Ladies and Gentlemen:

U.S. Auto Parts Network, Inc., a Delaware corporation (the “Issuer”) and certain stockholders of the Issuer (the “Selling Stockholders”) propose to sell to the several underwriters (the “Underwriters”) named in Schedule I hereto for whom you are acting as representatives (the “Representatives”) an aggregate of 10,000,000 shares of the Issuer’s Common Stock, $0.001 par value (the “Firm Securities”), of which 8,000,000 shares will be sold by the Issuer and 2,000,000 shares will be sold by the Selling Stockholders. The respective amounts of the Firm Securities to be so purchased by the several Underwriters are set forth opposite their names in Schedule I hereto and the respective amounts to be sold by the Selling Stockholders are set forth opposite their names in Schedule II hereto. The Selling Stockholders also propose to sell at the Underwriters’ option an aggregate of up to 1,500,000 additional shares of the Issuer’s Common Stock (the “Option Securities”) as set forth below.

As the Representatives, you have advised the Issuer and the Selling Stockholders (a) that you are authorized to enter into this Agreement on behalf of the several Underwriters, and (b) that the several Underwriters are willing, acting severally and not jointly, to purchase the numbers of Firm Securities set forth opposite their respective names in Schedule I, plus their pro rata portion of

the Option Securities if you elect to exercise the over-allotment option in whole or in part for the accounts of the several Underwriters. The Firm Securities and the Option Securities (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.”

The Issuer hereby acknowledges that, in connection with the proposed offering of the Shares, it has requested RBC Capital Markets Corporation to administer a directed share program (the “Directed Share Program”) under which up to 500,000 Firm Securities, or 5% of the Firm Securities to be purchased by the Underwriters (the “Reserved Shares”), shall be reserved for sale by RBC Capital Markets Corporation at the initial public offering price to the Issuer’s officers, directors, employees and consultants and other persons having a relationship with the Issuer as designated by the Issuer, (the “Directed Share Participants”) as part of the distribution of the Shares by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the National Association of Securities Dealers, Inc. (“NASD”) and all other applicable laws, rules and regulations. The number of Shares available for sale to the general public will be reduced to the extent that Directed Share Participants purchase Reserved Shares. The Underwriters may offer any Reserved Shares not purchased by Directed Share Participants to the general public on the same basis as the other Shares being issued and sold hereunder. The Issuer has supplied RBC Capital Markets Corporation with names, addresses and telephone numbers of the individuals or other entities which the Issuer has designated to be participants in the Directed Share Program. It is understood that any number of those designated to participate in the Directed Share Program may decline to do so.

The Issuer has prepared a registration statement on Form S-1 (File No. 333-138379) with respect to the Shares pursuant to the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations (the “Rules and Regulations”) of the United States Securities and Exchange Commission (the “Commission”) thereunder. As used in this Agreement, “Effective Time” means the date and the time as of which such registration statement, or the most recent post-effective amendment thereto, if any, was declared effective by the Commission; “Effective Date” means the date of the Effective Time; “Preliminary Prospectus” means each prospectus included in such registration statement, or amendments thereof, before it became effective under the Securities Act and any prospectus filed with the Commission by the Issuer with the consent of the Underwriters pursuant to Rule 424(a) of the Rules and Regulations; “Pricing Prospectus” means the Preliminary Prospectus that was included in the Registration Statement immediately prior to the Applicable Time (as defined below); “Prospectus” means the prospectus in the form first used to confirm sales of Shares; “Registration Statement” means such registration statement, as amended at the Effective Time, including all information deemed to be a part of the registration statement as of the Effective Time pursuant to Rule 430A of the Rules and Regulations; “Free Writing Prospectus” means any “free writing prospectus” as defined in Rule 405 under the Securities Act relating to the Shares; and “Issuer Free Writing Prospectus” means any “issuer free writing prospectus” as defined in Rule 433 under the Securities Act relating to the Shares. If the Issuer has filed an abbreviated registration statement to register additional Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. For the purposes of this Agreement, the “Applicable Time” is : m (Eastern time) on the date of this Agreement.

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

1. REPRESENTATIONS AND WARRANTIES OF THE ISSUER.

The Issuer represents and warrants to each of the Underwriters as follows:

(a) The Registration Statement has been filed with the Commission under the Securities Act and has become effective under the Securities Act. No stop order suspending the effectiveness of such registration statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Issuer, threatened by the Commission. The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus or any Issuer Free Writing Prospectus. Copies of such registration statement and each of the amendments thereto have been delivered by the Issuer to you. The Registration Statement conforms, and any further amendments or supplements to the Registration Statement will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations. The Prospectus and the Pricing Prospectus each conforms and, as amended or supplemented, will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations. As of the Effective Date, the date hereof, the Closing Date (as defined below) and each Option Closing Date (as defined below), if any, the Registration Statement does not and will not, and any further amendments to the Registration Statement will not, when they become effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; as of its date and the date hereof, the Prospectus does not, and as amended or supplemented on the Closing Date and each Option Closing Date, if any, will not, contain an 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 Pricing Prospectus, as supplemented by the Issuer Free Writing Prospectuses and other documents listed in Schedule III(a) hereto, taken together with the final pricing information included on the cover page of the Prospectus (collectively, the “Disclosure Package”), as of the Applicable Time did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Issuer Free Writing Prospectus listed on Schedule III(a) or Schedule III(b) hereto does not conflict with the information contained in the Registration Statement; and each such Issuer Free Writing Prospectus listed on Schedule III(b), as supplemented by and taken together with the Disclosure Package as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties set forth in this sentence do not apply to statements or omissions in the Registration Statement, the Prospectus, the Pricing Prospectus or any Issuer Free Writing Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Issuer by any Underwriter through RBC Capital Markets Corporation expressly for use therein, such information being listed in Section 15 below. The Issuer filed the Registration Statement with the Commission before using

any Issuer Free Writing Prospectus and, to the extent within the Issuer’s control, each Issuer Free Writing Prospectus was preceded or accompanied by the most recent Preliminary Prospectus satisfying the requirements of Section 10 under the Securities Act, which Preliminary Prospectus included an estimated price range.

(b) Each of the statements contained in the Registration Statement, the Prospectus, the Pricing Prospectus or any Issuer Free Writing Prospectus that constitutes “forward looking” information within the coverage of Rule 175(b) of the Rules and Regulations, including (but not limited to) any of the Issuer’s expectations, plans, intentions, projections, results of operations or statements with respect to future available cash or future cash distributions of the Issuer or the anticipated ratio of taxable income to distributions, was made or will be made with a reasonable basis and in good faith. Notwithstanding the foregoing, this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with written information concerning the Underwriters furnished to the Issuer by or on behalf of any Underwriter specifically for inclusion in the Registration Statement, the Pricing Prospectus or the Prospectus, such information being listed in Section 15 below.

(c) This Agreement has been duly authorized, executed and delivered by the Issuer, and constitutes a valid, legal, and binding obligation of the Issuer, enforceable in accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity. The Issuer has full power and authority to enter into this Agreement and to authorize, issue and sell the Shares as contemplated by this Agreement.

(d) The Issuer has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own or lease its properties and conduct its business as described in the Prospectus and the Disclosure Package. Each of the subsidiaries of the Issuer, as listed in Exhibit A attached hereto (collectively, the “Subsidiaries”), has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, with corporate power and authority to own or lease its properties and conduct its business as described in the Prospectus and the Disclosure Package. The Subsidiaries are the only material subsidiaries, direct or indirect, of the Issuer. The Issuer and each of the Subsidiaries are duly qualified to transact business and are in good standing in all jurisdictions in which the conduct of their business requires such qualification, except where the failure to be so qualified or to be in good standing would not have a material adverse effect on the condition (financial or otherwise), properties, assets, liabilities, operations or business of the Issuer and its Subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business (a “Material Adverse Effect”). Except as indicated on Exhibit A, all of the outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are wholly owned by the Issuer or another Subsidiary free and clear of all liens, encumbrances and equities and claims; and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into shares of capital stock or ownership interests in the Subsidiaries are outstanding.

(e) The outstanding shares of Common Stock of the Issuer, including all shares to be sold by the Selling Stockholders, have been duly authorized and validly issued and are fully paid and non-assessable; the portion of the Shares to be issued and sold by the Issuer have been duly authorized and when issued and paid for as contemplated herein will be validly issued, fully paid and non-assessable; and no preemptive rights of stockholders exist with respect to any of the Shares or the issue and sale thereof. Neither the filing of the Registration Statement nor the offering or sale of the Shares as contemplated by this Agreement gives rise to any rights, other than those which have been waived or satisfied, for or relating to the registration of any shares of Common Stock in connection with the offering or sale of the Shares.

(f) The information set forth under the caption “Capitalization” in the Prospectus and the Disclosure Package is true and correct. All of the Shares conform to the description thereof contained in the Prospectus and the Disclosure Package. The form of certificates for the Shares conforms to the corporate law of the State of Delaware. Immediately after the closing of the issuance and sale of the Shares to the Underwriters, no shares of Preferred Stock of the Issuer shall be issued and outstanding, and no holder of any shares of capital stock, securities convertible into or exchangeable or exercisable for capital stock or options, warrants or other rights to purchase capital stock or any other securities of the Issuer shall have any existing or future right to acquire any shares of Preferred Stock of the Issuer.

(g) The consolidated financial statements of the Issuer and the Subsidiaries, together with related notes and schedules as set forth in the Registration Statement, the Prospectus and the Disclosure Package, present fairly the financial position and the results of operations and cash flows of the Issuer and the consolidated Subsidiaries, at the indicated dates and for the indicated periods. Such financial statements and related schedules have been prepared in accordance with U.S. generally accepted principles of accounting (“GAAP”), consistently applied throughout the periods involved, except as disclosed therein, and all adjustments necessary for a fair presentation of results for such periods have been made; provided, however, that financial statements that are unaudited are subject to normal year end adjustments and do not contain certain footnotes required by GAAP. The summary financial and statistical data included in the Registration Statement, the Prospectus and the Disclosure Package presents fairly the information shown therein and such data has been compiled on a basis consistent with the financial statements presented therein and the books and records of the Issuer. The pro forma financial statements and other pro forma financial information included in the Registration Statement, Prospectus and the Disclosure Package present fairly the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements, have been properly compiled on the pro forma bases described therein, and, in the opinion of the Issuer, the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein. The statistical, industry related and market related data included in the Registration Statement, the Prospectus and the Disclosure Package are based on or derived from sources which the Issuer reasonably and in good faith believes are reliable and accurate.

(h) The Issuer maintains a system of internal accounting controls sufficient to provide reasonable assurances 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 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.

(i) To the Issuer’s knowledge, Ernst & Young LLP, Stonefield Xxxxxxxxx, Inc. and X.X. Xxxx LLP, each of which have certified certain financial statements of the Issuer (or, in the case of X.X. Xxxx LLP, the predecessors of certain of the Issuer’s subsidiaries) and have delivered their opinions with respect to the audited financial statements and schedules included in the Registration Statement and the Prospectus, are (or were) independent registered public accounting firms with respect to the Issuer (or predecessors of certain of the Issuers’ subsidiaries) within the meaning of the Securities Act and the Rules and Regulations.

(j) There is no action, suit, claim or proceeding pending or, to the knowledge of the Issuer, threatened against the Issuer or any of the Subsidiaries before any court or administrative agency or otherwise: (1) that are required to be described in the Registration Statement, the Prospectus or the Disclosure Package and are not so described; or (2) which, if determined adversely to the Issuer or any of its Subsidiaries, would have a Material Adverse Effect or prevent the consummation of the transactions contemplated hereby, except as set forth in the Registration Statement, the Prospectus and the Disclosure Package.

(k) No labor problem or dispute with the employees of the Issuer or the Subsidiaries exists or, to the Issuer’s knowledge, is threatened, and the Issuer is not aware of any existing labor disturbance by the employees of any of its or its Subsidiaries’ principal suppliers, contractors or customers, except for such problems, disputes or disturbances that are not reasonably expected to have a Material Adverse Effect.

(l) The Issuer and the Subsidiaries have good and marketable title to all of the properties and assets reflected in the financial statements (or as described in the Prospectus and the Disclosure Package) hereinabove described, subject to no lien, mortgage, pledge, charge or encumbrance of any kind except those reflected in such financial statements (or as described in the Prospectus and the Disclosure Package) or which are not material in amount and except where the failure to have such title would not have a Material Adverse Effect. The Issuer and the Subsidiaries occupy their leased properties under valid and binding leases conforming in all material respects to the description thereof set forth in the Prospectus and the Disclosure Package.

(m) The Issuer and the Subsidiaries have filed all Federal, State, local and foreign tax returns which have been required to be filed and have paid all taxes indicated by said returns and all assessments received by them or any of them to the extent that such taxes have become due and are not being contested in good faith and for which an adequate reserve for accrual has been established in accordance with GAAP. All tax liabilities have been adequately provided

for in the financial statements of the Issuer to the extent required by GAAP, and the Issuer does not know of any actual or proposed additional material tax assessments that are required by GAAP to be provided for in such financial statements. There are no transfer taxes or other similar fees or charges under Federal law or the laws of any state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Issuer or sale by the Issuer of the Shares.

The Issuer and the Subsidiaries have no material contingent obligations that are not disclosed in the Issuer’s financial statements or otherwise in the Registration Statement and the Prospectus.

(o) Neither the Issuer nor any of the Subsidiaries is or with the giving of notice or lapse of time or both, will be, in violation of or in default under: (i) its Certificate of Incorporation (“Charter”) or By-Laws; or (ii) any agreement, lease, contract, indenture or other instrument or obligation to which it is a party or by which it, or any of its properties, is bound and which violation or default has had or is reasonably likely to have a Material Adverse Effect. The execution and delivery of this Agreement and the consummation of the transactions herein contemplated and the fulfillment of the terms hereof will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under: (i) the Charter or By-Laws of the Issuer; or (ii) any contract, indenture, mortgage, deed of trust or other agreement or instrument to which the Issuer or any of the Subsidiaries is a party, or any order, rule or regulation applicable to the Issuer or any of the Subsidiaries of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction, except, in the case of this clause (ii), for such conflicts, breaches or defaults as would not be reasonably expected to have a Material Adverse Effect.

(p) Each approval, consent, order, authorization, designation, declaration or filing by or with any regulatory, administrative or other governmental body necessary in connection with the execution and delivery by the Issuer of this Agreement and the consummation of the transactions herein contemplated (except such additional steps as may be required by the Commission, the NASD or such additional steps as may be necessary to qualify the Shares for public offering by the Underwriters under state securities or Blue Sky laws or foreign laws) has been obtained or made and is in full force and effect.

There is no claim, proceeding or controversy, pending or, to the

knowledge of the Issuer or any of the Subsidiaries, threatened, involving the status of or sanctions under any of the Permits. The Issuer and each of the Subsidiaries has fulfilled and performed all of its material obligations with respect to the Permits, and to the Issuer’s knowledge, no event has occurred which allows, or after notice or lapse of time would allow, the revocation, termination, modification or other impairment of the rights of the Issuer or any of the Subsidiaries under such Permit.

(r) To the Issuer’s knowledge, there are no affiliations or associations between any member of the NASD and any of the Issuer’s officers, directors or 5% or greater security holders, except as set forth in the Registration Statement.

(s) Neither the Issuer, nor to the Issuer’s knowledge, any of its affiliates, has taken, directly or indirectly, any action designed to cause or result in, or which constitutes, the stabilization or manipulation of the price of the shares of Common Stock to facilitate the sale or resale of the Shares. The Issuer acknowledges that the Underwriters may engage in passive market making transactions in the Shares on The NASDAQ Global Market in accordance with Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

(t) Neither the Issuer nor any of the Subsidiaries is nor, upon the application of the proceeds from the sales of the Shares will be, an “investment company” within the meaning of such term under the Investment Issuer Act of 1940, and the rules and regulations of the Commission thereunder (collectively, the “1940 Act”).

(u) The Issuer and each of the Subsidiaries carry, or are covered by, insurance in such amounts and covering such risks as is adequate for the conduct of their respective businesses and the value of their respective properties and as is customary for companies engaged in similar industries. All policies of insurance insuring the Issuer or any Subsidiary or any of their respective businesses, assets, employees, officers and directors are in full force and effect, and the Issuer and the Subsidiaries are in compliance with the terms of such policies in all material respects. There are no claims by the Issuer or any Subsidiary under any such policy or instrument as to which an insurance company is denying liability or defending under a reservation of rights clause.

(v) The Issuer is in compliance in all material respects with all presently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”); no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Issuer would have any liability; the Issuer has not incurred and does not expect to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Issuer would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and, to the Issuer’s knowledge, nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

(w) Other than as contemplated by this Agreement, the Issuer has not incurred any liability for any finder’s or broker’s fee, or agent’s commission in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby.

(x) Other than the Subsidiaries, the Issuer does not own, directly or indirectly, any shares of capital stock and does not have any other equity or ownership or proprietary interest in any corporation, partnership, association, trust, limited liability company, joint venture or other entity.

(y) There are no statutes, regulations, contracts or other documents (including, without limitation, any voting agreement) that are required to be described in the Registration Statement, the Prospectus or the Disclosure Package or to be filed as exhibits to the Registration Statement that are not described or filed as required. Neither the Issuer nor any of the Subsidiaries has sent or received any notice indicating the termination of or intention to terminate any of the contracts or agreements referred to or described in the Registration Statement, Prospectus or the Disclosure Package, or filed as an exhibit to the Registration Statement, and no such termination has been threatened by the Issuer, any Subsidiary or any other party to any such contract or agreement.

To the Issuer’s knowledge, neither the Issuer nor the Subsidiaries own or operate any real property contaminated with any substance that is subject to any Environmental Laws, is liable for any off-site disposal or contamination pursuant to any Environmental Laws, or is subject to any claim relating to any Environmental Laws, which violation, contamination, liability or claim would individually or in the aggregate have a Material Adverse Effect; and the Issuer is not aware of any pending investigation which might lead to such a claim.

(aa) No payments or inducements have been made or given, directly or indirectly, to any federal or local official or candidate for, any federal or state office in the United States or foreign offices by the Issuer or any Subsidiary, or to the Issuer’s knowledge, by any of their officers, directors, employees, agents or any other person in connection with any opportunity, contract, permit, certificate, consent, order, approval, waiver or other authorization relating to the business of the Issuer or any Subsidiary, except for such payments or inducements as were lawful under applicable laws, rules and regulations. Neither the Issuer nor any Subsidiary, nor, to the knowledge of the Issuer, any director, officer, agent, employee or other person associated with or acting on behalf of the Issuer or any Subsidiary, (i) has used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense

Except as specifically described in the Prospectus and the Disclosure Package: (i) no third parties have obtained rights from the Issuer or any of the Subsidiaries to any Intellectual Property owned, licensed, or otherwise controlled by the Issuer or any of the Subsidiaries (collectively, “Issuer Intellectual Property”), other than licenses granted in the ordinary course and those that would not have a Material Adverse Effect; (ii) to the Issuer’s knowledge, there is no infringement or misappropriation by others of any such Issuer Intellectual Property, except where such infringement or misappropriation, individually or in the aggregate, would not have a Material Adverse Effect; (iii) there is no pending or, to the Issuer’s knowledge, threatened action, suit, proceeding or claim by others challenging the Issuer’s or any of the Subsidiaries’ rights in or to any Issuer Intellectual Property; (iv) there is no pending or, to the Issuer’s knowledge, threatened action, suit, proceeding or claim by others against the Issuer or any of the Subsidiaries challenging the validity, enforceability, or scope of any such Issuer Intellectual Property; (v) to the Issuer’s knowledge, there is no pending or threatened action, suit, proceeding or claim by others against any third party challenging the validity, enforceability, or scope of any such Issuer Intellectual Property; (vi) there is no prior art or public or commercial activity of which the Issuer is aware that may render any patent held by the Issuer or any of the Subsidiaries invalid or any patent application held by the Issuer or any of the Subsidiaries unpatentable which has not been disclosed to the U.S. Patent and Trademark Office in compliance with all applicable laws; (vii) there is no prior, pending, or, to the Issuer’s knowledge, threatened action, suit, proceeding, or claim by others against the Issuer or any of the Subsidiaries that the Issuer or any of the Subsidiaries, any services performed or technology employed by the Issuer or any of the Subsidiaries, any products promoted, offered, distributed, or sold by the Issuer or any of the Subsidiaries, or any products, services, or technology to be sold, performed, or employed as described in the Prospectus (if such products, services, or technology actually were sold, performed, or employed as so described), infringes, misappropriates, or otherwise violates any Intellectual Property of others, and the Issuer is unaware of any facts which would form a reasonable basis for any such claim; (viii) to the Issuer’s knowledge, there is no Intellectual Property owned or controlled by a third party that: covers or reasonably may be deemed to cover any Issuer Intellectual Property; is necessary for the conduct of the Issuer’s or any of the Subsidiaries’ businesses as currently or, as described in the Prospectus, contemplated to be conducted; or interferes or reasonably could interfere with such businesses or with any Issuer Intellectual Property in a manner that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect; and (ix) either the Issuer or one of the Subsidiaries of the Issuer exclusively holds the first

rights to enforce, protect, and defend all patents, copyrights, trademarks, service marks, trade names, domain names, and applications for any of the foregoing included in the Issuer Intellectual Property and to seek all legal and equitable remedies against others by reason of past, present, and future infringement or misappropriation of such Issuer Intellectual Property, except with respect to any Intellectual Property that the Issuer has licensed from third parties where such third party may hold these rights or where the failure to have such rights would not have a Material Adverse Effect. Except as disclosed in the Prospectus, to the Issuer’s knowledge, none of the technology employed, or products promoted, offered, distributed, or sold, by the Issuer or any of the Subsidiaries has been obtained or, to the Issuer’s knowledge, is being used, promoted, offered, distributed, or sold by the Issuer or any of the Subsidiaries in violation of the Intellectual Property or other rights of any third party. Each current employee and independent contractor who is an executive officer of the Issuer or a Subsidiary or performs services of an inventive or creative nature in connection with the development of Intellectual Property of the Issuer or a Subsidiary, has signed and delivered one or more written contracts with the Issuer or such Subsidiary pursuant to which such employee or independent contractor assigns to the Issuer or such Subsidiary all of his, her, or its rights in and to any inventions, discoveries, improvements, works of authorship, know-how, or information made, conceived, reduced to practice, authored, or discovered in the course of employment by, or performance of services for, the Issuer or such Subsidiary, and to any and all Intellectual Property relating thereto. The Issuer and the Subsidiaries took all reasonable measures to obtain such written contracts from their respective former employees, and from their respective former independent contractors who performed services of an inventive or creative nature, except where the failure to do so would not have, individually or in the aggregate, a Material Adverse Effect. The Issuer previously has provided to the Underwriters true and complete lists all of the issued patents, registered copyrights, registered trademarks, registered domain names, and registered databases in which the Issuer or any of the Subsidiaries has rights.

(cc) The conduct of business by the Issuer and each of the Subsidiaries complies, and at all times has complied, in all material respects with federal, state, local and foreign laws, statutes, ordinances, rules, regulations, decrees, orders, Permits and other similar items (“Laws”) applicable to its business, including, without limitation, (i) the Xxxxxxx Antitrust Act and similar federal, state, local and foreign Laws applicable to anti-competitive practices and consumer protection; and (ii) licensing and certification Laws covering any aspect of the business of the Issuer or any of the Subsidiaries. Neither the Issuer nor any of the Subsidiaries has received any notification asserting, or has knowledge of, any present or past failure to comply with or violation of any such Laws, except for violations that would not reasonably be expected to have a Material Adverse Effect.

(dd) Any certificate signed by any officer of the Issuer and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Shares contemplated hereby shall be deemed a representation and warranty by the Issuer to each Underwriter and shall be deemed to be a part of this Section 1 and incorporated herein by this reference.

(c) Such Selling Stockholder has not taken and will not take, directly or indirectly, any action designed to, or which has constituted, or which might reasonably be expected to cause or result in the stabilization or manipulation of the price of the Common Stock of the Issuer and, other than as permitted by the Securities Act, the Selling Stockholder will not distribute any prospectus or other offering material in connection with the offering of the Shares.

(d) Without having undertaken to determine independently the accuracy or completeness of either the representations and warranties of the Issuer contained herein or the information contained in the Registration Statement, such Selling Stockholder has no reason to believe that the representations and warranties of the Issuer contained in Section 1 are not true and

correct, has reviewed and is familiar with the Registration Statement, has no knowledge of any material fact, condition or information not disclosed in the Registration Statement which has adversely affected or may adversely affect the business of the Issuer or any of the Subsidiaries and has no reason to believe that the Registration Statement or the Prospectus contains any untrue statement of a material fact, or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading; and the sale of the Firm Shares and the Option Shares by such Selling Stockholder pursuant hereto is not prompted by any information concerning the Issuer or any of the Subsidiaries which is not set forth in the Registration Statement. The information pertaining to such Selling Stockholder under the caption “Principal and Selling Stockholders” in the Prospectus and any information pertaining to such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder for use in the Registration Statement is complete and accurate in all material respects.

(e) Except as disclosed in the Prospectus, there are no contracts, agreements or understandings between such Selling Stockholder and any person that would give rise to a valid claim against such Selling Stockholder or any Underwriter for a brokerage commission, finder’s fee or other like payment in connection with this offering.

3. PURCHASE, SALE AND DELIVERY OF THE FIRM SECURITIES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Issuer and each of the Selling Stockholders agree to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $ per share, the number of Firm Securities set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 11 hereof. The number of Firm Securities to be purchased by each Underwriter from each seller shall be as nearly as practicable in the same proportion to the total number of Firm Securities being sold by each seller as the number of Firm Securities being purchased by each Underwriter bears to the total number of Firm Securities to be sold hereunder. The obligations of the Issuer and of each of the Selling Stockholders shall be several and not joint.

(b) Certificates in negotiable form for the total number of the Shares to be sold hereunder by the Selling Stockholders have been placed in custody with U.S. Stock Transfer Corporation as custodian (the “Custodian”) pursuant to the Custodian Agreement executed by each Selling Stockholder for delivery of all Firm Securities and any Option Securities to be sold hereunder by the Selling Stockholders. Each of the Selling Stockholders specifically agrees that the Firm Securities and any Option Securities represented by the certificates held in custody for the Selling Stockholders under the Custodian Agreement are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Stockholders for such custody are to that extent irrevocable, and that the obligations of the Selling Stockholders hereunder shall not be terminable by any act or deed of the Selling Stockholders (or by any other person, firm or corporation including the Issuer, the Custodian or the Underwriters) or by operation of law (including the death of an individual Selling Stockholder or the dissolution of a corporate Selling Stockholder) or by the occurrence of any other event or events, except as set forth in the Custodian Agreement. If any such event should occur prior to the delivery to the Underwriters of the Firm

Securities or the Option Securities hereunder, certificates for the Firm Securities or the Option Securities, as the case may be, shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement as if such event has not occurred. The Custodian is authorized to receive and acknowledge receipt of the proceeds of sale of the Shares held by it against delivery of such Shares.

(c) Payment for the Firm Securities to be sold hereunder is to be made by wire transfer of Federal (same day) funds to an account designated by the Issuer for the shares to be sold by it and to an account designated by the Custodian for the shares to be sold by the Selling Stockholders, in each case against delivery of certificates therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made through the facilities of the Depository Trust Issuer, New York, New York at 10:00 a.m., New York time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Issuer shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and are not permitted by law or executive order to be closed.

(d) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Selling Stockholders hereby grant an option to the several Underwriters to purchase the Option Securities at the price per share as set forth in the first paragraph of this Section. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, by you, as the Representatives of the several Underwriters, to the Issuer, the Attorney-in-Fact and the Custodian setting forth the number of Option Securities as to which the several Underwriters are exercising the option, the names and denominations in which the Option Securities are to be registered and the time and date at which such certificates are to be delivered. If the option granted hereby is exercised in part, the respective number of Option Securities to be sold by each of the Selling Stockholders shall be in the same proportion to the total number of Option Securities being sold as the number of Firm Securities being sold by each of the Selling Stockholders bears to the total number of Firm Securities, adjusted by you in such manner as to avoid fractional shares. The time and date at which certificates for Option Securities are to be delivered shall be determined by the Representatives but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Securities to be purchased by each Underwriter shall be in the same proportion to the total number of Option Securities being purchased as the number of Firm Securities being purchased by such Underwriter bears to the total number of Firm Securities, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Securities granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Securities by the Underwriters. You, as the Representatives of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Issuer and the Attorney-in-Fact. To the extent, if any, that the option is exercised, payment for the Option Securities shall be made on

Each Underwriter represents and agrees that it has not made and, without the prior consent of the Issuer, RBC Capital Markets Corporation and Xxxxxx Xxxxxx Partners LLC, will not make, any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus.

The Issuer will use its best efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.

(e) The Issuer will cooperate with the Representatives in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representatives may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Issuer shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent.

(h) The Issuer will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earning statement shall satisfy the requirements of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations and will advise you in writing when such statement has been so made available.

The foregoing will not apply to (A) equity grants made to employees, consultants, officers or directors of the Issuer pursuant to employee benefit plans described in the Prospectus and the Disclosure Package; (B) issuances pursuant to the exercise or conversion of exercisable or convertible

securities outstanding on the date of this Agreement; or (C) up to 2,983,293 shares of Common Stock (as adjusted for stock splits, stock dividends, recapitalizations and the like) issued in connection with a strategic partnership, joint venture, lending or similar arrangement, or in connection with the acquisition (by merger or otherwise) or license by the Issuer of any businesses, services or technologies; provided, however that the recipients of any shares issued under this clause (C) are restricted from selling, transferring or requiring registration of such shares during the Lock-Up Period; and provided, further that such shares are not issued until at least 30 days from the date of this Agreement.

(n) The Issuer shall not invest, or otherwise use the proceeds received by the Issuer from its sale of the Shares in such a manner as would require the Issuer or any of the Subsidiaries to register as an investment company under the 0000 Xxx.

10. INDEMNIFICATION.

(a) The Issuer agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; or (iii) any alleged act or failure to act by RBC Capital Markets Corporation in connection with, or relating in any manner to, the Directed Share Program (provided, however, that the Issuer shall not be liable under this clause (iii) for any loss, claim, damage, liability or action that is finally judicially determined to have resulted from the gross negligence or willful misconduct of RBC Capital Markets Corporation in conducting the Directed Share Program); and will reimburse any legal or other expenses reasonably incurred by the Underwriter and such controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding (whether or not such Underwriter or controlling person is a party thereto); provided, however, that the Issuer will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, Pricing Prospectus, the Prospectus, or such amendment or supplement, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act in reliance upon and in conformity with written information furnished to the Issuer by or through the Representatives specifically for use in the preparation thereof, such information being listed in Section 15 below.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless the Issuer, each of its directors, each of its officers who have signed the Registration Statement, the Selling Stockholders and each person, if any, who controls the Issuer or the Selling Stockholders within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Issuer or any such director, officer, Selling Stockholder or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages

or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act; or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Issuer or any such director, officer, Selling Stockholder or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act in reliance upon and in conformity with written information furnished to the Issuer by or through the Representatives specifically for use in the preparation thereof, such information being listed in Section 15 below.

(c) Each Selling Stockholder agrees, severally and not jointly, to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, but in each instance only with reference to information relating to such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder expressly for use in the Registration Statement, the Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. Notwithstanding any other provision of this Agreement, the liability of each of Selling Stockholder under and in connection with this Agreement, the transactions contemplated hereby, and the Custody Agreement shall be limited to an amount equal to the proceeds received by such Selling Shareholder from the Underwriters in the offering. For purposes of this Section 10(c), the parties hereto acknowledge and agree that the information regarding the name of, and the number of shares of Common Stock beneficially owned by, such Selling Stockholder in the section captioned “Principal [and Selling] Stockholders” in the Registration Statement is the only information relating to such Selling Stockholder furnished in writing by such Selling Stockholder for use in the Registration Statement, the Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 10(a), (b) or (c) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 10(a), (b) or (c). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment to the extent such party is entitled to indemnification pursuant to Section 10(a), (b) or (c) above. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(e) If the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under Section 10(a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the

Issuer, the Selling Stockholders and the Underwriters from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer, the Selling Stockholders and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Issuer, the Selling Stockholders and the Underwriters shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuer or each Selling Stockholder, as the case may be, bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer, the Selling Stockholder or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Issuer, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Subsection. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Subsection shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Subsection, (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, (ii) 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 and (iii) no Selling Stockholder shall be required to contribute any amount in excess of the proceeds received by such Selling Stockholder from the Underwriters in the offering. The Underwriters’ obligations in this Subsection to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any supplement or amendment thereto, or any Issuer Free Writing Prospectus, each party against whom contribution may be sought under this Section hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon him or it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join him or it as an additional defendant in any such proceeding in which such other contributing party is a party.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section and the representations and warranties of the Issuer set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Issuer, its directors or officers or any persons controlling the Issuer, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or to the Issuer, its directors or officers, or any person controlling the Issuer, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section.

11. DEFAULT BY UNDERWRITERS.

If on the Closing Date or the Option Closing Date, if any, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Issuer or a Selling Stockholder), you, as the Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Issuer and the Selling Stockholders such amounts as may be agreed upon and upon the terms set forth herein, the Firm Securities or Option Securities, as the case may be, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other Underwriters, or any others, to purchase the Firm Securities or Option Securities, as the case may be, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Firm Securities or Option Securities, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Securities or Option Securities, as the case may be, which they are obligated to purchase hereunder, to purchase the Firm Securities or Option Securities, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of shares of Firm Securities or Option Securities, as the case may be, with respect to which such default shall occur exceeds 10% of the Firm Securities or Option Securities, as the case may be, covered hereby, the Issuer and the Selling Stockholders or you as the Representatives of the Underwriters will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Issuer or of the Selling Stockholders except to the extent otherwise provided in Section 13 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section, the Closing Date or Option Closing Date, if any, may be postponed for such period, not exceeding seven days, as you, as Representatives, may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(b) as provided in Sections 8 and 11 of this Agreement.

14. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Issuer, the Selling Stockholders and Underwriters and their respective successors, executors, administrators, heirs and

assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase.

15. INFORMATION PROVIDED BY UNDERWRITERS.

The Issuer, the Selling Stockholders and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Issuer for inclusion in any Preliminary Prospectus, Prospectus, Issuer Free Writing Prospectus or the Registration Statement consists of the information set forth in the table under the first paragraph under the caption “Underwriting” in the Prospectus, the information set forth in the first and second paragraphs and the table under the sub-caption “Underwriting — Commissions and Expenses”, the information set forth in the first paragraph under the sub-caption “Underwriting — Offering Price Determination” and the information set forth in second through fifth paragraphs under the sub-caption “Underwriting — Stabilization, Short Positions and Penalty Bids”.

16. RESEARCH INDEPENDENCE

In addition, the Issuer acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Issuer and/or the offering that differ from the views of its investment bankers. The Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuer by such Underwriters’ investment banking divisions. The Issuer acknowledges 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 position in debt or equity securities of the companies which may be the subject to the transactions contemplated by this Agreement.

17. NO FIDUCIARY DUTY.

Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters, the Issuer and each of the Selling Stockholders acknowledge and agree that:

(a) nothing herein shall create a fiduciary or agency relationship between the Issuer and the Selling Stockholders, on the one hand, and the Underwriters on the other;

(b) the Underwriters are not acting as advisors, expert or otherwise, to the Issuer or the Selling Stockholders in connection with this offering, sale of the Shares or any other

services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares;

(c) the relationship between and the Selling Stockholders, on the one hand, and the Underwriters on the other, is entirely and solely commercial, based on arms-length negotiations;

(d) any duties and obligations that the Underwriters may have to the Issuer and the Selling Stockholders shall be limited to those duties and obligations specifically stated herein; and

(e) notwithstanding anything in this Agreement to the contrary, the Issuer and each of the Selling Stockholders acknowledge that the Underwriters may have financial interests in the success of the Offering that are not limited to the difference between the price to the public and the purchase price paid to the Issuer or the Selling Stockholders by the Underwriters for the shares, and the Underwriters have no obligation to disclose, or account to the Issuer or the Selling Stockholders for, any of such additional financial interests.

The Issuer and each of the Selling Stockholders hereby waive and release, to the fullest extent permitted by law, any claims that the Issuer or such Selling Stockholder may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty.

18. FAILURE OF THE SELLING STOCKHOLDERS TO SELL AND DELIVER SHARES.

If the Selling Stockholders shall fail to sell and deliver to the Underwriters their portion of the Firm Securities or the Option Securities to be sold and delivered by the Selling Stockholders at the Closing Date or any Option Closing Date pursuant to this Agreement, then the Underwriters may at their option, by written notice from the Representatives to the Issuer and the Selling Stockholders, either (i) terminate this Agreement without any liability on the part of any Underwriter or, except as provided in Sections 7 and 10 hereof, the Issuer or the Selling Stockholders or (ii) require the Issuer to deliver for sale any Shares which the Selling Stockholders fail to sell or deliver. If the Selling Stockholders shall fail to sell and deliver to the Underwriters the Shares to be sold and delivered by the Selling Stockholders pursuant to this Agreement at any Option Closing Date, then the Underwriters shall have the right, by written notice from the Representatives to the Issuer and the Selling Stockholders, to postpone the applicable Option 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.

19. MISCELLANEOUS.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by

or on behalf of any Underwriter or controlling person thereof, or by or on behalf of the Issuer or its directors or officers and (c) delivery of and payment for the Shares under this Agreement.

This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

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 only be amended or modified in writing, signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.
