Notes:

1.   Represents shares issuable upon exercise of outstanding stock options.
     Shares were calculated using the treasury stock method and average market
     values.

2.   Represents incremental shares issuable upon exercise of outstanding stock
     options. The additional shares were calculated using the higher of the end
     of period or average market value.

3.   This calculation is submitted in accordance with Regulation S-K Item
     601(b)(11) although it is not required by footnote 2 to paragraph 14 of APB
     Opinion No. 15 because it results in dilution of less than 3%.
