WHEREAS, in accordance with past practice, Executive shall continue to be an employee of, and receive benefits through, Buckeye Pipe Line Services Company (“Services”).  For purposes of this Agreement, Executive’s employment by, and provision of services to, Services shall be deemed the employment by, and provision of services to, the Partnership; and

WHEREAS, in consideration of Executive’s continued employment by the Partnership or one or more Subsidiaries or Affiliates of the Partnership and the contribution of Class B Units in MainLine L.P., a Delaware limited partnership (“MainLine”), to the Partnership pursuant to the Contribution Agreement, the Partnership shall issue to the Executive, 426,000 Management Units in the Partnership to the Executive.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement, intending to be legally bound, hereby agree as follows:

1.             Issuance of Executive Units.

(a)           Upon the closing of the transactions contemplated in the Contribution Agreement the Partnership will issue 678,623 Common Units to the Trust and 426,000 Management Units to Executive, in consideration of the contributions set forth in the Contribution Agreement and Executive’s continued performance as an employee of the Partnership or one or more Subsidiaries or Affiliates of the Partnership.  The Management Units acquired pursuant to this Section 1(a) shall be subject to the vesting schedule set forth in Section 2 below.

(b)           In connection with the acquisition of the Executive Units hereunder, Executive represents and warrants to the Partnership:

(i)            The Executive Units to be acquired by Executive and the Trust pursuant to this Agreement will be acquired for Executive’s own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, or any

applicable state securities laws, and the Executive Units will not be disposed of in contravention of the Securities Act or any applicable state securities laws.

(ii)           Executive is an executive officer of the Partnership or a Subsidiary or Affiliate thereof, is sophisticated in financial matters and is able to evaluate the risks and benefits of decisions respecting the investment in the Executive Units.

(iii)          Executive and the Trust are able to bear the economic risk of his investment in the Executive Units for an indefinite period of time because the Executive Units have not been registered under the Securities Act, and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available.

(iv)          Executive has had an opportunity to ask questions and receive answers concerning the terms and conditions of the offering of the Executive Units and has had full access to such other information concerning the Partnership as he, she or it has requested.

(v)           Executive has received and read a copy of the Partnership Agreement.  This Agreement, the Partnership Agreement, the Contribution Agreement and each of the other agreements contemplated hereby and thereby constitute the legal, valid and binding obligation of Executive, enforceable in accordance with their terms, and the execution, delivery and performance of this Agreement, the Partnership Agreement, the Contribution Agreement and the other agreements contemplated hereby and thereby by Executive do not and will not conflict with, violate or cause a breach of any agreement, contract or instrument to which Executive is a party or any judgment, order or decree to which Executive is subject or create any conflict of interest with the Partnership, any Affiliate thereof, or its or their present or former customers.

(vi)          Executive is a resident of the Commonwealth of Pennsylvania and the Trust is established under the laws of the Commonwealth of Pennsylvania.

(c)           As an inducement to the Partnership to issue the Common Units to the Trust and the Management Units to Executive, and as a condition thereto, Executive and the Trust acknowledge and agree that:

(i)            neither the issuance of the Executive Units to Executive nor any provision contained herein shall entitle Executive to remain in the employment of the Partnership and its Subsidiaries or Affiliates or affect the right of the Partnership to terminate Executive’s employment at any time;

(ii)           each has read and understands Exhibit A attached hereto, setting forth certain risks associated with Executive’s acquisition of the Executive Units; and

(iii)          the Trustees shall not amend the Trust Agreement in a manner that requires any court approval for any party to exercise its rights under this Agreement or in

2

a manner that takes away the Trustees’ ability to bind the Trust to any contract or agreement.

(d)           Upon the Trust’s and Executive’s receipt of Executive Units, Executive and the Trust will execute and deliver to the Partnership a joinder agreement to the Partnership Agreement in the form of Exhibit B attached hereto.

2.             Vesting of Management Units.

(a)           70% of the Management Units shall be vested upon the date hereof.  The remaining 30% of the Management Units will become vested in accordance with the following schedule, if as of each such date the Executive is still employed by the Partnership or any of its Subsidiaries or Affiliates:

If Executive ceases to be employed by the Partnership or any of its Subsidiaries or Affiliates at any time after the date hereof all vesting shall cease.  If Executive ceases to be employed by the Partnership or any of its Subsidiaries at or Affiliates other than on a date set forth above, then a portion of the 10% subject to vesting on the next May 4th will vest, determined on a pro-rata basis according to the number of days that have elapsed since the prior anniversary date set forth in the table above immediately preceding the date of termination of Executive’s employment.

(b)           Upon the occurrence of a Sale of the Partnership, all unvested Management Units, other than any unvested Management Units with respect to which a Repurchase Notice or Supplemental Repurchase Notice has been delivered to Executive if Executive is no longer employed by the Partnership or any of its Subsidiaries or Affiliates at such time, shall become vested at the time (and immediately prior to the consummation) of such event.

(c)           Common Units and the Management Units which have become vested pursuant to the above schedules are referred to herein as “Vested Units,” and all other Executive Units are referred to herein as “Unvested Units.”

3.             Forfeiture.  In the event Executive ceases to be employed by the Partnership or any of its Subsidiaries or Affiliates for any reason (a “Termination”), any unvested Management Units shall be forfeited.
