Siegfried Outsources Support Functions

Zofingen, July 30, 2010 -- Siegfried Holding AG (SIX: SFZN) signed a cooperation agreement with two companies concerning the supply of support functions. In the future, Bilfinger Berger Industrial Ser- vices Swiss AG will provide maintenance, part of the engineering and security services and run the Siegfried HAZMAT Training Center. All issues concerning utility supply and waste disposal will be handled by IHKW Industrieheizkraftwerk Zofingen AG, a subsidiary of GWE Gesellschaft für wirtschaftliche Energieversorgung mbH located in Freiburg, Germany.

The agreement with Bilfinger Berger commences on August 1, 2010 and that with IHKW on September 1, 2010. In total, 56 Siegfried members of staff will change employer. Siegfried negotiated with the new employers two years’ job security and protection of vested rights for a period of three years for its former employees.

CEO Dr. Rudolf Hanko: “Both Siegfried and its customers will continue to benefit from first- class service, however, at lower cost, due to the commitment of two professional providers in the field of maintenance and utility. The agreement has brought about a win-win situation for Siegfried, its members of staff changing employer, and the new partners.”
