The U.S. dollar equivalent of the maximum aggregate offering price has been calculated using an exchange rate of US$1.00 = C$1.4095 which was the daily exchange rate as published by the Bank of Canada on July 21, 2026 (being a date within five business days prior to the filing of the initial Registration Statement). In accordance with Rule 416 under the Securities Act, this registration statement shall be deemed to cover an indeterminate number of additional shares to be offered or issued from stock splits, stock dividends or similar transactions with respect to the shares being registered.&lt;br/&gt;&lt;br/&gt;Estimated solely for the purpose of calculating the registration fee. Pursuant to Rule 457(o) under the Securities Act, the aggregate maximum offering price of all securities issued by the Registrant pursuant to this registration statement from the assumed exercise of all subscription rights will not exceed US$407,946,080.17. No separate registration fee is payable with respect to the rights. Pursuant to Rule 457(g) under the Securities Act, the registration fee for the rights is determined on the basis of the offering price of the securities issuable upon exercise thereof. Accordingly, the registration fee attributable to the rights is included in the fee calculated for the common shares set forth in the table above.&lt;br/&gt;&lt;br/&gt;This registration statement relates to the common shares issuable upon the exercise of transferable subscription rights pursuant to the rights offering.</ffd:OfferingNote>
