Explanation of Responses:

Id	Content
F1	Represents restricted stock units of common stock. 1/3 of such shares will vest in three substantially equal installments on each of January 15, 2027, January 15, 2028 and January 15, 2029, provided that the Reporting Person is an employee of the Issuer or subsidiary of the Issuer on the vesting dates.
F2	Each restricted stock unit ("RSU") is the economic equivalent of one share of Common Stock.
F3	Represents market-based RSUs reflected at 100% of target performance that will be earned if the Company's total stockholder return ("TSR") over the period from November 1, 2025 through October 31, 2028 relative to the TSR of a set of peer companies in the Russell 2000 Index achieves a specified percentile target. The total range of RSUs that can be earned in this award is 0% to 200% of the target award. Once the number of RSUs earned pursuant to the market-condition have been determined, such RSUs will vest on January 15, 2029, provided that the Reporting Person is an employee of the Issuer or subsidiary of the Issuer of the vesting date.
