(4)	On February 6, 2017, the reporting person was granted 10,000 RSUs, vesting in three equal installments beginning on the first market trading day following the first anniversary of March 6, 2017 (the "RSU Vesting Commencement Date") and 1/3 of the RSUs vest annually each year on the first market trading day after the second and third anniversary of the RSU Vesting Commencement Date.
