Rome, May 20, 2002 The Chief Executive of Enel SpA, Franco Tatò, and the Chairman of the ACI (Italian Automobile Club), Franco Lucchesi, have signed a memorandum of understanding for the definition and development of joint offers of products and services for their clients and members. The Memorandum includes, among other things, the evaluation of synergies in their commercial channels. In this sense, the network of Enel-si store franchises, which will reach 2,500 points of sale by 2004, and the 1,500 ACI locations are particularly important. A mixed working group will verify the possibility and terms for the installation at the ACI locations of So.l.e products, such as videocommunication systems, illumination and mobile telephony towers (Webtower), eco-recharge towers for electric vehicles and environmental monitoring systems. The main groups involved are Enel Distribuzione (the Enel group company that offers energy distribution services nationwide), Enel.si (the Enel group company that offers services in the areas of electrical systems, security, comfort and energy savings) So.l.e (the Enel group company for public lighting and related innovative services and products) and the companies of the ACI group. The memorandum will be valid for six months with the possibility of extension.
