The Company has granted the Underwriters the option to purchase an aggregate of up to 416,250 additional shares of Common Stock (the “Additional Shares”) as may be necessary to cover over-allotments made in connection with the Offering. To the extent there are no additional Underwriters listed on Schedule I other than you, the term Representatives as used herein shall mean you, as Underwriters, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires.

As the Representative, you have advised the Company (a) that you are authorized to enter into this Agreement on behalf of the several Underwriters, and (b) that the several Underwriters are willing, acting severally and not jointly, to purchase the numbers of Underwritten Shares set forth opposite their respective names in Schedule I, plus their pro rata portion of the Additional Shares if you elect to exercise the over-allotment option in whole or in part for the accounts of the several Underwriters. The Underwritten Shares and Additional Shares are collectively referred to as the “Shares.”

The Company and the Underwriters hereby confirm their agreement as follows:

1. Registration Statement and Final Prospectus. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-199510) under the Securities Act of 1933, as amended (the “Securities Act”) and the rules and regulations (the “Rules and Regulations”) of the Commission thereunder, and such amendments to such registration statement (including post effective amendments) as may have been required to the date of this Agreement. Such registration statement, as amended (including any post effective amendments), has been declared effective by the Commission. Such registration statement, as amended (including post effective amendments thereto), the exhibits and any schedules thereto and the documents and information otherwise incorporated by reference therein, deemed to be a part thereof or included therein by the Securities Act or otherwise pursuant to the Rules and Regulations, is herein called the

“Registration Statement.” If the Company has filed or files an abbreviated registration statement in connection with the Shares pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term Registration Statement shall include such Rule 462 Registration Statement. The Company will file with the Commission pursuant to Rule 430B and Rule 424 under the Securities Act a final prospectus supplement relating to the Shares to the form of prospectus included in the Registration Statement. The prospectus included in the Registration Statement at the time it was declared effective by the Commission is herein referred to as the “Base Prospectus.”

The Company has filed or proposes to file with the Commission pursuant to Rule 424 under the Securities Act a preliminary prospectus supplement relating to the Shares (along with the Base Prospectus, the “Preliminary Prospectus Supplement”) and a final prospectus supplement relating to the Shares (the “Final Prospectus Supplement”). The Final Prospectus Supplement together with the Base Prospectus is hereinafter referred to as the “Final Prospectus.” The Preliminary Prospectus Supplement together with the Base Prospectus is hereinafter called a “Prospectus.” Any reference herein to the Base Prospectus, the Preliminary Prospectus Supplement, the Final Prospectus Supplement, the Final Prospectus or a 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 Rule 462 Registration Statement, the Base Prospectus, the Final Prospectus, any 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 or its Interactive Data Electronic Applications system. All references in this Agreement to financial statements and schedules and other information which is “described,” “contained,” “included” or “stated” in the Registration Statement, the Rule 462 Registration Statement, the Base Prospectus, the Final Prospectus or any Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements, pro forma financial information and schedules and other information which is incorporated by reference in or otherwise deemed by the Rules and Regulations to be a part of or included in the Registration Statement, the Rule 462 Registration Statement, the Base Prospectus, the Final Prospectus or any Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, the Rule 462 Registration Statement, the Base Prospectus, the Final Prospectus or any 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”), that is deemed to be incorporated therein by reference or otherwise deemed by the Rules and Regulations to be a part thereof.

will comply in all material respects with the requirements of the Securities Act and the Rules and Regulations and did not and will not, as the case may be, 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 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 or any post-effective amendment thereto, the Time of Sale Disclosure Package or the Final Prospectus in reliance upon, and in conformity with, written information furnished to the Company through the Representative by or on behalf of any Underwriter specifically for use in the preparation thereof. The Registration Statement (including each document incorporated by reference therein) contains all exhibits and schedules required to be filed by the Securities Act or the Rules and Regulations. No order preventing or suspending the effectiveness or use of the Registration Statement or any Prospectus is in effect and no proceedings for such purpose have been instituted or are pending, or, to the knowledge of the Company, are threatened by the Commission.

(ii) The documents incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package and the Final Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, were filed on a timely basis with the Commission and none of such documents, when they were filed (or, if amendments to such documents were filed, when such amendments were filed), contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Any further documents so filed and incorporated by reference in the 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. As used in this paragraph and elsewhere in this Agreement, “Time of Sale Disclosure Package” means the Base Prospectus, the Prospectus most recently filed with the Commission before the time of this Agreement, including any preliminary prospectus supplement deemed to be a part thereof, each issuer free writing prospectus as defined in Rule 433 of the Securities Act (each, an “Issuer Free Writing Prospectus”) identified in Schedule II, and any description of the transaction provided by the Underwriter included on Schedule III, all considered together as of 5:00 a.m. pacific standard time on May 3, 2016 (the “Time of Sale”).

(iii) (A) The Company has not made, used, prepared, authorized, approved or referred to any Issuer Free Writing Prospectus in the sale of Shares, except

for those Issuer Free Writing Prospectuses identified in Schedule II hereto. The Company has filed all Issuer Free Writing Prospectuses required to be so filed with the Commission, and no order preventing or suspending the effectiveness or use of any Issuer Free Writing Prospectus is in effect and no proceedings for such purpose have been instituted or are pending, or, to the knowledge of the Company, are threatened by the Commission. When taken together with the rest of the Time of Sale Disclosure Package or the Final Prospectus, since its first use and at all relevant times since then, no Issuer Free Writing Prospectus has, does or will include (1) any untrue statement of a material fact or omission to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (2) information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Final Prospectus. The representations and warranties set forth in the immediately preceding sentence shall not apply to statements in or omissions from the Time of Sale Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company through the Representative by or on behalf of any Underwriter specifically for use in the preparation thereof.

(B) Each Issuer Free Writing Prospectus satisfied, as of its issue date and at all subsequent times through the Prospectus Delivery Period, all other conditions as may be applicable to its use as set forth in Rules 164 and 433 under the Securities Act, including any legend, record-keeping or other requirements.

Except as otherwise included in the Registration Statement, Time of Sale Disclosure Package and the Final Prospectus, no other financial statements, pro forma financial information or schedules are required under the Securities Act to be included or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus.

5. Covenants. The Company covenants and agrees with the Underwriters as follows:

(a) During the period beginning on the date hereof and ending on the later of the Closing Date or such date as determined by the Representative that the Final 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, including any Rule 462 Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus, the Company shall furnish to the Representative 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 the Representative reasonably objects.

(b) From the date of this Agreement until the end of the Prospectus Delivery Period, the Company shall promptly advise the Representative 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 or any amendment or supplement to the Time of Sale Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus, (C) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending its use or the use of the Time of Sale Disclosure Package, the Final 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 during the Prospectus Delivery Period 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.

(c) (i) 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 Registration Statement, the Time of Sale Disclosure Package and the Final Prospectus. If during the Prospectus Delivery Period any event occurs the result of which would cause the Final Prospectus (or if the Final 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 reasonable opinion of the Company or its counsel or the Representative or the Underwriters’ counsel to amend the Registration Statement or supplement

-13-

the Final Prospectus (or if the Final 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 Final Prospectus in order to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Representative and will amend the Registration Statement or supplement the Final Prospectus (or if the Final 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.

(ii) During the Prospectus Delivery Period, if at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development the result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the 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 Representative 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.

(d) 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 Representative reasonably designates 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 qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified, 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 jurisdiction in which it is not otherwise subject.

(e) The Company covenants that it will not, unless it obtains the prior written consent of the Representative, 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. In the event that the Representative expressly consents in writing to any such free writing prospectus (a “Permitted Free Writing Prospectus”), the Company covenants that it shall (i) treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) comply with the requirements of Rule 164 and 433 of the Securities Act applicable to such Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(f) The Company will furnish to the Representative and counsel for the Underwriters copies of the 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 the Representative may from time to time reasonably request.

(g) 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

-14-

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.

(h) The Company 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.

(i) Whether or not the transactions contemplated hereunder are consummated, 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 (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Shares, the Time of Sale Disclosure Package, any Prospectus (including the Final 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 Underwriters’ counsel incurred in connection with the qualification of the Shares for offering and sale by the Underwriters or by dealers under the securities or blue sky laws of the states and other jurisdictions that the Representative shall designate, (D) the fees and expenses of any transfer agent or registrar, (E) listing fees, if any, (F) the reasonable fees and reasonable disbursements of Underwriters’ counsel incident to any required review and approval by FINRA of the terms of the sale of the Shares, (G) the reasonable out-of-pocket expenses of the Underwriters, including reasonable legal fees and disbursements of counsel to the Underwriters, in connection with the purchase and sale of the Shares contemplated hereby in an amount, when taken together with (C) and (F) above, not to exceed $125,000 in the aggregate and (H) all other costs and expenses of the Company incident to the performance of the Company’s obligations hereunder that are not otherwise specifically provided for herein. Except for reimbursement from the Company of any of the fees and costs described in (A) through (H) above that are paid by the Underwriters, and notwithstanding any other provision hereof, the Underwriters will pay all of their own fees and costs in connection with the transactions described herein, including, without limitation, the Underwriters’ attorney’s fees and costs, any transfer taxes on the resale of any Shares by the Underwriters and any marketing, advertising and “road show” expenses incurred by the Underwriters. If this Agreement is terminated for any reason, neither the Company nor any Underwriter shall be entitled to any reimbursement of fees or expenses from the other, except for those reimbursements expressly described in this Section 5(i).

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

(k) The Company hereby agrees that, without the prior written consent of the Representative, it will not, during the period ending on and including the 90^th day after the date hereof (as the same may be extended as described below, the “Lock-Up Period”), (i) offer, pledge, issue, sell, contract to sell, purchase, contract to purchase, lend, or otherwise transfer or

-15-

dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock; or (ii) 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 (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (iii) 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 other than registration statements on Form S-8 relating to Company equity incentive plans that are in existence and disclosed in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus. 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 Final Prospectus or the vesting of the 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) and the Final Prospectus (4) except as set forth in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus, the issuance of Common Stock or warrants to purchase Common Stock, in an amount not to exceed 19.0% of the total number of shares of Common Stock outstanding on the date hereof, in connection with mergers or acquisitions of securities, businesses, property or other assets, joint ventures, strategic alliances, equipment leasing arrangements or debt financing; and (5) the issuance of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock to affiliates of the Company in an amount not to exceed 19.0% of the total number of shares of Common Stock outstanding on the date hereof.

7. Certain Agreements of the Underwriters. The Underwriters hereby represent and agree, severally and not jointly, that they have not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus,” as defined in Rule 405 of the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely a result of use by an Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 of the Securities Act, (ii) any Issuer Free Writing Prospectus, or (iii) any free writing prospectus prepared by any Underwriter and approved by the Company in advance in writing.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify, defend and hold harmless each Underwriter, its affiliates, directors and officers and employees, and 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, from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or such person 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, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Registration Statement or the Final Prospectus), or any Issuer Free Writing Prospectus, or in any materials or information provided to investors by, or with the written approval of, the Company, in connection with the marketing of the Offering of the Shares, including any roadshow or investor presentations (whether in person or electronically) (“Marketing Materials”) 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, (with respect to the Time of Sale Disclosure Package, the Final Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus and any Marketing Materials, in light of the circumstances under which they were made), not misleading, (ii) in whole or in part, any inaccuracy in the representations and warranties of the Company contained herein, or (iii) in whole or in part, any failure of the Company to perform its obligations hereunder or under law, and will reimburse such Underwriter for any legal or other expenses reasonably incurred by it in connection with evaluating, investigating or defending against such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action (or any legal or other expense reasonably incurred in connection with the evaluation, investigation or defense thereof) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company through the Representative by or on behalf of any Underwriter specifically for use in the preparation thereof.

-19-

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company, its affiliates, directors, officers and employees, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Company or such person 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, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Marketing Materials, 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 (with respect to the Time of Sale Disclosure Package, the Final Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus and any Marketing Materials, in light of the circumstances under which they were made), 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, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, any issuer Free Writing Prospectus or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company through the Representative by or on behalf of 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 evaluating, investigation 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 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 under such subsection 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 the 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 the reasonable 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

-20-

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 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) or (b) of this Section 8, in which event the reasonable and documented fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the indemnified party 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 8 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.

(d) If the indemnification provided for in this Section 8 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 Underwriters, on the other hand, from the Offering 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, on the one hand, and the Underwriters, on the other hand, 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 Underwriters, on the other hand, 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 total underwriting discounts and commissions received by the Underwriters, in each case as set forth 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 by or on behalf of the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters 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 that does not take account of the equitable considerations referred to in the first

-21-

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 that is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount of such Underwriter’s discounts and commissions actually received by the Underwriter from the Offering of the Shares. 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 8 shall be in addition to any liability that 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 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 8 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 Company, and its 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.

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

9. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements herein or in certificates delivered pursuant hereto including, but not limited to, the agreements of the Underwriters and the Company contained in Section 8 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 Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Shares hereunder.

10. Termination of this Agreement.

(a) The Representative 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 the Nasdaq Capital Market or trading in securities generally on the Nasdaq Global Market, New York Stock Exchange or NYSE Amex 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 Nasdaq Global Market, New York Stock Exchange or NYSE Amex, by

-22-

[●], 2016

Roth Capital Partners, LLC

888 San Clemente Drive

Newport Beach, California 92660

Ladies and Gentlemen:

The undersigned understands that Roth Capital Partners, LLC (“Roth”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Revolution Lighting Technologies, Inc., a Delaware corporation (the “Company”) providing for the public offering (the “Public Offering”) of shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”).

To induce Roth to continue its efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Roth, it will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus supplement relating to the Public Offering (the “Prospectus”) (the “Lock-Up Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant 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 (2) 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 (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) shall be required or shall be voluntarily made during the Lock-Up Period in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions, (b) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift, by will or intestacy or to a family member or trust for the benefit of a family member; provided that in the case of any transfer or distribution pursuant to clause (b), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) if the undersigned is required to file a report under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock during the Lock-Up Period, the undersigned shall include a statement in such report to the effect that such transfer is being made as a gift, by will or intestate succession, as applicable, or (c) transfers upon a vesting event of the Company’s securities or upon the exercise of options or warrants to purchase the Company’s securities, in each case on a “cashless” or “net exercise”

basis or to cover tax withholding obligations of the undersigned in connection with such vesting or exercise, provided that any related filing under Section 16(a) of the Exchange Act reporting a disposition of shares of Common Stock made in connection with such vesting or exercise shall contain a description of the transaction and indicate that the disposition was made as part of such vesting or exercise or to cover tax withholding obligations in connection therewith, (d) transfers pursuant to a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act established prior to the date hereof, (e) transfers to an entity directly or wholly owned by the undersigned, (f) pledges of the Company’s securities as collateral for a loan from a bank or other financial institution, subject to such lender agreeing in writing to be similarly bound by this agreement for the remainder of the Lock-Up Period, (g) transfers to a third party pursuant to the acquisition of 100% of the voting stock of the Company by such third party or (h) transfers that occur by operation of law, such as pursuant to a qualified domestic order or in connection with a divorce settlement. In addition, the undersigned agrees that, without the prior written consent of Roth, it will not, during the period commencing on the date hereof and ending 90 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. 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 the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

No provision in this agreement shall be deemed to restrict or prohibit the exercise or exchange by the undersigned of any option or warrant to acquire shares of Common Stock, or securities exchangeable or exercisable for or convertible into Common Stock, provided that the undersigned does not transfer the Common Stock acquired on such exercise or exchange during the Lock-Up Period, unless otherwise permitted pursuant to the terms of this agreement. In addition, no provision herein shall be deemed to restrict or prohibit the entry into or modification of a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act at any time (other than the entry into or modification of such a plan in such a manner as to cause the sale of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock within the Lock-Up Period).

The undersigned understands that the Company and Roth are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. The undersigned understands that, if (i) the Underwriting Agreement is not executed by June 1, 2016, (ii) the Company notifies Roth in writing that it does not intend to proceed with the Public Offering or (iii) the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, the undersigned shall be released from all obligations under this letter agreement.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and Roth.

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