Explanation of Responses:

Id Content
F1 Represents the number of shares that vested under a performance-based restricted stock unit award, which was granted on April 1, 2020, based on the Issuer's total stockholder return ("TSR") for the three-year period beginning on April 1, 2020 relative to the TSRs of the companies in the Russell 2000 index over that period, which vesting occurred on April 4, 2023. The vested shares represent the total number of shares earned under the performance-based restricted stock unit award, and the remainder reported in the Reporting Person's Form 4 filed with the Securities and Exchange Commission on April 3, 2020 were forfeited.
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 and settlement of the performance-based restricted stock units reported in footnote (1) herein.
F3 Each performance-based restricted stock unit represents a contingent right to receive on vesting one share of the Issuer's common stock.
