Restricted Stock Unit Awards (Performance Vesting)

In April 2013, the Compensation Committee approved the grant of restricted stock unit awards (performance vesting) for 129,000 shares of common stock to our executive officers that also contained both time-based and performance-based vesting terms (the “FY2014 Performance RSUs”). The aggregate estimated grant date fair value of the FY2014 Performance RSUs was $5.5 million, or $42.43 per share, based on the closing market price of our common stock on the date of grant. The FY2014 Performance RSUs vest only if both of the following criteria are satisfied: (1) our consolidated income from operations for the fiscal year ending March 31, 2014, as certified by the Compensation Committee, is in excess of the applicable target amount set forth in the table below; and (2) the recipient remains in the Service of the Company (as defined in our Equity Incentive Plan) until the applicable vesting date set forth below:

Shares Issuable Upon Settlement of FY2014 Performance RSUs	Consolidated Income from Operations for the Year Ending March 31, 2014	Vesting Date
25%	> 90% of target	April 29, 2016
25%	> 90% of target	April 29, 2017
25%	> 100% of target	April 29, 2016
25%	> 100% of target	April 29, 2017

(1) The weighted average grant date fair value of restricted stock units is based on the number of shares and the closing market price of our common stock on the date of grant.

(2) Nonvested shares at March 31, 2013 include only the FY2013 Performance RSUs that were deemed granted in accordance with ASC 718-10-55-95.

(3) The number of restricted stock units vested includes shares that we withheld on behalf of our employees to satisfy the statutory tax withholding requirements.
