Explanation of Responses:

( 1 )These securities are restricted stock units. Each unit represents the Reporting Person's right to receive one share of common stock. These restricted stock units shall vest at the rate of 1/4th of the shares subject to such restricted stock units as of the first anniversary of the vesting commencement date and 1/4th of the shares subject to such restricted stock units as of each of the subsequent anniversaries of the vesting commencement date thereafter, assuming continued service with the Company on each vesting date. For the purposes of the restricted stock unit grants, the vesting commencement date is 2/1/2012. ( 2 )All trades occurred within the price range of $44.02 and $44.16. The reported price is the weighted average for trades within this range. ( 3 )These shares were withheld by the Company as required for related tax liability in connection with the vesting of restricted stock units granted in prior years. This amount is amended and restated to correct an error in the amount previously reported in the original Form 4. ( 4 )Certain of these securities are restricted stock units. Each unit represents the Reporting Person's right to receive one share of Common Stock, subject to the applicable vesting schedule. This amount is amended and restated to correct an error in the amount previously reported in the original Form 4. ( 5 )These options are exercisable at the rate of 1/48th of the shares subject to such options on each monthly anniversary of the vesting commencement date. Such options shall have a term of seven years from the date of grant. ( 6 )Each restricted stock unit represents a contingent right to receive one share of common stock. ( 7 )This performance-based restricted stock unit ("PSRU") award is eligible to vest as follows: (1) 50% of the award is eligible to vest upon achievement of certain performance criteria based on total revenues, and (2) 50% of the award is eligible to vest upon achievement of certain performance criteria based on non-GAAP operating income. The actual PRSU award earned will vest as to 1/4th of the shares on each anniversary of the original grant date. The number of shares reflected is at the target award amount. No PRSUs will be earned below the target level of performance. At or above the target level of performance, the actual number of shares may range from 100% to 150% of the target award amount.
