Relevant persons have been identified to be directors, effective auditors of Eni S.p.A., the Representative of the Court of Accounts delegated to control Eni, the managers directly reporting to the Chairman and the Chief Executive Officer of Eni S.p.A. and the managers directly reporting to the aforementioned first line of managers. According to the Code, the market has to be informed at the end of each calendar quarter about the operations carried out by relevant persons if their amount (in each calendar quarter) exceeds euro 35,000 (the limit set by the Rules of the Italian Stock Exchange is euro 50,000) while the market has to be informed without delay of transactions if their amount exceeds 175,000 (the limit set by the Rules of the Italian Exchange is euro 250,000).

PRESS RELEASE

Eni: acquired a 50% stake in Union Fenosa Gas

“The investment in Union Fenosa Gas represents a milestone in the growth strategy in the gas
sector at European and International level”, declared Vittorio Mincato, CEO of Eni

Eni has entered into an agreement with Unión Fenosa, S.A. for the acquisition of 50% of Unión Fenosa Gas. The transaction will be implemented through a share capital increase of Unión Fenosa Gas underwritten by Eni for a total consideration of € 440 million.

The asset value attributed to Unión Fenosa Gas amounts to € 930 million.

Eni will contribute to the Joint Venture its large experience as international player in the natural gas business, as the largest oil and gas producer in Egypt and largest gas marketer in Europe. In the Iberian Peninsula Eni already operates with gas sales in Spain, expected to reach 1.7 bcm per year by 2004, and it is the strategic partner of Galpenergia with its 33.4% participation. The strategic partnership with Galpenergia, to which will be offered the possibility to participate to common projects, will allow the development of potential synergies between Unión Fenosa Gas and Galpenergia.

Unión Fenosa Gas holds all the gas interests of Unión Fenosa and will operate in the whole gas chain from natural gas acquisition at source to the sale of gas to power stations and other end-customers. Unión Fenosa Gas will benefit from the upcoming liberalisation of the Spanish gas market from 2003 and from the growth of natural gas consumption which is expected to increase by 10% average per year up to 42 bcm by 2010.

Unión Fenosa Gas has a 25-year contract, with an option for a 25 year extension, involving a minimum of 4 bcm per year with the Egyptian Natural Gas Holding Company (EGAS). The company is also building a liquefaction plant with a capacity of more than 7 bcm per year in Damietta, on the Egyptian coast. In addition, in May 2002 Unión Fenosa Gas signed an agreement with the Government of the Sultanate of Oman to develop a joint venture in the gas sector, including the participation in a new liquefaction plant in Oman, which is expected to start operations from 2006. From then onwards, a long-term contract will guarantee further 2.2 bcm per year for a 20-year period.

Moreover, Unión Fenosa Gas has two LNG Time-Charters contracted for 25 years and will have consistent regasification capacity. Also, Unión Fenosa Gas currently holds a 21% stake in Reganosa and a 50% stake in Sagunto regasification plants, which will start operations in 2005.

Unión Fenosa Gas will serve the Spanish market with an expected sales share of 15% and will also be active in other international markets.

In particular, Unión Fenosa Gas will sell 2.5 bcm of gas per year to Union Fenosa CCGT plants.

“The investment in Union Fenosa Gas represents for Eni a milestone of its growth strategy in the gas sector at European and International level, strengthening our position in the LNG market”, declared Vittorio Mincato, CEO of Eni. The Damietta liquefaction plant will play a fundamental role in contributing to a faster monetisation of Eni gas reserves in Egypt. Moreover the agreement

strengthens Eni’s position in Spain and is complementary with our existing strategic alliance with Galpenergia”.

“Eni has come out to be the best partner to develop our gas strategy in the Iberian and International market — said Honorato López Isla, CEO of Unione Fenosa — for its strategic vision, sound financial position and ample background and experience in the gas industry. This transaction is part of Unión Fenosa’s current strategy to focus on developing its core business in the Iberian market, taking advantage from the ongoing liberalisation process and the power and gas convergence as a central point for future growth and shareholder’s value creation”.

The transaction is subject to European Commission approval according to Merger Control Regulation (ECMR).

Eni operates in the oil and natural gas business, the electricity generation sector, the petrochemicals and the service and engineering sectors, where it has achieved leading positions at international level.
