NEW YORK, August 10, 2007 — The Bank of New York Mellon, a global leader in asset management and securities servicing, has been selected by TomCo Energy plc as the depositary bank for its American depositary receipt (ADR) program. Each TomCo Energy ADR represents 200 ordinary shares. The ADRs trade on the over-the-counter market under the symbol "TMCGY," and the ordinary shares are listed on the London Stock Exchange under the symbol "TOM."

TomCo Energy, headquartered in the Isle of Man and founded in 1987, is an AIM-listed company which continues to actively develop a conventional oil production profile in the southwestern United States. The company also owns leases on approximately 3,000 acres of shale oil holdings in Utah, estimated by SRK (an independent firm of mining consultants) to contain approximately 230 million barrels of oil.

Howard Crosby, chief executive officer of TomCo Energy, said: "The introduction of TomCo ADRs will enable potential North American investors easier access to the company's shares in their own time zone and currency. The wider US awareness of TomCo Energy afforded by the introduction of the US dollar-denominated ADRs should greatly assist the company with its ongoing acquisition strategy and evaluation of further oil and gas opportunities."

Christopher Sturdy, executive vice president and head of The Bank of New York Mellon's Depositary Receipt Division, said, "We look forward to working with TomCo Energy as it further targets U.S. investors via a Level I ADR program. As the depositary for 71% of all sponsored DR programs from the UK, we have extensive experience with UK issuers and will support TomCo Energy with personalized investor outreach initiatives to help broaden their shareholder base."
