The Bank is now depositary for 14 companies created as part of the restructuring of Russia's electricity sector

NEW YORK, August 26, 2008 — The Bank of New York Mellon (NYSE: BK), the global leader in asset management and securities servicing, has been selected as the depositary bank for the Regulation S and 144A global depositary receipt programs of eleven new companies spun off from RAO Unified Energy Systems of Russia (RAO UES) in a broad restructuring and demonopolization of Russia's energy sector.

On June 30, 2008, as part of a restructuring plan that began to take effect in 2007, RAO UES of Russia ceased to exist and was reorganized into a number of private companies. In 2007, The Bank of New York Mellon was appointed as the depositary bank for the GDR programs of OGK-5 and TGK-5 and in June 2008 as the depositary bank for the GDR program of JSC Rushydro. As a result, the 11 new appointments in Phase II of the restructuring bring to 14 the number of RAO UES spin-off companies that have selected The Bank of New York Mellon as their depositary.

The 11 companies and their global depositary receipt (GDR) program ratios are noted in the chart below. Companies beginning with "TGK" are territorial generating companies and companies beginning with "OGK" are wholesale generating companies. None of the GDRs and ordinary shares have been registered under the U.S. Securities Act of 1933 and may not be offered or sold in the U.S. absent registration or an applicable exemption from the registration requirements.

"As the leading depositary bank, we have extensive experience with complex corporate reorganization DR transactions," said Michael Cole-Fontayn, chief executive officer of The Bank of New York Mellon's Depositary Receipt Division. "We are pleased to be working with these energy companies as they enter the public markets, and we look forward to helping them achieve their depositary receipt program goals."
