Step 2: Make Your Payment

You can exercise your options utilising the payment options detailed overleaf.

By making your payment you confirm that you agree to all of the terms and conditions of the Options.

Choose one of the payment methods shown below.

By Mail: Complete the reverse side of this payment slip and detach and return with your payment. Make your cheque, money order or bank draft payable in Australian dollars to "Duxton Water Limited". The cheque must be drawn from an Australian bank. Cash is not accepted.

Payment will be processed on the day of receipt and as such, sufficient cleared funds must be held in your account as cheques received may not be re-presented and may result in your Application being rejected. Paperclip (do not staple) your cheque(s) to the slip. Receipts will not be forwarded. Funds cannot be debited directly from your account.

Entering your contact details is not compulsory, but will assist us if we need to contact you.

BPAY ®: See overleaf. Do not return the slip with BPAY payment. Applicants should be aware that their own financial institution may implement earlier cut off times with regards to electronic payment, and should therefore take this into consideration when making payment. Ensure you have read and accurately followed your banking institution’s BPAY FAQ or other instructions prior to making multiple payments for multiple holdings under this offer.

Neither Computershare Investor Services Pty Limited nor Duxton Water Limited accepts any responsibility for loss incurred through incorrectly completed BPAY payments. It is the responsibility of the applicant to ensure that funds submitted through BPAY are received by this time.
