                                           PRESS RELEASE - FOR IMMEDIATE RELEASE

               INYX SIGNS AN AGREEMENT IN PRINCIPLE TO ACQUIRE THE
              ASSETS & CERTAIN BUSINESS OF AVENTIS PHARMACEUTICALS
                                   PUERTO RICO

NEW  YORK  -  October  7,  2004  -  Inyx,  Inc.  (OTC  BB:  IYXI),  a  specialty
pharmaceutical  company  with a focus on niche drug  delivery  technologies  and
products,  announced  today that it has signed an agreement  in  principle  with
Aventis Pharmaceuticals, Inc., a wholly owned subsidiary of sanofi-aventis Group
(NYSE:   SNY),   to  acquire  the  assets  and   certain   business  of  Aventis
Pharmaceuticals Puerto Rico. The agreement in principle calls for execution of a
definitive  agreement  by December  15, 2004 and closing of the  acquisition  by
March 31, 2005.  Completion of the purchase will also be dependent  upon several
factors,   including  Inyx  completing  customary  due  diligence  and  securing
financing for the closing. Financial terms were not disclosed.

Jack Kachkar, M.D., Chairman and CEO of Inyx, said, "This acquisition would be a
major  milestone in the corporate  evolution of Inyx. It would greatly  increase
Inyx in operating size and scope.  It comes with several  multi-year  production
contracts and new business opportunities that would enable our operation of this
Puerto Rico complex to be profitable  from the start as well as provide a strong
catalyst  for future  growth.  The  Aventis  operations  in Manati,  Puerto Rico
consist of a high-calibre pharmaceuticals production center that would give Inyx
a strategic base in the United States to complement  Inyx's present  development
and manufacturing facilities located in the United Kingdom."

Dr.  Kachkar added,  "Manati gives Inyx a production  center on this side of the
Atlantic to better  serve the  marketplace  in the U.S. and Canada as well as in
Latin and South America,  which is an important catalyst for growing our base of
clients and industry partners as well as for introducing  Inyx's own proprietary
products. Moreover, Manati's facilities and employees are well suited for Inyx's
niche  aerosol  drug  delivery  technologies  and  products.  This  includes our
production  of   non-ozone-depleting   hydrofluoroalkane   (HFA)  gas  propelled
pharmaceutical products, enhanced single and combination drug inhalation-therapy
treatments, and hydrocarbon foam dermatology/topical formulations."

HFA is a primary substitute for the ozone-depleting chlorofluorocarbon (CFC) gas
propellant,  which is now banned in Canada, Europe and other countries, and soon
to be banned by most nations  around the world.  For  instance,  over 90% of the
asthma  inhalers sold in the United  States last year  contained  CFC,  which is
expected to be banned in pharmaceutical products by the U.S. during the next few
years. At the same time,  hydrocarbon  sprays are increasingly  replacing cream,
lotion  and  tablet  products  in  dermatological   and  certain  other  topical
applications,  because a foam or mousse  formulation  better penetrates the skin
and in turn  provides  faster  treatment  as well as does not leave  any  greasy
residue on skin and clothing compared with conventional ointments.

"Aventis  has  agreed  to sell the  Manati  complex  to Inyx  because  of Inyx's
expertise  in  the  production  of  aerosol  pharmaceuticals,  particularly  the
manufacture  of products  using HFA propelled and  hydrocarbon  delivery  modes.




Inyx's expertise  should ensure that Manati,  which no longer fits with Aventis'
core capacity needs, would continue to be a productive pharmaceutical center for
the  benefit of the site's  employees  and  customers  and the local  economy of
Puerto Rico," said Martin Siewert,  a senior executive in Industrial  Operations
for Aventis.

The Manati complex  consists of five buildings  totaling 139,157 square feet and
extending  over 9.5 acres,  located in north central Puerto Rico which is a life
sciences industry center about 30 miles outside of San Juan. Currently,  Aventis
employs  approximately  330 people at Manati,  and Inyx said it would  retain as
many of these experienced and skilled employees as economically feasible.
