APPENDIX 3Y – MR ANDREW TSANG

Pursuant to the Listing Rule 3.19A.2, the Company (entity) is required to notify the ASX of a change to a notifiable interest of a director of the entity by lodging an Appendix 3Y no more than 5 business days after the change occurs.

Due to a breakdown in internal communications over the past two weeks, relevant information which was provided to the Company within the required 5 business days involving further changes to Mr Andrew Tsang’s director’s interests were not recorded and accordingly advised to ASX within time.

Herein attached is an Appendix 3Y for Mr Andrew Tsang which provides details of his “direct” and “indirect’ shareholding changes over the period 5 May 2009 to 7 May 2009.

The Company apologises for this breach of the Listing Rule in question and will implement action to avoid a reoccurrence, including assistance from the Company’s Share Registry to monitor changes. The Company continues to regularly liaise with directors so that notifiable interests are released to market in a timely manner and that directors remain aware of the Company’s disclosure responsibilities under ASX Listing Rule 3.19B.

Yours faithfully
