BIOTIE THERAPIES CORP.             STOCK EXCHANGE RELEASE      24 April 2015 at
1.35 p.m.

Notification according to Chapter 9, Section 5 of the Finnish Securities Markets
Act

Biotie Therapies Corp. (the "Company" or "Biotie") has received a notification
in accordance with Chapter 9, Section 5 of the Finnish Securities Markets Act
from Seth Klarman on behalf of himself and SAK Corporation and The Baupost
Group, L.L.C.

According to the notification, Seth Klarman is the sole owner of SAK
Corporation, the manager and controlling entity of The Baupost Group, L.L.C.,
which is the managing general partner of (i) Baupost Limited Partnership 1983 A-
1 (being the parent entity of Baupost Private Investments A-1, L.L.C), (ii)
Baupost Limited Partnership 1983 B-1 (being the parent entity of Baupost Private
Investments B-1, L.L.C.), (iii) Baupost Limited Partnership 1983 C-1 (being the
parent entity of Baupost Private Investments C-1, L.L.C), (iv) Baupost Value
Partners, L.P.-II (being the parent entity of Baupost Private Investments BVII-
1, L.L.C), (v) HB Institutional Limited Partnership (being the parent entity of
Baupost Private Investments H-1, L.L.C.), (vi) PB Institutional Limited
Partnership (being the parent entity of Baupost Private Investments P-1,
L.L.C.), (vii) YB Institutional Limited Partnership (being the parent entity of
Baupost Private Investments Y-1, L.L.C.), (viii) Baupost Value Partners, L.P.-I
(being the parent entity of Baupost Private Investments BVI-1, L.L.C), (ix)
Baupost Value Partners, L.P.-III (being the parent entity of Baupost Private
Investments BVIII-1, L.L.C.) and (x) Baupost Value Partners, L.P.-IV (being the
parent entity of Baupost Private Investments BVIV-1, L.L.C). The notification
concerns an arrangement that, if realized, would result in the below described
changes in share ownership.

The notification relates to the subscription agreement entered into on 23 April
2015 between Biotie and certain investors which is described in more detail in
the stock exchange release issued by the Company on 23 April 2015. The said
investors have agreed to invest in the Company by means of subscribing for
convertible promissory notes ("Convertible Notes") and other equity-based
instruments ("Warrants"). The issue and subscription of the Convertible Notes
and Warrants is conditional, among other things, on the granting of necessary
authorizations and election of new Board members by an Annual General Meeting of
Biotie to be held on 26 May 2015.

The convertible loan to be represented by the Convertible Notes can be converted
into new shares in the Company by their holders at any time prior to the
repayment of the Convertible Notes, which is scheduled to occur on or after 1
May 2035. Further, the Convertible Notes would automatically convert into new
shares in the Company upon completion of a proposed US public offering and
listing on the Nasdaq Global Market of American Depositary Receipts representing
the Company's shares. If the US public offering would not take place by 1 May
2016, the Company can force the conversion of the Convertible Notes at any time
thereafter. The Warrants will entitle to subscribe for shares in the Company
until 1 November 2020.

According to the notification, should the Convertible Notes and Warrants be
issued to the entities listed in Annex 1, their conversion and exercise in full
would result in shareholding in the Company as described below:
