 (ii) The Executive shall devote his best efforts and his full business time and attention
(except for permitted vacation periods and reasonable periods of illness or other incapacity) to the business and affairs of the Company. The Executive shall perform his duties and responsibilities to the best of his abilities in a diligent,
trustworthy, businesslike and efficient manner. Notwithstanding the foregoing, the Executive may, to the extent not otherwise prohibited by this Agreement, devote such amount of time as does not interfere or compete with the performance of the
Executive’s duties under this Agreement to any one or more of the following activities: (i) engaging in charitable activities, including serving on the boards of directors of charitable organizations or (ii) serving on the board of
directors of any other company with the prior written approval of the Company. 
 (b) Salary and Benefits. 

(i) During the Employment Period, the Executive’s base salary shall be $275,000 per year (such annual salary, as it may be
adjusted upward by the Board or a committee thereof in its discretion, being referred to as the “Base Salary”). The Base Salary shall be payable in regular installments in accordance with the Company’s general payroll
practices, shall be subject to customary withholding and may be increased (but not decreased) at the discretion of the Board or a committee thereof. 

(ii) In addition to the Base Salary, Executive shall be eligible to receive an annual cash incentive bonus payment (each, a
“Performance Bonus”) in an amount, if any, to be determined by the Company’s Board or a committee thereof. The Performance Bonus is deemed earned only if the Executive is employed on the last day of the year to which the

(iii) The Company will reimburse the Executive for all reasonable travel and other expenses incurred by the Executive in connection
with the performance of his duties and obligations under this Agreement. The Executive shall comply with such reasonable limitations and reporting requirements with respect to expenses as may be established by the Company from time to time. 

(iv) In addition, the Executive will be entitled to participate in all compensation or employee benefit plans or programs and receive
all benefits and perquisites for which salaried employees of the Company generally are eligible under any plan or program now or established later by the Company on the same basis as similarly situated senior executives of the Company. The Executive
will participate to the extent permissible under the terms and provisions of such plans or programs, in accordance with program provisions. Nothing in this Agreement will preclude the Company from amending or terminating any of the plans or programs
applicable to salaried employees or senior executives of the Company as long as such amendment or termination is applicable to all salaried employees or senior executives, as the case may be, so long as such plans or programs are replaced with plans
no less favorable, in the aggregate, than existing plans. 
 (c) Employment at Will. The Executive and the Company understand
and agree that the Executive is an employee at will, and that the Executive may resign, or the Company may terminate the Executive’s employment, at any time and for any or for no reason. Nothing in this Agreement shall be construed to alter the
at-will nature of the Executive’s employment, nor shall anything in this Agreement be construed as providing the Executive with a definite term of employment or guaranteed nature or amount of compensation.

 (d) Severance. If the Executive’s employment with the Company is terminated
(i) by the Company without Cause; or (ii) by the Executive for Good Reason within thirty (30) days after the occurrence of an event constituting Good Reason (including the expiration of any applicable cure periods), the Executive
shall be entitled to (i) payment of the Executive’s Base Salary (prior to any reduction) for a period of three (3) months following the date of such termination; (ii) continued participation on substantially similar terms in all
employee benefit plans and programs to which he was entitled to participate in as of the date of such termination for three (3) months following the date of such termination; and (iii) receive any accrued but unpaid bonuses or commissions
fully earned by the Executive in accordance with Section 2(b)(ii) above (collectively, the “Severance Benefits”). The Executive hereby agrees that no severance compensation shall be payable upon termination of the
Executive’s employment with the Company (i) by the Company with Cause; (ii) by the Executive without Good Reason; or (iii) as a result of the Executive’s death or Permanent Disability, and the Executive hereby waives any
claim for severance compensation except as set forth in this Section 2(d). Executive’s entitlement to the Severance Benefits is subject to and conditioned upon his execution without revocation of the Release as set forth in
Section 2(i) below. 
 (e) Termination or Reduction of Severance. If at any time after termination of
employment hereunder the Executive breaches any of the provisions set forth in any Related Agreement, and if the Executive fails to cure each such breach, in all material respects, within thirty (30) days after the Company has given to the
Executive written notice of such breach, the Executive shall no longer be entitled to any of the Severance Benefits pursuant to Section 2(d) above. 

(f) Change of Control. In addition to the provisions of Section 2(d), if a Change of Control occurs and the
Executive (i) does not receive an offer to remain employed by the Company for at least two years following the Change of Control in the position specified in Section 2(a)(i) above (or equivalent position) at a comparable rate of
compensation, bonus, benefits and other material terms as set forth in this Agreement (including severance and termination provisions); and (ii) the Executive is terminated without Cause or resigns for any reason within the two year period
following the Change of Control event, the Executive shall be entitled upon his termination of employment to receive the Severance Benefits. Executive’s entitlement to the Severance Benefits is subject to and conditioned upon his execution
without revocation of the Release as set forth in Section 2(i) below. 
 (g) Options. The Executive will be
granted an option to purchase shares of the Company’s common stock (the “Option”). The terms of the Option will be set forth in a stock option grant notice and incorporated stock option agreement (the “Grant”)
and will be subject to the Company’s 2011 Employee, Director and Consultant Equity Incentive Plan (the “Plan”). Notwithstanding any terms in the Grant or the Plan to the contrary: 

(i) upon (A) a Change of Control event, unless the Executive receives an offer to remain employed by the Company for at least two
years following the Change of Control event in the position specified in Section 2(a)(i) above (or equivalent position) at a 

  
 4 








 
comparable rate of compensation, bonus, benefits and other material terms as contained in this Agreement; (B) the termination of the Executive’s employment with the Company without
Cause or by the Executive for Good Reason at any time during the two (2) year period following the Change of Control event, the vesting of the Option will be accelerated such that the portion of the Option that would have vested (x) in the
time period between the date of termination or Change of Control event, whichever is applicable, and the next anniversary of the Vesting Start Date (as such term is defined in the Grant) following the Change of Control event or date of termination,
and (y) in the time period between such anniversary of the Vesting Start Date following the Change of Control event or date of termination and the immediately following anniversary of the Vesting Start Date, will be vested as of the Change in
Control event or date of termination; and 
 (ii) if upon a merger, consolidation or sale of all or substantially all of the
Company’s assets (a “Corporate Transaction”) the Option does not continue in the form of equity in the successor or acquiring entity such that vesting may continue to accrue after the Corporate Transaction then immediately
prior to such Corporate Transaction the vesting of the Option will be accelerated such that the portion of the Option that would have vested (x) in the time period between the Corporate Transaction and the next anniversary of the Vesting Start
Date following the Corporate Transaction, and (y) in the time period between such anniversary of the Vesting Start Date following the Corporate Transaction and the immediately following anniversary of the Vesting Start Date, will be vested.

 (h) Parachute Payments. If Independent Tax Counsel (as that term is defined below) determines that the aggregate
payments and benefits provided or to be provided to the Executive pursuant to this Agreement, and any other payments and benefits provided or to be provided to the Executive from the Company or any of its subsidiaries or other affiliates or any
successors thereto constitute “parachute payments” as defined in Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) (or any successor provision thereto) (“Parachute Payments”)
that would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then, except as otherwise provided in the next sentence, such Parachute Payments shall be reduced to the extent the Independent Tax
Counsel shall determine is necessary (but not below zero) so that no portion thereof shall be subject to the Excise Tax. If Independent Tax Counsel determines that the Executive would receive in the aggregate greater payments and benefits on an
after tax basis if the Parachute Payments were not reduced pursuant to this Section 2(h), then no such reduction shall be made. The determination of which payments or benefits shall be reduced to avoid the Excise Tax shall be made by the
Independent Tax Counsel, provided that the Independent Tax Counsel shall reduce or eliminate, as the case may be, payments or benefits in the order that it determines will produce the required deduction in total Parachute Payments with the least
reduction in economic value to the Executive of such payments. The determination of the Independent Tax Counsel under this Section 2(h) shall be final and binding on all parties hereto. For purposes of this Section 2(h),
“Independent Tax Counsel” shall mean a lawyer, a certified public accountant with a nationally recognized accounting firm, or a compensation consultant with a nationally recognized actuarial and benefits consulting firm with expertise in
the area of executive compensation tax law, who shall be selected by the Board, and whose fees and disbursements shall be paid by the Company.

 (i) Severance and Release. The Executive’s right to receive the Severance
Benefits shall be contingent upon the Executive’s execution and non-revocation (other than in the case of Executive’s death) within forty-five (45) days of his date of termination of a general release reasonably satisfactory to the
Company releasing the Company, its officers, agents, stockholders, and affiliates from any liability for any matter other than for payments under this Agreement and contractual obligations under other written agreements which form shall be provided
to the Executive on or prior to his date of termination (the “Release”). The Company hereby agrees that upon the lapse of the period for revocation set forth in the Release, if any, if the Executive has not exercised his revocation
right, the Company will execute a counterpart of the Release and deliver it to Executive forthwith. The payment of the Severance Benefits shall commence in the sixty (60) day period following the Executive’s date of termination; provided
that if a new calendar year commences during this period, the payments shall commence no earlier than January 1 of such new calendar year. The first payment after execution of the Release shall include all amounts that would have been paid
following the date of termination had the Release been effective immediately following the date of termination but which were not yet paid.

Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the prior written consent of the Company and the Executive. 

(i) Compliance with Code Section 409A. To the extent that any payment under this Agreement constitutes “nonqualified
deferred compensation” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), (i) a termination of employment shall not be deemed to have occurred for purposes of any provision of this
Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any
such provision of this Agreement, references to a “termination ,” “termination of employment” or like terms shall mean “separation from service,” (ii) the Executive’s right to receive any installment payments
pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments, and (iii) if the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term
under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered deferred compensation under Code Section 409A payable on account of a “separation from service,” such payment or
benefit shall be made or provided at the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such “separation from service” of Executive, and (B) the date of Executive’s
death, to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this Section 7(i) (whether they would have otherwise been payable in a single
sum or in installments in the absence of such delay) shall be paid in a lump sum, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.
