Biovitrum strengthens its relationship with Wyeth - Starts to co-promote
BeneFIX® in the Nordic countries

Biovitrum today announced it has entered into a new agreement, effective August
8, 2007, with Wyeth (NYSE: WYE) to co-promote BeneFIX®, nonacog alfa
(Recombinant Coagulation Factor IX) for hemophilia B, in the Nordic countries
(Denmark, Finland, Iceland, Norway and Sweden).  With the exception of these
countries, Wyeth markets BeneFIX® around the world.

Under the terms of the agreement, Biovitrum will receive a commission on BeneFIX
sales, including an additional incentive if certain sales targets are exceeded,
for a period of up to five years, with possible one year extensions thereafter.
BeneFIX uses recombinant DNA technology to replace clotting factor IX to stop or
prevent bleeding in people with hemophilia B who do not have enough factor IX of
their own. Hemophilia B is a rare, inherited blood clotting disorder.  People
with hemophilia B are deficient in factor IX which is vital in the clotting
mechanism to prevent bleeding.  Hemophilia B is characterized by spontaneous
hemorrhages or prolonged bleeding, typically into joints and soft tissue. 
Patients with hemophilia B are dependent on protein replacement therapy with
factor IX.

Biovitrum has been very successful in the Nordic market for blood diseases and
will by this agreement strengthen its position with this additional product. 

Comments by Martin Nicklasson, CEO of Biovitrum:

"Blood diseases and especially hemophilia is an area of great strategic
importance for us.  I am delighted that Wyeth has chosen Biovitrum as a partner
in the Nordic region for BeneFIX.  It adds to our already strong relationship
with Wyeth in the hemophilia area and it confirms our ability to deliver value
in the market.  It also demonstrates that we are an attractive partner for
co-promoting other pharmaceutical companies products in the Nordic market.  Our
commercial activities within this field will thereby continue to grow and
generate additional revenues."

Biovitrum manufactures recombinant factor VIII used in Wyeth's ReFacto® for the
treatment and prophylaxis of hemophilia A.  Biovitrum receives royalties on
Wyeth's global ReFacto® sales as well as co-promotion revenues from the sales of
ReFacto in the Nordic countries.


About BeneFIX
BeneFIX is indicated for the treatment and prophylaxis of bleeding in patients
with hemophilia B (congenital factor IX deficiency).

Allergic-type hypersensitivity reactions, including anaphylaxis, have been
reported for all factor IX products. Frequently, these events have occurred in
close temporal association with the development of factor IX inhibitors.
Patients should be informed of the early symptoms and signs of hypersensitivity
reactions including hives, generalized urticaria, chills (rigors), flushing,
angioedema, chest tightness, dyspnea, wheezing, faintness, hypotension,
tachycardia, and anaphylaxis. If allergic or anaphylactic reactions occur,
administration of BeneFIX® should be stopped immediately, and appropriate
medical management should be given, which may include treatment for shock.
Patients should be advised to discontinue use of the product and contact their
physician and/or seek immediate emergency care, depending on the type/severity
of the reaction, if any of these symptoms occur. 

Nephrotic syndrome has been reported following immune tolerance induction with
factor IX products in hemophilia B patients with factor IX inhibitors and a
history of allergic reactions to factor IX. The safety and efficacy of using
BeneFIX® for immune tolerance induction has not been established.

Since the use of factor IX complex concentrates has historically been associated
with the development of thromboembolic complications, the use of factor
IX-containing products may be potentially hazardous in patients with signs of
fibrinolysis and in patients with disseminated intravascular coagulation.

About ReFacto
ReFacto moroctocog alfa (Recombinant Coagulation Factor VIII) is indicated for
the control and prevention of hemorrhagic episodes and for surgical prophylaxis
in patients with hemophilia A (congenital factor VIII deficiency or classic
hemophilia).

ReFacto is indicated for prophylaxis to reduce the frequency of spontaneous
bleeding episodes in patients with hemophilia A.

ReFacto does not contain von Willebrand factor and therefore is not indicated in
von Willebrand's disease.

As with the intravenous administration of any protein product, adverse reactions
may include headache, fever, chills, flushing, nausea, vomiting, tiredness, or
symptoms of allergic reactions.  The remote possibility exists for
hypersensitivity to non-human mammalian proteins.
