Ineligible shareholders A Shareholder who has a registered address outside Australia, New Zealand, Germany and the United Kingdom (Ineligible Shareholder) will not be eligible to participate in the Offers. You are not eligible to participate in the Offers and you will not be sent a copy of the Prospectus. This decision has been made pursuant to Listing Rule 7.7.1(a) of the ASX Listing Rules after taking into consideration the costs of complying with legal and regulatory requirements in jurisdictions outside of Australia, New Zealand, Germany and the United Kingdom compared with the small number of Ineligible Shareholders and the number and value of Shares and Attaching Options to which they would otherwise be entitled. The Company has appointed the Underwriter (Nominee) as nominee pursuant to ASX Listing Rule 7.7 to sell the rights to subscribe for Shares pursuant to the Prospectus (Entitlements) to which Ineligible Shareholders are entitled. The Nominee will have the absolute and sole discretion to 1 determine the timing and price at which the Entitlements may be sold and the manner of any such sale. Any interest earned on the proceeds of the sale of these Entitlements will firstly be applied against expenses of such sale, including brokerage, and any balance will accrue to Ineligible Shareholders. The net proceeds of the sale of these Entitlements will then be forwarded by the Company as soon as practicable to the Ineligible Shareholders, in proportion to their share of such Entitlements (after deducting brokerage commission and other expenses). If any such net proceeds of sale are less than the reasonable costs that would be incurred by the Company for distributing those proceeds, such proceeds may be retained by the Company. Notwithstanding that the Nominee may sell Entitlements, Ineligible Shareholders may nevertheless receive no net proceeds if the costs of the sale are greater than the sale proceeds. There is no guarantee that the Nominee will be able to sell Entitlements of Ineligible Shareholders on ASX and Ineligible Shareholders may receive no value for the Entitlements. Both the Company and the Nominee take no responsibility for the outcome of the sale of such Entitlements or the failure to sell such Entitlements. Important notice to nominees and custodians: Nominees and custodians should not forward this letter or any materials relating to the Entitlement Offer to any person with a registered address outside of Australia, New Zealand, Germany or the United Kingdom. If you have any questions, you should seek advice from your stockbroker, accountant or other independent professional adviser or call the Offer Information Line on 1300 850 505 (within Australia) or +61 3 9415 4000 (outside of Australia) at any time between 8:30am to 5:00pm (AEST) Monday to Friday.
