Item 3.02.        Unregistered Sales of Equity Securities.

     On June 30, 2005 the Company  completed an exchange of its 15% Exchangeable
Convertible  Promissory  Notes  (the  "Bridge  Notes) and the right to be issued
warrants (the "Bridge Warrants") in connection with the Bridge Notes and held by
institutional and other accredited  investors ("Note holders").  In exchange for
the Bridge  Notes,  under which an aggregate  of  $6,693,027  in  principal  and
interest was owed, the Company issued  4,462,018  units at $1.50 per unit;  each
unit is comprised of one share of newly issued  common stock and three  separate
types of warrants to purchase a total of 2.75 shares of common stock as follows:
a Series A Warrant for 1.25 shares with an exercise price of $2.00 which expires
on the later of January 25, 2006 or five months after the registration statement
referred to below is declared  effective;  a Series B Warrant for  one-half of a
share with an exercise  price of $2.90 which  expires on the later of  September
25,  2006 or 12 months  after the  registration  statement  referred to below is
declared effective;  and a Series C Warrant for one share with an exercise price
of $4.00 that expires on May 25, 2010. In addition,  1,232,997  shares of Common
Stock were issued in consideration for the surrender of the rights to the Bridge
Warrants  held by the  Note  holders.  The  units  were  issued  pursuant  to an
exemption  from  registration  under Rule 506 of Regulation D. All of the Bridge
Notes and Bridge Warrants were exchanged so that none are now outstanding.
