  ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.
  
       On April 15, 2005, the Company and Dialog4 System Engineering GmbH entered
  into an agreement whereby all disputes between them have been settled.  As was
  discussed in prior periodic reports filed by the Company with the Securities and
  Exchange Commission, the disputes arose in connection with the Asset Purchase
  Agreement between the Company and Dialog4, pursuant to which the Company in
  January 2002 purchased assets of Dialog4. We have paid to Dialog4 $490,000 at
  the time the settlement papers were signed and will pay an additional $475,000
  one year after the settlement date (i.e., on or before April 15, 2006). The
  Company also agreed to file with the SEC a registration statement under the
  Securities Act of 1934 by June 30, 2005. The registration statement will cover
  any sales by Dialog4 of the 1,250,000 shares of common stock which we issued to
  Dialog4 on January 18, 2002 as partial payment of the purchase price of assets
  we bought.

       As part of the settlement, the Company resolved a separate employment
  dispute that had been under litigation in Germany between Berthold
  Burkhardtsmaier and the Company. Mr. Burkhardtsmaier agreed to resign from the
  Board of Directors for the Company; the Company agreed to pay him approximately
  324,000 Euros in monthly installments of 5,400 Euros for 60 months.
  
       Dialog4 dismissed the Arizona litigation without prejudice and when all the
  terms and conditions of the settlement agreement have been met Dialog4 and the
  Company will release each other from any further claims arising out of or
  related to the Asset Purchase Agreement.

  Burkhardtsmaier resigned from the Board of Directors on April 15, 2004,
  effective immediately.
