Explanation of Responses:

Id	Content
F1	Each Restricted Stock Unit ("RSU") represents a contingent right to receive one share of the Issuer's Common Stock.
F2	The sale of shares was effected in order to satisfy tax withholding and remittance obligations in connection with the vesting of RSUs in compliance with Rule 10b5-1.
F3	On March 27, 2020, the Reporting Person was granted RSUs which vest in three tranches upon the Reporting Person achieving certain milestones relating to a combination of the passage of time and the Issuer's stock price. On December 4, 2021, the Issuer's Board of Directors determined that the milestone for the third tranche was satisfied, resulting in the vesting of the reported shares of common stock under the RSUs.
