HIGHLIGHTS

• In the first half of 2002 Eni recorded net income of euro 2,261 million. Before non-recurring items (euro 211 million) and before the attribution of net income of Snam Rete Gas to minorities (euro 199 million), Eni’s net income decreased by 14.7% over the first half of 2001 (euro 2,671 million as compared to euro 3,133 million) due mainly to a weak energy scenario with a sharp decline in international oil prices (oil down 11.8%, natural gas down 19.7%) and refining margins (Brent margin declined by 79%) over the first half of 2001, whose effects were offset in part by higher volumes sold and efficiency improvement actions. After non-recurring items and the attribution of net income of Snam Rete Gas to minorities, Eni’s net income decreased by euro 1,276 million compared to the first half of 2001, down 36.1%

• Daily hydrocarbon production reached the record level of 1,455,000 boe (up 6.5% over the first half of 2001), despite the production cuts decided by OPEC, due to increased production in established and newly acquired areas and the start-up of relevant projects. Portfolio rationalization continued and was aimed at concentrating assets in areas with significant growth potential and where Eni is operator

• In the Kazakh offshore of the North Caspian Sea, performed and ongoing appraisal operations have been confirming the importance of the Kashagan oil field, where Eni is single operator with a 16.67% interest. Recoverable reserves are in the range of 7 to 9 billion barrels on the basis of updated estimates, which makes Kashagan the largest oil discovery in the past 30 years

• Eni and EnBW (the third German operator in electricity) have agreed to acquire a 95.62% interest in GVS, the fourth operator in the German gas market, transporting and marketing about 8 billion cubic meters of gas per year. Eni’s expenditure amounts to euro 344 million. With this transaction, Eni enters the German natural gas market and consolidates its leading role in Europe

• The laying of the second and last line of the Blue Stream underwater gasline has been completed. It will transport natural gas (16 billion cubic meters per year when fully operational) from Russia to be sold jointly by Eni and Gazprom on the Turkish market. Testing is scheduled to be completed by the end of 2002 so that the gasline will start operations by that date

• Eni and the Portuguese Galp Energia (in which Eni holds a 33.34% interest) bought in equal shares the whole distribution network of TotalFinaElf in Spain, made up of 186 service stations and logistic assets. The agreement, which also includes the sale by Eni of 195 service stations in Italy and by Galp Energia of 111 service stations in Portugal to TotalFinaElf, is part of Eni’s selective development outside Italy and rationalization of presence in Italy in downstream activities

Due to the seasonality in demand for natural gas and certain refined products and the changes in a number of external factors affecting Eni’s operations, such as prices and margins of hydrocarbons and refined products, Eni’s results of operations and changes in net borrowings for the first half of the year cannot be extrapolated for the full year.

Net income for the first half of 2002 amounted to euro 2,261 million, with an euro 1,276 million decrease over the first half of 2001, down 36.1%, due to: (i) a decline in operating income (euro 1,544 million, down 25.2%) related in particular to lower international oil prices (oil down 11.8%; natural gas down 19.7%) and a sharp decline in refining margins (Brent margin declined by 79%); (ii) the negative change in the balance of net extraordinary expense/income (euro 523 million) due to lower gains on the sale of assets (euro 829 million), offset in part by lower restructuring charges recorded in the first half of 2002, mainly in the Petrochemical segment; (iii) the attribution of net income of Snam Rete Gas to minorities following its public offering of December 2001 (euro 199 million). These negative changes were offset in part by lower income taxes (euro 923 million, down 33.6%), due mainly to lower income before taxes.

Net income before non-recurring items (euro 211 million) and before the attribution of net income of Snam Rete Gas to minorities (euro 199 million) decreased by 14.7% (euro 2,671 million as compared to euro 3,133 million of the first half of 2001).

SEASONALITY

Eni’s results of operations reflect the seasonality in demand for natural gas and certain refined products used in residential space heating, the demand of which is typically highest in the first quarter of the year, which includes the coldest months, and lowest in the third quarter, which includes the warmest months.

4

Eni’s operating income for the first half of 2002 totaled euro 4,575 million, a decrease of euro 1,544 million over the first half of 2001, down 25.2%, due mainly to:

- a decrease in operating income recorded by the Exploration and Production division (euro 970 million, down 27.8%) related to lower international oil prices (oil down 11.8%; natural gas down 19.7%) and lower natural gas production sold in Italy (9.3 million boe, down 18.8%) mainly due to lower withdrawals from storage, as well as higher asset impairment (euro 78 million). These negative factors were partly offset by increased hydrocarbon production sold outside Italy (15 million boe, up 8.1%) and increased oil production sold in Italy (3.1 million barrels, up 26.3%) and gains on disposal of assets (euro 42 million);

- a decrease in operating income recorded by the Refining and Marketing segment (euro 544 million, down 81.7%) mainly due to a sharp decline in refining margins (Brent margin was down 79%), which bottomed at a ten-year low, offset in part by higher income from marketing activities related to higher commercial margins in European markets and in Brazil, offset in part by the effects of sales/closures of service stations in Italy.

Daily hydrocarbon production amounted to 1,455,000 boe (oil and condensates 919,000 barrels; natural gas 536,000 boe) increasing by 89,000 boe, up 6.5%, despite the 34,000 boe effect of production cuts decided by OPEC. The production increase was due to: (i) start-up of new fields mainly in Algeria, Congo, Angola, Nigeria, Italy, the United States, Iran and Pakistan; (ii) production increases registered mainly in the United Kingdom, Algeria and the United States. These increases were partly offset by declines of mature gas fields in Italy. The share of production outside Italy remained at 78%.

In the first half of 2002, streamlining continued and allowed cost savings amounting to euro 230 million, which offset salary increases and the effects of inflation.

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

Eni’s net sales from operations (revenues) for the first half of 2002 amounted to euro 23,904 million, representing a euro 2,114 million decrease over the first half of 2001, down 8.1%, due mainly to lower international oil prices and lower prices for main downstream products. These negative factors were offset in part by an increase in oil production sold and higher activity levels in the Oilfield Services and Engineering segment.

Revenues generated by the Exploration and Production division (euro 6,282 million) declined by euro 1,035 million, down 14.1%, due essentially to lower international oil prices (oil down 11.8%; natural gas down 19.7%), lower natural gas production sold in Italy (9.3 million boe, down 18.8% due mainly to lower withdrawals from storage) and lower volumes of purchased hydrocarbons marketed (21.6 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 hydrocarbon production sold outside Italy (15 million boe, up 8.1%) and increased oil production sold in Italy (3.1 million barrels, up 26.3%).

Revenues generated by the Gas & Power division (euro 8,434 million) declined by euro 362 million, down 4.1%, due essentially to lower prices for natural gas, also related to the change in the sale mix, whose effects were partially offset by the transfer of the natural gas trading activity from the Exploration and Production division.

Revenues generated by the Refining and Marketing segment (euro 10,433 million) declined by euro 1,152 million, down 9.9%, essentially due to lower prices for petroleum products (the retail prices of gasoline and diesel fuel were down 16.3% and 14%, respectively) and to reduced sales volumes on both the retail and wholesale markets in Italy (390,000 tonnes, down 3.5%), due primarily to closures/sales of service stations.

Revenues generated by the Petrochemical segment (euro 2,403 million) decreased by euro 469 million, down 16.3%, due mainly to the 18% fall in the average sales prices of products, partially offset by higher sales (up 3.4%).

Revenues from the Oilfield Services and Engineering segment (euro 1,934 million) increased by euro 699 million, up 56.6%, due to an increase in the level of activity, in particular in oilfield services.

35,037			18,021		17,323		(3.9	)

Operating expenses for the first half of 2002 (euro 17,323 million) decreased by euro 698 million compared to the first half of 2001, down 3.9%, essentially due to: (i) lower supply costs for natural gas and oil-based and petrochemical feedstocks; (ii) cost reductions resulting from streamlining and increased efficiency, which offset almost entirely the increase due to salary rises and inflation. These decreases were partially offset by higher activity levels in the Oilfield Services and Engineering segment.

Payroll and related costs (euro 1,466 million) decreased by euro 23 million, down 1.5%, mainly due to the decline in the number of employees in Italy resulting from the streamlining initiatives undertaken, whose effects were partially offset by an increase in unit labor costs in Italy.

As of June 30, 2002, employees were 72,902, with an increase of 497 employees over December 31, 2001, due to a 648 unit increase outside Italy offset in part by a 151 employee decline in Italy related to streamlining actions. The increase outside Italy was due mainly to new hiring on a fixed term base in oilfield services.

Depreciation, amortization and writedown charges in the first half of 2002 (euro 2,541 million) increased by euro 281 million, up 12.4% over the first half of 2001, due to the increases registered in the Exploration and Production division (euro 205 million), resulting from increased production and higher exploration activity (euro 53 million), and in the Oilfield Services and Engineering segment (euro 49 million) resulting from the entry into

7

operation of new investments. These increases were partly offset by lower depreciation and amortization charges in the Petrochemical segment (euro 74 million) following plant writedowns recorded in 2001 financial statements.

Writedowns (euro 105 million) concerned essentially proved and unproved properties (euro 85 million) and assets in natural gas secondary distribution in Argentina (euro 17 million) related to their decreased profitability prospects.

(1) Operating income of the first half of 2002 prudentially reflects the euro 62 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 and Production and Gas & Power divisions. These effects amounted to a euro 202 million decrease on operating income of the Exploration and Production division which delivers storage and modulation services and to a euro 202 million increase on operating income of the Gas & Power division which purchases said services.

Exploration and Production Operating income for the first half of 2002 totaled euro 2,515 million, representing a euro 970 million decrease over the corresponding period of 2001, down 27.8%, due mainly to: (i) lower international oil prices (oil down 11.8%; natural gas down 19.7%) related to the unfavorable energy environment; (ii) lower natural gas production sold in Italy (9.3 million boe, down 18.8%) due mainly to lower withdrawals from storage; (iii) higher writedowns of mineral assets (euro 78 million); (iv) a decrease in storage and modulation tariffs due to the effects of decision No. 49/02 of the Authority for Electricity and Gas (euro 62 million); (v) higher exploration costs (euro 53 million). These negative factors were offset in part by: (i) increased hydrocarbon production sold outside Italy (15 million boe, up 8.1%) and increased oil production sold in Italy (3.1 million barrels, up 26.3%); (ii) cost reductions related to synergies deriving from the integration of purchased companies and streamlining; (iii) gains on disposal of assets (euro 42 million).

Gas & Power Operating income in the first half of 2002 amounted to euro 2,003 million, a euro 59 million decrease over the first half of 2001, down 2.9%, due mainly to: (i) the negative effect of the change in the sale mix in primary distribution related to the higher share of sales in Europe destined to Italy; (ii) the payment of a new environmental tax (euro 32 million) established by the Sicilia Region with Regional Law No. 2 of March 26, 2002 (see: Operating Review — Gas & Power division); (iii) asset impairment in natural gas secondary distribution in Argentina (euro 17 million). These negative factors were offset in part by: (i) higher margins in secondary distribution related to higher tariffs and the positive

8

effect for 2001 (euro 72 million) of early estimates of the impact of the application of decision No. 122/02 of the Authority for Electricity and Gas (see: Operating Review — Gas & Power division); (ii) lower costs related to streamlining, in particular in transport activities in Italy, which were partly offset by salary increases and inflation.

Refining and Marketing Operating income in the first half of 2002 amounted to euro 122 million, a euro 544 million decrease over the first half of 2001, down 81.7%, due mainly to: (i) the unfavorable refining scenario (Brent margin was down 79%), related to weak demand and high stocks of refined products worldwide, as well as to lower margins on continent-based refineries following a reduction in Fob/Cif differentials; (ii) the fact that in the first half of 2001 the effect of a decrease in stocks (valued at Lifo) was recorded for euro 48 million; (iii) higher costs in maintenance of refineries, related to the early performance of planned maintenance due to the especially negative refining scenario of the second quarter of 2002; (iv) lower volumes sold in retail and wholesale markets in Italy due in particular to sales/closures of service stations (for a total of 846 units from June 30, 2001). These negative factors were offset in part by: (i) higher results in distribution due to the increase in commercial margins on European markets; (ii) increased results in LPG, mainly in Brazil, and lubricants activities; (iii) lower costs related to streamlining, offset in part by salary increases and inflation.

Petrochemicals Operating losses amounted to euro 141 million, an increase of euro 45 million over the corresponding period of 2001, up 46.9%, due to lower margins of products especially in the first quarter, reflecting a sharp decline in selling prices (an average decrease of 18%) as compared to a smaller decrease in oil-based feedstocks costs. These factors were offset in part by lower depreciation and amortization charges (euro 74 million) following plant writedowns recorded in 2001 and the positive effects of the price increase of the second quarter on the evaluation of stocks (euro 28 million).

Oilfield Services and Engineering Operating income for the first half of 2002 totaled euro 159 million. Oilfield services activities registered an operating income of euro 175 million with an euro 83 million increase, up 90.2%, due primarily to the Blue Stream contract and to the results obtained in the Onshore construction area, especially following increases in activity in the Far East, West Africa and Saudi Arabia, as well as the start-up of an important project in Algeria, whose positive effects were offset in part by the lower profitability of a number of contracts in the Offshore and Onshore drilling areas. Engineering activities recorded an operating loss of euro 16 million, due primarily to the euro 18 million provision to a reserve for litigation.

Other Activities This area includes overhead costs of Eni’s corporate and financial subsidiaries as well as the operating results of insurance businesses, real estate, information technology and administrative services and those of Tecnomare SpA, Eurosolare SpA and EniTecnologie SpA. Operating losses amounted to euro 83 million (a euro 5 million decrease over the first half of 2001).

NET FINANCIAL EXPENSE

In the first half of 2002 net financial expense (euro 81 million) decreased by euro 99 million over the first half of 2001, due mainly to lower interest rates on European markets (Euribor down 1.3 points) and lower average net borrowings for about euro 760 million.

9

NET INCOME FROM INVESTMENTS

Net income from investments in the first half of 2002 amounted to euro 50 million, as compared to a net income of euro 11 million in the first half of 2001 and represented the balance between income for euro 128 million and expense of euro 78 million. Income from investment concerned mainly: (i) Eni’s share of income on investments accounted for with the equity method (euro 76 million) in particular in the Gas & Power (euro 51 million), Refining and Marketing (euro 20 million) and Oilfield Services and Engineering (euro 5 million) segments; (ii) dividends from investments accounted for at cost (euro 31 million). Expense on investments was primarily due to Eni’s share of losses on investments accounted for with the equity method and at cost, in particular Inversora de Gas del Centro SA and Distribuidora de Gas del Centro SA (euro 28 million), Galp Energia SGPS SA (euro 19 million) and Blu SpA (euro 25 million).

Gains on disposals related to the sale of investments, businesses and fixed assets as a result of restructuring activities. In particular, gains on disposal in the first half of 2002 amounting to euro 48 million concerned mainly the sale of service stations in Italy (euro 24 million) and minor assets and investments (euro 24 million).

Provisions for risks and contingencies of euro 85 million related mainly the reserve for environmental risks in the Refining and Marketing (euro 26 million) and Petrochemical (euro 26 million) segments.

Redundancy incentives of euro 44 million concerned primarily the Refining and Marketing segment (euro 20 million), the Gas & Power division (euro 13 million) and the Petrochemical segment (euro 4 million). Writedowns for euro 38 million concerned essentially assets of the Priolo refinery.

Writedowns (euro 105 million) concerned mainly mineral assets (euro 85 million) and assets in secondary distribution of natural gas in Argentina (euro 17 million). Gains on disposals concerned the sale of mineral assets in the Exploration and Production division. The positive effects of stock revaluations concerned the effects of price increases on the revaluation of stocks in the second quarter in the Petrochemical segment. Income taxes concerned the estimated tax benefit of all non-recurring items.

INCOME TAXES

Income taxes (euro 1,822 million) decreased by euro 923 million over the first half of 2001, due mainly to a euro 1,929 million decline in income before taxes, the positive effect of the application of Law 342/00 and the net effect of the release of the reserve for anticipated amortization as per Law 498/01; these positive effects were 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%) in the United Kingdom.

MINORITY INTERESTS

Minority interests (euro 368 million) increased by euro 270 million over the first half of 2001, due to the attribution of net income of Snam Rete Gas SpA to minorities (euro 199 million) and higher net income earned by Saipem SpA and Italgas SpA.

(1) In the reclassified balance sheet, the purchase cost of 169,450,490 own shares held at June 30, 2002 is recorded as a decrease of net equity.

At June 30, 2002, net capital employed totaled euro 35,347 million, representing a decrease of euro 3,946 million over December 31, 2001, due mainly to: (i) a decrease (euro 2,262 million) of net working capital mainly related to the seasonality factors that determine revenue generation in the Gas & Power division; (ii) a decrease in non-current assets (euro 1,680 million) due to exchange rate differences resulting from the appreciation of the euro over other main currencies at June 30, 2002 as compared to December 31, 2001, whose effects were offset in part by new capital expenditure for the first half, net of amortization and depreciation charges. The share of the Exploration and Production and Gas & Power divisions on Eni’ net capital employed was 79.2% (79.0% as of December 31, 2001). The debt to equity ratio declined from 0.34 at December 31, 2001 to 0.32.

Net fixed assets (euro 32,903 million) were primarily related to the Exploration and Production (60.5%), Gas & Power (19.7%), and Refining and Marketing (9.8%) segments. Provisions for depreciation, amortization and writedowns (euro 38,353 million) represented 53.8% of gross fixed assets (53.2% at December 31, 2001).

Investments in unconsolidated subsidiaries and affiliates (euro 2,610 million) consisted primarily of 33.34% of Galp Energia SGPS SA (euro 726 million), 50% of Blue Stream Pipeline Company BV (euro 189 million), 49% of Greek natural gas secondary distribution companies EPA Thessaloniki and Thessaly (euro 191 million), 10.4% of Nigeria LNG Ltd (euro 115 million), 35% of Albacom SpA (euro 108 million), 50% of Transmediterranean Pipeline Co Ltd (euro 98 million), 49% of Superoctanos CA (euro 89 million), 49% of Azienda Energia e Servizi SpA (euro 84 million) and 50% of Raffineria di Milazzo SpA (euro 83 million).

12

Accounts receivable financing and securities related to operations (euro 1,594 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 Exploration and Production segment (euro 717 million) and in the Gas & Power segment (euro 725 million).

Net cash provided by operating activities (euro 7,268 million) and disposals (euro 319 million) enabled Eni to cover all the financial requirements related to capital expenditures and financial investments (euro 3,678 million) the payment of dividends for year 2001 (euro 3,033 million, of which euro 2,876 relating to dividends paid by Eni SpA), the buy-back of own shares (euro 234 million) and to decrease net borrowings by euro 1,618 million.

Income before minority interests has been adjusted by euro 2,509 million to take into account primarily depreciation and amortization (euro 2,437 million), writedowns of tangible and intangible assets and investments (euro 58 million) and an increase in the reserve for contingencies (euro 14 million).

Adjustments for dividends, interest, extraordinary income/expense and income taxes (euro 1,966 million) concerned income taxes (euro 1,822 million), net financial expense (euro 81 million) and net extraordinary expense (euro 93 million).

The decrease in net working capital (euro 1,265 million) was mainly due to the decrease in trade accounts receivable and other (euro 979 million) and an increase in trade accounts payable and other (euro 104 million).

The decrease in trade accounts receivable and other was mainly due to the seasonal factors that determine revenue generation in the Gas & Power division.

14

Dividends received, interest, extraordinary income (expense) and income taxes paid during the period (euro 1,045 million) concerned primarily the payment of income taxes for euro 945 million.

EXPLORATION AND PRODUCTION

EXPLORATION AND DEVELOPMENT

As of June 30, 2002, Eni’s portfolio of mineral rights consisted of 1,236 exclusive or shared rights for exploration and development in 39 countries on five continents, for a total net acreage of 304,143 square kilometers (317,283 at December 31, 2001). Of these, 41,792 square kilometers concerned production and development (41,841 at December 31, 2001). In Italy, net acreage decreased by 1,180 square kilometers, due to releases, and it decreased outside Italy by 11,960 square kilometers, due primarily to releases and sale of mineral rights in Egypt, Guyana, Algeria, Iran, Tunisia, the United Kingdom and Qatar. Mineral rights were acquired in Brazil and Norway.

In the first half of 2002, three-dimensional seismic surveys were carried out over 5,490 square kilometers (2,818 of which represented Eni’s share), while standard seismic surveys totaled 3,069 kilometers (1,307 of which represented Eni’s share), the former decreasing by 47.6% net to Eni and the latter by 72.3% net to Eni over the first half of 2001. These decrease may be attributed to the completion of survey campaigns mainly in Brazil and Italy, in the former and latter case, respectively.

Exploration expenditure amounted to euro 421 million (of which 93% was directed outside Italy), representing a 13.8% increase over the first half of 2001. Outside Italy, exploration expenditure concerned mainly the United States, Kazakhstan, Egypt, Russia, Angola and Nigeria. Expenditure in Italy concerned primarily offshore areas in the northern Adriatic Sea and in the deep waters of the Sicily Channel and areas in northern-central Italy.

Expenditure for the acquisition of proved and unproved property amounted to euro 201 million and concerned mainly the purchase of a 2.39% interest in the Kashagan field and of a 5.6% interest in the Bayu Undan field (see: “Portfolio Rationalization”).

Expenditure for development and capital goods totaled euro 1,941 million, of which 89% outside Italy, increasing by 34.2%. Development expenditure outside Italy concerned fields in Nigeria, Kazakhstan, Iran, Angola, Venezuela, Libya 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 the first half of 2002 amounted to euro 2,563 million, increasing by euro 712 million over the first half of 2001, up 38.5%.

In the first half of 2002 daily hydrocarbon production amounted to 1,455,000 boe (oil and condensates 919,000 barrels, natural gas 536,000 boe) increasing by 89,000 boe, up 6.5%, despite the 34,000 boe effect of production cuts decided by OPEC. The production increase was due to: (i) start-up of new fields mainly in Algeria, Congo, Angola, Nigeria, Italy, the United States, Iran and Pakistan; (ii) production increases recorded mainly in the United Kingdom, Algeria and the United States. These increases were partly offset by declines of

16

mature gas fields in Italy. The share of production outside Italy remained at 78%.

Daily production of oil and condensates (919,000 barrels) increased by 65,000 barrels, up 7.6%, due to increases registered outside Italy (68,000 barrels), in particular in: (i) Algeria, due to the start-up of the HBN (Eni’s interest 34.63%) and HBNS/BKNE (Eni’s interest 12.25%) fields; (ii) the United Kingdom, due to the full operation of the Elgin/Franklin fields (Eni’s interest 21.87%) and to the purchase of a 30% interest in the T-Block fields (Eni is operator with a 77.48% interest after the purchase) made in August 2001; (iii) in Congo due to the start-up of the Foukanda and Mwafi fields (Eni operator with a 65% interest) in the second half of 2001; (iv) in Egypt due to the production increase at the El Temsah concession (Eni’s share 25%) and (v) in Italy (18,000 barrels) due to the entry into operation of the Monte Alpi pipeline which transports oil produced in the Val d’Agri fields to Eni’s refinery in Taranto at the end of 2001. These increases were partly offset by a 21,000 barrels reduction outside Italy, in particular in Nigeria and Libya, due to production cuts decided by OPEC, as well as in Ecuador and China.

Daily production of natural gas (536,000 boe) increased by 24,000 boe, up 4.6%, due to the increases registered outside Italy (up 33,000 boe), in particular in the United Kingdom, the United States (in connection with the start-up of the King Kong/Yosemite field — Eni’s interest 50%), Pakistan and Croatia. These increases were offset in part by declines of mature fields in Italy (down 9,000 boe), in particular the Garibaldi/Agostino and Angela/Angelina fields.

Hydrocarbon production sold amounted to 256.1 million boe. The 7.2 million boe decrease over production was due to lower withdrawals as compared to allotted shares (underlifting1) outside Italy (3.7 million boe) and by natural gas production used for own consumption (3.5 million boe).

PORTFOLIO RATIONALIZATION

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

– the purchase of a further 2.39% interest in the Kashagan project in Kazakhstan (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. This sale obtained the necessary authorization from the relevant authorities;

– the sale to TotalFinaElf of Eni’s 25% interest in the Gorgoglione concession where the Tempa Rossa field is located, in Southern Italy. This purchase obtained the necessary authorization from the relevant authorities;

– the sale to TotalFinaElf of Eni’s 45% interest in the Alkaliji oil field offshore Qatar (Eni’s only interest in this country) with daily production of 12,000 barrels net to Eni;

(1) Agreements between partners regulate the right to withdraw proportional amounts of production in the period. Higher or lower volumes withdrawn as compared to entitlements determine a temporary over or underlifting.

17

– the purchase from British company 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 6,000 boe/day net to Eni, and associated exploration interests to Centrica. The swap deal foresees the payment of a cash balance to Centrica; evaluation of this balance is underway. The Liverpool Bay fields (Eni’s interest after the purchase 53.9%) started production in 1995 and currently produce approximately 110,000 boe/day (59,000 net to Eni). Always in the British section of the North Sea, Eni sold its interest in the Banff (12.4%), Hudson (19.5%) and Otter (19%) oil fields as well as associated interests in the Brent Pipeline System and Sullom Voe Terminal and exploration licenses to Dana Petroleum Ltd. This transaction is part of Eni’s rationalization process in the British section of the North Sea after the acquisition of British Borneo and Lasmo;

– the purchase from KerrMcGee of a further 5.6% interest in the Bayu Undan natural gas and condensates field (Eni’s interest 12.32% after the purchase), presently under development, located in the Zoca 91-12 (Undan) and Zoca 91-13 (Bayu) concessions in the Cooperation Area between Australia and East Timor.

The sale transactions defined amounted to a total of euro 358 million (of which euro 200 million related to those finalized in the first half of 2002); the purchase transactions defined entailed expenditure amounting to euro 201 million.

MAIN EXPLORATION AND DEVELOPMENT PROJECTS

Italy A new 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. The well has confirmed the mineral potential of this new gas field; according to preliminary studies recoverable reserves² could be around 9-12 billion cubic meters (equivalent to 57-76 million boe). A second exploration well will be drilled in the second half of 2002. In this area other structures have already been identified which could contain hydrocarbon reserves.

North Africa In Algeria, the fourth oil treatment line in the Hassi Berkine South oil center in the Algerian desert (HBNS, Eni interest 12.25%) has started operations bringing production to 285,000 barrels of oil per day.

In Libya, within the joint development of the natural gas, oil and condensates Wafa field and of structure C in the NC-41 permit, two contracts were awarded: (i) an EPC contract to the JVC Technimont-Sofregaz consortium for the design and construction of plants for hydrocarbon treatment near Wafa (this contract amounts to euro 1.2 billion); (ii) a turnkey contract to the Saipem-Hyundai Heavy Industries consortium for the construction and installation of a production platform offshore western Libya (this contract amounts to euro 620 million — see Operating Review of the Oilfield Services and Engineering segment).

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 and production is expected to be carried out with an FPSO vessel (Floating Production Storage Offloading).

West Africa In Angola in Block 14 (Eni’s share 20%) the delimitation well Landana 2 A was successfully drilled at a water depth of 400 meters reaching a depth of 3,900 meters, where it found a 120-meter layer of good quality oil (36°API) confirming the size of the Landana field. Always in Block 14 a new offshore oil discovery was made with the Gabela 1 well, which was drilled at a water depth of over 320 meters, penetrating a 25-meter net interval of oil-bearing porous rock, 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.

In Nigeria in offshore permit OPL 219 (Eni’s interest 12.5%) an oil discovery was made in the Bolia 1X well, drilled at a water depth of 1,100 meters to a total depth of 3,730 meters which found significant amounts of oil and yielded 6,000 barrels/day in test production.

Rest of World 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. The adopted development scheme offers the greatest operative flexibility and will enable Eni and INA to ship their equity production to the most profitable markets. Total investment in the project is about euro 320 million. Production will start at the end of 2004.

In Indonesia, three appraisal wells have been successfully completed in the fields of Ranggas, Gendalo and Gandang, in the Rapak and Ganal area (Eni interest 20%) in the deep offshore of eastern Kalimantan. The fourth delimitation well drilled in the oil field of Ranggas, at a water-depth of 1,590 meters flowed at a daily rate of more than 8,000 barrels of oil, confirming the extension of the field. The second appraisal 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 third delimitation well, drilled at a water-depth of 1,550 meters flowed at a daily rate of about 1 million cubic meters of gas and about 2,000 barrels 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. Construction of the plants is expected to be completed by 2005.

In Kazakhstan, within the North Caspian Sea project for the development of the Kashagan field (Eni’s share 16.67%) in the Kazakh offshore, the second appraisal well (KE-3) confirmed the importance of the discovery allowing to define the amount of recoverable reserves of oil in 7 to 9 billion barrels. The third appraisal well (KE-5) is being drilled, and in August drilling of the fourth well (KE-4) started. The front-end engineering for the first development phase was approved. On June 30, 2002 the consortium and the Kazakh authorities declared the saleability of reserves from this field. Within six months from this announcement the Consortium has to file a development plan to the Kazakh authorities, which in turn are to approve it within one month.

In Pakistan, Eni obtained in a consortium with other operators, among which Pakistan Petroleum, an exploration licence covering an area of 730 square kilometers in the Sukkur and Khaipur districts, in the Sindh province. Working plans for the next three years include the drilling of an exploration well in the Miano II-S-O block (Eni’s interest 33.3%) and the construction of 200 kilometers of seismic lines. The concession for the development of the Zamzana natural gas field (Eni’s interest 17.75%) was obtained.

19

In the United States a new discovery was made in the Green Canyon Block 516 (Eni’s interest 50%), in the deep waters of the Gulf of Mexico 240 kilometers south-west of New Orleans. In March 2002 production started at the King Kong/Yosemite natural gas well, only thirteen months from the decision to develop them and eight months after the discovery of Yosemite, at an initial level of 20,000 boe/day with the aim of reaching a peak of 25,000 boe before year-end (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 production 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 in the deep waters of the Gulf of Mexico, 290 kilometers south of New Orleans, the delimitation well of field K2 (operated by Eni with an 18.2% 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.

Storage services are provided by Stogit to its customers through eight storage fields located in Italy, based on nine storage concessions³ vested by the Ministry of Productive Activities.

In implementation of its decision No. 26 of February 27, 2002, with decision No. 49/02 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. Tariffs set by the Authority are 50% lower than those applied by Eni in the past. Stogit filed an appeal against both Authority decisions with the Regional Administrative Court of Lombardia requesting their cancellation.

NATURAL GAS

MERGER OF SNAM SpA INTO ENI SpA

In implementation of the decision of the General Shareholders’ Meeting of June 2, 2001, on January 30, 2002, Snam SpA was merged into Eni SpA. On February 1, 2002 (effective date of the merger) the new Gas & Power Division of Eni, which is entrusted with managing natural gas and power generation activities in Italy and outside Italy, became operational.

SUPPLY AND SALES

In the first half of 2002, Eni supplied 33.65 billion cubic meters of natural gas for primary distribution, with a 0.61 billion cubic meter increase over the first half of 2001, up 1.8%, in line with the increase in volumes sold. Higher purchases concerned imports from Norway (2.32 billion cubic meters) due to the start of imports in the second half of 2001, and the Netherlands (0.68 billion cubic meters), while lower purchases concerned domestic production (1.3 billion cubic meters) and imports from Algeria (0.93 billion cubic meters). Imports of natural gas covered 81% (77% in the first half of 2001).

Natural gas sales in primary distribution (33.26 billion cubic meters) increased by 0.79 billion cubic meters over the first half of 2001 (up 2.4%), due to higher sales in Europe destined to Italy (2.93 billion cubic meters) offset in part by a 2.22 billion cubic meters decline in sales in Italy.

Sales of natural gas in Italy (29.39 billion cubic meters) decreased by 2.22 billion cubic meters, down 7%, due mainly to lower sales to: (i) wholesalers (1.39 billion cubic

21

meters) due to the beginning of supplies at the border to Plurigas SpA in the fourth quarter of 2001; (ii) industrial users (0.74 billion cubic meters) due to the interruption of interruptible supplies occurred in the first two months of the year in coincidence with demand peaks from residential and commercial users in the same period and lower sales to continuous industrial customers.

Sales in Europe destined to Italy (3.76 billion cubic meters) increased by 2.93 billion cubic meters, up 353%, due to the progressive coming on line of long-term supply contracts to Italian importers (Plurigas, Edison, Dalmine, Cir Energia).

Sales of natural gas in secondary distribution in Italy (4.71 billion cubic meters) increased by 0.21 billion cubic meters, up 4.7%, due mainly to the approximately 110,000 units increase in the number of customers served (5.61 million as of June 30, 2002) and to a cold winter. Municipalities served as of June 30, 2002 were 1,186 (1,186 as of December 31, 2001).

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 company operating natural gas distribution in Pisa. Eni’s expenditure amounted to euro 42 million.

With decision No. 122 of June 26, 2002, the Authority for Electricity and Gas changed and complemented its decision No. 237 of December 28, 2000, which defined the new tariff regime for natural gas distribution and supply to eligible customers. 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, and therefore annulled the part of decision No. 237 which determined such parameters. The changes introduced by decision No. 122 concern in particular 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. For these companies, the procedure for the determination of capital employed is based on the method of historic cost, instead of the application of parameters. For all the distributors whose financial statements were not audited, the parameters determined in decision No. 237 still apply. Revenues from Eni’s secondary distribution in Italy in the first half of 2002 were determined based on the first estimates of the impact of decision No. 122.

Sales in secondary distribution outside Italy (1.94 billion cubic meters) were substantially stable (2 billion cubic meters in the first half of 2001).

(1) Include volumes destined to domestic storage.

Under Regional Law No. 2 of March 26, 2002, the Sicilia Region introduced an environmental tax on owners of primary pipelines in Sicily (i.e. pipelines operating at a maximum pressure of over 24 bar). 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 for 2002 totals approximately euro 97 million (nine monthly instalments of approximately euro 10.8 million).

In view of the compulsory nature of this environmental tax, Snam Rete Gas has paid due instalments within the established time limits, according to the procedures set out in the

23

decree issued on April 8, 2002 by the Director-general of the Sicilian regional finance and credit department. The introduction of the tax gives rise to an additional liability which Snam Rete Gas took into account in March 2002 when submitting its proposal to the Italian Authority for Electricity and Gas (“the Authority”) regarding tariffs for the 2002-2003 gas year.

On the strength of authoritative legal opinions and fiscal advice, Snam Rete Gas maintains that this tax is illegitimate for a number of reasons, including: (i) infringement of European rules which exclude customs duties, and any other taxes having the same effect, on the import, export and transit of natural gas, as well as infringement of the Constitution of the Italian Republic which prohibits any hindrance to the free movement of persons and things between the Regions; (ii) inconsistency between the declared environmental purposes of the tax and the absence of any kind of pollution attributable to the premise on which the tax is based, especially in view of the fact that gas pipeline laying is always followed by environmental restoration at the expense of the pipeline owners; (iii) non-observance of the principles of coordination, both with the laws of the State and with those of other Regions, given that the Sicilia Region has legislated without waiting for the specific provisions of the State setting out the fundamental principles “of coordination of public finance and the tax system”.

Snam Rete Gas has lodged claims with the Sicilia Region requesting reimbursement of the sums paid, as a preliminary step for legal proceedings, and intimating their entailment considering that reimbursement is due.

For the Authority (ruling 120/02 published on July 3, 2002), the environmental tax levied by the Sicilia Region on Snam Rete Gas’s pipelines is deemed to be inapplicable because it is at variance with European rules that are directly applicable at national level. The Authority has therefore ruled that the new cost affecting the gas transmission service cannot be included in tariffs. Its inclusion will take place automatically and retroactively only if the legitimacy of the regional tax is ascertained by the competent judicial authorities. Regarding the alleged illegitimacy of the tax, the Authority has sent a note to the European Commission (ruling 112/02) and has notified the Italian Parliament (ruling 113/02). The Italian government was similarly notified with ruling 96/02 of May 23, 2002. In the Authority’s opinion, the regional law is at variance with the directly applicable rules of the European directive to liberalize the internal market in natural gas (98/30/EC) which makes provision for public-service obligations, such as environmental protection, on condition that such obligations shall be “clearly defined, transparent, non-discriminatory and verifiable” and shall be published and notified to the European Commission without delay. These conditions are not complied with by the Sicilian law which introduces a discrimination between infrastructures depending on the type of goods transported and the import entry point without the discrimination being effectively justified on environmental grounds. The amount of tax revenue bears no relationship to any effective environmental damage specifically attributable to gas pipelines. The tax is also contrary to the Treaty establishing the European Community which prohibits Member States from imposing customs duties, and any other taxes having the same effect, both in relations between Member States and, after the introduction of the Common Customs Tariff, with third countries, and which also prohibits the adoption of measures that hinder imports. The Authority has authorized Snam Rete Gas to include clauses in agreements with its customers in order to guarantee a rapid definition of adjustments in the company’s favor if the tax proves to be payable.

While maintaining that this tax is illegitimate under the Italian Constitution and European rules (a petition having been submitted to the European Commission notifying it of the facts), Snam Rete Gas nevertheless considers that the regional law is applicable and in effect until

24

such time as its illegitimacy is ascertained by the competent judicial authorities and that, until such judgment is passed, there are no legal grounds whereby it can avoid the obligation to pay the tax, also bearing in mind that failure to pay gives rise to sanctions.

In order to protect its interests, Snam Rete Gas: (i) will lodge an appeal with the Regional Administrative Court of Lombardia to obtain immediate recognition in tariffs of a cost that is due and has effectively been incurred by the company; (ii) in September, when the circumstances materialize constituting tacit rejection of the request for reimbursement of the first instalment, will lodge an appeal with the Tax Commission of Palermo aimed at obtaining a definitive and rapid decision ascertaining the legitimacy of the tax; (iii) on July 30, 2002, lodged a complaint 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.

With decision No. 146 of July 31, 2002, the Authority approved the transport tariffs presented by Snam Rete Gas SpA for the thermal year 2002-2003 without taking into account the new tax imposed by the Sicilia Region. If the legitimacy of said tax is established, the decision provides for an automatic and retroactive adjustment of tariffs according to the provisions of its decision No. 120 of June 26, 2002.

The Authority, with decision 128/02 published on 11 July 2002, approved the tariff proposal submitted by GNL Italia on 28 March 2002 for the 2002-2003 gas year regarding the use of the Panigaglia LNG terminal. In order to encourage the development of new re-gasification terminals, the Authority, with ruling 91/02 published on 16 May 2002, set out regulations governing access to LNG terminals in the event of the construction of new facilities and/or the expansion of existing facilities.

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. 164/00.

Decision No. 137/02 established priority criteria for the concession 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 periods of peak demand for natural gas (i.e. winter). In the event of congestion at entry points, natural gas volumes not receiving a priority are given available transmission capacity on a pro-rata basis.

Decision No. 137/02 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.

Eni considers decision No. 137/02 non consistent with the overall legislative picture, especially with reference to Directive 98/30/CE and Legislative Decree 164/00, and is therefore evaluating the option to file a complaint with the relevant Courts.

DEVELOPMENT ACTIVITIES

Eni and EnBW (Energie Baden-Württemberg AG, the third German operator in electricity) have agreed to acquire through a 50/50 joint venture (EnBW-Eni Verwaltungsgesellschaft mbH) a 95.62% interest in GVS (Gasversorgung Süddeutschland GmbH), the fourth operator in the German gas market. The remaining 4.38% interest is the object of a put option open to minorities, which can be exercised in the two years following the main transaction at the same price conditions. The purchase contracts of GVS’s shares also provide for the transfer to EnBW-Eni of a 46.14% interest in EBS, a company in which GVS holds a 51% interest, which in turns owns interests in other companies is the area of natural gas distribution and co-generation. The transaction is expected to be closed in October 2002, after the relevant EU agencies express their approval. Eni’s total expenditure will amount to euro 344 million.

GVS transports and markets about 8 billion cubic meters of gas per year to local distribution companies serving about 750 local municipalities in the south-western areas of the country through an approximately 1,880-kilometer long gas pipeline network. In 2001 its revenues reached about euro 1.7 billion. With this interest in GVS, Eni enters the German natural gas market and confirms its leading role in Europe.

Eni and Gazprom hold equal shares in Blue Stream Pipeline Company BV, which will operate the gas pipeline linking the Russian to the Turkish coast of the Black Sea currently under construction. 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 25-year long contract. The overall project is worth about dollar 2.4 billion and entails the laying in deep waters of two parallel underwater lines, each 380-kilometer long and the construction of a compressor station on the Russian coast. Laying, which reached a record depth of 2,150 meters, was completed in February for the first line and in June 2002 for the second line. The conclusion of testing activities and the entry into service of the gasline are expected before the end of September and December 2002, respectively; the compressor station is expected to be completed in the second half of 2003. Volumes transported and sold are expected to increase progressively from 2002 onwards and to reach 16 billion cubic meters per year (8 billion net to Eni).

In Spain Eni started its supplies to Iberdrola of liquefied natural gas. The supply is coming from the Ras Laffan Liquefied Natural Gas plant in Qatar. LNG carried by Eni’s LNG Portovenere, was delivered to the Barcelona regasification terminal. This supply is regulated by the agreements signed in Madrid in December 2000 and will reach 1.2 billion cubic meters of gas per year for a period of 15 years. The gas will be used to fuel the combined-cycle power plant of Castellon (near Valencia) that with a capacity of 800 megawatt.

POWER GENERATION

In the first half of 2002, sales of electricity amounted to 2,605 gigawatthour, of which approximately 26% to other Eni segments. Sales of steam amounted to 4,993,000 tonnes. Eni sold 790 gigawatthour of purchased electricity to eligible customers.

	10,024	Steam (thousand tonnes)		5,164		4,993		(3.3	)

In May 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 1,000 megawatt, which will be able to produce about 7 billion kWh/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 of the three units and its startup are 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 area 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.

In July work started for the construction of two new combined cycle units with a total capacity of 770 megawatt in the Ravenna thermoelectric power station, which will reach a total power of over 900 megawatts and will produce about 6.4 billion kilowatthour/year. This power station will also produce thermal energy (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 emission 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 the first half of 2002, capital expenditure in the Gas & Power division totaled euro 446 million, decreasing by euro 124 million over the first half of 2001, down 21.8%, relating in particular to: (i) development and maintenance of Eni’s primary transmission and distribution network in Italy (euro 136 million); (ii) the continuation of the development plan of electricity generation capacity (euro 113 million), in particular for the Ferrera/Erbognone (Sannazzaro) and Ravenna power stations; (iii) the purchase of pipes (euro 96 million) destined to the construction of the gasline that will carry natural gas from the Libyan fields of Wafa and structure C in the permit NC-41 operated by Eni to Sicily (see: Main exploration and development projects, of the Exploration and Production segment); (iv) development and maintenance of urban networks in Italy (euro 86 million).

REFINING AND MARKETING

MERGER OF AGIP PETROLI SpA INTO ENI SpA

The General Shareholders’ Meeting of May 30, 2002, decided the merger of AgipPetroli SpA into Eni SpA. This merger, effective from February 1, 2002, follows that of Agip SpA (1997) and Snam SpA (2001) and allows for the completion of the divisionalization process of Eni, in line with the set up of the major international oil companies.

SUPPLY AND TRADING

In the first half of 2002, a total of 29.31 million tonnes of oil were purchased (28.09 in the first half of 2001), of which 16.64 million tonnes from Eni’s Exploration and Production segment. Some 12.91 million tonnes were resold, representing an increase of 2.01 million tonnes, up 18.4%, over the first half of 2001. In addition, 2.34 million tonnes of intermediate products were purchased (2.16 in the first half of 2001) to be used as feedstocks in conversion plants and 8.00 million tonnes of refined products (7.18 in the first half of 2001) sold on markets outside Italy (5.35 million tonnes) and as a complement to own production on the Italian market (2.65 million tonnes).

REFINING

Refinery intake processing in Italy and outside Italy (19.62 million tonnes) was substantially stable. The overall balanced capacity utilization rate of wholly owned refineries was also stable (92% as compared to 93% in the first half of 2001). About 39.1% of all oil processed came from Eni’s Exploration and Production division (32.9% in the first six months of 2001).

Within its strategy of obtaining a better balance of its refining capacity, Eni signed a contract with Erg Petroli for the establishment of Erg Raffinerie Mediterranee, a new company controlled by Erg which will own Eni’s Priolo and Erg’s Melilli refineries in Sicily and ancillary power plants. The project needs to be approved by the Italian Antitrust Authority and is aimed at rationalizing the organizational and industrial set up of the two refineries and at creating a refining pole capable of competing on international markets, in particular in the Mediterranean area, also integrated downstream with Eni’s petrochemical facilities and Erg’s power station which produces electricity using the refineries’ heavy residues. The new company shall: (i) integrate the refineries also through the construction of pipelines in order to attain the organizational and management synergies deriving from the high level of complementarity of the refining plants; (ii) implement development projects concerning the ancillary power stations.

DISTRIBUTION OF REFINED PRODUCTS

Sales of refined products (25.64 million tonnes) decreased by 0.21 million tonnes, down 0.8%; lower retail and wholesale sales (0.46 million tonnes of which 0.39 million tonnes in Italy) and lower sales to oil companies, traders and power plants (0.15 million tonnes) were offset in part by higher sales to Eni’s Petrochemical segment (0.16 million tonnes) and increased sales of marine fuels (0.24 million tonnes).

Retail sales in Italy

Retail sales in Italy (5.48 million tonnes) decreased by 280,000 tonnes, down 4.9% due mainly to the sale/closure of 810 service stations as compared to June 30, 2001 related to network streamlining with a related 2.2 points decrease in market share (from 39.9 of the first half of 2001 to 37.7%). Average throughput grew by 3.1% from 796,000 liters in the first half of 2001 to 821,000 liters.

At June 30, 2002, Eni’s retail distribution network consisted of 8,098 service stations (67.5% of which wholly owned), a 253 unit decrease over December 31, 2001, due mainly to divestments related to the agreements defined with Tamoil in 2001.

Retail sales outside Italy

Retail sales outside Italy (2.01 million tonnes) were stable.

As of June 30, 2002, Eni’s retail distribution network outside Italy consisted of 3,356 service stations (the same as at December 31, 2001). Eni continued its strategy of selective development in consolidated areas with good growth prospects, in particular:

• with its Portuguese partner Galp Energia (in which Eni holds a 33.34% interest) Eni bought in equal shares the whole distribution network of TotalFinaElf in Spain made up of 186 service stations, with a total throughput of 620 million liters/year, and a storage site with a capacity of over 100,000 liters located on the Spanish Mediterranean coast. The agreement approved by the relevant antitrust authorities, also includes the sale by

29

Eni of 195 service stations in Italy (with an average throughput of 270 million liters/year) and by Galp Energia of 111 service stations in Portugal (with an average throughput of 260 million liters/year) to TotalFinaElf;

•

Eni signed an agreement with Tamoil for the purchase of refined products distribution activities in Eastern Europe. These include in particular 23 service stations in the Czech Republic, 6 in Slovakia and 11 in Hungary with a throughput of about 45, 11 and 15 million liters per year, respectively. After the completion of the purchase, that will be submitted for approval to the relevant antitrust authorities, Eni’s market share will increase from 4.1% to 5.7% in the Czech Republic, from 2.2% to 3.4% in Slovakia and from 5% to 5.7% in Hungary.

Wholesale sales and other sales

Sales on wholesale markets in Italy (5.20 million tonnes) decreased by 110,000 tonnes, down 2.1%, due mainly to lower sales of jet fuel. Market share decreased by 1.2 percentage points from 24.3 to 23.1% due to the higher domestic consumption share of sales of fuel oil to the thermoelectric sector; Eni’s sales to this segment were not material.

Sales to Eni’s Petrochemical segment (2.23 million tonnes) increased by 160,000 tonnes, up 7.7%, while other sales (3.60 million tonnes) decreased by 210,000 tonnes, down 5.5%, due mainly to lower sales of jet fuel.

Outside Italy, wholesale sales (2.61 million tonnes) were stable. Other sales (4.51 million tonnes) increased by 300,000 tonnes, up 7.1%, due mainly to higher sales to other oil companies.

LPG

Retail and wholesale sales in Italy (404,000 tonnes) decreased by 16,000 tonnes, down 3.8%, while market share (20.6%) decreased by 1.3 percentage points.

Outside Italy, wholesale sales amounted to 860,000 tonnes with a decrease of 10,000 tonnes, down 1.1%. Market share in Brazil (21.1%) and in Ecuador (38.5%) were stable.

30

CAPITAL EXPENDITURE

In the first half of 2002, capital expenditure amounted to euro 204 million, increasing by euro 37 million, up 22.2%, over the first half of 2001 and concerned: (i) refining and logistics in Italy (euro 63 million, of which 9 in logistics) aimed in particular at maintaining plant efficiency and measures taken to comply with health, safety and environmental standards and regulations; (ii) the Italian network for the distribution of refined products (euro 56 million) in particular for the restructuring, upgrade and construction of new service stations (euro 51 million) and measures taken to comply with safety, health and environmental standards and regulations (euro 5 million); (iii) activities outside Italy (euro 49 million) representing 24% of the total and concerning primarily the upgrade of the distribution network in France and the upgrade of the LPG distribution network in Brazil (euro 11 million). Expenditure on compliance with regulations on health, safety and the environment amounted to euro 29 million (14% of the total).

31

PETROCHEMICALS

MARKET

In the first half of 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, in particular basic petrochemicals and polyethylene, due to a decrease in selling prices, higher than the decline in prices of oil-based feedstocks. The situation was especially serious in the first quarter, when the cracker margin reached its lowest level since 1989. Forecasts for the rest of the year indicate a slight recovery of consumption and margins (see: “Management expectations of operations”).

The prices of Eni’s principal products decreased on average by 18%; the main declines concerned olefins (down 20.3%), in particular ethylene and butadiene, polyethylene (down 20%), in particular HDPE and LDPE and aromatics (down 18.5%).

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 were not transferred.

With this operation all the activities related to the ethylene cycle were given an integrated and consistent setup so that they can be included in relevant negotiations for the sale of a significant share in Polimeri Europa in its new setup. In April, also due to problems emerged at some of the plants planned to be sold, Eni interrupted its negotiations with Arabian company Sabic which aimed at creating a joint venture related to Eni’s petrochemical activities conferred to Polimeri Europa. In line with Eni’s strategy of reducing its capital employed in petrochemicals and with Sabic’s strategy of increasing its presence in Europe, both companies expressed their willingness to discuss future opportunities related to the sale of individual petrochemical assets.

In the first half of 2002 Eni shut down the Porto Torres soda-chlorine plant.

SALES — PRODUCTION

Sales of petrochemical products (3,358,000 tonnes) increased by 149,000 tonnes, up 4.6%, due to the building up of stocks by end users, in particular of polyethylene and basic chemicals. At June 30, 2002, Eni’s sales network covered 20 countries; 52% of petrochemical revenues were represented by sales in Italy, 40% by sales in the rest of Europe, and 8% by sales in the Americas and Asia (52%, 39% and 9% respectively at June 30, 2001).

Production (4,919,000 tonnes) decreased by 140,000 tonnes, down 2.8% due to the sale of the polyurethane business and the shutdown of one soda-chlorine line.

32

Total nominal production capacity declined by 1.2%, due to the sale of the polyurethane business. The average capacity utilization rate calculated on nominal capacity decreased by one percentage points (from 74 to 73%), due to lower production of soda-chlorine.

About 36% of total production was directed to Eni’s own production cycle (42% in the first half of 2001).

Oil-based feedstocks supplied by Eni’s Refining and Marketing segment covered about 57% of requirements in the first half of 2002 (64% in the first half of 2001).

Basic petrochemicals

Sales of basic petrochemicals (1,977,000 tonnes) increased by 137,000 tonnes, up 7.4%, due to increased sales of intermediates (up 20%, mainly phenol and acetone) and aromatics (up 16%, mainly benzyl).

Basic petrochemical production (3,424,000 tonnes) decreased by 36,000 tonnes, down 1%, due mainly to the shutdown of one soda-chlorine line. Core business products registered a 1% average increase.

Styrene and Elastomers

Styrene and elastomer sales (601,000 tonnes) were stable as compared to the first half of 2001; higher polystyrene (up 5%) and thermoplastic rubber (up 11%) sales were offset by lower styrene (down 4%) sales and the general decline in sales of all other elastomers (down between 3 and 5%).

Production (795,000 tonnes) decreased by 21,000 tonnes, down 2.6%. Declines concerned both businesses.

Polyethylene

Sales of polyethylene (780,000 tonnes) increased by 98,000 tonnes, up 14.4%, due to the general increase in all products (in particular LDPE increased by 23%), except for HDPE, whose sales were stable.

Production (700,000 tonnes) increased by 8,000 tonnes, up 1.2%.

CAPITAL EXPENDITURE

     In the first half of 2002, capital expenditure amounted to euro 120 million, with a decrease of euro 110 million, down 47.8% due to the fact that in the first half of 2001 Eni purchased (euro 108 million) the gas phase licence from Union Carbide in the Polimeri Europa Brindisi plant. Capital expenditure concerned in particular actions for safety and environmental regulations, actions for the improvement of reliability and safety of plants, upgrade and increase of production capacity, and construction of storage sites.

OIL FIELD SERVICES
AND ENGINEERING

MARKETING PERFORMANCE

Orders acquired in the first half of 2002 (euro 3,171 million) increased by euro 1,216 million over the first half of 2001, up 62.2%. About 96% of new orders acquired was represented by work to be carried out outside Italy, and 25% by work originated by Eni companies. Eni’s order backlog reached euro 8,119 million at June 30, 2002, with an increase of euro 1,350 million, up 19.9% as compared to December 31, 2001. Projects to be carried out outside Italy represented 72% of the total order backlog, while orders from Eni companies amounted to 16% of the total.

Among the most significant orders won are:

in oilfield services: in the Offshore construction area: (i) in a consortium with Hyundai Heavy Industries a turnkey contract for the construction and installation of a production platform, offshore western Libya within the development project of the Wafa and Structure C fields in permit NC-41 operated by Eni with a 50% interest. The total value of the contract is estimated at euro 620 million, of which Saipem’s share is euro 420 million and includes project management, engineering, procurement, fabrication, transportation and installation, hook-up and commissioning, start-up and six month of operational assistance.

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 Antitrust Authority of the European Commission. Bouygues Offshore is a French company leader in the field of engineering for the oil industry. The cash offer price of euro 60.08 per share corresponds to an evaluation of the company at about euro 1 billion. Following approvals from the French and USA market authorities Saipem launched a public offer for the remaining shares held by the public at the same price paid to Bouygues Construction for its majority interest. This public offer 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%). The public offer on the US market is still underway. This transaction represents the largest cross-border acquisition in Europe in the oilfield services sector. The combination of Saipem’s recognised construction capabilities supported by technologically advanced vessels, and Bouygues Offshore’s powerful engineering and project management expertise will create a new, truly worldwide group with a superior competitive positioning in the provision of turnkey projects to the oil industry. With this acquisition Saipem reaches a superior competitive positioning in the provision of EPIC services to the oil industry, with a particular focus on activities 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, which is listed on the Paris and New York Stock Exchanges, is a leader in the design, construction, installation and management of 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 activities are Europe and Africa. Bouygues Offshore has approximately 2,500 engineers within its workforce, and generated revenues of euro 1 billion and net income of euro 46 million in 2001. On September 9, 2002, Bouygues Offshore announced first half 2002 results, with a 12% increase in net sales over the same period of 2001 and an order backlog of euro 1.1 billion.

RESEARCH AND DEVELOPMENT

In the first half of 2002, Eni invested euro 86 million in research and development (euro 96 million in the first half of 2001).

In the Exploration and Production segment, work was directed to: (i) the reduction of mineral risk, in particular through the development of the Krig Tree software for improving geostatic studies; (ii) the reduction of operating costs, in particular through the assurance flow technique in flowlines and a new kind of drilling head; (iii) the reduction of time necessary for reaching the production phase in oil fields, in particular through the development of the SCREAM software for a faster access to geo-mineral data.

In the Refining and Marketing segment, work was directed to the improvement of gasoline (reduction in aromatic content) and gasoil (reduction of sulfur content) quality. A new kind of lubricant base was developed for light engines which represents an innovative step in fuel economy.

In the Petrochemical segment, work was directed to the formulation of a new catalyst for polyethylene and to the development of new products, in particular a linear polyethylene for cast stretch film, a high density polyethylene for large container blowing, an expandable polystyrene for insulating foundations, expandable polystyrene for packaging with improved processability, styrene-isoprene elastomers for packaging adhesives.

The basic planning phase of the pilot plant employing the Eni Slurry Technology for the hydroconversion of refining residues and of heavy crudes without by-production of fuel oil was completed and the plant is now in the detailed design phase.

Within the project for natural gas enhancement, the testing phase for the catalyst and reactor employing the Fischer-Tropsch technology for middle distillate conversion was completed at the pilot plant at the Sannazzaro refinery. Laboratory development for the production of hydrogen with segregation of carbon monoxide was started.

Work continued in the area of environmental protection and development of renewable energy sources. In the area of photovoltaic energy, in the second half of 2002 an improvement of the thin film technology will come on line. As concerns environmental protection, a mathematic model was developed simulating multiphase flows in soils contaminated by hydrocarbons and solvents, while a project was defined for a pilot plant for the wet reduction of chloridized pollutants from combustion fumes.

During the six-month period, 17 applications for patents were filed in Italy (32 in the first half of 2001).

SUBSEQUENT EVENTS

Relevant subsequent events concerning operations are found in the operating review.

MANAGEMENT’S EXPECTATIONS OF OPERATIONS

Trends in 2002 of main outside variables that influence Eni’s results of operations are indicated below:

• worldwide demand for oil is expected to recover in the second half of 2002 (up 1%, over the second half of 2001) in line with the expected recovery of world economy, in particular in the USA. The increase in demand is expected to be of 0.3 percentage point in 2002. The market situation and the persisting tension in the Middle East should support the price of oil in the second half of 2002. The price of oil is expected to reach about 26.6 dollars/barrel, representing a 19% increase as compared to the second half of 2001. In 2002, then, the price of oil would average about 24.9 dollars/barrel (24.46 in 2001);

• demand for natural gas in Italy is expected to increase by 2% compared to 2001, due to increased consumption for the production of electricity and for industrial uses;

• refining margins are expected to decline compared to 2001. The recovery in the demand for refined products expected in the second half of the year will not to be sufficient to offset the weak refined product prices as compared to oil prices registered in the early months of the year, a situation that led refining margins to their lowest levels in the past ten years;

• demand for petrochemical products is expected to increase slightly in the second half of 2002 in line with the recovery of world economy. The marked increase in demand and sales of the first half of 2002 was mainly related to the rebuilding of stocks of processing companies. The increase in prices will be offset in part by the expected increase in prices of oil-based feedstocks, so that the improvement in margins will not be able to offset the decline in margins recorded in the first quarter of 2002. On an annual basis margins are expected to remain on lower levels than in 2001 but with a general improving trend.

42

The following are the forecasts for the production and sales performance of Eni’s main activities in 2002:

• daily production of hydrocarbons, before the effect of the rationalization of the portfolio of mineral assets, is forecasted to grow by approximately 8% compared to 2001 despite the effects of production cuts decided by OPEC, due to production increases in Norway, the United Kingdom, Venezuela, Kazakhstan, Egypt, Nigeria, and Italy (oil), as well as new fields coming on line in particular in Algeria, Iran, the United States and Pakistan;

• volumes of natural gas sold in primary distribution in Italy, assuming that temperatures are normal for the rest of the year, are expected to decline by approximately 8% compared to 2001, due to the gradual alignment of Eni’s market share with the regulatory limits; this decline will affect in particular sales to wholesalers and industries. Volumes sold in Europe destined to Italy are expected to more than double (up 353% in the first half of 2002) due to the reaching of full supplies of some transmission contracts to Italian importers. Volumes transported on behalf of third parties in Italy are expected to increase by about 70%, also in relation to the increase in Eni’s sales in Europe destined to Italy;

• electricity production sold is forecasted at approximately 5,000 gigawatthour, roughly stable as compared to 2001; volumes of purchased electricity sold on the market are forecasted at approximately 1,500 gigawatthour;

• total refinery processing intake on wholly owned refineries is expected to remain stable due to the slight increase in processing on account of third parties which offset the decline of processing on own account. The new processing mix reflects the sale to Tamoil of processing capacity for 1.6 million tonnes/year that took place in 2001. The overall balanced capacity utilization rate of wholly owned refineries is expected to remain stable (97% in 2001).

In 2002 capital expenditure is expected to amount to approximately euro 8 billion; about 86% of these investments will be made in the Exploration and Production and Gas & Power divisions.

Accounting and Reporting Policies

BASIS OF PRESENTATION

The unaudited interim condensed consolidated financial statements of Eni included herein have been prepared in accordance with the criteria determined by the Commissione Nazionale per le Società e la Borsa (Consob) in its regulation included in decision No. 11971 of May 14, 1999, as amended by decision No. 12475 of April 6, 2000.

Eni’s consolidated financial statements contained herein are expressed in millions of euro, keeping into account their importance.

In the income statement and balance sheet tables comparative amounts at December 31, 2001 and June 30, 2001 are presented for each item, aggregated whenever needed according to the tables used. Income statement items reflect comparisons of the current six months with those reported at June 30, 2001, while comparisons of balance sheet items reflect amounts as reported at December 31, 2001. Relevant changes are included in the “Operating Review” included in the Report of the Directors.

The interim consolidated financial statements include the statutory accounts of Eni SpA and all Italian and foreign companies included in the scope of consolidation.

Consolidation criteria are unchanged from the previous year.

The most important changes in the scope of consolidation that have taken place in the first half of 2002 concern the inclusion in consolidation of Polimeri Europa SpA, which caused the inclusion of other 4 companies that are consolidated on a line by line basis.

The accounting and reporting policies applied to the unaudited interim condensed consolidated financial statements for the six months ended June 30, 2002 are consistent with those applied for the preparation of the consolidated financial statements for the year ended December 31, 2001, to which reference should be made.

The consolidated report on the first half of 2002 underwent a limited review by PricewaterhouseCoopers SpA. A limited review implies significantly less work as compared to a full audit performed according to the regulations governing external audits.

As concerns Eni SpA’s accounts only the tables are presented as provided for by art. 81 line 2 of the above mentioned Consob regulation.

TRANSLATION OF EURO AMOUNTS INTO U.S. DOLLAR AMOUNT

The unaudited interim condensed consolidated financial statements are stated in euro. The translation of euro amounts into U.S. dollars is 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 June 28, 2002, which was 0.9856 USD to euro 1.00. The convenience translations should not be construed as representations of what 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.

Intangible assets of euro 2,501 million concern specifically the acquisition of natural gas transportation rights from Algeria (euro 759 million), exploration permits (euro 387 million), concessions, licenses, trademarks and similar rights (euro 362 million), and the difference between the purchase price of consolidated investments and the fair value of corresponding net equity (euro 345 million), related in particular to Lasmo Plc (euro 260 million), Companhia São Paulo de Petroleo SA, now Agip Distribuidora SA (euro 43 million) and Inversora de Gas Cuyana SA (euro 22 million).

Investments for euro 528 million related primarily to costs for exploration activities for euro 442 million (euro 370 million in the first half of 2001), of which euro 428 million was amortized in full in the period incurred.

Amortization amounted to euro 645 million and related essentially to exploration costs for euro 492 million (euro 383 million in the first half of 2001).

Capital expenditures of euro 2,932 million (euro 2,290 million in the corresponding period of 2001) relate primarily to the Exploration and Production segment (euro 2,222 million), Gas & Power segment (euro 289 million), Refining and Marketing segment (euro 175 million) and Oilfield Services and Engineering segment (euro 105 million, of which euro 92 million relates to construction and drilling activity). Additional information about capital expenditures is included in the “Operating Review” of the Report of the Directors.

Changes in scope of consolidation for euro 544 million were primarily due to the inclusion in consolidation of Polimeri Europa SpA (euro 538 million).

Other changes of euro 158 million relate primarily to the sale of assets for euro 190 million, writedowns of euro 118 million made by the Exploration and Production (euro 85 million) and the Refining and Marketing segment (euro 31 million) and the recording to fixed assets of the difference between the purchase price and the corresponding net equity of the further 50% of European Marine Contractors Ltd (euro 139 million).

Monetary revaluations included in the gross and net value of fixed assets amount to euro 1,277 and 94 million respectively (euro 1,295 and 112 million at December 31, 2001).

At June 30, 2002 fixed assets have been pledged for euro 463 million primarily as collateral on debt incurred by Eni (euro 240 million at December 31, 2001). The increase of euro 223 million was due essentially to the inclusion in consolidation of Polimeri Europa SpA (euro 219 million).

Treasury shares		2,068		2,302
		7,328		6,798		1,517

Investments for euro 2,610 million decreased by euro 402 million. Such decrease was due primarily to the cancellation of investments in Polimeri Europa SpA (euro 257 million) following its inclusion in consolidation, to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 101 million), to the net reductions in value of investments accounted for under the equity method or cost method (euro 78 million), among others Blu SpA (euro 25 million), Distribuidora de Gas del Centro SA (euro 23 million) and Galp Energia SGPS SA (euro 18 million). Such decrease has been partially offset by new acquisitions (euro 73 million), in particular the acquisition of Ages Pisa SpA (euro 49 million).

Receivables for euro 1,573 million concern loans made for operating purpose and decreased by euro 342 million. Such decrease was due primarily to the inclusion in consolidation of Polimeri Europa SpA (euro 216 million) and to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 185 million), such decrease was partially offset by the net change in receivables during the period (euro 59 million). Receivables are granted primarily by the Gas & Power segment (euro 725 million) and the Exploration and Production segment (euro 717 million). Repayment of a portion of such loans for euro 66 million is contingent upon the outcome of financed activities (euro 267 million at December 31, 2001). Some amounts loaned may become capital contributions toward investments. Receivables due within twelve months amount to euro 59 million (euro 277 million at December 31, 2001), those due beyond twelve months amount to euro 1,514 million, of these euro 909 million are due beyond five years (euro 1,638 and 526 million at December 31, 2001, respectively).

Securities for euro 313 million decreased by euro 20 million. This decrease was due primarily to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 19 million). Securities for euro 21 million are related to operations (the same amount at December 31, 2001).

Treasury shares for euro 2,302 million (euro 2,068 at December 2001) and consist of 169,450,490 ordinary shares nominal value 1 euro owned by Eni SpA (154,380,826 ordinary shares nominal value 1 euro, as of December 31, 2001). Such shares are valued at cost and have been repurchased to increase shareholder’s value in accordance with the decision of Eni shareholders’ meeting of June 6, 2000 and June 1, 2001.

Inventories are recorded net of the inventory valuation reserve of euro 124 million (euro 159 million at December 31, 2001).

Crude oil and petroleum products inventories for euro 591 million and natural gas inventories for euro 39 million represent certain minimum quantities (“compulsory stock”) required by law (euro 548 and 39 million at December 31, 2001 respectively), while natural gas inventories valued at euro 389 million, are used to satisfy peak demand (euro 362 million at December 31, 2001).

Receivables are net of the allowance for doubtful accounts of euro 840 million (euro 1,059 million at December 31, 2001).

The euro 1,564 million decrease in trade receivables relates in particular to the Gas & Power segment and is due primarily to the seasonality in demand for natural gas (euro 1,921 million), such decrease has been partially offset by the consolidation of Polimeri Europa SpA (euro 538 million).

Financing receivables of euro 1,659 million include amounts due to Eni’s non-financing subsidiaries from banks for investing purposes and deposit in escrow euro 545 million (euro 17 million at December 31, 2001) among others euro 527 million concern a deposit in escrow of Saipem SpA in order to guarantee the acquisition of a French company Bouygues Offshore, loans made for operating purposes for euro 891 million (euro 944 million at December 31, 2001) and amounts due to Eni’s financing subsidiaries from banks and other financing institutions for euro 223 million (euro 57 million at December 31, 2001).

Other receivables for euro 3,981 million include primarily accounts receivable from Italian and foreign tax authorities (euro 1,897 million), accounts receivable from joint venture operators related to exploration and production activities (euro 621 million).

During 2001 such assets have been transferred to Snam Rete Gas SpA.

The “Income tax liabilities” reserve for euro 3,258 million includes net deferred tax liabilities, current taxes accrued in the six month period, as well as expected liabilities for the settlement of tax proceedings. The euro 637 million increase is primarily due to the net provisions of the period (euro 691 million), and the set-off, for each company, of tax assets and deferred tax liabilities (euro 256 million). Such increase has been partially offset by net exchange differences due to the translation of financial statements prepared in foreign currencies (euro 217 million).

The “Site restoration and abandonment” reserve of euro 1,914 represents primarily the estimated costs for well-plugging, abandonment and site restoration (euro 1,853 million).

The “Environmental risks” reserve of euro 895 million increased by euro 91 million as a result of the incorporation of Pertusola Sud SpA (in liquidation) in Singea SpA (in liquidation) (euro 108 million).

The reserve for “Losses related to investments” of euro 264 million decreased by euro 120 million due to the incorporation of Pertusola Sud SpA (in liquidation) in Singea SpA (in liquidation) (euro 131 million).

Financial debt amounted to euro 12,203 million and decreased by euro 715 million primarily due to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 959 million). Such decrease was partially offset by the change in the scope of consolidation (euro 381 million, of which euro 306 million relates to Polimeri Europa SpA).

		6,246		5,957		12,203

Debt to tax authorities of euro 2,204 million decreased by euro 181 million due to the decrease in income taxes and other tax liabilities (euro 861 million) partially offset by the increase in excise tax and custom duties (euro 680 million) following the payment made by the Refining and Marketing Segment and Gas & Power segment on July 2002 of excise tax and custom duties due for June 2002 (excise tax and custom duties due for the first half of December are paid in the same month of December).

Other debts of euro 3,510 million are related to investment activities for euro 926 million (euro 802 million at December 31, 2001).

Commitments concerning derivative contracts for euro 9,939 million (euro 8,148 million at December 31, 2001) concern activities aimed at reducing market risk from changes in interest rates, foreign exchange rates and commodity prices. The increase of euro 1,791 million, is due primarily: (i) to the increase in the number of interest derivatives (euro 991 million) entered into by Enifin SpA in order to hedge financial debt granted to Snam Rete Gas SpA; (ii) to the increase in the number of contracts entered into by Enifin in order to hedge foreign exchange rate risk (euro 899 million), following the increase of derivatives transactions on behalf of all Eni group companies. Eni’s operating subsidiaries are required to reduce foreign exchange rate risk to a minimum level. Eni provides guidelines to determine the maximum level of foreign exchange rate and interest rate risks that can be assumed by Eni’s finance companies and criteria of 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 maximum tolerable level of risk adopted by such companies is significantly lower 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 the maximum tolerable risk level, the portfolio of financial instruments and market conditions. Eni does not enter into derivative transactions on a speculative basis.

Obligations for purchase and sale of fixed assets of euro 593 million (euro 296 million as of December 31, 2001) concern investments for euro 439 million (euro 146 million as of December 31, 2001) and securities for euro 154 million (euro 150 million as of December 31, 2001). The increase for euro 293 million concern obligations for purchase of investments in the German companies GVS (Gasversorgung Süddeutschland GmbH, euro 344 million) and EBS (Erdgas Beteiligungsgesellschaft Sud), by the Gas & Power segment. Such increase was partially offset by satisfied obligations (euro 49 million). Obligations relating to marketable securities concern the placement on the market of securities managed by Sofid Sim SpA. This company sold Italian Government bonds to investors, primarily employees, and simultaneously entered into interest rate swaps with such investors wherein it receives the rate of interest on such Italian Government bonds and pays a floating rate of interest linked to Euribor. Such investors may sell their securities back to Sofid Sim SpA at any time for par value plus related interest with the simultaneous cancellation of the related swaps. Against the commitment related to interest rate swaps Eni entered into derivatives included in those mentioned above, for which Eni receives a variable rate more profitable than the one reknown by the shareholders.

Commitments of euro 520 million (euro 508 million as of December 31, 2001) are primarily related to: (i) agreements between EniChem SpA and various government entities, employee and trade groups whereby EniChem SpA has committed to invest approximately euro 272 million (the same amount as of December 31, 2001) in order to further develop the chemical segment and protect the environment with respect to the Porto Marghera plant; (ii) a memorandum of intent signed

61

with the Basilicata Region whereby Eni has agreed to invest, also on account of Enterprise SpA, euro 217 million in the future in connection with Eni’s development plan of oil fields in Val d’Agri (euro 222 million as of December 31, 2001).

Risks of euro 882 million (euro 905 million as of December 31, 2001) are primarily associated with: (i) contractual assurances given to acquirors of certain investments and businesses of Eni for euro 394 million (euro 508 million as of December 31, 2001). The decrease for euro 114 million concern satisfied obligations, in particular the obligation of Singea SpA (in liquidation) for the disposal of Porto Vesme and San Gavino integrated plant (euro 96 million); (ii) potential risks associated with the value of assets of third parties under the custody of Eni for euro 280 million (euro 159 million as of December 31, 2001); (iii) environmental proceedings for euro 136 million (the same amount as of December 31, 2001); (iv) tax proceedings for euro 48 million (the same amount as of December 31, 2001). Environmental risks include the action taken by the Minister of Environment against EniChem SpA in 1992 (euro 135 million) that is commented under the following item “Legal Proceedings”.

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 reserves, 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 an amount receivable of euro 182 million 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), now 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 judgement.

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. Conclusions are being defined for this arbitration proceeding. Defendants brought counterclaims. In December 2000, an agreement was reached through which Montedison accepted EniChem’s claim of euro 41 million and paid said amount on December 22, 2000. Arbitration is still pending for all environmental issues.

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 of 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 appeals 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 a 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.

In August 2000, the Ministry of Finance of Kazakhstan sent Agip Karachaganak a formal assessment that claims that the company understated its income for 1998 and 1999 by euro 58 million. The amount relates to the non deductibility of overhead costs considered as cost recovery and to a different criterion for the deduction of some other costs. During the first half of 2001 Eni signed a protocol with the tax authorities of Kazakhstan which reduces the amount under assessment to euro 12 million. Appeals are however underway according to local laws.

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 net of 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 against this decree with the jurisdictional bodies. At the same time an official interpretation has been requested to the Ministry of Finance and Economy. With a decision of May 29, 2001, the Ministry confirmed that this additional excise tax is not applicable. 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 the jurisdiction of the Administrative court did not apply to this case. In case the Region should request payment, Snam will proceed with the relevant Court. 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 that was conferred to Enimont 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.

In 1997, a preliminary hearing was held before the Court of Venice concerning the criminal charges brought by the Venice public prosecutor against 28 persons, including 12 former and current managers of Eni1, for alleged mismanagement of the Porto Marghera plant starting in the 1970s until 1995 and for the alleged pollution 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 30, 2002 the judgment was deposited. The decision can still be appealed by the State attorney.

In 2000, the public prosecutor of Brindisi started a criminal action against 68 persons who are 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 are 20 former employees or managers of EniChem SpA who managed these plants from 1983 to 1993. This proceeding is still at the preliminary stage and is aimed at ascertaining any responsibility related to illnesses suffered by workers employed in said plants. A request was filed for further investigation.

In 2000, the public prosecutor of Gela started an investigation on prohibited emissions from AgipPetroli SpA’s refinery (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 1988. The investigation brought an action against some former managers of the refinery for events registered from 1997 to date. The Municipality of Gela will act as civil party and requested the payment of compensatory damage from AgipPetroli for a total of euro 878 million.

Under Regional Law No. 2 of March 26, 2002, the Sicilia Region introduced an environmental tax on owners of primary pipelines in Sicilia (i.e. pipelines operating at a maximum pressure of over 24 bar). The purpose of the tax is “to finance investments aimed at reducing and preventing potential environmental damage caused by pipelines containing natural

(1) In the description of this proceeding Eni includes Eni SpA, EniChem SpA and its subsidiaries.

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 for 2002 totals approximately euro 97 million. In view of the compulsory nature of this environmental tax, Snam Rete Gas has paid the due instalments within the established time limits (April to August 2002). On the strenght of authoritative legal opinions and fiscal advice, Snam Rete Gas maintains that this tax is illegitimate for a number of reasons and lodged claims with the Sicilia Region requesting reimbursement of the sums paid, as a preliminary step for legal proceedings, and intimating their entailment considering that reimbursement is due. On July 30, 2002, Snam Rete Gas lodged a complaint 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. As the Sicilia Region rejected the request for reimbursement of the first instalment, Snam Rete Gas will lodge an appeal with the Provincial Tax Commission of Palermo aimed at obtaining a definitive and rapid decision ascertaining the legitimacy of the tax and at the same time will lodge an appeal with the Regional Administrative Court of Lombardia to obtain immediate recognition in tariffs of a cost that is due and has effectively been incurred by the company.

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

In March 1999, the Antitrust Authority concluded its investigation and fined Snam SpA euro 2 million for allegedly abusing its dominant position in the market for the transportation and distribution of natural gas and ordered a review of certain of Snam’s business 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, this Court granted the suspension of the decision. The Antitrust Authority did not appeal this decision. The proceeding is still pending.

With a 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 for the period May 1 to September 30, 2001 was accepted only in part, the Antitrust Authority start an inquiry on Snam and Snam Rete Gas SpA to establish if they abused their dominant position when they assigned transport capacity at the import point (in this case Passo Gries, for the period May-June 2001 and thermal year 2001-2002). On July 23, 2002 the Antitrust Authority has transmitted the preliminary inquiry which shows that abuse of dominant position and prejudice to competition cannot be fully ruled out. Eni is allowed to present a defense memorandum and request a hearing at the Authority. The inquiry is expected to be closed by the end of September, while the final decision of the Authority on the proceeding, based on the information collected by the end of September, is expected to be made public in November 2002.

On August 28, 2000, Enirisorse SpA (in liquidation) now Singea SpA (in liquidation) and Zincocalabra SpA signed an agreement for the sale of the whole share capital of Pertusola Sud SpA (in liquidation), now merged in Singea SpA (in liquidation). This agreement was filed with the European Commission within the procedure for monitoring the liquidation of Enirisorse’s assets in the non ferrous metallurgy business, as per decision 98/212/CE of April 16, 1997. With a letter dated September 26, 2000, the Commission requested information to the Italian Government for appraising the compatibility of this agreement with said decision. On February 13, 2001, the Commission informed the Italian Government that it started the procedure as per article 88 of the Union Treaty for alleged state aid in favor of Pertusola Sud. This procedure is started in the context of the above mentioned decision for the following reasons: (i) aid given to Pertusola Sud in relation to the decision could have been given unlawfully; (ii) funds provided to Pertusola Sud by Singea in liquidation could be considered as state aid, and in this case are not compatible with the single market; (iii) funds provided by Singea to Pertusola Sud for environmental charges may represent state aid, and if this is the case they are not compatible with the single market. On April 4, 2001, the Italian Government presented its observations to the Commission informing it that “Zincocalabra is no longer interested in pursuing an investment with deadlines prolonged by the ongoing procedure”. In May 2001, the Commission opened a procedure against the Italian Government, which in turn on July 25 transmitted to Enirisorse all the observations sent to the Commission for the preparation of an answer. In October 2001 the Italian Government presented its observations to the Commission. The Commission may present its decision before the end of 2002. If the final decision is unfavorable, Pertusola Sud shall have to return to Enirisorse the funds in question that are considered unlawful state aid. On February 1, 2002 Pertusola Sud was merged in Singea, therefore in case of an unfavorable decision Pertusola Sud should reimburse itself Singea. This decision may be appealed according to European procedures.

With a decision presented on June 5, 2001 the Antitrust Authority started an inquiry against AgipPetroli, Atriplex and other companies for alleged limitations to competition within the tenders offered by public transportation companies in the

64

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 expression of a more general arrangement among companies for dividing between them the mentioned fuel supplies. The proceeding shall be closed before October 11, 2002.

Other commitments and risks not included in the balance sheet

In order to satisfy expected demand for natural gas in Italy in the medium and long-term, Eni has entered into certain long-term gas supply agreements which currently have an average unexpired duration of approximately 20 years. Such agreements, which contain take-or-pay provisions, will enable Eni to purchase an aggregate of approximately 1,095 billion cubic meters of natural gas. Under such agreements, the prices to be paid for the gas are periodically revised based on the market price for certain petroleum products. In connection with its supply contracts, Eni is also a party to long-term contracts with third parties for the transport of natural gas from the delivery point of foreign suppliers to Italy, these contracts generally contain ship-or-pay provisions. Eni also owns transmission rights on pipelines outside Italy and signed contracts with third parties for the transport of purchased natural gas to Italy. Historically, Eni’s purchasing and transmission practices have been such that take-or-pay or ship-or-pay provisions have never been invoked. On June 20, 2000, Decree No. 164 of May 23, 2000 issued by the Council of Ministers to implement the European Directive on natural gas into Italian legislation became effective. Such decree accelerated the opening of the market by allowing the entry of several operators in the Italian marketplace, and at the same time introduce ceilings to each operator’s market share and provides for the legal separation of some activities, while protecting take-or-pay contracts and the principle of reciprocity as specified by the European Directive. In order to remain within the limits set for the input of natural gas into the Italian system and with the aim of not being subjected to take-or-pay constraints, Eni sold the natural gas volumes it deemed exceeding outside Italy by signing multi-annual agreements with other operators which will sell such volumes on the Italian market.

Non-quantifiable risks related to contractual assurances given to acquirors of investments against certain unforeseeable liabilities attributable to tax, state welfare contributions and environmental matters applicable to periods during which such investments were owned by Eni. Eni believes such matters will not have a material adverse effect on its consolidated financial statements.

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 management, 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 Eni’s consolidated financial statements as a result of its compliance with such laws and regulations, there can be no assurance that there will not be a material adverse impact on Eni’s consolidated financial statements due to: (i) the possibility of as yet unknown contamination; (ii) the results of the on-going surveys and the other possible effects of statements required by 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.

Taxes on:
Italian subsidiaries		1,547		593
Foreign subsidiaries		1,196		1,229
		2,743		1,822

Income taxes of Italian companies for euro 593 million, decrease of euro 954 million. Such decrease was due primarily to the lower taxable income (euro 591 million), to the tax benefit due to the application of law No. 342/2000 (euro 182 million), and the net effect of the release of anticipated depreciation reserve in accordance with law 498/2001 (euro 93 million).

Income taxes were calculated applying the related estimated annual effective tax rate to income before taxes of each consolidated company for the period, adjusted for the fiscal effects deriving from significant income or expenses subject to separate fiscal regimes, which are recorded in the period when they actually take place.

Income taxes affected “Income before income taxes” for the period at the rate of 41% compared with a statutory tax rate of 41.9% calculated by applying a 36% tax rate (Irpeg) to income before taxes and a 4.25% tax rate (Irap) to the net value of production as provided for by Italian laws.

The analysis of the difference between the theoretical and the actual tax rate is the following:

				(%)
	First half			First half
	2001			2002
Statutory tax rate		41.1			41.9
Items increasing (decreasing) statutory tax rate:
- higher foreign subsidiaries tax rate		4.3			6.0
- permanent differences		0.9			(0.3	)
- tax benefit due to the application of favorable tax laws		(1.7	)		(2.1	)
- tax benefit on gains from disposals due to the application of law No. 342/2000		(1.8	)		(4.1	)
- other		0.2			(0.4	)
		1.9			(0.9	)
		43.0			41.0

20) Earnings per share

Basic earnings per share is calculated by dividing “Net Income”, excluding minority interest, by the weighted-average number of shares issued and outstanding during each period, excluding treasury shares.

In order to compare basic earnings per share in the two periods presented, the number of shares issued through stock grants made from July 1, 2001 to June 30, 2002 has been added to the weighted-average number of shares outstanding in the first half of 2001; based on this criterion, the weighted-average number of shares outstanding was 3,940,892,301 and 3,841,775,430, in the first half of 2001 and 2002, respectively.

The dilutive effect on Eni’s basic earnings per share produced when potential ordinary shares will be converted into ordinary shares is not significant. At present, the only outstanding dilutive potential ordinary shares are the shares offered for no consideration; in regard to stock options offered to employees the conditions for exercise have not occurred.

23) Average number of employees

The average number of employees of the companies included in consolidation by type of consolidation is as follows:

	Companies consolidated				Companies consolidated
	on line-by-line basis				on a proportional basis
	First half 2001		First half 2002		First half 2001		First half 2002
Senior managers		1,659		1,469		5		3

Workers		27,404		28,242		245		614
		70,056		70,959		578		966

The average number of employees is calculated as half of the total of the number of employees at the beginning and at the end of the period. Employees of companies consolidated on a proportional basis are recorded according to the control percentage.

24) Adjustment of the unaudited interim consolidated financial statements prepared under Italian GAAP to U.S. GAAP

In accordance with the criteria adopted in Eni’s Annual Report, in application of the regulations of the Securities and Exchange Commission (SEC), the following information is necessary to adjust the Italian consolidated report for the first half of 2002 to generally accepted accounting principles in the USA or U.S. GAAP.

a) Accounts reclassified according to International GAAP

The items of Eni’s consolidated balance sheet have been classified according to the criterion of decreasing liquidity, while those of the reclassified income statement are substantially the same as those included in the Italian statutory accounts, except for some aggregations.

At the bottom of each account the reader finds the content of the items which differ from those calculated according to the Italian standards if those items are not discussed in the notes to the statutory accounts.

The changes from the previous period are illustrated in the notes to the statutory accounts.

b) Summary of significant differences between Italian GAAP and U.S. GAAP

The Company’s interim financial statements have been prepared in accordance with Italian GAAP, which differ in certain respects from U.S. GAAP.

The significant differences between the two principles are the same as indicated in the 2001 consolidated financial statements. One exception is represented by the evaluation and recording criteria provided for by Accounting Standard No. 141 “Business Combination” (SFAS 141) and No. 142 “Goodwill and other intangible assets” (SFAS 142). SFAS 141 and 142 are effective for the accounting periods starting after December 15, 2001.

According to the new standards, the goodwill and the intangible assets with an indefinited useful life can not be amortizated; these assets are subject to a yearly evaluation in order to define the relevant writedown if needed. The maximum amortization limit of forty years has been eliminated for intangible assets with fixed useful life.

According to the 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.

The effect of the difference between these two criteria is recorded in item c) below.

d) Additional financial statement disclosures required by U.S. GAAP

Stock Compensation

With the aim of improving motivation and loyalty of Eni managers, Eni approved plans for the grant of Eni shares and stock option to Eni manager. The general provisions of this plans are set forth in the “Directors’ Report” and relevant costs are recorded in income for U.S. GAAP purposes. The disclosures requirements of SFAS No. 123, “Accounting for Stock-Based Compensation” (SFAS 123) are included below. As permitted under SFAS 123, Eni has adopted APB 25 and related interpretations in accounting for shares and options issued to employees in its reconciliation to U.S. GAAP. The application of SFAS 123 instead of APB 25 does not result in a significant difference.

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 Asset 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 the associated asset retirement costs. The statement requires that the fair value of a liability for an 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. The discount associated with the liability is accreted into income over the related asset’s 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 accumulated 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 the conversion of finance leases into operating 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 superseded 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 the next period such value can be modified to take into consideration new estimates and the increasing related to time. This statement is effective starting after December 31, 2002. Eni shall apply it beginning in 2003.

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.
