        <footnote id="F1">Represents the number of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of Issuer's Restricted Stock Units. This sale is mandated by the Issuer's election under its equity incentive plans to require the satisfaction of tax withholding obligations to be funded by a &quot;sell to cover&quot; transaction and does not represent a discretionary trade by the Reporting Person.</footnote>
        <footnote id="F2">Represents an award of restricted stock units (&quot;RSUs&quot;) granted pursuant to the Issuer's 2019 Stock Option and Incentive Plan (the &quot;2019 Plan&quot;). Each RSU represents a contingent right to receive one share of the Issuer's common stock. Subject to the terms of the 2019 Plan, 33.33% of the RSUs will vest on December 1, 2024 and, thereafter, the remaining 66.67% of the RSUs will vest in 8 equal quarterly installments.</footnote>
