For purchasers of QC FT Shares resident in the Province of Québec, 10% of the amount of CEE will be eligible for inclusion in the deductible "exploration base relating to certain Québec exploration expenses" and 10% of the amount of the expenses will be eligible for inclusion in the deductible "exploration base relating to certain Québec surface mining exploration expenses" (as such terms are defined in the Taxation Act (Québec), respectively) giving rise to an additional 20% deduction for Québec tax purposes.
