Mr M Piccini Adviser, Listings Perth ASX Compliance Pty Limited Level 8 Exchange Plaza 2 The Esplanade Perth WA 6000

Dear Mauro,

We refer to our letter released to the ASX earlier today in which we notified option holders that their listed Catalpa options with an exercise price of $1.10 and expiry of 31 October 2011 ( Options ) were due to expire. The letter incorrectly stated that the quotation of the Options will end on 31 October 2011. The correct date on which quotation of the Options will end is actually 24 October 2011.

There is no change to the last date on which the options can be exercised which remains 31 October 2011.

Yours faithfully
