           *   For the calculation of loss per share, the inclusion of the
assumed exercise of options and warrants is not dilutive for the periods
presented and, therefore, such assumed exercise is excluded from the per share
calculations.

          **   The fully diluted loss per share is anti-dilutive and is,
therefore, not presented in the Consolidated Statements of Operations.
