                      AMENDMENT NO. 1 TO GUARANTY AGREEMENT

      THIS AMENDMENT NO. 1 TO GUARANTY AGREEMENT (this "AMENDMENT") is entered
into as of December 15, 2004 by and among BUCKEYE PIPE LINE SERVICES COMPANY, a
Pennsylvania corporation (the "GUARANTOR"), and each of the undersigned holders
of Notes (as defined below).

                                    RECITALS

      A. The Buckeye Pipe Line Services Company Employee Stock Ownership Plan
Trust (the "ESOP TRUST") and the undersigned holders of Notes entered into a
Note Agreement dated as of May 4, 2004 (as amended, restated, supplemented or
otherwise modified from time to time, the "NOTE AGREEMENT"), pursuant to which
the ESOP Trust issued and sold to such holders the ESOP Trust's 3.60% Senior
Secured Notes due March 28, 2011, in the aggregate principal amount of
$44,133,600 (together with any notes issued in substitution or exchange therefor
pursuant to the Note Agreement, the "NOTES").

      B. In connection with the issuance and sale of the Notes pursuant to the
Note Agreement, the Guarantor entered into a Guaranty Agreement dated as of May
4, 2004 (as amended, restated, supplemented or otherwise modified from time to
time, including by this Amendment, the "GUARANTY"), in favor of the holders from
time to time of the Notes. Capitalized terms used and not otherwise defined in
this Amendment shall have the respective meanings ascribed to them in the
Guaranty.

      C. The undersigned holders of Notes have been advised that the Manager,
the Master Partnership and certain of their respective Affiliates desire to
effect a restructuring of certain contractual rights and obligations and other
arrangements, which will include the following: (i) the Manager will transfer
its general partner interests in the Master Partnership and each of the
Operating Companies that is a limited partnership to Buckeye GP LLC, a newly
formed Delaware limited liability company and wholly owned subsidiary of the
Manager (the "NEW MANAGER"); (ii) the New Manager will become the new general
partner of the Master Partnership and each of such Operating Companies and will
assume all of the rights and obligations of the Manager as general partner of
the Master Partnership and each of such Operating Companies; (iii) the Services
Agreement (as defined in the Agreement before giving effect to this Amendment)
will be terminated and a new services agreement will be entered into by and
among the Master Partnership, certain of the Operating Companies and the
Services Company; (iv) the Manager will assign all of its contractual rights and
obligations, other than those under the Incentive Compensation Agreement, to the
New Manager, and the New Manager will assume all such rights and obligations;
(v) BMC and the Manager will merge with and into Glenmoor, which will
immediately thereafter change its name to MainLine Sub LLC and will thereafter
directly own all of the issued and outstanding equity interests in the New
Manager; and (vi) certain additional actions necessary or advisable in order to
effect the foregoing will be taken.

<PAGE>

      D. To facilitate the above-described restructuring, the ESOP Trustee and
the Guarantor have requested that (i) the Guaranty be amended and (ii) the
holders of Notes consent to certain elements of such restructuring, in each case
as provided hereinbelow.

      E. The undersigned holders of Notes are willing to agree to such
amendments and to provide such consent, upon and subject to the terms and
conditions set forth herein.

      NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree, subject to the terms and
conditions set forth herein, and, in the case of the undersigned holders of
Notes, in reliance on the representations and warranties of the Guarantor
contained herein, as follows:

      SECTION 1. AMENDMENTS TO GUARANTY. Effective as of the Amendment Effective

            (a) Amendments to Section 1 (Definitions).

                  (i) Section 1 of the Guaranty is amended by deleting in their
            entirety the definitions of "BMC Expense Reimbursement Agreement",
            "Guarantor Security Agreement" and "Reimbursement Security
            Agreements". From and after the Amendment Effective Date, all
            references to any of such terms in the Agreement or in any of the
            other Note Documents shall have no further force or effect.

                  (ii) Section 1 of the Guaranty is further amended by adding
            the following new definition in its appropriate alphabetical
            position:

                        " "EXECUTIVE EMPLOYMENT AGREEMENT" shall mean the
                  Executive Employment Agreement, dated as of December 15, 2004,
                  by and among the Manager, MainLine and the Guarantor, as
                  amended, restated, supplemented or otherwise modified from
                  time to time."

            (b) Amendment to Section 5.9 (Limitation on Transactions with
      Affiliates). Section 5.9 of the Guaranty is amended by deleting it in its
      entirety and replacing it with the following:

                  "5.9 LIMITATION ON TRANSACTIONS WITH AFFILIATES. Except as
            specifically contemplated by the Note Documents, the ESOP Documents,
            the Services Agreement and the Executive Employment Agreement, the
            Guarantor will not, directly or indirectly, enter into or suffer to
            exist any transaction (including, without limitation, the lease,
            purchase, sale or exchange of property or the rendering of service)
            with any of its Affiliates or the ESOP Trustee, MainLine, the
            Manager or any of their respective Affiliates unless the terms of
            such transaction are no less favorable to the Guarantor than could
            be obtained in a comparable arm's length transaction with a Person
            that is not an Affiliate of the Guarantor, the ESOP Trustee,
            MainLine, the Manager or any of their respective Affiliates."

            DOCUMENTS. Without the express prior written consent of the Required
            Holder(s), the Guarantor will not amend, modify, change or
            terminate, or consent or agree to any amendment, modification,
            change to or termination of, any of the terms of the Services
            Agreement or the Executive Employment Agreement. Without the express
            prior written consent of the Required Holder(s), the Guarantor will
            not amend, modify or change in a manner which is adverse to the
            interests of the holders of the Notes or in any other material
            respect, or consent or agree to any material amendment, modification
            or change, or any amendment, modification or change which is adverse
            to the interests of the holders of the Notes, to any of the terms of
            the articles of incorporation, bylaws or other corporate
            organizational or governance documents of the Guarantor. Promptly
            after the execution and delivery of any amendment, modification or
            change to any document described above, the Guarantor will provide a
            copy thereof to each Significant Holder."

                  (d) Amendments to Section 6.1 (Events of Default). Section 6.1
      of the Guaranty is amended by deleting it in its entirety and replacing it

            under any such agreement shall occur and be continuing) and the
            effect of such failure or other event is to cause, or to permit the
            holder or holders of such obligation (or a trustee on behalf of such
            holder or holders) to cause, such obligation to become due (or to be
            repurchased by the Guarantor, the Master Partnership or any

            contained in any agreement under which any such obligation is
            created (or if any other event thereunder or under any such
            agreement shall occur and be continuing) and the effect of such
            default, failure or other event is to cause such obligation to
            become due (or to be repurchased by the Manager) prior to any stated
            maturity, provided that the aggregate amount of all obligations as
            to which such default, failure or other event causing acceleration
