American Depositary Shares.

A copy of the Prospectus Supplement and the Form are available from the rights agent, BNY Mellon, or by calling the information agent, Georgeson, Inc. at 800-2223-2064 (banks and broker-dealers) or 800-213-0473 (retail investors).

Beneficial owners are urged to consult their financial intermediary without delay to ensure the effective exercise of the rights.

Ordinary Shares. The ordinary shareholder subscription form is also attached to the April 3, 2013, Prospectus Supplement filed with the SEC as Appendix B.

Ordinary shareholders may also contact the Company's share registry, Security Transfer Registrars, 770 Canning Highway, Applecross, Western Australia 6153, telephone [phone].

Pricing The Offering has been priced in Australian currency and, as a consequence of the recent weakening of the Australian Dollar, the 2.5 Australian cents issue price for Ordinary Shares translates to a ADS price (representing 20 Ordinary Shares) of US$ 48 cents based on the exchange rate of 0.9612 published by the Reserve Bank of Australia (RBA) on May 23^rd. The actual ADS price will be determined by the exchange rate published by the RBA on June 10, 2013.
