How to complete the Proxy Form

This is your address as it appears on the company’s share register.

A member may appoint the Chairman of the Meeting as your proxy, please complete as such. If the individual or body corporate you wish to appoint as your proxy is someone other than the Chairman of the Meeting please write the full name of that individual or body corporate in the space provided. If you leave this section blank, or your named proxy does not attend the meeting, the Chairman of the Meeting will be your proxy. A proxy need not be a security holder of the company. Do not write the name of the issuer company or the registered security holder in the space.

3. Votes on Items of Business

You may direct your proxy how to vote by placing a mark in one of the three boxes under each item of business. All your securities will be voted in accordance with such a direction unless you indicate only a portion of voting rights are to be voted on any item by inserting the percentage or number of securities you wish to vote in the appropriate box or boxes. If you do not mark any of the boxes on a given item, your proxy may vote as he or she chooses. If you mark more than one box on an item your vote on that item will be invalid.

It is the Chairman’s intention to vote for each of the Resolutions on the Proxy form.
