In its meeting on January 26, 2006, the supervisory board of CEZ discussed the
resignation of its chairman, Mr. Jiri Havel, dated December 20, 2006. His
membership on the supervisory board has thus ended. Mr. Zdenek Hruby, previously
vice-chairman of the supervisory board, was elected as the new chairman. For the
period until the general meeting of CEZ convenes, Mr. Zdenek Trojan has been
co-opted as new member of the supervisory board. Mr. Jiri Bis, already a
supervisory board member, has newly been appointed vice-chairman.

Mr. Zdenek Trojan (born in 1936) graduated from the Faculty of Engineering at
the Czech Technical College CVUT (1959), became a candidate of the Academy of
Sciences (CSc.) in 1974, and habilitated as lecturer ("doc.") in 1991. Since
1962, he has been working at the Faculty of Engineering at the CVUT (newly the
Institute for Processing Technology). During 2004 - 2005, he was advisor to the
minister for regional development; he is currently advisor to the prime
minister.
Among others, Mr. Trojan was member of the Chamber of Deputies of the
Czech Parliament (1992 - 1996) and member of the Municipal Assembly of the
