Particulars of the Transaction

Under the terms of the Arrangement Agreement, holders of Beaufield Shares will be entitled to receive 0.0482 of a common share of Osisko in exchange for each Beaufield Share held immediately prior to the effective time of the Arrangement, representing an implied offer price of $0.082 per Beaufield Share based on Osisko’s closing price as of August 14, 2018 and a premium of approximately 54% based on the 20-day volume weighted average price of both companies’ common shares on the Toronto Stock Exchange and TSX Venture Exchange, as the case may be, on August 14, 2018 (being the last trading day prior to the announcement of the Arrangement).

Directors and officers of Beaufield and certain Beaufield Shareholders holding approximately 7.5% of the issued and outstanding Beaufield Shares have entered into voting and support agreements with Osisko in support of the Arrangement. The board of directors of Beaufield, on the recommendation of its independent special committee, has unanimously approved the Arrangement and will recommend that Beaufield Shareholders vote FOR the Arrangement.
