one or more committees as it may, from time to time, deem advisable.

At the effective time of the merger, the board of directors shall appoint an audit committee, a compensation committee, a finance and investment committee, a governance and nominating committee and a nuclear power committee. Until the second anniversary of the merger, a FPL Group Designated Director will chair each of the audit, finance and investment and governance and nominating committees and a Constellation Designated Director will chair each of the compensation and nuclear power committees of the board of directors. During this time, the representation of FPL Group Designated Directors and Constellation Designated Directors on each committee of the board of directors will be in proportion to their relative representation on the entire board of directors. Until at least the second anniversary of the merger, there will be no executive committee of the board of directors.

The Constellation by-laws will provide that, until the second anniversary of the merger, any vote by the board of directors to alter the provision set forth above will require the affirmative vote of at least 70% of the members of the entire board of directors (rounded up to the nearest whole number).

The chair of the governance and nominating committee of the board of directors will serve as the board of directors’ presiding director until at least the second anniversary of the merger.

Stockholder Nominations of Directors and Other Stockholder Proposals

The Constellation by-laws to be effective at the completion of the merger will provide that a stockholder may nominate persons to stand for election to the board of directors at an annual meeting of stockholders (or special meeting called to elect directors) and may propose other proper business to be considered by the stockholders at an annual meeting of stockholders. In each case, stockholders must comply with the following procedures, among other things, prior to making nominations or proposing business:

•

The stockholder must give timely notice of the nomination or business to be considered to the secretary of Constellation.

•

In the case of an annual meeting, notice must be given not less than 90 nor more than 120 days prior to the first anniversary of the date on which notice of the preceding year’s annual meeting was given to stockholders or, if the annual meeting will be held more than 30 days before or 60 days after that anniversary date, notice must be given no earlier than the 120th day before the meeting and no later than the close of business on the later of the 90th day before the meeting or the 10th day after the first public announcement of the meeting.

•

In the case of a special meeting to elect directors, notice must be given no earlier than the 120th day before the meeting and no later than the close of business on the later of the 90th day before the meeting or the 10th day after the first public announcement of the meeting.

•

If the number of directors to be elected at the annual meeting is increased in accordance with the Constellation by-laws and there is no public announcement naming all of the nominees for directors or specifying the size of the increased board of directors made by Constellation at least 90 days prior to the first anniversary of the date of the immediately preceding annual meeting, notice of nominations with respect to nominees for any new positions created by such increase may be given no later the 10th day after the first public announcement of all of the nominees for directors or of the specific size of the increased board of directors.

148

•

The notice must set forth:

•

as to each director nominee, all information that is required to be disclosed in a proxy solicitation for election of directors under applicable law, including a written consent from the nominee to serve as a director if elected;

•

as to any business that the stockholder proposes to bring before the annual meeting, a brief description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration), the reasons for conducting the business at the meeting, and in the event that such business includes a proposal to amend the Constellation by-laws, the language of the proposed amendment;

•

as to the stockholder giving the notice, (1) name and address of the stockholder on Constellation’s books, (2) the class and number of shares beneficially owned and (3) any material interest of the stockholder in such nomination or other business; and

•

representations that the person giving the notice is a holder of record of Constellation common stock, will appear in person or by proxy at the meeting and, if applicable, that the stockholder intends to solicit proxies.

Officers of Constellation

Constellation and FPL Group have agreed that certain officers of Constellation and FPL Group will continue as or become officers of Constellation upon completion of the merger. See “—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger—Positions with the Combined Company” beginning on page 113 for a further discussion of arrangements regarding these officers.

Appointment and Removal of Officers

The Constellation by-laws to be effective at the completion of the merger will provide that the officers shall be chosen by the board of directors. The board of directors may authorize the chief executive officer to designate and appoint other officers. Officers shall hold their offices for such terms and shall exercise such powers and perform such duties as shall be set out in the Constellation by-laws or as may be assigned. Officers shall hold office until their successors are elected and qualified or appointed, or until their earlier resignation or removal. Any officer may be removed by a majority of the board of directors or, if appointed by the Chief Executive Officer, by the Chief Executive Officer or by any other officer to whom the Chief Executive Officer delegates such authority. Any vacancy occurring in any office shall be filled by the board of directors or by the Chief Executive Officer if authorized to do so by the board of directors.

With regard to the chief executive officer, the Constellation by-laws will provide that until at least the third anniversary of the merger, Lewis Hay, III will serve in that capacity and report directly to the board of directors. During that time, Mr. Hay will be the only officer reporting directly to the board of directors and all other officers and executives will report, directly or indirectly, to Mr. Hay. Until the third anniversary of the merger, the affirmative vote of 70% of the board of directors (excluding Mr. Hay and Mr. Shattuck) will be required to remove Mr. Hay from the position of chief executive officer or to alter the provisions set forth in this paragraph. See “—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger” beginning on page 113 for a further discussion of the arrangements with Messrs. Hay and Shattuck.

CONSTELLATION ENERGY GROUP, INC.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The Unaudited Pro Forma Condensed Combined Financial Statements have been prepared to reflect the merger of FPL Group and Constellation. Although Constellation will be issuing shares of Constellation common stock to FPL Group shareholders to effect the merger, the merger will be accounted for as a reverse acquisition under the purchase method of accounting. Under the purchase method of accounting, FPL Group will be treated as the accounting acquiror and Constellation will be treated as the “acquired” company for financial reporting purposes because, upon completion of the merger, the FPL Group shareholders prior to the merger will have a majority of the voting interest in the combined company and a majority of the initial board of directors of the combined company will be designated by FPL Group. Under the terms of the merger agreement, immediately prior to the completion of the merger, Constellation will effect a stock split pursuant to which each share of Constellation common stock will be converted into 1.444 shares of Constellation common stock. Upon the completion of the merger, each share of FPL Group common stock outstanding immediately prior to the merger will be exchanged for one share of Constellation common stock, and FPL Group will be a wholly owned subsidiary of Constellation. Completion of the merger is subject to obtaining certain required consents and approvals and at this time we cannot predict the likelihood and the actual timing of receipt of these approvals and closing of the merger.

The Unaudited Pro Forma Condensed Combined Financial Statements combine amounts from the historical consolidated financial statements of FPL Group and Constellation and include pro forma adjustments that reflect the fair values of Constellation’s assets and liabilities as of June 30, 2006. These adjustments give effect to the merger as if it had occurred:

•

on January 1, 2005 in the Unaudited Pro Forma Condensed Combined Statements of Income for the year ended December 31, 2005 and for the six months ended June 30, 2006; and

•

on June 30, 2006 in the Unaudited Pro Forma Condensed Combined Balance Sheet as of that date.

You should read these Unaudited Pro Forma Condensed Combined Financial Statements in conjunction with the:

•

accompanying Notes to the Unaudited Pro Forma Condensed Combined Financial Statements;

•

separate unaudited historical financial statements of FPL Group as of and for the three and six month periods ended June 30, 2006, included in the FPL Group Quarterly Report on Form 10-Q for the three and six month periods ended June 30, 2006, which is incorporated by reference into this joint proxy statement/prospectus;

•

separate historical financial statements of FPL Group as of and for the year ended December 31, 2005 included in the FPL Group 2005 Annual Report on Form 10-K for the year ended December 31, 2005, which is incorporated by reference into this joint proxy statement/prospectus;

•

separate unaudited historical financial statements of Constellation as of and for the three and six month periods ended June 30, 2006, included in the Constellation Quarterly Report on Form 10-Q for the three and six month periods ended June 30, 2006, which is incorporated by reference into this joint proxy statement/prospectus; and

•

separate historical financial statements of Constellation as of and for the year ended December 31, 2005 included in the Constellation 2005 Annual Report on Form 10-K for the year ended December 31, 2005, which is incorporated by reference into this joint proxy statement/prospectus.

The historical financial information of FPL Group and Constellation as of and for the six months ended June 30, 2006 reflected in the Unaudited Pro Forma Condensed Combined Financial Statements is unaudited.

150

The historical financial information of each of FPL Group and Constellation for the year ended December 31, 2005 in the Unaudited Pro Forma Condensed Combined Financial Statements is derived from the audited financial statements of FPL Group and Constellation, respectively, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The Unaudited Pro Forma Condensed Combined Financial Statements are provided for informational purposes only. The pro forma information is not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the merger been completed at the dates indicated. In addition, the Unaudited Pro Forma Condensed Combined Financial Statements do not project the future financial position or operating results of the combined company.

The Unaudited Pro Forma Condensed Combined Financial Statements were prepared using the purchase method of accounting. Accordingly, we have adjusted the historical consolidated financial information to give effect to the impact of the consideration deemed to be issued in connection with the merger. In the Unaudited Pro Forma Condensed Combined Balance Sheet, FPL Group’s deemed expected cost to acquire Constellation has been allocated to the assets deemed to be acquired and liabilities deemed to be assumed based upon management’s preliminary estimate of their respective fair values. The difference between the fair value of the consideration deemed to be issued and the fair value of the assets and liabilities deemed to be acquired or assumed will be recorded as goodwill. Definitive allocations will be performed and finalized based upon certain valuations and other studies that will be performed by management with the assistance of outside valuation specialists as of the closing date of the merger. Accordingly, the pro forma purchase allocation adjustments are preliminary, have been made solely for the purpose of providing unaudited pro forma condensed combined financial information, and are subject to revision based on a final determination of fair value as of the closing of the merger. Additionally, management’s preliminary internal valuation includes estimates and assumptions about numerous factors, including, but not limited to, forward prices for power, fuels and emissions allowances, and the level of interest rates. These factors have exhibited significant volatility in the past, and changes in one or more of these factors prior to closing of the merger could have a significant effect on the final determinations of fair value. As a result, the final determinations of fair value may differ materially from those estimates presented in the Unaudited Pro Forma Condensed Combined Financial Statements.

The Unaudited Pro Forma Condensed Combined Statements of Income also include certain purchase accounting adjustments reflecting items expected to have a continuing impact on the combined results, such as increased revenues, fuel and purchased energy expenses and depreciation and amortization expense on acquired tangible and intangible assets and liabilities. The final purchase price allocation may result in changes in these items or the identification and recording of additional intangible assets and liabilities that are subject to amortization that are not yet reflected in these Unaudited Pro Forma Condensed Combined Financial Statements. The impact of changes in revenues, fuel and purchased energy expenses, and depreciation and amortization, as well as the amortization of any additional intangibles, may materially impact future earnings of the combined company.

The purchase method of accounting applied to the merger is based on currently effective accounting guidance. On June 30, 2005, the Financial Accounting Standards Board issued an exposure draft proposing changes to the rules governing the application of purchase accounting. Based on the proposed timing for issuance of a final standard in the second quarter of 2007, we do not currently anticipate that any significant changes to the rules governing purchase accounting will be effective prior to the anticipated completion of the merger. However, we are unable to predict if changes to the rules governing the application of purchase accounting will actually occur, or when any such changes would become effective, or the impact that applying such changes would have on the Unaudited Pro Forma Condensed Combined Financial Statements.

The Unaudited Pro Forma Condensed Combined Statements of Income do not include the impacts of any revenue, cost or other operating synergies that may result from the merger. In addition, the Unaudited Pro Forma Condensed Combined Financial Statements do not reflect the impact of financing, liquidity, or other working capital activity that may be undertaken in connection with or subsequent to the merger.

151

As discussed in Note (h) to the Unaudited Pro Forma Condensed Combined Statements of Income and Note (q) to the Unaudited Pro Forma Condensed Combined Balance Sheet, the effects of transactions between FPL Group and Constellation included in each company’s historical financial statements have been eliminated. The Unaudited Pro Forma Condensed Combined Statements of Income do not reflect the one-time gain or loss that will be recorded by FPL Group to record the effective settlement of preexisting contracts between FPL Group and Constellation at the acquisition date (see balance sheet Note (p)). If the merger had occurred on June 30, 2006, FPL Group would have recorded an after-tax loss of approximately $16 million on the preexisting contracts not reflected on the balance sheet of FPL Group.

Except as discussed in Note (j) to the Unaudited Pro Forma Condensed Combined Balance Sheet, the Unaudited Pro Forma Condensed Combined Financial Statements do not reflect any nonrecurring charges related to the merger. Nonrecurring charges related to mergers typically consist of restructuring or exit costs that are expected to result from the merger. Such nonrecurring charges related to the merger incurred by Constellation may be recognized in the opening balance sheet if certain criteria are met. Direct, incremental third party transaction costs incurred by FPL Group will be allocated to the assets deemed acquired and liabilities deemed assumed in the merger. All other merger-related costs related to FPL Group and Constellation will be expensed as incurred. At this time, the status of integration plans and merger-related costs, except as discussed in Note (j) to the Unaudited Pro Forma Condensed Combined Balance Sheet, is too uncertain to include the anticipated effects of such plans and costs in the pro forma financial statements.

Except as discussed in Note (d) to the Unaudited Pro Forma Condensed Combined Statements of Income, the Unaudited Pro Forma Condensed Combined Financial Statements do not reflect any adjustments to conform Constellation’s accounting policies to FPL Group’s accounting policies. FPL Group and Constellation will continue to evaluate the need to conform accounting policies and upon completion of the merger, Constellation’s accounting policies and financial statements may be revised to conform Constellation’s policies and classifications to those of FPL Group. The impact of these changes on the consolidated results of operations of the combined company may be material.

Constellation’s regulated operations are comprised of BGE’s electric transmission and electric and gas distribution operations. These portions of BGE’s operations are subject to the rate-setting authority of the MPSC and FERC and are accounted for pursuant to SFAS No. 71, Accounting for the Effects of Certain Types of Regulation. The Unaudited Pro Forma Condensed Combined Financial Statements have been prepared on a basis assuming that the merger will not have any impact on the determination of utility service rates for BGE’s regulated operations. However, any change in the rate-setting practices of the MPSC or FERC could have a material effect on Constellation’s financial statements. The rate-setting and cost recovery provisions currently in place for BGE’s regulated operations provide revenues derived from cost, including a return on investment for assets and liabilities included in rate base, except for certain assets and liabilities discussed below. Thus, the fair values of BGE’s individual tangible and intangible assets and liabilities, including debt securities, subject to these rate-setting provisions approximate their carrying values, and the Unaudited Pro Forma Condensed Combined Financial Statements do not reflect any pro forma adjustments related to these amounts. BGE also has certain assets and liabilities for which amortization is recovered in regulated utility service rates but which do not earn a regulated return on investment. Because these assets and liabilities do not earn a regulated return on investment, the Unaudited Pro Forma Condensed Combined Financial Statements include pro forma adjustments to reflect these amounts at their estimated fair value.

The most significant pro forma adjustments include adjustments to reflect at fair value Constellation’s nonregulated property, plant and equipment—power generating assets and energy contracts. The most significant estimates that affect the fair values of these assets and liabilities as well as the magnitude of these adjustments are market prices for energy commodities, which are subject to extreme volatility over time. The effect of changes in energy market prices on the value of these assets and liabilities is interrelated and offsetting: the value of power generating assets is affected by the estimated cash flows that potentially could be realized from selling the power plants’ output in the market and generally increases when power prices increase; alternatively, the

152

value of energy contracts reflects commitments to sell power at specified prices that fix cash flows and generally decreases as power prices increase because of reduced opportunities to obtain the benefit of higher prices. Thus, increases in energy market prices have resulted in substantial and somewhat offsetting increases in the amounts under the associated captions in the Unaudited Pro Forma Condensed Combined Balance Sheet, which are summarized as follows:

Net adjustment to reflect fair value of nonregulated property, plant and equipment–power generating assets and energy contracts			$	1,636

The actual adjustments to reflect the fair value of these assets and liabilities at closing will depend upon many factors, including the level of market prices for energy commodities and the composition of Constellation’s contract portfolio at that time. The magnitude of the actual adjustments, as well as the relationship between the adjustments, likely will differ from the amounts summarized above, and such differences could be material. Additionally, the changes in the amounts reported in these balance sheet captions will be amortized into earnings of the combined company over different periods in the future. Generally, nonregulated property, plant and equipment-power generating assets will be amortized over the plants’ lives, which approximates 27 years, while derivative and unamortized energy contract liabilities will be amortized over the contracts’ remaining terms, which are substantially less than the plants’ remaining lives.

The table below summarizes certain of the pro forma adjustments affecting the Unaudited Pro Forma Condensed Combined Financial Statements, including the adjustments to nonregulated property, plant and equipment and energy contracts, as described above. As previously discussed, actual purchase price adjustments will be based on fair values at closing and could vary significantly due to various factors, including but not limited to, changes in the composition of Constellation’s assets and liabilities, market prices for energy and interest rates prior to completion of the merger. You should read this table along with the Notes to the Unaudited Pro Forma Condensed Combined Financial Statements and Constellation’s Quarterly Report on Form 10-Q for the three and six month periods ended June 30, 2006 and Annual Report on Form 10-K for the year ended December 31, 2005, both of which are incorporated by reference into this joint proxy statement/prospectus.

Combined Statements of Income

(a)

Historical Presentation—Certain reclassifications have been made to the historical presentation of FPL Group’s and Constellation’s financial statements in order to conform to the presentation used in the Unaudited Pro Forma Condensed Combined Statements of Income. These adjustments had no impact on the historical income from continuing operations.

(b)

Operating Revenues, Fuel and Purchased Energy Expenses—Represents the pro forma adjustments required to reflect the net incremental operating revenue, net incremental fuel and emission allowance expenses and net incremental gas storage expenses resulting from: (1) the amortization of the fair value adjustments related to certain of Constellation’s derivative and nonderivative energy purchases and sales, gas storage, fuel contracts, and gas transport contracts (see balance sheet Note (n)), (2) the amortization of the nuclear fuel adjustment to fair value (see balance sheet Note (g)), and (3) the adjustment of emission allowances to fair value, which increases the expense recognition of emission allowances consumed (see balance sheet Note (c)). Nuclear fuel and emission allowances are amortized on a units-of-production basis, while the energy contracts are being amortized over the remaining lives of the underlying contracts.

(c)

Operating Expenses-Pensions and Post-Retirement Benefits—Represents the pro forma adjustment required to reflect a decrease in net periodic pension and post-retirement benefit expense. The decrease is primarily a result of the elimination of the amortization of deferred gains and losses, unrecognized prior service costs and transition obligation due to the recording of the previously unrecognized portion of Constellation’s pension and/or post-retirement benefit obligations (see balance sheet Note (m)).

(d)

Operating Expenses-Stock-Based Compensation—Represents the pro forma adjustment required to reflect the application of SFAS No. 123R, Share-Based Payment, as if both companies adopted this accounting standard effective January 1, 2005. On a stand-alone basis, FPL Group adopted SFAS No. 123, Accounting for Stock-Based Compensation, on January 1, 2004 and SFAS No. 123R on January 1, 2006. Constellation adopted SFAS No. 123R on October 1, 2005.

(e)	Operating Expenses—Merger-Related Costs—Represents the pro forma adjustment to remove merger-related costs previously expensed by FPL Group and Constellation.

(f)

Depreciation, Depletion, Amortization and Accretion Expense—Represents the pro forma adjustment required to reflect the net incremental depreciation expense resulting primarily from the adjustment to record Constellation’s nonregulated property, plant and equipment at estimated fair value (see balance sheet Note (d)), and the additional accretion expense arising from the adjustment to record Constellation’s asset retirement obligations at estimated fair value (see balance sheet Note (l)). As discussed in balance sheet Note (d), the amount of the pro forma adjustment to depreciation expense is based on preliminary estimates of the fair values of the related assets, current depreciation methods and depreciation rates of approximately 3.6% per year. An increase (decrease) in the fair value of Constellation’s nonregulated property, plant and equipment of $100 million would result in an increase (decrease) to annual depreciation and amortization expense of approximately $3.6 million.

(g)

Interest Expense—Represents the pro forma adjustment to interest expense resulting from the adjustment to record Constellation’s third-party nonregulated debt at estimated fair value (see balance sheet Note (k)). The final fair value determination of the debt will be based on the credit rating of the underlying securities, the prevailing market interest rates at the completion of the merger, adjusted for estimated issuance costs, and the necessary adjustment will be amortized as a reduction (in the case of a premium to book value) or an increase (in the case of a discount to book value) to interest expense over the remaining life of the individual debt outstanding.

(h)

Intercompany Transactions—Represents the pro forma adjustments required to eliminate the effects of transactions between FPL Group and Constellation included in each company’s historical statements of income. The underlying amounts in these adjustments relate primarily to purchases and sales of power and

157

gas between the companies. The pro forma adjustments for intercompany transactions do not net to zero due to differing accounting designations by FPL Group and Constellation for certain derivative contracts. For example, for accounting purposes, Constellation may treat an energy sales contract with FPL Group as a cash flow hedge, while FPL Group may treat the same contract (the energy purchase contract with Constellation) as a derivative contract requiring mark-to-market accounting treatment.

(i)

Income Tax Expense—Represents the pro forma tax effect of the adjustments described above determined based on an estimated prospective statutory tax rate of approximately 40%, which reflects our best estimate of the combined company’s statutory income tax rates for all jurisdictions. This estimate could change based on changes in the applicable tax rates and finalization of the combined company’s tax position.

(j)

Earnings Per Share and Weighted-Average Shares Outstanding—The pro forma weighted-average number of basic and diluted shares outstanding is calculated by adding FPL Group’s weighted-average number of basic and diluted shares of common stock outstanding for the six months ended June 30, 2006 or for the year ended December 31, 2005, as applicable, and Constellation’s weighted-average number of basic and diluted shares of common stock outstanding for the same periods multiplied by 1.444, reflecting the stock split that will occur immediately prior to completion of the merger. The following table illustrates these computations:


Description	Six Months Ended June 30, 2006	Year Ended December 31, 2005

Combined Balance Sheet

(a)	Historical Presentation—Certain reclassifications have been made to the historical presentation of FPL Group’s and Constellation’s financial statements to conform to the presentation used in the Unaudited Pro Forma Condensed Combined Balance Sheet.

(b)

Goodwill—Under the terms of the merger agreement, immediately prior to the completion of the merger, Constellation will effect a stock split pursuant to which each share of Constellation common stock will be converted into 1.444 shares of Constellation common stock. Upon the completion of the merger, each share of FPL Group common stock outstanding immediately prior to the merger will be exchanged for one share of Constellation common stock, and FPL Group will be a wholly owned subsidiary of Constellation. Although Constellation will be issuing shares of Constellation common stock to FPL Group shareholders immediately prior to the merger, the merger will be accounted for as a reverse acquisition under the purchase method of accounting. Under the purchase method of accounting, FPL Group will be treated as the accounting acquiror and Constellation will be treated as the “acquired” company for financial reporting purposes because, upon completion of the merger, the FPL Group shareholders prior to the merger will have a majority of the voting interest in the combined company and a majority of the initial board of directors of the combined company will be designated by FPL Group.

Under the purchase method of accounting, the total consideration was determined using the average Constellation closing stock price over the period beginning two trading days before and ending two trading days after December 19, 2005, the date the acquisition was announced. The excess of purchase price over the book values of the assets deemed acquired and liabilities deemed assumed, is as follows ($ in millions):


Value of Constellation common stock issued	$	10,777
Value of Constellation stock compensation assumed		17
Estimated FPL Group transaction costs		40
Total value of preexisting contracts between FPL Group and Constellation		27

Total estimated purchase price		10,861
Less: Book value of Constellation assets deemed acquired and liabilities deemed assumed		(4,209	)

Excess of purchase price over net book value of assets deemed acquired	$	6,652

Under the purchase method of accounting, the total estimated purchase price, as shown in the table above, is allocated to Constellation’s net tangible and identifiable intangible assets deemed acquired and liabilities deemed assumed for purposes of preparing pro forma financial information based on their estimated fair values as of June 30, 2006. Final purchase price adjustments will be based on fair values at closing and could vary significantly from the pro forma amounts due to various factors, including but not limited to, changes in the composition of Constellation’s assets and liabilities, market prices for energy and interest rates prior to the completion of the merger. Accordingly, the fair value of these assets and liabilities is preliminary and is also subject to change pending additional information that may come to Constellation’s and FPL Group’s knowledge and restructuring decisions made upon completion of the merger. The preliminary adjustments to the assets deemed acquired and liabilities deemed assumed are as follows ($ in millions):

Excess of purchase price over net book value of assets deemed acquired	$	6,652
Adjustments to goodwill related to:
Inventories		(294	)
Regulatory assets		30
Intangible assets		(138	)
Nonregulated property, plant and equipment		(3,610	)

Nonregulated long-term debt, including elimination of deferred debt issuance costs		83
Deferred tax liabilities		710

Total adjustments		(1,064	)

Total adjustment to goodwill	$	5,588

Pursuant to SFAS No. 142, Goodwill and Other Intangible Assets, goodwill is not amortized; rather, impairment tests are performed at least annually or more frequently if circumstances indicate that an impairment may have occurred. If an impairment exists, the goodwill is immediately written down to its fair value through a current charge to earnings. Accordingly, the goodwill arising from the merger will be subject to an impairment test at least annually.

(c)

Inventories—Represents the pro forma adjustment required to record Constellation’s fuel stock and emission allowances at estimated fair value. The fuel stock and emission allowances adjustment was determined based on existing inventory levels and market information for allowances available through 2036 and, therefore, could be materially affected by changes in the market prices of fuel and emission allowances, as well as changes in the level of inventory held prior to the completion of the merger.

(d)

Nonregulated Property, Plant and Equipment—Represents the pro forma adjustment required to record Constellation’s nonregulated power generating assets at estimated fair value. The adjustment for nonregulated power generating assets was determined based on consideration of a discounted cash flow analysis using management’s view of the forward market curves for energy prices, comparable market transactions and replacement cost. These analyses are significantly affected by assumptions regarding the expected market prices for electricity, fuel and emission allowances, environmental regulation, operating costs, and the level of interest rates.

These pro forma adjustments, which have no impact to the combined company’s cash flows, would be depreciated using a rate of approximately 3.6% per year or $52 million for the six months ended December 31, 2006 and $125 million each year thereafter until fully depreciated and could be materially affected by changes in estimates of future capacity factors, operating costs, changes in NRC license extension assumptions and the expected market price for electricity, fuel and emission allowances prior to closing of the merger. Independent appraisals are expected to be completed subsequent to the closing of the merger.

(e)

Regulatory Assets—Represents the pro forma adjustment required to record certain of Constellation’s regulatory assets, which are not included in BGE’s rate base and are not earning a return, at estimated fair value. The adjustment was determined based on the present value of cash flows from the assets’ recovery in utility service rates under predetermined amortization schedules and will be amortized over the recovery period.

(f)

Intangible Assets—Represents the pro forma adjustment required to record Constellation’s identifiable intangible assets relating to a trade name at estimated fair value. The adjustment was determined based on discounted cash flow analysis. Other intangible assets have been evaluated and are described separately to

161

the extent an adjustment is required to reflect fair value. Those intangible assets identified include: nuclear fuel contracts (see Note (g)) and energy purchases and sales, gas storage and fuel contracts (see Note (n)).

(g)

Nuclear Fuel—Represents the pro forma adjustment required to record Constellation’s nuclear fuel inventory and purchase contracts at estimated fair value. The adjustment was determined based on nuclear fuel supply contracts previously entered into by Constellation with terms favorable to current market prices and the remaining quantity of fuel in the reactor or in-process of conversion, enrichment and fabrication. Accordingly, approximately $202 million of this adjustment was recorded as an increase to property, plant and equipment, net for fuel in the reactors or in-process of conversion, enrichment and fabrication. Approximately $128 million was recorded as an intangible asset within other noncurrent assets for nuclear fuel supply contracts. The intangible asset will be amortized on a units-of-production basis over the terms of the underlying contracts.

(h)	Derivative Assets and Unamortized Energy Contract Assets—Represents the pro forma adjustment to eliminate the valuation allowance previously recorded for origination gains associated with derivative contracts for which fair values were not observable.

(i)	Deferred Debt Issuance Costs—Represents the pro forma adjustment to adjust Constellation’s nonregulated debt to fair value.

(j)

Accrued Expenses and Other—Represents the pro forma adjustments related to transaction and employee retention costs incurred by Constellation that are directly attributable to the merger of approximately $29 million (an additional $26 million of costs were previously accrued by Constellation), as well as approximately $110 million related to Constellation’s stock-based compensation awards, the vesting of which will accelerate upon the completion of the merger and which will be settled in cash after the merger.

(k)

Nonregulated Long-Term Debt—Represents the pro forma adjustment required to record Constellation’s third-party debt related to its nonregulated operations at estimated fair value. The increase in the fair value of the debt will be amortized through interest expense over the remaining life of the debt. The final fair value determination will be based on the credit ratings of the underlying securities and prevailing market interest rates at the completion of the merger, adjusted for estimated issuance costs, and the necessary adjustment will be amortized as a reduction (in the case of a premium to book value) or an increase (in the case of a discount to book value) to interest expense over the remaining life of the individual debt outstanding.

(l)

Asset Retirement Obligations—Represents the pro forma adjustment required to record Constellation’s asset retirement obligations related to decommissioning its nuclear generating facilities at estimated fair value. The adjustment was determined based on differences between the discount rates originally used to record the obligations and current applicable discount rates. This adjustment could be materially affected by changes in interest rates, updated nuclear decommissioning cost studies, the timing and amount of actual cash flows and changes in management’s assumptions related to nuclear decommissioning. Since the fair value of the asset retirement obligation is determined using a present value approach, the accretion of the liability will be recognized until the liability is settled.

(m)

Pension and Post-Retirement Benefit Obligations—Represents the pro forma adjustment required to record Constellation’s pension and post-retirement benefit obligations to reflect the difference between the present value of the estimated accumulated obligations and the estimated fair values of any related plan assets, including elimination of the amortization of deferred gains and losses, unrecognized prior service cost and transition obligation, as well as the intangible asset related to the minimum pension liability.

The final determination of the pension and post-retirement benefit obligations adjustment may differ materially, mostly due to potential changes in discount rates which are affected by the level of interest rates, return on plan assets up to the date of completion of the merger, plan amendments, potential changes in pension and post-retirement accounting rules and the potential conforming of certain FPL Group and Constellation assumptions surrounding the determination of these obligations.

162

(n)

Energy Purchases and Sales, Gas Storage and Fuel Contracts—Represents the pro forma adjustment required to record, at estimated fair value, Constellation’s energy purchases and sales, fuel contracts and gas storage transport contracts that are not derivatives or are accounted for as “normal purchase, normal sale” transactions under SFAS No. 133. The adjustments have been presented as a net increase in current and noncurrent liabilities to reflect an approximation of the overall fair value of the portfolio of these contracts. The actual adjustments at the closing of the merger will be recorded as current and noncurrent assets and liabilities reflecting the actual composition of the portfolio and market prices for power and fossil fuels at that time after applying the netting provisions of FASB Interpretation No. 39, Offsetting of Amounts Related to Certain Contracts, to those values.

These adjustments will be amortized to earnings of the combined company based on the remaining lives of the underlying contracts in proportion to the fair value of the underlying cash flows. This amortization represents a non-cash change in revenues; therefore, cash flows from operations will not be affected by this amortization. Based upon the estimated fair value as of June 30, 2006, the amortization for the next five years would result in a decrease to revenues of $352 million for the six months ended December 31, 2006, and an increase to revenues of $629 million in 2007, $389 million in 2008, $344 million in 2009, $205 million in 2010 and $557 million thereafter. The adjustment reflects a non-cash decrease to revenues for the remainder of 2006 due to load-serving contracts where the price at which we are selling power is greater than the current market price. Thereafter, the adjustment results in a non-cash increase to revenues which declines over time as the remaining contracts deliver.

This adjustment could be materially affected by changes in the composition of the portfolio, as well as changes in prices of energy prior to closing. These factors have exhibited significant volatility in the past, and changes in one or more of these factors prior to closing of the merger could have a significant effect on the final determinations of fair value and the related amortization.

(o)

Deferred Income Taxes—The net non-current deferred tax liability represents the estimated impact on the allocation of purchase price to assets and liabilities. This estimate is based on an estimated prospective statutory tax rate of approximately 40% and could change based on changes in the applicable tax rates and finalization of the combined company’s tax position.

(p)

OTHER MATTERS TO BE CONSIDERED AT THE ANNUAL MEETINGS

CONSTELLATION PROPOSAL 3: ELECTION OF DIRECTORS

Vote Required; Recommendation of the Constellation Board of Directors

THE CONSTELLATION BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT CONSTELLATION STOCKHOLDERS VOTE FOR THE ELECTION OF EACH OF THE CONSTELLATION BOARD OF DIRECTORS’ NOMINEES. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED FOR EACH OF THE CONSTELLATION BOARD OF DIRECTORS’ NOMINEES.

Board Structure

The Constellation board of directors is divided into three classes (Class I, Class II and Class III), with one class of directors elected at each annual meeting of stockholders for a three-year term.

Sullivan for election as Class I directors at the annual meeting for terms of three years each and until their respective successors are duly elected and qualified.

Notwithstanding the election of the nominated directors at the annual meeting, if the merger with FPL Group is completed prior to the expiration of the term of such directors, the board of directors of the combined company from and after the completion of the merger will be determined in accordance with the merger agreement, as described under “The Proposed Merger—Post-Merger Governance and Management” beginning on page 145.

Determination of Independence

A majority of Constellation’s directors are required to be independent in accordance with New York Stock Exchange listing standards. For a director to be considered independent, the Constellation board of directors must affirmatively determine that such director has no material relationship with Constellation. When assessing the materiality of a director’s relationship with Constellation, the Constellation board of directors considers the issue from both the standpoint of the director and from that of persons and organizations with whom or with which the director has an affiliation. The Constellation board of directors has adopted standards to assist it in determining if a director is independent. A director shall be deemed to have a material relationship with Constellation and shall not be deemed to be an independent director if:

•

the director has been an employee of Constellation or any of its affiliated entities at any time since January 1, 2003, or an immediate family member of the director has been an executive officer of Constellation or any of its affiliated entities at any time since January 1, 2003; provided that employment of a director as an interim chairman of the Constellation board of directors or chief executive officer or other executive officer of Constellation shall not disqualify such director from being considered independent following termination of that employment;

•

the director or an immediate family member is a current partner of a firm that is Constellation’s internal or external auditor;

•

the director is a current employee of a firm that is Constellation’s internal or external auditor;

•

the director has an immediate family member who is a current employee of a firm that is Constellation’s internal or external auditor who participates in the firm’s audit, assurance or tax compliance (but not tax planning) practice;

•

the director or an immediate family member was at any time since January 1, 2003 (but is no longer) a partner or employee of a firm that is Constellation’s internal or external auditor and personally worked on Constellation’s audit within that time;

•

the director or an immediate family member, is, or has been at any time since January 1, 2003, employed as an executive officer of another company where any of Constellation’s present executive officers at the same time serves or served on that company’s compensation committee;

•

the director is a current executive officer or employee, or an immediate family member is a current executive officer, of another company that has made payments to, or received payments from (other than contributions to tax exempt organizations), Constellation for property or services in an amount which, in any of the other company’s last three fiscal years, exceeds the greater of $1.0 million or 2% of such other company’s consolidated gross revenues; or

•

the director has received, or has an immediate family member who has received, during any twelve-month period since January 1, 2003, more than $100,000 in direct compensation from Constellation, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided that such compensation is not contingent in any way on continued service); provided, however, that (i) compensation received by a director for former service as an interim chairman or chief executive officer or other executive officer need not be considered and (ii) compensation received by an immediate family member for service as an employee of Constellation (other than an executive officer) need not be considered.

The Constellation board of directors has determined that each member of the Constellation board of directors, other than Mr. Shattuck, who is the chief executive officer of Constellation, has no material relationship with Constellation and is independent under NYSE listing standards. In addition, the Constellation

166

Audit, Compensation and Nominating and Corporate Governance Committees are composed entirely of independent directors under NYSE listing standards, Securities and Exchange Commission requirements and other applicable laws, rules and regulations.

Meetings and Committees of the Constellation Board of Directors

The Constellation board of directors met seven times for regularly scheduled meetings and two times for special meetings in 2005. Each of the directors attended 75% or more of the total number of meetings of the board of directors and of any committees on which the director served.

The Constellation board of directors has the following committees:

Executive Committee: This committee may exercise all of the powers of the board of directors, except that it may not authorize dividends or the issuance of stock (except in certain limited circumstances authorized by the board of directors), recommend to stockholders any action requiring stockholder approval, amend the by-laws, or approve mergers or share exchanges that do not require stockholder approval. The committee met three times in 2005. Mr. Shattuck is Chairman, and Messrs. Crooke and Lawless are members.

Audit Committee: This committee oversees Constellation’s auditing, accounting, financial reporting, risk management, corporate compliance and internal control functions as set forth in its charter. The committee also approves the services provided by Constellation’s independent registered public accounting firm, and monitors and evaluates its performance, the fees paid, and the compatibility of the non-audit services provided by the firm with maintaining the firm’s independence. Each member of the committee is an “audit committee financial expert” as that term is defined in the applicable rules of the Securities and Exchange Commission, and “financially literate” as that term is defined in the listing standards of the New York Stock Exchange. Mr. Brady currently serves on the audit committees of three other public companies. The board of directors has determined that such service does not impair the ability of Mr. Brady to effectively serve on the committee. The committee met eight times in 2005. Mr. Brady is Chairman, and Messrs. Crooke and de Balmann are members. Frank F. Bramble, Sr., a Class I director until his resignation from the Constellation board of directors on August 10, 2006, was a member of the committee. Upon Mr. Bramble’s resignation, Mr. Crooke became a member of the committee.

Committee on Nuclear Power: This committee monitors the performance and safety at Constellation’s nuclear power plants. The committee met six times in 2005. Mr. Curtiss is Chairman, and Mr. Crooke, Ms. Lampton and Ms. Martin are members.

Compensation Committee: This committee reviews the recommendations of the Chief Executive Officer for candidates for positions as executive officers of Constellation and recommends candidates to the Constellation board of directors. It reviews and recommends to the Constellation board of directors compensation for directors, and establishes compensation and reviews perquisites and fringe benefits for the Chief Executive Officer and other executive officers. The committee approves the terms of any severance, change in control or employment contract for the Chief Executive Officer and other executive officers. The committee also oversees succession planning for the Chief Executive Officer and senior management. The committee met eight times in 2005. Mr. Lawless is Chairman, and Messrs. Becker and Sullivan, Dr. Hrabowski and Ms. Martin are members.

Nominating and Corporate Governance Committee: This committee considers and recommends to the Constellation board of directors nominees for election as directors, including nominees recommended by stockholders. It oversees corporate governance, Constellation board of directors composition, annual evaluations of the Constellation board of directors and its committees, and committee structure, membership and functions. The committee periodically reviews Constellation’s Corporate Governance Guidelines and Principles of Business Integrity. The committee met six times in 2005. Mr. Sullivan is Chairman, and Messrs. Becker and Lawless, Dr. Hrabowski and Ms. Martin are members.

Constellation maintains on its website, www.constellation.com, copies of the charters of each of the committees of the Constellation board of directors, as well as copies of its Corporate Governance Guidelines, Principles of Business Integrity, Corporate Compliance Program and Insider Trading Policy. Copies of these

167

documents are also available in print upon request of Constellation’s Corporate Secretary. The Principles of Business Integrity is a code of ethics which applies to all of our directors, officers and employees, including the chief executive officer, chief financial officer and chief accounting officer. Constellation will post any amendments to, or waivers of, the Principles of Business Integrity applicable to its chief executive officer, chief financial officer or chief accounting officer on its website.

In addition, the board of directors has designated the Chairman of the Nominating and Corporate Governance Committee to act as its “Lead Director.” In that capacity, the current Chairman, Mr. Sullivan, has the following duties and authority:

•

presiding at all meetings of the Constellation board of directors where the Chairman of the Board of Directors is not present;

•

serving as a liaison between the Chairman of the Board of Directors and the independent directors;

•

approving information sent to the Constellation board of directors, and agendas and meeting schedules for Constellation board of directors meetings;

•

calling meetings of independent directors;

•

chairing executive sessions of the independent members of the Constellation board of directors; and

•

serving as contact for stockholder complaints (other than auditing/accounting complaints, for which the Chairman of the Audit Committee is the contact for stockholders).

Interested parties may communicate directly with Mr. Sullivan in his capacity as Lead Director by writing to the Corporate Secretary, Constellation Energy Group, Inc., 750 East Pratt Street, 18th Floor, Baltimore, Maryland 21202, or by calling (877) 248-1476.

Nominations for Director

The Constellation board of directors seeks diverse candidates who possess the background, skills and expertise to make a significant contribution to the Constellation board of directors, Constellation and its stockholders. Annually, the Nominating and Corporate Governance Committee reviews the qualifications and backgrounds of the directors whose terms expire the next year, as well as the overall composition of the Constellation board of directors, and recommends to the full Constellation board of directors the slate of director candidates to be nominated for election at the next annual meeting of stockholders. The board of directors has adopted a policy whereby the Nominating and Corporate Governance Committee shall consider the recommendations of Constellation stockholders with respect to candidates for election to the board of directors and the process and criteria for such candidates shall be the same as those currently used by Constellation or otherwise suggested by the board of directors or management for director candidates recommended by the board of directors.

Constellation’s Corporate Governance Guidelines, a copy of which is maintained on our website, www.constellation.com, include the following criteria that are to be considered by the Nominating and Corporate Governance Committee and board of directors in considering candidates for nomination to the Constellation board of directors:

•

Experience, including leadership experience in business or administrative activities; breadth of knowledge about issues affecting Constellation and the industries/markets in which it operates; and the ability and willingness to contribute special competencies to Constellation board of directors activities.

•

Personal attributes, including unquestioned personal integrity; loyalty to Constellation and concern for its success and welfare; willingness to criticize and to apply sound business ethics and independent judgment; awareness of the director’s role in Constellation’s corporate citizenship responsibilities and image; availability for meetings and consultation on Constellation matters; broad contacts with relevant

168

business and political leaders; and willingness to assume broad stewardship responsibility on behalf of all constituents for the management of Constellation.

•

Each Constellation board of directors member is expected to devote sufficient time to carrying out Constellation board of directors duties and responsibilities effectively and should be committed to serve on the Constellation board of directors for an extended period of time.

•

Each Constellation board of directors member is expected to become a stockholder and have a financial stake in Constellation. In this regard, directors are required to, within five years of the later of (a) October 23, 2004, or (b) their initial appointment as a director of Constellation, own Constellation stock or deferred stock units with a value equal to at least five times the amount of their annual cash retainer for service as a director.

•

Qualified candidates for membership on the Constellation board of directors will be considered without regard to race, color, religion, sex, sexual orientation, ancestry, national origin or disability.

Each of the nominees for director proposed by the Constellation board of directors is a current director of Constellation, and, as discussed in Determination of Independence on page 166, all of them (other than Mr. Shattuck) have been determined by the Constellation board of directors to be independent under NYSE listing standards.

A stockholder who wishes to recommend to the Nominating and Corporate Governance Committee a nominee for director for the 2007 annual meeting of stockholders should submit the recommendation in writing to the Corporate Secretary, Constellation Energy Group, Inc., 750 East Pratt Street, 18th Floor, Baltimore, Maryland 21202.

Stockholder Communications

The Constellation board of directors has adopted a policy whereby any communications from stockholders of Constellation to the board of directors shall be directed to Constellation’s Corporate Secretary, who shall (i) determine whether any of such communications are significant, and promptly forward significant communications to the board of directors, and (ii) keep a record of all stockholder communications that the Corporate Secretary deems not to be significant and report such communications to the Constellation board of directors on a periodic basis, but not less frequently than quarterly.

A Constellation stockholder who wishes to communicate to the Constellation board of directors may submit such communication in writing to the Corporate Secretary, Constellation Energy Group, Inc., 750 East Pratt Street, 18th Floor, Baltimore, Maryland 21202, or call (877) 248-1476.

The Constellation board of directors has adopted a policy which encourages each director to attend the annual meeting of stockholders. Thirteen of the 14 directors in office as of the date of the 2005 annual meeting of stockholders attended the meeting.

Directors’ Compensation

Constellation does not pay directors who are also employees of Constellation or its subsidiaries for their service as directors. In 2005, non-employee directors received the following compensation:

•

$50,000 annual retainer, a $10,000 annual retainer for the audit committee chairman and a $5,000 annual retainer for each other committee chairman,

•

common stock award with a value of approximately $50,000, which stock is subject to pro rata forfeiture if Constellation board of directors service ceases during the year,

•

$1,250 fee for each regular or special Constellation board of directors or Constellation board of directors committee meeting attended, and

•

reasonable travel expenses to attend meetings.

169

Directors had the opportunity to elect to defer some or all of their retainers in deferred stock units or in a cash account, and to defer some or all of their fees in a cash account. Directors may also defer their common stock award in deferred stock units. Deferred stock units are bookkeeping entries that track the performance of Constellation common stock and are not actual shares of stock. The bookkeeping entries reflect Constellation common stock price changes, dividends, stock splits and other capital changes. At the end of their Constellation board of directors service, directors receive cash based on the value of their deferred stock units.

Under Constellation’s matching gifts program, Constellation will match up to $10,000 per year in contributions that each director makes to tax-exempt organizations.

Certain Relationships and Transactions

James R. Curtiss, a director of Constellation, is a partner in the law firm of Winston & Strawn. A subsidiary of Constellation paid fees to this firm for legal services rendered in 2005, and expects to pay fees for legal services in 2006.

Report of the Audit Committee

The role of the Audit Committee of the Constellation board of directors is to assist the board of directors in its oversight of Constellation’s responsibility relating to: (i) the integrity of Constellations’ financial statements; (ii) compliance with legal and regulatory requirements; (iii) the independent registered public accounting firm’s qualifications and independence; (iv) the performance of Constellation’s internal auditors and independent registered public accounting firm; (v) risk assessment; and (vi) risk management. We operate pursuant to a charter that was last amended and restated by the Constellation board of directors in October 2005, a copy of which is attached hereto as Annex H to this joint proxy statement/prospectus. Management of Constellation is responsible for the preparation, presentation and integrity of Constellation’s financial statements, accounting and financial reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for auditing Constellation’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and expressing an opinion as to their conformity with accounting principles generally accepted in the United States. The independent registered public accounting firm has free access to the Audit Committee to discuss any matters they deem appropriate.

In the performance of our oversight function, we have considered and discussed the audited financial statements with management and the independent registered public accounting firm. We rely without independent verification on the information provided to us and on the representations made by management and the independent registered public accounting firm. We have discussed with the independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as currently in effect. Finally, we have received the written disclosures and the letter from the independent registered public accounting firm required by the Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, as currently in effect, and have considered whether the provision of non-audit services by the independent registered public accounting firm to Constellation is compatible with maintaining the independent registered public accounting firm’s independence and have discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence.

Based upon the reports and discussions described in this report, we recommended to the Constellation board of directors that the audited financial statements be included in Constellation’s Annual Report on Form 10-K for the year ended December 31, 2005 filed with the Securities and Exchange Commission.

Long-Term Incentive Plan Awards Table

Target awards of performance units were made for the three-year performance period that began January 1, 2005 pursuant to Constellation’s Executive Long-Term Incentive Plan. Each performance unit is equivalent to one dollar ($1.00). The value of the performance unit award payouts is dependent on Constellation’s total shareholder return for the three-year performance period relative to the total shareholder return of either investment grade large- and mid-cap companies in the Dow Jones Electricity and Multiutilities Indexes or companies in the S&P 500 Index. The performance measures used to determine the performance unit award payouts are discussed in additional detail in the Report of Compensation Committee on Executive Compensation on page 182. After the end of the three-year performance period, awards will be paid out 50% in cash and 50% in cash or equity at the discretion of the Compensation Committee.

177

The following table reports potential payouts of performance units awarded to the persons named in the 2005 Summary Compensation Table on page 172. The threshold, target and maximum awards are equal to 50%, 100% and 200%, respectively, of the performance unit target award, for the Dow Jones Electricity and Multiutilities Indexes measure and 50%, 75% and 150%, respectively, of the performance unit target award, for the S&P 500 Index measure. Payouts are interpolated between award levels.

Pension Benefits

Mr. Shattuck and Ms. Smith participate in the Senior Executive Supplemental Plan. Under the plan, at retirement a participant must be at least age 55 with 10 or more years of vesting service or at least age 62 with five or more years of vesting service to be entitled to any benefits. Benefits paid before age 62 are reduced for early receipt. Mr. Shattuck’s normal retirement annuity benefit under the plan, which is available at age 62 with five or more years of vesting service, will be computed at 60% of covered earnings. At December 31, 2005, based on his current age of 51 and four years and two months of vesting service, Mr. Shattuck was not eligible for benefits under the plan as he did not meet the age and service requirements.

Normal retirement annuity benefits available under the plan at age 62 for Ms. Smith accrue at 5.5% per year of benefit service, up to a maximum annuity benefit of 55% of covered earnings. At December 31, 2005, based on her current age of 46 and four years and seven months of vesting service, Ms. Smith was not eligible to receive benefits under the plan as she did not meet the age and service requirements. As of that date, she has accrued benefits equal to 25.2% of covered earnings, which would be available at age 62 if she meets the service requirement.

Covered earnings are equal to the average of the highest two of the last five years’ base pay amounts plus the average of the highest two of the last five years’ annual incentive award amounts. Benefits payable under the plan are paid in periodic installments unless a participant elects a lump sum. Plan participants are entitled to a 50% survivor annuity benefit at no cost. The benefits computed under the Senior Executive Supplemental Plan will be offset by benefits under the qualified employee pension plan applicable to most employees but will not be offset for Social Security.

Normal retirement annuity benefits are available at age 62 under the Supplemental Pension Plan and are computed as a percentage of covered earnings. Covered earnings are equal to the prior year base salary plus average annual incentive (highest two of the last five years’ annual incentive award percentages multiplied by base pay at the end of the prior year). Benefits accrue under the plan based on years of service ranges. Under the plan, at retirement a participant must be at least age 55 with 10 or more years of service or at least age 62 with one or more years of service. Benefits paid before age 62 are reduced for early receipt. Benefits payable under the plan are paid in periodic installments unless a participant elects a lump sum. Plan participants are entitled to a 50% survivor annuity benefit at no cost. The benefits computed under the Supplemental Pension Plan will be offset by the benefit under the qualified employee pension plan applicable to most employees but will not be offset by Social Security. None of the persons named in the 2005 Summary Compensation Table beginning on page 172 participates in the Supplemental Pension Plan.

178

Vesting of accrued benefits under the Senior Executive Supplemental Plan and the Supplemental Pension Plan accelerates when any of these events occur: employment termination, demotion or loss of benefit eligibility without cause; a change in control of Constellation followed within two years by the executive’s demotion, employment termination or loss of benefit eligibility; or reduction of previously accrued benefits. As a result of such accelerated vesting, the executive would be entitled to a lump sum payout of the vested amount from the applicable pension plan after employment termination. For a description of how benefits under these plans would be affected by the merger, see “Additional Interests of Constellation’s Directors and Executive Officers—Payments Due Upon a Termination of Employment—Potential Enhanced Supplemental Retirement Benefits” beginning on page 121.

Mr. Brooks’, Mr. Dawson’s and Mr. Persky’s normal retirement lump sum benefits, which are available at age 65 under the Benefits Restoration Plan, accrue in accordance with the benefit formula of the qualified employee pension plan but without regard to Internal Revenue Service limitations. Under the plan, a lump sum benefit is computed based on covered earnings multiplied by a total credit percentage. Covered earnings are equal to the average of the highest three of the last five years’ base pay plus annual incentive. The total credit percentage is equal to the sum of the credit percentages based on the following formula—5% per year of service through age 39, 10% per year of service from age 40 to age 49, and 15% per year of service after age 49. Mr. Brooks’, Mr. Dawson’s and Mr. Persky’s lump sum benefits under the plan at normal retirement age 65 will total 341%, 362% and 371%, respectively, of final average salary and bonus, and will be offset by the benefits under the qualified employee pension plan applicable to most employees, but will not be offset by Social Security. No benefits are available under the plan until a participant has at least five years of service. At December 31, 2005, Mr. Brooks was age 43 and had four years and nine months of service, Mr. Dawson was age 38 and had four years and nine months of service and Mr. Persky was age 35 and had four years and nine months of service. Benefits payable under the plan are paid in periodic installments unless a participant elects a lump sum.

If Mr. Shattuck or Ms. Smith terminate employment after five years of service but prior to meeting the eligibility requirements for benefits under the Senior Executive Supplemental Plan, (i.e., before reaching age 55 with 10 or more years of vesting service or age 62 with five or more years of vesting service), they would be eligible to receive benefits under the Benefits Restoration Plan calculated in the same manner as described above with respect to Messrs. Brooks, Dawson and Persky. At December 31, 2005, Mr. Shattuck was age 51 and had four years and two months of service and Ms. Smith was age 46 and had four years and seven months of service.

Under the Supplemental Benefits Plan, each executive is also entitled to personal financial, tax and estate planning benefits that continue during the year of retirement plus the next two calendar years. If a retired executive continues to serve as a member of the Constellation board of directors, the personal financial, tax and estate planning benefit period extends until Constellation board of directors membership ceases.

Covered earnings used to compute pension benefits for the individuals named in the 2005 Summary Compensation Table beginning on page 172 as of December 31, 2005 were as follows:


M. A. Shattuck III	$	4,486,000
T. V. Brooks		3,133,300
E. F. Smith		1,986,500
F. J. Dawson		400,000

Constellation sponsors the Nonqualified Deferred Compensation Plan that provides the opportunity for eligible employees including the individuals named in the 2005 Summary Compensation Table on page 172 to defer certain compensation including base salary and annual incentives. Under the plan, Constellation matches base salary deferral amounts for salary over the Internal Revenue Service compensation limit (applicable to qualified employee 401(k) plans) using the same matching formula as under the Constellation qualified employee

179

401(k) plan (match of 50% up to the first 6% of employee salary deferral). Nonqualified Deferred Compensation Plan participants may elect to invest their plan account balances in investment options that substantially mirror the qualified employee 401(k) plan options. Plan participants do not pay taxes on amounts deferred, company contributions, or earnings thereon, until amounts are distributed from the Nonqualified Deferred Compensation Plan. An executive’s benefits under the Nonqualified Deferred Compensation Plan always are fully vested and are payable after employment termination.

Constellation previously funded a rabbi trust to secure benefits accrued through December 31, 2002 under the Senior Executive Supplemental Plan and the Supplemental Pension Plan. Constellation’s last contribution to the trust was made during 2003. Constellation currently funds a rabbi trust for the Nonqualified Deferred Compensation Plan. Contributions to the trust include the amount of participant deferred compensation and employer matching contributions. These rabbi trusts do not increase the amount of supplemental pension benefits or deferred compensation. Following completion of the merger with FPL Group, the rabbi trusts cannot be amended for two years, the trustees may not be removed for two years and a reversion of excess trust assets cannot be taken for two years.

A copy of the following Constellation plans may be found in Constellation’s reports as follows: Senior Executive Supplemental Plan—Exhibit 10(e) to the Quarterly Report on Form 10-Q for the quarter ended March 31, 2004; Supplemental Pension Plan—Exhibit 10(d) to the Quarterly Report on Form 10-Q for the quarter ended March 31, 2004; Benefits Restoration Plan—Exhibit 10(m) to the Annual Report on Form 10-K for the year ended December 31, 2001; Supplemental Benefits Plan—Exhibit 10(p) to the Annual Report on Form 10-K for the year ended December 31, 2001; and Nonqualified Deferred Compensation Plan—Exhibit 10(c) to the Annual Report on Form 10-K for the year ended December 31, 2002.

Merger with FPL Group

The completion of the merger with FPL Group will constitute a change in control under Constellation’s equity plans and supplemental pension plans. This may accelerate benefits payable to the named executive officers under certain circumstances as described in this joint proxy statement/prospectus under “The Proposed Merger—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger” beginning on page 113.

Severance, Employment and Other Agreements

As discussed in this joint proxy statement/prospectus under “The Proposed Merger—Additional Interests of Constellation’s Directors and Executive Officers in the Merger—Payments Due Upon a Termination of Employment—Amended and Restated Change in Control Severance Agreements” beginning on page 120, Constellation has entered into change in control severance agreements with certain executive officers, including Messrs. Shattuck and Brooks and Ms. Smith.

In December 2005, Constellation and Mr. Shattuck entered into an employment agreement relating to his employment by Constellation following the consummation of the merger with FPL Group. In April 2006, Mr. Shattuck waived his right under the employment agreement to receive an enhanced cash severance payment upon termination of his employment during the term of the agreement. This employment agreement is described in this joint proxy statement/prospectus under “The Proposed Merger—Additional Interests of FPL Group’s and Constellation’s Directors and Executive Officers in the Merger—New Employment Agreement with Mr. Shattuck” beginning on page 128.

In July 2004, Ms. Smith entered into an employment agreement with Constellation for an initial term of three years. Each July 1, beginning July 1, 2005, the agreement is extended automatically for an additional one year unless one party provides written notice to the other not to so extend. The term of the employment agreement has been extended until July 1, 2009. Under the terms of the agreement, Ms. Smith serves as

180

Executive Vice President, Chief Financial Officer and Chief Administrative Officer of Constellation at a minimum annual base salary of $500,000. During the term of the agreement, Ms. Smith’s annual incentive opportunity target will be 100% of annual base salary, with a minimum annual opportunity of 0% of annual base salary and a maximum annual opportunity of 300% of annual base salary, based on Constellation and individual performance. The agreement also provides for an annual grant of a long-term incentive opportunity with a value at grant of $1,000,000 and an annual grant of service-based restricted stock with a value of $500,000 with three-year ratable vesting. In the event of termination of Ms. Smith’s employment by Constellation without cause or Ms. Smith’s resignation from employment with Constellation for good reason, Ms. Smith will receive (a) the portion of her annual base salary that has been earned but not yet paid, (b) a pro-rated annual incentive award paid at target, (c) a lump sum cash payment of $4,500,000, (d) accelerated vesting of non-performance-based equity awards, (e) payment of any performance-based equity award earned by Ms. Smith under a long-term incentive plan based on Constellation’s performance when such awards are payable to other participants, (f) health and dental benefits under Constellation’s employee plans or substantially equivalent benefits for the remainder of the then current term of the employment agreement or, if later, two years from the date of termination and (g) 60 days of outplacement services at a cost not to exceed $50,000. Ms. Smith is required to release Constellation and its subsidiaries from legal claims as a condition to receiving the benefits.

Ms. Smith’s employment agreement supersedes any prior agreements between her and Constellation except her change in control severance agreement. In the event Ms. Smith is entitled to payments under both the employment agreement and the change in control severance agreement, she will receive payments and benefits under the agreement most beneficial to her.

Report of Compensation Committee on Executive Compensation

Compensation Committee

The Compensation Committee of the Constellation board of directors is responsible for executive compensation policies. We also approve all compensation and benefit plans, specific salary amounts, and other compensation awards for individual executive officers. All of our Committee members are independent directors.

Philosophy

We design compensation policies to encourage executives to manage Constellation in the best long-term interests of its stockholders and to enable Constellation to attract and retain highly motivated executives with outstanding skills and who are best suited to drive its success over the long term. The Committee has retained an outside executive compensation consultant as our advisor in the areas of executive compensation and benefits.

The Committee references Constellation’s comparative labor markets for the purposes of establishing executive compensation and benefits. The applicable labor markets correspond with Constellation’s executive hiring experience, and include companies whose executives have similar roles and responsibilities and are representative of industries relevant to Constellation’s businesses. Peer groups are reflective of the industries and labor markets in which Constellation competes for executives, and general industry companies of similar size to Constellation.

The elements of executive compensation are:

•

base salary,

•

short-term incentive awards, and

•

long-term incentive awards.

182

The Committee’s philosophy is that base salary should be linked to the median level of the relevant labor market. The aggregate of an executive’s base salary and target short-term incentive awards should approximate the median level of the relevant labor market for average performance, and base salary and actual short-term incentive award payouts should approximate the 75th percentile for superior personal and company performance. Long-term incentive award grants should bring target total direct compensation to approximately the 50th percentile of the relevant labor market. Under this approach, a high proportion of executive compensation is “at risk” in the form of short- and long-term incentive opportunities. As described below, staff and business unit and individual performance are among the criteria we use in determining base salary, and are key components in determining both short-term and long-term incentive awards. Also, stock-based compensation such as stock options and restricted stock link a significant portion of long-term compensation to stock price appreciation realized by all Constellation stockholders.

In addition, executives receive various company-provided perquisites. The Committee reviewed the type and level of perquisites provided to executive officers, and determined that the perquisites provided during 2005 were reasonable. During 2005, the incremental cost to Constellation of the perquisites provided to any executive officer did not exceed $50,000.

The Committee has also established stock ownership guidelines for Constellation’s executives. The guidelines seek to align the interests of these executives with the interests of stockholders, by encouraging long-term value creation by requiring each executive to acquire holdings of Constellation stock with a value equal to established multiples of base salary. For those executives who are members of Constellation’s executive management committee, the stock ownership guidelines are:


• Chief Executive Officer		7 times base salary
• Executive Vice Presidents		5 times base salary
• Senior Vice Presidents		3 times base salary

Under the guidelines, Messrs. Brooks, Dawson and Persky are required to acquire holdings of Constellation stock with a value equal to the average of their base salary plus short-term incentive awards plus long-term incentive awards over the prior three years.

Annual Cash Compensation

Base Salary. We used compensation data developed by well recognized compensation consulting firms, the Committee’s compensation philosophy and our assessment of individual, staff and business unit performance to determine base salary increases for executives in 2005. Mr. Shattuck’s 2005 base salary was unchanged from 2004 remaining at $1 million.

Short-Term Incentives. Bonus payments under the 2002 Executive Annual Incentive Plan approved by stockholders in 2002 (the “Executive Annual Incentive Plan”) for Mr. Shattuck and other executives represent the short-term incentive component of executive compensation. The Committee considered bonuses for Mr. Shattuck and the other executives based on achievement of corporate financial and business plan objectives, and individual performance.

At the beginning of 2005, the Committee determined the appropriate short-term incentive amount at target performance for each executive except Messrs. Brooks, Dawson and Persky. The Committee then established annual incentive performance metrics for different 2005 adjusted earnings per share ranges for each level of performance. The Committee also established the maximum annual incentive award opportunity available to each executive including Messrs. Brooks, Dawson and Persky.

Constellation’s 2005 adjusted earnings per share was in excess of the target performance level established by the Committee at the beginning of the year. Compared to 2004, adjusted earnings per share was up 16%,

183

exceeding the top end of Constellation’s guidance. In determining actual bonus payments to be made to each executive, the Committee also assessed individual and business and staff unit performance against the pre-established quantitative and qualitative measures, and also took into account the following accomplishments: Constellation’s superior earnings growth rate compared to comparable companies; Constellation’s wholesale competitive supply business had a strong year with new origination up 99% driven by strong portfolio management and trading performance and a prospering coal and gas business; Constellation’s generation business and corporate staff realized productivity benefits of $90 million, $10 million over the pre-established target; the further strengthening of Constellation’s balance sheet by continued reduction of the debt to capital ratio; Constellation was named the Most Admired Energy Company in North America by FORTUNE Magazine, received the 2005 Edison Award from the Edison Electric Institute, the power industry’s highest honor, and ranked as the top utility in Business Week’s annual evaluation of the best performing companies in the S&P 500 stock index. Based on this review, the Committee authorized bonus payments for 2005 performance to Mr. Shattuck and the other named executives, as shown in the column in the 2005 Summary Compensation Table beginning on page 172 titled Annual Compensation—Bonus.

Long-Term Incentives

The Constellation Executive Long-Term Incentive Plan allows various types of awards that are linked to corporate performance, including stock options as well as restricted stock, restricted stock units and performance units subject to performance-based contingencies. Outstanding grants under the Plan include performance-based restricted stock, performance units and stock options. The value of these long-term incentive grants correlates to future performance, as performance-based restricted stock and performance unit grants are subject to forfeiture if performance criteria are not satisfied and stock options provide value to the executive only to the extent the market price of Constellation common stock appreciates over the option term. Most grants are subject to forfeiture if the executive’s employment terminates for certain reasons during the applicable performance period.

2005 Grants. In February 2005, the Committee made grants to Mr. Shattuck and certain other executives under the Executive Long-Term Incentive Plan at levels designed to provide appropriate long-term performance incentives. The amount of the grants made to each executive was determined taking into account market compensation data, corporate, business and staff unit and individual performance. The grants consisted of the following:

•

50% of the grant value was delivered in non-qualified stock options with ratable vesting over three years. Awards become exercisable in three equal annual installments on February 24, 2006, February 24, 2007 and February 24, 2008. These options provide a reward for stock price appreciation over a long-term period of up to 10 years, seeking to align the interests of the executives with those of stockholders. The options granted are included in the column of the 2005 Summary Compensation Table beginning on page 172 titled Long-Term Compensation—Securities Underlying Options and in the Option Tables beginning on page 172.

•

The remaining 50% of the grant value was delivered in the form of performance units that vest at the end of the three-year performance period. The performance units were granted at target and are paid out only if Constellation meets performance objectives established by the Committee. The primary performance criteria is Constellation’s 2005-2007 total shareholder return (TSR) relative to investment grade large- and mid-cap companies in the combined Dow Jones Electricity and Multiutilities Indexes. If Constellation’s TSR is below a minimum threshold during the performance period, then Constellation’s TSR will be measured against the TSR of companies in the S&P 500 Index. The potential payouts of performance units to Mr. Shattuck and certain other executives under the primary and secondary performance measures are shown in the Long-Term Incentive Plan Awards Table beginning on page 177.

Also in February 2005, the Committee made grants of service-based restricted stock under Constellation’s long-term incentive plans to certain named executive officers, which vest ratably over three years. Dividends are automatically reinvested. The dollar value of the restricted stock granted is shown in the column of the 2005

184

Summary Compensation Table beginning on page 172 titled Long-Term Compensation—Restricted Stock Awards beginning on page 172.

In December 2005, the Committee requested four executive officers, including Messrs. Shattuck and Brooks and Ms. Smith, to exercise all vested options held by them, including options to purchase 550,000 shares held by Mr. Shattuck for which the Committee accelerated vesting, for purposes of minimizing the amount of excise taxes and tax gross-up which might be payable by Constellation on behalf of each executive officer pursuant to Section 4999 of the Internal Revenue Code. Following the exercise of such vested options, the Committee granted replacement options to each of the executive officers that are fully vested, have an exercise price equal to the fair market value of Constellation common stock on the date of grant and retain the expiration date of the options that were replaced. The number of replacement options is equal to the actual options exercised, less the number of shares of common stock actually delivered to the executive officer net of tax withholding. Each executive officer continues to hold all the resulting value realized upon the exercise of such officer’s vested options in shares of Constellation common stock. The replacement options granted are included in the column of the 2005 Summary Compensation Table beginning on page 172 entitled Long-Term Compensation—Securities Underlying Options. The option exercises and replacement option grants also are included in the Option Tables beginning on page 176.

Merger with FPL Group

In December 2005, the Committee reviewed and approved an employment agreement between Constellation and Mr. Shattuck relating to Mr. Shattuck’s employment by Constellation following the merger with FPL Group, which will become effective upon the completion of the merger. The employment agreement with Mr. Shattuck is described in this joint proxy statement/prospectus under “The Proposed Merger—Additional Interests of Constellation’s Directors and Executive Officers in the Merger” beginning on page 120.

Policy Concerning $1 Million Deduction Limitation

Section 162(m) of the Internal Revenue Code limits to $1 million the tax deduction of public companies for compensation paid to their chief executive officers and the four other most highly compensated executive officers. There are several exemptions to Section 162(m), including one for qualified performance-based compensation. To be qualified, performance-based compensation must meet various requirements, including stockholder approval. Our Committee’s general intent is to design and administer the executive compensation programs in a manner that will preserve the deductibility of compensation payments to executive officers. However, this goal is secondary in importance to achievement of our compensation philosophy discussed earlier in this report, including managing Constellation in the best long-term interests of its stockholders. We previously adopted, and our stockholders approved, the Executive Annual Incentive Plan and the Executive Long-Term Incentive Plan in order to meet the performance-based qualification under the Internal Revenue Code. While we adopted the above-mentioned plans, we feel it is appropriate to maintain the flexibility of our Committee to exercise judgment in assessing an executive’s performance in order to achieve the desired compensation objectives, which may result in certain nondeductible compensation payments from time to time.

Section 16(a) Beneficial Ownership Reporting Compliance

Constellation’s directors and executive officers are required to file initial reports of ownership and reports of changes of ownership of Constellation common stock with the Securities and Exchange Commission. Based upon a review of these filings and written representations from the Constellation directors and executive officers, all required filings were timely made in 2005.

CONSTELLATION PROPOSAL 4: RATIFICATION OF PRICEWATERHOUSECOOPERS LLP AS CONSTELLATION’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2006

Vote Required; Recommendation of the Constellation Board of Directors

THE CONSTELLATION BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT CONSTELLATION STOCKHOLDERS VOTE FOR APPROVAL OF THIS PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED FOR APPROVAL OF THIS PROPOSAL.

General

The Audit Committee of the Constellation board of directors has appointed PricewaterhouseCoopers LLP as the independent registered public accounting firm of Constellation for the fiscal year ending December 31, 2006. PricewaterhouseCoopers LLP has been Constellation’s independent auditors since 1941. A member of PricewaterhouseCoopers LLP will be at the annual meeting and will have the opportunity to make a statement and answer appropriate questions. If the stockholders fail to ratify PricewaterhouseCoopers LLP as the independent registered public accounting firm, the Audit Committee will reconsider its selection.

Fees

Below is a breakdown of fees paid to PricewaterhouseCoopers LLP in 2004 and 2005:


	Audit Fees		Audit-Related Fees		Tax Fees		All Other Fees
2004	$	7,752,473	$	1,081,097	$	72,977	$	0
2005	$	6,606,982	$	567,707	$	74,250	$	0

The “Audit Fees” category includes approximately $3.9 million and $2.7 million for 2004 and 2005, respectively, of fees paid to PricewaterhouseCoopers LLP in connection with its performance of Sarbanes-Oxley Section 404 attestation procedures. The “Audit-Related Fees” category for 2004 includes approximately $0.8 million of advisory services with respect to preparing for Sarbanes-Oxley Act Section 404 attestation. The “Audit-Related Fees” category for 2004 and 2005 also includes fees paid in connection with other services related to our annual audit and interim reviews including statutory audits and, for 2005, services related to the merger with FPL Group. The “Tax Fees” category consists, for 2004 and 2005, of fees paid in connection with executive tax services.

Policy for Approval of Audit and Permitted Non-Audit Services

The Audit Committee is responsible for the appointment, compensation, and oversight of the work of Constellation’s independent registered public accounting firm. As part of this responsibility, the Audit Committee has adopted an Audit and Non-Audit Pre-Approval Policy, which sets forth the procedures and the conditions pursuant to which services proposed to be performed by the independent registered public accounting firm must be approved. All services to be provided by the independent registered public accounting firm as well as the related fees must be pre-approved by the Audit Committee and all such services and fees were pre-approved in 2004 and 2005. The Chairman of the Audit Committee has been delegated the authority to specifically pre-approve services, which pre-approval is subsequently reviewed with the Committee. In no event

186

may pre-approval authority be delegated to Constellation management. In the course of carrying out its responsibilities, the Audit Committee considers whether services proposed to be performed by the independent registered public accounting firm are consistent with the rules promulgated by the Securities and Exchange Commission on auditor independence. The Audit Committee also considers the independent registered public accounting firm’s familiarity with Constellation’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance Constellation’s ability to manage or control risk or improve audit quality.

CONSTELLATION PROPOSAL 5: STOCKHOLDER PROPOSAL

Vote Required; Recommendation of the Constellation Board of Directors

Approval of the stockholder proposal requires the affirmative vote of a majority of the votes cast by holders of shares of Constellation common stock present in person or by proxy at the meeting and entitled to vote, assuming a quorum is present. Abstentions and “broker non-votes” have no effect on this proposal, except they will be counted as having been present for purposes of determining the presence of a quorum. See “Information About the Annual Meetings and Voting” beginning on page 36.

THE CONSTELLATION BOARD OF DIRECTORS MAKES NO VOTING RECOMMENDATION WITH RESPECT TO THIS PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE COUNTED AS ABSTENTIONS.

General

Constellation has been advised by the International Brotherhood of Electrical Workers Pension Benefit Fund, 900 Seventh Street, N.W., Washington, DC 20001, that it holds 4,033 shares of common stock and that the following proposal will be presented for action at the annual meeting:

RESOLVED, That the shareholders of Constellation Energy Group Inc. (“Company”) urge that the Board of Directors take the necessary steps to declassify the Board of Directors for the purpose of establishing annual elections for directors. The Board of Directors declassification shall be done in a manner that does not affect the unexpired terms of directors previously elected.

Stockholder’s Supporting Statement

We believe the election of directors is the primary avenue for shareholders to influence corporate governance policies and to hold management accountable for its implementation of those policies. We believe that classification of the board of directors, which results in only a portion of the board being elected annually, is not in the best interests of our Company and its stockholders for the following reasons.

Constellation Energy Group’s board of directors is divided into three classes, with approximately one-third of all directors elected annually to three-year terms. Eliminating this classification system would require each director to stand for election annually, which we believe would give stockholders an opportunity to register their views on the performance of the board collectively and each director individually.

We believe that electing directors annually is one of the best methods available to stockholders to ensure that Constellation Energy Group, Inc. is managed in the best interests of stockholders. A study by researchers at Harvard Business School and the University of Pennsylvania’s Wharton School titled “Corporate Governance and Equity Prices” (Quarterly Journal of Economics, February 2003) looked at the relationship between corporate governance practices (including classified boards) and firm performance. The study found a significant positive link between governance practices favoring shareholders (such as annual director elections) and firm value, though the study did not break out the impact of individual governance practices.

187

In our view, annual director elections is a growing trend. In 2005, according to IRRC, more than 30 companies - including Raytheon, Prudential Financial, Northrop Grumman, and Goldman Sachs - sought and received shareholder approval to declassify their boards. This number was up sharply from the previous year.

We regard as unfounded the concern expressed by some that the annual election of all directors could leave companies without experienced directors in the event that all incumbents are voted out by stockholders. In the unlikely event that stockholders do vote to replace all directors, such a decision would express dissatisfaction with the incumbent directors and would reflect the need for change.

We urge you to vote FOR this resolution.

Constellation Board of Directors’ Position on Stockholder Proposal

The Constellation board of directors has considered the proposal set forth above relating to declassifying the board of directors and has determined not to oppose the proposal and to make no voting recommendation on the proposal to stockholders. In doing so, the Constellation board of directors notes that stockholders are being asked in this joint proxy statement/prospectus to approve a charter amendment, to take effect upon completion of Constellation’s merger with FPL Group, that will, among other things, declassify the board of directors. Constellation is working to complete the merger by the end of 2006 or the first quarter of 2007, and if the merger is completed by then, directors will stand for annual election beginning with Constellation’s 2007 annual meeting of stockholders.

Approval of this stockholder proposal would not automatically eliminate Constellation’s classified board structure. However, if stockholders approve this proposal and the merger with FPL Group is not completed before the 2007 annual meeting of stockholders, the Constellation board of directors, to the extent consistent with its fiduciary duty to act in a manner it believes to be in the best interests of Constellation and its stockholders, will abide by the vote of stockholders and will present for a vote of stockholders at the 2007 annual meeting an amendment to the Constellation charter that, if approved, would eliminate the classified board structure.

This proposal will not be approved unless it receives the affirmative votes of the holders of a majority of the votes cast on such proposal. Abstentions and broker non-votes will not be counted as either for or against the proposal. If not otherwise specified, proxies will be counted as abstentions.

188

FPL GROUP PROPOSAL 2: ELECTION OF DIRECTORS

Vote Required; Recommendation of the FPL Group Board of Directors

FPL Group directors are elected by the affirmative vote of a majority of the total number of shares represented at the meeting and entitled to vote for the election of directors, assuming a quorum is present.

Abstentions and votes to withhold have the same effect as a vote against the election of a director, and broker non-votes have no legal effect. See “Information About the Annual Meetings and Voting” beginning on page 36.

THE FPL GROUP BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT FPL GROUP SHAREHOLDERS VOTE FOR THE ELECTION OF EACH OF THE FPL GROUP BOARD OF DIRECTORS’ NOMINEES.

Performance Graph

The graph below compares the cumulative total returns, assuming reinvestment of dividends, of FPL Group common stock with the companies in the Standard & Poor’s 500 Index (S&P 500), the Standard & Poor’s Electric Utilities Index (S&P Electrics) and the Dow Jones US Electric Utilities Index (Dow Jones Electrics). The comparison covers the five years ended December 31, 2005, and is based on an assumed $100 investment on December 31, 2000, in each of the S&P 500, the S&P Electrics, the Dow Jones Electrics and FPL Group common stock. The S&P Electrics is based on the performance of 12 companies and the Dow Jones Electrics is based on the performance of 43 companies. The S&P Electrics is more heavily weighted toward companies engaged, to a significant extent, in the traditional state-regulated electric utility business. The Dow Jones Electrics, which includes all of the companies included in the S&P Electrics, also includes a number of companies that are exclusively or primarily engaged in the competitive energy business. FPL Group is primarily engaged in the traditional electric utility business, but is increasingly engaged in the competitive energy business as well. Therefore, both indexes have been selected for comparison purposes. FPL Group is included in all three indexes.

Corporate Governance Principles & Guidelines/Code of Ethics

FPL Group has had formal corporate governance standards in place since 1994. FPL Group has reviewed internally and with its board of directors the provisions of Sarbanes-Oxley, the rules of the Securities and Exchange Commission and the current corporate governance listing standards of the NYSE regarding corporate governance policies and processes, and FPL Group is in compliance with those provisions, rules and listing standards. The Governance & Nominating Committee is responsible for reviewing the Corporate Governance Principles & Guidelines and reporting and making recommendations to the FPL Group board of directors concerning corporate governance matters. FPL Group has adopted a Code of Ethics for Senior Executive and Financial Officers, which applies to FPL Group’s principal executive and financial officers, principal accounting officer and persons performing similar functions, as well as a Code of Business Conduct & Ethics applicable to all representatives of FPL Group, including directors, officers and employees. A copy of FPL Group’s Corporate Governance Principles & Guidelines, as well as copies of FPL Group’s Code of Ethics for Senior Executive and Financial Officers and Code of Business Conduct & Ethics, are available in the “Governance” section of FPL Group’s website at www.fplgroup.com/governance/contents/fplgroup_governance.shtml. You can also write to us for printed copies of these documents, without charge, at FPL Group, Inc., P.O. Box 14000, 700 Universe Boulevard, Juno Beach, Florida 33408-0420, Attention: Investor Relations.

Director Independence

The FPL Group board of directors has conducted a review regarding the independence of each of its members from management of FPL Group under the criteria legislated by the Sarbanes-Oxley Act, the corporate

193

governance independence standards in Section 303A of the NYSE Listed Company Manual (the “NYSE standards”) and FPL Group’s Corporate Governance Principles & Guidelines. The NYSE standards and FPL Group’s Corporate Governance Principles & Guidelines require that FPL Group have a majority of independent directors, require that the FPL Group board of directors make a determination as to independence, and set out certain independence criteria. The NYSE standards and FPL Group’s Corporate Governance Principles & Guidelines also require that each of the Compensation Committee, Governance & Nominating Committee and Audit Committee consist entirely of independent directors. The NYSE standards and Rule 10A-3 of the Securities Exchange Act of 1934 (the “Exchange Act”) include additional independence requirements for Audit Committee members.

As part of its independence assessment, the FPL Group board of directors considered whether any non-employee director or member of his or her immediate family has a material relationship with FPL Group that would impair the director’s independence. To assist it in making this determination, the Governance & Nominating Committee and the FPL Group board of directors have adopted categorical standards of independence that are included in FPL Group’s Corporate Governance Principles & Guidelines. Under those categorical standards, except in special circumstances, as determined by a majority of the independent members of the FPL Group board of directors, a director will be considered independent if FPL Group or any of its consolidated subsidiaries has made or received payments for property or services to or from any entity of which either (1) the director is an officer or employee or in which the director is a partner or has an ownership interest of 10% or more of the outstanding voting securities or other voting interests or (2) the director’s immediate family member is an executive officer, if such payments in the last fiscal year were less than the greater of $1 million or 2% of such other entity’s consolidated gross revenues for its last fiscal year and such property or services were provided or received in the ordinary course of business of each of the parties. In addition, except in special circumstances, as determined by a majority of the independent members of the FPL Group board of directors, a director will be considered independent if FPL Group or any of its consolidated subsidiaries has a borrowing relationship with a bank or other financial institution of which the director is an officer, employee or director, or the director’s immediate family member is an executive officer, if the total amount of indebtedness does not exceed 1% of the total assets of the financial institution for the last fiscal year.

For purposes of the foregoing discussion, an “immediate family member” is defined as a spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law and anyone (other than domestic employees) who shares the director’s home, but excluding any person who is no longer an immediate family member as a result of legal separation or divorce, or death or incapacitation.

Based on its review and the categorical standards, in February 2006 the FPL Group board of directors determined that Sherry S. Barrat, Robert M. Beall, II, J. Hyatt Brown, James L. Camaren, J. Brian Ferguson, Rudy E. Schupp, Michael H. Thaman, Hansel E. Tookes II and Paul R. Tregurtha, as well as retiring directors H. Jesse Arnelle and Frank G. Zarb, being all of the non-employee directors, are independent under the Sarbanes-Oxley Act, the NYSE standards and FPL Group’s Corporate Governance Principles & Guidelines.

Director Meetings and Attendance

The FPL Group board of directors met eight times in 2005, including six regular meetings and two special meetings. Each director attended at least 75% of the total number of board meetings and meetings of the committees on which he or she served. Absent circumstances that cause a director to be unable to attend the FPL Group board of directors meeting held in conjunction with the annual shareholders’ meeting, board members are required to attend the annual shareholders’ meeting. All of the eleven directors then in office attended the 2005 annual meeting of shareholders. The FPL Group board of directors and its committees meet on a regular schedule and also hold special meetings from time to time as deemed necessary and appropriate.

Executive Sessions of Non-Management Directors

Executive sessions of non-management directors are provided for in the agenda for each regularly-scheduled board meeting. The sessions are scheduled and chaired by a Presiding Director, who is currently Robert M. Beall,

194

II, the Chair of the Audit Committee. At the 2006 annual shareholders’ meeting, the Presiding Director position will rotate to Sherry S. Barrat, the Chair of the Compensation Committee, and thereafter will rotate annually among the non-management Chairs of the standing committees of the FPL Group board of directors, in alphabetical committee order; provided that no member of the board will serve two consecutive years as Presiding Director. See “—Post-Merger Governance and Management—Other Board of Directors Matters” beginning on page 147 for information regarding the selection of the combined company’s presiding director following completion of the merger.

Committees

The standing committees of the FPL Group board of directors are the Audit Committee, the Compensation Committee, the Governance & Nominating Committee and the Finance & Investment Committee. The membership during 2005 and function of these committees is described below. Each of the committees operates under a charter approved by the FPL Group board of directors. The charter of each of the Audit Committee, the Compensation Committee and the Governance & Nominating Committee complies with the NYSE corporate governance requirements (there are no NYSE requirements for the Finance & Investment Committee).

Consideration of Director Nominees

Shareholder Nominees

The policy of FPL Group’s Governance & Nominating Committee is to consider properly submitted shareholder nominations of candidates for membership on the FPL Group board of directors. See “Identifying and Evaluating Nominees for Directors.” In evaluating such nominations, the Governance & Nominating Committee seeks to achieve a balance of knowledge, experience and capability on the FPL Group board of directors and to address the membership criteria set forth below under “Director Qualifications.” Any shareholder nominations proposed for consideration by the Governance & Nominating Committee should include the nominee’s name and qualifications for board membership and should be addressed to: Corporate Secretary, FPL Group, Inc., P.O. Box 14000, 700 Universe Boulevard, Juno Beach, Florida 33408-0420.

There are separate requirements under regulations of the SEC and under FPL Group’s bylaws relating to shareholder nominations of persons for election to the FPL Group board of directors at a meeting of shareholders. See “Date For Submission of Shareholder Proposals — FPL Group” beginning on page 215, and “Comparison of Stockholders’ Rights — Nomination of Directors for Election” beginning on page 217.

Director Qualifications

FPL Group’s Corporate Governance Principles & Guidelines contain board membership criteria that are considered by the Governance & Nominating Committee in recommending non-employee nominees for a position on the FPL Group board of directors. Under these criteria, members of the FPL Group board of directors should have demonstrated character and integrity; an inquiring mind; experience at a strategy and/or policy setting level, or high-level managerial experience in a relatively complex business, government or other organization, or have other similar and relevant experience in dealing with complex problems; an ability to work effectively with others; sufficient time to devote to the affairs of FPL Group; and an ability to represent the balanced interests of the FPL Group shareholders as a whole, rather than special constituencies. Their service on other boards of public companies should be limited to a number that permits them, given their individual circumstances, to perform responsibly all director duties, and no Company director may serve simultaneously as a director of more than six public companies. Additional criteria include whether an individual assists in

197

achieving a mix of directors that represents a diversity of background and experience, including age, gender, race and specialized experience; whether an individual is nearing or has reached retirement age; the individual’s independence as described in applicable listing standards, legislation and regulations; whether the individual would be considered an “audit committee financial expert” or “financially literate” as described in applicable listing standards, legislation, regulations or Audit Committee guidelines; the extent of the individual’s business experience, technical expertise, or specialized skills or experience; and whether the individual, by virtue of particular experience relevant to FPL Group’s current or future business, will add specific value as a board member. No person will be considered for board membership who is an employee or director of a business in significant competition with FPL Group or of a major or potentially major customer, supplier, contractor, counselor or consultant of FPL Group, or an executive officer of a business where a Company employee-director serves on such other business’ board. No person who shall have attained the age of 72 years by the date of election shall be eligible for election as a director.

Identifying and Evaluating Nominees for Directors

The Governance & Nominating Committee utilizes a variety of methods for identifying and evaluating nominees for director. The committee periodically assesses the appropriate size of the FPL Group board of directors, and whether any vacancies on the board are expected due to retirement or otherwise. In the event that vacancies are anticipated, or otherwise arise, the committee considers various potential candidates for director if deemed appropriate. Candidates may come to the attention of the committee through current board members, professional search firms, shareholders or other persons. These candidates are evaluated at regular or special meetings of the committee, and may be considered at any point during the year. As described above, the committee considers properly submitted shareholder nominations for candidates for the FPL Group board of directors. Following verification of the shareholder status of persons proposing candidates, recommendations are aggregated and considered by the committee at a regularly scheduled meeting, which is generally the first or second meeting prior to the issuance of the proxy statement for FPL Group’s annual meeting. If any materials are provided by a shareholder in connection with the nomination of a director candidate, such materials are forwarded to the committee. The committee also reviews materials provided by professional search firms or other parties. In evaluating such nominations, the committee seeks to achieve a balance of knowledge, experience and capability on the FPL Group board of directors. See also “Date for Submission of Shareholder Proposals—FPL Group” on page 215 and “Comparison of Stockholders’ Rights—Nomination of Directors for Election” beginning on page 217.

J. Brian Ferguson, who was appointed to the FPL Group board of directors in July 2005, is a nominee for election to the board this year who has not previously been elected by the shareholders. A third-party search firm, which was retained to help identify and evaluate possible candidates, identified Mr. Ferguson as a possible candidate. The Governance & Nominating Committee reviewed a number of candidates submitted for consideration utilizing the criteria discussed under “Director Qualifications.” Several members of the Committee interviewed Mr. Ferguson, and Mr. Arnelle described to the other Governance & Nominating Committee members his experience with Mr. Ferguson during Mr. Arnelle’s service on the board of directors of Eastman Chemical Company, of which Mr. Ferguson is Chairman and CEO. Following its evaluation, the Governance & Nominating Committee recommended Mr. Ferguson for election to the FPL Group board of directors.

Represents, for all FPL Group directors other that Messrs. Ferguson, Schupp and Tookes, 2,000 shares valued at $39.82 per share, the closing price of FPL Group common stock on the date of grant, as adjusted for the March 15, 2005 stock split, and for Messrs. Ferguson, Schupp and Tookes, 400 shares valued at $43.12 per share, the closing price of FPL Group common stock on the date of grant. Shares generally may not be transferred until such time as the director ceases to be a member of the FPL Group board.

(2)

The amount listed includes the incremental cost to FPL Group for certain FPL Group directors’ spouses’ attendance at the FPL Group board’s offsite meeting and strategic planning retreat, plus, for all FPL Group directors, the premiums paid by FPL Group for travel and accident insurance covering non-employee directors for travel on company business.

(3)	Mr. Malek retired as a FPL Group director at the 2005 Annual Meeting on May 20, 2005.

Pursuant to FPL Group’s Corporate Governance Principles & Guidelines, to more closely align the interests of FPL Group directors and shareholders, FPL Group directors are encouraged to own a significant equity interest in FPL Group within a reasonable time after initial election to the FPL Group board of directors. An investment of three times the annual cash retainer within three years is the guideline amount. All independent FPL Group directors currently meet these stock ownership guidelines. See “Common Stock Ownership of Certain Beneficial Owners and FPL Group Management” beginning on page 192.

FPL Group directors who are salaried employees of FPL Group or any of its subsidiaries do not receive any additional compensation for serving as a director or committee member. Effective January 1, 2006, non-employee directors of FPL Group receive an annual retainer of $32,000 plus a number of shares of FPL Group common stock determined by dividing $100,000 by the closing price of the FPL Group common stock on the grant date, rounded up to the nearest ten shares. The grant date for the annual retainers paid for 2006 was February 16, 2006, at which time the non-employee directors of FPL Group were each granted 2,400 shares of FPL Group common stock. These shares are generally not transferable until the director ceases to be a member of the board of directors. Non-employee FPL Group committee chairpersons receive an additional annual retainer of $10,000 for the Audit Committee and $5,000 for the other committees. A fee of $1,500 is paid to non-employee directors for each FPL Group board of directors or committee meeting attended. Newly-elected non-employee directors are awarded 400 shares of FPL Group common stock when they join the FPL Group board of directors. These shares are not transferable until the director ceases to be a member of the board and are subject to forfeiture if the director ceases to be a director within five years of his initial election to the board for any reason other than death, disability or attainment of the board’s mandatory retirement age. FPL Group directors may defer all or a portion of their cash and equity compensation in FPL Group’s Deferred Compensation Plan and may participate in FPL Group’s matching gift program, which matches gifts to educational institutions to a

199

maximum of $10,000 per donor. Travel expenses to attend FPL Group board of directors or committee meetings or while on FPL Group board of directors business are reimbursed.

Effective November 1, 1996, FPL Group’s Non-Employee Director Retirement Plan was terminated. Retirement benefits of non-employee directors in office in 1996 and not retiring at or prior to the 1997 annual shareholders’ meeting were converted to share units of FPL Group common stock. The number of share units was fixed on the conversion date, and each participating director is credited quarterly with an amount equal to the dividends that would have been paid on such number of share units, plus interest thereon. Each participating director will be entitled to payment of the then current value of these share units, plus cash dividends and interest, upon ending service as a FPL Group board member. Messrs. Arnelle, Beall and Brown participate in this program. Upon his retirement from the FPL Group board of directors in May 2005, Frederic V. Malek received a life and 120 months certain annuity valued at approximately $465,000 under this program. Mr. Arnelle, whose benefits under this program will be determined upon his retirement from the board as of the date of the Annual Meeting, would have been entitled to receive approximately $556,178 under the program, based on an assumed retirement date of June 30, 2006 and the $41.38 closing share price of FPL Group common stock on such date.

FPL Group Audit Committee Report

The Audit Committee submits the following report for 2005:

The Audit Committee of the board of directors consists of five independent directors. The responsibilities of the Committee are set forth in its written charter, which has been adopted by the board of directors. A copy of that charter, which was amended in July 2005, is included as Annex I to this joint proxy statement/prospectus.

In accordance with the Charter, the Committee assists the FPL Group board of directors in fulfilling its responsibility for oversight of the quality and integrity of the accounting, auditing and financial reporting practices of FPL Group. During 2005, the Committee met nine times, including four meetings where the Committee discussed the interim financial information contained in each quarterly earnings announcement with the chief accounting officer and independent auditors prior to public release.

In discharging its oversight responsibility as to the audit process, the Audit Committee obtained from the independent auditors a formal written statement describing all relationships between the auditors and FPL Group that might bear on the auditors’ independence consistent with Independence Standards Board Standard No. 1, “Independence Discussions with Audit Committees,” discussed with the auditors any relationships that may impact their objectivity and independence and satisfied itself as to the auditors’ independence. The Committee also discussed with management, the internal auditors and the independent auditors the quality and adequacy of FPL Group’s internal controls and the internal audit function’s organization, responsibilities, resources and staffing. The Committee reviewed with both the independent and the internal auditors their audit plans, audit scope, and identification of audit risks.

The Committee discussed and reviewed with the independent auditors all communications required by generally accepted auditing standards, including those described in Statement on Auditing Standards No. 61, as amended, “Communication with Audit Committees” and discussed and reviewed the results of the independent auditors’ examination of the financial statements. The Committee also discussed the results of the internal audit examinations.

The Committee reviewed and discussed the audited financial statements of FPL Group for the year ended December 31, 2005, with management and the independent auditors. Management has the responsibility for the preparation of FPL Group’s financial statements, and the independent auditors have the responsibility for the examination of those statements.

Based on the above-mentioned review and discussions with management and the independent auditors, the Committee recommended to the FPL Group board of directors that FPL Group’s audited financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2005, for filing with the Securities and Exchange Commission.

200

In addition, and in accordance with the Charter, the Committee reviewed and discussed with management and the independent auditors management’s internal control report, management’s assessment of the internal control structure and procedures of FPL Group for financial reporting, and the independent auditor’s attestation of management’s assessment, all as required to be included in FPL Group’s Annual Report on Form 10-K for the year ended December 31, 2005.

As specified in the Charter, it is not the duty of this Committee to plan or conduct audits or to determine that FPL Group’s financial statements are complete and accurate and in accordance with generally accepted accounting principles. These are the responsibilities of FPL Group’s management and independent auditors. In discharging our duties as a Committee, we have relied on (i) management’s representations to us that the financial statements prepared by management have been prepared with integrity and objectivity and in conformity with generally accepted accounting principles, and (ii) the report of the independent auditors with respect to such financial statements.

Compensation Committee Report

The Compensation Committee submits the following report for 2005:

Overview and Philosophy

FPL Group’s executive compensation program is designed to align compensation with FPL Group’s business strategy, its goals and values, and the return to its shareholders. The program is also designed to provide a competitive compensation package, both in terms of its components and overall, that will attract, motivate, and retain key executives critical to the long-term success of FPL Group. The Committee uses three primary compensation elements to achieve these goals: base salary, annual incentive compensation and long-term incentive compensation, each of which is discussed in detail below. Generally, compensation is weighted towards performance-based incentive compensation, and the more senior the position, the greater the portion of compensation that is based on performance.

The Committee determines an executive’s competitive total level of compensation based on information drawn from a variety of sources, including utility and general industry surveys, proxy statements, and independent compensation consultants. FPL Group’s 2005 “comparator group” consists of thirteen electric utilities (nine of which are included in the Dow Jones Utilities Index and seven of which are included in the Standard & Poor’s 500 Electric Utilities Index) and twenty-one general industry companies. Electric utility industry trends (i.e., deregulation and increasing competition) and the need to recruit from outside the industry are the principal reasons for including companies other than electric utilities in the comparator group. Compensation during 2005 for Lewis Hay, III also was required to comply with the terms of his Employment Agreement dated February 25, 2005, as amended, which is described under “Employment Agreement with CEO,” below. The Committee has reviewed the components of the CEO’s and each named executive officers’ compensation, including base salary, annual incentive compensation, long-term incentive compensation grants and payouts, costs of perquisites and other personal benefits, and annual accruals under FPL Group’s supplemental executive retirement plan. Tally sheets setting forth all of the above components of pay were prepared by a third-party executive compensation expert and reviewed by the Committee.

201

Compensation Elements

1. Base Salary

Base salaries are set by the Committee and are designed to be competitive with the comparator group companies described above. Generally, the Committee targets salary levels between the second and third quartiles of the comparator group, adjusted to reflect the individual’s job experience and responsibilities. Increases in base salaries are based on the comparator group’s practices, FPL Group’s performance, and the individual’s performance. The corporate performance assessment used to determine adjustments to executive officers’ base salaries is based on the same performance assessment used to determine annual incentive compensation, as discussed below in regard to the chief executive officer’s compensation. Base salaries are reviewed for adjustment annually.

2. Annual Incentive Awards

Annual incentive compensation is based on the attainment of net income goals for FPL Group, which are established by the Committee at the beginning of the year, and as reported in the annual audited financial statements of FPL Group, as determined in accordance with generally accepted accounting principles, adjusted to exclude the impact on net income of any changes in accounting principles, any changes in the mark-to-market value of non-qualifying hedges, extraordinary items, non-recurring charges or gains, discontinued operations, regulatory and/or legislative changes, labor union disruptions and acts of God such as hurricanes (“adjusted net income”). The amounts earned on the basis of this performance measure are subject to reduction based on the degree of achievement of other corporate performance measures (and in the case of Florida Power & Light, business unit performance measures), and at the discretion of the Committee. These other corporate performance measures, which for 2005 consisted of the financial, operating and growth indicators discussed below in regard to the chief executive officer’s compensation, and business unit performance measures were also established by the Committee at the beginning of the year. For 2005, the adjusted net income goal was met, and the average level of achievement of the other performance measures exceeded the targets. However, the amounts paid out for 2005 were less than the amounts that could have been paid based on maximum achievement of all targets.

3. Long-Term Incentive Awards

Since 2002, long-term incentive compensation has been comprised of performance share awards, restricted stock awards and stock option awards. Performance share awards are based primarily on the average level of achievement under the annual incentive plans over a specified period, which since 2003 has been three years. Targeted awards for performance share awards, in the form of shares granted under FPL Group’s Amended and Restated Long Term Incentive Plan, are made at the beginning of the period. Since one of the goals of the performance share program is to link directly the financial interests of the FPL Group shareholders and senior management, performance share award payouts (except for cash for the payment of incomes taxes) are made in shares of FPL Group common stock which the recipient is expected to retain in accordance with FPL Group’s policies on stock ownership and retention discussed below. Long-term incentive compensation also includes stock options and restricted stock in amounts intended to ensure that FPL Group’s total executive compensation program is competitive, in terms of both composition and amount, with the compensation programs of other companies with which FPL Group competes for executive talent. Restricted stock awards for the CEO and other officers named in FPL Group’s Summary Compensation Table include a performance-based component, as vesting requires achievement of adjusted net income targets established by the Committee. Beginning in 2004, for most officers, FPL Group reduced the use of stock options and increased the use of restricted stock awards as elements of executive incentive compensation.

Stock Ownership and Retention Policies

FPL Group’s policy on stock ownership, adopted by the Governance & Nominating Committee in May 2002, requires officers of FPL Group and its subsidiaries to have an ownership stake in FPL Group to more closely align the interests of officers and shareholders. To maintain this alignment of interests, the Compensation Committee adopted a share retention policy in March 2003, and revised that policy in December 2004, for all officers of FPL Group and its subsidiaries.

202

Under the stock ownership policy, officers are expected, ordinarily within three years after election to office, to own FPL Group common stock with a value of a multiple of their base salary (as adjusted from time to time) as follows:


Chief Executive Officer		three times base salary
Senior Executive Officers		two times base salary
Other Officers		one times base salary

Shares of FPL Group common stock or share units held in FPL Group’s employee benefit plans and deferred compensation plan are credited toward meeting these guidelines. Under a separate share retention policy, FPL Group expects all senior officers (as designated by the chief executive officer and including the chief executive officer) to maintain a minimum retention ratio (number of shares and share units owned divided by the sum of shares acquired after March 24, 2003 through long-term incentive plan awards plus all other shares, net of taxes) of at least two-thirds until termination of employment, retirement or age 60. Other officers are expected to maintain a minimum retention ratio of at least one-third. The minimum retention guidelines may be modified or reduced to address the special needs of a particular officer.

Compensation of the Chief Executive Officer

The Committee annually approves the compensation of Mr. Hay, FPL Group’s chief executive officer, based on their assessment of his leadership performance and effectiveness, including attainment of short-term and long-term financial and strategic objectives and other significant accomplishments. The Committee’s decisions concerning 2005 total compensation (and specific elements of compensation) paid to Mr. Hay were also made after consultation with an executive compensation expert.

For 2005, Mr. Hay was paid $1,000,000 in base salary, $1,740,000 in annual incentive compensation, and $7,060,823 in long-term incentive compensation (consisting of 169,081 shares of FPL Group common stock for the payout of performance share awards, which he elected to defer). In addition, Mr. Hay was awarded options in 2005 for 100,000 shares of FPL Group common stock and 60,000 shares of restricted FPL Group common stock, all of which vest one-third each year for three years. The base salary reflects the Committee’s assessment of Mr. Hay’s overall performance and an analysis of the salaries of the chief executive officers in the comparator group.

Mr. Hay’s annual incentive compensation for 2005 was based on the achievement of FPL Group’s adjusted net income goals, and the following performance measures for Florida Power & Light (weighted 75%) and FPL Energy LLC (weighted 25%). For Florida Power & Light, the incentive performance measures were financial indicators (weighted 40%) and operating indicators (weighted 60%). The financial indicators were operations and maintenance costs, capital expenditure levels, adjusted net income, and regulatory return on equity. The operating indicators were service reliability as measured by the frequency and duration of service interruptions and service unavailability; system reliability as measured by availability factors for the fossil power plants and an industry index for the nuclear power plants; employee safety; number of significant environmental violations; customer satisfaction survey results; and a milestone indicator related to certain significant Florida Power & Light regulatory matters. For FPL Energy, the incentive performance measures were a financial indicator (weighted 45%), operating indicators (weighted 30%) and growth indicators (weighted 25%). The financial indicator was FPL Energy adjusted net income. The operating indicators were employee safety; number of significant environmental violations; project-level and corporate budget targets; equivalent forced outage rate; and level of hedged margin. The growth indicators included targets for new development or acquisition, asset optimization and trading.

Mr. Hay’s long-term compensation for 2005 consisted of payouts under a four-year performance share award granted in 2002 and a three-year performance share award granted in 2003. The performance share award

203

payout was based on an average level of achievement of better than 100% of target with respect to the annual incentive plan for the years ended December 31, 2002, December 31, 2003, December 31, 2004, and December 31, 2005. As in 2005, the performance measures for 2002, 2003 and 2004 were based on predefined financial, operational, and strategic objectives.

In February 2005, FPL Group entered into an employment agreement with Mr. Hay, which was amended December 15, 2005; this agreement and amendment are described under “Employment Agreement with CEO” herein. In connection with its review and approval of the agreement and of the amendment, the Committee consulted with its outside legal counsel and with an outside compensation consultant.

Internal Revenue Code Section 162(m)

Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to public companies for compensation exceeding $1 million paid to the chief executive officer or any of the four other highest-paid executive officers unless certain specified criteria are satisfied. Interpretations of and changes in tax laws and regulations, as well as other factors beyond the Committee’s control, can affect deductibility of compensation. For these and other reasons, it may not be possible to keep a given person’s compensation under the Section 162(m) limit or to qualify all compensation for deductibility in a particular year. Although maintaining the deductibility of compensation remains an important goal of the Committee, the Committee has approved elements of compensation for certain officers, including Mr. Hay, that are not fully deductible, and reserves the right to do so in the future in appropriate circumstances. The Committee will continue to monitor developments, assess alternatives for preserving, and take actions to preserve, the deductibility of compensation payments and benefits to the extent reasonably practicable, consistent with what the Committee considers to be a sound compensation program, which is competitive and enables us to attract and retain a highly-capable and dedicated management team in furtherance of the best interests of FPL Group and its shareholders.

(a)

This column includes, for 2005 and 2004, the aggregate incremental cost to FPL Group of providing personal benefits to the named executive officers, earnings on long-term incentive plan compensation paid or payable during that year but deferred at the election of the individual, and amounts reimbursed for the payment of taxes. The personal benefits reported for 2005 in this column that represent at least 25% of the total dollar value of an individual’s personal benefits in 2005 are as follows: costs to FPL Group for use of a leased automobile for Mr. Robo $16,837, Mr. Olivera $15,267, Mr. Dewhurst $18,928, and Mr. Stall $21,470; the cost of premiums for personal and dependent medical insurance coverage for Mr. Stall $17,856; the cost of financial and legal planning reimbursement for Mr. Robo $10,000 and Mr. Olivera $10,000; the cost of club membership dues and fees for Mr. Hay $59,535; and payment of legal bills of $56,363 on behalf of Mr. Hay in conjunction with the negotiation of his employment agreement. The personal benefits reported for 2004 in this column that represent at least 25% of the total dollar value of an individual’s personal benefits in 2004 are as follows: costs to FPL Group for use of a leased automobile for Mr. Robo $16,220, Mr. Olivera $18,693, Mr. Dewhurst $20,385 and Mr. Stall $18,684; the cost of premiums for personal and dependent medical insurance coverage for Mr. Hay $30,540 and for Mr. Stall $16,688, and the cost of financial and legal planning reimbursement for Mr. Robo $10,000 and Mr. Olivera $10,000. This column also includes, for 2005 and 2004, respectively, amounts reimbursed for the payment of taxes on personal benefits as follows: Mr. Hay $87,112 and $18,913, Mr. Robo $13,607 and $12,490, Mr. Olivera $13,875 and $21,199, Mr. Dewhurst $9,580 and $9,043, and Mr. Stall $12,926 and $13,016. The incremental cost to FPL Group of providing personal benefits to the named executive officers in 2003 did not exceed $50,000 for any individual and therefore, consistent with SEC rules, is excluded from the table; the amounts included in this column for 2003 are amounts reimbursed for the payment of taxes on personal benefits and earnings on long-term incentive plan compensation payable during the particular year but deferred at the election of the individual.

For 2003, 2004 and 2005, payouts of vested performance share awards were made in a combination of cash (for required income tax withholding) and shares of FPL Group common stock, valued at the closing price of the FPL Group common stock on the date such payouts were approved by the Compensation Committee. During 2005, two performance share awards, one made in 2002 covering a four-year performance period, and one made in 2003 covering a three-year performance period, vested and were paid. Although generally only one long-term performance period ends each year, in 2003 the Compensation Committee determined that a three-year performance period was more appropriate, which resulted in this one-time overlap. Mr. Hay deferred his 2003, 2004 and 2005 performance share award payouts, Mr. Dewhurst deferred his 2003 performance share award payout, and Mr. Stall deferred his 2003 and 2004 performance share award payouts under FPL Group’s Deferred Compensation Plan. For 2004, payouts of vested shareholder value awards were made in cash, based on the closing price of FPL Group common stock on the date payouts were approved.

(d)

Represents employer matching contributions to thrift plans, supplemental matching contributions under the supplemental executive retirement plan, as amended (SERP), and employer contributions for life insurance. For 2005, employer matching contributions to thrift plans equaled $9,975 for each of the named officers, and supplemental matching contributions under the SERP were credited as follows: Mr. Hay $133,034, Mr. Robo $46,132, Mr. Olivera $44,303, Mr. Dewhurst $44,843, and Mr. Stall $15,003. For 2005, also represents employer contributions for life insurance as follows: Mr. Hay $22,289, Mr. Robo $7,935, Mr. Olivera $11,019, Mr. Dewhurst $249 and Mr. Stall $7,930.

(e)	Mr. Olivera served as senior vice president, power systems of Florida Power & Light from July 1999 to June 2003 and was appointed president of Florida Power & Light in June 2003.

Long Term Incentive Plan Awards

In 2005, restricted stock awards under FPL Group’s Amended and Restated Incentive Plan (“LTIP”) were made to the executive officers named in the Summary Compensation Table as set forth above. In addition, performance share awards and non-qualified stock option awards under the LTIP were made to the executive officers named in the Summary Compensation Table as set forth in the following tables.

Performance Share Awards


			Estimated Future Payouts Under Non-Stock Price- Based Plans
Name	Number of Shares (#)	Performance Period Until Payout	Target (#)	Maximum (#)
Lewis Hay, III	58,808	1/1/05-12/31/07	58,808	94,092
James L. Robo	14,326	1/1/05-12/31/07	14,326	22,921
Armando J. Olivera	14,326	1/1/05-12/31/07	14,326	22,921
Moray P. Dewhurst	14,578	1/1/05-12/31/07	14,578	23,324
John A. Stall	11,302	1/1/05-12/31/07	11,302	18,083

The performance share awards in the preceding table are, under normal circumstances, payable at the end of the performance period indicated. The amount of the payout is determined by multiplying the participant’s target number of shares by his average level of attainment, expressed as a percentage, which may not exceed 160%, of his targeted awards under the Annual Incentive Plans for each of the years encompassed by the award period. A description of the 2005 Annual Incentive Plan performance indicators is included in the Compensation Committee Report, above. The performance share award payouts for the performance periods ending December 31, 2005 are included in the Summary Compensation Table above in the column entitled “LTIP Payouts.” During 2005, two performance share awards, one made in 2002 covering a four-year performance

206

period, and one made in 2003 covering a three-year performance period, vested and were paid. Although generally only one long-term performance period ends each year, in 2003 the Compensation Committee determined that a three-year performance period was more appropriate, which resulted in this one-time overlap.

Option Grants in Last Fiscal Year

John A. Stall	30,000	7	%	36.95	1/3/2015	189,000

(a)

Options granted are non-qualified stock options. All stock options vest and become exercisable at the rate of one-third per year and are fully exercisable after three years. All options were granted at an exercise price per share of 100% of the fair market value of FPL Group common stock on the date of grant.

(b)

The hypothetical values shown were calculated using the Black-Scholes option pricing model, based on the following assumptions. For all options, the volatility rate is equal to 20.00% and the dividend yield (representing the per-share annualized dividends as of the grant date divided by the annualized fair market value of the common stock) is equal to 3.68%. The risk-free interest rate is equal to 4.08%, based on the interest rate on a U.S. Treasury zero-coupon bond on the date of grant with a maturity corresponding to the estimated time until exercise of seven years. The values do not take into account risk factors such as non-transferability or risk of forfeiture.

The preceding table sets forth information concerning individual grants of common stock options during fiscal year 2005 to the executive officers named in the Summary Compensation Table. Such awards are also listed in the Summary Compensation Table above in the column entitled “Securities Underlying Options.”

The preceding table sets forth information, with respect to the named officers, concerning the exercise of stock options during the fiscal year and unexercised options held at the end of the fiscal year. The named officers did not exercise any stock options during 2005. All the exercisable and unexercisable options shown in the preceding table were granted in 2001, 2002, 2003, 2004 and 2005. At December 30, 2005, the fair market value of the underlying securities (based on the closing share price of FPL Group common stock reported on the New York Stock Exchange) was $41.56 per share, and exceeded the exercise price of all of the exercisable and unexercisable options.

Retirement Plans

FPL Group maintains a non-contributory defined benefit pension plan and a supplemental executive retirement plan (SERP). The FPL Group Employee Pension Plan and SERP were converted to a cash balance accrual formula effective April 1, 1997. However, participants in the SERP as of April 1, 1997 continue to accumulate benefits pursuant to the final average pay benefit formula in place prior to the cash balance change.

The following table shows the estimated annual benefits derived using the final average pay formula used to determine the pensions of participants in the SERP as of April 1, 1997. Only two executive officers named in the Summary Compensation Table, Messrs. Olivera and Stall, will have their benefits determined in this manner. The benefits shown are the amounts that would be payable in the form of a single life annuity to participants retiring in 2005 at age 65 after working the indicated years of service. Pursuant to the final average pay benefit formula, the benefits shown are offset by a fraction of expected Social Security benefits due to employer contributions for those benefits.

1,400,000		139,116		278,243		556,475		694,718		730,430

(a)

The maximum eligible average annual compensation shown in the table is based on 120% of the 2005 pensionable earnings (which includes annual salary and bonus as shown in the Summary Compensation Table) for Mr. Olivera. He is the most highly compensated named officer who was a SERP participant in 1997 and so was not impacted by the cash balance change.

The compensation covered by the plans includes Mr. Olivera’s 2005 annual salary and bonus and Mr. Stall’s 2005 annual salary, but no other amounts shown in the Summary Compensation Table. Beginning in 2006, covered compensation for Mr. Stall will include annual salary and annual incentive award. Messrs. Olivera and Stall had completed approximately 33 and 9 years of credited service respectively as of December 31, 2005.

Messrs. Hay, Robo and Dewhurst are the named executive officers covered solely by the cash balance formula in the plans. Benefits under the cash balance formula are based upon annual salary and awards under the annual incentive plan (which are included in the “Bonus” column of the Summary Compensation Table). Under the cash balance formula, credits are accumulated in an employee’s account and are determined as a percentage of the employee’s monthly covered earnings in accordance with the following formula:


Years of Service	Percent of Compensation
0-5	4.5	%
5 or more	6.0	%

208

Effective January 1, 2006, the cash balance accruals under the plans for Messrs. Robo and Dewhurst will be determined as a percentage of their respective monthly covered earnings in accordance with the following formula:


Years of Service	Percent of Compensation
0-5	9	%
5 or more	12	%

In addition, the employee’s account is credited quarterly with interest at an annual rate that is based upon the yield on one-year Treasury Constant Maturities. The interest crediting rate is subject to a 4% floor, which was the rate utilized in 2005. Benefits under the cash balance formula are not reduced for employer contributions to Social Security or other offset amounts.

The estimated age 65 annual retirement benefit payable under the plans, based upon total covered compensation from FPL Group and subsidiaries, which was included in their 2005 taxable income (expressed as a joint and 50% survivor benefit) is $432,087 for Mr. Hay, $594,975 for Mr. Robo, and $259,891 for Mr. Dewhurst. These estimates assumes that the individuals’ 2005 pensionable earnings increase annually (salary by 4% per year, and annual incentive awards equal to 151% of salary for Mr. Hay, 121% of salary for Mr. Robo, and 96% of salary for Mr. Dewhurst) until age 65 and a cash balance interest crediting rate of 4.0% for 2005 and 2006 and 5.0% thereafter. The estimated age 65 cash balance account was converted to an annuity based on a 4.46% discount rate and the Revenue Ruling 2001-62 Mortality Table.

A supplemental retirement plan for Mr. Hay provides a benefit equal to 65% of Mr. Hay’s highest average annual compensation (annual salary plus annual incentive award) for the three consecutive calendar year periods out of the four consecutive calendar year period ending with the calendar year in which he retires (final average pay). This supplemental benefit will be reduced by the actuarial equivalent of the benefits to which he is entitled under the pension plan and the SERP. If Mr. Hay terminates his employment prior to age 65, the benefit will be reduced on a pro rata basis if he fails to complete at least fifteen years of service with FPL Group or its subsidiaries, and it will be further reduced on an actuarial basis as a result of its early distribution. The plan provides a minimum annual benefit, in the form of a joint and 50% survivor annuity (equal to 50% of final average pay) payable to Mr. Hay and his surviving spouse upon his termination of employment with FPL Group and its subsidiaries. If Mr. Hay’s termination of employment occurs prior to his normal retirement age (age 65), this minimum benefit will be reduced on an actuarial basis. Under the supplemental plan, Mr. Hay’s estimated age 65 annual retirement benefit (expressed as a joint and 50% survivor benefit, and calculated based on the same covered compensation and the same assumed increases in pensionable earnings as described in the preceding paragraph) would constitute an increase of approximately $2,503,747 over the estimate described above for the cash balance formula pension plan and SERP benefits, for a total estimated age 65 annual benefit of $2,935,834.

FPL Group sponsors a split-dollar life insurance plan for certain of its officers, including the executive officers named in the Summary Compensation Table with the exception of Mr. Dewhurst. Benefits under the split-dollar plan are provided by universal life insurance policies purchased by FPL Group. If the officer dies prior to retirement (defined to include age plus years of service), or for Mr. Olivera during employment or after retirement but prior to age 65, the officer’s beneficiaries generally receive two and one-half times the officer’s annual salary at the time of death. If the officer dies after retirement, or for Mr. Olivera on or after age 65, but before termination of his split-dollar agreement, the officer’s beneficiaries receive a percentage of the officer’s final annual salary (100% to 180% depending upon age at time of death for Mr. Olivera and 50% for the other named executive officers who participate in the plan). Upon termination of the agreement, which occurs after the later of 10 years from entering into the agreement, age 65, or a termination of employment which qualifies as retirement, the life insurance policies will be assigned to the officer or his beneficiary. For 2005, income was imputed to each participating executive officer for the value of the term coverage at a rate provided in the Internal Revenue Service’s Notice 2001-10 (Table 2001 Rates).

Employment Agreements

Employment Agreement with CEO

In February 2005 FPL Group entered into an employment agreement with Mr. Hay. The agreement provides for Mr. Hay to be employed as the chief executive officer and president of FPL Group (referred to in the employment agreement as the “Corporation”) and to serve as a director and chairman of FPL Group’s board of directors for an initial term of three years beginning January 1, 2005. Each January 1 beginning in 2006 the term of employment will be extended an additional year unless either party gives a notice of non-extension no later than 90 days prior thereto. If FPL Group terminates Mr. Hay’s employment without “cause,” or if Mr. Hay terminates his employment for “good reason” (each as defined in the agreement) he is entitled to receive a pro rata portion of his annual incentive bonus for the year in which termination occurs (calculated at the higher of target or the average of the bonus received for the prior two years); two times his then current base salary; two times the higher of (i) his average annual incentive bonus for the prior two years or (ii) his then current target annual incentive bonus; a pro rata portion of each outstanding and unvested performance share grant then in progress under FPL Group’s Long Term Incentive Plan (calculated as if target performance for the year of termination is achieved); continued vesting in all outstanding and unvested restricted stock awards and stock options for a period of two years following the date of termination; the cash value of two additional years of service credit under all applicable pension, 401(k), and supplemental retirement plans; and continued participation in FPL Group’s medical, dental, hospitalization, disability and group life insurance plans for up to two years. The agreement also provides for certain payments to be made upon termination because of death or disability or upon retirement. The agreement does not establish Mr. Hay’s compensation; however, reduction of his then current base salary, target annual incentive bonus, target long term incentive compensation or aggregate employee benefits (with certain exceptions) constitutes “good reason”.

Effective December 18, 2005, Mr. Hay’s employment agreement was amended to provide that “Corporation”, for purposes of the employment agreement, will be defined as FPL Group, or the ultimate parent entity of FPL Group, in the event that any entity directly or through one or more subsidiaries holds 50% or more of the outstanding voting stock of FPL Group.

In the event that Mr. Hay’s executive retention employment agreement with FPL Group (described below) becomes effective and his employment is terminated under the circumstances specified therein, he will be entitled to the compensation and benefits provided under that agreement in lieu of any entitlements payable or provided to him under the February 2005 agreement.

Executive Retention Employment Agreements

Each of the individuals named in the Summary Compensation Table is a party to an executive retention employment agreement with FPL Group. Each agreement will not become effective until the occurrence of a potential change of control or a change of control, each as defined in the agreement.

Change of control is defined in the agreements as (i) the acquisition by any individual, entity, or group of 20% or more of either FPL Group’s common stock or the combined voting power of FPL Group other than directly from FPL Group or pursuant to a merger or other business combination which does not itself constitute a change of control, (ii) the incumbent directors of FPL Group ceasing, for any reason, to constitute a majority of the FPL Group board of directors, unless each director who was not an incumbent director was elected, or nominated for election, by a majority of the incumbent directors and directors subsequently so elected or appointed (excluding those elected as a result of an actual or threatened election contest or other solicitation of proxies), (iii) the shareholders approve or, if determined by the FPL Group board of directors, there is consummated a merger, sale of assets, reorganization or other business combination of FPL Group or any subsidiary with respect to which (x) the voting securities of FPL Group outstanding immediately prior to the transaction do not, immediately following the transaction, represent more than 60% of the common stock and the voting power of all voting securities of the resulting ultimate parent entity or (y) members of the FPL Group

210

board of directors constitute less than a majority of the members of the board of directors of the resulting ultimate parent entity, or (iv) the shareholders approve the liquidation or dissolution of FPL Group. A potential change of control is defined as (i) announcement of an intention to take or consider taking actions which, if consummated or approved by shareholders, would constitute a change of control, or (ii) the acquisition by any individual, entity, or group of 15% or more of either the FPL Group common stock or the combined voting power of FPL Group other than directly from FPL Group or pursuant to a merger or other business combination which does not itself constitute a change of control.

Once effective, each named executive officer’s agreement provides that he shall be employed by FPL Group for a period of three years (two years, in the case of Mr. Stall) in a position at least commensurate with his position with FPL Group in the ninety-day period immediately preceding the effective date of the agreement. During this two or three year employment period, each named executive officer shall be (i) paid an annual base salary at least equal to his annual base as in effect on the effective date, with annual increases consistent with those awarded to other peer officers of FPL Group, but not less than the increases in the consumer price index; (ii) paid an annual bonus (expressed as a percentage of his annual base salary) consistent with those of peer executives of FPL Group, but at least equal to the higher of (x) his targeted annual bonus for the then current fiscal year divided by his then current annual base salary or (y) the average percentage of his annual base salary (as in effect for the applicable years) that was paid or payable as an annual bonus for each of the three fiscal years preceding the fiscal year in which the effective date occurs (or, if higher, for each of the three fiscal years immediately preceding the fiscal year in which a change of control occurs, if a change of control occurs after the effective date); (iii) given the opportunity to earn long-term incentive compensation no less favorable than such opportunities given to him at any time during the 90 days preceding the effective date or, if more favorable, those provided at any time after the effective date to peer officers of FPL Group; and (iv) entitled to participate in savings, retirement and other employee benefit plans providing benefits no less favorable than those provided to him at any time during the 90 days preceding the effective date or, if more favorable, those provided at any time after the effective date to peer officers of FPL Group.

In the event of a change of control, each agreement provides that (unless the terms of the award agreement expressly provide otherwise) (i) 50% of a named executive officer’s outstanding performance stock-based awards (for example, performance share awards) shall be vested and earned at an achievement level equal to the higher of (x) the targeted level of performance of each such award or (y) the average level (expressed as a percentage of target) of achievement in respect of similar awards maturing over the three fiscal years immediately prior to the year in which the change of control occurred; (ii) all other outstanding performance stock-based awards granted to the named executive officer shall be fully vested and earned; (iii) all options and other exercisable rights granted to the named executive officer shall become exercisable and vested; and (iv) the restrictions, deferral limitations and forfeiture conditions applicable to all outstanding awards granted to the named executive officer under an incentive compensation plan shall lapse and such awards shall be deemed fully vested.

A named executive officer will receive the remaining 50% of the outstanding performance stock-based awards (calculated in the same manner as described above and unless the terms of the award agreement expressly provide otherwise) on the first anniversary of the change of control if he has remained employed by FPL Group or an affiliate through such date or upon an earlier termination of employment by FPL Group (except for death, disability or cause) or by the named executive officer for “good reason” (as defined in the agreement). Upon such a termination of employment following a change of control and during the employment period, the named executive officer is entitled to, among other things, a lump sum severance payment equal to three times (two times, in the case of Mr. Stall) the sum of his annual base salary plus his annual bonus; a payment in respect of three years (two years, in the case of Mr. Stall) of foregone supplemental retirement benefits; continued coverage under all employee benefit plans, and certain other benefits and perquisites, for three years (two years, in the case of Mr. Stall); and a full gross-up in respect of any excise tax incurred as a result of the benefits received pursuant to the agreement. Such amounts and benefits would also be provided if such a termination of a named executive officer occurs following a potential change of control and prior to an actual change of control, and during the employment period, except that 100% of the outstanding performance stock-based awards (calculated as

211

described above) would be vested and earned. In addition, each named executive officer will also receive a pro rata portion (based upon deemed employment until the end of the two or three year employment period) of each long-term incentive compensation award granted to him on or after the date of the change of control. See “—Additional Interests of FPL Group’s Directors and Executive Officers in the Merger—Executive Retention Employment Agreements” beginning on page 113 for additional details about the agreements.

Amendments (effective December 18, 2005) were made to the executive retention employment agreements with the named executive officers. See “—Additional Interests of FPL Group’s Directors and Executive Officers in the Merger—Executive Retention Employment Agreements” beginning on page 113 for a description of such amendments, which relate specifically to the merger.

FPL GROUP PROPOSAL 3: RATIFICATION OF APPOINTMENT OF DELOITTE & TOUCHE AS FPL GROUP’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2006

Vote Required; Recommendation of the FPL Group Board of Directors

Approval of the proposal to ratify Deloitte & Touche LLP as FPL Group’s independent registered public accounting firm for the year 2006 requires the affirmative vote of a majority of the total number of shares represented at the meeting and entitled to vote, assuming a quorum is present.

Abstentions have the same effect as a vote against the ratification of Deloitte & Touche LLP as FPL Group’s independent registered public accounting firm for 2006 and broker non-votes have no legal effect. See “Information About the Annual Meetings and Voting” beginning on page 36.

THE FPL GROUP BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT FPL GROUP SHAREHOLDERS VOTE FOR RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS FPL GROUP’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2006.

General

It has appointed Deloitte & Touche LLP as the independent registered public accounting firm to audit the accounts of FPL Group and its subsidiaries, as well as to attest to management’s assessment of internal control over financial reporting and audit the effectiveness of FPL Group’s internal controls over financial reporting, for the fiscal year ending December 31, 2006. If the shareholders do not ratify the appointment, it will be reconsidered by the Audit Committee.

Representatives of Deloitte & Touche LLP will be present at the 2006 Annual Meeting and will have an opportunity to make a statement and to respond to appropriate questions raised at the meeting.

Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services of Independent Registered Public Accounting Firm

In accordance with the requirements of Sarbanes-Oxley, the FPL Group Audit Committee Charter and the Audit Committee’s pre-approval policy for services provided by the independent registered public accounting firm, all services performed by Deloitte & Touche are approved in advance by the Audit Committee. Audit and audit-related services specifically identified in an appendix to the pre-approval policy are pre-approved by the Audit Committee each year. This pre-approval allows management to request the specified audit and audit-related services on an as-needed basis during the year, provided any such services are reviewed with the Audit Committee at its next regularly scheduled meeting. Any audit or audit-related service for which the fee is expected to exceed $250,000, or that involves a service not listed on the pre-approval list, must be specifically approved by the Audit Committee prior to commencement of such work. In addition, the Audit Committee approves all services other than audit and audit-related services performed by Deloitte & Touche in advance of the commencement of such work or, in cases which meet the de minimus pre-approval exception established by Sarbanes-Oxley, prior to completion of the audit. The Audit Committee has delegated to the chairman of the committee the right to approve audit, audit-related, tax and other services, within certain limitations, between meetings of the Audit Committee, provided any such decision is presented to the Audit Committee at its next regularly scheduled meeting. The Audit Committee reviews on a quarterly basis a schedule of all services for

213

which Deloitte & Touche has been engaged and the estimated fees for those services. In fiscal year 2005, approximately $27,000 (16% of total Tax Fees and 0.49% of total revenues paid to Deloitte & Touche during 2005) of services included in the Tax Fees category described above were approved by the Audit Committee after the services were rendered, pursuant to the de minimus exception established by Sarbanes-Oxley. No services were provided in fiscal year 2004 pursuant to this exception.

The Audit Committee has determined that the non-audit services provided by Deloitte & Touche during 2005 and 2004 were compatible with maintaining that firm’s independence.

In the event that the date of the 2007 Annual Meeting of Shareholders is more than 30 days earlier than [·] (which would likely be the case if the merger is not completed), proposals on matters appropriate for shareholder consideration consistent with the regulations of the SEC submitted by shareholders for inclusion in the proxy statement and form of proxy for the 2007 Annual Meeting of Shareholders must be received by the Corporate Secretary not later than (i) the deadline disclosed by FPL Group in a Quarterly Report on Form 10-Q filed with the SEC or in another permissible manner, or (ii) if no such deadline is disclosed, a reasonable time before FPL Group begins to print and mail the proxy materials. If the date of the 2007 Annual Meeting of Shareholders is not more than 30 days earlier than [·], proposals for inclusion in the proxy statement and form of proxy for the 2007 Annual Meeting of Shareholders must be received on or before [·].

Under FPL Group’s bylaws, in the event that the date of the 2007 Annual Meeting of Shareholders is more than 30 days earlier or more than 60 days later than [·] (which would likely be the case if the merger is not completed), a shareholder proposal submitted for consideration at the 2007 Annual Meeting of Shareholders, but not for inclusion in FPL Group’s proxy statement and form of proxy must be received by the Corporate Secretary no earlier than 120 days prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of such meeting is first made, and proposals received after such date will be considered untimely and the persons named in the proxies solicited by the FPL Group Board of Directors for the 2007 Annual Meeting of Shareholders may exercise discretionary voting power with respect to any such proposal.

COMPARISON OF STOCKHOLDERS’ RIGHTS

The rights of FPL Group shareholders under the Florida Business Corporation Act (“FBCA”), the FPL Group restated articles of incorporation, as amended (the “FPL Group Charter”), and the FPL Group amended and restated bylaws (the “FPL Group Bylaws”) prior to the completion of the merger are in many instances similar to the rights that they will have as Constellation stockholders following the completion of the merger under the Maryland General Corporation Law (“MGCL”), the Constellation amended and restated charter and the Constellation articles supplementary (together with the Constellation amended and restated charter, the “Constellation Charter”), as in effect prior to the merger and/or after the completion of the merger, as appropriate, and the Constellation amended and restated by-laws (the “Constellation By-laws”), as in effect prior to the merger and/or after the completion of the merger, as appropriate. Below we have summarized the material differences between the current rights of FPL Group shareholders and the rights those shareholders will have as Constellation stockholders following the merger. We have also noted where, if applicable, the rights of current Constellation stockholders will differ after the merger from the rights they now possess. The summary in the following chart is not complete, and it does not identify all differences that may, under given situations, be material to stockholders and is subject in all respects by, and qualified by reference to, the MGCL, the FBCA, the FPL Group Charter, the FPL Group Bylaws, the Constellation Charter and the Constellation By-laws.

Copies of the FPL Group Charter and the FPL Group Bylaws are incorporated by reference into this joint proxy statement/prospectus and will be sent to Constellation stockholders and FPL Group shareholders upon request. Copies of the Constellation Charter, as amended and as currently in effect, and the Constellation By-laws, as amended and as currently in effect, are incorporated by reference into this joint proxy statement/prospectus and will be sent to Constellation stockholders and FPL Group shareholders upon request. See “Where You Can Find More Information” beginning on page 234. Copies of the Constellation Charter, substantially in the form proposed for approval by Constellation stockholders at the annual meeting and proposed to be effective as of the completion of the merger, and the Constellation By-laws, substantially in the form proposed to be effective as of the completion of the merger, are attached as Annex F and Annex G, respectively, to this joint proxy statement/prospectus. The form of Constellation Charter and the form of Constellation By-laws that are attached as Annex F and Annex G, respectively, to this joint proxy statement/prospectus are the form of each such document attached as an exhibit to the merger agreement, except that they include additional modifications agreed to between Constellation and FPL Group since the date of the merger agreement.

Corporate Governance:	Upon completion of the merger, the rights of Constellation stockholders and former FPL Group shareholders will be governed by the MGCL, the Constellation Charter and the Constellation By-laws.	The rights of FPL Group shareholders are currently governed by the FBCA, the FPL Group Charter and the FPL Group Bylaws.

Authorized Capital Stock:	The authorized capital stock of Constellation is discussed under “Certain Legal Information—Description of Constellation Capital Stock—Authorized Capital Stock” beginning on page 232.

The directors are divided into three classes, each class consisting as nearly as possible of one-third of the total number of directors. Directors are elected for three year terms, with one class of directors up for election each year. After the Merger: Under the Constellation Charter, the number of directors shall be no less than seven, with the exact number to be determined as set forth in the Constellation By-laws. The Constellation By-laws provide that the board of directors will consist of at least 7 and no more than 16 directors, with the exact number to be determined by the board of directors. However, the Constellation By-laws provide that, as of the effective time of the merger, until at least the second anniversary of the effective time of the merger (the “Second Anniversary”), the number of directors will be fifteen, consisting of nine FPL Group Designated Directors and six Constellation Designated Directors. The Constellation board of directors will no longer be classified. Directors will be elected at each annual meeting to serve until the next annual meeting and until their successors are elected and qualified.	the exact number to be determined from time to time by the affirmative vote of a majority of the total directors on the board of directors. The FPL Group board of directors is not classified into more than one class. FPL Group currently has 12 directors and will have 10 directors after the annual meeting. Directors are elected at each annual meeting to serve until the next annual meeting. Each director holds office for the term for which he or she is elected and until his or her successor is elected and qualified.

Rights of Preferred Stockholders:	Constellation has not issued any shares of its authorized preferred stock.	FPL Group has not issued any shares of its authorized preferred stock.

Nomination of Directors for Election:	Before the Merger: The Constellation By-laws provide that nominations for directors may be made at annual meetings by the board of directors or by a stockholder who complies with the advance notice procedures in the Constellation By-laws. A stockholder who nominates a director must be a stockholder of record on the date that he or she gives the nomination notice to Constellation. The advance notice procedure in the Constellation By-laws requires that a stockholder’s	The FPL Group Bylaws provide that nominations for directors may be made at annual or special meetings pursuant to FPL Group’s notice of meeting, by the board of directors or by a shareholder who complies with the advance notice procedures in the FPL Group Bylaws. A shareholder who nominates a director must be a shareholder of record on the date he or she gives the nomination notice to FPL Group. The advance notice procedure in the FPL Group Bylaws requires that a shareholder’s notice must

Constellation Stockholder Rights

FPL Group Shareholder Rights

notice must be given timely and in proper written form to Constellation’s Corporate Secretary.

Currently, in order to be timely, the notice must be given to Constellation’s Corporate Secretary not less than 75 days prior to the anniversary date of the notice of the immediately preceding year’s annual meeting.

To be in proper written form, the notice must include, among other things, information on the nominating stockholder and information regarding the nominee required by the proxy rules of the SEC. The notice also must be accompanied by a written consent of the proposed nominee consenting to being named as a nominee and to serving as a director if elected.

After the Merger:

After the merger, in the case of an annual meeting, in order to be timely, the notice must be given to Constellation’s Corporate Secretary not less than 90 days nor more than 120 days prior to the anniversary date of the notice of the immediately preceding year’s annual meeting or, if the annual meeting will be held more than 30 days before or 60 days after that anniversary date, notice must be given no earlier than the 120th day before the meeting and no later than the close of business on the later of the 90th day before the meeting or the 10th day after the first public announcement of the meeting.

In the case of a special meeting, in order to be timely, the notice must be given to Constellation’s Corporate Secretary no earlier than the 120th day before the meeting and no later than the close of business on the later of the 90th day before the meeting or the 10th day after the first public announcement of the meeting.

If the number of directors to be elected at the annual meeting is increased in accordance with the Constellation By-laws and there is no public announcement naming all of the nominees for directors

be given timely and in proper written form to FPL Group’s Corporate Secretary.

For nominations at annual meetings to be timely, notice must be delivered in person or by facsimile, or sent by U.S. certified mail and received, at FPL Group’s principal executive offices not earlier than 120 days and not later than 90 days prior to the anniversary date of the immediately preceding annual meeting. If the date of the annual meeting is more than 30 days earlier, or 60 days later, than such anniversary date, similar timeliness requirements, based on the date of the meeting, apply. Similar requirements apply in order for shareholder nominations at special meetings to be timely.

To be in proper written form, the notice must include, among other things, information on the nominating shareholder and information regarding the nominee required by the proxy rules of the SEC and the rules of the NYSE. The notice must also be accompanied by a written consent of the proposed nominee consenting to being named as a nominee and to serving as a director if elected. See “FPL Group Proposal 2: Election of Directors—Consideration of Director Nominees” beginning on page 189.

219


	Constellation Stockholder Rights	FPL Group Shareholder Rights
	or specifying the size of the increased board of directors made by Constellation at least 90 days prior to the first anniversary of the date of the immediately preceding annual meeting, notice of nominations with respect to nominees for any new positions created by such increase may be given no later than the 10th day after the first public announcement of all of the nominees for directors or of the specific size of the increased board of directors. Until the Second Anniversary, with respect to each election of directors by the stockholders, the board of directors will nominate to fill each position held by an existing Constellation director or an existing FPL Group director, a person designated by a majority of the remaining Constellation or FPL Group directors, as applicable.

Election of Directors:	Before the Merger: The Constellation By-laws currently provide that directors are elected by a plurality of the votes cast at a meeting at which a quorum is present. After the Merger: Pursuant to the Constellation By-laws, after the merger, directors will be elected by a majority of votes cast at a meeting at which a quorum is present unless (i) the number of nominees exceeds the number of directors to be elected, in which case directors will be elected by a plurality of the votes cast, or (ii) a greater vote is required by law, Constellation’s charter or the board of directors from time to time.	The FPL Group Bylaws provide that action on a matter (including the election of directors) shall be approved if the matter receives the affirmative vote of a majority of the total number of shares represented at the meeting at which a quorum is present and entitled to vote on such matter, unless the matter is one upon which the FBCA or other law requires, or permits the board of directors to require, a greater vote, or the FPL Group Charter or the FPL Group Bylaws require a different vote.

Vacancies on the Board of Directors:	Before the Merger: The Constellation By-laws provide that vacancies on the board of directors may be filled only by the vote of a majority of the directors then in office, even if less than a quorum. The Constellation Charter provides that vacancies that result from any cause other than vacancies created by an increase in the number of directors may be filled by the vote of a majority of the entire board of directors, even if less than	The FPL Group Bylaws provide that any vacancies on the board of directors, including any vacancy created by reason of an increase in the number of directors, will be filled by the majority vote of the remaining directors in office. Directors so chosen shall hold office for a term expiring at the next annual meeting of shareholders.

220


	Constellation Stockholder Rights	FPL Group Shareholder Rights
	a quorum, or by a sole remaining director. Any vacancy that results from an increase in the number of directors may be filled only by a majority of the board of directors. The term of any director elected to fill a vacancy serves for the remainder of the full term of the class in which the vacancy occurred and until a successor is elected and qualified. After the Merger: Pursuant to the Constellation By-laws, as of the effective time of the merger, until the Second Anniversary, the board of directors will take all necessary action to ensure that any vacancy in a position on the board that was held by a director designated by Constellation or a director designated by FPL Group be filled by a person designated by a majority of the remaining Constellation or FPL Group directors, as applicable. All other provisions relating to the filling of vacancies on the board of directors remain unchanged after the merger, except that the term of the director elected to fill the vacancy shall be until the next annual meeting of the Constellation stockholders and until his or her successor is elected and qualified.

Removal of Directors:	The Constellation Charter states that a director may be removed only by the holders of a majority of shares of capital stock then entitled to vote at an election of directors and only for cause. “Cause” is defined as dishonesty, fraud, intentional material damage to the property or business of Constellation, commission and conviction of a felony or other actions not meeting the standard of care required of directors under the MGCL.	The FBCA provides that shareholders may remove one or more directors, with or without cause, unless the articles of incorporation provide that directors may be removed only for cause. The FBCA also provides that if a director is to be removed by the shareholders at a meeting of the shareholders, the notice of the meeting must state that the purpose or one of the purposes of the meeting is the removal of the director. The FPL Group Charter provides that a director may be removed from office by a majority vote of the entire board of directors. A director may also be removed by the shareholders, but only for cause and only by an affirmative vote of the holders of at least 75% of the voting power of the then outstanding shares of

221


	Constellation Stockholder Rights	FPL Group Shareholder Rights
		voting stock, voting together as a single class. Except as otherwise provided by law, cause for removal will be construed to exist only if the director whose removal is proposed has been convicted of a felony by a court of competent jurisdiction and such conviction is no longer subject to direct appeal or has been adjudged by a court of competent jurisdiction to be liable for negligence or misconduct in the performance of his or her duty to FPL Group in a matter of substantial importance to FPL Group and such adjudication is no longer subject to direct appeal.

Calling of Meeting of Directors:	Before the Merger: Currently, a meeting of the Constellation board of directors may be called by the Chairman or the President, or in their absence, on order of the Executive Committee, in each case with notice by mail, telephone, facsimile, electronically or in person 48 hours in advance of the meeting. After the Merger: After the effective time of the merger, the Constellation By-laws will allow only the Chairman, the Chief Executive Officer or any two directors to call a meeting with notice by mail, reputable overnight carrier, telephone, electronically or in person 48 hours in advance of the meeting.	The FPL Group Bylaws allow the Chairman of the Board, the President or the Secretary (upon written request by any two directors) to call a board meeting on two days’ notice or a shorter period of time as would be sufficient for the convenient assembly of the directors.

Indemnification of Directors and Officers:	The Constellation Charter includes an indemnification provision under which Constellation is required to indemnify current and former directors and officers (whether serving Constellation or at its request any other entity) to the fullest extent permitted under Maryland law. Other employees and agents shall be indemnified to the extent authorized by the board of directors or the by-laws and permitted by law. Under the Constellation By-laws, Constellation will indemnify all directors, officers and employees to the fullest extent permitted under Maryland law and	Subject to certain limitations, the FBCA provides that a corporation may indemnify any person who is or was a director, officer, employee or agent of the corporation against liability incurred in any proceeding, if such person acted in good faith and reasonably believed that such actions were in the best interest of the corporation or, with respect to any criminal proceeding, if such person had no reasonable cause to believe such action was unlawful. The FBCA also requires a Florida corporation to indemnify such persons to the extent they are successful on the

222

Constellation Stockholder Rights

FPL Group Shareholder Rights

shall pay or reimburse expenses in advance of final disposition of a proceeding.

Subject to certain limitations, the MGCL provides that a corporation may indemnify any person who is or was a director, officer, employee or agent of the corporation against liability incurred in any proceeding to which he or she is

made party by reason of service in such capacity unless:

• the relevant act or omission giving rise to the liability was material to the

matter and was committed in bad faith, or was the result of active and deliberate dishonesty;

• such person received improper personal benefit in money, property or services; or

• in the case of a criminal proceeding, unless such director had reasonable cause to believe that the act or omission giving rise to the liability was unlawful.

Under the Constellation Charter, to the extent permitted by Maryland law, directors and officers are not personally liable to Constellation or any stockholder for monetary damages. Under applicable law, by virtue of such charter provision, a director or officer of Constellation will have no personal liability to Constellation or its stockholders for monetary damages

except to the extent that (i) it is proved that the director or officer actually received an improper personal benefit or profit in money, property or services for the amount of the improper personal benefit or profit in money, property or services actually received or (ii) a judgment or other adjudication adverse to the director or officer is entered in a proceeding based on a finding in the proceeding that the director’s or officer’s action, or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. These

merits or otherwise in defending a proceeding or if a court determines they should be indemnified. It also permits a Florida corporation to advance expenses incurred in defense of a proceeding on certain conditions.

The FBCA also permits a Florida corporation to further indemnify and make advances to such persons by other means (such as by contract or bylaw provision) unless a judgment or other final adjudication establishes that such person’s actions or omissions which were

material to the cause of action constitute any of the following:

• a crime, unless such person had reasonable cause to believe his conduct was lawful or had no reasonable cause to believe it unlawful;

• a transaction from which he derived an improper personal benefit;

• an action in violation of Florida Statutes Section 607.0834 (which section pertains to unlawful distributions to shareholders); or

• willful misconduct or a conscious disregard for the best interests of the corporation in a proceeding by or in the right of the corporation to procure a judgment in its favor or in a proceeding by or in the right of a shareholder.

These broader rights are applicable under the FPL Group Bylaws, which provide as a contract right that each director and officer who is made or is threatened to be made a party to, or was or is called as a witness, or was or is otherwise involved in any proceeding in connection with his or her status as a director or officer will be indemnified and held harmless by FPL Group to the fullest extent permitted under the FBCA. The FPL Group Bylaws also provide for mandatory advancement of expenses subject to certain conditions.

223


	Constellation Stockholder Rights	FPL Group Shareholder Rights
	indemnity provisions survive repeal or amendment for claims arising out of periods in which the provisions were effective. The MGCL also requires a Maryland corporation to indemnify such persons to the extent they are successful on the merits or otherwise in defending a proceeding, or if a court orders that they should be indemnified. It also permits a Maryland corporation to advance expenses incurred in defense of a proceeding on certain conditions. The MGCL also permits a Maryland corporation to further indemnify and make advances to such persons by other means (such as by contract or by-law provision).

Call of Special Meetings of Stockholders:	Before the Merger: The Constellation By-laws provide that a special meeting of the Constellation stockholders may be called by the Chairman, the Chief Executive Officer or a majority of the board of directors. Upon the written request of the holders of shares having not less than a majority of all the votes entitled to be cast at such meeting, the Corporate Secretary must also call a special meeting of stockholders. Notice must be given not less than ten nor more than 90 days before the date of the special meeting. After the Merger: After the merger, the Constellation By-laws will provide that a special meeting of the Constellation stockholders may be called by the Chairman, the Chief Executive Officer, the Corporate Secretary or a majority of the board of directors.	The FBCA provides that a special meeting of shareholders shall be held on call of the board of directors, persons authorized to do so by the articles of incorporation or bylaws or if holders of not less than 10% (or a higher percentage less than 50% required by the articles of incorporation) sign, date and deliver a written demand for such a meeting. Only business within the purpose(s) described in the notice of the special meeting may be conducted at such a meeting. The FPL Group Bylaws provide that a special meeting of the FPL Group shareholders may only be called by the Chairman of the Board, the President or the Secretary of FPL Group or upon the written request of a majority of all of FPL Group’s outstanding stock entitled to vote on the matters to be presented at the meeting.

Stockholders Proposals:	Before the Merger: The Constellation By-laws provide that in order for a stockholder to bring business before the annual meeting, the stockholder must give timely notice in proper written form to Constellation’s Corporate Secretary.	The FPL Group Bylaws provide that in order for a shareholder to propose business before an annual meeting, the shareholder must give timely notice in proper written form to FPL Group’s Corporate Secretary, and must be a shareholder of record on the date that he or she gives the notice.

224


	Constellation Stockholder Rights	FPL Group Shareholder Rights
	Currently, a stockholder’s notice must be delivered to or mailed and received at Constellation’s principal executive offices not less than 75 days prior to the anniversary date of the notice of the previous year’s annual meeting in order to be timely. To be in proper written form, the notice must include, among other things, a brief description of the stockholder proposal, the reasons for making the proposal, the name and address of the stockholder making the proposal, the class and number of shares beneficially owned by such stockholder and an explanation of any material interest such stockholder may have in the subject matter of the proposal. After the Merger: After the merger, in order to be timely, a stockholder’s notice must be given to Constellation’s Corporate Secretary not less than 90 days nor more than 120 days prior to the anniversary date of the notice of the previous year’s annual meeting or, if the annual meeting will be held more than 30 days before or 60 days after that anniversary date, notice must be given no earlier than the 120th day before the meeting and no later than the close of business on the later of the 90th day before the meeting or the 10th day after the first public announcement of the meeting.	In order to be timely, the notice must be delivered in person or by facsimile, or sent by U.S. certified mail and received, at FPL Group’s principal executive offices not earlier than 120 days and not later than 90 days prior to the anniversary date of the immediately preceding annual meeting. If the date of the annual meeting is more than 30 days earlier, or 60 days later, than such anniversary date, similar timeliness requirements, based on the date of the meeting, apply. To be in proper written form, the notice must include, among other things, a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting, the name and address of the shareholder making the proposal, the class and number of shares beneficially owned by such shareholder and an explanation of any material interest such shareholder may have in the proposed business. The notice must also be accompanied by a representation that the shareholder intends to appear in person or by proxy at the meeting to propose such business.

Stockholder Action by Written Consent:	The Constellation Charter is silent with respect to stockholder action by written consent. Under Maryland law, holders of common stock may not take any action by written consent concerning the election of directors unless authorized to do so by the corporation’s charter.	The FPL Group Charter provides that any action required or permitted to be taken by the shareholders of the corporation must be effected at a duly called annual or special meeting and may not be effected by any consent in writing by such shareholders.

Appointment and Removal of Officers:	The Constellation By-laws provide that the officers shall be chosen by the board of directors or by the chief executive officer if so authorized by the board of directors. Officers shall hold their offices for such terms and shall exercise such powers and perform such duties as shall be set out in the Constellation By-laws or	The FPL Group Bylaws provide that the officers shall be appointed by the board of directors or by a duly appointed officer authorized to appoint officers.

Officers shall hold office until their successors are chosen and qualified, or until their earlier resignation or removal. Any officer may be removed by the board of directors at any time with or without cause. Any officer appointed by the Chief Executive Officer may be removed by the Chief Executive Officer at any time with or without cause.

Anti-Takeover Provisions and Interested Stockholders:	Before the Merger: Constellation elected to be subject to Sections 3-803 of the MGCL (relating to the classification of the board of directors), 3-804(b) (relating to the number of directors on the board of directors), 3-804(c) (relating to filling vacancies on the board of directors) and 3-805 (relating to the calling of special meetings of stockholders). The Maryland Business Combination Act, which is contained in the MGCL, provides that unless exempted, a Maryland corporation may not engage in business combinations, including mergers, dispositions of 10% or more of its assets, issuances of shares of stock or other specified transactions, with an “interested stockholder” or an affiliate of an interested stockholder for five years after the most recent date on which the interested stockholder became an interested stockholder, and thereafter unless certain criteria specified in the Maryland Business Combination Act are met. These criteria include approval by an 80% supermajority vote of the stockholders unless the stockholders receive, in any such business combination, a minimum price for the shares, determined in accordance with the provisions of the statute. An interested stockholder is generally a person owning or controlling, directly or indirectly, 10% or more of the voting	Under FBCA Section 607.0902, unless there is a provision in the articles of incorporation or bylaws electing not to be governed by this provision, “control shares” (shares that would otherwise have voting power for the election of directors in certain ranges of ownership over 20%) acquired in a control-share acquisition have the same voting rights as were accorded to the shares before such acquisition only to the extent granted by a resolution approved by the majority of all the votes entitled to be cast by each class or series of the shareholders of the issuing corporation entitled to vote on the matter. FPL Group has not opted out of this provision. FBCA Section 607.0901 provides that, unless a specified exception is met, an interested shareholder (i.e., a person owning 10% or more of a corporation’s outstanding voting stock) may not engage in an affiliated transaction (including a merger or other significant corporate transactions) with a Florida corporation unless such transaction is approved by two-thirds of the voting shares of the corporation excluding the shares beneficially owned by the interested shareholder. This provision is not applicable under certain circumstances, including when: • a majority of the disinterested directors approve the transaction,

power of the outstanding stock of a Maryland corporation. Constellation has not opted out of the Maryland Business Combination Act and therefore was subject to its provisions.

The Maryland Control Share Acquisition Act generally provides that “control shares” of a corporation acquired in a “control share acquisition” shall have no voting rights except to the extent approved by a vote of two-thirds of the votes eligible to be cast on the matter. “Control shares” means shares of stock that, if aggregated with all other shares of

stock previously acquired by the acquiror, would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of the voting power: one-tenth or more but less than one-third, one-third or more but less than a majority, or a majority or more of all voting power. “Control share acquisition” means the acquisition of control shares subject to certain exceptions. If voting rights or control shares acquired in a control share acquisition are not approved at a stockholders’ meeting, then subject to certain conditions and limitations, the issuer may redeem any or all of the control shares for fair value. If voting rights of such control shares are approved at a stockholders’ meeting and the acquiror becomes entitled to vote a majority of the shares of stock entitled to vote, all other stockholders may exercise appraisal rights.

The Constellation By-laws contain a provision exempting any acquisitions of Constellation shares from the Maryland Control Share Acquisition Act. However, the Constellation board of directors may amend its by-laws in the future to repeal

or modify this exemption, in which case any control shares of Constellation acquired in the control share acquisition will be subject to the Maryland Control Share Acquisition Act.

• the corporation has not had more than 300 shareholders of record at any time during the three years prior to the date on which the affiliated transaction was announced,

• the interested shareholder has beneficially owned at least 80% of the outstanding voting shares of the corporation for at least five years prior to the date on which the affiliated transaction was announced,

• the interested shareholder is the beneficial owner of at least 90% of the outstanding voting shares of the

corporation exclusive of shares acquired directly from the corporation in a transaction not approved by a majority of the disinterested directors,

• the corporation is an investment company registered under the Investment Company Act of 1940, or

• in the affiliated transaction, “fair price” consideration is paid to the holders of each class or series of voting shares and certain other conditions are met.

In addition to any affirmative vote required by law, the FPL Group Charter requires that, unless a specified exception dealing with fair price provisions and certain other conditions are met:

• any merger or consolidation of FPL Group or any subsidiary with (a) any Interested Shareholder (as defined below) or (b) any other corporation (whether or not itself an Interested Shareholder) which is, or after such merger or consolidation would be, an affiliate of an Interested Shareholder,

• any sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of

transactions) to or with any Interested Shareholder or any affiliate of any Interested Shareholder of assets of FPL Group or any subsidiary having

FPL Group Shareholder Rights

After the Merger:

Pursuant to the Constellation Charter, Constellation will remain subject to Sections 3-804(b), 3-804(c) and 3-805 but not Section 3-803.

The Constellation board of directors has adopted a resolution exempting the merger with FPL Group from the Maryland Business Combination Act. Constellation has not opted out of the Maryland Business Combination Act and therefore the Maryland Business Combination Act will apply to future

transactions between Constellation and “interested stockholders” unless Constellation exempts such a transaction or transactions or the Constellation board of directors opts out entirely from the statute.

The Constellation By-laws will continue to contain a provision exempting any acquisitions of Constellation shares from the Maryland Control Share Acquisition Act. However, the Constellation board of directors may amend its by-laws in the future to repeal or modify this exemption, in which case any control shares of Constellation acquired in the control share acquisition will be subject to the Maryland Control Share Acquisition Act.

an aggregate fair market value of $10 million or more,

• the issuance or transfer by FPL Group or any subsidiary (in one transaction or a series of transactions) of any securities of FPL Group or any subsidiary to any Interested Shareholder or any affiliate of any Interested Shareholder in exchange for cash, securities or other property (or a combination thereof) having an aggregate fair market value of $10 million or more,

• the adoption of any plan or proposal for the liquidation or dissolution of FPL Group proposed by or on behalf of an Interested Shareholder or any affiliate of any Interested Shareholder,

• any reclassification of securities (including any reverse stock split), or recapitalization of FPL Group, or

• any merger or consolidation of FPL Group with any of its subsidiaries or any other transaction (whether or not with or into or otherwise involving an Interested Shareholder) which has the effect, directly or indirectly, of increasing the proportionate share of the outstanding shares of any class of equity or convertible securities of FPL Group or any subsidiary which is directly or indirectly owned by an Interested Shareholder or any affiliate of any Interested Shareholder;

shall be approved by the affirmative vote of the holders of at least 75% of the voting power of the then outstanding shares of voting stock, voting together as a single class. Such affirmative vote will be required notwithstanding the fact that no vote may be required, or that a lesser percentage may be specified, by law or in any agreement with any national securities exchange or otherwise.

	Constellation Stockholder Rights	FPL Group Shareholder Rights

		The FPL Group Charter provides that an “Interested Shareholder” is any person (other than FPL Group or any subsidiary) who is: • the beneficial owner of more than 10% of the voting power of the outstanding voting stock, • an affiliate of FPL Group and at any time within the two year period immediately prior to the date in question was the beneficial owner of 10% or more of the voting power of the then outstanding voting stock, or • an assignee of or has otherwise succeeded to any shares of voting stock which were at any time within the two-year period immediately prior to the date in question beneficially owned by any Interested Shareholder, if such assignment or succession occurred in the course of a transaction or series of transactions not involving a public offering.

Amendment to Charter and By-laws:	Before the Merger: Currently, the Constellation Charter generally may be amended by the board of directors adopting a resolution setting forth the amendment proposed, followed by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote. The Constellation Charter also provides that Constellation reserves the right to make any amendment to its charter authorized by law, including amendments that alter the contract rights of outstanding stock. Currently, the Constellation By-laws may be amended by a two-thirds vote of the holders of the outstanding shares of Constellation common stock or by a majority of the board of directors. After the Merger: All provisions relating to amendments to Constellation’s Charter will remain unchanged after the merger.	The FBCA provides that unless a corporation’s articles of incorporation provide otherwise, the board of directors may amend certain items of the corporation’s articles of incorporation without shareholder approval. Certain amendments required to have shareholder approval must be recommended by the board of directors and submitted to a vote at a meeting of shareholders, where such amendments must be adopted by a majority of the votes entitled to be cast on the amendment. The FBCA also provides, unless provided otherwise in the articles of incorporation or other provisions of the FBCA, or as expressly provided in bylaws adopted or amended by shareholder action, that the board of directors may amend or repeal the corporation’s bylaws. The FPL Group Charter provides that FPL Group reserves the right to amend, alter, change or repeal any provision contained in the FPL Group Charter in the manner prescribed by statute, and all

	Constellation Stockholder Rights	FPL Group Shareholder Rights
	After the effective time of the merger, the Constellation By-laws will generally provide that amendment requires the affirmative vote of at least 75% of the holders of the outstanding voting shares of Constellation common stock or by a majority of the board of directors. However, Art. II, Section 3, first sentence (relating to calling of special meetings); Art. III, Section 2, first sentence (relating to the number of directors); and Art. III, Section 3 (relating to the filling of board vacancies) may be amended, altered or repealed only by resolution of the board of directors. After the effective time of the merger, certain provisions of the Constellation By-laws relating to its board of directors, board meetings and committees, headquarters and chief executive officer provide that amendment requires approval by the affirmative vote of at least 70%, in some cases, and 90%, in other cases, of the members of the entire board of directors. See “The Proposed Merger—Post-Merger Governance and Management.” beginning on page 145.	rights conferred on shareholders therein are granted subject to this reservation. Notwithstanding the foregoing, the FPL Group Charter contains a supermajority voting requirement that requires a vote of the holders of 75% of the voting stock in respect of any attempted alteration, amendment or repeal of the following, unless unanimously recommended by the board of directors and that board of directors meets certain requirements: • Article VII of the FPL Group Charter (provisions relating to amending the FPL Group Charter and the FPL Group Bylaws), • the provisions of the first sentence of Section 3 of Article III of the FPL Group Charter (which contains the voting rights of common stock), • Article IV of the FPL Group Charter (relating to the board of directors), • Article V of the FPL Group Charter (relating to shareholder voting), and • Article VI of the FPL Group Charter (relating to certain business combinations). The FPL Group Charter and the FPL Group Bylaws provide that the power to adopt, alter, amend or repeal the FPL Group Bylaws is vested in the board of directors. Bylaws adopted by the board of directors may be repealed or changed, and new bylaws may be adopted, by shareholders only if such repeal, change or adoption is approved by the affirmative vote of the holders of at least 75% of the then outstanding voting shares of stock, voting together as a single class.

Preemptive Rights:	Under the Constellation Charter, no Constellation stockholder shall have any preemptive rights.	The FPL Group Charter does not provide for any preemptive rights for FPL Group shareholders.

The FBCA generally provides that shareholders of a Florida corporation are not entitled to appraisal rights if the shares received in a merger are listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc.

WHEREAS, FPL Group, Constellation and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe various conditions to the Merger; and

ARTICLE II

Effect of the Merger on the Capital Stock of the

Constituent Corporations; Exchange of Certificates

SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of FPL Group Common Stock, any shares of Constellation Common Stock or any shares of common stock of Merger Sub:

(a) Cancellation of Certain FPL Group Common Stock. Each share of FPL Group Common Stock that is owned by FPL Group or Constellation shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(b) Conversion of FPL Group Common Stock. Each issued and outstanding share of FPL Group Common Stock (other than shares to be cancelled in accordance with Section 2.01(a)) shall be automatically converted, subject to the prior effectiveness of the Stock Split, into the right to receive one fully paid and nonassessable share of Constellation Common Stock (the “Exchange Ratio”). As of the Effective Time, all such shares of FPL Group Common Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such shares of FPL Group Common Stock shall cease to have any rights with respect thereto, except the right to receive the shares of Constellation Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 2.02(b), and the right to receive dividends and other distributions in accordance with Section 2.02(c), in each case, without interest.

(c) Conversion of Merger Sub Common Stock. Each issued and outstanding share of capital stock of Merger Sub shall be automatically converted into and become one fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation.

SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. As of the Effective Time, Constellation shall enter into an agreement with such bank or trust company as may be mutually agreed to by FPL Group and Constellation (the “Exchange Agent”), which agreement shall provide that Constellation shall deposit with the Exchange Agent as of the Effective Time, in trust for the benefit of the holders of Certificates, certificates representing the shares of Constellation Common Stock (such shares of Constellation Common Stock being hereinafter referred to as the “Merger Consideration”, and together with any dividends or other distributions with respect thereto with a record date after the Effective Time, collectively being hereinafter referred to as the “Exchange Fund”) issuable pursuant to Section 2.01(b) in exchange for the shares of FPL Group Common Stock that were outstanding immediately prior to the Effective Time.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented outstanding shares of FPL Group Common Stock (the “Certificates”) whose

A-3

shares were converted into the right to receive the Merger Consideration pursuant to Section 2.01(b), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as FPL Group and Constellation may reasonably specify) and (ii) instructions for use in surrendering the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Constellation Common Stock that such holder has the right to receive pursuant to the provisions of this Article II and certain dividends or other distributions in accordance with Section 2.02(c), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of FPL Group Common Stock that is not registered in the transfer records of FPL Group, a certificate representing the proper number of shares of Constellation Common Stock may be issued to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other Taxes required by reason of the issuance of shares of Constellation Common Stock to a person other than the registered holder of such Certificate or establish to the satisfaction of Constellation that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration which the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article II and certain dividends or other distributions in accordance with Section 2.02(c). No interest shall be paid or will accrue on the Merger Consideration or any cash payable to holders of Certificates pursuant to the provisions of this Article II.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Constellation Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Constellation Common Stock issuable hereunder in respect thereof, and all such dividends and other distributions shall be paid by Constellation to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable escheat or similar Laws, following surrender of any such Certificate to the Exchange Agent for cancellation there shall be paid to the holder of the certificate representing whole shares of Constellation Common Stock issued in exchange therefor, without interest, (i) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Constellation Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Constellation Common Stock.

(d) No Further Ownership Rights in FPL Group Common Stock. All shares of Constellation Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms of this Article II (and any dividends or other distributions, in each case, pursuant to this Article II) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of FPL Group Common Stock theretofore represented by such Certificates, subject, however, to FPL Group’s obligation to pay any dividends or make any other distributions expressly permitted by the terms of this Agreement with a record date prior to the Effective Time that may have been declared or made by FPL Group on such shares of FPL Group Common Stock that remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of FPL Group of the shares of FPL Group Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Constellation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II, except as otherwise provided by Law.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates for 12 months after the Effective Time shall be delivered to Constellation, upon

A-4

demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Constellation for payment of their claim for Merger Consideration, any dividends or other distributions with respect to Constellation Common Stock.

(f) No Liability. None of Constellation, the Surviving Corporation or the Exchange Agent or any of their respective directors, officers, employees and agents shall be liable to any person in respect of any shares of Constellation Common Stock, any dividends or other distributions with respect thereto, in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate shall not have been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration or any dividends or other distributions payable to the holder of such Certificate would otherwise escheat to or become the property of any Governmental Authority), any such Merger Consideration, dividends or other distributions in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of Constellation, free and clear of all claims or interest of any person previously entitled thereto.

(g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Constellation, on a daily basis. Any interest and other income resulting from such investments shall be paid to Constellation.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Constellation or the Exchange Agent, the posting by such person of a bond in such reasonable amount as Constellation or the Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and, if applicable, any unpaid dividends and distributions on shares of Constellation Common Stock deliverable in respect thereof, in each case pursuant to this Agreement.

(i) Withholding Taxes. Each of the parties and the Exchange Agent will be entitled to deduct and withhold from amounts otherwise payable under this Article II any amounts that it is required to deduct and withhold with respect to such payments under any provision of Tax Law. Any amounts so deducted and withheld will be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

ARTICLE III

A-5

(i) Each of Constellation and its subsidiaries, including Merger Sub, is duly organized, validly existing and in good standing (with respect to jurisdictions that recognize the concept of good standing) under the Laws of its jurisdiction of organization and has full power and authority to conduct its business as and to the extent now conducted and to own, use and lease its assets and properties, except for such failures to be so organized, existing and in good standing (with respect to jurisdictions that recognize the concept of good standing) or to have such power and authority that, individually or in the aggregate, have not had and would not reasonably be expected to have a material adverse effect on Constellation. Each of Constellation and its subsidiaries, including Merger Sub, is duly qualified, licensed or admitted to do business and is in good standing (with respect to jurisdictions that recognize the concept of good standing) in each jurisdiction in which the ownership, use or leasing of its assets and properties, or the conduct or nature of its business, makes such qualification, licensing or admission necessary, except for such failures to be so qualified, licensed or admitted and in good standing (with respect to jurisdictions that recognize the concept of good standing) that, individually or in the aggregate, have not had and would not reasonably be expected to have a material adverse effect on Constellation. Section 3.01(a) of the Constellation Disclosure Letter sets forth as of the date of this Agreement the name and jurisdiction of organization of each material subsidiary of Constellation.

For purposes of this Agreement:

(A) “Joint Venture” of a person shall mean any person that is not a subsidiary of such first person, in which such first person or one or more of its subsidiaries owns directly or indirectly any share, capital stock, partnership, membership or similar interest of any person or any Option therefor (together, “Equity Interests”), other than Equity Interests that represent less than 5% of each class of the outstanding voting securities or other Equity Interests of such second person; and

(B) “Constellation Joint Venture” shall mean any Joint Venture of Constellation or any of its subsidiaries in which the invested capital associated with Constellation’s or its subsidiaries’ interest exceeds $100,000,000, as reasonably determined by Constellation.

(iii) Except for interests in the subsidiaries of Constellation, the Constellation Joint Ventures and interests acquired after the date of this Agreement without violating any covenant contained herein, Constellation does not directly or indirectly own any shares of capital stock, other voting securities or Equity Interests in any person, in which the invested capital associated with such interest individually as of the date of this Agreement exceeds $100,000,000, as reasonably determined by Constellation. Merger Sub (A) does not directly or indirectly own any shares of capital stock, other voting securities or Equity Interests in any person and (B) does not hold and has not held any material assets or incurred any material liabilities.

(b) Capital Stock.

The authorized capital stock of Merger Sub consists of 1,000 shares of common stock, par value $.01 per share, of which 100 shares are issued and outstanding, all of which are beneficially owned by Constellation.

(ii) Except as set forth in Section 3.01(b)(i) above, at the close of business on December 12, 2005, no shares of capital stock or other voting securities or Equity Interests of Constellation were issued, reserved for issuance, outstanding or held by Constellation in its treasury.

FPL Group has established risk parameters, limits and guidelines in compliance with the risk management policies approved by the Finance and Investment Committee of the Board of Directors of FPL Group (the “FPL Group Trading Guidelines”) and the Chief Executive Officer of FPL Group has approved a VaR limit as set forth in Section 3.02(q) of the FPL Group Disclosure Letter (the “FPL Group Approved VaR Limit”). Compliance with the FPL Group Trading Guidelines is monitored by the Exposure Management Committee of FPL Group and reported to the Chief Executive Officer of FPL Group and is reviewed annually with the Finance and Investment Committee of the Board of Directors of FPL Group. FPL Group has provided the FPL Group Trading Guidelines to Constellation prior to the date of this Agreement. As of the date of this Agreement, (i) FPL Group’s VaR is in compliance with the FPL Group Approved VaR Limit, and FPL Group and its subsidiaries are operating in compliance with the FPL Group Trading Guidelines in all material respects and (ii) the aggregate net positions in the trading and managed hedge portfolio (i.e., mark-to-market positions excluding non-qualifying hedges) of FPL Group and its subsidiaries would not reasonably be expected to result in a material loss to FPL Group and its subsidiaries, taken as a whole, based on market prices in existence as of the date of this Agreement. From September 30, 2005, to the date of this Agreement, neither FPL Group nor any of its subsidiaries has, in accordance with its mark-to-market accounting policies, experienced an aggregate net trading loss in FPL Group’s trading and managed hedge portfolio (i.e., mark-to-market positions excluding non-qualifying hedges) that would be material to FPL Group and its subsidiaries taken as a whole. For purposes of this Section 3.01(q) and Section 4.02(h), “VaR” shall mean the value-at-risk of the mark-to-market trading and managed hedge portfolio (i.e., mark-to-market positions excluding non-qualifying hedges) of FPL Group and its marketing and trading subsidiaries based on a two standard deviation move in prices and a one-day holding period.

(r) Vote Required. Assuming the accuracy of the representation and warranty of Constellation contained in Section 3.01(s), (i) the affirmative vote of at least a majority of the outstanding shares of FPL Group Common Stock entitled to be cast at the FPL Group Stockholder Meeting (the “FPL Group Shareholder Approval”) is the only vote or consent of the holders of any class or series of the capital stock of FPL Group or its subsidiaries required to approve this Agreement and (ii) except as set forth in clause (i) of this sentence, the affirmative vote or consent of the holders of any class or series of the capital stock of FPL Group or its subsidiaries is not necessary to consummate any of the transactions contemplated by this Agreement.

(s) Ownership of Constellation Capital Stock. Neither FPL Group nor any of its subsidiaries or other affiliates beneficially owns any shares of Constellation Common Stock or any other class or series of Constellation Capital Stock. None of FPL Group or any of its “affiliates” or “associates” is, or has been within the two-year period immediately prior to the date of this Agreement, an “interested stockholder” of Constellation as those terms are defined in Section 3-601 of the MGCL.

(t) State Anti-Takeover Statutes. Assuming the accuracy of the representation and warranty of Constellation contained in Section 3.01(s), FPL Group has taken all necessary actions, if any, so that the provisions of Article VI of the restated articles of incorporation of FPL Group, as amended through the date of this Agreement, and the provisions of Sections 607.0901 and 607.0902 of the FBCA will not, before the termination of this Agreement, apply to this Agreement, the Merger or the other transactions contemplated hereby.

(u) Joint Venture Representations. Each representation or warranty made by FPL Group in this Section 3.02 relating to a FPL Group Joint Venture that is neither operated nor managed by FPL Group or a FPL Group subsidiary shall be deemed made only to the knowledge of FPL Group.

(v) Opinion of Financial Advisor. FPL Group has received the opinions of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Lehman Brothers Inc., each dated the date of this Agreement to the effect that, as of the date of this Agreement and based upon and subject to the matters set forth therein, the

A-32

Exchange Ratio, assuming the prior effectiveness of the Stock Split, is fair from a financial point of view to the shareholders of FPL Group.

(w) Brokers. No broker, investment banker, financial advisor or other person, other than Merrill Lynch, Pierce, Fenner & Smith Incorporated and Lehman Brothers Inc., the fees and expenses of which will be paid by FPL Group, is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the Merger and the other transactions contemplated by this Agreement based upon arrangements made by or on behalf of FPL Group.

(x) Rights Agreement. FPL Group has taken all actions necessary so that the execution of this Agreement and the consummation of the Merger and other transactions contemplated hereby do not and will not result in the grant of any increased rights to any person under the FPL Group Rights Agreement or enable, require or cause the FPL Group Rights to be exercised, distributed or triggered. The Board of Directors of FPL Group has approved an amendment to the FPL Group Rights Agreement to provide that the FPL Group Rights will terminate upon the Effective Time.

FPL Group shall use its reasonable best efforts to cause to be delivered to Constellation two letters from FPL Group’s independent accountants, one dated a date within two business days before the date on which the Form S-4 shall become effective and one dated a date within two business days before the Closing Date, each addressed to Constellation, in form and substance reasonably satisfactory to Constellation and customary in scope and substance for comfort letters delivered by independent public accountants in connection with registration statements similar to the Form S-4.

SECTION 5.03. Letters of Constellation’s Accountants. Constellation shall use its reasonable best efforts to cause to be delivered to FPL Group two letters from Constellation’s independent accountants, one dated a date within two business days before the date on which the Form S-4 shall become effective and one dated a date within two business days before the Closing Date, each addressed to FPL Group, in form and substance reasonably satisfactory to FPL Group and customary in scope and substance for comfort letters delivered by independent public accountants in connection with registration statements similar to the Form S-4.

SECTION 5.04. Access to Information; Confidentiality; Effect of Review. (a) Access. Subject to the Confidentiality Agreement, to the extent permitted by applicable Law each of FPL Group and Constellation shall, and shall cause each of its respective subsidiaries to, afford to the other party, and to the officers, employees, accountants, counsel, financial advisors and other representatives of such other party, pursuant to integration policies to be adopted by the integration leaders designated by each of Constellation and FPL Group, reasonable access during normal business hours during the period prior to the Effective Time to all their respective properties, books, contracts, commitments, personnel and records and, during such period, to the extent permitted

A-48

by applicable Law, each of FPL Group and Constellation shall, and shall cause each of its respective subsidiaries to, (i) confer on a regular and reasonable basis with one or more representatives of the other party to discuss material operational and regulatory matters and the general status of its ongoing operations for purposes related to the completion of the transactions contemplated by this Agreement (including, without limitation, a party’s assessment of the proper accounting for such transactions, any public disclosures that a party is required to make regarding such transactions and reasonable access to management and systems needed for integration planning) or the fulfillment of its obligations under this Agreement, (ii) advise the other party of any change or event that has had or would reasonably be expected to have a material adverse effect on such party and (iii) furnish promptly all other information concerning its business, properties and personnel, in each case as such other party may reasonably request in connection with activities relating to the completion of the transactions contemplated by this Agreement or the fulfillment of its obligations under this Agreement; provided, however, that (A) no actions shall be taken pursuant to this Section 5.04(a) that (x) would result in a waiver of the attorney/client privilege or (y) could reasonably be expected to result in violation of applicable Law, including antitrust Laws, and (B) each of the parties shall, without being deemed to have violated this Section 5.04, be permitted to continue to limit the other party’s access to its wholesale competitive supply business, retail competitive supply business and wind business to aggregated information per business line that takes due account of competitive considerations. Subject to the Confidentiality Agreement, to the extent permitted by applicable Law, each of FPL Group and Constellation, so long as consistent with its confidentiality obligations under its applicable agreements, shall use its reasonable best efforts to cause each FPL Group Joint Venture and each Constellation Joint Venture, respectively, to afford access and take such other actions as would be required under the previous sentence as if it was a subsidiary of FPL Group or Constellation, as the case may be. Notwithstanding the foregoing, if a party requests access to proprietary information of the other party, the disclosure of which could reasonably be expected to materially impair the competitive position or operations of the other party if the Closing were not to occur (giving effect to the requesting party’s obligations under the Confidentiality Agreement), such information shall only be disclosed to the extent reasonably agreed upon by the chief financial officers (or their designees) of FPL Group and Constellation. Section 5.04(a) of each of the Constellation Disclosure Letter and the FPL Group Disclosure Letter sets forth additional procedures regarding access to information. All information exchanged pursuant to this Section 5.04(a) shall be subject to the Confidentiality Agreement.

(b) Effect of Review. No review pursuant to this Section 5.04 shall have an effect for the purpose of determining the accuracy of any representation or warranty given by any of the parties hereto to any of the other parties hereto.

SECTION 5.05. Regulatory Matters; Reasonable Best Efforts. (a) Regulatory Approvals. Each party hereto shall cooperate and promptly prepare and file all necessary documentation, applications, notices, petitions and filings, and shall use reasonable best efforts to obtain all necessary approvals and authorizations of all Governmental Authorities, necessary or advisable to consummate and make effective, in the most expeditious manner reasonably practicable, the Merger and the other transactions contemplated by this Agreement, including the FPL Group Required Statutory Approvals and the Constellation Required Statutory Approvals; provided, however, that FPL Group shall have primary responsibility for the preparation and filing of any related applications, filings or other materials with the FPSC and, provided further, that Constellation shall have primary responsibility for the preparation and filing of any related applications, filings or other materials with the MPSC. FPL Group shall have the right to review and approve in advance all characterizations of the information relating to FPL Group, on the one hand, and Constellation shall have the right to review and approve in advance all characterizations of the information relating to Constellation, on the other hand, in either case, that appear in any application, notice, petition or filing made in connection with the Merger or the other transactions contemplated by this Agreement. FPL Group and Constellation agree that they will consult and cooperate with each other with respect to the obtaining of all such necessary approvals and authorizations of Governmental Authorities.

(b) Further Actions. Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things reasonably necessary

A-49

or advisable to consummate and make effective, in the most expeditious manner reasonably practicable, the Merger and the other transactions contemplated by this Agreement, including (i) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, and (ii) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement.

Notwithstanding the foregoing, as used in this Section 5.05, “reasonable best efforts” shall not include nor require any party to (i) sell, or agree to sell, hold or agree to hold separate, or otherwise dispose or agree to dispose of any asset, in each case if such sale, separation or disposition or agreement with respect thereto would, individually or in the aggregate, reasonably be expected to have a material adverse effect on such party or on Constellation and its prospective subsidiaries, taken as a whole, or (ii) conduct or agree to conduct its business in any particular manner if such conduct or agreement with respect thereto would individually or in the aggregate, reasonably be expected to have a material adverse effect on such party or on Constellation and its prospective subsidiaries, taken as a whole.

(c) State Anti-Takeover Statutes. Without limiting the generality of Section 5.05(b), FPL Group and Constellation shall (i) take all action necessary to ensure that no state anti-takeover statute or similar statute or regulation is or becomes applicable to the Merger, this Agreement or any of the other transactions contemplated by this Agreement and (ii) if any state anti-takeover statute or similar statute or regulation becomes applicable to the Merger, this Agreement or any other transaction contemplated by this Agreement, take all action necessary to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as reasonably practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and the other transactions contemplated by this Agreement.

SECTION 5.06. FPL Group Employee Stock Options, FPL Group Restricted Stock, FPL Group Other Equity-Based Awards, and FPL Group Stock Plans. (a) Prior to the Effective Time, the Board of Directors of FPL Group (or, if appropriate, any committee administering the FPL Group Stock Plans) shall adopt such resolutions or take such other actions as may be required to effect the following:

(i) adjust the terms of all outstanding FPL Group Employee Stock Options granted under the FPL Group Stock Plans, whether vested or unvested, as necessary to provide that, at the Effective Time, each FPL Group Employee Stock Option outstanding immediately prior to the Effective Time shall be converted automatically, subject to the prior effectiveness of the Stock Split, into an option to acquire, on the same terms and conditions as were applicable under such FPL Group Employee Stock Option, including vesting, a number of shares of Constellation Common Stock equal to the number of shares of FPL Group Common Stock subject to such FPL Group Employee Stock Option immediately before the Effective Time at an exercise price per share equal to the exercise price per share of such FPL Group Employee Stock Option immediately before the Effective Time (each, as so adjusted, a “FPL Group Adjusted Option”);

(ii) provide that each share of FPL Group Restricted Stock shall be converted, subject to the prior effectiveness of the Stock Split, into one share of Constellation Restricted Stock (each such share, as so adjusted, the “FPL Group Adjusted Restricted Stock”), on the same terms and conditions as were applicable to such share of FPL Group Restricted Stock, including vesting;

(iii) adjust the terms of all outstanding FPL Group Other Equity-Based Awards, whether vested or unvested, as necessary to provide that each such FPL Group Other Equity-Based Award outstanding immediately prior to the Effective Time shall be amended and converted, subject to the prior effectiveness of the Stock Split, into an equity or equity-based award in respect of a number of shares of Constellation Common Stock (each, a “FPL Group Adjusted Other Equity-Based Award”) equal to the number of shares of FPL Group Common Stock subject to such FPL Group Other Equity-Based Award immediately before the Effective Time, on the same terms and conditions as were applicable to such FPL Group Other Equity-Based Award, including vesting, and, if such FPL Group Other Equity-Based Award is subject to an

A-50

exercise or subscription price, the exercise or subscription price per share of such FPL Group Adjusted Other Equity-Based Award shall be equal to the exercise or subscription price per share of such FPL Group Other Equity-Based Award immediately before the Effective Time (rounded up to the nearest whole cent);

(iv) use reasonable best efforts to ensure (A) that the conversion pursuant to Section 2.01(b) of any FPL Group Common Stock held by any director or officer of FPL Group who is subject to Section 16(a) of the Exchange Act, (B) the conversion pursuant to this Section 5.06(a) of any FPL Group Employee Stock Options held by any such director or officer of FPL Group into FPL Group Adjusted Options and (C) the conversion pursuant to this Section 5.06(a) of any FPL Group Restricted Stock or FPL Group Other Equity-Based Awards held by any such director or officer of FPL Group into FPL Group Adjusted Restricted Stock or FPL Group Adjusted Other Equity-Based Awards, in each case will be eligible for exemption under Rule 16b-3(e); and

(v) make such other changes to the FPL Group Stock Plans as FPL Group and Constellation may agree are appropriate to give effect to the Merger.

(b) As soon as practicable after the Effective Time, Constellation shall deliver to the holders of FPL Group Adjusted Options, FPL Group Adjusted Restricted Stock and FPL Group Adjusted Other Equity-Based Awards (collectively, the “FPL Group Adjusted Awards”) appropriate notices setting forth such holders’ rights pursuant to the FPL Group Stock Plans and the agreements evidencing the grants of such FPL Group Adjusted Awards, and stating that such FPL Group Adjusted Awards and the related agreements shall be assumed by Constellation and shall continue in effect on the same terms and conditions, including with respect to vesting (subject to the adjustments required by this Section 5.06 after giving effect to the Merger).

(c) Except as otherwise contemplated by this Agreement and except to the extent required under the respective terms of the FPL Group Employee Stock Options, FPL Group Restricted Stock and FPL Group Other Equity-Based Awards, all restrictions or limitations on transfer and vesting with respect to such FPL Group Employee Stock Options, FPL Group Restricted Stock and FPL Group Other Equity-Based Awards, to the extent that such restrictions or limitations shall not have already lapsed, shall remain in full force and effect with respect to the applicable FPL Group Adjusted Awards after giving effect to the Merger and the assumption of such awards by Constellation as set forth above.

(d) Notwithstanding any provision of Section 5.06(a), FPL Group Employee Stock Options, FPL Group Restricted Stock and FPL Group Other Equity-Based Awards granted after the date of this Agreement, as permitted by Section 4.02(d), (i) shall not vest on the FPL Group Stockholder Approval or otherwise in connection with the occurrence of the transactions contemplated hereby, (ii) shall not be cashed out or terminated in connection with the occurrence of the transactions contemplated hereby, (iii) shall not entitle the holders thereof to any future grants of stock options or other awards (including any “replacement option” grants), (iv) shall be converted at the Effective Time into FPL Group Adjusted Awards and (v) shall otherwise remain in full force and effect and be eligible to become vested in accordance with their terms following the Effective Time.

(e) At the Effective Time, by virtue of the Merger, the FPL Group Stock Plans shall be deemed assumed by Constellation, with the result that all obligations of FPL Group under the FPL Group Stock Plans, including with respect to awards outstanding at the Effective Time under the FPL Group Stock Plans, shall be obligations of Constellation following the Effective Time. Prior to the Effective Time, Constellation shall take all necessary actions for the assumption of the FPL Group Stock Plans by Constellation, including the reservation, issuance and listing of Constellation Common Stock in a number at least equal to the number of shares of Constellation Common Stock that will be subject to FPL Group Adjusted Awards. As promptly as practicable following the Effective Time, Constellation shall use reasonable best efforts to prepare and file with the SEC a registration statement on Form S-8 (or another appropriate form) registering a number of shares of Constellation Common Stock determined in accordance with the preceding sentence. Such registration statement shall be kept effective (and the current status of the prospectus or prospectuses required thereby shall be maintained)

A-51

at least for so long as FPL Group Adjusted Awards remain outstanding.

(v) each share of Constellation Restricted Stock and each Constellation Restricted Unit granted under the Management Long-Term Incentive Plan or the 1995 Long-Term Incentive Plan on or prior to the date of this Agreement that is outstanding immediately prior to the Effective Time, regardless of whether or not such award is a Constellation Performance Stock Award, in each case, shall be adjusted at the Effective Time in accordance with Section 5.18 to reflect the Stock Split and (A) each such share of Constellation Restricted Stock and each such Constellation Restricted Unit that becomes vested at the Effective Time pursuant to the terms of the applicable Constellation Stock Plan shall immediately vest at the Effective Time, with the holder of such vested share of Constellation Restricted Stock or vested Constellation Restricted Unit becoming entitled, immediately following the Effective Time, to receive, in full satisfaction

SECTION 5.08. Employee Matters. (a) Following the Effective Time, Constellation will (subject to Sections 5.06, 5.07, this Section 5.08 and Section 5.09), and will cause its subsidiaries to (i) honor all obligations under any contracts, agreements, collective bargaining agreements, plans and commitments (as such may be amended in accordance with this Agreement) of FPL Group and its subsidiaries that exist on the date of this Agreement (or as established or amended in accordance with or permitted by this Agreement) that apply to any current or former employee, or current or former director, of FPL Group or any of its subsidiaries and (ii) continue to honor all obligations under any contracts, agreements, collective bargaining agreements, plans and commitments (as such may be amended in accordance with this Agreement) of Constellation and its subsidiaries that exist on the date of this Agreement (or as established or amended in accordance with or permitted by this Agreement) that apply to any current or former employee, or current or former director, of

A-53

Constellation or any of its subsidiaries, including the obligation to issue “replacement options” as described in Section 4.01(i) of the Constellation Disclosure Letter; provided, however, that the undertakings set forth in this Section 5.08(a) are not intended to prevent Constellation and its subsidiaries from enforcing such contracts, agreements, collective bargaining agreements, plans and commitments (as such may be amended in accordance with this Agreement) in accordance with their respective terms, including any reserved right to amend, modify, suspend, revoke or terminate any such contract, agreement, collective bargaining agreement or commitment.

(b) At the Effective Time, it shall be the intent of Constellation, that (subject to obligations under applicable Law and applicable collective bargaining agreements) (i) any reductions in the employee work force of Constellation and its subsidiaries shall be made on a fair and equitable basis (as determined by Constellation and its subsidiaries), in light of the circumstances and the objectives to be achieved, giving consideration to previous work history, job experience and qualifications and such other factors as Constellation and its subsidiaries consider appropriate, without regard to whether employment prior to the Effective Time was with FPL Group and its subsidiaries or Constellation and its subsidiaries, and any employees whose employment is terminated or whose jobs are eliminated by Constellation or any of its subsidiaries during such period shall be entitled to participate on a fair and equitable basis (as determined by Constellation and its subsidiaries) in the job opportunity and employment placement programs offered by Constellation or any of its subsidiaries for which they are eligible and (ii) employees shall be entitled to participate in all job training, career development and educational programs of Constellation and its subsidiaries for which they are eligible, and shall be entitled to fair and equitable consideration (as determined by Constellation and its subsidiaries) in connection with any job opportunities with Constellation and its subsidiaries, in each case without regard to whether employment prior to the Effective Time was with FPL Group and its subsidiaries or Constellation and its subsidiaries.

(c) Subject to its obligations under applicable Law and applicable collective bargaining agreements, Constellation and its subsidiaries shall give credit under each of their respective employee benefit plans, programs and arrangements to employees for all service prior to the Effective Time with FPL Group or its subsidiaries, as applicable, or any predecessor employer (to the extent that such credit was given by FPL Group or any of its subsidiaries, as applicable) (“Pre-Closing Service”) for all purposes for which such service was taken into account or recognized by FPL Group or its subsidiaries, as applicable (including for benefit accrual purposes under any defined benefit pension plans), but not to the extent crediting such service would result in duplication of benefits. Notwithstanding the foregoing, Constellation and its subsidiaries shall only be required to provide credit for Pre-Closing Service for benefit accrual purposes under a defined benefit pension plan if such plan is a FPL Group Employee Benefit Plan or if such plan has assumed the assets or liabilities of a FPL Group Employee Benefit Plan.

SECTION 5.09. Indemnification, Exculpation and Insurance. (a) Constellation agrees that, to the fullest extent permitted under applicable Law, all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors, officers, employees or fiduciaries under benefit plans currently indemnified by FPL Group and its subsidiaries or by Constellation and its subsidiaries, as provided in their respective articles or certificates of incorporation, by-laws (or comparable organizational documents) or other agreements providing indemnification shall survive the Merger and shall continue in full force and effect in accordance with their terms. In addition, from and after the Effective Time, directors, officers, employees and fiduciaries under benefit plans currently indemnified by FPL Group or its subsidiaries or by Constellation and its subsidiaries who become or remain directors, officers, employees or fiduciaries under benefit plans of Constellation will be entitled to the indemnity rights and protections afforded to directors, officers, employees and fiduciaries under benefit plans of Constellation.

(b) For six years after the Effective Time, Constellation shall, or shall cause the Surviving Corporations to, maintain in effect the directors and officers liability (and fiduciary) insurance policies currently maintained by Constellation and FPL Group covering acts or omissions occurring prior to the Effective Time with respect to those persons who are currently covered by Constellation’s or FPL Group’s, as the case may be, directors and officers liability insurance policies on terms with respect to such coverage and in amounts no less favorable than those set forth in the relevant policy in effect on the date of this Agreement.

A-54

If such insurance coverage cannot be maintained, Constellation shall, or shall cause the Surviving Corporation to, maintain the most advantageous policies of directors and officers insurance otherwise obtainable.

(c) The provisions of Section 5.09(a) (i) are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise.

SECTION 5.10. Fees and Expenses. (a) Except as provided in this Section 5.10, all fees and expenses incurred in connection with the Merger, this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated, except that each of Constellation and FPL Group shall bear and pay one-half of the costs and expenses incurred in connection with (i) the filing, printing and mailing of the Form S-4 and the Joint Proxy Statement (including SEC filing fees) and (ii) the filings of the premerger notification and report forms under the HSR Act (including filing fees).

(b) In the event that

(i) following the Constellation Stockholder Approval, a Constellation Takeover Proposal shall have been made known to the Board of Directors or any senior executive officer of Constellation or shall have been made directly to Constellation’s stockholders or any person shall have publicly announced an intention (whether or not conditional) to make a Constellation Takeover Proposal and thereafter this Agreement is terminated by either Constellation or FPL Group pursuant to Section 7.01(b)(i),

(ii) prior to or during the Constellation Stockholders Meeting (or any subsequent meeting of Constellation stockholders at which it is proposed that the Constellation Charter Amendment or the Share Issuance be approved), a Constellation Takeover Proposal shall have been publicly disclosed or any person shall have publicly announced an intention (whether or not conditional) to make a Constellation Takeover Proposal and thereafter this Agreement is terminated by either Constellation or FPL Group pursuant to Section 7.01(b)(iii), or

(iii) this Agreement is terminated by FPL Group pursuant to Section 7.01(f)(i) then subject to clauses (A), (B) and (C) below, Constellation shall pay FPL Group, upon the first to occur of such events, a fee equal to $425,000,000 (the “Constellation Termination Fee”) in immediately available funds minus any amounts as may have been previously paid by Constellation pursuant to Section 5.10(d) and any fee as may have been previously paid pursuant to clause (B) of the next sentence.

Notwithstanding any provision herein to the contrary:

(A) no Constellation Termination Fee shall be payable to FPL Group

(I) pursuant to Section 5.10 (b)(i) unless prior to the 12 month anniversary of such termination Constellation or any of its subsidiaries enters into any Constellation Acquisition Agreement or consummates any Constellation Takeover Proposal,

(II) pursuant to Section 5.10 (b)(ii) unless prior to the 24 month anniversary of such termination Constellation or any of its subsidiaries enters into any Constellation Acquisition Agreement or consummates any Constellation Takeover Proposal or

(III) pursuant to Section 5.10 (b)(iii) unless (x) a Constellation Takeover Proposal shall have been made known to the Board of Directors or any senior executive officer of Constellation or shall have been made directly to Constellation’s stockholders or any person shall have publicly announced an intention (whether or not conditional) to make a Constellation Takeover Proposal, (y) thereafter there shall occur a Constellation Adverse Recommendation Change and (z) prior to the 24 month anniversary of the termination of this

(B) If (x) a Constellation Takeover Proposal shall have been made known to the Board of Directors or any senior executive officer of Constellation or shall have been made directly to Constellation’s stockholders or any person shall have publicly announced an intention (whether or not conditional) to make a Constellation Takeover Proposal, (y) thereafter there shall occur a Constellation Adverse Recommendation Change and (z) prior to the termination of this Agreement by FPL Group pursuant to Section 7.01(f)(i), the Constellation Stockholders Meeting shall have occurred and the Constellation Stockholder Approval shall not have been obtained, then Constellation shall promptly after such Constellation Stockholder Approval was not obtained pay to FPL Group a fee equal to $100,000,000 (which fee shall not be reduced by any amounts paid by Constellation pursuant to Section 5.10(d)), and

(C) if this Agreement is terminated by FPL Group pursuant to Section 7.01(f)(i) as a result of the Board of Directors of Constellation (or any committee thereof) having made a Constellation Adverse Recommendation Change primarily due to adverse conditions, events or actions of or relating to FPL Group that would result in the failure of a condition to each of Constellation’s and Merger Sub’s obligations to effect the Merger and the other transactions contemplated hereby to be satisfied, then the Constellation Termination Fee and/or the $100,000,000 fee described in clause (B) above shall not be payable and in any related judicial, court or tribunal proceeding, whether brought or initiated by FPL Group or Constellation, Constellation shall have the burden of proving that such Constellation Adverse Recommendation Change was primarily due to such adverse conditions, events or actions of or relating to FPL Group.

In any event, the aggregate amount paid by Constellation pursuant to this Section 5.10(b) and Section 5.10(d) shall not exceed $425,000,000.

Any Constellation Termination Fee or other amount that becomes payable by Constellation pursuant to this Section 5.10(b) shall be paid as promptly as possible after the occurrence of the last requirement triggering such payment hereunder by wire transfer of immediately available funds.

(i) following the FPL Group Shareholder Approval, a FPL Group Takeover Proposal shall have been made known to the Board of Directors or any senior executive officer of FPL Group or shall have been made directly to FPL Group’s shareholders or any person shall have publicly announced an intention (whether or not conditional) to make a FPL Group Takeover Proposal and thereafter this Agreement is terminated by either Constellation or FPL Group pursuant to Section 7.01(b)(i),

(ii) prior to or during the FPL Group Shareholders Meeting (or any subsequent meeting of FPL Group shareholders at which it is proposed that this Agreement be approved), a FPL Group Takeover Proposal shall have been publicly disclosed or any person shall have publicly announced an intention (whether or not conditional) to make a FPL Group Takeover Proposal and thereafter this Agreement is terminated by either Constellation or FPL Group pursuant to Section 7.01(b)(ii), or

A-56

available funds minus any amounts as may have been previously paid by FPL Group pursuant to Section 5.10(e) and any fee as may have been previously paid pursuant to clause (B) of the next sentence.

Notwithstanding any provision herein to the contrary:

(A) no FPL Group Termination Fee shall be payable to Constellation

Form of Affiliate Letter

Dear Sirs:

The undersigned, a holder of shares of common stock, par value $.01 per share (the “FPL Group Common Stock”), of FPL Group, Inc., a Florida corporation (the “Company”), acknowledges that the undersigned may be deemed an “affiliate” of the Company within the meaning of Rule 145 (“Rule 145”) promulgated under the Securities Act of 1933, as amended (the “Securities Act”), by the Securities and Exchange Commission (the “SEC”). Pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”) dated as of December 18, 2005, among the Company, Constellation Energy Group, Inc., a Maryland corporation (“Constellation”), and CF Merger Corporation, a Florida corporation and a wholly owned subsidiary of Constellation (“Merger Sub”), Merger Sub will be merged with and into the Company (the “Merger”) and each share of FPL Group Common Stock will be converted into one share of common stock, no par value per share, of Constellation (the “Constellation Common Stock”). Capitalized terms used but not defined in this letter have the meanings ascribed to such terms in the Merger Agreement.

If in fact the undersigned were an affiliate under the Securities Act, the undersigned’s ability to sell, assign or transfer the Constellation Common Stock received by the undersigned in exchange for any shares of FPL Group Common Stock pursuant to the Merger may be restricted unless such transaction is registered under the Securities Act or an exemption from such registration is available. The undersigned understands that such exemptions are limited and the undersigned has obtained or will obtain advice of counsel as to the nature and conditions of such exemptions, including information with respect to the applicability to the sale of such securities of Rules 144 and 145(d) promulgated under the Securities Act. The undersigned understands that Constellation will not be required to maintain the effectiveness of any registration statement under the Securities Act for the purposes of resale of Constellation Common Stock by the undersigned.

The undersigned hereby represents to and covenants with Constellation that the undersigned will not sell, assign or transfer any of the Constellation Common Stock received by the undersigned in exchange for shares of FPL Group Common Stock pursuant to the Merger except (i) pursuant to an effective registration statement under the Securities Act, (ii) in conformity with the volume and other limitations of Rule 145 or (iii) in a transaction which, in the opinion of counsel reasonably satisfactory to Constellation, or as described in a “no-action” or interpretive letter from the Staff of the SEC, is not required to be registered under the Securities Act.

In the event of a sale or other disposition by the undersigned pursuant to Rule 145 of Constellation Common Stock received by the undersigned in the Merger, the undersigned will supply Constellation with evidence of compliance with such Rule, in the form of a letter in the form of Annex I hereto or the opinion of counsel or no-action letter referred to above. The undersigned understands that Constellation may instruct its transfer agent to withhold the transfer of any Constellation Common Stock disposed of by the undersigned, but that (provided such transfer is not prohibited by any other provision of this letter agreement) upon receipt of such evidence of compliance, Constellation shall cause the transfer agent to effectuate the transfer of the Constellation Common Stock sold as indicated in such letter.

Constellation covenants that it will take all such actions as may be reasonably available to it to permit the sale or other disposition of the shares of Constellation Common Stock by the undersigned under Rule 145 in accordance with the terms thereof.

The undersigned acknowledges and agrees that the legend set forth below will be placed on certificates representing the shares of Constellation Common Stock received by the undersigned in connection with the

Merger or held by a transferee thereof, which legend will be removed by delivery of substitute certificates (i) if the undersigned provides evidence of compliance with Rule 145 to Constellation, in the form of a letter in the form of Annex I hereto, or (ii) upon receipt of an opinion in form and substance reasonably satisfactory to Constellation from counsel reasonably satisfactory to Constellation to the effect that such legend is no longer required for purposes of the Securities Act.

There will be placed on the certificates for Constellation Common Stock issued to the undersigned pursuant to the Merger, or any substitutions therefor, a legend stating in substance:

“The shares represented by this certificate were issued pursuant to a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares may not be sold, pledged or otherwise transferred except in accordance with Rule 145 promulgated under the Securities Act of 1933, pursuant to a Registration Statement under the Securities Act of 1933 or in accordance with an exemption from the registration requirements of the Securities Act of 1933.”

The undersigned acknowledges that (i) the undersigned has carefully read this letter and understands the requirements hereof and the limitations imposed upon the distribution, sale, transfer or other disposition of Constellation Common Stock and (ii) the receipt by Constellation of this letter is an inducement and a condition to Constellation’s obligations to consummate the Merger.

Execution of this letter should not be considered an admission on the part of the undersigned that the undersigned is an “affiliate” of the Company as described in the first paragraph of this letter, or as a waiver of any rights the undersigned may have to object to any claim that the undersigned is such an affiliate on or after the date of this letter.

Very truly yours,

Board of Directors

Constellation Energy Group Inc.

750 E. Pratt Street

Baltimore, MD 21202

Members of the Board:

We understand that Constellation Energy Group Inc. (“Constellation” or the “Company”), FPL Group, Inc. (“FPL”) and CF Merger Corporation, a wholly owned subsidiary of Constellation (“Merger Sub”), have entered into an Agreement and Plan of Merger, substantially in the form of the draft dated December 18, 2005 (the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into FPL (the “Merger”), with FPL as the surviving corporation. Immediately prior to and as a condition to the Merger, each issued and outstanding share of common stock, no par value per share, of Constellation (the “Constellation Common Stock”) will be divided into 1.444 shares of Constellation Common Stock (the “Stock Split”). Subject to the prior effectiveness of the Stock Split and pursuant to the Merger, each outstanding share of common stock, par value of $0.01 per share, of FPL (the “FPL Common Stock”), other than shares held in treasury or held by Constellation, shall be converted into the right to receive one share (the “Exchange Ratio”) of Constellation Common Stock. The terms and conditions of the Merger and the Stock Split are more fully set forth in the Merger Agreement and certain related documents.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the Merger Agreement, assuming the prior effectiveness of the Stock Split, is fair from a financial point of view to holders of shares of Constellation Common Stock.

For purposes of the opinion set forth herein, we have:

reviewed certain publicly-available financial statements and other business and financial information of the Company and FPL, respectively;

ii)

reviewed certain internal financial statements and other financial and operating data concerning the Company and FPL, prepared by the managements of the Company and FPL, respectively;

iii)

reviewed certain financial projections prepared by management of the Company and FPL;

iv)

discussed the past and current operations and financial condition and the prospects of the Company and FPL with senior executives of the Company and FPL, respectively;

reviewed the pro forma impact of the Merger on various Constellation financial metrics;

vi)

reviewed information relating to certain strategic, financial and operational benefits anticipated from the Merger prepared by the managements of the Company and FPL with senior executives of the Company and FPL, respectively;

vii)

discussed the strategic rationale for the Merger with senior executives of the Company and FPL;

viii)

reviewed the reported prices and trading activity for the Constellation Common Stock and the FPL Common Stock;

ix)

compared the financial performance of the Company and FPL and the prices and trading activity of the Constellation Common Stock and the FPL Common Stock with that of certain other comparable publicly-traded companies and their securities;

reviewed the financial terms, to the extent publicly available, of certain comparable acquisition transactions;

xi)

participated in discussions and negotiations among representatives of the Company and FPL and their financial and legal advisors;

xii)

reviewed the Merger Agreement and certain related documents; and

xiii)

considered such other factors and performed such other analyses as we have deemed appropriate.

B-1

We have assumed and relied upon without independent verification the accuracy and completeness of the information supplied or otherwise made available to us by the Company and FPL for the purposes of this opinion. With respect to the financial projections, including information relating to certain strategic, financial and operational benefits anticipated from the Merger, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of the Company and FPL. We have also relied on the assessments of senior management of Constellation and FPL of the strategic rationale for the Merger. We have assumed that the Stock Split will occur on the terms set forth in the Merger Agreement, including, among other things, the timing thereof. In addition, we have assumed that the Merger and the other transactions contemplated in the Merger Agreement will be consummated in accordance with the terms set forth in the Merger Agreement, including, among other things, that the Merger will be treated as a tax-free reorganization, pursuant to the Internal Revenue Code of 1986, as amended. We have assumed that in connection with the receipt of all necessary regulatory approvals for the proposed Merger, no restrictions would be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed Merger. We have not made any independent valuation or appraisal of the assets or liabilities of the Company or of FPL, nor have we been furnished with any such appraisals. We are not legal, regulatory or tax experts and have relied upon the assessments of the Company, after receiving advice from its other advisors, with respect to such issues. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof.

In arriving at our opinion, we were not authorized to solicit, and did not solicit, interest from any party with respect to an acquisition or business combination involving the Company or any of its assets.

We have acted as financial advisor to the Board of Directors of the Company in connection with this transaction and will receive a fee for our services, a significant portion of which is subject to the consummation of the Merger. In the ordinary course of our securities, currency and commodities trading, investment management or brokerage activities, Morgan Stanley & Co. Incorporated (“Morgan Stanley”) or its affiliates may actively trade the securities or loans of Constellation or FPL, or any currency or commodity related to Constellation or FPL for our own accounts, for the accounts of investment funds or other accounts under the management of Morgan Stanley or its affiliates and for the accounts of customers, and, accordingly may at any time hold a long or short position in such securities, loans, currencies or commodity. In addition, we are a participant in certain of the credit facilities of Constellation and FPL. In the past, Morgan Stanley and its affiliates have provided financial advisory and financing services for the Company and FPL and have received fees for the rendering of these services. We also may or may in the future seek to provide financial advice or financing services to Constellation and FPL and may receive fees for such services.

It is understood that this letter is for the information of the Board of Directors of the Company to assist it in evaluating the Merger and may not be used for any other purpose without our prior written consent, except that a copy of this opinion may be included in its entirety in any filing required to be made by the Company in respect of the Merger with the Securities and Exchange Commission. In addition, this opinion does not in any manner address the prices at which the Constellation Common Stock will trade following consummation of the Merger or at any other time, and Morgan Stanley expresses no opinion or recommendation as to how the shareholders of the Company should vote at the shareholders’ meeting held in connection with the Merger.

Based on and subject to the foregoing, we are of the opinion on the date hereof that the Exchange Ratio pursuant to the Merger Agreement, assuming the prior effectiveness of the Stock Split, is fair from a financial point of view to holders of Constellation Common Stock.


Very truly yours,

You have requested our opinion as to the fairness from a financial point of view to the holders of the outstanding shares of the common stock, no par value (the “Company Common Stock”), of Constellation Energy Group, Inc.

(“FPL”) pursuant to the Agreement and Plan of Merger, dated as of December 18, 2005 (the “Agreement”), among FPL Group, Inc.

Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We expect to receive fees for our services in connection with the transaction contemplated by the Agreement (the “Transaction”), all of which are payable upon the delivery of this opinion, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. We have been engaged solely for the purpose of undertaking a study to enable us to render our opinion as to the fairness from a financial point of view of the Exchange Ratio pursuant to the Agreement to the holders of the Company Common Stock and did not participate in the negotiations leading to the Transaction. We have provided certain investment banking and other services to the Company from time to time, including having extended an unfunded loan commitment (aggregate principal amount $155,000,000) to the Company in November 2005. We also may provide investment banking services to the Company and FPL in the future. In connection with the above-described investment banking and other services we have received, and may receive, compensation.

In addition to the foregoing, we note that Goldman Sachs Power LLC, an affiliate of Goldman, Sachs & Co. (“Goldman Sachs Power”), is party to an Amended and Restated Software Development and License Agreement, dated as of October 25, 2001 (the “Amended License Agreement”), with Constellation Power Source Inc., a subsidiary of the Company (“CPS”). The Amended License Agreement was entered into in connection and contemporaneously with the termination of certain business arrangements between Goldman Sachs Power and certain of its affiliates, on the one hand, and the Company and CPS, on the other hand. Goldman Sachs Power has advised CPS that the Amended License Agreement would remain in effect between the parties following the completion of the Transaction.

L.P. v. Florida Power & Light Company (pending in the U.S. District Court for the Middle District of Florida) and Cedar Bay Generating Company, Limited Partnership v. Florida Power & Light Company (pending in the Fourth Judicial Circuit Court, Duval County Florida).

Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, FPL and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and FPL for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and FPL for the five fiscal years ended December 31, 2004; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and FPL; certain other communications from the Company and FPL to their respective stockholders; certain internal financial analyses and forecasts for FPL prepared by the management of FPL; and certain internal financial analyses and forecasts for the Company and for FPL prepared by the management of the Company (collectively, the “Forecasts”), including certain cost savings and operating synergies projected by the managements of the Company and FPL to result from the Transaction. We also have held discussions with members of the senior managements of the Company and FPL regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of their respective companies. In addition, we have reviewed the reported price and trading activity for the Company Common Stock and the FPL Common Stock, compared certain financial and stock market information for the Company and FPL with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the utilities industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the Forecasts have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company and FPL, as the case may be. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or FPL or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We also have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction contemplated by the Agreement will be obtained without any adverse effect on the Company or FPL or on the expected benefits of the Transaction in any way meaningful to our analysis.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction nor are we expressing any opinion as to the prices at which the Company Common Stock or the FPL Common Stock will trade at any time. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of the Company Common Stock should vote with respect to the Transaction.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio, assuming the prior effectiveness of the Stock Split, pursuant to the Agreement is fair from a financial point of view to the holders of the Company Common Stock.

Very truly yours,

Board of Directors FPL Group, Inc.

P.O. Box 14000

Juno Beach, FL 33408-0420

Members of the Board of Directors:

Constellation Energy Group, Inc. (“Constellation”), FPL Group, Inc. (“FPL”) and CF Merger Corporation, a wholly owned subsidiary of Constellation (“Merger Sub”), propose to enter into an Agreement and Plan of Merger dated as of December 18, 2005 (the “Agreement”) pursuant to which Merger Sub will merge with and into FPL (the “Merger”) in which each outstanding share of common stock, par value $.01 per share, of FPL (“FPL Common Stock”), other than shares of FPL Common Stock owned by FPL or Constellation, will be converted into the right to receive one fully paid and nonassessable share (the “Exchange Ratio”) of common stock, no par value per share, of Constellation (“Constellation Common Stock”), subject to the prior effectiveness of a stock split whereby (1) the number of authorized shares of Constellation Common Stock will be increased and (2) the Constellation Common Stock shall be divided such that, immediately prior to the Merger becoming effective under the Agreement, each issued and outstanding share of Constellation Common Stock shall be automatically reclassified and converted into (assuming the effectiveness of the Merger) 1.444 fully paid and nonassessable shares of Constellation Common Stock.

You have asked us whether, in our opinion, the Exchange Ratio is fair from a financial point of view to the holders of FPL Common Stock.

In arriving at the opinion set forth below, we have, among other things:

(1)

Reviewed certain publicly available business and financial information relating to Constellation and FPL that we deemed to be relevant;

(2)

Reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of Constellation and FPL, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the Merger (the “Expected Synergies”) furnished to us by Constellation and FPL, respectively;

(3)

Conducted discussions with members of senior management and representatives of Constellation and FPL concerning the matters described in clauses 1 and 2 above, as well as their respective businesses and prospects before and after giving effect to the Merger and the Expected Synergies;

(4)

Reviewed the market prices and valuation multiples for Constellation Common Stock and FPL Common Stock and compared them with those of certain publicly traded companies that we deemed to be relevant;

(5)

Reviewed the results of operations of Constellation and FPL and compared them with those of certain publicly traded companies that we deemed to be relevant;

D-1

(6)

Compared the proposed financial terms of the Merger with the financial terms of certain other transactions that we deemed to be relevant;

(7)

Participated in certain discussions and negotiations among representatives of Constellation and FPL and their financial and legal advisors;

(8)

Reviewed the potential pro forma impact of the Merger;

(9)

Reviewed the Agreement dated December 18, 2005; and

(10)

Reviewed such other financial studies and analyses and took into account such other matters as we deemed necessary, including our assessment of general economic, market and monetary conditions.

In preparing our opinion, we have assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to us, discussed with or reviewed by or for us, or publicly available, and we have not assumed any responsibility for independently verifying such information or undertaken an independent evaluation or appraisal of any of the assets or liabilities of Constellation or FPL or been furnished with any such evaluation or appraisal, nor have we evaluated the solvency or fair value of Constellation or FPL under any state or federal laws relating to bankruptcy, insolvency or similar matters. In addition, we have not assumed any obligation to conduct any physical inspection of the properties or facilities of Constellation or FPL. With respect to the financial forecast information and the Expected Synergies furnished to or discussed with us by Constellation or FPL, we have assumed that they have been reasonably prepared and reflect the best currently available estimates and judgment of Constellation’s or FPL’s management as to the expected future financial performance of Constellation or FPL, as the case may be, and the Expected Synergies. We express no view as to such projections or information or the assumptions on which they are based. We have further assumed that the Merger will qualify as a tax-free reorganization for U.S. federal income tax purposes.

Our opinion is necessarily based upon market, economic and other conditions as they exist and can be evaluated on, and on the information made available to us as of, the date hereof. We have assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the Merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on the contemplated benefits of the Merger.

In connection with the preparation of this opinion, we have not been authorized by FPL or the Board of Directors to solicit, nor have we solicited, third party indications of interest for the acquisition of all or any part of FPL.

We are acting as financial advisor to FPL in connection with the Merger and will receive a fee from FPL for our services, a significant portion of which is contingent upon the consummation of the Merger. In addition, FPL has agreed to indemnify us for certain liabilities arising out of our engagement. We have, in the past, provided financial advisory and financing services to FPL and Constellation and/or its affiliates and may continue to do so and have received, and may receive, fees for the rendering of such services. In March 2004, we acted as lead underwriter with respect to a $275 million offering of Trust Originated Preferred Securities^SM by FPL Group Capital, a wholly owned subsidiary of FPL. In addition, in the ordinary course of our business, we may actively trade Constellation Common Stock and other securities of Constellation, as well as FPL Common Stock and other securities of FPL, for our own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

This opinion is for the use and benefit of the Board of Directors of FPL. Our opinion does not address the merits of the underlying decision by FPL to engage in the Merger and does not constitute a recommendation to any shareholder of FPL as to how such shareholder should vote on the proposed Merger or any matter related thereto. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of FPL, other than the holders of the FPL Common Stock. We are not expressing any opinion herein as to the prices at which FPL Common Stock will trade following the announcement of the Merger or at which Constellation Common Stock will trade following the announcement or consummation of the Merger.

D-2

On the basis of and subject to the foregoing, we are of the opinion that, as of the date hereof, the Exchange Ratio is fair from a financial point of view to the holders of FPL Common Stock.

P. O. Box 14000

Juno Beach, FL 33408-0420

Members of the Board:

We understand that FPL Group Inc. (the “Company”) and Constellation Energy Group, Inc. (“Constellation”) intend to enter into an Agreement and Plan of Merger dated as of December 18, 2005 (the “Agreement”) pursuant to which, among other things, CF Merger Corporation, a wholly-owned subsidiary of Constellation will be merged with and into the Company with the Company surviving the merger (the “Proposed Transaction”). We further understand that, upon the effectiveness of the Proposed Transaction, each issued and then outstanding share of common stock of the Company (“Company Common Stock”), other than shares of Company Common Stock owned by the Company or Constellation, will be converted into the right to receive one (1) share (the “Exchange Ratio”) of common stock of Constellation (“Constellation Common Stock”) subject to the prior division and conversion of each issued and then outstanding share of Constellation Common Stock into 1.444 shares of Constellation Common Stock (the “Stock Split”) that will take place immediately prior to the effective time of the Proposed Transaction. The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement.

We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the shareholders of the Company of the Exchange Ratio, assuming the prior effectiveness of the Stock Split, to be offered to the shareholders of the Company in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company’s underlying business decision to proceed with or effect the Proposed Transaction.

In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction; (2) publicly available information concerning the Company and Constellation that we believe to be relevant to our analysis, including each of their respective Annual Reports on Form 10-K for the fiscal year ended December 31, 2004, Quarterly Reports on Form 10-Q for the quarterly period ended September 30, 2005, and other relevant filings with the Securities and Exchange Commission; (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including financial projections of the Company and extensions of such financial projections, in each case, prepared by the Company’s management; (4) financial and operating information with respect to the business, operations and prospects of Constellation furnished to us by the Company, including financial projections of Constellation prepared by the managements of Constellation and the Company; (5) trading histories of Company Common Stock and of Constellation Common Stock from December 13, 2003 through December 13, 2005, and a comparison of each of their trading histories with each other and with those of other companies that we deemed relevant; (6) a comparison of the historical financial results and present financial condition of the Company and Constellation with each other and with those of other companies that we deemed relevant; (7) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other recent transactions that we deemed relevant; (8) the relative contributions of the Company and Constellation to the historical and future financial performance of the combined company on a pro forma basis; and (9) the potential pro forma impact of the Proposed Transaction on the future financial condition and financial performance of the Company, including the cost savings, operating synergies and strategic benefits expected to

result from the combination of the businesses of the Company and Constellation as estimated by the management of the Company (the “Expected Synergies”) and purchase accounting adjustments to the basis of Constellation for reporting purposes under generally accepted accounting principles in the United States as estimated by the management of the Company (the “Purchase Accounting Adjustments”). In addition, we have had discussions with the managements of the Company and Constellation concerning their respective businesses, operations, assets, liabilities, financial conditions and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate.

In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of the managements of the Company and Constellation that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company and Constellation, upon advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the managements of the Company and Constellation as to the future financial performance of the Company and Constellation, respectively, and that the Company and Constellation will perform substantially in accordance with such projections. We have assumed, upon the advice of the Company, that the positions in the trading book of the Constellation Energy Commodities Group have been accurately reflected in the financial statements of Constellation and the financial impact of such positions as reflected in the financial projections of Constellation will be realized substantially in accordance with such estimates and have relied upon such financial statements and projections in performing our analysis. With respect to the Expected Synergies and Purchase Accounting Adjustments, upon advice of the Company, we have assumed that the amount and timing of the Expected Synergies are reasonable and that the Expected Synergies will be realized and the Purchase Accounting Adjustments will be recorded, in each case substantially in accordance with such estimates, and we have relied on the Expected Synergies and the Purchase Accounting Adjustments in performing our analysis. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company or Constellation and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company or Constellation. We have further assumed, upon advice of the Company, that all material governmental, regulatory or other consents or approvals necessary for the consummation of the Proposed Transaction will be obtained within the constraints contemplated by the Agreement. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter.

In addition, we express no opinion as to the prices at which shares of (i) Company Common Stock or Constellation Common Stock will trade at any time following the announcement of the Proposed Transaction or (ii) Constellation Common Stock will trade at any time following the consummation of the Proposed Transaction.

Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Exchange Ratio, assuming the prior effectiveness of the Stock Split, to be offered to the shareholders of the Company in the Proposed Transaction is fair to the shareholders of the Company.

We have been engaged by the Company to act as advisor to the Board of Directors of the Company to render to the Board of Directors this opinion in connection with the Proposed Transaction, and will receive a fee upon delivery of this opinion. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for the

Company and Constellation in the past (including financings and advisory services) for which we have received customary fees and we expect to perform various investment banking services for the Company and Constellation in the future for which we expect to receive customary fees. In the ordinary course of our business, we actively trade in the debt and equity securities of the Company and Constellation for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.

This opinion is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction.

ARTICLE II

STOCKHOLDERS

Section 1.—Place of Meetings.

Meetings of stockholders of the Corporation shall be held at such places, either within or without the State of Maryland or the State of Florida, as may be fixed from time to time by the Board and stated in the notice of meeting or in a duly executed waiver of notice thereof. Special meetings of the stockholders may be held at such time as may be stated in the notice of meeting.

Section 2.—Annual Meetings.

The Annual Meeting of the stockholders for the election of Directors and for the transaction of general business shall be held on any date during the period of May 1 through May 31 as determined from year to year by the Board. The time and location of the meeting shall be determined by the Board. Failure to hold an Annual Meeting does not invalidate the Corporation’s existence or affect any otherwise valid corporate acts.

The Chief Executive Officer of the Corporation shall prepare, or cause to be prepared, an annual report containing a full and correct statement of the affairs of the Corporation, including a balance sheet and a financial statement of operations for the preceding fiscal year, which shall be submitted to the stockholders at or prior to the Annual Meeting.

Section 3.—Special Meetings.

Special meetings of the stockholders may be held, either within or without the State of Maryland or State of Florida, upon call by the Chairman of the Board, the Chief Executive Officer, the Secretary or a majority of the

G-1

Board whenever they deem expedient, or by the Secretary upon the written request of the holders of shares entitled to not less than a majority of all the votes entitled to be cast at such meeting. Such request of the stockholders shall state the purpose or purposes of the meeting and the matters proposed to be acted on and shall be delivered to the Secretary, who shall inform such stockholders of the reasonably estimated cost of preparing and mailing such notice of the meeting, and upon payment to the Corporation of such costs the Secretary shall give notice stating the purpose or purposes of the meeting to all stockholders entitled to vote at such meeting. The business at all special meetings shall be confined to that specifically named in the notice thereof given in accordance with this Section 3 of Article I.

Section 4.—Notice and Waiver; Organization of Meeting.

When stockholders are required or permitted to take any action at a meeting whether special or annual, written, printed or electronic notice of such meeting shall be given to each stockholder entitled to vote at the meeting and each other stockholder entitled to notice of the meeting, by or at the direction of the Chairman of the Board, the Chief Executive Officer, the Secretary, or the Officer or persons calling the meeting. The notice shall state the place, day, and hour of such meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called. The notice of any meeting shall be given, personally, by mail or electronically, or in any such other manner as may be permitted by law, not less than 10 or more than 90 days before the date of the meeting. If mailed, such notice shall be deemed to be given when deposited in the United States mail addressed to the stockholder at his or her address as it appears on the stock transfer books of the Corporation, with postage thereon prepaid.

Any notice given by the Corporation to a stockholder is effective if given by a single notice, in writing or by electronic transmission, to all stockholders who share an address if the Corporation gives notice, in writing or by electronic transmission, to the stockholder of its intent to give a single notice and the stockholder consents to receiving a single notice or fails to object in writing within 60 days after the Corporation gives notice to the stockholder of its intent to give a single notice. A stockholder may revoke consent given, whether affirmative or implied, by written notice to the Corporation. The notice shall state the time of the meeting, the place of the meeting, if any, and the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and may vote at the meeting and, if the meeting is a special meeting or notice of the purpose is required by statute, the purpose of the meeting. Notice is given to a stockholder when it is personally delivered to the stockholder, left at the stockholder’s residence or usual place of business, mailed to the stockholder at the stockholder’s address as it appears on the records of the Corporation or transmitted to the stockholder by an electronic transmission to any address or number of the stockholder at which the stockholder receives electronic transmissions. If the Corporation has received a request from a stockholder that notice not be sent by electronic transmission, the Corporation may not provide notice to the stockholder by electronic transmission. Notice given by electronic transmission shall be considered ineffective if the Corporation is unable to deliver two consecutive notices and the inability to deliver the notices becomes known to the Secretary, an Assistant Secretary, the transfer agent or other person responsible for giving the notice. The inadvertent failure to deliver any notice by electronic transmission does not invalidate any meeting or other action. An affidavit of the Secretary, the transfer agent or other agent of the Corporation that notice has been given by a form of electronic transmission, in the absence of actual fraud, shall be prima facie evidence of the facts stated in the affidavit.

When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken unless the adjournment is to a date more than 120 days after the original record date, or, if after the adjournment, a new record date is fixed for the adjourned meeting, in which circumstances a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting.

Notice of any meeting of stockholders may be waived before or after the meeting in writing or by electronic transmission by any stockholder entitled to notice of such meeting. Attendance at a meeting by any stockholder,

G-2

in person or by proxy, shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

Meetings of the stockholders may be presided over by the Chairman of the Board, the Chief Executive Officer, the President or any Vice President. The Secretary of the Corporation, if present, shall act as secretary of the meeting, unless some other person shall be elected by the stockholders at the meeting to act as secretary. An accurate record of the meeting shall be kept by the secretary thereof, and placed in the record books of the Corporation.

Section 5.—Order of Business.

(a) At any Annual Meeting, only such business shall be conducted as shall have been brought before the Annual Meeting (i) pursuant to the Corporation’s notice of meeting (or any supplement thereto), (ii) by or at the direction of the Board (or any duly authorized committee thereof) or (iii) by any stockholder who is a holder of record at the time of the giving of the notice provided for in Section 4 of this Article III, who is entitled to vote at the meeting and complies with the procedures set forth in this Section 5.

(b) For nominations or other business to be brought properly before an Annual Meeting by a stockholder, the stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation. To be timely, a stockholder’s notice must be delivered in person or by facsimile (to the number specified for such purpose in the most recent annual proxy statement filed by the Corporation with the Securities and Exchange Commission prior to the date of such notice) to, or sent by U.S. certified mail and received at the principal office of the Corporation by the Secretary of the Corporation not less than 90 days nor more than 120 days prior to the anniversary of the date on which notice of the prior year’s Annual Meeting was given to stockholders in accordance with Section 4 of this Article II; provided, however, that in the event that the date of the Annual Meeting is more than 30 days earlier or more than 60 days later than such anniversary date, notice by the stockholder to be timely must be so delivered or received not earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. In no event shall the public announcement of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of notice by a stockholder as described above. To be in proper written form, a stockholder’s notice to the Secretary shall set forth in writing as to each matter the stockholder proposes to bring before the Annual Meeting:

(i) as to each person whom the stockholder proposes to nominate for election or re-election as a Director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of Directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934 (the “Exchange Act”) or any applicable successor provisions thereto, including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected; and as to the stockholder giving the notice, the name and address, as they appear on the Corporation’s books, of the stockholder proposing such nomination and the class and number of shares of stock of the Corporation which are beneficially owned by the stockholder.

(ii) as to any other business that the stockholder proposes to bring before the Annual Meeting:

(A) a brief description of the business desired to be brought before the Annual Meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration) and the reasons for conducting such business at the Annual Meeting and in the event that such business includes a proposal to amend the By-Laws of the Corporation, the language of the proposed amendment;

(B) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business and the name and address of the beneficial owner, if any, on whose behalf the nomination or proposal is being made;

G-3

(D) any material interest of the stockholder in such nomination or other business;

(E) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such Annual Meeting on the matter proposed and intends to appear in person or by proxy at such Annual Meeting to propose such nomination or other business; and

(F) if the stockholder intends to solicit proxies in support of such stockholder’s proposal, a representation to that effect.

(c) Notwithstanding anything in paragraph (b) above to the contrary, in the event that the number of Directors to be elected to the Board at an Annual Meeting of the stockholders is increased in accordance with Article III, Section 2 and there is no public announcement naming all of the nominees for Directors or specifying the size of the increased Board made by the Corporation at least 90 days prior to the first anniversary of the date of the immediately preceding Annual Meeting, a stockholder’s notice required by this Section 5 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered in person or by facsimile (to the number specified for such purpose in the most recent annual proxy statement filed by the Corporation with the Securities and Exchange Commission prior to the date of such notice) to, or sent by U.S. certified mail and received at the principal offices of the Corporation by the Secretary of the Corporation not later than the close of business on the 10th day following the day on which the public announcement naming all of the nominees for Directors or specifying the size of the increased Board made by the Corporation is first made by the Corporation.

(d) Nominations of persons for election to the Board may be made at a special meeting of stockholders at which Directors are to be elected pursuant to the Corporation’s notice of meeting (i) by or at the direction of the Board (or any duly authorized committee thereof) or (ii) provided that the Board has determined that Directors shall be elected at such meeting, by any stockholder of the Corporation who is a holder of record at the time of the giving of notice provided for in Section 4 of this Article III, who is entitled to vote at the meeting for the election of Directors and who complies with the procedures set forth in this Section 5. In the event a special meeting of stockholders is properly called for the purpose of electing one or more Directors to the Board, any such stockholder may nominate a person or persons (as the case may be), for election to such position(s) as specified in the Corporation’s notice of meeting, if the stockholder has given timely notice thereof in proper written form to the Secretary of the Corporation. To be timely, a stockholder’s notice must be delivered in person or by facsimile (to the number specified for such purpose in the most recent annual proxy statement filed by the Corporation with the Securities and Exchange Commission prior to the date of such notice) to, or sent by U.S. certified mail and received at the principal offices of the Corporation by the Secretary of the Corporation not earlier than the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which public announcement of the date of such special meeting is first made. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a new time period (or extend any time period) for the giving of notice by a stockholder as described above. To be in proper written form, such notice must meet the requirements of paragraph (b) above applicable to nominations of persons for election to the Board.

(e) The notice requirements set forth in this Section 5 shall be deemed satisfied by a stockholder if the stockholder has notified the Corporation of his or her intention to make a nomination or present a proposal at the applicable meeting of stockholders and such stockholder’s nominee or proposal has been included in a proxy statement that has been prepared by management of the Corporation to solicit proxies for such meeting; provided, however, that if such stockholder does not appear or send a qualified representative to present such nominee or proposal at such meeting, the Corporation need not present such nominee or proposal for a vote at such meeting notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 5, to be considered a qualified representative of

G-4

the stockholder, a person must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to the Secretary of the Corporation to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of such writing or electronic transmission, at the meeting of stockholders. The Corporation may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a Director of the Corporation (including any applicable requirements regarding the independence of Directors).

(f) Notwithstanding anything in these By-Laws to the contrary, only such persons who are nominated in accordance with this Section 5 or Section 10 of Article III or are chosen to fill any vacancy occurring in the Board in accordance with Section 3 or Section 10 of Article III shall be eligible to serve as Directors of the Corporation and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with this Section 5. The Chairman of a meeting shall refuse to permit any business to be brought before the meeting which fails to comply with the foregoing or if a stockholder solicits proxies in support of such stockholder’s nominee or proposal without such stockholder having made the representation required by clause (E) of paragraph (b)(ii) above.

(g) Notwithstanding the foregoing provisions of this Section, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder, and all applicable rules and requirements of the New York Stock Exchange (the “NYSE”) or, if the Corporation’s shares are not listed on the NYSE, the applicable rules and requirements of the primary securities exchange or quotation system on which the Corporation’s shares are listed or quoted, in each case with respect to the matters set forth in this Section. Nothing in this Section shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to applicable rules and regulations promulgated under the Exchange Act.

(h) For purposes of this Section 5, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Services, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

Section 6.—Quorum.

At any meeting of the stockholders the presence in person or by proxy of stockholders entitled to cast a majority of the votes thereat shall constitute a quorum for the transaction of business. If a specified item of business is required to be voted on by a class or series of shares, the presence in person or by proxy of stockholders entitled to cast a majority of the votes of such class or series thereat shall constitute a quorum for the transaction of business.

When a quorum is once present to organize a meeting, it is not broken by the subsequent withdrawal of any stockholders.

The stockholders present, although less than a quorum, may adjourn the meeting to another time or place; provided that notice of such adjourned meeting is given in accordance with the provisions of Section 4 of this Article II.

Section 7.—Voting; Proxies.

At all meetings of the stockholders each stockholder shall be entitled to one vote for each share of Common Stock standing in his or her name and, when the Preferred Stock is entitled to vote, such number of votes as shall be provided in the Charter of the Corporation for each share of Preferred Stock standing in his or her name, and the votes shall be cast by stockholders in person or by lawful proxy. However, no proxy shall be voted 11 months after the date thereof, unless the proxy provides for a longer period.

G-5

Section 8.—Control Shares.

Notwithstanding any other provision of the Charter of the Corporation or these By-Laws, Title 3, Subtitle 7 of the Maryland General Corporation Law (or any successor statute) shall not apply to any acquisition by any person of shares of stock of the Corporation. This section may be repealed, in whole or in part, at any time, whether before or after an acquisition of control shares and, upon such repeal, such statute may, to the extent provided by any successor by-law, apply to any prior or subsequent control share acquisition.

Section 9.—Method of Voting.

All elections and all other questions shall be decided by a majority of the votes cast at a meeting at which a quorum is present, except (a) if a greater vote is expressly required by the general laws of the State of Maryland, the Charter or these By-laws, or by action of the Board from time to time, in which case such express provision shall apply, or (b) in an election of Directors in which the number of nominees exceeds the number of Directors to be elected (referred to herein as a “contested election”), in which case Directors shall be elected by a plurality of the votes cast.

Section 10.—Ownership of its Own Stock.

Shares of capital stock of the Corporation held by either (i) the Corporation or (ii) another corporation, if a majority of the shares entitled to vote in the election of Directors of such other corporation is held, directly or indirectly, by the Corporation (a “Controlled Corporation”), shall neither be entitled to vote nor be counted for quorum purposes. Nothing in this Section 10 shall be construed as limiting the right of the Corporation or any Controlled Corporation to vote stock of the Corporation held by it in a fiduciary capacity.

Section 11.—Inspectors.

The Board, in advance of any meeting, may, but need not, appoint one or more individual inspectors or one or more entities that designate individuals as inspectors to act at the meeting or any adjournment thereof. If an inspector or inspectors are not appointed, the person presiding at the meeting may, but need not, appoint one or more inspectors. In case any person who may be appointed as an inspector fails to appear or act, the vacancy may be filled by appointment made by the Board in advance of the meeting or at the meeting by the chairman of the meeting. The inspectors, if any, shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. Each such report shall be in writing and signed by him or her or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

Section 12.—Record Date for Stockholders; Closing of Transfer Books.

The Board may fix, in advance, a date as the record for the determination of the stockholders entitled to notice of, or to vote at, any meeting of stockholders, or entitled to receive payment of any dividend, or entitled to the allotment of any rights, or for any other proper purpose. Such date in any case shall not be more than 90 days (and in the case of a meeting of stockholders not less than 10 days) prior to the date on which the particular action requiring such determination of stockholders is to be taken (other than in the case of an adjournment). Only stockholders of record on such date shall be entitled to notice of or to vote at such meeting or to receive such dividends or rights, as the case may be. In lieu of fixing a record date the Board may close the stock transfer books of the Corporation for a period not exceeding 20 nor less than 10 days preceding the date of any meeting of stockholders or not exceeding 20 days preceding any other of the above mentioned events. When a

G-6

determination of the stockholders entitled to vote at any meeting of stockholders has been made as provided in this Section 12 of Article II, such determination shall apply to any adjournment thereof, unless the Board fixes a new record date for the adjourned meeting.

ARTICLE III

BOARD OF DIRECTORS AND COMMITTEES

Section 1.—Powers of Directors.

The business and affairs of the Corporation shall be managed under the direction of the Board which shall have and may exercise all the powers of the Corporation, except such as are expressly conferred upon or reserved by the stockholders by law, by Charter, or by these By-Laws. Except as otherwise provided herein, the Board shall appoint the Officers for the conduct of the business of the Corporation, determine their duties and responsibilities.

Section 2.—Number of Directors.

The Corporation shall have at least seven (7) Directors; provided that the Board, and only the Board, may alter the number of Directors from time to time so long as such number does not exceed 16. No decrease in the number of Directors constituting the Board shall shorten the term of any incumbent Director. At each Annual Meeting, the stockholders shall elect Directors to hold office until the next Annual Meeting and until their successors are elected and qualified.

Section 3.—Vacancies.

If for any reason any or all of the Directors cease to be Directors, such event shall not terminate the Corporation or affect these By-Laws or the powers of the remaining Directors hereunder (even if fewer than seven Directors remain). Subject to Section 10 of this Article III, except as may be provided by the Board after the Second Anniversary (as defined in Section 10 of this Article III) in setting the terms of any class or series of preferred stock, any vacancy on the Board may be filled only by a majority of the remaining Directors, even if the remaining Directors do not constitute a quorum. Any Director elected to fill a vacancy shall serve until a successor is elected and qualified at the next Annual Meeting.

Section 4.—Resignation and Retirement.

Any Director of the Corporation may resign at any time by giving written notice to the Corporation. Such resignation shall take effect at the time specified therein, if any, or if no time is specified therein, then upon receipt of such notice by the Corporation; and, unless otherwise provided therein, the acceptance of such resignation shall not be necessary to make it effective. No person who shall have attained the age of 72 years by the date of election shall be eligible for election as a Director of the Corporation, and no Director who shall have attained the age of 70 years by the date of election shall be eligible for election as Chairman of the Board; provided, however, that these limitations shall not be applied in a manner which would cause the involuntary retirement of an employee of the Corporation.

Section 5.—Meetings of the Board.

(a)

A regular meeting of the Board shall be held without notice at the location of and immediately after the Annual Meeting of stockholders or any special meeting of the stockholders at which the Board is elected, and thereafter regular meetings of the Board shall be held on such dates during the year as may be designated from time to time by the Board. Meetings of the Board may be held in the Baltimore, Maryland vicinity or in the Juno Beach, Florida vicinity or elsewhere, as ordered by the Board. Of all such meetings (except the regular meeting held immediately after the election of Directors) the

G-7

Secretary shall give notice to each Director personally or by telephone, facsimile or electronically directed to, or by written notice deposited in the mails or with a reputable overnight carrier addressed to, his or her residence or business address at least 48 hours before such meeting.

(b)

Special meetings may be held at any time or place upon the call of any two Directors or the Chairman of the Board or the Chief Executive Officer by notices as above. In the event all of the Directors in office waive notice of any meeting in writing at, before or after the meeting, the meeting may be held without the aforesaid advance notices.

(c)

Except as otherwise provided by the Charter of the Corporation, neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board need be specified in the notice or waiver of notice of such meeting.

(d)

A majority of the Directors present, whether or not a quorum exists, may adjourn any meeting of the Board to another time and place. Notice of such adjourned meeting shall be given to the Directors who were not present at the time of the adjournment and, unless the time and place of the adjourned meeting are announced at the time of the adjournment, to the other Directors.

(e)

Any action required to be taken at a meeting of the Directors or any action which may be taken at a meeting of the Directors or a committee thereof, may be taken without a meeting if a consent in writing, setting forth the action so to be taken, signed by all of the Directors or all the members of the committee, as the case may be, is filed in the minutes of the proceedings of the Board or of the committee. Such consent shall have the same effect as a unanimous vote.

Section 6.—Attendance at Board Meetings.

The Chairman shall preside at all meetings of the Board, or, in his or her absence, the Chief Executive Officer shall preside. If at any meeting none of the foregoing persons is present, the Directors present shall designate one of their number to preside at such meeting.

Section 7.—Telephone Meetings Permitted.

Members of the Board, or any committee, may participate in a meeting thereof by means of conference telephone or similar communications equipment in which all persons participating in the meeting can hear each other, and such participation shall constitute presence in person at such meeting.

Section 8.—Quorum.

A majority of the Directors in office shall constitute a quorum of the Board for the transaction of business. The act of the majority of the Directors present at a meeting at which a quorum is present shall be the act of the Board. If a quorum is not present at any meeting, a majority of the Directors present may adjourn to any time and place they may see fit.

Section 9.—Committees.

(a) The Board is authorized, by resolution adopted by a majority (excluding any Directors who abstain, or recuse themselves, from the vote on such matter due to a lack of independence with respect to the subject matter to be addressed by the relevant committee or other similar conflict) of the members of the entire Board (excluding any Directors who abstain or recuse themselves in accordance with the previous parenthetical), to appoint from among its members, one or more committees as it may, from time to time, deem advisable and to delegate to such committee or committees any of the powers of the Board that it may lawfully delegate. The audit committee shall have, at a minimum, the number of members required by applicable law or stock exchange listing standards. All vacancies in said committees shall be filled by action of a majority (excluding any Directors who abstain, or recuse themselves, from the vote on such matter due to a lack of independence with respect to the subject matter to be addressed by the relevant committee or other similar conflict) of the members of the entire Board (excluding any Directors who abstain or recuse

G-8

themselves in accordance with the previous parenthetical), subject to the restrictions on membership contained in this Section 9. The purposes and authority of each committee shall be as set forth in applicable law, board resolution adopted in accordance with this Section 9 or committee charter.

(b) The Board, by resolution adopted in accordance with this Section 9, shall designate a chairperson for each standing committee it establishes, who shall preside at all meetings of such standing committee and who shall have such additional duties as shall from time to time be designated by the Board. Any special committee shall determine at the first meeting of such committee the procedures for designating a chairperson of such committee, who shall preside at all meetings of such committee, and for determining the additional duties of such chairperson from time to time.

(c) The Board, by resolution adopted in accordance with this Section 9, may designate one or more Directors as alternate members of any such committee, who may act in the place and stead of any absent member or members at any meeting of such committee.

Notwithstanding anything to the contrary in this Article III or elsewhere in these By-Laws:

(a) As of the Effective Time and until at least the second anniversary of the Effective Time (the “Second Anniversary”), the number of Directors that shall constitute the entire Board shall be fifteen (15). As of the Effective Time, the Board shall consist of six (6) Constellation Designated Directors (as defined below) and nine (9) FPL Group Designated Directors (as defined below).

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.

Indemnification of Directors and Officers

The following description of indemnification allowed under Maryland statutory law is a summary rather than a complete description. Reference is made to Section 2-418 of the Corporations and Associations Article of the Annotated Code of Maryland, which is incorporated herein by reference, and the following summary is qualified in its entirety by such reference.

By a Maryland statute, a Maryland corporation may indemnify any director who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (“Proceeding”) by reason of the fact that he or she is a present or former director of the corporation and any person who, while a director of the corporation, is or was serving at the request of the corporation as a director, officer, partner, trustee, employee, or agent of another corporation, partnership, joint venture, trust, other enterprise, or employee benefit plan (“Director”). Such indemnification may be against judgments, penalties, fines, settlements and reasonable expenses actually incurred by him or her in connection with the Proceeding unless it is proven that (a) the act or omission of the Director was material to the matter giving rise to the Proceeding and (i) was committed in bad faith, or (ii) was the result of active and deliberate dishonesty; or (b) the Director actually received an improper personal benefit in money, property, or services; or (c) in the case of any criminal proceeding, the Director had reasonable cause to believe his or her act or omission was unlawful. However, the corporation may not indemnify any Director in connection with a Proceeding by or in the right of the corporation if the Director has been adjudged to be liable to the corporation. A Director or officer who has been successful in the defense of any Proceeding described above shall be indemnified against reasonable expenses incurred in connection with the Proceeding. The corporation may not indemnify a Director in respect of any Proceeding charging improper personal benefits to the Director in which the Director was adjudged to be liable on the basis that personal benefit was improperly received. The corporation may not indemnify a director or advance expenses for a proceeding brought by the director against the corporation except if the proceeding is brought to enforce indemnification by the corporation or if the corporation’s charter or by-laws, a board resolution or contract provides otherwise. Notwithstanding the above provisions, a court of appropriate jurisdiction, upon application of the Director, may order indemnification if it determines that in view of all the relevant circumstances, the Director is fairly and reasonably entitled to indemnification; however, indemnification with respect to any Proceeding by or in the right of the corporation or in which liability was adjudged on the basis that personal benefit was improperly received shall be limited to expenses. A corporation may advance reasonable expenses to a Director under certain circumstances upon receipt by the corporation of a written undertaking by or on behalf of such Director to repay the amount if it shall ultimately be determined that the standard of conduct necessary for indemnification by the corporation has not been met and a written affirmation by the Director of the Director’s good faith belief that the standard of conduct necessary for indemnification by the corporation as authorized in Section 2-418 has been met.

A corporation may indemnify and advance expenses to an officer of the corporation to the same extent that it may indemnify Directors under the statute.

The indemnification and advancement of expenses provided by statute is not exclusive of any other rights, by indemnification or otherwise, to which a Director or officer may be entitled under the charter, by-laws, a resolution of stockholders or directors, an agreement or otherwise.

A corporation may purchase and maintain insurance on behalf of any person who is or was a Director or officer, whether or not the corporation would have the power to indemnify a Director or officer against liability under the provision of this section of Maryland law. Further, a corporation may provide similar protection, including a trust fund, letter of credit or surety bond, not inconsistent with the statute.

II-1

Article Eighth of Constellation’s charter reads as follows:

“(a)(i) The Corporation shall indemnify

(B) other employees and agents, to such extent as shall be authorized by the Board of Directors or the Corporation’s by-laws and be permitted by law.

(ii) The foregoing rights of indemnification shall not be exclusive of any other rights to which those seeking indemnification may be entitled.

Article V of Constellation’s by-laws reads as follows:

“The Corporation shall indemnify all Directors, Officers and employees to the fullest extent permitted by the general laws of the State of Maryland, as in effect from time to time, and, to the extent permitted thereby, shall pay or reimburse expenses in advance of final disposition of a proceeding. The Corporation will follow the procedures required by applicable law in determining persons eligible for indemnification and in making indemnification payments and advances.

The indemnification and advance of expenses provided by the Charter and these By-laws shall not be deemed exclusive of any other rights to which a person seeking indemnification or advance of expenses may be entitled under any law (common or statutory), or any agreement, vote of stockholders or disinterested Directors or other provision that is consistent with law, both as to action in his or her official capacity and as to action in another capacity while holding office or while employed or acting as agent for the corporation, shall continue in respect of all events occurring while a person was a Director or Officer after such person has ceased to be a Director or Officer, and shall inure to the benefits of the estate, heirs, executors and administrators of such person. All rights to indemnification and advance of expenses under the Charter of the Corporation and hereunder shall be deemed to be a contract between the Corporation and each Director or Officer of the Corporation who serves or served in such capacity at any time while this by-law is in effect. Nothing herein shall prevent the amendment of this by-law, provided that no such amendment shall diminish the rights of any person hereunder with respect to events occurring or claims made before its adoption or as to claims made after its adoption in respect of events occurring before its adoption. Any repeal or modification of this by-law shall not in any way diminish any rights to indemnification or advance of expenses of such Director or Officer or the obligations of the Corporation arising hereunder with respect to events occurring, or claims made, while this by-law or any provision hereof is in force.

II-2

The directors and officers of Constellation are covered by insurance indemnifying them against certain liabilities which might be incurred by them in their capacities as such, including certain liabilities arising under the Securities Act of 1933. The premium for this insurance is paid by Constellation.

(e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

(f) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
