Any participation in the LIFE Offering by insiders constitutes a “related party transaction” as defined under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“ MI 61-101 ”).

The Company is relying on the exemption set forth in Section 602.1 of the TSX Company Manual in connection with the LIFE Offering, which provides that the TSX will not apply certain standards to certain transactions involving eligible interlisted issuers on a recognized exchange.

The TSX has conditionally approved the LIFE Offering. Final approval of the LIFE Offering by the TSX remains subject to the completion of customary conditions by the Company. This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities.
