TO VOTE BY COMPLETING THE VOTING FORM

The voting form can be used to either vote directly (Section 1) OR appoint a proxy to vote on your behalf (Section 2).

SECTION 1: DIRECT VOTING

If you wish to vote directly, you should clearly mark the box in Section 1 and the boxes in Section 3 to indicate your voting instruction for each resolution. Please only mark either “for” or “against” for each resolution. Do not mark the “abstain” box if you are voting directly. If no direction is given on a resolution, or if you complete both the boxes in Section 1 and 2, your vote may be passed to the Chairman of the Meeting as your proxy. Securityholders, custodians and nominees may identify on the Voting Form the total number of votes in each of the categories “for” and “against” and their votes will be valid. The Chairman’s decision as to whether a direct vote is valid is final and conclusive.

SECTION 2: APPOINTMENT OF PROXY

Indicate who you want to appoint as your Proxy.

If you wish to appoint the Chairman of the Meeting as your proxy, mark the box in Section 2. If you wish to appoint someone other than the Chairman of the Meeting as your proxy please write the full name of that individual or body corporate. If you leave this section blank, or your named proxy does not attend the meeting or does not vote on a poll in accordance with your instructions, the Chairman of the Meeting will be your proxy by default. A proxy need not be a Securityholder of the company. Do not write the name of the issuer company or the registered Securityholder in the space.

Appointment of a Second Proxy

You are entitled to appoint up to two 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 contacting the company’s securities registry or you may copy this form.

To appoint a second proxy you must:

(a) complete two forms. On each form state the percentage of your voting rights or the number of securities 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 in the same envelope.

SECTION 3: VOTING DIRECTIONS

To cast your direct vote or to direct your proxy how to vote, place a mark in one of the boxes opposite each resolution. All your securities will be voted in accordance with such a direction unless you indicate only a portion of securities are to be voted on any resolution by inserting the percentage or number that you wish to vote in the appropriate box or boxes. The sum of the votes cast must not exceed your voting entitlement or 100%. If you do not mark any of the boxes on a given resolution, your proxy may vote as he or she chooses (subject to any voting restrictions that apply to your proxy). If you mark more than one box on a resolution for all your securities your vote on that resolution will be invalid.

Proxy which is a Body Corporate

Where a body corporate is appointed as your proxy, the representative of that body corporate attending the Meeting must have provided an “Appointment of Corporate Representative” prior to admission. An Appointment of Corporate Representative form can be obtained from the company’s securities registry.

SECTION 4: SIGN THE FORM

The form must be signed as follows:

Individual: This form is to be signed by the Securityholder.
