Ladies and Gentlemen:

Applied Optoelectronics, Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the several Underwriters named in Schedule I hereto (the “Underwriters”), and certain stockholders of the Company named in Schedule II hereto (the “Selling Stockholders”) severally and not jointly propose, subject to the terms and conditions stated herein, to sell to the Underwriters, an aggregate of 3,000,000 shares of the Company’s Common Stock, par value $0.001 per share (the “Common Stock), of which (a) 1,575,235 shares are to be issued and sold by the Company, and (b) 1,424,765 shares are to be sold by the Selling Stockholders, each Selling Stockholder selling the number of shares set forth opposite such Selling Stockholder’s name in Schedule II hereto. The aggregate of 3,000,000 shares to be purchased from the Company and the Selling Stockholders are called the “Firm Shares.” In addition, the Company has agreed to sell to the Underwriters, upon the terms and conditions stated herein, up to an additional 450,000 shares of Common Stock (the “Additional Shares”). The Firm Shares and the Additional Shares are collectively referred to in this Agreement as the “Shares.” ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Associates, Inc. and ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. are acting as the representatives of the several Underwriters and in such capacity are referred to in this Agreement as the “Representatives.”

The Company wishes to confirm as follows its agreement with you and the other several Underwriters, on whose behalf you are acting, in connection with the several purchases of the Shares from the Company.

1. Registration Statement and Prospectus. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), a registration statement on Form S-1 (File No. 333-194379), including a prospectus subject to completion, relating to the Shares. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, at the time when it becomes effective and as thereafter amended by any post-effective amendment, is referred to in this Agreement as the “Registration Statement.” The prospectus in the form included in the Registration Statement or, if the prospectus included in the Registration Statement omits certain information in reliance upon Rule 430A under the Act and such information is thereafter included in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act or as part of a post-effective amendment to the Registration Statement after the Registration Statement becomes effective, the prospectus as so filed, is referred to in this Agreement as the “Prospectus.” If the Company files another registration statement with the Commission to register a portion of the Shares pursuant to Rule 462(b) under the Act (the “Rule 462 Registration Statement”), then any reference to “Registration Statement” herein shall be deemed to include the registration statement on Form S-1 (File No. 333-194379) and the Rule 462 Registration Statement, as each such registration statement may be amended pursuant to the Act. The prospectus subject to completion in the form included in the Registration Statement at the time of the initial filing of such Registration Statement to the Commission and as such prospectus is amended from time to time until the date of the Prospectus is referred to in this Agreement as the “Preliminary Prospectus.” For purposes of this Agreement, “free writing prospectus” has the meaning ascribed to it in Rule 405 under the Act, and “Issuer Free Writing Prospectus” shall mean each free writing prospectus prepared by or on behalf of the Company or used or referred to by the Company in connection with the offering of the Common Stock. “Time of Sale Information” shall mean the Preliminary Prospectus together with the free writing prospectuses, if any, each identified in item (a) of Annex A hereto, the pricing information set forth in item (b) of Annex A and (c) a pricing term sheet in substantially the form of Annex B. All references in this Agreement to the Registration Statement, the Rule 462 Registration Statement, a Preliminary Prospectus, the Prospectus or the Time of Sale Information, or any amendments or supplements to any of the foregoing, shall be deemed to refer to and include any documents incorporated by reference therein, and shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

2. Agreements to Sell and Purchase. Upon the terms and conditions set forth herein, (i) the Company agrees to issue and sell an aggregate of 1,575,235 Firm Shares to the Underwriters and (ii) the Selling Stockholders, severally and not jointly, agree to sell an aggregate of 1,424,765 Firm Shares to the Underwriters, each Selling Stockholder selling the number of Firm Shares set forth opposite such Selling Stockholder’s name on Schedule II hereto. Upon the basis of the representations, warranties and agreements of the Company and the Selling Stockholders herein contained and subject to all the terms and conditions set forth herein, each Underwriter agrees, severally and not jointly, to purchase from the Company and the Selling Stockholders at a purchase price of $22.916 per Share (the “purchase price per Share”), the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto.

The Company hereby also agrees to sell to the Underwriters, and, upon the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions set forth herein, the Underwriters shall have the right for 30 days from the date of the Prospectus to purchase from the Company up to 450,000 Additional Shares at the purchase price per Share for the Firm Shares. If any Additional Shares are to be purchased, each Underwriter, severally and not jointly, agrees to purchase the number of Additional Shares (subject to such adjustments as you may determine to avoid fractional shares) that bears the same proportion to the total number of Additional Shares to be purchased by the Underwriter as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto bears to the total number of Firm Shares. The option to purchase Additional Shares may be exercised at any time within 30 days after the date of the Prospectus, but no more than once.

3. Terms of Public Offering. The Company and the Selling Stockholders have been advised by you that the Underwriters propose to make a public offering of their respective portions of the Shares as soon after the Registration Statement and this Agreement have become effective as in your judgment is advisable and initially to offer the Shares upon the terms set forth in the Prospectus.

Not later than 12:00 p.m. (noon) on the second business day following the date the Shares are released by the Underwriters for sale to the public, the Company shall deliver or cause to be delivered copies of the Prospectus in such quantities and at such places as the Representatives shall have reasonably requested by 5:00 p.m. on the date the Shares are released by the Underwriters for sale to the public.

4. Delivery of the Shares and Payment Therefor.

Such notice may be given at any time within 30 days after the date of the Prospectus and must set forth (i) the aggregate number of Additional Shares as to which the Underwriters are exercising the option and (ii) the names and denominations in which the certificates for which the Additional Shares are to be registered. The place of closing for the Additional Shares and the Additional Closing Date may be varied by agreement between you and the Company.

Payment for the Shares sold by the Company hereunder shall be delivered by the Representatives to the Company. Payment for the Shares sold by the Selling Stockholders hereunder shall be delivered by the Representatives to the Custodian (as defined herein).

It is understood that the Representatives have been authorized, for their own respective account and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price per Share for the Firm Shares and the Additional Shares, if any, that the Underwriters have agreed to purchase. Each of ▇▇▇▇▇▇▇ ▇▇▇▇▇ and Associates, Inc. and ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., individually and not as Representatives of the Underwriters, may, but shall not be obligated to, make payment for any Shares to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the Closing Date or the Additional Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

Each Selling Stockholder hereby agrees that (i) it will pay all stock transfer taxes, stamp duties and other similar taxes, if any, payable upon the sale or delivery of the Shares to be sold by such Selling Stockholder to the several Underwriters, or otherwise in connection with the performance of such Selling Stockholder’s obligations hereunder and (ii) the Custodian is authorized to deduct for such payment any such amounts from the proceeds to such Selling Stockholder hereunder and to hold such amounts for the account of such Selling Stockholder with the Custodian under the Custody Agreement (as defined herein).

5. Covenants and Agreements.

5.1 Of the Company. The Company covenants and agrees with the several Underwriters as follows:

(a) The Company will use its best efforts to cause the Registration Statement and any amendments thereto to become effective, if it has not already become effective, and will advise you promptly and, if requested by you, will confirm such advice in writing (i) when the Registration Statement has become effective and the time and date of any filing of any post-effective Registration Statement or any amendment or supplement to any Preliminary Prospectus or the Prospectus and the time and date that any post-effective amendment to the Registration Statement becomes effective, (ii) if Rule 430A under the Act is employed, when the Prospectus has been timely filed pursuant to Rule 424(b) under the Act, (iii) of the receipt of any comments of the Commission, or any request by the Commission for amendments or supplements to the Registration Statement, any Preliminary Prospectus or the Prospectus or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of the suspension of qualification of the Shares for offering or sale in any jurisdiction or the initiation of any proceeding for such purposes and (v) within the period of time referred to in Section 5.1(h) hereof, of any change in the Company’s condition (financial or other), business, prospects, properties, net worth or results of operations, or of any event that comes to the attention of the Company that makes any statement made in the Registration Statement or the Prospectus (as then amended or supplemented) untrue in any material respect or that requires the making of any additions thereto or changes therein in order to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading in any material respect, or of the necessity to amend or supplement the Prospectus (as then amended or supplemented) to comply with the Act or any other law. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, the Company will make every reasonable effort to obtain the withdrawal or lifting of such order at the earliest possible time. The Company will provide the Underwriters with copies of the form of Prospectus, in such number as the Underwriters may reasonably request, and file with the Commission such Prospectus in accordance with Rule 424(b) under the Act before the close of business on the first business day immediately following the date hereof.

(b) The Company will furnish to you, without charge, two signed duplicate originals of the Registration Statement as originally filed with the Commission and of each amendment thereto, including financial statements and all exhibits thereto, and will also furnish to you, without charge, such number of conformed copies of the Registration Statement as originally filed and of each amendment thereto as you may reasonably request.

(c) The Company will promptly file with the Commission any amendment or supplement to the Registration Statement or the Prospectus that may, in the judgment of the Company or the Representatives be required by the Act or requested by the Commission.

(d) The Company will furnish a copy of any amendment or supplement to the Registration Statement or to the Prospectus or any Issuer Free Writing Prospectus to you and counsel for Underwriters and obtain your consent prior to filing any of those with the Commission, which consent shall not be unreasonably withheld or delayed.

(e) The Company will not make any offer relating to the Common Stock that would constitute an Issuer Free Writing Prospectus without your prior consent.

(f) The Company will retain in accordance with the Act all Issuer Free Writing Prospectuses not required to be filed pursuant to the Act; and if at any time after the date hereof any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify you and, upon your request, to file such document and to prepare and furnish without charge to each Underwriter as many copies as they may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance;

(g) Prior to the execution and delivery of this Agreement, the Company has delivered or will deliver to you, without charge, in such quantities as you have requested or may hereafter reasonably request, copies of each form of the Preliminary Prospectus. Consistent with the provisions of Section 5.1(h) hereof, the Company consents to the use, in accordance with the provisions of the Act and with the securities or Blue Sky laws of the jurisdictions in which the Shares are offered by the several Underwriters and by dealers, prior to the date of the Prospectus, of each Preliminary Prospectus so furnished by the Company.

(h) As soon after the execution and delivery of this Agreement as is practicable and thereafter from time to time for such period as in the reasonable opinion of counsel for the Underwriters a prospectus is required by the Act to be delivered in connection with sales by any Underwriter or a dealer (the “Prospectus Delivery Period”), and for so long a period as you may request for the distribution of the Shares, the Company will deliver to each Underwriter and each dealer, without charge, as many copies of the Prospectus and the Time of Sale Information (and of any amendment or supplement thereto) as they may reasonably request. The Company consents to the use of the Prospectus and the Time of Sale Information (and of any amendment or supplement thereto) in accordance with the provisions of the Act and with the securities or Blue Sky laws of the jurisdictions in which the Shares are offered by the several Underwriters and by all dealers to whom Shares may be sold, both in connection with the offering and sale of the Shares and for such period of time thereafter as the Prospectus is required by the Act to be delivered in connection with sales by any Underwriter or dealer. If at any time prior to the later of (i) the completion of the distribution of the Shares pursuant to the offering contemplated by the Registration Statement or (ii) the expiration of prospectus delivery requirements with respect to the Shares under Section 4(3) of the Act and Rule 174 thereunder, any event shall occur that in the judgment of the Company or in the opinion of counsel for the Underwriters is required to be set forth in the Prospectus (as then amended or supplemented) or should be set forth therein in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Prospectus to comply with the Act or any other law, the Company will forthwith prepare and, subject to Section 5.1(a) hereof, file with the Commission and use its best efforts to cause to become effective as promptly as possible an appropriate supplement or amendment thereto, and will furnish to each Underwriter who has previously requested Prospectuses, without charge, a reasonable number of copies thereof.

(i) The Company will cooperate with you and counsel for the Underwriters in connection with the registration or qualification of the Shares for offering and sale by the several Underwriters and by dealers under the securities or Blue Sky laws of such jurisdictions as you may reasonably designate and will file such consents to service of process or other documents as may be reasonably necessary in order to effect and maintain such registration or qualification for so long as required to complete the distribution of the Shares; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to general service of process in suits, other than those arising out of the offering or sale of the Shares, as contemplated by this Agreement and the Prospectus, in any jurisdiction where it is not now so subject. In the event that the qualification of the Shares in any jurisdiction is suspended, the Company shall so advise you promptly in writing.

(j) The Company will make generally available to its security holders a consolidated earnings statement (in form complying with the provisions of Rule 158), which need not be audited, covering a twelve-month period commencing after the effective date of the Registration Statement and the Rule 462 Registration Statement, if any, and ending not later than 15 months thereafter, as soon as practicable after the end of such period, which consolidated earnings statement shall satisfy the provisions of Section 11(a) of the Act.

(k) During the period ending three years from the date hereof, the Company will furnish to you and, upon your request, to each of the other Underwriters, (i) as soon as available, a copy of each proxy statement, quarterly or annual report or other similar public report of the Company mailed to stockholders or filed with the Commission, FINRA or the Nasdaq Stock Market (“NASDAQ”) or any national securities exchange and (ii) from time to time such other public information concerning the Company as you may reasonably request. The Company shall be deemed to have furnished the required information if such information has been filed on ▇▇▇▇▇.

(l) If this Agreement shall terminate or shall be terminated after execution pursuant to any provision hereof (except pursuant to a termination under Section 11 hereof) or if this Agreement shall be terminated by the Underwriters because of any inability, failure or refusal on the part of the Company to perform in all material respects any agreement herein or to comply in all material respects with any of the terms or provisions hereof or to fulfill in all material respects any of the conditions of this Agreement, the Company agrees to reimburse you and the other Underwriters for all out-of-pocket expenses (including travel expenses and reasonable fees and expenses of counsel for the Underwriters, but excluding wages and salaries paid by you or the other Underwriters) reasonably incurred by you in connection herewith.

(m) The Company will apply the net proceeds from the sale of the Shares to be sold by it hereunder in accordance in all material respects with the statements under the caption “Use of Proceeds” in the Prospectus.

(n) [Reserved.]

(o) For a period commencing on the date hereof and ending on the 90th day after the date of the Prospectus (the “Lock-Up Period”), the Company will not, directly or indirectly, (1) offer for sale, sell, pledge or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock or securities convertible into or exchangeable for Common Stock (other than the Common Stock issued pursuant to employee benefit plans, equity-based compensation plans or other employee compensation plans existing on the date hereof or pursuant to currently outstanding options, warrants or rights described in the Registration Statement), or sell or grant options, rights or warrants with respect to any shares of Common Stock or securities convertible into or exchangeable for Common Stock (other than the grant of options pursuant to option plans existing on the date hereof and described in the Registration Statement), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) file or cause to be filed a registration statement, including any amendments, with respect to the registration of any shares of Common Stock or securities convertible, exercisable or exchangeable into Common Stock or any other securities of the Company (other than any registration statement on Form S-8 with respect to the Company’s existing equity-based compensation plans as described in the Registration Statement) or (4) publicly disclose the intention to do any of the foregoing, in each case without the prior written consent of the Representatives on behalf of the Underwriters. Notwithstanding the foregoing, if during any period that the Company is not an Emerging Growth Company and (1) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or announces material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed in the preceding paragraph shall continue to apply until the expiration of the 18-day period beginning on the date of issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless the Representatives, on behalf of the Underwriters, waive such extension in writing. Written notice of any extension of the Lock-Up Period pursuant to the previous sentence will be promptly delivered by the Company to the Representatives. The Representatives agree that proper written notice may be delivered by the Company by filing a Form 8-K disclosing an extension of the initial 90-day restriction period. Without the prior written consent of the Representatives, the Company shall not file any Form 8-K disclosing that the 90-day restricted period (or any extension thereof) has expired unless required by law in the opinion of the Company’s legal counsel.

(p) If the Representatives, in their sole discretion, agree to release or waive the restrictions set forth in Section 5.1(o) above or a Lock-Up Agreement in the form of Exhibit A attached hereto (“Lock-Up Agreement”), in either case for an officer or director of the Company, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit B attached hereto through a major news service at least two (2) business days before the effective date of the release or waiver.

(q) Prior to the Closing Date or the Additional Closing Date, as the case may be, the Company will furnish to you, as promptly as possible, copies of any unaudited interim consolidated financial statements of the Company and its subsidiaries for any period subsequent to the periods covered by the financial statements appearing in the Prospectus.

(r) The Company will comply with all provisions of any undertakings contained in the Registration Statement.

(s) The Company will not at any time, directly or indirectly, take any action designed, or which might reasonably be expected to cause or result in, or which will constitute, stabilization or manipulation (in each case, within the meaning of the Act or the Exchange Act and the rules and regulations promulgated thereunder) of the price of the shares of Common Stock to facilitate the sale or resale of any of the Shares.

(t) The Company will timely file with NASDAQ all documents and notices required by the NASDAQ of companies that have or will issue securities that are traded on the NASDAQ.

(u) The Company shall engage and maintain, at its expense, a transfer agent and, if necessary under the jurisdiction of its incorporation or the rules of any national securities exchange on which the Common Stock will be listed, a registrar (which, if permitted by applicable laws and rules may be the same entity as the transfer agent) for the Common Stock.

(v) The Company will promptly notify the Representatives if the Company ceases to be an Emerging Growth Company at any time prior to the later of (a) completion of the distribution of the Shares within the meaning of the Act and (b) completion of the Lock-Up Period (including any extension thereof).

5.2 Of Each Selling Stockholder. Each Selling Stockholder, severally as to itself and not jointly, covenants and agrees with the several Underwriters as follows:

(a) Such Selling Stockholder will execute and deliver a Lock-Up Agreement prior to the effectiveness of the Registration Statement.

(b) Such Selling Stockholder will review the Prospectus and will comply with all agreements and satisfy all conditions on its part to be complied with or satisfied pursuant to this Agreement on or prior to the Closing Date and will advise the Underwriters prior to the Closing Date if any statements to be made on behalf of such Selling Stockholder in the certificate contemplated by Section 9(p) hereof would be inaccurate if made as of the Closing Date.

(c) On the Closing Date, all stock transfer and other taxes (other than income taxes) that are required to be paid in connection with the sale and transfer of the Firm Shares to be sold by such Selling Stockholder to the Underwriters hereunder will have been fully paid for by such Selling Stockholder and all laws imposing such taxes will have been fully complied with.

(d) In order to document the Underwriters’ compliance with the reporting and withholding provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated thereunder, with respect to the transactions herein contemplated, such Selling Stockholder shall deliver to you at least two days prior to the Closing Date a properly completed and executed United States Treasury Department Substitute Form W-9 or an appropriate Form W-8, as applicable.

6. Representations and Warranties.

6.1 Of the Company. The Company hereby represents and warrants to each Underwriter on the date hereof, and shall be deemed to represent and warrant to each Underwriter on the Closing Date and the Additional Closing Date, as the case may be, that:

(a) The Company was not at the time of initial filing of the Registration Statement and at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Act) of the Common Stock, is not on the date hereof and will not be on the applicable Delivery Date an “ineligible issuer” (as defined in Rule 405 under the Act).

(b) The Registration Statement conformed, and any amendment to the Registration Statement filed after the date hereof will conform in all material respects when filed, to the requirements of the Act. The most recent Preliminary Prospectus conformed, and the Prospectus will conform, in all material respects to the requirements of the Act when filed with the Commission pursuant to Rule 424(b).

(c) The Registration Statement does 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 not misleading; provided, that no representation or warranty is made as to information contained in or omitted from the Registration Statement in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof.

(d) The Prospectus 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; provided that no representation or warranty is made as to information contained in or omitted from the Prospectus in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof.

(e) The Time of Sale Information does not, and will not at the time of sale of the Shares, 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; provided that no representation or warranty is made as to information contained in or omitted from the Time of Sale Information in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof.

(f) Each Issuer Free Writing Prospectus (including, without limitation, any road show that is a free writing prospectus under Rule 433 under the Act), when considered together with the Time of Sale Information at the time of sale of the Shares, did 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; provided that no representation or warranty is made as to information contained in or omitted from the Time of Sale Information in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof.

(g) Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Act on the date of first use, and the Company has complied with all prospectus delivery and any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Act. The Company has not made any offer relating to the Stock that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives. The Company has retained in accordance with the Act all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Act. The Company has taken all actions necessary so that any “road show” (as defined in Rule 433 under the Act) in connection with the offering of the Stock will not be required to be filed pursuant to the Act.

(h) From the time of initial filing of the Registration Statement to the Commission (or, if earlier, the first date on which the Company engaged directly or through any person authorized to act on its behalf in any Testing-the-Waters Communication) through the date hereof, the Company has been and is an “emerging growth company,” as defined in Section 2(a) of the Act (an “Emerging Growth Company”). “Testing-the-Waters Communication” means any oral or written communication with potential investors undertaken in reliance on Section 5(d) of the Act.

(i) The Company (i) has not alone engaged in any Testing-the-Waters Communications other than Testing-the-Waters Communications with the consent of the Representatives with entities that the Company believes are qualified institutional buyers within the meaning of Rule 144A under the Act or institutions that the Company believes are accredited investors within the meaning of Rule 501 under the Act and (ii) has not authorized anyone other than the Representatives to engage in Testing-the-Waters Communications. The Company reconfirms that the Representatives have been authorized to act on its behalf in undertaking Testing-the-Waters Communications.

(o) The issued shares of capital stock of each of the Company’s subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are owned by the Company free and clear of any security interests, liens, encumbrances, equities or claims, except those identified in the Registration Statement or the Prospectus.

There is no action, suit, inquiry, proceeding or investigation by or before any court or governmental or other regulatory or administrative agency or commission pending or, to the knowledge of the Company, threatened, against or involving the Company or its subsidiaries, that would reasonably be expected to individually or in the aggregate prevent or adversely affect the transactions contemplated by this Agreement or result in a Material Adverse Effect, nor to the Company’s knowledge, is there any basis for any such action, suit, inquiry, proceeding or investigation.

(aa) The Company and each of its subsidiaries have filed all tax returns required to be filed (other than certain state or local tax returns, as to which the failure to file, individually or in the aggregate, would not have a Material Adverse Effect), which returns are complete and correct, and neither the Company nor any subsidiary is in default in the payment of any taxes that were payable pursuant to said returns or any assessments with respect thereto, other than those (i) that are being contested in good faith or (ii) that, if not paid, would not reasonably be expected to have a Material Adverse Effect.

(qq) The Company has procured Lock-Up Agreements, in the form of Exhibit A attached hereto, from each of the Company’s executive officers and directors, and from each of the Selling Stockholders.

(ss) The Company and each of its subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which it is engaged; and neither the Company nor any of its subsidiaries has reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a comparable cost.

(tt) To the Company’s knowledge, the Company and its subsidiaries and any “employee benefit plan” (as defined under ERISA) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA and all other applicable state and federal laws. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group or organization described in Sections 414(b), (c), (m) or (o) of the Code of which the Company or such subsidiary is a member. No “reportable event” (as defined in ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined in ERISA). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code that would, individually or in the aggregate, have a Material Adverse Effect. Each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification.

(uu) The Company believes the statistical and market and industry-related data prepared by Ovum to the extent included in the Pricing Prospectus to be reliable and accurate, and the written consent to the use of such data from Ovum, Inc. has been obtained.

(d) The information in the Prospectus under the caption “Selling Stockholders” (excluding percentages that appear in the table) that specifically relates to such Selling Stockholder (the “Selling Stockholder Information”) does not, and will not on Closing Date or the Additional Closing Date, if applicable, contain any untrue statement of a material fact or omit to state any 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.

(e) At any time prior to the Closing Date and the Additional Closing Date, if applicable, if there is any change in the information referred to in Section 6.2(e) hereof, such Selling Stockholder will immediately notify the Representatives of such change.

(g) Such Selling Stockholder has not taken and will not take, directly or indirectly, any action that constituted, or any action designed to, or that might reasonably be expected to cause or result in or constitute, under the Act or otherwise, stabilization or manipulation of the price of the Common Stock to facilitate the sale or resale of the Shares.

As used in this Section 6.2(i), the terms “delivery,” “securities account” and “security entitlement” have the meanings given them in Article 8 of the UCC.

8. Indemnification and Contribution.

(a) Subject to the limitations in this paragraph below, the Company agrees to indemnify and hold harmless you and each other Underwriter, the directors, officers, employees and agents of each Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses, including reasonable costs of investigation and attorneys’ fees and expenses (collectively, “Damages”) arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, in the Registration Statement, the Time of Sale Information, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or the Prospectus or in any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Preliminary Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or the Prospectus, but not in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, except to the extent that any such Damages arise out of or are based upon an untrue statement or omission or alleged untrue statement or omission that has been made therein or omitted therefrom in reliance upon and in conformity with the information furnished in writing to the Company by or on behalf of any Underwriter through you, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof, or by or on behalf of the Selling Stockholders, as the case may be, expressly for use in connection therewith or (ii) any inaccuracy in or breach of the representations and warranties of the Company contained herein or any failure of the Company to perform its obligations hereunder or under law; provided, however, that with respect to any untrue statement or omission made in any Preliminary Prospectus, the indemnity agreement contained in this paragraph shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter or to any officer, director, employee or agent of any Underwriter) from whom the person asserting any such Damages purchased the Shares concerned if both (A) a copy of the Time of Sale Information was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person as required by the Act and (B) the untrue statement or omission in the Preliminary Prospectus was corrected in the Time of Sale Information. This indemnification shall be in addition to any liability that the Company may otherwise have.

(b) Subject to the limitations in this Section 8, each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless (1) you and each other Underwriter, the directors, officers, employees and agents of each Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and (2) the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all Damages arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus or in the Registration Statement, the Time of Sale Information, any free writing prospectus, any Written Testing-the-Waters Communication or the Prospectus or in any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Preliminary Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or the Prospectus, but not in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Prospectus, Registration Statement, the Time of Sale Information, any free writing prospectus, any Written Testing-the-Waters Communication or the Prospectus or in any amendment or supplement thereto in reliance upon and in conformity with the Selling Stockholder Information, (ii) any inaccuracy in or breach of the representations and warranties of each Selling Stockholder contained herein or (iii) any failure of such Selling Stockholder to perform its obligations hereunder or under law. The Selling Stockholders shall not be required to provide indemnification under the first sentence of this Section 8(b) with respect to any untrue statement or omission made in any Preliminary Prospectus, if both (A) a copy of the Time of Sale Information was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person as required by the Act and (B) the untrue statement or omission in the Preliminary Prospectus was corrected in the Time of Sale Information. This indemnification shall be in addition to any liability that the Selling Stockholders or any Selling Stockholder may otherwise have. Notwithstanding the foregoing provisions or anything to the contrary in this Agreement, except in the event of fraud by a Selling Stockholder, the aggregate liability of any such Selling Stockholder pursuant to this subsection (b), the contribution provisions under subsection (e) and such Selling Stockholder’s representations and warranties contained herein and under any certificate delivered pursuant to this Agreement shall not exceed the net proceeds (after deducting underwriting discounts and commissions, but before expenses of such Selling Stockholder) received by such Selling Stockholder from the sale of the Shares sold by such Selling Stockholder hereunder (the “Net Proceeds”).

(c) In addition to their other obligations under this Section 8, each indemnifying party, severally and not jointly, agrees that, as an interim measure during the pendency of any claim, action, investigation, inquiry or other proceeding arising out of or based upon any statement or omission, or any inaccuracy in the applicable representations and warranties of the indemnifying party herein or failure to perform their respective obligations hereunder, all as set forth in this Section 8, the party against whom indemnification is being sought will reimburse each indemnified party on a monthly basis for all reasonable legal or other out-of-pocket expenses incurred in connection with investigating or defending any such claim, action, investigation, inquiry or other proceeding (to the extent documented by reasonably itemized invoices therefor), notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligation of the indemnifying party to reimburse each indemnified party for such expenses and the possibility that such payments might later be held to have been improper by a court of competent jurisdiction. To the extent that any such interim reimbursement payment is so held to have been improper, each indemnified party shall promptly return it to the person(s) from whom it was received. Any such interim reimbursement payments that are not made to the indemnified party within 30 days of a request for reimbursement shall bear interest compounded daily at a rate determined on the basis of the base lending rate announced from time to time by The Wall Street Journal from the date of such request. Notwithstanding the foregoing, it is understood and agreed that the Underwriters shall only be obligated to provide such interim reimbursement payments to the extent that the claim, action, investigation, inquiry or other proceeding pertains to alleged statements or omissions with respect to information furnished in writing by or on behalf of the Underwriters, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof.

(d) If any action or claim shall be brought against any Underwriter or any person controlling any Underwriter in respect of which indemnity may be sought jointly and severally against the Company and the Selling Stockholders, such Underwriter or such controlling person shall promptly notify in writing the party(s) against whom indemnification is being sought (the “indemnifying party” or “indemnifying parties”), and such indemnifying party(s) shall assume the defense thereof, including the employment of counsel reasonably acceptable to such Underwriter or such controlling person and the payment of all reasonable fees of and expenses incurred by such counsel. Such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action and participate in the defense thereof. In the event the Underwriter or any such controlling person employs separate counsel, the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person, unless (i) the indemnifying party(s) has (have) agreed in writing to pay such fees and expenses, (ii) the indemnifying party(s) has (have) failed to assume the defense and employ counsel reasonably acceptable to the Underwriter or such controlling person or (iii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such controlling person and the indemnifying party(s), and such Underwriter or such controlling person shall have been advised by its counsel that one or more legal defenses may be available to the Underwriter that may not be available to the Company or the Selling Stockholders, or that representation of such indemnified party and any indemnifying party(s) by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them. In the event that the conditions of clause (iii) of the preceding sentence are satisfied, the indemnifying party(s) shall not have the right to assume the defense of such action on behalf of such Underwriter or such controlling person, and the Company and the Selling Stockholders, as applicable, shall not be liable for the fees and expenses of more than one counsel for the Underwriters and such controlling persons. The indemnifying party(s) shall not be liable for any settlement of any such action effected without its (their several) written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, the indemnifying party(s) agree(s) to indemnify and hold harmless any Underwriter and any such controlling person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment, but in the case of a judgment only to the extent stated in Section 8(a) and Section 8(b).

(e) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company and the Selling Stockholders, their respective directors, their respective officers who sign the Registration Statement and any person who controls the Company or the Selling Stockholders within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing several indemnity from the Company and the Selling Stockholders to each Underwriter, but only with respect to information furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or any Preliminary Prospectus, or any amendment or supplement thereto; provided that it is understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof. If any action or claim shall be brought or asserted against the Company or the Selling Stockholders, any of their respective directors, any of their respective officers or any such controlling person based on the Registration Statement, the Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or any Preliminary Prospectus, or any amendment or supplement thereto, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph, such Underwriter shall have the rights and duties given to the Company and the Selling Stockholders by Section 8(d) (except that, if the Company and the Selling Stockholders shall have assumed the defense thereof, such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel employed by the Underwriter shall be at such Underwriter’s expense), and the Company and the Selling Stockholders, their respective directors, their respective officers and any such controlling persons, shall have the rights and duties given to the Underwriters by Section 8(d).

(f) In any event, 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 proceeding or threatened claim, action, suit or proceeding in respect of which the indemnification may be sought hereunder (whether or not the Representatives or any person who controls the indemnified party within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of such indemnified party and such indemnified party’s controlling persons from all liability arising out of such claim, action, suit or proceeding.

(g) If the indemnification provided for in this Section 8 is unavailable or insufficient for any reason whatsoever to an indemnified party in respect of any Damages referred to herein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Damages (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, from the offering and sale of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative and several fault of the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, in connection with the statements or omissions that resulted in such Damages as well as any other relevant equitable considerations. The relative and several benefits received by the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (after deducting underwriting discounts and commissions, but before deducting expenses) received by the Company and the Selling Stockholders, as applicable, 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; provided that, in the event that the Underwriters shall have purchased any Additional Shares hereunder, any determination of the relative benefits received by the Company and the Selling Stockholders or the Underwriters from the offering of the Shares shall include the net proceeds (after deducting underwriting discounts and commissions, but before deducting expenses) received by the Company and the Selling Stockholders, and the underwriting discounts and commissions received by the Underwriters, from the sale of such Additional Shares, in each case computed on the basis of the respective amounts set forth in the notes to the table on the cover page of the Prospectus. The relative fault of the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, 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 the Selling Stockholders, on the one hand, or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the provisions of this subsection (g), except in the event of fraud by a Selling Stockholder, such Selling Stockholder shall not be required to contribute any amount in excess of the amount by which (i) the Net Proceeds from the Shares sold by such Selling Stockholder pursuant to this Agreement exceeds (ii) the amount that such Selling Stockholder has been otherwise required to pay pursuant to subsection (b) above or otherwise as a result of such Selling Stockholder’s representations, warranties and indemnification obligations under this Agreement. Each Selling Stockholder’s obligations to contribute under this subsection (g) are several and not joint.

(h) The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 was determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to in Section 8(g). The amount paid or payable by an indemnified party as a result of the Damages referred to in Section 8(g) shall be deemed to include, subject to the limitations set forth above, 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 Section 8, no Underwriter shall be required to contribute any amount in excess of the amount of the underwriting commissions received by such underwriter in connection with the Shares underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to the respective numbers of Firm Shares set forth opposite their names in Schedule I hereto (or such numbers of Firm Shares increased as set forth in Section 10 hereof) and not joint.

(i) Notwithstanding Section 8(c), any Damages for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as Damages are incurred after receipt of reasonably itemized invoices therefor. The indemnity, contribution and reimbursement agreements contained in this Section 8 and the several, and not joint, representations and warranties of the Company and the Selling Stockholders 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, the Selling Stockholders, their respective directors or officers or any person controlling the Company or the Selling Stockholders, (ii) acceptance of any Shares and payment therefor hereunder and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to the Company or the Selling Stockholders, their respective directors or officers or any person controlling the Company or the Selling Stockholders, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

(n) At or prior to the Closing Date, you shall have received the written Lock-Up Agreements from each of the Company’s executive officers, directors and the Selling Stockholders.

(o) At or prior to the effective date of the Registration Statement, you shall have received a letter from the Corporate Financing Department of FINRA confirming that such Department has determined to raise no objections with respect to the fairness or reasonableness of the underwriting terms and arrangements of the offering contemplated hereby.

(p) You shall be satisfied that, and you shall have received a certificate dated the Additional Closing Date from each Selling Stockholder to the effect that, as of the Additional Closing Date: (i) the representations and warranties made by such Selling Stockholders herein are true and correct in all material respect on the Closing Date and (ii) such Selling Stockholder has complied with all obligations and satisfied all conditions that are required to be performed or satisfied on his or its part at or prior to the Additional Closing Date.

All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to you and your counsel.

The several obligations of the Underwriters to purchase Additional Shares hereunder are subject to the satisfaction on and as of the Additional Closing Date of the conditions set forth in this Section 9, except that, if the Additional Closing Date is other than the Closing Date, the certificates, opinions and letters referred to in this Section 9 shall be dated as of the Additional Closing Date and the opinions called for by paragraphs (c) and (h) shall be revised to reflect the sale of Additional Shares.

If any of the conditions hereinabove provided for in this Section 9 shall not have been satisfied when and as required by this Agreement, this Agreement may be terminated by you by notifying the Company of such termination in writing or by telegram at or prior to such Closing Date, but you shall be entitled to waive any of such conditions.

10. Effective Date of Agreement. This Agreement shall become effective upon the later of (a) the execution and delivery hereof by the parties hereto and (b) release of notification of the effectiveness of the Registration Statement by the Commission; provided, however, that the provisions of Sections 7 and 8 shall at all times be effective.

11. Defaulting Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase Firm Shares that it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Firm Shares, each non-defaulting Underwriter shall be obligated, severally, in the proportion in which the number of Firm Shares set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Shares set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in the Agreement Among Underwriters, to purchase the Firm Shares that such defaulting Underwriter or Underwriters agreed, but failed or refused to purchase. If any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case that does not result in termination of this Agreement, either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven (7) days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement.

12. Termination of Agreement. This Agreement shall be subject to termination in the absolute discretion of the Representatives, without liability on the part of any Underwriter to the Company by notice to the Company, if prior to the Closing Date or the Additional Closing Date (if different from the Closing Date and then only as to the Additional Shares), as the case may be, in your sole judgment, (i) trading in the Company’s Common Stock shall have been suspended by the Commission or the NASDAQ, (ii) trading in securities generally on the NYSE or NASDAQ shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by any such exchange or by order of the Commission or any court or other governmental authority, (iii) a general moratorium on commercial banking activities shall have been declared by either federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities or other international or domestic calamity, crisis or change in political, financial or economic conditions or other material event the effect of which on the financial markets of the United States is such as to make it, in your judgment, impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares. Notice of such cancellation shall be promptly given to the Company and its counsel by telegraph, telecopy or telephone and shall be subsequently confirmed by letter.

13. Failure of One or More of the Selling Stockholders to Sell and Deliver the Shares. 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 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 7 and 8 hereof, the Company or the Selling Stockholders or (ii) purchase the Shares that the Company and other Selling Stockholders have agreed to sell and deliver in accordance with the terms hereof. 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 pursuant to this Agreement at the Additional Closing Date, then the Underwriters shall have the right, by written notice from the Representatives to the Company and the Selling Stockholders, to postpone the Additional 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.

14. Information Furnished by the Underwriters. The Company acknowledges that (i) the list of Underwriters and their respective participation in the sale of Shares, (ii) the fourth paragraph, (iii) each paragraph under the sub-caption “Stabilization,” (iv) the paragraph under the sub-caption “Relationships,” and (v) the first paragraph under the sub-caption “Electronic Prospectus,” each under the caption “Underwriting” in the most recent Preliminary Prospectus and Prospectus, constitute the only information furnished by or on behalf of the Underwriters through you or on your behalf as such information is referred to in Sections 6.1(c), 6.1(d), 6.1(e), 6.1(f) and 8 hereof.

15. Miscellaneous. Except as otherwise provided in Sections 5 and 12 hereof, notice given pursuant to any of the provisions of this Agreement shall be in writing and shall be delivered

This Agreement has been and is made solely for the benefit of the several Underwriters, the Company and its directors and officers and the Selling Stockholders.

16. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without reference to choice of law principles thereunder. This Agreement may be signed in various counterparts, which together shall constitute one and the same instrument. This Agreement shall be effective when, but only when, at least one counterpart hereof shall have been executed on behalf of each party hereto. The Company, the Selling Stockholders and the Underwriters each hereby irrevocably waive any right they may have to a trial by jury in respect to any claim based upon or arising out of this Agreement or the transactions contemplated hereby.

17. Choice of Forum; Authorized Agent. The Company and each Selling Stockholder agrees that it, he or she will bring any suit, action, claim or proceeding arising out of or relating in any way to this Agreement, the Power of Attorney, the Custody Agreement, the Prospectus, the Registration Statement and/or the Offering exclusively in a state or federal court located in the Borough of Manhattan in the State of New York. The Company and each Selling Stockholder agrees to submit to and not challenge the personal jurisdiction of such court and irrevocably waives, to the fullest extent permitted by law, any objection which it, he or she may now or hereafter have to the laying of venue of any such suit, action, claim or proceeding brought in such a court, including but not limited to any argument that any such suit, action, claim or proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Selling Stockholder has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Selling Stockholder irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action, claim or proceeding.

Each Selling Stockholder hereby irrevocably appoints Applied Optoelectronics, Inc., with offices at ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇., ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ (the “Authorized Agent”), as its agent for service of process in connection with any suit, action, claim or proceeding described in the preceding paragraph and agrees that service of process may be made upon such Selling Stockholder by overnight mail to the office of such agent. Each Selling Stockholder waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction or service of process with respect thereto. The Company agrees to serve as the Authorized Agent and act as each Selling Stockholder’s agent for service of process, and each Selling Stockholder agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect. Each Selling Stockholder agrees that service of process upon its Authorized Agent shall be deemed, in every respect, effective service of process upon such Selling Stockholder.

18. No Fiduciary Duty. Notwithstanding any pre-existing relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by any of the Underwriters, the Company acknowledges and agrees that (i) nothing herein shall create a fiduciary or agency relationship between the Company, on the one hand, and the Underwriters, on the other hand; (ii) the Underwriters have been retained solely to act as underwriters and are not acting as advisors, experts or otherwise, to either the Company in connection with this offering, the 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; (iii) the relationship between the Company, on the one hand, and the Underwriters, on the other hand, is entirely and solely commercial, and the price of the Shares was established by the Company and the Underwriters based on discussions and arms’ length negotiations and the Company understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (iv) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (v) notwithstanding anything in this Agreement to the contrary, the Company acknowledges 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 Company for the shares and such interests may differ from the interests of the Company, and the Underwriters have no obligation to disclose, or account to the Company for any benefit they may derive from such additional financial interests. The Company hereby waives and releases, to the fullest extent permitted by the applicable law, any claims it may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company or any of its shareholders, managers, employees or creditors.

19. Research Analyst Independence. The Company and Selling Shareholders acknowledge that (a) 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 (b) the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company, the value of the Common Stock and/or the offering that differ from the views of their respective investment banking divisions. The Company and Selling Shareholders hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by the Underwriters’ independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company and/or Selling Shareholders by any Underwriter’s investment banking division. The Company and Selling Shareholders each acknowledge that each of the Underwriters is a full service securities firm and as such, from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that are the subject of the transactions contemplated by this Agreement.

▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

This letter is delivered to you pursuant to the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by Applied Optoelectronics, Inc. (the “Company”), as issuer, and ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Associates, Inc., and ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. as representatives (the “Representatives”) of the several underwriters named therein (the “Underwriters”). Upon the terms and subject to the conditions of the Underwriting Agreement, the Underwriters intend to effect a public offering of Common Stock of the Company (the “Shares”), as described in and contemplated by the registration statement of the Company on Form S-1 (the “Registration Statement”) to be filed with the Securities and Exchange Commission (the “Offering”).

The undersigned recognizes that it is in the best financial interests of the undersigned, as an officer or director, or an owner of stock, options, warrants or other securities of the Company (the “Company Securities”), that the Company complete the proposed Offering.

The undersigned further recognizes that the Company Securities held by the undersigned are, or may be, subject to certain restrictions on transferability, including those imposed by United States federal securities laws. Notwithstanding these restrictions, the undersigned has agreed to enter into this letter agreement to further assure the Underwriters that the Company Securities of the undersigned, now held or hereafter acquired, will not enter the public market at a time that might impair the underwriting effort.

EX A-2

Therefore, as an inducement to the Underwriters to execute the Underwriting Agreement, the undersigned hereby acknowledges and agrees that the undersigned will not (and will cause any spouse, domestic partner, parent, child or grandchild (each, an “immediate family member”) or immediate family member of the spouse living in the undersigned’s household, any partnership, corporation or other entity within the undersigned’s control, and any trustee of any trust that holds Company Securities for the benefit of the undersigned or such spouse or immediate family member not to) (i) offer, sell, contract to sell, pledge, grant any option to purchase, contract to purchase or purchase any option or contract to sell, grant any option, right or warrant, lend, make any short sale or otherwise transfer or dispose of, directly or indirectly (collectively, a “Disposition”), any Company Securities, or any securities convertible into or exercisable or exchangeable for, or any rights to purchase or otherwise acquire, any Company Securities held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned pursuant to the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (collectively, the “Lock-Up Shares”), for a period commencing on the date hereof and ending 90 days after the date of the Company’s prospectus first filed pursuant to Rule 424(b) under the Act with respect to the Offering, inclusive (the “Lock-Up Period”), without, in each case, the prior written consent of each of the Representatives or (ii) exercise or seek to exercise or effectuate in any manner any rights of any nature that the undersigned has or may have hereafter to require the Company to register under the Act the undersigned’s sale, transfer or other disposition of any of the Lock-Up Shares or other securities of the Company held by the undersigned, or to otherwise participate as a selling securityholder in any manner in any registration effected by the Company under the Act, excluding under the Registration Statement, during the Lock-Up Period. Notwithstanding the foregoing, if during any period that the Company is not an “emerging growth company” (as such term is defined in Section 2(a) of the Act) and (x) during the last 17 days of the Lock-Up Period, the Company issues a release concerning earnings or material news or a material event relating to the Company occurs, or (y) prior to the expiration of the Lock-Up Period, the Company announces it will release earnings results during the 16 day period beginning on the last day of the Lock-Up Period, then the restrictions imposed in this letter agreement shall continue to apply until the expiration of the 18 day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging, collar (whether or not for any consideration) or other transaction that is designed to or reasonably expected to lead or result in a Disposition of Lock-Up Shares during the Lock-Up Period, even if such Lock-Up Shares would be disposed of by someone other than such holder. Such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call option or reversal or cancellation thereof) with respect to any Lock-Up Shares 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 Lock-Up Shares. Further, notwithstanding the restrictions herein, the undersigned may enter into a written trading plan designed to comply with Rule 10b5-1(c) of the Exchange Act; provided, however, that no sales or other dispositions may occur under such plans during the Lock-Up Period (as may have been extended).

The undersigned hereby acknowledges and agrees that written notice of any extension of the Lock-Up Period pursuant to the previous paragraph will be delivered by the Company to the Representatives in accordance with the Underwriting Agreement and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned and the Representatives agree that proper written notice may be delivered by the Company by filing a Form 8-K disclosing an extension of the initial Lock-Up Period. Unless the Company has filed a Form 8-K disclosing that the Lock-Up Period (as may have been extended) has expired, the undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this letter agreement during the period from the date of this agreement to and including the 34^th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Representatives and will not consummate such transaction or take any such action unless it has received written confirmation from the Representatives that the Lock-Up Period (as may have been extended) has expired.

EX A-3

Notwithstanding the agreement not to make any Disposition during the Lock-Up Period (as may be extended), you have agreed that the foregoing restrictions shall not apply to:

(1)

the Company Securities being offered in the prospectus included in the Registration Statement;

(2)

any grant or exercise of options pursuant to the Company’s existing stock option plans;

(3)

any Disposition of Company Securities as a bona fide gift or gifts; or

(4)

any Disposition of Company Securities to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned;

provided, however, that any Disposition described in clauses (2), (3) or (4) above shall be permitted only if (a) each resulting recipient or transferee of Company Securities executes and delivers to the Representatives an agreement satisfactory to the Representatives, certifying that such recipient or transferee is bound by the terms of this agreement and has been in compliance with the terms hereof since the date first above written as if it had been an original party hereto, (b) to the extent any interest in the Company Securities is retained by the undersigned or an immediate family member living in the undersigned’s household, such securities shall remain subject to the restrictions contained in this agreement, (c) no filing under the Exchange Act shall be required or shall be voluntarily made during the Lock-Up Period (as may be extended), and (d) no party (including transferor, transferee, donor or recipient) shall be required by law (including without limitation the disclosure requirements of the Exchange Act) to make, and each such party shall agree not to voluntarily make, any public announcement of the Disposition (other than a filing on a Form 5, Schedule 13D or Schedule 13G (or 13D/A or 13G/A) made after the expiration of the Lock-Up Period (as may be extended)).

The undersigned now has, and, except as contemplated by clause (1), (2), (3) or (4) above, for the duration of this letter agreement will have, good and marketable title to the undersigned’s Company Securities or securities convertible into or exercisable or exchangeable for the undersigned’s Company Securities, free and clear of all liens, encumbrances, and claims whatsoever.

The undersigned agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Shares, except in compliance with the foregoing restrictions. In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of Lock-Up Shares if such transfer would constitute a violation or breach of this letter.

It is understood that the undersigned will automatically be released from the obligations under this letter agreement if (a) the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, or (b) the Company advises the Representatives in writing prior to the execution of the Underwriting Agreement that it has determined not to proceed with the Offering.

This letter shall be binding on the undersigned and the respective successors, heirs, personal representatives and assigns of the undersigned. Capitalized terms used but not defined herein have the respective meanings assigned to such terms in the Underwriting Agreement.
