(1) The option vests in 20% annual installments on each of the first five anniversaries of the grant date.
(2) Each restricted stock unit (RSU) represents the right to receive, at settlement, one share of common stock.
(3) The vesting of these performance-based restricted stock units ("PRSU") is dependent upon the achievement by Stericycle,Inc. of certain financial performance criteria. Subject to continued employment through the applicable vesting date and to accelerated vesting in certain circumstances, one-third (1/3) of the target number of PRSUs is scheduled to vest annually on each anniversary of the grant date following each of the 2018, 2019 and 2020 annual performance periods. Each year, the number of units that actually vest will be 0% to 100% of the scheduled amount, depending on the extent to which Stericycle, Inc. meets certain financial performance goals.
(4) The RSUs vest in 20% annual installments on each of the first five anniversaries of the grant date. All unvested RSUs are subject to continued employment through the applicable vesting date.
