- ----------
(1)  This number of Restricted Shares was calculated by dividing the value of
     the Participant's Restricted Share Award by the average closing price
     (rounded to two decimal places; so that the $23.115 average was rounded to
     $23.12) of a Share during the 20 trading days preceding February 15, 2002.
     The number of Restricted Shares so calculated was then rounded to the
     nearest whole Restricted Share; so that, for example, 14,273.356 Restricted
     Shares were rounded to 14,273 Restricted Shares.
