Risk factors that could cause actual results or events to differ materially from current expectations include, among others, failure to obtain the shareholder approvals, failure to satisfy all closing conditions for the private placement and the failure to satisfy all of the release conditions of the bought deal public offering pursuant to the subscription receipt agreement, failure to obtain necessary regulatory or stock exchange approvals, and delays in completing the private placement or the bought deal public offering, the failure to enter into definitive agreements with respect to the debt package with lenders, on the terms and conditions previously announced and/or set forth in the commitment letter (including the amount of the facilities) or at all, the completion of due diligence by EDC and CIB, the failure of the Company to meet the Facilities’ conditions precedent and/or customary closing conditions and the expected impacts of the facilities on the Company’s operational and financial situation and general economic conditions, as well as earnings, capital expenditure, cash flow and capital structure risks and general business risks.

Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements are provided for the purpose of providing information about management’s expectations and plans relating to the future.
