          1.3  Transfer of Nuclear Generating Plants to FE Nuclear.
               ---------------------------------------------------

          The Utility Subsidiaries own, as tenants in common, interests in the
following nuclear generating plants:

Perry                North Perry Village, OH      1,260     OES Nuclear 17.42%
                                                            Penn Power 5.245%
                                                            Toledo Edison 19.91%
                                                            Cleveland Electric 44.85%
----------------------------------------------------------------------------------------



          The Utility Subsidiaries propose to sell or otherwise transfer their
respective ownership interests in the nuclear plants to FE Nuclear by means of
the following transactions, all of which will be carried out concurrently:/3/

          Transfer of Nuclear Plants by Penn Power. Initially, pursuant to the
terms of a Subscription and Capital Contribution Agreement ("Penn Power
Contribution Agreement"), filed herewith as Exhibit B-1, Penn Power will acquire
100 shares of common stock of FE Nuclear in consideration for Penn Power's
contribution to FE Nuclear of its undivided interests in the two Beaver Valley
units and Beaver Valley common facilities and its undivided interest in Perry
Unit 1, together with associated decommissioning funds. In connection with such
contribution, FE Nuclear will assume Penn Power's obligations in respect of $64
million aggregate principal amount of pollution control revenue bonds ("PCRBs")
and certain other liabilities associated with the transferred units. The parties
to the Penn Power Contribution Agreement have agreed that the value of the
contributed assets will be the net book value thereof as of the end of the
fiscal quarter immediately preceding the closing. Simultaneously, Penn Power
will receive from FE Nuclear a promissory note in the form of Exhibit B-5 hereto
("FE Nuclear Note") in respect of the book value of certain related assets,
including construction work in progress, nuclear fuel, inventories and spare
parts and accounts receivable, determined as of the end of the quarter
immediately preceding the closing. The FE Nuclear Note will bear interest at a
rate equal to Penn Power's weighted average cost of long-term debt, determined
as shown in Exhibit I hereto, will mature 20 years after its date of issuance,
and will be prepayable at any time, in whole or in part, by FE Nuclear.

          Following the contribution to FE Nuclear, Penn Power will distribute
the stock of FE Nuclear as a dividend to its parent, Ohio Edison, such that FE
Nuclear will become, momentarily, a direct wholly-owned subsidiary of Ohio
Edison. If the transactions described in the previous paragraph had occurred on
March 31, 2005, Penn Power's cost basis for the stock of FE Nuclear would have
been equal to the net book value of the transferred interests in the Beaver
Valley and Perry units and associated assets (approximately $542 million), less
the PCRB obligations ($64 million) and agreed upon value of other liabilities
assumed by FE Nuclear (approximately $401 million), and the distribution of the
stock of FE Nuclear to Ohio Edison would have resulted in a charge to Penn
Power's retained earnings of $77 million.

----------
3     The Utility Subsidiaries do not propose to transfer to FE Nuclear their
      remaining percentage ownership interests in certain of the nuclear
      facilities that are currently subject to sale and leaseback arrangements
      with third parties.


                                       4



          Transfer of Nuclear Plants by Ohio Edison. Pursuant to the terms of a
Capital Contribution Agreement ("Ohio Edison Contribution Agreement"), filed as
Exhibit B-2 hereto, Ohio Edison will contribute its undivided interests in the
two Beaver Valley units and Beaver Valley common facilities and the common stock
of OES Nuclear Incorporated ("OES Nuclear"), a wholly-owned subsidiary of Ohio
Edison, which holds an undivided interest in Perry Unit 1, together with
associated decommissioning funds and its interests in other assets, inventories,
fuel, spare parts, equipment, supplies and contract rights relating to the
transferred units, to FE Nuclear as an additional capital contribution to FE
Nuclear. In connection with such transfer, FE Nuclear will initially assume Ohio
Edison's obligations in respect of $116 million aggregate principal amount of
PCRB obligations and certain other liabilities associated with the transferred
units. An additional $295 million of Ohio Edison's PCRBs are expected to be
assumed by FE Nuclear after the distribution described in the next paragraph.
The parties to the Ohio Edison Contribution Agreement have agreed that the value
of the contributed assets will be the net book value thereof as of the end of
the fiscal quarter immediately preceding the closing.

          Following the transfer of Ohio Edison's nuclear assets to FE Nuclear,
it is anticipated that OES Nuclear will be merged with and into FE Nuclear, and
Ohio Edison will distribute the stock of FE Nuclear as a dividend to its parent,
FirstEnergy, such that FE Nuclear will become a direct wholly-owned subsidiary
of FirstEnergy.

          If the transactions described above had occurred on March 31, 2005,
Ohio Edison's cost basis for the stock of FE Nuclear would have been equal to
the net book value of the transferred interests in the Beaver Valley and Perry
units and associated assets (approximately $712 million), less the initial PCRB
obligations to be assumed ($116 million) and the agreed upon value of other
liabilities assumed by FE Nuclear (approximately $596 million), resulting in no
charge to Ohio Edison's retained earnings.

          Sale of Nuclear Plants by Cleveland Electric and Toledo Edison.
Cleveland Electric and Toledo Edison have each entered into a Nuclear Purchase
and Sale Agreement with FE Nuclear ("Nuclear PSA"), filed herewith as Exhibits
B-3 and B-4, respectively, under which FE Nuclear has agreed to purchase
Cleveland Electric's and Toledo Edison's respective undivided ownership
interests in Beaver Valley Unit 2, Perry Unit 1 and Davis-Besse for a purchase
price equal to the net book value thereof, determined as of the end of the
fiscal quarter immediately preceding the closing, together with the respective
interests of Cleveland Electric and Toledo Edison in nuclear decommissioning
trust funds associated with those plants and their respective right, title and
interest in and to all contracts, fuel, spare parts, inventories, equipment,
supplies and other assets associated with each transferred unit, less the amount
of obligations of Cleveland Electric and Toledo Edison under PCRBs associated
with the transferred units ($367 million and $284 million, respectively, at
March 31, 2005), and the agreed upon value of certain other liabilities
associated with the transferred units.

          At closing, FE Nuclear will pay the purchase price, determined as
described in the previous paragraph, by delivering to Cleveland Electric and
Toledo Edison FE Nuclear Notes, in the form of Exhibit B-5 hereto, secured by a
lien on the transferred assets. Each FE Nuclear Note will bear interest at a
rate per annum based on the average weighted cost of long-term debt of Cleveland
Electric and Toledo Edison, as the case may be, determined as shown in Exhibit I


                                       5



hereto, will mature 20 years after the date of issuance, and will be prepayable
at any time, in whole or in part, at the option of FE Nuclear, without penalty.

          If the transactions described above had been consummated at March 31,
2005, the principal amounts of the FE Nuclear Notes delivered to Cleveland
Electric and Toledo Edison would have been approximately $469 million and $307
million, respectively.

          Repurchases of Common Stock of Cleveland Electric, Toledo Edison and
Penn Power. In connection with the transfer of the nuclear plants to FE Nuclear,
FirstEnergy intends to make a cash capital contribution to FE Nuclear of up to
$711 million. FE Nuclear will use the proceeds of this investment at or
subsequent to closing to prepay a like amount of the FE Nuclear Notes delivered
at closing to Penn Power, Cleveland Electric and Toledo Edison. In turn, Penn
Power, Cleveland Electric and Toledo Edison will apply the proceeds of such
prepayment of the FE Nuclear Notes, first, to repay outstanding borrowings under
the FirstEnergy System Utility Money Pool ("Money Pool")/4/ and, second, to the
extent that there are any remaining prepayment proceeds, to repurchase shares of
common stock of Cleveland Electric and Toledo Edison that are held by
FirstEnergy and shares of common stock of Penn Power that are held by Ohio
Edison. The purpose of these transactions is to adjust (i.e., reduce) the equity
and debt capitalization of Cleveland Electric, Toledo Edison and Penn Power to
mirror their smaller asset base after the transfer of their undivided interests
in the nuclear plants to FE Nuclear. On a pro forma basis, taking into account
the transfer of the nuclear plants to FE Nuclear and the related intercompany
financing transactions, common equity as a percentage of total capitalization of
Cleveland Electric, Toledo Edison, and Penn Power as of March 31, 2005 will
equal 46%, 56% and 56%, respectively./5/ On a pro forma basis, assuming
completion of the transactions described above, the $711 million capital
contribution by FirstEnergy, and FE Nuclear's repayment of the FE Nuclear Notes,
common equity as a percentage of FE Nuclear's total capitalization as of
December 31, 2005 would equal approximately 36%.

          1.4  External Debt Financing by FE Nuclear.
               --------------------------------------

          As indicated, upon completion of the transactions described in Item
1.3 above, FE Nuclear will become a direct public-utility subsidiary of
FirstEnergy. It is contemplated that FE Nuclear's requirements for additional
common equity (including the $711 million equity infusion by FirstEnergy at

----------
4     The Commission has previously authorized FirstEnergy and the Utility
      Subsidiaries to participate in the Utility Money Pool. See FirstEnergy
      Corp., et al., Holding Co. Act Release No. 27694 (June 30, 2003) (the
      "2003 Financing Order"). At March 31, 2005, outstanding borrowings under
      the Utility Money Pool by Cleveland Electric, Toledo Edison and Penn Power
      totaled $457.2 million, $395.5 million, and $10.5 million, respectively.

5     See pro forma balance sheets of Penn Power, Cleveland Electric and Toledo
      Edison, filed herewith as Exhibits FS-12, FS-13 and FS-14, respectively.
      Since the aggregate of Money Pool borrowings by Penn Power, Cleveland
      Electric and Toledo Edison exceeds $711 million at March 31, 2005, the pro
      formas do not reflect any stock repurchases.


                                       6



closing) will be satisfied by capital contributions by FirstEnergy pursuant to
Rule 45(b)(4).

          FE Nuclear herein requests authorization to issue and sell to
unaffiliated lenders, from time to time during the Authorization Period,
long-term debt securities having maturities of up to 50 years ("Long-term Debt")
and short-term debt securities having maturities of less than one year
("Short-term Debt") in an aggregate amount at any time outstanding not to exceed
$2.5 billion (the "FE Nuclear Debt Limit"). The following general terms will be
applicable where appropriate to Long-term Debt and Short-term Debt of FE
Nuclear:

          Effective Cost of Money. The effective cost of capital (i.e., the
aggregate of all payments, including interest, dividend distributions and other
periodic payments) in respect of Long-term Debt and Short-term Debt of FE
Nuclear will not exceed competitive market rates available at the time of
issuance for securities having the same or reasonably similar terms and
conditions issued by similar companies of reasonably comparable credit quality;
provided that, in no event will the effective cost of capital (i) on Long-term
Debt exceed at the time of issuance 500 basis points over the yield to maturity
of comparable-term U.S. Treasury securities if the interest rate on such
Long-term Debt securities is a fixed rate or, if the rate on such Long-term Debt
securities is a floating rate, 500 basis points over the London Interbank
Offered Rate ("LIBOR") for maturities of less than one year; and (ii) on
Short-term Debt exceed at the time of issuance, (A) in the case of commercial
paper or any other short-term borrowing that is not tied to a reference rate,
300 basis points over LIBOR, and (B) in the case of any short-term borrowing
that is tied to a reference rate, either (1) 300 basis points over LIBOR, (2) 50
basis points over the prime rate, as announced from time to time by CitiBank, or
any successor thereto, or (3) 100 basis points over the Federal Funds Rate,
whichever reference rate is applicable.

          Issuance Expenses. The underwriting fees, commissions or other similar
remuneration paid in connection with the non-competitive issue, sale or
distribution of a security pursuant to this Application/Declaration (not
including any original issue discount) will not exceed 5% of the principal or
total amount of the security being issued.

          Use of Proceeds. The proceeds from the sale of securities in external
financing transactions will be used for general corporate purposes, including
financing, in part, of the capital expenditures of FE Nuclear, financing of
working capital requirements of FE Nuclear, the acquisition, retirement or
redemption of securities (including PCRB obligations) previously issued by or on
behalf FE Nuclear, and other lawful purposes. The Applicants represent that no
such financing proceeds will be used to acquire the securities of any new
subsidiary unless such acquisition is consummated in accordance with an order of
the Commission (including the order issued in this proceeding) or an available
exemption under the Act or rules thereunder.

          Common Equity Ratio. FE Nuclear commits that it will maintain common
equity as a percentage of consolidated capitalization (common stock equity,
long-term debt and short-term debt, including current maturities of long-term
debt) at 30% or higher.


                                       7



          Ratings Event. With respect to the securities issuance authority
proposed in this Application/Declaration: (a) within four business days after
the occurrence of a Ratings Event,/6/ Applicants will notify the Commission of
its occurrence (by means of a letter, via fax, email or overnight mail to the
Office of Public Utility Regulation), and (b) within 30 days after the
occurrence of a Ratings Event, Applicants will submit a post-effective amendment
to this Application/Declaration explaining the material facts and circumstances
relating to that Ratings Event (including the basis on which, taking into
account the interests of investors, consumers and the public as well as other
applicable criteria under the Act, it remains appropriate for FE Nuclear to
issue the securities for which authorization has been requested in this
Application/Declaration, so long as FE Nuclear continues to comply with the
other applicable terms and conditions specified in the Commission's order
authorizing the transactions requested in this Application/Declaration).
Furthermore, except in accordance with a further order of the Commission, no
securities authorized as a result of this Application/Declaration will be issued
following the 60th day after a Ratings Event (other than Short-term Debt) if the
downgraded rating(s) has or have not been upgraded to investment grade.
Applicants request that the Commission reserve jurisdiction, through the
remainder of the Authorization Period, over the issuance of any securities
(other than Short-term Debt) that FE Nuclear is prohibited from issuing as a
result of the occurrence of a Ratings Event if no revised rating reflecting an
investment grade rating has been issued.

          1.5  Description of Specific Types of External Debt Securities of FE
               ---------------------------------------------------------------
Nuclear.
-------

          All debt securities issued by FE Nuclear in accordance with the
authorization requested herein, including, without limitation, securities issued
for the purpose of refunding or retiring outstanding securities, will comply
with the applicable parameters set forth in Item 1.4 above.

               1.5.1. Long-term Debt. Each series of Long-term Debt would have
such designation, aggregate principal amount, maturity, interest rate(s) or
methods of determining the same, terms of payment of interest, redemption
provisions, sinking fund terms and other terms and conditions as FE Nuclear may
determine at the time of issuance. Any Long-term Debt (a) may be secured or
unsecured, (b) may be senior or subordinated, (c) will have maturities ranging
from one to 50 years, (d) may be subject to optional and/or mandatory
redemption, in whole or in part, at par or at various premiums above the
principal amount thereof, (e) may be entitled to mandatory or optional sinking
fund provisions, (f) may provide for reset of the coupon pursuant to a
remarketing arrangement, (g) may be subject to tender or the obligation of the
issuer to repurchase at the election of the holder or upon the occurrence of a

----------
6     A "Ratings Event" will be deemed to have occurred if, during the
      Authorization Period, (i) any security issued by FE Nuclear upon original
      issuance, if rated, is rated below investment grade, or (ii) any
      outstanding security of FirstEnergy or FE Nuclear that is rated is
      downgraded below investment grade. For purposes of this provision, a
      security will be deemed "investment grade" if it is rated investment grade
      by at least one nationally recognized statistical rating organization, as
      that term is used in paragraphs (c)(2)(vi)(E), (F) and (H) of rule 15c3-1
      of the Securities Exchange Act of 1934, as amended).


                                       8



specified event, (h) may be called from existing investors by a third party, and
(i) may be entitled to the benefit of affirmative or negative financial or other
covenants.

          Long-term Debt may also be in the form of agreements between FE
Nuclear and one or more industrial development authorities ("IDAs") pursuant to
which an IDA agrees to issue PCRBs for the purpose of financing or refinancing
pollution control revenue facilities relating to FE Nuclear's nuclear power
plants./7/ Under the terms of any such agreement, payments to the issuing IDA
would be designed to match payments of principal of and interest on the PCRBs to
which such agreement relates.

          As security for FE Nuclear's obligations under any agreement relating
to any series of PCRBs, FE Nuclear requests authority to (1) issue its
promissory note or notes to evidence the loan to FE Nuclear of the proceeds of
the PCRBs by the issuing IDA, (2) acquire and deliver a letter of credit ("LOC")
guaranteeing payment of the PCRBs and enter into reimbursement agreements with
respect to any such LOC, (3) acquire insurance policies guaranteeing payment of
the PCRBs, and/or (4) pledge its first mortgage bonds as collateral for its
obligations to the issuing IDA, any trustee, LOC bank or PCRB insurer./8/ To
avoid double counting, it is proposed that the amount of any note or notes
issued by FE Nuclear to evidence the loan to FE Nuclear of the proceeds of any
PCRBs or first mortgage bonds issued by FE Nuclear as collateral security for
PCRB obligations not count against the FE Nuclear Debt Limit.

          The maturity date and interest rate and the redemption, sinking fund,
tender or repurchase features, if any, with respect to Long-term Debt of a
particular series (including any PCRBs), as well as any associated placement,
underwriting or selling agent fees, commissions and discounts, if any, will be
established by negotiation or competitive bidding.

               1.5.2. Short-term Debt. Short-term Debt of FE Nuclear may be in
the form of commercial paper, promissory notes and/or other forms of unsecured
short-term indebtedness. FE Nuclear may establish from time to time new
committed bank lines of credit, provided that only the principal amount of any
borrowings outstanding thereunder will be counted against the proposed FE
Nuclear Debt Limit. Credit lines may be set up for use by FE Nuclear for general
corporate purposes in addition to credit lines to support commercial paper as
described in this subsection. FE Nuclear will borrow and repay under such lines
of credit, from time to time, as it is deemed appropriate or necessary. FE
Nuclear may also engage in other types of short-term financing, including


----------
7     As described in Item 1.3 above, in connection with the transfer of the
      nuclear plants to FE Nuclear, FE Nuclear will assume approximately $1.1
      billion of PCRB obligations of the Utility Subsidiaries. FE Nuclear
      proposes to enter into agreements with the issuing IDAs to refinance these
      outstanding PCRBs.

8     FirstEnergy may also guarantee PCRB obligations of FE Nuclear pursuant to
      the authority previously granted under the 2003 Financing Order or any
      subsequent order issued by the Commission that authorizes FirstEnergy to
      guarantee obligations of its subsidiaries.


                                       9



borrowings under uncommitted lines, generally available to borrowers with
comparable credit ratings as it may deem appropriate in light of its needs and
market conditions at the time of issuance.

          Commercial paper would be sold in established domestic or European
commercial paper markets from time to time. Such commercial paper would be sold
to dealers at the discount rate or the coupon rate per annum prevailing at the
date of issuance for commercial paper of comparable quality and maturities sold
to commercial paper dealers generally. It is expected that the dealers acquiring
commercial paper from FE Nuclear will reoffer such paper at a discount to
corporate, institutional and, with respect to European commercial paper,
individual investors. Institutional investors are expected to include commercial
banks, insurance companies, pension funds, investment trusts, foundations,
colleges and universities and finance companies.

          1.6  Intrasystem Financing Transactions.
               ----------------------------------

          FE Nuclear further requests authorization to make direct long-term and
short-term borrowings from FirstEnergy ("Direct Borrowings"). All such Direct
Borrowings would be evidenced by FE Nuclear's promissory notes and would be
prepayable at any time without premium or penalty at FE Nuclear's option. The
aggregate principal amount of Direct Borrowings by FE Nuclear at any time
outstanding will be counted against the FE Nuclear Debt Limit. The interest rate
and maturity of any Direct Borrowings will be designed to parallel the terms
(i.e, effective cost of funds and maturity) of similar debt securities issued by
FirstEnergy, as authorized by the Commission in a separate proceeding./9/

          In addition, FE Nuclear requests authorization to become a participant
in and to make borrowings under the FirstEnergy System Non-Utility Money Pool
Agreement ("Non-Utility Money Pool") subject to terms and conditions previously
approved by the Commission./10/ FE Nuclear requests authorization to borrow up
to $1 billion at any time outstanding under the Non-Utility Money Pool.
Borrowings by FE Nuclear under the Non-Utility Money Pool would also be counted
against the proposed FE Nuclear Debt Limit.

----------
9     Under the 2003 Financing Order, FirstEnergy is authorized to issue
      long-term and short-term debt securities, subject to various restrictions
      and limitations, from time to time through December 31, 2005. FirstEnergy
      intends to file a new financing application later this year covering the
      issuance of such securities after December 31, 2005.

10    Under the 2003 Financing Order, FirstEnergy is currently authorized to
      maintain and make loans to its non-utility subsidiaries through the
      Non-Utility Money Pool. Although FE Nuclear will be an "electric utility
      company" for purposes of the Act, it will not be a state-regulated utility
      and therefore will be considered to be on the non-regulated side of
      FirstEnergy's business.

ITEM 2.  FEES, COMMISSIONS AND EXPENSES
         ------------------------------

          The fees, commissions and expenses incurred or to be incurred in
connection with the preparation and filing of this Application/Declaration are
not expected to exceed $35,000.

ITEM 3.  APPLICABLE STATUTORY PROVISIONS
         -------------------------------

          3.1  General.
               -------

          Sections 9(a) and 10 of the Act are applicable to Penn Power's
acquisition of the common stock of FE Nuclear, and Sections 9(a), 10, and 12(b)
of the Act and Rule 45 thereunder are applicable to the proposed acquisition by
Cleveland Electric, Toledo Edison and Penn Power of the FE Nuclear Notes.
Sections 12(d) and 12(f) of the Act and Rules 43 and 44 thereunder are
applicable to the transfer by the Utility Subsidiaries of their respective
interests in the nuclear plants to FE Nuclear, and Section 12(b) of the Act and
Rule 45 thereunder are applicable to FE Nuclear's assumption of PCRB obligations
and other liabilities of the Utility Subsidiaries related to the transferred
nuclear plants. Sections 9(a), 10 and 12(c) of the Act are applicable to the
proposed acquisition by Cleveland Electric and Toledo Edison of shares of their
common stock held by FirstEnergy and to the proposed acquisition by Penn Power
of shares of its common stock held by Ohio Edison. Section 12(c) of the Act and
Rule 46 thereunder are applicable to the transfer, by in-kind dividend, of the
common stock of FE Nuclear by Penn Power to Ohio Edison and of the common stock
of FE Nuclear by Ohio Edison to FirstEnergy. However, in each case, the dividend
distribution will be charged to retained earnings and not to capital or unearned
surplus and, therefore, should not require separate authorization by the
Commission. Sections 6(a) and 7 of the Act are applicable to FE Nuclear's
issuance of Long-term Debt and Short-term Debt. Sections 6(a), 7, 9, 10, and
12(b) of the Act are or may be applicable to agreements FE Nuclear enters into
with respect to PCRBs and to the intrasystem financing transactions described
herein.

          3.2  Rules 53 and 54.
               ---------------

          Under Rule 53(a), the Commission shall not make certain specified
findings under Sections 7 and 12 in connection with a proposal by a holding
company to issue securities for the purpose of acquiring the securities of or
other interest in any "exempt wholesale generator" ("EWG"), or to guarantee the
securities of any EWG, if each of the conditions in paragraphs (a)(1) through
(a)(4) thereof are met, provided that none of the conditions specified in
paragraphs (b)(1) through (b)(3) of Rule 53 exists. Rule 54 provides that the
Commission shall not consider the effect of the capitalization or earnings of
subsidiaries of a registered holding company that are EWGs or "foreign utility
companies" ("FUCOs") in determining whether to approve other transactions if
Rule 53(a), (b) and (c) are satisfied.

          FirstEnergy currently meets all of the conditions of Rule 53(a),
except for clause (1). Under the Merger Order and 2003 Financing Order, the
Commission, among other things, authorized FirstEnergy to invest in EWGs and
FUCOs so long as FirstEnergy's "aggregate investment," as defined in Rule
53(a)(1), in EWGs and FUCOs does not exceed $5 billion, which $5 billion amount


                                       11



is greater than the amount which would be permitted by clause (1) of Rule 53(a)
which, based on FirstEnergy's "consolidated retained earning," also as defined
in Rule 53(a)(1), of $1.9 billion as of March 31, 2005, would be $950 million.
The Merger Order and 2003 Financing Order also specify that this $5 billion
amount may include amounts invested in EWGs and FUCOs by FirstEnergy and GPU at
the time of the Merger Order ("Current Investments") and amounts relating to
possible transfers to EWGs of certain generating facilities owned by certain of
FirstEnergy's operating utilities ("GenCo Investments"). FirstEnergy has made
the commitment that through December 31, 2005, its aggregate investment in EWGs
and FUCOs other than the Current Investments and GenCo Investments ("Other
Investments") will not exceed $1.5 billion (the "Modified Rule 53 Test"). Under
the Merger Order and 2003 Financing Order, the Commission reserved jurisdiction
over Other Investments that exceed such $1.5 billion amount.

          As of March 31, 2005, FirstEnergy's aggregate investment in EWGs and
FUCOs was approximately $1 billion,/11/ an amount significantly below the $5
billion amount authorized in the Merger Order and 2003 Financing Order.
Additionally, as of March 31, 2005, FirstEnergy's consolidated retained earnings
were $1.9 billion. By way of comparison, FirstEnergy's consolidated retained
earnings as of December 31, 2001 were $1.52 billion.

          In any event, even taking into account the capitalization of and
earnings from EWGs and FUCOs in which FirstEnergy currently has an interest,
there would be no basis for the Commission to withhold approval of the
transactions proposed herein. With respect to capitalization, since the date of
the Merger Order, there has been no material adverse impact on FirstEnergy's
consolidated capitalization resulting from FirstEnergy's investments in EWGs and
FUCOs. As of March 31, 2005, FirstEnergy's consolidated capitalization consisted
of 43.4% common equity, 1.2% cumulative preferred stock, 53.8% long-term debt
and 1.6% notes payable. As of December 31, 2001, those ratios were as follows:
30.3% common equity, 3.1% cumulative preferred stock, 2.2% subsidiary-obligated
mandatorily redeemable preferred securities, 60.9% long term debt and 3.5% notes
payable. Additionally, the proposed transactions will not have any impact on
FirstEnergy's consolidated capitalization. Further, since the date of the Merger
Order, FirstEnergy's investments in EWGs and FUCOs have contributed positively
to its level of earnings, other than for the negative impact on earnings due to
FirstEnergy's writedowns of its investments in Avon Energy Partners Holdings
("Avon") and GPU Empresa Distribuidora Electrica Regional S.A. ("Emdersa")./12/


----------
11    This $1 billion amount represents Current Investments only. As of March
      31, 2005, FirstEnergy had no GenCo Investments.

12    At the time of the Merger Order, FirstEnergy identified certain former GPU
      EWG and FUCO investments for divestiture within one year. Among those
      identified were Avon, a holding company for Midlands Electricity plc, an
      electric distribution business in the United Kingdom and Emdersa and
      affiliates, an electric distribution business in Argentina. In May 2002,
      FirstEnergy sold 79.9% of its interest in Avon, and in the fourth quarter
      of 2002, recorded a $50 million charge ($32.5 million net of tax) to
      reduce the carrying value of its remaining 20.1% interest. The remaining
      20.1% interest in Avon was sold on January 16, 2004. Through 2002,
      FirstEnergy was unsuccessful in divesting GPU's former Argentina
      operations and made the decision to abandon its interest in Emdersa in
      early 2003. On April 18, 2003, FirstEnergy divested its ownership in
      Emdersa through the abandonment of its shares in Emdersa's parent company.
      FirstEnergy included in discontinued operations Emdersa's net income of $7
      million and a $67 million charge for the abandonment in the second quarter
      of 2003. An after-tax loss of $87 million (including $109 million in
      currency transaction losses arising principally from U.S. dollar
      denominated debt) was included in discontinued operations in 2002. In
      December 2003, Emdersa Guaracachi S. A. ("EGSA"), GPU Power's Bolivia
      subsidiary, was sold to Bolivia Integrated Energy Limited. FirstEnergy
      included in discontinued operations a $33 million loss on the sale of EGSA
      in the fourth quarter of 2003 and an operating loss for the year of $2
      million. On January 30, 2004, FirstEnergy sold its 28.67% interest in
      Termobarranquilla S. A., Empresa de Servicios Publicos ("TEBSA") for $12
      million. An impairment loss of $26 million related to TEBSA was recorded
      in December 2003 in Other Operating Expenses on the consolidated statement
      of income and no gain or loss was recognized upon the sale in 2004.
