Proxy Voting Rules and Guidelines

NOTICE AND ACCESS

The Canadian securities regulators have adopted rules which permit the use of notice-and-access for proxy solicitation instead of delivering printed copies of proxy materials to each shareholder.

Under notice-and-access, proxy materials will be available for viewing up to one (1) year from the date of posting and a paper copy of the materials can be requested at any time during this period.

Disclosure regarding each matter or group of matters to be voted on is in the information circular in the section with the same title as each Resolution found on the previous page. You should review the information circular before voting.

The Corporation has elected to utilize notice-and-access and provide you with the following information:
