        <footnote id="F1">The nonqualified stock option vests in twelve equal quarterly installments, with the first quarterly installment vesting on June 30, 2019.</footnote>
        <footnote id="F2">The original Form 4, filed on June 21, 2019, is being amended by this Form 4 amendment solely to correct an administrative error, which misreported the number of derivative securities beneficially owned following the reported transaction that occurred on June 20, 2019 as a total of 938,083 shares of the Issuer's common stock. As a result of this administrative error, the number of shares beneficially owned by the reporting person following the corrected transaction reflects an increase in the number of shares reported as beneficially owned by the reporting person by 50,000 shares.</footnote>
