Armstrong World Industries, NPM Capital Discuss Acquisition Agreement

Armstrong World Industries Inc., a
Lancaster, Pa.-based international flooring manufacturer, is currently in discussions with NPM
Capital NV, Amsterdam, to enter into an agreement whereby NPM Capital will purchase Tapijtfabriek
H. Desseaux NV and its subsidiaries — the principal operating companies within Armstrong’s European
Textile and Sports Flooring business.

The Netherlands-based Desseaux — which recorded sales of $262 million in 2005 — and its
subsidiaries produce broadloom carpet and carpet tiles for residential and commercial use in
Europe, and synthetic turf for sports applications in the United States and Europe.

Armstrong will retain ownership of Desseaux businesses related to linoleum-based indoor
sports flooring and automotive carpeting.
