If the Performance Goal is met prior to the first Vesting Date, then all four annual installments will vest in accordance with the vesting schedule. If the Performance Goal is met subsequent to the first Vesting Date, each annual installment relating to a Vesting Date that has already occurred will automatically vest upon achievement of the Performance Goal and any remaining installments will vest in accordance with the vesting schedule. If the Performance Goal is not met by June 1, 2022, all stock options are forfeited.</footnote>
