Biovitrum and Amgen Announce Close of Product Acquisition Deal



Biovitrum to be Global Marketer for Kineret®, Kepivance® and Stemgen®

STOCKHOLM, Sweden- December 16, 2008.  Biovitrum AB (publ)  (STO:BVT)
today announced the  closing of  an agreement, signed  with Amgen  on
September 12, 2008,  under which Biovitrum  has obtained a  worldwide
exclusive license  to Kineret®  (anakinra) for  its current  approved
indication, and has acquired from Amgen global rights to the marketed
biologic therapeutic products  Kepivance®  (palifermin) and  Stemgen®
(ancestim). In 2007, the three  products generated combined sales  of
nearly MUSD 70.

Biovitrum's payment to Amgen is MUSD 117 of which MUSD 13 was paid at
signing on September 12. The remaining MUSD 104 has been paid in cash
(MUSD 34 in cash, and MUSD 50 out of an external debt facility of  in
total MSEK 600), and MUSD 20 in new equity issued to Amgen (3,768,515
ordinary  Biovitrum  shares).   In  addition,   after  Kineret®   and
Kepivance® have reached certain  cumulative net sales Biovitrum  will
pay one-time milestones to Amgen.

The agreement includes Biovitrum's acquisition of an inventory of the
three products. Biovitrum will also assume responsibility for several
ongoing Kepivance®  clinical studies,  the costs  of which  Biovitrum
will absorb within its current R&D budget.

Biovitrum also has the right  to develop a modified anakinra  product
for use in  orphan indications as  well as gout  and pseudo gout.  If
Biovitrum develops and commercializes a modified version of anakinra,
Amgen will receive single digit percentage royalties."By closing this exciting deal with Amgen, our long time partner,  we
have made a transformative move for Biovitrum. Our new products  will
add substantial value  to our  top line,  and give  rise to  earnings
contribution, as well as lead  to additional cash flow," said  Martin
Nicklasson, CEO of Biovitrum. "In addition to three new products,  we
now have the necessary infrastructure in place to fully leverage  the
value of these biotechnology therapeutics. Beginning December 16th we
will offer  these  unique  products to  patients  in  North  America,
Europe, Australia, and New Zealand." Nicklasson added.

About Stemgen® (ancestim)
When treating patients for cancer with high doses of chemotherapy the
different blood  cells  may be  injured  .  The cells  must  then  be
effectively replaced inorder to rapidly  restore the function of  the
blood. Before starting  chemotherapy treatment, Stemgen  is given  in
combination with an other pharmaceutical, Neupogen®, to the  patient.
After several days of this  treatment the patient's progenitor  cells
from the blood are  collected before the  high doses of  chemotherapy
and then given back afterwards.  The combined treatment with  Stemgen
and Neupogen, both  blood cell growth  factors, will stimmulate  bone
marow to produce extra progenitor cells for collection.
Healthcare professionals should refer to national labeling texts, and
not the information above.
