  AstraZeneca and Abgenix announce Strategic alliance to discover and Develop
                        Antibody Therapeutics for Cancer



AstraZeneca makes $100 million upfront equity investment to broaden oncology
research scope

Abgenix to receive milestone, royalty and collaboration payments



London and Fremont, CA -AstraZeneca and Abgenix, Inc, announced today that they
have entered into a broad collaboration, license and investment alliance to
discover, develop and commercialise fully human monoclonal antibodies to treat
cancer.  The alliance involves:



*   the joint discovery and development of therapeutic antibodies for
    up to 36 cancer targets to be commercialised exclusively worldwide by
    AstraZeneca.  For these products, Abgenix will receive milestone payments at
    various stages of development and royalties on future product sales.  In
    addition, the collaboration will involve the selection and development of an
    additional pool of antibodies by Abgenix, which the companies may elect to
    further develop on an equal cost and profit sharing basis.


*   For those product candidates for which AstraZeneca holds exclusive
    commercialisation rights, Abgenix will conduct early clinical trials,
    process development and clinical manufacturing, as well as commercial
    manufacturing during the first five years of commercial sales.  AstraZeneca
    will compensate Abgenix for those activities at competitive market rates.


*   a $100 million investment by AstraZeneca in Abgenix convertible
    preferred stock, initially convertible into Abgenix common stock at $30 per
    share. Upon the achievement of certain milestones, Abgenix may also require
    AstraZeneca to invest an additional $60 million in Abgenix convertible 
    preferred stock.


AstraZeneca may select initial antibodies from Abgenix's existing preclinical
oncology portfolio and both companies will also propose additional targets for
selection.  AstraZeneca will be responsible for late stage clinical development
of the portfolio and will hold worldwide commercialisation rights for any
resulting products.  Upon commercialisation, royalties will be paid to Abgenix
on sales of products that result from the collaboration.  The royalty range will
vary from product to product based on the level of product sales.



The alliance also includes a co-development component under which Abgenix will
generate additional antibody product candidates that AstraZeneca will have the
option to co-develop with Abgenix.   The companies will share development costs
and responsibilities for any co-development candidates selected.



"This collaboration further strengthens our position at the forefront of cancer
research, allowing us to combine our oncology development expertise and leading
sales and marketing capabilities with Abgenix's expertise in the discovery,
early development and manufacture of fully human antibodies.  This alliance adds
to our proven expertise with small molecules and has the potential to
significantly broaden and strengthen AstraZeneca's oncology pipeline," said Sir
Tom McKillop, Chief Executive of AstraZeneca.



"This alliance reinforces the value of our antibody development platform and
enables the next wave of oncology products beyond our lead candidate ABX-EGF,"
said Raymond Withy, PhD, President and Chief Executive Officer of Abgenix.  "By
partnering with AstraZeneca, a global leader in oncology research and
development, we take a major step towards bringing a portfolio of highly
targeted and effective cancer drugs to patients," Withy continued.



The consummation of the collaboration and license agreement and the issuance of
the convertible preferred stock to AstraZeneca are subject to customary closing
conditions, including without limitation the expiration or termination of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended.



A conference call with executives from both companies will be held on Thursday,
October 16 at 6:00 AM PST, 2:00pm BST to discuss today's announcement.  The call
will be webcast live and available for replay on Abgenix's website at
