San Donato Milanese, May 11, 2007 - Eni, the international oil and gas company today announces its group results for the first quarter of 2007 (unaudited).
Paolo Scaroni, Chief Executive Officer, commented:
“The first quarter 2007 was affected by weaker oil prices, a strong euro, and low seasonal gas and product sales due to unusually mild weather conditions. Despite these, Eni managed to deliver excellent results among the best in the European oil & gas sector. In the first months of 2007 we undertook a successful acquisition campaign purchasing attractive oil assets which will make an important contribution to our growth strategy in the following years.”

##### Table of Contents

Financial highlights

- Adjusted operating profit was euro 5.25 billion, down 5.1% from a year ago and dragged down by weaker operating performance of the Exploration & Production division due primarily to the negative impact of the euro’s appreciation against the dollar (up 9%), lower production volumes sold, and lower realisations. This was partly offset by an improved operating performance delivered by Eni’s downstream businesses and the Engineering & Construction division;
- Adjusted net profit was down 9.3% to euro 2.68 billion, mainly as a result of the reduced operating profit and higher net financial expenses owing to losses on the fair value evaluation of certain financial derivative instruments;
- Net cash provided by operating activities stood at euro 5.56 billion, allocated as follows: euro 2.01 billion to capital expenditure, euro 203 million to the repurchase of own shares and euro 2.92 billion to reduce net borrowings;
- Capital expenditure of euro 2.01 billion, up 50.2% from a year ago, related mainly to development of oil and gas reserves, exploratory projects and the upgrade of both the international and domestic gas transportation infrastructure, and refineries;
- Return on Average Capital Employed (ROACE)1 calculated on an adjusted basis for the twelve-month period ending March 31, 2007 was 22.7% (21.8% for the twelve-month period ending March 31, 2006);
- Ratio of net borrowings to shareholders’ equity including minority interest – leverage1 – decreased to 0.09 from 0.16 at the end of 2006.

Operational highlights and trading environment

Fourth Quarter |  |  |  | First Quarter

2006 |  |  |  | 2006 |  | 2007 |  | % Ch.

|  | Key operating data |  |  |  |  |  |  |  |  |
1,796 |  | Production of hydrocarbons |  | (kboe/d) |  | 1,827 |  | 1,734 |  | (5.1 | )

4,132 |  | Natural gas |  | (mmcf/d) |  | 3,920 |  | 4,061 |  | 3.6 |
26.93 |  | Worldwide gas sales |  | (bcm) |  | 31.20 |  | 28.14 |  | (9.8 | )
1.06 |  | of which: upstream sales |  |  |  | 1.12 |  | 1.07 |  | (4.5 | )
7.79 |  | Electricity sold |  | (TWh) |  | 7.73 |  | 7.61 |  | (1.6 | )
3.13 |  | Retail sales of refined products in Europe |  | (mmtonnes) |  | 2.93 |  | 2.88 |  | (1.7 | )

- Oil and natural gas production for the quarter averaged 1.73 mmboe/d, a decrease of 5.1% compared with the first quarter of 2006. This result was impacted by the loss of production at the Venezuelan Dación oilfield (down 60 kbbl/d) which was a result of the unilateral cancellation of the service agreement for the field exploitation by the Venezuelan State Oil Company PDVSA effective April 1, 2006, and the continuing social unrest in Nigeria. When factoring in these two events, production was at similar levels to the first quarter of 2006. Increases in productivity in Libya, Kazakhstan and the Gulf of Mexico were offset by mature fields in decline, particularly in Italy, and by facility shutdowns;

- Eni’s worldwide natural gas sales were down 9.8% to 28.1 bcm due to lower European gas demand owing to unusually mild winter weather, partially offset by a growth achieved in some target markets (in particular Spain and Turkey);

- The trading environment was affected by lower oil prices with Brent crude prices averaging $57.75 per barrel, down 6.5% compared to the first quarter of 2006, and the appreciation of the euro over the dollar (up 9.0%). These negatives were partially offset by: (i) favourable trends in energy and exchange rate parameters used in determining purchase and selling prices of natural gas; (ii) an increase in refining margins on the Brent crude marker (up 3.7%), and (iii) higher sales margins on petrochemical products.

Portfolio developments

- Gulf of Mexico: Eni acquired interests in exploration and production activities owned by Dominion Resources. Following this deal, Eni expects its proved and probable reserves in this region to increase by 222 mmboe and a 75,000 boe/day additional oil and gas production in the period 2007-2010 on average, starting from July 1, 2007. Eni will retain operatorship of most of the exploration and production assets acquired.
- Acquisition of gas assets ex-Yukos: as part of the strategic alliance signed with Gazprom, Eni in partnership with Enel (60% Eni, 40% Enel) was awarded 100% of OAO Arctic Gas Company, ZAO Urengoil Inc, OAO Neftegaztechnologia which own large hydrocarbon reserves, mostly gas reserves. Eni also acquired 20% of OAO Gazprom Neft. Gazprom has an option to acquire a 51% interest in these acquired companies and the entire 20% interest in OAO Gazprom Neft.
- Acquisition of operated assets in Congo: Eni acquired interests in exploration and production onshore activities operated by Maurel&Prom in Congo. This will increase Eni’s proved reserves of 126 mmboe and a 28,000 boe/day additional hydrocarbon production is expected in 2010.
- Acquisition of a retail station network in Central-East Europe: Eni purchased 102 retail fuel stations from ExxonMobil Central Europe located in Czechia, Slovakia and Hungary, and related additional marketing activities.
- Acquisition of an additional interest in Nikaitchuq field in Alaska, achieving a 100% interest. The ongoing field development, with start-up planned late in 2009, is expected to produce additional proved and probable reserve of approximately 70 mmboe.
- Memorandum of Understanding with Sonangol for the acquisition of a 13.6% interest in the Angola LNG Limited Consortium (A-LNG) committed to build a LNG plant with a 5 mmtonnes capacity.

Outlook for 2007

The outlook for Eni in 2007 remains positive, with key business trends for the year as follows:
- Production of liquids and natural gas is forecast to remain at the same level as 2006 (in 2006 oil and gas production averaged 1.77 mmboe/d). Additional production expected in the second half of the year from acquired properties in the Gulf of Mexico and Congo and the expected build-up in gas production in Libya will enable Eni to recover the first quarter decline in production due to escalating social unrest in Nigeria and the loss of the Dación oilfield in Venezuela;
- Sales volumes of natural gas worldwide are expected to increase by 1% over 2006 (actual sales volumes in 2006 were 97.48 bcm). Major increases are expected in certain target markets in the Rest of Europe, mainly in the Iberian Peninsula, the North of Europe, France and Germany/Austria markets;
- Sales volumes of electricity are expected to slightly increase from 2006 (actual volumes in 2006 were 31.03 TWh);
- Refining throughputs on Eni’s account are forecast to slightly decrease from 2006 (actual throughputs in 2006 were 38.04 mmtonnes) due to expiration of a processing contract at the Priolo refinery owned by a third party late in 2006, to be offset by higher throughputs expected at the Gela, Livorno and Taranto refineries;
- Retail sales of refined products are expected to slightly increase from 2006 (actual volumes sold in 2006 were 12.48 mmtonnes). Increases are expected on both the Italian and European markets due to the entry into service of new outlets, and also following the acquisition of stations in target markets.
In 2007 management expects Eni’s capital expenditure on exploration and capital projects to amount to approximately euro 10.5 billion, representing a 34% increase over 2006. Approximately 86% of this capital expenditure programme is expected to be deployed in the Exploration & Production, Gas & Power and Refining & Marketing divisions. Furthermore, acquisitions of assets and interests amounting to euro 9.2 billion are forecast for 2007, mainly related to: (i) the agreed purchase of ex-Yukos assets; (ii) the other agreements which are expected to be finalised by the end of the year, including the purchase of upstream assets in the Gulf of Mexico and Congo, and a retail station network in the Central-Eastern Europe. Assuming Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni, net cash outflows used in investing activities will decrease to euro 16.2 billion.
On the basis of the expected cash outflows for this capital expenditure and acquisition programme, and shareholders remuneration, also assuming a 55$/barrel scenario for the Brent crude oil, Eni foresees its leverage to range from 0.3 to 0.4 by the end of the year, depending on the exercise of the above mentioned call options by Gazprom.

##### Table of Contents

Bottom line
Eni’s net profit for the first quarter of 2007 was euro 2,588 million, down euro 386 million from the first quarter of 2006, or 13%, due primarily to a lower operating performance (down euro 490 million, or 8.8%) as a result of a decline in the Exploration & Production division, partially offset by a positive performance delivered by Eni's downstream and the Engineering & Construction businesses. This reduction in net profit was also due to higher net financial expenses mainly owing to losses on the fair value evaluation of certain financial derivative instruments.
Eni’s adjusted net profit amounted to euro 2,680 million, down 9.3% from the first quarter 2006. Adjusted net profit is arrived at by excluding an inventory holding loss of euro 97 million and special income of euro 5 million net.
Divisional performance
The decline in the Group adjusted net profit was owed to the reduction of adjusted net profit registered in the Exploration & Production division (down euro 686 million or 32.7%), due to a weaker operating performance (down euro 1,119 million or 26.3%) which was adversely impacted by the appreciation of the euro over the dollar (9.0%), a decline in production sold (down 9.5 mmboe/d), lower oil realizations in dollars (oil down 3.3%), and higher exploration expenses.
The decline in the adjusted net profit of the Exploration & Production division was partly offset by a higher adjusted net profit reported in the divisions:

- Gas & Power (up euro 280 million or 31.9%), as a result of an improved operating performance (up euro 480 million or 40%) reflecting higher natural gas selling margins supported by a favourable trading environment relating particularly to trends in the euro vs. the dollar exchange rate. The division’s performance also benefited from positive developments in Italy’s regulatory framework. These positives were partly offset by lower natural gas sales (down 2.87 bcm or 10.4%), impacted by lower European gas demand due to the unusually mild weather conditions registered in the first quarter 2007;

- Refining & Marketing (up euro 27 million or 31.4%), reflecting an improved refining performance boosted by higher processed volumes and better yields, also in light of lower maintenance shutdowns;

- Petrochemicals (up euro 63 million, or 393.8%), due to an improved operating performance (up euro 99 million) reflecting a recovery in product selling margins;

- Engineering & Construction (up euro 58 million, or 66.7%), reflecting an improved operating performance (up euro 98 million) against the backdrop of favourable demand trends in oilfield services.

Net borrowings and cash flow
Net borrowings as of March 31, 2007 amounted to euro 3,852 million, decreasing by euro 2,915 million from December 31, 2006. Net cash provided by operating activities totalled euro 5,563 million. Main cash outflows related to: (i) capital expenditure totalling euro 2,013 million; (ii) the repurchase of own shares for euro 203 million by Eni SpA and euro 242 million by Snam Rete Gas SpA.
Leverage, the ratio of net borrowings to shareholders’ equity including minority interest decreased to 0.09, from 0.16 at December 31, 2006.
Repurchase of own shares
From January 1 to March 31, 2007 a total of 8.52 million own shares were purchased by the company for a total amount of euro 203 million (representing an average cost of euro 23.847 per share). Since the inception of the share buy-back programme (September 1, 2000), Eni has repurchased 344 million shares, equal to 8.58% of outstanding capital stock, at a total cost of euro 5,716 million (representing an average cost of euro 16.638 per share).
Capital expenditure
Capital expenditure in the first quarter of 2007 amounted to euro 2,013 million (euro 1,340 million in the first quarter 2006) and related mainly to:

- Development activities (euro 909 million) deployed mainly in Kazakhstan, Egypt, Angola, Italy and Congo and exploration projects (euro 373 million) of which 91% was spent outside Italy, primarily in Norway, Nigeria, Egypt and the United States. In Italy exploration activity related primarily to projects off the coast of Sicily;

- upgrading of natural gas import pipelines to Italy and the development and maintenance of Eni’s natural gas transport network in Italy (for an overall amount of euro 144 million).

Post closing events
Upstream asset acquisition in the Gulf of Mexico
On April 30, 2007 Eni agreed to acquire the Gulf of Mexico upstream activity of Dominion, one of the major American energy companies listed on the New York stock exchange at the agreed price equal to US $4,757 million, inclusive of exploration assets for US $680 million.
The transaction, includes production, development and exploration assets located in deepwater Gulf of Mexico. The acquisition will increase Eni’s equity production in the Gulf of Mexico from the current 36,000 boepd to more than 110,000 boepd in the second half of 2007 and the proved and probable equity reserves by 222 million boe, at an implied cost per barrel of US $18.4. From 2007-2010 production from the acquired assets is expected to average more than 75,000 boepd.
In addition, Eni will further enhance its portfolio in the Gulf of Mexico thanks to new leases with significant exploration potential; approximately 60% of these leases are operated.
The transaction is subject to government approvals, 30-days notice to holders of certain preferential rights to purchase (which apply to less than 5% of total reserves), and to other customary precedent conditions. Final agreement is anticipated to take place on July 2, 2007.
Yukos asset acquisition
On April 4, 2007 Eni, through its partnership in EniNeftegaz (60% Eni, 40% Enel SpA) acquired Lot 2 in the Yukos liquidation procedure for a total price of $5.83 billion. Lot 2 includes:
• 100% of OAO Arctic Gas Co
• 100% of ZAO Urengoil Inc
• 100% of OAO Neftegaztechnologia.
These three companies own 5 oil and gas fields and condensate fields and parts of 3 others in the Yamal Nenets (YNAO) region, the world’s largest gas producing region. Together they have large oil and gas reserves.
Eni and Enel have offered Gazprom an option to acquire 51% participation interest in these assets within two years. In the event that Gazprom exercises its call option, the assets will be operated through a joint venture between Eni and Gazprom which will have access to Eni’s most advanced technologies.
Lot 2 also includes:
• various minor assets that will be sold or liquidated and
• 20% of OAO Gazprom Neft which will be wholly owned by Eni.
Eni offered Gazprom an option to acquire 20% participation interest in OAO Gazprom Neft within two years, at a total price of $3.7 billion, in addition to financial expenses relating to the acquisition. These agreements are an additional step in implementing the Strategic Partnership between Eni and Gazprom signed in November 2006, under which the two companies established an alliance to develop upstream, midstream and downstream energy projects inside and outside of Russia.
Acquisition of the retail station network in Czechia, Slovakia and Hungary
On April 27, 2007 Eni and ExxonMobil Central Europe Holding GmbH signed an agreement for the sale of shares of Esso spol sro (Esso Czechia), Esso Slovensko spol sro (Esso Slovakia) and ExxonMobil Hungary Kft to Eni. The agreement, subject to the approval by relevant authorities, includes ExxonMobil's retail station network in the three countries, totalling 102 stations and its aviation business at the Prague and Bratislava airports.

Acquisition of 70%, including operatorship, of the Nikaitchuq Field in Alaska
On April 11, 2007 Eni acquired 70% and the operatorship of the Nikaitchuq Field, located on and offshore in the North Slope of Alaska. Eni, which already owned a 30% stake in the field, now retains the 100% working interest. Eni acquired the additional interest and operatorship as the result of an agreement with Kerr-McGee Oil and Gas Corporation, a wholly owned subsidiary of Anadarko Petroleum Corporation.
Nikaitchuq would be the first development project operated by Eni in Alaska. Successful appraisal drilling has been completed, confirming the potential viability of the development project. Plans for a phased development are currently being evaluated with the target of sanctioning the project by year end, and first oil to flow by the end of 2009. The Nikaitchuq project comprises the drilling of approximately 80 wells, out of which 32 are located onshore and the remaining from an offshore artificial island. All wells will then be tied back to a production facility located at Oliktok Point to reach a production of 40,000 b/d. Total investment will amount to approximately $900 million.
Memorandum of Understanding for the acquisition of an interest in Angola LNG Ltd
On April 2, 2007 Eni and Sonangol signed a Memorandum of Understanding for the acquisition of a 13.6% stake in Angola LNG Limited Consortium (A-LNG). This company is responsible for the construction of an LNG plant in Soyo, 300 km north Luanda, with a yearly capacity of 5 million tonnes.
Upon completion of this agreement, Angola LNG Limited’s shareholding structure will be as follows: Sonangol 22.8%, Chevron 36.4%, Eni 13.6%, Total 13.6% and BP 13.6%.
The project, for a total investment of approximately $4 billion, has been approved by the Angolan Government and Parliament. It envisages, for 28 years, the development of 220 billion cubic meters of gas, the production of 128 million tons of LNG, 104 million barrels of condensate and 257 million barrels of LPG.
LNG will be directed to the United States market and will be delivered to the re-gasification plant of Pascagoula, in the Gulf of Mexico, in which Eni, following this agreement, will acquire re-gasification capacity of 5 billion cubic meters per year.
Other information
The Board also approved the merger into the parent company of Eni’s wholly-owned subsidiaries AgipFuel, Napoletana Gas Clienti and Siciliana Gas. The relevant merger proposals were approved by the Board on March 29, 2007.
Financial and operating information by division for the first quarter 2007 is provided in the following pages.

Adjusted operating profit for the first quarter 2007 was euro 3,132 million, a decrease of euro 1,119 million from the first quarter 2006, or 26.3%), due primarily to:

- An adverse impact of approximately euro 300 million resulting from the appreciation of the euro versus the dollar.

- A lower production sold, which was down 9.5 mmboe.

- Lower oil realisations in dollars (down 3.3%), partly offset by slightly higher gas prices (up 1.3%).

- Higher expenses incurred in connection with exploratory activity (euro 188 million; euro 218 on a constant exchange rate basis).

- Higher production costs and amortisation/depreciation charges which also reflects the impacts of sector-specific inflation.

The adjusted net profit was euro 1,409 million, down euro 686 million from the first quarter of 2006. This result was impacted by a weaker operating performance and a higher tax rate (increased from 50.6% to 54.7%), primarily due to the Algerian windfall tax on upstream earnings effective August 1, 2006 and the supplemental tax rate applicable to profit earned in North Sea operations as enacted by the British Government in July 2006.

##### Table of Contents

Oil and natural gas production in the first quarter of 2007 averaged 1,734 kboe/d, a decrease of 93 kboe/d from the same period of the previous year (down 5.1%). This reduction was due primarily to the unilateral cancellation of the Dación field service contract by the Venezuelan state company PDVSA with effect from April 1, 2006 (down 60 kboe/d) and social unrest in Nigeria. Factoring in these effects, oil and natural gas production level was in line with the first quarter 2006. Production increases were achieved mainly in Libya, Kazakhstan and the Gulf of Mexico offsetting mature field declines in Italy and facility shutdowns.
Daily production of oil and condensates (1,030 kbbl) decreased by 113 kbbl, or 9.9% from the first quarter of 2006. Production decreases were reported mainly in Venezuela and Nigeria due to the above mentioned causes and in the United Kingdom due to a technical problem in the Elgin/Franklin field (Eni's interest 21.87%) and ordinary maintenance shutdowns at other facilities. In Italy a few technical problems occurred at the FPSO operating the Aquila field. Significant increases were registered in Kazakhstan, and the United States.
Daily production of natural gas for the first quarter (4,061 mmcf/d) increased by 141 mmcf/d, or 3.6%, mainly as a result of the build-up of the Bahr Essalam field offshore Libya, full operations at train fifth at Bonny LNG plant in Nigera, a better performance of Norway’s largest fields, and full production of Bayu Undan gas field offshore Australia. Gas production in Italy decreased due to mature field declines.

The adjusted operating profit of the Gas & Power division totalled euro 1,683 million, up euro 480 million or 39.9% from the first quarter of 2006, reflecting primarily:

- Increased natural gas selling margins owing to a favourable trading environment relating particularly to trends in the euro vs. the dollar exchange rate.

- 11 -

##### Table of Contents

- A favourable evolution of the regulatory framework in Italy. This reflected the enactment of Resolution No. 79/2007 by the Authority for electricity and Gas implementing a new setup of the indexation mechanism of the raw material cost component in supplies to residential and commercial users related to the period from January 1, 2005 to June 30, 2006. Following this, Eni has partially or totally reversed provisions accrued in the accounts for 2005 and the first half of 20061.
- Higher purchase costs were incurred in the first quarter of 2006 as a result of a climatic emergency during the 2005-2006 winter.

These positives were partly offset by a decline in natural gas sales (down 2.87 bcm, or 10.4%), a result of lower European gas demand because of the unusually mild weather conditions of the first quarter 2007, partly offset by a growth in sales in certain target markets in the rest of Europe. Lower gas demand negatively affected the operating performance of transport activities in Italy and volumes distributed on low pressure networks. Sales volumes of electricity decreased by 0.12 TWh, or 1.6%.
Special charges for the quarter referred to redundancy incentives (euro 2 million).
The adjusted net profit was euro 1,159 million, up euro 280 million, or 31.9%, reflecting the increased adjusted operating profit.
Eni’s worldwide natural gas sales for the first quarter of 2007 amounted to 28.14 bcm, including own consumption and sales by affiliates and upstream sales in Europe, with a decrease of 3.06 bcm from the first quarter of 2006, or 9.8%. This decline was impacted by lower seasonal gas sales due to unusually mild winter time.
In an increasingly competitive market, sales in the Italian market were 15.41 bcm with a decrease of 2.06 bcm, or 11.8%. All market segments posted sale volumes declines from the first quarter of 2006:

- Sales to residential users were down by 0.71 bcm.
- Sales to industrial users were down by 0.47 bcm.
- Sales to wholesaler users were down by 0.44 bcm.
- Sales to thermoelectric users were down by 0.34 bcm.

Gas sales in the Rest of Europe were 7.9 bcm with a decrease of 0.67 bcm, or 7.8%, due to:

- Lower sales under long-term supply contracts to Italian importers (down 0.75 bcm), despite the full production of natural gas from the Libyan fields.
- Lower sales in the Hungarian market (down 0.49 bcm).

These decreases were partly offset by increases in the supplies to the Turkish (up 0.34 bcm) and Spanish (up 0.18 bcm) markets.

The Refining & Marketing division reported an adjusted operating profit of euro 120 million, representing an increase of euro 31 million from the first quarter of 2006, or 34.8%. This increase reflected primarily a better operating performance delivered by the refining activity, which was boosted by higher processed volumes and better yields also in light of lower maintenance shutdowns. The benefit of higher refining margins (margins on the Brent crude oil were up 0.11 dollar/bbl, or 3.7%) was more than offset by thenegative impact of the

euro appreciation over the dollar. Marketing activities in Italy reported a lower operating profit due mainly to lower retail margins and a decline in wholesale volumes as a consequence of lower heating oil demand in Italy particularly in the thermoelectric sector caused by a relatively mild winter weather.
The adjusted net profit was euro 113 million, up euro 27 million, or 31.4%, due to the improved operating performance.
Special charges excluded from the adjusted operating profit for the first quarter 2007 were euro 18 million, reflecting environmental provisions and provisions for redundancy incentives.
Refining throughputs on Eni’s own account increased by 390 ktonnes from the first quarter of 2006, to 9 mmtonnes, or 4.5%. This increase was due to lower maintenance shutdowns in Livorno and Venice refineries, partly offset by expiration of a processing contract at the Priolo refinery owned by a third party and lower throughputs at the Gela and Taranto refineries due to planned maintenance shutdowns.
The wholly-owned refineries throughputs increased by 0.81 mmtonnes from the first quarter of 2006, to 6.67 mmtonnes, or 13.8%, mainly in the Livorno, Taranto and Venice refineries. The wholly-owned refinery utilisation rate was 100% based on the utilisation rates of refinery balanced capacity.
Sales of refined products increased by 20 ktonnes from the first quarter of 2006, to 12.34 mmtonnes, or 0.2%, due to: (i) higher volumes sold to oil companies and traders in Italy, partly offset by lower volumes sold to the petrochemical sector reflecting expiration of a processing contract at the Priolo refinery (overall up 350 ktonnes); and (ii) higher sales on both the retail and wholesale markets in the Rest of Europe (up 50 ktonnes). These positives were partly offset by a decline in both the retail and wholesale markets in Italy (down 410 ktonnes) due to the impact of milder weather in the first quarter 2007 and competitive pressure.
Sales of refined products on the retail market in Italy decreased by 80 ktonnes from the first quarter of 2006, to 1.98 mmtonnes, or 3.9%, primarily due to competitive pressure and lower demand.
Sales in the retail market in the Rest of Europe increased by 30 ktonnes from the first quarter of 2006, to 0.9 mmtonnes, or 3.4%, mainly in Spain.
Sales in the wholesale market in Italy decreased by 330 ktonnes from the first quarter of 2006, to 2.61 mmtonnes, or 11.2%, due to lower demand for heating products particularly from the thermoelectric sector caused by unusually milder weather.
Sales on the wholesale market in the Rest of Europe increased by 20 ktonnes, to 1.05 mmtonnes, or 1.9%, primarily reflecting the increase in sales in the Czech Republic.

NON-GAAP Measures
Reconciliation of reported operating profit and net profit to results on an adjusted basis

Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Further, finance charges on finance debt, interest income, charges or income deriving from the fair value evaluation of derivative financial instruments held for trading purposes, and exchange rate differences are excluded when determining adjusted net profit of each business segment.
The taxation effect of such items excluded from adjusted net profit is determined based on the specific rate of taxes applicable to each item, with the exception for finance charges or income, to which the Italian statutory tax rate of 33% is applied.
Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them in order to facilitate a comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment.
The following is a description of items which are excluded from the calculation of adjusted results.
Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting.
Special items include certain relevant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non recurring material income or charges are to be clearly reported in the management’s discussion and financial tables.
Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition gains or losses on the fair value evaluation of derivative financial instruments held for trading purposes and exchange rate differences are excluded from the adjusted net profit of business segments.
Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charge pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production division).
Finance charges or interest income and related taxation effects excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies.
For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and reported net profit see tables below.

Summarized Group balance sheet (a)
Summarized group balance sheet aggregates the amount of assets and liabilities derived from the statutory balance sheet in accordance with functional criteria which consider the enterprise conventionally divided into the three fundamental areas focusing on resource investments, operations and financing. Management believes that this Summarized group balance sheet is useful information in assisting investors to assess Eni’s capital structure and to analyse its sources of funds and investments in fixed assets and working capital. Management uses the Summarized group balance sheet to calculate key ratios such as return on capital employed (ROACE) and the proportion of net borrowings to shareholders’ equity (leverage) intended to evaluate whether Eni’s financing structure is sound and well-balanced.

Other current liabilities net increased by euro 589 million compared with December 31, 2006. This increase was due to a euro 575 million loss recognized on the fair value evaluation of certain financial derivatives instruments. The Group entered into such transactions in order to hedge cash flow expected in the 2008-2011 period from the sale of approximately 2% of Eni’s proved hydrocarbon reserves as of 2006 year-end in connection with its purchase of certain oil producing assets and proved and unproved property onshore Congo and in the Gulf of Mexico finalized in February and April 2007, respectively. In light of this, Eni put in place certain forward sale contracts at a fixed price and call and put options with the same date of exercise. These options can be exercised in presence of crude oil market prices higher or lower compared with contractual prices. Gain and losses relating to these cash flow hedges are taken to reserves. This treatment does not apply to the time value component arising from market price fluctuations within the range provided by these call and put options which is recognized in the profit and loss account under the item net financial expenses because the hedging relationship is ineffective.

Leverage and net borrowings
Leverage is a measure of a company’s level of indebtedness, calculated as the ratio between net borrowings which is calculated by excluding cash and cash equivalents and certain very liquid assets from financial debt and shareholders’ equity, including minority interests. Management makes use of leverage in order to assess the soundness and efficiency of the Group balance sheet in terms of optimal mix between net borrowings and net equity, and to carry out benchmark analysis with industry standards. In the medium term, management plans to maintain a strong financial structure targeting a level of leverage up to 0.40.

ROACE (Return On Average Capital Employed)
Return on Average Capital Employed for the Group, on an adjusted basis is the return on Group average capital invested, calculated as the ratio between net adjusted profit before minority interests, plus net finance charges on net borrowings, less the related tax effect and net average capital employed. The tax rate applied on finance charges is the Italian statutory tax rate of 33%. The capital invested as of period-end used for the calculation of net average capital invested is obtained by deducting inventory gains or losses as of the period, rectified from the related tax effect.
ROACE by business segment is determined as the ratio between adjusted net profit and net average capital invested pertaining to each business segment and rectifying the net capital invested as of period-end, from net inventory gains or losses (after applying the business segment specific tax rate).

Summarized Group cash flow statement
Eni’s summarized group cash flow statement derives from the statutory statement of cash flows. It allows to create a link between changes in cash and cash equivalents (deriving from the statutory cash flows statement) occurring from the beginning of period to the end of period and changes in net borrowings (deriving from the summarised cash flow statement) occurring from the beginning of period to the end of period. The measure enabling to make such a link is represented by “free cash flow” which is the cash in excess of capital expenditure needs. Starting from free cash flow it is possible to determine either: (i) changes in cash and cash equivalents for the period by adding/deducting cash flows relating to financing debts/receivables (issuance/repayment of debt and receivables related to financing activities), shareholders’ equity (dividends paid, net repurchase of own shares, capital issuance) and the effect of changes in consolidation and of exchange differences; (ii) changes in net borrowings for the period by adding/deducting cash flows relating to shareholders’ equity and the effect of changes in consolidation and of exchange differences.

San Donato Milanese (Milan), May 28, 2007 - Inquiry by the Public Prosecutor Office of Milan, Paolo Scaroni, Eni’s CEO commented:

"We are confident: the measurements under investigation receive a special attention from all the companies operating in the gas market in Italy and abroad. In fact, I myself, as soon as I arrived in Eni, gave mandate to specialized international consultants to undertake an assessment of this gas measurements procedures.

Furthermore, we are referring to measurements on non-booked gas, which is the difference between gas that Eni buys from its suppliers and the one that Eni then sells to distributors. This difference represents so far, for our company, a net loss of some hundred million cubic meters of gas per year. It’s important for me to remind that gas measurements for the retail market are carried out in strict compliance with the indications given by the Authority for Energy and Gas and by the competent offices of the Ministry of Economic Development".

Eni completes acquisition of Maurel & Prom’s assets in Congo

San Donato Milanese (Milan), May 30, 2007 - Eni announces that it has today completed the acquisition of Maurel & Prom assets in the Republic of Congo. Eni has obtained the operatorship of the M’Boundi (Eni equity 43.1%) and Kouakouala "A" (66.67%) concessions and of the Le Kouilou exploration permit (48%).

Through the development of the M’Boundi field, which has oil-in-place estimated at 1.4 billion barrels and 2P reserves amounting to 320 million barrels, Eni’s equity production in Congo will rise from 67,000 barrels per day (bpd) in 2006 to approximately 100,000 bpd in 2010.

In the development of these new fields, Eni intends to create important synergies with existing activities in the country. By adopting the most advanced technologies, such as an intense drilling programme of water injection wells, Eni also aims to improve the oil recovery factor of the acquired fields and to develop the exploration potential of Le Kouilou permit.

As part of its sustainability strategy, Eni has also signed a "Protocole d’Accord" with the Republic of Congo for doubling the volumes of power of the Djeno power station by installing a second 25-MW turbo-generator to be supplied with associated gas produced from the M’Boundi field. This project aims at increasing the power and reliability of the local electricity system, needed for the country’s industrial development and social improvement.

Eni’s strategy is consistent with these goals, and relies upon the following guidelines: leverage on its asset portfolio and execution capabilities; allocate the cash generated from operations to capital expenditure to drive long-term organic growth and to an attractive and sustainable flow of dividends; use cash in excess of capital expenditure and dividend needs to continue the programme of share repurchase and to maintain a solid financial structure;

apply a tight financial discipline to investment decisions; accomplish continued operating efficiency and effectiveness; manage risks; devote significant resources to technological innovation in order to create and maintain competitive advantages; promote the sustainability of the business model. Over the next four years, Eni expects to invest approximately euro 44.6 billion in its businesses to support continued growth also beyond 2010, featuring the largest investment program in Eni history. The significant amount of cash flow generated from operations will enable Eni to finance its capital expenditure programme and to distribute shareholders an attractive and sustainable flow of dividends. Excess cash will be allocated to continuing share repurchase and to maintain a sound balance sheet. In particular, management expects that Eni’s free cash flow1 will allow to sustain the current flow of dividends in real terms, even with a scenario of 40 $/bbl Brent. BUSINESS STRATEGIES Exploration & Production In the Exploration & Production business, Eni intends to deliver strong oil and gas production growth, targeting a production level of 2 million boepd by 2010, corresponding to a compound average growth rate of 3% from 2007 to 2010. The growth options we are presently pursuing with our partner Gazprom may potentially accelerate the achievement of our growth targets. |  | Eni will maintain a strong focus on exploration activities. Investments are expected to be concentrated on well established areas of presence, where availability of production facilities and existing competencies will enable Eni to readily put in production discovered resources, capturing synergies. On the other hand, we expect to selectively pursue high risk/high reward opportunities arising from expansion in areas with high mineral potential. Leveraging on the access to new reserves and on the mineral potential of core assets, Eni expects to fully replace produced reserves trough organic additions. We will continue our commitment in expanding the LNG business in a global scale in order to monetize our large gas reserve base. This will be achieved by implementing significant capital expenditure in order to develop new gas reserves to ensure supplies to liquefaction plants and to build new liquefaction capacity. Gas & Power Our key objective in the Gas & Power division is to deliver a level of free cash flow of euro 2.1 billion in 2010, with an average growth rate of approximately 3%. This target will be achieved by implementing our strategy focused on growing our market share in key European markets, preserving our domestic natural gas business, effectively managing regulated business and the power generation business, and expanding LNG sales. In strengthening our market leadership in Europe, we will leverage on our competitive advantages ensured by gas availability – both equity and purchased under long term supply contracts – access to infrastructure, an adequate regasification capacity, long-standing relationships with natural gas producing countries, a large customer base, and market knowledge.

The target of maintaining sales volumes on the domestic market will be achieved thanks to the support of an effective commercial policy, enhanced by the expected launch of the dual offer of gas and electricity. By 2010 Eni will be selling some 105 bcm worldwide, with international sales expected to grow by a solid 10% per year on average. Refining & Marketing Eni’s key objective is to significantly increase profitability in the Refining & Marketing business. In pursuing this, Eni intends to enhance its refining activity by means of a huge investment program aiming at capturing market opportunities in terms of demand trends, also in connection with adoption of increasingly strict environmental requirements, and relative abundance of heavy and non-conventional crude. Planned actions are intended to boost refinery conversion rate and flexibility in order to produce higher-value products and to process low-quality crude that is typically discounted in the market-place, and to lower operating costs. In Marketing, we aim to extract full value from our retail business in Italy through a selective investment program, customer-focused marketing initiatives, effective differentiation of pricing, an improved premium-products offer, and operating efficiencies. We plan to selectively develop our presence outside Italy, aiming at strengthening our competitive position in target European markets, leveraging on |  | synergies deriving from the proximity to Eni’s production and logistic facilities. Engineering & Construction Saipem aims at capturing opportunities arising from a growing market, acquiring large projects in complex areas and supporting Eni’s investment plans. In order to achieve this, Saipem will leverage on its strong competitive position, enhanced by integration with Snamprogetti, and an important investment program intended to further expand the geographical reach and operational features of its world-class fleet. Technological innovation Our commitment in technological research and innovation underscores a fundamental belief that technology is key to acquiring and preserving competitive advantages over the long term and promoting sustainable growth. Over the next four years, we plan to invest approximately euro 1.5 billion to support these activities. The main lines of research under development pertain primarily to reduce costs to find and recover hydrocarbons, upgrade heavy oils, monetize stranded gas and protect the environment. In particular we are moving forward on our breakthrough technologies: EST (Eni Slurry Technology) for the full exploitation of the heavy barrel, TAP (gas transportation at high pressure) and GTL (gas-to-liquids) for gas monetization.

STRATEGIES
In Exploration & Production, Eni boasts strong positions in some of the fastest growing oil and gas basins in the world such as the Caspian Region, North and West Africa. The quality of our assets, long-standing relationships with key host countries, and a strong pipeline of capital projects and investment opportunities will enable Eni to deliver industry-leading growth in both the short and the long term. Consistent with this goal, strategies for our global exploration, development and production operations have remained basically unchanged for many years to date and feature as follows:

- Maintain strong production growth;

- Ensure medium to long-term business sustainability by focusing on reserve replacement;

- Develop new projects to fuel future growth; and

- Develop the LNG business.

In order to carry out these fundamental strategies, Eni intends to invest approximately euro 30.6 billion addressed to exploration initiatives and reserve development over the next four-year period.

2006 Highlights In February 2007, Eni purchased exploration and production onshore activities operated by Maurel & Prom in Congo, entailing a cash consideration of $1.4 billion. This deal is consistent with Eni’s strategy of purchasing proved and unproved reserves and producing assets in legacy countries where Eni can achieve synergies leveraging on own competencies and the availability of facilities. This transaction is subject to approval by the Congolese Authorities. In 2006 adjusted net profit was euro 7,279 million, up euro 1,093 million from a year ago (+17.7%), reflecting a better operating profit as a result of higher oil and natural gas realizations in dollars combined with increased production volumes sold. These positives were offset in part by higher operating costs and a high adjusted tax rate. Return on average capital employed calculated on an adjusted basis was 37.5% in 2006, higher than in 2005 (32.4%). Oil and natural gas production for the year averaged 1.77 mmboe/d, up 1.9% from 2005. This included the loss of production at the Venezuelan Dación oilfield and lower entitlements in certain Production Sharing Agreements (PSAs) and buy-back contracts due to higher oil and gas prices. Eni delivered its 3% production growth rate based on a $55 per barrel scenario, as announced in the 2006 quarterly production outlook. |  | Net proved reserves at December 31, 2006 stood at 6.44 bboe (down 6% from December 31, 2005), representing 10 years of remaining production at the current rate. Organic proved additions, as calculated by applying a year-end Brent price of $58.925 per barrel, replaced 65% of production. Assuming Brent is constant at $40 per barrel when determining entitlements in PSAs, the three-year average proved reserve replacement ratio would be 106%. Eni invested euro 3.6 billion in the development of oil and natural gas reserves, in particular in Kazakhstan, Angola, Egypt and Italy. In exploration activities Eni invested euro 1.4 billion (up 106% compared with 2005) to support reserve replacement and the renewal of its portfolio. In 2006, Eni achieved several hydrocarbon discoveries, mainly in Indonesia, Egypt, Kazakhstan, Norway, Nigeria, the United Kingdom, the Gulf of Mexico, Italy, Angola and Congo. A total of 68 exploratory wells were completed (35.9 net to Eni), with a commercial rate of success of 43% (49% net to Eni). A further 26 wells were in progress as of the year-end. Eni’s exploration portfolio was strengthened through acquisition of assets in both core areas such as Angola, Alaska, Brazil, Congo, Egypt, Nigeria, Norway, Pakistan, the Gulf of Mexico and new countries/areas with high mineral potential such as Mali, Mozambique and East Timor. Gross acquired acreage extends for approximately 259,000 square kilometers (152,000 net to Eni, 99% operated).

ENI FACT BOOK / EXPLORATION & PRODUCTION - STRATEGIES

MAINTAIN STRONG PRODUCTION GROWTH Eni’s strategy is to build on its strong position in some of the world’s most attractive oil and gas basins to deliver industry leading production growth. We plan to accomplish this by applying the most cost-effective technologies and operations management systems to each and every asset to maximize the commercial recovery of hydrocarbons. Eni’s assets are well balanced between mature producing fields and fields that are at the early stages of their producing cycles with significant opportunities for growth. Mature areas include mainland and offshore Italy, the North Sea and certain basins in Egypt. Growing areas include Libya, offshore and onshore West Africa, the Caspian Sea and the Nile Delta. Eni expects contributions from the latter to boost production growth to 2010 and beyond. Eni continually invests in its existing asset base to increase resource recovery, maximize profitability, and extend field life. New production volumes are generated through workovers, drilling of new wells, and project implementation. In 2006, Eni invested euro 3.6 billion to develop new reserves and to maximize resource recovery from existing fields. In the next four years, Eni plans to invest approximately euro 322.5 billion evenly allocated to initiatives intended to counteract mature field decline, fuel medium-term growth and support growth beyond 2010. Several fields/projects were started up during 2006. Among the key start-ups are: (i) the Benguela/Belize and Lobito/Tomboco fields in Block 14 (Eni’s interest 20%) in Angola, holding recoverable reserves of approximately 460 mmbbl. Peak production at 158 kbbl/d (20 net to Eni) is expected in 2009 upon completion of the drilling program; (ii) the fifth train as a part of the development of the Bonny liquefaction plant (Eni’s interest 10.4%) in Nigeria, increasing plant capacity to 17 mmtonnes/y of LNG (812 bcf/y of feed gas); (iii) the gas phase of the Bayu-Undan field (Eni’s interest 12.04%) in Australia, starting supplies to the Darwin plant with liquefaction capacity of 3.5 mmtonnes/y of LNG. Peak production at 160 kboe/d (18 net to Eni) is expected in 2008. Production volumes outlook In 2006, oil and gas production averaged 1,770 kboe/d, up 33 kboe from 2005 or 1.9%, despite: (i) the impact of the loss of production at the Dación oil field in Venezuela (down 46 kboe/d) as a consequence of the unilateral cancellation of the relevant service contract by the Venezuelan state oil company PDVSA; and (ii) adverse entitlement effects (down 21 kboe/d) in PSAs and buyback |  | contracts due to higher oil prices. Production growth was driven by a remarkable increase in gas production mainly in Libya, Egypt, Nigeria, Australia and Croatia; oil production increased in Angola and Libya. Organic growth was partially offset by mature field declines and production outages in Nigeria due to social unrest. The share of production outside Italy was 87% (85% in 2005). In the medium term, Eni expects to deliver a 3% compound average growth rate from 2007 to 2010, targeting a production level in excess of 2 mmboe/d by 2010. In subsequent years and up to 2013, Eni projects an annual growth rate of 3%. This goal will be achieved entirely through organic growth mainly in our key producing basins of North and West Africa and the Caspian region, leveraging on Eni’s unique position and solid relationships with many of the fastest growing producing countries in the world and on its strong pipeline of capital projects and investment opportunities. In greater detail, production growth will be fed by means of: developing LNG projects, aiming at monetizing our large gas reserve base; starting up new fields, some of which already under execution and other waiting for finalization of exploratory and appraisal activities; leveraging on our long life fields, including Karachaganak in Kazakhstan, the Western Libyan Gas project, Val d’Agri in Italy, Ekofisk and Aasgard offshore Norway, Belayim and Port Fouad in Egypt, and, in perspective, our massive Kashagan field; optimizing reserve recovery from declining fields. Eni’s future production profiles are based on a long-term Brent price assumption of 40 $/bbl in real terms. ENSURE MEDIUM TO LONG-TERM BUSINESS SUSTAINABILITY BY FOCUSING ON RESERVE REPLACEMENT Eni intends to pay special attention to reserve replacement in order to ensure the medium to long term sustainability of its business. In pursuing this goal, Eni intends to: optimize its portfolio of development properties by focusing on core areas, seeking new opportunities and divesting marginal assets; pursue new exploration opportunities targeting a sound balance between high risk/high reward initiatives and established/mature projects. As of December 31, 2006, Eni’s portfolio of mineral rights consisted of 1,029 exclusive or shared rights for exploration and development in 36 countries on five continents for a total net acreage of 385,219 square kilometers. Of these, 48,273 square kilometers concerned production and development.

This geographically and geologically diverse, high-quality portfolio balances risks and rewards to deliver both near-term and long-term production growth. In the medium term, Eni expects to more than replace produced reserves through organic additions. Eni’s reserve replacement ratio will be supported by the high mineral potential of our assets located in core areas such as the Caspian Sea, West and North Africa. The success of Eni’s approach is demonstrated by its ability in replacing produced reserves. In the 2003-2006 four-year period, exploration reserves discovered were approximately 700 mmboe on average for a cumulative amount of 2.8 bboe, higher than our cumulative production over the same period frame. Positive contributions came from both legacy countries such as Nigeria, Angola, Egypt and Kazakhstan and new frontier areas such as the Barents Sea and the ultra-deep waters of the Gulf of Mexico. At 25 bboe, our solid resource base1 will secure 38 years of production at current rates. Under SEC reporting standards, proved reserves at 2006 year-end were 6.4 billion boe, representing a life index of 10 years. In the 2004-2006 period, considering adverse entitlement impacts in certain PSAs and buy-back contracts resulting from higher oil prices and assuming Brent constant at $40 per barrel when determining entitlements in PSAs, we would have replaced on average 106% of production through organic additions. For 2006 only, by applying the year-end price of $58.925/bbl, organic additions for the year came in at 417 mmboe with a reserve replacement ratio of 65%. Exploration activities will play a crucial role in enlarging Eni’s resource base in order to fuel new production, and in securing access to new opportunities. In light of this, management will devote a great deal of focus and effort to exploration. In 2006, Eni more than doubled its investment in exploration from the previous year, resulting in a total of 68 wells drilled with an SEC exploration success of 43%, and capturing 12 new opportunities spanning from new, untested exploration plays to well established plays or already-discovered resources, for a total acreage of about 152,000 square kilometers net to Eni, of these 99% as operator. In the next four years, management plans to invest on average approximately euro 31.1 billion per year in exploration activities, resulting in a cumulative euro 34.4 billion that is substantially higher (+51%) than the previous four-year |  | plan (2006-2009). The cornerstones of Eni’s exploration strategy are: selectively assess opportunities to enhance the competitiveness of Eni’s full-cycle production costs; concentrate resources in core areas: approximately 70% of planned investment will be directed to 10 countries; exploit the full mineral potential of recently acquired areas; complete portfolio renewal. In fact, management intends to concentrate investments in well established areas of presence where availability of production facilities, existing competencies and log-term relationships with host countries will enable Eni to readily put in production discovered resources, reducing the time to market and capturing synergies. On the other hand, Eni expects to selectively pursue high risk/high reward opportunities arising from expansion in areas with high mineral potential. Finally, portfolio renewal will be completed, bearing in mind that approximately 70% of total acreage has been renewed over the last three years. DEVELOP IN LNG BUSINESS Eni operates its gas business as an integrated portfolio in order to fully extract value from the gas chain and to monetize its large gas reserves. Liquefied Natural Gas is a key part of this strategy. Eni intends to build a global LNG business, aiming at: exploiting gas equity availability in order to supply the attractive markets of Europe and North America; growing LNG production in areas with high potential and low producing costs; purchasing interests in liquefaction plants in order to support the development of the LNG business. Net liquefaction capacity in 2006 was 321 bcf, mainly concentrated in Nigeria and Egypt, and is expected to expand to 343 bcf in 2010 and in excess of 509 bcf in 2012 by means of developing capacity at the Bonny liquefaction plant, building the new Brass plant in Nigeria, and implementing the expansion plan of the Damietta LNG plant in Egypt.LNG sales are expected to grow from127 bcf in 2006 to166 bcf in 2010; equity gas supplies to LNG plants of 162 bcf in 2006 are expected to increase up to 233 bcf in 2010.

Exploration activity yielded positive results with the Aghar SW-1X oil discovery in the West Razzak concession, the Lotus North 1-X and Nada Ne 1-X oil wells in the Melehis concession. The latter two wells have started production. THE LNG BUSINESS IN EGYPT Eni owns a 40% interest in the Damietta natural gas liquefaction plant. As part of the expansion plan of the plant, Eni and its partners signed a framework agreement in June 2006 for doubling the capacity of the plant by means of the construction of a second train with a treatment capacity of 5 mmtonnes/y of LNG corresponding to approximately 268 bcf/y of gas for a twenty-year period starting in 2010. Eni will supply 88 bcf/y to the second train from new gas discoveries in the Nile Delta, some of which in the deep waters. A new company is going to be established for the construction of the plant made up of Eni, Unión Fenosa, SEGAS (Spanish Egyptian Gas Co), BP and Egyptian national companies EGAS and EGPC. Eni already supplies approximately 53 bcf/y to the first train of the plant for a twenty year period. Libya Eni started operations in Libya in 1959. In 2006 Eni’s oil and gas production averaged 222 kboe/d, the portion of liquids being 65%. Production activity is carried out in the Mediterranean offshore facing Tripoli and in the Libyan desert area, over a total acreage of approximately 39,569 square kilometers (34,113 net to Eni). The main production blocks in which Eni holds interests are: (i) onshore NC169A (Eni’s interest 50%) and offshore NC41 (Eni’s interest 30% for oil and 50% for gas); (ii) onshore NC 174 (Eni’s interest 33.3%) and (iii) onshore concessions 82 and 100 (Eni’s interest 50%). Eni also holds a 50% interest in the NC118 block where, after a declaration of commercial discovery, it is developing the A-NC118 field. In the exploration phase, Eni is operator of four onshore blocks in the Muzurk basin (161/1, 161/2&4, 176/3) an in the Kufra area (186/1, 2, 3 & 4). Exploration and production activities in Libya are regulated by concessions and PSAs. Eni’ s production in Libya is expected to post an increase in the medium term owing to |  | the expected ramp up of new structures near the Western Libyan Gas Project fields, despite mature field production declines. Libya confirms to be one of Eni’s largest oil and gas producing countries BLOCKS NC169/NC41 Production Block NC169 is located in the western Libyan desert near the border with Algeria while block NC-41 is located in the Mediterranean offshore north of Tripoli. Production comes from: (i) the onshore Wafa field started up in September 2004, which in 2006 produced 139 kboe/d of liquids and natural gas (69 net to Eni); (ii) the Bahr Essalam offshore field started up in August 2005, that in 2006 produced 102 kboe/d of liquids and natural gas (51 net to Eni); (iii) the Bouri offshore field (Eni’s interest 30%) discovered in 1976, that in 2006 produced 55 kboe/d of liquids (17 net to Eni). The Wafa and Bahr Essalam fields, containing recoverable reserves of approximately 1.6 bboe were developed as part of the upstream-midstream integrated Western Libyan Gas Project aimed also at exporting natural gas to Europe through the underwater Greenstream pipeline. In 2006 volumes delivered through this pipeline were 240 bcf and are expected to target 283 bcf (equal to approximately to an average of 777 mmcf/d) when operations are fully on line. Said volumes are supplied to third parties on the Italian natural gas market under long term contracts. Further 71 bcf of gas will be delivered to the Libyan market once these two fields have achieved production plateau. Production from these two fields is treated at the Mellitah plant on the Libyan coast, made up of three trains for the treatment of gas from Bahr Essalam, while the gas produced at Wafa is ready for sale. Mellitah includes also facilities for the compression of natural gas that is carried to Sicily, as well as facilities for the storage and loading of oil and LPG. In 2006 a total of 26 offshore producing wells were drilled and linked to the Sabratha platform as foreseen by phase 1 of the sanctioned project. The Bouri field is exploited through two platforms linked to an FPSO unit with a storage capacity of approximately 1.5 mmbbl. In 2006 the Bouri East Development project was completed with the start-up of 4 underwater wells.

The partners of OMLs 135 and 129 are also appraising the development of the Nnwa-Doro field and a possible marketing of the gas. In March 2007 Eni acquired a 48% interest and the operatorship of activities in OPL 135. The exploration program provides for the exploration and development of new oil and gas reserves near existing networks and the Kwake/Okpai power station operated by Eni over a period of 25 years. Exploration and production activities in Nigeria are regulated by Production Sharing Contracts. Eni’s counterparties are state owned oil companies, while in service contracts Eni acts as contractor for state owned companies. Service contracts provide for the recovery of reimbursable costs born by the contractor through a share of production, while non reimbursable costs (mainly costs related to dry wells) are recovered through the contractor’s share of profits.OPLs typically last 10 years. When a discovery is made OPLs are transformed into OMLs with a 20 year duration. Production is expected to increase in the medium term in particular for the exploiting of gas reserves that will enable Eni to reach approximately 200 kboe/d, confirming Nigeria among Eni’s largest producing countries. |  | OMLs 60, 61, 62 and 63 Blocks OML 60, 61, 62 and 63 accounted for 39% of Eni’s production in Nigeria in 2006. Liquid and gas production is supported by the LNG plant at Obiafu-Obrikom with a treatment capacity of approximately 706 mmcf/d and by the oil tanker terminal at Brass with a storage capacity of approximately 3 mmbbl. A large portion of the gas reserves of these four OMLs is destined to supply the Bonny liquefaction plant (see below). Another portion of gas production is employed in firing the combined cycle power plant at Kwale-Okpai with a 480 MW generation capacity which started operations in 2005. In 2006 supplies to this power station amounted 71 mmcf/d (approximately 12 kboe/d). This project is part of the Nigerian government and Eni’s plans for the reduction of carbon dioxide emissions in the atmosphere. In late 2006 this project was qualified as CDM (Clean Development Mechanism) by the United Nations as provided for by the Kyoto Protocol. The CDM at Opkai power station is the first approved in Nigeria. Exploration activities in these blocks remain intense.

These actions aim at increasing production from the present 50 kbbl/d to over 160 kbbl/d (14 net to Eni). In the medium term Eni’s liquid production in Iran is expected to increase due to ongoing development initiatives. Indonesia Eni has been present in Indonesia since 2000. Eni’s production in 2006 amounted to 23 kboe/d. Production is concentrated in the western offshore and onshore of Borneo and offshore Sumatra over a total acreage of 28,438 square kilometers (16,301 net to Eni). Exploration and production activities in Indonesia are regulated by PSA. Production Production consists mainly of gas and derives from the Sanga Sanga permit (Eni’s interest 37.81%). This gas is treated at the Bontang liquefaction plant, the largest in the world, and is exported to the Japanese, South Korean and Taiwanese markets. Activities are underway for mitigating the natural decline of production by means of infilling wells. Exploration Eni holds interest in 11 exploration blocks, 6 as operator with interests ranging from 20% to 100%. An intense exploration campaign is underway in the Tarakan basin offshore Borneo. Kazakhstan Eni has been present in Kazakhstan since 1992. Main activities are performed in the Karachaganak field onshore in western Kazakhstan and in the area covered by the North Caspian Sea PSA in the shallow waters of the Northern Caspian Sea. Eni is co-operator with British Gas with a 32.5% interest of the Karachaganak oil, gas and condensate field. In 2006 production from this field (net to Eni) averaged 64 kbbl/d of liquids and 6.4 mmcm/d of natural gas, totalling 103 kboe/d. This field is developed by producing liquids (oil and condensates) from the deeper layers of the reservoir and reinjecting the associated gas in the higher layers. This scheme enables to increase the recovery of liquids. Approximately two thirds of liquid production are stabilized at the Karachaganak Processing Complex (KPC) with a capacity of 150 kbbl/d and exported to Western markets, most of it through the Caspian Pipeline Consortium pipeline (Eni's interest 2%) linked to the field by a 635-kilometer long pipe, while the rest flows though the Atyrau-Samara pipeline from 2006. The remaining third of non stabilized liquid production and the associated gas not reinjected are marketed at the Russian terminal in Orenburg. Field activities in 2006 concerned: (i) the sanctioning of the |  | expansion of stabilization capacity (4th train) which will enable to further increase exported volumes entailing the achievement of better realization prices with respect to the sale on local Russian markets; (ii) the continuation of activities required for keeping production plateau at the current levels, in particular by drilling new wells. Studies are underway for designing a further development phase, as provided for in the PSA governing activities at this field, aimed at monetizing reserves of gas and associated liquids through the signing of gas sale contracts with Russian and Kazakh companies and the construction of a gas treatment plant. As part of the North Caspian Sea PSA, Eni with an 18.52% interest is single operator of the development of the Kashagan field, which is believed to be the most important discovery in the world in the past thirty years. The development plan sanctioned in February 2004 envisages field development through three phases aiming at producing from 7 to 9 bbbl of gross recoverable reserves, extendible to 13 bbbl through partial gas reinjection. The development plan of this field provides for the construction of production hubs located on platforms and artificial islands which will collect production from satellite islands from which production wells will be drilled. Oil and non reinjected gas will be treated in the hubs and delivered, through two separate lines, to onshore treatment plants (located at Bolashak, 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. The first development phase is progressing leveraging on the use of the most advanced techniques in order to cope with high pressures in the reservoir, the presence of high concentration of hydrogen sulphide and harsh environmental conditions. By the end of 2006, works had been completed corresponding to 59% of the initial scope, with the total amount of contracts awarded at $10.6 billion. Drilling activities and completion of development wells from the two artificial islands already installed have been progressing. In addition, three rigs, two of which being of the most advanced class, were installed on said islands. Three development wells were completed yielding high rates of productivity under test phase. Production start-up is currently scheduled for the third quarter of 2010 as compared to an initial forecast indicating a start-up in 2008, due also to the need on the part of Eni to perform certain studies to define measures intended to enhance the overall level

of safety and operability of facilities. As a result of said reconfiguration completed by year-end, the onshore design has been confirmed, while certain enhancements have been identified offshore which do not alter the original development concept. These enhancements are expected to be included in the development plan and implemented. Estimated capital expenditure to reach the 300 kbbl/d production target in first development phase stands currently at $19 billion. The cost increase over the approved budget of $10.3 billion in real terms 2007, was driven by: (i) the effect of exchange rates that caused a cost increase of materials and services in the oil industry; (ii) an underestimation of costs to conduct offshore operations in shallow/ultra shallow waters due to a lack of benchmarks, also reflecting technical and logistic issues and environmental constraints; (iii) the enhancements to the original layout of offshore facilities. Based on the high level of productivity yielded by the first three development wells, management currently |  | expects a full field production plateau of 1.5 mmbl/d, representing a 25% increase from the original target envisaged by the development plan. Capital expenditure amounts indicated above do not include 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. These include: (i) the use of existing infrastructure, such as the Caspian Pipeline Consortium pipeline (Eni's interest 2%) and the Atyrau-Samara pipeline; (ii) the laying of a new pipeline according to two different options. The first one envisages laying of a line connecting the Bolashak production centre with the Baku-Tbilisi-Cehyan pipeline (Eni's interest 5% corresponding to the right to transport up to 50 kbbl/y). The second option envisages laying of a pipeline designed to bypass the Turkish Straits of Bosporus and Dardanelles, enabling delivery of oil produced in the Caspian region to the Ceyhan commercial hub on the Mediterranean coast. Following award of the relevant license to the Turkish company Çalik Enerji, partnering Eni in this initiative (both with a 50% stake), engineering activities have been started in the second half of 2006. This new infrastructure is expected to be 550-kilometers long with a maximum transport capacity of 1 mmbbl/d of oil, expandable to 1.5 mmbbl/d. Evaluation activities of other discoveries made in the contractual area covered by the North Caspian Sea PSA made some good progress. A first appraisal well of the Kairan discovery was successfully drilled. Drilling of a second appraisal well of the Kalamkas discovery yielded productive results that emphasize the good productivity of the reservoir and a much larger extension of said discovery as compared to the initial estimate.

ENI FACT BOOK / GAS & POWER - HIGHLIGHTS

2006 Highlights In November 2006, Eni and Gazprom signed a broad strategic agreement. This agreement strengthens a long term partnership between the two companies and represents a fundamental step towards the security of energy supplies to Italy. Key features of this deal are the extension of the duration of Gazprom gas supply contracts to Eni until 2035, further strengthening Eni’s supply portfolio and the pursuing of joint initiatives in the upstream sector. Gazprom is expected to enter the Italian market by selling volumes of gas starting in 2007. Gazprom will obtain the availability of such volumes by means of a corresponding reduction in volumes previously supplied to Eni. The Gas & Power business confirmed its ability to generate strong and stable performances. The adjusted net profit rose euro 310 million to euro 2,862 million compared to 2005 (up 12.1%) reflecting primarily higher selling margins on natural gas sales in a favorable market scenario, a lower impact of Resolution No. 248/2004 of the Italian Authority for Electricity and Gas, a growth in natural gas volumes sold, volumes transported for the coming on line of the GreenStream gasline and electricity production sold. Return on average capital employed was 15.1% on an adjusted basis in 2006 (13.7% in 2005). |  | Capital expenditure totaled euro 1,174 million and related essentially to development and maintenance of Eni’s transport and distribution networks in Italy, the finalization of the upgrading plan of electricity generation capacity and the start up of the upgrading plan of import gaslines. Natural gas sales were up approximately 4% to 97.48 bcm primarily reflecting a growth in sales in a number of target European markets (up approximately 16% in particular in Turkey, Germany/Austria, France) also for the build-up of supplies of natural gas from Libya, partly offset by a decrease in sales in Italy due to mild weather conditions in the fourth quarter of the year. Electricity production sold was 24.82 terawatthour, up 9% from 2005, due to new generation capacity coming on stream. As a part of its development strategy of the natural gas distribution and sale businesses by means of regional alliances, Eni and its local authority partners defined the Toscana project with the establishment of a regional distribution company managed by Eni and boasting 1.6 million users and a regional selling company controlled by Eni boasting 600 k clients and 1.1 bcm of annual sales.

ENI FACT BOOK / GAS & POWER - THE GAS SYSTEM

THE GAS SYSTEM The gas supply, transport and marketing sector is experiencing far-reaching developments due to the increasing role of gas in satisfying global energy needs. Key reasons driving gas demand trends are: (i) continuing improvements in technologies applicable to all phases of the natural gas chain capable of reducing distances between production sites and consumption areas (LNG, GTL - gas to liquids, TAP - high pressure transport); (ii) the large amount of gas reserves; (iii) the higher environmental compatibility of natural gas as compared to other hydrocarbons in particular in the generation of electricity, along with expected increasingly tight regulations on emissions mainly due to the implementation of the Kyoto protocol; (iv) the increasingly wide adoption of the combined cycle as elective technology in power generation, based on lower investment costs, higher efficiency and lower emissions than other fuel based technologies; (v) economic, demographic and social development. In Europe (OECD) demand for gas is expected to grow by 40% by 2020 at an average annual rate of 2-3%, reflecting wider use of gas in power generation and new demand from the fastest growing countries. The relationship of developments and dynamics of demand and supply of natural gas forces operators in this business to adopt an international approach in planning flows of available supplies and uses, targeting long-term strategies in order to be able to adapt to the changes induced by the evolution of competition, for which an upgrading of infrastructure will prove crucial. A growing portion of European gas requirements is expected to be satisfied by imports via gasline, mainly from Russia, Algeria, Norway and Libya, taking account of the expected decline in European gas reserves. LNG will play an increasingly important role in satisfying European needs, with an expected 10% annual growth rate over the next four years. |  | The Italian natural gas market, third in size in Europe after the UK and Germany, is part of the structural change ongoing in Europe which will lead to the creation of a single energy market. In this context, Italy will be able to exploit is geographic location both as concerns the internal European market and the Mediterranean area. In 2006 gas consumption in Italy amounted to 84.4 bcm, down 2.2% from 2005; about 87% of gas requirements were met through imports and 13% was covered by domestic production. Eni expects natural gas consumption in Italy to increase with a compound average growth rate of about 2.5% over the next ten years, hitting approximately 106 bcm in 2015, mainly driven by an increased use in power generation, expected to outpace demand growth in other sectors, such as large industrial users, residential space heating in households and services, commercial and small businesses. Growing gas needs will be met by an increase in imported volumes, which will be supported by significant capital expenditure plans to build new or upgrade existing infrastructure, either under construction or announced.

ENI FACT BOOK / GAS & POWER - ACTIVITIES

Activities 1. Marketing and supply of gas Overview In 2006, Eni’s worldwide gas sales were 97.48 bcm (including upstream sales) up 3.27 bcm from 2005, or approximately 4%. In the medium term, Eni plans to increase worldwide sales targeting a volume of 105 bcm by 2010, corresponding to a 2.5% average growth rate over the 2007-2010 four-year period. To enhance its leadership on European markets, Eni will leverage on its strengths represented by gas availability both as equity gas and under long-term purchase contracts, operational flexibility ensured by the access to a wide-reaching transport network, regasification terminals and logistic assets, a large portfolio of clients and market knowledge. |  | 1.1 Marketing in Italy MARKET In 2006 Eni’s gas sales in Italy amounted to 57.09 bcm (including own consumption2), down 1.7% from 2005 due mainly to mild climate conditions in the fourth quarter of the year. This decline was partly offset by an increase in own consumption for power generation. The Italian market includes three groups of clients: industrial, residential and power generation users; they are further grouped as follows: (i) large industrial clients and power generation utilities directly linked to the national and the regional natural gas networks; (ii) the retail market which is composed of residential and commercial clients (households, commercial users, hospitals, schools, etc.), and small businesses located in urban centers supplied by wholesalers through low pressure distribution networks; and (iii) wholesalers, mainly local selling companies and distributors of natural

(2) |  | In accordance with Article 19, paragraph 4 of Legislative Decree No. 164/2000 the volumes of natural gas consumed in own operations by a company or its subsidiaries are excluded from the calculation of ceilings for sales to end customers and for volumes input into the Italian network to be sold in Italy.

gas for automotive use purchasing natural gas to sell it to final clients. At December 31, 2006, Eni boasts 6.54 million of clients, of which 6.10 million are retail customers. In the medium term, in an increasingly competitive market, Eni intends to maintain margins and sales volumes by leveraging on the expected growth of gas demand, maximizing the value of the gas chain focusing in particular on the most profitable clients, deploying a commercial offer tailored on client needs in terms |  | of pricing and quality of services, and boosted by the expected development of the combined offer of gas and electricity (“dual offer”). Eni targets sales volumes of at least 50 bcm in 2010. This target takes account of the expected increase in competitive pressure due to new supplies coming on the Italian gas market in view of the implementation of the upgrading plans of the import infrastructure to Italy, already underway or announced. In fact, import capacity is expected to increase by approximately 21 bcm by 2010, of these 13 bcm pertain to Eni’s ongoing upgrading program of its import infrastructure from Russia and Algeria (see “International transport activity”, below). Compliance with market limits imposed by Italian sector-specific regulation, in terms of both volumes intake into the national network and sales volumes, will be assured through the optimal allocation of Eni’s gas availability from supply contracts and equity production between sales in Italy and in the rest of Europe, and the use of gas in Eni’s power generation plants, leveraging also on the expected increase in demand.

A review of Eni’s presence in key European markets and commercial objectives at 2010 is presented below. |  |

France Eni sells natural gas to industrial clients and wholesalers. Eni is pursuing an aggressive marketing policy to gain market share, in particular in the segment of small businesses which presents good profitability and development perspectives. In the medium term, Eni expects to grow its current 1.1 bcm sales level at a 47% annual average growth rate, compared to an expected 3% average growth rate of market consumption, targeting volumes of approximately 5 bcm in 2010, equal to a 9% market share. Germany Eni is present on the German natural gas market through its affiliate GVS (Gasversorgung Süddeutschland GmbH - Eni 50%) which sold approximately 6.4 bcm in 2006, and with a direct commercial structure. In the medium term, Eni plans to significantly increase its sales to the business segment, leveraging on the pursuit of new opportunities arising from the ongoing liberalization process. The objective is to sell more than 7.5 bcm in 2010, equal to a 7% market share. IBERIAN PENINSULA Gas demand growth in the Iberian Peninsula is expected to outpace average European growth. Portugal Eni operates on the Portuguese market through its affiliate Galp Energia (Eni’s interest 33.34%) which |  | sold approximately 5 bcm in 2006 (1.65 bcm being Eni’s share). In the medium term, Galp’s sales are expected to grow at an 8% average rate, targeting 6.3 bcm (2.1 Eni’s share) in 2010. Spain Eni operates in the Spanish gas market through Unión Fenosa Gas (Eni’s interest 50%) engaged in natural gas supply and sale to final users and to power generation utilities. In 2006 gas sales of Unión Fenosa Gas in Europe amounted to 4.34 bcm (2.17 bcm Eni’s share). Unión Fenosa Gas is engaged in LNG through an 80% interest in the Damietta liquefaction plant, on the Egyptian coast (see below), and through a 7.36% interest in a liquefaction plant in Oman, completed in 2005; in addition, it holds interests in the Sagunto (Valencia) and El Ferrol (Galicia) regasification plants, with a 42.5% (21.25% Eni’s interest) and 18.9% interest (9.45% Eni’s interest), respectively. Eni targets to increase its sales in the Iberian Peninsula from the current 5.2 bcm level to approximately 8.5 bcm by 2010 (13% average growth rate), mainly as a result of growing sales of Unión Fenosa Gas and the development of direct sales, in particular to the Spanish power generation segment, supplied mainly by means of LNG from Nigeria.

UK/Northern Europe Eni through North Sea Gas & Power unit of its subsidiary Eni UK Ltd sells equity gas produced at Eni’s fields in the North Sea and operates in the main continental natural gas hubs (NBP, Zeebrugge, TTF). Eni plans to grow volumes sold on the UK/North European markets from the current 2.64 bcm level to approximately 8 bcm by 2010, with a 32% average annual growth rate. In particular a significant increase is expected in spot sales on the Zeebrugge hub (from 0.2 bcm in 2006 to 4.2 bcm in 2010). |  | In the UK, gas sales through North Sea Gas&Power are expected to grow from 2.5 bcm in 2006 to 3.8 bcm in 2010, equal to a 3% market share. Turkey Eni sells gas supplied from Russia and transported via the Blue Stream underwater pipeline. In 2006 sales amounted to 3.68 bcm. Leveraging on the expected demand growth, Eni plans to increase sales up to 6.4 bcm by 2010, equal to an 18% market share.

1.3 Supply Eni enjoys a competitive advantage represented by its wide and diversified availability of natural gas both from equity production and from its unrivaled portfolio of long term purchase contracts with major producing countries, also boasting a direct upstream presence in 8 out of 10 gas supplying countries. Our diversified supply portfolio insulates us from the risk of being heavily dependent on a single source of supplies; in fact, none of Eni’s suppliers weighs for more than 25% of Eni current gas needs. In addition, the development of LNG projects will further strengthen the diversification of Eni’s supplies and their integration with upstream operations. In 2006, Eni’s requirements for natural gas were met for over 92% with supplies from foreign countries (mainly Algeria, Russia, the Netherlands and Norway) and the remaining part was covered by equity gas. |  | The strategic agreement with Gazprom, signed in November 2006, marks a fundamental step in enhancing security and flexibility of Eni’s gas supplies over the medium and long term. Based on this agreement, the duration of our long-term supply contracts increases from 14 to approximately 23 years and, when these contracts are fully operational in 2010, Eni will be able to purchase approximately 62.4 bcm/y (Russia 23.5, Algeria 21.5, the Netherlands 9.8, Norway 6, and Nigeria - LNG 1.6) to cope with rising demand according to our sales expansion plans in Europe. Furthermore, Eni can leverage on the flexibility of its contractual structure in order to capture market opportunities, also taking account of Eni’s availability of an integrated system for transport and logistics.

An effective management of relationships with strategic countries supplying natural gas and the preservation of satisfactory long term relations continue to be priorities in running our gas business owing to the strategic clout of the security, diversification, and flexibility of supplies. 2. Infrastructure Overview Eni can access the widest network of infrastructure for transport and storage of natural gas in Europe which favored by its integration allows to link key consumption basins in Europe with the main producing areas (North Africa, Russia and the North Sea). In Italy Eni owns almost all the national gasline network and a relevant system of local distribution networks servicing retail markets. The availability of regasification capacity in Italy and the Iberian Peninsula coupled with storage sites guarantees a high level of operating flexibility. These assets represent a significant competitive advantage. With the aim of increasing diversification and safety of supplies and to cope with demand growth, Eni defined a massive plan for the upgrade of import infrastructure from Russia, Algeria and Libya, of regasification capacity and of national transport and distribution networks through capital expenditure of approximately euro 5.8 billion planned for the next four years. 2.1 International transport activities Eni owns transportation rights in a network of international high pressure pipelines for a total of over 4,300 kilometers allowing the import to Italy of natural gas produced in Russia, Algeria, the North Sea and Libya, in particular: the TAG PIPELINE, 1,140-kilometer long, made up of three lines, each about 380-kilometers long, with a transit capacity3 of 31 bcm/y, related to the build-up of the fourth import contract from Russia, 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. This pipeline is going to be upgraded by 6.5 billion cubic meters/year starting in October 2008 with capital expenditure estimated at about euro 253 million (94% covered by Eni). The capacity of the first upgrade has been assigned to third parties importing natural gas into Italy in February 2006. Procedures have been defined for the assignment of the second upgrade; |  | the TTPC PIPELINE, 742-kilometer long, made up of two lines each 371-kilometers long with a transit capacity of 27 bcm/y 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. This pipeline is going to be upgraded by 6.5 billion cubic meters/year, of these 3.2 starting in April 2008 and 3.3 in October 2008 with capital expenditure estimated at euro 450 million. The capacity of the first upgrade has been assigned to third parties importing natural gas into Italy in 2006. The procedure for the assignation of the second upgrade has been completed in February 2007. The transit capacity of the downstream TMPC pipeline is already adequate to the upgrade of the TTPC; 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 33.5 bcm/y 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 TENP PIPELINE, 1,000-kilometer long (two 500-kilometer long lines) with transit capacity of 15.5 bcm/y 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 20 bcm/y. 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 GREENSTREAM PIPELINE for the import of Libyan gas with a transit capacity of 8 bcm/y 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 and in 2006 transported 7.7 bcm, of which (i) 6.6 bcm to Italian importers under long-term supply contracts targeting a full capacity of 8 bcm/y; (ii) 1.1 bcm of natural gas available from Libyan fields that could not be absorbed by the local market. An upgrade of the pipeline’s transport capacity from 8 to 11 bcm is being planned with an expenditure of euro 80 million to be achieved also with minor interventions for optimizing the transport system. This new capacity will be available from 2011 and will allow to monetize further volumes of natural gas reserves located in Libya through the sale on the Italian market.

(3) |  | Transit capacity is the maximum daily capacity entering in different access points of a trunkline and carried to the next trunkline.

2.2 Italian transport network Eni, through Snam Rete Gas, a company listed on the Italian Stock Exchange, in which Eni holds a 50.04% interest, owns almost completely the Italian natural gas transport network as well as the only regasification terminal operating in Italy. Under Legislative Decree No. 164/2000 concerning the opening up of the natural gas market in Italy, transport activities are regulated by the Authority for Electricity and Gas which determines the methods for calculating tariffs and fixing the return on capital employed. This makes transport a low risk business capable of delivering stable performance in the long period. Eni’s network extends for 30,889 kilometers and comprises: (i) a national transport network extending over 8,497 kilometers, 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 transport network. The national network includes also some interregional lines reaching important markets; (ii) a regional transport network extending over 22,410 kilometers, made up of smaller lines and allowing the transport of natural gas to industries, power stations and local distribution companies of the various local areas served. The major pipelines interconnected with import trunklines that are part of Eni’s national network are: for natural gas imported from Algeria: two lines 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). This pipeline is undergoing an upgrade with the laying of a third line with a 48 inch diameter 328-kilometer long (of these 272 are already operating). Available transport capacity4 at the Mazara del Vallo entry point is approximately 86 mmcm/d; for natural gas imported from Libya: a 36-inch line, 67-kilometer long linking Gela, the entry point of the Greenstream underwater pipeline into the national network near Enna along the import pipeline from Algeria. Transport capacity at the Gela entry point is approximately 30 mmcm/d; |  | for natural gas imported from Russia: two lines with 42/36/34-inch diameters extending for a total length of approximately 900 kilometers that are linked to the Austrian network in Tarvisio and cross the Po Valley reaching Sergnano (near Cremona) and Minerbio. The pipeline is being upgraded by the laying of a third 264-kilometer long line with diameter from 48 to 56 inches; 232 kilometers already operating at the end of 2006, from Tarvisio to Zimella (Verona) and by the upgrading of the Malborghetto compression station. The pipeline transport capacity at the Tarvisio entry point amounts to approximately 101 mmcm/d plus the transport capacity available at the Gorizia entry point of approximately 5 mmcm/d;

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 transport capacity at the Passo Gries entry point amounts to 63 mmcm/d; for natural gas coming from the Panigaglia LNG terminal: one line, with a 30-inch diameter, 170-kilometer long linking the Panigaglia terminal to the national network near Parma. The pipeline transport capacity at the Panigaglia entry point amounts to 13 mmcm/d. In 2006, Eni’s national network of owned pipelines increased by 177 kilometers due to changes to existing lines (87 kilometers) and extensions of the regional network (90 kilometers). Eni’s system is completed by: (i) 10 compressor stations with a total power of 758 MW; (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 for the GreenStream pipeline. The interconnections managed by Snam Rete Gas in the Italian transport network are guaranteed by 25 linkage and dispatching nodes and by 559 plant units including pressure reduction and regulation plants. These plants allow to regulate the flow of natural gas in the network and guarantee the connection of pipes working at different pressures. For the next four years Eni approved a capital expenditure plan of approximately euro 4.2 billion aimed mainly at the upgrade of its transport network in view of the expected increase in import capacity (in particular from Russia and Algeria). 2.3 Regasification - LNG Eni intends to strengthen its integrated LNG business on a global scale, aiming at further diversifying its supply sources, improving operational flexibility, and monetizing its large equity gas reserves. In particular, the development of regasification capacity is aimed at reinforcing and diversifying Eni natural gas supply portfolio. |  | Eni’s main assets in LNG are: Italy Eni owns the only regasification terminal operating in Italy at Panigaglia (Liguria). At full capacity, this terminal can input 3.5 billion cubic meters/year into the Italian transport network. In 2006 a total of 3.12 bcm of natural gas were input in the national network, of these 52% were owned by Eni. Eni plans to build a new regasification terminal located off the Adriatic coast (with a 50% interest) and to increase the capacity of the Panigaglia plant. These two projects are expected to upgrade the import capacity to Italy by 8 and 4.5 bcm/y, respectively, when fully operational. The planned start-up is expected by 2013 and 2014, respectively. The capital expenditure earmarked for the offshore regasification project amounts to approximately euro 800 million (of these euro 400 million for the 50% interest in the offshore regasification plant and euro 359 million for Panigaglia). Egypt Eni, through its interest in Unión Fenosa Gas, owns a 40% stake in the Damietta liquefaction plant producing approximately 5 mmtonnes/y of LNG equal to a feedstock of 7.6 bcm/y of natural gas. In June 2006, the partners of the project (Unión Fenosa Gas, the Spanish-Egyptian company SEGAS an affiliate of Unión Fenosa Gas, State owned Egyptian companies EGAS and EGPC, and oil producers Eni and BP) defined terms and conditions for doubling the plant capacity by means of another treatment train. Expected capital expenditure amounts to approximately $1.5 billion with start-up expected between 2010 and 2011. In order to market its share of natural gas, Eni intends also to build two gas tanker ships with a capacity of 155 kcm each. Spain In April 2006, the Sagunto regasification plant with a capacity of 6.7 bcm/y started operations near Valencia. Eni through Unión Fenosa Gas holds a 21.25% interest in this plant. At present, Eni’s share of regasification capacity amounts to 1.6 bcm/y of gas. A capacity upgrading plan has been sanctioned targeting a 0.8 bcm/y capacity increase by 2009. Relevant works started in the second half of 2006. Eni through Unión Fenosa Gas also holds a 9.5% interest in the El Ferrol regasification plant, located in Galicia, under construction and expected to be completed by the first half of 2007, targeting a treatment capacity of approximately 3.6 bcm/y, 0.4 bcm/y being Eni’s share.

USA Eni is entitled to a share of the initial planned capacity of the Cameron regasification terminal under construction in Louisiana, and expected to start operations in 2008-2009. The 6 bcm/y capacity represents approximately 40% of the initial capacity of the plant (15.5 bcm/y). This transaction will enable Eni to sell part of its gas reserves in the United States. In order to support supplies to this plant, in February 2007 Eni signed an agreement with Nigeria LNG Ltd, operating the Bonny LNG plant in Nigeria, to purchase 1.375 mmtonnes/y of LNG, equivalent to 2 bcm/y of gas for a twenty-year period, gas deriving from the upgrade of the Bonny liquefaction plant (7 trains) expected for 2012. Eni also signed a memorandum of intent with Brass LNG for the purchase of 1.67 mmtonnes/y equivalent to 2.3 bcm/y, of LNG. 2.4 Distribution activities Distribution involves the delivery of natural gas to residential and commercial consumers 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 1,317 |  | municipalities through a low pressure network consisting of approximately 49,000 kilometers of pipelines supplying 5.6 million customers. Under Legislative Decree No. 164/2000 concerning the opening up of the natural gas market in Italy, distribution activities are regulated by the Authority for Electricity and Gas which determines the methods for calculating tariffs and fixing the return on capital employed. This makes distribution a low risk business capable of delivering stable performance in the long period. The management of networks is entrusted to natural gas companies by local Authorities exclusively under bid procedures. Concessions existing at the coming into force of Legislative Decree No. 164/2000 and awarded with a bid procedure expire on December 31, 2012; all other concession expire on December 31, 2007 (with an optional three-year extension under certain conditions). Eni intends to optimize its concession portfolio maintaining its current size in terms of end users served by focusing on development initiatives in core areas and promoting local alliances aimed at supporting sale activities on retail markets.

3. Power Generation Eni engages in power generation activities in its power stations at Ferrera Erbognone, Ravenna, Livorno, Taranto, Mantova, Brindisi and Ferrara. In 2006, electricity production sold was 24.82 TWh, up 2.05 TWh or 9% as compared to 2005. Increased production reflected the ramp-up of the Brindisi plant. Total installed capacity was 4.9 GW at December 31, 2006. By 2010 Eni intends to complete its plan for expanding power generation capacity, targeted at an installed capacity of 5.5 GW fully operational in 2010 with production amounting to 31 TWh, corresponding to approximately 8% of electricity generated in Italy at that date. When fully operational, natural gas volumes |  | supplied will amount to 6 bcm/y from Eni’s diversified supply portfolio. Planned capital expenditure amounts to approximately euro 2.4 billion, of these works for euro 2 billion have already been completed. The development plan is underway at Ferrara (Eni’s interest 51%), where in partnership with EGL Luxembourg (a company belonging to Swiss group EGL) construction of two new 390 MW combined cycle units is underway. This will bring installed capacity to 840 MW (two CGT for a total of 780 MW in addition to the existing 60 MW units) with start-up expected in 2007. Eni has also planned the installation of a new 240 megawatt combined cycle unit located in Taranto (current capacity 75 megawatt).

New installed generation capacity uses the combined cycle gas fired technology (CCGT), ensuring a high level of efficiency and low environmental impact. In particular, management estimates that for a given amount of energy (electricity and heat) produced, the use of the CCGT technology on a production of 30 TWh reduces emissions of carbon dioxide by approximately 11 mmtonnes, as compared to emissions using conventional power generation technology5. |  | Restructuring of power generation activities and dual offer In 2006 the G&P division launched a restructuring plan of its power generation activities, which provides for the transfer of electricity marketing activities from EniPower, the company that had managed them since its establishment, to the division starting in 2007. This will allow an integrated management of Eni’s gas-electricity portfolio and to develop a combined electricity/gas offer to customers. Power generation activities will remain at EniPower.

(5) |  | Eni power plants in operation and under construction employ the combined cycle technology, the most efficient technology currently available for power generation, with 12% higher efficiency than the most upstead coal-fired plants and lower polluting emissions per kWh produced.

ENI FACT BOOK / REFINING & MARKETING - HIGHLIGHTS

2006 Highlights In 2006, adjusted net profit was down euro 316 million to euro 629 million, or 33.4%, mainly due to a decline in refining margins as a result of a weak trading environment and to lower results from marketing in Italy. Eni’s realized refining margins recorded a better trend than market reference margins reflecting Eni’s refineries capacity to process heavy crudes which are discounted as compared to the Brent crude market benchmark, thus resulting in a higher profitability of the heavy barrel. Return on average capital employed adjusted was 10.7%, down from 2005 (18.2%). Capital expenditure totaled euro 645 million and mainly related to projects aimed at improving flexibility and yields of refineries and upgrading the retail network in Italy and in the rest of Europe. Refining throughputs on own account in Italy and outside Italy (38.04 mmtonnes) declined by 750 ktonnes from 2005, down 1.9%, mainly owing to longer unplanned maintenance standstills, particularly at third party refineries (Priolo), while wholly-owned refineries achieved stable processing levels. Total refinery intake amounted to 39.56 mmtonnes, of which 35 in Italy, with full balanced capacity utilization. |  | Retail sales of refined products in Italy (8.66 mmtonnes) declined 1% from 2005 mainly due to competitive pressure. This decrease was more than offset by a growth in retail volumes marketed in the rest of Europe (3.82 mmtonnes, up 4.1%), mainly in Germany and Spain. Sales on the wholesale market in Italy (10.06 mmtonnes) were down 4% due primarily to a decline registered in the fourth quarter owing to the impact of mild weather conditions. This decline was partially offset by a growth in volumes marketed on wholesale markets in the rest of Europe (4.6 mmtonnes, up 2.2%) in particular in Germany and Spain.

Activities 1. Refining Eni owns five refineries in Italy and interests in refineries located in Italy, Germany and the Czech Republic with a total refining capacity (balanced with conversion capacity) of approximately 35.5 million tonnes (equal to 710 kbbl/d) and a conversion index of 57%. Eni’s wholly owned refineries in Italy have a balanced capacity of 26.7 mmtonnes (equal to 534 kbbl/d), with a 58.9% conversion rate. In 2006 refining throughputs on own account in Italy and outside Italy were 38.04 mmtonnes; total throughputs on wholly owned refineries were 27.17 mmtonnes (on own account and for third parties), with full balanced capacity utilization. In the medium term, Eni forecasts the refining environment to be featured by the following trends: (i) global imbalances in the availability of products among macro geographic areas; (ii) a low adequacy of existing refining assets to process heavy and non conventional feedstock against a backdrop of persisting high spreads between light/sweet and heavy/sour crude qualities; (iii) an imbalance of existing refining assets towards higher yields in gasoline and fuel oil in contrast with rising demand for middle distillates; |  | and (iv) increasingly tight environmental and product quality regulations which make the upgrading of existing refining assets a critical issues. Against this backdrop, Eni plans to enhance the profitability of its refining business, capturing opportunities arising from current market trends by implementing a large investment program of approximately euro 3 billion in the next four years. Principal planned actions are to: (i) increase primary and conversion capacity, targeting a complexity index higher than 57%, in view of boosting middle distillate yields, including petrochemical feedstock, and extracting value from equity crude, the availability of which is expected to increase in the Mediterranean basin over the medium term; (ii) improve refinery flexibility in order to optimize processed feedstock and capture market opportunities arising from an expected increasing availability of heavy/sour crude which can be purchased at a discount in the marketplace; (iii) achieve high-quality products responsive to expected demand trends and the evolution of product specifications provided for by increasingly tight European standards in term of emissions and environmental preservation; (iv) strengthen vertical integration with upstream and petrochemical operations; and (v) enhance operational efficiency of refineries, targeting in particular a higher level of energy efficiency.

ITALY Eni’s refining system in Italy is composed of five wholly owned refineries and a 50% interest in the Milazzo refinery in Sicily. Each of Eni’s refineries in Italy has operating and strategic features that aim at maximizing the value associated to the asset structure, the geographic positioning with respect to markets and the integration with Eni’s other activities. SANNAZZARO: with a balanced primary refining capacity of 170 kbbl/d and an equivalent conversion index of 46.2% is one of the most efficient refineries in Europe. Located in the Po Valley, it supplies mainly markets in North-Western Italy and Switzerland. The high degree of flexibility of this refinery allows it to process a wide range of oils, such as CPC Blend crude oil from the Caspian Sea carried through the CPC pipeline, the Bonga crude from Nigeria and oil from Eni’s Villafortuna field. 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. |  | This refinery contains two primary distillation plants and a vacuum unit. Conversion is obtained through a fluid catalytic cracker (FCC1), an HDCK middle distillate conversion unit and a visbreaking thermal conversion unit. Two catalytic reforming plants, an isomerization plant, an alkylation plant, an MTBE plant and three desulphurization plants for middle distillates and one for naphtha from cracking complete the production cycle. In 2006, Eni completed a gasification facility using the heavy residue from visbreaking (tar) to produce syngas to feed the nearby EniPower power station at Ferrera Erbognone. Eni plans to upgrade this refinery, targeting to transform it into a world class plant. In particular, in the next four years, Eni plans to build: a high pressure hydrocracking unit with a capacity of 28 kbbl/d, able to produce over 1 mmtonnes/y of high quality middle distillates, in particular diesel fuel with low sulphur content and kerosene. Start-up is planned at 2008 end;

a PDA deasphalting unit with a 28 kbbl/d capacity for the production of deasphalted oil (without asphaltene and metals) from visbreaking and vacuum unit residues to be used as feedstock for the FCC unit. Further residues will be used as feedstock for the tar gasification plant. The deasphalting plant will enable Eni to increase the refinery’s flexibility thanks to the processing of a higher amount of high sulphur content crude, thus increasing the yield of valuable products (diesel fuel). Start-up is planned in 2008. Eni is currently evaluating the building of a plant employing Eni Slurry Technology (see “Innovative technologies”, below) with a 23 kbbl/d capacity for the processing of extra heavy crudes and tar sands producing higher quality products, in particular diesel fuel, and reducing the yield of fuel oil to zero. TARANTO: with a balanced primary refining capacity of 110 kbbl/d and an equivalent conversion index of 61.1%, 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 southern Italian markets. Besides its primary distillation plants, this refinery contains a flash vacuum unit, two plants for the desulphurization of middle distillates, a reforming unit, an isomerization unit and conversion plants such as: a two-stage thermal conversion plant (visbreaking/thermal cracking) and an RHU conversion plant, that allows to convert high sulphur content residues into valuable products and cracking feedstocks. It processes most of the oil produced in Eni’s Val d’Agri fields carried to Taranto through the Monte Alpi pipeline (in 2006 a total of 3.157 mmtonnes of this oil were processed). Eni plans to develop and upgrade this refinery, targeting to transform it into a world class one. In particular, two projects are planned: (i) the building of a new high pressure hydrocracking unit with a 17 kbbl/d capacity and the revamping of the hydrogen production unit; these assets will allow to produce approximately 0.6 mmtonnes/y of high quality gasoil, when fully operational. Start-up is planned in 2008; (ii) the building of a new topping2 unit with a 4 mmtonnes/y capacity and an associated vacuum unit with a 2.5 mmtonnes/y capacity. Eni also plans to build a new unit for the desulphurization of middle distillates with a 2.3 mmtonnes/y capacity, in addition to utilities and logistic facilities |  | (see “Logistics”, below), in particular a pipeline for transporting virgin naphtha to Eni petrochemical plant at Brindisi. The objective is to expand the consumption area covered by the refinery to Campania. Start-up is expected in 2009/2010. This development and upgrading plan will enable Eni to better employ national and Caspian equity crude and give more flexibility to this refinery, optimizing the use of the conversion plants and increasing throughput from 6 to 10 mmtonnes/y (100-180 kbbl/d). GELA: with a balanced primary refining capacity of 100 kbbl/d and an equivalent conversion index of 143.5% 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 go-finer for the upgrading of 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. It also contains two reforming units, an alkilation unit, an MTBE unit and plants for desulphurization of gasoil and naphtha from cracking. The power plant of this refinery also contains modern residue and exhaust fume treatment plants which allow the complex to comply with the most exacting environmental standards. An upgrade of the Gela refinery will be implemented by means of an upgrade of topping capacity to enable higher intakes (approximately 1 mmtonnes/y) and of feedstock flexibility. In addition, actions to improve energy efficiency, renewal of facilities for gasoline production, and the upgrade of utilities and the logistic reorganization of the site are planned. LIVORNO: with a balanced primary refining capacity of 84 kbbl/d and an equivalent conversion index of 11.4%, manufactures mainly gasolines, fuel oil for bunkering, specialty products and lubricant bases.

(2) |  | Topping (also called atmospheric distillation) represents the first stage of primary distillation of crude aimed at separating products thanks to the different boiling temperatures of the hydrocarbons contained in crude.

Besides its primary distillation plants, this refinery contains a vacuum unit, a reformer unit, an isomerization plant, two desulphurization units for middle distillates and two lubricant manufacturing lines. Its pipeline links with the local harbor and with the Florence storage sites by means of two pipelines optimizing intake, handling and distribution of products. PORTO MARGHERA: with a balanced primary refining capacity of 70 kbbl/d and an equivalent conversion index of 22.8%, supplies mainly markets in north-eastern Italy, Austria, Slovenia and, at a lower extent, Croatia. Besides its primary distillation plants with vacuum plants, this refinery contains a reformer plant, an isomerization plant, two gasoil desulphurization units and a two-stage thermal conversion plant (visbreaking/thermal cracking) for increasing yields of valuable products. The plant upgrading project, subject to the extension of the refining license, concerns the construction of a new hydrocracker with a 24 kbbl/d capacity and upgrades of utilities. The objective is to increase intake (up 1.4 mmtonnes/y, to approximately 5.5 mmtonnes when fully operational), the improvement of flexibility in processed feedstocks, the increase in middle distillates produced (up 0.7 mmtonnes) in an area characterized by structural diesel fuel deficit, and higher energy efficiency. REST OF EUROPE In Germany Eni holds an 8.3% interest in the SCHWEDT refinery and a 20% interest in BAYERNOIL, an integrated pole that includes the Ingolstadt, Vohburg and Neustadt refineries. Eni’s refining capacity in Germany amounts to approximately 70 kbbl/d. Eni’s share of the production of the three integrated refineries and of the Schwedt refinery is mainly used to supply Eni’s distribution network in Bavaria and Eastern Germany. Eni plans to restructure the Bayernoil refining pole, by building a new hydrocracker with a capacity of approximately 2 mmtonnes/y, revamping other assets (in particular a reformer and a hydrofiner) and shutting-down a topping unit. Eni holds a 16.33% interest in CESKA RAFINERSKA which owns and manages two refineries, Kralupy and Litvinov, in the Czech Republic. Eni’s share of refining capacity amounts to 27 kbbl/d. 2. Logistics Eni is leader in storage and transport of petroleum products in Italy with its logistical integrated |  | infrastructure consisting of 12 directly managed storage sites and a network of petroleum product pipelines. Eni holds interests in five joint entities established by partnering the major Italian operators. These are located in Vado Ligure-Genova (Petrolig), Arquata Scrivia (Sigemi), Venice (Petroven), Ravenna (Petra) and Trieste (DCT) and aim at reducing logistic costs, and increasing efficiency. Eni operates in the transport of oil and refined products: (i) on land through a pipeline network of leased and owned pipelines extending over 3,210 kilometers (1,513 kilometers are wholly owned by Eni); (ii) by sea through spot and long-term lease contracts of tanker ships. For the distribution of refined products to retail and wholesale markets, Eni owns a fleet of tanker trucks and manages third-party owned vehicles. In the medium-term, Eni plans to enhance the relationship between its logistic and refining operations by implementing an integrated logistic model (“hub” model) designed to centralize handling of products flows on a single platform enabling real time monitoring. In the next four years, Eni plans to invest approximately euro 0.6 billion directed in particular to the implementation of the Taranto logistic project intended to support the refinery’s development plan: a new diesel fuel and gasoline storage site will be built in Campania and three pipelines will be laid, two of which linking the refinery to the storage site and the other one to transport virgin naphtha to Eni’s petrochemical complex in Brindisi. The objective of this plan is to eliminate the transport of refined products by sea to Naples. 3. Marketing RETAIL SALES In retail distribution Eni intends to enhance its leadership on the Italian retail market, improving outlets and service quality standards and targeting a strong product differentiation and customer-oriented promotional initiatives. In the rest of Europe, Eni will selectively grow its market share, targeting a strengthening of its competitive positioning in selected markets, leveraging on synergies achievable thanks to the geographic location of its production and logistic assets and on strong brand awareness.

ITALY Eni is leader in the retail marketing of refined product under its Agip brand. At December 31, 2006, Eni’s retail distribution network consisted of 4,356 Agip branded service stations with sales amounting approximately to 11 billion liters (8.66 mmtonnes) with an average throughput of 2.46 mml and a 29.3% market share. Eni intends to strengthen its competitive positioning in Italy by introducing new outlet formats in line with European standards of quality and services, increasing premium products sales and differentiating promotional offers in order to retain the various segments of clients. A strong focus will be devoted to pursue high levels of operating efficiency. In the next four years, Eni plans to invest approximately euro 0.75 billion in the upgrading of its network, targeting to build and acquire new service stations, highgrade/restructure existing ones, and to adequate them to applicable environmental standards and regulations. By 2010, Eni expects to have a retail network |  | composed of approximately 4,360 service stations with an average throughput of approximately 2.7 bl per outlet. As for “premium price” products, Eni intends to enhance its “Blu fuel” line of products by launching a new diesel fuel with high environmental quality and engine performance. In 2006, sales of BluDiesel – a high performance virtually sulphur free diesel fuel that improves engine performance – on the Agip branded network amounted to approximately 840 bl (760 mmtonnes), a decline of 14.8% from 2005 due mainly to the increasingly high sensitivity of consumers to the price of fuels in light of their remarkable increase in the year. At 2006 year-end, service stations marketing BluDiesel were 4,061 (about 4,000 at 2005 year-end) corresponding to approximately 93% of Eni’s Agip branded network. Retail volumes of BluSuper – a high performance and low environmental impact gasoline – amounted to about 114 mml (98 ktonnes), down 9% from 2005,

showing a trend similar to the one of BluDiesel. At 2006 year-end, service stations marketing BluSuper were 2,316 (about 1,719 at December 31, 2005) corresponding to approximately 53% of Eni’s network. In January 2006 Eni started the experimental marketing of Ad-Blue®, a water solution containing urea for technologically advanced heavy duty vehicles. This additive, compatible with the new characteristics of most trucks built in Europe, reacts with exhaust gases reducing emissions and consumption and improving engine performance. In 2006 Eni continued its Do-It-Yourself campaign which enables customers accessing self-service outlets with an electronic card to obtain price discounts or gifts (under agreements with Vodafone and Coop) in proportion to the total amount of purchased fuel. Further bonuses are offered to the most faithful customers. At year-end the number of active cards was about 3.9 million; turnover on cards increased by 3% from 2005. The amount of fuel purchased with cards was approximately 39% of all fuels marketed on Agip branded service stations joining the campaign, corresponding to about 31% of total Agip throughput. You&Agip In March 2007, Eni launched its You&Agip promotional campaign designed to boost customer loyalty to the Agip brand. It is an innovative formula intended to outperform traditional loyalty programmes for motorists, mainly by cancelling the usual time limits, as it is set to last for the next three years until December 31, 2009. Furthermore, the list of prizes will be kept constantly updated thanks to the high numbers of partners joining the initiative. Just to mention a few qualifying features of the You&Agip programme, customers can decide how to accumulate points, when to spend them and what kind of reward to choose. Points can be accumulated not only by buying fuels, but also by buying all the other services and wares sold at AgipCafè outlets. In 2006, Eni continued the initiative of the European Multicard Routex paying card addressed to professional transport (transporters and car fleets) with sales of 1.5 bl (up 4.7% from 2005), and the number of customers provided with this card increased by about 2,000 to 52,000 users at year end. Multicard is used internationally and is part of the international Routex consortium, made up by Agip, Aral, BP, OMV and Statoil. 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 and services to customers, in particular 1,000 cafè |  | and fast food outlets as well as innovative commercial outlets. To this end Eni owns master franchisor rights with exclusive rights for the oil sector for the “Pans & Co” brand, a leader in quality fast food outlets. Eni’s network contains 13 Pans & Co outlets and 32 McDonald’s outlets both on ordinary and motorway assets. In 2006, a total of 70 new affiliations were added to the AgipCafè® branded outlets and by year end a total of 340 franchises. Moreover, 9 new convenience stores under the “SpazioAgip®” brand name were opened, thus reaching a total of 23 locations. Also 45 new car-wash facilities were opened on Agip owned service stations, thus reaching a total of 715 units. In particular the travellers who stop at Agip branded stations along the motorways can access a wide range of services: AgipCafè, l’Angolo del Buongustaio, SpazioAgip, RistorAgip, BabyRoom and special rest areas dedicated to motor homes. Eni has also developed the AgipTruck Point, large-format specialized service stations for heavy duty vehicles where facilities have been created for truck drivers such as secure parking and IT services. In the next four years Eni intends to continue the development of its non-oil activities and expects to provide 57% of its Agip branded network with these facilities by 2010 (53% in 2006). REST OF EUROPE In 2006, retail volumes of fuels marketed in the rest of Europe totalled 4.8 bl (3.82 mmtonnes). At December 31, 2006, Eni’s retail marketing network outside Italy was represented by 1,938 service stations with an average throughput of 2.5 mml. The areas where Eni’s presence is significant are South-Central Germany with a 4.4% market share, Spain with 3.2%, Austria with 7.2%, Switzerland with 5.8% and South-Western France with 1.2% on national base. In recent years, Eni’ s strategy focused on selectively growing its market share, also by means of acquisition of assets, in European areas with interesting profitability perspectives mainly in Central-Eastern Europe (in particular Southern Germany, Austria, the Czech Republic and Hungary) in South-Eastern France and the Iberian Peninsula. In pursuing such growth, Eni has been able to reap synergies deriving from said areas being close to Eni’s production and logistic facilities. Over the past five years, retail volumes of refined products marketed in the rest of Europe have grown more than 50% (equal to a 9% compound average growth rate). By 2010 Eni expects to market approximately 5.6 bl. Growth in volumes will be achieved through acquisitions, leasing and construction of new service stations with high quality standards,

automation and throughput, also leveraging on marketing campaigns aimed at enhancing the Agip brand perception on markets. By 2010 Eni plans to have a network of approximately 2,180 service stations with an average throughput of 2.6 bl. Non-oil activities in the rest of Europe are carried out under the “CiaoAgip” brand name in 1,158 service stations, of these 328 are in Germany and 169 in France with a 60% coverage of the network and the virtually complete coverage of owned stations. MultiEnergy The attention paid to environmental considerations led to the construction of Multienergy service stations that are equipped with solar panels able to provide all the energy necessary for their functioning and that sell a full range of fuels with a significant environmental value. The inauguration of the Agip MultiEnergy service station at the Infraserv Höchst industrial park in Germany, marks the conclusion of the first phase of the “Zero Regio” project, which has the support of the European Commission, for the construction of an innovative “multifuel” station for the supply and trial of zero emission vehicles fuelled with hydrogen. 4. Other businesses Wholesale marketing and other sales Eni markets gasoline and other fuels on wholesale markets, including diesel fuel for automotive use and for heating purposes, for agricultural vehicles and for vessels, gasoline and fuel oil. Major customers are wholesalers, agricultural users, manufacturing industries, public utilities and transports. Eni provides its customers with its expertise in the area of fuels with a wide range of products that cover all market requirements. Along with traditional products provided with the high quality Eni standard, there is also an innovative low environmental impact line, which includes AdvanceDiesel especially targeted for heavy duty public and private transports. Customer care and product distribution is supported by a widespread commercial and logistical organization present all over Italy and articulated in local marketing offices and a network of agents and concessionaires. In 2006 volumes marketed on wholesale markets in Italy, which excludes the Avio and Bunker businesses, were 8.22 mmtonnes down 610 ktonnes from 2005, or 7%, due mainly to a decline in domestic consumption related to mild weather conditions in the fourth quarter of the year. |  | Sales volumes on wholesale markets outside Italy were 4.27 mmtonnes, up approximately 100 ktonnes from 2005, or 2.6%, reflecting mainly higher sales in Germany and Spain. Eni also markets jet fuel directly at 38 airports, of which 27 in Italy. In 2006, these sales amounted to 2.18 mmtonnes (of which 1.84 mmtonnes in Italy) up approximately 200 ktonnes. Eni is active also in the international market of bunkering, marketing marine fuel in 38 ports, of which 23 in Italy. In 2006 marine fuel sales were 1.9 mmtonnes (1.24 in Italy) increasing 100 ktonnes. Other sales were 22.09 mmtonnes of which 19.48 mmtonnes referred to sales to oil companies and traders, and 2.61 mmtonnes supplies to the petrochemical sector. LPG In Italy Eni is leader in LPG production, marketing and sale with 589 ktonnes sold for heating and automotive use (under the Agip brand and wholesale) equal to an 18% market share. Additional 350 ktonnes of LPG were marketed through other channels mainly to oil companies and traders. LPG activities in Italy are supported by direct production, availability from 11 bottling plants and a number of owned storage sites in addition to products imported at coastal storage sites located in Livorno, Naples and Ravenna. Lubricants Eni operates 8 (owned and co-owned) blending plants, in Italy, Europe, North and South America, Africa and the Far East which manufacture finished and fatty lubricants. With a wide range of products composed of over 650 different blends, Eni masters international state-of-the-art know-how for the formulation of products for vehicles (engine oil, special fluids and transmission oils) and industries (lubricants for hydraulic systems, industrial machinery and metal processing). In Italy Eni is a leader in the manufacture and sale of lubricant bases. Base oils are manufactured primarily at its refinery in Livorno. Eni also owns one facility for the production of additives and solvents in Robassomero. In 2006, retail and wholesale sales in Italy amounted to 136 ktonnes with a 24.9% market share. Eni also sold approximately 4 ktonnes of special products (white oils, transformer oil and anti-freeze fluids). Outside Italy sales amounted to approximately 102 ktonnes, of these about 50% were registered in Europe (mainly Germany, Netherlands and Spain).

Technological innovation

Eni’s commitment to technological research and innovation underscores a fundamental belief that technology is key to increase our competitive advantage over the long term and promoting sustainable growth. Future global challenges require ingenuity and commitment: from the environmental and climate issues to the increasingly difficult access to hydrocarbon reserves large, but mainly controlled by producing countries; from the identification of relevant discontinuities in the production of energy from renewable sources to the optimization of production processes up to solution of problems existing in countries where Eni has been present for a long time or where it recently entered. Eni is conducting research aimed primarily at reducing the costs of finding and recovering hydrocarbons, upgrading heavy oils, monetizing stranded gas and protecting the environment. Over the next four years Eni intends to invest 1.5 billion euros to support its research and development (R&D) strategy. More specifically, Eni’s main R&D fields regard: reserve replacement and reduction of mineral risk; production and monetization of non-conventional hydrocarbon reserves and optimal management of reserves with high hydrogen sulphide and sulphur content; delivering more gas to market, monetizing associated gas and stranded gas; improvement of fuel quality and performance in light of the evolution of engines to increasingly perfected and efficient systems with lower impact on the environment; and efficient use of fossil fuels through an improvement in refining yields and an optimal use of each fuel entailing a lower environmental impact. |  | Referring to environmental protection, Eni intends to develop the “Along with Petroleum” program aimed at identifying and developing research projects on the most advanced aspects of large scale use of renewable energy sources and energy efficiency. In particular, Eni expects to devote a great deal of focus on the fields of the mitigation of the greenhouse effect, through the capture and geological sequestration of carbon dioxide, the bio-fuels, the photovoltaic, the solar energy and the hydrogen production by renewable sources. In 2006 Eni invested euro 222 million (204 in 2005), of these 39% were directed to the Exploration & Production segment, 32% to the Refining & Marketing segment, 22% to the Petrochemical segment and 7% to the Engineering & Construction segment. At December 31, 2006, a total of 1,160 persons were employed in research and development activities. In 2006 a total of 39 applications for patents were filed. A description of the main technologies under development or currently applied is provided below. Main technological innovation projects Advanced Drilling Systems and Well Testing Eni developed significant industrial applications of innovative technologies enabling to drill highly complex wells with greater operating efficiency. The “Geosteering” project developed by Eni in joint venture with Shell aims at the development of technologies capable of providing geological information on not yet drilled layers, (around the scalpel up to the surface) while drilling.

ENI FACT BOOK / TECHNOLOGICAL INNOVATION

In the first six months of 2006, various down hole prototypes have been made and in the second half of the year the technology was tested in a well. Testing is expected to continue until the first half of 2007. Referring to drilling activities, some new technologies have been tested: Extreme Lean Profile, development of “slim” field techniques applicable also to fields with narrow diameter; Eni Circulation Device, avoiding the danger of “keep of the bars” during the drilling activity; Light Drill Pipe, based on the usage of aluminum bars in strongly deviated wells; Zero Emission Well Testing, evaluation methodology of the characteristics of a new field by fluids injection (that is to say with no emission) based on know-how and Eni’s software, instead of on conventional production tests prove “in hydrocarbons supplying”. Numeric and High Resolution Geophysical Prospecting Techniques The development of a simulator of oil systems “Steam 3D” has been completed. It enables to describe the evolution of complex geological structures in time. Development continued of the proprietary CRS technology (3D Common Reflection Surface Stack) that aims at allowing prospecting in areas characterized by low seismic response. First application of the following technologies has been done: CSEM (Controlled Source ElectroMagnetic), which enables data collecting on the presence of pre-drilling hydrocarbons, reducing explorative risk and improving the reliability in the definition of the reservoir extension, through the measurement of the electric drag of structure in the sea field; |  | “Multipoint Statistic” and “Process Oriented Modelling” improving the characterization and the localization of reserve that can be produced from a specific reservoir; “Integrated Asset Modelling”, which optimizes the development and the production of a field through the integration of field models and on-shore facilities; Regarding to the production optimization in “tight reservoirs”, first application of a proprietary technology has been made aiming to foresee the increase of productivity achievable by operations on induced fractures. Sulphur management In 2006 the integrated research program Sulphur and H2S management in E&P operations related to the handling of gas with high H2S content has been completed. An innovative proprietary system called Concrete Wall for the massive storage of sulphur and a bulk removal technology of H2S have been developed. In 2007 demonstration facilities for the handling and storage of sulphur are expected to be developed along with a study regarding the behavior of materials in very sour environments and under extreme pressure and temperature conditions. Gas to Liquids (GTL) The conversion of gas to liquids is a key technology for the use of natural gas on a large scale for the production of high quality fuels, in particular diesel fuel and therefore it receives special attention by all oil majors due to its strategic value.

In 2006 in cooperation with IFP/Axens, Eni completed the technology handbook for this proprietary technology for the conversion of gas to liquids via Fischer-Tropsch synthesis and the basic engineering of a 37 kbbl/d industrial unit. In 2007 some issues will be addressed regarding the risks of the transition to the subsequent industrial scale: mechanic validation on the maximum industrial scale of the catalyst for the FT synthesis; validation of the mechanic design carried out by referenced builders of the reactor to be applied to the maximum industrial scale; tweak of a scheme on the treatment of water produced in the synthesis process. |  | Conversion of heavy crude and fractions into light products Testing continued at the Taranto demonstration plant of Eni’s proprietary technology EST, a process of catalytic hydroconversion in the slurry phase of non conventional crude, extra heavy crude and refining residues that allows to convert asphaltenes (the hard fraction of heavy crude) totally into naphtha, kerosene, diesel fuel. In particular, a four-month test period has been carried out using a residue from a Canadian tar sand, confirming expected conversion yields and performance stability. In 2007 Eni plans to complete the collection of information for designing and building its first industrial plant.

Taranto demonstration plant of Eni’s proprietary technology EST SCT-CPO Project (Short Contact Time - Catalytic Partial Oxidation) At the Milazzo research center the SCT-CPO (partial catalytic oxidation with short contact time of liquid and gaseous hydrocarbons) technology has been validated on the pilot scale for producing hydrogen at competitive costs, also in medium to small sized plants with higher flexibility as compared to refinery feedstocks. In 2007 Eni plans to complete the collection of information for designing and building its first industrial plant. Natural gas high pressure transport (TAP) The TAP project will contribute to developing the most advanced long distance, high capacity, high pressure and high grade solutions with relevant targets related to: transport on distances over 3,000 kilometers; natural gas volumes to be transported of about 20-30 bcm/year; pressure equal to or higher than 15 MPa; use of high and very high grade steel. The TAP technology is expected to allow a decrease in the consumption of natural gas used in compressor stations. |  | In 2006 testing continued on two infrastructures: one made of steel at a high resistance X80, with a length of about 10 km integrated in the system of Snam Rete Gas; two pilot portions (750 meters of length) made of steel at a high resistance X100, run at a constant pressure in a range of 135 to 150 bar. After completing the pressure test on these two pilot portions, a test spreading a cracking on one of them has been scheduled. In 2006 the first technology handbook version was published and a hypothetical 3,400-kilometer long gasline in X100 steel from the Karachaganak field (western Kazakhstan) was designed. Environmental protection In 2006 continued the development of technological solutions aimed at minimizing the environmental impact of the exploration, refining and utilization of hydrocarbon. Referring to the CO2 conversion in energy vectors via biofissation, in 2007 will be evaluated the opportunity to test it on a demonstrative scale. Among the main activities undertaken or started in 2006, the following projects are highlighted: Green Diesel – the project aims at the production of biodiesel in refineries by means of a new hydrocracking process using vegetable oils and will be developed in cooperation with an international partner; Ensolvex – aimed at the further industrial application of the process for the reclaiming of soils polluted by organic substances; EWMS (Early Warning Monitoring System) – in-field application of the outcome of research on remote monitoring and advanced control. GHG Project (Green House Gases) Work continued on the integrated Green House Gases research program, aimed at verifying the industrial feasibility of the geological sequestration of CO2 in depleted fields and salty aquifers. The technical feasibility study of the geological sequestration of CO2 has been completed and in 2007, Eni expects to start testing in the field.

It also started a new phase of its clean diesel fuel program aiming at identifying the optimal formula for a diesel fuel with high performance and low particulate emissions using as benchmark GTL Fischer-Tropsch diesel oil (obtained from the conversion of natural gas into liquids - GTL project). Research activities will be conducted on the design of refining facilities for producing this product. A process of hydro-dearomatization of certain refining feedstock with a high content of aromatics (e.g. the light cycle oil produced by fluid catalytic crackers) is being developed. A double-function, proprietary catalyst has been developed able to reduce hydrogen consumption and certain by-products. The project is progressing on a pilot scale. Monitoring on the mock-up distribution of the “ADBlue” in the Agip corner sale, at Assago Ovest (MI) continued. The ADBlue (Water solution with urea at 32.5%) can be used to remove nitrogen oxide (NOx) |  | from exahaust gas of Diesel commercial motors with catalytic disposal for the selective reduction of NOx (Selective Catalytic Reactor). Bio fuel and heavy crude conversion: deal with Petrobras As part of the development of technologies aiming at the enhancement of fuel quality and at the conversion of heavy crude and fractions into light products, in March 2007 Eni signed an agreement with Petrobras, the world’s leading company in the large-scale production of bio-ethanol. The two partners will combine their proprietary technologies to jointly develop projects for the production of bio-fuels in other countries. In addition, they will study joint projects to assess the application of the Eni Slurry Technology (EST) in Brazil in the framework of a broader partnership involving both upstream and downstream joint initiatives.

Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Further, finance charges on finance debt, interest income, charges or income deriving from the fair value evaluation of derivative financial instruments held for trading purposes, and exchange rate differences are excluded when determining adjusted net profit of each business segment. Taxation effect of such items excluded from adjusted net profit is determined based on the specific rate of taxes applicable to each item, with the exception of finance charges or income, to which the Italian statutory tax rate of 33% is applied. Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them to facilitate comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment. The following is a description of items which are excluded from the calculation of adjusted results. Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold in the period calculated using the weighted-average cost method of inventory accounting. Special items include certain relevant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non- |  | recurring items under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past exercises or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non recurring material income or charges are to be clearly reported in the management’s discussion and financial tables. Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition the effect of the fair value evaluation of derivative financial instruments held for trading purposes and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charges pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of asset retirement obligations in the Exploration and Production division). Finance charges or interest income and related taxation effects, excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies. For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and net profit see tables below.

ENI FACT BOOK / SUPPLEMENTAL OIL AND GAS INFORMATION

Supplemental oil and gas information

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. Net proved reserves exclude royalties and interests owned by others. Proved developed oil and gas 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. Eni’s proved reserves have been estimated on the basis of the applicable U.S. Securities & Exchange Commission regulation, Rule 4-10 of Regulation S-X and its interpretations and have been disclosed in accordance with Statement of Financial Accounting Standard No. 69. The estimates of proved reserves, developed and undeveloped for years ended December 31, 2003, 2004, 2005 and 2006 are based on data prepared by Eni. Since 1991, Eni has requested qualified independent oil engineering companies carry out an independent evaluation1 of its proved reserves on a rotational basis. In particular a total of 1.4 billion boe of proved reserves, or about 21% of Eni’s total proved reserves at December 31, 2006, have been evaluated. The results of this independent evaluation confirmed Eni’s evaluations, as in previous years. In the 2004-2006 three-year period, 76% of Eni’s total proved reserves were subject to independent evaluations. Eni operates under Production Sharing Agreements, (PSAs), in several of the foreign jurisdictions where it has oil and gas exploration and production activities. Reserves of oil and natural gas to which Eni is entitled under PSA arrangements are shown in accordance with Eni’s economic interest in the volumes of oil and natural gas 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 represented 51%, 48% and 53% of total proved reserves as of year-end 2004, 2005 and 2006, respectively, on an oil-equivalent basis. A similar scheme to PSAs applies to Service and “Buy-Back” contracts; proved reserves associated with such contracts represented 3%, 2% and 2% of total proved reserves on an oil-equivalent basis as of year-end 2004, 2005 and 2006, respectively. Oil and gas reserve quantities include: (i) oil and natural gas quantities in excess to cost recovery which the company has an obligation to purchase under certain PSAs with governments or authorities whereby the company serves as producer of reserves. In accordance with SFAS No. 69, paragraph 13, reserve volumes associated with such oil and gas quantities represented 1.4%, 1.7% and 1.1% of total proved reserves as of year-end 2004, 2005 and 2006 respectively, on an oil-equivalent basis; (ii) volumes of natural gas used for own consumption and (iii) volumes of natural gas held in certain Eni storage fields in Italy. Proved reserves attributable to these fields include: (a) the residual natural gas volumes of the reservoirs and (b) 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 sold. 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 judgment. Results of drilling, testing and production after the date of the estimate may require substantial upward or downward revision. In addition, changes in oil and natural gas prices have an effect on the quantities of Eni’s proved reserves since estimates of reserves are based on prices and costs relative to the date when such estimates are made. Reserve estimates are also subject to revision as prices fluctuate due to the cost recovery feature under certain PSAs. The following table presents yearly changes by geographical area in estimated proved reserves, developed and undeveloped, of crude oil (including condensate and natural gas liquids) and natural gas for the years 2004, 2005 and 2006.

(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.
(2) |  | Represents the financial effect of the passage of time relating to Eni’s future asset retirement obligations pursuant to SFAS 143 “Accounting for asset retirement obligations”.

ENI FACT BOOK / SUPPLEMENTAL OIL AND GAS INFORMATION

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 as of December 31, 2004, 2005 and 2006 include amounts that Eni’s Gas & Power segment and other gas companies correspond for storages services, required to support market demand flexibility needs. |  | 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.

ENI IN 2006 / TO OUR SHAREHOLDERS

To our Shareholders

|  | Roberto Poli Chairman |  | Paolo Scaroni CEO

2006 was a remarkable year for Eni in terms of both financial performance and operational accomplishments. Our earnings and cash flow were the highest in our history, driven by continued improvements in performance and consistent execution of our strategy in a broadly favorable trading environment. In particular, we maintained pleasing production growth despite the impact of disruption in Venezuela, achieved several exploration successes, secured access to promising new acreage and further expanded our global natural gas business. On top of that, we struck a landmark agreement with Gazprom which extends our gas contracts to 2035 and opens up new opportunities for upstream expansion in Russia. Financial performance Our reported net profit of euro 9.2 billion in 2006 was the highest in the history of the Company. Adjusted net profit rose 12.5% to euro 10.4 billion, representing a return on average capital employed of 22.7%. Net cash generated by operating activities totalled euro 17 billion, allowing us to finance capital expenditure of euro 7.8 billion and to reduce our debt/equity ratio to 0.16. Those strong results enabled us to propose a dividend of euro 1.25 per share to our Annual General Shareholders’ Meeting, up 14% compared to 2005 (euro 1.10 per share), of which euro 0.60 was paid as an interim dividend in October 2006. During the year, we purchased a total of 53.1 million of our own shares for euro 1.2 billion, bringing the total cash returned to shareholders for the year to euro 5.8 billion. Our total shareholder return was 14.8%, making this the fifth year running that we have outperformed our peer group. |  | Sustaining growth and shareholder return Growth is at the heart of our strategic priorities. A strong pipeline of projects and investment opportunities will enable us to achieve our ambitious short and long-term growth targets. Over the next four years, we will invest euro 44.6 billion in our businesses to ensure our continued growth, also beyond 2010. This investment program, the largest ever in Eni’s history, will be carried out with tight financial discipline. The projected free cash flow in 2010 will allow us to sustain the current flow of dividends in real terms, even with a scenario of 40 $/bl Brent. Among Eni’s business divisions, EXPLORATION & PRODUCTION showed the strongest growth. In 2006, the division’s adjusted net profit increased by 17.7% to euro 7.3 billion. Oil and gas production rose by approximately 2% to 1.77 million boepd. This increase was entirely organic and was achieved despite the negative impact of the unilateral termination of the Dación contract in Venezuela and the adverse entitlement effects in PSAs and buyback contracts due to higher oil prices. Excluding the effect of higher oil prices on PSAs and the termination of the Dación contract, organic production growth was close to an impressive 6%. We are committed to maintaining strong organic production growth. The company targets a production level of 2 million boepd by 2010, with an average growth rate of approximately 3% per year. Exploration activity reaped substantial results in 2006, reaching an average success rate of 49% and adding 152,000 sq km of net acreage, 99% operated. Over the medium term, we are committed

to replacing more than 100% of produced reserves. Development activities are progressing in many fields around the world, including Kashagan, where we expect higher capex and a longer timetable. However, we have also been able to confirm that the field is capable of higher production levels than previously thought. We are progressing with the global expansion of the LNG business as a way to monetize our large gas reserve base. Major steps taken in 2006 include the start-up of train five at the Bonny liquefaction plant in Nigeria, where a sixth train will commence operations in 2008, and the signing of a framework agreement for doubling the capacity of the Damietta liquefaction plant in Egypt by 2010. The growth options we are presently pursuing with our partner Gazprom could potentially enable us to accelerate the achievement of our growth targets. In GAS & POWER, our strong and integrated position in Europe generates stable and robust earnings and cash flows. Adjusted net profit for the year rose by 12.1% to euro 2.9 billion, supported by an approximately 16% increase in volumes sold in Europe (excluding Italy) to 35 bcm (excluding gas sold by E&P of 4 bcm). This result was achieved despite stiff competition and mild weather. Our strategy is based on growing our market share in key European markets, preserving our domestic natural gas business and effectively managing our regulated business. European natural gas demand is forecast to grow steadily in the future, resulting in a cumulative increase of around 45% by 2020 (2.4% per annum). This, coupled with the decline of Europe’s internal production, means that our continent will become more and more reliant on external supplies to fulfill its gas needs. In this context, Eni is poised to further strengthen its market leadership by leveraging on an unparalleled portfolio of assets in terms of infrastructure, availability of gas – both equity and purchased under long term supply contracts – long-standing relationships with natural gas producing countries, market knowledge and a large customer base. The recent alliance with Gazprom marks a new milestone in our relationship with the largest natural gas producer in the world, and will enable us to reinforce our competitive profile. By 2010 we are committed to selling more than |  | 105 bcm of gas worldwide, with sales outside Italy expected to grow at an average rate of 10% per year. Our REFINING & MARKETING division reported an adjusted net profit of euro 629 million, which was 33.4% lower than in 2005 due to the weak refining margin environment, the appreciation of the euro against the dollar and the impact of higher levels of planned maintenance activity. Looking forward, several trends are emerging in the refining landscape: the adoption of increasingly strict environmental standards, global imbalances in product availability (especially a deficit of diesel fuel in Europe), a relative abundance of heavy crude and the desire to increase efficiency. These are the key drivers of our strategy. In Refining, Eni will increase its capital expenditure to enhance the refinery conversion rate in order to meet future product quality requirements, produce higher-value products and chemical feedstocks, lower operating costs and increase refinery flexibility in processing low-quality crude oils. In Marketing, we aim to extract full value from our retail business in Italy through a selective investment program, customer-focused marketing initiatives, effective differentiation of pricing, an improved premium-products offer, and operating efficiencies. In managing our PETROCHEMICAL operations, which reported an adjusted net profit of euro 174 million for 2006, we remain committed to improving efficiency and selectively developing those plants with sufficient scale and a favorable geographic location. Capital expenditure will be focussed on implementing de-bottlenecking projects, enhancing the efficiency and flexibility of plants in areas of excellence (styrenes and elastomers) and maintaining high standards of health, safety, security and environmental performance. In ENGINEERING & CONSTRUCTION, adjusted net profit rose by 22% to euro 400 million, reflecting the strong competitive position held by Saipem, also as a result of the integration of Snamprogetti. To cope with rising demand for drilling equipment and oilfield services, Saipem is planning to further expand the geographical reach and operational features of its world-class fleet. Our relentless commitment to technological research and innovation underscores a fundamental belief that technology is key to increasing our competitive

advantage over the long term and promoting sustainable growth. We are conducting research aimed primarily at reducing the costs of finding and recovering hydrocarbons, upgrading heavy oils, monetizing stranded gas and protecting the environment. In particular we are moving forward on our breakthrough technologies: EST (Eni Slurry Technology) for the full exploitation of the heavy barrel, TAP (gas transportation at high pressure) and GTL (gas-to-liquids) for gas monetization. |  | Sustainable development 2006 marks the first year in which Eni has published a Sustainability Report to communicate more effectively with stakeholders. We now have a more coherent approach to sustainability, and are even more committed to managing and developing your company in a responsible and accountable way. Among the various initiatives, our focus is on reducing greenhouse gas emissions from industrial processes and developing projects to economically exploit flared gas. In conclusion, 2006 was a very good year for Eni. As well as delivering impressive results, we have worked to create future growth opportunities in all our divisions. We are confident that we can continue to deliver industry-leading growth and superior shareholder returns.

Eni’s key objectives are to deliver superior growth and attractive shareholder returns over the long term.
Eni’s strategy is consistent with these goals and is based on the following guidelines:
- leverage on its asset portfolio and execution capabilities;
- allocate the cash generated from operations to capital expenditure, driving long-term organic growth, and to an attractive and sustainable flow of dividends;
- use cash in excess of capital expenditure and dividend needs to continue the programme of share repurchase and to maintain a solid financial structure;
- apply tight financial discipline to investment decisions;
- continue to improve operating efficiency and effectiveness;
- manage risks;
- devote significant resources to technological innovation in order to create and maintain competitive advantages;
- promote the sustainability of the business model.
Over the next four years, Eni will implement the largest capital expenditure program in its history by investing euro 44.6 billion in its businesses to support continued growth, also beyond 2010. The ability to generate robust cash flow from operations will enable Eni to finance its capital expenditure plans and to sustain the distribution of dividends to shareholders.
Since 2000, we have returned approximately euro 27 billion to our shareholders through dividends and repurchase of own shares. Of that, approximately 80% has been distributed to shareholders via dividends, which have been hiked by an impressive 200% over this period. At the same time, we invested approximately euro 66 billion in capital expenditure and acquisitions in order to boost growth in all our businesses, achieving in particular a 50% increase in daily oil and gas production (or a compound annual growth rate of approximately 7%). Meanwhile, we have managed to maintain a healthy balance sheet thanks to our impressive cash flow generation, totaling euro 85 billion; a further euro 7 billion was generated by divesting non strategic assets and businesses. Finally, thanks to the repurchase of our own shares, we have reduced the number of shares outstanding by approximately 8%, boosting earnings per share by the same amount.

STRATEGIES
In Exploration & Production, Eni boasts strong positions in some of the fastest growing oil and gas basins in the world such
as the Caspian Region, North and West Africa. The quality of our assets, long-standing relationships with key host countries,
and a strong pipeline of capital projects and investment opportunities will enable Eni to deliver industry-leading growth in both the short and the long term. Consistent with this goal, strategies for our global exploration, development and production operations have remained basically unchanged for many years to date and feature as follows:

Maintain strong production growth; Ensure medium to long-term business sustainability by focusing on reserve replacement; Develop new projects to fuel future growth; and Develop the LNG business. In order to carry out these fundamental strategies, Eni intends to invest approximately euro 30.6 billion addressed to exploration initiatives and reserve development over the next four-year period frame. 2006 HIGHLIGHTS In February 2007, Eni purchased exploration and production onshore activities operated by Maurel & Prom in Congo, entailing a cash consideration of $1.4 billion. This deal is consistent with Eni’s strategy of purchasing proved and unproved reserves and producing assets in legacy countries where Eni can achieve synergies leveraging on own competencies and the availability of facilities. This transaction is subject to approval by the Congolese authorities. In 2006 adjusted net profit was euro 7,279 million, up euro 1,093 million from a year ago (+17.7%), reflecting a better operating profit as a result of higher oil and natural gas realization in dollars combined with increased production volumes sold. These positives were offset in part by higher operating costs and a high adjusted tax rate. Return on average capital employed calculated on an adjusted basis was 37.5% in 2006, higher than in 2005 (32.4%). Oil and natural gas production for the year averaged 1.77 mmboe/d, up 1.9% from 2005. This included the loss of production at the Venezuelan Dación oilfield and lower entitlements in certain Production Sharing Agreements (PSAs) and buy-back contracts due to higher oil and gas prices. Eni delivered its 3% production growth rate based on a $55 per barrel scenario, as announced in the 2006 quarterly production outlook. |  | Net proved reserves at December 31, 2006 stood at 6.44 bboe (down 6% compared with December 31, 2005), representing 10 years of remaining production at the current rate. Organic proved additions, as calculated by applying a year-end Brent price of $58.925 per barrel, replaced 65% of production. Assuming Brent is constant at $40 per barrel when determining entitlements in PSAs, the three-year average proved reserve replacement ratio would be 106%. Eni invested euro 3.6 billion in the development of oil and natural gas reserves, in particular in Kazakhstan, Angola, Egypt and Italy. In exploration activities Eni invested euro 1.4 billion (up 106% compared with 2005) to support reserve replacement and the renewal of its portfolio. In 2006, Eni achieved several hydrocarbon discoveries, mainly in Indonesia, Egypt, Kazakhstan, Norway, Nigeria, the United Kingdom, the Gulf of Mexico, Italy, Angola and Congo. A total of 68 exploratory wells were completed (35.9 net to Eni), with a commercial rate of success of 43% (49% net to Eni). A further 26 wells were in progress as of the year-end. Eni’s exploratory portfolio was strengthened through acquisition of assets in both core areas such as Angola, Alaska, Brazil, Congo, Egypt, Nigeria, Norway, Pakistan, the Gulf of Mexico and new countries/areas with high mineral potential such as Mali, Mozambique and East Timor. Gross acquired acreage extends for approximately 259,000 square kilometers (152,000 net to Eni, 99% operated).

> > > Algeria, the principal producing fields operated by Eni are located in the Bir Rebaa area in the South-Eastern desert.

Maintain strong production growth Eni’s strategy is to build on its strong position in some of the world’s most attractive oil and gas basins to deliver industry leading production growth. We plan to accomplish this by applying the most cost-effective technologies and operations management systems to each and every asset to maximize the commercial recovery of hydrocarbons. Eni’s assets are well balanced between mature producing fields and fields that are at the early stages of their producing cycles with significant opportunities for growth. Mature areas include mainland and offshore Italy, the North Sea and certain basins in Egypt. Growing areas include Libya, offshore and onshore West Africa, the Caspian Sea and the Nile Delta. Eni expects contributions from the latter to boost production growth to 2010 and beyond. |  | Eni continually invests in its existing asset base to increase resource recovery, maximize profitability, and extend field life. New production volumes are generated through workovers, drilling of new wells, and projectimplementation. In 2006, Eni invested euro 3.6 billion to develop new reserves and to maximize resource recovery from existing fields. In the next four years, Eni plans to invest approximately euro 22.5 billion evenly allocatedto initiatives intended to counteract mature field decline, fuel medium-term growth and support growth beyond 2010. Several fields/projects were started up during 2006. Among the key start-ups are: (i) the Benguela/Belize and Lobito/Tomboco fields in Block 14 (Eni’s interest 20%), holding recoverable reserves of approximately 460 mmbbl. Peak production at 158 kbbl/d (20 net to Eni) is expected in 2009 upon completion of the drilling

program; (ii) the fifth train as a part of the development of the Bonny liquefaction plant (Eni’s interest 10.4%) in Nigeria, increasing plant capacity to 17 mmtonnes/y of LNG (812 bcf/y of feed gas); (iii) the gas phase of the Bayu-Undan field (Eni’s interest 12.04%) in Australia, starting supplies to the Darwin plant with liquefaction capacity of 3.5 mmtonnes/y of LNG. Peak production at 160 kboe/d (18 net to Eni) is expected in 2008. PRODUCTION VOLUMES OUTLOOK In 2006, oil and gas production averaged 1,770 kboe/d, up 33 kboe from 2005 or 1.9%, despite; (i) the impact of the loss of production at the Dación oil field in Venezuela (down 46 kboe/d) as a consequence of the unilateral cancellation of the relevant service contract by the Venezuelan state oil company PDVSA; and (ii) adverse entitlement effects (down 21 kboe/d) in PSAs and buy-back contracts due to higher oil prices. Production growth was driven by a remarkable increase in gas production mainly in Libya, Egypt, Nigeria, Australia and Croatia; oil production increased in Angola and Libya. Organic growth was partially offset by mature field |  | declines and production outages in Nigeria due to social unrest. The share of production outside Italy was 87% (85% in 2005). In the medium term, Eni expects to deliver a 3% compound average growth rate from 2007 to 2010, targeting a production level in excess of 2 mmboe/d by 2010. In subsequent years and up to 2013, Eni projects an annual growth rate of 3%. This goal will be achieved entirely through organic growth mainly in our key producing basins of North and West Africa and the Caspian region, leveraging on Eni’s unique position and solid relationships with many of the fastest growing producing countries in the world and on its strong pipeline of capital projects and investment opportunities. In greater detail, production growth will be fed by means of: developing LNG projects, aiming at monetizing our large gas reserve base; starting up new fields, some of which already under execution and other waiting for finalization of exploratory and appraisal activities; leveraging on our long life fields, including Karachaganak in Kazakhstan, the Western Libyan Gas project, Val d’Agri in Italy, Ekofisk and Aasgard offshore Norway, Belayim and Port Fouad in Egypt, and, in perspective, our massive Kashagan field; optimizing reserve recovery from declining fields. Eni’s future production profiles are based on a long-term Brent price assumption of 40 $/bbl in real terms. Actual production volumes will vary from year to year due to the timing of individual project start-ups, operational outages, reservoir performance, regulatory changes, asset sales, severe weather events, price effects under production sharing contracts, and other factors.

> Val d’Agri field Southern Italy. Producing since 1999, Val d’Agri exemplifies a long-life field within Eni’s asset portfolio. In 2006 this field produced 82 kboe/d net to Eni on average, and is expected to deliver a solid production plateau over the next several years thanks to continued development.

ENI IN 2006 / EXPLORATION & PRODUCTION

Ensure medium to long-term business sustainability by focusing on reserve replacement Eni intends to pay special attention to reserve replacement in order to ensure the medium to long-term sustainability of its business. In pursuing this goal, Eni intends to: optimize its portfolio of development properties by focusing on core areas, seeking new opportunities and divesting marginal assets; pursue new exploration opportunities targeting a sound balance between high risk/high reward initiatives and established/mature projects. As of December 31, 2006, Eni’s portfolio of mineral rights consisted of 1,029 exclusive or shared rights for exploration and development in 36 countries on five continents for a total net acreage of 385,219 square kilometers. Of these, 48,273 square kilometers concerned production and development. This geographically and geologically diverse, high-quality portfolio balances risks and rewards to deliver both near-term and long-term production growth. In the medium term, Eni expects to more than replace produced reserves through organic additions. Eni’s reserve replacement ratio will be supported by the high mineral potential of our assets located in core areas such as the Caspian Sea, West and North Africa. |  | GROWING THE RESOURCE BASE The success of Eni’s approach is demonstrated by its ability in replacing produced reserves. Between 2003 and 2006, exploration reserves discovered were approximately 700 mmboe on average a year for a cumulative amount of 2.8 bboe, higher than our cumulative production over the same period. Positive contributions came from both legacy countries such as Nigeria, Angola, Egypt and Kazakhstan and new frontier areas such as the Barents Sea and the ultra-deep waters of the Gulf of Mexico. At 25 bboe, our solid resource base will secure 38 years of production at current rates. Under SEC reporting standards, proved reserves at 2006 year-end were 6.4 billion boe, representing a life index of 10 years. In the 2004-2006 period, considering adverse entitlement impacts in certain PSAs and buy-back contracts resulting from higher oil prices and assuming Brent constant at $40 per barrel when determining entitlements in PSAs, we would have replaced on average 106% of production through organic additions. On the other hand, contractual terms of PSAs providing for a cost oil with a favorable cap, while affecting the reported reserve replacement ratio, allow a strong acceleration of investment recovery under a higher price environment, thus enabling a reduction in payout time and a significant improvement in the rate of return of relevant projects. For 2006 only, by applying the year-end price of 58.925 $/bbl, organic additions for the year came in at 417 mmboe with a reserve replacement ratio of 65%.

EXPLORATION OPPORTUNITIES Exploration activities will play a crucial role in enlarging Eni’s resource base in order to fuel new production, and in securing access to new opportunities. In light of this, management will devote a great deal of focus and effort to exploration. In 2006, Eni more than doubled its investment in exploration from the previous year, resulting in a total of 68 wells drilled with an SEC exploration success of 43%, and approximately 152,000 square kilometers of new acreage acquired. In the next four years, management plans to invest on average approximately euro 1.1 billion per year in exploration activities, resulting in a cumulative euro 4.4 billion that is substantially higher (+51%) than the previous four-year plan (2006-2009). The cornerstones of Eni’s exploration strategy are: selectively assess opportunities to enhance the competitiveness of Eni’s full-cycle production costs; concentrate resources in core areas: approximately 70% of planned investment will be directed to 10 countries; exploit the full mineral potential of recently acquired areas; complete portfolio renewal. In 2006, as part of its exploration strategy, Eni was successful in capturing 12 new opportunities spanning from new, untested exploration plays to well established plays or already-discovered resources, for a total acreage of about 152,000 square kilometers net to Eni, of these 99% as operator. In fact, management intends to concentrate investments in well established areas of presence where availability of production facilities, |  | existing competencies and long-term relationships with host countries will enable Eni to readily put in production discovered resources, reducing the time to market and capturing synergies. On the other hand, Eni expects to selectively pursue high risk/high reward opportunities arising from expansion in areas with high mineral potential. Finally, portfolio renewal will be completed, bearing in mind that approximately 70% of total acreage has been renewed over the last three years.

Developing new projects to fuel future growth Eni has a strong pipeline of development projects that will contribute to the medium and long-term growth of its oil and gas production. Approximately 20 of these projects are among the top 100 projects worldwide. Eni expects an evolution in the type of oil and gas resources from which it will be producing and in the physical conditions in which it will be operating. Many new developments will be located in more challenging |  | environments, continuing to require innovations in technology. Our new long life projects, integrated LNG projects and new start ups will boost Eni production growth over the medium and long term. Overall, start ups expected in future years will add approximately 450 kboe/d to 2010 production and 700 kboe/d to 2013 production. New production will come from both legacy countries and new regions as well as from mature basins and new high potential ones.

ENI IN 2006 / EXPLORATION & PRODUCTION

Karachaganak - Kazakhstan (Eni 32.5% Co-op.) This large liquid and gas field located onshore Kazakhstan holds recoverable reserves of 3.6 bboe. It represents an example of a long life field. Liquid production is treated at the Karachaganak Processing Complex with a capacity of 150 kboe/d. Two-thirds of liquid volumes are exported to western markets via pipeline; residual liquid and gas volumes are sold on local Russian markets. In 2006, production of this field net to Eni was 103 kboe/d. Development activities planned aim at maintaining current liquid production plateau. In 2006 upgrading of liquid treatment facilities was sanctioned envisaging the construction of a fourth unit. Such new capacity is expected to increase the export of production volumes which were previously marketed on local Russian markets, resulting in an enhancement of price realizations. In addition, management is evaluating the development of gas reserves by means of finalizing relevant sale contracts with Kazakh and Russian companies, also entailing, if contracts are finalized, the construction of a gas treatment plant. Kashagan - Kazakhstan (Eni 18.5% Op.) The development plan of the massive Kashagan oil field, considered the most important discovery of the past thirty years, to be implemented in three phases, aims at producing up to 13 billion barrels of recoverable reserves also by means of partial gas reinjection. The development of the field provides for 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 Bolashak, 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. Production start-up is currently scheduled for the third quarter of 2010 as compared to an initial forecast indicating a start-up in 2008, due also to the need on part of Eni to perform certain studies to define measures intended to enhance the overall level of safety and operability of facilities. As a result of said reconfiguration completed by year-end, the onshore design has been confirmed, while certain enhancements have been identified offshore which do not alter the original development concept. These enhancements are expected to be included in the development plan and implemented. Estimated capital expenditure to reach the 300 kbbl/d production level targeted in the first development phase stands currently at $19 billion, representing a remarkable increase over the approved budget of $10.3 billion in real terms 2007, sanctioned in 2004. This cost increase was driven by: (i) a cost increase of materials and services driven by sector-specific inflation and a negative impact due to a weakening US dollar; (ii) an underestimation of costs to conduct offshore operations in shallow/ultra shallow waters where the Kashagan field is located due to a lack of benchmarks, also reflecting technical and logistic issues and environmental constraints; (iii) the enhancements to the original layout of offshore facilities. Based on the high level of productivity yielded by the first three development wells, management currently expects a full field production plateau of 1.5 mmboe/d, representing a 25% increase from the original target envisaged by the development plan. In addition, over

the long term management expects to exploit the huge mineral potential of Kashagan satellite discoveries, including Kalamkas and Kairan, which are currently undergoing an intense appraisal campaign. To date this campaign has resulted in a 100% success rate, fostering high expectations on future developments of Kashagan satellites. The Consortium is currently assessing various options to export production to international markets, including: (i) use of existing infrastructure, such as the Caspian Pipeline Consortium pipeline and the Atyrau-Samara pipeline; and (ii) construction of new infrastructure. The latter comprises both laying a pipeline connecting the Kashagan production center at Bolashak to the Baku-Tbilisi-Cehyan pipeline (BTC-Eni’s interest 5%, corresponding to the right to transport up to 50 kbbl/d), and construction of a pipeline designed to bypass the Turkish Straits of Bosphorus and Dardanelles, enabling delivery of oil produced in the Caspian region to the Ceyhan commercial hub on the Mediterranean coast. |  | This new infrastructure is expected to be 550-kilometers long with a maximum transport capacity of 1.5 mmbbl/d of oil, corresponding to approximately 75 mmtonnes/y, and will represent a more efficient and environment-friendly alternative compared to the option of transporting oil by ship through the Turkish Straits of Bosphorus and Dardanelles. Following award of the relevant license to the Turkish company Çalik Enerji, partnering Eni in this initiative (both with a 50% stake), engineering activities started in the second half of 2006. Taurt - Egypt (Eni 50%) The offshore Taurt gas field contains gross recoverable reserves of 930 bcf and is located in the Nile Delta at a water depth of 105 meters. The development plan provides for the drilling of seven wells which are expected to be linked to existing onshore treatment facilities at West Harbour. Production plateau is targeted at 46 mmcf/d net to Eni, in 2008.

ENI IN 2006 / GAS & POWER

In 2006 the Gas & Power business confirmed its ability to generate strong and stable performances. The adjusted net profit rose by euro 310 million to euro 2,862 million from 2005 (up 12.1%) reflecting primarily higher selling margins on natural gas sales, a lower impact of sector specific regulation, and a growth in gas volumes sold. Operating cash flow stood at euro 3.1 billion, resulting in euro 1.9 billion of free cash flow generation after taking account of capital expenditure requirements and changes in working capital. Natural gas sales were up approximately 4% to 97.48 bcm driven primarily by a 16% growth in sales in a number of target European markets (mainly in Turkey, Germany/Austria, France) owing also to a build-up of supplies of natural gas from Libya. Volumes decreased in Italy due to mild weather conditions in the fourth quarter of the year. Electricity production sold was 24.82 TWh, up 9%; installed capacity totalled 4.6 GW at year-end. Clients served increased by approximately 0.52 million to 6.54 million. |  | Capital expenditure totalled euro 1,174 million and related essentially to development and maintenance of Eni’s transport and distribution networks in Italy, the finalization of the upgrading plan of electricity generation capacity, and the start up of the upgrading plan of import gaslines. Return on average capital employed was 15.1% in 2006 (13.7% in 2005). Marketing of natural gas MARKET POSITION Eni is leader in the highly attractive European gas sales market, with a market share of around 18% in 2006. Since the inception of the domestic liberalization process in 2000, Eni has targeted several European consumption areas to pursue growth options beyond its legacy Italian market. This strategy is paying off. Presently, Eni boasts a solid presence in virtually all European markets, including Spain, Germany, Turkey, the United Kingdom, France and Portugal, and is poised to further strengthen its market leadership. In fact, with European natural gas demand forecast to grow steadily in the future, resulting in a cumulative increase of around 45% by 2020 (or 2.4% per annum), and internal production on a declining trend, Europe will increasingly rely upon gas imports to fulfill its gas needs. In such a context, Eni is expected to grow its market share and sales leveraging on its strong competitive position and an unparalleled array of assets in terms of gas availability of both equity gas and purchased gas under long term supply contracts with key producing countries, operating flexibility ensured by an extensive and integrated international transport network, regasification terminals, storage facilities, a large client base, and market knowledge. The recently signed deal with strategic partner Gazprom markedly improves Eni’s competitive profile.

In the medium term, Eni plans to increase worldwide sales targeting a volume of 105 bcm by 2010, corresponding to a 2.5% average growth rate over the 2007-2010 four-year period. This increase will be driven by an expected 10% average organic growth rate in sales in the rest of Europe to 53.3 bcm. In Italy, Eni expects to sell approximately 50 bcm by 2010, or 46% of the total. In particular, Eni expects to boost sales in target European markets, leveraging mainly on sale expansion in: Northern Europe, where Eni forecasts an increase of approximately 5.4 bcm reflecting in particular a growth in supplies to spot markets; |  | France, where Eni forecasts an increase of approximately 4 bcm reflecting an aggressive policy of building market share, targeting mainly small and mediumsized industrial enterprises; the Iberian Peninsula, where Eni forecasts an increase of approximately 3.3 bcm as a result of expected higher supplies to power generation utilities and a growth of Eni’s strategic affiliate Unión Fenosa Gas; Austria/Germany, where Eni forecasts an increase of approximately 2.9 bcm reflecting a growth in business clients; and Turkey, where Eni forecasts an increase of approximately 2.7 bcm owing to the build-up of supplies via the Blue Stream gasline.

Supply of gas In the context of rising gas demand and increasingly tight European markets, Eni enjoys a very strong position owing to an unrivaled supply portfolio and access to a wide-reaching infrastructure network. Our availability of natural gas is ensured from both equity production from onshore and offshore fields located in Europe (mainland and offshore Italy, the North Sea and offshore Croatia) or in adjacent basins (Libya via gasline and Egypt/Nigeria via LNG), and long term purchase contracts with major producing countries serving Europe, boasting a direct upstream presence in 8 out of 10 of our gas supplying countries. Our diversified supply portfolio insulates us from the |  | risk of being heavily dependent on a single source of supplies; in fact, none of Eni’s suppliers weighs for more than 25% in Eni’s current gas needs. In addition, our strong pipeline of LNG projects will further strengthen diversification of Eni’s supplies and integration with upstream operations. Against this backdrop, the recently signed agreement with strategic partner Gazprom marks a fundamental step in enhancing the security and flexibility of Eni’s gas supplies over the medium and long term. Based on this agreement, the duration of our long-term supply contracts increases from 14 to approximately 23 years and, when these contracts are fully operational in 2010, Eni will be able to purchase approximately 62.4 bcm/y to cope with rising demand.

Infrastructure Eni owns the largest European transport and storage infrastructure system, enabling Eni to carry gas from producing countries or its upstream fields to core European markets. Vital to this system are: interests in key pan-European routes carrying natural gas from the production areas of the North Sea and Russia to large Central European markets, as well as in trunklines coming from Algeria and Libyan operated fields. Such lines are linked to the Italian network; an extensive grid of high and medium-pressure trunklines and low-pressure local networks for transport and delivery of gas in its core domestic market to large industrial clients, power generation utilities, and residential and commercial clients; |  | interests in certain facilities for the regasification of liquefied natural gas (LNG) located in Italy and Spain to further diversify sources of supplies; availability of a significant storage capacity ensuring the necessary operational flexibility. In the medium term, Eni plans to invest approximately euro 5.8 billion in order to upgrade both its international and national infrastructure, in view to improve the level of supply diversification and security also to cope with expected growth in demand. A major part of this capital expenditure will be directed to the upgrading of import trunklines from Russia, Algeria and Libya, the national transport and distribution networks, and regasification capacity.

INTERNATIONAL TRANSPORT Eni’s INTERNATIONAL TRANSPORT system consists of transport rights on an approximately 4,300-kilometer long network of high pressure pipes connecting production areas in Russia, North and West Africa, and the North Sea to Italy, crossing key European markets. Through its 50%-owned Blue Stream, a 774-kilometer long underwater gasline, Eni is able to supply the fast-growing Turkish market. Eni’s international transport network will undergo a major upgrading plan in order to boost transport capacity of trunklines carrying gas from Algeria, Russia, and Libya; in particular: |  | TTPC - The transport capacity of the TTPC gasline from Algeria is expected to be increased by 6.5 bcm/y of which a 3.2 bcm/y portion is planned to come on line on April 1, 2008, and a 3.3 bcm/y portion on October 1, 2008. Capital expenditure is expected at euro 450 million. When the upgrade is fully operational, the gasline will deploy a transport capacity of 33.5 bcm/y. A corresponding capacity on the TMPC downstream gasline is already available. TMPC crosses underwater the Sicily channel.

TAG - The transport capacity of the TAG gasline from Russia is expected to increase by 6.5 bcm/y coming on line on October 1, 2008. Expected capital expenditure amounts to euro 253 million (Eni’s share is 94%). When the upgrade is online, the gasline transport capacity will be 44 bcm/y. GreenStream - Eni plans to upgrade this import gasline from Libya in order to monetize additional reserves of gas. This project targets a 3 bcm/y capacity expansion |  | expected to come on line by 2011, with an expenditure of approximately euro 80 million. Taking into account the full capacity of the GreenStream gasline from Libya currently in place (8 bcm/y), Eni expects to bring on the market approximately 21 bcm/y of new import capacity, when ongoing plans for upgrading the TTPC and TAG gaslines are fully operational in 2009. This new capacity has been or is being allocated to third parties via open bid procedures.

> Turkey; the Blue Stream underwater pipeline, laid at a record depth of over 2,150 meters, links the Russian and Turkish coast of the Black Sea. Started up in 2002, this two-line infrastructure has a transport capacity of 49 mmcm/d. When fully operational in 2010, it will deliver 16 bcm/y (Eni’s share 8 bcm) to the Turkish market.

DOMESTIC TRANSPORT AND DISTRIBUTION Eni’s DOMESTIC TRANSPORT business is a fully regulated activity with a low risk profile, generating stable earnings and operating cash flow. In fact, transport tariffs and return on capital employed are set by an independent regulator. Eni’s network extends for 30,889 kilometers covering virtually the entire Italian transport network and comprises high pressure trunklines and medium pressure regional transport networks carrying natural gas from entry points to the system – import lines, storage sites and Italian natural gas fields – to delivery points in correspondence of large industrial complexes, power generation utilities, and local distribution companies serving residential and commercial areas. In the medium term, Eni plans to upgrade its domestic transport network in order to match transport capacity to the expected increase in import capacity. Due to regulatory mechanisms, these capital projects bear preset rate of returns, thus contributing to reduce the risk profile of Eni’s capital expenditure plan. We also plan to boost earnings of this regulated activity by continued efforts in improving operational efficiency. |  | Eni is leader in the Italian natural gas distribution business, counting on the availability of an extensive grid of low pressure gaslines for the delivery of natural gas to approximately 6 million clients in the main urban areas of Italy. Clients include both residential users and small businesses and commercial clients. In the distribution business, Eni will focus on improving efficiency and reaping economies of scale, while at the same time enhancing the quality of service. As in the case of the transport activity, distribution is a fully regulated business sporting a preset return on capital employed. LNG Eni intends to strengthen its integrated LNG business on a global scale, aiming at further diversifying its supply sources, improving operational flexibility, and monetizing its large equity gas reserves. Due to our strong presence in both upstream and downstream operations, we boast a global position in LNG which is well balanced in terms of gas availability, and both liquefaction and regasification capacity. We expect LNG to play an increasingly important role

in fulfilling worldwide gas requirements, with forecast growth rates in the range of 10% over the medium term. Eni’s main LNG assets are located in: Italy, where the Panigaglia regasification terminal can input approximately 3.5 bcm/y in the national transport network; Egypt, where Eni has a 40% interest in the Damietta liquefaction plant producing approximately 5 mmtonnes/y of LNG, corresponding to 7.6 bcm/y of feed gas. In June 2006, Eni and its partners signed a framework agreement for doubling the capacity of the plant expected to start operations in 2010-2011; |  | Spain, where Eni has a 21.25% interest in the Sagunto plant with a regasification capacity of 6.7 bcm/y and a 9.5% interest in the El Ferrol plant, expected to be completed by the first half of 2007, targeting a regasification capacity of approximately 3.6 bcm/y; USA, where Eni is entitled to a 6 bcm/y share of the initial planned capacity of the Cameron regasification terminal under construction in Louisiana, and expected to start operations in 2008-2009. In order to support supplies to this plant, Eni signed an agreement with Nigeria LNG Limited, operating the Bonny LNG plant in Nigeria, to purchase volumes of LNG equivalent to 2 bcm/y of gas for a twenty-year period. A similar agreement pertaining to 2.3 bcm/y was signed with Brass LNG equivalent, operating a liquefaction terminal under construction in Nigeria.

Power generation Eni’s natural gas business is integrated downstream with the production of electricity to further extract value from the gas chain. Started in 2000, Eni’s plan for the expansion of its power generation capacity has been substantially completed by the end of 2006, with approximately 90% of the 5.5 gigawatt target new capacity already on stream. New plants built in existing Eni sites are based on cogeneration, an efficient, environmental-friendly technology that enables low operating costs and lower carbondioxide emissions as compared to other hydrocarbon-based technologies. In 2006, electricity production sold was 24.82 TWh, up 9% over 2005, reflecting the ramp-up of new capacity. In 2010, when target capacity is fully on line, production is expected to reach 30 TWh, corresponding to over 10% of electricity generated in Italy at that date, consuming approximately 6 bcm/year of gas from Eni’s supply portfolio. |  | Ravenna in Northern Italy.

ENI IN 2006 / REFINING & MARKETING

STRATEGIES
Eni is leader in the refining business and in the marketing of refined products in Italy and holds solid positions in the marketing of refined products in selected European countries. Eni’s refining and marketing operations are efficiently integrated to maximize cost efficiencies and deliver appreciable returns on capital employed. The integration of Eni refineries with upstream operations further strengthens the competitive positioning of the Refining & Marketing Division.
Eni’s key medium term objective in its downstream oil business is to improve profitability. The strategic guidelines to attain this objective are the following:

- Enhance Eni’s refining system by means of a focused investment programme;

- Improve profitability and qualitative standards of the Italian retail network;

- Grow retail sales in selected markets in the rest of Europe; and

- Pursue higher levels of operational efficiency.

In the medium term the implementation of these strategies will be supported by a capital expenditure programme of approximately euro 4.3 billion, focused on upgrading refineries, mainly by increasing primary balanced refining and conversion capacity, and refineries’ flexibility and efficiency, improving logistic assets, and highgrading the network. Management intends to strengthen market leadership in refining in the Mediterranean area, targeting also leadership positions in Europe, and to boost the competitive position of marketing in Italy and in selected European areas.

2006 HIGHLIGHTS In 2006, adjusted net profit was down euro 316 million to euro 629 million, or 33.4%, mainly due to a decline in refining margins as a result of a weak trading environment. Eni’s realized refining margins recorded a better trend than market reference margins reflecting Eni’s refinery capacity to process heavy crudes which are discounted as compared to the Brent crude market benchmark, thus resulting in a higher profitability of the heavy barrel. Return on average capital employed was 10.7% on an adjusted basis, declining from 2005 (18.2% in 2005). Capital expenditure totaled euro 645 million and mainly related to projects aimed at improving flexibility and yields of refineries and upgrading the retail network in Italy and in the rest of Europe. Refining throughputs on own account in Italy and outside Italy (38.04 mmtonnes) declined by 0.75 mmtonnes from 2005, down 1.9%, due mainly to lower volumes at third party refineries, while wholly-owned refineries achieved stable processing levels. |  |

ENI IN 2006 / REFINING & MARKETING

Retail sales of refined products in Italy (8.66 mmtonnes) declined 1% from 2005 mainly due to competitive pressure. This decrease was more than offset by a growth in retail volumes marketed in the rest of Europe (3.82 mmtonnes, up 4.1%), mainly in Germany and Spain. Sales on the wholesale market in Italy (10.06 mmtonnes) were down 4% reflecting primarily the impact of mild weather conditions in the fourth quarter. This decline was partially offset by a growth in volumes marketed on wholesale markets in the rest of Europe (4.6 mmtonnes, up 2.2%), in particular in Germany and Spain. Refining Eni is leader in the refining business in Italy. Eni owns five refineries in Italy and a 50% interest in the Milazzo refinery, in Sicily, and interests in refineries in Germany and the Czech Republic with a total refining capacity (balanced with conversion capacity1) of approximately 35.5 mmtonnes (equal to 710 bbl/day). In 2006, refining throughputs on own account in Italy and outside Italy were 38.04 mmtonnes, down 0.75 mmtonnes from 2005, or 1.9% due mainly to lower throughputs at third parties refineries. Refining throughputs at own refineries were stable. In particular, refining throughputs increased at the Venice, Gela and Taranto refineries and decreased at the Sannazzaro, and Livorno refineries due to maintenance activity. In April, a new unit for heavy residue gasification started operating at the Sannazzaro refinery. Total throughputs on wholly-owned refineries (27.17 mmtonnes) decreased 0.17 mmtonnes from 2005, down 0.6%; balanced capacity of refineries was fully utilized. Thanks to the continuous upgrading of its manufacturing process, Eni’s refining system can boast a high level of efficiency, flexibility and product quality. At 57%, the conversion index2 of Eni’s refineries compares well with an European average of approximately 33% and enables Eni to extract value from heavy sour grades of the crude feedstock (around 60% of our processed volumes in 2006) which can be purchased with a discount over light/sweet quality crudes like Brent. High levels of conversion capacity and flexibility enable Eni to: promptly respond to a market characterized by extreme volatility of demand and by rapidly shifting demand-supply imbalances among geographic areas; rigorously respect environmental regulations; steadily improve margins as a result of cost reductions and increasing yields of high-value products. |  | The Sannazzaro refinery (Northern Italy).

In the medium term, Eni expects certain trends in demand and supply to shape refiners’ investment decisions and strategies, namely the adoption of increasingly strict environmental standards, global imbalances in product availability (especially a deficit of diesel fuel in Europe), a relative abundance of heavy crude and a striving to increase efficiency. Against this backdrop, Eni plans to boost the profitability of its refining business, capturing market opportunities by means of a focused investment programme, entailing an expenditure of approximately euro 3 billion over the next four years. Main capital projects will be directed to: (i) increase primary and conversion capacity, targeting a complexity index higher than 57%, in view of boosting middle distillate yields, including petrochemical feedstock, and extracting value from equity crude, the availability of which is expected to increase in the Mediterranean basin over the medium term; (ii) improve refinery flexibility in order to optimize processed feedstock and capture market opportunities arising from an expected increasing availability of heavy/sour crude; (iii) achieve high-quality products responsive to expected demand trends and the evolution of product specifications provided for by increasingly tight European standards in term of emissions and environmental preservation; and (iv) enhance operational efficiency of refineries, targeting in particular a higher level of energy efficiency. |  | Key projects of refining upgrading Eni’s plans to revamp its refining system are expected to improve the overall quality of all its assets. In particular, key projects will be implemented at Eni’s largest refineries of Sannazzaro and Taranto. SANNAZZARO - A medium-term high-grading plan for this asset envisages the construction of a new hydrocracking unit and a new deasphalting unit in order to improve operational flexibility, yields of valuable products, and refinery economics. Expected start-up of these new facilities is by end 2008. Conversion capacity is targeted to increase significantly (from the current 46.2% to a planned 63%), resulting in the production of an additional 1 mmtonnes/y of high-quality middle distillates, mainly diesel fuel and jet-fuel. This refinery is already one of the most efficient in Europe thanks to its conversion facilities – including a fluid catalytic cracker, an HDCK middle distillate conversion unit and a visbreaking thermal conversion unit, as well as certain desulphurization facilities – enabling the processing of a wide range of crudes from Russia, Africa and Asia, including the Caspian Sea area. This refinery is also integrated with the production of electricity by means of its gasification unit producing syngas to be used as feed gas for the nearby Eni power station at Ferrera Erbognone.

TARANTO - A medium-term high-grading plan for this asset envisages: construction of a new high pressure hydrocracking unit, targeting production of additional 0.6 mmtonnes/y of high quality diesel oil. Start-up is planned in 2008; construction of a new topping unit, targeting additional process capacity in the range of 4 mmtonnes/y. This plant will be supported by new vacuum and desulphurization facilities to improve yields of middle distillates, and the construction of logistic assets to transport virgin naphtha to Eni’s petrochemical plant in Brindisi, and to market fuels by means of a new storage centre and related pipelines. Eni aims at enlarging consumption areas served by this refinery, covering also the Campania Region as to eliminate supply of refined products to Naples by sea. Start-up is expected in 2009-2010. With a current conversion rate of 61.1%, Taranto is one of the top performers among Eni’s refineries thanks in particular to the availability of a two-stage thermal conversion plant (visbreaking/thermal cracking) and an RHU conversion plant allowing conversion of high sulphur content residues into valuable fuels and feedstock for Eni’s petrochemical plants. It processes most of the oil produced in Eni’s Val d’Agri fields carried to Taranto through the Monte Alpi pipeline. Operational efficiency and environmental performance Eni has always pursued high levels of operational efficiency and environmental performance. Energy consumption of our refineries has shown a steadily decreasing trend for many years to date. In particular, in the 2003-2006 period, we implemented energy saving |  | projects enabling us to reduce energy consumption by approximately 90 ktoe/y when fully operational, resulting in a cut in carbon-dioxide emissions in the range of 270 ktonnes/y. Supplies of electricity and steam to Eni’s refineries come from Eni’s power generation plants using highly efficient, combined cycle gas fired technologies, thus further strengthening Group synergies and reducing carbon-dioxide emissions. A strong focus is also dedicated to adopting the best practices and the highest standards of environmental protection and in pursuing an eco-friendly relationship with the territory as witnessed by the large amount of resources allocated to this issue (on average approximately 22% of capital expenditure of the R&M division over the last three years). Eni can count on a valuable array of logistic assets contributing to the efficiency of its downstream operations.

An example of this approach is represented by the Refinars Project at the Sannazzaro Refinery, where the adoption of avant-garde technology for the de-sulfuring of the combustion fumes from the fluid catalytic cracking process has resulted in emission levels well below the standards provided for by applicable regulations. Eni’s refineries in Italy have production systems fully compliant with standards provided for by the ISO 14001 International Certification; the Taranto, Venice, and Livorno refineries are also compliant with the stricter Environmental Management & Audit Scheme (EMAS) requirements recognized by the European Union. Logistics Eni is leader in the activities of storage and transport of petroleum products in Italy. Our logistical integrated infrastructure contributes in a significant way to an efficient management of downstream operations, ensuring a cost-effective product handling from our refineries to our commercial businesses, including marketing, wholesale, aviation and marine. Eni’s logistic operations are supported by 12 directly managed storage sites, a network of pipelines extending over 3,210 kilometers, and a fleet of tanker trucks. In the medium-term, Eni plans to upgrade its logistic system in line with a planned upgrade of refineries, and to further improve efficiency by implementing an integrated logistic platform according to a “hub” model, designed to centralize handling of product flows, further supporting the efficient integration of refinery and marketing operations. |  | Marketing Eni is leader in the marketing of refined products in Italy and boasts important market shares in selected European areas where it can be supported by Italian production facilities and logistic infrastructure so as to maximize synergies. Popular in the Italian market, the Agip brand is well established in Europe and acknowledged by customers as a guarantee of service and quality. Eni’s strategy in marketing is focused on extracting full value from its network by means of a selected investment programme and efficiency improvement actions. In particular, management intends to: broaden the offer of non oil products, increasing the number of service stations with non oil activities from the current 55% to 80% by 2010; enhance brand loyalty by means of promotional initiatives tailored to different customer segments; and grow Eni’s presence in selected European markets where it can leverage on strong brand awareness and logistic advantages. Over the medium term, Eni plans to grow sales both in Italy and in the rest of Europe, targeting a combined volume of 17.4 billion liters by 2010 from 15.8 in 2006, corresponding to an average annual growth rate of 2.4%, and to match European best practice in terms of efficiency and service level. ITALY In 2006, retail volumes of refined products marketed on the Agip branded network (8.66 mmtonnes) were down 1% from 2005, with a market share of 29.3%; average throughput in terms of gasoline and diesel fuel was 2,463 kliters, down 1.8% from 2005. Eni completed the restructuring of its network by divesting the non-core portion of its assets in 2005. Eni’s network currently consists of 4,356 outlets with high levels of service and efficiency. Eni will continue investing on the upgrading of the network, targeting new opportunities arising from the shifting in customers’ behavior when refuelling the car. In fact, Eni plans to enhance its competitive position and improve its margins in retail operations by developing new service station formats according to European quality and service standards, increasing premium products offer, launching customer-focused marketing initiatives, also providing them an increasingly wide range of services and products beyond fuel, and differentiating fuel quality.

You&Agip In March 2007, Eni launched its You&Agip promotional campaign designed to boost customer loyalty to the Agip brand. It is an innovative formula intended to outperform traditional loyalty programmes for motorists, mainly by cancelling the usual time limits, as it is set to last for the next three years until December 31, 2009. Furthermore, the list of prizes will be kept constantly updated thanks to the high number of partners joining the initiative. The defining features of the You&Agip programme include giving customers the freedom how to accumulate points, when to spend them and what kind of reward to choose. Points can be accumulated not only by buying fuel, but also by buying all the other services and products sold at AgipCafè outlets. |  |

REST OF EUROPE In recent years, Eni’s strategy has focused on selectively growing its market share by means of the acquisition of assets in European areas with interesting profitability perspectives, mainly in Central-Eastern Europe (in particular Southern Germany, Austria, the Czech Republic and Hungary) in South-Eastern France and the Iberian Peninsula. In pursuing such growth, Eni has been able to reap synergies leveraging on the proximity of target areas to Eni’s production and logistic facilities. Over the last five years, retail volumes of refined products marketed in the rest of Europe have grown more than 50% (equal to a compound average growth rate of 9%). In 2006, retail sales were 3.82 mmtonnes, up 150 ktonnes from 2005, or 4.1%, particularly in Germany, Spain and Austria due to the ramp-up of new stations purchased or built with higher throughput than the average level of Eni’s network, while a few less efficient outlets were divested. Currently, Eni’s network in Europe consists of approximately 1,938 outlets with continental standards of service and quality. The main countries where Eni is present are: South-Central Germany with a 4.4% market share, Spain with 3.2%, Austria with 7.2%, Switzerland with 5.8% and South-Western France with 1.2% on national base. In the medium term, Eni will continue to deploy its strategy of selectively growing its market share. |  | Wholesale Eni sells gasolines and fuels: diesel fuel for automotiveuse and for heating purposes, for agricultural vehicles and for vessels, gasolines and fuel oil. Major customers are wholesalers, the agricultural and manufacturing industries, public utilities and transports. In 2006 Eni’s wholesale sales in Italy were 10.06 mmtonnes, down 0.42 mmtonnes from 2005, or 4%, reflecting mainly a decline in domestic consumption related to mild weather conditions in the fourth quarter of the year, with higher temperatures than the seasonal average. Sales on wholesale markets outside Italy (4.60 mmtonnes) increased 100 ktonnes, or 2.2%, mainly due to higher sales of diesel fuel in Germany and Spain.

In 2006, revenues were euro 365 million accounting for 5% of total revenues. Gross margin amounted to euro 119 million as compared to euro 65 million in 2005. This increase was supported by higher tariffs for the Scarabeo 3 and Scarabeo 5 semi-submersible platforms and higher activity levels of the Perro Negro 5 jack-up and Scarabeo 4 semi-submersible platform. The most significant contracts awarded during the period include: a 16-month long contract for the use of the semi-submersible drilling platform Scarabeo 7 in Nigeria for ExxonMobil; a 49-month long contract for the use of the semi-submersible drilling platform Scarabeo 5 in Norway for Statoil; a 27-month long contract for the use of the semi-submersible drilling platform Scarabeo 3 in Nigeria for Addax Petroleum. ONSHORE DRILLING Saipem operates in this area as main contractor for the major international oil companies executing its activity mainly in Saudi Arabia, North Africa and Peru, where it can leverage on its knowledge of markets, long-term relations with customers and integration with other business areas. In 2006, revenues were euro 248 million accounting for 4% of total revenues. Gross margin amounted to euro 38 million as compared to euro 26 million in 2005, reflecting a higher activity level. The contracts awarded during the period amounted to euro 338 million. |  | Capital expenditure In 2006, capital expenditure in the Engineering and Construction segment (euro 591 million) concerned: (i) the conversion of the Margaux tanker ship into an FPSO vessel that will operate in Brazil on the Golfinho 1 field; (ii) maintenance and upgrading of equipment; (iii) fabrication and installation of facilities in the offshore phase of the Kashagan project in Kazakhstan. Over the next four-year period, Saipem plans to invest approximately euro 3.5 billion directed to further upgrade its world-class fleet and to build local construction centers in order to strengthen relationship with key host countries, including Kazakhstan, Angola and Nigeria. New vessels which are planned to start operation in the next four years include a drilling rig as outlined above and a pipelayer designed to perform tasks in extreme environments.

ENI IN 2006 / GROUP RESULTS FOR THE YEAR

Group results for the year Trading environment Eni’s results from operations and the year to year comparability of its financial results are affected by a number of external factors which exist in the industry environment, including changes in oil, natural gas and refined products prices, industry-wide movements in refining and petrochemical margins and fluctuations in exchange rates and interest rates. Changes in weather conditions from year to year can influence demand for natural gas and some petroleum products for heating, thus affecting results of operations of the natural gas business and, to a lesser extent, of the refining and marketing business. The trading environment was broadly favorable in 2006 with Brent crude oil prices close to $60/bl, up 19.8% compared to 2005. Natural gas margins increased in 2006 compared to 2005, reflecting |  | a favorable trading environment and a softer impact of sector specific regulation in Italy. These positives were partially offset by declining refining margins, which were down by 34.4% compared to 2005. The euro appreciated by 1% over the dollar. Petrochemical product margins decreased in 2006 as compared to 2005, essentially due to higher purchase costs of oil-based feedstocks not being completely transferred to selling prices.

(a) |  | Unrealized profit in inventory concerned intragroup sales of goods and services recorded in the assets of the purchasing division as of end of the period.
From January 1, 2006 Eni’s subsidiaries operating in diversified sectors (such as real estate services, insurance and financing intermediation, R&D and training services) are reported in the “Corporate and financing companies” aggregate with exception of Tecnomare which is reported in the Exploration & Production division (previously all these diversified activities were reported in the “Other activities” aggregate). The “Other activities” aggregate includes only Syndial SpA, a subsidiary which runs minor petrochemical activities and reclamation and decommissioning activities pertaining to certain businesses which Eni exited in past years. In order to allow for comparison, 2005 data has been reclassified accordingly; 2004 data has not been reclassified.

The Group adjusted net profit for the year was supported by the increase reported in the: Exploration & Production division (up euro 1,093 million, or 17.7%), reflecting a better operating performance (up euro 2.860 million) as a result of higher realizations in dollars (oil up 22.4% and natural gas up 17.8%) combined with increased production volumes sold (up 10.2 mmboe). These positives were offset in part by higher operating costs and amortization charges, and increased exploration expenses. Adjusted net profit for the year was also negatively affected by the effects of exchange rates and a higher tax rate (from 51.8 to 53.9%); Gas & Power division (up euro 310 million, or 12.1%), reflecting a better operating performance (up euro 351 million) resulting from higher natural gas selling margins due to a favorable trading environment and the reduced impact of the tariff regime implemented by the Authority for Electricity and Gas with Resolution No. 248/2004. Growth in natural gas sales by consolidated subsidiaries (up 3.14 bcm, or 3.8%) and in volumes transported out-side Italy contributed positively. On a negative note, transportation activities in Italy posted lower operating results due to the tariff regime enacted by the Authority for Electricity and Gas with Resolution No. 166/2005 and distribution activities suffered from lower volumes. Adjusted net profit for the year was supported by a better performance of certain equity accounted entities; |  | Engineering & Construction division (up euro 72 million or 22%), reflecting a better operating performance against the backdrop of favorable trends in the demand for oilfield services. These increases were partly offset by lower adjusted net profit reported in the Refining & Marketing division (down euro 316 million, or 33.4%), due to a poor operating performance (down euro 424 million) dragged down by a weak refining environment, the appreciation of the euro over the dollar and the impact of a higher level of planned maintenance activity at refineries. Divisional results were also adversely impacted by the weaker performance of marketing activities in Italy due to lower sales as a consequence of the mild weather conditions of the fourth quarter.

NET CASH PROVIDED BY OPERATING ACTIVITIES Net cash provided by operating activities came in at euro 17,001 million. These cash flow enabled us to finance: (i) capital expenditure and investments for euro 7,928 million; (ii) dividend payments amounting to euro 4,832 million; (iii) the repurchase of own shares for euro 1,241 million. Cash from divestments (euro 329 million) and currency translation effects (approximately euro 650 million) also contributed to the reduction in net borrowings. NET BORROWINGS Net borrowings at December 31, 2006 were euro 6,767 million, representing a decrease of euro 3,708 million from December 31, 2005 due mainly to cash inflow generated by operating activities (euro 17,001 million). Currency translation effects also contributed to the reduction in net borrowings. Debts and bonds |  |

amounted to euro 11,699 million, of which euro 4,324 million were short-term (including the portion of long-term debt due within twelve months for euro 890 million) and euro 7,375 million were long-term. At December 31, 2006, leverage was 0.16, compared to 0.27 at December 31, 2005. DIVIDENDS AND SHARE REPURCHASES In 2006 total cash dividends to Eni shareholders amounted to euro 4,610 million (euro 5,070 million in 2005) of which euro 2,400 million pertained to the payment of the balance of the dividend for fiscal year 2005 and euro 2,210 million pertained to the payment of an interim dividend (euro 0.60 per share) for fiscal year 2006 paid in October 2006. On May 23-24, 2007, Annual General Meeting is convened to approve a unit dividend of euro 1.25 per share for fiscal year 2006 as proposed by Eni’s Board of Directors. This dividend proposal represents an increase of 13.6% compared to the unit dividend paid for fiscal year 2005 (euro 1.10 per share). If the proposal is approved by shareholders, in June Eni will pay a balance of euro 0.65 per share for fiscal year 2006. |  | From January 1 to December 31, 2006 a total of 53.13 million own shares were purchased at a cost of euro 1,241 million (on average euro 23.35 per share). From the beginning of the share buy-back plan (September 1, 2000), Eni has purchase 335 million of its own shares, equal to 8.36% of outstanding capital stock, at a total cost of euro 5,512 million (representing an average cost of euro 16.45 per share). In future, management plans to distribute significant amounts of cash to shareholders through an attractive and sustainable flow of dividends. Management also plans to continue paying dividends on an interim basis. Cash in excess (i.e. cash available after funding growth, paying dividend and maintaining a stable financial structure) will be returned to shareholders via continuing repurchase of own shares.

A strong commitment to sustainable development, involving each aspect of the business ranging from empowering people, to caring for the environment, developing communities, and technological innovation, has always stood at the heart of Eni’s strategies. In 2006, this commitment was confirmed and empowered. Eni is engaged in improving the sustainability of its business model over the time by means of strengthening the relationship with its stakeholders, improving social performance and increasing the value of intangible assets. Sustainability objectives are expected to become an integral part of its management, planning and development |  | processes. In light of this, for the first time in its history, Eni addressed in its industrial planning the key challenges and commitments it is expected to cope with in future years, as described in the table below. 2006 marks the first year in which Eni has published a Sustainability Report to communicate more effectively with stakeholders. We now have a more coherent approach to sustainability, and are even more committed to managing and developing our company in a responsible and accountable way. More detailed information on Eni’s commitment to sustainability is given on Eni’s website in the section Sustainability and in the Report on Sustainability.

MANAGEMENT AND DEVELOPMENT OF HUMAN RESOURCES Eni implemented various initiatives aimed at improving evaluation and development of human resources. In particular, Eni completed a plan of management rejuvenation and enhanced the tools for evaluation of development potential of resources, coupling the appraisals made at (hierarchical and functional) line level with those performed by external experts. These activities were addressed to key managers, developing young managers and newly recruited graduates. Eni performed an updating of policies directed to employees outside Italy and introduced compensation schemes adequate with the dynamics of international resource markets. With nearly 46% of its employees of non-Italian nationality, Eni has always considered diversity as an element generating value and the ability in managing it as a key factor for success. In the countries where it operates, Eni promotes the development of skills of local human resources and the construction of a shared culture by means of training initiatives addressing issues of intercultural diversity. TRAINING Eni considers training one of the strong points of the management of human resources. The number of hours dedicated to training and the number of employees participating in training initiatives are evidence of Eni’s significant commitment in Italy and outside Italy. In 2006, expenditure for training amounted to euro 57.2 million. In particular in Italy, a total of 1,167,633 training hours were provided to a total of 23,941 employees |  | (232 senior managers, 6,822 middle managers and senior staff, 12,180 employees and 6,192 workers) for a total of 90,319 participations. INDUSTRIAL RELATIONS Industrial relations within a consolidated and structured system represented an efficient and consistent support to Eni’s strategic choices and to the completion of reorganization processes underway. Internationally, Eni continued its dialogue with workers’ unions in specific forums such as the European Works Council. Eni’s Multicultural Training Project, which takes place every year in a different country with the cooperation of members of the EWC, held training courses in France addressed to 300 employees of Saipem SA. This course was awarded the first prize Etica&Impresa at the end of 2006. HEALTH Activities for the protection of health aim at improving general work conditions and are developed according to three main principles: protection of employees’ health; prevention of accidents and professional diseases; promotion of healthier behaviors and life styles in workplaces. Eni has a network of 307 own health care centers located in its main operating areas of these 217 are located outside Italy. A set of international agreements with the best local and international health centers guarantees efficient service and timely reactions to emergencies. In particular, outside Italy Eni promotes specific information campaigns for the protection of its employees, their families and local communities, such as those for the prevention of malaria (in Nigeria) and the prevention of HIV transmission (in Nigeria and Congo). SAFETY Eni has always been deeply engaged in the issue of the safety of its workers, of the people living in the areas where its industrial sites are located and of its producing assets. Its strategy has been based on: the dissemination of a safety culture within its organization; a common policy, specific guidelines for proper management systems meeting international standards; control, prevention and protection from exposure to dangerous situations; minimization of exposure to risk in all production activities.

In 2006, safety indicators have continued to improve, confirming a trend in place for many years to date. Both the injury frequency and severity rates hit historical lows: the former is calculated as ratio of injuries per million hours worked and was 3.07, down 3% from 2005; the latter is calculated as ratio of lost working days per thousand hours worked and was 0.09, down 10% from 2005. In 2006, Eni spent approximately euro 390 million mainly in facilities to improve safety levels, safety current measures, research and development and training. Responsibility towards the environment OUTLOOK The current focus on global environmental issues spurred by an increasingly tight regulatory framework and socio-political debate stimulates companies to devote a strong commitment to both local and worldwide environmental matters beyond the simple compliance with applicable rules and regulations. In addition, the current operating context is characterized by increasing risk aversion, due to the progressive internalization of environmental externalities and also the growing participation of local stakeholders in decision making processes. Companies are therefore required to be more transparent on their environmental performance, as they are subject to careful scrutiny by stakeholders. In all its activities, Eni is actively committed to reducing its environmental footprint, decreasing its energy and water consumption, reducing local pollution of air, water and soil as well as waste production and reclaiming discontinued industrial sites. Special attention is paid to the protection |  | of biodiversity. To this end, in 2006 Eni spent approximately euro 1.2 billion to preserve the environment and to support reclamation and remediation activities. RATIONAL USE OF NATURAL RESOURCES We manage natural resources aiming at their rational and sustainable use and conservation throughout all Eni’s operations. Coping with risks of climate change Eni has been devoting a great deal of effort to mitigate risks of climate change by reducing GHG emissions and energy consumption through a global strategy of carbon management aiming at: preferably developing fossil fuels with low carbon intensity, in particular natural gas; pursuing gas-electricity integration exploiting the high efficiency of combined cycles and co-generation; actively participating in the European emission trading scheme, promoting the reduction of emissions at its industrial sites; implementing Clean Development Mechanisms (CDM) and Joint Implementation Project (JIP) foreseen by the Kyoto protocol; progressively reducing gas flaring and gas venting associated to oil production creating the conditions for monetizing such volumes; developing fuel with low environmental impact and technologies for the separation and the geologic confinement of carbon dioxide and efficient production of hydrogen. Along these guidelines, Eni has been achieving such environmental results as to be featured as a low carbon dioxide emission company.

Water preservation Eni effectively manages water consumption by means of actions intended to develop recycling opportunities and minimize water discharge aiming in many instances at achieving better performances than those required by applicable laws. Eni invested to implement integrated production cycles entailing a limited and combined use of water, to build water treatment plants with the most updated technologies and to adopt monitoring systems capable of providing periodic controls of the most significant water parameters. In 2006, water consumption at 3.2 bcm was stable over the previous year. Soil protection The protection of soil and ground water is a crucial matter for the preservation of environment. For years, Eni has been carrying out numerous programs for the protection of soils and the reclamation of soils and ground waters. Eni’s business units are provided with an internal organization that takes care of managerial and technical aspects, using highly qualified external professionals to carry out reclaiming activities. Eni is also active in the area of waste produced by its industrial units with the aim of reducing its generation and improving its final destination by increasing recycling and recovery. Oil spills Production, handling and transport of oil products can give rise to spills of variable size. In order to protect the areas where it operates, Eni defined responsibilities and operating modes aimed at reducing the negative impact of oil spills. In 2006, a total of 139 oil spills were registered for a total of 6,150 bbl of oil spilled, confirming a downward trend. |  | MANAGING OPERATIONAL RISKS The broad scope of Eni’s activities involves a wide range of operational risks such as those of explosion, fire or leakage of toxic products, production of non biodegradable waste. All these events could possibly damage or even destroy plants, facilities, equipment and other property, cause injury or even death to persons or cause environmental damage. Eni adopted the most stringent guidelines for the evaluation and management of health, safety and environmental (HSE) risks, with the objective of protecting Eni’s employees, contractors and clients, the populations involved in its activity, the environment and being in compliance with local and international rules and regulations. Eni’s guidelines prescribe the adoption of international best practices in setting internal principles, standards and solutions. An ongoing process for identifying, evaluating and managing HSE risks is at the hearth of HSE operations in each phase of the business activity and is performed through the adoption of procedures tailored on the peculiarities of each business and industrial site. HSE risks are effectively managed through an integrated management system designed along the principles set in Eni’s Model of HSE operations. This is a general procedure to be applied in all its operating sites, based on an annual cycle of planning, implementation, control, review of results and definition of new objectives. The model is directed towards the prevention of risks, the systematic monitoring and control of HSE performance in a continuous improvement cycle subject also to audits by internal and independent experts. Any environmental emergency is managed by business units locally with their own organization under preset reaction plans to foreseeable events aimed at limiting damage and at activating adequate responses. Eni has two emergency rooms (at Milan and Rome) provided with real time monitoring systems for the collection of data on georeferenced maps for all Eni sites and logistics worldwide. Mathematical models are in place to assess dimension, temporal development and other consequences of certain catastrophic events and to enable a real-time planning of first-aid interventions to help mitigate consequences. In addition to its own emergency teams, Eni entered international agreements in order to maximize its ability to react in all its operating sites.

ENI IN 2006 / COMMITMENT TO SUSTAINABLE DEVELOPMENT

Community involvement Eni operates in over 70 countries respecting the human rights of populations, their territory and the environment, contributing to improving the quality of life and the socio-economic development of the communities where it is present. This commitment is the basis of entrepreneurial behaviors based on the respect for ethnic, social or cultural diversity of the various communities with which Eni interacts. The search for integration with varied social and cultural situations is part of Eni’s tradition. In order to favor a proper integration Eni: cooperates with national and local authorities and with international NGOs; sponsors initiatives that will proceed autonomously in the social, cultural and environmental fabric of the different communities; promotes dialogue with local communities on the industrial options by means of tool of active participation; favors the improvement of the socio-economic system where it operates wherever possible using local goods and services, consistently with its industrial requirements, in order to maximize local content; extends the initiatives for its personnel to their families and to local communities where it operates, in particular as concerns health. Eni’s main interventions for the protection and development of local communities concern: Italy: activities included in the intent protocol signed with the Basilicata Region for the Val d’Agri for an overall expenditure of approximately euro 160 million in the 1999-2019 period; Karachaganak: infrastructure projects requested by the local authorities for an overall expenditure of approximately euro 9 million, paid by the Consortium; Caspian Sea: infrastructure projects requested by the local authorities for an overall expenditure of approximately euro 309 million, paid by the Consortium; Libya: recruiting, training, health assistance, archaeology, industrial development, as provided for by the masterplan for an overall expenditure of approximately euro 110 million for a period of 8 years. |  | Innovation Our relentless commitment to technological research and innovation underscores a fundamental belief that technology is a key to increasing our competitive advantage over the long term and promoting sustainable growth. All the global challenges in future years require ingenuity and commitment: from the environmental and climate emergencies to the increasingly difficult access to hydrocarbon reserves; from the identification of discontinuities in the production of energy from renewable sources to the optimization of production processes up to the solution of problems existing in countries where Eni has been present for a long time or where it recently entered. We are conducting research aimed primarily at reducing the costs of finding and recovering hydrocarbons, upgrading heavy oils, monetizing stranded gas and protecting the environment. In the next four-year period, we plan to devote a significant amount of resources to research and development activities in the range of euro 1,5 billion in order to support our strategy in innovation. In 2006, Eni invested euro 222 million in research and development (euro 204 million in 2005). Of these 39% was directed to the Exploration & Production segment, 32% to the Refining & Marketing segment, 22% to the Petrochemical segment and 7% to the Engineering and Construction segment. In particular we moved forward on our breakthrough technologies: EST (Eni Slurry Technology) for the full exploitation of the heavy barrel, TAP (gas transportation at high pressure) and GTL (gas-to-liquids) for gas monetization, and GHG project as described below. Conversion of heavy crudes and fractions into light products (EST) Testing of this technology progressed at the Taranto demonstration plant. This proprietary technology is based on a process of catalytic hydroconversion in the slurry phase of non conventional crudes, extra heavy crudes and refining residues enabling it to fully convert asphaltenes (the hard fraction of heavy crudes) into naphtha, kerosene, diesel fuel. In 2007, Eni plans to complete the collection of information for designing and building its first industrial plant.

Gas to liquids project (GTL) In 2006, with the cooperation of IFP/Axens, Eni completed preparation of a technology handbook for this proprietary technology aiming at conversion of gas to liquids via Fischer-Tropsch synthesis and the basic engineering for a 37 kbbl/d industrial unit. GHG Project (Green House Gases) The Green House Gases research program progressed during the course of the year, aiming at verifying the industrial feasibility of the geological sequestration of carbon dioxide in depleted fields and salty aquifers. |  | A technical feasibility study of the geological sequestration of carbon dioxide has been completed and in 2007 Eni expects to start testing this project in a field. Natural gas high pressure transport (TAP) The TAP project aims to develop an advanced long distance, high capacity, high pressure and high grade solutions for gas transport targeting: transport on distances over 3,000 kilometers; volumes to be transported in the range of 20-30 billion cubic meters/year; pressure equal to or higher than 15 MPa; use of high and very high grade steel. The TAP technology is expected to allow a decrease in gas consumption of compressor stations. In 2006, testing progressed on two infrastructures (one integrated in the system of Snam Rete Gas), a technology handbook was released and a hypothetical 3,400 kilometer long gasline in X100 steel in Central Asia was designed.

Financial Information
SUMMARY OF ACCOUNTING POLICIES AND PRACTICES
Eni prepares its consolidated financial statements in accordance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB) and adopted by the European Commission.
The consolidated financial statements of Eni include accounts of the parent company Eni SpA and of all Italian and foreign significant subsidiaries in which Eni directly or indirectly holds the majority of voting rights or is otherwise able to exercise control as in the case of “de facto” controlled entities. Control comprises the power to govern the financial and operating policies of the investee so as to obtain rewards from its activities. Insignificant subsidiaries, jointly controlled entities, and other entities in which the group is in a position to exercise a significant influence through participation in the financial and operating policy decisions of the investee are generally accounted for under the equity method of accounting.
Revenues from sales of crude oil, natural gas, petroleum and petrochemical products are recognized when the products are delivered and title passes to the customer. Revenue recognition in the Engineering & Construction division is based on the stage of completion of contracts as measured on the cost-to-cost basis applied to contractual revenues.
Stock-based compensation to employees is recognized in the profit and loss account based on the fair value of grants awarded to the employee; the portion relevant to the year is calculated pro rata over the vesting period of relevant grants.
Eni enters into various derivative financial transactions to manage exposures to certain market risks, including foreign currency exchange rate risks, interest rate risks and commodity risks. From January 1, 2005, such derivative financial instruments are assets and liabilities recognized at fair value starting on the date on which a derivative contract is entered into and are subsequently reassessed at fair value. Derivatives are designated as hedges when the hedging relationship between the hedged item or transaction and the hedging instrument is highly effective and formally documented. Changes in the fair value of hedging derivatives are recognized: (i) for fair value hedges, hedging the exposure to changes in the fair value of a recognized asset or liability, in the profit and loss account; (ii) for cash flow hedges, hedging exposure to variability in cash flows, the effective portion is recognized directly in equity, while the ineffective portion in the profit and loss account; subsequently amounts taken to equity are transferred to the profit and loss account when the hedged transaction occurs. Changes in fair value of derivatives held for trading purposes, i.e. derivatives for which the hedging relationship is not formally documented or is ineffective, are recognized in the profit and loss account. Eni does not enter into derivative transactions on a speculative basis.
Inventories of crude oil, natural gas and oil products are stated at the lower of cost and net realizable value. Cost is determined based on the weighted-average cost method. Contract work in progress is recorded on the basis of contractual considerations by reference to the stage of completion of a contract measured on a cost-to-cost basis.
Property, plant and equipment and intangible assets are stated at cost less accumulated depreciation and accumulated, losses impairment. Depreciation, depletion and amortization of oil and gas properties (capitalized costs incurred to obtain access to proved reserves and to provide facilities for extracting, gathering and storing oil and gas) is calculated based on the Unit-Of-Production (UOP) method on proved reserves or proved developed reserves. Exploratory costs (costs associated with exploratory activities for oil and gas producing properties) are capitalized and fully amortized as incurred. Other tangible assets and intangibles with a defined useful life are amortized systematically, based on the straight-line method. Goodwill and intangibles lacking a defined useful life are not amortized but are reviewed periodically for impairment. Eni assesses its property, plant and equipment and intangible assets, including goodwill, for possible impairment if there are events or changes in circumstances that indicate that the carrying values of the assets are not recoverable.

ENI IN 2006 / FINANCIAL INFORMATION

Such indicators include changes in the Group’s business plans, changes in commodity prices leading to unprofitable performance and, for oil and gas properties, significant downward revisions of estimated proved reserve quantities.
Asset retirement obligations, that may be incurred for the dismantling and removal of assets and the reclamation of sites, are evaluated estimating the costs to be incurred when the asset is retired. Future estimated costs are discounted when the settlement date is in a long-time horizon in order to reflect the time value of money. Initial estimate is reviewed periodically to reflect changes in circumstances and other factors surrounding the estimate, including the discount rates. The company recognizes material provisions for asset retirement in the upstream business. No significant asset retirement obligations associated with any legal obligations to retire refining, marketing and transportation (downstream) and chemical long-lived assets are generally recognized, as indeterminate settlement dates for the asset retirement prevent estimation of the fair value of the associated asset retirement obligation.
Provisions, including environmental liabilities, are recognized when the group has a present obligation (legal or constructive) as a result of a past event, when is probable that an outflow of resources embodying economic benefit will be required to settle the obligation, and when the obligation can be reliably estimated. The initial estimate to settle the obligation is discounted when the effect of the time value of money is material. The estimate is reviewed periodically to take account of changes in costs expected to be incurred to settle the obligation and other factors, including changes in the discount rates.
Eni is a party to a number of legal proceedings arising in the ordinary course of business. Although Eni’s management does not currently expect a material adverse effect on Eni’s financial position and results of operations on the basis of information available to date and taking account of existing provisions, there can be no assurance that in the future Eni will not incur material charges in connection with pending litigations as new information becomes available and new developments may occur. For further information about pending litigations, see “Legal proceedings”, note 25 to the consolidated financial statements of Eni’s Annual Report 2006.
The preparation of consolidated financial statements requires management to apply accounting methods and policies that are based on difficult or subjective judgments, estimates based on past experience and assumptions determined to be reasonable and realistic based on the related circumstances. The application of these estimates and assumptions, particularly those affecting estimates of proved reserves, asset impairments and contingent liabilities, affects the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of income and expenses during the reporting period. Actual results may differ from these estimates given the uncertainty surrounding the assumptions and conditions upon which estimates are based.
For further information regarding accounting policies and practices, see “Evaluation criteria” and “Use of accounting estimates” in the Notes to the consolidated financial statements of Eni’s Annual Report 2006.

NON-GAAP MEASURES
Reconciliation of reported operating profit and net profit to results on an adjusted basis
Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Further, finance charges on finance debt, interest income, charges or income deriving from the fair value evaluation of derivative financial instruments held for trading purposes, and exchange rate differences are excluded when determining adjusted net profit of each business segment.
The taxation effect of such items excluded from adjusted net profit is determined based on the specific rate of taxes applicable to each item, with the exception for finance charges or income, to which the Italian statutory tax rate of 33% is applied.
Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them to facilitate comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment.
The following is a description of items which are excluded from the calculation of adjusted results.
Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted-average cost method of inventory accounting.
Special items include certain relevant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non recurring material income or charges are to be clearly reported in the management’s discussion and financial tables.
Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition the effect of the fair value evaluation of derivative financial instruments held for trading purposes and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charge or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charge pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production division).
Finance charges or interest income and related taxation effects excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies.
For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and reported net profit see tables below.

SUMMARIZED GROUP BALANCE SHEET
Summarized Group Balance Sheet aggregates the amount of assets and liabilities derived from the statutory balance sheet in accordance with functional criteria which consider the enterprise conventionally divided into the three fundamental areas focusing on resource investments, operations and financing. Management believes that this summarized group balance sheet is useful information in assisting investors to assess Eni’s capital structure and to analyze its sources of funds and investments in fixed assets and working capital. Management uses the Summarized Group Balance Sheet to calculate key ratios such as return on capital employed (ROACE) and the proportion of net borrowings to shareholders’ equity (leverage) intended to evaluate whether Eni’s financing structure is sound and well-balanced.

Leverage is a measure of a company’s level of indebtedness, calculated as the ratio between net borrowings which is calculated by excluding cash and cash equivalents and certain very liquid assets from financial debt, and shareholders’ equity, including minority interests. Management makes use of leverage in order to assess the soundness and efficiency of the Group balance sheet in terms of optimal mix between net borrowings and net equity, and to carry out benchmark analysis with industry standards.
In the medium term, management plans to maintain a strong financial structure targeting a level of leverage up to 0.40.

SUMMARIZED GROUP CASH FLOW STATEMENT AND CHANGE IN NET BORROWINGS
Eni’s Summarized Group Cash Flow Statement derives from the statutory statement of cash flows. It allows to create a link between changes in cash and cash equivalents (deriving from the statutory cash flows statement) occurred from the beginning of period to the end of period and changes in net borrowings (deriving from the summarized cash flow statement) occurred from the beginning of period to the end of period. The measure enabling to make such a link is represented by free cash flow which is the cash in excess of capital expenditure needs. Starting from free cash flow it is possible to determine either: (i) changes in cash and cash equivalents for the period by adding/deducting cash flows relating to financing debts/receivables (issuance/repayment of debt and receivables related to financing activities), shareholders’ equity (dividends paid, net repurchase of own shares, capital issuance) and the effect of changes in consolidation and of exchange differences; (ii) changes in net borrowings for the period by adding/deducting cash flows relating to shareholders’ equity and the effect of changes in consolidation and of exchange differences.

ROACE
Return on Average Capital Employed for the Group, on an adjusted basis is the return on Group average capital invested, calculated as the ratio between net adjusted profit before minority interests, plus net finance charges on net borrowings, less the related tax effect and net average capital employed. The tax rate applied on finance charges is the Italian statutory tax rate of 33%. The capital invested as of period-end used for the calculation of net average capital invested is obtained by deducting inventory gains or losses as of in the period, rectified from the related tax effect.
ROACE by business segment is determined as the ratio between adjusted net profit and net average capital invested pertaining to each business segment and rectifying the net capital invested as of period-end, from net inventory gains or losses (after applying the business segment specific tax rate).

PRODUCTION SHARING AGREEMENTS (PSA)
In PSAs the national oil company awards the execution of exploration and production activities to the international oil company (contractor). The contractor bears the mineral and financial risk of the initiative and, when successful, recovers capital expenditure and costs incurred in the year (cost oil) by means of a share of production. This production share varies along with international oil prices. In certain PSAs changes in international oil prices affect also the share of production to which the contractor is entitled in order to remunerate its capital invested (profit oil) after costs incurred are repaid by cost oil. A similar scheme applies to buy-back contracts.
POSSIBLE RESERVES
Amounts of hydrocarbons that have a lower degree of certainty than probable reserves and are estimated with lower certainty, for which it is not possible to foresee production.
PROBABLE RESERVES
Amounts of hydrocarbons that are probably, but not certainly, expected to be extracted. They are estimated based on known geological conditions, similar characteristics of rock deposits and the interpretation of geophysical data. Further uncertainty elements may concern: (i) the extension or other features of the field; (ii) economic viability of extraction based on the terms of the development project; (iii) existence and adequacy of transmission infrastructure and/or markets; (iv) the regulatory framework.
PROVED RESERVES
Proved reserves are estimated volumes of crude oil, natural gas and gas condensates, liquids and associated substances which are expected to be retrieved from deposits and used commercially, at the economic and technical conditions applicable at the time of the estimate and according to current legislation. Proved reserves include: (i) proved developed reserves: amounts of hydrocarbons that are expected to be retrieved through existing wells, facilities and operating methods; (ii) non developed proved reserves: amounts of hydrocarbons that are expected to be retrieved following new drilling, facilities and operating methods. On these amounts the company has already defined a clear development expenditure program which is expression of the company’s determination.
RECOVERABLE RESERVES
Amounts of hydrocarbons included in different categories of reserves (proved, probable and possible), without considering their different degree of uncertainty.
RESERVE REPLACEMENT RATIO
Measure of the reserves produced replaced by proved reserves. Indicates the company’s ability to add new reserves through exploration and purchase of property. A rate higher than 100% indicates that more reserves were added than produced in the period. The ratio should be averaged on a three-year period in order to reduce the distortion deriving from the purchase of property or upstream assets, the revision of previous estimates, enhanced recovery, improvement in recovery rates and changes in the value of reserves – in PSAs – due to changes in international oil prices.
RESERVE LIFE INDEX
Ratio between the amount of reserves at the end of the year and total production for the year.

ENI IN 2006 / DIRECTORS AND OFFICERS

“Salaries and other elements” report base salaries paid to the CEO, the General Mangers of Eni’s divisions and other managers with strategic responsibilities, and indemnities paid upon termination of the employment contract. Long-term incentive schemes In March 2006, the Board of Directors approved a new long-term incentive scheme for senior managers of Eni Group companies (excluding listed subsidiaries), as proposed by the Compensation Committee. This new scheme is intended to motivate more effectively and retain managers, linking incentives to targets and performance achieved in a tighter way than previous incentives schemes. This new incentive scheme applies to the 2006-2008 three year period and is composed of a deferred bonus, linked to the achievement of certain business growth and |  | operating efficiency goals, and stock option awards based on the achievement of certain targets of total shareholder return. This scheme has a structure intended to balance monetary and stock-based components of the remuneration, as well as to link economic and operating performance to share performance in the long term. Deferred bonus This leg of the long-term incentive scheme envisages a basic bonus paid after three years according to a variable amount equal to a percentage ranging from 0 to 170% of the amount established for the target performance in relation to the performances achieved in a three-year period as approved by the Board of Directors. Performances are measured in terms of achievement of annual EBITDA targets preset for the 2006-2008 period, as assessed by comparing actual results with set targets under a constant trading environment for each year. The following table sets out the basic bonus awarded in the year 2006 to the CEO and to the General Managers of Eni’s Divisions, and the total amount awarded to other managers with strategic responsibilities.

ENI IN 2006 / DIRECTORS AND OFFICERS

Stock option plan Eni offers managers of Eni Group companies holding positions of significant responsibility for achieving profitability or strategic targets, the opportunity to acquire a shareholding in the company as an element of remuneration through the award of options for purchasing Eni’s treasury shares. Differently from previous schemes, the 2006-2008 stock option plan introduced a performance condition upon which options can be exercised. At the end of each vesting period with a three-year duration, the Board of Directors determines the number of exercisable options, in a percentage ranging from 0% to 100% of the total amount awarded for each year of the plan, depending on the performance of Eni shares measured in terms of Total Shareholders Return as compared to that achieved |  | by a panel of major international oil companies in terms of capitalization. On July 27, 2006, the Board of Directors approved: (i) the award pertaining to 2006 within the three-year period covered by the plan; (ii) its rule; and (iii) the criteria to be followed in the identification of eligible managers.

Investor Information ANNUAL GENERAL MEETING The 2007 Annual General Shareholders’ Meeting is convened on May 23-24, 2007, on first and second call respectively, in Rome at one of Eni’s headquarters, Via del Serafico, 89/91, at 10:00 am (CET). A notice convening the meeting is published on April 14, 2007, on the Official Gazette of the Republic of Italy and can be found at eni.it>Press Room>Notice in newspaper. Beneficial Owners of ADRs, listed on the New York Stock Exchange, each ADR representing two Eni ordinary shares, who are recorded in Eni ADRs register of JPMorgan Chase Bank, N.A. by May 4, 2007 will be entitled to participate in the Meeting or to exercise votes by mail, after having complied with the deposit and registration requirements. Beneficial Owners who have taken advantage of Proxy Vote or Vote by Mail options are entitled to assist at the Meeting upon written request to be made to JPMorgan Chase Bank, N.A., ADRs Depositary. Eni SpA’s Corporate Secretary is available for any further information Shareholders may need at the toll-free number 800 940 924 (for calls from abroad Italy: 80011223456) or fax number + 39 0659822233. The Notice and the documentation regarding the Shareholders’ Meeting will be available on www.eni.it and may be requested by e-mail at segreteriasocietaria.azionisti@eni.it or by calling the above-mentioned toll-free numbers. |  | DIVIDENDS Eni announces dividends on its ordinary shares in terms of euro. In the Annual General Meeting, shareholders approve the dividend proposal made by the Board. For the fiscal year 2006, the Board proposed a dividend of euro 1.25 per share. Eni paid an interim dividend for fiscal year 2006 amounting to euro 0.60 per share to shares on the register at the ex-dividend date (October 23, 2006). Following shareholders approval, the balance of euro 0.65 to the amount proposed by the Board is scheduled for June 21, 2007 (being the ex-dividend date June 18, 2007). Holders of ADRs will receive euro 1.30 per ADR, payable on June 28, 2007 to ADR holders as of the June 20, 2007 record date. Eni intends to continue paying interim dividends in the future. Following Italian tax laws in force from January 1, 2004, dividends do not entitle to a tax credit and are either subject to a withholding tax or partially cumulated to the receiver’s taxable income, depending on the receiver fiscal status. Holders of ADRs receive their dividends in US dollars. The rate of exchange used to determine the amount in dollars is equal to the official rate recorded on the date of dividend payment in Italy (June 21). On ADR payment date, JPMorgan Chase Bank, N.A. pays the dividend less the amount of withholding tax under Italian law (currently 27%) to all Depository Trust Company Participants, representing payment of Eni SpA’s gross dividend. Under a convention between the United States of America and Italy for the Avoidance of Double Taxation (“Treaty”), US residents who hold less than 10% of the Company, as defined in the Treaty, can effectively reduce the tax liability on dividends, from 27% to 15%. By submitting to JPMorgan Chase Bank, NA (“JPMorgan”) certain required documents with respect to each dividend payment, US holders of ADRs will enable the Italian Depositary bank and JPMorgan as ADR Depositary to pay the dividend at the reduced withholding tax rate of 15%. US shareholders can obtain relevant documents as well as a complete instruction packet to benefit from this tax relief by contacting Eni’s Corporate Secretary or JPMorgan - Globe Tax Services at 1-800-929-5484.

Eni’s net profit for the first quarter of 2007 was euro 2,588 million, down euro 386 million from the first quarter of 2006, or 13.0%, due essentially to a lower operating performance (down euro 490 million, or 8.8%) as result of a decline in the Exploration & Production division, partially offset by a |  | positive performance delivered by Eni‘s downstream and the Engineering & Construction businesses. This reduction in net profit was also due to higher net financial expenses mainly owing to losses on the fair value evaluation of certain financial derivative instruments.

Eni’s adjusted net profit amounted to euro 2,680 million, down 9.3% from the first quarter 2006. Adjusted net profit is arrived at by excluding an inventory holding loss of euro 97 million and special income of euro 5 million net. Special charges concerned essentially environmental charges and employee redundancy incentives, offset by a gain from the settlement reached by Syndial and Dow |  | Chemical on some contractual issues pending between the two companies. Return on Average Capital Employed (ROACE) calculated on an adjusted basis for the twelve-month period ending March 31, 2007 was 22.7% (21.8% for the twelve-month period ending March 31, 2006).

ENI REPORT ON THE FIRST QUARTER OF 2007

The trading environment was affected by lower oil prices with Brent crude prices averaging $57.75 per barrel, down 6.5% compared to the first quarter of 2006, and the appreciation of the euro over the dollar (up 9.0%). These negatives were partially offset by: (i) favorable trends in |  | energy and exchange rate parameters used in determining purchase and selling prices of natural gas; (ii) an increase in refining margins on the Brent crude marker (up 3.7%), and (iii) higher sales margins on petrochemical products.

The following table sets forth adjusted net profit1 by division:

2,355 |  |  | Eni's adjusted net profit |  | 2,954 |  |  | 2,680 |  |  | (274 | ) |  | (9.3 | )

(a) |  | Unrealized profit in inventory concerned intra-group sales of goods and services recorded at period end in the equity of the purchasing business segment.

The decline in the Group adjusted net profit was owed to the reduction of adjusted net profit registered in the Exploration & Production division (down euro 686 million or 32.7%), due to a weaker operating performance (down euro 1,119 million or 26.3%) which was adversely impacted by the appreciation of the euro over the dollar (up 9.0%), a decline in production sold (down 9.5 mmboe/d), lower oil realizations in dollars (oil down 3.3%), and higher exploration expenses. The decline in the adjusted net profit of the Exploration & Production division was partly offset by a higher adjusted net profit reported in the divisions: - Gas & Power (up euro 280 million or 31.9%), as a result of an improved operating performance (up euro 480 million or 40%) reflecting higher natural gas selling margins supported mainly by a favorable trading environment, relating in particular to trends in the euro vs dollar exchange rate. This divisional performance |  | benefited also from a positive evolution of the regulatory framework in Italy. These positives were partly offset by lower natural gas sales (down 2.87 bcm or 10.4%) hurt by lower European gas demand due to the unusually mild weather conditions registered in the first quarter 2007; - Refining & Marketing (up euro 27 million or 31.4%), reflecting an improved refining performance boosted by higher processed volumes and better yields also in light of lower maintenance shutdowns; - Petrochemical (up euro 63 million, or 393.8%), due to an improved operating performance (up euro 99 million) reflecting a recovery in product selling margins; - Engineering & Construction (up euro 58 million, or 66.7%) reflecting an improved operating performance (up euro 98 million) against the backdrop of favorable demand trends in oilfield services.

Eni’s net sales from operations (revenues) for the first quarter of 2007 (euro 21,913 million) were down euro 1,671 million, a 7.1% decline from the first quarter of 2006, primarily reflecting the impact of the appreciation of the euro versus the dollar (up 9%) and the decline in oil prices, as well as sold production of hydrocarbons and natural gas sales. These negative factors were offset in part by higher activity levels in the Engineering & Construction segment and higher gas prices. Revenues generated by the Exploration & Production segment (euro 6,361 million) declined by euro 1,051 million, down 14.2%, essentially due to the impact of the appreciation of the euro versus the dollar and the decline in oil realizations in dollars (down 3.3%) and lower hydrocarbon production sold (down 9.5 million boe). These factors were offset in part by higher gas prices (up 1.3%). Revenues generated by the Gas & Power segment (euro 8,543 million) declined by euro 591 million, down 6.5%, essentially due to lower natural gas volumes sold by consolidated subsidiaries (down 2.87 billion cubic meters or 10.4%) and lower volumes transported and distributed as a consequence of an unusually mild winter. |  | These negative factors were offset in part by increased natural gas prices, related in particular to trends of energy parameters to which gas prices are contractually indexed. Revenues generated by the Refining & Marketing segment (euro 7,943 million) declined by euro 1,337 million, down 14.4%, essentially due to lower international prices for oil and refined products and the effect of the appreciation of the euro over the dollar. An additional negative factor was the decline in volumes marketed on retail and wholesale markets in Italy (down 410 ktonnes, or 8%) related to the competitive pressure and a mild winter that reduced the demand for heating oil. Revenues generated by the Petrochemical segment (euro 1,674 million) were substantially stable from the first quarter of 2006. Net sales from operations generated by the Engineering & Construction segment (euro 1,962 million) increased by euro 652 million, up 49.8%, due to increased activity levels in the Offshore and Onshore construction business.

Operating expenses for the first quarter of 2007 (euro 15,462 million) declined by euro 1,277 million from the first quarter of 2006, down 7.6%, essentially due to: (i) lower prices for oil-based and petrochemical feedstocks and for natural gas reflecting an appreciation of the euro versus the dollar; (ii) lower supplies of natural gas in line with lower sales and the fact that in the first quarter of 2006 higher gas supplies costs were recorded due to a climatic emergency; (iii) lower costs for refinery maintenance activity. |  | Labor costs (euro 878 million) increased by euro 51 million, up 6.2%, due mainly to an increase in unit labor cost in Italy and outside Italy and an increase in the average number of employees outside Italy in the Engineering & Construction segment related to higher activity levels.

Adjusted operating profit was euro 5,523 million, down 5.1% from a year ago. Adjusted net profit is arrived at by excluding an inventory holding loss of euro 155 million and special income of euro 7 million net. The main factors affecting this decline were the operating performance of the Exploration & Production division (down euro 1,119 million from the first quarter 2006, or 26.3%), due primarily to the 9% appreciation of the euro versus the dollar, lower production sold (down 9.5 mmboe), lower oil realizations in dollars (down 3.3%) and higher expenses incurred in connection with exploratory activity. These declines were partly offset by an increase in adjusted operating profit in the following segments: (i) Gas & Power (up euro 480 million or 39.9%), reflecting primarily increased natural gas selling margins mainly owing to a favorable trading environment, relating in particular to trends in the euro vs dollar exchange rate. |  | A favorable evolution of the regulatory framework in Italy also supported operating profit. These positives were partly offset by a decline in natural gas sales (down 2.87 bcm, or 10.4%) due to lower European gas demand as a consequence of the unusually mild weather conditions of the first quarter 2007, partly offset by a growth in sales in certain target markets in the rest of Europe; (ii) Petrochemical (up euro 99 million or 430.4%) related to an increase in selling margins; (iii) Engineering & Construction (up euro 98 million or 125.6%) due to a positive trend in the market for oilfield services; (iv) Refining & Marketing (up euro 31 million or 34.8%) reflecting primarily a better operating performance delivered by the refining activity, which was boosted by higher processed volumes and better yields also in light of lower maintenance shutdowns.

ENI REPORT ON THE FIRST QUARTER OF 2007

Net financial expense In the first quarter of 2007 net financial expense (euro 133 million) increased by euro 175 million from the first quarter of 2006. This increase was due to: (i) losses recognized on the fair value evaluation of certain financial derivatives instruments recorded in the profit and loss account instead of being recognized in connection with related assets, liabilities and commitments because these instruments do not meet the formal criteria to |  | lbe assessed as hedge under IFRS, including the time value component of certain cash flow hedges Eni entered into to hedge risk on commodities in the quarter (see comment to net working capital below); (ii) the impact of higher interest rates on euro (Euribor up 1.2 percentage points) and dollar loans (Libor up 0.6 percentage points), offset in part by a decline in average net borrowings.

SUMMARIZED GROUP BALANCE SHEET

Summarized group balance sheet aggregates the amount of assets and liabilities derived from the statutory balance sheet in accordance with functional criteria which consider the enterprise conventionally divided into the three fundamental areas focusing on resource investments, operations and financing. Management believes that this summarized group balance sheet is useful information in assisting investors to |  | assess Eni's capital structure and to analyze its sources of funds and investments in fixed assets and working capital. Management uses the summarized group balance sheet to calculate key ratios such as return on capital employed (ROACE) and the proportion of net borrowings to shareholders' equity (leverage) intended to evaluate whether Eni's financing structure is sound and well-balanced.

ENI REPORT ON THE FIRST QUARTER OF 2007

Fixed assets totalled euro 54,644 million, representing an increase of euro 410 million from December 31, 2006 (euro 54,234 million). Capital expenditure for the period (euro 2,013 million) was offset in part by provisions for depreciation, amortization and impairments (euro 1,627 million) and the effect of the appreciation of the euro over the dollar in the translation of financial statements of subsidiaries operating with currencies other than the euro. Other assets included, for a book value of $829 million (corresponding to euro 622 million at the March 31, 2007 EUR/USD exchange rate), the assets related to the service contract for oil activities in the Dación area of the Venezuelan branch of Eni's subsidiary Eni Dación BV. With effective date April 1, 2006, the Venezuelan State oil company Petróleos de Venezuela SA (PDVSA) unilaterally terminated the Operating Service Agreement (OSA) governing activities at the Dación oil field where Eni acted as a contractor, holding a 100% working interest. As a consequence, starting on the same date, operations at the Dación oil field are conducted by PDVSA. Eni proposed to PDVSA to agree on terms in order to recover the fair value of its Dación assets. On November 2006, based on the bilateral investments treaty in place between the Netherlands and Venezuela (the “Treaty”), Eni commenced a proceeding before an International Centre for Settlement of Investment Disputes (ICSID) Tribunal (i.e., a tribunal acting under the auspices of the ICSID Convention and being competent pursuant to the Treaty) to claim its rights. Despite this action, Eni is still ready to negotiate a solution with PDVSA to obtain a fair compensation for its assets. Based on the opinion of its legal consultants, Eni believes to be entitled to a compensation for such expropriation in an amount equal to the market value of the OSA before the expropriation took place. The market value of the OSA depends upon its expected profits. In accordance with established international practice, Eni has calculated the OSA’s market value using the discounted cash flow method, based on Eni’s interest in the expected future hydrocarbon production and associated capital expenditures and operating costs, and applying to the projected cash flow a discount rate reflecting Eni’s cost of capital as well as the specific risk of concerned activities. Independent evaluations carried out by a primary petroleum consulting firm fully support Eni’s internal evaluation. The estimated net present value of Eni’s interest in the Dación |  | field, as calculated by Eni, is higher than the net book value of the Dación assets which consequently have not been impaired. In accordance with the ICSID Convention, a judgement by the ICSID Tribunal awarding compensation to Eni would be binding upon the parties and immediately enforceable as if it were a final judgement of a court of each of the States that have ratified the ICSID Convention. The ICSID Convention was ratified in 143 States. Accordingly, if Venezuela fails to comply with the award and to pay the compensation, Eni could take steps to enforce the award against commercial assets of the Venezuelan Government almost anywhere those may be located (subject to national law provisions on sovereign immunity). At March 31, 2007, net working capital totalled euro 6,669 million, representing a decrease of euro 1,472 million from December 31, 2006 mainly due to: (i) higher taxes payable and an increase in reserves for taxation related to taxes due for the period and the fact that excise taxes on oil products marketed in Italy in the first 15 days of December are settled within the end of this month, instead of being paid in the following month as in the rest of the year; (ii) the increase in Other operating liabilities related to a euro 575 million loss recognized on the fair value evaluation of certain financial derivative instruments. The Group entered into such transactions in order to hedge cash flow expected in the 2008-2011 period from the sale of approximately 2% of Eni’s proved hydrocarbon reserves as of 2006 year-end in connection with its purchase of proved and unproved property onshore in Congo (from the French company Maurel & Prom) and in the Gulf of Mexico (from the US company Dominion) finalized in February and April 2007, respectively. In light of this, Eni put in place certain forward sale contracts at a fixed price and call and put options with the same date of exercise. These options can be exercised in presence of crude oil market prices higher or lower compared with contractual prices. This treatment does not apply to the time value component arising from market price fluctuations within the range provided by these call and put options which is recognized in the profit and loss account under the item net financial expenses because the hedging relationship is ineffective. The share of the Exploration & Production, Gas & Power and Refining & Marketing divisions on net capital employed was 89% (90% at December 31, 2006).

Return On Average Capital Employed (ROACE)

Return on Average Capital Employed for the Group, on an adjusted basis is the return on the Group average capital invested, calculated as the ratio between net adjusted profit before minority interest, plus net finance charges on net borrowings net of the related tax effect, and net average capital employed. The tax rate applied on finance charges is the Italian statutory tax rate of 33%. The capital invested as of period-end used for the calculation of net average capital invested is |  | obtained by deducting inventory holding gains or losses for the period, net of the related tax effect. ROACE by business segment is determined as the ratio between adjusted net profit and net average capital invested pertaining to each business segment, adjusting net capital invested as of period-end by net inventory gains or losses (net of the related tax effect based on each business segment specific tax rate).

Net borrowings and leverage

Leverage is a measure of a company's level of indebtedness, calculated as the ratio between net borrowings which is calculated by excluding cash and cash equivalents and certain very liquid assets from financial debt and shareholders' equity, including minority interests. Management makes use of leverage in order to assess the soundness and efficiency of the Group balance |  | sheet in terms of optimal mix between net borrowings and net equity, and to carry out benchmark analysis with industry standards. In the medium term, management plans to maintain a strong financial structure targeting a level of leverage up to 0.40.

Net borrowings at March 31, 2007 were euro 3,852 million, representing a decrease of euro 2,915 million from December 31, 2006 due mainly to cash inflow generated by operating activities (euro 5,563 million). Total debt amounted to euro 16,470 million, of which euro 9,670 million were short-term (including the portion of long-term debt due within 12 months for euro 870 million) and euro 6,800 million were long-term. Short-term finance debt increased by euro 5,380 million compared with December 31, 2006. This increase was due to the need to collect the necessary funds to participate in a bid to |  | purchase ex-Yukos gas assets (see “Post closing events”). Eni made recourse to undrawn borrowing facilities. These funds were placed in escrow resulting in a corresponding increase of non-operating receivables financing, with a neutral impact on net borrowings as of the end of the period. At March 31, 2007, leverage – ratio between net borrowings and shareholders' equity – was 0.09, compared with 0.16 at December 31, 2006.

SUMMARIZED CASH FLOW STATEMENT AND CHANGE IN NET BORROWINGS

Eni's summarized group cash flow statement derives from the statutory statement of cash flows. It allows to create a link between changes in cash and cash equivalents (deriving from the statutory cash flows statement) occurred from the beginning of period to the end of period and changes in net borrowings (deriving from the summarized cash flow statement) occurred from the beginning of period to the end of period. The measure enabling to make such a link is represented by free cash flow which is the cash in excess of capital expenditure needs. Starting from free cash flow it is |  | possible to determine either: (i) changes in cash and cash equivalents for the period by adding/deducting cash flows relating to financing debts/receivables (issuance/repayment of debt and receivables related to financing activities), shareholders' equity (dividends paid, net repurchase of own shares, capital issuance) and the effect of changes in consolidation and of exchange rate differences; (ii) changes in net borrowings for the period by adding/deducting cash flows relating to shareholders' equity and the effect of changes in consolidation and of exchange rate differences.

POST CLOSING EVENTS

Upstream asset acquisition in the Gulf of Mexico On April 30, 2007 Eni agreed to acquire the Gulf of Mexico upstream activity of Dominion, one of the major American energy companies, listed on the New York Stock Exchange at the agreed price equal to US $4,757 million inclusive of exploration assets for US $680 million. The transaction includes production, development and exploration assets located in deepwater Gulf of Mexico. The acquisition will increase Eni’s equity production in the Gulf of Mexico from the current 36 kboepd to more than 110 kboepd in the second half of 2007 and the proved and probable equity reserves by 222 million boe, at an implied cost per barrel of US $18.40. In the 2007-2010 period, production from the acquired assets is expected to average more than 75 kboepd. In addition, Eni will further enhance its portfolio in the Gulf of Mexico thanks to new leases with significant exploration potential; approximately 60% of these leases are operated. The transaction is subject to government approvals, 30 days notice to holders of certain preferential rights to purchase (which apply to less than 5% of total reserves), and to other customary conditions precedent. Closing is expected on July 2, 2007. Yukos assets acquisition On April 4, 2007 Eni, through the partnership in EniNeftegaz (60% Eni, 40% Enel SpA) acquired Lot 2 in the Yukos liquidation procedure for a total price of $5.83 billion. Lot 2 includes: 100% of OAO Arctic Gas Company, 100% of ZAO Urengoil Inc and 100% of OAO Neftegaztechnologia. These three companies own 5 gas and condensate fields and parts of other fields in the Yamal Nenets (YNAO) region, the world’s largest gas producing region. Together they have large oil and gas reserves. |  | Eni and Enel have offered Gazprom an option to acquire a 51% interest in these assets within two years. In the event that Gazprom exercises its call option, the assets will be operated through a joint venture between Eni and Gazprom which will have access to Eni’s most advanced technologies. Lot 2 includes also various minor assets that will be sold or liquidated and 20% of OAO Gazprom Neft which will be wholly owned by Eni. Eni offered Gazprom an option to acquire a 20% interest in OAO Gazprom Neft within two years, at a total price of $3.7 billion, in addition to financial expenses related to the acquisition. These agreements are an additional step in implementing the strategic Partnership between Eni and Gazprom signed in November 2006, under which the two companies established an alliance to develop upstream, midstream and downstream energy projects inside and outside of Russia. Acquisition of the retail station network in the Czech Republic, Slovakia and Hungary On April 27, 2007 Eni and ExxonMobil Central Europe Holding GmbH signed an agreement for the sale of shares of Esso spol sro (Esso Czechia), Esso Slovensko spol sro (Esso Slovakia) and ExxonMobil Hungary Kft to Eni. The agreement, subject to the approval of the relevant authorities, includes ExxonMobil's retail station network in the three countries, totaling 102 stations and its aviation business at the Prague and Bratislava airports. Additionally, the lubricants business conducted in these countries by ExxonMobil Petroleum and Chemical, is included in the transaction.

Acquisition of 70% and of the operatorship of the Nikaitchuq Field in Alaska On April 11, 2007 Eni acquired 70% and the operatorship of the Nikaitchuq field, located on-offshore in the North Slope of Alaska. Eni, which already owned a 30% stake in the field, now retains the 100% working interest. Eni acquired the additional interest and operatorship as the result of an agreement with Kerr-McGee Oil and Gas Corporation, a wholly-owned subsidiary of Anadarko Petroleum Corporation. Nikaitchuq would be the first development project operated by Eni in Alaska. Successful appraisal drilling has been completed, confirming the potential viability of the development project. Plans for a phased development are currently being evaluated with the target of sanctioning the project by year end, and first oil to flow by the end of 2009. The Nikaitchuq project comprises the drilling of approximately 80 wells, out of which 32 are located onshore and the remaining from an offshore artificial island. All wells will then be tied back to a production facility located at Oliktok Point to reach a production of 40 kboe/d. Total investment will amount to approximately $900 million. |  | Memorandum of Understanding for the acquisition of an interest in Angola LNG Ltd On April 2, 2007 Eni and Sonangol signed a Memorandum of Understanding for the acquisition of a 13.6% stake in Angola LNG Limited Consortium (A-LNG). This company is responsible for the construction of an LNG plant in Soyo, 300 km North Luanda, with a yearly capacity of 5 mmtonnes. Upon completion of this agreement, Angola LNG Limited’s shareholding structure will be as follows: Sonangol 22.8%, Chevron 36.4%, Eni 13.6%, Total 13.6% and BP 13.6%. The project, for a total investment of approximately $4 billion, has been approved by the Angolan Government and Parliament. It envisages, for 28 years, the development of 220 bcm of gas, the production of 128 mmtonnes of LNG, 104 mmbbl of condensate and 257 mmbbl of LPG. The LNG will be directed to the United States market and will be delivered to the re-gasification plant of Pascagoula, in the Gulf of Mexico, in which Eni, following this agreement, will acquire re-gasification capacity of 5 bcm/y.

ENI REPORT ON THE FIRST QUARTER OF 2007

OUTLOOK FOR 2007

The outlook for Eni in 2007 remains positive, with key business trends for the year as follows: Production of liquids and natural gas is forecast to remain at the same level as 2006 (in 2006 oil and gas production averaged 1.77 mmboe/d). Additional production expected in the second half of the year from acquired properties in the Gulf of Mexico and Congo, and the expected build-up in gas production in Libya will enable Eni to recover the first quarter decline in production due to escalating social unrest in Nigeria and the loss of the Dación oilfield in Venezuela; Sales volumes of natural gas worldwide are expected to increase by 1% over 2006 (actual sales volumes in 2006 were 97.48 bcm). Major increases are expected in certain target markets in the Rest of Europe, mainly in the Iberian Peninsula, the North of Europe, France and Germany/Austria markets; Sales volumes of electricity are expected to slightly increase from 2006 (actual volumes in 2006 were 31.03 TWh); Refining throughputs on Eni’s account are forecast to slightly decrease from 2006 (actual throughputs in 2006 were 38.04 mmtonnes) due to the expiration of a processing contract at the Priolo refinery owned by a third party late in 2006, to be offset by higher throughputs expected at the Gela, Livorno and Taranto refineries; Retail sales of refined products are expected to slightly increase from 2006 (actual volumes sold in 2006 were 12.48 mmtonnes). Increases are expected on both the Italian and European markets due to the entry into service of new outlets, following also the acquisition of service stations in target markets. |  | In 2007 management expects Eni’s capital expenditure on exploration and capital projects to amount to approximately euro 10.5 billion, representing a 34% increase over 2006. Approximately 86% of this capital expenditure programme is expected to be deployed in the Exploration & Production, Gas & Power and Refining & Marketing divisions. Furthermore, acquisitions of assets and interests amounting to euro 9.2 billion are forecast in the year, mainly related to: (i) the already closed transaction for the purchase of ex-Yukos assets; (ii) the other transactions whose closing is foreseen by the end of the year, including the purchase of upstream assets in the Gulf of Mexico and Congo, and a retail station network in the Central-Eastern Europe. Assuming Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni, net cash outflows used in investing activities will decrease to euro 16.2 billion. On the basis of the expected cash outflows for this capital expenditure and acquisition program, and shareholders remuneration, also assuming a $55/barrel scenario for the Brent crude oil, Eni foresees a leverage ranging from 0.3 to 0.4 by the end of the year, depending on the exercise of the above mentioned call options by Gazprom.

Oil and natural gas production in the first quarter 2007 averaged 1,734 kboe/d, a decrease of 93 kboe/d from the same period of the previous year (down 5.1%). This reduction was due primarily to the unilateral cancellation of the Dación field service contract by the Venezuelan state company PDVSA with effect from April 1, 2006 (down 60 kboe/d) and social unrest in Nigeria. Factoring in these effects, oil and natural gas production level was in line with the first quarter 2006. Production increases were achieved mainly in Libya, Kazakhstan and |  | the Gulf of Mexico offsetting mature field declines mainly in Italy and facility shutdown. Daily production of oil and condensates (1,030 kbbl) decreased by 113 kbbl, or 9.9% from the first quarter of 2006. Production decreases were reported mainly in Venezuela and Nigeria due to the above mentioned causes and in the United Kingdom due to a technical problem occurred in the Elgin/Franklin field (Eni’s interest 21.87%) and ordinary maintenance shutdowns at other

facilities. In Italy a few technical problems occurred at the FPSO operating the Aquila field. Main increases were registered in Kazakhstan due to maintenance actions on facilities performed in the first quarter of 2006, and the United States due to the resumption of full activity at plants damaged by hurricanes in the second half of 2005. |  | Daily production of natural gas for the first quarter (4,061 mmcf/d) increased by 141 mmcf, or 3.6% mainly as a result of the build-up of the Bahr Essalam field offshore Libya, full operations at the fifth train of the Bonny LNG plant in Nigeria, a better performance of Norway’s largest fields, and full production of Bayu Undan gas field offshore Australia. Gas production in Italy decreased due to mature field declines.

(a) |  | Starting on January 1, 2007, results from marketing of electricity have been included in results from market and distribution activities following an internal reorganization. As a consequence of this, electricity generation activity conducted by EniPower subsidiary comprises only results from production of electricity. Prior quarter results have not been restated.
(b) |  | Excluding special items.

Results The adjusted operating profit of the Gas & Power division totalled euro 1,683 million, up euro 480 million or 39.9% from the first quarter of 2006, reflecting primarily: (i) increased natural gas selling margins mainly owing to a favorable trading environment reflecting in particular the effect of the euro/dollar exchange rate; (ii) a favorable evolution of the regulatory framework in Italy. This reflected the enactment of Resolution No. 79/2007 by the Authority for Electricity and Gas implementing a new setup of the indexation mechanism of the raw material cost component in supplies to residential and commercial |  | users related to the period from January 1, 2005 to June 30, 2006. Following this, Eni has partially or totally reversed provisions accrued in the accounts for 2005 and the first half of 2006; (iii) the fact that higher purchase costs were incurred in the first quarter of 2006, owing to a climatic emergency for the winter time 2005-2006. These positives were partly offset by a decline in natural gas sales of affiliates (down 2.87 bcm, or 10.4%) due to lower European gas demand as a consequence of the unusually mild weather conditions of the first quarter of 2007, partly offset by a growth in sales in certain target

markets in the Rest of Europe. Lower gas demand negatively affected the operating performance of transport activities in Italy and volumes distributed on low pressure networks. Sales volumes of electricity decreased by 0.12 TWh, or 1.6%. Special charges for the quarter referred to redundancy incentives (euro 2 million). |  | The adjusted net profit was euro 1,159 million up euro 280 million, or 31.9%, reflecting the increased adjusted operating profit, offset in part lower results reported by certain affiliates engaged in natural gas distribution in Italy, due to mild weather conditions.

ENI REPORT ON THE FIRST QUARTER OF 2007

Natural gas sales for the first quarter of 2007 amounted to 28.14 bcm, including own consumption and sales by affiliates and upstream sales in Europe, with a decrease of 3.06 bcm from the first quarter of 2006, or 9.8%. This decline was impacted by lower seasonal gas sales due to an unusually mild winter. In an increasingly competitive market, sales in the Italian market were 15.41 bcm with a decrease of 2.06 bcm, or 11.8%. All market segments posted sale volumes declines from the first quarter of 2006: sales to residential users were down by 0.71 bcm; sales to industrial users were down by 0.47 bcm; sales to wholesalers were down by 0.44 bcm; sales to power generation were down by 0.34 bcm. Sales under the gas release1 program (0.49 bcm) declined by 0.1 bcm. Own consumption (1.38 bcm) declined by 0.08 bcm due to lower supplies to EniPower. Gas sales in the Rest of Europe were 7.9 bcm with a decrease of 0.67 bcm, or 7.8%, due to: (i) lower sales under long-term supply contracts to Italian importers (down 0.75 bcm), despite the full production of natural gas from the Libyan fields; (ii) lower sales in the Hungarian market (down 0.49 bcm). These decreases were partly offset by increases in the supplies to the Turkish (up 0.34 bcm) and Spanish (up 0.18 bcm) markets. |  | Sales of subsidiaries outside Europe (0.1 bcm) declined by 0.06 bcm due to lower supplies to the Argentinean market. Natural gas sales of Eni’s affiliates in the rest of Europe (net to Eni and net of Eni’s supplies) amounted to 2.1 bcm, a 0.23 bcm decline related in particular to: (i) GVS (Eni’s interest 50%) with 0.93 bcm; (ii) Unión Fenosa Gas (Eni’s interest 50%) with 0.57 bcm. Natural gas sales of Eni’s affiliates outside Europe (net to Eni and net of Eni’s supplies) amounted to 0.16 bcm, a 0.23 bcm decline related in particular to Unión Fenosa Gas (Eni’s interest 50%) with 0.13 bcm. Eni transported 23.51 bcm of natural gas in Italy, a decrease of 1.38 bcm from the first quarter of 2006, down 5.5%, due to a decline in domestic demand. Volumes transported on behalf of third parties declined by 0.81 bcm, those transported on behalf of Eni declined by 0.57 bcm. Sales of electricity (7.61 TWh) declined by 0.12 TWh, or 1.6%.

(1) |  | In June 2004 Eni agreed with the Antitrust Authority to sell a total volume of 9.2 billion cubic meters of natural gas (2.3 billion cubic meters/year) in the four thermal years from October 1, 2004 to September 30, 2008 at the Tarvisio entry point into the Italian network.

ENI REPORT ON THE FIRST QUARTER OF 2007

Resolution No. 79/2007 of the Authority for Electricity and Gas “Revision of the economic conditions of supplies in the January 1, 2005 to March 31, 2007 period and criteria for their updating”. Following the cancellation of Resolution No. 248/2004 by the Council of State for formal flaws, on March 29, 2007 the Authority for Electricity and Gas published Resolution No. 79/2007 after concluding a consultation procedure with gas operators. This Resolution organizes in a single document all the changes applied to the determination and updating of economic conditions for natural gas supplies. In particular with this Resolution the Authority: (i) confirmed the indexation mechanism for the raw material cost component contained in Resolution No. 248/2004 and the changes introduced to this mechanism by Resolution No. 134/06 starting on July 1, 2006; (ii) waiving this provision, it reviewed the updating of the raw material cost component for 2005 reaching incremental values equal to those deriving |  | from the application of the indexation criteria of Resolution No. 195/02; this cancels the negative impact of Resolution No. 248/2004 on Eni’s 2005 accounts; (iii) decided that selling companies, only for wholesale purchase/sale contracts entered after January 1, 2005 and valid in the January 1, 2006-June 30, 2006 period, offer their customers new contractual conditions consistent with the new indexation mechanism before June 4, 20072 , and inform the Authority, before June 29, 20072, together with their wholesaler that they have complied with this requirement. Selling companies complying with this requirement will be entitled to 50% of the difference between the updating of the raw material cost component under the new mechanism and the more favorable one under Resolution No. 195/2002 applied to volumes consumed by customers under the 200 kcm threshold. This Resolution determined the total or partial redundancy of liabilities accrued in Eni’s accounts for 2005 and 2006 that have been consequently reversed.

Results The Refining & Marketing division reported an adjusted operating profit of euro 120 million, representing an increase of euro 31 million from the first quarter of 2006, or 34.8%. This increase reflected primarily a better operating performance delivered by the refining activity, which was boosted by higher processed volumes and better yields also in light of lower maintenance shutdowns. The benefit of higher refining margins (margins on Brent crude oil were up 0.11 dollar/bbl, or 3.7%) was more than offset by the negative impact of the euro appreciation over the dollar. Marketing activities in Italy reported a lower operating profit due |  | mainly to lower retail margins and a decline in wholesale volumes as a consequence of lower heating oil demand in Italy, in particular from the power generation sector caused by an unusually mild winter. The adjusted net profit was euro 113 million, up euro 27 million, or 31.4%, due to the improved operating performance. Special charges excluded from the adjusted operating profit for the first quarter of 2007 were euro 18 million, reflecting environmental provisions and provisions for redundancy incentives.

Refining throughputs on Eni’s own account increased by 390 ktonnes from the first quarter of 2006, to 9 mmtonnes, or 4.5%. This increase was due to higher volumes processed at the in Livorno and Venice refineries also reflecting lower maintenance shutdowns, partly offset by the expiration of a processing contract at the Priolo refinery owned by a third party and lower throughputs at the Gela and Taranto refineries due to planned maintenance shutdowns. The wholly-owned refineries throughputs increased by 0.81 mmtonnes from the first quarter of 2006, to 6.67 mmtonnes, or 13.8%, mainly in the Livorno, Taranto and Porto Marghera refineries. The wholly-owned refinery utilization rate was 100% based on utilization rates of refinery balanced capacity. Sales of refined products increased by 20 ktonnes from the first quarter of 2006, to 12.34 mmtonnes, or 0.2%, due to: (i) higher volumes sold to oil companies and traders in Italy, partly offset by lower volumes sold to the petrochemical sector reflecting the expiration of a processing contract at the Priolo refinery (overall up 350 ktonnes); and (ii) higher sales on both the retail and wholesale markets in the Rest of Europe (up 50 ktonnes). These positives were partly offset by a decline in both the retail and wholesale markets in Italy (down 410 ktonnes) due to the impact of mild weather in the first quarter 2007 and competitive pressure. |  | Sales of refined products on the retail market in Italy decreased by 80 ktonnes from the first quarter of 2006, to 1.98 mmtonnes, or 3.9%, primarily due to competitive pressure and lower demand. Retail market share in Italy declined by 1 percentage point from 29.3% in the first quarter of 2006 to 28.3%. Average throughput (0.56 mmliters in the first quarter of 2007) declined by approximately 20 kliters from the same period in 2006. Sales on the retail market in the Rest of Europe increased by 30 ktonnes from the first quarter of 2006, to 0.9 mmtonnes, or 3.4%, mainly in Spain. Market share outside Italy grew slightly from 3.1% in the first quarter of 2006 to 3.2% in the first quarter of 2007. Average throughput (0.58 mmliters in the first quarter of 2007) increased by approximately 20 kliters from the same period in 2006. Sales on wholesale markets in Italy decreased by 330 ktonnes from the first quarter of 2006, to 2.61 mmtonnes, due to lower demand for heating products in particular from the power generation sector caused by unusually milder weather. Sales on wholesale markets in the Rest of Europe increased by 20 ktonnes, to 1.05 mmtonnes, primarily reflecting the increase in sales in the Czech Republic.

Results Adjusted operating profit in the first quarter of 2007 amounted to euro 122 million increasing by euro 99 million from the first quarter of 2006 due mainly to higher selling margins, essentially the cracker margin and to a lower extent the aromatics business. |  | Special charges in the first quarter concerned essentially redundancy incentives.

Sales of petrochemical products (1,417 ktonnes) were stable from the first quarter of 2006, due essentially to higher sales of (i) olefins (up 8.1%) due to higher availability of ethylene (up 15.2%) and polypropylene (up 5.5%) due to the purchase by Syndial of the Porto Torres plant; (ii) styrene (up 4.7%) due to a positive demand, in particular for ABS/SAN (up 100%). Declines concerned: (i) intermediates (down 8.4%) due to lower product availability, in particular cycloexanone (down 17.5%) and acetone (down 11.9%); (ii) aromatics (down 4.8%) related in particular to xylene (down 13.3%), due to a different setup of the Priolo plant |  | following the accident occurred in the nearby refinery in the second quarter of 2006; (iii) polyethylene (down 4.6%) due to lower LDPE (down 7.3%) and LLDPE (down 6.3%) sales due to an unusually high demand in the first months of 2006 resulting from the build-up of inventories. Petrochemical production (2,227 ktonnes) increased by 312 ktonnes from the first quarter of 2006, up 16.3% due to the consolidation of operations at Porto Torres (up 282 ktonnes). Excluding this effect production increased by 30 ktonnes (up 2%) due in particular to the growth registered at the Sarroch, Ravenna and Brindisi plants.

Adjusted net loss of euro 86 million increased by euro 92 million from the first quarter of 2006 due to losses recognized on the fair value evaluation of certain financial derivatives instruments recorded in the profit and loss account instead of being recognized in connection with related assets, liabilities and commitments |  | because these instruments do not meet the formal criteria to be assessed as contracts hedges under IFRS including the time value component. This negative was partly offset by a lower operating loss (down euro 11 million).

ENI REPORT ON THE FIRST QUARTER OF 2007

Non-GAAP measures

RECONCILIATION OF REPORTED OPERATING PROFIT AND NET PROFIT TO RESULTS ON AN ADJUSTED BASIS

Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Further, finance charges on finance debt, interest income, charges or income deriving from the fair value evaluation of derivative financial instruments held for trading purposes, and exchange rate differences are excluded when determining adjusted net profit of each business segment. The taxation effect of such items excluded from adjusted net profit is determined based on the specific rate of taxes applicable to each item, with the exception of finance charges or income, to which the Italian statutory tax rate of 33% is applied. Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them to facilitate comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment. The following is a description of items which are excluded from the calculation of adjusted results. Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting. Special items include certain relevant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items |  | under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write-ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non-recurring material income or charges are to be clearly reported in the management’s discussion and financial tables. Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition, gains or losses on the fair value evaluation of derivative financial instruments held for trading purposes and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivables financing and securities related to operations and finance charges pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production division). Finance charges or interest income and related taxation effects excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies. For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and reported net profit see tables below.

ENI ANNUAL REPORT / PROFILE OF THE YEAR

Profile of the year |  |
Results In 2006 Eni delivered record earnings, up 4.9% from 2005 to euro 9.2 billion; on an adjusted base, earnings were up 12.5% to euro 10.4 billion. This result was driven by continued improvements in performance and consistent execution of Eni’s strategy, in a broadly favorable trading environment. Total Shareholder Return for the year came in at 14.8%, one of the highest in the industry. Dividend 2006 record earnings and cash flow, along with a sound balance sheet structure, allow a dividend distribution of euro 1.25 per share, up 13.6% from 2005 (euro 1.10 per share in 2005). Included in this annual payment is euro 0.60 per share already distributed as interim dividend in October 2006. Pay-out stands at 50%. |  | Oil and natural gas production Oil and natural gas production for the year averaged 1.77 mmboe/d, up 1.9% compared with 2005. This included the loss of production at the Venezuelan Dación oilfield (down 46 kbbl/d) and lower entitlements in certain Production Sharing Agreements (PSAs) and buy-back contracts (down 21 kbbl/d) due to higher oil and gas prices. Eni delivered its 3% production growth rate based on a $55 per barrel scenario, as announced in the 2006 quarterly production outlook. Libya, Angola and Egypt were the main growth areas. Proved oil and natural gas reserves Net proved reserves at December 31, 2006 stood at 6.44 bboe (down 6% compared with December 31, 2005), representing 10 years of remaining production at the current rate. Organic proved additions, as calculated by applying a year-end Brent price of $58.93 per barrel, replaced 65% of production. Assuming Brent is constant at $40 per barrel when determining entitlements in PSAs, the three-year average proved reserve replacement ratio would be 106%.

ENI ANNUAL REPORT / PROFILE OF THE YEAR

Natural gas sales Natural gas sales were up approximately 4% to 97.48 bcm due primarily to the growth in sales in a number of target European markets (up approximately 16% in particular in Turkey, Germany/Austria and France) also for the build-up of supplies of natural gas from Libya, partly offset by a decrease in sales in Italy due to mild weather conditions in the fourth quarter of the year. Sales of liquefied natural gas (LNG) were 9.9 bcm, up 41.4% from 2005. Strategic agreement with Gazprom In November 2006, Eni and Gazprom signed a broad strategic agreement. This alliance sets up a long term partnership enabling the two companies to launch joint projects in the mid- and downstream gas sector, in the upstream and in technological cooperation. A key feature of this deal is the extension of the duration of Russian gas supply contracts until 2035, further strengthening Eni’s supply portfolio. |  | Expansion strategy: purchase of oil producing and exploratory assets in Congo In February 2007, Eni defined a deal with the French company Maurel & Prom to acquire producing assets and exploration licenses located onshore in Congo, entailing a cash consideration of $1.4 billion. The deal is consistent with Eni’s strategy of purchasing proved and unproved reserves and producing assets in legacy countries where Eni can achieve synergies leveraging on its competencies and the availability of facilities. This transaction is subject to approval by the Congolese authorities. Exploration activity In 2006, Eni invested euro 1,348 million in exploratory activities, up 106% from 2005, executing a huge exploration campaign leading to the completion of 68 exploratory wells (36 net to Eni) with a commercial rate of success of 43% (49% net to Eni). A further 26 wells were in progress as of the year-end. Eni enhanced its exploration portfolio by acquiring assets in core areas such as North Africa, West Africa, Brazil, Norway and the United States, and in new high-potential basins such as Mali, Mozambique and East Timor. New acreage covers 152,000 square kilometers (99% operated by Eni).

ENI ANNUAL REPORT / LETTER TO SHAREHOLDERS

Eni’s Board of Directors

|  | Roberto Poli Chairman |  | Paolo Scaroni CEO

To our Shareholders 2006 was a remarkable year for Eni in terms of both financial performance and operational accomplishments Our earnings and cash flow were the highest in our history, driven by continued improvements in performance and consistent execution of our strategy in a broadly favourable trading environment. In particular, we maintained pleasing production growth despite the impact of disruption in Venezuela, achieved several exploration successes, secured access to promising new acreage and further expanded our global natural gas business. On top of that, we struck a landmark agreement with Gazprom which extends our gas contracts to 2035 and opens up new opportunities for upstream expansion in Russia. Financial performance Our reported net profit of euro 9.2 billion in 2006 was the highest in the history of the Company. Adjusted net profit rose 12.5% to euro 10.4 billion, representing a return on average capital employed of 22.7%. Net cash generated by operating activities totalled euro 17 billion, allowing us to finance capital expenditure of euro 7.8 billion and to reduce our debt/equity ratio to 0.16. Those strong results enabled us to propose a dividend of euro 1.25 per share to our Annual General Shareholders’ Meeting, up 14% |  | compared to 2005 (euro 1.10 per share), of which euro 0.60 was paid as an interim dividend in October 2006. During the year, we purchased a total of 53.1 million of our own shares for euro 1.2 billion, bringing the total cash returned to shareholders for the year to euro 5.8 billion. Our total shareholder return was 14.8%, making this the fifth year running that we have outperformed our peer group. Sustaining growth and shareholder return Growth is at the heart of our strategic priorities. A strong pipeline of projects and investment opportunities will enable us to achieve our ambitious short and long-term growth targets. Over the next four years, we will invest euro 44.6 billion in our businesses to ensure our continued growth, also beyond 2010. This investment program, the largest ever in Eni’s history, will be carried out with tight financial discipline. The projected free cash flow in 2010 will allow us to sustain the current flow of dividends in real terms, even with a scenario of 40$/bl Brent. Among Eni’s business divisions, EXPLORATION & PRODUCTION showed the strongest growth. In 2006, the division’s adjusted net profit increased by 17.7% to euro 7.3 billion. Oil and gas production rose by approximately 2% to 1.77 million boepd. This increase was entirely organic and was achieved despite the negative impact of the unilateral

termination of the Dación contract in Venezuela and the adverse entitlement effects in PSAs and buyback contracts due to higher oil prices. Excluding the effect of higher oil prices on PSAs and the termination of the Dación contract, organic production growth was close to an impressive 6%. We are committed to maintaining strong organic production growth. The company targets a production level of 2 million boepd by 2010, with an average growth rate of approximately 3% per year. Exploration activity reaped substantial results in 2006, reaching an average success rate of 49% and adding 152,000 sq km of net acreage, 99% operated. Over the medium term, we are committed to replacing more than 100% of produced reserves. Development activities are progressing in many fields around the world, including Kashagan, where we expect higher capex and a longer timetable. However, we have also been able to confirm that the field is capable of higher production levels than previously thought. We are progressing with the global expansion of the LNG business as a way to monetize our large gas reserve base. Major steps taken in 2006 include the start-up of train five at the Bonny liquefaction plant in Nigeria, where a sixth train will commence operations in 2008, and the signing of a framework agreement for doubling the capacity of the Damietta liquefaction plant in Egypt by 2010. |  | The growth options we are presently pursuing with our partner Gazprom could potentially enable us to accelerate the achievement of our growth targets. In GAS & POWER, our strong and integrated position in Europe generates stable and robust earnings and cash flows. Adjusted net profit for the year rose by 12.1% to euro 2.9 billion, supported by an approximately 16% increase in volumes sold in Europe (excluding Italy) to 35 bcm (excluding gas sold by E&P of 4 bcm). This result was achieved despite stiff competition and mild weather. Our strategy is based on growing our market share in key European markets, preserving our domestic natural gas business and effectively managing our regulated business. European natural gas demand is forecast to grow steadily in the future, resulting in a cumulative increase of around 45% by 2020 (2.4% per annum). This, coupled with the decline of Europe’s internal production, means that our continent will become more and more reliant on external supplies to fulfil its gas needs. In this context, Eni is poised to further strengthen its market leadership by leveraging on an unparalleled portfolio of assets in terms of infrastructure, availability of gas – both equity and purchased under long term supply contracts – long-standing relationships with natural gas producing countries, market knowledge and a large customer base. The recent alliance with Gazprom marks a new milestone in our relationship with the largest natural

gas producer in the world, and will enable us to reinforce our competitive profile. By 2010 we are committed to selling more than 105 bcm of gas worldwide, with sales outside Italy expected to grow at an average rate of 10% per year. Our REFINING & MARKETING division reported an adjusted net profit of euro 629 million, which was 33.4% lower than in 2005 due to the weak refining margin environment, the appreciation of the euro against the dollar and the impact of higher levels of planned maintenance activity. Looking forward, several trends are emerging in the refining landscape: the adoption of increasingly strict environmental standards, global imbalances in product availability (especially a deficit of diesel fuel in Europe), a relative abundance of heavy crude and the desire to increase efficiency. These are the key drivers of our strategy. In Refining, Eni will increase its capital expenditure to enhance the refinery conversion rate in order to meet future product quality requirements, produce higher-value products and chemical feedstocks, lower operating costs and increase refinery flexibility in processing low-quality crude oils. In Marketing, we aim to extract full value from our retail business in Italy through a selective investment program, customer-focused marketing initiatives, effective differentiation of pricing, an improved premium-products offer, and operating efficiencies. |  | In managing our PETROCHEMICAL operations, which reported an adjusted net profit of euro 174 million for 2006, we remain committed to improving efficiency and selectively developing those plants with sufficient scale and a favourable geographic location. Capital expenditure will be focussed on implementing de-bottlenecking projects, enhancing the efficiency and flexibility of plants in areas of excellence (styrenes and elastomers) and maintaining high standards of health, safety, security and environmental performance. In ENGINEERING & CONSTRUCTION, adjusted net profit rose by 22% to euro 400 million, reflecting the strong competitive position held by Saipem, also as a result of the integration of Snamprogetti. To cope with rising demand for drilling equipment and oilfield services, Saipem is planning to further expand the geographical reach and operational features of its world-class fleet. Our relentless commitment to technological research and innovation underscores a fundamental belief that technology is key to increasing our competitive advantage over the long term and promoting sustainable growth. We are conducting research aimed primarily at reducing the costs of finding and recovering hydrocarbons, upgrading heavy oils, monetizing stranded gas and protecting the environment. In particular we are moving forward on our breakthrough technologies: EST (Eni Slurry Technology) for the full exploitation of the heavy barrel, TAP (gas transportation at high pressure) and GTL (gas-to-liquids) for gas monetization.

ENI ANNUAL REPORT / LETTER TO SHAREHOLDERS

Sustainable development 2006 marks the first year in which Eni has published a Sustainability Report to communicate more effectively with stakeholders. We now have a more coherent approach to sustainability, and are even more committed to managing and developing your company in a responsible and accountable way. Among the various initiatives, our focus is on reducing greenhouse |  | gas emissions from industrial processes and developing projects to economically exploit flared gas. In conclusion, 2006 was a very good year for Eni. As well as delivering impressive results, we have worked to create future growth opportunities in all our divisions. We are confident that we can continue to deliver industry-leading growth and superior shareholder returns.

ENI ANNUAL REPORT / OPERATING REVIEW

Acquisition of operated assets in Congo
› On February 2007, Eni purchased exploration and production onshore activities operated by Maurel & Prom in Congo, entailing a cash consideration of $1.4 billion. This deal is consistent with Eni’s strategy of purchasing proved and unproved reserves and producing assets in legacy countries where Eni can achieve synergies leveraging on own competencies and the availability of facilities. This transaction is subject to approval by the Congolese authorities

Financial results
› Adjusted net profit was euro 7,279 million, up euro 1,093 million from a year ago (+17.7%), reflecting an enhanced operating profit as a result of higher oil and natural gas realization in dollars combined with increased production volumes sold. These positives were offset in part by higher operating costs and a higher adjusted tax rate

› Return on average capital employed calculated on an adjusted basis was 37.5% in 2006, higher that in 2005 (32.4%)

› In 2006, price differentials between equity realizations and the price of the Brent crude marker were equal to minus $3.63 per barrel, improving from 2005 levels, as a result of appreciation on the market of oil produced in Angola and higher realizations recorded on Kazakh oil. Natural gas prices increased in virtually all areas, reflecting higher prices for oil and products

› Eni invested euro 3.6 billion in the development of oil and natural gas reserves, in particular in Kazakhstan, Angola, Egypt and Italy, and euro 1.4 billion (up 106% compared with 2005) in exploration activities, in particular in Angola, Egypt, Nigeria, the Norwegian offshore and the Gulf of Mexico

Production
› Oil and natural gas production for the year averaged 1.77 mmboe/d, up 1.9% from 2005. This included the loss of production at the Venezuelan Dación oilfield and lower entitlements in certain Production Sharing Agreements (PSAs) and buy-back contracts1 due to higher oil and gas prices. Eni delivered its 3% production growth rate based on a $55 per barrel scenario, as announced in the 2006 quarterly production outlook

› Production increases were driven primarily by start-ups/full production of large gas projects in Libya (achievement of full production at the Bahr Essalam field in the Western Libyan Gas Project), Nigeria (start-up of trains 4 and 5 of the Bonny LNG plant), Egypt (development of offshore reserves in the Nile Delta), Australia (start-up of the gas phase of the Bayu-Undan field), Croatia (start-up of the Ika, Ida and Ivana C-K fields) and liquid production growth in Angola and Libya

› In the medium term, Eni expects to deliver a 3% compound average growth rate from 2007 to 2010, targeting a production level in excess of 2 mmboe/d by 2010

Organic proved additions, as calculated by applying a year-end Brent price of $58.93 per barrel, replaced 65% of production. Assuming Brent is constant at $40 per barrel when determining entitlements in PSAs, the three-year average proved reserve replacement ratio would be 106%

› In the medium term, management expects Eni’ s reserve replacement ratio to be supported by the high mineral potential of assets located in core areas such as the Caspian Sea, West and North Africa

Exploration activities and renewal of mineral right portfolio
› Eni carried out several hydrocarbon discoveries, mainly in Indonesia, Egypt, Kazakhstan, Norway, Nigeria, United Kingdom, the Gulf of Mexico, Italy, Angola and Congo. A total of 68 exploratory wells were completed (35.9% net to Eni), with a commercial rate of success of 43% (49% net to Eni). Other 26 wells are in progress as of year-end

› Eni’s exploration portfolio was strengthened through acquisition of assets in both core areas such as Angola, Alaska, Brazil, Congo, Egypt, Nigeria, Norway, Pakistan, the Gulf of Mexico and new countries/areas with a high mineral potential such as Mali, Mozambique and East Timor. Gross acquired acreage extends for approximately 259,000 square kilometers (152,000 net to Eni, 99% operated)

Reserves Reserve Governance The Company has adopted comprehensive classification criteria for proved, proved developed and proved undeveloped oil and gas reserves in accordance with applicable U.S. Securities and Exchange Commission (SEC) regulations, as provided for in Regulation S-X, Rule 4-10. Proved oil and gas reserves are the estimated quantities that geologic and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions. Engineering estimates of the Company’s oil and gas reserves are inherently uncertain. Although authoritative guidelines exist regarding engineering criteria that have to be met before estimated oil and gas reserves can be designated as “proved”, the accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgment. Consequently, the estimated proved reserves of oil and natural gas may be subject to future revision and upward and downward revisions may be made to the initial booking of reserves |  | due to analysis of new information concerning production, reservoir performance, commercial factors, acquisition and divestment activity and additional reservoir development activity. Field resources will only be categorized as proved reserves when all criteria for the attribution of proved status has been met, including technical, economic and commercial criteria. Proved reserves to which Eni is entitled under concession contracts are determined by applying Eni’s share of production to total proved reserves of the contractual area, in respect of the duration of the relevant mineral right that normally coincides with the duration over which a field can be produced economically. Proved reserves to which Eni is entitled under Production Sharing Agreements or buy-back contracts are calculated so that the sale of production entitlements should cover expenses incurred by the Group to develop a field (cost oil) and on the profit oil set contractually. A similar scheme applies to buy-back and service contracts. In a high oil price environment, the volume of entitlements necessary to cover the same amount of expenses is lower. Eni has always exercised rigorous control over the booking process of proved reserves. The Reserve

ENI ANNUAL REPORT / OPERATING REVIEW

Department of the Exploration & Production division, reporting directly to the General Manager, is entrusted with the task of continuously updating the Company’s guidelines concerning reserve evaluation and monitoring the periodic quantification process. Company guidelines have been reviewed by DeGolyer and MacNaughton (D&M), an independent petroleum engineers company which has declared their compliance with applicable SEC rules. D&M has also stated that the company guidelines regulate situations for which the SEC rules are less precise, providing a reasonable interpretation in line with the generally accepted practices in international markets. Eni estimates its proved reserves on the basis of the mentioned guidelines, also when participating in |  | exploration and production activities operated by other entities. The process for evaluating reserves involves: (i) business unit managers (geographic units) and Local Reserve Evaluators (LRE), who perform the evaluation and classification of technical reserves (production profiles, capital expenditure, operating costs and costs related to asset retirement obligations); (ii) geographic area managers at head offices checking evaluations carried out by business unit managers; (iii) the Reserve Department, providing independent reviews of the fairness and correctness of classifications carried out by business units, who also aggregates worldwide reserve data and calculates equity volumes. Moreover, the Reserve Department has the following responsibilities: to ensure the periodic certification
process of reserves, to perform economic evaluation of reserves and to continuously update the Company guidelines on reserves evaluation and classification. All personnel involved in the process of reserve evaluation are knowledgeable on SEC guidelines for proved reserves classification and have professional abilities adequate to the complexity of the task, expressing their judgment independently and respectful of professional ethics. Since 1991, Eni has employed qualified independent petroleum engineers companies to perform independent evaluations2 of its proved reserves on a |  | rotational basis. In particular, in 2006, a total of 1.4 billion boe of proved reserves was evaluated, representing 21% of Eni’s total proved reserves at December 31, 2006. Outcomes of these independent evaluations confirmed Eni’s evaluations, as they did in previous years. During the 2004-2006 three year period, independent evaluations covered 76% of Eni’s total proved reserves. Further information on reserves is provided in Note 35 to Eni consolidated financial statements – “Supplemental oil and gas information for the exploration and production activities – Oil and natural gas reserves”.

Algeria: Drilling unit

Evolution of proved reserves Eni’s net proved reserves of oil and natural gas at December 31, 2006 totaled 6,436 mmboe (oil and condensates 3,481 mmbbl; natural gas 2,955 mmboe). These reserves are located in Italy (12% of Eni’s total proved reserves); North Africa (32%; in particular in Libya, Egypt and Algeria); West Africa (17%; in particular in Nigeria and Angola); the North Sea (11%; Norway and the United Kingdom) and Rest of World (28%; in particular in Kazakhstan, Pakistan, Australia and Ecuador). At December 31, 2006, proved reserves associated with PSAs represented 53% of total proved reserves (48% as at December 31, 2005). Proved reserves associated with service and buy-back contracts represented 2% of all proved reserves at December 31, 2006 (2% at December 31, 2005). Additions to proved reserves booked in 2006 were 417 mmboe deriving from: (i) extensions and discoveries (161 mmboe), in particular in Kazakhstan, Algeria, |  | Egypt, Trinidad & Tobago and Libya; (ii) improved recovery (105 mmboe), in particular in Egypt, Angola, Algeria, Kazakhstan and Nigeria; (iii) revisions of previous estimates (up 151 mmboe) related to upward revisions registered in Kazakhstan, Libya and Egypt, offset in part by downward revisions in Nigeria and Ecuador. The unilateral cancellation of the service contract for the Dación oilfield by the Venezuelan state oil company PDVSA determined a decrease in Eni’s proved reserves of 170 mmbbl (see Venezuela below). In 2006 Eni’s proved reserves replacement ratio was 65% (38% all sources, including the loss of proved reserves at the Venezuelan Dación oilfield and other disposals) representing 10 years of remaining production at the current rate (10.8 as at December 31, 2005). Considering the adverse entitlement impact in certain PSAs and buy-back contracts resulting from higher oil prices (Brent price was $58.925 per barrel at December 31, 2005) and assuming Brent constant at

$40 per barrel when determining entitlements in PSAs, the three-year average proved reserve replacement ratio would be 106%. At December 31, 2006, Eni’s proved developed reserves stood at 4,059 mmboe (oil and condensates 2,144 mmbbl, natural gas 1,915 mmboe) or 63% of total proved reserves (63% at December 31, 2005). |  | Mineral right portfolio and exploration activities As of December 31, 2006, Eni’s mineral right portfolio consisted of 1,029 exclusive or shared rights for exploration and development in 36 countries on five continents for a total net acreage of 385,219 square kilometers (266,000 at December 31, 2005). Of these, 48,273 square kilometers concerned production and development (55,098 at December 31, 2005). Outside Italy net acreage (362,723 square kilometers) increased by 120,775 square kilometers mainly due to the acquisition of assets after international bid procedures in Angola, Australia, Brazil, Congo, Egypt, Morocco, Nigeria, Norway, Pakistan and the United States, as well as in the new countries/areas of Mali, Mozambique and East Timor. In Italy, net acreage (22,496 square kilometers) declined by 1,557 square kilometers due to releases. In 2006, a total of 68 new exploratory wells were drilled (35.9 of which represented Eni’s share), as compared to 52 exploratory wells completed in 2005 (21.8 of which represented Eni’s share). Overall commercial success rate was 43% (49% net to Eni) as compared to 39.3% (47.4% net to Eni) in 2005.

ENI ANNUAL REPORT / OPERATING REVIEW

Production In 2006 oil and gas production averaged 1,770 kboe/d, up 32 kboe from 2005 or 1.9%, despite the impact of the production loss in the Dación oil field in Venezuela (down 46 kboe/d) and of adverse entitlement effects (down 21 kboe/d) in PSAs and buy-back contracts due to higher oil prices. Libya, Egypt, Nigeria, Australia and Croatia were the main growth areas in natural gas, while oil production increased in Angola and Libya. Declines in production were attributable to mature fields and technical problems in Nigeria due to social |  | unrest. Production outside Italy covered 87% of the total (85% in 2005). Daily oil and condensates production for the year (1,079 kbbl/d) increased mainly in: (i) Angola due to the production ramp-up at the Kissanje and Dikanza fields in Phase B of the development of Kizomba in Block 15 (Eni's interest 20%) and the start-up of the Benguela/Belize/Lobito/Tomboco fields in Block 14 (Eni's interest 20%); (ii) Libya, due to the ramp-up of the Bahr Essalam offshore field (Eni's interest 50%) as part of the Western Libyan Gas Project and the El Feel

field (Eni's interest 23.3%). Production decreased in Venezuela, Nigeria, despite obtaining full production at the Bonga field in OML 118 permit (Eni's interest 12.5%) and Italy due to technical problems occurred at the FPSO unit in the Aquila field and to production declines of mature fields. Daily production of natural gas for the year (3,962 mmcf/d) increased mainly in: (i) Libya, due to the reaching of full production at the Bahr Essalam offshore field (Eni's interest 50%); (ii) Egypt, for full production/start-up of the Barboni, Baltim North, and Anshuga fields and the increase in the number of production wells at the el Temsah 4 platform in the offshore of the Nile Delta and increased supplies to the Damietta liquefaction plant (Eni's interest 40%); (iii) Nigeria, due to increased supplies to the Bonny LNG plant (Eni's interest 10.4%) related to the start-up of trains 4 and 5; (iv) Australia, due to the start-up of supplies to the Darwin liquefaction plant linked to the Bayu Undan liquid and gas field (Eni's interest 12.04%); (v) Croatia, due to the start-up of the Ika, Ida and Ivana C-K fields (Eni's interest 50%) in the Adriatic offshore. These increases were offset in part by a decline registered in Italy resulting from the production decline of mature fields. Oil and gas production sold amounted to 625.1 mmboe. The 20.8 mmboe difference over production (645.9 mmboe) reflected volumes of gas consumed in operations (18.4 mmboe). Approximately 68% of oil and condensate production sold (391.1 mmbbl) was destined to Eni’s Refining & Marketing segment; 40% of natural gas production sold (1,346 bcf) was destined to Eni’s Gas & Power segment. Main exploration and development projects NORTH AFRICA Algeria Main discoveries for the year were: a) in onshore Block 403a (Eni’s interest 100%), the appraisal wells Rom N2 and N3 found oil at a depth of about 3,300 meters; b) in onshore Block 404a (Eni’s interest 25%), the BBKS-1 discovery well showed the presence of oil at a depth of 3,160 meters which yielded 700 barrels/d in test production; the appraisal well BBKSE-1 showed the presence of oil at a depth of about 3,200 meters and confirmed the eastward extension of the BBKS structure. The main ongoing development projects are: (i) the ROM flaring down project (Eni’s interest 100%), targeting a 90% decrease in current volumes of flared gas at the ROM satellite center, in accordance with |  |

Algerian law; (ii) the ROM and ZEA Integrated Development project (Eni’s interest 100% and 75%, respectively), aiming at developing reserves recently confirmed by the appraisal work by means of water re-injection to support pressure in field. Peak production is expected at 21 kbbl/d (12 net to Eni) in 2010; (iii) El Merk Synergy project with start-up expected in 2010. Leveraging on synergies with the development of reserves in Block 208, 212, 405a and 404, the project provides for the construction of a central facility which will produce stabilized oil, condensates and NGL with an initial level of production at 144 kboe/d (19 net to Eni) in 2010. In 2006, 85% of basic engineering work was completed. Algeria is currently reviewing the fiscal regime applicable to oil companies. With regard to the legislative text already enacted, fiscal terms applicable to existing PSAs to which foreign oil companies are parties have not been directly modified. Nevertheless, Sonatrach, the State oil company is currently bearing higher taxation on behalf of foreign oil companies. On this basis, Sonatrach intends to renegotiate the economic terms of certain PSAs to which Eni or other Eni co-venture partners are party. According to Sonatrach, renegotiation of contractual terms is necessary in order to restore the initial economics of such contracts. At present, management is not able to foresee the final outcome of such renegotiations. In addition, the Algerian parliament with the Decree No. 06-440 of December 2, 2006 enacted the procedure, the application framework and the calculation methodology of a windfall tax charged to foreign oil companies as approved by the local Government. Effective August 1, 2006, said windfall tax applies to the extent that oil prices exceed $30 per |  | barrel and foresees rates ranging from 5 to 50% depending on the share of production to which a foreign company is entitled and the contractual scheme in force with Sonatrach. In 2006, the application of such tax entailed higher current taxation and a deferred tax charge for a total of euro 328 million impacting Eni’s accounts. Egypt Main discoveries for the year were in: a) offshore Abu Rudeis permit (Eni’s interest 100%) the Abu Rudeis Marine 4 discovery well showing the presence of liquids at a depth of over 3,000 meters; the well was linked to existing production facilities; b) onshore West Razzak permit (Eni’s interest 80%) the Aghar SW-1X discovery well showed the presence of high quality liquids at a various levels at a depth between 1,800 and 2,300 meters; c) offshore West Baltim permit (Eni’s interest 100%) the Meret 1 and 2 discovery wells showed the presence of natural gas and condensates at various levels at depth between 1,500 and over 3,000 meters; d) offshore Thekah permit (Eni 50%) the Thekah North 1 discovery well showed the presence of natural gas at a depth between 1,350 and 1,650 meters; the well was linked to existing production facilities; e) onshore Meleiha permit (Eni’s interest 56%) the Lotus North 1-X discovery well showed the presence of oil at a depth of over 2,000 meters and has started to produce. The Nada Ne 1-X discovery well showed the presence of oil and natural gas at a depth of 1,900 meters in the same area and has started to produce. Development activities are underway in the offshore area of the Nile Delta: (i) in the North Port Said concession (Eni’s interest 100%), the Anshuga gas field was linked to the production facilities of the nearby Nouras field by means of a sea line, starting production

Exploration plans envisage the drilling of a well in the first three years of the license. In September 2006, Eni purchased further interests in two exploration licenses off the coast of Norway: (i) in the Prospecting License 221 (Eni’s interest 30%) where the Victoria gas discovery is located, representing a technological challenge due to the high pressure and |  | high temperature conditions of the reservoir; (ii) in the Prospecting License 264 (Eni’s interest 40%) where the Hvitveis gas discovery is located. In January 2007, following an international bid procedure, Eni was awarded offshore Block 6506/9-6507/7 (Eni’s interest 30%). Ongoing development activities are focused primarily on hydrocarbon bearing structures located near the Kristin field (Eni’s interest 8.25%). Development of the Tyrihans field (Eni’s interest 6.23%) is expected to be profitable through synergies with the Kristin production facilities. In July, the development plan was sanctioned; relevant contracts for building infrastructure and production facilities are being awarded. Production is expected to start in 2009, in coincidence with the expected production decline of Kristin which will make spare capacity available to process production from Tyrihans. United Kingdom Main discoveries for the year were in: a) the P/011 permit in Block 30/06a (Eni’s interest 33%) in the central section of the North Sea an appraisal well was drilled at a depth between 4,500 and 5,100 meters confirming the presence of hydrocarbons; b) the P/672 permit in Block 30/02c (Eni’s interest 7%) in the central section of the North Sea, a discovery of a natural gas and condensate bearing layer was made at a depth of 5,000 meters; this well was linked to the production facilities of the nearby Jade field (Eni’s interest 7%).

United States (Gulf of Mexico): The Allegheny production platform Production at 12 kboe/d (2.2 net to Eni) is expected to start in the first half of 2007. REST OF WORLD Australia In offshore Block WA-25-L (Eni operator with a 65% interest), the Woollybutt-5 appraisal well confirmed the presence of oil at a depth of 2,865 meters. In June 2006, development started at the offshore Blacktip gas and liquids field (Eni’s interest 100%) located in the WA-279-P Block at a water depth of 50 meters in the Bonaparte basin, south of the Australian coast. This project envisages the installation of a production platform approximately 100 kilometers from the mainland and construction of an onshore treatment plant with a capacity of 46 bcf/y. Start-up is expected in January 2009. Under a 25-year agreement signed with the Darwin Power & Water Utility Co, a total amount of 706 bcf of natural gas is expected to be supplied with an option for further volume increases. In February 2006, the first shipment of LNG was delivered to two Japanese operators from the Darwin liquefaction plant with a capacity of 3.5 mmtonnes/y of LNG (equivalent to approximately 173 bcf/y of natural gas). This plant is linked by means of a 500-kilometer long pipeline to the liquids and gas Bayu Undan field located at a water depth of 80 meters in permits JPDA 03-12 and JPDA 03-13 in the waters of the international cooperation zone between Australia and East Timor (Eni’s interest 12.04%). Brazil In January 2006, following an international bid procedure, Eni was awarded a six-year exploration license in Block BM Cal-14, acting as operator. Gross acreage extends over approximately 700 square kilometers in the deep waters of the Camamu-Almada basin. In November 2006, following an international bid, |  | Eni was awarded offshore Block S-M-857 (Eni’s interest 100%), covering a gross acreage of 700 square kilometers, in the deep waters of the Santos basin. The assignation of blocks has not yet been completed. Croatia In the offshore Ivana concession (Eni’s interest 50%) the Ana 1 and Vesna 1 discovery wells identified the presence of natural gas at a depth between 650 and 1,200 meters. Ivana C/K platforms and Ika and Ida fields started production as part of the development of the natural gas reserves of the Ivana concession. Production from these fields is gathered at the Ivana K platform from which is sent to the Garibaldi K platform to be sold on the Italian market, through a 67-kilometer long pipeline. Production from these four fields is currently flowing at 152 mmcf/d (49 net to Eni). At the end of 2006, production at the Katarina field started by means of two platforms linked to existing transport facilities. East Timor In May 2006 following an international bid procedure Eni was awarded the operatorship of five exploration licenses (Eni’s interest 100%) covering contract areas A, B, C, E and H with a gross acreage of about 12,183 square kilometers located in the deep offshore between the Timor island and the international cooperation zone between East Timor and Australia. Relevant Production Sharing contracts were signed. Kazakhstan Eni is single operator with an 18.52% interest of the North Caspian Sea PSA. Such contract regulates activity in the relevant contractual area where the Kashagan field was discovered, which is deemed to be the most important discovery in the world in the past thirty years. The development plan of this field was sanctioned in February 2004, entailing a three-phase development scheme to produce from 7 to 9 bbbl of recoverable reserves, extendable to 13 bbbl through partial gas reinjection. The first development phase is progressing leveraging on the use of the most advanced techniques in order to cope with high pressures in the reservoir, the presence of high concentration of hydrogen sulphide and harsh environmental conditions. By the end of 2006, works had been completed corresponding to 59% of the initial scope, with the total amount of contracts awarded at $10.6 billion. Drilling activities and completion of development wells from the two artificial islands already installed have been progressing. In addition, three rigs, two of which being of the most advanced class, were installed on said islands. Three development wells were completed yielding high rates of productivity under test phase. Production start-up is currently scheduled for the third quarter of 2010 as compared to an initial forecast

indicating a start-up in 2008, due also to the need on part of Eni to perform certain studies to define measures intended to enhance the overall level of safety and operability of facilities. As a result of said reconfiguration completed by year-end, the onshore design has been confirmed, while certain enhancements have been identified offshore which do not alter the original development concept. These enhancements are expected to be included in the development plan and implemented. Estimated capital expenditure to reach the 300 kbbl/d production target in first development phase stands currently at $19 billion, representing a remarkable increase over the approved budget of $10.3 billion in real terms 2007, sanctioned in 2004. This cost increase was driven by: (i) a cost increase of materials and services driven by sector-specific inflation and a negative impact due to a weakening US dollar; (ii) an underestimation of costs to conduct offshore operations in shallow/ultra shallow waters where the Kashagan field is located due to a lack of benchmarks, also reflecting technical and logistic issues and environmental constraints; (iii) the enhancements to the original layout of offshore facilities. Based on the high level of productivity yielded by the first three development wells, management currently expects a full field production plateau of 1.5 mmbl/d, representing a 25% increase from the original target envisaged by the development plan. Evaluation activities of the discoveries made in the contractual area covered by the North Caspian Sea PSA made some good progress. A first appraisal well of the Kairan discovery was successfully drilled. Drilling of a second appraisal well of the Kalamkas discovery yielded productive results that emphasize the good productivity of the reservoir and a much larger extension of said discovery as compared to the initial estimate. At the Karachaganak field (Eni co-operator with a 32.5% interest), good well performance and high yields of gas treatment and injection plants allowed: (i) to ship an average of 43,900 bbl/d net to Eni to the terminal of the North Caspian Pipeline Consortium at Novorossiysk on the Black Sea; (ii) to sell approximately 78 bcf of natural gas, net to Eni, in Russia. In July 2006, a first cargo of oil was delivered to Odessa and Primorsk via the Atyrau-Samara pipeline, marking the start-up of the Baltic route for the export of production to Western markets. Maintenance activities have been continuing targeting the support of the current liquid production plateau. During the year, new wells were drilled and an upgrading of liquid treatment facilities was sanctioned envisaging the construction of a fourth unit. Such new capacity is expected to increase export of production volumes |  | which were previously marketed on local Russian markets, resulting in an enhancement of prices realizations. Mozambique In March 2006, following an international bid tender, Eni obtained the exploration license for Area 4, located in the deep offshore of the Rovuma Basin. This block covers a gross area of 17,646 square kilometers in an unexplored geological basin with great mineral potential according to surveys performed. In December 2006, Eni signed the relevant exploration contract. Pakistan In February 2006, following an international bid procedure, Eni was awarded the operatorship of four exploration licenses relating to Block Rjar/Mithi - zone I and Thar/Umarkot - zone III. These blocks are located in the East Sindh near the border with India and cover a gross area of about 9,900 square kilometers. In March 2006, an expansion plan of the Bhit and Badhra operated permits was sanctioned, envisaging the construction of a third train for increasing treatment capacity of the Bhit plant also enabling to process Badhra field gas production. In the Zamzama field construction of a new treatment plant is underway. United States - Gulf of Mexico Main discoveries for the year were: a) in Mississippi Canyon Block 546 (Eni’s interest 50%), the Longhorn appraisal well confirmed the presence of natural gas at a depth of about 3,900 meters; b) in Mississippi Canyon Block 502 (Eni’s interest 100%), the Longhorn North discovery well showed the presence of natural gas at a depth of 3,400 meters. A feasibility study to develop this discovery is underway. The Allengheny South (Eni’s interest 100%) and North Black Widow (Eni’s interest 25.19%) fields started production as part of activities to develop reserves in the Gulf of Mexico. United States - Alaska In November 2006, Eni started an exploration campaign in the onshore Rock Flour area (Eni’s interest 100%). The approved plan provides for the drilling of three wells. In March 2006, following an international bid procedure, Eni was awarded 11 exploration blocks near Rock Flour. Eni signed an agreement with a partner for a swap of interests in 64 exploration blocks (Eni’s interest 60%) located in the Beaufort Sea, offshore North Alaska. Based on this agreement, Eni is entitled to 140 exploration blocks (50% of which operated). Exploration plans provide for 3D seismic surveys and drilling of an exploration well by 2010.

United States (Gulf of Mexico): The Allegheny production platform

In January 2006, the development plan of the offshore Oooguruk field in the Beaufort Sea started. Production is expected to start at the end of 2007 with production peaking at 17 kboe/d (over 5 net to Eni) in 2010. Drilling activities in Nikaitchuq field (Eni’s interest 30%), located in the Beaufort Sea, are underway. Turkey In June 2006, construction licenses for the Samsun-Ceyhan pipeline were assigned to the Turkish company Çalik Enerji, partnering Eni in this initiative (both with a 50% stake). This pipeline is expected to bypass the Turkish Straits of Bosphorus and Dardanelles, enabling delivery of oil produced in the Caspian region to the Ceyhan commercial hub on the Mediterranean coast. This new infrastructure will be 550 kilometer long with a maximum transport capacity of 1.5 mmbbl/d of oil, corresponding to approximately 75 mmtonnes/y and will represent a more efficient and environment friendly alternative as compared to the option of transporting oil by ship through the Bosphorus and Dardanelles straits. Construction activities started in second half of 2006. Venezuela In January 2006, following an international bid procedure, Eni was awarded a thirty year long exploration license for the Cardon IV Block (Eni’s interest 50%) in joint venture with an international oil company. This Block is part of the Rafael Urdaneta project for the development of natural gas reserves in an area of about 30,000 square kilometres in the Gulf of Venezuela. In May 2006, a first development phase of the Corocoro field in Gulf of Paria West Block (Eni’s interest 26%) started with some drilling work. A second development phase is expected to be designed based on the results achieved in the first one as regards well production rate and field performance under water and gas injection. |  | Production is expected to start in 2007. With effective date April 1, 2006, the Venezuelan State oil company Petróleos de Venezuela SA (PDVSA) unilaterally terminated the Operating Service Agreement (OSA) governing activities at the Dación oil field where Eni acted as a contractor, holding a 100% working interest. As a consequence, starting on the same day, operations at the Dación oil field are conducted by PDVSA. Eni proposed to PDVSA to agree on terms in order to recover the fair value of its Dación assets. On November 2006, Eni commenced a proceeding before the International Centre for Settlement of Investment Disputes (ICSID) Tribunal (i.e. a tribunal acting under the auspices of the ICSID Convention and being competent pursuant to the Treaty) to claim its rights. In fact, a bilateral investments treaty is in place between the Netherlands and Venezuela (the “Treaty”). Despite this action, Eni is still ready to negotiate a solution with PDVSA to obtain a fair compensation for its assets. Based on the opinion of its legal consultants, Eni believes to be entitled to a compensation for such expropriation in an amount equal to the market value of the OSA before the expropriation took place. The market value of the OSA depends upon its expected profits. In accordance with established international practice, Eni has calculated the OSA’s market value using the discounted cash flow method, based on Eni’s interest in the expected future hydrocarbon production and associated capital expenditures and operating costs, and applying to the projected cash flow a discount rate reflecting Eni’s cost of capital as well as the specific risk of concerned activities. Independent evaluations carried out by a primary petroleum consulting firm fully support Eni’s internal evaluation. The estimated net present value

ENI ANNUAL REPORT / OPERATING REVIEW

of Eni’s interest in the Dación field, as calculated by Eni, is higher than the net book value of the Dación assets which consequently have not been impaired. In accordance with the ICSID Convention, a judgement by the ICSID Tribunal awarding compensation to Eni would be binding upon the parties and immediately enforceable as if it were a final judgement of a court of each of the States that have ratified the ICSID Convention. The ICSID Convention was ratified in 143 States. Accordingly, if Venezuela fails to comply with the award and to pay the compensation, Eni could take steps to enforce the award against commercial assets of the Venezuelan Government almost anywhere those may be located (subject to national law provisions on sovereign immunity). In 2005 and in the first quarter of 2006, oil production from the Dación field averaged approximately 60 kbbl/d and booked reserves at December 31, 2005 amounted to 175 mmbbl. On February 26, 2007, the President of Venezuela enacted a decree providing for the transformation of certain strategic partnerships operating in the petroleum region of Orinoco (Faja) and certain agreements to conduct risk shared exploration activities into a regime of “empresa mixta” within six months from publication of said decree. Under the new regime, a company incorporated under the law of Venezuela is expected to be entitled to relevant mineral rights and to conduct petroleum operations. A stake of at least 60% in the capital of such company is expected to be held by an affiliate of PDVSA, preferably Corporación Venezuelana de Petróleo. Such decree could impact Eni’s activities in Venezuela, as Eni’ s subsidiary Eni Venezuela |  | BV holds a stake in a joint venture operating the Gulf of Paria West Block, located in the Orinoco delta as outlined above. However, management is currently unable to assess such impact, as terms and conditions regulating the participation of foreign companies to an “empresa mixta” have not yet been agreed upon. Italy Main gas discoveries for the year were made in: a) the onshore San Polito concession in Emilia, the Longanesi 1 well, at a depth of 2,540 meters; b) the offshore of Sicily (GR.13.AG permit, Argo 1 well, Eni’s interest 60%) at a depth between 1,350 and 1,520 meters; c) the Adriatic Sea (AR.95.EA permit, Benedetta 1 well) at a depth of 2,090 meters which yielded 145 kcm/d of gas in test production; d) the onshore of Sicily (San Teodoro permit, Borgo Giuliano 1 well) at a depth of about 2,000 meters. Development activities concerned in particular: (i) optimization of producing fields by means of sidetracking and infilling (Barbara A/H, Daria, Basil and Anemone for gas and Rospo for oil); (ii) continuation of drilling and upgrading of producing facilities in the Val d’Agri. The main oil reserves development project is Miglianico, located onshore in the Abruzzi Region. Production is expected to start in the second half of 2008. This project provides for the construction of facilities intended to treat production volumes of oil, to be delivered to logistic structures of the Refining & Marketing Division, and to desulfurize production volumes of gas to be input into the Italian natural gas transportation network.

ENI ANNUAL REPORT / OPERATING REVIEW

Development of onshore gas fields is nearing completion at: (i) Tea, Arnica, Lavanda in the Adriatic offshore where start-up of production is expected in 2007. In 2006, a production platform and linkage facilities have been installed; (ii) Candela, where start-up is expected in 2007; (iii) certain gas fields in Sicily: Pizzo Tamburino, scheduled for the second half of 2007 with expected production of 0.5 kboe/d, Samperi 1, which started in 2006 with a production peak of approximately 1 kboe/d, and recovery of additional reserves of Fiumetto concession, where start-up is expected in the first half of 2007 peaking at 600 boe/d. Capital expenditure In 2006, capital expenditure of the Exploration & Production segment amounted to euro 5,203 million and concerned mainly development expenditure, directed mainly outside Italy, in particular in Kazakhstan, Angola and Egypt. Development expenditure in Italy concerned in particular the continuation of drilling development wells, the completion of work for plant and infrastructure in Val d’Agri and sidetrack and infilling actions in mature areas. Exploration expenditure, of which 90% was directed outside Italy, concerned in particular Angola, Egypt, Norway, Nigeria and the Gulf of Mexico. In Italy exploration concerned essentially the offshore of Sicily, the Po Valley and the Adriatic Sea. |  | As compared to 2005, capital expenditure increased by euro 238 million, up 4.8%, due to the increase in exploration expenditure mainly in Egypt and Nigeria. These effects were offset in part by lower development expenditure resulting essentially from the completion of relevant projects in Libya (Bahr Essalam), Nigeria (trains 4 and 5 of the Bonny LNG plant) and the purchase of an additional 1.85% interest in the Kashagan field in the first half of 2005 (euro 169 million). Storage Natural gas storage activities are performed by Stoccaggi Gas Italia SpA (“Stogit”) to which such activity was conferred on October 31, 2001 by Eni SpA and Snam SpA, in compliance with Article 21 of Legislative Decree No. 164 of May 23, 2000, which provided for the separation of storage from other activities in the field of natural gas. Storage services are provided by Stogit through eight storage fields located in Italy, based on 10 storage concessions vested by the Ministry of Productive Activities. In 2006, the share of storage capacity used by third parties was 46%. From the beginning of its operations, Stogit markedly increased the number of customers served and the share of revenues from third parties; the latter, from a non significant value, passed to 42%.

Regulatory framework Storage code With Resolution No. 220/06, the Italian Authority for Electricity and Gas approved the storage code proposed by Stoccaggi Gas Italia on the basis of the framework and criteria established by Resolution No.119/05 (“Adoption of guarantees for free access to natural gas storage services, duties of subjects operating storage activities and rules for the preparation of a storage code”). This code disciplines access to and provision of storage services during normal operational conditions, regulates procedures for conferring storage capacities, |  | fulfilment of obligations concerning operating programming and fees to be charged to customers. The code has been in force since November 1, 2006, as of the beginning of the storage cycle. The storage company offers services, on economic conditions and according to an access priority established by the Italian Authority for Electricity and Gas as follows: (i) services which the storage company is obliged to offer consisting of: modulation storage services, mineral storage services, and strategic storage services. (ii) operating balancing services of transport companies, including hourly modulation.

ENI ANNUAL REPORT / OPERATING REVIEW

The modulation storage service is finalized to satisfy daily, seasonal and eloinare demand peak modulation needs. Final clients consuming less than 200,000 cm on an annual basis are entitled to a priority when satisfying their modulation requirements. To that end, the storage company makes available its capacity for space, injection and offtake on an annual basis in accordance with its storage code. The mineral storage service is finalized to allow natural gas producers to perform their activity under optimal operating conditions, according to criteria determined by the Ministry of Economic Development. The strategic storage service is destined to satisfy certain obligations of natural gas importers from countries not belonging to the EU in accordance with Art. 3 of Legistlative Decree No. 164/2000. The relevant storage capacity dedicated to this service is determined by the Ministry of Economic Development. Determination of tariffs According to Resolution No. 50/06 of the Italian Authority for Electricity and Gas (“Criteria for the determination of tariffs for natural gas storage services”), the storage company calculates revenues for the determination of unit tariffs for storage services by adding the following cost elements: i) a return on the capital employed by the storage company equal to 7.1% (8.33% in the first regulated period). The Resolution confirmed the mechanisms for the evaluation of net capital employed established in the prior regulatory period; ii) technical and economic depreciation charges; iii) operating costs. |  | In the years following the first year of the new regulated period, reference revenues are updated to take account of variations of capital employed and the impact of the indexation of depreciation charges and operating costs to consumer price inflation lowered by a preset rate of productivity recovery. Storage tariffs are articulated as follows: i) a unit fee for the use of space; ii) a unit fee for the use of injection capacity; iii) a unit fee for the use of offtake capacity; iv) a unit fee for gas volumes handling; v) a unit fee for having such volumes of gas available as necessary to fulfil strategic storage obligations on part of interested operators. Applicable regulation provides for incentives to capital expenditure intended to develop and upgrade storage capacity by recognizing an additional rate of return of 4% on the basic rate to capital expenditure projects aiming at developing new storage deposits and increasing existing capacity. Such incentives are applicable for a sixteen-year period and an eight-year period, respectively. Fees charged for balancing activities and storage restoration Fees deriving from balancing activities and restoration of strategic volumes offtaken are regulated by certain prescriptions from the Italian Authority for Electricity and Gas providing for repartition of such fees among customers of storage services until the 2005-2006 thermal year. Resolution No. 50/2006 changed such regime by establishing that such fees cover revenues deriving from new investment.

Strategic agreement with Gazprom
› In November 2006, Eni and Gazprom signed a broad strategic agreement. This agreement strengthens a long term partnership between the two companies and represents a fundamental step towards the security of energy supplies to Italy. Key features of this deal are the extension of the duration of Gazprom gas supply contracts to Eni until 2035, further strengthening Eni’s supply portfolio and the pursuing of joint initiatives in the upstream sector. Gazprom is expected to enter the Italian market by selling volumes of gas starting in 2007. Gazprom will obtain the availability of such volumes by means of a corresponding reduction in volumes previously supplied to Eni

ENI ANNUAL REPORT / OPERATING REVIEW

Financial results
› The Gas & Power business confirmed its ability to generate strong and stable performances. The adjusted net profit rose euro 310 million to euro 2,862 million compared to 2005 (up 12.1%) reflecting primarily higher selling margins on natural gas sales, a lower impact of Resolution No. 248/2004 of the Italian Authority for Electricity and Gas, a growth in natural gas volumes sold, volumes transported for the coming on line of the GreenStream gasline and electricity production sold

› Return on average capital employed was 15.1% on an adjusted basis in 2006 (13.7% in 2005)

› Capital expenditure totalled euro 1,174 million and related essentially to development and maintenance of Eni’s transport and distribution networks in Italy, the finalization of the upgrading plan of electricity generation capacity and the start up of the upgrading plan of import gaslines

Operating results
› Natural gas sales were up approximately 4% to 97.48 bcm primarily reflecting a growth in sales in a number of target European markets (up approximately 16% in particular in Turkey, Germany/Austria, France) also for the build-up of supplies of natural gas from Libya, partly offset by a decrease in sales in Italy due to mild weather conditions in the fourth quarter of the year

› Electricity production sold was 24.82 terawatthour, up 9% compared with 2005 reflecting the ramp-up of new production capacity

Other developments
› As a part of its development strategy of the natural gas distribution and sale businesses by means of regional alliances, Eni and its local authority partners defined the Toscana project with the establishment of a regional distribution company, managed by Eni and boasting 1.6 million users and a regional selling company controlled by Eni boasting 600 thousand clients and 1.1 billion cubic meters of annual sales

NATURAL GAS Supply of natural gas In 2006, Eni’s Gas & Power segment supplied 89.27 bcm of natural gas, with an increase of 6.71 bcm from 2005, up 8.1%. Natural gas volumes supplied outside Italy (79.06 bcm) represented 89% of total supplies of fully consolidated subsidiaries (87% in 2005) with a 7.23 bcm increase from 2005 (up 10.1%), primarily reflecting the reaching of full volumes of supplies from Libyan fields (up 2.79 bcm), higher purchases from the Netherlands (up 1.99 bcm), from Russia to the Turkish market (up 1.21 bcm) and via LNG (1.01 bcm). In addition, supplies from Croatia increased (up 0.43 bcm) due to the ramp-up of new production from Eni-operated natural gas fields in the Adriatic offshore. The main declines concerned purchases from Algeria (down 0.74 bcm) and extra Europe supplies. Supplies in Italy (10.21 bcm) declined by 0.52 bcm, down 4.8%, from 2005, due to a production decline of Eni’s natural gas fields. |  |

ENI ANNUAL REPORT / OPERATING REVIEW

In 2006, natural gas volumes input to storage deposits owned by Stoccaggi Gas in Italy and Gaz de France in French territory and in Austria were 3.01 bcm, compared to net offtakes of 0.84 bcm in 2005. TAKE-OR-PAY In order to meet the medium and long-term demand for natural gas, in particular in the Italian market, Eni entered into long-term purchase contracts with producing countries. Specifically, following the strategic agreement with Gazprom signed on November 14, 2006, effective from February 1, 2007, Eni extended the duration of its gas supply contracts with Gazprom until 2035, bringing the residual average life of its supply portfolio to approximately 23 years. Existing contracts, which in general contain take-or-pay clauses, will ensure a total of approximately 62.4 bcm/y of natural gas by 2010. Despite the fact that an increasing portion of natural gas volumes purchased under said contracts has been sold outside Italy, management believes that in the long term unfavorable trends in the Italian demand and supply for natural gas, also due to the possible implementation of all publicly announced plans for the construction of new supply infrastructure, and |  | the evolution of Italian regulations of the natural gas sector, represent risk factors to the fulfilment of Eni’s obligations in connection with its take-or-pay supply contracts. Sales of natural gas Natural gas sales (97.48 bcm, including own consumption, Eni’s share of affiliates sales and upstream sales in Europe) were up 3.27 bcm from 2005, or about 4%, due to higher sales in the rest of Europe (4.9 bcm, up approximately 16%), higher supplies of natural gas to Eni’s wholly-owned subsidiary EniPower for power generation (up 0.59 bcm, or 10.6%), offset in part by lower sales by fully consolidated subsidiaries in Italy (down 1.53 bcm, or 2.9%). In an increasingly competitive market, natural gas sales of fully consolidated subsidiaries in Italy (50.94 bcm) declined by 1.53 bcm from 2005, due to lower supplies related to mild weather conditions in the fourth quarter, negatively affecting sales volumes to the power generation segment (down 0.93 bcm), wholesalers (down 0.51 bcm) and residential and commercial users (down 0.4 bcm) , offset in part by higher sales to the industrial sector (up 0.26 bcm). Sales under the so-called gas release1 (2 bcm) increased by 0.05 bcm from 2005.

(1) |  | In June 2004 Eni agreed with the Antitrust Authority to sell a total volume of 9.2 bcm of natural gas (2.3 bcm) in the four thermal years from October 1, 2004 to September 30, 2008 at the Tarvisio entry point into the Italian network.

ENI ANNUAL REPORT / OPERATING REVIEW

Own consumption2 was 6.13 bcm, up 0.59 bcm or 10.6%, reflecting primarily higher supplies to EniPower due to the coming on stream of new generation capacity. In 2006, natural gas sales of fully consolidated subsidiaries in the rest of Europe increased by 4.49 bcm to 27.93, or 19.2%, reflecting a growth in: (i) sales under long-term supply contracts to Italian importers (up 2.57 bcm) for the progressive reaching of full supplies from Libyan fields; (ii) supplies to the Turkish market (up 1.22 bcm); (iii) Germany and Austria (up 0.84 bcm) essentially due to increased spot sales to Gaz de France and higher supplies to other industrial operators and wholesalers; (iv) France (up 0.42 bcm) relating to higher supplies to industrial operators. These increases were partly offset by a decrease in sales in Hungary (down 0.29 bcm) and Northern Europe (down 0.1 bcm). Sales of natural gas by Eni’s affiliates in the rest of Europe, net to Eni and net of Eni’s supplies, amounted to 6.88 bcm, up 0.4 bcm with Unión Fenosa Gas posting the major increase, and concerned: (i) GVS (Eni’s interest 50%) with 2.94 bcm; (ii) Unión Fenosa Gas |  |
(Eni’s interest 50%) with 2.17 bcm; and (iii) Galp Energia (Eni’s interest 33.34%) with 1.65 bcm.

ENI ANNUAL REPORT / OPERATING REVIEW

Unión Fenosa Gas sold 0.45 bcm in international markets, in particular in Japan (0.27 bcm) and South Korea (0.09 bcm), as new market opportunities arose allowing to optimize selling margins. Transport and regasification of natural gas In 2006, volumes of natural gas input in the national grid (87.99 bcm) increased by 2.89 bcm from 2005, up 3.4%, primarily reflecting higher volumes input to storage. Eni transported 30.9 bcm of natural gas on behalf of third parties in Italy, up 0.68 bcm from 2005, or 2.3%. In 2006, the LNG terminal in Panigaglia (La Spezia) regasified 3.13 bcm of natural gas (2.49 bcm in 2005), discharging 96 tanker ships (79 in 2005). The increase |  | in volumes regasified reflected a higher availability of LNG on the market. Development projects LNG Egypt Eni, through its interest in Unión Fenosa Gas, owns a 40% stake in the Damietta liquefaction plant producing approximately 5 mmtonnes/y of LNG equal to a feedstock of 7.6 bcm/y of natural gas. In June 2006, the partners of the project (Unión Fenosa Gas, the Spanish-Egyptian company SEGAS an affiliate of Unión Fenosa Gas, State owned Egyptian companies EGAS and EGPC, and oil producers Eni and BP) defined terms and conditions for doubling the plant capacity by means of another treatment train.

approximately $1.5 billion; start-up is expected by 2010. For further information about the upstream section of the project see “Exploration & Production - Main exploration and development projects”. The project also foresees the construction of two tankers each with a capacity of 155,000 cm. LNG Spain In April 2006, the Sagunto regasification plant with a capacity of 6.7 bcm/y started operations near Valencia. Eni, through Unión Fenosa Gas, holds a 21.25% interest in this plant. At present, Eni’s share of regasification capacity amounts to 1.6 bcm/y of gas. A capacity upgrading plan has been sanctioned targeting a 0.8 bcm/y capacity increase by 2009. Relevant works started in the second half of 2006. Eni through Unión Fenosa Gas also holds a 9.5% interest in the El Ferrol regasification plant, located in Galicia, under construction and expected to be completed by the first half of 2007, targeting a treatment capacity of approximately 3.6 bcm/y, 0.4 bcm/y being Eni’s share. Marketing actions in Germany and France In 2006, Eni began to supply the German company Wingas under a long-term contract, envisaging 1.2 |  | bcm/y of natural gas. The gas is delivered at Eynatten at the German-Belgian border. Marketing activities targeting an increase in natural gas sales in Germany and the pursuit of new opportunities arising from the ongoing liberalization process have been started. In 2006, Eni started direct sales of natural gas in the French market with a new branch in Paris. New industrial and wholesaler clients were acquired; sales for the year hit the 1 bcm level. Supplies to the French company EDF ramped up, in execution of the long term supply contract signed in July 2005. Galp On March 29, 2006, an eight-year agreement among Galp partners became effective addressing the joint management of the company. Galp partners include Eni, Amorim Energia (a privately held Portuguese company in which Sonangol, the national oil company of Angola, holds a minority stake), Rede Electrica Nacional (REN), and Caixa Geral de Depositos (a primary Portuguese financial institution). On September 26, 2006, in accordance with the

agreement, Galp’s regulated activities comprising a high pressure network, storage sites and a regasification terminal located in Sines were spinned-off and sold to REN which exited Galp capital on October 18, 2006. On October 24, 2006, the Portuguese State divested part of its stake in Galp through an IPO. At the same time, Galp shares were registered on the national Portuguese stock exchange. The shareholders of Galp post-IPO are: Eni (33.34%), Amorim Energia (33.34%), the Portuguese State (7.00%), Iberdrola (4%), Caixa (1%) and Setgas (0.04%); floating shares represent 21.28 % of the share capital. Upgrade of import gaslines Eni started implementing the upgrading plan of the natural gas import gaslines TTPC from Algeria and TAG from Russia. TTPC - Algeria The transport capacity of the TTPC gasline from Algeria is expected to be increased by 6.5 bcm/y of which a 3.2 bcm/y portion is planned to come on line on April 1, 2008, and a 3.3 bcm/y portion on October 1, 2008. Capital expenditure is expected at euro 450 million, increasing the amount initially budgeted in 2005 due to cost overruns and revisions of the engineering of the project. When the upgrading is fully operational, the gasline will deploy a transport capacity of 33.5 bcm/y. A corresponding capacity on the TMPC downstream gasline is already available. TMPC crosses underwater the Sicily channel. The first portion of the TTPC upgrade was assigned to third parties in November 2005. |  | The procedure to assign the second portion was closed in February 2007. TAG - Russia The transport capacity of the TAG gasline from Russia is expected to increase by 6.5 bcm/y coming on line on October 1, 2008. Expected capital expenditure amounts to euro 253 million; Eni’s share of this expenditure is 94%. A 3.2 bcm portion of the upgrade was assigned to third parties in February 2006 and the procedure assigning the residual portion has been defined. At the beginning of 2007, a previously implemented upgrade of this gasline came on line in order to allow the build up of the fourth supply contract from Russia. As a result, the gasline transport capacity increased from 33 to 37 bcm/y. The ongoing upgrading plan is expected to increase the gasline transport capacity to 44 bcm/y by 2009. GreenStream - Libya Eni plans to upgrade the GreenStream import gasline from Libya in order to expand volumes input in the national transport network by 3 bcm/y. Said upgrade is expected to come on line by 2011 and to entail an expenditure of euro 84 million. When the ongoing plan of upgrading the TTPC and TAG gasline is fully operational and taking into account the full capacity of the GreenStream gasline from Libya currently in place (8 bcm/y), a total of approximately 21 bcm/y of new import capacity will be available to third parties on the basis of non-discriminating procedures of allocation (17.7 bcm of this new capacity have already been allocated to third parties).

Italy (Panigaglia): Regasification terminal Regasification terminal Eni plans to build a new regasification terminal located off the Adriatic coast and to increase the capacity of the Panigaglia plant. These two projects are expected to upgrade the import capacity to Italy by 8 and 4.5 bcm/y, respectively, when fully operational. The planned start-up is expected by 2013 and 2014, respectively. The capital expenditure expected for the offshore regasification project amounts to approximately euro 800 million. In 2006, preliminary studies were performed in order to screen potential sites where the terminal may be located and on the configuration of the plant. Agreement between Eni and Gazprom On November 14, 2006, Eni and Gazprom signed a broad strategic agreement. This agreement sets up an international alliance enabling the two companies to launch joint projects in the mid and downstream gas, in the upstream and technological cooperation. This agreement is a major step towards the security of energy supply to Italy. i) Midstream and downstream gas The duration of Russian gas supply contracts to Eni is extended until 2035, confirming that Eni is presently the world’s single largest customer of Gazprom. Through this agreement, starting from 2007, Gazprom is expected to sell increasing volumes of gas directly on the Italian market, building up to some 3 bcm in 2010 and to maintain such level in subsequent years for the duration of said long term supply contract. Volumes expected to be sold by Gazprom will be subtracted from volumes supplied to Eni under the fourth |  | long-term supply contract. In 2007, Eni expects to reduce its supplies from Gazprom by 1 bcm, and Gazprom to sell approximately 1 bcm under this scheme. ii) Upstream Eni and Gazprom have identified major projects (companies and assets) in Russia and outside Russia that will be jointly pursued by the two partners. Eni and Gazprom have agreed to work with each other on an exclusive basis on these projects, which are expected to be finalized by the end of 2007. iii) Technological cooperation and development Eni and Gazprom will sign specific agreements in the following areas: long-distance gas transportation. In this sector Eni and Snam Rete Gas will provide their know-how and expertise, including proprietary transport technology TAP (high pressure transmission) for the development of Russia’s gas transportation system; development of LNG projects for the global gas market. Agreement between Eni and Nigeria LNG Eni signed a twenty-year sale and purchase agreement with Nigeria LNG (NLNG) Limited for the purchase of 1.375 mmtonnes/y (equivalent to approximately 2 bcm/y) of (LNG). LNG volumes sold to Eni are part of the volumes which are expected to be produced from the expansion of the capacity of the Bonny plant by means of the installation of a seventh train expected to come into operation in 2012. LNG will be delivered by Nigeria LNG to the terminal of Cameron, Louisiana, where Eni already holds regasification capacity for about 6 bcm/year and will be sold to the US market. The volumes of LNG delivered to Eni through this agreement represent about 17% of the whole production of Bonny’s Train 7 expansion. This agreement will make a further sizeable contribution to Eni's supply portfolio, enabling the company to strengthen its activities in the US and its role as leading player in the global LNG market. Toscana project On January 24, 2006, Eni, Italgas (Eni’s interest 100%) and the local authorities partners of Fiorentina Gas SpA (Eni’s interest 51.03%) and Toscana Gas SpA (Eni’s interest 46.1%), signed a framework agreement for developing an alliance in the field of natural gas distribution and sale in the Toscana Region.

ENI ANNUAL REPORT / OPERATING REVIEW

As a part of the agreement, Toscana Energia SpA (Eni’s interest 48.72%) was established upon contribution in-kind of the partners’ stakes in the distribution companies Fiorentina Gas and Toscana Gas. The local authorities partners of Toscana Energia SpA hold the responsibility for strategic decisions and control, while Eni maintains operating and management responsibilities, being the industrial partner of the initiative. In addition, this agreement provides for Fiorentina Gas Clienti SpA (Eni’s interest 100%) to be merged into Toscana Gas Clienti SpA (Eni’s interest 46.1%, Tuscan municipalities 53.9%), resulting in the establishment of a regional selling company under Eni’s control (79.22%), re-named Toscana Energia Clienti and boasting 600 thousand clients and sale volumes of 1.1 bcm/y in 147 Tuscan municipalities. The Italian Antitrust Authority authorized this transaction on July 20, 2006. The merger deed was defined on February 22, 2007, effective from March 1, 2007. Restructuring power activities and launching of Dual Offer In 2006, the G&P division started a project aiming at revamping the power generation business. Under this project, the G&P division is expected to conduct directly the marketing activity of electricity, previously conducted by EniPower, starting in 2007. This scheme will allow the integrated management of marketing activities of gas and electricity and the development of a joint-offer of natural gas and electricity to customers. Regulatory framework Determination of reference prices for non eligible customers at December 31, 2002 - Resolutions No. 248/2004 and 134/2006 of the Italian Authority for Electricity and Gas With a decision of November 13, 2006, the Council of State concluded the dispute between operators of the natural gas business, among which Eni, and the Italian Authority for Electricity and Gas related to Resolution No. 248 of December 29, 2004 “Determination of reference prices for non eligible customers at December 31, 2002” confirming the existence of formal flaws impairing the efficacy of the appeal presented by the Authority against the first degree decision that annulled the Authority’s decision against operators. As far as the substance of the appeal is concerned, the Council of State previously stated that the Authority is entitled to hold such powers as to regulate certain activities of the energy sector in Italy which |  | were liberalized by Law No. 239/2004 (in particular the sale of natural gas). Said regulatory powers enable the Authority to preserve competition and protect final clients. Based on these considerations and on the uncertainty of the efficacy of decisions implementing Resolution No. 248/2004 (among these No. 298/2005, No. 65/2006 and No. 134/2006) Eni’s management prepared its consolidated financial statements for 2006 by assessing the impact of the regulatory regime based on the indexation mechanism set out by Resolution No. 248/2004. This treatment was consistent with the one adopted in the preparation of quarterly and semi-annual accounts for 2006. In addition, Eni began to renegotiate the terms of supply contracts with its wholesale customers as provided for by Resolution No. 134/2006, which obliged Italian wholesalers to offer final clients new pricing terms which take into account the revision of the indexation mechanism of the raw material component as introduced by Resolution No. 248/2004. This provision applies only to wholesale contracts closed after the entry into force of Resolution No. 248/2004. The provision accrued in the 2005 consolidated financial statements as an estimate of the impact of the indexation mechanism of Resolution No. 248/2004 in 2005 was deemed partially redundant as a result of the provisions of Resolution No. 134/2006. In fact, Resolution No. 134/2006 granted to companies complying with the renegotiation requirement an amount corresponding to 50% of the difference between the updating of the cost of raw materials calculated under Resolution No. 284/2005 and that calculated under the previous regime (under Resolution No. 195/2002) for the 2005 fiscal year as well as 50% of the variable compensation component in wholesale contracts. For further information on this matter see Eni’s Report on the First Half of 2006 - Operating Review - Gas & Power - Regulation - Determination of reference prices for non eligible customers at December 31, 2002 - Resolutions No. 248/2004 and No. 134/2006 of the Italian Authority for Electricity and Gas. With Resolution No. 12/2007 of January 23, 2007, the Italian Authority for Electricity and Gas started a procedure to adopt a new indexation mechanism of the cost of raw material effective retroactively as of January 1, 2005. On March 1, 2007, the Authority published a consultative document. Opening of an inquiry on prices from the Italian Authority for Electricity and Gas With Resolution No. 226/2006 of October 21, 2006,

ENI ANNUAL REPORT / OPERATING REVIEW

Italy: Control room of the Ferrera Erbognone EniPower station.

the Italian Authority for Electricity and Gas closed a formal inquiry against Eni that commenced with Resolution No. 107/2005, stating that Eni allegedly failed to comply with an obligation to transmit certain pieces of information regarding Eni’s natural gas import contracts to the Authority. Therefore, the Authority fined Eni by an amount of euro 10 million. In spite of the circumstance that Eni spontaneously transmitted the requested pieces of information, the Authority objected to the fact that Eni delayed the fulfilment of its obligation to transmit said information, resulting in a behaviour in breach of the rules requiring the establishment of information flows intended to allow the Authority to perform its tasks. Eni filed a claim against the Authority’s decision before the Regional Administrative Court of Lombardy. For further information on this matter see Eni’s Report on the First Half of 2006 - Operating Review - Gas & Power - Regulation - Opening of an inquiry on prices from the Authority for Electricity and Gas. Eni accrued a provision for this matter. Inquiry of the Italian Authority for Electricity and Gas on behaviors of operators selling natural gas to end customers With Resolution No. 235/06 of November 6, 2006, the Italian Authority for Electricity and Gas closed the inquiry that started in October 2005, on the commercial behavior of companies selling natural gas to end customers located in urban centers (residential, services, commercial activities and small enterprises) aiming at acquiring new customers or re-acquiring customers transferred to other sellers, with particular reference to hurdles posed by companies to customers wishing to leave one distributor or to the entry of competitors on the market. In its final report, |  | the Authority confirmed the existence of certain critical points about the real level of competition within this market segment and proposed different options to complete and adjust the regulatory framework in order to overcome acknowledged deficiencies. Resolution No. 137/2002 of the Italian Authority for Electricity and Gas - Access to transport services and Network Code of Snam Rete Gas The Italian Authority for Electricity and Gas, with Resolution No. 137/2002, defined the criteria for regulating access to national natural gas transport networks, in particular the issue of priority. Eni filed a claim against this decision with the Regional Administrative Court of Lombardy that was partially accepted with the Court’s resolution on December 2004. The Authority filed a claim against this decision with the Council of State and informed Eni on February 19, 2004. The hearing for the discussion of this case has not yet been scheduled. Legislative Decree No. 164/2000 Legislative Decree No. 164/2000 imposed thresholds to operators until December 31, 2010 in relation to a percentage share of domestic consumption set as follows: (i) 75%, from January 1, 2002, for imported or domestically produced natural gas volumes input in the domestic transmission network destined to sales; this percentage decreases by 2 percentage points per year until it reaches 61% in 2009; (ii) 50% from January 1, 2003 for sales to final customers. These ceilings are calculated net of volumes consumed in operations and

39

in the case of sales also net of losses. The decree also provides for periodic controls of the respect of said ceilings. This control is performed each year by the Italian Antitrust Authority by comparing the allowed three-year average percent share of domestic consumption for both input volumes and sales volumes with the one actually achieved by each operator. In particular, 2006 closes the third three-year regulated period for natural gas volumes input in the domestic transmission network, for which the allowed percentage was 69% of domestic consumption of natural gas, and the second three-year regulated period for sales volumes. Eni’s presence on the Italian market complied with said limits. POWER GENERATION Eni’s electricity business is conducted by EniPower SpA and its subsidiaries owning power stations located at Eni’s sites in Ferrera Erbognone, Ravenna, Livorno, Taranto, Mantova, Brindisi and Ferrara with an installed capacity of 4.9 gigawatts as of December 31, 2006. Eni is implementing an upgrading plan of its power generation capacity, targeting an installed capacity of 5.5 gigawatt in 2010. When this capacity is on line in 2010, production volumes are expected at 31 terawatthour, corresponding to approximately 8% of expected volumes of electricity generated in Italy by that year. Planned capital expenditure amounts to approximately euro 2.4 billion, of these euro 2 billion have already been deployed. The development plan has been completed at all sites except for Ferrara (Eni’s interest 51%), where in partnership with Swiss company EGL AG, construction of two new 390 megawatt combined cycle units is |  | underway. This will bring installed capacity to 840 megawatt and with start-up is expected in the second half of 2007. Moreover, Eni has planned the installation of a new 240 megawatt combined cycle unit located in Taranto (current capacity 75 megawatt). New installed generation capacity uses the combined cycle gas fired technology (CCGT), ensuring a high level of efficiency and low environmental impact. In particular, management estimates that for a given amount of energy (electricity and heat) produced, the use of the CCGT technology on a production of 30 terawatthour reduces emissions of carbon dioxide by approximately 11 million tonnes, as compared to emissions using conventional power generation technology. In 2006, electricity production sold was 24.82 terawatthour, up 2.05 terawatthour or 9% as compared to 2005. Increased production reflected the ramp-up of the three combined cycle units at the Brindisi plant entering full commercial operation since September 2006 (up approximately 3 terawatthour) and of the two combined cycle units at the Mantova plant fully operational in 2006 (up 0.9 terawatthour). These increases were offset in part by the standstill of the Ravenna power plant (down 0.85 terawatthour) due to maintenance activity. Eni also purchased 6.21 terawatthour from third parties in and outside Italy. Sales of steam amounted to 10,287 million tonnes, down 3.5% from 2005. Approximately 55% of sales were directed to end users, 28% to the Electricity Exchange, 8% to GRTN/Terna (under CIP 6/92 contracts and imbalances in input) and 9% to wholesalers. All the steam produced was sold to end users.

Financial results
› In 2006, adjusted net profit was down euro 316 million to euro 629 million, or 33.4%, mainly due to a decline in refining margins as a result of a weak trading environment

› Eni’s realized refining margins recorded a better trend than market reference margins reflecting Eni’s refinery capacity to process heavy crudes which are discounted as compared to the Brent crude market benchmark, thus resulting in a higher profitability of the heavy barrel

ENI ANNUAL REPORT / OPERATING REVIEW

› Return on average capital employed was 10.7% on an adjusted basis, declining from 2005 (18.2% in 2005)

› Capital expenditure totalled euro 645 million and mainly related to projects aimed at improving flexibility and yields of refineries and upgrading the refined product retail network in Italy and in the rest of Europe

Operating results
› Refining throughputs on own account in Italy and outside Italy (38.04 mmtonnes) declined by 0.75 mmtonnes from 2005, down 1.9%, due mainly to higher maintenance standstills, particularly at third party refineries, while wholly-owned refineries achieved stable processing levels

› Retail sales of refined products in Italy (8.66 mmtonnes) declined 1% from 2005 mainly due to competitive pressure. This decrease was more than offset by a growth in retail volumes marketed in the rest of Europe (3.82 mmtonnes, up 4.1%), mainly in Germany and Spain

› Sales on the wholesale market in Italy (10.06 mmtonnes) were down 4% due primarily to the decline registered in the fourth quarter due to the impact of mild weather conditions. This decline was partially offset by a growth in volumes marketed on wholesale markets in the rest of Europe (4.6 mmtonnes, up 2.2%), in particular in Germany and Spain

Supply and trading In 2006, a total of 65.70 mmtonnes of oil were purchased (66.48 mm in 2005), of which 36.81 mmtonnes from Eni’s Exploration & Production1 segment, 18.16 mmtonnes under long-term contracts with producing countries and 10.73 mmtonnes on the spot market. Some 21% of oil purchased came from West Africa, 21% from North Africa, 18% from countries of the former Soviet Union, 14% from the Middle East, |  | 14% from the North Sea, 7% from Italy and 5% from other areas. Some 30.66 mmtonnes were traded, down 1.3% from 2005. In addition, 3.18 mmtonnes of intermediate products were purchased (3.58 in 2005) to be used as feedstock in conversion plants and 16 mmtonnes of refined products (16.21 in 2005) were purchased to be sold on markets outside Italy (11.48 mmtonnes) and on the Italian market (4.52 mmtonnes) as a complement to own production.

(1) |  | The Refining & Marketing segment purchased approximately two-thirds of the Exploration & Production segment’s oil and condensate production and resold on the market those crudes and condensates that are not suited for processing in its own refineries due to their characteristics or geographic area.

ENI ANNUAL REPORT / OPERATING REVIEW

Refining In 2006, refining throughputs on own account in Italy and outside Italy were 38.04 mmtonnes, down 0.75 mmtonnes from 2005, or 1.9%, owing to lower throughputs on third party refineries as a consequence of an accident occurred at the Priolo refinery and a maintenance standstill at the Milazzo refinery (Eni’s interest 50%). Refining throughputs on own account were stable. In particular, refining throughputs increased at the Venice, Gela and Taranto refineries and decreased at the Sannazzaro refinery due to a maintenance standstill of the catalytic cracking unit and the visbreaking unit, and at the Livorno refinery due to general maintenance activity. In April, a new unit for heavy residue gasification started operating at the Sannazzaro refinery. Total throughputs on wholly-owned refineries (27.17 mmtonnes) decreased 0.17 mmtonnes from 2005, down 0.6%; balanced capacity of refineries was fully utilized. Approximately 35.9% of volumes of processed oil was supplied by Eni’s Exploration & Production segment (32.3% in 2005), representing a three percentage point increase from 2005. Incremental volumes of some 1.1 mmtonnes of equity oil processed related to higher supplies of heavy oil from Nigeria (due to the start-up of the Bonga field) and from Sicily, against a reduction of supplies of the Libyan Bu-Attifel oil processed at Priolo. Distribution of refined products In 2006, sales volumes of refined products (51.13 mmtonnes) were down 500 ktonnes from 2005, or 1%, mainly due to lower wholesale volumes (down |  |
320 ktonnes) as a consequence of mild weather conditions in the last part of the year adversely affecting heating products sales. In addition, lower volumes were supplied to the petrochemical sector (down 460 ktonnes) owing to the technical accident that occurred at the Priolo refinery. These declines were offset in part by higher sales to oil companies and traders and by a growth in retail sales on the Agip branded network in Italy and outside Italy (up 60 ktonnes). The impact of the Italiana Petroli (IP) divestment, effective September 1, 2005 (1.3 mmtonnes), was partly offset by supply of fuels to the same company under a five-year contract signed concurrently with the divestment.

Retail sales in Italy Retail volumes of refined products marketed on the Italian network (8.66 mmtonnes) were down 1.39 mmtonnes from 2005, or 13.8% mainly due to the IP divestment as outlined above. Retail volumes marketed on the Agip branded network (8.66 mmtonnes) decreased of some 90 ktonnes, down 1%, due to a higher competitive pressure. This decline essentially concerned gasoline and BluDiesel, following a pattern aligned with national consumption trends. Market share of the Agip branded network was down 0.4 percentage points from 29.7% to 29.3% in 2006; average throughput in terms of gasoline and diesel fuel was 2,463 kliters, down 1.8% from 2005. At December 31, 2006, Eni’s retail distribution network in Italy consisted of 4,356 service stations, seven more than at December 31, 2005 (4,349 units), resulting from the opening of new service stations (20 units) and the positive balance of acquisitions/releases of lease concessions (11 units), offset in part by the closing of service stations with low throughput (21 units) and the release of 3 service stations under highway concessions. Retail volumes of BluDiesel – a high performance and low environmental impact diesel fuel – amounted to about 726 ktonnes (840 mmliters), down 14.8% from 2005, mainly due to an increasingly high sensitivity of consumers to retail prices of fuels in light of their escalation that pushed prices to historical peaks. At year-end, virtually all Agip branded service stations marketed BluDiesel (about 4,061 equal to 93%). Retail volumes of BluSuper – a high performance and low environmental impact gasoline – amounted to |  | about 98 ktonnes (114 mm liters), down 9% from 2005, showing a trend similar to the one of BluDiesel. At year-end, service stations marketing BluSuper totaled 2,316 (1,719 at December 31, 2005) corresponding to approximately 53% of Eni’s network. In 2006, Eni continued its Do-It-Yourself campaign which allows participating customers to obtain discounts or gifts (under agreements with Vodafone and Coop) in proportion to volumes of fuel purchased at self-service outlets, charged on an electronic card. Further bonuses are offered to the most faithful customers. At year-end, the number of active cards was approximately 3.9 million; turnover on cards increased by 3% from 2005. Volumes of fuel marketed under this initiative represented some 39% of total volumes

marketed on the Agip branded outlets joining the campaign, and some 31% of overall volumes marketed on the Agip network. Retail sales outside Italy In recent years, Eni’s strategy focused on selectively growing its market share, by means of acquisition of assets in European areas with interesting profitability perspectives, mainly in Central-Eastern Europe (in particular Southern Germany, Austria, the Czech Republic and Hungary), in South-Eastern France and the Iberian Peninsula. In pursuing such growth, Eni has been able to reap synergies in these areas facilitated by their proximity to Eni’s production and logistic facilities. Over the last five years, retail volumes of refined products marketed in the rest of Europe have grown more than 50% (equal to a compound average growth rate of 9%). In 2006, retail sales were 3.82 mmtonnes, up 150 ktonnes from 2005, or 4.1%, particularly in Germany, Spain and Austria due to the ramp-up of new stations purchased or built with higher throughput than the average level of Eni’s network, while a few less efficient outlets were dismissed. Volume growth was driven primarily by increased sales of diesel fuel and LPG, while gasoline volumes declined. At December 31, 2006, Eni’s retail distribution network |  | in the rest of Europe consisted of 1,938 units, an increase of five units from December 31, 2005. The network’s evolution was as follows: (i) 31 service stations were acquired in Austria and France; (ii) 24 new outlets were opened in Spain and Austria; (iii) 46 low throughput service stations were closed in Spain and France; (iv) a negative balance of acquisitions/releases of lease concessions (down four units) was recorded, with negative changes in Portugal and Germany, positive ones in France and Spain. Average throughput (2,486 kliters) was up 2.4%. Wholesale and other sales Sales volumes on wholesale markets in Italy (10.06 mmtonnes) were down 0.42 mmtonnes from 2005, or 4%, reflecting mainly a decline in domestic consumption related to mild weather conditions in the fourth quarter of the year, with higher temperatures than the seasonal average. This decline mainly involved heating oil and fuel oil, as sales of the latter were also negatively impacted by a process of progressive substitution of fuel oil by natural gas as feedstock for power plants. Instead, jet fuel volumes increased from a year ago reflecting a recovery in the airline industry. Sales on wholesale markets outside Italy (4.60 mmtonnes) increased 100 ktonnes, or 2.2%, mainly due to higher sales of diesel fuel in Germany and Spain.

ENI ANNUAL REPORT / OPERATING REVIEW

Other sales (21.38 mmtonnes) increased by 1.52 mmtonnes, or 7.7%, mainly due to supplies to IP (up 1.3 mmtonnes) despite its divestment in September 2005, and to sales to oil companies and traders (up 220 ktonnes). Supplies of feedstock to the petrochemical industry (2.61 mmtonnes) declined by 460 ktonnes as a consequence of an accident that occurred at the Priolo refinery where Eni had a processing contract to produce feedstock for its nearby petrochemical complex. This agreement expired on December 31, 2006. |  | Capital expenditure In 2006, capital expenditure in the Refining & Marketing segment amounted to euro 645 million and concerned: (i) refining, supply and logistics (euro 376 million) in Italy, aiming at improving flexibility and yields of refineries, in particular the start-up of construction of a new hydrocracking unit at the Sannazzaro refinery; (ii) upgrade and restructuring of the retail network in Italy (euro 125 million), including construction of new outlets; (iii) upgrade of the retail network in the rest of Europe (euro 98 million), including purchase and realization of new outlets, and, to a lesser extent, restructuring of existing ones.

ENI ANNUAL REPORT / OPERATING REVIEW

Sales - production - prices In 2006, sales of petrochemical products (5,276 ktonnes) decreased by 100 ktonnes from 2005, down 1.9%. Main declines concerned: (i) basic petrochemicals (down 4.6%), due to lower product availability as a consequence of the outage of the Priolo cracker due to an accident occurred at the nearby refinery; (ii) elastomers (down 2.3%), due to a slow recovery of the Ferrara and Ravenna plant performance after maintenance activities carried out in the first half of the year; (iii) intermediates (down 10.4%), due to a weak demand. These negatives were offset in part by increased sales of polyethylene (up 3.2%) and aromatics (in particular, xylenes up 4.8%) reflecting good market conditions. Production (7,072 ktonnes) declined by 209 ktonnes from 2005, down 2.9%, in particular in elastomers, polyethylene and basic petrochemicals, where lower production due to the standstill of the Priolo cracker was offset in part by higher production at the Porto Marghera, Sarroch and Dunkerque plants. Styrene |  | production also increased reflecting poor performance in 2005 affected by plant outages and technical issues. Nominal production capacity was in line with 2005. Rising nominal capacity in a few crackers was offset in part by the outage of the Priolo cracker and related plants. Average plant utilization rate calculated on nominal capacity declined by 2 percentage points from 78.4% to 76.4%, mainly due to lower production volumes. Approximately 35.2% of total production was directed to Eni’s own productions cycle (35.8% in 2005). Oil-based feedstock supplied by Eni’s Refining & Marketing Division covered 10% of requirements (23% in 2005). Prices of Eni’s main petrochemical products increased on average by 12%; all business areas posted increases. The most relevant increases were registered in: (i) olefins (up 16.5%), in particular ethylene and propylene; (ii) aromatics (up 19.6%), in particular xylenes; (iii) polyethylene (up 12%) with increases in all products; (iv) styrenes (up 8.2%), in particular styrene and polystyrenes; (v) elastomers (up 4.2%), in particular BR and TPR rubbers.

ENI ANNUAL REPORT / OPERATING REVIEW

Business areas Basic petrochemicals Sales of basic petrochemicals of 2,882 ktonnes declined by 256 ktonnes from 2005, down 4.6%, mainly due to the outage of the Priolo cracker. Declines were registered in olefins (down 1.5%), intermediates (down 10.4%) and benzene (down 23%). Increasing sales in xylene (up 4.8%) and ethylene (up 3.2%) reflected higher product availability at other plants. Basic petrochemical production (4,275 ktonnes) decreased by 175 ktonnes, down 3.9%. Lower production resulting from the Priolo cracker outage was offset in part by higher production at the Porto Marghera and Dunkerque. Styrene and elastomers Styrene sales (587 ktonnes) were slightly higher from 2005 (up 1.1%). Increasing sales in styrene reflected higher production availability. Declines were registered in compact polystyrene (down 1.5%) due to a lack of feedstock owing to the outage of the Priolo cracker and in ABS/SAN due to the outage of the EniPower power station with a negative impact on the Mantova plant. Elastomers sales (413 ktonnes) increased by 1.2% from 2005 excluding the impact of the shutdown of the Champagnier plant in the second half of 2005. Increases concerned all products, with the exception of BR rubbers (down 8%) due to a maintenance standstill of the Ravenna Neocis plant. |  | Styrene production (1,088 ktonnes) increased by 3.8% reflecting mainly technical issues and a maintenance standstill that occurred at the Mantova plant in 2005. Elastomer production (457 ktonnes) decreased by 1.3% excluding the impact of the shutdown of the Champagnier plant, due to a weak demand in BR (down 8.5%) and SBR (down 3.6%) rubbers. Production volumes of other rubbers increased in line with trends registered in demand. Polyethylene Polyethylene sales (1,394 ktonnes) were up 43 ktonnes or 3.2%, from 2005, reflecting positive market conditions for LLPDE (up 9.3%) and HPDE (up 1.5%). These increases were offset by a decline in EVA (down 3.7%) due to certain technical issues at the Oberhausen plant. Production (1,252 ktonnes) declined by 57 ktonnes, or 4.4%, mainly due to the standstill of the Priolo cracker and related plants. Capital expenditure In 2006, capital expenditure (euro 99 million; euro 112 million in 2005) concerned efforts in upkeeping (euro 32 million), improving plant efficiency and streamlining (euro 32 million), environmental protection, safety and environmental regulation compliance (euro 23 million) and extraordinary and periodic maintenance (euro 12 million).

Activity for the year Among the main orders acquired in 2006 were: an EPC contract for Saudi Aramco for the construction of four trains for gas and crude separation with a total capacity of 1.2 mmbbl/d and production facilities within the development of the onshore Khursaniyah field in Saudi Arabia; a contract for the conversion of an oil tanker into an FPSO unit with production capacity of 1.8 mmbbl for the development of the Gimboa field in the deep offshore of Angola for Sonangol P&P; an EPIC contract for Burullus Gas Co for the construction of underwater systems for the development of eight new wells within the expansion plan of the Scarab/Saffron and Simian fields offshore the Nile Delta; |  | a 16-month long contract for the use of the semisubmersible drilling platform Scarabeo 7 in Nigeria for ExxonMobil. Orders acquired amounted to euro 11,172 million, of these projects to be carried out outside Italy represented 91%, while orders from Eni companies amounted to 24% of the total. Eni’s order backlog was euro 13,191 million at December 31, 2006 (euro 10,122 million at December 31, 2005). Projects to be carried out outside Italy represented 90% of the total order backlog, while orders from Eni companies amounted to 20% of the total. In February 2007, a contract for the construction of a new pipelayer has been signed.

ENI ANNUAL REPORT / OPERATING REVIEW

Capital expenditure In 2006, capital expenditure in the Engineering & Construction segment (euro 591 million) concerned: (i) the conversion of the Margaux tanker ship into an FPSO vessel that will operate in Brazil on the Golfinho 1 field; (ii) maintenance and upgrading of equipment; (iii) fabrication and installation of facilities in the offshore phase of the Kashagan project in Kazakhstan. CEPAV Uno and CEPAV Due Eni holds interests in the CEPAV Uno (50.36%) and CEPAV Due (52%) consortia that in 1991 signed two contracts with TAV SpA for the construction of two railway tracks for high speed/high capacity trains from Milan to Bologna (under construction) and from Milan to Verona (in the design phase). With regard to the project for the construction of the line from Milan to Bologna, an Addendum to the contract between CEPAV Uno and TAV was signed on June 27, 2003, redefining certain terms and conditions of the contract. Subsequently, the CEPAV Uno consortium requested a time extension for the completion of works and an additional payment amounting to euro 800 million. CEPAV Uno and TAV failed to solve this dispute amicably, |  | and on April 27, 2006, CEPAV Uno notified TAV a request for arbitration as provided for under terms of the contract. At the end of 2006, the CEPAV Uno consortium had completed works corresponding to 75% of the total contractual price. With regard to the project for the construction of the tracks from Milan to Verona, in December 2004, CEPAV Due presented the final project, prepared in accordance with Law No. 443/2001 on the basis of the preliminary project approved by an Italian governmental authority (CIPE). As concerns the arbitration procedure requested by CEPAV Due against TAV for the recognition of damage related to TAV’s belated completion of its tasks, in January 2007, the arbitration committee came to a partial decision in support of CEPAV Due confirming the recovery of higher incurred costs for design activities. A technical survey is underway to establish a final evaluation of the compensation as requested by the arbitration committee. A law decree revoking the framework contract for the construction of the Milan-Verona line is due to be published. Rights of the Consortium to recover costs incurred up to date for design activities are expected to be preserved.

Eni's net profit for 2006 was a record euro 9,217 million, up euro 429 million compared to 2005, or 4.9%. This increase reflected a better operating performance (up euro 2,500 million, or 14.9%), partially offset by a higher Group tax rate, which rose from 46.8% to 51.8%. The increase in the Group tax rate was recorded mainly in the Exploration & Production division due to: (i) the Algerian windfall tax on upstream earnings effective as from August 1, 2006 (with an overall impact of euro 328 million, of which euro 149 million pertaining to taxation for |  | the period and euro 179 million pertaining to the deferred tax impact); (ii) an increase in the supplemental tax rate implemented by the British Government, applicable to profit before taxes earned by operations in the North Sea, effective as from January 1, 2006, affecting both current taxation and deferred tax liabilities (with an overall impact of euro 198 million of which euro 107 million, pertaining to taxation for the period and euro 91 million pertaining to the deferred tax impact).

(a) |  | For a definition and reconciliation of reported operating profit and reported net profit to adjusted results, which exclude inventory holding gains/losses and special items, see the paragraph “Reconciliation of reported operating profit and net profit to results on an adjusted basis” pages 66.

Eni's adjusted net profit for the year was up 12.5% to euro 10,412 million. Adjusted net profit is calculated by excluding an inventory holding loss of euro 33 million and special charges of euro 1,162 million (both amounts are net of the related fiscal effect). Special charges for the year were principally related to asset impairments, impacting mainly assets in the Exploration & Production division, environmental provisions, redundancy incentives, risk provisions with respect to certain fines imposed by certain regulatory and antitrust authorities and a deferred tax charge, reflecting the windfall tax levied by the Algerian Government and the supplemental tax rate in the UK, as mentioned above. |  | Return on average capital employed (ROACE) calculated on an adjusted basis for the twelve-month period ending December 31, 2006 was 22.7% (20.5% in 2005). Eni's results benefited from a favorable trading environment, with a higher Brent crude oil price (up 19.8% from 2005) and higher selling margins on petrochemical products. These positives were partially offset by declining refining margins (margin on Brent was down 34.4%). Selling margins on natural gas were underpinned by a favorable trading environment. The euro appreciated by 1% over the dollar.

From January 1, 2006 Eni’s subsidiaries operating in diversified sectors (such as real estate services, insurance and financing intermediation, R&D and training services) are reported in the aggregate “Corporate and financing companies” with the exception of Tecnomare which is reported in the Exploration & Production division (previously all these diversified activities were reported in the aggregate “Other activities”). The “Other activities” aggregate includes only Syndial SpA, a subsidiary which runs minor petrochemical activities and reclamation and decommissioning activities pertaining to certain businesses which Eni exited in past years. In order to allow for comparison, 2005 data has been reclassified accordingly; 2004 data has not been reclassified.

ENI ANNUAL REPORT / FINANCIAL REVIEW

The Group adjusted net profit for the year was supported by the increase reported in the: Exploration & Production division (up euro 1,093 million, or 17.7%), reflecting a better operating performance (up euro 2.860 million) as a result of higher realizations in dollars (oil up 22.4% and natural gas up 17.8%) combined with increased production volumes sold (up 10.2 mmboe). These positives were offset in part by higher operating costs and amortization charges, and increased exploration expenses. Adjusted net profit for the year was also negatively affected by the effects of exchange rates and a higher tax rate (from 51.8 to 53.9%); Gas & Power division (up euro 310 million, or 12.1%), reflecting a better operating performance (up euro 351 million) resulting from higher natural gas selling margins due to a favorable trading environment and the reduced impact of the tariff regime implemented by the Authority for Electricity and Gas with Resolution No. 248/2004. Growth in natural gas sales by consolidated subsidiaries (up 3.14 bcm, or 3.8%) and in volumes transported outside Italy contributed positively. On a negative note, transport activities in Italy posted lower operating results due to the tariff regime enacted by the Authority for Electricity and Gas with Resolution No. 166/2005 and distribution activities suffered from lower volumes. Adjusted net profit for the year was supported by a better performance of certain equity-accounted entities; |  | Engineering & Construction division (up euro 72 million or 22%), reflecting a better operating performance against the backdrop of favorable trends in the demand for oilfield services. These increases were partly offset by lower adjusted net profit reported in the Refining & Marketing division (down euro 316 million, or 33.4%), due to a poor operating performance (down euro 424 million) dragged down by a weak refining environment, the appreciation of the euro over the dollar and the impact of a higher level of planned maintenance activity at refineries. Divisional results were also adversely impacted by the weaker performance of marketing activities in Italy due to lower sales as a consequence of the mild weather conditions of the fourth quarter.

Eni's net sales from operations (revenues) for 2006 were euro 86,105 million, up euro 12,377 million from 2005, or 16.8%, primarily reflecting higher product prices in all of Eni's main operating segments, higher volumes sold of hydrocarbons and natural gas and higher activity levels in the Engineering & Construction division, offset in part by the negative impact of the appreciation of the euro versus the dollar (up 1%). Revenues generated by the Exploration & Production division were euro 27,173 million, up euro 4,642 million, or 20.6%, primarily reflecting higher realizations in dollars (oil up 22.4%, natural gas up 17.8%) and higher oil and gas production sold (up 10.2 mmboe). These positives were partially offset by the appreciation of the euro over the dollar. Revenues generated by the Gas & Power division were euro 28,368 million, up euro 5,399 million, or 23.5%, primarily reflecting increased natural gas prices related in |  | particular to a favorable trading environment, higher natural gas volumes sold by consolidated subsidiaries (up 3.14 bcm, or 3.8%) and higher electricity production sold (up 2.05 TWh, or 9%). Revenues generated by the Refining & Marketing division were euro 38,210 million, up euro 4,478 million, or 13.3%, primarily reflecting higher international prices for oil and refined products. Revenues generated by the Petrochemical division were euro 6,823 million, up euro 568 million, or 9.1%, primarily reflecting an increase in average selling prices. Revenues generated by the Engineering & Construction division were euro 6,979 million, up euro 1,246 million, or 21.7%, primarily reflecting higher activity levels in the Offshore and Onshore construction businesses and a higher utilization rate of vessels and higher tariffs in the Offshore Drilling area.

41,592 |  |  |  |  | 51,918 |  |  | 61,140 |  |  | 9,222 |  |  | 17.8 |

Operating expenses for 2006 (euro 61,140 million) were up euro 9,222 million from 2005, or 17.8%, reflecting primarily: (i) higher prices for oil-based and petrochemical feedstocks and for natural gas, affected also by higher charges related to the climatic emergency of the first quarter of 2006; (ii) higher operating costs in the Exploration & Production division, in particular the increase in operating costs resulted from the higher share of development projects in hostile environments and reflected sector-specific inflation; (iii) higher costs for refinery maintenance. These negative factors were offset in part by the impact of the appreciation of the euro over the dollar. Operating expenses include non recurring charges of euro 239 million in 2006 related essentially to a provision related to fines imposed by certain antitrust and regulatory authorities; in 2005 non-recurring charges of euro 290 million concerned a provision related to a fine levied by the Italian Antitrust Authority. |  | Other special charges included in operating costs in 2006 (euro 390 million) related to environmental provisions (euro 292 million), in particular in Syndial and in the Refining & Marketing division; in 2005 other special items of euro 1,300 million concerned essentially environmental provisions (euro 835 million) recorded in particular in Syndial and in the Refining & Marketing division, and provisions to the risk reserve (euro 379 million) related in particular to insurance charges deriving from the extra premium due for 2005 and for the next five years (assuming normal accident rates) related to the participation of Eni to Oil Insurance Ltd. These higher charges took account of the exceptionally high rate of accidents which occurred in the 2004-2005 two year period. Labor costs (euro 3,650 million) were up euro 299 million, or 8.9%, reflecting primarily higher redundancy incentives (up euro 99 million), ordinary wage trends and higher average workforce outside Italy, in particular in the Engineering & Construction division, partly offset by a reduction in average workforce in Italy.

These increases were offset in part by the decline of the Refining & Marketing division (down euro 424 million, or 34.9%) due to a negative refining trading environment and the impact of longer standstills of refineries due to planned maintenance.

ENI ANNUAL REPORT / FINANCIAL REVIEW

2006 net financial income (euro 161 billion) was up euro 527 million from 2005 when net financial charges of euro 366 were recorded. The increase reflected: (i) the positive change in the fair value evaluation of financial derivative instruments recorded in the profit and loss account instead of being recognized in connection with related assets, liabilities and commitments because |  | Eni's financial derivative instruments do not meet the formal criteria to be assessed as hedging instruments under IFRS; (ii) higher interest income deriving from a higher average availability of cash and cash equivalents offset in part by the impact of higher interest rates on dollar loans (Libor up 1.7 percentage points) and on euro loans (Euribor up 0.9 percentage points).

Net income from investments
The table below sets forth 2006 break-down of net income from investments by division:

| (million euro) |  | Exploration & Production |  | Gas & Power |  | Refining & Marketing |  | Engineering & Construction |  | Group

Effect of the application of the equity method of accounting |  | 28 |  |  | 509 |  |  | 194 |  |  | 66 |  |  | 795 |
Dividends |  | 68 |  |  | 3 |  |  | 26 |  |  |  |  |  | 98 |
Net gains on disposal |  | (6 | ) |  | 21 |  |  |  |  |  |  |  |  | 18 |
Other income (losses) from investments |  | (5 | ) |  | (7 | ) |  |  |  |  |  |  |  | (8 | )
|  | 85 |  |  | 526 |  |  | 220 |  |  | 66 |  |  | 903 |

Net income from investments in 2006 were euro 903 million and concerned primarily: (i) Eni's share of income of affiliates accounted for with the equity method (euro 795 million), in particular affiliates in the Gas & Power and Refining & Marketing divisions. The effects of the equity method of accounting include the gain |  | (euro 73 million net to Eni) recorded by Galp Energia SGPS SA on the sale of regulated assets in the natural gas business to Rede Eléctrica Nacional, classified as special; (ii) dividends received by affiliates accounted for at cost (euro 98 million, of which euro 57 million related to Nigeria LNG); (iii) net gains on disposal (euro 18 million).

The comparison with 2005 data is shown in the table below:

2004 |  | (million euro) |  | 2005 |  | 2006 |  | Change

332 |  |  | Effect of the application of the equity method of accounting |  | 737 |  |  | 795 |  |  | 58 |

287 |  |  | Other income (losses) from investments |  | (27 | ) |  | (8 | ) |  | 19 |
820 |  |  |  |  | 914 |  |  | 903 |  |  | (11 | )

The euro 11 million decrease in net income from investments from 2005 was due essentially to lower gains related in particular to the recording in 2005 of the gain on the sale of Italiana Petroli SpA (euro 132 million), whose effects were offset in part by improved |  | results of operations of affiliates in the Gas & Power division, in particular Unión Fenosa Gas SA and Blue Stream Pipeline Co BV and higher dividends distributed by Nigeria LNG.

Income taxes were euro 10,568 million, up euro 2,440 million from 2005 and reflected primarily higher income before taxes (euro 3,016 million). The 5 percentage point increase in statutory tax rate (from 46.8 to 51.8%) related mainly to: (i) the introduction of a windfall tax on upstream earnings in Algeria effective as from August 1, 2006 (with an overall impact of euro 328 million, of which euro 149 million pertaining to taxation for the period and euro 179 million pertaining to the deferred tax impact); (ii) an increase in the supplemental tax rate implemented by the British Government, applicable to profit before taxes earned by operations in the North Sea, effective as from the |  | beginning of the year, affecting both current taxation and deferred tax (with an overall impact of euro 198 million, of which euro 107 million pertaining to taxation for the period and euro 91 million pertaining to the deferred tax impact); (iii) provisions for the settlement of a tax claim in Venezuela. Adjusted tax rate, which is calculated by excluding special charges, was 48.7% (46% in 2005).

ENI ANNUAL REPORT / FINANCIAL REVIEW

The adjusted operating profit for the year was euro 15,763 million, up euro 2,860 million from one year ago, reflecting higher realizations in dollars (oil up 22.4%, natural gas up 17.8) combined with higher sold production volumes (up 10.2 mmboe or 1.7%). This enhanced operating performance was partly offset by: (i) increased production costs and amortization charges related in particular to the higher cost of developing new fields and maintaining production levels at mature fields and sector specific inflation; (ii) an increased exploration expense; (iii) the effect of the appreciation of the euro over the dollar (approximately euro 155 million). |  | This enhanced operating performance was partly offset by an increase in the adjusted tax rate (up 2.1% from 51.8% to 53.9%), resulting in a euro 1.093 million increase (or 17.7%) in the adjusted net profit for the year. Special charges excluded from the adjusted operating profit were euro 183 million and reflected mineral asset impairments offset in part by gains on the disposal of mineral assets. Special charges excluded from the adjusted net profit also include the deferred tax impact of the windfall tax in Algeria, the supplemental tax rate applicable to profit earned in the North Sea enacted by the British Government and a charge for the settlement of a taxation proceeding against a Venezuelan authority for a combined amount of euro 342 million.

The adjusted operating profit of the Gas & Power division rose by euro 351 million or 9.9% to euro 3,882 million, primarily reflecting: (i) higher selling margins on natural gas against the backdrop of a favorable trading environment; (ii) a lower impact of the tariff regime implemented by the Authority for Electricity and Gas with Resolution No. 248/2004; (iii) a growth in natural gas sales by consolidated subsidiaries (up 3.14 |  | bcm, or 3.8%), in volumes transported outside Italy due to the coming on line of volumes transported through the Greenstream gasline from Libya, and in electricity production sold (up 2.05 TWh, or 9%). These positives were partly offset by a lower operating result from transportation activities in Italy due to the tariff regime enacted by the Authority for Electricity and Gas with Resolution No. 166/2005 and a lower operating result

from distribution activities due to lower volumes. In addition, higher purchase costs were incurred in the first quarter of the year, owing to a climatic emergency. Full year adjusted net profit of euro 2,862 million increased by euro 310 million from 2005 (up 12.1%) and also benefited from the improved performance of certain equity-accounted entities. Special charges for the full year recorded in the operating profit (euro 147 million) included certain non recurring |  | charges pertaining to fines imposed by the Authority for Electricity and Gas, and impairments of certain intangible assets, environmental charges and provisions for redundancy incentives.

The adjusted operating profit for 2006 was euro 790 million, down euro 424 million, or 34.9%, from 2005 reflecting primarily: (i) lower realized refining margins reflecting the unfavorable trading environment and the appreciation of the euro versus the dollar, combined with the impact of longer refinery standstills due to planned maintenance partly offset by the higher profitability of processed crudes; (ii) a decline in the operating performance of Italian marketing activities due to lower volumes sold which were negatively affected by the mild weather conditions registered in the fourth quarter and the |  | divestment of Italiana Petroli carried out in September 2005. On the positive side, marketing activities in the rest of Europe performed well as a result of higher retail margins and higher volumes sold. The adjusted net profit for 2006 was euro 629 million, down euro 316 million, or 33.4%, from 2005, reflecting primarily a decrease in operating profit. Special charges excluded from the adjusted operating profit were euro 256 million, reflecting primarily the impact of a non-recurring charge related to a fine imposed by the Italian Antitrust Authority, and environmental provisions and provisions for redundancy incentives.

(a) |  | Excludes special items.

Adjusted operating profit was euro 219 million, down euro 42 million, or 16.1%, from a year ago, due to lower selling margins on products recorded in the first half of the year. This decline affected all businesses with the exception of polyethylene, owing to increases in the cost of oil-based feedstocks not transferred to selling prices. Results for the year were also negatively impacted by the accident occurred at the Priolo refinery in April resulting in lower |  | product availability. These negative factors were offset in part by the positive effect of Eni's sales mix along with an improved industrial and commercial performance. Special charges excluded from the adjusted operating profit were euro 107 million, reflecting primarily asset impairments, the impact of a non-recurring charge related to a fine imposed by an European antitrust authority, and provisions for risks and redundancy incentives.

This increase was recorded in particular in the following areas: (i) Offshore, due to higher activity in the Caspian region and Nigeria; (ii) Offshore Drilling, due to higher tariffs for the Scarabeo 3 and Scarabeo 5 semi-submersible platforms and higher activity levels |  | of the Perro Negro 5 jack-up and Scarabeo 4 semi-submersible platform; (iii) Onshore due to higher activity related essentially to the start-up of some large projects acquired in 2005. Adjusted net profit of euro 400 million increased by euro 72 million from 2005 (up 22%) due to an enhanced operating performance, offset in part by losses of affiliates.

NON-GAAP Measures
Reconciliation of reported operating profit and net profit to results on an adjusted basis
Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Further, finance charges on finance debt, interest income, charges or income deriving from the fair value evaluation of derivative financial instruments held for trading purposes, and exchange rate differences are excluded when determining adjusted net profit of each business segment.
Taxation effect of such items excluded from adjusted net profit is determined based on the specific rate of taxes applicable to each item, with the exception of finance charges or income, to which the Italian statutory tax rate of 33% is applied.
Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them to facilitate comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment.
The following is a description of items which are excluded from the calculation of adjusted results.
Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold in the period calculated using the weighted-average cost method of inventory accounting.
Special items include certain relevant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past exercises or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non recurring material income or charges are to be clearly reported in the management’s discussion and financial tables.
Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition the effect of the fair value evaluation of derivative financial instruments held for trading purposes and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charges pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of asset retirement obligations in the Exploration and Production division).
Finance charges or interest income and related taxation effects, excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies.
For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and net profit see tables below.

Summarized Group Balance Sheet

Summarized group balance sheet aggregates the amount of assets and liabilities derived from the statutory balance sheet in accordance with functional criteria which consider the enterprise conventionally divided into the three fundamental areas focusing on resource investments, operations and financing. Management believes that this summarized group balance sheet is useful information in assisting investors |  | to assess Eni's capital structure and to analyze its sources of funds and investments in fixed assets and working capital. Management uses the summarized group balance sheet to calculate key ratios such as return on capital employed (ROACE) and the proportion of net borrowings to shareholders' equity (leverage) intended to evaluate whether Eni's financing structure is sound and well-balanced.

The appreciation of the euro over other currencies, in particular the dollar (at December 31, 2006 the EUR/USD exchange rate was 1.317 as compared to 1.180 at December 31, 2005, up 11.6%) determined with respect to year-end 2006, an estimated decrease in the book value of net capital employed of approximately euro 2,200 million, in net equity of approximately euro 1,550 million and in net borrowings of approximately euro 650 million as a result of currency conversions at December 31, 2006. |  | At December 31, 2006, net capital employed totaled euro 47,966 million, representing a decrease of euro 1,726 million from December 31, 2005. Fixed assets (euro 54,234 million) are substantially in line with December 31, 2005 (euro 54,291 million). Provisions for depreciation, amortization and impairments (euro 6,421 million) and the effect of the appreciation of the euro over the dollar in the translation of financial statements of subsidiaries operating with currencies other than the euro (euro 2,200 million) offset capital expenditure for the

period (euro 7,833 million). Property, plant and equipment (euro 44,312 million) were primarily related to the Exploration & Production (51.9%), Gas & Power (31.7%) and Refining & Marketing (8.6%) segments. Provisions for depreciation, amortization and writedowns (euro 49,143 million) represented 52.6% of gross property, plant and equipment (50.4% at December 31, 2005). Other assets included, for a book value of $829 million (corresponding to euro 629 million at the year end EUR/USD exchange rate), the assets related to the service contract for mining activities in the Dación area of the Venezuelan branch of Eni's subsidiary Eni Dación BV. With effective date April 1, 2006, the Venezuelan State oil company Petróleos de Venezuela SA (PDVSA) unilaterally terminated the Operating Service Agreement (OSA) governing activities at the Dación oil field where Eni acted as a contractor, holding a 100% working interest. As a consequence, starting on the same day, operations at the Dación oil field are conducted by PDVSA. Eni proposed to PDVSA to agree on terms in order to recover the fair value of its Dación assets. On November 2006, Eni commenced a proceeding before an International Centre for Settlement of Investment Disputes (ICSID) Tribunal (i.e. a tribunal acting under the auspices of the ICSID Convention and being competent pursuant to the Treaty) to claim its rights. In fact, a bilateral investments treaty is in place between the Netherlands and Venezuela (the “Treaty”), Despite this action, Eni is still ready to negotiate a solution with PDVSA to obtain a fair compensation for its assets. Based on the opinion of its legal consultants, Eni believes to be entitled to a compensation for such expropriation in an amount equal to the market value of the OSA before the expropriation took place. The market value of the OSA depends upon its expected profits. In accordance with established international practice, Eni has calculated the OSA’s market value using the discounted cash flow method, based on Eni’s interest in the expected future hydrocarbon production and associated capital |  | expenditures and operating costs, and applying to the projected cash flow a discount rate reflecting Eni’s cost of capital as well as the specific risk of concerned activities. Independent evaluations carried out by a primary petroleum consulting firm fully support Eni’s internal evaluation. The estimated net present value of Eni’s interest in the Dación field, as calculated by Eni, is higher than the net book value of the Dación assets which consequently have not been impaired. In accordance with the ICSID Convention, a judgement by the ICSID Tribunal awarding compensation to Eni would be binding upon the parties and immediately enforceable as if it were a final judgement of a court of each of the States that have ratified the ICSID Convention. The ICSID Convention was ratified in 143 States. Accordingly, if Venezuela fails to comply with the award and to pay the compensation, Eni could take steps to enforce the award against commercial assets of the Venezuelan Government almost anywhere those may be located (subject to national law provisions on sovereign immunity). At December 31, 2006, net working capital totaled euro 5,197 million, representing a decrease of euro 1,629 million from December 31, 2005 mainly due to: (i) an increase in taxes payable and the reserve for net deferred tax liabilities, reflecting primarily the recording of deferred tax liabilities for the period; (ii) an increase in the reserve for contingencies, due to the evaluation review of the site restoration and abandonment reserve (in particular in the Exploration & Production division), the risk provisions with respect to certain fines imposed by certain regulatory and antitrust authorities, environmental charges and provision for redundancy incentives. Commercial working capital (inventories and trade accounts receivable/payable) was substantially in line with the value recorded in 2005. The share of the Exploration & Production, Gas & Power and Refining & Marketing divisions on net capital employed was 89.9% (90.9% at December 31, 2005).

Return On Average Capital Employed (ROACE)

Return on Average Capital Employed for the Group, on an adjusted basis is the return on Group average capital invested, calculated as the ratio between net adjusted profit before minority interests, plus net finance charges on net borrowings, less the related tax effect and net average capital employed. The tax rate applied on finance charges is the Italian statutory tax rate of 33%. The capital invested as of period-end used for the calculation of net average |  | capital invested is obtained by deducting inventory gains or losses as of in the period, rectified from the related tax effect. ROACE by business segment is determined as the ratio between adjusted net profit and net average capital invested pertaining to each business segment and rectifying the net capital invested as of period-end, from net inventory gains or losses (after applying the business segment specific tax rate).

Net borrowings and leverage

Leverage is a measure of a company's level of indebtedness, calculated as the ratio between net borrowings which is calculated by excluding cash and cash equivalents and certain very liquid assets from financial debt and shareholders' equity, including minority interests. Management makes use of leverage in order to assess the soundness and efficiency of the |  | Group balance sheet in terms of optimal mix between net borrowings and net equity, and to carry out benchmark analysis with industry standards. In the medium term, management plans to maintain a strong financial structure targeting a level of leverage up to 0.40.

ENI ANNUAL REPORT / FINANCIAL REVIEW

Net borrowings at December 31, 2006 were euro 6,767 million, representing a decrease of euro 3,708 million from December 31, 2005 due mainly to cash inflow generated by operating activities (euro 17,001 million). Currency translation effects also contributed to the reduction in net borrowings. Debts and bonds amounted to euro 11,699 million, of which euro 4,290 million were short-term (including the portion of long-term debt due within 12 months for euro 890 million) and euro 7,409 million were long-term. |  | At December 31, 2006, leverage was 0.16, compared with 0.27 at December 31, 2005. Net borrowings increased by euro 2,917 million from September 30, 2006 (euro 3,850 million) as cash inflow generated by operating activities (euro 1,780 million) partially covered the financial requirements for capital expenditure and investments amounting to euro 2,963 million, the payment of an interim dividend for fiscal year 2006 by the parent company Eni SpA (euro 2,210 million) and the repurchase of own shares for euro 105 million.

Shareholders’ equity at December 31, 2006 (euro 41,199 million) was up euro 1,982 million from December 31, 2005, due primarily to net profit before minority |  | interest (euro 9,823 million), offset in part by the payment of Eni's 2005 dividends, the purchase of own shares and currency translation effects.

Summarized cash flow statement and change in net borrowings

Eni's summarized group cash flow statement derives from the statutory statement of cash flows. It allows to create a link between changes in cash and cash equivalents (deriving from the statutory cash flows statement) occurred from the beginning of period to the end of period and changes in net borrowings (deriving from the summarized cash flow statement) occurred from the beginning of period to the end of period. The measure enabling to make such a link is represented by free cash flow which is the cash in |  | excess of capital expenditure needs. Starting from free cash flow it is possible to determine either: (i) changes in cash and cash equivalents for the period by adding/deducting cash flows relating to financing debts/receivables (issuance/repayment of debt and receivables related to financing activities), shareholders' equity (dividends paid, net repurchase of own shares, capital issuance) and the effect of changes in consolidation and of exchange differences; (ii) changes in net borrowings for the period by adding/deducting cash flows relating to shareholders' equity and the effect of changes in consolidation and of exchange differences.

Other Information

Court inquiries The Milan Public Prosecutor is inquiring into contracts awarded by Eni’s subsidiary EniPower and on supplies from other companies to EniPower. The media has widely covered these inquiries. It emerged that illicit payments were made by EniPower suppliers to a manager of EniPower who was immediately dismissed. The Court presented EniPower (commissioning entity) and Snamprogetti (contractor of engineering and procurement services) with notices of process in accordance with existing laws regulating administrative responsibility of companies (Legislative Decree No. 231/2001). In its meeting of August 10, 2004, Eni’s Board of Directors examined the above mentioned situation and Eni’s CEO approved the creation of a task force in charge of verifying the compliance with Group procedures regarding the terms and conditions for the signing of supply contracts by EniPower and Snamprogetti and the subsequent execution of works. The Board also advised divisions and departments of Eni to fully cooperate in every respect with the Court. From the inquiries performed, no default in the organization emerged, nor deficiencies in internal control systems. External experts have performed inquiries with regard to certain specific aspects. In accordance with its transparency and firmness guidelines, Eni will take the necessary steps in acting as plaintiff in the expected legal action in order to recover any damage that could have been caused to Eni by the illicit behavior of its suppliers and of their and Eni employees. In the meantime, preliminary investigations have found that both EniPower and Snamprogetti are not to be considered defendants in accordance with existing |  | laws regulating administrative responsibility of companies (Legislative Decree No. 231/2001). An investigation is pending regarding two former Eni managers who were allegedly bribed by third parties in order to favor the closing of certain transactions with two oil product trading companies. Within such investigation, on March 10, 2005, the public prosecutor of Rome notified Eni two judicial measures for the seizure of documentation concerning Eni’s transactions with said companies. Eni is acting as plaintiff in this proceeding. TSKJ Consortium - Investigations of SEC and other Authorities In June 2004 the U.S. Securities and Exchange Commission (SEC) notified a request of collaboration on a voluntary basis to Eni, which Eni promptly carried out, in order to obtain information regarding the TSKJ consortium in relation to the construction of natural gas liquefaction facilities at Bonny Island in Nigeria. The TSKJ consortium is formed by Snamprogetti (Eni 43.54%) with a 25% interest and, for the remaining part, by subsidiaries of Halliburton/KBR, Technip and JGC. The SEC investigations concern alleged improper payments made by the TSKJ consortium to certain public officials. Eni’s subsidiary Snamprogetti is conducting its own investigations on those alleged improper payments. Other authorities are currently investigating this matter. Eni and its subsidiary Snamprogetti are currently providing documentation and information to the SEC and other authorities, providing the necessary support.

Subsequent events Main subsequent events are reported in the Operating Review above. Business trends The outlook for Eni in 2007 remains positive, with key business trends for the year as follows: production of liquids and natural gas is forecast to remain on the same level as 2006 (1.77 mmboe/d). Mature field decline in Italy and in the North Sea is expected to be offset by a growth in Libya, due to the build-up of the Western Libyan Gas Project; sales volumes of natural gas are forecast to increase from 2006 levels (97.48 bcm), increases are expected in the Iberian Peninsula, German/Austrian and French markets; sold production of electricity is expected to increase from 2006 levels (24.82 TWh) due to the ramp-up of production capacity in Brindisi and the planned start-ups of new capacity at the Ferrara power plant; |  | refining throughputs on Eni’s account are forecast to decline slightly from 2006 (38.04 mmtonnes), due to the termination of the contract for processing certain volumes of crude at the Priolo refinery’s facilities owned by a third party, to be offset by higher throughputs expected at the Gela, Livorno and Sannazzaro refineries; retail sales of refined products are expected to slightly increase in Italy due to planned marketing initiatives, and in the rest of Europe due to new acquisitions of service stations in target markets. In 2007, management expects to increase capital expenditure from the 2006 level (euro 7.83 billion). Increases will be apportioned to the development of oil and natural gas reserves, upgrading of refineries and the retail network and upgrading of natural gas import and transport infrastructure.

ENI ANNUAL REPORT / CORPORATE GOVERNANCE

Corporate Governance

Code of Conduct The Board of Directors of Eni has deemed it appropriate to provide a clear definition of the value system that Eni recognizes, accepts and upholds and the responsibilities that Eni assumes within its Group and externally in order to ensure that all Group activities are conducted in compliance with laws, in a context of fair competition, with honesty, integrity, correctness and in good faith, respecting the legitimate interests of shareholders, employees, suppliers, customers, commercial and financial partners and the communities where Eni operates. All those working for Eni, without exception or distinction, are committed to observing these principles within their function and responsibility and to ensure that others observe them. The belief of working for the advantage of Eni is not a justification for behaviours contrary to such principles. These values are stated in a Code of Conduct whose observance by employees is evaluated by the Board of Directors, based on the annual report of the Guarantor for the Code of Conduct. The Code of Conduct is published on Eni’s website www.eni.it. Self-discipline Code In its meeting of January 20, 2000, Eni’s Board of Directors resolved to adopt the first “Self-discipline Code of Listed Companies” published by Borsa Italiana SpA and underscored how Eni’s organizational model is essentially in line with the principles expounded in the Code, as well as with related recommendations issued by Consob. In its meeting of December 13, 2006, the Board of Directors decided to conform to the Code of Conduct |  | for listed companies, as issued by Borsa Italiana in March 2006 (“Borsa Italiana Code”) by adopting an Eni Code (the “Code”). The Eni Code is based on the Borsa Italiana Code and adapts certain recommendations of the Borsa Italiana Code to the specific circumstances of Eni, clarifying certain others which resulted in a further improvement of Eni’s corporate governance. The aim of the Code is to clearly and fully disclose Eni’s corporate governance system. The Code takes into consideration the fact that Eni is a parent company, is not controlled by any other company and – in the light of the recent provisions of the companies law reform – is not subject to direction and co-ordination by any Italian or foreign entity (company or body); hence, all the principles expounded in the Borsa Italiana Code not consistent with this status have been adjusted to avoid misunderstanding among Eni’s shareholders and stakeholders. Similarly, the By-Laws currently in force foresee a traditional administration and control model (removing the possibility to adopt a one-tier or a two-tier model of management and control system as foreseen in the Borsa Italiana Code), the separation of the positions held by the Chairman and the CEO (making the appointment of a lead independent director unnecessary), and specific rules on the appointment and composition of the Board of Directors and of the Board of Statutory Auditors. The Eni Code directly makes specific choices where the Borsa Italiana Code leaves this option to listed companies, making further amendments unnecessary and guaranteeing more transparency and

understanding (i.e., the choice not to re-allocate or modify the Board’s internal committees functions, the choice to entrust internal control responsibilities to only one managerial position, to require the internal control manager to refer to the CEO and the choice not to entrust internal auditing activities to third parties). Certain principles regarding Shareholders’ Meeting’s duties proposed by the Borsa Italiana Code were merely indicated or suggested by the Board of Directors that cannot inpose decisions to the Shareholders' Meeting. All this notwithstanding, the Board is committed to ensure that the Shareholders and the Shareholders’ Meeting focus a fair deal of attention on such issues, or otherwise promote integrations to Eni By-laws. Certain generic recommendations of the Borsa Italiana Code have been specified in the Eni Code, in particular criteria regarding the independence of directors by clearly wording the definition of “supplementary remuneration”, which jeopardizes the independence requirement, and the meaning of “close relatives”. The Eni Code establishes certain principles that enhance the level of governance suggested by the Borsa Italiana Code; in particular: the directors have adopted a guideline which takes into consideration the interests of all stakeholders when pursuing the objective of creating value for the Company’s shareholders; the minimum frequency of the information to be supplied to the Board of Directors by the directors holding proxies has been reduced to two months as compared with the minimum three-month period envisaged by the Borsa Italiana Code; the Board’s self-evaluation can be performed with the support of a specialized external consultant, to ensure its objectiveness; directors and auditors shall hold their positions only as long as they deem to be able to devote the necessary time to diligently perform their duties; the number of members of Board committees shall be lower than the majority of Board members in order not to interfere with the Board’s decision-making process; the Internal Control Committee’s opinion on corporate rules has been introduced, ensuring that all transactions carried out with related parties and transactions in which a director has an interest, are performed in a transparent way and according to the criteria of substantial and procedural fairness; the proposal of appointment of the manager delegated to internal control to the Board of Directors is drafted by the CEO, in agreement with the Chairman; |  | at least two members of the Internal Control Committee must have adequate experience in accounting and finance (the Borsa Italiana Code foresees only one member with these skills). The Board of Statutory Auditors was invited to expressly agree to the provisions of the Borsa Italiana Code on the Board of Statutory Auditors, and promptly adhered during their December 13, 2006 meeting. In its meeting of December 13, 2006, the Board of Directors approved several rules regarding the implementation and specifying the provisions of the Code; in particular: the tasks of the Board of Directors have been redefined: the Board maintains an absolute central role in Eni’s corporate governance system, with wide responsibilities that cover also Eni and its subsidiaries’ organization; the most important transactions of Eni and its subsidiaries, that require the approval of the Board of Directors, have been defined; the Board of Directors has a central role in defining sustainability policies and approving the sustainability report submitted also to the Shareholders’ Meeting; the subsidiaries with strategic relevance have been identified; the Board of Directors has expressed its position on the admissible maximum number of positions in other companies that can be held by Eni’s directors to ensure a sufficient amount of time for the effective performance of their duties; the principle of the respect of managerial autonomy of subsidiaries that are also listed on a regulated market (as Saipem and Snam Rete Gas) has been expressly stated as well as Eni’s commitment to observing such principles as defined in the Borsa Italiana Code regarding persons holding significant positions in the share capital of listed companies. In its meeting of March 16, 2007, the Board of Directors implementing the prescriptions of the Code and with the positive opinion of the Internal Control Committee, entrusted the Internal Audit Manager as manager delegated for the Internal control. In its meeting of March 29, 2007, the Board of Directors approved changes in the regulations regarding the functioning and the tasks of the Internal Control Committee and the Compensation Committee, to align them to the prescriptions of the Eni Code. * * *

Eni’s corporate governance model, therefore, complies with the provisions of the Borsa Italiana Code and foresees certain provisions intended to improve the level of corporate governance. In relation to the compliance with the recommendations of the Code, the only items still to be implemented, but currently under realization, deal essentially with: the editing of a procedure for transactions with related parties, waiting for the issuing of general principles which Article 239-bis of the Civil Code assigns to Consob. Pending the publication of such rules by Consob, Eni’s internal rules provide that transactions with related parties are submitted to the Board of Directors, even when amounting to less than the materiality threshold set for the transactions to be approved by the Board; the alignment of the number of members of Board Committees which, as foreseen by the Eni Code, should not represent the majority of Board’s members. Eni’s Code of Conduct has been published on Eni’s website. The “Comment” present in the Borsa Italiana Code has not been included, in order to not lengthen the document, however Eni took it into account in the implementation of principles and criteria. * * * In accordance with the requirements and indications of Borsa Italiana SpA, in particular, the “Guidelines for the preparation of the yearly report on corporate governance” of February 12, 2003, follows information on Eni’s corporate governance system. The “Guide to the preparation of the report on corporate governance” published by Assonime and Emittenti Titoli SpA in March 2004 has also been taken into account in preparing this report. Eni’s organizational structure Eni’s organizational structure follows the traditional model of companies in which management is entrusted exclusively to the Board of Directors, which is the central element of Eni’s corporate governance system. Monitoring functions are entrusted to the Board of Statutory Auditors and accounting control is entrusted to external auditors appointed by the Shareholders’ Meeting. According to Article 25 of Eni’s By-laws, the Chairman and the CEO represent the company. The Board of Directors established committees with consulting and proposing functions. |  | The Board of Directors Competencies On June 1, 2005, the Board of Directors appointed Mr. Paolo Scaroni as Chief Executive Officer and delegated all necessary powers for the administration of the Company to him, with the exception of those powers that cannot be delegated in accordance with current legislation (Article 2381 of the Italian Civil Code) and those retained by the Board of Directors (as amended by the Board of Directors in its meeting of October 11, 2005). As mentioned above, in its meeting of December 13, 2006, the Board of Directors modified these resolutions in order to update their contents to the Code’s prescriptions, implement a more effective coordination with the By-laws and entrust the Board of Directors with a central role in the Group’s sustainability policies. The Board, in accordance to these rules, retained the following powers, in addition to those that cannot be delegated under applicable laws: 1. Establishes the Company and Group Corporate Governance system and rules. In particular, after consulting the Internal Control Committee, the Board approves the rules that ensure the substantial and procedural transparency and correctness of the transactions carried out with related parties and those in which a director holds an interest, on his behalf or on behalf of third parties. The Board adopts a procedure for the management and disclosure to third parties of documents and information concerning the Company, having special regard to price sensitive information. 2.

Board’s opinion on the matter of the admissible number of positions held by directors in other companies In its meeting of December 13, 2006, the Board of Directors expressed its opinion on the matter of the admissible number of positions held by directors in other companies, as required by Eni’s Self-discipline Code: an executive director should not hold: i) the position of executive director in any other Italian or foreign listed company, or in any finance, banking or insurance company or any company with a net equity exceeding euro 10 billion and ii) the position of non-executive director or statutory auditor (or member of any other advisory committee) in more than three of said companies; a non-executive director, should not hold further positions than the one held in Eni, as: i) executive director in more than one of the companies mentioned above and non-executive director or statutory auditor (or member of any other control body) in more than three of the mentioned companies, or as ii) non-executive director or statutory auditor in more than six of the mentioned companies. All the positions held in Eni’s subsidiaries are excluded for the purposes described above. In case a director exceeds said limits in terms of positions held, he should timely inform the Board, who shall judge the situation taking into account the interest of the Company and call upon the interested director to make a decision on the matter. |  | On the basis of available information, Eni’s directors comply with these limits on the number of positions held in other companies. Independence and honorability Legislative Decree No. 58 of February 24, 1998 (TUF), as amended by Legislative Decree No. 303 of December 29, 2006 states that at least two members in a Board composed by more than seven members must possess the independence requirements provided for Statutory Auditors of listed companies. Article 17.3 of Eni’s By-laws states that at least three Board members shall have the independence requirement, in case the Board is made up by more than five members. This rule actually increases the number of independent directors in Eni’s Board. Eni’s Code foresees further independence requirements, in line with the ones provided by the Borsa Italiana Code. On February 22, 2007, Eni’s Board of Directors, in accordance with the provisions of Eni’s By-laws and Code, determined that six out of its nine members are independent, specifically: non-executive Directors Alberto Clô, Renzo Costi, Dario Fruscio, Marco Reboa, Mario Resca and Pierluigi Scibetta. Renzo Costi was confirmed to be independent notwithstanding his permanence as board member for a period longer than nine years, due to the fact that he has been nominated by minority shareholders (specifically institutional investors) and has demonstrated ethical and professional qualities and independence when expressing his opinion during this period. The Board of Statutory Auditors verified the proper application of criteria and procedures adopted by the Board to evaluate the independence of its members. In accordance with the TUF, implemented in Article 17.3 of Eni’s By-laws, the Directors and General Managers of listed companies shall possess the honorability requirements prescribed for statutory auditors. On February 22, 2007, the Board of Directors verified that all its members possess the honorability requirements. In accordance with Article 17.3 of Eni’s By-laws, should the independence and honorability requirements be impaired or cease or the minimum number of independent Directors diminish below the threshold set by Eni’s By-laws, the Board declares the termination of office of the member lacking said requirements and provides for his substitution. Meetings and functioning In 2006, the Board of Directors met 16 times (21 in 2005) for an average duration of three hours.

The financial calendar is available on Eni’s website. In its meeting of June 1, 2005, the Board of Directors defined the rules for the calling of its meetings; in particular, the Chairman convenes Board meetings, and, in agreement with the CEO, defines agenda items. Notice is sent to the Directors, Statutory Auditors and the Magistrate of the Court of Accounts, by mail, fax, or e-mail within five days of the meeting’s date, at least 24 hours in advance in case of urgency. Eni’s By-laws allow meetings to be held by video or teleconference. Board members, Statutory Auditors and the Magistrate of the Court of Accounts receive in advance adequate and thorough information on all issues subject to Board evaluation and resolutions, except when confidentiality is deemed necessary. During meetings directors can meet managers of Eni and its subsidiaries in order to obtain information on specific matters of the agenda items. In 2006, on average 85% of Board members participated to Board meetings and 84% of independent non-executive Board members. In the attached table, the percentage of attendance of each member of the Board to the Board of Directors’ and Board committees’ meetings is presented. On September 21, 2006, the Board of Directors’ meeting was held on the Sabratha platform, off the Libyan coast, to allow non-executive directors to increase their knowledge on how Eni’s businesses operate. Until this date, non-executive and independent members have always met in presence of the other members of the Board; Eni’s By-laws allow them to decide whether it is necessary to hold meetings attended exclusively by non-executive and independent members. Board self evaluation The Board of Directors performed its first evaluation of size, composition and functioning of the Board itself, in accordance with Eni’s and Borsa Italiana Codes. In accordance with Eni’s Code, the Board of Directors has received support by a specialized consulting firm, Egon Zehnder, to guarantee the objectiveness of its evaluations. Egon Zehnder’s work was focused on: a) gaining insight on the level of functioning and efficiency of the Board; |  | b) identifying areas of improvement or weakness in the functionality and efficiency of the Board. Consultants performed an in-depth interview of each member and analyzed the quantitative and qualitative aspects of all the information obtained. The results of the interviews performed by Egon Zehnder were presented to the Board of Directors, being present the Board of Statutory Auditors. In its meeting of February 22, 2007, the Board reviewed the findings of the consultant and judged the size, composition and functioning of the Board and of the committees of the Board to be substantially positive. This conclusion shared by the consultant. The main qualifying items underlined by the Board of Directors are: the open and direct discussion during the meetings; the respect for the contribution of each member; a constructive approach on part of all Board members to reach consensual solutions; the completeness, transparency and timeliness of information prepared by the CEO for Board meetings, and of explanations provided by the CEO during the meetings in order to allow the Board to perform its role being well informed and aware of the issues on the agenda. All Directors have agreed on the personal contribution of each member to the optimization of the reviews made by the Board, thus allowing the Board to fully benefit from the different skills and professional backgrounds of each member, resulting in a more informed and consensual influence on the resolutions of the Board. The Directors also agreed upon holding informal meetings to gain more insight on specific managerial and business matters, in order to better perform assigned duties. Remuneration Board members’ emoluments are determined by the Shareholders’ Meeting, while the emoluments of the Chairman and CEO, in relation to the powers attributed to them, are determined by the Board of Directors, based on proposals of the Compensation Committee and after consultation with the Board of Statutory Auditors. On May 27, 2005 the Shareholders’ Meeting resolved to determine the annual emolument of the Chairman in euro 265,000 and of Board members in euro 115,000. It also resolved a bonus up to a maximum of euro 80,000 for the Chairman and euro 20,000 for each Board member. The amount of the bonus is determined in accordance with the performance of Eni shares in the reference year as compared with the performance of the seven largest international oil companies for market capitalization.

The share performance takes account of the dividend paid. Said bonus amounts to euro 80,000 or euro 40,000, and euro 20,000 or euro 10,000 for the Chairman and each Board member, respectively, depending on whether the performance of Eni shares is rated first or second, or third or fourth in the reference year, respectively. No bonus is paid in case Eni scores a position lower than the fourth one. In the meeting of June 21, 2006, the Board verified that Eni rated third in the mentioned positioning in 2005. In the meeting of July 27, 2006, the Board of Directors, as proposed by the Compensation Committee and advised by the Board of Statutory Auditors, determined an additional element of remuneration for the Board members holding positions in Board’s committees, with the exclusion of the Chairman and CEO. Said fee amounts to euro 30,000, and euro 20,000 for the position of chairman of a committee and of member of a committee, respectively. This amount decreases to euro 27,000 and euro 18,000 in case a member holds positions in more than one committee. The remuneration of the Chairman is made up of both a fixed emolument and a variable part in relation to the powers delegated to him by the Board. The remuneration of the CEO, the general managers and other managers with strategic responsibilities1 is made up by a salary, a bonus, and a long term incentive. The CEO also earns a fixed emolument and a variable part in relation to the powers delegated to him by the Board. The salary of the three General Managers of Eni divisions and of other key managers is defined considering the position held and their specific responsibilities, taking into account the compensation level adopted by domestic and worldwide companies (in oil and gas, industrial and service sectors) and aligning it on a yearly base considering individual performance and career progression. The variable part of the remuneration is paid yearly, based on the achievement of specific financial, operational and strategic targets and of individual performance goals pertaining to each business or functional unit. The variable part of the Chairman’s and CEO’s remuneration is determined based on the achievement of specific company objectives. The variable part paid in 2006 was determined based on the achievement of Eni’s target for 2005 as approved by the Board of Directors on proposal of the Compensation Committee and defined consistently |  | with the targets of the strategic plan and yearly budget. Said targets include a set level of cash flow from operations (with a 40% weight), profitability (30%) and divisional operating performance (30%). Results achieved have been assessed assuming a constant trading environment and have been verified by the Compensation Committee and approved by the Board of Directors. Based on these results, a variable amount equal to 125% of the target level was determined, within an interval ranging from 85% to 130% of said target level. In March 2006, the Board of Directors approved a new long-term incentive plan for senior managers of Eni and its subsidiaries (excluding listed subsidiaries), as proposed by the Compensation Committee. This new scheme is intended to motivate more effectively and retain managers, linking incentives to targets and performance achieved in a tighter way than previous incentives schemes. This new incentive scheme applies to the 2006-2008 three year period and is composed of a deferred monetary incentive, linked to the achievement of certain business growth and operating efficiency goals, replacing the previous stock grant plan, and of a stock option incentive focused on the achievement of certain targets of total shareholder return. This stock-based incentive was approved by the General Shareholders’ Meeting of May 25, 2006. This scheme has a structure that balances the monetary and stock-based components of the remuneration, as well as links economic and operating performance to share performance in the long term. The deferred monetary incentive assigned in 2006 is paid after three years from the assignment depending on the achievement of the annual EBITDA targets preset for the 2006-2008 period. Results in terms of EBITDA are assessed by comparing actual results with set targets under a constant trading environment for each year. Stock options assigned in 2006 can be exercised after three years from the assignment in a percentage depending on the performance of Eni shares measured in terms of Total Shareholder Return2 as compared to that achieved by a panel of major international oil companies over the 2006-2008 three-year period (see below). At the end of the three year period, the results of the long term incentive plan are analyzed by the Compensation Committee and approved by the Board of Directors. The CEO, being the General Manager of the company,

Stock options and other share-based compensation STOCK GRANTS With the aim of improving motivation and loyalty of the managers of Eni SpA and its subsidiaries as defined in Article 2359 of the Civil Code through the linking of compensation to the attainment of preset individual and corporate objectives, making management participate in corporate risk and motivating them towards the creation of shareholder value and increasing at the same time their contribution to the management of the Company, in 2003 Eni started a stock grant scheme envisaging the offering of its own shares purchased under its buy back program (treasury shares) for no consideration to those managers of Eni |  | who achieve corporate and individual objectives. Said scheme applied to the three year-period 2003-2005. Assignment vested within 45 days after the end of the third year from the date of the offer. Under this stock grant plan, on December 31, 2006, a total of 1,873,600 grants were outstanding for the assignment of an equal amount of treasury shares (equal to 0.05% of capital stock) pertaining to 2003, 2004 and 2005 assignments as follows: (i) a total of 2.500 grants (fair value euro 11.20 per share) related to 2003, (ii) a total of 798,700 grants (fair value euro 14.57 per share) related to 2004 and (iii) a total of 1,072,400 grants (fair value euro 20.08 per share) related to 2005.

ENI ANNUAL REPORT / CORPORATE GOVERNANCE

STOCK OPTIONS Eni offers managers of Eni SpA and its subsidiaries as defined in the Article 2359 of the Civil Code holding positions of significant responsibility for achieving profitability or strategic targets, the opportunity to acquire a shareholding in the company as an element of remuneration through the award of options for purchasing Eni treasury shares. On May 25, 2006, the Sharehoders’ Meeting approved the 2006-2008 stock option plan and authorized the Board of Directors to make available a maximum amount of 30 million treasury shares (equal to 0.749% of the share capital) for the stock option plan. This stock option plan foresees three annual awards. Unlike previous schemes, the 2006-2008 stock option plan introduced a performance condition upon which options can be exercised. At the end of each vesting period with a three-year duration, the Board of Directors determines the number of exercisable options, in a percentage ranging from 0% to 100% of the total amount awarded for each year of the plan, depending on the performance of Eni shares measured in terms of Total Shareholder Return as compared to that achieved by a panel of major international oil companies in terms of capitalization. On July 27, 2006, the Board of Directors approved: |  | (i) the award pertaining to 2006 within the three-year period covered by the plan; (ii) its regulation; and (iii) the criteria to be followed in the identification of managers to whom the option will be assigned. The Board of Directors delegated to the CEO the task to identify eligible managers by the end of each year covered by the plan. Under this plan, 7,050,000 options were awarded pertaining to 2006 with a strike price of euro 23.119. Previous stock option plans provided that grantees had the right to purchase treasury shares in a 1 to 1 ratio after three years from the award, with a strike price calculated as the arithmetic average of official prices registered on the Mercato Telematico Azionario in the month preceding award or, if greater, as the average carrying cost of treasury shares held by Eni as of the date preceding the award. At December 31, 2006, a total of 15,290,400 options were outstanding for the purchase of an equal amount of ordinary shares nominal value euro 1 of Eni SpA, carrying an average strike price of euro 21.022. The weighted-average remaining contractual life of options outstanding at December 31, 2003, 2004, 2005 and 2006 was 4.6 years, 5.6 years, 6.6 years and 5.6 years, respectively.

Board Committees The Board has instituted three committees with proposal and advisory functions. Their composition, tasks and functioning are defined by the Board of Directors in respect of the criteria established by the Eni Code. They are: a) the Internal Control Committee, b) the Compensation Committee and c) the International Oil Committee, composed almost exclusively of independent Directors. In its meeting of June 1, 2005, the Board appointed the following directors as members of the Committees: Internal Control Committee: Marco Reboa (Chairman, independent), Alberto Clô (independent), Renzo Costi (independent), Marco Pinto (non-executive) and Pierluigi Scibetta (independent); Compensation Committee: Mario Resca (Chairman, independent), Renzo Costi (independent), Marco Pinto (non-executive) and Pierluigi Scibetta (independent); International Oil Committee: Alberto Clô (Chairman, independent), Paolo Scaroni (CEO), Dario Fruscio (independent) and Marco Reboa (independent). The Code, in line with the Borsa Italiana Code, suggests the creation of a “Nominating Committee”. The Board of Directors has not formed this Committee in consideration of the shareholding characteristics of Eni. Internal Control Committee The Internal Control Committee is entrusted with advisory and consulting tasks in respect of the Board in the area of monitoring general management issues. In the course of 2006, the Internal Control Committee met 15 times, with an average participation of 80% of its members, and reviewed the following: (i) the 2006 audit plan prepared by Eni, Saipem and Snam Rete Gas internal audit functions and their progress; (ii) findings and results from Eni’s internal auditing interventions; (iii) initiatives undertaken and effects of measures applied in order to eliminate the weaknesses highlighted by Eni’s Internal Audit department; (iv) the essential features of the 2005 financial statements, making suggestions intended to improve the level of disclosure throgh meetings with top level representatives of administrative functions of the main Eni subsidiaries, chairmen of boards of statutory auditors and responsible partners from external audit companies; (v) Eni’s 2006 draft Half Year Report; (vi) the “Recommendations on the internal accounting control system” presented on 2004 financial statements by the external audit company; (vii) the external audit |  | company reports on “Facts and circumstances of interest in the governance activity”; (viii) the situation of appointments of external auditors of main group companies, the recognition of costs incurred and the observations contained in the reports of external auditors pertaining to the financial statements of Eni’s subsidiaries; (ix) the proposal to integrate the task of Eni’s external auditors, to also include the certification of Eni’s internal control system, under Section 404 of the Sarbanes-Oxley Act (SOA) for fiscal year 2006, and the proposal extending the task of the external auditor currently in charge to audit the financial statements of Group companies and to certify the Group internal control system over financial reporting as well as all other admissible tasks for the 2007-2009 period; (x) the report on the implementation of SOA activities; (xi) the report presented by the Watch Structure established as required by Legislative Decree No. 231/2001; (xii) the general aspects of rules on recommendations received by Eni, which also include confidential or anonymous recommendations, issued also in respect of the Sarbanes-Oxley Act, and the periodic reports concerning the received recommendations; (xiii) the new organizational structure and the tasks of Eni Internal Audit function; (xiv) the reorganization of the Group supply activities; (xv) issues on hydrocarbon reserves and relevant classification criteria, also including accounting issues; (xvi) appointments of consultants and legal counsellors supporting the Company on legal matters for the 2005-2006 two year period; (xvii) antitrust procedures and the recognition of the relevant provisions to the risk reserve; (xviii) the reports on additional information submitted to the SEC and accounting treatment of the merger of Enifin with the parent company Eni; (xix) the report on Eni administrative and accounting organization to be submitted to the Board of Directors. The Internal Audit Manager is the secretary of the Committee. In its meeting of March 16, 2007, the Board of Directors, as proposed by the CEO, in agreement with the Chairman and after asking the Internal Control Committee for its opinion, entrusted the Internal Audit Manager as manager delegated for the internal control.

In 2006, the Committee appointed external consultants to acquire analysis and advice on its specific matters. |  | International Oil Committee The International Oil Committee is entrusted with the monitoring of trends in oil markets and the study of their aspects. In 2006 the International Oil Committee met five times with a 75% participation of its members. The first meeting concerned trends and conditions of the oil and gas industry, as well as the key variables of the energy scenarios for Eni’s four-year strategic plan. The other meetings concerned the analysis of worldwide energy market prospects to 2020, to identify the main issues and challenges to be addressed in Eni Master Plan – a key document in the planning process defining Eni industrial strategies. In particular, the meetings dealt with: (i) worldwide energy consumption trends to 2020 – discussed in two meetings – aimed at identifying fundamentals, underlying assumptions and possible uncertainties in consumption trends in the most important world areas; (ii) a survey of the supply of natural gas in the world and (iii) a survey of the worldwide oil supply, highlighting hydrocarbons and infrastructure development trends, in relation to the industrial and market trends in the next 15 years. Board of Statutory Auditors and other control entities Board of Statutory Auditors The Board of Statutory Auditors, in accordance with Legislative Decree No. 58/1998 (TUF), monitors: (i) the respect of laws and of Eni’s memorandum of association; (ii) the respect of the principles of proper administration; (iii) the adequacy of the company’s organizational structure, for the parts covered by the Board's responsibility, of its internal control system and administration and accounting systems as well as the reliability of the latter in fairly representing the management of the company; (iv) the adequacy of instructions conveyed by the parent company to its subsidiaries according to Article 114, paragraph 2 of the above mentioned decree; (v) the actual implementation of corporate governance rules foreseen by the codes of conduct prepared by market regulators and the associations the company belongs to, that the company publicly declares to respect.

control provided to Eni by the auditing firm and the entities belonging to its network. According to the TUF (as amended by Legislative Decree No. 303/2006), the Board of Statutory Auditors drafts a proposal regarding the appointment of the external auditors and their fee to be submitted to the Shareholders’ Meeting for approval. The Board of Directors, in its meeting of March 22, 2005, in accordance with the provision of the SEC Rule 10A-3 for non-US companies listed on US stock exchanges, elected the Board of Statutory Auditors to fulfill the role of the audit committee in US companies under the Sarbanes-Oxley Act and SEC rules, within the limits set by Italian legislation from June 1, 2005. On June 15, 2005, the Board of Statutory Auditors approved the regulation for carrying out the functions attributed to the audit committee under US laws. This regulation is published on Eni’s website. Composition and appointment The Board of Statutory Auditors is comprised of five auditors and two alternate auditors, appointed by the Shareholders’ Meeting for a three-year term. On May 27, 2005, Eni’s Shareholders’ Meeting appointed the following statutory auditors for a three-year period and however until the Shareholders’ Meeting approving financial statements for fiscal year 2007: Paolo Andrea Colombo (Chairman), Filippo Duodo, Edoardo Grisolia, Riccardo Perotta and Giorgio Silva. Francesco Bilotti and Massimo Gentile are alternate auditors. A curriculum of these auditors is published on Eni’s website. The same Meeting also determined the yearly compensation of the Chairman of the Board of Statutory Auditors and each Auditor amounting to euro 115,000 and euro 80,000 respectively. Paolo Andrea Colombo, Filippo Duodo, Edoardo Grisolia and Francesco Bilotti were candidates in the list presented by the Ministry of Economy and Finance; Riccardo Perotta, Giorgio Silva and Massimo Gentile were candidates in the list presented by institutional investors coordinated by Fineco Asset Management SpA. Statutory Auditors are appointed in accordance with Eni’s By-laws with a list vote; at least two auditors and one substitute are chosen from minority candidates. According to Article 28.2 of Eni’s By-laws, as revised by the Shareholders’ Meeting of May 25, 2006, to implement the provision of Law No. 262 of December 28, 2005 (law on the protection of savings), the Shareholders’ Meeting elects Chairman of the Board of Statutory Auditors a member elected from a list other than the one obtaining the majority of votes; this prescription will be applied in the next Board election. The lists of candidates include declarations made by |  | the candidates on the possession of independence and expertise requirements prescribed by applicable regulation and a professional resume of each candidate, must be filed at the company’s headquarters at least 10 days before the date of the Shareholders’ Meeting on first call and are published in national newspapers. Expertise and independence In accordance with the TUF, Statutory Auditors have to possess the specific requirements of independence, and the professional and honorability requirements as prescribed by a regulation of the Minister of Justice. As also reported in the Code, the Statutory Auditors shall act with autonomy and independence also vis-à-vis the shareholders who elected them. As for professional qualifications of the candidates, Article 28 of Eni’s By-laws, in line with the said Decree of the Minister of Justice, foresees that the professional requirements can also be acquired with at least three years of professional experience or by teaching business law, business administration and finance, as well as at least a three year experience in a managerial position in geological or engineering businesses. Eni’s auditors are all chartered auditors. Article 28 of Eni’s By-laws also prohibits the appointment as statutory auditor of persons that are statutory auditors or members of the supervisory board or members of the management control committee of at least five companies with registered securities in regulated markets not subsidiaries of Eni SpA. In case such persons are elected, their task is terminated. This prescription should be replaced by a Consob regulation defining the maximum allowed number of appointments of a statutory auditor in line with the TUF. In its meeting of March 16, 2007, the Board of Statutory Auditors verified that all its members complied with the independence criteria prescribed by the rules of the Eni Code intended to ensure the Statutory Auditors’ possession of required independence after their appointment, also based on the criteria defined by the Code for the members of the Board of Directors. Meetings and functioning Statutory auditors receive information on all issues on the agenda of the Board of Directors at the same time as the Directors. In line with the provisions of the Eni Code, an Auditor who has an interest, either own or on behalf of third parties, in a certain transaction of the issuer, shall inform the Board of Directors and the other Auditors. In 2006, the Board met 20 times with an average participation of 88% of its members.

Further Auditors' appointments Based on information received, information on positions held by the members of Eni’s Board of Statutory Auditors in other Boards of Directors and Boards of Statutory Auditors of listed companies, also abroad, financial, banking, insurance or large companies is provided below. The curriculum of each Auditor is available on Eni’s website. PAOLO ANDREA COLOMBO Chairman of Sintesi SpA, independent Director of Mediaset SpA, Interbanca SpA, Iniziative Gestione Investimenti SpA, RCS Quotidiani SpA, SIAS SpA, Director of Versace SpA. Chairman of the Board of Statutory Auditors of Ansaldo STS and Saipem SpA. Auditor of Aviva SpA, Lottomatica SpA and Sirti SpA.

RICCARDO PEROTTA Chairman of the Board of Statutory Auditors of Snam Rete Gas SpA and Gewiss SpA, Auditor of ECS International Italia SpA. GIORGIO SILVA Auditor of Luxottica SpA and RCS Mediagroup SpA. External Auditors As provided for by Italian law, the auditing of financial statements is entrusted to external auditors registered on the register held by Consob. The external auditor is appointed by the Shareholders’ Meeting. Eni’s external auditor, PricewaterhouseCoopers SpA, was appointed by the Shareholders’ Meeting of May 28, 2004 for a three-year term ending with the Meeting approving financial statements for 2006. Financial statements of Eni subsidiaries are audited, mainly by PricewaterhouseCoopers. In order to express its opinion on Eni’s consolidated financial statements PricewaterhouseCoopers took the responsibility of the audit activities performed by other auditors on certain Eni fully consolidated subsidiaries representing, however, a negligible part of Eni’s consolidated assets and revenues. Eni’s external auditor and the companies belonging to its network are not to be entrusted with tasks not pertaining to audit activities, except for rare and |  | motivated cases for tasks – not prohibited by Consob and the Sarbanes-Oxley Act – subject to authorization by Eni’s Board of Statutory Auditors and to approval by the Board of Directors of Eni Group companies upon favorable opinion of their Board of Statutory Auditors. Eni’s Board of Statutory Auditors must be informed of all tasks entrusted to external auditors by Eni Group companies. Other auditing The accounts of the parent company Eni SpA are subject also to the review of the Italian Court of Accounts. The relevant activity is performed by the Magistrate delegated to control, Lucio Todaro Marescotti (alternate Magistrate Angelo Antonio Parente), replacing Luigi Schiavello, as decided on July 19-20, 2006, by the Governing Council of the Italian Court of Accounts. The Magistrate delegated to control attends the meetings of the Board of Directors, the Board of Statutory Auditors and the Internal Control Committee. Internal controls Eni is aware that financial information plays a crucial role in the creation and maintenance of satisfying relationships between the company and its increasingly wide area of stakeholders, and contributes, as well as the group performance, to the creation of value for the shareholders. Eni is also aware that investors rely on Eni managers and employees respecting procedures and rules of the company’s internal control system. In this area a special relevance is attribuited to Eni’s Code of Conduct that identifies the fundamental values for the deployment of Eni activities in the formal and substantial legitimacy of behavior of its employees at any organizational level, the transparency of accounts and disclosure, and the spreading of a control oriented attitude. The Board of Directors evaluates the consistency of the internal control system with the company structure and characteristics. The CEO monitors the functionality of the internal control system, supported by the manager in charge of the internal control and by the Internal Audit department. In particular, the Board of Directors is assisted by the Internal Control Committee in the performance of the tasks related to: (i) defining the guidelines for the company’s internal control system intended to ensure that the main company risks are correctly identified, measured, managed and monitored, also determining whether such risks are compatible with a sound and a correct management of the company; (ii) annually evaluating the suitability, effectiveness and

100

ENI ANNUAL REPORT / CORPORATE GOVERNANCE

efficient operation of the internal control system; (iii) disclosing the key elements of the internal control system, and evaluating its overall adequacy in the annual report on corporate governance. In performing those tasks, the Board of Directors refers to available conceptual models and domestic and international best practices. Special attention is paid to organization and management models adopted according to Legislative Decree No. 231/2001 and to the Code of Conduct. In line with these principles, Eni adopted regulations for the preparation of financial statements of the Group companies and the collection of information necessary for timely and fair disclosure in quarterly and yearly reports in accordance with generally accepted rules and accounting standards, ensuring also uniformity of behavior, an essential element for the provision of proper financial information on the Group. With the aim of ensuring the effective and correct enactment of such rules, principles and standards and of general rules governing processes for information to be recorded, processed, summarized and reported, Eni adopted an internal control system designed with the aim of providing investors and markets with fair, complete and timely information. Eni internal control system has been designed in accordance with the provisions of the Sarbanes-Oxley Act of 2002 (SOA) which Eni has to comply with as its securities are listed on the New York Stock Exchange. Such control system was designed in accordance with two fundamental principles: to extend control to all the levels of the organizational structure, consistently with the operating task entrusted to each level; sustainability of controls in the long term, so as to ensure that the performance of controls is increasingly integrated in and compatible with operating needs; for this purpose, specific controls have been selected in order to identify such critical controls as to mitigate the level of risk. The objectives of the internal control system have been defined consistently with applicable provisions of US rules distinguishing two systemic components: disclosure controls and procedures; internal control over financial reporting. Disclosure controls and procedures are defined as controls and other procedures of the company that are designed to ensure that information required to be disclosed by the company in its reports is collected and communicated to Eni management, including Eni’s CEO and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. |  | Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Eni’s internal control over financial reporting has been designed to be consistent with the Internal Control-Integrated Framework created and published by the Committee of Sponsoring Organizations of the Treadway Commission and comprises five interrelated components: control environment, risk assessment, control activities, information and communication, and monitoring. Such components in relation to their own features operate at entity level (Group, business segment, divisions, subsidiary) and/or at a process level, including both operational and financial administration process (transaction, evaluation processes and closing the books). The key objective of internal control over financial reporting is to mitigate risks due to negligence and risks of fraud, significantly impacting financial statements. In addition, a specific risk assessment has been performed on fraud risks, and from this anti-fraud measures and controls have been designed. Management has developed its own assessment procedures to evaluate the design of Eni’s internal control over financial reporting and its operating effectiveness. To that end, management has implemented ongoing monitoring activities entrusted to managers who are responsible of conducting primary processes or activities, and separate evaluations have been entrusted to Eni’s Internal Audit department. This department operates according to a preset plan of interventions defining scope and objectives of each intervention. Outcomes from all monitoring activities are reported periodically in order to ascertain the state of Eni’s internal control over financial reporting. All levels of Eni’s organizational structure are involved in this reporting process. A primary role in Eni’s internal control over financial reporting is played by the Internal Audit department, directly reporting to the CEO and to the Board of Statutory Auditors in its quality of audit committee under the SOA. The Internal Audit Manager, in his/her role as responsible for internal control activities, reports to the CEO, to Eni’s Internal Control Committee and to the Board of Statutory Auditors. Among the tasks entrusted to the Internal Audit department are: (i) to ensure implementation of the following activities: vigilance activity as required by Legislative Decree No. 231/2001; separate evaluations as required by the SOA,

101

ENI ANNUAL REPORT / CORPORATE GOVERNANCE

operational, financial, information technology and fraud auditing activities on behalf of Eni divisions and Eni’s fully-owned subsidiaries lacking their own Internal Audit departments; (ii) to update Eni’s system for identifying, classifying and assessing risk areas in order to plan control activities; (iii) to implement planned and non-planned control activities, and to identify possible gaps with respect to adopted conceptual models, also making proposals on corrective measures and monitoring subsequent follow-up activities; (iv) to maintain relationships with external auditors; (v) to maintain relationships with and ensure information flows to the Watch Structure, the Internal Control Committee and the Board of Statutory Auditors; (vi) to ensure the management of the recommendations received by Eni, also under an anonymous form, during the internal preliminary investigations and supporting the entrusted company bodies in their evaluation process, always in full compliance with Eni procedures. The integrated auditing plan and the outcomes of the activities performed are evaluated by the Internal Control Committee, the Board of Statutory Auditors, and the Watch Structure within the boundaries of the matters covered by Legislative Decree No. 231/2001. The Internal Audit department and the external auditors have complete access to data, information and documentation which can support the performance of auditing activities. Legislative Decree No. 231/2001 In its meetings of December 15, 2003 and January 28, 2004 the Board of Directors approved a “Model for organization, management and control according to Legislative Decree No. 231/2001” and established a Watch Structure. Legislative Decree No. 231/2001 states the administrative responsibility of entities such as companies and partnerships, according to Article 11 of Law No. 300 of September 29, 2000. The principles of the “231 model” are published on Eni’s website. The criteria for the preparation of this model are those included in a guidebook prepared by Confindustria (the Italian association of industrial companies) as verified by the Ministry of Justice as required by the same Decree. The model was transmitted to all Group companies for application. Transactions in which a director has an interest and transactions with related parties In accordance with the TUF and with Article 23.3 of Eni’s By-laws, the Directors shall timely inform the Board of Statutory Auditors on transactions in which they have an interest. |  | During each Board of Directors’ meeting, the Chairman expressly asks the Directors to declare any of their potential interest in transactions on the agenda. The Eni Code, in accordance with the Borsa Italiana Code, foresees the adoption, by the Board of Directors, of measures ensuring that transactions in which a director has an interest, directly or on behalf of third parties, and all transactions carried out with related parties, are performed in a transparent way and meet criteria of substantial and procedural fairness. In addition, the Eni Code foresees a specific opinion of the Internal Control Committee on the rules adopted by the Board of Directors. Preparation of a procedure regarding transactions with related parties is underway; however its finalization is stalling due to the circumstance that Italian listed companies are awaiting the emission on part of Consob of certain guidelines that Article 2391-bis of the Civil Code assigns to Consob. Pending the emission of such guidelines, Eni’s internal rules provide that transactions with related parties be submitted to the Board of Directors, even though of amounts lower than the materiality threshold set for the transactions to be approved by the Board; The Board of Directors’ resolution defining the powers of the Board itself points out the needs to pay particular attention to those situations in which a director has an interest and to transactions with related parties. Moreover, Eni is committed to observing principles as defined in the Borsa Italiana Code regarding such persons holding significant positions in the share capital of listed companies and in particular respecting their managerial autonomy. In the ordinary course of its business, Eni enters into transactions concerning the exchange of goods, provision of services and financing with related parties as defined by IAS 24. These include non consolidated subsidiaries and affiliates as well other companies owned or controlled by the Italian Government. All such transactions are conducted on an arm’s length basis and in the interest of Eni Group companies. Eni’s Directors, General Managers and managers with strategic responsibilities disclose every six months any transactions with Eni SpA and its subsidiaries that require disclosure under IAS 24. Amounts and types of trade and financial transactions with related parties and their impact on consolidated earnings and cash flow, and on the Group’s assets and financial condition are reported in Note 33 to the consolidated financial statements.

ENI ANNUAL REPORT / CORPORATE GOVERNANCE

Significant differences in corporate governance practices as per Section 303A.11 of the New York Stock Exchange Listed Company Manual Corporate governance As discussed above, Eni’s organizational structure follows the traditional Italian model of companies which provides for two main separate corporate bodies, the Board of Directors and the Board of Statutory Auditors to whom management and monitoring duties are respectively entrusted. This model differs from the U.S. unitary model which provides for the Board of Directors as the sole corporate body responsible for management and for audit committee established within the same Board for monitoring. Below is a description of the most significant differences between corporate governance practices followed by U.S. domestic companies under the NYSE standards and those followed by Eni. INDEPENDENT DIRECTORS NYSE Standards Under NYSE standards listed U.S. companies’ Boards must have a majority of independent directors. A director qualifies as independent when the Board affirmatively determines that such director does not have a material relationship with the listed company (and its subsidiaries), either directly, or indirectly. In particular, a director may not deemed independent if he/she or an immediate family member has a certain specific relationship with the issuer, its auditors or companies that have material business relationships with the issuer (e.g., he/she is an employee of the issuer or a partner of the auditor). In addition, a director cannot be considered independent in the three-year “cooling-off” period following the termination of any relationship that compromised a director’s independence. Eni Standards In Italy, the Borsa Italiana Code recommends that the Board of Directors includes an adequate number of independent non-executive directors "in the sense that they do not maintain, nor have recently maintained, directly or indirectly, any business relationships with the issuer or persons linked to the issuer, of such a significance as to influence their autonomous judgement". The directors’ independence shall be periodically assessed by the Board of Directors. The results of the assessments of the Board shall be communicated to the market. The Board of Directors shall evaluate the independence of its non-executive members having regard more to the contents than to the form and keeping in mind that a director usually does not appear independent in the |  | following events, to be considered merely as an example and not limited to: a) if he/she controls, directly or indirectly, the issuer also through subsidiaries, trustees or through a third party, or is able to exercise over the issuer dominant influence, or participates in a shareholders’ agreement through which one or more persons may exercise a control or considerable influence over the issuer; b) if he/she is, or has been in the preceding three fiscal years, a relevant representative of the issuer, of a subsidiary having strategic relevance or of a company under common control with the issuer, or of a company or entity controlling the issuer or able to exercise over the same a considerable influence, also jointly with others through a shareholders’ agreement; c) if he/she has, or had in the preceding fiscal year, directly or indirectly (e.g., through subsidiaries or companies of which he/she is a significant representative, or in the capacity of partner of a professional firm or of a consulting company) a significant commercial, financial or professional relationship: - with the issuer, one of its subsidiaries, or any of its significant representatives; - with a subject who, jointly with others through a shareholders’ agreement, controls the issuer, or – in case of a company or an entity – with the relevant significant representatives; - or is, or has been in the preceding three fiscal years, an employee of the abovementioned subjects; d) if he/she receives, or has received in the preceding three fiscal years, from the issuer or a subsidiary or holding company of the issuer, a significant additional remuneration compared to the “fixed” remuneration of non-executive director of the issuer, including the participation in incentive plans linked to the company’s performance, including stock option plans; e) if he/she was a director of the issuer for more than nine years in the last 12 years; f) if he/she is vested with the office of executive director in another company in which an executive director of the issuer holds the office of director; g) if he/she is shareholder or quotaholder or director of a legal entity belonging to the same network as the company appointed for the accounting audit of the issuer; h) if he/she is a close relative of a person who is in any of the positions listed in the above paragraphs. The Eni Code foresees further independence requirements, in line with the ones provided by the

Borsa Italiana Code. In its meeting of February 22, 2007, Eni’s Board of Directors judged that six out of eight of its non-executive members comply with the independence standards, set by the Eni Code. Non-executive Director Marco Pinto is an employee of the Ministry of Economy and Finance. MEETINGS OF NON EXECUTIVE DIRECTORS NYSE Standards Non-executive directors, including those who are not independent, must meet at regularly scheduled executive sessions without management. In addition, if the group of non-executive directors includes directors who are not independent, independent directors should meet separately at least once a year. Eni Standards Neither Eni’s non-executive directors nor Eni’s independent directors must meet separately,under the Code’s corporate governance rules. AUDIT COMMITTEE NYSE Standards Listed U.S. companies must have an audit committee that satisfies the requirements of Rule 10A-3 under the Securities Exchange Act of 1934 and that complies with the further provisions of the Sarbanes-Oxley Act and of Section 303A.07 of the NYSE Listed Company Manual. Eni Standards In its meeting of March 22, 2005, Eni’s Board of Directors, making use of the exemption provided by Rule 10A-3 for non-U.S. private issuers, has identified the Board of Statutory Auditors as the body that, starting from June 1, 2005, is performing the functions required by the SEC rules and the Sarbanes-Oxley Act to be performed by the audit committees of non-U.S. companies listed on the NYSE (see paragraph “Board of Statutory Auditors” earlier). Under Section 303A.07 of the NYSE listed Company Manual audit committees of U.S. companies have further functions and responsibilities which are not mandatory for non-U.S. private issuers and which therefore are not included in the list of functions shown in the paragraph referenced above. NOMINATING/CORPORATE GOVERNANCE COMMITTEE NYSE standards U.S. listed companies must have a nominating/corporate governance committee (or equivalent body) composed entirely of independent directors that are entrusted, among others, with the responsibility to identify individuals qualified to become board members and to select or recommend director nominees for submission to the Shareholders’ Meeting, as well as to develop and recommend to the Board of Directors a set of corporate governance guidelines. |  | Eni Standards This provision is not applicable to non-U.S. private issuers. The Code allows listed companies to have within the Board of Directors a committee for directors’ nominees proposals, above all when the Board of Directors detects difficulties in the shareholders’ submission of nominees proposals, as could happen in publicly owned companies. Eni has not set up a nominating committee, considering the nature of its shareholding as well as the circumstance that, under Eni’s By-laws, directors are appointed by the Shareholders’ Meeting based on lists presented by shareholders or by the Board of Directors. The shareholders The Shareholders’ Meeting During meetings, shareholders can request information on issues in the agenda. Information is provided within the limits of confidentiality, taking account of applicable rules regulating the matter of price sensitive information. With the aim of facilitating the attendance of shareholders, calls for meetings are published in Italian and foreign newspapers, Eni’s By-laws allow vote by correspondence and the collection of powers of attorney in Articles 13 and 14. On December 4, 1998, Eni approved a regulation for its meetings, available on Eni’s website, in order to guarantee an efficient deployment of meetings, in particular the right of each shareholder to express his opinion on the items in the agenda. The Shareholders’ Meeting held on May 25, 2006, in order to align Eni’s By-laws to the prescriptions of the TUF regulating the protection of investors, modified the By-laws stating that all the shareholders representing also with others, at least 1/40 of the share capital, can ask to add items to the agenda, within five days of the publication of the convening notice. Eni’s shareholders Eni SpA’s share capital at December 31, 2006, amounted to euro 4,005,358,876 fully paid and was represented by 4,005,358,876 ordinary shares, at a nominal value euro 1 each. Shares are not divisible and give right to one vote. Shareholders can exercise the rights provided by the law. In accordance with Article 6 of Eni’s By-laws, no shareholder, excepted the Italian Government, can directly or indirectly own more than 3% of Eni SpA’s share capital; the shares held above this limit do not allow to exercise the rights exceeding the 3% threshold. In 1995 Eni issued a sponsored ADR (American Depositary Receipts) program directed to U.S.

ENI ANNUAL REPORT / CORPORATE GOVERNANCE

Special powers of the State - golden share Under Article 6.1 of Eni’s By-laws only the Italian State can hold shares representing more than 3% of Eni’s share capital. Eni’s By-laws in Article 6.2 attribute to the Minister for Economy and Finance, in agreement with the Minister of Economic Development, the following special powers to be used in compliance with the criteria indicated in the Decree of the President of the Council of Ministers of June 10, 2004: (a) opposition with respect to the acquisition of material shareholdings representing 3% of the share capital of Eni SpA having the right to vote at ordinary Shareholders’ Meetings. Such opposition is required to be expressed within 10 days of the date of the notice to be filed by the Board of Directors at the time a request is made for registration in the Shareholder’ register, should the transaction be considered prejudicial to vital interests of the State; (b) opposition with respect to the subscription of shareholders’ agreements or other arrangements (as defined by Article 122 of Legislative Decree No. 58 of February 24, 1998) whereby 3% or more of the share capital of Eni SpA having the right to vote at ordinary Shareholders’ Meetings is involved; (c) veto power – duly motivated by the case of prejudice to the interests of the State – with respect to shareholders’ resolutions to dissolve Eni SpA, to transfer the business, to merger or to demerger, to transfer the registered office of Eni SpA outside Italy, to change the corporate purposes or to amend or modify any of the special powers described in this section; (d) appointment of a Board member without voting right.

The introduction of these norms in Eni’s By-laws, subject to approval by the EU, will entail the cancellation of the 3% threshold to individual shareholdings, except for the State, as contained in Article 6.2 of Eni’s By-laws. Eni’s By-laws modifications Legislative Decree No. 303/2006 introduced changes to the law on protection of savings.

ENI ANNUAL REPORT / COMMITMENT TO SUSTAINABLE DEVELOPMENT

Commitment to sustainable development
INTRODUCTION

In keeping with its tradition and leveraging on its track record with the values it consolidated in the course of time and on the skills and passion of the persons working for it, Eni confirmed and renewed its commitment to sustainable development which touches upon various aspects of its activities: from the enhancement of persons to the respect for the environment, to the development of local communities, to technological innovation. These are priorities for all companies, but the more so for a large international company operating in a business where a good management of resources and social and environmental issues is one of the keys for success. Eni is committed to promoting the sustainability of its results in time and to widening its relations with its stakeholders, improving corporate performance and increasing the value of intangible assets. Eni’s business model will therefore be adjusted in order to guarantee that the goal of sustainability becomes an integral part of its management and development processes. Assigning value to its experience, in 2006, Eni introduced the issue of sustainability as a tool for management and integrated communication. It therefore started a specific project that was carried out by various organizational units and determined the creation of a unit specifically dedicated to sustainability. In its meeting of February 22, 2007 Eni’s Board of Directors discussed and approved the strategic guidelines of its 2007-2010 Strategic Plan where it identified the main challenges and commitments in the area of sustainability in the next years. For the first time this year, Eni’s reporting system includes a Sustainability Report, which will be published along with this Annual Report and is available in the “Sustainability” and “Investor Relations” sections of Eni’s website (www.eni.it). |  | Since 2001, in the field of human rights, Eni has been supporting the United Nations’ initiative Global Compact which aims at promoting policies and practices oriented to sustainability by means of the sharing and application of ten basic principles in the fields of human rights, workplace standards, protection of the environment, fight against corruption. Challenges and commitments As concerns the various areas impacted by sustainability, Eni identified the main challenges that oil & gas companies will have to face in future years and defined its commitment to the attainment of sustainable development. Governance and stakeholder engagement To the greater attention paid to the transparency and sustainability of its governance model and processes Eni responded by committing itself to: set up and strengthen a governance system that corresponds to international best practices, capable of managing complex situations in numerous countries in the world and the challenges of sustainable development; adopt systematic stakeholder engagement forms, extending dialogue on the issues of sustainability and corporate responsibility with relevant stakeholders. Persons To the competition in hiring and maintaining qualified professionals and to the need to favor the development of local personnel, at the same time protecting their health and guaranteeing high security standards Eni

responded by committing itself to: attract the best domestic and international resources; manage human resources internationally with homogenous tools, promoting diversity; promote health and safety of employees, contractors and local communities; enhance the potential and professional capability of its human resources. Environmental responsibility To the challenge of meeting the increasing demand for energy while at the same time mitigating emissions and the impact on ecosystems Eni responded by committing itself to: develop preferentially fossil sources with low carbon intensity, in particular natural gas; participate actively in emission trading systems and in projects aimed at reducing emissions based on the flexible mechanisms suggested by the Kyoto Protocol; mitigate the local environmental impact of its activities by improving environmental performance and recovering and reusing resources; reduce its ecological footprint also by means of remediation and reclaiming activities; preserve biodiversity also by means of improved monitoring techniques of onshore and offshore ecosystems. Innovation To the strategic importance of innovation for a sustainable use of energy sources Eni responded by committing itself to: develop technologies that increase the availability of hydrocarbons, maximizing the use of existing reserves and protecting safety and the environment in the exploration of new resources; reduce its contribution to climate change by investing in innovation capable of generating discontinuity such as emerging solar technologies; anticipate regulations on fuel quality, the evolution of engines and of market demands, by entering the field of marketing and extending the use of biofuels with high performance and low environmental impact. Territory and communities To the need for involvement of local stakeholders and the support of development of local communities Eni responded by committing itself to: promote stakeholder consultation also at the level of local communities, on industrial projects aimed at enhancing the value of local socio-economic systems of the countries and local communities where it operates; |  | cooperate with governments and local authorities and with international non-governmental organizations on crucial issues; promote actions for supporting the ability for autonomous development of local communities. Stakeholder engagement Eni is aware that the creation of value and its sustainability in time depend on the quality of its relations with its stakeholders. Eni’s strategy includes a serious commitment to the promotion of an open and fruitful dialogue with all the organizations legitimately interested in Eni’s activity as well as a commitment to respect these organizations’ requirements. This approach is crucial for a large international company that operates in complex environments, where the proper management of stakeholders’ legitimate interests and expectations is a key factor for success. Eni has adopted a stakeholder engagement methodology (identification, analysis and consultation) which provides its business units with all the elements required to receive feedback from stakeholders thus increasing the level of consensus on projects. In 2006, Eni also prepared a reference and support methodology for the evaluation and management of the social impacts it produces in the areas where it operates by means of a Guide to Social Impact Assessment (SIA). This guide, prepared on the basis of the most advanced international guidelines contains: references to Eni principles and values; a description of the most relevant socio-economic issues; methods for impact evaluation; operating tools for impact management within projects; a detailed bibliography. During its preparation the guide has been tested as working document at some operating sites (Kashagan, Karachagansk, Australia, Norway). More detailed information on the management of stakeholder engagement is found on Eni’s website in the area Sustainability and in the Report on Sustainability.

HUMAN RESOURCES AND ORGANIZATION

To Eni the persons working in its production system represent a wealth to be safeguarded and enhanced with careful career paths. This path, made up of accurate development and training initiatives customized to roles and persons, along with the respect of shared ethical values, represents a key factor for the creation of sustainable value in the long term. Eni’s main objectives for its human resources are: to guarantee safety and health of all employees and contractors; to plan initiatives for the management and development of human resources, orienting personal development and growth consistently with the evolution of business; to attract the best resources at domestic and international level through intense links with universities and research centers and actively contributing to the training of young generations; to develop and share know-how through the systematization and dissemination of knowledge and the best international corporate practices; to manage human resources internationally with homogenous tools respecting local regulations and cultures; to obtain excellent results in industrial relations at domestic and |  | international level; to achieve maximum efficacy in internal communication, engagement and training. More detailed information on the management of human resources is found on Eni’s website in the area Sustainability and in the Report on Sustainability. Employees and labour costs At December 31, 2006, Eni’s employees totaled 73,572, with an increase of 1,314 employees from December 31, 2005, or 1.8%, reflecting a 1,741 increase in employees hired and working outside Italy and a decline of 427 employees hired in Italy.

of 1,486 persons were hired with this type of contract and with apprenticeship contracts, most of them with university qualifications (824 persons of which 532 are engineers) and 632 persons with a high school diploma. During the year 2,599 persons left their job at Eni, of these 1,960 had an open-end contract and 639 a fixed-term contract. Employees hired and working outside Italy at December 31, 2005 were 33,807 (46% of all Group employees), with a 1,741 persons increase due to the positive balance of new hires with fixed-term contracts and persons leaving their job in Saipem and Snamprogetti (1,853 employees) and the negative balance (112 persons) of persons leaving the job and new hires with open-end contracts in the rest of the Group. Labor costs increased from euro 3,351 million in 2005 to euro 3,646 million in 2006, a euro 295 million increase, or 8.8%, reflecting primarily redundancy incentives, ordinary payroll dynamics and an increase in average workforce outside Italy in particular in the Engineering & Construction segment, offset in part by a decrease in average workforce in Italy. Organization Eni introduced significant actions for the upgrading of structures and processes to the new integrated corporate model adopted which includes: a full assumption of responsibility of businesses and their integration on wide reaching actions, the strengthening of Eni Corporate’s role of orientation and coordination, the sharing of business services with the aim of greater efficiency of services provided, the integrated control and governance of performance by means of heads of professional units, a widespread simplification of the |  | organizational set-up of companies, full compliance of control processes and systems with laws and regulations. Management and development of human resources Eni started and completed various initiatives aimed at making the evaluation and development of human resources more efficient. In particular, Eni completed a plan of rejuvenation of management which determined a significant decrease in average age at all levels of management and enhanced the tools for the evaluation of the development potential of resources, coupling the appraisals made at (hierarchical and functional) line level with those performed by external experts. These activities were addressed to key managers, developing young managers and newly recruited graduates. Eni performed an updating of policies directed to employees outside Italy and introduced compensation schemes adequate with the dynamics of international resource markets. The whole body of internal regulations and methodologies for planning, managing and developing human resources is currently under review, also in light of the increasing importance of sustainability. With nearly 46% of its employees of non-Italian nationality, Eni has always considered diversity as an element that generates value and the ability in managing it as a key factor for success. In the countries where it operates, Eni promotes the development of skills of local human resources and the construction of a shared culture by means of training initiatives oriented to the understanding of intercultural diversity, intercultural communication and multicultural teamwork, initiatives that have been performed also within the European Works Council with the active participation of workers’ unions. Training Eni considers training one of the strong points of the management of human resources. The number of hours dedicated to training and the number of employees participating in training initiatives are evidence of Eni’s significant commitment in Italy and outside Italy. In 2006, expenditure for training amounted to euro 22.6 million (up about 2% from 2005). In 2006, a total of 1,167,633 training hours (1% lower than in 2005) were provided in Italy to a total of 23,941 employees (232 senior managers, 6,822 middle managers and senior staff, 12,180 employees and 6,192 workers) for a total of 90,319 participations.

In 2006, expenditure for training outside Italy amounted to euro 34.6 million. A total of 1,131,530 training hours (2% higher than in 2005) were provided to a total of 8,091 employees (208 senior managers, 2,604 middle managers and senior staff, 3,585 employees and 1,694 workers) for a total of 28,487 participations. Eni Corporate University, in its role of group company covering the fields of personnel selection, training and knowledge management aimed at matching the quality of Eni’s human resources with the company’s strategies, covering the whole “knowledge cycle” from the planning of requirements to the construction of integrated academic curricula in cooperation with universities in Italy, up to the selection of new talents and their training during their professional lives. In 2006, ECU prepared a thorough survey of the issue of knowledge management in Eni’s business units and prepared a “Plan for the development of Eni’s knowledge system 2007-2008”. In early 2007, Eni celebrated the 50th anniversary of the establishment of the Scuola Mattei operating in research and post-graduate training. The integration of energy and the environment and an international faculty and students are the key features of the school. From its foundation in 1957, the school trained nearly 2,500 young talents, of these 55% came from nearly 100 countries of the world. It recently created three new curricula directed to about 100 students from Italy and the rest of the world. Industrial relations Industrial relations within a consolidated and structured system represented an efficient and consistent support to Eni’s strategic choices and to the completion of reorganization processes underway. With Italian workers’ unions, Eni defined the renewal of collective contracts (for the segments of energy and oil and chemicals) expired in late 2005. As for the collective contract for the gas-water segment, also expired at the end of 2005, negotiations between workers’ unions and companies’ organizations are underway. Internationally, Eni continued its dialogue with workers’ unions in specific forums such as the European Works Council. Eni’s Multicultural Training Project, which takes place every year in a different country with the cooperation of members of the EWC, held training courses in France addressed to 300 employees of Saipem SA. This course was awarded the first prize Etica&Impresa at the end of 2006. |  | Health Activities for the protection of health aim at improving general work conditions and are developed according to three main principles: protection of employees’ health; prevention of accidents and professional diseases; promotion of healthier behaviors and life styles in workplaces. Eni has a network of 307 own health care centers located in its main operating areas of these 217 centers are outside Italy and are managed by expatriate and local staff (415 doctors and 442 paramedics). A set of international agreements with the best local and international health centers guarantees efficient service and timely reactions to emergencies. In 2006, Eni boosted its E-medicine program aimed at increasing the quality of health care provided to employees and to health operators within and outside Italy, that integrates computerized technologies and advanced telecommunication systems. Eni started a program of prevention for its employees, both through information campaigns and by means of screening procedures and direct actions accessed on a voluntary basis. In the area of prevention of infective diseases, Eni continued its campaign for vaccination against flu that is widely followed by employees. Outside Italy, Eni promoted specific information campaigns for the protection of its employees, their families and local communities, such as those for the prevention of malaria (in Nigeria) and the prevention of HIV transmission (in Nigeria and Congo). For employees hired in Italy and working outside Italy, Eni has a specific program that includes training on the specific health risks they might encounter in each country and information on how to cope with them. Eni also entered an agreement with International SOS that provides qualified health services throughout the world, as well as repatriation in case of serious emergency situations. Safety Eni has always been deeply engaged in the issue of the safety of its workers, of the people living in the areas where its industrial sites are located and of its producing assets. Its strategy has been based on: the dissemination of a safety culture within its organization; a common policy, specific guidelines for proper management systems meeting international standards;

control, prevention and protection from exposure to dangerous situations; minimization of exposure to risk in all production activities. Eni’s Guide on the evaluation and mitigation of risks published in 2004 by the HSE department describes the methods applied in the identification of dangers, evaluation and mitigation of risks associated to plants, processes, transportation means, workplaces, chemical substances and products used, produced and marketed. This process includes the following phases: identification of all exposures and risks related to processes, products and operations performed; evaluation of risks in terms of seriousness and frequency of accidents; |  | investigation and analysis of accidents in order to learn from them and increase the ability to prevent and mitigate risks; development of action plans for the minimization of risks focused mainly on capital expenditure, implementation of safety management systems and training of staff; monitoring and appraisal based on the identification, evaluation, correction of individual and process performance. In 2006, safety indicators improved from 2005. The injury frequency rate was 3.07, down 3%, and the injury severity rate was 0.09, down 10% from 2005.

RESPONSIBILITY TOWARDS THE ENVIRONMENT

Reference scenario The attention currently paid to the relevant issues of environmental sustainability and the corresponding regulatory developments at international level stimulate companies to engage beyond the simple compliance both as concerns locally and globally critical situations. The precautionary principle that informs current regulations requires that the actions taken by industrial companies to reduce their environmental footprint privilege the preventive approach to the remediation of damage done. In addition, the current operating context is characterized by increasing avoidance of risks thus posing stricter constraints to the “freedom of operations”, due to the progressive internalization of environmental externalities and also for the growing participation of local stakeholders to decision making processes. Companies are therefore required to |  | be more transparent on their environmental performance, as they are subject to careful scrutiny by stakeholders. In all its activities, Eni is actively committed to reducing its environmental footprint, decreasing its energy and water consumption, reducing local pollution of air, water and soils as well as waste production and to reclaiming discontinued industrial sites. Special attention is paid to the protection of biodiversity. More detailed information on the reduction of the environmental footprint is found on Eni’s website in the area Sustainability and in the Report on Sustainability. Rational use of natural resources The management of natural resources is aimed at a rational and sustainable use of these resources and their protection in all Eni’s operations.

The application of the best available technologies for the control of emissions into the atmosphere is one of the pillars of the current environmental regulations (IPPC/AIA, Italian environmental Law No. 152/06) and finds a responsible partner in Eni that strives to reduce the impact of its production processes on the environment. In this light, Eni approved capital expenditure for the technological improvement of the treatment of waste fluids, combustion in gas turbines and devices for the reduction of effluents applicable in combined cycle plants for the production of electricity, the control and monitoring of emissions from plant components and transport of fuels. The implementation directives for the management of waters concern the reduction in pure water consumption by developing recycling opportunities and the minimization of water discharge that in many instances is obtained at levels higher than those required by applicable laws. Eni made capital expenditure aimed at the adoption of integrated production cycles with a limited and combined use of water, at the construction of water treatment plants with the most updated technologies and at the construction of monitoring systems capable of providing periodic control of the most significant parameters. The protection of soils and ground waters is a very relevant aspect for the environment. Great attention is paid to it at the organizational and economic level. For years, Eni has been carrying out numerous programs for the protection of soils and the reclamation of soils and ground waters. Eni’s business units are provided with an internal organization that takes care of management and technical aspects, making recourse to highly qualified external professionals to carry on their reclaiming activities. Eni is also active in the area of waste produced by its industrial units with the aim of reducing its generation |  | and improving its final destination by increasing recycling and recovery and reducing incineration and landfilling. Oil Spill Production, handling and transport of oil products can give rise to spills of variable size. In order to protect the areas where it operates, Eni defined responsibilities and operating modes aimed at reducing the negative impact of oil spills. Tools available include the recourse to external professionals and/or international organizations. In 2006, a total of 139 oil spills were registered for a total of 6,150 bbl of oil spilled. Biodiversity Eni considers biodiversity an integral element of sustainable development and is engaged in the impact evaluation of its exploration and production activities both onshore and offshore. This engagement takes the form of supporting conservation projects on land and in the sea and of organizing actions that raise attention for biodiversity. The most relevant current projects are addressed to: Val d’Agri, an ecologically sensitive area rich in animal and vegetable species as confirmed by EU protected sites found in the valley; Ecuador, a country provided with ecosystems with an inestimable value, such as tropical forests containing rare species at risk; the Mediterranean Sea, where a project is evaluating the ecosystemic impact of platforms; the Arctic Sea, where the ecosystem is considered extremely valuable and fragile due to the lack of antropization; Kazakhstan, where Eni is currently organizing a workshop on biodiversity focusing on the Caspian Sea, a natural reserve characterized by many rare species.

THE FUTURE OF ENERGY AND INNOVATION

The future of energy The global energy scenario is complex and worries are widespread regarding the future of energy. The debate on the constant increase in energy consumption and the dreaded exhaustion of oil reserves often masked the real criticalities of the current energy system (insufficient capital expenditure in the Nineties, crisis due to overproduction, bottlenecks and inadequacy of refining systems, waste and inefficiency in energy use in industrial countries). Despite these events, hydrocarbons will continue to dominate the energy scenario in the next decades and to represent the most important and strategic energy source. Eni, a company active in oil and gas, will continue to deploy its activities in order to meet energy requirements. At the current state of knowledge, Eni believes that the massive use of fossil fuels can contribute to climate change and is therefore actively engaged in favor of a responsible use of energy and the protection of the environment. Eni’s growth model is sustainable development, and in particular, Eni is committed to mitigating the effects of climate change due to greenhouse gas emissions. New partnership models and access to oil reserves Partnerships with producing countries, infrastructure and innovation will play a basic role in guaranteeing the security of supplies, which is the main criticality of the world energy system. In fact, at the current state of knowledge, total recoverable hydrocarbon reserves amount to approximately 5,000 billion barrels and will allow to meet energy requirements for over 100 years. International oil companies such as Eni, however, have |  | access to less than 20% of proved hydrocarbon reserves, which are mainly controlled by national oil companies. IOC’s resources available for capital expenditure are limited and represent new economic and technological challenges in particular in the new frontiers of conventional hydrocarbons (e.g., production from fields in ultra deep waters) and non conventional hydrocarbons (such as the extraction of hydrocarbons from tar sands and extra heavy oils). Eni is engaged in maintaining high rates of production growth while guaranteeing the sustainability of its business in the medium- to long-term through the integral replacement of reserves produced. Eni’s activities are oriented to the exploration of basins located in Africa, the Barents Sea, the Middle East and the Gulf of Mexico and to the development of fields with extended productive life in West Africa, North Africa and Kazakhstan. The evaluation of new expansion opportunities in the field of non conventional oils and the goal of increasing the reserve replacement ratio are pursued by increasing activities and capital expenditure in R&D and innovation and paying great attention to the impact of such projects on the environment and local communities. In this context, Eni is constantly engaged in improving its models of cooperation with producing countries in order to overcome the current criticalities of the global energy system. Eni’s strategy of cooperation with producing countries will be characterized by a dialogue with partners. Eni is ready to promote new strategic alliances with producing countries based on the joint development of integrated projects aimed at reaching

the targets of energy and economic development set by each country. This perspective translates into a renewed commitment to develop innovative and fair partnerships and cooperation modes. In this light, Eni and the Russian company Gazprom entered into a significant strategic agreement in 2006 that will provide Italy with a relevant share of its natural gas requirements until 2035. A description of the main features of this agreement and its impact on Italy’s energy requirement is found in the Operating Review - Gas & Power and on Eni’s website in the area Sustainability. Actions for mitigating the risks of climate change The issues of energy safety and climate change, with the related greenhouse gas emissions, are the central issues of the development of energy systems. Eni defined and adopted a carbon management strategy with the following goals: preferably develop fossil fuels with low carbon intensity, in particular natural gas; pursue gas-electricity integration exploiting the high efficiency of combined cycles and co-generation; actively participate in the emission trading system, promoting the reduction of emissions in its industrial plants; participate in projects based on CDM (Clean Development Mechanisms) and JI (Joint Implementation) foreseen by the Kyoto protocol; progressively reduce gas flaring and gas venting associated to oil production creating the conditions for selling that gas on local and international markets; |  | develop technologies for the separation and the geologic confinement of CO2; design and promote a sustainable energy system based on a wide array of sources and high efficiency techniques. Along these guidelines Eni achieved results that mark it as a low (direct and indirect) CO2 emission company. As concerns emission trading, Eni is one of the largest Italian and European operators. In Italy, it is the first company for industrial plants involved (60 plants, of these 58 in Italy). In order to participate to emission trading schemes, Eni developed a series of coordinated activities and an extensive management organization, that starts from each industrial plant, ascends to business units and is consolidated at corporate level. This organization passed its first test phase successfully in the first months of 2006, when emissions for 2005 were verified and trading took place. In addition to participating to European emission trading schemes, Eni is also developing a portfolio of projects for emission reduction based on flexible mechanisms under the Kyoto Protocol. In November 2006, the electricity generation project in Okpai in Nigeria was registered as CDM, as it uses associated gas, formerly flared. A first goal achieved in the reduction of emissions related to gas flaring and venting. Eni’s longer term strategy envisages the development of fuels with lower environmental impact and more efficient technologies for the production of hydrogen, the design and promotion of a sustainable energy system based on a wide array of sources and high efficiency techniques. Development of natural gas Consumption of natural gas has been increasing faster than consumption of oil. The growing use of natural gas is also an efficient response to the risk of climate change. Its high environmental sustainability, its abundance and the new transport technologies show that natural gas is the energy source with the highest growth potential of the next decades. Natural gas, in fact, is more efficient and less polluting that coal and will be increasingly used in main markets (in particular the United States and Europe) for power generation. Eni is engaged in developing activities and upgrading transport infrastructure in the natural gas segment, with the strategic objective of strengthening its leadership in Europe by maximizing the value of its portfolio of equity gas in Italy, Libya, Egypt and the

North Sea and of its long term supply contracts with large producers such as Gazprom, Sonatrach, Gasunie and Statoil. In the area of natural gas development, in addition to the mentioned agreement with Gazprom, Eni also entered an agreement for the expansion of the Damietta liquefaction plant in Egypt and signed a shareholders’ agreement for the construction of a liquefaction terminal at Brass, Nigeria. These agreements are especially relevant keeping into account Eni’s interest for developing liquefied natural gas and set the premises for an optimal use of new fields in Egypt and for Eni’s natural gas reserves in Nigeria. Innovation Technological innovation represents a cornerstone of Eni’s strategies. All the great strategic challenges of the next years and decades require imagination and creativity: from the environmental and climate emergencies to the more and more difficult access to hydrocarbon reserves large, but mainly controlled by producing countries; from the identification of relevant discontinuities in the production of energy from renewable sources to the optimization of production processes up to the solution of problems existing in countries where Eni has been present for a long time or where it recently entered. In order to attain these goals in 2006 Eni has deeply revised the organization of its R&D activities. On August 1, 2006 EniTecnologie was merged into Eni. The resources dedicated to research have been assigned to the various divisions according to the existing knowledge and current projects. Divisions have become directly responsible for R&D activities of up-mid-downstream oil and gas (including the environmental ones affecting their segments) and of their budgeting. At the same time the Strategies and Development Department of of Eni Corporate has been entrusted with the task of defining strategic guidelines for technological innovation at group level, of playing a controlling and monitoring role on projects and activities and of developing research in the field of new energy technologies. This department also directly manages the “Along with petroleum” program, aimed at identifying and developing research projects on the most advanced aspects of renewable energy sources and energy efficiency. In its meeting of November 23, 2006, Eni’s Board of Directors discussed and approved the strategic |  | guidelines included in the R&D Master Plan which identifies the main challenges that the energy sector will have to face in future years, the strategic priorities and the innovation objectives to support them. In 2006, Eni invested euro 222 million in research and development (euro 204 million in 2005), of these 39% were directed to the Exploration & Production segment, 32% to the Refining & Marketing segment, 22% to the Petrochemical segment and 7% to the Engineering & Construction segment. At December 31, 2006, a total of 1,160 persons were employed in research and development activities. In 2006 a total of 39 applications for patents were filed (26 in 2005). Among the initiatives undertaken, projects have been started in the area of production and marketing of new generation biofuels to be sold on the market in a few years. More detailed information on innovation is found on Eni’s website (www.eni.it) in the area Activities and Strategies and in the Report on Sustainability. Main initiatives in innovation in 2006 E&P Division Numeric and High Resolution Geophysical Prospecting Techniques The development of the simulator of oil systems “Steam 3D” has been completed. It allows to describe the evolution of complex geological structures in time. The first applications on the field allow to reduce exploration risk and to improve the geo-mechanical description of the field. Development continued of the proprietary CRS technology (3D Common Reflection Surface Stack) that aims at allowing prospecting in areas characterized by low seismic response. Advanced Drilling Systems and Well Testing The Geosteering project developed by Eni in joint venture with Shell aims at the development of technologies capable of providing geological information on not yet drilled strata (around the scalpel up to the surface) while drilling. In the first six months of 2006, various downhole prototypes have been prepared and in the second half of the year the technology was tested in the well. Testing will continue until the first half of 2007.

Sulphur management In 2006, the integrated research program Sulphur and H2S management in E&P operations related to the treatment of natural gas with high H2S content has been completed. An innovative proprietary system called Concrete Wall has been developed for the massive storage of sulphur and H2S bulk removal. In 2007 demonstration units for the treatment and storage of sulphur will be developed along with the study the behavior of materials in very sour environments and under extreme pressure and temperature conditions. Gas to liquids project (GTL) In 2006, with the cooperation of IFP/Axens, Eni completed the technology handbook for this proprietary technology for the conversion of gas to liquids via Fischer-Tropsch synthesis and the plan for a 37 kbbl/d industrial unit. Conversion of heavy crudes and fractions into light products (in cooperation with the R&M Division) Testing continued at the Taranto demonstration plant of Eni’s proprietary technology EST, a process of catalytic hydroconversion in the slurry phase of non conventional crudes, extra heavy crudes and refining residues that allows to convert asphaltenes (the hard fraction of heavy crudes) totally into naphtha, kerosene, diesel fuel. In 2007 Eni plans to complete the collection of information for designing and building its first industrial plant. SCT-CPO Project (Short Contact Time - Partial Catalytic Oxidation) (in cooperation with the R&M Division) At the Milazzo research center, SCT-CPO (partial catalytic oxidation with short contact time of liquid and gaseous hydrocarbons) technology has been validated on the pilot scale for producing hydrogen at competitive costs, also in medium to small sized plants with higher flexibility as compared to refinery feedstocks. In 2007, Eni plans to complete the collection of information for designing and building its first industrial plant. GHG Project (Green House Gases) (in cooperation with the R&M Division) Work continued on the integrated Green House Gases research program, aimed at verifying the industrial feasibility of the geological sequestration of CO2 in depleted fields and salty aquifers. The technical |  | feasibility study of the geological sequestration of CO2 has been completed and in 2007, Eni expects to start testing in the field. G&P Division Natural gas high pressure transport (TAP) The TAP project will contribute to developing the most advanced long distance, high capacity, high pressure and high grade solutions with relevant targets related to: transport on distances over 3,000 kilometers; natural gas volumes to be transported of about 20-30 billion cubic meters/year; pressure equal to or higher than 15 MPa; use of high and very high grade steel. The TAP technology is expected to allow a decrease in the consumption of natural gas used in compressor stations. In 2006, testing continued on two infrastructure (one integrated in the system of Snam Rete Gas), the first technology handbook version was published and a hypothetical 3,400 kilometer long gasline in X100 steel in Central Asia was designed. R&M Division Reformulation of fuels and lubricants Eni continued to improve its “Blu” fuels (BluDiesel and BluSuper). It also started a new phase of its clean diesel fuel program that aims at identifying the optimal formula for a diesel fuel with high performance and low particulate emissions using as benchmark GTL Fischer-Tropsch gasoil (obtained from the conversion of natural gas into liquids - GTL project). Research will be applied also to the identification of refining schemes for obtaining this product. Other projects Green Diesel - the project aims at the production of biodiesel in refineries by means of a new hydrocracking process for vegetable oils developed in cooperation with an international partner; Ensolvex - aimed at the further industrial application of the process for the reclaiming of soils polluted by organic substances; EWMS (Early Warning Monitoring System) - in-field application of the outcome of research on remote monitoring and advanced control.

Two new grade of styrene isoprene copolymers have been consolidated at industrial level for the segment of hot melt adhesives. Two new grades of styrene butadiene copolymers have been tested in an industrial plant for the compounding application in the segment of hot melt adhesives. The first industrial testing of an ethylene propylene copolymer has been successful. New co-polymers of ethylene have been produced by means catalytic Ziegler/Natta system for injection moulding and for the following specialist application segments: bioriented films, high performance film cast and medium density lamination. Corporate In addition to the preparation of the R&D Master Plan, corporate activities were focused on the definition of research projects in the field of solar energy conversion and manufacture of new generation biofuels, that are due to start in 2007. Territory and Communities Eni operates in over 70 countries respecting the human rights of populations, their territory and the environment, contributing to improving the quality of life and the socio-economic development of the communities where it is present. This commitment is the basis of corporate behaviors based on the respect for |  | ethnic, social or cultural diversity of the various communities with which Eni interacts. The search for integration with varied social and cultural situations is part of Eni’s tradition. In order to favor a proper integration Eni: cooperates with national and local authorities and with international NGOs; sponsors initiatives that will proceed autonomously in the social, cultural and environmental fabric of the different communities; promotes dialogue with local communities on the industrial options by means of tools for active participation; favors the improvement of the socio-economic systems where it operates using wherever possible local goods and services, consistently with its industrial requirements, in order to maximize local content; extends the initiatives for its personnel to their families and to local communities where it operates, in particular as concerns health. Eni’s main interventions for the protection and development of local communities concern: Italy: activities included in the intent protocol signed with the Basilicata Region for the Val d’Agri for an overall expenditure of approximately euro 160 million in the 1999-2019 period; Karachaganak: infrastructure projects requested by the local authorities for an overall expenditure of approximately euro 9 million, paid by the Consortium; Caspian Sea: infrastructure projects requested by the local authorities for an overall expenditure of approximately euro 309 million, paid by the Consortium; Libya: recruiting, training, health assistance, archaeology, industrial development, as provided for by the masterplan for an overall expenditure of approximately euro 110 million for a period of eight years. Aware of its role of member of a social community, in 2006 Eni established Eni Foundation, an entity that autonomously promotes and carries out social initiatives with specific attention to childhood and old age in Italy and abroad. More detailed information on such initiatives is found on Eni’s website in the section Sustainability and in the Report on Sustainability.

Foreword The main risks identified and managed by Eni are the following: (i) market risks deriving from the exposure to the fluctuations of interest rates, of exchange rates between the euro and the US dollar and the other currencies used by the company, as well as the volatility of commodity prices; (ii) the credit risk deriving from the possible default of a counterparty; (iii) the liquidity risk deriving from the risk that suitable sources of funding for the Group’s business activities may not be available; (iv) the operation risk deriving from the occurrence of accidents, malfunctioning, failures with damage to persons and the environment affecting operating and financial results; (v) the country risk in oil & gas activities. Market risk Market risk is the possibility that changes in currency exchange rates, interest rates or oil, natural gas and power prices will adversely affect the value of the group’s financial assets, liabilities or expected future cash flows. Their management follows a set of guidelines and procedures based on a framework envisaging centralization of the treasury function in two captive finance companies operating in the Italian and international financial markets. In particular, the finance company operating on the domestic market (Enifin) manages all the transactions concerning currencies and derivative financial contracts. The commodity risk is managed by each business unit while Enifin manages the negotiation of hedging derivatives. Starting on January 1, 2007, this task is being performed by Eni SpA following the incorporation of Enifin. In order to minimize market risks related to changes |  | in interest rates and exchange rates and to manage exposure to commodity prices fluctuations, Eni enters into various transactions using derivative financial instruments (derivatives). Derivatives are contracts whose value is derived from one or more underlying financial instruments, indices or prices that are defined in the contract. The group also trades derivatives in conjunction with these risk management activities. Eni does not enter into derivative transactions on a speculative basis. The framework defined by Eni’s guidelines prescribes that measurement and control of market risk are to be performed on the basis of maximum acceptable levels of risk exposure defined in accordance with value-at-risk techniques. These techniques make a statistical assessment of the market risk, i.e., potential gain or loss in fair values. Eni’s guidelines prescribe that Eni’s subsidiaries use such market risk exposure policies as to minimize market risk. Tolerable market risk exposure is set at the Group level within the central finance department which pools all risk positions of the Group. Calculation and measurement techniques followed by Eni in accordance with established banking standards (such standards are established by the Basel Committee). However, the tolerable level of risk adopted by Eni is more conservative than the recommended one. Eni’s guidelines prescribe that the exposure to risk from fluctuations in commodity prices is to be managed in a way as to support the effectiveness of operations and to pursue set objectives of industrial margins. Risk exposure within trading activities is defined within maximum levels of value-at-risk attributed at each

business unit, with the central function managing hedging request. Strategic risk exposure is monitored in terms of value-at-risk, albeit not being hedged in a systematic way. Exchange rate risk Exchange rate risk derives from the fact that Eni’s operations are conducted in currencies other than the euro (in particular the US dollar) and by the time lag existing between the recording of costs and revenues denominated in currencies other than the functional currency and the actual time of the relevant monetary transaction (transaction exchange rate risk). Generally speaking, an appreciation of the US dollar versus the euro has a positive impact on Eni’s results of operations, and vice-versa. Effective management of exchange rate risk is performed at the Group level, within the central finance department which matches opposite positions of the Group operating subsidiaries and hedges net positions using derivatives (such as currency swaps, forwards and options). Such derivatives are recognized at fair value on the basis of market prices provided by specialized sources. Value-at-risk deriving from currency exposure is measured daily on the basis of a variance/covariance model, with a 99% confidence level and a 20-day holding period. The transaction currency risk on certain strategic holdings is deemed to be immaterial. Interest rate risk Variations in interest rates affect the market value of financial assets and liabilities of the company and the level of finance charges. Eni uses interest rate derivatives such interest rate swaps and interest cross currency swaps to effectively manage the balance between fixed and floating rate debt. Such derivatives are recognized at fair value on the basis of market prices provided from specialized sources. Value-at-risk deriving from interest rate exposure is measured daily on the basis of a variance/covariance model, with a 99% confidence level and a 20-day holding period. Commodity risk Eni’s results of operations are affected by changes in the prices of commodities. A decrease in oil, gas and products prices generally has a negative impact on Eni’s results of operations and vice-versa. In order to hedge commodity risk, Eni uses derivatives traded on the organized markets of ICE and NYMEX (futures and options) and derivatives traded over-the-counter (swaps, forwards and contracts for differences, with the |  | underlying commodities being crude oil, refined products or electricity. Such derivatives are recognized at fair value on the basis of market prices provided from specialized sources or absent market prices, on the basis of estimates provided by brokers or suitable evaluation techniques. Value-at-risk deriving from commodity exposure is measured daily on the basis of a historical simulation technique, with a 99% confidence level and a one-day holding period. Credit risk Credit risk is the potential exposure of the Group to loss in the event of non-performance by a counterparty. The credit risk arising from the Group’s normal commercial operations is controlled by individual operating units within Group-approved guidelines. The monitoring activity of credit risk exposure is performed at the Group level according to set guidelines and measurement techniques. In particular, credit risk exposure to large clients and multi-business clients is monitored at the Group level on the basis of score cards quantifying risk levels. Eni’s guidelines define the characteristics of persons eligible to be counterparty of Eni in derivative contracts and cash management transactions. Eni constantly updates a list of eligible persons which includes highly credit-rated institutions. Eni has not experienced material non-performance by any counterparty. As of December 31, 2005 and December 31, 2006, Eni has no significant concentrations at credit risk. Liquidity risk Liquidity risk is the risk that suitable sources of funding for the group’s business activities may not be available. The group has long-term debt ratings of AA and Aa2, assigned respectively by Standard & Poor’s and Moody’s. The group has access to a wide range of funding at competitive rates through the capital markets and banks. It coordinates relationships with banks, borrowing requirements, foreign exchange requirements and cash management centrally. At present, the Group believes it has access to sufficient funding and has also both committed and uncommitted borrowing facilities to meet currently foreseeable borrowing requirements. Effective management of the liquidity risk has the objective of ensuring the availability of adequate funding to meet short term requirements and due obligations and also the objective of ensuring a sufficient level of flexibility in order to fund the development plans of the Group businesses. This implies the adoption of a strategy for pursuing

an adequate structure of borrowing facilities (particularly the availability of committed borrowings facilities) and the maintenance of cash reserves. Country risk Substantial portions of Eni’s hydrocarbons reserves are located in countries outside the EU and North America, certain of which may be politically or economically less stable than EU or North American countries. At December 31, 2006, approximately 70% of Eni’s proved hydrocarbons reserves were located in such countries. Similarly, a substantial portion of Eni’s natural gas supplies comes from countries outside the EU and North America. In 2006, approximately 60% of Eni’s domestic supply of natural gas came from such countries. Negative developments in the economic and political framework of these countries can compromise temporarily or permanently Eni’s ability to operate economically and to have access to oil and natural gas reserves. Eni monitors constantly the political, social and economic risk of the approximately 60 countries where it invested or intends to invest with special attention to the evaluation of upstream investments. Country risks are mitigated by means of appropriate guidelines for risk management that Eni defined in its procedure for project risk assessment and management. Operation risk The broad scope of Eni’s activities involves a wide range of operational risks such as those of explosion, fire or leakage of toxic products, production of non biodegradable waste. All these events could possibly damage or even destroy plants, facilities, equipment and other property, cause injury or even death to persons or cause environmental damage. Eni adopted the most stringent guidelines for the |  | evaluation and management of health, safety and environmental (HSE) risks, with the objective of protecting Eni’s employees, contractors and clients the populations involved in its activity and the environment and being in compliance with local and international rules and regulations. Eni’s guidelines prescribe the adoption of international best practices in setting internal principles, standards and solutions. An ongoing process for identifying, evaluating and managing HSE risks is at the hearth of HSE operations in each phase of the business activity and is performed through the adoption of procedures tailored on the peculiarities of each business and industrial site. HSE risks are effectively managed through an integrated management system designed along the principles set in Eni’s Model of HSE operations. This is a general procedure to be applied in all operating sites, based on an annual cycle of planning, implementation, control, review of results and definition of new objectives. The model is directed towards the prevention of risks, the systematic monitoring and control of HSE performance in a continuous improvement cycle, also subject to audits by internal and independent experts. Any environmental emergency is managed by business units locally with their own organization under preset reaction plans to foreseeable events aimed at limiting damage and at activating adequate responses. Eni has two emergency rooms (in Milan and Rome) provided with real-time monitoring systems for the collection of data on georeferenced maps for all Eni sites and logistics worldwide. Meteorologic equipment is in place to assess dimension, temporal development and other consequences of certain catastrophic events and to enable a real-time planning of first-aid interventions to help mitigate consequences. In addition to its own emergency teams, Eni entered international agreements in order to maximize its ability to react in all its operating sites.

ENI ANNUAL REPORT / GLOSSARY

Glossary The glossary of oil and gas terms is available on Eni’s web page at the address www.eni.it. Below is a selection of the most frequently used terms. FINANCIAL TERMS Dividend Yield Measures the return on a share based on dividends for the year. Calculated as the ratio of dividends per share of the year and the average reference price of shares in the last month of the year. Leverage Is a measure of a company’s debt, calculated as the ratio between net financial debt and shareholders’ equity, including minority interests. ROACE Return On Average Capital Employed is the return on average capital invested, calculated as the ratio between net income before minority interests, plus net financial charges on net financial debt, less the related tax effect and net average capital employed. TSR Total Shareholder Return measures the total return of a share calculated on a yearly basis, keeping account of changes in prices (beginning and end of year) and dividends distributed and reinvested at the ex-dividend date. OIL AND NATURAL GAS ACTIVITIES Average reserve life index Ratio between the amount of reserves at the end of the year and total production for the year. Barrel Volume unit corresponding to 159 liters. A barrel of oil corresponds to about 0.137 metric tons. Boe (Barrel of Oil Equivalent) Is used as a standard unit measure for oil and natural gas. The latter is converted from standard cubic meters into barrels of oil equivalent using a coefficient equal to 0.00615. Concession contracts Contracts currently applied mainly in Western countries regulating relationships between States and oil companies with regards to hydrocarbon exploration and production. The company holding the mining concession has an exclusive on mining activities and for this reason it acquires a right on hydrocarbons |  | extracted, against the payment of royalties to the State on production and taxes on oil revenues. Condensates These are light hydrocarbons produced along with gas, that condense to a liquid state at normal temperature and pressure for surface production facilities. Deep waters Waters deeper than 200 meters. Development Drilling and other post-exploration activities aimed at the production of oil and gas. Elastomers (or Rubber) Polymers, either natural or synthetic, which, unlike plastic, when stress is applied, return to their original shape, to a certain degree, once the stress ceases to be applied. The main synthetic elastomers are polybutadiene (BR), styrene-butadiene rubbers (SBR), ethylene-propylene rubbers (EPR), thermoplastic rubbers (TPR) and nitrylic rubbers (NBR). Enhanced recovery Techniques used to increase or stretch over time the production of wells. EPC (Engineering, Procurement, Construction) A contract typical of onshore construction of large plants in which the contractor supplies engineering, procurement and construction of the plant. The contract is defined “turnkey” when the plant is supplied for start-up. EPIC (Engineering, Procurement, Installation, Commissioning) A contract typical of offshore construction of complex projects (such as the installation of production platforms or FPSO systems) in which the global or main contractor, usually a company or a consortium of companies, supplies engineering, procurement, construction of plant and infrastructure, transport to the site and all preparatory activities for the start-up of plants. Exploration Oil and natural gas exploration that includes land surveys, geological and geophysical studies, seismic data gathering and analysis, and well drilling. FPSO vessel Floating, Production, Storage and Offloading system made up of a large capacity oil tanker including a large hydrocarbon treatment plant. This system, moored at the bow in order to maintain a geostationary position, is in fact a temporary fixed platform linking by means of risers

from the seabed the underwater wellheads to the treatment, storage and offloading systems onboard. Infilling wells Infilling wells are wells drilled in a producing area in order to improve the recovery of hydrocarbons from the field and to maintain and/or increase production levels. LNG Liquefied Natural Gas obtained through the cooling of natural gas to minus 160 °C at normal pressure. The gas is liquefied to allow transportation from the place of extraction to the sites at which it is transformed and consumed. One ton of LNG corresponds to 1,400 cubic meters of gas. LPG Liquefied Petroleum Gas, a mix of light petroleum fractions, gaseous at normal pressure and easily liquefied at room temperature through limited compression. Mineral Potential (“Potentially recoverable hydrocarbon volumes”) Estimated recoverable volumes which cannot be defined as reserves due to a number of reasons, such as the temporary lack of viable markets, a possible commercial recovery dependent on the development of new technologies, or for their location in accumulations yet to be developed or where evaluation of known accumulations is still at an early stage. Mineral Storage Volumes of natural gas required for allowing optimal operation of natural gas fields in Italy for technical and economic reasons. Modulation Storage Volumes of natural gas required for meeting hourly, daily and seasonal swings of demand. Natural gas liquids Liquid or liquefied hydrocarbons recovered from natural gas through separation equipment or natural gas treatment plants. Propane, normal-butane and isobutane, isopentane and pentane plus, that used to be defined natural gasoline, are natural gas liquids. Network Code A code containing norms and regulations for access to, management and operation of natural gas pipelines. Offshore/Onshore The term offshore indicates a portion of open sea and, by induction, the activities carried out in such area, while onshore refers to land operations. |  | Olefins (or Alkenes) Hydrocarbons that are particularly active chemically, used for this reason as raw materials in the synthesis of intermediate products and of polymers. Over/Underlifting Agreements stipulated between partners regulate the right of each to its share in the production of a set period of time. Amounts different from the agreed ones determine temporary over/underlifting situations. Possible reserves Amounts of hydrocarbons that have a lower degree of certainty than probable reserves and are estimated with lower certainty, for which it is not possible to foresee production. Probable reserves Amounts of hydrocarbons that are probably, but not certainly, expected to be extracted. They are estimated based on known geological conditions, similar characteristics of rock deposits and the interpretation of geophysical data. Further uncertainty elements may concern: (i) the extension or other features of the field; (ii) economic viability of extraction based on the terms of the development project; (iii) existence and adequacy of transmission infrastructure and/or markets; (iv) the regulatory framework. Production Sharing Agreement Contract in use in non OECD area countries, regulating relationships between States and oil companies with regard to the exploration and production of hydrocarbons. The mining concession is assigned to the national oil company jointly with the foreign oil company who has exclusive right to perform exploration, development and production activities and can enter agreements with other local or international entities. In this type of contract the national oil company assigns to the international contractor the task of performing exploration and production with the contractor’s equipment and financial resources. Exploration risks are borne by the contractor and production is divided into two portions: “cost oil” is used to recover costs borne by the contractor, “profit oil” is divided between contractor and national company according to variable schemes and represents the profit deriving from exploration and production. Further terms and conditions may vary from one country to the other. Proved reserves Proved reserves are estimated volumes of crude oil, natural gas and gas condensates, liquids and associated substances which are expected to be

127

retrieved from deposits and used commercially, at the economic and technical conditions applicable at the time of the estimate and according to current legislation. Proved reserves include: (i) proved developed reserves: amounts of hydrocarbons that are expected to be retrieved through existing wells, facilities and operating methods; (ii) non developed proved reserves: amounts of hydrocarbons that are expected to be retrieved following new drilling, facilities and operating methods. On these amounts the company has already defined a clear development expenditure program which is expression of the company’s determination. Recoverable reserves Amounts of hydrocarbons included in different categories of reserves (proved, probable and possible), without considering their different degree of uncertainty. Reserve replacement ratio Measure of the reserves produced replaced by proved reserves. Indicates the company’s ability to add new reserves through exploration and purchase of property. A rate higher than 100% indicates that more reserves were added than produced in the period. The ratio should be averaged on a three-year period in order to reduce the distortion deriving from the purchase of proved property, the revision of previous estimates, enhanced recovery, improvement in recovery rates and changes in the value of reserves – in PSAs – due to changes in international oil prices. Management also calculates this ratio by excluding the effect of the purchase of proved property in order to better assess the underlying performance of the Company’ s operations. Ship-or-pay Clause included in natural gas transportation contracts according to which the customer for which the transportation is carried out is bound to pay for the transportation of the gas also in case the gas is not transported. Strategic Storage Volumes of natural gas required for covering lack or reduction of supplies from extra-European sources or crises in the natural gas system. |  | Swap In the gas sector, the swap term is referred to a buy/sell contract between some counterparties and is generally aimed to the optimization of transport costs and respective commitments in purchasing and supplying. Take-or-pay Clause included in natural gas transportation contracts according to which the purchaser is bound to pay the contractual price or a fraction of such price for a minimum quantity of the gas set in the contract also in case it is not collected by the customer. The customer has the option of collecting the gas paid and not delivered at a price equal to the residual fraction of the price set in the contract in subsequent contract years. Upstream/Downstream The term upstream refers to all hydrocarbon exploration and production activities. The term downstream includes all activities inherent to the oil sector that are downstream of exploration and production activities. Wholesale sales Domestic sales of refined products to wholesalers/distributors (mainly gasoil), public administrations and end consumers, such as industrial plants, power stations (fuel oil), airlines (jet fuel), transport companies, big buildings and households. They do not include distribution through the service station network, marine bunkering, sales to oil and petrochemical companies, importers and international organizations. Workover Intervention on a well for performing significant maintenance and substitution of basic equipment for the collection and transport to the surface of liquids contained in a field.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Basis of presentation
The Consolidated Financial Statements of Eni have been prepared in accordance with IFRS issued by the International Accounting Standards Board (IASB) and adopted by the European Commission following the procedure contained in Article 6 of the EC Regulation No. 1606/2002 of the European Parliament and Council of July 19, 2002 and in accordance with Article 9 of Legislative Decree No. 38/2005. For hydrocarbon exploration and production, accounting policies followed at an international level have been applied, with particular reference to amortization according to the Unit-Of-Production method, buy-back contracts and Production Sharing Agreements.
The Consolidated Financial Statements have been prepared by applying the cost method except for items that under IFRS must be recognized at fair value as described in the evaluation criteria.
The Consolidated Financial Statements include the statutory accounts of Eni SpA and of all Italian and foreign companies in which Eni SpA holds the right to directly or indirectly exercise control, determine financial and management decisions and obtain economic and financial benefits.
Insignificant subsidiaries are not included in the scope of consolidation. A subsidiary is considered insignificant when it does not exceed two of these limits: (i) total assets or liabilities: euro 3,125 thousand; (ii) total revenues: euro 6,250 thousand; (iii) average number of employees: 50 units. Moreover, companies for which consolidation does not produce significant economic and financial effects are not included in the scope of consolidation. Such companies generally represent subsidiaries that work on account of other companies as the sole operator in the management of upstream oil contracts; these companies are financed on a proportional basis according to budgets approved, by the companies involved in the project, to which the company periodically reports costs and receipts deriving from the contract. Costs and revenues and other operating data (production, reserves, etc.) of the project, as well as the obligations arising from the project, are recognized proportionally in the Financial Statements of the companies involved. The effects of these exclusions are not material1.
Subsidiaries excluded from consolidation, joint ventures, associates and other interests are accounted for as described below under item “Financial fixed assets”.
Financial Statements of consolidated companies are audited by auditing companies that examine and certify the information required to be disclosed when preparing the consolidated financial statement.
Considering their materiality, amounts of the financial statements and related disclosures are expressed in millions of euro.
Principles of consolidation
Interests in companies included in the scope of consolidation
Assets and liabilities, expense and income related to fully consolidated companies are wholly incorporated into the Consolidated Financial Statements; the book value of these interests is eliminated against the corresponding fraction of the shareholders’ equity of the companies owned, attributing to each item of the balance sheet the current value at the date of acquisition of control. Any positive residual difference as regards to the acquisition cost is recognized as “Goodwill”. Negative residual differences are charged against the profit and loss account.
Any positive residual difference between cost for the acquisition of the share that exceed the control (minorities acquisition) and corresponding fraction of shareholders’ equity acquired is recognized as “Goodwill”.
Gains or losses on the sale of shares in consolidated subsidiaries are recorded in the profit and loss account for the amount corresponding to the difference between proceeds from the sale and divested portion of net equity sold.
Fractions of shareholders’ equity and net profit of minority interest are recognized under specific items in the Financial Statements. Minority interest is determined based on the current value attributed to assets and liabilities at the date of the acquisition of control, excluding any related goodwill.

Inter-company transactions
Income deriving from inter-company transactions unrealized towards third parties is eliminated. Receivables, payables, revenues and costs, guarantees, commitments and risks among consolidated companies are eliminated as well. Inter-company losses are not eliminated, since they reflect an actual decrease in the value of divested assets.

(1) |  | According to the requirements of the framework of international accounting standards, information is material if its omission or misstatement can influence the economic decisions that users make on the basis of the financial statements.

Foreign currency translation
Financial Statements of consolidated companies denominated in currencies other than the euro are converted into euro applying exchange rates prevailing at the year end to assets and liabilities, the historical exchange rates to equity accounts and the average rates for the period to profit and loss account (source: Ufficio Italiano Cambi).
Exchange rate differences from the conversion deriving from the application of different exchange rates for assets and liabilities, shareholders’ equity and profit and loss account are recognized under the item “Other reserves” within shareholders’ equity for the portion relating to the Group and under the item “Minority interest” for the portion related to minority shareholders. The exchange rate differences reserve is charged to the profit and loss account when the investments are sold or the capital employed is repaid.
Financial Statements of foreign subsidiaries which are translated into euro are denominated in the functional currencies of the country where the enterprise operates. The US dollar is the prevalent functional currency for the enterprises that do not adopt the euro.
Evaluation criteria
The most significant evaluation criteria used for the preparation of the Consolidated Financial Statements are shown below.
Current assets
Financial assets held for trading and financial assets available for sale are stated at fair value; economic effects are charged to the profit and loss account item “Financial Income (Expense)” and under shareholders’ equity within “Other reserves”. In the last case, changes in fair value recognized under shareholders’ equity are charged to the profit and loss account when they are impaired or realized.
The fair value of financial instruments is represented by market quotations or, in their absence, by the value resulting from the adoption of suitable financial valuation models which take into account all the factors adopted by the market operators and the prices obtained in similar actual transactions in the market.
When the conditions for the purchase or sale of financial assets provide for the settlement of the transaction and the delivery of the assets within a given number of days determined by entities controlling the market or by agreements (e.g., purchase of securities on regulated markets), the transaction is entered at the date of settlement.
Receivables are stated at their amortized cost (see item “Financial fixed assets” below).
Transferred financial assets are eliminated when the transaction, together with the cash flows deriving from it, leads to the substantial transfer of all risks and benefits associated to the property.
Inventories, excluding contract work in progress and including compulsory stocks, are stated at the lower of purchase or production cost and net realizable value represented by the proceeds the company expects to collect from the sale of the inventories in the normal course of business.
The cost of inventories of hydrocarbons (crude oil, condensates and natural gas) and petroleum products is determined by applying the weighted-average cost method on a three-month basis; the cost of inventories of the Petrochemical segment is determined by applying the weighted-average cost on an annual basis.
Contract work in progress is recorded on the basis of contractual considerations by reference to the stage of completion of a contract measured on a cost-to-cost basis. Advances are deducted from inventories within the limits of contractual considerations; any excess of such advances over the value of the work performed is recorded as a liability. Losses related to construction contracts are accrued for once the company becomes aware of such losses. Contract work in progress not yet invoiced, whose payment is agreed in a foreign currency, is translated to euro using the current exchange rates at year end and effects are charged in the profit and loss account.
Hedging instruments are described in the section “Derivative Instruments”.

Non-current assets
Property, plant and equipment2
Tangible assets, including investment properties, are recognized using the cost model and stated at their purchase or production cost including ancillary costs which can be directly attributed to them as required to make the asset ready for use. In addition, when a substantial amount of time is required to make the asset ready for use, the purchase price or production cost includes the financial expenses incurred that would have theoretically been saved if the investment had not been made.
In the case of current obligations for the dismantling and removal of assets and the reclamation of sites, the carrying value includes, with a corresponding entry to a specific provision, the estimated (discounted) costs to be borne at the moment the asset is retired. Revisions of estimates for these provisions, for the passage of time and for changes in the discount rate are recognized under “Provisions for contingencies”3.
No revaluation is made even in application of specific laws.
Assets carried under financial leasing or concerning arrangements that does not take the legal form of a financial lease but produce a substantive transfer of risks and rewards of ownership, are recognized at fair value, net of taxes due from the lessor or, if lower, at the amount of future minimum lease payments, and are included within the tangible assets, with a corresponding entry to the financial payable to the lessor, and depreciated using the criteria detailed below. When the renewal is not reasonably certain, assets carried under financial leasing are depreciated over the period of the lease if shorter than the useful life of the asset.
Renewals, improvements and transformations which extend asset lives are capitalized.
Tangible assets, commencing on the date when they begin or should begin to be used, are depreciated systematically based on the straight-line method over the duration of their useful life taken as an estimate of the period for which the assets will be used by the company. When tangible asset are comprised of more than one significant element with different useful lives, the depreciation is carried out for each component. The amount to be depreciated is represented by the book value reduced by the presumable net realizable value at the end of the useful life, if it is significant and can be reasonably determined. Land is not depreciated, even if purchased together with a building. Tangible assets held for sales are not depreciated but are valued at the lower of the book value and fair value less costs of disposal.
Assets that can be used free of charge are depreciated over the shorter term of the duration of the concession and the useful life of the asset.
The costs for the substitution of identifiable components in complex assets are capitalized and depreciated over their useful life; the residual book value of the component that has been substituted is charged to the profit and loss account. Ordinary maintenance and repair costs are expensed when incurred.
When events occur that lead to a presumable reduction in the book value of tangible assets, their recoverability is checked by comparing their book value with the realizable value, represented by the greater of fair value less costs of disposal and value in use. In the absence of a binding sales agreement, fair value is estimated on the basis of market values, recent transactions, or the best available information that shows the proceeds that the company could reasonably expect to collect from the disposal of asset. Value in use is determined by discounting the expected cash flows deriving from the use of the asset and, if significant and reasonably determinable, the cash flows deriving from its disposal at the end of its useful life, net of disposal costs. Cash flows are determined on the basis of reasonable and documented assumptions that represent the best estimate of the future economic conditions during the residual useful life of the asset, giving more importance to independent assumptions. Discounting is carried out at a rate that takes into account the implicit risk in the sectors where the entity operates. Valuation is carried out for each single asset or, if the realizable value of a single asset cannot be determined, for the smallest identifiable group of assets that generates independent cash inflows from their continuous use, the so called “cash generating unit”. When the reasons for their impairment cease to exist, Eni reverses previously recorded impairment charges and records as income of an asset revaluation in the profit and loss account for the relevant year. This asset revaluation is the lower of the fair value and the book value increased by the amount of previously incurred impairments net of related amortization that would have been made if the impairment had not been made.

(2) |  | Recognition and evaluation criteria of exploration and production activities are described in the section “Exploration and production activities” below.
(3) |  | The company recognizes material provisions for the retirement of assets in the Exploration & Production business. No significant asset retirement obligations associated with any legal obligations to retire refining, marketing and transportation (downstream) and chemical long-lived assets generally are recognized, as indeterminate settlement dates for the asset retirements prevented estimation of the fair value of the associated asset retirement obligation. The company performs periodic reviews of its downstream and chemical long-lived assets for any changes in facts and circumstances that might require recognition of a retirement obligation.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Intangible assets
Intangible assets include assets which lack identifiable physical qualities, controlled by the company and able to produce future economic benefits, and goodwill acquired in business combinations. An asset is classified as intangible when the management is able to distinguish it clearly from goodwill. This condition is normally met when: (i) the intangible asset can be traced back to a legal or contractual right, or (ii) the asset is separable, i.e., can be sold, transferred, licensed, rented or exchanged, either individually or as an integral part of other assets. An entity controls an asset if it has the power to obtain the future economic benefits flowing from the underlying resource and to restrict the access of others to those benefits.
Intangible assets are stated at cost as determined with the criteria used for tangible assets. No revaluation is made even in application of specific laws.
Intangible assets with a defined useful life are amortized systematically over the duration of their useful life taken as an estimate of the period for which the assets will be used by the company; the recoverability of their book value is checked using the criteria described in the section “Tangible Assets”.
Goodwill and other intangible assets with an indefinite useful life are not amortized. The recoverability of their carrying value is checked at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. With reference to goodwill, this check is performed at the level of the smallest aggregate on which the company, directly or indirectly, evaluates the return on the capital expenditure that included said goodwill. When the carrying amount of the cash generating unit, including goodwill attributed thereto, exceeds the cash generating unit's recoverable amount, the difference is recognized as impairment and it is primarily charged against goodwill up to its amount; any amount in excess is charged on a pro-rata basis against the book value of the assets that form the cash generating unit. Impairment charges against goodwill are not revalued. Negative goodwill is recognized in the profit and loss account.
Costs of technological development activities are capitalized when: (i) the cost attributable to the intangible asset can be reasonably determined; (ii) there is the intention, availability of funding and technical capacity to make the asset available for use or sale; and (iii) it can be shown that the asset is able to produce future economic benefits.
Exploration and production activities4
ACQUISITION OF MINERAL RIGHTS
Costs associated with the acquisition of mineral rights are capitalized in connection with the assets acquired (such as exploratory potential, probable and possible reserves and proved reserves). When the acquisition is related to a set of exploratory potential and reserves, the cost is allocated to the different assets acquired on the basis of the value of the relevant discounted cash flows.
Expenditure for the exploratory potential, represented by the costs for the acquisition of the exploration permits and for the extension of existing permits, is recognized under “Intangible Assets” and is amortized on a straight-line basis over the period of the exploration as contractually established. If the exploration is abandoned, the residual expenditure is charged to the profit and loss account.
Acquisition costs for proved reserves and for possible and probable reserves are recognized in the balance sheet as assets. Costs associated with proved reserves are amortized on a Unit of Production (UoP) basis, as detailed in the section “Development”, considering both developed and undeveloped reserves. Expenditures associated with possible and probable reserves are not amortized until classified as proved reserves; in case of a negative result, the costs are charged to the profit and loss account.
EXPLORATION
Costs associated with exploratory activities for oil and gas producing properties incurred both before and after the acquisition of mineral rights (such as acquisition of seismic data from third parties, test wells and geophysical surveys) are capitalized, to reflect their nature of investment and amortized in full when incurred.
DEVELOPMENT
Development costs are those costs incurred to obtain access to proved reserves and to provide facilities for extracting, gathering and storing oil and gas. They are then capitalized and amortized generally on a UoP basis, as their useful life is closely related to the availability of feasible reserves. This method provides for residual costs at the end of each quarter to be amortized through a rate representing the ratio between the volumes extracted during the quarter and the proved developed reserves existing at the end of the quarter, increased by the volumes extracted during the quarter. This method is applied with reference to the smallest aggregate representing a direct correlation between investment and proved developed reserves.

(4) |  | International accounting principles do not establish specific criteria for hydrocarbon exploration and production activities. Eni continues to use existing accounting policies for exploration and evaluation assets previously applied before the introduction of IFRS, as permitted by IFRS 6 “Exploration for and evaluation of mineral resources”.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Costs related to unsuccessful development wells or damaged wells are expensed immediately as losses on disposal.
Impairments and reversal of impairments of development costs are made on the same basis as those for tangible assets.
PRODUCTION
Production costs are those costs incurred to operate and maintain wells and field equipment and are expensed as incurred.
PRODUCTION SHARING AGREEMENTS AND BUY-BACK CONTRACTS
Revenues and oil and gas reserves related to Production Sharing Agreements and buy-back contracts are settled on the basis of contractual clauses related to the repayment of costs incurred following the exploration, development and operating activities (cost oil) and to the relevant amount of realized productions (profit oil).
RETIREMENT
Costs expected to be incurred with respect to the retirement of a well, including costs associated with removal of production facilities, dismantlement and site restoration, are capitalized and amortized on a UOP basis, consistent with the policy described under “Tangible Assets”.
Grants
Grants related to assets are recorded as a reduction of purchase price or production cost of the related assets when there is reasonable assurance that all the required conditions attached to them, agreed upon with governmental entities, have been met. Grants not related to capital expenditure are recognized in the profit and loss account.
Financial fixed assets
INVESTMENTS
Investments in subsidiaries excluded from consolidation, joint ventures and associates are accounted for using the equity method. If it does not result in a misrepresentation of the company’s financial condition and consolidated results, subsidiaries, joint ventures and associates excluded from consolidation may be accounted for at cost, adjusted for impairment losses. When the reasons for their impairment cease to exist, investments accounted for at cost are revalued within the limit of the impairment made and their effects are charged to the profit and loss account item “Other income (expense) from investments”.
Other investments are recognized at their fair value and their effects are included in shareholders’ equity under “Other reserves”; this reserve is charged to the profit and loss account when it is impaired or realized. When fair value cannot be reasonably ascertained, investments are accounted for at cost, adjusted for impairment losses; impairment losses may not be revalued.
The risk deriving from losses exceeding shareholders’ equity is recognized in a specific provision to the extent the parent company is required to fulfill legal or implicit obligations towards the subsidiary or to cover its losses.
RECEIVABLES AND FINANCIAL ASSETS TO BE HELD TO MATURITY
Receivables and financial assets that must be held to maturity are stated at cost represented by the fair value of the initial exchanged amount adjusted to take into account direct external costs related to the transaction (e.g., fees of agents or consultants, etc.). The initial carrying value is then corrected to take into account capital repayments, impairments and amortization of the difference between the reimbursement value and the initial carrying value; amortization is carried out on the basis of the effective internal rate of return represented by the rate that equalizes, at the moment of the initial revaluation, the current value of expected cash flows to the initial carrying value (so-called amortized cost method). Any impairment is recognized by comparing the carrying value with the present value of the expected cash flows discounted at the effective interest rate defined at the initial recognition. The economic effects of the valuation according to the amortized cost method are charged to “Financial income (expense)”.
Financial liabilities
Debt is carried at amortized cost (see item “Financial fixed assets” above).
Provisions for contingencies
Provisions for contingencies concern risks and charges of a definite nature and whose existence is certain or probable but for which at year end the amount or date of occurrence remains uncertain. Provisions are made when: (i) there is a current obligation,

144

##### Contents

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

either legal or implicit, deriving from a past event; (ii) it is probable that the fulfillment of that obligation will result in an outflow of resources embodying economic benefits; and (iii) the amount of the obligation can be reliably estimated. Provisions are stated at the value that represents the best estimate of the amount that the company would reasonably pay to fulfill the obligation or to transfer it to third parties at year end. When the financial effect of time is significant and the payment date of the obligations can be reasonably estimated, the provisions are discounted back at the company’s average rate of indebtedness. The increase in the provision due to the passing of time is charged to the profit and loss account in the item “Financial Income (Expense)”.
When the liability regards a tangible asset (e.g., site restoration and abandonment), the provision is stated with a corresponding entry to the asset to which it refers; profit and loss account charge is made with the amortization process.
Costs that the company expects to bear in order to carry out restructuring plans are recognized in the year in which the company formally defines the plan and the interested parties have developed the reasonable expectation that the restructuring will happen.
Provisions are periodically updated to show the variations of estimates of costs, production times and actuarial rates; the estimated revisions to the provisions are recognized in the same profit and loss account item that had previously held the provision, or, when the liability regards tangible assets (i.e., site restoration and abandonment) with a corresponding entry to the assets to which they refer.
In the Notes to the Consolidated Financial Statements the following potential liabilities are described: (i) possible, but not probable obligations deriving from past events, whose existence will be confirmed only when one or more future events beyond the company’s control occur; and (ii) current obligations deriving from past events whose amount cannot be reasonably estimated or whose fulfillment will probably not result in an outflow of resources embodying economic benefits.
Employee benefits
Post-employment benefit plans are defined on the basis of plans, including those unformalized, that due to their terms defined contributions or defined benefits. In the first case, the company’s obligation, which consists of making payments to the State or a trust or a fund, is determined on the basis of contributions due.
The liabilities related to defined benefit plans5, net of any plan assets, are determined on the basis of actuarial assumptions and charged on accrual basis during the employment period required to obtain the benefits; the evaluation of liabilities is made by independent actuaries.
The actuarial gains and losses of defined benefit plans, deriving from a change in the actuarial assumptions used or from a change in the conditions of the plan, are charged to the profit and loss account, proportionally through the residual average working life of the employees participating to the plan, in the limits of the share of the discounted profit/loss not charged beforehand, that exceeds the greater of 10% of the fair value of liabilities and 10% of the fair value of the plan assets (corridor method).
Obligations for long-term benefits are determined by adopting actuarial assumptions; the effect of changes in actuarial assumptions or a change in the characteristics of the benefit are charged to the profit or loss in their entirety.
Treasury shares
Treasury shares are recorded at cost and as a reduction of shareholders’ equity. Gains following subsequent sales are recorded as an increase in shareholders’ equity.
Revenues and costs
Revenues from sales of products and services rendered are recognized upon transfer of risks and rewards associated to ownership or upon settlement of the transaction. In particular, revenues are recognized:

- for crude oil, generally upon shipment;

- for natural gas, when natural gas is delivered to the customer;

- for petroleum products sold to retail distribution networks, generally upon delivery to the service stations, whereas all other sales are generally recognized upon shipment;

- for petrochemical products and other products, generally upon shipment.

(5) |  | Given the uncertainties related to their payment date, employees termination indemnities are considered as a defined benefit plan.

145

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Revenues are recognized upon shipment when, at that date, the risks of loss are transferred to the acquirer. Revenues from the sale of crude oil and natural gas produced in properties in which Eni has an interest together with other producers are recognized on the basis of Eni’s working interest in those properties (entitlement method). Differences between Eni’s net working interest volume and actual production volumes are recognized at current prices at period end.
Income related to partially rendered services are recognized with respect to the accrued revenues, if it is possible to reasonably determine the state of completion and there are no relevant uncertainties concerning the amounts and the existence of the revenue and related costs; otherwise it is recognized within the limits of the recoverable costs incurred.
Revenues accrued in the period related to construction contracts are recognized on the basis of contractual revenues by reference to the stage of completion of a contract measured on the cost-to-cost basis. Requests of additional revenues, deriving from a change in the scope of the work, are included in the total amount of revenues when it is probable that the customer will approve the variation and the related amount; claims deriving for instance from additional costs incurred for reasons attributable to the client are included in the total amount of revenues when it is probable that the counterpart will accept them.
Revenues are stated net of returns, discounts, rebates and bonuses, as well as directly related taxation. Exchanges of goods and services with similar nature and value do not give rise to revenues and costs as they do not represent sale transactions.
Costs are recognized when the related goods and services are sold, consumed or allocated, or when their future useful lives cannot be determined. Costs related to the amount of emissions, determined on the basis of the average prices of the main European markets at the end of the period, are reported in relation to the amount of the carbon dioxide emissions that exceed the amount assigned; revenues related to the amount of emissions are reported when are recognized following the sale.
Operating lease payments are recognized in the profit and loss account over the length of the contract.
Labor costs include stock grants and stock options granted to managers, consistent with their actual remunerative nature. The cost is determined based on the fair value of the rights awarded to the employee at the date of the award and it is not subject to subsequent adjustments; the portion on an accrual basis is calculated pro rata over the period to which the incentive refers (vesting period)6. The fair value of stock grants is represented by the current value of the shares at the date of the award, reduced by the current value of the expected dividends in the vesting period. The fair value of stock options is the value of the option calculated with appropriate valuation techniques that take into account the exercise conditions, current price of the shares, expected volatility and the risk-free interest rate. The fair value of the stock grants and stock options is shown as a contra-entry to “Other reserves”.
The costs for the acquisition of new knowledge or discoveries, the study of products or alternative processes, new techniques or models, the planning and construction of prototypes or, in any case, costs borne for other scientific research activities or technological development, which do not satisfy conditions for the recognition in the balance sheet, are generally considered current costs and expensed as incurred.
Exchange rate differences
Revenues and costs concerning transactions in currencies other than the functional currency are stated at the exchange rate on the date that the transaction is completed.
Monetary assets and liabilities in currencies other than the functional currency are converted by applying the year end exchange rate and the effect is stated in the profit and loss account. Non-monetary assets and liabilities in currencies other than functional currency valued at cost are stated at the initial exchange rate; when they are evaluated at recoverable value or realizable value, the exchange rate applied is that of the day of recognition.
Dividends
Dividends are recognized at the date of the general shareholders’ meeting in which they were declared, except when the sale of shares before the ex-dividend date is certain.
Income taxes
Current income taxes are determined on the basis of estimated taxable income; the estimated liability is recognized in the item “Income tax liabilities”. Current tax assets and liabilities are measured at the amount expected to be paid to (recovered from) the tax authorities, using the tax rates (and tax laws) that have been enacted or substantively enacted at the balance sheet date.

(6) |  | For stock grants, the period between the date of the award and the date of assignation of stock; for stock options, the period between the date of the award and the date on which the option can be exercised.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Deferred tax assets or liabilities are provided on temporary differences arising between the carrying amounts of the assets and liabilities in the Financial Statements and their tax bases. Deferred tax assets are recognized when their realization is considered probable.
Deferred tax assets and liabilities are recorded under non-current assets and liabilities and are offset at a single entity level if related to offsettable taxes. The balance of the offset, if positive, is recognized in the item “Deferred tax assets”; if negative, in the item “Deferred tax liabilities”. When the results of transactions are recognized directly in the shareholders’ equity, current taxes, deferred tax assets and liabilities are also charged to the shareholders’ equity.
Derivatives
Derivatives, including embedded derivatives which are separated from the host contract, are assets and liabilities recognized at their fair value which is estimated by using the criteria described in the section “Current Assets”.
Derivatives are classified as hedging instruments when the relationship between the derivative and the subject of the hedge is formally documented and the effectiveness of the hedge is high and is checked periodically. When hedging instruments cover the risk of variation of the fair value of the hedged item (fair value hedge, e.g., hedging of the variability on the fair value of fixed interest rate assets/liabilities), the derivatives are stated at fair value and the effects charged to the profit and loss account. Hedged items are consistently adjusted to reflect the variability of fair value associated with the hedged risk. When derivatives hedge the cash flow variation risk of the hedged item (cash flow hedge, e.g., hedging the variability on the cash flows of assets/liabilities as a result of the fluctuations of exchange rate), changes in the fair value of the derivatives, considered effective, are initially stated in net equity and then recognized in the profit and loss account consistently with the economic effects produced by the hedged transaction. The changes in the fair value of derivatives that do not meet the conditions required to qualify as hedging instruments are shown in the profit and loss account.
Financial statements
Assets and liabilities of the balance sheet are classified as current and non-current. Items of the profit and loss account are presented by nature.
Statements of changes in shareholders' equity present profit and loss for the year and other changes of the shareholders' equity.
Statements of cash flows are presented using the indirect method, whereby net profit is adjusted for the effects of transactions of a non-cash nature.
Changes in accounting principles
Since 2006, Eni applies: (i) the requirements of IFRIC 4 “Determining whether an arrangement contains a lease” that provides guidance for determining whether arrangements that do not take the legal form of a lease but which convey rights to use assets in return for a payment or series of payments should be treated as a lease; (ii) the amendments to IAS 39 “Financial instruments: recognition and measurement” that are related to: (a) the possibility to qualify as hedging instruments, in relation to cash flow hedge operations on exchange rate risk realting to inter-company transactions expected and with a high probability, on condition that these transactions are denominated in a functional currency other than the currency of the entity that carries out the operation and the exposure to the exchange rate risk has a potential effect on consolidated profit and loss account; (b) the recognition and measurement of financial guarantees that are recorded when they are issued as a liability valued at market value and then, in relation to the execution risk, at the greater of the best estimate of the charge to be sustained to fulfill the obligation and the initial amount reduced by premiums collected; (iii) the requirements of IFRIC 5 “Rights to interests arising from decommissioning, restoration and environmental funds” that provide guidance for determining the recognition and measurement for the contribution to funds established to finance decommissioning that have the following features: (a) the assets are held and administered by a separate legal entity; and (b) contributor’s right to access the assets of the fund is restricted.
The contributor recognizes its obligation to pay separately decommissioning costs as a liability and its interest in the fund. In the case that the interest means having control, having joint control or significant influence over the fund, the entity contributor must recognize the interest in the fund as an investment in a subsidiary, associate or joint venture.
The adoption of these principles did not generate a material effect.

Use of accounting estimates
The preparation of these consolidated financial statements requires Management to apply accounting estimates that are based on complex or subjective judgments, estimates based on past experience and assumptions determined to be reasonable and realistic considering the information available at the date of the estimate. The application of these estimates and assumptions affects the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of income and expenses during the reporting period. Actual results may differ from these estimates given the uncertainty surrounding the assumptions and conditions upon which the estimates are based. Summarized below are the critical accounting estimates that require the more subjective judgment of our management. Such assumptions or estimates regard the effects of matters that are inherently uncertain and for which changes in conditions may significantly affect future results.
Oil and gas activities
Engineering estimates of the Company’s oil and gas reserves are inherently uncertain. Proved reserves are the estimated volumes of crude oil, natural gas and gas condensates, liquids and associated substances which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Although there are authoritative guidelines regarding the engineering criteria that must be met before estimated oil and gas reserves can be designated as “proved”, the accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgment.
Field reserves will only be categorized as proved when all the criteria for attribution of proved status have been met. At this stage, all booked reserves will be categorized as proved undeveloped. Volumes will subsequently be recategorized from proved undeveloped to proved developed as a consequence of development activity. The first proved developed bookings will occur at the point of first oil or gas production. Major development projects typically take one to four years from the time of initial booking to the start of production. Adjustments may be made to booked reserves due to production, reservoir performance, commercial factors, acquisition and divestment activity and additional reservoir development activity. In particular, changes in oil and natural gas prices could impact the amount of Eni’s proved reserves as regards the initial estimate and, in the case of Production Sharing Agreements and buy-back contracts, the share of production and reserves to which Eni is entitled. Accordingly, the estimated reserves could be materially different from the quantities of oil and natural gas that ultimately will be recovered.
Oil and natural gas reserves have a direct impact on certain amounts reported in the Financial Statements. Estimated proved reserves are used in determining depreciation and depletion expenses and impairment expense. Depreciation rates on oil and gas assets using the UOP basis are determined from the ratio between the amount of hydrocarbons extracted in the quarter and proved developed reserves existing at the end of the quarter increased by the amounts extracted during the quarter. Assuming all other variables are held constant, an increase in estimated proved developed reserves decreases depreciation, depletion and amortization expense. On the contrary, a decrease in estimated proved developed reserves increases depreciation, depletion and amortization expense. In addition, estimated proved reserves are used to calculate future cash flows from oil and gas properties, which serve as an indicator in determining whether a property impairment is to be carried out or not. The larger the volumes of estimated reserves, the less likely the property is impaired.
Impairment of Assets
Eni assesses its tangible and intangible assets, including goodwill, for possible impairment if there are events or changes in circumstances that indicate that the carrying values of the assets are not recoverable. Such indicators include changes in the Group’s business plans, changes in commodity prices leading to unprofitable performance and, for oil and gas properties, significant downward revisions of estimated proved reserve quantities. Determination as to whether and how much an asset is impaired involves management estimates on highly uncertain matters such as future commodity prices, the effects of inflation and technology improvements on operating expenses, production profiles and the outlook for global or regional market supply and demand conditions for crude oil, natural gas, commodity chemicals and refined products.
The amount of an impairment loss is determined by comparing the book value of an asset with its recoverable amount. The recoverable amount is the greater of fair value net of disposal costs and value in use. The estimated value in use is based on the present values of expected future cash flows net of disposal costs. The expected future cash flows used for impairment reviews are based on judgmental assessments of future production volumes, prices and costs, considering available information at the date of review and are discounted by using a rate related to the activity involved.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

For oil and natural gas properties, the expected future cash flows are estimated based on developed and non-developed proved reserves including, among other elements, production taxes and the costs to be incurred for the reserves yet to be developed. The estimated future level of production is based on assumptions on: future commodity prices, lifting and development costs, field decline rates, market demand and supply, economic regulatory climates and other factors.
Goodwill and other intangible assets with indefinite useful life are not amortized but they are checked at least annually to determine whether their carrying amount is recoverable and in any case, when trigger events arise that would lead the entity to assume the value of an asset is impaired. In particular, goodwill impairment is based on the determination of the fair value of each cash generating unit to which goodwill can be attributed on a reasonable and consistent basis. A cash generating unit is the smallest aggregate on which the company, directly or indirectly, evaluates the return on the capital expenditure. If the fair value of a cash generating unit is lower than the carrying amount, goodwill attributed to that cash generating unit is impaired up to that difference; if the carrying amount of goodwill is less than the amount of impairment, assets of the cash generating unit are impaired on a pro-rata basis for the residual difference.
Asset Retirement Obligations
Obligations related to the removal of tangible equipment and the restoration of land or seabeds require significant estimates in calculating the amount of the obligation and determining the amount required to be recorded in the Consolidated Financial Statements. Estimating future asset removal costs is difficult and requires management to make estimates and judgments due to the fact that most removal obligations will come to term many years into the future and contracts and regulations are often unclear as to what constitutes removal. Asset removal technologies and costs are constantly changing, as well as political, environmental, safety and public relations considerations. The subjectivity of these estimates is also increased by the accounting method used that requires entities to record the fair value of a liability for an asset retirement obligations in the period when it is incurred (typically, at the time, the asset is installed at the production location). When liabilities are initially recorded, the related fixed assets are increased by an equal corresponding amount. The liabilities are increased with the passage of time (interest accretion) and any change of the estimates following the modification of future cash flows and discount rate is adopted. The recognized asset retirement obligations are based upon future retirement cost estimates and incorporate many assumptions such as: expected recoverable quantities of crude oil and natural gas, abandonment time, future inflation rates and the risk-free rate of interest adjusted for the Company’s credit costs.
Business Combinations
Accounting for the acquisition of a business requires the allocation of the purchase price to most assets and liabilities acquired at fair value. Any positive residual difference is recognized as “Goodwill”. Negative residual differences are charged against the profit and loss account. Management uses all available information to make these fair value determinations and, for major business acquisitions, typically engages an independent appraisal firm to assist in the fair value determination of the acquired assets and liabilities.
Environmental Liabilities
Together with other companies in the industries in which it operates, Eni is subject to numerous EU, national, regional and local environmental laws and regulations concerning its oil and gas operations, productions and other activities, including legislation that implements international conventions or protocols. Environmental costs are recognized when it becomes probable that a liability has been incurred and the amount can be reasonably estimated.
Although management, considering the actions already taken, insurance policies to cover environmental risks and provision for risks accrued, does not expect any material adverse effect on Eni’s consolidated results of operations and financial position as a result of such laws and regulations, there can be no assurance that there will not be a material adverse impact on Eni’s consolidated results of operations and financial position due to: (i) the possibility of a yet unknown contamination; (ii) the results of the ongoing surveys and other possible effects of statements required by Decree No. 471/1999 of the Ministry of Environment concerning the remediation of contaminated sites; (iii) the possible effect of future environmental legislation and rules; (iv) the effect of possible technological changes relating to future remediation; and (v) the possibility of litigation and the difficulty of determining Eni’s liability, if any, as against other potentially responsible parties with respect to such litigation and the possible insurance recoveries.

Employees benefits
Defined benefit plans and other long term benefits are evaluated with reference to uncertain events and based upon actuarial assumptions including among others discount rates, expected rates of return on plan assets, expected rates of salary increases, medical cost trend rates, estimated retirement dates, mortality rates.
The significant assumptions used to account for pensions and other post-retirement benefits are determined as follows: (i) discount and inflation rates reflect the rates at which benefits could be effectively settled, taking into account the duration of the obligation. Indications used in selecting the discount rate include rates of annuity contracts and rates of return on high quality fixed-income investments (such as government bonds). The inflation rates reflect market conditions observed country by country; (ii) the future salary levels of the individual employees are determined including an estimate of future changes attributed to general price levels (consistent with inflation rate assumptions), productivity, seniority and promotion; (iii) healthcare cost trend assumptions reflect an estimate of the actual future changes in the cost of the healthcare related benefits provided to the plan participants and are based on past and current healthcare cost trends including healthcare inflation, changes in healthcare utilization and changes in health status of the participants; (iv) demographic assumptions such as mortality, disability and turnover reflect the best estimate of these future events for the individual employees involved, based principally on available actuarial data; (v) determination of expected rates of return on assets is made through compound averaging. For each plan, the distribution of investments among bonds, equities and cash and their specific average expected rate of return is taken into account. Differences between expected and actual costs and between the expected return and the actual return on plan assets routinely occur and are called actuarial gains and losses.
Eni applies the corridor method to amortize its actuarial losses and gains. This method amortizes on a pro-rata basis the net cumulative actuarial gains and losses, unrecognized at the end of the previous reporting period, that exceed 10% of the greater of (i) the present value of the defined benefit obligation and (ii) the fair value of plan assets, over the average expected remaining working lives of the employees participating in the plan.
Additionally, obligations for other long term benefits are determined by adopting actuarial assumptions; the effect of changes in actuarial assumptions or a change in the characteristics of the benefit are taken to profit or loss in their entirety.
Contingencies
In addition to accruing the estimated costs for environmental liabilities, asset retirement obligations and employees benefits, Eni accrues for all contingencies that are both probable and estimable. These other contingencies are primarily related to litigation and tax issues. Determining appropriate amounts for accrual is a complex estimation process that includes subjective judgments.
Revenue recognition in the Engineering & Construction segment
Revenue recognition in the Engineering & Construction business segment is based on the stage of completion of a contract as measured on the cost-to-cost basis applied to contractual revenues. Use of the stage of completion method requires estimates of future gross profit on a contract by contract basis. The future gross profit represents the profit remaining after deducting costs attributable to the contract from revenues provided for in the contract. The estimate of future gross profit is based on a complex estimation process, that includes identification of risks related to geographical region, market conditions in that region and any assessment that it is necessary to estimate with sufficient precision the total future costs as well as the expected timetable. Requests of additional incomes, deriving from a change in the scope of the work, are included in the total amount of revenues when it is probable that the customer will approve the variation and the related amount; claims deriving for instance from additional costs incurred for reasons attributable to the client are included in the total amount of revenues when it is probable that the counterpart will accept them.

Recent accounting principles
With Regulation No. 108/2006 issued on January 11, 2006 the European Commission approved IFRS 7 “Financial instruments: disclosures”. IFRS 7 establishes the disclosures to be provided regarding financial instruments and the exposure and management of financial risks. The requirements of IFRS 7 include some disclosures currently required by IAS 32 “Financial instruments: exposures and additional disclosures”. IFRS 7 went into effect on January 1, 2007.
Eni is presently analyzing this statements and, at the moment, cannot determine if adoption of this tandard will have a significant effect on Eni’s Consolidated Financial Statements.

Concessions, licenses, trademarks and similar items for euro 856 million primarily concern the transport rights for natural gas imported from Algeria (euro 572 million) and concessions for mineral exploration (euro 223 million).

Other intangible assets |  |  |  |  | 4 |  | - | 25 |

The gross carrying amount of fully depreciated intangible assets still in use amount to euro 767 million.
Other changes of intangible assets with a definite life of euro 29 million include negative exchange rate differences due to the translation of financial statements prepared in currencies other than the euro of euro 28 million.
Goodwill for euro 2,084 million concerns essentially the Engineering & Construction segment (euro 828 million, of which euro 805 million relates to the purchase of Bouygues Offshore SA, now Saipem SA), the Gas & Power segment (euro 982 million, of which euro 757 million relates to the public offering of Italgas SpA shares in 2003), the Exploration & Production segment (euro 225 million, of which euro 220 million relates to the purchase of Lasmo Plc, now Eni Lasmo Plc) and the Refining & Marketing segment (euro 46 million).
In order to determine the recoverable amount, goodwill related to the acquisition of Bouygues Offshore SA and Italgas SpA has been allocated to the following cash generating units:

(million euro) |  | Dec. 31, 2006

Bouygues Offshore SA |  |  |
Offshore constructions |  | 403 |
Onshore constructions |  | 165 |
LNG |  | 159 |
MMO - Maintenance Modification and Operation |  | 78 |
|  | 805 |
Italgas SpA |  |  |
Domestic gas market |  | 706 |
Foreign gas market |  | 51 |
|  | 757 |

The recoverable amount of cash generating units is determined based on expected cash flows estimated using the market assumptions of Eni’s 2007-2010 Strategic Plan and discounted at rates included between 4.7% and 14.3%. For the years not included in the strategic market assumptions, Eni has used an incremental rate included between 0% and 2%. Key assumptions are based on past experience and take into account the current level of interest rates.
Other changes related to goodwill of euro 170 million concern the allocation to goodwill of the difference between the price paid by Snam Rete Gas SpA and Saipem SpA for the purchase of treasury shares and the corresponding portion of shareholders’ equity acquired following the increase of Eni’s interest (euro 171 million) and the change in scope of consolidation related to the acquisition of 50% of Siciliana Gas SpA (euro 23 million). Such increase was partially offset by the decrease in the impairment of goodwill allocated to Tigaz Zrt following its acquisition by Italgas SpA (euro 46 million). The impairment of goodwill allocated to Tigaz Zrt was made following the application of the new Hungarian tariff regime, in force from 2006, and was determined on the basis of the new estimate of future cash flows, discounted by using a rate of 6.3%.

21 Provisions for employee benefits
Provisions for employee benefits of euro 1,071 million (euro 1,031 million at December 31, 2005) consist of the following:

(million euro) |  | Dec. 31, 2005 |  | Dec. 31, 2006

TFR |  | 577 |  | 608
Pensions plans |  | 318 |  | 268
Supplementary medical reserve for Eni managers (FISDE) |  | 99 |  | 100
Other benefits |  | 37 |  | 95
|  | 1,031 |  | 1,071

Provisions for indemnities upon termination of employment essentially concern the provisions accrued by Italian companies for employee termination indemnities ("TFR"), regulated by Article 2120 of the Italian Civil Code. The indemnity is paid out as capital and is determined by the total of the provisions set aside, calculated in consideration of the employee’s compensation during the service period, and revalued until retirement. Provisions to TFR, considered for the determination of liabilities and costs, are net of the amounts paid to pension funds.
Effective from January 1, 2007 the Budget Law for 2007 and related decrees introduce material changes to the TFR regulation; these changes include the possibility for employees to choose the allocation of their TFR entitlement between a pension fund or having it remain in the company (in which case the company will transfer the future TFR obligation to INPS, the Italian state social security entity). At present there are uncertainties in interpretation regarding the recent changes in regulations. Furthermore, there is additional uncertainty arising from the revised regulations in respect to actuarial calculations on already accrued TFR provisions since it is currently not possible to predict employees’ choices regarding their allocation of the TFR entitlement (employees’ choice shall be made before June 30, 2007). Given this level of uncertainty, there has been no change made, which may result from the new regulations, to the amount of the TFR obligation recorded as at December 31, 2006.
Pension funds concern defined benefit plans of foreign companies located, primarily, in the United Kingdom, Nigeria and Germany. Benefits consist of a return on capital determined on the basis of the length of service and the compensation paid in the last year of service or an average annual compensation paid in a determined period preceding the retirement.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The supplementary medical reserve for Eni managers (FISDE) is calculated on the basis of the contributions paid by the company for retired managers.
Other benefits primarily concern Jubilee awards and the deferred monetary incentive plan. Jubilee awards are benefits due following the attainment of a minimum period of service and, for the Italian companies, consist of an in-kind remuneration. Deferred monetary incentive plan reflects the estimate of the variable compensation dependent on the Company’s performance that will be paid in 2009 to Eni managers who reach individual defined objectives.

Commitments and contingencies
Commitments and contingencies of euro 1,545 million (euro 1,655 million at December 31, 2005) consist of the following:

(million euro) |  | Dec. 31, 2005 |  | Dec. 31, 2006

Commitments |  |  |  |
Purchase of assets |  | 219 |  | 9

|  | 439 |  | 216

|  | 1,655 |  | 1,545

Obligations for purchase and sales of assets of euro 9 million decreased by euro 210 million. Such decrease was due to: (i) the extinguishment of the placement on the market of securities managed by Sofid Sim SpA. This company sold Italian Government bonds to investors and simultaneously entered into interest rate swaps with such investors wherein it received the rate of interest on such Italian Government bonds and paid a floating rate of interest linked to Euribor. Such investors could sell their securities back to Sofid Sim SpA at any time at par value plus related interest with the simultaneous cancellation of the related swaps (euro 116 million). The operation ended on January 1, 2006 following the expiry of the government bonds; (ii) to the acquisition from ESPI - Ente Siciliano per la Promozione Industriale (in liquidation) of 50% of the capital share of Siciliana Gas SpA and 1 share of Siciliana Gas Vendite SpA (euro 98 million).
Other commitments of euro 207 million (euro 220 million at December 31, 2005) are essentially related to a memorandum of intent signed with the Basilicata Region, whereby Eni has agreed to invest, also on account of Shell Italia E&P SpA, euro 181 million in the future in connection with Eni’s development plan of oil fields in Val d’Agri (euro 193 million at December 31, 2005).
Risks of euro 1,329 million (euro 1,216 million at December 31, 2005) primarily concern potential risks associated with the value of assets of third parties under the custody of Eni for euro 918 million (euro 794 million at December 31, 2005) and contractual assurances given to acquirors of certain investments and businesses of Eni for euro 393 million (euro 402 million at December 31, 2005).

Risk management

FOREWORD
The main risks identified and managed by Eni are the following:
(i) market risks deriving from the exposure to the fluctuations of interest rates, exchange rates between the euro and the US dollar and other currencies used by the company, as well as the volatility of commodity prices;
(ii) the credit risk deriving from the possible default of a counterparty;
(iii) the liquidity risk deriving from the risk that suitable sources of funding for the Group’s business activities may not be available;
(iv) country risk in oil & gas activities;
(v) the operation risk deriving from the occurrence of accidents, malfunctioning, failures with damage to persons and the environment affecting operating and financial results.

MARKET RISK
Market risk is the possibility that changes in currency exchange rates, interest rates or oil, natural gas and power prices will adversely affect the value of the group’s financial assets, liabilities or expected future cash flows. Their management follows a set of guidelines and procedures that concentrate the treasury function in two captive finance companies operating in the Italian and international financial markets. In particular, the finance company operating on the domestic market (Enifin) manages all the transactions concerning currencies and derivative financial contracts. Commodity risk is managed by each business unit while Enifin manages the negotiation of hedging derivatives. Starting on January 1, 2007, this task is being performed by Eni SpA following the incorporation of Enifin.
In order to minimize market risks related to changes in interest rates and exchange rates and to manage exposure to commodity prices fluctuations, Eni enters into various transactions using derivative financial instruments (derivatives). Derivatives are contracts whose value is derived from one or more underlying financial instrument, index or price that are defined in the contract. The group also trades derivatives in conjunction with these risk management activities. Eni does not enter into derivative transactions on a speculative basis.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The control framework defined by Eni’ s guidelines prescribes that measurement and control of the market risk are to be performed on the basis of maximum acceptable levels of risk exposure defined in accordance with value-at-risk techniques. These techniques make a statistical assessment of the market risk, i.e., potential gain or loss in fair values.
Eni’s guidelines prescribe that Eni’s subsidiaries use such market risk exposure policies as to minimize market risk. Tolerable market risk exposure is set at the Group level within the central finance department which pools all risk positions of the Group. Calculation and measurement techniques followed by Eni are in accordance with established banking standards (such standards are established by the Basel Committee). However, the tolerable level of risk adopted by Eni is more conservative than the recommended one.
Eni’s guidelines prescribe that the exposure to risk from fluctuations in commodity prices is to be managed in a way as to maximize the value of the Group oil and gas production and sales volumes and to pursue set objectives of industrial margins. Risk exposure within trading activities is defined within maximum levels of value-at-risk attributed at each business unit, with the central function managing hedging request. Strategic risk exposure is monitored in terms of value-at-risk, albeit being not hedged in a systematic way.

EXCHANGE RATE RISK
Exchange rate risk derives from the fact that Eni’s operations are conducted in currencies other than the euro (in particular the US dollar) and with the time lag existing between the recording of costs and revenues denominated in currencies other than the functional currency and the actual time of the relevant monetary transaction (transaction exchange rate risk). Generally speaking, an appreciation of the US dollar versus the euro generally has a positive impact on Eni’s results of operations, and vice versa. Effective management of exchange rate risk is performed at the Group level, within the central finance department which matches contrarian positions of the Group operating subsidiaries and hedges net positions using derivatives (such as currency swaps, forwards and options). Such derivatives are recognized at fair value on the basis of market prices provided from specialized sources. Value-at-risk deriving from currency exposure is measured daily on the basis of a variance/covariance model, with a 99% confidence level and a 20-day holding period. The transaction currency risk on certain strategic holdings is deemed to be immaterial.

INTEREST RATE RISK
Variations in interest rates affect the market value of financial assets and liabilities of the company and the level of financial changes. Eni uses interest rate derivatives; such interest rate swaps and interest cross currency swaps are used to effectively manage the balance between fixed and floating rate debt. Such derivatives are recognized at fair value on the basis of market prices provided from specialized sources. Value-at-risk deriving from interest rate exposure is measured daily on the basis of a variance/covariance model, with a 99% confidence level and a 20-day holding period.

COMMODITY RISK
Eni’s results of operations are affected by changes in the prices of commodities. A decrease in oil, gas and product prices generally has a negative impact on Eni’s results of operations, and vice versa. In order to hedge commodity risk, Eni uses derivatives traded on the organized markets of ICE and NYMEX (futures and options) and derivatives traded over-the-counter (swaps, forwards and contracts for differences, with the underlying commodities being crude oil, refined products or electricity). Such derivatives are recognized at fair value on the basis of market prices provided from specialized sources or absent market prices, on the basis of estimates provided by brokers or suitable evaluation techniques. Value-at-risk deriving from commodity exposure is measured daily on the basis of a historical simulation technique, with a 95% confidence level and a one-day holding period.

CREDIT RISK
Credit risk is the potential exposure of the Group to loss in the event of non-performance by a counterparty. The credit risk arising from the Group’s normal commercial operations is controlled by individual operating units within Group-approved guidelines. The monitoring activity of credit risk exposure is performed at the Group level according to set guidelines and measurement techniques. In particular credit risk exposure to large clients and multi-business clients is monitored at the Group level on the basis of score cards quantifying risk levels. Eni’s guidelines define the characteristics of persons eligible to be counterparty of Eni in derivative contracts and cash management transactions. Eni constantly updates a list of eligible persons that includes highly credit-rated institutions. Eni has not experienced material non-performance by any counterparty. As of December 31, 2005 and December 31, 2006, Eni has no significant concentrations at credit risk.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

LIQUIDITY RISK
Liquidity risk is the risk that suitable sources of funding for the Group’s business activities may not be available. The group has long-term debt ratings of AA and Aa2, assigned respectively by Standard & Poor’s and Moody’s. The group has access to a wide range of funding at competitive rates through capital markets and banks and coordinates relationships with banks, borrowing requirements, foreign exchange requirements and cash management centrally.
At present, the Group believes it has access to sufficient funding and has also both committed and uncommitted borrowing facilities to meet currently foreseeable borrowing requirements.
Effective management of the liquidity risk has the objective of ensuring the availability of adequate funding to meet short term requirements and due obligations as well as the objective of ensuring a sufficient level of flexibility in order to fund the development plans of the Group’s businesses. This implies the adoption of a strategy to pursue an adequate structure of borrowing facilities (particularly the availability of committed borrowings facilities) and the maintenance of cash reserves.

COUNTRY RISK
Substantial portions of Eni’s hydrocarbons reserves are located in countries outside the EU and North America, certain of which may be politically or economically less stable than EU or North American countries. At December 31, 2006, approximately 70% of Eni’s proved hydrocarbons reserves were located in such countries. Similarly, a substantial portion of Eni’s natural gas supplies comes from countries outside the EU and North America. In 2006, approximately 60% of Eni’s domestic supply of natural gas came from such countries. Negative developments in the economic and political framework of these countries can temporarily or permanently compromise Eni’s ability to operate economically and to gain access to oil and natural gas reserves.
Eni constantly monitors the political, social and economic risk of the approximately 60 countries where it has invested or intends to invest with special attention to the evaluation of upstream investments. Country risks are mitigated by means of appropriate guidelines for risk management that Eni defined in its procedure for project risk assessment and management.

OPERATION RISK
The broad scope of Eni’s activities involves a wide range of operational risks such as those of explosion, fire or leakage of toxic products, and production of non biodegradable waste. All these events could possibly damage or even destroy plants, facilities, equipment and other property, cause injury or even death to persons or cause environmental damage.
Eni adopted the most stringent guidelines for the evaluation and management of health, safety and environmental (HSE) risks, with the objective of protecting Eni’s employees, contractors and clients, the populations involved in its activity, the environment and being in compliance with local and international rules and regulations. Eni’s guidelines prescribe the adoption of international best practices in setting internal principles, standards and solutions. An ongoing process for identifying, evaluating and managing HSE risks is at the heart of HSE operations in each phase of the business activity and is performed through the adoption of procedures tailored to the peculiarities of each business and industrial site.
HSE risks are effectively managed through an integrated management system designed along the principles set in Eni’s Model of HSE operations. This is a general procedure to be applied in all its operating sites, based on an annual cycle of planning, implementation, control, review of results and definition of new objectives. The model is directed towards the prevention of risks and a systematic monitoring and control of HSE performance in a continuous improvement cycle that is also subject to audits by internal and independent experts. Any environmental emergency is managed by business units locally with their own organization under preset reaction plans to foreseeable events aimed at limiting damage and at activating adequate responses.
Eni has two emergency rooms (in Milan and Rome) furnished with real time monitoring systems for the collection of data on georeferenced maps for all Eni sites and logistics worldwide. Meteorological equipment is in place to assess dimension, temporal development and other consequences of certain catastrophic events and to enable a real-time planning of first-aid interventions to help mitigate consequences. In addition to its own emergency teams, Eni entered international agreements in order to maximize its ability to react in all its operating sites.

Legal Proceedings

Eni is a party to a number of civil actions and administrative proceedings arising in the ordinary course of business. Based on information available to date, and taking the existing risk provisions into account, Eni believes that the foregoing will not have an adverse effect on Eni’s Consolidated Financial Statements.
The following is a description of the most significant proceedings currently pending; unless otherwise indicated below, no provisions have been made for these legal proceedings as Eni believes that negative outcomes are not probable or because the amount of the provision can not be estimated reliably.

1. Environment

1.1 Criminal Proceedings

ENI SPA

(i) |  | Subsidence. In relation to the investigations concerning a subsidence phenomenon allegedly caused by hydrocarbon exploration and extraction activities, following the decision of the Court of Rovigo, the Nucleo Operativo Ecologico dei Carabinieri of Venice placed under preliminary seizure the Naomi/Pandora field and producing platform in 2002 and the Dosso degli Angeli field in 2004. Eni believes it has always acted in full compliance with existing laws under the required authorizations. Taking into account the observations of the consultants of the Court of Rovigo on which the public prosecutor based his case, Eni constituted an independent and interdisciplinary scientific commission, composed of prominent and highly qualified international experts of subsidence caused by hydrocarbon exploration and extraction activities, with the aim of verifying the size and effects and any appropriate actions to reduce or to neutralize any subsidence phenomenon in the Ravenna and North Adriatic area both on land and in the sea. This commission produced a study which denies the possibility for any risk for human health and for damage to the environment. It also states that no example is known anywhere in the world of accidents that caused harm to the public safety caused by subsidence induced by hydrocarbon production. The study also shows that Eni employs the most advanced techniques for the monitoring, measuring and control of the soil. This proceeding is in the first level hearing stage. The Veneto Region, the Ente Parco della Provincia del Po, the Province of Ferrara, the Province of Venice, the City of Venice, the City of Comacchio, the Province of Rovigo and two private entities have been acting as plaintiffs. Eni was accepted as a defendant in order to claim its own civil responsibilities. Parties are awaiting a decision from the Italian Supreme Court as to whether this proceeding has to take place before the Court of Rovigo or the Court of Adria.
(ii) |  | Alleged damage. In 2002, the public prosecutor of Gela started a criminal investigation in order to ascertain alleged damage caused by emissions of the Gela plant, owned by Polimeri Europa SpA, Syndial SpA (former EniChem SpA) and Raffineria di Gela SpA.
(iii) |  | Negligent fire in the refinery of Gela. In June 2002, in connection with a fire at the refinery of Gela, a criminal investigation began concerning negligent fire, environmental crimes and crimes against natural beauty.
(iv) |  | Investigation of the quality of ground water in the area of the refinery of Gela. In 2002, the public prosecutor of Gela started a criminal investigation concerning the refinery of Gela to ascertain the quality of ground water in the area of the refinery. Eni is charged of having breached environmental rules concerning the pollution of water and soil and of illegal disposal of liquid and solid waste materials.
(v) |  | Intentional poisoning (Priolo). In March 2002, the public prosecutor of Siracusa started an investigation concerning the activity of the refinery of Priolo in order to ascertain whether infiltrations of refinery products into the deep water-bearing stratum used for human consumption purposes in the Priolo area had occurred. The Court entrusted a company specialized in such field with the task of verifying the cause, origin and extension of the alleged infiltration. For protective purposes, remedial actions have been taken in order to: (i) create safety measures and clean-up of the polluted area; (ii) reallocate wells for drinking water in an area farther from and higher than the industrial site; and (iii) install a purification system for drinkable water. These actions are moving towards completion.
(vi) |  | Negligent fire (Priolo). The public prosecutor of Siracusa started an investigation against certain Eni managers who were previously in charge of conducting operations at the Priolo refinery (Eni divested this asset in 2002) in order to ascertain whether they acted with negligence in connection with a fire that occurred at the Priolo plants on April 30 and May 1-2, 2006. Preliminary investigations have almost been completed.

ENIPOWER SPA

(i) |  | Unauthorized waste management activities. In 2004 the public prosecutor of Rovigo started an investigation for alleged crimes related to unauthorized waste management activities in Loreo relating to the samples of soil used during the construction of the new EniPower power station in Mantova. The prosecutor requested the CEO of EniPower and the managing director of the Mantova plant at the time of the alleged crime to stand trial.
(ii) |  | Air emissions. The Prosecutor of Mantova started an investigation against two managers of the Mantova plant in connection with air emissions by the new power plant.

POLIMERI EUROPA SPA
Violation of environmental regulations on waste management. Before the Court of Gela a criminal action took place relating to the alleged violation of environmental regulations on waste management concerning the ACN plant and the disposal of FOK residue deriving from the steam cracking process. Defendants were found guilty and a damage payment in first instance to an environmental association acting as plaintiff was required to be made. The amount of said damage payment is immaterial. The sentence was passed to the Civil Court for the quantification of any further damage and claim. Eni appealed the Court’s sentence.

RAFFINERIA DI GELA SPA
Soil and sea pollution. In 1999, the public prosecutor of Gela started an investigation in order to ascertain alleged soil and sea pollution caused by the discharge of pollutants by Eni’s Gela refinery. Three environmental organizations are acting as plaintiffs and have requested damage payment for euro 551 million. With a decision of February 20, 2007, the Court of Gela dismissed these allegations.

SYNDIAL SPA (FORMER ENICHEM SPA)
Criminal action started by the public prosecutor of Brindisi. In 2000, the public prosecutor of Brindisi started a criminal action against 68 persons who are employees or former employees of companies that owned and managed plants for the manufacture of dichloroethane, vinyl chloride monomer and vinyl polychloride from the early 1960s to date, some of which were managed by EniChem from 1983 to 1993. At the end of the preliminary investigation, the public prosecutor asked for the dismissal of the case in respect of the employees and the managers of EniChem. Plaintiffs presented oppositions and the prosecutor confirmed his request for dismissal of the case, rejecting such oppositions.

1.2 Civil and administrative proceedings

(i) |  | Pollution caused by the activity of the Mantova plant. In 1992, the Ministry of Environment summoned EniChem SpA and Montecatini SpA before the Court of Brescia. The Ministry requested, primarily, environmental remediation for the alleged pollution caused by the activity of the Mantova plant from 1976 until 1990, and provisionally, in case there was no possibility to remediate, the payment of environmental damages. EniChem acquired the Mantova plant in June 1989, as part of the Enimont deal. Parties agreed upon that Edison SpA would hold Eni harmless or pay compensatory damage for any damage caused to third parties by plant operations before Montedison’s sale, even if damage would manifests itself later. Parties agreed on a settlement by which Edison quantified the damage to be paid that also covers Syndial. The proceeding continues for the settlement of alleged damage pertaining to the residual 1989-1990 period.
(ii) |  | Summon before the Court of Venice for environmental damages caused to the lagoon of Venice by the Porto Marghera plants. On December 13, 2002, EniChem SpA, jointly with Ambiente SpA (now merged into Syndial SpA) and European Vinyls Corporation Italia SpA, was summoned before the Court of Venice by the Province of Venice. The province requested compensation for environmental damages that were not quantified, caused to the lagoon of Venice by the Porto Marghera plants, which were already the subject of two previous criminal proceedings against employees and managers of the defendants. In a related action, European Vinyls Corporation Italia presented an action for recourse against EniChem and Ambiente. Parties are waiting for the decision on the instances of the preliminary investigation.
(iii) |  | Claim of environmental damages, caused by industrial activities in the area of Crotone, commenced by the President of the Regional Council of Calabria. On April 14, 2003, the President of the Regional Council of Calabria, as Delegated Commissioner for Environmental Emergency in the Calabria Region, started an action against EniChem SpA related to environmental damages for approximately euro 129 million and damages for euro 250 million (plus interest and compensation) in connection with loss of income and damage to property allegedly caused by Pertusola Sud SpA activities (merged into EniChem) in the area of Crotone. In addition, the Province of Crotone is acting as plaintiff, claiming environmental damages for euro 300 million. The judge has yet to decide on the legitimacy of the Delegated Commissioner for Environmental Emergency in the Calabria Region to act on behalf of the Calabria Region. On October 21, 2004, Syndial was convened before the Court of Milan by the Calabria Region which is seeking to obtain a condemnation of Syndial for a damage payment, should the office of the Delegated Commissioner for Environmental Emergency in the Calabria Region cease during this proceeding. The Calabria Region requested damage payment amounting to euro 800 million as already requested by the Delegated Commissioner for environmental emergency in the Calabria Region in the proceeding started in 2003. This new proceeding is in the preliminary investigation stage. On February 28, 2006, the Council of Ministers, Ministry for the Environment and Delegated Commissioner for environmental emergency in the Calabria Region represented by the State Lawyer requested Syndial to appear before the Court of Milan in order to obtain the ascertainment, quantification and payment of damage (in the form of land, air and water pollution and therefore of

|  | the general condition of the population) caused by the operations of Pertusola Sud SpA in the Municipality of Crotone and in surrounding municipalities. The local authorities requested the ascertainment of Syndial’s responsibility as concerns expenses borne and to be borne for the cleanup and reclamation of sites, currently quantified at euro 129 million. This proceeding concerns the same matter and damage claim as the proceedings started by the Delegated Commissioner for environmental emergency in the Calabria Region and the Calabria Region against Syndial in 2003 and 2004, respectively.
(iv) |  | Summon for the ascertainment of responsibility in the pollution of soil at Paderno Dugnano. In 2004, Sitindustrie SpA, which in 1996 purchased a plant in Paderno Dugnano from Enirisorse (now merged into Syndial SpA), summoned Syndial SpA before the Court of Milan, requesting to establish the Syndial SpA’s responsibility in the alleged pollution of soil around the plant and to require it to pay environmental damage necessary for remediation. The Tribunal of Milan rejected the plaintiff’s request with a sentence released on June 10, 2006. The deadline to appeal the Tribunal sentence is November 1, 2007.
(v) |  | Summon for the ascertainment of responsibility in the pollution of soil at Pieve Vergonte. In October 2004, Sitindustrie SpA commenced an analogous proceeding against Syndial concerning the plant for the manufacture of products in copper and copper alloy in Pieve Vergonte.
(vi) |  | Summon for environmental damage caused by DDT pollution in Lake Maggiore. A proceeding is pending before the Court of Turin by which the Minister of the Environment summoned Syndial SpA and requested environmental damage for euro 2,396 million in relation to alleged DDT pollution of Lake Maggiore caused by the Pieve Vergonte plant. On March 1, 2006, the State Lawyer in an attempt to settle the case proposed Syndial to pay 10% of this claim corresponding to euro 239 million. This settlement attempt failed. The Italian Ministry enacted a ministerial decree providing for the: (i) upgrading of a hydraulic barrier to protect the site; (ii) presentation of a project for the environmental remediation of Lake Maggiore. Syndial opposed this decree before an Administrative Court.
(vii) |  | Action started by the Municipality of Carrara for the remediation and reestablishment of previous environmental conditions at the Avenza site and payment of the environmental damage. The Municipality of Carrara started an action before the Court of Genova requesting Syndial SpA to remediate and reestablish previous environmental conditions at the Avenza site and the payment of certain environmental damage which cannot be cleaned up plus further damage of various genre (i.e., damage to the natural beauty of this site). This request is related to an accident that occurred in 1984, as a consequence of which EniChem Agricoltura SpA (later merged into Syndial SpA), at the time owner of the site, carried out safety and remediation works. The Ministry of the Environment joined the action and requested environmental damage payment – from a minimum of euro 53.5 million to a maximum of euro 93.3 million – to be broken down among the various companies that ran the plant in the past. In fact, Syndial summoned Rumianca SpA, Sir Finanziaria SpA and Sogemo SpA, who ran the plant in previous years, in order to be guaranteed. A report made by an independent expert charged by the Judge was filed with the Court. The findings of this report quantify the residual environmental damage at euro 15 million. A final decision on this proceeding is pending.
(viii) |  | Ministry for the Environment - Augusta harbor. The Italian Ministry for the Environment with variuos administrative acts ordered companies running plants in the petrochemical site of Priolo to perform safety and environmental remediation works in the Augusta harbor. Companies involved include Eni subsidiaries Polimeri Europa and Syndial. Pollution has been detected in this area primarily due to a high mercury concentration which is allegedly attributed to the industrial activity of the Priolo petrochemical site. Polimeri Europa opposed said administrative acts, objecting in particular the way by which remediation works have been designed and information on concentration of pollutants have been gathered.

2. Other judicial or arbitration proceedings

SYNDIAL SPA (FORMER ENICHEM SPA)

(i) |  | Serfactoring: disposal of receivables. In 1991, Agrifactoring SpA commenced proceedings against Serfactoring SpA, a company 49% owned by Sofid SpA which is controlled by Eni SpA. The claim relates to an amount receivable of euro 182 million for fertilizer sales (plus interest and compensation for inflation), originally owed by Federconsorzi to EniChem Agricoltura SpA (later Agricoltura SpA - in liquidation), and Terni Industrie Chimiche SpA (merged into Agricoltura SpA - in liquidation), that has been merged into EniChem SpA (now Syndial SpA). Such receivables were transferred by Agricoltura and Terni Industrie Chimiche to Serfactoring, which appointed Agrifactoring as its agent to collect payments. Agrifactoring guaranteed to pay the amount of such receivables to Serfactoring, regardless of whether or not it received payment on the due date. Following payment by Agrifactoring to Serfactoring, Agrifactoring was placed in liquidation and the liquidator of Agrifactoring commenced proceedings in 1991 against Serfactoring to recover such payments (equal to euro 182 million) made to Serfactoring based on the claim that the foregoing guarantee became invalid when Federconsorzi was itself placed in

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

|  | liquidation. Agricoltura and Terni Industrie Chimiche brought counterclaims against Agrifactoring (in liquidation) for damages amounting to euro 97 million relating to acts carried out by Agrifactoring SpA as agent. The amount of these counterclaims has subsequently been reduced to euro 46 million following partial payment of the original receivables by the liquidator of Federconsorzi and various setoffs. These proceedings, which have all been joined, were decided with a partial judgment, deposited on February 24, 2004; the request of Agrifactoring has been rejected and the company has been ordered to pay the sum requested by Serfactoring and damages in favor of Agricoltura, to be determined following the decision. Agrifactoring appealed this partial decision, requesting in particular the annulment of the first step judgment, the reimbursement of euro 180 million from Serfactoring along with the rejection of all its claims and the payment of all proceeding expenses. The hearing of the pending appeal was set for March 16, 2007 but was rescheduled to October 27, 2007 upon request of Agrifactoring. The judge of the Court of Rome, responsible for the determination of the amount of damages to be paid to Serfactoring and Agricoltura decided on May 18, 2005 to suspend this determination until the publication of the decision of the Court of Appeals. On argument, Serfactoring and Syndial requested that the Court of Cassation cancel the suspension and return the case to its original court.
(ii) |  | Breach of a preliminary agreement for the purchase of an industrial area in Ravenna. In 2002, EniChem SpA was summoned by ICR Intermedi Chimici di Ravenna Srl before the Court of Milan in relation to a breach of a preliminary agreement for the purchase of an industrial area in Ravenna. ICR requested payment of compensatory damage for approximately euro 46 million, of which euro 3 million are compensatory damage and euro 43 million are for loss of income. With a sentence of October 11, 2005, the Court rejected ICR’s request and ordered that ICR pay all proceeding expenses. ICR filed a claim against this decision, reducing its original claim to euro 8 million. A final decision is pending.

3. Antitrust, EU Proceedings, Actions of the Italian Authority for Electricity and Gas and of Other Regulatory Authorities

3.1 Antitrust

ENI SPA

(i) |  | Abuse of dominant position of Snam verified by the AGCM. In March 1999, the Italian Antitrust Authority ("AGCM") concluded its investigation started in 1997 and: (i) verified that Snam SpA (merged in Eni SpA in 2002) abused its dominant position in the market for the transportation and primary distribution of natural gas relating to the transportation and distribution tariffs applied to third parties and the access of third parties to infrastructure; (ii) fined Snam euro 2 million; and (iii) ordered a review of these practices relating to such abuses. Snam believes it has complied with existing legislation and appealed the decision with the Regional Administrative Court of Lazio requesting its suspension. On May 26, 1999, stating that these decisions are against Law No. 9/1991 and the European Directive 98/30/EC, this Court granted the suspension of the decision. The Authority did not appeal this decision. The decision on the merit of this dispute is still pending before the same Administrative Court.
(ii) |  | Inquiry of the AGCM on jet fuel. With a decision of December 9, 2004, the Italian Antitrust Authority commenced an inquiry on the distribution of jet fuel against six oil companies operating in Italy, including Eni and certain entities jointly controlled by said oil companies engaged in the storing and loading of jet fuel in the Rome Fiumicino, Milan Linate and Milan Malpensa airports. The inquiry intends to ascertain the existence of alleged restrictions to competition as said oil companies would agree to divide among themselves the supplies to airlines. On December 22, 2005, the Authority notified the preliminary results of the inquiry concerning: (i) information flows to said oil companies related to the functioning of the jointly-controlled entities engaging in the storage and uploading of jet fuel; (ii) barriers to the entrance of new competitors in the capital of such entities operating the activities of storing and loading; and (iii) the price of jet fuel which is deemed to be higher than on other European markets. On June 20, 2006, the Authority notified the final decision of this proceeding to Eni and fined Eni by an amount of euro 117 million. The Authority fined other oil companies involved in this matter. Eni filed an opposition against this decision before an administrative court and suspended the payment of this fine. On January 29, 2007, the Regional Administrative Court of Lazio accepted only partially the opposition made by Eni and annulled part of the decision of the Authority. In particular, a measure providing for the involved oil companies to cease their joint participation in the capital of the entities operating the activities of storing and loading jet fuel was annulled. Eni accrued a provision with respect to this proceeding.
(iii) |  | Formal assessment started by the Commission of the European Communities for the evaluation of alleged participation to activities limiting competition in the field of paraffin. On April 28, 2005, the Commission of the European Communities started a formal assessment to evaluate the alleged participation of Eni and its subsidiaries to

|  | activities limiting competition in the field of paraffin. The alleged violation of competition would have consisted in: (i) the determination of and increase in prices; (ii) the subdivision of customers; and (iii) exchange of trade secrets, such as production capacity and sales volumes. Subsequently, the Commission requested information on Eni’s activities in the field of paraffins and certain documentation acquired by the Commission during an inspection. Eni filed the requested information.
(iv) |  | Notification to Eni Petroleum Co Inc of a subpoena by the Department of Justice of the United States of America - Antitrust Division and request of information and documents relating to activities in the field of wax and of a deposition. On April 28, 2005, the Department of Justice of the United States of America - Antitrust Division, notified Eni Petroleum Co Inc of a subpoena requesting information and documents relating to activities in the field of wax to be filed before June 20, 2005 and a deposition on the same date. The Company informed the department that it does not produce nor import wax in the United States of America.
(v) |  | Inquiry started by the AGCM concerning an alleged abuse of dominant position in the use of the total continuous regasification capacity of GNL. On November 18, 2005, the Italian Antitrust Authority notified Eni and its subsidiary GNL Italia the opening of an inquiry, in accordance with Article 14 of Law No. 287/1990, concerning an alleged abuse of dominant position in the assignment and use of the total continuous regasification capacity of the Panigaglia terminal (owned by GNL Italia) during thermal years 2002-2003 and 2003-2004, as already reported by an inquiry of the Italian Authority for Electricity and Gas on the same matter as the inquiry of the Antitrust Authority. The Authority for Electricity and Gas closed its inquiry by signalling the fact to the Antitrust Authority. In a later communication Eni was informed that the inquiry has been extended also to thermal year 2004-2005 and to Snam Rete Gas which is the parent company of GNL Italia SpA. On September 25, 2006, the Antitrust Authority sent Eni the findings of its inquiry. Subsequently, Eni presented the Antitrust Authority certain commitments based on Article 14-ter of Law No. 287/1990. On November 23, 2006, the Antitrust Authority resolved to publish such commitments effective the following day. On March 6, 2007, the Antitrust Authority resolved to accept Eni’s commitments and to close the inquiry without recognizing any charge to Eni and imposing any fine whatsoever. Eni is committed to perform a gas release amounting to 4 billion cubic meters in a two-year period, starting on October 1, 2007.
(vi) |  | Ascertainment by the European Commission of the level of competition in the European natural gas market. As part of its activities to ascertain the level of competition in the European natural gas market, with decision No. C(2006)1920/1 of May 5, 2006, the European Commission informed Eni on May 16, 2006 that Eni and its subsidiaries were subject to an inquiry under Article 20, paragraph 4 of the European Regulation No. 1/2003 of the Council in order to verify the possible existence of any business conducts breaching European rules in terms of competition and intended to prevent access to the Italian natural gas wholesale market and to subdivide the market among few operators in the activity of supply and transport of natural gas. Officials from the European Commission conducted inspections at headquarters of Eni and of certain Eni subsidiaries and collected documents. Similar actions have been performed by the Commission also against the main operators in natural gas in Germany, France, Austria and Belgium.
(vii) |  | TTPC. In April 2006, Eni filed a claim before the Regional Administrative Court of Lazio against the decision of the Italian Antitrust Authority of February 15, 2006 stating that Eni’s behaviour pertaining to implementations of plans for the upgrading of the TTPC pipeline for importing natural gas from Algeria represented an abuse of dominant position under Article 82 of the European Treaty and fined Eni. The initial fine amounted to euro 390 million and was reduced to euro 290 million in consideration of Eni’s commitment to perform actions favoring competition among which the upgrading of said gasline. Eni accrued a provision with respect to this proceeding. With a decision filed on November 29, 2006, the Regional Administrative Court of Lazio partially accepted Eni’s claim, annulling such part of the Authority’s decision where the fine was quantified. Eni is waiting for the filing of the motivations of the Court decision to ascertain the impact of said decision. Pending this development, the payment of the fine has been voluntarily suspended.
(viii) |  | Inquiry of the AGCM in relation to collusive mechanisms for the pricing of automotive fuels distributed on the retail market. With a decision of January 18, 2007, the Italian Antitrust Authority opened an inquiry to ascertain the existence of a possible agreement to limit competition in the field of pricing of automotive fuels distributed on the retail market in Italy in violation of Article 81 of the EC Treaty. This inquiry concerns eight oil companies, among which Eni. According to the Authority, said companies would have been putting in place collusive mechanisms intended to influence the pricing of automotive fuels distributed on the retail market by way of a continuing exchange of informative flows since 2004.With decision of January 18, 2007, the Italian Antitrust Authority opened an inquiry to ascertain the existence of a possible agreement limit competition in the field of pricing of automotive fuels distributed on the retail market in Italy in violation of Article 81 of the EC Treaty.

In December 2002, inquiries were commenced concerning alleged anti-competitive agreements in the area of elastomers. These inquiries were commenced concurrently by European and U.S. authorities. The first product under scrutiny was EP(D)M: the European Commission submitted to inspection the manufacturing companies of that product, among which Polimeri Europa SpA and Syndial and requested information from those two companies and to their parent company, Eni SpA. After the inquiries the Commission decided to open a procedure for violation of competition laws and notified Eni, Polimeri Europa and Syndial the relevant charges to that effect on March 8, 2005. At a hearing held on July 27, 2005 the two companies presented memoranda and confirmed their position. Eni and its subsidiaries are waiting for a decision on part of the European Commission.
EP(D)M manufacture is also under scrutiny in the United States, where the Department of Justice of San Francisco requested information and documents to Polimeri Europa Americas Inc, a U.S. subsidiary of Polimeri Europa and to its deputy chairman and sales manager. Class actions were filed claiming damages in relation to the alleged violation. On July 2005, Syndial signed a settlement agreement for the civil class action which entails the payment of approximately $3.2 million, approved by the federal court. The investigation was also extended to the following products: NBR, CR, BR, SSBR and SBR. The European Commission started an investigation regarding BR, SBR, SSBR. On January 26, 2005, the European Commission dropped the charges in relation to SSBR. Investigations regarding BR, SBR and EPDM led to the notification of relevant charges. A hearing took place before the European Commission. On July 26, 2006, the European Commission notified the dismissal of the EPDM matter to Eni. Regarding the other two products BR and SBR, on November 29, 2006, the Commission fined a number of European operators, among which Eni, an amount of euro 519 million based on the charge of having established a trust in the field of synthetic rubber production. Eni and its subsidiary Polimeri Europa were fined by an overall amount of euro 272.25 million. Eni and its subsidiary are preparing an appeal against this decision claiming in particular the existence of the infringing behavior and the amount of the fine, and the fact that Eni is accountable for the behavior of its subsidiaries.
With regard to NBR, an inquiry is underway in Europe and the U.S., where class actions have also been started. On the federal level, the class action was abandoned by the plaintiffs. The federal judge has yet to acknowledge this abandonment. With regard to CR, as part of an investigation carried out in the U.S., Syndial entered into a plea agreement with the Department of Justice pursuant to which Syndial would agree to pay a fine of $9 million, while the Department of Justice would agree that it will not bring further criminal charges against Syndial or against its affiliated companies. On June 27, 2005 the plea agreement was approved. As regards CR, the civil class action was closed with a settlement agreement approved by the federal judge on July 8, 2005 whereby the company will pay $5 million.
Eni recorded a provision for these matters.

3.2 Regulation

Inquiry of the Italian Authority for Electricity and Gas regarding the use of storage capacity conferred in years 2004-2005 and 2005-2006. With Decision No. 37 of February 23, 2006, the Italian Authority for Electricity and Gas commenced an inquiry on a few natural gas selling companies, among which Eni, in order to possibly impose a fine or an administrative sanction regarding the use of storage capacity conferred in years 2004-2005 and 2005-2006.
For the 2004-2005 thermal year and for the period from October 1, 2005 to December 31, 2005, the Authority for Electricity and Gas supposed that given the weather of the period, the use of modulation storage capacity was featured by a higher volume of off takes with respect to the volume which would have been necessary to satisfy the commercial requirements for which the storage company entitled Eni to a priority in the conferral of storage capacity. According to the Authority for Electricity and Gas, such situation was in contrast with applicable regulation.
Eni presented an articulated and documented memorandum to claim the thesis of the Authority for Electricity and Gas regarding the alleged non compliance of Eni's behavior with regulation in force, also taking account of the circumstances under which excess off takes occurred and the subsequent authorization of the Ministry for Economic Development to use the strategic storage for the thermal year 2004-2005. With Decision No. 281/2006 of December 6, 2006, the Authority for Electricity and Gas closed said inquiry and fined Eni by euro 90 million of which euro 45 million pertaining to the thermal year 2004-2005 and euro 45 million to the thermal year 2005-2006 as a consequence of Eni having violated regulation in force pertaining to the priorities in the conferral of storage capacity.
Eni plans to pay the amount of this fine pertaining to the thermal year 2004-2005 in accordance to a reduced form as provided by Law No. 689/1981and to appeal Decision No. 281/2006 of the Authority for Electricity and Gas before the Regional Administrative Court of Lombardia requesting the Tribunal: (i) for the first thermal year, to ascertain whether Eni is legitimate to pay in a reduced form or, in case Eni is not legitimate to do so, to annul the fine; (ii) for the second thermal year, to annul the fine. Eni accrued a provision for this proceeding.

STOCCAGGI GAS ITALIA SPA
Tariffs. With Decision No. 26 of February 27, 2002, the Italian Authority for Electricity and Gas determined tariff criteria for modulation, mineral and strategic storage services for the period from April 1, 2002 to March 31, 2006 and effective retroactively from June 21, 2000. On March 18, 2002 Stoccaggi Gas Italia SpA (Stogit) filed its proposal of tariff for modulation, mineral and strategic storage for the first regulated period. With Decision No. 49 of March 26, 2002, the Authority for Electricity and Gas repealed Stogit’s proposal and defined tariffs for the first regulated period. Stogit applied the tariff determined by the two decisions, but filed an appeal against both decisions with the Regional Administrative Court of Lombardia requesting their cancellation. With a decision dated September 29, 2003, that court rejected the appeal presented by Stogit. Stogit filed an appeal to the Council of State against the sentence which was rejected by the Council of State on January 6, 2006.

DISTRIBUIDORA DE GAS CUYANA SA
Formal investigation of the agency entrusted with the regulation of the natural gas market in Argentina ("Enargas"). The agency entrusted with the regulation of the natural gas market in Argentina ("Enargas") started a formal investigation on some operators, among these Distribuidora de Gas Cuyana SA, a company controlled by Eni. Enargas stated that the company improperly applied calculated conversion factors to volumes of natural gas invoiced to customers and requested the company to apply the conversion factors imposed by local regulations from the date of the default notification (March 31, 2004) without prejudice to any damage payment and fines that may be decided after closing the investigation. On April 27, 2004, Distribuidora de Gas Cuyana presented a defense memorandum to Enargas, without prejudice to any possible appeal. On April 28, 2006, the Company filed a formal request for examining the documents used as evidence of the alleged violation.

4. Tax Proceedings

ENI SPA
With a decree dated December 6, 2000, the Lombardia Region decided that natural gas used for electricity generation is subject to an additional regional excise tax in relation to which Snam SpA (merged into Eni SpA in 2002) should substitute for the tax authorities in its collection from customers. Given interpretive uncertainties, the same decree provides the terms within which distributing companies are expected to pay this excise tax without paying any penalty. Snam SpA and the other distributing companies of Eni believe that natural gas used for electricity generation is not subject to this additional excise tax. For this reason, an official interpretation was requested from the Ministry of Finance and Economy. With a decision of May 29, 2001, the Ministry confirmed that this additional excise tax cannot be applied. The Region decided not to revoke its decree and Snam took appropriate legal action. On the basis of action carried out by Snam, the Council of State decided on March 18, 2002 that the jurisdiction of the Administrative court did not apply to this case. In case the Region should request payment, Eni will challenge this request in the relevant Court. The Lombardia Region decided with regional Law No. 27/2001 that no additional tax is due from January 1, 2002 onwards, but still requested the payment of taxes due before that date. The action for the recognition of such taxes bears a five-year term. Consequently, the exercise of such action expires on July 16, 2007.
With a formal assessment presented by the Municipality of Pineto (Teramo), Eni SpA has been accused of not having paid a municipal tax on real estate for the period from 1993 to 1998 on four oil platforms located in the Adriatic Sea territorial waters in front of the coast of Pineto. Eni was requested to pay a total of approximately euro 17 million including interest and a fine for lacking payment and tax declaration. Eni filed a claim against this request stating that the sea where the platforms are located is not part of the municipal territory and the tax application as requested by the municipality lacked objective fundamentals. The claim has been accepted in the first two degrees of judgment at the Provincial and Regional Tax Commissions. But the Court of Cassation cancelled both judgments declaring that a municipality can consider requesting a tax on real estate also in the sea facing its territory and with a decision of February 21, 2005 sent the proceeding to another section of the Regional Tax Commission in order to judge on the other reasons opposed by Eni. On December 28, 2005, the Municipality of Pineto presented the same request for the same platforms for the years 1999 to 2004. The total amount requested from Eni is euro 24 million. Eni filed a claim against this request.

SNAM RETE GAS SPA
Environmental tax of the Sicilia Region upon the owners of primary pipelines. With Regional Law No. 2 of March 26, 2002, the Sicilia Region introduced an environmental tax upon the owners of primary pipelines in Sicily (i.e., pipelines operating at a maximum pressure of over 24 bar). The tax was payable as of April 2002. In order

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

to protect its interests, Snam Rete Gas filed a claim with the European Commission, aimed at opening a proceeding against the Italian Government and the Tax Commission of Palermo. The Authority for Electricity and Gas, although acknowledging that the tax burden is an operating cost for the transport activity, subjected inclusion of the environment tax in tariffs to the final ruling on its legitimacy by relevant authorities. With the ruling of December 20, 2002, the Court judged the tax at variance with European rules. In December 2002, Snam Rete Gas suspended payments based on the above Court ruling. Payments effected until November 2002 totaled euro 86.1 million. In January 2003, the Sicilia Region filed an appeal with the Council of State against the ruling of the Regional Administrative Court of Lombardia for the part that states the variance of the regional law with European rules. On December 16, 2003, the European Commission judged the tax instituted by the Republic of Italy, through the Sicilia Region, to be contrary to European rules and to the cooperation agreement between the European Economic Community and the Peoples’ Democratic Republic of Algeria; the European Commission also stated that such environmental tax is in contrast with the common customs tariff because it modifies the equality of customs expenses on commodities imported from third countries and could create a deviation in trade with such countries and a distortion in access and competition rules. The Commission with its opinion presented on July 7, 2004 formally requested Italy to cancel the tax. The Italian Government was ordered to conform within two months from receipt of the opinion. As it did not conform, on December 20, 2004 the European Commission passed the case to the Court of Justice requesting a ruling. With a decision dated January 5, 2004, and confirmed on March 4, 2005 by the Regional Tax Commission, the Provincial Tax Commission of Palermo declared the environmental tax of the Sicilia Region illegitimate because it is contrary to European rules and therefore accepted Snam Rete Gas’s claim for the repayment of the first installment of euro 10.8 million, already paid to the Sicilia Region in April 2002. On May 4, 2004, the Sicilia Region repaid the first installment. As for the seven remaining installments paid after April 2002 (euro 75.3 million), the Provincial Tax Commission of Palermo with decision of January 5, 2005 confirmed the illegitimacy of the tax condemning the Region to repay the cashed amounts and accrued interest to Snam Rete Gas. The Sicilia Region presented recourse against said decision before the Regional Tax Commission at Palermo on April 15, 2005. The relevant hearing was held on April 5, 2006. On January 17, 2007, decisions were filed pertaining to four out of seven recourses presented by the Sicilia Region; each of said recourses corresponds to an installment of the tax paid by Snam Rete Gas. Said decisions rejected the recourses presented by the Sicilia Region. Snam Rete Gas expects similar developments with regard to residual recourses.

AGIP KARACHAGANAK BV
Claims concerning unpaid taxes and relevant payment of interest and penalties. In July 2004, relevant Kazakh authorities informed Agip Karachaganak BV and Agip Karachaganak Petroleum Operating BV, shareholder and operator of the Karachaganak contract, respectively, on the final outcome of the tax audits performed for fiscal years 2000 to 2003. Claims by the Kazakh authorities concern unpaid taxes for a total of $43 million, net to Eni, and the anticipated offsetting of VAT credits for $140 million, net to Eni, as well as the payment of interest and penalties for a total of $128 million. Both companies filed a counterclaim. With an agreement reached on November 18, 2004, the original amounts were reduced to $26 million net to Eni that includes taxes, surcharges and interest. Meetings continue regarding residual matters. Eni recorded a provision for this matter.

5. Settled Proceedings

RAFFINERIA DI GELA SPA
With a sentence released in July 2006, the Court of Gela ascertained that certain alleged crimes pertaining to the emissions of the refinery had become extinct due to the statute of limitations. In relation to such alleged crimes, the Court of Gela summoned the legal representatives of the company for events that have occurred since 1997. The Municipality of Gela, the Province of Caltanissetta and others acted as plaintiff in this proceeding, requesting the payment of compensatory damages for a total of euro 878 million.

SYNDIAL SPA
Personal cautionary measures against some employees of the Priolo plant issued by the Court of Siracusa concerning illicit management relating to waste activities. On January 16, 2003, the Court of Siracusa issued personal cautionary measures against several employees of the Priolo plant owned by EniChem SpA and Polimeri Europa SpA, within judicial investigations pertaining to an illicit management relating to the production, disposal and treatment of liquid and solid waste materials resulting in an illicit income from the savings arising from the non compliance with rules regulating waste activities. Polimeri Europa and EniChem acted as plaintiffs. Findings of the preliminary investigations were notified to involved persons, confirming accusations. During the

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

preliminary investigations, traces of mercury were found in the sea. The public prosecutor of Siracusa started an inquiry for ascertaining the conditions of sediments and marine fauna in the bay of Augusta. According to the prosecutor, mercury was spilled into the sea and poisoned the marine fauna and therefore resulted in fetal malformations and abortions due to the consumption of contaminated seafood fished in this area. The chlorine soda plant, built in the late 1950s was contributed in-kind to Syndial in 1989 when the Enimont joint venture was formed. It was therefore proved that Eni’s employees held no responsibility for the crimes of which they were charged. On March 15, 2006, the judge for preliminary investigations decided the dismissal of the case against Syndial employees, accepting the request made by the prosecutor.

SYNDIAL SPA (FORMER ENICHEM SPA)
In 1997, an action was commenced before the Court of Venice concerning the criminal charges brought by the Venice public prosecutor for alleged mismanagement of the Porto Marghera plant starting in the 1970s until 1995 and for the alleged pollution and health damage resulting there from. Defendants included certain employees of Eni which have managed the Porto Marghera plant since the beginning of the eighties. On November 2, 2001, the Court of Venice acquitted all defendants. The appeal against the decision was presented by the public prosecutor, the state attorney on behalf of the Ministry of Environment and the Council of Ministers, five public entities, 12 associations and other entities and 48 individual persons. On December 15, 2004 the Venice Court of Appeals confirmed the preceding judgment, changing only some marginal parts. As concerns some defendants, the Venice Court of Appeals decided not to proceed due to the statute of limitations for some crimes, while it confirmed the preceding judgment for the other matters. On May 19, 2006, the Court of Final Instance, before which plaintiffs appealed the decision of the Venice Court of Appeals, acquitted all defendants stating that pollution and mismanagement of the plant occurred before the 1980s and consequently Eni and its employees could not be deemed responsible. In January 2006, Eni settled this matter with the Council of Ministers and the Ministry for the Environment paying an amount of euro 40 million. Under terms of the settlement, the latter will abstain from recourse to the Court of Final Instance and will not act on any other environmental damage concerning the management of Porto Marghera until the date of the settlement. Eni already recorded a provision for this matter which was sufficient to cover the amount of the settlement.

ENI DACIÓN BV
In August 2005, the internal revenue service of Venezuela served four formal assessment on income taxes to Eni Dación BV for the years 2001 to 2004 that, by excluding the deductibility of certain costs: (i) annul the losses recorded for the periods amounting to a total of bolivar 910 billion (corresponding to $425 million); (ii) determine for the same periods a taxable income amounting to a total of bolivar 115 billion (corresponding to $54 million); and (iii) request a tax amounting to bolivar 52 billion (corresponding to $24 million) determined by applying a 50% tax rate rather than the 34% rate applied to other companies performing activities analogous to those of Eni Dación BV. In particular, it excluded the deductibility of: (i) interest charges due to other Eni Group companies that provided loans denominated in U.S. dollars; and (ii) exchange rate losses recorded in the financial statements and related to such loans resulting from the devaluation of the Venezuelan currency. The formal assessments served have a preliminary nature and do not request immediate payment nor do they specify the amount of a fine (from 10 to 250%) and of interest (average rate for the period approximately 23%). Eni Dación filed a claim for the cancellation of the assessment. In the 2005 accounts, Eni recorded a specific provision for this matter. In April 2006, the appeal was rejected and the final tax assessment was issued. The final tax assessment: (i) substantially confirmed the preliminary assessments, although reducing the originally assessed income tax liability to bolivar 39 billion ($18 million); and (ii) imposed fines and late payment interests of bolivar 109 billion ($51 million). Eni Dación BV presented a further administrative appeal before the expiration of the time limit for filing a judicial tax appeal, thereby obtaining a reduction of the overall amount from bolivar 148 billion ($69 million) to bolivar 52 billion ($24 million) including taxes in the amount of bolivar 12.5 billion ($6 million) and fines and late payment interest in the amount of bolivar 39.5 billion ($18 million). In order to avoid further charges deriving from the increase of the corresponding fines and late payment interest, Eni Dación BV paid the newly assessed amount in May 2006, thereby reaching a settlement. Consistently, Eni Dación BV filed an integrative income tax return for year 2005, considering the new tax bases for years 2001 to 2004, and paid accordingly bolivar 128 billion ($60 million) of income taxes and bolivar 4.4 billion ($2 million) of fines and late payment interest.

Other risks and commitments
In order to meet the medium and long-term demand of natural gas, in particular in the Italian market, Eni entered into long-term purchase contracts with producing countries. Specifically, following the strategic agreement with Gazprom signed on November 14, 2006, effective from February 1, 2007, Eni extended the duration of its gas supply contracts with Gazprom until 2035, bringing the residual average life of its supply portfolio to approximately 23 years. Existing contracts, which in general contain take-or-pay clauses, will ensure a total of approximately 62.4 bcm/y of natural gas by 2010.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Despite the fact that an increasing portion of natural gas volumes purchased under such contracts has been sold outside Italy, management believes that in the long term, unfavorable trends in the Italian demand and supply for natural gas, also due to the possible implementation of all publicy announced plans for the construction of new supply infrastructure, and the evolution of Italian regulations of the natural gas sector, represent risk factors to the fullfilment of Eni's obligations in connection with its take-or-pay supply contracts.
Parent company guarantees given relating to contractual commitments for hydrocarbon exploration and production activities, quantified on the basis of the capital expenditures to be made, amount to euro 4,911 million (euro 5,052 million at December 31, 2005).
With effective date April 1, 2006, the Venezuelan State oil company Petróleos de Venezuela SA (PDVSA) unilaterally terminated the Operating Service Agreement (OSA) governing activities at the Dación oil field where Eni acted as a contractor, holding a 100% working interest. As a consequence, starting on the same day, operations at the Dación oil field are conducted by PDVSA. Eni proposed to PDVSA to agree on terms in order to recover the fair value of its Dación assets. On November 2006, Eni commenced proceeding before an International Centre for Settlement of Investment Disputes (ICSID) Tribunal (i.e., a tribunal acting under the auspices of the ICSID Convention and being competent pursuant to the Treaty) to claim its rights. In fact, a bilateral investments treaty is in place between The Netherlands and Venezuela (the "Treaty"). Despite this action, Eni is still ready to negotiate a solution with PDVSA to obtain a fair compensation for its assets. Based on the opinion of its legal consultants, Eni believes to be entitled to a compensation for such expropriation in an amount equal to the market value of the OSA before the expropriation took place. The market value of the OSA depends upon its expected profits. In accordance with established international practice, Eni has calculated the OSA’s market value using the discounted cash flow method, based on Eni’s interest in the expected future hydrocarbon production and associated capital expenditures and operating costs, and applying to the projected cash flow a discount rate reflecting Eni’s cost of capital as well as the specific risk of concerned activities. Independent evaluations carried out by a primary petroleum consulting firm fully support Eni’s internal evaluation. The estimated net present value of Eni’s interest in the Dación field, as calculated by Eni, is higher than the net book value of the Dación assets amounting to $829 million (equal to euro 629 million based on the EUR/US$ exchange rate as of December 31, 2006) which consequently have not been impaired. In accordance with the ICSID Convention, a judgement by the ICSID Tribunal awarding compensation to Eni would be binding upon the parties and immediately enforceable as if it were a final judgement of a court of each of the States that have ratified the ICSID Convention. The ICSID Convention was ratified in 143 States. Accordingly, if Venezuela fails to comply with the award and to pay the compensation, Eni could take steps to enforce the award against commercial assets of the Venezuelan Government almost anywhere those may be located (subject to national law provisions on sovereign immunity). In 2005 and 2006, oil production from the Dación field averaged approximately 60 kbbl/d and booked reserves at December 31, 2005 amounted to 175 million of barrels.
Under the convention signed on October 15, 1991 by TAV SpA and CEPAV Due, Eni committed to guarantee the execution of design and construction of the works assigned to the CEPAV Consortium (to which it is a party) and guaranteed to TAV the correct and timely execution of all obligations indicated in the convention in a subsequent integration deed and in any further addendum or change or integration to the same. The regulation of CEPAV Due contains the same obligations and guarantees contained in the CEPAV Uno agreement.
A guarantee for euro 253 million to Cameron LNG provided on behalf of Eni USA Gas Marketing Llc (Eni Petroleum Co Inc’s interest 100%) for the regasification contract entered into on August 1, 2005. This guarantee is subject to a suspension clause and will come into force when the regasification service starts in a period included between October 1, 2008 and June 30, 2009.
Non-quantifiable risks related to contractual assurances given to acquirers of investments against certain unforeseeable liabilities attributable to tax, state welfare contributions and environmental matters applicable to periods during which such investments were owned by Eni. Eni believes such matters will not have a material adverse effect on its Consolidated Financial Statements.

Assets under concession arrangements
Eni operates under concession arrangements mainly in the Exploration & Production segment and in some activities of the Gas & Power segment and the Refining & Marketing segment. In the Exploration & Production segment contractual clauses governing mineral concessions, licenses and exploration permits regulate the access of Eni to hydrocarbon reserves. Such clauses can differ in each country. In particular, mineral concessions, licenses and permits are granted by the legal owners and, generally, entered into with government entities, State oil companies and, in some legal contexts, private owners. As a compensation for mineral concessions, Eni pays royalties and taxes in accordance with local tax legislation. Eni sustains all the operation risks and costs related to the production and development activities and is entitled to the productions realized. In Product Sharing Agreements and in buy-back contracts, realized productions are defined on the basis of contractual agreements drawn up with State oil companies which hold the concessions. Such contractual agreements regulate the recovery of costs incurred for the exploration, development and operating activities (cost oil) and give entitlement to the own portion of the realized productions (profit oil). With reference to natural gas storage in Italy, the activity is conducted on the basis of concessions with a duration that

192

##### Contents

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

does not exceed a twenty years length and it is granted by the Ministry of Productive Activities to subjects that comply with legislation requirements and that can demonstrate to be able to conduct a storage program that meets the public interest in accordance with applicable laws. In the Gas & Power segment the gas distribution activity is primarily conducted on the basis of concessions granted by local public entities. At the expiry date of the concession, a compensation is provided, defined by using criteria of business appraisal, to the outgoing operator following the sale of its own gas distribution network. Service tariffs for distribution are defined on the basis of a method established by the Authority for Electricity and Gas. Legislative Decree No. 164/2000 provides the granting of distribution services exclusively by tender, with a maximum lenght of 12 years. In the Refining & Marketing segment several service stations and other auxiliary assets of the distribution service are located in the motorway areas and they are granted by the motorway concession operators following a public tender for the sub-concession of the supplying of oil products distribution service and other auxiliary services. Such assets are amortized over the length of the concession (generally, 5 years for Italy). In exchange of the granting of the services described above, Eni provides to the motorway companies fixed and variable royalties on the basis of quantities sold. At the end of the concession period, the uncharged devolution of non-removable assets is generally provided.

Environmental regulations
Together with other companies in the industries in which it operates, Eni is subject to numerous EU, national, regional and local environmental laws and regulations concerning its oil and gas operations, products and other activities, including legislation that implements international conventions or protocols. In particular, these laws and regulations require the acquisition of a permit before drilling for hydrocarbons may commence, restrict the types, quantities and concentration of various substances that can be released into the environment in connection with exploration, drilling and production activities, limit or prohibit drilling activities on certain protected areas, and impose criminal or civil liabilities for pollution resulting from oil, natural gas, refining and petrochemical operations. These laws and regulations may also restrict emissions and discharges to surface and subsurface water resulting from the operation of natural gas processing plants, petrochemicals plants, refineries, pipeline systems and other facilities that Eni owns. In addition, Eni’s operations are subject to laws and regulations relating to the generation, handling, transportation, storage, disposal and treatment of waste materials. Environmental laws and regulations have a substantial impact on Eni’s operations. Some risk of environmental costs and liabilities is inherent in particular operations and products of Eni, as it is with other companies engaged in similar businesses, and there can be no assurance that material costs and liabilities will not be incurred. Although management, considering the actions already taken with the insurance policies to cover environmental risks and the provision for risks accrued, does not currently expect any material adverse effect upon Eni’s consolidated financial statements as a result of its compliance with such laws and regulations, there can be no assurance that there will not be a material adverse impact on Eni’s consolidated financial statements due to: (i) the possibility of as yet unknown contamination; (ii) the results of the ongoing surveys and the other possible effects of statements required by Decree No. 471/1999 of the Ministry of the Environment; (iii) the possible effect of future environmental legislation and rules; (iv) the effect of possible technological changes relating to future remediation; (v) the possibility of litigation and the difficulty of determining Eni’s liability, if any, as against other potentially responsible parties with respect to such litigation and the possible insurance recoveries.

Emission trading
Legislative Decree No. 216 of April 4, 2006 implemented the Emission Trading Directive 2003/87/EC concerning greenhouse gas emissions and Directive 2004/101/EC concerning the use of carbon credits deriving from projects for the reduction of emissions based on the flexible mechanisms devised by the Kyoto Protocol. This European emission trading scheme has been in force since January 1, 2005, and on this matter, on February 24, 2006, the Ministry of the Environment published a decree defining emission permits for the 2005-2007 period. In particular, Eni was assigned permits corresponding to 65.2 million tonnes of carbon dioxide (of which 22.4 for 2005, 21.4 for 2006 and 21.4 for 2007). Following the realization of projects for the reduction of emissions, in particular related to the cogeneration of electricity and steam through high efficiency combined cycles in refineries and petrochemical sites, emissions of carbon dioxide from Eni’s plants were lower than permits assigned in 2006.

2002-2004 AND 2005 PLANS
Stock options provide the right to purchase treasury shares with a 1 to 1 ratio after the end of the third year from the date ofthe grant (vesting period) and for a maximum period of five years, with a price calculated as the arithmetic average of official prices registered on the Mercato Telematico Azionario in the month preceding assignment or (starting from 2003), if greater, as the average cost of treasury shares registered in the day preceding the assignment (strike price).

2006-2008 PLAN
The 2006-2008 stock option plan introduced a performance condition for the exercise of the options. At the end of each three-year period (vesting period) from the assignment, the Board of Directors will determine a number of exercisable options, at a rate included between 0 and 100, in relation to the Total Shareholders’ Return (TSR) of Eni’s shares compared to the TSR of the six largest international oil companies for capitalization. Options can be exercised after three years from the date of the grant (vesting period) and for a maximum period of three years, with a price calculated as the arithmetic average of official prices registered on the Mercato Telematico Azionario in the month preceding the assignment (strike price).
The arithmetic average of such prices, weighted with the number of shares assigned, amounts to euro 23.119 per share.

At December 31, 2006, a total of 15,290,400 options were offered for the purchase of 15,290,400 Eni SpA ordinary shares at a nominal value of euro 1.

Income (expense) on derivatives consist of the following:

(million euro) |  | 2005 |  | 2006

Derivatives on exchange rate |  | (85 | ) |  | 313 |
Derivatives on interest rate |  | (138 | ) |  | 61 |
Derivatives on commodities |  | (163 | ) |  | 9 |
|  | (386 | ) |  | 383 |

The increase in income (expense) from derivatives of euro 769 million is primarily due to the application of IAS 39 which requires that derivatives be stated at fair value and the effects charged to the profit and loss account, instead of being connected with the economic effects of the hedged transactions. Such derivatives, in fact, do not meet the conditions required by IFRS to be qualified as hedging instruments. In addition, the decrease in net exchange differences of euro 321 million is primarily due to the application of IAS 39, due to the fact that the effect of the translation at period end of assets and liabilities denominated in currencies other than the functional currency is not compensated by the effect of the translation at period end of the commitments for derivatives contracts.

30 Income tax expense
Income tax expense consists of the following:

(million euro) |  | 2005 |  | 2006

Current taxes: |  |  |  |  |  |
- Italian subsidiaries |  | 1,872 |  |  | 2,007 |
- foreign subsidiaries of the Exploration & Production segment |  | 5,116 |  |  | 6,740 |
- foreign subsidiaries |  | 373 |  |  | 529 |
|  | 7,361 |  |  | 9,276 |
Less: |  |  |  |  |  |
- tax credits on dividend distributions not offset with current tax payment |  | (34 | ) |  |  |
|  | 7,327 |  |  | 9,276 |
Net deferred taxes: |  |  |  |  |  |
- Italian subsidiaries |  | 334 |  |  | 230 |
- foreign subsidiaries of the Exploration & Production segment |  | 464 |  |  | 1,095 |
- foreign subsidiaries |  | 3 |  |  | (33 | )
|  | 801 |  |  | 1,292 |
|  | 8,128 |  |  | 10,568 |

Current taxes of the year relate to Italian companies for euro 2,007 million and concern Ires for euro 1,570 and Irap for euro 374 million and foreign taxes for euro 63 million.
The effective tax rate was 51.8% (46.8% in 2005) compared with a statutory tax rate of 37.9% calculated by applying a 33% tax rate (Ires) to profit before income taxes and 4.25% tax rate (Irap) to the net value of production as provided for by Italian laws.
The difference between the statutory and effective tax rate is due to the following factors:

(%) |  | 2005 |  | 2006

Statutory tax rate |  | 38.1 |  |  | 37.9 |
Items increasing (decreasing) statutory tax rate: |  |  |  |  |  |
- higher foreign subsidiaries tax rate |  | 8.8 |  |  | 13.6 |
- permanent differences |  | 0.8 |  |  | 0.2 |
- other |  | (0.9 | ) |  | 0.1 |
|  | 8.7 |  |  | 13.9 |
|  | 46.8 |  |  | 51.8 |

The increase in the tax rate of foreign subsidiaries of 4.8% essentially concerns the Eploration & Production segment (4.5%) and includes the effects deriving from the application of the windfall tax introduced by the Algerian government effective from August 1, 2006 (1.6%), a supplemental tax rate introduced by the government of the United Kingdom relating to the North Sea production effective from January 1, 2006 (1.0%) and the increase and the different allocation by country of profit before income taxes (1.9%).
Permanent differences in 2006 mainly concern the nondeductibility from taxable income of costs relating to fines of the Italian Antitrust Authority (0.4%).
Permanent differences in 2005 mainly concern the nondeductibility from taxable income of the increase in provisions for contingencies following the fine imposed on February 15, 2006 by the Italian Antitrust Authority to Eni SpA (0.6%).
31 Earnings per share
Basic earnings per share is calculated by dividing "Net profit" of the year by the weighted-average number of shares issued and outstanding during the year, excluding treasury shares.
The average number of shares used for the calculation of the basic earnings per share was 3,758,519,603 and 3,698,201,896 in 2005 and 2006, respectively.
Diluted earnings per share is calculated by dividing "Net profit" of the year by the weighted-average number of shares issued and outstanding during the year, excluding treasury shares, including shares that could be issued potentially.
At December 31, 2005 and December 31, 2006, shares that could be issued potentially concern essentially shares granted under stock grant and stock option plans. The average number of shares used for the calculation of the diluted earnings per share was 3,763,375,140 and 3,701,262,557 in 2005 and 2006, respectively.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

36 Adjustment of the Consolidated Financial Statements to U.S. GAAP
As its shares are listed on the New York Stock Exchange, Eni files an Annual Report (Form 20-F) with the Securities and Exchange Commission (SEC). The Annual Report (Form 20-F) includes the adjustment of the Consolidated Financial Statements to U.S. GAAP. The following information is necessary to reconcile the Italian consolidated annual report for 2006 to generally accepted accounting principles in the United States (U.S. GAAP).

Summary of significant differences between IFRS and U.S. GAAP
Eni’s Financial Statements at December 31, 2006 have been prepared in accordance with International Financial Reporting Standards (IFRS)10 adopted by the European Commission, which differ in certain aspects from U.S. GAAP. A description of the significant differences and their effects on net profit and shareholders’ equity is set forth in the following notes.

A) CONSOLIDATION POLICY
Eni’s consolidation policy is described under "Principles of consolidation" of the Notes to the Consolidated Financial Statements. In particular, under IFRS, the consolidated financial statements include also companies in which Eni holds less than 50% of the voting rights, but over which it exercises control in shareholders’ meetings.
Under U.S. GAAP, investments of less than 50% are accounted for by applying the equity method. Under U.S. GAAP, Saipem SpA and its subsidiaries are excluded from consolidation and are accounted for under the equity method. Under IFRS, Eni exercises control of Saipem SpA also without holding the majority of voting rights (43.54%) exercisable in shareholders' meetings. During 2006 Saipem Projects SpA (100% Saipem SpA) acquired from Eni SpA 100% of Snamprogetti SpA that, as a result, has been excluded from consolidation; for U.S. GAAP purposes the gain on this sale was recognized in the profit and loss account.

B) EXPLORATION & PRODUCTION ACTIVITIES

Exploration
Consistent with IFRS, the international specific criteria have been applied for hydrocarbons exploration and production activities. In particular, exploration costs, including successful exploratory wells, are recorded as intangible assets and are amortized in full in the period incurred (i.e., expensed as incurred for financial reporting purposes). Costs for the acquisition of exploration permits and for the extension of existing permits, are capitalized and amortized over the expected period of benefit.
Under U.S. GAAP, costs relating to exploratory wells are initially capitalized as "incomplete wells and other" until it is determined if commercial quantities of reserves have been discovered ("successful efforts method"). After completion of drilling and evaluation of the well, the capitalized costs are either charged to expense or reclassified as part of Eni’s proved mineral interests. Costs of exploratory wells that have found commercially producible quantities of reserves that cannot be classified as proved remain capitalized after the completion of drilling if: (i) such wells have found a sufficient quantity of reserves to justify completion as a producing wells; (ii) the enterprise is making sufficient progress assessing the reserves and the economic and operating viability of the project. If either condition is not met or if an enterprise obtains information that raises substantial doubt about the economic or operational viability of the project, the exploratory well is assumed to be impaired, and its costs, net of any salvage value, are charged to expense. Capitalized well costs related to proved properties are amortized over proved developed reserves on the basis of units of production. Other exploration costs, including geological and geophysical surveys, are expensed when incurred.

Development
Development costs are those costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering and storing oil and gas. Costs to operate and maintain wells and field equipment are expensed as incurred.
Under IFRS, costs of unsuccessful development wells are expensed immediately as loss on disposal. Costs of successful development wells are capitalized and amortized using the unit-of-production method.
Under U.S. GAAP, costs of productive wells and development dry holes, both tangible and intangible, are capitalized and amortized using the unit-of-production method.

C) VALUATION OF ASSETS AND SUBSEQUENT REVALUATION
Both IFRS and U.S. GAAP require that recoverability of carrying value of tangible and intangible assets with a definite useful life is checked using similar criteria, with the exception of the following aspects.
Under IFRS, in order to determine whether an impairment exists, the book value of an asset is compared with its recoverable amount which is represented by the greater of fair value, net of disposal costs and value in use which is calculated by

(10) |  | There are no relevant differences between the accounting principles approved by the European Commission and the ones issued by IASB.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

discounting estimated cash flows arising from the use of the asset and its sale at the end of its useful life. Impairment losses of assets different from goodwill are reversed when the situation giving rise to an impairment ceases to exist.
Under U.S. GAAP, the recoverability of the value of an asset used in the production process is first checked by comparing the carrying amount with the sum of undiscounted cash flows expected from use of the asset and its disposal at the end of its useful life. Only if the result of this first check is negative does the entity write the asset down using discounted future cash flows. Under U.S. GAAP reversals of impairment losses are not permitted.

D) DEFERRED TAX ASSETS AND LIABILITIES
Under IFRS, taxes payable relating to certain potential distributions from shareholders’ equity or upon liquidation of a company are accrued only to the extent such distributions are planned.
Under U.S. GAAP, deferred tax liabilities are recognized regardless of expected distribution of dividends or the disposal of investments. However, U.S. GAAP does not require the accrual of deferred taxes when the investment is a foreign subsidiary and there is sufficient evidence that profits will remain permanently invested in the entity.
The adjustment included in Note 37 - Reconciliation of net profit and shareholders’ equity determined under IFRS to U.S. GAAP, concerns the recognition of deferred taxes on shareholders’ equity regardless of its expected distribution and it is measured taking into account the exception provided for foreign subsidiaries. This adjustment includes also deferred tax assets and liabilities on other adjustments to U.S. GAAP.

E) INTANGIBLE ASSETS
Under U.S. GAAP, intangible assets include the recording, separately from goodwill, of assets acquired in or following business combinations arising from legal or contractual rights regardless of their ability to be transferred and of other assets owned by the entity that can be transferred individually or together with other assets and liabilities. If such intangible assets have definite lives they are amortized by the straight line method over their useful lives.
IFRS are consistent with U.S. GAAP. However, considering that in the first application of IFRS, Eni has decided not to restate business combinations, the value of the intangible assets described is recorded in the item "Goodwill".
Both under U.S. GAAP and IFRS, goodwill and intangible assets with an indefinite useful life are not amortized; these assets are subject to a yearly evaluation in order to define the relevant impairment if needed. Such accounting principles have been adopted starting from January 1, 2002 for U.S. GAAP and January 1, 2004 for IFRS. The adjustments for the reconciliation of shareholders' equity included in Note 37 - Reconciliation of net profit and shareholders’ equity determined under IFRS to U.S. GAAP, concern the reversal of the amortization of goodwill for the years 2002 and 2003.

F) INVENTORIES
Under U.S. GAAP, crude oil, petroleum products and natural gas inventories are calculated using the LIFO method.
Under IFRS the LIFO method is not permitted.

G) PROVISIONS FOR EMPLOYEE BENEFITS
Both under U.S. GAAP and IFRS liabilities related to defined benefit plans and long-term employee benefits are determined by adopting actuarial assumptions. The application of the corridor approach is allowed. Under the corridor approach the actuarial gains and losses of defined benefit plans, deriving from a change in the actuarial assumptions used or from a change in the conditions of the plan, are charged to the profit and loss account, proportionally through the residual average working life of the employees participating to the plan, in the limits of the share of the discounted profit/loss not charged beforehand, that exceeds the greater of 10% of liabilities and 10% of the fair value of the plan assets.
Under IFRS, following the application of the corridor approach, the liability for employee benefits is recognised in the caption "Provisions for employee benefits" and excludes actuarial incomes and losses not charged to the profit and loss account. Plan assets are measured on the basis of their expected return.
Under U.S. GAAP plan assets are measured on the basis of their effective return. The actuarial liability recognized in the balance sheet includes the total amount of incomes and losses deriving from changes in actuarial assumptions; changes of liabilities relating to actuarial incomes and losses not accounted in the profit and loss account are recognized, net of the related deferred tax effect with a corresponding entry to the item of the shareholders’ equity "Other comprehensive income".11 In the following periods, the actuarial incomes and losses "suspended" in other comprehensive income are recognised in the profit and loss account according to the corridor method.

(11) |  | The difference between IFRS and U.S. GAAP takes into consideration the adoption of SFAS 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (SFAS 158); the effects of the adoption of SFAS 158 are described in the paragraph “Changes in accounting principles”.

Concentrations and certain significant estimates
The following information is presented according to Statement of Position 94-6 "Disclosures of Certain Significant Risks and Uncertainties".
NATURE OF OPERATIONS
Eni is an integrated energy company operating in the oil and gas, electricity generation, petrochemicals and oilfield services and engineering industries.
EXPLORATION & PRODUCTION: through its Exploration & Production Division and subsidiaries, Eni engages in hydrocarbon exploration and production in Italy, North Africa (Algeria, Egypt, Libya and Tunisia), West Africa (Angola, Congo and Nigeria), the North Sea (Norway and the United Kingdom), Latin America (Venezuela), the former Soviet Union countries (mainly Kazakhstan), the United States (Gulf of Mexico and Alaska) and Asia (mainly Saudi Arabia, China, India, Indonesia, Iran and Pakistan). In 2005 approximately 68% of oil production sold was supplied to Eni’s Refining & Marketing segment and approximately 40% of natural gas production sold was supplied to Eni’s Gas & Power segment.
Eni owns a storage system, made up by eight depleted fields, which is used for the modulation of supply in accordance with seasonal swings in demand (natural gas is stored in the summer and used in the winter), as strategic reserve to ensure supply and to support domestic production through mineral storage. Storage assets are owned by Stoccaggi Gas Italia (Eni 100%), a company constituted in accordance with Law Decree No. 164/2000 that introduced laws for the liberalization of the Italian natural gas market.

GAS & POWER: Econstituted by ni is engaged in the supply, transmission and sale of natural gas in Italy and outside Italy through its Gas & Power Division, which was the incorporation of Snam SpA into Eni SpA in 2002, and through certain subsidiaries. Approximately 92% of total purchases are purchased from foreign sources (primarily Algeria, Russia, The Netherlands and Norway) under long-term contracts, which contain take-or-pay provisions, and transported to Italy through a network of over 4,300 kilometers of international pipelines of which Eni owns the transmission rights. The remaining purchases in Italy are obtained principally from domestic gas produced by Eni’s Exploration & Production segment. Through an approximately 30,800-kilometer long network (corresponding approximately to 96% of the Italian domestic natural gas network), Eni supplies natural gas to residential and commercial users (civil market), industrial users and the power generation segment. Snam Rete Gas (Eni 53.39%), that was constituted in accordance with Law Decree No. 164/2000, owns the pipelines network used by Eni. Snam Rete Gas, a company listed on the Italian Stock Exchange, engages in natural gas transportation activities also for other operators of the segment. Following the merging of Italgas Più, Eni supplies natural gas directly to approximately five million customers in the residential and commercial segment. Through Italgas (Eni 100%), Eni is engaged in domestic distribution of natural gas in Italy through an approximately 48,000-kilometer long network.
Eni is engaged in distribution and sale of natural gas to residential and commercial customers outside Italy, in Argentina through Distribuidora de Gas Cuyana, in Hungary through Tigáz and in Slovenia through Adriaplin.
Legislative Decree No.164/2000 introduced laws for the liberalization of the Italian natural gas market with great impact on Eni’s activities, as the company is present in all the phases of the natural gas chain. The most important aspects of the decree are the following:
- total free market after 2003;

216

##### Contents

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

- until December 31, 2010 the imposition of thresholds to operators in relation to a percentage share of domestic consumption set as follows: (i) 75%, by January 1, 2002, for imported or domestically produced natural gas volumes introduced in the domestic transmission network in order to sell it. This percentage decreases by two percentage points per year until it reaches 61% in 2009; (ii) 50% from January 1, 2003 for sales to final customers. These ceilings are calculated net of own consumption and, in case of sales, also net of losses. In 2006 Eni’s presence in the Italian natural gas market was in accordance with the above limitations;
- tariffs for transport infrastructure, storage, use of LNG terminals and distribution networks are set by the Authority for Electricity and Gas;
- third parties are allowed to access natural gas infrastructure according to set conditions.
Eni through EniPower SpA (Eni 100%) and subsidiaries is engaged in managing Eni’s electricity business at the power plants located in the Ferrera Erbognone, Ravenna, Livorno, Taranto, Mantova, Brindisi and Ferrara industrial sites with installed capacity of 4.5 gigawatts and a production sold of 24.82 terawatthours. The demand for gas and fuel oils of EniPower’s stations is met by Eni supplies.

REFINING & MARKETING: Eni, through its Refining & Marketing Division, which was constituted by the incorporation of AgipPetroli SpA in Eni SpA in 2002 and certain subsidiaries, engages in petroleum refining and marketing activities primarily in Italy and Europe. Eni is the largest refiner of petroleum products in Italy in terms of overall refining capacity. Approximately 56% of crude oil sold is purchased from Eni’s Exploration & Production segment, the rest is purchased from producing countries pursuant to purchase contracts (28%) and in spot markets (16%). Approximately 58% of the purchased crude oil is refined. 35.9% of oil refined derives from the production of Eni’s Exploration & Production segment.

PETROCHEMICALS: through Polimeri Europa SpA and subsidiaries (Eni 100%), Eni engages in manufacturing of olefins, aromatics, intermediate products, styrene and elastomers. Eni’s petrochemicals production is concentrated in Italy, the other operations being primarily in Western Europe. Approximately 23% of the oil-based feedstock requirements used by petrochemical plants are supplied by Eni’s Refining & Marketing segment.
ENGINEERING & CONSTRUCTION: through Saipem SpA (Eni 43%), a company listed on the ItalianStock Exchange, and its subsidiaries, Eni is engaged in construction and drilling services to customers in the oil and gas industries and is a provider of engineering and project management services to customers in the oil and gas and petrochemical industries. At December 31, 2006, 20% of the order backlog related to orders from Eni Group companies.

Accounting for suspended well costs
Effective January 1, 2005 Eni adopted Position FAS 19-1 (FSP 19-1), "Accounting for Suspended Well Costs". FSP 19-1 amended Statement of Financial Accounting Standards No. 19 (FAS 19) "Financial Accounting and Reporting by Oil and Gas Producing Companies". Following adoption of FSP 19-1, Eni temporarily capitalized exploratory drilling costs pending determination of whether the well has found proved reserves if both of the following conditions are met: (a) the well has found a sufficient quantity of reserves to justify, if appropriate, its completion as a producing well; and (b) the enterprise is making sufficient progress assessing the reserves and the economic and operating viability of the project. If either condition is not met or if an enterprise obtains information that raises substantial doubt about the economic or operational viability of the project, the exploratory well would be assumed to be impaired, and its costs, net of any salvage value, would be charged to expense. FSP 19-1 provided a number of indicators needing to be present to demonstrate sufficient progress was being made in assessing the reserves and economic viability of the project. Among these indicators are: (i) costs are being incurred to assess the reserves and their potential development; (ii) existence (or active negotiations) of sales contracts with customers for oil and natural gas; and (iii) existence of firm plans, established timetables or contractual commitments, which may include seismic testing and drilling of additional exploratory wells. The disclosures and discussion below address those suggested in FSP 19-1.

Changes in accounting principles

On September 2005, the Emerging Issues Task Force ("EITF") issued Issue No. 04-13 ("EITF 04-13"), "Accounting for Purchases and Sales of Inventory with the Same Counterparty." The EITF concluded that inventory purchases and sales transactions with the same counterparty should be combined for accounting purposes if they were entered into in contemplation of each other. The EITF provided indicators to be considered for purposes of determining whether such transactions are entered into in contemplation of each other. Guidance was also provided on the circumstances under which non-monetary exchanges of inventory within the same line of business should be recognized at fair value. EITF 04-13 became effective in reporting periods beginning after March 15, 2006. Eni adopted EITF 04-13 starting from April 1, 2006. The adoption of EITF 04-13 did not have material effect on Eni’s Consolidated Financial Statements according to U.S. GAAP.
Effective January 1, 2006, the Company adopted SFAS No. 123-R, "Share-Based Payment" ("SFAS 123R"), using the modified prospective method. SFAS 123R establishes the accounting for equity instruments exchanged for employee services. Under SFAS 123R, share-based compensation cost is measured at the grant date based on the calculated fair value of the award. The expense is recognized over the employees’ requisite service period, generally the vesting period of the award. SFAS 123R also requires the related excess tax benefit received upon exercise of stock options or vesting of restricted stock, if any, to be reflected in the statement of cash flows as a financing activity rather than an operating activity. The adoption of this standard did not have material effect on Eni’s Consolidated Financial Statements according to U.S. GAAP.
As of December 31, 2006, Eni applies SFAS 158 which requires that the provision for employees benefits equals the total actuarial liability and therefore includes the total amount of incomes and losses resulting from changes in actuarial assumptions. Actuarial incomes and losses not accounted in the profit and loss account are recognized, net of the related fiscal effect, with a corresponding entry to the item of the shareholders’ equity "Other comprehensive income". In the following periods, the actuarial profits and losses "suspended" in other comprehensive income are recognized in the profits and loss account according to the corridor method.
The effect of the adoption of SFAS 158 consist in the following:

(million euro) |  |  |
Net actuarial losses at December 31, 2005 |  | 128 |
Net actuarial losses recognized in 2006 profit and loss account |  | (28 | )
Change in net actuarial losses |  | (65 | )
Change in consolidation |  | (3 | )
Net actuarial losses at December 31, 2006 |  | 32 |

Actuarial losses expected to be recognized in profit and loss account during 2007 amount to euro 3 million.

Recent accounting principles
On June 2006, FASB issued Interpretation No. 48 "Accounting for uncertainty in income taxes" (FIN 48) that prescribes criteria for recognition and measurement of entity’s tax benefits ("tax positions") which present uncertainty regards of being realized. The requirements of FIN 48 prescribes that an entity shall recognize in financial statements defined tax positions only when it is considered "more likely than not" that their positive effects will be realized. The value of the tax position that shall be recognized in financial statements is measured at the largest amount of benefit that is greater than 50% likely of being realized.
Any differences between tax positions taken in a tax return and amounts recognized in the financial statements represent liabilities to be recognized in the balance sheet. FIN 48 is effective starting from January 1, 2007.
On September 2006, FASB issued Statement of Financial Accounting Standard n. 157 "Fair value measurement" (SFAS 157). SFAS 157 establishes a framework that applies when U.S. GAAP require fair value measurements of asset and liabilities. According to SFAS 157, fair value is measured mainly on the assumptions used by market participants rather than entity internal assumptions. The use of entity internal assumptions is allowed only for situations in which there are no information readily available on the market; therefore, in this circumstance, the entity adapts its internal assumptions to those used by market participants. SFAS 157 establishes a fair value "hierarchy" articulated on three levels according to the different quality of input used in the measurement. SFAS 157 is effective starting from 2008.
On February 2007, FASB issued Statement of Financial Accounting Standard No. 159 "The Fair Value option for Financial Assets and Financial Liabilities - Including an Amendment of FASB Statement No. 115" (SFAS 159). SFAS 159, in order to permit consistent measurement of assets and liabilities connected, reducing volatility of financial results, provides the option to evaluate certain financial and non financial asset and liabilities at fair value (fair value option). The decision of apply fair value option is irrevocable. SFAS 159 is effective starting from 2008.
Eni presently is analyzing the new accounting principles and, at the moment, cannot determine if their adoption will have a significant effect on Eni’s Consolidated Financial Statements according to U.S. GAAP.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

RESULTS OF OPERATIONS FROM OIL AND GAS PRODUCING ACTIVITIES
Results of operations from oil and gas producing activities, including gas storage services used to modulate the seasonal variation of demand, represent only those revenues and expenses directly associated to such activities including operating overheads. These amounts do not include any allocation of interest expense or general corporate overhead and, therefore, are not necessarily indicative of the contributions to consolidated net earnings of Eni. Related income taxes are computed by applying the local income tax rates to the pre-tax income from producing activities. Eni is a party to certain Production Sharing Agreements (PSAs) whereby a portion of Eni’s share of oil and gas production is withheld and sold by its joint venture partners which are state-owned entities, with proceeds being remitted to the state in satisfaction of Eni’s PSA-related tax liabilities. Revenue and income taxes include such taxes owed by Eni but paid by state-owned entities out of Eni’s share of oil and gas production. Results of operations from oil and gas producing activities by geographical area consist af the following:

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

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.
Net proved reserves exclude royalties and interests owned by others.
Proved developed oil and gas 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.
Eni’s proved reserves have been estimated on the basis of the applicable U.S. Securities & Exchange Commission regulation, Rule 4-10 of Regulation S-X and its interpretations and have been disclosed in accordance with Statement of Financial Accounting Standard No. 69. The estimates of proved reserves, developed and undeveloped for years ended December 31, 2003, 2004, 2005 and 2006 are based on data prepared by Eni. Since 1991, Eni has requested qualified independent oil engineering companies carry out an independent evaluation12 of its proved reserves on a rotational basis. In particular a total of 1.4 billion boe of proved reserves, or about 21% of Eni’s total proved reserves at December 31, 2006, have been evaluated. The results of this independent evaluation confirmed Eni’s evaluations, as in previous years. In the 2004-2006 three-year period, 76% of Eni’s total proved reserves were subject to independent evaluations.
Eni operates under Production Sharing Agreements, (PSAs), in several of the foreign jurisdictions where it has oil and gas exploration and production activities. Reserves of oil and natural gas to which Eni is entitled under PSA arrangements are shown in accordance with Eni’s economic interest in the volumes of oil and natural gas 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 represented 51%, 48% and 53% of total proved reserves as of year-end 2004, 2005 and 2006, respectively, on an oil-equivalent basis.
A similar scheme to PSAs applies to Service and "Buy-Back" contracts; proved reserves associated with such contracts represented 3%, 2% and 2% of total proved reserves on an oil-equivalent basis as of year-end 2004, 2005 and 2006, respectively.
Oil and gas reserve quantities include: (i) oil and natural gas quantities in excess to cost recovery which the company has an obligation to purchase under certain PSAs with governments or authorities whereby the company serves as producer of reserves. In accordance with SFAS No. 69, paragraph 13, reserve volumes associated with such oil and gas quantities represented 1.4%, 1.7% and 1.1% of total proved reserves as of year-end 2004, 2005 and 2006 respectively, on an oil-equivalent basis; (ii) volumes of natural gas used for own consumption and (iii) volumes of natural gas held in certain Eni storage fields in Italy. Proved reserves attributable to these fields include: (a) the residual natural gas volumes of the reservoirs and (b) 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 sold.
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 judgment. Results of drilling, testing and production after the date of the estimate may require substantial upward or downward revision. In addition, changes in oil and natural gas prices have an effect on the quantities of Eni’s proved reserves since estimates of reserves are based on prices and costs relative to the date when such estimates are made. Reserve estimates are also subject to revision as prices fluctuate due to the cost recovery feature under certain PSAs.
The following table presents yearly changes by geographical area in estimated proved reserves, developed and undeveloped, of crude oil (including condensate and natural gas liquids) and natural gas for the years 2004, 2005 and 2006.

ENI ANNUAL REPORT 2006 / NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

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 as of December 31, 2004, 2005 and 2006 include amounts that Eni’s Gas & Power segment and other gas companies correspond for storages services, required to support market demand flexibility needs.
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.
