                          ("Aminex" or "the Company")

Aminex announces that its statement of 22 April 2002, entitled BLOCKLISTING
APPLICATION, RNS number 8834U released at 15.05, contained an incorrect heading
and should have been entitled instead ADDITIONAL LISTING. The contents of the
original announcement are unaffected by this correction.


For the avoidance of doubt, the correct version of the announcement is set out
below:



                                  "AMINEX PLC
                          ("Aminex" or "the Company")

                               ADDITIONAL LISTING


Aminex advises that application has been made to both the London and Irish Stock
Exchanges and the UK Listing Authority for a total of 1,436,500 ordinary shares
of Eur0.06c each in the Company ("the Shares") to be admitted to the Official
Lists. It is expected that admission will be granted and that dealings will
commence, subject to allotment, on Thursday, 25 April 2002.


The Shares are being reserved under a block listing and will be issued as a
result of the exercise of share options pursuant to the following schemes:
