Footnotes

F1: All shares subject to the option vest 100% on the first to occur of (i) June 7, 2024 or (ii) the day immediately preceding the first annual meeting of the Issuer's stockholders to occur after the date of grant of the award. Each grant, to the extent outstanding and otherwise unvested, will become fully vested should a "change in control" of the Issuer occur (as described in the applicable award agreement) or upon the Reporting Person's separation from service with the Issuer due to the Reporting Person's death or "disability" (as described in the applicable award agreement).

F2: RA Capital Management, L.P. (the "Adviser") is the investment manager for RA Capital Healthcare Fund, L.P. (the "Fund") and RA Capital Nexus Fund, L.P. (the "Nexus 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. The Adviser, the Adviser GP, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of any of the reported securities, except to the extent of their pecuniary interest therein.

F3: Under Mr. Scheiner's arrangement with the Adviser, Mr. Scheiner holds the option for the benefit of the Fund and the Nexus Fund. Mr. Scheiner 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 and the Nexus Fund to the Adviser. The Reporting Persons therefore disclaim beneficial ownership of the option and underlying common stock except to the extent of their pecuniary interest.
