1.    Duties and Scope of Employment.

(a)    Positions and Duties. Effective as of the Effective Date, Executive will serve as the Company’s Sr. Vice President, Chief Operating Officer. Executive will render such business and professional services in the performance of Executive’s duties, consistent with Executive’s position within the Company, as will reasonably be assigned to Executive by the Company’s Chief Executive Officer. The period of Executive’s employment under this Agreement is referred to herein as the “Employment Term.”

(b)    Obligations. During the Employment Term, Executive will perform Executive’s duties faithfully and to the best of Executive’s ability and will devote Executive’s full business efforts and time to the Company. For the duration of the Employment Term, Executive agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior approval of the Company’s board of directors (the “Board”), except as provided in Schedule 1.

2.    At-Will Employment. The parties agree that Executive’s employment with the Company will be“at-will” employment and may be terminated at any time with or without Cause or notice. Executive understands and agrees that neither Executive’s job performance nor promotions, commendations, bonuses or the like from the Company give rise to or in any way serve as the basis for modification, amendment, or extension, by implication or otherwise, of Executive’s employment with the Company. However, as described in this Agreement, Executive may be entitled to severance benefits depending on the circumstances of Executive’s termination of employment with the Company.

3.    Compensation.

(a)    Base Salary. Effective as of the Effective Date, the Company will pay Executive an annual salary of $300,000.00 as compensation for Executive’s employment services to the Company (the “Base Salary”). The Base Salary will be paid periodically in accordance with the Company’s normal payroll practices and be subject to the usual, required withholdings. Executive’s annual salary will be subject to review and adjustments as may be made based upon the Company’s normal performance review practices. The Company may modify job titles, salaries and benefits from time to time as it deems necessary.

(b)    Target Bonus. Beginning with calendar year 2018, Executive will be eligible to receive an annual discretionary bonus of up to thirty-five percent (35%) of Executive’s Base Salary upon achievement of performance objectives to be determined by the Board in its sole

discretion (the “Target Bonus”). The Target Bonus will be prorated for the calendar year in which Executive commences employment based on the number of days Executive is employed with the Company in the calendar year. The Target Bonus, or any portion thereof, will be paid, less applicable withholdings, as soon as practicable after the Board determines that the Target Bonus has been earned, but in no event shall the Target Bonus be paid after the later of (i) the fifteenth (15^th) day of the third (3^rd) month following the close of the Company’s fiscal year in which the Target Bonus is earned or (ii) March 15 following the calendar year in which the Target Bonus is earned. Executive’s Target Bonus will be subject to review and adjustments as may be made based upon the Company’s normal performance review practices.

(c)    Stock Option. Subject to the approval of the Board (or a committee thereof), Executive will be granted a nonstatutory stock option to purchase 82,000 shares of the Company’s common stock at an exercise price per share equal to the fair market value on the date of grant (the “Option”). Subject to the accelerated vesting provisions set forth herein, the Option will vest as to 25% of the shares subject to the Option one (1) year after the Effective Date, and as to 1/48th of the shares subject to the Option monthly thereafter on the same day of the month as the Effective Date (and if there is no corresponding day, the last day of the month), so that the Option will be fully vested and exercisable four (4) years from the Option’s date of grant, subject to Executive continuing to provide services to the Company through the relevant vesting dates. Except as provided herein, the Option will be subject to the terms and conditions of an equity incentive plan and related stock option agreement approved by the Board (or a committee thereof), including vesting requirements (collectively, the “Equity Documents”). No right to any stock is earned or accrued until such time that vesting occurs, nor does the grant confer any right to continue vesting or employment.

4.    Employee Benefits. During the Employment Term, Executive will be entitled to participate in the employee benefit plans currently and hereafter maintained by the Company of general applicability to other senior executives of the Company. The Company reserves the right to cancel or change the benefit plans and programs it offers to its employees at any time.

5.    Expenses. The Company will reimburse Executive for reasonable travel, entertainment or other expenses incurred by Executive in the furtherance of or in connection with the performance of Executive’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time.

6.    Severance.

(a)    Termination for other than Cause, Death or Disability Apart from a Change of Control. If, outside of the Change of Control Period, (i) the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause, death or Disability, or (ii) the Executive resigns from such employment for Good Reason, then, subject to Section 7, Executive will be entitled to receive:

(i)    continuing payments of severance pay for a period of nine (9) months at a rate equal to (x) the sum of (A) seventy-five percent (75%) of Executive’s Base Salary rate, as then in effect,plus (B) the sum of all performance bonuses paid to Executive for the Company’s fiscal year immediately preceding the fiscal year in which Executive’s termination of employment

-2-

occursdivided by(y) nine (9). The severance will be paid, less applicable withholdings, in installments over the severance period described herein with the first payment to commence on the sixty-first (61st) day following Executive’s termination of employment (and include any severance payments that otherwise would have been paid to Executive within the sixty (60) days following Executive’s termination date), with any remaining payments paid in accordance with the Company’s normal payroll practices for the remainder of the severance period following Executive’s termination of employment (subject to any delay as may be required by Section 7(c)).

(ii)    if Executive elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) within the time period prescribed pursuant to COBRA for Executive and Executive’s eligible dependents, then the Company will provide Executive for the COBRA premiums for such coverage (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a period of nine (9) months from the date of termination or (B) the date upon which Executive and/or Executive’s eligible dependents are no longer eligible for COBRA continuation coverage. Notwithstanding the first sentence of this Section 6(a)(ii), if the Company determines in its sole discretion that it cannot provide the foregoing benefit without potentially violating, or being subject to an excise tax under, applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a taxable monthly payment, payable on the last day of a given month (except as provided by the following sentence), in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue the group health coverage for Executive and/or Executive’s eligible dependents in effect on the termination of employment date (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether Executive and/or Executive’s eligible dependents elect COBRA continuation coverage and will commence on the month following Executive’s termination of employment and will end on the earlier of (x) the date upon which Executive obtains other employment or (y) the date the Company has paid an amount equal to nine (9) payments. Any such taxable monthly payments that otherwise would have been paid to Executive within the sixty (60) days following Executive’s termination date instead will be paid on the sixty-first (61st) day following Executive’s termination of employment, with any remaining payments paid as provided in the prior sentence (subject to any delay as may be required by Section 7(c)).

(b)    Termination for other than Cause, Death or Disability or Resignation by Executive for Good Reason Related to a Change of Control. If, within the Change of Control Period (i) the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause, death or Disability, or (ii) the Executive resigns from such employment for Good Reason, then, subject to Section 7, Executive will be entitled to receive:

(i)    a lump sum payment equal to one hundred and fifty percent (150%) of the sum of: (A) Executive’s Base Salary, as then in effect, or if greater, at the level in effect immediately prior to the Change of Control,plus(B) Executive’s Target Bonus in effect for the fiscal year in which Executive’s termination of employment occurs. The severance will be paid, less applicable withholdings, on the sixty-first (61st) day following Executive’s termination of employment in accordance with the Company’s normal payroll practices (subject to any delay as may be required by Section 7(c)). For the avoidance of doubt, if (x) Executive incurred a

-3-

termination of employment prior to a Change of Control that qualifies Executive for severance payments under Section 6(a)(i); and (y) a Change of Control occurs within the three (3)-month period following Executive’s termination of employment that qualifies Executive for the superior benefits under this Section 6(b)(i), then Executive shall be entitled to alump-sum payment of the amount calculated under this Section 6(b)(i), less amounts already paid under Section 6(a)(i).

(ii)    if Executive elects continuation coverage pursuant to COBRA within the time period prescribed pursuant to COBRA for Executive and Executive’s eligible dependents, then the Company will provide Executive for the COBRA premiums for such coverage (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a period of eighteen (18) months from the date of termination or (B) the date upon which Executive and/or Executive’s eligible dependents are no longer eligible for COBRA continuation coverage; and

(iii)    accelerated vesting as to one hundred percent (100%) of Executive’s then-outstanding equity awards to acquire Company common stock.

(c)    Termination for Cause, Death or Disability; Resignation without Good Reason. If Executive’s employment with the Company (or any parent or subsidiary or successor of the Company) terminates voluntarily by Executive (except upon resignation for Good Reason), for Cause by the Company or due to Executive’s death or Disability, then (i) all vesting will terminate immediately with respect to Executive’s outstanding equity awards, (ii) all payments of compensation by the Company to Executive hereunder will terminate immediately (except as to amounts already earned), and (iii) Executive will only be eligible for severance benefits in accordance with the Company’s established policies, if any, as then in effect.

(d)    Exclusive Remedy. In the event of a termination of Executive’s employment with the Company (or any parent or subsidiary or successor of the Company), the provisions of this Section 6 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive or the Company may otherwise be entitled, whether at law, tort or contract, in equity, or under this Agreement, including any prior employment agreements entered into between the Company and Executive. Executive will be entitled to no severance or other benefits upon termination of employment with respect to acceleration of award vesting or severance pay other than those benefits expressly set forth in this Section 6.

7.    Conditions to Receipt of Severance; No Duty to Mitigate.

(a)    Separation Agreement and Release of Claims. The receipt of any severance pursuant to Section 6(a) or (b) will be subject to Executive signing and not revoking a separation agreement and release of claims in a form reasonably satisfactory to the Company (the “Release”) and provided that such Release becomes effective and irrevocable no later than sixty (60) days following the termination date(such deadline, the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, Executive will forfeit any rights to severance or benefits under this Agreement. In no event will severance payments or benefits be paid or provided until the Release becomes effective and irrevocable.

(b)    Nonsolicitation. The receipt of any severance benefits pursuant to Section 6(a) or (b) will be subject to Executive not violating the provisions of Section 11. In the

-4-

event Executive breaches the provisions of Section 11, all continuing payments and benefits to which Executive may otherwise be entitled pursuant to Section 6(a) or (b) will immediately cease.

(c)    Section 409A.

(i)    Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to Executive, if any, pursuant to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Code Section 409A, and the final regulations and any guidance promulgated thereunder (“Section 409A”) (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A. Similarly, no severance payable to Executive, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury RegulationSection 1.409A-1(b)(9) will be payable until Executive has a “separation from service” within the meaning of Section 409A.

(ii)    Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments that are payable within the first six (6) months following Executive’s separation from service, will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service, but prior to the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a separate payment for purposes ofSection 1.409A-2(b)(2) of the Treasury Regulations.

(iii)    Any amount paid under this Agreement that satisfies the requirements of the “short-term deferral” rule set forth inSection 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause (i) above.

(iv)    Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from service pursuant toSection 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for purposes of clause (i) above.

(v)    The foregoing provisions are intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A. Executive agrees and acknowledges that

-5-

the Company makes no representations or warranties with respect to the application of Section 409A and other tax consequences to any payments hereunder and, by the acceptance of any such payments, Executive agrees to accept the potential application of Section 409A and the other tax consequences of any payments made hereunder.

(d)    Confidential Information Agreement. Executive’s receipt of any payments or benefits under Section 6 will be subject to Executive continuing to comply with the terms of Confidential Information Agreement (as defined in Section 10).

(e)    No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment.

(a)    Cause. For purposes of this Agreement, “Cause” is defined as (i) the willful failure, disregard, or refusal by Executive to perform the services hereunder or follow the reasonable instructions of the Board;provided,however, that any willful failure, disregard, or refusal by Executive to perform the services hereunder that can reasonably be cured shall not constitute Cause unless cure is not effected, as determined in good faith by the Board, within thirty (30) days after notice thereof is received by the Executive from the Company; (ii) any willful or grossly negligent act by the Executive having the effect of injuring, in a material way (whether financial or otherwise) as determined in good faith by the Board, the business or reputation of the Company or any of its subsidiaries or affiliates; (iii) Executive’s conviction of, guilty plea, or plea of nolo contendere to any felony or a misdemeanor involving moral turpitude; (iv) the determination by the Company, after a reasonable and good faith investigation by the Company following a written allegation by an employee of the Company, that the Executive engaged in some form of harassment prohibited by law (including, without limitation, age, sex, disability, or race discrimination) unless Executive’s actions were specifically directed by the Board; or (v) material breach by the Executive of any provision of this Agreement or any Confidential Information Agreement.

(ii)    a change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company

Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.

(g)    Section 409A Limit. For purposes of this Agreement, “Section 409A Limit” will mean two (2) times the lesser of: (i) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during the Executive’s taxable year preceding the Executive’s taxable year of Executive’s separation from service as determined under Treasury RegulationSection 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Internal Revenue Code for the year in which Executive’s separation from service occurred.

9.    Limitation on Payments. In the event that the severance and other benefits provided for in this Agreement or otherwise payable to Executive (the “Payments”) (i) constitute “parachute payments” within the meaning of Section 280G of the Code and (ii) but for this Section 9, would be subject to the excise tax imposed by Section 4999 of the Code, then Executive’s Payments will be either:

(a)    delivered in full, or

(b)    delivered as to such lesser extent which would result in no portion of such severance benefits being subject to the excise tax under Section 4999 of the Code,

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by Executive on anafter-tax basis, of the greatest amount of Payments, notwithstanding that all or some portion of such Payments may be taxable under Section 4999 of the Code. If a reduction in the Payments constituting “parachute payments” is necessary so that no portion of such Payments is subject to the excise tax under Section 4999 of the Code, the reduction shall occur in the following order: (1) reduction of the cash severance payments; (2) cancellation of accelerated vesting of equity awards; and (3) reduction of continued employee benefits. In the event that acceleration of vesting of equity award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of Executive’s equity awards.

The Company shall bear all expenses with respect to the determinations by the Firm required to be made hereunder.

Any good faith determinations of the Firm made hereunder shall be final, binding, and conclusive upon the Company and Executive.

10.    Confidential Information. Executive agrees to execute and comply with the Company’sAt-Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement (the “Confidential Information Agreement”) concurrently with the execution of this Agreement and agrees to abide by the Company’s rules and standards. Executive understands that Executive must disclose to the Company any and all agreements relating to Executive’s prior employment that may affect Executive’s eligibility to be employed by the Company or limit the manner in which Executive may be employed. It is the Company’s understanding that any such agreements will not prevent Executive from performing the duties of Executive’s position and Executive represents that such is the case. Executive agrees not to bring any third party confidential information to the Company, including that of Executive’s former employers, and that in performing Executive’s duties for the Company, Executive will not in any way utilize any such information.

11.    Non-Solicitation. Until the date one (1) year after the termination of Executive’s employment with the Company for any reason, Executive agrees not, either directly or indirectly, to solicit any employee of the Company (or any parent or subsidiary of the Company) to leave Executive’s employment either for Executive or for any other entity or person.

None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution.
