Ladies and Gentlemen:

Helix Energy Solutions Group, Inc., a Minnesota corporation (the “Company”), proposes to issue and sell to the several purchasers named in Schedule A (the “Initial Purchasers”) $550,000,000 in aggregate principal amount of its 9.5% senior notes due 2016 (the “Notes”). Banc of America Securities LLC (“BAS”) has agreed to act as representative of the several Initial Purchasers (in such capacity, the “Representative”) in connection with the offering and sale of the Notes.

The Notes will be issued pursuant to an indenture (the “Indenture”) to be dated as of the Closing Date (as defined in Section 2), among the Company, the Guarantors (as defined below) and Xxxxx Fargo Bank, National Association, as trustee (the “Trustee”).

The Notes will be offered and sold to the Initial Purchasers without being registered under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”), in reliance upon an exemption therefrom.

Holders of the Notes (including the Initial Purchasers and their direct and indirect transferees) will be entitled to the benefits of a Registration Rights Agreement, dated the Closing Date, among the Company, the Guarantors, and the Initial Purchasers (the “Registration Rights Agreement”), pursuant to which the Company and the Guarantors will agree to file with the Securities and Exchange Commission (the “Commission”) under the circumstances set forth therein (i) a registration statement under the Securities Act relating to another series of debt securities of the Company with terms substantially identical to the Notes (the “Exchange Notes”) to be offered in exchange for the Notes (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes and, in each case, to use its best efforts to cause such registration statements to be declared effective.

The payment of principal of, premium, if any, and interest on the Notes and the Exchange Notes when and as the same becomes due and payable, will be fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by (i) each of the Company’s existing direct and indirect domestic Restricted Subsidiaries (as defined in the Indenture) other than the Non-Guarantor Restricted Subsidiary (as defined in the Indenture) and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes additional guarantees in accordance with the terms of the Indenture, and their respective successors and assigns (collectively, the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees attached thereto are herein collectively referred to as the “Securities” and the Exchange Notes and the Guarantees attached thereto are referred to herein collectively as the “Exchange Securities.”

This Agreement, the Indenture, the Securities, the Exchange Securities and the Registration Rights Agreement are referred to herein collectively as the “Operative Documents.”

Each of the Company and the Guarantors understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Commission under the Securities Act in reliance upon exemptions therefrom. The terms of the Securities and the Indenture will require that investors that acquire Securities expressly agree that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemption afforded by Rule 144A (“Rule 144A”) or Regulation S (“Regulation S”) thereunder).

The Company has prepared and delivered to each of the Initial Purchasers copies of the preliminary offering memorandum dated as of December 7, 2007 (the “Preliminary Offering Memorandum”) and copies of a pricing supplement, dated as of December 18, 2007 (the “Pricing Supplement”) setting forth information concerning the Company, the Securities and the Registration Rights Agreement (as defined below). The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the “Pricing Disclosure Package.” Promptly after this Agreement is executed and delivered, the Company will prepare and deliver to each Initial Purchaser copies of a final offering memorandum dated the date hereof (the “Offering Memorandum”).

All references herein to the terms “Pricing Disclosure Package” and “Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated

thereunder (the “Exchange Act”) prior to the Time of Sale and incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Offering Memorandum (as the case may be), and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Offering Memorandum.

The Company hereby confirms its agreements with the Initial Purchasers as follows:

Section 1. Representations and Warranties of the Company.

Each of the Company and the Guarantors, jointly and severally, hereby represents, warrants and covenants to each Initial Purchaser as follows that, as of the date hereof and as of the Closing Date:

(a) No Registration. Assuming the accuracy of the representations and warranties of the Initial Purchasers contained in Section 6 and their compliance with the agreements set forth therein, it is not necessary, in connection with the issuance and sale of the Securities to the Initial Purchasers, and the offer, resale and delivery of the Securities by the Initial Purchasers, in each case in the manner contemplated by this Agreement, the Indenture, the Pricing Disclosure Package and the Offering Memorandum, to register the Securities under the Securities Act or, until such time as the Exchange Securities are issued pursuant to an effective registration statement, to qualify the Indenture under the Trust Indenture Act of 1939, as amended, and the rules and regulations promulgated thereunder (the “Trust Indenture Act”)

(b) No Integration. Other than to the Initial Purchasers in connection with the transactions contemplated by this Agreement, about which no representation is made by the Company, none of the Company or any of its subsidiaries 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 Securities in a manner that would require registration under the Securities Act of the Securities.

(c) Rule 144A. No securities of the same class (within the meaning of Rule 144A(d)(3) under the Securities Act) as the Securities are listed on any national securities exchange registered under Section 6 of the Exchange Act, or quoted on an automated inter-dealer quotation system. The Company is subject to and in full compliance with the reporting requirements of Section 13 or Section 15(d) of the Exchange Act.

(d) Preliminary Offering Memorandum, Pricing Disclosure Package and Offering Memorandum. Each of the Company and the Guarantors hereby confirms that it has authorized the use of the Pricing Disclosure Package and the Offering Memorandum in connection with the offer and sale of the Securities by the Initial Purchasers. Each

document, if any, filed or to be filed pursuant to the Exchange Act and incorporated by reference in the Pricing Disclosure Package and the Offering Memorandum complied or will comply when it is filed in all material respects with the Exchange Act. Neither the Pricing Disclosure Package, as of the Time of Sale, nor the Offering Memorandum, as of its date or (as amended or supplemented in accordance with Section 3(a), as applicable) as of the Closing Date, contain, 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 under which they were made, not misleading; provided that the Company and the Guarantors make no representation or warranty as to statements or omissions made in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser through the Representative specifically for inclusion therein. The Company has not distributed and will not distribute, prior to the later of the Closing Date and the completion of the Initial Purchasers’ distribution of the Securities, any offering material in connection with the offering and sale of the Securities other than the Pricing Disclosure Package and the Offering Memorandum.

(e) Company Additional Written Communications. The Company (including its agents and representatives, other than the Initial Purchasers in their capacity as such) has not prepared, made, used, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any written communication that constitutes an offer to sell or solicitation of an offer to buy the Securities (each such communication by the Company or its agents and representatives (other than a communication referred to in clauses (i), (ii) and (iii) below) a “Company Additional Written Communication”) other than (i) the Pricing Disclosure Package, (ii) the Offering Memorandum and (iii) any electronic road show or other written communications, in each case used in accordance with Section 3(a). Each such Company Additional Written Communication, when taken together with the Pricing Disclosure Package, did not, and at the Closing Date will not, contain 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 under which they were made, not misleading; provided that the Company and the Guarantors make no representation or warranty with respect to any statements or omissions made in each such Company Additional Written Communication in reliance upon and in conformity with information relating to any Initial Purchaser furnished to the Company by any Initial Purchaser through the Representative expressly for inclusion therein.

(f) Offering Materials Furnished to Initial Purchasers. The Company has delivered to the Representative the Pricing Disclosure Package, the Company Additional Written Communications and the Offering Memorandum, as amended or supplemented, in such quantities and at such places as the Representative has reasonably requested for each of the Initial Purchasers.

(i) Authorization of the Securities and the Exchange Securities. The Notes have been duly authorized for issuance and sale pursuant to this Agreement and the Indenture; on the Closing Date, the Notes will be duly executed and issued by the Company and, when authenticated in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers pursuant to this Agreement (assuming due authentication of the Securities by the Trustee), will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and entitled to the benefits provided by the Indenture, except (a) as such enforceability may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other laws affecting creditors’ rights generally and (b) that the remedy of specific performance and injunctive and other forms of equitable relief are subject to certain equitable defenses and to the discretion of the court before which any proceeding therefor may be brought; and the Securities will conform in all material respects to the description thereof contained in each of the Pricing Disclosure Package and the Offering Memorandum. The Exchange Notes have been duly and validly authorized for issuance by the Company pursuant to this Agreement, the Indenture, the Registration Rights Agreement and the Exchange Offer; on the closing date of the Exchange Offer, the Exchange Securities will be duly executed and issued by the Company and, when authenticated in accordance with the terms of the Indenture (assuming due authentication of the Securities by the Trustee), will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and entitled to the benefits provided by the Indenture, except (a) as such enforceability may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other laws affecting creditors’ rights generally and (b) that the remedy of specific performance and injunctive and other forms of equitable relief are subject to certain equitable defenses and to the discretion of the court before which any proceeding therefor may be brought; and the Exchange Securities will conform in all material respects to the description thereof contained in each of the Pricing Disclosure Package and the Offering Memorandum. The Guarantees of the Notes and the Exchange

Notes have been duly authorized for issuance and sale pursuant to this Agreement and the Indenture; on the Closing Date or, in the case of the Guarantees of the Exchange Notes, the closing date of the Exchange Offer, the Guarantees will be duly executed by each of the Guarantors and, when the Securities have been authenticated in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers pursuant to this Agreement (assuming due authentication of the Securities by the Trustee), will constitute valid and binding agreements of the Guarantors, enforceable in accordance with their terms, except (a) as such enforceability may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other laws affecting creditors’ rights generally and (b) that the remedy of specific performance and injunctive and other forms of equitable relief are subject to certain equitable defenses and to the discretion of the court before which any proceeding therefor may be brought; and the Exchange Securities will conform in all material respects to the description thereof contained in each of the Pricing Disclosure Package and the Offering Memorandum.

(k) No Material Adverse Change. Except as otherwise disclosed in each of the Pricing Disclosure Package and the Offering Memorandum, subsequent to the date as of which information is given in the Preliminary Offering Memorandum: (i) there has been no material adverse change, or any development involving a prospective material adverse change that would reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business or operations, whether or not arising from transactions in the ordinary course of business, of the Company and its subsidiaries, considered as one entity (any such change is called a “Material Adverse Change”); (ii) the Company and its subsidiaries, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, nor entered into any material transaction or agreement; and (iii) there has been no dividend or distribution of any kind declared, paid or made by the Company or, except for dividends paid to the Company or other subsidiaries, any of its subsidiaries on any class of capital stock or repurchase or redemption by the Company or any of its subsidiaries of any class of capital stock.

(l) Independent Accountants. Xxxxx & Young LLP, who have expressed their opinion with respect to the financial statements (which term as used in this Agreement includes the related schedules and notes thereto) filed with the Commission and included in or incorporated by reference in the Pricing Disclosure Package and the Offering Memorandum, are independent public or certified public accountants as required by the Securities Act and the Exchange Act.

(m) Preparation of the Financial Statements. The financial statements included in or incorporated by reference in each of the Pricing Disclosure Package and the Offering Memorandum present fairly the consolidated financial position of the Company

and its consolidated subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. Such financial statements have been prepared in conformity with generally accepted accounting principles as applied in the United States applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. The financial data set forth in each of the Pricing Disclosure Package and the Offering Memorandum under the captions “Summary—Summary Financial Data”, “Selected Consolidated Financial Data” and “Capitalization” fairly present the information set forth therein on a basis consistent with that of the audited financial statements contained in each of the Pricing Disclosure Package and the Offering Memorandum.

(n) Incorporation and Good Standing of the Company and its Subsidiaries. Each of the Company and its subsidiaries has been duly organized and is validly existing and in good standing under the laws of the jurisdiction in which it is organized and has full power and authority to own, lease and operate its properties and to conduct its business as described in each of the Pricing Disclosure Package and the Offering Memorandum and, in the case of the Company and the Guarantors, to enter into and perform their obligations under this Agreement. Each of the Company and each subsidiary is duly qualified 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 not, individually or in the aggregate, result in a Material Adverse Change. All of the issued and outstanding capital stock or other equity interests of each subsidiary has been duly authorized and validly issued, is fully paid and non-assessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim, except as disclosed in each of the Pricing Disclosure Package and the Offering Memorandum. The Company does not own or control, directly or indirectly, any corporation, association or other entity that would be considered a “significant subsidiary” under the Exchange Act other than the subsidiaries listed in Exhibit 21.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

(o) No Stamp or Transfer Taxes. To the knowledge of the Company, there are no stamp or other issuance or transfer taxes or duties or other similar fees or charges required to be paid in connection with the execution and delivery of this Agreement or the issuance or sale by the Company of the Securities or the Exchange Securities.

(p) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. Neither the Company nor any of its subsidiaries is in violation of its respective charter or by-laws or other organizational documents, or is in default (or, with the giving of notice or lapse of time, would be in default) (“Default”) under any indenture, mortgage, loan or credit agreement, note, contract, franchise, lease or other instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound (including, without limitation, the credit agreement dated as of

July 3, 2006 among the Company, Banc of America, N.A., as administrative agent and as lender, and certain other lenders) or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an “Existing Instrument”), except for such Defaults as would not, individually or in the aggregate, result in a Material Adverse Change.

The Company’s execution, delivery and performance of the Operative Documents and consummation of the transactions contemplated thereby and by each of the Pricing Disclosure Package and the Offering Memorandum (i) have been duly authorized by all necessary action and will not result in any violation of the provisions of the charter or by-laws or other organizational documents of the Company or any subsidiary, (ii) will not conflict with or constitute a breach of, or Default or a Debt Repayment Triggering Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, or require the consent of any other party to, any Existing Instrument and (iii) will not result in any violation of any law, administrative regulation or administrative or court decree applicable to the Company or any subsidiary. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency, is required for the Company’s execution, delivery and performance of the Operative Documents and consummation of the transactions contemplated thereby and by each of the Pricing Disclosure Package and the Offering Memorandum, except (i) with respect to the transactions contemplated by the Registration Rights Agreement, as may be required under the Securities Act, the Trust Indenture Act and the rules and regulations promulgated thereunder and (ii) such as have been obtained or made by the Company and are in full force and effect under the Securities Act, applicable state securities or blue sky laws and from the Financial Industry Regulatory Authority (“FINRA”). 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 would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) 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.

(q) No Material Actions or Proceedings. There are no legal or governmental actions, suits or proceedings pending or, to the best of the Company’s knowledge, threatened (i) against or affecting the Company or any of its subsidiaries, (ii) which has as the subject thereof any officer or director of, or property owned or leased by, the Company or any of its subsidiaries or (iii) relating to environmental or discrimination matters, where in any such case (A) there is a reasonable possibility that such action, suit or proceeding might be determined adversely to the Company or such subsidiary and (B) any such action, suit or proceeding, if so determined adversely, would reasonably be expected to result in a Material Adverse Change or adversely affect the consummation of the transactions contemplated by this Agreement. No material labor dispute with the employees of the Company or any of its subsidiaries, or with the employees of any

principal supplier of the Company, exists or, to the best of the Company’s knowledge, is threatened or imminent.

(r) Intellectual Property Rights. The Company and its subsidiaries own, possess, license or have other rights to use, on reasonable terms, all trademarks, trade names, copyrights, domain names, licenses, trade secrets and patent rights (collectively, “Intellectual Property Rights”) reasonably necessary to conduct their businesses as now conducted; and the expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has received any notice of infringement or conflict with asserted Intellectual Property Rights of others, which infringement or conflict, if the subject of an unfavorable decision, would result in a Material Adverse Change. To the Company’s knowledge, there is no material infringement by third parties of any Intellectual Property Rights owned by or exclusively licensed to the Company. The Company is not a party to or bound by any options, licenses or agreements with respect to the Intellectual Property Rights of any other person or entity that are required to be set forth in the Preliminary Offering Memorandum or the Offering Memorandum if it were a registration statement on Form S-3 (including through incorporation by reference) and are not described in all material respects. None of the technology employed by the Company has been obtained or is being used by the Company in violation of any contractual obligation binding on the Company or, to the Company’s knowledge, any of its officers, directors or employees or otherwise in violation of the rights of any persons.

(s) All Necessary Permits, Etc. The Company and each subsidiary possess such valid and current certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct their respective businesses, and neither the Company nor any subsidiary has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material Adverse Change.

(t) Title to Properties. The Company and each of its subsidiaries has good and marketable title to all the properties and assets reflected as owned by each of them in the financial statements referred to in Section 1(m) hereof, in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, claims and other defects, except as otherwise disclosed in each of the Pricing Disclosure Package and the Offering Memorandum or such as do not, singly or in the aggregate, materially and adversely affect the value of such property and do not, singly or in the aggregate, 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, singly or in the aggregate, 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.

(u) Tax Law Compliance. The Company and its consolidated subsidiaries have filed all material federal, state and foreign income and franchise tax returns 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. The Company has made adequate charges, accruals and reserves in the financial statements referred to in Section 1(m) hereof in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of the Company or any of its consolidated subsidiaries has not been finally determined.

(v) Company and Guarantors Not Required to Register as an “Investment Company". The Company and the Guarantors have been advised of the rules and requirements under the Investment Company Act of 1940, as amended, and the rules and regulations promulgated thereunder (the “Investment Company Act”). The Company and the Guarantors are not, and, after receipt of payment for the Securities and application of the proceeds as described in each of the Pricing Disclosure Package and the Offering Memorandum, will not be, required to register as an “investment company” within the meaning of the Investment Company Act and will conduct its business in a manner so that they will not become subject to the Investment Company Act.

(w) Compliance with Reporting Requirements. The Company is subject to and in full compliance with the reporting requirements of Section 13 or Section 15(d) of the Exchange Act.

(x) Insurance. Each of 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 terrorism and vandalism. 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.

The Company will not amend or supplement the Offering Memorandum during the period beginning on the date hereof and ending on the date which is the earlier of nine months after the date hereof and the completion of the resale of the Securities by the Initial Purchasers (as notified by the Initial Purchasers to the Company) unless the Initial Purchasers shall previously have been furnished a copy of the proposed amendment or supplement at least two business days prior to the proposed use or filing, and shall not have objected to such amendment or supplement.

(b) Company Additional Written Communications. Before making, preparing, using, authorizing, approving or referring to any Company Additional Written Communication, the Company will furnish to the Representative and counsel for the Initial Purchasers a copy of such written communication for review and will not use any such written communication to which the Representative reasonably objects.

(c) Amendments and Supplements to the Offering Memorandum and Other Securities Act Matters. If, at any time prior to the earlier of nine months after the date hereof and the completion of the resale of the Securities by the Initial Purchasers (as notified by the Initial Purchasers to the Company), any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Offering Memorandum in order that the Offering Memorandum will not include an 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 at the time it is delivered to a purchaser, not misleading, or if in the opinion of the Representative or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Offering Memorandum to comply with law, the Company shall promptly notify the Initial Purchasers, prepare and furnish to the Initial Purchasers (or file with the Commission in case of documents incorporated by reference), subject to Section 3(a) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission.

Following the consummation of the Exchange Offer or the effectiveness of an applicable shelf registration statement and for so long as the Securities are outstanding if, in the judgment of the Initial Purchasers, the Initial Purchasers or any of their affiliates (as such term is defined in the Securities Act) are required to deliver a prospectus in connection with sales of, or market-making activities with respect to, the Securities, to periodically amend the applicable registration statement so that the information contained therein complies with the requirements of Section 10 of the Securities Act, to amend the applicable registration statement or supplement the related prospectus or the documents incorporated therein when necessary to reflect any material changes in the information provided therein so that the registration statement and the prospectus will not contain 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 as of the date the prospectus is delivered to a purchaser, not misleading and to provide the Initial Purchasers with copies of each amendment or supplement filed and such other documents as the Initial Purchasers may reasonably request.

None of the Company and the Guarantors shall be required to qualify as a foreign corporation 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 corporation. The Company will advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities 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, each of the Company and the Guarantors shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

(j) No Integration. The Company will not, and will cause its subsidiaries not to, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any “security” (as defined in the Securities Act) in a transaction that could be integrated with the sale of the Securities in a manner that would require the registration under the Securities Act of the Securities.

(k) Rule 144 Tolling. During the period of two years after the last Closing Date, 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 Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

On or before the Closing Date, the Representative and counsel for the Initial Purchasers shall have received such information, documents and opinions as they may reasonably require for the purposes of enabling them to pass upon the issuance and sale of the Securities as contemplated herein, or in order to evidence the accuracy of any of the representations and warranties, or the satisfaction of any of the conditions or agreements, herein contained.

If any condition specified in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Representative by notice to the Company at any time on or prior to the Closing Date, which termination shall be without liability on the part of any party to any other party, except that Section 4, Section 7, Section 8 and Section 9 shall at all times be effective and shall survive such termination.

Section 6. Representations, Warranties and Agreements of Initial Purchasers.

Each of the Initial Purchasers represents and warrants that it is a “qualified institutional buyer” (“QIB”), as defined in Rule 144A of the Securities Act, or an accredited investor within the meaning of Rule 501(a)(1) under the Securities Act. The Initial Purchasers agree with the Company that:

(a) The Securities have not been and will not be registered under the Securities Act in connection with the initial offering of the Securities.

(b) The Initial Purchasers are purchasing the Securities pursuant to a private sale exemption from registration under the Securities Act.

(c) The Securities have not been and will not be offered or sold by such Initial Purchasers or its affiliates acting on its behalf except in accordance with Rule 144A to persons whom the offeror or seller reasonably believe to be Qualified Institutional Buyers or non-U.S. persons outside the United States to whom the offeror or seller reasonably believes offers and sales of the Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Annex I hereto, which Annex I is hereby expressly made a part hereof.

(d) The Initial Purchasers will not offer or sell the Securities in the United States by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine or similar medium or broadcast over television or radio, or (ii) any seminar or meeting whose attendees have been invited by any general solicitation or general advertising in the United States.

(e) The Initial Purchasers have not offered or sold, and will not offer or sell, any Securities except to persons whom they reasonably believe to be a QIB.

Section 7. Reimbursement of Initial Purchasers’ Expenses.

If this Agreement is terminated by the Representative pursuant to Section 5, Section 10 or Section 11, or if the sale to the Initial Purchasers of the Securities on the Closing Date is not consummated because of any refusal, inability or failure on the part of the Company to perform any agreement herein or to comply with any provision hereof, the Company agrees to reimburse the Representative and the other Initial Purchasers (or such Initial Purchasers as have terminated this Agreement with respect to themselves), severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Representative and the Initial Purchasers in connection with the proposed purchase and the offering and sale of the Securities, including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

Section 8. Indemnification.

(a) Indemnification of the Initial Purchasers. Each of the Company and the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser or such 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 the Company), 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 Pricing Disclosure Package, any Company Additional Written Communication or the Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact, in each case, necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and to reimburse the Initial Purchasers and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by BAS) as such expenses are reasonably incurred by such Initial Purchaser or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representative expressly for use therein.

(b) Indemnification of the Company, each Guarantor, and each of their Directors and Officers. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each Guarantor, each of their directors, each of their officers and each person, if any, who controls the Company or any Guarantor 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, any Guarantor, or any such each 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 or alleged untrue statement of a material fact contained in the Pricing Disclosure Package, any Company Additional Written Communication or the Offering Memorandum (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, 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 therein in reliance upon and in conformity with written information furnished to the Company by the Representative expressly for use therein; and to reimburse the Company, any Guarantor and each such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, any Guarantor or 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 and the Guarantors hereby acknowledge that the only information that the Initial Purchasers have furnished to the Company expressly for use in the Pricing Disclosure Package, any Company Additional Written Communication and the Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in Schedule B; and the Initial Purchasers confirm that such statements are correct. The indemnity agreement set forth in this Section 8(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 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof may be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the failure to so notify the indemnifying party (i) will not relieve it from liability under paragraph (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, in any event, relieve the indemnifying party from any liability which it may have for contribution or any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. 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 promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. 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 8 for any legal or other expenses subsequently incurred by such indemnified party in

connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (BAS in the case of Section 8(b) and Section 9), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is 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 8(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 (x) 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 (y) 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 9. Contribution.

If the indemnification provided for in Section 8 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 and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities 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 and the

Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein 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 and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Company and the Guarantors, 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 or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company and the Guarantors, 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 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8(c) for purposes of indemnification.

The Company, the Guarantors, and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 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 9.

Notwithstanding the provisions of this Section 9, the Initial Purchasers shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to investors were offered to investors exceeds the amount of any damages which the Initial Purchasers have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each officer and employee 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 or any Guarantor, each officer of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantors.

Section 10. 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 Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase 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 proportions that the principal amount of Notes set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Notes set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Representative with the consent of the non-defaulting Initial Purchasers, to purchase the 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 the Notes and the aggregate principal amount of Securities 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 Representative 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 (other than a defaulting Initial Purchaser) to any other party except that the provisions of Section 4, Section 7, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representative 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 Pricing Disclosure Package, the Offering Memorandum 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 10. Any action taken under this Section 10 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

Section 11. Termination of this Agreement.

On or prior to the Closing Date this Agreement may be terminated by the Representative 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 by the Nasdaq National Market, or trading in securities generally on either the Nasdaq National 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 FINRA; (ii) a general banking moratorium shall have been declared by any federal or New York authority; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, 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 Representative is material and adverse and makes it impracticable to market the Securities in the manner and on the terms described in the Pricing Disclosure Package and the Offering Memorandum or to enforce contracts for the sale of securities; (iv) in the judgment of the Representative there shall have occurred any Material Adverse Change; or (v) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representative may, singly or in the aggregate, interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 10 shall be without liability on the part of (a) the Company or any Guarantor to any Initial Purchaser, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Representative and the Initial Purchasers pursuant to Sections 4 and 7 hereof, (b) any Initial Purchaser to the Company, or (c) of any party hereto to any other party except that the provisions of Sections 8 and 9 shall at all times be effective and shall survive such termination.

Section 12. Representations and Indemnities to Survive Delivery.

The respective indemnities, contribution, agreements, representations, warranties and other statements of the Company, the Guarantors, their respective officers, and the several Initial Purchasers set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation, or statement as to the result hereof, made by or on behalf of the Initial Purchasers, the Company, any Guarantor or any of its or their respective partners, officers or directors or any controlling person, as the case may be, (ii) acceptance of the Securities and payment for them hereunder and (iii) any termination of this Agreement.

This Agreement will inure to the benefit of and be binding upon the parties hereto, including any substitute Initial Purchasers pursuant to Section 10 hereof, and to the benefit of the employees, officers and directors and controlling persons referred to in Section 8 and Section 9, and in each case their respective successors, and no other person will have any right or obligation hereunder. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 8 and 9 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Initial Purchasers and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. The term “successors” shall not include any purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

Section 15. Partial Unenforceability.

The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

Section 16. Governing Law Provisions; Consent to Jurisdiction.

(a) Governing Law Provisions

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

(b) Consent to Jurisdiction

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

With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

(d) Judgment Currency.

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Initial Purchasers could purchase U.S. dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligations of the Company and each Guarantor in respect of any sum due from them to any Initial Purchaser shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by such Initial Purchaser of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Initial Purchaser may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Initial Purchaser hereunder, the Company and each Guarantor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Initial Purchaser against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Initial Purchaser hereunder, such Initial Purchaser agrees to pay to the Company and the Guarantors (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Initial Purchaser hereunder.

Section 17. No Advisory or Fiduciary Responsibility

Each of the Company and the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Company and the Guarantors are capable of evaluating and understanding and understand and accept 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 agent or fiduciary of the Company, Guarantors or their respective affiliates, stockholders, creditors or employees or any other party, (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or the Guarantors 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 or the Guarantors on other matters) or any other obligation to the Company and the Guarantors 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 the Guarantors and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship and (v) the Initial Purchasers have not provided any legal, accounting,

regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

Section 18. General Provisions.

This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto. The Table of Contents and the Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 8 and the contribution provisions of Section 9, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Sections 8 and 9 hereto fairly allocate the risks in light of the ability of the parties to investigate the Company, its affairs and its business in order to assure that adequate disclosure has been made in the Pricing Disclosure Package, any Company Additional Written Communication or the Offering Memorandum (and any amendments and supplements thereto), as required by the Securities Act and the Exchange Act.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

ANNEX I

Resale Pursuant to Regulation S or Rule 144A.

Each Initial Purchaser understands that:

Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or for the benefit or account of, a U.S. Person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act. Such Initial Purchaser agrees that, during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S.

Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a selling concession, fee or other remuneration during the 40-day restricted period referred to in Rule 903 of Regulation S , it will send to such distributor, dealer or person receiving a selling concession, fee or other remuneration 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 and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of your distribution at any time or (ii) otherwise until 40 days after the later of the date the Securities were first offered to persons other than distributors in reliance upon Regulation S and the Closing Date, except in either case in accordance with Regulation S under the Securities Act (or in accordance with Rule 144A under the Securities Act or to accredited investors in transactions that are exempt from the registration requirements of the Securities Act), and in connection with any subsequent sale by you of the Securities covered hereby in reliance on Regulation S under the Securities Act during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice to substantially the foregoing effect. Terms used above have the meanings assigned to them in Regulation S under the Securities Act.”
