In the fourth quarter of 2005, sanofi-aventis generated net sales of €7,007 million, up 4.8%. Exchange rate movements had a favorable effect of 3 points, and changes in Group structure a negative effect of 0.8 of a point. After allowing for these impacts, reported-basis growth was 7.0%. 2005 full-year net sales were €27,311 million, up 9.3%. Exchange rate movements had a neutral impact over the year as a whole, while changes in Group structure had a negative effect of 0.9 of a point. After allowing for these impacts, reported-basis growth was 8.4%. Net sales by business segment Net sales reported by sanofi-aventis comprise net sales generated by the pharmaceuticals business and net sales generated by the human vaccines business. Pharmaceuticals Fourth-quarter net sales for the pharmaceuticals business, which were significantly affected by the arrival of Allegra® generics in the United States, rose by 1.6% to €6,364 million. Net sales of the top 15 products were up 6.8% at €4,112 million, representing 64.6% of pharmaceuticals net sales, against 61.5% for the same period in 2004. Excluding the impact of generics of Allegra® and Amaryl® in the United States, growth for the top 15 products would have reached 15.7%. Full-year pharmaceuticals net sales for 2005 were €25,249 million, a rise of 8.1%. Net sales of the top 15 products advanced by 14.0% to €16,188 million, representing 64.1% of pharmaceuticals net sales, versus 60.8% in 2004.

This fall was due partly to generics of DDAVP® (down 79.4%) and Arava® (down 79.2%) in the United States, and partly to price reductions in France. Full-year 2005 net sales of other pharmaceutical products were 1.1% down on prior year at €9,061 million. Human Vaccines Fourth quarter net sales for the Human Vaccines business were up 50.2% at €643 million. Over 2005 as a whole, the business reported net sales of €2,062 million, an increase of 26.9% on a comparable basis. The vaccines business was significantly boosted by three successful launches in the United States during 2005: Menactra®, launched in March 2005 for the prevention of meningococcal meningitis, posted net sales of €179 million. After a fine 2005 third quarter, helped by the vaccination campaigns at the start of the American school year, Menactra® achieved solid sales during the final quarter. The business shipped more than 3 million doses in 2005 and plans to increase capacity to nearly 6 million doses in 2006. A new facility, with a capacity of at least 20 million doses, is scheduled to be operational in 2008. Decavac® (preservative-free adult booster against diphtheria and tetanus), launched in the United States in January 2005, recorded net sales of €180 million. AdacelTM (adolescent and adult tetanus-diphtheria-whooping cough-Tdap booster) was launched in the United States in July 2005 achieving sales of €26 million. In Q4, Adacel received a strong recommendation from the ACIP which is expected to expand the diphtheria and tetanus market. The 2005 influenza vaccination season in the United States was the most successful in the history of our US vaccines business, with 64 million doses sold. This was primarily due to extending the “normal” immunization season into November and December to meet market demand and implementing government contracts for strategic reserves of current season supply. At the end of 2005, preliminary results from trials conducted in France with the first vaccine candidate with an adjuvant for the pre-pandemic H5N1 influenza strain demonstrated a good immune response in a significant number of volunteers. € millionQ4 2005 net salesChange on a comparable basis2005 net salesChange on a comparable basis Polio/Whooping Cough/Hib Vaccines113+19.0%522+3.2% Adult Booster Vaccines59+112.7%270+58.8% Influenza Vaccines334+50.5%671+28.6% Travel Vaccines47+28.4%176+3.6% Meningitis/Pneumonia Vaccines 47+176.5%256+137.0% Other Vaccines4348.3%167+12.1% Total643+50.3%2,062+26.9% Sanofi Pasteur MSD, the joint venture with Merck & Co in Europe, generated fourth-quarter sales of €161 million, down 5.5% on a reported basis. In 2005 as a whole, the joint venture generated sales of €688 million, up 5.7% on a reported basis. Sales were adversely affected by the temporary suspension in September of marketing approval for Hexavac® (net sales of €43 million in 2005, vs. €86 million in 2004). Excluding Hexavac®, sales growth at Sanofi Pasteur MSD would have been 14.1% on a reported basis. These sales are not consolidated by sanofi-aventis.

In Germany, price pressure intensified, due largely to the extension of the reference price system to new therapeutic classes. In France, sales were adversely affected by the healthcare system reforms and by price reductions. Over 2005 as a whole, sales growth in Europe was boosted by a dynamic performance across the entire portfolio, especially Lantus® (up 40.5%), Eloxatin® (up 31.4%), Taxotere® (up 20.1%) and Plavix® (up 20.5%). Fourth-quarter sales growth in the United States, affected by competition from generics of four products, was 2.6%. Excluding the impact of these four products, fourth-quarter sales growth would have reached 21.2%. Over the year as a whole, net sales rose by 11.5%; excluding the impact of the four products affected by competition from generics, 2005 full-year sales growth would have been 17.4%. In other countries, sales growth again accelerated in the fourth quarter, reaching 9.5%. Developed sales Developed sales give an indication of the overall presence of sanofi-aventis products in the market. 2005 full-year developed sales reached €30,778 million, up 9.7%.

Product sales have benefited from a steady increase in the duration of treatment and by increased penetration across all markets. In January 2006, the FDA granted a priority review for a supplemental new drug application for Plavix® for the treatment of patients with acute ST-segment elevation myocardial infarction. The results of the CHARISMA study are to be presented to the American College of Cardiology (ACC) in March 2006. Plavix®, which has just been approved in Japan for the reduction of recurrence after ischemic cerebrovascular disorder, is due to be launched there in the second quarter of 2006. 4 IMS NPA 3 channels –2005 Developed sales of Aprovel®/Avapro®/Karvea®: € million Q4 2005 Change on a comparable basis 2005Change on a comparable basis Europe203+10.3%789+11.4% United States139+9.4%458+2.2% Other countries 86+8.9%312+13.0% Total428+9.7% 1,559+8.9% Fourth-quarter developed sales of Aprovel®/Avapro®/Karvea® totaled €428 million, a rise of 9.7%.

Growth of the product continues to be driven by the extension of its use in medical prophylaxis, and by the conversion from non-fractionated heparins. The results of the VITAE study showed that venous thromboembolic disease remains a major cause of mortality in the United States with over 300,000 patients dying every year, only 7% of whom had been diagnosed and treated. The results of the EXTRACT study into acute coronary syndromes with ST-segment elevation are due to be announced to the American College of Cardiology (ACC) in March 2006. In the fourth quarter, Allegra®, which since September has faced competition from generics in the United States, generated net sales of €160 million (down 58.5%), including €87 million (down 72.2%) in the United States. An authorized generic version of the product was launched in the United States by Prasco Laboratories on September 14, 2005, this version accounted for 42.8% of generic fexofenadine prescriptions in December 2005. In Japan, Allegra® achieved net sales of €205 million in 2005, an increase of 34.8%. In the fourth quarter, Taxotere®, recorded an excellent performance in Europe. In the United States, the product returned to growth in 2005, but still faces a tough competitive environment due largely to generics of paclitaxel. The main growth drivers for Taxotere® are its indications as an adjuvant treatment for breast cancer and a treatment for non hormone-resistant prostate cancer, plus potential new indications. In early-stage HER-2 positive breast cancer patients, regimens combining Taxotere® and Herceptin®, with or without doroxubicin, showed a significant improvement in disease-free survival rates (BCIRG 006 study – interim analysis). In the non-doroxubicin arm of the study, the clinical benefit was obtained with reduced toxicity. The product is well placed to obtain two new potential indications, in advanced gastric cancer and head/neck cancer. At end 2005, the FDA granted a priority review for a supplemental new drug application for a new indication for Taxotere® in association with the standard treatment (cisplatin and 5-fluorouracil) in advanced gastric cancer. A new drug application for Taxotere® in the treatment of head and neck cancer is due to be filed in 2006. Fourth-quarter net sales of Ambien®/Ambien CRTM in the United States rose by 23.5% to €383 million, lifted by an excellent performance from Ambien CRTM which since October 2005 has been promoted by over 3,000 medical reps. To end December, prescriptions of Ambien CRTM represented some 14,5%5 of total prescriptions for the Ambien® family. Total market share of the Ambien® family has increased to 44.7%6 in December. The Group has also received a Written Request from the US healthcare authorities for pediatric studies of Ambien®. In Japan, sales of Myslee® (developed sales) rose by 20.1% in 2005 to €109 million. In 2005, Myslee® attained a market share of 27.0%7, an increase of more than 3 points. In the fourth quarter, Eloxatin® recorded another very good performance. The product gained market share as an adjuvant treatment for colorectal cancer in Europe and the United States (57.2%8 US market share – stage III patients). In France and the United States, the new formulation now accounts for over 80% of Eloxatin® use. The Group plans to roll out this formulation in a number of European countries in 2006. 5 IMS NPA 2 channels – Weekly 6 IMS NPA 3 channels – December 2005 7 IMS Retail + Hospital (value) MAT November 2005 8 Source: Intrinsiq Research – Rolling quarter – November 2005 In the fourth quarter, Lantus®, the leading insulin in the market and the only insulin analog to provide 24-hour peakless coverage, continued to perform excellently, with net sales up 45.0% at €345 million. In 2005, Lantus® achieved blockbuster status, with net sales advancing by 47.5% to €1,214 million. In the United States, the product’s market share reached 30.4%6 in December 2005. Since the start of the fourth quarter, Amaryl® has been facing competition from generics in the United States, resulting in a fall of 28.6% in net sales of the product during the period (with US sales down 86.2%). An authorized generic version of Amaryl® was launched by Prasco Laboratories at the start of the fourth quarter, and accounted for 29.6% of glimepiride prescriptions in December 2005.

Comparable net sales: When we refer to the change in our sales on a “comparable” basis, we mean that we exclude the impact of exchange rate movements and changes in Group structure (acquisitions and divestments of interests in entities and rights to products, and changes in consolidation method 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 consolidation method, the prior period is recalculated on the basis of the method used for the current period.

Sanofi-aventis believes that eliminating these impacts from net income gives investors a better understanding of the underlying economic performance of the combined Group.
