The shares underlying the option vest and become exercisable on the earlier of (i) May 22, 2026 or (ii) the Issuer's next annual meeting of stockholders following the grant date, in each case, subject to Mr. Resnick's continued service as a director through such date. | 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. Each of the Adviser, the Adviser GP, the Fund, the Nexus Fund, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of any of the reported securities, except to the extent of its or his respective pecuniary interest therein. | Under Mr. Resnick's arrangement with the Adviser, Mr. Resnick holds the option for the benefit of the Fund and the Nexus Fund. Mr. 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 and the Nexus Fund to the Adviser.
