Ladies and Gentlemen:

Introductory. TTM Technologies, Inc., a Washington corporation (the "Company"), proposes to issue and sell to the several underwriters named in Schedule A (the "Underwriters") an aggregate of 2,250,000 shares of its Common Stock, no par value (the "Common Shares"); and [Circuit Holdings LLC,] the ▇▇▇▇▇▇ Capital Partners entities named in Schedule B and the ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ & Partners Fund, L.P., each stockholders of the Company (collectively, the "Principal Selling Stockholders"), and the other stockholders of the Company named in Schedule B (the "Other Selling Stockholders" and, together with the Principal Selling Stockholders, being referred to herein, collectively, as the "Selling Stockholders") severally propose to sell to the Underwriters an aggregate of 4,750,000 Common Shares. The 2,250,000 Common Shares to be sold by the Company and the 4,750,000 Common Shares to be sold by the Selling Stockholders are collectively called the "Firm Shares." In addition, the Selling Stockholders have severally granted to the Underwriters an option to purchase up to an additional 1,050,000 Common Shares, each Selling Stockholder selling up to the amount set forth opposite such Selling Stockholder's name in Schedule B, all as provided in Section 2. The additional [ ] Common Shares to be sold by the Selling Stockholders pursuant to such option are collectively called the "Option Shares." The Firm Shares and, if and to the extent such option is exercised, the Option Shares are collectively called the "Shares." ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Inc. ("▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇") and [Co-Managers] have agreed to act as representatives of the several Underwriters (in such capacity, the "Representatives") in connection with the offering and sale of the Shares.

The Company has prepared and filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (File No. 333-[ ]), which contains a form of prospectus, subject to completion, to be used in connection with the public offering and sale of the Shares. Each such prospectus, subject to completion, used in connection with such public offering is called a "preliminary prospectus." Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it was declared effective by the Commission 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 430A under the Securities Act, is called the "Registration Statement." Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act is called the "Rule 462(b) Registration Statement," and from and after the date and time of filing of the Rule 462(b) Registration Statement the term "Registration Statement" shall include the Rule 462(b) Registration Statement. Such prospectus, in the form first used by the Underwriters to confirm sales of the Shares, including all documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a part thereof at such time pursuant to Rule 430A or 434 under the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations

promulgated thereunder (collectively, the "Exchange Act"), is called the "Prospectus," which term shall be deemed to include the "electronic Prospectus" provided by the Company for use in connection with the offering of the Shares as contemplated by Section 3(e) of this Agreement. All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, a preliminary prospectus, 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 or other information which is "contained," "included" or "stated" in the Registration Statement 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 is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement or in the Prospectus 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 or the Prospectus, as the case may be.

The Company and each of the Selling Stockholders hereby confirm their respective agreements with the Underwriters as follows:

Section 1. Representations and Warranties of the Company and the Selling Stockholders.

A. Representations and Warranties of the Company and the Principal Selling Stockholders. The Company and the Principal Selling Stockholders hereby jointly and severally represent, warrant and covenant to each Underwriter as follows:

(a) Compliance with Registration Requirements. The Registration Statement and any Rule 462(b) Registration Statement have been declared effective by the Commission under the Securities Act. The Company has complied to the Commission's satisfaction with all requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best 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 to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Shares.

(b) No Material Misstatements or Omissions in Registration Statement or Prospectus. Each of the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendment thereto, at the time it became effective and at all subsequent times, complied and will comply in all material respects with the Securities Act and 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. Each preliminary prospectus, as of its date, and the Prospectus, as amended or supplemented, as of its date and at all subsequent times through the 30^th day after the date hereof, 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 two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement, any Rule 462(b) Registration Statement, or any post-effective amendment thereto, or the 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. There are no agreements or contracts or other documents required to be described in the Prospectus or to be filed as exhibits to the Registration Statement which have not been described or filed as required.

(c) Offering Materials Furnished to Underwriters. The Company has delivered to each of the Representatives one complete conformed copy of the Registration Statement and of each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement (without exhibits) and preliminary prospectuses and the Prospectus, as amended or supplemented, in such quantities and at such places as the Representatives have reasonably requested for each of the Underwriters.

(d) Distribution of Offering Material by the Company. The Company has not distributed and will not distribute, prior to the later of the Second Closing Date (as defined below) and the completion of the Underwriters' distribution of the Shares, any offering material in connection with the offering and sale of the Shares other than a preliminary prospectus, the Prospectus or the Registration Statement.

(e) The Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by, and is a valid and binding agreement of, the Company, enforceable in accordance with its terms, except as rights to indemnification and contribution hereunder may be limited by applicable law or applicable public policy and except as the enforcement hereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

(f) Authorization of the Shares to be Sold by the Company. The Shares to be purchased by the Underwriters from the Company have been duly authorized for issuance and sale pursuant to this Agreement and, when issued and delivered by the Company pursuant to this Agreement, will be validly issued, fully paid and nonassessable.

(g) No Applicable Registration or other Similar Rights. There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, other than the Selling Stockholders with respect to their Shares included in the Registration Statement and except for such rights as have been duly waived in writing and for which the written waiver letters have been delivered to the Underwriters.

(h) No Material Adverse Change. Subsequent to the respective dates as of which information is given in the Prospectus: (i) there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business or operations, whether or not arising from transactions in the ordinary course of business, of the Company and its subsidiary, considered as one entity (any such change or effect, where the context so requires, is called a "Material Adverse Change" or a "Material Adverse Effect"); (ii) the Company and its subsidiary, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the ordinary course of business nor entered into any material transaction or agreement not in the ordinary course of business; and (iii) there has been no dividend or distribution of any kind declared, paid or made by the Company or, except for dividends paid to the Company, its subsidiary on any class of capital stock or repurchase or redemption by the Company or its subsidiary of any class of capital stock.

(j) Preparation of the Financial Statements. The financial statements filed with the Commission as a part of the Registration Statement and included in the Prospectus present fairly the consolidated financial position of the Company and its subsidiary 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 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. The financial data set forth in the Prospectus under the captions "Prospectus Summary—Summary Consolidated Financial Data," "Selected Consolidated Financial Data" and "Capitalization" fairly present the information set forth therein on a basis consistent with that of the audited financial statements contained in the Registration Statement.

(k) Company's Accounting System. The Company and its subsidiary maintain a system of 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.

(m) Incorporation and Good Standing of the Company and its Subsidiary. Each of the Company and its subsidiary has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction in which it is organized with full corporate power and authority to own its properties and conduct its business as described in the prospectus, and is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which requires such qualification, except where the failure to be so qualified or in good standing, as applicable, would not have a Material Adverse Effect.

(n) Capitalization of the Subsidiary. All the outstanding shares of capital stock of Power Circuits, Inc. have been duly and validly authorized and issued and are fully paid and nonassessable, and, except for such restrictions under the Company's Amended and Restated Credit Agreement, as amended, except as described in or contemplated by the Prospectus and except where the existence of a security interest, claim, lien or encumbrance would not have a Material Adverse Effect, all outstanding shares of capital stock of Power Circuits, Inc. are owned by the Company directly free and clear of any security interests, claims, liens or encumbrances.

(o) No Prohibition on Subsidiary from Paying Dividends or Making other Distributions. Power Circuits, Inc. is not currently prohibited, directly or indirectly, from paying any dividends to the Company, from making any other distribution on its capital stock, from repaying to the Company any loans or advances to it from the Company or from transferring any of its property or assets to the Company or any other future subsidiary of the Company, except for such restrictions under the Company's Amended and Restated Credit Agreement, as amended, and except as described in or contemplated by the Prospectus.

(p) Capitalization and other Capital Stock Matters. The authorized, issued and outstanding capital stock of the Company is as set forth in the Prospectus under the caption "Capitalization" (other than for subsequent issuances, if any, pursuant to employee benefit plans described in the Prospectus or upon exercise of outstanding options or warrants described in the Prospectus). The Common Shares (including the Shares) conform in all material respects to the description thereof contained in the Prospectus. All of the issued and outstanding Common Shares (including the Shares to be sold by the Selling Stockholders) 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 Common Shares were issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. There are no authorized or 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 or its subsidiary other than those accurately described in the 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 the Prospectus accurately and fairly describes such plans, arrangements, options and rights.

(q) Stock Exchange Listing. The Shares are registered pursuant to Section 12(b) of the Exchange Act and are listed on the Nasdaq National Market, and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Shares under the Exchange Act or delisting the Common Shares from the Nasdaq National Market, nor has the Company received any notification that the Commission or the National Association of Securities Dealers, Inc. (together with its regulatory subsidiary NASD Regulation, Inc., the "NASD") is contemplating terminating such registration or listing. The Company is currently in compliance with all rules and regulations promulgated by the NASD and the Nasdaq National Market.

(r) No Consents, Approvals or Authorizations Required.

(s) Non-Contravention of Existing Instruments and Agreements. Neither the issue and sale of the Shares nor the consummation of any other of the transactions herein contemplated nor the fulfillment of the terms hereof will conflict with, result in a breach or violation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiary pursuant to, (i) the charter or by-laws of the Company or its subsidiary, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which the Company or its subsidiary is a party or bound or to which its or their property is subject or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company or its subsidiary of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or its subsidiary or any of its or their properties, except for such conflicts, breaches, violations or impositions that would not, singly or in the aggregate, have a Material Adverse Effect on the Company and except as otherwise set forth in the Prospectus.

(t) No Defaults or Violations. Neither the Company nor its subsidiary is in violation or default of (i) any provision of its charter or by-laws, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which it is a party or bound or to which its property is subject or (iii) any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or such subsidiary or any of its properties, as applicable, except any such violation or default which would not, singly or in the aggregate, result in a Material Adverse Change and except as otherwise disclosed in the Prospectus.

involving the Company or its subsidiary or its or their property is pending or, to the best knowledge of the Company, threatened that (i) could reasonably be expected to have a Material Adverse Effect on the performance of this Agreement or the consummation of any of the transactions contemplated hereby or (ii) could reasonably be expected to result in a Material Adverse Effect.

(v) All Necessary Permits, Etc. Except as set forth in the Prospectus, the Company and its 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 its subsidiary has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could result in a Material Adverse Change.

(w) Title to Properties. The Company and its subsidiary have good and marketable title to all the properties and assets reflected as owned in the financial statements referred to in Section 1(A)(i) above (or elsewhere in the Prospectus), in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, claims and other defects, except such as do not materially and adversely affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by the Company or its subsidiary. The real property, improvements, equipment and personal property held under lease by the Company or its 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 its subsidiary.

(x) Tax Law Compliance. The Company and its subsidiary have filed all necessary federal, state and foreign income and franchise tax returns or have properly requested extensions thereof 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 as may be being contested in good faith and by appropriate proceedings. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section 1(A)(i) 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 its subsidiary has not been finally determined. The Company is not aware of any tax deficiency that has been or might be asserted or threatened against the Company that could result in a Material Adverse Change.

(y) Intellectual Property Rights. Each of the Company and its subsidiary owns or possesses adequate rights to use all patents, patent rights or licenses, inventions, collaborative research agreements, trade secrets, know-how, trademarks, service marks, trade names and copyrights which are necessary to conduct its businesses as described in the Registration Statement and Prospectus and any document incorporated or deemed to be incorporated by reference in the Prospectus (an "Incorporated Document"); the expiration of any patents, patent rights, trade secrets, trademarks, service marks, trade names or copyrights would not result in a Material Adverse Change that is not otherwise disclosed in the Prospectus; except as set forth in the Prospectus, the Company has not received any notice of, and has no knowledge of, any infringement of or conflict with asserted rights of the Company by others with respect to any patent, patent rights, inventions, trade secrets, know-how, trademarks, service marks, trade names or copyrights; and except as set forth in the Prospectus, the Company has not received any notice of, and has no knowledge of, any infringement of or conflict with asserted rights of others with respect to any patent, patent rights, inventions, trade secrets, know-how, trademarks, service marks, trade names or copyrights which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, might have a Material Adverse Change. Except as set forth in the Prospectus, there is no claim being made against the Company regarding patents, patent rights or licenses, inventions, collaborative research, trade secrets, know-how, trademarks, service marks, trade names or copyrights. The Company and its subsidiary do not in the conduct of their business as now or

proposed to be conducted as described in the Prospectus infringe or conflict with any right or patent of any third party, or any discovery, invention, product or process which is the subject of a patent application filed by any third party, known to the Company or its subsidiary, which such infringement or conflict is reasonably likely to result in a Material Adverse Change.

(z) No Transfer Taxes or Other Fees. 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 and sale by the Company of the shares.

(aa) Company Not an "Investment Company". The Company is not, and after giving effect to the offering and the sale of the Shares and the application of the net proceeds thereof as described in the Prospectus, the Company will not be, an "investment company," as such term is defined in the Investment Company Act of 1940, as amended (the "Investment Company Act").

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

(cc) Labor Matters. To the best of Company's knowledge, no labor disturbance by the employees of the Company or its subsidiary exists or is imminent; and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its principal suppliers or its indirect sales representatives, which in each case would reasonably be expected to result in a Material Adverse Change.

(dd) No Price Stabilization or Manipulation. The Company has not taken and will not take, 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 Common Stock to facilitate the sale or resale of the Shares.

(ee) Lock-Up Agreements. Each officer and director of the company and each beneficial owner of one or more percent of the outstanding issued share capital of the Company has agreed to sign an agreement substantially in the form attached hereto as Exhibit A (the "Lock-Up Agreements"). The Company has provided to counsel for the Underwriters a complete and accurate list of all securityholders of the Company and the number and type of securities held by each securityholder. The Company has provided to counsel for the Underwriters true, accurate and complete copies of all of the Lock-Up Agreements presently in effect or effected hereby. The Company hereby represents and warrants and agrees that during the 90 days following the date of the Prospectus (the "Lock-Up Period"), the Company will not (i) release any of its officers, directors or other securityholders from any market stand-off agreements currently existing or hereafter effected or (ii) consent to or allow the removal of any transfer-restrictive legends from any certificate representing any Common Shares, in each case without the prior written consent of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇.

(ff) Related Party Transactions. There are no business relationships or related-party transactions involving the Company or any subsidiary or any other person required to be described in the Prospectus which have not been described as required.

(gg) No Unlawful Contributions or other Payments. Neither the Company nor its subsidiary nor, to the best of the Company's knowledge, any employee or agent of the Company or its 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 Prospectus.

(hh) Environmental Laws. Except as otherwise disclosed in the Prospectus, (i) the Company is in compliance with all rules, laws and regulations relating to the use, treatment, storage and disposal of toxic substances and protection of health or the environment ("Environmental Laws") which are applicable to its business, except where the failure to comply would not result in a Material Adverse Change, (ii) the Company has received no notice from any governmental authority or third party of an asserted claim under Environmental Laws, which claim is required to be disclosed in the Registration Statement and the Prospectus and any Incorporated Document, (iii) the Company is not currently aware that it will be required to make future material capital expenditures to comply with Environmental Laws and (iv) no property which is owned, leased or occupied by the Company has been designated as a Superfund site pursuant to the Comprehensive Response, Compensation, and Liability Act of 1980, as amended (42 U.S.C. § 9601, et seq.), or otherwise designated as a contaminated site under applicable state or local law.

(ii) ERISA Compliance. Except as otherwise disclosed in the Prospectus, the Company and its subsidiary 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 subsidiary 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 subsidiary or any of their ERISA Affiliates. No "employee benefit plan" established or maintained by the Company, its subsidiary 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 subsidiary 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 subsidiary 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.

(jj) Exchange Act Compliance. The Incorporated Documents, at the time they were or hereafter are filed with the Commission, complied with and will comply in all material respects with the requirements of the Exchange Act, and, when read together with the other information in the Prospectus, at the time the Registration Statement and any amendments thereto become effective and at the First Closing Date and the Second Closing Date, as the case may be, 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.

(kk) Exchange Act Reports Filed. The Company has filed all reports required to be filed pursuant to the Securities Act and the Exchange Act.

(ll) Conditions for Use of Form S-3. The Company has satisfied the conditions for the use of Form S-3, as set forth in the general instructions thereto, with respect to the Registration Statement.

The form and content of the Registration Statement complies with all applicable rules and regulations of the Commission.

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

B. Representations and Warranties of the Selling Stockholders. Each Selling Stockholder hereby represents, warrants and covenants as regarding itself only (and not as regarding any other Selling Stockholder) to each Underwriter as follows:

(a) The Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by or on behalf of such Selling Stockholder and is a valid and binding agreement of such Selling Stockholder, enforceable in accordance with its terms, except as rights to indemnification and contribution hereunder may be limited by applicable law or applicable public policy and except as the enforcement hereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

(b) The Custody Agreement and Power of Attorney. Each of the (i) Custody Agreement signed by such Selling Stockholder and [ ], a [ ], as custodian (the "Custodian"), relating to the deposit of the Shares to be sold by such Selling Stockholder hereunder (the "Custody Agreement") and (ii) Power of Attorney appointing certain individuals named therein as such Selling Stockholder's attorneys-in-fact (each, an "Attorney-in-Fact") to the extent set forth therein relating to the transactions contemplated hereby and by the Prospectus (the "Power of Attorney"), of such Selling Stockholder has been duly authorized, executed and delivered by such Selling Stockholder and is a valid and binding agreement of such Selling Stockholder, enforceable in accordance with its terms, except as rights to indemnification and contribution thereunder may be limited by applicable law or applicable public policy and except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles. Each Selling Stockholder agrees that the Shares to be sold by such Selling Stockholder on deposit with the Custodian are subject to the interests of the Underwriters, that the arrangements made for such custody are to that extent irrevocable, and that the obligations of such Selling Stockholder hereunder shall not be terminated, except as provided in this Agreement or in the Custody Agreement, by any act of the Selling Stockholder, by operation of law (to the extent permitted by law), by death or incapacity of such Selling Stockholder or by the occurrence of any other event. If such Selling Stockholder should die or become incapacitated, or in any other event should occur, before the delivery of the Shares to be sold by such Selling Stockholder hereunder, the documents evidencing the Shares to be sold by such Selling Stockholder then on deposit with the Custodian shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement and its Custody Agreement (to the extent permitted by law) as if such death, incapacity or other event had not occurred, regardless of whether or not the Custodian shall have received notice thereof.

(c) Title to Shares to be Sold. Such Selling Stockholder is the lawful owner of the Shares to be sold by such Selling Stockholder hereunder, and upon sale and delivery of, and payment for, such Shares, as provided herein, such Selling Stockholder will convey good and marketable title to such Shares, free and clear of all liens, encumbrances, equities and claims whatsoever.

(d) All Authorizations Obtained. Such Selling Stockholder has, and on the First Closing Date and the Second Closing Date will have, good and valid title to all of the Common Shares which may be sold by such Selling Stockholder pursuant to this Agreement on such date and the legal right and power, and all authorizations and approvals required by law and under its charter or by-laws, partnership agreement, trust agreement or other organizational documents to enter into this Agreement

(b) Securities Act Compliance. The Company will advise the Representatives promptly (i) when the Registration Statement or any post-effective amendment thereto shall have become effective, (ii) of receipt of any comments from the Commission, (iii) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Company 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.

(c) Blue Sky Compliance. The Company will cooperate with the Representatives and counsel for the Underwriters in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions (both national and foreign) 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 Company 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. The Company will, from time to time, prepare and file such statements, reports and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representatives may reasonably request for distribution of the Shares.

(d) Amendments and Supplements to the Prospectus and other Securities Act Matters. The Company will comply with the Securities Act and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus.

As used herein, the term "electronic Prospectus" means a form of Prospectus, and any amendment or supplement thereto, that meets each of the following conditions: (i) it shall be encoded in a format, satisfactory to the Representatives, that may be transmitted electronically over the internet or via other online distribution to offerees and purchasers of the Shares; and (ii) it shall disclose the same information as the paper Prospectus (or any amendment or supplement thereto), except to the extent that graphic and image material contained in the paper Prospectus (or such amendment or

supplement) cannot be presented in such electronic format, in which case such graphic and image material shall be replaced in the electronic Prospectus with a fair and accurate narrative description or tabular representation of such material, as appropriate. The Company hereby consents to distribution of the electronic Prospectus (including posting of the electronic Prospectus on the internet) by any of the Underwriters or their affiliates.

(f) Insurance. The Company shall maintain in full force and effect a Directors and Officers liability insurance in the minimum amount of $10 million which shall apply to the offering contemplated hereby.

(g) Notice of Subsequent Events. If at any time during the ninety (90) day period after the Registration Statement becomes effective, any rumor, publication or event relating to or affecting the Company shall occur as a result of which in your opinion the market price of the Company Shares has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to or amendment of the Prospectus), the Company will, after written notice from you advising the Company to the effect set forth above, forthwith prepare, consult with you concerning the substance of and disseminate a press release or other public statement, reasonably satisfactory to you, responding to or commenting on such rumor, publication or event.

(k) Periodic Reporting Obligations. During the Prospectus Delivery Period, the Company shall file, on a timely basis, with the Commission and the Nasdaq National Market all reports and documents required to be filed under the Exchange Act within the time periods required by the Exchange Act and the rules of the Nasdaq National Market.

Without the prior written consent of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, the Company will not offer, sell or contract to sell, or otherwise dispose of or enter into any transaction which is designed to, or could be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company) directly or indirectly, or announce the offering of, any other Common Shares or any securities convertible into, or exchangeable for, Common Shares; provided, however, that the Company may (i) issue and sell Common Shares pursuant to any director or employee stock option plan, stock ownership plan or dividend reinvestment plan of the Company in effect at the date of the Prospectus and described in the Prospectus so long as none of those shares may be transferred and the Company shall enter stop transfer instructions with its transfer agent and registrar against the transfer of any such Common Shares, and (ii) the Company may issue Common Shares issuable upon the conversion of securities or the exercise of warrants outstanding at the date of the Prospectus and described in the Prospectus, provided that the above consent obligation is expressly assumed in writing by the recipient of the Common Shares or other securities (with a copy to ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and its counsel) and that the certificates for such Common Shares or other securities contain a transfer-restrictive legend to such effect. These restrictions terminate after the close of trading of the Shares on the final day of the Lock-Up Period.

(a) Agreement Not to Offer or Sell Additional Securities. Such Selling Stockholder will not, during the Lock-Up Period, make a disposition of Securities (as defined in Exhibit A hereto) now owned or hereafter acquired directly by such person or with respect to which such person has or hereafter acquires the power of disposition, otherwise than (i) as a bona fide gift or gifts, provided the donee or donees thereof agree in writing to be bound by this restriction, (ii) as a distribution to partners or Stockholders of such person, provided that the distributees thereof agree in writing to be bound by the terms of this restriction, (iii) with respect to dispositions of Common Shares acquired on the open market or (iv) with the prior written consent of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Inc. The foregoing restriction has been expressly agreed to preclude the holder of the Securities from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a disposition of Securities during the Lock-Up period, even if such Securities would be disposed of by someone other than such holder. Such prohibited hedging or other transactions would include, without limitation, any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any Securities or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from Securities. Furthermore, such Selling Stockholder also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent against the transfer of the Securities held by such Selling Stockholder except in compliance with this restriction.

Each of the Company and the Principal Selling Stockholders, jointly and severally, agrees 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 and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, which consent shall not be unreasonably withheld), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) 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 430A 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) upon any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus 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) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; or (iv) in whole or in part upon any failure of the Company or the Principal Selling Stockholders to perform their respective obligations hereunder or under law; or (v) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials provided by the Company or based upon written information furnished by or on behalf of the Company including, without limitation, slides, videos, films or tape recordings, used in connection with the marketing of the Shares, including, without limitation, statements communicated to securities analysts employed by the Underwriters; or (vi) 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 Shares 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), (ii), (iii), (iv) or (v) above, provided that the Company and the Principal Selling Stockholders shall not be liable under this clause (vi) 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 controlling person for any and all expenses (including the fees and disbursements of counsel

chosen by ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇) as such expenses are reasonably incurred by such Underwriter or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, that such loss, claim, damage, liability or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and provided, further, that with respect to any preliminary prospectus, the foregoing indemnity agreement shall not inure to the benefit of any Underwriter from whom the person asserting any loss, claim, damage, liability or expense purchased Shares, or any person controlling such Underwriter, if copies of the Prospectus were timely delivered to the Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or expense; provided, further, that the liability of each Principal Selling Stockholder under the foregoing indemnity agreement shall not exceed an amount equal to the product of (a) the number of Shares sold by such Principal Selling Stockholder, and (b) the initial public offering price per Share, less the underwriting discounts and commissions per Share, as set forth on the front cover page of the Prospectus. The indemnity agreement set forth in this Section 7(a)(1) shall be in addition to any liabilities that the Company and the Principal Selling Stockholders may otherwise have.

(2) By the Other Selling Stockholders. Each of the Other Selling Stockholders, severally and not jointly, agrees 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 and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Other Selling Stockholder, which consent shall not be unreasonably withheld), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) 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 430A 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) upon any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus 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, in the case of subparagraphs (i) and (ii) of this Section 7(a)(2) to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company or such Underwriter by such Other Selling Stockholder, directly or through such Other Selling Stockholder's representatives, specifically for use in the preparation of the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); or (iii) in whole or in part upon any inaccuracy in the representations and warranties of such Other Selling Stockholder contained herein; or (iv) in whole or in part upon any failure of such Other Selling Stockholder to perform its obligations hereunder or under law; or (v) 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 Shares 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), (ii), (iii) or (iv) above, provided that such Other Selling Stockholder shall not be liable under this clause (v) 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 controlling person for any and all expenses (including the fees and disbursements of counsel chosen by ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇) as such expenses are reasonably incurred by such Underwriter or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that with respect to any preliminary prospectus, the foregoing indemnity agreement shall not inure to the benefit of any Underwriter from whom the person asserting any loss, claim, damage, liability or expense purchased Shares, or any person controlling such Underwriter, if copies of the Prospectus were timely delivered to the Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or expense; provided, further, that the liability of such Other Selling Stockholder under the foregoing indemnity agreement shall be limited to an amount equal to the product of (a) the number of Shares sold by such Other Selling Stockholder, and (b) the initial public offering price per Share, less the underwriting discounts and commissions per Share, as set forth on the front cover page of the Prospectus. The indemnity agreement set forth in this Section 7(a)(2) shall be in addition to any liabilities that the Other Selling Stockholders may otherwise have.

(b) Indemnification of the Company, its Directors and Officers and Selling Stockholders. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement, each of the Selling Stockholders and each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer, Selling Stockholder or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus 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 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, any preliminary prospectus, the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company and the Selling Stockholders by the Representatives expressly for use therein; and to reimburse the Company, or any such director, officer, Selling Stockholder or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer, Selling Stockholder or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 7(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Information Provided by the Underwriters. Each of the Company, each of the Selling Stockholders and each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Securities Act or the Exchange Act, hereby acknowledges that the only information that the Underwriters have furnished to the Company expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) are the statements set forth in the Prospectus under the caption "Underwriting" as follows: (i) in the table in the first paragraph, (ii) in the first, second and third sentences of the subsection titled "Dealers' compensation," (iii) in the subsection titled "Discretionary accounts," (iv) in the subsection titled "Directed share program," (v) in the first sentence and the second paragraph of the subsection titled "Online activities" and (vi) in the final three sentences of the first paragraph of the subsection titled "Qualified Independent Underwriter"; and the Underwriters confirm that such statements are correct.

(d) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 7 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 7, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability hereunder to the extent it is not materially prejudiced as a proximate result of such failure and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party's election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ in the case of Section 7(b) and Section 8), representing the indemnified parties who are parties to such action), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(e) Settlements. The indemnifying party under this Section 7 shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified

party for fees and expenses of counsel as contemplated by Section 7(d) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(f) Contribution. If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party in such proportion as is appropriate to reflect the relative benefits received by the Company and the Principal Selling Stockholders, each Other Selling Stockholder 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 Company and each of the Principal Selling Stockholders, each Other Selling Stockholder 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 Company and the Principal Selling Stockholders, each Other Selling Stockholder and the Underwriters shall be deemed to be in the same proportions as the total net proceeds (before deducting expenses) received by the Company and the Principal Selling Stockholders and each Other Selling Stockholder, respectively, from the sale of the Shares sold by them in the offering bears to the total underwriting discounts and commissions received by the Underwriters in connection with the sale of such Shares, in each case as described in 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 Company or a Principal Selling Stockholder, an Other 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 Company, each Selling Stockholder and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(f) 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 Section 7(f). 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 Section 7(f) 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 (f), (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 Selling Stockholder shall be required to contribute any amount in excess of the net proceeds (i.e., gross proceeds less underwriting discounts and commissions) received by such Selling Stockholder from its sale of Shares hereunder, and (iii) 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 in this Section 7(f) to contribute are several in proportion to their respective underwriting obligations and not joint.

(g) Timing of Any Payments of Indemnification. Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred, but in all cases, no later than forty-five (45) days of invoice to the indemnifying party.

(h) Survival. The indemnity and contribution agreements contained in this Section 7 and the representation and warranties 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 Company, its directors or officers, any Selling Stockholder or any persons controlling the Company or any Selling Stockholder, and (ii) acceptance of any Shares and payment therefor hereunder. The indemnity and contribution agreements contained in this Section 7 shall remain operative and in full force and effect, regardless of any termination of this Agreement. A successor to any Underwriter, or to the Company, its directors or officers, any Selling Stockholder or any person controlling the Company or any Selling Stockholder, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 7.

(i) Indemnification of Qualified Independent Underwriter. Without limitation and in addition to its obligations under the other subsections of this Section 7, the Company agrees to indemnify and hold harmless ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and each person, if any, who controls ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ within the meaning of the Securities Act or the Exchange Act from and against any loss, claim, damage, liabilities or expense, as incurred, arising out of or based upon ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇' acting as a "qualified independent underwriter" (within the meaning of Rule 2720 to the NASD's Conduct Rules) in connection with the offering contemplated by this Agreement, and agrees to reimburse each such indemnified person for any legal or other expense reasonably incurred by them in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or expense results from the gross negligence or willful misconduct of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇. The indemnity agreement set forth in this Section 7(i) shall be in addition to any liabilities that the Company may otherwise have.

(j) Indemnification for Directed Share Program. The Company agrees to indemnify and hold harmless ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and its affiliates and each person, if any, who controls ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ or its affiliates within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act ("▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ Entities"), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to participants in connection with any Directed Share Program approved by the Underwriters, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) the failure of any participant to pay for and accept delivery of Directed Shares that the participant has agreed to purchase; or (iii) related to, arising out of, or in connection with any Directed Share Program approved by the Underwriters other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or willful misconduct of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ Entities. The indemnity agreement set forth in this Section 7(j) shall be in addition to any liabilities that the Company may otherwise have.

(k) Acknowledgements of Parties. The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations regarding the

provisions hereof including, without limitation, the provisions of this Section 7, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 7 fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement and Prospectus as required by the Securities Act and the Exchange Act.

Section 8. Default of One or More of the Several Underwriters.

If, on the First Closing Date or the Second Closing Date, as the case may be, any one or more of the several Underwriters shall fail or refuse to purchase Shares that it or they have agreed to purchase hereunder on such date, and the aggregate number of Common Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed ten percent (10%) of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the number of Firm Common Shares set forth opposite their respective names on Schedule A bears to the aggregate number of Firm Shares 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 Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the First Closing Date or the Second Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares and the aggregate number of Shares with respect to which such default occurs exceeds 10% of the aggregate number of Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Shares 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 5 and Section 7 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Company shall have the right to postpone the First Closing Date or the Second Closing Date, as the case may be, 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 8. Any action taken under this Section 8 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 9. Termination of this Agreement.

This Agreement may be terminated by the Representatives by notice given to the Company if (a) at any time after the execution and delivery of this Agreement and prior to the First Closing Date (i) trading or quotation in any of the Company's securities shall have been suspended or limited by the Commission or by the Nasdaq Stock Market, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the NASD; (ii) a general banking moratorium shall have been declared by any of federal, New York or California 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 change in United States' or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Common Shares in the manner and on the terms contemplated in 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; or (b) in the case of any of the events specified 9(a)(i)-(v), such event singly or together with any other event, makes it, in your judgment, impracticable or inadvisable to market the Common Shares in the manner and on the terms contemplated in the Prospectus. Any termination pursuant to this Section 9 shall be without liability on the part of (x) the Company or the Selling Stockholders to any Underwriter, except that the Company and the Selling Stockholders shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Sections 5 and 6 hereof, (y) any Underwriter to the Company or the Selling Stockholders or any person controlling the Company or the Selling Stockholders, or (z) of any party hereto to any other party except that the provisions of Section 7 shall at all times be effective and shall survive such termination.

Section 10. Representations and Indemnities to Survive Delivery.

The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers, of any Selling Stockholder, or of any person controlling the company or any Selling Stockholder and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of its or their partners, officers or directors or any controlling person or any Selling Stockholder, as the case may be, and will survive delivery of and payment for the Shares sold hereunder and such indemnities and agreements shall survive any termination of this Agreement.

If one or more of the Selling Stockholders shall fail to sell and deliver to the Underwriters the Shares to be sold and delivered by such Selling Stockholders at the First Closing Date or the Second Closing Date pursuant to this Agreement, then the Underwriters may at their option, by written notice from the Representatives to the Company and the Selling Stockholders, either (i) terminate this Agreement without any liability on the part of any Underwriter or, except as provided in Sections 5, 6, and 7 hereof, the Company or the Selling Stockholders, or (ii) purchase the shares which the Company and other Selling Stockholders have agreed to sell and deliver in accordance with the terms hereof, or (iii) purchase the shares mentioned in the preceding clause (ii) and elect to purchase a number of additional Common Shares from the Company equal to the number of Shares which the Selling Stockholders failed to deliver, in which case the term "Shares" as used in this Agreement shall be deemed to refer also to such additional Common Shares, and the Company agrees to sell such Shares to the Underwriters upon such election.
