F1	Represents the number of shares of Common Stock vested pursuant to the performance-based restricted stock unit ("PRSU") award that was granted on January 22, 2019 and reported voluntarily on the Form 4 filed with the Securities and Exchange Commission on January 24, 2019, based upon the determination that 62% of the PRSU vested given that the issuer's total shareholder return ranked at the 32.33 percentile as compared to the Russell 2000 Index over the performance period.
F2	Represents restricted stock units granted on January 19, 2022 which will vest in three equal installments on the anniversary of the grant date.
F3	The number of PRSUs reported in Table II represents the target number of PRSUs that were granted to the reporting person pursuant to the Issuer's 2020 Equity Incentive Plan. Per the terms of the award agreement governing the PRSUs, the number of underlying shares of the Issuer's common stock that the reporting person is ultimately entitled to receive at the time of vesting ranges from 0% to 200% of the target number of PRSUs granted, subject to how the Issuer's total shareholder return ranks in comparison to companies that comprise the Russell 2000 Index over a performance period consisting of the three years ended December 31, 2024.
