Exhibit 1.1

▇▇▇▇▇▇▇▇ 66

Debt Securities

fully and unconditionally guaranteed by ▇▇▇▇▇▇▇▇ 66 Company

1. Introductory. ▇▇▇▇▇▇▇▇ 66, a Delaware corporation (the “Parent”), and ▇▇▇▇▇▇▇▇ 66 Company, a Delaware corporation (“▇▇▇▇▇▇▇▇ 66 Company” or the “Guarantor”), propose that the Parent will issue and sell from time to time certain of its unsecured debt securities (the “Debt Securities”) that will be fully and unconditionally guaranteed by ▇▇▇▇▇▇▇▇ 66 Company (the Debt Securities, including the guarantee relating thereto by the Guarantor (the “Guarantee”), being hereinafter called the “Securities”). The Securities will be issued under an indenture, to be dated as of the Closing Date (as defined below) (the “Indenture”), among the Parent, the Guarantor and ▇▇▇▇▇ Fargo Bank, National Association, as trustee (the “Trustee”), in one or more series, which series may vary as to interest rates, maturities, redemption provisions, selling prices and other terms, with all such terms for any particular series of the Securities being determined at the time of sale. Particular series of the Securities will be sold pursuant to a Terms Agreement referred to in Section 3, for resale in accordance with terms of offering determined at the time of sale.

The Securities involved in any such offering are hereinafter referred to as the “Offered Securities”. The firm or firms which agree to purchase the Offered Securities, as set forth in a Terms Agreement referred to in Section 3 hereof, are hereinafter referred to as the “Initial Purchasers” (which term shall include any person substituted for an Initial Purchaser pursuant to Section 8 hereof) of such securities, and the representative or representatives of the Initial Purchasers, if any, specified in a Terms Agreement referred to in Section 3 hereof are hereinafter referred to as the “Representatives”; provided, however, that if the Terms Agreement does not specify any representative of the Initial Purchasers, the term “Representatives”, as used in this Agreement (other than in Sections 2(d) and 7 and the second sentence of Section 3), shall mean the Initial Purchasers.

The holders of the Offered Securities, including the Initial Purchasers and their direct and indirect transferees, will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (the “Registration Rights Agreement”), among the Parent, the Guarantor and the Initial Purchasers, pursuant to which the Parent and the Guarantor will be required to file with the Securities and Exchange Commission (the “Commission”), under the circumstances set forth therein, (i) one or more registration statements under the Securities Act of 1933 (as amended, the “Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) relating to additional series of debt securities of the Parent with terms substantially identical to each series of the Offered Securities (the “Registered Securities”) to be offered in exchange for the Offered Securities (the “Exchange Offer”) and (ii) a shelf registration statement pursuant to Rule 415 under the Act relating to the resale by certain holders of the Offered Securities, and in each case, to use their commercially reasonable efforts to cause such registration statements to be declared effective.

In each case in exchange for a new series of Securities (the “Exchange Securities”) issued in exchange for all or a portion of a previously issued series of Securities, having identical terms to the Securities exchanged, subject to exceptions set forth in the Indenture and the Final Offering Memorandum, (as defined below), the Parent may cause, subject to certain conditions set forth in the Indenture, (i) ▇▇▇▇▇▇▇▇ 66 Company to issue Exchange Securities in exchange for Securities of the Parent, which Exchange Securities shall be guaranteed by the Parent, (ii) ▇▇▇▇▇▇▇▇ 66 Project Development Inc. (“PDI”) to issue Exchange Securities in exchange for Exchange Securities of ▇▇▇▇▇▇▇▇ 66 Company, which Exchange Securities shall be guaranteed by the Parent and ▇▇▇▇▇▇▇▇ 66 Company, and (iii) ▇▇▇▇▇▇▇▇ 66 Partners LP (“PSXP” and, along with ▇▇▇▇▇▇▇▇ 66 Company and PDI, each an “Eligible Exchange Securities Issuer”) to issue Exchange Securities in exchange for Exchange Securities of PDI, which Exchange Securities shall be guaranteed by the Parent and ▇▇▇▇▇▇▇▇ 66 Company.

The Parent understands that the Initial Purchasers propose to make an offering of the Offered Securities on the terms and in the manner set forth herein and in the Disclosure Package (as defined below) and agree that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Offered Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Disclosure Package (the first time when resales of the Securities are made, as set forth in any Terms Agreement referred to in Section 3 entered into in connection with a specified offering of the Offered Securities, is referred to as the “Execution Time”). The Parent acknowledges and agrees that the Initial Purchasers may offer and sell the Offered Securities to or through any affiliate of an Initial Purchaser and that any such affiliate may offer and sell the Offered Securities purchased by it to or through any Initial Purchaser. The Offered Securities are to be offered and sold to or by the Initial Purchasers without being registered with the Commission under the Act in reliance upon exemptions therefrom. Pursuant to the terms of the Offered Securities and the Indenture, investors who acquire Offered Securities shall be deemed to have agreed that Offered Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Act or if an exemption from the registration requirements of the Act is available (including the exemptions afforded by Rule 144A under the Act (“Rule 144A”) or Regulation S under the Act (“Regulation S”)).

In connection with each offering of Offered Securities, the Parent and the Guarantor will prepare and deliver to each Initial Purchaser copies of a preliminary offering memorandum (the “Preliminary Offering Memorandum”) and a pricing supplement (the “Pricing Supplement”) describing the terms of the Offered Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase or offering of the Offered Securities. “Disclosure Package” shall mean, with respect to any specific offering of the Offered Securities, (i) the Preliminary Offering Memorandum used most recently prior to the Execution Time and (ii) the Pricing Supplement identified in Schedule B to the Terms Agreement. Promptly after the Terms Agreement is executed and delivered, the Parent will prepare and deliver to each Initial Purchaser a final offering memorandum dated the date of such Terms Agreement (the “Final Offering Memorandum”).

The Parent hereby confirms that it has authorized the use of the Preliminary Offering Memorandum, the other materials contained in the Disclosure Package and the Final Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers in the manner contemplated by this Agreement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Preliminary Offering Memorandum.

2. Representations and Warranties of the Parent. The Parent, as of the Execution Time and as of the Closing Date, represents and warrants to, and agrees with, each Initial Purchaser that:

(a) No Registration. Subject to the accuracy of the representations and warranties of the Initial Purchasers set forth in the Terms Agreement referred to in Section 3 hereof and compliance by the Initial Purchasers with the procedures set forth in Section 6 hereof, it is not necessary in connection with the issuance, offer, sale and delivery of the Offered Securities to the Initial Purchasers and the offer, resale and delivery of the Offered Securities by the Initial Purchasers to each Subsequent Purchaser in the manner contemplated by this Agreement and the Preliminary Offering Memorandum, the Disclosure Package and the Final Offering Memorandum to register the Offered Securities under the Act or, until such time as the Registered Securities are issued pursuant to an effective registration statement, to qualify the Indenture under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder).

(b) No Similar Offerings or General Solicitations. None of the Parent, the Guarantor or any of their respective affiliates (as such term is defined in Rule 501(b) under the Act) (each, an “Affiliate”) or any person acting on their behalf (other than the Initial Purchasers, as to whom the Parent makes no representation or warranty) has, within the six-month period prior to the date of the Terms Agreement, directly or indirectly, sold, solicited any offer to buy or offered to sell or otherwise negotiated in respect of, or will, directly or indirectly, sell, solicit any offer to buy or offer to sell or otherwise negotiate in respect of, in the United States or to any United States citizen or resident (each as defined in Regulation S and collectively “U.S. Persons”), any security in a manner so as to cause such security to be integrated with the sale of the Offered Securities in a manner that would require the Offered Securities to be registered under the Act. None of the Parent, the Guarantor or any of their respective Affiliates or any person acting on their behalf (other than the Initial Purchasers, as to whom the Parent makes no representation or warranty) has engaged or will engage, in connection with the offering of the Offered Securities, in an offer to sell or in a solicitation of an offer to buy the Offered Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) under the Act or in a manner involving a public offering within the meaning of Section 4(a)(2) of the Act. With respect to those Offered Securities sold in reliance upon Rule 903 of Regulation S, (i) none of the Parent, the Guarantor or any of their respective Affiliates or any person acting on its or their behalf (other than the Initial

Purchasers, as to whom the Parent makes no representation or warranty) has engaged or will engage in an offer to sell or a solicitation of an offer to buy the Offered Securities by means of any “directed selling efforts” within the meaning of Rule 902(c) of Regulation S and (ii) each of the Parent, the Guarantor and their respective Affiliates and any person acting on their behalf (other than the Initial Purchasers, as to whom the Parent makes no representation or warranty) has complied and will comply with the offering restrictions set forth in Regulation S.

(c) Rule 144A Eligibility. The Offered Securities are eligible for resale pursuant to Rule 144A and will not be, at the Closing Date, of the same class as securities listed on a national securities exchange registered under Section 6 of the Securities Exchange Act of 1934 (as amended, the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) or quoted in any automated interdealer quotation system.

(d) Disclosure Package and Final Offering Memorandum. Neither the Disclosure Package, as of the Execution Time, nor the Final Offering Memorandum, as of its date or (as amended or supplemented in accordance with Section 4(a), as applicable) as of the Closing Date, contains or will contain an untrue statement of a material fact or omits or will 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; provided that this representation, warranty and agreement shall not apply to statements in or omissions from the Disclosure Package, the Final Offering Memorandum or any amendment or supplement thereto made in reliance upon and in conformity with information relating to any Initial Purchaser furnished to the Parent or its subsidiaries in writing by or on behalf of any Initial Purchaser through the Representatives expressly for use in the Disclosure Package, the Final Offering Memorandum or any amendment or supplement thereto, as the case may be, it being understood that the only such information consists of the information described in the Terms Agreement. The Disclosure Package contains, and the Final Offering Memorandum will contain, all the information specified in, and meeting the requirements of, Rule 144A(d)(4) under the Act. The Parent and its subsidiaries have not distributed and will not distribute, prior to the later of the Closing Date and the completion of the Initial Purchasers’ distribution of the Offered Securities, any offering material in connection with the offering and sale of the Securities other than the Disclosure Package, the Final Offering Memorandum and any electronic road show or other written communication used in accordance with Section 4(a) hereof.

(e) Additional Written Communications. The Parent, the Guarantor and their subsidiaries, including their agents and representatives (other than the Initial Purchasers, as to whom the Parent makes no representation or warranty), have not prepared, made, used, authorized, approved, referred to or distributed and will not prepare, make, use, authorize, approve, refer to or distribute any written communication that constitutes an offer to sell or solicitation of an offer to buy the Offered Securities other than (i) the Disclosure Package, (ii) the Final Offering Memorandum and (iii) any electronic road show or other written communications, in each case used in accordance with Section 4(a). Each such communication by the Parent, the Guarantor and their

subsidiaries or their respective agents and representatives pursuant to clause (iii) of the preceding sentence (each, a “Company Additional Written Communication”), when taken together with the Disclosure Package, did not as of the Execution Time, and at the Closing Date will not, conflict with the information contained in the Disclosure Package or the Final Offering Memorandum or contain any 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; provided that this representation, warranty and agreement shall not apply to statements in or omissions from each such Company Additional Written Communication made in reliance upon and in conformity with information furnished to the Parent or its subsidiaries in writing by or on behalf of any Initial Purchaser through the Representatives expressly for use in any Company Additional Written Communication, it being understood that the only such information consists of the information described in the Terms Agreement.

(f) No Conflicts. The execution, delivery and performance by the Parent and the Guarantor of the Indenture, the Offered Securities, the Guarantee, the Registration Rights Agreement and the Terms Agreement (including the provisions of this Agreement), as applicable, the issuance and sale of the Offered Securities by the Parent and of the Guarantee by the Guarantor and compliance by the Parent and the Guarantor with the terms and provisions thereof, and the issuance of Exchange Securities by each Eligible Exchange Securities Issuer and the guarantee thereof by the Parent and ▇▇▇▇▇▇▇▇ 66 Company and compliance with the terms and provisions thereof will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, (i) the Delaware General Corporation Law, the Delaware Revised Uniform Limited Partnership Act, the laws of the State of Texas or the federal laws of the United States that could reasonably be expected to have a material adverse effect on the condition (financial or otherwise), business, properties or results of operations of the Parent and its subsidiaries taken as a whole (a “Material Adverse Effect”), or (ii) any agreement or instrument to which the Parent, the Guarantor, PDI or PSXP is a party or by which the Parent, the Guarantor, PDI or PSXP is bound or to which any of the properties of the Parent, the Guarantor, PDI or PSXP is subject that could reasonably be expected to have a Material Adverse Effect, or (iii) the certificate of incorporation or certificate of limited partnership (as the case may be) or by-laws or agreement of limited partnership (as the case may be) of the Parent, the Guarantor, PDI or PSXP.

(g) No Violation or Default. Neither the Parent nor the Guarantor is (i) in violation of its certificate of incorporation or by-laws, (ii) in default under any agreement or instrument to which the Parent or the Guarantor is a party or by which the Parent or the Guarantor is bound or to which any of the properties of the Parent or the Guarantor is subject, or (iii) in violation of any law, ordinance, governmental rule or regulation or court decree to which it may be subject, which default or violation in the case of clause (ii) or (iii) could reasonably be expected to have a Material Adverse Effect.

(h) Financial Statements. The consolidated financial statements of the Parent, the Guarantor and their consolidated subsidiaries, together with the related notes thereto, included or incorporated by reference in the Disclosure Package and the Final Offering

Memorandum, present fairly the financial position of the Parent and its consolidated subsidiaries as of the dates shown and their results of operations and cash flows for the periods shown, and such financial statements comply in all material respects as to form with the accounting requirements of the Act and have been prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis throughout the periods involved, except as otherwise noted therein or as may be expressly stated in the related notes thereto.

(j) Anti-Corruption. Neither the Parent nor any of its consolidated subsidiaries, nor to the knowledge of the Parent or the Guarantor, any agent, director, officer, employee or other person associated with or acting on behalf of the Parent and its consolidated subsidiaries has, since May 1, 2012, (i) used any funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) made or taken an act in furtherance of an offer, promise or authorization of any direct or indirect unlawful payment or benefit to any foreign or domestic government or regulatory official or employee, including of any government-owned or controlled entity or of a public international organization, or any person acting in an official capacity for or on behalf of any of the foregoing, or any political party or party official or candidate for political office; (iii) violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, as amended, or any applicable law or regulation implementing the OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, or committed an offence under the ▇▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇ of the United Kingdom, or any other applicable anti-bribery or anti-corruption laws (collectively, the “Anti-Corruption Laws”); or (iv) made, offered, agreed, requested or taken an act in furtherance of any unlawful bribe or other unlawful benefit, including, without limitation, any rebate, payoff, influence payment, kickback or other unlawful or improper payment or benefit.

(l) Stabilization. Each of the Parent and the Guarantor has not taken and will not take, directly or indirectly, any action designed to, or that might reasonably be expected to, cause or result in stabilization or manipulation of the price of the Offered Securities or of any security of the Parent to facilitate the sale or resale of the Offered Securities.

3. Purchase and Offering of Offered Securities. The obligation of the Initial Purchasers to purchase the Offered Securities will be evidenced by an agreement or exchange of other written communications (“Terms Agreement”) at the time the Parent determines to sell the Offered Securities. The Terms Agreement will incorporate by reference the provisions of this Agreement, except as otherwise provided therein, and will specify the firm or firms which will be Initial Purchasers, the names of any Representatives, the principal amount of the Offered Securities to be purchased by each Initial Purchaser, the commission or fee to be paid to the Initial Purchasers and the terms of the Offered Securities not already specified in the Indenture, including, but not limited to, interest rate, maturity, any redemption provisions and any sinking fund requirements. The Terms Agreement will also specify the time and date of delivery and payment (such time and date or such other time not later than seven full business days thereafter as the Representatives and the Parent agree as the time for payment and delivery, being herein and in the Terms Agreement referred to as the “Closing Date”), the place of delivery and payment and any details of the terms of offering that should be reflected in the offering memorandum relating to the offering of the Offered Securities. For purposes of Rule 15c6-1 under the Exchange Act, the Closing Date (if later than the otherwise applicable settlement date) shall be the date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The obligations of the Initial Purchasers to purchase the Offered Securities will be several and not joint. It is understood that the Initial Purchasers propose to offer the Offered Securities for sale as set forth in the Final Offering Memorandum.

If the Terms Agreement specifies “Book-Entry Only” settlement or otherwise states that the provisions of this paragraph shall apply, the Parent will deliver against payment of the cash purchase price the Offered Securities in the form of one or more permanent global securities in definitive form (the “Global Securities”) deposited with the Trustee as custodian for The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., as nominee for DTC. The Global Securities will be made available for inspection by the Representatives not later than 5:00 pm, New York City time, on the business day prior to the Closing Date. Interests in any permanent global securities will be held only in book-entry form through DTC, except in the limited circumstances described in the Final Offering Memorandum. Payment for the Offered Securities shall be made by the Initial Purchasers in Federal (same day) funds by official check or checks or wire transfer to an account previously designated by the Parent at a bank acceptable to the Representatives, in each case drawn to the order of the Parent at the place of payment specified in the Terms Agreement on the Closing Date, against delivery to the Trustee as custodian for DTC of the Global Securities representing all of the Offered Securities.

4. Certain Agreements of the Parent. The Parent covenants and agrees with the several Initial Purchasers that, in connection with each offering of Offered Securities:

(a) Amendments or Supplements. As promptly as practicable following the Execution Time and in any event not later than the second business day following the date hereof, the Parent will prepare and deliver to the Initial Purchasers the Final Offering Memorandum, which shall consist of the Preliminary Offering Memorandum as modified only by the information contained in the Pricing Supplement. The Parent will not finalize the Final Offering Memorandum, amend or supplement the Preliminary Offering Memorandum, the Pricing Supplement or any other materials contained in the Disclosure Package and will not amend or supplement the Final Offering Memorandum prior to the Closing Date, in each case unless the Representatives shall previously have been furnished a copy of the proposed Final Offering Memorandum, amendment or supplement and shall not have objected to the Final Offering Memorandum or such amendment or supplement. Before making, preparing, using, authorizing, approving or distributing any Company Additional Written Communication, the Parent will furnish to the Representatives a copy of such written communication for review and will not make, prepare, use, authorize, approve or distribute any such written communication to which the Representatives reasonably object.

(b) Notice and Effect of Material Events; Ongoing Compliance of Offering Memorandum.

(i) If at any time prior to the Closing Date (x) any event shall occur or condition shall exist as a result of which the Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (y) it is necessary to amend or supplement the Disclosure Package to comply with law, the Parent and the Guarantor will immediately notify the Initial Purchasers thereof and forthwith prepare and (subject to Section 4(a) hereof) furnish, at their own expense, to the Initial Purchasers such amendments or supplements to the Disclosure Package as may be necessary so that the statements in the Disclosure Package as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or so that the Disclosure Package will comply with all applicable law.

(ii) If, prior to the completion of the placement of the Offered Securities by the Initial Purchasers with the Subsequent Purchasers, (x) any event shall occur or condition shall exist as a result of which the Final Offering Memorandum as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances when the Final Offering Memorandum is delivered to a Subsequent Purchaser, not misleading or (y) it is necessary to amend or supplement the Final Offering Memorandum to comply with law, the Parent and the Guarantor will immediately notify the Initial Purchasers thereof and forthwith prepare and (subject to Section 4(a) hereof)

furnish, at their own expense, to the Initial Purchasers such amendments or supplements to the Final Offering Memorandum, as may be necessary so that the statements in the Final Offering Memorandum as so amended or supplemented will not, in the light of the circumstances at the time of sale of the Offered Securities, be misleading or so that the Final Offering Memorandum, as so amended or supplemented, will comply with all applicable law.

(iii) The Parent will advise the Representatives promptly, and confirm such advice in writing, (x) of the issuance by any governmental or regulatory authority of any order preventing or suspending the use of any of the Disclosure Package or the Final Offering Memorandum or the initiation or threatening of any proceeding for that purpose and (y) of the receipt by the Parent of any notice with respect to any suspension of the qualification of the Offered Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Parent will use its commercially reasonable efforts to prevent the issuance of any such order preventing or suspending the use of any of the Disclosure Package or the Final Offering Memorandum or suspending any such qualification of the Offered Securities and, if any such order is issued, will use its commercially reasonable efforts to obtain as soon as possible the withdrawal thereof.

The Parent hereby expressly acknowledges that the indemnification and contribution provisions of Section 7 hereof are specifically applicable and relate to each offering memorandum, amendment or supplement referred to in this Section 4.

(c) Delivery of Copies. As promptly as practicable, the Parent agrees to furnish the Initial Purchasers, without charge, as many copies of the Preliminary Offering Memorandum and other materials contained in the Disclosure Package, the Final Offering Memorandum, any Company Additional Written Communication and any amendments or supplements thereto as they may reasonably request.

(d) DTC, Euroclear and Clearstream. The Parent will cooperate with the Initial Purchasers and use its best efforts to permit the Offered Securities to be eligible for clearance and settlement through the facilities of the Depositary, Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking société anonyme (“Clearstream”).

(e) Rule 144A Information. While the Offered Securities remain outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Act, the Parent and the Guarantor will, during any period in which the Parent is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act, furnish to holders of the Offered Securities and prospective purchasers of the Offered Securities designated by such holders, upon the request of such holders or such prospective purchasers, the information required to be delivered pursuant to Rule 144A(d)(4) under the Act.

(f) No Resales by the Parent. The Parent will not, and will not permit any of its affiliates (as defined in Rule 144 under the Act) to, resell any of the Offered Securities that have been reacquired by any of them.

(g) Legend. Each certificate for an Offered Security will bear the legend contained in “Transfer Restrictions” in the Preliminary Offering Memorandum for the time period and upon the other terms stated in the Preliminary Offering Memorandum.

(h) Blue Sky Compliance. The Parent will use its commercially reasonable efforts to arrange for the qualification of the Offered Securities for offer and sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution of the Offered Securities; provided, however, that neither the Parent nor ▇▇▇▇▇▇▇▇ 66 Company will be required in connection therewith to register or qualify as a foreign corporation where it would not otherwise be so qualified or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in any jurisdiction where it would not otherwise be so subject. The Parent will promptly advise the Representatives of the receipt by it or ▇▇▇▇▇▇▇▇ 66 Company of any notification with respect to the suspension of the qualification of the Offered Securities for offer and sale in any such jurisdiction or the initiation or threatening of any proceeding for such purpose.

Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Parent will pay all costs and expenses incident to the performance of its obligations under the Terms Agreement (including the provisions of this Agreement), for any filing fees or other expenses (including reasonable fees and disbursements of counsel) in connection with qualification of the Offered Securities for sale and determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate in accordance with Section 4(h) and the printing of memoranda relating thereto; any fees charged by investment rating agencies for the rating of the Offered Securities; any applicable filing fee incident to, and the reasonable fees and disbursements of counsel for the Initial Purchasers in connection with, the preparation of any Blue Sky memorandum and review by the Financial Industry Regulatory Authority, Inc., if any, of the terms of sale of the Offered Securities; any fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); any travel expenses of the Parent’s officers and employees and any other expenses of the Parent in connection with attending or hosting meetings with prospective purchasers of Securities; any costs incident to the issuance and delivery of the Offered Securities (including printing and engraving costs) and any necessary issue, transfer or other stamp taxes in that connection; all expenses and application fees incurred in connection with the application for the inclusion of the Offered Securities for book-entry transfer by DTC; and for expenses incurred in preparing, printing and distributing the Final Offering Memorandum, any preliminary offering memoranda or any other amendments or supplements to the Final Offering Memorandum to the Initial Purchasers. Except as provided in Section 4(i), Section 7 and Section 9 hereof, the Initial Purchasers shall pay their own expenses, including the fees and disbursements of counsel.

(j) Clear Market. The Parent will not, and will cause ▇▇▇▇▇▇▇▇ 66 Company not to, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to any United States dollar-denominated debt securities issued or guaranteed by the Parent or ▇▇▇▇▇▇▇▇ 66 Company and having a maturity of more than one year from the date of issue or any security convertible into or exchangeable or exercisable for any such debt security, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the Representatives, for a period beginning at the time of execution of the Terms Agreement and ending the number of days after the Closing Date specified under “Blackout” in the Terms Agreement (other than as contemplated by this Agreement and to register the Registered Securities).

(k) Pricing Supplement. The Parent will prepare the Pricing Supplement, containing solely a description of the terms of the Offered Securities and the offering thereof, in the form approved by the Representatives. The Parent consents to the use by any Initial Purchaser of an additional writing that (i) is not a Company Additional Written Communication and (ii) contains only information (A) describing the preliminary offering terms of the Offered Securities or their offering or information that describes the final terms of the Offered Securities or their offering and (B) that is included in the Pricing Supplement.

(i) in their opinion the financial statements and any schedules audited by them and included or incorporated by reference in the Final Offering Memorandum and the Disclosure Package comply as to form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related published Rules and Regulations adopted by the SEC;

(ii) they have performed the procedures specified by the Public Company Accounting Oversight Board for a review of interim financial information as described in AU722, Interim Financial Information, on any unaudited financial statements included in the Disclosure Package or the Final Offering Memorandum;

(iii) on the basis of the review referred to in clause (ii) above, a reading of the latest available interim financial statements of the Parent, inquiries of officials of the Parent who have responsibility for financial and accounting matters and other specified procedures, nothing came to their attention that caused them to believe that:

(A) the unaudited financial statements, if any, included in the Disclosure Package or the Final Offering Memorandum do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published Rules and Regulations or any material modifications should be made to such unaudited financial statements for them to be in conformity with generally accepted accounting principles;

(B) if any unaudited “capsule” information is contained in the Disclosure Package or the Final Offering Memorandum, the unaudited consolidated total revenues, net income and net income per share amounts or other amounts constituting such “capsule” information and described in such letter do not agree with the corresponding amounts set forth in the unaudited consolidated financial statements or were not determined on a basis substantially consistent with that of the corresponding amounts in the audited statements of income;

(C) if (and only if) any consolidated balance sheet for the Parent is available for any period subsequent to the latest consolidated balance sheet included in the Disclosure Package or the Final Offering Memorandum, at the date of the latest available consolidated balance sheet of the Parent read by such accountants, there was any change in the capital stock, any increase in total debt, any decrease in consolidated net current assets (working capital) or any decrease in stockholders’ equity, as compared with amounts shown on the latest consolidated balance sheet included in the Disclosure Package or the Final Offering Memorandum;

(D) at a subsequent specified date not more than three business days prior to the date of such letter, there was any change greater than 1% in the capital stock, or any increase greater than 1% in total debt, as compared with the latest available consolidated balance sheet; or

(E) if (and only if) any income statement for the Parent is available for any period subsequent to the latest consolidated balance sheet included in the Disclosure Package or the Final Offering Memorandum, for the period from the closing date of the latest income statement included in the Disclosure Package or the Final Offering Memorandum to the closing date of the latest available income statement read by such accountants there were any decreases, as compared with the corresponding period of the previous year and with the period of corresponding length ended the date of the latest income statement included in the Disclosure Package or the Final Offering Memorandum, in consolidated total revenues or net income;

except in all cases set forth in clauses (C), (D) and (E) above for changes, increases or decreases which the Disclosure Package and the Final Offering Memorandum discloses have occurred or may occur or which are described in such letter;

(iv) they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial information contained in the Final Offering Memorandum and the Disclosure Package (in each case to the extent that such dollar amounts, percentages and other financial information are derived from the general accounting records of the Parent and its subsidiaries subject to the internal controls of the Parent’s accounting system or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial information to be in agreement with such results, except as otherwise specified in such letter; and

(v) they have read any pro forma financial information which is included in the Disclosure Package or the Final Offering Memorandum and performed the additional procedures contemplated by Example D of Statement of Auditing Standards No. 72.

(e) Opinion and Statement of Internal Counsel for the Parent. The Representatives, on behalf of the Initial Purchasers, shall have received an opinion and statement, dated the Closing Date, of ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇, Deputy General Counsel for the Parent, to the effect that:

(i) the Parent is duly qualified to do business as a foreign corporation in good standing in all jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect;

(ii) the Parent has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Disclosure Package and the Final Offering

Memorandum and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect; all of the issued shares of capital stock of ▇▇▇▇▇▇▇▇ 66 Company have been duly and validly authorized and issued and are fully paid and non-assessable; except as set forth in the Final Offering Memorandum, all of the issued shares of capital stock of ▇▇▇▇▇▇▇▇ 66 Company, where applicable, are owned directly or indirectly by the Parent, free and clear of all liens, encumbrances, equities or claims;

(iii) the execution, delivery and performance by the Parent and ▇▇▇▇▇▇▇▇ 66 Company, as applicable, of the Indenture, the Registration Rights Agreement, the Offered Securities, the Guarantee and the Terms Agreement (including the provisions of this Agreement) and the issuance and sale of the Offered Securities and the Guarantee by the Parent and ▇▇▇▇▇▇▇▇ 66 Company, as applicable, the performance by the Parent and ▇▇▇▇▇▇▇▇ 66 Company under the Indenture, and compliance by the Parent and ▇▇▇▇▇▇▇▇ 66 Company, as applicable, with the terms and provisions thereof will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any agreement or instrument to which the Parent or ▇▇▇▇▇▇▇▇ 66 Company is a party or by which the Parent or ▇▇▇▇▇▇▇▇ 66 Company is bound or to which any of the properties of the Parent or ▇▇▇▇▇▇▇▇ 66 Company is subject, in each case to the extent that such breach, violation or default could reasonably be expected to have a Material Adverse Effect, or the charter or by-laws of the Parent or ▇▇▇▇▇▇▇▇ 66 Company;

(iv) the descriptions in the Final Offering Memorandum of statutes, legal and governmental proceedings and contracts and other documents are accurate in all material respects and fairly present the information required to be shown; and

(v) such counsel does not know of any legal or governmental proceedings pending or threatened to which the Parent or any of its subsidiaries is a party or to which any of the properties of the Parent or any of its subsidiaries is subject that, in such counsel’s judgment, are required to be described in the Final Offering Memorandum and are not so described or of any contracts or other documents that are required to be described in the Final Offering Memorandum that are not described or filed as required.

Such counsel shall also state that such counsel has participated in conferences with officers and other representatives of the Parent, representatives of the independent registered public accounting firm of the Parent, representatives of the Initial Purchasers and counsel to the Initial Purchasers at which the contents of the Final Offering Memorandum and the Disclosure Package were discussed and, although such counsel did not independently verify such information and is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Final Offering Memorandum and the Disclosure Package, on the basis of the foregoing no facts came to such counsel’s attention that led such counsel to believe that the Final Offering Memorandum (other than the financial statements and schedules, the

notes thereto and the auditors’ report thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need not comment) as of its date or as of the Closing Date 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 that the Disclosure Package (other than the financial statements and schedules, the notes thereto and the auditors’ report thereon, management’s report on internal control over financial reporting, if any, and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need not comment) as of the Execution 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.

(f) Opinion of Counsel for the Initial Purchasers. The Representatives, on behalf of the Initial Purchasers, shall have received from Cravath, Swaine & ▇▇▇▇▇ LLP, counsel for the Initial Purchasers, such opinion or opinions, dated the Closing Date, with respect to the incorporation of the Parent and the Guarantor, the validity of the Offered Securities, the Final Offering Memorandum, the Disclosure Package and other related matters as the Representatives may require, and the Parent and the Guarantor shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(g) Officers’ Certificate. The Representatives, on behalf of the Initial Purchasers, shall have received a certificate, dated the Closing Date, of the President or any Vice President and a principal financial or accounting officer or Treasurer of the Parent in which such officers, to the best of their knowledge after reasonable investigation, shall state that the representations and warranties of the Parent in this Agreement are true and correct, that each of the Parent and the Guarantor has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date, that, subsequent to the date of the most recent financial statements of the Parent incorporated by reference in the Final Offering Memorandum, there has been no material adverse change, nor any development or event involving a prospective material adverse change, in the condition (financial or other), business, properties or results of operations of the Parent and its subsidiaries taken as a whole except as set forth in or contemplated by the Disclosure Package and the Final Offering Memorandum or as described in such certificate.

(h) Bringdown Comfort Letters. The Representatives, on behalf of the Initial Purchasers, shall have received letters, dated the Closing Date, of Ernst & Young LLP and Deloitte & Touche LLP, as applicable, which meet the requirements of subsections (a) and (b) of this Section, except that the specified date referred to in such subsections will be a date not more than three days prior to the Closing Date for the purposes of this subsection.

(i) The Parent will furnish the Representatives with such conformed copies of such opinions, certificates, letters and documents as the Representatives reasonably request. The Representatives may in their sole discretion waive on behalf of the Initial Purchasers compliance with any conditions to the obligations of the Initial Purchasers under this Agreement and the Terms Agreement.

6. Offer, Sale and Resale Procedures. Each of the Initial Purchasers, on the one hand, and the Parent and the Guarantor, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Offered Securities:

(a) Offers and sales of the Offered Securities will be made only by the Initial Purchasers or Affiliates thereof qualified to do so in the jurisdictions in which such offers or sales are made. Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be “qualified institutional buyers” (within the meaning of Rule 144A) or non-U.S. persons outside the United States to whom the offeror or seller reasonably believes offers and sales of the Offered Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Schedule C to the Terms Agreement, which Schedule C is hereby expressly made a part hereof.

(b) The Offered Securities will be offered by approaching prospective Subsequent Purchasers on an individual basis. No general solicitation or general advertising (within the meaning of Rule 502 under the Act) will be used in the United States in connection with the offering of the Securities.

(c) Upon original issuance by the Parent, and until such time as the same is no longer required under the applicable requirements of the Act, the Offered Securities (and all Exchange Securities and other securities issued in exchange therefor or in substitution thereof, other than the Registered Securities) shall bear the following legend:

“THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER ▇▇▇▇▇▇▇ ▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE

SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) INSIDE THE UNITED STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A UNDER THE ACT, (b) OUTSIDE THE UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR RULE 904 OF REGULATION S UNDER THE ACT, (c) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE ACT PROVIDED BY RULE 144 THEREUNDER (IF APPLICABLE) OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS), (2) TO THE COMPANY OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE. NO REPRESENTATION CAN BE MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR RESALE OF THE SECURITY EVIDENCED HEREBY.”

Following the resale of the Offered Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Parent or the Guarantor for any losses, damages or liabilities suffered or incurred by the Parent or the Guarantor, including any losses, damages or liabilities under the Act, arising from or relating to any resale or transfer of any Offered Security.

7. Indemnification and Contribution.

(a) Indemnification of the Initial Purchasers. The Parent will indemnify and hold harmless each Initial Purchaser, its partners, directors and officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which such Initial Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Memorandum, the Disclosure Package, any Company Additional Written Communication, the Final Offering Memorandum, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Initial Purchaser for any legal or other expenses reasonably incurred by such Initial Purchaser in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Parent will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Parent by any Initial Purchaser through the Representatives, if any, specifically for use therein, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the information described as such in the Terms Agreement.

(b) Indemnity of the Parent and the Guarantor. Each Initial Purchaser will severally and not jointly indemnify and hold harmless the Parent and ▇▇▇▇▇▇▇▇ 66 Company, their respective directors and officers and each person, if any, who controls the Parent or ▇▇▇▇▇▇▇▇ 66 Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Parent or ▇▇▇▇▇▇▇▇ 66 Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Memorandum, the Disclosure Package, any Company Additional Written Communication, the Final Offering Memorandum, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Parent by such Initial Purchaser through the Representatives, if any, specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Parent or ▇▇▇▇▇▇▇▇ 66 Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the information described as such in the Terms Agreement.

(c) Notice and Procedures. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify in writing the indemnifying party of the commencement thereof; but the omission so to notify in writing the indemnifying party (i) will not relieve it from liability under subsection (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Parent and the Guarantor, on the one hand and the Initial Purchasers on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Parent and the Guarantor, on the one hand and the Initial Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Parent and the Guarantor on the one hand and the Initial Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Parent bear to the total fees paid to (including any discounts and commissions received by) the Initial Purchasers. 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 Parent or the Initial Purchasers and the parties’ relative intent, knowledge, access to

information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it and distributed to the Subsequent Purchasers were offered to the Subsequent Purchasers exceeds the amount of any damages which 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

(e) Non-Exclusive Remedies. The obligations of the Parent under this Section shall be in addition to any liability which the Parent may otherwise have and shall extend, upon the same terms and conditions, to the partners, directors, officers and each person, if any, who controls any Initial Purchaser within the meaning of the Act; and the obligations of the Initial Purchasers under this Section shall be in addition to any liability which the respective Initial Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each director of the Parent or ▇▇▇▇▇▇▇▇ 66 Company and to each person, if any, who controls the Parent or ▇▇▇▇▇▇▇▇ 66 Company within the meaning of the Act.

(f) The Parent and the Initial Purchasers 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 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 in subsection (d) above.

8. Default of Initial Purchasers. If any Initial Purchaser or Initial Purchasers default in their obligations to purchase Offered Securities under the Terms Agreement (including the provisions of this Agreement) and the aggregate principal amount of Offered Securities that such defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the Representatives may make arrangements satisfactory to the Parent for the purchase of such Offered Securities by other persons, including any of the Initial Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Initial Purchasers shall be obligated severally, in proportion to their respective commitments under the Terms Agreement (including the provisions of this Agreement), to purchase the Offered Securities that such defaulting Initial Purchasers agreed but failed to purchase. If any Initial Purchaser or Initial Purchasers so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Representatives and the Parent for the purchase of such Offered

Securities by other persons are not made within 36 hours after such default, the Terms Agreement (including the provisions of this Agreement) will terminate without liability on the part of any non-defaulting Initial Purchaser and the Parent, except as provided in Section 9. As used in this Agreement, the term “Initial Purchaser” includes any person substituted for an Initial Purchaser under this Section. Nothing herein will relieve a defaulting Initial Purchaser from liability for its default.

9. Survival of Certain Representations and Obligations.

Furthermore, the Parent agrees that it is solely responsible for making its own judgments in connection with any offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Parent or ▇▇▇▇▇▇▇▇ 66 Company on related or other matters). The Parent agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Parent or the Guarantor, in connection with such offering or the process leading thereto.

All communications hereunder will be in writing and, if sent to the Initial Purchasers, will be mailed, delivered or sent by facsimile and confirmed to them at their address furnished to the Parent in writing for the purpose of communications hereunder or, if sent to the Parent, will be mailed, delivered or sent by facsimile and

16. Applicable Law. This Agreement and the Terms Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws.

17. Jurisdiction.

Execution Time: 5:00 p.m., New York City time, on the date hereof.

The respective principal amounts of the Offered Securities to be purchased by each of the Initial Purchasers are set forth opposite their names in Schedule A hereto.

The provisions of the Purchase Agreement are incorporated herein by reference. Capitalized terms used but not defined herein shall have the respective meanings given such terms in the Purchase Agreement.

Each of the Initial Purchasers severally and not jointly represents and warrants to, and agrees with, the Parent that:

(a) it will offer and sell Offered Securities only to (i) persons who it reasonably believes are “qualified institutional buyers” within the meaning of Rule 144A in transactions meeting the requirements of Rule 144A or (ii) upon the terms and conditions set forth in Schedule C hereto;

(b) it is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Act; and

(c) it will not offer or sell Offered Securities by any form of general solicitation or general advertising, including but not limited to the methods described in Rule 502(c) under the Act.

For purposes of Sections 2 and 7 of the Purchase Agreement, the only information furnished to the Parent by the Representatives on behalf of any Initial Purchaser for use in the Preliminary Offering Memorandum consists of the following information in the Preliminary Offering Memorandum furnished on behalf of each Initial Purchaser: the fifth and eighth paragraphs and the third sentence of the seventh paragraph under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum.

European Economic Area

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each Initial Purchaser has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of Offered Securities which are the subject of the offering contemplated by the Preliminary Offering Memorandum and the Final Offering Memorandum to the public in that Relevant Member State other than:

(a) to any legal entity which is a qualified investor as defined in the Prospectus Directive;

(b) to fewer than 150, natural or legal persons (other than qualified investors as defined in the Prospectus Directive), subject to obtaining the prior consent of the representatives for any such offer; or

provided that no such offer of the Offered Securities shall require the Parent, the Guarantor or any Initial Purchaser to publish a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of the Offered Securities to the public” in relation to any Offered 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 Offered Securities to be offered so as to enable an investor to decide to purchase or subscribe the Offered Securities , as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and 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 the Relevant Member State and the expression. “2010 PD Amending Directive” means Directive 2010/73/EU.

United Kingdom

Each 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 of 2000 (the “FSMA”)) received by it in connection with the issue or sale of the Offered Securities in circumstances in which Section 21(1) of the FSMA does not apply to ▇▇▇▇▇▇▇▇ 66 or ▇▇▇▇▇▇▇▇ 66 Company and it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.
