The Executive agrees that Executive’s receipt of the compensation and benefits set forth in Section 9 (the “Severance Benefits”) shall be in lieu of all other claims that the Executive may make by reason of termination of Executive’s employment and that, as a condition to receiving the Severance Benefits, Executive, his estate or heirs will execute a general release of claims in a form satisfactory to the Company in its sole discretion (the “Release”). The Executive and the Company agree that the intent of such release is to ensure a final, complete, and enforceable release of all claims that the Executive has or may have against the Company relating to or arising in any way from the Executive’s employment with the Company and/or the termination thereof. Within five business days of the Termination Date, the

Company shall deliver to the Executive the form of release for the Executive to execute. The Executive will forfeit all rights to Severance Benefits unless the Executive executes and delivers to the Company the release within 45 days of delivery of the release by the Company to the Executive and such release has become irrevocable by virtue of the expiration of any revocation period (such time being the “Release Effective Date”). The Company shall have no obligation to provide Severance Benefits prior to the Release Effective Date occurs (and if the maximum period for execution and revocation of the Release spans two calendar years, payment shall be made or begin in the later taxable year).

(j)Section 409A. Notwithstanding any provision of this Agreement to the contrary, all provisions of this Agreement are intended to comply with Section 409A of the Internal Revenue Code of 1986 (the “Code”), and the applicable Treasury regulations and administrative guidance issued thereunder (collectively, “Section 409A”) or an exemption therefrom and shall be construed and administered in accordance with such intent. Any payments under this Agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this Agreement shall be treated as a separate payment. Any payments to be made under this Agreement upon a termination of Executive’s employment shall only be made if such termination of employment constitutes a “separation from service” under Section 409A to the extent necessary to comply with Section 409A. To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A), (i) any such expense reimbursement shall be made by the Company no later than the last day of Executive’s taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period in which the arrangement is in effect. Notwithstanding any provision in this Agreement to the contrary, if any payment or benefit provided for herein would be subject to additional taxes and interest under Section 409A if Executive’s receipt of such payment or benefit is not delayed until the earlier of (i) the date of Executive’s death or (ii) the date that is six months after the Termination Date (such date, the “Section 409A Payment Date”), then such payment or benefit shall not be provided to Executive (or Executive’s estate, if applicable) until the Section 409A Payment Date. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under this Agreement are exempt from, or compliant with, Section 409A and in no event shall the Company or any of its affiliates be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by Executive on account of non-compliance with Section 409A.

11.Effective Date. The effective date of this Agreement shall be the Start Date.

12.Clawback. Notwithstanding any other provisions in this Agreement, any Incentive-Based Compensation, as such term is defined in the Clawback Policy (as defined below) that is paid to Executive or that Executive may receive from the Company shall be subject to recovery or clawback by the Company under any reasonable, market-consistent clawback policy adopted by the Company from time to time (the “Clawback Policy”), provided such Clawback Policy is applicable to all executive officers of the Company, and provided further that, unless otherwise agreed to between the Executive and the Company or required by applicable law or stock exchange listing standards, such Clawback Policy shall not be applicable to Executive except to the extent a recovery or clawback of Incentive-Based Compensation is required under the Clawback Policy because the Company is required under GAAP, applicable securities laws, or applicable stock exchange listing standards to restate its financial statements with respect to fiscal periods ending after the Start Date due to material non-compliance with any financial reporting requirement under the federal securities laws (including any such correction that is material to the previously issued financial statements, or that would result in a material misstatement if

the error were corrected in the then current period or left uncorrected in the current period). Executive expressly acknowledges and agrees that in connection with the enforcement of such clawback policy, the Company shall have the right to reduce, cancel, or withhold against outstanding, unvested, vested, or future cash, equity or equity-based compensation owed or due to Executive and Executive agrees to repay to the Company any incentive compensation previously paid to Executive that is subject to such policy, in each case, to the maximum extent permitted under applicable law. No recovery of compensation under a clawback policy will be an event giving rise to a right to resign for Good Reason or “Constructive Termination” (or similar term) under any agreement with the Company.

13.PROTECTED CONDUCT NOTICE. Nothing in this Agreement prohibits Executive from (a) opposing an event or conduct that Executive reasonably believes is a violation of law, including criminal conduct, discrimination, harassment, retaliation or other unlawful employment practices, (b) disclosing sexual assault or sexual harassment; or (c) reporting such an event or conduct to their attorney, law enforcement, or the relevant law-enforcement agency (such as the Securities and Exchange Commission, Equal Employment Opportunity Commission, the state division of civil rights, or a local commission on civil rights), or (d) making any truthful statements or disclosures required by law or otherwise cooperating in an investigation conducted by any government agency (collectively referred to as “Protected Conduct”). Further, nothing requires notice to or approval from the Company before engaging in such Protected Conduct.

14.DTSA NOTICE. The DTSA provides that no individual will be held criminally or civilly liable under federal or state trade-secret law for the disclosure of a trade secret that: (a) is made in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and made solely for the purpose of reporting or investigating a suspected violation of law; or, (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal so that it is not made public. It also provides that an individual who pursues a lawsuit for retaliation by an employer for reporting a suspected violation of the law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding if the individual files any document containing the trade secret under seal and does not disclose the trade secret except as permitted by court order.

IN WITNESS WHEREOF, the parties have signed or caused this Agreement to be signed by their duly authorized officers as of the day and year first above written.
