Conference Call                                                   sanofi-aventis


I.   INTRODUCTION

SANJAY GUPTA

Hello  everyone  and  welcome.  I would  like to begin,  since this is the first
conference  call for  sanofi-aventis,  by introducing  the new investors team at
sanofi-aventis.  I'm Sanjay GUPTA,  the new IRO. In my team in Paris, are Arnaud
Delephine,  and in New York it's Felix Lancher. Many of us know you and you know
us. We hope to have the  opportunity to see all of you in the coming  months.  I
would like to remind you that the slides for today's  call are  available on our
website: sanofi-aventis.com. This call is also being webcasted.

To comment on our performance we have with us today,  Hanspeter SPEK,  Executive
Vice President of  Pharmaceutical  Operations;  Mr. LEROY, the CFO; and Laurence
DEBROUX,   Deputy  CFO.  We  will  begin  with  some  introductory  comments  by
Jean-Claude,  followed  by a  business  update  by  Hanspeter,  and an update on
integration by Jean-Claude  again.  We will take questions later in the limit of
the time available. Jean-Claude?


II.  THIRD QUARTER OVERVIEW

JEAN-CLAUDE LEROY

Good  afternoon,  everybody.  Before I  begin,  I will  give you some  technical
comments because I feel that with this new  sanofi-aventis  venture,  we need to
give some  comments on the technical  matters.  Let me just give you a few words
about the business the way I see it. We're here to comment on rather solid third
quarter sales  numbers,  generally in line with the first half. I would say that
this is evidence of the momentum  that has been kept during the beginning of the
integration  process.  I guess that is very  important to us in the company,  as
well as it is to you as  investors,  to see that this  company is going on doing
well, whatever the events are.

To finish on that general comment,  I will just add that when I compare with the
information  that has been  released by our  competitors  it seems to be like it
points out so far that we are in a rather good position at the sales level.

Now, I will go back to follow up the slide  presentation and to give you some of
this technical information I was talking about.

So the first  information,  the date of the first  consolidation of Aventis into
sanofi-aventis will be 30 September 2004. What does that mean? I will talk about
sales but we will see later what it means for results.  First,  as you have seen
we've released also the consolidated  sanofi-aventis sales. As a matter of fact,
since  we're  consolidating  Aventis  as of 30  October,  it does  mean that the
sanofi-aventis   consolidated  numbers  do  represent  the  ex-,  the  old,  the
ex-Sanofi-Synthelabo  and only that.  So, we thought it would not be  meaningful
for the new Group and give a good view of the  performance.  So, we decided that
we would release also the pro forma sales on a comparable basis, and this is the
next slide which is on the pro forma combined sales. I know it's a bit technical
but we did  actually do this  together to define what we do mean,  what is under
this.


Paris, 21 October 2004                                                         2





Conference Call                                                   sanofi-aventis

The  pro  forma  combined   sales  is  to  measure  the  sales   performance  of
sanofi-aventis, we start including the former sales of Sanofi-Synthelabo for one
part and Aventis from the other part. But not that,  only that.  That reduced by
the sales of  products  which have been sold at the  request of the  competition
authorities - I'm talking about Arixtra(R),  Fraxiparine(R),  Campto(R). In each
sequence  whatever it is - third quarter 2004,  nine months 2004, the comparable
with 2003, third quarter,  nine months - these are the corresponding  figures of
sales for these products have been taken out of the comparison.  Again,  just to
point out when I was referring to the consolidated  sales of  sanofi-aventis  in
which you have  understood that  Arixtra(R) and  Fraxiparine(R)  are included in
this nine months  performance.  Arixtra(R) and  Fraxiparine(R)  up to the end of
August  because  the  divestment  occurred  at the end of  August.  So,  what is
important  is that we try to give you through  that pro forma  combined  sales a
good comparison to the sales  performance of the Group. In addition,  as you can
see, the Aventis Behring has been taken out.

So, that being said,  we decided also that the old concept of  Sanofi-Synthelabo
was to be kept for the new  sanofi-aventis  Group but we had to define  what was
the content of that. We took one  definition  which is to say that we would like
to report on the economic  performance  of,  obviously,  the pro forma  combined
sales plus the sales of the products which belong to sanofi-aventis.  That means
that as for the ex-perimeter of Sanofi-Synthelabo, we will include the worldwide
sales of these  products  which are in  partnership  with Bristol Myers Squib. I
mean obviously Plavix(R) and Avapro(R),  and the Myslee(R), the Japanese part of
the sales which are made through the JV with Fujisawa. That does mean that other
sales of very interesting products such as Actonel(R),  for example, will not be
reported  this way just  because  of the fact that this is not a  sanofi-aventis
product. This is the reason for the different classification.

Now, before giving the opportunity to Hanspeter to comment on the performance of
sales on the third quarter and nine months,  it's just to give you a few figures
to help you explain on that chart showing the pro forma combined sales.  You see
we've split the third  quarter and the nine months.  As you see,  we've made the
segmentation obvious:  pharmaceutical  activities and vaccines. This is going to
be our primary  segmentation for reporting  purposes from now on. In addition to
that,  these  figures  are  shown  on a  comparable  basis.  What  do we mean by
comparable basis in that instance? We do mean several things. First,  obviously,
this does not include the currency  impact.  As you see in the press release for
the first  quarter  sales,  on a global basis - I mean pharma plus vaccines - we
have a negative 4% impact on the third  quarter when we do show a 4.6%  negative
impact for nine months.

Now, some of you have read some reports  already on this and are wondering  what
it means as far as the  perimeter is  concerned.  As I said  before,  all of the
products that have been sold for  anti-trust  authorities  are excluded  totally
from any period in this comparison.  In addition to that, you will remember that
there were some products - and mainly  Admacord and Endolatryl - which were sold
by  Aventis  during the first part of the 2004  year.  Now,  obviously  they are
excluded from the comparison. If I were to give you the impact of these products
which have been sold, I would give you the following kind of information. As far
as the third quarter is concerned,  this would be reported as a 1.3% increase in
sales,  as well as it would show up as a 1.2%  negative  impact on a nine months
basis.  So, in turn,  you've seen that we have not used as  reported  concept of
these pro forma  combined  sales.  This is because so far we thought it would be
too much  figures,  but if some of you would like to make  reporting  of that on
this concept,  I would tell you that on the third quarter we would show up a 5.4
increase in sales on a so-called  reported basis. This would tell you that as of
the end of  September,  nine  months now,  we would show 4.7.  But now,  this is
something  that is  going  to be more  important  when at the end of the year we
describe  and comment  about the result.  


Paris, 21 October 2004                                                         3




Conference Call                                                   sanofi-aventis

As far as the sales are concerned, I guess that the comparable basis is the most
appropriate way of reporting on our sales. A quarter of 10.7, nine months +10.5.
I guess this is what we have to comment now in more detail with Hanspeter.


III. BUSINESS UPDATE

HANSPETER SPEK

Good morning, good afternoon. If you look at the first chart which is on page 8,
I hope you will agree that it is a very,  very nice picture to look to. So, it's
15 leading  products  of the new Group,  which  represent  approximately  62% of
overall sales. Out of the 15 products,  13 products show a high two digit growth
rate,  and  there  are only two  products  which  are  suffering.  First of all,
Allegra(R),  which is  suffering  from a weak  season in Japan and from the well
known issues in the US market. Second, of course, Tritace(R), which is suffering
from an out of  patents  situation  in  Europe.  There it is mainly  the  United
Kingdom and Germany where we have significant losses in value sales. But I think
it is worth  mentioning  that  through a very  pro-active  price  policy we have
managed to stabilise our value sales. In Germany, for example, it's close to 60%
because we pro-actively lowered our prices.

So on the fast growing major products,  what to say? More in detail,  Lovenox(R)
is doing  extremely  well, even stronger in the US. We of course hope to benefit
in  the  mid  and  near   future   from  the   circumstances   coming  from  the
non-registration  of the AstraZeneca  product,  which we have been watching very
closely.  We have then  Plavix(R).  Perhaps on first  glance  it's a little bit,
slightly lower growth rate in the quarter,  which is to my  understanding to the
largest extent possible a technical  effect.  We have a little decrease of stock
in the United  States.  We had an artefact  in the base of the third  quarter in
Germany,  where we had anticipated buying by launching a new peptide,  which was
[inaudible].  But if we look to the  prescription  rates  we see no  significant
changes in trends,  and we estimate a very  strong  fourth  quarter,  especially
coming from the US.

The Taxotere(R)  performance is varying.  We have a much stronger growth outside
the US. In the US, we are still  suffering from the  unfavourable  reimbursement
situation between Taxotere(R) and Taxol(R).  We are entirely confident that this
situation will change because the American citizen is going to change by the end
of this  year or very  early in 2005.  So we  consider  that  especially  on the
American  market,  2004 will be a year of  transition  and we expect very,  very
strong growth.  Also in the US, as from 2005, very much of course supported from
the new  indications  the  product  has  recently  obtained  in the US, but also
outside.

In the end, the trend is totally  stable and  unchanged.  We have a prescription
rate as of before,  fluctuating month by month between 12% and 14%. And what you
see is of course in addition to the given price increases.  Eloxatine(R): nearly
55% growth;  continued  strong growth in the US but also growth of approximately
35% outside the US, which shows that this product continues to grow nearly eight
years after its first launch, which has been done in France in point of fact.

I think  it's  worth  mentioning  that  the  smaller  products  like,let's  say,
Depakine(R)  a very old product but a gold  standard in the therapy of epilepsy,
for example,  is growing at nearly 11%. So overall,  for those products a growth
rate of 18.5% on a nine months  basis,  and you see it's exactly the same growth
rate  of  18.5%  for  the  third  quarter,  which  is for  us a very  confirming
indication that the trend of the businesses of the two businesses in stand alone
is not at all suffering from the ongoing


Paris, 21 October 2004                                                         4



Conference Call                                                   sanofi-aventis


integration,  which of course has been an important issue for us to watch and we
feel very much  confirmed  that we are not only putting not the business at risk
but we also  believe  that this  very,  very  positive  growth  is even  further
enhancing  our  ongoing  integration  because  our  people  get a very  positive
stimulation from it.

If you look then at page 9, you see that the Unites  States  continue  to be the
growth driver.  You see again that we had a very good third  quarter,  where the
growth  even  accelerated  to 18.3% as  compared  to 16.0%  for the year to date
figure.  You see further  that our  performance  in Europe is nearly on the same
level:  5.5 as  compared  to 6.5.  Last but not least,  the rest of the world is
nearly 9% as compared to 11%. We have a little bit of a seasonal  dip but,  once
again, the fourth quarter has started very, very promising.

So  overall  you see then that the third  quarter  has been  growing by 10.7% as
compared to 10.5% on a year to date basis.  I think it's  important to correlate
this with the overall  pharmaceutical market is growing slightly below 7%. So we
feel that the new Group before it has been really finally integrated has a very,
very good and promising  base to realise one of our major  objectives  for 2005,
which of course  will be to  continue  to grow  significantly  above the  market
average.


IV.  INTEGRATION UPDATE

JEAN-CLAUDE LEROY

OK, thank you Hanspeter. Going on now on the company, how we put it in shape for
that full  integration  in 2005.  Just a  reminder  - I know that all of you are
pretty aware of all of these events. If you take that, then you remember that we
took the keys of Aventis - sorry for saying that so directly but that's  exactly
the reality - sometime around 20 August.  When you see how the  organisation has
been put in place  inside the  company by  appointing  all the people who are to
lead the rest of the company. Hundreds of people have been nominated, or will be
in the very next days, in all the countries and regional organisations,  as well
as the central,  scientific,  industrial  and so on. We are very close to having
the new organisation  which is set up for leading the new company in these days.
That was what we wanted to do. We are in the process of doing it for having this
Company in good shape for doing  business on a new basis as of the  beginning of
the year.

Now, in addition to that, we have had some interesting  events to comment on, in
the integration process because this is part of it, as you've seen. There was an
existing  agreement  on  Actonel(R)  with  Procter  &  Gamble,  and we have  the
opportunity to negotiate or further negotiate this agreement in order to secure,
to keep,  the  co-management  of this  product  around the world with  Procter &
Gamble.  That has been negotiated to reinforce the product  sustainability,  the
flexibility around R&D and so on. We are very pleased to have the opportunity of
this reinforced collaboration of this very interesting product, which all of you
know has been doing over $1  billion in sales,  over the last 12 months  rolling
over. We are continuing the  collaboration on Alvesco(R) with Altana,  and there
is FDA action which is scheduled after the 23rd.

As far as Exubera(R) is concerned,  we said that we are  considering our action.
Where are we? I remember  there is a change in control  clause  attached to that
collaboration. Now, in the fact you may have seen that we are, I would say, in a
small  disagreement.  We've said that this  operation of buying  Aventis has not
triggered the clause.  They have said in Pfizer to the contrary.  So there is an
issue and we are waiting our actions. Well, that is just to tell you that we are
reviewing everything


Paris, 21 October 2004                                                         5



Conference Call                                                   sanofi-aventis


and beginning the discussion with Pfizer. I cannot give you any more conclusions
just because of the fact there is no difference  today with the situation  which
existed at the time of the operations. So more news to come in the future but so
far there is no more news to be given.

As well as in the  integration  process  to finish  with,  I mean this is only a
general  information  and I know that you would like to know more about that. We
are reviewing all of the  molecules,  the  portfolio,  as well as the commercial
organisation,  ongoing  on other  collaborations.  More news to come on that,  I
guess as we said, at the very beginning of next year, but be sure that we are on
it.

We said that we would  try to  simplify  our legal  chart in order to be able to
accelerate the restructuring of the Group.  That's what we've been doing. You've
seen that the merger  between the two companies - Aventis and  sanofi-aventis  -
has been  approved  by both the  Supervisory  Board of Aventis  and the Board of
Directors of  sanofi-aventis.  This project is going to be submitted to the AGM,
which is going to be held before the end of the year. So, at the end of the year
we will be in good shape on that.  I would add that we are also  Hoescht  German
side of the operation with the same goal.

What  are the  next  events,  I guess  this is also of  interest:  what  are the
forthcoming  events before the end of the year on a product basis, and there are
several  information  which you know.  The first  one,  as I already  said,  the
Alvesco(R)  action date at the FDA.  Beginning  of November the ten month action
date for  Eloxatine(R)  adjuvant  indication.  Acomplia(R)  presentation  at the
American Heart  Association at New Orleans of the results of the study RIO North
America,  an important event for our company.  I know that a lot of people would
like to know more about the  Plavix(R)  patent  situation.  The only event which
everybody  knows,  because this is very  official,  is the date of the pre-trial
order of Plavix(R) on 8 December.  As you know, we know no more about this. It's
not  difficult  to say that the trial might come some time at the  beginning  of
2005 but we don't know more for the time being.

Communication  on our figures.  We will have the next sales call probably before
the end of January 2005, on a full year 2005 figures,  again  consolidated,  pro
forma with  comparisons.  And obviously,  as you all expect, in very early March
and we will release not only the 2004 results,  but the business review, the R&D
portfolio  review,  which we  promised  we would do,  obviously  an  acquisition
synergies update,  and guidance for the year 2005. So I know that I'm not giving
you more  information  in that respect today but we are gearing up everything in
order to be able to deliver to you all this information at this date at the very
beginning of next year.


SANJAY GUPTA

Thank you Jean-Claude.  OK, are we ready for questions now?


V.   DISCUSSION


ANDY COLSON, REDBURN PARTNERS

First of all,  congratulations on the integration and your first set of numbers.
I've got a quick question on Rimonabant. I know there's been some uncertainty of
whether the RIO North  American  study will be  reporting  one or two year data.
Given that we're only a couple of weeks


Paris, 21 October 2004                                                         6




Conference Call                                                   sanofi-aventis


away is there any clarity on what's  going to be  presented  yet, or are we just
going to have to wait and see?


SANJAY GUPTA

I think  your  second  guess is the right  one:  just  wait and see.  We will be
presenting  results on 9 November;  it's not so far away.  The company  does not
want to tell you now; we have all the data at hand and we are evaluating at what
we can present. So I give you rendezvous on 9 November.


MORGAN STANLEY

Four quick questions if I may. First, to Hanspeter:  could you just give us some
sense of how the much larger  portfolio you now have at your disposal  given the
acquisition  translates  into  benefits  when  dealing  with  the  Managed  Care
authorities  both in terms of getting drugs on formerin and also  reimbursement.
Secondly, could you tell us in which line rebates are given, whether it's in the
revenue line or elsewhere?  Thirdly, inventory and pricing in the portfolio both
generally and for the outlying individual products. Finally, I see the pre-trial
order is set for 8 December.  Is there any risk to that date in itself, or is it
for sure that we're going to find out the schedule on the 8th?


HANSPETER SPEK

On the first,  Managed Care,  it's difficult to say. We are just starting to try
to build up a common Managed Care policy between Aventis and  Sanofi-Synthelabo,
and of  course  this  also has to be  coordinated  with  what  Bristol  Myers is
practising on the two joint venture  products:  Plavix(R) and  Avapro(R).  So, I
cannot give you very precise  estimates  and figures on it, but I can give you a
gut  feeling.  I think that there will be a certain  trend of,  yes,  the Sanofi
portfolio will get a broader access to Managed Care. But on the other side, this
will have a price. So, frankly, what I expect is nothing in terms of negative or
positive synergies, including on sales in the US, for being a much larger Group.
I think we have all reason to indicate that there is  continuing  pressure on US
prices.  So we will try to manage this to the best and, as I said,  for the time
being, I do not expect anything out of it.


JEAN-CLAUDE LEROY

As far as the rebates are  concerned,  I can confirm to you that the rebates are
taken  out of the  sales  that are  imported.  In other  words,  sales  that are
imported are net sales out of rebate.


Hanspeter SPEK

We have no price changes in the ongoing quarter, on the  Sanofi-Synthelabo  side
first of all.  Consequently,  I mean I can give you all the  stocks,  product by
product,  but believe me there is no  significant  changes.  All of the stock of
Sanofi  turns  between  0.5 and 0.6.  This is exactly the same for the stock for
Aventis  products,  where the stock varies  between 0.3 (which  currently is the
stock of Lantus(R))  and higher stock I see would be Anzemet(R)  with 0.6. Sales
data are  relatively  stable.  The average stock in Aventis today is 0.5, it has

Paris, 21 October 2004                                                         7

December  03 for  example,  it has been 0.4. So it is fair to say that the stock
levels  today on both  sides are more  than  reasonable,  approximately  half of
[inaudible].


SANJAY GUPTA

On the Plavix(R)  trial,  experience has taught us that dates that are scheduled
are not cast in stone.  So I would think that it's always possible for the dates
to slip.  We don't know anything more about it; it's what's there in the judge's
orders.  If the judge gets some other  priority he can change those  dates.  So,
that's the best indication we have but it's not 100% and it depends upon events,
on the judge's calendar.


ERIC LEGARDE, REAMENS

First  question  on  Actonel(R).  Could  you  tell us if,  beyond  what you said
already,  there is now with Procter & Gamble a less favourable  split in profits
for you? Second, on Exubera(R), if the judge is to rule in Pfizer's favour, what
does it mean?  What Pfizer wants?  Do they want to regain full rights or do they
want to change the agreement?  If you can be more precise.  Thirdly, out of this
quarter  and for the nine  months as well could you tell us how much  represents
the OTC business to be sold to Procter & Gamble,  and also the generic business,
as you more and more speak about this Winthrop activity.  Fourthly, just to give
us some  insight  about the  quality  and  feedback  you get from the  launch of
Ketek(R) in the US. The 41 million may seem pretty low. The final  question,  to
get an update on the flu vaccine situation in the US. What we may expect for the
fourth  quarter?  And also perhaps the kind of sense you may have from the US to
see higher number of competitors, perhaps, for the next season.


HANSPETER SPEK

I may start with Actonel(R). You see the spirit of the agreement we made remains
wholly  unchanged.  The spirit of the agreement has meant that there was a small
partner,  Procter & Gamble,  entering into an agreement with a relatively  large
partner,  Aventis, to develop this market. It was foreseen that Procter & Gamble
would get more and more actions within this deal. This spirit has been perfectly
maintained,  and what Procter will increase in terms of gains should be balanced
off by the overall very strong  increase in sales of this product.  Now, that is
the  intention;  how it comes is very  difficult  to  predict  today  because it
depends how the product penetrates  individual markets. You know that in certain
markets  sanofi-aventis will have the product  exclusively;  in other markets it
will be sharing the product;  and in other markets the product will be launching
by Procter solely.  So I think I cannot go much further.  Believe me, the spirit
of the  agreement  is exactly  maintained:  there is a rising share of Procter &
Gamble in this deal but this should be very well traded off by the fact that the
product has a very, very bright future for the years to come.

On the generic business, well the generic business today - according to the very
precise  definition  of  generic,  which  means  products  being  sold under the
international  non-proprietary name and being promoted through [inaudible] - our
business is small; it's about 300 million. Nevertheless, it is profitable. It is
of  course  not as  profitable  as the  prescription  business  but it has  very
significant two digit  profitability.  In terms of strategy, I would say an axis
which is two-fold. First of all, we have today a blockbuster product, which will
most likely lose all of the patents by age during the


Paris, 21 October 2004                                                         8



Conference Call                                                   sanofi-aventis


next 10 to 15 years, and we have today a policy in this respect which is that we
will no more give away volumes for those products. Which means that we'll have a
very  pro-active  stand in terms of price policy for many  reasons:  to keep our
patients on the medication,  to keep our factories full, and to continue to well
absorb overhead costs, and to avoid too much volatility in our performance.  The
second aspect in terms of generic policy is we feel that the N(degree)1  company
in Europe and the N(degree)3  company in the world has to make a strategic offer
to  health  care  providers  which is not  unilaterally  based  on high  priced,
innovative  products  but we  feel we need  also  to  have  an  opportunity  for
bargaining,  for making proposals on the other side, which is the low price side
of generics.  There are more and more health care providers and  governments who
expect to get proposals from international  pharmaceutical companies, and we are
ready to fill our role also in this respect.

Now, in terms of perspectives, it's clear that this business even if it will one
day reach its critical size - which we estimate at  approximately 1 billion - it
will still  remain a marginal  business  in respect of the  overall  size of the
company, and the impact on the multiples will consequently remain insignificant


JEAN-CLAUDE LEROY

In relation to Exubera(R), the question if I well remember is what Pfizer wants.
Well, I could say I don't know what Pfizer wants. The only thing which is a fact
is that Pfizer has  designated  a banker for  valuating  the  products.  So even
though we're not in agreement in the change in control  clause,  we've done also
the same for  valuation  purposes.  And I just can  remind you what might be the
consequences  at the end of the day  after the  valuation  has been done is that
Pfizer  decides  to buy  back  the  product  from  sanofi-aventis,  or they  ask
sanofi-aventis  to buy back the product,  or they decide to stay in the existing
alliance. It is their decision. Whatever is done, one way or the other, it would
be done on a market  value  basis.  For the rest I don't know more  about  their
intentions.

There was a question  about the part of the OTC  business.  The  value,  just to
remind  you,  the figures for 2003 on a yearly  basis,  the sales were  (euro)53
million. That's what we're talking about.


HANSPETER SPEK

On the OTC business,  let's be clear about this. What is supposed to be acquired
by Procter & Gamble is not our OTC business.  It is our dental business,  and it
has nothing to do with our pharmaceutical OTC business,  which of course will be
maintained also because OTC is an important strategic option.

Now on Ketek(R), it is very early to make any statements because the product has
been just  promoted  actively  since two months.  So, what we hear from  Managed
Care, for example,  is extremely positive - amazingly positive even. You can see
that we have very good access.  I can give you one other precise figure which is
that in September we have sales of 120 000  scripts,  which  amounts to a market
share of  approximately  2.3%. This means doubling the market share from August,
where it has been only 1.2%.  So, the figures or course are  ridiculously  small
but the trends are very promising.  Of course, we know that the real battle will
come up in the upcoming season of respiratory and pulmonary  infections.  So, we
will really know by the end of the first quarter where we stand.


Paris, 21 October 2004                                                         9



Conference Call                                                   sanofi-aventis


JEAN-CLAUDE LEROY

There was a last question  about flu vaccines.  I guess that this refers to what
you learned yesterday that the companies sanofi-aventis and Aventis Pasteur will
be  capable  of  delivering   an  additional   2.5  million  doses  in  the  US.
Unfortunately,  we will not be capable of delivering  globally more in the year,
just  because  the  process of  manufacturing  takes some time.  We cannot  just
replace the lack of production which is induced by the situation with Chiron. We
will do everything which we can do, the maximum,  but unfortunately we will have
reached  the top  with the  last  information  which  was  given  to the  market
yesterday.


LEHMANN BROS

A few product  related  questions  please.  Firstly,  could you update us on the
Lovenox(R)  motion for summary  judgement.  Any time line for a decision  there?
Secondly,  on Alvesco(R),  you talk about an action date. I think most of us are
assuming that  respiratory  products take longer than 12 months.  Do you believe
that we could  actually  see some action at this point or is it much more likely
that this is going to be rolled over for a little longer?  Could you give us the
US sales of  Xatral(R)  please?  You talk very  confidently  about a rebound  in
growth for Taxotere(R) when the  reimbursement  comes in. Are you confident that
the  prescriptions  for  taxines in total are still  rising at the 20% rate that
they were rising  before,  i.e. the increased  use of Taxol(R)  which will swing
back? Or is there  actually a shift away from the taxines to other products such
as Alimta(R). A final question on Ambien(R).  Could you just tell us how you are
getting ready?  Are you putting more effort behind this product in  anticipation
of competition early next year?


HANSPETER SPEK

Let me start  with the  Ambien(R)  question,  the  answer  is yes.  We will take
advantage of a united strike force of  sanofi-aventis,  7 600 reps in the US, as
of 1 January,  in anticipation of the upcoming launch or launches.  But we would
have done this even  without  those  launches  because  we feel that  there is a
direct  relation  between  promotion  and  sales of  Ambien(R),  and we know the
potential  of the  product by far has not been  leveraged.  On  Taxotere(R)  and
Taxol(R), what we expect for 2005 is a high two digit growth for Taxotere(R). It
is driven by the continued growth inside the existing  indications.  If you look
to the growth  which is evidence for  Taxol(R),  you see a high two digit growth
figure,  which means that Taxol(R) could benefit from the current  reimbursement
situation but also from an increased use of course. But our expectation for 2005
is of course  also driven by  additional  sales  coming from the newly  obtained
indication in prostate cancer.


LEHMANN BROS

Is high two digit more than 20 then?


HANSPETER SPEK

I would  say it starts  at least  with a 20.  We are in the  early  phase of the
budget so I cannot  give you a precise  figure  but,  yes, I  definitely  expect
something. If the reimbursement situation changes we


Paris, 21 October 2004                                                        10



Conference Call                                                   sanofi-aventis


have to get back to our 20%  growth,  which is also the  growth we see  outside,
where we don't have this artefact of the American current reimbursement system.


JEAN-CLAUDE LEROY

Alvesco(R):  we are  speculating.  We have an action based on what we say. We of
course  also see it may take  longer,  but of  course we hope we get a clear cut
action answer but this cannot be excluded that there is a request for additional
data,  as is always the case.  Of  course,  this is field of  indication  as you
correctly sate where very often additional  questions are being asked related to
dose or applications  and so forth because those products are a little difficult
perhaps in terms of development.


PHILIPPE

The Lovenox(R) summary judgement. You know that it is not unusual for motions of
summary  judgement  to be filed in such law  suits.  So now,  we have not  heard
anything  back  from the  judge,  who is going  to  decide  if he want to have a
hearing  or if he want to  consider  on the brief  alone.  So, we have not heard
anything back from him. We expect to hear something maybe by the end of the year
or the beginning of next year.


HANSPETER SPEK

US sales of  Xatral(R):  once again we are still not content with  developments,
which are much  slower  than  anticipated.  We have sold in the  fourth  quarter
between 4 and 5  million,  which is about half of what we had  expected.  So the
good news are,  nevertheless,  that we see in less than, let's say, four weeks a
very,  very nice - even sharp  increase - in  prescriptions.  We are on a weekly
basis now at 18% of prescriptions coming from neurologists for the market. Which
means we have 18% and  Flomax(R)  has 82%.  I always  said that if it was 20% it
could start to become interesting.  But once again, frankly, we are disappointed
but nevertheless we do everything to repair the situation.


MARK PERMA, ING FINANCIAL MARKETS

One follow up on Exubera(R).  You talked about early discussions on the value of
the project.  I wondered whether you could tell us if you believe that Pfizer is
overvaluing it or undervaluing it form your perspective?


JEAN-CLAUDE LEROY

I said that each company has designated a banker to valuate the products. We are
not yet discussing the value;  we are still in the process of valuing,  which is
one step behind.  So, I cannot answer your question with any more precision.  To
tell you the truth,  at the end of the day, I don't know what Pfizer's  position
will be. We'll know that later on.


Paris, 21 October 2004                                                        11



Conference Call                                                   sanofi-aventis


ING FINANCIAL MARKETS

I don't  understand  how you  can be in  disagreement  and  not  know  what  the
disagreement is about.


JEAN-CLAUDE LEROY

The  disagreement is something  different.  Pfizer decided that the operation we
made with  Aventis  triggered a change in  ownership  in the contract so that we
were in the  situation  where  they might  decide  whether to buy or they had us
buying the  product or status  quo.  We said that this event is not  triggering.
That's  the  reason  we're in  disagreement,  and not the next.  Each  party has
decided to have a banker designated. And at that time, that's where we are.


ING FINANCIAL MARKETS

So you have no idea  whether  they would like to get  Exubera(R)  full rights or
whether they would like to sell you the full rights?


JEAN-CLAUDE LEROY

No idea at all at that stage.


IXIS SECURITIES

Good afternoon. A couple of quick questions. First, a number of your competitors
are now  communicating,  will  communicate  next week, on their IFRS accounting.
Will we have some  presentation  on the impact of these new norms at the meeting
in March  2005 or will you  publish  your  accounts  according  to that?  Second
question,  on  Exubera(R),  on the papers filed by Aventis  during the take-over
period they mentioned there was a 45 day period for valuing the company, then 15
days for  deciding.  Would that apply here? Is there some sort of an action date
on that?  Lastly,  on the  growth of  Sanofi-Synthelabo,  it's up 17% in the Q3,
which is a bit down on the  first  half.  It  doesn't  seem to come from the top
products. Is that some weakness in old Sanofi tail products?


HANSPETER SPEK

[Inaudible.]  I said 17% against a market which is below 7%, and  compared  with
the previous  performance  which has been I think 18. I think it's really sad to
say it's an artefact. It's an artefact on top because we are so strongly driving
our base that 17% in the third quarter are probably  enough to come forth in 18%
in the first quarter.  So, now we say there is absolutely nothing and perhaps to
anticipate a question which may come up concerning  the year end sales,  we have
announced  nearly one year ago that we expect that our sales in 2004 would be on
the level of our sales in 2003.  And I can just  confirm you that more than ever
we are convinced this will come in exactly as predicted at the end of last year,
at the very beginning of this year. So, so far, on sales.


Paris, 21 October 2004                                                        12



Conference Call                                                   sanofi-aventis


FROM THE PANEL

On Exubera(R),  maybe to precise that the timing that was provided by Aventis at
the time once the clause is triggered. Here we are discussing about whether this
clause  has been  triggered  or not.  Once it is  triggered,  then you have some
timing to plan.  But we really not as far as that because we are  discussing  on
the  very  principles  of  the  triggering  of the  clause.  The  reason  why we
designated  a banker is that we wanted to protect  our rights and enter  about a
value  discussion  that  might not be at the end of the day  anything  more than
discussion  between  partners.  But it's still happening,  so both companies are
providing a valuation. But I would say we are outside of the scope of the clause
as of today  because  there is no agreement  that the clause has been  triggered
effectively.


JEAN-CLAUDE LEROY

Back to IFRS. I could say it's a bit early but obviously there is a beginning of
an answer that I can give. It is obvious for us that the opening valuation,  for
example,  we're going to have to do that from an IFRS perspective.  So in a way,
we will deliver - I'm sorry for that - several sets of figures. It's going to be
too many figures but in the meantime it may help to understand  the  performance
of the Group.  I just say that,  for  comparable  purpose  pro  formas,  we will
certainly try to deliver  under IFRS.  For the rest - the  consolidated  - if we
were to give the set of figures under French  rules,  we would have to give some
flavour of the reconciliation  with IFRS. So, one way or the other there will be
IFRS on here at the end of the year.


MERRILL LYNCH

Good afternoon, I've got four questions, please. The first is on Lovenox(R), and
the subpoena you've received.  If you could give us a little bit more feeling on
the  meaning  of that  subpoena  and what  the  next  steps  are.  Secondly,  on
Exubera(R), relating to the change of ownership clauses. As I understand it, the
manufacturing  plant of the  insulin  here is  actually  co-owned  by Pfizer and
sanofi-aventis.  I'm  wondering  if any clauses also apply to the plant or would
that remain partly in your hands  regardless  and therefore you would still,  in
the event that Pfizer acquired the product, keep the manufacturing supply there?
On Ketek(R), you talked about good forms of coverage in the United States. I was
wondering if you could just put a number to that.  Finally,  on the flu vaccine,
you talked  about 2.5 million for this year.  I was just  wondering  if upsizing
your production for next year's flu market might be an option.

HANSPETER SPEK

I start then with  Ketek(R).  We have about 70% of the  segment  here,  which we
really  find - keeping  in your  minds  once again that we are two months on the
market - is an excellent  result,  and [inaudible] has done a very good job. The
Exubera(R) plant, you are right. That's a plant. It's a specific dedicated plant
within the industrial park of Aventis in Frankfurt.  Our  interpretation  of the
situation is, if Exubera(R) would go to Pfizer, the plant would go with it.


Paris, 21 October 2004                                                        13



Conference Call                                                   sanofi-aventis


JEAN-CLAUDE LEROY

Regarding  Lovenox(R),  we received on 1 October a subpoena by the US Attorney's
Office in Chicago, that's right, concerning certain marketing practices relating
to Lovenox(R) from the beginning of 99 to [inaudible].  We are in the process of
responding  to the  subpoena,  providing  all the  information  which  has  been
required.


FROM THE PANEL

Regarding  the flu  vaccine  production  capacity,  we said last year during the
vaccine day that our  production  capacity has been  increased to 165 million of
dose on a world wide basis. You know that [inaudible] manufactures in Europe and
the US. We will produce next year according to this full capacity. This is being
discussed and this will depend obviously about our estimation for the demand for
the next year season.


REUTERS

A very basic  question.  I was just  wondering  if you could give us any sort of
guidance for the fourth quarter. I know you've said in the past that guidance is
unlikely  until  maybe  February.  But I was just  wondering  if there  were any
general comments as to how you think the fourth quarter might turn out?


JEAN-CLAUDE LEROY

Again, we've said, I'm sorry I'm going to repeat, that we're not going to give
any precise estimates on the fourth quarter nor on the year. Except, as I said,
unless there is a big problem the trends do not change that much from a quarter
to the other. I would just like to say that even though we said - and we're
going to do it - that we will deliver, provide next year figures and results on
a quarterly basis. Again, we're going to give the yearly guidance at the
beginning of the year but we don't intend to give guidance on a quarterly basis.


REUTERS

Would it be fair to say you're optimistic about the future despite all these
concerns over law suits and all the rest of it?


JEAN-CLAUDE LEROY

Yes, we are optimistic, definitely.


REUTERS
Just to  reiterate  then,  you don't  think the trends will change much from one
quarter to the next?


Paris, 21 October 2004                                                        14



Conference Call                                                   sanofi-aventis


JEAN-CLAUDE LEROY

You know that better than us in the pharmaceutical business.


HANSPETER SPEK

If I may add, I'm in charge from an operational  point of view. I think you will
agree that a certain part of what you see in terms of sales and what you hear in
terms of the integration  confirms that - I allow me to say - we relatively well
controlled and managed the situation.  So if you take that one fact and you take
on the other side what has been announced previously by both companies,  I think
it is fair to say that  there is no  indication  to expect,  on the  operational
level, any bad surprises until the end of the year.


MICHAEL ECHOP, COMMERZBANK

Just two brief questions.  I just wanted to check to make sure that I understand
the basis of the pro forma net sales you've presented.  I understand that you've
excluded  Arixtra(R) and Fraxiparine(R)  from the end of August 2004. What about
the other divestments  mandated by the anti-trust  issues? I know in the F-4 you
recently  filed  the pro  formas  included  those  products.  I just want to see
whether the pro formas you  presented  today  include or exclude the EU mandated
disposals. Second, Exubera(R): I understand there's this debate going on between
yourselves  and  Pfizer  about  control.  What would be your  preference  for an
outcome there?


JEAN-CLAUDE LEROY

I will begin by the most difficult one, which is the pro formas.  I guess that I
have to give some explanation.  I said that in the consolidated  figures,  which
are  only  represented  in  the  ex-Sanofi-Synthelabo  figures,  Arixtra(R)  and
Fraxiparine(R)  are consolidated up to the divestment,  which are cut at the end
of  August.  As far  as  the  pro  formas,  this  is  exactly  to the  contrary.
Arixtra(R),  Fraxiparine(R),  as well as Campto(R)  from the Aventis side,  have
been excluded from the whole sequences which have presented. They have been sold
at the  beginning of 2003,  so that they do not appear in 2003 or 2004,  so they
don't belong to the comparison. As for the rest of the products, which we are in
the process of divesting,  because of the demand of Brussels,  their  divestment
has not yet occurred. I mean by that, that we have not yet signed agreements. We
are on the verge of signing  agreements  but we have not signed  agreements.  As
soon as we have signed agreements for disposing of these products, we will treat
them exactly the same way we've treated Arixtra(R), Fraxiparine(R) and Campto(R)
for they will  disappear from the sequence.  Now just  reminding  everybody that
we've all in all - apart  from the three main  products - we're only  talking of
products which total roughly (euro)50 million of yearly sales. So it's not going
to make any difference even on a reported basis, in any case, as compared to the
(euro)25 billion of pro forma sales.


HANSPETER SPEK

I  disagree  with  Jean-Claude  that he has the  difficult  question.  The other
question you raised about what our company would like is, for many reasons, much
more  difficult  to  answer.  Nevertheless,  I want  to  try.  From a  marketing
standpoint, I have just a couple of weeks looking to this product, so


Paris, 21 October 2004                                                        15



Conference Call                                                   sanofi-aventis


this has reservations. It is quite fascinating to imagine that we could offer to
a patient being obliged to have an injection or several  injections  every day a
totally different way of  administration,  which most likely is more convenient.
That is for the  charming  side of the  product.  If you go more  into  details,
especially  into the  economics,  it is clear  that the  market  access for this
product - especially to the European  markets here - is much more  questionable.
Because I am , frankly,  totally  incapable of answering that question today: to
which extent the  European  health care systems are ready to pay for a different
application form a more or less  significantly  higher price. To answer, we need
much  more data and much more  discussions  also with  Pfizer in order to really
evaluate the potential of this product, especially outside the US. So, in short,
as always,  there are  positives,  there are less  positives,  and we are at the
beginning to evaluate and will need to discuss this further with Pfizer.


DEUTSCHE BANK

Four quick questions. Quickly on Exubera(R), whether you can give us any idea on
the  timing  of the  court  decision  as to  whether  change  control  has  been
exercised.  Secondly,  since we have you  Jean-Claude,  whether you can make any
comment on what level of options are now  outstanding as regards the old Aventis
business.  The  potential  options  charge from  counting the stock  options was
pretty high in the Aventis  business,  and I'm  wondering if you can give us any
feel  as to  where  that  might  be at the  present  time.  You  mentioned  that
Eloxatine(R)  has been on the market for eight years in France.  I just wondered
whether  you could  give us an idea how long  it's  been on the  market in other
major European  territories so we can have some idea when its exclusivity around
Europe  comes to an end?  Finally,  historically  Aventis did have a tendency to
sell some of its tail products, and it booked significant profits as a result. I
wonder if you'd  give us any idea  whether  you can  comment  at all on that old
policy in your view, and as a consequence  whether we should assume such profits
will no longer continue? Thank you.


HANSPETER SPEK

Eloxatine(R)  is  relatively  an easy one. The French market has more or less an
exclusivity  within Europe for two or three years and then we started  launching
in the other major markets. But then it took another, I would say, three or four
years to launch in the latest  market,  which have been then the United  Kingdom
and  Italy  was one also of the later  markets.  So to sum it up, in the  latest
European markets, the product is only available since approximately three years.


JEAN-CLAUDE LEROY

Too early to answer your question on the stock options. We will comply with IFRS
policy  when it comes to book that.  So more  information  to come on the impact
when we deliver the yearly set of accounts.


DEUTSCHE BANK

Can I ask  whether  most of the  options  were  rolled  over  that  the  Aventis
personnel had previously?


Paris, 21 October 2004                                                        16



Conference Call                                                   sanofi-aventis


JEAN-CLAUDE LEROY

Yes,  definitely.  The merger we launched  will  exactly  keep the rights of the
stock  option  holders  with a  consideration  which is  exactly in the ratio of
exchange.  So,  no  change  at  all.  As  far  as the  tail  products  portfolio
divestiture  policy.  I guess  we've been clear since the launch of the offer on
Aventis,  and we've not changed our minds in that. We do not consider that it is
a way to have a bottom line by selling  products just to match  through  capital
gain what is the  expectation of the market.  Now, I'm not saying at all, that a
tail product,  a small product,  that to be divested  because they would be much
better in other  areas.  We will not do it. We are just  saying that it is not a
policy of  sanofi-aventis to sell the portfolio and to make the bottom line. So,
no change in the policy  since 26 January,  and that's what we're going to do in
the future.


DEUTSCHE BANK

OK, so it would be fair to regard  profits made on those products as exceptional
historically?


JEAN-CLAUDE LEROY

Exactly.  Now, on Exubera(R),  we've said about everything that we're capable of
saying today.  Again, we've told you a lot which in turn got to nothing at news.
Compared to the situation  three months ago,  we'll give more news to the market
when we can but  it's too  early to say  more.  We don't  know  more at the time
being.

DEUTSCHE BANK

The hearing has been heard,  and a verdict is waiting to be delivered.  Any idea
when that verdict may be delivered from the court?


JEAN-CLAUDE LEROY

Not at all; no idea at all.


JEROME BERTON, NATEXIS

Most of my  questions  have  been  answered.  I wanted  to know,  regarding  the
decision  from  BMS to cut part of its  sales  force to  promote  Avapro(R)  and
Provaco,  I was  wondering  whether  you had some  plans  to fill  the  gap,  to
reallocate  part of your sales force or  renegotiate  the  agreement  with them.
Secondly, could you just confirm that, apparently the integration is going quite
well and is on  track,  would you  confirm  that you  still  expect  some 10% of
synergies in 2004?


HANSPETER SPEK

On BMS, yes, we don't have any plans but we are having active conversations with
Bristol Myers Squibb.  There is no underlying agreement that both products still
have  enormous  potential in the US and outside.  There is a total  agreement on
both sides that the investment in both products

Paris, 21 October 2004                                                        17



Conference Call                                                   sanofi-aventis


should not be, may not be,  reduced in the country.  Consequently,  we are today
actively  evaluating,  together with Bristol Myers Squibb,  how to cope with the
new situation which highlighted as you said Bristol Myers Squibb's  reduction of
headcount in the US. On the other side,  Sanofi has through  sanofi-aventis  new
and more  opportunities  than before.  So far, those  conversations  go the same
constructive  way as they went in the previous  past when we had similar  issues
between the two partners.  Consequently, we are confident that by the end of the
year, we will have adequate  decisions in place,  from the promotional angle but
of course also from the subsequent  financial and economic angles, which have to
take into account what each side is able and ready to contribute.


NATEXIS

If I understand  well,  the  investment  from both parties  could not be reduced
according to the agreement but you're in  discussions on the  consideration.  Is
that right?


HANSPETER SPEK

I did not mention the agreement. I said there is a common understanding that the
investment should not be decreased because it would be a mistake in front of the
opportunity.  So there is a total agreement that the investment in both products
should not only be  maintained  but should  also be  accelerated.  This could be
matched with the given  situation  as you quoted it  correctly of Bristol  Myers
Squibb.  So we have  just to sit  together  and  find  ways how we  realise  the
necessary  investment and how we split  consequently the subsequent  incremental
results.


JEAN-CLAUDE LEROY

As to the synergies, you were asking the question, will we deliver? I could also
answer  for  Hanspeter  and for Gerard Le Fur,  and for the rest of the  central
function.  We are  definitely  taking  some  decisions,  some of which  are also
official,  I  mean  outside,  information  of  where  we're  going  to  put  the
headquarters in several  important  countries.  We are also, as you may imagine,
reviewing  the  portfolio  and  trying  to do  things  in the R&D  area.  We are
definitely  doing things in the outside experts and operations  area. So, yes, I
can confirm  that we are in the process of  delivering  the kind of synergies we
have been addressing the market with.


HANSPETER SPEK

Just to add to this,  we have already  today in most  European  markets,  former
Aventis  sales people  promoting  Aprovel(R)  and  Plavix(R),  and former Sanofi
people promoting  former Aventis products such as Ketek(R),  and we have exactly
the same  agreements  already in place,  which means that the people are already
actively  visiting  the  doctors  in the  US.  So we  have  fixed  a  number  of
[inaudible] which gives already in 2004 some additional incremental sales. I can
confirm what  Jean-Claude  said, I come out of our first  meeting with  regional
people on the future  structure,  and coming from some of those meetings,  I can
confirm that in terms of structure we will fully deliver what we have  announced
since the mid of the year.


Paris, 21 October 2004                                                        18



Conference Call                                                   sanofi-aventis


NATEXIS

Just a follow up question. Just to come back again on Exubera(R),  you said that
you don't have any precise idea about the timing of the decision coming from the
judge.  It could take some weeks,  some months.  Could we have a final answer by
the end of this year? What is you assumption?


HANSPETER SPEK

Frankly,  we have none. I can add that it is not one judge; it is several judges
because  there is a litigation in Europe and another one in the US. So, there is
no more precise answer possible.


SANJAY GUPTA

We are  coming  to the end of the time  period.  Can we take  one last  question
please?  You will have the opportunity to approach Investor  Relations and we'll
be happy to answer your questions in the days and weeks ahead.


NIKEI

You have mentioned during your  presentation when you explained about Allegra(R)
you talked  about  something  not going very good in Japan.  What's the  problem
there with Allegra(R)?  Also, in Japan, as you know, there were big operation by
Aventis,  and  small  operation  by  Sanofi.  How did you  straighten  that  up?
Everything is now organised and  straightened  up so that everyone  works in the
corporate way?


HANSPETER SPEK

To answer the Allegra(R)  question,  we really have to go into biology. I had to
learn that there's a strong two year seasonality for  antihistamine  products in
Japan because  every second year,  there's a special tree which is widely spread
over Japan - it's a cedar kind of tree -  produces  pollen.  This has a dramatic
impact on rhinitis. The next year will be 2005, and has not been 2004. So if you
analyse,  you see that Allegra(R) in fact even was gaining market share within a
shrinking  market  in 2004.  But for this  given  situation  we are  very,  very
confident for 2005 to come back with two digit growth.


NIKEI

So it's a natural  phenomenon:  it just goes up and down,  and  that's the worst
turn and then it will improve?


HANSPETER SPEK

Yes,  absolutely.  There is another  underlying effect which is independent from
this  biological  pollen  situation,  which is the very, very positive trend the
product has in dermatology in Japan.


Paris, 21 October 2004                                                        19



Conference Call                                                   sanofi-aventis


NIKEI

And for the organisational issues?


HANSPETER SPEK

The  organisational  issues are,  frankly,  minor issues in Japan. You know that
Sanofi has a very small unit of slightly  more than 100 people,  which is mainly
managing the existing  agreement,  and the rest is clinical  development.  Those
people  are  already  in the  process  of  being  actively  integrated  into the
structure of Aventis Japan. They are in the process of moving out of the current
building.  So,  we don't  see  there  major  synergies  but of  course  the real
synergies are to come. You may know that we are in a very final stage of getting
chlopidogrel  approved in Japan. It will not be marketed as a license. We have a
joint venture agreement in which sanofi-aventis will play an important role. And
of course we have significant expectations in this respect.


SANJAY GUPTA

I think  that  that's  about  it.  Thank  you very  much for  your  interest  in
sanofi-aventis. Thank you.
