As of April 25, 2007, the trade in ordinary shares in Generation Company Four of the Wholesale Power Market (OGK-4) at MICEX (code: OGKD) and RTS Stock Exchange (code: OGKDG) will be suspended. The trade in OGK-4 shares on the RTS Classical Market has been suspended since April 20, 2007. The suspension of trading in OGK-4 shares is due to the conversion of shares of the first issue (par value of 1 ordinary share: 1 ruble) into shares of the second issue with a lower par value (par value of 1 share: 0.4 ruble) scheduled by for April 25. In this connection, shares of the first issue with a par value of 1 ruble will be simultaneously redeemed (canceled).

On April 19, 2007, the Federal Financial Markets Service (FFMS) decided on the state registration of the OGK-4 Decision on Securities Issue and the OGK-4 Prospectus for shares to be placed by conversion. The state registration number of the issue is 1-02-65104-D. OGK-4 shares of the second issue are expected to start being traded at the stock exchanges in May 2007, after the state registration of the Report on the Issue Results. According to the Standard for Securities Issues approved by the FFMS Resolution, the State Registration of the Report on the Issue Results shall be performed by the Regulator not later than 14 days from the date of receipt of relevant documents from the Issuer.

According to an earlier statement made by Deputy Director General for OGK-4 Corporate Policy Sergey Zhizhoma, the measures for the decrease of the OGK-4 authorized capital are of a technical nature. "For its part, OGK-4 will apply its best efforts, in terms of preparation of relevant documents and adherence to the requirements of RTS and MICEX, to have the trade in OGK-4 shares resumed as soon as possible," emphasized Mr. Zhizhoma.

The decision to reduce the OGK-4 authorized capital by means of decreasing the par value of the placed shares was made at the March 1, 2007, Extraordinary General Meeting of the Company. The authorized capital of the Company will be reduced from 49,130,625,974 rubles to 19,652,250,389.6 rubles, with a par value of one registered ordinary share in OGK-4 to be decreased from 1 ruble to 0.4 ruble. The decrease in the OGK-4 authorized capital is in accordance with the Federal Law "On Joint-Stock Companies" to align the net asset value with the Company's authorized capital.
