1. Board of Directors.

(a) New Director. As soon as reasonably practicable following the execution of this Agreement, the Board and all applicable committees thereof shall take (or shall have taken) such actions to appoint John Mehas (the “New Director”) as a member of the Board with an initial term expiring at the Company’s 2024 Annual Meeting of Stockholders (the “2024 Annual Meeting”). The Company’s slate of nominees for the election of directors at the 2024 Annual Meeting shall include the New Director as a nominee. The Company will recommend that the Company’s stockholders vote in favor of the election of the New Director at the 2024 Annual Meeting and will support the New Director for election in a manner consistent with its support for the other nominees of the Company.

In accordance with the Board’s customary governance processes, the Board will give the New Director the same due consideration for Board committee membership as any other non-management director with similar expertise and qualifications. The New Director shall not disclose to any Barington Party or any of their Affiliates or any other person or entity not affiliated with the Company any confidential information of the Company, and each Barington Party shall not, and shall cause

their respective Affiliates not to, seek to obtain confidential information of the Company from the New Director. Each of the Barington Parties agrees that the New Director may not share any information with the Barington Parties in respect of the Company which he learns in his capacity as a director of the Company, including discussions or matters considered in meetings of the Board or any Board committee, at any time, for any reason, without the Company’s prior consent.

(d) Termination. The Company’s obligations under this Section 1 shall terminate upon any material breach of this Agreement by any Barington Party or any of their Affiliates, as applicable, upon five business days’ written notice by the Company to the Barington Parties if such breach has not been cured within such notice period, provided that the Company is not in material breach of this Agreement at the time such notice is given or prior to the end of such notice period.

(e) Irrevocable Letter of Resignation. Concurrently with the New Director’s appointment to the Board and as a condition to the Company’s obligations under this Agreement, the New Director will execute and deliver an irrevocable letter of resignation in the form attached hereto as Exhibit B.
