1.Board Composition and Related Matters.

(a)Appointment of New Directors. Immediately following the execution of this Agreement, the Board shall take all necessary actions to (i) increase the size of the Board to eleven (11) directors and (ii) appoint Dave Guilmette (the “New Class I Director”) and Coretha Rushing (the “New Class III Director” and together with the New Class I Director, collectively, the “New Directors”) to the Board, with Dave Guilmette being appointed as a Class I director with a term expiring at the 2025 annual meeting of stockholders (the “2025 Annual Meeting”) and Coretha Rushing being appointed as a Class III director with a term expiring at the 2024 Annual Meeting, or until their earlier death, disability, resignation, disqualification or removal.

(b)Committees. The Board and all applicable committees of the Board shall give each of the New Directors the same due consideration for committee membership as any other independent director; provided, however, that each of the New Directors shall be appointed to at least one committee of the Board; provided, further, that the New Class III Director shall be immediately appointed to the Compensation Committee of the Board.

(c)2024 Annual Meeting. The Company agrees to use its reasonable best efforts to hold the 2024 Annual Meeting no later than July 26, 2024, provided, however, that if the Board has made a Fiduciary Duty Determination (as defined below), the 2024 Annual Meeting shall be held in accordance with Section 1(e). If, at any time during the Standstill Period, the Board makes a Fiduciary Duty Determination, then the Company shall promptly notify Starboard in writing (such notice, the “Fiduciary Duty Determination Notice”) of such Fiduciary Duty Determination (which such notice shall provide a reasonable description of the events or circumstances giving

rise to such Fiduciary Duty Determination) no later than two (2) business day following a Fiduciary Duty Determination (the date such notice is delivered to Starboard, the “Notice Date”) and, in any event, at least one (1) business day prior to any public announcement of such Fiduciary Duty Determination.

(d)Replacement Rights. If the New Class III Director (or any Replacement Director (as defined below)) is unable or unwilling to serve as a director and ceases to be a director, resigns as a director or is removed as a director, is not elected as a director at the 2024 Annual Meeting or for any other reason fails to serve or is not serving as a director at any time prior to the expiration of the Standstill Period, and at such time Starboard beneficially owns (as determined under Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) in the aggregate at least the lesser of 3% of the Company’s then-outstanding Class A Common Stock, par value $0.0001 per share (the “Common Stock”), and 16,510,383 shares of Common Stock (subject to adjustment for stock splits, reclassifications, combinations, and similar adjustments), Starboard shall have the right to recommend a director candidate(s) to the Board to replace the New Class III Director as a director on the Board in accordance with this Section 1(d), which the Board shall consider in good faith in the exercise of the Board’s fiduciary duties under applicable law (any such person, if recommended by Starboard, shall be referred to as a “Replacement Director,” and if and when such person is appointed to the Board, shall be referred to as the New Class III Director (and a New Director) for purposes of this Agreement). Any replacement candidate recommended by Starboard must (A) be reasonably acceptable to the Board (such acceptance not to be unreasonably withheld, subject to the exercise by the Board of its fiduciary duties under applicable law), provided that in no event will the phrase “reasonably acceptable” or the parenthetical set forth in this clause (A) be construed to limit the Board’s right to exercise its fiduciary duties under applicable law, (B) qualify as “independent” pursuant to the New York Stock Exchange (the “NYSE”) listing standards, (C) have the relevant financial and business experience to serve as a director of the Company, (D) satisfy the Company’s publicly disclosed guidelines and policies with respect to service on the Board, including, without limitation, the Company’s Corporate Governance Guidelines, and (E) be independent of Starboard (for the avoidance of doubt, the nomination by Starboard of such person to serve on the board of any other company shall not (in and of itself) cause such person to not be deemed independent of Starboard, but any partner, officer, or employee of Starboard would not be deemed independent of Starboard) (in the case of each of clauses (B) through (D), as reasonably determined by the Nominating and Corporate Governance Committee of the Board (the “Nominating and Corporate Governance Committee”)). The Nominating and Corporate Governance Committee shall make its determination and recommendation (which it shall undertake reasonably and in good faith in the exercise of the Nominating and Corporate Governance Committee’s fiduciary duties under applicable law) regarding whether such candidate meets the foregoing criteria, assuming reasonable availability of such candidate, within ten (10) business days after the date (1) such candidate has submitted to the Company (a) a fully completed copy of the Company’s standard director and officer questionnaire and other reasonable and customary director onboarding documentation (including an authorization form to conduct a background check, a representation agreement, consent to be named as a director in the Company’s proxy statement and certain other agreements) required by the Company in connection with the appointment or election of new Board members, and (b) a written representation that such person, if elected as a director of the Company, would be in compliance, and will comply with, all applicable confidentiality, corporate governance, conflict of interest, Regulation FD, code of conduct and ethics, and stock ownership

2

and trading policies and guidelines of the Company, copies of which have been provided to such person prior to such date, and (2) representatives of the Board have, if requested by the Company, conducted customary interview(s) of such candidate. The Company shall use its reasonable best efforts to conduct any interview(s) contemplated by this Section 1(d) as promptly as practicable, but in any case, assuming reasonable availability of the nominee, within ten (10) business days after Starboard’s submission of such candidate. In the event the Nominating and Corporate Governance Committee does not accept a person recommended by Starboard, Starboard shall have the right to recommend additional candidates in accordance with the procedures described above. Upon the Nominating and Corporate Governance Committee’s recommendation of a replacement candidate, the Board shall vote on the applicable appointment of the Replacement Director to the Board no later than five (5) business days after the Nominating and Corporate Governance Committee’s recommendation of such replacement candidate; provided, however, that if the Board does not appoint such Replacement Director to the Board pursuant to this Section 1(d), the Parties shall continue to follow the procedures of this Section 1(d) until a Replacement Director is appointed to the Board. Subject to the NYSE rules and applicable law, and subject to the exercise by the Board of its fiduciary duties under applicable law, upon a Replacement Director’s appointment to the Board, the Board and all applicable committees of the Board shall take all necessary actions to appoint such Replacement Director to any applicable committee of the Board of which the former New Class III Director was a member immediately prior to such director’s departure. Notwithstanding the foregoing, if the Board makes a Fiduciary Duty Determination in connection with this Section 1(d), such that, following such Fiduciary Duty Determination, a Replacement Director is not appointed to the Board pursuant to this Section 1(d), then on the Notice Date, notwithstanding any other provision of this Agreement, all of Starboard’s (and its Affiliates’ and Associates’) obligations under Section 1(g)(iii), Section 1(g)(iv), Section 2 and Section 13 shall terminate.

(e)Board Size. Following the appointment of the New Directors until the conclusion of the 2024 Annual Meeting, the Company agrees that, unless the Board determines in good faith, after consultation with counsel, that its obligations under this Agreement, including this Section 1(e), would violate the Board’s fiduciary duties under applicable law (a “Fiduciary Duty Determination”), the size of the Board shall not exceed eleven (11) directors, without Starboard’s prior written consent, provided that the size of the Board may be increased to twelve (12) directors to accommodate the appointment of an additional independent director to the Board, as contemplated by the Press Release (as defined below) (the “Additional Independent Director”). Following the conclusion of the 2024 Annual Meeting through the expiration of the Standstill Period, the Company agrees that, subject to the exercise by the Board of its fiduciary duties under applicable law, (i) if the Additional Independent Director has been appointed to the Board prior to the 2024 Annual Meeting, the size of the Board shall not exceed eleven (11) directors, and (ii) if the Additional Independent Director has not been appointed to the Board, the size of the Board shall not exceed ten (10) directors, provided that the size of the Board may be increased by one (1) director to accommodate the appointment of the Additional Independent Director, and upon such appointment, the size of the Board shall not exceed eleven (11) directors, in each case without Starboard’s prior written consent. Notwithstanding the foregoing, if the Board makes a Fiduciary Duty Determination with respect to Section 1(e) such that, following such Fiduciary Duty Determination, the size of the Board exceeds the limits sets forth in this Section 1(e), then:

3

(i)on the Notice Date, notwithstanding any other provision of this Agreement, all of Starboard’s (and its Affiliates’ and Associates’) obligations under Section 1(g)(iii), Section 1(g)(iv), Section 2 and Section 13 shall terminate automatically and be of no further force or effect; and

(ii)if such Fiduciary Duty Determination occurs before the date of the 2024 Annual Meeting, the Company agrees that any additional Board seat(s) created (to the extent not yet filled) or any new director(s) appointed to the Board, in each case, as a result of increasing the size of the Board (the “Additional Board Seat(s)”), shall be up for election at the 2024 Annual Meeting, and

1.Starboard shall have fifteen (15) calendar days following the Notice Date to submit to the Company a notice, in accordance with the Company’s Amended and Restated By-laws (the “Bylaws”), nominating a number of director candidate(s) equal to the number of the Additional Board Seat(s) for election at the 2024 Annual Meeting and the Company shall deem any notice of nomination(s) submitted by Starboard during such period to have been timely submitted under the Bylaws; and

2.the Company agrees and will take all actions necessary to move the date of the 2024 Annual Meeting (if such date has already been set) so that both (x) the deadline under Rule 14a-19(b) under the Exchange Act in connection with the 2024 Annual Meeting is no earlier than fifteen (15) calendar days after the Notice Date and (y) the date of the 2024 Annual Meeting is held no earlier than sixty-five (65) calendar days following the Notice Date.

Notwithstanding the foregoing, as of the date of this Agreement, the Company is not aware of any information, facts and/or circumstances that would cause it to make a Recommendation Change with respect to the election of the New Class III Director to the Board at the 2024 Annual Meeting.

(ii)In the event of a Recommendation Change, the Company shall provide a Fiduciary Duty Determination Notice to Starboard in accordance with Section 1(e), and upon receipt of such Fiduciary Duty Determination Notice, notwithstanding Section 1(g)

12

of its agents, subsidiaries, Affiliates, successors, assigns, partners, members, officers, key employees or directors, in each case in their capacity as such, shall have breached this Section 13, neither it nor any of its respective agents, subsidiaries, Affiliates, successors, assigns, partners, members, officers, key employees or directors, in each case in their capacity as such, shall in any way publicly criticize, disparage, call into disrepute, or otherwise defame or slander the other Party or such other Party’s subsidiaries, Affiliates, successors, assigns, partners, members, officers (including any current officer of a Party or a Party’s subsidiaries who no longer serves in such capacity following the execution of this Agreement), directors (including any current officer or director of a Party or a Party’s subsidiaries who no longer serves in such capacity following the execution of this Agreement), employees, stockholders, agents, attorneys or representatives, or any of their businesses, products or services, in any manner that would reasonably be expected to damage the business or reputation of such other Party, their businesses, products or services or their subsidiaries, Affiliates, successors, assigns, officers (or former officers), directors (or former directors), employees, stockholders, agents, attorneys or representatives. The restrictions in this Section 13 shall not (a) apply (i) to any compelled testimony or production of information, whether by legal process, subpoena, or as part of a response to a request for information from any governmental or regulatory authority with jurisdiction over the party from whom information is sought, in each case to the extent required, or (ii) to any disclosure that such party reasonably believes, after consultation with outside counsel, to be legally required by applicable law, rules or regulations, in each case of clause (i) or (ii), solely to the extent that such restrictions would require a violation of the applicable requirement; or (b) prohibit any party from reporting what it reasonably believes, after consultation with outside counsel, to be violations of federal law or regulation to any governmental authority pursuant to Section 21F of the Exchange Act or Rule 21F promulgated thereunder.

14.Securities Laws. Starboard acknowledges that it is aware, and will advise each of its representatives who are informed as to the matters that are the subject of this Agreement, that the United States securities laws may prohibit any person who directly or indirectly has received from an issuer material, non-public information from purchasing or selling securities of such issuer or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities.

15.Entire Agreement; Amendment and Waiver; Successors and Assigns; Third Party Beneficiaries; Term. This Agreement contains the entire understanding of the Parties with respect to its subject matter.

No modifications of this Agreement can be made except in writing signed by an authorized representative of each of the Company and Starboard. No failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such Party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by law. The terms and conditions of this Agreement shall be binding upon, inure to the benefit of, and be enforceable by the Parties and their respective successors, heirs, executors, legal representatives, and permitted assigns.

for the benefit of the Parties and is not enforceable by any other persons or entities. This Agreement shall terminate at the end of the Standstill Period, except that (i) the provisions of Section 7, Sections 9 through 12 and Sections 14 and 15 shall survive termination and (ii) no termination shall relieve either Party from liability for any breach of this Agreement prior to such termination.
