MEDIA RELEASE       o      COMMUNIQUE AUX MEDIAS      o       MEDIENMITTEILUNG


Novartis clarifies position regarding Aventis

Basel, 23 March 2004 - Following a second request from the French market
authority (AMF) to clarify its position regarding Aventis, Novartis confirmed
today that it had completed its feasibility study on a potential combination
with Aventis. This study concluded that a business case is viable.

A working hypothesis included a potential spin-off of non-core Aventis and
Novartis products into a new entity that would preserve jobs, specifically in
France and Germany, creating a pharmaceutical company with product development,
licensing and commercial operations including manufacturing.

Although the business case looks viable, the negative attitude of the French
Government has influenced Novartis' consideration to a point that it will only
enter into a negotiation phase if formally invited by the Aventis Supervisory
Board and if the French Government assumed a neutral position.

The company stated that neither negotiations nor discussions about price have
taken place.

Novartis AG (NYSE: NVS) is a world leader in pharmaceuticals and consumer
health. In 2003, the Group's businesses achieved sales of USD 24.9 billion and a
net income of USD 5.0 billion. The Group invested approximately USD 3.8 billion
in R&D. Headquartered in Basel, Switzerland, Novartis Group companies employ
about 78,500 people and operate in over 140 countries around the world.
