BRISTOL-MYERS SQUIBB AND MERCK ANNOUNCE GLOBAL DEVELOPMENT AND
COMMERCIALIZATION ALLIANCE FOR MURAGLITAZAR, A NOVEL COMPOUND FOR
DIABETES

NEW YORK, NEW YORK and WHITEHOUSE STATION, NEW JERSEY (April 28, 2004) --
Bristol-Myers Squibb Company (NYSE: BMY) and Merck & Co., Inc. (NYSE:MRK)
today announced that they have entered into a global collaborative agreement
for muraglitazar, Bristol-Myers Squibb's dual PPAR (peroxisome
proliferator-activated receptor) agonist, currently in Phase III clinical
development for use in treating both blood glucose and lipid abnormalities in
patients with type 2 diabetes.

Under the terms of the agreement, Bristol-Myers Squibb will receive a $100
million upfront payment and $275 million in additional payments based upon the
achievement of certain regulatory milestones. Bristol-Myers Squibb and Merck
will jointly develop the clinical and marketing strategy for muraglitazar and
share equally in future development and commercialization costs. Both
companies will co-promote the product to physicians on a global basis, and
Merck will receive payments based on net sales levels. In addition, Merck
received rights to development and commercialization for a back-up compound to
muraglitazar, which is entering Phase II clinical trials for the treatment of
diabetes. Further details of the agreement were not disclosed.

"This collaboration with Merck reflects our new corporate strategy, which will
build long-term growth by focusing on critical disease areas such as diabetes
and will optimize the value of all of our assets," said Peter R. Dolan,
chairman and chief executive officer, Bristol-Myers Squibb. "As we move
forward in implementing this new strategy, Bristol-Myers Squibb will center
our efforts on reaching specialists and high prescribing primary care
physicians. The company will also selectively develop strategic partnerships,
such as this one, that enable us to realize the full potential of our
promising pipeline."

Muraglitazar was discovered and developed by Bristol-Myers Squibb as part of
an intensive internal research program to deliver innovative medicines for
patients with type 2 diabetes. The dual PPAR agonist works by targeting both
alpha and gamma PPAR receptors and, as a result of this dual agonist activity,
muraglitazar is being tested to potentially provide both blood sugar control
and improved lipid management in patients with type 2 diabetes.

As announced previously, muraglitazar is expected to be submitted within the
next 9-12 months for U.S. regulatory approval. If approved, muraglitazar has
the potential to be the first of the novel class of drugs known as dual PPAR
agonists to be approved for marketing in the U.S.

"We are very proud to be working with Bristol-Myers Squibb as their partner
for the development and commercialization of muraglitazar, which has the
potential to represent a true advance in the treatment of type 2 diabetes,"
said Raymond V. Gilmartin, chairman, president and chief executive officer,
Merck. "We believe that the combined scientific and marketing talents of our
two companies will help advance this potential new medicine.




"Through the discussions that have already taken place between our two teams,
we believe that this will be a productive relationship. This partnership is
consistent with Merck's strategy to develop external alliances that complement
our substantial internal research effort," Gilmartin added.

Type 2 diabetes, often known as adult-onset diabetes, occurs when the body
does not produce enough insulin to normally regulate blood sugar levels or
when the body develops resistance to the effects of insulin. Type 2 diabetes
is a growing public health problem that today affects 17 million adult
Americans and is now the sixth leading cause of death in this country,
according to the U.S. Centers for Disease Control (CDC). The condition is
associated with older age, obesity, a family history of diabetes and physical
inactivity. Worldwide, type 2 diabetes affects an estimated 40 million people
in major pharmaceutical markets today, a number that is expected to more than
double to 90 million people by 2015.

"Bristol-Myers Squibb and Merck are well established as leaders in the fields
of type 2 diabetes and cardiovascular medicine," Dolan said. "This
collaboration will enable Bristol-Myers Squibb and Merck to leverage the
breadth of R&D and commercial capabilities and resources in both type 2
diabetes and cardiology to realize the full potential of muraglitazar. We are
excited about this partnership and we are dedicated to combining our extensive
resources to advance the development and commercialization of muraglitazar as
a potential new treatment option for the millions of patients around the world
with type 2 diabetes."
