(1)	Includes 3,321 shares of Common Stock, 1,548 shares underlying restricted stock units and 264 shares of deferred stock which may be subject in whole or in part to vesting schedules tied to the reporting person's continued service with the issuer and will be distributed as actual shares of Common Stock of the issuer either at the time of vesting or at a specified time thereafter (including termination of service with the issuer).
(2)	Includes 3,121 shares of Common Stock, 1,548 shares underlying restricted stock units and 264 shares of deferred stock which may be subject in whole or in part to vesting schedules tied to the reporting person's continued service with the issuer and will be distributed as actual shares of Common Stock of the issuer either at the time of vesting or at a specified time thereafter (including termination of service with the issuer).
(3)	The Stock options are exercisable according to the vesting schedule. The shares vest in four successive equal annual installments upon Ms. Yip's completion of each year of service with the issuer over a four-year period measured from the April 29, 2003 issue date of the stock options.
