Explanation of Responses:

1. Restricted Stock Units ("RSUs") represent a contingent right to receive one share of the Issuer's common stock per RSU. RSUs have associated dividend equivalent rights ("DERs") that vest and become payable in shares of the Issuer's common stock proportionately with the RSUs to which they relate. Upon vesting of RSUs, the number of shares issuable under the associated DERs becomes calculable, based on the quotient of the accrued dividends with respect to the vested RSUs, divided by the common stock's fair market value on such vesting date (or in the event dividends are declared, but not yet paid to stockholders as of a vesting date, on the date of payment to stockholders).

2. These RSUs vest in full on the date shown, subject to the reporting person's continued service to the Issuer through the vesting date.
