Voting – non-registered shareholders

Non-registered, or beneficial, shareholders receiving these materials through their broker or other intermediary or service provider should complete and return the voting instruction form or pre-signed proxy form provided to them by their broker or other intermediary in accordance with the instructions provided therein, or otherwise follow the instructions provided by their broker or other intermediary or service provider.

A non-registered shareholder may revoke a pre-signed proxy form or voting instruction form given to their broker or other intermediary or other service provider by contacting the broker or intermediary or other service provider through which the non-registered shareholder’s common shares are held and by following the instructions of the broker, intermediary or other service provider respecting the revocation of proxies. In order to ensure that the broker or intermediary or other service provider acts upon a revocation of a proxy or voting instruction form, the written notice should be received by the broker or intermediary or service provider far enough ahead of the Meeting so the broker or intermediary or other service provider can act on your revocation or changed instructions in time for the Meeting.
