                          ("Aminex" or "the Company")



Following the Irish High Court's approval of Aminex's share capital reduction
announced on 29 April 2002, Aminex now confirms that the amount per Ordinary
share that each Aminex shareholder on the register at close of business on 29
April 2002 will receive is as follows:



In euros:             EURO 10.75 cents

                      (to Aminex shareholders with Irish registered
                      addresses)



In sterling:          Sterling 6.65 pence*

                      (to Aminex shareholders with United Kingdom or Channel 
                       Island addresses)



In US dollars:        US 9.7 cents

                      (to all other Aminex shareholders)



* The reason for the difference between this amount and the amount of 6.9p per
share published in the Company's circular of 13 February 2002 is the subsequent
strengthening of sterling against the dollar.



The following exchange rates have been applied:



US$1   :  EURO 0.9029
