9 August 2012

AstraZeneca and Bristol-Myers Squibb today announced that following the
successful completion of the acquisition of Amylin Pharmaceuticals by Bristol
-Myers Squibb, AstraZeneca has made an initial payment of approximately $3.2
billion to Amylin Pharmaceuticals, now a wholly-owned subsidiary of Bristol
-Myers Squibb. As previously disclosed, the payment is being made in connection
with the expansion of the diabetes alliance between AstraZeneca and Bristol
-Myers Squibb to incorporate the development and marketing of Amylin’s portfolio
of diabetes products, and profits and losses arising from the collaboration will
be shared equally.

AstraZeneca has also informed Bristol-Myers Squibb of its intention to exercise
its option to acquire certain additional governance rights over key strategic
and financial decisions regarding Amylin’s portfolio. The rights to this option
will become effective once the applicable anti-trust and competition approvals
are received by AstraZeneca. Upon the exercise of the option an additional
payment of $135 million will be made to Bristol-Myers Squibb.

Simon Lowth, Interim Chief Executive Officer, AstraZeneca, said: “We are
delighted to have successfully completed the expansion of our diabetes alliance
with Bristol-Myers Squibb through the addition of Amylin’s GLP-1 franchise,
creating a broader disease management platform for patients, physicians and
payers. We are looking forward to working with the team at Amylin to build on
their success and maximise AstraZeneca’s and Bristol-Myers Squibb’s combined
capabilities to make these innovative treatments available to diabetes patients
across the world.”

Lamberto Andreotti, Chief Executive Officer, Bristol-Myers Squibb, said: “The
completion of our acquisition of Amylin and the expansion of our diabetes
alliance with AstraZeneca will increase and strengthen our innovative portfolio
of diabetes medicines, extending its reach across the spectrum of treatment
options. We are pleased to have the opportunity to work together to build on the
innovative portfolio, state-of-the art manufacturing facilities and dedicated
customer focus that the talented people at Amylin have created.”

AstraZeneca’s share of the transaction was financed through existing cash
resources and credit facilities.
