(1)      Fully dilutive effect of stock options and warrants on per share
         amounts for the year ended December 31, 1994 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 years ended December 31, 1993 and 1995 have not been
         presented in the statement of operations since any reduction of less
         than 3% in the aggregate need not be considered as dilution.
