• Conversion of Initial Principal: The conversion of the initial principal amount of the Convertible Debenture (US$25,000,000) resulted in the issuance of 88,962,500 Units, consisting of 88,962,500 Common Shares and 44,481,250 Warrants, at a conversion price of C$0.40 per Unit. Each Warrant issued in respect of the conversion of the initial principal had an exercise price of C$0.46 per Common Share.

Each Warrant issued in respect of the conversion of Interest has an exercise price of C$1.68 per Common Share.
  
  

Glencore Canada has elected to exercise, on a cashless basis, all 44,481,250 Warrants issued pursuant to the conversion of the initial principal amount of the Convertible Debenture, at an exercise price of C$0.46 per Common Share, resulting in the issuance of an aggregate of 32,301,860 Common Shares to Glencore Canada (the "Warrant Exercise").
