Explanation of Responses:

Id Content
F1 The sales reported on this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person.
F2 The option was fully vested and exercisable.
F3 Due to an administrative error, the reporting person's previous Form 4 filed on March 13, 2023 reflected an incorrect amount of zero for number of derivative securities beneficially owned following reported transaction(s) in Column 9 rather than 22,500. This filing corrects that error.
