Subject to certain continued employment conditions and subject to accelerated vesting in certain circumstances, the number of units that actually vest at the end of the three-year performance period will be 0% to 250% of the scheduled amount, depending on the extent to which the Issuer meets or exceeds certain performance goals at the end of each year during the performance period. The maximum number of units that may vest at the end of the three-year performance period is 6,315 (250% of the target number).
