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

CEZ is prepared to submit to the government a bid for the purchase of a 55%
interest in Severoceske doly that would increase its 37% interest in the company

CEZ welcomes the government's decision because the opportunity to obtain a
majority interest in Severoceske doly wherein CEZ already owns more than 37% is
of significance for CEZ's future.

"This is a possibility to gain security with regard to future operation of new
or completely renovated powerplants into which CEZ will invest over CZK 100
billion in the years to come. The actual ownership provides us with greater
security in terms of a reliable operation of the powerplants in the future,"
said Martin Roman, CEZ's Chairman of the Board of Directors and CEO.

CEZ and Severoceske doly are interdependent to a great degree - 80% of SD's
production is for CEZ, covering 60% of CEZ's requirements, and the acquisition
of SD by CEZ this is the sole logical solution. Competitors are organized along
the same lines.

Unlike black coal, brown coal cannot be exported and freely traded (it is used
only in the Czech Republic and the former East Germany, and because of its low
calorific value in proportion to volume, long-distance transport is
uneconomical); on the other hand, powerplants are designed and tailored to the
burning of coal with specific properties and that cannot be easily changed.
Ownership structure notwithstanding, there is no market environment to speak of.
