On March 4, 2021, the Reporting Person was granted a performance-based restricted stock unit award ("PSU") under the Exelixis, Inc. 2017 Equity Incentive Plan covering 64,150 shares of common stock (such shares, the "Target Shares"). The PSU generally vests as follows: (i) 50% of the eligible Target Shares vest upon the Compensation Committee's (the "Committee") certification of achievement of certain performance criteria; and (ii) 50% of the eligible Target Shares vest on the first quarterly PSU vesting date (i.e. February 15th, May 15th, August 15th and November 15th) following the one-year anniversary of the Committee's certification. In addition, the PSU provides for vesting of up to a maximum of 200% of the Target Shares depending on the timing and level of achievement of the performance criteria provided for under the PSU.; On January 11, 2024, the Committee determined that certain performance criteria had been achieved, resulting in the Reporting Person's eligibility to vest up to 125% of the Target Shares subject to the PSU (such shares, the "Achieved Shares"). Accordingly, the Committee's certification on January 11, 2024 resulted in the immediate vesting of 50% of the Achieved Shares, and 50% of the Achieved Shares will vest on February 15, 2025, subject to the Reporting Person's continuous service through that date.; Includes 247,140 shares of Exelixis, Inc. common stock that will be issued to the Reporting Person upon vesting of restricted stock units.
