The option was granted pursuant to the Issuer's Non-Employee Director Compensation Program. 1/12th of the total number of shares of common stock subject to the option vest monthly following May 29, 2025, the date of grant. In the event the next occurring annual meeting of the Issuer's stockholders occurs prior to the first anniversary of the date of grant, any remaining unvested portion of the option will vest on the date of such annual meeting of the Issuer's stockholders, subject to the Reporting Person's continuous service to the Issuer through each vesting date. | Under the Reporting Person's arrangement with RA Capital Management, L.P. (the "Adviser"), the Reporting Person holds the stock option for the benefit of the RA Capital Healthcare Fund, L.P. (the "Fund"), the RA Capital Nexus Fund, L.P. (the "Nexus Fund"), and a separately managed account (the "Account"). The Reporting Person is obligated to turn over to the Adviser any net cash or stock received upon exercise of the stock option, which will offset advisory fees owed by the Fund, the Nexus Fund, and the Account. The Reporting Person therefore disclaims beneficial ownership of the stock option and underlying Common Stock.
