Explanation of responses
- F1All shares subject to the option vest 100% on the first to occur of (i) June 10, 2027 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).
- F2Under 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") and the RA Capital Nexus Fund, L.P. (the "Nexus Fund"). 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 and the Nexus Fund to the Adviser. The Reporting Person therefore disclaims beneficial ownership of the stock option and underlying common stock.
