In addition, the Company has agreed to accelerate the vesting of Mr. Prevost&#x2019;s outstanding time- and performance-based restricted stock unit and stock option awards, with the portion of performance-based restricted stock unit awards for which the performance period has not been completed vesting assuming target performance is achieved.
