On October 24, 2003, we published our results for the six months ended June 30,
2002, prepared in accordance with French GAAP in the Bulletin des Annonces
Legales Obligatoire (the BALO) as required by French law.

Included in this current report on Form 6-K is an English language translation
of the half-year management report (rapport semestriel) and our unaudited
interim financial statements for the six months ended June 30, 2003, prepared in
accordance with French GAAP. We originally included this information in our
current report on Form 6-K, dated October 27, 2003. The only differences between
the information included in this current report on Form 6-K and the information
included in the publication in the BALO and in our current report on Form 6-K,
dated October 27, 2003 relate to the deletion of the non-GAAP measure
Consolidated net income before exceptional items and goodwill amortization, and
the related EPS, and discussion of those measures from the management report
and in the interim consolidated financial statements.

As in our current report on Form 6-K, dated October 27, 2003, we have omitted
the certification of our auditors, included in the BALO publication, as well as
certain information regarding our insurance coverage required by the rules of
the Commission des operations de bourse that we do not consider material to
investors.

                                MANAGEMENT REPORT
                    ON THE CONSOLIDATED FINANCIAL STATEMENTS
                              OF SANOFI-SYNTHELABO
                     FOR THE SIX MONTHS ENDED JUNE 30, 2003

Highlights of the first half of 2003 were:

-     growth in consolidated net sales ahead of pharmaceuticals market growth;

-     confirmation of the success of Eloxatin(R) in the treatment of colorectal
      cancer, both in Europe and in the United States, where Eloxatin(R) was
      launched in September 2002;

-     dynamic performances from other strategic products such as Plavix(R),
      Aprovel(R), and Ambien(R)/Stilnox(R),

-     earnings growth amongst the best achieved by any of the pharmaceuticals
      majors;

-     continuation of the share buy-back programs initiated in May 2002.


During the first half of 2003, Sanofi-Synthelabo recorded CONSOLIDATED NET SALES
of 3,903 million euros, AN INCREASE OF 14.4% ON A COMPARABLE BASIS and 6.1% on a
reported basis.

OPERATING PROFIT for the six months to June 30, 2003 came to 1,391 million
euros, a rise of 12.8%. The operating margin rate was 35.6%, compared with 33.5%
in the first half of 2002. This advance was achieved in spite of negative
movements in the exchange rates of the main currencies against the euro. AT 2002
EXCHANGE RATES, OPERATING PROFIT WOULD HAVE SHOWN AN INCREASE OF 30.3% RELATIVE
TO THE FIRST HALF OF 2002.

CONSOLIDATED NET INCOME for the six months to June 30, 2003 was 944 million
euros, against 830 million euros for the six months to June 30, 2002, a rise of
13.7%. This represented 24.2% of consolidated net sales, against 22.5% for the
six months to June 30, 2002. At 2002 exchange rates, the increase would have
been 27.4%. EARNINGS PER SHARE came to 1.34 euros, compared with 1.13 euros in
the first half of 2002, A RISE OF 18.6%.

SALES

DEVELOPED SALES

When we refer to "developed sales" of a product, we mean consolidated sales,
excluding sales of products to our alliance partners, but including those that
are made through our alliances and which are not included in our consolidated
sales. These alliances are with Bristol-Myers Squibb on Plavix(R)/Iscover(R)
(clopidogrel) and Aprovel(R)/Avapro(R)/Karvea(R) (irbesartan), with Fujisawa on
Stilnox (R)/Myslee(R) (zolpidem), and with Organon on Arixtra(R) (fondaparinux).
Our alliance partners provide us with information regarding their sales in order
to allow us to calculate developed sales.

We believe that developed sales are a useful measurement tool because they
demonstrate trends in the overall presence of our products in the market.

The table below reconciles consolidated net sales to developed sales.

                                       4

IN THE UNITED STATES:

-     Invoiced sales of Plavix(R) in the first quarter of 2003 fell by 14% on a
      comparable basis, largely due to a sharp reduction in shipments to
      wholesalers in response to a change in the marketing policy adopted by
      Bristol-Myers Squibb.

-     Second-quarter invoiced sales of Plavix(R) saw robust growth of 50.5% on a
      comparable basis. This growth corresponds to invoiced sales in line with
      demand, and also reflects a favorable comparative base, as Bristol-Myers
      Squibb only began its inventory workdown in the second quarter of 2002.

-     Over the first half of 2003, demand for Plavix(R) continued to grow at a
      sustained pace, with prescriptions up 26.7% (Prescription IMS YTD June
      2003 retail + mail order + long term care), coupled with a favorable price
      effect.

-     Given the very strong growth in prescriptions and the current level of
      inventories held by American wholesalers, full-year invoiced sales should
      be close to demand.

OUTSIDE THE UNITED STATES, first-half sales rose by 33.5% on a comparable basis.

DEVELOPED SALES OF APROVEL(R)/AVAPRO(R)/KARVEA(R) CAME TO 591 MILLION EUROS IN
THE FIRST HALF OF 2003, AN INCREASE OF 18.4% ON A COMPARABLE BASIS.

-     IN THE UNITED STATES, second-quarter sales of Avapro(R) reached 90 million
      euros. Over the first half, prescriptions grew by 14.0% (Prescriptions IMS
      YTD June 2003 retail + mail order + long term care), coupled with a
      favorable price effect. Invoiced sales were in line with demand over the
      first half. The lack of comparable-basis growth was due to an unfavorable
      comparative base, the inventory workdown being implemented by
      Bristol-Myers Squibb from the second half of 2002.

-     OUTSIDE THE UNITED STATES, first-half sales rose by 29.2% on a comparable
      basis.

CONSOLIDATED FINANCIAL STATEMENTS

The consolidated financial statements of Sanofi~Synthelabo and its subsidiaries
(the "Group") have been prepared in accordance with Rule 99-02 of the Comite de
la Reglementation Comptable ("CRC") issued April 29, 1999 and applicable with
effect from January 1, 2000, and with Recommendation 99 R 01 of the CRC issued
March 18, 1999 on interim financial statements.

The accounting policies and methods used are identical to those applied in the
preparation of the financial statements for the year ended December 31, 2002,
except for the adoption with effect from January 1, 2003 of CRC Rule 2002-10 on
the depreciation and impairment of assets, which had no material impact on the
first-half consolidated financial statements.


CONSOLIDATED STATEMENT OF INCOME

CONSOLIDATED NET SALES

Consolidated net sales reached 3,903 million euros in the first half of 2003, an
increase of 14.4% on a comparable basis and 6.1% on a reported basis.

When we refer to the change in our sales on a "comparable" basis, we mean that
we exclude the impact of exchange rate fluctuations and changes in Group
structure (acquisitions and divestitures of entities and rights to products as
well as change in the consolidation percentage for consolidated entities).

For any two periods, we exclude the impact of exchange rates by recalculating
sales for the earlier period on the basis of exchange rates used in the later
period.

We exclude the impact of acquisitions by including sales for a portion of the
prior period equal to the portion of the current period during which we owned
the entity or product rights based on sales information we receive from the
party from whom we make the acquisition. Similarly, we exclude sales in the
relevant portion of the prior period when we have sold an entity or rights to a
product.

For a change in the consolidation percentage of a consolidated entity, the prior
period is recalculated on the basis of the consolidation method used for the
current period.

Currency fluctuations had an unfavorable impact of 7.8 percentage points over
the half-year. Of this, half was due to the weakening of the US dollar (in the
first half of 2003, the euro on average appreciated by more than 20% against the
dollar relative to the first half of 2002), and the rest was due to the weakness
of certain Latin American and Asian currencies. Changes in Group structure had
an unfavorable impact of 0.5 of a percentage point during the year to June 30,
2003, due primarily to the change from full consolidation to 51% proportionate
consolidation of Sanofi-Synthelabo Fujisawa (Taiwan) in May 2002.

-     IN EUROPE, FIRST-HALF CONSOLIDATED NET SALES REACHED 2,320 MILLION EUROS,
      7.9% higher on a comparable basis. Excluding sales of finished products to
      Bristol-Myers Squibb, comparable-basis growth was 8.2% in the first half,
      a higher growth rate than that of the market (7.3% IMS YTD retail to end
      May).

-     IN THE UNITED STATES, FIRST-HALF CONSOLIDATED NET SALES REACHED 884
      MILLION EUROS, an increase of 40.1% on a comparable basis and 16.9% on a
      reported basis, the difference being entirely due to fluctuations in the
      dollar/euro exchange rate. This performance was due to the success of
      Eloxatin(R), which generated sales of 213 million euros, and to the
      progress made by Ambien(R), which posted 516 million euros in sales, an
      increase of 24.0% on a comparable basis.

-     IN THE REST OF THE WORLD, sustained growth in Asia and a recovery in Latin
      American operations led to FIRST-HALF SALES OF 699 MILLION EUROS, up 11.0%
      on a comparable basis but down 6.7% on a reported basis. The fall in the
      reported-basis figure was due to the weakness of some Latin American and
      Asian currencies during the first half, and to the change to 51%
      proportionate consolidation of Sanofi-Synthelabo-Fujisawa (Taiwan).


CONSOLIDATED NET SALES BY PRODUCT (comparable-basis figures)


FIRST-HALF CONSOLIDATED NET SALES OF THE GROUP'S TOP 10 PRODUCTS WERE 2,574
MILLION EUROS, AN INCREASE OF 30.4% (21.1% on a reported basis).

THESE TOP 10 PRODUCTS REPRESENTED 65.9% OF FIRST-HALF CONSOLIDATED NET SALES,
compared with 57.9% in the first half of 2002.

During the first half of 2003:

-     CONSOLIDATED NET SALES OF STILNOX(R)/AMBIEN(R)/MYSLEE(R) WERE 627 MILLION
      EUROS, a rise of 20.8%. In the United States, the product recorded sales
      of 516 million euros, up 24.0%. In Japan, consolidated net sales of
      Myslee(R) were 23 million euros, up 23.7%.

-     CONSOLIDATED NET SALES OF PLAVIX(R) TOTALED 612 MILLION EUROS, a rise of
      27.0%. Excluding sales of active ingredient and finished products to
      Bristol-Myers Squibb, Plavix(R) posted sales growth of 38.3%.

-     CONSOLIDATED NET SALES OF ELOXATIN(R) TOTALED 384 MILLION EUROS, an
      increase of 220.0%. This very strong growth reflects the continuing
      success of Eloxatin(R) in the United States, where it achieved sales of
      213 million euros. Outside the United States, sales advanced by 43.4%.

-     CONSOLIDATED NET SALES OF APROVEL(R) WERE 334 MILLION EUROS, up 29.5%,
      underlining the success of this product, especially in Europe.

-     Consolidated net sales of Arixtra(R) remained low at 8 million euros, due
      to the current narrow range of indications. The program aimed at extending
      indications for Arixtra(R) is on track.


Apart from the top 10 products, the rest of the portfolio generated sales of
1,329 million euros in the first half of 2003, a decline of 7.6%. Stripping out
the fall in sales of Ticlid(R) and the virtual disappearance of sales of
Corotrope(R)/Primacor(R) (since the introduction of generics in the United
States in May 2002), sales of the other products in the portfolio were almost
unchanged (-0.4%).


                                       8

GROSS PROFIT

Gross profit was 3,153 million euros, an increase of 6.0%. At 2002 exchange
rates, growth in gross profit would have been 16.9%.

The GROSS MARGIN RATE was unchanged relative to the first half of 2002 at 80.8%,
reflecting:

-     Negative currency effects, in particular on royalties paid by
      Bristol-Myers Squibb on invoiced sales of Plavix(R) and Avapro(R) in the
      United States. At 2002 exchange rates, the gross margin rate would have
      been 81.9%, an improvement of 1.1 percentage points.

-     A further improvement in the product mix, due to sustained growth for the
      major products and in spite of the very strong rate of growth in sales of
      Eloxatin(R), on which gross margin is lower than the Group figure due to
      royalties paid to our alliance partner Debiopharm.


RESEARCH AND DEVELOPMENT EXPENSES

Research and development expenses increased by 5.8% to 621 million euros and
represented 15.9% of consolidated net sales, the same proportion as in the first
half of 2002. At 2002 exchange rates, research and development expenses would
have risen by 12.9%. This increase was mainly due to major clinical trials
programs covering products already on the market (Plavix(R),
Aprovel(R)/Avapro(R)) and new molecules in phase III of development (Rimonabant,
Zolpidem MR, Idraparinux).

In 2003, our continuing efforts in research and development were rewarded by:

-     Announcement in June 2003 at the 39th annual conference of the ASCO
      (American Society of Clinical Oncology) of major results with Oxaliplatine
      (Eloxatin(R)), clearly demonstrating consistent superiority in the
      treatment of colorectal cancer in all settings of the disease (early
      stage, adjuvant treatment after surgery, metastatic settings).

-     Approval in June 2003 by the US Food and Drug Administration of
      Uroxatral(R) in the treatment of the signs and symptoms of benign
      prostatic hypertrophy.

-     Approval in June 2003 by the US Food and Drug Administration, and
      favorable opinion in July 2003 from the Committee for Proprietary
      Medicinal Products on approval for marketing in Europe, for Arixtra(R) in
      the long-term prevention of deep venous thrombosis in patients undergoing
      hip fracture surgery.

-     Announcement in July 2003 at the 19th conference of the ISTH
      (International Society on Thrombosis and Haemostasis) of favorable results
      with Arixtra(R), demonstrating a significant reduction of the risk of deep
      venous thrombosis in medical patients (ARTEMIS study) and benefits in
      prevention of deep venous thrombosis after major abdominal surgery
      (PEGASUS study).

SELLING AND GENERAL EXPENSES

Selling and general expenses amounted to 1,204 million euros, 2.8% lower than in
the first half of 2002. At 2002 exchange rates, they would have risen by 5.1%,
with marketing spend up by 6.6% and general expenses stable.

The increase in marketing resources and the sales force was concentrated in the
United States to support the growth of Ambien(R) and the launch of Eloxatin(R),
and to prepare for the launch of Uroxatral(R).

In Europe, sales and marketing efforts were maintained in order to provide
further support for sales growth.

In Latin America, local structures were adapted to take account of the economic
crisis, especially in Argentina and Brazil.

OTHER OPERATING INCOME AND EXPENSES

Other operating income and expenses relate primarily to transfers to and from
our partners in respect of profit sharing arrangements under joint venture and
alliance agreements on product marketing and development. The effects of these
profit sharing arrangements are reflected in operating profit.

During the first half of 2003, other operating income and expenses, relating
primarily to joint operations with Bristol-Myers Squibb, represented a net gain
of 63 million euros, against 85 million euros for the first half of 2002. At
2002 exchange rates, this item would have shown an increase of 12.9%.

The year-on-year change reflects the following factors:

      -     Negative currency effect on the share of profits generated by
            Plavix(R) and Avapro(R) in the United States transferred by
            Bristol-Myers Squibb.

      -     A marked increase in profits transferred to Bristol-Myers Squibb as
            a result of the strong growth of Plavix(R) and Aprovel(R) in Europe.

In the first half of 2003, our share of the profits generated by Plavix(R) and
Avapro(R) in North America, the territory managed by Bristol-Myers Squibb, came
to 153 million euros, against 171 million euros in the first half of 2002.
Conversely, the profits transferred to Bristol-Myers Squibb in respect of the
territory managed by Sanofi~Synthelabo amounted to 83 million euros in the first
half of 2003, compared with 66 million euros to end June 2002.

OPERATING PROFIT

Operating profit for the first half of 2003 came to 1,391 million euros, 12.8%
higher than in the first half of 2002. At 2002 exchange rates, growth in
operating profit would have been 30.3%. In spite of unfavorable currency
effects, the operating margin rate advanced by more than 2 percentage points to
35.6%, against 33.5% for the first half of 2002.

In geographical terms, operating profit made progress in all regions. However,
the 20% fall in the US dollar against the euro held back growth in profits
generated in the United States.

Europe accounted for 45% of consolidated operating profit before unallocated
costs, against 44% in the first half of 2002.

The United States contributed 42% of consolidated operating profit before
unallocated costs, against 43% in the first half of 2002.

Unallocated costs consist mainly of fundamental research and worldwide
development of pharmaceutical molecules, and part of the cost of support
functions.

INTANGIBLES - AMORTIZATION AND IMPAIRMENT

Amortization and impairment of intangibles increased from 55 million euros in
the first half of 2002 to 66 million euros in the first half of 2003, due to a
full six months of amortization charges for the rights to Ambien(R) in the
United States, acquired in April 2002.

NET FINANCIAL INCOME

During the first half of 2003, net financial income totaled 63 million euros,
compared with 28 million euros in the first half of 2002. Despite a reduction in
the Group's net cash position as a result of the share buy-back program
initiated in 2002 and a fall in the rate of interest on the investment of
surplus cash, net financial income showed an overall improvement due to the
following factors:

      -     A net foreign exchange gain of 53 million euros in the first half of
            2003, compared with 13 million euros in the first half of 2002.

      -     A charge of 20 million euros in the first half of 2003 to the
            provision for treasury shares allocated to stock option plans,
            compared with the 38 million euro charge taken in the first half of
            2002.


                                       11

INCOME BEFORE TAX AND EXCEPTIONAL ITEMS

Income before tax and exceptional items totaled 1,388 million euros, 15.1%
higher than in the first half of 2002.

INCOME TAXES

Income taxes amounted to 458 million euros, against 313 million euros in the
first half of 2002. The Group's effective tax rate was abnormally low in the
first half of 2002 at 25.8%, due to the write-back of provisions for taxes of
some 50 million euros and to the non-taxation of the share of the Lorex joint
venture profits transferred to Pharmacia in April 2002. The effective tax rate
for the first half of 2003 was 33%, close to the level recorded in the second
half of 2002 (32%).

INCOME FROM EQUITY INVESTEES

The share of net income from equity investees for the first half of 2003 was 19
million euros, mainly comprising the share of 2002 profits to which
Sanofi-Synthelabo is entitled via its interest in the Yves Rocher group. The
treatment applied to this item is unchanged from the first half of 2002, when
the amount involved was very similar.

MINORITY INTERESTS

Minority interests came to 2 million euros, against 83 million euros in the
first half of 2002. The 2002 first-half figure mainly comprised the entitlement
of Pharmacia to a share in the profits of the Lorex joint venture for the period
from January 1, 2002 through April 16, 2002.

NET INCOME AND EARNINGS PER SHARE

CONSOLIDATED NET INCOME came to 944 million euros, up 13.7% on the first half of
2002.

EARNINGS PER SHARE CAME TO 1.34 EUROS, AGAINST 1.13 EUROS FOR THE FIRST HALF OF
2002, A RISE OF 18.6%. EXCLUDING CURRENCY EFFECTS, THE INCREASE WOULD HAVE BEEN
31.9%.
The difference between growth in net income and growth in earnings per share was
mainly due to the impact of the share buy-back program initiated in 2002. The
average number of shares used to calculate earnings per share for the first half
of 2003 was 706.5 million, against 731.8 million for the first half of 2002.


                                       12

CONSOLIDATED STATEMENT OF CASH FLOWS

Operating cash flow before changes in working capital for the first half of 2003
was 1,114 million euros, 2.5% higher than the 2002 first-half figure of 1,087
million euros. This modest rate of growth was due mainly to the inclusion in the
first half of 2002 of minority interest payments to Pharmacia in operating cash
flow before changes in working capital.

Working capital needs rose by 355 million euros during the period, compared with
an increase of 697 million euros in the six months to June 30, 2002. The rise
during the first half of 2003 was mainly due to an increase in accounts
receivable and to payments made in respect of tax reassessments accepted in
2002.

Total investments amounted to 185 million euros, compared with 1,014 million
euros in the six months to June 30, 2002. Acquisitions during the first half of
2002 included the buyout of 51% of the Lorex joint venture in the United States.

Proceeds from disposals of fixed assets, net of income taxes, came to 5 million
euros, against 14 million euros in the first half of 2002.

Dividends paid to Sanofi-Synthelabo shareholders represented 579 million euros,
compared with 473 million euros in 2002, an increase of 22.4%. The dividend per
share rose by 27.2%, from 0.66 of a euro to 0.84 of a euro per share. Treasury
shares are not entitled to dividends, limiting the overall amount of dividend
paid.

The movement in other financing activities corresponds to the implementation of
the share buy-back programs authorized by the General Meetings of May 22, 2002
and May 19, 2003, which resulted in the purchase during the period of 13,940,301
shares for a total amount of 688 million euros. These shares are netted off
consolidated shareholders' equity. Disposals of shares in connection with stock
option plans amounted to a total of 4 million euros.

After all these cash flows, the amount of cash and cash equivalents (defined as
liquid assets, excluding treasury shares classified as short-term investments)
shown in the statement of cash flows fell by 790 million euros during the first
half of 2003.

CONSOLIDATED BALANCE SHEET

The balance sheet total was 8,837 million euros as of June 30, 2003, 622 million
euros lower than as of December 31, 2002.

Shareholders' equity was 5,591 million euros, a drop of 444 million euros.
Shares purchased under the share buy-back program and netted off shareholders'
equity totaled 1,651 million euros, including 688 million euros acquired during
the first half of 2003.

The main balance sheet items showing material movements relative to December 31,
2002 were:


                                       13

ASSETS:

      -     Accounts receivable rose by 238 million euros, in line with the
            expansion of the Group's sales, especially in the United States.

LIABILITIES:

      -     Other current liabilities fell by 90 million euros, mainly as a
            result of the payment during the period of tax reassessments
            accepted in 2002.

      -     Short-term debt fell by 103 million euros, largely due to the
            repayment of loan installments.


The Group had a net positive net cash position of 1,967 million euros at the end
of the period, against 2,672 million euros as of December 31, 2002, after taking
account of 599 million euros of treasury shares held in connection with stock
option plans as of June 30, 2003.

RECENT EVENTS

-     As of August 31, 2003, the Group held 32.3 million shares acquired under
      the share buy-back programs authorized by the General Meetings of May 22,
      2002 and May 19, 2003, representing 4.41% of the share capital and
      amounting to 1,749 million euros. These figures do not include treasury
      shares held in connection with stock option plans.

-     In connection with the Plavix litigation in the United States, and as
      announced on June 20, 2003, patent "328" expiring 2014 has been withdrawn
      from the patent infringement action and will be delisted from the Food and
      Drug Administration "Orange Book". This withdrawal has no effect on
      product patent "265" expiring 2011, which protects clopidogrel, the active
      ingredient of Plavix, which we are confidently defending. As regards the
      action itself, fact discovery is scheduled to end on October 15, 2003,
      with the pre-trial order expected towards mid-2004. The trial itself will
      follow, on a date to be fixed by the Court.

OUTLOOK FOR 2003

The acceleration in sales growth during the first half has enabled us to upgrade
our forecast for 2003 full-year sales growth, which we now expect to be in the
region of 15% on a comparable basis, as opposed to our initial forecast of
12.8%.

At the same time, the second half of 2003 will see an acceleration in spending
on research and development associated with ongoing clinical trials, plus a
reinforcement of marketing resources, especially in the United States ahead of
the launch of Uroxatral.


                                       14

Even after this investment in our future, we anticipate 2003 full-year growth in
earnings per share before exceptional items and goodwill amortization of close
to 20% at an average annual rate of 1.10 dollars to the euro (as opposed to the
1 dollar per euro rate previously used). This equates to a 20% upward revision
to the previously-announced forecast rate of growth in 2003 full-year earnings
per share before exceptional items and goodwill amortization. The sensitivity of
this growth rate to fluctuations in the dollar is unchanged, at 1% for a 3-cent
movement.

SANOFI-SYNTHELABO PARENT COMPANY

The statement of income of the Sanofi-Synthelabo parent company for the six
months ended June 30, 2003 shows income before tax and exceptional items of 883
million euros, compared with 771 million euros for the six months ended June 30,
2002.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                         SIX MONTHS ENDED JUNE 30, 2003


A.    BASIS OF PREPARATION

      The consolidated financial statements of Sanofi-Synthelabo and its
      subsidiaries (the << Group >>) have been prepared in accordance with Rule
      99-02 of the Comite de la Reglementation Comptable ("CRC") issued April
      29, 1999 and effective as of January 1, 2000, and CNC recommendation 99 R
      01 of March 18, 1999 on interim accounts.

      The accounting policies and methods used are identical to those applied in
      the preparation of the financial statements for the year ended December
      31, 2002, except for the adoption as of January 1, 2003 of the rule CRC
      2002.10 concerning the amortization and impairment of assets. This has no
      significant impact on the consolidated financial statements for the six
      months period ended June 30, 2003.

      Pursuant to the new CRC Rule 2000-06, which became effective as of January
      1, 2002, the Group reviewed all its liabilities as of that date for
      compliance with the new rule. The impact of applying this new rule was an
      adjustment to shareholders' equity of 24 million euros net of income
      taxes.

      The consolidated financial statements for the 6 months ended June 30, 2003
      should be read in conjunction with the consolidated financial statements
      for the year ended December 31, 2002.


B.    ALLIANCE AGREEMENTS WITH BRISTOL-MYERS SQUIBB (BMS)

      Two of the Group's leading products were jointly developed with BMS : the
      anti-hypertensive agent irbesartan (Aprovel(R) / Avapro(R) / Karvea(R)
      and the atherothrombosis treatment clopidogrel (Plavix(R) / Iscover(R).

      Sanofi-Synthelabo is paid as inventor of the two molecules, a royalty
      based on all sales generated by these products. This royalty is recorded
      as a reduction in cost of goods sold.

      As co-developers of the products, Sanofi-Synthelabo and BMS each receive
      equal development royalties from their two licensees which have been
      responsible, since 1997, for marketing the products using their local
      distribution network, composed of the affiliates of both groups. These
      licensees operate in two separate territories: (i) Europe, Africa and
      Asia, under the operational management of Sanofi-Synthelabo; and (ii) the
      rest of the world (excluding Japan), under the operational management of
      BMS. In Japan, Sanofi-Synthelabo has granted a license to BMS and
      Shionogi, a Japanese pharmaceutical company.

      The products are marketed in different ways in different countries.

      Co-promotion consists of a pooling of sales resources under a single brand
      name. Co-promotion is preferably achieved through contracts or through
      appropriate tax-transparent legal entities. Each partner records directly
      its share of taxable income.

      Co-marketing consists of separate marketing of the products by each local
      affiliate using its own name and resources under different brand names for
      the product.

      In certain countries of Eastern Europe, Africa, Asia, Latin America and
      Middle East, the products are marketed on an exclusive basis, either by
      Sanofi-Synthelabo or by BMS.

      In the territory managed by Sanofi-Synthelabo, operations are recognized
      by the Group as follows:

(i)   Co-promotion is used in most of the countries of Western Europe and Asia
      (excluding Japan) for both products, and in Portugal for irbesartan
      (Aprovel(R)/Avapro(R)/Karvea(R)). The legal entities used are partnerships
      ("societes en participation") or other tax-transparent entities, which are
      majority-owned by and under the operational management of the Group.
      Sanofi-Synthelabo recognizes all the revenue associated with the sale of
      the drugs, as well as the corresponding expenses. The share of net income
      reverting to BMS subsidiaries is recorded in "Other operating
      income/(expense), net".

(ii)  Co-marketing is used in Germany, Italy, Spain and Greece for both
      products, and in Portugal for clopidogrel (Plavix(R)/Iscover(R)).
      Sanofi-Synthelabo recognizes revenues and expenses generated by its own
      operations.

(iii) In Eastern Europe, Africa, Asia and the Middle East, where products are
      marketed exclusively by Sanofi-Synthelabo, the Group recognizes revenues
      and expenses generated by its own operations.

      In the territory managed by BMS, operations are recognized by the Group as
      follows:

(i)   Co-promotion is used in the United States and Canada through entities
      which are majority-owned by and under the operational leadership of BMS.
      Sanofi-Synthelabo does not recognize revenues; rather, it invoices the
      entity for its promotion expenses, accounts for royalties in gross profit
      and records its share of net income in "Other operating income/(expense),
      net".

(ii)  Co-marketing is used in Brazil, Mexico, Argentina, Colombia and Australia.
      Sanofi-Synthelabo recognizes revenues and expenses generated by its own
      operations.

(iii) In certain other countries of Latin America, where products are marketed
      exclusively by Sanofi-Synthelabo, the Group recognizes revenues and
      expenses generated by its own operations.

      The presentation of these transactions in the Sanofi-Synthelabo financial
      statements, in accordance with the legal nature of the agreements, results
      in the inclusion of Sanofi-Synthelabo's share of the results of operations
      in its consolidated operating profit and consolidated income before tax
      and exceptional items.

C.    SIGNIFICANT INFORMATION ON THE PRESENTATION OF THE FINANCIAL STATEMENTS
      FOR THE SIX MONTHS ENDED JUNE 30, 2003

      The three main acquisitions during the period were:

      -     Acquisition on April 16, 2002 of the 51% interest held by
            Pharmacia-Searle in the Lorex Pharmaceuticals joint venture (note
            C.2). With effect from this date, Sanofi-Synthelabo has been
            entitled to 100% of this entity's profits.

      -     Acquisition on January 1, 2002 of 100% of Institut Medical Algerien.

      -     The Group also acquired the minority interests held by third parties
            in two companies in India and Greece.

      The acquisitions made during the period resulted in the recognition of
      goodwill with a gross value of 13 million euros as of December 31, 2002.

      Divestitures

      There were no significant divestitures in the year ended December 31,

      The Fujisawa Sanofi-Synthelabo (Japan) joint venture is proportionately
      consolidated at a rate of 51%, in order to reflect new agreements that
      took effect in 2002. This entity was accounted for using the full
      consolidation method at a rate of 51% in the year ended December 31, 2001.

      Acquisitions of property, plant and equipment relate mainly to industrial
      facilities (chemicals and drugs manufacturing) and to research sites. The
      accelerated level of investment in property, plant and equipment from 2002
      is related to increases in production capacity for new products.

      During the first half of 2003, acquisitions of intangible assets relate
      either to softwares or to pharmaceutical products.

      In 2002, they mainly comprised the purchase of Ambien rights in the United
      States pursuant the acquisition of the 51 % interest of Pharmacia-Searle
      in Lorex Pharmaceuticals and payment of the balance for the rights to
      Avapro in the United States.

                                         ========           ========


      Following the merger of Sanofi and Synthelabo, the Group was in dispute
      with its co-shareholders in the Yves Rocher Group, who rejected the
      registration in the name of the merged entity Sanofi-Synthelabo of the
      Group's shares in Financiere des Laboratoires de Cosmetologie Yves Rocher
      and Laboratoires de Biologie Vegetale Yves Rocher. They had previously
      been held by Sanofi.

      The judgement dated January 10, 2001 concluded the following :

      -     Sanofi-Synthelabo rights in Financiere des Laboratoires de
            Cosmetologie Yves Rocher have been restored.

      -     Laboratoires de Biologie Vegetale Yves Rocher were given the option
            to repurchase Sanofi-Synthelabo's investment in their capital. This
            acquisition was finalized in December 2001.

      After this sale, and based on available information, the Group owns 39.1 %
      of the Financiere des Laboratoires de Cosmetologie Yves Rocher, the
      holding company, which in turn holds 51.3 % of Laboratoires de Biologie
      Vegetale Yves Rocher. Consequently, the Group had an indirect financial
      interest of 20.1% in the Yves Rocher Group.


      During the first six months of 2001, both Sanofi-Synthelabo and Financiere
      des Laboratoires de Cosmetologie Yves Rocher appealed separately to the
      highest procedural court in France ("Cour de Cassation") on these
      judgements. These appeals were rejected on May, 6 2003.


C.4.  CASH AND CASH EQUIVALENTS

      Cash and cash equivalents in the consolidated statements of cash flows
      includes available liquid assets, including short-term investments and
      deposits and cash. Sanofi-Synthelabo's treasury shares are excluded from
      cash. As of June 30, 2003, June 30, 2002 and December 31, 2002, the Group
      held 599 million, 636 million and 623 million euros respectively of its
      issued common shares in treasury (Note C.5.3).

C.5.1. SHARE CAPITAL

      The share capital comprises 732,494,621 shares with a par value of 2 euros
      per share.

C.5.2. ADJUSTMENTS TO SHAREHOLDERS' EQUITY RELATED TO THE MERGER BETWEEN SANOFI
      AND SYNTHELABO

      In 2003 and 2002, shareholders' equity were adjusted due to the merger
      between Sanofi and Synthelabo in an amount of 1 million and 59 million
      euros, respectively.

      These adjustments consist of the unused portion of provisions, initially
      recorded in the opening balance sheet, which resulted from favourable
      changes in circumstances during the period.

      These adjustments are summarized as follows :



(in millions of euros)                                                                     6 months ended       Year ended

      In 2002, the change in provisions for risks and deferred income taxes
      related mainly to the settlement of tax litigation, primarily in France
      and the United States.


C.5.3. SANOFI-SYNTHELABO SHARES

      In 2002 and 2003, the Group proceeded with a policy of purchasing its own
      shares with a view to holding, selling, transferring or canceling them.
      The share purchase program involves up to 10% of Sanofi-Synthelabo's share
      capital as authorized by the Annual General Meetings of May 22, 2002 and
      May 19, 2003. The shares purchased are netted off shareholders' equity at
      purchase price. Gains and losses on transactions in these shares, net of
      taxes, are also taken to shareholders' equity.

      Under this plan, the Group repurchased 13,940,301 shares in 2003 for 688
      million euros. As at June 30, 2003, the Group held 30,352,096 treasury
      shares, representing 4.14% of capital and amounting to 1,650 million
      euros.

      Moreover, the Group held 13,775,213 treasury shares with a net value of
      599 million euros after a charge to provision for impairment of 20 million
      euros in the six months to June 30, 2003 and after a charge to provision
      for impairment of 46 million euros in the year to December 31, 2002. These
      shares are included in "Short-term investments and deposits". These
      treasury shares represent 1.88% of the capital and are mainly allocated to
      employee stock option plans

* Reversals mainly due to settlements of tax audits.

      The Group is involved in a number of legal proceedings and claims. These
      include commercial and intellectual property litigation, tax audits and
      other matters relating to the normal conduct of its business.

      Provisions for tax exposures are recorded if the Group considers that the
      tax authorities might challenge a tax position taken by the Group or a
      subsidiary.

      An assessment of these risks has been performed with the assistance of the
      Group's legal advisers, and provisions have been recorded where
      circumstances required.

      The tax charge for the six months to June 30, 2003 is 458 million euros
      primarily related to current income taxes except for taxes on gains/losses
      on disposal. For the six months to June 30, 2002, the tax charge of 313
      million euros was also primarily related to current income taxes except

      As from January, 1 2002, the Group fully consolidates Lorex
      Pharmaceuticals. Income before tax and exceptional items includes all of
      the profits and losses of this company, including the share of net income
      reverting to Pharmacia-Searle for the period from January 1, 2002 through
      April 15, 2002. As Lorex is a tax transparent entity, the "Income taxes"
      line includes only the portion of the tax related to the profit share
      attributed to the Group. This results in a 1% reduction of the effective
      tax rate for 2002 full year and in a 3% reduction for the first six months
      of 2002.

      The "Other" line includes the difference between the French tax rate and
      the tax rate applicable in other countries and the impact of reestimating
      certain of the group's tax exposures.


C.8.  MINORITY INTERESTS

      As of June 30, 2002 and December 31, 2002, minority interests mainly
      comprise the share in the net income of Lorex Pharmaceuticals reverting to
      Pharmacia-Searle for the period from January 1, through April 15, 2002.


C.9.  SEGMENT INFORMATION

      The Group operates in one significant business segment - the research and
      development, production and sale of pharmaceutical products.

      The Group mainly operates in three geographical segments - "Europe", "the
      United States" and "Other countries".

      The table below presents net sales, operating profits, total assets and
      long-lived assets by geographical segment. Net sales and operating profit
      are allocated based on the location of the end customer. Total assets and
      long-lived assets are allocated based on the location of the subsidiary.
