*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(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)	The stock option vests and becomes exercisable in three equal annul 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.
