23 July 2003

Umicore USA Inc. has acquired certain assets of EaglePicher Technologies' germanium products business line, based in Quapaw, Oklahoma, for approximately USD 15 million in cash. These assets relate to the production of germanium-based products primarily used in infra-red optics and fibre optics applications. The transaction does not involve any of EaglePicher's assets that are involved in the production of germanium substrates.

This acquisition fits into the global, worldwide growth strategy of Umicore's Advanced Materials business.

The newly acquired business (formerly EaglePicher Electro-Optic Materials) is to be known as Umicore Optical Materials USA Inc. It will be integrated into Umicore's Electro-Optic Materials business unit and will provide this business with a valuable, US-based production and sales platform.
