Explanation of Responses:

Id Content
F1 Represents shares of common stock earned upon the vesting of market stock units granted on June 17, 2022.
F2 The number of market stock units reported represents the maximum possible number of shares that are eligible for vesting, which is 225% of the number of shares that would be earned at target. The minimum payout factor that must be achieved to earn any payout is 60%. The actual number of shares that will vest on each vesting date will be determined by comparing the price of common stock on the applicable vesting date to the price of common stock on April 29, 2022 (i.e., number of vested shares is equal to (i) the number of shares at target payout multiplied by (ii) (a) the average price of common stock for the 10 trading days immediately preceding the applicable vesting date divided by (b) the closing stock price on April 29, 2022).
F3 The market stock units vest 25% on May 2, 2023 and in equal installments every three months thereafter over a three year period, subject to continued employment.
