fit with Munktell and Ahlstrom, and the transaction allows us to strengthen our
product portfolio in advanced filtration materials. This move is a prime example
of our focus on new type of high performance materials business with attractive
future growth potential."

 "When we combine Munktell's strong position in the European advanced filtration
market with our solid presence in North America, we will gain access to new

and laboratory filtration are lucrative growth areas for us," added Tommi
Björnman, Executive Vice President, Filtration.

Munktell is based in Falun, Sweden and it has production sites in Germany and
Sweden, a joint venture in France, as well as a sales office in the U.S. The
