On August 5, 2025, Brian L.

•A cash bonus under the Company’s Annual Incentive Bonus Plan will be paid at the “target” level pro-rated from January 1, 2025 through the Separation Date.

•All outstanding restricted stock units will vest on a pro rata basis through the Separation Date.

•All outstanding performance stock units will vest based on the “target” award amount set forth in each award on a pro rata basis through the Separation Date.

•After the Separation Date, Mr. Tucker will remain subject to the clawback provision of the Employment Agreement, the regulations of the New York Stock Exchange or the Company’s Clawback Policy.
