Subject: Rescission of Purchase of Common Stock in Mercosur Telephone & Telegraph Co., Inc. (Delaware) by Randolph S. Hudson

      On May 10, 2005, Financial Technology Research Corporation, a Colorado corporation ("Fintek"), and I entered into and executed that certain common stock purchase agreement (the "Stock Purchase Agreement"), a copy of which is attached hereto as Exhibit "1", and, by this reference, made a part hereof; together with my execution and delivery of that certain Stock Purchase Agreement, I executed a facsimile form of a temporary promissory note, of even date with the Stock Purchase Agreement, and a form of a pledge and security agreement, also of even date with the Stock Purchase Agreement.

      Due to Fintek's default under the terms of the Stock Purchase Agreement, I now desire to rescind the Stock Purchase Agreement and revoke the terms and conditions set forth therein and release my interest in the shares of stock (the "Mercosur Stock") in Mercosur Telephone & Telegraph Co., Inc., a Delaware corporation ("Mercosur"), that may have been transferred to me pursuant to the terms of the Stock Purchase Agreement. Moreover, as the result of my rescission of the Stock Purchase Agreement,

      Therefore, as the result of my rescission of the Stock Purchase Agreement, and by my action to void the Note and that certain pledge and security agreement, PLEASE TAKE NOTICE:

1.I hereby rescind and deem null and void the Stock Purchase Agreement, to become effective immediately, and state that all of the terms, conditions, covenants, and representations and warranties contained in said Stock Purc
