Appendix 3Y

Dear Shareholder,

Enclosed herewith is an Appendix 3Y relating to recent trading activity undertaken by Transocean Securities Pty Ltd (“Transocean”), a company associated with our Chairman, Mr James Henderson.

In February 2011 Transocean exercised approximately 39.8 million 6.5 cent options, subscribing for approximately 39.8 million ADO shares representing a subscription amount of approximately $2.6 million which contributed significantly to the financial security that Anteo currently enjoys.

You will be aware that recently Transocean have sold a large proportion of these shares issued. I have discussed these selling volumes with Mr Henderson, and I am pleased to inform the market that Transocean has indicated that on-market selling in relation to this option exercise is now substantially complete.

Mr Henderson re-iterated that he has always been, and remains a strong supporter of the Company and has expressed great confidence in our present strategy and future commercial prospects.

Yours sincerely,

Dr G J Cumming Chief Executive Officer
