for a period of 24 months. Twenty-five percent of the gross proceeds, net of
agents fees and expenses, have been deposited in escrow. In the event that the
Company does not obtain a receipt for a prospectus qualifying the distribution
of common shares and warrants upon exercise of the Special Units prior to
January 29, 2002, such proceeds will be used by the Company to repurchase up to
twenty-five percent of the Special Units, if holders so elect.

The warrants and the common shares issuable upon exercise of the Special Units

may not be offered or sold in the United States absent registration or
