BUCKEYE PARTNERS, L.P.

        We are a publicly traded master limited partnership that owns and operates a diversified network of integrated assets providing midstream logistic solutions, primarily consisting of the transportation, storage, and marketing of liquid petroleum products. We are one of the largest independent liquid petroleum products pipeline operators in the United States in terms of volumes delivered with approximately 6,000 miles of pipeline and more than 120 liquid petroleum products terminals with aggregate storage capacity of over 110 million barrels across our portfolio of pipelines, inland terminals, and an integrated network of marine terminals located primarily on the U.S. East Coast and in the Caribbean. Our flagship marine terminal in The Bahamas is one of the largest marine crude oil and petroleum products storage facilities in the world and provides an array of logistics and blending services for the global flow of petroleum products. Our network of marine terminals enables us to facilitate global flows of crude oil, refined petroleum products, and other commodities and to offer our customers connectivity to some of the world's most important bulk storage and blending hubs. In September 2014, we expanded our network of marine midstream assets by acquiring a controlling interest in a company with assets located in Corpus Christi, Texas and the Eagle Ford Shale. We are also a wholesale distributor of refined petroleum products in areas served by our pipelines and terminals. Finally, we also operate or maintain third-party pipelines under agreements with major oil and gas, petrochemical and chemical companies and perform certain engineering and construction management services for third parties.

RISK FACTORS

        An investment in our securities involves a significant degree of risk. Before you invest in our securities you should carefully consider those risks discussed in the "Forward-Looking Statements" section of this prospectus, the risk factors included in our most recent Annual Report on Form 10-K and as supplemented by our Quarterly Reports on Form 10-Q, each of which is incorporated herein by reference, and those risk factors that may be included in any applicable prospectus supplement, together with all of the other information included in this prospectus, any prospectus supplement and the documents we incorporate by reference in evaluating an investment in our securities.

        If any of the risks discussed in the foregoing documents were to occur, our business, financial condition, results of operations and cash flow could be materially adversely affected.

Table of Contents


HOW WE MAKE CASH DISTRIBUTIONS

        Set forth below is a summary of the significant provisions of our amended and restated partnership agreement that relate to distributions.

General

        Our amended and restated partnership agreement does not require distributions to be made quarterly or at any other time. Under our amended and restated partnership agreement, our general partner, from time to time and not less than quarterly, is required to review our accounts to determine whether distributions are appropriate. Our general partner is permitted to make such distributions as it may determine, without being limited to current or accumulated income or gains. Cash distributions may be made from any of our funds, including, without limitation, revenues, capital contributions or borrowed funds. Our general partner may also distribute other Partnership property, additional LP Units, or other securities of the Partnership or other entities. Distributions are made concurrently to all applicable record holders on the record date set for purposes of such distributions.

LP Units Eligible for Distributions

        The LP Units generally participate pro rata in our distributions. As of November 20, 2014, there were approximately 127,022,640 LP Units issued and outstanding. We currently have a long-term incentive plan and a unit deferral and incentive plan (together, the "LTIP") which provide for the issuance of up to 4,500,000 LP Units, subject to certain adjustments. As of November 20, 2014, there were 25,600 LP Units issuable upon exercise of options granted to employees pursuant to our unit option and distribution equivalent plan.

Distributions of Cash upon Liquidation

        If we dissolve in accordance with our amended and restated partnership agreement, we will sell or otherwise dispose of our assets in a process called a liquidation. We will first apply the proceeds of liquidation to the payment of our creditors, including by way of a reserve of cash or other assets of the Partnership for contingent liabilities. We will distribute any remaining proceeds to our unitholders, in accordance with their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation.

        If the sale of our assets in liquidation would be impracticable or would cause undue loss, the sale may be deferred for a reasonable amount of time or the assets (except those necessary to satisfy liabilities) may be distributed to our limited partners in lieu of cash in the same manner as cash or proceeds of a sale would have been distributed.

Table of Contents


THE PARTNERSHIP AGREEMENT

        The following is a summary of the material provisions of our amended and restated partnership agreement.

        The following provisions of our amended and restated partnership agreement are summarized elsewhere in this prospectus.

Organization and Duration

        The Partnership was organized on July 11, 1986 and has a term extending until the close of business on December 31, 2086.

Purpose

        The purpose of the Partnership under our amended and restated partnership agreement is to engage in any lawful activity for which limited partnerships may be organized under the Delaware Revised Uniform Limited Partnership Act ("DRULPA").

        Our general partner is authorized to perform all acts deemed necessary to carry out our purposes and to conduct our business.

Power of Attorney

        Each of our limited partners grants to our general partner and, if appointed, a liquidator, a power of attorney to, among other things, execute and file documents required for our qualification, continuance or dissolution.

Issuance of Additional Securities

        Our amended and restated partnership agreement authorizes our general partner to cause us to issue an unlimited number of additional limited partner interests and other equity securities for the consideration and on the terms and conditions established by our general partner without the approval of any limited partners. Without the prior approval of the holders of two-thirds of the outstanding LP Units, our general partner is prohibited from causing us to issue any class or series of limited partner interests having preferences or other special or senior rights over the previously outstanding LP Units. Without the approval of a majority of the holders of the outstanding LP Units, our general partner is prohibited from causing us to issue limited partner interests to itself or its affiliates unless the limited partner interests are of a class previously listed or admitted to trading on a national securities exchange and property is contributed to us with a value at least equal to the fair market value of the issued limited partner interests.

        It is possible that we will fund acquisitions, and other capital requirements, through the issuance of additional limited partner interests, including LP Units or other equity securities. Holders of any additional LP Units that we issue will be entitled to share with then-existing holders of LP Units in our distributions of available cash. In addition, the issuance of additional partnership interests may dilute (i) the percentage interests of then-existing holders of LP Units in our net assets and (ii) the voting rights of then-existing holders of LP Units under our amended and restated partnership agreement.

        The holders of LP Units do not have preemptive rights to acquire additional LP Units or other partnership interests.

Limited Liability

        Assuming that a limited partner does not participate in the control of our business within the meaning of the DRULPA and that it otherwise acts in conformity with the provisions of our amended and restated partnership agreement, the partner's liability under the DRULPA will be limited, subject to possible exceptions, to the amount of capital the partner is obligated to contribute to the Partnership for the partner's LP Units plus the partner's share of any undistributed profits and assets and any funds wrongfully distributed to it, as described below. If it were determined, however, that the right, or exercise of the right, by our limited partners as a group:

constituted "participation in the control" of our business for the purposes of the DRULPA, then the limited partners could be held personally liable for our obligations under the laws of Delaware, to the same extent as our general partner. This liability would extend to persons who transact business with us who reasonably believe that a limited partner is a general partner based on the limited partner's conduct. Neither our amended and restated partnership agreement nor the DRULPA specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner. Although this does not mean that a limited partner could not seek legal recourse, we know of no precedent for this type of a claim in Delaware case law.

        Under the DRULPA, a limited partnership may not make a distribution to a partner if, after the distribution, all liabilities of the limited partnership, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the limited partnership, would exceed the fair value of the assets of the limited partnership. For the purpose of determining the fair value of the assets of a limited partnership, the DRULPA provides that the fair value of property subject to liability for which recourse of creditors is limited will be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The DRULPA provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the DRULPA will be liable to the limited partnership for the amount of the distribution for three years from the date of distribution. Under the DRULPA, an assignee who becomes a substituted limited partner of a limited partnership is liable for the obligations of its assignor to make contributions to the limited partnership, excluding any obligations of the assignor with respect to wrongful distributions, as described above, except the assignee is not obligated for liabilities unknown to it at the time it became a limited partner and that could not be ascertained from the partnership agreement.

        Our subsidiaries conduct business in multiple jurisdictions. Maintenance of our limited liability as a limited partner or member of our subsidiaries formed as limited partnerships or limited liability companies may require compliance with legal requirements in the jurisdictions in which such subsidiaries conduct business, including qualifying our subsidiaries to do business there. Limitations on the liability of a limited partner or member for the obligations of a limited partnership or limited liability company have not been clearly established in many jurisdictions. If it were determined that we were, by virtue of our limited partner interest or limited liability company interest in our subsidiaries or otherwise, conducting business in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right or exercise of the right by the limited partners as a group to elect members of the board of directors of our general partner, to remove or replace our general partner, to approve certain amendments to our amended and restated partnership agreement, or to take other action under our amended and restated partnership agreement constituted

10


Table of Contents

"participation in the control" of our business for purposes of the statutes of any relevant jurisdiction, then the limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We will operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.

Voting Rights

        The following matters require the vote of our unitholders as specified below.

Election of the board of directors of our general partner

  All directors on the board of directors of our general partner will be elected by a plurality of the votes cast at meetings of the limited partners. Please read "—Meetings; Voting."

Amendment of the amended and restated partnership agreement

 

Certain amendments may be made by our general partner without the approval of our unitholders. Certain other amendments require the approval of holders of a majority of outstanding LP Units. Certain other amendments require the approval of holders of a super-majority of outstanding LP Units. Please read "—Amendment of Our Amended and Restated Partnership Agreement."

Sale of all or substantially all of the Partnership's assets

 

Holders of two-thirds of outstanding LP Units. Please read "—Merger, Sale or Other Disposition of Assets."

Dissolution of the Partnership

 

Holders of two-thirds of outstanding LP Units. Please read "—Termination and Dissolution."

Removal/Replacement of our general partner

 

Holders of 80% of outstanding LP Units. Please read "—Withdrawal or Removal of Our General Partner."

Amendment of Our Amended and Restated Partnership Agreement

        General.    Amendments to our amended and restated partnership agreement may be proposed only by our general partner. To adopt a proposed amendment, other than certain amendments discussed below, our general partner must seek written approval of the holders of the number of units required to approve the amendment or call a meeting of the limited partners to consider and vote upon the proposed amendment. Except as otherwise described below, an amendment must be approved by the limited partners holding in the aggregate at least a majority of the outstanding LP Units, referred to as a "Majority Interest." No amendments to certain provisions and definitions in our amended and restated partnership agreement relating to or requiring "special approval" or the approval of a majority of the members of the audit committee of the board of directors of our general partner may be made without first obtaining such special approval.

        No Unitholder Approval.    Our general partner may generally make amendments to our amended and restated partnership agreement without the approval of any limited partner or assignee to reflect:

11


Table of Contents

        In addition, our general partner may make amendments to our amended and restated partnership agreement without the approval of any limited partner or assignee if those amendments, in the discretion of our general partner, reflect:

        Opinion of Counsel and Partnership Unitholder Approval.    No amendments to our amended and restated partnership agreement will become effective without the approval of holders of at least 80% of the LP Units unless we obtain an opinion of counsel to the effect that the amendment will not result in the loss of limited liability of any of our limited partners or cause us or any of our operating partnerships to be treated as an association taxable as a corporation for federal income tax purposes.

        Any amendment to our amended and restated partnership agreement that reduces the voting percentage required to take any action must be approved by the affirmative vote of our limited partners constituting not less than the voting requirement sought to be reduced.

Merger, Sale or Other Disposition of Assets

        Our amended and restated partnership agreement generally prohibits our general partner, without the prior approval of the holders of at least two-thirds of the outstanding LP Units and special approval, from causing us to, among other things, sell, exchange or otherwise dispose of all or substantially all of the consolidated assets owned by us and our operating partnerships. In addition, our amended and restated partnership agreement generally prohibits our general partner from causing us to merge or consolidate with another entity without special approval. Our general partner may, however, mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our assets without the approval of the holders of outstanding LP Units and without special approval.

Table of Contents

Withdrawal or Removal of Our General Partner

        Our general partner may withdraw as general partner of the Partnership by giving 90 days' advance written notice, provided such withdrawal is approved by the vote of the holders of not less than 80% of the outstanding LP Units or we receive an opinion of counsel regarding limited liability and tax matters.

        Upon receiving notice of the withdrawal of our general partner, prior to the effective date of such withdrawal, the holders of LP Units representing a Majority Interest may select a successor to the withdrawing general partner. If a successor is not elected, we will be dissolved, wound up and liquidated, unless within 90 days of that withdrawal, all of our partners agree in writing to continue our business and to appoint a successor general partner. Please read "—Termination and Dissolution" below.

        Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than 80% of the outstanding LP Units, we receive an opinion of counsel regarding limited liability and tax matters, the successor general partner or an affiliate thereof agrees to indemnify and hold harmless our general partner and its affiliates from any liability or obligation arising out of, or causes the general partner and its affiliates to be released from, any and all liabilities and obligations (including loan guarantees) under fringe benefit plans sponsored by the general partner or any of its affiliates in connection with our business, except as otherwise prohibited by our amended and restated partnership agreement, and all required regulatory approvals for removal of our general partner shall have been obtained. Any removal of our general partner is also subject to the approval of a successor general partner by the vote of the holders of LP Units representing a Majority Interest and the agreement of the successor general partner or one of its affiliates to indemnify the removed general partner against, or to cause it to be released from, certain liabilities.

        If our general partner withdraws or is removed, we are required to reimburse the departing general partner for all amounts due the departing general partner.

Transfer of General Partner Interest

        Our general partner is prohibited under our amended and restated partnership agreement from transferring its general partner interest.

Termination and Dissolution

        We will continue as a limited partnership until the close of business on December 31, 2086 or until earlier terminated under our amended and restated partnership agreement. We will dissolve upon:

        Upon a dissolution under clause (2) or (3) and the failure of all partners to agree in writing to continue our business and to elect a successor general partner, the holders of LP Units representing a Majority Interest may also elect, within 180 days of such dissolution, to reconstitute the Partnership and continue our business on the same terms and conditions described in our amended and restated partnership agreement by forming a new limited partnership on terms identical to those in our amended and restated partnership agreement and having as general partner a person approved by the holders of LP Units representing a Majority Interest subject to our receipt of an opinion of counsel to the effect that:

Liquidation and Distribution of Proceeds

        Upon our dissolution, unless we are reconstituted and continued as a new partnership by the holders of LP Units representing a Majority Interest, our general partner or, if our general partner has withdrawn, been removed, dissolved or become bankrupt, the liquidator authorized to wind up our affairs will, acting with all of the powers of our general partner that the liquidator deems appropriate or necessary in its good faith judgment, liquidate our assets and apply and distribute the proceeds of the liquidation as described in "How We Make Cash Distributions—Distributions of Cash Upon Liquidation."

Meetings; Voting

        For purposes of determining the holders of LP Units entitled to notice of or to vote at any meeting or to give approvals without a meeting, our general partner may set a record date, which date for purposes of notice of a meeting shall not be less than 10 days nor more than 60 days before the date of the meeting. If a meeting is adjourned, notice need not be given of the adjourned meeting and a new record date does not need to be set, if the time and place thereof are announced at the meeting at which the adjournment is taken, unless such adjournment (together with any prior adjournments that did not have a new record date set) is for more than 60 days. The Partnership may transact any business at the adjourned meeting that might have been transacted at the original meeting.

        Any action that is required or permitted to be taken by our unitholders may be taken either at a meeting of our unitholders or without a meeting if consents in writing describing the action so taken are signed by holders of the number of units necessary to authorize or take that action at a meeting, except that election of directors by unitholders may only be done at a meeting. Special meetings of our unitholders may be called by our general partner or by our unitholders owning at least 20% of the outstanding LP Units.

        Annual meetings of limited partners for the election of directors to the board of directors of our general partner (as described below), and such other matters as the board of directors of our general partner submits to a vote of the limited partners, will be held on the first Tuesday in June of each year or on such other date as is fixed by our general partner. Unitholders may vote either in person or by proxy at meetings. The holders of a majority of the outstanding LP Units, represented in person or by proxy, will constitute a quorum.

        Except as described below with respect to the election of directors, each record holder of a LP Unit has one vote per LP Unit, although additional limited partner interests having special voting rights could be issued. Please read "—Issuance of Additional Securities." LP Units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and its nominee provides otherwise. With respect to the election of directors, our amended and restated partnership agreement provides that if, at any time, any person or group beneficially owns 20% or more of the outstanding LP Units, then all LP Units owned by such person or group in excess of 20% of the outstanding LP Units may not be voted, and in each case, the foregoing LP Units will not be counted when calculating the required votes for such matter and will not be deemed to be outstanding for purposes of determining a quorum for such meeting. Such LP Units will not be treated as a separate class for purposes of our amended and restated partnership agreement. Notwithstanding the foregoing, the board of directors of our general partner may, by action specifically referencing votes for the election of directors, determine that the limitation described above will not apply to a specific person or group.

Board of Directors

        General.    The number of directors of our general partner's board will be not less than six and not more than eleven. Any decrease in the number of directors by our general partner's board may not have the effect of shortening the term of any incumbent director. The board of directors of our general partner must maintain at least three directors meeting the independence and experience requirements of any national securities exchange on which our LP Units are listed or quoted

        Directors.    Our directors are classified with respect to their terms of office by dividing them into three classes, each class to be as nearly equal in number as possible. The directors that are designated to Class I will serve for a term that expires at the 2017 annual meeting, the directors designated to Class II will serve for a term that expires at the 2015 annual meeting, and the directors designated to Class III will serve for a term that expires at the 2016 annual meeting. At each annual meeting of our unitholders, directors to replace directors whose terms expire at such annual meeting will be elected to hold office until the third succeeding annual meeting. Each director will hold office for the term for which such director is elected or until such director's earlier death, resignation or removal. Any vacancies may be filled by a majority of the remaining directors then in office. A director may be removed only for cause and only upon a vote of the majority of the remaining directors then in office.

        Nominations of Directors.    Nominations of persons for election as directors may be made at an annual meeting of the limited partners only (a) by or at the direction of the directors or any committee thereof or (b) by any public limited partner who (i) was a record holder at the time the notice provided for in our amended and restated partnership agreement is delivered to our general partner, (ii) is entitled to vote at the meeting and (iii) complies with the notice procedures set forth in our amended and restated partnership agreement.

        For any nominations brought before an annual meeting by a public limited partner, the limited partner must give timely notice thereof in writing to our general partner. The notice must contain certain information as described in our amended and restated partnership agreement. To be timely, a public limited partner's notice must be delivered to our general partner not later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the first anniversary of the preceding year's annual meeting (provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 70 days after such anniversary date, notice by the limited partner must be so delivered not earlier than the close of business on 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 by us or our general partner). The public announcement of an adjournment or postponement of an annual meeting will not commence a new time period (or extend any time period) for the giving of a limited partner's notice as described above.

        In the event that the number of directors is increased effective at an annual meeting and there is no public announcement by us or our general partner naming the nominees for the additional directorships at least 100 days prior to the first anniversary of the preceding year's annual meeting, a public limited partner's notice will also be considered timely, but only with respect to nominees for the additional directorships, if it is delivered to our general partner not later than the close of business on the 10th day following the day on which such public announcement is first made by us or our general partner.

        Nominations of persons for election as directors also may be made at a special meeting of limited partners at which directors are to be elected in accordance with the provisions of our amended and restated partnership agreement.

        Only such persons who are nominated in accordance with the procedures set forth in our amended and restated partnership agreement will be eligible to be elected at an annual or special meeting of

limited partners to serve as directors. Notwithstanding the foregoing, unless otherwise required by law, if the public limited partner who nominated a person to serve as a director (or a qualified representative of the limited partner) does not appear at the annual or special meeting of limited partners to present such nomination, such nomination will be disregarded notwithstanding that proxies in respect of such vote may have been received by our general partner or us.

        In addition to the provisions described above and in our amended and restated partnership agreement, a public limited partner must also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder; provided, however, that any references in our amended and restated partnership agreement to the Exchange Act or the rules promulgated thereunder are not intended to and do not limit any requirements applicable to nominations pursuant to our amended and restated partnership agreement, and compliance with our amended and restated partnership agreement is the exclusive means for a limited partner to make nominations.

Indemnification

        Our amended and restated partnership agreement and the agreements of limited partnership or operating agreements of our subsidiaries, as the case may be (together with our amended and restated partnership agreement, the "Organizational Agreements") provide that we or our subsidiaries, as the case may be, shall indemnify (to the extent permitted by applicable law) certain persons (each, an "Indemnitee") against expenses (including legal fees and expenses), judgments, fines and amounts paid in settlement actually and reasonably incurred by such Indemnitee in connection with any threatened, pending or completed claim, demand, action, suit or proceeding (a "claim") to which the Indemnitee is or was an actual or threatened party and which relates to the Organizational Agreements or our, or any of our subsidiaries', property, business, affairs or management. This indemnity is available only if the Indemnitee acted in good faith and the action or omission which is the basis of such claim, demand, action, suit or proceeding does not involve the gross negligence or willful misconduct of such Indemnitee. Indemnitees include our general partner, any affiliates of such general partner, any person who is or was a director, officer, manager, member, employee or agent of such general partner or any affiliate, or any person who is or was serving at the request of such general partner or any such affiliate as a director, officer, manager, member, partner, trustee, employee or agent of another individual, corporation, limited liability company, partnership, trust, unincorporated organization, association or other entity; and an Indemnitee shall be indemnified only in connection with any claim made by reason of such Indemnitee's status as such or any action taken or omitted to be taken in the Indemnitee's capacity as such. Expenses subject to indemnity will be paid by us to the Indemnitee in advance, subject to receipt of an undertaking by or on behalf of the Indemnitee to repay such amount if it is ultimately determined by a court of competent jurisdiction that the Indemnitee is not entitled to indemnification. We maintain a liability insurance policy on behalf of certain of the Indemnitees.

        Section 18-108 of the Delaware Limited Liability Company Act provides that, subject to such standards and restrictions set forth in its limited liability company agreement, a Delaware limited liability company may indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever. Article V of the amended and restated limited liability company agreement of our general partner currently provides for the indemnification of affiliates of our general partner and members, managers, partners, officers, directors, employees, agents and trustees of our general partner or any affiliate of our general partner and such persons who serve at the request of our general partner as members, managers, partners, officers, directors, employees, agents, trustees and fiduciaries of any other enterprise against certain liabilities under certain circumstances.

PLAN OF DISTRIBUTION

        We may use this prospectus, any accompanying prospectus supplement and any related free writing prospectus to sell the LP Units from time to time in one or more transactions as follows: (1) through agents, (2) through underwriters or dealers, (3) directly to one or more purchasers, (4) pursuant to delayed delivery contracts or forward contracts, (5) through a combination of these methods or (6) through any other method permitted by applicable law.

By Agents

        LP Units may be sold, from time to time, through agents designated by us. Unless otherwise indicated in a prospectus supplement, the agents will agree to use their reasonable best efforts to solicit purchases for the period of their appointment.

By Underwriters

        If underwriters are used in the sale, the LP Units of the series offered will be acquired by the underwriters for their own account. The underwriters may resell the LP Units in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of resale. The obligations of the underwriters to purchase the LP Units of the series offered will be subject to certain conditions. The underwriters will be obligated to purchase all the LP Units of the series offered if any of the securities are purchased. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

        If we utilize a dealer in the sale, we will sell the LP Units to the dealer, as principal. The dealer may then resell the LP Units to the public at varying prices to be determined by the dealer at the time of resale.

        To the extent that we make sales through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a sales agency financing agreement or other at-the-market offering arrangement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to any such agreement, we will issue and sell LP Units through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell LP Units on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The agreement will provide that any LP Units sold will be sold at prices related to the then prevailing market prices for such securities. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time. Pursuant to the terms of the agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of LP Units. The terms of each such agreement will be set forth in more detail in the applicable prospectus supplement and any related free writing prospectus. In the event that any underwriter or agent acts as principal, or broker-dealer acts as underwriter, it may engage in certain transactions that stabilize, maintain, or otherwise affect the price of LP Units. We will describe any such activities in the prospectus supplement or any related free writing prospectus relating to the transaction.

Direct Sales

        LP Units may also be sold directly by us from time to time. In this case, no underwriters or agents would be involved. We may use electronic media, including the Internet, to sell offered securities directly.

Table of Contents

Delayed Delivery Contracts or Forward Contracts

        If indicated in the prospectus supplement, we will authorize agents, underwriters or dealers to solicit offers to purchase LP Units from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts or forward contracts providing for payment or delivery on a specified date in the future at prices determined as described in the prospectus supplement. Such contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

General Information

        Underwriters, dealers and agents that participate in the distribution of the LP Units may be underwriters as defined in the Securities Act of 1933, as amended, and any discounts or commissions received by them from us and any profit on the resale of the LP Units by them may be treated as underwriting discounts and commissions under the Securities Act. Any underwriters or agents will be identified and their compensation will be described in a prospectus supplement.

        We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute with respect to payments which the underwriters, dealers or agents may be required to make because of those liabilities.

        Underwriters, dealers and agents or their affiliates may engage in transactions with, or perform services for, us or our affiliates in the ordinary course of their businesses.

MATERIAL TAX CONSEQUENCES

        This section summarizes the material U.S. federal income tax consequences that may be relevant to prospective unitholders and is based upon current provisions of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), existing and proposed U.S. Treasury regulations thereunder (the "Treasury Regulations"), and current administrative rulings and court decisions, all of which are subject to change. Changes in these authorities may cause the U.S. federal income tax consequences to a prospective unitholder to vary substantially from those described below, possibly on a retroactive basis. Unless the context otherwise requires, references in this section to "us" or "we" are references to Buckeye Partners, L.P. and our operating subsidiaries.

        Legal conclusions contained in this section, unless otherwise noted, are the opinion of Vinson & Elkins L.L.P. insofar as they relate to matters of U.S. federal income tax law and are based on the accuracy of representations made by us to them for this purpose. However, this section does not address all federal income tax matters that affect us or our unitholders and does not describe the application of the alternative minimum tax that may be applicable to certain unitholders. Furthermore, this section focuses on unitholders who are individual citizens or residents of the United States (for federal income tax purposes), whose functional currency is the U.S. dollar, who use the calendar year as their taxable year, and who hold LP Units as capital assets (generally, property that is held for investment). This section has only limited applicability to corporations, partnerships (and entities treated as partnerships for U.S. federal income tax purposes), estates, trusts, non-resident aliens or other unitholders subject to specialized tax treatment, such as tax-exempt institutions, non-U.S. persons, individual retirement accounts ("IRAs"), employee benefit plans, real estate investment trusts or mutual funds. Accordingly, we encourage each prospective unitholder to consult such unitholder's own tax advisor in analyzing the federal, state, local and non-U.S. tax consequences that are particular to that unitholder resulting from its ownership or disposition of its LP Units and potential changes in applicable tax laws.

        We are relying on opinions and advice of Vinson & Elkins L.L.P. with respect to the matters described herein. An opinion of counsel represents only that counsel's best legal judgment and does not bind the Internal Revenue Service (the "IRS") or a court. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS. Any such contest of the matters described herein may materially and adversely impact the market for our LP Units and the prices at which such LP Units trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders because the costs will reduce our cash available for distribution. Furthermore, the tax consequences of an investment in us may be significantly modified by future legislative or administrative changes or court decisions, which may be retroactively applied.

        For the reasons described below, Vinson & Elkins L.L.P. has not rendered an opinion with respect to the following federal income tax issues: (1) the treatment of a unitholder whose LP Units are the subject of a securities loan (e.g., a loan to a short seller to cover a short sale of LP Units) (please read "—Tax Consequences of LP Unit Ownership—Treatment of Securities Loans"); (2) whether our monthly convention for allocating taxable income and losses is permitted by existing Treasury Regulations (please read "—Disposition of LP Units—Allocations Between Transferors and Transferees"); and (3) whether our method for taking into account Section 743 adjustments is sustainable in certain cases (please read "Tax Consequences of LP Unit Ownership—Section 754 Election" and "—Uniformity of LP Units").

Taxation of the Partnership

        Partnership Status.    We are treated as a partnership for U.S. federal income tax purposes and, therefore, generally will not be liable for entity-level federal income taxes. Instead, as described below, each of our unitholders will take into account its respective share of our items of income, gain, loss and

19


Table of Contents

deduction in computing its federal income tax liability as if the unitholder had earned such income directly, even if no cash distributions are made to the unitholder.

        Section 7704 of the Code generally provides that publicly traded partnerships will be treated as corporations for federal income tax purposes. However, if 90% or more of a partnership's gross income for every taxable year it is publicly traded consists of "qualifying income," the partnership may continue to be treated as a partnership for U.S. federal income tax purposes (the "Qualifying Income Exception"). Qualifying income includes (i) income and gains derived from the transportation, storage, refining, processing and marketing of crude oil, natural gas and products thereof (including NGLs), (ii) interest (other than from a financial business), (iii) dividends, (iv) gains from the sale of real property and (v) gains from the sale or other disposition of capital assets held for the production of qualifying income. We estimate that less than 5% of our current gross income is not qualifying income; however, this estimate could change from time to time.

        Based upon factual representations made by us and our general partner, Vinson & Elkins L.L.P. is of the opinion that we will be treated as a partnership for federal income tax purposes. The representations made by us and our general partner upon which Vinson & Elkins L.L.P. has relied in rendering its opinion include, without limitation:

        We believe that these representations are true and will be true in the future.

        If we fail to meet the Qualifying Income Exception, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery (in which case the IRS may also require us to make adjustments with respect to our unitholders or pay other amounts), we will be treated as transferring all of our assets, subject to liabilities, to a newly formed corporation, on the first day of the year in which we fail to meet the Qualifying Income Exception, in return for stock in that corporation and then as distributing that stock to our unitholders in liquidation of their interests in us. This deemed contribution and liquidation should not result in the recognition of taxable income by our unitholders or us so long as our liabilities do not exceed the tax basis of our assets. Thereafter, we would be treated as an association taxable as a corporation for federal income tax purposes.

        The present federal income tax treatment of publicly traded partnerships, including us, or an investment in our LP Units may be modified by administrative or legislative action or judicial interpretation at any time. For example, from time to time, members of the U.S. Congress propose and consider substantive changes to the existing federal income tax laws that affect publicly traded partnerships. One such legislative proposal would have eliminated the Qualifying Income Exception upon which we rely for our treatment as a partnership for U.S. federal income tax purposes. We are unable to predict whether any such changes will ultimately be enacted. However, it is possible that a change in law could affect us and may be applied retroactively. Any such changes could negatively impact the value of an investment in our LP Units.

20


Table of Contents

        If for any reason we are taxable as a corporation in any taxable year, our items of income, gain, loss and deduction would be taken into account by us in determining the amount of our liability for federal income tax, rather than being passed through to our unitholders. Accordingly, our taxation as a corporation would materially reduce the cash available for distribution to unitholders and thus would likely substantially reduce the value of our LP Units. In addition, any distribution made to a unitholder at a time we are treated as a corporation would be (i) a taxable dividend to the extent of our current or accumulated earnings and profits then (ii) a nontaxable return of capital to the extent of the unitholder's tax basis in our LP Units and thereafter (iii) taxable capital gain.

        The remainder of this discussion is based on Vinson & Elkins L.L.P.'s opinion that we will be treated as a partnership for federal income tax purposes.

Tax Consequences of LP Unit Ownership

        Limited Partner Status.    Unitholders who are admitted as limited partners of Buckeye Partners, L.P. as well as unitholders whose units are held in street name or by a nominee and who have the right to direct the nominee in the exercise of all substantive rights attendant to the ownership of units, will be treated as partners of Buckeye Partners, L.P. for federal income tax purposes. For a discussion related to the risks of losing partner status as a result of securities loans, please read "—Treatment of Securities Loans." Unitholders who are not treated as partners of the partnership as described above are urged to consult their own tax advisors with respect to their tax consequences of holding LP Units in Buckeye Partners, L.P.

        Flow-Through of Taxable Income.    Subject to the discussion below under "—Entity-Level Collections of Unitholder Taxes" with respect to payments we may be required to make on behalf of our unitholders, we will not pay any federal income tax. Rather, each unitholder will be required to report on its federal income tax return each year its share of our income, gains, losses and deductions for our taxable year or years ending with or within its taxable year. Consequently, we may allocate income to a unitholder even if that unitholder has not received a cash distribution.

        Basis of LP Units.    A unitholder's tax basis in its LP Units initially will be the amount paid for those LP Units plus the unitholders initial allocable share of our liabilities. That basis generally will be (i) increased by the unitholder's share of our income and by any increases in such unitholder's share of our liabilities, and (ii) decreased, but not below zero, by the amount of all distributions to the unitholder, the unitholder's share of our losses, and any decreases in the unitholder's share of our liabilities. The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all of those interests.

        Treatment of Distributions.    Distributions made by us to a unitholder generally will not be taxable to the unitholder, unless such distributions exceed the unitholder's tax basis in its LP Units, in which case the unitholder will recognize gain taxable in the manner described below under "—Disposition of LP Units."

        Any reduction in a unitholder's share of our "liabilities" will be treated as a distribution by us of cash to that unitholder. A decrease in a unitholder's percentage interest in us because of our issuance of additional LP Units may decrease the unitholder's share of our liabilities. For purposes of the foregoing, a unitholder's share of our nonrecourse liabilities (liabilities for which no partner bears the economic risk of loss) generally will be based upon that unitholder's share of the unrealized appreciation (or depreciation) in our assets, to the extent thereof, with any excess liabilities allocated based on the unitholder's share of our profits. Please read "—Disposition of LP Units."

        A non-pro rata distribution of money or property (including a deemed distribution as a result of the reallocation of our liabilities described above) may cause a unitholder to recognize ordinary

21


Table of Contents

income, if the distribution reduces the unitholder's share of our "unrealized receivables," including depreciation and depletion recapture and substantially appreciated "inventory items," both as defined in Section 751 of the Code ("Section 751 Assets"). To the extent of such reduction, the unitholder would be deemed to receive its proportionate share of the Section 751 Assets and exchange such assets with us in return for an allocable portion of the non-pro rata distribution. This deemed exchange generally will result in the unitholder's recognition of ordinary income in an amount equal to the excess of (1) the non-pro rata portion of that distribution over (2) the unitholder's tax basis (generally zero) in the Section 751 Assets deemed to be relinquished in the exchange.

        Limitations on Deductibility of Losses.    The deduction by a unitholder of its share of our losses will be limited to the lesser of (i) the unitholder's tax basis in its LP Units, and (ii) in the case of a unitholder that is an individual, estate, trust or certain types of closely-held corporations, the amount for which the unitholder is considered to be "at risk" with respect to our activities. In general, a unitholder will be at risk to the extent of its tax basis in its LP Units, reduced by (1) any portion of that basis attributable to the unitholder's share of our liabilities, (2) any portion of that basis representing amounts otherwise protected against loss because of a guarantee, stop loss agreement or similar arrangement and (3) any amount of money the unitholder borrows to acquire or hold its LP Units, if the lender of those borrowed funds owns an interest in us, is related to another unitholder or can look only to the LP Units for repayment.

        A unitholder subject to the at risk limitation must recapture losses deducted in previous years to the extent that distributions (including distributions deemed to result from a reduction in a unitholder's share of nonrecourse liabilities) cause the unitholder's at risk amount to be less than zero at the end of any taxable year. Losses disallowed to a unitholder or recaptured as a result of the basis or at risk limitations will carry forward and will be allowable as a deduction in a later year to the extent that the unitholder's tax basis or at risk amount, whichever is the limiting factor, is subsequently increased. Upon a taxable disposition of LP Units, any gain recognized by a unitholder can be offset by losses that were previously suspended by the at risk limitation but not losses suspended by the basis limitation. Any loss previously suspended by the at risk limitation in excess of that gain can no longer be used, and will not be available to offset a unitholder's salary or active business income.

        In addition to the basis and at risk limitations, passive activity loss limitations generally limit the deductibility of losses incurred by individuals, estates, trusts, some closely held corporations and personal service corporations from "passive activities" (generally, trade or business activities in which the taxpayer does not materially participate). The passive loss limitations are applied separately with respect to each publicly-traded partnership. Consequently, any passive losses we generate will be available to offset only our passive income. Passive losses that exceed a unitholder's share of passive income we generate may be deducted in full when the unitholder disposes of all of its LP Units in a fully taxable transaction with an unrelated party. The passive activity loss rules are generally applied after other applicable limitations on deductions, including the at risk and basis limitations.

        Limitations on Interest Deductions.    The deductibility of a non-corporate taxpayer's "investment interest expense" is generally limited to the amount of that taxpayer's "net investment income." Investment interest expense includes:

        The computation of a unitholder's investment interest expense will take into account interest on any margin account borrowing or other loan incurred to purchase or carry an LP Unit. Net investment income includes gross income from property held for investment and amounts treated as portfolio

22


Table of Contents

income under the passive loss rules, less deductible expenses other than interest directly connected with the production of investment income. Net investment income generally does not include qualified dividend income (if applicable) or gains attributable to the disposition of property held for investment. A unitholder's share of a publicly-traded partnership's portfolio income and, according to the IRS, net passive income will be treated as investment income for purposes of the investment interest expense limitation.

        Entity-Level Collections of Unitholder Taxes.    If we are required or elect under applicable law to pay any federal, state, local or non-U.S. tax on behalf of any current or former unitholder, we are authorized to treat the payment as a distribution of cash to the relevant unitholder. Where tax is payable on behalf of all unitholders or the relevant unitholder's identity cannot be determined, we are authorized to treat the payment as a distribution to all current unitholders. We are authorized to amend our partnership agreement in the manner necessary to maintain uniformity of intrinsic tax characteristics of units and to adjust later distributions, so that after giving effect to these distributions, the priority and characterization of distributions otherwise applicable under our partnership agreement is maintained as nearly as is practicable. Payments by us as described above could give rise to an overpayment of tax on behalf of a unitholder, in which event the unitholder may be entitled to claim a refund of the overpayment amount. Unitholders are urged to consult their tax advisors to determine the consequences to them of any tax payment we make on their behalf.

        Allocation of Income, Gain, Loss and Deduction.    In general, our items of income, gain, loss and deduction will be allocated among the unitholders in accordance with their percentage interests in us. At any time that incentive distributions are made to our general partner, gross income will be allocated to the recipients to the extent of these distributions. However, specified items of our income, gain, loss and deduction will be allocated under Section 704(c) of the Code (or the principles of Section 704(c) of the Code) to account for any difference between the tax basis and fair market value of our assets at the time such assets are contributed to us and any time we issue additional LP Units (a "Book-Tax Disparity"). As a result, the federal income tax burden associated with any Book-Tax Disparity immediately prior to an offering generally will be borne by our partners holding interests in us prior to such offering. In addition, items of recapture income will be specially allocated to the extent possible to the unitholder who was allocated the deduction giving rise to that recapture income in order to minimize the recognition of ordinary income by other unitholders.

        An allocation of items of our income, gain, loss or deduction, other than an allocation required by the Code to eliminate a Book-Tax Disparity, will generally be given effect for federal income tax purposes in determining a partner's share of an item of income, gain, loss or deduction only if the allocation has "substantial economic effect" as determined under Treasury Regulations. If an allocation does not have substantially economic effect, it will be reallocated to our unitholders on the basis of their interests in us, which will be determined by taking into account all the facts and circumstances, including

        Vinson & Elkins L.L.P. is of the opinion that, with the exception of the issues described in "—Section 754 Election" and "—Disposition of LP Units—Allocations Between Transferors and Transferees," allocations of income, gain, loss or deduction under our partnership agreement will be given substantial economic effect.

        Treatment of Securities Loans.    A unitholder whose LP Units are the subject of a securities loan (for example, a loan to a "short seller" to cover a short sale of LP Units) may be treated as having disposed of those LP Units. If so, such unitholder would no longer be treated for tax purposes as a partner with respect to those LP Units during the period of the loan and may recognize gain or loss from the disposition. As a result, during this period (i) any of our income, gain, loss or deduction allocated to those LP Units would not be reportable by the lending unitholder and (ii) any cash distributions received by the unitholder as to those LP Units may be treated as ordinary taxable income.

        Due to a lack of controlling authority, Vinson & Elkins L.L.P. has not rendered an opinion regarding the tax treatment of a unitholder that enters into a securities loan with respect to its LP Units. Unitholders desiring to assure their status as partners and avoid the risk of income recognition from a loan of their LP Units are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing and lending their LP Units. The IRS has announced that it is studying issues relating to the tax treatment of short sales of partnership interests. Please read "—Disposition of LP Units—Recognition of Gain or Loss."

        Tax Rates.    Under current law, the highest marginal federal income tax rates for individuals applicable to ordinary income and long-term capital gains (generally, gains from the sale or exchange of certain investment assets held for more than one year) are 39.6% and 20%, respectively. These rates are subject to change by new legislation at any time.

        In addition, a 3.8% net investment income tax applies to certain net investment income earned by individuals, estates, and trusts. For these purposes, net investment income generally includes a unitholder's allocable share of our income and gain realized by a unitholder from a sale of LP Units. In the case of an individual, the tax will be imposed on the lesser of (i) the unitholder's net investment income from all investments, or (ii) the amount by which the unitholder's modified adjusted gross income exceeds $250,000 (if the unitholder is married and filing jointly or a surviving spouse), $125,000 (if married filing separately) or $200,000 (if the unitholder is unmarried or in any other case). In the case of an estate or trust, the tax will be imposed on the lesser of (i) undistributed net investment income, or (ii) the excess adjusted gross income over the dollar amount at which the highest income tax bracket applicable to an estate or trust begins.

        Section 754 Election.    We have made the election permitted by Section 754 of the Code that permits us to adjust the tax bases in our assets as to specific purchasers of our LP Units under Section 743(b) of the Code. That election is irrevocable without the consent of the IRS. The Section 743(b) adjustment separately applies to each purchaser of LP Units based upon the values and bases of our assets at the time of the relevant LP Unit purchase, and the adjustment will reflect the purchase price paid. The Section 743(b) adjustment does not apply to a person who purchases LP Units directly from us.

        Under our partnership agreement, we are authorized to take a position to preserve the uniformity of LP Units even if that position is not consistent with these or any other Treasury Regulations. A literal application of Treasury Regulations governing a Section 743(b) adjustment attributable to properties depreciable under Section 167 of the Code may give rise to differences in the taxation of unitholders purchasing units from us and unitholders purchasing from other unitholders. If we have any such properties, we intend to adopt methods employed by other publicly traded partnerships to preserve the uniformity of units, even if inconsistent with existing Treasury Regulations, and Vinson & Elkins L.L.P. has not opined on the validity of this approach. Please read "—Uniformity of LP Units."

        The IRS may challenge our position with respect to depreciating or amortizing the Section 743(b) adjustment we take to preserve the uniformity of LP Units due to the lack of controlling authority. Because a unitholder's tax basis in its LP Units is reduced by its share of our items of deduction or loss, any position we take that understates deductions will overstate a unitholder's basis in its LP Units,

24


Table of Contents

and may cause the unitholder to understate gain or overstate loss on any sale of such LP Units. Please read "—Disposition of LP Units—Recognition of Gain or Loss." If a challenge to such treatment were sustained, the gain from the sale of LP Units may be increased without the benefit of additional deductions.

        The calculations involved in the Section 754 election are complex and will be made on the basis of assumptions as to the value of our assets and other matters. The IRS could seek to reallocate some or all of any Section 743(b) adjustment we allocated to our assets subject to depreciation to goodwill or nondepreciable assets. Goodwill, as an intangible asset, is generally amortizable over a longer period of time or under a less accelerated method than our tangible assets. We cannot assure any unitholder that the determinations we make will not be successfully challenged by the IRS or that the resulting deductions will not be reduced or disallowed altogether. Should the IRS require a different tax basis adjustment to be made, and should, in our opinion, the expense of compliance exceed the benefit of the election, we may seek permission from the IRS to revoke our Section 754 election. If permission is granted, a subsequent purchaser of LP Units may be allocated more income than it would have been allocated had the election not been revoked.

Tax Treatment of Operations

        Accounting Method and Taxable Year.    We use the year ending December 31 as our taxable year and the accrual method of accounting for federal income tax purposes. Each unitholder will be required to include in its tax return its share of our income, gain, loss and deduction for each taxable year ending within or with its taxable year. In addition, a unitholder who has a taxable year ending on a date other than December 31 and who disposes of all of its LP Units following the close of our taxable year but before the close of its taxable year must include its share of our income, gain, loss and deduction in income for its taxable year, with the result that it will be required to include in income for its taxable year its share of more than one year of our income, gain, loss and deduction. Please read "—Disposition of LP Units—Allocations Between Transferors and Transferees."

        Tax Basis, Depreciation and Amortization.    The tax bases of our assets will be used for purposes of computing depreciation and cost recovery deductions and, ultimately, gain or loss on the disposition of those assets. If we dispose of depreciable property by sale, foreclosure or otherwise, all or a portion of any gain, determined by reference to the amount of depreciation and depletion deductions previously taken may be subject to the recapture rules and taxed as ordinary income rather than capital gain. Similarly, a unitholder who has taken cost recovery or depreciation deductions with respect to property we own will likely be required to recapture some or all of those deductions as ordinary income upon a sale of its interest in us. Please read "—Tax Consequences of LP Unit Ownership—Allocation of Income, Gain, Loss and Deduction" and "—Disposition of LP Units—Recognition of Gain or Loss."

        The costs we incur in offering and selling our LP Units (called "syndication expenses") must be capitalized and cannot be deducted currently, ratably or upon our termination. While there are uncertainties regarding the classification of costs as organization expenses, which may be amortized by us, and as syndication expenses, which may not be amortized by us, the underwriting discounts and commissions we incur will be treated as syndication expenses. Please read "Disposition of LP Units—Recognition of Gain or Loss."

        Valuation and Tax Basis of Our Properties.    The federal income tax consequences of the ownership and disposition of LP Units will depend in part on our estimates of the relative fair market values and the tax bases of our assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we will make many of the relative fair market value estimates ourselves. These estimates and determinations of tax basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss or deduction previously reported by unitholders could change, and unitholders could be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.

Table of Contents

Disposition of LP Units

        Recognition of Gain or Loss.    A unitholder will be required to recognize gain or loss on a sale of LP Units equal to the difference between the unitholder's amount realized and tax basis in the LP Units sold. A unitholder's amount realized will equal the sum of the cash and the fair market value of other property it receives plus its share of our liabilities with respect to such LP Units sold. Because the amount realized includes a unitholder's share of our liabilities, the gain recognized on the sale of LP Units could result in a tax liability in excess of any cash received from the sale.

        Except as noted below, gain or loss recognized by a unitholder on the sale or exchange of an LP Unit held for more than one year generally will be taxable as long-term capital gain or loss. However, gain or loss recognized on the disposition of LP Units will be separately computed and taxed as ordinary income or loss under Section 751 of the Code to the extent attributable to Section 751 Assets, such as depreciation or depletion recapture and our "inventory items," regardless of whether such inventory item is substantially appreciated in value. Ordinary income attributable to Section 751 Assets may exceed net taxable gain realized on the sale of an LP Unit and may be recognized even if there is a net taxable loss realized on the sale of an LP Unit. Thus, a unitholder may recognize both ordinary income and capital gain or loss upon a sale of LP Units. Net capital loss may offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year.

        For purposes of calculating gain or loss on the sale of units, the unitholder's adjusted tax basis will be adjusted by its allocable share of our income or loss in respect of its units for the year of the sale. Furthermore, as described above, the IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all of those interests. Upon a sale or other disposition of less than all of those interests, a portion of that tax basis must be allocated to the interests sold using an "equitable apportionment" method, which generally means that the tax basis allocated to the interest sold equals an amount that bears the same relation to the partner's tax basis in its entire interest in the partnership as the value of the interest sold bears to the value of the partner's entire interest in the partnership.

        Treasury Regulations under Section 1223 of the Code allow a selling unitholder who can identify LP Units transferred with an ascertainable holding period to elect to use the actual holding period of the LP Units transferred. Thus, according to the ruling discussed above, a unitholder will be unable to select high or low basis LP Units to sell as would be the case with corporate stock, but, according to the Treasury Regulations, it may designate specific LP Units sold for purposes of determining the holding period of LP Units transferred. A unitholder electing to use the actual holding period of LP Units transferred must consistently use that identification method for all subsequent sales or exchanges of our LP Units. A unitholder considering the purchase of additional LP Units or a sale of LP Units purchased in separate transactions is urged to consult its tax advisor as to the possible consequences of this ruling and application of the Treasury Regulations.

        Specific provisions of the Code affect the taxation of some financial products and securities, including partnership interests, by treating a taxpayer as having sold an "appreciated" financial positions, including a partnership interest with respect to which gain would be recognized if it were sold, assigned or terminated at its fair market value, if the taxpayer or related persons enter(s) into:

        Moreover, if a taxpayer has previously entered into a short sale, an offsetting notional principal contract or a futures or forward contract with respect to the partnership interest, the taxpayer will be

26


Table of Contents

treated as having sold that position if the taxpayer or a related person then acquires the partnership interest or substantially identical property. The Secretary of the Treasury is also authorized to issue Treasury Regulations that treat a taxpayer that enters into transactions or positions that have substantially the same effect as the preceding transactions as having constructively sold the financial position.

        Allocations Between Transferors and Transferees.    In general, our taxable income or loss will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the unitholders in proportion to the number of LP Units owned by each of them as of the opening of the applicable exchange on the first business day of the month (the "Allocation Date"). However, gain or loss realized on a sale or other disposition of our assets or, in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction will be allocated among the unitholders on the Allocation Date in the month in which such income, gain, loss or deduction is recognized. As a result, a unitholder transferring LP Units may be allocated income, gain, loss and deduction realized after the date of transfer.

        Although simplifying conventions are contemplated by the Code and most publicly traded partnerships use similar simplifying conventions, the use of this method may not be permitted under existing Treasury Regulations. Recently, however, the Department of the Treasury and the IRS issued proposed Treasury Regulations that provide a safe harbor pursuant to which a publicly traded partnership may use a similar monthly simplifying convention to allocate tax items among transferor and transferee unitholders, although such tax items must be prorated on a daily basis. Nonetheless, the proposed regulations do not specifically authorize the use of the proration method we have adopted. Accordingly, Vinson & Elkins L.L.P. is unable to opine on the validity of this method of allocating income and deductions between transferee and transferor unitholders. If this method is not allowed under the Treasury Regulations, or only applies to transfers of less than all of the unitholder's interest, our taxable income or losses might be reallocated among the unitholders. We are authorized to revise our method of allocation between transferee and transferor unitholders, as well as among unitholders whose interests vary during a taxable year, to conform to a method permitted under future Treasury Regulations.

        A unitholder who disposes of LP Units prior to the record date set for a cash distribution for that quarter will be allocated items of our income, gain, loss and deduction attributable to the month of disposition but will not be entitled to receive a cash distribution for that period.

        Notification Requirements.    A unitholder who sells or purchases any of its LP Units is generally required to notify us in writing of that transaction within 30 days after the transaction (or, if earlier, January 15 of the year following the transaction in the case of a seller). Upon receiving such notifications, we are required to notify the IRS of that transaction and to furnish specified information to the transferor and transferee. Failure to notify us of a transfer of LP Units may, in some cases, lead to the imposition of penalties. However, these reporting requirements do not apply to a sale by an individual who is a citizen of the United States and who effects the sale through a broker who will satisfy such requirements.

        Constructive Termination.    We will be considered to have "constructively" terminated as a partnership for federal income tax purposes upon the sale or exchange of 50% or more of the total interests in our capital and profits within a twelve-month period. For purposes of measuring whether the 50% threshold is reached, multiple sales of the same LP Unit are counted only once. A constructive termination results in the closing of our taxable year for all unitholders. In the case of a unitholder reporting on a taxable year other than the calendar year, the closing of our taxable year may result in more than twelve months of our taxable income or loss being includable in such unitholder's taxable income for the year of termination.

27


Table of Contents

        A constructive termination occurring on a date other than December 31 would result in us filing two tax returns for one fiscal year thereby increasing our administration and tax costs. However, pursuant to an IRS relief procedure, the IRS may allow a constructively terminated partnership to provide a single Schedule K-1 for the calendar year in which a termination occurs. We would be required to make new tax elections after a termination, including a new election under Section 754 of the Code, and a termination would result in a deferral of our deductions for depreciation. A termination could also result in penalties if we were unable to determine that the termination had occurred. Moreover, a termination may either accelerate the application of, or subject us to, any tax legislation enacted before the termination that would not otherwise have been applied to us as a continuing as opposed to a terminating partnership.

Uniformity of LP Units

        Because we cannot match transferors and transferees of LP Units and for other reasons, we must maintain uniformity of the economic and tax characteristics of the LP Units to a purchaser of these LP Units. In the absence of uniformity, we may be unable to completely comply with a number of federal income tax requirements. Any non-uniformity could have a negative impact on the value of the LP Units. Please read "—Tax Consequences of LP Unit Ownership—Section 754 Election."

        Our partnership agreement permits our general partner to take positions in filing our tax returns that preserve the uniformity of our LP Units. These positions may include reducing for some unitholders the depreciation, amortization or loss deductions to which a unitholder would otherwise be entitled or reporting a slower amortization of Section 743(b) adjustments for some unitholders than that to which they would otherwise be entitled. Vinson & Elkins L.L.P. is unable to opine as to the validity of such filing positions. A unitholder's basis in LP Units is reduced by its share of our deductions (whether or not such deductions were claimed on an individual income tax return) so that any position that we take that understates deductions will overstate the unitholder's basis in its LP Units, and may cause the unitholder to understate gain or overstate loss on any sale of such LP Units. Please read "—Disposition of LP Units—Recognition of Gain or Loss" above and "—Tax Consequences of LP Unit Ownership—Section 754 Election" above. The IRS may challenge one or more of any positions we take to preserve the uniformity of LP Units. If such a challenge were sustained, the uniformity of LP Units might be affected, and, under some circumstances, the gain from the sale of LP Units might be increased without the benefit of additional deductions.

Tax-Exempt Organizations and Other Investors

        Ownership of LP Units by employee benefit plans and other tax-exempt organizations as well as by non-resident alien individuals, non-U.S. corporations and other non-U.S. persons (collectively, "Non-U.S. Unitholders") raises issues unique to those investors and, as described below, may have substantial adverse tax consequences to them. Prospective unitholders that are tax-exempt entities or Non-U.S. Unitholders should consult their tax advisors before investing in our LP Units. Employee benefit plans and most other tax-exempt organizations, including IRAs and other retirement plans, are subject to federal income tax on unrelated business taxable income. Virtually all of our income will be unrelated business taxable income and will be taxable to a tax-exempt unitholder.

        Non-U.S. Unitholders are taxed by the United States on income effectively connected with the conduct of a U.S. trade or business ("effectively connected income") and on certain types of U.S.-source non-effectively connected income (such as dividends), and unless exempted or further limited by an income tax treaty, will be considered to be engaged in business in the United States because of their ownership of our LP Units. Furthermore, it is probable that they will be deemed to conduct such activities through permanent establishments in the United States within the meaning of applicable tax treaties. Consequently, they will be required to file federal tax returns to report their share of our income, gain, loss or deduction and pay federal income tax on their share of our net income or gain in

28


Table of Contents

a manner similar to a taxable U.S. unitholder. Moreover, under rules applicable to publicly traded partnerships, distributions to Non-U.S. Unitholders are subject to withholding at the highest applicable effective tax rate. Each Non-U.S. Unitholder must obtain a taxpayer identification number from the IRS and submit that number to our transfer agent on a Form W-8BEN, W-8BEN-E or applicable substitute form in order to obtain credit for these withholding taxes.

        In addition, because a Non-U.S. Unitholder classified as a corporation will be treated as engaged in a U.S. trade or business, that corporation may be subject to the U. S. branch profits tax at a rate of 30%, in addition to regular federal income tax, on its share of our income and gain, as adjusted for changes in the foreign corporation's "U.S. net equity," to the extent reflected in the corporation's effectively connected earnings and profits. That tax may be reduced or eliminated by an income tax treaty between the United States and the country in which the foreign corporate unitholder is a "qualified resident." In addition, this type of unitholder is subject to special information reporting requirements under Section 6038C of the Code.

        A Non-U.S. Unitholder who sells or otherwise disposes of an LP Unit will be subject to federal income tax on gain realized from the sale or disposition of that LP Unit to the extent the gain is effectively connected with a U.S. trade or business of the Non-U.S. Unitholder. Under a ruling published by the IRS, interpreting the scope of "effectively connected income," gain recognized by a non-U.S. person from the sale of its interest in a partnership that is engaged in a trade or business in the United States will be considered to be effectively connected with a U.S. trade or business. Thus, part or all of a Non-U.S. Unitholder's gain from the sale or other disposition of its units may be treated as effectively connected with a unitholder's indirect U.S. trade or business constituted by its investment in us. Moreover, under the Foreign Investment in Real Property Tax Act, a Non-U.S. Unitholder generally will be subject to federal income tax upon the sale or disposition of an LP Unit if (i) it owned (directly or constructively applying certain attribution rules) more than 5% of our LP Units at any time during the five-year period ending on the date of such disposition and (ii) 50% or more of the fair market value of our worldwide real property interests and our other assets used or held for use in a trade or business consisted of U.S. real property interests which include U.S. real estate (including land, improvements, and certain associated personal property) and interests in certain entities holding U.S. real estate at any time during the shorter of the period during which such unitholder held the LP Units or the 5-year period ending on the date of disposition. Currently, more than 50% of our assets consist of U.S. real property interests and we do not expect that to change in the foreseeable future. Therefore, Non-U.S. Unitholders may be subject to federal income tax on gain from the sale or disposition of their LP Units.

Administrative Matters

        Information Returns and Audit Procedures.    We intend to furnish to each unitholder, within 90 days after the close of each taxable year, specific tax information, including a Schedule K-1, which describes its share of our income, gain, loss and deduction for our preceding taxable year. In preparing this information, which will not be reviewed by counsel, we will take various accounting and reporting positions, some of which have been mentioned earlier, to determine each unitholder's share of income, gain, loss and deduction. We cannot assure our unitholders that those positions will yield a result that conforms to the requirements of the Code, Treasury Regulations or administrative interpretations of the IRS.

        The IRS may audit our federal income tax information returns. Neither we nor Vinson & Elkins L.L.P. can assure prospective unitholders that the IRS will not successfully challenge the positions we adopt, and such a challenge could adversely affect the value of the LP Units. The IRS may audit our federal income tax information returns. Adjustments resulting from an IRS audit may require each unitholder to adjust a prior year's tax liability, and possibly may result in an audit of its own return. Any audit of a unitholder's return could result in adjustments unrelated to our returns.

29


Table of Contents

        Publicly traded partnerships generally are treated as entities separate from their owners for purposes of federal income tax audits, judicial review of administrative adjustments by the IRS and tax settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined in a partnership proceeding rather than in separate proceedings of the partners. The Code requires that one partner be designated as the "Tax Matters Partner" for these purposes, and our partnership agreement designates our general partner.

        The Tax Matters Partner has made and will make some elections on our behalf and on behalf of unitholders. The Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against unitholders for items in our returns. The Tax Matters Partner may bind a unitholder with less than a 1% profits interest in us to a settlement with the IRS unless that unitholder elects, by filing a statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the unitholders are bound, of a final partnership administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any unitholder having at least a 1% interest in profits or by any group of unitholders having in the aggregate at least a 5% interest in profits. However, only one action for judicial review may go forward, and each unitholder with an interest in the outcome may participate in that action.

        A unitholder must file a statement with the IRS identifying the treatment of any item on its federal income tax return that is not consistent with the treatment of the item on our return. Intentional or negligent disregard of this consistency requirement may subject a unitholder to substantial penalties.

        Nominee Reporting.    Persons who hold an interest in us as a nominee for another person are required to furnish to us:

        Brokers and financial institutions are required to furnish additional information, including whether they are U.S. persons and specific information on LP Units they acquire, hold or transfer for their own account. A penalty of $100 per failure, up to a maximum of $1.5 million per calendar year, is imposed by the Code for failure to report that information to us. The nominee is required to supply the beneficial owner of the LP Units with the information furnished to us.

        Accuracy-Related Penalties.    Certain penalties may be imposed on taxpayers as a result of an underpayment of tax that is attributable to one or more specified causes, including negligence or disregard of rules or regulations, substantial understatements of income tax and substantial valuation misstatements. No penalty will be imposed, however, for any portion of any such underpayment if it is shown that there was a reasonable cause for the underpayment of that portion and that the taxpayer acted in good faith regarding the underpayment of that portion. Penalties may also be imposed for

30

engaging in transactions without economic substance. We do not anticipate engaging in transactions without economic substance or otherwise participating in transactions that would subject our unitholders to accuracy-related penalties.

State, Local and Other Tax Considerations

        In addition to federal income taxes, unitholders will be subject to other taxes, including state and local income taxes, unincorporated business taxes, and estate, inheritance or intangibles taxes that may be imposed by the various jurisdictions in which we conduct business or own property or in which the unitholder is a resident. We currently do business or own property in more than 30 states, most of which impose income taxes. The Partnership also owns property and conducts business in Puerto Rico, St. Lucia and Grand Bahama. Under current law, unitholders are not required to file a tax return or pay taxes in Puerto Rico, St. Lucia or Grand Bahama. We may own property or do business in other states or foreign jurisdictions in the future that impose income or similar taxes on nonresident individuals. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on its investment in us. Unitholders may not be required to file a return and pay taxes in some states because its income from that state falls below the filing and payment requirement. Unitholders will be required, however, to file state income tax returns and to pay state income taxes in many of these states in which we do business or own property, and unitholders may be subject to penalties for failure to comply with those requirements. Some of the states may require us, or we may elect, to withhold a percentage of income from amounts to be distributed to a unitholder who is not a resident of the state. Withholding, the amount of which may be greater or less than a particular unitholder's income tax liability to the state, generally does not relieve a nonresident unitholder from the obligation to file an income tax return.

        It is the responsibility of each unitholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, of its investment in us. We strongly recommend that each prospective unitholder consult, and depend on, its own tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each unitholder to file all state, local, and non-U.S., as well as U.S. federal tax returns that may be required of it. Vinson & Elkins L.L.P. has not rendered an opinion on the state, local, alternative minimum tax or non-U.S. tax consequences of an investment in us.

Item 17.    Undertakings.

        The undersigned registrant hereby undertakes:

        (1)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

II-1


Table of Contents

provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

        (2)   That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (3)   To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

        (4)   That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

II-2


Table of Contents

        (5)   That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

        (6)   That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        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 SEC such indemnification is against public policy as expressed in the Securities Act of 1933 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 Securities Act of 1933 and will be governed by the final adjudication of such issue.
