As described in Amendment 11, the Board of Directors (the “Board”) of the Company will grant Mr. Schaeffer an award of 229,657 shares of time-vesting restricted stock (the “Time Vesting Shares”) with respect to each of 2026, 2027 and 2028 (representing a value of $5 million with respect to 2026), and 321,520 shares of performance-vesting restricted stock (the “Performance Vesting Shares”) with respect to each of 2026, 2027 and 2028 (representing a value of $7 million with respect to 2026). With respect to 2026, the Company granted the Time Vesting Shares and Performance Vesting Shares on December 31, 2025. The Company will grant the Time Vesting Shares and Performance Vesting Shares for each of 2027 and 2028 provided Mr. Schaeffer is employed by the Company on January 1 of such year. The Time Vesting Shares granted in 2026 will vest on January 1, 2029, subject to Mr. Schaeffer’s employment through the term of the employment agreement (except in the case of certain qualifying terminations of employment). The Time Vesting Shares granted in 2027 and 2028 will vest in three equal annual installments beginning in January of the year following the year of the grant, subject to Mr. Schaeffer’s continued employment with the Company through each applicable vesting date (except in the case of certain qualifying terminations of employment).

The Performance Vesting Shares will be eligible to be earned on the first March 15 following the end of a three-year performance period, subject to Mr. Schaeffer’s continued employment with the Company through the last day of the performance period (except in the case of certain qualifying terminations of employment), and based upon the Company’s achievement of compound annual growth rate in EBITDA (“EBITDA CAGR”) over the performance period. If EBITDA CAGR is zero or negative, then no Performance Vesting Shares will vest. The performance targets which apply to the Performance Vesting Shares will be set by the Compensation Committee of the Board in its sole discretion. In the event of a material merger, acquisition, sale, divestiture or other business combination (materiality to be determined by the Committee in its sole discretion), the independent members of the Board may, in their good faith discretion, adjust one or more of the CAGR target percentages previously set for one of more of the tranches of shares of Performance Vesting Shares to prevent dilution or enlargement of the potential benefits intended to be made available under the applicable awards.
