Tamfelt by lodging a security approved by the Arbitral Tribunal for the payment
of the redemption price and the interest accruing thereon.

Metso has today lodged the security of EUR 5.5 million approved by the Arbitral
Tribunal and, therefore, gained title to all the shares in Tamfelt in accordance
with Chapter 18, Section 6 of the Finnish Companies Act. After lodging the
security, the minority shareholders of Tamfelt being parties to the redemption
proceedings are entitled to receive the redemption price and the interest
payable thereon.The redemption price and the interest thereon is estimated to be
confirmed by the arbitral award in June 2010, at the earliest. Metso will pay
the redemption price within a month after the arbitral award has become legally
binding, which is estimated to take place in August 2010 the earliest.

Upon application by Tamfelt, NASDAQ OMX Helsinki Ltd (the Helsinki Stock
Exchange) has decided that the shares in Tamfelt will be delisted from the
official list of the Helsinki Stock Exchange when title to all shares in Tamfelt
has been transferred to Metso. The trading and the listing of the Tamfelt shares
on the Helsinki Stock Exchange will therefore cease in accordance with a
separate release to be published by the Helsinki Stock Exchange.
