Explanation of Responses:
(1)  Represents restricted stock units ("RSUs") that vest on the earlier of (i) the one-year anniversary of June 10, 2021 (the "Grant Date") and (ii) the Issuer's next regularly scheduled annual meeting of stockholders that occurs following the Grant Date (the "Next Annual Meeting"), subject to the Reporting Person's continuous service as a non-employee director through such vesting date. Each RSU represents a contingent right to receive one share of Common Stock.
(2)  These shares are held directly by Longitude Venture Partners II, L.P. ("LVP II"). Longitude Capital Partners II, LLC ("LCP II") is the general partner of LVP II and may be deemed to have voting and investment power over the securities held by LVP II. Patrick G. Enright and Juliet Tammenoms Bakker are managing members of LCP II and may be deemed to share voting and investment power over the securities held by LVP II. The Reporting Person is a member of LCP II and may be deemed to share voting and investment power over the shares of the issuer held by LVP II. LCP II and each of these individuals disclaim beneficial ownership of such shares except to the extent of their respective pecuniary interests therein.
(3)  Subject to the Reporting Person's continuous service to the Issuer as a non-employee director through each vesting date, this option vests ratably on a monthly basis, on the monthly anniversary of June 10, 2021 ("Option Date"), over the one-year period following the Option Date so that the option shall be 100% vested and exercisable on the one-year anniversary of the Option Date ("Vesting Date"); provided, however, if the Next Annual Meeting occurs prior to the Vesting Date, then the option shall vest in full immediately prior to the Next Annual Meeting.
