         o        Stoller Ingenieurtechik GmbH

Eurotech, Ltd Suirte 200, 1216 16th Street Washington, DC 20026 U.S.A.

         Cancellation of Cooperation Agreement among Stoller Ingenieutechnik
         GmbH, Forschungszentrum Karlsruhe GmbH, Forschungszentrum Julich GmbH
         and Eurotech Ltd dated 02/12/12/03/12/17/1999

Dear Ladies and Gentlemen:

In the above-cited Cooperation Agreement, your company undertook certain
obligations which you have not fulfilled despite frequent written and oral
requests. After three postponements, the delivery of EKOR material did not take
place and the collaboration on the part of the Russians never came to pass
despite many attempts on the part of the project management to make contact with
them. Even the time schedules established by you for the delivery of materials
have not been complied with, so that there is no longer a dependable basis for
the cooperation that is necessary for the entire project.

We hereby cancel indefinitely the above-referenced Cooperation Agreement in
accordance with section 13.2 thereof. You are not entitled to results pursuant
to section 7 because no results could be achieved.

Best regards
