        <footnote id="F1">The purpose of this amendment is to correct the date exercisable of the warrants held by the reporting person included on Table II, Column 2, as reported on Form 3 filed on behalf of the reporting person on September 25, 2014. In that filing, the date exercisable of the warrant was incorrectly listed as January 2, 2013. The correct date exercisable for the warrants is May 3, 2013.</footnote>
        <footnote id="F2">The warrants are exercisable at a price of C$0.40. The US dollar price reported on this Form 3 in column 4 reflects the US dollar equivalent exercise price on the grant date, calculated at the closing price for cable transfers in Canadian dollars as reported by Yahoo Finance on such date of U.S.$1.00 =  CDN$0.9939.</footnote>
