Footnotes

F1: The shares underlying the option are fully vested and immediately exercisable.

F2: On September 27, 2021, the reporting person filed a Form 4/A which inadvertently understated the remaining number of options available for exercise under this stock option by 7,275 shares. This Form 4 corrects the error caused by such understatement in Column 9 of Table II by increasing the total amount of derivative securities subject to this stock option by such 7,275 shares.
