to the following allottees:

(a)       DH Newton Nominees Pty Limited (20,000 Ordinary Shares); and

(b)       ND & NL Birrell (20,000 Ordinary Shares).

The 40,000 Ordinary Shares of 50p were issued as a result of the exercise by DH
Newton Nominees Pty Limited and ND & NL Birrell of options granted to DH Newton
Nominees Pty Limited and ND & NL Birrell on 23 June 2005 to subscribe each for
20,000 Ordinary Shares of 50p at a price of 50p per share.

The 40,000 Ordinary Shares of 50p rank pari passu in all respects with the
Ordinary Shares of 50p already admitted to trading and will be admitted to
trading on 4 November 2005.



DH Newton Nominees Pty Limited is currently subject to a Lock-in Agreement
whereby DH Newton Nominees Pty Limited has undertaken, subject to certain
limited exceptions, not to dispose of any of the Ordinary Shares in the Company
which it holds, prior to 18 July 2006 (the first anniversary of the Company's
admission to AIM) without the prior written consent of Collins Stewart, the
Nominated Adviser of the Company.  Further orderly marketing arrangements apply
to the period commencing on 18 July 2006 and ending 18 July 2007, pursuant to
which DH Newton Nominees Pty Limited is obliged to sell any Ordinary Shares in
the Company, which it chooses to dispose of, through Collins Stewart (or such
other broker as is appointed by the company from time to time).



The 20,000 Ordinary Shares allotted to ND & NL Birrell are not subject to any
lock-in or orderly marketing agreement.
