2. Representations and Warranties of the Company and Selling Stockholders Regarding the Offering.

(a) The Company represents and warrants to, and agrees with, the several Underwriters, as of the date hereof and as of the Closing Date (as defined in Section 4(c) below), except as otherwise indicated, as follows:

(i) At each applicable time of effectiveness, at the date hereof and at the Closing Date, the Registration Statement, the S-8 Registration Statement and any post-effective amendments thereto conformed or will conform in all material respects with the requirements of the Securities Act and the Rules and Regulations and did not or 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 Time of Sale Disclosure Package (as defined in Section 2(a)(iii) below) as of the date hereof and at the Closing Date, and the Final Prospectus, as amended or supplemented, at the time of filing pursuant to Rule 424(b) under the Securities Act and at the Closing Date, 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, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the two immediately preceding sentences shall not apply to statements in or omissions from the Registration Statement, the S-8 Registration Statement, the Base Prospectus, the Preliminary Prospectus Supplement, the Final Prospectus Supplement, the Final Prospectus or 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 use in the preparation thereof. The Registration Statement and S-8 Registration Statement contain all exhibits and schedules required to be filed by the Securities Act or the Rules and Regulations.

Any further documents so filed and incorporated by reference in the Registration Statement, the S-8 Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act, and will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The representations and warranties set forth in the immediately preceding sentence shall not apply to statements in or omissions from any Issuer Free Writing 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 use in the preparation thereof.

Neither the filing of the Registration Statement, the S-8 Registration Statement nor the offering or sale of the Shares as contemplated by this Agreement gives rise to any rights for or relating to the registration of any shares of Common Stock or other securities of the Company, other than such rights that have been waived.

4. Purchase, Sale and Delivery of Shares.

(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 the Firm Shares to the Underwriters and (ii) each Selling Stockholder agrees, severally and not jointly, to sell to the Underwriters the number of Selling Stockholder Shares set forth opposite such Selling Stockholder’s name on Schedule II hereto. The Underwriters agree, severally and not jointly, to (i) purchase from the Company the respective numbers of the Firm Shares set forth opposite the names of the Underwriters in Schedule I hereto and (ii) purchase from each Selling Stockholder the number of Selling Stockholder Shares (to be adjusted by the Representatives so as to eliminate fractional shares) determined by multiplying the aggregate number of Selling Stockholder Shares to be sold by such Selling Stockholder by a fraction, the numerator of which is the aggregate number of Firm Shares to be purchased by such Underwriter and the denominator of which is the aggregate number of Firm Shares to be purchased by all of the Underwriters from the Company. The purchase price to be paid by the Underwriters to the Company for the Firm Shares and to the Selling Stockholders for the Selling Stockholder Shares shall be $1.598 per share (the “Per Share Price”).

(b) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company hereby grants to the Underwriters an option to purchase some or all of the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, all or any portion of the Additional Shares at the price per share equal to the Per Share Price, as may be necessary to cover over-allotments made in connection with the transactions contemplated hereby. The number of Additional Shares to be purchased by each Underwriter shall be the same percentage

(as adjusted by the Representatives to eliminate fractions) of the total number of Additional Shares to be purchased by the Underwriters as such Underwriter is purchasing of the Firm Shares. This option may be exercised by the Representatives at any time (but not more than once) on or before the thirtieth (30th) day following the date hereof, upon written notice from the Representatives to the Company (the “Option Notice”). The Option 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, unless the Company and the Representatives otherwise agree, the Option Closing Date shall not be earlier than the Closing Date (as defined below) with respect to the Firm Shares, nor earlier than the first business day after the date on which the option shall have been exercised, nor later than the fifth business day after the date on which the option shall have been exercised.

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

(c) The Shares will be delivered by the Company and the Selling Stockholders, as applicable, to or as instructed by the Representatives for the respective accounts of the several Underwriters against payment of the purchase price therefor by wire transfer of same day funds to the accounts specified by the Company and the Selling Stockholders, or such other location as may be mutually acceptable, at 7:00 a.m. pacific standard time, on the third (or if the Shares are priced, as contemplated by Rule 15c6-1(c) under the Exchange Act, after 4:30 p.m. Eastern time, the fourth) business day following the date hereof, or at such other time and date as the Representatives, the Company and the Selling Stockholders determine pursuant to Rule 15c6-1(a) under the Exchange Act, or, in the case of the Additional Shares, at such date and time set forth in the Option Notice. The time and date of delivery of the Firm Shares and the Selling Stockholders Shares, or the Additional Shares, as applicable, is referred to herein as the “Closing Date.” Delivery of the Shares shall be made by credit through full fast transfer to the accounts at The Depository Trust Company designated by the Representatives.

5. Covenants and Other Agreements.

(a) The Company covenants and agrees with the Underwriters as follows:

(i) During the period beginning on the date hereof and ending on the later of the Closing Date or such date, as reasonably determined by the Representatives, the Prospectus is no longer required by law to be delivered in connection with sales by an underwriter or dealer (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, the S-8 Registration Statement, the Time of Sale Disclosure Package or the Prospectus, the Company shall furnish to the Representatives for review and comment a copy of each such proposed amendment or supplement, and the Company shall not file any such proposed amendment or supplement to which any Representative reasonably objects.

(ii) From the date of this Agreement until the end of the Prospectus Delivery Period, the Company shall promptly advise the Representatives in writing (A)

of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (B) of the time and date of any filing of any post-effective amendment to the Registration Statement, the S-8 Registration Statement, or any amendment or supplement to the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, (C) of the time and date that any post-effective amendment to the Registration Statement or the S-8 Registration Statement becomes effective and (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the S-8 Registration Statement or of any order preventing or suspending their use or the use of 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 during the Prospectus Delivery Period, 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 164(b) of the Securities Act).

(iii) (A) During the Prospectus Delivery Period, the Company will comply 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, as now and hereafter amended, so far as necessary to permit the continuance of sales of or dealings in the Shares as contemplated by the provisions hereof, the Time of Sale Disclosure Package, the Registration Statement, the S-8 Registration Statement and the Prospectus. If during such period any event occurs the result of which would cause the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) to 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 Representatives or their counsel to amend the Registration Statement or the S-8 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 that 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 following the time it becomes aware of such opinion, notify the Representatives and amend the Registration Statement or the S-8 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) During the Prospectus Delivery Period, if at any time following the 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 S-8 Registration Statement or any Prospectus or included or would include, when taken together with the Time of Sale Disclosure Package 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 will promptly notify the Representatives and 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 Shares for sale under the securities laws of such jurisdictions as the Representatives reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Shares, except that the Company shall not be required in connection therewith to (A) qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified, (B) to execute a general consent to service of process in any state, or (C) to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject.

(v) The Company will furnish to the Representatives and counsel for the Representatives copies of the Registration Statement, the S-8 Registration Statement, each Prospectus, any Issuer Free Writing Prospectus, and all amendments and supplements to such documents, in each case promptly after they become available and in such quantities as any Representative 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 will pay or cause to be paid: (A) all expenses (including transfer taxes allocated to the respective transferees) incurred by the Company in connection with the delivery to the Underwriters of the Shares, (B) all expenses and fees incurred by the Company (including, without limitation, fees and expenses of the Company’s counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement or the S-8 Registration Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Shares, the Time of Sale Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and any amendment thereof or supplement thereto, (C) all reasonable filing fees and reasonable fees and disbursements of the Representatives’ counsel incurred in connection with the qualification of the Shares for offering and sale by the Underwriters or by dealers under FINRA rules or under the securities or blue sky laws of the states and other jurisdictions that the Representatives shall reasonably request, (D) the fees and expenses of any transfer agent or registrar of the Shares, (E) NYSE MKT listing fees, if any, and (F) all other costs and expenses incident to the performance of its obligations hereunder that are not otherwise specifically provided for herein. In addition to the

foregoing, on the initial Closing Date the Company will reimburse the Representatives up to $100,000 for fees, costs, disbursements and out-of-pocket expenses incurred by the Representatives, including fees and costs of Representatives’ counsel, in connection with the transactions contemplated hereby. If this Agreement is terminated by the Representatives in accordance with the provisions of Section 6 or Section 9, the Company will reimburse the Underwriters for all out-of-pocket disbursements (including, but not limited to, reasonable fees and disbursements of counsel, travel expenses, postage, facsimile and telephone charges) incurred by the Underwriters in connection with their investigation, preparing to market and marketing the Shares or in contemplation of performing its obligations hereunder.

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

(ix) The Company has not taken and will not take, directly or indirectly, during the Prospectus Delivery Period, any action designed to or which might reasonably be expected to cause or result in, or that has constituted, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares.

(x) The Company hereby agrees that, without the prior written consent of the Representatives, it will not, during the period ending ninety (90) days after the date hereof (“Lock-Up Period”), (A) offer, pledge, issue, sell, contract to sell, purchase, contract to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock; or (B) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (A) or (B) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (C) file any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock. The restrictions contained in the preceding sentence shall not apply to (1) the Shares to be sold hereunder, (2) the issuance of Common Stock upon the exercise of options or warrants disclosed as outstanding in the Registration Statement (excluding exhibits thereto) or the Prospectus and the vesting of restricted stock awards or units, (3) the issuance of employee stock options not exercisable during the Lock-Up Period and the grant, redemption or forfeiture of restricted stock awards or restricted stock units pursuant to equity incentive plans described in the Registration Statement (excluding exhibits thereto) or as new employee inducement grants, or (4) the issuance of Common Stock or warrants to purchase Common Stock in connection with mergers or acquisitions of securities, businesses, property or other assets, joint ventures, strategic alliances, equipment leasing arrangements or debt financing. Notwithstanding the foregoing, if (x) the Company issues an earnings release or material news, or a material event relating to the Company occurs, during the last 17 days of the Lock-Up Period, or (y) 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, the restrictions imposed by this clause 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, unless the Representatives waive such extension in writing.

(b) The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, it will not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of the free writing prospectus included in Schedule III. Any such free writing prospectus consented to by the Representatives 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 or will comply with the requirements of Rule 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record-keeping.

(c) The Representatives covenant and agree that the Representatives will pay or cause to be paid all expenses incurred by the Selling Stockholders in connection with the transactions contemplated hereby in an amount equal to $28,764; provided, however, that if this Agreement is terminated by the Representatives in accordance with the provisions of Section 6 or Section 9, the Representatives shall have no obligation to pay such expenses to the Selling Stockholders.

of such Underwriter specifically for use in the preparation thereof, and will reimburse the Selling Stockholders and Company for any legal or other expenses reasonably incurred by the Selling Stockholders and the Company in connection with evaluating, investigating or defending against any such loss, claim, damage, liability or action.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) 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 failure 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 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof; provided, however, that if (i) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party; (ii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), or (iii) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, the indemnified party or parties shall have the right to employ a single counsel to represent it in any claim in respect of which indemnity may be sought under subsection (a), (b) or (c) of this Section 7, in which event the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party and reimbursed to the indemnified party or parties as incurred within 60 days after presenting a statement for the same to the Company; it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (plus local counsel).

The indemnifying party under this Section 7 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. 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 a party or could be named and indemnity was or would be sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes an unconditional release of such indemnified party from all liability for 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.

(e) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) 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), (b) or (c) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other 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 fault of the Company and the Selling Stockholders on the one hand and the Underwriters 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 and the Selling Stockholders on the one hand and the Underwriters 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 and the Selling Stockholders and 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 Final 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 Selling Stockholders or the Representatives by or on behalf of any Underwriter and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (e) were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the first sentence of this subsection (e). 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 (e) 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 that is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount of such Underwriter’s discount and commissions referenced in Section 4(a) actually received by such Underwriter pursuant to this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several and not joint, in proportion to their respective underwriting commitments pursuant to this Agreement.

(f) The obligations of the Company and the Selling Stockholders under this Section 7 shall be in addition to any liability that the Company and the Selling Stockholders may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and the obligations of each Underwriter under this Section 7 shall be in addition to any liability that such Underwriter may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to the Selling Stockholders and the Company, and officers, directors and each person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act.

(g) For purposes of this Agreement, the Representatives confirm, and the Company and the Selling Stockholders acknowledge, that there is no information concerning the Underwriters furnished in writing to the Company or the Selling Stockholders through the Representatives by or on behalf of any Underwriter specifically for preparation of or inclusion in the Registration Statement, The S-8 Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus, other than the statements set forth in the last paragraph on the cover page of the Prospectus, the marketing and legal names of each Underwriter, and the statements set forth in the “Underwriting” section of the Final Prospectus and Time of Sale Disclosure Package, only insofar as such statements relate to the amount of selling concession and re-allowance or to over-allotment, stabilization and related activities that may be undertaken by the Underwriters.

8. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements contained herein or in certificates delivered pursuant hereto, including, but not limited to, the agreements of the Underwriters, the Selling Stockholders and the Company contained in Section 5(a)(vii) and Section 5(c) and Section 7 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or the Selling Stockholders, the Company or any of their respective officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Shares to and by the Underwriters hereunder.

9. Termination of this Agreement.

(a) The Representatives 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) trading in the Company’s Common Stock shall have been suspended by the Commission or NYSE MKT or trading in securities generally on NYSE MKT, the New York Stock Exchange or the NASDAQ shall have been suspended, (ii) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE MKT, NASDAQ, or the New York Stock Exchange, by such exchange or by order of the Commission or any other governmental authority having jurisdiction, (iii) a banking moratorium shall have been declared by federal, New York or California state authorities, or (iv) there shall have occurred any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration by the United States of a national emergency or war, any substantial change in financial markets, any substantial change or development involving a prospective substantial change in United States or international political, financial or economic conditions or any other calamity or crisis, or (v) the Company suffers any loss by strike, fire, flood, earthquake, accident or other calamity, whether or not covered by insurance, that in the Representatives’ reasonable judgment is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Shares. Any such termination shall be without liability of any party to any other party except that the provisions of Section 5(a)(vii) and Section 7 hereof shall at all times be effective and shall survive such termination.

(b) If the Representatives elect to terminate this Agreement as provided in this Section, the Company shall be notified promptly by the Representatives by telephone, confirmed promptly thereafter by letter.

10. Default by One or More Underwriters.

(a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder, the Representatives may in their discretion arrange for another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six (36) hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of thirty-six (36) hours within which to procure another party or other parties reasonably satisfactory to the Representatives to purchase such Shares on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that the Representatives have so arranged for the purchase of such Shares, or the Company notifies the Representatives that the Company and the Selling Stockholders have so arranged for the purchase of such Shares, the Representatives or the Company shall have the right to postpone their purchase of the Shares for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, The S-8 Registration Statement, the Time of Disclosure Package or the Final Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the S-8 Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus which in the Representatives’ opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remain unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at the Closing Date, then the Company and the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at the Closing Date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares to be purchased at the Closing Date (other than by reason of any default on the part of the Company or the Selling Stockholders), or if the Company and the Selling Stockholders shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then the Company will have the right, by written notice given within the following 36-hour period to the Representatives, to terminate this Agreement.

11. 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 the Representatives, c/o Cowen and Company, LLS, ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and c/o Roth Capital Partners, LLC, ▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇ ▇▇▇▇▇, telecopy number: (▇▇▇) ▇▇▇-▇▇▇▇, Attention: Managing Director; and if to the Company, shall be mailed, delivered or telecopied to it at GigOptix, Inc., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, telecopy number: (▇▇▇) ▇▇▇-▇▇▇▇, Attention: Dr. ▇▇▇ ▇▇▇▇, with a copy (which shall not constitute notice) to ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇., ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, telecopy number: (▇▇▇) ▇▇▇-▇▇▇▇, Attention: ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇; or in each case to such other address as the person to be notified may have requested in writing. Any party to this Agreement may change such address for notices by sending to the parties to this Agreement written notice of a new address for such purpose.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the several Underwriters, the Company, the Selling Stockholders and their respective successors and assigns and, with respect to Section 7, the controlling persons, officers and directors referred to in Section 7. Nothing in this Agreement is intended or shall be construed to give to any other person, firm or corporation any legal or equitable remedy or claim under or in respect of this Agreement or any provision herein contained. The term “successors and assigns” as herein used shall not include any purchaser, as such purchaser, of any of the Shares from the Underwriters.

13. Absence of Fiduciary Relationship. The Company and the Selling Stockholders acknowledge and agree that: (a) each Underwriter has been retained solely to act as an underwriter in connection with the sale of the Shares and that no fiduciary, advisory or agency relationship between the Company or the Selling Stockholders and any Underwriter has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether any Underwriter has advised or is advising the Company or any Selling Stockholder on other matters; (b) the price and other terms of the Shares set forth in this Agreement were established by the Company and Selling Stockholders following discussions and arms-length negotiations with the Underwriters and the Company and Selling Stockholders are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (c) they have been advised that the Underwriters and their affiliates are engaged in a broad range of transactions that may involve interests that differ from those of the Company and the Selling Stockholders and that the Underwriters have no obligation to disclose such interest and transactions to the Company or the Selling Stockholders by virtue of any fiduciary, advisory or agency relationship; (d) they have been advised that each Underwriter is acting, in respect of the transactions contemplated by this Agreement, solely for the benefit of such Underwriter, and not on behalf of the Company or any Selling Stockholder.

14. Entire Agreement; Amendments and Waivers. This Agreement represents the entire agreement of the parties and supersedes all prior or contemporaneous written or oral agreements between them concerning the offer and sale of the Shares. No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the Company, the Representatives and the Selling Stockholders. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the

future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver be deemed or constitute a continuing waiver unless otherwise expressly provided.

15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph, clause or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph, clause or provision.

16. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California.

17. Authority of the Representatives. In connection with this Agreement, the Representatives will act for and on behalf of the several Underwriters, and any action taken under this Agreement by any Representative will be binding on all the Underwriters.

18. Counterparts. This Agreement may be executed and delivered (including by facsimile transmission and electronic mail attaching a portable document file (.pdf)) in one or more counterparts and, if executed and delivered in more than one counterpart, the executed counterparts shall each be deemed to be an original and all such counterparts shall together constitute one and the same instrument.

Please sign and return to the Company the enclosed duplicates of this letter whereupon this letter will become a binding agreement between the Company, the Selling Stockholders and the several Underwriters in accordance with its terms.

As Representatives of the several

Underwriters to be named in the

within-mentioned Underwriting Agreement

Re:	GigOptix, Inc. (the “Company”)

Ladies and Gentlemen:

The undersigned is an officer or director of the Company and an owner of record or beneficially of certain shares of common stock of the Company, $0.001 par value per share (“Common Stock”), or securities convertible into, exchangeable, or exercisable for Common Stock (“Securities”). The Company proposes to enter into an underwriting agreement (the “Underwriting Agreement”) with you as Representatives of the underwriters, with respect to the public offering of Common Stock (the “Offering”). The undersigned acknowledges that the Offering will be of benefit to the undersigned. The undersigned also acknowledges that you and each underwriter to be named in the Underwriting Agreement will rely on the representations and agreements of the undersigned contained in this letter in connection with entering into the Underwriting Agreement and performing your and their obligations thereunder.

In consideration of the foregoing, the undersigned hereby agrees that the undersigned will not, without the Representatives’ prior written consent (which consent may be withheld in their sole discretion), directly or indirectly, sell, offer to sell, contract to sell, or grant any option for the sale (including without limitation any short sale), grant any security interest in, pledge, hypothecate, hedge, establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”) or otherwise dispose of or enter into any transaction which is designed to, or could be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise by the

- 37 -

Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company) (collectively, a “Disposition”) of any shares of Common Stock or any Securities currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Exchange Act) by the undersigned, or publicly announce the undersigned’s intention to do any of the foregoing (provided, however, that the undersigned may (i) complete one or more gift transfers of Securities to immediate family member(s) (as defined in Item 404(a) of Regulation S-K under the Exchange Act) who agree in writing to be similarly bound for the remainder of the Lock-up Period (as defined below); (ii) transfer Securities by will or the laws of descent and distribution or to one or more trusts for bona fide estate planning purposes, (iii) engage in transactions relating to the shares of Common Stock sold to the underwriter pursuant to the Underwriting Agreement, or (iv) transfer Securities to the Company or as may be required under any benefit plan of the Company, in each case without prior written consent and upon three (3) business days’ written notice to you), for a period commencing on the date of the Underwriting Agreement and continuing through the close of trading on the date sixty (60) days following the date of the Final Prospectus Supplement, as defined in the Underwriting Agreement, subject to adjustment as discussed below (the “Lock-up Period”). For the avoidance of doubt, nothing herein shall prevent the undersigned from, or restrict the ability of the undersigned to (a) purchase shares of Common Stock on the open market or under an employee stock purchase plan of the Company or (b) exercise any options or other convertible securities granted under any benefit plan of the Company.

The foregoing restrictions have been expressly agreed to preclude the holder of shares of Common Stock and/or the Securities from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a Disposition of shares of Common Stock or Securities during the Lock-up Period, even if such shares of Common Stock or Securities would be disposed of by someone other than such holder. Such prohibited hedging or other transactions would include, without limitation, any short sale (whether or not against the box) or any purchase, sale, or grant of any right (including, without limitation, any put or call option) with respect to any shares of Common Stock or Securities or with respect to any security (other than a broad-based market basket or index) that includes, relates to, or derives any significant part of its value from shares of Common Stock or Securities.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of shares of Common Stock or Securities held by the undersigned except in compliance with the foregoing restrictions.

Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Company releases earnings results or publicly announces other 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 in each case the Lock-Up Period will be extended until the expiration of the 18 day period beginning on the date of release of the earnings results or the public announcement regarding the material news or the occurrence of the material event, as applicable, unless you waive, in writing, such extension. The Representatives agree to waive such extension if the provisions of NASD Rule 2711(f)(4) or any applicable successor rule are not applicable to the Offering.

- 38 -

This agreement is irrevocable and will be binding on the undersigned and the respective successors, heirs, personal representatives, and assigns of the undersigned.

Nothing in this Lock-up Agreement shall constitute an obligation to purchase shares of Common Stock or Securities of the Company. If the Underwriting Agreement does not become effective by September 30, 2015, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to the payment for and delivery of the Common Stock to be sold thereunder, the undersigned shall be released from all obligations under this Lock-up Agreement.

This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
