Explanation of Responses:

( 1 )Represents the shares required to satisfy tax withholding obligations in connection with the vesting of 110,966 restricted stock units("RSUs"). ( 2 )Each RSU represents a contingent right to receive one share of the common stock. All unvested RSUs will automatically expire upon Reporting Person's termination of service from Issuer. ( 3 )50% of the shares underlying the restricted stock unit award vested on the first anniversary date of the original grant date of the award, and the remaining 50% of the shares vested on the secondary anniversary of the original grant date. The number of shares reported reflect additional shares issued to the reporting person based on the difference of the closing price of Issuer's common stock on the original grant date and the second anniversary date of the original grant date. ( 4 )Pursuant to the original terms and conditions of the restricted stock unit award, if the aggregate market value of the total number of shares issued as of the second anniversary of the original grant date, together with the aggregate market value of any shares underlying this award that have previously been sold before such date, is less than the aggregate market value of the total number of shares issuable under this award as of the original grant date (in each case, as measured by reference to the closing market prices of the Issuer's common stock on said dates), then the reporting person will receive additional fully vested shares on such second anniversary date with an aggregate market value (measured by reference to the closing market price of the Issuer's common stock on such date) equal to the difference between the two amounts.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
