Eni reported a net income for year 2002 amounting to euro 4,593 million, an 11% decrease over 2001 in comparable terms. Capital expenditure (euro 8 billion) increased by euro 1.5 billion over 2001 (up 22%) and concerned for 93% the Exploration & Production, Gas & Power and Refining & Marketing divisions. Self-help measures generated savings for euro 500 million bringing total savings achieved in the 1999-2002 period to euro 1.7 billion

With the merger of Snam and AgipPetroli the transformation of Eni’s organizational structure, started in 1997 with the merger of Agip, was completed. Now Eni is an operating company with direct governance of its three main businesses: Exploration & Production, Gas & Power and Refining & Marketing

In 2002 daily hydrocarbon production reached the record level of 1,472,000 boe with a 7.5% increase over 2001, due to increases in consolidated areas and start-ups of relevant fields. In the fourth quarter of 2002 daily production was 1,527,000 boe reaching the 1.5 million boe target set for 2003 one year in advance. Eni intends to maintain a strong production growth in the near future leveraging on internal development and targeting over 1.8 million boe/day in 2006 (an yearly average increase of approximately 6%). Eni’s proved reserved reached over 7 billion boe

The purchase of the Norwegian company Fortum Petroleum completed in March 2003, with a daily production of 39,000 boe in 2002 and proved and probable reserves of 202 million boe, is part of Eni’s strategy of development of upstream activities through a strengthening in key areas and an increase in interests in assets partially held in order to create operating synergies. This purchase allows an approximately 40% increase in Eni’s hydrocarbon production in Norway in 2003

The importance of the Kashagan oil field discovery (Eni is single operator with a 16.67% interest) in the Kazakh offshore of the Caspian Sea was confirmed by the appraisal activities performed and underway in the area. The field’s recoverable reserves, calculated according to the most recent estimates in 7-9 billion barrels, reach 13 billion by employing gas reinjection techniques and make Kashagan the most relevant oil the discovery in the past thirty years

Within its strategy of international expansion in natural gas activities, in joint venture with the German electricity company EnBW, Eni purchased GVS, one of the major regional operators in natural gas distribution in Germany with sales of approximately 7 billion cubic meters of gas per year; with this operation Eni enters a large natural gas market. Eni also defined the purchase of a 50% interest in Spanish natural gas company Unión Fenosa Gas, which is developing its activity in natural gas in Spain and internationally. With this transaction Eni strengthens its presence in the Spanish natural gas market which shows significant growth prospects. These two deals will allow Eni to strenghten its European leadership

The public purchase offering on approximately 56% of the share capital of Eni’s subsidiary Italgas at the unit price of euro 13 per share is part of Eni’s strategy of rationalization and development of its natural gas activities also at international level. The public offering was successfully closed on January 27, 2003; Eni now owns 98.285% of Italgas share capital and is squeezing out the remaining shares outstanding

Within its program of development of electricity generation capacity at Eni’s industrial sites, work started for the construction of a new combined cycle power plant at Ferrera Erbognone (Pavia) with a capacity of 1,030 megawatts and for the upgrade of the Ravenna power plant with the installation of two new combined cycle groups for a total capacity of 780 megawatts

Eni continued its program for repositioning its downstream oil activities: in 2002 Eni completed the new set up of the Priolo refining pole, with this operation Eni targets a 7.5 million tonnes reduction in its own processing by 2006. Further Eni defined agreements, presently in the finalization phase, for the purchase of 313 service stations in selected areas in Europe (Spain, Germany, France), where it intends to expand its presence by leveraging on operating synergies and on its well known brand name, and for the sale of 330 service stations in Italy (adding up to the 246 service stations sold in 2002).

Saipem’s purchase of Bouygues Offshore creates a new world leader in oilfield services. The combination of Saipem’s recognised construction capabilities supported by technologically advanced vessels, and Bouygues Offshore’s world-class engineering capabilities allows to strengthen Saipem’s competitive position in the segment of large EPIC projects for the development of hydrocarbon offshore fields.

Letter to our Shareholders

To our shareholders, in 2002 Eni confirmed its ability to achieve positive results in a context of serious slowdown of world economy charachterized by uncertainty after the tragic events of September 11, 2001. The early signs of the Iraqi crisis and the repercussions of that crisis on international markets dampened the modest signs of recovery registered in the second half of 2002. Eni’s net income amounted to euro 4.6 billion (down 11% over 2001 in comparable terms). Return on average capital employed (ROACE) amounted to 13.7%; the debt to equity ratio increased slightly (0.39 as compared to 0.35 in 2001) despite significant capital expenditures and financial investments (euro 9.4 billion).

Vittorio Mincato, Managing Director

##### Table of Contents

Daily hydrocarbon production reached the record level of 1,472,000 boe, the growth in natural gas sales in Europe was significant with a 5.1 billion cubic meter increase in volumes sold; in refining Eni further increased its competitive position having reduced by 2.3 million tonnes its intake in low-complexity refineries located far from consumption markets; in refined products distribution Eni continues its upgrading process in Italy which led to a 4% growth in average throughput of service stations.

These positive aspects are confirmed in light of the price scenario and the behaviour of the competition in 2002.

As for the first aspect, 2002 was marked by a series of negative external factors such as a decline in refining margins (Brent was down 59.4%), the 5.6% appreciation of the euro over the dollar and a decline in natural gas prices while average international oil prices increased by 2.1%, an increase insufficient to offset the negative factors mentioned above. All this notwithstanding, Eni’s ability to cope with a negative scenario is evidenced by the comparison of Eni’s results with

Two indicators appear especially important: Eni’s net income, despite its 11% decline in comparable terms over 2001, appears far less negative than the average 23% decline of major oil companies. At the same time, Eni maintained its commitment to increasing hydrocarbon production in a phase in which expansion and the delivery of satisfactory profitability is a relevant critical factor for most industrial activities.

The proof of Eni’s industrial and financial stability provided by these results allows us to propose to the Shareholders’ Meeting a dividend amounting to euro 0.75, the same amount paid last year, with a 62% pay-out.

2002 results

In 2002 Eni continued with great resolve on the lines of production growth and international expansion in core business areas. Our effort in implementing strategic guidelines, a strict financial discipline in our investment choices and the constant monitoring of efficiency improvements allowed to achieve the goals set, strengthening Eni’s competitive positioning.

In the Exploration & Production segment, daily hydrocarbon production reached, as already said, the record level of 1,472,000 boe, with a 7.5% increase over 2001,

despite production cuts decided by OPEC and Eni’s portfolio rationalization actions. Reserve replacement ratio was 119% and proved reserve life index is over 13 years.

In the Gas & Power segment, Eni continued to manage in a proactive way the effects of the liberalization of the Italian gas market. Sales of natural gas in primary distribution amounted to 60.8 billion cubic meters, with a 1.2 billion decline over 2001 resulting from a decline of volumes sold in Italy (down 6.3 billion cubic meters) also due to weather conditions, and an increase in sales in Europe (up 5.1 billion cubic meters).

Within its strategy of international expansion in natural gas activities, in a 50/50 joint venture with the German electric company EnBW, Eni acquired GVS, one of the main regional distributors of natural gas in Germany, with sales of approximately 7 billion cubic meters/year and reached an agreement for the purchase of a 50% interest in the Spanish company Union Fenosa Gas, strengthening its position on the Spanish natural gas market, in particular in the area of liquefied natural gas.

The public purchase offering on 56% of Italgas shares, successfully closed on January 27, 2003 is part of Eni’s integration of commercial and development policies also at international level in natural gas.

In power generation, work started for the construction of the Ferrera Erbognone power station and for the upgrade of the Ravenna power station to a total capacity of 1.8 gigawatt. This proves Eni’s ability to develop new power generation projects in a shorter time than its competitors, seizing the opportunities provided by the development of the electricity market.

In the Refining & Marketing segment, Eni continued its process of upgrading its refined product distribution network in Italy and expanding its network outside Italy. To this end, Eni expanded its best equipped service station network in Italy by building and purchasing about 150 owned and leased service stations with high throughput and non oil sales activities, while it sold or closed about 800 service stations no longer meeting the quality and efficiency standards that Eni intends to achieve. In retail markets, Eni sold 14.4 billion liters of refined products (0.7 billion liters less than in 2001). In late 2002 Eni launched BluDiesel, a new virtually sulphur free diesel fuel which anticipates environmental regulations and ensures better engine performance. Service stations selling this new product were about 1,500 at year end with average sales amounting to 20-25% of total gasoil sales and in some instances peaking at 50%.

In retail markets in the rest of Europe Eni sold about 3.3 billion liters of refined products, with a 4% increase over 2001, due to the purchase of about 100 service stations in France and central-eastern Europe. Agreements for the purchase of another 313 service stations in selected European areas (Spain, Germany and France) are nearing finalization. In these areas Eni intends to develop its presence by leveraging on operating synergies and on its well known brand name.

In refining Eni reached an agreement concerning the Priolo refining pole, in Sicily, targeting a reduction of 7.5 million tonnes of refining capacity (to be reached in 2006). This deal is consistent with the aim of reducing low conversion refining capacity, which is structurally in excess and therefore more vulnerable to market volatility.

In the Oilfield Services and Engineering segment, Saipem bought French company Bouygues Offshore and consolidated its position as world leader in services for the oil industry.

Along with these specific actions, Eni was engaged in development projects that will contribute to its long-term growth, such as:

– |  | the completion of the underwater Blue Stream gas pipeline (from Russia to Turkey through the Black Sea) which represents the world record in underwater pipelaying and is one of the most daring projects ever built in terms of technology, engineering and project management. The construction of this pipeline confirms Eni’s attention to developing know-how and skills for the design, construction and management of advanced projects in the energy field;
– |  | the delimitation of the Kashagan field in the Kazakh offshore of the Caspian Sea, performed under Eni’s responsibility (Eni is operator of the field) confirmed the field’s exceptional size and confirmed it is the greatest oil discovery of the past thirty years;
– |  | the development of the gas and condensates Wafa and Bahr Essalam fields in permit NC41 in Libya, with the awarding of the main contracts for the construction of hydrocarbon treatment plants, a production platform and related transmission infrastructure for a total of euro 4.2 billion (2.4 net to Eni). Yearly natural gas production is targeted at 10 billion cubic meters, of these 2 are going to be sold on Libyan markets and 8 in Italy. This project enhances the value of Eni’s hydrocarbon reserves and entails the control of a strategic source for meeting the future needs of the Italian energy market.

Objectives reached and the value of reliability

2002 has proved to be an important step for attaining the growth objectives Eni had set for itself in its 2000-2003 four-year plan. These were ambitious and difficult targets that were set at a time when many of the cultural and industrial certainties that had accompanied Eni’s history were starting to fade out, in particular:

– |  | Italy as the reference market, where Eni played an institutional role as supplier of oil and gas to the country;
– |  | a context whereby the supply, transmission and sale of natural gas activities were performed by Eni in a virtually monopolistic position while rendering Italy an important service.

All this notwithstanding, in 2002 Eni had already reached and even stepped beyond many of the targets set for 2003:

– |  | in the Exploration & Production segment, the target of a 50% growth in production set for 2003 was reached already in the third quarter of 2002;
– |  | in the Gas & Power segment, the objective of sales in Europe reaching 10 billion cubic meters (from about 5 billion in 1998) was widely exceeded in 2002 and sales reached about 20 billion cubic meters;
– |  | in the Refining & Marketing segment, the capacity reduction target set in Italy from 41 million tonnes in 1998 to 36 million tonnes was achieved and exceeded at the end of 2002, making Eni’s refining system more responsive to the trends in consumption;
– |  | Eni’s focus on its core business, in terms of share of capital employed from 90% to over 95% was achieved in 2002;
– |  | the target of efficiency improvement in terms of cost cutting by euro one billion in the 1999-2003 period was widely exceeded by obtaining savings of about euro 1.7 billion already in 2002.

##### Table of Contents

The target of an increase in installed power generation capacity set to 5-7 gigawatts (from 2.4) is expected to be achieved in 2006, due to the length of time necessary to obtain authorizations for the construction of new power stations in Italy.

Growth was achieved through development on internal lines and by means of selected acquisitions of assets and companies under a strict industrial and financial discipline, paying great attention to the problem of the cultural management of acquired companies and the integration of human resources. This led to the success that accompanied Eni’s acquisitions.

The ability to meet with the commitments assumed with our shareholders, whatever the external situations, and the credibility gained in this process are two of the most important assets Eni has built upon in the past years.

The new organizational model

In 2002, Eni’s change strategy was deployed also through the completion of a new organization by means of the merger with Eni of Snam and AgipPetroli, whose businesses became industrial divisions of the parent company. After these mergers Eni has become an integrated energy company abandoning its traditional role of holding company and taking up a model of operating integration that already proved its efficacy in terms of speed of decisional processes.

The scenario: an ever increasing competition

In the next few years the scenario of the oil industry worldwide will be characterized by ever increasing competition.

The upstream sector will show as critical points: the reduction of investment opportunities accessible to private companies, the trend to an increase in technical costs resulting from the exploration efforts devoted to frontier areas, a progressive worsening of contract and tax conditions and the maturity of the oil areas located nearest to end markets.

In downstream gas, competition due to the entry of new operators attracted by the increase in natural gas demand and by the opening up of markets will determine relevant risks in terms of margins levels.

Refining in Europe shows significant profitability problems due to excess production capacity which requires closing down or streamlining of plants, especially those farther from markets or that cannot easily be adjusted to respond to changes in demand. In refined products distribution, margins are under pressure due to the entry into the competitive scenario of large retailers and to the changes in consumer expectations, with the request for a wide range of innovative services that are quite expensive for companies to provide.

Eni’s reaction: a qualified industrial growth

In order to successfully respond to these challenges Eni will continue the industrial expansion it pursued in the past three years by combining a qualified growth strategy and a strict economic and financial discipline with greater rigour in the management of its asset portfolio. The increase in the size of our company will allow: (i) to exploit relevant economies of scale, (ii) to improve operating efficiency and efficacy, (iii) to develop financial resources adequate for supporting highly innovative and deferred return comprehensive projects, in which Eni has a consolidated world leadership, (iv) to increase negotiation power and (v) to consolidate our ability to attract and keep skilled and experienced professionals.

To continue to grow after such an intense and fast growth process with a wider production basis is becoming more and more difficult in terms of industrial, economic and financial sustainability. Eni however sets as its foremost goal the ability to win this challenge linking growth, profitability and long-term sustainability.

In pursuing this qualified industrial growth Eni relies on a lean and flexible organization, capable of reacting to change, to customer requirements and to the quality and reliability of its products and services.

The growth model our company has chosen combines results, profits and innovation while paying constant attention to quality of life, standards of work, human rights and sustainable development. Eni’s commitment to this end takes the form of principles, policies and management behaviours that characterize our company wherever it operates, aiming at promoting a culture of sustainability and at gaining the trust of shareholders and in more general terms of all our stakeholders.

Strategic guidelines and actions

Just as in the past three-year period, also in its 2003-2006 four-year plan Eni set challenging but realistic goals, that can be monitored on a timely basis and following up the ones already attained.

In the Exploration & Production segment, growth translates into: (i) a 6% production growth rate to be achieved by leveraging only on internal growth and net of divestments; (ii) international expansion accompanied by greater focus on a few countries in order to increase critical mass and negotiating power and obtaining a better cost structure; (iii) improving operating performance in order to ensure long-term sustainability; (iv) focus on large high potential projects (gas in Libya, Kashagan, Kizomba) capable of supporting long-term growth.

In the Gas & Power segment, the growth of natural gas sales will be achieved essentially outside Italy, in particular in Europe, while in Italy Eni will maintain market shares at the levels set by the new laws by means of a better integration of commercial policies, the provision of excellent and reliable services and possibly alliances with local operators. The progressive internationalization of natural gas activities will be favored by developing the LNG segment.

Eni plans a gradual divestment of Snam Rete Gas, also foreseen by laws and regulations to be enacted soon, in order to concentrate resources in non regulated core business areas.

In power generation, generation capacity is targeted at 6.4 gigawatts in 2006. This will allow absorbing part of natural gas supplies available and achieving a better competitive position in terms of costs and efficiency of Eni power stations as compared to average power stations in Italy.

In the Refining & Marketing segment, the upgrade of the Italian network, with average throughput targeted at 2.8 million liter per service station, will be accompanied by an expansion of sales in Europe, targeted at sales of refined products on retail markets of about 4.9 billion liters.

In the Oilfield Services and Engineering segment, we will pursue leadership as global integrated contractors in large projects and will continue to improve efficiency, expertise and skills, in particular in offshore and natural gas enhancement activities.

13

##### Table of Contents

In the Petrochemical segment, we will pursue a further rationalization of the activities.

In a semi-mature industry such as the oil industry operating excellence and maximum efficiency are the indispensable levers of competitive advantage. Our cost cutting project, started in 1999, already allowed savings of euro 1.7 billion and new initiatives will lead to further savings of euro 1.7 billion by 2006.

From the standpoint of financial performance Eni’s strategy aims both at reaching the profitability goals set with the market and at generating relevant cash flows, entailing a reduction in net borrowings and debt to equity ratio, that will allow seizing further development opportunities also by external lines and at the same time supporting long-term growth.

Eni pays special attention to research and development, which it considers the engine for sustainable development and a lever of competitive advantage, as is evidenced by one of the highest ratios of R&D expenditure and turnover in the whole energy industry. In 2002 research structures were integrated by conferring to EniTecnologie the research units of AgipPetroli and Snamprogetti. This integration aims at enhancing the value of Eni’s wealth of knowledge and expertise, and orienting resources at large strategic projects. Eni selects research projects that lead to industrial solutions and application in areas critical for Eni’s development. The focus on research areas with long-term impact is pursued also through partnerships. The most relevant research projects underway are: optimization of high-sulphur hydrocarbon fields, upgrading of heavy hydrocarbons, conversion of liquids to natural gas, long distance transmission of natural gas in high pressure pipes, improvement of the environmental quality of products, development of renewable energy sources and production and use of hydrogen as a clean fuel.

From history to the future

In February 2003 Eni celebrated its first half century of life. Eni’s history was characterized from its inception by an almost impossible challenge, supported only by a frontier spirit and the resolve of a few men. Through difficult moments and exhilarating success and thanks to experience that story has become the genetic code of a company looking at the future, the common wealth of women and men that, renewing the commitment of the past with talent and dedication, continue to interpret the project of a boundless expansion by means of original strategies and development models through the integration with different cultures and the flexibility required to understand and adapt to the costumes and languages of other peoples. More than any other element, this way of being is what nourishes Eni’s strength in front of future challenges and allows us to aim at a tomorrow that we could not have imagined yesterday.

Exploration & Production

In 2002 daily hydrocarbon production reached the record level of 1,472,000 boe with a 7.5% increase over 2001, due to increases in consolidated areas and start-ups of relevant fields. In the fourth quarter of 2002 daily production was 1,527,000 boe reaching the 1.5 million boe target set for 2003 one year in advance. Eni intends to maintain a strong production growth in the near future leveraging on internal development and targeting over 1.8 million boe/day in 2006 (an yearly average increase of approximately 6%). Eni’s proved reserved reached over 7 billion boe.

In March 2003 Eni completed the purchase the Norwegian company Fortum Petroleum AS, with a daily production of 39,000 boe in 2002 and proved and probable reserves of 202 million boe. Eni’s investment, amounting to dollar 975 million, will allow an approximately 40% increase in Eni’s hydrocarbon production in Norway in 2003.

Eni is pursuing a program for the rationalization of its portfolio of assets aimed at concentrating its activities in areas with significant growth potential where Eni is operator: in 2002 Eni sold 16 interests in fields in the North Sea, Italy and Qatar, as well as exploration permits and other assets; Eni also acquired interests in operated or partially held assets in Kazakhstan, the United Kingdom, Norway and Australia.

The importance of the Kashagan oil field discovery (Eni is single operator with a 16.67% interest) in the Kazakh offshore of the Caspian Sea was confirmed by the appraisal activities performed and underway in the area. The field’s recoverable reserves, calculated according to the most recent estimates in 7-9 billion barrels, reach 13 billion by employing gas reinjection techniques and make Kashagan the most relevant discovery of the past thirty years.

In 2002 exploration activities were successful: worth mentioning are the discovery of the natural gas Tennin field in the Egyptian offshore facing the Nile delta (Eni is operator with a 50% interest) and in the Nigerian deep offshore the Bonga SW oil field (Eni’s interest 12.5%) and the new deep production levels of the ABO oil field (Eni is operator with a 50.19%. interest).

Streamlining measures and synergies obtained through the integration of purchased companies allowed for cost reductions amounting to euro 154 million.

Oil and natural gas reserves

Eni’s proved reserves of hydrocarbons at December 31, 2002 totaled 7,030 million boe (oil and condensates 3,782 million barrels; natural gas 3,248 million boe), increasing by 101 million boe over 2001, due to: (i) new discoveries and extensions (338 million boe), in particular in Nigeria, Kazakhstan, Australia and Italy; (ii) revisions of previous estimates (337 million boe), in particular in Kazakhstan, Angola and Nigeria; (iii) acquisitions (39 million boe), in particular interests in fields in the British and Norwegian sections of the North Sea and Australia; (iv) improved recovery (15 million boe) in particular in Algeria. Increases in proved reserves were offset in part by production for the year and the sale of interests in fields in Italy, Qatar and the British section of the North Sea (96 million boe). The increase in proved reserves allowed to replace 119% of production; this average was 129% without taking into account the effect of rationalizations. The average reserve life index is 13.2 years (13.7 in 2001).

Estimated proved developed reserves at December 31, 2002, amounted to 3,703 million boe (2,241 million barrels of oil and condensates and 1,462 million boe of natural gas) representing 53% of total estimated proved reserves (54% at December 31, 2001).

Exploration and development

As of December 31, 2002, Eni’s portfolio of mineral rights consisted of 1,161 exclusive or shared rights for exploration and development in 37 countries on five continents, for a total net acreage of 281,682 square kilometers (317,283 at December 31, 2001). Of these, 41,578 square kilometers concerned production and development (41,841 at December 31, 2001). Net acreage decreased in Italy by 5,333 square kilometers, due to releases, and outside Italy by 30,268 square kilometers, due to releases in particular in Brazil, Pakistan, Egypt, Algeria and Guyana, and sales of mineral rights in Italy and Qatar. Increases were registered in Australia, Norway and Indonesia.

A total of 120 new exploratory wells were drilled (52 of which represented Eni’s share), as compared to 110 exploratory wells completed in 2001 (47 of which represented Eni’s share). Overall success rate was 38.6% (39.1% of which represented Eni’s share) as compared to 36.5% (31.3% of which represented Eni’s share) in 2001.

Exploration expenditure amounted to euro 902 million, of which 93% outside Italy, with a 19.2% increase over 2001. Outside Italy exploration concerned mainly the United States, Kazakhstan, Egypt, Angola, Russia and Brazil; in Italy mainly the deep waters of the Sicily Channel and areas in central-southern Italy.

Investment in the purchase of mineral rights (euro 317 million) concerned primarily the purchase of: (i) a 2.39% interest in the North Caspian Sea PSA, where the Kashagan field is located (Eni is single operator with a 16.67% interest after the purchase) in Kazakhstan; (ii) a 5.6% interest in the Bayu Undan field (Eni’s interest 12.32% after the purchase) in Australia; (iii) an 11.3% interest in the T-Block fields (Eni is operator with an 88.7% share after the purchase) in the British section of the North Sea; (iv) a 7.9% interest in the Mikkel field in Norway; (v) an 8.9% interest in the Liverpool Bay fields (Eni’s interest 53.9% after the purchase) in the Irish Sea (see “Portfolio rationalization’’ below).

17

##### Table of Contents

Expenditure for development and capital goods totaled euro 4,396 million of which 89% outside Italy, increasing by 27.3% over 2001. Development expenditure outside Italy concerned fields in Nigeria, Iran, Libya, Kazakhstan, Angola, Venezuela and the United Kingdom. Development expenditure in Italy referred in particular to the continuation of construction of plant and infrastructure in the Val d’Agri.

Total capital expenditure in 2002 amounted to euro 5,615 million, increasing by euro 1,339 million over 2001, up 31.3%.

Production

In 2002 daily hydrocarbon amounted to 1,472,000 boe (oil and condensates 921,000 barrels; natural gas 551,000 boe) increasing by 103,000 boe over 2001, up 7.5%, despite the 26,000 boe effect of production cuts decided by OPEC and the 8,000 boe effect of the rationalization of Eni’s mineral rights portfolio. The production increase was due to: (i) start-up of fields mainly in Algeria, the United States, Nigeria, Iran, Trinidad & Tobago and Pakistan; (ii) production increases recorded mainly in Algeria, Kazakhstan, the United States, Egypt, Norway, the United Kingdom, Italy and Congo. These increases were partly offset by the production decline of mature gas fields in Italy. The share of production outside Italy reached 78.6% (77.5% in 2001).

Daily production of oil and condensates (921,000 barrels) increased by 64,000 barrels, up 7.5%, due to increases registered outside Italy (up 80,000 barrels) in particular in: (i) Algeria, due to the start-up of the HBNSE/BKNE/RBK fields (Eni’s interest 12.25%) and the reaching of full production at the HBN field (Eni’s interest 34.63%); (ii) Kazakhstan, due to the fact that in the third quarter of 2001 production at the Karachaganak field (co-operated by Eni with a 32.5% interest) was suspended due to a fiscal dispute between Russia and Kazakhstan; (iii) Congo due to the start-up of the Foukanda and Mwafi fields (Eni is operator with a 65% interest) in the second half of 2001; (iv) the United Kingdom, due to the full operation of the Elgin/Franklin fields (Eni’s interest 21.87%). In Italy production increased by 17,000 barrels due to the reaching of full operation of the Monte Alpi pipeline which transports oil produced in the Val d’Agri fields to Eni’s refinery in Taranto. These increases were partly offset by a 33,000 barrels reduction outside Italy due mainly to production cuts decided by OPEC.

Daily production of natural gas (551,000 boe) increased by 39,000 boe, up 7.6%, due to increases registered outside Italy (up 48,000 boe), in particular in Egypt, the United States (in connection with the start-up of the King Kong/Yosemite field — Eni’s interest 50%), Kazakhstan (due to the reasons mentioned above), the United Kingdom and Norway. These increases were offset in part by the production decline of mature fields (down 9,000 boe) in Italy, in particular the Porto Garibaldi/Agostino and Luna fields.

Hydrocarbon production sold amounted to 523.1 million boe. The 14.2 million boe decrease over production was due essentially to natural gas production used for own consumption (8.4 million boe) and input to storage (1.8 million boe). About 75% of oil and condensate production sold (333.4 million barrels) was transferred to the Refining & Marketing division (68% in 2001). About 44% of natural gas production sold (30.68 billion cubic meters) was transferred to the Gas & Power division (47% in 2001).

Portfolio rationalization

Within its portfolio rationalization program aimed at concentrating activities in areas with strong growth potential and where Eni is operator, Eni signed the following agreements:

– |  | the purchase of a further 2.39% interest in the North Caspian Sea PSA in Kazakhstan where the Kashagan field is located (Eni’s share after the purchase 16.67%). The project partners acquired a proportional share of the interests of BP and Statoil that left the project;

– |  | the sale to TotalFinaElf of Eni’s 25% interest in the Gorgoglione concession where the Tempa Rossa field is located, in southern Italy;
– |  | the sale to TotalFinaElf of Eni’s 45% interest in the Alkaliji oil field offshore Qatar (Eni’s only E&P interest in this country) with daily production of 12,000 barrels net to Eni;
– |  | the purchase from Centrica of an 8.9% interest in the Liverpool Bay fields in the Irish Sea and the sale of Eni’s interests in the Armada Area (5.58%), Renee (17.26%), Rubie (4.78%) and Goldeneye (4.5%) fields, with a production of about 5,000 boe/day net to Eni, and associated exploration interests to Centrica. The Liverpool Bay fields (Eni’s interest after the purchase 53.9%) started production in 1995 and produce approximately 110,000 boe/day (59,000 net to Eni). In the British section of the North Sea, Eni sold: (i) its interest in the Banff (12.4%), Hudson (19.5%) and Otter (19%) oil fields with production of about 5,000 boe/day net to Eni as well as associated interests in the Brent Pipeline System (1.38%) and Sullom Voe Terminal (2.35%) and exploration licenses to Dana Petroleum Ltd; (ii) its interests in the Cook (20%), Janice (18.2%), Pierce (3.7%) and Chestnut (6.3%) oil fields with a production of approximately 8,000 boe/day net to Eni to Oranje Nassau Ltd; (iii) interests in the Pickerill (9.33%), Ravenspurn (14%) and Johnson (6.32%) fields with a total production of approximately 2,000 boe/day net to Eni.

In March 2003 Eni also finalized the purchase of the Norwegian company Fortum Petroleum AS (now Eni Norge AS) (see “Main exploration and development projects’’ below).

Main exploration and development projects

ITALY
A gas discovery was made with the exploration well “Panda 1’’ drilled at water-depth of about 460 meters off the coast of Agrigento, in the south of Sicily. Eni is operator with a 37.5% interest. According to preliminary studies recoverable reserves1 could be around 9-12 billion cubic meters (equivalent to 57-76 million boe). A second exploration well (Panda W-1) was drilled in late 2002 in order to define the field’s potential.

NORTH AFRICA
In Algeria, the fourth oil treatment line in the Hassi Berkine South oil center (HBNS, Eni’s interest 12.25%) in the Algerian desert has started operations, the HBNSE/BKNE/RBN (Eni’s interest 12.25%), Ourhoud (Eni’s interest 4.59%) and ZEA (Eni’s interest 49%) fields have started producing, the HBN field (Eni’s interest 34.63%) reached full production, all these new events brought total production to 285,000 barrels of oil per day.

In Libya, within the joint development of the natural gas, oil and condensates fields in the Wafa area, located in the desert 520-kilometer south west of Tripoli, and of structure C (“Bahr Essalam’’) in the NC-41 offshore permit, 110-kilometer north of Tripoli, contracts were awarded for the construction of centers for hydrocarbon treatment near Wafa and Mellitah on the Libyan coast, an offshore production platform and production and transport infrastructure including an underwater production system for a total of euro 3.2 billion. For further details see “Operating Review of the Oilfield Services and Engineering segment’’.

In Egypt, Eni successfully drilled the new exploration well Tennin 1 in the East Delta Deep Marine permit (Eni is operator with a 50% interest) in the Mediterranean offshore, in front of the Nile Delta, about 80-kilometer north of Damietta. The well was drilled at water-depth of approximately 300 meters, reaching a total depth of over 2,000 meters encountering a gas sand interval of about 60 meters. In test production the well yielded over 4,000 boe/day. A pre-feasibility study is underway for the development of the field, which represents a very important discovery not only for the size of its estimated reserves (between 15 and 30 billion cubic meters of gas, corresponding to 90-180 million boe) but also for the possibility to send its production to the Unión Fenosa Gas liquefaction plant under construction at Damietta (see “Operating Review of the Gas & Power segment — Development initiatives’’).

In Tunisia, a new oil discovery was made with the Baraka South East 1 exploration well in the Tunisian offshore approximately 100-kilometer south-east of Tunis. The well was drilled in waters approximately 90 meters deep and reached a depth of over 2,300 meters. It yielded about 5,000 barrels/day of high quality oil in test production. This is the highest flow rate ever reached with a vertical well in the Tunisian offshore. Development studies are ongoing with an FPSO (Floating Production Storage Offloading) vessel. In the onshore Borj el Kadra concession (Eni is operator with 50% interest) in southern Tunisia a new oil discovery was obtained by the Adam 1 well, expected to start production in the second half of 2003.

WEST AFRICA
In Angola, in Block 14 (Eni’s interest 20%) two offshore oil discoveries were made: (i) one with the Gabela 1 well, which was drilled at a water depth of over 320 meters, penetrating a 25-meter interval of oil-bearing porous rock, and yielded over 1,000 barrels of oil per

day in test production. Geologic and engineering studies are planned in order to define the field’s reserves and the development scenario; (ii) the second one with the Negage 1 well drilled at a water depth of 1,444 meters encountering a 30 meter thick layer of oily sands at the depth of 2,990 meters. During test production the well yielded over 8,600 barrels/day. The Tombua 3 well was also drilled with its sidetracks, all of which showed presence of hydrocarbons, maximum production was over 10,500 barrels of oil/day. In Block 15 (Eni’s interest 20%) located offshore about 350-kilometer north-west of Luanda, a new oil discovery was made with the drilling of the Reco-Reco 1 well, which was drilled at a depth of 3,798 meters and yielded about 3,000 barrels/day in test production. Always in Block 15 the Mondo 2 and Mavacola 2 wells were drilled. Mondo 2, drilled at a water depth of 748 meters allowed to discover a 93 meter thick layer of mineral rich sandstones at a depth of 2,200 meters.

In Congo, the new thermoelectric power station at Djeno was inaugurated. The plant, that has a 25 megawatt power capacity, required an investment of dollar 32 million and was completed in 13 months by Eni and ChevronTexaco. The power plant is fired with associated gas from the offshore fields of Foukanda, Kitina and Djambala (operated by Eni with a respective 65, 35.75 and 65% interest) located 65 kilometers from the coast and producing a total of 26,000 barrels of oil per day. Gas is separated onshore at the Djeno terminal close to the new power plant. The project represents the first example of use and exploitation of associated gas otherwise flared in Congo. The project is part of Eni’s program in Congo and in other West African countries aimed at reducing gas flaring and at using it in power generation. In Block Marine X, operated by Eni with a 90% interest, two appraisal wells were drilled, Awa Marine 2 and Paloukou Sud Marine 5. In the Loango concession, operated by Eni with a 50% interest, a seismic and reprocessing campaign was performed aimed at better evaluating the field’s potential and its nearby structures.

In Nigeria, in the OML 118 deep offshore permit (Eni’s interest 12.5%) two appraisal wells were successfully drilled in the Bonga SW oil field at a water depth of about 1,300 meters that allowed for the start of the pre-feasibility study for the development of the field. The Bonga SW 2 well yielded 4,200 barrels/day up to a maximum of 11,000 barrels/day in test production. In the OPL 316 deep offshore permit (Eni is operator with a 50.19% interest) while continuing the drilling of the ABO 4 development well, new deep levels were discovered. The feasibility study is underway, production from these new deep levels will entail synergies with the ABO field. In December 2002 the EA field in the OML 79 permit (Eni’s interest 12.86%) started producing at a rate of 40,000 boe/day (5,000 net to Eni). In the OML 63 onshore permit (Eni is operator with a 20% interest) the Obama Deep appraisal well, drilled at a depth of over 5,300 meters, met a level mineralized mainly with liquid hydrocarbons. The well yielded 4,170 barrels/day in test production and was completed and linked to the Pirigbene facilities.

In Mauritania, the appraisal campaign was completed for the Chinguetti discovery (Eni’s interest 35%) with the drilling of two appraisal wells and a new hydrocarbon discovery was made with the Banda 1 exploration well.

NORTH SEA
In Norway, in March 2003 Eni purchased Fortum Petroleum AS, the Norwegian subsidiary of the Finnish company Fortum Oy. The acquisition entailed a total investment of dollar 975 million, corresponding to the fair value of the company’s assets (of which dollar 256 million were paid for its net equity and dollar 719 million for its net borrowings assumed). Fortum Petroleum’s assets are located in the Norwegian section of the North Sea, in particular they consist of interests in the Aasgard (7%, in this field Eni already holds a 7.9% interest), Brage (12.26%) and Heidrun (5.12%) producing fields and also in Mikkel (7%, in this field Eni already holds a 7.9% interest) presently under development and Goliath (15%, operated by Eni with a 25% interest) still to be developed. In addition, Fortum Petroleum holds interests in important gas transmission infrastructures such as Haltenpipe (5%), Heidrun Gas Export (5.12%) and Aasgard Transport (5%) linking the Aasgard and Heidrun fields to the Norwegian coast. The company also holds an interest in Franpipe (1.29%) and the related

21

##### Table of Contents

Dunkerque terminal (0.84%) in France and in Europipe II (3.66%) for natural gas transmission to the German coast. At the end of 2001 Fortum Petroleum had proved and probable reserves of approximately 202 million boe, half of which were natural gas. In 2002 its daily production amounted to 39,000 boe; in 2003, production is targeted to over 40,000 boe/day. This transaction is part of Eni’s strategy of upstream growth by strengthening its presence in key areas and increasing interests in already held assets in order to generate operational synergies. With this acquisition Eni’s hydrocarbon production in Norway is expected to increase by 40%.

REST OF WORLD
In western Australia, Eni acquired two exploration permits WA-326-P, operated by Eni with a 100% interest, and WA-328-P, operated by Eni with a 66.7% interest. Eni will perform seismic surveys for 1,215 kilometers in the first permit and for 3,015 kilometers in the second permit. Eni was also awarded the WA-25-L production licence (where Eni is operator with a 65% interest) where the Whollybutt offshore oil field is located. Production is expected to start in the second quarter of 2003.

In Azerbaijan, work started for the construction of the Baku-Tblisi-Ceyhan pipeline (Eni’s interest 5%) linking Baku to the Turkish port of Ceyhan through Georgia, which will allow to transport some of the oil produced in the Caspian Sea area to the Mediterranean Sea. The pipeline will be 1,740-kilometer long with a transport capacity of one million barrels/day, is expected to start operating in 2005 and will cost about dollar 3 billion.

In Croatia, Eni and INA (the Croatian national company) signed an agreement for the development of the natural gas reserves discovered offshore Croatia by INAGIP, a 50-50 joint venture between Eni and INA. The fields discovered (Ivana, Ika, Ida, Annamaria and Marica) hold recoverable reserves of 20 billion cubic meters of gas (120 million boe). Their development will entail the drilling of 18 directional wells, the construction and installation of 9 platforms at a water depth of 60 meters and the laying of underwater sealines for a total length of 120 kilometers. Total investment in the project is about euro 320 million. Production will start at the end of 2004. In the same concession a new gas discovery was made with the Katarina 2 well.

In Indonesia, five wells were drilled in the fields of Ranggas, Gandang and Gendalo, in the Rapak and Ganal area (Eni interest 20%) in the offshore east of Kalimantan. Three wells were drilled in the Ranggas oil and gas field, at a water-depth of 1,590 meters, the R4 field flowed at a daily rate of more than 8,000 barrels of oil. The 2A well drilled in the gas and condensates field of Gandang, at a water-depth of 1,710 meters confirmed the extension of the field. In the gas and condensates field of Gendalo, the G3 well, drilled at a water-depth of 1,550 meters flowed at a daily rate of about one million cubic meters/day of gas and about 2,000 barrels/day of condensates.

In Iran, within the development of phases 4 and 5 of the natural gas South Pars field in the Persian Gulf (Eni is operator with a 60% interest), a contract was awarded for dollar 1.2 billion for the construction of four natural gas treatment plants with an overall capacity of 56 million cubic meters/day of gas. Construction of the plants is expected to be completed by 2005. In January 2003 the Balal field started production with an expected daily production of about 6,000 barrels in year 2003.

In Kazakhstan, within the North Caspian Sea PSA (Eni’s share 16.67%) in the Kazakh offshore, the second appraisal well (KE-3) in the Kashagan field confirmed the importance of the discovery allowing to define the amount of recoverable reserves of oil in 7 to 9 billion barrels, that could reach 13 billion barrels with gas reinjection techniques. The third appraisal well (KE-5) yielded over 7,500 barrels/day, while the testing phase is starting of the fourth appraisal well (KE-4). On June 30, 2002 the consortium and the Kazakh authorities declared the saleability of reserves from this field. At the end of December 2002 the Kashagan development plan was filed with the Kazakh authorities. The front-end engineering for the first development phase is underway.

In a block near the Kashagan field within the same contractual area and under the same PSA, a new oil discovery was made in the Kalamkas structure. The Kalamkas-1 exploration

well was drilled to a depth of 2,360 meters and yielded over 2,300 barrels/day in test production. Drilling was performed in very shallow and extremely environmentally sensitive waters.

In Pakistan, in August 2002, Eni signed a production contract agreement for a term of five years for the Manchar exploration licence in the Khirtart Foldbelt area covering an area of 2,435 square kilometers (Eni is operator with a 55% interest). In the Middle Indus Basin Eni obtained a 33.33% interest in the SW Miano (II) concession for a three year term over an area of 1,238 square kilometers. Government authorized the development of the Zamzana natural gas field (Eni’s interest 17.75%). The development project is well underway and startup is expected in the fourth quarter of 2003. On December 30, 2002 early production started in the natural gas Bhit field (Eni is operator with a 40% interest), full production should be reached by the second quarter of 2003.

In the United States, in the Green Canyon 516 Block (Eni’s interest 50%) in the deep waters of the Gulf of Mexico 240-kilometer south-west of New Orleans, production started at the King Kong/Yosemite natural gas fields, only thirteen months from the decision to develop them and eight months after the discovery of Yosemite, reaching a peak of 25,000 boe/day (12,000 boe net to Eni). The development of these two fields, operated by Eni, was obtained by drilling at a water depth of 1,170 meters three underwater wells linked to the Allegheny platform (Eni’s interest 100%) located at a 25-kilometer distance. Recoverable reserves from the two fields amount to 16 million boe net to Eni. Expenditure net to Eni amounts to approximately dollar 90 million. In Green Canyon Block 562, located 290-kilometer south of New Orleans, the delimitation well of field K2 (operated by Eni with an 18.17% interest) was successfully drilled at a water depth of 1,100 meters to a depth of 7,800 meters, and allowed to estimate at over 100 million barrels the recoverable reserves of the field. Production is expected to start in 2004.

Storage

Natural gas storage activities are performed by Stoccaggi Gas Italia SpA (Stogit) to which such activity was conferred on October 31, 2001 by Eni SpA and Snam SpA, in compliance with article 21 of Legislative Decree No. 164 of May 23, 2000, which provided for the separation of storage from other activities in the field of natural gas.

Exploration activities

Storage services are provided through eight storage fields located in Italy, based on nine storage concessions(2) vested by the Minister of Productive Activities. In 2002 following optimization measures on existing fields that increased capacity by 13% (from 6.3 to 7.1 billion cubic meters), higher storage volumes have been made available for cyclic modulation service.

In implementation of its decision No. 26 of February 27, 2002, with decision No. 49 of March 26, 2002 the Authority for Electricity and Gas determined tariffs for modulation, mineral and strategic storage services for thermal year 2002-2003, starting on April 1, 2002 and effective retroactively from June 21, 2000. Stogit filed an appeal against both Authority decisions with the Regional Administrative Court of Lombardia requesting their cancellation.

Gas & Power

With the purchase in joint venture with German company EnBW of 97.81% GVS, one of the largest regional operators in natural gas in Germany where it transports and sells approximately 7 billion cubic meters of gas per year, Eni enters a large natural gas market and consolidates its European leadership.

The agreement for the purchase of a 50% interest in Spanish natural gas company Unión Fenosa Gas, with an investment of euro 440 million, is an important step in Eni’s strategy of international expansion of gas activities. With this transaction Eni strengthens its presence in the Spanish natural gas market, which presents significant growth prospects and where Eni intends to increase its market share. In line with its expansion strategy on Spanish markets, Eni started its 15-year long supply of 1.2 billion cubic meters/year of LNG to the electric company Iberdrola.

The Public Purchase Offering of approximately 56% of the shares of Eni’s subsidiary Italgas at a price of euro 13 each is part of Eni’s strategy of rationalization and international development in the natural gas area. The public purchase offering was successfully closed on January 27, 2003. Now Eni holds 98.285% of Italgas share capital and is squeezing out the remaining outstanding shares.

Within its program of development of electricity generation capacity at Eni’s industrial sites, work started for the construction of a new combined cycle power plant at Ferrera Erbognone (Pavia) with a capacity of 1,030 megawatts and for the upgrade of the Ravenna power plant with the installation of two new combined cycle groups for a total capacity of 780 megawatts.

Rationalizations achieved generated cost savings of euro 58 million.

Natural Gas

Supply of natural gas

In 2002, Eni’s Gas & Power division supplied 62.33 billion cubic meters of natural gas, in line with 2001.

Volumes of natural gas from domestic production accounted for 20% of total supplies (23.3% in 2001) with a decrease of approximately 2 billion cubic meters over 2001.

Natural gas volumes supplied outside Italy represented 79.7% of total supplies (76.6% in 2001) with an increase of 1.87 billion cubic meters over 2001, up 3.9%, in particular due to higher purchases from Norway (3.73 billion cubic meters) and the Netherlands (0.55 billion cubic meters), due to the starting in October 2001 of purchase contracts signed in 1997 with Norwegian and Dutch suppliers (targeting approximately 6 and 4 billion cubic meters/year, respectively). Contracts with Norwegian suppliers became fully operational in 2002, while those with Dutch suppliers will reach full operation in 2003. These increases were offset in part by a decrease in supplies from Algeria (2.04 billion cubic meters) and Russia (0.89 billion cubic meters).

In 2002 a total of 1.43 billion cubic meters of natural gas were input to storage.

Sales of natural gas

In 2002, natural gas sales in primary distribution (60.76 billion cubic meters) decreased by 1.20 billion cubic meters over 2001 (down 1.9%), due to lower sales in Italy (6.33 billion cubic meters, down 10.7%), offset in part by higher sales in Europe (5.13 billion cubic meters, up 167.1%).

In a more and more competitive market, the decrease in natural gas sales in Italy (6.33 billion cubic meters, down 10.7%) was essentially due to a decline in sales to wholesalers (5.69 billion cubic meters, down 18.5%) following the progressive alignment to ceilings set by Legislative Decree No. 164/20001, the concentration process ongoing in this segment and the mild weather of November and December 2002. Also sales to industrial customers declined (0.92 billion cubic meters, down 6.0%) due to the weak economic situation and the interruption of interruptible supplies due to cold weather in early 2002. These declines were offset in part by increased sales to thermoelectric customers (0.28 billion cubic meters, up 2.2%) due to new supplies to power stations, whose effects were offset in part by lower sales following interruptions of supplies to customers with interruptible contracts.

The increase in sales in Europe (5.13 billion cubic meters, up 167.1%) was due to the progressive coming on line of long-term supply contracts with operators of the natural gas market (Plurigas, Edison, Dalmine and Cir Energia) and the start of LNG supplies to Spanish electric company Iberdrola (0.37 billion cubic meters) related to the 15-year supply contract of LNG with volumes corresponding to 1.2 billion cubic meters/year.

Sales of natural gas in secondary distribution in Italy (7.84 billion cubic meters) decreased by 0.28 billion cubic meters, down 3.5%, due mainly to mild weather, whose effects were offset in part by the approximately 119,000 units increase in the number of customers served (5.68 million as of December 31, 2002). At December 31, 2002 municipalities served were 1,197 (1,186 at December 31, 2001).

Within its strategy of rationalization and development of its natural gas segment also a international level and in line with plans announced, Eni’s Board of Directors in its meeting of November 25, 2002, decided to launch a public purchase offering on all Italgas SpA ordinary shares outstanding not owned directly or indirectly by Eni, corresponding to approximately 56% of share capital. Eni offered a unit price of euro 13 per share, to be fully paid in cash and including a 25.7% premium over the weighted average of the last month and a 19.1% premium of the official price of the working day preceding the day of the announcement of the offering.

The public offering was closed on January 27, 2003 with the purchase of 189,340,323 shares corresponding to 97.189% of shares subject to the offering (194,817,383) and 54.326% of Italgas SpA share capital represented by 348,523,506 shares. Payment of the price of shares presented (euro 2,461 million) was effected on February 6, 2003. Italgas shares were withdrawn from the Mercato Telematico Azionario from February 7, 2003.

Summing up with the 153,206,123 shares already directly and indirectly held by Eni SpA, Eni now owns a total of 342,546,446 Italgas shares, representing 98.285% of share capital. As the conditions provided for by article 111 of Legislative Decree No. 58 of February 24, 1998 have been met, with notice published on February 4, 2003, Eni declared its willingness to squeeze-out the shares that did not adhere to the public offering. Such purchase right was exercised on March 25, 2003 without residual offering at the price of euro 13 set by an expert named by the President of the Court of Torino. Eni’s outlay is expected to amount to approximately euro 78 million.

Within its strategy of alliances with municipalities and with companies managing multiservices for local governments, Eni acquired in partnership with Acea SpA a 46.2% interest in Ages SpA, the municipal service company operating in Pisa. Eni’s expenditure amounted to euro 42 million.

Sales in secondary distribution outside Italy (3.79 billion cubic meters) declined by 3.1% (3.91 billion cubic meters in 2001).

Transmission

Eni transported 73.67 billion cubic meters of natural gas in Italy, an increase of 4.09 billion cubic meters, up 5.9% over 2001, due to increased volumes transported on behalf of third parties (7.70 billion cubic meters, up 67.5%), offset in part by the decline in volumes transported on behalf of Eni’s primary distribution (3.61 billion cubic meters).

Development projects

Eni and EnBW (Energie Baden-Württemberg AG, the third German operator in electricity) acquired through a 50/50 German joint venture (EnBW-Eni Verwaltungsgesellschaft mbH) a 97.81% interest in GVS (Gasversorgung Süddeutschland GmbH), the fourth operator in the German gas market. The remaining 2.19% interest is the object of a put option open to minorities, which can be exercised before September 30, 2004 at the same price conditions. The EnBW-Eni joint venture also acquired a 47.57% interest in EBS, a company in which GVS holds a 51% interest, which owns interests in companies in the area of natural gas distribution and co-generation. GVS transports and markets about 7.4 billion cubic meters of gas per year to local distribution companies serving about 750 municipalities in the south-western areas of the country through an approximately 1,880-kilometer long gas pipeline network. In 2001-20022 it generated revenues of about euro 1.5 billion and net income of about euro 59 million. On December 17, 2002 the European Commission authorized this transaction provided that the parties accept to terminate in advance of maturity the long-term supply contracts entered by local natural gas distributors and GVS or any EnBW subsidiaries. In summary, Eni and EnBW are expected to deploy their best efforts so that GVS offers a withdrawal right to its customers (which they can exercise one time only in one of two contract years of their choice — 2004 or 2006 for the contracts expiring in 2008 and 2005 or 2007 for contracts expiring in 2015). The closing of the transaction took place on December 27, 2002 for a total amount of euro 704 million for the joint venture. The partners financed the transaction through a capital increase of about euro 178 million (euro 89 million net to Eni); for the remaining part EnBW-Eni made recourse to financial markets. With this interest in GVS, Eni enters a large natural gas market and confirms its leading role in Europe.

Eni and Gazprom hold equal shares in Blue Stream Pipeline Company BV, a company established to build, finance and operate the gas pipeline linking the Russian to the Turkish coast of the Black Sea. The gasline will transport natural gas produced in Russia which will be sold jointly by Eni and Gazprom in Turkey to the Turkish company Botas under a contract expiring in 2026. The overall project is worth about dollar 2.4 billion and entails two parallel underwater lines, each 380-kilometer long and a compressor station at Beregovaya on the Russian coast of the Black Sea. Laying, which reached a record depth of 2,150 meters, was completed in February 2002 for the first line and in June 2002 for the second line; the compressor station is expected to be completed in the second

half of 2003. Testing of the two underwater lines and of the by-pass managed by the compressor station was completed. The system was ready for operation by December 30, 2002. Commercial operations are expected to start in 2003. Volumes transported and sold are expected to increase progressively from 2003 onwards and to reach approximately 16 billion cubic meters per year (8 billion net to Eni).

Within its strategy of international expansion of gas activities on March 14, 2003 Eni reached a final agreement with Spanish company Unión Fenosa SA for the purchase of a 50% interest in its subsidiary Unión Fenosa Gas. This transaction will be achieved through a capital increase of Unión Fenosa Gas of euro 16 million (corresponding to 50% of its share capital after the increase to be entirely financed by Eni) with a surcharge of euro 424 million, bringing Eni’s total investment to euro 440 million after the granting of authorizations by the relevant antitrust authority.

Unión Fenosa Gas is active in natural gas supply and sale to final users and to power generation companies. It holds a 25-year supply contract, with an option for a 25 year extension, involving 4 billion cubic meters per year with the Egyptian Natural Gas Holding Company (EGAS) and is building a liquefaction plant with a capacity of over 7 billion cubic meters per year near Damietta, on the Egyptian coast. In May 2002 Unión Fenosa Gas signed an agreement with the Government of Oman to develop a joint venture in the gas sector, including the participation in the construction of a new liquefaction plant in Oman, which is expected to start operations from 2006. From then onwards, a contract will guarantee 2.2 billion cubic meters per year for a 20-year period. In addition, it has two LNG Time-Charters contracted for 25 years and holds a 21% and a 50% interest in the Reganosa and Sagunto regasification plants, which will start operations in 2005.

Unión Fenosa Gas will benefit from the liberalisation of the Spanish gas market which is expected to increase by an average of over 10% per year in the next five years and to reach 42 billion cubic meters by 2010. The company targets a 15% market share while also developing on international markets, in particular through the sale of approximately 2.5 billion cubic meters/year to Unión Fenosa SA’s combined cycle power plants.

Eni signed an agreement with the Portuguese government providing for the postponement of the IPO of Galp Energia (Eni’s share 33.34%) to December 31, 2003, thus postponing also to June 30, 2004 the related six-month period available to Eni to exercise its option to purchase a proportional number of Galp Energia shares (12% of its share capital) if the IPO should not take place before December 31, 2003. In 2002 Galp Energia distributed 3.3 billion cubic meters of natural gas, while in secondary distribution it sold 550 million cubic meters.

In January 2003, Tigaz (a subsidiary in which Eni holds 50% interest) further strengthened its position in the natural gas distribution market by purchasing from the Hungarian national company MOL a majority stake in four distribution companies (Mol-Gàz, Zsàmbèrkgàz, Gerecsegàz and Turulgàz) active in the central-northern areas of Hungary for approximately euro 80 million. These companies supply an aggregate of 150,000 customers distributing 400 million cubic meters of natural gas to 407 municipalities. This purchase will be finalized after the concession of authorisations by relevant authorities.

Regulatory framework

Primary distribution

In 2002 a ceiling on imported or produced natural gas input into the national gasline network for sale came into force in Italy as per article 19, line 3 of Legislative Decree 164/2000, which set the maximum allowed limit for each operator to 75% of total domestic consumption in the first regulated year. This limit is reduced by 2 percentage points for each year following 2002 until it reaches 61%. In 2003 a limit on direct sales to end customers corresponding

29

##### Table of Contents

to 50% of domestic consumption will come in force. Both percentages are calculated net of own consumption and, in the case of sales, also net of system losses. A control of respect of ceilings is performed at the end of the first three-year regulated period and later each year by comparing the three-year average allowed percentages for each ceiling with the effective limit reached by each operator in the same period.

On July 17, 2002, the Authority for Electricity and Gas adopted decision No. 137 concerning “guarantees regarding the free access of operators to the natural gas transmission network and rules for the preparation of network codes’’, in implementation of article 24, line 5 of Legislative Decree No. 164/2000. Decision No. 137 established priority criteria for the assignment of transmission capacity at entry points from international networks into the domestic network for a period no longer than five years. In particular it recognises priority access to take-or-pay contracts entered into before 1998, within the limit of the average daily contractual quantity. There is therefore no guaranteed access priority for the whole contractual flexibility. In fact, take-or-pay contracts entered by Eni before 1998 envisage Eni’s right, in its quality of purchaser, to withdraw daily amounts larger than the average daily contractual amount; this contractual flexibility provided by the difference between the maximum daily amount Eni is entitled to and the average contractual daily amount is used in particular in winter. In the event of congestion at entry points, natural gas volumes not receiving a priority are assigned available transmission capacity on a pro-rata basis. Decision No. 137 establishes a transitional regime according to which for thermal year 2002-2003 access priority is granted also to two thirds of the difference between maximum contractual daily amounts and average daily amounts. For thermal year 2003-2004, priority will be granted to only one third of that difference. On November 6, 2002 Eni filed a claim with the Regional Administrative Court of Lombardia requesting the annulment of decision No. 137/2002 as Eni considers this decision non consistent with the overall European legislative picture, especially with reference to Directive 98/30/CE and Legislative Decree No. 164/2000.

On November 21, 2002 the Italian Antitrust Authority concluded the inquiry started on request of Blugas SpA concerning Eni’s alleged violation of competition rules, and acquitted Eni for the specific case of Blugas (deriving from the fact that in the spring-summer of 2001 Eni partially accepted Blugas’s request to access the network) but judged that Eni had violated access rules by giving priority access to Italian purchasers with which Eni had entered supply contracts with volumes supplied at entry points into the Italian network. The Antitrust Authority considers that these contracts infringe the rationale of article 19 of Legislative Decree No. 164/2000 which defines the limits for volumes to be input by a single operator into the national network. Given this infringing behavior and the lack of clarity of Italian regulations and Eni’s availability to increase the transmission capacity of gaslines outside Italy, the Antitrust Authority imposed on Eni a symbolic fine amounting to euro 1,000 and requested Eni to submit “a report indicating measures to be taken to eliminate infringing behaviors with specific attention to the upgrading of the transmission network or equivalent actions’’. Eni filed this report on March 6, 2003. On February 5, 2003 Eni filed a claim with the Regional Administrative Court of Lazio in Rome requesting the annulment of the measures taken by the Authority.

In order to meet the medium and long-term demand of natural gas in particular of the Italian market, Eni entered long-term purchase contracts with producing countries that have a residual average term of approximately 17 years. Existing contracts, which in general contain take-or-pay clauses, will ensure a total of about 66 billion cubic meters of natural gas per year (Russia 28.5, Algeria 21.5, Netherlands 10 and Norway 6) by 2008. Overall natural gas volumes under contract amount to approximately 1,118 billion cubic meters. To date natural gas supply contracts have not entailed the application of take-or-pay clauses. Natural gas imports for the next few years have been programmed based on the highest flexibility allowed by such contracts, assuming that access capacity to the Italian network will be available in accordance with said flexibility. If there arises a congestion in access to the Italian network, this assumption implies a revision of the current network code (as established by the Authority with decision No. 137), also taking into account the claims filed by Eni and other operators.

Based on the best estimates currently available despite regulatory uncertainties, Eni does not consider it necessary to accrue a contingency reserve for any penalty payment related to take-or-pay clauses in supply contracts.

Secondary distribution

With decision No. 122/2002, the Authority for Electricity and Gas changed the tariff regime for natural gas distribution and supply to eligible customers which had been defined in decision No. 237 of December 28, 2000. Decision No. 122 keeps into account the decision of the Regional Administrative Court of Lombardia of June 13, 2001, which accepted the claim of the Association of natural gas distribution companies against the parameters used by the Authority in determining the cost of capital employed in order to quantify the revenue cap of said companies. Decision No. 122 introduced the method of revaluated historical cost for the determination of capital employed for those companies that are provided with audited financial statements starting from the year closing before January 1, 1991, such as Italgas, as an alternative to the parameters defined in decision No. 237/2000.

Law Decree No. 193 of September 4, 2002, in force from September 5, 2002, and turned into Law No. 238/2002 among other things prevented any increases in natural gas distribution tariffs to customers consuming less than 200,000 cubic meters/year and in electricity tariffs to eligible customers until November 30, 2002. Decree No. 193, while confirming tariffs in force before August 2002, prohibited the application of tariff increases set by the Authority for Electricity and Gas for the September-October 2002 period and suspended increases foreseen for the November-December period. As concerns the September-October period in particular, the Authority had confirmed the current tariff for natural gas distribution. On October 31, 2002, the Council of Ministers indicated to the Authority further criteria for the determination of tariffs. Based on this Decree, the Authority will: (i) define, calculate and update electricity and gas tariffs also after the opening up of markets to eligible customers in order to ensure a regular and gradual access to the free market of final users that are non eligible customers; (ii) define methods for updating tariffs with reference to variable costs that minimize the impact of inflation by providing for updating schedules adequate to the objective of reducing the effects of energy prices on inflation, but safeguarding the functioning of energy producing companies and the competitivity of the producing system; (iii) define criteria for allocating the costs deriving from social support measures, in order to reduce the aggregate net cost of interventions as much as possible and to ensure neutrality in the application of tariffs to the various groups of users. Consistently with this decree, the Authority: (i) with decision No. 195 of November 29, 2002 changed the methods for periodically updating the tariff components of electricity and natural gas related to the changes in international prices of fuels and raw materials. Such changes concern updating schedules (from every two months to every three), the duration of the reference period for the calculation of changes in average international prices as compared to the application quarter (from the preceding six months to the preceding nine months). The invariance threshold, beyond which tariffs are updated, remained at 5%. These changes caused the confirmation of tariffs defined in July until December 2002; (ii) with decision No. 207 of December 12, 2002, it decided that companies selling natural gas through local networks can maintain the conditions applied to non eligible customers at December 31, 2002. In addition, that these companies can propose their own new contract offers and offers determined according to the criteria established by the Authority adequately advertising them before March 31, 2003 (such offers must be published on the companies web page, on at least one widely sold newspaper and on the Official Gazette of their region or autonomous province).

Transmission

Under Regional Law No. 2 of March 26, 2002, the Sicilia Region introduced an environmental tax on owners of primary pipelines (operating at a maximum pressure of over 24 bar) in

31

##### Table of Contents

Sicily. The purpose of the tax is “to finance investments aimed at reducing and preventing potential environmental damage caused by pipelines containing natural gas’’. The tax for 2002, based on the volume of the gas pipelines, has been fixed at a rate of euro 153 per cubic meter for pipelines on public land and euro 137.70 per cubic meter for pipelines on private land. The tax is payable from April 2002 and the amount due by Snam Rete Gas SpA for 2002 totaled approximately euro 97 million. The amount of the tax can be changed by the Region with special ruling before December 31 of each year. Otherwise the tax is deemed to remain the same plus the official rate of inflation as published by ISTAT.

In order to protect its interests, Snam Rete Gas: (i) on July 30, 2002, filed a claim with the European Commission aimed at opening a proceeding against the Italian Government, with the further option that the European Commission after the first inquiry phase, can request the Court of Justice to suspend the application of the regional law with an urgent ruling; (ii) notified the Sicilia Region its request for reimbursement of taxes paid, as a first step to the furthering of the dispute and warned the Sicilia Region not to make use of those sums expecting final rulings; (iii) on October 18, 2002, as circumstances materialized constituting tacit rejection of the request for reimbursement, filed a claim with the Tax Commission of Palermo aimed at obtaining a definitive and rapid decision ascertaining the legitimacy of the tax.

The Authority for Electricity and Gas, although acknowledging that the tax burden is an operating cost for the transmission activity, subjected its inclusion in tariffs to the final ruling on its legitimacy by relevant authorities. Therefore, with decision No. 146/2002 the Authority published two sets of tariffs: one, in force, that does not take into account the tax and the second one including it, that will be automatically applied with retroactive effect should the tax be judged legitimate.

In September 2002 Snam Rete Gas filed a claim with the Regional Administrative Court of Lombardia requesting the immediate application of tariffs including the tax. With ruling of December 20, 2002, the Court judged the tax at variance with European rules and therefore did not accept Snam Rete Gas’s claim. In December 2002, Snam Rete Gas suspended payments based on authoritative legal counsel and of said Court ruling. Payments effected until November 2002 totaled euro 86.4 million.

In January 2003 the Sicilia Region presented an appeal to the Council of State against the ruling of the Regional Administrative Court of Lombardia for the part that states the variance of the regional law with European rules. For cautionary reasons, Snam Rete Gas did not record the recovery of costs borne in its accounts, taking into account the uncertainties on the future evolution of this dispute and the time necessary to reach a final judgement.

With decision No. 128/2002 published on July 11, 2002, the Authority approved the tariff proposal submitted by GNL Italia SpA on March 28, 2002 for the 2002-2003 thermal year regarding the use of the Panigaglia LNG terminal. In order to encourage the development of new re-gasification terminals, with ruling 91/2002 published on May 16, 2002, the Authority set out regulations governing access to LNG terminals in the event of the construction of new facilities and of the expansion of existing facilities.

Power Generation

Eni operates in electricity generation and sale through EniPower, a company owning five thermoelectric power stations with a capacity of approximately 1,000 megawatts located at Eni’s refineries in Livorno and Taranto and at Eni’s petrochemical sites of Brindisi, Mantova and Ravenna.

In 2002, sales of electricity amounted to 5,004 gigawatthour, of which approximately 27% was sold to other Eni divisions. Sales of steam amounted to 9,302,000 tonnes. Eni sold 1,744 gigawatthour of purchased electricity to eligible customers.

In Ferrera Erbognone, near Pavia, work started for the construction of a new combined cycle power station, the first one to be built in Italy after the liberalization of the electricity market, with a capacity of about 1,030 megawatts, which will be able to produce about 6.8 billion kilowatthour/year. This power station will also produce steam for industrial use and will be fired mainly with natural gas, using also the refinery gas produced by the nearby Eni plant. The investment for the construction of this power plant amounts to euro 550 million to which euro 170 million should be added for the construction of the fuel oil gasification plant to be built in the nearby refinery. The completion of the first 390 megawatt unit and its startup is expected by the end of 2003. The investments included in Eni’s program for the reduction of the environmental impact of Eni’s plants in the Ferrera Erbognone and Sannazzaro de’ Burgondi areas will allow to reduce emissions of sulphur oxides by about 3,700 tonnes per year and the traffic of tankers on roads by 20,000 units per year.

Work started for the construction of two new combined cycle units with a total capacity of 780 megawatts in the Ravenna thermoelectric power station, which will reach a total power of over 970 megawatts and is targeted to produce about 6.4 billion kilowatthour/year. This power station will also produce steam for industrial use and will be fired with natural gas. The construction of this power station will entail an investment amounting to approximately euro 380 million and will provide relevant environmental benefits by reducing to zero air emissions of sulphur oxides (2,317 tonnes in 2001) and particulates (71 tonnes in 2001). The completion and start-up of the first unit is scheduled for late 2003.

Capital expenditure

In 2002, capital expenditure in the Gas & Power segment totaled euro 1,315 million, increasing by euro 250 million over 2001, up 23.5%, and related to: (i) development and maintenance of Eni’s primary and secondary natural gas transmission network in Italy (euro 606 million); (ii) the program for expanding power generation capacity (euro 426 million), in particular the Ferrera Erbognone and Ravenna power stations; (iii) the construction of the Greenstream pipeline (euro 236 million) transporting natural gas from Libyan fields in Wafa and Structure C of NC-41 permit operated by Eni to Sicily.

Refining & Marketing

The organizational and industrial restructuring of the Priolo-Melilli refinery pole in Sicily is an important step in Eni’s strategy of downsizing its refining system, aimed at better balancing its own production with demand and increasing supply flexibility.

Within its program for the restructuring of its distribution network in Italy, aimed at reaching European standards in terms of average throughput and services to customers, Eni sold 246 service stations, closed down 549 service stations and upgraded its main network with the purchase of about 150 owned and leased service stations. Average throughput in Italy increased by 3.9% (from 1.643 to 1.707 million liters). Agreements were reached for the sale of another 330 service stations in Italy that are going to be finalized in 2003.

Eni continued its strategy of strengthening its presence in selected areas in Europe where logistical and operational synergies can be attained and the Agip brand is well known, by purchasing 61 service stations in France, 40 in central-eastern Europe, while agreements are going to be finalized for the purchase of 313 service stations in Spain, southern Germany and south-eastern France.

Streamlining and divestments allowed to reduce costs by euro 60 million.

Supply and trading

In 2002, a total of 59.50 million tonnes of oil were purchased (58.51 in 2001), of which 34.04 million tonnes from Eni’s Exploration & Production segment, 17.06 million tonnes under long-term contracts with producing countries, and 8.40 million tonnes on the spot market. Some 25% of oil purchased came from North Africa, 24% from West Africa, 17% from the North Sea, 12% from the Middle East, 10% from countries of the former Soviet Union, 8% from Italy, and 4% from other areas. Some 27.26 million tonnes were resold, representing an increase of 4.56 million tonnes, up 20.1%, over 2001. In addition, 5.06 million tonnes of intermediate products were purchased (4.18 in 2001) to be used as feedstocks in conversion plants and 16.57 million tonnes of refined products (15.23 in 2001) sold on markets outside Italy (10.16 million tonnes) and as a complement to own production on the Italian market (6.41 million tonnes).

Agreement on Priolo

Within Eni’s strategy of downsizing its refining system, aimed at better balancing its own production with demand and increasing supply flexibility, Eni and Erg agreed in October 2002 to confer the Priolo (Eni) and Melilli (Erg) refineries in Sicily, as well as their power stations to the newly established company Erg Raffinerie Mediterranee Srl (Eni’s interest 28%). Eni and Erg hold put and call options on Eni’s interest expiring in 2006 at a set price. This operation, authorized by the Italian Antitrust Authority, includes a four-year processing contract under which Erg Raffinerie Mediterranee will process about 2 million tonnes/year of crudes from Eni and will provide to Eni refined products obtained therefrom at a set price. Following this agreement, processing on own account is targeted to decline by about 7.5 million tonnes in 2006.

Processing

Refinery intake processing on own account in Italy and outside Italy (37.73 million tonnes) declined by 2.26 million tonnes, down 5.7%, due mainly to the reduction in refining capacity (one million tonnes, targeted at 1.6 million tonnes) due to the sale of refining capacity to Tamoil in 2001 and the finalization in 2002 of agreements with Erg relating to the conferral of the Priolo refinery (approximately 1.3 million tonnes, targeted at 7.5 million tonnes in 2006) to Erg Raffinerie Mediterranee. The overall balanced capacity utilization rate of wholly owned refineries was 99% with a 2 percentage point increase over 2001 including processing on account of third parties, essentially due to the better balance of refining capacity and demand deriving from the agreement on the Priolo refinery. About 37.4% of all oil processed on own account came from Eni’s Exploration & Production division (29.1% in 2001).

Ceska Rafinerska

Eni holds a 16.33% interest in Ceska Rafinerska (CRC) which owns and manages two refineries, Kralupy and Litvinov, in the Czech Republic with a total refining capacity of about 8 million tonnes/year.

In 2002 the CRC partners approved a plan for the refinery to supply a service of oil processing on account of its partners in proportion to their respective interests. This plan will be operational in second half of 2003. Previously CRC partners purchased refined products from the refinery in proportion to their respective interests.

Distribution of refined products

Sales of refined products (52.02 million tonnes) decreased by 1.22 million tonnes, down 2.3%, mainly due to lower retail and wholesale sales (1.10 million tonnes), lower sales to Eni’s Petrochemical segment in Italy (0.41 million tonnes).

Purchase/sale of service stations

Within its strategy of repositioning in downstream activities in Italy and to selectively develop outside Italy in consolidated areas with significant growth prospects, Eni closed the following transactions:

– |  | in Spain in equal shares with its Portuguese partner Galp Energia (in which Eni holds a 33.34% interest) Eni bought the whole distribution network of TotalFinaElf made up of 186 service stations, with a total throughput of 620 million liters/year, and a storage site with a capacity of over 100 million liters located on the Spanish Mediterranean coast. The agreement also includes the sale by Eni of 195 service stations in Italy (with a total throughput of 270 million liters/year) and by Galp Energia of 111 service stations in Portugal (with a total throughput of 260 million liters/year) to TotalFinaElf;
– |  | Eni purchased from Tamoil refined products distribution activities in central-eastern Europe; in particular 23 service stations in the Czech Republic, 11 in Hungary and 6 in Slovakia with a total throughput of about 45, 15 and 11 million liters per year, respectively. After the purchase, Eni’s market share will increase from 4.1% to 5.7% in the Czech Republic, from 5% to 5.7% in Hungary and from 2.2% to 3.4% in Slovakia;
– |  | Eni signed with Shell an agreement for the sale of 86 service stations in Italy and the purchase of 91 service stations outside Italy. The 86 Agip service stations (including 3 motorway service stations) are located mainly in central-northern Italy with a total throughput of approximately 119 million liters/year. Of the 91 service stations taken over 56 are located in southern Germany (with a total throughput of 180 million liters/year) and 35 in central-eastern France (with a total throughput of 93 million liters/year) in areas with high economic return where Eni intends to increase its market share counting on a well established brand and operational synergies. These transactions have been approved by the relevant authorities;

– |  | in January 2003 Eni signed an agreement for the purchase of the Spanish distribution network of Saras Energia SA (a Spanish subsidiary of the Saras group) which includes 130 service stations with total throughput of about 320 million liters/year and a storage site with a capacity of about 56 million liters, located in Gijon in northern Spain. The deal which was approved by relevant authorities will enable Eni to increase its presence in downstream oil in Spain, becoming the 4th oil company operating in the country with a 5% market share.

Within its strategy of leaving Africa, Eni finalized the sale of its distribution network in Nigeria (242 service stations).

Retail sales in Italy

Sales of refined products on retail markets in Italy (11.14 million tonnes) decreased by 500,000 tonnes, down 4.3%, due mainly to sales and closures of service stations (641 units) within the network streamlining process. Eni’s market share decreased by 2.2 percentage points from 39.7 to 37.5%, while average throughput grew by 3.9% from 1,643,000 liters to 1,707,000 liters.

At December 31, 2002, Eni’s retail distribution network consisted of 7,710 service stations (approximately 65% of which wholly owned), a 641 unit decrease over December 31, 2001, due to closures (549 service stations) related to the rationalization process of Eni’s domestic distribution network, and divestments (246 service stations) mainly related to the agreements defined with Tamoil in 2001, whose effects were offset in part by the opening of 51 new service stations and the positive balance of acquisitions and expirations of lease contracts (103 units). In 2002 Eni sold approximately 1,100 service stations to independent contractors with whom lease contracts were signed under the IP brand name.

The improvement in the quality of services to customers led to a further expansion of the automation process of the domestic network with the system of corporate credit cards active in about 76% of the whole network (about 94% of Agip service stations) at December 31, 2002 (60% at December 31, 2001).

On March 1, 2002 Eni launched its “high fidelity 2002’’ campaign which allows customers accessing self-service outlets provided with an electronic card to obtain price discounts as a function of the total amount of purchased fuel. This initiative was quite successful and lead to the distribution of 2.5 million fidelity cards which contribute to customers’ brand loyalty and use of self-service facilities.

In November 2002 Eni started selling in its Agip branded service stations in Italy a new diesel fuel with low environmental impact named BluDiesel, containing only 10 parts per

million of sulphur (10 mg/kg) and allowing for cleaner injection and protection of the fuel burning system in cars, better combustion and faster start up even at low temperatures, anticipating by seven years the European regulations on this issue. The BluDiesel campaign gives greater value to the potential of Eni’s integrated system (refining, logistics and distribution) selling in a traditionally undifferentiated market a well identifiable and branded product, aimed at meeting the requirements of consumers that pay more attention to the environment and greater care to their cars.

Sales of BluDiesel started in November 2002, by year-end 1,500 service stations were selling the new product which was well accepted by customers all over Italy. BluDiesel sales amounted to 35,000 tonnes. On the ordinary service stations network where BluDiesel is sold, average sales amounted to 20-25% and peaked in some instances at 50% of total gasoil sales.

Retail sales outside Italy

Retail sales in the rest of Europe amounted to 2.57 million tonnes and increased by 100,000 tonnes, up 4.0%, due to the purchase of service stations in France (following agreements signed in 2001 with TotalFinaElf) and in central-eastern Europe. Retail sales in Africa and Brazil (1.44 million tonnes) declined by 270,000 tonnes, down 15.8%, due mainly to the sale of Eni’s distribution network in Nigeria and to the streamlining of the distribution network in Brazil.

As of December 31, 2002, Eni’s retail distribution network outside Italy consisted of 3,052 service stations, decreasing by 304 units over December 31, 2001, due to the sale of service stations, in particular in Nigeria (262 service stations) and closures of mainly leased service stations in Brazil (101 service stations) and Switzerland (31 service stations), whose effects were offset in part by the purchase of 61 service stations in France and 40 in central-eastern Europe in the last part of the year.

Wholesale sales and other sales

Sales on wholesale markets in Italy (10.64 million tonnes) decreased by 600,000 tonnes, down 5.3%, due mainly to lower sales of gasoil for heating purposes. Market share decreased by 1.7 percentage points from 25.6 to 23.9% due to the higher share of sales of fuel oil to the thermoelectric segment in domestic consumption; Eni’s sales to this segment were not material.

Eni concluded the reorganization of its wholesale activities by concentrating all businesses into one company (Atriplex) that integrates in one central and peripheral commercial structure the segments of large and small retailers and consumers. The business was transferred as of January 1, 2003.

Sales to Eni’s Petrochemical segment in Italy (3.82 million tonnes) decreased by 410,000 tonnes, down 9.7%, due mainly to lower availability of specific refinery products (transfer of the Priolo refinery and standstills at the Gela refinery), while other sales (7.47 million tonnes) decreased by 410,000 tonnes, down 5.2%.

Outside Italy, wholesale sales (5.65 million tonnes) increased by 100,000 tonnes. Other sales (9.29 million tonnes) increased by 770,000 tonnes, up 9%, due mainly to higher sales to oil companies.

LPG

In 2002, retail and wholesale sales in Italy (780,000 tonnes) decreased by 60,000 tonnes, down 7.1%, while market share (20.9%) declined by 1.1 percentage points.

Outside Italy, wholesale sales amounted to 1.78 million tonnes with a decrease of 30,000 tonnes, down 1.7%, due mainly to the process of extension of the natural gas transmission and distribution network in southern Brazil. Market share in Brazil was 21.3% (20.8% in 2001), and in Ecuador it was 37.5% (38.2% in 2001).

Market

In 2002 the demand for petrochemical products was affected by the slowdown of worldwide economy, whose effects were dampened by the build-up of stocks by end users. Margins of petrochemical products declined significantly over 2001, in particular of olefins and elastomers, due to a decrease in selling prices (down 8.1% on average) higher than the decline in prices in euro of oil-based feedstocks (down 1.2% on average). Indications of a return to profitability in 2003 are affected by the high risk of further increases in oil-based feedstocks prices due to geo-political tensions and uncertainties on the future recovery of worldwide economy.

The prices of Eni’s principal petrochemical products decreased on average by 8.1%; the main declines concerned polyethylene (down 13%, in particular HDPE) and elastomers (down 9%, in particular BR and SBR general purpose rubbers).

Segment restructuring and conferral to Polimeri Europa

The persistence of negative market conditions and the structural problems of petrochemicals worldwide, related to overcapacity, made the need for restructuring Eni’s petrochemical

activities compelling. In this context Eni conferred its Strategic Chemicals business to Polimeri Europa (effective from January 1, 2002). This business includes EniChem’s core activities in olefins and aromatics, intermediate products, styrene and elastomers produced in Italy in Brindisi, Sarroch, Ferrara, Gela, Mantova, Porto Marghera, Priolo, Ravenna and Settimo Milanese. Also the research centers of Ferrara, Mantova, Porto Marghera, Ravenna and Novara were transferred, as well as the interests in industrial and commercial companies in Italy and outside Italy and about 6,100 employees. Certain plants affected by management criticalities were not transferred.

In November 2002 Eni started procedures for selling its elastomer business which produces thermoplastic rubber, specialty rubber and latices in Ravenna and Ferrara in Italy, Hythe and Grangemouth in the United Kingdom, Champagnier in France and Baytown in the United States with a total of 1,895 employees. In 2002 the elastomer division generated revenues of euro 581 million and sales of 422,000 tonnes. The due diligence phase is underway.

In 2002 Eni shut down the Porto Torres soda-chlorine plant and the Porto Marghera acetylene plant.

Sales — production

Sales of petrochemical products (6,307,000 tonnes) increased by 194,000 tonnes, up 3.2%, due mainly to the building up of stocks by end users in the first half of 2002, in particular of polyethylene and styrenic polymers. Sales of intermediate products increased significantly.

Production (9,575,000 tonnes) was in line with 2001. The increase in production registered in core business activities was offset by the decline in chlorine, determined by the shutting down of the soda-chlorine Porto Torres plant and by the sale of the polyurethane business (effective from May 2001).

Total nominal production capacity declined by 1%, due to the shutting down of the Porto Torres soda-chlorine plant and sale of the polyurethane business. The average capacity utilization rate calculated on nominal capacity was substantially stable (72.1%).

About 42% of total production was directed to Eni’s own production cycle (41% in 2001).

Oil-based feedstocks supplied by Eni’s Refining & Marketing segment covered 52% of requirements in 2002.

Basic petrochemicals

Sales of basic petrochemicals (3,681,000 tonnes) increased by 97,000 tonnes, up 2.7% over 2001, due essentially to increased sales of intermediates (up 15%) offset in part by declines in chlorine derivatives (down 7.2%). The highest increases were registered in phenol (up 40%) due to higher production available and to increased demand in a situation of limited supply due to standstills and production problems of main competitors.

##### Table of Contents

Aromatics sales increased by 6.8%, due to higher benzene purchases, while olefins sales were in line with those of 2001.

Basic petrochemical production (6,634,000 tonnes) was in line with 2001 (up 0.4%) with different trends in different products, in particular increases in intermediates and declines in chlorine derivates.

About 51% of production was destined to the internal cycle.

Styrene and Elastomers

Styrene and elastomer sales (1,178,000 tonnes) increased by 36,000 tonnes over 2001, up 3.2%, due to a relevant increase in sales of styrenic polymers and stable sales of elastomers, that were particularly affected by the slowdown in demand in some industries, and a decline in styrene monomer (down 2.8%) due to lower products available following plant maintenance standstills.

Higher increases were registered in compact polystyrene (up 7.7%) and expandable polystyrene (up 12.7%) especially due to increased demand in eastern Europe and in polybutadiene rubber (BR rubber up 13.9%). Sales of SBR and TPR rubber declined due to the negative trends in the automobile and shoe industries.

Production (1,565,000 tonnes) increased by 36,000 tonnes. Increases were registered in polystyrene despite the decline in styrene monomer production for the maintenance standstill of the largest production line, and in some elastomers.

Polyethylene

Sales of polyethylene (1,448,000 tonnes) increased by 144,000 tonnes, up 11% over 2001, due to the general increase in all products (in particular LLDPE increased by 15.6% and LDPE by 9.8%).

Production (1,376,000 tonnes) increased by 22,000 tonnes, up 1.6%.

Capital expenditure

In 2002, capital expenditure amounted to euro 249 million, with a decrease of euro 100 million, down 36.2% over 2001 due mainly to the fact that in 2001 Eni purchased (euro 108 million) the gasphase licence from Union Carbide in the Polimeri Europa Brindisi plant. Capital expenditure concerned in particular actions for complying with safety and environmental regulations (euro 135 million), actions for the improvement of reliability and safety of plants.

Oilfield Services and Engineering

With the purchase of Bouygues Offshore Saipem has become a world leader in oilfield services. The combination of Saipem’s recognised construction capabilities supported by technologically advanced vessels and Bouygues Offshore’s powerful engineering and project management expertise will allow to strengthen Saipem’s competitive position in the segment of large EPIC projects for the development of hydrocarbon fields.

In 2002 orders acquired amounted to euro 7.8 billion. Among the major contracts acquired in the year are a dollar 1.7 billion contract (Eni’s interest 25%) for the construction of the fourth and fifth train of the natural gas liquefaction plant at Bonny in Nigeria, which proves the excellence of Eni’s technological skills in the area of natural gas treatment, and a turnkey contract for dollar 662 million net to Eni for the development of the Erha hydrocarbon field in the Nigerian offshore by means of a floating production system.

With the completion of testing construction is concluded only about one year after it started of the Blue Stream underwater gasline for the transport of natural gas from Russia to Turkey through the Black Sea. This is one of the most advanced engineering works in the world for the technical challenges it posed and the techniques it required reaching unprecedented laying depths.

In December 2002 start up activities began at the fractioning units, trains 1 and 2, of the LNG-4 plant at Mesaieed in Qatar, the first plant in the world in terms of capacity. When fully operational the plant will allow Qatar Petroleum to double its LNG production.

Marketing performance

In 2002, Eni’s oilfield services activities were positively affected by the upward trend of oil companies’ demand for services which determined an increase in activity levels and in unit margins in the Offshore construction and Offshore drilling areas. The engineering activity too registered good signs of recovery in demand, in particular in the area of upstream plants for hydrocarbon treatment which show interesting growth prospects and where Eni has strong skills and technical know-how.

Orders acquired (euro 7,852 million) increased by euro 4,136 million over 2001, up 111%, due to the good trend of marketing activities and the purchase of Bouygues Offshore (euro 1,119 million). About 96% of new orders acquired was represented by work to be carried out outside Italy, and 12% by work originated by Eni companies. In the light of the turnover in the year, Eni’s order backlog reached euro 10,065 million at December 31, 2002, with an increase of euro 3,128 million, up 45% as compared to December 31, 2001. Projects outside Italy represented 78% of the total order backlog, while orders from Eni companies amounted to 13% of the total.

Among the most significant orders won in 2002 are:

Purchase of Bouygues Offshore

On July 9, 2002, Saipem completed the acquisition of Bouygues Construction’s 50.8% interest in Bouygues Offshore after receiving the approval of the European Antitrust Authority. Bouygues Offshore is a French company leader in the field of engineering for the oil industry. The cash offer price was euro 60.08 per share. Following approvals from the French and USA market authorities Saipem launched a public offering for the remaining shares held by the public at the same price paid to Bouygues Construction for its majority interest. This public purchase offering on the French market was completed on September 6, 2002 with the purchase of a further 46% interest in Bouygues Offshore (thus bringing Eni’s total amount of voting rights to 96.8%). On September 23, 2002, Saipem performed a repurchase offer followed by a squeeze-out of the minority shareholders. Such procedures were closed on October 30 and Bouygues Offshore shares were withdrawn from the Paris and New York Stock Exchanges. At the end of these procedures Saipem owned 100% of the voting rights and 98.8% of the share capital, the remaining 1.2% is represented by own shares held by Bouygues Offshore for its stock option plans. The total cost of this transaction was euro 906 million (detracted net cash acquired for euro 100 million).

The combination of Saipem’s recognised construction capabilities supported by technologically advanced vessels and Bouygues Offshore’s powerful engineering and project management expertise created a new world leader in the provision of turnkey projects to the oil industry. With this acquisition Saipem reaches a superior competitive positioning in the provision of project management, engineering, procurement and construction services for the development of hydrocarbon fields, with a particular focus on challenging projects in remote areas, deep-water environments and gas-related projects. The new group will be a truly worldwide contractor, with strong local presence in strategic and emerging areas such as West Africa, the former Soviet Union, Central Asia, North Africa, Middle East and South East Asia. Bouygues Offshore is a leader in the onshore and offshore oil and gas production facilities. Other activities include maintenance services, construction of port facilities, and LNG supply. Bouygues Offshore’s main geographic areas of activity are Europe and Africa. The company employs approximately 2,500 engineers.

Other acquisitions

In the first half of 2002 Eni finalized: (i) the purchase from Halliburton Brown & Root Ltd of a 50% interest in European Marine Contractors (EMC), a leader in the laying of large

46

The two 24-inch diameter, 385-kilometer long pipelines have been laid at a record water depth of 2,150 meters. On June 26, 2002 Castoro 8, another vessel of the Saipem fleet, completed the tie-in on the Turkish side. Hydrotest and pre-commissioning activities were completed in December 2002 and the system was ready for operation as of December 30, 2002.

Commercial activity is scheduled to start in 2003.

Capital expenditure

In 2002, capital expenditure amounted to euro 233 million, decreasing by euro 71 million over 2001, down 23.4%, and concerned mainly: (i) the initial conversion phase of Maxita aimed at increasing its flexibility and efficiency and seizing the opportunities of a strongly developing market. The vessel will retain its ability to lay flexible, umbilical lines and mooring systems in deep waters, and will also be provided with equipment for “reel’’, “J’’ and “S’’ laying; (ii) the conversion of the Mystras tanker ship purchased in 2001 into an FPSO system; (iii) upgrade actions of the 5820 package plant employed in the Libyan offshore; (iv) the preparation of the drilling plants operating in Saudi Arabia for Aramco in 2002 and the purchase of equipment to be employed in Astrakhan (Russia).

Corporate Governance and Responsibility

Introduction

A responsible business practice able to combine competitivity and sustainability is an integral part of Eni’s operations.

Eni believes, in fact, that the creation of value for shareholders, especially in the medium to long-term, should be achieved in compliance with the principle of correctness of behaviour towards main stakeholders, which, beside shareholders, include employees, institutions, non governmental organizations, suppliers, customers, trade and financial partners and the communities with which the Eni group interacts.

Eni’s commitment in this sense is embodied in the principles, policies and management behaviours that characterize our Group’s activities wherever they take place and are aimed at promoting a “culture of sustainability’’ and strengthening shareholders’ and stakeholders’ trust.

This challenge projects Eni to frontiers and growth models that allow to combine performance, profits and innovation with constant attention paid to quality of life, standards of work, human rights and sustainable development.

The principles on which our practice is based derive from the values that have characterized our activity since its inception.

Towards a sustainable value

In order to promote greater integration of the principles and values of sustainability and corporate social responsibility within the Eni Group, in 2002 a specific corporate social responsibility unit was created with the task to develop corporate policies and processes for the management of sustainability and for the information on this issue, promoting the engagement of main stakeholders at international and local level. Following an internal assessment performed in the first half of 2002, Eni started a consultation process aimed at identifying priorities and specific actions of corporate social responsibility for the next few years.

Principles

Business ethics

All Eni businesses worldwide must be performed with honesty, integrity and respect for laws in force.

Respect for stakeholders

Eni intends to respect all stakeholders with which it comes in contact during its business operations, convinced that they represent a significant asset for the company.

Workers’ protection and equal opportunities

Eni respects labor rights accepted worldwide and core labor standards set by the International Labor Organization (ILO). Eni therefore ensures the freedom of workers’ union and the right to collective bargaining, rejects any form of forced and child labor and any form of discrimination. In addition, Eni is an equal opportunity employer and ensures an equal treatment based on merit to its employees.

Appreciation of professional skills

Eni acknowledges and promotes the development of employees’ skills and abilities and teamwork, so that individual energy and creativity can find a proper expression for the fulfilment of one’s potential.

Respect for diversity

In its business behaviour Eni respects cultures, religions, traditions, ethnic diversity of the communities where its operations take place and is committed to the conservation of biological, environmental, socio-cultural and economic identities.

Respect for human rights

Eni is committed worldwide within its sphere of operations to respect and support the principles contained in the “Universal declaration of human rights’’ of the United Nations.

Cooperation

Eni is committed to contribute actively to the promotion of the quality of life and the social and economic development of the communities where it operates.

Protection of health and safety

Eni ensures the highest standards of health and safety to its employees and to the communities where it operates all over the world.

Protection of the environment

Eni pays maximum attention to the environment and the ecosystem interested by its industrial activities and makes constant reference to the international conventions on sustainable development endorsed by Italy.

Synthetic Presentation of Results Obtained

Global Compact

Eni took part in various actions aimed at promoting the respect of the principles set by the UN initiative. In particular, in the field of labor standards Eni signed the transnational agreement on Industrial relations and CSR; in the area of environmental protection, the Zero Gas Flaring program first in Nigeria and more recently in the Congo; in the area of human rights, Eni holds systematic consultations with local communities in the various areas of the world where it operates respecting their diversity and their rights and aiming at identifying growth plans that take into account their development requirements and expectations.

In order to promote the conditions necessary to the creation of sustainable and enduring value, Eni is committed first of all to respect the main international conventions and guidelines on ethical, social and environmental behaviour. Under this commitment Eni supports the Global Compact action of the United Nations and its nine basic principles in the field of human rights, labor standards and environmental protection. It also participates in the actions promoted by the European Commission and OECD and by various professional associations (such as OGP, IPIECA, Confindustria, etc.) aimed at favoring best business practices in the field of social corporate responsibility.

In order to ensure consistency in the adoption of behaviors in agreement with a corporate culture and vision of sustainability, Eni relies on a system of internal regulations, a governance model that defines principles and rules for guaranteeing correct behaviour towards stakeholders that foresees adequate distribution of responsibilities and a good balance of management and controls. In 2002 Eni adopted a code on internal dealing and a disclosure procedure on corporate and group activities addressed to markets.

In the area of development of human resources and labor standards, Eni is firmly committed to investing in persons and their continuous training, increasing the value of their skills and abilities, in the conditions and organization of labor and in the quality of management. This commitment aims at favoring creativity and the tendency to innovation that represent an investment in the competitivity and duration of the company, but are also a key for higher productivity, growth and sustainability.

In this direction Eni is promoting actions for enhancing the value of the experience and competence of its human resources, by means, among others, of a new system for the management of human resources, the organization of specific training activities aimed at change management and, in the area of industrial relations, the finalization of the “Agreement on Industrial Relations at Transnational Level and on Corporate Social Responsibility’’ and of innovative management of relations with workers’ unions.

With reference to the issues of sustainable development, in 2002 Eni continued to contribute to the growth and welfare of the communities and countries where it operates while respecting the diversity of local values, and completed a number of development actions (the Roll Back Malaria initiative, agricultural development projects in Nigeria, literacy project in Brazil), paying increasing attention to the evaluation of the global impact of its industrial operations.

In the framework of a policy aimed at adopting energy solutions with the lowest environmental impact possible, Eni also defined and promoted actions for the reduction of emissions of greenhouse gases, including, among others, programs for a wider use of natural gas (as the Blue Stream project and the Zero Gas Flaring program).

Consistent with its objectives of competitivity and industrial and economic sustainability, also as concerns research and innovation, Eni has been working in the search for more efficient and environmental friendly products, technologies and services, such as, in the

49

##### Table of Contents

Exploration & Production segment, the “Level 6 Junction’’ application that minimizes the environmental impact of oil wells and, in the Refining & Marketing segment, the introduction of the new BluDiesel, a virtually sulphur free diesel fuel.

In the search for new business opportunities and technological challenges Eni has always been paying great attention to the route chosen to achieve preset targets and has always been deploying its commitment to the areas and communities of which it feels it is an integral part.

The results achieved in the past few years confirm the resolve of a company engaged in increasing its value through actions ensuring sustainability in the short and long-term.

Results achieved are confirmed by the rating assigned to Eni by financial markets on corporate governance and corporate social responsibility:

– |  | Eni moved from 11th to 5th position among the 50 largest companies in Europe (those forming the Eurostoxx50 index) in the special rating of German company DWS, in cooperation with Déminor, which rates the degree of application of corporate governance principles;
– |  | Eni obtained the maximum ethic rating (EEE-) — confirmed also for 2003 — among companies listed on the Italian Stock Exchange in the rating of the European Investment Agency based on the respect of certain ethical principles set by the United Nations, OECD, ILO and the European Union;
– |  | for the third consecutive year — confirmed also for 2003 — Eni was included in the Ethical Index Euro and Ethical Index Global sustainability rating prepared by the independent financial advisor E. Capital Partners SpA and used to evaluate the social responsibility performance of the largest listed companies by investment funds. Since 2001 Eni is also included in the Top European Performers of the corporate governance rating of Déminor because it interpreted and applied the highest standards of organization of the Board of Directors and its committees.

Corporate Governance

Appropriate conduct

Due to the complex scenario in which Eni operates, the Board of Directors has deemed it appropriate to provide a clear definition of the value system that Eni recognizes, accepts and upholds and the responsibilities that Eni assumes within its group and externally in order to ensure that all Group activities are conducted in compliance with laws, in a context of fair competition, with honesty, integrity, correctness and in good faith, respecting the legitimate interests of shareholders, employees, suppliers, customers, commercial and financial partners and the communities where Eni operates. All those working for Eni, without exception or distinction, are committed to observing these principles within their function and responsibility and to make others observe them. The belief of working for the advantage of Eni cannot be a justification for behaviors contrary to such principles. To this end, Eni has issued a “Code of Conduct’’ whose observance by employees is evaluated by the Board of Directors. The Code is published in Eni’s internet site (www.eni.it).

In September 2002, the German investment company DWS (Deutsche Bank Group) in cooperation with the consulting company Déminor updated its ratings of the degree of application of corporate governance principles in 50 European companies with the highest stock market capitalization included in the Eurostoxx50 index. Eni scored fifth in Europe (eleventh in 2001) and first in Italy, as in 2001.

In its meeting of January 20, 2000 Eni’s Board of Directors resolved to adopt the Self-discipline Code of Listed Companies (the “Code’’). On that occasion, the Board — pursuant to a thorough review of the matter — underscored how Eni’s organizational model is essentially in line with the principles expounded in the Code, as well as with related recommendations issued by Consob.

In accordance with the request of Borsa Italiana SpA, in particular the “Guidelines for the preparation of the yearly report on corporate governance’’ of February 12, 2003, follows information on Eni’s corporate governance systems.

The Board of Directors: competencies, delegate powers and composition

The Board of Directors is the central element of Eni’s corporate governance system. Its responsibilities include the definition, application and updating of corporate governance rules and the determination of strategic guidelines at the Company and Group level. In addition to exclusive competencies entrusted to it by art. 2381 of the Civil Code, the Board makes decisions related to: (i) resolutions to be adopted in Shareholder’s meetings of main subsidiaries; (ii) approval of major sale and purchase transactions as well as conferral of real estate, investments, companies of amounts exceeding euro 26 million as proposed by the Managing Director and

51

##### Table of Contents

exam of the instructions provided to Group companies on these matters for their performance of such transactions.

The Board entrusted the Chairman with powers to conduct strategic international relations and the Managing Director with all managing powers except those that cannot be delegated and those reserved to the Board.

The Board of Directors is made up by 8 members elected by the Shareholders’ Meeting of May 30, 2002 for a three-year term, its mandate expires with the Meeting convened to examine financial statements as of December 31, 2004. In the Meeting of May 30, 2002 the Economy and Finance Minister, in agreement with the Minister of Productive Activities, chose not to appoint one member of the Board as per article 6 of Eni’s by-laws. The appointment of Board of Directors is regulated by article 17 of Eni’s by-laws, which calls for a list vote in order to ensure presence of representatives of minority equity interests on the Board of Directors. The lists of candidates include a resume of each candidate. Board members must comply with the honorability and independence requirements provided for by applicable regulations, as well as the professionalism and experience required for performing their duties with efficacy and efficiency, to which they are expected to dedicate adequate time and resources. In accordance with the provisions of the Code (art. 1.3), information on positions held in other Board of Directors or Boards of Statutory Auditors of listed companies, financial or insurance or large companies by members of Eni’s Board of Directors are listed below under “Positions held by Board members’’.

The Board of Directors is formed by the Chairman, Roberto Poli, the Managing Director, Vittorio Mincato, directors, Mario Giuseppe Cattaneo, Alberto Clô, Renzo Costi, Dario Fruscio, Guglielmo Antonio Claudio Moscato and Mario Resca.

On December 18, 2002, Eni’s Board of Directors, in accordance with the provisions of the Code evaluated the statements presented by Board members and established that non executive Board members are independent as they do not have any economic relationship with Eni and Eni Group companies, with the Managing Director and with Eni’s major shareholder such as to bias their autonomous judgment nor are they close relatives of the Managing Director.

Eni’s by-laws do not indicate a specific frequency of meetings. In 2002 the Board of Directors met 13 times. In the first half of 2003 the Board is expected to meet 7 times. The public is informed of the dates of meetings convened for the approval of periodic reports as provided for by applicable laws.

The Board of Directors defined the rules for the calling of its meetings; in particular, the Chairman convenes Board of Directors meetings, and, in concert with the Managing Director, defines agenda items. Notice is sent by mail, fax or e-mail within five days of the meeting’s date, at least 24 hours in advance in case of urgency. Eni’s by-laws allow meetings held by teleconference.

Board members receive in advance adequate and thorough information on all issues subject to Board evaluation and resolutions.

In 2002 on average 91% of Board members participated to Board meetings and 93% of independent non executive Board members.

Board member compensation is determined by the Shareholders’ Meeting, while remuneration levels of Chairman and Managing Director are determined by the Board of Directors, based on proposals of the Compensation Committee and after consultation with the Board of Statutory Auditors. In line with Consob provisions, the Report of Directors included in Eni SpA statutory financial statements indicates: (i) compensation paid to Board members, Statutory Auditors and General Managers; (ii) subscription rights for Eni shares assigned within three years for no consideration (stock grant) and stock options attributed to the Managing Director (Eni employee) and to General Managers; (iii) number of shares of Eni SpA and of Eni companies held by Board members, Statutory Auditors and General Managers. Information as per (i) and (ii) are included also in the notes to Eni SpA’s financial statements.

On May 30, 2002 the Shareholders’ Meeting determined the annual compensation of the Chairman (euro 250,000) and of Board members (euro 68,000). It also determined a variable

52

##### Table of Contents

compensation up to a maximum of euro 80,000 for the Chairman and euro 20,000 for each Board member to be paid in accordance with Eni positioning as compared to the other seven major international oil companies for market capitalization in terms of total return to shareholders in the reference year. The variable portion of compensation is paid to the Chairman for euro 80,000 or euro 40,000 and to each Board member for euro 20,000 or euro 10,000, respectively, if Eni’s return to shareholders is rated first or second, or third or fourth in the rating of return to shareholders of the seven major oil companies. Below fifth position no variable compensation is paid. In addition, Board members receive euro 1,000 for the participation to each meeting of the Board and of Board committees, along with any expense incurred for performing their duties.

With reference to the powers delegated to the Chairman and Managing Director, the Board of Directors determined their compensation, made up of a fixed and a variable part.

The variable part of the compensation of Chairman and Managing Director, as well as the variable part of the compensation of Eni’s top management (General Managers of divisions and managers holding positions directly reporting to the Chairman and Managing Director) is related to the achievement of specific economic and operating objectives (profitability, efficiency, strategic projects) and share price objectives (price of Eni shares, comparative total return to shareholders). With reference to Eni’s performance in 2001, 47% of the remuneration of the Chairman and of the Managing Director was variable, 41% of that of the top management. The variable part of compensation includes, beside the monetary component, Eni’s stock grant plans (see specific information on stock options and stock grants in the Report of Directors included in Eni SpA’s statutory financial statements).

Board committees

In order to carry out its tasks more effectively, the Board of Directors has instituted three Committees: the Audit Committee and Compensation Committee, which are formed exclusively by independent, non-executive Board members, and the Oil & Gas Committee.

Statutory auditors receive in advance adequate and thorough information on all issues subject to Board evaluation and resolutions.

On December 19, 2001 Eni’s Shareholders’ Meeting modified art. 28 of Eni’s by-laws in order to include the provisions contained in the Decree of the Minister of Justice No. 162 of March 30, 2000, concerning the honorability and professional requirements of auditors of listed companies. The by-laws state that at least two auditors and one substitute auditor are chosen among chartered auditors and must have performed auditing activities for at least three years and that auditors not provided with these requirements must be chosen among those provided with the level of professionalism described in Decree 162/2000. For the purposes of said Decree, the by-laws define as related subjects commercial law, corporate economy and finance, engineering and geology. Eni’s auditors are all chartered auditors.

Special powers of the State — golden share

Eni’s by-laws (published on Eni’s internet site) in its article 6.2, which applies article 2, line 1 of Law Decree No. 332 of May 31, 1994, modified and converted into Law No. 474 of July 30, 1994, attributes to the Minister for Economy and Finance, in agreement with the Minister for Productive Activities, the following special powers: (a) approval or disapproval of the acquisition of material interests representing at least 3% of the share capital of Eni SpA having the right to vote at ordinary shareholders’ meetings; (b) approval or disapproval of shareholders’ agreements or other arrangements (as defined by article 122 of Legislative Decree No. 58 of February 24, 1998) involving 3% or more of the share capital of Eni SpA having the right to vote at ordinary shareholders’ meetings; (c) veto power with respect to shareholders’ resolutions to dissolve Eni SpA, to cause a transfer, merger or demerger, to transfer the registered office of Eni SpA outside Italy, to change the corporate purposes or to amend or modify any of the special powers described in this section; (d) appointment of a Board member and an auditor. The Italian Government made use of the powers described under (a) in order to allow a merchant bank to own shares of Eni SpA to be resold on the market following an IPO; but it never made use of the powers described under (b) and (c).

The exercise of these special powers is regulated by the mentioned law and by a regulation published by the Council of Ministers on February 11, 2000.

Investor relations and information processing

In concert with the launch of its privatization process, Eni adopted a communication policy aimed at promoting an ongoing dialogue with institutional investors, shareholders and the markets to ensure systematic dissemination of exhaustive and prompt information on its activities, with the sole limitation imposed by the confidential nature of certain information. Information made available to investors, markets and the press is provided in the form of press releases, regular meetings with institutional investors and the financial community and the press, in addition to general documentation released and constantly updated on Eni’s internet site and sites of the Group’s main companies. Investor and shareholder relations are handled by special Eni functions.

Information regarding period reports and major operations as well as procedures concerning corporate governance is promptly released to the public, also through the internet site. A specific section of Eni’s site contains all press releases, presentations provided in meetings with the press and financial analysts, notices to shareholders and bond holders and information concerning shareholders’ and bond holders’ meetings, including proceeds thereof. Documents available to the public are mailed on request. Available to shareholders are also a mailbox (segreteriasocietaria.azionisti@eni.it) and a toll-free telephone number (800940924) for requesting information and documents.

Eni is aware that financial information plays a crucial role in the functioning of capital markets and in the creation and maintenance of satisfying relationships between the

company and its increasingly wide area of stakeholders. Eni is also aware that investors’ trust in listed companies is one of the essential elements for the functioning of global economy. Investors must be able to rely on the absolute moral integrity of persons responsible of key positions in companies and on the respect of corporate codes of conduct, procedures and rules. Eni’s commitment to provide investors and markets with truthful, complete, transparent, timely and selective financial information is confirmed by its Code of Conduct, that identifies the fundamental values for the deployment of its activities in the completeness and transparency of financial information, the formal and substantial legitimacy of behaviour of its employees at any organizational level and the clarity and truthfulness of its accounting, in accordance with laws and regulations in force.

On December 18, 2002, Eni’s Board of Directors approved a “Procedure for the disclosure of information to the market concerning Group activities’’ published on Eni’s internet site. The procedure acknowledges the “Guidelines for information to the market’’ issued in June 2002 by the Company Information Forum, defines the requirements for disclosure to the public of price sensitive events (materiality, clarity, homogeneity, information symmetry, consistency and timeliness) and the information flows for acquiring data from Group companies and providing adequate and timely information to the Board and the market on price sensitive events.

Eni’s Code of Conduct defines confidentiality duties upheld by Group employees relating to the treatment of sensitive information.

Development of Human Resources and Working Standards

Eni is committed to creating a work environment based on mutual respect and trust, group spirit, transparency in relations with employees and workers’ unions and oriented to the professional growth of human resources also by means of learning paths aimed at developing skills and favoring learning, generating enduring value and consequently profits and employment. In order to achieve these objectives Eni is implementing an organizational and management model that efficiently supports the Group’s strategic development lines.

Strategies for change

With the incorporation of Snam and AgipPetroli Eni completed a change, started in 1997 with the incorporation of Agip, aimed at transforming Eni from a holding company to an operating company directly governing its core businesses and achieved through the creation of three main divisions: Exploration & Production, Gas & Power and Refining & Marketing, all reporting to Eni’s Managing Director.

The Human Resources and Organization function has been restructured and divided into local areas and service centers, with the governing and guiding functions concentrated in Eni Corporate, consistently with the guidelines of Eni’s new system for the management and development of human resources and with Eni’s organizational model. The organizational structure and operating mechanisms of the Exploration & Production division have been reviewed, both at geographical level and in terms of centralised technical services with the aim of: (i) improving systems for planning and monitoring growth; (ii) optimizing the processes for the evaluation and definition of exploration and development expenditure; (iii) improving the use of technical levers by adopting innovations aimed at increasing the value of projects.

The new system for the management of human resources was completed by introducing methods for the evaluation of managers’ skills and potential. This system allows for a constant improvement of efficiency and the innovation of operating processes in response to competitive challenges and in terms of expected performance. It represents also the premise for a further development aiming at disseminating and preserving the Group’s wealth of skills and experiences (knowledge management).

Communication and training

The management of change determined by the new organizational model and by the new system of evaluation of human resources was supported by specific communication and training actions through which the contents and responsibilities of their respective roles have been communicated to and discussed with senior and junior managers and all employees

involved in relevant management functions, as well as the persons working in the Human Resources and Organization function.

In order to disseminate knowledge and information on Group strategies, policies and activities an intranet portal named MyEni was opened for all Eni employees in Italy and outside Italy.

Industrial relations

Eni has a tradition of positive relationships with workers’ unions with which it always maintained a constant and fruitful dialogue by means of an open and constructive partnership.

In 2002 some important objectives were met: (i) on February 12, 2002 employers and workers’ unions signed the new collective contract for employees in the chemical, pharma-chemical, chemical fibers, ceramics, abrasives, lubricants and LPG segments; (ii) on March 1, 2002, employers and workers’ unions signed the new collective contract for the natural gas and water segment; (iii) on March 14, 2002 employers and workers’ unions signed the new collective contract for the energy and oil segments for a four-year term as concerns norms and regulations and for a two-year term as concerns salaries; (iv) on November 29, 2002, Eni and Italian trade unions (Filcea-Cgil, Femca-Cisl, Uilcem-Uil) and ICEM (the International Federation of Chemical Energy Mine and General Workers’ Union) signed an “agreement on industrial relations at transnational level and on the social responsibility of corporations’’. With this agreement Eni completed the innovation of consolidation process of industrial relations started in June 2001 with the Protocol for Industrial Relations and the new agreement on European Company Committee.

Eni is one of the very few oil and gas companies in the world to have signed an agreement of this kind through which it expresses its commitment to the application and enhancement of its guiding principles, to respecting human and workers’ rights as defined by the international conventions of the International Labor Organization, and to establish a constructive relationship with workers’ unions at a global level.

Employees

At December 31, 2002, Eni’s employees were 80,655 with an increase of 8,250 employees over December 31, 2001 (up 11.4%), as a result of the 9,860 persons increase outside Italy (up 36.3%) offset in part by the 1,610 persons decrease in Italy (down 3.5%).

Employees hired in Italy were 43,682 (54% of all Group employees), of these 41,211 were working in Italy, 2,103 outside Italy and 368 on board of vessels. As compared to 2001, the 1,610 unit decline in employees was due to changes in consolidation (302) and to the balance of persons leaving their job and new hiring (1,308).

The process of efficiency improvement continued with the dismissal of 3,447 persons, of these 2,932 had an open-end contract and 515 a fixed-term contract, and with the hiring of

Sustainable Development

In 2002 expenditure for local communities amounted to approximately euro 49 million, confirming the trend set in the past and consistent with Eni’s expansion in new activities and geographical areas. About 85% of resources were addressed to infrastructure and social environmental actions, about 12% to cultural initiatives and the remaining 3% to actions in the field of health. In comparison with past years, Eni registered a progressive decline in the health field and an increase in social and environmental actions, in line with its increasing commitment to the promotion of sustainable processes.

Being convinced that business performances cannot be separated from a responsible business behaviour, Eni is committed to understanding and respecting the cultural, social, economic and natural environments where it operates and to finding innovative solutions for the protection of the social and natural environments of its areas of work.

In a world where the roles of institutions and communities change rapidly, where the imbalances of globalization of economic processes require the active involvement of all the actors of society, businesses can play a fundamental role in contributing to generate growth and development and a general improvement in the quality of life.

Energy companies, like Eni, have to meet the increasing expectations of communities at local and worldwide level, both in terms of reflection on values and of integration of those very values in their organization, policies and day to day management of their operations.

In this sense, within its strategy aimed at ensuring the sustainability of its operations, Eni considers the establishment of strong cooperation ties with producing countries and local communities, the consolidation of good relations with its stakeholders and the promotion of a proper and efficient policy as concerns health, safety and the environment, foremost priorities.

Eni is therefore committed to providing production skills, to improving the quality of life and to favouring the social and economic development of the areas where it operates by promoting and carrying out projects and initiatives that can develop autonomously and be integrated in the social fabric.

At the same time Eni pays special attention to the protection of health, work safety and a proper management of facilities, as well as to the protection of the environment. In general, Eni’s strategic orientations are aimed at the development of a sustainable energy system in which all its business functions are engaged.

Contributions to local development

Eni contributes actively to the welfare of populations and countries where it operates, trying to identify their real needs that change according to their development level, and to provide adequate and efficient solutions to problems and expectations in order to generate sustainable and enduring value. Its final objective is to contribute to economic self-sufficiency, to favour the transfer of skills and knowledge, to promote dialogue with stakeholders while creating and preserving a climate of trust.

The will and commitment to improve living standards, economic conditions and development opportunities takes its actual form in projects aimed at social development, environmental protection and training, health programs and cultural initiatives, managed directly or jointly with industrial partners and in most cases with the cooperation of local or international non governmental organizations and agencies with a total engagement of local communities.

##### Table of Contents

This process is continuously evolving and is integrated — both at the start and at the end — with an evaluation of expected and achieved results and of impact on the areas, with the aim of constantly improving interventions.

In the following pages we describe the most relevant initiatives carried out in 2002, including the implementation of programs started in past years and new projects (a complete picture of all actions can be found in Eni’s new portal at the web address www.eni.it).

Infrastructure and social environmental initiatives

Eni’s contribution to the sustainable development of the countries where Eni operates takes the form of actions capable of generating welfare in the communities to which they are addressed, but most of all to lay the basis for autonomous growth. This is why, besides meeting the need for social and material infrastructure, Eni has put in place programs for rural development, fostering the creation of small enterprises, also by means of micro-credit schemes, and carried out projects supplying energy to communities and villages that are nor linked to energy distribution networks.

The most significant interventions of 2002 were:

Agricultural development schemes in Nigeria

Agricultural development projects significantly contributed to improving social and economic conditions of the rural communities of the oil-rich Niger Delta area.

Based on the positive results of the Green River Project, a modular and integrated agricultural development project that reached until now about 177,000 persons living in the states of Rivers, Bayelsa, Delta and Imo, Naoc is implementing the Burma Rice Farm project in Bayelsa in agreement with the local government. This three-year agricultural program (2001-2003) aims at reintroducing large scale cultivation of rice in an areas where it had been widespread until the mid-eighties and was later abandoned. In particular the project aims at increasing local crops, reducing imports, increasing employment and recovering grounds non suitable for other traditional crops. The program is carried out on model farms with 50-hectar plots targeting production at about 200 tons per year, corresponding to a third of estimated local requirements. Beside significantly improving the food supply in the area, the project will create new employment opportunities and promote more profitable farming, also disseminating the results obtained among local farmers.

Integrated rural development scheme in Venezuela

This project is part of the social investment program started by Lasmo and later implemented by Eni in favour of communities in the Dación area, in the Anzóategui state. The project aims at improving technical knowledge, organizational skills and financial autonomy of existing farms and small enterprises and promoting the birth of new economic activities.

The implementation of this project has been entrusted to the FUNTAG (Fundación Técnico Agropecuaria de Guanape) Ngo and concerned: (i) technical and financial support to farmers and micro-enterprises; (ii) training in agriculture, transformation of crops and animal husbandry; (iii) organizational support to new production units; (iv) provision of loans by means of a communal rotating fund.

The project supported directly about 100 persons (farmers and small entrepreneurs) and indirectly about 2,000 persons.

Social infrastructure in Kazakhstan

Within the Karachaganak project, in cooperation with its industrial partners, Eni completed the reorganization of the water distribution system in Aksai. At Uralsk, the Kazakh Drama Theater was built, while construction started for a stadium and a center for water sports. Some streets and squares were restructured.

In the area of the capital city, Astana, Eni funded a program for public works and social facilities: a sanatorium was built at Borovoye, a child playing center was opened at Baldauren,

##### Table of Contents

near the Chuchye lake, while other facilities, such as the new national library are still in the construction phase.

Consistently with its commitment to sustainable development, Eni deploys its activities in full compliance with existing laws and the highest international environmental standards, performs actions aimed at reducing environmental impact and promotes nature conservation and protection initiatives. In 2002, beside the Zero Gas Flaring program (see Health, safety and environment below) aimed at reducing greenhouse gas emissions and in particular emissions related to the combustion of gas associated to oil production, the following programs are worth mentioning:

Project for the disposal of solid urban waste in Nigeria

In agreement with the government of the Rivers state, Eni funded the preparation of an integrated program for the disposal of solid urban waste in Port Harcourt, a city whose population trebled in the past ten years. The project, that shall be implemented by the Port Harcourt municipality, concerns the full cycle of solid waste (collection, treatment, recycling and disposal) and is expected to cover 5 phases in 11 years with the gradual introduction of advanced technologies.

After the completion of the first phase, waste management services will cover a population of about 660,000 persons. When fully implemented, the integrated program will cover the whole city, whose population is estimated in 1,250,000 persons. This program will also allow to create employment: 300 persons in the first phase and 500 at full operation.

In the countries where it operates, Eni contributes to the development of training, especially of young people, promoting basic schooling programs, specialized training and vocational training courses in technical-scientific and economic-management subjects in order to favour access to labor markets. Among the main initiatives of 2002 are:

Literacy program in Brazil

“Alfabetizaçao solidària’’ is a program to which Eni collaborates since 2001 with the Ministry of Education, universities and municipalities and many Brazilian and foreign companies. Launched in 1997 in the northern and north-eastern regions, the program is addressed mainly to adolescents living in the Brazilian provinces where illiteracy is most widespread. The program aims at containing school leaving and at providing vocational training by means of specific training courses for the students that have completed the basic literacy phase. The project was quite successful in terms of number of participant students and municipalities. At the end of the first half of 2002 about 1.3 million students attended the courses in over 2,000 municipalities with the cooperation of about 100 Brazilian and international companies and over 200 universities that trained over 150,000 teachers.

Health

Eni’s commitment in the field of health aims at improving health conditions by means of local actions providing basic assistance and infrastructures and at offering an active contribution to the solution or mitigation of the most serious complaints that often become real emergency situations and are one of the major obstacles to the development of peoples and countries. This is why Eni supports cooperation with research institutions and programs organized by international organisms.

Among others, Eni supported in particular international programs for the containment of epidemics, such as malaria and AIDS:

Roll Back Malaria

In the fight against malaria, after the very positive results achieved in Azerbaijan from 1999 to 2001, in cooperation with the World Health Organization, Eni provided its know how and facilities for repeating the program of prevention and control of malaria in the Bayelsa state in Nigeria.

63

##### Table of Contents

As a support to the Nigerian program to fight malaria, in 2002 Eni signed a protocol with the state of Bayelsa and the Ologoama community for the implementation of the Roll Back Malaria program in the Okoroma/Tereke area (Niger Delta) addressing a population of about 5,000 persons.

In the first phase Eni cooperated to: (i) the construction of a properly equipped health center; (ii) the supply of ambulance boats; (iii) the distribution of mosquito nets impregnated with environment friendly insecticide; (iv) the restructuring of the Ologoama water system.

Actions planned for the future include: training of nurses and responsible persons; epidemiologic control; an information campaign to favour awareness and knowledge in the population.

The project is going to be extended to other areas in the light of results achieved.

AIDS prevention

Eni is also strongly committed to the fight against AIDS: it contributes to the “Global Fund to Fight AIDS, Tuberculosis and Malaria’’ in particular to the AIDS prevention programs of the Fund for Sub-Saharan Africa, in particular in Nigeria, aimed at preventing mother-child transmission, expanding access to retroviral drugs and disseminating information. Always in Nigeria, in the Niger Delta region, in cooperation with UNICEF Eni is carrying out a program for the prevention of mother-child HIV transmission.

Among initiatives taken in 2002 the following are worth mentioning:

Restructuring and recovery of the Talanga Hospital in Brazzaville, Congo

With the aim of ensuring functioning and general management of the Talanga Hospital, one of the largest in Congo, Eni and the Lombardia region fostered a cooperation agreement between the Congolese hospital and the Sacco hospital in Milan, specialized in tropical medicine.

The two-year assistance program was completed in 2002. The Italian hospital supplied consultancy and training for doctors, nurses and administrative staff, as well as technical assistance for the maintenance of medical equipment.

This phase was the conclusion of a program of cooperation between Eni and the Congolese authorities, where Eni funded and followed the reconstruction and reorganization of this hospital that was seriously damaged by warfare in 1998.

Basic health assistance in Ecuador

In the Pastaza province Eni is supporting a program for basic health care and hospital care to the whole population of the province. The program aims at developing a network of basic health centers, creating the so called “brigadas de la salud’’, small units made up of doctors and nurses that periodically visit the remotest villages, an airplane-carried first aid unit for emergency cases.

Ongoing and completed actions include: a program for the control of malaria, information campaigns, training courses, community infrastructure projects.

Cooperation with the Italian Anti-cancer League

After having participated in the information and prevention campaign organized by the League and directed to Eni employees, in 2002 Eni funded the League’s campaign against smoking. Consistently with the no-smoking policy adopted by Eni, initiatives were promoted to help employees stop smoking.

Theodora Foundation

In 2002 Eni continued and expanded its support to the Theodora Foundation, established in 1999 to alleviate the sufferings of hospitalized children by means of weekly meetings with “Doctor Dream’’, a group of specifically trained clowns. The Foundation is part of network originated in Switzerland in 1993 and now present in 85 hospitals in 9 countries (in Italy it is present in 7 hospitals). Eni sponsors free shows held at the Gaslini Hospital

in Genoa and is now going to extend its sponsorship to other hospitals in Rome and in Tuscany.

Culture

Eni pays special attention to the artistic and cultural heritage of peoples and countries it gets in contact with, in particular it sponsors initiatives aimed at protecting and maintaining the value of works of art, favoring their diffusion by exhibitions, concerts, restoration and archaeological campaigns.

Among the main initiatives sponsored in 2002 are:

Support of musical institutions

Eni continued to sponsor some of the major Italian musical institutions, such as the Teatro Alla Scala in Milan, the Teatro La Fenice in Venice and the Accademia Nazionale di Santa Cecilia in Rome. It also sponsors the Teatro dell’Opera in Rome and the Teatro Regio in Turin.

Already for a few years Eni has been sponsoring the Ravenna and the Spoleto festivals, two relevant artistic events internationally renowned. It is also sponsoring the concert and opera season of the Teatro Comunale in Ferrara.

Art shows

As part of its fruitful collaboration with the Palazzo Ducale in Genoa, Eni sponsored the exhibition of great Ligurian paintings from the Ermitage that described the relations between Genoa and the court in St. Petersburg in the eighteenth century. Eni also sponsored the “La celeste galeria’’ exhibition in Mantua which reunited for the first time after four centuries many masterpieces owned by the Gonzaga family, now dispersed in museums and collections all over the world.

Protection of health, safety and the environment

Constant attention to the protection of health, safety and the environment, led Eni to review its organization in this area in the light of its new structuring by divisions.

HSE guidelines published in 1999: (i) established principles and policies; (ii) defined roles and responsibilities of Eni corporate and business units; (iii) outlined an organizational scheme of Eni’s management system oriented to continuous improvement.

In order to increase Eni’s commitment to the implementation of these guidelines and the trend to the continuous improvement of sustainability in 2002 Eni created a specific HSE unit with the following tasks: (i) elaborating a plan consistent with Eni’s policies and guidelines; (ii) implementing a management model representing a reference point for all business units; (iii) responding to the increasing challenges of environmental sustainability.

In 2002 Eni’s business units continued to obtain certification of their management systems under the most stringent international standards. Certifications reached a total of 83 and covered all the units most exposed to risks for health, safety and the environment and public safety. At the same time audit efforts continued for controlling efficiency and efficacy of management systems. In 2002, a total of 774 audits were performed by internal and independent auditors.

In 2002, accident rates showed an improvement or remained stable as compared to previous years. In particular the accident index and the accident seriousness rate decreased.

As of December 31, 2002, a total of 1,373 full time employees equivalent worked in the protection of health, safety and the environment. Training continued to play a very relevant role in the management of safety and environmental issues. In 2001 a total of 279,466 hours of training were provided to 68,155 participants.

Creation of a sustainable energy system

Eni’s commitment to a more efficient energy system with lower environmental impact continued in 2002 with a further development of action plans for the reduction of greenhouse gases and the mitigation of the possible impact of climate changes. The progress of the Kyoto Protocol and the implementation of new laws favoring the respect of set objectives for the reduction of emissions at domestic and European level stress the increasing strategic influence of greenhouse gases on the fossil fuel industry. After the Italian government’s endorsement of the Kyoto Protocol, Eni actively participated in the definition of the National Action Plan for the reduction of greenhouse gas emissions. Eni companies implemented a comprehensive plan aimed at: (i) improving and adopting the certification of greenhouse gas emissions; (ii) defining a portfolio of projects for emission reduction; (iii) seizing the opportunities provided by the participation to international emission permits markets; (iv) improving ongoing projects and carrying out new initiatives in accordance with the Kyoto Protocol; (v) preparing a medium to long-term strategy for a sustainable management of greenhouse gases. In this perspective Eni continued its programs for the development of natural gas in Italy and outside Italy by means of technologically advanced projects such as the Blue Stream gas pipeline from Russia to Turkey and the Green Stream pipeline that will allow to increase Italian imports of natural gas. Increased gas availability in Italy will lead to a further expansion of the gas-power integration through high efficiency combined cycles with much lower carbon dioxide emissions than coal and liquid fuels.

Outside Italy, Eni continues to work to the reduction of greenhouse gas emissions from the flaring of natural gas associated to oil production by means of the Zero Gas Flaring projects in Nigeria and Congo. These projects do not only allow the reduction of greenhouse gas emission as compared to the past, but also provide a significant contribution to the sustainable development of producing countries. In Kwale, Nigeria, Eni is building a high efficiency combined cycle power station that will increase the reliability of the local power distribution service.

With an orientation to the medium term, the development of technologies for carbon dioxide separation and its permanent storage in geologic formations is being carried out in an international R&D program with other major oil companies.

Further detailed information on objectives and performances of Eni Group companies are included in Eni’s 2002 Report on Health, Safety and the Environment.

Eni’s activity aims at extending the boundaries of knowledge and promoting the exchange of experience, expertise and know-how, in the belief that technological excellence is an essential factor in competition and economic and industrial sustainability. To this end Eni is constantly striving in the research and development of technologies, services and products with a distinctively innovative character.

In 2002 Eni reviewed the role of research and development in the light of the following guidelines: (i) to increase resources devoted to upstream issues; (ii) to allocate more resources to the development of prototypes; (iii) to support qualified laboratory research in order to direct it to long-term radical innovation.

In accordance with these guidelines, the major turning points achieved have been: (i) the implementation of a new model of innovation which integrates activities aimed at incremental improvement managed by business units with the long-term innovative projects managed by Eni corporate functions by means of a coordination center and the allocation of costs directly to corporate functions for the most innovative projects; (ii) a reorganization of R&D structures aimed at integrating all homogeneous skills and knowledge centers, including the laboratories of the Refining & Marketing division and of Snamprogetti.

In 2002, Eni invested euro 175 million in research and development (euro 203 million in 2001). At December 31, 2002, a total of 1,390 persons were involved in research and development activities (1,500 at December 31, 2001).

In the course of 2002, many technologies were implemented at the industrial level for the first time:

In the Exploration & Production division, an innovative technology (Level 6 Junction) was developed and applied to a well in Nigeria that allows to divide the well in a number of branches while maintaining safety requirements and reducing operating costs and impact on the ground. A new innovative method was developed and applied that does not require invasive inspections of pipes, but is based on indirect measurements capable of locating any obstructions, such as waxes and asphaltenic deposits within flowlines.

In the Refining & Marketing division, marketing of the new formula gasoil “BluDiesel’’ started and certification was obtained from a major German car manufacturer for an innovative “fuel economy’’ lubricant.

In Petrochemicals, improved performance polymers were developed such as linear polyethylene for extensible films and thermoplastic elastomers for the compound area. A new competitive process for the manufacture of ethylbenzene was developed and tested as well as a new catalyst for the manufacture of linear polyethylene.

Many technologies reached an advanced development stage.

In the Exploration & Production segment, initial applications are underway based on original proprietary techniques of CRSS, a new method for the elaboration of geophysical data, that allows a more accurate definition of subsoil imaging. A new integrated IT application named SCREAM was developed which allows for the search of analogue situations in carbonated reservoirs, in existing database or reporting with a very fast access to geomineral data and information with significant reductions of the time necessary to start production. The Corporate research function is developing, among other things, technologies to reduce the density of drilling fluids by means of hollow glass micro spheres and for stopping water infiltration by means of the RPM (Relative Permeability Modifier) polymer.

In the Gas & Power division, the experimenting phase is nearly completed for the “Synthesis of waxes by means of Fischer Tropsch’’ technology used in a pilot plant built at Eni’s Sannazzaro refinery. Use in a pilot plant confirmed the performance of the new partial catalytic oxidation technology for the production of synthetic gas or hydrogen.

At the Taranto refinery construction started of the Eni Slurry (EST) demonstration unit with a 1,200 barrels/day capacity for the upgrading of heavy oils.

Various improvements were introduced in the designing and laying of pipelines, with specific reference to the use of high and very high grade (X-80 e X-100) steel and to advanced telecollection systems for the definition of routes and for the optimization of deep water operations (drilling, field development).

In the Refining & Marketing division, work continued on the quality improvement of fuels, gasoline, gasoils and lubricants, fuels for special use in turbines and oil drilling operations.

Work on environmental issues continued, focused in particular on the reduction of polluting emissions by means of the optimization of the vehicle/fuel ratio and the reclaiming of industrial sites also with biological techniques.

During the year, 50 applications for patents were filed in Italy (65 in 2001).

Eni’s consolidated financial statements at December 31, 2002 showed a net income of euro 4,593 million, with a decrease of euro 3,158 million over 2001, down 40.7%, due to: (i) a euro 1,811 million decrease in operating income (down 17.6%) related in particular to lower refining margins (Brent down 59.4%) and lower natural gas realization prices, a change in the supply/sale mix and lower volumes sold in natural gas primary distribution, as well as higher asset impairment; these negative factors were offset in part by higher international oil prices and improved oil production mix (overall oil realization prices were up 5.2%), increased hydrocarbon production sold (up 4.7%) and lower costs; (ii) the negative change in the balance of net extraordinary income/expense (euro 1,766 million) due to lower gains on disposal of assets (down euro 3,216 million), whose effects were offset in part by lower restructuring charges, in particular in Petrochemicals. These negative changes were partly offset by lower income taxes (euro 402 million), due in particular to a decrease in income before income taxes and lower net financial expense (euro 128 million).

Rationalization and improved efficiency actions led to cost savings amounting to euro 523 million, offsetting almost entirely increases related to salary increases and inflation, as well as increases related to higher activity levels and acquisitions. Cost savings achieved in the 1999-2002 period amounted to approximately euro 1.7 billion, or 50% of the euro 3.4 billion target set for 2006.

(1) |  | Effective from 2002, Eni’s new Gas & Power division is responsible for Eni’s natural gas and electricity generation activities. In the past data of the Natural Gas and Electricity Generation segments were reported separately.

Eni’s net sales from operations (revenues) for 2002 amounted to euro 47,922 million, declining by euro 1,350 million, down 2.7% over 2001, due mainly to lower natural gas realization prices and lower prices for main downstream products, the change in the sale mix and lower volumes sold in natural gas primary distribution, as well as the effects of the translation to euro of financial statements denominated in dollars. These negative effects were offset in part by an increase in international oil prices and improved oil production mix, higher hydrocarbon production sold and higher activity levels in the Oilfield Services and Engineering segment.

Revenues generated by the Exploration & Production division (euro 12,877 million) declined by euro 1,083 million, down 7.8%, due essentially to lower natural gas realization prices

(down 11.1%), the appreciation of the euro over the dollar (up 5.6%) and lower volumes of purchased hydrocarbons marketed (down 51 million boe) due mainly to the transfer of the natural gas trading activity to the Gas & Power division. These negative factors were partially offset by higher international oil prices and improved oil production mix (overall oil realization prices were up 5.2%) and higher hydrocarbon production sold (23.4 million boe, up 4.7%).

Revenues generated by the Gas & Power division (euro 15,297 million) declined by euro 801 million, down 5%, due essentially to lower prices for natural gas, whose effects were partially offset by the transfer of the natural gas trading activity from the Exploration & Production division.

Revenues generated by the Refining & Marketing division (euro 21,546 million) declined by euro 537 million, down 2.4%, essentially due to lower prices for refined products (the retail prices of gasoline and diesel fuel were down 5.9% and 8.7%, respectively) and to reduced sales volumes on both the retail and wholesale market in Italy (overall 1.1 million tonnes, down 4.8%), due to the effect of closures/sales of service stations and lower gasoil sales on wholesale markets.

Revenues generated by the Petrochemical segment (euro 4,781 million) decreased by euro 327 million, down 6.4%, due mainly to the 8.1% fall in the average selling prices of products, partially offset by higher sales (up 3.3%).

Revenues from the Oilfield Services and Engineering segment (euro 4,573 million) increased by euro 1,459 million, up 46.9%, due to increased activity levels.

Revenues generated by the other activities (euro 1,023 million) increased by euro 328 million, up 47.2% due mainly to higher insurance premiums acquired by Padana Assicurazioni and by increased activity levels at Sieco, a company performing general services for Eni Group companies.

|  |  | 34,228 |  |  |  | 35,037 |  |  |  | 34,996 |

Operating expenses (euro 34,996 million) were substantially in line with 2001. Lower supply costs for natural gas, cost reductions resulting from streamlining and increased efficiency and the effect of the appreciation of the euro over the dollar were almost entirely offset by the increase due to salary rises and inflation as well as increases related to higher activity levels and acquisitions.

Payroll and related costs (euro 3,103 million) increased by euro 176 million, up 6%, mainly due to the inclusion in consolidation of Saipem SA (the new name of Bouygues Offshore) in the Oilfield Services and Engineering segment and an approximately 3.8% increase in unit labor cost in Italy. These effects were offset in part by an approximately 2,400 decline in the average number of employees in Italy resulting from the streamlining initiatives undertaken.

(1) |  | Operating income of 2002 prudentially reflects the euro 144 million effect of the reduction in natural gas storage and modulation tariffs following decision No. 49 of the Authority for Electricity and Gas of March 26, 2002. Eni filed an appeal against this decision with the Regional Administrative Court of Lombardia. Pending the result of this appeal, Eni did not record the effects of the new tariff regime on the operating income of the Exploration & Production and Gas & Power divisions. These effects amounted to a euro 271 million decrease on operating income of Exploration & Production division and to a euro 271 million increase on operating income of Gas & Power division.

Exploration & Production

Operating income totaled euro 5,175 million, representing a euro 809 million decrease over 2001, down 13.5%, due mainly to: (i) lower natural gas realization prices (down 11.1%); (ii) higher mineral asset impairment (euro 244 million) in particular in the North Sea and in the Gulf of Mexico; (iii) the effect of the appreciation of the euro over the dollar (up 5.6%); (iv) a decrease in storage and modulation tariffs due to the effects of decision No. 49/2002 of the Authority for Electricity and Gas (euro 144 million); (v) higher exploration costs (euro 94 million). These negative factors were offset in part by: (i) higher international oil prices and improved oil production mix (overall oil realization prices were up 5.2%); (ii) increased hydrocarbon production sold (23.4 million boe, up 4.7%); (iii) gains on disposal of assets (euro 92 million); (iv) cost reductions related to synergies deriving from the integration of purchased companies and streamlining (euro 154 million).

72

##### Table of Contents

Gas & Power

Operating income amounted to euro 3,244 million, a euro 428 million decrease over 2001, down 11.7%, due mainly to: (i) a decline in results of primary distribution related to the effect of a change in the sales mix due to the higher share of sales in Europe related to the progressive alignment to ceilings set by Legislative Decree No. 164/2000, a change in the supply mix and lower sales (1.20 billion cubic meters, down 1.9%); (ii) asset impairment in the distribution of natural gas in Brazil and Argentina (euro 93 million) due to lower profitability prospects; (iii) the payment of the environmental tax established by the Sicilia Region with Regional Law No. 2(1) of March 26, 2002 (euro 86 million); (iv) lower results in the power generation activity resulting from lower sale margins mainly due to the expiration of tax incentives on certain sale contracts for the Livorno and Taranto power stations. These negative factors were offset in part by: (i) higher results in secondary distribution related to higher tariffs and the positive effect of estimates of the impact of the application of decision No. 122/02(2) of the Authority for Electricity and Gas (euro 74 million related to 2001); (ii) lower costs (euro 58 million) related to streamlining, in particular in transport activities in Italy, which were partly offset by salary increases and inflation.

Refining & Marketing

Operating income amounted to euro 321 million, a euro 664 million decrease over 2001, down 67.4%, due mainly to: (i) a sharp decline in refining margins reflecting the unfavorable refining scenario (Brent margin was down 59.4%), related to weak demand, a reduction in Fob/Cif differentials on products that reduced the advantage of refineries based near end markets and the appreciation of the euro over the dollar; (ii) lower margins on oxygenates (MTBE and methanol) related essentially to lower international prices of products; (iii) the fact that in 2001 the positive effect of a decrease in stocks (valued at Lifo) was recorded for euro 36 million as compared to a revaluation of euro 13 million in 2002; (iv) lower volumes sold in wholesale markets in Italy due to a weak economic situation. These negative factors were offset in part by lower costs (euro 60 million) related to streamlining and disposals, offset in part by salary increases and inflation, higher retail margins in Europe, also related to efficiency improvement, offset in part by lower retail sales in Italy due to the the network restructuring process.

Petrochemicals

Operating losses amounted to euro 347 million, a decrease of euro 68 million over 2001, up 16.4%, due mainly to: (i) lower depreciation and amortization charges (euro 162 million) following plant writedowns recorded in 2001; (ii) the fact that in 2001 the impact of price decreases on the evaluation of stocks had been negative for euro 100 million (in 2002 this impact was positive for euro 27 million); (iii) lower costs related to streamlining and disposals (euro 70 million), offset in part by salary increases and inflation; (iv) a 3.3% increase in volumes sold. These positive factors were offset in part by a decline in margins, especially in the first quarter of 2002, related to lower selling prices of products (on average down 8.1%), as compared to a slower decline in prices in euro of oil-based feedstocks (on average down 1.2%), and asset impairment (euro 105 million).

Oilfield Services and Engineering

Operating income totaled euro 298 million, of which euro 302 million related to oilfield services, with a euro 43 million increase over 2001, up 16.9%. Oilfield services recorded an

increase in operating income of euro 46 million due to the contribution of the Blue Stream and Karachaganak projects and to the results obtained by increased activities in West Africa, Saudi Arabia and the Far East, as well as to the contribution of Bouygues Offshore (euro 35 million before the allocation of euro 21 million for the amortization of the difference between purchase price and net equity non attributable to fixed assets). These positive factors were offset in part by the lower profitability of some contracts in the Offshore drilling area. Engineering activities recorded an operating loss of euro 4 million, with a euro 3 million decline, due primarily to higher provisions to the reserve for risks and contingencies on contracts nearing completion (euro 18 million) and the negative outcome of a transaction (euro 8 million), offset in part by increased turnover for 2002, in particular related to the contract for the construction of the Milan-Bologna high speed train tracks. Note that income earned from joint venture projects is accounted for as income on investments in Eni’s income statement. Operating income calculated with the inclusion of this income amounted to euro 23 million (euro 11 million in 2001 in homogeneous terms).

Other activities

This area includes Eni’s corporate and financial overhead costs as well as the operating results of insurance and service businesses (administration, technical services and IT), in addition to those of EniTecnologie SpA, Eurosolare SpA and Tecnomare SpA. Operating losses amounted to euro 189 million (euro 168 million in 2001).

Net financial expense (euro 167 million) decreased by euro 128 million over 2001, due mainly to lower interest rates (three-month Euribor down 1 percentage point) and lower average net borrowings for about euro 950 million.

Net income from investments

Net income from investments amounted to euro 43 million (net expense of euro 7 million in 2001) and represented the balance of income for euro 290 million and expense of euro 247 million. Income from investments concerned mainly: (i) Eni’s share of income on investments accounted for with the equity method (euro 188 million) in particular in the Gas & Power (euro 98 million), Oilfield Services and Engineering (euro 47 million) and Refining & Marketing (euro 40 million) segments; (ii) gains on disposal (euro 57 million) essentially on the disposal of a 10% interest in Qatar Petrochemical Co in the Petrochemical segment (euro 52 million); (iii) dividends from investments accounted for at cost (euro 32 million).

Expense on investments (euro 247 million) concerned: (i) Eni’s share of losses on investments accounted for with the equity method and at cost (euro 223 million), in particular Galp Energia SGPS SA (euro 85 million related to the amortization of the euro 107 million difference between purchase price and net equity); Albacom SpA (euro 37 million) and Inversora de Gas del Centro SA and Distribuidora de Gas del Centro SA (euro 36 million), minor interests in the Exploration & Production (euro 32 million), Oilfield Services and

Gains on disposals (euro 92 million) concerned the sale of mineral assets in the Exploration & Production division within the portfolio rationalization program. Non-recurring losses on investment (euro 36 million) concerned the depreciation of Distribuidora de Gas del Centro SA and Inversora de Gas del Centro SA in Argentina due to lower profitability prospects.

Income taxes

Income taxes (euro 3,127 million) decreased by euro 402 million over 2001, due mainly to a decline in income before taxes and the positive effect (euro 95 million) of the release of the reserve for anticipated amortization as per Law 448/2001, offset in part by the adjustment of the reserve for deferred tax liabilities due to the 10 percentage point increase in corporate taxes (from 30 to 40%) of oil companies in the United Kingdom (euro 215 million).

The 7.5 percentage points increase in tax rate (from 30 to 37.5%) was due mainly to the fact that the gains on the placement of 40.24% of Snam Rete Gas in 2001 were recorded net of substitute tax paid3.

The 4.6 percentage point difference between effective tax rate (37.5%) and statutory tax rate (42.1%) was due to: (i) for 5 percentage points the effect of the application of a favorable tax regime as provided for by certain Italian tax laws (for example the law on dual income tax, Law 383/2001 which provides for fiscal incentives to new investments and Law 448/2001);

(3) |  | The 19% substitute tax paid by Snam SpA on the revaluation and conferral of assets to Snam Rete Gas SpA was recorded as an increase in the book value of these assets in the consolidated financial statements and therefore contributed to determine a gain. Substitute taxes are recorded consistently with the amortization of revaluated assets.

##### Table of Contents

(ii) the effect of the application in 2000 of the voluntary revaluation of assets as per Law 342/2000 for 4.7 percentage points. These effects were partially offset by the higher rate of taxes of foreign subsidiaries (2.7 percentage points) and other reasons (2.4 percentage points).

Income taxes of foreign subsidiaries in the Exploration & Production division amounted to euro 2,093 million, representing a euro 28 million decrease over 2001 reflecting lower income before taxes of foreign subsidiaries with relatively higher tax rates and the recording of anticipated taxes on tax loss carryforwards of Agip Petroleum Co Inc and Agip Exploration & Production Ltd, partially offset by the adjustment of the reserve for deferred liabilities of oil companies in the United Kingdom (euro 215 million).

Minority interest

Minority interest (euro 629 million) increased by euro 161 million over 2001, due mainly to the placement of 40.24% of Snam Rete Gas in late 2001 and higher net income earned by Saipem SpA.

At December 31, 2002, net capital employed totaled euro 39,492 million, representing an increase of euro 199 million over December 31, 2001, due mainly to an increase in net working capital (euro 431 million) offset in part by a decrease in net fixed assets (euro 211 million). The share of the Exploration & Production, Gas & Power and Refining & Marketing divisions on Eni’s net capital employed was 88.3% (90.4% as of December 31, 2001). The debt to equity ratio went from 0.35 at December 31, 2001 to 0.39.

Net fixed assets (euro 33,693 million) were primarily related to the Exploration & Production (58.9%), Gas & Power (21.3%) and Refining & Marketing (9.2%) divisions. Provisions for depreciation, amortization and writedowns (euro 39,712 million) represented 54.1% of gross fixed assets (53.2% at December 31, 2001).

(euro 121 million), 35% of Albacom SpA (euro 115 million), 10.4% of Nigeria LNG Ltd (euro 111 million), 28% of Erg Raffinerie Mediterranee SpA (euro 100 million), 49% of Superoctanos CA (euro 93 million), 49% of Azienda Energia e Servizi SpA (euro 92 million), 50% of EnBW Eni Verwaltungsgesellschaft mbH (euro 90 million) and 50% of Transmediterranean Pipeline Co Ltd (euro 83 million).

Accounts receivable financing and securities related to operations (euro 1,426 million) were made up primarily by loans made by Eni’s financial subsidiaries on behalf of Eni’s operating subsidiaries, in particular by companies in the Gas & Power division (euro 608 million) and in the Exploration & Production division (euro 630 million).

The appreciation of the euro over other currencies, in particular the dollar, in the translation of financial statements denominated in foreign currencies as of December 31, 2002 (the euro was up 18% over the dollar) determined a decrease in the book value of net capital employed of euro 3,180 million, of net equity of euro 2,242 million and of net borrowings of euro 938 million.

The euro 1,195 million decline in tax liabilities and the net reserve for taxes was due to the decline in income taxes related to the decline of income before taxes and to the following: (i) the effects of new tax laws related to the deductions of recognition on a five-year period of the fiscal benefit of losses on investments (euro 441 million); (ii) a new regulation for the payment of excise taxes that anticipated to the end of December the payment of excise taxes on finished products put on the market in the second half of December (euro 404 million); (iii) the reversal of the reserve for deferred taxation that had become redundant due to the release of reserves for anticipated amortization (euro 145 million, net of substitute taxes due in 2003 of euro 54 million). These aspects were offset in part by the increase in the reserve for deferred liabilities of oil companies (euro 215 million) due to the 10 percentage point increase in corporate taxes (from 30 to 40%) of oil companies in the United Kingdom.

The reserve for contingencies (euro 5,522 million) included essentially: the site restoration and abandonment reserve of euro 1,980 million (euro 1,963 million at December 31, 2001), the environmental risk reserve of euro 1,558 million (1,451 at December 31, 2001), the loss adjustment and actuarial reserve for Eni’s insurance companies of euro 593 million (euro 535 million at December 31, 2001), the reserve for disposals and restructuring of euro 354 million (euro 423 million at December 31, 2001), the reserve for contract penalties and disputes of euro 211 million (euro 213 million at December 31, 2001), the reserve for employee retirement and similar obligations of euro 128 million (euro 86 million at December 31, 2001) and the reserve for losses related to investments of euro 106 million (euro 224 million at December 31, 2001).

With the aim of improving motivation and loyalty of Eni managers through the linking of compensation to the attainment of preset individual and corporate objectives, making management participate in corporate risk and motivating it towards shareholders’ value creation objectives, increasing at the same time their contribution to management of the Company, starting in 2000 Eni created stock grant plans offering underwriting of Eni shares for no consideration to those managers of Eni SpA and its subsidiaries as defined in art. 2359 of the Civil Code2 who have achieved corporate and individual objectives.

Stock option rights may not be transferred by the assignee to other persons or entities, and their assignment is firm and irrevocable while they automatically expire in case the assignee decides to terminate employment at Eni within three years from the date the share rights were granted.

The tax regime to which stock grants are subject is the following: at the time of underwriting the value of shares contributes to the taxable income of employees for tax and pension purposes; the taxable value is calculated on the basis of the arithmetic average of official prices of Eni shares on Mercato Telematico Azionario in the month preceding subscription.

to increase the capital stock up to a maximum of euro 3.5 million (or about 0.0875% of current capital stock) by issuing 3.5 million shares, nominal value euro 1 per share for no consideration before July 31, 2001 by withdrawing from the “Reserve for the issue of shares in accordance with art. 2349 of the Civil Code’’. On June 21, 2000 and June 7, 2001 the Board of Directors resolved to increase Eni’s share capital by issuing up to a maximum of 2 and 1.5 million ordinary shares to be offered for no consideration to those managers that achieved preset individual and corporate targets in 1999 and 2000.

In application of the 2002 Incentive Plan, Eni’s Shareholders’ Meeting of May 30, 2002 delegated to the Board of Directors, in accordance with art. 2443 of the Civil Code, the power to increase the capital stock up to a maximum of euro 1.5 million for no consideration (or about 0.0375% of current capital stock) before December 31, 2002 by issuing up 1.5 million ordinary shares nominal value euro 1 per share, by withdrawing from the “Reserve for the issue of shares in accordance with art. 2349 of the Civil Code’’. On July 2, 2002 the Board of Directors resolved to increase Eni’s share capital by issuing up to a maximum of 1.5 million ordinary shares to be offered for no consideration to those managers that achieved preset individual and corporate targets in 2001.

Following the Board’s decisions and Eni’s management performance in the 1999-2001 three-year period, on August 31, 2002, Eni assigned underwriting rights expiring after three years from the assignment date; those rights concern 4,317,500 shares (equal to 0.1079% of current capital stock) subdivided as follows: (i) in 2000 a total of 1,428,550 shares; (ii) in 2001 a total of 1,851,750 shares; (iii) in 2002 a total of 1,037,200 shares. At December 31, 2002 a total of 7,450 underwriting rights expired; at the same date 750,200 shares had been underwritten.

Of rights existing at December 31, 2002, a total of 1,354,750 expire in 2003, of 1,509,100 expire in 2004 and of 1,015,000 in 2005. Eni SpA’s share capital at December 31 2002 amounted to euro 4,001,814,026 represented by 4,001, 814,026 shares, nominal value 1 euro each.

Stock Option Plans

2000-2001

The 2000-2001 Stock Option Plan, described in detail in Eni’s 2001 Annual Report, provides for the exercise of options for the underwriting of Eni shares to be issued by means of the capital stock increase approved by Eni’s Shareholders’ Meeting of August 2, 2000, provided that the arithmetic average of Eni share prices recorded in July 2002 is equal to or higher than euro 16.8. In relation with Eni share price trend in July 2002, options offered for the subscription of 14,369,500 Eni shares to 180 Eni Group managers at the price of euro 12.992 (the arithmetic average of official prices recorded on the Mercato Telematico Azionario in the month preceding the date of the Board’s resolution of September 26, 2000 to increase capital) are no longer exercisable.

2002

Eni’s Shareholders’ Meeting of May 30, 2002 delegated to the Board of Directors the power to increase the capital stock up to a maximum of 15 million own shares (or about 0.375% of current capital stock) for Eni’s 2002-2004 Stock Option Plan to be sold at a price corresponding to the arithmetic average of official prices recorded on the Mercato Telematico Azionario in the month preceding the date of assignation to those managers of Eni SpA and its subsidiaries3, as defined in art. 2359 of the Civil Code, who are in the positions that most contribute to the Group’s performance and are of strategic interest for the Group (314 persons).

The tax regime to which stock options are subject is the following: for the purpose of personal income tax (Irpef) stock option plans are subject to the regime defined by article 48, line

(3) |  | Does not include listed subsidiaries, which have their own Stock Grant plans.

2 letter g-bis of Presidential Decree No 917/1986; consequently the difference between the price of assignment of shares and the market price of shares at the time of exercise does not contribute to personal income. Gains realised on the sale of shares are subject to a 12.50% substitute tax.

On July 2, 2002 the Board of Directors approved: (i) the Stock Option Plan for 2002 which provides for the assignation of a maximum of 5 million options for the purchase of own shares in a 1 to 1 ratio; (ii) the criteria for the selection of managers that are to participate in the Plan; (iii) regulations for the Plan, and delegated to the Managing Director the selection of the assignee managers on the basis of such criteria, before December 31, 2002. Option rights provide to assignees the option to purchase Eni shares at the price corresponding to the mentioned average after three year from their assignation. In case of agreed termination of employment or retirement or death, the assignee maintains the right to exercise underwriting rights within six months from termination of employment, whereas residual rights expire. The sole exception is Eni SpA’s Managing Director who maintains the right to exercise underwriting rights assigned to him until July 31, 2010. In case of termination decided by the assignee or by the company within three years from assignation, all underwriting rights expire. Option rights not exercised before July 31, 2010 expire. Assignees may receive advances from Eni’s brokerage company managing the newly issued shares provided that at the same time the assignees give irrevocable instructions to sell such shares to such company.

At December 31, 2002, a total of 3,518,500 options were offered for the purchase of 3,518,500 own shares at the price euro 15.216 per share, corresponding to said average.

Share buy-back program

In order to increase value for shareholders Eni’s Shareholders’ Meeting on May 30, 2002 resolved to continue the share buy-back program up to a maximum of 400 million own shares, nominal value 1 euro, and increased by euro 2 billion its maximum amount (from euro 3.4 to 5.4 billion). Both limits include shares in portfolio at the Meeting’s date (161.4 million shares, nominal value 1 euro, for euro 2,175 million).

Subsequent events

Relevant subsequent events concerning operations are found in the operating review. In the present context we would like to mention the following:

Settlement with Montedison

On March 6, 2003 Eni and EniChem SpA accepted the settlement proposal presented by Edison SpA for the closing of an arbitration proceeding initiated by Eni and EniChem SpA in 1992 in relation to guarantees given by Montedison SpA and its subsidiaries in connection with the establishment of Enimont. With this settlement Edison SpA accepted to pay EniChem euro 200 million to be paid in four instalments of euro 50 million each, the first one paid on March 6, 2003 and the remaining to be paid each following year with interests accrued; this delayed payment is supported by bank guarantees payable on first request. This settlement concerns expense paid or accrued by EniChem SpA in previous years. It

does not include EniChem’s claim to be indemnified by Edison SpA for any expense related to damage made to third parties by the operation of plants and facilities before Montedison’s conferral, even if occurred later. These are environmental damages claimed by the State and related to the Mantova site and any damage that could be claimed by the State and/or other third parties as alleged consequence of specific environmental damage situations in the Brindisi and Priolo sites. The settlement of any dispute is entrusted to ordinary courts.

Management’s expectations of operations

Trends in 2003 of main outside variables that influence Eni’s results of operations are indicated below:

– |  | worldwide demand for oil is expected to increase over 2002 (up 1.2%) even if the expected rate is lower than the trend registered in the nineties, due to the uncertainties related to global geopolitical tension that affect the recovery of world economy. Eni’s forecast on oil prices in 2003 indicates an average price of Brent corresponding to the price of 2002 (25 dollars/barrel) that reflects the approximately 32 dollar/barrel price recorded in January-February 2003 and a gradual slow down in the rest of the year until it reaches the lower limit set by OPEC for its crudes panel (22 dollar/barrel, about one dollar/barrel less than Brent price), a price in line with the recovery of world economy;
– |  | in 2003 the euro is expected to remain quite strong as compared to the dollar, due to the adjustment process of imbalances in US economy; Eni forecasts an average appreciation of the euro over the dollar of over 10% as compared to the average exchange rate of 2002 (1 euro = 0.946 US dollar);
– |  | assuming normal temperatures, demand for natural gas in Italy is expected to increase by about 5% compared to 2002, due essentially to increased consumption in power generation;
– |  | refining margins are expected to recover compared to the depressed levels of 2002. The magnitude of this recovery will be influenced by the recovery of world economy. In the first two months of 2003 Brent margins were over 3 dollar/barrel (as compared to a nil value in the first two months of 2002) due to international tensions that led operators to build up stocks and to the consumption of fuels for heating purposes, due to a very cold winter in the northern hemisphere.

The following are the forecasts for the production and sales performance of Eni’s main activities in 2003:

– |  | daily production of hydrocarbons, net of the effect of the rationalization of the portfolio of mineral assets, is forecasted to grow as compared to 2002 in line with the planned average growth rate for the 2003-2006 four-year period (approximately 6%). The 2003 increase in production is expected outside Italy due to the contribution of the purchase of Norwegian company Fortum Petroleum and increased production and startups in consolidated areas (Nigeria, Kazakhstan) and recently acquired ones (Australia, Pakistan and Iran);
– |  | volumes of natural gas sold by the Gas & Power division in Italy and Europe are expected to increase by approximately 4% compared to 2002. Volumes transported on behalf of third parties in Italy are expected to increase by over 25%;
– |  | electricity production sold is forecasted at approximately 5,400 gigawatthour, increasing by 8% over 2002; volumes of purchased electricity sold on the market are forecasted at approximately 2,500 gigawatthour (1,700 in 2002);
– |  | total refinery processing intake on own account in Italy and outside Italy is expected to decline by about 4% due to the progressive coming on line of agreements with Erg on the Priolo refinery (targeting a reduction of 7.5 million tonnes/year in 2006). The overall balanced capacity utilization rate of wholly owned refineries is expected to increase (99% in 2002) due to the better balance obtained between refining capacity and demand;

##### Table of Contents

– |  | sales of refined products on retail markets in Europe are expected to remain in line with those of 2002; higher retail sales in the rest of Europe following the purchase of 313 service stations in Spain, France and Germany will be offset by a decline in Italy due to the effects of the rationalization process.

In 2003 capital expenditure is expected to amount to approximately euro 8.7 billion; over 90% of these investments will be made in the Exploration & Production, Gas & Power and Refining & Marketing divisions.

glossary

A glossary of financial and oil and gas terms is available on Eni’s web page at the address www.eni.it/english /notizie/mediateca /glossario_eni.html. Follows a selection of the most frequently used terms.

FINANCIAL TERMS

Leverage It is a measure of a company’s debt, calculated as the ratio between net financial debt and shareholders’ equity, including minority interests.

Roace Return On Average Capital Employed, is the return on average capital invested, calculated as the ratio between net income before minority interests, plus net financial charges on net financial debt, less the related tax effect and net average capital employed.

OIL AND NATURAL GAS ACTIVITIES

Average reserve life index Ratio between the amount of reserves at the end of the year and total production for the year.

Barrel Volume unit corresponding to 159 liters. A barrel of oil corresponds to about 0.137 metric tons.

Boe Barrel of Oil Equivalent. It is used as a standard unit measure for oil and natural gas. The latter is converted from standard cubic meters into barrels of oil equivalent using a coefficient equal to 0.0061 in the case of gas produced abroad and 0.0063 in the case of gas produced in Italy due to their different calorific values.

Concession contracts Contracts currently applied mainly in Western countries regulating relationships between States and oil companies with regards to hydrocarbon exploration and production. The company holding the mining concession has an exclusive on mining activities and for this reason it acquires a right on hydrocarbons extracted, against the payment of royalties to the State on production and taxes on oil revenues.

Condensates These are light hydrocarbons produced along with gas, that condense to a liquid state at normal temperature and pressure for surface production facilities.

Deep waters Waters deeper than 200 meters.

Development Drilling and other post-exploration activities aimed at the production of oil and gas.

Elastomers (or Rubber) Polymers, either natural or synthetic, which, unlike plastic, when stress is applied, return to their original shape, to a certain degree, once the stress ceases to be applied. The main synthetic elastomers are polybutadiene (BR), styrene-butadiene rubbers (SBR), ethylene-propylene rubbers (EPR), thermoplastic rubbers (TPR) and nitrylic rubbers (NBR).

Enhanced recovery Techniques used to increase or stretch over time the production of wells.

EPIC (Engineering, Procurement, Installation Commissioning) a contract typical of offshore construction of complex projects (such as the installation of production platforms or FPSO systems) in which the global or main contractor, usually a company or a consortium of companies, supplies engineering, procurement, construction of plant and infrastructure, transport to the site and all preparatory activities for the start-up of plants.

EPC (Engineering, Procurement, Commissioning) a contract typical of onshore construction of large plants in which the contractor supplies engineering, procurement and construction of the plant. The contract is defined “turnkey’’ when the plant is supplied for start-up.

Exploration Oil and natural gas exploration that includes land surveys, geological and geophysical studies, seismic data gathering and analysis, and well drilling.

FPSO vessel Floating, Production, Storage and Offloading system made up of a large capacity oil tanker including a large hydrocarbon treatment plant. This system, moored at the bow in order to maintain a geostationary position, is in fact a temporary fixed platform linking by means of risers from the seabed the underwater wellheads to the treatment, storage and offloading systems onboard.

Infilling wells Infilling wells are wells drilled in a producing area in order to improve the recovery of hydrocarbons from the field and to maintain and/or increase production levels.

LNG Liquefied Natural Gas obtained through the cooling of natural gas to minus 160° C at normal pressure. The gas is liquefied to allow transportation from the place of extraction to the sites at which it is transformed and consumed. One ton of LNG corresponds to 1,400 cubic meters of gas.

LPG Liquefied Petroleum Gas, a mix of light petroleum fractions, gaseous at normal pressure and easily liquefied at room temperature through limited compression.

Mineral Potential (“Potentially recoverable hydrocarbon volumes’’) Estimated recoverable volumes which cannot be defined as reserves due to a number of reasons, such as the temporary lack of viable markets, a possible commercial recovery dependent on the development of new technologies, or for their location in accumulations yet to be developed or where evaluation of known accumulations is still at an early stage.

Mineral Storage Volumes required for allowing

86

##### Table of Contents

optimal operation of natural gas fields in Italy for technical and economic reasons.

Modulation Storage Volumes required for meeting hourly, daily and seasonal swings of demand.

Network Code A Code containing norms and regulations for access to, management and operation of natural gas pipelines.

Offshore/Onshore The term offshore indicates a portion of open sea and, by induction, the activities carried out in such area, while onshore refers to land operations.

Olefins (or Alkenes) Hydrocarbons that are particularly active chemically, used for this reason as raw materials in the synthesis of intermediate products and of polymers.

Over/Under lifting Agreements stipulated between partners regulate the right of each to its share in the production of a set period of time. Amounts different from the agreed ones determine temporary Over/Under lifting situations.

Possible reserves Amounts of hydrocarbons that have a lower degree of certainty than probable reserves and are estimated with lower certainty, for which it is not possible to foresee production.

Probable reserves Amounts of hydrocarbons that are probably, but not certainly, expected to be extracted. They are estimated based on known geological conditions, similar characteristics of rock deposits and the interpretation of geophysical data. Further uncertainty elements may concern: (i) the extension or other features of the field; (ii) economic viability of extraction based on the terms of the development project; (iii) existence and adequacy of transmission infrastructure and/or markets.

Production Sharing Agreement Contract in use in African, Middle Eastern, Far Eastern and Latin American countries, regulating relationships between State and oil companies with regards to the exploration and production of hydrocarbons. The mining concession is assigned to the national oil company jointly with the foreign oil company who has exclusive right to perform exploration, development and production activities and can enter agreements with other local or international entities. In this type of contract the national oil company assigns to the international contractor the task of performing exploration and production with the contractor’s equipment and financial resources. Exploration risks are borne by the contractor and production is divided into two portions: “cost oil’’ is used to recover costs borne by the contractor, “profit oil’’ is divided between contractor and national company according to variable schemes and represents the profit deriving from exploration and production. Further terms and conditions may vary from one country to the other.

Proved reserves Proved reserves are estimated volumes of crude oil, natural gas and gas condensates, liquids and associated substances which are expected to be retrieved from deposits and used commercially, at the economic and technical conditions applicable at the time and according to current legislation. Proved reserves include: (i) proved developed reserves: amounts of hydrocarbons that are expected to be retrieved through existing wells, facilities and operating methods; (ii) non developed proved reserves: amounts of hydrocarbons that are expected to be retrieved following new drilling, facilities and operating methods. On these amounts the company has already defined a clear development expenditure program which is expression of the company’s determination.

Recoverable reserves Amounts of hydrocarbons included in different categories of reserves (proved, probable and possible), without considering their different degree of uncertainty.

Ship-or-pay Clause included in natural gas transportation contracts according to which the customer for which the transportation is carried out is bound to pay for the transportation of the gas also in case the gas is not transported.

Strategic Storage Volumes required for covering lack or reduction of supplies from extra-European sources or crises in the natural gas system.

Take-or-pay Clause included in natural gas transportation contracts according to which the purchaser is bound to pay the contractual price or a fraction of such price for a minimum quantity of the gas set in the contract also in case it is not collected by the customer. The customer has the option of collecting the gas paid and not delivered at a price equal to the residual fraction of the price set in the contract in subsequent contract years.

Upstream/Downstream The term upstream refers to all hydrocarbon exploration and production activities. The term downstream includes all activities inherent to the oil sector that are downstream of exploration and production activities.

Wholesale sales Domestic sales of refined products to wholesalers/distributors (mainly gasoil), public administrations and end consumers, such as industrial plants, power stations (fuel oil), airlines (jet fuel), transport companies, big buildings and households. Do not include distribution through the service station network, marine bunkering, sales to oil and petrochemical companies, importers and international organizations.

Notes to the Consolidated Financial Statements

1 General

Eni SpA and its subsidiaries (“Eni”) together constitute a fully integrated company operating in the oil and gas, electricity generation, petrochemicals, oilfield services and engineering industries. Eni SpA is the successor entity to Ente Nazionale Idrocarburi, which was established in 1953 as public statutory body to act as Italy’s national oil and gas company. In July 1992, in connection with the privatization program of the Italian Government (the “Government”), the public statutory body was converted into a joint stock company, with the Ministry of Economy and Finance (previously Ministry of Treasury, Budget and Economic Planning) of Italy as the sole shareholder. See Note14 Eni’s Shareholders’ equity for further information regarding share capital.

2 Summary of significant accounting and reporting policies

Basis of presentation

The consolidated financial statements of Eni have been prepared in accordance with Eni’s group accounting policies which are in accordance with principles prescribed by Italian law and supplemented by the accounting principles issued by the Consiglio Nazionale dei Dottori Commercialisti e dei Ragionieri or, in the absence thereof and if applicable, the International Accounting Standards Board. In the absence of indications in said principles, particularly related to the application of the Unit of Production and production sharing agreement methods of accounting, specific criteria for hydrocarbons exploration and production applied internationally have been followed (collectively, “Italian GAAP”). Italian GAAP differs in certain respects from generally accepted accounting principles in the United States (“U.S. GAAP”). A description of these differences and their effects on net income and shareholders’ equity is set forth in Notes 28 and 29. The financial statements have been reformatted from the original Italian statutory financial statement presentation and include certain additional disclosures in order to conform more closely to the form and content of financial statements required by the U.S. Securities and Exchange Commission (the “SEC”).

Principles of consolidation

The consolidated financial statements include the statutory accounts of Eni SpA and all Italian and foreign companies controlled by Eni SpA, directly or indirectly, either by holding the majority of the voting rights or sufficient votes to enable it to exercise control at ordinary shareholders’ meetings. The consolidated financial statements also include, on a proportional basis, the accounts of companies controlled jointly with other partners, except for joint ventures which are accounted for under the equity method. The effects of proportionate consolidation are not material. Insignificant subsidiaries, companies held exclusively for sale and companies in liquidation, if their exclusion does not result in a misrepresentation of the company’s financial condition and consolidated results, are not included in the scope of consolidation. The effects of these exclusions on the whole, are not material.

Investments

Investments in non-consolidated subsidiaries excluded from the consolidation process and in companies where Eni SpA has a 20% to 50% investment, if material, are accounted for using the equity method. Other investments are recorded at cost, adjusted for permanent impairment in value.

Sales of stakes in consolidated subsidiaries

Gains or losses on sales in consolidated subsidiaries are recorded against the income statement for the amount corresponding to the difference between proceeds from the sale and the divested stake of net equity.

Fiscally driven entries and intercompany transactions

The statutory financial statements reflect certain tax-driven entries. The effects of the tax-driven entries and all intercompany balances and transactions have been eliminated in consolidation.

##### Table of Contents

Translation of financial statements of consolidated companies expressed in a foreign currency

Assets and liabilities of foreign consolidated companies have been translated at exchange rates ruling at year-end. Equity accounts of foreign consolidated companies are translated using the historic exchange rates. Income statement accounts of foreign consolidated companies are translated at the average rates for the period. Related translation adjustments are reported as a component of shareholders’ equity. Financial statements used for the translation are denominated in local functional currencies. Monetary assets and liabilities denominated in foreign currencies are translated into euro using the prevailing rate at the balance sheet date. All differences are recognized in earnings in the period.

Accounting principles

Cash and cash equivalent

Eni considers cash and cash equivalent to be its cash on hand and on deposit with banks and short-term investment with original maturities of less than 90 days.

Marketable securities

Marketable securities are stated at the lower of purchase cost or market value and are usually available for sale.

Inventories

Inventories, except for those relating to contract work in progress, are stated at the lower of cost or market value, by excluding the recording of financial expenses and the market value. The cost of inventories of hydrocarbon (crude oil and natural gas) and petroleum products, representing 58%, and 57% of Eni’s inventories at December 31, 2001 and 2002, respectively, is substantially determined by the last-in, first-out (LIFO) method; the cost of inventories of the Petrochemicals segment, representing 18% and 19% of Eni’s inventories at December 31, 2001 and 2002, respectively, is generally determined by the average cost method.

Contract work in progress, representing 9% and 6% of inventories at December 31, 2001 and 2002, respectively, is recorded using the percentage-of-completion method. Payments received in advance of construction are subtracted from inventories and any excess of such advances over the value of work performed is recorded as a liability. Contract work in progress not yet invoiced, whose payment is agreed in a foreign currency, is recorded at current exchange rates at year-end. Future losses that exceed the revenues earned are accrued for when the company becomes aware such losses will occur.

The remaining inventories are determined, generally, by the average cost method.

Fixed assets

Fixed assets are stated at cost as adjusted by revaluations in accordance with various Italian laws; revaluations are included in the consolidated shareholders’ equity. Eni capitalized interest on debt incurred in connection with specific projects. Cash requirements in excess of such debts are satisfied primarily through funds generated and contributed in the period of construction.

Investment grants from Government agencies are recorded in a contra asset account when authorized, if all the required conditions have been met. Such grants are amortized over the useful life of the assets.

Depreciation of fixed assets, except on those related to exploration and production activities, is computed on the revalued cost, using the straight-line method by applying depreciation rates that are based on the estimated remaining useful lives of the fixed assets.

Fixed assets are written down whenever events and changes in circumstances indicate that the carrying amount may not be recoverable. Eni calculates the writedown as the difference between the expected accumulated discounted cash flow and the book value of the asset.

When the circumstances causing impairment cease to exist, Eni reverses previously recorded impairment charges net of depreciation.

97

##### Table of Contents

Renewals and improvements which extend asset lives are capitalized; maintenance and ordinary repairs are expended as incurred.

Intangible assets

Intangible assets are stated at cost, including interest on debt incurred in connection with specific projects as indicated previously for fixed assets.

Goodwill is recorded as an asset when acquired for consideration and is amortized at constant rates in the periods of use, provided it is no longer than 20 years from the year of recording.

Other intangible assets, except for those related to exploration and production activities, are amortized over the period of expected benefit. Intangibles are written down whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Eni calculates the writedowns as the difference between the expected accumulated discounted cash flow and the book value of the intangible assets. When the circumstances causing impairment cease to exist, Eni reverses previously recorded impairment charges net of amortization. However, goodwill and capitalized organizational costs are not revalued.

Exploration and production activities

Acquisition of mineral rights

Costs associated with the acquisition of mineral rights, including reserves purchased in connection with such acquisition, are capitalized. Mineral rights can also include exploration permits, among other items. Mineral rights are amortized on a straight-line basis over the expected period of benefit. Capitalized costs associated with proved reserves are amortized on a Unit-of-Production (UOP) basis, while capitalized costs related to all other reserves are not amortized until classified as proved. Capitalized costs related to abandon drilling programs are expensed.

Exploration

Costs associated with exploratory activities for oil and gas producing properties incurred to obtain information in order to characterize fields (such as acquisition of seismic data from third parties, test wells and geophysical surveys) are recorded as intangible assets and amortized in full in the period incurred (i.e. expended as incurred for financial reporting purposes).

Development

Costs incurred in development activities (acquisition of concessions, drilling of wells and their completion before production, as well as plants necessary for production, etc.) are capitalized and amortized on a UOP basis. Costs related to unsuccessful developmental wells are expensed immediately as loss on disposal.

Writedowns and revaluations of development costs are made on the same basis as those for fixed assets.

Production

Production costs such as ordinary maintenance of wells, extraction, transport, etc. are expended as incurred.

Abandonment

Eni regularly accrues costs expected to be incurred with respect to eventual well abandonment, including costs associated with site restoration, on a unit of production basis.

Reserve for employee termination indemnities and other employee benefits

Eni’s employees are eligible, immediately upon termination, for severance pay pursuant to Italian law. Eni accrues a reserve for such employee termination liabilities over the period of employment. The amount accrued at each balance sheet date reflects the aggregate liability for all eligible employees if terminated, net of applicable advances.

In addition, Eni makes contributions to certain employee associations that provide medical and various other employee benefits to current employees. These plans are not administered by Eni and contributions are determined in accordance

98

##### Table of Contents

with the provisions of negotiated contracts with trade unions. Eni expenses the contributions to the associations in the periods in which they are made. Such amounts are not significant.

Eni’s pension obligations relate only to operations outside Italy and are not significant.

Treasury shares

Treasury shares are recorded at cost written-down for impairments in value as a reduction of shareholders’ equity. When the reasons for the impairment cease to exist, treasury shares can be revalued up to the original cost basis.

Recognition of revenues and costs

Revenues from sales of products are recognized upon transfer of title. Revenues from services are recognized when the services have been provided. In particular, revenues are recognized: for natural gas when the natural gas comes out of Eni’s transmission or distribution network and is delivered to the consumer, for liquid hydrocarbon when it is delivered to the plants (except for some contractual regulations). Revenues relating to long-term construction contracts are recognized using the percentage-of-completion method.

Costs are recognized when the related goods and services sold, consumed or allocated, or when their future useful lives cannot be determined.

Eni is party to certain Production Sharing Agreements whereby taxes are settled by state-owned entities in the name and on behalf of Eni out of reserves produced. The company records such income taxes owed by Eni but paid on its behalf in revenues and income tax expense.

Income taxes

Deferred tax assets or liabilities are recognized for differences between the financial reporting and tax bases of assets and liabilities at each reporting period. Deferred tax liabilities are not recognized if ultimate payment is not deemed probable. Deferred tax assets are recognized when there is a reasonable expectation of their realization. Deferred tax liabilities are recorded in the “Non-current income tax liabilities” account, while deferred tax assets are recorded in “Other” (non-current assets). Deferred tax assets are offset against deferred tax liabilities if they relate to the same tax paying entity.

Derivatives

With respect to interest rate, foreign exchange and price risks, Eni enters into derivative transactions to hedge specific transactions as well as net interest rate and foreign currency positions. See Note 24 for a description of Eni’s overall strategy and description of financial instruments utilized to mitigate market risk.

The interest differentials to be received or paid on interest rate swaps, as well as interest differentials on interest rate collars, are charged to the income statement on an accrual basis. The interest differentials on forward rate agreements are recognized at the date of settlement of the contract and charged to the income statement on an accrual basis over the period hedged. Such interest rate differentials are recorded in “Accrued interest and other current assets” or “Accrued expenses and other” (current liabilities) as applicable until recognized in the income statement as “Financial expense and exchange differences net”.

Foreign exchange hedge derivatives (swaps, futures, options, etc.) are valued at the spot rate at year-end and the related gains and losses are recorded in income as exchange gain and loss. Premiums or discounts are accrued over the life of the contract and classified as exchange differences. With reference to options, the premiums paid are recorded as “Marketable securities” or “Other assets”, depending on the maturity of the contract.

The gains on price risk hedge derivatives (interest rate swaps, futures and swaps) are recorded in income to the extent of writedowns of hedged assets; losses are recorded in income if necessary to adjust the hedged assets to the value attributed to it by the derivative when they are incurred, consistent with the evaluation of the hedged assets. The gains and losses are classified consistently with the classification of the sale of the hedged asset.

Environmental expenditures

Environmental expenditures are made in order to prevent, reduce, repair or control the environmental impact of production activities. Environmental expenditures that improve or extend the useful lives and increase the capacity or safety of fixed assets are capitalized in the appropriate fixed asset accounts. Ongoing environmental compliance costs are expended as

99

##### Table of Contents

incurred. Reserves for environmental contingencies are established when it becomes probable or certain that a liability has been incurred and the amount can be reasonably estimated.

Restructuring costs

The costs of redundancy incentives are accrued when a workforce reduction program is defined and the conditions precedent for its implementation have been satisfied. Such charges are recorded as extraordinary items. Restructuring charges also include the costs of closures of facilities and asset impairments.

Research and development costs

Research and development costs are generally expensed as incurred.

For the years ended December 31, 2000, 2001 and 2002, total research and development costs were euro 234 million, euro 203 million and euro 175 million, respectively.

Statements of cash flows

The cash flow statements are prepared in accordance with International Accounting Standards, using the indirect method. Unless otherwise indicated, all monetary amounts in the financial statements and in these notes are presented in millions of euro or millions of U.S. dollars, except share, per share, ADS and per ADS data.

Reclassification of financial statements

Starting from 2002 the item “Cash” has been renamed “Cash and cash equivalent”, and includes cash and, in addition, marketable securities and current financing receivables with original maturities of less than 90 days. Accordingly, marketable securities and current financing receivables for the year 2001 have been reclassified for euro 11 and 74 million respectively.

3 Translation of euro amounts into U.S. dollar amounts

The financial statements are stated in euro. The translations of euro amounts into U.S. dollars are included solely for the convenience of the reader, using the noon buying rate certified for customs purposes by the Federal Reserve Bank of New York as of December 31, 2002, which was 1.0485 USD to euro 1.00. The convenience translations should not be construed as representations that the euro amounts have been, could have been, or could in the future be, converted into U.S. dollars at this or any other rate of exchange.

An analysis of the allowance for doubtful accounts (euro 875 million) is as follows:

(million €) |  | Dec. 31, 2001 |  | Additions |  | Reductions |  | changes |  | Dec. 31, 2002

Other changes of euro 407 million depends primarily on the merger of Bormia SpA (in liquidation) (euro 203 million) and the merger of Pertusola Sud SpA (in liquidation) and Mineraria Campiano SpA (in liquidation) in Singea SpA (in liquidation), now mergered in EniChem SpA (euro 177 million).

“Trade” receivables of euro 9,090 decrease of euro 149 million. This decrease is primarily due to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 228 million).

“Financing” receivables of euro 2,626 million include loans made for operating purposes for euro 2,624 million (euro 2,859 million at December 31, 2001 included only loans made for operating purposes). Loans made to affiliates are granted primarily by the Exploration & Production segment (euro 686 million) and Gas & Power segment (euro 1,744 million).

The euro 233 million decrease is primarily due to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 424 million) and the inclusion in consolidation of Polimeri Europa SpA (euro 216 million); this decrease is offset in part by a loan made to an affiliated company, EnBW Eni Verwaltungsgesellschaft mbH, for the acquisition of Gasversorgung Suddeutschland GmbH (euro 264 million).

Repayment of such receivables of euro 38 million (euro 267 million at December 31, 2001) is contingent upon the outcome of financed activities, while a portion of the loans may be converted into capital.

“Other” receivables of euro 4,314 consist of the following:

Other receivables |  |  | 865 |  |  |  | 777 |
|  |  | 4,234 |  |  |  | 4,314 |

Accounts receivable from Italian tax authorities for tax credits do not include tax credits generated in 1988, and applicable interest, for which Eni’s companies have filed formal appeals (mainly Eni SpA for euro 104 million and euro 107 million at December 31, 2001 and 2002, respectively). These receivables have been written-off pending the final outcome of the appeal. The decrease in income tax credits of euro 462 million depends essentially on the release of receivables related to taxes due.

The interest rate applicable to tax credits has been 2.5% for each six month period from January 1, 1997.

Approximately 45% of Eni’s non-current receivables at December 31, 2002 were denominated in currencies other than the euro (53% at December 31, 2000). Eni did not have any significant concentration of credit risk as of December 31, 2001 and 2002.

Oil and petroleum products inventories of euro 595 million represent certain minimum quantities (“compulsory stock”) required by law (euro 548 million at December 31, 2001) and natural gas inventories of euro 39 million represent strategic stock (the same amount at December 31, 2001), while natural gas inventories valued at euro 571 million are used to satisfy peak demand (euro 401 million at December 31, 2001).

The excess of market value over the book value of crude oil, petroleum products and purchased natural gas at year-end is euro 1,375 million (euro 781 million at December 31, 2001). The euro 594 million increase is primarily due to the recovery in international oil prices.

The increase of 554,550 shares nominal value 1 euro results from the issue of shares subscribed under the stock grant plan.

Reserves

The legal reserve of Eni SpA represents earnings restricted from the payment of dividends pursuant to the Italian Civil Code (the “Civil Code”). Under the Civil Code, with respect to income of any year, an amount equal to 5% of the net income of Eni SpA, as recorded in Eni SpA’s statutory financial statements for such year, must be set aside until the cumulative legal reserve is equal to one-fifth of the nominal value of Eni SpA’s issued and outstanding share capital. Such dividend restriction also applies to each Italian subsidiary of Eni.

Reserves include amounts received from the Ministry of Economic and Finance to reimburse Eni SpA for principal and interest payments on loans obtained and bonds issued in prior years, which under laws 730/83, 749/85 and 41/86, were obligations of the Government.

The “Reserve for the issue of shares in accordance with art. 2349 of the Italian Civil Code” contains earnings destined to increase share capital under the stock option plan. On December 31, 2002 the number of shares to assign for no consideration is 3,559,850 shares nominal value 1 euro (3,079,500 shares at December 31, 2001).

(1) |  | At December 31, 2001 and 2002, respectively the Ministry of Economy and Finance results the sole shareholder with more than 2% of the share capital.

Income taxes due relate to Irpeg (National income tax) for euro 1,156 million and Irap (Regional income tax) for euro 252 million and foreign income taxes of euro 43 million.

The effective tax rate is 37.5% compared with a statutory tax rate of 42.1%, calculated by applying a 36% tax rate (Irpeg) to income before taxes and 4.25% tax rate (Irap) to the net value of production as provided for by Italian laws.

The difference between the statutory and effective tax rate is due to the following factors:

(%) |  | 2000 |  | 2001 |  | 2002
Statutory tax rate |  |  | 42.7 |  |  |  | 40.9 |  |  |  | 42.1 |

Permanent timing differences of year 2001 concern mainly the gain recorded in the consolidated financial statements due to the public offering of 40.24% of the share capital of Snam Rete Gas SpA (7.2%).

23 Earnings per share

Earnings per share for the year 2000 and have been restated to reflect the conversion of the share capital from Italian lire to euro.

Earnings per share is calculated by dividing net income by the weighted-average number of shares issued and outstanding during the year, excluding treasury shares.

In order to compare earnings per share in the two years presented, the number of shares issued through stock grants made in 2001 and 2002 has been added to the number of shares outstanding in previous years. Based on this criterion, the number of shares outstanding was 3,995,126,901, 3,910,798,299 and 3,825,837,521, in the accounting year 2000, 2001 and 2002 respectively.

The dilutive effect of potential ordinary shares when converted into ordinary shares on earnings per share is not material. At present, only shares assigned for no consideration are considered and the stock options to be exercised have a book value (euro 15.216) higher than the stock market of at December 31, 2002 (euro 14.509).

24 Commitments and contingencies

Derivative financial instruments

Eni operates internationally in the oil and natural gas, electricity generation, petrochemicals and oilfield services and engineering industries and is subject to exposure to market risks from changes in interest rates, foreign exchange rates and commodity prices.

Derivative financial instruments are utilized by Eni to reduce these risks, as explained below.

Eni’s treasury activities are managed primarily by two captive finance companies operating in the Italian and international financial markets. Eni’s operating subsidiaries are required to reduce foreign exchange rate risk to a minimum level by coordinating their operations with such finance companies.

Eni SpA’s Board of Directors has defined a policy that requires the Treasury Department of Eni SpA to determine the maximum level of foreign exchange rate and interest rate risks that can be assumed by Eni’s finance companies. Such policy also defines the eligible counterparties in derivative transactions. As far as interest rate and foreign exchange rate risks are concerned, the calculation and measurement techniques followed by Eni’s finance companies are in accordance with established banking standards (such standards are established by the Basel Committee). However, the tolerable level of risk adopted by such companies is more conservative than that defined by the Basel Committee: Eni SpA’s Treasury Department is responsible for monitoring compliance with Eni’s policy, as well as the correlation between the indicators adopted for measuring of the tolerable risk level, the portfolio of financial instruments and market conditions.

Eni does not enter into derivative transactions on a speculative basis.

(a) Notional amounts and credit exposures of derivatives

The notional value of a derivative is the contractual amount on the basis of which the differentials are exchanged; this amount can be expressed either on a value basis or on a physical quantities basis (such as barrels, tonnes, etc.). The amounts expressed in foreign currency are converted into euro applying the exchange rate at year-end.

The notional amounts of derivatives summarized in the sections that follow do not represent amounts exchanged by the parties and, thus, are not a measure of the credit exposure of Eni. The amounts exchanged are calculated on the basis of the notional amounts and the other terms of the derivatives, which relate to interest rates, exchange rates and commodity prices. Therefore, the credit exposure of interest rate, foreign exchange and commodity contracts is represented by the fair value of contracts with a positive fair value at year-end, reduced by the effects of master netting agreements. Eni SpA’s Board of Directors has approved policies which provide guidelines related to the criteria of eligible counterparties in derivative transactions and permissible financing investments, including purchases of securities. Although Eni is exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments, it does not expect any counterparties to fail to meet their obligations given the high credit standings of such counterparties.

(b) Interest rate risk management

Eni enters into various types of interest rate contracts in managing its interest rate risk, as indicated in the following table:

|  | Dec. 31, 2001 |  | Dec. 31, 2002
(million €) |  | Notional amount |  | Notional amount
Interest rate swaps |  |  | 3,208 |  |  |  | 5,206 |
Forward rate agreement |  |  | 168 |  |  |  | 220 |
Interest rate collars |  |  | 134 |  |  |  | 129 |
|  |  | 3,510 |  |  |  | 5,555 |

Eni enters into interest rate derivatives, particularly interest rate swaps, to alter interest rate exposures arising from mismatches between assets and liabilities, to lower funding costs and to diversify sources of funding. Under interest rate swaps, Eni agrees with other parties to exchange, at specified intervals, the difference between interest amounts calculated by reference to an agreed notional principal amount and agreed fixed or floating interest rates. Euro 1,998 million increase of IRS is primarily due to Enifin’s transactions in order to hedge financial payables granted to Snam Rete Gas SpA and to hedge financial receivables and payables of Eni Coordination Center SA.

The following table indicates the types of interest rate swaps used and their weighted-average interest rates and maturities. Average variable rates are based on rates at year-end and may change significantly, affecting future cash flows.

The comparison between weighted-average receive rate and weighted-average pay rate does not represent the result of derivatives: such result is calculated on the basis of the underlying hedged operation.

|  | Dec. 31, 2001 |  | Dec. 31, 2002
Receive-fixed/Pay-floating swaps-notional amount (million euro) |  |  | 1,202 |  |  |  | 1,201 |
— weighted average receive rate |  |  | 6.99 | % |  |  | 6.42 | %
— weighted average pay rate |  |  | 3.50 | % |  |  | 2.77 | %
— weighted average maturity (years) |  |  | 3.93 |  |  |  | 3.74 |
Receive-floating/Pay-floating swaps-notional amount (million euro) |  |  | 813 |  |  |  | 1,802 |
— weighted average receive rate |  |  | 4.17 | % |  |  | 3.32 | %
— weighted average pay rate |  |  | 4.21 | % |  |  | 3.95 | %
— weighted average maturity (years) |  |  | 4.13 |  |  |  | 4.49 |
Pay-fixed/Receive-floating swaps-notional amount (million euro) |  |  | 1,193 |  |  |  | 2,203 |
— weighted average pay rate |  |  | 4.84 | % |  |  | 4.73 | %
— weighted average receive rate |  |  | 3.31 | % |  |  | 2.43 | %
— weighted average maturity (years) |  |  | 2.97 |  |  |  | 6.15 |

Forward rate agreements are generally used by Eni to offset changes in the rates of short and long-term floating-rate debt. Forward rate agreements settle in cash at a specified future date based on the differential between agreed interest rates applied to a notional amount. Forward contracts at year-end are related to contracts whereby Eni pays a fixed rate for euro 220 million (received a fix rate for euro 5 million and paid a fix rate for euro 163 million at December 31, 2001). These contracts have terms of less than one year. Gains and losses estimated at December 31, 2002, are not material.

Eni also uses interest rate collars to manage its interest rate risk. An interest rate collar is a combination of options that enable a predetermined interest rate band to be locked in. Eni also uses zero-cost collars that do not require payment of an option premium. Interest rate collar contracts at year-end have terms of up to five years.

(c) Foreign exchange risk management

Eni enters into various types of foreign exchange contracts in managing its foreign exchange risk, as indicated in the following table:

|  | Dec. 31, 2001 |  | Dec. 31, 2002
(million €) |  | Notional amount |  | Notional amount
Forward exchange contracts |  |  | 5,172 |  |  |  | 7,611 |
Purchased options |  |  | 538 |  |  |  | 348 |
|  |  | 5,710 |  |  |  | 7,959 |

Eni uses forward exchange contracts primarily to hedge existing receivables and payables, including deposits and borrowings denominated in foreign currencies. Some of the contracts involve the exchange of currencies other than the local currency, according to the needs of foreign consolidated subsidiaries. Both buy and sell amounts of such contracts are indicated at the notional value. The term of forward exchange contracts is normally one year. Euro 2,439 million increase of forward exchange contracts is primarily due to Enifin’s SpA transactions in order to hedge financial short-term payables (expressed in pound sterling and changed in U.S. dollar) of Eni Coordination Center SA.

Eni also uses currency options to hedge expenses denominated in foreign currencies. Currency options, purchased in the over-the-counter market for a premium, provide Eni with the right to buy or sell an agreed amount of currency at a specified exchange rate at the end of a specified period, normally two years.

The table below summarizes, by major currency, the contractual amounts of Eni’s forward exchange and option contracts.

|  | Dec. 31, 2001 |  | Dec. 31, 2002
(million €) |  | Buy |  | Sell |  | Buy |  | Sell
U.S. dollar |  |  | 1,429 |  |  |  | 2,480 |  |  |  | 1,290 |  |  |  | 3,515 |

|  |  | 2,449 |  |  |  | 3,261 |  |  |  | 3,850 |  |  |  | 4,109 |

(d) Commodity price risk management

Exchange traded crude oil and petroleum product futures contracts and over-the-counter market swaps are primarily used by the Refining & Marketing segments to minimize the commodity price volatility. Futures contracts have little credit risk because they take place in regulated markets. Swap agreements do not contain margin requirements and are subject to the creditworthiness of counterparties, which are principally major financial institutions. At December 31, 2001 and 2002 the notional amounts of open contracts are not material.

(e) Sales of government bonds

Eni sold Italian Government bonds to investors, primarily employees, and simultaneously entered into interest rate swaps with such investors wherein Eni receives the rate of interest on such Italian Government bonds and pays a floating rate of

121

##### Table of Contents

interest linked to Euribor (Europe Interbank Offered Rate). Such investors may sell their securities back to Eni at any time for par value plus related interest with the simultaneous cancellation of the related swaps. Eni also entered into an interest rate swap with a financial institution wherein it receives a floating rate which is considered more favorable for its floating rate commitment to its investors. At December 31, 2001 and 2002, euro 150 million and euro 178 million, respectively, worth of such securities remained in the hands of employees. For accounting purposes, this transaction was treated as a sale of the bonds with gains recognized in current income.

Guarantees

Guarantees have been given by Eni to third parties. At December 31, 2000 and 2001, these guarantees were as follows:

|  | At Dec. 31, 2001 |  | At Dec. 31, 2002

Eni believes such matters will not have a material adverse effect on its consolidated financial statements.

Legal proceedings

Eni is a party to a number of civil actions and administrative proceedings arising in the ordinary course of business.

Based on information available to date, and taking account of the existing contingencies, Eni believes that the foregoing will not have a material adverse effect on Eni’s consolidated financial statements.

The following is a summary of significant legal matters in which Eni is involved.

Judicial or Arbitration Proceedings

In 1991, Agrifactoring SpA commenced proceedings against Serfactoring SpA a company 49% owned by the former Serfi SpA now Sofid SpA, which is controlled by Eni SpA. The claim relates to euro 182 million of receivables for fertilizer sales (plus interest and compensation for inflation), originally owed by Federconsorzi to EniChem Agricoltura SpA (later Agricoltura SpA (in liquidation) now merged in EniChem SpA) and Terni Industrie Chimiche SpA (merged in Agricoltura SpA (in liquidation) that has been merged in EniChem SpA). Such receivables were transferred by Agricoltura and Terni to Serfactoring, which appointed Agrifactoring as its agent to collect payments. Agrifactoring guaranteed to pay the amount of such receivables to Serfactoring, regardless of whether or not it received payment. Following payment by Agrifactoring to Serfactoring, Agrifactoring was placed in liquidation and the liquidator of Agrifactoring commenced proceedings in 1991 against Serfactoring to recover such payments (equal to euro 182 million) made to Serfactoring based on the claim that the foregoing guarantee became invalid when Federconsorzi was itself placed in liquidation. Agricoltura and Terni brought counterclaims against Agrifactoring for damages amounting to euro 97 million relating to acts carried out by Agrifactoring SpA as agent. The amount of these counterclaims has subsequently been reduced to euro 46 million following

partial payment of the original receivables by the liquidator of Federconsorzi and various setoffs. In January 2000, the technical opinion requested by Agrifactoring was completed. According to this opinion, the balance of the account between Agrifactoring and Federconsorzi, on which Agrifactoring is claiming payment of euro 182 million, amounts to approximately euro 40 million. These proceedings, which have all been joined, are in awaiting judgment.

In 1992, Eni SpA and EniChem SpA initiated an arbitration proceeding against Montedison SpA and its subsidiaries in relation to guarantees given by them in connection with the formation of Enimont SpA. On March 6, 2003 Eni has reached an agreement with Montedison, now merged in Edison, that close the arbitration proceeding. Additional information about the transaction is included in “Other Information — Subsequent events” of the Reports of the Directors.

Tax Proceedings

Agip SpA (now merged in Eni SpA) received four formal assessments from the Italian tax authorities that claimed that its income in 1989, 1990, 1991 and 1992 had been understated for income tax purposes. These assessments concern an alleged global understated amount for euro 196 million, determined by marking downward and upward adjustments to the prices of certain petroleum products that Agip sold to or bought from other Eni companies. All these claims were judged as unfounded by the Provincial Tax Commission of Milan. The appeal of the tax authorities against the first three assessments were rejected by the Regional Tax Commission of Milan. The appeal of the tax authorities against the fourth decision, related to 1992, has not yet been discussed. In December 2000 the tax authorities notified Eni SpA of formal assessment concerning income understatement for 1994, for an improper use of loss carryforwards for euro 20 million. The Provincial Tax Commission of Milan accepted Eni’s claim with decision issued on May 7, 2001.On June 26, 2002 Tax authorities has proposed appeal to the Regional Tax Commission.

With a decree dated December 6, 2000 the Lombardia Region decided that natural gas used for electricity generation is subject to an additional regional excise tax in relation to which Snam SpA (now merged in Eni SpA) will substitute the tax authorities in its collection from customers. Given interpretive uncertainties, the same decree provides the terms within which distributing companies are expected to pay this excise tax without paying any penalty. Snam SpA and the other distributing companies of Eni believe that natural gas used for electricity generation is not subject to this additional excise tax and therefore appealed this decree against the jurisdictional bodies. With respect to this matter an official interpretation was requested from the Ministry of Economy and finance. With decision of May 29, 2001 the Ministry confirmed that the additional excise tax cannot be applied. The Region decided not to revoke its decree and Snam took appropriate legal action. On the basis of action carried out by Snam, the Council of State decided on March 18, 2002 that payment of the additional excise tax, Snam will challenge this request in Court. At a later date the Lombardia Region decided with regional law 27/2001 that no additional tax is due from January 1, 2002 onwards, but still requested the payment of the additional taxes due before that date.

Environment

In 1992, the Minister of Environment filed an action against EniChem SpA and other parties to recover between euro 135 million and euro 870 million in damages relating to the discharge of effluents by the Mantua plant. This plant was owned by a former subsidiary of Montedison SpA that was conferred to Enimont SpA in connection with the formation of the Enimont joint venture. In September 1999, the State attorney requested that all the parties be condemned by the Court of Brescia to pay compensatory damages resulting from the proceeding of not less than euro 135 million.

An action was started in 1997 concerning the criminal charges brought by the Venice public prosecutor against 28 persons, including 12 former and current managers of subsidiaries of Eni2, for alleged mismanagement of the Porto Marghera plant starting in the 1970s and for the alleged pollution and health damage resulting therefrom. In most cases such charges relate to a period in time when the plant was managed by companies not owned by Eni. On November 2, 2001 the Court of Venice acquitted all defendants. On May 3, 2002 the judgment was deposited. The State attorney has proposed appeal, but the date for the debate is not yet fixed.

In 1999, the public prosecutor of Gela started an investigation against a former manager of the refinery in order to ascertain eventual soil and sea pollution caused by the discharge of effluents by the refinery On November 2002, “Italia Nostra” and the association “Amici della Terra” constituted themselves as civil part and requested the payment of compensatory damage from AgipPetroli (now merged in Eni SpA) for a total of euro 15,050 million. The delay of the preliminary stage of the proceeding was rejected by the judge for preliminary investigations because it was requested by the public prosecutor too late; inquiries remain admitted as evidence.

In 2000, the public prosecutor of Brindisi started a criminal action against 68 persons employees or former employees of various companies that owned and managed plants for the manufacture of dichloroethane, vinyl chloride monomer and

vinyl polychloride from the early 1960s to date. Among these persons 20 are former employees or managers of EniChem SpA that managed these plants from 1983 to 1993.The preliminary stage of the proceeding is closed with a request of dismissal for EniChem’s employees. The judge for preliminary investigations still has to decide about the dismissal.

In 2000, the public prosecutor of Gela started an investigation on prohibited emissions from AgipPetroli SpA’s refinery (now merged in Eni SpA) (as per art. 674 of the Criminal Code), which are purported to have had negative effects on the health of a number of citizens of Gela, and on AgipPetroli’s lack of declaration of such emissions in violation of Presidential Decree No. 203 of 1998. The investigation brought an action against some former managers of the refinery for events registered from 1997. The Municipality of Gela, the Province of Caltanissetta and others will act as civil party and requested the payment of compensatory damage from Agip Petroli for a total of euro 878 million.

The proceeding related to the environmental tax introduced by the Regional law No. 2 of March 26 is included in the “Operating Review — Gas & Power — Quadro normativo” of the Reports of the Directors, that is considered an integral part of the notes to the Consolidated Financial Statement.

On January 16, 2003 the court of Siracusa granted the detention for 7 employees of Enichem SpA and Polimeri Europa SpA and house arrest for an other 10 employees of the same companies. They are accused of criminal association in the mismanagement relating to the production, disposal and treatment of liquid and solid waste materials, obtaining an illicit income in violation Decree No. 417/1999 (Ronchi Decree ) of the Ministry of Environment and the article 416 of the penal code. On September 2001 the Public Prosecutor of Siracusa started an inquire relating to investigate the mismanagement of the (liquid and solid) waste materials in Enichem’s plant of Priolo, the inquiry involves also the chloro soda plant. On February 6, 2003 the Court of Reviews decided the transformation of the imprisonments in house arrest and cancelled granted a detetion for other employees inquired.

Antitrust, EU Proceedings, and actions of the Authority for Electricity and Gas

In March 1999, the Antitrust Authority concluded its investigation and: (i) verified that Snam SpA (now merged in Eni SpA) abused its dominant position in the market for the transportation and distribution of natural gas; (ii) fined Snam SpA euro 2 million; (iii) ordered a review of these practices relating to such abuses. Snam believes it has complied with existing legislation and appealed the decision with the Regional Administrative Court of Lazio. On May 26, 1999 by according that these decisions are against law No. 9/1991 and the European Directive 98/30/CE, this Court has granted the suspension of the decision. The Antitrust Authority did not appeal this decision. The definition of the dispute is still pending.

The Antitrust Authority’s decision presented to Snam SpA (now merged in Eni SpA) on October 30, 2001, on suggestion of Blugas SpA whose request for access to the Italian natural gas network is included in the “Operating Review — Gas & Power — regulatory framework” of the Reports of the Directors, that is considered an integral part of the notes to the Consolidated Financial Statement.

With a decision presented on June 5, 2001 the Antitrust Authority started an inquiry against AgipPetroli SpA, Atriplex SpA and other companies for alleged limitations to competition within the tenders offered by public transportation companies in the urban areas of Naples, Turin and Milan for the supply of gasoil for automotive use in the period 1996-2000. This proceeding intends to ascertain if the alleged agreements could be the expression of a more general arrangement among companies for dividing between them the mentioned fuel supplies. The Authority has postponed the closing date of the proceeding from October 11, 2002 to February 24, 2003. On December 10, 2002 parties had the last hearing. On March 4, 2003 it’s been notified the Authority’s decision, that has verified violations for all companies involved and has fined AgipPetroli and Atriplex euro 118 thousand. Eni is valuating the possibility to appeal the decision to the Regional Administrative Court of Lazio.

Environmental Regulations

Together with other companies in the industries in which it operates, Eni is subject to numerous EU, national, regional and local environmental laws and regulations concerning its oil and gas operations, products and other activities, including legislation that implements international conventions or protocols. In particular, these laws and regulations require the acquisition of a permit before drilling for hydrocarbons may commence, restrict the types, quantities and concentration of various substances that can be released into the environment in connection with exploration, drilling and production activities, limit or prohibit drilling activities on certain protected areas, and impose criminal or civil liabilities for pollution resulting from oil, natural gas, refining and petrochemical operations. These laws and regulations may also restrict air emission and discharges to surface and subsurface water resulting from the operation of natural gas processing plants, petrochemicals plants, refineries, pipeline systems and other facilities that Eni owns. In addition, Eni’s operations are subject to laws and regulations relating to the generation, handling, transportation, storage, disposal and treatment of waste materials. Environmental laws and regulations have a substantial impact on Eni’s operations. Some risk of environmental

costs and liabilities is inherent in particular operations and products of Eni, as it is with other companies engaged in similar businesses, and there can be no assurance that material costs and liabilities will not be incurred. Although Eni, considering the actions already taken, the insurance policies to cover environmental risks and the provision for risks accrued, does not currently expect any material adverse effect upon its consolidated financial statements as a result of its compliance with such laws and regulations, there can be no assurance that this will be the case due to: (i) the possibility of as yet unknown contamination; (ii) the results of the on-going characterizations and the other possible effects of decree No. 471/99 of the Ministry of Environment; (iii) the possible effect of future environmental legislation and rules; (iv) the effect of possible technological changes relating to future remediation; (v) the possibility of litigation and the difficulty of determining Eni’s liability, if any, as against other potentially responsible parties with respect to such litigation and the possible insurance recoveries.

26 Fair value of financial instruments

In the normal course of its business, Eni utilizes various types of financial instruments. These instruments include recorded assets and liabilities, as well as items that principally involve off-balance sheet risk. Information about the fair value of Eni’s financial instruments is presented below.

• |  | Marketable securities: the fair values of marketable securities are based upon market value.
• |  | Non-current investments carried at cost: such investments are not publicly traded and do not have quoted market prices. An estimate of fair value has not been made because the amount of the investment is not significant and the estimation of fair value would require incurring excessive costs.
• |  | Current investments: such investments are publicly traded and their fair value is represented by their market price.
• |  | Non-current receivables: the fair values of non-current receivables are estimated based on the discounted value of future cash flows expected to be paid, considering rates of interest which Eni could earn on similar credit. The differences between the carrying and market values of non-current receivables at December 31, 2001 and 2002, excluding tax credits with Italian tax authorities, were not significant and are not included below. In relation to tax credits the interest rate (2.5% on a six-month basis) is aligned with the average market rate trend.

##### Table of Contents

• |  | Current receivables: the fair values of current receivables are not included below because they are approximated by their carrying values.
• |  | Bonds payable, current portion of long-term debt and long-term debt: the fair values of bonds payable and long-term debt, including current maturities, are based on discounted cash flow analyses.
• |  | Short-term debt: the carrying value of short-term debt approximates fair value because of the short period of time between the origination and maturity of the borrowings.

Non-current payables: the fair values of non-current payables are estimated based on the discounted value of future cash flows. The differences between the carrying and market values of non-current payables at December 31, 2000 and 2001, were not significant and are not included below.

|  | Dec. 31, 2001 |  | Dec. 31, 2002
|  | Carrying |  | Fair |  | Carrying |  | Fair
(million €) |  | Value |  | Value |  | Value |  | Value
Marketable securities and current investments |  |  | 1,709 |  |  |  | 1,736 |  |  |  | 1,530 |  |  |  | 1,548 |
Bonds and long-term debt, including current maturities(1) |  |  | 7,317 |  |  |  | 7,641 |  |  |  | 7,530 |  |  |  | 8,002 |

(1) |  | The carrying value is increased by the market value of the acquired interest rate financial debts which are recorded under “Accrued expenses and deferred income” of balance sheets liabilities and it is decreased by implicit interest under “Accrued expenses and deferred income” of balance sheets assets.

• |  | Derivative financial instruments: the fair value of derivatives generally reflects the estimated amounts that Eni would pay or receive to terminate the contracts at the reporting date, thereby taking into account the current unrealized gains or losses of open contracts. Dealer quotes or appropriate pricing models have been used to estimate the fair value for Eni’s derivatives. The carrying value, compared with the fair value, represents the amount of interest rate and exchange rate differentials recognized but not yet paid at year-end. For foreign exchange derivatives related to monetary assets and liabilities, the carrying value also represents the adjustment using current exchange rates at year-end. The difference between carrying value and fair value is therefore not significant.

28 Summary of significant differences between Italian accounting principles and U.S. GAAP

Eni’s financial statements have been prepared in accordance with Italian GAAP, which differ in certain respects from U.S. GAAP. A description of the significant differences and their effects on net income and shareholders’ equity is set forth in the following notes.

Consolidation policy

Under Italian GAAP the consolidated financial statements include the statutory accounts of Eni SpA and all Italian and foreign companies controlled by Eni SpA, directly or indirectly, either by holding the majority of the voting rights or, in cases where Eni holds less than 50% of the voting rights, when it exercises control in shareholders’ meetings.

Under U.S. GAAP investments of less than 50% would be accounted for by applying the equity method. Saipem SpA and Societ Italiana per il Gas pA, including the subsidiaries of such entities which are controlled by Eni without holding the majority of voting rights, have been accounted for under the equity method for U.S. GAAP purposes.

Exploration & Production activities

Exploration costs

Under Italian GAAP, exploration costs, including successful exploratory wells, are recorded as intangible assets and are amortized in full in the period incurred (i.e. expensed as incurred for financial reporting purposes). Costs for the acquisition of exploration permits and for the extension of existing permits are capitalized and amortized over the expected period of benefit.

Under U.S. GAAP costs relating to exploratory wells and exploration permits are recorded as intangible assets until it is determined if commercial quantities of reserves have been discovered (“successful efforts method”). Costs related to unsuccessful wells are expensed immediately. Costs related to proved properties are amortized over proved reserves on the basis of unit of production. Other exploration costs are expensed when incurred.

Development costs

Under Italian GAAP, development costs of unsuccessful wells are expensed immediately. Development costs of successful wells are capitalized and amortized on the basis of units of production.

Under U.S. GAAP, development costs are accounted for using the successful efforts method described above.

Amortization of intangible assets

Under Italian GAAP, the goodwill is amortizated on a straight-line basis in the utilization period, over a maximum period of twenty years from the registration. Other intangible assets are amortizated systematically in relation with their residual useful life.

Under U.S. GAAP, the goodwill and the intangible assets with an indefinited useful life can not be amortized; these assets are subject to a yearly evaluation in order to define the relevant writedown if needed.

Valuation of assets and subsequent revaluation

Both Italian and U.S. GAAP require that assets which are impaired be written down to their fair value. However, under Italian GAAP, in order to determine whether an impairment exists the book value of an asset in question is compared to the sum of the discounted cash flows expected to be generated by such asset. If the sum of such discounted cash flows is less than the carrying value of the asset, an impairment exists.

U.S. GAAP requires the performance of the same analysis using undiscounted cash flows. To date there has been no significant difference between the applications of the two methods.

In addition, under Italian GAAP impairment charges are reversed when the situation giving rise to an impairment ceases to exist. Under U.S. GAAP reversals of impairment charges are not permitted.

Monetary revaluation of assets

Certain assets have been revalued at various times in accordance with various Italian laws. Under U.S. GAAP, such revaluations are not permitted. The adjustments provided in the following item c) include the effect of the recomputation of depreciation expense on a historical cost basis, as well as the elimination of these revaluations and the related accumulated depreciation.

Financing costs

Under Italian GAAP, direct financing costs for issuances of equity are capitalized by Eni in the account “Intangible assets — organizational and financing costs” and amortized over their economic useful lives, not to exceed 5 years.

Under U.S. GAAP, direct financing costs for issuances of equity are netted against related proceeds.

Treasury shares

Under Italian GAAP treasury shares, acquired as long-term investments, are recorded at cost adjusted for impairment. When the reasons for the impairment cease to exist, treasury shares are revalued.

Under U.S. GAAP all treasury shares are recorded at cost. At December 31, 2001 and 2002, such difference had no effect on net income and shareholders’ equity as determined under U.S. GAAP.

Marketable securities

Under Italian GAAP, marketable securities are carried at the lower of purchase cost or market value.

Under U.S. GAAP, the accounting for investments in marketable securities uses a fair market value methodology. Eni’s marketable securities would be classified as available-for-sale with changes in market value recorded as a component of shareholders’ equity.

Deferred tax assets liabilities

Under Italian GAAP deferred taxes are recorded if their recovery is reasonably certain. Taxes payable relating to certain potential distributions from shareholders’ equity or upon liquidation of a company are accrued only to the extent such distributions are planned. Any timing difference between purchase price and tax basis of an asset acquired does not result in the recording of an adjustment to the carrying value of such asset.

Under U.S. GAAP, deferred tax assets are recorded if their recovery is more likely than not. The potential taxes on equity reserves are considered deferred tax liabilities and are accrued accordingly. Deferred income taxes have not been provided on undistributed earnings of foreign subsidiaries as such earnings are expected to be permanently reinvested. In addition, under U.S. GAAP in situations where the purchase price of assets is not equal to the tax basis, deferred taxes must be provided for such differences and recorded as part of the acquisition.

The adjustments included below take into account the realizability of deferred tax assets, based on the more likely than not criteria rather than the certainty of their recovery, deferred taxes on undistributed earnings of subsidiaries and deferred taxes on acquired temporary differences. The adjustments also include the deferred tax effect of U.S. GAAP adjustments.

Depreciation

Until 1999, in accordance with Italian practice, depreciation of natural gas pipelines, natural gas distribution networks and related plant and machinery, was accounted for by applying rates on a straight-line basis established by Italian tax

authorities on the basis of technical studies conducted for homogeneous industries. Under U.S. GAAP, depreciation expense is recognized based on the estimated economic useful lives of the assets.

The publication of Legislative decree no. 164 of May 23, 2000, which imposed the separation of transmission and distribution activities from other natural gas activities and the criteria set for the determination of transport and distribution tariffs by the Authority for Gas & Power led companies operating in this segment to re-evaluate the useful lives of the assets. The useful lives calculated by Eni (40 years for pipelines and 50 for distribution networks) were confirmed by an independent appraisal and by the documents issued by the Authority. Therefore, from 2000 assets related to transmission and distribution activities are amortized base on these new useful lives, under Italian GAAP and U.S. GAAP.

Capitalized interest expense

Eni capitalizes interest expense only if certain conditions are met in the self-construction of assets.

Under U.S. GAAP, actual interest costs incurred to bring qualified assets to their intended use, that theoretically could have been avoided if the expenditures for the assets had not been made, must be capitalized.

The adjustment to U.S. GAAP for “Capitalized interest” represents the capitalization difference, based upon actual interest costs incurred during each period, as well as the subsequent depreciation effect of the additional capitalized interest.

Derivatives

Under Italian GAAP, derivative contracts are evaluated differently if they are used as hedging or as speculative instruments. Eni values derivatives that are used for hedging purposes, but that are not designated against specific transactions, according to the nature of the hedged assets. In particular, interest differences on derivatives hedging interest rates and premiums and discounts on exchange rate risk hedging contracts are recorded in the income statement in the year in which the hedged asset/liability is first recorded. Profits on derivative contracts on price risks are recorded in the income statement as offsetting the depreciation of the hedged asset. Losses are recorded when incurred. Derivative contracts used as speculative instruments are recorded at fair value and the related effects are recorded in the income statement.

U.S. GAAP generally requires that companies recognize all derivatives as either assets or liabilities on the balance sheet and that those instruments are measured fair value. Eni adopted SFAS 133 “Accounting for Derivative Instruments and Hedging Activities” for US reporting purposes on January 1, 2001. Eni uses derivative instruments to manage the risk of fluctuations in commodity prices, interest rates and foreign currencies (see note 24 for information regarding the instruments). U.S. GAAP now requires that derivative instruments that hedge the variability of expected cash flow, the fair value of an underlying, or foreign currencies related to a specific risk are designated as a cash flow hedge, fair value hedge, or foreign currency hedge, respectively. Changes in fair value of derivative instruments designated and effective as fair value and foreign currency hedges are recognized through earnings and changes in the fair value of cash flow hedges are recognized through equity as a component of other comprehensive income. For U.S. GAAP purposes relationships previously designated as cash flow hedges were no longer designated as such. Consequently, movements in the fair value of the derivative instruments have been recorded as adjustments to U.S. GAAP net income as reflected in the following item c).

Revenues

Italian GAAP classifies as revenues certain income and gains which would normally be considered as other income or reduction of expenses for purposes of U.S. GAAP. The effect of this differences on operating income is reflected in the following item c).

Extraordinary income and expense

Certain items recorded by Eni as extraordinary in the periods presented herein would not qualify as extraordinary under U.S. GAAP. Such items have been reclassified to the appropriate income statement captions as determined by U.S. GAAP and included in the determination of operating income by segment. In addition, under U.S. GAAP, extraordinary items are presented net of tax.

Sales of government bonds

Eni accounted for government bonds transferred primarily to employees at par value, with the repurchasing commitment at the same value, as sales of bonds, and recognized the related gains in current income. For U.S. GAAP purposes, the terms of these transactions would result in their treatment as financing transactions and consequently in a cash flow statement prepared under U.S. GAAP, these cash flows would be included in financing activities. Under this method, the bonds would remain as assets and the proceeds from the “sales” would be treated as obligations. Gains and losses from such sales are not significant.

Reclassification of inventory

Eni values crude oil, petroleum products and natural gas held as compulsory stock as inventories that are subject to lower of cost or market valuations annually.

Under U.S. GAAP, costs associated with compulsory crude oil, petroleum products and natural gas inventories are recorded, with fixed assets.

Stock compensation

Under Italian GAAP stock grants and options offered to employees for no consideration are recorded within the equity accounts when the shares are issued. In particular, stock grants made for no cash consideration are recorded at nominal value as a debit against the specific equity reserve, while shares issued after exercise of options are recorded as capital increase for the nominal value and as an increase in the special reserve for the difference between amounts paid for exercising the options and the nominal value of issued shares. No compensation expense is recorded.

Under U.S. GAAP stock grants and options are recorded as compensation expense for the excess of the market value over the exercise price of the stock on the measurement date. Such compensation expense is recorded over the period of benefit.

Eni has granted shares and options to employees for no consideration. The compensation costs related to these instruments have been included below.

Comprehensive income

U.S. GAAP requires the reporting and display of comprehensive income and its components in accordance with Statement of Financial Standard No. 130, “Reporting Comprehensive Income” (“SFAS 130”).

Components of other comprehensive income include variations in equity accounts not attributable to transactions already recorded in income or transactions with shareholders. The required information pursuant to SFAS 130 is presented in the reconciliation that follows. Deferred tax effects of exchange differences from the translation of functional currency financial statements have not been recorded as provided for by SFAS 109, which permits the exclusion of the calculation of taxes on equity reserves of foreign subsidiaries when the reserves are not expected to be released.

Gross operating margin

Gross operating margin consists of total revenues less operating expenses, excluding depreciation, amortization and writedowns. Under U.S. GAAP, gross operating margin would not be presented.

Earnings per share

Under Italian GAAP, basic earnings per share of prior periods is adjusted to include the weighted-average number of shares, issued and outstanding in the period for stock grant plans.

Under U.S. GAAP, basic earnings per share of prior periods is not adjusted to reflect future period stock issuances.

Goodwill as calculated under U.S. GAAP of euro 858 million is greater than goodwill as calculated under Italian GAAP by euro 557 million, due primarily to provisions for restructuring costs, which are expensed as incurred under Italian GAAP, and undiscounted deferred taxes, which are discounted under Italian GAAP. The difference in amortization expense resulting from difference in goodwill is included in the adjustment for “Successful efforts accounting” in the reconciliation in Note 30.

The effects of the Lasmo acquisition on the Company’s consolidated results of operations is not significant.

EXPLORATION & PRODUCTION: through Eni SpA’s Agip Division and subsidiaries, Eni engages in hydrocarbon exploration and production in Italy, North Africa (Algeria, Egypt, Libya, and Tunisia), West Africa (Angola, Congo, Gabon and Nigeria), the North Sea (Norway and the United Kingdom), Latin America (Venezuela and Ecuador), the former Soviet Union countries, mainly Kazakhstan, the United States (mainly in the Gulf of Mexico) and Asia (mainly Iran, Indonesia, Pakistan and China). In 2001 approximately 70% of oil production sold was supplied to Eni’s Refining & Marketing segment and approximately 40% of natural gas production sold was supplied to Eni’s Gas & Power segment.

Eni owns a storage system made up by a number of depleted fields used for the modulation of supply in accordance with seasonal swings in demand, (natural gas is stored in the summer and used in the winter), as strategic reserve to ensure supply and to support domestic production through mineral storage. Storage assets are owned by Stoccaggi Gas Italia (Eni 100%), a company constituted in accordance with the Legislative Decree n. 164 of May 23, 2000 that introduced laws for the liberalization of the Italian natural gas market.

GAS & POWER: Eni is engaged in the supply, transmission and sale of natural gas in Italy and outside Italy through Gas & Power Division, which was constituted by the incorporation of Snam SpA in Eni SpA in 2002, and his subsidiaries. Approximately 80% of total purchases for primary distribution are purchased from foreign sources (primarily Algeria, Russia, The Nederlands and Norway) under long-term contracts, which contain take-or-pay provisions, and transported to Italy through a network of over 3,700 thousand kilometers international pipelines of which Eni owns the transmission rights. The remaining purchases for primary distribution in Italy are obtained principally from domestic gas of Eni’s Exploration & Production segment. Through an about 30,000-kilometer long network (corresponding to 96% of the Italian domestic natural gas network), Eni supplies natural gas to residential and commercial users (civil market), industrial users and thermo-electric segment. Snam Rete Gas (Eni 59,76%), that was constituted in accordance to Law Decree 164/2000, owns the pipelines network used by Eni. Snam Rete Gas, which was rated on the Italian stock exchange market, engages in natural gas transportation activities also for other operators of the segment. Through Italgas, the largest retail gas distribution company in Italy, Eni engages in local gas distribution segment — retail supply and urban civil and commercial distribution —. Eni owns 98,285% in Italgas after the public offering for Italgas shares started in December 2002 and closed in January 2003. Eni is proceding with the squeeze out of the residual shares of Italgas. Eni also participates in local distribution outside Italy, in Argentina through Distribuidora de Gas Guyana, Hungary through Tigaz and in Slovenia through Adriaplin Doo.

Legislative Decree n. 164 of May 23, 2000 introduced laws for the liberalization of the Italian natural gas market with great impact on Eni’s activities, as the company is present in all the phases of the natural gas chain. The most important aspects of the decree are the following:

— |  | total market opening after 2003;
— |  | until December 31, 2010 the imposition of thresholds to operators in relation to a percentage share of domestic consumption set as follows: (i) 75%, by 2002, for imported or domestically produced natural gas volumes introduced in the domestic transmission network. This percentage decreases by 2 percentage points per year until it reaches 61% in 2009; (ii) 50% from January 1, 2003 for sales to final customers. These ceilings are calculated net of losses and own consumption;
— |  | tariffs for transport, dispatching, storage, use of LNG terminals and local network distribution are set by Authority for Electricity and Gas;
— |  | third parties will be allowed to access the regulated transmission system.

Eni through EniPower SpA (Eni 100%) and subsidiaries is engaged in generation and sale of electricity with a capacity of 1,000 megawatts through the power plants in Livorno, Taranto, Mantova, Ravenna and Brindisi and a generation of about 5 thousand gigawatts/hour and approximately 30% of this is used for internal consumption. Enipower manages the electrical development opportunities. The demand for gas and fuel oils of EniPower’s stations is fully internally bought.

REFINING & MARKETING: Eni engages in petroleum refining and marketing activities primarily in Italy, with additional operations in Europe, Africa, South America. Eni is the largest refiner of petroleum products in Italy in terms of overall refining capacity. Approximately 40% of crude oil sold is purchased from producing countries pursuant to purchase contracts (28%) and in international spot markets (12%), while the remainder is obtained from Eni’s Exploration & Production segment. Approximately 45% of the purchased crude oil is traded.

PETROCHEMICALS: through Polimeri Europa SpA and subsidiaries (Eni 100%), which own the Eni’s principal petrochemical businesses, and EniChem SpA, which owns the residual petrochemical businesses, Eni engages in manufacturing of olefins, aromatics, intermediate products, styrene and elastomers. Eni’s petrochemicals production is concentrated in Italy, the

143

##### Table of Contents

other operations primarily in West Europe. Approximately 50% of the oil-based feedstock requirements used by petrochemical plants are supplied by Eni’s Refining & Marketing division.

OILFIELD SERVICES AND ENGINEERING: through Saipem SpA (Eni 43%), which was rated on the Italian stock exchange market, and its subsidiaries, Eni is engaged in construction and drilling services to customers in the oil and gas industries. Through Snamprogetti SpA (Eni 100%) and subsidiaries, Eni is a leading provider of engineering and project management services to customers in the oil and gas and petrochemical industries. At December 31, 2002 approximately 13% of the order backlog of Eni’s Oilfield Services and Engineering segment related to orders from Eni Group companies.

Certain significant estimates

The preparation of the financial statements in conformity with Italian GAAP, along with the reconciliation to U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recent accounting pronouncements

In June 2001 and in April and June 2002, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 143 “Accounting for Assets Retirement Obligations” (“SFAS 143”), No. 145 “Rescission of FASB Statement No. 4, 44 and 64, amendment of FASB Statement No. 13 and technical corrections” (“SFAS 145”) and No. 146 “Accounting for cost associated with exit and disposal activities” (“SFAS 146”).

SFAS 143 “Accounting for Asset Retirement Obligation” provides the evaluation and recording criteria for liabilities arising from the disposal of tangible long-lived assets and associated asset retirement obligation be recognized in the period in which it is incurred, if estimable, concurrent with an increase in the related asset’s carrying value. The increase in the related asset’s carrying value is amortised to income over its useful life. Upon initial adoption, a liability is recognized for existing asset retirement obligations and the associated asset retirement cost is capitalized as an increase to the carrying value of the assets. The recognized liability and asset are adjusted for cumulative accretion and accumulate depreciation, respectively, from the time period when the asset retirement obligation would have originally been recognized had this statement been in effect to the date of adoption. Eni will adopt the standard beginning January, 2003.

SFAS 145 supersedes SFAS 4 “Reporting gains and losses from extinguishment of debt”, SFAS 44 “Accounting for intangible assets of motor carriers” and SFAS 64 “Extinguishment of debt made to satisfy sinking-fund requirements”. This statement establishes that gains and losses due to the extinguishment of debts can be recorded under extraordinary items only in case they are neither non-usual nor non-recurring items. In addition the statement modifies provision of SFAS 13 “Accounting for leases”, establishing that conversion of finance leases made after May 15, 2002, are recorded under the provisions for leaseback; such change has no effect. The remaining provisions of the statement are effective for all the fiscal quarters starting after May 15, 2002. Eni shall apply them beginning in 2003.

SFAS 146 supersede Emerging Issues Task Force (“EITF”) Issue No. 94-3 “Liability recognition for certain employee termination benefits and other cost to exit an activity (including certain costs incurred in a restructuring)” and provides the evaluation and recording criteria of costs associated to the exit or elimination of activities, including restructuring, establishing that liabilities can be recorded only in the case of present obligation for the company. At the beginning liabilities are evaluated at their fair value. In this next period such value can be modified to take into consideration new estimates and increasing related to time. This statement started after December 31, 2002. Eni shall apply it beginning in 2003.

In November 2002, the FASB issued Interpretation No. 45 “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“FIN 45”), which provides the recording criteria for guarantees issued or modified after December 31, 2002.

In January 2003, the FASB issued Interpretation No. 46 “Consolidation of Variable Interest Entities” (“FIN 46”), which modifies Accounting Research Bulletin No. 51 “Consolidated Financial Statements” and provides standards for determining under what circumstances a variable interest entity should be consolidated. Variable interest entities are companies in which another has an ownership, a contractual or financial relations that changes with changes in the equity’s net asset value. The requirements of FIN 46 apply immediately to variable interest entities created after January 31, 2002; the requirements apply to older entities that satisfies the provisions of FIN 46, in the first fiscal year or interim period beginning after June 15, 2003. Eni shall apply it beginning in 2004.

Eni is presently evaluating these statements and cannot predict whether their application will have a material impact on Eni’s financial position or operating result.

Results of operations from oil and gas producing activities

Results of operations from oil and gas producing activities represent only those revenues and expenses directly associated with Eni’s oil and gas production. These amounts do not include any allocation of interest expense or corporate overhead or amortization of goodwill and, therefore, are not necessarily indicative of the contributions to consolidated net earnings of Eni. Revenues and income tax expense include taxes owed by Eni but paid by government-owned entities on its behalf. Related income taxes are computed by applying the local income tax rates to the pre-tax income from producing activities.

Oil and natural gas reserves

Proved oil and gas reserves are the estimated quantities of crude oil (including condensate and natural gas liquids) and natural gas which on the basis of geological and engineering data will be able to be recovered with reasonable certainty in future years from known reservoirs under technical, contractual, economic and operating conditions existing at the time. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions. Proved reserves exclude royalties and interests owned by others. Proved reserves exclude royalties and interest owned by others.

Proved developed oil and gas reserves are proved reserves that can be estimated to be recovered through existing wells, facilities and operating methods. Proved undeveloped oil and gas reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells a relatively major expenditure is required for completion. Additional oil and gas reserves expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing natural forces and mechanisms of primary recovery are included as proved developed or proved undeveloped reserves only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.

The definitions used for proved oil and gas reserves are in accordance with applicable U.S. Securities and Exchange Commission regulation. The estimates of proved reserves, developed and undeveloped, at December 31, 1999, 2000, 2001 and 2002 are based on reports prepared by Eni.

Numerous uncertainties are inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures. The accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgement. Results of drilling, testing and production after the date of the estimate may require substantial upward and downward revision. In addition changes in oil and natural gas prices could have an effect on the quantities of Eni’s proved reserves because the estimates of reserves are based on prices and costs at the date when such estimates are made. In addition the reserves estimates are subject to revision as prices fluctuate due to the cost recovery feature under certain Production Sharing Agreements (PSA). Accordingly, the estimated reserves could be materially different from the quantities of oil and natural gas that ultimately will be recovered.

Eni operates under PSA in several of the foreign jurisdictions where it has oil and gas exploration and production activities. In countries where Eni operates under PSA’s, proved reserves are shown in accordance with Eni’s economic interest (pursuant to PSA contract terms) in the oil and gas reserve quantities estimated to be recoverable in future years. Such reserves include estimated quantities allocated to Eni for recovery of costs, income taxes owed by Eni but paid on its behalf and Eni’s net equity share after cost recovery.

Estimated reserves include the volume of natural gas withdrawn from certain Eni Italian fields and contained in Eni’s gas storage reservoirs in Italy used for responding to variations in gas demand due to seasonality (gas is usually stored during summer months for use during winter months, when demand typically peaks).

The following table presents yearly changes in estimated proved reserves, developed and undeveloped, of crude oil (including condensate and natural gas liquids) and natural gas for the years 2000, 2001 and 2002.

Standardized measure of discounted future net cash flows

Estimated future cash inflows represent the revenues that would be received from production and are determined by applying year-end prices of oil and gas to the estimated future production of proved reserves. Future price changes are considered only to extent provided by contractual arrangements. Estimated future development and production costs are determined by estimating the expenditures to be incurred in developing and producing the proved reserves at the end of the year. Neither the effects of future pricing nor expected future changes in technology and operating practices have been considered.

The standardized measure is calculated as the excess of future cash inflows from proved reserves less future costs of producing and developing the reserves, future income taxes and a yearly 10% discount factor.

Future cash flows as of December 31, 2000, 2001 and 2002 include annual payments from Gas & Power segment of Eni and other transport and distribution gas companies which represent payments for providing specified peak demand delivery capability. Such capability is provided through utilization of: (i) gas withdrawn from producing fields and injected into depleted gas fields as storage; (ii) gas acquired.

Future production costs include the estimated expenditures related to production of the proved reserves plus any production taxes without consideration of future inflation. Future development costs include the estimated costs of drilling development wells and installation of production facilities, plus the net costs associated with dismantlement and abandonment of wells and facilities, assuming year-end costs continue without considering future inflation. Future income taxes were calculated in accordance with the tax laws of the countries in which Eni operates.

The standardized measure of discounted future net cash flows, related to the preceding proved oil and gas reserves, is calculated in accordance with the requirements of Statement of Financial Accounting Standard No. 69. The standardized measure does not purport to reflect realizable values or fair market value of Eni’s proved reserves. An estimate of fair value would also take into account, among other things, the expected recovery of reserves in excess of proved reserves, anticipated changes in future prices and costs and a discount factor representative of the risks inherent in producing oil and gas.

Item 4

Authorisation to the Board of Directors to use Eni’s own shares to
implement stock grant plans for Eni Group managers

To the Shareholders:

The Board of Directors, in the exercise of the delegation of authority resolved by the Shareholders’ Meeting on May 30, 2002 and in consideration of 2001 Eni results, approved in the meeting held on July 2, 2002 to increase the share capital up to 1.5 million euro for no consideration by issuing up to 1.5 million shares, nominal value euro 1, bearing regular coupon, to be offered to Eni managers employed by the company and its subsidiaries controlled directly or indirectly by Eni S.p.A. pursuant to Article 2359 of the Civil Code, with the exclusion of listed subsidiaries, who have achieved the pre-set 2001 individual performances. Eni is committed to offer to said managers the subscription of the shares to be issued for no consideration within a month from the expiration of the three-year period commencing as of the date when the commitment to the offer has been taken. The subscription rights offered to 770 Eni Group managers in 2002 are 1,037,200 and they allow the subscription of a corresponding amount of Eni shares.

The Board intends to avail, also for the Financial Years 2003, 2004 and 2005 of an instrument to increase the commitment of Eni Management to the strengthening of its participation to the enterprise risk, to the enhancement of the shareholders value and to the achievement of Eni performances and results and proposes to use to this end Eni own shares instead of Eni shares issued through a capital increase, in order to take advantage of the higher operative flexibility of the disposal of shares in respect of a share capital increase. In each of the Financial Years 2003, 2004 and 2005, once ascertained the achievement of the company targets set in each previous year, Eni own shares will be offered for no consideration to the managers employed by the company and its subsidiaries controlled directly or indirectly by Eni S.p.A. pursuant to Article 2359 of the Civil Code, with the exclusion of subsidiaries whose shares are listed on regulated stock exchanges on the annual assignation date, who have achieved the related annual pre-set individual performances (the “Assignees”). The Board will then approve annual assignation plans for the Financial Years 2003, 2004 and 2005, based on Eni 2002, 2003 and 2004 results, respectively.

In order to implement the annual assignation of Eni shares , the Board proposes to the Shareholders’ Meeting to be authorised to assign for no consideration up to 6.5 million own shares (the “Shares”) to the Assignees. Eni is committed to offer to said managers the Shares within a month from the expiration of the three-year period commencing as of the date when the commitment to the offer has been taken. The right of the Assignee and the commitment of Eni S.p.A. may not be withdrawn.

The Board proposes also to be empowered to approve the annual assignation plans and the related regulations.
