Explanation of Responses:

Id	Content
F1	The securities described are restricted stock units and will fest in four equal installments on each of March 13, 2026, 2027, 2028 and 2029. Upon vesting Mr. Prior will receive a number of shares of common stock equal to the number of restricted stocks units that have vested.
F2	Each performance-based RSU ("PSU") represents a contingent right to receive one share of the Issuer's common stock, subject to the achievement of pre-established relative total shareholder return ("TSR") goals that were set by the Compensation Committee of the Issuer's Board of Directors, based on comparing the Issuer's TSR relative to the TSR of the Russell 2000 Index, using the average closing price of the shares for the 40 days before and including each of the first and last days of the applicable performance period. The aggregate number of shares issued may range from zero (0) shares to 150% of the target number of shares reported in columns 7 and 9 of this report.
F3	Between zero (0) and 150% of the PSUs will generally vest, if at all, as of the end of the performance period that begins on March 13, 2025, and ends on March 13, 2028.
