Of the shares underlying this RSU award, 34% shall vest on March 1, 2027 and the remainder shall vest in equal quarterly installments thereafter on each June 1, September 1, December 1 and March 1, so that all shares of common stock shall be vested as of March 1, 2029, subject to the reporting person's continuous service with the issuer as of each such vesting date.
