1.Effective Date. Except as otherwise provided herein, this Agreement shall be effective on the eighth calendar day after it has been executed by both of the parties (the “Effective Date”), unless the Specified Sections (as defined in Section 13(c), below) have been timely and properly revoked as provided in Section 13(c) before the Effective Date.

2.Resignation of Employment; Paid Administrative Leave. The Employee has been employed by the Company as its Chief Operations Officer (“COO”) on an at-will basis pursuant to the employment offer letter signed by the Employee on August 3, 2018 (the “Employment Agreement”). The Employee resigned his employment with the Company on November 20, 2019 (the “Resignation Date”), to be effective at the close of business on January 10, 2020 (the “Separation Date”). The Employee acknowledges that that his active employment with the Company irrevocably and forever ended on the Resignation Date and will not be resumed at any time, and that he will have no duties and will be on a paid administrative leave until the Separation Date. The parties hereto agree that the Employment Agreement shall be terminated as of the Separation Date.

3.Continuation of Benefits After the Separation Date.

4.Final Wages. The Company will timely pay the Employee the unpaid portion of his annual salary earned through the Separation Date by having a check for that amount available for pick-up by sending it to the Employee by overnight mail or direct deposit transfer on that date.

5.Severance Payments. In return for the Employee’s promises in this Agreement, the Company will provide the Employee with severance payments, as follows:

(a)The amount of $519,021, which is equal to 100% of the Employee’s annual base salary in effect as of the date of the Separation Date, less standard payroll deductions and withholdings (the “Salary Severance”). The Salary Severance will be paid in a single, lump-

sum payment on the first scheduled Company payroll date after the Separation Date, as long as this Agreement has become effective.

(b)An amount not to exceed $259,510, which is equal to Employee’s target bonus opportunity representing 50% of the Employee’s annual base salary (the “Bonus Severance,” and collectively with the Salary Severance, the “Severance Payments”), with the amount of the Bonus Severance to be determined based on the Company’s actual results against the Company’s financial and other corporate goals of the Company’s bonus plan for fiscal year 2019 and provided that bonuses are awarded to other Company executives. The Bonus Severance will be paid in a single, lump-sum payment at the same time that bonuses for the current fiscal year are paid to other executives, as long as this Agreement has become effective.

Any vested Options and RSUs will, subject to this Agreement, be exercisable in accordance with the plan under which they were granted, and automatically will expire and be cancelled without consideration to the extent they are not exercised within the specified time period.

7.Waiver of Obligation to Repay Sign-On Bonus. The Company shall forgive and waive the obligation of the Employee under the Employment Agreement to repay his sign-on bonus in the amount of $200,000 as a result of his resignation in less than twenty-four (24) months after his hire date.
