With respect to perf.-based RSUs, if the continued service requirement is satisfied and achievement of the perf. goal (x) exceeds 100% of target, Issuer may issue additional vested shares of common stock in an amount that corresponds to the incremental percentage of the perf. goal achieved in excess of 100% of target or (y) is less than 100% of target, the reporting person will surrender to Issuer shares of common stock in an amount that corresponds to the incremental percentage of the perf. goal achieved that is below 100% of target.
