South Africa or the United States.

Ahlstrom, a global high performance fiber-based materials company, has today
completed the first phase of the combination of its Label and Processing
business in Europe and Munksjö AB (LP Europe Completion). The combination
creates a new global leader in high-quality specialty papers.

The second phase of the transaction, the demerger of Coated Specialties in

"The rationale for this transaction remains sound: Ahlstrom can now focus on
businesses in which we see the most attractive value-add and growth
opportunities. On the other hand, the Label and Processing business can be
further developed as part of a leading specialty paper company," says Jan Lång,
President & CEO, Ahlstrom.

Insurance Company. Ahlstrom's share of the issue amounted to approximately EUR
78.5 million entitling to 9,081,171 new shares in Munksjö Oyj.

Further, Munksjö Oyj has today, as part of the LP Europe Completion, resolved to

Ahlstrom shareholders' ownership

0.25 new shares in Munksjö Oyj for each share owned in Ahlstrom Corporation
(i.e. the exchange ratio is 4:1). In case the number of shares received by a
shareholder of the company as LP Europe demerger consideration would be a
fractional number, the fractions shall be rounded down to the nearest whole
number. No LP Europe demerger consideration will be paid on the basis of own
shares held by Ahlstrom Corporation.

The new Munksjö shares carry a right to dividend and other shareholder rights as
from their registration with the Finnish Trade Register on May 27, 2013. The
process does not require any action from the current Ahlstrom shareholders. The
trading with Munksjö's shares is expected to commence on June 7, 2013.

on July 4, 2013, to approve the demerger plan for Coated Specialties, since the
current authorization for the demerger expires on May 27, 2013.
