BIOTIE THERAPIES CORP. STOCK EXCHANGE RELEASE 27 February 2013 at 9.00 a.m. 

Amendment to the release on UCB license of worldwide rights to tozadenant in Parkinson's disease
from Biotie 

With reference to the stock exchange release on 26 February 2013 at 7:00 p.m. Biotie clarifies
that the additional milestones under the revised agreement and Biotie being responsible for
conducting phase 3 development of tozadenant are not likely to have significant impact on
profitability of Biotie during the duration of the clinical development. The amended release in
its entirety may be found below.

UCB to license worldwide rights to tozadenant in Parkinson's disease from Biotie 

*Novel product in development for the treatment of people living with Parkinson's disease 
*Biotie receives USD 20 million license fee payment 
*Original agreement modified: Biotie to conduct phase 3 development 

Biotie and UCB announced today that UCB has licensed worldwide exclusive rights to Biotie's
tozadenant (SYN115), a selective inhibitor of the adenosine 2a receptor, currently in development
for the treatment of Parkinson's disease. As a result, Biotie will receive a one-time fee payment
of USD 20 million from UCB. In addition, the parties have amended their original license
agreement, such that Biotie will now conduct phase 3 development of tozadenant in return for
additional payments from UCB relating to defined development, regulatory and commercialization
milestones.

"UCB is committed to improving the lives of people with Parkinson's disease and currently provides
Neupro(R) a transdermal dopamine agonist for the symptomatic treatment of all stages of idiopathic
Parkinson's disease," said Professor Dr Iris Loew-Friedrich, Chief Medical Officer and Executive
Vice President UCB. "Biotie is a valuable partner and the decision to in-license follows the
positive top-line results of the phase 2b study. We were impressed by the performance of Biotie
and decided that they are the ideal party to continue to spearhead the development of tozadenant.
We look forward to collaborating with Biotie in the on-going clinical development. With the
addition of the novel compound tozadenant to UCB's development portfolio we should be able to
further contribute to the advancement of the treatment and care for people living with Parkinson's
disease."

The phase 2b study was a double-blind, randomized, placebo-controlled study evaluating the safety
and efficacy of tozadenant as adjunctive therapy in levodopa-treated Parkinson's patients with end
of dose wearing off. Results from the phase 2b study are expected to be presented at upcoming
medical conferences and in scientific publications. Patient enrollment in the phase 3 program is
currently planned to commence by the first half of 2015.

The original agreement between UCB and Biotie was announced in 2010. Under the terms of the
original agreement UCB will make an immediate one-time payment of USD 20 million to Biotie and
Biotie will remain eligible to a potential additional USD 340 million in future milestone
payments. Under the revised agreement, Biotie will be eligible for additional payments in the low
triple digit millions in total over the next six years based on the successful completion of
defined development, regulatory and commercialization milestones. The final amounts of the
additional payments are to be determined between the parties upon completion of the study plans in
the coming months. The additional milestone payments are likely not to significantly impact
Biotie's profitability during the duration of the clinical development. UCB and Biotie will
collaborate on the on-going clinical development and UCB will be responsible for the manufacture
and commercialization of tozadenant.

"We are thrilled with the opportunity to continue the development of tozadenant in partnership
with UCB", said Timo Veromaa, President and Chief Executive Officer of Biotie. "We are encouraged
by the vote of confidence provided to us by UCB to continue with us the development of tozadenant
and the very significant incremental financial resources that we will be given to complete the
clinical work."

About Parkinson's disease

Parkinson's disease is a chronic, degenerative neurological disease. It is commonly associated
with movement (motor) symptoms such as tremors (uncontrollable shaking), rigidity (stiffness or
muscle tensing) and bradykinesia (slowness and loss of spontaneous movement), but also commonly
causes underlying symptoms such as mood and cognitive impairment, pain, depression and fatigue.

About tozadenant (SYN115)

Tozadenant is an orally administered, selective inhibitor of the adenosine 2a (A2a) receptor being
developed initially for the treatment of Parkinson's disease. A2a receptors are expressed in high
concentration in the striatum of the brain and are thought to play an important role in regulating
motor function. Tozadenant blocks the effect of endogenous adenosine at the A2a receptors,
resulting in the potentiation of the effect of dopamine and inhibition of the effect of glutamate
at the mGluR5 receptor.
