     (a) The execution, delivery and performance by the Borrower of this Amendment are within the Borrower’s legal powers, have been duly authorized by all necessary partnership action and do not (i) contravene the Borrower Partnership Agreement, (ii) violate any applicable Governmental Rule, the violation of which could reasonably be expected to have a Material Adverse Effect, (iii) conflict with or result in the breach of, or constitute a default under, any loan agreement, indenture, mortgage, deed of trust or lease, or any other contract or instrument binding on or affecting the Borrower or any Subsidiary or any of their respective properties, the conflict, breach or default of which could reasonably be expected to have a Material Adverse Effect, or (iv) result in or require the creation or imposition of any Lien upon or with respect to any of the properties of the Borrower, other than Liens permitted by the Credit Agreement.

     (b) No Governmental Action is required for the due execution, delivery or performance by the Borrower of this Amendment.

     (c) Assuming due execution and delivery by the Majority Banks and the Administrative Agent, this Amendment constitutes legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, moratorium, reorganization or other similar laws affecting creditors’ rights generally or by general principles of equity (regardless of whether such enforceability is considered in any proceeding in law or in equity).

     (d) The execution, delivery and performance of this Amendment do not adversely affect the enforceability of any Lien of the Security Documents.

     (e) The quarterly and annual financial statements most recently delivered to the Banks pursuant to Sections 5.01(c) and (d) of the Credit Agreement fairly present the Consolidated financial condition of the Borrower and its Subsidiaries as of the respective dates thereof and the Consolidated results of the operations of the Borrower and its Subsidiaries for the respective fiscal periods ended on such dates, all in accordance with GAAP applied on a consistent basis (subject to normal year-end audit adjustments and the absence of footnotes in the case of the quarterly financial statements).

December 31, 2004, no Material Adverse Effect has occurred. The Borrower and its Subsidiaries have no material contingent liabilities except as disclosed in such financial statements or the notes thereto.

     (f) There is no pending or, to the knowledge of the Borrower, threatened action or proceeding affecting the Borrower or any Subsidiary before any Governmental Person, referee or arbitrator that could reasonably be expected to have a Material Adverse Effect.

     (g) No event has occurred and is continuing, or would result from the effectiveness of this Amendment, which constitutes a Default.

Section 5. Reference to and Effect on the Credit Agreement.

     (a) On and after the effective date of this Amendment, each reference in the Credit Agreement to “this Agreement,” “hereunder,” “hereof,” “herein” or words of like import shall mean and be a reference to the Credit Agreement, and each reference in the other Credit Documents to “the Credit Agreement,” “thereunder,” “thereof,” “therein” or words of like import referring to the Credit Agreement, shall mean and be a reference to the Credit Agreement as amended by this Amendment.

     (b) Except as specifically amended above, the Credit Agreement and the other Credit Documents shall remain in full force and effect and are hereby ratified and confirmed. Without limiting the generality of the foregoing, the Security Documents and all of the Collateral described therein do and shall continue to secure the payment of all obligations stated to be secured thereby under the Credit Documents.

     (c) Except as expressly set forth herein, the execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or remedy of the Administrative Agent or any Bank under any of the Credit Documents or constitute a waiver of any provision of any of the Credit Documents.

Section 6. Execution in Counterparts. This Amendment may be executed in any number of counterparts and by the parties hereto in separate counterparts, each which when so executed and delivered shall be deemed to be an original and all of which when taken together shall constitute but one and the same instrument. Delivery of an executed counterpart of a signature page to this Amendment by telecopier shall be effective as delivery of an originally executed counterpart of this Amendment.

Section 7. Governing Law; Binding Effect. This Amendment shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas, and shall be binding upon the Borrower, the Administrative Agent, each Bank and their respective successors and assigns.
