Company, to enter into and perform its obligations under this Agreement. Each of the Company and each Significant Subsidiary is duly qualified as a foreign corporation, limited liability company or limited partnership, as the case may be, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would, individually or in the aggregate, result in a Material Adverse Change. All of the issued and outstanding shares of capital stock, limited liability company interests or partnership interests, as the case may be, of each Significant Subsidiary have been duly authorized and validly issued, are fully paid and nonassessable and are owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim. The Company does not have any subsidiary not listed on Exhibit 21 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 which is required to be so listed. The subsidiaries listed on Annex II to this Agreement are the only Significant Subsidiaries of the Company.

     p) Capitalization and Other Capital Stock Matters.

     q) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. Neither the Company nor any of its Significant Subsidiaries is (i) in violation or in default (or, with the giving of notice or lapse of time or both, would be in default) (“Default”) under its charter, by-laws or similar organizational documents, (ii) in Default under any indenture, mortgage, loan or credit agreement, deed of trust, note, contract, franchise, lease or other agreement, obligation, condition, covenant or instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an “Existing Instrument”) or (iii) in violation of any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of its subsidiaries or any of its or their properties, as applicable, except, with respect to clauses (ii) and (iii) only, for such Defaults or violations as would not, individually or in the aggregate result in a Material Adverse Change.

As used herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time or both would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) issued by the Company, the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries.

     r) No Material Actions or Proceedings.

No material dispute with the employees of the Company or any of its subsidiaries exists or, to the knowledge of the Company is contemplated or threatened, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or its subsidiaries’ principal suppliers, contractors or customers, that could, individually or in the aggregate, result in a Material Adverse Change.

     t) Intellectual Property Rights. Except as set forth in the Disclosure Package Information and the Offering Memorandum, to the Company’s knowledge, the Company or its subsidiaries own or possess a valid right to use all patents, trademarks, service marks, trade names, copyrights, patentable inventions, trade secret, know-how and other intellectual property (collectively, the “Intellectual Property”) used by the Company or its subsidiaries in, and material to, the conduct of the Company’s and its subsidiaries’ business as now conducted or as proposed in the Disclosure Package Information and the Offering Memorandum to be conducted. Except as set forth in the Disclosure Package Information and the Offering Memorandum or as could not, individually or in the aggregate result in a Material Adverse Change, there is no infringement by third parties of any of the Company’s Intellectual Property and there are no legal or governmental actions, suits, proceedings or claims pending or, to the Company’s knowledge, threatened, against the Company (i) challenging the Company’s rights in or to any Intellectual Property, (ii) challenging the validity or scope of any Intellectual Property owned by the Company, or (iii) alleging that the operation of the Company’s business as now conducted infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of a third party, and the Company is unaware of any facts which would form a reasonable basis for any such claim.

Except as otherwise disclosed in the Disclosure Package Information and the Offering Memorandum, the Company and each of its subsidiaries has good and marketable title to all the properties and assets reflected as owned in the financial statements referred to in Section 1(n) above (or elsewhere in the Disclosure Package Information and the Offering Memorandum), in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, claims and other defects, except such as do not materially and adversely affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by the Company or such subsidiary. The real property, improvements, equipment and personal property held under lease by the Company or any subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary.

     w) Tax Law Compliance. The Company and its subsidiaries have filed all necessary federal, state, local and foreign income and franchise tax returns in a timely manner and have paid all taxes required to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them, except for any taxes, assessments, fines or penalties as may be being contested in good faith and by appropriate proceedings, except where a default to make such filings or payments would not result in a Material Adverse Change. The Company has made appropriate provisions in the applicable financial statements referred to in Section 1(n) above in respect of all federal, state, local and foreign income and franchise taxes for all current or prior periods as to which the tax liability of the Company or any of its subsidiaries has not been finally determined.

     y) Insurance. The Company and its subsidiaries are insured by recognized, financially sound and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for their businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and its subsidiaries against theft, damage, destruction, acts of vandalism and earthquakes. All policies of insurance 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; and 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 or defending under a reservation of rights clause; and neither the Company nor any such subsidiary has been refused any insurance coverage sought or applied for. The Company has no reason to believe that it or any subsidiary will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Change.

     z) No Price Stabilization or Manipulation.

     cc) Stock Options. With respect to the stock options (the “Stock Options”) granted pursuant to the stock-based compensation plans of the Company and its subsidiaries (the “Company Stock Plans”), (i) each Stock Option intended to qualify as an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), so qualifies, (ii) each grant of a Stock Option was duly authorized no later than the date on which the grant of such Stock Option was by its terms to be effective (the “Grant Date”) by all necessary corporate action, including, as applicable, approval by the board of directors of the Company (or a duly constituted and authorized committee thereof) and any required stockholder approval by the necessary number of votes or written consents, and the award agreement governing such grant (if any) was duly executed and delivered by each party thereto, (iii) each such grant was made in accordance with the terms of the Company Stock

citizens group, employee or otherwise, that alleges that the Company or any of its subsidiaries is in violation of any Environmental Law, except as would not, individually or in the aggregate, result in Material Adverse Change; (ii) there is no claim, action or cause of action filed with a court or governmental authority, no investigation with respect to which the Company has received written notice, and no written notice by any person or entity alleging potential liability for investigatory costs, cleanup costs, governmental responses costs, natural resources damages, property damages, personal injuries, attorneys’ fees or penalties arising out of, based on or resulting from the presence, or release into the environment, of any Material of Environmental Concern at any location owned, leased or operated by the Company or any of its subsidiaries, now or in the past (collectively, “Environmental Claims”), pending or, to the best of the Company’s knowledge, threatened against the Company or any of its subsidiaries or any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law, except as would not, individually or in the aggregate, result in a Material Adverse Change; (iii) to the best of the Company’s knowledge, there are no past, present or anticipated future actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release, emission, discharge, presence or disposal of any Material of Environmental Concern, that reasonably could result in a violation of any Environmental Law, require expenditures to be incurred pursuant to Environmental Law, or form the basis of a potential Environmental Claim against the Company or any of its subsidiaries or against any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law, except as would not, individually or in the aggregate, result in a Material Adverse Change; and (iv) neither the Company nor any of its subsidiaries is subject to any pending or threatened proceeding under Environmental Law to which a governmental authority is a party and which is reasonably likely to result in monetary sanctions of $100,000 or more.

     gg) Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review and the amount of its established reserves, the Company has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Change.

     hh) ERISA Compliance. The Company and its subsidiaries and any “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of which the Company or such subsidiary is a member. No “employee benefit plan” that is subject to Title IV of ERISA and that is established or maintained by the Company, its subsidiaries or their ERISA Affiliates, is in “endangered or critical status” or “at-risk status”, or has an “accumulated

funding deficiency” or is delinquent in the contribution of any “minimum required contribution” (all as defined in Section 430, 431 or 432 of the Internal Revenue Code). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan,” (ii) Sections 4971 or 4975 of the Internal Revenue Code, (iii) Section 4980B of the Internal Revenue Code with respect to the excise tax imposed thereunder or (iv) Section 412(a)(2)(B) of the Internal Revenue Code. Each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Internal Revenue Code has received a favorable determination letter from the Internal Revenue Service and nothing has occurred, whether by action or failure to act, which is reasonably likely to cause disqualification of any such employee benefit plan under Section 401(a) of the Internal Revenue Code.

     ii) Sarbanes-Oxley Compliance. There is and has been no failure on the part of the Company and any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes-Oxley Act”), including Section 402 related to loans and Sections 302 and 906 related to certifications.

     jj) Company’s Accounting System. The Company and its subsidiaries maintain effective “internal control over financial reporting,” as such term is defined in Rule 13a-15(f) under the Exchange Act.

     kk) Internal Controls and Procedures. The Company maintains 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 generally accepted accounting principles 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.

     ll) No Material Weakness in Internal Controls. Except as disclosed in the Disclosure Package Information and the Offering Memorandum or in any document incorporated by reference therein, since the end of the Company’s most recent audited fiscal year, there has been (i) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (ii) 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.

     mm) Disclosure Controls. The Company and its subsidiaries maintain an effective system of “disclosure controls and procedures” (as defined in Rule 13a-15(e) of the Exchange Act) that is designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, including controls and procedures designed to ensure that such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding

required disclosure. The Company and its subsidiaries have carried out evaluations of the effectiveness of their disclosure controls and procedures as required by Rule 13a-15 of the Exchange Act.

     nn) Accuracy of Exhibits. There are no franchises, contracts or documents which are required to be filed or incorporated by reference as exhibits to the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 or Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2011 and June 30, 2011 which have not been so filed or incorporated by reference as required under the Exchange Act.

     oo) Statistical and Market Data. Nothing has come to the attention of the Company that has caused the Company to believe that the statistical and market-related data included in the Disclosure Package Information and the Offering Memorandum is not based on or derived from sources that are reliable and accurate in all material respects.

     pp) Margin Rules. Neither the issuance, sale and delivery of the Notes nor the application of the proceeds thereof by the Company as described in the Disclosure Package Information and the Offering Memorandum will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors.

     qq) Rule 144A Eligibility. On the Closing Date, the Notes will not be of the same class as securities listed on a national securities exchange registered under Section 6 of the Exchange Act or quoted in an automated inter-dealer quotation system; and each of the Preliminary Offering Memorandum and the Offering Memorandum, as of its respective date, contains or will contain all the information that, if requested by a prospective purchaser of the Notes, would be required to be provided to such prospective purchaser pursuant to Rule 144A(d)(4) under the Securities Act.

     rr) No Integration. Neither the Company nor any of its affiliates (as defined in Rule 501(b) of Regulation D under the Securities Act (“Regulation D”)) has, directly or through any agent, sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of, any security (as defined in the Securities Act), that is or will be integrated with the sale of the Notes in a manner that would require registration of the Notes under the Securities Act.

     ss) No General Solicitation or Directed Selling Efforts. None of the Company or any of its affiliates or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no representation is made) has (i) solicited offers for, or offered or sold, the Notes by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act or (ii) engaged in any directed selling efforts within the meaning of Regulation S under the Securities Act (“Regulation S”), and all such persons have complied with the offering restrictions requirement of Regulation S.

     tt) Securities Law Exemptions. Assuming the accuracy of the representations and warranties of the Initial Purchasers contained in Section 2(c) (including Annex III hereto) and their compliance with their agreements set forth therein, it is not necessary, in connection with the issuance and sale of the Notes to the Initial Purchasers and the offer, resale and delivery of

the Notes by the Initial Purchasers in the manner contemplated by this Agreement, the Disclosure Package Information and the Offering Memorandum, to register the Notes under the Securities Act or to qualify the Indenture under the Trust Indenture Act.

     Any certificate signed by an officer of the Company and delivered to the Representatives or to counsel for the Initial Purchasers shall be deemed to be a representation and warranty by the Company to each Initial Purchaser as to the matters set forth therein.

     Section 2. Purchase, Sale and Delivery of the Notes.

          a) The Notes. The Company agrees to issue and sell to the several Initial Purchasers, severally and not jointly, all of the Notes upon the terms herein set forth. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Initial Purchasers agree, severally and not jointly, to purchase from the Company the aggregate principal amount of Notes set forth opposite their names on Schedule A at a purchase price of 99.146% of the principal amount of the 3.20% Senior Notes due 2021 payable on the Closing Date.

          b) The Closing Date. Delivery of certificates for the Notes in global form to be purchased by the Initial Purchasers and payment therefor shall be made at the offices of Vinson & Elkins L.L.P., 1001 Fannin Street, Suite 2500, Houston, Texas (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m., Houston time, on August 17, 2011, or such other time and date as the Initial Purchasers and the Company shall mutually agree (the time and date of such closing are called the “Closing Date”).

          c) Offering of the Notes. The Company understands that the Initial Purchasers intend to offer the Notes for resale on the terms set forth in the Disclosure Package Information. Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that (with respect to itself and each affiliate):

	a.		it is a qualified institutional buyer (a “QIB”) within the meaning of Rule 144A under the Securities Act (“Rule 144A”) and an accredited investor within the meaning of Rule 501(a) under the Securities Act;
	b.		it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Notes by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act; and
	c.		it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Notes as part of their initial offering except:

i.

within the United States to persons whom it reasonably believes to be QIBs in transactions pursuant to Rule 144A and in connection with each such sale, it has taken or will take reasonable steps to ensure that the purchaser of the Notes is aware that such sale is being made in reliance on Rule 144A; or

ii.

in accordance with the restrictions set forth in Annex III hereto.

     Each Initial Purchaser acknowledges and agrees that the Company and, for purposes of the opinions to be delivered to the Initial Purchasers pursuant to Sections 6(d) and 6(e), counsel for the Company and counsel for the Initial Purchasers, respectively, may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by the Initial Purchasers with their agreements, contained in paragraph (c) above (including Annex III hereto), and each Initial Purchaser hereby consents to such reliance.

     The Company acknowledges and agrees that the Initial Purchasers may offer and sell Notes to or through any affiliate of an Initial Purchaser and that any such affiliate may offer and sell Notes purchased by it to or through any Initial Purchaser, provided that the Initial Purchasers and each affiliate complies with the offering restrictions in this Agreement and the Offering Memorandum.

          d) Payment for the Notes. Payment for the Notes shall be made at the Closing Date by wire transfer of immediately available funds to the order of the Company.

     It is understood that the Representatives have been authorized, for their own accounts and for the accounts of the several Initial Purchasers, to accept delivery of and receipt for, and make payment of the purchase price for, the Notes that the Initial Purchasers have agreed to purchase. The Representatives may (but shall not be obligated to) make payment for any Notes to be purchased by any Initial Purchaser whose funds shall not have been received by the Representatives by the Closing Date for the account of such Initial Purchaser, but any such payment shall not relieve such Initial Purchaser from any of its obligations under this Agreement.

          e) Delivery of the Notes. The Company shall deliver, or cause to be delivered, to the Representatives for the accounts of the several Initial Purchasers the Notes at the Closing Date through the facilities of the Depositary, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Initial Purchasers.

     Section 3. Covenants of the Company.

     The Company covenants and agrees with each Initial Purchaser as follows:

          a) Delivery of Copies. The Company will deliver, without charge, to the Initial Purchasers as many copies of the Preliminary Offering Memorandum, any other Disclosure Package Information, any Issuer Written Communication and the Offering Memorandum (including all amendments and supplements thereto) as the Representatives may reasonably request.

          b) Offering Memorandum, Amendments or Supplements. Before finalizing the Offering Memorandum or making or distributing any amendment or supplement to any of the Disclosure Package Information or the Offering Memorandum or filing with the Commission any document that will be incorporated by reference therein, the Company will furnish to the

Representatives and counsel for the Initial Purchasers a copy of the proposed Offering Memorandum or such amendment or supplement or document to be incorporated by reference therein for review, and will not distribute any such proposed Offering Memorandum, amendment or supplement or file any such document with the Commission to which the Representatives reasonably object.

          c) Additional Written Communications. Before making, preparing, using, authorizing, approving or referring to any Issuer Written Communication, the Company will furnish to the Representatives and counsel for the Initial Purchasers a copy of such written communication for review and will not make, prepare, use, authorize, approve or refer to any such written communication to which the Representatives reasonably object.

          d) Notice to the Representatives. The Company will advise the Representatives promptly, and confirm such advice in writing, (i) of the issuance by any governmental or regulatory authority of any order preventing or suspending the use of any of the Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum or the initiation or threatening of any proceeding for that purpose; (ii) of the occurrence of any event at any time prior to the completion of the initial offering of the Notes as a result of which any of the Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when such Disclosure Package Information, Issuer Written Communication or the Offering Memorandum is delivered to a purchaser, not misleading; and (iii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Notes for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order preventing or suspending the use of any of the Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum or suspending any such qualification of the Notes and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

          e) Disclosure Package Information. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Disclosure Package Information 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 (ii) it is necessary to amend or supplement any of the Disclosure Package Information to comply with law, the Company will immediately notify the Initial Purchasers thereof and forthwith prepare and, subject to paragraph (b) above, furnish to the Initial Purchasers such amendments or supplements to any of the Disclosure Package Information (or any document to be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in any of the Disclosure Package Information as so amended or supplemented will not, in light of the circumstances under which they were made, be misleading or so that any of the Disclosure Package Information will comply with law.

          f) Ongoing Compliance of the Offering Memorandum. If at any time prior to the completion of the initial offering of the Notes (i) any event shall occur or condition shall exist as

a result of which the 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 existing when the Offering Memorandum is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Offering Memorandum to comply with law, the Company will immediately notify the Initial Purchasers thereof and forthwith prepare and, subject to paragraph (b) above, furnish to the Initial Purchasers such amendments or supplements to the Offering Memorandum (or any document to be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in the Offering Memorandum as so amended or supplemented (including such document to be incorporated by reference therein) will not, in the light of the circumstances existing when the Offering Memorandum is delivered to a purchaser, be misleading or so that the Offering Memorandum will comply with law.

          g) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Initial Purchasers to qualify or register the Notes for sale under (or obtain exemptions from the application of) the state securities or blue sky laws of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Notes. The Company shall not be required to qualify to transact business or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign business. The Company will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Notes for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

          h) Use of Proceeds. The Company shall apply the net proceeds from the sale of the Notes sold by it in the manner described under the caption “Use of Proceeds” in the Disclosure Package Information and the Offering Memorandum.

          i) Depositary. The Company will cooperate with the Initial Purchasers and use its best efforts to permit the Notes to be eligible for clearance and settlement through the facilities of the Depositary.

          j) Supplying Information. While the Notes remain outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company will, during any period in which the Company is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act, furnish to holders of the Notes and prospective purchasers of the Notes 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 Securities Act.

          k) Agreement Not to Offer or Sell Additional Securities. During the period commencing on the date hereof and ending on the business day following the Closing Date, the Company will not, without the prior written consent of the Representatives (which consent may be withheld at the sole discretion of the Representatives), directly or indirectly, sell, offer,

contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act in respect of, any debt securities of the Company similar to the Notes or securities exchangeable for or convertible into debt securities similar to the Notes (other than as contemplated by this Agreement with respect to the Notes).

          l) No Resales by the Company. The Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Notes that have been acquired by any of them, except for Notes purchased by the Company or any of its affiliates and resold in a transaction registered under the Securities Act.

          m) No Integration. Neither the Company nor any of its affiliates (as defined in Rule 501(b) of Regulation D) will, directly or through any agent, sell, offer for sale, solicit offers to buy or otherwise negotiate in respect of, any security (as defined in the Securities Act), that is or will be integrated with the sale of the Notes in a manner that would require registration of the Notes under the Securities Act.

          n) No General Solicitation or Directed Selling Efforts. None of the Company or any of its affiliates or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no covenant is given) will (i) solicit offers for, or offer or sell, the Notes by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act or (ii) engage in any directed selling efforts within the meaning of Regulation S, and all such persons will comply with the offering restrictions requirement of Regulation S.

          o) Final Term Sheet. The Company will prepare a final term sheet containing only a description of the Notes, in a form approved by the Initial Purchasers and attached as Exhibit B hereto (such term sheet, the “Final Term Sheet”).

          p) Compliance with Sarbanes-Oxley Act. The Company will comply with all applicable securities and other laws, rules and regulations, including, without limitation, the Sarbanes-Oxley Act, and use its best efforts to cause the Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act.

          q) No Manipulation of Price. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Notes.

     The Representatives, on behalf of the several Initial Purchasers, may, in their sole discretion, waive in writing the performance by the Company of any one or more of the foregoing covenants or extend the time for their performance.

     Section 4. Payment of Expenses. The Company agrees to pay all costs, fees and expenses incurred in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including without limitation (i) all

expenses incident to the issuance and delivery of the Notes (including all printing and engraving costs), (ii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Notes, (iii) all fees and expenses of the Company’s counsel, independent public or certified public accountants and other advisors to the Company, (iv) all costs and expenses incurred in connection with the preparation, printing, shipping and distribution of the Preliminary Offering Memorandum, any other Disclosure Package Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto), and this Agreement, the Indenture, the DTC Agreement and the Notes, (v) all filing fees, reasonable attorneys’ fees and expenses incurred by the Company or the Initial Purchasers in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Notes for offer and sale under the state securities or blue sky laws, and, if requested by the Initial Purchasers, preparing a “Blue Sky Survey” or memorandum, and any supplements thereto, advising the Initial Purchasers of such qualifications, registrations and exemptions, (vi) the fees and expenses of the Trustee, including the reasonable fees and disbursements of counsel for the Trustee in connection with the Indenture and the Notes, (vii) any fees payable in connection with the rating of the Notes with the ratings agencies, (viii) all fees and expenses (including reasonable fees and expenses of counsel) of the Company in connection with approval of the Notes by the Depositary for “book-entry” transfer, and (ix) all other fees, costs and expenses incurred in connection with the performance of its obligations hereunder for which provision is not otherwise made in this Section. Except as provided in this Section 4 and Sections 7, 9 and 10 hereof, the Initial Purchasers shall pay their own expenses, including the fees and disbursements of their counsel.

     Section 5. Certain Agreements of the Initial Purchasers. Each Initial Purchaser hereby represents and agrees that it has not and will not use, authorize use of, refer to, or participate in the planning for use of, any written communication that constitutes an offer to sell or the solicitation of an offer to buy the Notes other than (i) the Preliminary Offering Memorandum and the Offering Memorandum, (ii) a written communication that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including through incorporation by reference) in the Preliminary Offering Memorandum or the Offering Memorandum, (iii) any written communication listed on Annex I or prepared pursuant to Section 3(c) above (including any electronic road show), (iv) any written communication prepared by such Initial Purchaser and approved by the Company in advance in writing or (v) any written communication relating to or that contains the terms of the Notes and/or other information that was included (including through incorporation by reference) in the Preliminary Offering Memorandum or the Offering Memorandum.

The indemnity agreement set forth in this Section 9(a) shall be in addition to any liabilities that the Company may otherwise have.

     (b) Indemnification of the Company, its Directors and Officers. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering

Memorandum, any of the other Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser through the Representatives expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information furnished to the Company by any Initial Purchaser through the Representatives expressly for use in the Preliminary Offering Memorandum, any of the other Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the third paragraph, the fourth paragraph, and the first sentence of the fifteenth paragraph under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum. The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

     (c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 9 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by the Representatives and that all such reasonable fees and expenses shall be reimbursed as they are incurred). Upon receipt of notice from the

indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence, in which case the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

     (d) Settlements. The indemnifying party under this Section 9 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 9(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding 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.

     Section 10. Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Notes pursuant to this Agreement 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 Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Company, and the total discounts and commissions received by the Initial Purchasers, in each case as set forth on the front cover page of the Offering Memorandum bear to the aggregate initial offering price of the Notes as set forth on such cover. The relative

fault of the Company, on the one hand, and the Initial Purchasers, 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 the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

     The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 9(c), any reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

     The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 10 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 which does not take account of the equitable considerations referred to in this Section 10.

     Notwithstanding the provisions of this Section 10, no Initial Purchaser shall be required to contribute any amount in excess of the total discounts and commissions received by such Initial Purchaser in connection with the Notes purchased by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 10 are several, and not joint, in proportion to their respective purchase commitments as set forth opposite their names in Schedule A. For purposes of this Section 10, each director, officer, employee and agent of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

     Section 11. Default of One or More of the Several Initial Purchasers. If, on the Closing Date, any one or more of the several Initial Purchasers shall fail or refuse to purchase Notes that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes, which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Notes to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportion to the aggregate principal amounts of such Notes set forth opposite their respective names on Schedule A bears to the aggregate principal amount of such Notes set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Initial Purchasers, to purchase such Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Initial Purchasers shall fail or refuse to purchase such Notes and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement

shall terminate without liability of any party to any other party except that the provisions of Sections 4, 7, 9, 10 and 18 shall at all times be effective and shall survive such termination. In any such case, either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days in order that the required changes, if any, to the Preliminary Offering Memorandum, any of the other Disclosure Package Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or any other documents or arrangements may be effected.

     As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 11. Any action taken under this Section 11 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

     Section 12. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company if at any time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or the New York Stock Exchange, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the Financial Industry Regulatory Authority; (ii) a general banking moratorium shall have been declared by any of federal or New York authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving the United States, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Notes in the manner and on the terms described in the Disclosure Package Information or the Offering Memorandum or to enforce contracts for the sale of securities; (iv) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (v) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services. Any termination pursuant to this Section 12 shall be without liability of any party to any other party except as provided in Sections 4 and 7 hereof, and provided further that Sections 4, 7, 9, 10 and 18 shall survive such termination and remain in full force and effect.

     Section 13. No Fiduciary Duty. The Company acknowledges and agrees that: (i) the purchase and sale of the Notes pursuant to this Agreement, including the determination of the offering price of the Notes and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Initial Purchasers, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such

Initial Purchaser has advised or is currently advising the Company on other matters) and no Initial Purchaser has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Initial Purchasers have not provided any legal, investment, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

     This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Initial Purchasers with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Initial Purchasers with respect to any breach or alleged breach of agency or fiduciary duty.

     Section 14. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Initial Purchasers set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Initial Purchaser, the officers or employees of any Initial Purchaser, or any person controlling the Initial Purchaser, the Company, the officers or employees of the Company, or any person controlling the Company, as the case may be or (B) acceptance of the Notes and payment for them hereunder and (ii) will survive delivery of and payment for the Notes sold hereunder and any termination of this Agreement.

	a.		Such Initial Purchaser has offered and sold the Notes, and will offer and sell the Notes, (A) as part of their distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering of the Notes and the Closing Date, only in accordance with Regulation S under the Securities Act (“Regulation S”) or Rule 144A or any other available exemption from registration under the Securities Act.
	b.		None of such Initial Purchaser or any of its affiliates or any other person acting on its or their behalf has engaged or will engage in any directed selling efforts with respect to the Notes, and all such persons have complied and will comply with the offering restrictions requirement of Regulation S.
	c.		At or prior to the confirmation of sale of any Notes sold in reliance on Regulation S, such Initial Purchaser will have sent to each distributor, dealer or other person receiving a selling concession, fee or other remuneration that purchase Notes from it during the distribution compliance period a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering of the Securities and the date of original issuance of the Securities, except in accordance with Regulation S or Rule 144A or any other available exemption from registration under the Securities Act. Terms used above have the meanings given to them by Regulation S.”

d.
