The Company hereby grants to the Participant, effective as of the Date of Grant, a Restricted Stock Unit Award equal to [●] ([●]) RSUs, which RSUs shall be subject to time-based vesting (the “Time-Based RSUs”), on the terms and conditions set forth in the Plan and this Agreement. Each Time-Based RSU shall entitle the Participant to receive one share of Common Stock at such future date or dates and subject to such terms and conditions as set forth in this Agreement.

(b)

Events in Connection with a Change of Control. If there is a Change of Control and either (i) the Participant’s Service with the Company or its Subsidiaries is terminated without Cause following such Change of Control or (ii) the Time-Based RSUs are not assumed or replaced with an award of substantially equivalent value, the Time-Based RSUs shall fully vest (the date of vesting shall be a Vesting Date).

(c)

Termination of Service Other Than For Poor Performance, For Cause, death, Disability, or By Reason of Voluntary Resignation. The Time-Based RSUs shall fully vest upon the Participant’s termination of Service with the Company or its Subsidiaries for any reason (the date of such termination shall be a Vesting Date) other than a termination of Service for Poor Performance (as defined below), for Cause (as defined below), death, Disability, or by reason of voluntary resignation.
