Mr. Stolper will participate in the Company's non-employee director compensation program. A complete description of the Company's non-employee director compensation program is set forth in the Company's proxy statement for the 2025 Annual Meeting of Stockholders, filed with the Securities and Exchange Commission on March 27, 2025 ("2024 Director Compensation").
