Paris, September, 22^rd 2008 – GDF SUEZ has acquired from Hellenic Petroleum S.A. (Hellenic), the Greek integrated energy group, a 20% participating interest in an exploration and production license in Libya, thus partnering alongside with Woodside and Repsol. The transaction has been approved by the National Oil Corporation and remains to be ratified by the Libyan Parliament, the Great Socialist People’s Libyan Arab Jamahiriya.

Operated by Woodside, the oil and gas license allows for the exploration of 5 onshore blocks located in the Sirte basin and one block in the Murzuq basin. These six blocks extend to a total surface area of 20,129 km². Under the terms of the exploration and production sharing agreement, signed by the consortium and the National Oil Corporation (NOC), an option exists to negotiate the terms of the appraisal and development of an additional block, also situated in the Murzuq basin. This license contains announced oil and gas discovery xxxxx and offers significant exploration potential.

GDF SUEZ is already a buyer of natural gas from Libya, having signed a long-term agreement with the energy provider ENI in 2001 to purchase 2 billion cu.m a year. The group has for a number of years wished to increase its involvement in the gas industry in this country, one of Europe’s natural suppliers. Since 2004 the Group is sanctioned by Libyan authorities to participate in exploration and production activities. The acquisition of this license enables GDF SUEZ to become an upstream player in Libya.

The Group will be in a position to increase its reserves from 670 to the medium term target of 1,500 million barrels of oil equivalent. By diversifying its portfolio, GDF SUEZ is strengthening its position as a major gas supplier for its customers and its electricity generation fleet.” indicated Xxxx-Xxxxx Xxxxxx, Executive Vice President of GDF SUEZ in charge of Global Gas & LNG.
