Footnotes

F1: Each restricted stock unit ("RSU") represents a contingent right to receive one share of Issuer common stock.

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: On February 20, 2020, 25% of the shares underlying the RSUs granted on February 20, 2019 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 acceleration in specified circumstances.
