The Securities will be issued pursuant to an indenture (the “Base Indenture”), to be dated as of the Closing Date (as hereinafter defined), between the Company and U.S. Bank National Association, as trustee (the “Trustee”), as amended and supplemented by the First Supplemental Indenture (herein so called), the Second Supplemental Indenture (herein so called) and the Third Supplemental Indenture (herein so called), each to be dated as of the Closing Date, establishing the forms and terms of the 2017 Notes, the 2022 Notes and the 2042 Notes, respectively. The term “Indenture” as used herein refers to the Base Indenture as so amended and supplemented.

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the 1934 Act on or before the effective date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any document filed under the 1934 Act after the effective date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Prospectus, as the case may be, and deemed to be incorporated therein by reference. Certain terms used herein are defined in Section 16 hereof.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof, as of the Applicable Time, and as of the Closing Date referred to in Section 2(b) hereof, and agrees with each Underwriter, as follows:

(1) Status as a Well-Known Seasoned Issuer. (A) At the respective times the Registration Statement or any amendments thereto were filed with the Commission, (B) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at any time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption of Rule 163 and (D) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405 and is eligible to use an “automatic shelf registration statement,” as defined in Rule 405 and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on such an “automatic shelf registration statement.” The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of an automatic shelf registration statement and was not and is not an “ineligible issuer” (as defined in Rule 405). Any written communication that was an offer relating to the Securities made by the Company or any person acting on its behalf (within the meaning, for this sentence only, of

Rule 163(c)) prior to the filing of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

(2) Compliance with Registration Requirements. The Company meets the requirements for use of Form S-3 under the 1933 Act and has prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405, on Form S-3, including a related Base Prospectus, for registration under the 1933 Act of the offering and sale of the Securities. The Registration Statement and any post-effective amendments thereto became effective upon filing under the 1933 Act, and no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act, and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

(3) Registration Statement. The Registration Statement did not and will not, as of each effective date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Registration Statement in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter expressly for use therein, which information is specified in Section 10 hereof.

(4) Prospectus. The Prospectus will not, as of its date and on the Closing Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Preliminary Prospectus and the Prospectus and any amendments or supplements to any of the foregoing filed as part of the Registration Statement or any amendment thereto, filed pursuant to Rule 424 under the 1933 Act, or delivered to the Underwriters for use in connection with the offering of the Securities, complied when so filed or when so delivered, as the case may be, in all material respects with the 1933 Act and the 1933 Act Regulations; provided that no representation or warranty is made as to information contained in or omitted from the Prospectus in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter expressly for use therein, which information is specified in Section 10 hereof.

(5) General Disclosure Package. The General Disclosure Package did not, as of the Applicable Time, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information contained in or omitted from the General Disclosure Package in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriters expressly for use therein, which information is specified in Section 10 hereof.

(6) Delivery of Documents. The copies of the Registration Statement and any amendments thereto and the copies of each Preliminary Prospectus, each Issuer Free Writing Prospectus that is required to be filed with the Commission pursuant to Rule 433 and the Prospectus and any amendments or supplements to any of the foregoing, that have been or subsequently are delivered to the Underwriters in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise) were and will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T of the Commission. For purposes of this Agreement, references to the “delivery” or “furnishing” of any of the foregoing documents to the Underwriters, and any similar terms, include, without limitation, electronic delivery.

(7) Issuer Free Writing Prospectus. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offering and sale of the Securities did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any Preliminary Prospectus or the Prospectus that has not been superseded or modified.

(8) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, any Preliminary Prospectus and the Prospectus, at the respective times they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations, as applicable, and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

The Company and its subsidiaries have filed all foreign, federal, state and local tax returns that are required to be filed or have obtained extensions thereof, except where the failure so to file would not, individually or in the aggregate, result in a Material Adverse Effect, and have paid all taxes (including, without limitation, any estimated taxes) required to be paid and any other assessment, fine or penalty, to the extent that any of the foregoing is due and payable, except for any such tax, assessment, fine or penalty that is currently being contested in good faith by appropriate actions and except for such taxes, assessments, fines or penalties the nonpayment of which would not, individually or in the aggregate, result in a Material Adverse Effect.

(33) Insurance. The Company and its subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which they are engaged. All policies of

insurance and any fidelity or surety bonds insuring the Company or any of its subsidiaries or their respective businesses, assets, employees, officers and directors are in full force and effect; the Company and its subsidiaries are in compliance with the terms of such policies and instruments in all material respects; there are no claims by the Company or any of its subsidiaries under any such policy or instrument as to which any insurance company is denying liability and which such denial might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect; and neither the Company nor any such subsidiary has been refused any insurance coverage sought or applied and which such refusal might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. Neither the Company nor any such subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers at a cost that would not, individually or in the aggregate, result in a Material Adverse Effect.

(34) Accounting and Disclosure Controls. The Company and its subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (1) no material weakness (as defined in Rule 1-02 of Regulation S-X of the Commission) in the Company’s internal control over financial reporting (whether or not remediated), and (2) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company and its subsidiaries have established, maintained and periodically evaluate the effectiveness of “disclosure controls and procedures” (as defined in Rules 13a-15 and 15d-15 under the 1934 Act); such disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports that it will be required to file or submit under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and is accumulated and communicated to the Company’s management, including its principal executive officer or officers and principal financial officer or officers, as appropriate, to allow timely decisions regarding disclosure.

(35) Compliance with the Xxxxxxxx-Xxxxx Act. There is and has been no failure on the part of the Company or any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the Xxxxxxxx-Xxxxx Act with which any of them is required to comply, including Section 402 related to loans.

The Registration Statement is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the 1933 Act, and the Company is not the subject of a pending proceeding under Section 8A of the 1933 Act.

(37) Absence of Manipulation. The Company has not taken and will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security to facilitate the sale or resale of the Securities.

(38) Statistical and Market-Related Data. Any statistical, demographic, market-related and similar data included in the Registration Statement, the General Disclosure Package or the Prospectus are based on or derived from sources that the Company believes to be reliable and accurate and accurately reflect the materials upon which such data is based or from which it was derived.

(39) Foreign Corrupt Practices Act. Except as disclosed in the Registration Statement, the Prospectus and the General Disclosure Package, (a) neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee, affiliate or other person acting on behalf of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that has resulted or would result in a violation by any such person of the FCPA, including, without limitation, any offer, payment, promise to pay or authorization of the payment of any money or other property, gift, promise to give or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA, (b) the Company and its subsidiaries, and, to the knowledge of the Company, its other affiliates have conducted their businesses in compliance with the FCPA, and (c) the Company and its subsidiaries, and, to the knowledge of the Company, its other affiliates have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to ensure, continued compliance with the FCPA, except, in the case of clauses (a) and (b), where any such violation or noncompliance would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

The operations of the Company and its subsidiaries are and have been conducted at all times in all material respects in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money

laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened.

(b) Certificates. Any certificate signed by any officer of the Company or any of its subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) and

SECTION 2. Sale and Delivery to Underwriters; Closing.

(a) The Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company (i) the aggregate principal amount of 2017 Notes set forth opposite such Underwriter’s name in Exhibit A hereto at a price equal to 99.303% of the principal amount thereof, (ii) the aggregate principal amount of 2022 Notes set forth opposite such Underwriter’s name in Exhibit A hereto at a price equal to 98.990% of the principal amount thereof, and (iii) the aggregate principal amount of 2042 Notes set forth opposite such Underwriter’s name in Exhibit A hereto at a price equal to 98.740% of the principal amount thereof, in each case, plus any additional principal amount of Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, and in each case plus accrued interest, if any, from November 20, 2012 to the Closing Date.

(b) Payment. Payment of the purchase price for, and delivery of, the Securities shall be made at the offices of Bracewell & Xxxxxxxx LLP, 000 Xxxxxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M.

Wells Fargo, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Securities to be purchased by any Underwriter whose funds have not been received by the Closing Date, but such payment shall not relieve such Underwriter from its obligations hereunder.

The Company has given the Representatives notice of any filings made pursuant to the 1934 Act or the 1934 Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time through the Closing Time (or, if later, through the end of the period during which the Prospectus is required (or, but for the provisions of Rule 172, would be required) to be delivered by applicable law (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise)) and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall object.

In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters and the other indemnified parties referred to in Section 6(a) above; and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced

or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. 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 this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) 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 hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or by the Underwriters on the other hand 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 Section 7 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 above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, 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 the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each affiliate, officer, director, employee, partner and member of each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Company or any of its subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) and delivered to the Representatives or counsel to the Underwriters, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person controlling any Underwriter, or by or on behalf of the Company, any officer, director or employee of the Company or any person controlling the Company, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time on or prior to Closing Date (i) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or

economic conditions (including, without limitation, as a result of terrorist activities), in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (ii) (A) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or (B) if trading generally on the NYSE has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by such exchange or by order of the Commission, FINRA or any other governmental authority, or (C) if a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to the Clearstream or Euroclear systems in Europe, (iii) if a banking moratorium has been declared by either Federal or New York authorities, or (iv) if any condition specified in Section 5 shall not have been fulfilled when and as required to be fulfilled.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and except that Sections 4, 6, 7, 12, 13 and 14 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Underwriters’ Information. The following constitutes the only information furnished to the Company through the Representatives by or on behalf of the Underwriters expressly for use in the Pre-Pricing Prospectus and the Prospectus as such information is referred to in Sections 1 and 6 herein: under the caption “Underwriting” in the Pre-Pricing Prospectus and in the Prospectus, (i) the information regarding the selling concessions and reallowances and (ii) the information regarding stabilization, syndicate covering transactions and penalty bids (but only insofar as such information concerns the Underwriters) and (iii) the information regarding market making by the Underwriters.

SECTION 11. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Date to purchase the aggregate principal amount of Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 11 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, the Representatives shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

FORM OF OPINION OF COMPANY COUNSEL

(1) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware.

(2) The Company has corporate power and authority to own or lease, as the case may be, and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and to enter into and perform its obligations under the Underwriting Agreement, the Indenture and the Securities.

(3) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(4) Each of the Base Indenture, the First Supplemental Indenture, the Second Supplemental Indenture and the Third Supplemental Indenture has been duly authorized, executed and delivered by the Company, and assuming due authorization, execution and delivery thereof by the Trustee, the Indenture constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general principles of equity.

(5) The Securities have been duly authorized and executed by the Company and, when authenticated in the manner provided for in the Indenture and delivered against payment of the purchase price therefor as provided in the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general principles of equity.

(6) The Registration Statement has become effective under the 1933 Act; the Pre-Pricing Prospectus and the Prospectus and any amendments or supplements thereto have been filed with the Commission pursuant to Rule 424(b) in the manner and within the time period required by Rule 424(b) (without reference to Rule 424(b)(8)); any required filing of each Issuer Free Writing Prospectus pursuant to Rule 433 has been made in the manner and within the time period required by Rule 433(d); and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted by or are pending before the Commission.

(7) The Registration Statement, at the time it first became effective, and the Registration Statement (including the Rule 430B Information), at each deemed new effective date with respect to the Underwriters pursuant to Rule 430B(f)(2), and the Prospectus and any amendments or supplements thereto, as of their respective dates, complied as to form in all material respects with the requirements of the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations; it being understood, however, that such counsel need express no

D - 1

view with respect to the Form T-1, Regulation S-T or the financial statements, schedules or other financial data, included in, incorporated by reference in, or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, such counsel may assume that the statements made in the Registration Statement, the General Disclosure Package and the Prospectus are correct and complete.

(8) The statements included in the General Disclosure Package and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities,” insofar as they purport to constitute summaries of the terms of the Securities, are accurate summaries of the terms thereof in all material respects. The statements included in the General Disclosure Package and the Prospectus under the caption “Certain United States Federal Income Tax Considerations,” to the extent that such statements purport to describe or summarize the legal matters therein, accurately summarize in all material respects such legal matters.

(9) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is required for the execution, delivery and performance by the Company of each of the Transaction Documents, the issuance and sale of the Securities and compliance by the Company with the terms thereof and the consummation of the transactions contemplated by the Transaction Documents, except for such filings, consents, approvals, authorizations, orders and registrations or qualifications as may be required under applicable state securities laws in connection with the purchase and distribution of the Securities by the Underwriters and any consent, approval, authorization, order, registration or qualification that has been obtained or made, or which if not obtained or made, would not, individually or in the aggregate, have a Material Adverse Effect. With respect to this paragraph (9), such counsel need not express any opinion with respect to consents, approvals, authorizations, orders and registrations or qualifications as may be required under applicable federal or state antifraud laws, rules or regulations.

(10) The execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated in the Transaction Documents, the Registration Statement, the General Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the General Disclosure Package and the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations under the Transaction Documents do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default, Termination Event or Repayment Event under, or result in the creation or imposition of any Lien upon any property or assets of the Company or any of its subsidiaries pursuant to any Company Document, except for such conflicts, breaches, defaults or Liens that would not, individually or in the aggregate, result in a Material Adverse Effect, nor will such action result in any violation of the provisions of the Organizational Documents of the Company or any Significant Subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any government, government instrumentality or court having jurisdiction over the Company or any of its subsidiaries or any of their respective assets, properties or operations, excluding any anti-fraud or similar law, rule or regulation.

(11) The Company is not, and, upon the issuance and sale of the Securities as contemplated in the Underwriting Agreement and the receipt and application of the net proceeds

D - 2

therefrom as described in the General Disclosure Package and the Prospectus under the caption “Use of Proceeds,” will not be an “investment company” or an entity “controlled” by an “investment company” as such terms are defined in the 1940 Act.

In addition, such counsel shall state that, in acting as counsel to the Company in connection with the transactions contemplated by the Underwriting Agreement they have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants and counsel for the Company and representatives of the Underwriters, at which conferences the contents of the Registration Statement, the General Disclosure Package and the Prospectus, and any supplements or amendments to any of the foregoing, and related matters were discussed. Although such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements in the Registration Statement, the General Disclosure Package, the Prospectus or any supplements and amendments to any of the foregoing, and has made no independent check or verification thereof (except as set forth in paragraph 8 above), nothing has come to such counsel’s attention that would lead such counsel to believe that

(1) the Registration Statement or any post-effective amendments thereto, at the respective times they first became effective, or the Registration Statement or any post-effective amendments thereto (in each case including the Rule 430B Information), at each deemed new effective date with respect to the Underwriters pursuant to Rule 430B(f)(2), 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;

(2) the General Disclosure Package, as of the Applicable Time, included 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; or

(3) the Prospectus and any supplements thereto, as of the date of the Prospectus, as of the date of any such supplement or as of the date of this letter, included or includes 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,

except in each case that such counsel expresses no view with respect to the Form T-1, Regulation S-T or the financial statements, schedules and other financial or statistical data included in, incorporated by reference in, or omitted from the Registration Statement, the General Disclosure Package, or the Prospectus or any amendment or supplement to any of the foregoing.

Except as otherwise provided herein, in the event that such opinion shall define the term “Registration Statement,” “Pre-Pricing Prospectus,” or “Prospectus” (rather than indicating that such terms, as used in such opinion, have the respective meanings given thereto in the Underwriting Agreement), such opinion shall define the terms “Registration Statement,” “Pre-Pricing Prospectus” and “Prospectus” to include the documents incorporated or deemed to be incorporated by reference therein.

D - 3

In rendering such opinion, Company Counsel shall state that such opinion covers matters arising under the laws of the States of Texas and New York, the Delaware General Corporation Law and the federal laws of the United States of America. In rendering such opinion, Company Counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

D - 4

EXHIBIT E

FORM OF OPINION OF GENERAL COUNSEL

To such counsel’s knowledge, except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending or threatened, against or affecting the Company or any of its subsidiaries which is required to be disclosed in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, or which might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or to materially and adversely affect the consummation of the transactions contemplated in the Transaction Documents or the performance by the Company of its obligations thereunder.

Such opinion shall define the term “knowledge” to mean the actual knowledge of such counsel after inquiry of personnel of the Company who have responsibility for the subject matter of such opinion.

In the event that such opinion shall define the term “Registration Statement,” “General Disclosure Package” or “Prospectus” (rather than indicating that such terms, as used in such opinion, have the respective meanings given thereto in the Underwriting Agreement), such opinion shall define the terms “Registration Statement,” “General Disclosure Package” and “Prospectus” to include the documents incorporated or deemed to be incorporated by reference therein.
