of the coated kraft paperboard produced at Klabin's Monte Alegre paper
mill located in Telemaco Borba, Parana, Brazil. The agreement will go
into effect January 1, 2008.

gives MeadWestvaco the opportunity to expand our portfolio of
high-quality packaging substrates and extend our industry leading
Coated Natural Kraft(R) line," says Charles Johnson, vice president of
Global Businesses for MeadWestvaco's Packaging Resources Group. "The
