Explanation of Responses:
Remarks:
This Form 4/A amends and restates the original Form 4 filed on November 3, 2021 (the "Original Form 4") to reflect (i) the hybrid settlement of the portion of the restricted stock unit award vested on the Vesting Date, rather than the all-share settlement of such portion inadvertently reported in the Original Form 4, and (ii) the Reporting Person's previously reported new address.
