The Merger Agreement also provides that, at the Effective Time, by virtue of the Merger:

(i) each Company Stock Option that is outstanding and unexercised immediately prior to the Effective Time, whether vested or unvested, will be canceled as of immediately prior to, and contingent upon, the Effective Time (without regard to the exercise price of such Company Stock Option) in exchange for the right to receive a lump-sum cash payment, less applicable tax withholdings, equal to the amount of the Option Consideration, if any, with respect to such Company Stock Option, except, that, if the per-share exercise price of any such Company Stock Option is equal to or greater than the Per Share Amount, such Company Stock Option will be canceled and terminated without any cash payment being made in respect thereof; and

(ii) each Company RSU that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be canceled as of immediately prior to, and contingent upon, the Effective Time in exchange for the right to receive a lump-sum cash payment, less applicable tax withholdings, equal to the Per Share Amount multiplied by the aggregate number of Shares subject to such Company RSU immediately before the Effective Time; and

(iii) each Company PSU that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be canceled as of immediately prior to, and contingent upon, the Effective Time in exchange for the right to receive a lump-sum cash payment, less applicable tax withholdings, equal to the Per Share Amount multiplied by the aggregate number of Shares subject to such Company PSU immediately before the Effective Time (with any performance-based goals deemed to be achieved and satisfied at 100%).

The Company also made customary representations and warranties in the Merger Agreement and agreed to customary covenants regarding the operation of the business of the Company and its subsidiaries prior to the consummation of the Merger.
