For the purposes of the above, the expression an “offer of Securities to the public” in relation to any Securities in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase or subscribe for the Securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in that Member State, and the expression “2010 PD Amending Directive” means Directive 3010/73/EU.

(vi) such Initial Purchaser has represented and agreed that it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000) received by it in connection with the issue or sale of the Securities in circumstances in which Section 21(1) of such Act does not apply to us and it has complied and will comply with all applicable provisions of such Act with respect to anything done by it in relation to any Securities in, from or otherwise involving the United Kingdom;

(vii) such Initial Purchaser understands that the Securities have not been and will not be registered under the Securities and Exchange Law of Japan, and represents that it has not offered or sold, and agrees not to offer or sell, directly or indirectly, any Securities in Japan or for the account of any resident thereof except pursuant to any exemption from the registration requirements of the Securities and Exchange Law of Japan and otherwise in compliance with applicable provisions of Japanese law; and

(viii) such Initial Purchaser agrees that, at or prior to confirmation of sales of the Securities, it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the restricted period a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and

may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them by Regulation S.”

Terms used in this Section 7(b) have the meanings given to them by Regulation S.

8. Indemnity and Contribution. (a) Each of the Issuers and the Guarantor, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its directors and officers and each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of each Initial Purchaser within the meaning of Rule 405 under the Securities Act that has participated in the distribution of the Notes from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Time of Sale Memorandum or any amendment or supplement thereto, any Additional Written Offering Communication prepared by or on behalf of, used by, or referred to by the Issuers, or the Final Memorandum or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Issuers by such Initial Purchaser through the Representative expressly for use in the Preliminary Memorandum, the Pricing Supplement, any Additional Written Offering Communication or the Final Memorandum (or any amendment or supplement thereto).

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless each Issuer, each Guarantor, each of their respective directors, officers and each person, if any, who controls either Issuer or any Guarantor within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (including in the directors and officers of the General Partner) to the same extent as the foregoing indemnity from the Issuers and Guarantors to such Initial Purchaser, but only with reference to information relating to such Initial Purchaser furnished to the Issuers by such Initial Purchaser through the Representative expressly for use in the Preliminary Memorandum, the Pricing Supplement, any Additional Written Offering Communication or the Final Memorandum (or any amendment or supplement thereto). Each of the Issuers and the Guarantor hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Issuers expressly for use in the Preliminary Memorandum, the Time of Sale Memorandum, any Additional Written Communication or the Final Memorandum (or any

amendment or supplement thereto) are the statements set forth in (i) the last paragraph of the cover page regarding delivery of the Notes, (ii), the list of Initial Purchasers and their respective participation in the sale of the Notes and (iii) the second and third sentences of the ninth paragraph and tenth paragraphs under the caption “Plan of Distribution” in the Preliminary Memorandum and the Final Memorandum.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing; provided, however, that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 8 except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under this Section 8. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party, (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnified party, or (iv) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would, in the reasonable judgment of the indemnified party, be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Morgan Stanley & Co. LLC, in the case of parties indemnified pursuant to Section 8, and by the Issuers, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if

at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantor on the one hand and the Initial Purchasers on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(d)(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 8(d)(i) above but also the relative fault of the Issuers and the Guarantor on the one hand and of the Initial Purchasers on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Guarantors on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Issuers and the total discounts and commissions received by the Initial Purchasers bear to the aggregate offering price of the Securities. The relative fault of the Issuers and the Guarantor on the one hand and of the Initial Purchasers on the other hand 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 Issuers or the Guarantors, or by the Initial Purchasers, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have

purchased hereunder as set forth opposite their names in Schedule I hereto, and not joint.

(e) The Issuers and the Guarantors and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to Section 8(d) were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Issuers contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Initial Purchaser, any person controlling any Initial Purchaser or any affiliate of any Initial Purchaser or by or on behalf of the Issuers, their respective officers or directors or any person controlling either Issuer and (iii) acceptance of and payment for any of the Securities.

9. Termination. The Representative may terminate this Agreement by notice given by you to the Issuers, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, the New York Stock Exchange or the NASDAQ Stock Market, (ii) trading of any securities of the Partnership shall have been suspended on any exchange or in any over the counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, the judgment of the Representative, impracticable or

inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum or the Final Memorandum.

10. Effectiveness; Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one tenth of the aggregate principal amount of Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Securities set forth opposite the names of all such non defaulting Initial Purchasers, or in such other proportions as may be specified by the Representative with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one ninth of such principal amount of Securities without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one tenth of the aggregate principal amount of Securities to be purchased on the Closing Date, and arrangements satisfactory to the you and the Issuers for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or of the Issuers or any Guarantor except that the provisions of Sections 6(g), 8 and 11 hereof shall at all times be effective and shall survive such termination. In any such case either the Representative or the Issuers shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum, the Final Memorandum or in any other documents or arrangements may be effected. As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 10. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

11. Reimbursement of the Expenses of the Initial Purchasers. If the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 5 hereof is not satisfied, if this Agreement shall be terminated by the Representative pursuant to Section 9(ii) or because of any failure or refusal on the part of the Issuers to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Issuers shall be unable to perform their obligations under this Agreement, the Issuers will reimburse the Initial Purchasers, severally, upon demand for all out-of-pocket expenses (including the fees and

disbursements of their counsel) reasonably incurred by each such Initial Purchaser in connection with this Agreement or the offering contemplated hereunder. The Issuers and the Guarantor shall not be obligated to reimburse such costs and expenses of a defaulting Initial Purchaser if this Agreement is terminated pursuant to Section 10 by reason of the default of an Initial Purchaser.

12. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Issuers and the Initial Purchasers with respect to the preparation of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b) This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuers, the Guarantors and the Initial Purchasers, or any of them, with respect to the subject matter hereof.

(c) The Issuers acknowledge that in connection with the offering of the Securities: (i) the Initial Purchasers have acted at arms-length, are not agents of, and owe no fiduciary duties to, the Issuers, the Guarantors or any other person, (ii) the Initial Purchasers owe the Issuers only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement) if any, (iii) the Initial Purchasers may have interests that differ from those of the Issuers and the Guarantor, and (iv) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Issuers and the Guarantor have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate. Each of the Issuers and the Guarantor waives to the full extent permitted by applicable law any claims it may have against the Initial Purchasers arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

13. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the indemnified parties referred to in Section 8 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of

any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

16. Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by the Representative on behalf of the Initial Purchasers, and any such action taken by the Representative shall be binding upon the Initial Purchasers.

17. 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 Issuers, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients.

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

(a) Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum.

19. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.
