<FN>
(1)      Fully dilutive effect of stock options and warrants on per share amounts for the year ended December 31, 1994 and 1992 were
         antidilutive.  Accordingly, fully diluted per share amounts were not presented in the Company's consolidated statements of 
         operations.

(2)      Fully dilutive effect of stock options and warrants on per share amounts for the year ended December 31, 1993 has not 
         been presented in the statement of operations since any reduction of less than 3% in the aggregate need not be considered 
         as dilution.
