6. Severance Payments and Other Matters Related to Separation from Service.

Following the termination of the Employee’s employment for any reason, the Company shall pay to the Employee: (i) any Base Salary earned but not paid during the final payroll period of the Employee’s employment through the date of termination, (ii) pay for any vacation time earned but not used through the date of termination, (iii) any unpaid Discretionary Annual Bonus due to Employee for the calendar year prior to the year in which the termination occurs, and (iv) any business expenses incurred by the Employee but un-reimbursed on the date of termination, provided that such expenses and required substantiation and documentation are submitted within thirty (30) days of termination and that such expenses are reimbursable under Company policy (all of the foregoing, “Final Compensation”). Any Base Salary and any earned, unused vacation time shall be paid to the Employee at the time required by law, but not later than the Company’s next regular pay date following the date of termination. Any reimbursable business expenses shall be paid within sixty (60) days following the date that the Employee submits such expenses to the Company. Other than as expressly provided in Section 6(b), the Company shall have no further obligation to the Employee hereunder.

(b) Severance. In the event the Employee’s employment terminates pursuant to Section 5(a), 5(b), 5(d) or 5(e) of this Agreement, in addition to Final Compensation, (i) the vesting of all unvested equity awards of Parent or its Affiliates that vest solely based on the passage of time then held by Employee (including, without limitation, restricted stock, restricted stock units, stock options or other equity-based awards, whether granted to or held by Employee either before or after the date of this Agreement) shall accelerate by twelve (12) months (for the avoidance of doubt, with any equity awards that vest in whole or in part based on the attainment of performance-vesting conditions being governed by the terms of the applicable award agreement); and (ii) the Company shall pay the Employee (A) a lump sum equal to the Base Salary (such payment, the “Severance Payment”), (B) the Post-Termination Bonus (as defined below) and (C) an additional one-time bonus of $16,500 (such payment, the “One-Time Bonus”). Subject to Sections 6(d) and 7(a) of this Agreement (x) the Severance Payment and the One-Time Bonus shall be paid by the sixtieth (60th) day following the date of termination and (y) the Post-Termination Bonus shall be paid at or around the time that annual bonuses are paid to other similarly situated employees of the Company, but in no event later than March 15 of the year following the year in which the Separation from Service occurs; provided that if the termination occurs during the twelve (12) month period following a Change in Control, (i) the Post-Termination Bonus shall be paid by the sixtieth (60th) day following the date of termination and (ii) notwithstanding the provisions of the Parent’s 2018 Incentive Award Plan, the Parent’s 2015 Equity Incentive Plan or any other equity plan, the Employee shall be immediately 100% fully vested in all unvested equity awards of Parent or its Affiliates that vest solely based on the passage of time (including, without limitation, restricted stock, restricted stock units, stock options or other equity-based awards, whether granted to or held by Employee either before or after the date of this Agreement, and for the avoidance of doubt, with any equity awards that vest in whole or in part based on the attainment of performance-vesting conditions being governed by the terms of the applicable award agreement).

(c) Post-Termination Bonus. For the purposes of this Agreement, the “Post-Termination Bonus” shall be a pro-rata share of the Target Bonus for the calendar year in which the termination occurs; provided that if the termination occurs in the twelve (12) month period following a Change in Control, the Post-Termination Bonus shall be equal to the Target Bonus for the calendar year in which such termination occurs.

(d) Release of Claims. The Employee’s right to receive the payments and benefits set forth in Section 6(b) is conditioned on the Employee’s signing and returning to the Company (and not revoking) a general release of claims in the form provided by the Company at the time the Employee’s employment is terminated (the “Employee Release”). The Employee must sign and return the Employee Release, if at all, by the deadline specified therein, which deadline shall in no event be later than the sixtieth (60th) calendar day following the termination date. The Employee Release shall take effect on the expiration of any revocation period specified therein.

(e) Effect of Termination. Payment by the Company of Final Compensation and the payments and benefits set forth in Section 6(b) shall constitute the sole obligations of the Company in connection with the termination of the Employee’s employment hereunder. Except for any right of the Employee to continue medical and dental plan participation in accordance with applicable law, benefits shall terminate pursuant to the terms of the applicable benefit plans based on the date of termination of the Employee’s employment without regard to any of the payments set forth in Section 6(b).

(f) Survival. Provisions of this Agreement shall survive any termination if so provided herein or if necessary or desirable to accomplish the purposes of other surviving provisions, including without limitation the obligations of the Employee under Section 8 hereof. The obligation of the Company to make, and the right of the Employee to retain, any payments or benefits set forth in Section 6(b) is expressly conditioned upon the Employee’s continued full performance of obligations under Section 8, the Founder Invention and Non-Disclosure Agreement, and the Founder Non-Solicitation and Non-Competition Agreement.

7. Timing of Payments and Section 409A.

(a) Notwithstanding anything to the contrary in this Agreement, if at the time of the Employee’s termination of employment, the Employee is a Specified Employee (as defined below), such amounts that may be subject to the Specified Employee rules set forth at (a)(2)(B)(i) of Section 409A of the Code (“Section 409A”) and payable under Section 6 on account of such Separation from Service (as defined below) that would (but for this provision) be payable within six (6) months following the date of termination, shall instead be paid on the next business day following the expiration of such six (6) month period.

(b) For purposes of this Agreement, “Separation from Service” shall be determined in a manner consistent with subsection (a)(2)(A)(i) of Section 409A, and the term “Specified Employee” shall mean an individual determined by the Company to be a specified employee as defined in subsection (a)(2)(B)(i) of Section 409A.

(c) Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments.

(d) The Employee’s right to reimbursement for business expenses hereunder shall be subject to the following additional rules: (i) the amount of expenses eligible for reimbursement during any calendar year shall not affect the expenses eligible for reimbursement in any other taxable year, (ii) reimbursement shall be made not later than December 31 of the calendar year following the calendar year in which the expense was incurred, and (iii) the right to reimbursement is not subject to liquidation or exchange for any other benefit.

(e) In no event shall the Company have any liability relating to any payment or benefit under this Agreement failing to comply with, or be exempt from, the requirements of Section 409A.

8. Confidentiality; Cooperation

(a) Confidentiality and Other Covenants. As a condition of Employee’s employment with the Company, the Employee has executed the Founder Invention and Non-Disclosure Agreement and the Founder Invention and Non-Disclosure Agreement, both of which the Company and Employee acknowledge and agree shall be considered separate contracts. In addition, Employee represents and warrants that Employee shall be able to and will continue to perform the duties of Employee’s position without utilizing any material confidential and/or proprietary information that Employee may have obtained in connection with employment with any prior employer, and that Employee shall not (i) disclose any such information to the Company, or (ii) induce any Company employee to use any such information, in either case in violation of any confidentiality obligation, whether by agreement, by operation of law or otherwise.

(b) Litigation and Regulatory Cooperation. During and after Employee’s employment, Employee shall reasonably cooperate with the Company in the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while the Company employed Employee; provided that, the Employee will not have an obligation under this paragraph with respect to any claim that the Employee has filed directly against the Company or related persons or entities. The Employee’s reasonable cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times. During and after Employee’s employment, Employee also shall reasonably cooperate with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while Employee was employed by the Company, provided Employee will not have any obligation under this paragraph with respect to any claim that Employee has filed directly against the Company or related persons or entities. The Company shall reimburse Employee for any reasonable out-of-pocket expenses incurred in connection with Employee’s performance of obligations pursuant to this Section 8(b).

9. Section 280G; Limitations on Payment

(a) If any payment or benefit Employee shall or may receive from the Company or otherwise (a “280G Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then any such 280G Payment provided pursuant to this Agreement (a “Payment”) shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount (i.e., the amount determined by clause (x) or by clause (y)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Employee’s receipt, on an after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in a Payment is required pursuant to the preceding sentence and the Reduced Amount is determined pursuant to clause (x) of the preceding sentence, the

reduction shall occur in the manner (the “Reduction Method”) that results in the greatest economic benefit for Employee. If more than one method of reduction shall result in the same economic benefit, the items so reduced shall be reduced pro rata (the “Pro Rata Reduction Method”).

(b) Notwithstanding any provision of Section 9(a) to the contrary, if the Reduction Method or the Pro Rata Reduction Method would result in any portion of the Payment being subject to taxes pursuant to Section 409A that would not otherwise be subject to taxes pursuant to Section 409A, then the Reduction Method and/or the Pro Rata Reduction Method, as the case may be, shall be modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (i) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for Employee as determined on an after-tax basis; (ii) as a second priority, Payments that are contingent on future events (e.g., being terminated without Cause), shall be reduced (or eliminated) before Payments that are not contingent on future events; and (iii) as a third priority, Payments that are “deferred compensation” within the meaning of Section 409A shall be reduced (or eliminated) before Payments that are not deferred compensation within the meaning of Section 409A.

(c) Unless Employee and the Company agree on an alternative accounting firm or law firm, the accounting firm engaged by the Company for general tax compliance purposes as of the day prior to the effective date of the change of control transaction shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the change of control transaction, the Company shall appoint a nationally recognized accounting or law firm to make the determinations required by this Section 9. The Company shall bear all expenses with respect to the determinations by such accounting or law firm required to be made hereunder. The Company shall use commercially reasonable efforts to cause the accounting or law firm engaged to make the determinations hereunder to provide its calculations, together with detailed supporting documentation, to Employee and the Company within fifteen (15) calendar days after the date on which Employee’s right to a 280G Payment becomes reasonably likely to occur (if requested at that time by Employee or the Company) or such other time as requested by Employee or the Company.

(d) If Employee receives a Payment for which the Reduced Amount was determined pursuant to clause (x) of Section 9(a) and the Internal Revenue Service determines thereafter that some portion of the Payment is subject to the Excise Tax, Employee agrees to promptly return to the Company a sufficient amount of the Payment (after reduction pursuant to clause (x) of Section 9(a)) so that no portion of the remaining Payment is subject to the Excise Tax. For the avoidance of doubt, if the Reduced Amount was determined pursuant to clause (y) of Section 9(a), Employee shall have no obligation to return any portion of the Payment pursuant to the preceding sentence.

(e) Notwithstanding anything contained herein to the contrary, the requirements of this Section 9 shall apply only to the extent the Company has completed an “initial public offering” which results in the Company’s stock being publicly traded on an applicable public exchange.

10. Indemnification. The Company shall indemnify the Employee to the extent provided in its then current Certificate of Incorporation or By-Laws. The Employee agrees to promptly notify the Company of any actual or threatened claim arising out of or as a result of Employee’s employment with the Company. The parties acknowledge that the Employee is also indemnified by the Parent to the extent set forth in the Indemnification Agreement between the Parent and Employee dated December 16, 2015.

11. Withholding. All payments made by the Company under this Agreement shall be reduced by any tax or other amounts required to be withheld by the Company under applicable law.

12. Assignment.

(a) Neither the Company nor the Employee may make any assignment of this Agreement or any interest herein, by operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement without the consent of the Employee in the event that (i) the Employee is transferred to a position with any of the Affiliates or (ii) the Company shall hereafter effect a reorganization, consolidate with, or merge into, any Person or transfer all or substantially all of its properties or assets to any Person. This Agreement shall inure to the benefit of and be binding upon the Company and the Employee, their respective successors, executors, administrators, heirs and permitted assigns.

(b) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid.

13. Severability. If any covenants or such other provisions of this Agreement are found to be invalid or unenforceable by a final determination of a court of competent jurisdiction, (a) the remaining terms and provisions hereof shall be unimpaired, and (b) the invalid or unenforceable term or provision hereof shall be deemed replaced by a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision hereof.

14. Waiver. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure of either party to require the performance of any term or obligation of this Agreement, or the waiver by either party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

15. Notices. Any and all notices, requests, demands and other communications provided for by this Agreement shall be in writing and shall be effective when delivered in person, consigned to a reputable national courier service or deposited in the United States mail, postage prepaid, registered or certified, and addressed to the Employee at Employee’s last known address on the books of the Company or, in the case of the Company, at its principal place of business, attention of the Compensation Committee of the Parent Board with a copy to the attention of the Chief Legal Officer, or to such other address as either party may specify by notice to the other actually received. Any notice so addressed shall be deemed to be given or received (a) if delivered by hand, on the date of such delivery, (b) if mailed by courier or by overnight mail, on the first business day following the date of such mailing, and (c) if mailed by registered or certified mail, on the third business day after the date of such mailing.

16. Entire Agreement. This Agreement, together with the Founder Invention and Non-Disclosure Agreement and the Founder Non-Solicitation and Non-Competition Agreement, constitute the entire understanding and agreement of the Company and the Employee regarding the terms and conditions of Employee’s employment with the Company. This Agreement supersedes all prior

negotiations, discussions, correspondence, communications, understandings, and agreements between the Company and the Employee (including any offer letter given to Employee) relating to the subject matter of this Agreement, including (without limitation) the Original Agreement. Notwithstanding the foregoing, the Company and the Employee acknowledge that the Employee holds restricted stock of the Parent subject to a Restricted Stock Agreement and that options and other equity awards have been and, subject to the discretion and approval of the Parent Board, , may be granted to Employee under and pursuant to the Parent’s 2015 Equity Incentive Plan and any amendments thereto, as well as additional grants under the Parent’s 2018 Incentive Award Plan or any additional equity plans of the Parent or its Affiliates, and the award agreements related to such plans (collectively, the “Awards”); and to the extent that the terms of this Agreement (including without limitation, Section 6(b)) accelerate the vesting of any such Awards, then the terms of this Agreement are intended to be in addition to the vesting provisions of such Awards and are not intended to diminish any vesting rights contained in such Awards.

17. Amendment. This Agreement may be amended or modified only by a written instrument signed by the Employee and by an expressly authorized representative of the Company.

18. Headings. The headings and captions in this Agreement are for convenience only and in no way define or describe the scope or content of any provision of this Agreement.

19. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument.

20. Governing Law.
