(i) The Company shall have furnished or caused to be furnished to you at the Time of Delivery certificates of officers of the Company satisfactory to you as to the accuracy of the representations and warranties of the Company herein at and as of such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such time, as to the matters set forth in subsections (a) and (f) of this Section and as to such other matters as you may reasonably request.

9. (a) The Company agrees to indemnify and hold harmless each Underwriter against any and all losses, claims, damages and liabilities, joint or several (including any reasonable investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding

or any claim asserted, provided that legal expenses relate to counsel acceptable to the Company), to which they, or any of them, may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities arise solely out of or are based solely upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as any such untrue statement or omission or alleged untrue statement or omission was made in (i) the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with information furnished in writing to the Company by the Representatives on behalf of any Underwriter of Securities expressly for use therein or (ii) that part of the Registration Statement that constitutes the Statement of Eligibility and Qualifications on Form T-1 of the Trustee under the Trust Indenture Act, except statements or omissions in such Form T-1 made in reliance upon information furnished in writing to the Trustee by or on behalf of the Company for use therein.

(b) Each Underwriter agrees to indemnify and hold harmless the Company to the same extent as the foregoing indemnity from the Company to each Underwriter, but only insofar as such losses, claims, damages or liabilities arise solely out of or are based solely upon any untrue statement or omission or alleged untrue statement or omission that was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with information furnished in writing to the Company by the Representatives on behalf of any Underwriter of Securities expressly for use therein; provided, however, that the obligation of each such Underwriter to indemnify the Company hereunder shall be limited to the total price at which the Securities purchased by such Underwriter hereunder were offered to the public.

(c) Any party that proposes to assert the right to be indemnified under this Section 9 will, promptly after receipt of notice of commencement of any action, suit or proceeding against any such party in respect of which a claim is to be made against an indemnifying party under this Section 9, notify each such indemnifying party of the commencement of such action, suit or proceeding, enclosing a copy of all papers served, but the omission so to notify such indemnifying party of any such action, suit or proceeding shall not relieve it from any liability that it may have to any indemnified party otherwise than under Section 9(a) or 9(b), as applicable (it being understood that the omission so to notify such indemnifying party shall relieve it from any liability it may have to any indemnified party under Section 9(a) or 9(b); provided, however, that timely

notice hereunder to the Representatives made pursuant to Section 13 hereof shall be deemed timely notice to any Underwriter that is an indemnifying party). In case any such action, suit or proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, such indemnifying party or parties shall be entitled to participate in, and, to the extent that it or they shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party or parties to such indemnified party of its or their election so to assume the defense thereof, the indemnifying party or parties shall not be liable to such indemnified party for any legal or other expenses, other than reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized in writing by the indemnifying party or parties, (ii) the indemnified party shall have reasonably concluded that there may be a conflict of interest between the indemnifying party or parties and the indemnified party in the conduct of the defense of such action (in which case the indemnifying party or parties shall not have the right to direct the defense of such action on behalf of the indemnified party), or (iii) the indemnifying party or parties shall not in fact have employed counsel to assume the defense of such action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party or parties. In the event that the indemnified party retains separate counsel pursuant to clause (i), (ii), or (iii) of the previous sentence, such counsel shall be reasonably acceptable to the indemnifying party. Any indemnifying party shall not be liable for any settlement of any action or claim effected without its written consent.

(d) If the indemnification provided for in this Section 9 is unavailable to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein (other than because such indemnification, by its terms, does not apply), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities to which such loss, claim, damage or liability (or actions in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company 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 (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and such Underwriters

on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriters. 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 Company on the one hand or such Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (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 that does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in 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 such action or claim. 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 Securities underwritten by it and distributed to investors were offered to investors exceeds the amount of any damages that such Underwriter 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to such Securities and not joint.

(e) The obligations of the Company under this Section 9 shall be in addition to any liability that the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

10. (a) If any Underwriter shall default in its obligation to purchase any Securities that it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that

it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to prepare and file promptly any amendments or supplements to the Registration Statement or the Prospectus that in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-tenth of the aggregate principal amount of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities that remains unpurchased exceeds one-tenth of the aggregate principal amount of the Securities, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(d) For purposes of this Section 10, the 2016 Notes, the 2021 Notes and the 2041 Notes shall be treated as three separate series of Securities, and Section 10 shall apply to each series as if this Agreement applied solely to such series.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling

person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the representatives in care of Citigroup Global Markets Inc., 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000 (Fax: (000) 000-0000), Attention: General Counsel and X.X. Xxxxxx Securities LLC, 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, 00000 (Fax: (000) 000-0000), Attention: High Grade Syndicate Desk; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Vice President and Treasurer (with a copy, which shall not constitute notice, to the Senior Vice President and General Counsel); provided, however, that any notice to a Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

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

18. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

19. The Company is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Underwriters imposing any limitation of any kind.

If the foregoing is in accordance with your understanding, please sign and return to us counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and the Company. It is understood that your acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement among Underwriters, the form of which shall be submitted to the Company for examination upon request, but without warranty on your part as to the authority of the signers thereof.

ANNEX I

Form of opinion of Xxxxx Lovells US LLP, counsel for the Company

The Company is validly existing as a corporation and in good standing, under the Maryland General Corporation Law. The Company has the corporate power and corporate authority under the Charter and the Maryland General Corporation Law to execute, deliver and perform its obligation under the Underwriting Agreement, the Indenture and the Securities and to own, lease and operate its current properties and to conduct its business as described in the Pricing Disclosure Package and the Prospectus.

2.	The Underwriting Agreement has been duly authorized, executed and delivered on behalf of the Company.

The Securities have been duly authorized by the Company, and, when the Securities have been duly executed and authenticated in accordance with the Indenture and delivered against payment of the consideration therefor in accordance with the Underwriting Agreement, each registered holder of a Note will be entitled to the benefits of the Indenture and the Securities will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

4.	The Indenture has been duly authorized, executed and delivered by the Company and constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

The information contained in the Pricing Prospectus and the Prospectus under the captions “Description of Debt Securities,” “Description of the Notes,” and “Certain United States Federal Tax Consequences,” to the extent that such information constitutes matters of law or legal conclusions or purports to describe certain provisions of the Underwriting Agreement, the Indenture and the Securities, has been reviewed by us and is correct in all material respects.

The execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Securities, and the performance of the Underwriting Agreement, the Indenture and the Securities by the Company on the date of this opinion, do not (i) violate the Charter or Bylaws of the Company or (ii) violate any provision of applicable internal Maryland law or applicable federal statutes and regulations.

7.	The Registration Statement became effective under the Securities Act upon its filing with the Commission and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities

A-I-1

Act and no proceedings for such purpose have been instituted or are threatened by the Commission against the Company.

The Registration Statement and the Prospectus (except for the Statement of Eligibility on Form T-1 and the financial statements and supporting schedules and other financial data included or incorporated therein, or omitted therefrom, as to which we express no opinion), as of their respective effectiveness or issue dates, complied as to form in all material respects with the requirements of the Securities Act.

No approval, authorization, order, registration, qualification or consent of, or filing with, any federal governmental agency or the State Department of Assessments and Taxation of the State of Maryland is required to be obtained or made by the Company under applicable federal statutes and regulations, the Maryland General Corporation Law or applicable internal Maryland law in connection with the execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Securities, and the performance of the Underwriting Agreement, the Indenture and the Securities by the Company on the date of this opinion.

10.	The Indenture has been duly qualified under the Trust Indenture Act.

No facts have come to our attention that cause us to believe that:

(i) the Registration Statement, as of the date of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(ii) the Prospectus, as of its date or as of the Time of Delivery, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(iii) the Pricing Disclosure Package, as of 4:00 p.m. (New York City time) on September 6, 2011 (which we have assumed with your permission is a time prior to the time of the first sale of the Securities by any Underwriter), contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that in making the foregoing statements, we do not express any belief with respect to the financial statements and supporting schedules and other financial or accounting information and data derived from such financial statements and schedules or derived from the books and records of the Company or

A-I-2

with respect to reports on the effectiveness of internal control over financial reporting contained or incorporated by reference in or omitted from the Registration Statement, the Pricing Disclosure Package or the Prospectus.

A-I-3

ANNEX II

Form of opinion of In-house counsel to the Company

The Company is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction in which the conduct of its business requires such qualification, except where the failure to qualify and be in good standing would not materially and adversely affect the financial condition of the Company and its subsidiaries taken as a whole.

To my knowledge, other than as set forth or incorporated by reference in the Pricing Disclosure Package, there are not any legal or governmental proceedings pending or threatened to which the Company is subject, or of which any property of the Company is subject, that reasonably are expected to have a material adverse effect on the financial position, stockholders equity or results of operations of the Company and its subsidiaries taken as a whole.

Neither the issue and sale of the Securities, the consummation of any other of the transactions contemplated by the Underwriting Agreement and the Indenture, nor the fulfillment of the terms of the Underwriting Agreement and the Indenture, will conflict with, result in a breach of, or constitute a default under the terms of any indenture or other agreement or instrument to which the Company or any of its subsidiaries is a party or is bound, except where the effect of such conflict, breach or default would not be material to the Company and its subsidiaries taken as a whole and would not adversely affect the consummation of the transactions contemplated thereby.

The documents filed with the Commission pursuant to Section 13(a), 13(c) or 15(d) of the Exchange Act and incorporated by reference into the Pricing Prospectus and the Prospectus, and all documents filed under the Exchange Act and so deemed to be included in the Pricing Prospectus and the Prospectus or any amendment or supplement thereto, (the “Exchange Act Reports”) (other than the financial statements and notes thereto, the financial statements schedules and the other financial data included or incorporated by reference therein, as to which I express no opinion), subject to any amendments or supplements thereto included in the Exchange Act Reports filed before the date of the Underwriting Agreement, when they were filed with the Commission, complied as to form in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder.

The execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Securities, and the performance of the Underwriting Agreement, the Indenture and the Securities by the Company on the date of this opinion, do not, to my knowledge, violate any order or regulation applicable to the
