(1) The stock option becomes vested and exercisable with respect to 1/48th of the shares each month after the vesting commencement date of September 5, 2012, subject to the Reporting Person's continuous service.
(2) The vesting of these Restricted Stock Units is subject to the satisfaction of time-based vesting and a performance-based condition. The time-based vesting occurs quarterly over four years from September 15, 2012, subject to the Reporting Person's continued service to the Issuer through each such vesting date. The performance-based condition will be satisfied if certain targets determined by the Issuer are met. If the performance-based vesting is achieved, then any Restricted Stock Units that had previously satisfied the time-based vesting shall become fully vested and any Restricted Stock Units that had not previously satisfied the time-based vesting shall become fully vested as such time-based vesting is satisfied.
