HOW TO COMPLETE THIS PROXY FORM

Your Name and Address

This is your name and address as it appears on the company’s share register. If this information is incorrect, please make the correction on the form. Shareholders sponsored by a broker should advise their broker of any changes. Please note: you cannot change ownership of your shares using this form.

Appointment of a Proxy

If you wish to appoint the Chairman of the Meeting as your proxy, mark the box in Step 1. If the person you wish to appoint as your proxy is someone other than the Chairman of the Meeting please write the name of that person in Step 1. 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 shareholder of the company. A proxy may be an individual or a body corporate.

Votes on Items of Business – Proxy Appointment

You may direct your proxy how to vote by placing a mark in one of the boxes opposite each item of business. All your shares 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 shares you wish to vote in the appropriate box or boxes. If you do not mark any of the boxes on the items of business, 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.

Appointment of a Second Proxy

You are entitled to appoint up to two persons as proxies to attend the meeting and vote on a poll. If you wish to appoint a second proxy, an additional Proxy Form may be obtained by telephoning the company’s share registry or you may copy this form and return them both together.

To appoint a second proxy you must:

• (a) on each of the first Proxy Form and the second Proxy Form state the percentage of your voting rights or number of shares applicable to that form. If the appointments do not specify the percentage or number of votes that each proxy may exercise, each proxy may exercise half your votes. Fractions of votes will be disregarded.

• (b) return both forms together.

Individual: where the holding is in one name, the holder must sign.
