Instruction for Completion of CDI Voting Instruction Form

Your Address

This is your address as it appears on the company's Securities register. If this information is incorrect, please mark the box and make the correction on the form. Securityholders sponsored by a broker (in which case your reference number overleaf will commence with an 'x') should advise your broker of any changes. Please note, you cannot change ownership of your securities using this form.

Your vote is important

Each CHESS Depositary Interest (CDI) is equivalent to one share of Company Common Stock, so that every 1 (one) CDI that you own as at end of trading day on Wednesday, 27 April 2022 (Australian Eastern Standard Time) (record date) entitles you to one vote.

You can vote by completing, signing and returning your CDI Voting Instruction Form. The CDI Voting Instruction Form gives your voting instructions to CHESS Depositary Nominees Pty Ltd, which will vote the underlying shares on your behalf. You need to return your completed CDI Voting Instruction Form so that it is received at the address shown on the Form no later than 5.00pm on Monday, 6 June 2022 (Australian Eastern Standard Time). That will give CHESS Depositary Nominees Pty Ltd enough time to tabulate all CHESS Depositary Interest votes and to vote the underlying shares.

Election of Directors and Appointment of Auditors

In accordance with applicable Canadian corporate and securities laws, a form of proxy (and consequently, a voting instruction form) sent to securityholders of a reporting issuer must provide an option for the securityholder to specify that the securities subject to the form must be voted or withheld from voting in respect of the appointment of an auditor or the election of directors. Accordingly, this CDI Voting Instruction Form provides voting "For" or "Withhold" (which is the equivalent to "Abstain") with respect to the appointment of an auditor and the election of directors.

Signature(s) of CHESS Depositary Interest Holders

Each holder must sign this form. If your CDIs are held in joint names, all holders must sign in the boxes. If you are signing as an Attorney, then the Power of Attorney must have been noted by the Company's Australian Registry or a certified copy of it must accompany this form.

Only duly authorised officer/s can sign on behalf of a company. Please sign in the boxes provided, which state the office held by the signatory, ie. Sole Director and Sole Company Secretary, two Directors or Director and Company Secretary.

If you require further information on how to complete the CDI Voting Instruction Form, telephone the Registry on (within Australia) 1300 850 505 or (outside Australia) [phone].
