Ladies and Gentlemen:

          Introductory. Inverness Medical Innovations, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”) $150,000,000 aggregate principal amount of its 7.875% senior unsecured notes due 2016 (the “Notes”). The Company’s obligations under the Notes and the Indenture (as defined below) will be, jointly and severally, unconditionally guaranteed (the “Guarantees”), on a senior unsecured basis, by each of the Subsidiaries (as defined below) listed on the signature pages hereto (collectively, the “Guarantors,” and, together with the Company, the “Issuers”). The Notes and the Guarantees are referred to herein as the “Securities.” The respective principal amounts of the Notes to be so purchased by the several Underwriters are set forth opposite their names in Schedule A hereto. The Notes are to be issued under an indenture as supplemented by a first supplemental indenture (collectively, the “Indenture”) each to be dated the Closing Date (as defined below), by and between the Issuers and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”).

          ▇▇▇▇▇▇▇▇▇ & Company, Inc. (“Jefferies”), ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. (“GS”) and ▇▇▇▇▇ Fargo Securities, LLC (“▇▇▇▇▇ Fargo”) have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Securities.

          The Issuers have prepared and filed with the Securities and Exchange Commission (the “Commission”) a shelf registration statement on Form S-3 (File No. 333 158542), and have prepared a base prospectus to be used in connection with the public offering and sale of the Securities. Such base prospectus, as modified and attached to the Preliminary Prospectus (as defined below) is referred to herein as the “Base Prospectus”. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it became automatically effective under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), including all documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securi-

ties Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), is called the “Registration Statement.” The Issuers’ preliminary prospectus supplement dated August 4, 2009 describing the Securities and the offering thereof, together with the Base Prospectus, is called the “Preliminary Prospectus,” and the Preliminary Prospectus and any other preliminary prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof and is made available by the Issuers and used prior to the filing of the Prospectus (as defined below), together with the Base Prospectus, is called a “preliminary prospectus.” As used herein, the term “Prospectus” shall mean the final prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof (the “Final Prospectus Supplement”), together with the Base Prospectus, in the form made available by the Issuers and first used by the Underwriters to confirm sales of the Securities or in the form first made available to the Underwriters by the Issuers to meet requests of purchasers pursuant to Rule 173 under the Securities Act. As used herein, “Applicable Time” is 5:45 p.m. (New York time) on August 5, 2009. As used herein, “free writing prospectus” means any “free writing prospectus” within the meaning set forth in Rule 405 under the Securities Act related to the offering of the Securities contemplated hereby, and “Time of Sale Prospectus” means the preliminary prospectus, as amended or supplemented immediately prior to the Applicable Time, together with the information and free writing prospectuses, if any, identified in Schedule B hereto. As used herein, the terms “Registration Statement,” “preliminary prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents incorporated and deemed to be incorporated by reference therein. All references in this Agreement to the Registration Statement, any preliminary prospectus, or the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

          All references in this Agreement to financial statements and schedules and other information which are “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are or are deemed to be incorporated by reference in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus, as the case may be, shall be deemed to mean and include the filing of any document under the Exchange Act which is or is deemed to be incorporated by reference in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus, as the case may be.

          This Agreement, the Notes, the Guarantees, and the Indenture are hereinafter sometimes referred to collectively as the “Note Documents.”

          The Issuers hereby confirm their respective agreements with the Underwriters as follows:

     Section 1. Representations and Warranties of the Issuers. The Issuers hereby represent and warrant to each Underwriter, as of the date of this Agreement, as of the Closing Date (as hereinafter defined) and jointly and severally covenant with each Underwriter, as follows:

          (a) Compliance with Registration Requirements. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), if any, and (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) made any offer relating to the Securities in reliance on the exemption of Rule 163 under the Securities Act, the Company was a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act.

          The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, which became effective on April 10, 2009. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the Company’s use of the automatic shelf registration form. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated or threatened by the Commission.

          Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities Act and, if filed by electronic transmission pursuant to ▇▇▇▇▇ (except as may be permitted by Regulation S-T under the Securities Act), was identical in all material respects to the copy thereof delivered by the Company to the Underwriters for use in connection with the offer and sale of the Securities. Each of the Registration Statement, and any post-effective amendment thereto, at the time it became effective and at all subsequent times through the Closing Date, complied and will comply in all material respects with the Securities Act and, at the time it became effective and as of the Closing Date (as defined in Section 2), did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, the Time of Sale Prospectus did not, and at the Closing Date, the Time of Sale Prospectus, will not, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, as amended or supplemented by the Company, if applicable, as of its date and at all subsequent times through the Closing Date, did not and 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. The representations and warranties set forth in the three immediately preceding sentences do not apply to statements in or omissions from the Registration Statement, or any post-effective amendment thereto, or the Prospectus or the Time of Sale Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by the Representatives to the Company consists of the information described in Section 8(b) below. There are no contracts or other documents required to be described in the Time of Sale Prospectus or the Prospectus or to be filed as exhibits to the Registration Statement which have not been described or filed as required.

          The Company is not an “ineligible issuer” in connection with the offering of the Securities pursuant to Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act including timely filing with the Commission or retention where required and legending, and each such free writing prospectus, as of its issue date and at all subsequent times through the Closing Date did not, does not and will not (i) include any information that conflicted, conflicts with or will conflict with the information contained in the Registration Statement, the Prospectus or any preliminary prospectus, including any document incorporated by reference therein, in each case not superseded or modified, or (ii) when taken together with the Time of Sale Prospectus contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Except for the free writing prospectuses, if any, identified in Schedule B hereto, and Road Shows, if any, furnished by the Company to you before first use and identified in Schedule C hereto, the Company has not prepared, used or referred to, and will not, without your prior consent, prepare, use or refer to, any free writing prospectus. “Road Show” means each “road show” (as defined in Rule 433 under the Securities Act), if any, related to the offering of the Securities contemplated hereby that is a “written communication” (as defined in Rule 405 under the Securities Act). Each Road Show that was prepared by or behalf of (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) or used or referred to by the Company as of its issue date and at all subsequent times through the Closing Date did not, does not and will not (i) include any information that conflicted, conflicts with or will conflict with the information contained in the Registration Statement, the Prospectus or any preliminary prospectus, including any document incorporated by reference therein, in each case not superseded or modified, or (ii) when taken together with the Time of Sale Prospectus contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

          (b) Offering Materials Furnished to Underwriters. The Company has delivered to the Representatives three complete manually signed copies of the Registration Statement, each amendment thereto, if any, and of each consent and certificate of experts filed as a part thereof, if any, and conformed copies of the Registration Statement, each amendment thereto (without exhibits), if any, and preliminary prospectuses, the Time of Sale Prospectus, the Prospectus, as amended or supplemented, and any free writing prospectus of the Company, in such quantities and at such places as the Representatives have reasonably requested for each of the Underwriters.

          (k) Preparation of the Financial Statements. The financial statements filed with the Commission as a part of the Registration Statement and included in the Time of Sale Prospectus and the Prospectus present fairly the consolidated financial position of the Company and its subsidiaries (or its applicable subsidiaries) as of and at the dates indicated and the results of their operations and cash flows for the periods specified. The supporting schedules included in the Registration Statement present fairly the information required to be stated therein. Such financial statements and supporting schedules 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. No other financial statements or supporting schedules are required to be included in the Registration Statement or any Applicable Prospectus. The financial data set forth in each Applicable Prospectus under the caption “Summary—Summary Consolidated Financial Information” fairly present the information set forth therein on a basis consistent with that of the audited financial statements contained in the Registration Statement and each Applicable Prospectus. The pro forma condensed financial statements of the Company and its subsidiaries and the related notes thereto included in the Time of Sale Prospectus and the Prospectus present fairly the information contained therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements and have been properly presented on the bases de-

scribed therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein. To the Company’s knowledge, no person who has been suspended or barred from being associated with a registered public accounting firm, or who has failed to comply with any sanction pursuant to Rule 5300 promulgated by the PCAOB, has participated in or otherwise aided the preparation of, or audited, the financial statements, supporting schedules or other financial data filed with the Commission as a part of the Registration Statement and included in any Applicable Prospectus.

          (l) Company’s Accounting System. The Company makes and keeps accurate books and records and maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles as applied in the United States and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

          (m) Incorporation and Good Standing of the Company and its Subsidiaries. Each of the Company and its subsidiaries has been duly incorporated or organized, as the case may be, and is validly existing as a corporation, partnership or limited liability company, as applicable, in good standing under the laws of the jurisdiction of its incorporation or organization and has the power and authority (corporate or other) to own, lease and operate its properties and to conduct its business as described in each Applicable Prospectus and, in the case of each Issuer, to enter into and perform its obligations under this Agreement. Each of the Company and the subsidiaries of the Company set forth on Schedule D attached hereto (each a “Subsidiary” and, collectively, the “Subsidiaries”) is duly qualified as a foreign corporation, partnership or limited liability company, as applicable, to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, result in a Material Adverse Change. Each “significant subsidiary” (as such term is defined in Rule 1-02 of Regulation S-X) of the Company is set forth on Schedule D attached hereto. All of the issued and outstanding capital stock or other equity or ownership interests of each Subsidiary wholly owned by the Company or any other Subsidiary have been duly authorized and validly issued, are (in the case of capital stock) 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 adverse claim other than (A) the security interests created by (1) that certain First Lien Credit Agreement dated as of June 26, 2007 among, inter alia, the Company, the lenders party thereto and General Electric Capital Corporation as administrative agent and (2) that certain Second Lien Credit Agreement dated as of June 26, 2007 among, inter alia, the Company, the lenders party thereto and General Electric Capital Corporation as administrative agent, in each case, including any notes, guarantees, collateral and security documents, instruments and agreements executed in connection therewith (the “Senior Credit Documents”) and (B) any other liens or security interests permitted by the Senior Credit Documents. The Company does not own or control, directly or

indirectly, any corporation, association or other entity other than (i) the subsidiaries listed in Exhibit 21 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2008 and the subsidiaries listed in Schedule D attached hereto and (ii) such other entities omitted from Exhibit 21 or Schedule D attached hereto which, when such omitted entities are considered in the aggregate as a single subsidiary, would not constitute a “significant subsidiary” within the meaning of Rule 1-02(w) of Regulation S-X. All subsidiaries of the Company that are guarantors of the Senior Credit Documents and organized under the laws of a state of the United States are Guarantors, other than Diamics, Inc. and SPDH, Inc.

          (n) Capitalization and Other Capital Stock Matters. The authorized, issued and outstanding capital stock of the Company is as set forth in each Applicable Prospectus in the Company’s balance sheet as of December 31, 2008 (other than for subsequent issuances, if any, pursuant to employee benefit plans described in the Time of Sale Prospectus or upon the exercise of outstanding options or warrants described in each Applicable Prospectus). All of the issued and outstanding shares of capital stock of the Company have been duly authorized and validly issued, are fully paid and nonassessable and have been issued in compliance with federal and state securities laws. None of the outstanding equity interests of the Company was issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. All outstanding options, warrants, preemptive rights, rights of first refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any capital stock of the Company are as set forth and accurately and fairly described, in all material respects, in each Applicable Prospectus. The description of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth in each Applicable Prospectus accurately and fairly presents, in all material respects, the information required to be shown with respect to such plans, arrangements, options and rights.

          (o) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. Neither the Company nor any of its subsidiaries is in violation of its charter or by-laws, partnership agreement or operating agreement or similar organizational document, as applicable, 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, any credit agreement, indenture, pledge agreement, security agreement or other instrument or agreement evidencing, guaranteeing, securing or relating to indebtedness of the Company or any of its subsidiaries), 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 Issuers’ execution, delivery and performance of this Agreement and the Indenture, the consummation by the Issuers of the transactions contemplated hereby and by each Applicable Prospectus and the issuance and sale of the Securities to be sold by the Issuers (i) have been duly authorized by all necessary corporate or other organizational action and will not result in any violation of the provisions of the charter or by-laws, partnership agreement or operating agreement or similar organizational document of the Company or any subsidiary, as applicable, (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 (other than requiring the consent of General Electric Capital Corporation as administrative agent under the respective Senior Credit Documents 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, except, with respect to clauses (ii) and (iii), for such conflicts, breaches, Defaults, Debt Repayment Triggering Events, liens, charges, encumbrances or violations as would not, individually or in the aggregate, result in a Material Adverse Change. 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 Issuers’ execution, delivery and performance of this Agreement and the consummation by the Issuers of the transactions contemplated hereby and by each Applicable Prospectus, except (1) such as have been obtained or made by the Company or the Trustee and are in full force and effect under the Securities Act or the Trust Indenture Act, (2) such as may be required under applicable state securities or blue sky laws and (3) such as may be required from the 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.

          (p) No Material Actions or Proceedings. Except as otherwise disclosed in each Applicable Prospectus, there are no legal or governmental actions, suits or proceedings pending or, to the Company’s knowledge, threatened (i) against or affecting the Company or any of its subsidiaries, (ii) which have 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) any such action, suit or proceeding, if determined adversely to the Company, such subsidiary or such officer or director, would reasonably be expected to result in a Material Adverse Change or, individually or in the aggregate, adversely affect the consummation of the transactions contemplated by this Agreement or (B) any such action, suit or proceeding is or would be material in the context of the sale of Securities. No material labor dispute with the employees of the Company or any of its Subsidiaries exists or, to the Company’s knowledge, is threatened or imminent.

          (q) Intellectual Property Rights. To the Company’s knowledge, the Company owns, possesses or can acquire on reasonable terms sufficient trademarks, servicemarks, trade names, patents, copyrights, and any registrations and applications for any of the foregoing, domain names, licenses, approvals, trade secrets, know-how, inventions, technology and other similar rights (collectively, “Intellectual Property Rights”) reasonably necessary to conduct its business as now conducted and as proposed to be conducted as set forth in each Applicable Prospectus (the “Business”). The operation of the Business by the Company, together with the Company’s use of the Intellectual Property Rights purported to be owned by, or exclusively licensed to, the Company and used by the Company in the Business (collectively, “Company Intellectual Property Rights”), does not infringe, misappropriate or otherwise violate the Intellectual Property Rights of any third party, other than the rights of any third party under any patent, and to the Company’s knowledge, the operation of the Business, together with the Company’s use of any Company Intellectual Property Rights, does not infringe or otherwise violate the

rights of any third party under any patent. Except as disclosed in each Applicable Prospectus, no actions, suits, claims or proceedings have been asserted or, to the knowledge of the Company, threatened against the Company alleging any of the forgoing or seeking to challenge, deny or restrict the operation of the Business by the Company, except for such actions, suits, claims or proceedings as would not, individually or in the aggregate, result in a Material Adverse Change. The Company has not received any written notice of a claim of infringement, misappropriation or conflict with Intellectual Property Rights of others, except for such claims, individually or in the aggregate, as would not result in a Material Adverse Change. Except as disclosed in each Applicable Prospectus or except as would not, individually or in the aggregate, be reasonably expected to result in a Material Adverse Change, no court, administrative body or arbitral body has issued any order, judgment, decree or injunction restricting the operation of the Business by the Company.

          Except as disclosed in each Applicable Prospectus or except as would not, individually or in the aggregate, be reasonably expected to result in a Material Adverse Change, the Company Intellectual Property Rights owned by the Company and, to the knowledge of the Company, any Intellectual Property Rights exclusively licensed to the Company have not been adjudged invalid or unenforceable, in whole or in part, and, except as aforesaid, there is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others challenging the validity or scope of any such Intellectual Property Rights. Except as disclosed in each Applicable Prospectus or except as would not, individually or in the aggregate, be reasonably expected to result in a Material Adverse Change, there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others challenging the Company’s right in or to any Company Intellectual Property Rights. Except as otherwise disclosed in each Applicable Prospectus, the Company is not a party to or bound by any agreements with respect to the Intellectual Property Rights of any other person or entity that are required to be set forth in each such Applicable Prospectus. None of the technology or intellectual property included in, or that is the subject matter of, the Company Intellectual Property Rights 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.

          Other than the patent applications acquired by the Company from a third party (the “Acquired Patent Applications”), the Company has duly filed or caused to be filed with the U.S. Patent and Trademark Office (the “PTO”) or foreign and international patent authorities all patent applications disclosed in each Applicable Prospectus as owned by the Company (the “Company Patent Applications”). The Company has complied with the PTO’s duty of candor and disclosure for the Company Patent Applications and has made no material misrepresentation during prosecution of the Company Patent Applications and the Acquired Patent Applications. To the Company’s knowledge, the Company Patent Applications disclose patentable subject matters and correctly name the inventors of the claimed subject matter. With respect to the Company Patent Applications, the Company has not been notified of any inventorship challenges nor has any interference been declared.

          The Company has used reasonable security measures, but in no event less than those efforts that would accord with normal industry practice, to maintain the confidentiality of the trade secrets and other confidential information included in the Company Intellectual Prop-

erty Rights. To the knowledge of the Company, all material trade secrets included in the Company Intellectual Property Rights are valid and protectible. Furthermore, to the knowledge of the Company, (i) there has been no misappropriation of any material trade secrets included in the Company Intellectual Property Rights by any other person, (ii) no employee, independent contractor or agent of the Company has misappropriated any trade secrets of any other person in the course of performance as an employee, independent contractor or agent of the Company, and (iii) no employee, independent contractor or agent of the Company is in material default or breach of any term of any employment agreement, nondisclosure agreement, assignment of invention agreement or similar agreement or contract relating in any way to the protection, ownership, development, use or transfer of Company Intellectual Property Rights owned by the Company.

          (r) 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, or has any reason to believe that it will receive, any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could result in a Material Adverse Change.

          (s) Title to Properties. Except as otherwise disclosed in each Applicable Prospectus, each of the Company and its subsidiaries has good and marketable title to all of the real and personal property and other assets reflected as owned in the financial statements referred to in Section 1(k) above (or elsewhere in any Applicable Prospectus), in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, adverse 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 and except for (A) the security interests created by the Senior Credit Documents and (B) any other liens or security interests permitted by the Senior Credit Documents. 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.

          (t) Tax Law Compliance. The Company and its subsidiaries have filed all necessary 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, except for such failure to file or pay as would not, individually or in the aggregate, result in a Material Adverse Change. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section 1(k) above 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.

          (u) Each Issuer Not an “Investment Company”. Each Issuer has been advised of the rules and requirements under the Investment Company Act of 1940, as amended (the “In-

vestment Company Act”). Each Issuer is not, and will not be, either after receipt of payment for the Securities or after the application of the proceeds therefrom as described under “Use of Proceeds” in each Applicable Prospectus, an “investment company” within the meaning of the Investment Company Act.

          (v) Insurance. The Company and its subsidiaries are insured by recognized 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 and policies covering the Company and its subsidiaries for product liability claims and clinical trial liability claims. 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, individually or in the aggregate, result in a Material Adverse Change. Neither the Company nor any subsidiary has been denied any insurance coverage which it has sought or for which it has applied.

          (w) No Price Stabilization or Manipulation; Compliance with Regulation M. No Issuer has taken, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Securities or any other “reference security” (as defined in Rule 100 of Regulation M under the 1934 Act (“Regulation M”)) whether to facilitate the sale or resale of the Securities or otherwise, or has taken any action which would directly or indirectly violate Regulation M.

The Company meets the requirements for use of Form S-3 under the Securities Act specified in Rule 5110(b)(7)(C)(i) of the Financial Industry Regulatory Authority (the “FINRA”).

          (z) Exchange Act Compliance. The documents incorporated or deemed to be incorporated by reference in each Applicable Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Exchange Act, and, when read together with the other information in each Applicable Prospectus, at the time the Registration Statement and any amendments thereto become effective and at the Closing Date will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

          (aa) Statistical and Market-Related Data. The statistical, demographic and market-related data included in the Registration Statement and each Applicable Prospectus are

based on or derived from sources that the Company believes to be reliable and accurate or represent the Company’s good faith estimates that are made on the basis of data derived from such sources.

          (bb) No Unlawful Contributions or Other Payments. Neither the Company nor any of its subsidiaries nor, to the Company’s knowledge, any employee or agent of the Company or any subsidiary, has made any contribution or other payment to any official of, or candidate for, any federal, state or foreign office in violation of any law or of the character required to be disclosed in the Registration Statement and each Applicable Prospectus.

          (cc) Disclosure Controls and Procedures; Deficiencies in or Changes to Internal Control Over Financial Reporting. The Company has established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)), which (i) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated by management of the Company for effectiveness as of a date within 90 days prior to the earlier of the date that the Company filed its most recent annual or quarterly report with the Commission and the date of the Time of Sale Prospectus; and (iii) are effective in all material respects to perform the functions for which they were established. There has not been and is no material weakness in the Company’s internal control over financial reporting since January 1, 2008, and since December 31, 2008, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company is not aware of any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting. The principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Company have made all certifications required by the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”) and any related rules and regulations promulgated by the Commission.

          (dd) Compliance with Environmental Laws. Except as described in each Applicable Prospectus and except as would not, individually or in the aggregate, result in a Material Adverse Change, (i) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (ii) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (iii) there are no pending or, to the Company’s knowledge, threatened administrative, regulatory or judicial ac-

tions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its subsidiaries and (iv) there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of its subsidiaries relating to Hazardous Materials or any Environmental Laws.

          (ee) ERISA Compliance. The Company and its subsidiaries and any “employee benefit plan” (as defined under 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 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). 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” or (ii) Sections 412, 4971, 4975 or 4980B of the 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 Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

          (ff) Brokers. Except for the underwriting discounts and commissions payable to the Underwriters as described in each Applicable Prospectus, there is no broker, finder or other party that is entitled to receive from the Company any brokerage or finder’s fee or other fee or commission as a result of any transactions contemplated by this Agreement.

          (gg) No Outstanding Loans or Other Extensions of Credit. Since the adoption of Section 13(k) of the Exchange Act, neither the Company nor any of its subsidiaries has extended or maintained credit, arranged for the extension of credit, or renewed any extension of credit, in the form of a personal loan, to or for any director or executive officer (or equivalent thereof) of the Company and/or such subsidiary except for such extensions of credit as are expressly permitted by Section 13(k) of the Exchange Act.

          (hh) Compliance with Laws. The Company and each of its subsidiaries are conducting business in compliance with all applicable laws, rules and regulations of the jurisdictions in which it is conducting business, except where failure to be so in compliance would not, individually or in the aggregate, result in a Material Adverse Change. The Company, its subsidiaries and, to the Company’s knowledge, the Company’s directors and officers are each in compliance in all material respects with all applicable effective provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act

and the rules and regulations of the Commission and the New York Stock Exchange promulgated thereunder.

          (ii) Dividend Restrictions. Except as otherwise described in each Applicable Prospectus and except as set forth in the Senior Credit Documents, no subsidiary of the Company is prohibited or restricted, directly or indirectly, from paying dividends to the Company, or from making any other distribution with respect to such subsidiary’s equity securities or from repaying to the Company or any other subsidiary of the Company any amounts that may from time to time become due under any loans or advances to such subsidiary from the Company or from transferring any property or assets to the Company or to any other subsidiary.

          (jj) Foreign Corrupt Practices Act. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee, affiliate or other person acting on behalf of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that has resulted or would result in a violation of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA; and the Company and its subsidiaries and, to the knowledge of the Company, the Company’s affiliates have conducted their respective businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably intended to continue to ensure, continued compliance therewith.

          (kk) Money Laundering Laws. The operations of the Company and its subsidiaries are, and have been conducted at all times, in compliance in all material respects with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar applicable rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened.

          (ll) OFAC. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee, affiliate or person acting on behalf of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

          (nn) Regulation T, U and X.

          Any certificate signed by any officer of the Company or any of its subsidiaries and delivered to the Representatives or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby.

The Issuers shall furnish to each Underwriter, without charge, as many copies of any free writing prospectus prepared by or on behalf of, or used by the Issuers, as such Underwriter may reasonably request. If at any time when a prospectus is required by the Securities Act (including, without limitation, pursuant to Rule 173(d)) to be deliv-

ered in connection with sales of the Securities (but in any event if at any time through and including the Closing Date) there occurred or occurs an event or development as a result of which any free writing prospectus prepared by or on behalf of, used by, or referred to by the Issuers conflicted or would conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Issuers shall promptly amend or supplement such free writing prospectus to eliminate or correct such conflict or so that the statements in such free writing prospectus as so amended or supplemented 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 prevailing at such subsequent time, not misleading, as the case may be; provided, however, that prior to amending or supplementing any such free writing prospectus, the Issuers shall furnish to the Representatives for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of such proposed amended or supplemented free writing prospectus, and the Issuers shall not file, use or refer to any such amended or supplemented free writing prospectus without the Representatives’ consent.

          (d) Filing of Underwriter Free Writing Prospectuses. The Issuers shall not take any action that would result in an Underwriter or the Issuers being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

          (e) Final Term Sheet. The Issuers will prepare a final term sheet (the “Final Term Sheet”) in the form of Exhibit B hereto reflecting the final terms of the Securities (and containing such other information as the Issuers shall deem necessary in order that the Time of Sale Prospectus shall not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements in the Time of Sale Prospectus, in the light of the circumstances under which they were made, not misleading), in form and substance reasonably satisfactory to the Representatives, and shall file such Final Term Sheet as an issuer free writing prospectus pursuant to Rule 433 under the Act prior to the close of business two business days after the date hereof; provided that the Issuers shall provide the Representatives with copies of any such Final Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object.

          (f) Amendments and Supplements to Time of Sale Prospectus. If the Time of Sale Prospectus is being used to solicit offers to buy the Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus so that the Time of Sale Prospectus does 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 when delivered to a prospective purchaser, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement, or if, in the reasonable opinion of counsel for the Underwriters, it is otherwise necessary to amend or supplement the Time of Sale Prospectus to comply

with applicable law, including the Securities Act, the Issuers shall (subject to Sections 3(b) and 3(c)) promptly prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented 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 when delivered to a prospective purchaser, not misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law, including the Securities Act.

          (g) Securities Act Compliance. After the date of this Agreement, through the last time that a prospectus is required by the Securities Act (including, without limitation, pursuant to Rule 173(d)) to be delivered in connection with sales of the Securities (but in any event at any time through and including the Closing Date), the Issuers shall promptly advise the Representatives in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (ii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus of the Company or the Prospectus, (iii) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any amendment or supplement to any preliminary prospectus, the Time of Sale Prospectus or the Prospectus or of any order preventing or suspending the use of any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing the Securities from any securities exchange upon which they are listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at any time through the last time that a prospectus is required by the Securities Act (including, without limitation, pursuant to Rule 173(d)) to be delivered in connection with sales of the Securities (but in any event at any time through and including the Closing Date), the Company will use its reasonable commercial efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the Company agrees that it shall comply with the provisions of Rule 424(b) and Rule 433, as applicable, under the Securities Act and will use its reasonable efforts to confirm that any filings made by the Company under such Rule 424(b) or Rule 433 were received in a timely manner by the Commission. If, after the date of this Agreement and through the last time that a prospectus is required by the Securities Act (including, without limitation, pursuant to Rule 173(d)) to be delivered in connection with sales of the Securities (but in any event if at any time through and including the Closing Date), the Company receives notice pursuant to Rule 401(g)(2) under the Securities Act from the Commission or otherwise ceases to be eligible to use the automatic shelf registration form, the Company shall promptly advise the Representatives in writing of such notice or ineligibility and, if Securities remain unsold by the Underwriters, the Company will (i) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, (ii) use its reasonable commercial efforts to cause such registration statement or post-effective amendment to be declared effective by the Commission as soon as practicable and (iii) promptly notify the Representatives in writing of such effectiveness. The Issuers shall pay the fees applicable to the Registration Statement in

connection with the offering of the Securities within the time required by Rule 456(b)(1)(i) under the Act (without reliance on the proviso to Rule 456(b)(1)(i) under the Act) and in compliance with Rule 456(b) and Rule 457(r) under the Act.

          (h) Amendments and Supplements to the Prospectus and Other Securities Act Matters. If any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus so that the Prospectus does 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 when the Prospectus is delivered to a purchaser, not misleading, or if in the reasonable opinion of the Representatives or counsel for the Underwriters it is otherwise necessary to amend or supplement the Prospectus to comply with applicable law, including the Securities Act, the Issuers shall (subject to Section 3(b) and 3(c)) promptly prepare, file with the Commission and furnish at its own expense to the Underwriters and to dealers, amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented 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 when the Prospectus is delivered to a purchaser, not misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law, including the Securities Act. Neither the Representatives’ consent to, or delivery of, any such amendment or supplement shall constitute a waiver of any of the Issuers’ obligations under Sections 3(b) or (c).

          (i) Blue Sky Compliance.

          (a) Indemnification of the Underwriters. The Issuers jointly and severally agree to indemnify and hold harmless each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act, other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430B under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any free writing prospectus that the Issuers have used, referred to or filed, or are required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (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; or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Securities or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (i) or (ii) above, provided that the Issuers shall not be liable under this clause (iii) to any Underwriter, to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its bad faith or willful misconduct and to reimburse each Underwriter and each such officer, employee and controlling person for any and all expenses (including the fees and disbursements of counsel chosen by the Representatives) as such expenses are reasonably incurred by such Underwriter or such officer, employee or 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 Issuers by the Representatives expressly for use in the Registration Statement, any prelimi-

nary prospectus, the Time of Sale Prospectus, any such free writing prospectus or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by the Representatives to the Issuers consists of the information described in subsection (b) below. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Issuers may otherwise have.

          (b) Indemnification of the Issuers and their Directors and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuers, each of their directors (including managers, members, partners and others having similar positions, who, in each case in this parenthetical, have liability for the Registration Statement under Section 11 of the Securities Act), each of their officers (including managers, members, partners and others having similar positions, who, in each case in this parenthetical, have liability for the Registration Statement under Section 11 of the Securities Act) who signed the Registration Statement and each person, if any, who controls any Issuer within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which any Issuer, or any such director, officer, manager, member, partner, other person having similar positions 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), 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 Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430B under the Securities Act, or any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Issuers have used, referred to or filed, or are required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (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 required to be stated therein or necessary to make the statements therein (in the case of any preliminary prospectus, the Time of Sale Prospectus, any such free writing prospectus, or the Prospectus, 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 Registration Statement, such amendment thereto, such preliminary prospectus, the Time of Sale Prospectus, such free writing prospectus that the Issuers have used, referred to or filed, or are required to file, pursuant to Rule 433(d) of the Securities Act, the Prospectus (or such amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Issuers by the Representatives expressly for use therein; and to reimburse the Issuers, or any such director, officer, manager, member, partner, other person having similar positions or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by them) as such expenses are reasonably incurred by any Issuer, or any such director, officer, manager, member, partner, other person having similar positions or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Issuers hereby acknowledge that the only information that the Representatives and the Underwriters have furnished to the Issuers expressly for use in the Registration Statement, any amendment thereto, any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Issuers have filed, or are required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (or any amendment or supplement thereto) are the statements set

The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter 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 is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve the indemnifying party from any liability which it may have to any indemnified party for contribution under Section 9 below or otherwise under the indemnity agreement contained in this Section 8, except to the extent such indemnifying party is materially 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 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 (which shall not be unreasonably withheld, delayed or conditioned), the indemnifying party or parties 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 preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the fees and expenses of more than one separate firm of attorneys (together with local counsel), representing the indemnified parties who are parties to such action), which counsel (together with any local counsel) for the indemnified parties shall be selected by the Representatives (in the case of counsel for the indemnified parties referred to in Section 8(a) above) or by the Company (in the case of counsel for the indemnified parties referred to in Section 8(b) above)), (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party authorizes the indemnified party to employ separate counsel at the indemnifying party’s expense, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred.

          (d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent (such consent not to be unreasonably withheld, delayed or conditioned), 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 (to the extent provided in this Section 8) 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 (to the extent provided in this Section 8) 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 (including documentation of such fees and expenses reasonably satisfactory to the indemnifying party) and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request (to the extent required by this Section 8) 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 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 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 Issuers, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Issuers, on the one hand, and the Underwriters, 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 Issuers, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Issuers, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the front cover page of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the Issuers, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuers, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent,

knowledge, access to information and opportunity to correct or prevent such statement or omission.

          The 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 Issuers and the Underwriters 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 Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

          Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public. 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 Underwriters’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their respective names on Schedule A. For purposes of this Section 9, each officer and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Underwriter, and each director (including managers, members, partners and others having similar positions who, in each case in this parenthetical, have liability for the Registration Statement under Section 11 of the Securities Act) of the Issuers, each officer (including managers, members, partners and others having similar positions who, in each case in this parenthetical, have liability for the Registration Statement under Section 11 of the Securities Act) of the Issuers who signed the Registration Statement, and each person, if any, who controls the Issuers with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Issuers.

     Section 10. Default of One or More of the Several Underwriters. If, on the Closing Date, any one or more of the several Underwriters 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 Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, the Representatives may make arrangements satisfactory to the Issuers for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the other Underwriters shall be obligated, severally and not jointly, in the proportions that the principal amount of Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may

be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Issuers for the purchase of such Securities 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 Section 4, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Issuers 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 Registration Statement and the Prospectus or any other documents or arrangements may be effected.

          As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

     Section 11. Termination of this Agreement. Prior to the purchase of the Securities by the Underwriters on 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 by any exchange, or trading in securities generally on any exchange shall have been suspended or limited, the settlement of such trading shall have been materially disrupted or minimum or maximum prices shall have been generally established on any of such stock exchanges by such exchange, the Commission or the FINRA; (ii) a general banking moratorium shall have been declared by any of federal, New York, or Delaware authorities; (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 Representatives is material and adverse and makes it impracticable to market the Securities in the manner and on the terms described in the Time of Sale Prospectus or the Prospectus 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) 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 Representatives may 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 11 shall be without liability on the part of (a) the Issuers to any Underwriter, except that the Issuers shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Sections 4 and 7 hereof, (b) any Underwriter to the Issuers, or (c) of any party hereto to any other party except as aforesaid and except that the provisions of Section 8 and Section 9 shall at all times be effective and shall survive such termination.

     Section 12. No Advisory or Fiduciary Relationship. Each of the Issuers acknowledges and agrees that (a) the purchase and sale of the Securities sold by such party pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, are an arm’s-length commercial transaction between such party, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of such party, or its stockholders, creditors or employees, as applicable, or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of such party with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising any Issuer on other matters) and no Underwriter has any obligation to such party with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Issuers, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and such party has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

     Section 13. Certain Acknowledgments. The Issuers understand that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

     Each Underwriter, severally and not jointly, represents and warrants to and agrees with the Issuers that:

          (a) in relation to each Member State of the European Economic Area (namely, the European Union, Iceland, Norway and Liechtenstein) which has implemented the Prospectus Directive (each, a Relevant Member State), with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the Relevant Implementation Date), it has not made and will not make an offer of notes to the public in that Relevant Member State prior to the publication of a prospectus in relation to the notes which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of notes to the public in that Relevant Member State at any time:

     (iv) in any other circumstances which do not require the publication by the issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of notes to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and the expression “Prospectus Directive” means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

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.
