                   METTLER TOLEDO TO ACQUIRE RAININ INSTRUMENT
           -- EXPANDS POSITION IN FAST-GROWING LIFE SCIENCES MARKET --

GREIFENSEE, Switzerland and COLUMBUS, Ohio, USA - October 14, 2001 -
Mettler-Toledo International Inc. (NYSE: MTD) announced today it has agreed
to acquire Rainin Instrument, the leading manufacturer of pipetting
solutions used in pharmaceutical, biotech and medical research
applications. METTLER TOLEDO will purchase Rainin for a total consideration
of $292.2 million, of which approximately one-half will be paid in cash and
one-half in shares of common stock.

"Rainin is highly regarded in life sciences for its excellence in marketing
and its leadership in technology. Its products set world standards for
quality, accuracy and reproducibility," said Robert F. Spoerry, Chairman,
President and CEO of METTLER TOLEDO. "With its broad patent portfolio,
Rainin has truly differentiating technology in areas like electronic
pipetting, ergonomic designs for pipettes, and tip designs which meet the
exacting standards of today's research processes. We are eager to add this
company of exceptional growth and profitability and to realize the
synergies from our union."

Kenneth Rainin, President of Rainin, said, "METTLER TOLEDO serves
essentially the same customer base, with complementary products that
enhance the productivity and efficiency of research and development
processes. Its global franchise is built upon strong leadership positions,
an excellent brand name and an extensive sales and service network.
Altogether, these factors make METTLER TOLEDO an ideal partner for Rainin."

Spoerry concluded, "Our aim is to build on METTLER TOLEDO's global
infrastructure and customer relationships to rapidly extend Rainin's
leadership worldwide. This acquisition further broadens our market-leading
offering of instruments and solutions to the life sciences market and
positions us to bring greater value to our customers and shareholders."
