                  CEZ Places Binding Bid for Majority Share in
                 Polish Electricity Companies ELCHO and Skawina

Today, the energy corporation, CEZ, delivered to the U.S. energy corporation,
PSEG Global L.L.C., their binding offer for the purchase of majority shares in
the Polish power supply companies, Elektrocieplownia Chorzow Elcho Sp. z o.o.,
and Elektrownia Skawina S.A.

"By submitting this binding offer of ours, we underscore the serious interest of
the CEZ group in the Polish energy market which, in light of our vision to
become number one on the electricity market in central and southeastern Europe,
is the priority market in the CEE region," says Martin Roman, Chairman of the
Board and CEO of CEZ.

The power supply companies, Skawina and Elcho, are located in southern Poland
and both produce combined heat and power. The shares in these companies sold by
PSEG group are 74.82% in Skawina and 88.82% in Elcho.

The installed capacity of the hard coal power plant of Skawina is 590 MWe; it
produces roughly 3 TWh electricity each year. As a CHP power plant, the plant
supplies the town of Skawina and the western part of Krakow with heat and hot
water. The generated electricity is delivered to local distribution companies.

Elcho is 8 km to the northwest of Katowice and produces co-generated heat and
power by burning hard coal in two modern blocks with a total installed capacity
of 220 MWe. The client for 100% of the electricity produced by this plant is the
Polish transmission network operator, PSE; the heat generated by the plant is
delivered to Katowice and its surroundings.
