The following information was filed by CEZ, a. s. in Czech language with the
Prague Stock Exchange as required by its rules and regulations:

      The energy corporation CEZ files another offer for Zespol Elektrowni
                             Dolna Odra S.A. today

CEZ continues in the privatization tender by filing another offer for the Polish
power generation company Dolna Odra. CEZ filed its first offer for a share of
min. 10% at the end of April this year; based upon that offer, it was
shortlisted for the second round in which six prospect buyers participate. Based
upon preliminary offers, the Polish government is to choose a selected group of
bidders and will later decide also on the specific size of the privatized share.

"The energy corporation CEZ has previously been successful in making
acquisitions in southeast Europe, where we own distribution companies in
Bulgaria and Romania already. Pursuing our goal to become the leader in the
electricity market of the CEE region, we find that Poland is the strategic
market in Central Europe for us. The immediate proximity with Poland means that
both energy companies know each other well, which is key for a possible future
partnership," says Martin Roman, Chairman of the Board and CEO of CEZ. Dolna
Odra is the fifth-largest electricity producer in Poland. Its complex consists
of three power plants (Dolna Odra [Lower Oder], Pomorany [Pomerania], and Stetin
[Stettin]); the total installed load is 1 960 MW. In the course of its expansion
activities, CEZ has so far smoothly taken over three Bulgarian-based
distributors and at the beginning of April signed an agreement on the
privatization of the company Oltenia in Romania. By way of these acquisitions,
CEZ almost doubled the number of its final customers to 6.6 million and thus
soared to the eighth rank among Europe's energy companies in terms of this
criterion.
