Footnotes

F1: This security represents restricted stock units (the "RSUs") granted under the Issuer's 2015 Equity Incentive Plan, as amended. Each RSU represents a contingent right to receive one share of common stock of the Issuer.

F2: These RSUs shall vest in five (5) equal annual installments beginning on May 15, 2022, such that the RSUs shall be fully vested on May 15, 2026, subject to the Reporting Person's continued service with the Issuer through each such date.

F3: Represents the number of shares required to be sold by the Reporting Person to cover the tax withholding obligation in connection with the settlement of vested RSUs. This sale is mandated by the Issuer's election under its equity incentive plans to require the Reporting Person to fund this tax withholding obligation by completing a "sell to cover" transaction with a brokerage firm designated by the Issuer. This sale does not represent a discretionary trade by the Reporting Person.

F4: This option shall vest and become exercisable in sixty (60) equal monthly installments on the 1st day of each calendar month beginning on June 1, 2021, subject to the Reporting Person's continued service with the Issuer through each such date.
