Factors that may cause such differences include, but are not limited to: the outcome of the SEC Staff discussions and any potential SEC inquiry, the impact of the implementation of new accounting pronouncements and interpretations, the status of and any actions in connection with the management cease trade order; rules and pronouncements of foreign jurisdictions and their interpretation by foreign courts, tribunals, regulatory and similar bodies; as well as the risk factors discussed in the Company’s most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, filed with the SEC and the Canadian Securities Administrators (“CSA”), as well as other periodic reports filed with the SEC and the CSA. Readers should not place undue reliance on any such forward-looking statements, which speak only as of the date they are made. Except as otherwise required by law, the Company disclaims any obligation to publicly update or revise any such statement to reflect any change in its expectations or in events, conditions, or circumstances on which any such statements may be based, or that may affect the likelihood that actual results will differ from those contained in the forward-looking statements.
