        <footnote id="F1">The sales reported on this Form 4 were made by the reporting person pursuant to a trading plan adopted on December 14, 2020 that is intended to comply with Rule 10b5-1(c) under the Securities Exchange Act of 1934, as amended.</footnote>
        <footnote id="F2">Following the sales reported on this Form 4, the reporting person continues to beneficially own 210,159 shares of the Issuer's common stock. The reporting person also holds options to acquire an aggregate of 488,102 shares of the Issuer's common stock, 324,649 of which are exercisable as of the date hereof. Due to scrivener's error, footnote 2 of the Form 4 filed on behalf of the reporting person on July 19, 2021 inadvertently overstated the number of options held by the Reporting Person following the transaction reported therein. The amounts stated in this footnote 2 set forth the correct number of options held by the Reporting Person following the transaction reported herein.</footnote>
        <footnote id="F3">The reporting person was granted an option to purchase 149,203 shares of the Issuer's common stock on November 1, 2015. All of the shares underlying such stock option have vested and are exercisable as of the date hereof.</footnote>
