Final Results of the Subsequent Offer Period of Acorda Therapeutics' Tender Offer for All of the Shares, American Depositary Shares, Stock Options, Share Units and Warrants in Biotie Therapies Corp.

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN OR INTO CANADA, JAPAN, AUSTRALIA, SOUTH AFRICA, HONG KONG OR IN ANY OTHER JURISDICTION IN WHICH THE TENDER OFFER WOULD BE PROHIBITED BY APPLICABLE LAW.

The subsequent offer period under the voluntary public tender offer by Acorda Therapeutics, Inc. (Nasdaq:ACOR) ("Acorda" or the "Offeror") to purchase all of the issued and outstanding shares ("Shares"), American Depositary Shares ("ADSs"), stock options, share units and warrants (such securities, collectively, the "Equity Interests") in Biotie Therapies Corp (Nasdaq Helsinki: BTH1V; Nasdaq:BITI) ("Biotie" or the "Company") that are not owned by Biotie or any of its subsidiaries (the "Tender Offer") commenced on 14 April 2016 and expired on 28 April 2016 (the "Subsequent Offer Period").

According to the final results of the Subsequent Offer Period, 38,419,864 Shares and 58,121 ADSs were tendered during the Subsequent Offer Period, representing, together with the other Equity Interests tendered in the Tender Offer during the initial offer period, approximately 97.36 percent of all the shares and votes in Biotie on a fully-diluted basis as defined in the terms and conditions of the Tender Offer.

The Shares and ADSs tendered during the Subsequent Offer Period represent approximately 4.39 percent of all the shares and votes in Biotie (excluding treasury shares held by Biotie). Together with the Shares and ADSs tendered during the initial offer period, these Shares and ADSs represent approximately 96.77 percent of all the shares and votes in Biotie (excluding treasury shares held by Biotie). By exercising the other Equity Interests tendered during the initial offer period for the subscription of Biotie shares, the Offeror could increase its holding to approximately 97.42 percent of all the shares and votes in Biotie (excluding treasury shares held by Biotie).

The Offeror has accepted all the Shares and ADSs validly tendered during the Subsequent Offer Period. The offer consideration has been paid to those holders of Shares and ADSs who validly accepted the Tender Offer by the first acceptance date of 21 April 2016 under the Subsequent Offer Period, and will be paid on or about 4 May 2016 to those holders of Shares and ADSs who validly accepted the Tender Offer by the second acceptance date of 28 April 2016 under the Subsequent Offer Period.

The Offeror’s intention is to acquire all the remaining Shares and ADSs in Biotie. As the Offeror’s ownership in Biotie has exceeded nine-tenths (9/10) of the Shares and voting rights in Biotie through the Tender Offer, the Offeror has filed an application with the Redemption Committee of the Finland Chamber of Commerce to initiate compulsory redemption proceedings for the remaining Biotie Shares under the Finnish Companies Act. The Offeror may purchase Shares and ADSs in Biotie also in public trading on Nasdaq Helsinki Ltd. and Nasdaq Stock Market LLC or otherwise at a price not exceeding the offer price of EUR 0.2946 per Share and EUR 23.5680 per ADS offered in the Tender Offer.

The Offeror intends to cause the Shares of Biotie to be delisted from Nasdaq Helsinki Ltd. and the ADSs to be delisted from Nasdaq Stock Market LLC and deregistered under the United States Securities Exchange Act of 1934 as soon as permitted and practicable under applicable laws.
