NOW, THEREFORE, in consideration of the promises, representations and mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows: 1. Board Composition and Other Company Matters. (a) Immediately following the execution of this Agreement, the Board, and all applicable committees of the Board, shall take all necessary actions to increase the size of the Board to eight (8) directors and shall appoint Xxxxxx Xxxx (the “New Director”), who shall fill the vacancy resulting from the newly created directorship, to the Board with a term expiring at the Company’s fiscal year 2025 annual meeting of stockholders (including any adjournments or postponements thereof and any meetings which may be called in lieu thereof, the “2025 Annual Meeting”).

2 (i) The Board, and all applicable committees of the Board, shall take all necessary actions to nominate and recommend the New Director as a candidate for election to the Board at each of the 2025 Annual Meeting, the Company’s fiscal year 2026 annual meeting of stockholders (including any adjournments or postponements thereof and any meetings which may be called in lieu thereof, the “2026 Annual Meeting”) and any other meeting of the Company’s stockholders held prior to the Termination Date (as defined below) at which directors are to be elected (an “Election Meeting”), and the Company agrees to recommend, support and solicit proxies for the election of the New Director at each of the 2025 Annual Meeting, the 2026 Annual Meeting and any Election Meeting, in a manner no less rigorous and favorable than the manner in which the Company supports the Board’s other nominees. (ii) As a condition to the Company’s obligation to appoint the New Director and nominate the New Director for election at each of the 2025 Annual Meeting, the 2026 Annual Meeting and any Election Meeting, the New Director shall be required to provide information required to be or customarily disclosed by directors or director candidates in proxy statements or other filings under applicable law or stock exchange regulations, information in connection with assessing eligibility, independence and other criteria applicable to directors or satisfying compliance and legal obligations, and a fully completed and executed copy of the Company’s director candidate questionnaire (in the form completed by the Company’s incumbent non-management directors), in each case, on the same basis as the Company’s incumbent non-management directors, to enable the timely filing of the Company’s proxy statement and other periodic reports with the Securities and Exchange Commission (the “SEC”). (b) The Company agrees that (i) the Board will neither nominate nor recommend that the stockholders of the Company vote to elect any incumbent directors serving on the Board as of the Effective Date other than Xxxxxxx X. Xxxxxxxxx, Xxxxxx X. Xxxx, Xxxxxxx X. Xxxxx, Xxxxxxx Xxxxxx, Xxxxxx X. Xxxxx, and Xxxxx Xxxxx at the 2025 Annual Meeting, (ii) the Board will neither nominate nor recommend that stockholders of the Company vote to elect any incumbent directors serving on the Board as of the Effective Date other than Messrs. Beindorff, Fife, Xxxxx and Xxxxx and Xx. Xxxxxx at the 2026 Annual Meeting and (iii) unless there is a vacancy on the Board at the time the Board approves its slate of director candidates for the Company’s fiscal year 2027 annual meeting of stockholders (including any adjournments or postponements thereof and any meetings which may be called in lieu thereof, the “2027 Annual Meeting”), the Board will neither nominate nor recommend that stockholders of the Company vote to elect any incumbent directors serving on the Board as of the Effective Date other than Messrs. Xxxx, Xxxxx and Xxxxx and Xx. Xxxxxx at the 2027 Annual Meeting; provided, however, that the foregoing shall not limit the Board’s right to nominate or recommend any non-incumbent director to fill any vacancy pursuant to Article FIFTH, Section B of the Certificate of Incorporation subject to the terms and conditions of Section 1(c) below. (c) The Company agrees that (i) from the Effective Date until the commencement of the 2026 Annual Meeting, the size of the Board shall be no greater than

3 eight (8) directors and (ii) from the closing of the 2026 Annual Meeting until the Termination Date, the size of the Board shall be no greater than seven (7) directors, in each case without the prior written consent of the Stockholder Parties. (d) Each Party acknowledges that the New Director, upon appointment to the Board, shall be governed by all of the same policies, processes, procedures, codes, rules, standards and guidelines applicable to all members of the Board, including, but not limited to, the Company’s Corporate Governance Guidelines, Code of Business Conduct and Ethics, Board Conflicts of Interest Policy, Xxxxxxx Xxxxxxx Policy and any other policies regarding stock ownership, public disclosures, legal compliance and confidentiality (collectively, the “Company Policies”), and will be required to adhere to the Company’s policies on confidentiality imposed on all members of the Board on the same basis as other members of the Board. The Company agrees that, upon appointment to the Board, the New Director shall receive (i) the same benefits of director and officer insurance as all other non-management directors on the Board, (ii) the same compensation for his service as a director as the compensation received by other non-management directors on the Board and (iii) such other benefits on the same basis as all other non-management directors on the Board. (e) If, from the Effective Date until the Termination Date, the New Director (or any Replacement (as defined below)) is unable or unwilling to serve as a director, resigns as a director, is removed as a director or otherwise ceases to be a director for any other reason, then the Stockholder Parties and the Company shall mutually agree upon a replacement director (a “Replacement”) to fill such vacancy created by the departing New Director (or any Replacement) being replaced (the “Former Director”). Any Replacement(s) identified pursuant to this Section 1(e) shall qualify as “independent” pursuant to The Nasdaq Stock Market LLC’s listing standards (or applicable requirement of such other national securities exchange designated as the primary market on which the Common Stock is listed for trading) and SEC rules and regulations, and such Replacement shall be expeditiously appointed to the Board, subject to the recommendation (not to be unreasonably withheld) of the Nominating and Corporate Governance Committee of the Board, after conducting a good faith customary due diligence process and consistent with its fiduciary duties. Any Replacement(s) appointed to the Board in accordance with this Section 1(e) shall be appointed to any applicable committees of the Board of which the Former Director was a member immediately prior to such Replacement’s appointment. Any rights or obligations of the Board and the Stockholder Parties as provided in this Section 1(e) shall terminate when the Stockholder Parties in the aggregate cease to beneficially own at least the lesser of (A) 5.0% of the Company’s then outstanding Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments) and (B) 643,423 shares of Common Stock. All references to the “New Director,” for purposes of this Agreement, shall be deemed references to the Replacement who replaces the Former Director in the event that a Replacement is appointed. Until the Termination Date, any Replacement designated pursuant to this Section 1(e) replacing the New Director prior to the mailing of the Company’s definitive proxy statement for the Company’s applicable annual meeting of stockholders shall stand for election at such meeting together with the Company’s other director nominees.

4 (f) Promptly following the appointment of the New Director to the Board, the Board and all applicable committees of the Board shall take such actions as are necessary to appoint the New Director to (i) the Audit Committee of the Board and (ii) the Nominating and Corporate Governance Committee of the Board. Without limiting the foregoing, the New Director shall be equally eligible for membership to any committee of the Board as any other independent director with similar relevant expertise and qualifications. (g) The Company agrees that the Board and all applicable committees of the Board shall take all necessary actions, no later than immediately following the execution of this Agreement, to determine, in connection with his initial appointment as a director and nomination by the Company at the 2024 Annual Meeting, that the New Director is deemed to be (i) a member of the “Incumbent Board” or “Continuing Director” (as such term may be defined in the definition of “Change in Control,” “Change of Control” (or any similar term) under the Company’s incentive plans, options plans, equity plans, deferred compensation plans, employment agreements, severance plans, retention plans, loan agreements, or indentures, or any other related plans or agreements that refer to any such plan, policy or agreement’s definition of “Change in Control” or any similar term) and (ii) a member of the Board as of the beginning of any applicable measurement period for the purposes of the definition of “Change in Control” or any similar term under the Company’s incentive plans, options plans, equity plans, deferred compensation plans, employment agreements, severance plans, retention plans, loan agreements, or indentures. 2. Withdrawal of Stockholder Demand and Related Matters. Concurrently with and effective upon the execution of this Agreement, the Stockholder Parties shall irrevocably withdraw or cause the irrevocable withdrawal of the Stockholder Parties’ letter to the Company, dated October 28, 2023, the Stockholder Demand and any and all related materials and notices submitted to the Company in connection therewith or related thereto, and shall not, and shall cause its Affiliates and Associates not to, directly or indirectly, take any further action in connection with the Stockholder Demand (other than in connection with such withdrawal or Section 11 hereof). 3. Voting. From the Effective Date until the Termination Date (the “Standstill Period”), each Stockholder Party agrees solely for and on behalf of itself that it will appear in person or by proxy at each annual or special meeting of stockholders of the Company (including any adjournments or postponements thereof and any meetings which may be called in lieu thereof), whether such meeting is held at a physical location or virtually by means of remote communications, and will vote (or execute a consent with respect to) all Voting Securities beneficially owned by it in accordance with the Board’s recommendations with respect to (a) each election of directors, any removal of directors and any replacement of directors, (b) the ratification of the appointment of the Company’s independent registered public accounting firm, (c) the Company’s “say-on-pay” proposal and (d) any other proposal to be submitted to the stockholders of the Company by either the Company or any stockholder of the Company; provided, however, that if Institutional Shareholder Services Inc. (“ISS”) and Glass Lewis & Co. LLC (“GL”) recommend otherwise with respect to any proposals (other than as related to the election, removal or replacement of directors, the authorization of shares, or the issuance of equity in connection with employee compensation), each Stockholder Party shall be permitted to vote in accordance with ISS’s and GL’s recommendation; provided, further, that each Stockholder Party shall be

5 permitted to vote in his or its sole discretion on any proposal of the Company in respect of any Extraordinary Transaction. 4. Mutual Non-Disparagement. (a) Until the Termination Date, each Stockholder Party agrees solely for and on behalf of itself that neither it nor any of its controlled Affiliates or Associates, directly or indirectly, shall make any public statement, or take any action that is intended to result in a public statement, that constitutes an ad hominem attack on, or otherwise disparages, defames or damages the reputation or good name of the Company, its Affiliates or Associates, or its independent consultants or is otherwise critical, negative towards or derogatory of the Company or its Affiliates, Associates or any of the Company’s directors, officers, employees, or independent consultants (in each case, solely in their capacities as such).

(c) Notwithstanding the foregoing, nothing in this Section 4 or elsewhere in this Agreement shall prohibit any Party from making any statement or disclosure required under the federal securities laws or other applicable laws (including, but not limited to, to comply with any subpoena or other legal process from any governmental or regulatory authority with competent jurisdiction over the relevant Party hereto) or stock exchange regulations. (d) The limitations set forth in Sections 4(a) or (b), as applicable, shall not prevent any Party from responding to any public statement made by the other Party of the nature described in Sections 4(a) or (b), as applicable, if such statement by the other Party was made in breach of this Agreement. 5. No Litigation. Prior to the Termination Date, each Party covenants and agrees solely for and on behalf of itself that he or it shall not, and shall not permit any of his or its Representatives (solely in the context of their representation of such Party in connection with the subject matter of this Agreement) to, alone or in concert with others, knowingly encourage or pursue, or knowingly assist any other person to threaten, initiate or pursue, any lawsuit, claim or proceeding (including, but not limited to, with respect to the Stockholder Parties, commencing, encouraging or supporting any derivative action in the name of the Company or any class action against the Company or any of its officers or directors, in each case with the intent of circumventing any terms of this Agreement) before any court or governmental, administrative or regulatory body (collectively, a “Legal Proceeding”) against (a) with respect to the Stockholder Parties, the Company or any of its Representatives (solely in the context of their representation of

In connection with any such claims, the Parties agree that they intend to waive, relinquish, and release any and all provisions, rights, and benefits any state or territory of the United States or other jurisdiction that purports to limit the application of a release to unknown claims, or to facts unknown at the time the release was entered into. In connection with this waiver, the Parties acknowledge that they, or any of them, may (including after the Effective Date) discover facts in addition to or different from those known or believed by them to be true with respect to the subject matter of the releases set forth in this Section 6, but it is the intention of the Parties to completely, fully, finally, and forever compromise, settle, release, discharge, and extinguish any and all claims arising out of or in any way related to the 2024 Annual Meeting or the Stockholder Demand that they may have one against the other, known or unknown, suspected or unsuspected, contingent or absolute, accrued or unaccrued, apparent or unapparent, that now exist or previously existed, without regard to the subsequent discovery of additional or different facts.
