Moscow. 27 July 2007. The Audit Committee of RAO "UES of Russia" reviewed and noted the information regarding changes in the interests in the Company held by members of the RAO UES management bodies. These changes are connected with the acquisition of the Company's shares by a number of members of the Management Board under the stock option agreement.

As previously reported, in June 2004, pursuant to the resolution of the Board of Directors of RAO "UES of Russia" on the Terms and Conditions for the Conclusion and Implementation of Stock Purchase Plans by Senior Executives and Employees of RAO "UES of Russia", the Management Board members signed stock option agreements to purchase part of the Company's shares. The exercise date for the stock option agreements was 25 June 2007, based on the assumption that the electricity reform will have been competed by that time. (As is known, the deadline for the completion of the reform was postponed to mid-2008.)

In May 2007, the Management Board members took a decision not to sell the RAO UES shares acquired under the stock option agreement until the reorganization is completed, except for a limited number of shares, the proceeds from which will be used only to pay tax, repay loans and other liabilities under the stock option agreements. The Management Board members resolved to convert the remaining shares into the shares of the companies of the intended (post-reform) sector structure spun-off from the Company on the same terms as were set for all minority shareholders. The Board members will be able to decide on further disposal of the acquired shares only after 1 July 2008.
