        (a)   The execution, delivery and performance by the Borrower of this Amendment, the New Notes and the Credit Documents, as amended hereby and thereby, to which the Borrower is a party 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) contravene any Governmental Rule or contractual restriction binding on or affecting the Borrower or (iii) result in or require the creation or imposition of any Lien (other than any created by the Credit Documents) upon or with respect to any of the properties of the Borrower.

        (b)   No Governmental Action is required for the due execution, delivery or performance by the Borrower or this Amendment, the New Notes or any of the Credit Documents, as amended hereby and thereby, to which the Borrower is a party.

        (c)   This Amendment, the New Notes and each of the Credit Documents, as amended hereby and thereby, to which the Borrower is a party constitute legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective 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.

        (d)   Each of the Security Documents constitutes an Acceptable Security Interest on the Collateral purported to be encumbered thereby, enforceable against all third parties in all jurisdictions, and secures the payment of all obligations stated to be secured thereby under the Credit Documents, as amended hereby and by the New Notes, and the execution, delivery and performance of this Amendment and the New Notes do not adversely affect any Lien of the Collateral 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). Since December 31, 2002 there has been no material and adverse change in the business, condition (financial or otherwise), operations, performance, properties or prospects of the Borrower or any Subsidiary.

        (g)   There has been no amendment to the Borrower Partnership Agreement. The representations and warranties of the Borrower contained in the Credit Documents are correct on and as of the date hereof as though made on and as of such date except to the extent any such representation or warranty is stated to relate solely to an earlier date, in which case such representation or warranty shall have been true and correct on such earlier date. No event has occurred and is continuing, or would result from the effectiveness of this Amendment, that constitutes a Default.

        (b)   Except as specifically amended above and except for the issuance of the New Notes, 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 Collateral 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, as amended hereby and by the New Notes.
