(a) The parties agree that the Employee’s employment with the Company shall continue through the Severance Date and cease for all purposes effective on the Severance Date. From January 11, 2022 until the Severance Date, Employee shall remain employed by the Company and assist in an orderly transition of duties, information, and

Unless otherwise advised and authorized, to do so, Employee shall not hold himself out after the Severance Date as an Employee, agent or representative of the Company and shall have no authority to bind the Company or any of its affiliates in any manner. The Employee shall also be deemed to have resigned from the office of Chief Financial Officer on January 11, 2022, and any other corporate officer or corporate director position which he held as an incident of his employment with the Company as of January 11, 2022, and further agrees, at the Company’s request, to take all reasonably necessary steps to effectuate such resignation(s).

(b) The Employee shall continue to be covered through January 31, 2022 under the Company’s group health, dental and vision insurance plans (the “Health Insurance Plans”) with the same coverage, deductibles and other plan conditions as existed on the Severance Date. The Employee shall receive a notice of continuation rights under the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1986, as amended (“COBRA”). Nothing in this Separation Agreement and General Release shall serve to modify, alter or supersede the Employee’s statutory rights to continuation coverage (“Continuation Coverage”).

2.Payment of Accruals; No Other Vested Rights.

(a) The Employee acknowledges prior receipt of and full payment for all time worked through November 25, 2021. All outstanding and future wages and other payments, including accrued PTO and other emoluments made and to be made to the Employee hereunder, shall be made via direct deposit in the same manner as paid during Employee’s employment to date. Employee acknowledges he has no claim for any bonus payment(s). Employee acknowledges and agrees that Employee owes the Company $700 from the latest expense reimbursement submitted.

(b) Employee and Company acknowledge and agree that all unused and accrued vacation leave, sick leave or similar accruals shall be paid in accordance with the Company’s standard policy applicable to all employees.

(d)The Employee acknowledges, understands and agrees that 100,000 of the 200,000 Restricted Stock Units previously granted to him under the Plan and Restricted Stock Unit Award Agreement to which he is a party, shall, as a result of his severance of employment and as a result of the provisions of this Separation Agreement and General Release, lapse, terminate and be immediately forfeited.

(e)The Company acknowledges and agrees that, as of the Effective Date, Employee has vested stock option grants totaling 86,457 option shares (the “Option Shares”).

3.Equity Incentive Acceleration which forms the Consideration for Employee’s Waiver and General Release of All Claims.

The foregoing to the contrary notwithstanding, the Company intends to accelerate the vesting of certain of the 200,000 Restricted Stock Units previously granted to Employee under the Plan. In consideration of his execution of this Separation Agreement and General Release and its provisions, 75,000 Restricted Stock Units shall vest on the Effective Date of this Agreement. Such vesting, along with the vesting described in Section 2(c) above, represents the total amount of Restricted Stock Units which shall vest, and which Employee shall receive in consequence of

any unvested equity, shares or lapsed and other rights in the 2020 Equity Incentive Plan and Restricted Stock Unit Award Agreement to which he is a party.

(b) All payments made to the Employee hereunder shall be made net of all necessary and lawful withholdings and deductions, including those for income taxes.
