Re:       Letter of Westbury Consultancy Services Ltd. received
          February 27, 2001, respecting the cancellation of the
          Warrant Agreement, its Addendum and related Warrant

          common stock underlying such Warrant of Sanguine
          Corporation ("Sanguine")

Dear Dr. Copellat:

          Thank you for the above reference letter terminating our Warrant
Agreement, as amended, and the Warrant.  We are sorry that your services could
not be provided to us.

          We hereby accept your letter, release you from any further
obligations under the Warrant Agreement as amended, and have canceled the
Warrant.  We would appreciate your forwarding the originally signed Warrant
dated March 20, 2000, for our records.

          We have engaged counsel to amend the SB-2 Registration Statement
to remove these shares as "registered ."

          We hope you remaining investment in Sanguine is very beneficial to
you.

          Thank you.

                                   Sincerely,
