         On October 8, 2004, Sanofi-Aventis (formerly known as
Sanofi-Synthelabo) issued the following joint press release with Proctor &
Gamble.


                            



                              [SANOFI AVENTIS LOGO]


                                                          Paris, October 8, 2004

                   STRENGTHENING OF THE ALLIANCE ON ACTONEL(R)
                        BETWEEN THE SANOFI-AVENTIS GROUP
                              AND PROCTER & GAMBLE


The  Sanofi-aventis  Group and Procter & Gamble (P&G)  announced  that they have
signed  today  an  agreement  to  maintain  the   collaboration   on  Actonel(R)
(risedronate sodium tablets).

Sanofi-aventis  and P&G  believe  that this  agreement  will  enhance the global
market presence of Actonel(R). The alliance will continue to promote bone health
and disease  awareness  through  numerous  activities to support  physicians and
patients.  A  common  commitment  has  been  formalized  covering  research  and
development and commercial  efforts in support of Actonel(R).  In addition,  P&G
will  jointly  promote   Actonel(R)  with   Sanofi-aventis  in  some  additional
territories.

Actonel(R) is a third-generation bisphosphonate indicated for the prevention and
treatment of osteoporosis in  postmenopausal  women. For the twelve month period
ending June 30, 2004, total global sales exceeded one billion  dollars,  up over
65% from  the  previous  year.  In  accordance  with  the  Alliance  agreements,
Sanofi-aventis  shares in Actonel(R)  results in all the  countries  where it is
commercialized.

Separately,  an option has been  granted to P&G  providing  the right to acquire
certain oral health care brands from  Sanofi-aventis  - namely the Fluocaril and
Parogencyl brands. The agreement makes it possible to preserve employment within
Sanofi-aventis,  thanks  to an  exclusive  supply  contract  entered  into  with
Sanofi-aventis for a 5 year period. This activity represented sales less than 55
millions euros in 2003.

FOR SANOFI-AVENTIS:  This press release contains  forward-looking  statements as
defined in the Private Securities Litigation Reform Act of 1995. Forward-looking
statements  are  statements  that are not  historical  facts.  These  statements
include  financial  projections and estimates and their underlying  assumptions,
statements  regarding plans,  objectives and expectations with respect to future
operations,  products and services, and statements regarding future performance.
Forward-looking  statements  are  generally  identified  by the words  "expect,"
"anticipates,"  "believes,"  "intends,"  "estimates"  and  similar  expressions.
Although Sanofi-aventis'  management believes that the expectations reflected in
such  forward-looking  statements are  reasonable,  investors are cautioned that
forward-looking  information  and  statements  are subject to various  risks and
uncertainties,  many of which are difficult to predict and generally  beyond the
control of  Sanofi-aventis,  that could cause actual results and developments to
differ  materially  from those  expressed  in, or implied or  projected  by, the
forward-looking  information  and  statements.  These  risks  and  uncertainties
include those discussed or identified in the public filings with the SEC and the
AMF  made  by   Sanofi-aventis   and  Aventis,   including  those  listed  under
"Forward-Looking  Statements"  and "Risk  Factors" in our annual  report on Form

law,  Sanofi-aventis  does not undertake any  obligation to update or revise any

this release,  are  forward-looking  statements,  as that term is defined in the
Private  Securities  Litigation Reform Act of 1995. In addition to the risks and
uncertainties noted in this release,  there are certain factors that could cause
actual  results  to differ  materially  from  those  anticipated  by some of the
statements  made.  These  include:  (1) the ability to achieve  business  plans,

volume profitably despite high levels of competitive  activity,  especially with
respect to the product categories and geographical markets (including developing
markets) in which the company has chosen to focus; (2)  successfully  executing,
managing and integrating key  acquisitions  (including the Domination and Profit
Transfer  Agreement  with  Wella);  (3) the ability to manage and  maintain  key
customer relationships; (4) the ability to maintain key manufacturing and supply
sources  (including  sole  supplier and plant  manufacturing  sources);  (5) the
ability to  successfully  manage  regulatory,  tax and legal matters  (including
product  liability  matters),  and to resolve  pending  matters  within  current
estimates;  (6) the ability to successfully implement,  achieve and sustain cost
improvement plans in manufacturing and overhead areas,  including the success of
the  company's  outsourcing  projects;  (7) the ability to  successfully  manage
currency  (including currency issues in volatile  countries),  interest rate and
certain commodity cost exposures; (8) the ability to manage the continued global
political  and/or  economic  uncertainty  and  disruptions,  especially  in  the
company's  significant  geographical  markets,  as well as any political  and/or
economic  uncertainty  and  disruptions  due to  terrorist  activities;  (9) the
ability to successfully  manage increases in the prices of raw materials used to
make the company's  products;  (10) the ability to stay close to consumers in an
era of  increased  media  fragmentation;  and  (11) the  ability  to stay on the
leading edge of innovation.  For additional  information concerning factors that
could cause actual  results to materially  differ from those  projected  herein,
