Computational note:

         In connection with the computations for 1996, all common share
         equivalents have been excluded because their impact on the Company's
         net loss per share is antidilutive.  In connection with the
         computations for 1995, the Company has included the effect of dilutive
         stock options and warrants pursuant to the rules of Securities and
         Exchange Commission.
