RECITALS

A. The General Partner is the general partner of the Partnership and holds (i) the General Partner Interest (as defined in the Current Partnership Agreement (as defined below)) in the Partnership, and (ii) limited partner interests in the Partnership defined in the Current Partnership Agreement as “Common Units.”

B. The General Partner is also the holder of certain limited partner interests in the Partnership defined in the Current Partnership Agreement as “Incentive Distribution Rights” (“IDRs”). The class of IDRs described in the Current Partnership Agreement and currently held by the General Partner are referred to herein as the “Old IDRs.”

C. The Partnership has agreed to repurchase, and the General Partner has agreed to transfer and assign to the Partnership, all of the Old IDRs held by it for cancellation in exchange for (i) the issuance by the Partnership to the General Partner of a new class of IDRs to be issued by the Partnership under the Revised Partnership Agreement (as defined below), having the rights, preferences, privileges and restrictions set forth therein (the “New IDRs”) and (ii) the issuance by the Partnership to the General Partner of a promissory note in the principal amount of $200 million plus the First Quarter Distribution Adjustment and substantially in the form attached hereto as Exhibit 2 (the “Note”), and the Partnership has agreed to issue the New IDRs and issue the Note to the General Partner as consideration for the transfer and assignment of the Old IDRs to the Partnership.

D. The parties hereto have agreed to amend and restate the Second Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of July 20, 2004, as amended by Amendment No. 1 thereto, dated January 23, 2008, as further amended by Amendment No. 2 thereto, effective as of November 18, 2008 (as amended, the “Current Partnership Agreement”), so as to reflect the cancellation of the Old IDRs and the authorization of issuance of the New IDRs (such amended and restated agreement being referred to as the “Revised Partnership Agreement”).

E. The execution and adoption of the Revised Partnership Agreement, the repurchase by the Partnership, and the transfer and assignment by the General Partner to the Partnership, of the Old IDRs, the issuance by the Partnership of the New IDRs, and the issuance by the Partnership of the Note, as described above (collectively, the “Transactions”), are conditioned on each other and shall occur simultaneously.

F. The parties hereto have agreed that distributions made by the Partnership to the Partners for the entire fiscal quarter in which the Effective Time occurs shall be made under the terms of the Revised Partnership Agreement, notwithstanding that the Effective Time (and the

repurchase of the Old IDR’s) is not occurring on the first day of such fiscal quarter. In order to compensate the General Partner for the distributions that it would have received with respect to the Old IDRs for the period from the beginning of the fiscal quarter in which the Effective Time occurs until the Effective Time, the Partnership has agreed to the First Quarter Distribution Adjustment.

NOW, THEREFORE, in consideration of their mutual undertakings and agreements hereunder, the parties undertake and agree as follows:
