        <footnote id="F1">Mr. Nemiroff was awarded 12,400 restricted stock units. Each restricted stock unit represents a contingent right to receive one share of the Issuer's Common Stock. The restricted stock units vest in equal annual installments over a four-year period beginning on the one-year anniversary of the vesting commencement date of February 12, 2021. The restricted stock units may be settled only by delivering shares of the Issuer's Common Stock, and thus, the grant is being reported in Table 1 as allowed per SEC guidance.</footnote>
        <footnote id="F2">The shares underlying this stock option vest over a four-year period, with 25% vesting on the one-year anniversary of the vesting commencement date of February 12, 2021 and the remaining 75% vesting in 36 equal monthly installments following such first anniversary, subject to the reporting person's continued service through each vesting date.</footnote>
