The Deep Track Parties expect that the Deep Track Nominees, if elected, may receive director compensation in the same amount as all other non-employeedirectors of the Company. The Deep Track Parties believe that the Company maintains, at its expense, a policy of insurance which insures its directors and officers. The Bylaws also contain provisions that, among other matters, provide for the indemnification of officers and directors to the fullest extent permitted by Delaware law. The Deep Track Parties expect that each of the Deep Track Nominees, if elected, will be indemnified in connection with his service as a director of the Company to the same extent as the current directors of the Company under the Bylaws and will be covered by the policy of insurance which insures the Company’s directors and officers. The share ownership level of each current non-employeedirector is set forth in the Company’s proxy statement for the 2025 Annual Meeting. None of the Deep Track Nominees nor any of their respective associates has received any cash compensation, cash bonuses, deferred compensation, compensation pursuant to plans, or other compensation, from, or in respect of, services rendered on behalf of the Company that is required to be disclosed under, or is subject to any arrangement described in Item 402 of Regulation S
