8. Indemnification and Contribution . (a)  Indemnification of Underwriters . The Partnership shall indemnify and hold harmless each Underwriter, its officers, employees, agents, partners, members, directors and affiliates of any Underwriter who have, or who are alleged to have, participated in the distribution of the Offered Securities as underwriters, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “ Indemnified Party ”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus (which term includes any base prospectus and any preliminary prospectus supplement) as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary in order to make the statements therein, in the case of any Statutory Prospectus or the Final Prospectus, in the light of the circumstances under which they were made, not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating, preparing or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however , that the Partnership shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below.

(b) Indemnification of Partnership . Each Underwriter shall severally and not jointly indemnify and hold harmless the Partnership, its directors and officers and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “ Underwriter Indemnified Party ”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement

of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus (which term includes any base prospectus and any preliminary prospectus supplement) as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary in order to make the statements therein, in the case of any Statutory Prospectus or the Final Prospectus, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating, preparing or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus: (i) the statements regarding the concession and reallowance figures appearing in the third paragraph under the caption “Underwriters,” (ii) information relating to stabilization appearing in the sixth paragraph under the caption “Underwriting,” (iii) information relating to fees and expenses and activities and commercial transactions of the underwriters and their affiliates in the eighth paragraph under the caption “Underwriting” and (iv) information relating to hedging transactions by the underwriters or their affiliates in the ninth paragraph under the caption “Underwriting”; provided, however , that the Underwriters shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Partnership’s failure to perform its obligations under Sections 5(a), (b) or (c) of this Agreement.

(c) Actions against Parties; Notification . Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and

indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) Contribution . If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Partnership on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total discounts and commissions received by the Underwriters from the Partnership under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. The Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(d).

9. Default of Underwriters. If any Underwriter defaults in its obligation to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Underwriter agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the non-defaulting Underwriter may make arrangements satisfactory to the Partnership for the purchase of such Offered Securities by other persons, including itself, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriter shall be obligated to purchase the Offered Securities that such defaulting Underwriter agreed but failed to purchase. If any Underwriter so defaults and the aggregate

principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the non-defaulting Underwriter and the Partnership for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Partnership, except as provided in Section 10. As used in this Agreement, the term “Underwriter” includes any person substituted for a Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Compliance with USA Patriot Act . In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Partnership or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Partnership or any of its representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Partnership shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Partnership and the Underwriters pursuant to Section 8 shall remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clauses (iii), (iv), (vi), (vii) or (viii) of Section 7(c), the Partnership will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

12. Notices. All communications hereunder will be in writing and, if sent to the Underwriters will be mailed, delivered or telegraphed and confirmed to the Underwriters, c/o Deutsche Bank Securities Inc., 60 Wall Street, New York, New York 10005, Attention: Leveraged Debt Capital Markets, with a copy at the same address to: Attention of the General Counsel, 36 ^th Floor and c/o Morgan Stanley & Co.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the other persons referred to in Section 8, and no other person will have any right or obligation hereunder.

14. [Reserved] .

15. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

16. Absence of Fiduciary Relationship. The Partnership acknowledges and agrees that:

(a) No Other Relationship . The Underwriters have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Partnership and the Underwriters has been created in respect of any of the transactions contemplated by this Agreement or the Preliminary or the Final Prospectus, irrespective of whether the Underwriters have advised or are advising the Partnership on other matters;

(b) Arm’s-Length Negotiations .

(c) Absence of Obligation to Disclose . The Partnership has been advised that the Underwriters and their affiliates are engaged in a broad range of transactions that may involve interests that differ from those of the Partnership and that the Underwriters have no obligation to disclose such interests and transactions to the Partnership by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver . The Partnership waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Partnership in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Partnership, including equityholders, employees or creditors of the Partnership.

17. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
