Explanation of Responses:

( 1 )Each restricted stock unit ("RSU") represents a conditional right to receive one share of common stock of the issuer. Dividend equivalents in the form of additional RSUs ("Additional RSUs") accrue with respect to RSUs (and any Additional RSUs previously accrued) when dividends are paid on shares of common stock of the issuer. ( 2 )The RSUs and Additional RSUs vest in equal increments on the first three anniversaries of the date of grant and convert into an equivalent number of shares of common stock of the issuer. Upon vesting, all fractional shares underlying the vesting tranche of RSUs and Additional RSUs are cancelled.
