Such registration statement has been declared effective by the Commission. Such registration statement, at any given time, including amendments thereto at such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at such time and the documents and information otherwise deemed to be a part thereof or included therein by Rule 430B under the Securities Act or otherwise pursuant to the Rules and Regulations at such time, is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.”

The Company proposes to file with the Commission pursuant to Rule 424 under the Securities Act a final prospectus supplement relating to the Securities to a form of prospectus included in the Registration Statement relating to the Securities in the form heretofore delivered to the Underwriters. Such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus.” Such supplemental form of prospectus, in the form in which it shall be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus.” Any preliminary form of Prospectus which is filed or used prior to filing of the Prospectus is hereinafter called a “Preliminary Prospectus.” Any reference herein to the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the date of such prospectus.

For purposes of this Agreement, all references to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”). All references in this Agreement to amendments or supplements to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to mean and include the subsequent filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is deemed to be incorporated by reference therein or otherwise deemed by the Rules and Regulations to be a part thereof.

(a) The Company represents and warrants to, and agrees with, the Underwriters as follows:

(i) No order preventing or suspending the use of the Registration Statement (including any post-effective amendment thereto), any Preliminary Prospectus or the Prospectus has been issued by the Commission and each such document, at the time of filing or the time of first use within the meaning of the Rules and Regulations, in each case as applicable, complied in all material respects with the requirements of the Securities Act and the Rules and Regulations and 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; except that the foregoing shall not apply to statements in or omissions from the Registration Statement (including any post-effective amendment thereto), any Preliminary Prospectus or the Prospectus made in reliance upon, and in conformity with, written information furnished to the Company by the Representative specifically for use in the preparation thereof.

(ii) To the Company’s knowledge, the Company has complied to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information, if any. The Registration Statement has been declared effective by the Commission’s staff and remains effective as provided in Section 8 of the Securities Act. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, are contemplated or threatened by the Commission.

(iii) Each part of the Registration Statement and any post-effective amendment thereto, at the time such part became effective (including each deemed effective date with respect to the Underwriters pursuant to Rule 430B under the Securities Act), at all other subsequent times until the expiration of the Prospectus Delivery Period (as defined below), and at the Closing Date (as hereinafter defined), and the Prospectus (or any amendment or supplement to the Prospectus), at the time of filing or the time of first use within the meaning of the Rules and Regulations, at all subsequent times until expiration of the Prospectus Delivery Period, and at the Closing Date complied and will comply, in each case in all material respects, with the applicable requirements and provisions of the Securities Act, the Rules and Regulations and the Exchange 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.

The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement and the Prospectus fairly presents the information called for in all material respects and is prepared in accordance with the rules and regulations of the Commission applicable thereto. The representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with written information relating to the Underwriters furnished to the Company by the Representative, specifically for use in the preparation thereof.

The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein.

(B) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Securities Act) of the Securities and (2) at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405 under the Securities Act, including the Company or any subsidiary in the preceding three years not having been convicted of a felony or misdemeanor or having been made the subject of a judicial or administrative decree or order as described in Rule 405 (without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an ineligible issuer), nor an “excluded issuer” as defined in Rule 164 under the Securities Act.

(xxxvii) Nothing has come to the attention of the Company that has caused it to believe that the statistical and market-related data included in the Registration Statement, the Pricing Disclosure Package, and the Prospectus is not based on or derived from sources that are reliable.

(b) Any certificate signed by any officer of the Company and delivered to the Underwriters or to the Underwriters’ Counsel shall be deemed a representation and warranty by the Company to the Underwriters as to the matters covered thereby.

(a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, (i) the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at a purchase price equal to $1.288 per share or such higher price so that the underwriting discount, following the offering of the shares and the price to the public as contemplated by the Prospectus, with respect to each such share is 8% (the “Per Share Price”), the Firm Shares as set forth opposite the name of such Underwriter on Schedule VI hereto and (ii) in the event and to the extent that the Underwriters shall exercise the election to purchase Additional Shares as provided below, the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the purchase price per share set forth in clause (a)(i) of this Section 3, that

portion of the number of Additional Shares as to which such election shall have been exercised (to be adjusted so as to eliminate fractional shares) determined by multiplying such number of Additional Shares by a fraction, the numerator of which is the maximum number of Additional Shares which such Underwriter is entitled to purchase as set forth opposite the name of such Underwriter in Schedule VI hereto and the denominator of which is the maximum number of Additional Shares that all of the Underwriters are entitled to purchase hereunder.

As referenced in Section 3(a)(ii) above, the Company hereby grants to the several Underwriters the option to purchase from the Company an aggregate of up to fifteen percent (15%) Additional Shares, at the Per Share Price. This option may be exercised by the Representative on behalf of the Underwriters at any time (but not more than once) on or before the date that is forty five (45) days following the date hereof, by written notice to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised, and the date and time when the Additional Shares are to be delivered (such date and time being herein referred to as the “Option Closing Date”); provided, however, that the Option Closing Date shall not be earlier than the Closing Date nor later than one business day after the date on which the option shall have been exercised unless the Company and the Underwriters otherwise agree.

Payment of the purchase price and delivery for the Additional Shares shall be made at the Option Closing Date in the same manner and at the same office as the payment for the Firm Shares as set forth in subparagraph (b) below.

(b) The Firm Shares will be delivered by the Company to the Underwriters for the Underwriters’ accounts against payment of the purchase price therefor by wire transfer of same day funds payable to the order of the Company, as appropriate, at the offices of National Securities Corporation, 410 Park Avenue, 14^th Floor, New York, NY 10022, or such other location as may be mutually acceptable, (1) with respect to the Firm Shares, at 8:00 a.m. Pacific time on the third (or if the Firm Shares are priced, as contemplated by Rule 15c6-1(c) under the Exchange Act, after 4:30 p.m. Eastern time, the fourth) full business day following the date hereof, or at such other time and date as the Representative and the Company determine pursuant to Rule 15c6-1(a) under the Exchange Act (such time and date of delivery being herein referred to as the “Closing Date”) and (2) with respect to the Additional Shares, at 8:00 a.m. Pacific time on the Option Closing Date. If the Representative so elects, delivery of the Securities may be made by credit through full fast transfer to the account at The Depository Trust Company designated by the Representative. Certificates representing the Securities, in definitive form and in such denominations and registered in such names as the Representative may request upon at least two business days’ prior notice to the Company, will be made available for checking and packaging not later than 10:30 a.m., Pacific time, on the business day next preceding the applicable closing date at the offices of National Securities Corporation, 410 Park Avenue, 14^th Floor, New York, NY 10022, or such other location as may be mutually acceptable.

(i) During the period beginning on the date hereof and ending on the later of the Closing Date (or the Option Closing Date, if applicable) or such date, as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act is no longer required to be provided), in connection with sales by an underwriter or dealer (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, the Time of Sale Disclosure Package or the Prospectus, the Company shall furnish to the Underwriters for review a copy of each such proposed amendment or supplement, and the Company shall not file any such proposed amendment or supplement to which the Underwriters reasonably object in writing.

(ii) During the Prospectus Delivery Period, the Company shall promptly advise the Underwriters in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (ii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any Preliminary Prospectus, the Time of Sale Disclosure Package or the Prospectus, (iii) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or of any order preventing or suspending its use or the use of any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Common Stock from any securities exchange upon which it is listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at any time, the Company will use its reasonable efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b), 430A and 430B, as applicable, under the Securities Act and will use its reasonable efforts to confirm that any filings made by the Company under Rule 424(b) or Rule 433 were received in a timely manner by the Commission (without reliance on Rule 424(b)(8) or Rule 164(b)).

(iii) (A) During the Prospectus Delivery Period, the Company will comply as far as it is able with all requirements imposed upon it by the Securities Act, as now and hereafter amended, and by the Rules and Regulations, as from time to time in force, and by the Exchange Act so far as necessary to permit the continuance of sales of or dealings in the Securities as contemplated by the provisions hereof, the Time of Sale Disclosure Package, and the Registration Statement and the Prospectus. If during such period any event occurs as a result of which the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package ) would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary or appropriate in the opinion of the Company or its counsel or the Underwriters or counsel to the Underwriters to amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) to comply with the

Securities Act or to file under the Exchange Act any document which would be deemed to be incorporated by reference in the Prospectus in order to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Underwriters and will amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) or file such document (at the expense of the Company) so as to correct such statement or omission or effect such compliance.

(B) If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the Statutory Prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company has promptly notified or promptly will notify the Underwriters and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(iv) The Company shall take or cause to be taken all necessary action to qualify the Securities for sale under the securities laws of such jurisdictions as the Underwriters reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or as a dealer in securities in any state in which it is not so qualified or to execute a general consent to service of process in any state or to subject itself to taxation in respect of doing business in any state in which it is not otherwise required to be so subject.

(v) The Company will furnish to the Underwriters and counsel for the Underwriters, without charge, copies of the Registration Statement, each Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus, and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Underwriters may from time to time reasonably request.

(vi) The Company will make generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period that shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations.

(vii) The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay or cause to be paid (A) all expenses (including transfer taxes allocated to the respective transferees) incurred in connection with the delivery to the Underwriters of the Securities, (B) all expenses and fees of the Company in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Securities, each Preliminary

Prospectus, the Prospectus, any Issuer Free Writing Prospectus and any amendment thereof or supplement thereto, and the printing, delivery, and shipping of this Agreement and other underwriting documents, including Blue Sky Memoranda (covering the states and other applicable jurisdictions), (C) all filing fees in connection with the qualification of the Securities for offering and sale by the Underwriters or by dealers under the securities or blue sky laws of the states and other jurisdictions which the Underwriters shall designate, (D) the fees and expenses of any transfer agent or registrar, (E) the filing fees incident to any required review and approval by the Financial Industry Regulatory Authority (“FINRA”) of the terms of the sale of the Securities, (F) listing fees, if any, (G) all fees, disbursements and expenses (including but not limited to fees disbursements of the Representative’s counsel) incurred by the Underwriters in connection with the sale of the Securities provided for herein, and (G) all other costs and expenses incident to the performance of its obligations hereunder that are not otherwise specifically provided for herein; provided, however, that the maximum amount that shall be reimbursed to the Underwriters by the Company under this Section 4(a)(vii), including legal expenses, shall be $60,000, which shall be payable at the closing of the sale of the Firm Shares or otherwise pursuant to this Section 4(a)(vii). If this Agreement is terminated by the Underwriters pursuant to Section 8 hereof or if the sale of the Securities provided for herein is not consummated for any reason (other than Underwriter’s bad faith, gross negligence or willful misconduct ) including any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company will reimburse the Underwriters for reasonable fees and disbursements of counsel not to exceed $60,000 in the aggregate (“Underwriters’ Counsel Fees”) and if the transactions contemplated hereunder are not consummated all other reasonable out-of-pocket disbursements (including but not limited to printing expenses, travel expenses, postage, facsimile and telephone charges) incurred by the Underwriters in connection with their investigation, preparing to market and marketing the Securities or in contemplation of performing their obligations hereunder within five (5) business days following the presentment to the Company of a written accounting related to the such fees and disbursements.

(viii) The Company will apply the net proceeds from the sale of the Securities to be sold by it hereunder for the purposes set forth in the Time of Sale Disclosure Package and in the Prospectus.

(ix) None of the Company and its subsidiaries has taken or will take and, to the Company’s knowledge, none of its or their employees, officers or directors has taken or will take, directly or indirectly, any action designed to or which might reasonably be expected to cause or result in, or which has constituted, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(x) Except as contemplated herein, the Company will not incur any liability for any finder’s or broker’s fee or agent’s commission in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby.

(xi) During the Prospectus Delivery Period, the Company will file on a timely basis with the Commission such periodic and current reports as are required by the Exchange Act and the rules and regulations promulgated thereunder.

(xii) The Company and its subsidiaries will maintain such controls and other procedures, including without limitation those applicable to the Company and required by Sections 302 and 906 of the Sarbanes-Oxley Act and the applicable regulations thereunder, that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, including without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive officer and its principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure, to ensure that material information relating to Company, including its subsidiaries, is made known to them by others within those entities.

(xiii) The Company and its subsidiaries will substantially comply with all effective applicable provisions of the Sarbanes-Oxley Act.

(xiv) The Company represents and agrees that, unless it obtains the prior written consent of the Representative, and the Underwriters represent and agree that, unless they obtain the prior written consent of the Company, they have not made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405 under the Securities Act, required to be filed with the Commission; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the free writing prospectuses included in Schedule II. Any such free writing prospectus consented to by the Company and the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

(xv) The Company will not, for a period of ninety (90) days from the date of the Prospectus (the “Lock-Up Period”), without the prior written consent of the Representative, directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, other than (A) the Company’s sale of the Securities hereunder, (B) the issuance of Common Stock or any equity awards (including the issuance of Common Stock upon exercise or settlement of such equity awards) pursuant to the Company’s employee benefit plans, stock option and employee stock purchase plans or other employee compensation plans as such plans are in existence

on the date hereof and described in the Prospectus or under any other equity compensation plan or agreement of the Company duly adopted for such purpose by a majority of the Company’s non-employee directors or a committee comprised of non-employee directors, (C) the issuance of Common Stock pursuant to the vesting or exercises of options, restricted stock units, warrants or rights outstanding on the date hereof and (D) the issuance by the Company of securities pursuant to acquisitions or strategic transactions (including issuances to vendors, customers, distributors or other commercial or strategic partners or potential commercial or strategic partners) approved by a majority of the Company’s disinterested directors, provided that such issuances are not primarily for the purpose of raising capital; provided, in the case of clauses (B) and (C), that if such shares of Common Stock are issued to a director or officer of the Company such issued shares will be covered by the lock-up agreements executed by such person. The Company will cause each director and executive officer listed on Schedule V to furnish to the Representative, prior to the Closing Date, a letter, substantially in the form of Schedule IV hereto, pursuant to which each such person shall agree, among other things, subject to the terms and conditions set forth in each such letter, not to directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, not to engage in any swap or other agreement or arrangement that transfers, in whole or in part, directly or indirectly, the economic risk of ownership of Common Stock or any such securities, during the period of ninety (90) days from the date of the Prospectus, without the prior written consent of the Representative. The Company also agrees that during such ninety (90) day period, the Company will not file any registration statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the Securities Act for any such transaction or which registers, or offers for sale, Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, except for registration statements on Form S-8 relating to employee benefit plans.

(xvi) On the Closing Date, the Company shall have complied in all material respects with the applicable requirements of the NASDAQ Capital Market for maintenance of inclusion of the Common Stock on the NASDAQ Capital Market, except where the failure to be in compliance would not reasonably be expected to result in delisting or any suspension of trading or other privileges.

(xvii) From the date hereof until the earlier of (i) a date thirty (30) days after the Closing Date and (ii) the Option Closing Date, the Company will not issue press releases, proposed communications with shareholders or other interested constituencies, or other public announcements or engage in any other publicity, without (i) providing the Representative and its counsel with copies of same and (ii) permitting the Representative and its counsel to comment thereon; provided, however, that ordinary and routine communications not related to the transactions contemplated hereunder or the financial position of the Company may be provided concurrently with their release.

5. CONDITIONS OF THE UNDERWRITERS’ OBLIGATIONS. The obligations of the Underwriters hereunder are subject to the accuracy, as of the date hereof and at each of the Closing Date and the Option Closing Date (as if made on the Closing Date or Option Closing Date, as applicable), of and compliance with all representations, warranties and agreements of the Company contained herein (except to the extent any such representations or warranties expressly relate to a specified earlier date, in which case, such representations and warranties shall be true and correct as of such specified earlier date), to the performance by the Company of its obligations hereunder and to the following additional conditions (except for any obligations or conditions that have been waived by the Representative in writing):

(a) If filing of the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, is required under the Securities Act or the Rules and Regulations, the Company shall have filed the Prospectus (or such amendment or supplement) or such Issuer Free Writing Prospectus with the Commission in the manner and within the time period so required (without reliance on Rule 424(b)(8)); the Registration Statement shall remain effective; no stop order suspending the effectiveness of the Registration Statement or any part thereof, or any amendment thereof, nor suspending or preventing the use of the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus shall have been issued; no proceedings for the issuance of such an order shall have been initiated or, to the Company’s knowledge, threatened; any request of the Commission for additional information (to be included in the Registration Statement, the Time of Sale Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or otherwise) shall have been complied with to the Underwriters’ reasonable satisfaction; and FINRA shall have raised no objection to the fairness and reasonableness of the underwriting terms and arrangements.

(b) The Underwriters shall not have advised the Company that the Registration Statement, the Time of Sale Disclosure Package or the Prospectus, or any amendment thereof or supplement thereto, or any Issuer Free Writing Prospectus, contains an untrue statement of fact which, in the Underwriters’ reasonable opinion, is material, or omits to state a fact which, in the Underwriters’ reasonable opinion, is material and is required to be stated therein or necessary to make the statements therein not misleading.

(c) Except as contemplated in the Time of Sale Disclosure Package and in the Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Disclosure Package, neither the Company nor any of its subsidiaries shall have incurred any liabilities or obligations, direct or contingent, which are material to the Company and its subsidiaries taken as a whole, or entered into any transactions not in the ordinary course of business which are material to the Company and its subsidiaries taken as a whole, or declared or paid any dividends or made any distribution of any kind with respect to its capital stock; and there shall not have been any change in the capital stock (other than a change in the number of outstanding shares of Common Stock due to the issuance of shares upon the exercise of outstanding options or warrants or upon the settlement of outstanding restricted stock units), or any material change in the short-term or long-term debt of the Company except for the extinguishment thereof, or any issuance of options, warrants, convertible securities or other rights to purchase the capital stock of the Company (other than issuances of equity compensation awards under equity compensation arrangements approved by the Board of Directors of the Company or committee thereof comprised entirely of independent directors) or any of the

Company’s subsidiaries, or any Material Adverse Change, or any loss by strike, fire, flood, earthquake, accident or other calamity, whether or not covered by insurance, incurred by the Company or any of the Company’s subsidiaries, the effect of which, in any such case described above, in the Representative’s judgment, makes it impractical or inadvisable to offer or deliver the Securities on the terms and in the manner contemplated in the Time of Sale Disclosure Package, the Registration Statement and in the Prospectus.

(d) On or after the Time of Sale (i) no downgrading shall have occurred in the rating accorded any of the Company’s securities by any “nationally recognized statistical organization,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s securities.

(e) On the Closing Date and the Option Closing Date, there shall have been furnished to the Underwriters the opinion of Morrison & Foerster LLP, counsel for the Company, dated the Closing Date and addressed to the Underwriters, in form and substance reasonably satisfactory to the Underwriters.

(f) On the date of the Prospectus at a time prior to the execution of this Agreement, on the effective date of any post-effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also at each of the Closing Date and the Option Closing Date, the Underwriters shall have received a letter of the Auditor (the “Comfort Letter”), dated the respective dates of delivery thereof, and addressed to the Underwriters, in form and substance satisfactory to the Underwriters.

(g) On each of the Closing Date and the Option Closing Date (if applicable), there shall have been furnished to the Underwriters a certificate, dated as of such closing date and addressed to the Underwriters, signed by the chief executive officer or the chief financial officer of the Company, to the effect that:

(i) The representations and warranties of the Company in this Agreement are true and correct, in all material respects, as if made at and as of the Closing Date or the Option Closing Date (as applicable) (except to the extent any such representations or warranties expressly relate to a specified earlier date, in which case, such representations and warranties shall be true and correct as of such specified earlier date), and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date or the Option Closing Date (as applicable) (except for any such agreements or conditions that have been waived by the Representative in writing);

(ii) No stop order or other order suspending the effectiveness of the Registration Statement or any part thereof or any amendment thereof or the qualification of the Securities for offering or sale nor suspending or preventing the use of the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, has been issued, and no proceeding for that purpose has been instituted or, to the Company’s knowledge, is contemplated or threatened by the Commission or any state or regulatory body; and

(iii) The signers of said certificate have carefully examined the Registration Statement, the Time of Sale Disclosure Package and the Prospectus, and any amendments thereof or supplements thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Time of Sale Disclosure Package, the Registration Statement or the Prospectus), and

(A) each part of the Registration Statement and the Prospectus, and any amendments thereof or supplements thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus) contain, and contained, when such part of the Registration Statement (or such amendment) became effective, all statements and information required to be included therein, each part of the Registration Statement, or any amendment thereof, does not contain, and did not contain, when such part of the Registration Statement (or such amendment) became effective, any untrue statement of a material fact or omit to state, and did not omit to state when such part of the Registration Statement (or such amendment) became effective, any material fact required to be stated therein or necessary to make the statements therein not misleading, and the Prospectus, as amended or supplemented, does not include and did not include as of its date, or the time of first use within the meaning of the Rules and Regulations, any untrue statement of a material fact or omit to state and did not omit to state as of its date, or the time of first use within the meaning of the Rules and Regulations, a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading,

(B) neither (1) the Time of Sale Disclosure Package nor (2) any individual Issuer Limited-Use Free Writing Prospectus, when considered together with the Time of Sale Disclosure Package, include, nor included as of the Time of Sale any untrue statement of a material fact or omits, or omitted as of the Time of Sale, 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,

(C) since the Time of Sale, there has occurred no event required to be set forth in an amended or supplemented prospectus which has not been so set forth, and there has been no document required to be filed under the Exchange Act that upon such filing would be deemed to be incorporated by reference into the Time of Sale Disclosure Package, the Registration Statement or into the Prospectus that has not been so filed,

(D) subsequent to the respective dates as of which information is given in the Time of Sale Disclosure Package, neither the Company nor any of its subsidiaries has incurred any liabilities or obligations, direct or contingent, which are material to the Company and its subsidiaries taken as a whole, or entered into any transactions not in the ordinary course of business which are material to the Company and its subsidiaries taken as a whole, or declared or paid any dividends or made any distribution of any kind with respect to its capital stock, and except as disclosed in the Time of Sale Disclosure Package and in the Prospectus, there has not been any change in the capital stock (other

than a change in the number of outstanding shares of Common Stock due to the issuance of shares upon the exercise of outstanding options or warrants or upon the settlement of outstanding restricted stock units), or any material change in the short-term or long-term debt of the Company except for the extinguishment thereof, or any issuance of options, warrants, convertible securities or other rights to purchase the capital stock of the Company (other than issuances of equity compensation awards under equity compensation arrangements approved by the Board of Directors of the Company or committee thereof comprised entirely of independent directors) or any of its subsidiaries, or any Material Adverse Change, and

(E) except as stated in the Time of Sale Disclosure Package and in the Prospectus, there is not pending, or, to the knowledge of the Company, threatened or contemplated, any action, suit or proceeding to which the Company or any of its subsidiaries is a party before or by any court or governmental agency, authority or body, or any arbitrator, which would be reasonably expected to result in any Material Adverse Change.

(h) The Underwriters shall have received a letter from FINRA confirming that such has determined to raise no objections with respect to the fairness and reasonableness of the underwriting terms and arrangements of the offering contemplated hereby.

(i) The Company shall have furnished to the Underwriters and counsel for the Underwriters such additional documents, certificates and evidence as the Underwriters or counsel for the Underwriters may have reasonably requested.

(j) The Underwriters shall have received the written agreements, substantially in the form of Schedule IV hereto, of the directors and executive officers of the Company listed on Schedule V to this Agreement.

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 the Underwriters and counsel for the Underwriters. The Company will furnish the Underwriters with such conformed copies of such opinions, certificates, letters and other documents as the Underwriters shall reasonably request.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, their respective officers, directors, employees and agents, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter may become subject, under the Securities Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be

incorporated by reference into the Prospectus), or 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, and will reimburse the Underwriters for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred (provided that any payment as expenses are incurred shall be reimbursed to the extent it is determined that the recipient was not entitled to payment of such expenses under this Agreement); or (ii) in whole or in part upon any inaccuracy in or breach of the representations and warranties of the Company contained herein; or (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for use in the preparation thereof.

In addition to their other obligations under this Section 6(a), the Company 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 alleged statement or omission, described in this Section 6(a), it will reimburse the Underwriters on a monthly basis for all reasonable legal fees or other expenses incurred in connection with investigating or defending any such claim, action, investigation, inquiry or other proceeding upon presentation of a written accounting in reasonable detail (but without the need to include the underlying statements or evidence of payment), notwithstanding the absence of a judicial determination as to the propriety and enforceability of the Company’s obligation to reimburse the Underwriters 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, the Underwriters shall promptly return it to the Company, together with interest, compounded daily, determined on the basis of the prime rate (or other commercial lending rate for borrowers of the highest credit standing) announced from time to time by Wells Fargo Bank, N.A. (the “Prime Rate”). Any such interim reimbursement payments which are not made to the Underwriters within 30 days of a request for reimbursement shall bear interest at the Prime Rate from the date of such request. This indemnity agreement shall be in addition to any liabilities which they may otherwise have.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus, or arise out of or are 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 Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by an Underwriter with respect to such Underwriter specifically for use in the preparation thereof, and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure. In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that if, in the reasonable opinion of counsel to the Underwriters, it would be inappropriate due to actual or potential differing interests between the Company and the Underwriters for the Company and the Underwriters to be represented by the same counsel, the Underwriters shall have the right to employ a single counsel to represent the Underwriters in any claim in respect of which indemnity may be sought by the Underwriters under subsection (a) of this Section 6, in which event the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the Underwriters as incurred (in accordance with the provisions of the second paragraph in subsection (a) above).

The indemnifying party under this Section 6 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party 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 this Section 6, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes

an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (b) 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.

(d) If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the respective Underwriter on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the respective Underwriter on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the respective Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the respective Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the respective Underwriter and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the respective Underwriter agree that it would not be just and equitable if contributions pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the respective Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities were offered to the public exceeds the amount of any damages that the respective Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to each person, if any, who controls the respective Underwriter within the meaning of the Securities Act; and the obligations of the respective Underwriter under this Section 6 shall be in addition to any liability that the respective Underwriter may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to each director of the Company (including any person who, with his

consent, is named in the Registration Statement as about to become a director of the Company), to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Securities Act.

(f) Each Underwriter confirms severally and not jointly and the Company acknowledges that there is no information concerning the Underwriters furnished in writing to the Company by the Underwriters specifically for inclusion in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, except for the following disclosure contained in the “Underwriting” section of the Prospectus: the first paragraph, the first sentence of the fourth paragraph, the tenth paragraph (subheading “Stabilization”), the eleventh paragraph (subheading “Electronic Offer, Sale and Distribution of Shares”) and the first sentence of the fourteenth paragraph (subheading “Offer Restrictions Outside the United States”) under the caption “Underwriting.”

7. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. All representations, warranties, and agreements of the Company herein or in certificates delivered pursuant hereto, including but not limited to the agreements of the Underwriters and the Company contained in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriters or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Securities to and by the Underwriters hereunder.

(a) The Underwriters shall have the right to terminate this Agreement by giving notice to the Company as hereinafter specified at any time at or prior to the Closing Date, if (i) the Company shall have failed, refused or been unable, at or prior to the Closing Date, to perform any material agreement on its part to be performed hereunder, (ii) any condition of the Underwriters’ obligations hereunder is not fulfilled or waived by the Representative in writing, (iii) trading in the Company’s Common Stock shall have been suspended by the Commission or the NASDAQ Capital Market or trading in securities generally on the NASDAQ Capital Market shall have been suspended, (iv) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NASDAQ Capital Market, by such Exchange or by order of the Commission or any other governmental authority having jurisdiction (which includes the Company’s Common Stock), (v) a banking moratorium shall have been declared by federal or state authorities which prevents payment by an Underwriter pursuant to Section 3, (vi) the Company is in material breach of any of its representations, warranties or covenants hereunder, (vii) the Underwriters shall have become aware after the date hereof, of events that are reasonably expected to result in (A) a Material Adverse Change, or (B) a material adverse change in general market conditions, in each case, as would make it impracticable, in the Underwriters’ reasonable judgement, to proceed with the offering, sale and/or delivery of the Securities or to enforce contracts made by the Underwriters for the sale of the Securities, or (viii) a director of the Company: (A) is charged with an indictable offence relating to any financial or corporate matter; (B) becomes the subject of a public action or investigation by a governmental body arising from conduct relating to the Company (or such governmental body announces that it intends to take any such action or undertake any such investigation); or (C) is enjoined, suspended or otherwise limited from serving as a director under the federal securities laws. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(a)(vii) and Section 6 hereof shall at all times be effective and shall survive such termination.

No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

10. NOTICES. Except as otherwise provided herein, all communications hereunder shall be in writing and, if to the Underwriters, shall be mailed, delivered or telecopied to National Securities Corporation, 410 Park Avenue, 14^th Floor, New York, NY 10022, fax: (212) 380-2828 Attention: Ivan Saval, e-mail: isaval@nationalsecuritiesib.com; if to the Company, shall be mailed, delivered or telecopied to it at Marrone Bio Innovations, Inc., 1540 Drew Avenue, Davis, CA 95617, Attention: General Counsel, e-mail: lmoore@marronebio.com; or in each case to such other address as the person to be notified may have requested in writing.

In order to induce National Securities Corporation (the “Underwriter”) to enter into an underwriting agreement with Marrone Bio Innovations, Inc., a Delaware corporation (the “Company”), with respect to the public offering (the “Offering”) of shares of the Company’s Common Stock, $0.00001 par value per share (“Common Stock”), the undersigned hereby agrees that for a period (the “lock-up period”) of ninety (90) days following the date of the final prospectus supplement filed by the Company with the Securities and Exchange Commission in connection with such Offering (the “Prospectus Supplement”), the undersigned will not, without the prior written consent of the Underwriter, directly or indirectly, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock (including, without limitation, shares of Common Stock or any such securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations promulgated under the Securities Exchange Act of 1934, as the same may be amended or supplemented from time to time (such shares or securities, the “Beneficially Owned Shares”)), (ii) enter into any swap, hedge or other agreement or arrangement that transfers, in whole or in part, the economic risk of ownership of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock, or (iii) engage in any short selling of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock. The foregoing sentence shall not apply to (a) transfers of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock as a bona fide gift, (b) in the case of a natural person, transfers of any Beneficially Owned Shares, Common Stock or securities convertible into or exercisable or exchangeable for Common Stock by will or intestate succession or to any trust, partnership corporation, limited liability company or other entity controlled by the undersigned for the direct or indirect benefit of the undersigned or any member of the immediate family of the undersigned, (c) distributions by a trust to its beneficiaries, (d) the distribution of shares of Common Stock to limited partners in the ordinary course of business of a fund owned or controlled by the undersigned, or (e) the entry into any plan under Rule 10b5-1 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”); provided that in the case of any transfer or distribution pursuant to clauses (a), (b) or (c), each donee or beneficiary, as applicable, shall agree to be bound by the terms of this Agreement, and in the case of clause (e), no sales shall be permitted to be made under such plan, and no public disclosure or filing under the Exchange Act by any party shall be required, or made voluntarily, in connection with the adoption of any such plan, prior to the expiration of the lock-up period.
