ARTICLE 6

6.1 Pursuant to Article 3 of Law Decree 332 of May 31, 1994, converted with amendments into Law 474 of July 30, 1994, no one, in any capacity, may own company shares that entail a holding of more than 3 per cent of voting share capital.

##### Table of Contents

Such maximum shareholding limit is calculated by taking into account the aggregate shareholding held by the controlling entity, either a physical or legal person or company; its directly or indirectly controlled entities, as well as entities controlled by the same controlling entity; affiliated entities as well as people related to the second degree by blood or marriage, also in the case of a legally separated spouse. Control exists, with reference also to entities other than companies, in the cases envisaged by Article 2359, paragraphs 1 and 2 of the Civil Code. Affiliation exists in the case set forth in Article 2359, paragraph 3 of the Civil Code as well as between entities that directly or indirectly, by way of subsidiaries, other than those managing investment funds, are bound, even with third parties, in agreements regarding the exercise of voting rights or the transfer of shares or portions of third companies or, in any event, in agreements or pacts as per Article 122 of Legislative Decree No. 58 of February 24, 1998 regarding third party companies if said agreements or pacts concern at least 10 per cent of the voting capital, if they are listed companies, or 20 per cent if they are unlisted companies.

The aforementioned shareholding limit (3 per cent) is calculated by taking into account shares held by any fiduciary nominee or intermediary. Any voting rights attributable to voting capital held or controlled in excess of the maximum limit indicated in the foregoing cannot be exercised and the voting rights of each entity to whom such limit on shareholding applies are reduced in proportion, unless otherwise jointly provided in advance by the parties involved. In the event that shares exceeding this limit are voted, any Shareholders' resolution adopted pursuant to such a vote may be challenged pursuant to Article 2377 of the Civil Code, if the required majority had not been reached without the votes exceeding the aforementioned maximum limit. Shares not entitled to vote are included in the determination of the quorum at shareholders' meetings.

6.2 Pursuant to Article 2, paragraph 1 of Law Decree 332 of May 31, 1994, converted with amendments into Law 474 of July 30, 1994, as modified by Article 4, Paragraph 227, of Law December 24, 2003 no. 350, the Minister of Economy and Finance retains the following special powers to be exercised in agreement with the Minister of Productive Activities and according to the criteria contained in the Decree issued by the President of the Council of Ministers on June 10, 2004:

a) opposition with respect to the acquisition of material shareholdings by entities affected by the shareholding limit as set forth in Article 3 of Law Decree 332 of May 31, 1994, converted with amendments into Law 474 of July 30, 1994, by which – as per Decree issued by the Minister of Treasury on October 16, 1995 – are meant those representing at least 3% of share capital with the right to vote at the ordinary shareholders' meeting. The opposition is expressed within ten days of the date of the notice to be filed by the Board of Directors at the time request is made for registration in the Shareholders' Register if the Minister considers that such an acquisition may prejudice the vital interests of the Italian State. Until the ten-day term is not lapsed, the voting rights and the non-asset linked rights connected with the shares representing a material shareholding may not be exercised. If the opposition power is exercised, through a duly motivated act in connection with the prejudice that may be caused by the operation to the vital interests of the Italian State, the transferee may not exercise the voting rights and the other non-asset linked rights connected with the shares representing a material shareholding and must sell said shares within one year. Failing to comply, the law court, upon request of the Minister of Economy and Finance, will order the sale of the shares representing a material shareholding according to the procedures set forth in Article 2359-ter of the Civil Code. The act through which the opposition power is exercised may be sued by the transferee before the Regional Administrative Court of Latium within sixty days as of its issue;

b) opposition with respect to the subscription of Shareholders' pacts or agreements as per Article 122 of Legislative Decree No. 58 of February 24, 1998, involving – as per Decree issued by the Minister of Treasury on October 16, 1995 – at least 3% of the share capital with the right to vote at ordinary shareholders' meetings. In order to allow the exercise of the above mentioned opposition power, Consob notifies the Minister of Economy and Finance of the relevant pacts or agreements communicated to it pursuant to the aforementioned Article 122 of Legislative Decree No. 58 of February 24, 1998. The opposition power may be exercised within ten days as of the date of the notice by Consob. Until the ten-day term is not lapsed, the voting right and the other non-asset linked rights connected with the shares held by the shareholders who have subscribed the above mentioned pacts or agreements may not be exercised. If the opposition power is exercised through the issue of an act that shall be duly motivated in consideration of the prejudice that may be caused by said pacts or agreements to the vital interests of the Italian State, the shareholders pacts or agreements shall be null and void. If in the shareholders’ meetings the shareholders who have signed shareholders’ pacts or agreements behave as if those pacts or agreements disciplined by Article 122 of Legislative Decree No. 58 of February 24, 1998 were still in effect, the resolutions approved with their vote, if determining for the approval, may be sued. The act through which the opposition power is exercised may be sued by the shareholders who joined the above mentioned pacts or agreements before the Regional Administrative Court of Latium within sixty days as of its issue;

c) veto power with respect to resolutions to dissolve the company, to transfer the business, to merge, to demerge, to transfer the company's registered office abroad, to change the company objects and to amend the by-laws cancelling or modifying the powers indicated in this Article. The act through which the veto power is exercised shall be duly motivated in consideration of the prejudice the related resolution may cause to the vital interests of the Italian State and may be sued by the dissenting Shareholders before the Regional Administrative Court of Latium within sixty days as of its issue;

d) appointment of one Board member with no voting rights. Should such appointed Director lapse, the Minister of Economy and Finance in agreement with the Minister of Productive Activities will appoint his substitute.

3. to appoint Board members for any reason not covered by the terms of the aforementioned procedure, the shareholders' meeting will make a resolution with the majorities prescribed by the law.

17.4 The shareholders' meeting may, even during the Board's term of office, change the number of members of the Board of Directors, always within the limits set forth in paragraph 17.1 above, and make the relating appointments.

PRESS RELEASE

Eni: presentation of the effects of the adoption of International Financial Reporting Standards (IFRS)

Eni has illustrated today the effects of the adoption of International Financial Reporting Standards (IFRS)2 on its 2004 consolidated financial statements. Starting in 2005, companies with securities listed on regulated markets of Member States of the European Union are required to prepare their consolidated financial statements in accordance with international financial reporting standards.

The adoption of IFRS has no impact on Eni’s financial and industrial targets.

Following the adoption of IFRS, Eni prepared a consolidated opening balance sheet as of January 1,2004, applying the retrospective methodology3, which shows an increase in net capital employed of euro 2.6 billion with respect to the consolidated balance sheet as of December 31, 2003 (from euro 41.9 billion to euro 44.5 billion). This increase is primarily related to: (i) the review of the useful life of natural gas transport and distribution network and compression stations on a retrospective basis. This revision was carried out applying the useful life generally accepted internationally until year 1999 and the useful life assessed by the Authority for electricity and natural gas in its decision of May 2000 starting in year 2000 onwards (the impact of this revision amounts to euro 2.5 billion); (ii) the application of the weighted average cost method in the evaluation of hydrocarbon inventories instead of the previously applied Last In First Out (LIFO) method (with an impact of euro 0.8 billion); (iii) the capitalization of financial charges incurred that could have been saved if capital expenditure had not been made (with an impact of euro 0.6 billion); and (iv) the exclusion from consolidation, consistently with US GAAP, of certain joint ventures that were previously consolidated on a proportional basis (with an impact of euro 0.2 billion). These increases were partly offset by the recognition of deferred income taxes (with an impact of euro 1 billion) and the exclusion from consolidation of Saipem (euro 0.6 billion), due to the circumstance that for reporting purposes IFRS prohibit to consolidate on a line-by-line basis an affiliate of which the parent company does not hold the majority of voting rights (Eni’s share in Saipem is 43%), even though it exercises control at this affiliate’s Annual General Meetings due to a substantial ownership interest. This applies also to US GAAP.

(2) |  | Data of 2004 income statement and opening balance sheet as of January 1, 2004 restated according to IFRS may be modified after the completion of the audit by Eni’s principal auditor PricewaterhouseCoopers.
(3) |  | Under the retrospective methodology, assets and liabilities are aligned to those book values that would have been determined if IFRS had been applied from their initial recognition.

##### Table of Contents

In connection with the adjustments described, with respect to Eni’s consolidated balance sheet as of December 31, 2003, at January 1, 2004 Eni’s shareholders’ equity, including minority interest, increases by euro 2.4 billion (from euro 28.3 billion to euro 30.7 billion), net borrowings increase by euro 0.2 billion (from euro 13.5 billion to euro 13.7 billion) and net income decreases by euro 0.2 billion (from euro 7.3 billion to euro 7.1 billion) due mainly to the adjustments of the consolidated opening balance sheet as of January 1, 2004.

Eni |  | With a market capitalization amounting to over euro 69 billion as of December 31, 2004, Eni is one of the most important integrated energy companies in the world which operates in the oil and gas industry, power generation and oilfield services, construction and engineering. In these businesses it has a strong edge and leading international market positions.
STRATEGIES Growth in core business Continue the integration of core activities Focus on operating efficiency and efficacy Maximize return for shareholders |  | Eni’s strategic objective is to increase its producing scale in the oil & gas business, while, at the same time, developing midstream activities in order to support this growth. Eni intends to maintain strong hydrocarbon production growth by leveraging in particular on the contribution of large projects in the development phase and increasing efficiency both in exploration and in development/production through the selection of exploration projects, the geographic concentration of production, the rationalisation of marginal assets and assets with low development prospects, strengthening its role as operator. Special attention will be paid to reserve replacement in order to support the sustainability of long-term growth. In natural gas activities Eni intends to expand sales on European markets and implement a break-through strategy in the LNG business with the objective of attaining a worldwide presence and exploiting its natural gas reserves. Eni intends to maintain the leadership in the Italian natural gas market through a proactive approach towards the liberalization process ongoing, a higher degree of flexibility and the diversification of its import system, the gradual reduction of its presence in regulated businesses and the completion in time of the plan of expansion of power generation capacity. In downstream oil Eni intends to complete the strategic repositioning of its Agip branded distribution network in Italy, leveraging on the sale/closure of marginal service stations and developing non oil activities, while developing/consolidating its presence in target European markets where it can leverage on operating synergies and a well established brand. In refining Eni intends to increase the conversion rate and flexibility of refineries in order to produce high quality fuels anticipating the environmental requirements of new European regulations. In oilfield services, construction and engineering activities Eni intends to concentrate its presence in the strategic segment of large projects for the development of offshore hydrocarbon reserves and construction of industrial plants and infrastructure based on the application of technologies for hydrocarbon production, treatment and transmission and natural gas and heavy crudes upgrading. Key growth targets set for 2008 are the following: (i) daily hydrocarbon production of about 2 million boe corresponding to a compound average growth rate higher than 5% in the 2004-2008 period (net of the effects of portfolio rationalization); (ii) the sale of 92 billion cubic meters of gas in European markets. Overall natural gas sales, including natural gas volumes produced by the Exploration & Production segment outside Italy, are expected to reach 120 billion cubic meters in 2008 (102 billion in 2004); (iii) the reaching of an installed power generation capacity of about 5.3 gigawatts by 2007. Eni intends to reduce capital employed in non core businesses and to improve operational efficiency and efficacy targeting cost savings of about euro 3.4 billion at 2006 (over 80% of which already achieved in the 1999-2004 period). The improvement in competitive positioning will be achieved also through the integration of its core activities. Strong attention will be devoted to R&D, the key factor for the future development of the oil industry. Eni intends to invest over euro 1 billion in the next four years. Expenditure will be focused on those strategic projects through which Eni can achieve competitive advantages in the medium to long-term, in particular in the areas of exploration and recovery of hydrocarbons and of upgrading of heavy crudes and natural gas. Eni intends to support its growth strategy by implementing a four year capital expenditure plan of euro 26.9 billion, about 90% of which will be concentrated in the Exploration & Production, Gas & Power and Refining & Marketing segments.

STRATEGIES Maintain strong production growth Guarantee medium to long-term business sustainability by focusing on reserve replacement Rationalize asset portfolio Select exploration expenditure Continue to pursue efficiency improvement |  |
|  | Eni operates in the exploration and production of hydrocarbons in Italy, North Africa, West Africa, the North Sea, the Gulf of Mexico and Australia. It also operates in areas with great exploration and production potential such as the Caspian Sea, the Middle and Far East. In 2004, Eni produced 1,624,000 boe per day and, at December 31, 2004, Eni’s proved reserves totaled 7,218 million boe. Eni is pursuing an aggressive production growth strategy aimed at achieving a daily production target of about 2 million boe by 2008, which corresponds to an average annual growth rate of over 5%. Production growth will be pursued by leveraging in particular on the contribution of the great projects in the development phase in Libya, Angola, Nigeria, Iran and Kazakhstan. Eni intends to pay special attention to reserve replacement in order to guarantee the medium to long-term sustainability of its business. Eni intends to continue the rationalization of its asset portfolio, started after the purchase of British-Borneo and Lasmo, in order to increase its value by focusing on strategic areas with the highest growth potential and divesting marginal assets with limited development prospects. Exploration expenditure will be selected by balancing initiatives in areas with high mineral potential with mature projects with a lower risk profile. Eni will continue to improve its performance by searching for operating solutions with lower operating costs and synergies.

MAIN RESULTS

Hydrocarbon production was 1,624,000 boe/day with a 62,000 boe increase over 2003 (up 4% which becomes 6.4% without taking into account the effect on prices in Production Sharing Agreements - PSA); in the fourth quarter of 2004 production amounted to 1.7 million boe/day. Eni intends to maintain a strong production growth rate in the medium-term leveraging in particular on the contribution of the great projects in the development phase and targeting a production level of approximately 2 million boe/day in 2008, with a compound average growth rate of over 5%
At December 31, 2004 Eni’s proved hydrocarbon reserves were 7,218 million boe with a replacement rate of 132% without taking into account the effects of higher realized oil prices in PSAs and asset divestment; this rate declines to 91% net of these effects. In the medium-term the replacement of reserves will be supported by the relevant mineral potential of Eni’s assets located in core areas such as the Caspian Sea, West and North Africa and the Norwegian section of the North Sea. The average reserve life index was 12.1 years
Within the North Caspian Sea PSA, in March 2005 Eni’s interest in the operated project increased from 16.67% to 18.52% following the pre-emptive right exercised in May 2003 for the purchase of the share of British Gas that left the project. The development plan of the Kashagan field, approved by the Kazakh authorities on February 25, 2004, to be implemented in multiple phases aims at the production of recoverable reserves up to 13 billion barrels by means of partial reinjection of natural gas by 2008 with a total expenditure amounting to dollar 29 billion (dollar 5.4 billion being Eni’s share). At March 2005 contracts for the development of this field had been awarded for a total of dollar 6.7 billion. Production plateau is targeted at 1.2 million barrels/day. Appraisal activities performed confirmed the mineral potential of the discoveries made in the area under contract
Within the Western Libyan Gas Project production started at the onshore gas and liquid Wafa field, while development of the offshore Bahr Essalam field is underway with start-up expected in the first half of 2005. The two fields, holding recoverable reserves of approximately 1,750 million boe, will have a target production of 10 billion cubic meters/year of natural gas, of which 8 billion (Eni’s interest is 50%) will be exported to European markets through the underwater Greenstream gasline
In Angola in Block 15 (Eni’s interest 20%) in August 2004 the Hungo and Chocalho oil fields (with recoverable reserves of approximately 880 million barrels) started production within Phase A of the development project for the fields discovered in the area called Kizomba. Production is expected to peak at 43,000 barrels/day net to Eni by 2006. In this same area Phase B is underway, aimed at the development of the Kissanje and Dikanza fields with recoverable reserves of about 910 million barrels. Production is expected to start in the second half of 2005 and to peak at 43,000 barrels/day net to Eni by 2007
In Iran in October 2004 production of the natural gas and condensate South Pars field phases 4 and 5 (Eni is operator with a 60% interest) started. When fully operational production is expected to reach 20 billion cubic meters/year of gas and, through separation, one million tonnes/year of propane and butane and 80,000 barrels/day of condensates

In Kazakhstan in June 2004 within the development plan of the Karachaganak field (Eni co-operator with a 32.5% interest) the first supplies of liquids produced were delivered to the Novorossiysk terminal on the Russian coast of the Black Sea. In October liquid production reached the average level of 70,000 barrels/day net to Eni. The field, holding recoverable reserves of 3.6 billion boe, is planned to be developed in further stages with the objective of increasing natural gas production sold and maintaining peak production
In February 2004 production started from the offshore gas and liquid Bayu Undan field (Eni’s interest 12.04%) located in the international cooperation area between Australia and East Timor with recoverable reserves of over 900 million boe. The second phase of the project entails production and development of natural gas reserves through the construction of an onshore LNG plant near Darwin in Australia and the export of LNG to the Japanese market. Production is scheduled to peak at about 18,000 boe/day net to Eni in 2009
In October 2004 production of the ROD and satellites oil fields (Eni operator with a 63.96% interest in the production phase) in the Eastern Desert of Algeria with recoverable reserves of approximately 280 million barrels, started. Production makes use of the nearby Bir Rebaa oil center operated by Eni. Production net to Eni is expected to reach a 28,000 barrels/day peak in 2005
Development of the Kristin gas and oil field (Eni’s interest 9%) located in the Norwegian Sea continued. The field holds over 500 million boe of recoverable reserves, is expected to start-up in late 2005 and to peak at 19,000 boe/day net to Eni in 2006
Rationalization of Eni’s mineral portfolio, aimed at increasing its value by focusing on strategic areas with good growth potential and leaving marginal areas, continued with the sale of assets mainly in the North Sea, Italy, Azerbaijan, Gabon and Mauritania
A total of 66 new exploratory wells were drilled (29.5 of which represented Eni’s share). Overall success rate was 52.1% (57.3% representing Eni’s share). The major discoveries were achieved in the Caspian Sea (in the area of the North Caspian Sea PSA), Nigeria (onshore), Egypt (offshore in the Gulf of Suez and in the Nile Delta), Italy (onshore in Sicily and Central Italy), Norway (Norwegian Sea) and in the deep offshore of Angola and Congo

Italy

In 2004, Eni’s hydrocarbon production in Italy totaled 271,000 boe/day and represented 17% of Eni’s total production. Eni’s exploration and development interests in Italy are concentrated in the Adriatic Sea, the Central Southern Apennines, Sicily and the Sicilian offshore and the Po Valley. Natural gas production averaged 191,000 boe/day and represented approximately 70% of Eni’s hydrocarbon production in Italy. Eni’s principal natural gas fields are located in the Adriatic Sea (Barbara, Angela/Angelina, Porto Garibaldi/Agostino, Cervia/Arianna, Porto Corsini, Regina and Bonaccia which collectively accounted for 54% of Eni’s natural gas production in Italy in 2004) and in the Ionian Sea (Luna, which accounted for 9%).
Daily production of oil in Italy averaged 80,000 barrels. Eni’s three major oil fields, Val d’Agri in Southern Italy, Villafortuna in the Po Valley and Gela in Sicily, represented 75% of Eni’s total oil production in Italy in 2004. Other oil fields are Aquila in the Adriatic offshore of Southern Italy, Rospo in the Adriatic Sea, Prezioso and Vega offshore southern Sicily, Giaurone and Ragusa in Sicily.
In the Val d’Agri the fourth treatment train of the oil center was started-up and three new wells are being drilled that add up to the existing 33 (19 of these are in production). Production is expected to peak at 73,000 boe/day net to Eni in 2006.
Within its portfolio rationalization process in May 2004 Eni sold the assets in exploration and production of natural gas of Società Petrolifera Italiana pA - SPI (Eni’s interest 99%) whose production in 2003 amounted to about 5,000 boe/day, consisting mainly of natural gas.
The achievement of full production of the Val d’Agri fields and the maintenance initiatives for natural gas production will partly offset declines of mature fields.

|  | Egypt

Eni has been present in Egypt since 1954 and is the leading international oil operator. In 2004, fields operated by Eni with a production of 472,000 boe/day (200,000 net to Eni) accounted for 40% of Egypt’s total annual hydrocarbon production.

|  | In 2004 oil and condensate production averaged 94,000 barrels/day net to Eni and came mainly from the Eni operated Belayim and Ashrafi fields in the Gulf of Suez which covered 83% of Eni’s production in Egypt. In 2004, natural gas daily production averaged 106,000 boe net to Eni. The main natural gas producing interests operated by Eni are concentrated in the Nile Delta: onshore the Abu Madi and el Qar’a interests and in the Mediterranean offshore, the North Port Said (former Port Fouad), Baltim, Ras el Barr and el Temsah interests. Production from this concessions covered over 95% of Eni’s natural gas production in Egypt. In December 2004 the LNG production plant at Damietta was started-up. The plant (Eni’s interest 40%) has a treatment capacity of 7.6 billion cubic meters/year. Eni will supply 3 billion cubic meters/year of natural gas to this plant in the next 20 years. A second liquefaction train is going to be installed on the plant with the same capacity of the first one. Eni will supply its gas to this line as agreed in an intent protocol signed with the Egyptian Government in March 2005. In January 2005 the NGL plant in Port Said was started up. The plant (owned by UGDC - Eni’s interest 33%) has a treatment capacity of 31 million cubic meters of gas per day and yearly production of 330,000 tonnes of propane, 280,000 tonnes of LPG and 1.2 million barrels of condensates. In the medium term development initiatives for natural gas production, such as in particular the Temsah T4, Barboni and Baltim North offshore projects, expected to start-up in 2005, will allow to increase Eni’s hydrocarbon production in Egypt, despite the decline of mature oil fields.

|  | Libya

Eni started operations in Libya in 1959 and is the leading international operator, with oil fields operated by Eni accounting for approximately 19% of Libya’s annual oil production. In 2004 Eni’s hydrocarbon production averaged 97,000 boe/day, of these 92% was oil. The main oil fields operated by Eni are Bu-Attifel (Eni’s interest 50%) onshore in the central-eastern desert and Bouri (Eni’s interest 30%) in the Mediterranean offshore facing Tripoli which accounted for 73% of Eni’s production in Libya.
In September 2004 production of gas and liquids started at the Wafa onshore field in permit NC-169 A. By year end production reached approximately 45,000 boe/day net to Eni (about 50% was natural gas). Development of the Bahr Essalam field located in the NC-41 permit in the Mediterranean offshore is underway, production is expected to start in mid-2005 within the joint development of the two fields (Eni’s interest 50%) (see “Development Projects” below).

Eni’s principal producing fields in Nigeria are located in: (i) four onshore blocks (OML 60, 61, 62 and 63) in the Niger Delta (Eni’s interest 20%), which in 2004 accounted for 22% of Eni’s production in Nigeria; (ii) the offshore OML 125 block (Eni’s interest 50.19%), where the Abo field is located which produced over 13,000 barrels/day net to Eni. The development of other levels of the Abo field will allow to reach a production peak of 45,000 barrels/day (18,000 net to Eni) in 2007; (iii) the offshore OML 119 block (former OPL 91), operated through a service contract, where the Okono and Okpoho oil fields are located, which produced at the end of 2004 approximately 55,000 barrels/day (27,000 net to Eni).
The Bonga oil field located in offshore block OML 118, where Eni holds a 12.5% interest, is under development and start-up is expected at the end of 2005 (see “Development Projects” below).
Eni also holds a 5% interest in the 36 onshore blocks of NASE, the largest oil joint venture in the country. In 2004 production net to Eni of this joint venture accounted for about 50% of Eni’s production in Nigeria. The major development projects underway are the Cawthorne Channel and Forcados/Yokri oil fields. Peak production of oil from these fields at 90,000 barrels/day (5,000 net to Eni) is expected in 2006. Natural gas produced will be supplied to the Bonny liquefaction plant, starting in March 2005 at Cawthorne Channel (3.8 million cubic meters/day) and in October 2005 at Forcados/Yokri (2.3 million cubic meters/day).
Development initiatives are ongoing for guaranteeing natural gas supplies to the six trains of the Bonny’s liquefaction plant (three already operating, two with start-up expected in 2005) which will bring the completed plant to a production capacity of 26.5 billion cubic meters/year of LNG in 2007 (Eni’s interest 10.4%, see “Gas & Power - Development Initiatives” below). When the plant is in full operation, Eni will supply 24.1 million cubic meters/day of its natural gas.

development projects

Eni is involved in a number of development projects that will contribute to the medium and long-term growth of its hydrocarbon production. What follows is an outline of the most important development projects.

|  | Libya - Wafa and Bahr Essalam

Joint development of the gas, oil and condensate fields of Wafa, located in NC-169 A permit, 520 kilometers south west of Tripoli, and Bahr Essalam in the NC-41 permit, located in the Mediterranean offshore, 110 kilometers north of Tripoli is underway. These fields (where Eni is partner of the development with a 50% interest) hold recoverable reserves of 1.7 billion boe (about 950 million boe net to Eni). Within the development of the Wafa field 24 of the 30 planned producing wells have been completed, as well as the condensate treatment plant and the laying of the pipeline for the transmission of liquids and gas to the Mellitah treatment plant. In September the first gas shipments were made for the Greenstream gasline and the first shipments of liquids for the Mellitah plant. Within the development of the Bahr Essalam offshore field, 17 producing wells of the 27 planned were completed, the Sabratha platform is nearing completion along with the laying of the underwater pipeline for the transmission of liquids and gas to the Mellitah treatment plant. Production is expected to start in the first half of 2005. Peak production from the two fields at 240,000 boe/day (124,000 net to Eni) is expected in 2006. Eni’s share of capital expenditure amounts to approximately euro 3.1 billion only for the upstream phase.

|  | Nigeria - Bonga Project The Bonga oil field (Eni’s interest 12.5%) with recoverable reserves amounting to 577 million barrels, is situated in the OML 118 permit offshore Nigeria in waters of a depth between 950 and 1,150 meters. A total of 16 of the 34 underwater wells planned were drilled for exploiting 20 production levels. An FPSO vessel is under construction with a treatment capacity of 225,000 barrels/day and a storage capacity of 2 million barrels. Associated gas will be collected at a platform in the EA field from which it will be sent to the Offshore Gas Gathering System pipeline that in turn will carry it to the Bonny liquefaction plant. Production is scheduled to begin in late 2005 with a peak flow of about 21,000 barrels/day net to Eni in 2007. Eni’s share of the development expenditure amounts to over dollar 500 million. Kazakhstan - North Caspian Sea Within the North Caspian Sea PSA, Eni with an 18.52% interest is operator of a consortium of six international oil companies and the national Kazakh company Kazmunaygaz (KMG). The consortium changed its structure in March 2005 when British Gas left the project. The remaining members exercised their pre-emptive right and acquired British Gas’s interest (16.67%) in proportional shares and sold half of this newly acquired interest to KMG, new partner of the PSA. The consortium aims at exploration and production of hydrocarbons in the offshore area where the Kashagan field was discovered; this field is considered the most important discovery in the world in the past thirty years. On February 25, 2004 the development plan for Kashagan was approved by the Kazakh authorities.

The plan, which will be implemented in multiple phases, aims at the production of 7 to 9 billion barrels of recoverable reserves, extendible to 13 billion barrels through partial gas reinjection. Production is expected to start in 2008 at an initial level of 75,000 barrels/day and to increase to 450,000 barrels/day at the end of the first development phase. Production plateau is targeted at 1.2 million barrels/day. The total capital expenditure is estimated at dollar 29 billion (5.4 billion being Eni’s share), excluding the capital expenditure for the construction of the infrastructure for exporting production to international markets, for which various options are under scrutiny by the consortium. One of these options includes the laying of a pipeline connecting Kashagan with the Baku-Tiblisi-Cehyan pipeline now in the final phase of construction (Eni’s interest 5%). The development of the field provides for the drilling of 280 wells and the construction of platforms and artificial islands (hubs) which will collect production from satellite islands. Oil and non reinjected gas will be treated in the hubs and delivered, through two separate lines, to onshore treatment plants (located at Eskene West, near Atyrau). The oil will be further stabilized and purified; natural gas will be treated for the removal of hydrogen sulphide and will be mostly used as fuel for the production plants. The remaining amounts will be marketed. At March 2005, within the first phase of the field’s development contracts for a total of dollar 6.7 billion were awarded for the construction of infrastructure for developing the field and for offshore production (drilling, treatment and reinjection of sour gas) and onshore treatment plants. The most advanced techniques are going to be applied in the completion of the project in order to cope with high pressures in the field and the presence of hydrogen sulphide. Saudi Arabia - C area In March 2004 Eni, in a consortium with another international oil company and Saudi Aramco, was awarded an exploration license (Eni operator with a 50% interest) for exploration, development and production of natural gas in the so called C area covering approximately 52,000 square kilometers in the Rub al Khali basin at the border with Qatar and the United Arab Emirates. The project provides for geophysical surveys and the drilling of 4 exploratory wells in a period of five years. In case of commercial discoveries, the contract term of the production phase will last 25 years, with a possible extension to a maximum of 40 years. The gas discovered will be sold to the domestic market for power generation, sea water desalinization and as a feedstock for petrochemical plants. Condensates and LPG extracted from the gas will be exported to international markets. This project marks Eni’s return to upstream activities in a country where it had operated in the early 1970s. |  |

(1) |  | From January 1, 2004 in order to conform to the practice of other international oil companies, Eni unified the conversion rate of natural gas from cubic meters to boe. The new rate adopted is 0.00615 barrels of oil per one cubic meter of natural gas. In the past Eni used a rate of 0.0063 for natural gas produced in Italy and 0.0061 for natural gas produced outside Italy. The change introduced does not affect the amount of proved reserves recorded in boe at December 31, 2003 and has a negligible impact on production expressed in boe in 2004.

(2) |  | Exploration cost for each boe of new reserves discovered or proved represented by the ratio of costs incurred with respect to exploration activity and purchase of unproved property and increases in proved reserves related to improved recovery, extensions and new discoveries and revisions of previous estimates. 2001, 2002 and 2003 averages were calculated excluding purchase costs of unproved property of Lasmo in 2001 and of Fortum Petroleum in 2003.
(3) |  | For each boe of new proved reserves, represented by the ratio of the sum of costs incurred with respect to exploration and development activities and purchase of unproved property and increases in proved reserves related to improved recovery, extensions and new discoveries and revisions of previous estimates. In order to allow for an homogeneous comparison the following adjustments were carried out: (i) averages for the 2001-2004 period were calculated with the exclusion of the purchase cost of unproved property of Lasmo (purchased in 2001) and Fortum Petroleum (purchased in 2003); (ii) averages in the 2002-2004 period were calculated with the exclusion of Iranian buy-back contracts; (iii) averages in the 2003-2004 period were calculated with the exclusion of estimated costs for asset retirement obligations. Following the recently enacted Statement of Financial Accounting Standard No. 143 – Accounting for Asset Retirement Obligations – these costs are capitalized when the related capital expenditure is incurred; further adjustments of previous estimates are recognized whenever an estimate needs to be updated.

STRATEGIES Consolidate market leader position in Italy Secure and increase market share in valuable markets in Europe Develop the LNG business worldwide in order to give value to own natural gas reserves Complete plan for the construction of power stations fired with natural gas |  | gas & power natural gas Eni operates in the supply, transmission, distribution and sale of natural gas. In 2004, Eni sold 84.5 billion cubic meters of natural gas (including own consumption1 and Eni’s share of sales of affiliates2). Eni’s transmission network in Italy through medium and high pressure pipelines is about 30,000-kilometer long. Outside Italy Eni owns transportation rights on over 5,000 kilometers of pipelines. Eni is pursuing the development of sales in the rest of Europe and in the LNG business in order to compensate the lower growth opportunities on the domestic market, due to the limits imposed to operators by the sector regulation. In Italy, Eni intends to maintain sales volumes within the regulatory limits through the optimal allocation of supplies between direct sales in Italy and in the rest of Europe and by using natural gas at its own electricity generation plants and, at the same time, leveraging on the expected consumption growth. Eni’s marketing policy will aim to customer satisfaction by means of market segmentation, the integration of marketing actions and structures and the expansion and customization of services offered to customers. The development of sales on the European gas market will leverage on the competitive advantage of Eni’s diversified portfolio of supply contracts and extensive gas pipeline network which allows the supply of natural gas from several sources as well as the long standing relationships with producing countries. Eni intends to consolidate its presence in target markets (Iberian Peninsula, Germany and Turkey) and develop sales in markets with significant growth and profitability prospects (in particular France and the United Kingdom). Eni also intends to expand its presence in LNG in order to increase the value of its own natural gas reserves in West and North Africa, in the Far East and in Latin America. Eni intends to participate in projects concerning natural gas liquefaction and regasification, targeting sales of 12 billion cubic meters in 2008. Based on contracts signed and actions defined or planned, Eni expects to sell about 92 billion cubic meters of natural gas on European markets in 2008.

MAIN RESULTS

With the starting of operations of the Greenstream (Eni’s interest 75%) underwater gasline in October 2004, supplies of natural gas from Libyan fields started and, when fully operational in 2006, will reach 8 billion cubic meters/year (of which 4 billion net to Eni), already booked under long-term contracts with operators of this segment
Eni continued its program for developing its electricity generation capacity targeted at 5.3 gigawatts of installed power by 2007 with total capital expenditure amounting to approximately euro 2.2 billion (of which 1.6 were already expensed). When fully operational the new gas fired combined cycle plants will allow to consume over 6 billion cubic meters/year of natural gas produced by Eni. In 2004, about 1.3 gigawatts were installed at the Ferrera Erbognone, Ravenna and Mantova power stations, thus bringing Eni’s total installed capacity to 3.3 gigawatts
Within its strategy of international expansion in natural gas, Eni and its partners in Nigeria LNG (Eni’s interest 10.4%) have approved expenditure plans for the construction of the sixth train for LNG production at the Bonny treatment plant, that, when fully operational in 2007, will have a production capacity of 26.5 billion cubic meters/year. This initiative will allow Eni to fully exploit its natural gas reserves in Nigeria
In March 2005 Eni signed a preliminary agreement for the purchase of a share of regasification capacity corresponding to 4 to 6 billion cubic meters/year of LNG at the Cameron terminal, under construction on the coast of Louisiana (USA) for a term of 20 years. The terminal is expected to be completed in 2008 with an initial capacity of 15 billion cubic meters/year. This deal provides Eni with access to the North American gas market which will absorb part of Eni’s African reserves
In January 2005 the first LNG shipping was delivered to the Damietta treatment plant (Eni’s interest 40%). When fully operational the plant will produce approximately 7 billion cubic meters/year of LNG mainly directed to the Spanish market
Eni sold shares corresponding to 9.054% of Snam Rete Gas share capital in partial execution of Law No. 290/2003 that prohibits companies operating in the natural gas business to hold interest higher than 20% in companies owning natural gas transmission network from July 1, 2007
In January 2005 Eni agreed a 14 year contract, starting in 2006, for the supply of 1.2 billion cubic meters/year of natural gas to the German company Wingas. The gas will be delivered at Eynatten at the German-Belgian border

the Italian natural gas system

In the next decade world consumption of natural gas is expected to increase, due to: (i) the continuous improvement in technologies applicable to all phases of natural gas chain and capable of reducing distances between mineral assets and consumption areas (LNG, GTL, TAP); (ii) the higher environmental compatibility of natural gas as compared to other hydrocarbons in particular in electricity generation; (iii) the expected demographic, economic and social developments; (iv) the steady increase in natural gas reserves. Europe represents one of the areas with the highest growth rate, where the average increase in consumption is expected to be about 3% per year.
Given the recent regulatory and organizational developments, the Italian national natural gas system takes part in the structural change ongoing in Europe with the prospect of a single market for energy. In this context Italy will be able to make good use of its geographical position and its double integration with the European internal market and the Mediterranean area. Eni has the know-how and experience necessary for becoming a leader in this process of European development.
One of the new features of the development process ongoing in Europe is the importance acquired by international hubs, the major interconnection points in international transmission networks where volumes of natural gas are traded on a spot basis. The development of these hubs, currently located in Great Britain, Belgium and Germany, can be attributed to the progressive cancellation of the territorial destination clause in supply contracts, to the new regulations on third party access to transmission networks and to increased gas availability in markets. Hubs represent an opportunity for Eni for selling increasing gas volumes, as Eni can take advantage from its diversified supply portfolio and the flexibility provided by long-term supply contracts.
The demand for natural gas in Italy
With consumption amounting to 80 billion cubic meters in 2004 (increasing by over 3% over 2003) Italy is the third European market for natural gas after Great Britain and Germany. In 2004, about 20% of natural gas requirements were met through domestic production (including natural gas volumes withdrawn from storage), while imports covered 80%.
Eni expects natural gas consumption in Italy to reach about 91 billion cubic meters in 2010, corresponding to an annual average increase of about 2%. The share of natural gas on total domestic energy requirements is expected to reach nearly 36% as compared to the present 33%.
Most of this increase will concern natural gas used in electricity generation, because of the significant advantages of the use of natural gas in combined cycle plants, thanks to its lower investment cost, higher yields and reduced polluting emissions as compared to other fuels. Demand is expected to increase also from residential and commercial users, due to the increased use of natural gas in residential space heating in households and services, in large tertiary firms and as vehicle fuel.

Supply of natural gas
In 2004, Eni’s requirements for natural gas are met for over 83% with supplies from foreign countries (mainly Algeria, Russia, the Netherlands and Norway) under long-term contracts. The remaining part is covered by gas supplied by Eni’s Exploration & Production segment. Eni is a party of long-term purchase contracts with producing countries that currently have a residual average term of approximately 16 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 Nigeria 1.5) by 2008. These contracts concern total volumes amounting to approximately 1,088 billion cubic meters.
Transmission, dispatching and regasification
Transmission, dispatching and regasification activities in Italy are carried out by Snam Rete Gas, a company listed on the Italian Stock Exchange (in which Eni holds a 50.07% interest). Eni’s primary transmission network was conferred to Snam Rete Gas in July 2001 in implementation of Legislative Decree No. 164/2000 concerning the Italian natural gas market, which provides for the separation of transmission, dispatching and regasification activities from all other activities in the natural gas segment. This Decree also establishes that transport activity qualifies as a public concern activity and consequently is regulated.
The Italian natural gas transmission system is made up of a national pipeline network and a regional pipeline network for a total length of 32,190 kilometers, of which 30,545 owned by Eni.

The Italian national transmission network is made up of high pressure trunklines, mainly with a large diameter, which carry natural gas from the entry points to the system – import lines, storage sites and main Italian natural gas fields – to the linking points with the regional transmission network. The national network includes also some interregional lines reaching important markets.
The regional transmission network is made up of the remaining lines and allows the transmission of natural gas to industries, power stations and local distribution companies of the various local areas served.
At December 31, 2004 the national pipeline network owned by Eni extended for 8,196 kilometers. Underground pipelines have a maximum diameter of 48 inches and carry natural gas at pressures of 24 to 75 bars. The underwater pipeline crossing the Messina Strait has a diameter of 20 to 26 inches and carries natural gas at a pressure equal to or higher than 115 bars.
The major pipelines interconnected with import trunklines that are part of Eni’s national network are:

|  | for natural gas imported from Algeria and Libya:
| • |  |  | two lines3 with a 48/42-inch diameter, each approximately 1,500-kilometer long, including the smaller pipes that cross underwater the Messina strait, which link Mazara del Vallo (on the Southern coast of Sicily) to Minerbio (near Bologna). These lines are linked to the import pipelines that carry natural gas from Algeria through the Sicily Channel and from Libya through the Gela-Enna pipeline and the underwater Greenstream gasline. The pipeline transmission capacity at the Mazara and Gela entry points is approximately 90 million cubic meters/day;
| for natural gas imported from Russia:
| • |  |  | two lines with 48/42/36/34-inch diameters extending for a total length of approximately 1,000 kilometers that are linked to the Austrian network in Tarvisio and cross the Po Valley reaching Sergnano (near Cremona) and Minerbio. The pipeline transmission capacity amounts to 84.4 million cubic meters/day. The pipeline is going to be upgraded by the laying of a third 264-kilometer long line (of which 199 kilometers started operations at the end of 2004);
| for natural gas imported from the Netherlands and Norway:
| • |  |  | two lines, with a 48/34-inch diameter, 301-kilometer long extending from the Italian border at Passo Gries (Verbania), point of connection with the Swiss network, to the node of Mortara, in the Po Valley. The pipeline transmission capacity amounts to 57.5 million cubic meters/day.

(3) |  | At the end of 2004 the 69-kilometer long section of the triple line started operations. By 2007 a total of 290 kilometers are expected to be on triple line.

In 2004 Eni’s national network increased by 203 kilometers due to the entry into service of: (i) a new line connecting Gela, entry point of the Greenstream gasline from Libya, to the national network near Enna. The 36-inch diameter pipe covers 66 kilometers and has a transport capacity of 25 million cubic meters/day; (ii) the completion of a 30-inch diameter line connecting Pontremoli to Parma for the transmission of natural gas from the Panigaglia regasification terminal to northern Italy (70 kilometers); (iii) a 32-kilometer line upgrading the pipeline for importing natural gas from Russia; (iv) the sections from Palmi to Martirano and from Campochiaro to Sulmona as part of the upgrade of the Transmed pipeline through a third line for a total length of 53 kilometers.
Eni’s regional transmission network is made up of pipes with smaller diameter than the national lines for a total length 22,349 kilometers. These pipes carry natural gas at pressures between 5 and 12 bars, between 12 and 24 bars and between 24 and 75 bars. In 2004, Eni’s regional network increased by 222 kilometers due to the entry into service of new lines, upgrades and of various connections to end users.
Eni’s system is completed by: (i) 11 compressor stations with a total power of 625 megawatts; (ii) 5 marine terminals linking underwater pipelines with the on-land network at Mazara del Vallo, Messina and Gela in Sicily and Favazzina and Palmi in Calabria.
The control room of the dispatching system is located in San Donato Milanese and oversees and monitors the whole transmission network in cooperation with peripheral units. In 2003 this system obtained the ISO 9001-2000 certification. Peripheral units are represented by 8 districts that monitor the transmission network through 69 centers that guarantee operation, maintenance and control of the whole system. Each unit is responsible for operations in accordance with technical specifications and applicable laws and regulations.
In addition to the international pipeline transmission system, natural gas enters Eni’s system also through the Panigaglia (Liguria) LNG terminal, which receives liquefied natural gas (LNG) carried by tanker ships. This terminal is the only one in Italy, at its maximum it can input 3.5 billion cubic meters/year into the transmission network. LNG is downloaded from tanker ships and stored, then vaporized in a regasification plant made up of cryogenic pumps and submerged flame vaporizers. When it has recovered the

gaseous state, natural gas is input in the transmission network. In 2004, volumes of LNG regasified amounted to the equivalent of approximately 2.1 billion cubic meters of natural gas. Upgrading of this terminal is underway by means of an enhancement of the boil-off gas recovery system.
In 2004 a total of 80 billion cubic meters of natural gas were input in the national network, of these 65% were owned by Eni.
The Italian natural gas system is supplied for about 80% with imported gas, transmitted to Italy through a network of international high pressure pipelines for a total of over 4,300 kilometers; in which Eni owns transportation rights, in particular:

• |  | the TENP pipeline, 968-kilometer long (a 500-kilometer long single line and a 468-kilometer long doubling line) with transit capacity4 of 44 million cubic meters/day and four compression stations, transports natural gas from the Netherlands through Germany, from the German-Dutch border of Bocholtz to Wallbach at the German-Swiss border;
• |  | the Transitgas pipeline, 291-kilometer long, with one compression station, which transports natural gas from the Netherlands and from Norway crossing Switzerland with its 165-kilometer long main line and a 71-kilometer long doubling line, from Wallbach where it joins the TENP pipeline to Passo Gries at the Italian border. It has a transit capacity of 61 million cubic meters/day. A new 55-kilometer long line from Rodersdorf at the French-Swiss border to Lostorf, an interconnection point with the line coming from Wallbach was built for the transport of Norwegian gas;
• |  | the TAG pipeline, 1,018-kilometer long, made up of two lines, each about 380-kilometer long and a third line 258-kilometer long, with a transit capacity of 81 million cubic meters/day and three compression stations, which transports natural gas from Russia across Austria from Baumgarten, the delivery point at the border of Austria and Slovakia, to Tarvisio, point of entry in the Italian natural gas transport system;
• |  | the TTPC pipeline, 742-kilometer long, made up of two lines each 371-kilometer long with a transit capacity of 78 million cubic meters/day and three compression stations, which transports natural gas from Algeria across Tunisia from Oued Saf Saf at the Algerian border to Cap Bon on the Mediterranean coast where it links with the TMPC pipeline;
• |  | the TMPC pipeline for the import of Algerian gas, 775-kilometer long, made up of five lines each 155-kilometer long with a transit capacity of 101 million cubic meters/day which crosses underwater the Sicily Channel from Cap Bon to Mazara del Vallo in Sicily, the point of entry into the Italian natural gas transport system;
• |  | the Greenstream pipeline for the import of Libyan gas, 520-kilometer long, with a transit capacity of 24.4 million cubic meters/day which crosses underwater the Mediterranean Sea from Mellitah to Gela in Sicily, the point of entry into the Italian natural gas transport system. The pipeline started operations in October 2004, when fully operational it will transport 8 billion cubic meters/year (of these 4 billion are Eni’s share).

Eni plans to upgrade the TAG and TTPC pipelines in order to adjust import capacity to the expected increase in demand in Italy.
Eni holds a 50% interest in the Blue Stream underwater pipeline linking the Russian and Turkish coast of the Black Sea. When fully operational, this 774-kilometer long pipeline with a transmission capacity of 49 million cubic meters/day, will transport 16 billion cubic meters per year in 2010 (Eni’s share 8 billion) of Russian natural gas to be sold on the Turkish market (see “Development Projects” below).

Sales in Italy
In 2004, Eni’s natural gas sales in Italy amounted to 54.1 billion cubic meters (including own consumption). The Italian natural gas market is made up of three main segments: residential and commercial, industrial and thermoelectric. Customers can be divided into three groups: (i) high consumption final users directly linked to the national and regional natural gas networks; (ii) final customers such as residential and commercial users, hospital, schools, public utilities, small enterprises located in urban centers supplied by wholesalers through low pressure lines; (iii) wholesalers (mainly local distribution companies and distributors of natural gas for automotive use) purchasing natural gas to sell it to final customers.
In 2004, Eni’s natural gas sales to wholesalers amounted to 14.2 billion cubic meters (down 7.7% over 2003).
Natural gas consumption in the industrial segment amounted to approximately 22.6 billion cubic meters (29% of total final consumption), with a 3.5% increase over 2003. In 2004, Eni’s sales of natural gas to industrial users amounted to about 12.4 billion cubic meters (down 5.9% over 2003).
Natural gas consumption in the thermoelectric segment amounted to approximately 28 billion cubic meters (35% of total final consumption), with an approximately 9% increase over 2003. In 2004, Eni’s sales of natural gas to thermoelectric users amounted to 15.9 billion cubic meters (up 5.9% over 2003).
Natural gas consumption in the residential and commercial segment amounted to over 28 billion cubic meters (36% of total final consumption), with a 1% decrease over 2003 due to the effect of weather conditions. Following the merger of Italgas Più Eni manages directly over 5 million residential customers and in 2004 sales Eni’s sales amounted to 7.4 billion cubic meters (up 0.8% over 2003).
As a consequence of decisions of the Antitrust Authority (so called gas release plan) Eni sold 0.5 billion cubic meters to operators in the natural gas segment.
In 2004 own consumption amounted to 3.7 billion cubic meters and concerned essentially supplies to EniPower (2.6 billion cubic meters) and to Eni’s petrochemical plants and refineries.
Eni’s commercial structure is organized by branches in Italy in order to react promptly and efficiently to the requirements of large and medium enterprises, thermoelectric producers and wholesalers. Eni’s marketing policy towards clients of those segments provides for customized contractual options including, among others, various price formulas and types of indexations aimed at controlling price volatility, on the basis of purchase needs of clients. Eni’s commercial policy leverages on: (i) a dedicated sales team; (ii) a contact center business; (iii) a website providing new services of analysis and monitoring of costs and gas offtake; (iv) a portfolio of over 50 different kinds of technical assistance and consultancy services.
As a consequence of the merger with Italgas Più SpA, leader in Italy in retail sales of natural gas, Eni integrated its structure with a network of channels dedicated to households, public entities, the tertiary sector, condominiums, and small enterprises: the traditional counters, a network of contact centers, the website with an online opportunity for managing one’s contract and the network of franchisors under the “Assistenza Italgas Più” brand name, that in 2004 were 150.
Customers are offered a wide range of services. Residential users can contact the franchisor for supplies, installation and ordinary and extraordinary maintenance of their heating systems, while condominiums, public administrations and enterprises are offered a turn-key service for all what concerns their heating requirements.

Distribution activities
Distribution involves the delivery of natural gas to residential and commercial users in urban centers through low pressure networks. Eni, through its 100% subsidiary Italgas and other subsidiaries, is engaged in the distribution activity in Italy serving 1,236 municipalities through a low pressure network consisting of over 47,000 kilometers of pipelines at December 31, 2004. Legislative Decree No. 164/2000 concerning the opening up of the natural gas market in Italy defines distribution a public service which is subject to regulation and its management is entrusted to natural gas companies by local governments exclusively under bid procedures. Concessions existing at the coming into force of the Decree and awarded with a bid procedure expire on December 31, 2012; all other concession expire on December 31, 2007 (with an optional one-year extension in case of public interest).
Sales in the rest of Europe
Eni signed seven long-term supply contracts with operators in the natural gas sector who in turn import supplied volumes of natural gas in Italy. These contracts, when fully operational in 2006, will enable Eni to supply about 15 billion cubic meters of natural gas per year, including 8 billion cubic meters (Eni’s share 4 billion) from the Libyan fields. Until the production from Libyan fields comes on stream, these supplies will be covered with gas derived from Eni’s wide and diversified portfolio of supply contracts.
In 2004 sales in European markets amounted to 28.5 billion cubic meters, including sales through affiliates; in particular: (i) 17.5 billion related to sales in target markets, among which the Iberian Peninsula (4.3 billion, of which 1.4 billion to the Spanish electric company Iberdrola and 0.70 billion cubic meters of LNG treated at the liquefaction plant of Nigeria LNG Ltd - Eni’s interest 10.4%), Germany (4 billion), Hungary (3.4 billion), Northern Europe (2.9 billion), Turkey (1.7 billion), France (0.70 billion cubic meters of LNG treated at the liquefaction plant of Nigeria LNG); (ii) over 10.4 billion related to the above-mentioned supply contracts with Italian operators in the natural gas sector.
Sales outside Europe

development projects

Eni is engaged in various development projects concerning the sale of natural gas in European markets and in the LNG business in order to compensate the lower growth opportunities on the domestic market, due to the limits set to operators by the sector regulation. In these European markets Eni can leverage on a favorable competitive positioning ensured by gas availability, access to infrastructure, long standing relations with producing countries and knowledge of markets. Eni intends to develop its presence also in the LNG business which provides interesting growth prospects, leveraging on the value of its assets, on its participation in liquefaction projects aimed at exploiting its natural gas reserves (mainly in North and West Africa, the Far East and Australia) and on the purchase of interests in regasification terminals located in strategic consumption markets (United States, United Kingdom, Far East).

> GERMANY

Eni is present on the German natural gas market since late 2002 through GVS (Gasversorgung Süddeutschland GmbH) in which it acquired a 100% interest in joint venture with the German electricity operator EnBW. GVS is the sixth operator in the German gas market and the fourth in terms of volumes transported. Through a 1,863-kilometer long gas pipeline network (of these 1,750 are owned and 113 are managed) it transports and markets about 7 billion cubic meters of gas per year to local distribution companies serving about 750 municipalities in the south-western areas of the country.
In January 2005 Eni agreed a 14 year contract, starting in 2006, for the supply of 1.2 billion cubic meters/year of natural gas to the German company Wingas. The gas will be delivered at Eynatten at the German-Belgian border.
In 2008 Eni expects to sell over 6 billion cubic meters, of which 3.3 billion cubic meters of natural gas through GVS, corresponding to a 6% market share.

Portugal
Eni operates on the Portuguese market through Galp Energia (Eni’s interest 33.34%). Eni and its other partners (the Portuguese Government with 34.81% and Energias de Portugal with 14.27%) are planning a restructuring of Galp’s activities. In 2004, Galp Energia sold about 4.4 billion cubic meters of natural gas to about 820,000 customers through a network of high, medium and low pressure pipelines about 11,700-kilometer long. Galp’s assets include among others interests in two import infrastructures, the Transmaghreb pipeline and the Sines LNG terminal, which provide an access to the Iberian market.
Spain
Eni operates on the Spanish market through the Unión Fenosa Gas group (Eni’s interest 50%, the remaining 50% being held by Unión Fenosa SA) active in natural gas supply and sale to final users and to power generation companies. In 2004 natural gas sales of Unión Fenosa Gas amounted to 1.2 billion cubic meters. Unión Fenosa Gas active in LNG through an 80% interest in a liquefaction plant with a capacity of over 7 billion cubic meters per year, located at Damietta on the Egyptian coast that started operations in January 2005, and through a 7.36% interest in a liquefaction plant under construction in Oman, which is expected to start operations in 2006. In addition, it holds an 18.9% and a 42.5% interest in the El Ferrol and Sagunto regasification plants under construction, managed by the Reganosa and Saggas companies. The Sagunto plant is expected to start operations at the end of 2005, while the El Ferrol plant is expected to start operations in 2006.
Through Unión Fenosa Gas, Gas de Portugal and the development of direct sales, Eni targets to sell about 8 billion cubic meters by 2008 in the Iberian Peninsula, corresponding to an 18% market share.

> TURKEY - BLUE STREAM

Eni and Gazprom hold equal shares in Blue Stream Pipeline Company BV, which operates the Blue Stream transport system, that links the Russian (Dzhubga) to the Turkish (Samsun) coast of the Black Sea. The gasline transports natural gas produced in Russia which is sold jointly by Eni and Gazprom in Turkey to the Turkish company Botas under a long-term contract. In 2004 Botas withdrew approximately 3.2 billion cubic meters of natural gas (of which 1.6 billion were Eni’s share). Volumes transported and marketed will increase progressively in future years and are targeted to about 16 billion cubic meters per year (8 billion net to Eni) in 2010.

> LNG

Eni is a party in various initiatives in the area of LNG. What follows is a description of the main ones.
Nigeria
Eni holds a 10.4% interest in Nigeria LNG Ltd that manages the Bonny liquefaction plant for the treatment and export of LNG. The plant, made up of three treatment trains with an overall capacity of 11.2 billion cubic meters/year of liquefied natural gas is undergoing an upgrade by means of the installation of three further trains expected to be completed between 2005 and 2007, which will increase its capacity to 26.5 billion cubic meters by 2008.
Eni also takes part in a study for the construction of a liquefaction terminal at Brass on the Nigerian coast, about 100 kilometers west of Bonny. The plant will have a capacity of approximately 14 billion cubic meters/year of LNG (and 1.2 million tonnes/year of LPG). Natural gas supplies to this plant will derive from Eni’s production.
Australia
Eni holds a 12.04% interest in the Bayu Undan project (see: “Exploration & Production - Development Projects”, above) which provides for the construction of a liquefaction plant for the production of approximately 4.5 billion cubic meters/year of LNG destined to the Japanese market.

power generation |  | Eni, through EniPower, is one of the major operators in electricity generation on the Italian market. Operating since 2000, EniPower owns power stations located at Eni’s sites in Brindisi, Ferrera Erbognone, Livorno, Mantova, Ravenna, Ferrara and Taranto with installed capacity in operation of approximately 3.3 gigawatt at December 31, 2004. In 2004, Eni sold 17 terawatthour of electricity, of which about 13.85 produced by EniPower, corresponding to over 5% of the Italian market, and 10 million tonnes of steam. Eni is implementing a plan for expanding its electricity generation capacity targeting in 2007 an installed capacity of 5.3 gigawatts, corresponding about 10-11% of electricity generated in Italy at that date. Planned expenditure amounts to euro 2.2 billion, of this 1.6 already expensed. In 2004 the Ferrera Erbognone and Ravenna power stations started their full commercial operation, while construction is still underway at Brindisi, Mantova and Ferrara. High efficiency, low environmental impact, reduced expenditure and construction times are the main features of these plants, which show interesting profitability prospects due to the expected increase in demand for electricity and the ability to operate in co-generation (combined electricity and steam generation). The co-generation mode has been acknowledged by the Authority for Electricity and Gas as a production mode that entails priority on the national dispatching network and the exemption from the purchase of “green certificates”5. Eni estimates that given the same amount of energy (electricity and heat) produced, EniPower power stations will allow to reduce emissions of carbon dioxide by approximately 11.8 million tonnes, as compared to emissions caused by conventional power stations. This amount corresponds to approximately 8% of the total carbon dioxide generation of the Italian thermoelectric segment in 2002. These power stations will also generate negligible amounts of particulate and sulphur oxides as well as very low emissions of nitric oxides. EniPower intends to become a cost leader in the Italian electricity industry thanks to the high technology content and optimal size the plants it is building. When fully operational in 2008, consumption of natural gas of Eni’s plants will reach over 6 billion cubic meters/year, supplied by Eni.

| (5) |  | Article 11 of Legislative Decree No. 79/1999 concerning the opening up of the Italian electricity market obliges importers and producers of electricity from non renewable sources to input into the national electricity system a share of electricity produced from renewable sources set at 2% of electricity imported or produced from non renewable sources exceeding 100 gigawatt. Calculations are made on total amounts net of co-generation and own consumption. This obligation can be met also by purchasing volumes or rights from other producers employing renewable sources (the so called “green certificates”) to cover all or part of such 2% share. Legislative Decree No. 387/2003 established that from 2004 to 2006 the minimum amount of electricity from renewable sources to be input in the grid in the following year be increased by 0.35% per year. The Minister for Productive Activities, with decrees issued in consent with the Minister of the Environment will define further increases for the 2007-2009 and 2010-2012 periods.

STRATEGIES Improve the competitive positioning of the refining system Enhance Italian distribution network by promoting customer loyalty and developing non oil activities Launch innovative fuels in terms of environmental results and engine performance Continue expansion in selected European regions Intensify efficiency and competitivity improvement actions |  | Eni is engaged in the refining and marketing of refined products mainly in Italy and the rest of Europe. In distribution, with its Agip and IP brands, Eni is market leader in Italy. In 2004, Eni’s sales of refined products amounted to 53.5 million tonnes, of which 30.7 million tonnes in Italy. At December 31, 2004 Eni’s intake processing (on own account and for third parties) in wholly-owned refineries was 26.8 million tonnes with full utilization of balanced capacity. The scenario of refining in Europe in future years will be characterized by: (i) decline in gasoline consumption in favor of diesel fuel, related to the renewal of the car fleet that favors diesel cars; (ii) progressive substitution of fuel oil with natural gas; (iii) increase in differential between light and heavy crudes that favors high conversion capacity refineries; (iv) the evolution of European fuel specifications as concerns sulphur content (50 ppm from 2005 and 10 ppm from 2009). In this context Eni intends to strengthen its competitive positioning by increasing the conversion capacity and flexibility of its refineries in order to upgrade its production to meet European environmental standards and differentiate its range of products dedicated to specific market segments. Eni intends to continue the process of requalification and strategic repositioning of its distribution network in Italy in order to reach European standards in terms of average throughput and services to customers. In this area Eni intends to increase its offer of diversified fuels with low environmental impact and to promote customer loyalty initiatives and develop non oil activities. In the rest of Europe Eni intends to strengthen its position in target areas where it can obtain logistical and operating synergies and exploit the well-known Agip brand. Sales volumes will be increased by buying or leasing well equipped and high throughput services stations and building new ones. Eni will intensify its efforts for efficiency improvement in all its business lines.

refining

Eni is engaged in refining activities in Italy and owns interests in refineries in Germany and the Czech Republic with a total refining capacity (balanced with conversion capacity) of 34 million tonnes (equal to 681,000 barrels/day) with 29.2 million tonnes capacity in Italy.

> ITALY

Eni’s refining system in Italy is made up of five wholly owned refineries and a 50% interest in the Milazzo refinery in Sicily. In March 2005 Eni sold its 28% interest in Erg Raffinerie Mediterranee SpA (Priolo refinery) to Erg SpA. Eni’s wholly owned refineries in Italy had a balanced capacity of 25.2 million tonnes (equal to 504,000 barrels/day), corresponding to over a fourth of Italian capacity and a conversion capacity of approximately 16.4 million tonnes, with a 59.2% conversion equivalent capacity, one of the highest in Europe.
In 2004 total intake processing on own account amounted to 33.4 million tonnes (of these 8.1 million tonnes on refineries belonging to third parties, in particular Milazzo, Priolo and Saras). Total intake processing on wholly owned refineries amounted to 26.8 million tonnes with full utilization of balanced capacity.
Eni intends to consolidate its refining activity by: (i) increasing flexibility and conversion capacity with the aim of producing fuels adequate to demand and meeting European environmental standards, in particular Eni aims at increasing the conversion index of its wholly and partiality owned refineries in Italy from 61% in 2004 to 67% in 2008; (ii) reducing FOB refining capacity in order to dampen its exposition to the volatility of margins, typical of low complexity refineries located far from their end markets. The constant improvement in Eni’s refining system will allow it to increase its integration with the Exploration & Production segment in order to increase intake volumes of own crudes. The share of own crudes processed will increase from 33% in 2004 to over 36% in 2008.
Each of Eni’s Italian refineries is specialized based on its logistical configuration, geographic location and integration with other Eni business segments.
Sannazzaro, with a balanced primary refining capacity of 160,000 barrels/day and an equivalent conversion index of 42.5% is one of the most efficient refineries in Europe. Located in the south-west of the Po Valley, at the confluence of the rivers Po and Ticino, it produces mainly gasolines, gasoil and other light products for the supply of markets in north-western Italy, Switzerland and Bavaria. Besides its primary distillation plants, this refinery contains two catalytic reforming plants used to increase the octane number of gasolines, an isomerization plant and three desulfurization plants, which allow a high degree of flexibility of production related to market and environmental conditions. The conversion plants are: a fluid catalytic cracker (FCC), an HDCK middle distillate conversion, and a visbreaking thermal conversion unit. This refinery processes mainly oil from Russia, Africa and the North Sea, oil from Eni’s nearby Villafortuna field and, more recently, CPC Blend crude oil from the Caspian Sea carried through the CPC pipeline. From a logistical standpoint this refinery is located along the route of the Central Europe Pipeline, which

links the Genova terminal with French speaking Switzerland and Bavaria. In 2004 works continued for the completion of the tar (heavy residue from visbreaking) gasification plant that will produce syngas that will be used to fire the nearby EniPower power station at Ferrera Erbognone.
In the medium term Eni plans an increase in the conversion capacity of this refinery by building a new hydrocracking unit (for the production of high quality diesel fuel, kerosene for aircrafts and lubricant bases for the Livorno refinery). Capital expenditure is expected to amount to euro 170 million.
Gela, with a balanced primary refining capacity of 100,000 barrels/day and an equivalent conversion index of 140.1% represents an upstream integrated pole with the production of heavy crudes obtained from nearby Eni fields offshore and onshore Sicily, while downstream it is integrated with Eni’s nearby petrochemical plants. Located on the southern coast of Sicily, it manufactures fuels for automotive use and residential heating purposes, as well as petrochemical feedstocks. Its high conversion level allows it to minimize the yield of fuel oil and semi-finished products. Besides its primary distillation plants, this refinery contains the following plants: an FCC unit with advanced technology for the conversion of low grade feedstocks and two coking plants for the vacuum conversion of heavy residues. All these plants are integrated in order to process heavy residues and feedstocks and manufacture valuable products. This refinery also contains modern residue and exhaust fume treatment plants which allow the complex to comply with the most exacting environmental standards. Oil and oil products are handled on land and by sea.
Taranto, with a balanced primary refining capacity of 90,000 barrels/day and an equivalent conversion index of 71.6%, can process a wide range of crudes and semi-finished products with great operational flexibility. It mainly produces fuels for automotive use and residential heating purposes for the south-eastern Italian markets. Besides its primary distillation plants, this refinery contains desulfurization plants and conversions plants such as: a two-stage thermal conversion plant (visbreaking/thermal cracking) and an RHU conversion plant, one of the most advanced plants in the world that allows to convert high sulphur content residues into valuable products with low environmental impact. It processes most of the oil produced in Eni’s Val d’Agri fields carried to Taranto through the Monte Alpi pipeline; in 2004 a total of 2.3 million tonnes of this oil were processed.
In the medium term Eni plans an increase of the conversion capacity of this refinery through the conversion of one of the four RHU reactors into a hydrocracking plant for the manufacture of high quality diesel fuel and virgin naphtha destined to Eni’s Brindisi petrochemical plant. Planned expenditure amounts to approximately euro 60 million.
Livorno, with a balanced primary refining capacity of 84,000 barrels/day and an equivalent conversion index of 11.4%, manufactures mainly gasolines, fuel oil for bunkering, specialty products and lubricant bases. Besides its primary distillation plants, this refinery contains two gasoline treatment plants, an isomerization plant and an octanization plant for the manufacture of highly environmental friendly gasolines, as well an advanced solvex cycle for lubricant manufacture. Its pipeline links with the local harbor and with the Florence storage sites allow the Livorno facility to operate with great efficiency as concerns reception, handling and distribution of products.
Porto Marghera, with a balanced primary refining capacity of 70,000 barrels/day and an equivalent conversion index of 22.8%, produces mainly gasolines and other light products for the supply of markets in north-eastern Italy, Austria, Slovenia and Croatia. Besides its primary distillation plants, this refinery contains a gasoline treatment plant, octanization plants and a two-stage thermal conversion plant (visbreaking/thermal cracking) for increasing yields of valuable products.

> ITALY

In 2004 Eni sold 13.8 billion liters of fuels and its market share was 36.3%. At December 31, 2004, Eni’s retail distribution network consisted of 7,244 service stations (60% of which under the Agip brand).
Eni is implementing a process of requalification and strategic repositioning of its distribution network in Italy with the objective to reach European standards in terms of throughput and services provided to customers. To this end it intends to promote initiatives aimed at developing customer loyalty and developing non oil activities (catering and convenience stores) and to offer a range of different fuels. Eni targets for 2008 an Agip branded network consisting of 4,270 service stations with average throughput of about 2.8 million liters.
In 2004 Eni started to sell the new BluSuper gasoline, which guarantees better engine performance and efficiency and reduces polluting emissions, thanks to its high antidetonating power resulting from a higher octane number (98 as compared to 95 of ordinary gasolines) and its lack of sulfur. BluSuper complements BluDiesel, sold since 2002, and is part of Eni’s strategy to improve the quality of its fuels, anticipating their compliance with EU regulations (mandatory from 2009) and targeting its offer to customers’ requirements, leveraging on Eni’s integrated refining-logistics-distribution system. In 2004 BluSuper sales amounted to 83 million liters. At year end Agip branded service stations selling BluSuper were about 1,000 corresponding to about 23% of the network.
In 2004 markets confirmed the success of BluDiesel, with sales of 1.2 billion liters (up 37.8% over 2003), corresponding to 21% of total diesel fuel volumes sold on the Agip branded network (16% in 2003) and to 7% of all diesel fuel sales on the Italian market (5.2% in 2003). At the end of 2004 about 3,900 Agip branded service stations were selling BluDiesel, corresponding to about 90% of the Agip network.
In 2004 Eni carried out a Do-It-Yourself campaign which allowed customers accessing self-service outlets provided with an electronic card to obtain price discounts or gifts in proportion to the total amount of purchased fuel, plus a bonus for the most loyal customers and long-distance drivers. At year end the number of cards distributed exceeded 3.8 million. The amount of fuel purchased with these cards was about 30% of all fuel sold on Agip branded service stations. Service stations participating in this initiative were approximately 3,200. Points registered by fidelity cards increased by about 50% over 2003.
Eni continued also its AgipMaxi promotional initiative addressed to truck drivers who purchase diesel fuel at the approximately 800 Agip branded service stations participating in the program. Active fidelity cards were over 38,000.
The improvement in the quality of service to customers led to a further expansion of the automation process of the domestic network. At December 31, 2004 nearly all Agip branded service stations were provided with a corporate credit card system.
In 2004 Eni continued the development of the European Multicard Routex paying card

addressed to professional transport (transporters and car fleets) with sales of 1.4 billion liters (up 9.2% over 2003), while the number of customers provided with this card increased by about 3,000 to 45,000 users at year end. Multicard is used internationally and is part of the international Routex consortium, made up by four oil companies.
Eni continued the development of its non oil retail activities aimed at promoting the development of its network in line with European standards, such as the diffusion of self-service facilities, high-tech car care systems, catering services and innovative commercial outlets. To this end Eni owns master franchisor rights with exclusive rights for the oil sector for some international brands of the restaurant and catering sector.
In 2004, a total of 103 new affiliations were added to the AgipCafè® branded outlets launched in 2003, and by year end 207 franchises were active, while 2 new Pans & Co outlets and 7 new convenience stores under the “SpazioAgip” brand name were opened. A total of 88 new car-wash facilities were opened on Agip branded service stations.
In the next four years Eni intends to continue the development of its non oil activities and expects to provide 70% of its Agip branded network with these structures by 2008 (50% in 2004).

> OFFSHORE CONSTRUCTION

Saipem has gained a sound competitive positioning in the segment of large EPIC projects for the development of offshore hydrocarbon fields by integrating its technological and operational skills, supported by a world-class fleet, with engineering and project management capabilities acquired on the market (among which Bouygues Offshore, Moss Maritime, Petromarine, Idpe). The demand for these services is expected to increase in particular in West Africa, the Caspian Sea, the Far East, Russia and Asia Pacific, in accordance with plans for the development of hydrocarbon reserves announced by the major oil companies.
The development of offshore fields, especially in the deep offshore, is more and more frequently performed by means of floating production units (FPU), where Saipem has an excellent competitive positioning, while the demand for installation of fixed platforms is slowly declining. Among FPUs, FPSO vessels1 offer the best development prospects due to their storage capacity, which allows to develop fields remote from transmission infrastructure, and to their versatility, which allows at the end of the useful life of a field to relocate vessels on other fields thus expanding their useful life.
Saipem is recognized as one of the leading international companies for the design, procurement and installation of fixed platforms, in particular in the segment of ultra heavy lifting, thanks to the technical features of its vessels. It is a world leader in the laying

Saipem provides offshore drilling services to oil companies mainly in key areas such as West Africa, the Middle East, the North Sea and North Africa. Its offshore drilling fleet consists of 10 advanced vessels properly equipped for its primary operations and some drilling plants installed on board of fixed offshore platforms. The technical features of its vessels allow Saipem to keep significant market positions in the most complex areas of deep and ultra deep waters. One of its most important offshore drilling vessels is the Saipem 10000, designed to explore and develop hydrocarbon reservoirs operating in excess of 3,000 meters water depth in full dynamic positioning. The ship has a storage capacity of 140,000 barrels and can maintain a steady operating position without anchor moorings by means of 6 computerized azimuth thrusters, which offset and correct the effect of wind, waves and current in real time. Capital expenditure for building this ship amounted to about dollar 300 million. The vessel is operating in ultra deep waters (over 1,000 meters) in West Africa.
Other relevant vessels are Scarabeo 5 and 7, third and fourth generation semi-submersible rigs able to operate at depths of 1,900 and 1,200 meters of water respectively.

skills. The leasing of an FPSO represents an alternative to direct expenditure for oil companies. West Africa is the market with the highest expected growth rates due to the number of development projects announced or started-up by oil companies. Saipem’s main vessels are: (i) FPSO Firenze, a tanker ship which, after its conversion into a floating production and storage vessel, has been installed in Eni’s Aquila field, in the Adriatic Sea, where it operates at a depth of 850 meters; (ii) FPSO Mystras that has been installed since January 2004 in the Okono and Okpoho oil fields operated by Eni with a 100% interest in the deep offshore of Nigeria. Saipem intends to expand its market share in this business and plans to upgrade its offer by designing new generic FPSO vessels, designed and equipped in direct cooperation with the client in order to identify standard features that make the vessel easily employable in more than one development projects according to the client’s portfolio of assets.
ONSHORE CONSTRUCTION
Eni operates in the construction of plants for hydrocarbon production (separation, stabilization, collection of hydrocarbons, pumping stations, water injection) and treatment (removal and recovery of sulphur dioxide and carbon dioxide, fractioning of gaseous liquids, recovery of condensates) and in the installation of large onshore transmission systems (pipelines, compression stations, terminals).

particular long distance pipelines represent one of the favorite systems for linking production areas with their end markets, despite the increasing competition from other transport modes (LNG, GTL, etc). The main operation areas are the Caspian Sea, Russia’s Far East, Africa and the Middle East. Saipem intends to consolidate its competitive positioning in this segment by exploiting in particular the opportunities provided by remote areas, characterized by the lack of infrastructure, where it can leverage on its distinctive ability to operate in difficult contexts and to manage complex projects. Saipem is also capable of providing onshore services complementary to offshore operations, which represents a competitive advantage for the development of projects in areas such as the Caspian Sea. ONSHORE DRILLING Saipem operates in this area as main contractor for the major international oil companies. Onshore drilling is conducted through 47 facilities located in Saudi Arabia, North Africa, Central Asia, Peru, Venezuela and Italy. Some of these facilities can drill to 10,000-meter depths in high pressure and high temperature environments. Saipem intends to focus its activities in areas where it has been present for a long time and to search opportunities in areas with proved development prospects such as Central Asia, the Middle East and North Africa. Saipem can also exploit the opportunities provided by the emergence of new logistically demanding remote areas lacking infrastructure that require the ability to operate in hostile environmental conditions. |  |

Business areas

> PLANTS

Oil & Gas. Snamprogetti has the world class know-how to carry out the most complex and technologically advanced projects in the area of plants for hydrocarbon production, natural gas treatment and upgrading, (LNG; recovery and fractioning of natural gas liquids). Based on the capital expenditure plans announced by oil companies, Snamprogetti expects a strong growth in the demand for services in these areas. In particular the segment of transport and treatment of natural gas seems the most dynamic due to the progressive globalization of demand and supply of natural gas. Snamprogetti intends to consolidate its know-how in natural gas treatment, where capital expenditures for expanding liquefaction and regasification capacity of about 100-120 million tonnes/year of LNG (equivalent to 140-170 billion cubic meters/year) are expected in the next four years.
Refining. In this area Snamprogetti has a sound competitive positioning in conventional areas, having built a number of grass root refineries and refining units, and is a leader in the segment of plants for the hydroconversion and hydrotreatment of heavy residues and distillates. Snamprogetti intends to seize the growth opportunities of the business of plants for heavy residue conversion and production of clean fuels. Growth in this business is supported by the wider availability of heavy crudes and by the increasingly stringent environmental requirements on emissions established worldwide. At Eni’s Taranto refinery the first demonstration plant with 1,200 barrels/day capacity based on the Eni Slurry Technology is nearing completion. This technology has a high strategic value and

|  | aims at meeting the increasing demand for upgrading of heavy crudes and non conventional crudes (tar sands) and for conversion of refining residues (see: “Innovative Technologies” below). Chemical complexes. Snamprogetti is active in the area of plants for the conversion of natural gas (syngas, GTL, hydrogen, ammonia, methanol and urea) and gas-to-chemicals (ethylene and ethane derivatives). The demand for syngas is markedly increasing for its application in the gas to liquids field for the manufacture of high quality diesel fuel from natural gas; in this segment, where syngas is a critical element Snamprogetti is at the technological frontier also thanks to its subsidiary Haldor Topsøe. Snamprogetti holds a sound position in the design and construction of plants for the production of nitrogen-based fertilizers and high-octane additives for gasoline (MTBE, ETBE, TAME and iso-octene/iso-octane), based on proprietary technologies. Snamprogetti intends to strengthen its competitive position in the segment of world scale plants for ammonia and urea production, demand for which is supported by increasing consumption in Asia, with capital expenditure in new capacity concentrated in areas where gas has a competitive price (Middle East, Africa, Latin America). Snamprogetti intends to seize the opportunities for the construction of plants for the manufacture of ethylene and petrochemical products from ethane, where relevant capital expenditure is expected in areas where feedstocks have a low price (especially the Middle East). In cooperation with an international partner Snamprogetti is engaged in the development of a technology for the manufacture of styrene from ethane (see: “Innovative Technologies” below). Energy. Snamprogetti is active in the design and construction of combined cycle power stations also fired with refinery residues (IGCC - Integrated Gasification Combined Cycle). Snamprogetti intends to make use of the relevant know-how it acquired in the construction of EniPower power stations searching for new projects in Italy and outside Italy. FIELD UPSTREAM FACILITIES AND PIPELINES Snamprogetti holds relevant competitive positions in the design and construction of pipelines for the transmission of hydrocarbons, collection networks and upstream plants (construction of primary separation plants, gas and water injection systems, compression and pumping stations), the demand for which is expected to grow. Snamprogetti is developing new advanced technologies for high pressure transport of natural gas aimed at the exploitation of reserves located in remote areas (see: “Innovative Technologies” below). INFRASTRUCTURE Snamprogetti is active in the field of design and construction of great infrastructure in Italy. In particular it is working at the completion of the high speed/high capacity train tracks from Milan to Bologna. The Italian market for great infrastructure shows interesting prospects after the approval of a 10-year plan for the construction of public works by the Italian Government. The types of works, their size, the introduction of simpler and faster authorization procedures, the modes of implementation of projects based on their critical variables (time, cost, quality and profitability) and the acknowledgement of the role of General Contractor are the elements on which Snamprogetti bases its efforts to win orders in this area, also in order to reduce the cyclicality of the demand for services from the oil and petrochemical industries. AQUATER - ENVIRONMENTAL ACTIVITIES Snamprogetti, through its Aquater - Environmental Activities division, is active in the field of projects for environmental remediation and reclamation, protection of the soil and integrated water systems in the framework of the optimization of compatibility of industrial development and environmental protection. The division provides a wide range of engineering services for the soil, the environment and natural resources and is active both as a consultant and as a main contractor in the area of environmental remediation, reclaiming of plants, waste management, water purification and civil works.

new technologies

Eni is aware of the key role innovative technologies play in the future development of the hydrocarbon industry, it therefore intends to develop key technologies that can contribute to the establishment of competitive advantages and to the meeting of its long to medium term growth and profitability objectives. Research projects are selected according to a strict evaluation of their return and are carefully monitored in light of the maximization of the value of Eni’s project portfolio.
In the next four years Eni intends to invest over euro one billion in R&D, balancing projects aimed at reaching short term objectives for business units with group-wide projects aimed at strengthening medium to long term business sustainability. In particular the main focus of Eni’s R&D lines are: (i) reserve replacement and reduction of mineral risk; (ii) production from non conventional hydrocarbon reserves and optimal management of reserves with high hydrogen sulphide and sulphur content; (iii) expansion in the natural gas market and utilization of associated gas and gas located in remote areas; (iv) improvement of quality and performance of fuels in light of the evolution of engines to increasingly perfected and efficient systems with lower impact on air quality; (v) efficient use of fossil fuels through an improvement in refining yields and an optimal use of each fuel with reduced environmental impact; (vi) mitigation of greenhouse effect, through the capture and geological sequestration of carbon dioxide.
Eni intends to search global alliances in order to participate in research projects that have a longer horizon than the four-year plan. Follows a brief description of the main techniques applied or under development.
Hydrocarbon exploration and production

> INNOVATIVE TECHNOLOGIES FOR SUBSOIL SURVEY

In order to prepare a geological model of fields as near as possible to reality aimed at the simulation and monitoring of fields, Eni developed significant industrial applications of highly innovative technologies. The main objective of these technologies is the reduction of mineral risk and the optimization of processes for extracting and recovering hydrocarbons.
New and relevant developments have been reached in the 3D Common Reflection Surface (CRS) Stack, Deep Migration Phase Shift Plus Interpolation (PSPI) and Kirchoff True Amplitude (KTA) proprietary technologies, which allowed to obtain significantly higher results than conventional technologies. The relevant improvement of the final seismic imaging and the higher density and precision of information on the characteristics of subsoils of fields (in Italy, the Gulf of Mexico, West and North Africa) allowed to reduce the risk associated to the definition of geological models in the field’s development phase.
Significant developments and industrial applications derived also from advanced technologies for modeling and monitoring fields, such as: the integrated workflow for the characterization and study of fractured systems, cross-well seismics, 4D or time lapse seismics to monitor the behavior of producing fields over time.

|  | DRILLING OF ADVANCED WELLS Eni developed and applied at industrial level a series of technologies that allow to drill highly complex wells with greater operating efficiency. In particular, lean profile drilling, developed and patented by Eni, is applied in deep vertical and deviated wells especially in high pressure and high temperature environments allowing a reduction in time and costs and in environmental impact as it reduces the volume of rock handled. Wells obtained with this technique are high quality and low risk. The technique basically consists in reducing to a minimum the tolerance between the diameter of wells and their lining columns while keeping the production casing unchanged. The verticality and direction of the hole are guaranteed by innovative tools such as “Vertitrack” (former SDD, straight-hole drilling device) and “Autotrack” developed and applied by Eni in cooperation with Baker-Hughes. Lean drilling was successfully applied both in Italy (Val d’Agri, Trecate) and outside Italy (Tunisia, Algeria and Egypt) and entailed significant benefits such as higher safety and higher savings of costs and time. The application in Val d’Agri is a record lean drilling in highly deviated wells (a 13"3/8 casing in a 14"3/4 hole with inclination up to 60°). In deep water drilling Eni’s innovative proprietary technology is the dual casing running which allows for simultaneous drilling of the first two superficial holes of a deep water well, the simultaneous lowering of the superficial casings and the cementing. The application of this technology allows for a significant reduction in time and costs and a perfect verticality of the two casings and the well head.

> INNOVATIVE TECHNOLOGIES FOR THE TREATMENT OF FLUIDS

In the field of transmission and treatment of hydrocarbons Eni developed and applied innovative technologies with particular attention to multi-phase fluids (water, oil and/or gas) in order to optimize production and reduce its environmental impact. In particular, Eni successfully tested at its Cavone oil center a pilot plant for the removal of oils from layer waters which allows to reduce the residual concentration of hydrocarbons in water to less than 10 ppm, starting from an initial content of over 1,000 ppm. The system is based on the use of adsorbing polymers capable first to capture oil particles and then to release them favoring their coalescence and making them easier to separate. The system is currently being engineered in order to make it useable on platforms. Another ongoing project aims at optimizing new design centrifugal systems for the separation of water from oil and for the confirmation of innovative technologies for removing soluble organic compounds.
Also in the field of multiphase pumping Eni is applying innovative technologies as an alternative to traditional production systems in marginal fields, fields located in frontier areas or difficult contexts such as deep waters. The multiphase technology becomes extremely useful, in terms of economic benefits, in offshore applications where the possibility to transport production from the wells over long distances allows to transfer processing activities on existing facilities and infrastructure, thus significantly reducing technical costs for the development of fields. Infield applications of multiphase pumping have been recently installed offshore and onshore in the United Kingdom and Tunisia with other partners in order to obtain a higher recovery of hydrocarbons.
Integrated projects and corporate development projects

> MANAGEMENT OF HYDROGEN SULPHIDE AND SULPHUR

The R&D project for the optimal management of reserves with high content of hydrogen sulphide and sulphur started in 2003 is continuing. The project aimed at developing innovative technologies and/or advanced processes able to manage the disposal and possible exploitation of high amounts of sour gas and sulphur that are co-produced with

hydrocarbons, while respecting safety and the environment. In particular innovative processes for the separation of hydrogen sulphide and its conversion into plain sulphur and the storage and/or use of this sulphur are in the development phase. In parallel innovative processes are being studied for the reinjection of hydrogen sulphide into the field and its monitoring.

> ENI SLURRY TECHNOLOGY

At Eni’s Taranto refinery the testing is ongoing of a Demonstration Plant with a 1,200 barrels/day capacity based on Eni Slurry Technology (EST) which, when demonstrated in 2005, will provide Eni with an important competitive lever. This is a strategically relevant technology because it allows a more economic use of heavy crudes and the total transformation of a barrel of oil into high quality fuels, avoiding the fatal production of fuel oil, otherwise destined to be used in electricity generation in Rankine cycles with low yield and high environmental impact. The subtraction of fuel oil from thermoelectric use will indirectly favor the penetration of combined cycle gas fired plants with high efficiency and very low environmental impact.

> TRANSMISSION: TAP PROJECT

The TAP Project (High Pressure Transmission) aims at developing reliable technologies for making the transmission via pipeline of relevant amounts of natural gas from production areas to consuming markets economically viable, thus favoring the sale of gas produced by Eni’s upstream activities. This project was started in May 2003 and is aimed at developing the most advanced long distance, high capacity, high pressure and high grade solutions with relevant targets related to: (i) distances over 3,000 kilometers; (ii) natural gas volumes to be transported of about 20-30 billion cubic meters/year; (iii) pressure equal to or higher than 15 Mpa and (iv) use of high and very high grade steel (e.g. X100). In 2004 the construction phase started of an experimental pilot pipeline with 48-inch diameter in the utmost resistant steel, which will significantly contribute to reduce the time necessary for the development of the technology. Within this project also the construction of a 10-kilometer long portion of pipe in X80 steel started.

> CONVERSION OF NATURAL GAS INTO LIQUIDS

Aim of the project is to exploit the relevant natural gas reserves that are not extracted because too far from end markets, through their conversion into high quality, synthetic oil products totally sulphur and aromatic free. At Eni’s Sannazzaro pilot plant, research on production of wax by means of Fischer-Tropsch technology was completed and validation activities are underway.

> INNOVATIVE FUELS: CLEAN DIESEL FUEL PROGRAM

In 2004 Eni started to sell the new BluSuper gasoline, which guarantees better engine performance and efficiency and reduces polluting emissions, thanks to its high antidetonating power resulting from a higher octane number (98 as compared to 95 of ordinary gasolines) and its lack of sulfur. BluSuper complements BluDiesel, sold since 2002, and is part of Eni’s strategy to improve the quality of its fuels, anticipating their compliance with EU regulations (mandatory from 2009) and targeting its offer to customers’ requirements, leveraging on Eni’s integrated refining-logistics-distribution system.
Eni also continued R&D activities of various process lines aimed at improving the quality of its gasoil pool, among these a process for oxidating desulphurization in order to manufacture sulphur-free gasoil at competitive prices.

> GHG PROGRAM: GEOLOGICAL SEQUESTRATION OF CARBON DIOXIDE

R&D in the field of environmental protection led to the start-up of an integrated research program Green House Gases (GHG), aimed at verifying the feasibility of the geological sequestration of CO2 in depleted fields and salty aquifers. As for the former, the potentially employable fields have been identified and characterized. The definition of a pilot project

will be completed in 2005. As part of the program, Eni decided to participate in the second phase of the CO2 Capture project aimed at finding practical solutions for the capture and sequestration of CO2.

> HYDROGEN PROJECT

Eni’s interest in this field is aimed at the creation of a portfolio of technologies that may be employed in the production of hydrogen as energy vector from various primary energy sources. In 2004 Eni started the construction of a pilot plant for the development of a new type of multi-fuel reformer based on catalytic oxidation with low contact time of liquid and gaseous hydrocarbons. The aim is to produce hydrogen at competitive costs also in medium to small sized plants with high flexibility related to refinery feedstocks available.

> STYRENE FROM ETHANE

In cooperation with Dow Chemical Co Eni is developing an innovative technology for the production of styrene monomer from ethane and benzene, that, compared to conventional techniques based on ethylene, will allow to reduce production costs, as confirmed by the demonstration plant, and to free the manufacturer from the need to locate the plant near a petrochemical complex producing ethylene, obtaining also greater flexibility.

supplemental oil and gas information1

Oil and natural gas reserves
Proved oil and gas reserves are the estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under technical, contractual, economic and operating conditions existing at the time. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions. Proved reserves exclude royalties and interests owned by others.
Proved developed reserves are proved reserves that can be estimated to be recovered through existing wells with existing equipment and operating methods.
Proved undeveloped oil and gas reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for completion.
Additional oil and gas reserves expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing natural forces and mechanisms of primary recovery are included as proved developed reserves only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.
The estimates of Eni’s reserve quantities have been prepared in accordance with applicable U.S. Securities and Exchange Commission regulation. The estimates of proved reserves, developed and undeveloped are based on data prepared by Eni.
Eni operates under PSAs in several of the foreign jurisdictions where it has oil and gas exploration and production activities. In countries where Eni operates under PSAs, proved reserves are shown in accordance with Eni’s economic interest (pursuant to PSA contract terms) in the oil and gas reserve quantities estimated to be recoverable in future years. Such reserves include estimated quantities allocated to Eni for recovery of costs, income taxes owed by Eni but settled by its joint venture partners (which are state-owned entities) out of Eni’s share of production, and Eni’s net equity share after cost recovery. Proved oil and gas reserves associated with PSAs represent 43%, 46% and 51% of total proved reserves as of year-end 2002, 2003 and 2004, respectively, on an oil-equivalent basis.
Proved reserves include the volume of natural gas used for own consumption and volumes of natural gas held in certain Eni storage fields in Italy. Proved reserves attributable to these fields include: (i) the residual natural gas volumes of the reservoirs; (ii) natural gas volumes from other Eni fields input into these reservoirs in subsequent periods. Proved reserves do not include volumes owned by or acquired from third parties. Gas withdrawn from storage is produced and thereby detracted from proved reserves when it is sold to third parties.
Numerous uncertainties are inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures. The accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgement. Results of drilling, testing and production after the date of the estimate may require substantial upward and downward revision. In addition, changes in oil and natural gas prices could have an effect on the quantities of Eni’s proved reserves because the estimates of reserves are based on prices and costs at the date when such estimates are made. Reserves estimates are also subject to revision as prices fluctuate due to the cost recovery feature under certain PSAs.
The following table presents yearly changes in estimated proved reserves, developed and undeveloped, of crude oil (including condensate and natural gas liquids) and natural gas.

(1) |  | From January 1, 2004 in order to conform to the practice of other international oil companies, Eni unified the conversion rate of natural gas from cubic meters to boe. The new rate adopted is 0.00615 barrels of oil per one cubic meter of natural gas. In the past Eni used a rate of 0.0063 for natural gas produced in Italy and 0.0061 for natural gas produced outside Italy. The change introduced does not affect the amount of proved reserves recorded in boe at December 31, 2003 and has a negligible impact on production expressed in boe in 2004. Due to this change of the conversion rate of natural gas, revisions of previous estimates as of December 31, 2004 include a downward revision of 18 million boe for Italy and an upward revision of 7, 2, 3 and 2 million boe for North Africa, West Africa, North Sea and rest of world, respectively.
(2) |  | Data at December 31, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004 include 136.2, 143.7, 144.2, 139.4, 134.8, 139.8, 129.9, 139, 133.2 and 128.4 million boe of natural gas in storage in Italy, respectively.

(1) |  | Results of operations from oil and gas producing activities including services for the modulation of gas supply due to seasonal swings in demand, represent only those revenues and expenses directly associated with Eni’s oil and gas production. These amounts do not include any allocation of interest expense or corporate overhead and, therefore, are not necessarily indicative of the contributions to consolidated net earnings of Eni. Such income taxes have been calculated by applying the tax rate of the country where Eni operates to the pretax income from exploration and production activities. Revenues and income taxes include taxes due in PSA’s where Eni’s tax liability is paid by the State Company on behalf of Eni.

Standardized measure of discounted future net cash flows
Estimated future cash inflows represent the revenues that would be received from production and are determined by applying year end prices of oil and gas to the estimated future production of proved reserves. Future price changes are considered only to extent provided by contractual arrangements. Estimated future development and production costs are determined by estimating the expenditures to be incurred in developing and producing the proved reserves at the end of the year. Neither the effects of price and cost escalations nor expected future changes in technology and operating practices have been considered.
The standardized measure is calculated as the excess of future cash inflows from proved reserves less future costs of producing and developing the reserves, future income taxes and a yearly 10% discount factor.
Future cash flows include annual revenue payments from Eni’s Gas & Power segment and other transport and distribution gas companies which represent payments for modulation services to support demand delivery capability. Such capability is provided through utilization of gas withdrawn from producing fields and injected into depleted gas fields as storage.
Future production costs include the estimated expenditures related to the production of proved reserves plus any production taxes without consideration of future inflation. Future development costs include the estimated costs of drilling development wells and installation of production facilities, plus the net costs associated with dismantlement and abandonment of wells and facilities, under the assumption that year end costs continue without considering future inflation. Future income taxes were calculated in accordance with the tax laws of the countries in which Eni operates.
The standardized measure of discounted future net cash flows, related to the preceding proved oil and gas reserves, is calculated in accordance with the requirements of Statement of Financial Accounting Standard No. 69. The standardized measure does not purport to reflect realizable values or fair market value of Eni’s proved reserves. An estimate of fair value would also take into account, among other things, the expected recovery of reserves in excess of proved reserves, anticipated changes in future prices and costs and a discount factor representative of the risks inherent in producing oil and gas.
