(1)	100% of these Time RSUs may vest on February 19, 2022.
(2)	Each RSU is issued pursuant to the Company's 2013 Long-Term Incentive Plan and represents a contingent right to receive one share of common stock, and vesting (i.e., forfeiture restriction termination) generally is subject to (i) the reporting person remaining an employee or director of the Company or its affiliates and (ii) the other criteria described in the footnotes herein.
(3)	0% to 150% of these Relative TSR Performance RSUs may vest on February 19, 2022 based on the Company's annualized total stockholder return ("TSR") performance ranking ("TSR Rank") relative to the constituent companies of the Standard & Poor's 500 Index for the three-year period ending December 31, 2021.
