(1) Each Restricted Stock Unit ("RSU") represents the right to receive one share of the issuer's common stock. The RSU vests in three equal annual installations beginning on March 10, 2012, provided that the issuer meets certain performance requirements for fiscal 2011 and the reporting person is employed by the issuer on the vesting date. The maximum number of shares the reporting person may receive is 150% of the RSU amount.
(2) This stock option vests and becomes exercisable in three equal annual installments beginning on March 9, 2012, provided the reporting person is employed by the issuer on the vesting date.
(3) The shares represent the partial settlement under a RSU award granted 3/3/2010. One-third of the RSU vested on 3/10/2011 and was converted to vested common stock on a one-for-one basis on the vesting date.
