The Glass Sector has benefited in the first quarter from a dynamic economic
environment especially in Europe. In the United States, where the market remains
buoyant, growth is continuing.

The High Performance Materials Sector has evolved in its end-user markets in a
favourable climate for the first months of the year, and its American activities
have made a significant recovery in particular in the semi-conductors market.

The Housing Sector has shown strong levels of activity across all its business
areas. In Europe, the end-user markets for the Group's product are particularly
buoyant.
