1)        The Common Stock  equivalents  consist of stock options,  warrants and
          the Series A Convertible  Preferred Stock.  Common  equivalent  shares
          from convertible  preferred stock (using the if- converted method) and
          stock options and warrants (using the treasury stock method) have been
          included in the computation  when dilutive  (except that,  pursuant to
          the Securities and Exchange Commission rules, the Series A Convertible
          Preferred  Stock which was  converted  into Common Stock in connection
          with the Company's initial public offering is included as if converted
          at  the  original  date  of  issuance  even  though  inclusion  may be
          anti-dilutive).  Pursuant to the  Securities  and Exchange  Commission
          Staff  Accounting  Bulletin  all common and common  equivalent  shares
          issued by the  Company at an exercise  price below the assumed  public
          offering  price during the  twelve-month  period prior to the offering
          have been included in the calculation as if they were  outstanding for
          the three months ended  September 30, 1995,  (using the treasury stock
          method and the initial public offering price of $12.00 Per share).
