The exercise of the Over-Allotment Option may result in additional gross proceeds of up to US$82,528,500.

The Common Shares are offered by way of a short form prospectus filed in all of the provinces of Canada, excluding Quebec, and are offered in the United States pursuant to a registration statement on Form F-10 filed under the Canada/U.S. multijurisdictional disclosure system, and on a private placement basis in certain jurisdictions outside Canada and the United States pursuant to applicable prospectus exemptions.

No securities regulatory authority has either approved or disapproved of the contents of this news release.
