2. The shares subject to the option shall vest on the earlier of (i) June 18, 2026 or (ii) the day prior to the date of the Issuer's 2026 annual meeting of stockholders.

3. RA Capital Management, L.P. (the "Adviser") is the investment manager for RA Capital Healthcare Fund, L.P. (the "Fund"). The general partner of the Adviser is RA Capital Management GP, LLC (the "Adviser GP"), of which Dr. Peter Kolchinsky and Mr. Rajeev Shah are the managing members. Each of the Adviser, the Adviser GP, Dr. Kolchinsky, and Mr. Shah disclaims beneficial ownership of any of the reported securities, except to the extent of its or his respective pecuniary interest therein.

4. Joshua Resnick is a Partner of the Adviser who serves on the Issuer's board of directors. Under Dr. Resnick's arrangement with the Adviser, Dr. Resnick holds the option for the benefit of the Fund. Dr. Resnick is obligated to turn over to the Adviser any net cash or stock received upon exercise of the option, which will offset advisory fees owed by the Fund to the Adviser. The Reporting Persons therefore disclaim beneficial ownership of the option and underlying common stock.
