On March 7, 2003, Hawker entered into an agreement (the “Financing Agreement”) with David Tuer and 970183 Alberta Ltd. (“FinanceCo”), as nominee for Matco Capital and David Tuer, pursuant to which FinanceCo agreed to purchase units (“Units”), subject to the satisfaction of certain conditions, from Hawker, with each Unit consisting of (i) a Hawker debenture, (ii) a warrant to acquire Common Shares and Class A Shares of Hawker and (iii) shares of two classes of preferred stock of Hawker. None of the debentures, Class A Shares or preferred shares are convertible or exchangeable into Common Shares. The warrants were not exercisable until a final prospectus relating to a proposed public offering of Common Shares by Hawker was filed with the Alberta, Canada securities authority. On April 3, 2003, Hawker issued the Units to FinanceCo. On May 30, 2003, the warrants were deemed to have been exercised as a result of the filing of a final prospectus relating to a public offering of Common Shares by Hawker and, as a result of such exercise, FinanceCo, as nominee for Mr. Tuer acquired 590,466 Common Shares and FinanceCo, as nominee for Matco Capital, acquired 1,180,934 Common Shares.
