A document comprising Listing Particulars in relation to the issue of 13,461,538
New Ordinary Shares in connection with the Acquisition of Tanzoil NL, as
announced on 12 February, 2002, has been published by the Company.


Accordingly, application has been made to the Irish Stock Exchange and to the UK
Listing Authority for 13,461,538 New Ordinary Shares of nominal value €0.06 each
in the capital of Aminex to be admitted to the Official List of the UK Listing
Authority and to the Official List of the Irish Stock Exchange ("the Official
Lists") and application has been made to the Irish Stock Exchange and the London
Stock Exchange for these shares to be admitted to their respective markets for
listed securities. It is expected that admission to the Official Lists will
become effective and that unconditional dealings will commence on 28 March,

These new Ordinary Shares will, on issue, rank pari passu with the existing
Ordinary Shares save that they will not be entitled to participate in the return
