SCRUTINEER

The figures reported by Computershare in its capacity as Scrutineerrepresent our tabulation of proxies returned to us by registered securityholders and, if Computershare has mailed voting instruction forms(VIFs) directly to non-objecting beneficial owners (NOBOs) on behalf of the issuer, VIFs returned directly to us by NOBOs, combined withcumulative reports of beneficial holder voting compiled and submitted by one or more third parties. As such, Computershare is only responsiblefor, and warrants the accuracy of our own tabulation of proxies and VIFs. Computershare is not responsible for and does not warrant theaccuracy of the cumulative reports of beneficial holder voting submitted by any third party.

If Computershare has mailed voting instruction forms directly toNOBOs on behalf of the issuer, these have been distributed on the basis of electronic files received by Computershare from intermediariesor their agents. Although Computershare reconciles these records to the Form 54-101F4 Omnibus Proxy delivered to us as required underNational Instrument 54-101, in some cases insufficient securities may be held within intermediary positions at The Canadian Depositoryfor Securities, Limited as at record date to support all securities represented. In these cases, if the situation cannot be rectified,over voting rules are applied as directed by the Chair.

Upon receipt of any cumulative reports of beneficial holdervoting compiled and submitted by one or more third parties, Computershare reviews the total votes received for each intermediary andreconciles the number to the position available to the intermediary on any omnibus proxy or supplemental omnibus proxy received. In theevent the intermediary’s position is insufficient to allow for the tabulation of the entire vote, Computershare may, but shallnot be required to, take steps to rectify the situation. In the event the situation is not rectified, over voting rules are applied asdirected by the Chair.

Acting on the direction of the Chair of the meeting, Computersharemay have included in our reports, the details of beneficial holders attending in person, whose ownership or previous voting status wecannot confirm or verify but whose identity may be supported by documentation, such as a VIF issued by a third party. In such cases, Computersharemakes no warranty or representation as to the accuracy of the numbers included as a result of the direction from the Chair, and assumesno liability or responsibility whatsoever for their inclusion in our report as Scrutineer.
