     herewith the Subscriber has subscribed for 500,000 Shares.

(C)  The Company intends to apply for the admission ("Admission") to the trading
     system operated by the European Association of Securities Dealers Automated
     Quotation NV/SA ("EASDAQ") of 14,464,654 Shares consisting of the whole of

          enforcement of creditors' rights generally and (b) equitable
          principles limiting the availability of equitable remedies, All

          convertible securities or other agreements or commitments to issue, or
          contracts or any other agreements obligating the Company to issue any
          shares of any class or kind, or securities convertible into shares;

     4.5. neither the execution of this Agreement nor the consummation of the
          transactions contemplated herein will conflict with, violate or result
          in a breach or constitute a default (or an event which, with notice or
          lapse of time or both, would constitute a default), or result in the
          termination of, or accelerate the performance required by, or result
          in the creation of any lien or encumbrance upon any of the assets of
          the Company under, any provision of any memorandum, articles of
          association, indenture, mortgage, lien, lease, agreement, contract,
          instrument, or any other restriction of any kind or character to which

          effect; and

     4.7. the unaudited pro forma opening balance sheet of the Company as at 31
          December 1998 which has been provided to Subscriber, fairly represents
          the financial position of the Company as of that date and the Company
          has no liabilities (whether absolute, actual, contingent or otherwise)
          as at 31 December 1998 which were required to be reflected in and
          disclosed in such balance sheet in accordance with UK GAAP and which
          were not so reflected.

     Agreement shall terminate without liability to either party.
