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

Energy corporation CEZ places bid for Zespol Elektrowni Dolna Odra S.A.

Today, the energy corporation CEZ has submitted a preliminary offer for the
privatized Polish-based electricity company Dolna Odra. CEZ thus enters into the
privatization tender for a minimum 10% stake in this company.

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. The complex
consists of a power plant (located in the Lower Oder valley) and two heat plants
(Pomerania and Szczecin), and its total installed capacity reaches 1,950 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.
