(1) Subject to the continuous status of Mr. Altman as a "Service Provider" (as defined in the Issuer's 2021 Equity Incentive Plan) through each applicable vesting date, one-twelfth (1/12th) of the shares subject to the Option shall vest on a monthly basis following the date of the grant on the same day of the month as such grant date.
(2) Consists of options to purchase shares of the Issuer's common stock awarded to Michael Altman in connection with his role as a member of the Issuer's Board of Directors. Mr. Altman is affiliated with Perceptive Advisors LLC (the "Advisor").

Each of Mr. Edelman, the Master Fund and the Advisor disclaims, for purposes of Section 16 of the Securities Exchange Act of 1934, beneficial ownership of the securities reported on this form, except to the extent of his/its indirect pecuniary interest therein, and this report shall not be deemed an admission that either Mr. Edelman, the Master Fund or the Advisor is the beneficial owner of such securities for purposes of Section 16 or for any other purposes.
