                  TEPLARNA DVUR KRALOVE TO REMAIN IN CEZ GROUP

At its meeting held yesterday, the Board of Directors of CEZ resolved to cancel
a tender for the sale of Teplarna Dvur Kralove and on the termination of its
sale. This is due to further negotiations with VCT of Pardubice and current
market developments.

The General Meeting of CEZ, a. s., which is scheduled for May 23, will be
informed in detail on the grounds for the withdrawal of the offer for the sale
of a portion of an enterprise in the form of Teplarna Dvur Kralove within the
relevant item on its agenda.

CEZ intends to expand the heating power business and search for other
opportunities in this field.
