(1)    Amount represents the number of shares issued assuming exercise of stock
       options, reduced by the number of shares which could have been 
       purchased with the proceeds from the exercise of such options.

(2)    Amount represents the number of common shares issued assuming exercise 
       of warrants outstanding.
