5.Restrictive Covenants.

(a)Employee acknowledges and agrees that the restrictive covenants and other post-termination obligations set forth in Articles 6 through 9 of the Employment Agreement, dated as of August 13, 2024, between Employee and the Company (the “Employment Agreement”), including

3

without limitation Employee’s obligations relating to confidentiality, non-use and non-disclosure of Confidential Information, non-competition, non-solicitation, and return of property (the “Restrictive Covenants”), are hereby incorporated by reference and shall remain in full force and effect pursuant to their terms to the maximum extent permitted by applicable law; provided, however, the period during which the non-competition restrictions set forth in Section 9.01 of the Employment Agreement shall remain in effect shall end three (3) months following the Termination Date.

(b)Employee’s continued compliance with the Restrictive Covenants is a material condition to receipt of the Severance Benefits. In the event Employee breaches any part of such Restrictive Covenants, then, in addition to any remedies and enforcement mechanisms set forth in the Employment Agreement and this Agreement and any other remedies available to the Company (including equitable and injunctive remedies), Employee shall forfeit any Severance Benefits owing and shall be obligated to promptly return to the Company (within two (2) business days of any breach) the full gross amount of all Severance Benefits provided.

(c)If any provision of the Restrictive Covenants shall be determined to be unenforceable by any court of competent jurisdiction or arbitrator by reason of its extending for too great a period of time or over too large a geographic area or over too great a range of activities, it shall be interpreted to extend only over the maximum period of time, geographic area or range of activities as to which it may be enforceable.

6.Protected Disclosures. In accordance with 18 U.S.C. § 1833, notwithstanding anything to the contrary in this Agreement, the Employment Agreement and any other agreement between Employee and the Company (together, the “Subject Documents”): (a) Employee shall not be in breach of any Subject Document, and shall not be held criminally or civilly liable under any federal or state trade secret law (i) for the disclosure of a trade secret that is made in confidence to a federal, state, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) for the disclosure of a trade secret that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal; and (b) if Employee files a lawsuit for retaliation by the Company for reporting a suspected violation of law, Employee may disclose the trade secret to Employee’s attorney, and may use the trade secret information in the court proceeding, if Employee files any document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order. Furthermore, the Parties agree that nothing in the Subject Documents prohibits Employee from (x) communicating directly with, cooperating with, or providing information to, or receiving financial awards from, any federal, state or local government agency, including without limitation the U.S. Securities and Exchange Commission, the U.S. Commodity Futures Trading Commission, the U.S. Department of Justice, the U.S. Equal Employment Opportunity Commission, or the U.S. National Labor Relations Board, without notifying or seeking permission from the Company, (y) exercising any rights Employee may have under Section 7 of the U.S. National Labor Relations Act, such as the right to engage in concerted activity, including collective action or discussion concerning wages or working conditions, or (z) discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination based on a protected characteristic or any other conduct that Employee has reason to believe is unlawful.

7.Non-Disparagement. Employee promises not to make any statements or remarks, verbally or in writing, regarding anything at or about Releasees that could reasonably be anticipated to disparage, defame, or otherwise negatively affect the Releasees’ reputation in any manner, subject to the employee protections under Section 6. The Company promises to instruct its directors and officers not to make any statements or remarks, verbally or in writing, regarding Employee that could reasonably be

4

anticipated to disparage, defame, or otherwise negatively affect Employee’s reputation in any manner. The Company shall handle all requests for employment verification directed to its Human Resources Department in accordance with its standard employment verification policy and procedures to confirm dates of employment and position(s) held.

8.Severability. In the event that any provision or any portion of any provision hereof or any surviving agreement made a part hereof becomes or is declared by a court of competent jurisdiction or arbitrator to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision or portion of provision.

9.No Oral Modification. This Agreement may only be amended in a writing signed by Employee and a duly authorized officer of the Company.

10.Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on the advice of counsel if any questions as to the amount or requirement of withholding shall arise.

11.Governing Law; Dispute Resolution. This Release shall be subject to the provisions of Sections 12.15, 12.16 and 12.17 of the Employment Agreement.

12.Section 409A. All amounts payable under this Agreement are intended to be exempt from or to comply with the requirements of Section 409A of the Internal Revenue Code (together with any applicable regulations or guidance, “Section 409A”) and shall be interpreted consistently with such intent.
