Milan, February 5, 2003 A feasibility study for the construction of a new Algeria-Sardinia-Italy gas pipeline got under way following the establishment of GALSI S.p.A., which was incorporated in Milan on January 29, 2003 by the stockholders Edison Gas S.p.A., Enelpower S.p.A. (Enels engineering arm), Eos Energia S.p.A. (an energy trader controlled by Hera S.p.A.), Sonatrach S.p.A. (Algerias national hydrocarbons company) and Wintershall AG (a German energy company that is part of the BASF Group). Renato Pozzi, Technical Manager of Edison Gas, was named GALSIs Chairman. The study will assess the feasibility of building a new gas pipeline to bring Algerian gas to Italy. This project, which will link Algeria and the Italian mainland via the Island of Sardinia, has great strategic value for the development of an Italian natural gas distribution system. Moreover, the pipeline will optimize the flow of gas supplies, support the growth of the European energy market and make natural gas accessible to users in Sardinia. The first meeting of GALSIs Board of Directors is tentatively scheduled for the middle of February. Items on the Agenda include the appointment of a Chief Executive Officer, the preparation of an organizational chart and the drafting of a business plan. GALSI, which is based in Milan at Edisons Foro Buonaparte headquarters, is owned 40% by Sonatrach S.p.A., 20% by Edison Gas S.p.A., 15% each by Enelpower S.p.A. and Wintershall AG, and 10% by Eos Energia S.p.A.
