($1,000,000) as set forth in the Side Agreement. Capitalized terms used herein
but not otherwise defined shall have the meaning ascribed to them in the

          of 10% per annum from April 2, 2001 to the date hereof and (iii)
          Thirty One Thousand Dollars ($31,000) in advance (the "Deposit") for
          the legal fees and expenses (the "Expenses") incurred by e-celerator
          in connection with the negotiation and delivery and performance of
          its obligations under the Side Agreement. e-celerator agrees to
          provide a summary invoice of the Expenses promptly and (i) in the
          event that the actual Expenses incurred by e-celerator are less than
          the Deposit, e-celerator shall return promptly such excess amount to
          the Company and (ii) in the event that the actual Expenses incurred
          are in excess of the Deposit, the Company agrees to pay promptly
          e-celerator such additional Expenses not to exceed Four Thousand
          Dollars ($4,000).

     2.   e-celerator represents and warrants that the Securities are owned
          beneficially and of record by e-celerator free and clear of all
          liens, encumbrances, charges and assessments of any kind whatsoever,
          and upon payment of the aggregate purchase price by the Company to
          e-celerator and upon transfer to the Company of the Securities by
          e-celerator, the Company will receive title thereto free and clear of
          all liens, encumbrances, charges and assessments of any kind
          whatsoever.
