Explanation of Responses:
1. Each restricted stock unit represents a contingent right to receive one share of Common Stock.
2. The Compensation Committee of the Company's Board of Directors determined vesting as of August 12, 2013 at 135% of the original grant amount for fiscal 2013 performance-based restricted stock units awarded August 12, 2012. Such determination was based on the Company's level of achievement of revenue and non-GAAP operating income targets established by the Company's Board of Directors. Disclosure hereunder represents a recalculation of the number of shares previously reported on a Form 4 filed August 13, 2012.
3. Restricked Stock Units have no expiration date.
4. One fourth (1/4) of these performance-based restricted stock units vest August 12, 2013. See Note 2. The remaining three-quarters (3/4) of the performance-based restricted stock units vest twenty-five percent (25%) annually on each of August 12, 2014, August 12, 2015 and August 12, 2016.
