Explanation of Responses:

Id Content
F1 Equity grant under the Company's Amended and Restated 2014 Equity Incentive Plan.
F2 Represents the non-discretionary forfeiture of shares on behalf of the Reporting Person pursuant to an arrangement mandated by the Issuer to cover the tax withholding obligations associated with the vesting of the performance stock units ("PSUs") being reported herein.
F3 Each PSU represents a contingent right to receive, on vesting, one share of the Issuer's common stock, subject to Issuer performance as more specifically described in Footnote 4 herein.
F4 Vesting of the PSU was determined based on the Issuer's total stockholder return ("TSR") for the three-year period beginning on February 1, 2022 relative to the TSRs of the companies in the Russell 2000 index over that period. The number of PSUs reported in column 5 on the Form 4 filed with the Securities and Exchange Commission on February 3, 2022 reflected the target number of PSUs initially subject to the award. The award was eligible to vest as to 0% to 150% of the target number of PSUs. On February 5, 2025, the Compensation Committee of the Issuer's Board of Directors determined that, based on 124.83% achievement, the Reporting Person actually vested 108,360 shares.
