This completes the financing previously announced by Plaintree on December 21, 2001. The Financing, which was completed in two separate tranches on December 28, 2001 and January 8, 2002, received conditional regulatory approval on December 21, 2001. Each Unit is comprised of one (1) common share of Plaintree (each a "Common Share") and one warrant (each a "Warrant"). Each Warrant entitles the holder to acquire one Common Share at an exercise price of $0.51 per Common Share for a period of three years from the closing date on which the related Warrant was issued. The Financing was completed by Plaintree without the use of an agent and Plaintree has not undertaken to qualify any of the securities being offered pursuant to the Financing.
