Paris, France - January 29, 2010 - Sanofi-aventis (EURONEXT: SAN and NYSE: SNY)

consumer healthcare joint venture. Subject to certain conditions precedent and
to regulatory approvals, sanofi-aventis is to obtain a majority equity stake in

The intended sanofi-aventis-Minsheng joint venture will primarily focus on
Vitamins and Mineral Supplements (VMS), the largest consumer healthcare segment
in China, where Minsheng has established a strong presence with its flagship
multivitamin brand of 21 Super-Vita(r). Globally, sanofi-aventis is the 5th
largest consumer healthcare company, and the French group continues to expand
its presence through mergers and acquisitions. Most recently, sanofi-aventis
announced its planned acquisition of Chattem Inc., a leading manufacturer and
marketer of branded consumer healthcare products, toiletries and dietary
supplements in the United States, a country that represents 25 percent of the
worldwide consumer healthcare market.

"We are pleased to take a significant step toward establishing the new consumer
healthcare joint venture with Minsheng, our long-standing partner", said
Hanspeter Spek, President, Global Operations, sanofi-aventis. "Combined with 
our leadership position in vaccines, we will continue to contribute to 
preventative healthcare in China. Entering the world's second largest consumer 
healthcare market is also a strategic move for sanofi-aventis to consolidate 
its position in consumer healthcare", added Hanspeter Spek, who presided over 
the signing ceremony together with Minsheng and senior leaders of Hangzhou 
municipal government.

"We are equally excited about the prospect of forming the new consumer
healthcare joint venture with sanofi-aventis, after more than ten years of
successful partnership." said Zhu Fujiang, Chairman of Minsheng Pharmaceutical
Co., Ltd. He added: "Sanofi-aventis is an energetic and dynamic company. His
success with pharmaceuticals and vaccines has demonstrated his strong marketing
capability. We hope that once materialized, the new venture will revitalize our
consumer healthcare business and expand the reach of our products to bene fit
more consumers. We also hope that the new venture will serve as a platform for
us to develop more health products in order to contribute to the local economy
and meet consumer needs".

In 2008, the consumer healthcare market in China was estimated to approach 
7 billion Euro (approximately 70 billion RMB). The market is forecasted for
continued double-digit growth over the next five years, driven by favourable
market trends, such as increasing consumer affordability, government focus on
health awareness and prevention driving an already well-established trend for
self medication, and proliferation of pharmacy chains and modern trade.
