The RSU vests in four installments of 1,250 shares each on the last day of each of the issuer's first, second, third and fourth quarters of fiscal 2010, provided the recipient continues to serve as a director of the issuer. The RSU vests only upon a change in the control of the issuer that occurs during the period beginning on the first day of the issuer's second quarter of fiscal 2010 and ending on the last day of the issuer's first quarter of fiscal 2015. The RSU is forfeited in the event the recipient ceases to be a director of the issuer for any reason other than a change in control prior to the RSU expiration date. by Sandra L. Lambert for John K.
