One-third (1/3) of the RSUs will vest on each of the first, second and third anniversaries of the grant, subject to the Reporting Person continuing to be a Service Provider through each vesting date. This transaction is not a sale of shares by the Reporting Person. Instead, this represents shares that have been withheld by the Issuer to satisfy its income tax and withholding and remittance obligations in connection with the vesting and net settlement of previously reported restricted stock units. /s/ Elizabeth Villalobos, Attorney-in-Fact for Josh D.
