        <footnote id="F1">Represents restricted stock units granted on November 19, 2025 under the Issuer's Amended and Restated 2020 Incentive Plan (the ''2020 Plan''). Shares subject to the award vest over four years from the date of grant, with 25% of the shares subject to the award vesting on the first anniversary of the date of grant and an additional 25% of the shares vesting on each subsequent anniversary of the date of grant thereafter.</footnote>
        <footnote id="F2">Represents target performance restricted stock units (''Performance RSUs'') granted on November 19, 2025 under the 2020 Plan, which vest based upon the achievement of certain performance criteria on the third anniversary of the date of grant (''Performance Period''). Performance criteria is the percentage increase in value of the Issuer's common stock compared to the percentage increase in value of the Russell 2000 Index over the Performance Period. The final potential payout will range
from 50% to 200% of the number of awarded target Performance RSUs, based on an attainment between 75% to 125% compared to the Russell 2000 Index. The attainment below 75% will result in a 0% payout.</footnote>
        <footnote id="F3">For the purposes of determining the percentage increase in value of the Issuer's common stock and the Russell 2000 Index, a hypothetical investment of $100 will be made in both the Issuer's common stock and the Russell 2000 Index with a purchase price equal to the average closing price of each for the 40-trading days immediately preceding the start of the Performance Period. At the end of the Performance Period, the value of the hypothetical investments shall be determined by assuming the sale of each based on the average closing price of each from the immediately preceding 40-trading days. The percentage change shall be determined by comparing the increase in value to the starting investment of $100.</footnote>
