Id	Content
F1	The sale reported on this Form 4 represents shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units. The sale occurred automatically to satisfy the tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the Reporting Person.
F2	Each restricted stock unit ("RSU") represents a contingent right to receive one share of Issuer common stock.
F3	25% of the shares underlying the RSUs vested on February 17, 2022, with the remainder vesting in equal quarterly installments over 3 years, subject to the Reporting Person's continuous service with the Issuer as of the applicable vesting date, and subject to accelerated vesting in specified circumstances.
