On May 31, 2013, the Board of Directors of Metso Corporation approved a demerger
plan, which was registered with the Finnish Trade Register on June 6, 2013.
Pursuant to the demerger plan, Metso Corporation will demerge in a partial
demerger to the effect that all such assets, debts and liabilities of Metso
Corporation that relate to Metso Corporation's Pulp, Paper and Power businesses
(the "PPP Business") will transfer, without liquidation, to a company to be
incorporated in the demerger (such company, "Valmet Corporation") in the manner
set forth in more detail in the demerger plan.

The purpose of the demerger is to execute the separation of Metso Corporation's
businesses to the effect that the PPP Business is separated to Valmet
Corporation and Metso Corporation's other businesses, including, among others,
the Mining and Construction as well as the Automation businesses, will remain
with Metso Corporation.

The Board of Directors of Metso Corporation proposes that the General Meeting
approves the demerger plan and decides on the partial demerger of Metso
Corporation in accordance with the demerger plan. Valmet Corporation's Articles
of Association, which are attached as an appendix to the demerger plan, will be
approved as a part of the demerger.

Pursuant to the demerger plan, a decrease in the share capital of Metso
Corporation is proposed in connection with the demerger by an amount equaling
Valmet Corporation's share capital, or EUR 100,000,000, to EUR 140,982,843.80.
The amount by which the share capital of Metso Corporation is decreased will be
used to distribute funds to Valmet Corporation.
