In addition, following receipt of a written request from a Purchaser that continues to own Purchased Units, the Partnership shall provide such Purchaser with a good faith estimate (and reasonable supporting calculations) of whether there is sufficient Unrealized Gain attributable to the Partnership property on the date of such request such that, if any of such Purchaser’s Series A Preferred Units were converted to Common Units and such Unrealized Gain was allocated to such Purchaser pursuant to Section 5.5(d)(iii) of the Partnership Agreement (taking proper account of allocations of higher priority), Purchaser’s Capital Account in respect of its Common Units would be equal to the Per Unit Capital Amount for an Initial Common Unit without any need for corrective allocations under Section 6.2(i) of the Partnership Agreement.

For the avoidance of doubt, no Purchaser shall be required to pay to the Partnership an amount of cash equal to any cash distributions paid by the Partnership with respect to such Common Units for quarters beginning after the termination of the Conversion Period. Each Purchaser agrees that no transfer of the Securities before the termination of the Conversion Period shall be recognized by the Partnership unless the transferee agrees to be bound by the terms of this Section 5.14 and executes and delivers to the Partnership an acknowledgment and agreement to such effect.

No Purchaser Related Party shall be entitled to recover special, indirect, exemplary, incidental, lost profits, speculative or punitive damages under this Section 6.01 ; provided , however , that such limitation shall not prevent any Purchaser Related Party from recovering under this Section 6.01 for any such damages to the extent that such damages are direct damages in the form of diminution in value or are payable to a third party in connection with any Third-Party Claims.

Section 6.02 Indemnification Procedure .

(a) A claim for indemnification for any matter not involving a Third-Party Claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article VI , except as otherwise provided in Section 6.01 .

34

(b) As soon as reasonably practicable after any Purchaser Related Party (hereinafter, the “ Indemnified Party ”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (each a “ Third-Party Claim ”), the Indemnified Party shall give the indemnitor hereunder (the “ Indemnifying Party ”) written notice of such Third-Party Claim, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such Third-Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly, and in no event later than ten (10) days, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided , however , that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a Third-Party Claim, failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party and to notify the Indemnified Party of such assumption or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party or its Affiliates. The remedies provided for in this Section 6.02 are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

Section 6.03 Tax Matters . All indemnification payments under this Article VI shall be adjustments to the Purchaser’s Purchase Price except as otherwise required by applicable Law.

Schedule A

EXHIBIT A

FORM OF OPINION OF VINSON & ELKINS L.L.P.

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Series A Preferred Unit Purchase Agreement (the “ Purchase Agreement ”). The Partnership shall furnish to the Purchasers at the Closing an opinion of Vinson & Elkins L.L.P., counsel for the Partnership, addressed to the Purchasers and dated the Closing Date in form satisfactory to the Purchasers, stating that:

(i) Each of the Partnership, the General Partner and the subsidiaries of the Partnership listed on Schedule I hereto (the “ Domestic Subsidiaries ”) is validly existing and in good standing under the laws of its jurisdiction of formation. Each of the Partnership, the General Partner and the Domestic Subsidiaries has all requisite corporate, limited liability company or partnership power and authority, as applicable, under the laws of its jurisdiction of formation necessary to own or lease its properties and to conduct its business, in each case as described in the Partnership SEC Documents. The Partnership, the General Partner and the Domestic Subsidiaries are each duly qualified to do business and are each in good standing in each jurisdiction listed on Schedule I.

(ii) Except as have been waived or satisfied, there are no preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any interests in the Partnership pursuant to the Organizational Documents of the Partnership or any agreement, instrument or other document filed as an exhibit to the Partnership SEC Documents. There are no securities or instruments filed as an exhibit to the Partnership SEC Documents containing anti-dilution or similar provisions that will be triggered by the issuance of the Securities.

(iii) The Purchased Units to be issued and sold to the Purchasers by the Partnership pursuant to the Purchase Agreement and the limited partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Purchasers against payment therefor in accordance with the terms of the Purchase Agreement, will be validly issued in accordance with the terms of the Partnership Agreement, fully paid and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

(iv) Assuming the distribution of the PIK Units is properly authorized by the board of directors of the General Partner and that the PIK Units are issued in accordance with the terms of the Partnership Agreement, the PIK Units will be duly authorized, validly issued, fully paid and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act) and, except pursuant to applicable law, the Partnership Agreement or as provided on Schedule II hereto, will be free of any liens, charges or preemptive or similar rights contained in the Partnership Agreement or any agreement, instrument or other documents filed as an exhibit to the Partnership SEC Documents.

(v) The Conversion Units and the Additional Conversion Units have been duly authorized by the General Partner on behalf of the Partnership pursuant to the Partnership Agreement and, when issued upon conversion of the Purchased Units and the PIK Units in accordance with the

Exhibit A

terms of the Partnership Agreement, will be validly issued, fully paid (to the extent required by applicable law and the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

(vi) No consent, approval, authorization, filing with or order of any federal or Delaware court, Governmental Authority or body having jurisdiction over the Partnership is required for the issuance and sale by the Partnership of the Purchased Units, the execution, delivery and performance by the Partnership of the Transaction Documents, or the consummation of the transactions contemplated by the Transaction Documents, except (i) as may be required in connection with the Partnership’s obligations under the Registration Rights Agreement to register the resale of the Conversion Units and the Additional Conversion Units under the Securities Act, (ii) those that have been obtained, (iii) as may be required under state securities or “Blue Sky” laws, as to which we do not express any opinion, or (iv) such that the failure to obtain would not reasonably be expected to have a Material Adverse Effect.

(vii) Assuming the accuracy of the representations and warranties of the Purchasers and the Partnership contained in the Purchase Agreement, the offer, issuance and sale of the Purchased Units and the PIK Units by the Partnership to the Purchasers solely in the manner contemplated by the Purchase Agreement are, and the issuance and delivery of the Conversion Units and the Additional Conversion Units will be, exempt from the registration requirements of the Securities Act; provided , however , that we express no opinion as to any subsequent sale or resale of the Purchased Units, the PIK Units, the Conversion Units or the Additional Conversion Units.

(viii) The Partnership is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

(ix) None of the offering, issuance or sale by the Partnership of the Purchased Units or the execution, delivery and performance of the Transaction Documents by the Partnership or the General Partner, as the case may be, or the consummation of the transactions contemplated thereby will result in a breach or violation of, or constitute a default (or an event which, with the giving of notice or lapse of time or both, constitutes or would constitute a default) under, or give rise to any right of termination, cancellation or acceleration under (A) the Organizational Documents of the Partnership or the General Partner, as the case may be, (B) any agreement filed as an exhibit to the Partnership SEC Documents, except for the Credit Facilities, or (C) the Delaware LP Act or U.S. federal law or any applicable law of the State of New York, which in the case of clauses (B) or (C) would be reasonably expected to have a Material Adverse Effect.

(x) Each of Transaction Documents has been duly authorized and validly executed and delivered by the Partnership or the General Partner, as the case may be, and the Partnership Agreement constitutes a valid and binding obligation of the General Partner, enforceable against the General Partner in accordance with its terms, except insofar as the enforceability thereof may be limited by (A) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to

Exhibit A

fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. The Partnership and the General Partner each has the requisite power and authority to execute, deliver and perform all of its obligations under the Transaction Documents, including, without limitation, the issuance of the Securities in accordance with the terms thereof.
