Explanation of Responses:

Id	Content
F1	These shares were acquired under the Issuer's Employee Stock Purchase Plan in transactions that were exempt under both Rule 16b-3(d) and Rule 16b-3(c).
F2	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.
F3	Each restricted stock unit ("RSU") represents a contingent right to receive one share of Issuer common stock.
F4	On February 19, 2021, 25% of the shares underlying the RSUs granted on February 19, 2020 vested, and the remainder vest in equal quarterly installments over three 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.
