highlights

In the first half of 2003 Eni reported net income of euro 3,090 million, with an increase of euro 829 million over the first half of 2002, up 37%, due mainly to a positive operating performance (up euro 537 million) related to an increase in prices and margins, in hydrocarbon production sold and in natural gas volumes sold, as well as cost reductions, whose effects were offset by the appreciation of the euro over the dollar (up 23.1%) and the recording of higher asset writedowns. Before non-recurring items net income increased by 15%

In the first half of 2003 daily hydrocarbon production amounted to over one and a half million barrels of oil equivalent (boe), an increase of 5% over the first half of 2002, due to the purchase of the Norwegian company Fortum Petroleum, start-ups of fields and production growth in areas of consolidated presence. Production growth is in line with Enis medium term plans which set a production target of over 1.8 million boe/day by 2006 achievable by leveraging on the development of assets in portfolio

In July exports of oil produced in the Karachaganak field (Eni is co-operator with a 32.5% interest) to Western markets started after the coming on stream of a plant for the treatment of liquids (Karachaganak Processing Center), the most important plant of this kind ever built in the world, and of infrastructure connecting it to the Caspian Pipeline (Eni holds the right to transport up to 3 million tonnes/year through this pipeline belonging to the Caspian Pipeline Consortium) that links with the Russian terminal at Novorossiysk on the Black Sea. Before year end production from the field will increase from the present 220,000 boe/day to 380,000 (65,000 and 110,000 respectively net to Eni)

The closing in July of the purchase of 50% of the Spanish company Unión Fenosa Gas and the entry into operations in February of the Blue Stream gasline for supplies to the Turkish market are part of Enis strategy of expanding in European markets with interesting growth and profitability prospects, targeting sales of about 44 billion cubic meters of natural gas by 2006

In July power production started at the first of the three combined cycle units of the new Ferrera Erbognone power station. The gas fired power station will start full operations in 2004 with a capacity of 1,000 megawatts and a production of about 7 gigawatthours/year. The plan for expanding Enis power production capacity, which targets an installed capacity of 6,000 megawatts, was started in Brindisi (a new 1,170 megawatts power station) and Mantova (780 megawatts of incremental capacity) and continues in Ravenna (780 megawatts of incremental capacity)

Enis net income for the first half of 2003 totaled euro 3,090 million, an increase of euro 829 million over the first half of 2002, up 36.7%, due essentially to a positive operating performance (up euro 537 million) related to an increase in prices and margins, an increase in hydrocarbon production sold and in natural gas volumes

SEASONALITY

Enis 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.

sold, as well as cost reductions whose effects were offset in part by the appreciation of the euro over the dollar (up 23.1%), and higher asset writedowns. The increase in net income was also caused by the recording of higher net extraordinary income of euro 248 million, related in particular to the settlement of a dispute with Edison SpA concerning the Enimont joint venture (euro 200 million) and the decline in the share of net income attributed to minorities (euro 87 million) resulting from the tender offer on Italgas shares. These positive factors were partly offset by higher income taxes (euro 118 million).

In the first half of 2003, streamlining and efficiency improvement continued and allowed cost savings amounting to euro 228 million (on a constant exchange rate basis), which offset almost entirely salary increases and the effects of inflation.

Enis operating income for the first half of 2003 totaled euro 5,112 million, an increase of euro 537 million over the first half of 2002, up 11.7%, due to increases recorded by:

| - | the Exploration & Production segment (euro 395 million,
up 15.7%) related essentially to higher international oil prices in
dollars (Brent, up 24.6%) and higher hydrocarbon production sold (11.2
million boe, up 4.4%), whose effects were offset in part by the
appreciation of the euro over the dollar and by the recording of
writedowns of euro 129 million related mainly to unproved property
(euro 85 million in the first half of 2002); |
| --- | --- |
| - | the Refining &
Marketing segment (euro 203 million, up 166.4%) essentially due to an
increase in refining margins (Brent margin was up 2.52 dollar/barrel),
whose effects were offset in part by the appreciation of the euro over
the dollar, and in margins on distribution in Italy and Europe; |
| - | the
Gas & Power segment (euro 65 million, up 3.2%) related essentially to
increased natural gas volumes sold (up 5.1%) and margins, also related
to the appreciation of the euro over the dollar. |

As compared to 2002, in 2003 Enis activities have been grouped differently:

| - | Syndial (former EniChem) was included in the Other Activities
segment, which includes all Eni companies not included in specific
segments (such as, among others, EniData, Sieco, Tecnomare,
EniTecnologie, Eni Corporate University, AGI); |
| --- | --- |
| - | the new Corporate
and financial companies segment was created, which includes Eni
Corporate, Eni Servizi Amministrativi and the financial companies
formerly included in the Other Activities segment. |

In order to allow for a homogenous comparison, data for 2002 have been reclassified accordingly.

Enis net sales from operations (revenues) for the first half of 2003 amounted to euro 25,937 million, representing a euro 2,033 million increase over the first half of 2002, up 8.5%, due mainly to an increase in prices recorded in all of Enis business areas, an increase in hydrocarbon production sold and in natural gas volumes sold, as well as the revenues of Bouygues Offshore (now Saipem SA) acquired in July 2002 and higher activity levels in the Oilfield Services and Engineering segment. These effects were offset in part by the appreciation of the euro over the dollar.

Revenues generated by the Exploration & Production segment (euro 6,402 million) increased by euro 120 million, up 1.9%, due essentially to higher realized selling prices in dollars (oil up 27.2%; natural gas up 29.4%) and higher hydrocarbon production sold (11.2 million boe, up 4.4%), whose effects were partially offset by the appreciation of the euro over the dollar and by a decrease in storage tariffs (see Operating income below).

Revenues generated by the Gas & Power segment (euro 8,757 million) increased by euro 323 million, up 3.8%, due to higher prices for natural gas, and, at a lower extent, higher volumes sold in primary distribution (1.74 billion cubic meters, up 5.1%).

Revenues generated by the Refining & Marketing segment (euro 10,652 million) increased by euro 219 million, up 2.1%, essentially due to higher prices for petroleum products (the retail prices of gasoline and diesel fuel were up 11.6% and 14.5%, respectively), whose effects were offset in part by the appreciation of the euro over the dollar and by a decline in sales to Enis Petrochemical segment and to other oil companies (1.3 million tonnes).

Revenues generated by the Petrochemical segment (euro 2,351 million) increased by euro 112 million, up 5%, due mainly to the 15% increase in the average sale prices

Table of Contents

of products (especially olefins), whose effects where offset in part by lower volumes sold (down 8.3%).

Revenues generated by the Oilfield Services and Engineering segment (euro 2,687 million) increased by euro 753 million, up 38.9%, due to the purchase of Bouygues Offshore in the oilfield services area and higher activity levels.

Operating expenses for the first half of 2003 (euro 18,647 million) increased by euro 1,324 million compared to the first half of 2002, up 7.6%, essentially due to higher supply costs for natural gas and oil-based and petrochemical feedstocks, higher volumes supplied by natural gas primary distribution, the purchase of Bouygues Offshore and higher activity levels in the Oilfield Services and Engineering segment, whose effects were partially offset by the appreciation of the euro over the dollar and streamlining.

Payroll and related costs (euro 1,574 million) increased by euro 108 million, up 7.4%, due mainly to an increase in unit labor costs in Italy and the purchase of Bouygues Offshore.

Depreciation and amortization charges for the first half of 2003 (euro 2,592 million) increased by euro 51 million over the first half of 2002, up 2%, due in particular to higher asset writedowns (euro 154 million).

Amortization charges declined by euro 103 million due the decline registered in the Exploration & Production segment (euro 150 million) related to the appreciation of the euro over the dollar and in the Refining & Marketing segment (euro 26 million) related to the conferral of the Priolo refinery to Erg Raffinerie Mediterranee Srl (Enis interest 28%) finalized in October 2002. These declines were offset in part by the increase registered in the Gas & Power segment (euro 66 million) due to the writedown of the difference between the purchase cost of Italgas shares acquired and the underlying net book value (euro 45 million), and the coming onstream of new capital expenditure. The increase of amortization charges of euro 11 million in the Corporate and financial companies segment was due essentially to the integral amortization of the cost of the Eni Slurry Technology (EST) project and higher research costs.

Writedowns (euro 259 million) concerned essentially: (i) unproved property in the Exploration & Production segment (euro 129 million) in particular in Pakistan and the United Kingdom related to the process of determination of reserves; (ii) petrochemical plants (euro 83 million) in particular for the manufacture of polyethylene, elastomers and aromatics as a result of the impairment test.

Exploration & Production

Operating income in the first half of 2003 amounted to euro 2,910 million increasing by euro 395 million over the first half of 2002, up 15.7%, due mainly to: (i) an increase in realized selling prices in dollars (oil up 27.2%; natural gas up 29.4%); (ii) increased hydrocarbon production sold (up 11.2 million boe, up 4.4%); (iii) lower costs related to synergies obtained and streamlining. These positive factors were offset in part by: (i) the negative effect of the appreciation of the euro over the dollar (up 23.1%); (ii) lower operating income on storage activities (down euro 229 million) related mainly to the fact that in the first half of 2002 services rendered to primary distribution in the Gas & Power segment were recorded by applying tariffs in force before the reduction imposed by the Authority for electricity and gas with decision No. 49/2002, against which Eni filed a claim with the Regional Administrative Court of Lombardia requesting its cancellation; (iii) the recording of writedowns of mineral assets (euro 129 million) related mainly to unproved property in Pakistan and the United Kingdom, in connection with the determination of reserves (euro 85 million in the first half of 2002); (iv) the fact that in the second quarter of 2002 gains on the sale of assets were recorded for euro 42 million.

Gas & Power

Operating income in the first half of 2003 amounted to euro 2,068 million, increasing by euro 65 million over the first half of 2002, up 3.2%, due mainly to: (i) increased volumes sold in primary (up 1.74 billion cubic meters, up 5.1%) and secondary

Table of Contents

distribution in Italy (up 0.35 billion cubic meters, up 7.4%) and outside Italy (0.49 billion cubic meters, up 25.3%); (ii) higher margins in primary distribution, essentially in sales to thermoelectric users, related mainly to the effect of the appreciation of the euro over the dollar, offset in part by the renewal of contracts, and higher margins in secondary distribution; (iii) lower costs related to streamlining. These positive factors were offset in part by: (i) the writedown of the difference between the purchase cost of Italgas shares acquired and the underlying net book value (euro 45 million); (ii) the fact that in the second quarter of 2002 a euro 23 million net income was recorded as a balance of a euro 72 million income relating to tariff adjustments in secondary distribution resulting from decision No. 122/2002 of the Authority for electricity and gas and the payment of an environmental tax levied by the Sicilia Region (euro 32 million) and writedowns of assets in secondary distribution in Argentina (euro 17 million). The operating income of the electricity generation activity (euro 5 million) declined by euro 26 million, down 87%, due mainly to higher costs related to the planned maintenance standstill of the Taranto plant.

Operating income in the first half of 2003 amounted to euro 325 million, a euro 203 million increase over the first half of 2002, up 166.4%, due to: (i) increased results in refining activities related mainly to the recovery in refining margins (Brent margin was up 2.52 dollars/barrel), whose effects were offset in part by the appreciation of the euro over the dollar; (ii) higher operating results in marketing of refined products in Italy and in Europe related to increased margins; (iii) lower costs resulting from streamlining; (iv) the release of the Lifo reserve related to lower stocks (euro 25 million). These positive factors were offset in part by a decline in operating income from marketing of refined products in Brazil related to lower margins on LPG and the recording of environmental charges of euro 19 million.

Petrochemicals

In the first half of 2003 operating losses amounted to euro 51 million, with a euro 14 million increase (or 37.8%) on the first half of 2002 due to: (i) asset writedowns of euro 83 million, related in particular to plants for the manufacture of polyethylene, elastomers and aromatics as a result of the impairment test; (ii) a writedown of product inventories of euro 23 million to adjust them to expected sale prices (in the first quarter of 2002 inventories were revaluated for euro 28 million); (iii) lower volumes sold (down 8.3%). These negative factors were offset in part by: (i) an increase in margins related to an increase in sale prices (up 15%) higher than the increase in the cost in euro of petrochemical feedstocks (up 7.9%); (ii) lower costs related to streamlining.

Oilfield Services and Engineering

Operating income for the first half of 2003 totaled euro 139 million, of which euro 138 million related to oilfield services , with a euro 20 million decrease over the first half of 2002, down 12.6%. Oilfield services recorded a decrease in operating income of euro 37 million, in particular in Offshore construction due to the completion of the Blue Stream contract and the start of EPIC (Engineering, Procurement, Installation, Commissioning) contracts which do not foresee the use of vessels in their initial stages. These negative effects were offset in part by the contribution of Bouygues Offshore purchased in July 2002 (euro 35 million before the writedown of euro 21 million of the difference between purchase price and net equity not attributed to fixed assets) and the higher profitability of some contracts in the Onshore construction area. Engineering activities recorded an operating income amounting to euro 1 million as compared to an operating loss of euro 16 million in the first half of 2002. The euro 17 million improvement was related to higher activity levels and the fact that in the first half of 2002 charges for contractual litigation were recorded.

Other Activities

Operating losses amounted to euro 159 million (a euro 61 million increase over the first half of 2002) related to higher losses of Syndial Spa (euro 70 million) due essentially to the depreciation of assets for euro 41 million following the impairment test and the decline in margins only partly offset by lower fixed costs (with an aggregate effect of euro 29 million).

Corporate and financial companies

This area recorded an operating loss of euro 100 million, increasing by euro 31 million over the first half of 2002, due to higher corporate costs (euro 37 million) related to the amortization of the EST project, higher research costs and the centralization of some functions.

Net financial expense

In the first half of 2003 net financial expense (euro 40 million) decreased by euro 41 million over the first half of 2002, down 50.6%, due mainly to lower interest rates on European markets (Euribor down 0.9 percentage points) and on international markets (Libor down 0.6 percentage points) as well as higher positive exchange rate differences (euro 18 million) and the effect of exchange rates on the translation of financial charges recorded by foreign companies. These positive effects were offset in part by an increase of euro 4 billion in average net borrowings.

Net income from investments

Net income from investments in the first half of 2003 amounted to euro 80 million (euro 50 million in the first half of 2002) and represented the balance of income of euro 155 million and expense of euro 75 million. Income concerned essentially: (i) Enis share of income of subsidiaries accounted for with the equity method (euro 103 million) concerning in particular the Gas & Power, Oilfield Services and Engineering and Refining & Marketing segments; (ii) gains on disposals (euro 30 million) related essentially to the sale of Enis 20% stake in Inca International SpA in the Other activities segment (euro 29 million); (iii) dividends received by subsidiaries accounted for at cost (euro 11 million).

Expense (euro 75 million) concerned essentially Enis share in losses of subsidiaries accounted for with the equity method (euro 66 million) relating in particular to Albacom SpA (euro 39 million) and Galp Energia SGPS SA (euro 5 million related only to the writedown of euro 54 million of the difference between purchase cost and net equity).

Gains on disposals concerned the sale of business units and fixed assets made in connection with restructuring; in particular gains on disposals in the first half of 2003 amounted to euro 111 million and concerned mainly the sale of service stations and real estate in the Refining & Marketing segment.

Other extraordinary income concerned in particular the settlement paid by Edison SpA in relation with the Enimont dispute (euro 200 million).

Provisions for risks and contingencies of euro 158 million concerned in particular charges related to compliance with environmental laws and regulations in the Other

Activities (euro 63 million) and Refining & Marketing segments (euro 9 million) and costs expected to be incurred for decommissioning of inactive sites in the Other Activities segment (euro 52 million).

Redundancy incentives amounted to euro 22 million and concerned in particular the Refining & Marketing (euro 10 million) and Other Activities segments (euro 4 million).

Income taxes

Income taxes (euro 1,940 million) increased by euro 118 million over the first half of 2002, due to a euro 856 million increase in income before taxes, whose effects were offset in part by the recording of deferred tax assets related to the application of Law 448/2001 1 . The 4.3 percentage point decline in tax rate (from 40.9 to 36.6%) was due to the recording of deferred taxes mentioned above, to the fact that in the first half of 2002 the reserve for deferred taxes was increased in relation to the 10 percentage point increase in corporate taxes for oil companies in the United Kingdom (from 30 to 40%), with a euro 215 million effect, and by the 2 percentage point decline of corporate tax (Irpeg) in Italy. These effects were offset in part by the expiry of certain tax incentives (as provided for by Law 383/2001 so called DIT, Law 342/2000 on the revaluation of assets) and the impact of Law Decree 209/2002 concerning the deductibility of writedowns of investments.

Minority interests

Minority interests (euro 277 million) declined by euro 91 million over the first half of 2002, due essentially to the tender offer on Italgas shares (euro 87 million).

Net income before non-recurring items

Net income before non-recurring items amounted to euro 2,848 million, increasing by 15.2% as compared to the first half of 2002. Net income before non-recurring items is not a GAAP measure under Italian or U.S. GAAP, but Eni provides it with the intent to allow investors to better evaluate Enis trading performance also in comparison with its main competitors. The following table reports the most significant non-recurring items which influenced net income for the first half of 2003 and 2002.

(1) Law No. 448 of December 28, 2001 allows companies receiving assets in conferral to align the taxable value of conferred assets to the higher book value by paying a substitute tax amounting to 9% of the difference between the two values. Stoccaggi Gas Italia SpA, which in 2001 was conferred natural gas storage assets from Eni SpA and Snam SpA, applied this law. Therefore in Enis consolidated financial statements a temporary difference between taxable values and book values of these assets was recorded which led to the recording of a net deferred tax asset of euro 287 million (net of substitute tax for euro 154 million).

At June 30, 2003, net capital employed totaled euro 39,375 million, representing a decrease of euro 117 million over December 31, 2002, due mainly to a decrease (euro 2,697 million) in net working capital mainly related to the seasonality factors that determine revenue generation in the Gas & Power segment and higher tax liabilities. These factors were offset in part by an increase in non-current assets (euro 2,607 million). The share of the Exploration and Production, Gas & Power and Refining & Marketing segments on Enis net capital employed was 90.1% (88.3% as of December 31, 2002). The debt to equity ratio (ratio of net borrowings to net equity included minority interest) went from 0.39 at December 31, 2002 to 0.48 at June 30, 2003.

Net fixed assets (euro 35,545 million) were primarily related to the Exploration & Production (57.5%), Gas & Power (24.2%) and Refining & Marketing (8.8%) segments. Provisions for depreciation, amortization and writedowns (euro 40,106 million) represented 53% of gross fixed assets (54.1% at December 31, 2002).

Net investments in unconsolidated subsidiaries and affiliates (euro 2,719 million) consisted primarily of 33.34% of Galp Energia SGPS SA (euro 647 million), 49% of Greek natural gas secondary distribution companies EPA Thessaloniki and Thessaly

Accounts receivable financing and securities related to operations (euro 1,254 million) were made up primarily by loans made by Enis financial subsidiaries on behalf of Enis operating subsidiaries in the Exploration & Production segment (euro 257 million) and by financial companies in favour of Enis subsidiaries (euro 907 million in particular in the Gas & Power segment).

Following the conversion of financial statements expressed in currencies other than the euro at June 30, 2003 the appreciation of the euro on other currencies, in particular the US dollar (euro up 9% over December 31, 2002), determined a decline of the book value of net capital employed of euro 1,616 million, of net equity of euro 1,041 million and of net borrowings of euro 575 million.

Taxes payable and the reserve for net deferred income tax liabilities increased by euro 1,207 million due to: (i) higher liabilities for excise taxes, and other tax liabilities (euro 1,013 million) due mainly to the postponement of payment of excise taxes related to June 2003 to July 2003 in the Refining & Marketing and Gas & Power

segments (excise taxes for December were paid in December as a balance for the first 15 days and as an advance for the second half of the month); (ii) higher income taxes and reserve for net deferred income tax liabilities (euro 194 million) due mainly to deferred tax liabilities related to the determination of the fair value of fixed assets of Società Italiana per il Gas pA for the portion acquired in the tender offer (euro 374 million) and the effect of the purchase of Fortum Petroleum AS (now Eni Norge AS) (euro 145 million). These increases were offset in part by the recording of deferred tax assets net of substitute taxes due (euro 318 million) in accordance with Law No. 448/2001 by Stoccaggi Gas Italia SpA (see Income taxes above) and the effect of the translation of financial statements denominated in foreign currencies (euro 200 million).

The reserve for contingencies (euro 5,782 million) concerned essentially: the reserve for site restoration and abandonment of euro 2,103 million (euro 1,980 million at December 31, 2002), the reserve for environmental risks of euro 1,595 (euro 1,608 million at December 31, 2002), the reserve for loss adjustments and actuarial reserves of Enis insurance companies of euro 622 million (euro 593 million at December 31, 2002), the reserve for restructuring and decommissioning of production facilities of euro 348 million (euro 304 million at December 31, 2002), the reserve for contract penalties and disputes of euro 207 million (euro 211 million at December 31, 2002), the reserve for employee retirement and similar obligations of euro 138 million (euro 128 million at December 31, 2002) and the reserve for losses on subsidiaries of euro 92 million (euro 106 million at December 31, 2002).

Exploration and development

As of June 30, 2003, Enis portfolio of mineral rights consisted of 1,118 exclusive or shared interests for exploration and development in 36 countries on five continents, for a total net acreage of 256,427 square kilometers (281,682 at December 31, 2002). Of these, 42,501 square kilometers concerned production and development (41,578 at December 31, 2002). Net acreage decreased by 25,255 square kilometers, in particular outside Italy, due to releases and sale of interests in Egypt, Algeria, Yemen, Denmark/Farøe Islands, Indonesia, Australia, the United Kingdom and Nigeria, whose effects were offset in part by increases registered in Norway resulting from the purchase of Fortum Petroleum AS and in Pakistan.

In the first half of 2003, three-dimensional seismic surveys were carried out over 1,865 square kilometers (639 of which represented Enis share), while standard seismic surveys totaled 2,554 kilometers (2,074 of which represented Enis share), the former decreasing by 77% net to Eni and the latter increasing by 59% net to Eni over the first half of 2002. The decrease in the three-dimensional surveys may be attributed to the completion of survey campaigns mainly in Senegal/Guinea, Mauritania, Indonesia and Iran, while in the latter case, the increase was registered mainly in Australia.

Exploration expenditure amounted to euro 346 million (of which 91% was directed outside Italy). Outside Italy, exploration expenditure concerned mainly Egypt, the United States, Kazakhstan, Angola, Brazil, Norway 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 development and capital goods totaled euro 2,399 million, of which 91% was directed outside Italy. Development expenditure outside Italy concerned in particular fields in Libya, Iran, Angola, Nigeria and Kazakhstan. Development expenditure in Italy referred in particular to the continuation of construction of plant and infrastructure in the Val dAgri. Expenditure for the acquisition of proved and unproved property amounted to euro 7 million.

Total capital expenditure in the first half of 2003 amounted to euro 2,752 million, increasing by euro 99 million over the first half of 2002, up 3.7%.

In the first half of 2003 daily hydrocarbon production amounted to 1,527,000 boe (oil and condensates 952,000 barrels; natural gas 575,000 boe), increasing by 72,000 boe, up 4.9%, due to: (i) the purchase of the Norwegian company Fortum Petroleum; (ii) start-ups of fields mainly in Trinidad & Tobago, Australia, Iran, Nigeria, Pakistan and Algeria; (iii) production growth recorded mainly in Nigeria and Kazakhstan; (iv) the cancellation of production cuts imposed by OPEC. These increases were offset in part by: (i) the decline of mature fields; (ii) lower entitlements in Production Sharing Agreements due to higher international oil prices 2 ; (iii) the effects of production standstills in Venezuela related to a national strike in the first months of the year; (iv) the effects of the sale of assets in 2002. Production outside Italy amounted to 80.0% of Enis total production (78.3% in 2002).

Daily production of oil and condensates (952,000 barrels) increased by 33,000 barrels, up 3.6% due to increases recorded outside Italy, in particular in: (i) Norway, due to the purchase of Fortum Petroleum; (ii) Nigeria, due also to the start-up of the Abo Central field (Eni operator with a 50.19% interest); (iii) Australia, for the start-up of the Woollybutt field (Eni operator with a 65% interest); (iv) Iran, due to the start-up of the Balal (Enis interest 38.25%) and Dorood fields (Enis interest 45%); (v) Kazakhstan. These increases were offset in part by decreases recorded in Angola, following the standstill of the FPSO unit installed in the Kuito field (Enis interest 20%), the decline of mature fields in Egypt, Congo and the United Kingdom, as well as the effect of the sale of assets in 2002.

Daily production of natural gas (575,000 boe) increased by 39,000 boe, up 7.3%, due essentially to increases registered outside Italy, in particular in: (i) Norway, due to the purchase of Fortum Petroleum; (ii) Pakistan, also due to the start-up of the Bhit field (Eni operator with a 40% interest); (iii) Trinidad & Tobago for the start-up of fields in Block NMCA-1 (Enis interest 17.31%); (iv) Nigeria for the increase in natural gas volumes treated at the Bonny plant (Enis interest 10.4%); (v) Egypt. These increases were offset in part by the decline of mature fields, in particular in Italy and the United Kingdom.

Hydrocarbon production sold amounted to 267.3 million boe. The 9 million boe decrease over production was due essentially to lower withdrawals as compared to allotted shares (underlifting 3 ) outside Italy, in particular in Ecuador, Nigeria, the United Kingdom and Norway (5 million boe) and natural gas volumes consumed in operations (4.5 million boe).

Main exploration and development projects

NORTH AFRICA

In Algeria two new oil discoveries were made in Block 404 (Enis interest 25%) with the HBNE-1 and SFSW-1 wells. These wells, drilled at a depth of 3,250 meters yielded 4,000 and 3,000 barrels/day respectively in test production. The Algerian Government approved the development plan of four oil fields (El Merk Nord, El Merk Est, El Merk and El Kheit Et Tesseka) in Block 208 (Enis interest 12.25%) and one (ROME) in Block 403d (Eni is operator with a 50% interest). At the end of June the ROME field was ready for production at the expected level of about 3,000 barrels/day.

In Southern Tunisia in May, the Adam field started oil production at over 3,000 barrels/day.

WEST AFRICA

In Nigeria in April oil production started at the Abo Central level of the Abo field (Eni operator with a 50.19% interest), located in the OML 125 concession in the Nigerian offshore in a water depth ranging between 500 and 800 meters with recoverable reserves of 41 million barrels net to Eni. First oil was produced 19 months after the approval of the project which includes, when completed, 9 underwater wells (5 producing, 2 water injection and 2 gas injection wells). Oil extracted is sent to an FPSO unit with a treatment capacity of 45,000 barrels/day and a storage capacity of 800,000 barrels. Daily production is targeted at 25,000 barrels (11,000 net to Eni) in the fourth quarter of 2003, while in a later development phase it is targeted at 45,000 barrels/day (19,000 net to Eni). Abo Central is the first oil field that starts production in Nigerian deep waters and is part of the Nigerian Governments and Enis Zero Gas Flaring program: associated gas is reinjected into the field, thus allowing also to optimize oil extraction.

NORTH SEA

In the United Kingdom in July a new gas and condensate discovery was made in Block 29/5b (Enis interest 21.87%) located in the Central Graben area in the British section of the North Sea, about 240 kilometers east of Aberdeen. The discovery well drilled at a total depth of 5,750 meters, yielded one million cubic meters/day of natural gas in test production (equivalent to about 6,000 barrels/day) and 2,000 barrels/day of condensates. The well will be linked to the production facilities of the nearby Elgin/Franklin fields located in the same block.

In Denmark , in the Farøe Islands, in June 2003 the offshore 6004/17-1 Marimas well was drilled in the Marimas concession (Eni is operator with a 75% interest).

In Norway in March Eni finalized the purchase of Fortum Petroleum AS, a subsidiary of the Finnish company Fortum Oy. The purchase, with accounting effects starting on January 1, 2003, entailed a total financial requirement of dollar 975 million (of which 256 million related to the purchase of net equity and 719 related to net borrowings assumed). Assets of Fortum Petroleum (now Eni Norge AS) located in the Norwegian section of the North Sea consist of interests in the Aasgard (7%, in this field Eni already holds a 7.9% interest), Brage (12.26%) and Heidrun (5.12%) producing fields and also in Mikkel (7%, in this field Eni already holds a 7.9% interest) presently under development and Goliath (15%, operated by Eni with a 25% interest) still to be developed. In addition, Fortum Petroleum holds interests in important gas transmission infrastructures such as Haltenpipe (5%), Heidrun Gas Export (5.12%)

and Aasgard Transport (5%) linking the Aasgard and Heidrun fields to the Norwegian coast. The company also holds an interest in Franpipe (1.29%) and the related Dunkerque terminal (0.84%) in France and in Europipe II (3.66%) for transmission to the German coast. At December 31, 2002 Fortum Petroleums proved and probable reserves amounted to about 200 million boe (56% of which were oil and 44% gas); proved reserves amounted to 159 million boe. In the first half of 2003 its daily production amounted to 44,000 boe, increasing by over 40% Enis production of hydrocarbons in Norway. This transaction is part of Enis strategy of upstream growth by strengthening its presence in key area and increasing interests in already held assets in order to generate operational synergies.

At the end of June Eni purchased from an international oil company a 7.9% interest in the Tyrihans field in the North Sea.

REST OF WORLD

In Australia in April production started at the Woollybutt field (Eni is operator with a 65% interest) located in WA-234-P permit offshore the north western coast of Australia at a water depth of about 100 meters. Woollybutt production is the first to be brought on stream by Eni in Australia, where Eni has been active since the acquisition of British Borneo in 2000. Recoverable reserves amount to 13 million barrels net to Eni. Oil is produced via two subsea wells linked to an FPSO vessel. Daily production reached 40,000 barrels (26,000 net to Eni).

In Iran in January the Balal oil field started production. The field is located in the offshore of the Persian Gulf about 100 kilometers from the island of Lavan at a water depth of 70 meters. The development of the field is regulated by a buy back contract and entails the drilling of 10 wells (5 production and 5 injection wells) and the construction of three platforms. Enis capital expenditure amounted to dollar 110 million. Daily production is expected to peak at 6,000 barrels net to Eni in year 2005.

In Kazakhstan in May the partners in the project regulated by the North Caspian Sea PSA, among which Eni as single operator and except Inpex, exercised their pre-emptive rights and purchased in proportional shares the interest of British Gas that left the project. Under the Sale and Purchase Agreement the pre-emption transactions will be subject to approval of the Kazakh Government. Enis share in the project will go from 16.67% to 20.372%.The area under contract is made up of 11 blocks covering a total of over 5,500 square kilometers at a water depth of 2 to 10 meters. In this area in July 2000 the Kashagan field was discovered and subsequent appraisal allowed to define the amount of recoverable reserves of oil in the 7 to 9 billion barrels range, that could reach 13 billion barrels with gas reinjection techniques, thus making this field the most important discovery in the world in the past thirty years. The exploration campaign, expected to last six years, provides for the drilling of 6 wells and the collection of seismic data. In March 2003 the testing phase of the third and the fourth appraisal wells (KE-4 and KE-5) commenced in April and August 2002 was completed. In April 2003 drilling of the fifth appraisal well (KE-6) commenced. On June 30, 2002 the consortium and the Kazakh authorities declared Kashagan a commercial discovery and at the end of 2002 the Kashagan development plan was filed with the Kazakh authorities. At the end of June 2003 the front-end engineering was completed for the first development phase. The last three commitment exploration wells are being

drilled (Kashagan South West 1, Aktote 1 and Kairan 1) that had been started in April, May and early July 2003. In this same area in 2002 a new oil discovery was made with the Kalamkas-1 exploration well, which confirms the potential of this area. The appraisal plan for the Kalamkas structure was approved by Kazakh authorities at the end of May 2003.

In July, the second development phase of the oil, natural gas and condensate Karachaganak field was completed by the consortium made up of four international oil companies, among which Eni, as co-operator with British Gas, holds a 32.5% interest. The second phase concerned in particular: (i) the completion in the estimated time frame of a condensate treatment plant (Karachaganak Processing Centre KPC) and a compression station for the injection of part of the sour gas in the reservoir at pressures above 500 atmospheres; (ii) the laying of a 635-kilometer long pipeline with a 24 inch diameter linking the Karachaganak field to Atyrau, point of connection with the Caspian Pipeline Consortium pipeline in which Eni holds transportation rights up to 3 million tonnes/year. Production from KPC and export of the Karachaganak liquid production to the Novorossiysk terminal started on July 15. With the completion of this phase, production from the field is expected to increase from the current 220,000 boe/day to 380,000 at year end (65,000 to 110,000 boe/day net to Eni).

In Pakistan in January the Bhit gas field (Eni is operator with a 40% interest) started production. The field is located 180-kilometer north of Karachi in the Kirthar region. The development project provides for the drilling of 6 production wells, the laying of a collection network with a 24-inch diameter and 27-kilometer long, and the construction of a treatment plant working on two parallel trains for dehydration, removal of carbon dioxide and nitrogen. Gas produced is sold under a 20-year long take or pay contract to the state-owned Sui Southern Gas Company (SSGC) which will distribute it in Karachi. The plant reached a daily production of about 45,000 boe (18,000 net to Eni).

In April Eni was assigned as operator an exploration license in Block 2667-6 (Gorakh) covering an area of 2,500 square kilometers located between the provinces of Dadu and Balochistan. Plans provide for the performing of seismic surveys for two years.

In Trinidad & Tobago the Hibiscus and Chaconia natural gas fields started production. The fields are located in the NMCA-1 offshore block (Enis interest 17.31%) 50-kilometer north of Trinidad & Tobago. The development of these fields, holding recoverable reserves amounting to 70 million boe net to Eni, was performed by drilling six wells, installing a production platform and laying 120 kilometers of pipelines for carrying the gas produced to the Point Fortin liquefaction plant, from which production volumes of gas are sent to the Elba Island (Georgia) regasification plant and sold on North American markets. Eni share of capital expenditure in this project amounted to dollar 80 million. Daily production net to Eni is expected to peak at 12,000 boe in 2004.

In the United States in May the third appraisal well in the K2 field in Green Canyon Block 562-2 was completed (Enis interest 18.17%) in the Gulf of Mexico, which confirmed that recoverable reserves of the field amount to 100 million boe with an extension larger than previously estimated. Eni is operator of this development.

In Venezuela in April development started of the Corocoro field (Enis interest 26%), located at the mouth of the Orinoco river in an offshore block in the the Gulf of Paria 500-kilometer west of Caracas. The field will be developed through different phases. In the first phase, whose estimated cost is dollar 480 million (125 million net to Eni), production is targeted to 15,000 barrels of oil per day net to Eni. Subsequent phases will be determined on the basis of the results achieved in the first one.

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 ten storage concessions 4 vested by the Ministry of Productive Activities.

With decision No. 26 of February 27, 2002, the Authority for Electricity and Gas determined tariff criteria for modulation, mineral and strategic storage services for the period, starting on April 1, 2002 until March 31, 2006 and effective retroactively from June 21, 2000. On March 18, 2002 Stogit filed its proposal of tariffs for modulation, mineral and strategic storage for the first regulated period. With decision No. 49 of March 26, 2002 the Authority repealed Stogits proposal and defined tariffs for the first regulated period. Stogit filed an appeal against both Authority decisions with the Regional Administrative Court of Lombardia requesting their cancellation. The proceeding is still pending and in the meanwhile Stogit is applying the tariffs set by the Authority.

Supply and sales

In the first half of 2003, Eni supplied 34.71 billion cubic meters of natural gas for primary distribution, with a 0.27 billion cubic meter increase over the first half of 2002, up 0.8%, resulting from higher supplies from outside Italy (0.43 billion cubic meters) offset in part by lower volumes from domestic production (0.16 billion cubic meters). Increases outside Italy concerned purchases for trading (640 million cubic meters) in particular natural gas produced by Eni in the United Kingdom and imports from Norway (430 million cubic meters), while imports from Algeria, Russia and the Netherlands declined. Imports of natural gas covered 82.3% of total supplies (81.7% in the first half of 2002).

Volumes of natural gas supplies in secondary distribution outside Italy (Argentina, Hungary and Slovenia) amounted to 2.43 billion cubic meters, increasing by 25.3% over the first half of 2002 due to increased consumption, mainly in Hungary, where Eni operates through Tigaz Rt.

Sales in primary distribution

Natural gas sales in primary distribution in Italy and the rest of Europe (35.80 billion cubic meters) increased by 1.74 billion cubic meters, up 5.1% over the first half of 2002.

Natural gas sales in Italy (28.96 billion cubic meters) declined by 0.43 billion cubic meters, down 1.5%, due mainly to a decline in sales to wholesalers (1.28 billion cubic meters) and to industries (0.51 billion cubic meters) due to competitive pressures, whose effects were offset in part by higher sales to thermoelectric users (1.36 billion cubic meters) and higher consumption due to a colder winter.

Natural gas sales in the rest of Europe (6.84 billion cubic meters) increased by 2.17 billion cubic meters (up 46.5%), due to: (i) the progressive coming on line of long-term supply contracts to natural gas market operators (1.14 billion cubic meters); (ii) the start-up in the second half of 2002 of LNG supplies to the Spanish electricity company Iberdrola (0.37 billion cubic meters); (iii) the increase in natural gas trading activities in the North Sea (0.53 billion cubic meters); (iv) the start-up of sales to the Turkish market through the Blue Stream pipeline in February 2003 (0.1 billion cubic meters).

In order to meet the medium and long-term demand of natural gas in particular of the Italian market, Eni entered into long-term purchase contracts with operators in producing countries that have a residual average term of approximately 17 years. Existing contracts, which in general contain take-or-pay clauses, will ensure a total of about 67.3 billion cubic meters of natural gas per year (Russia 28.5, Algeria 21.5, Netherlands 9.8, Norway 6, LNG from Nigeria 1.5) by 2008. The average annual minimum quantity is approximately the 85% of said quantities. In the medium and long-term the development of natural gas demand in Italy and the evolution of the regulatory framework might represent a risk in the management of take-or-pay contracts. For 2003 in particular, Eni evaluates that this risk concerns about one billion cubic meters recoverable in the following three years.

As for the regulatory framework, natural gas imports for the next few years have been programmed based on the highest flexibility allowed by such contracts, assuming that access capacity to the Italian gasline network will be available in accordance with said flexibility. In fact, take-or-pay contracts entered by Eni before 1998 envisage Enis right to withdraw daily amounts larger than the average daily contractual amount; this contractual flexibility provided by the difference between the maximum daily amount Eni is entitled to and the average contractual daily amount is used in particular in winter. In case of congestion at entry points, Enis assumption may be

inconsistent with the current network code as established by the Authority for Electricity and Gas with decision No. 137/2002, also taking into account the claims filed by Eni and other operators. A negative outcome of this matter could adversely affect Enis results of operations up to a significant extent.

Sales in secondary distribution

Sales of natural gas in secondary distribution in Italy (5.04 billion cubic meters) increased by 0.28 billion cubic meters, up 5.9%, due to increased consumption and the 150,000 units increase in the number of customers served over June 30, 2002 (5.76 million as of June 30, 2003). Municipalities served were 1,205 at June 30, 2003 (1,197 at December 31, 2002).

Sales in secondary distribution outside Italy (2.43 billion cubic meters) increased by 0.49 billion cubic meters, up 25.3% due to increased consumption, mainly in Hungary.

With an outlay of euro 17 million, Eni acquired the remaining 49% interest in Fiorentina Gas Vendita SpA, a company selling natural gas and relevant services to customers. Eni now owns 100% of this company.

Development activities

Unión Fenosa Gas

After obtaining the relevant authorizations from European antitrust authorities and the Spanish Government, in July Eni finalized the purchase of a 50% interest in Unión Fenosa Gas, a subsidiary of Unión Fenosa SA with an outlay of euro 441 million. The transaction was achieved through a capital increase of Unión Fenosa Gas of euro 16 million (corresponding to 50% of its share capital after the increase) fully paid by Eni with a surcharge of euro 425 million.

Unión Fenosa Gas is active in natural gas supply and sale to final users and to power generation companies. It holds a 25-year supply contract, with an option for a 25-year extension, involving 4 billion cubic meters per year with the Egyptian Natural Gas Holding Company (EGAS) and a supply contract for about 2.5 billion cubic meters/year for Unión Fenosa SAs combined cycle power stations. It is also present in LNG through its participation to the construction of a liquefaction plant with a capacity of over 7 billion cubic meters per year near Damietta, on the Egyptian coast. In addition it is participating in the construction of a new liquefaction plant in Oman, which is expected to start operations from 2006. It also holds a 19% and a 45% interest in the Reganosa and Sagunto regasification plants, under construction.

Unión Fenosa Gas targets a 13% share of the Spanish gas market which is expected to increase by an average of about 10% per year in the next five years and to reach 42 billion cubic meters by 2010.

Hungary

After the concession of authorisations by relevant authorities, in July Tigaz (a subsidiary in which Eni holds 50% interest) finalized the purchase of a majority stake in four natural gas distribution companies (Mol-Gàz, Zsàmbèrkgàz, Gerecsegàz and Turulgàz) active in the central-northern areas of Hungary from the Hungarian national company MOL for approximately euro 68 million. These companies supply an aggregate of 150,000 customers distributing 400 million cubic meters/year of natural gas to 407 municipalities in the north eastern areas of Hungary. This transaction will strengthen Tigaz position in the natural gas distribution market.

Blue Stream

The transport system is ready for operations since December 30, 2002. Supplies to Botas started in February 2003. Botas suspended its withdrawals in March (during the first six months of operation Botas is not obliged to withdraw a minimum amount) and started again in August. Management expects that Botas will withdraw in the rest of the year the minimum volumes contracted for 2003 (approximately 800 million cubic meters, of which 400 net to Eni). Volumes transported and marketed will increase in future years and are targeted to about 16 billion cubic meters per year (8 billion net to Eni).

power generation

In the first half of 2003, sales of electricity amounted to 2,510 gigawatthour, of which approximately 37% to other Eni segments, with a decline of 95 gigawatthour over the first half of 2002, down 3.6% due to the planned maintenance standstill of the Taranto power station. Eni sold 1,652 gigawatthour of purchased electricity to eligible customers (up 862 gigawatthour), about twice as much as in the first half of 2002 due to the increase in the number of customers. Sales of steam amounted to 4,630,000 tonnes, decreasing by 363,000 tonnes, down 7.3%, due to lower production at Ravenna and Brindisi resulting from lower withdrawals from end customers.

In April in Brindisi, work started for the construction of a new combined cycle power station, with an installed capacity of about 1,170 megawatt, which will become Enis most advanced power station in operation or under construction. This power station will be made up of three power units and is targeted to produce about 10 billion kilowatthour/year as well as steam for industrial use. It will be fired with natural gas, by means of a 14-kilometer long connection to the Italian network. Capital expenditure for the construction of this power plant amounts to about euro 550 million including the connection. The completion of the first of the three units are expected by the spring of 2005.

On July 5, 2003 firing started of the first unit of the new combined cycle power station in Ferrera Erbognone. With a total capacity of 1,030 megawatts this power station is targeted to produce initially 7 billion kilowatthour/year, The Provisional Acceptance Certificate for the first 390 megawatt unit is expected in November 2003, commercial operations in spring 2004. During 2004 the other two units (390 and 250 megawatts, respectively) will be completed.

Work continued at the Ravenna power plant for the construction of two new combined cycle units with a capacity of about 780 megawatts. The first unit is expected to be completed in March 2004.

In April work started at the Mantova power station for the construction of two new cogeneration units with a capacity of about 390 megawatts each fired with natural gas. They are expected to start operations in the first half of 2005.

refining & marketing

Supply and trading

In the first half of 2003, a total of 29.81 million tonnes of oil were purchased (29.31 million in the first half of 2002), of which 16.23 million tonnes from Enis Exploration & Production segment, 7.67 million from producing countries under long-term contracts and 5.91 on the spot market. The geographic sources of oil purchased were the following: 27.3% came from West Africa, 20.8% from North Africa, 20.0% from the North Sea, 11.4% from countries of the former Soviet Union, 10.9% from the Middle East, 7.5% from Italy and 2.1% from other areas. Some 14.59 million tonnes were resold, representing an increase of 1.68 million tonnes, up 13%, over the first half of 2002. In addition, 2.24 million tonnes of intermediate products were purchased (2.34 in the first half of 2002) to be used as feedstocks in conversion plants and 7.51 million tonnes of refined products (8 in the first half of 2002) sold on markets outside Italy (5.04 million tonnes) and as a complement to own production on the Italian market (2.53 million tonnes).

Refining

Refinery intake processing in Italy and outside Italy (17.15 million tonnes) declined by 1.51 million tonnes, down 8.1%, due mainly to the finalization in 2002 of agreements concerning the Priolo refinery 5 . The overall balanced capacity utilization rate of wholly owned refineries was 97% (92% in the first half of 2002). About 36% of all oil processed came from Enis Exploration & Production division (39.1% in the first half of 2002).

Distribution of refined products

Sales of refined products (24.32 million tonnes) decreased by 1.32 million tonnes, down 5.1%; due in particular to lower sales in Italy to the petrochemical sector, oil companies and traders (overall one million tonnes), due to lower availability resulting from the agreements related to the Priolo refinery, and lower wholesale sales (0.22 million tonnes).

Retail sales in Italy and the rest of Europe (6.71 million tonnes) were stable as compared to the first half of 2002 (6.70 million tonnes).

Retail sales in Italy

Retail sales in Italy (5.38 million tonnes) decreased by 100,000 tonnes, down 1.8%, due to the sale/closure of service stations offset in part by higher sales on Enis main network also resulting from the market success of the new BluDiesel product. In the first half of 2003 retail market share decreased by 1 percentage point from 37.5 at year-end 2002 to 36.5%. Average throughput was 871,000 liters (821,000 liters in the first half of 2002, up 6.1%).

(5) In October 2002 the Priolo refinery was conferred to Erg Raffinerie Mediterranee Srl (Enis interest 28%).

Table of Contents

At June 30, 2003, Enis retail distribution network consisted of 7,500 service stations (about 50% wholly owned), a 210 unit decrease over December 31, 2002, due to the finalization of sale contracts defined in 2002 (106 service stations) and the conclusion of lease contracts (104 service stations).

In July 2003 approximately 200 IP branded service stations started selling the new Plus 98 gasoline, a high quality product in terms of performance, efficiency and cleanliness of engines. Before year end the new products is expected to be sold in an increasing number of IP branded service stations.

Retail sales outside Italy

Sales of refined products on retail markets in the rest of Europe (1.33 million tonnes) increased by 110,000 tonnes, up 9%, due to the purchase of service stations in France and central-eastern Europe finalized in the second half of 2002 and in Spain and Germany finalized in the first half of 2003 (a total of 287 units); sales on retail markets in Brazil and Africa declined by 220,000 tonnes, down 27.8% due to the sale of African assets in late 2002 and the effects of restructuring in Brazil.

At June 30, 2003, Enis retail distribution network outside Italy consisted of 3,187 service stations, with an increase of 135 units over December 31, 2002, due to purchases in Germany and Spain related to the finalization of agreements initiated in 2002 and early 2003, offset in part by the closure of service stations, mainly leased ones, in Brazil.

Within its strategy of selective development in areas with consolidated presence and interesting growth prospects, in January 2003 Eni signed an agreement for the purchase from Saras Energia SA (a company belonging to the Spanish group Saras) of its refined products distribution network in Spain consisting of 130 service stations,

Wholesale sales and other sales

Sales on wholesale markets in Italy (4.98 million tonnes) decreased by 220,000 tonnes, down 4.2%, due mainly to lower sales of fuel oil related in particular to its substitution with natural gas in the firing of power stations. Market share decreased by 1.1 percentage point from 25.6 in 2002 to 24.5%.

Sales to the petrochemical sector in Italy (1.41 million tonnes) decreased by 820,000 tonnes, down 36.8%, due mainly to lower availability of specific refinery products resulting from the agreements on the Priolo refinery, while other sales (3.37 million tonnes) decreased by 230,000 tonnes, down 6.4%, this decline concerned mainly sales to oil companies and traders.

Outside Italy, wholesale sales (3.01 million tonnes) increased by 400,000 tonnes, up 15.3%, mainly due to higher sales in Germany and Spain. Other sales (4.27 million tonnes) decreased by 240,000 tonnes, down 5.3%.

petrochemicals

Market

In the first half of 2003 the demand for petrochemical products was affected by the slowdown of world economy, whose effects were increased by the chronic overcapacity of this segment and by the competitive pressure of producers in the Middle East and South East Asia, who benefit from a lower cost structure than European producers. In this situation the recovery of margins of petrochemical products registered in the first half of 2003 was due to the fact that in the first half of 2002 margins reached their lowest historical levels and also to the sharp decline of prices in euro of oil-based feedstocks, as compared to a slower decline of prices of products in the second quarter of 2003. Forecasts for the rest of the year indicate a slight recovery of demand while margins are under the threat of price increases in oil-based feedstocks.

The prices of Enis principal products increased on average by 15%; the main increases concerned intermediates (up 31%), aromatics (up 28.4%, especially benzene), olefins (up 22.2%, in particular butadiene and propylene), styrenes (up 11.3%, in particular styrene) and polyethylenes (up 9.3%, in particular LDPE and LLDPE).

Sales production

Sales of petrochemical products (2,625,000 tonnes) decreased by 239,000 tonnes, down 8.3%, due to a generally weak demand, in particular in the second quarter of 2003. Production (3,589,000 tonnes) decreased by 47,000 tonnes, down 1.3%.

The average capacity utilization rate calculated on nominal capacity decreased by 2.3 percentage points (from 77 to 74.7%), this decline concerned in particular basic petrochemicals and elastomers, while the utilization rate of styrene plants increased.

About 37.5% of total production was directed to Enis own production cycle (36.4% in the first half of 2002). Oil-based feedstocks supplied by Enis Refining & Marketing segment covered about 38% of requirements in the first half of 2003 (53% in the first half of 2002).

Basic petrochemicals

Sales of basic petrochemicals (1,394,000 tonnes) decreased by 89,000 tonnes, down 6%, due to lower olefin sales related to a decline in demand for downstream products and lower product availability at Dunkerque (in particular ethylene down 20% and propylene down 8%), due to plant standstills related to problems with workers unions, and aromatics (in particular benzene down 13%).

Basic petrochemical production (2,120,000 tonnes) decreased by 83,000 tonnes, down 3.8%, mainly in olefins (down 4.3%) and intermediates (down 9.3%), the latter due to the planned standstill of the phenol plant in Mantova.

Table of Contents

Styrene and elastomers

Styrene and elastomer sales (581,000 tonnes) declined by 20,000 tonnes, down 3.3%, due in particular to declines in styrenes related to weak demand (ABS-SAN down 9% and compact polystyrene down 5%); elastomer sales were stable due to a favourable trend in BR and SBR rubbers and latices (which increased between 2 and 4%), whose effects were offset by the decline in sales of thermoplastic rubber (down 5%).

Production (814,000 tonnes) increased by 32,000 tonnes, up 4.1%. This increase concerned in particular styrene. In elastomers the slight increases in production of latices and SBR rubbers were offset by the decline in production of thermoplastic rubbers in line with decreasing demand.

Procedure for the sale of elastomers

The procedure for the sale of the elastomer business reached the final phase of interest for five production plants; Ravenna and Champagnier are not included in this procedure. Negotiations will proceed separately for the following plants and production sites: (i) Baytown (Houston, Texas); (ii) Hythe (United Kingdom); (iii) Grangemouth (United Kingdom); (iv) ethylene-propylene rubber plant in Ferrara; (v) nitrylic rubber plant in Porto Torres. None of the mentioned plants is integrated with the Ravenna plant, which is going to be restructured through a plan of efficiency improvement and production line selection aiming at restoring profitability, given operating losses of the past few years which at present show a structural character. This plan will imply a deep organizational and productive reorganization.

oilfield services and engineering

Marketing performance

In the first half of 2003, oilfield services activities benefited from the positive trend of the demand for services from oil companies which concerned all of its business areas. Profitability in the key Offshore construction area was however affected by the increasing share of EPIC (Engineering, Procurement, Installation, Commissioning) contracts which do not foresee the use of vessels in their initial phases. In engineering the demand for plant and equipment was weak due to uncertainties in the prospect of future recovery of world economy, which led many important companies to review their capital expenditure decisions.

In the first half of 2003 orders acquired (euro 3,319 million) increased by euro 148 million, up 11% as compared to the first half of 2002. Of these 92% related to work to be carried out outside Italy, while 13% represented work originated by Eni companies. Enis order backlog (euro 10,619 million at June 30, 2003) increased by euro 554 million over December 31, 2002, up 5.5%. Orders from Eni companies amounted to 14% of the total, while projects to be carried out outside Italy amounted to 81%.

Project high speed/high capacity train tracks from Milan to Bologna.

Within the project for the construction of the tracks for high speed/high capacity trains from Milan to Bologna an addendum to the contract is in the negotiation phase between Cepav Uno (in which Eni holds a 50.36% interest) and TAV SpA. The addendum intends to redefine the terms and conditions of the contract following the delays in the contracts execution due to the need to coordinate construction works and existing infrastructure. This led to a new plan for the continuation of works and to technical changes requested by the parties (namely local administrations) involved in the project. The renewed project was divided into five functional stages that are expected to be completed between the spring of 2006 and late 2008. The consortium has been awarded a lump sum payment related to the new terms and conditions and a further payment related to the 26 changes and alterations agreed.

research and development

Main results

In the first half of 2003, Eni invested euro 81 million in research and development (euro 86 million in the first half of 2002). Technologies transferred to the industrial level were numerous, while others are in an advanced development phase.

In the Exploration & Production segment, the main research areas were:

| | Expandable screen technology, which allows to control sand
production in a well. In the first half of 2003 three wells in
open hole were completed and yielded interesting results. Other
three open hole installations are expected to be completed before
year end in Italy (for natural gas storage) and Nigeria (oil); |
| --- | --- |
| | Prevention of corrosion by means of fiber reinforced plastic
pipes, employed in the Ragusa field instead of steel pipes, which
were employed in the past and showed corrosion risk due to the
presence of
CO2. Savings obtained from this application
in terms of accident prevention and production loss correspond to
approximately 1% of the fields annual production. This is the first
installation for the transport of crude oil of this kind in Italy; |
| | a
proprietary zeolite was identified with significant capacity of
absorbing nitrogen and carbon dioxide from natural gas. |

Some technologies entered the development phase:

| | Field monitoring and reservoir management through Time-lapse
activities, Time-lapse seismic (a 3D seismic repeated over time
also called 4D seismic) proved to be an efficient tool for
reservoir monitoring and management and positively influences
business. The industrialization of the Eni Time-lapse project was
consolidated after a long research phase and application testing
all over the world. At present this method is used in some fields
in the United Kingdom and the USA; |
| --- | --- |
| | Improvement of the petrophysical characterization of reservoirs
by means of neural networks, NN codes were developed by central
research and inserted in a commercial code (GeoFrame) which is
routinely used and provides a high quality interpretation of the
reservoirs petrophysics. |

Among the technologies under development worth mentioning are: flow assurance techniques (such as pipe in pipe) for deep water operations and for floating production systems. Various actions were performed in order to define and optimize non-damaging drilling and completion fluids and to identify formulas for advanced wells fluids.

In the Gas & Power segment the objective of safety and efficiency of the transmission network led to cooperation with Italian universities and with international organizations such as the European group for research on natural gas (GERG). Underway are research projects on non destructive systems for the identification of corrosion, methods for analyzing safety and reliability of gas transmission networks, with specific reference to unstable areas. Further research work concerned the setup of a floating LNG plant integrated for the production, storage, transmission and regasification of natural gas and the improvement of pipe soldering and laying techniques.

In the Refining & Marketing segment, work continued for the manufacture of refined products (gasoline, diesel fuel and lubricants) with high quality and low environmental impact. With reference to the issue of conversion of gas to liquids (GTL) cooperation continues with the Institut Français du Pétrole (IFP) for the development of a wax technology via Fischer-Tropsch and the related wax upgrading via hydrocracker.

In the Petrochemical segment, research concerned the improvement of processes, with particular attention to catalytic systems in order to produce polymers (polyethylene, styrene, elastomers) with better characteristics and lower costs, in particular by maximising the use of low cost feedstocks giving rise to few by-products. Relevant intersegment projects continued such as:

| | EST (Eni Slurry Technology) aimed at allowing the treatment and
upgrading of heavy crudes while eliminating the formation of fuel oil,
a polluting and little valued by-product. A demonstration unit is
being built in Taranto in order to bring this technology to industrial
application; |

| | innovative technologies for the manufacture of gasoil
with less than 10 ppm of sulphur, also aimed at a significant
reduction of particulate in exhaust gases; |
| | innovative technologies
for the production of hydrogen for powering vehicles and for
stationary use, including a new process for the production of hydrogen
with CO 2 confinement; |
| | advanced technologies for the transmission of gas in pipe, with the
construction of test pipelines in high grade steel for the high
capacity transmission of gas on long distances at high pressure; |
| | technologies for the confinement and management of sulphur in oil and

Subsequent events

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

Managements expectations of operations

Trends in 2003 of main outside variables that influence Enis results of operations are indicated below:

| | worldwide demand for oil is expected to increase slightly over 2002 (up
1.4%) due
to the recovery of economy in the USA and Asia in the second half of 2003.
Enis
forecast on oil prices in 2003 indicates an average price of Brent of
about 28
dollars/barrel (up 12% over 2002) that reflects an hypothesis of prices in
the range
of 26-28 dollars/barrels in the rest of the year resulting from increased
consumption,
low stocks and continuing geopolitical tension; |
| --- | --- |
| | in 2003 the euro is expected to remain quite strong as compared to the
dollar, due
to the adjustment process of imbalances in US economy whose effects are
offset
in part by the different growth rates in the USA and Europe. Eni forecasts
an average
euro/dollar exchange rate of about 1.11 dollars per euro, a 17% increase
as compared
to the average exchange rate of 2002 (1 euro = 0.946 US dollar); |
| | demand for natural gas in Italy is expected to increase by over 7% compared
to
2002, due to increased consumption from residential and commercial users,
due
mainly to the effect of weather conditions and for the production of
electricity;
assuming normal temperatures this increase would be reduced to about 3.5%; |

refining margins in Europe are expected to recover compared to the depressed levels of 2002. The trend of margins will tend to a progressive decline in the course of 2003 due to a weak demand for refined products, the risk of further increases in the prices of oil-based feedstocks and lessening of contingent pressures (international tension, a cold winter in the northern hemisphere) that had kept margins up in the first part of the year.

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

| | daily production of hydrocarbons, net of the effect of the rationalization
of the
portfolio of mineral assets, is forecasted to grow as compared to 2002 in
line
with the planned average growth rate for the 2002-2006 period
(approximately 6%); |
| --- | --- |
| | 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
slightly
as compared to 2002, expected values take into account in particular a
decline in
sales to wholesalers and industries, offset by an increase in sales for
thermoelectric
production. Volumes sold, including secondary distribution in Europe, are
expected
to increase by 31%; |
| | electricity production sold is expected to increase by over 8% as compared
to 2002; |
| | total refinery processing intake on wholly owned refineries is expected to
decline
by about 2% due to the progressive coming on line of agreements on the
sale of
the Priolo refinery (a decline of 7.5 million tonnes by 2006). The overall
balanced
capacity utilization rate of wholly owned refineries is expected to
increase over
2002 (99%); |
| | sales of refined products on retail markets in Italy and the rest of Europe
are
expected to increase. Higher volumes sold in the rest of Europe due to the
finalization
of the purchase of service stations in Spain, France and Germany defined
in 2002
and on Enis main network in Italy will be able to offset a decline in
Italy due to
the effects of the rationalization process. Average throughput is expected
to increase,
also due to higher sales on Enis main network. |

In 2003 capital expenditure is expected to amount to approximately euro 8.5 billion; about 95% of these investments will be made in the Exploration & Production, Gas & Power and Refining & Marketing segments.

Accounting and reporting policies

The unaudited interim condensed consolidated financial statements of Eni included herein have been prepared in accordance with the criteria determined by Consob, the Italian Stock Exchange Commission, in its regulation included in decision No. 11971 of May 14, 1999 and subsequent amendments.

Enis 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, 2002 and June 30, 2002 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, 2002, while comparisons of balance sheet items reflect amounts as reported at December 31, 2002. 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 2003 concern the 100% purchase of the Norwegian oil company Fortum Petroleum AS (now Eni Norge AS).

The accounting and reporting policies applied to the unaudited interim condensed consolidated financial statements for the six months ended June 30, 2003 are consistent with those applied for the preparation of the consolidated financial statements for the year ended December 31, 2002, to which reference should be made.

The consolidated report on the first half of 2003 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.

	3,175	440	(653	)	(35	)	1,138	4,065	3,182

Intangible assets of euro 4,065 million concern primarily: (i) the difference between the purchase price of consolidated investments and the fair value of corresponding net equity (euro 2,163 million), related in particular to the Public Offering on Società Italiana per il Gas pA shares (euro 1,146 million), the purchase of the Bouygues Offshore SA (now Saipem SA) (euro 779 million) and the purchase of the Lasmo Plc (now Eni Lasmo Plc) (euro 226 million); (ii) concessions, licenses, trademarks and similar rights (euro 989 million), related in particular to the acquisition of natural gas transportation rights from Algeria (euro 731 million) and concessions for mineral exploration (euro 112 million); (iii) exploration permits (euro 214 million). The determination of the difference between the purchase price and the fair value of corresponding net equity related to the Public Offering on Società Italiana per il Gas pA shares, as the attribution of the fair values to the other activities and liabilities, is a provisional estimate in considering the technical time needed for a correct attribution of the fair value.

Investments for euro 440 million related primarily to costs for exploration activities (euro 346 million) which in the first half of 2003 was amortized in full in the period incurred (euro 442 million in the first half of 2002, of which euro 428 million was related to exploration activities amortized in full in the period incurred).

Amortization amounted to euro 653 million and related essentially to exploration costs for euro 438 million (euro 492 million in the first half of 2002).

Other changes of euro 1,138 million relate primarily to the attribution of the difference between the purchase price of consolidated investments and the fair value of corresponding net equity related to the Public Offering on Società Italiana per il Gas pA shares (euro 1,117 million).

Capital expenditures of euro 3,530 million (euro 2,932 million in the corresponding period of 2002) relate primarily to the Exploration & Production segment (euro 2,399 million), Gas & Power segment (euro 630 million), Refining & Marketing segment (euro 272 million) and Oilfield Services and Engineering segment (euro 136

million, of which euro 128 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 1,062 million were primarily due to the purchase of Fortum Petroleum AS (now Eni Norge AS) (euro 1,077 million).

Other changes of euro 554 million relate primarily to the adjustment at the fair value of the fixed assets due to the Public Offering on Società Italiana per il Gas pA shares (euro 978 million), such increase was partially offset by writedowns of euro 259 million in particular related to the Exploration & Production segment (euro 129 million), the Petrochemical segment (euro 83 million) and Syndial SpA (euro 41 million) and the sale of assets (euro 104 million) primarily made by the Exploration & Production segment (euro 78 million).

Monetary revaluations included in the gross and net value of fixed assets amount to euro 1,168 and 59 million respectively (euro 1,179 and 64 million at December 31, 2002).

At June 30, 2003 fixed assets have been pledged for euro 488 million primarily as collateral on debt incurred by Eni (euro 489 million at December 31, 2002).

Securities	311	294	2
Treasury shares	2,838	3,098
	7,333	7,343	1,300

Investments for euro 2,693 million decreased by euro 86 million. Such decrease was due primarily to writedowns of investments (euro 66 million, of which euro 39 million related to Albacom SpA), to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 55 million) and to sales and capital stock repayments (euro 50 million, of which euro 25 million related to the capital stock repayment of Conserv Inc (in liquidation)). Such decrease has been partially offset by new acquisitions and capital stock increase subscriptions (euro 78 million, of which euro 37 million related to capital stock increase subscription of United Gas Derivatives Co (UGDC) and euro 20 million related to a conferred business for euro 14 million and a capital stock increase subscription for euro 6 million to Marghera Servizi Industriali Srl).

Receivables for euro 1,258 million concern loans made for operating purpose for euro 1,232 million (euro 1,387 at December 31, 2002) and investments for euro 26 million (euro 18 million at December 31, 2002). The decrease for loans made for operating purpose for euro 155 million was due primarily to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 103 million). Receivables are granted

primarily by the Gas & Power segment (euro 907 million) and the Exploration & Production segment (euro 257 million). Receivables due within twelve months amount to euro 174 million (euro 119 million at December 31, 2002), those due beyond twelve months amount to euro 1,084 million, of these euro 386 million are due beyond five years (euro 1,286 and 441 million at December 31, 2002, respectively).

Securities for euro 294 million decreased by euro 17 million. This decrease was due primarily to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 18 million). Securities for euro 22 million are related to operations (euro 21 million at December 31, 2002).

Treasury shares amount to euro 3,098 million (euro 2,838 million at December 31, 2002) and consist of 225,303,687 ordinary shares nominal value 1 euro owned by Eni SpA (206,637,561 ordinary shares nominal value 1 euro, at December 31, 2002). Such shares are stated at cost and have been repurchased to increase shareholders value in accordance with the decisions of Eni shareholders meeting.

Crude oil and petroleum products inventories for euro 645 million (euro 595 million at December 31, 2002) represent certain minimum quantities (compulsory stock) required by law and natural gas inventories for euro 39 million (the same amount at December 31, 2002) represent strategic stock; natural gas inventories valued at euro 385 million, are used to satisfy peak demand (euro 571 million at December 31, 2002).

Receivables are net of the allowance for doubtful accounts of euro 783 million (euro 848 million at December 31, 2002).

The decrease in trade receivables for euro 921 million relates in particular to the Gas & Power segment (euro 694 million), and it is due primarily to the seasonality in demand for natural gas and to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 99 million).

Financing receivables of euro 1,081 million include loans made for operating purposes for euro 1,029 million (euro 1,237 million at December 31, 2002), amounts due to Enis financing subsidiaries from banks and other financing institutions for euro 44 million (euro 1,454 million at December 31, 2002) and amounts due to Enis non-financing subsidiaries from banks for euro 8 million (euro 11 million at December 31, 2002). The amounts due to Enis financing subsidiaries from banks and other financing institutions decreased by euro 1,410 million. Such decrease was due primarily to the utilization of the deposit in escrow, constituted by Enifin SpA in 2002 and related to the Public Offering on Società Italiana per il Gas pA shares (euro 1,447 million).

Financing receivables with an expiry date within 90 days are euro 44 million (euro 1,463 million at December 31, 2002).

Other receivables for euro 3,843 million include primarily accounts receivable from Italian tax authorities for euro 1,233 million (euro 1,786 million at December 31, 2002), accounts receivable from joint venture partners related to exploration and production activities for euro 751 million (euro 758 million at December 31, 2002) and foreign tax authorities for euro 327 million (euro 314 million at December 31, 2002). The decrease in income tax credits due to Italian tax authorities of euro 553 million depends primarily on the release of receivables related to taxes due for the period (euro 337 million) and the decrease of receivables for value added tax (VAT) (euro 223 million) in relation to the recovery of the advance paid on December 2002 in accordance with art. 6 of Law No. 405/1990.

(*) Each individual amount included herein does not exceed euro 50 million.

The Income tax liabilities reserve for euro 3,505 million includes net deferred tax liabilities, current taxes accrued in the six month period, as well as expected liabilities for the settlement of tax proceeding. The euro 894 million increase is primarily due to the net provisions of the period (euro 702 million), to the deferred tax liabilities of the attribution of fair value to the fixed assets of Società Italiana per il Gas pA following the Public Offering (euro 374 million), to the purchase of Fortum Petroleum AS (now Eni Norge AS) (euro 145 million) and the set-off, for each company, of tax assets and deferred tax liabilities (euro 75 million). Such increase has been partially offset by net exchange differences due to the translation of financial statements prepared in foreign currencies (euro 357 million).

The Site restoration and abandonment reserve of euro 2,103 represents primarily the estimated costs for well-plugging, abandonment and site restoration (euro 1,923 million).

The Environmental risks reserve of euro 1,595 represents primarily the expected liabilities for remediation for Syndial SpA (euro 1,314 million) and the Refining & Marketing segment (euro 160 million).

The Loss adjustments and actuarial reserves for Enis insurance companies reserve of euro 622 million represents the expected liabilities following the losses insured by Padana Assicurazioni SpA.

Financial debt amounted to euro 15,610 million and decreased by euro 96 million primarily due to exchange rate differences due to the translation of financial statements prepared in foreign currencies (euro 618 million) and the balance of payments and new proceeds of liabilities (euro 186 million). Such decrease was partially offset by the change in the scope of consolidation (euro 698 million, of which euro 685 million relates to the purchase of Fortum Petroleum AS (now Eni Norge AS)). The balance of payments and new proceeds of liabilities of euro 186 million includes new bonds issued within the Medium Term Notes Program due beyond 12 months for euro 1,926 million, of which euro 1,500 million issued by Eni SpA.

Financial debt at June 30, 2003 was as follows:

	634	8,252	8,886
	7,358	8,252	15,610

Debt to tax authorities of euro 2,548 million increased by euro 724 million due to the increase in excise tax and custom duties and other tax liabilities (euro 1,013 million), following primarily the payment made by the Refining & Marketing segment and Gas & Power segment on July 2003 of excise tax and custom duties due for June 2003 (excise tax and custom duties due for the December are paid in the same month of December in full for the first half of the month and in advance for the second half of the month). This increase was partially offset by the decrease in income taxes (euro 289 million).

Other debts of euro 3,473 million (euro 3,426 million at December 31, 2002) are related in particular to debt to joint venture partners for the exploration and production activities for euro 921 million (euro 810 million at December 31, 2002), and to investment activities for euro 867 million, of which euro 44 million relates to debt to joint venture partners for the exploration and production activities (euro 960 and 170 million respectively at December 31, 2002).

Certain debt, in the amount of euro 487 million (euro 409 million at December 31, 2002) is guaranteed by mortgages and liens on the fixed assets of consolidated companies and by pledges on marketable securities.

Commitments concerning derivative contracts for euro 11,737 million (euro 11,917 million at December 31, 2002) concern activities aimed at reducing market risk from changes in interest rates, foreign exchange rates and commodity prices. Enis 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 Enis finance companies and criteria of eligible counterparties in derivative transactions.

ENI REPORT ON THE FIRST HALF OF 2003 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS PAGEBREAK

Table of Contents

As far as interest rate and foreign exchange rate risks are concerned, the calculation and measurement techniques followed by Enis 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 SpAs Treasury Department is responsible for monitoring compliance with Enis 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 speculative basis.

Obligations for purchase and sale of fixed assets of euro 803 million (euro 3,774 million at December 31, 2002) concern investments for euro 617 million (euro 3,596 million at December 31, 2002) and securities for euro 186 million (euro 178 million at December 31, 2002). Obligations relating to investments concern primarily: (i) commitments to Unión Fenosa SA for the acquisition of 50% of Unión Fenosa Gas SA through a capital contribution of euro 441 million; (ii) obligation related to a call option for the purchase by Erg SpA of a 28% share of Erg Raffinerie Mediterranee Srl (euro 102 million). The decrease for euro 2,979 million concerns primarily the execution of the Public Offering on Società Italiana per il Gas pA shares (euro 2,550 million) and the purchase of 100% of the Norwegian company Fortum Petroleum AS (now Eni Norge AS) (euro 400 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 renown by the shareholders.

Commitments of euro 462 million (euro 441 million at December 31, 2002) are primarily related to: (i) agreements between EniChem SpA and various government entities, employee and trade groups whereby EniChem SpA (now Syndial SpA) has committed to invest approximately euro 247 million (euro 223 million at December 31, 2002) 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 with the Basilicata Region. Whereby Eni has agreed to invest, also on account of Enterprise SpA, euro 200 million in the future in connection with Enis development plan of oil fields in Val dAgri (euro 206 million at December 31, 2002).

Risks of euro 942 million (euro 1,015 million at December 31, 2002) are primarily associated with: (i) contractual assurances given to acquirors of certain investments and businesses of Eni for euro 418 million (euro 393 million at December 31, 2002); (ii) potential risks associated with the value of assets of third parties under the custody of Eni for euro 337 million (euro 431 million at December 31, 2002). The decrease for euro 94 million concerns primarily the reduction of natural gas inventories of Stoccaggi Gas Italia SpA (euro 77 million); (iii) environmental proceedings for euro 136 million (euro 137 million at December 31, 2002); (iv) tax proceedings for euro 48 million (euro 44 million at December 31, 2002).

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 an adverse effect on Enis consolidated financial statements.

The following is a summary of significant legal matters in which Eni is involved. Unless otherwise indicated, no provisions have been made for the following proceedings as Eni believes that losses are not probable.

Judicial or arbitration proceedings

EniChem SpA (now Syndial SpA) Serfactoring SpA

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), that has been merged in EniChem SpA). Such receivables were transferred by Agricoltura and Terni Industrie Chimiche 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 Industrie Chimiche 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. Judgement on these proceedings, which have all been joined, is currently still pending.

Eni SpA Syndial SpA

In 1992, Eni SpA and EniChem SpA initiated an arbitration proceeding against Montedison SpA and its subsidiaries in relation to guarantee given by them in connection with the formation of Enimont SpA. On March 6, 2003 Eni and EniChem accepted the settlement proposal presented by Edison SpA for the closing of the arbitration proceeding. With this settlement Edison accepted to pay EniChem euro 200 million to be paid in four installments of euro 50 million each, the first one paid on March 6, 2003 and the remaining to be paid each following year with interests accrued; this delayed payment is supported by bank guarantees payable on first request. This settlement concerns expense paid or accrued by EniChem in previous years. It does not include EniChems claim to be indemnified by Edison for any expense related to damage made to third parties by the operation of plants and facilities before Montedisons conferral, even if occurred later. These are environmental damages claimed by the State and related the Mantova site and any damage that could be claimed by the State and/or other parties as alleged consequence of specific environmental damage solutions in the Brindisi and Priolo sites. The settlement of any dispute is entrusted to ordinary courts.

Syndial SpA

In 2002 EniChem was summoned by ICR Intermedi Chimici di Ravenna Srl before the Court of Milan in relation to a breach of a preliminary agreement for the purchase of an industrial area in Ravenna. ICR requested a payment of compensatory damage approximately for euro 46 million, of which euro 3 million of accruing damage and euro 43 million of loss of profit.

Tax proceedings

Eni SpA

Agip SpA (merged in Eni SpA in 1997) 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, and became definitive for the acquiescence of the tax authorities. 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 uses of loss carryforwards for euro 20 million. The provincial Tax Commission of Milan Accepted Enis claim with decision issued on May 3, 2001. On June 26, 2002 Tax authorities appealed to the Regional Tax Commission. Eni recorded a provision to risk reserve for this legal proceeding.

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 (merged in Eni SpA in 2002) 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 believes that natural gas used for electricity generation is not subject to this additional excise tax. 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

Eni SpA

In relation to some investigations about an alleged subsidence phenomenon caused by hydrocarbon exploration, on February 5, 2003, following the decision of the Court of Rovigo, the Nucleo Operativo Ecologico of Carabinieri of Venice placed under preliminary seizure the Naomi/Pandora platform, the Naomi 4 Dir, Naomi 2 Dir and 3 Dir Pandora 2 Dir wells, and the underwater pipeline for the transportation of the production to Casalborsetti. Eni, taking account of the observations on which the public prosecutor of the Court of Rovigo based its case, constituted an independent interdisciplinary scientific commission, composed of the most important experts of subsidence caused by hydrocarbon exploration, with the aim of verifying the size and effects and any appropriate action to reduce or to neutralize any subsidence phenomenon in the Ravenna and North Adriatic area. Eni, based on the first conclusions of this commission, believes that the hydrocarbon exploration of Naomi/Pandora field is not responsible for any coastal subsidence phenomenon.

In 1997 Grifil SpA summoned AgipPetroli SpA (merged in Eni SpA in 2002) before the Court of La Spezia. Grifil requested the payment for the reclaiming of a polluted soil in La Spezias refinery (which was closed in 1985), and acquired by Italiana Petroli SpA in 1996, later merged in AgipPetroli SpA. The claims for these damages amount to euro 103 million. At the end of 2002 Grifil and AgipPetroli reached an agreement through which Eni had to pay half of the reclaiming costs, which were set by an independent appraisal to euro 19 million and, however, up

to a maximum of euro 9.5 million, and Grifil had the obligation to reclaim the soil and to renounce to any claims. Grifil did not execute the settled obligations, however, maintaining the possibility of precautionary requests and actions for recourse, Eni decided to reclaim the polluted soil with the combined aid (for the 13% of the costs) of a company interested in developing the land parcel. Reclaiming will start after obtaining the necessary authorizations. The proceeding started by Grifil before the Court of La Spezia is still pending. Another proceeding against some managers of AgipPetroli is in the inquiry phase. Such proceeding concern an alleged violation of article 51 bis of Legislative Decree No. 22/1997 (omitted reclaim) for the 2000-2002 three-year period.

In 1999, the public prosecutor of Gela started an investigation against a former manager of the refinery in order to ascertain an alleged soil and sea pollution caused by the discharge of effluents by the refinery. On November 2002, Italia Nostra and the association Amici della Terra filed civil claims within this proceeding and requested the payment of compensatory damage from AgipPetroli SpA (now merged into Eni SpA) for a total of euro 15,050 million. On July 2003 the relevant Court decided for the transmission of the inquiries to the public prosecutor, recognizing a violation of article 440 of penal code (water and food substances corruption).

In 2000, the public prosecutor of Gela started an investigation on alleged prohibited emissions from AgipPetroli SpAs refinery, which are purported to have had negative effects on the health of a number of citizens of Gela, and on AgipPetrolis lack of declaration of such emission 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. The Municipality of Gela, the Province of Caltanissetta and others filed civil claims in this proceeding and requested the payment of compensatory damage from AgipPetroli for a total of euro 878 million. The judgment of first instance before the Court of Gela is still pending.

On March 2002 the public prosecutor of Siracusa started an investigation against two former managers of Priolos refinery for intentional corruption of water for human consumption and disposed a technical opinion, not concluded yet, to ascertain an alleged possibility of infiltrations of refinery oil products into the deep water-bearing stratum used for human consumption in the Priolo area. The proceeding is still in the preliminary investigation phase. In consideration of the complexity of the investigation a qualified company has been given the task to verify the cause, the origin and the extension of the infiltration. Only after the conclusion of the inquiry phase Eni will forecast the eventual consequences of these investigations.

On March 2002, in connection with a fire in the refinery of Gela, the public prosecutor of Gela started an investigation against the manager of the refinery and others. At the end of investigation the public prosecutor asked the judge for preliminary investigation to schedule the preliminary hearing. On July 2003 the judge arranged an hearing for November 5, 2003. The accusation concerns culpable fire, environmental crimes and crimes against the beauties of nature.

Syndial SpA

In 1992, the Ministry 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, an action started 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 Eni 1 , 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. With reference to the 25 years period examined in the proceeding (1971-1995) EniChem managed the CVM-PVC plant from 1987 to 1993, while land parcels and other plants were managed by EniChem only from 1990 onwards. The inclusion of Eni SpA as defendant for environmental damage and crimes related to injuries and death of persons that had worked near the Porto Marghera petrochemical plant is based on the fact that Eni SpA is a shareholder of companies operating in Porto Marghera, rather than on Enis participation in managing such companies. Three more person that for a short period of time (some months for two of them and about two years for the third one) were employed in Eni SpA or other companies directly involved in the managing of the plant. In the hearings at the end of June 2001 public prosecution (Italian Government, Veneto Region, Venice Province and three municipalities) and private prosecution (69 persons and entities) requested a payment for damages against all the 28 defendants and their companies (Montedison SpA, Montefibre SpA, EniChem SpA and Eni SpA). Plaintiffs did not specify which damages were effectively caused by the alleged crime; they submitted to the Court the decision about the division of the damages between the defendants. Damage payments were requested for an amount of euro 511 million more compensatory liquidation of environmental damage, and, provisionally, for a total amount of euro 2,035 million in case the judge should not identify evidence for each specific case. The State Attorney estimated the cost of environmental remediation in euro 36,952 million and the illicit profit of defendants of euro 5,970 million. Damage payment has been requested jointly of all defendants. Only for the environmental damage did the State Attorney request individual payment of each defendant found guilty. Another defendant accepted to correspond a payment of about euro 260 million. On November 2, 2001 the Court of Venice acquitted all defendants. The appeal against the decision was presented by the public prosecutor, the State Attorney of the Ministry of Environment and the Council of Ministers, 5 public entities, 12 associations and other entities and 48 persons. Damage payments are the same requested in the first instance with the exception of the State Attorney which accepted the payment agreed with one of the defendant and, consequently, requested the payment for environmental damage only to EniChem. The damage payments requested are: (i) public entities: euro 98 million; (ii) persons: euro 14 million; (iii) associations and other entities: euro 4 million (Legambiente Nazionale requested the payment in civil judgment). Total damage payment, requested jointly of all defendants with the exclusion of the requests of the State Attorney, amounts to euro 116 million. There are some possible different criteria for the division of the damages between the two defendants: (i) half and half; (ii) in relation to the management of the plant (in the period from 1973 to 2001, CVM plant was managed by Montedison for 14 years and EniChem for 6 years; the other plants were managed by Montedison for 17 years and by EniChem for 10 years); (iii) in relation to the years of sentence requested by the public prosecutor to each defendant. The State Attorney confirmed the requests of the first instance only against EniChem and Eni. Total damage payment amount to euro 46,997 million or euro 42,928 million depending to the division criteria which would be choice for the environmental damage. Eni settled a provision to risk reserve for this legal proceeding.

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 who managed these plants from 1983 to 1993. At the end of preliminary investigation the public prosecutor asked the dismissal for the employees and the managers of EniChem. The judge for preliminary investigation has not yet given his opinion.

On December 18, 2002 EniChem, jointly with Ambiente SpA and European Vinyls Corporation Italia SpA, was summoned before the Court of Venice by the province of Venice. The province requested an environmental damage, not quantified, caused to the lagoon of Venice by Porto Margheras plants, which were already object of two previous proceedings. EniChem appeared before the court and presented several exceptions and demanded the nullity of the action for the indeterminateness of the requests. The judge accepted the request of nullity and disposed the renewal of the action. Subordinately to the ascertainment of the illegitimacy of the requests, EVC Italia presented an action for recourse against EniChem and Ambiente.

On January 16, 2003 the Court of Siracusa ordered the imprisonment of 7 employees of EniChem SpA and Polimeri Europa SpA and house arrest for another 10 employees of the same companies. Those persons are accused of an

illicit mismanagement relating to the production, disposal and treatment of liquid and solid waste materials and obtaining an illicit income. On February 6, 2003 the Court of Reviews decided the transformation of the imprisonments in house arrest and cancelled the detention for other employees inquired. Polimeri Europa and EniChem, as injured party, named their defense attorney.

On April 14, 2003 the President of the Regional Council of Calabria, as Delegated Commissioner for Environmental Emergency in the Calabria Region, started an action against EniChem SpA related to environmental damages for euro 129 million and to financial and non-financial damages for euro 250 million (plus interest and compensation) caused by Pertusola Sud SpA (now merged in EniChem) in the area of Crotone. On June 6, 2003 Syndial SpA appeared before the court and requested the rejection of the damages and, as counterclaim, the payment of the total costs of reclaiming action already started.

On May 2003 the Minister of Environment summoned Syndial SpA and 11 of its employees and managers before the Court of Turin and requested an environmental damage for euro 2,396 million in relation to DDT pollution in the Maggiore lake caused by Pieve Vergontes plant.

Snam Rete Gas SpA

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 tax was payable from April 2002 and amounted to euro 10.8 million per month for 2002. The tax was not changed by the Region and for 2003 it would amount to euro 11.1 million per month, including the revaluation for the official rate of inflation as published by ISTAT. Snam Rete Gas SpA believes that this tax is illegitimate. For this reason in order to protect its interests, Snam Rete Gas filed a claim with the European Commission, aimed to opening a proceeding against the Italian Government, and with the Tax Commission of Palermo. On September 10, 2002, Snam Rete Gas filed a claim with Regional Administrative Court of Lombardia requesting the immediate application of tariffs including the tax. With ruling of December 20, 2002, the Court judged the tax at variance with European rules and therefore did not accept Snam Rete Gass claim. In December 2002, Snam Rete Gas suspended payments based on authoritative legal counsel and of said Court ruling. In January 2003 Sicily Region presented an appeal to the Council of State against the ruling of the Regional Administrative Court of Lombardia for the part that states the variance of the regional law with European rules. On July 12, 2003 the Provincial Tax Commission of Palermo discussed about the claim presented by Snam Rete Gas, however at the moment the decision is not yet made public. The Authority for Electricity and Gas, although acknowledging that the tax burden is an operating cost for the transmission activity, subjected its inclusion in tariffs to the final ruling on its legitimacy by relevant authorities. Therefore, for the 2002-2003 thermal year with decision No. 146/2002 and for the 2003-2004 thermal year with decision No. 71/2003, the Authority published two sets of tariffs: one, in force, that does not take into account the tax and the second one including it, that will be automatically applied with retroactive effect should the tax be judge legitimate.

Polimeri Europa SpA

On March 5, 2003 a criminal action started before the Court of Gela in relation to an alleged illicit treatment of FOK oil produced by the ethylene plant in Gelas refinery. The case will be discussed in December 2003. WWF Italia and Italia Nostra acted as civil part and requested for this proceeding an environmental damage for euro 50 million.

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

Eni SpA

In March 1999, the Antitrust Authority concluded its investigation started in 1997 and: (i) verified that Snam abused its dominant position in the market for the transportation and distribution of natural gas; (ii) fined Snam euro 2 million; (iii) ordered a review of these practices relating to such abuses. Snam believes it has complied with existing legislation and appealed the decision with the Regional Administrative Court of Lazio. On May 26, 1999, stating that these decisions are against Law No. 9/1991 and the European Directive 98/30/CE, this Court granted the suspension of the decision. The Antitrust Authority did not appeal this decision. The definition of this dispute is still pending.

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

With a decision presented on June 5, 2001 the Italian Antitrust Authority started an inquiry against AgipPetroli SpA, Atriplex SpA (now AgipFuel SpA) and other companies for alleged limitations to competition within the tenders offered by public transportation companies in the urban areas of Naples, Turin and Milan for the supply of gasoline for automotive use in the period 1996-2000. This proceeding intended to ascertain if the alleged agreements could be expression of a more general arrangement among companies for dividing between them the mentioned fuel supplies. On March 4, 2003 the Authoritys decision has been notified. It has verified violations for all companies involved and has fined AgipPetroli and Atriplex euro 118,000. In May 2003 Eni appealed against the decision before the Regional Administrative Court of Lazio; this proceeding is still pending.

Polimeri Europa SpA

On December 12 and 13, 2002 officers of the European Union submitted to inspection Polimeri Europa SpA with the aim of acquiring documents about the EPDM business of the Styrene and Elastomers division in relation to alleged agreements of limitations to competition between producers and suppliers of EPDM. On December 12, 2002 other two legal actions were notified in the United States: with the first one the Antitrust Jury of California summoned the deputy chairman and sales manager of Polimeri Europa Americas Inc, in relation to the alleged agreements of limitation to competition in EPDM segment; with the second some documents related to investigations about the limitations of the competition were requested to Polimeri Europa Americas Inc.

Other commitments and risks not included in the balance sheet

In order to meet the expected medium and long-term demand for natural gas in particular in the Italian market, Eni entered long-term purchase contracts with producing countries that have a residual average term of approximately 17 years. Existing contracts, which in general contain take-or-pay clauses, will ensure a total of about 67.3 billion cubic meters of natural gas per year (Russia 28.5, Algeria 21.5, Netherlands 9.8, Norway 6 and LNG from Nigeria 1.5) by 2008. The average minimum contractual withdraws represent 85% of said quantities (take-or-pay). In the medium and long-term the development of the natural gas demand in Italy and the evolution of regulatory framework might represent a risk in the management of take-or-pay contracts. In 2003, in particular, Eni evaluates that this risk concerns about one billion cubic meters recoverable in the following three years.

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 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, Enis 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 Enis 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 Enis 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 Enis 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. 471/1999 (Ronchi Decree) 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 Enis liability, if any, as against other potentially responsible parties with respect to such litigation and the possible insurance recoveries.

(million )
Taxes on:
- Italian subsidiaries	593	702
- foreign subsidiaries	1,229	1,238
	1,822	1,940

Income taxes affected Income before income taxes for the period at the rate of 36.6% compared with a statutory tax rate of 39.5% calculated by applying a 34% 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:

(million ) — Statutory tax rate	41.9		39.5
Items increasing (decreasing) statutory tax rate:
- higher foreign subsidiaries tax rate	6.0		6.2
- permanent differences	(0.3	)	(0.2	)
- tax benefit due to the application of favorable tax laws	(2.1	)	(0.7	)
- tax benefit on gains from disposals due to the application of law No. 342/2000	(4.1	)	(2.9	)

- other	(0.4	)	0.1
	(0.9	)	(2.9	)
	41.0		36.6

Tax benefit on gains from disposals due to the application of law No. 448/2001 relates to Stoccaggi Gas Italia SpA that aligned the tax basis of the assets received in 2001 by Eni SpA and Snam SpA to the conferral value by paying a substitute tax of 9%.

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, 2002 to June 30, 2003 has been added to the weighted-average number of shares outstanding in the first half of 2002; based on this criterion, the weighted-average number of shares outstanding was 3,841,931,666 and 3,781,533,963 in the first half of 2002 and 2003, respectively.

The dilutive effect of potential ordinary shares when converted into ordinary shares on Enis basic earnings per share is not material. At present, the only shares assigned for no consideration are considered and the stock options to be exercised have a book value (euro 15.216) higher than the stock market at June 30, 2003 (euro 13.369).

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

In accordance with the criteria adopted in Enis 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 2003 to generally accepted accounting principles in the USA or U.S. GAAP.

Accounts reclassified according to International GAAP

The items of Enis 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.

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

The Companys 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 2002 consolidated financial statements. With the exception of:

SFAS 143 Accounting for asset retirement obligations provides the evaluation and recording criteria for liabilities arising from the disposal of tangible long-lived assets and associated asset retirement obligation be recognized in the period in which it is incurred, if estimable, concurrent with an increase in the related assets carrying value.

92 ENI REPORT ON THE FIRST HALF OF 2003 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS PAGEBREAK

Table of Contents

| | The increase in the related assets carrying value is amortised to income over
its useful life. Upon initial adoption, a liability is recognized for existing
asset retirement obligations and the associated asset retirement cost is
capitalized as an increase to the carrying value of the assets. The recognized
liability and asset are adjusted for cumulative accretion and 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. The recognized liability is auditing to reflect
any change in the valuation of the cash flow and the execution time. |
| --- | --- |
| | Under Italian GAAP, costs related to site restoration and abandonment are
valuated annually on the basis of costs expected to be incurred for laws and
regulations, contractual obligation, general rule and policies adopted by the
Company for eventual well abandonment and site restoration. |
| | Costs related to site restoration and abandonment are accrued with the result
that the provisions are proportional to the writedowns of the investments. In
particular in the Exploration & Production segment Eni regularly accrues costs
expected to be incurred with respect to eventual well abandonment, including
costs associated with site restoration, on a unit of production basis. |
| | The effect of the difference between these two criteria is recorded in item M
of the Reconciliation between net income and Shareholders equity determined
under Italian GAAP and U.S. GAAP. |
| | The FASB issued Interpretation No. 45 Guarantors Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others (FIN 45), which provides the recording criteria for
guarantees issued or modified after December 31, 2002, in particular the
interpretation provides the recording of a liability, when the guarantee is
granted, that represents the fair value of the pledge to fulfill the obligation
assumed and generally is equal to the actual value of the commissions due by
the guaranteed. |
| | The effect of the difference between these two criteria does not result in a
significant difference. |

Reconciliation between net income and Shareholders equity determined under Italian GAAP and U.S. GAAP

The following is a summary of the adjustments to net income for the six-month periods ended June 30, 2002 and 2003 and to Shareholders equity at December 31, 2002 and June 30, 2003, that would be required if U.S. GAAP had been applied instead of Italian GAAP in these interim condensed consolidated financial statements:

The FIN 46 modifies Accounting Research Bulletin No. 51 Consolidated Financial Statement and provides standards for determining under what circumstances a variable interest entity should be consolidated by the main beneficiary of its economic result. Variable interest entities are companies in which another has an ownership, a contractual or financial relation causing obligations and profits, that changes with changes in the equitys net asset value. The requirements of FIN 46 apply immediately to variable interest entities created or purchased after January 31, 2002; the application of the rule has no material impact. The requirements apply to older entities that satisfies the provisions of FIN 46, in the first fiscal year or interim period beginning after June 15, 2003. Eni shall apply it beginning in 2004.

for contracts entered into or modified after June 30, 2003 and prospectively for hedging relationships designated after June 30, 2003. Eni shall apply this SFAS starting in fiscal year 2003.

SFAS No. 150 improves the accounting for certain financial instruments that, under previous guidance, issuers could account for as equity, but that have an obligation of reimbursement for the issuing, and requires that these instruments be classified as liabilities in statement of financial position. This Statement is effective prospectively for financial instruments entered into or modified after May 31, 2003 (the application of the rule has no impact) and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003 (Eni shall apply from the annual financial statements for 2003).

AUDITORS REPORT ON THE LIMITED REVIEW OF ENI SPA INTERIM FINANCIAL REPORTING FOR THE SIX MONTHS PERIOD ENDED 30 JUNE 2003

To the Shareholders of Eni SpA

| 1. | We have performed a limited review of the
interim financial reporting of Eni SpA for the six months period
ended 30 June 2003, consisting of consolidated balance sheet,
income statement and related comments notes. We have also ensured
that the management discussion and analysis is consistent with other
information in the interim financial reporting. |
| --- | --- |
| 2. | Our work was carried out in accordance with
the procedures for a limited review recommended by the National
Commission for Companies and the Stock Exchange (CONSOB) with
deliberation n° 10867 of 31 July 1997. The limited review
of the interim financial reporting of certain subsidiaries which, at
30 June 2003, reflected total assets constituting 21 per cent of
consolidated assets and sales revenues constituting 13 per cent of
consolidated sales revenues, excluding excise tax, is the
responsibility of other auditors. The limited review consisted
principally of inquiries of company personnel about the information
reported in the interim financial reporting and about the consistency
of the accounting principles utilised therein with those applied at
year end as well as the application of analytical review procedures
on the data contained in the interim financial reporting. The limited
review excluded certain auditing procedures such as compliance
testing and verification or validation tests of the assets and
liabilities and was therefore substantially less in scope than an
audit performed in accordance with generally accepted auditing
standards. Accordingly we do not express a professional audit opinion
on the interim financial reporting. |
| 3. | Regarding the comparative data of the
company consolidated financial statements and the interim financial
reporting of the prior year, reference should be made to our reports
dated respectively 29 April 2003 and 24 September 2002. |
| 4. | Based on our review no significant changes or
adjustments came to our attention that should be made to the interim
financial reporting identified in paragraph 1 of this report, in
order to make them consistent with the criteria for the preparation
of interim financial reporting established by article 81
half yearly report of CONSOB Regulation approved by
Resolution n° 11971 of 14 May 1999 and subsequent
modifications. |

Mr. Vittorio Mincato also underlined the importance of Enis presence in the Caspian Region, particularly in Kazakhstan, considered the new frontier of the world oil industry, illustrating the development of next coming years. According to the studies made in the Caspian Basin hydrocarbons, proved and probable reserves are estimated at around 40 billion barrels, of which 30 billions in Kazakhstan. The 70% of the Countrys reserves are concentrated in three giant fields: Kashagan, Karachaganak and Tengiz. Eni is the single operator of Kashagan, the most important discovery of the last 30 years for the oil industry, and co-operator of Karachaganak. In the period 2003-2006 production in the Country will increase by 19% per year, while Enis equity production in Kazakhstan will increase from 3.9% to about 6% of the total Enis production.
