Prague Stock Exchange as required by its rules and regulations:

            CEZ CONTINUES IN TENDER FOR MACEDONIAN DISTRIBUTOR AD ESM

Today, the energy corporation, CEZ, filed a binding offer for the majority share
in AD ESM. The tender for this 90% stake in a Macedonian electricity distributor
was announced towards the end of last year. CEZ registered for the tender in
December 2005, and was short-listed along with three other bidders.

"By filing this bid, we underscore our interest in the Macedonian energy
industry. It is to the advantage of CEZ that it only recently underwent [a
similar kind of] restructuring of the energy market in the Czech Republic, and
has successfully assumed control of distribution companies in Bulgaria and
Romania. Today, CEZ is is one of the most profitable and least indebted European
energy companies. We would love to carry over our experience into Macedonia, as
we proceed on the way toward our goal to become number one on the electricity
markets in Central and Southeastern Europe," said Martin Roman, chairman of the
board and CEO of CEZ.

AD ESM supplies 721,000 final customers (consumers) and sells 4.4 TWh of
electricity per year. Aside from its distribution activities, ESM also owns 11
small hydropower stations with a total installed capacity of 38 MW. The annual
power production in Macedonia is about 6.2 TWh of electricity, of which more
than 75% is generated by heat power plants; the remaining 1.5 TWh is produced by
hydropower plants. Imports make for almost 16% of the annual electricity
consumption; the total consumption in 2004 was approximately 7.4 TWh and the
consumption estimate for 2005 is 7.7 TWh.
