               o  DDCFL is to serve as the financial  and  nominated  advisor to
                  the Company,  and ultimately to the PLC,  defined  below.  The
                  nominated advisor provides compliance  oversight and acts as a
                  regulatory arm of the London Stock Exchange.

               o  DDT, a division of Dawnay, Day Brokers Limited, is to serve as
                  the broker to the PLC, defined below.

               o  The Company  organized a registered  Public Limited Company in
                  the United  Kingdom  which is  expected  to change its name to
                  Turbotec  Products PLC ("PLC").  PLC is planned to acquire all
                  of the  common  stock of the  Company's  US-based  subsidiary,
                  Turbotec Products, Inc.

               o  PLC is to apply for  admission to trading on the AIM Market of
                  the London Stock Exchange in conjunction  with a share placing
                  of the ordinary shares of the PLC.

               o  Approximately $3.5 million,  net of expenses,  are anticipated
                  to be raised by DDT  through the  placing or  subscription  of
                  original  issue  new  ordinary  shares  of the  PLC to  United
                  Kingdom persons.

               o  Approximately $3.5 million,  net of expenses,  are anticipated
                  to be raised by DDT  through  the  placing or sale of ordinary
                  shares of the PLC to be sold by the Company to United  Kingdom
                  persons.

               o  Thereafter,  it is  anticipated  that the Company  will retain
                  approximately 60% of the then issued shares of the PLC.

               o  DDCFL and DDT will be paid out of the proceeds of the offering
                  following:

                     o  Six (6%) percent  commission  on the value of the shares
                        placed at the placing price by the Company and the PLC.

                     o  A fee of (pound)120,000 by the PLC.

                     o  Reasonable expenses by the PLC.

               o  Following  admission on AIM,  DDCFL will act as the  nominated
                  advisor and DDT will act as broker to the PLC.

               o  The Company, the PLC, DDCFL and DDT will, immediately prior to
                  admission to AIM, enter into a placing agreement,  a nominated
                  advisor agreement, and a broker agreement.

               o  DDCFL and DDT are to be  appointed  for a minimum of 12 months
                  subject to certain  exceptions  specified  in the  Appointment
                  Agreement.
