Pursuant to the Cooperation Agreement, the Company agreed to (i) appoint Neal J. Keating to the Company’s Board of Directors (the “Board”) and the Audit Committee of the Board (the “Audit Committee”) promptly after executing the Cooperation Agreement, (ii) nominate Mr. Keating for election to the Board at the Company’s 2026 annual meeting of stockholders (“2026 Annual Meeting”) and (iii) not increase the size of the Board to more than (a) ten (10) directors until the 2026 Annual Meeting and (b) nine (9) directors during the period following the 2026 Annual Meeting until the earlier to occur of (1) thirty (30) days prior to the deadline for the submission of stockholder nominations for the 2027 annual meeting of stockholders pursuant to the Company’s bylaws and (2) one hundred fifty (150) days prior to the one year anniversary of the date of the 2026 Annual Meeting (the “Expiration Date”); provided that the Board may increase its size to ten (10) directors with the consent of the Vision One Parties (which consent shall not be unreasonably withheld or delayed). The Cooperation Agreement provides that the Company and Vision One Parties will cooperate in good faith to select a mutually agreeable replacement director in the event that Mr. Keating ceases to serve as a director before the Expiration Date.

Pursuant to the Cooperation Agreement, the Vision One Parties agreed to withdraw their nominees for the 2026 Annual Meeting and to abide by certain customary standstill restrictions, mutual non-disparagement provisions, voting commitments, including supporting each director nominated and recommended by the Board for election, and other obligations until the Expiration Date.
