GLOSSARY

A 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 |  |
Leverage |  | A non-GAAP measure of the Company’s financial condition, calculated as the ratio between net borrowings and shareholders’ equity, including non-controlling interest. For a discussion of management’s view of the usefulness of this measure and its reconciliation with the most directly comparable GAAP measure which in the case of the Company refers to IFRS, see "Item 5 – Financial Condition".
Net borrowings |  | Eni evaluates its financial condition by reference to "net borrowings", which is a non-GAAP measure. Eni calculates net borrowings as total finance debt less: cash, cash equivalents and certain very liquid investments not related to operations, including among others non-operating financing receivables and securities not related to operations. Non-operating financing receivables consist of amounts due to Eni’s financing subsidiaries from banks and other financing institutions and amounts due to other subsidiaries from banks for investing purposes and deposits in escrow. Securities not related to operations consist primarily of government and corporate securities. For a discussion of management’s view of the usefulness of this measure and its reconciliation with the most directly comparable GAAP measure which in the case of the Company refers to IFRS, see "Item 5 – Financial Condition".
Business terms |  |
AEEG (Authority for Electricity and Gas) |  | The Regulatory Authority for Electricity and Gas is the Italian independent body which regulates, controls and monitors the electricity and gas sectors and markets in Italy. The Authority’s role and purpose is to protect the interests of users and consumers, promote competition and ensure efficient, cost-effective and profitable nationwide services with satisfactory quality levels.
Associated gas |  | Associated gas is a natural gas found in contact with or dissolved in crude oil in the reservoir. It can be further categorized as Gas-Cap Gas or Solution Gas.
Average reserve life index |  | Ratio between the amount of reserves at the end of the year and total production for the year.
Barrel/BBL |  | Volume unit corresponding to 159 liters. A barrel of oil corresponds to about 0.137 metric tons.
BOE |  | Barrel of Oil Equivalent. It is used as a standard unit measure for oil and natural gas. The latter is converted from standard cubic meters into barrels of oil equivalent using a certain coefficient (see "Conversion Table").
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 exploration, development and production activities and for this reason it acquires a right to hydrocarbons extracted against the payment of royalties on production and taxes on oil revenues to the state.
Condensates |  | Condensates is a mixture of hydrocarbons that exists in the gaseous phase at original reservoir temperature and pressure, but that, when produced, is in the liquid phase at surface pressure and temperature.
Contingent resources |  | Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations, but the applied project(s) are not yet considered mature enough for commercial development due to one or more contingencies.
Conversion capacity |  | Maximum amount of feedstock that can be processed in certain dedicated facilities of a refinery to obtain finished products. Conversion facilities include catalytic crackers, hydrocrackers, visbreaking units, and coking units.
Conversion index |  | Ratio of capacity of conversion facilities to primary distillation capacity. The higher the ratio, the higher is the capacity of a refinery to obtain high value products from the heavy residue of primary distillation.
Deep waters |  | Waters deeper than 200 meters.
Development |  | Drilling and other post-exploration activities aimed at the production of oil and gas.

##### Table of Contents

Enhanced recovery |  | Techniques used to increase or stretch over time the production of wells.
EPC |  | Engineering, Procurement and Construction.
EPIC |  | Engineering, Procurement, Installation and Construction.
Exploration |  | Oil and natural gas exploration that includes land surveys, geological and geophysical studies, seismic data gathering and analysis and well drilling.
FPSO |  | Floating Production Storage and Offloading System.
FSO |  | Floating Storage and Offloading System.
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 back into its natural gaseous state and consumed. One tonne 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.
Margin |  | The difference between the average selling price and direct acquisition cost of a finished product or raw material excluding other production costs (e.g. refining margin, margin on distribution of natural gas and petroleum products or margin of petrochemical products). Margin trends reflect the trading environment and are, to a certain extent, a gauge of industry profitability.
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 |  | According to Legislative Decree No. 164/2000, these are volumes required for allowing optimal operation of natural gas fields in Italy for technical and economic reasons. The purpose is to ensure production flexibility as required by long-term purchase contracts as well as to cover technical risks associated with production.
Modulation Storage |  | According to Legislative Decree No. 164/2000, these are volumes required for meeting hourly, daily and seasonal swings in demand.
Natural gas liquids (NGL) |  | 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 were previously defined as natural gasoline, are natural gas liquids.
Network Code |  | A code containing norms and regulations for access to, management and operation of natural gas pipelines.
Over/Under lifting |  | Agreements stipulated between partners which regulate the right of each to its share in the production for a set period of time. Amounts lifted by a partner different from the agreed amounts determine temporary Over/Under lifting situations.
Possible reserves |  | Possible reserves are those additional reserves that are less certain to be recovered than probable reserves.
Probable reserves |  | Probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered.
Primary balanced refining capacity |  | Maximum amount of feedstock that can be processed in a refinery to obtain finished products measured in BBL/d.
Production Sharing Agreement ("PSA") |  | Contract in use in African, Middle Eastern, Far Eastern and Latin American countries, among others, regulating relationships between states and oil companies with regard to the exploration and production of hydrocarbons. The mineral right is awarded to the national oil company jointly with the foreign oil company that has an exclusive right to perform exploration, development and production activities and can enter into 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 and "profit oil" is

##### Table of Contents

|  | divided between the contractor and the national company according to variable schemes and represents the profit deriving from exploration and production. Further terms and conditions of these contracts may vary from country to country.
Proved reserves |  | Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible, from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. Reserves are classified as either developed and undeveloped. Proved developed oil and gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well, and through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well. Proved undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.
Reserves |  | Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project.
Reserve life index |  | Ratio between the amount of proved reserves at the end of the year and total production for the year.
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 amount of reserves – in PSAs – due to changes in international oil prices.
Ship-or-pay |  | Clause included in natural gas transportation contracts according to which the customer is requested to pay for the transportation of gas whether or not the gas is actually transported.
Strategic Storage |  | According to current Italian regulation, these are volumes required for covering lack or reduction of supplies from extra-European sources or crises in the natural gas system.
Take-or-pay |  | Clause included in natural gas supply contracts according to which the purchaser is bound to pay the contractual price or a fraction of such price for a minimum quantity of gas set in the contract whether or not the gas is collected by the purchaser. The purchaser has the option of collecting the gas paid for 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 and gas sector that are downstream of exploration and production activities.

(*) |  | In this Annual Report on Form 20-F, the Company presents oil and gas production volumes and reserves expressed in barrels of oil-equivalent whereby natural gas volumes are converted on the base of an equivalency. In 2010, Eni updated the natural gas conversion factor from 5,742 to 5,550 standard cubic feet of gas per barrel of oil equivalent. This update reflected changes in Eni’s gas properties that took place in recent years and was assessed by collecting data on the heating power of gas in all Eni’s 230 gas fields on stream at the end of 2009. The effect of this update on production expressed in BOE was 26 KBOE/d for the full year 2010 and on the initial reserves balances as of January 1, 2010 amounted to 106 mmBOE. Other per-BOE indicators were only marginally affected by the update (e.g. realization prices, costs per BOE) and also negligible was the impact on depletion charges. Other oil companies may use different conversion rates.

(1) | i | From 2009, gains and losses on non-hedging commodity derivative instruments, including both fair value re-measurement and gains and losses on settled transactions are reported as items of operating profit. Also results of the gas storage business are reported within the Gas & Power segment reporting unit, as part of the regulated businesses results, following the restructuring of Eni’s regulated gas businesses in Italy. In past years, results of the gas storage business were reported within the Exploration & Production segment. Data for the years ended December 31, 2008 and 2007 have been restated. Prior year data have not been restated.
(2) | i | From 2010 certain environmental provisions incurred by the Parent Company Eni SpA due to inter-company guarantees on behalf of Syndial have been reported within the segment reporting unit "Other activities". Data for the years 2008 and 2009 have been restated by increasing the operating loss of the "Other activities" segment by euro 120 million and euro 54 million, respectively. Prior-year data have not been restated.
(3) | i | This item mainly pertained to intra-group sales of commodities, services and capital goods recorded in the assets of the purchasing business segment as of the end of the period.
(4) | i | Euro per share or U.S. dollars per American Depositary Receipt (ADR), as the case may be. One ADR represents two Eni shares. The dividend amount for 2010 is based on the proposal of Eni’s management which is submitted to approval of the Annual General Shareholders’ Meeting scheduled on April 29 and May 5, 2011 on first and second calls, respectively.
(5) | i | Eni’s financial statements are stated in euro. The translations of certain euro amounts into U.S. dollars are included solely for the convenience of the reader. The convenient translations should not be construed as representations that the amounts in euro have been, could have been, or could in the future be, converted into U.S. dollars at this or any other rate of exchange. Data per ADR, with the exception of dividends, were translated at the EUR/U.S. $ average exchange rate as recorded by in the Federal Reserve Board official statistics for each year presented (see the table on page 5). Dividends per ADR for the years 2006 through 2009 were translated into U.S. dollars for each year presented using the Noon Buying Rate on payment dates, as recorded on the payment date of the interim dividend and of the balance to the full-year dividend, respectively. The dividend for 2010 based on the management’s proposal to the General Shareholders’ Meeting and subject to approval was translated as per the portion related to the interim dividend (euro 1 per ADR) at the Noon Buying Rate recorded on the payment date on September 30, 2010, while the balance of euro 1 per ADR was translated at the Noon Buying Rate as recorded on December 31, 2010. The balance dividend for 2010 once the full-year dividend is approved by the Annual General Shareholders’ Meeting is payable on May 26, 2011 to holders of Eni shares, being the ex-dividend date May 23, while ADRs holders will be paid late in May 2011.

Selected Operating Information

The tables below set forth selected operating information with respect to Eni’s proved reserves, developed and undeveloped, of crude oil (including condensates and natural gas liquids) and natural gas, as well as other data as of and for the years ended December 31, 2006, 2007, 2008, 2009 and 2010. Data on production of oil and natural gas and hydrocarbon production sold includes Eni’s share of production of affiliates and joint ventures accounted for under the equity or cost method of accounting. In presenting data on production volumes and reserves for total hydrocarbons, natural gas volumes have been converted to oil-equivalent barrels on the basis of a certain equivalency. In 2010, Eni updated the natural gas conversion factor from 5,742 to 5,550 standard cubic feet of gas per barrel of oil equivalent. This update reflected changes in Eni’s gas properties that took place in recent years and was assessed by collecting data on the heating power of gas in all Eni’s 230 gas fields on stream at the end of 2009. The effect of this update on production expressed in boe was 26 KBOE/d for the full year 2010 and on the initial reserves balances as of January 1, 2010 amounted to 106 mmBOE. Prior-year converted amounts were not restated. Other per-boe indicators were only marginally affected by the update (e.g. realization prices, costs per boe) and also negligible was the impact on depletion charges. Other oil companies may use different conversion rates.

Risk Factors

> Competition

> There is strong competition worldwide, both within the oil industry and with other industries, to supply energy to the industrial, commercial and residential energy markets

Eni faces strong competition in each of its business segments.

• |  | In the Exploration & Production business, Eni faces competition from both international oil companies and state-owned oil companies for obtaining exploration and development rights, and developing and applying new technologies to maximize hydrocarbon recovery. Furthermore, Eni may face a competitive disadvantage in many of these markets because of its relatively smaller size compared to other international oil companies, particularly when bidding for large scale or capital intensive projects, and may be exposed to industry-wide cost increases to a greater extent compared to its larger competitors given its potentially smaller market power with respect to suppliers. If, as a result of those competitive pressures, Eni fails to obtain new exploration and development acreage, to apply and develop new technologies, and to control cost increases, its growth prospects and future results of operations and cash flows may be adversely affected.
• |  | In its natural gas business, Eni faces increasingly strong competition on both the Italian market and the European market driven by moderate growth prospects for demand over the short and medium-term, in the face of large gas availability on the marketplace. The latter was driven by material investments to expand

##### Table of Contents

|  | import capacity to Europe via pipeline which have been made by a number of operators, including Eni, in recent years. Also large availability of LNG on a worldwide scale has found an outlet at the European continental hubs driving the development of highly liquid spot gas markets. LNG availability was fuelled by the ramp-up of important upstream projects worldwide (new treatment trains in Qatar, Yemen and Russia) and commercial development of non-conventional gas resources in the USA which have reduced dependence on LNG imports. As natural gas is a commodity, gas oversupplies have caused suppliers to compete more aggressively on pricing thus pressuring gas margins in the whole sector. Management believes that a better balance between demand and supply on the European market will not be achieved until 2014 at the earliest. The described trends may negatively affect the Company’s future results of operations and cash flow in its natural gas business, also taking into account the Company’s contractual obligations to off-take minimum annual volumes of natural gas in accordance to its long-term gas supply contracts that include take-or-pay clauses. See the sector-specific risk section below.
• |  | Eni also faces competition from large, well-established European utilities and other international oil and gas companies in growing its market share and acquiring or retaining clients. A number of large clients, particularly electricity producers, in both the domestic market and other European markets have entered the wholesale market of natural gas by directly purchasing gas from producers and reselling it to wholesale or retail markets. At the same time, a number of national gas producers from countries with large gas reserves are planning to sell natural gas directly to final clients, which would threaten the market position of companies like Eni which resell gas purchased from producing countries to final customers. These developments may increase the level of competition in both the Italian and other European markets for natural gas and reduce Eni’s operating profit and cash flows.
• |  | In its domestic electricity business, Eni competes with other producers and traders from Italy or outside of Italy who sell electricity on the Italian market. The Company expects in the near future that increasing competition due to the weak GDP growth expected in Italy and Europe over the next one to two years will cause outside players to place excess production on the Italian market.
• |  | In retail marketing of refined products both in and outside Italy, Eni competes with third parties (including international oil companies and local operators such as supermarket chains) to obtain concessions to establish and operate service stations. Once established, Eni’s service stations compete primarily on the basis of pricing, services and availability of non-petroleum products. In Italy, there is pressure from political and administrative entities, including the Italian Antitrust Authority, to increase levels of competition in the retail marketing of fuels. Eni expects developments on this issue to further increase pressure on selling margins in the retail marketing of fuels.
• |  | In the Petrochemical segment, we face intense competition from well-established international players and state-owned petrochemical companies, particularly in the most commoditized market segments. Many of those competitors may benefit from cost advantages due to larger scale, looser environmental regulations, availability of oil-based feedstock, and more favorable location and proximity to end-markets. Excess capacity and sluggish economic growth may exacerbate competitive pressures. The Company expects continuing margin pressures in the foreseeable future as a result of those trends.
• |  | Competition in the oil field services, construction and engineering industries is primarily based on technical expertise, quality and number of services and availability of technologically advanced facilities (for example, vessels for offshore construction). Lower oil prices could result in lower margins and lower demand for oil services.

The Company’s failure or inability to respond effectively to competition could adversely impact the Company’s growth prospects, future results of operations and cash flows.

> Risks associated with the exploration and production of oil and natural gas

The exploration and production of oil and natural gas requires high levels of capital expenditures and entails particular economic risks. It is subject to natural hazards and other uncertainties including those relating to the physical characteristics of oil and natural gas fields.

Eni’s results depend on its ability to identify and mitigate the risks and hazards inherent to operating in the crude oil and natural gas industry. The Company seeks to minimize these operational risks by carefully designing and building its facilities and conducting its operations in a safe and reliable manner. However, failure to manage these risks effectively could result in unexpected incidents, including releases, explosions or mechanical failures resulting in personal injury, loss of life, environmental damage, loss of revenues, legal liability and/or disruption to operations. As recent events in the Gulf of Mexico have shown, exploration and production carries certain inherent risks, especially deep water drilling. Accidents at a single well can lead to loss of life, environmental damage and consequently potential economic losses that could have a material and adverse effect on the business, results of operation and prospects of the Group. Eni has implemented and maintains a system of policies, procedures and compliance mechanisms to manage safety, health, environmental, reliability and efficiency risks; to verify compliance with applicable laws and policies; and to respond to and learn from unexpected incidents. Nonetheless,

##### Table of Contents

in certain situations where Eni is not the operator, the Company may have limited influence and control over third parties, which may limit its ability to manage and control such risks. Eni maintains insurance coverage that include coverage for physical damage to our assets, third party liability, workers’ compensation, pollution and other damage to the environment and other coverage. Our insurance is subject to caps, exclusion and limitation, and there is no assurance that such coverage will adequately protect us against liabilities from all potential consequences and damages. In light of the accident at the Macondo well in the Gulf of Mexico, we may not be able to secure similar coverage for the same costs. Future insurance coverage for our industry could increase in cost and may include higher retentions. Also, some forms of insurance may become unavailable in the future or unavailable on terms that we believe are economically acceptable.

The production of oil and natural gas is highly regulated and is subject to conditions imposed by governments throughout the world in matters such as the award of exploration and production interests, the imposition of specific drilling and other work obligations, income taxes and taxes on production, environmental protection measures, control over the development and abandonment of fields and installations, and restrictions on production.

> Exploratory drilling efforts may be unsuccessful

Drilling for oil and gas involves numerous risks including the risk of dry holes or failure to find commercial quantities of hydrocarbons. The costs of drilling, completing and operating wells are often uncertain, and drilling operations may be unsuccessful as a result of a variety of factors, including unexpected drilling conditions, pressure or irregularities in formations, equipment failures or fires, blow-outs and various forms of accidents, marine risks such as collisions and adverse weather conditions and shortages or delays in the delivery of equipment. Exploring or drilling in offshore areas, particularly in deep waters, is generally more complex and riskier than in onshore areas; the same is true for exploratory activity in remote areas or in challenging environmental conditions such as those we are experiencing in the Caspian region or Alaska. Failure to discover commercial quantities of oil and natural gas could have an adverse impact on Eni’s future growth prospects, results of operations and liquidity. Because Eni plans to invest significant capital expenditures in executing high risk exploration projects, it is likely that Eni will incur significant exploration and dry hole expenses in future years. Eni plans to explore for oil and gas offshore; a number of projects are planned in deep and ultra-deep waters or at deep drilling depths, where operations are more difficult and costly than in other areas. Deep water operations generally require a significant amount of time before commercial production of reserves can commence, increasing both the operational and financial risks associated with these activities. The Company plans to conduct risky exploration projects offshore the Gulf of Mexico, Egypt, Angola, Italy, Australia, Nigeria and Norway. In 2010, the Company invested approximately euro 1 billion in executing exploration projects and it plans to spend approximately euro 0.9 billion per annum on average over the next four years.

Furthermore, shortage of deep water rigs and failure to find additional commercial reserves could reduce future production of oil and natural gas which is highly dependent on the rate of success of exploratory activity.

> The oil and gas industry may face increased regulation both in the USA and elsewhere that could increase the cost of regulatory compliance and may require changes to our drilling operations and exploration and development plans and may lead to higher royalties and taxes

The recent incident at the BP-operated Macondo well in the Gulf of Mexico is likely to result in more stringent regulation of oil and gas activities in the U.S. and elsewhere, particularly relating to environmental and health and safety protection controls and oversight of drilling operations, as well as access to new drilling areas. The U.S. Government had imposed a six-month moratorium, which was suspended in October 2010, on certain offshore drilling activities. The moratorium forced Eni’s management to reschedule certain projects and caused delays in linking a few wells to production facilities, which had a negligible impact on the Company’s production for the year. In addition, the Group incurred operating costs related to inactivity or redeployment of certain drilling rigs which were booked before the moratorium. During the first months of 2011, Eni expects to resume the operations that had been previously authorized and then suspended following the moratorium. Planned activities for which authorizations have still to be granted may be rescheduled due to uncertainties in the timing of obtaining the necessary authorizations from the U.S. Authorities. Similar actions have been taken by governments elsewhere in the world. The European Parliament has increased regulations in the area of environmental protection in the field of hydrocarbon extraction and Italian Authorities have passed legislation that would introduce certain restrictions to activities for exploring and producing hydrocarbons. These new regulations and legislation, as well as evolving practices, could increase the cost of compliance and may require changes to our drilling operations and exploration and development plans and may lead to higher royalties and taxes.

> Development projects bear significant operational risks which may adversely affect actual returns on such projects

Eni is involved in a number of development projects for producing hydrocarbon reserves. Certain projects are planned to develop reserves in high risk areas, particularly offshore and in remote and hostile environments. Eni’s future results of operations and liquidity rely upon its ability to develop and operate major projects as planned. Key factors that may affect the economics of these projects include:

• |  | the outcome of negotiations with co-venturers, governments, suppliers, customers or others including, for example, Eni’s ability to negotiate favorable long-term contracts with customers; the development of reliable spot markets that may be necessary to support the development of particular production projects, or commercial arrangements for pipelines and related equipment to transport and market hydrocarbons. Furthermore, projects executed with partners and co-venturers reduce the ability of the Company to manage risks and costs, and Eni could have limited influence over and control of the operations, behaviors and performance of its partners;
• |  | timely issuance of permits and licenses by government agencies;
• |  | the Company’s relative size compared to its main competitors which may prevent it from affording opportunities to participate in large-scale projects or affect its ability to reap benefits associated with economies of scale, for example by obtaining more favorable contractual terms by suppliers of goods and services;
• |  | the ability to design development projects so as to prevent the occurrence of technical inconvenience;
• |  | delays in manufacturing and delivery of critical equipment, or shortages in the availability of such equipment, causing cost overruns and delays;
• |  | risks associated with the use of new technologies and the inability to develop advanced technologies to maximize the recoverability rate of hydrocarbons or gain access to previously inaccessible reservoirs;
• |  | changes in operating conditions and costs. The industry has been impacted for a few years to date by rising trends in the cost for certain critical productive factors including specialized labor, procurement costs and costs for leasing third party equipment or purchase services such as drilling rigs as a result of industry-wide cost inflation. The Company expects that costs in its upstream operations will continue to rise in the foreseeable future;
• |  | the actual performance of the reservoir and natural field decline; and
• |  | the ability and time necessary to build suitable transport infrastructures to export production to final markets.

Furthermore, deep waters and other hostile environments, where the majority of Eni’s planned and existing development projects are located, can exacerbate these problems. Delays and differences between scheduled and actual timing of critical events, as well as cost overruns may adversely affect actual returns of development projects. Finally, developing and marketing hydrocarbons reserves typically requires several years after a discovery is made. This is because a development project involves an array of complex and lengthy activities, including appraising a discovery in order to evaluate its commercial potential, sanctioning a development project and building and commissioning related facilities. As a consequence, rates of return for such long-lead-time projects are exposed to the volatility of oil and gas prices which may be substantially lower with respect to prices assumed when the investment decision was actually made, leading to lower rates of return. For example, we have experienced material cost overruns and a substantial delay in the scheduling of production start-up at the Kashagan field, where development is ongoing. Those negative trends were driven by a number of factors including depreciation of the U.S. dollar versus the euro and other currencies; cost escalation of goods and services required to execute the project; an original underestimation of the costs and complexity to operate in the North Caspian Sea due to lack of benchmarks; design changes to enhance the operability and safety standards of the offshore facilities. The partners of the venture are currently discussing an update of the expenditures and time schedule to complete the Phase 1 which were included in the development plan approved in 2008 by the relevant Kazakh Authorities. The Consortium continues to target the achievement of first commercial oil production by end of 2012. However, the timely delivery of Phase 1 depends on a number of factors which are presently under review.

See "Item 4 – Exploration & Production – Caspian Sea" for a full description of the material terms of the Kashagan project.

In the event the Company is unable to develop and operate major projects as planned, particularly if the Company fails to accomplish budgeted costs and time schedules, it could incur significant impairment charges associated with reduced future cash flows of those projects on capitalized costs.

> Inability to replace oil and natural gas reserves could adversely impact results of operations and financial condition

Eni’s results of operations and financial condition are substantially dependent on its ability to develop and sell oil and natural gas. Unless the Company is able to replace produced oil and natural gas, its reserves will decline.

##### Table of Contents

In addition to being a function of production, revisions and new discoveries, the Company’s reserve replacement is also affected by the entitlement mechanism in its Production Sharing Agreements ("PSAs") and similar contractual schemes. In accordance with such contracts, Eni is entitled to a portion of a field’s reserves, the sale of which is intended to cover expenditures incurred by the Company to develop and operate the field. The higher the reference prices for Brent crude oil used to estimate Eni’s proved reserves, the lower the number of barrels necessary to recover the same amount of expenditures. In 2010, the Company’s reserve replacement was negatively affected by lower entitlements in its PSAs for an estimated amount of 80 mmBOE, which however did not impair the Company’s ability to fully replace reserves produced in the year. Due to ongoing trends in crude oil prices, the Company expects a risk of lower production and reserve entitlement relating to its PSA contracts to occur in 2011. See "Item 4 – Business Overview – Exploration & Production" and "Item 5 – Management’s Expectations of Operations". Future oil and gas production is dependent on the Company’s ability to access new reserves through new discoveries, application of improved techniques, success in development activity, negotiation with countries and other owners of known reserves and acquisitions. An inability to replace reserves could adversely impact future production levels and growth prospects, thus negatively affecting Eni’s future results of operations and financial condition.

> Changes in crude oil and natural gas prices may adversely affect Eni’s results of operations

The exploration and production of oil and gas is a commodity business with a history of price volatility. The single largest variable that affects the Company’s results of operations and financial condition is crude oil prices. Lower crude oil prices have an adverse impact on Eni’s results of operations and cash flow. Eni generally does not hedge exposure to fluctuations in future cash flows due to crude oil price movements. As a consequence, Eni’s profitability depends heavily on crude oil and natural gas prices.

Crude oil and natural gas prices are subject to international supply and demand and other factors that are beyond Eni’s control, including among other things:

(i) |  | the control on production exerted by the Organization of the Petroleum Exporting Countries ("OPEC") member countries which control a significant portion of the world’s supply of oil and can exercise substantial influence on price levels;
(ii) |  | global geopolitical and economic developments, including sanctions imposed on certain oil-producing countries on the basis of resolutions of the United Nations or bilateral sanctions;
(iii) |  | global and regional dynamics of demand and supply of oil and gas; in the current economic downturn we have experienced a significant reduction in worldwide demand for crude oil and in the European gas demand which have negatively impacted crude oil and natural gas prices;
(iv) |  | prices and availability of alternative sources of energy;
(v) |  | governmental and intergovernmental regulations, including the implementation of national or international laws or regulations intended to limit greenhouse gas emissions, which could impact the prices of hydrocarbons; and
(vi) |  | success in developing and applying new technology.

All these factors can affect the global balance between demand and supply for oil and prices of oil. Such factors can also affect the prices of natural gas because natural gas prices for the major part of our supplies are typically indexed to the prices of crude oil and certain refined petroleum products.

Furthermore, lower oil and gas prices over prolonged periods may also adversely affect Eni’s results of operations and cash flow by: (i) reducing rates of return of development projects either planned or being implemented, leading the Company to reschedule, postpone or cancel development projects, or accept a lower rate of return on such projects; (ii) reducing the Group’s liquidity, entailing lower resources to fund expansion projects, further dampening the Company’s ability to grow future production and revenues; and (iii) triggering a review of future recoverability of the Company’s carrying amounts of oil and gas properties, which could lead to the recognition of significant impairments charges.

> Uncertainties in Estimates of Oil and Natural Gas Reserves

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 proved reserve estimates depends on a number of factors, assumptions and variables, among which the most important are the following:

• |  | the quality of available geological, technical and economic data and their interpretation and judgment;
• |  | projections regarding future rates of production and timing of development expenditures;
• |  | whether the prevailing tax rules, other government regulations and contractual conditions will remain the same as on the date estimates are made;
• |  | results of drilling, testing and the actual production performance of Eni’s reservoirs after the date of the estimates which may require substantial upward or downward revisions; and

9

##### Table of Contents

• |  | changes in oil and natural gas prices which could affect the quantities of Eni’s proved reserves since the estimates of reserves are based on prices and costs existing as of the date when those estimates are made. In particular the reserves estimates are subject to revisions as prices fluctuate due to the cost recovery mechanism under the Company’s PSAs and similar contractual schemes.

Many of these factors, assumptions and variables involved in estimating proved reserves are beyond Eni’s control and may change over time and impact the estimates of oil and natural gas reserves. Accordingly, the estimated reserves could be significantly different from the quantities of oil and natural gas that will ultimately be recovered. Additionally, any downward revision in Eni’s estimated quantities of proved reserves would indicate lower future production volumes, which could adversely impact Eni’s results of operations and financial condition.

> Oil and gas activity may be subject to increasingly high levels of income taxes

The oil and gas industry is subject to the payment of royalties and income taxes which tend to be higher than those payable in many other commercial activities. In addition, in recent years, Eni has experienced adverse changes in the tax regimes applicable to oil and gas operations in a number of countries where the Company conducts its upstream operations. As a result of those trends, management estimates that the tax rate applicable to the Company’s oil and gas operations is materially higher than the Italian statutory tax rate of 38%. In 2010, management estimates that the tax rate of the Company’s Exploration & Production segment was approximately 60%.

Management believes that the marginal tax rate in the oil and gas industry tends to increase in correlation with higher oil prices which could make it difficult for Eni to translate higher oil prices into increased net profit. However, the Company does not expect that the marginal tax rate will decrease in response to falling oil prices. Adverse changes in the tax rate applicable to the Group profit before income taxes in its oil and gas operations would have a negative impact on Eni’s future results of operations and cash flows.

> Political Considerations

> A substantial portion of our oil and gas reserves and gas supplies are located in politically, socially and economically unstable countries where we are exposed to material disruptions to our operations

Substantial portions of Eni’s hydrocarbon reserves are located in countries outside the EU and North America, some of which may be politically or economically less stable than EU or North American countries. As of December 31, 2010, approximately 80% of Eni’s proved hydrocarbon 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 2010, approximately 60% of Eni’s supplies of natural gas came from such countries. See "Item 4 – Gas & Power – Natural Gas Supplies". Adverse political, social and economic developments in any of those countries may affect Eni’s ability to continue operating in an economic way, either temporarily or permanently, and Eni’s ability to access oil and gas reserves. Particularly Eni faces risks in connection with the following issues:

(i) |  | lack of well-established and reliable legal systems and uncertainties surrounding enforcement of contractual rights;
(ii) |  | unfavorable developments in laws, regulations and contractual arrangements leading, for example, to expropriations or forced divestitures of assets and unilateral cancellation or modification of contractual terms.
|  | Eni is facing increasing competition from state-owned oil companies who are partnering Eni in a number of oil and gas projects and properties in the host countries where Eni conducts its upstream operations. These state-owned oil companies can change contractual terms and other conditions of oil and gas projects in order to obtain a larger profit share from a given project, thereby reducing Eni’s profit share. For example, Sonatrach, the Algerian national oil company, is seeking to modify the contractual terms of certain PSAs in which Eni is a party to achieve a redistribution of the tax burden of such PSAs. Sonatrach alleges that it is currently bearing part of the tax burden attributable to Eni following the enactment of certain modifications to the country’s tax regime. In case those negotiations result in a negative outcome for Eni, the future profitability of certain of Eni’s PSAs in Algeria will be reduced. For more information on this matter see "Item 4 – Exploration & Production – Algeria".
|  | Furthermore, as of the balance sheet date receivables for euro 482 million relating cost recovery under a petroleum contract in a non-OECD country were the subject of an arbitration proceeding. Similar issues are also being experienced in Kazakhstan where there is a dispute in relation to certain unresolved items of expenditure incurred by the operating company Karachaganak Petroleum Operating BV which has led to the Kazakh Authorities making certain claims against the company on the base of audits performed relating to prior years 2003-2007. Parties are negotiating in order to settle the dispute;
(iii) |  | restrictions on exploration, production, imports and exports;
(iv) |  | tax or royalty increases (including retroactive claims); and

10

##### Table of Contents

(v) |  | civil and social unrest leading to sabotages, acts of violence and incidents.

See "Item 4 – Exploration & Production – Oil and Natural Gas Reserves". While the occurrence of those events is unpredictable, it is likely that the occurrence of such events could cause Eni to incur material losses or facility disruptions, by this way adversely impacting Eni’s results of operations and cash flows.

> Risks associated with continuing political instability in North Africa and Middle East

In recent months, several North African and Middle Eastern oil producing countries have experienced and continue to experience an extreme level of political instability that has resulted in changes in governments, unrest and violence and consequential economic disruptions. Further material changes are likely but largely unpredictable. Such instability is affecting, in particular, Libya. In 2010, approximately 15% of Eni’s production originated from Libya and a material amount of Eni’s proved reserves were located in Libya. Following suspension of activities at several of Eni’s producing sites in Libya and the closure of the GreenStream pipeline transporting gas from Libya to Italy, Eni’s production in Libya as of end of March 2011, was flowing at a rate ranging from 70 to 75 KBOE/d compared to an expected level for 2011 of approximately 280 KBOE/d. Production is continuing to decline. Closure of the GreenStream pipeline has also been impacting our gas sales in the Gas & Power Division. The majority of Eni’s employees in Libya have left the country. Due to the outbreak of political unrest in Libya, in February and March 2011, the US, the UN, the EU and several countries implemented certain sanctions in relation to Libya. Future developments in Libya, which we are currently unable to predict, may have a material adverse effect on Eni’s financial condition, results of operations and Libyan assets. Please see Item 4 for additional details of our operations in Libya and the impact of recent developments on our operations.

> Our activities in Iran could lead to sanctions under relevant U.S. legislation

Eni is currently conducting oil and gas operations in Iran. The legislation and other regulations of the USA that target Iran and persons who have certain dealings with Iran may lead to the imposition of sanctions on any persons doing business in Iran or with Iranian counterparties.

The USA enacted the Iran Sanctions Act of 1996 (as amended, "ISA"), which required the President of the USA to impose sanctions against any entity that is determined to have engaged in certain activities, including investment in Iran’s petroleum sector. The ISA was amended in July 2010 by the Comprehensive Iran Sanctions, Accountability and Divestment Act of 2010 ("CISADA"). As a result, in addition to sanctions for knowingly investing in Iran’s petroleum sector, parties engaging in business activities in Iran now may be sanctioned under the ISA for knowingly providing to Iran refined petroleum products, and for knowingly providing to Iran goods, services, technology, information or support that could directly and significantly either (i) facilitate the maintenance or expansion of Iran’s domestic production of refined petroleum products, or (ii) contribute to the enhancement of Iran’s ability to import refined petroleum products. CISADA also expanded the menu of sanctions available to the President of the USA by three, from six to nine, and requires the President to impose three of the nine sanctions, as opposed to two of six, if the President has determined that a party has engaged in sanctionable conduct. The new sanctions include a prohibition on transactions in foreign exchange by the sanctioned company, a prohibition of any transfers of credit or payments between, by, through or to any financial institution to the extent the interest of a sanctioned company is involved, and a requirement to "block" or "freeze" any property of the sanctioned company that is subject to the jurisdiction of the USA. Investments in the petroleum sector that commenced prior to the adoption of CISADA appear to remain subject to the pre-amended version of the ISA, except for the mandatory investigation requirements described below, but no definitive guidance has been given. The new sanctions added by CISADA would be available to the President with respect to new investments in the petroleum sector or any other sanctionable activity occurring on or after July 1, 2010.

CISADA also adopted measures designed to reduce the President’s discretion in enforcement under the ISA, including a requirement for the President to undertake an investigation upon being presented with credible evidence that a person is engaged in sanctionable activity. CISADA also added to the ISA provisions that an investigation need not be initiated, and may be terminated once begun, if the President certifies in writing to the U.S. Congress that the person whose activities in Iran were the basis for the investigation is no longer engaging in those activities or has taken significant steps toward stopping the activities, and that the President has received reliable assurances that the person will not knowingly engage in any sanctionable activity in the future. The President also may waive sanctions, subject to certain conditions and limitations.

The USA maintains broad and comprehensive economic sanctions targeting Iran that are administrated by the U.S. Treasury Department’s Office of Foreign Assets Control ("OFAC sanctions"). These sanctions generally restrict the dealings of U.S. citizens and persons subject to the jurisdiction of the USA. In addition, we are aware of initiatives by certain U.S. states and U.S. institutional investors, such as pension funds, to adopt or consider adopting

11

##### Table of Contents

laws, regulations or policies requiring divestment from, or reporting of interests in, companies that do business with countries designated as states sponsoring terrorism. CISADA specifically authorized certain state and local Iran-related divestment initiatives. If our operations in Iran are determined to fall within the scope of divestment laws or policies, sales resulting from such divestment laws and policies, if significant, could have an adverse effect on our share price. Even if our activities in and with respect to Iran do not subject us to sanctions or divestment, companies with investments in the oil and gas sectors in Iran may suffer reputational harm as a result of increased international scrutiny.

Other sanctions programs have been adopted by various governments and regulators with respect to Iran, including a series of resolutions from the United Nations Security Council, and measures imposed by various countries based on and to implement these United Nations Security Council resolutions. On July 26, 2010, the European Union adopted new restrictive measures regarding Iran (referred to as the "EU measures"). Among other things, the supply of equipment and technology in the following sectors of the oil and gas industry in Iran are prohibited: refining, liquefied natural gas, exploration and production. The prohibition extends to technical assistance, training and financing and financial assistance in connection with such items. Extension of loans or credit to, acquisition of shares in, entry into joint ventures with or other participation in enterprises in Iran (or Iranian-owned enterprises outside of Iran) engaged in any of the targeted sectors also is prohibited.

Eni Exploration & Production Division has been operating in Iran for several years under four Service Contracts (South Pars, Darquain, Dorood and Balal, these latter two projects being operated by another international oil company) entered into with the National Iranian Oil Co (NIOC) between 1999 and 2001, and no other exploration and development contracts have been entered into since then. Under such Service Contracts, Eni has carried out development operations in respect of certain oil fields, and is entitled to recovery of expenditures made, as well as a service fee. The service contracts do not provide for payments to be made by Eni, as contractor, to the Iranian Government (e.g. leasing fees, bonuses, significant amounts of local taxes); all material future cash flows relate to the payment to Eni of its dues. All projects mentioned above have been completed or substantially completed; the last one, the Darquain project, is in the process of final commissioning and is being handed over to the NIOC. Eni Exploration & Production projects in Iran are currently in the cost recovery phase. Therefore, Eni has ceased making any further investment in the country and is not planning to make additional capital expenditures in Iran in any year subsequent to 2010. Eni’s other significant involvement in Iran is that, from time to time, Eni may purchase Iranian-origin crude oil. Eni has no involvement in Iran’s refined petroleum sector, and does not export refined petroleum to Iran. In addition, we have occasionally entered into licensing agreement with certain Iranian counterparties for the supply of technologies in the petrochemical sector. In 2010, Eni’s production in Iran averaged 21 KBOE/d, representing approximately 1% of the Eni Group’s total production for the year. Eni’s entitlement in 2010 represented less than 10% of the overall production from the oil and gas fields that we have developed in Iran. Eni does not believe that the results from its Iranian activities have or will have a material impact on the Eni Group’s results.

After passage of CISADA, Eni engaged in discussions with officials of the U.S. State Department, which administers the ISA, regarding Eni’s activities in Iran. On September 30, 2010, the U.S. State Department announced that the U.S. Government, pursuant to a provision of the ISA added by CISADA that allows it to avoid making a determination of sanctionability under the ISA with respect to any party that provides certain assurances, would not make such a determination with respect to Eni based on Eni’s commitment to end its investments in Iran’s energy sector and not to undertake new energy-related activity. The U.S. State Department further indicated at that time that, as long as Eni acts in accordance with these commitments, we will not be regarded as a company of concern for our past Iran-related activities.

With respect to segments other than Exploration & Production, our Refining & Marketing segment has historically purchased amounts of Iranian crude oil under a term contract with the NIOC and on a spot basis. We purchased 1.42 mmtonnes, 980 ktonnes and 1.63 mmtonnes in 2008, 2009 and 2010, respectively. We paid NIOC $953 million in 2008, $419 million in 2009 and $888 million in 2010 for those purchases.

In addition in the three-year period 2008-2010 we purchased crude oil from international traders and oil companies who, based on bills of loading and shipping documentation available to us, we believe purchased the crude oil from Iranian companies. Purchases were mainly on spot basis. In 2008, we purchased 1.3 mmtonnes of crude oil amounting to $830 million; in 2009, we purchased 278 ktonnes of crude oil amounting to $147 million and in 2010, we purchased 2.09 mmtonnes of crude oil amounting to $1.1 billion.

We will continue to monitor closely legislative and other developments in the USA and the European Union in order to determine whether our remaining interests in Iran could subject us to application of either current or future sanctions under the OFAC sanctions, the ISA, the EU Measures or otherwise. If any of our activities in and with respect to Iran are found to be in violation of any Iran-related sanctions, and sanctions are imposed on Eni, it could have an adverse effect on our business, plans to raise financing, sales and reputation.

> We have commercial transactions with Syria where we mainly purchase from time to time volumes of crude oil

Our operations in Syria have mainly been limited to transactions carried out by our Refining & Marketing Division with Syrian Petrol Company, an entity controlled by the Syrian Government, for the purchase of crude oil under term purchase contracts or on a spot basis, based on prevailing market conditions.

We purchased 329 ktonnes, 241 ktonnes and 321 ktonnes in 2008, 2009 and 2010, respectively. We paid Syrian Petrol Company $227 million in 2008, $92 million in 2009 and $163 million in 2010 for those purchases.

In 2008, we also purchased 184 ktonnes of crude oil amounting to $73 million and in 2010 we purchased 115 ktonnes of crude oil amounting to $59 million, in each case from international traders who, based on bills of loading and shipping documentation available to us, we believe purchased those raw materials from Syrian companies.

Other than as described above, Eni is not currently investing in the country, and it has no contractual arrangements in place to invest in the country. However, we have recently been exploring investment opportunities in Syria.

> Cyclicality of the Petrochemical Industry

The petrochemical industry is subject to cyclical fluctuations in demand in response to economic cycles, with consequential effects on prices and profitability exacerbated by the highly competitive environment of this industry. Eni’s petrochemical operations have been in the past and may be adversely affected in the future by worldwide economic slowdowns, intense competitive pressures and excess installed production capacity. Furthermore, Eni’s petrochemical operations face increasing competition from Asian companies and national oil companies’ petrochemical divisions which can leverage on long-term competitive advantages in terms of lower operating costs and feedstock purchase costs. Particularly, Eni’s petrochemical operations are located mainly in Italy and Western Europe where the regulatory framework and public environmental sensitivity are generally more stringent than in other countries, especially Far East countries, resulting in higher operating costs of our petrochemical operation compared to the Company’s Asiatic competitors due to the need to comply with applicable laws and regulations in environmental and other related matters. Additionally, our petrochemical operations lack sufficient scale and competitiveness in a number of sites. Due to weak industry fundamentals, intense competitive pressures and high feedstock costs, our petrochemicals operations incurred substantial operating losses in both 2009 and 2008 of euro 675 million and euro 845 million, respectively. However, results in 2010 improved substantially and operating loss diminished to euro 86 million due to demand recovery, cost efficiencies and better unit margins, while the overall profitability was impaired by higher oil-based feedstock costs. Looking forward, management expects that while any strengthening in the global recovery may benefit demand for our products, continuing increases in the cost of oil represent a risk to the profitability of the Company’s petrochemicals operation as it may be difficult transferring higher feedstock costs to end-prices of products due to the high level of competition in the industry and the commoditized nature of many of Eni’s products.

> Risks in the Company Gas & Power business segment

> i) Risks associated with the Trading Environment and Competition in the Industry

> In 2010, the Company’s results of operations and cash flow were negatively affected by lower sales volumes and reduced unit margins due to increasing competitive pressures arising from large gas availability on the marketplace. We expect continuing competitive pressures and oversupply to affect our results in 2011 and beyond

In 2010, gas demand in Italy and Europe rebounded from the depressed levels registered in the previous year, growing by 6% and 4%, respectively. Consumption volumes, however, remained below the pre-crisis levels seen in 2007. The Eni gas business failed to benefit from demand growth in 2010 as sales volumes declined by 6.4% from 2009 with Italy posting the largest decrease, with direct sales to customers down by 14.4% and sales to importers to Italy down by 19.5% driven by rising competitive pressures which also dragged down unit selling margins on gas sales in Italy. The Company’s results in its European markets business unit were affected by lowering average gas selling margins as gas spot prices at continental hubs were dragged down by large availability of LNG and competitive pressures. While spot prices have increasingly been adopted as contractual benchmarks in selling formulae outside Italy, the Company’s cost of supplies remained linked to trends in oil prices as provided by its long-term contractual arrangements to purchase gas from suppliers. As a result the Company’s unit margins outside Italy fell sharply in 2010. Management believes that those trends will continue weighing on the gas business’ future results of operations and cash flows over the next three years.

> A recovery in profitability of the Company’s marketing business depends heavily on the management’s assumption to be able to renegotiate better contractual terms within the Company’s long-term gas supply contracts

The industrial and financial forecasts for the next four-year plan of the gas business as well as the amount of the impairment loss recognized in 2010 Consolidated Financial Statements both take into consideration management assumptions that the Company’s long-term gas purchase contracts will be renegotiated at better economic terms for Eni, so as to restore the competitiveness of the Company’s cost position in the current depressed scenario for the gas sector. The renegotiation of revised contractual terms, including any price revisions and contractual flexibility, is established by such contractual clauses whereby parties are held to bring the contract back to the economic equilibrium in case of significant changes in the market environment, like the ones that have been occurring since the second half 2008. In the course of 2010, Eni has finalized a number of important contractual renegotiations by obtaining improved economic conditions for supplies and wider contractual flexibility with a benefit to its commercial programs. A number of renegotiations have been commenced or are due to commence in the upcoming months involving all the Company’s main suppliers of gas based on long-term contracts. Should the outcome of those renegotiations fall short of management’s expectations and absent a solid recovery in fundamentals of the gas sector, management believes that future results of operations and cash flows of the Company’s gas business will be negatively affected with further consequences in terms of recoverability of the carrying amounts of the gas business assets. In 2010 Consolidated Financial Statements, the Company recorded an impairment loss of euro 425 million related to its goodwill in the European gas business; for further information see "Item 5 – Operating and Financial Review and Prospects – Group Results of Operations".

> We expect that current imbalances between demand and supply in the European gas market will persist for sometime

Management estimates that long-term demand growth will achieve an average rate of 1.7% and 1.1% in Italy and Europe, respectively, until 2020. Those estimates have been revised down from previous management projections to factor in the expected impacts associated with a number of ongoing trends:

• |  | uncertainties and volatility in the current macroeconomic cycle;
• |  | growing adoption of consumption patterns and life-style characterized by wider sensitivity to energy efficiency;
• |  | EU policies intend to reducing GHG emissions and promoting renewable energy source. For further information about the Company’s outlook for gas demand see "Item 4 – Gas & Power".

The projected moderate dynamics in demand development will not be sufficient to balance current oversupplies on the marketplace over the next three years according to management’s estimates. Gas oversupplies have been increasing in recent years as new, large investments to upgrade import pipelines to Europe have come online from Russia, Libya and Algeria, and large availability of LNG on a worldwide scale has found an outlet at the European continental hubs driving the development of very liquid spot gas markets. Also, certain Eni’s competitors are currently assessing the economic feasibility of new gas import infrastructures, targeting 5-10 BCM of capacity expansion online from 2015-2016 according to management’s assumptions.

Management believes that a better balance between demand and supply will not be achieved until 2014, at the earliest. Those trends represent risks to the Company’s future results of operations and cash flows in its gas business.

> Current, negative trends in gas demands and supplies may impair the Company’s ability to fulfill its minimum off-take obligations in connection with its take-or-pay, long-term gas supply contracts

In order to secure long-term access to gas availability, particularly with a view of supplying the Italian gas market, Eni has signed a number of long-term gas supply contracts with key producing countries that supply the European gas markets. Those contracts have been ensuring approximately 80 BCM of gas availability from 2010 (including the Distrigas portfolio of supplies) with a residual life of approximately 19 years and a pricing mechanism indexed to the price of crude oil and its derivatives (gasoil, fuel oil, etc.). The contracts provide take-or-pay clauses whereby the Company is required to collect minimum pre-determined volumes of gas in each year of the contractual term or, in case of failure, to pay the whole price, or a fraction of that price, applied to uncollected volumes up to the minimum contractual quantity. The take-or-pay clause entitles the Company to collect pre-paid volumes of gas in later years during the period of contract execution. Amounts of cash pre-payments and time schedules for collecting pre-paid gas vary from contract to contract. Generally, cash pre-payments are calculated on the basis of the energy prices current in the year of non-fulfillment with the balance due in the year when the gas is actually collected. Amounts of pre-payments range from 10 to 100 percent of the full price. The right to collect pre-paid gas expires within a ten-year term in some contracts or remains in place until contract expiration in other arrangements. In addition, rights to collect pre-paid gas in future years can be exercised provided that the Company

has fulfilled its minimum take obligation in a given year and within the limit of the maximum annual quantity that can be collected in each contractual year. In this case, Eni will pay the residual price calculating it as the percentage that complements 100%, based on the arithmetical average of monthly base prices current in the year of the off-take. Similar considerations apply to ship-or-pay contractual obligations.

Management believes that the current outlook for moderate gas demand growth and large gas availability on the marketplace, the possible evolution of sector-specific regulation, as well as the de-coupling between trends in gas prices indexed to oil versus gas benchmark prices at spot markets, represent risks factors to the Company’s ability to fulfill its minimum take obligations associated with its long-term supply contracts.

In 2009 and 2010, Eni incurred the take-or-pay clause as the Company collected lower volumes than its minimum take obligations in each of those years accumulating deferred costs for an amount of euro 1.44 billion as of December 31, 2010. The Company’s ability to recover those pre-paid volumes within contractual terms will depend in future years on a number of factors, including the possible evolution of the market environment and the competitiveness of Eni’s cost position, with this latter being influenced by the Company’s ability to renegotiate better contractual terms of its long-term purchase contracts (see paragraph above).

In case Eni fails to off-take the contractual minimum amounts, it will be exposed to a price risk, because the purchase price Eni will ultimately be required to pay is based on prices prevailing after the date on which the off-take obligation arose. In addition, Eni is subject to the risk of not being able to dispose of pre-paid volumes. The Company also expects to incur financing costs to pay cash advances corresponding to contractual minimum amounts. As a result, the Company’s selling margins, results of operations and cash flow may be negatively affected.

For further information on the Company’s take-or-pay contracts see "Item 4 – Gas & Power – Purchases".

> Eni plans to increase natural gas sales in Europe. If Eni fails to achieve projected growth targets, this could adversely impact future results of operations and liquidity

Over the medium-term, Eni plans to increase its natural gas sales in Europe leveraging on its natural gas availability under take-or-pay purchase contracts, availability of transport rights and storage capacity, and widespread commercial presence in Europe which benefited from synergies from integrating the Belgian gas operator Distrigas acquired in 2009. Should Eni fail to increase natural gas sales in Europe as planned due to poor strategy execution or competition, Eni’s future growth prospects, results of operations and cash flows might be adversely affected also taking account that Eni might be unable to fulfill its contractual obligations to purchase certain minimum amounts of natural gas based on its take-or-pay purchase contracts currently in force.

> ii) Risks associated with sector-specific regulations in Italy

> The natural gas market in Italy is highly regulated in order to favor the opening of the market and development of competition

In 2010, the regulated period for gas antitrust thresholds defined by Legislative Decree No. 164 of May 23, 2000 expired. Those thresholds defined maximum allowed limits of gas volumes (imported or domestically produced) input into the national transport network and marketed to final customers, applicable to each operator.

That system of antitrust thresholds was replaced with a mechanism of market shares enacted by Legislative Decree No. 130 of August 13, 2010. The Decree introduced a 40% ceiling to the wholesale market share of each Italian gas operator. This ceiling can be raised to 55.9% in case an operator commits itself to building new storage capacity in Italy for a total of 4 BCM within five years. The new capacity shall be allocated to industrial and power generation customers. In case of breaching the mandatory thresholds, an operator is obliged to execute gas release measures at regulated prices. Eni plans to build new storage capacity and, in the meantime, intends to adopt measures and bear the associated expenses to make 50% of that planned capacity available to requesting customers (for further information see "Operating Review of the Gas & Power Division – Paragraph Regulation"). Eni believes that this new gas regulation will increase competitiveness in the wholesale natural gas market in Italy.

Further material aspects regarding the Italian gas sector regulations are regulated access to infrastructures (transport backbones, storage fields, distribution networks and LNG terminals), the unbundling of activities relating to infrastructures within vertically-integrated group companies, from July 1, 2008 (as defined by Decision No. 11/2007 and updated by Resolution No. 253/2007 of the Authority for Electricity and Gas). Also the Italian Authority for Electricity and Gas is entrusted with certain powers in the matters of setting tariffs for transport, distribution, storage and re-gasification services, as well as in approving specific codes for each regulated activity,

monitoring natural gas prices and setting pricing mechanisms for supplies to residential users consuming less than 200,000 CM/y. See next paragraph.

> Risks associated with the regulatory powers entrusted to the Italian Authority for Electricity and Gas in the matter of pricing to residential customers

The Authority for Electricity and Gas is entrusted with certain powers in the matters of natural gas pricing. Specifically, the Authority for Electricity and Gas holds a general surveillance power on pricing in the natural gas market in Italy and the power to establish selling tariffs for the supply of natural gas to residential and commercial users consuming less than 200,000 CM/y (qualified as non eligible customers as of December 31, 2002 as defined by Legislative Decree No. 164/2000) taking into account the public goal of containing the inflationary pressure due to rising energy costs. Accordingly, decisions of the Authority for Electricity and Gas on these matters may limit the ability of Eni to pass an increase in the cost of the raw material onto final consumers of natural gas. The indexation mechanism set by the Authority for Electricity and Gas with Resolution No. 64/2009 basically provides that the cost of the raw material in pricing formulae to the residential sector be indexed to movements in a basket of hydrocarbons. In 2010, the Authority for Electricity and Gas with Resolution ARG/gas 89/10 amended that indexation mechanism and established a fixed reduction of 7.5% of the raw material cost component in the final price of supplies to residential users be applied in the thermal year October 1, 2010-September 30, 2011. This resolution will negatively affect Eni’s future results of operations and cash flows, considering the negative impact on unit margins in sales to residential customers. Administrative appeals against the Authority’s resolution, which have been filed by many operators including Eni, might possibly impact that matter.

Management cannot exclude the possibility that in the future the Authority for Electricity and Gas could implement further measures in this matter which may negatively affect Eni results of operations and liquidity.

> Due to the regulated access to natural gas transport infrastructures in Italy, Eni may not be able to sell in Italy all the natural gas volumes it planned to import and, as a consequence, the Company may be unable to sell all the natural gas volumes which it is committed to purchase under take-or-pay contract obligations

Other risk factors deriving from the regulatory framework are associated with regulation of the access to the Italian gas transport network that is currently set by Decision No. 137/2002 of the Authority for Electricity and Gas. The decision is fully-incorporated into the network code presently in force as prepared by the system’s operator. The decision sets priority criteria for transport capacity entitlements at points where the Italian transport network connects with international import pipelines (the so-called entry points to the Italian transport system). Specifically, operators that are party to take-or-pay contracts, as in the case of Eni, are entitled to a priority in allocating available transport capacity within the limit of average daily contractual volumes. Gas volumes exceeding average daily contractual volumes are not entitled to any priority and, in case of congestion at any entry points, they are entitled available capacity on a proportionate basis together with all pending requests for capacity assignments. Under its take-or-pay purchase contracts, Eni may off-take daily volumes in excess of average daily contractual volumes. This flexibility is important to Eni’s commercial programs as it is used when demand peaks, usually during the wintertime. In the event congestion occurs at entry points to the Italian transport network, based on current regulations, available transport capacity would be entitled firstly to operators having a priority right, i.e. holders of take-or-pay contracts within the limits of average daily contractual volumes. Then any residual available transport capacity would be allocated in proportion to all pending capacity requests. Eni believes that Decision No. 137/2002 is in contrast with the rationale of the European regulatory framework on the gas market as provided in European Directive No. 2003/55/EC. The Company, based on that belief, has commenced an administrative procedure to repeal Decision No. 137/2002 before an administrative court which recently confirmed in part Eni’s position. An administrative appeals court also confirmed the Company’s position. Specifically, the Court stated that the purchase of the contractual flexibility is an obligation on part of the importer, which responds to a collective interest. According to the Court, there is no reasonable motivation whereby volumes corresponding to such contractual flexibility should not be granted priority in access to the network, also in case congestion occurs. At the moment, however, no case of congestion occurred at entry points to the Italian transport infrastructure such to impairing Eni’s marketing plans.

Management believes that Eni’s results of operations and cash flows could be adversely affected should a combination of market conditions and regulatory constraints prevent Eni from fulfilling its minimum take contract obligations. See "Item 5 – Outlook".

> A number of mandatory gas release measures and other administrative measures have been recently implemented in Italy resulting in a negative impact on Eni’s results of operations and liquidity. It is possible that similar measures will be implemented in future years

Gas release measures are administrative acts whereby Eni is obliged to dispose of certain amounts of gas at set prices and conditions as provided in the relevant gas release measure. Those measures are intended to increase flexibility and liquidity in the gas market. This measure strongly affected Eni’s marketing activity in Italy. In 2007, Eni agreed to adhere to a gas release program involving 4 BCM which were disposed of in a two-year period (from October 1, 2007 to September 30, 2009). For thermal year 2009/2010 Italian Law No. 99/2009 obliged Eni to dispose of 5 BCM of gas in yearly and half-yearly amounts. Although the allotment procedure (bid) was based on a minimum price set by the Ministry for Economic Development, only 1.1 BCM were awarded out of the planned 5 BCM. The price set by the Ministry was lower than the average price of Eni’s sales in Italy.

For the next few years, based on indications made by the AEEG (in a report to the Parliament on the situation of the gas and electricity market in Italy as provided in Resolution PAS 3/2010), Eni cannot exclude the possibility that the Company may be obliged to implement new gas release programs. As a consequence, future results and cash flows could be negatively affected.

In 2010, a national trading platform was implemented where gas importers must trade volumes of gas corresponding to a legal obligation on part of Italian importers and producers. Under those provisions, importers from extra-EU countries are required to supply a set percentage of imported volumes in a given thermal year and to trade them at the national trading platform on a spot basis. Fulfillment of that obligation is a condition for the importer to be permitted to import gas from extra-EU countries. Also royalties in-kind owed to the Italian State on gas production are to be traded on that trading platform. The new trading platform is expected to develop a spot market for natural gas in Italy.

> The Italian Government, Parliament and the regulatory authorities in Italy and in Europe may take further steps to increase competition in the Italian natural gas market and such regulatory developments may adversely affect Eni’s results of operations and cash flows

Italian administrative and governmental institutions and political forces are urging a higher degree of competition in the Italian natural gas market and this may produce significant developments in this area.

In 2003, Law No. 290 was enacted in Italy which prohibits Eni from holding an interest higher than 20% in undertakings owning natural gas transport infrastructures in Italy (Eni currently holds a 52.54% interest in Snam Rete Gas). A decree is expected to be enacted by the Italian Prime Minister to establish the relevant provisions to implement this mandatory disposal. The deadline for the disposal, which was initially scheduled for December 31, 2008, is to be rescheduled in a 24-month deadline following enactment of the decree from the Italian Prime Minister. Currently, Eni is unable to predict any development of this matter.

In recent years, both the Italian Authority for Electricity and Gas and the Italian Antitrust Authority (the "Antitrust Authority") have conducted several reviews and inquiries on the status of Italian natural gas market, targeting the overall level of competition, the degree of opening to competition of the residential sector, levels of entry-exit barriers, and other areas such as sub-investment in the storage sector. Both the Authority for Electricity and Gas and the Antitrust Authority believe that the vertical integration of Eni in the supply, transport, distribution, storage and marketing of gas may hamper development of a competitive gas market in Italy.

Management believes the institutional debate on the degree of competition in the Italian natural gas market and the regulatory activity to be areas of attention and cannot exclude negative impacts deriving from developments on these matters on Eni’s future results of operations and cash flows.

For more information on these issues see "Item 4 – Regulation – Gas & Power".

> Antitrust and competition law

The Group’s activities are subject to antitrust and competition laws and regulations in many countries of operations, especially in Europe. In the years prior to 2008, Eni recorded significant loss provisions due to unfavorable developments in certain antitrust proceedings before the Italian Antitrust Authority, and the European Commission. It is possible that the Group may incur significant loss provisions in future years relating ongoing antitrust proceedings or new proceedings that may possibly arise. The Group is particularly exposed to this risk in its natural gas and refining and marketing activities due to the fact that Eni is the incumbent operator in those markets in Italy and a large European gas player. See Note 34 to the Consolidated Financial Statements for a full description of Eni’s main pending antitrust proceedings.

##### Table of Contents

Furthermore, based on the findings of antitrust proceedings, plaintiffs could seek payment to compensate for any alleged damages as a result of antitrust business practices on part of Eni. Both these risks could adversely affect the Group’s future results of operations and cash flows.

> Environmental, Health and Safety Regulation

> Eni may incur material operating expenses and expenditures in relation to compliance with applicable environmental, health and safety regulations

Eni is subject to numerous EU, international, national, regional and local environmental, health and safety laws and regulations concerning its oil and gas operations, products and other activities. Generally, 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, as well as refining, petrochemicals and other Group operations, limit or prohibit drilling activities in certain protected areas, provide for measures to be taken to protect the safety of the workplace and health of communities involved by the Company’s activities, and impose criminal or civil liabilities for polluting the environment or harming employees or communities health and safety resulting from oil, natural gas, refining, petrochemical and other Group’s operations.

These laws and regulations also regulate emissions of substances and pollutants, handling of hazardous materials and discharges to surface and subsurface water resulting from the operation of oil and natural gas extraction and processing plants, petrochemical plants, refineries, service stations, vessels, oil carriers, pipeline systems and other facilities owned by Eni. In addition, Eni’s operations are subject to laws and regulations relating to the production, handling, transportation, storage, disposal and treatment of waste materials. In 2009, new regulations were enacted in Italy relating to monitoring the route of waste from production up to its disposal/recycling, also prosecuting any unlawful conducts. The Company anticipates that it will incur operating costs to comply with this new regulation in 2011 when the new system of monitoring waste becomes fully-operational. Breach of environmental, health and safety laws exposes the Company’s employees to criminal and civil liability and the Company to the incurrence of liabilities associated with compensation for environment health or safety damage. Additionally, in the case of violation of certain rules regarding safety in the workplace, the Company can be liable as provided for by a general EU rule on businesses liability due to negligent or willful conduct on part of their employees as adopted in Italy with Law Decree No. 231/2001.

Environmental, health and safety laws and regulations have a substantial impact on Eni’s operations. Management expects that the Group will continue to incur significant amounts of operating expenses and expenditures to comply with environmental, health and safety laws and regulations, also taking into account possible future developments in environmental regulations in Italy and in other countries where Eni operates, particularly current and proposed fuel and product specifications, emission controls and implementation of increasingly strict measures decided at both international and country level to reduce greenhouse gas emissions. For more discussion about this latter topic see "Item 4 – Environmental Regulations".

> Eni has incurred in the past and may incur in the future material environmental liabilities in connection to the environmental impact of its past and present industrial activities. Also plaintiffs may seek to obtain compensation for damage resulting from events of contamination and pollution

Risks of environmental, health and safety incidences and liabilities are inherent in many of Eni’s operations and products. Notwithstanding management’s beliefs that Eni adopts high operational standards to ensure safety of its operations and to protect the environment and health of people and employees, it is possible that incidents like blow-outs, oil spills, contaminations and similar events could occur that would result in damage to the environment, employees and communities. Environmental laws also require the Company to remediate and clean-up the environmental impacts of prior disposals or releases of chemicals or petroleum substances and pollutants by the Company. Such contingent liabilities may exist for various sites that the Company disposed of, closed or shut down in prior years where the Group products have been produced, processed, stored, distributed or sold, such as chemicals plants, mineral-metallurgic plants, refineries and other facilities. The Company is particularly exposed to the risk of environmental liabilities in Italy where the vast majority of the Group industrial installations are localized and also due to the circumstance that the Group engaged in a number of industrial activities in past years that were subsequently divested, closed, liquidated or shut down. At those industrial sites Eni has commenced in recent years a number of remedial plans to restore and clean-up proprietary or concession areas that were contaminated and polluted by the Group’s industrial activities in previous years. Notwithstanding the Group claimed that it cannot be held liable for such past contaminations as permitted by applicable regulations in case of declaration rendered by a guiltless owner – particularly regulations that enacted into Italian legislation the Directive No. 2004/35/EC – a number of civil and administrative proceedings have arisen relating to both the environmental damage and

18

##### Table of Contents

administrative prescriptions on how to perform individual cleaning-up project. In 2010, Eni proposed a global transaction to the Italian Ministry for the Environment related to nine sites of national interest where the Group has been performing clean-up activities in order to define the scope of work of each clean-up project and settle all pending administrative and civil litigation. To account for this proposal, the Group accrued a pre-tax risk provision amounting to euro 1.1 billion in its 2010 Consolidated Financial Statements.

Remedial actions with respect to other Company’s sites are expected to continue in the foreseeable future, impacting our liquidity as the Group has accrued risk provisions to cope with all existing environmental liabilities whereby both a legal or constructive obligation to perform a clean-up or other remedial actions is in place and the associated costs can be reasonably estimated. The accrued amount represents the management’s best estimates of future environmental expenses to be incurred.

Notwithstanding this, management believes that it is possible that in the future Eni may incur significant environmental expenses and liabilities in addition to the amounts already accrued due to: (i) the likelihood of as yet unknown contamination; (ii) the results of ongoing surveys or surveys to be carried out on the environmental status of certain Eni’s industrial sites as required by the applicable regulations on contaminated sites; (iii) unfavorable developments in ongoing litigation on the environmental status of certain Company’s site where a number of public administrations and the Italian Ministry for the Environment act as plaintiffs; (iv) the possibility that new litigation might arise; (v) the probability that new and stricter environmental laws might be implemented; and (vi) the circumstance that the extent and cost of future environmental restoration and remediation programs are often inherently difficult to estimate.

> Legal Proceedings

Eni is party to a number of civil actions and administrative proceedings arising in the ordinary course of business. In addition to existing provisions accrued as of the balance sheet date to account for ongoing proceedings, it is possible that in future years Eni may incur significant losses in addition to amounts already accrued in connection with pending legal proceedings due to: (i) uncertainty regarding the final outcome of each proceeding; (ii) the occurrence of new developments that management could not take into consideration when evaluating the likely outcome of each proceeding in order to accrue the risk provisions as of the date of the latest financial statements; (iii) the emergence of new evidence and information; and (iv) underestimation of probable future losses due to the circumstance that they are often inherently difficult to estimate. See disclosure of pending litigation in Note 34 to the Consolidated Financial Statements.

> Risks related to Changes in the Price of Oil, Natural Gas, Refined Products and Chemicals

Operating results in Eni’s Exploration & Production, Refining & Marketing, and Petrochemical segments are affected by changes in the price of crude oil and by the impacts of movements in crude oil prices on margins of refined and petrochemical products.

> Eni’s results of operations are affected by changes in international oil prices

Overall, lower oil prices have a net adverse impact on Eni’s results of operations. The effect of lower oil prices on Eni’s average realizations for produced oil is generally immediate. Furthermore, Eni’s average realizations for produced oil differ from the price of Brent crude marker primarily due to the circumstance that Eni’s production slate, which also includes heavy crude qualities, has a lower API gravity compared with Brent crude (when processed the latter allows for higher yields of valuable products compared to heavy crude qualities, hence higher market price).

> The favorable impact of higher oil prices on Eni’s results of operations may be offset in part by different trends in margins for Eni’s downstream businesses

The impact of changes in crude oil prices on Eni’s downstream businesses, including the Gas & Power, the Refining & Marketing and the Petrochemical businesses, depends upon the speed at which the prices of gas and products adjust to reflect movements in oil prices.

In the Gas & Power segment, increases in the oil price represent a risk to the Company as gas supplies are mainly indexed to the cost of oil and certain refined products, while selling prices, particularly outside Italy, are increasingly linked to certain market benchmarks quoted at continental hubs. In the current trading environment,

19

##### Table of Contents

spot prices at those hubs are particularly depressed due to oversupply conditions. In addition, the Italian Authority for Electricity and Gas may limit the ability of the Company to pass cost increases linked to higher oil prices onto selling prices in supplies to residential customers and small businesses as the Italian Authority for Electricity and Gas regulates the indexation mechanism of the raw material cost in selling formulae to those customers. See the paragraph "Risks in the Company’s gas business" above for more information.

In addition, in light of changes in the European gas market environment, Eni has recently adopted new risk management policies. These policies contemplate the use of derivative contracts to mitigate the exposure of Eni’s future cash flows to future changes in gas prices; such exposure had been exacerbated in recent years by the fact that spot prices at European gas hubs have ceased to track the oil prices to which Eni’s long-term supply contracts are linked. These policies also contemplate the use of derivative contracts for speculative purposes whereby Eni will seek to profit from opportunities available in the gas market based, among other things, on its expectations regarding future prices. These contracts may lead to gains as well as losses, which, in each case, may be significant. All derivative contracts that are not entered into for hedging purposes in accordance with IFRS will be accounted through profit and loss, resulting in higher volatility of the gas business’ operating profit. Please see "Item 5 – Financial Review – Outlook" and "Item 11 – Quantitative and Qualitative Disclosures About Market Risk".

In the Refining & Marketing and Petrochemical businesses a time lag exists between movements in oil prices and in prices of finished products.

> Eni’s results of operations are affected by changes in European refining margins

Results of operations of the Eni’s Refining & Marketing segment are substantially affected by changes in European refining margins which reflect changes in relative prices of crude oil and refined products. The prices of refined products depend on global and regional supply/demand balances, inventory levels, refinery operations, import/export balances and weather. Furthermore, Eni’s realized margins are also affected by relative price movements of heavy crude qualities versus light crude qualities, taking into account the ability of Eni’s refineries to process complex crudes that represent a cost advantage when market prices of heavy crudes are relatively cheaper than the marker Brent price. In 2010, Eni’s refining margins were unprofitable as the high cost of oil was only partially transferred to final prices of fuels at the pump pressured by weak demand, high worldwide and regional inventory levels and excess refining capacity. Management does not expect any significant recovery in industry fundamentals over the next four-year industrial plan. The sector as a whole will continue to suffer from weak demand and excess capacity, while the cost of oil feedstock may continue rising and price differentials may remain compressed. In this context, management expects that the Company’s refining margins will remain at below break-even levels in 2011 and possibly beyond.

> Eni’s results of operations are affected by changes in petrochemical margins

Eni’s margins on petrochemical products are affected by trends in demand for petrochemical products and movements in crude oil prices to which purchase costs of petroleum-based feedstock are indexed. Given the commoditized nature of Eni petrochemical products, it is difficult for the Company to transfer higher purchase costs for oil-based feedstock to selling prices to customers. Rising oil-based feedstock costs will continue to negatively affect Eni’s results of operations and liquidity in this business segment in 2011.

> Risks from Acquisitions

Eni constantly monitors the oil and gas market in search of opportunities to acquire individual assets or companies in order to achieve its growth targets or complement its asset portfolio. Acquisitions entail an execution risk – an important risk, among other matters, that the acquirer will not be able to effectively integrate the purchased assets so as to achieve expected synergies. In addition, acquisitions entail a financial risk – the risk of not being able to recover the purchase costs of acquired assets, in case a prolonged decline in the market prices of oil and natural gas occurs. We also may incur unanticipated costs or assume unexpected liabilities and losses in connection with companies or assets we acquire. If the integration and financial risks connected to acquisitions materialize, our financial performance may be adversely affected.

20

##### Table of Contents

> Credit risk

Credit risk is the potential exposure of the Group to losses in case counterparties fail to perform or pay due amounts. Credit risks arise from both commercial partners and financial ones. In recent years, the Group has experienced a higher than normal level of counterparty failure due to the severity of the economic and financial downturn. In our 2010 Consolidated Financial Statements, we accrued an allowance against doubtful accounts amounting to euro 201 million, mainly relating the Gas & Power business. Management believes that the Gas & Power business is particularly exposed to credit risks due to its large and diversified customer base which include a large number of middle and small businesses and retail customers where impacts of the economic and financial downturn were particularly severe.

> Exchange Rates

Movements in the exchange rate of the euro against the U.S. dollar can have a material impact on Eni’s results of operations. Prices of oil, natural gas and refined products generally are denominated in, or linked to, U.S. dollars, while a significant portion of Eni’s expenses are denominated in euros. Similarly, prices of Eni’s petrochemical products are generally denominated in, or linked to, the euro, whereas expenses in the Petrochemical segment are denominated both in euros and U.S. dollars. Accordingly, a depreciation of the U.S. dollar against the euro generally has an adverse impact on Eni results of operations and liquidity because it reduces booked revenues by an amount greater than the decrease in U.S. dollar-denominated expenses. The Exploration & Production segment is particularly affected by movements in the U.S. dollar versus the euro exchange rates as the U.S. dollar is the functional currency of a large part of its foreign subsidiaries and therefore movements in the U.S. dollar versus the euro exchange rate affect year-on-year comparability of results of operations.

> Risks deriving from Eni’s Exposure to Weather Conditions

Significant changes in weather conditions in Italy and in the rest of Europe from year to year may affect demand for natural gas and some refined products; in colder years, demand is higher. Accordingly, the results of operations of the Gas & Power segment and, to a lesser extent, the Refining & Marketing segment, as well as the comparability of results over different periods may be affected by such changes in weather conditions.

Furthermore, our operations, particularly offshore production of oil and natural gas, are exposed to extreme weather phenomena that can result in material disruption to our operations and consequent loss or damage of properties and facilities.

> Interest Rates

Interest on Eni’s debt is primarily indexed at a spread to benchmark rates such as the Europe Interbank Offered Rate, "Euribor", and the London Interbank Offered Rate, "Libor". As a consequence, movements in interest rates can have a material impact on Eni’s finance expense in respect to its debt.

> Critical Accounting Estimates

The preparation of financial statements requires management to make certain accounting estimates that are characterized by a high degree of uncertainty, complexity and judgment. These estimates affect the reported amount of the Company’s assets and liabilities, as well as the reported amount of the Company’s income and expenses for a given period. Although management believes these estimates to represent the best outcome of the estimation process, actual results could differ from such estimates, due to, among other things, the following factors: uncertainty, lack or limited availability of information, availability of new informative elements, variations in economic conditions such as prices, costs, other significant factors including evolution in technologies, industrial practices and standards (e.g. removal technologies) and the final outcome of legal, environmental or regulatory proceedings. See "Item 5 – Critical Accounting Estimates".

> Strategy

Eni’s strategy is to expand the Company’s principal businesses over both the medium and the long-term, with improving profitability. Specifically, the Company is planning for:

• |  | growing profitably oil and gas production in the Exploration & Production business leveraging on the development of the Company’s portfolio of assets and pipeline of capital projects. The Company plansto drive higher returns by reducing the time to market of our projects, focusing on continued cost control and deploying our competencies and technologies to manage technical risks;
• |  | improving profitability in the Gas & Power business by leveraging on the Company’s assets (long-term supply contracts, transport rights, storage capacity), renegotiation of the principal long-term supply contracts to boost the competitiveness of the Company’s cost position and implementation of effective marketing initiatives against the backdrop of a challenging competitive landscape in the European gas market reflecting increasing competition and ongoing oversupply conditions;
• |  | improving profitability and cash generation in the Refining & Marketing business in the face of weak industry fundamentals and a poor outlook for refining margins expected to remain below their historical averages across the plan period. Management plans to implement cost reduction initiatives, integration of refinery cycles to capture cost savings or margin expansions, and selective capital projects to upgrade refinery complexity. In the marketing business, we plan to enhance profitability through a number of initiatives for improving service quality and client retention and non-oil profit contribution;
• |  | enhancing revenues and profitability in our Engineering & Construction business by leveraging on our strong order backlog, technologically-advanced assets and competencies in engineering and project management and execution; and
• |  | managing efficiently and effectively our petrochemicals business, and re-launching development initiatives in the field of environmentally-friendly projects.

In executing this strategy, management intends to pursue integration opportunities among and within businesses and strongly focus on efficiency improvement through technology upgrading, cost efficiencies, commercial and supply optimization and continuing process streamlining across all businesses. Over the next four years, Eni plans to execute a capital expenditure program amounting to euro 53.3 billion to support continuing organic growth in its businesses, mainly Exploration & Production. In 2011, Eni intends to invest approximately euro 14 billion, an amount roughly in line with 2010. Eni plans to fund those capital expenditure projects mainly by means of cash flows provided by operating activities. Capital projects will be assessed and implemented in accordance with strict financial criteria. Management intends to progressively reduce the ratio of net borrowings to shareholders’ equity leveraging on projected cash flows from operations at our Brent scenario of $70 a barrel flat in the next four years and planned divestments amounting to euro 2 billion in 2011. This target includes expected cash outflows to remunerate Eni’s shareholders through a progressive dividend policy. In 2010 management plans to distribute a dividend of euro 1 a share subject to approval from the General Shareholders Meeting scheduled on May 5, 2011. In subsequent years, management plans to increase dividends in line with OECD inflation. This dividend policy is based on the Company’s planning assumptions for Brent prices and other assumptions (see "Item 5 – Outlook" and "Item 3 – Risk Factors").

Further details on each business segment strategy are discussed throughout this Item 4. For a description of risks and uncertainties associated with the Company’s outlook, including any possible impact associated with ongoing political instability and war in Libya, and the capital expenditure program see "Item 5 – Outlook" and "Item 3 – Risk Factors".

In the next four-year period, Eni plans to spend euro 1.1 billion for technological research and innovation activities. Management believes that technological leadership is a key driver of the Company’s competitive

advantages in the long-term. Eni concentrates most of its efforts in upstream projects focused on maximizing the recovery rate of hydrocarbons from reservoirs, optimizing drilling and well performance, exploiting unconventional oil and gas resources and improving exploration performance. Projects in the refining sector target the development of advanced fuels, that allow higher engine performance with minimum environmental impact, and the increase in valuable products yields from refining heavy and sour crude qualities (in particular the Eni Slurry Technology (EST) project). In the petrochemical sector, efforts are focused on developing high value added elastomers and polymers. We also intend to enhance our long-term options to contribute to sustainable development by progressing our capabilities in renewable sources of energy, particularly in the field of solar and photovoltaic energy, carbon capture and sequestration, clean fuels, operations safety and integrity in upstream, and environmental clean-up and remediation.

> Significant Business and Portfolio Developments

The significant business and portfolio developments that occurred in 2010 and to date in 2011 were the following:

• |  | From February 22, 2011, liquids and natural gas production at a number of fields in Libya and supplies through the GreenStream pipeline have been halted as a result of ongoing political instability and unrest in the Country. Facilities have not suffered any damage and such standstills do not affect Eni’s ability to ensure natural gas supplies to its customers. Eni is technically able to resume gas production at or near previous level once the situation stabilizes. The overall impact of the political instability and conflict in Libya on Eni’s results of operations and cash flows will depend on how long such tensions will last as well as on their outcome, which management is currently unable to predict. Eni’s oil and natural gas production as of end of March 2011, was flowing at a rate ranging from 70 to 75 KBBL/d, down from the expected level of approximately 280 KBBL/d. Production is continuing to decline. Current production mainly consists of gas that is entirely delivered to local power generation plant. For further discussion on risks and management outlook on the Libyan situation see "Item 3 – Risk Factors – Political Considerations" and "Item 5 – Outlook".
• |  | In November 2010, Eni and the Venezuelan State Company PDVSA established a joint venture in charge of developing the Junín 5 oil field, located in the Orinoco Oil Belt. Management believes that the field contains important volumes of resources, mainly heavy oil. The two partners plan to achieve first oil by 2013.
• |  | In 2010, appraisal activities were performed in the gas discovery of Perla located in the Cardón IV Block, in the shallow water of the Gulf of Venezuela. Based on the assessment made, management believes that Perla contains significant amount of gas reserves. The initiative is conducted through a 50/50 joint venture with another international oil. The two partners are planning for starting production in 2013.
• |  | At the beginning of the fourth quarter 2010, Eni achieved project milestones at the Zubair oil field in Iraq by increasing production by more than 10% above the initial production rate of approximately 180 KBBL/d. Increasing production above that level means that Eni has begun the cost recovery for its work on the field by booking its share of production, including receiving a remuneration fee for every extra barrel of oil produced above the 10% target. Eni, with a 32.8% share, is leading the consortium in charge of redeveloping the Zubair field over a 20-year period, targeting a production plateau of 1.2 mmBBL/d in the next six years.
• |  | In October 2010, with a view to rationalizing its upstream portfolio, Eni divested its subsidiary Società Padana Energia to Gas Plus. The divested subsidiary includes exploration leases and concessions for developing and producing oil and natural gas in Northern Italy. For further details, see "Exploration & Production – Italy", below.
• |  | In May 2010, Eni signed a preliminary agreement with an affiliate of Petrobras for the divestment of its 100% interest in Gas Brasiliano Distribuidora, a company that markets and distributes gas in an area of the S. Paulo State, Brazil. The completion of the transaction is subject to approval of the relevant Brazilian Authorities. The expected cash consideration amounts to $250 million.
• |  | In April 2010, Eni sold to NOC (Libyan National Oil Corp) a 25% stake in the share capital and the control of GreenStream BV, the company owning and managing the gas pipeline for importing to Italy natural gas produced in Libya.
• |  | Procedures for divesting Eni’s interests in the German TENP, the Swiss Transitgas and the Austrian TAG gas transport pipelines and carrier companies are progressing and the Company targets to finalize the divestiture in 2011. The divestment program has been agreed upon with the European Commission as remedial actions to settle an antitrust proceeding without the ascertainment of any illicit behavior and consequently without imposition of any fines or sanctions on the Company. The proceeding was started by the Commission in the year 2006 to investigate allegedly anti-competitive behavior ascribed to Eni in the natural gas market. The commitments have been ratified as of September 29, 2010.

In addition, in 2010 and up to date in 2011 Eni closed the following transactions:

BUSINESS OVERVIEW

Exploration & Production

Eni’s Exploration & Production segment engages in oil and natural gas exploration and field development and production, as well as LNG operations, in 43 countries, including Italy, Libya, Egypt, Norway, the UK, Angola, Congo, the USA, Kazakhstan, Russia, Algeria, Australia, Venezuela and Iraq. In 2010, Eni average daily production amounted to 1,757 KBOE/d on an available for-sale basis. As of December 31, 2010, Eni’s total proved reserves amounted to 6,843 mmBOE; proved reserves of subsidiaries stood at 6,332 mmBOE; Eni’s share of reserves of equity-accounted entities amounted to 511 mmBOE.

Eni’s strategy in its Exploration & Production operations is to pursue profitable production growth leveraging on the Company’s portfolio of assets and pipeline of development projects. We plan to achieve a compound average growth rate in our production in excess of 3% in the next 2011-2014 four-year period, targeting a production plateau above 2.05 mmBOE/d by 2014. Those targets are based on our long-term Brent price assumptions of 70 $/BBL. The production outlook for 2011 is uncertain due to ongoing political instability and unrest in Libya. Following suspension of activities at several of Eni’s producing sites in Libya and the closure of a pipeline transporting gas from Libya to Italy, Eni’s production in Libya as of end of March 2011, was flowing at a rate ranging from 70 to 75 KBOE/d compared to an expected level for 2011 of approximately 280 KBOE/d. Production is continuing to decline. Future developments in Libya, which we are currently unable to predict, may have a material adverse effect on Eni’s production targets. However, in our planning assumptions to 2014 we assumed that the Libyan production would resume flowing at its normal rate at some point in the future. For further information on this issue as well as certain other trading environment assumptions including an indication of Eni’s production volume sensitivity to oil prices see "Item 5 – Outlook" and "Item 3 – Risk Factors".

Management plans to achieve the target of production growth to 2014 via organic developments, leveraging on the planned start-ups of a number of fields and material expenditures to support current production levels at our producing fields. We project that new fields start-ups will add approximately 630 KBOE/d to the Company’s production level by 2014. Main production start-ups are planned in Angola, Norway, Russia, Kazakhstan, Algeria and Venezuela. We have a good level of visibility on those new projects as most of them have been already sanctioned.

The second leg of our growth strategy is to maximize the production recovery rate at our current fields by counteracting natural field depletion. To achieve this, we plan to execute infilling and work-over activities, apply our advanced recovery technologies and reservoir management capabilities.

In exploration activities, Eni plans to perform the major part of exploration projects in well-established areas of presence targeting to extend the plateau of producing fields. Those areas include Egypt, Pakistan, Nigeria, Congo and the Gulf of Mexico where availability of production facilities will enable the Company to readily put in production discovered reserves. Other projects will be executed offshore of West Africa, Venezuela and in deepwater plays in the Gulf of Mexico where the Company believes to have the necessary know-how and skills to discover new reserves. A third layer of exploration projects is planned to be executed in high risk/high reward areas including Mozambique, Togo, Ghana and offshore Australia and East Timor where the Company believes important resources can be discovered. Eni expects to purchase new exploration permits and to divest or exit marginal or non-strategic areas.

Eni intends to focus on reserve replacement in order to ensure the medium to long-term sustainability of the business. Management intends to implement a number of initiatives to support profitability in its upstream operations by exercising tight cost control and reducing the time span which is necessary to put reserves in production. We expect that costs to develop and operate fields will increase in the next years due to sector-specific inflation, and growing complexity of new projects. We plan to counteract those cost increases by leveraging on cost efficiencies associated with: (i) increasing the scale of our operations as we concentrate our resources on fields of greater dimensions than in the past where we plan to achieve economies of scale; (ii) expanding the scope of operated production. We believe that is a key driver of profitability as operatorship will enable the Company to exercise better cost control, effectively manage reservoir and production operations, and deploy our safety standards and procedures to minimize risks; and (iii) applying our technologies which we believe can reduce drilling and completion costs.

Eni intends to optimize its portfolio of development properties by focusing on areas where its presence is established, and divesting non-strategic or marginal assets. Eni also intends to develop certain LNG project in order to monetize its large base of gas reserves mainly in West Africa.

Management plans to invest approximately euro 39.1 billion to explore for and develop new reserves over the next four years. Exploration projects will account for approximately euro 3.6 billion. Approximately euro 1.8 billion will be spent to build transportation infrastructures and LNG projects through equity-accounted entities. For the year 2011, management plans to spend euro 9.8 billion in reserves development and exploration projects.

> Disclosure of Reserves

> Overview

The Company has adopted comprehensive classification criteria for the estimate of 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 those quantities of liquids (including condensates and natural gas liquids) and natural gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain.

Oil and natural gas prices used in the estimate of proved reserves are obtained from the official survey published by Platt’s Marketwire, except when their calculation derives from existing contractual conditions. Prices are calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period. Prices include consideration of changes in existing prices provided only by contractual arrangements.

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 evaluation. 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. 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. Proved reserves to which Eni is entitled under Production Sharing Agreements 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 (profit oil). A similar scheme applies to buy-back and service contracts.

> Reserves Governance

Eni exercises rigorous control over the process of booking proved reserves, through a centralized model of reserve governance. The Reserves Department of the Exploration & Production Division is entrusted with the task of: (i) ensuring the periodic certification process of proved reserves; (ii) continuously updating the Company’s guidelines on reserves evaluation and classification and the internal procedures; and (iii) providing training of staff involved in the process of reserves estimation.

27

##### Table of Contents

Company guidelines have been reviewed by DeGolyer and MacNaughton (D&M), an independent petroleum engineering company, which has stated that those guidelines comply with the SEC rules1. D&M has also stated that the Company guidelines provide reasonable interpretation of facts and circumstances in line with generally accepted practices in the industry whenever SEC rules may be less precise. When participating in exploration and production activities operated by others entities, Eni estimates its share of proved reserves on the basis of the above guidelines.

The process for estimating reserves, as described in the internal procedure, involves the following roles and responsibilities: (i) the business unit managers (geographic units) and Local Reserves Evaluators (LRE) are in charge with estimating and classifying gross reserves including assessing production profiles, capital expenditures, operating expenses and costs related to asset retirement obligations; (ii) the Petroleum Engineering Department at the head office verifies the production profiles of such properties where significant changes have occurred; (iii) geographic area managers at the head office verify estimates carried out by business unit managers; (iv) the Planning and Control Department provides the economic evaluation of reserves; (v) the Reserve Department, through the Division Reserves Evaluators (DRE), provides independent reviews of fairness and correctness of classifications carried out by the abovementioned units and aggregates worldwide reserve data.

The head of the Reserve Department attended the "Politecnico di Torino" and received a Master of Science degree in Mining Engineering in 1985. She has more than 20 years of experience in the oil and gas industry and more than 10 years of experience specifically in evaluating reserves.

Staff involved in the reserves evaluation process fulfills the professional qualifications requested and maintains the highest level of independence, objectivity and confidentiality in accordance with professional ethics. Reserves Evaluators qualifications comply with international standards established by the Society of Petroleum Engineers.

> Reserves independent evaluation

Since 1991, Eni has requested independent oil engineering companies to carry out an independent evaluation2 of part of its proved reserves on a rotational basis. Management believes that those engineering firms are qualified and experienced on the marketplace. The description of qualifications of the persons primarily responsible for the reserve audit is included in the third party audit report3. In the preparation of their reports, independent evaluators rely, without independent verification, upon information furnished by Eni with respect to property interests, production, current costs of operations and development, sale agreements, prices and other factual information and data that were accepted as represented by the independent evaluators. This data, equally used by Eni in its internal process, include logs, directional surveys, core and PVT (Pressure Volume Temperature) analysis, maps, oil/gas/water production/injection data of wells, reservoir studies; technical analysis relevant to field performance, reservoir performance, long-term development plans, future capital and operating costs.

In order to calculate the economic value of Eni’s equity reserves, actual prices applicable to hydrocarbon sales, price adjustments required by applicable contractual arrangements and other pertinent information are provided. In 2010, Ryder Scott Company and DeGolyer and MacNaughton provided an independent evaluation of 28% of Eni’s total proved reserves at December 31, 20104, confirming, as in previous years, the reasonableness of Eni internal evaluation5.

In the 2008-2010 three-year period, 78% of Eni total proved reserves were subject to an independent evaluation. As at December 31, 2010 the principal Eni properties not subjected to independent evaluation in the last three years were Karachaganak (Kazakhstan), Samburgskoye and Yaro-Yakhinskoye (Russia).

> Summary of proved oil and gas reserves

The tables below provide a summary of proved oil and gas reserves of the Group companies and its equity-accounted entities by geographic area for the three years ended December 31, 2010, 2009 and 2008. Reserves data for 2010 and 2009 are based on the un-weighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period. Data for 2008 is based on the last day price of the Company’s fiscal year in accordance with then applicable rules.

Eni’s proved reserves of subsidiaries as of December 31, 2010 totaled 6,332 mmBOE (oil and condensates 3,415 mmBBL; natural gas 16,198 BCF) representing an increase of 123 mmBOE, or 2%, from December 31, 2009. Additions to proved reserves booked in 2010 were 776 mmBOE (including the impact of gas conversion factor update equal to 97 mmBOE) and derived from: (i) revisions of previous estimates were 661 mmBOE mainly reported in Libya, Nigeria, Egypt, Iraq and Italy; (ii) extensions, discoveries and other factors were 125 mmBOE, with major increase booked in the UK and Algeria; and (iii) improved recovery were 2 mmBOE. The unfavorable effect of higher oil price on reserve entitlements in certain PSAs and service contracts (down 80 mmBOE) resulted from higher oil prices compared to year ago (the Brent price used in the reserve estimation process was $79 per barrel in 2010 compared to $59.9 per barrel in 2009). Higher oil prices also resulted in upward revisions associated with improved economics of marginal productions.

In 2010, sales of mineral-in-place resulted mainly from the divestment of wholly-owned subsidiary Società Padana Energia to Gas Plus, which held exploration, development and production properties in Northern Italy.

As of December 31, 2010 Eni’s share of proved reserves of equity-accounted entities amounted to 511 mmBOE, an increase of 149 mmBOE, or 41.2%, compared to December 31, 2009, with an increase mainly reported in Venezuela.

The current SEC rules allow the use of reliable technology to justify the reserves estimate if it produces consistent and repeatable results. We did not have any material additions of proved reserves due to application of "reliable technologies".

Proved developed reserves of subsidiaries as of December 31, 2010 amounted to 3,926 mmBOE (1,951 mmBBL of liquids and 10,965 BCF of natural gas) representing 62% of total estimated proved reserves (65% and 63% as of December 31, 2009 and 2008, respectively).

The reserve replacement ratio for Eni’s subsidiaries and equity-accounted entities was 125% in 2010 (96% in 2009 and 135% in 2008). The ratio did not include the impact associated with adoption of a new conversion factor of natural gas to barrel-of-oil equivalent on the initial balances of proved reserves as of January 1, 2010 as management believes that that change did not pertain to the Company’s reserve performance for the year. The reserve replacement ratio was calculated by dividing additions to proved reserves by total production, each as derived from the tables of changes in proved reserves prepared in accordance with FASB Extractive Activities - Oil & Gas (Topic 932) (see the supplemental oil and gas information in the Consolidated Financial Statements). The reserve replacement ratio is a measure used by management to assess the extent to which produced reserves in the year are replaced by reserve additions booked. Management considers the reserve replacement ratio to be an important indicator of the Company ability to sustain its growth perspective. However, this ratio measures past performances and is not an indicator of future production because the ultimate recovery of reserves is subject to a number of risks and uncertainties. These include the risks associated with the successful completion of large-scale projects, including addressing ongoing regulatory issues and completion of infrastructures, as well as changes in oil and gas prices, political risks and geological and other environmental risks. Specifically, in recent years Eni’s reserves replacement ratio has been affected by the impact of higher oil prices on reserves entitlements in the Company’s Production Sharing Agreements (PSAs) and similar contractual schemes. In accordance with such contracts, Eni is entitled to a portion of field reserves, the sale of which should cover expenditures incurred by the Company to develop and operate the field. The higher the reference prices for Brent crude oil used to determine year

end amounts of Eni’s proved reserves, the lower the number of barrels necessary to cover the same amount of expenditures. In 2010, this trend resulted in a lower amount of booked reserves associated with the Company’s PSAs as the average oil price used in reserve computation was higher than the previous year. See "Item 3 – Risks associated with exploration and production of oil and natural gas – and – Uncertainties in Estimates of Oil and Natural Gas Reserves".

The average reserve life index of Eni’s proved reserves was 10.3 years as of December 31, 2010 which included reserves of both subsidiaries and equity-accounted entities.

> Proved undeveloped reserves

Proved undeveloped reserves as of December 31, 2010 totaled 2,821 mmBOE. At year end, liquids proved undeveloped reserves amounted to 1,620 mmBBL, mainly concentrated in Africa and Kazakhstan. Natural gas proved undeveloped reserves accounted for 6,671 BCF, mainly located in Africa and Russia.

In 2010, total proved undeveloped reserves increased by 354 mmBOE. The principal reasons for the increase are revisions and new projects sanction, mainly in Libya, Venezuela and Iraq.

During 2010, Eni converted approximately 295 mmBOE of proved undeveloped reserves to proved developed reserves. The main reclassification to proved developed were related to development activities, revisions and production start-up of the following fields/projects: Cerro Falcone (Italy), M’Boundi (Congo), Wafa (Libya), Bhit and Sawan (Pakistan), Morvin (Norway), Tuna and Hapy (Egypt) and Karachaganak (Kazakhstan).

In 2010, capital expenditures amounted to approximately euro 1.7 billion and were made to progress the development of proved undeveloped reserves.

Reserves that remain proved undeveloped for five or more years are a result of several physical factors that affect the timing of the projects development and execution, such as the complex nature of the development project in adverse and remote locations, physical limitations of infrastructure or plant capacities and contractual limitations that establish production levels.

The Company estimates that approximately 0.9 BBOE of proved undeveloped reserves have remained undeveloped for five years or more with respect to the balance sheet date, mainly related to: (i) the Kashagan project in Kazakhstan (0.6 BBOE) where development activities are progressing and start-up production is targeted by the end of 2012. For more details regarding this project please refer to part 1, Item 4, page 46, where the project is disclosed. See also our discussion under the "Risk Factors" section about risks associated with oil and gas development projects on page 6; (ii) certain Libyan gas fields where development activities and production start-up is dependent upon fulfilling contractual delivery obligations under a long-term gas supply agreement; and (iii) other minor projects where development activities are progressing.

> Delivery commitments

Eni sells crude oil and natural gas from its producing operations under a variety of contractual obligations. Some of these contracts, mostly relating to natural gas, specify the delivery of fixed and determinable quantities.

Eni is contractually committed under existing contracts or agreements to deliver over the next three years natural gas to third parties for a total of approximately 1,852 BCF from producing properties located in Australia, Egypt, India, Indonesia, Libya, Nigeria, Norway, Pakistan, Tunisia and the UK.

The temporary shut down of the GreenStream pipeline due to ongoing political instability and unrest in Libya will not materially impair the Company’s ability to fulfill its contractual delivery commitments with third parties as the Company can make use of its gas availability from various sources to meet those commitments.

The sales contracts contain a mix of fixed and variable pricing formulas that are generally referenced to the market price for crude oil, natural gas or other petroleum products.

Management believes it can satisfy these contracts from quantities available from production of the Company’s proved developed reserves and supplies from third parties based on existing contracts. Production will account for approximately 68% of outstanding delivery commitments in the next three years.

Eni has met all contractual delivery commitments as of December 31, 2010.

> Oil and gas production, production prices and production costs

The matters regarding future production, additions to reserves and related production costs and estimated reserves discussed below and elsewhere herein are forward-looking statements that involve risks and uncertainties that could cause the actual results to differ materially from those in such forward-looking statements. Such risks and uncertainties relating to future production and additions to reserves include political developments affecting the award of exploration or production interests or world supply and prices for oil and natural gas, or changes in the underlying economics of certain of Eni’s important hydrocarbons projects. Such risks and uncertainties relating to future production costs include delays or unexpected costs incurred in Eni’s production operations.

In 2010, oil and natural gas production available for sale averaged 1,757 KBOE/d. Production for the year expressed in barrel-of-oil equivalent was calculated assuming a natural gas conversion factor which was updated to 5,550 CF of gas equaling 1 barrel of oil. On a comparable basis, i.e. when excluding the effect of the update gas conversion factor, production showed an increase of 0.9% for the full year. Production growth was driven by additions from new field start-ups, particularly the Zubair field (Eni’s interest 32.8%) in Iraq, and production ramp-ups at fields which were started-up in 2009 (for a total increase of 40 KBOE/d). These increases were offset in part by mature field declines. Lower entitlements in the Company’s PSA due to higher oil prices, as well as lower gas uplifts in Libya as a result of oversupply conditions in the European market were partly offset by lower OPEC restrictions resulting in a net negative impact of approximately 7 KBOE/d. The share of oil and natural gas produced outside Italy was 90% (90% in 2009).

Liquids production (997 KBBL/d) decreased by 10 KBBL/d from 2009 (down 1%). The impact of mature field declines was partly offset by organic growth and production start-ups achieved in particular in Nigeria, due to the ramp-up of the Oyo project (Eni’s interest 40%), in Italy as a result of the ramp-up of the Val d’Agri enhanced development project (Eni’s interest 60.77%), in Tunisia due to the production start-up/ramp-up of the Baraka and Maamoura projects (Eni operator with a 49% interest) as well as Zubair in Iraq.

Natural gas production (4,222 mmCF/d) increased by 148 mmCF/d from 2009 (up 3.6%). The main increases were registered in Nigeria, due to projects start-up in the Block OML 28 (Eni’s interest 5%), in Australia, due to ramp-up of the Blacktip project (Eni’s interest 100%), in Congo, due to ramp-up of the M’Boundi gas project (Eni operator with an 83% interest) in Egypt, due to start-up of the Tuna field (Eni operator with a 50% interest), in Italy, due to the start-up of the Annamaria field (Eni operator with an 90% interest) and in India, due to organic growth of PY-1 project (Eni’s interest 47.18%). These increases were offset in part by mature field declines.

Oil and gas production sold amounted to 638 mmBOE. The 24.5 mmBOE difference over production (662.5 mmBOE for the year ended December 31, 2010) reflected volumes of natural gas consumed in operations (20.9 mmBOE).

Approximately 58% of liquids production sold (361.3 mmBBL) was destined to Eni’s Refining & Marketing Division (of which 18% was processed in Eni’s refinery); about 28% of natural gas production sold (1,536 BCF) was destined to Eni’s Gas & Power Division.

> Oil and gas properties, operations and acreage

As of December 31, 2010, Eni’s mineral right portfolio consisted of 1,176 exclusive or shared rights for exploration and development in 43 countries on five continents for a total acreage of 320,961 square kilometers net to Eni of which developed acreage was 41,386 square kilometers and undeveloped acreage was 279,575 square kilometers.

In 2010, changes in total net acreage mainly derived from: (i) new leases in Poland, Democratic Republic of Congo, Togo, Angola, Pakistan and Venezuela for a total acreage of approximately 13,000 square kilometers; (ii) the divestment of wholly-owned subsidiary Società Padana Energia and leases in Nigeria for a total acreage of

approximately 1,500 square kilometers; (iii) the total relinquishment of mainly exploration leases in Pakistan, Australia, Congo, Italy, Egypt, Russia and East Timor, covering an undeveloped acreage in excess of 23,000 square kilometers; and (iv) the decrease in net acreage due to partial relinquishment or interest reduction in Mali and Indonesia for a total net acreage of approximately 15,000 square kilometers.

The table below provides certain information about the Company’s oil and gas properties. It provides the total gross and net developed and undeveloped oil and natural gas acreage in which the Group and its equity-accounted entities had interest as of December 31, 2010.

Eni’s principal oil and gas properties are described below. In the discussion that follows, references to hydrocarbon production are intended to represent hydrocarbon production available for sale.

Italy Eni has been operating in Italy since 1926. In 2010, Eni’s oil and gas production amounted to 178 KBOE/d. Eni’s activities in Italy are deployed in the Adriatic Sea, the Central Southern Apennines, mainland and offshore Sicily and the Po Valley. Eni’s exploration and development activities in Italy are regulated by concession contracts. In October 2010, with a view to rationalizing its upstream portfolio, Eni closed the divestment of the entire share capital of its subsidiary Società Padana Energia to Gas Plus. The divested subsidiary includes exploration leases and concessions for developing and producing oil and natural gas in Northern Italy. Cash consideration for the deal amounted to euro 179 million, subject to a possible adjustment of up to euro 25 million related to achieving certain production targets at assets under development. Further price adjustments are foreseen in connection with appraising the underlying exploration resources. The Law Decree No. 128 issued by the Italian Government on June 29, 2010 that introduced certain restrictions for exploration and production hydrocarbons activities mainly in certain offshore and coastline areas due to environmental constrains without impacting the leases already granted to conduct oil and gas operations became effective on August 26, 2010. Eni and other operators in the industry have commenced discussions with the Ministry for Economic Development and the Ministry for the Environment to clarify uncertainties in correctly interpreting and applying the new regulations. During the year the Group did not incur any significant impact on its operations related to this new decree, while certain projects initially planned for 2011 have been rescheduled. For further information on this matter, see "Environmental matters" below. |  |

The Adriatic Sea represents Eni’s main production area in Italy, accounting for 55% of Eni’s domestic production in 2010. Main operated fields are Barbara, Angela-Angelina, Porto Garibaldi, Cervia and Bonaccia (for an overall production of approximately 212 mmCF/d).

Eni is the operator of the Val d’Agri concession (Eni’s interest 60.77%) in the Basilicata Region in Southern Italy. Production from the Monte Alpi, Monte Enoc and Cerro Falcone fields is fed by 24 production wells and is treated by the Viggiano oil center with an oil capacity of 104 KBBL/d. Oil produced is carried to Eni’s refinery in Taranto via a 136-kilometer long pipeline. Gas produced is treated at the Viggiano oil center and then delivered to the national grid system. In 2010, the Val d’Agri concession produced 88 KBOE/d (47 net to Eni) representing 26% of Eni’s production in Italy.

Eni is the operator of 15 production concessions onshore and offshore in Sicily. Its main fields are Gela, Ragusa, Giaurone, Fiumetto and Prezioso, which in 2010 accounted for 10% of Eni’s production in Italy.

|  | In 2010, production was started-up at: (i) the Annamaria B production platform (Eni operator with a 90% interest), located at the border with Croatian territorial waters. During the course of the year the field reached its production plateau at approximately 40 mmCF/d; and (ii) the Bonaccia Est field flowing at the initial rate of approximately 36 mmCF/d. In 2010, development activities progressed at the Val d’Agri concession (Eni’s interest 60.77%) as wells at Cerro Falcone were connected to the oil treatment centre. Other activities were performed including: (i) optimization of producing fields by means of sidetrack and work over activities (Barbara, Annalisa and Azalea); (ii) sidetrack programs and facility upgrading in Val d’Agri; (iii) upgrading activities of compression plants and treatment facilities at the Crotone plants; and (iv) development activities at the Capparuccia, Tresauro and Guendalina fields. In the medium-term, management expects production in Italy to slightly increase due to the production ramp-up of the Val d’Agri fields and ongoing new field projects and continuing production optimization activities partly offset by mature fields decline and divested fields.

Rest of Europe Eni’s operations in the Rest of Europe are conducted mainly in Croatia, Norway and the UK. In 2010, the Rest of Europe accounted for 12% of Eni’s total worldwide production of oil and natural gas. Croatia. Eni has been present in Croatia since 1996. In 2010, Eni’s production of natural gas averaged 42 mmCF/d. Activities are deployed in the Adriatic Sea near the city of Pula. Exploration and production activities in Croatia are regulated by PSAs. The main producing gas fields are Annamaria B (start-up in 2010, as disclosed above), Ivana, Ika & Ida, Marica and Katarina are operated by Eni through a 50/50 joint operating company with the Croatian oil company INA. Norway. Eni has been operating in Norway since 1964. Eni’s activities are performed in the Norwegian |  |

Sea, in the Norwegian section of the North Sea and in the Barents Sea. Eni’s production in Norway amounted to 120 KBOE/d in 2010.

Exploration and production activities in Norway are regulated by Production Licenses (PL). According to a PL, the holder is entitled to perform seismic surveys and drilling and production activities for any given number of years with possible extensions.

|  | Eni currently holds interests in 6 production areas in the Norwegian Sea. The principal producing fields are Aasgard (Eni’s interest 14.82%), Kristin (Eni’s interest 8.25%), Heidrun (Eni’s interest 5.12%), Mikkel (Eni’s interest 14.9%), Yttergryta (Eni’s interest 9.8%), Norne (Eni’s interest 6.9%) and Urd (Eni’s interest 11.5%) which in 2010 accounted for 72% of Eni’s production in Norway. In 2010, production was started-up at the Morvin field (Eni’s interest 30%) as three wells of the development program were put into production. Production is expected to peak at 15 KBOE/d net to Eni in 2011 when the project is completed. Development activities progressed to put in production discovered reserves near the Aasgard field with the Marulk development plan (Eni operator with a 20% interest). Start-up is expected in 2012. Eni holds interests in four production licenses in the Norwegian section of the North Sea. The main producing field is Ekofisk (Eni’s interest 12.39%) in PL 018, which in 2010 produced approximately 34 KBOE/d net to Eni and accounted for 28% of Eni’s production in Norway. The license expires in 2028, and negotiations are ongoing to grant an extension. Activities were performed during the year to maintain and optimize the production rate by means of infilling wells, the development of the South Area extension, upgrading of existing facilities and optimization of water injection.

Eni is currently performing exploration and development activities in the Barents Sea. Operations have been focused on developing the Goliat discovery made in 2000 at a water depth of 370 meters in PL 229 (Eni operator with a 65% interest). The license expires in 2042. The project is progressing according to schedule. In 2010, EPC contracts have been awarded for building an FPSO unit that will be linked to an underwater production system, onshore facilities and an offshore supply system designed to reduce CO2 emissions. Start-up is expected in 2013 while the production peak of 100 KBBL/d will be reached the following year.

Exploration activities yielded positive results in: (i) the Prospecting License 128 (Eni’s interest 11.5%) with the Fossekal oil discovery that will exploit synergies with the Norne (Eni’s interest 6.9%) production facilities; (ii) in the PL 473 license (Eni’s interest 29.4%) with the Flyndretind oil discovery; and (iii) the PL 532 (Eni’s interest 30%) with the Skrugard oil and gas discovery.

Poland. In December 2010, Eni acquired Minsk Energy Resources, which operates 3 licenses in the Polish Baltic Basin. Management believes that is a highly prospective shale gas play. Drilling operations are expected to start in the second half of 2011 with a total exploration commitment of 6 wells.

United Kingdom. Eni has been present in the UK since 1964. Eni’s activities are carried out in the British section of the North Sea, the Irish Sea and certain areas East and West of the Shetland Islands. In 2010, Eni’s net production of oil and gas averaged 87 KBOE/d.

Exploration and production activities in Algeria are regulated by Production Sharing Agreements (PSAs) and concession contracts. Production in Block 403a/d comes mainly from the HBN and Rom and satellite fields and represented approximately 23% of Eni’s production in Algeria in 2010. The main project underway is the integrated development of Rom and satellites reserves (Zea, Zek and Rec) following the mineral potential revaluation. The development plan has been approved by the relevant authorities. Current production is collected at the Rom Central Production Facility (CPF) and delivered to the treatment plant in Bir Rebaa North. An export pipeline has been completed and a new multiphase pumping system is under finalization in compliance with applicable country law to reduce gas flaring. Production in Blocks 401a/402a comes mainly from the Rod and satellite fields and accounted for approximately 23% of Eni’s production in Algeria in 2010. Infilling activities are being performed in order to maintain the current production plateau. The main fields in Block 403 are BRN, BRW and BRSW which accounted for approximately 17% of Eni’s production in Algeria in 2010. In Block 405b, the development activity relates to the MLE and CAFC integrated project. The final investment decision was sanctioned for both projects (MLE in 2009; CAFC in April 2010). The MLE development plan provides for the construction of a natural gas treatment plant with a capacity of 350 mmCF/d and of four export pipelines with linkage to the national grid system. These facilities will also receive gas from the CAFC field. |  |

As of December 31, 2010, 61% of MLE project was completed. The CAFC project provides the construction of an oil treatment plant and will also benefit from synergies with existing MLE production facilities. As of December 31, 2010, 27% of CAFC project was completed. MLE and CAFC start-up are expected in 2011 and 2012, respectively, with a production plateau of approximately 33 KBOE/d net to Eni by 2014.

Block 208 is located South of Bir Rebaa. The El Merk project is progressing with the drilling activities and the construction of treatment facilities. 60% of the project scope was completed at year end. Production start-up is expected in 2012.

The new Algerian hydrocarbon Law No. 5 of 2007 introduced a higher tax burden for the national oil company Sonatrach which has requested to renegotiate the economic terms of certain PSAs in order to restore the initial economic equilibrium. Eni signed an agreement for Block 403 in this respect while agreements have not yet been reached for Blocks 401a/402a (Eni’s interest 55%) and Block 208 (Eni’s interest 12.25%).

In the medium-term, management expects to increase Eni’s production in Algeria to approximately 120 KBOE/d, reflecting the development and integration of the First Calgary acquired assets.

Egypt. Eni has been present in Egypt since 1954. In 2010, Eni’s share of production in this country amounting to 222 KBOE/d and accounted for 13% of Eni’s total annual hydrocarbon production. Eni’s main producing liquid fields are located in the Gulf of Suez, primarily in Belayim field (Eni’s interest 100%) and in the Western Desert mainly Melehia concession (56% interest) and Ras Qattara (75% interest). Gas production mainly comes from the operated or participated concession of North Port Said (Eni’s interest 100%), El Temsah (50% interest), Baltim (50% interest) and Ras el Barr (50% interest, non-operated) and all located in the offshore the Nile Delta. In 2010, production from these main concessions accounted for approximately 90% of Eni’s production in Egypt.

Exploration and production activities in Egypt are regulated by Production Sharing Agreements.

|  | In July 2010, Eni signed a Strategic Framework Agreement with the Egyptian Ministry of Petroleum for new upstream and downstream initiatives. The agreement provides for: (i) a joint study to evaluate a number of upstream activities in the Mediterranean Basin and outside Egypt, including Gabon and Iraq; and (ii) an initiative to secure rights for Eni to acquire gas transport capacity in the Arab Gas Pipeline system in compliance with existing intergovernmental agreements. In May 2010, Eni divested a 50% interest in the Ashrafi offshore field located in the Gulf of Suez. Eni will retain operatorship and a 50% interest. Production start-up was achieved from Tuna field (Eni operator with a 50% interest) through linkage to the El Gamil facility with a production plateau at approximately 70 mmCF/d net to Eni. Other development activities mainly regarded: (i) the basic engineering of the Belayim field for the upgrading of water injection facilities to recover remaining reserves; (ii) the second phase of the Denise field (Eni operator with a 50% interest); and (iii) the upgrading of the El Gamil plant by adding new compression capacity to support production. Through its affiliate Unión Fenosa Gas, Eni has an indirect interest in the Damietta natural gas liquefaction plant with a producing capacity of 5.1 mmtonnes/y of LNG corresponding to approximately 268 BCF/y of

feed gas. Eni is currently supplying 35 BCF/y for a 20-year period. Natural gas supplies derived from the Taurt and Denise fields with 17 KBOE/d net to Eni of feed gas.

Exploration activities yielded positive results in the: (i) Belayim concession (Eni’s interest 100%) with two discovery wells containing oil that were linked to existing facilities; (ii) El Qara North (Eni’s interest 75%) and Zaafaran East (Eni’s interest 75%) gas discoveries which were linked to the existing nearby facilities; (iii) Melehia development lease (Eni’s interest 56%) with the Jana and Arcadia oil discoveries. The latter was started-up in the second half of the year.

In the medium-term, management expects that Egypt will remain among Eni’s largest oil and gas producing countries.

Libya. Eni started operations in Libya in 1959. In 2010, Eni’s oil and gas production averaged 267 KBOE/d, the portion of liquids being 43%. Production activity is carried out in the Mediterranean Sea near Tripoli and in the Libyan Desert area and includes six contract areas. Onshore contract areas are: (i) Area A consisting in the former concession 82 (Eni’s interest 50%); (ii) Area B, former concessions 100 (Bu Attifel field) and the NC 125 Block (Eni’s interest 50%); (iii) Area E with El Feel (Elephant) field (Eni’s interest 33.3%); and (iv) Area F with Block 118 (Eni’s interest 50%). Offshore contract areas are: (i) Area C with the Bouri oil field (Eni’s interest 50%); and (ii) Area D with Blocks NC 41 and NC 169 (onshore) that feed the Western Libyan Gas Project (Eni’s interest 50%). In the exploration phase, Eni is operator of four onshore blocks in the Muzurk Basin (161/1, 161/2&4, 176/3), in the Kufra area (186/1, 2, 3 & 4) and in the contract Areas A, B and D. Exploration and production activities in Libya are regulated by six Exploration and Production Sharing contracts (EPSA). The licenses of Eni’s assets in Libya expire in 2042 and 2047 for oil and gas properties, respectively. From February 22, 2011, some liquids and natural gas production activities and the gas export through the GreenStream pipeline have been halted. Facilities have not suffered any damage and such standstill does not affect Eni’s ability to ensure natural gas supplies to its customers. Eni is technically able to resume gas production at or near previous level once the situation stabilizes. The overall impact of instability and conflict in Libya on Eni’s results in terms of operations and cash flows will depend on how long such political instability and unrest will last, which management is currently unable to predict. Eni’s production as of end of March 2011, was flowing at around 70-75 KBOE/d, down from the expected level of approximately 280 KBOE/d, and is made of gas which is totally delivered to local power generation plants. Production is continuing to decline.. |  |

Eni has limited investments planned in Libya over the course of the next two years, and no major project start-up are planned for the next four years.

Main development activities underway concerned the Western Libyan Gas Project (Eni’s interest 50%) for the monetization of gas reserves ratified in the strategic agreements between Eni and NOC. Activities were performed for maintaining in the future gas production profiles at the Wafa and Bahr Essalam fields through increasing compression capacity at the Wafa field and drilling additional wells at both fields. In 2010, volumes delivered through the GreenStream pipeline were 309 BCF. In addition, 53 BCF were sold on the Libyan market for power generation and approximately 7 BCF to feed the GreenStream compressor station.

Tunisia. Eni has been present in Tunisia since 1961. In 2010, Eni’s production amounted to 19 KBOE/d. Eni’s activities are located mainly in the Southern Desert areas and in the Mediterranean offshore facing Hammamet.

##### Table of Contents

LNG, corresponding to a feedstock of approximately 1,624 BCF/y. Natural gas supplies to the plant are provided under gas supply agreements with a 20-year term from the SPDC joint venture (Eni’s interest 5%) and the NAOC JV, the latter operating the Blocks OMLs 60, 61, 62 and 63. In 2010, total supplies were 1,870 mmCF/d (191 mmCF/d net to Eni corresponding to 34 KBOE/d). LNG production is sold under long-term contracts and exported to European and American markets by the Bonny Gas Transport fleet, wholly owned by Nigeria LNG Co.

Eni holds a 17% interest of the Brass LNG Ltd Company for the construction of a natural gas liquefaction plant to be built near the existing Brass terminal, 100 kilometers West of Bonny. This plant is expected to start operating in 2016 with a production capacity of 10 mmtonnes/y of LNG corresponding to 590 BCF/y (approximately 60 net to Eni) of feed gas on 2 trains for twenty years. Supplies to this plant will derive from the gathering of associated gas from nearby producing fields and from the development of gas reserves in the onshore OMLs 60 and 61. The venture signed preliminary long-term contracts to sell the whole LNG production capacity. Eni acquired 1.67 mmtonnes/y of LNG capacity (corresponding to approximately 81 BCF/y). LNG will be delivered to the USA market mainly at the re-gasification plant in Cameron, in Louisiana. Eni’s capacity amounts to approximately 201 BCF/y. Front end engineering activities progressed. EPC tender exercise is ongoing. The final investment decision is envisaged in 2011.

In the medium-term, management expects to increase Eni’s production in Nigeria to approximately 190 KBOE/d, reflecting the development of gas reserves.

Togo. In October 2010, Eni awarded operatorship of offshore Block 1 and Block 2 (Eni 100%) in the Dahomey Basin as part of its agreements with the Government of Togo to develop the country’s offshore mineral resources.

> Kazakhstan

Eni has been present in Kazakhstan since 1992. Eni is co-operator of the Karachaganak field and partner in the North Caspian Sea Production Sharing Agreement (NCSPSA). In 2010, Eni’s operations in Kazakhstan accounted for 6% of its total worldwide production of oil and natural gas.

Kashagan. Eni holds a 16.81% working interest in the NCSPSA. The NCSPSA defines terms and conditions for the exploration and development activities to be performed in an area encompassing approximately 4,600 square kilometers. The Kashagan field was discovered in the Northern section of the contractual area in the year 2000.

46

##### Table of Contents

Management believes this field contains a large amount of hydrocarbon resources which will eventually be developed in phases. The PSA on Kashagan will expire at the end of 2041.

The participating interest in the NCSPSA has been redefined, effective as of January 1, 2008, in line with an agreement signed in October 2008 with Kazakh Authorities which proportionally diluted the participating interest of the international companies in favor of the Kazakh national oil company, KazMunaiGas. The Kazakh partner will pay the other co-venturers an aggregate amount of $1.78 billion for the transaction. Eni partners of the international consortium are the Kazakh national oil company, KazMunaiGas, and the international oil companies Total, Shell and ExxonMobil, each with a participating interest currently of 16.81%, ConocoPhillips with 8.40%, and Inpex with 7.56%.

The exploration and development activities of the Kashagan field and the other discoveries made in the contractual area are executed through an operating model which entails an increased role of the Kazakh partner and defines the international parties’ responsibilities in the execution of the subsequent development phases of the project. The new North Caspian Operating Co (NCOC) BV participated by the seven partners of the consortium has taken over the operatorship of the project. Subsequently development, drilling and production activities have been delegated by NCOC BV to the main partners of the Consortium: Eni has retained the responsibility for the development of Phase 1 of the project (the so-called "Experimental Program") and the onshore part of Phase 2.

The consortium is currently focused on completing Phase 1 and starting commercial oil production. Phase 1 completion as at December 2010 was around 80%, of which the completion of tranches 1 and 2 allowing the first production was around 90%.

The partners of the venture are currently discussing an update of the expenditures and time schedule to complete the Phase 1 which were included in the development plan approved in 2008 by the relevant Kazakh Authorities. The consortium continues to target the achievement of first commercial oil production by end of 2012. However, the timely delivery of Phase 1 depends on a number of factors which are presently under review.

The Phase 1 of the project targets an initial production capacity of 150 KBBL/d. In the 12-15 months following the start-up, the treatment plant and the compression facilities for gas re-injection will be started-up enabling an increase of the production capacity to 370 KBBL/d by 2014. A further increase of production capacity to 450 KBBL/d is expected as additional compression capacity for gas re-injection becomes available with the start-up of Phase 2 offshore facilities. Early engineering studies of Phase 2 are underway aiming at optimizing the development scheme.

Management believes that significant capital expenditures will be required in case the partners of the venture would sanction Phase 2 and possibly other additional phases. Eni will fund those investments in proportion to its participating interest of 16.81%. However, taking into account that future development expenditures will be incurred over a long time horizon and subsequently to the production start-up, management does not expect a material impact on the Company’s liquidity or its ability to fund these capital expenditures. In addition to the expenditures for developing the field, further capital expenditures will be required to build the infrastructures needed for exporting the production from Phase 2 and subsequent phases to the international markets.

As of December 31, 2010, Eni’s proved reserves booked for the Kashagan field amounted to 569 mmBOE, recording a decrease of 19 mmBOE with respect 2009 mainly due to price effect.

As of December 31, 2009, Eni’s proved reserves booked for the Kashagan field amounted to 588 mmBOE, recording a decrease of 6 mmBOE with respect to 2008.

As of December 31, 2008, Eni’s proved reserves booked for the Kashagan field amounted to 594 mmBOE determined according to Eni’s participating interest of 16.81%, recording an increase of 74 mmBOE with respect to 2007 despite the divestment of a 1.71% stake in the Kashagan project following the finalization of the agreements implementing the new contractual and governance framework of the project.

As of December 31, 2010, the aggregate costs incurred by Eni for the Kashagan project capitalized in the Consolidated Financial Statements amounted to $5.8 billion (euro 4.4 billion at the EUR/USD exchange rate of December 31, 2010). This capitalized amount included: (i) $4.5 billion relating to expenditures incurred by Eni for the development of the oil field; and (ii) $1.3 billion relating primarily to accrue finance charges and expenditures

for the acquisition of interests in the North Caspian Sea PSA consortium from exiting partners upon exercise of pre-emption rights in previous years.

Karachaganak. Located in West onshore Kazakhstan, Karachaganak is a liquid and gas field. Operations are conducted by the Karachaganak Petroleum Operating consortium (KPO) and are regulated by a PSA lasting 40 years, until 2037. Eni and British Gas are co-operators of the venture both with a 32.5% interest. In 2010, production of the Karachaganak field averaged 228 KBBL/d of liquids (65 net to Eni) and 812 mmCF/d of natural gas (221 net to Eni). This field is developed by producing liquids from the deeper layers of the reservoir and re-injecting the associated gas in the higher layers. Approximately 70% of liquid production are stabilized at the Karachaganak Processing Complex (KPC) with a capacity of approximately 200 KBBL/d and exported to Western markets through the Caspian Pipeline Consortium (Eni’s interest 2%) and the Atyrau-Samara pipeline. The remaining volumes of non-stabilized liquid production and associated gas not re-injected in the reservoir are marketed at the Russian terminal in Orenburg. The execution of the fourth treatment unit has been progressing towards completion and will enable to increase export of oil volumes to Western markets of currently non-stabilized liquids delivered to the Orenburg terminal. Phase 3 of the Karachaganak project targets to increase the development of gas and condensates reserves. The engineering activities identified a phased approach as the preferred development strategy with stage 1 of the project providing for the installation of gas producing and re-injection facilities to increase liquid production and gas sales in accordance with the foreseeable future market conditions. Technical and marketing discussion on Phase 3 with the relevant Kazakh Authorities are underway. |  |

As of December 31, 2010, Eni’s proved reserves booked for the Karachaganak field amounted to 557 mmBOE, recording a decrease of 76 mmBOE with respect to 2009 due to price effect and production of the year.

As of December 31, 2009, Eni’s proved reserves booked for the Karachaganak field amounted to 633 mmBOE, recording a decrease of 107 mmBOE with respect to 2008 in connection to downward revisions due to the impact of higher oil prices and the production of the year.

As of December 31, 2008, Eni’s proved reserves booked for the Karachaganak field amounted to 740 mmBOE, recording an increase of 200 mmBOE with respect to 2007 as a result of the upward revisions of previous estimates that were mainly related to higher entitlements reported in PSA resulting from lower year end oil prices from a year ago.

> Rest of Asia

In 2010, Eni’s operations in the rest of Asia accounted for 7% of its total worldwide production of oil and natural gas.

being operated by another international oil company) entered into with the National Iranian Oil Co (NIOC) between 1999 and 2001, and no other exploration and development contracts have been entered into since then. All projects mentioned above have been completed or substantially completed; the last one, the Darquain project, is in the process of final commissioning and is being handed over to NIOC. Operatorship has already been transferred to a NIOC affiliate. When hand over of operations is completed, Eni’s involvements will essentially consist of being reimbursed for its past investments. In 2010, Eni’s production in Iran was 21 KBOE/d, approximately 1% of the Group’s worldwide production. Eni does not believe that its activities in Iran have a material impact on the Group’s results. See "Item 3 – Risk Factors – Political Consideration – Iran" for a full discussion of risks involved by our presence in Iran.

Iraq. In January 2010, Eni leading a consortium of partners including international companies and the national oil company Missan Oil signed a technical service contract to develop the Zubair oil field (Eni 32.8%) with the Iraqi South Oil Company, under a 20-year term with an option for further 5 years extension. The field was awarded to the Eni-led consortium following a successful first bid round and was offered under a competitive bid starting on June 30, 2009. The development of the project foresees to gradually increase production to a target plateau level of 1.2 mmBBL/d over the next six years. The contract provides the recovery of expenditures incurred from the incremental production of the field and the recognition of a remuneration fee once the production has been raised by 10% from its initial level of approximately 180 KBBL/d. Development provides for two phases: (i) Rehabilitation plan, approved in June 2010, aimed at improving the current production level and the knowledge of the reservoir; and (ii) Redevelopment plan allowing to reach the scheduled targets. In 2010 all the milestones planned for the initial phase of the project were achieved. In particular in September 2010, production was raised by more than 10% above the initial production rate allowing the consortium, based on the contact provision, to begin recovery of costs and recognition of remuneration fee. Therefore Eni starting from the last quarter of 2010 booked its equity production in relation to its share of cost recovery and remuneration. |  |

##### Table of Contents

Gas & Power

Eni’s Gas & Power segment engages in supply, trading and marketing of gas and electricity, managing gas infrastructures for transport, distribution, storage, re-gasification, and LNG supply and marketing. This segment also includes the activity of power generation that is ancillary to the marketing of electricity. In 2010, Eni’s worldwide sales of natural gas amounted to 97.06 BCM, including 5.65 BCM of gas sales made directly by the Eni’s Exploration & Production segment in Europe and the USA. Sales in Italy amounted to 34.29 BCM, while sales in European markets were 54.52 BCM that included 8.44 BCM of gas sold to certain importers to Italy.

Gas transport, distribution and storage, as well as re-gasification of LNG in Italy are regulated activities as tariffs for the services rendered to gas operators and return on capital employed are set by an independent administrative body. For further description on those regulated activities see below.

> Marketing of natural gas

The competitive landscape in the marketing of gas in the pan-European sector has changed dramatically from late 2008 to date. Gas demand across Europe was severely impacted by the economic downturn and has been struggling to recover to pre-crisis levels as the industrial activity is slowly progressing, particularly in Italy.

On the supply side, gas availability has considerably increased on the marketplace due to capacity upgrading at the major international pipelines which carry natural gas from producing countries to Europe, including the TAG line from Russia and the TTPC line from Algeria. Also large quantities of LNG have been directed towards Europe as a number of important upstream projects started operations worldwide, and the U.S. market has progressively reduced its LNG imports due to commercial exploitation of large gas reserves from non-conventional sources. Several LNG terminals and facilities which were recently finalized commenced to receive those surpluses of LNG in Europe. The build up of LNG supplies at the European hubs has driven down spot prices which have fallen below the level of gas prices based on oil-linked formulas. That trend has impaired the profitability of gas operators, including Eni, whose portfolio of supplies is mainly indexed to the cost of oil and certain refined products as provided in purchasing formulas of long-term take-or-pay contracts, while spot prices have increasingly become the benchmark in selling formulas, particularly outside Italy.

In 2010, our gas marketing operations reported significantly lower operating profit driven by lower sales in Italy due to mounting competitive pressures and compressed unit margins in sales outside Italy. Operating profit for the year in the gas marketing business decreased by 64% from a year ago and represented less than 5% of the Group’s consolidated operating profit for 2010. The short-term outlook for the European gas sector remains challenging. Weak underlying fundamentals and strong competitive pressures are expected to stay in place for some time. Risks still exist in the next couple of years that the Company may be unable to fulfill its minimum take obligations associated with its long-term gas purchase contracts providing take-or-pay clauses. For a description of those risks see "Item 3 – Risk Factors" and "Item 5 – Outlook". However, management expects that the European gas market will rebalance by the end of the 2011-2014 period due to a number of trends. In fact, it is expected that demand will continue to recover to pre-crisis level and be driven by economic expansion and increased consumption by the power generation sector. Production from European fields will continue to deplete, increasing the need for gas imports. Also, LNG oversupplies will be progressively absorbed due to increasing energy requirements in other parts of the world and limited new capacity additions in the Atlantic Basin. In such a scenario, Eni’s long-term supply contracts and access to transport and storage infrastructures will again become a competitive advantage.

Against this backdrop, management plans to improve results in its gas marketing operations which management expects to recover to 2009 profitability levels by 2014. We intend to renegotiate better economic terms and operating conditions in our long-term gas purchase contracts, so as to restore the competitiveness of the Company’s cost position in the current weak scenario for the gas sector. The renegotiation of revised contractual terms, including any price revisions and contractual flexibility, is established by such contractual clauses whereby parties are held to bring the contract back to the economic equilibrium in case of significant changes in the market environment, like the ones that have been occurring from the second half of 2008. In the course of 2010, Eni has finalized a number of important contractual renegotiations by obtaining improved economic conditions for supplies and wider contractual flexibility with a benefit to its commercial programs. A number of renegotiations have commenced or are due to commence in the near future involving all the Company’s main suppliers of gas based on long-term contracts. The Company targets to grow sales volumes at an average annual rate of 5% both in Europe and Italy over the plan period; particularly we plan:

(i) |  | to increase gas sales volumes in European markets leveraging on the increased competitiveness of the Company’s cost position and its multiple presence in a number of markets. We target to expand sales mainly in France, Germany and Austria leveraging on new customized commercial offers and to retain the leadership in the Benelux market;
(ii) |  | to regain market share in the Italian market and preserve marketing margins leveraging on the commercial strength and capabilities of the Company, as well as the increased competitiveness of the Company’s cost

|  | position. Measures will be implemented to select the customer portfolio and retain clients by proposing new pricing offers and schemes and improve the service quality;
(iii) |  | to reduce the cost-to-serve, marketing and general and business support expenses;
(iv) |  | to monitor and effectively manage working capital requirements; and
(v) |  | to boost margins by means of new risk management activities.

For a description of uncertainties and risks associated with this strategy including a discussion of the possible consequences of the Libyan political instability and conflict see "Item 3 – Risk Factors" and "Item 5 – Outlook".

In the next four-year period, management plans to invest euro 1.1 billion in marketing activities mainly directed to: (i) power plant upgrading, including building a new bio-mass power generation plant at Eni’s Porto Torres industrial site where a reconversion plan is underway; and (ii) increasing flexibility of generation facilities.

The matters regarding future natural gas demand and sales target discussed in this section and elsewhere herein are forward-looking statements that involve risks and uncertainties that could cause the actual results to differ materially from those in such forward-looking statements. Such risks and uncertainties relating to future natural gas demand include changes in underlying economic factors, changes in regulation, population growth or shrinkage, changes in the relative mix of demand for natural gas and its principal competing fuels, and unexpected developments in the markets for natural gas and its principal competing fuels.

> Demand outlook

In 2010, gas demand in Italy and Europe rebounded from the depressed levels registered in the previous year, growing by 6% and 4%, respectively. Consumption volumes however remained below the pre-crisis levels seen in 2007. Looking forward, management estimates that long-term gas demand growth will achieve an average rate of 1.7% and 1.1% in Italy and Europe, respectively, until 2020. Those projections imply a consumption level of approximately 590 BCM for the Europe as a whole by 2020; while in Italy a consumption level of approximately 97 BCM is projected at 2020.

Those estimates have been revised down from previous management projections to factor in the expected impacts associated with a number of ongoing trends:

• |  | uncertainties and volatility in the current macroeconomic cycle;
• |  | growing adoption of consumption patterns and life-style characterized by wider sensitivity to energy efficiency; and
• |  | EU policies intended to reduce GHG emissions and promoting renewable energy sources. Specifically, legislation was voted by the European Parliament in December 2008 to enact a package of interventions in the European energy sector, the so-called "Climate Change and Renewable Energy Package". The package includes a commitment to reduce greenhouse gas (GHG) emissions by 20% by 2020 compared to emission levels recorded in 1990 (the target being 30% if an international agreement is reached), as well as an improved energy efficiency within the EU member states of 20% by 2020 and a 20% renewable energy target by 2020.

Among positive drivers for demand growth, it is worth mentioning the growing adoption of natural gas to fuel thermoelectric production via combined cycles and the higher environmental compatibility of natural gas than other fossil fuels to produce energy.

> Supply of natural gas

In 2010, Eni’s consolidated subsidiaries supplied 82.49 BCM of natural gas, representing a decrease of 6.16 BCM, or 6.9% from 2009 reflecting lower sales for the year.

Gas volumes supplied outside Italy (75.20 BCM from consolidated companies), imported in Italy or sold outside Italy, represented approximately 92% of total supplies, a decrease of 6.59 BCM, or 8.1%, from 2009, mainly reflecting a decline in natural gas sales. In 2010, lower volumes were purchased from: (i) Russia (down 7.73 BCM), where Eni reduced its off-takes in particular of volumes directed to Italy; (ii) the Netherlands (down 1.57 BCM); and (iii) Norway (down 1.17 BCM) also due to the impact of an accident that occurred at the import pipeline Transitgas in August 2010.

In 2010, increases were recorded in gas purchases from Algeria (up 2.41 BCM) and from the UK (up 1.8 BCM), as well as in LNG availability.

##### Table of Contents

Supplies in Italy (7.29 BCM) increased by 0.43 BCM from 2009, or 6.3%, also due to higher domestic production.

In 2010, main gas volumes from equity production derived from: (i) Italian gas fields (6.7 BCM); (ii) the Wafa and Bahr Essalam fields in Libya linked to Italy through the GreenStream pipeline. In 2010, these two fields supplied 2.5 BCM net to Eni; (iii) certain Eni fields located in the British and Norwegian sections of the North Sea (2.6 BCM); and (iv) other European areas (Croatia with 0.4 BCM).

Considering also the direct sales of the Exploration & Production Division in Europe and in the Gulf of Mexico and LNG supplied from the Bonny liquefaction plant in Nigeria, supplied gas volumes from equity production were approximately 20 BCM representing 21% of total volumes available for sale.

In 2010, volumes input to storage deposits owned by Eni’s subsidiary Stoccaggi Gas Italia amounted to 0.20 BCM compared to withdrawals from storage deposit 1.25 BCM in 2009.

The table below sets forth Eni’s purchases of natural gas by source for the periods indicated.

In order to secure long-term access to gas availability, particularly with a view of supplying the Italian gas market, Eni has signed a number of long-term gas supply contracts with key producing countries that supply the European gas markets. These contracts have been ensuring approximately 80 BCM of gas availability from 2010 (including the Distrigas portfolio of supplies) with a residual life of approximately 19 years and a pricing mechanism indexed to the price of crude oil and its derivatives (gasoil, fuel oil, etc). The contracts provide take-or-pay clauses whereby the Company is required to collect minimum pre-determined volumes of gas in each year of the contractual term or, in case of failure, to pay the whole price, or a fraction of that price, applied to uncollected volumes up to the minimum contractual quantity. The take-or-pay clause entitles the Company to collect pre-paid volumes of gas in later years during the period of contract execution. Amounts of cash pre-payments and time schedules for collecting pre-paid gas vary from contract to contract. Generally speaking, cash pre-payments are calculated on the basis of the energy prices current in the year of non-fulfillment with the balance due in the year when the gas is actually collected. Amounts of pre-payments range from 10 to 100 percent of the full price. The right to collect pre-paid gas expires within a ten-year term in some contracts or remains in place until contract expiration in other arrangements. In addition, rights to collect pre-paid gas in future years can be exercised provided that the Company has fulfilled its minimum take obligation in a given year and within the limit of the maximum annual quantity that can be collected in each contractual year. In this case, Eni will pay the residual price calculating it as the percentage that complements 100%, based on the arithmetical average of monthly base prices current in the year of the off-take. Similar considerations apply to ship-or-pay contractual obligations.

Management believes that the current outlook for increasing competition pressures coupled with large gas availability on the marketplace, the possible evolution of sector-specific regulation, as well as the de-coupling between trends in gas prices indexed to oil versus gas benchmark prices at spot markets, represent risks factors to the Company’s ability to fulfill its minimum take obligations associated with its long-term supply contracts.

##### Table of Contents

Particularly, management expects that the Company will experience increasing exposure to the risk associated with growing adoption on the marketplace of selling formulas linked to spot prices which movements are independent of those of oil prices and refined products that drive supply costs in Eni’s take-or-pay contracts.

In the years 2009 and 2010, Eni incurred the take-or-pay clause as the Company collected lower volumes than its minimum take obligations in each of those years accumulating deferred costs for an amount of euro 1.44 billion as of December 31, 2010. The Company’s ability to recover those pre-paid volumes within contractual terms will depend in future years on a number of factors, including the possible evolution of the market environment and the competitiveness of Eni’s cost position. Ongoing political instability in Libya and the shut down of the GreenStream pipeline may possibly counteract those negative trends as the Company may be able to replace supplies from Libya with gas from its ample portfolio. The latter trend will evolve depending on how long such political instability and conflict will last and on their outcome which for the time being cannot be foreseen.

In case Eni fails to off-take the contractual minimum amounts, it will be exposed to a price risk, because the purchase price Eni will ultimately be required to pay is based on prices prevailing after the date on which the off-take obligation arose. In addition, Eni is subject to the risk of not being able to dispose of pre-paid volumes. The Company also expects to incur financing costs to pay cash advances corresponding to contractual minimum amounts. As a result, the Company’s selling margins, results of operations and cash flow may be negatively affected.

Based on management’s projections for sales volumes and unit margins for the four-year plan and subsequent years which incorporated expected trends in the European market fundamentals, and management’s assumptions to renegotiate better economic terms within the Company’s long-term gas purchase contracts, so as to restore the competitiveness of the Company’s cost position, the Company believes that in the long-term it will be in the position to recover volumes of gas which have been pre-paid in 2009 and 2010 due to the take-or-pay clause and also possible new volumes associated with the contractual clause due to the uncertainties and weak conditions in the gas market over the next two years. Even if financing associated with cash advances is factored in, the net present value associated with those long-term purchase contracts discounted at the weighted average cost of capital for the Gas & Power segment still remains a positive and consequently those contracts do not fall within the category of the onerous contract provided by IAS 37.

> Natural Gas Sales for the Year 2010

In 2010, worldwide natural gas sales were 97.06 BCM, down 6.66 BCM, or 6.4%, mainly due to unfavorable trends on the Italian market. Sales included Eni’s own consumption, Eni’s share of sales made by equity-accounted entities and upstream sales in Europe and in the Gulf of Mexico.

Natural gas sales in Italy were 34.29 BCM (including own consumption and sales by affiliates) a decline of 5.75 BCM from 2009, or 14.4%, driven by increased competitive pressures and oversupply conditions on the marketplace, resulting in an estimated loss of ten percentage points in the Group market share in Italy. Particularly, lower sales were recorded in the power generation business (down 5.64 BCM), as clients opted to directly purchase gas on the marketplace. Lower sales to industrial customers (down 1.17 BCM) and wholesalers (down 1.08 BCM) were caused by increased competitive pressure fuelled by oversupply and weak demand. Sales on the Italian exchange for gas and spot market increased by 2.28 BCM, while sales volumes to the residential sector (6.39 BCM, up 0.09 BCM) were nearly unchanged. In addition, sales to importers in Italy were down by 2.04 BCM, or 19.5%, due to oversupply on the Italian market.

The Italian market includes large businesses, power generation users, wholesalers, middle-sized enterprises and service and residential customers; they are further grouped as follows: (i) large industrial clients and power generation utilities, directly linked to the national and the regional natural gas transport networks; (ii) wholesalers, mainly local selling companies which resell natural gas to residential customers through low pressure distribution networks and distributors of natural gas for automotive use; and (iii) residential customers, that include households (also referred to as the retail market), the tertiary sector (mainly commercial outlets, hospitals, schools and local administrations) and middle-sized enterprises (also referred to as the middle market) located in large metropolitan areas and urban areas.

As of December 31, 2010, Eni’s customers in Italy totaled 6.88 million.

Despite strong competitive pressures, sales on target markets in Europe showed a positive trend, increasing by approximately 1 BCM, or 2.5%, to 46.08 BCM. The main drivers behind the increase were organic growth achieved in France (up 1.18 BCM), Northern Europe (including the UK, up 0.91 BCM), Germany/Austria (up 0.31 BCM) and the Iberian Peninsula (up 0.30 BCM). Declines were recorded in Turkey (down 0.84 BCM), Belgium (down 0.80 BCM) and Hungary (down 0.22 BCM).

Sales to markets outside Europe (2.60 BCM) increased by 0.54 BCM, or 26.2%, from 2009.

E&P sales in Europe and in the USA (5.65 BCM) declined by 0.52 BCM.

> Marketing of Electricity

As part of its marketing activities in Italy, Eni engages in selling electricity on the Italian market principally on the open market, at industrial sites and on the Italian Exchange for electricity. Supplies of electricity include both own production volumes through gas-fired, combined-cycles facilities and purchases on the open market. This activity has been developed in order to capture further value along the gas value-chain leveraging on the Company’s large gas availability. In addition, with the aim of developing and retaining valuable customers in the residential space and middle to large industrial users, the Company has been developing a commercial offer that provides the combined supply of gas and power. In 2010, the program for expanding the combined integrated offer of gas and power progressed in accordance with the Company’s expansion plans.

In 2010, electricity sales increased by 16.4% to 39.54 TWh, driven by a slight recovery in electricity demand and growth in the client base, in particular the retail market following intensive marketing campaigns, and mainly related to higher sales on open-markets (up 2.74 TWh) benefiting from higher trading and higher volumes traded on the Italian power exchange (up 2.43 TWh).

In 2010, electricity sales (39.54 TWh) were directed to the free market (70%), the Italian power exchange (18%), industrial sites (8%) and others (4%).

> Planned Actions and Sales Target

> (i) Italy

Over the next four years, management plans to increase sales and regain market share in Italy by leveraging on the competitiveness of the Company’s cost position, and the quality of its offer, including the offer of pricing formulas and services that are designed to suit the customers’ needs. The Company intends to deploy tailored solutions and customized contracts to retain clients in the business segment, and expand its customer base in the retail segment by means of new marketing initiatives, the bundling of a range of valuable services to commercial offer and wider geographic presence through an integrated network of agencies and stores. Based on those actions, management targets to expand sales volumes in Italy by 12 BCM within 2014 and to regain market share. In the last quarter of 2010, the adoption of a more volume-oriented approach led to an increase in Italian sales and market share by an estimated 7% and 1.5 percentage points, respectively, compared to a 38.3% market share and 9.8 BCM sales for the fourth quarter of the previous year.

> (ii) European Markets

In Europe, the Company plans to increase sales volumes by 8 BCM by 2014 boosting direct sales in key European markets, particularly in France, Germany and Austria and maintaining its leadership position in the Benelux countries. To achieve these targets, management plans to leverage on the competitiveness of the Company’s cost position and new customized commercial offers, a multi-country approach and an integrated pan-European commercial platform.

A review of Eni’s presence in the key European markets is presented below.

59

##### Table of Contents

Benelux. Eni’s holds a leadership position in the Benelux countries (Belgium, the Netherlands and Luxembourg) granted by the integration with Distrigas’ operations and its significant exposure to spot markets in Western Europe. In 2010, Distrigas sales were mainly directed to industrial companies, wholesalers and power generation and amounted to 14.87 BCM from 2009, down 0.85 BCM, or 5.4%, due to rising competition. The Company plans to maintain steady sales in this region over the plan period.

France. Eni sells natural gas to industrial clients, wholesalers and power generation as well as to the segments of retail and middle market. Eni is present in the French market through its direct commercial activities and through its subsidiary Altergaz, in which the Company acquired a controlling interest by increasing its share to 55.2% in December 2010. Altergaz supplies approximately 119,800 clients, of which 104,000 are residential customers (69,000 in 2009, of which 58,000 residentials). Furthermore, Eni holds a 34% interest in Gaz de Bordeaux SAS (with a 17% direct interest and a further 17% held by Altergaz) which is engaged in selling natural gas in the Municipality of Bordeaux. Eni plans to develop this partnership. Management plans to expand sales in France over the plan period growing volumes supplied to the business segments and increasing retail customers leveraging on the Altergaz integration. In 2010, sales in France amounted to 6.09 BCM (4.91 BCM in 2009), an increase of 1.18 BCM, or 24%, from a year ago.

Germany-Austria. Eni is present in the German natural gas market through its associate GVS (Gasversorgung Süddeutschland GmbH - Eni 50%) which sold approximately 3.92 BCM in 2010 (1.96 BCM being Eni’s share), and through a direct marketing structure which sold in 2010 approximately 2.85 BCM in Germany and 1.09 BCM in Austria. Management plans to drive growth in direct sales leveraging on the quality of its commercial offer. In 2010, sales in Germany-Austria market amounted to 5.67 BCM, an increase of 0.31 BCM, or 5.8%, from a year ago.

> Iberian Peninsula

Portugal. Eni operates on the Portuguese market through its affiliate Galp Energia (Eni’s interest 33.34%) which sold approximately 5.10 BCM in 2010 (1.70 BCM being Eni’s share).

Spain. Eni operates in the Spanish gas market through a direct marketing structure that markets its portfolio of LNG and Unión Fenosa Gas (UFG) (Eni’s interest 50%) which mainly supplies natural gas to industrial clients, wholesalers and power generation utilities. In 2010, UFG gas sales in Europe amounted to 5.28 BCM (2.64 BCM Eni’s share). UFG holds an 80% interest in the Damietta liquefaction plant, on the Egyptian coast (see below), and a 7.36% interest in a liquefaction plant in Oman. In addition, it holds interests in the Sagunto (Valencia) and El Ferrol (Galicia) re-gasification plants (42.5% and 18.9%, respectively). In 2010, Eni sales in Spain amounted to 5.41 BCM representing a slight increase from a year ago. In 2010, total sales in the Iberian Peninsula amounted to 7.11 BCM, an increase of 0.30 BCM, or 4.4%, from a year ago.

Turkey. Eni sells gas supplied from Russia and transported via the Blue Stream pipeline. In 2010, sales amounted to 3.95 BCM, a decrease of 0.84 BCM, or 17.5% from a year ago.

UK/Northern Europe. Eni through its subsidiary North Sea Gas & Power (Eni UK Ltd) markets in the UK the equity gas produced at Eni’s fields in the North Sea and operates in the main continental natural gas hubs (NBP, Zeebrugge, TTF). In 2010, sales amounted to 5.22 BCM, an increase of 21.1% from a year ago.

Deborah Gas Storage Project in the Hewett area, UK. Eni has progressed in developing the Gas Storage Project on the Deborah field within the Hewett area located in the Southern Gas Basin in the North Sea, near the Bacton terminal, UK. The Deborah Gas Storage Project is designed to provide the UK and North Western Europe markets with 4.6 BCM of working gas. Eni, the single owner of the project, completed the Front End Engineering Design ("FEED") after an appraisal well had been successfully drilled, and obtained most of the permits requested to sanction the project from the relevant national and local authorities. At the end of 2010, a Capacity Allocation Process aiming at selling long-term storage capacity was launched. A number of market players participated to the process and Eni Hewett, the Eni affiliate managing the project, ensured long-term contractual commitments to sell more than 20% of the capacity. Some of the participants to the capacity allocation process show interest in getting a participation in the investment as well. Based on that, Eni Hewett is currently managing a process to sell equity participation in the Deborah Gas Storage project and is progressing in bilateral discussions to sell further gas storage capacity. FID is expected to be taken by end of 2011/beginning 2012 based on the outcome of the equity sale process and discussions on capacity sales.

> The LNG Business

Eni is present in all phases of the LNG business: liquefaction, shipping, re-gasification and sale through operated activities or interests in joint ventures and associates. Eni’s presence in the business is tied to the Company’s plans to develop its large gas reserve base in Africa and elsewhere in the world. The LNG business has been deeply impacted by the economic downturn of 2009 and structural modifications in the U.S. market where

60

##### Table of Contents

large availability of gas from unconventional sources have reduced the country’s dependence on gas imports via LNG.

Eni’s main assets and projects in the LNG business are described below.

Qatar. Though its subsidiary Distrigas, Eni increased its development opportunities in the LNG business with access to new supply sources mainly from Qatar, under a 20-year agreement with RasGas (owned by Qatar Petroleum with a 70% interest and ExxonMobil with a 30% interest) and the Zeebrugge LNG terminal on the Western coast of Belgium.

Egypt. Eni, through its interest in Unión Fenosa Gas, owns a 40% interest in the Damietta liquefaction plant with a capacity of approximately 5 mmtonnes/y of LNG which equates to a feedstock of 7.56 BCM/y in natural gas out of which the Gas & Power segment interest is up to 2.2 BCM/y to be marketed in Europe.

Spain. Eni through Unión Fenosa Gas holds a 21.25% interest in the Sagunto re-gasification plant, near Valencia, with a capacity of 8.8 BCM/y and a LNG storage capacity of 450,000 CM which will be increased to 600,000 CM after the ongoing construction of a fourth tank. At present, Eni’s re-gasification capacity entitlement amounts to 1.9 BCM/y of gas.

Eni through Unión Fenosa Gas also holds a 9.45% interest in the El Ferrol re-gasification plant, located in Galicia, with a treatment capacity of approximately 3.6 BCM/y, of which 0.34 BCM/y being Eni’s capacity entitlements. The LNG storage capacity of the plant is 300,000 CM in two tanks.

> USA

Cameron. The Cameron LNG terminal is situated 18 miles from the Gulf of Mexico along the Calcasieu Channel in Hackberry, Louisiana. The facility where Eni owns a capacity entitlement to treat LNG commenced operations in the third quarter of 2009. In consideration of a changed demand outlook for gas in the USA, on March 1, 2010, Eni renegotiated certain terms of the contract with the U.S. company Cameron LNG, owner of the facility, to farm out a share of the re-gasification capacity of the terminal. The new agreement provides that Eni is entitled to a daily send-out of 572,000 mmbtu (approximately 5.7 BCM/y) and a dedicated storage capacity of 160 KCM, giving Eni more flexibility in managing seasonal swings in gas demand. Furthermore, on March 3, 2011 Eni USA Gas Marketing Llc obtained from the American Department of Energy the authorization to export the LNG previously imported in the USA. This authorization will enhance operation flexibility, and will enable the company to exploit price differentials between American and European gas markets. Start-up of the Brass project (West Africa) to develop and liquefy gas reserves to fuel the Cameron plant is expected in 2016.

Pascagoula. This project is part of an upstream development project related to the construction of an LNG plant in Angola designed to produce 5.2 mmtonnes of LNG (approximately 7.3 BCM/y) destined to the North American market in order to monetize part of the Company’s gas reserves. As part of the downstream leg of the project, Eni signed a 20-year contract with Gulf LNG to buy 5.8 BCM/y of the re-gasification capacity of the plant under construction near Pascagoula in Mississippi. The start-up of the re-gasification facility is scheduled by the end of 2012 which is in line with the expected start-up of the upstream project in Angola.

At the same time Eni USA Gas Marketing Llc entered a 20-year contract for the purchase of approximately 0.9 BCM/y of re-gasified gas downstream the terminal owned by Angola Supply Services, a company whose partners also own Angola LNG.

In 2010, power generation was 25.63 TWh, up 1.54 TWh, or 6.4% from 2009, mainly due to higher production in particular at the Brindisi and Livorno plant.

As of December 31, 2010, installed operational capacity was 5.3 GW (5.3 GW in 2009).

Power availability in 2010 was supported by the growth in electricity trading activity (up 4.04 TWh, or 40.9%) due to higher volumes traded on the Italian power exchange benefiting from lower purchase prices.

By 2014, Eni intends to complete its plan for expanding its power generation capacity, targeting an installed operational capacity of 5.7 GW6.

At full capacity in 2014, production is expected to amount to approximately 29.2 TWh, corresponding to approximately 7.9% of power expected to be generated in Italy at that date.

This expansion will allow Eni to consolidate its market share and its position as the third largest power producer in Italy.

Supplies of natural gas are expected to amount to approximately 6 BCM/y from Eni’s diversified supply portfolio.

The power generation development plan is underway and mainly refers to: (i) the revamping at the recently acquired Bolgiano plant (Eni 100%); (ii) the upgrading at Taranto plant (Eni 100%); and (iii) the construction of a new bio-mass power generation plant at Eni’s Porto Torres industrial site which is currently under remediation.

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, using the CCGT technology instead of conventional power generation technology, the emission of carbon dioxide reduces by approximately 5 mmtonnes, on an energy production of 26.5 TWh. The CCGT technology has been acknowledged by the Authority for Electricity and Gas as a production technology that entails priority on the national dispatching network and the exemption from the purchase of "green certificates". Article 11 of Legislative Decree No. 79/1999 concerning the opening up of the Italian electricity market requires importers and producers of power from non renewable sources to input into the national power system a share of power produced from renewable sources set at 2% of power imported or produced from non renewable sources exceeding 100 GWh. Calculations are made on total amounts net of cogeneration and own consumption. This obligation can be met also by purchasing volumes or rights from other producers employing renewable sources (the so-called green certificates) to cover all or part of such 2% share. Legislative Decree No. 387/2003 provides that from 2004 to 2006 the minimum amount of power from renewable sources to be input in the grid in the following year be increased by 0.35% per year. The Minister of Productive Activities, with decrees issued in consent with the Minister for the Environment, has defined a 0.75% increase of this ratio for the periods from 2007 to 2010.

Eni’s main operated power plants are described below.

Ferrera Erbognone. This power plant has an installed capacity of approximately 1,030 MW divided between three combined cycle units, two of which have a capacity of approximately 390 MW and are fired with natural gas. The third unit has capacity of approximately 250 MW and is fired with a mixed fuel containing natural gas and refinery gas obtained from the gasification of a heavy residue from crude processing at the nearby Eni-operated Sannazzaro refinery.

Ravenna. Two new combined cycle units with the capacity of 390 MW each started operations in 2004. Adding to the existing capacity, the power plant’s installed capacity has reached a total of approximately 1,100 MW.

Brindisi. This power plant has been upgraded by installing three new combined cycle units, each with a capacity of 390 MW, which has increased the overall capacity to approximately 1,500 MW.

Mantova. This power plant has been upgraded by installing two new combined cycle units, each with a capacity of 390 MW, which has increased the overall capacity to approximately 900 MW. This power plant also provides steam for heating purposes delivered to the Mantova urban network through a heat exchanger.

> International Transport Activities

Eni owns capacity entitlements in an extensive network of international high pressure pipelines for a total length of approximately 4,400 kilometers enabling the Company to import natural gas produced in Russia, Algeria, the North Sea, including the Netherlands and Norway, and Libya to Italy. The Company invests in certain entities which own and operate those international pipelines, the pipeline owners, as well as in the entities which manage transportation rights, the carrier companies. For financial reporting purposes, such entities are either fully-consolidated or equity-accounted depending on the Company’s interest or agreements with other shareholders.

The structure of the Company’s interests in those entities may significantly change in the near future due to ongoing procedures for divesting Eni’s interests in the German TENP, the Swiss Transitgas and the Austrian TAG gas transport pipelines. The divestment is part of the commitments agreed upon by Eni and the European Commission to settle an antitrust proceeding related to alleged anti-competitive behavior in the natural gas market. In light of the strategic importance of the Austrian TAG pipeline to the supply of the Italian system, which transports gas from Russia to Italy, Eni negotiated a solution with the Commission which called for the transfer of its stake to an entity controlled by the Italian State. The Company expects to complete the divestment procedures within 2011. The prospected divestments will not affect Eni’s contractual gas transport rights.

A description of the main international pipelines participated or operated by Eni is provided below.

• |  | The TAG pipeline, 1,140-kilometer long, made up of three lines, each about 380-kilometer long, with a transport capacity of 37 BCM/y and five compression stations. This pipeline transports Russian natural gas from Baumgarten, the delivery point at the border of Austria and Slovakia, to Tarvisio, point of entry in the Italian natural gas transport system. In 2009, the upgrading of this facility was finalized by completing construction of two new compression stations that increased transport capacity by 6.5 BCM/y. The entire new capacity has been entirely awarded to third parties.
• |  | The TTPC pipeline, 740-kilometer long, made up of two lines that are each 370-kilometer long with a transport capacity of 33.2 BCM/y and five compression stations. This pipeline transports natural gas from Algeria across Tunisia from Oued Saf Saf at the Algerian border to Cap Bon on the Mediterranean coast where it links with the TMPC pipeline. The pipeline was recently upgraded by increasing compression capacity in order to enable transportation of an additional 6.5 BCM/y. The upgrade was finalized in 2008 and became fully-operational during 2009.
• |  | The TMPC pipeline for the import of Algerian gas is 775-kilometer long and consists of five lines that are each 155-kilometer long with a transport capacity of 33.5 BCM/y. It crosses the underwater Sicily Channel from Cap Bon to Mazara del Vallo in Sicily, the point of entry into the Italian natural gas transport system. In 2009, the operation of TMPC gas pipeline was fully-restored.
• |  | The TENP pipeline is 1,000-kilometer long (two 500-kilometer long lines) and has transport capacity of 15.5 BCM/y and four compression stations. It transports natural gas through Germany, from the German-Dutch border of Bocholtz to Wallbach at the German-Swiss border.
• |  | The Transitgas pipeline is 291-kilometer long and has one compression station, that transports natural gas across 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 transport capacity of 20 BCM/y. A new 55-kilometer long line from Oltingue/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. In July 2010, a large landslide interrupted the transportation through the Transitgas gas pipeline which was restored at the end of December 2010. Currently, a new variant of the trunkline is under construction with expected start-up by May 2011.
• |  | The GreenStream pipeline started operations in October 2004 for the import of Libyan gas produced at Eni operated fields Bahr Essalam and Wafa. It is 520-kilometer long with a transport capacity of 8 BCM/y and crosses underwater in the Mediterranean Sea from Mellitah on the Libyan coast to Gela in Sicily, the point of entry into the Italian natural gas transport system. In 2009, the pipeline was upgraded by 3 BCM/y, which is expected to come fully on stream in 2010, bringing total capacity to 11 BCM/y. In 2010 Eni divested a 25% stake in the company which operates the pipeline. See "Item 4 – Significant Business and Portfolio Developments" above. From February 22, 2011, in consideration of the current crisis in Libya, supplies of natural gas through the GreenStream pipeline have been suspended. Assets were not damaged and the abovementioned suspension does not affect Eni’s ability to fulfill its supply obligations with customers. For further details about this issue, see "Item 5 – Outlook".

Eni holds a 50% interest in the Blue Stream underwater pipeline (water depth greater than 2,150 meters) linking the Russian coast to the Turkish coast of the Black Sea. This pipeline is 774-kilometer long on two lines and has transport capacity of 16 BCM/y. It is part of a joint venture to sell gas produced in Russia on the Turkish market.

> The South Stream project

Eni and Gazprom are jointly assessing the technical and economic aspects of a project to build a new import route to Europe to market gas produced in Russia.

The South Stream pipeline will provide transport capacity of 63 BCM/y and is expected to be composed by two sections: (i) an offshore section crossing the Black Sea from the Russian coast at Beregovaya (the same starting point of the Blue Stream pipeline) to the Bulgarian coast at Varna; and (ii) an onshore section crossing Bulgaria for which two options are currently being evaluated: one pointing North West and another one pointing South West. The second option envisages crossing Greece and the Adriatic Sea before linking to the Italian network.

On June 18, 2010, Eni and Gazprom signed a Memorandum of Understanding to define terms and conditions for the French company EDF entering the South Stream project. As part of the agreement, EDF is expected to acquire an interest in the venture that is planning to build a new infrastructure to transport Russian gas across the Black Sea and Bulgaria to European markets.

Discussions among Eni, Gazprom and EdF in order to implement the latter’s accessions to the offshore section of the Project are ongoing.

> Regulated businesses in Italy

Over the medium-term, management intends to sustain the Company’s strategies by a selective capital expenditure plan focused in particular on the regulated businesses in Italy with guaranteed returns. Specifically, in the next four-year period Eni plans to invest approximately euro 7.5 billion in the Gas & Power segment of which euro 6.4 billion will mainly be devoted to: (i) expanding and upgrading transport networks in order to match the requirements of additional flexibility and security of the system. More than 80% of the total transport capital expenditures will continue to receive a 2% or 3% premium on the base allowed return; (ii) developing storage capacity by 4 BCM, according to government guidelines provided by Legislative Decree No. 130/2010 (for further information see below "Regulation of Eni’s Businesses – Gas & Power"), both through the development of new fields and the expansion of existing capacity; and (iii) upgrading and developing local distribution networks.

Eni, through Snam Rete Gas, a company listed on the Italian Stock Exchange, in which Eni holds a 52.54% interest, operates most of the Italian natural gas transport network, a re-gasification terminal located in Panigaglia, an extensive local distribution network and gas underground storage deposits and related facilities.

Management plans to invest approximately euro 6.4 billion in the next four years in the regulated businesses mainly directed to upgrading and developing the transport and distribution networks and storage capacity, aiming at strengthening security, flexibility and service quality of the gas infrastructures.

Specifically, in the next four-year period Eni plans to expand and upgrade transport networks, the storage regulated capacity, also in accordance with the requirements of Legislative Decree No. 130/2010, both through the development of new fields and the expansion of existing capacity, and upgrade and develop local distribution networks as well as to provide the substitution of old gas metering.

Eni, through Snam Rete Gas, operates the re-gasification terminal operating in Italy at Panigaglia (Liguria). At full capacity, this terminal can re-gasify 17,500 CM of LNG per day and input 3.5 BCM/y into the Italian transport network.

> Italian Transport Activity

Under Legislative Decree No. 164/2000 concerning the opening up of the natural gas market in Italy, transport and re-gasification 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 returns.

Eni’s network extends more than 31,600 kilometers and comprises: (i) a national transport network extending over 8,894 kilometers, made up of high pressure trunk-lines 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 regional transport networks. The national network includes also some interregional lines reaching important markets; and (ii) a regional transport network extending over 22,786 kilometers, made up of smaller lines and allowing the transport of natural gas to large industrial complexes, power stations and local distribution

In 2010, the LNG terminal in Panigaglia (La Spezia) re-gasified 1.98 BCM of natural gas (1.32 BCM in 2009).

> Distribution Activity

Distribution involves the delivery of natural gas to residential and commercial customers in urban centers through low pressure networks. The Company’s subsidiary Italgas and other subsidiaries operate in the distribution activity in Italy serving 1,330 municipalities through a low pressure network consisting of approximately 50,300 kilometers of pipelines supplying 5.8 million customers and distributing 8.15 BCM in 2010.

Under Legislative Decree No. 164/2000, distribution activities are considered a public service and therefore are regulated by the Authority for Electricity and Gas which determines the methods for calculating tariffs and fixing the return on capital employed. This business, therefore, presents low risk and a steady cash generation profile.

Distribution activities are conducted under concession agreements whereby local public administrations award the service of gas distribution to companies. According to Legislative Decree No. 164/2000, the award of the service has to take place by a competitive bid process from the end of a transition period no later than December 31, 2012. Future concessions will have a term as long as twelve years.

In particular, in the medium-term Eni intends to consolidate its presence in Italy, by increasing the profitability of its asset base, security across the network, and improve the service quality as well as efficiency of services rendered.

> Storage

The storage gas business in Italy is a fully-regulated activity which returns are preset by the Italian Authority for Electricity and Gas. Italian regulated storage services are provided through eight storage fields, based on ten storage concessions vested by the Ministry of Productive Activities, with a total modulation capacity of 9.2 BCM.

From the beginning of its operations, Stogit progressively increased the number of customers served and the share of revenues from third parties.

In 2010, storage capacity amounted to 14.2 BCM, of which 5 were destined to strategic storage.

The share of storage capacity used by third parties was 71% (70% in 2009).

> Capital Expenditures

See "Item 5 – Liquidity and Capital Resources – Capital Expenditures by Segment".

Refining & Marketing

Eni’s Refining & Marketing segment engages in the supply of crude oil, refining and marketing of refined products, trading and shipping of crude oil and product primarily in Italy and in Central-Eastern Europe. In Italy, Eni is the largest refining and marketing operator in terms of capacity and market share. The Company’s operations are fully-integrated through refining, supply, trading, logistics and marketing so as to maximize cost efficiencies and effectiveness of operations.

In 2010, the refining business was hit by a weak trading environment due to higher costs of oil-based feedstock that was not followed by a corresponding increase in product prices, pressured by weak demand, high inventories and excess refining capacity. In addition, the increased oil price triggered higher costs of energy utilities, which are typically indexed to it. However, those negative trends were more than offset by cost efficiencies, supply optimization, lower impairment and amortization charges and stable marketing results enabling the Company to achieve a significant improvement from the year-earlier results.

In the medium-term, management expects the trading environment in Europe to show limited improvements as demand for refined products will stagnate and excess capacity and high worldwide and regional inventory levels and product imbalances will persist on the marketplace. Although an overall reduction in refining capacity is expected. Management also warns against risks of further oil price increases.

To face expected negative trends in the refining scenario, Eni intends to focus on:

• |  | efficiency improvements mainly by achieving energy savings, reducing operating costs and streamlining logistic operations;
• |  | integration of refining cycles which will enable the Company to capture cost reductions or margin expansions; and
• |  | making selective capital projects to increase refining complexity.

In marketing, management plans to improve results by leveraging on better services to customers at Eni’s network of service stations, growing its market share in selective European markets and expanding the contribution to results from non-oil activities.

In the 2011-2014 period, we plan to make capital expenditures amounting to euro 2.9 billion, in line with the previous plan, carefully selecting capital projects. Management plans to invest approximately euro 2 billion to upgrade the Company’s best refineries mainly by completing and starting-up the EST (Eni Slurry Technology)

project at the Sannazzaro unit which will upgrade the conversion capacity of the refinery. In marketing, the Company intends to invest in retail network upgrading and rebranding and for developing non-oil activities.

As a result of all these actions, management believes that the Refining & Marketing segment will break-even in 2011 and then continue to improve profitability and cash generation, under the assumption that there will no improvement in the trading environment compared to 2010.

The matters regarding future plans discussed in this section and elsewhere herein are forward-looking statements that involve risks and uncertainties that could cause the actual results to differ materially from those in such forward-looking statements. Such risks and uncertainties include difficulties in obtaining approvals from relevant Antitrust Authorities and developments in the relevant market.

> Supply and Trading

In 2010, a total of 68.25 mmtonnes of crude were purchased by the Refining & Marketing Division (67.40 mmtonnes in 2009), of which 30.14 mmtonnes from Eni’s Exploration & Production Division. Volumes amounting to 20.95 mmtonnes were purchased on the spot market, while 17.16 mmtonnes were purchased under long-term supply contracts with producing countries. Approximately 25% of crude purchased in 2010 came from Russia, 22% from West Africa, 12% from the North Sea, 12% from the Middle East, 11% from North Africa, 5% from Italy, and 13% from other areas.

In 2010, some 36.17 mmtonnes of crude purchased were marketed (up of approximately 60 ktonnes, or 0.2%, from 2009). In addition, 3.05 mmtonnes of intermediate products were purchased (2.92 mmtonnes in 2009) to be used as feedstock in conversion plants and 15.28 mmtonnes of refined products (13.98 mmtonnes in 2009) were purchased to be sold on markets outside Italy (10.72 mmtonnes) and on the domestic market (4.56 mmtonnes) as a complement to available production.

> Refining

Against the backdrop of a weak outlook for refining margins, in the medium-term, management plans to improve profitability of the Company’s refining operations by focusing on operational efficiency through energy saving, streamlining logistics and fixed cost reductions. Integration actions of Eni’s refining system are expected to mainly target Gela and Taranto refineries enabling the Company to cut production of low value fuel oil and reduce supply costs. Management also intends to tightly control capital expenditure and selectively upgrade conversion capacity and flexibility of the best refineries.

As of December 31, 2010, Eni’s refining system had total refinery capacity (balanced with conversion capacity) of approximately 37.8 mmtonnes (equal to 757 KBBL/d) and a conversion index of 61%. The conversion index is a measure of a refinery complexity. The higher the index, the wider the spectrum of crude qualities and feedstock that a refinery is able to process thus enabling it to benefit from the cost economies which the Company generally expects to achieve as certain qualities of crude (particularly the heavy ones) may trade at discount with reference to the light crude Brent benchmark. Eni’s five 100-percent owned refineries have balanced capacity of 28.2 mmtonnes (equal to 564 KBBL/d), with a 65% conversion rate.

In 2010, refinery throughputs in Italy and outside Italy were 34.80 mmtonnes.

The Company plans to selectively upgrade its refining system by increasing complexity and flexibility at its best refineries. The main capital project will be the completion of a new conversion unit at the Sannazzaro refinery designed on the EST proprietary technology for converting the heavy barrel by almost eliminating residue from conversion processes. The start-up of this facility is confirmed to be 2012. Higher conversion capacity is expected to enable the Company to extract value from equity crude as well as capture opportunities of monetizing heavy crudes and non-conventional resources. Other projects will involve the enhancement of logistic infrastructures at the Taranto unit.

> 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 have operating and strategic features that aim at maximizing the value associated to the asset structure, the geographic positioning with respect to end markets and the integration with Eni’s other activities.

The Sannazzaro refinery has balanced refining capacity of 180 KBBL/d and a conversion index of 61.2%. Management believes that this unit is among the most efficient refineries in Europe. Located in the Po Valley, it mainly supplies markets in North-Western Italy and Switzerland. The high degree of flexibility and conversion capacity of this refinery allows it to process a wide range of feedstock. From a logistical standpoint this refinery is located along the route of the Central Europe Pipeline, which links the Genoa terminal with French speaking Switzerland. This refinery contains two primary distillation plants and relevant facilities, including three desulfurization units. Conversion is obtained through a fluid catalytic cracker (FCC), two hydrocrackers (HdCK), with the last unit entered into operations in June 2009, which enable middle distillate conversion and a visbreaking thermal conversion unit with a gasification facility using the heavy residue from visbreaking (tar) to produce syn-gas to feed the nearby EniPower power plant at Ferrera Erbognone. Eni is developing a conversion plant employing the Eni Slurry Technology with a 23 KBBL/d capacity for the processing of extra heavy crude with high sulfur content producing high quality middle distillates, in particular gasoil, and reducing the yield of fuel oil to zero. Start-up of this facility is scheduled in late 2012.

The Taranto refinery has balanced refining capacity of 120 KBBL/d and a conversion index of 72%. This refinery can process a wide range of crude and other feedstock. It principally produces fuels for automotive use and residential heating purposes for the Southern Italian markets. Besides its primary distillation plants and relevant facilities, including two units for the desulfurization of middle distillates, this refinery contains a two-stage thermal conversion plant (visbreaking/thermal cracking) and an RHU conversion plant for the conversion of high sulfur content residues into valuable products and catalytic 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 2010 a total of 1.8 mmtonnes of this oil were processed). A new hydro-cracking unit with a capacity of 17 KBBL/d started production in 2010 expanding the conversion capacity of the refinery.

The Gela refinery has balanced refining capacity of 100 KBBL/d and a conversion index of 142.4%. This refinery is located on the Southern coast of Sicily and is highly integrated with upstream operations as it processes heavy crude produced from Eni’s nearby offshore and onshore fields in Sicily. In addition, it is integrated downstream as it supplies large volumes of petrochemical feedstock to Eni’s in site petrochemical plants. The refinery also manufactures fuels for automotive use and petrochemical feedstock. Its high conversion level is ensured by an FCC unit with go-finer for the upgrading of feedstocks and two coking plants for the vacuum conversion of heavy residues. The power plant of this refinery also contains modern residue and exhaust fume treatment plants which allow full compliance with the tightest environmental standards. An upgrade of the Gela

##### Table of Contents

refinery is underway by means of an upgrade of its power plant, mainly through the revamping of its boilers, aimed at increasing profitability by exploiting the synergies deriving from the integration of refining and power generation.

The Livorno refinery, with balanced refining capacity of 84 KBBL/d and a conversion index of 11.4%, manufactures mainly gasoline, fuel oil for bunkering and lubricant bases. Besides its primary distillation plants, this refinery contains two lubricant manufacturing lines. Its pipeline links with the local harbor and with the Florence storage sites by means of two pipelines optimizes intake, handling and distribution of products.

The Porto Marghera refinery, with balanced refining capacity of 80 KBBL/d and a conversion index of 20.2%, this refinery supplies mainly markets in North-Eastern Italy and Austria. Besides its primary distillation plants, this refinery contains a two-stage thermal conversion plant (visbreaking/thermal cracking) designed to increase yields of valuable products.

> 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 included Vohburg and Neustadt refineries. Eni’s refining capacity in Germany amounts to approximately 60 KBBL/d mainly used to supply Eni’s distribution network in Bavaria and Eastern Germany.

Eni holds a 32.4% stake in Ceska Rafinerska, which includes two refineries, Kralupy and Litvinov, in the Czech Republic. Eni’s share of refining capacity amounts to about 53 KBBL/d.

In addition, through its 33.34% interest in Galp, Eni participates two refineries in Portugal: a small one in Porto specialized in the manufacture of lubricant bases and a larger and more complex refinery in Sines integrated with petrochemicals production.

The table below sets forth Eni’s petroleum products availability figures for the periods indicated.

optimization of refining cycles was implemented. In addition, higher volumes were processed due to the coming on stream of a new hydro-cracking unit in Taranto and lower planned standstills affected the partially-owned Milazzo refinery. These effects were partly offset by the termination of a process contract on the Saras third-party refinery (down 1,966 ktonnes). Eni’s refining throughputs outside Italy increased by 1.7% supported by higher refinery throughput in the Czech Republic as a consequence of increased margins and demand recovery.

Total throughputs in wholly-owned refineries were 25.70 mmtonnes, up by approximately 1.68 mmtonnes (or 7%) from 2009, reflecting an improved refinery utilization rate which reached 91%. This increase reflects feedstock integration in refinery cycles and improved throughput margins, in particular for lubricants.

Approximately 15.8% of volumes of processed crude was supplied by Eni’s Exploration & Production segment (16.3% in 2009) representing a 0.5 percentage point decrease from 2009, corresponding to a lower volume of approximately 90 ktonnes.

> Logistics

Eni is a primary operator in storage and transport of petroleum products in Italy with its logistical integrated infrastructure consisting of 21 directly managed storage sites and a network of petroleum product pipelines for the sale and storage of refined products, LPG and crude.

Eni’s logistic model is organized on hub structure including five main areas. These hubs monitor and centralize the handling of products flows aiming to drive forward more efficiency particularly in cost control of collection and delivery of orders.

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) by sea through spot and long-term lease contracts of tanker ships; and (ii) on land through the ownership of a pipeline network extending approximately 1,447 kilometer-long. Secondary distribution to retail and wholesale markets is effected through third parties who also own their means of transportation, in some instances with minority participation of Eni.

> Marketing

Eni markets a wide range of refined petroleum products, primarily in Italy, through an extensive operated network of service stations, franchises and other distribution systems.

In 2010, sales volumes of refined products (46.80 mmtonnes) were up of 1.21 mmtonnes from 2009, or 2.7%, mainly due to higher volumes sold to oil companies and traders in Italy and outside Italy.

> Retail Sales in Italy

The re-branding of Eni’s service stations and the upgrading of Eni’s retail network progressed in 2010. In 2010, 463 service stations in Italy were re-branded to the "eni" brand, corresponding to approximately 10% of the retail network, with priority awarded to high throughput service stations with non-oil activities.

In marketing operations, Eni plans to strengthen its competitive positioning in Italy and to expand sales of fuels and non-oil products as well as expanding its share in the domestic retail market for fuels by 2014, up from 30.4% in 2010. To achieve those results, management intends to upgrade the network of service stations by starting-up new outlets with high service standards, improve the quality and range of services offered to the Company’s customers in order to boost customer retention, enhancing the offer of premium products, and develop non-oil activities under the "eni" brand.

A strong focus will be devoted to pursue high levels of operating efficiency.

In 2010, retail sales in Italy of 8.63 mmtonnes decreased by approximately 400 ktonnes, down 4.4% driven by lower demand which mainly impacted gasoline and, to a lesser extent gasoil, reflecting a decline in domestic fuel demand, as well as rising competitive pressure and price elasticity. Average throughput related to gasoline and gasoil (2,322 kliters) decreased by approximately 160 kliters from 2009. Eni’s retail market share for 2010 was 30.4%, down 1.1 percentage point from 2009 (31.5%).

At December 31, 2010, Eni’s retail network in Italy consisted of 4,542 service stations, 68 more than at December 31, 2009 (4,474 service stations), resulting from the positive balance of acquisitions/releases of lease concessions (74 units), the opening of new service stations (11 units), partly offset by the closing of service stations with low throughput (13 units) and the release of 4 service stations under highway concession.

In 2010, also fuel sales of the Blu line – fuels with high performance and low environmental impact – recorded lower sales from 2009, reflecting weak domestic consumption. In particular, sales of BluDieselTech declined slightly down from 2009, approximately amounting to 573 ktonnes (689 mmliters), and represented 10.3% of gasoil sales on Eni’s retail network. At December 31, 2010, service stations marketing BluDieselTech totaled 4,071 units (4,104 at 2009 year end) covering approximately 90% of Eni’s network.

##### Table of Contents

Retail sales of BluSuper amounted to 70 ktonnes (approximately 94 mmliters), decreasing by approximately 12 ktonnes from 2009, and covered 2.6% of gasoline sales on Eni’s retail network (down 0.1% from a year ago). At December 31, 2010, service stations marketing BluSuper totaled 2,672 units (2,679 at December 31, 2009), covering approximately 59% of Eni’s network.

In February 2010, in replacement of the previous promotional campaign "You&Agip", Eni launched the new "you&eni" loyalty points program, which will last 3 years. This three-year long initiative offered prizes to customers in proportion to their purchases of fuels and convenience items through the accumulation of points on a loyalty card at service stations’ stores as well as at the ones of certain partners to the program. As of December 31, 2010, the number of customers that actively used the card in the year amounted to approximately 5 million. The average number of cards active each month was approximately 2.8 million. Volumes of fuel marketed under this initiative represented approximately 40% of overall volumes marketed on Eni’s network.

In 2010, the success of Eni’s "Iperself" promotional campaign continued. This promotion provides a discount to customers purchasing fuel in self-service stations during closing hours. Jointly with other marketing activities this initiative supported sales against the backdrop of a weak demand and increased price elasticity.

> Retail Sales in the Rest of Europe

Eni’s strategy in the rest of Europe is focused on selectively growing its market share, particularly Eastern and Central Europe leveraging on recent acquisitions in Austria and synergies ensured by the proximity of these markets to Eni’s production and logistic facilities, brand awareness and economies of scale.

In 2010, retail sales of refined products marketed in the rest of Europe (3.10 mmtonnes) were up 3.7% from 2009. The increase was driven by volume additions in Austria, reflecting the purchase of service stations, and by enhanced performance in Eastern Europe (particularly in Slovakia and Romania), as well as in Germany and France.

At December 31, 2010, Eni’s retail network in the rest of Europe consisted of 1,625 units, an increase of 113 units from December 31, 2009 (1,512 service stations). The network evolution was as follows: (i) positive balance of acquisitions/releases of lease concessions (19 units) with positive changes in Austria and Hungary; (ii) purchased 114 service stations; (iii) opened 5 new outlets; and (iv) 25 low throughput service stations were closed. Average throughput (2,441 kliters) slightly decreased from 2009 (2,461 kliters).

The key markets of Eni’s presence are: Austria with a 7% market share, Hungary with 11.9%, Czech Republic with 11.8%, Slovakia with 9.7%, Switzerland with 6.5% and Germany with a 3.4% on national base. These market shares were calculated by Eni based on public data on national consumption and Eni’s sales volumes.

Non-oil activities in the rest of Europe are carried out under the CiaoAgip® brand name in 1,146 service stations, of which 395 are in Germany and 173 in France, with a 71% coverage of the network and a virtually complete coverage of owned stations.

> Other businesses

> Wholesale

Eni markets gasoline and other fuels on the wholesale market in Italy, including diesel fuel for automotive use and for heating purposes, for agricultural vehicles and for vessels and fuel oil. Major customers are resellers, agricultural users, manufacturing industries, public utilities and transports, as well as final users (transporters, condominiums, farmers, fishers, etc.).

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 presence all over Italy and articulated in local marketing offices and a network of agents and concessionaires.

In 2010, sales volumes on wholesale markets in Italy (9.45 mmtonnes) were down by approximately 110 ktonnes from 2009, or 1.2%, mainly reflecting a decline in domestic consumption in particular of fuel oil by industrial customers. Eni’s wholesale market share for 2010 averaged 29.2%, up 1.6 percentage points from 2009 (27.6%).

74

##### Table of Contents

Sales on wholesale markets in the rest of Europe (3.88 mmtonnes) increased by approximately 220 ktonnes, or 6%, mainly in Austria, due to purchase of service stations, in France due to higher bitumen sales and in Germany, due to a large product availability and a recovery in consumption.

Supplies of feedstock to the petrochemical industry (1.72 mmtonnes) increased by approximately 390 ktonnes due to demand recovery.

Other sales (19.60 mmtonnes) increased by approximately 990 ktonnes, or 5.3%, mainly due to higher sales volumes to the cargo market and to oil companies.

Eni also markets jet fuel directly at 46 airports, of which 27 are in Italy. In 2010, these sales amounted to 1.8 mmtonnes (of which 1.4 mmtonnes are in Italy).

Eni is also active in the international market of bunkering, marketing marine fuel mainly in 40 ports, of which 23 are in Italy. In 2010, marine fuel sales were 2.03 mmtonnes (1.97 mmtonnes in Italy).

> LPG

In Italy, Eni is leader in LPG production, marketing and sale with 592 ktonnes sold for heating and automotive use equal to a 17.6% market share. An additional 217 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 5 bottling plants and 4 owned storage sites, in addition to products imported at coastal storage sites located in Livorno, Naples and Ravenna.

In order to expand its presence on the marketplace, in the medium-term Eni plans to increase the number of service stations providing dispensers for LPG for automotive use, targeting an increase market share to 26% by 2014.

> Lubricants

Eni operates seven (owned and co-owned) blending plants, in Italy, Europe, North and South America and the Far East. 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 leader in the manufacture and sale of lubricant bases. Base oils are manufactured primarily at Eni’s refinery in Livorno. Eni also owns one facility for the production of additives and solvents in Robassomero.

In 2010, retail and wholesale sales in Italy amounted to 106 ktonnes with a 24.1% 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 120 ktonnes, of these about 60% were registered in Europe (mainly Spain, Germany, and France).

> Oxygenates

Eni, through its subsidiary Ecofuel (Eni’s interest 100%), sells approximately 1.7 mmtonnes/y of oxygenates mainly ethers (approximately 6.5% of world demand) and methanol (approximately 1.1% of world demand). About 81% of products are manufactured in Italy in Eni’s plants in Ravenna, in Venezuela (in joint venture with Pequiven) and Saudi Arabia (in joint venture with Sabic) and the remaining 19% is bought and resold.

Eni also distributes bio-ETBE on the Italian market in compliance with the new legislation indicating the minimum content of bio-fuels. Bio-ETBE is a kind of MTBE that gained a relevant position in the formulation of gasoline in the European Union, due to the fact that it is produced from ethanol from agricultural crops and qualified as bio-component in the European directive on bio-fuels.

Starting from March 1, 2010, Italian regulation on bio-fuels content has been changed from 3% to 3.5%. With the use of Bio-ETBE and FAME Eni covered the compliance within 98%. From January 1, 2011, the content increases to 4%. Eni expects to cover compliance in the same manner as in 2010.

Petrochemicals

Eni operates in the businesses of olefins and aromatics, basic and intermediate products, polystyrene, elastomers and polyethylene. Its major production sites are located in Italy and Western Europe.

Eni’s strategy in its petrochemical business is to effectively and efficiently manage operations in order to lower the break-even considering the volatility of costs of oil-based feedstock, cyclicality in demand, strong competitive pressures from operators with lower cost structure, taking into account the commoditized nature of many of Eni’s products. In fact, Eni’s profitability in the petrochemical businesses is particularly sensitive to movements in product margins that are mainly affected by changes in oil-based feedstock costs and the speed at which product

##### Table of Contents

prices adjust to higher oil prices. See "Item 3 – Risk Factors". In 2010, the Petrochemicals Division trimmed operating losses from 2009 by improving demand, better products margins and cost efficiencies. Management expects the outlook for 2011 will be shaping favorably to the Company as the world economy strengthens thus boosting worldwide demand for chemical commodities. However, risks will persist due to rising oil prices which could put pressure on unit margins of commodities. In light of this, management is planning for actions intended to strengthen the product mix of the Company by developing new products characterized by higher value added than the current portfolio, particularly in the businesses of elastomers, polyethylene and styrenics. Further measures will be dedicated to reduce operating costs and improve yields and plant efficiency in the production of basic ethylene which is the primary input for all downstream productions. To target those objectives, management plans to make capital expenditures amounting to euro 1 billion over the next four-year period which will be mainly directed to develop the product line in the elastomer and polyethylene businesses, plant upgrading and revamping at the Company’s cracking units as well as complying with all applicable regulations on environment, health and safety issues. In addition, the Company plans to develop an initiative to produce plastics from certain bio-components at the Porto Torres unit in Sardinia, Italy. Other initiatives will involve marketing activities with the aim of boosting margins by sales channels optimization, product portfolio rationalization, including elimination of unprofitable products, and revision of pricing policies. Also licensing activities will be pursued in order to expand contribution to results from licensing the Company’s technologies. Based on those planned actions, management expects to improve profitability and cash flow of the Company’s petrochemicals operations targeting to break-even in 2012 under the Company’s assumption relating trends in the prices of crude oil. See "Item 5 – Outlook".

In 2010, sales of petrochemical products (4,731 ktonnes) increased by 466 ktonnes (or 10.9%) from 2009 as a result of a recovery in demand from the depressed levels experienced a year-earlier.

Petrochemical production (7,220 ktonnes) increased by 699 ktonnes from 2009, or 10.7% in all business areas driven by the needs to ensure supplies to meet recovery in sales volumes in all Eni’s main plants. In addition, the year earlier the Company was forced to shut down production during the course of the year in order to avoid accumulating excess of finished products.

In 2010, nominal production capacity decreased by one percentage point from 2009 due to the closing of the styrene plant in Hythe. The average plant utilization rate, calculated on nominal capacity increased from 65.4% to 72.9% as a result of higher volumes produced, in particular in the Priolo, Brindisi and Porto Torres plants.

Average unit sale prices increased by 35.6% from the depressed levels registered in 2009. The most relevant increase was registered in the average price of olefins (up 48% on average) driven by higher costs for oil-based feedstock (the virgin naphtha prices increased by 41% from a year ago) as demands for basic chemicals increased at a fast pace and supplies were constrained. Average unit prices of styrene and polyethylene increased on average by 30%, while elastomers achieved lower increases.

> Basic petrochemicals

Basic petrochemical revenues (euro 2,833 million) increased by euro 1,001 million (up 54.6%) from 2009 in all of the main business segments due to the steep increase in average unit prices (olefins up 48%; intermediates and aromatics up more than 30%) as a result of the pricing environment and higher volumes sold.

In particular, sales volumes of olefins increased by 17%, intermediates by 10%, while aromatics registered lower increases (up 8%) due to the decreases registered in xylene sales (down 5%).

Basic petrochemical production (4,860 ktonnes) increased by 510 ktonnes from 2009 (up 11.7%) due to the recovery in the demand for monomers.

> Polymers

Polymer revenues (euro 3,126 million) increased by euro 941 million from 2009 (up 43.1%) as unit prices increased by 30% on average. Sales volumes increased on average by 8% (elastomers up 11%, styrene up 10%, polyethylene up 6%) due to positive trends in demand.

Polymers production (2,360 ktonnes) increased by 189 ktonnes from 2009 (up 8.7%) driven by a recovery in the main end-markets (automotive, construction and packaging).

Production volumes of elastomers and styrene increased on average by 10% from 2009 due to higher production of EPR, nytrilic rubbers, compact polystyrene and ABS. Polyethylene production registered a lower increase (up 7.7%) due to unplanned facility downtime at the Dunkerque plant.

##### Table of Contents

> Seasonality

Eni’s results of operations reflect the seasonality in demand for natural gas and certain refined products used in residential space heating, the demand for which is typically highest in the first quarter of the year, which includes the coldest months and lowest in the third quarter, which includes the warmest months. Moreover, year-to-year comparability of results of operations is affected by weather conditions affecting demand for gas and other refined products in residential space heating. In colder years that are characterized by lower temperatures than historical average temperatures, demand for gas and products is typically higher than normal consumption patterns, and vice versa.

Research and Development

Technological research and development ("R&D") and continuous innovation represent key success factors in implementing Eni’s business strategies as they support our long-term competitive performance.

The Company believes that the oil industry has to face a number of challenges in the near future and that technology will play a vital role in helping it to effectively manage those challenges:

• |  | continuing uncertainty about the future evolution of prices and demand for oil and gas;
• |  | limited access to new hydrocarbon resources, with the consequent problems for production growth and reserve replacement;
• |  | growing interest for the development of unconventional resources; and
• |  | greater attention to operations safety in the aftermath of the recent accident in the Gulf of Mexico.

The reorganization of R&D structures that Eni started in 2006 was completed in 2010 with the help of some measures:

• |  | reorganization of the research projects portfolio aimed at focusing activity on industrial objectives while reducing time to completion. To this end, the total portfolio was reorganized by strategic themes with priority given to critical projects, thus achieving a balance between breakthrough research and technology upgrading. A new assessment system has been introduced which makes use of Key Performance Indicators (KPI) that allow to assess the tangible and intangible value generated by R&D and to monitor the management of projects;
• |  | new approach to the enhancement and management of intellectual property, based on the recognition of the value of patents generated by R&D activities;
• |  | launch of a cross-business project for operations safety in extreme environment, named "Effective control and mitigation of any well blow-out in super challenging environment";
• |  | enhancement of the program "Along with petroleum" which targets the exploitation of solar energy by means of polymeric plates acting as converters and concentrators of the solar spectrum, and the conversion of bio-mass from waste into bio-fuels by means of a liquefaction process that allows to convert organic waste into a bio-oil and the start-up of activities to develop a possible commercial application in the short-medium term; and
• |  | strengthening of strategic alliances and scientific cooperation projects with international academic institutions and research centers which we believe are qualified in the marketplace. As part of this, in 2008 we signed a research alliance with the Massachusetts Institute of Technology (MIT), Boston (USA), focused on innovative technology in the field of solar energy and in the Oil & Gas business. Within the alliance the Solar Frontiers Center (SFC) was inaugurated on May 4, 2010: a research center shared between MIT and Eni and wholly dedicated to R&D in solar energy. Other agreements were signed with the Milan and Turin Polytechnic universities and with the Italian National Research Center (CNR).

In 2010, Eni filed 88 patent applications (106 in 2009), 61 of these coming from Eni Divisions and Eni Corporate, 10 from Petrochemicals and 17 from the Engineering & Construction activities of Saipem. In particular, 8% of patents concerned refining processes, 49% were in the field of drilling and completion, geology/geophysics of fields and engineering, 8% concerned the environment and 35% concerned innovation on renewable energy sources. The efficacy and efficiency of intellectual property management and of know-how dissemination are monitored within the R&D performance assessment system. In 2010, a review of Eni’s patent portfolio was performed that ended with the decision to abandon obsolete and non profitable patents.

In 2010, Eni’s overall expenditure in R&D amounted to euro 221 million which were almost entirely expensed as incurred (euro 207 million in 2009 and euro 217 million in 2008).

At December 31, 2010, a total of 1,019 persons were employed in research and development activities (in line with 2009). Below, we describe the main results achieved in research and innovation for sustainability in 2010.

##### Table of Contents

In the next four-year period, Eni plans to spend euro 1.1 billion for technological research and innovation activities. Management believes that technological developments may ensure the Company a competitive advantages in the long-term.

A summary of the most relevant R&D results obtained during the year by each business segment and at a Corporation level is provided below.

> Exploration & Production

Advanced exploration techniques
- Reverse Time Migration (RTM). Emerging technology for the processing of in depth seismic data aimed at reconstructing the image of highly complex underground areas. In 2010, the proprietary version has been successfully applied for the first time to an exploration project in Angola, allowing the identification of new oil bearing structures that were not visible with conventional tools.
- Basin simulation (e-simbaTM). This proprietary package contains about 20 integrated software items for assessing the amount and type of hydrocarbons potentially trapped. In 2010, some of the functions have been developed and applied in about 30 exploration projects in countries such as Venezuela, Ghana, Mozambique, Poland Australia, Angola and Congo, allowing a better probabilistic assessment of mineral potential.

Drilling and completion technologies
- Extended reach drilling. Proprietary technology and equipment (Eni continuous circulation device, e-cdTM and aluminum rods) have been used to drill wells in China and Alaska. In China, costs were reduced by 50% as compared to earlier works.
- Innovative technologies to improve drilling safety. A portfolio of projects for increasing drilling safety reached an advanced stage with the in-field testing of special surface valves to be integrated in the proprietary equipment for an optimal drilling control (e-cdTM). An innovative system for blow-out control within the well (downhole blow-out isolation packer) has also been tested. In 2010, Eni continued the development of the Dual ROV assisted top kill system that provides an efficient technique for blow-outs in deepwater wells. The system will be introduced in the sea in 2011.

Technologies for field characterization and increase in recovery rates
- Polymer enhanced water injection. The design phase has been completed for the implementation of the project of polymer enhanced water injection in a well in Egypt. The study results suggest an approximately 3% increase in the recovery factor.
- Bright Water Injection. This technology is based on an additive that is injected in the ground and selectively blocks the rock parts where water is present, thus potentially increasing the extraction of crude from mature fields. It has been applied in 2010 in two fields in North Africa with positive results and further applications in Congo are scheduled for 2011.
- Tar recovery from tar sands. A mixed water-solvent process for obtaining high recovery rates from tar sands (>90% in weight as compared to tar contained in sands) has been developed and applied to different types of sand. A concept design study has been completed for facilities in a pilot plant for the testing of in situ recovery techniques.
- EOR with acoustic stimulation. This process is based on sending sound waves into a field through a mechanical lifting system designed for this purpose. In 2010, field tests in Egypt were made in order to assess the potential of this well known but little tested technology in controlled conditions. Early results indicated a positive effect on oil production in the mature field where the test was made.

> Refining & Marketing

Eni Slurry Technology (EST). The EST proprietary technology is an innovative process for hydro-conversion by means of a nanodispersed catalyst (slurry) and a peculiar process scheme to refine various kinds of heavy feedstock: residues from the distillation of heavy and extra-heavy crude (such as the ones from the Orinoco Belt in Venezuela) or non-conventional products such as tar sands, characterized by high contents of sulfur, nitrogen, metals, asphaltenes and other pollutants that are hard to manage in conventional refineries. EST does not produce by-products and completely converts feedstocks into distillates. In 2010, testing continued mainly directed to validating the technology from the point of view of the upgrading performance and plant management, and a customized basic on the Zuata crude was prepared. The first industrial plant with a 23 KBBL/d capacity is under construction at the Sannazzaro refinery, with start-up scheduled for 2012.

Hydrogen SCT-CPO (Short Contact Time - Catalytic Partial Oxidation). It is a reforming technology that can convert gaseous and liquid hydrocarbons (also derived from bio-mass) into synthetic gas (carbon monoxide and hydrogen). This technology can contribute to process intensification as it allows to produce synthetic gas and hydrogen using reactors up to 100 times smaller than those currently in use, with relevant savings. The development

of this technology, that makes use of oxygen enriched air, has been completed and another version making use of pure oxygen is under development.

Nanomaterials. The use of structured nanomaterials is one of the key elements for innovation and intensification of processes. Projects are underway to study and enhance nanomaterials that could introduce radical improvements in conversion processes. The Dual Catalyst Slurry technology is based on nanocatalysts and its current tests could lead to breakthrough developments in EST, as it can increase productivity and quality of end products. The development of a bi-functional catalyst is underway that hydrogenates and desulphorates feesdtocks and increases the cracking rate and nitrogen removal. In the Flexible FCC (fluid catalytic cracking), new proprietary zeolite and zeolite-like materials have been developed for increasing the conversion of heavier fractions without increasing residues. This additive, associated to a new process scheme could change the gasoline/gasoil ratio in favor of the latter. In 2010, application testing continued and confirmed the results obtained so that scale up has started with the aim of finding the final formulation to be used in industrial reactors. This application is covered by a patent application.

> Petrochemicals

Elastomers. A new grade of thermoplastic co-polymer has been industrially homologated to be used in adhesives with lower viscosity (remaining equal its adhesive/cohesive properties) leading to lower energy consumption in the formulation of the final adhesive. At a pilot scale, new hydrogenated styrene-butadiene co-polymers to be used as viscosity index improvers have been produced and are scheduled to be homologated by the reference customer. In the lab and pilot plant the advantage of using a new activator in the polymerization of terpolymers EPDM with vanadium based catalysts has been confirmed and provided higher yields, improved quality and lower consumption of chlorine in the production process.

Polyethylene. The production of two new grades of LLDPE (linear low density polyethylene) continued with wide distribution of molecular weight and therefore improved processability and retention of basic mechanic properties. In a gas phase plant a new grade of LLDPE for rotomolding application with exenes has been produced entailing a significant improvement of certain basic properties (such as resistance to chemicals). New formulas have been developed for HDPE (high density polyethylene) to be used in rotomolding applications in the field of phytochemicals.

Styrenic polymers. A new formula of ABS (acrylonitryl-butadiene-styrene polymer) grade from continuous mass has been developed for injection molding. This formula dramatically increases the mechanical properties of products adjusting their performance to products deriving from emulsions. This allows a relevant recovery in penetration into injection molding. After the first industrial campaign, customers expressed their satisfaction.

> Engineering & Construction

Assets
Technological innovation on assets is pursued with the aim of improving sustainability, competition and reliability, and reducing the environmental impact of operations. In particular, in 2010 some of the projects underway reached the testing phase:

• |  | Equipment. New systems for the construction of coverage for soldering joints on board of pipelaying vessels, techniques for the remote control of anomalous deformations during the laying of pipes into the sea and some technologies complementary to excavation activities for critical operating scenarios have been validated. Studies were completed on technologies for the sustainability of construction of infrastructure in environmentally highly sensitive areas.
• |  | Vessels. Detailed development and implementation of the main technical systems and subsystems for production and laying of pipes on the new pipelaying vessel CastorOne continued.

Offshore
Activities were focused on programs dedicated to the continued improvement of innovative solutions for the development of oil and natural gas fields in the sea. Main activities concerned fields in frontier areas such as deep waters and the Arctic, monetization of offshore natural gas reserves by means of liquefaction technologies applied on floating plants (LNG offshore) and production from offshore renewable sources:

• |  | Subsea processing. A new proprietary multi-pipe system for the gravitational separation of gas and liquids successfully completed the second testing phase in the framework of a Joint Industry Project supported by important oil companies. Results achieved confirmed the efficacy of the separator in real flow conditions.

• |  | SURF. Activities started in 2009 on projects for developing solutions for new risers to be used in ultra-deep (up to 3,000 meters) or intermediate depth (between 300 and 600 meters) waters continued. Work continued on technologies for thermal isolation and anticorrosion solutions for underwater operations.
• |  | Offshore renewable sources. Activities focus mainly on a large scale prototype of an underwater turbine with 10-meter diameter called Sabella to be installed in the future off the coast of Brittany. The participation of the French Government to the financing of the project was officially announced at the end of 2010.

Onshore
Activity is dedicated to process technologies and their know-how and to the application of the most modern and state-of-the-art technologies from third parties supporting our clients worldwide in the upstream, midstream and downstream areas in the various phases of completion from engineering to construction.

• |  | Urea plants. Work was aimed at increasing the performance of our Snamprogetti™ Urea proprietary technology for the production of fertilizers, licensed worldwide and applied to date in 120 plants. After having planned and in some cases also built the largest urea plants in the world (Engro in Pakistan, Qafco V and VI in Qatar and Matix in India) based on the operation of single lines for 3,859 tonnes/d, we developed a conceptual study for a future 5,000 tonnes/d train using the same well-established sequence of technologies. In addition, we are designing a pilot unit for the recovery of ammonia within the Zero emission project that will be then built in a commercial plant.
• |  | CCS. Within the Eni/Enel pilot program on Carbon Capture and Storage, Saipem is following the design of a pipe for carrying dense CO2. We completed the project phase of a line for pilot transport to be located in the Brindisi power station.
• |  | ENSOLVEX. The first commercial unit based on this proprietary technology for the remediation of contaminated soil is under construction at the Gela refinery.
• |  | Microalgae. The first semicommercial unit for removing carbon dioxide from refinery effluents through bio-fixation by means of microalgae was completed and delivered. The ensuing bio-mass can be used for the production of bio-fuels.
• |  | Sulfur treatment. Saipem obtained a new patent for the technology for the treatment and transport of sulfur with zero emissions, a new method for solidifying liquid sulfur in blocks, thus consolidating its first class position in sulfur treatment technologies.

An overview of the main research projects developed during the year at the Corporate level is provided below.

Cube. To cope with events similar to that occurred at the Macondo well in the Gulf of Mexico and the failed attempt to collect the crude plume with a containing device, Eni prepared a device (in 1:4 proportion) for the collection and separation of gas from water and oil near the wellhead on the seabed and tested it in-house up to a flow of 10,000 BBL/d.

Development of reaction capacity to oil spills on the coast of the Barents Sea and sub-Arctic areas. The Norwegian project led by Eni achieved relevant results in 2010 in preparing an emergency plan for the Goliat field in the Barents Sea. Standards for testing disperdents and beach cleaners have been developed in order to use them in case of oil spills near the coast. These standards will be upheld by Norwegian law and later suggested at international level.

GHG program (Green House Gases). Activities are progressing part of the pilot project for injecting CO2 in the Cortemaggiore gas storage site. Authorizations are pending to build and operate the plant.

Water management. This project promotes the application of innovative technologies for the treatment of reinjected waters. In 2010, the contract for the supply of a system for the removal of oil and solids from production waters in the Egyptian Desert has been awarded.

Organic Rankine Cycle (ORC) Technology for Energy Recovery. A feasibility study has been completed and the installation of Organic Fluid Cycle is underway in the gas powered Fano power station (3 MW) by recovering the thermal power dissipated by turbocompressors. This would represent the first application of the ORC technique to Eni’s Group.

Feeding pumps in desert areas with photovoltaic devices. A contract has been prepared and the engineering is underway for a the supply of photovoltaic systems to be applied onto diesel generators for feeding sucker rod pumps in desert areas in Egypt.

Transport of carbon dioxide by pipeline (TACC). This project is part of the program of long distance transport of gases under different pressures with the aim of developing standards, guidelines and recommendations for future applications in carbon capture and storage. In 2010, the technical part of the program was laid out as well as the participants in the joint industrial project. Eni will promote the creation of JIP action with other integrated gas companies, e.g. Gasunie and Statoil.

Monitoring of advanced gas transport systems (MAST and Dionisio project). Eni has developed proprietary technologies for the advanced monitoring of gas transport systems (pipelines and compression stations). In 2010, technologies have been successfully tested for the identification of structural defaults (MAST) that can generate criticalities in transport. The development of the Dionisio technology that is based on vibro-acoustic sensors for noticing intrusions and leaks along transport pipelines continued. A prototype monitoring system has been installed on the Chivasso-Aosta pipeline.

> Refining & Marketing Division

Blu fuels and products. Eni has been working for years in R&D for advanced fuels and lubricants that aim at optimizing engine efficiency and reducing noxious emissions. In February 2010, the Lombardia Region and Eni signed an agreement for the distribution of "formula Milano" in 50 outlets. This is a type of BluDieselTech with: (i) a total aromatics content lower than 18% in weight, as compared to an average 25% currently on sale; (ii) a total polyaromatics content lower 3% in weight as compared to an average 8%; and (iii) cetane number >55 as compared to current standards providing for a minimum 51.

Biofuels. Eni developed the Ecofining™ technology in cooperation with UOP that allows for the conversion of vegetables into Green Diesel. In November 2010, the American Institute of Chemical Engineers (AICHE) awarded Eni and UOP the 2010 Sustainable Energy Award for the activities developed in this area. Aim of the Ecofining™ technology is the production of bio-fuel by means of an integrated refining process that allows for the hydrotreatment of the renewable portion (vegetable oil, exhausted oil, animal fat) and obtain a superior product in terms of heating value and cetane number than conventional bio-diesel (FAME).

Zero waste. Eni intends to develop a system for the disposal of industrial sludge alternative to landfills, possibly associated to thermal treatment in order to minimize waste. For the treatment of industrial, oily and biological waste generated by the oil industry a thermal process has been studied that allows for the gasification of sludge that is turned into an inert residue. A patent application has been filed on this project. Basic design has been completed of a pilot plant with a 50 kg/h capacity along with a feasibility study for an annual volume of 5,000 tonnes of sludge.

> Polimeri Europa

Basic petrochemicals. Positive testing of catalytic oxidation of phenilcyclohexane on a pilot plant was performed as part of a study aiming at completing a proprietary process for the direct production of phenol and cyclohexanone, which uses benzene as sole feedstock, eliminating the production of acetone as by-product (a toxic and flammable fluid).

Elastomers. The first industrial production of new grades of SBR (styrene-butadiene rubber) has been completed with application to high performance (lower energy consumption and reduction in resistance to rolling) in tire materials. In the lab Eni developed a proprietary technology for new grades of elastomers for Tyre Green application (with lower emissions) with even better performance. ESBR and NBR rubber grades have been obtained at industrial level with low VOCs content.

Styrenic polymers. At the Mantova site, in the new patented technology plant for the expandable polystyrene production, the industrialization of expandable polystyrene was successfully completed through a continuous mass system with a 38 ktonnes/y capacity. The new products allow a 15% reduction in VOCs which are released in the atmosphere during transformation.

##### Table of Contents

radiation is partially concentrated within the slab by total internal reflections and is waveguided toward its edges where PV cells are placed. LSCs allow for a substantial decrease in standard PV module costs by reducing the effective cell surface with respect to the absorbing surface. The positive results obtained at lab level allow the commencement of a pre-commercial phase.

Use of waste for energy production. At lab scale Eni developed a "liquefaction" process for the conversion of the organic waste into bio-oil with a nearly 42% yield (on dry weight) corresponding to an 80% energy recovery. This new technology has been patented and successfully applied to the organic fraction of solid urban waste (FORSU) and to sludge from waste purification plants.

Micro-organisms for bio-diesel. Purpose of the project is the use of micro-organisms (yeasts and bacteria) that accumulate lipids similar to those deriving from oil-bearing vegetables, that can easily be turned into bio-diesel. The raw material employed by these micro-organisms derives from the treatment of wood-cellulose bio-mass in order to not compete with food products. The identified yeasts have higher productivity than the traditional oil crops, including palm.

EKRT (ElectroKinetic Remediation Technology). It is a technology for environmental remediation applicable to mercury polluted soils. An electrolytic solution is circulated in order to dissolve the metallic part of mercury, separating it by means of electro kinesis. This process does not affect the inert portions of mercury and acts selectively only on the mobile portion of mercury, that is also its toxic portion.

> Results derived from the Eni-MIT alliance

Oil spills in marine environment. The project derives from the discovery of an innovative material with great selective capacity for the absorption of oil dispersed in water. This could be a first step towards new systems for treating oil spills in marine environments.

Ultraflexible solar cell. One of the most relevant results obtained by the Solar Frontier Center: these cells made of a thin photoactive material covered by a layer of transparent plastic can be bent without breaking or reducing performance and this allows to cover irregular surfaces without using metal stilts.

Solar cells on paper. In this case the photoactive device is made on paper as a printed document. The innovative technique is the same used for producing cells on plastic and flexible substrata. A paper cell can be a low cost solution for application where the key aspect is not duration but fast installation and easy transport.

Photochemical splitting of water. Aim of this project is to devise processes for generating oxygen and hydrogen from water by means of biological agents using solar light. The main actors here are nanomaterials synthesized by exploiting the self-assembling capacity of viruses. With this technique we proceeded with the synthesis of new active materials that can be useful in promoting a sustainable generation of hydrogen from renewable sources.

Biofixation of CO2. CO2 in the sea is captured by living organisms that convert it into calcium carbonate that is a component of their shell. These biological systems have been successfully reproduced in the lab with the use of yeasts. This paves the way for exploiting CO2 while producing calcium carbonate and other materials that are considered eco-friendly.

Insurance

In order to control the insurance costs incurred by each of Eni’s business units, the Company constantly assesses its risk exposure in both Italian and foreign activities. The Company has established a subsidiary, Eni Insurance Ltd, in order to efficiently manage transactions with mutual entities and third parties providing insurance policies. Internal insurance risk managers work in close contact with business units in order to assess potential underlying business and other type of risks and possible financial impact on the Group results of operations and liquidity. This process allows Eni to accept risks in consideration of results of technical and risk mitigation standards and practices, to define the appropriate level of risk retention and, finally, the amount of risk to be transferred to the market.

86

##### Table of Contents

Eni enters into insurance arrangements through its shareholding in the OIL Insurance Ltd ("OIL") and with other insurance partners in order to limit possible economic impacts associated with damages to both third parties and the environment occurring in case of both onshore and offshore accidents. The main part of this insurance portfolio is related to operating risks associated with oil and gas operations which are insured making use of insurance policies provided by the OIL, a mutual insurance and re-insurance company that provides its members a broad coverage of insurance services tailored to the specific requirements of oil and energy companies. In addition, Eni makes recourse to insurance companies who we believe are established on the marketplace. Insured liabilities vary depending on the nature and type of circumstances; however underlying amounts represent significant shares of the plafond granted by insuring companies. In particular, in the case of oil spills and other environmental damage, current insurance policies cover costs of cleaning-up and remediating polluted sites, damage to third parties and containment of physical damage up to $1.1 billion for offshore events and $1.5 billion for onshore plants (refineries). These are complemented by insurance policies that cover owners, operators and renters of vessels with the following maximum amounts: $1 billion for the fleet owned by the subsidiary LNG Shipping in the Gas & Power segment and FPSOs used by the Exploration & Production segment for developing offshore fields; $500 million for time charters.

Management believes that the level of insurance maintained by Eni is generally appropriate for the risks of its businesses.

Environmental Matters

> Environmental Regulation

Eni is subject to numerous EU, international, national, regional and local environmental, health and safety 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, provide for measures to be taken to protect the safety of the workplace and health of communities affected by the company’s activities, 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, petrochemical plants, refineries, pipeline systems and other facilities that Eni owns. In addition, Eni’s operations are subject to laws and regulations relating to the production, 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 certain operations and products of Eni, and there can be no assurance that material costs and liabilities will not be incurred.

A brief description of major environmental laws impacting Eni’s activities located in Italy and Europe is outlined below.

> Italy

On April 29, 2006, Legislative Decree No. 152/2006 "Environment Regulation" came into force. This was designed to rationalize and coordinate the whole regulation of environmental matters by setting:

• |  | procedures for Strategic Environment Assessment (SEA), Environmental Impact Assessment (EIA) and Integrated Pollution Prevention and Pollution Control (IPPC);
• |  | procedures to preserve soil, prevent desertification, effectively manage water resources and protect water from pollution;
• |  | procedures to effectively manage waste and remediate contaminated sites;
• |  | air protection and reduction of atmospheric pollution; and
• |  | environmental liability.

The most important changes introduced by the Decree regarded reclamation and remediation activities as this Decree provided a site-specific risk-based approach to determine objectives of reclamation and remediation projects, cost-effective analysis required to evaluate remediation solutions, and criteria for waste classification.

Decree No. 152/2006 was amended by four subsequent decrees: Legislative Decrees No. 284/2006, No. 4/2008, No. 128/2010 and No. 205/2010.

87

##### Table of Contents

Decree No. 4/2008 introduced important changes regarding SEA and EIA procedures, landfill, waste and remediation. The most important aspects of these regulations to Eni are those regulating permits for industrial activities, waste management, and remediation of polluted sites, water protection and environmental liability.

Decree No. 128/2010 introduced IPPC regulations and additional restricting emission limits for certain critical pollutants, in compliance with the IED directive. In relation to the accident occurred in the Gulf of Mexico, the Decree also introduced permit restrictions regarding offshore activities, in line with the European Parliament Resolution of October 7, 2010 on EU action on oil exploration and extraction in Europe. Eni is planning to reschedule certain offshore activities in the Mediterranean Sea and the North European Sea to take account of such developments.

Decree No. 205/2010 implemented the Directive No. 2008/98/EC about waste and adopted the new Special Waste Tracking System (SISTRI) aimed to track waste transfers at national level and to allow a real-time control by authorities. The full operability of the system, initially forecasted by July 2010, has been rescheduled to June 2011.

Decree No. 155/2010 adopted in the Italian law, the European prescriptions on ambient air quality, established by the Directive No. 2008/50/EC. Its main innovation is the definition of monitoring criteria and emission limits for fine particulate substances (PM 2.5), to be achieved by January 1, 2015.

Legislative Decree No. 81/2008 concerned the protection of health and safety in the work place and was designed to regulate the work environments, equipments and individual protection devices, physical agents (noise, mechanical vibrations, electromagnetic fields, optical radiations, etc.), dangerous substances (chemical agents, carcinogenic substances, etc.), biological agents and explosive atmosphere, the system of signs, video terminals. Eni worked on the implementation of the general framework regulations on health and safety concerning prevention and protection of workers at national and European level to be applied to all kinds of workers and employees.

At the European level, Eni continued its work for applying the REACH Regulation (Registration, Evaluation, Authorization and Restriction of Chemicals, EC Regulation No. 197/2006).

The complexity and range of situations where Eni is operating imposed the definition and application of principles for consolidating its performance in health and prevention. To this end Eni upholds:

• |  | clear policies;
• |  | an ethical code;
• |  | endorsement of international conventions and principles;
• |  | guidelines and procedures; and
• |  | sharing of knowledge.

> European Union

The European Commission has put forward its new Energy Policy for Europe - EPE, so-called "20-20 by 2020", a far-reaching package of proposals that will deliver on the European Union’s ambitious commitments to fight climate change, promote renewable energy and increase energy security. The following regulations were published in order to define the criteria for cutting emissions cost-effectively by 2020 compared with levels in 2005:

• |  | Directive No. 2009/28/EC: fixing target of 20% share of energy from renewable sources in 2020. It creates cooperation mechanisms so that the EU can achieve the targets in a cost effective way. It also includes a flat 10% target for renewables in transport (bio-fuels, "green" electricity, etc.); this legislation also sets out sustainability criteria that bio-fuels should meet to ensure they deliver real environmental benefits.
• |  | Directive No. 2009/29/EC: improves and extends to the third phase (2013-2020) the greenhouse gas emission allowance trading scheme of the European Community to provide for a more efficient, homogeneous and fair system. It defines criteria and targets for cutting GHG emissions from the sectors covered by the system (energy and manufacturing industries) by 21% by 2020 compared with levels in 2005. The Auctioning Regulation contains a set of rules for the auctioning processes that should be undertaken for the auction of allowances from 2013. On December 14, 2010, Climate Change Committee voted the benchmark decision, which describes the rules for the free allocation from 2013.
• |  | Directive No. 2009/30/EC: defines the fuel quality and places an obligation on suppliers to reduce greenhouse gases from the entire fuel life cycle of 6% by 2020, mostly by an increased use of bio-fuels.
• |  | Directive No. 2009/31/EC: defines a scenario in order to promote the development and safe use of Carbon Capture & Storage (CCS), a suite of technologies that allows the carbon dioxide emitted by industrial processes to be captured and stored underground.
• |  | Regulation 443/2009/CE: sets emissions standards for new passenger cars and targets a reduction to an average of 120 g CO2/km by 2015, decreasing to a stringent long-term target of 95 g CO2/km by 2020.
• |  | Decision 406/2009/CE: defines, for sectors not included in the EU ETS, such as transport, housing, agriculture and waste, emissions reduction target of 10% from 2005 levels by 2020 (the Italian reduction target is fixed at 13%).

##### Table of Contents

Directive No. 2008/1/EC contains the new IPPC and rationalizes all existing regulations on this issue. member states of the EU have to communicate their national values of emissions into the atmosphere, wastes produced and managed and discharges of compounds into waste that are to be included in the European Pollutant Release and Transfer Register (E-PRTR). According to the E-PRTR, Eni installations shall report data on the Italian Register website, by the end of March of each year.

In 2010, Eni has completed the implementation of an Integrated Environmental Information System, able to gather, manage and report the data on all the pollutants released and off-site transferred as requested by PRTR Regulations.

On December 21, 2007, the European Commission published its proposal of directive on Industrial Emissions. In view of the general call for "better regulation", the draft incorporates the review of six sector-specific directives (IPPC, Large Combustion Plants, VOC – Volatile Organic Compounds – emissions, incineration of waste and titanium industry). The proposed directive intends to enforce BAT definition, together with a tightening of current minimum emission values in some sectors. The new proposal also introduces more robust monitoring and inspections on installations, the review of permit conditions and the reporting of compliance. The proposal reached the final reading phase on July 7, 2010 and the directive was formally adopted on October 25, 2010 and expected to be published by 2011. The directive defines more restricting emission limits to be observed by the end of 2012, although includes some derogation, as the TNP Transitional National Plan and the option Opt-Out for those installations that are going to shut down their operations by 2023. The member states must transpose the Directive into national legislation by 24 months from publication.

Moreover in September 2010, the European Commission started a public internet consultation on the Review of the Environmental Impact Assessment (EIA) Directive (Directive No. 85/337/EC on the assessment of the effects of certain public and private projects on the environment, as amended). The objective of this public consultation is to collect opinions on the overall view on the functioning and effectiveness of the EIA Directive and possible areas to be improved/amended. Eni participates to the consultation, answering the web-questionnaire.

On November 22, 2008, the new directive on waste (Directive No. 2008/98/EC) was published in the Official Journal of the European Union. The new directive simplifies the existing legislative framework by clarifying definitions, streamlining provisions and integrating the directives on hazardous waste (No. 1991/689/EC) and on waste oils (No. 1975/439/EC). The directive introduces a life-cycle approach, focuses on waste policy by improving the way of resources consumption. The scope is to improve the recycling market by setting environmental standards, specifying under which conditions certain recycled waste are no longer considered such. The directive requires that member states take appropriate measures to encourage the prevention or reduction of waste production and its harmfulness. This can be done by a combination of several strategies particularly through the development of clean technologies, the technical development and marketing of products designed so to contribute as little as possible to increasing the amount of waste. The directive also sets new recycling targets.

The core of the directive is the introduction of a waste management hierarchy. This hierarchy is as follows: 1. Waste prevention, 2. Re-use, 3. Recycling, 4. Recovery (including energy recovery), 5. Disposal.

Moreover the directive bolsters the importance of the extended producer responsibility in the future waste management measures.

The promising results of the UN Conference of Cancun (December 2010) related to the definition of a Climate Agreement after 2012, have led the European Commission, on March 15, 2011, to present a Roadmap for transforming the European Union into the worldwide forerunner of low carbon economy by 2050. The Roadmap objective is cutting greenhouse gas emissions by 80-95% of 1990 levels within 2050, by implementing cost-effective measures aiming mostly at improving energy efficiency. The analysis takes into consideration costs and savings related to potential measures such as sectoral policies, national and regional low-carbon strategies and long-term investments. The Commission’s analysis shows that the global transition to a low carbon and resource-efficient economy will generate multiple benefits for the EU: energy importation costs savings, improvements in energy security and economy competitiveness.

Following the incident at the Macondo well in the Gulf of Mexico the U.S. Government and other governments have adopted or are likely to adopt more stringent regulations targeting safety and reliable oil and gas operations in the USA and elsewhere, particularly relating to environmental and health and safety protection controls and oversight of drilling operations, as well as access to new drilling areas. The U.S. Government imposed a moratorium on certain offshore drilling activities through November 30, 2010 (it was suspended in October), and similar actions may be taken by governments elsewhere in the world. Confirming this approach, Italian Authorities have passed legislation with Law Decree No. 128 on June 29, 2010 that introduces certain restrictions to activities for exploring and producing hydrocarbons; however existing projects for conducting oil and gas operation would not be affected. Eni and other operators in the industry have commenced discussions with the Italian Ministry for Economic Development and the Ministry for the Environment to clarify uncertainties in correctly interpreting and applying the new regulations.

##### Table of Contents

Also the European Parliament has increased its activities in the area of environmental protection in the field of hydrocarbon extraction. On October 7, 2010 the European Parliament approved a resolution on this issue and rejected a proposed moratorium on new oil platforms until global adoption of uniformly more stringent environmental protection laws. The resolution highlighted need for a single European system for prevention and response to intra-community oil spills which would entail amending three EU directives: Seveso II, the directive on environmental responsibility and VIA. The Italian Government confirmed its intention to harmonize Italian laws with European laws also according to the approved resolution. Adoption of stricter regulation both at national and European or international level and expected evolution in industrial practices could trigger cost increases to comply with new HSE standards which the Company might adopt either on a mandatory or voluntary basis. Also our exploration and development plans to produce hydrocarbons reserves and drilling programs could be affected by changing HSE regulations and industrial practices. Lastly, the Company expects that production royalties and income taxes in the oil and gas industry will likely increase compared to previous years. The assessments made by Eni’s management regarding the impacts on our operations following the Macondo well incident in the Gulf of Mexico and the rescheduling of certain projects due to the moratorium called by the U.S. Government caused delays in linking few wells to production facilities which had a negligible impact on the Company’s production for the year. In addition, the Group incurred operating costs related to inactivity or redeployment of certain drilling rigs which were booked before the moratorium. During the first months of 2011, Eni expects to resume the operations that had been previously authorized and suspended following the moratorium. Planned activities for which authorizations still have to be granted might be rescheduled due to uncertainties in the timing of obtaining the necessary authorizations from the U.S. Authorities. In order to achieve the highest security standards of our operations in the Gulf of Mexico, we entered into a consortium led by Helix that worked at the containment of the oil spill at the Macondo well. The Helix Fast Response System (HFRS) performs certain activities associated with underwater containment of erupting wells, evacuation of hydrocarbon on the sea surface, storage and transport to the coastline.

> HSE Activity for the Year 2010

Eni is committed to continuously improve its model for managing health, safety and environment across all its businesses in order to minimize risks associated with its industrial activities, ensure reliability of its industrial operations and comply with all applicable rules and regulations.

In 2010, Eni’s business units continued to obtain certifications of their management systems, industrial installations and operating units according to the most stringent international standards. The total number of certifications achieved was 271 (247 in 2009), of which 97 certifications according to the ISO 14001 standard, 9 certifications according to the EMAS regulation (EMAS is the Environmental Management and Audit Scheme recognized by the European Union) and 62 according to the OHSAS 18001 standard (Occupational Health and Safety management Systems - requirements).

Environment. In 2010, Eni incurred total expenditures amounting to euro 1,151 million for the protection of environment, down 13% from 2009. Current environmental expenses decreased by approximately 13% from 2009, and mainly related to costs incurred with respect to remediation and reclamation activities, carried out mainly in Italy. Capitalized environmental expenditure decreased by 13% and mainly related to soil and subsoil protection, air emissions, energy efficiency and climate change. Eni expects to continue incurring amount of environmental expenditures and expenses in line with or above 2010 levels in future years.

Safety. Safety of our employees and contractors as well as of all people living in the area where activities and assets are located is important to our company. In 2010, there were no significant impacts resulting from new regulations on safety in the workplace. Eni’s business units focused on completing the important organizational changes required by new regulations enacted in 2008.

The improvement and dissemination of safety awareness through all levels of the Company’s organization continued in 2010; this is one of the foundations of Eni’s safety strategy, through a large communication campaign with the target of improving the conduct of workers in the specific field of safety at work. The campaign will be completed this year and will involve 35,000 workers and 25,000 contractors. At the end it will be possible to evaluate the effectiveness of the campaign.

From the end of 2009 and throughout 2010, a number of safety seminars involving the top and middle management of various Business Units have taken place, with the aim of sharing the experiences coming from the implementation of process safety audits in the downstream sector and asset integrity verification tools in the upstream sector. The process safety knowledge improvement effort is continuing with courses targeted at specific areas like functional safety and alarms management.

Results of efforts to achieve a better safety in all activities has brought an improvement of Eni injury frequency rate to 0.91 and of the injury severity rate to 0.03, both decreasing from 2009 and representing the best results ever.

Costs incurred in 2010 to support the safety levels of operations and to comply with applicable rules and regulations were euro 283.5 million, down 45% from 2009. Eni expects to continue incurring amounts of expenses for safety which will be in line with or above 2010 levels in future years.

Health. Eni’s activities for protecting health aim at the continuous improvement of work conditions. Results have been achieved through:

• |  | efficiency and reliability of plants;
• |  | promotion and dissemination of knowledge, adoption of best practices and operating management systems based on advanced criteria of protection of health and internal and external environment;
• |  | certification programs of management systems for production sites and operating units;
• |  | identified indicators in order to monitor exposure to chemical and physical agents;
• |  | strong engagement in health protection for workers operating outside Italy, identifying international health centers capable of guaranteeing a prompt and adequate response to any emergency;
• |  | identification of an effective organization of health centers, in Italy and abroad; and
• |  | training programs for medics and paramedics.

To protect the health and safety of its employees, Eni relies on a network of more than 300 health care centers located in its main operating areas. A set of international agreements with the best local and international health centers ensures efficient services and timely responses to emergencies. The experience acquired in this field, have brought to the elaboration of Health Impact Assessment (HIA) and relative standards to be applied to all new projects of evaluation of working exposure in foreign environment.

In 2010, Eni incurred a total expense of euro 57.8 million, down 28.6% from 2009, to protect the health of its employees. Eni expects to continue incurring amounts of expenses for health which will be in line with or above 2010 levels in future years.

In 2010, Eni total HSE expenses (including cross-cutting issues such as HSE management systems implementation and certification, etc.) amounted to euro 1,578 million, down 18% from 2009.

> Managing GHG emissions and Implementation of the Kyoto Protocol

On February 16, 2005, the Kyoto Protocol entered into force along with commitments provided by Annex I to the Protocol which was ratified by the same parties who joined the Protocol, including the EU and Italy. According to Law No. 120/2002, Italy committed itself to reduce greenhouse gas (GHG) emissions by 6.5% in the period 2008-2012, as compared to GHG levels emitted in 1990. Reductions can be achieved through both internal measures and complementary initiatives.

The latter include the so-called flexible mechanisms, which enables a Party to carry out projects in developing countries (CDM - Clean Development Mechanism) and in industrial countries with transition economies (JI - Joint Implementation) in order to obtain emission credits to fulfill the Kyoto compliance.

Italy is a party to the EU Emission Trading Scheme ("ETS") that was established by Directive No. 2003/87/EC. Effective from January 1, 2005, ETS is the largest virtual market in the world for exchanging emission allowances targeting industrial installations with high carbon dioxide emissions.

As foreseen by the Directive, Italy has issued two National Allocation Plans (NAP) covering the periods 2005-2007 and 2008-2012 which set out the allowances awarded to each sector and installation. The ETS EU directive provides that each member state shall ensure that any operators who produce GHG emissions in excess of the amounts entitled on the base of national allocation plan, will provide allowances to cover excess emissions and also to pay a penalty. The excess emissions penalty amounts to euro 100 (euro 40 for the first period 2005-2007) for each tonne of carbon dioxide equivalent emitted in excess of entitled amounts. All companies are expected to identify and carry out projects for emission reductions.

Eni is part to the ETS. Eni participates in the ETS scheme with 55 plants in Italy and 4 outside Italy, which collectively represent about a third of all greenhouse gas emissions generated by Eni’s plants worldwide. In the period 2005-2007 Eni was entitled to allowances equal to 77.2 mmtonnes of carbon dioxide for existing and new installations. In the period 2008-2012 Eni was entitled to allowances equal to 126.4 mmtonnes of carbon dioxide for existing installations and to further 2.0 mmtonnes in relation to new installations for the 2008-2012 period. Based on the implementation of projects designed to reduce emissions, particularly the start-up of high efficiency combined cycles for the cogeneration of electricity and steam, the amount of carbon dioxide emitted by Eni’s plants has complied with mandatory limits in each of the reported periods up to 2010.

Moreover, Eni monitors the opportunities deriving the Kyoto Flexible Mechanisms. In fact, due to its presence in about 70 Countries, Eni is an elective partner for carrying out CDM and JI projects thus contributing to the Italian

91

##### Table of Contents

program of greenhouse gas emissions reduction. In December 2003, during the Conference of Parties to the Kyoto Protocol – COP9 –, Eni and the Ministry for the Environment signed a Voluntary Agreement for using flexible mechanisms, promoting CDM and JI and contributing to the sustainable development of host countries.

Management believes that the best solutions for complying with the Kyoto Protocol are use of low emission energy sources and adoption of highly efficient technologies. To address the greenhouse gas challenge, Eni performed a detailed analysis for defining its strategy to respond to climate change and to participate in the European emissions trading system, identifying a number of projects for energy saving and emission reductions from its plants.

Management plans to target GHG emissions reduction by implementing certain gas projects designed to exploit associated gas in foreign countries where such gas is flared or released in the atmosphere absent local outlets for that gas. The elimination of flaring and the use of associated gas for the development of local economies enable sustainable development while reducing greenhouse gas emissions. The validation, where possible, of such projects as CDM and JI will provide emission credits and support the Company in achieving its GHG reduction targets in Italy, as set by the Kyoto Protocol. The flaring down project of Kwale Okpai in Nigeria was already registered as a CDM.

More projects are being assessed or implemented in Libya, Congo, Nigeria, Angola and Algeria. Management plans to invest approximately euro 1.1 billion in those projects over the next four years. Moreover, Eni endorsed the Global Gas Flaring Reduction Initiative of the World Bank, in order to move forward completion of gas flaring reduction projects. In the period 2010-2013, a reduction in the trend of Eni total GHG emissions is foreseen due to the planned implementation of the abovementioned projects designed to reduce gas flaring or venting, measures targeting energy efficiency at various Eni’s installations and facilities including refineries, petrochemicals plants and electricity plants, and actions to better manage gas emissions in transport and distribution activities. However, due to new facilities and installations, management believes that Eni’s GHG emissions under the ETS scheme will exceed the entitled allowances in the next four-year period resulting in the incurrence of higher operating expenses in the range of euro 650-750 million. Most of those projected expenses are expected to be incurred in the years 2013-2014, which correspond to the third Phase of Emission Trading. In fact, from 2013, full auctioning will be in force in power sector, while energy-intensive industries exposed to international competition will receive their allowances free of charge as benchmarked to the average performance of the 10% most efficient installations in a specific sector.

To ensure comprehensive, transparent and accurate reporting for GHG emissions, Eni introduced in 2005 its own Protocol for accounting and reporting of greenhouse gas emissions (GHG Accounting and Reporting Protocol), which is an essential requirement for emission certification. Indeed, accurate reporting supports the strategic management of risks and opportunities related to greenhouse gases, the definition of objectives and the assessment of progress. The Eni GHG Protocol has been updated during 2009 to be in compliance with the European and Italian regulation (as the new Monitoring and Reporting Guide Line) and with the best practices reference document (American Petroleum Industry Compendium - August 2009). For safer and more accurate management of GHG emissions and with a view to supporting effective reporting, Eni provided all its business units with a dedicated database, in order to gather and report GHG emissions according to the Protocol and to ensure completeness, accuracy, transparency and consistency of GHG accounting as required by certification needs.

In the medium-term, work is underway on the separation of carbon dioxide and its permanent storage in geologic reservoirs, a part of the CO2 Capture Project, an international R&D program carried out in conjunction with other oil companies. Eni is currently implementing Italy’s first CO2 injection project in Cortemaggiore: its Environmental Impact Assessment procedure is in course of approval by the competent Ministries.

In the long-term, Eni is actively engaged in the political process regarding future emission reduction regulations. Between 2008 and 2009 the feasibility and environmental impact evaluation studies were carried out and completed. Now the project will go under authorization process (VIA). In particular, Eni is involved in bio-energy and bio-fuels.

In both the medium and long-term, management believes that compliance with changes in laws, regulations and obligations relating to climate change could result in substantial capital expenditure, taxes, reduced profitability from changes in operating costs, and revenue generation and strategic growth opportunities being impacted. Eni’s commitment to the transition to a lower-carbon economy may create expectations for our activities and related liabilities, and the level of participation in alternative energies carries reputational, economic and technology risks.

Regulation of Eni’s Businesses

> Overview

The matters regarding the effects of recent or proposed changes in Italian legislation and regulations or EU directives discussed below and elsewhere herein are forward-looking statements and involve risks and uncertainties that could cause the actual results to differ materially from those in such forward-looking statements. Such risks and uncertainties include the precise manner of the interpretation or implementation of such legal and regulatory changes or proposals, which may be affected by political and other developments.

> Regulation of Exploration and Production Activities

Eni’s exploration and production activities are conducted in many countries and are therefore subject to a broad range of legislation and regulations. These cover virtually all aspects of exploration and production activities, including matters such as license acquisition, production rates, royalties, pricing, environmental protection, export, taxes and foreign exchange. The terms and conditions of the leases, licenses and contracts under which these oil and gas interests are held vary from country to country. These leases, licenses and contracts are generally granted by or entered into with a government entity or state company and are sometimes entered into with private property owners. These arrangements usually take the form of licenses or production sharing agreements. See "Regulation of the Italian Hydrocarbons Industry" and "Environmental Matters" in this Item 4 for a description of the specific aspects of the Italian regulation and of environmental regulation concerning Eni’s exploration and production activities.

Licenses (or concessions) give the holder the right to explore for and exploit a commercial discovery. Under a license, the holder bears the risk of exploration, development and production activities and provides the financing for these operations.

In principle, the license holder is entitled to all production minus any royalties that are payable in kind. A license holder is generally required to pay production taxes or royalties, which may be in cash or in kind. Both exploration and production licenses are generally for a specified period of time (except for production licenses in the USA which remain in effect until production ceases). The term of Eni’s licenses and the extent to which these licenses may be renewed vary by area.

In Production Sharing Agreements (PSA), entitlements to production volumes 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 a portion of the production volumes exceeding volumes destined to cover costs incurred (profit oil).

A similar scheme to PSA applies to Service and "Buy-Back" contracts.

In general, Eni is required to pay income tax on income generated from production activities (whether under a license or production sharing agreement). The taxes imposed upon oil and gas production profits and activities may be substantially higher than those imposed on other businesses.

> Regulation of the Italian Hydrocarbons Industry

The matters regarding the effects of recent or proposed changes in Italian legislation and regulations or EU directives discussed below and elsewhere herein are forward-looking statements and involve risks and uncertainties that could cause the actual results to differ materially from those in such forward-looking statements. Such risks and uncertainties include the precise manner of the interpretation or implementation of such legal and regulatory changes or proposals, which may be affected by political and other developments.

> Exploration & Production

The Italian hydrocarbons industry is regulated by a combination of constitutional provisions, statutes, governmental decrees and other regulations that have been enacted and modified from time to time, including legislation enacted to implement EU requirements (collectively, the "Hydrocarbons Laws").

Exploration permits and production concessions. Pursuant to the Hydrocarbons Laws, all hydrocarbons existing in their natural condition in strata in Italy or beneath its territorial waters (including its continental shelf) are the property of the State. Exploration activities require an exploration permit, while production activities require a

93

##### Table of Contents

production concession, in each case granted by the Ministry of Productive Activities through competitive auctions. The initial duration of an exploration permit is six years, with the possibility of obtaining two three-year extensions and an additional one-year extension to complete activities underway. Upon each of the three-year extensions, 25% of the area under exploration must be relinquished to the State. The initial duration of a production concession is 20 years, with the possibility of obtaining a ten-year extension and an additional five-year extension until the field depletes.

Royalties. The Hydrocarbons Laws require the payment of royalties for hydrocarbon production. As per Law No. 99 of July 23, 2009 royalties are equal to 10% and 4%, respectively, for onshore and offshore production of oil and 10% and 7%, respectively, for onshore and offshore production of natural gas.

> Gas & Power

> Natural gas market in Italy

> Legislative Decree No. 130 August 13, 2010 containing measures for increasing competition in the natural gas market and transferring the ensuing benefits to final customers according to Article 30, lines 6 and 7, of Law July 23, 2009, No. 99

In 2010, the regulated period for gas antitrust thresholds defined by Legislative Decree No. 164 of May 23, 2000 expired. Those thresholds defined maximum allowed limits of gas volumes (imported or domestically produced) input into the national transport network and marketed to final customers, applicable to each operator.

Implementing the provisions of Law 99/2009, that system of antitrust thresholds was replaced with a mechanism of market shares enacted by Legislative Decree No. 130 of August 13, 2010 "New measures to improve competitiveness in the natural gas market and to ensure the transfer of economic benefits to final customers" approved by the Italian Council of Ministers. The Decree provides that antitrust ceilings be calculated with reference to the market share of each operator, taking into account the amount of natural gas input into the national network, purchases on spot markets, and sales to importers in Italy made at national network entry points. Consequently, market shares will not be lower than the amount input to the network. Operators in the natural gas market will have to comply with a maximum share of 40% of domestic consumption. A mechanism of gas release at regulated prices is provided in case an operator fails to comply with the mandatory ceilings on the market share. This ceiling can be raised to 55% in case an operator commits to building new storage capacity in Italy for a total of 4 BCM within five years. In this case, the operator is obliged: (i) to allow third parties (such as industrial customers, groups of companies, consortia of final customers and power generation customers) participate in the construction of storage infrastructure either by means of direct investment or long-term contracts for storage services; and (ii) bear the costs associated with giving to third parties 50% of the expected benefits of new capacities under conditions defined by the Ministry for Economic Development and the Authority for Electricity and Gas ("AEEG").

Eni is planning to make the necessary investments to increase storage capacity in Italy so as to benefit from a higher allowed market share.

The Decree introduces measures for increasing competition in the natural gas market aiming at transferring the ensuing benefits to final customers, increasing storage capacity, supporting the security of supplies and enhancing flexibility in the gas system. To achieve this target, compensation to municipalities interested by the construction of new storage fields has been provided.

Eni’s management is monitoring this area and evaluating any possible financial or economic impact associated with the proposed measures and their regulatory evolution. Management also believes that this new gas regulation will increase competition in the wholesale natural gas market in Italy resulting in further margin pressures.

> Law No. 239 of August 23, 2004 on the restructuring of the energy sector in Italy

This law provides for:

• |  | a derogation to third party access granted to companies that make direct or indirect investments for the construction of new infrastructure or the upgrading of existing ones such as: (i) interconnections between EU member states and national networks; (ii) interconnections between non-EU States and national networks for importing natural gas to Italy; (iii) LNG terminals in Italy; and (iv) underground storage facilities in Italy. Investing companies can obtain priority on the assignment of new capacity for a portion of not less than 80% of the new capacity installed and for a period of at least 20 years; and
• |  | paragraph 69 provides interpretation of the rule introduced by Legislative Decree No. 164/2000 concerning the transitional regime of concessions for natural gas distribution activities in urban centers existing at June 21, 2000, which allows for an anticipated repayment of the distribution service, despite

94

##### Table of Contents

|  | being provided through a bid procedure rather than direct entitlements. This law changes the provisions defined by Legislative Decree No. 164/2000 by: (i) extending to December 31, 2007, the transitional period for the continuation of existing concessions, with a possible extension of one further year when public interest is considered important by local authorities; and (ii) canceling the adding up of possible extensions, as provided for by Legislative Decree No. 164/2000, in case of certain conditions (business restructuring, size parameters, shareholding composition). The end of concessions awarded on the basis of a bid procedure remains set as of December 31, 2012. Currently, the Ministry for Economic Development is drafting a revision of the distribution gas market with the aim of reducing the number of distribution companies by providing for an extension of the territory reach of each concession.

> Law No. 290/2003

Law No. 290/2003 prohibits companies operating in the natural gas and power industries to hold stakes higher than 20% in the share capital of companies owning and managing national networks for the transmission of natural gas and power. The term by which companies must comply with this provision, which was initially fixed as of December 31, 2008, has been rescheduled in a 24-month period deadline following enactment of a specific decree from the Italian Prime Minister which is to establish terms and conditions of the divestments. Currently, Eni is unable to predict any evolution of this matter.

In addition, on March 23, 2006 a Presidential Decree defined criteria and methods for the divestment of the interest held by Eni in Snam Rete Gas SpA, introducing the special powers of the Ministry of Economy and Finance provided for by the regulations on the divestment of interests held by the Italian Government ("golden share") in the By-laws of Eni. Management believes that this decree may impact Eni in case the Company makes plans to divest the whole or a portion of its interest in Snam Rete Gas. Eni’s interest in Snam Rete Gas will also be affected by the due steps that Italian institutions have been implementing to enact Directive No. 2009/73/EC in Italian laws. See below.

> Regulations aimed at increasing competition in the Italian wholesale segment of natural gas

In order to implement measures defined by the Italian Government to face the economic downturn, a number of administrative provisions relating to the so-called gas release measures have been enacted in an effort by Italian administrative Authorities to boost the level of competition and liquidity of the Italian gas market. Those measures have strongly affected Eni’s marketing activity in Italy. Legislative Decree No. 78/2009 obliged Eni to make a gas release at the virtual exchange point for a total of 5 BCM of gas in yearly and half-yearly amounts. Although the allotment procedure (bid) was based on a minimum price set by the Ministry for Economic Development as proposed by the AEEG (Eni considering this point discriminatory, filed a claim with the competent authority), only a 1.1 BCM portion of the gas release was awarded out of the 5 BCM which had been planned. For the next few years, also based on indications of the Authority for Electricity and Gas, Eni believes that it is possible that the Company will be forced to implement additional gas release measures.

> Negotiation Platform for gas trading

In compliance with the provisions of Law No. 99 of July 23, 2009, on March 18, 2010, the Ministry for Economic Development published a Decree that implements a trading platform for natural gas starting from May 10, 2010 aimed at increasing competition and flexibility on wholesale markets. Management and organization of this platform are entrusted to an independent operator, the GME (Gestore del Mercato Elettrico). On this platform are traded volumes of gas corresponding to the legal obligations on part of Italian importers and producers as per Law Decree No. 7/2007. Under these provisions, importers from non-European countries were expected to supply given amounts of gas (from 5% to 10% of total gas import) to the virtual exchange in order to receive permission to import, as well as volumes corresponding to royalties due by owners of mineral rights to the Italian state (and to Basilicata and Calabria Regions). Eni was required to offer at that platform about 200 mmCM related to the residual obligation for volumes imported in thermal year October 1, 2008-September 30, 2009, and to the offer obligation for the October 1, 2009-September 30, 2010 thermal year, as well as approximately 215 mmCM related to royalties due for 2009 full year. Operators, also non-importers, are allowed to negotiate additional gas volumes over the compulsory amounts on the platform according to the supply rules determined by the AEEG. Since December 2010, the GME is also trader’s counterparty in transactions on the spot market for natural gas (divided into day-ahead market and intraday market).

##### Table of Contents

> Natural gas prices

Following the liberalization of the natural gas sector introduced in 2000 by Decree No. 164, prices of natural gas sold to industrial and power generation customers as well as to wholesalers are freely negotiated. However the AEEG holds a power of surveillance on this matter (see below) under Law No. 481/1995 (establishing the AEEG) and Legislative Decree No. 164/2000.

Furthermore, the AEEG is entrusted by the Presidential Decree dated October 31, 2002 with the power of regulating natural gas prices to residential and commercial customers which were not eligible until December 31, 2002, also after the full opening up of the gas market from January 1, 2003, additionally targeting the public goal of containing inflationary pressure deriving from increasing energy costs. Consistently with this decree, at present on the basis of different resolutions of the AEEG companies selling natural gas through local networks have to offer to residential customers and customers who live in buildings consuming, on the whole, less than 200,000 CM/y the regulated tariffs beside their own price proposals.

> Change in the criteria for determining and upgrading tariffs applied to residential customers: Resolution ARG/gas 89/2010

On June 18, 2010, the AEEG published a resolution ARG/gas 89/2010, applied to the October 1, 2010-September 30, 2011 thermal year, providing for a 7.5% reduction in the raw material cost component of those supplies in determining tariffs for residential users consuming less than 200,000 CM/y. Considering that the new calculation does not cover the supply costs of an efficient portfolio of long-term contracts and considering the relevant impact on its consolidated accounts deriving from this new resolution, Eni’s management has appealed against the ARG/gas 89/2010 resolution. This appeal is part of an ongoing administrative litigation which follows the partial annulment of AEEG Resolution No. 79/2007, pronounced by the Administrative Court of Lombardy in November 2010, with reference to the mechanism of indexation of the cost of raw material supplies to residential customers.

> Directive No. 2009/73/EC of the European Parliament and Council on common regulations for the internal natural gas market

On July 13, 2009, European Directive No. 2009/73/EC on the regulation of the internal natural gas market was issued. Member states are expected to implement it in their legislation by March 3, 2011, and to choose one of two options for guaranteeing the independence of transport companies.

The two options provided are:

(i) |  | Separation of ownership under two alternative modes:
|  | - | Ownership Unbundling (OU): the company that owns the networks and manages transport activities is unbundled from its integrated parent company that will retain supply/production and sale activities; and
|  | - | Independent System Operator (ISO): the vertically integrated company retains ownership of the networks but confers their management to a third independent party.
(ii) |  | Strengthened functional separation:
|  | - | Independent Transmission Operator (ITO): the vertically integrated company retains control of the company that manages transport activities and owns transport networks, provided the vertically integrated company refrains from interfering in the decision making process of the controlled carrier company.

On March 3, 2010, the Italian Council of Ministers presented a draft legislative decree to implement Directive No. 2009/73/EC. Among the possible options, the decree provides for the adoption of the ITO model by Snam Rete Gas by March 3, 2012.

> Fully-Regulated Businesses in the Italian Gas Market

> Transport

Transport tariffs. The AEEG set transport criteria companies have to apply in determining natural gas transport and dispatching tariffs on national and regional transport networks, for each regulatory period made up of four years, as provided for by Decree No. 164/2000. Tariffs are subject to approval by the Authority, which ensures their compliance with preset criteria.

96

##### Table of Contents

Criteria established by the AEEG set allowed revenues that are calculated as the sum of: (i) operating costs including storage and modulation costs; (ii) amortization and depreciation of transport assets; and (iii) return on net capital employed.

With Resolution ARG/gas 184/2009, published on December 2, 2009, the Authority set the criteria regulating the tariffs for natural gas transport on the national and regional gas pipeline network for the third regulatory period (January 1, 2010-December 31, 2013).

The Regulated Asset Base (RAB) is calculated with the re-valuated historical cost methodology.

The allowed pre-tax rate of return (WACC) on the Regulatory Asset Base (RAB) has been set equal to 6.4% in real terms.

The new tariff structure confirms recognition in tariff of expenditures incurred for network upgrading, providing for a higher remuneration than WACC, in a measure ranging from one to three percentage points of additional remuneration in relation to the nature of expenditures and for a period of 5 to 15 years.

Depreciation charges of gas transport infrastructures (gas pipelines) are determined on a 50-year useful technical life and are excluded from the price cap mechanism. Operating costs are defined with reference to operating costs incurred during 2008 and increased by a 50% rate to factor in productivity gains achieved in the second regulatory period. Fuel gas is excluded from the price cap mechanism.

The revenue component related to volumes transported is determined on the basis of operating costs recognized in tariff and amounts to approximately 15% of revenue cap.

With Resolution ARG/gas 218/2010, the AEEG also recognized to Snam Rete Gas a total amount of euro 54.9 million as settlement of additional costs incurred from October 1, 2008 to December 31, 2009 relating to the purchase of fuel gas for compression stations.

Network Code. From 2003, Snam Rete Gas Network Code is in force, regulating entitlements of transport capacity, obligations on part of both the transporter and the customer and the procedures through which customers can resell capacity to other users. Transport capacity at entry points to the national gas pipeline network (point of interconnection with import gas lines) is entitled on an annual basis with duration of up to five thermal years. Capacity products with duration shorter than one year are also available.

The Network Code, approved by the AEEG with Resolution No. 75 of July 1, 2003, is based on the criteria set by the same Regulator with Resolution No. 137/2002. This resolution sets priority criteria for transport capacity entitlements at points where the Italian transport network connects with international import pipelines (the so-called entry points to the Italian transport system). Specifically, operators that are party to take-or-pay purchase contracts, as in the case of Eni, are entitled to a priority in allocating available transport capacity within the limit of average daily contractual volumes. Gas volumes exceeding average daily contractual volumes are not entitled to any priority and, in case of congestion at any entry points, they are entitled available capacity on a proportionate basis together with all pending requests for capacity entitlements. The ability of Eni to collect gas volumes exceeding average daily volumes as provided by its take-or-pay purchase contracts represents an important operational flexibility that the Company uses to satisfy demand peaks. In planning its commercial flows, the Company normally assumes to fully utilize its contractual flexibility and to obtain the necessary capacity entitlements at the entry points to the national transport network. Eni believes that Resolution No. 137/2002 is in contrast with the rationale of the European regulatory framework on the gas market as provided in Directive No. 2003/55/EC. Based on that belief, the Company has opened an administrative procedure to repeal it before an administrative court which has recently confirmed in part Eni’s position. An upper grade court also confirmed the Company’s position. Specifically, the Administrative Court stated that the purchase of contractual flexibility is an obligation on part of the importer, which responds to a collective interest. According to the Administrative Court, there is no reasonable motivation whereby volumes corresponding to such contractual flexibility should not be granted priority in the access to the network, also in case congestion occurs. At the moment, however, no case of congestion occurred at entry points to the Italian transport infrastructure so as to impair Eni’s marketing plans.

> Re-gasification

Re-gasification tariffs. The AEEG has set the criteria regulating the tariffs for the use of LNG terminals in the 3rd regulatory period (October 2008-September 2012) with its Resolution ARG/gas 92/2008.

The Regulatory Asset Base (RAB) is calculated with the re-valuated historical cost methodology. The yearly adjustment of revenues and tariffs will follow the same methodologies applied in the previous regulatory period,

97

##### Table of Contents

except for depreciation that will be adjusted on a yearly basis and excluded from the price cap mechanism. The allowed rate of return (WACC) on Regulatory Asset Base has been set equal to 7.6% in real terms pre tax.

Furthermore, it established an additional remuneration, up to 3% above WACC, for new capital expenditures for a maximum of 16 years.

Operating costs will be adjusted every year taking into account inflation and efficiency gains (X-factor) set by the Authority at 0.5% in real terms.

Resolution ARG/gas 92/2008 also established that the allocation of reference revenues between re-gasification capacity and the commodity component is fixed at 90:10 (compared to 80:20 ratio in the second regulated period).

Re-gasification Code. From 2007 GNL Italia Re-gasification Code is in force, defining rules and regulations for the operation and management of the re-gasification plant of Panigaglia in North-West Italy. The Code, approved with the Resolution VIS 8/2009, is based on the criteria for access to LNG re-gasification services set by the same Regulator with Resolution No. 167/2005 (August 1, 2005) in accordance with Legislative Decree No. 164/2000. The decision also defines criteria for the allocation of re-gasification capacity. In particular it establishes that take-or-pay contracts entered into before 1998, as in the case of Eni, are awarded priority access limited to the minimum amount of volumes that have been re-gasified in the period starting from thermal year 2001-2002. Eni filed a claim against this decision with the Regional Administrative Court of Lombardy that rejected the claim. Subsequently, Eni filed a claim with a higher degree administrative court.

Distribution is the activity of delivering natural gas to residential and commercial customers in urban centers through low pressure networks. Distribution is considered a public service operated in concession and is regulated on the basis of Law Decree No. 164/2000.

Distribution tariffs. With Resolution No. 159/2008, the AEEG defined a new methodology for determining revenues for natural gas distribution activity. Starting from January 1, 2009 and for the duration of a four-year regulated period, i.e. until 2012, the resolution provides for the recognition of total revenues for each regulated year amounting to a value that the Authority will set at the time of approving the operators’ requests for distribution tariffs and defined as Total Revenue Constraint (TRC), representing the maximum remuneration recognized by the AEEG to each operator for covering costs borne.

In previous years, revenues were determined by applying tariffs set by the AEEG to volumes actually distributed to selling companies in the relevant year. The resolution also provides for any positive or negative difference between TRC and revenues resulting from invoices for actually distributed volumes to be regulated through an equalization device making use of credit/debit cards lodged with the Electricity Equalization Exchange.

As a result of the new mechanism, revenues are no longer related to the seasonality of volumes distributed but are constantly apportioned during the year. The introduction of this new mechanism does not cause a decline in total revenues on a yearly basis.

> Storage of natural gas

Storage activities in Italy are regulated by Decree No. 164/2000. The most important aspects of Decree No. 164 concerning storage activities are the following: (i) in vertically integrated enterprises, storage is to be carried out by a separate company not operating in other gas activities (such as Eni’s subsidiary Stoccaggi Gas Italia SpA) or by companies engaged only in transport and dispatching activities, provided the accounts of these two activities are clearly separated from the accounts of storage; (ii) storage activity is exercised pursuant to concessions granted by the Ministry of Productive Activities. The duration of a concession is 20 years, with the possibility of obtaining at most two ten-year extensions if operators complied with the storage programs and other obligations deriving from applicable laws. Existing storage concessions are subject to the decree. Their original term was confirmed and includes relevant production concessions; (iii) the need for strategic storage in Italy is defined explicitly; the burden of strategic storage is imposed upon companies importing from non-EU countries, which have to provide a strategic storage capacity in Italy corresponding to 10% of the amount of natural gas imported each year; (iv) holders of storage concessions are required to provide storage capacity for domestic production, for strategic use and for modulation to eligible users without discriminations, where technically and economically viable; (v) modulation storage costs are charged to shippers which have to provide modulation services adequate to the requirements of their final customers; (vi) storage tariffs criteria are determined by the AEEG in order to ensure a preset return on capital employed, taking into account the typical risk inherent in this activity, as well as volumes stored for ensuring

peak supplies and the need to incentive capital expenditure for upgrading the storage system; and (vii) the AEEG establishes the criteria and priority of access storage operators have to include in their own storage codes.

In compliance with the provisions of Article 21 of Decree No. 164/2000, on October 21, 2001 all storage activities carried out within the Eni Group were conferred to Stoccaggi Gas Italia SpA ("Stogit"), which holds ten storage concessions.

Storage tariffs. On August 3, 2010, the AEEG with Resolution No. 119/2010 published the criteria for determining storage tariffs for the 2011-2014 regulated period.

According to this resolution, 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 6.7% (7.1% in the second regulated period);
(ii) |  | depreciation and amortization charges;
(iii) |  | dismantling costs; and
(iv) |  | 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.

Applicable regulation provides for incentives to capital expenditures 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.

Storage Code. From November 1, 2006 Stoccaggi Gas Italia (Stogit) Storage Code is in force.

This Code regulates access to and provision of storage services during normal operational conditions, regulates procedures for conferring storage capacities, fees to be charged to customers in case they uplift from or input to storage sites volumes in excess or uses higher input/uplift capacity with respect to scheduled and operating programs. On the basis of these provisions, Eni may incur significant charges for storage services should the Company fail to use storage services in accordance with scheduled operating programs.

The storage company offers services according to the access priority established by the AEEG as follows: (i) mandatory services, including modulation storage, mineral storage, and strategic storage services; and (ii) services for operating needs of transport companies, including hourly modulation.

The modulation storage service is geared towards satisfying modulation needs of natural gas users in terms of peak consumption and daily or seasonal trends in consumption. 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 off-take on an annual basis in accordance with its storage code.

The mineral storage service aims to allow natural gas producers to perform their activity under optimal operating conditions, according to criteria determined by the Ministry for Economic Development.

The strategic storage service aims to satisfy certain obligations of natural gas importers from countries not belonging to the EU in accordance with Article 3 of Legislative Decree No. 164/2000. The relevant storage capacity dedicated to this service is determined by the Ministry for Economic Development.

Storage capacity is awarded by the storage company for periods no longer than a thermal year by April 1, of each year. The first requests to be met are those for strategic storage and for the operating balancing of the system.

The residual capacity available and the maximum daily uplift capacity is awarded according to the following order of priority to: (i) holders of production concessions requesting mineral storage services; (ii) natural gas selling operators who are held to provide a modulation service of their supply to their customers according to Article 18, paragraphs 2 and 3 of Legislative Decree No. 164/2000, for maximum volumes corresponding to a seasonal demand peak with average temperatures, on the terms and conditions established by a procedure to be issued by the Regulatory Authority for Electricity and Gas; (iii) to the entities mentioned in (ii) above only for those additional maximum volumes related to a seasonal demand peak in case of certain low temperatures measured on a 20-year period, under the terms and conditions of the procedure mentioned in (ii) above; and (iv) the entities requesting access for services different from the ones mentioned above.

##### Table of Contents

From November 2009, according to the Resolution No. 165/2009 set by the Regulator, monthly based storage services are available for gas-network users (Shippers). Storage capacities are sold on auction basis.

Eni held natural gas for strategic reserve purposes in its storage business, as established by Decree No. 164/2000.

The strategic reserves of gas are defined as "stock destined to meet situations of deficit/decrease of supply or crisis of the gas system". The Ministry for Economic Development determines quantities and usage criteria of such reserves. As of December 31, 2010, Eni held approximately 177 BCF of strategic reserves of natural gas (177 BCF at year end 2009).

> Refining and Marketing of Petroleum Products

Refining. Under Legislative Decree No. 112 of March 31, 1998, companies that seek to establish refining operations in Italy or to expand the capacity of existing refining operations must obtain an operating concession from the relevant region, while companies that seek to build or operate new plants that do not increase refining capacity must obtain an authorization from the relevant region. Management expects no material delays in obtaining relevant concessions for the upgrading of the Sannazzaro and Taranto refineries as planned in the medium-term.

Service stations. Legislative Decree No. 32 of February 11, 1998, as amended by Legislative Decree No. 346 of September 8, 1999 and Law Decree No. 383 of October 29, 1999, as converted in Law No. 496 of December 28, 1999, significantly changed Italian regulation of service stations. Legislative Decree No. 32 replaces the system of concessions granted by the Ministry of Industry, regional and local authorities with an authorization granted by city authorities while the Decree No. 112 still confirms the system of such concessions for the construction and operation of service stations on highways and confers the power to grant to Regions. Decree No. 32 also requires that contracts between license holders and service station operators have a duration of not less than six years and are drafted in accordance with arrangements agreed by the relevant trade group of license holders and the union representatives for the service station operators. Decree No. 32 also provides for: (i) the testing of compatibility of existing service stations with local planning and environmental regulations and with those concerning traffic safety to be performed by city authorities; (ii) upon the closure of at least 7,000 service stations, the option to extend by 50% the opening hours (currently 52 hours per week) and a generally increased flexibility in scheduling opening hours; (iii) simplification of regulations concerning the sale of non-oil products and the permission to perform simple maintenance and repair operations at service stations; and (iv) the opening up of the logistics segment by permitting third party access to unused storage capacity for petroleum products. With the same goal of renewing the Italian distribution network, Law No. 57 of March 5, 2001 provides that the Ministry of Productive Activities is to prepare guidelines for the modernization of the network, and the Regions shall follow those guidelines in the preparation of regional plans. The subsequent Ministerial Decree of October 31, 2001 establishes the criteria for the closing down of incompatible stations, the approval of the plan, the renewal of the network, the opening up of new stations and the regulations of the operations of service stations on matters such as automation, working hours and non-oil activities.

Law No. 133 of August 6, 2008, by intervening in competition provisions, removes some national and regional regulations which might prejudice the liberty of establishment and introduces new provisions particularly concerning the elimination of restrictions concerning distances between service stations, the obligation to undertake non-oil activities and the liberalization of opening hours. Management believes that those measures will favor competition in the Italian retail market and support efficient operators.

Petroleum product prices. Petroleum product prices were completely deregulated in May 1994 and are now freely established by operators. Oil and gas companies periodically report their recommended prices to the Ministry of Productive Activities; such recommendations are considered by service station operators in establishing retail prices for petroleum products.

Compulsory stocks. According to Legislative Decree of January 31, 2001, No. 22 ("Decree 22/2001") enacting Directive No. 1993/98/EC (which regulates the obligation of member states to keep a minimum amount of stocks of crude oil and/or petroleum products) compulsory stocks, must be at least equal to the quantities required by 90 days of consumption of the Italian market (net of oil products obtained by domestically produced oil). In order to satisfy the agreement with the International Energy Agency (Law No. 883/1977), Decree 22/2001 increased the level of compulsory stocks to reach at least 90 days of net import, including a 10% deduction for minimum operational requirements. Decree 22/2001 states that compulsory stocks are determined each year by a decree of the Minister for Economic Development based on domestic consumption data of the previous year, defining also the amounts to be held by each oil company on a site-by-site basis.

Law No. 96 of June 4, 2010 requires the government to follow some principles and criteria in drafting the legislative decree that shall implement, by December 31, 2012, Directive No. 2009/119/EC (imposing an obligation

on member states to maintain minimum stocks of crude oil and/or petroleum products), in particular: (a) keep a high level of oil security of supply through a reliable mechanism to assure the physical access to oil emergency and specific stocks; and (b) provide for the institution of a Central Stockholding Entity under the control of the Ministry for Economic Development – with the mandatory participation of entities who have imported oil or petroleum products – that should be in charge of: (i) the holding and transport of specific stocks of products, (ii) the stocktaking, (iii) the statistics on emergency, specific and commercial stocks; and, eventually, (iv) the provision of a storage and transportation service of emergency and commercial stocks in favour of sellers of petroleum products to final clients not vertically integrated in the oil chain.

As of December 31, 2010, Eni owned 6.5 mmtonnes of oil products inventories, of which 4.2 mmtonnes as "compulsory stocks", 1.7 mmtonnes related to operating inventories in refineries and depots (including 0.2 mmtonnes of oil products contained in facilities and pipelines) and 0.4 mmtonnes related to specialty products.

Eni’s compulsory stocks (as of December 31, 2010) were held in term of crude oil (33%), light and medium distillates (46%), fuel oil (16%) and other products (5%) and they were located throughout the Italian territory both in refineries (78%) and in storage sites (22%).

> Competition

Like all Italian companies, Eni is subject to Italian and EU competition rules. EU competition rules are set forth in Articles 101 and 102 of the Lisbon Treaty on the Functioning of the European Union entered into force on December 1, 2009 ("Article 101" and "Article 102", respectively being the result of the new denomination of former Articles 81 and 82 of the Treaty of Rome as amended by the Treaty of Amsterdam dated October 2, 1997 and entered into force on May 1, 1999) and EU Merger Control Regulation No. 139 of 2004 ("EU Regulation 139"). Article 101 prohibits collusion among competitors that may affect trade among member states and that has the object or effect of restricting competition within the EU. Article 102 prohibits any abuse of a dominant position within a substantial part of the EU that may affect trade among member states. EU Regulation 139 sets certain turnover limits for cross-border transactions, above which enforcement authority rests with the European Commission and below which enforcement is carried out by national competition authorities, such as the Antitrust Authority in the case of Italy. On May 1, 2004, a new regulation of the European Council came into force (No. 1/2003) which substitutes Regulation No. 17/1962 on the implementation of the rules on competition laid down in Articles 101 and 102 of the Treaty. In order to simplify the procedures required of undertakings in case of conducts that potentially fall within the scope of Article 101 and 102 of the Treaty, the new regulation substitutes the obligation to inform the Commission with a self assessment by the undertakings that such conducts does not infringe the Treaty. In addition, the burden of proving an infringement of Article 101(1) or of Article 102 of the Treaty shall rest on the party or the authority alleging the infringement. The undertaking or association of undertakings claiming the benefit of Article 101(3) of the Treaty shall bear the burden of proving that the conditions of that paragraph are fulfilled. The regulation defines the functions of Authorities guaranteeing competition in member states and the powers of the Commission and of national courts. The competition authorities of the member states shall have the power to apply Articles 101 and 102 of the Treaty in individual cases. For this purpose, acting on their own initiative or on a complaint, they may take the following decisions:

• |  | requiring that an infringement be brought to an end;
• |  | ordering interim measures;
• |  | accepting commitments; and
• |  | imposing fines, periodic penalty payments or any other penalty provided for in their national law.

National courts shall have the power to apply Articles 101 and 102 of the Treaty. Where the Commission, acting on a complaint or on its own initiative, finds that there is an infringement of Article 101 or of Article 102 of the Treaty, it may: (i) require the undertakings and associations of undertakings concerned to bring such infringement to an end; (ii) order interim measures; (iii) make commitments offered by undertakings to meet the concerns expressed to them by the Commission binding on the undertakings; and (iv) find that Articles 101 and 102 of the Treaty are not applicable to an agreement for reasons of Community public interest.

Eni is also subject to the competition rules established by the Agreement on the European Economic Area (the "EEA Agreement"), which are analogous to the competition rules of the Lisbon Treaty (ex Treaty of Rome) and apply to competition in the European Economic Area (which consists of the EU and Norway, Iceland and Liechtenstein). These competition rules are enforced by the European Commission and the European Free Trade Area Surveillance Authority.

In addition, Eni’s activities are subject to Law No. 287 of October 10, 1990 (the "Italian Antitrust Law"). In accordance with the EU competition rules, the Italian Antitrust Law prohibits collusion among competitors that restricts competition within Italy and prohibits any abuse of a dominant position within the Italian market or a significant part thereof. However, the Italian Antitrust Authority may exempt for a limited period agreements among companies that otherwise would be prohibited by the Italian Antitrust Law if such agreements have the effect of improving market conditions and ultimately result in a benefit for consumers.

Property, Plant and Equipment

Eni has freehold and leasehold interests in real estate in numerous countries throughout the world. Management believes that certain individual petroleum properties are of major significance to Eni as a whole. Management regards an individual petroleum property as material to the Group in case it contains 10 per cent or more of the Company’ worldwide proved oil and gas reserves and management is committed to invest material amounts of expenditures in developing it in the future. See "Exploration & Production" above for a description of Eni’s both material and other properties and reserves and sources of crude oil and natural gas.

Organizational Structure

Eni SpA is the parent company of the Eni Group. As of December 31, 2010, there were 270 fully-consolidated subsidiaries and 76 associates that were accounted for under the equity or cost method. For a list of subsidiaries of the Company, see "Exhibit 8. List of Eni’s fully-consolidated subsidiaries for year 2010".

Item 4A. UNRESOLVED STAFF COMMENTS

Item 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

This section is the Company’s analysis of its financial performance and of significant trends that may affect its future performance. It should be read in conjunction with the Key Information presented in Item 3 and the Consolidated Financial Statements and related Notes thereto included in Item 18. The Consolidated Financial Statements are prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the IASB.

This section contains forward-looking statements which are subject to risks and uncertainties. For a list of important factors that could cause actual results to differ materially from those expressed in the forward-looking statements, see the cautionary statement concerning forward-looking statements on page ii and "Item 3 – Risk Factors".

Executive Summary

Eni reported net profit of euro 6,318 million for the year ended December 31, 2010, representing an increase of 44.7% from 2009. That amount represented net profit attributable to Eni’s shareholders.

The Group operating profit for the year ended December 31, 2010 amounted to euro 16,111 million, up 33.6% from 2009 mainly related to: (i) a positive operating performance reported by the Exploration & Production segment, reflecting higher oil realizations in U.S. dollar terms (up 27.8%), and the depreciation of the euro against the U.S. dollar (down 4.7%); (ii) higher results of the Engineering & Construction Division which were driven by revenue growth and increased profitability of acquired orders; and (iii) improved operating results recorded by both the downstream refining and petrochemical businesses thanks to a more favorable trading environment. In contrast, the Gas & Power Division reported sharply lower results due to lower unit margins on sales outside Italy and volumes losses in the Italian market reflecting increased competitive pressures and oversupply conditions in the gas market. Results of the Gas & Power Division were also hit by an impairment charge amounting to euro 426 million relating to goodwill due to a reduced profitability outlook for the European gas marketing business.

Operating profit benefited from the recognition of an inventory holding gain amounting to euro 881 million (euro 345 million in 2009), reflecting the impact of rising prices of crude oil and products on year end valuation of inventories according to the average cost method of inventory accounting. Those gains were partly offset by higher environmental provisions as the Company recorded a charge amounting to euro 1,109 million to account for a proposal of a global environmental settlement with the Italian Ministry for the Environment. The proposed settlement is intended to define the Company’s commitments to perform clean-up and remediation activities at certain Italian sites and settle all pending civil and administrative litigation on the issue of environmental damage. See "Significant Transactions" below for a full description of the proposed transactions.

##### Table of Contents

Group results for the year also benefited from higher profits reported by non-consolidated entities that are accounted for under the equity or the cost method (up euro 587 million).

Net cash provided by operating activities amounted to euro 14,694 million for the year ended December 31, 2010 and benefited from a cash inflow from transferring certain account receivables without recourse to factoring institutions, amounting to euro 1,279 million due in 2011. These inflows were balanced by outflows for pre-payments to the Company’s suppliers of gas under long-term contracts upon triggering the take-or-pay clause (euro 1,238 million). Net cash provided by operating activities, together with cash proceeds from divestments amounting to euro 1,113 million, were used to fund part of the cash outflows relating to capital expenditures totaling euro 13,870 million and dividend payments to Eni’s shareholders amounting to euro 3,622 million. Dividends paid to non-controlling interests amounted to euro 514 million, mainly relating to Saipem and Snam Rete Gas.

As of December 31, 2010 net borrowings amounted to euro 26,119 million, an increase of euro 3,064 million from December 31, 2009.

In 2010, oil and natural gas production available for sale averaged 1,757 KBOE/d. Production for the year expressed in barrel-of-oil equivalent was computed assuming a natural gas conversion factor which was updated to 5,550 cubic feet of gas equals 1 barrel of oil. See disclosure in a footnote to the "Conversion Table" on page vi. On a comparable basis, i.e. when excluding the effect of updating the gas conversion factor, production showed an increase of 0.9% for the full year. Production growth was driven by additions from new field start-ups, particularly the Zubair field (Eni’s interest 32.8%) in Iraq (for a total increase of 40 KBOE/d). These increases were offset in part by mature field declines.

Worldwide gas sales in 2010 amounted to 97.06 BCM, down 6.4% from 2009 due to lower volumes supplied to the Italian market (down 5.75 BCM, or 14.4%) against the backdrop of stronger competitive pressures and oversupply on the marketplace which also hit sales to importers of natural gas in Italy (down 2.04 BCM or 19.5%). These declines were partly offset by higher volumes achieved in a number of European markets driven by growth in France, Northern Europe (including the UK), Germany/Austria and the Iberian Peninsula, while sales decreased in Turkey, Belgium and Hungary.

In 2010, capital expenditures amounted to euro 13,870 million (euro 13,695 million in 2009) and related mainly to:

• |  | oil and gas development activities (euro 8,578 million) deployed mainly in Egypt, Kazakhstan, Congo, the USA and Algeria;
• |  | exploration projects (euro 1,012 million), of which 97% carried out outside Italy, primarily in Angola, Nigeria, in the USA, Indonesia and Norway;
• |  | upgrading of the fleet used in the Engineering & Construction Division (euro 1,552 million);
• |  | development and upgrading of Eni’s natural gas transport network in Italy (euro 842 million) and distribution network (euro 328 million), as well as development and increasing storage capacity (euro 250 million); and
• |  | projects aimed at improving the conversion capacity and flexibility of refineries (euro 446 million), as well as building and upgrading service stations in Italy and outside Italy (euro 246 million).

During the 2010-2014 four-year period, Eni expects to invest approximately euro 53.3 billion in capital expenditures and exploration projects to implement its growth strategy, based on the assumptions discussed below under "Management’s Expectation of Operations".

##### Table of Contents

When the term margin is used in the following discussion, it refers to the difference between the average selling price and direct acquisition cost of a finished product or raw material excluding other production costs (e.g. refining margin, margin on distribution of natural gas and petroleum products or margin of petrochemicals products). Margin trends reflect the trading environment and are, to a certain extent, a gauge of industry profitability.

Eni’s results of 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, thus affecting results of operations of the natural gas business and, to a lesser extent, of the refining and marketing business. See "Item 3 – Risk Factors".

In 2010, Eni’s results were driven by higher oil realizations driven by rising Brent prices which were up 29.2% from 2009. Results also benefited from the depreciation of the euro versus the U.S. dollar, down by 4.7%, which improved the operating results reported by Eni’s subsidiaries whose functional currency is the U.S. dollar. Unit margins in the marketing of gas outside Italy were hit by lower price differentials between spot prices for gas recorded in European continental hubs, as those prices have become the benchmark in contractual selling formulae in Europe, and the Company’s purchase costs of gas which have remained mainly indexed to the cost of oil and certain refined products. Eni’s realized refining margins in U.S. dollar terms remained at unprofitable levels as the Brent benchmark refining margin for the year was down 0.47 $/BBL, or 15% from 2009. That trend reflected higher oil-feedstock costs which were only partially transferred to prices of refined products at the pump pressured by weak underlying fundamentals (slow demand, excess capacity, high inventory levels). Nonetheless, Eni’s realized margins posted a slight improvement from the depressed levels of the year-earlier due to wider price differential between sour and sweet crude qualities and higher relative prices of middle distillates compared to heating oil, which benefited Eni’s complex refineries. Petrochemical product margins also improved from the prior year as high oil-based feedstock costs were at least partially offset by higher chemicals commodity prices on the back of a recovery in demand.

Critical Accounting Estimates

The Company’s Consolidated Financial Statements are prepared in accordance with IFRS as issued by IASB. These require the use of estimates and assumptions that affect the assets, liabilities, revenues and expenses reported in the financial statements, as well as amounts included in the notes thereto, including discussion and disclosure of contingent liabilities. Estimates made are based on complex or subjective judgments and past experience of other assumptions deemed reasonable in consideration of the information available at the time. The accounting policies and areas that require the most significant judgments and estimates to be used in the preparation of the Consolidated

104

##### Table of Contents

Financial Statements are in relation to the accounting for oil and natural gas activities, specifically in the determination of proved and proved developed reserves, impairment of fixed assets, intangible assets and goodwill, asset retirement obligations, business combinations, pensions and other post-retirement benefits, recognition of environmental liabilities and recognition of revenues in the oil field services construction and engineering businesses. Although the Company uses its best estimates and judgments, actual results could differ from the estimates and assumptions used. A summary of significant estimates follows.

> 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 that can be economically producible with reasonable certainty from known reservoirs under existing economic conditions and operating methods. 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, 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 classified as proved undeveloped. Volumes will subsequently be reclassified 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. Eni reassesses its estimate of proved reserves periodically. The estimated proved reserves of oil and natural gas may be subject to future revision and upward and downward revision may be made to the initial booking of 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 in regards to 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 Consolidated 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 for each field decreases depreciation, depletion and amortization expense. Conversely, 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 or not property impairment is to be carried out. The larger the volume of estimated reserves, the lower the likelihood of asset impairment.

> Impairment of assets

Eni assesses its tangible assets and intangible assets, including goodwill, for possible impairment if there are events or changes in circumstances that indicate 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, a reduced utilization of the plants and, for oil and gas properties, significant downward revisions of estimated proved reserve quantities or significant increase of the estimated development costs. 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. Similar remarks are valid for the physical recoverability of assets recognized in the balance sheet (deferred cost – see "Item 18 – Note 20 to the Consolidated Financial Statements") related to natural gas volumes not collected under long-term purchase contracts with take-or-pay clauses.

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 cost or the 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 analyses 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.

##### Table of Contents

For oil and natural gas properties, the expected future cash flows are estimated principally 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. Oil, natural gas and petroleum product prices (and to prices from products which derive there from) used to quantify the expected future cash flows are estimated based on forward prices prevailing in the marketplace for the first four years and management’s long-term planning assumptions thereafter. The estimate of the future amount of production is based on assumptions related to the commodity future prices, lifting and development costs, market demand and other factors. The discount rate reflects the current market valuation of the time value of money and of the specific risks of the asset not reflected in the estimate of the future cash flows. Goodwill and other intangible assets with an indefinite useful life are not subject to amortization. The Company tests such assets at the cash generating unit level for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount. 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 recoverable amount 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 to remove tangible equipment and restore land or seabed require significant estimates in calculating the amount of the obligation and determining the amount required to be recorded presently in the Consolidated Financial Statements.

Estimating future asset retirement obligations is complex. It requires management to make estimates and judgments with respect to removal obligations that will come to term many years into the future and contracts and regulations are often unclear as to what constitutes removal. In addition, the ultimate financial impact of environmental laws and regulations is not always clearly known as asset removal technologies and costs constantly evolve in the countries where Eni operates, as do political, environmental, safety and public expectations. 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 obligation 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 (i.e. interest accretion) and any change in the estimates following the modification of future cash flows and discount rate adopted. The recognized asset retirement obligations are based on 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 business combinations requires the allocation of the purchase price to the various assets and liabilities of the acquired business at their respective fair values. Any positive residual difference is recognized as "Goodwill". Negative residual differences are credited to 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, production and other activities. They include legislations that implement 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. Management, considering the actions already taken, insurance policies obtained to cover environmental risks and provisions 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. However, 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 an unknown contamination;
(ii) |  | the results of the ongoing surveys and other possible effects of statements required by Decree No. 471/1999 of the Ministry for the Environment concerning the remediation of contaminated sites;
(iii) |  | the possible effects of future environmental legislations and rules;

106

##### Table of Contents

(iv) |  | the effects of possible technological changes relating to future remediation; and
(v) |  | the possibility of litigation and the difficulty of determining Eni’s liability, if any, against other potentially responsible parties with respect to such litigations and the possible insurance recoveries.

> Employee benefits

Defined benefit plans 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 trends, estimated retirement dates and mortality rates. The significant assumptions used to account for defined benefit plans 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. Indicators used in selecting the discount rate include rates of annuity contracts and rates of return on high quality fixed-income investments. 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 individual employees involved, based principally on available actuarial data; and (v) determination of the 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 unrecognized actuarial gains and losses 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 the profit or loss in their entirety.

> Contingencies

In addition, to accruing the estimated costs for environmental liabilities, asset retirement obligations and employee benefits, Eni accrues for all contingencies that are both probable and estimable. These other contingencies are primarily related to litigation and tax issues. Determining the appropriate amount to accrue is a complex estimation process that includes subjective judgments.

> Revenue recognition in the Engineering & Construction segment

Revenue recognition in the Engineering & Construction 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 the geographical region, market conditions in that region and any assessment that is necessary to estimate with sufficient precision the total future costs as well as the expected timetable. Requests of additional income, deriving from a change in the scope of 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 from additional costs incurred for reasons attributable to the client are included in the total amount of revenues when it is probable that the counterparty will accept them.

(2) |  | Beginning in 2009, the Company accounts for gains and losses on non-hedging commodity derivative instruments, including both fair value remeasurement and settled transactions, as items of operating profit. Prior period results have been restated accordingly.

The table below sets forth certain income statement items as a percentage of net sales from operations for the periods indicated.

| Year ended December 31,

OPERATING PROFIT |  | 17.1 |  | 14.5 |  | 16.4

2010 compared to 2009. Net profit attributable to Eni’s shareholders in 2010 was euro 6,318 million, an increase of euro 1,951 million from 2009, or 44.7%. This increase was driven by:

(i) |  | an improved operating performance (up by 33.6% from 2009) which was mainly reported by the Exploration & Production Division (up by 52%), reflecting a favorable trading environment. Improved operating results were also reported by the Engineering & Construction Division due to strong business trends, while the Petrochemicals and the Refining & Marketing Divisions achieved an improved performance in spite of difficult market conditions. Those gains were partly offset by sharply lower results recorded by the Gas & Power Division which was hit by a weak trading environment, and higher environmental charges up by approximately euro 1.1 billion mainly due to the recognition of a provision to account for the proposed global environmental settlement with the Italian Ministry for the Environment as discussed in the paragraph "Significant Transactions";
(ii) |  | recognition of higher inventory holding gains in particular in the Gas & Power Division. This increase is associated with rising gas prices which resulted in an increased carrying amount of gas inventories recorded under the weighted average cost method; and
(iii) |  | higher profits reported from equity-accounted and cost-accounted entities, including certain gains on divestments of assets (approximately euro 300 million).

108

##### Table of Contents

These increases were partly offset by higher income taxes (up euro 2,401 million compared to 2009) mainly reflecting higher income taxes currently payable by subsidiaries in the Exploration & Production Division operating outside Italy due to higher taxable profit.

2009 compared to 2008. Net profit pertaining to Eni in 2009 was euro 4,367 million, a decrease of euro 4,458 million from 2008, or 50.5%. This decrease was affected by the following factors:

(i) |  | a decreased operating profit reported by the Exploration & Production and Gas & Power segments due to lower oil and gas prices and a weaker gas demand. The Group results were also affected by higher amortization charges taken in connection with new investments. Those negatives were partly offset by recognition of lower inventory write-downs and impairments of property, plant and equipment particularly in the Refining & Marketing and Petrochemical segments. As a result, the Group consolidated operating profit was down euro 6,462 million, or 34.9%, from a year ago;
(ii) |  | lower profit (down euro 804 million) from non-consolidated entities that are accounted for under the equity or the cost method; and
(iii) |  | a higher consolidated tax rate up from 50.3% to 56% (up 5.7 percentage points), mainly due to new tax rules both in Italy and outside Italy which impacted taxes currently payable, charges accounted in the year which were excluded from tax calculations, and the circumstance that in 2008 the tax rate benefited from certain tax gains associated with an adjustment to deferred taxation amounting to euro 733 million as new tax provisions came into effect pertaining to both Italian and foreign subsidiaries.

> Discontinued Operations

Discontinued operations in 2010, 2009 and 2008 were immaterial.

> a) Total Revenues

Eni’s total revenues were euro 99,479 million, euro 84,345 million and euro 108,810 million for the year ended December 31, 2010, 2009 and 2008, respectively. Total revenues consist of net sales from operations and other income and revenues. Eni’s net sales from operations amounted to euro 98,523 million, euro 83,227 million and euro 108,082 million for the year ended December 31, 2010, 2009 and 2008, respectively, and its other income and revenues totaled euro 956 million, euro 1,118 million and euro 728 million, respectively, in these periods.

(1) |  | From January 1, 2009, results of the gas storage business, which were previously reported within the Exploration & Production segment, are reported within the Gas & Power segment reporting unit, following restructuring of Eni regulated gas businesses in Italy. As of that date, the results of the regulated businesses in Italy therefore include results of the Transport, Distribution, Re-gasification and Storage activities in Italy. Prior period results have been restated accordingly.
(2) |  | From January 1, 2009 Eni adopted IFRIC 13 "Customer Loyalty Programmes" which requires that the award points granted to clients within the related loyalty program be accounted as a separate component of the basic transaction, evaluated at their fair value and recognized as revenues when effectively used. Prior period results have been restated accordingly.
(3) |  | Intragroup sales are included in net sales from operations in order to give a more meaningful indication as to the volume of the activities to which sales from operations by segment may be related. The most substantial intragroup sales are recorded by the Exploration & Production segment. See Note 35 to the Consolidated Financial Statements for a breakdown of intragroup sales by segment for the reported years.

2010 compared to 2009. Eni’s net sales from operations (revenues) for 2010 (euro 98,523 million) increased by euro 15,296 million from 2009, or 18.4% from 2009, primarily reflecting higher realizations on oil, refined products and natural gas in U.S. dollar terms and the positive impact of the depreciation of the euro against the U.S. dollar.

Revenues generated by the Exploration & Production Division (euro 29,497 million) increased by euro 5,696 million, or 23.9%, mainly due to higher realizations in U.S. dollar terms (oil up 27.8%; natural gas up 7.1%) and the depreciation of the euro versus the U.S. dollar. Eni’s average liquids realizations decreased by 1.33 $/BBL to 72.76 $/BBL due to the settlement of certain commodity derivatives relating to the sale of 28.5 mmBBL. The latter trend is going to continue in 2011 due to current trends in Brent oil prices.

Revenues generated by the Gas & Power Division (euro 29,576 million) decreased by euro 871 million (or 2.9%) due to lower sales volumes in Italy (down 5.75 BCM, or 14.4%), partly offset by the positive impact of a slight recovery in spot and oil-linked gas prices due to a less unfavorable pricing environment compared to 2009 which are reflected in Eni’s revenues. Increased sales volumes were also recorded in key European markets.

Revenues generated by the Refining & Marketing Division (euro 43,190 million) increased by euro 11,421 million (or 36%) reflecting higher selling prices of refined products.

Revenues generated by the Petrochemical Division (euro 6,141 million) increased by euro 1,938 million (up 46.1%) mainly reflecting higher average selling prices (up 35.6%) and a recovery in sales volumes (up 10.9%, mainly in the elastomers business area) following stronger demand on end-markets compared to the particularly weak trading environment of the previous year.

Revenues generated by the Engineering & Construction business (euro 10,581 million) increased by euro 917 million, or 9.5%, from 2009, as a result of increased activities in the onshore and drilling business units.

2009 compared to 2008. Eni’s net sales from operations (revenues) for 2009 (euro 83,227 million) were down euro 24,855 million, or 23% from 2008, primarily reflecting lower realizations on oil, refined products and natural gas in U.S. dollar terms and lower sales volumes. These negatives were partly offset by the positive impact of the depreciation of the euro versus the U.S. dollar (down 5.3%).

Revenues generated by the Exploration & Production Division (euro 23,801 million) decreased by euro 9,241 million, or 28% from 2008, mainly due to lower realizations in U.S. dollars (oil down 32.2%; natural gas down 29.8%) reflecting a trading environment that was particularly adverse in the first nine months and the impact of

110

##### Table of Contents

energy parameters on gas prices and a fall in gas spot prices. This decrease reflected also lower sales volumes (down 9.2 million BOE, or 1.5%). These negatives were partly offset by the depreciation of the euro versus the U.S. dollar.

Revenues generated by the Gas & Power Division (euro 30,447 million) decreased by euro 6,615 million, or 17.8% from 2008, mainly due to lower gas prices reflecting trends in energy parameters, as well as lower volumes sold in Italy (down 12.8 BCM, or 24.2%) due to the impact of the economic downturn. These negatives were partly offset by increased sales outside Italy due to contribution of the Distrigas acquisition (up 12.02 BCM).

Revenues generated by the Refining & Marketing Division (euro 31,769 million) decreased by euro 13,248 million, or 29.4% from 2008, reflecting lower product prices and lower sales volumes (down 10%), that were partially offset by the impact of the depreciation of the euro versus the U.S. dollar.

Revenues generated by the Petrochemical Division (euro 4,203 million) decreased by euro 2,100 million, or 33.3% from 2008, mainly reflecting lower sales prices (down 26%) due to lower international prices for crude oil and refined products and a decline in volumes sold due to lower end-markets demand that was driven down by the economic downturn.

Revenues generated by the Engineering & Construction business (euro 9,664 million) increased by euro 488 million, or 5.3% from 2008, as a result of the large number of oil and gas projects that were started during the upward phase of the oil cycle.

> b) Operating Expenses

The table below sets forth the components of Eni’s operating expenses for the periods indicated.

| Year ended December 31,

|  | 2008 |  | 2009 |  | 2010

|  | (euro million)

Purchases, services and other |  | 76,350 |  | 58,351 |  | 69,135
Payroll and related costs |  | 4,004 |  | 4,181 |  | 4,785
Operating expenses |  | 80,354 |  | 62,532 |  | 73,920

2010 compared to 2009. Operating expenses for the year (euro 73,920 million) increased by euro 11,388 million from 2009, up 18.2%, reflecting primarily higher supply costs of purchased oil, gas and petrochemical feedstocks reflecting trends in the trading environment, the depreciation of the euro against the U.S. dollar, as well as higher operating expenses reported by the upstream activities.

Purchases, services and other costs include environmental and other risk provisions for an overall amount of euro 1,291 million mainly associated with an environmental provision recorded to account for a proposed global settlement on certain environmental issues (euro 1,109 million) filed with the Italian Ministry for the Environment, which is disclosed in the paragraph "Significant Transactions" below.

Payroll and related costs (euro 4,785 million) increased by euro 604 million, or 14.4%, mainly due to higher unit labor cost in Italy and outside Italy, partly due to exchange rate translation differences, the increase in the average number of employees outside Italy (following higher activity levels in the Engineering & Construction business), as well as increased provisions for redundancy incentives (euro 423 million in 2010) including a provision representing the charge to be borne by Eni as part of a personnel mobility program in Italy for the period 2010-2011. These increases were partly offset by a decrease in the average number of employees in Italy.

2009 compared to 2008. Operating expenses for 2009 (euro 62,532 million) were down euro 17,822 million from 2008, or 22.2%, reflecting primarily lower supply costs of purchased oil, gas and petrochemical feedstocks, partially offset by the depreciation of the euro against the U.S. dollar.

Purchases, services and other included environmental and other risk provisions, impairments of certain current and non-current assets, other than tangible and intangible assets, amounting to euro 537 million. They also included a charge amounting to euro 250 million which was estimated on the basis of the possible resolution of an investigation related to the TSKJ Consortium based on the current status of the ongoing discussions with U.S. Authorities.

Payroll and related costs (euro 4,181 million) increased by euro 177 million from 2008 (up 4.4%) mainly due to higher unit labor cost in Italy and outside Italy, partly due to exchange rate translation differences, the increase in

111

##### Table of Contents

the average number of employees outside Italy, following the consolidation of Distrigas in the Gas & Power Division, increased personnel in the Engineering & Construction and Exploration & Production businesses due to higher activity levels, as well as increased provisions for redundancy incentives. These increases were partially offset by a decrease in the average number of employees in Italy.

> c) Depreciation, Depletion, Amortization and Impairments

The table below sets forth a breakdown of depreciation, amortization and impairments by business segment for the periods indicated.

| Year ended December 31,

|  | 2008 |  | 2009 |  | 2010

|  | (euro million)

Exploration & Production (1) |  | 6,678 |  |  | 6,789 |  |  | 6,928 |
Gas & Power |  | 797 |  |  | 981 |  |  | 963 |
Refining & Marketing |  | 430 |  |  | 408 |  |  | 333 |
Petrochemicals |  | 116 |  |  | 83 |  |  | 83 |

Total depreciation, depletion and amortization |  | 8,422 |  |  | 8,762 |  |  | 8,881 |
Impairments |  | 1,393 |  |  | 1,051 |  |  | 698 |
|  | 9,815 |  |  | 9,813 |  |  | 9,579 |

(1) |  | Exploratory expenditures of euro 1,199 million, euro 1,551 million and euro 2,057 million are included in these amounts relative to the years 2010, 2009 and 2008, respectively.
(2) |  | This item concerned mainly intra-group sales of goods, services and capital assets recorded at period end in the equity of the purchasing business segment.

2010 compared to 2009. In 2010, depreciation, depletion and amortization charges amounted to euro 8,881 million, representing an increase of euro 119 million from 2009, or 1.4%. The Exploration & Production Division recorded higher charges (up euro 139 million) due to increased development activities as new fields were brought into production and higher expenditures were made in order to support production levels in producing fields. Those were partly offset by lower exploration expenditures. Also the Engineering & Construction business recorded higher charges (up euro 80 million) as new vessels and rigs were brought into operation. The decrease recorded in the Refining & Marketing Division reflected a review of the residual useful lives of refineries and related facilities, with an impact of euro 76 million. In doing so, the Company believes that it aligned with practices prevailing among integrated oil companies, particularly the European companies. In the Gas & Power Division, the impact of new investments entered into operation was offset by the revision of the useful lives of gas pipelines (from 40 to 50 years), as revised by the Authority for Electricity and Gas for tariff purposes, from January 1, 2010, with an impact of euro 31 million.

In 2010, impairment charges of euro 698 million mainly regarded an impairment charge of goodwill allocated to the European gas marketing cash generating unit in the Gas & Power Division. The impaired goodwill derived from the acquisition of the Belgian company Distrigas that was made in 2009. Management forecasts that weak demand growth and continuing oversupply will continue to weigh on the recovery of the European gas sector in the next few years. Rising competitive pressures will pressure unit margins on gas sales and reduce selling outlets. To factor in those trends, management revised downward with respect to past years, future projections for returns and cash flows of the Company’s gas business for the next four years. Particularly, the European market business unit is expected to be negatively affected by lowering marketing margins over the next four years. This reflects ongoing development of highly liquid spot markets for gas and the fact that spot prices have increasingly become the prevailing reference price for contractual formulas in supplies outside Italy whereas Eni’s purchase costs for gas are mainly indexed to the price of oil and refined products. Trends in spot prices as compared to those in oil-linked purchase costs have been de-coupling until recently resulting in negative spreads during the course of 2010; management expects that those negative trends will not re-couple until 2014 at the earliest. In the 2010 Consolidated Financial Statements, management recognized an impairment loss amounting to euro 426 million associated with goodwill of the European gas business unit considering weak 2010 results and a reduced outlook for profitability as discussed above. Impairment charges of oil and gas properties in the Exploration & Production Division were recorded for significantly lower amount than in the previous two years. Impairments were triggered by a changed

pricing environment and downward reserve revisions which mainly pertained to gas properties in the USA with proved and unproved reserves. Minor impairment losses were recorded on assets impaired in previous reporting periods in the Refining & Marketing and Petrochemical Divisions as capital expenditures made in 2010 were completely written-off as Eni does not expect improving profitability in the underlying business units (For further information see "Item 18 – Consolidated Financial Statements – Note 14 – Tangible and Intangible assets").

2009 compared to 2008. In 2009, depreciation, depletion and amortization charges (euro 8,762 million) increased by euro 340 million, or 4% from 2008, mainly in: (i) the Gas & Power Division (up euro 184 million) reflecting consolidation of assets acquired and entry into service of new investments; and (ii) the Exploration & Production segment (up euro 111 million) where higher charges were associated with the depreciation of the euro against the U.S. dollar, rising development activities reflecting consolidation of acquired oil and gas properties and increased expenditures to develop new complex fields and projects. These negatives were partly offset by lower exploration expenses. The Engineering & Construction segment also increased amortization charges in connection with the entry into service of new assets.

In 2009, impairments (euro 1,051 million) which were down euro 342 million, mainly related to: (i) impairment charges recorded on proved and unproved properties in the Exploration & Production Division due to downward reserve revisions and cost increases mainly recorded in the Gulf of Mexico, Australia, Congo and Egypt; (ii) refinery plants due to expectations of poor refining margins reflecting the industry weak fundamentals and plants’ specific factors such as low complexity. Also impairments of goodwill were recognized on marketing assets acquired in Central-Eastern Europe and certain other marketing assets in the Refining & Marketing Division, in the light of a downsizing of growth expectations on certain markets; and (iii) a number of plants in the Petrochemical Division due to a weak outlook for pricing/margins as a result of lower petrochemical products demand, excess capacity and higher competitive pressures.

(1) |  | From January 1, 2009, results of the gas storage business, which were previously reported within the Exploration & Production segment, are reported within the Gas & Power segment reporting unit, following restructuring of Eni regulated gas businesses in Italy. As of that date, the results of the regulated businesses in Italy therefore include results of the Transport, Distribution, Re-gasification and Storage activities in Italy. Prior period results have been restated accordingly.
(2) |  | From 2010 certain environmental provisions incurred by the parent company Eni SpA due to inter-company guarantees on behalf of Syndial have been reported within the segment reporting unit "Other activities" rather than the segment "Corporate and financial companies". Data for the years 2008 and 2009 have been restated accordingly for the following amounts: euro 120 million and euro 54 million, respectively.
(3) |  | From 2009, the Company accounts gains and losses on non-hedging commodity derivatives instruments, including both fair value re-measurement and settled transactions, as items of operating profit. Prior period results have been restated accordingly.

Exploration & Production. Operating profit in 2010 amounted to euro 13,866 million, up euro 4,746 million from 2009, or 52%, due to higher liquids and gas realizations in U.S. dollar terms (up by 27.8% and 7.1%, respectively). The result also reflected: (i) a positive impact associated with the depreciation of the euro against the U.S. dollar, for an estimated amount of euro 400 million; (ii) the recognition of lower asset impairments; and (iii) lower exploration expenditures. These positives were partly offset by increased operating expenses and amortizations charges reflecting new fields entered into operation and activities to improve production rates in existing fields, and higher provisions for redundancy incentives (up euro 66 million).

In 2010, liquids and gas realizations increased on average by 18.6% in U.S. dollar terms, driven by higher oil prices for market benchmarks (Brent crude price increased by 29.2%) and, to a lower extent, higher gas prices which were up by 7.1% on average. Eni’s oil realizations increased on average by 27.8% driven by a favorable market environment. Eni’s average liquids realizations were negatively impacted for an amount of 1.33 $/BBL on average due to the settlement of certain commodity derivatives relating the sale of 28.5 mmBBL in the year at contractually fixed prices. This was part of a derivative transaction the Company entered into to hedge exposure to volability of future cash flows expected from the sale of a portion of the Company’s proved reserves for an original amount of approximately 125.7 mmBBL in the 2008-2011 period. As of December 31, 2010, the residual amount of that hedging transaction was 9 mmBBL.

Liquid realizations and the impact of commodity derivatives were as follows:

| Full Year

|  | 2008 |  | 2009 |  | 2010

Sales volumes |  | (mmBBL) |  | 364.3 |  |  | 373.5 |  |  | 357.1 |
Sales volumes hedged by derivatives (cash flow hedge) |  |  |  | 46.0 |  |  | 42.2 |  |  | 28.5 |
Total price per barrel, excluding derivatives |  | ($/BBL) |  | 88.17 |  |  | 56.98 |  |  | 74.09 |
Realized gains (losses) on derivatives |  |  |  | (4.13 | ) |  | (0.03 | ) |  | (1.33 | )
Total average price per barrel |  |  |  | 84.05 |  |  | 56.95 |  |  | 72.76 |

Operating profit in 2009 amounted to euro 9,120 million, down euro 7,119 million from 2008, or 43.8%, reflecting lower realizations in U.S. dollars (oil down 32.2%; natural gas down 29.8%), and reduced production sales volumes (down 9.2 mmBOE, or 1.5%). These negatives were partly offset by: (i) positive currency translation differences which were reported by subsidiaries which adopted the U.S. dollar as functional currency, as the euro depreciated on average by 5.3%. This had an estimated positive impact of euro 500 million; (ii) recognition of lower asset impairments (down euro 234 million); and (iii) gains recorded on the divestment of certain exploration and production assets as part of the agreements signed with Suez.

Liquids and gas realizations for the year decreased on average by 31.2% in U.S. dollar terms driven by lower oil prices for market benchmarks (Brent crude price decreased by 36.6%), partly offset by an improved product mix of Eni’s crudes (down 32.2%). Average oil realizations were barely unchanged, due to the settlement of certain non-strategic commodity derivatives relating to the sale of 42.2 mmBBL.

In 2009, the impact of those cash flow hedges was immaterial as the increase in liquids realizations by 0.45 $/BBL as a result of the sale of 31.6 mmBBL at the hedged price recorded in the first nine months was absorbed by

114

##### Table of Contents

a reduction on average by 1.46 $/BBL from the sale of 10.6 mmBBL in the fourth quarter, reflecting the inversion in oil prices trends. The derivatives were entered into to hedge exposure to fluctuations in future cash flows expected from the sale of a portion of the Company’s proved reserves, in connection with the acquisition of oil and gas assets in Congo and in the Gulf of Mexico. When entered into, those hedging transactions originally covered an amount of approximately 125.7 mmBBL in the 2008-2011 period, which by the end of 2009 has decreased to approximately 37.5 mmBBL.

In 2009, average gas realizations were down 29.8%, driven by time-lags between movements in oil prices and their effect on gas prices pursuant to pricing formulae and by weak spot prices.

Gas & Power. In 2010, the Gas & Power Division reported operating profit of euro 2,896 million, a decrease of euro 791 million from 2009, down 21.5%, due to a lower performance delivered by the Marketing business which was down by 63.7%. This was partly offset by a better performance achieved by the Italian regulated businesses (up by 12.7%). The negative performance in marketing operations was mainly due to: (i) increasing competitive pressures in Italy, due to oversupply conditions in the marketplace and sluggish demand growth, resulting in both sharply lower gas sales (down by 14.4% and 19.5% to Italian customers and Italian wholesalers importers, respectively) and price reductions to customers during the marketing campaign for the new thermal year beginning on October 1, 2010; (ii) outside Italy, the persistence of unprofitable differentials between oil-linked gas purchase costs provided in Eni’s long-term gas supply contracts and spot prices recorded at European hubs which have become a prevailing reference benchmark for selling prices; (iii) the impairment of goodwill attributed to the European marketing cash generating unit (euro 426 million), based on 2010 results and a reduced profitability outlook for this business; (iv) a negative change in mark-to-market evaluation of certain commodity derivatives which are recorded against profit as they lack formal requirements to be designated as hedges under applicable accounting standards; and (v) a reversal in trend of certain energy parameters to which gas purchase and selling prices are indexed, mainly in sales to residential users.

These negatives were partly offset by: (i) the recording of higher inventory holding gains due to the impact of rising gas prices on inventories stated at the weighted average cost of supplies or the net realizable value, whichever is lower; and (ii) a non-recurring gain amounting to euro 270 million related to the favorable settlement of an antitrust proceeding resulting in a provision accrued in previous reporting periods being reversed almost entirely to 2010 profit. The provision was originally accrued to take into account a resolution of the Italian Antitrust Authority, who charged Eni with anti-competitive behavior for having allegedly refused third party access to the pipeline for importing natural gas from Algeria.

Operating profit in 2009 amounted to euro 3,687 million, a decrease of euro 343 million compared with 2008, down by 8.5%. This decrease was principally due to the following factors: (i) lower results from marketing operations in Italy as sales volumes of gas declined by 12.83 BCM, or 24.3%, due to the impact of lower gas demand and competitive pressures, also impacting selling margins. The negative margin/volume performance in marketing operations was incurred notwithstanding a positive impact associated with the renegotiation of certain long-term supply contracts; (ii) a negative impact on gas inventory valuation associated with falling gas prices which resulted in a decreased carrying amount of gas inventories recorded at the weighted average cost or net realizable value, whichever is lower; and (iii) a provision accounted in the LNG business associated with poor market perspectives in the USA. These negatives were partly offset by: (i) the circumstance that sales to residential customers in Italy and other customers consuming less than 200,000 CM/y benefited from the regulatory indexation mechanism whereby the selling price was updated with a certain delay to changed market conditions, resulting in higher margins on those sales. Management believes that this mechanism will have an opposite effect on the Company’s results in coming quarters; and (ii) positive mark-to-market evaluation of certain commodity derivatives which are recorded against profit as they lack formal requirements to be designated as hedges under applicable accounting standards. The International Transport business recorded a drop in operating profit; while regulated businesses in Italy increased their result.

The table below sets forth break-down of operating profit by businesses in the Gas & Power Division:

##### Table of Contents

Refining & Marketing. In 2010, the Refining & Marketing segment reported an operating profit of euro 149 million, compared to the prior-year loss of euro 102 million. The improvement reflected a less adverse refining scenario with Eni’s complex refineries helped by widening price differentials between sour and sweet crudes and better spreads of middle distillates to heating fuel. Refining margins still remained unprofitable as high oil feedstock prices were only partially transferred to final prices of refined products pressured by weak industry fundamentals. The Eni Refining business also benefited from cost efficiencies and various optimization measures in supply and refining activities, and integration of refinery cycles whereby the Gela refinery have begun processing heavy residues from Taranto throughputs thus enabling to reap cost savings and margins improvements. The Marketing business was affected by rapidly rising supply costs that were only partially transferred to prices at the pump, and lower retail sales in Italy. These negatives were partly offset by higher sales on European networks. Results of Refining & Marketing Division also benefited from the circumstance that in 2009 material impairment charges were recorded to align the carrying amounts of unprofitable refining and marketing assets to their projected recoverable amounts (down by euro 313 million).

In 2009, the Refining & Marketing segment reported an operating loss of euro 102 million, which represented a significant improvement (up euro 886 million) compared to 2008 when a loss of euro 988 million was recorded. The improvement reflected the circumstance that an inventory write-down amounting to euro 1,199 million was recorded in 2008 as year end inventories of oil and products were aligned to net realizable values prevailing on the marketplace at the time of the assessment which coincided with the low of the oil cycle. In 2009, an inventory holding gain amounting to euro 792 million was recognized reflecting the impact of a recovery in prices of crude oil and products on year end valuation of inventories according to the average cost method of inventory accounting. When excluding the inventory impacts, the Refining & Marketing segment reported underlying losses mainly due to sharply lower refining margins. Those were affected by an unfavorable trading environment due to weak end-prices of products depressed by poor demand, excess inventory of finished products on the marketplace, in particular diesel oil, whose spread on raw material reached historical lows in the fourth quarter, and excess capacity. As a result, product price did not absorb the purchase price of oil-based feedstock. Also narrowing price differentials between heavy and light crude qualities negatively affected Eni’s complex throughputs by reducing cost-advantages associated to conversion: (i) lower operating performance delivered by the Marketing activities affected by weak demand in wholesale markets in Italy and retail European markets; and (ii) higher asset impairment charges recorded in the light of the negative outlook for the refining industry and a downsizing of growth expectations on certain markets.

Petrochemicals. In 2010, the Petrochemical Division recorded a sharp reduction in its operating loss which was down by 87.3% from the year-earlier (from a loss of euro 675 million in 2009 to a loss of euro 86 million in 2010). This positive result reflected better market conditions and a recovery in demand which drove improved product margins and higher sales (up by 10.9% mainly in the elastomers business area). Profitability was also supported by cost efficiencies. An inventory holding gain amounting to euro 105 million was recognized (compared with a loss of euro 121 million in 2009) reflecting the impact of higher oil-based feedstock and commodity prices on year end valuation of inventories according to the average cost method of inventory accounting, as well as lower asset impairments (down by euro 69 million).

In 2009, the Petrochemical segment reported an operating loss in the amount of euro 675 million, which represented an improvement of euro 170 million compared to 2008 mainly due to lower impairment losses (down euro 157 million from 2008). The segment’s results continued to be affected by weak industry fundamentals due to poor demand, excess capacity and competitive pressures. As a result, the segment reported unprofitable margins on products and lower sales volumes (down 8.9%).

Engineering & Construction. Operating profit in 2010 amounted to euro 1,302 million, an increase of euro 421 million, or 47.8% compared to 2009. This increase was driven by a positive operating performance reported by the Onshore Construction and Offshore Drilling business areas reflecting higher activity levels and higher margins on the works performed. The utilization rate of the Perro Negro 6 jack-up and the semisubmersibles Scarabeo 3 and 4 increased. In addition, the comparison with 2009 benefited from the circumstance that in 2009 a charge amounting to euro 250 million was recorded to settle the TSKJ legal proceeding "Item 8 – Financial Information – Legal Proceedings" for further details.

Operating profit in 2009 amounted to euro 881 million, a decrease of euro 164 million, or 15.7% compared to 2008. This decrease related to a non-recurring item represented by a charge amounting to euro 250 million that was the estimated cost of a possible resolution of the investigation related to the TSKJ Consortium based on the current status of ongoing discussions with U.S. Authorities (See "Item 18 – Note 34 of the Financial Statements"). Although the charge was recognized in the segment results of the Engineering & Construction business as it related to a project to build gas liquefaction plants, it will be fully incurred by Eni and Saipem’s minorities will be left unaffected due to Eni’s contractual obligations to indemnify Saipem undertaken in connection with the divestiture of Snamprogetti SpA, whose subsidiary Snamprogetti Netherlands BV participates to the TSKJ venture. See "Item 8 – Financial Information – Legal Proceedings" for further details. When excluding the impact of the charge, the segment reported an improved operating performance recorded in all business areas reflecting steady revenue

growth and stable profitability as a result of the large number of oil and gas projects that were started during the upward phase of the oil cycle.

Other activities. This reporting segment includes the results of operations of Eni’s subsidiary Syndial which runs minor petrochemical activities and reclamation and decommissioning activities pertaining to certain businesses which Eni exited in past years.

Other activities reported an operating loss of euro 1,384 million for 2010, representing a sharply higher increase of euro 948 million compared to the loss recorded in 2009 (euro 436 million) mainly due to higher environmental provisions recorded to account for a proposed global transaction on certain environmental issues (euro 1,109 million) filed with the Italian Ministry for the Environment, which is disclosed in the paragraph "Significant Transactions" below.

Other activities reported an operating loss of euro 436 million for 2009, representing an improvement of euro 30 million, or 6.4%, compared to the loss recorded in 2008 (euro 466 million) mainly due to lower environmental charges.

Corporate and financial companies. These activities are mainly cost centers which comprise corporate activities and central treasury departments and financial and other subsidiaries that provide a range of financial and business support services to Group companies, including financing of Eni’s projects around the world, information technology, employee selection, training and retention, real estate and other general purposes services.

The aggregate Corporate and financial companies reported an operating loss of euro 361 million for 2010, representing a reduction of euro 59 million, compared to the loss recorded in 2009 (euro 420 million), mainly reflecting the implementation of cost efficiency measures.

The aggregate Corporate and financial companies reported an operating loss of euro 420 million for 2009, representing a reduction of euro 203 million, compared to the loss recorded in 2008 (euro 623 million), mainly reflecting the circumstance that in 2008 a contribution of euro 200 million to the solidarity fund pursuant to Italian Law Decree No. 112/2008 to be used to subsidize the gas bills for residential uses of less affluent citizens and higher environmental provisions were accounted for.

> e) Net Finance Expense

The table below sets forth a breakdown of Eni’s net finance expense for the periods indicated:

| Year ended December 31,

|  | 2008 |  | 2009 |  | 2010

|  | (euro million)

Gain (loss) on derivative financial instruments |  | (427 | ) |  | (4 | ) |  | (131 | )
Exchange differences, net |  | 206 |  |  | (106 | ) |  | 92 |
Interest income |  | 87 |  |  | 33 |  |  | 18 |
Finance expense on short and long-term debt |  | (993 | ) |  | (753 | ) |  | (766 | )
Finance expense due to the passage of time |  | (249 | ) |  | (218 | ) |  | (251 | )
Income from equity instruments |  | 241 |  |  | 163 |  |  |  |
Other finance income and expense, net |  | 259 |  |  | 111 |  |  | 124 |
|  | (876 | ) |  | (774 | ) |  | (914 | )
Finance expense capitalized |  | 236 |  |  | 223 |  |  | 187 |
|  | (640 | ) |  | (551 | ) |  | (727 | )

2010 compared to 2009. In 2010, net finance expense increased by euro 176 million to euro 727 million from 2009, mainly due to the circumstance that in 2009 a finance gain of euro 163 million was recorded under "Income from equity instruments" due to the contractual remuneration on the 20% interest in OAO Gazprom Neft, earned until such interest was divested on April 24, 2009. Higher losses were recognized in connection with fair value evaluation through profit and loss of certain derivative instruments on exchange rates (up euro 127 million) that did not meet all formal criteria to be designated as hedges under IFRS. Those losses were more than offset by net positive exchange rate differences (euro 198 million). The item "Exchange differences, net" includes a currency adjustment, amounting to euro 33 million, related to the loss provision accrued in the 2009 financial statements to take account of the TSKJ proceeding. Finance charges on finance debt were substantially in line with the previous

117

##### Table of Contents

year, as the impact associated with increased average net borrowings was offset by lower interest rates on both euro-denominated and U.S. dollar loans (down 0.4 percentage points the Euribor and the Libor rate).

2009 compared to 2008. In 2009, net finance expenses were euro 551 million, a decrease of euro 89 million from 2008. This was mainly due to increased losses on exchange differences (up euro 312 million) offset by gains recognized in connection with fair value evaluation through profit and loss of certain derivative instruments on exchange rates (up euro 423 million) which were recorded against profit as they did not qualify for hedge accounting. In addition, lower finance charges were incurred as interest rates on euro-denominated finance debt (Euribor down 3.4 percentage points) and on U.S. dollar loans (Libor down 2.2 percentage points) were down. A gain from an interest amounting to euro 163 million was recorded (euro 241 million in 2008) related to the contractual remuneration of 9.4% on the 20% interest in OAO Gazprom Neft, calculated up to April 24, 2009, when Gazprom paid for the call option exercised on April 7, 2009.

> f) Net Income from Investments

2010 compared to 2009. Net income from investments in 2010 was a net gain of euro 1,156 million and mainly related to: (i) Eni’s share of profit of entities accounted for with the equity method (euro 537 million), mainly in the Gas & Power and Exploration & Production Divisions; (ii) dividends received by entities accounted for at cost (euro 264 million), mainly relating to Nigeria LNG Ltd; and (iii) gains on disposal of interests (euro 332 million) related to the full divestment of Società Padana Energia (euro 169 million), a 25% stake in GreenStream (euro 93 million) including a gain from revaluing the residual interest in the venture, a 100% interest in the Belgian company Distri RE SA (euro 47 million) as well as a non-strategic interest of the Engineering & Construction Division (euro 17 million).

2009 compared to 2008. Net income from investments in 2009 was a net gain of euro 569 million and mainly related to: (i) the share of profit of entities accounted for with the equity method (euro 393 million), mainly in the Gas & Power and Exploration & Production Divisions. Gains also comprised a gain on Eni’s 60% interest in Artic Russia (euro 100 million) due to the divestment of a 51% stake in OOO Severenergia to Gazprom based on the call option exercised by the Russian company; and (ii) dividends received by entities accounted for at cost (euro 164 million), mainly related to Nigeria LNG Ltd.

> g) Taxes

2010 compared to 2009. In 2010, income taxes amounted to euro 9,157 million, up euro 2,401 million from a year ago, or 35.5%, mainly reflecting higher income taxes currently payable by subsidiaries in the Exploration & Production Division operating outside Italy due to higher taxable profit.

The Group consolidated tax rate was lower compared to 2009, down from 56% to 55.4% (down 0.6 percentage points). This reduction was due to:

(i) |  | the recognition of a gain amounting to euro 270 million reflecting the favorable outcome of an antitrust proceeding which was a non-taxable item; and
(ii) |  | the circumstance that in 2009 a non-recurring charge amounting to euro 250 million was recorded to settle the TSKJ legal proceedings which was a non-deductible tax item. In addition the payment of a balance for prior-year income taxes amounted to euro 230 million in Libya as new rules come into effect which reassessed revenues for tax purposes and a lower capacity for Italian companies to deduct the cost of goods sold associated with lower gas inventories at year end (euro 64 million) was incurred, partly offset by net tax gains of euro 150 million.

Those positive effects on the Group tax rate were partly offset by a higher percentage of taxable income reported by foreign subsidiaries in the Exploration & Production Division which bear a higher tax rate than the Group average tax rate.

2009 compared to 2008. In 2009, income taxes amounted to euro 6,756 million, down euro 2,936 million from a year ago, or 30.3%, mainly reflecting reduced income taxes currently payable recorded by subsidiaries in the Exploration & Production Division operating outside Italy due to lower taxable profit.

The Group reported consolidated tax rate was higher compared to 2008, from 50.3% to 56% (up 5.7 percentage points). A number of factors explained the increase:

(i) |  | the impact of recently enacted tax regulations that provided a one-percentage point increase in the tax rate applicable to Italian companies in the energy sector and enactment of a supplemental tax rate to be added to the Italian statutory tax rate resulting in higher taxes currently payable, amounting to euro 239 million for the full year;

118

##### Table of Contents

(ii) |  | the recognition of a non-recurring item which was a non-deductible tax item, represented by a charge amounting to euro 250 million that was the estimated cost of the possible resolution of the investigation related to the TSKJ Consortium based on the current status of ongoing discussions with U.S. Authorities. The matter is fully-disclosed in the section "Legal Proceedings" in Note 34 to the Consolidated Financial Statements;
(iii) |  | the payment of a balance for prior-year income taxes amounting to $310 million (or euro 230 million) in Libya as new rules came into effect which reassessed revenues for tax purposes;
(iv) |  | a write-down of certain deferred tax assets associated with upstream properties to factor in expected lower profitability (down euro 72 million);
(v) |  | a lower capacity for Italian companies to deduct the cost of goods sold associated with lower gas inventories at year end (down euro 64 million); and
(vi) |  | the circumstance that in 2008 certain tax gains associated with an adjustment to deferred taxation amounting to euro 733 million were recorded as new tax provisions came into effect pertaining to both Italian and foreign subsidiaries.

These higher tax expenses were partly offset by recognition of a positive adjustment to deferred taxation following alignment of the tax base of certain oil and gas properties to their higher carrying amounts by paying a one-off tax, as part of the reorganization of upstream activities in Italy, and lower income taxes currently payable as new rules came into effect providing for the partial deduction of an Italian local tax from taxable income, also applying to previous fiscal years (for a total positive impact of euro 222 million).

> h) Non-controlling Interest

2010 compared to 2009. Net profit pertaining to non-controlling interest was euro 1,065 million, up from euro 950 million in 2009, and concerned primarily Snam Rete Gas SpA (euro 537 million) and Saipem SpA (euro 503 million).

2009 compared to 2008. Non-controlling interest was euro 950 million, up euro 217 million from 2008, or 29.6%, and concerned primarily Saipem SpA (euro 567 million) and Snam Rete Gas SpA (euro 369 million).

Liquidity and Capital Resources

Eni’s cash requirements for working capital, dividends to shareholders, capital expenditures and acquisitions over the past three years were financed primarily by a combination of funds generated from operations, borrowings and divestments of non-strategic assets. The Group continually monitors the balance between cash flow from operating activities and net expenditures targeting a sound and well-balanced financing structure.

> Analysis of Certain Components of Eni’s Change in Net Borrowings

In 2010, adjustments to reconcile net profit to net cash provided by operating activities mainly related to non-monetary charges and gains amounting to euro 9,024 million, which primarily regarded depreciation, depletion amortization and impairment charges of tangible and intangible assets (euro 9,579 million), gains on disposals of euro 552 million mainly relating to divestiture of certain interests as discussed under the caption "f) Net income from investments and properties in the Exploration & Production Division" and movements in net working capital. Adjustments to net profit also included income taxes (euro 9,157 million) and interest expenses (euro 571 million) accrued in the year as opposed to amounts actually paid.

Net profit for 2009 was adjusted to take into account non-monetary charges and gains amounting to euro 9,117 million, which primarily regarded depreciation, depletion amortization and impairment charges of tangible and intangible assets (euro 9,813 million), gains on disposals and movements in net working capital. Adjustments to net profit also included income taxes (euro 6,756 million) and interest expenses (euro 603 million) occurred in 2009 as opposed to amounts paid in the year.

> a) Changes in Working Capital related to Operations

In 2010, changes in working capital absorbed cash flows amounting to a negative euro 1,720 million as a result of: (i) increasing oil, gas and petroleum products inventories (up euro 1,150 million) due to the impact of rising oil prices on inventories stated at the weighted average cost; and (ii) cash pre-payments amounting to euro 1,238 million made to the Company’s suppliers of gas under long-term gas supply contracts whereby the Company has the contractual obligation to lift minimum annual quantities of gas or, in case of failure, pre-pay the whole price or a portion of the price of those quantities as provided by the so-called take-or-pay clause. The Company recognized among its assets a deferred cost to account for those pre-paid volumes of gas. For further details on that asset see "Item 18 – Note 14 – Other non current assets – in Notes to the Consolidated Financial Statements".

These negatives were partly offset by an increased balance between trade payables and receivables also resulting by reduced trade receivables relating to the transfer of certain receivables without recourse to factoring institutions, amounting to euro 1,279 million due in 2011, increasing Group cash inflows.

In 2009, changes in working capital absorbed flows amounting to a negative euro 1,195 million as a result of a decreased balance between trade payables and receivables.

Acquisitions of investments and businesses totaled euro 410 million in 2010 and euro 2,323 million in 2009.

In 2010, disposals amounted to euro 1,113 million and mainly related to: (i) a second tranche of the divestment to Gazprom of a 51% stake in the joint venture OOO SeverEnergia by the shareholding company Artic Russia which is jointly participated by Eni and Enel (60% and 40% being their respective interests), following the exercise of a call option by the Russian company.

In 2009, disposals primarily related to: (i) the divestment of a 20% interest in Gazprom Neft following exercise of a call option by Gazprom on April 7, 2009, amounting to euro 3,070 million. The exercise price of the call option was equal to the bid price ($3.7 billion) as adjusted by subtracting dividends distributed and adding the contractual annual remuneration of 9.4% on capital employed and certain financial collateral expenses; (ii) the divestment to Gazprom of a 51% stake in the joint venture OOO SeverEnergia (Eni 60%). Eni’s share of the transaction is worth $940 million of which $230 million were collected as of year end, which corresponded to euro 155 million at the exchange rate on the transaction date. The remaining part of the divestment was collected by March 31, 2010; and (iii) other disposals relating to non-strategic oil and gas properties following agreements signed with Suez.

> c) Dividends paid and Changes in Non-controlling Interests and Reserves

In 2010, dividends paid and changes in non-controlling interest and reserves (euro 4,099 million) mainly related to: (i) cash dividends to Eni shareholders (of which euro 1,811 million related to the balance for the dividend relating the fiscal year 2009 and euro 1,811 million as an interim dividend for fiscal year 2010); and (ii) the distribution of dividends to non-controlling interest by Snam Rete Gas SpA and Saipem SpA (euro 506 million) and other consolidated subsidiaries (euro 8 million).

In 2009, dividends paid and changes in non-controlling interest and reserves (euro 2,956 million) related mainly to the dividend distribution to Eni shareholders for euro 4,166 million (of which euro 2,355 million related to the balance for the fiscal year 2008 and euro 1,811 million as an interim dividend for fiscal year 2009) and the distribution of dividend to non-controlling interest by Snam Rete Gas SpA and Saipem SpA (euro 335 million) and other consolidated subsidiaries (euro 15 million). These outflows were partly offset by the subscription by Snam Rete Gas SpA minorities of their respective share of a capital increase amounting to euro 1,542 million as part of

Eni’s reorganization of its regulated businesses in Italy. This transaction is outlined in "Item 4 – Significant business and portfolio developments for the year".

> Financial Condition

In assessing its capital structure, Eni uses net borrowings, which is a non-GAAP financial measure. Eni calculates net borrowings as total finance debt (short-term and long-term debt) derived from its Consolidated Financial Statements prepared in accordance with IFRS as endorsed by IASB less: cash, cash equivalents and certain highly liquid investments not related to operations including, among others, non-operating financing receivables and securities not related to operations. Non-operating financing receivables consist mainly of deposits with banks and other financing institutions and deposits in escrow. Securities not related to operations consist primarily of government bonds and securities from financing institutions. These assets are generally intended to absorb temporary surpluses of cash as part of the Company’s ordinary management of financing activities.

Management believes that net borrowings is a useful measure of Eni’s financial condition as it provides insight about the soundness of Eni’s capital structure and the ways by which Eni’s operating assets are financed. In addition, management utilizes the ratio of net borrowings to total shareholders’ equity including non-controlling interest (leverage) to assess Eni’s capital structure, to analyze whether the ratio between finance debt and shareholders’ equity is well balanced according to industry standards and to track management’s short-term and medium-term targets. Management continuously monitors trends in net borrowings and trends in leverage in order to optimize the use of internally-generated funds versus funds from third parties. The measure calculated in accordance with IFRS that is most directly comparable to net borrowings is total debt (short-term and long-term debt). The most directly comparable measure, derived from IFRS reported amounts, to calculate leverage is the ratio of total debt to shareholders’ equity (including non-controlling interest). Eni’s presentation and calculation of net borrowings and leverage may not be comparable to that of other companies.

The tables below set forth the calculations of net borrowings and leverage for the periods indicated and their reconciliation to the most directly comparable GAAP measure.

At the end of 2010, net borrowings amounted to euro 26,119 million, representing a euro 3,064 million increase from 2009. This increase was mainly due to the large amount of capital expenditures made in the year, dividend payment to shareholders executed in the year and pre-payments to the Company’s suppliers of gas under long-term contracts upon triggering the take-or-pay clause. These outflows were only partially funded with cash flows from

operations, divestments for the year and cash inflow from transferring certain account receivables without recourse to factoring institutions, amounting to euro 1,279 million due in 2011. As a result of an increased level of net borrowings, the Group leverage inched higher to 0.47 at December 31, 2010 from 0.46 as of end of 2009. The Group net equity increased due to net profit for the year and currency translation differences recorded in translating to euro amounts net equity of subsidiaries whose functional currency is the U.S. dollar due to the dollar revaluation in exchange rates recorded at year end (up by 7.3% due to the exchange rate recorded on December 31, 2010 at 1 euro = 1.336 US$ compared to 1 euro = 1.441 US$ at December 31, 2009).

Total debt of euro 27,783 million consisted of euro 7,478 million of short-term debt (including the portion of long-term debt due within 12 months equal to euro 963 million) and euro 20,305 million of long-term debt.

Total debt included bonds for euro 13,572 million (including accrued interest and discount on issuance). Bonds maturing in the next 18 months amounted to euro 192 million (including accrued interest and discount). Bonds issued in 2009 amounted to euro 2,614 million (including accrued interest and discount). Total debt was denominated in the following currencies: euro (79%), U.S. dollar (17%), pound sterling (2%) and 2% in other currencies.

At the end of 2009, net borrowings amounted to euro 23,055 million, representing an euro 4,679 million increase from 2008. This increase was mainly due to the large amount of capital expenditures made in the year, the completion of the Distrigas acquisition and dividend payment to shareholders executed in the year. These outflows were only partially funded with cash flows from operations, divestments for the year and capital transactions. Total debt of euro 24,800 million consisted of euro 6,736 million of short-term debt (including the portion of long-term debt due within twelve months equal to euro 3,191 million) and euro 18,064 million of long-term debt.

> Short-term Debt

As of December 31, 2010, short-term debt of euro 7,478 million (including the portion of long-term debt due within twelve months) increased by euro 742 million over 2009. The weighted average interest rate of Eni’s short-term debt was 0.7% and 0.8% for the years ended December 31, 2010 and 2009, respectively.

At December 31, 2010 Eni had undrawn committed and uncommitted borrowing facilities amounting to euro 2,498 million and euro 7,860 million, respectively (euro 2,241 million and euro 9,533 million at December 31, 2009). These facilities bore interest rates reflecting prevailing financing conditions on the marketplace. Charges in unutilized facilities were not significant.

As of December 31, 2009, short-term debt of euro 6,736 million (including the portion of long-term debt due within twelve months) decreased by euro 172 million over 2008. The weighted average interest rate of Eni’s short-term debt was 0.8% and 4.2% for the years ended December 31, 2009 and 2008, respectively.

> Long-term Debt

As of December 31, 2010, long-term debt of euro 20,305 million increased by euro 2,241 million over 2009.

Eni entered into long-term borrowing facilities with the European Investment Bank which were conditioned to the maintenance of certain performance indicators based on Eni’s Consolidated Financial Statements or maintenance of a minimum level of credit rating. As of the balance sheet date, Eni was in compliance with those covenants. According to the agreements, should the Company fail to comply with maintenance of a minimum credit rating, new guarantees would be provided to be agreed upon with the European Investment Bank. At December 31, 2009 and 2010, the amount of short and long-term debt subject to restrictive covenants was euro 1,508 million and euro 1,685 million, respectively.

> Status of Our Libyan Operations

From February 22, 2011, liquids and natural gas production at a number of fields in Libya and supplies through the GreenStream pipeline have been halted as a result of ongoing political instability and conflict in the Country. Facilities have not suffered any damage and such standstills do not affect Eni’s ability to ensure natural gas supplies to its customers. Eni is technically able to resume gas production at or near previous levels once the situation stabilizes. The overall impact of the Libyan political instability and conflict on Eni’s results of operations and cash flows will depend on how long such situation will last as well as on their outcome, which management is currently unable to predict. Eni’s oil and natural gas production as of end March 2011, was flowing at a rate ranging from 70 to 75 KBBL/d, down from the expected level of approximately 280 KBBL/d. Production is continuing to decline. Current production mainly consists of gas that is entirely delivered to local power generation plants. For further discussion on risks and management outlook on the Libyan situation see “Item 3 – Risk Factors – Political Considerations” and “Item 5 – Outlook”.

> Significant Transactions

In 2010, Eni committed to divest its interests in certain international gas pipelines to settle an antitrust proceeding before the European Commission concerning alleged anti-competitive behavior in the natural gas market ascribed to Eni. Eni was not charged with any illicit behavior and consequently no fines or sanctions were imposed. The Commission accepted Eni’s commitments as of September 29, 2010. Currently, procedures for the divestment of Eni’s interests in the German TENP, the Swiss Transitgas and the Austrian TAG gas transport pipelines and relevant carrier companies are progressing. Given the strategic importance of the Austrian TAG pipeline, which transports gas from Russia to Italy, Eni has negotiated a solution with the Commission which calls for the transfer of its stake to an entity controlled by the Italian State. For further details on the matter see "Item 8 – Legal Proceedings".

In January 2011, the Parent Company Eni SpA also on behalf of other Group companies (including in particular Syndial) filed a proposal with the Italian Ministry for the Environment to enter into a global settlement related to nine sites of national interest (Priolo, Napoli Orientale, Brindisi, Pieve Vergonte, Cengio, Crotone, Mantova, Porto Torres and Gela) where the Group companies have started, as guiltless owners of a number of

126

##### Table of Contents

industrial areas, environmental restoration and clean-up activities. The proposal includes a definition of a number of pending proceedings relating to clean-up issues and environmental damage. The framework of the transaction proposal includes: (i) a global environmental transaction as per Article 2 of Law Decree No. 208/2008 (related to the Pieve Vergonte, Cengio, Crotone, Mantova, Porto Torres and Gela sites); (ii) certain environmental framework agreements that have already been signed by relevant administrative bodies and which interested businesses may adhere to (related to the Priolo, Brindisi and Napoli Orientale sites); and (iii) the settlement of a civil lawsuit regarding environmental damage at the Pieve Vergonte site. Briefly, Eni and its subsidiaries through the proposal:

• |  | commit to execute environmental investments amounting to euro 600 million as provided by the 2011-2014 industrial plan in order to achieve higher levels of efficiency and energy sustainability of their plants;
• |  | reaffirm their commitment to carry out a number of projects to clean up and restore proprietary or concession areas in the abovementioned sites with overall expenditures amounting to euro 1,250 million;
• |  | pledge to pay the Ministry for the Environment a contribution in cash amounting to euro 450 million in view of executing clean-up and remediation works in public areas adjacent to Eni and its subsidiaries proprietary areas; and
• |  | transferring free of charge certain proprietary areas to interested public administrations in order to pursue certain local development projects. Such area are yet to be identified.

As a result of the filing of the proposal of global settlement following thorough and extended contacts with the public bodies, Eni took a charge amounting to euro 1,109 million to the environmental provision in its 2010 consolidated accounts, with a net effect on profit for 2010 full year of euro 783 million including the tax impact of the operation. The charge had no effect on the Group’s consolidated net borrowings at period end. In case of finalization of the global transaction, the payment of the accrued amount will be made progressively according to the agreements applicable to each site. A complex administrative procedure is going to start following the presentation of Eni’s proposal to the Ministry. That entity is responsible for drafting a framework transaction which will undergo technical review on the part of all interested administrative bodies including public and local authorities. Finally, the transaction signed by Eni is due to be ratified by the Italian Council of Ministers.

The Company’s Annual General Shareholders Meeting scheduled on April 29 and May 5, 2011, is due to approve the full-year dividend proposal. Eni expects to pay the balance of the dividend for fiscal year 2010 amounting to euro 0.50 per share in May 2011. Total cash out is estimated at euro 1.81 billion.

Outlook

Management expects that the global economic recovery will progressively strengthen across the year 2011. Nonetheless, the 2011 outlook is characterized by a certain degree of uncertainty and volatility also in light of ongoing political instability and conflict in Libya. Eni forecasts an upward trend for Brent crude oil prices supported by healthier global oil demand. For capital budgeting and planning purposes, Eni assumes an average Brent price of 70 $/BBL for the full year 2011. Management expects that the European gas market will remain weak as sluggish demand growth is insufficient to absorb current oversupplies. Refining margins are expected to remain unprofitable due to weak underlying fundamentals and high feedstock costs. Against this backdrop, management expectations about the main trends in the Company’s businesses for 2011 and beyond are disclosed below.

> Exploration & Production

• |  | The outlook for production of liquids and natural gas in 2011 is affected by the potential impacts associated with ongoing Libyan political instability and conflict and how long they will last, which management is currently unable to predict. Following suspension of activities at several of Eni’s producing sites in Libya and the closure of a pipeline transporting gas from Libya to Italy, Eni’s production in Libya as of end of March 2011, was flowing at a rate ranging from 70 to 75 KBOE/d compared to an expected level for 2011 of approximately 280 KBOE/d. Production is continuing to decline. Due to Libyan developments, management expects the Company’s production to decline in 2011 compared to 2010; see "Item 3 – Risk Factors – Risks associated with continuing political instability in North Africa and Middle East". Outside Libya, management expects to drive growth by ramping-up fields started in 2010 mainly in Iraq, and new field start-ups in Australia, Algeria and the USA, partly offset by mature field declines.
|  | According to management’s plans, production growth will strengthen in the coming years as the Company is targeting a production level in excess of 2.05 mmBOE/d by 2014, implying an annual growth rate of more than 3% in the 2011-2014 period under management’s assumptions for oil prices at 70 $/BBL flat in the 2011-2014 period and return of the Libyan production to its normal rate at some point in the future. Oil price assumptions are particularly significant when it comes to assess the Company’s future production

127

##### Table of Contents

|  | performance considering the entitlement mechanism under Eni’s PSAs and similar contractual schemes. For the current year, the Company estimates that production entitlements in its PSAs would decrease on average by approximately 1,000 BBL/d for a $1 increase in oil prices compared to Eni’s assumptions for oil prices at 70 $/BBL. This sensitivity analysis only applies to small deviations from the 70 $/BBL scenario and the impact on Eni’s production may increase more than proportionally as the deviation increases. However, management believes that the sensitivity of production volumes for each U.S. dollar price increase described above broadly continues to apply up to the current oil price environment with Brent prices hovering at around 120 $/BBL as of the date of this filing, based on the Company’s current portfolio of assets. This sensitivity analysis relates to the existing Eni portfolio and might vary in the future. Management estimates that should oil prices hold the level of 100 $/BBL in the next four years covered by our plan, production growth will be reduced to an average rate of 2% in the same period.
|  | Management expects that a number of factors will drive cost increases in Exploration & Production operations over the future years. Those factors include: (i) the growing complexity of development projects, as a number of planned new developments will be executed offshore or in remote/hostile environment; (ii) increasing investing activities that are necessary to support production plateau at existing fields and counteract natural depletion; and (iii) steady trends in costs for purchasing upstream goods and services. Due to those trends, operating costs and depreciation and amortization charges might trend higher in future years.
|  | Management plans to offset those negative factors by leveraging on the Company’s increasing exposure to large fields where it plans to achieve substantial cost economies due to scale of operations. Also management plans to increase the share of operated production in the Company’s portfolio. Project operatorship enables the Company to exercise tighter control over project execution, expenditures and achievement of project milestones and time schedule. In addition, the Company plans to seek cost efficiencies due to greater deployment of proprietary technologies designed to maximize the rate of hydrocarbon recovery from reservoirs and reduce drilling costs as well as continuing operational improvement.

> Gas & Power

• |  | The outlook for natural gas sales gas in 2011 is affected by the potential impacts associated with ongoing Libyan political instability and conflict and how long they will last, which management is currently unable to predict.
|  | The ongoing Libyan situation which has recently forced the Company to halt gas supplies through the GreenStream pipeline may have certain impacts on the Company’s gas operations. In 2010 the GreenStream pipeline carried 9 BCM (50% being Eni’s share) to the European gas market. All such volumes are purchased by the Company’s Gas & Power segment which resells part of the gas to certain Italian’s importers and customers at the Gela entry point to the national transport network, in Sicily. Globally, management expects the longer the duration of the GreenStream disruption, the larger the sales losses of gas. That negative factor will negatively impact the business segment’s result of operations and cash flow. However, the impact on cash flow may be partly offset by the circumstance that the Company is able to replace Libyan supplies with other gas sources from its supply portfolio to continue sales, thus mitigating the risk of incurring the take-or-pay clause on its long-term supply contracts while the Libyan situation continues.
|  | Management expects that profitability and cash flows in the Company’s gas marketing business will be negatively affected by a weak trading environment in 2011. Rising competitive pressures fuelled by ongoing oversupply in the European market will reduce sales opportunities. Unit margins in sales outside Italy are expected to come under pressure due to depressed spot prices at continental hubs which have become the contractual benchmark in selling formulae outside Italy, whereas the cost of gas supplies to the Group remains indexed to oil prices. Therefore, the Company is exposed to the risk of rising oil prices; in addition, replacing Libyan supplies will hurt the Group average cost of supplies as the Libyan gas is more competitive than other sources. Management plans to counteract those negative factors by means of renegotiating the key contractual terms of its long-term gas purchase contracts, including price revision and contractual flexibility. In this way, management will seek to preserve competitiveness of the Company’s cost structure in order to protect unit margins and recover sales volumes. There is no assurance about the final outcome of planned contract renegotiations. Should the outcome fall short of management expectations, we believe that the Company’s future results of operations and cash flow in its gas marketing business will be negatively affected. Difficult market conditions in the European gas sector are expected to continue over the next two to three years. Looking beyond, management plans on the basis that a number of positive trends will rebalance the European market. European gas demand is expected to recover driven by continuing expansion in the use of gas in electricity production; production rates from European fields are projected to decline thus increasing the need for gas import requirements, and LNG oversupplies will be progressively absorbed by continuing growth in other parts of the world and limited new LNG capacity additions in the Atlantic Basin between 2012 and 2014. We also note that spot prices at European hub have recently spiked driven by recent developments in Japan which we believe may influence a rebalancing between demand and supply in the natural gas market. Eni believes that those

> 128

##### Table of Contents

|  | trends will favor a convergence between spot prices of gas and oil-linked gas prices provided by long-term gas purchase contracts. Against this backdrop, management plans to drive volumes growth in the years subsequent to 2011 targeting an average annual rate of increase of 5% in sales in Italy and key European market in the next four years. Volumes growth is expected to be supported by renegotiations of long-term supply contracts which are expected to add price competitiveness to the Company’s portfolio and effective marketing actions whereby the Company intends to regain market share in Italy and increase sales volumes in certain European markets. The Company intends to leverage its multiple presence in key European markets, particularly in France, Benelux and Germany (see "Item 4 – Gas & Power"), and drive sales growth by developing new customized commercial offers. Based on those actions, Eni plans to increase sales in European markets by adding 8 BCM of new volumes by 2014. In Italy, management plans to boost sales and regain market share by leveraging on the overall quality of its offer, including the offer of pricing formulae and services that are designed to best suit the customers’ needs. The Company intends to deploy tailored solutions and customized contracts to retain client in the business segment, and expand its customer base in the retail segment by means of new marketing initiatives, the bundling of a range of valuable services to the commercial offer and wider geographic presence through an integrated network of agencies and stores. Based on those actions, management targets to expand sales volumes in Italy by 12 BCM by 2014.
|  | Based on the above outlined trends and industrial actions, management believes that profitability in the Company’s gas marketing business will return to same level as in 2009 by the end of the plan period. Profitability will be supported also by pursuing cost efficiencies by streamlining business support activities and reducing marketing and general and administrative costs. In addition, the Company intends to capture margins improvements by optimizing the value of its assets (gas supply contracts, customer base, and market position) and a new risk management strategy. Actions that will be implemented as part of that include: (i) effectively managing flexibilities associated with the portfolio of long-term gas supply contracts and other assets available to the Company in the gas value chain, also entering arbitrage contracts so as to unlock value from the Company’s access to storage capacities and transport rights and other assets; (ii) effectively managing the commodity risk and the volume risk by entering contractual positions on the marketplace in order to capture possible favorable trends in market prices, within limits set by internal policies and guidelines that define the maximum tolerable level of market risk. For further information on the market risk and how the Company manages it see "Item 11 – Quantitative and Qualitative Disclosures About Market Risk" and "Item 18 – Note 34 to the Consolidated Financial Statements".
|  | Considering that current imbalances between demand and supply on the European market are expected to continue for some time, management factored in its planning assumptions the risk that the Company may fail to fulfill its contractual obligations associated with the Company’s long-term supply contracts to off-take minimum annual quantities for significant amounts in the next two years. Those projections may be revised in case the Libyan political instability and conflict should continue for a prolonged period of time as lower availability of Libyan gas might eventually diminish the take-or-pay risk. In light of management assumptions for long-term growth in gas demand, the Company believes that in the long-term it will be in the position to recover volumes of gas which have been pre-paid in the years 2009 and 2010 due to the take-or-pay clause and also possibly new pre-paid volumes associated with the contractual clause which might arise due to uncertainties and weak conditions in the gas market over the next two years. For more information see the specific risk paragraph in "Item 3 – Risk Factors". For a discussion of certain risks relating to the impact of the evolution of Italian regulation of the natural gas sector on Eni’s take-or-pay contracts see "Item 3 – Risk Factors – Natural Gas Market".
• |  | Regulated businesses in Italy are planned to benefit from the pre-set, regulatory return on new capital expenditures and cost savings from integrating the whole chain of transport, storage and distribution activities.

> Refining & Marketing

• |  | Refining margins are expected to remain at an unprofitable level in 2011 as weak industry fundamentals are expected to persist in the near future. Specifically, high feedstock costs, weak demand, excess inventory levels and compressed differentials between heavy and light crudes will continue squeezing margins on products. Refining throughputs on Eni’s account for the year 2011 are planned to be in line with 2010 (actual throughputs in 2010 were 34.8 mmtonnes), due to higher volumes processed on more competitive refineries, the optimization of refinery cycles, as well as efficiency actions implemented in response to a volatile trading environment.
|  | Retail sales of refined products in Italy and the rest of Europe are expected to be in line with 2010 (11.73 mmtonnes in 2010) against the backdrop of weaker demand. Management plans to improve sales and profitability leveraging on selective pricing and marketing initiatives, starting new service stations and developing the "non-oil" business.

##### Table of Contents

> Engineering & Construction

• |  | The Engineering & Construction business is expected to see solid results due to a robust order backlog. The segment is expected to leverage its diversified business model articulated across various market sectors combined with a strong competitive position in frontier areas, which are traditionally less exposed to the cyclical nature of this market. The start of operations of new advanced assets in 2010 and 2011 coupled with the size and quality of the backlog and management focus on execution, underpin expectations for a further strengthening of Saipem’s competitive position in the medium-term.

> Petrochemicals

• |  | Management expects that results of the Petrochemical segment will continue to recover as demand for petrochemical products strengthens on the back of a global economic upturn. However, rising oil prices may negatively affect this segment’s results of operations as the Company may be unable to transfer cost increases to final prices of commodities due to competitive pressures. Management plans to implement a number of initiatives designed to reduce fixed operating expenses and to realign the industrial set-up of Eni’s petrochemical operations with a view to enhancing areas of competitive advantage.

> Capital Expenditure plans

Over the next four years, the Company plans to invest euro 53.3 billion in its businesses to support continued organic growth; approximately 73%, 14%, 5.4% and 4.5% of planned capital expenditures is expected be directed to the Exploration & Production, Gas & Power, Refining & Marketing and Engineering & Construction segments, respectively.

The main planned projects are as follows: (i) development of oil and gas reserves mainly in Iraq, Norway, Kazakhstan, Angola, Italy, Congo, Nigeria, Algeria and the USA; (ii) exploration projects to be executed mainly in the USA, Egypt, Angola, Italy, Australia, Nigeria and Norway; (iii) upgrading of national pipelines for transporting natural gas, as well as upgrading of Italian distribution networks and gas storage capacity; (iv) completion of the upgrading and new vessel construction program in the Engineering & Construction segment; (v) refinery upgrading, targeting an increase in conversion capacity mainly by completing the EST project at the Sannazzaro refinery; and (vi) upgrading of Eni’s networks of service stations for marketing petroleum products.

Eni’s capital expenditure program is expected to increase by approximately 1% compared to the previous industrial plan due to planned expenditures for developing new upstream projects, particularly those associated with reserves development in Iraq, and offshore Angola, the circumstance that the Company is forecasting steady trends in costs for materials and sector specific services in its upstream projects and the assumption of the U.S. dollar appreciation against the euro. Lower capital expenditures are associated with the completion of the plan for upgrading the fleet of vessels and offshore rigs of Saipem.

For the year 2011, management plans to make capital expenditures of approximately euro 14 billion which is broadly in line with 2010 (euro 13.87 billion were invested in 2010), and will mainly be directed to developing large fields and starting production at new important fields in the Exploration & Production Division, refinery upgrading related in particular to the realization of the EST project, completing the program of enhancing Saipem’s fleet of vessels and rigs, and upgrading the natural gas transport infrastructure.

Management expects to pursue strict capital discipline when assessing individual capital projects. Management assumed an oil price of 70 $/BBL flat in the next four-year period; longer-term management assumed an oil price of 70 $/BBL that is adjusted to take account of expected inflation from 2015 onwards. The internal rate of return of each project is compared to the relevant hurdle rate, differentiated by business segment and country of operation. These hurdle rates are calculated taking into account: (i) the weighted average cost of capital to the Group. In 2010 management assessed that the cost of capital to the Group decreased by 0.5 percentage points on average from the previous year reflecting a reduced market premium for the equity risk and a slight decrease in the cost of borrowings to Eni following expected trends in the main market benchmarks. Such trends were partially offset by increased market yields on assets risk-free due to a higher risk premium for Italy; (ii) a country risk premium which reflects the specific level of risk associated with each country of operations in terms of macroeconomic, business and socio-political current conditions and outlook; and (iii) a premium for the business risk.

> Liquidity and leverage

In the foreseeable future, management is strongly focused on preserving a solid balance sheet and an adequate level of liquidity taking into account macroeconomic uncertainties and tight financial markets. For planning purposes, management calculated the Company’s expected cash flows assuming a scenario of Brent prices at 70 $/BBL for the years 2011-2014 to assess the financial compatibility of its capital expenditures programs and dividend policy with internal targets of ratio of total equity to net borrowing. We note that Brent price in the period January 1 to March 31, 2011 was 104.97 $/BBL on average and it was 118.62 $/BBL as of April 1, 2011. Management plans for achieving a reduction in the ratio of net borrowings to total equity ("leverage") in 2011 compared to end of the year 2010 also taking into account the planned divestment of assets for an amount of euro 2 billion. Looking forward, management intends to seek to progressively reduce this ratio to below 40% by the end of the plan period leveraging on future cash flow from operations.

For planning purposes, management assumed an average exchange rate of approximately 1.30 U.S. dollars per euro in the 2011-2014 period. Given the sensitivity of Eni’s results of operations to movements in the euro versus the U.S. dollar exchange rate, trends in the currency market represent a factor of risk and uncertainty. See "Item 3 – Risk Factors".

> Dividend policy

In the next four-year period management intends to pursue a progressive dividend policy. Management plans to pay euro 1.00 a share dividend for 2010 subject to approval from the General Shareholders’ Meeting scheduled on May 5, 2011. Of this, euro 0.50 per share was paid in September 2010 as an interim dividend with the balance of euro 0.50 per share expected to be paid late in May 2011. For the year 2011, management plans to start growing the dividend in line with OECD inflation. This dividend policy is based on management’s planning assumptions for oil prices at 70 $/BBL flat in the 2011-2014 period. If management assumptions on oil prices were to change, management may revise the dividend and reset the basis for progressive dividend increases. In future years, management expects to continue paying interim dividends for each fiscal year, with the balance for the full-year dividend paid in the following year.

The expectations described above are subject to risks, uncertainties and assumptions associated with the oil and gas industry, and economic, monetary and political developments in Italy and globally that are difficult to predict. There are a number of factors that could cause actual results and developments to differ materially, including, but not limited to, political instability in Libya and other countries, crude oil and natural gas prices; demand for oil and gas in Italy and other markets; developments in electricity generation; price fluctuations; drilling and production results; refining margins and marketing margins; currency exchange rates; general economic conditions; political and economic policies and climates in countries and regions where Eni operates; regulatory developments; the risk of doing business in developing countries; governmental approvals; global political events and actions, including war, terrorism and sanctions; project delays; material differences from reserves estimates; inability to find and develop reserves; technological development; technical difficulties; market competition; the actions of field partners, including the inability of joint venture partners to fund their share of operating or developments activities; industrial actions by workers; environmental risks, including adverse weather and natural disasters; and other changes to business conditions. Please refer to "Item 3 – Risk Factors".

> Off-Balance Sheet Arrangements

Eni has entered into certain off-balance sheet arrangements, including guarantees, commitments and risks, as described in Note 34 to the Consolidated Financial Statements. Eni’s principal contractual obligations, including commitments under take-or-pay or ship-or-pay contracts in the gas business, are described under "Contractual Obligations" below. See the Glossary for a definition of take-or-pay or ship-or-pay clauses.

Off-balance sheet arrangements comprise those arrangements that may potentially impact Eni’s liquidity, capital resources and results of operations, even though such arrangements are not recorded as liabilities under generally accepted accounting principles. Although off-balance sheet arrangements serve a variety of Eni’s business purposes, Eni is not dependent on these arrangements to maintain its liquidity and capital resources; nor is management aware of any circumstances that are reasonably likely to cause the off-balance sheet arrangements to have a material adverse effect on the company’s financial condition, results of operations, liquidity or capital resources.

Eni has provided various forms of guarantees on behalf of unconsolidated subsidiaries and affiliated companies, mainly relating to guarantees for loans, lines of credit and performance under contracts. In addition, Eni

131

has provided guarantees on the behalf of consolidated companies, primarily relating to performance under contracts. These arrangements are described in Note 34 to the Consolidated Financial Statements.

> Liquidity Risk

Liquidity risk is the risk that suitable sources of funding for the Group may not be available, or the Group is unable to sell its assets on the marketplace as to be unable to meet short-term finance requirements and to settle obligations. Such a situation would negatively impact Group results as it would result in the Company incurring higher borrowing expenses to meet its obligations or under the worst of conditions the inability of the Company to continue as a going concern. 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. For a description of how the Company manages the liquidity risk see "Item 18 – Note 34 to the Consolidated Financial Statements".

At December 31, 2010, Eni maintained short-term committed and uncommitted unused borrowing facilities of euro 10,358 million, of which euro 2,498 million were committed, and long-term committed unused borrowing facilities of euro 4,901 million. These facilities were under interest rates that reflected market conditions. Fees charged for unused facilities were not significant. Eni has in place a program for the issuance of Euro Medium Term Notes up to euro 15 billion, of which about euro 10.4 million were drawn as of December 31, 2010.

The Group has debt ratings of A+ and A-1 respectively for long (outlook stable) and short-term debt assigned by Standard & Poor’s and Aa3 and P-1 (outlook stable) assigned by Moody’s.

A security rating is not a recommendation to buy, sell or hold securities. A security rating may be subject to revision or withdrawal at any time by the assigning rating organization. Each rating should be evaluated independently of any other rating.

> Working Capital

Management believes that, taking into account unutilized credit facilities, Eni’s credit rating and access to capital markets, Eni has sufficient working capital for its foreseeable requirements.

> Credit Risk

Credit risk is the potential exposure of the Group to losses in case counterparties fail to perform or pay amounts due. For a description of how the Company manages the Credit risk see "Item 18 – Note 34 to the Consolidated Financial Statements". For information about credit losses in 2010 and the allowance for doubtful accounts see "Item 18 – Note 9 to the Consolidated Financial Statements".

> Market Risk

In the normal course of its operations, Eni is exposed to market risks deriving from fluctuations in commodity prices and changes in the euro versus other currencies exchange rates, particularly the U.S. dollar, and in interest rates. For a description of how the Company manages the Market risk see "Item 18 – Note 34 to the Consolidated Financial Statements".

CHAIRMAN
The compensation of the Chairman of the Board of Directors has been resolved by Eni’s Shareholders’ Meeting and includes:

(a) |  | a base salary of euro 265,000 and reimbursement of out of pocket expenses; and
(b) |  | a bonus which amount 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, taking account of the dividend paid. This bonus will amount to euro 80,000 or euro 40,000, 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 2009, Eni rated fifth and consequently no bonus was paid in 2010.

With regard to the powers delegated to the Chairman, the Board of Directors determined further compensation, as follows:

(a) |  | an annual emolument of euro 500,000; and
(b) |  | an annual performance bonus based on the achievements of the Company’s target determined in the same way as for the CEO (see below). In 2010, based on 2009 Eni’s results, a bonus equal to 112% of the target level was determined, within an interval ranging from 85% to 130% of said target level. The target level of the bonus is 60% of the annual emolument. In 2010, this bonus amounted to euro 336,000, corresponding to 67% of the annual emolument.

Compensation of the Chairman also includes an insurance against death or permanent inability caused by injury or sickness in the exercise of his duties or under certain other circumstances as stipulated collectively for all managers of Italian companies producing goods and services. In particular, a specific insurance policy has been underwritten which guarantees euro 500,000 to survivors.

CEO
Compensation for the CEO has been resolved by the Board of Directors of Eni in connection with his position both as CEO and as General Manager of the parent company Eni SpA.

As General Manager of Eni SpA, his terms of employment are regulated by the "Contratto collettivo nazionale di lavoro per i dirigenti di aziende produttrici di beni e servizi" (the Italian national collective contract for managers of companies producing goods and services), as well as by any internal agreement stipulated by the representatives of managers and Eni SpA.

The CEO compensation includes the following items:

(a) |  | an annual fixed amount of euro 1,430,000, including a base salary of euro 1,000,000 for the services as General Manager and an emolument of euro 430,000 for the services as CEO;
(b) |  | an annual performance bonus based on the achievement of the Company targets. These targets are 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. In 2009, said targets included financial performance (with a 30% weight), divisional operating performance (30%), a set level of adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) (30% weight) and reduction of Company’s costs (10%). 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. The target and maximum amount of this bonus corresponds respectively to 110% and 155% of the fixed amount under a) above. In 2010, based on 2009 Eni’s results, a bonus equal to 112% of the target level was determined, within an interval ranging from 85% to 130% and a bonus of euro 1,830,000 was paid;
(c) |  | a long-term incentive under the incentive scheme as approved by the Board of Directors on March 25, 2009 as proposed by the Compensation Committee. This incentive scheme provides a deferred monetary incentive with a target level corresponding to 55% of the fixed amount under a) above. The bonus will vest over the next three years upon achievement of certain preset Company annual targets in terms of EBITDA for the reference three-year period. Vested amounts will range from 0 to 170% of the award. The 2010 bonus that was awarded to the CEO amounted to euro 786,500;
(d) |  | taking into account that on the same occasion, the Board of Directors decided to discontinue the stock option plan, based on the resolution of the Compensation Committee, and in force of the contractual obligation to the CEO of adopting an alternative incentive scheme with same economic effects, in order to replace and compensate for the discontinued stock option incentive the CEO was awarded a further deferred monetary bonus whose value and characteristics are comparable with those of the former plan. This bonus will vest over the next three years upon achievement of certain performance targets in terms of variation of the Adjusted Net Profit + DD&A (Depletion Depreciation & Amortization) as compared to that of the other six largest international oil companies for market capitalization for the reference three-year period. The 2010 bonus that was awarded to the CEO amounted to euro 2,500,960 and will be paid in 2013 according to a percentage ranging from 0 to 130% of the awarded amount in relation to the performance achieved in the reference three-year period. In 2010, the 2007 long-term incentive scheme approved in the same year by the Board of Directors as proposed by the Compensation Committee vested.

##### Table of Contents

|  | This incentive scheme provided: (i) a deferred monetary incentive, linked to the achievement of certain Company’s financial performance annual targets in terms of EBITDA; and (ii) a stock option awards which vested upon achievement of certain performance targets of the Eni share measured in terms of Total Shareholder Return (TSR) that considers both the stock appreciation and the dividend, as compared to that achieved by the other six largest international oil companies for market capitalization over the three-year vesting period. Under this scheme, based on results achieved in the 2007-2009 three-year period, the CEO received:

|  | (i) |  | an amount equal to 143% of the deferred monetary incentive that was granted in 2007 with a target level corresponding to 55% of the fixed amount under a) above. In 2007, this award was accrued for euro 1,125,000; and
|  | (ii) |  | an award of stock options corresponding to 42% of options granted in 2007 (573,000 rights with a strike price of euro 27.451 per share corresponding to the arithmetic average of official prices registered on the Mercato Telematico Azionario in the month preceding the grant);

(e) |  | severance payments as regulated by Italian laws, which consist of a lump sum to be paid to the employee upon retirement. To this end, the Company recognizes yearly accruals computed by dividing the total remuneration earned as General Manager (base salary, bonuses and stock compensation) by 13.5. The amounts accrued are revaluated yearly at a fixed rate of 1.5% plus the 75% of the yearly official consumer price index increase;
(f) |  | as an integration to the severance payment described above, should the employment contract of Mr. Scaroni as General Manager of Eni SpA be terminated upon expiry of the term of his office as CEO or upon earlier termination of such office, he will be entitled to receive a payment of euro 3,200,000 plus an amount corresponding to the average performance bonus earned in the three-year period 2008-2010, in lieu of notice thus waiving both parties from any obligation related to notice. This amount will not be paid if the termination of office meets the requirement of due cause as per Article 2119 of the Italian Civil Code, in case of death and in case of resignation from office other than as the result of a reduction in the powers currently attributed to the CEO. Furthermore, upon expiry of the contract as employee of Eni, the CEO in his capacity as General Manager of the parent company is entitled to receive an indemnity that is accrued along the service period by taking into account social security contribution rates and post-retirement benefit computations applied to the CEO annual emolument and 50% of the maximum bonuses earned as a Director. A provision of euro 252,519.90 was accrued in 2010;
(g) |  | competition clause: the CEO agrees not to be engaged, on his own account and directly, in any business that may be in competition with the businesses of Eni, as per its By-laws, in Italy, Europe and North America for a year after termination of office. Based on this arrangement, Eni will pay a fee corresponding to euro 2,219,000. As a consequence of any breach of this clause, the CEO would lose the right to such fee and reimburse any amount already paid, and shall pay to Eni damages in an amount agreed among the parties to correspond to twice such non-competition fee;
(h) |  | the pension scheme corresponds to the scheme applied to Eni managers and provided by INPS (the Italian state social security entity) to all Italian workers. In addition, the CEO is included in an additional pension scheme under the form of an Eni Group pension fund agreed collectively by Eni and Eni managers which provides integration, in the form of a lump sum payment or perpetuity, to the pension paid by the State. This integration is proportional to contributions to the fund made by both the manager and the Company in equal amounts. The integration is awarded to the manager when eligible for the payment of the pension from the State, provided that a minimum time period has elapsed according to the Fund By-laws. An agreement signed on November 9, 2009, established that the Company’s and the manager’s payment to this fund amounts to 4% (that could be increased up to 4.5%) of total emoluments earned by the CEO in his position as General Manager (i.e. the aggregate of the annual salary and bonuses up to a maximum of euro 200,000);
(i) |  | like all other Eni managers, Mr. Scaroni is entitled to participate in a health insurance fund financed by Eni managers and Eni which provides reimbursement of certain medical expenses on the basis of rules and parameters as provided by the Fund’s By-laws; and
(j) |  | insurance against death or permanent inability caused by injury or disease in the exercise of his duties or under certain other circumstances as stipulated collectively for all managers of Italian manufacturing companies. In particular a specific insurance policy has been underwritten on behalf of Mr. Scaroni which guarantees euro 7.5 million to beneficiaries in case of death or disability, however determined.

MEMBERS OF THE BOARD OF DIRECTORS
The compensation of members of the Board of Directors has been determined by Eni’s Shareholders’ Meeting and includes:

(a) |  | an annual emolument of euro 115,000 and reimbursement of out of pocket expenses; and
(b) |  | a bonus determined in accordance with the performance of the Eni share in the reference year as compared with the performance of the seven largest international oil companies for market capitalization, taking account of the dividend paid. This bonus will amount to euro 20,000 or euro 10,000 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 2009, Eni rated fifth and consequently no bonus was paid in 2010.

The Board of Directors in the meeting of June 11, 2008, reasserting its previous decision of 2006, as proposed by the Compensation Committee and advised by the Board of Statutory Auditors, confirmed the 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.

> Long-term Monetary Incentive

Eni’s Board of Directors approved a new long-term monetary incentive scheme addressed to critical managerial resources in order to support achievement of better returns than those of the Company’s main competitors over the long-term. Managers involved in this scheme are in positions which are directly linked to the Company’ results or are otherwise of strategic interest to the Company. The scheme was intended to replace a stock-based compensation plan that was discontinued in 2009.

This plan provides for award of a base incentive to be paid after a vesting period of three years. The amount that will be actually paid is a percentage ranging from 0 to 130% of the base amount, and is subject to achievement of a performance parameter represented by a measure of Adjusted Net Profit + Depletion, Depreciation & Amortization (DD&A) recorded in the 2010-2012 three-year period as benchmarked to the performance achieved by a panel of the largest international oil companies by market capitalization. The recipient or his/her heirs will preserve the right to participate in this scheme in definite measure with reference to the time period which elapses between grant and the possible occurrence of any of the following events: (i) termination of the employment contract by mutual consent; (ii) death of the recipient; (iii) loss of control by Eni SpA of the subsidiary where the recipient is employed; and (iv) divestment to a non-controlled entity of the subsidiary or the business where the recipient is employed. In case of unilateral termination of the employment contract, the right to the incentive expires. A similar scheme was approved for the CEO and General Manager. In case of termination of his employment contract before the end of the vesting period, the incentive will still be paid when it vests on the basis of the assessment of the performance achieved in the reference three-year period. The following table sets out the bonuses awarded in 2010 to the CEO, the Chief Operating Officers of Eni’s Divisions, and the total amount awarded to the Company’s managers with strategic responsibilities.

Board Practices

> Corporate Governance

The corporate governance structure of Eni SpA follows the Italian traditional model, which assigns corporate management to the Board of Directors, the core of the organizational system, supervisory functions to the Board of Statutory Auditors and auditing of the accounts to the audit firm appointed by the Shareholders’ Meeting.

The names of Eni’s Directors, their positions, the year when each of them was initially appointed as a Director and their ages are reported in the related table above.

The Board of Directors will expire at the date of the Shareholders’ Meeting approving Eni’s 2010 financial statements.

> Board of Directors’ duties and responsibilities

The Board of Directors has the widest powers for the ordinary and extraordinary administration of the Company in relation to its purpose. In a resolution dated June 11, 2008, the Board appointed Paolo Scaroni as CEO and General Manager entrusting him with the widest powers for the ordinary and extraordinary administration of the Company, while exclusively reserving the most important strategic, operational and organizational powers in addition to those that cannot be delegated by law.

In particular, performing the powers as specified in the Eni Code, and in consultation with the relevant committees, the CEO, and/or the Chairman where applicable, the Board, among other tasks: defines the system of corporate governance of the Company and the Group; establishes the internal committees of the Board; assigns and revokes proxies to the CEO and to the Chairman and defines the limits and modalities for exercising such proxies; defines the fundamental guidelines pertaining to the organizational, administrative and accounting structure of the Company and the internal control system; examines and approves the Company and Group’s strategic, industrial and financial plans and agreements, annual budgets and the semi-annual financial report and the interim reports, as well as the Sustainability Report; receives information from Directors with proxies relative to activities implemented during the exercising of proxies and receives periodical half-year information from the internal committees of the Board; assesses the general management trends of the Company and of the Group paying particular attention to conflicts of interest; examines and approves the operations of the Company and its subsidiaries which are significant from a strategic, economic and financial perspective, particularly with regards to situations in which one or more Directors retain personal or third party interests as well as related parties transactions9; appoints and dismisses the Chief Operating Officer, the Officer in charge of preparing financial reports, the Officer in charge of internal control and a Senior Executive Vice President of Internal Audit; defines remuneration criteria for top management of the Company and the Group; resolves on the exercise of voting rights and on the appointment of members of corporate bodies of the primary subsidiaries; formulates the proposals to present to the Shareholders’ Meeting; and examines and resolves on other issues which Directors with proxies believe it is appropriate to present to the Board due to their particular relevance or sensitivity.

> Directors’ independence

The Board of Directors has confirmed that the non-executive Directors Clô, Colombo, Marchioni, Reboa, Resca, Scibetta and Taranto are independent. This determination was made by the Board at its meeting on March 10, 2011 on the basis of statements made and information available to the Company, and taking into account the criteria of independence set forth in Italian regulation and the Corporate Governance Code of Borsa Italiana. Director Clô was confirmed as being independent under the terms of the Eni Code as well, even though he has held the position

for over nine years, because he was appointed by the minority shareholders (specifically the institutional investors) and because of his recognized professional skills and independence of judgment.

The Board of Statutory Auditors has consistently verified, at its meeting on March 10, 2011, the correct application of the criteria and procedures adopted by the Board for assessing the independence of its members. The above-referenced independence criteria may not be equivalent to the independence criteria set forth by the NYSE listing standards applicable to a U.S. domestic company.

> Board Committees

The Board of Directors has established three internal committees with consulting and advisory functions: (a) the Internal Control Committee; (b) the Compensation Committee; and (c) the Oil-Gas Energy Committee. The Internal Control Committee and the Compensation Committee are required by the Corporate Governance Code of Borsa Italiana. The composition, role and functioning of these committees are governed by their relative regulations which are approved by the Board, in compliance with the criteria outlined in the Eni Code.

The committees required by the Code (Internal Control Committee and Compensation Committee) are composed of not less than three members and, in any case, fewer than the majority of members of the Board. The committees are currently composed of non-executive Directors, all of whom are independent.

In performing their functions, the committees retain the right to access any information and Company departments that are necessary to carry out their tasks. They are also provided with adequate financial resources and retain the right to avail themselves of external consultants according to terms established by the Board of Directors. The Chairman of the Board of Statutory Auditors or a Statutory Auditor appointed by him may participate in Committee meetings. Non-members may also participate in committee meetings upon explicit invitation and with reference to specific topics on the agenda of the day. Minutes of all committee meetings are drafted by the respective secretaries. Committees’ meetings are summarized by the respective secretaries. The current members of the committees have been appointed at a meeting of the Board of Directors held on June 11, 2008.

> Compensation Committee

Members: Mario Resca (Chairman), Francesco Taranto, Alberto Clô and Paolo Andrea Colombo.

Established by the Board of Directors in 1996, this committee advises Board of Directors regarding the remuneration payable to Directors with proxies and to the members of the Board’s committees and, on instructions from the CEO, regarding: (i) annual and long-term incentive plans; (ii) general criteria for the remuneration of executives with strategic responsibilities; and (iii) objectives and results of the Performance and Incentive Plans. It performs the tasks assigned by the Management System Guideline on "Transactions involving interests of Directors and Statutory Auditors and transactions with related parties", adopted in November 2010 by the Board of Directors pursuant to Consob regulation of March 12, 2010.

During 2010, the Compensation Committee met six times, with a 100% attendance rate, and made proposals regarding: (i) Eni’s 2009 results and 2010 objectives for the purposes of the Annual and Long-Term Incentive Plans; (ii) the variable remuneration of the Chairman, CEO and Directors based on the results achieved in 2009; (iii) the criteria of the remuneration policy for executives with strategic responsibilities; (iv) establishment of the 2010 Long-Term Monetary Incentive Plan for the CEO, to replace and compensate for the Eni Stock Option Plan; (v) implementation of the 2010 Long-Term Monetary Incentive Plan, to replace the Stock Option Plan, for critical managerial resources; and (vi) 2010 implementation of the Deferred Monetary Incentive Plan and its assignment to the CEO.

> Eni Watch Structure and Model 231

According to the Italian regulations pertaining to the "administrative liability of legal entities deriving from offences", pursuant to Legislative Decree No. 231 of June 8, 2001 (hereinafter, "Legislative Decree No. 231 of 2001"), associations, including corporations, may be held liable – and therefore charged with the payment of a penalty or placed under injuction, with regard to certain offences that are attempted or committed in Italy or abroad in the interest or for the benefit of the Company. The companies may, in any case, adopt organizational, management and control models suitable to the prevention of possible offences. With regards to this issue, Eni SpA’s Board of Directors – in its meetings of December 15, 2003 and January 28, 2004 – has approved an organizational, managerial and control model pursuant to Legislative Decree No. 231 of 2001 ("Model 231") and has appointed the Eni Watch Structure11. The composition of the Eni Watch Structure, initially consisting of only three members, was amended in 2007 with the addition of two external members, one of them appointed Chairman of the Eni Watch Structure and selected from among university professors and professionals of proven experience and expertise in economics and business management. The internal members are represented by the Senior Executive Vice President of Legal Affairs, the Executive Vice President of Human Resources and Organization and the Senior Executive Vice President of Internal Audit Department of the Company (or their direct reports).

> Audit firm

The auditing of the Company’s accounts is entrusted, as per current legislation, to an independent audit firm whose appointment falls under the competency of the Shareholders’ Meeting, upon the Board of Statutory Auditors opinion.

In addition to the obligations set forth in national auditing regulations, Eni’s listing on the New York Stock Exchange requires that the Audit firm issues a report on the Annual Report on Form 20-F, in compliance with the auditing principles generally accepted in the USA. Moreover, the Audit firm is required to issue an opinion on the efficacy of the internal control system applied to financial reporting.

For the most part, the subsidiaries’ financial statements are subject to auditing by Eni’s Audit firm. Moreover, Eni’s Audit firm, for the purpose of issuing an opinion on the consolidated financial statements, assumes the responsibility for the auditing activities performed by other audit firms with respect to subsidiaries’ financial statements, which represent altogether an irrelevant part of the company’s assets and consolidated turnover.

Upon the Board of Statutory Auditors’ opinion, the Shareholders’ Meeting of April 29, 2010 appointed Reconta Ernst & Young SpA for the financial years 2010-2018.

(a) | i | Cassa Depositi e Prestiti is an entity controlled by the same Ministry.
| i | With Decree of the Ministry of Economy and Finance of November 30, 2010, published in the Official Gazette No. 293 of December 16, 2010, a share trade in has been decided which entails, among other things, the transfer to Cassa Depositi e Prestiti SpA a total of 655,891,140 Eni’s ordinary shares held by the Ministry of Economy and Finance. According to said Decree, the transfer of shares has been finalized on December 21, 2010.

In the ordinary course of its business, Eni enters into transactions concerning the exchange of goods, provision of services and financing with non-consolidated subsidiaries and affiliates as well as other companies owned or controlled by the Italian Government.

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 42 to the Consolidated Financial Statements.

Item 8. FINANCIAL INFORMATION

Consolidated Statements and Other Financial Information

See "Item 18 – Financial Statements".

> Legal Proceedings

Eni is a party to a number of civil actions and administrative arbitral and other judicial proceedings arising in the ordinary course of business. Based on information available to date, and taking into account the existing risk provisions, Eni believes that the foregoing will not have an adverse effect on Eni’s Consolidated Financial Statements.

For a description of legal proceedings in which Eni is involved and which may affect Eni’s financial position and results of operations see Note 34 to the Consolidated Financial Statements.

> Dividends

Eni’s dividend policy in future periods, and the sustainability of the current amount of dividends over the next four-year period, will depend upon a number of factors including future levels of profitability and cash flow provided by operating activities, a sound balance sheet structure, capital expenditures and development plans, in light of the "Risk Factors" set out in Item 3. The parent Company’s net profit and, therefore, the amounts of earnings available for the payment of dividends will also depend on the level of dividends received from Eni’s subsidiaries. However, subject to such factors, under the Company’s scenario for Brent prices at 70 $/BBL flat over the next four years, management plans to grow the dividend in line with OECD inflation from 2011. If management assumptions on oil prices were to change, management may revise the dividend and reset the basis for progressive dividend increases.

Management intends to propose to the Annual Shareholders’ Meeting scheduled on May 5, 2011, the distribution of a dividend of euro 1.00 per share for fiscal year 2010, of which euro 0.50 was already paid as interim dividend in September 2010. Total cash outlay for the 2010 dividend is expected at approximately euro 3.6 billion (including the euro 1.8 billion already paid in September 2010) in case the Annual Shareholders’ Meeting approves the annual dividend. In future years, management expects to continue paying interim dividends for each fiscal year, with the balance to the full-year dividend to be paid in each following year.

JPMorgan Chase Bank NA (the "Depositary") functions as depositary bank issuing ADRs pursuant to a deposit agreement (the "Deposit Agreement") among Eni, the Depositary and the beneficial owners ("Beneficial Owners") and registered holders from time to time of ADRs issued hereunder.

As of March 21, 2011 there were 35,091,381 ADRs outstanding, representing 70,182,762 ordinary shares or approximately 2% of all Eni’s shares outstanding, held by 115 holders of record (including the Depository Trust Company) in the United States of America, 113 of which are U.S. residents. Since certain of such ADRs are held by nominees, the number of holders may not be representative of the number of Beneficial Owners in the USA or elsewhere.

The Shares are included in the FTSE MIB Index (the "FTSE MIB"), the primary benchmark index for the Italian stock market. Capturing approximately 80% of the domestic market capitalization, the FTSE MIB measures the performance of 40 highly liquid, leading companies across leading industries listed on MTA and seeks to replicate the broad sector weights of the Italian stock market. The constituents of the FTSE MIB are selected according to the following criteria: sector representation, market capitalization of free-float shares and liquidity. The FTSE MIB is market cap-weighted after adjusting constituents for float. Since June 1, 2009 the FTSE MIB (previously S&P/MIB Index) is the principal indicator used to track the performance of the Italian stock market and is the basis for future and option contracts traded in the Italian Derivatives Market ("IDEM") managed by Borsa Italiana. The Shares are the first largest component of the FTSE MIB, with a weighting of approximately 15.1%, as established by FTSE after the quarterly rebalancing for FTSE MIB effective March 21, 2011.

Trading in the MTA is allowed in any quantity of the Shares as well as other financial instruments. Where necessary, Borsa Italiana may specify a minimum lot for each financial instrument. Since March 28, 2000, a three-day rolling cash settlement has been applied to all trades of equity securities in Italy, instead of the previous five-day settlement. In addition, future and option contracts on the Shares are traded on IDEM and securitized derivatives based on the Shares are traded on the Italian Securitized Derivatives Market ("SeDeX"). IDEM facilitates the

155

##### Table of Contents

trading of future and option contracts on index and shares issued by companies that meet certain required capitalization and liquidity thresholds. SeDeX is the Borsa Italiana electronic regulated market where it is possible to trade securitized derivatives (covered warrants and certificates).

Borsa Italiana disseminates daily market data and news for each listed security, including volume traded and high and low prices. At the end of each trading day an "official price", calculated as the weighted average price of the total volume of each security traded in the market during the session, and a "reference price", calculated as the closing-auction price, are reported by Borsa Italiana. For the purposes of the automatic control of the regularity of trading on MTA, the following price variation limits shall apply to contracts concluded on shares making up the FTSE MIB, effective December 20, 2010: (i) ± 5.0% (or such other amount established by Borsa Italiana in the "Guide to the Parameters" for trading on the regulated markets organized and managed by Borsa Italiana) with respect to the static price (the static price shall be the previous day’s reference price, in the opening auction, or the auction price, in the continuous trading phase); and (ii) ± 3.5% (or such other amount established by Borsa Italiana in the "Guide to the Parameters") with respect to the dynamic price (the price of the last contract concluded during the continuous trading phase). Where the price of a contract that is being concluded exceeds one of the price variation limits referred to above, trading in that security will be automatically suspended and a volatility auction phase begun for a certain period of time.

Markets

The Commissione Nazionale per le Società e la Borsa (the National Commission for Companies and the Stock Exchange or "Consob"), is the public authority responsible for regulating and supervising the Italian securities markets to ensure the transparency and regularity of the dealings and protect the investing public. Borsa Italiana, which is part of London Stock Exchange Group, following the merger effective October 1, 2007, is a joint stock company authorized by Consob to operate regulated markets in Italy; it is responsible for the organization and management of the Italian stock exchange. One of the fundamental characteristics of the financial market organization in Italy is the separation of responsibility for supervision (Consob and the Bank of Italy) from that of market management (Borsa Italiana). Main responsibilities of Borsa Italiana are the admission, exclusion and suspension of financial instruments and intermediaries to and from trading and the surveillance of the markets.

According to Consob Regulations, Borsa Italiana has issued rules governing the organization and management of the Italian Regulated Markets it is responsible for, which are MTA (shares, convertible bonds, pre-emptive rights, warrants and Funds), TAH (After Hours trading market), ETFplus (Exchange Traded Funds and Exchange Traded Commodities market), IDEM (index and stock derivatives market), SeDeX (covered warrants and certificates), MOT (bond market) and MIV (Investment Vehicles Market), as well as the admission to listing on and trading on these markets.

According to EU Markets in Financial Instruments Directive (2004/39/EC) ("MiFID") and Consob Regulations, orders can be routed not only to Regulated Markets but also to either Multilateral Trading Facilities ("MTF"s) or Systematic Internalisers. A MTF is a multilateral system, operated by an investment firm or a market operator, which brings together multiple third-party buying and selling interests in financial instruments – in the system and in accordance with non-discretionary rules – in a way that results in a contract. A Systematic Internaliser is an investment firm or a bank which deals on own account by executing client orders outside a Regulated Market or a MTF. Outside Regulated Markets, block trading is also permitted for orders that meet certain minimum size requirements and must be notified to Consob and Borsa Italiana.

According to Legislative Decree No. 58 of February 24, 1998 ("Decree No. 58"), the Consolidated Law on Financial Intermediation, the provision of investment services and activities to the public on a professional basis is reserved to banks and investment firms ("authorized persons"). The Bank of Italy and Consob shall exercise supervisory powers over authorized persons. They shall each supervise the observance of regulatory and legislative provisions according to their respective responsibilities. In particular, in connection with the pursuance of the safeguarding of faith in the financial system, the protection of investors, the stability and correct operation of the financial system, the competitiveness of the financial system and the observance of financial provisions, the Bank of Italy shall be responsible for risk containment, asset stability and the sound and prudent management of intermediaries whilst Consob shall be responsible for the transparency and correctness of conduct.

The Bank of Italy, in agreement with Consob, also regulates the operation of the clearing and settlement service for transactions involving financial instruments. The regulations and measures of general application adopted by Consob and the Bank of Italy are available on the website of Consob (www.consob.it) or Bank of Italy (www.bancaditalia.it). The regulations adopted by Borsa Italiana are available on its website (www.borsaitaliana.it).

The registered head office of the Company is located in Rome, Italy, and the Company has two secondary registered offices in San Donato Milanese (Milan).

The full text of Eni’s By-laws is attached as an exhibit to this annual report (last amended on June 3, 2010). See "Exhibit 1".

> Company objects and purpose

According to Article 4 of Eni’s By-laws, Company’s objects include: management of activities in the field of hydrocarbons and natural vapors, all in respect of concessions provided by the law; management of activities in the field of chemicals, nuclear fuels, geothermal, renewable energy sources and energy in general, industrial plant construction and engineering, mining, metallurgy, textile machinery, water derivation, purification and distribution, environmental protection and treatment and disposal of waste, as well as in any other business activity that is instrumental, supplemental or complementary with the aforementioned activities. The Company manages the technical and financial co-ordination of subsidiaries and affiliated companies. Moreover, the Company may take shareholdings and interests in other companies or business with similar purposes, comparable or complementary to its own or those of its subsidiaries or affiliates, either in Italy or abroad, and it may provide collateral and/or personal guarantees for both its own and third-party commitments.

> Directors’ issues

The Eni’s Board of Directors is invested with the fullest powers for ordinary and extraordinary management of the Company and, in particular, the Board has the power to perform all acts it deems advisable for the implementation and achievement of the Company purpose, except for the acts that the law or Eni’s By-laws reserve to the Shareholders’ Meeting.

If the Shareholders’ Meeting has not appointed a Chairman of the Board, the Board shall elect one among its members.

The Board of Directors appoints a Chief Executive Officer and delegates to him all necessary powers for the management of the Company, with the exception of those powers that cannot be delegated in accordance with current legislation and those retained exclusively by the Board of Directors on the matters regarding major strategic, operational and organizational decisions.

According to Eni’s By-laws, the Board of Directors may delegate powers to the Chairman for researching and promoting integrated projects and international agreements of strategic significance.

The Board of Directors may at any time withdraw the powers delegated hereon, proceeding, in the case of revocation of the powers delegated to the Chief Executive Officer, to simultaneously appoint another Chief Executive Officer. The Board of Directors, upon proposal of the Chairman and in agreement with the Chief Executive Officer, may delegate powers for single acts or classes of acts to other among its members.

According with Eni’s By-laws, the quorum for meeting of the Board shall be the majority of the Directors in office who are entitled to vote. Resolutions shall be adopted by an absolute majority of the Directors present who are entitled to vote; in case of a tie, the vote of the person chairing the meeting shall be decisive.

> Interests in Company’s transactions

As provided by Italian Civil Code, when a Director retains a personal interest or an interest on behalf of third parties in Company’s transactions, he shall disclose it to the Board of Directors, specifying the nature, terms, origin and extent of such interest. Based on this provision and in compliance with Consob Regulation on March 12, 2010, and taking also into account recommendations established by Eni Code, the Board of Directors – on November 18, 2010 – approved unanimously the Management System Guidelines (MSG) "Operations with the interests of

157

##### Table of Contents

directors and statutory auditors and transactions with related parties", which will apply from January 1, 2011. These procedures, that replace the previous similar guidelines, received the prior favorable opinion, expressed unanimously, of the Internal Control Committee, composed entirely of independent directors under the Corporate Governance Code of Borsa Italiana SpA and in accordance with Consob Regulation, to detail the abovementioned disclosure obligations (extending them to the Statutory Auditors). MSG specifies commitments of monitoring, evaluation and motivation related to the preliminary phase and completion of a transaction with a subject of interest of directors or statutory auditors. In this regard, both in the preliminary and deliberation phase, is requested a detailed and documented examination of the reason of the operation, highlighting the interest of company in its completion and the convenience and fairness of underlying terms. Directors involved in matters subject to the Board resolution normally shall not participate in the correspondent discussion and decision and shall leave the room during these procedures. If the person involved is the Chief Executive Officer and the transaction is under his jurisdiction, he shall in any case abstain from taking part in the transaction and shall entrust the matter to the Board of Directors (as provided by Article 2391 of the Civil Code). In any case, if the operation is under the responsibility of the Board of Directors of Eni, it is provided for a non-binding opinion from the Internal Control Committee. Moreover, to ensure compliance with the preliminary and authorizing procedures described, Eni’s Directors and Statutory Auditors shall periodically issue a statement representing the potential interests each one of them has with respect to the Company and the Group, and in any case they shall promptly notify the Chief Executive Officer (or the Chairman, if the matter concerns the latter’s interest) – who shall inform the other Directors and the Statutory Auditors – of the individual transactions that the Company intends to perform, in which they have an interest.

> Compensation

Directors’ compensation shall be determined by the Shareholders’ Meeting, as required by Italian civil law, while compensation of Directors invested with particular tasks in accordance with the By-laws (such as the Board Chairman and the CEO), or for participation in Board Committees, shall be determined by the Board of Directors, upon proposal of the Compensation Committee after consultation with the Board of Statutory Auditors (for more details about compensation policy in 2010, see "Item 6 – Compensation").

> Borrowing powers

Borrowing powers are included in the Company purpose. Moreover, according to the Article 11 of the By-laws, the Company may issue bonds, including convertibles and warrant bonds in compliance with the law.

> Retirement and shareholdings

There are no provisions in the By-laws relating to both the retirement based on age-limit requirements and the number of shares required for director’s qualification.

> Company’s shares

According to Article 5 of the By-laws, the Company’s share capital amounts to euro 4,005,358,876, fully-paid, and is represented by 4,005,358,876 ordinary nominative shares with a nominal value of euro 1 (one) each. As required by Italian legislation on dematerialization of financial instruments, Eni’s shares must be held with "Monte Titoli SpA" (the Italian Central Depository for financial instrument) and their beneficial owners may exercise their rights through special deposit accounts opened with authorized intermediaries, such as banks, brokers and securities dealers.

Shares are indivisible and each share is entitled to one vote. Shareholders are allowed to vote at ordinary and extraordinary Shareholders’ Meeting, also through proxy or mail.

Moreover, according to Article 9 of the By-laws, the Shareholders’ Meeting might resolve to increase the Company capital by issuing shares, including shares of different classes, to be assigned for no consideration to Eni’s employees, pursuant to Article 2349 of the Italian Civil Code. This faculty has not been exercised.

In 1995, Eni established a sponsored ADR (American Depositary Receipts) program directed to U.S. investors. Each of Eni’s ADR is equal to two of Eni’s ordinary shares; Eni’s ADR are listed on the New York Stock Exchange.

Shareholders have the right to participate in profits and any other right as provided by the law and subject to any applicable legal limitations: in particular, the ordinary Shareholders’ Meeting called for the approval of the annual financial statements may allocate the net income resulting after the allotment to the legal reserve, to the payment of a final dividend per share. In addition, during the course of the financial year, the Board of Directors has the faculty, as allowed by the By-laws, to pay interim dividends to the shareholders. Dividends not collected within five years from the day in which they are payable will be prescribed in favor of the Company and allocated to reserves.

> Voting rights

The general provisions on the shares’ "voting rights" are described at the point 6 below. In relation to the appointment of the Board of Directors (Eni’s Board is not a "staggered board") and the Board of Statutory Auditors (see Item 6), Eni’s By-laws provide a voting list system. In particular, pursuant to Article 17 of the By-laws and according to the applicable law, lists may be presented both by shareholders, either individually or jointly with others, representing at least 1% of the share capital, or the different percentage fixed by Consob (the public authority responsible for regulating the Italian securities market) in its regulation, or by the Board of Directors. Each shareholder may present or contribute towards presenting, and vote for, a single list.

There are no provisions in Eni’s By-laws relating to: rights to share in the Company’s profits; redemption provisions; sinking fund provisions; liability to further capital calls by the Company.

> Liquidation rights

In case of liquidation of the Company, the Shareholders’ Meeting would appoint one or more liquidators and determine their powers and remuneration. According to the Italian Law, shareholders would be entitled to the distribution of the remaining liquidated assets of the Company in proportion to the nominal value of their shares, only after payments of all Company’s liabilities and satisfaction of all other creditors.

> Change in shareholders’ rights

To change the shareholders’ rights it is necessary a shareholders’ resolution. In case of any modification of the By-laws provisions relating to voting and dividend rights, resolved by the Shareholders’ Meeting, with the attendance and decision quorum established by the law for extraordinary meetings, shareholders are entitled with a withdrawal right, provided by the Italian Law.

> Shareholders’ Meeting

The Shareholders’ Meeting resolves on the issues set forth by applicable law and Eni’s By-laws, in "ordinary" or "extraordinary" form. Resolutions of ordinary and extraordinary Shareholders’ Meetings in first, second or third call must be approved with the quorum and voting majorities provided for by the law in each case. The Board of Directors may, if it is deemed necessary, determine that both the ordinary and the extraordinary Shareholders’ Meeting shall be called for only one date, with the quorum and voting majorities provided for by the law.

Shareholders’ Meetings are usually held at the Company’s registered office, unless otherwise resolved by the Board of Directors, provided however they are held in Italy.

A Shareholders’ Meeting shall be called by notice published on the Company’s website, as well as in the ways specified by Consob in its regulation, within the legal terms and in accordance with current law. The call notice, which content is defined by the law and Eni’s By-laws, contains all the information to attend and to vote at the meeting including, information on proxy voting and vote by mail (the information is also available on the Company’s website). In the same manner and within the same deadline for publishing the notice calling the meeting, unless otherwise specified by the regulations, the Board of Directors issues a report on the meeting’s agenda.

An ordinary Shareholders’ Meeting is called at least once a year, within 180 days of the end of the Company financial year (on December 31), to approve the financial statements, as the Company is required to draw up consolidated financial statements.

##### Table of Contents

The right to attend the Shareholders’ Meeting applies to those on behalf of whom the intermediary – authorized pursuant to applicable regulations – has sent to the Company, upon request of the person entitled to the right, the statement certifying the ownership of the relative right, at the end of the seventh trading day prior to the date of the Shareholders’ Meeting on first or single call. Credit and debit records entered on accounts after this deadline shall not be considered for the purpose of legitimizing the exercise of voting rights at the Shareholders’ Meeting. The statement made by the authorized intermediary must be received by the Company by the end of the third trading day prior to the date of the Shareholders’ Meeting on first or single call, or other deadline fixed by Consob regulation issued in agreement with the Bank of Italy. The right to attend and to vote at the Shareholders’ Meeting still remains even if the statement is received by the Company after the deadline indicated above, as long as it is received by the opening of the Shareholders’ Meeting. Those who are entitled to vote may appoint a representative in the Shareholders’ Meeting according to law, by means of a written proxy (or in electronic form when this is provided for in specific regulations) and in the ways set forth therein. In this latter case, electronic notification of the proxy may be carried out by using a special section of the Company’s Website, in the ways indicated in the notice calling the meeting. In order to simplify the casting of vote by proxy issued by shareholders who are employees of the Company or of its subsidiaries and members of shareholders associations incorporated under and managed pursuant to current legislation regulating proxies collection, notice boards for communications and rooms to allow proxies collection are made available to said associations according to terms and conditions agreed from time to time by the Company with the legal representatives of said associations. The right to vote may also be exercised by mail according to specific laws and regulations. If envisaged in the notice calling the meeting, those persons entitled to vote may attend the Shareholders’ Meeting through telecommunication means, and exercise their right to vote by electronic means, in accordance with the law, the specific regulatory provisions and the meeting Regulations. The Company may designate a representative for each Shareholders’ Meeting to whom the shareholders may confer a proxy with voting instructions on all or some of the proposals on the agenda in the ways provided by the law and the regulatory provisions, by the end of the second trading day preceding the date set for the Shareholders’ Meeting on first or single call. The proxy is not valid for proposals on which no voting instructions have been provided.

The Chairman of the meeting ensures the regularity of proxies and, in general, the right to attend the meeting.

Shareholders’ Meetings are regulated by the "Eni’s Shareholders’ Meeting Regulation" approved by the ordinary Shareholders’ Meeting of Eni on December 4, 1998, in order to guarantee an efficient development of meetings and the right of each shareholder to express his/her opinion on the items on the agenda.

During Shareholders’ Meetings, the Board of Directors provides wide disclosure on items examined and shareholders can require information on issues in the agenda. Information is provided taking into account of applicable rules on inside information.

> Stock ownership limitation and voting rights restrictions

There are no limitations imposed by Italian law or by Eni’s By-laws on the rights of non-residents in Italy or foreign people to hold shares or vote other than the limitations described below (which are equally applicable to residents and non-residents in Italy).

In accordance with Article 6 of the By-laws, and applying the special rules pursuant to Article 3 of Law Decree No. 332/1994, converted into Law No. 474 of 1994 (Law No. 474/1994), under no circumstances may any party own shares in the Company which constitute a direct or indirect shareholding of more than 3% of the share capital. Exceeding this limit results in a ban on exercising the voting rights and other rights, except for the right to participate in profits, relative to any shareholding that exceeds the limit.

Pursuant to Article 32 of the By-laws and the abovementioned provision of law, shareholdings owned by the Ministry of Economy and Finance, public bodies or organization controlled by them are exempt from this ban.

Finally, this special rule provides that the clause regarding shareholding limits will lose effect if the limit is exceeded as a result of a take-over bid, provided that, as a result of the takeover, the bidder will own a shareholding of at least 75% of the share capital with the right to vote on resolutions concerning the appointment or dismissal of Directors.

> Limitation on changes in control of the Company (Special Powers of the Italian State)

Pursuant to Article 6.2 of the By-laws and to the special rules set out in Law No. 474/1994, the Ministry of Economy and Finance, in agreement with the Ministry for Economic Development, holds special powers that can be exercised in accordance with the criteria set out in the Prime Ministerial Decree of June 10, 2004.

160

##### Table of Contents

These special powers are briefly the following:

(a) |  | objection to the purchase, by parties who are subject to the shareholding limit, of significant shareholdings, i.e. shareholdings that represent at least 3% of the share capital and consist of shares with the right to vote in ordinary Shareholders’ Meetings. The objection, duly justified, must be expressed if the transaction is deemed to be prejudicial to the vital interests of the State, within ten days of the date of the notification which Directors are required to send when a request is made for registration in the register of shareholders. During the period of time allowed for the right of objection to be exercised, the voting rights and other rights, except for the right to participate in profits, connected with the shares that represent the significant shareholding remain suspended. In the event of the right of objection being exercised, by means of a duly justified decision based on the actual prejudicial effect caused by the transaction to the vital interests of the State, the assignee will be forbidden from exercising its voting rights and any rights other than property rights connected with the shares that represent the significant shareholding, and will be required to assign these same shares within one year. In the event of a failure to comply, the Court, at the request of the Ministry of Economy and Finance, will order the sale of the shares representing the significant shareholding according to the procedures set out in Article 2359-ter of the Civil Code;
(b) |  | objection to the signing of agreements, as defined in Article 122 of the Consolidated Law on Finance, in the event that at least 3% of the share capital consisting of shares with the right to vote in ordinary Shareholders’ Meetings is represented in the agreements. For the purpose of allowing the right of objection to be exercised, Consob will inform the Ministry of Economy and Finance of any significant agreements of which it has been notified under the terms of the aforementioned Article 122 of the Consolidated Law on Finance. The right of objection must be exercised within ten days of the date of Consob’s notification. During the period of time allowed for the right of objection to be exercised, the voting rights and any rights other than property rights of the shareholders signing up to the agreement are suspended. If an objection decision is issued with due justification detailing the actual prejudicial effect of the aforesaid agreements to the vital interests of the State, the agreement will be null and void. If the conduct during the Shareholders’ Meeting of the shareholders bound by the agreement reveals that the undertakings given under an agreement pursuant to the aforesaid Article 122 of the Consolidated Law on Finance have been maintained, any resolutions passed with the casting vote of these same shareholders may be challenged;
(c) |  | veto power, if duly justified by an actual prejudicial effect to the vital interests of the State, of resolutions to dissolve the Company, transfer the Company, merge, demerge, transfer the registered office overseas, change the Company purpose, amend the By-laws in a way that withdraws or modifies the powers detailed in letters (a), (b), (c) and the subsequent letter (d); and
(d) |  | appointment of a Director with no right to vote in Board meetings.

Decisions to exercise the powers detailed in letters (a), (b) and (c) may be challenged within sixty days, by the parties entitled to do so, before the Regional Administrative Court of Lazio.

The special powers shall be exercisable with regard to significant and binding cases of general interest (public order, public security, public health and defense) in an appropriate way and measure and proportionally to the safeguarding of these interests, even by means of necessary time limits, without prejudice to compliance with the national and European principles, and in particular with the non-discrimination principle.

The Italian Prime Ministerial Decree of May 20, 2010, after some decisions of the European Court of Justice, repealed paragraph 2 of first article of Prime Ministerial Decree of June 10, 2004, related to the specific circumstances in which the special powers may be exercised.

In order to "promote privatization and the spread of investment in shares" of companies in which the State has a significant shareholding, Article 1, paragraphs 381 to 384 of Law No. 266 of 2005 (2006 Financial Law) introduced the power to add provisions to the By-laws of privatized companies primarily controlled by the State, like Eni, which allow shares or participating financial instruments to be issued that grant the special meeting of its holders the right to request that new shares, even at par value, or new financial instruments be issued to them with the right to vote in ordinary and extraordinary Shareholders’ Meetings. Making this amendment to the By-laws would lead to the shareholding limit referred to in Article 6.1 of the By-laws being removed. At the present time, however, Eni’s By-laws do not contain such any provision.

> Shareholder ownership thresholds

There are no By-laws provisions governing the disclosure of the ownership threshold because the matter is regulated by the Italian law. Under Consolidated Law on Finance12 and Consob Regulation13, any direct or indirect

holding in the voting shares of a listed issuer in excess of 2%14, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 66.6%, 75%, 90% and 95% must be promptly disclosed to the investee company and to Consob. The same disclosure requirements refer to holdings which fall below one of the specified threshold. Due declarations shall be made within five trading days of the date of the transaction triggering the obligation to notify, regardless of the date on which it is to take effect, using the specific forms attached to the abovementioned Regulation.

The relevant thresholds noted above shall be calculated including: (i) shares owned by the reporting person, even if the voting rights belong or are assigned to third parties, or are suspended, as well as shares of which the voting rights belong or are assigned to him; and (ii) shares held through third parties (and shares whose voting rights are assigned to such third parties) such as nominees, trustees or subsidiary companies. The obligation to notify also applies to any direct or indirect participation owned through ADRs. Specific disclosure requirements (with partially different thresholds), are connected to the so-called "potential holdings" (such as holdings of derivatives or other equity-linked securities).

Voting rights attached to listed shares which have not been notified pursuant the abovementioned disclosure requirements may not be exercised. Any resolution or act adopted in violation of such limitation, with the contribution of those undisclosed shares, could be voided if challenged in Court, under the Civil Code, by shareholders or by Consob itself.

The Consolidated Law on Finance regulates additional cross-ownership matters as follows.

Cross-ownership between listed and non-listed companies may not exceed 2% of the shares of the listed company or 10% of the shares of the non-listed company (applying, for calculating these ownership thresholds, the same rules established for holdings in listed companies). The company that last exceed the limit of 2% or 10% interest in a listed or unlisted company respectively, may not exercise the voting rights on the shares held in excess of such thresholds and must sell such shares within the following 12 months. In the event of failure to make the disposal within such time limit, the suspension of voting rights shall apply to the entire shareholding, and any resolution or act adopted with the contribution of relevant shares, could be challenged under the Civil Code. If anyone holds an interest exceeding 2% of the share capital of a listed company, such listed company or any entity controlling such listed company may not acquire an interest exceeding 2% of the share capital of a listed company controlled by said holder. If the foregoing limit is exceeded, the holder who last exceeded the foregoing limit (or both the holders, if it is not possible to ascertain which holder exceeded such limit last) may not exercise the voting right related to the shares exceeding the foregoing limit. In the event of non-compliance, the voting rights attached to the shares in excess of the limit specified shall be suspended and any resolution or act adopted with the contribution of relevant shares could be challenged under the Italian Civil Code. Described limitations are not applicable in case of a takeover bid or exchange tender offer for acquiring at least 60% of the ordinary shares of a listed company.

Under the same Consolidated Law on Finance, any agreement, in whatever form, regarding the exercise of voting rights in a listed company or in its parent company, must be, within five days of stipulation: (i) notified to Consob; (ii) published in abstract form, in the Italian daily press; (iii) filed in the Register of Companies in which the listed company is registered; and (iv) notified to the company with listed shares. In the event of non-compliance with these requirements, the agreements shall be null and void and the voting rights connected to the relevant shares may not be exercised and any resolution or act adopted with the contribution of such shares could be challenged under the Italian Civil Code.

The same provisions also apply to agreements, in whatever form, that: (a) create obligations of consultation prior to the exercise of voting rights in a listed company and in its controlling companies; (b) set limits on the transfer of the related shares or of other financial instruments that entitle holders to buy or subscribe for them; (c) provide for the purchase of the shares or of abovementioned financial instruments; (d) have as their object or effect the exercise, jointly or otherwise, of dominant influence on such companies; and (d-bis) which aim to encourage or frustrate a takeover bid or equity swap, including commitments relating to non-participation in a takeover bid.

Moreover, under the Italian Civil Code (Article 2359-bis), a subsidiary may acquire shares of the parent company only within the limits of distributable profits and available reserves as resulting from the last approved balance sheet. Only fully-paid shares can be purchased. The purchase must be approved by the Shareholders’ Meeting and, in any case, the nominal value of shares purchased may not exceed a fifth of the capital of the parent company – if the latter is a listed company – taking into account for this purpose the shares held by the same parent company or its subsidiaries.

(14) |  | Moreover, based on reasoned investor protection and/or market efficiency aims, Consob is entitled to fix the first relevant threshold to a measure lower than 2%, by its decree (as provided for Law Decree No. 5 of February 2, 2009, converted into Law No. 33 of April 9, 2009). This faculty may be exercised only for definite period of time, with regard to public companies with high capitalization level.

162

##### Table of Contents

Finally, in accordance with Law No. 287 of October 10, 1990, any merger or acquisition of sole or joint control over a company that would create or strengthen a dominant position in the domestic market in a manner that eliminates or significantly reduces competition is prohibited and mergers and acquisition of specified dimension must be subject to preventive authorization of Italian Antitrust Authority15. However, if the acquiring party and the company to be acquired operate in more than one EU member state and together exceed certain revenue thresholds, the antitrust approval of the acquisition falls within the exclusive jurisdiction of the European Commission.

> Changes in share capital

Eni’s By-laws do not provide for more stringent conditions than is required by the law.

Share capital increases are resolved by a shareholders’ resolution at an extraordinary Shareholders’ Meeting. According to Italian law, shareholders have a pre-emptive right to subscribe for new issues of shares and corporate bonds convertible into shares in proportion to their respective shareholdings. Subject to definite conditions, designated to prevent reduction of (actual) shareholders rights, and to preserve the Company’s interest, the pre-emptive right may be waived or limited by a shareholders’ resolution at an extraordinary Shareholders’ Meeting with the consent of more than 50% of the shares outstanding. The shareholders’ pre-emptive right is also waived by the law, in case of contributions in-kind.

Material Contracts

None.

Exchange Controls

There are no exchange controls in Italy. Residents and non-residents in Italy may effect any investments, divestments and other transactions that entail a transfer of assets to or from Italy, subject only to the reporting, record-keeping and disclosure requirements described below. In particular, residents of Italy may hold foreign currency and foreign securities of any kind, within and outside Italy, while non-residents may invest in Italian securities without restriction and may export from Italy cash, instruments of credit or payment and securities, whether in foreign currency or euro, representing interest, dividends, other asset distributions and the proceeds of dispositions.

Updated reporting and record-keeping requirements are contained in the Italian legislation which implements an EU directive regarding the free movement of capital. Such legislation requires that transfers into or out of Italy of cash or securities in excess of euro 12.5 thousand be reported in writing to the Ufficio Italiano Cambi (the Italian Exchange Office) by residents or non-residents that effect such transfers directly, or by banks, securities dealers or Poste Italiane SpA (Italian Mail) that effect such transactions on their behalf. In addition, banks, securities dealers or Poste Italiane SpA effecting such transactions on behalf of residents or non-residents of Italy are required to maintain records of such transactions for five years, which records may be inspected at any time by Italian tax and judicial authorities.

Non-compliance with these reporting and record-keeping requirements may result in administrative fines or, in the case of false reporting and in certain cases of incomplete reporting, criminal penalties. The Ufficio Italiano Cambi will maintain reports for a period of ten years and may use them, directly or through other government offices, to police money laundering, tax evasion and any other crime or violation.

Taxation

The information set forth below is a summary only, and Italian, the United States and other tax laws may change from time to time. Holders of shares and ADRs should consult with their professional advisors as to the tax consequences of their ownership and disposition of the shares and ADRs, including, in particular, the effect of tax laws of any other jurisdiction.

> Italian Taxation

The following is a summary of the material Italian tax consequences of the ownership and disposition of shares or ADRs as at the date hereof and does not purport to be a complete analysis of all potential tax effects relevant to the ownership or disposition of shares or ADRs.

> Income tax

Dividends, in respect of 2010 profits, received by Italian resident individuals in relation to interest exceeding 2% of the voting rights or 5% of the share capital ("substantial interest") are included in the taxable income subject to personal income tax to the extent of 49.72% of their amount. Personal income tax applies at progressive rates ranging from 23% to 43% plus local surtaxes. Dividends received by Italian resident individuals in relation to non-substantial interest not related to the conduct of a business are subject to a substitute tax of 12.5% withheld at the source by the dividend paying agent. This being the case, the dividend is not to be included in the individual’s tax return. If the non-substantial interest is related to the conduct of a business, dividends received in respect of 2009 profits are included in the taxable business income to the extent of 49.72% of their amount.

Despite the above statement, dividends are included in the taxable income at 40% to the extent they relate to un-distributed profit of 2007 and previous years.

Dividends received by Italian pension funds are included in the overall result of the pension funds subject to an 11% substitute tax. Dividends received by Italian collective investment funds are included in the overall result of the collective investment funds subject to a 12.5% substitute tax. Dividends received by Italian real estate investment funds are not subject to tax in the hands of the real estate investment funds (under certain circumstances a 1% tax on net asset value is applied). Entities exempt from Ires (company income tax) are subject to the substitute tax at the rate of 27%.

Dividends paid to non-Italian residents are subject to the same substitute tax levied at source by the dividend paying agent at the rate of 27%, provided that the interest is not connected to an Italian permanent establishment. Up to four-ninths of the substitute tax withheld might be recovered by the non-resident shareholder from the Italian Tax Authorities upon provision of evidence of full payment of income tax on such dividend in his/her country of residence in an amount at least equal to the total refund claimed.

Dividends are subject to the 1.375% substitute tax introduced by Financial Bill for 2008 where the conditions in Article 27, paragraph 3-ter, Presidential Decree No. 600 of 1973 are met, i.e. dividends are paid to companies and entities subject to a corporate income tax in a European Union member state or in Norway.

The substitute tax may also be reduced under the tax treaty in force between Italy and the country of residence of the Beneficial Owner of the dividend. Italy has executed income tax treaties with approximately 70 foreign countries, including all EU member states, Argentina, Australia, Brazil, Canada, Japan, New Zealand, Norway, Switzerland, the USA and some countries in Africa, the Middle East and the Far East. Generally speaking, it should be noted that tax treaties are not applicable where the holder is a tax-exempt entity or, with few exceptions, a partnership or a trust.

In order to obtain the treaty benefit (reduced substitute tax rate) at the same time of payment, the Beneficial Owner must file an application to the dividend paying agent chosen by the Depositary stating the existence of the conditions for the applicability of the treaty benefit, together with a certification issued by the foreign Tax Authorities stating that the shareholder is a resident of that country for treaty purposes.

Under the tax treaty between the USA and Italy, dividends derived and beneficially owned by a U.S. resident who holds less than 25% of the Company’s shares are subject to an Italian withholding or substitute tax at a reduced rate of 15%, provided that the interest is not effectively connected with a permanent establishment in Italy through which the U.S. resident carries on a business or a fixed establishment in Italy through which such U.S. resident performs independent personal services (for further details please refer to the relevant provisions set forth in the Italy-U.S. Tax Treaty). In the absence of such conditions, the dividend paying agent will deduct from the gross amount of the dividend the substitute tax at the statutory rate of 27%. Based on the certification procedure required by the Italian Tax Authorities, to benefit from the direct application of the 15% substitute tax the U.S. shareholder must provide the dividend paying agent with a certificate obtained from the U.S. Internal Revenue Service (the "IRS") with respect to each dividend payment. The request for that certificate must include a statement, signed under penalties for perjury, to the effect that the shareholder is a U.S. resident individual or corporation, and does not maintain a permanent establishment in Italy, and must set forth other required information. The normal time for processing requests for certification by the IRS is normally about six to eight weeks.

164

##### Table of Contents

Where the Beneficial Owner has not provided the abovementioned documentation, the dividend paying agent will deduct from the gross amount of the dividend the substitute tax at the statutory rate of 27%. The U.S. recipient will then be entitled to claim from the Italian Tax Authorities the difference ("treaty refund") between the domestic rate and the treaty one by filing specific forms (certificate) with the Italian Tax Authorities.

According to the Italian tax law as reflected in the Deposit Agreement, the Company is not involved: (i) in withholding amounts due by holders of ADRs to relevant taxing authorities in connection with any distributions relating to ADRs; or (ii) in the procedures through which certain holders of ADRs may obtain tax rebates, credits, refunds or other similar benefits. Pursuant to the Deposit Agreement, the custodian and the Depositary have undertaken to use reasonable efforts to make and maintain arrangements to enable persons that are considered to be resident in the USA for purposes of applicable law to receive any rebates or tax credits (pursuant to treaty or otherwise) relating to distributions on the ADRs to which such persons are entitled. In addition, the Depositary has agreed to establish procedures to enable all holders to take advantage of any rebates or tax credits (pursuant to treaty or otherwise) relating to distributions on the ADRs to which such holders are entitled and to provide, at least annually, a written notice, in a form previously agreed to by the Company, to the holders of ADRs of any necessary actions to be undertaken by such Holders.

> Capital gains tax

This paragraph applies with respect to capital gains out of the scope of a business activity carried out in Italy.

Gains realized by Italian resident individuals upon the sale of substantial interest is included in the taxable base subject to personal income tax to the extent of 49.72% of their amount, while gains realized upon the sale of non-substantial interest is subject to a substitute tax at a 12.5% rate.

For gains deriving from the sale of non-substantial interest, two different systems may be applied at the option of the shareholder as an alternative to the filing of the tax return:

• |  | the so-called "administered savings" tax regime (risparmio amministrato), based on which intermediaries acting as shares depositaries shall apply a substitute tax (12.5%) on each gain, on a cash basis. If the sale of shares generated a loss, said loss may be carried forward up to the fourth following year; and
• |  | the so-called "portfolio management" tax regime (risparmio gestito) which is applicable when the shares form part of a portfolio managed by an Italian asset management company. The accrued net profit of the portfolio is subject to a 12.5% substitute tax to be applied by the portfolio.

Gains realized by non-residents from non substantial interest in listed companies are deemed not to be realized in Italy and consequently are not subject to the capital gains tax.

On the contrary, gains realized by non-residents from substantial interest even in listed companies are deemed to be realized in Italy and consequently they are subject to the capital gains tax.

However, double taxation treaties may eliminate the capital gains tax. Under the income tax convention between the USA and Italy, a U.S. resident will not be subject to the capital gains tax unless the shares or ADRs form part of the business property of a permanent establishment of the holder in Italy or pertain to a fixed establishment available to a shareholder in Italy for the purposes of performing independent personal services. U.S. residents who sell shares may be required to produce appropriate documentation establishing that the abovementioned conditions of non-taxability pursuant to the convention have been satisfied.

> Inheritance and gift tax

Pursuant to Law Decree No. 262 of October 3, 2006, converted with amendments by Law No. 286 of November 24, 2006 effective from November 29, 2006, and Law No. 296 of December 27, 2006, the transfers of any valuable assets (including shares) as a result of death or donation (or other transfers for no consideration) and the creation of liens on such assets for a specific purpose are taxed as follows:

(a) |  | 4 per cent: if the transfer is made to spouses and direct descendants or ancestors; in this case, the transfer is subject to tax on the value exceeding euro 1,000,000 (per beneficiary);
(b) |  | 6 per cent: if the transfer if made to brothers and sisters; in this case, the transfer is subject to the tax on the value exceeding euro 100,000 (per beneficiary);
(c) |  | 6 per cent: if the transfer is made to relatives up to the fourth degree, to persons related by direct affinity as well as to persons related by collateral affinity up to the third degree; and
(d) |  | 8 per cent: in all other cases.

165

##### Table of Contents

If the transfer is made in favor of persons with severe disabilities, the tax applies on the value exceeding euro 1,500,000. Moreover, an anti-avoidance rule is provided for by Law No. 383 of October 18, 2001 for any gift of assets (including shares) which, if sold for consideration, would give rise to capital gains subject to a substitute tax (imposta sostitutiva) provided for by Decree No. 461 of November 21, 1997. In particular, if the donee sells the shares for consideration within five years from the receipt thereof as a gift, the donee is required to pay a relevant substitute tax on capital gains as if the gift had never taken place.

United States Taxation

The following is a summary of certain U.S. federal income tax consequences to U.S. Holders (as defined below) of the ownership and disposition of Shares or ADSs. This summary is addressed to U.S. Holders that hold Shares or ADSs as capital assets, and does not purport to address all material tax consequences of the ownership of Shares or ADSs. The summary does not address special classes of investors, such as tax-exempt entities, dealers in securities, traders in securities that elect to mark-to-market, certain insurance companies, broker-dealers, investors liable for alternative minimum tax, investors that actually or constructively own 10% or more of Eni SpA’s Shares, investors that hold Shares or ADSs as part of a straddle or a hedging or conversion transaction and investors whose "functional currency" is not the U.S. dollar.

This summary is based on the tax laws of the USA (including the Internal Revenue Code of 1986, as amended, (the "Code"), its legislative history, existing and proposed regulations thereunder, published rulings and court decisions) as in effect on the date hereof, and which are subject to change (or changes in interpretation), possibly with retroactive effect. The summary is based in part on representations of the Depositary and assumes that each obligation in the Deposit Agreement and any related agreement will be performed in accordance with its terms. U.S. Holders should consult their own tax advisors to determine the U.S. federal, state and local and foreign tax consequences to them of the ownership and disposition of Shares or ADSs.

If a partnership holds the Shares or ADSs, the USA federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. A partner in a partnership holding the Shares or ADSs should consult its tax advisor with regard to the USA federal income tax treatment of an investment in the Shares or ADSs.

As used in this section, the term "U.S. Holder" means a beneficial owner of Shares or ADSs who or that is: (i) a citizen or resident of the USA; (ii) a domestic corporation; (iii) an estate the income of which is subject to the U.S. federal income tax without regard to its source; or (iv) a trust if a court within the USA is able to exercise primary supervision over the administration of the trust and one or more USA persons have the authority to control all substantial decisions of the trust.

The discussion does not address any aspects of USA taxation other than federal income taxation. In particular, U.S. Holders are urged to confirm their eligibility for benefits under the income tax convention between the USA and Italy with their advisors and to discuss with their advisors any possible consequences of their failure to qualify for such benefits.

In general, and taking into account the earlier assumptions, for the U.S. federal income tax purposes, U.S. Holders who own ADSs evidencing ADSs will be treated as owners of the underlying Shares. Exchanges of Shares for ADSs and ADSs for Shares generally will not be subject to the U.S. federal income tax.

> Dividends

Subject to the passive foreign investment company, or PFIC, rules discussed below, distributions paid on the shares generally will be treated as dividends for U.S. federal income tax purposes to the extent paid out of Eni SpA’s current or accumulated earnings and profits as determined for U.S. federal income tax purposes, but will not be eligible for the dividends-received deduction generally allowed to corporations. To the extent that a distribution exceeds Eni SpA’s earnings and profits, it will be treated, first, as a non-taxable return of capital to the extent of the U.S. Holder’s tax basis in the Shares or ADSs, and thereafter as capital gain. A U.S. Holder will be subject to U.S. federal taxation, on the date of actual or constructive receipt by the U.S. Holder (in the case of Shares) or by the Depositary (in the case of ADSs) with respect to the gross amount of any dividends, including any Italian tax withheld therefrom, without regard to whether any portion of such tax may be refunded to the U.S. Holder by the Italian tax Authorities. If you are a non-corporate U.S. Holder, dividends paid to you in taxable years beginning before January 1, 2013 that constitute qualified dividend income will be taxable to you at a maximum tax rate of 15% provided that you hold the Shares or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Dividends we pay with respect to the Shares or ADSs generally will be qualified dividend income. The amount of the dividend distribution that you must

166

##### Table of Contents

include in your income as a U.S. Holder will be the U.S. dollar value of the euro payments made, determined at the spot euro/U.S. dollar rate on the date the dividend distribution is includible in your income, regardless of whether the payment is in fact converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income to the date you convert the payment into U.S. dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income. The gain or loss generally will be income or loss from sources within the USA for foreign tax credit limitation purposes.

Subject to certain conditions and limitations, Italian tax withheld from dividends will be treated as a foreign income tax eligible for credit against the U.S. Holder’s U.S. federal income tax liability. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the maximum 15% tax rate. To the extent a refund of the tax withheld is available to a U.S. Holder under Italian law or under the income tax convention, the amount of tax withheld that is refundable will not be eligible for credit against your USA federal income tax liability. See "Italian Taxation – Income Tax" above, for the procedures for obtaining a tax refund. For foreign tax credit purposes, dividends paid on the shares will be income from sources outside the USA and will, depending on your circumstances, generally be either "passive" or "general" income for purposes of computing the foreign tax credit allowable to you.

> Sale or exchange of shares

Subject to the PFIC rules discussed below, a U.S. Holder generally will recognize gain or loss for U.S. federal income tax purposes on the sale or exchange of Shares or ADSs equal to the difference between the U.S. Holder’s adjusted basis in the Shares or ADSs (determined in U.S. dollars), as the case may be, and the amount realized on the sale or exchange (or if the amount realized is denominated in a foreign currency its U.S. dollar equivalent, determined at the spot rate on the date of disposition). Generally, such gain or loss will be treated as capital gain or loss if the Shares or ADSs are held as capital assets and will be a long-term capital gain or loss if the Shares or ADSs have been held for more than one year on the date of such sale or exchange. Long-term capital gain of a non-corporate U.S. Holder that is recognized in taxable years beginning before January 1, 2013 is generally subject to a maximum tax rate of 15%. In addition, any such gain or loss realized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes.

> PFIC rules

Eni SpA believes that Shares and ADSs should not be treated as stock of a PFIC for USA federal income tax purposes, but this conclusion is a factual determination that is made annually and thus may be subject to change. If Eni SpA were to be treated as a PFIC, unless a U.S. holder elects to be taxed annually on a mark-to-market basis with respect to the Shares or ADSs, gain realized on the sale or other disposition of your Shares or ADSs would in general not be treated as capital gain. Instead, if you are a U.S. holder, you would be treated as if you had realized such gain and certain "excess distributions" ratably over your holding period for the Shares or ADSs and would be taxed at the highest tax rate in effect for each such year to which the gain or distribution was allocated, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions, your Shares or ADSs will be treated as stock in a PFIC if Eni SpA were a PFIC at any time during your holding period in your Shares or ADSs. Dividends that you receive from Eni SpA will not be eligible for the special tax rates applicable to qualified dividend income if Eni SpA is treated as a PFIC with respect to you either in the taxable year of the distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income.

Item 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the possibility that the exposure to fluctuations in currency exchange rates, interest rates or commodity prices will adversely affect the value of the Group’s financial assets, liabilities or expected future cash flows. Eni’s financial performance is particularly sensitive to changes in the price of crude oil and movements in the euro/U.S. $ exchange rate. Overall, a rise in the price of crude oil has a positive effect on Eni’s results from operations and liquidity due to increased revenues from oil and gas production. Conversely, a decline in crude oil prices reduces Eni’s results from operations and liquidity.

The impact of changes in crude oil prices on the Company’s downstream gas and refining and marketing businesses and petrochemical operations depends upon the speed at which the prices of finished products adjust to reflect changes in crude oil prices. In addition, the Group’s activities are, to various degrees, sensitive to fluctuations in the euro/U.S. $ exchange rate as commodities are generally priced internationally in U.S. dollars or linked to dollar denominated products as in the case of gas prices. Overall, an appreciation of the euro against the U.S. dollar reduces the Group’s results from operations and liquidity, and vice versa.

Due to a changed competitive environment in the European gas market and also considering the development of highly liquid spot markets for gas and volatile gas margins, management adopted in 2010 new risk management policies and instruments to safeguard the value of the Company’s assets in the gas value chain and to seek to profit from market and trading opportunities. These new policies and instrument will be fully implemented in 2011. As part of its new risk management strategy, the Company plans to enter into commodity derivatives transactions targeting different objectives.

(i) |  | On one hand, management plans to enter commodity derivative transactions to hedge the risk of variability in future cash flows on already contracted or highly probable future sales exposed to commodity risk depending on the circumstance that costs of supplies may be indexed to different market and oil benchmarks compared to the indexing of selling prices. Management plans to implement tight correlation between such commodity derivatives transactions and underlying physical contracts in order to account for those derivatives in accordance with hedging accounting in compliance with IAS 39, where possible;
(ii) |  | on the other hand, management plans to enter purchase/sale commodity contracts in both commodity and financial markets for speculative purposes in order to alter the risk profile associated with a portfolio of gas contracts (purchase contracts, transport entitlements, storage capacity) or leverage any price differences in the marketplace, seeking to increase margins on existing assets in case of favourable trends in the commodity pricing environment or seeking a potential profit based on expectations of future prices. These contracts may lead to gains as well as losses, which, in each case, may be significant. Those derivatives will be accounted for through profit and loss, resulting in higher volatility in the gas business’ operating profit.

The Company may also enters into commodity derivatives from time to time, to hedge exposure to variability in future cash flows due to movements in commodity prices, in view of pursuing acquisitions of oil and gas reserves as part of the Company’s ordinary asset portfolio management or other strategic initiatives.

As part of its financing and cash management activities, the Company uses derivative instruments to manage its exposure to changes in interest rates and foreign exchange rates. These instruments are principally interest rate and currency swaps.

Please refer to Note 34 to the Consolidated Financial Statements for a qualitative and quantitative discussion of the Company’s exposure to market risks.

Item 15. CONTROLS AND PROCEDURES

> Disclosure controls and procedures

In designing and evaluating the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act"), the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Company’s management necessarily was required to apply its judgment in evaluating the cost benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

It should be noted that the Company has investments in certain non-consolidated entities. As the Company does not control or manage these entities, its disclosure controls and procedures with respect to such entities are necessarily more limited than those it maintains with respect to its consolidated subsidiaries.

The Company’s management, with the participation of the principal executive officer and principal financial officer, has evaluated the effectiveness of the design and operation of its disclosure controls and procedures pursuant to Rule 13a-14(c) under the Exchange Act as of the end of the period covered by this Annual Report on Form 20-F. Based on that evaluation, the principal executive officer and principal financial officer have concluded that these disclosure controls and procedures are effective.

> Management’s Annual Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rules 13a-15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and even when determined to be effective can only provide reasonable assurance with respect to financial statement preparation and presentation. Also, the effectiveness of an internal control system may change over time.

The Internal Control Committee assists the Board of Directors in setting out the main principles for the internal control system so as to appropriately identify and adequately evaluate, manage, and monitor the main risks related to the Company and its subsidiaries, by laying down the compatibility criteria between said risks and sound corporate management. In addition this Committee assesses, at least annually, the adequacy, effectiveness, and actual operations of the internal control system.

The Company’s management, including the Chief Executive Officer and the Chief Financial Officer, conducted an evaluation of the effectiveness of its internal control over financial reporting based on the Internal Control -Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on the results of this evaluation, the Group’s management concluded that its internal control over financial reporting was effective as of December 31, 2010.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2010, has been audited by Reconta Ernst & Young SpA, an independent registered public accounting firm, as stated in its report that is included on page F-2 of this Annual Report on Form 20-F.

> Changes in Internal Control over Financial Reporting

There have not been changes in the Company’s internal control over financial reporting that occurred during the period covered by this Form 20-F that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 16A. Board of Statutory Auditors Financial Expert

Eni’s Board of Statutory Auditors has determined that five members of Eni’s Board of Statutory Auditors, qualify as "audit committee financial expert", as defined in Item 16A of Form 20-F. These five members are: Ugo Marinelli, who is the Chairman of the Board, and Roberto Ferranti, Luigi Mandolesi, Tiziano Onesti and Giorgio Silva. All members are independent.

Item 16B. Code of Ethics

Eni adopted a code of ethics that applies to all Eni’s employees including Eni’s principal executive officer, principal financial officer and principal accounting officer. Eni published its code of ethics on Eni’s website. It is accessible at www.eni.it, under the section Sustainability – Corporate Governance and Corporate Ethics – Code of Ethics. A copy of this code of ethics is included as an exhibit to this Annual Report on Form 20-F.

Eni’s code of ethics contains ethical guidelines, describes corporate values and requires standards of business conduct and moral integrity. The ethical guidelines are designed to deter wrongdoing and to promote honest and ethical conduct, compliance with applicable laws and regulations and internal reporting of violations of the guidelines. The code affirms the principles of accounting transparency and internal control and endorses human rights and the issue of the sustainability of the business model.

Item 16C. Principal Accountant Fees and Services

> Pre-approval policies and procedures of the Internal Control Committee

The Board of Statutory Auditors has adopted a pre-approval policy for audit and non-audit services that set forth the procedures and the conditions pursuant to which services proposed to be performed by the principal auditors may be pre-approved. Such policy is applied to entities within the Eni Group which are either controlled or jointly-controlled (directly or indirectly) by Eni SpA. According to this policy, permissible services within the other audit services category are pre-approved by the Board of Statutory Auditors. The Board of Statutory Auditors approval is required on a case by case basis for those requests regarding: (i) audit-related services; and (ii) non-audit services to be performed by the external auditors which are permissible under applicable rules and regulations. In such cases, the Company’s internal audit department is charged with performing an initial assessment of each request to be submitted to the Board of Statutory Auditors for approval. The internal audit department periodically reports to Eni’s Board of Statutory Auditors on the status of both pre-approved services and services approved on a case-by-case basis rendered by the external auditors.

During 2010, no audit-related fees, tax fees or other non-audit fees were approved by the Board of Statutory Auditors pursuant to the de minimis exception to the pre-approval requirement provided by paragraph (c)(7)(i) (c) of Rule 2-01 of Regulation S-X.

Item 16D. Exemptions from the Listing Standards for Audit Committees

Making use of the exemption provided by Rule 10A-3(c)(3) for non-U.S. private issuers, Eni 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 "Item 6 – Board of Statutory Auditors" above).

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers

The Issuer and its affiliated purchasers have not executed any purchase of equity securities of the Issuer from 2009 as of the date of the 20-F filing for the year ended December 31, 2010. All relevant authorizations previously granted by the General Shareholders’ Meeting to the Company management to execute any purchase of equity securities have expired. As of December 31, 2010, Eni’s treasury shares in portfolio amounted to No. 382,952,240 (nominal value euro 1 each) corresponding to 9.56% of share capital of Eni, for a total book value of euro 6,756 million.

Item 16F. Change in Registrant’s Certifying Accountant

Not applicable.

Item 16G. Significant Differences in Corporate Governance Practices as per Section 303A.11 of the New York Stock Exchange Listed Company Manual

Corporate governance. Eni’s governance structure follows the traditional model as defined by the Italian Civil Code 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. one-tier model which provides for the Board of Directors as the sole corporate body responsible for management and for the establishment of an Audit Committee within the same Board, for monitoring activities.

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, also with reference to Corporate Governance Code promoted by Borsa Italiana (hereafter Borsa Italiana Code), which Eni has adopted.

> Independent Directors

NYSE standards. Under NYSE standards U.S. listed companies’ Boards shall have a majority of independent directors. A director qualifies as independent when the Board 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 be deemed independent if he/she or an immediate family member has a 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 Consolidated Law on Finance states that at least one member, or two members if the Board is composed by more than seven members, shall possess the independence requirements provided for Statutory Auditors of listed companies.
In particular, a director may not be deemed independent if he/she or an immediate family member has relationships with the issuer, with its directors or with the companies in the same group of the issuer that could influence his or her judgment.
Eni’s By-laws increases the number of independent directors provided by the law and states that at least one member, if the Board is made up by up to five members, or three Board members, in case the Board is made up by more than five members, shall have the independence requirement.
Eni’s Code foresees further independence requirements, in line with the ones provided by the Borsa Italiana Code, that recommends that the Board of Directors includes an adequate number of independent non-executive directors; independence is defined as not being currently or recently involved in any commercial relationship – either directly or indirectly – with the issuer or other parties associated with the issuer and which may influence his/her independent judgment.
In accordance with Eni’s By-laws, the Board of Directors, after its appointment by the Shareholders’ Meeting and periodically, evaluates the independence of directors. Eni’s Code also provides for the Board of Statutory Auditors to verify the proper application of criteria and procedures adopted by the Board of Directors to evaluate the independence of its members.
The results of the assessments of the Board shall be communicated to the market.

In accordance with Eni’s By-laws, should the independence 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. Board members are

174

##### Table of Contents

expected to inform the Company in case they lose their independence requirements or of any reasons for ineligibility or incompatibility that might arise.

> Meetings of non Executive Directors

NYSE standards. Non-executive directors, including those who are not independent, must meet on a regularly basis in the absence of 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. The Eni Code allows independent directors to decide whether to meet in the absence of the other directors for discussion of topics deemed relevant to the functioning of the Board. This express provision allowing such meetings to take place was requested by the independent directors themselves, in order to have greater flexibility, to deal with actual requirements. In 2010, the independent directors, in consideration of the frequency of the Board meetings, had numerous opportunities to meet, holding formal and informal meetings to hold discussions and exchange opinions.

> Audit Committee

NYSE standards. U.S. listed companies shall 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 2005, the Board of Directors, as allowed by the rules of the U.S. Securities and Exchange Commission applicable to foreign issuers listed on the regulated U.S. markets, identified the Board of Statutory Auditors as the body that, since June 1, 2005, has been fulfilling, within the limits set forth by Italian laws, the responsibilities assigned to the Audit Committee of such foreign issuers by the Sarbanes-Oxley Act and the SEC regulations (see "Item 6 – Board of Statutory Auditors").
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 "Item 6 – Board of Statutory Auditors".

> Nominating/Corporate Governance Committee

NYSE standards. U.S. listed companies shall have a nominating/corporate governance committee (or equivalent body) composed entirely of independent directors that is 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 Borsa Italiana 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.

> Code of Business Conduct and Ethics

NYSE standards. The NYSE listing standards require each U.S. listed company to adopt a code of business conduct and ethics for its directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers.

Eni standards. Eni’s Code of Ethics – adopted on March 14, 2008, replacing the previous version of 1998 – represents a clear definition of the value system that Eni recognizes, accepts and upholds and the responsibilities that Eni assumes internally and externally in order to ensure that all business activities are conducted in compliance with laws, in a context of fair competition, with honesty, integrity, correctness and in good faith, respecting the legitimate

175

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

> > The Board of Directors and Shareholders of Eni S.p.A

> > We have audited Eni S.p.A’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Eni S.p.A management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting on page 171. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

> > We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

> > A company’s 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. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

> > Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

> > In our opinion, Eni S.p.A maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria.

> > We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Eni S.p.A as of December 31, 2010 and the related consolidated profit and loss account and consolidated statements of comprehensive income, changes in shareholders' equity and cash flows for the year then ended and our report dated April 7, 2011 expressed an unqualified opinion thereon.

Notes to the Consolidated Financial Statements

1 Basis of presentation

The Consolidated Financial Statements of Eni Group have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). Oil and natural gas exploration and production activity is accounted for in conformity with internationally accepted accounting principles. Specifically, this concerns the determination of the amortization expenses using the unit-of-production method and the recognition of the production-sharing agreement and buy-back contracts. The Consolidated Financial Statements have been prepared on a historical cost basis, taking into account where appropriate of any value adjustments, except for certain items that under IFRS must be recognized at fair value as described in the summary of significant accounting policies paragraph.

The Consolidated Financial Statements include the statutory accounts of Eni SpA and the accounts of subsidiaries where the company holds the right to directly or indirectly exercise control, determine financial and management decisions and obtain economic and financial benefits. For entities acting as sole-operator in the management of oil and gas contracts on behalf of companies participating in a joint venture, the activities are financed proportionately based on a budget approved by the participating companies upon presentation of periodical reports of proceeds and expenses. Costs and revenues and other operating data (production, reserves, etc.) of the project, as well as the related obligations arising from the project, are recognized proportionally directly in the financial statements of the companies involved. The exclusion from consolidation of some subsidiaries, which are not material either individually or overall, has not produced significant1 economic and financial effects on the Consolidated Financial Statements. These interests are accounted for as described below under the item "Financial fixed assets".

Subsidiaries’ financial statements are audited by the independent auditors who examine and certify also the information required for the preparation of the Consolidated Financial Statements. The 2010 Consolidated Financial Statements approved by Eni’s Board of Directors on March 10, 2011 were audited by the independent auditor Reconta Ernst & Young SpA. The independent auditor of Eni SpA, as the main auditor is wholly in charge of the auditing activities of the Consolidated Financial Statements; when there are other independent auditors, it takes the responsibility of their work. Amounts in the financial statements and in the notes are expressed in millions of euros (euro million).

2 Principles of consolidation

Interest in consolidated companies
Assets and liabilities, revenues and expenses related to fully consolidated subsidiaries are wholly incorporated in the Consolidated Financial Statements; the book value of interests in these subsidiaries is eliminated against the corresponding share of the shareholders’ equity by attributing to each of the balance sheet items its fair value at the acquisition date. When acquired, the net equity of controlled subsidiaries is initially recognized at fair value. The excess of the purchase price of an acquired entity over the total fair value assigned to assets acquired and liabilities assumed is recognized as goodwill; negative goodwill is recognized in the profit and loss account.

Equity and net profit of non-controlling interests are included in specific lines of equity and profit and loss account. If the partial control is acquired, this share of equity is determined using the proportionate share of the fair value of assets and liabilities, excluding any related goodwill, at the time when control is acquired (partial goodwill); as an alternative, it is allowed the recognition of the entire amount of goodwill deriving from the acquisition, taking into account therefore also the portion attributable to the non-controlling interests (full goodwill method); on this regard, the non-controlling interests are measured at their total fair value which therefore includes the goodwill attributable to them2. The method of measuring goodwill (partial goodwill or full goodwill) is selective for each business combination.

The purchase of additional ownership interests in subsidiaries from non-controlling interests is recognized in equity and represents the excess of the amount paid over the carrying value of the non-controlling interests acquired; similarly, are recognized in equity the effects associated with the sale of non-controlling interests in consolidated subsidiaries without loss of control.

(1) |  | According to the requirements of the Framework of international accounting standards, information is material if its omission or misstatement could influence the economic decisions that users make on the basis of the financial statements.
(2) |  | The choice between partial goodwill and full goodwill method is available also for business combinations resulting in the recognition of a "negative goodwill" in profit or loss account (gain on bargain purchase).

##### Table of Contents

Inter-company transactions
Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated.

Unrealized losses are not eliminated since they are considered an impairment indicator of the asset transferred.

Foreign currency translation
Financial statements of foreign companies having a functional currency other than the euro, that represents the Group’s functional currency, are translated into the presentation currency using closing exchange rates for assets and liabilities, historical exchange rates for equity accounts and average rates for the period for the profit and loss account (source: Bank of Italy). Cumulative exchange rate differences resulting from this translation are recognized in shareholders’ equity under "Other reserves" in proportion to the Group’s interest and under "Non-controlling interest" for the portion related to non-controlling interests’ share. Cumulative exchange rate differences are charged to the profit and loss account when the entity disposes the entire interest in a foreign operation or at the loss of control of a foreign subsidiary. On the partial disposal, without losing control, the proportionate share of cumulative amount of exchange differences related to the disposed interest is recognized in equity to non-controlling interests. Financial statements of foreign subsidiaries which are translated into the euro are denominated in the functional currencies of the countries where the entities operate. The U.S. dollar is the prevalent functional currency for the entities that do not use the euro. The main foreign exchange rates used to translate the financial statements adopting a different functional currency are indicated below:

3 Summary of significant accounting policies

The most significant accounting policies used in the preparation of the Consolidated Financial Statements are described below.

Current assets
Held for trading financial assets and available-for-sale financial assets are measured at fair value with gains or losses recognized in the profit and loss account under "Financial income (expense)"3 and to the equity reserve related to other comprehensive income, respectively. In the latter case, changes in fair value recognized in equity are charged to the profit and loss account when they are impaired or realized. The objective evidence that an impairment loss has occurred is verified considering, inter alia, significant breaches of contracts, serious financial difficulties or the high probability of insolvency of the counterparty; asset write downs are included in the carrying amount.

Available-for-sale financial assets include financial assets other than derivative financial instruments, loans and receivables, held for trading financial assets and held-to-maturity financial assets.

The fair value of financial instruments is determined by market quotations or, in their absence, it is estimated adopting suitable financial valuation models which take into account all the factors adopted by market operators and prices obtained in similar recent transactions in the market.

Interests and dividends on financial assets stated at fair value with gains or losses reflected in the profit and loss account are accounted for on an accrual basis in "Financial income (expense)" and "Other gain (loss) from investments", respectively. When the purchase or sale of a financial asset under a contract whose terms require

(3) |  | Starting from 2009, changes in the fair value of non-hedging derivatives on commodities, also including the effects of settlements, are recognized in the profit and loss account item "Other operating income (expense)".

F-13

##### Table of Contents

delivery of the asset within the time frame generally established by regulation or convention in the marketplace concerned, the transaction is accounted for on the settlement date.

Receivables are measured at amortized cost (see item "Financial fixed assets" below).

Transferred financial assets are derecognized when the contractual rights to receive the cash flows of the financial assets are transferred together with the risks and rewards of the ownership.

Inventories, including compulsory stocks and excluding contract work in progress, are stated at the lower of purchase or production cost and net realizable value. Net realizable value is the estimated selling price less the costs to sell, or, with reference to inventories of crude oil and petroleum products already included in binding sale contracts, the contractual sale price. Inventories of natural gas which are principally acquired with the purpose of selling in the near future and generating a profit from fluctuations in price are measured at fair value less costs to sell.

The cost for 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, or monthly, when it is justified by the use and the turnover of inventories of crude oil and petroleum products; the cost for inventories of the Petrochemical segment is determined by applying the weighted-average cost on an annual basis.

Contract work in progress is measured using the cost-to-cost method whereby contract revenue is recognized based on the stage of completion as determined by the cost incurred. Advances are deducted from inventories within the limits of contractual considerations; any excess of such advances over the value of the inventories is recorded as a liability. Losses related to construction contracts are recognized immediately as an expense when it is probable that total contract costs will exceed total contract revenues. Contract work in progress not yet invoiced, whose payment will be made in a foreign currency, is translated to euro using the current exchange rates at year end and the effect of rate changes is reflected in the profit and loss account.

When take-or-pay clauses are included in long-term natural gas purchase contracts, uncollected gas volumes which imply the "pay" clause, measured using the price formulas contractually defined, are recognized under "Other assets" as "Deferred costs" as an offset to "Other payables" or, after the settlement, to "Cash and Cash equivalents". The allocated deferred costs are charged to the profit and loss account: (i) when natural gas is actually delivered – the related cost is included in the determination of the weighted-average cost of inventories; and (ii) for the portion which is not recoverable, when it is not possible to collect gas that was previously uncollected within the contractually defined deadlines. Furthermore, the allocated deferred costs are tested for economic recoverability by comparing the related carrying amount and their net realizable value, measured adopting the same criteria described for inventories.

Hedging instruments are described in the section "Derivative Instruments".

Non-current assets

Property, plant and equipment4
Tangible assets, including investment properties, are recognized using the cost model and stated at their purchase or self-construction cost including any costs directly attributable to bringing the asset into operation. In addition, when a substantial period of time is required to make the asset ready for use, the purchase price or self-construction cost includes the borrowing costs incurred that could have otherwise been saved had the investment not been made.

In the case of a present obligation for the dismantling and removal of assets and the restoration of sites, the carrying value includes, with a corresponding entry to a specific provision, the estimated (discounted) costs to be incurred at the moment the asset is retired. Changes in estimate of the carrying amounts of provisions due to the passage of time and changes in discount rates are recognized under "Provisions for contingencies"5.

Property, plant and equipment is not revalued for financial reporting purposes.

(4) |  | Recognition and evaluation criteria of exploration and production activities are described in the section "Exploration and production activities" below.
(5) |  | 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 are generally recognized, as undetermined settlement dates for asset retirements do not allow a reasonable estimate of the fair value of the associated 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.

Assets carried under financial leasing or concerning arrangements that do not take the legal form of a finance lease but substantially transfer all the risks and rewards of ownership of the leased asset are recognized at fair value, net of taxes due from the lessor or, if lower, at the present value of the minimum lease payments. Leased assets are included within property, plant and equipment. A corresponding financial debt payable to the lessor is recognized as a financial liability. These assets are depreciated using the criteria described below. When the renewal is not reasonably certain, leased assets are depreciated over the shorter of the lease term or the estimated useful life of the asset. Expenditures on renewals, improvements and transformations which provide additional economic benefits are capitalized to property, plant and equipment. Tangible assets, from the moment they begin or should begin to be used, are depreciated systematically using a straight-line method over their useful life6 which is an estimate of the period over which the assets will be used by the company. When tangible assets are composed of more than one significant element with different useful lives, each component is depreciated separately. The amount to be depreciated is the book value less the estimated net realizable value at the end of the useful life, if it is significant and can be reasonably determined. Land is not depreciated, even when purchased with a building. Tangible assets held for sale are not depreciated (see item "Non-current assets held for sale" below). Assets that can be used free of charge by third parties are depreciated over the shorter term of the duration of the concession or the asset’s useful life. Replacement costs 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. Expenditures for ordinary maintenance and repairs are expensed as incurred. The carrying value of property, plant and equipment is reviewed for impairment whenever events indicate that the carrying amounts for those assets may not be recoverable. The recoverability of an asset is assessed by comparing its carrying value with the recoverable amount, which is the higher of fair value less costs to sell or its value in use. If there is no 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 the asset. Value in use is the present value of the future cash flows expected to be derived 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 remaining useful life of the asset, giving more importance to independent assumptions. Oil, natural gas and petroleum products prices (and to prices for products which derive there from) used to quantify the expected future cash flows are estimated based on forward prices prevailing in the marketplace for the first four years and management’s long-term planning assumptions thereafter. Discounting is carried out at a rate that reflects a current market valuation of the time value of money and of those specific risks of the asset that are not reflected in the estimate of the future cash flows. In particular, the discount rate used is the Weighted Average Cost of Capital (WACC) adjusted for the specific country risk of the activity. The evaluation of the specific country risk to be included in the discount rate is provided by external parties. The WACC differs considering the risk associated with individual operating segments; in particular for the assets belonging to the Gas & Power and Engineering & Construction segments, taking into account the different risk compared with Eni, specific WACC rates have been defined (for Gas & Power segment on the basis of a sample of companies operating in the same segment; for Engineering & Construction segment on the basis of the market quotation); WACC used for impairments in the Gas & Power segment is adjusted to take into consideration the risk premium of the specific country of the activity while WACC used for impairments in the Engineering & Construction segment is not adjusted for country risk as most of the company assets are not located in a specific country. For the regulated activities, the discount rate used for the measurement of the value in use is equal to the rate return defined by the Regulator. For the other segments, a single WACC is used considering that the risk is the same to that of Eni as a whole. Value in use is calculated net of the tax effect as this method results in values similar to those resulting from discounting pre-tax cash flows at a pre-tax discount rate deriving, through an iteration process, from a post-tax valuation. 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 makes a reversal that is recognized in the profit or loss account as income from asset revaluation. This reversed amount cannot exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years.

Intangible assets
Intangible assets are assets without physical substance, controlled by the company and able to produce future economic benefits, and goodwill acquired in business combinations. An asset is classified as intangible when management is able to distinguish it clearly from goodwill. This condition is normally met when: (i) the intangible

(6) |  | With reference to the preparation of the Consolidated Financial Statements 2010, prospectively starting from January 1, 2010, management has reviewed: (i) the useful life of pipelines (from 40 to 50 years), consistently with the review made by the Electricity and Gas Authority for tariff purposes. The positive impact on annual results has been euro 31 million (gross of taxes); and (ii) the residual useful lives of refineries and related facilities due to a change in the expected pattern of consumption of the expected future economic benefit embodied in those assets. In doing so, the Company has aligned with practices prevailing among integrated oil companies, particularly the European companies. Management’s conclusions have been supported by an independent technical review. The positive impact on annual results has been euro 76 million (gross of taxes).

asset arises from contractual or legal rights, 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 generated by the underlying asset and to restrict the access of others to those cash flows.

Intangible assets are initially stated at cost as determined by the criteria used for tangible assets and they are not revalued for financial reporting purposes.

Intangible assets with a definite useful life are amortized systematically over their useful life estimated as the period over which the assets will be used by the company; the amount to be amortized and the recoverability of the carrying amount are verified in accordance with the criteria described in the section "Property, plant and equipment".

Goodwill and other intangible assets with an indefinite useful life are not amortized. The recoverability of their carrying value is reviewed at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Goodwill is tested for impairment at the level of the smallest aggregate on which the company, directly or indirectly, evaluates the return on the capital expenditure to which goodwill relates. When the carrying amount of the cash-generating unit, including goodwill allocated thereto, exceeds the cash-generating unit’s recoverable amount7, the excess is recognized as impairment. The impairment loss is first allocated to reduce the carrying amount of goodwill; any remaining excess to be allocated to the assets of the unit is applied pro-rata on the basis of the carrying amount of each asset in the unit. Impairment charges against goodwill are not reversed8.

Costs of technological development activities are capitalized when: (i) the cost attributable to the development activity 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 demonstrated that the asset is able to generate future economic benefits.

Intangible assets also include public to private service concession arrangements concerning the development, financing, operation and maintenance of infrastructures under concession, in which: (i) the grantor controls or regulates what services the operator must provide with the infrastructure, and at what price; and (ii) the grantor controls – by the ownership, beneficial entitlement or otherwise – any significant residual interest in the infrastructure at the end of the concession arrangement.

According to the agreements, the operator has the right to operate the infrastructure, controlled by the grantor, in order to provide the public service9.

Exploration and production activities10 11

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 UOP basis, as detailed in the section "Development", considering both developed and undeveloped reserves. Expenditures associated with possible and probable reserves

(7) |  | For the definition of recoverable amount see item "Property, plant and equipment".
(8) |  | Impairment charges recognized in an interim period are not reversed also when, considering conditions existing in a subsequent interim period, they would have been recognized in a smaller amount or would not have been recognized.
(9) |  | When the operator has an unconditional contractual right to receive cash or another financial asset from or at the direction of the grantor, considerations received or receivable by the operator for construction or upgrade of infrastructure are recognized as a financial asset.
(10) |  | IFRS does not have specific criteria for hydrocarbon exploration and production activities. Eni continues to use existing accounting policies for exploration and evaluation of assets previously applied before the introduction of IFRS 6 "Exploration for and evaluation of mineral resources".
(11) |  | With reference to the preparation of the Consolidated Financial Statements 2010, prospectively starting from April 1, 2010, Eni has updated the natural gas conversion factor from 5,742 to 5,550 standard cubic feet of gas per barrel of oil equivalent. This update reflected changes in Eni’s gas properties that took place in recent years and was assessed by collecting data on the heating power of gas in all Eni’s 230 gas fields on stream at the end of 2009. Therefore, starting from second quarter 2010, UOP depreciation rate for oil and gas assets is defined considering productions and reserves determined using updated gas conversion factor to oil and gas joint production reservoirs. The effect of this update on production expressed in boe was 26 KBOE/d for the full year 2010. Other per boe indicators were only marginally affected by the update (e.g. realization prices, costs per boe) and also negligible was the impact on depletion charges. Other oil companies may use different conversion rates.

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 initially capitalized in order to reflect their nature as an investment and subsequently 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 within property, plant and equipment 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 at 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 investments and proved developed reserves. 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
Oil and gas reserves related to production-sharing agreements and buy-back contracts are determined on the basis of contractual clauses related to the repayment of costs incurred for the exploration, development and production activities executed through the use of company’s technologies and financing (cost oil) and the company’s share of production volumes not destined to cost recovery (profit oil). Revenues from the sale of the production entitlements against both cost oil and profit oil are accounted for on an accrual basis whilst exploration, development and production costs are accounted for according to the policies mentioned above. The company’s share of production volumes and reserves representing the profit oil includes the share of hydrocarbons which corresponds to the taxes to be paid, according to the contractual agreement, by the national government on the behalf of the company. As a consequence the company has to recognise at the same time an increase in the taxable profit, through the increase of the revenues, and a tax expense.

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 "Property, plant and equipment".

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 government 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, jointly controlled entities and associates are accounted for using the equity method12. When there is objective evidence of impairment (see also section "Current assets"), the recoverability is tested by comparing the carrying amount and the related recoverable amount determined by adopting the criteria indicated in the section "Property, plant and equipment".

(12) |  | In the case of step acquisition of a significant influence (or joint control), the investment is recognized at the acquisition date of significant influence (joint control) at the amount deriving from the use of the equity method assuming the adoption of this method since initial acquisition; the "step-up" of the carrying amount of interests owned before the acquisition of significant influence (joint control) is taken to equity.

F-17

##### Table of Contents

Subsidiaries, joint ventures and associates excluded from consolidation are accounted for at cost, adjusted for impairment losses if this does not result in a misrepresentation of the company’s financial condition. When the reasons for their impairment cease to exist, investments accounted for at cost are re-valued within the limit of the impairment made and their effects are included in "Other income (expense) from investments".

Other investments, included in non-current assets, are recognized at their fair value and their effects are included in the equity reserve related to other comprehensive income; the changes in fair value recognized in equity are charged to the profit and loss account when it is impaired or realized. When investments are not traded in a public market and fair value cannot be reasonably determined, investments are accounted for at cost, adjusted for impairment losses; impairment losses may not be reversed13.

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 to 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 adjusted to take into account capital repayments, devaluations and amortization of the difference between the reimbursement value and the initial carrying value. Amortization is carried out on the basis of the effective interest 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"). Receivables for finance leases are recognized at an amount equal to the present value of the lease payments and the purchase option price or any residual value; the amount is discounted at the interest rate implicit in the lease.

Any impairment is recognized by comparing the carrying value with the present value of the expected cash flows discounted at the effective interest rate as defined at initial recognition, or at the moment of its updating to reflect re-pricings contractually established.

Receivables and financial assets to be held to maturity are recognized net of the allowance for impairment losses; when the impairment loss is definite the allowance for impairment losses is reversed for excess charges. Changes to the carrying amount of receivables or financial assets in accordance with the amortized cost method are recognized as "Financial income (expense)".

Non-current assets held for sale
Non-current assets and current and non-current assets included within disposal groups, whose carrying amount will be recovered principally through a sale transaction rather than through their continuing use, are classified as held for sale.

Non-current assets held for sale, current and non-current assets included within disposal groups that have been classified as held for sale and the liabilities directly associated with them are recognized in the balance sheet separately from the entity’s other assets and liabilities.

Non-current assets held for sale are not depreciated and they are measured at the lower of the fair value less costs to sell or their carrying amount.

Any difference between the carrying amount and the fair value less costs to sell is taken to the profit or loss account as an impairment loss; any subsequent reversal is recognized up to the cumulative impairment losses, including those recognized prior to qualification of the asset as held for sale.

Financial liabilities
Debt is measured at amortized cost (see item "Financial fixed assets" above).

(13) |  | Impairment charges recognized in an interim period are not reversed also when, considering conditions existing in a subsequent interim period, they would have been recognized in a smaller amount or would not have been recognized.

Provisions for contingencies
Provisions for contingencies are liabilities for risks and charges of a definite nature and whose existence is certain or probable but for which at year-end the timing or amount of future expenditure is uncertain. Provisions are recognized when: (i) there is a current obligation (legal or constructive), as a result of a past event; (ii) it is probable that the settlement of that obligation will result in an outflow of resources embodying economic benefits; and (iii) the amount of the obligation can be reliably estimated. The amount recognized as a provision is the best estimate of the expenditure required to settle the present obligation at the balance sheet date or to transfer it to third parties at that time. The amount recognized for onerous contracts is the lower of the cost necessary to fulfill the obligations, net of expected economic benefits deriving from the contracts, and any indemnity or penalty arising from failure to fulfill these obligations. If the effect of the time value is material, and the payment date of the obligations can be reasonably estimated, provisions to be accrued are the present value of the expenditures expected to be required to settle the obligation at a discount rate that reflects the company’s average borrowing rate taking into account the risks associated with the obligation. The increase in the provision due to the passage of time is recognized as "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. Charges to the profit and loss account are made with the amortization process.

Costs that the company expects to bear in order to carry out restructuring plans are recognized when 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, including constructive obligations, are classified as either defined contribution plans or defined benefit plans depending on the economic substance of the plan as derived from its principal terms and conditions. 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 plans, net of any plan assets, are determined on the basis of actuarial assumptions and charged on an accrual basis during the employment period required to obtain the benefits.

The actuarial gains and losses of defined benefit plans are recognized pro-rata on service, in the profit and loss account using the corridor method, if and to the extent that net cumulative unrecognized actuarial gains and losses at the end of the previous reporting period exceed the greater of 10% of the present value of the defined benefit obligation or 10% of the fair value of the plan assets, over the expected average remaining working lives of the employees participating in the plan. Such actuarial gains and losses derive from changes in the actuarial assumptions used or from a change in the conditions of the plan. 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 taken to the profit or loss in their entirety.

Treasury shares
Treasury shares are recorded at cost and as a reduction of equity. Gains resulting from subsequent sales are recorded in equity.

Revenues and costs
Revenues associated with sales of products and services are recorded when significant risks and rewards of ownership pass to the customer or when the transaction can be considered settled and the associated revenue can be reliably measured. In particular, revenues are recognized for the sale of:

• |  | crude oil, generally upon shipment;

• |  | natural gas, upon delivery to the customer;
• |  | petroleum products sold to retail distribution networks, generally upon delivery to the service stations, whereas all other sales of petroleum products are generally recognized upon shipment;
• |  | chemical products and other products, generally upon shipment.

Revenues are recognized upon shipment when, at that date, significant risks are transferred to the buyer.

Revenues from crude oil and natural gas production from properties in which Eni has an interest together with other producers are recognized on the basis of Eni’s net 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 year end.

Income related to partially rendered services is recognized in the measurement of accrued income if the stage of completion can be reliably determined and there is no significant uncertainty as to the collectability of the amount and the related costs. When the outcome of the transaction cannot be estimated reliably, revenue is recognized only to the extent of the expenses recognized that are recoverable.

Revenues accrued during the year related to construction contracts are recognized on the basis of contractual revenues with reference to the stage of completion of a contract measured on the cost-to-cost basis. For service concession arrangements (see item "Intangible assets" above) in which customers fees do not provide a reliable distinction between the compensation for construction/update of the infrastructure and the compensation for operating it and in the absence of external benchmarks, revenues recognized during the construction phase are limited to the amount of the costs incurred.

Additional revenues, derived from a change in the scope of 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 from additional costs incurred for reasons attributable to the client are included in the total amount of revenues when it is probable that the counterparty will accept them. Tangible assets, different from an infrastructure used in service concession arrangements, transferred from customers (or constructed using cash transferred from customers) and used to connect them to a network to supply goods and services, are recognized at their fair value as an offset to revenues. When more than one separately identifiable service is provided (for example, connection to a network and supply of goods) the entity shall assess for which one service it receives the transferred asset from the customer and it shall consistently recognize a revenue when the connection is delivered or over the lesser period between the length of the supply and the useful life of the transferred asset.

Revenues are stated net of returns, discounts, rebates, bonuses and direct taxation.

Award credits, related to customer loyalty programs, are recognized as a separate component of the sales transaction which grant the right to customers. Therefore, the portion of revenues related to the fair value of award credits granted is recognized as an offset to the item "Other liabilities". The liability is charged to the profit and loss account in the period in which the award credits are redeemed by customers or the related right is lost.

The exchange of goods and services of a similar nature and value do not give rise to revenues and costs as they do not represent sale transactions.

Costs are recorded when the related goods and services are sold, consumed or allocated, or when their future benefits cannot be determined.

Costs associated with emission quotas, determined on the basis of the average prices of the main European markets at period end, are reported in relation to the amount of the carbon dioxide emissions that exceed the amount assigned. Costs related to the purchase of the emission rights are recorded as intangible assets net of any negative difference between the amount of emissions and the quotas assigned. Revenues related to emission quotas are recognized when they are realized for the related sale. In case of sale, if applicable, the acquired emission rights are considered as the first to be sold. Monetary receivables granted as a substitution of emission rights awarded free of charge are recognized as an offset to item "Other income" of the profit and loss account.

F-20

##### Table of Contents

Operating lease payments are recognized in the profit and loss account over the length of the contract.

Labor costs include stock options granted to managers, consistent with their actual remunerative nature. The instruments granted are recorded at fair value on the vesting date and are not subject to subsequent adjustments; the current portion is calculated pro-rata over the vesting period14. The fair value of stock options is determined using valuation techniques which consider conditions related to the exercise of options, current share prices, expected volatility and the risk-free interest rate. The fair value of stock options is recorded as a charge 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 incurred for other scientific research activities or technological development, which cannot be capitalized, are included in the profit and loss account.

Exchange rate differences
Revenues and costs associated with transactions in currencies other than the functional currency are translated into the functional currency by applying the exchange rate at the date of the transaction.

Monetary assets and liabilities denominated in currencies other than 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 denominated in currencies other than the functional currency valued at cost are translated at the initial exchange rate. Non-monetary assets that are re-measured to fair value, recoverable amount or realizable value are translated at the exchange rate applicable at the date of re-measurement.

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 included in "Income taxes payables". Current income tax assets and liabilities are measured at the amount expected to be paid to (recovered from) the tax authorities, using tax laws that have been enacted or substantively enacted as of the balance sheet date and the tax rates estimated on annual basis.

Deferred tax assets or liabilities are provided on temporary differences arising between the carrying amounts of the assets and liabilities and their tax bases, based on tax rates (tax laws) that have been enacted or substantively enacted for future years. Deferred tax assets are recognized when their realization is considered probable.

Relating to the temporary differences associated with investments in subsidiaries, associates and jointly controlled entities, the related deferred tax liabilities are not recognized if the investor is able to control the timing of reversal of the temporary differences and it is probable that the temporary difference will not reverse in the foreseeable future.

Deferred tax assets and liabilities are included in 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 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". When there is objective evidence that an impairment loss has occurred for reasons different from fair value decreases (see "Current assets" paragraph) derivative are recognized net of the allowance for impairment losses.

Derivatives are designated as hedging instruments when the relationship between the derivative and the hedged item is formally documented and the hedge is highly effective and regularly reviewed. 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 equity and then recognized in the profit and loss account consistent 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 for hedge accounting are reported in the profit and loss account.

Economic effects of transactions, which relate to purchase or sales contracts for commodities entered into to meet the entity’s normal operating requirements and for which the settlement is provided with the delivery of the goods, are recognized on an accrual basis (the so-called normal sale and normal purchase exemption or own use exemption).

Financial statements15
Assets and liabilities on the balance sheet are classified as current16 and non-current. Items on the profit and loss account are presented by nature17.

The statement of comprehensive income shows net profit integrated with income and expenses that are recognized directly in equity according to IFRS.

The statement of changes in shareholders’ equity includes profit and loss for the year, transactions with shareholders and other changes in shareholders’ equity.

The statement of cash flows is presented using the indirect method, whereby net profit is adjusted for the effects of non-cash transactions.

4 Changes in accounting principles
There are no changes in accounting principles to those applied in 2009.

5 Use of accounting estimates
The preparation of the Consolidated Financial Statements requires the use of estimates and assumptions that affect the assets, liabilities, revenues and expenses reported in the financial statements, as well as amounts included in the notes thereto, including discussion and disclosure of contingent liabilities. Estimates made are based on complex or subjective judgments and past experience of other assumptions deemed reasonable in consideration of the information available at the time. The accounting policies and areas that require the most significant judgments and estimates to be used in the preparation of the Consolidated Financial Statements are in relation to the accounting for oil and natural gas activities, specifically in the determination of proved and proved developed reserves, impairment of fixed assets, intangible assets and goodwill, asset retirement obligations, business combinations, pensions and other post-retirement benefits, recognition of environmental liabilities and recognition of revenues in the oilfield services construction and engineering businesses. Although the company uses its best estimates and

(15) |  | The financial statements are the same reported in the Annual Report 2009 with the exception of the cash flow statement that has been updated, consistently with the statement presented by the main competitors, in order to provide a different articulation of the items included in the "Net cash provided from operating activities". In particular, the main changes concerned: (i) the elimination of the items "Cash generated from operating profit before changes in working capital" and "Cash from operations"; (ii) the addition of the item "Share of profit (loss) of equity-accounted investments"; (iii) the inclusion in the item "Changes in working capital" of the net impairments (reversals) related to inventories, trade receivables and change in the fair value of derivatives, previously included in the item "Revaluations, net"; (iv) the inclusion in the item related to "Changes in working capital" of changes of provisions for contingencies; and (v) the presentation of the change in the provisions for employee benefits after the "new" item which includes the "Cash flow from changes in working capital".

##### Table of Contents

judgments, actual results could differ from the estimates and assumptions used. A summary of significant estimates follows.

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 that can be economically producible with reasonable certainty from known reservoirs under existing economic conditions and operating methods. 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, 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 are classified as proved undeveloped. Volumes are subsequently reclassified from proved undeveloped to proved developed as a consequence of development activity. The first proved developed bookings 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. Eni reassesses its estimate of proved reserves periodically. The estimated proved reserves of oil and natural gas may be subject to future revision and upward and downward revision may be made to the initial booking of 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 in regards to 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 as that ultimately will be recovered. Oil and natural gas reserves have a direct impact on certain amounts reported in the Consolidated 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 for each field decreases depreciation, depletion and amortization expense. Conversely, 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 or not property impairment is to be carried out. The larger the volume of estimated reserves, the lower the likelihood of asset impairment.

Impairment of assets
Eni assesses its tangible assets and intangible assets, including goodwill, for possible impairment if there are events or changes in circumstances that indicate 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, a reduced utilization of the plants and, for oil and gas properties, significant downward revisions of estimated proved reserve quantities or significant increase of the estimated development costs. 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. Similar remarks are valid for the physical recoverability of assets recognized in the balance sheet (deferred cost – see Note 20) related to natural gas volumes not collected under long-term purchase contracts with take-or-pay clauses.

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 cost or the 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 analyses 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.

For oil and natural gas properties, the expected future cash flows are estimated principally 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. Oil, natural gas and petroleum product prices (and prices from products which

F-23

##### Table of Contents

are derived there from) used to quantify the expected future cash flows are estimated based on forward prices prevailing in the marketplace for the first four years and management’s long-term planning assumptions thereafter. The estimate of the future amount of production is based on assumptions related to the commodity future prices, lifting and development costs, market demand and other factors. The discount rate reflects the current market valuation of the time value of money and of the specific risks of the asset not reflected in the estimate of the future cash flows. Goodwill and other intangible assets with an indefinite useful life are not subject to amortization. The company tests such assets at the cash-generating unit level for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount. 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 recoverable amount 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 to remove tangible equipment and restore land or seabed require significant estimates in calculating the amount of the obligation and determining the amount required to be recorded presently in the Consolidated Financial Statements.

Estimating future asset retirement obligations is complex. It requires management to make estimates and judgments with respect to removal obligations that will come to term many years into the future and contracts and regulations are often unclear as to what constitutes removal. In addition, the ultimate financial impact of environmental laws and regulations is not always clearly known as asset removal technologies and costs constantly evolve in the countries where Eni operates, as do political, environmental, safety and public expectations. 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 obligation 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 (i.e. interest accretion) and any change in the estimates following the modification of future cash flows and discount rate adopted. The recognized asset retirement obligations are based on 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 business combinations requires the allocation of the purchase price to the various assets and liabilities of the acquired business at their respective fair values. Any positive residual difference is recognized as "Goodwill". Negative residual differences are credited to 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, production and other activities. They include legislations that implement 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. Management, considering the actions already taken, insurance policies obtained 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. However, 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 an unknown contamination; (ii) the results of the ongoing surveys and other possible effects of statements required by Decree No. 471/1999 of the Ministry for the Environment concerning the remediation of contaminated sites; (iii) the possible effects of future environmental legislations and rules; (iv) the effects of possible technological changes relating to future remediation; and (v) the possibility of litigation and the difficulty of determining Eni’s liability, if any, against other potentially responsible parties with respect to such litigations and the possible insurance recoveries.

Employee benefits
Defined benefit plans 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 trends, estimated retirement dates and mortality rates. The significant assumptions used to account for defined benefit plans 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. Indicators used in selecting the discount rate include rates of annuity contracts and rates of return on high quality fixed-income investments. 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 individual employees involved, based principally on available actuarial data; and (v) determination of the 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 unrecognized actuarial gains and losses 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 the profit or loss in their entirety.

Contingencies
In addition to accruing the estimated costs for environmental liabilities, asset retirement obligation and employee benefits, Eni accrues for all contingencies that are both probable and estimable. These other contingencies are primarily related to litigation and tax issues. Determining the appropriate amount to accrue is a complex estimation process that includes subjective judgments.

Revenue recognition in the Engineering & Construction segment
Revenue recognition in the Engineering & Construction 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 the geographical region, market conditions in that region and any assessment that is necessary to estimate with sufficient precision the total future costs as well as the expected timetable. Additional income is derived from a change in the scope of work is included in the total amount of revenues when it is probable that the customer will approve the variation and the related amount. Claims deriving from additional costs incurred for reasons attributable to the client are included in the total amount of revenues when it is probable that the counterparty will accept them.

6 Recent accounting principles

Accounting standards and interpretations issued by IASB /IFRIC and endorsed by EU
By Commission Regulation No. 632/2010 of July 19, 2010 the revised IAS 24 "Related Party Disclosures" has been endorsed. The standard: (i) enhances the definition of a related party requiring new cases; and (ii) for transactions between entities related to the same Government, allows to limit quantitative disclosures to significant transactions.

In particular, equity instruments issued to extinguish a liability in full or in part, are measured at their fair value or, if fair value cannot be reliably measured, at the fair value of the financial liability extinguished. The difference between the carrying amount of the financial liability extinguished and the fair value of equity instruments issued shall be recognized in the profit or loss account. IFRIC 19 provisions shall be applied for annual periods beginning on or after July 1, 2010 (for Eni: 2011 financial statements).

By Commission Regulation No. 149/2011 of February 18, 2011, "Improvements to IFRSs" have been endorsed. The document includes only changes to the existing standards and interpretation with a technical and editorial nature. The provisions come into effect starting from 2011.

Accounting standards and interpretations issued by IASB/IFRIC and not yet been endorsed by EU
On November 12, 2009 IASB issued IFRS 9 "Financial Instruments" which changes recognition and measurement criteria of financial assets and their classification in the financial statements. In particular, new provisions require, inter alia, a classification and measurement model of financial assets based exclusively on the following categories: (i) financial assets measured at amortized cost; and (ii) financial assets measured at fair value. New provisions also require that investments in equity instruments, other than subsidiaries, jointly controlled entities or associates, shall be measured at fair value with effects taken to the profit and loss account. If these investments are not held for trading purposes, subsequent changes in the fair value can be recognized in other comprehensive income, even if dividends are taken to the profit and loss account. Amounts taken to other comprehensive income shall not be subsequently transferred to the profit or loss account even at disposal. In addition, on October 28, 2010 the IASB added to IFRS 9 the requirements on the accounting for financial liabilities. In particular, new provisions require, inter alia, that if a financial liability is measured at fair value through profit or loss, subsequent changes in the fair value attributable to changes in the own credit risk shall be presented in the other comprehensive income; the component related to own credit risk is recognized in profit and loss account if the treatment of the changes in own credit risk would create or enlarge an accounting mismatch. IFRS 9 provisions shall be applied for annual periods beginning on or after January 1, 2013.

On October 7, 2010 the IASB issued Amendment to IFRS 7 "Disclosures - Transfers of financial assets", that provides supplementary disclosures on financial instruments, with reference to transfers of financial assets, to describe any risks that may remain with the entity that transferred the assets. The amendments also require additional disclosures if a disproportionate amount of transfer transactions are undertaken around the end of a reporting period. New provisions shall be applied for annual periods beginning on or after July 1, 2011 (for Eni: 2012 financial statements).

Eni is currently reviewing these new IFRS and interpretations to determine the likely impact on the Group’s results.

Therefore, such derivatives were not related to specific trade or financing transactions.

##### Table of Contents

Fair value of cash flow hedge derivatives of euro 210 million (euro 236 million at December 31, 2009) essentially pertained to the Gas & Power segment (euro 209 million). These derivatives were designated to hedge surpluses or deficits of gas to achieve a proper balance in the gas portfolio. Other commodity derivatives were entered into to hedge variability in future cash flows on highly probable future sale transactions or on already contracted sales due to different movements in commodity prices as sales prices can be indexed to spot market benchmarks quoted on continental hub, whereas purchase costs are indexed to the price of oil and products. A similar scheme applies to exchange rate hedging derivatives.

Negative fair value of contracts expiring by 2011 is given in Note 25 – Other current liabilities; positive and negative fair value of contracts expiring beyond 2011 is given in Note 20 – Other non-current receivables and in Note 30 – Other non-current liabilities. The effects of the evaluation at fair value of cash flow hedge derivatives are given in the Note 32 – Shareholders’ equity and in the Note 36 – Finance income (expense).

The nominal value of cash flow hedge derivatives for purchase and sale commitments was euro 1,145 million and euro 273 million, respectively.

Information on the hedged risks and the hedging policies is given in Note 34 – Guarantees, commitments and risks – Risk factors.

Other assets amounted to euro 514 million (euro 373 million at December 31, 2009) and included prepayments and accrued income for euro 155 million (euro 104 million at December 31, 2009), insurance premiums for euro 52 million (euro 18 million at December 31, 2009) and rentals for euro 20 million (euro 35 million at December 31, 2009).

In assessing whether impairment is required, the carrying value of an asset, item of property, plant and equipment, is compared with its recoverable amount. The recoverable amount is the higher of the asset’s fair value less costs to sell and value in use. Given the nature of Eni’s activities, information on the fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers are in place. Eni assesses individual assets or groups of assets (Cash Generating Units - CGUs) which represent the lowest level at which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. The Group’s main CGUs are: (i) in the Exploration & Production segment, individual oilfields or pools of oilfields whereby technical, economic or contractual features make the underlying cash flows interdependent; (ii) in the Gas & Power segment, transport and distribution networks and related facilities, storage sites and re-gasification facilities in a consistent way with the gas segments of operations that are defined by Regulatory Authorities for the purpose of tariff settings. Other CGUs in the Gas & Power segment are gas carrier ships and plants for the production of electricity; (iii) in the Refining & Marketing segment, refining plants and commercial facilities relating to each distribution channels and by country (ordinary network, high-ways network, and wholesale activity); (iv) in the Petrochemical segment, production plants by business and related facilities; and (v) in the Engineering & Construction segment, the Business Units Offshore and Onshore constructions, Onshore drilling facilities and individual Rigs for Offshore operations. The recoverable amount is calculated by discounting the estimated cash flows deriving from the use of the CGU and, if significant and reasonably determinable, the cash flows deriving from its disposal at the end of its useful life. Recoverable amounts of the CGUs in the regulated businesses of gas transportation, distribution, storage and re-gasification equal their respective net borrowings recognized by Regulatory Authority, considering that the operating cost structure borne is recognized in the tariff regime set by Regulatory Authority (Regulatory Asset Base - RAB).

Cash flows are determined on the basis of the best information available at the moment of the assessment deriving: (i) for the first four years of the projection, from the Company’s four-year plan approved by the top management which provides information on expected oil and gas production volumes, sales volumes, capital expenditures, operating costs and margins and industrial and marketing set-up, as well as trends on the main

F-33

macroeconomic variables, including inflation, nominal interest rates and exchange rates; (ii) for the subsequent years, considering management’s assumptions of long-term trends in the main macroeconomic variables (inflation rates, oil prices, etc.), cash flow projections are based on the following factors: (a) for the oil and gas CGUs, the residual life of the reserves and associated projections of operating costs and development expenditures; (b) for the CGUs of the Refining & Marketing segment, the economical and technical life of the plants and associated projections of operating costs, expenditures to support plant efficiency and refining and marketing margins; (c) for the CGUs of the Petrochemical segment, the economical and technical life of the plants and associated projections of expenditures to support plant efficiency, and normalized operating results plus depreciation (normalized EBITDA); (d) for the CGUs of the gas market and the Engineering & Construction segment, the perpetuity method of the last-year plan by using a nominal growth rate ranging from 0% to 2%; and (e) for the regulated businesses of gas transportation, distribution, storage and regasification, a terminal value equal to the regulatory asset base of the last-year plan; and (iii) the commodity prices have been assessed based on the forward prices prevailing in the marketplace as of the balance sheet date for the first four years of the cash flow projections and the long-term price assumptions adopted by the Company’s management for strategic planning purposes for the following years (see Note 3 – Summary of significant accounting policies).

Value-in-use is determined by discounting post-tax cash flows at the rate which corresponds for the Exploration & Production, Refining & Marketing and Petrochemical segments to the Company’s weighted average cost of capital, adjusted to consider risks specific to each country of activity (adjusted post-tax WACC). In 2010, the adjusted post-tax rates used for assessing value-in-use decreased by 0.5 percentage points on average from the previous year reflecting a reduced market premium for the equity risk and a slight decrease in the cost of borrowings to Eni following expected trends in the main market benchmarks. Such trends were partially offset by increased market yields on assets risk-free due to an higher risk premium for Italy. In 2010 the adjusted WACC used for impairment test purposes ranged from 8% to 13%.

Post-tax cash flows and discount rates were adopted as they resulted in an assessment that substantially approximated a pre-tax assessment.

In 2010, the Exploration & Production segment recorded immaterial asset impairments, if individually considered, for a total amount of euro 123 million which primarily related to gas properties located in USA and Egypt as a result of a changed price environment and downward reserve revisions, particularly associated to unproved properties.

Other impairments were recorded in both the Refining & Marketing and the Petrochemical segments as expenditures made in the year were entirely written off due to lack of economic perspectives associated with the relevant CGUs which were totally impaired in previous reporting periods.

Foreign currency translation differences of euro 2,614 million were primarily related to translation of entities accounts denominated in U.S. dollar (euro 2,221 million).

Other changes of euro 714 million included the initial recognition and change in the estimated amount of the costs for dismantling and restoring oil sites and expenditures associated with certain social projects of the Exploration & Production segment for euro 556 million, of which euro 287 million related to the recognition of social projects by Eni North Africa BV and the reclassification from assets held for sale following the decision of the proposed buyer not to acquire the 100% stake in the share capital of Società Adriatica Idrocarburi SpA for euro 292 million. The book value of assets disposed of amounted to euro 95 million.

Exploration expenditures of euro 538 million mainly related to license acquisition costs that are amortized on a straight-line basis over the contractual term of the exploration lease or fully written off against profit and loss upon expiration of terms or management’s decision to cease any exploration activities. Additions for the year included exploration drilling expenditures which were fully amortized as incurred for euro 1,009 million (euro 1,271 million at December 31, 2009).

Concessions, licenses, trademarks and similar items for euro 575 million primarily comprised transmission rights for natural gas imported from Algeria (euro 406 million) and concessions for mineral exploration (euro 121 million).

Service concession arrangements of euro 3,562 million primarily pertained to Italian gas distribution activity (euro 3,340 million and euro 3,492 million as of December 31, 2009 and 2010, respectively). Such activity is conducted in concession on the basis of municipal assignments, as the definition through relevant decrees of over-municipal minimum territorial reaches is still pending. At the expiration date of the concession, following the sale to a new operator of the gas distribution network, the outgoing operator is entitled to receive a reimbursement base on an industrial assessment of the relevant assets. Tariffs for the distribution service are defined by the Italian Authority for Electricity and Gas. Applicable regulations award concessions to distribution companies exclusively by means of competitive bid. Concessions are granted for a maximum term of 12 years. Government grants recorded as a decrease in the carrying amounts of service concession arrangements amounted to euro 729 million (euro 693 million as of December 31, 2009).

Other intangible assets with finite useful lives of euro 1,514 million primarily pertained to: (i) customer relationship and order backlog for euro 1,140 million (euro 1,244 million at December 31, 2009) recognized upon the business combination of Distrigas NV. These assets are amortized on the basis of the supply contract with the longest term (19 years) and the residual useful life of sale contracts (4 years); (ii) an option to develop offshore

Impairments of intangible assets with indefinite useful life (goodwill) of euro 430 million essentially pertained to the Gas & Power segment (euro 426 million), as described below. Change in the consolidation area of euro 173 million related to recognition of goodwill following the purchase price allocation in connection with the business combinations of Altergaz SA (euro 97 million) and Eni Mineralölhandel GmbH including its subsidiary Eni Marketing Austria GmbH (euro 76 million). More information is included in Note 33 – Other information – Main acquisitions.

The carrying amount of goodwill at the end of the year was euro 4,175 million (euro 4,410 million at December 31, 2009). The break-down by operating segment is as follows:

(euro million) |  | Dec. 31, 2009 |  | Dec. 31, 2010

Exploration & Production |  | 249 |  | 262

Goodwill acquired through business combinations has been allocated to the cash-generating units ("CGUs") that are expected to benefit from the synergies of the acquisition. The CGUs of the Gas & Power segment are composed of such commercial business units whose cash flows are interdependent and therefore benefit from acquisition synergies. The recoverable amounts of the CGUs are determined by discounting the future cash flows deriving from the continuing use of the CGUs and, if significant and reasonably determinable, the cash flows deriving from its disposal at the end of their useful lives. Recoverable amounts of the CGUs in the regulated businesses of gas transportation, distribution, storage and re-gasification equal their respective regulatory asset base, considering that the operating cost structure borne is recognized in the tariff regime set by Regulatory Authority (RAB - Regulatory Asset Base).

Cash flows are determined on the basis of the best information available at the moment of the assessment deriving: (i) for the first four years of the projection, from the Company’s four-year plan approved by the top management which provides information on expected oil and gas production volumes, sales volumes, capital expenditures, operating costs and margins and industrial and marketing set-up, as well as trends on the main macroeconomic variables, including inflation, nominal interest rates and exchange rates; (ii) for the subsequent years, considering management’s assumptions of long-term trends in the main macroeconomic variables (inflation rates, oil prices, etc.), cash flow projections are based on the following factors: (a) for the oil and gas CGUs, the residual life of the reserves and associated projections of operating costs and development expenditures; (b) for the CGUs of the Refining & Marketing segment, the economical and technical life of the plants and associated projections of operating costs, expenditures to support plant efficiency and refining and marketing margins; (c) for the CGUs of the gas market and the Engineering & Construction segment, the perpetuity method of the last-year plan by using a nominal growth rate ranging from 0% to 2%; and (d) for CGU of the regulated businesses of gas transportation - Italy, distribution, storage and re-gasification, a terminal value equal to the regulatory asset base of the last-year plan; and (iii) the commodity prices have been assessed based on the forward prices prevailing in the marketplace as of the balance sheet date for the first four years of the cash flow projections and the long-term price

assumptions adopted by the Company’s management for strategic planning purposes for the following years (see Note 3 – Summary of significant accounting policies).

Value-in-use is determined by discounting post-tax cash flows at the rate which corresponds: (i) for the Exploration & Production and Refining & Marketing segments to the Company’s weighted average cost of capital, adjusted to consider risks specific to each country of activity (adjusted post-tax WACC). In 2010, the adjusted post-tax rates used for assessing value-in-use decreased by 0.5 percentage points on average from the previous year reflecting a reduced market premium for the equity risk and a slight decrease in the cost of borrowings to Eni following expected trends in the main market benchmarks. Such trends were partially offset by increased market yields on assets risk-free due to an higher risk premium for Italy. In 2010 the adjusted WACC used for impairment test purposes ranged from 8% to 13%; (ii) the impairment test rate for the Gas & Power segment was estimated on the basis of a sample of comparable companies in the utility industry. The impairment test rate for the Engineering & Construction segment was derived from market data. Rates used in the Gas & Power segment were adjusted to take into consideration risks specific to each country of activity, while rates used in the Engineering & Construction segment did not reflect any country risks as most of the company assets are not permanently located in a specific country. Rates for the Gas & Power segment ranged from 7% to 8%, unchanged from the previous year as the decrease observed in the equity risks for gas companies was lower than the oil sector and was completely absorbed by the impact of rising yields on assets risk-free. In the Engineering & Construction segment, the discount rate was 9%, an increase of 0.5 percentage points from the previous year due to an higher equity risk and higher rates of risk-free assets; and (iii) for the regulated activities in the Italian natural gas sector, the discount rates were assumed to be equal to the rates of return defined by the Italian Authority for Electricity and Gas.

Post-tax cash flows and discount rates were adopted as they resulted in an assessment that substantially approximated a pre-tax assessment.

Goodwill has been allocated to the following CGUs:

Gas & Power segment

(euro million) |  | Dec. 31, 2009 |  | Dec. 31, 2010

Domestic gas market |  | 766 |  | 767
Foreign gas market |  | 2,247 |  | 1,918
- of which European market (Distrigas) |  | 2,148 |  | 1,722
Domestic natural gas transportation network |  | 305 |  | 305
Other |  | 10 |  | 10
|  | 3,328 |  | 3,000

Goodwill allocated to the CGU domestic gas market primarily pertained to goodwill recognized upon the buy-out of Italgas SpA minorities in 2003 through a public offering (euro 706 million). The relevant CGU is engaged in supplying gas to residential customers and small businesses. The impairment review performed at the balance sheet date confirmed the recoverability of the carrying amount of that CGU, including the allocated goodwill.

Goodwill allocated to the CGU European market pertained to goodwill recognized upon allocating the purchase price of the Distrigas business combination in 2009. The CGU comprises Distrigas marketing activities and those activities managed directly or indirectly by the Gas & Power division of the parent company Eni SpA, which includes marketing activities in Europe including France, Germany, Benelux, the UK, Switzerland and Austria. Those business units jointly benefited from the business combination synergies. In performing the impairment review of the recoverability of the CGU carrying amount at the balance sheet date, management recognized an impairment loss amounting to euro 426 million considering weak 2010 results and a reduced outlook for profitability.

The key assumptions adopted for determining future cash flow projections of both the CGUs Italian market and European market included marketing margins, forecast sales volumes, the discount rate and the growth rates adopted to determine the terminal value. Information on these drivers was derived from the four-year plan approved by the Company’s top management that was revised downwards with respect to past years future projections for returns and cash flows of the Company’s gas business, particularly the European market, due to expectations for weak demand and supply fundamentals, rising competitive pressures and increased commercial risk. The European market is expected to be negatively affected by lowering marketing margins over the next four years. This reflects ongoing development of very liquid spot markets for gas and the circumstance that spot prices have increasingly become the prevailing reference price for contractual formulae in supplies outside Italy whereas Eni’s purchase costs for gas are

mainly indexed to the price of oil and refined products. Trends in spot prices as compared to those in oil-linked purchase costs have been de-coupling until recently resulting in negative spreads during the course of 2010; management expects that those negative trends will re-couple in 2014 at the earliest. Compared to the previous year exercise of four-year financial projections, management is now assuming that the CGU European market will be affected by the following negative factors: (i) an average reduction of 47% in unit marketing margins that will be earned on future gas sales relating to determination of value in use of that CGU; (ii) an average reduction of 7% in planned sales volumes; and (iii) the discount rate and the growth rate are unchanged from previous assumptions. The industrial and financial forecasts for the next four-year plan of the gas business as well as the amount of the impairment loss recognized in 2010 consolidated accounts both take into consideration management assumptions to renegotiate better economic terms within the Company’s long-term gas purchase contracts, so as to restore the competitiveness of the Company’s cost position in the current depressed scenario for the gas sector. The renegotiation of revised contractual terms, including any price revisions and contractual flexibility, is established by such contractual clauses whereby parties are held to bring the contract back to the economic equilibrium in case of significant changes in the market environment, like the ones that have occurred since from the second half 2008. In the course of 2010, Eni has finalized a number of important contractual renegotiations by obtaining improved economic conditions for supplies and wider contractual flexibility with a benefit to its commercial programs. A number of renegotiations have been commenced or are due to commence in the near future involving all the Company’s main suppliers of gas based on long-term contracts. Should the outcome of those renegotiations fall short of management’s expectations and absent a solid recovery in fundamentals of the gas sector, management believes that future results of operations and cash flows of the Company’s gas business will be negatively affected with further consequences in terms of recoverability of the carrying amounts of the CGU European market.

The terminal value of the CGUs was estimated based on the perpetuity method of the last year of the plan assuming a long-term nominal growth rate equal to zero and 1.6% for the CGU Italian market and the CGU European market, respectively. Value in use of the CGU European market was assessed by discounting the associated post-tax cash flows at a post-tax rate of 7.5% that corresponds to the pre-tax rate of 9.3% (7.5% and 10%, respectively in the previous year). Value in use of the CGU Italian market was assessed by discounting the associated post-tax cash flows at a post-tax rate of 7% that corresponds to the pre-tax rate of 11.7% (7% and 11.9%, respectively in the previous year).

The excess of the recoverable amount of the CGU domestic gas market over its carrying amount including the allocated portion of goodwill (headroom) amounting to euro 344 million would be reduced to zero under each of the following alternative hypothesis: (i) a decrease of 26% on average in the projected commercial margins; (ii) a decrease of 26% on average in the projected sales volumes; (iii) an increase of 2.8 percentage points in the discount rate; and (iv) a negative nominal growth rate of 3.5%. The recoverable amount of the CGU and the relevant sensitivity analysis were calculated solely on the basis of retail margins, thus excluding wholesale and business client margins (industrial, thermoelectric and others).

Goodwill allocated to the domestic natural gas transportation network CGU was recognized alongside the repurchase of own shares by Snam Rete Gas SpA and equals the difference between the purchase cost over the carrying amount of the corresponding share of net equity. The recoverable amount of the CGU is assessed based on its Regulatory Asset Base (RAB) as recognized by the Italian Authority for Electricity and Gas and is higher than its carrying amount, including the allocated goodwill. Management believes that no reasonably possible change in the assumptions adopted would cause the headroom of the CGU to be reduced to zero.

The segment goodwill of euro 749 million was mainly recognized following the acquisition of Bouygues Offshore SA, now Saipem SA (euro 711 million) and allocated to the CGUs Offshore and Onshore. The impairment review performed at the balance sheet date confirmed the recoverability of the carrying amounts of both those CGUs, including the allocated portions of goodwill.

The key assumptions adopted for assessing the recoverable amounts of those two CGUs which exceed their respective carrying amounts related to operating results, the discount rate and the growth rates adopted to determine

the terminal value. Information on those drivers has been collected from the four-year plan approved by the Company’s top management, while the terminal value was estimated by using a perpetual nominal growth rate of 2% applied to the cash flow of the last year in the four-year plan. Value in use of both CGUs was assessed by discounting the associated post-tax cash flows at a post-tax rate of 9% (8.5% in 2009) which corresponds to the pre-tax rate of 11.8% and 13% for the Offshore business unit and the Onshore one respectively (10.8% and 12.3%, respectively in the previous year). The headroom of the Offshore business unit of euro 4,338 million would be reduced to zero under each of the following alternative changes in the above mentioned assumptions: (i) a decrease of 55% in the operating result of the four-year plan; (ii) an increase of about 9 percentage points of the discount rate; and (iii) negative real growth rate.

Changes in each of the assumptions that would cause the headroom of the Onshore business unit to be reduced to zero are greater than those of the Offshore construction CGU described above.

The Exploration & Production and the Refining & Marketing segments tested their goodwill, yielding the following results: (i) in the Exploration & Production segment with goodwill amounting to euro 262 million, management believes that there are no reasonably possible changes in the pricing environment and production/cost profiles that would cause the headroom of the relevant CGUs to be reduced to zero. Goodwill mainly refers to the portion of the purchase price that was not allocated to proved or unproved mineral interests of the business combinations Lasmo, Burren Energy (Congo) and First Calgary (Algeria) executed in previous reporting periods; and (ii) in the Refining & Marketing segment goodwill amounted to euro 164 million at the balance sheet date. Goodwill amounting to euro 66 million pertained to retail networks in the Czech Republic, Hungary and Slovakia which were purchased in 2008, for which the growth expectations improved in respect of the previous year following to a demand recovery and a better marketing position. Goodwill amounting to euro 76 million represented the allocation of the purchase price of a business combination involving a service station in Austria which was acquired in August 2010.

Fair value of the derivative contracts is determined using market quotations provided by primary info-provider, or in the absence of market information, appropriate valuation methods generally accepted in the marketplace.

Fair values of non-hedging derivatives of euro 420 million (euro 339 million at December 31, 2009) essentially consisted of derivative contracts that do not meet the formal criteria to be designated as hedges under IFRS because

F-47

##### Table of Contents

they were entered into in order to manage the net business exposures in foreign currency exchange rates, interest rates and commodity prices. Therefore, such derivatives were not related to specific trade or financing transactions.

Fair value of the cash flow hedge derivatives of euro 102 million (euro 129 million at December 31, 2009) referred to the Gas & Power segment. Further information on cash flow hedge derivatives is given in Note 13 – Other current assets. Fair value related to the contracts expiring beyond 2011 is given in Note 30 – Other non-current liabilities; fair value related to the contracts expiring in 2011 is indicated in Note 13 – Other assets and in Note 25 – Other current liabilities. The effects of the evaluation at fair value of cash flow hedge derivatives are given in Note 32 – Shareholders’ equity and in Note 36 – Operating expenses.

Nominal value of cash flow hedge derivatives for purchase and sale commitments was euro 775 million and euro 145 million, respectively.

Information on the hedged risks and the hedging policies is given in Note 34 – Guarantees, commitments – Risk factors.

Other asset of euro 1,624 million (euro 433 million at December 31, 2009) included prepayments amounting to euro 1,436 million that were made to gas suppliers upon triggering the take-or-pay clause provided by the relevant long-term arrangement. In accordance to those arrangements, the Company is contractually required to off-take minimum annual quantities of gas, or in case of failure is held to pay the whole price or a fraction for the uncollected volumes up to the minimum annual quantity. The Company is entitled to collect the pre-paid volumes in future years alongside the contract execution and for its entire duration or a shorter term as the case may be. The carrying amounts of those deferred costs, which are substantially equivalent to a receivable in-kind, are stated at the purchase cost or the net realizable value, whichever is lower. Prior-years impairment losses are reversed up to the purchase cost, whenever market conditions indicate that impairment no longer exits or may have decreased. In future years, management plans to recover the prepaid volumes by regaining market share and expanding its sales volumes in the European gas market leveraging on strengthening the Company’s market leadership and consolidating its customer base in the Italian market through effective marketing actions in both the retail market and the industrial and thermoelectric sector. Those action plans coupled with perspectives of steady long-term demand growth until 2020 will enable the Company to absorb volumes pre-paid during the market downturn. The industrial and financial forecasts for the next four-year plan of the gas business and beyond took into consideration management’s assumptions to renegotiate better economic terms within the Company’s long-term gas purchase contracts, so as to restore the competitiveness of the Company’s cost position in the current depressed scenario for the gas sector. The renegotiation of revised contractual terms, including any price revisions and contractual flexibility, is established by such contractual clauses whereby parties are held to bring the contract back to the economic equilibrium in case of significant changes in the market environment, like the ones that have occurred since the second half 2008. In the course of 2010, Eni has finalized a number of important contractual renegotiations by obtaining improved economic conditions for supplies and wider contractual flexibility with a benefit to its commercial programs. A number of renegotiations have commenced or are due to commence in the near future involving all the Company’s main suppliers of gas based on long-term contracts. Should the outcome of those renegotiations fall short of management’s expectations and absent a solid recovery in fundamentals of the gas sector, management believes that future results of operations and cash flows of the Company’s gas business will be negatively affected.

Fair value pertaining to the Gas & Power segment pertained to derivatives that were designated to hedge surpluses or deficits of gas to achieve a proper balance in the gas portfolio and hedge the exchange rate and commodity risk exposure as described in Note 13 – Other current assets. Fair value pertaining to the Exploration & Production segment pertained to future sale agreements of proved oil reserves due in 2011. Those derivatives were entered into to hedge exposure to variability in future cash flows deriving from the sale in the 2008-2011 period of approximately 2% of Eni’s proved reserves as of December 31, 2006, corresponding to 125.7 mmBBL, decreasing to 9 mmBBL as of December 31, 2010 due to transactions settled. Fair value of contracts expiring by 2010 is given in Note 13 – Other current assets; fair value of contracts expiring beyond 2010 is given in Note 30 – Other non-current liabilities and in Note 20 – Other non-current assets.

Long-term debt, including the current portion of long-term debt, of euro 21,268 million (euro 21,255 million at December 31, 2009) increased by euro 13 million. Changes included net payments for euro 374 million and, as increase, currency translation differences arose from the translation of financial statements denominated in currencies other than euro and translation differences arising on debt taken on by euro-reporting subsidiaries denominated in foreign currency which are translated into euros at year-end exchange rates of euro 172 million.

Debt from banks of euro 7,224 million related to committed borrowing facilities for euro 1,812 million.

Debt from other financial institutions of euro 472 million (euro 512 million at December 31, 2009) included euro 17 million of finance lease transactions (euro 24 million at December 31, 2009).

Eni entered into long-term borrowing facilities with the European Investment Bank which were subject to the maintenance of certain performance indicators based on Eni’s consolidated financial statements or the maintenance of a minimum level of credit rating. As of the balance sheet date, Eni was in compliance with those covenants. According to the agreements, should the Company fail to comply with maintenance of a minimum credit rating, new guarantees would be provided to be agreed upon with the European Investment Bank. At December 31, 2009 and 2010, the amount of short and long-term debt subject to restrictive covenants was euro 1,508 million and euro 1,685 million, respectively. A possible non-compliance with those covenants would be immaterial to the Company’s ability to finance its operations. Eni is in compliance with the covenants contained in its financing arrangements. During 2010, Saipem repaid financial debt which was subject to certain performance indicators (euro 75 million).

Bonds of euro 13,572 million consisted of bonds issued within the Euro Medium Term Notes Program for a total of euro 10,678 million and other bonds for a total of euro 2,894 million.

Fair value was calculated by discounting the expected future cash flows at rates ranging from 0.8% to 4.1% (1.0% and 4.5% at December 31, 2009).

At December 31, 2010 Eni did not pledge restricted deposits as collateral against its borrowings.

Information on net borrowings
In assessing its capital structure, Eni uses net borrowings, which is a non-GAAP financial measure. Eni calculates net borrowings as total finance debt (short-term and long-term debt) derived from its Consolidated Financial Statements prepared in accordance with IFRS as endorsed by IASB less: cash, cash equivalents and certain highly liquid investments not related to operations including, among others, non-operating financing receivables and securities not related to operations. Non-operating financing receivables consist mainly of deposits with banks and other financing institutions and deposits in escrow. Securities not related to operations consist primarily of government bonds and securities from financing institutions. These assets are generally intended to absorb temporary surpluses of cash as part of the Company’s ordinary management of financing activities.

Management believes that net borrowings is a useful measure of Eni’s financial condition as it provides insight about the soundness of Eni’s capital structure and the ways by which Eni’s operating assets are financed. In addition, management utilizes the ratio of net borrowings to total shareholders’ equity including non-controlling interest (leverage) to assess Eni’s capital structure, to analyze whether the ratio between finance debt and shareholders’ equity is well balanced according to industry standards and to track management’s short-term and medium-term targets. Management continuously monitors trends in net borrowings and trends in leverage in order to optimize the use of internally-generated funds versus funds from third parties. The measure calculated in accordance with IFRS that is most directly comparable to net borrowings is total debt (short-term and long-term debt). The most directly comparable measure, derived from IFRS reported amounts, to calculate leverage is the ratio of total debt to shareholders’ equity (including non-controlling interest). Eni’s presentation and calculation of net borrowings and leverage may not be comparable to that of other companies.

Provision for site restoration and abandonment and social projects amounted to euro 5,741 million of which euro 5,373 million related to the discounted estimation of future costs relating to decommissioning of oil and natural gas production facilities at the end of the producing lives of fields, well-plugging, abandonment and site restoration. The increase in the provision for the year amounted to euro 558 million and was primarily due to changes of estimated expenditures and the initial recognition in the estimates of future costs made by Nigerian Agip Oil Co Ltd (euro 125 million) and Eni Petroleum Co Inc (euro 117 million) and the recognition of social projects by Eni North Africa BV (euro 287 million). Also an amount of euro 238 million was recognized through profit and loss as accretion charge for the period. The discount rates adopted ranged from 2.1% to 8.9% (from 1.9% to 8.8% at December 31, 2009). Other increases of euro 318 million included currency translation differences (euro 190 million) and reclassification of the provision held by Società Adriatica Idrocarburi SpA (euro 137 million) from assets held for sale following the decision of the proposed buyer not to acquire the 100% stake. Management estimates that main expenditures associated with site restoration and abandonment operations will be incurred over a 25-year period starting from 2018.

Provision for environmental risks of euro 3,104 million primarily related to the estimated future costs of environmental cleaning-up and remediation in accordance with applicable laws and regulations. Also the provision included the estimated costs of environmental cleaning-up and restoring areas owned or held in concession by the Company, part of its industrial sites which were divested, shut-down or liquidated in previous reporting periods. Those environmental provisions are recognized when an environmental project is approved by or filed with the relevant administrative authorities or a constructive obligation has arisen whereby the Company commits itself to perform certain cleaning-up and restoration projects and reliable cost estimation is available. Based on this latter assumption, the Company recorded an environmental charge amounting to euro 1,109 million to account for its proposal for a global transaction with the Italian Ministry for the Environment, whereby the Company pledged to execute certain environmental projects relating nine sites of national interest (Priolo, Napoli Orientale, Brindisi, Pieve Vergonte, Cengio, Crotone, Mantova, Porto Torres and Gela). At those sites, the Group companies have started, as guiltless owners of a number of industrial areas, environmental restoration and clean up activities. The proposal also contemplates the settlement of a number of pending proceedings relating to clean up issues and environmental damage. More information about that issue is reported in "Item 5 – Operating and Financial Review and Prospects – Significant Transactions". At December 31, 2010 provisions for environmental risks were primarily related to Syndial SpA (euro 2,465 million) and to the Refining & Marketing segment (euro 455 million).

Provision for legal and other proceedings of euro 692 million primarily included charges expected on failure to perform certain contractual obligations and estimated future losses on pending litigation including legal, antitrust and administrative matters. These provisions are stated on the basis of Eni’s best estimate of the expected probable liability and primarily related to the Gas & Power segment (euro 238 million) and Syndial SpA (euro 225 million). Reversal of utilized provisions of euro 297 million included the payment related the settlement of the TSKJ matter with U.S. Authorities (euro 250 million). The matter is fully disclosed in Note 34 – Guarantees, commitments and risks – Legal Proceedings. Reversal of unutilized provisions of euro 310 million included the favorable outcome of

an antitrust proceeding of 2003 resulting in an amount significantly lower than the amount that was originally accrued on the base of a resolution by the Italian Antitrust Authority, who in a previous reporting period charged Eni with anti-competitive behavior for having allegedly refused third party access to a pipeline for importing natural gas from Algeria to Italy (euro 270 million).

Loss adjustments and actuarial provisions for Eni’s insurance companies of euro 398 million represented the liabilities towards third parties accrued for claims on insurance policies underwritten by Eni’s insurance company, Eni Insurance Ltd. In relation to such liability, Eni recorded in the assets of the balance sheet receivables for euro 98 million towards insurance companies for reinsurance contracts.

28 Provisions for employee benefits
Provisions for employee benefits were as follows:

(euro million) |  | Dec. 31, 2009 |  | Dec. 31, 2010

TFR |  | 445 |  | 423
Foreign pension plans |  | 204 |  | 295

Other benefits |  | 188 |  | 206
|  | 944 |  | 1,032

Provisions for indemnities upon termination of employment primarily related to the provisions accrued by Italian companies for employee termination indemnities ("TFR"), determined using actuarial techniques and regulated by Article 2120 of the Italian Civil Code.

The indemnity is paid upon retirement as a lump sum payment the amount of which corresponds to the total of the provisions accrued during the employees’ service period based on payroll costs as revalued until retirement. Following the changes in regime, starting from January 1, 2007 the amount already then accrued and future benefits will be put in pension funds or the treasury fund held by the Italian administration for post-retirement benefits (INPS). For companies with less than 50 employees, it will be possible to continue the scheme as in previous years. Therefore, the allocation of future TFR provisions to pension funds or the INPS treasury fund determines that these amounts will be classified as costs to provide benefits under a defined contribution plan. Past unpaid amounts accrued before January 1, 2007 for post-retirement indemnities under the Italian TFR regime continue to represent costs to provide benefits under a defined benefit plan and must be assessed based on actuarial assumptions.

Pension funds are defined benefit plans provided by foreign subsidiaries located mainly in Nigeria and in Germany. Benefits under these plans consisted of payments based on seniority and the salary paid in the last year of service, or alternatively, the average annual salary over a defined period prior to retirement.

Group companies provide healthcare benefits to retired managers. Liability to these plans (FISDE and other foreign healthcare plans) and the current cost are limited to the contributions made by the company.

Other benefits primarily consisted of a deferred cash incentive plans, the long-term incentive plan and Jubilee awards. The provisions for the deferred cash incentive plans are assessed based on the estimated remuneration related to the probability of the company reaching planned targets that will be paid to managers reaching individual performance goals. The long-term incentive plan replaces the previous stock option assignments and provides for an incentive to be paid after a period of three years in an amount connected with the variation of a performance indicator. 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.

The value of employee benefits, estimated by applying actuarial techniques, consisted of the following:

The main actuarial assumptions used in the evaluation of post-retirement benefit obligations at year-end and in the estimate of costs expected for 2011 were as follows:

(%) |  | TFR |  | Foreign pension plans |  | FISDE and other foreign medical plans |  | Other benefits

2009 |  |  |  |  |  |  |  |
Discount rate |  | 5.0 |  | 2.7-11.0 |  | 5.0 |  | 2.0-5.0

Rate of price inflation |  | 2.0 |  | 0.9-10.0 |  | 2.0 |  | 2.0
2010 |  |  |  |  |  |  |  |
Discount rate |  | 4.8 |  | 2.7-14.0 |  | 4.8 |  | 1.8-4.8
Expected return rate on plan assets |  |  |  | 3.5-14.0 |  |  |  |

Rate of price inflation |  | 2.0 |  | 0.8-13.0 |  | 2.0 |  | 2.0

With regards to Italian plans, demographic tables prepared by Ragioneria Generale dello Stato (RG48) were used. Expected return rate by plan assets has been determined by reference to quoted prices expressed in regulated markets.

Plan assets consisted of the following:

(%) |  | Plan assets |  | Expected return

Securities |  | 13.0 |  | 6.4-7.4
Bonds |  | 36.4 |  | 1.8-14.0
Real estate |  | 2.0 |  | 6.4
Other |  | 48.6 |  | 0.5-14.0
Total |  | 100.0 |  |

The effective return of the plan assets amounted to euro 24 million (nil at December 31, 2009).

With reference to healthcare plans, the effects deriving from a 1% change of the actuarial assumptions of medical costs were as follows:

(euro million) |  | 1% Increase |  | 1% Decrease

Impact on the current costs and interest costs |  | 1 |  | (1 | )
Impact on net benefit obligation |  | 14 |  | (12 | )

The amount expected to be accrued to defined benefit plans for 2011 amounted to euro 125 million.

The analysis of changes in the actuarial valuation of the net liability with respect to prior year deriving from the non-correspondence of actuarial assumptions with actual values recorded at year-end was as follows:

(euro million) |  | TFR |  | Foreign pension plans |  | FISDE and other foreign medical plans |  | Other benefits

2009 |  |  |  |  |  |  |  |  |  |
Impact on net benefit obligation |  | (7 | ) |  | 4 |  |  | 3 |  | 2

Italian taxation law allows the carry-forward of tax losses over the five subsequent years. Losses suffered in the first three years of the company’s life can, however, be, for the most part, carried forward indefinitely. Foreign taxation laws generally allow the carry-forward of tax losses over a period longer than the five subsequent years, and in many cases, indefinitely. The tax rate applied to determine the portion of carry-forwards tax losses to be utilized equaled to: (i) an average rate of 34.0%, for Italian companies that are not included in the tax consolidation; (ii) a rate of 6.5%, equal to the additional IRES provided for energy companies that are included in the tax consolidation; and (iii) an average rate of 30.9%, for foreign companies.

Carry-forward tax losses of euro 1,298 million can be used in the following periods:

(euro million) |  | Italian subsidiaries |  | Foreign subsidiaries

|  | 152 |  | 1,146

Carry-forward tax losses for which is probable the offsetting against future taxable profit amounted to euro 837 million and were in respect of Italian subsidiaries for euro 152 million and of foreign subsidiaries for euro 685 million. Deferred tax assets recognized on these losses amounted to euro 26 million and euro 212 million, respectively.

Fair value of non-hedging derivatives of euro 344 million (euro 372 million at December 31, 2009) essentially referred to derivative contracts that do not meet the formal criteria to be designated as hedges under IFRS because they were entered into in order to manage the net business exposures in foreign currency exchange rates, interest rates and commodity prices. Therefore, such derivatives were not related to specific trade or financing transactions.

Fair value of cash flow hedge derivatives amounted to euro 157 million (euro 436 million at December 31, 2009) pertained to the Gas & Power segment (euro 275 million at December 31, 2009) and were designated to hedge surpluses or deficits of gas to achieve a proper balance in gas portfolio. Fair value of contracts expiring beyond 2011 is given in Note 20 – Other non-current receivables; fair value of contracts expiring by 2011 is given in Note 25 – Other current liabilities and in Note 13 – Other current assets. The effects of the evaluation at the fair value of cash flow hedge derivatives are given in Note 32 – Shareholders’ equity and in Note 36 – Operating expenses.

The nominal value of these derivatives referred to purchase and sale commitments for euro 383 million and euro 612 million, respectively (euro 1,544 million and euro 129 million at December 31, 2009).

Information on the hedged risks and the hedging policies is shown in Note 34 – Guarantees, commitments and risks – Risk factors.

The group’s liability for current income taxes of euro 40 million (euro 52 million at December 31, 2009) was due as special tax (with a rate lower than the statutory tax rate), relating to the option to increase the deductible tax bases of certain tangible and other assets to their carrying amounts as permitted by the 2008 Budget Law.

Other liabilities of euro 1,586 million (euro 1,566 million at December 31, 2009) included advances received by Suez following the long-term supplying of natural gas and electricity of euro 1,353 million (euro 1,455 million at December 31, 2009).

31 Assets held for sale and liabilities directly associated with assets held for sale
In 2010, non-current assets held for sale and liabilities directly associated with non-current assets held for sale of euro 517 million and euro 38 million pertained to the Gas & Power segment and related to: (i) Gas Brasiliano Distribuidora SA, a company that markets and distributes gas in an area of the São Paulo state, Brazil, for which Eni signed a preliminary agreement with an affiliate of Petrobras. The completion of the transaction is subject to approval of the relevant Brazilian authorities; (ii) Eni’s interests in gas transport pipelines from North Europe and Russia – Trans Europa Naturgas Pipeline Gesellschaft mbH & Co KG, Trans Europa Naturgas Pipeline Verwaltungs GmbH, Transitgas AG and Trans Austria Gasleitung GmbH – as well as assets and liabilities essentially related to marketing activities of gas transportation capacity of the consolidated companies Eni Gas Transport Deutschland SpA and Eni Gas Transport International SA. The divestment is part of the commitments presented by Eni to the European Commission to settle an antitrust proceeding related to alleged anti-competitive behavior in the natural gas

market ascribed to Eni without the ascertainment of any illicit behavior and consequently without imposition of any fines or sanctions. The Commission accepted Eni’s commitments as of September 29, 2010. The completion of the transactions is expected in the first half of 2011.

In 2009, non-current assets held for sale and liabilities directly associated with non-current assets held for sale amounted to euro 542 million and euro 276 million, respectively, which mainly relate to the divestment of certain mineral properties in Italy which were contributed in kind to two new entities Società Padana Energia SpA and Società Adriatica Idrocarburi SpA, for the disposal of Gas Brasiliano Distribuidora SA, a company operating in the distribution and marketing of natural gas in an area of São Paulo state in Brazil, and Distri RE SA, a company acquired following the acquisition of Distrigas NV.

Società Padana Energia SpA and Distri RE SA have been sold during 2010. Società Adriatica Idrocarburi SpA has been reclassified from assets held for sale following the decision of the proposed buyer not to acquire its 100% stake.

Risk factors

FOREWORD
The main risks that the Company is facing and actively monitoring and managing are the following: (i) the market risk deriving from exposure to fluctuations in interest rates, foreign currency exchange rates and commodity prices; (ii) the credit risk deriving from the possible default of a counterparty; and (iii) the liquidity risk deriving from the risk that suitable sources of funding for the Group’s operations may not be available.

Financial risks are managed in respect of guidelines defined by the parent company, targeting to align and coordinate Group companies’ policies on financial risks ("Eni Guidelines on Management and Control of Financial Risks").

In 2010, driven by a deep change in its relative market risk profile determined by structural changes in the market, Eni’s Gas & Power Division adopted new pricing and risk management strategies for actively managing economic margins, that have been approved by the Board of Directors on June 15, 2010. As a result of the implementation of these new activities, reviews of the principles included in the Guidelines are expected in 2011.

Market risk
Market risk is the possibility that changes in currency exchange rates, interest rates or commodity prices will adversely affect the value of the Group’s financial assets, liabilities or expected future cash flows. The Company actively manages market risk in accordance with a set of policies and guidelines that provide a centralized model of handling finance, treasury and risk management operations based on the Company’s departments of operational finance: the parent company’s (Eni SpA) finance department, Eni Coordination Center, Eni Finance USA and Banque Eni which is subject to certain bank regulatory restrictions preventing the Group’s exposure to concentrations of credit risk and Eni Trading & Shipping which executes certain activities relating to commodity derivatives. In particular, Eni SpA and Eni Coordination Center manage subsidiaries’ financing requirements in and outside Italy, respectively, covering funding requirements and using available surpluses. All transactions concerning currencies and derivative financial contracts are managed by the parent company as well as the activity of negotiating emission trading certificates. The commodity risk is managed by each business unit with Eni Trading & Shipping executing the negotiation of hedging derivatives. Eni uses derivative financial instruments (derivatives) in order to minimize exposure to market risks related to changes in exchange rates and interest rates and to manage exposure to commodity prices fluctuations. Eni does not enter into derivative transactions on interest rates or exchange rates on a speculative basis.

F-70

##### Table of Contents

Commodity derivatives are entered into with the aim of:

a) |  | hedging of certain underlying commodity prices set in a contractual arrangement with a third party. Hedging derivatives can be entered also to hedge highly probable future transactions;
b) |  | effectively managing the economic margin (positioning). This consists of entering purchase/sale commodity contracts in both commodity and financial markets aiming at altering the risk profile associated with a portfolio of physical assets of each business unit in order to improve margins associated to those assets in case of favorable trends in the commodity pricing environment;
c) |  | arbitrage. It consists of entering purchase/sale commodity contracts in both commodity and financial markets, targeting the possibility of earning a profit (or reducing the logistical costs associated to owned assets) leveraging any price differences in the marketplace;
d) |  | proprietary trading. It consists in entering purchase/sale commodity contracts in both commodity and financial markets, targeting of earning an uncertain profit, should certain expectations fulfill about favorable trends in the commodity pricing environment.

In addition, commodity derivatives may also be included in origination activities. This activity takes place in wholesale markets and provides for structuring contracts by an originator in order to meet the specific requirements of an internal or external counterparty. According to the management strategy adopted, origination services can be asset based, when the originator replicates the contract contents with profiles and capacities of its own assets in the logic of natural hedging, or not asset based, when price and volume risk profiles can be managed under a trading/positioning logic or a hedging logic that is implemented on each leg of the contract.

The framework defined by Eni’s policies and guidelines prescribes that measurement and control of market risk be performed on the basis of maximum tolerable levels of risk exposure defined in terms of limits of stop loss, which expresses the maximum tolerable amount of losses associated with a certain portfolio of assets over a pre-defined time horizon, or in accordance with Value-at-Risk (VaR) techniques. Those techniques make a statistical assessment of the market risk associated with the Group’s activity, i.e., potential gain or loss in fair values, due to changes in market conditions taking account of the correlation existing among changes in fair value of existing instruments.

Eni’s finance departments define maximum tolerable levels of risk exposure to changes in interest rates and foreign currency exchange rates in terms of Value at Risk, pooling Group companies risk positions. Eni’s calculation and measurement techniques for interest rate and foreign currency exchange rate risks are in accordance with established banking standards, as established by the Basel Committee for bank activities surveillance. Tolerable levels of risk are based on a conservative approach, considering the industrial nature of the Company. Eni’s guidelines prescribe that Eni’s Group companies minimize these kinds of market risks by transferring risk exposure to the parent company’s finance department.

With regard to the commodity risk, Eni’s policies and guidelines define rules to manage this risk with the objective of optimization of core activities and the pursuing of preset targets of stabilizing industrial and commercial margins. The maximum tolerable level of risk exposure is defined in terms of Value at Risk and stop loss in connection with exposure deriving from commercial activities as well as exposure deriving from proprietary trading executed by the subsidiary Eni Trading & Shipping. Internal mandates to manage the commodity risk provide for a mechanism of allocation of the Group maximum tolerable risk level to each business units. In this framework, Eni Trading & Shipping, in addition to managing risk exposure associated with its own commercial activity and proprietary trading, pools Group companies requests for negotiating commodity derivatives, ensuring execution services to Group companies, while the strategic risk exposure to commodity prices fluctuations – i.e. the impact on the Group’s business results deriving from changes in commodity prices – is monitored in terms of Value at Risk , albeit not hedged in a systematic way. Accordingly, Eni evaluates the opportunity to mitigate its commodity risk exposure by entering into hedging transactions in view of certain acquisition deals of oil and gas reserves as part of the Group’s strategy to achieve its growth targets or ordinary asset portfolio management. The Group controls commodity risk with a maximum Value at Risk and stop loss limit awarded to each business unit. Hedging needs from business units are pooled by Eni Trading & Shipping which also manages its own risk exposure.

The strategic risk is the economic risk which is intrinsic to each business unit. This exposure to strategic risk is not managed through specific systematic activities due to a strategic decision made by the Company, except for extraordinary business or market conditions. Therefore, internal risk policies and guideline do not foresee any mandate to manage, or any maximum tolerable level of risk exposure. To date, exposure to the strategic risk is associated with plans for commercial development of proved and unproved oil and gas reserves, long-term gas supply contracts for the portion not balanced by in-place or highly probable sale contracts, refining margins and minimum compulsory stock. Any hedging activity of the strategic risk is the sole responsibility of Eni’s top management, due to the extraordinary conditions that may lead to such decision. This kind of transaction is not subject to specific risk limits for its nature, but is however subject to monitoring and assessment activities.

##### Table of Contents

The three different market risks, for which management and control have been summarized above, are described below.

Exchange rate risk
Exchange rate risk derives from the fact that Eni’s operations are conducted in currencies other than the euro (mainly in the U.S. dollar). Revenues and expenses denominated in foreign currencies may be significantly affected by exchange rates fluctuations due to conversion differences on single transactions arising from the time lag existing between execution and definition of relevant contractual terms (economic risk) and conversion of foreign currency-denominated trade and financing payables and receivables (transactional risk). Exchange rate fluctuations affect the Group’s reported results and net equity as financial statements of subsidiaries denominated in currencies other than the euro are translated from their functional currency into euro. Generally, an appreciation of the U.S. dollar versus the euro has a positive impact on Eni’s results of operations, and viceversa. Eni’s foreign exchange risk management policy is to minimize economic and transactional exposures arising from foreign currency movements. Eni does not undertake any hedging activity for risks deriving from the translation of foreign currency denominated profits or assets and liabilities of subsidiaries which prepare financial statements in a currency other than the euro, except for single transactions to be evaluated on a case-by-case basis. Effective management of exchange rate risk is performed within Eni’s central finance departments which match opposite positions within Group companies, hedging the Group net exposure through the use of certain derivatives, such as currency swaps, forwards and options. Such derivatives are evaluated at fair value on the basis of market prices provided by specialized sources. Changes in fair value of those derivatives are normally recognized through the profit and loss account as they do not meet the formal criteria to be recognized as hedges in accordance with IAS 39. The Value-at-Risk techniques are based on variance/covariance simulation models and are used to monitor the risk exposure arising from possible future changes in market values over a 24-hour period within a 99% confidence level and a 20-day holding period.

Interest rate risk
Changes in interest rates affect the market value of financial assets and liabilities of the company and the level of finance charges. Eni’s interest rate risk management policy is to minimize risk with the aim to achieve financial structure objectives defined and approved in the management’s finance plans. Borrowing requirements of the Group’s companies are pooled by the Group’s central finance department in order to manage net positions and the funding of portfolio developments consistently with management’s plans while maintaining a level of risk exposure within prescribed limits. Eni enters into interest rate derivative transactions, in particular interest rate swaps, to effectively manage the balance between fixed and floating rate debt. Such derivatives are evaluated at fair value on the basis of market prices provided from specialized sources. Changes in fair value of those derivatives are normally recognized through the profit and loss account as they do not meet the formal criteria to be accounted for under the hedge accounting method in accordance with IAS 39. Value at risk deriving from interest rate exposure is measured daily on the basis of a variance/covariance model, within 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 and gas prices generally has a negative impact on Eni’s results of operations and viceversa. Eni manages exposure to commodity price risk arising in normal trading and commercial activities in view of achieving stable margins. In order to accomplish this, Eni uses derivatives traded on the organized markets of ICE and NYMEX (futures) and derivatives traded over the counter (swaps, forward, contracts for differences and options) with the underlying commodities being crude oil, natural gas, refined products or electricity. Such derivatives are evaluated 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. Changes in fair value of those derivatives are normally recognized through the profit and loss account as they do not meet the formal criteria to be recognized as hedges in accordance with IAS 39. Value at risk deriving from commodity exposure is measured daily on the basis of a historical simulation technique, within a 95% confidence level and a one-day holding period.

The following table shows amounts in terms of Value at Risk , recorded in 2010 (compared with 2009) relating to interest rate and exchange rate risks in the first section, and commodity risk in the second section. Value-at-Risk values are stated in U.S. dollars, the currency most widely used in oil products markets. The relevant increase reported by the Gas & Power Division derives from the circumstance that in the second half of 2010, Value at Risk has been calculated according to new assumptions on non contracted exposures (based on benchmark indices related to prices in European hubs) consistently with the new pricing and risk management model of the Gas & Power Division approved by Eni’s Board of Directors.

Credit risk
Credit risk is the potential exposure of the Group to losses in case counterparties fail to perform or pay amounts due. The Group manages differently credit risk depending on whether credit risk arises from exposure to financial counterparties or to customers relating to outstanding receivables. Individual business units and Eni’s corporate financial units and Eni Adfin are responsible for managing credit risk arising in the normal course of the business. The Group has established formal credit systems and processes to ensure that before trading with a new counterpart can start, its creditworthiness is assessed. Also credit litigation and receivable collection activities are assessed. Eni’s corporate units define directions and methods for quantifying and controlling customer’s reliability. With regard to risk arising from financial counterparties, Eni has established guidelines prior to entering into cash management and derivative contracts to assess the counterparty’s financial soundness and rating in view of optimizing the risk profile of financial activities while pursuing operational targets. Maximum limits of risk exposure are set in terms of maximum amounts of credit exposures for categories of counterparties as defined by the Company’s Board of Directors taking into accounts the credit ratings provided by primary credit rating agencies on the marketplace. Credit risk arising from financial counterparties is managed by the Group central finance departments, including Eni’s subsidiary Eni Trading & Shipping which specifically engages in commodity derivatives transactions and by Group companies and Division, only in the case of physical transactions with financial counterparties consistently with the Group centralized finance model. Eligible financial counterparties are closely monitored to check exposures against limits assigned to each counterparty on a daily basis. Exceptional market conditions have forced the Group to adopt contingency plans and under certain circumstances to suspend eligibility to be a Group financial counterparty. Actions implemented also have been intended to limit concentrations of credit risk by maximizing counterparty diversification and turnover. Counterparties have also been selected on more stringent criteria particularly in transactions on derivatives instruments and with maturity longer than a three-month period. As of December 31, 2010, Eni had no significant concentration of credit risk.

Liquidity risk
Liquidity risk is the risk that suitable sources of funding for the Group may not be available, or the Group is unable to sell its assets on the marketplace as to be unable to meet short-term finance requirements and to settle obligations. Such a situation would negatively impact Group results as it would result in the Company incurring higher borrowing expenses to meet its obligations or under the worst of conditions the inability of the Company to continue as a going concern. As part of its financial planning process, Eni manages the liquidity risk by targeting such a capital structure as to allow the Company to maintain a level of liquidity adequate to the Group’s needs optimizing the opportunity cost of maintaining liquidity reserves also achieving an efficient balance in terms of maturity and composition of finance debt. The Group capital structure is set according to the Company’s industrial targets and within the limits established by the Company’s Board of Directors who are responsible for prescribing the maximum ratio of debt to total equity and minimum ratio of medium and long-term debt to total debt as well as fixed rate medium and long-term debt to total medium and long-term debt. In spite of ongoing tough credit market conditions resulting in higher spreads to borrowers, the Company has succeeded in maintaining access to a wide range of funding at competitive rates through the capital markets and banks. The actions implemented as part of Eni’s financial planning have enabled the Group to maintain access to the credit market particularly via the issue of commercial paper which is also targeted to increase the flexibility of funding facilities. In particular in 2010, Eni

issued bonds addressed to institutional investors on the euro market (two emissions for euro 1 billion each) and to professional investors on the dollar market for $800 million. The above mentioned actions were aimed at ensuring availability of suitable sources of funding to fulfill short-term commitments and due obligations while also preserving the necessary financial flexibility to support the Group’s development plans. In doing so, the Group has pursued an efficient balance of finance debt in terms of maturity and composition leveraging on the structure of its lines of credit, particularly the committed ones. 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.

At December 31, 2010, Eni maintained short-term committed and uncommitted unused borrowing facilities of euro 10,358 million, of which euro 2,498 million were committed, and long-term committed unused borrowing facilities of euro 4,901 million. These facilities were under interest rates that reflected market conditions. Fees charged for unused facilities were not significant. Eni has in place a program for the issuance of Euro Medium Term Notes up to euro 15 billion, of which about euro 10.4 million were drawn as of December 31, 2010.

The Group has debt ratings of A+ and A-1 respectively for long (outlook stable) and short-term debt assigned by Standard & Poor’s and Aa3 and P-1 (outlook stable) assigned by Moody’s.

Expected payments by period under contractual obligations and commercial commitments
In addition to finance debt and trade payables presented in the financial statements, the Group has in place a number of contractual obligations arising in the normal course of the business. To meet these commitments, the Group will have to make payments to third parties. The Company’s main obligations are take-or-pay clauses in contracts of the Gas & Power segment, whereby the Company obligations consist of off-taking minimum quantities of product or service or paying the corresponding cash amount that entitles the Company to off-take the product in future years. Future obligations in connection with these contracts were calculated by applying the forecasted prices of energy or services included in the four-year business plan approved by the Company’s Board of Directors.

The table below summarizes the Group principal contractual obligations as of the balance sheet date, shown on an undiscounted basis.

Fair value of financial instruments
Following the classification of financial assets and liabilities, measured at fair value in the balance sheet, is provided according to the fair value hierarchy defined on the basis of the relevance of the inputs used in the measurement process. In particular, on the basis of the features of the inputs used in making the measurements, the fair value hierarchy shall have the following levels:

F-76

##### Table of Contents

a) |  | Level 1: quoted prices (unadjusted) in active markets for identical financial assets or liabilities;
b) |  | Level 2: measurements based on the basis of inputs, other than quoted prices above, which, for assets and liabilities that have to be measured, can be observable directly (e.g. prices) or indirectly (e.g. deriving from prices); and
c) |  | Level 3: inputs not based on observable market data.

Financial instruments measured at fair value in the balance sheet as of at December 31, 2010 were classified as follows: (i) level 1, "Other financial assets held for trading or available for sale" and "Non-hedging derivatives - Future"; and (ii) level 2, derivative instruments different from "Future" included in "Other current assets", "Other non-current assets", "Other current liabilities" and "Other non-current liabilities". During 2010 no transfers were done between the different hierarchy levels of fair value.

Legal Proceedings
Eni is a party to a number of civil actions and administrative arbitral and other judicial proceedings arising in the ordinary course of business. Based on information available to date, and taking into account the existing risk provisions, 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 cannot be estimated reliably.

1. Environment

1.1 Criminal proceedings

ENI SPA
(i) Subsidence. The Court of Rovigo conducted investigations concerning a subsidence phenomenon allegedly caused by hydrocarbon exploration and extraction activities in the Ravenna and North Adriatic area both on land and in the sea. Eni appointed 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 magnitude and effects and any actions appropriate to reduce or to neutralize any subsidence phenomenon in the area. This commission produced a study which excludes the possibility of any risk to human health or damage to the environment. The study also states that worldwide there are no instances of accidents of harm to public safety caused by subsidence induced by hydrocarbon production. It also shows that Eni employs the most advanced techniques for monitoring, measuring and controlling the soil. This proceeding is in the first level hearing stage. The Veneto Region, other local bodies and two private entities have been acting as plaintiffs. Eni was admitted as a defendant. At the end of the renewed preliminary investigations the Court of Ravenna requested the

closing of the proceeding. A number of plaintiffs have been appealed against this decision. The hearing for the review of the appeal against the dismissal request was held on November 11, 2010. Basing on this hearing, the Judge for the Preliminary Hearings retained the decision. On February 14, 2011 the Judge for the Preliminary Hearings decided to accept the request of dismissal of the proceeding for all the defendants issued by the Public Prosecutor. The Judge also decided in favor of releasing the hydrocarbon fields and their restitution to the entitled entities.

(ii) Alleged damage – Prosecuting body: Public Prosecutor of Gela. In 2002, the Public Prosecutor of Gela commenced a criminal investigation to ascertain alleged damage caused by emissions of the Gela plant, owned by Polimeri Europa SpA, Syndial SpA (formerly EniChem SpA) and Raffineria di Gela SpA. The Judge for the Preliminary Hearings dismissed the accusation of adulteration of food products, while the proceeding for the other allegations regarding pollution and environmental damage remains underway. The trial ended in acquittal with regard to the general manager and officer pro tempore of the refinery. The sentence of the Gela Tribunal stated that the charges were lacking factual basis. A number of farmers of Gela area, who have been acting as plaintiffs in the first level hearing stage, filed an appeal against the acquittal sentence in the civil action. In the first hearing on December 17, 2009, the Public Prosecutor asked for the dismissal of the appeal confirming the motivations of the acquittal sentence in the first degree proceeding. The Court of Rome postponed the proceeding to the hearing of February 25, 2010. In February 25, 2010 the Court confirmed the acquittal sentence with a ruling filed on April 29, 2010.

(iii) Alleged 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 alleged negligent fire, environmental crimes and crimes against natural beauty. First degree proceedings ended with an acquittal sentence. In November 2007, the Public Prosecutors of Gela and of Caltanissetta filed an appeal against this decision. In the first hearing the Court re-opened the examining phase, arranging a collegial appraiser. On December 10, 2009 the appraisers appointed by the Court filed their report. On January 21, 2010, the Court of Caltanissetta announced an acquittal sentence for all the defendants.

(iv) Investigation of the quality of groundwater in the area of the refinery of Gela. In 2002, the Public Prosecutor of Gela commenced a criminal investigation concerning the refinery of Gela to ascertain the quality of groundwater in the area of the refinery. Eni is charged with having breached environmental rules concerning the pollution of water and soil and of illegal disposal of liquid and solid waste materials. The preliminary hearing phase was closed for one employee who would stand trial, while the preliminary hearing phase is ongoing for other defendants. During the hearings the Judge admitted as plaintiffs three environmental associations. The proceeding was subsequently assigned to a different Judge and was disposed at the renewal of the debate phase. During the debate phases, indictment and defense witnesses were examined. Subsequently, the first technical appraiser of the defense was examined. On May 14, 2010, following the examination, the Court of Gela issued a sentence whereby on one side criminal accusation against the above mentioned employee was dismissed as a result of the statute of limitations, on the other side the defendant was condemned to the payment of legal costs and compensation to the plaintiffs. The amount of the compensation will be determined by a resolution of a Civil Court. The sentence was filed on June 3, 2010. The Company has filed an appeal with the Second Degree Court of Caltanissetta. In the first hearing the proceeding was postponed due to a lack of notification.

(v) Alleged negligent fire (Priolo). The Public Prosecutor of Siracusa commenced an investigation regarding certain Eni managers who were previously in charge of conducting operations at the Priolo refinery (Eni divested this asset in 2002) 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. After preliminary investigations the Public Prosecutor requested the opening of a proceeding against the mentioned managers for negligent behavior. The first hearing, in which the parties could present themselves as plaintiffs, was scheduled for February 26, 2010. On February 5, 2010, the Court of Siracusa, following the exception of inadmissibility issued by the defendants, admitted as sole plaintiff the Ministry for the Environment, excluding all the other counterparts, including the Council of Ministers. The proceeding continues with the examination of three witnesses of the Public Prosecutor. In the hearing on February 26, 2010, the Judge accepted all the evidences filed by the counterparts. In the hearing of April 14, 2010 the Public Prosecutor commenced the review of the texts that continued in a number of subsequent hearings.

(vi) Groundwater at the Priolo site – Prosecuting body: Public Prosecutor of Siracusa. The Public Prosecutor of Siracusa (Sicily) has started an investigation in order to ascertain the level of contamination of the groundwater at the Priolo site. The Company has been notified that a number of its executive officers are being investigated who were in charge at the time of the events subject to probe, including chief executive officers and plant general managers of the Company’s subsidiaries AgipPetroli SpA (now merged into the parent company Eni SpA in the Refining & Marketing division), Syndial and Polimeri Europa. Probes on technical issues required by the Prosecutor were finalized on October 15, 2009. On February 25, 2010, the technical survey was filed. According to the survey, the ground and the groundwater at the Priolo site should be considered polluted according to Law Decree No. 152/2006. This contamination was caused by a spill-over made in the period prior to 2001 and not subsequent to

2005; the equipment still operating on the site represents another source of risk, in particular those owned by ISAB Srl (ERG). According to the findings of this report the defense of Syndial, Polimeri Europa and Eni SpA (Refining & Marketing division) will file a defensive memorandum to request the dismissal of the proceeding. The Public Prosecutor requested the dismissal of the proceeding. The decision of the Judge on the dismissal on the proceeding is still pending.

(vii) Fatal accident Truck Center Molfetta – Prosecuting body: Public Prosecutor of Trani. On March 3, 2008 in the Municipality of Molfetta a fatal accident occurred that caused the death of four workers assigned to the cleaning of a tank car owned by the company FS Logistica, part of the Italian Railways Group. The tank was used for the transportation of liquid sulfur produced by Eni in the Refinery of Taranto and destined to the client company Nuova Solmine. Consequently a criminal action commenced against certain employees of FS Logistica and of its broker "La Cinque Biotrans" and, under the provisions of Legislative Decree No. 231/2001, against the two above mentioned companies and the company responsible for the clean up of the tank car - Truck Center. On October 26, 2009 the First Degree Court concluded that both the above mentioned persons and the three companies were guilty. Additionally, the documentation related to the trial was forwarded to the Public Prosecutor of Trani in order to ascertain the eventual responsibilities of Eni and Nuova Solmine employees in relation to the fatal accident and also to the Public Prosecutors of Taranto and Grosseto (competent for Nuova Solmine) in order to ascertain eventual irregularities in the procedures of handling and transporting liquid sulfur. Following the sentence, the Public Prosecutor of Trani commenced an investigation against a number of employees of Nuova Solmine and an employee of Eni’s Refining & Marketing division, responsible for marketing liquefied sulfur. On April 14, 2010, the Judge for the Preliminary Hearings notified the Eni’s employee a request of extension of the preliminary investigations. On May 11, 2010, Eni SpA, eight employees of the company and a former employee were notified of the closing of the investigation into manslaughter, grievous bodily harm and illegal disposal of waste materials. A number of defendants filed defensive memoranda. The Public Prosecutor has removed three defendants and transmitted evidence to the Judge for the Preliminary investigations requesting to dismiss the proceeding. The Judge for the Preliminary Investigation accepted the above mentioned request. The Judge postponed the preliminary hearing for the positions not dismissed to February 23, 2011. In this hearing, the Judge scheduled the hearing for the eventual admittance as plaintiffs of the Puglia Region, the Municipality of Molfetta and a relative of one of the victims for April 19, 2011. On that occasion, the counterparts shall state the kind of procedure that they intend to adopt.

(viii) Seizure of areas located in the Municipalities of Cassano allo Jonio and Cerchiara di Calabria – Prosecuting body: Public Prosecutor of Castrovillari. On June 11, 2010 the Company received a notification of a judicial measure for the preventive seizure of areas located in the Municipalities of Cassano allo Jonio and Cerchiara di Calabria, following a prior seizure of other areas in the same municipalities notified through a judicial measure in February 2010. The above mentioned decisions were the result of an investigation commenced after the damage of the HDPE covering the zinc ferrites generated in the industrial site of Pertusola Sud and, based on the Court’s conclusions, illegally stored in the Municipalities of Cassano allo Jonio and Cerchiara di Calabria. The impounded areas are those where the above mentioned waste was stored. The proceeding is in the phase of the preliminary hearings. The circumstances object of investigation are the same considered in the criminal action concluded in 2008 with an acquittal sentence for one of the defendants while the Judge dismissed the accusation for all the other defendants as a result of the statute of limitations. In this case the accusation is of omitted clean up. Syndial SpA gave the availability for the removal of the waste materials, the related operations are still pending.

SYNDIAL SPA
(ix) Porto Torres – Prosecuting body: Public Prosecutor of Sassari. In March 2009, the Public Prosecutor of Sassari (Sardinia) resolved to commence a criminal trial against a number of executive officers and managing directors of companies engaging in petrochemicals operations at the site of Porto Torres, including the manager responsible for plant operations of the Company’s fully-owned subsidiary Syndial. The charge involves environmental damage and poisoning of water and crops. In the preliminary hearing on July 17, 2009, the Province of Sassari, the Association Anpana (animal preservation) and the company Fratelli Polese Snc situated in the industrial site have been acting as plaintiffs. None of these parties claimed the identification of the civil responsible and the damage quantification that will be asked in a second step. The legal defense of Syndial requested further time for the recognition of the proceeding plaintiffs and the verification of their right to institute proceedings. The defense of Syndial filed a number of exceptions on the admissibility in acting as plaintiffs of the counterpart; the Judge addressed the question in a hearing in February 2010. In this hearing the Judge, based on the exceptions issued by Syndial on the lack of connection between the action as plaintiff and the charge, excluded all the counterparts that have been acting as plaintiff with regard to the serious pathologies related to the existence of poisoning agents in the marine fauna of the industrial port of Porto Torres; the Judge admitted as plaintiffs the Municipality of Sassari, the Environmental Association Anpana and the company Fratelli Polese Snc. The Judge also requested that Syndial SpA, Polimeri Europa SpA, Ineos Vinyls and Sasol Italy SpA stand trial. The proceeding continues for the constitution as defendants of the said part. In the hearing of October 18, 2010, then postponed to

F-79

##### Table of Contents

November 6, 2010, the legal defense filed the exception of lack of territorial competence of the Judges of the Court of Sassari as part potentially injured by the alleged crime. In the hearing of January 31, 2011, the Judge for the Preliminary Hearings rejected the above mentioned exceptions. Syndial defense submitted further preliminary issues related to the invalidity of the notice of conclusion of preliminary investigation. In a subsequent hearing, the Judge rejected all the exceptions on the invalidity of the notice of conclusion of preliminary investigation. In the following hearing held on February 15, 2011, Syndial issued a further exception on the inadmissibility of the use of investigation acts filed by the Public Minister after the deadline.

1.2 Civil and administrative proceeding

SYNDIAL SPA (FORMER ENICHEM SPA)
(i) Alleged pollution caused by the activity of the Mantova plant. In 1992, the Ministry for the Environment summoned EniChem SpA (now Syndial SpA) and Edison 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. Edison agreed on a settlement with the Ministry whereby Edison quantified compensation for environmental damage freeing from any obligation Syndial, which purchased the plant in 1989. Negotiations between the parts for the quantification of the environmental damage (relating only to 1990) are underway; the judgment has been postponed a number of times until the next hearing that has been scheduled for October 13, 2011. The Board of State Lawyers is confident on the positive closing of the transaction before this date, depending on the time necessary to the Ministry for completing its evaluation.

(ii) Summon before the Court of Venice for environmental damages allegedly caused to the lagoon of Venice by the Porto Marghera plants. On December 2002, EniChem SpA (now Syndial SpA), jointly with Ambiente SpA (now merged into Syndial SpA) and European Vinyls Corporation Italia SpA (EVC Italia, then Ineos Vinyls SpA, actually Vinyls Italia SpA) was summoned before the Court of Venice by the Province of Venice. The province requested compensation for environmental damages that initially were not quantified, allegedly 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. EVC Italia and the actual company, Vinyls Italia, presented an action to be indemnified by Eni’s Group companies in case the alleged pollution is proved. The Province of Venice, in the preliminary stage of the proceeding, filed claims amounting to euro 287 million. Syndial submitted its written reply evidencing that the above mentioned damage quantification has been made lacking of probations for the damage and based on evidence that allowed the Court of First and Second Instance to disclaim EniChem of any responsibility through definitive sentence. In the hearing on October 16, 2009, scheduled to review the technical appraisal, the Court declared the interruption of the proceeding because Vinyls Italia had undergone a reorganization procedure. The proceeding has been suspended until April 22, 2010 when the Province of Venice pursuant to Article 303 of the Italian Penal Code restarted the proceeding. The subsequent hearing for the resume of the proceeding took place on September 24, 2010. In that hearing the Judge decided to reschedule the hearing that will review the position of Vinyls Italia and the consultants appraisals filed by the parties. As the Judge resolved not to hear the consultants again, the hearing has been postponed to September 2011 to review the findings.

(iii) Claim of environmental damages, allegedly caused by industrial activities in the area of Crotone – Prosecuting bodies: the Council of Ministers, the Ministry for the Environment, the Delegated Commissioner for Environmental Emergency in the Calabria Region and the Calabria Region. The Council of Ministers, the Ministry for the Environment, the Delegated Commissioner for Environmental Emergency in the Calabria Region and the Calabria Region requested Syndial to appear before the Court of Milan to face charges of causing environmental damage caused by the operations of Pertusola Sud SpA (merged in EniChem, now Syndial) in the Crotone site. This first degree proceeding was generated in January 2008 by the unification of two different actions, the first brought by Calabria Region in October 2004, the second one by the Council of Ministers, the Ministry for the Environment and the Delegated Commissioner for Environmental Emergency in the Calabria Region commenced in February 2006. The Calabria Region is claiming compensation amounting to euro 129 million for the site environmental remediation and clean up on the basis of the cost estimation provided in the remediation plan submitted by the Delegated Commissioner, plus additional compensation amounting to a preliminary estimate of euro 800 million relating to environmental damage, estimated increases in the regional health expenditures and damage to the public image to be fairly determined during the civil proceeding. The Council of Ministers, the Ministry for the Environment and the Delegated Commissioner is claiming compensation amounting to euro 129 million for the site environmental remediation and clean up (this request is analogous to that of the Calabria Region) and eventual compensation for other environmental damage to be fairly determined during the civil proceeding. In February 2007 the Ministry for the Environment filed with the Court an independent appraiser’s report issued by APAT that estimated a refundable environmental damage amounting to euro 1,920 million, including the remediation and clean up expenditures, increased by euro 1,620 million from the original amount of euro 129

F-80

##### Table of Contents

million, and an estimation of environmental damage and other damage items amounting approximately to euro 300 million. The amounts estimated by the independent appraiser, added to the claim of the Calabria Region, generate a total of euro 2,720 million of potential compensation. In May and September 2007 Syndial presented its own technical advice that, based on what the Company believes to be well-founded circumstances, vigorously object the independent appraiser’s findings filed by the Ministry for the Environment on site contamination, the responsibility of Syndial in the contamination of the site, the criteria of estimate remediation costs, which according to the Company are erroneous, arbitrary and technically inadequate. On October 7, 2009 an independent appraiser report was filed that reviewed the environmental status of the site and estimated the remediation costs while the estimate of both the health damage caused by the pollution and the environmental damage would be issued in a further independent appraiser report. The findings of the independent appraisers are substantially in line with the issues expressed by Syndial on the measures for the environmental remediation and clean up, based on a risk analysis aimed to define effective and specific actions. The clean up project, approved to a great extent by the Ministry for the Environment and the Calabria Region, has been considered substantially adequate. The independent appraisers affirmed the necessity of clean up measures that were not planned by Syndial on one of the external areas (the so-called archaeological area) and considered being unnecessary the dredging of sea sediments. The estimated clean up costs are in line with the estimate made by Syndial. The independent appraiser report is less favorable to Syndial because it identifies as source of the contamination the production slag management, even recent. The independent appraiser report evaluated that the production technology was a BAT (Best Available Technology), instead the slag treatment could be performed in a more respectful way for the environment and the products (the so-called Cubilot) lacked the physic-chemical characteristic of stability that would avoided the emission of polluting agents in the soil. As regards the quantification of the environmental damage different by the remediation, the independent report APAT provided by the Ministry for the Environment quantified the damage for the lack of fruition of the site basing on the remediation costs that were significantly reduced by the independent appraiser report. In case the Judge resolves on the responsibility of Syndial in the contamination of the site based on the conclusions of the independent appraiser report, the Company could be liable, for the environmental damage different from the goods fruition (damage to the community, increases in the regional health expenditures), at least in part and as far as the damage is actually probed. On November 14, 2009, Syndial filed its objections to the independent appraiser report, sharing the conceptual model adopted by the independent appraiser report but demonstrating that the site contamination should be charged mainly to past management of the pollution slag on part of other operators that operated the site until the ’70s. On November 11, 2009 the Calabria Region filed its objection to the independent appraiser report affirming that the environmental damage to the surrounding areas of the site has not been assessed by the independent appraisers. The hearing for the review of the independent appraiser report and of the parts objections, assigned to another Judge, took place on April 13, 2010. During the hearing the Calabria Region required the revise of the independent appraiser report. The Judge rejected the request. As regards the ascertainment of the existence of a residual environmental damage not remedied by the clean up activities, the Board State of lawyers on behalf of the Ministry for the Environment requested an evaluation of the impact of the new regulation on the above mentioned damage. Syndial filed a document explaining the modification of the environmental damage regulation. The Judge scheduled the deadline for the filing of the counterparts’ objections to such document for September 16, 2010, and September 30, 2010 for the submission of Syndial reply. The findings related to the modification of the Environmental Damage regulation introduced by the Article 5-bis of the Law Decree No. 135/2009 submitted by all the parties will be discussed in the next hearing scheduled for November 17, 2010.
On September 15, 2010, the Calabria Region submitted a memorandum objecting to the documents filed by Syndial in the hearing of April 13, 2010. In September 30, 2010 Syndial filed a memorandum on the impact of the new Italian regulation about the environmental damage as per Law Decree No. 135/2009 on the proceeding. As a result of the discussions occurred between the parties, in the hearing held November 17, 2010 the Judge took under advisement the decision. With the act of December 21, 2010, the Judge deemed the acquired elements sufficient for the closing of the proceeding. The hearing for the final decision has been postponed to November 16, 2011 for the filing of the outcome.
However, discussions have been going on in order to arrange for a possible transaction of all environmental claims pending on this matter. In 2008 Eni’s subsidiary Syndial took charge of performing certain clean up activities and on December 5, 2008 presented a global project to clean up and remediate all interested areas. As for the approval procedure of the above mentioned project all interested parties approved the removal of the dump from the seafront to another area, the construction of an hydraulic barrier and of the related treatment plant of the groundwater (providing that if the subsequent monitoring would demonstrate the efficiency of the plant, Eni’s subsidiary would build up a physical barrier in the seafront) and the start-up of the first lot of activities on the soil through in situ technologies on condition that all the waste present in the areas, recognized after a specific inspection. Initially, the environmental provision made by Syndial in its financial statements amounted to euro 103 million based on the cost estimation of the original clean up project, as the Eni’s subsidiary believes to have no responsibility for the environmental damage considering the limited period during which it conducted industrial activities in the site and the Delegated Commissioner responsibility for not having properly managed the site clean up activities. In the Annual Report 2008, Eni increased the environmental provision by euro 154 million bringing the total amount of the environmental provision related to the clean up project to euro 257 million. The provision doesn’t cover the entire amount of clean up project expenses (euro 300 million) considering the circumstance that it

has been only partially approved. The environmental provision made by the company is progressively employed in the execution of the clean up activities. It must be noted that in 2003 the Delegated Commissioner for Environmental Emergency, Calabria Region and Province of Crotone presented a first claim for the payment of damages. With a decision in May 2007, the Court of Milan declared the invalidity of the power of proxy conferred to the Delegated Commissioner to act on behalf of the Calabria Region with the notice served to Syndial SpA and decided the liquidation of expenses born by the defendant. The appeal against that decision is pending. Syndial, the Province of Crotone and Council of Ministers filed their pleadings and subsequently the final statements of the case as well as memorandum of objections.
On January 20, 2011 the Appeal Court of Milan sentenced (Sentence 143/2011), fully accepting Syndial objections, the rejections of the claims made by the Council of Ministers, Ministry for the Environment, Delegated Commissioner for Calabria Region and Province of Crotone. The Appeal Court confirmed the invalidity of the entire proceeding accepting also an objection issued by Syndial on the inadmissibility of the request of fractionate damage that is already under examination by another Judge. The Appeal Court condemned the counterparts to reimburse the legal expenses sustained by Syndial.
The claims made in this first instance were substantially absorbed in the above mentioned two proceedings.

(iv) Summon for alleged environmental damage caused by DDT pollution in the Lake Maggiore – Prosecuting body: Ministry for the Environment. With a temporarily executive decision dated July 3, 2008 the District Court of Turin sentenced the subsidiary Syndial SpA (former EniChem) to compensate for environmental damages that were allegedly caused when EniChem managed an industrial plant at Pieve Vergonte during the 1990-1996 period. Specifically, the Court sentenced Syndial to pay the Italian Ministry for the Environment compensation amounting to euro 1,833.5 million, plus legal interests that accrue from the filing of the decision. Syndial and Eni technical-legal consultants have considered the decision and the amount of the compensation to be without factual and legal basis and have concluded that a negative outcome of this proceeding is unlikely. Particularly, Eni and its subsidiary deem the amount of the environmental damage to be absolutely ill-founded as the sentence has been considered to lack sufficient elements to support such a material amount of the liability charged to Eni and its subsidiary with respect to the volume of pollutants ascertained by the Italian Environmental Minister. On occasion of the 2008 consolidated financial statements, management confirmed its stance of making no loss provision for this proceeding on the basis of the above mentioned technical legal advice, in concert with external consultants on accounting principles. In July 2009, Eni’s subsidiary Syndial filed an appeal against the above mentioned sentence, also requesting suspension of the sentence effectiveness. The Ministry for the Environment, in the appeal filed, requested to the Second Instance Court to adjust the first degree sentence condemning Syndial to the payment of euro 1,900 million or alternatively euro 1,300 million in addition to the amount assessed by the First Degree Court. In the hearing on December 11, 2009, the Second Instance Court considering the modification of Environmental Damage regulation introduced by the Article 5-bis of the Law Decree No. 135/2009 and following a request of the Board of State lawyers decided the postponement to May 28, 2010, pending the Decree of the Ministry for the Environment related to the determination of the quantification criteria for the monetary compensation of the environmental damage pursuant to the above mentioned Article 5-bis of the Law Decree No. 135/2009. The Board of State lawyers committed itself to not examine the sentence until the next hearing.
In the hearing of May 28, 2010, Syndial requested a further postponement still pending the above mentioned Decree of the Ministry for the Environment. The Board of State lawyers agreed to the request, justifying he postponement with the negotiation in place between the parties for the global solution of the proceeding, committing itself to not examine the sentence until the next hearing.
The Judge decided the postponement to October 29, 2010. In this hearing the Judge, since parties were still negotiating an environmental transaction, postponed the hearing to January 29, 2011. That hearing has been rescheduled to September 30, 2011 as discussions are ongoing.
Another administrative proceeding is ongoing regarding a ministerial decree enacted by the Italian Ministry for the Environment. The decree provides that Syndial executes the following tasks: (i) the upgrading of a hydraulic barrier to protect the site; and (ii) the design of a project for the environmental remediation of Lake Maggiore. The Administrative Court of Piemonte rejected Syndial’s opposition against the outlined environmental measures requested by the Ministry for the Environment. However, the Court judged the prescriptions of the Ministry regarding the remediation of the site to be plain findings of an environmental enquiry to ascertain the state of the lake. Syndial has filed an appeal against the decision of the Court before an upper degree body, also requesting suspension of the effectiveness of the decision. The appeal has been put on hold considering that a plan to ascertain the environmental status of the site has been approved by all interested parties, including the Ministry and local municipalities pursuant to the statement on April 28, 2009, which included certain recommendations. Syndial appealed against this statement and the related ministerial decree of approval in order to avoid the case to give implicit consent to the request (appealed by the Company) of the Minister that claimed that Syndial is obliged to execute the clean up. On the contrary, Syndial has agreed on the scope of the plan to ascertain the environmental status of the site, as it has been actually implementing it. Syndial also presented a clean up project for the groundwater and the soil, that hasn’t been approved, as the above mentioned prescriptions that have been prescribed are the object of the Company opposition in the above mentioned proceeding. In case Syndial should be found guilty, it would incur remediation and clean up expenses, actually not quantifiable, that would be offset against any

compensation for the environmental damage that Eni’s subsidiary is condemned to pay with regard to civil proceeding pending before the Second Instance Court of Turin.

(v) Action commenced by the Municipality of Carrara for the remediation and reestablishment of previous environmental conditions at the Avenza site and payment of environmental damage. The Municipality of Carrara commenced an action before the Court of Genova requesting Syndial SpA to remediate and restore previous environmental conditions at the Avenza site and the payment of unavoidable environmental damage (amounting to euro 139 million), further damages of various types (e.g. damage to the natural beauty of this site) amounting to euro 80 million as well as damages relating to loss of profit and property amounting to approximately euro 16 million. 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 for 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. Syndial summoned Rumianca SpA, Sir Finanziaria SpA and Sogemo SpA, who ran the plant in previous years, in order to be guaranteed. A report produced 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. With a sentence of March 2008, the Court of Genova rejected all claims made by the Municipality of Carrara and the Ministry for the Environment. Both plaintiffs filed an appeal against this decision in June 2008 confirming the requests issued in the first judgment. Syndial filed in the appeal hearing, disputing the plaintiffs’ claims. The proceeding is underway without any further investigation. The hearing has been postponed to July 2010 for the filing of the pleadings. In this hearing the parties filed their pleadings and the Judge postponed the hearing for the final decision to October 6, 2011.

(vi) Ministry for the Environment – Augusta harbor. The Italian Ministry for the Environment with various administrative acts prescribed 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, Syndial and Eni R&M. 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. The above mentioned companies opposed said administrative actions, objecting in particular to the way in which remediation works have been designed and information on concentration of pollutants has been gathered. The Regional Administrative Court of Catania with the Sentence No. 1254/2007 annulled the said decisions. The Ministry and the Municipalities of Augusta and Melilli filed a claim for the revocation of the decision and requested the suspension of sentence effectiveness with the Administrative Council of the Sicily Region which accepted the claim. The recommendations which the Council’s decision related, have been restated by the Ministry for the Environment with further administrative resolutions that have been appealed by the Eni companies. Again the Regional Administrative Court of Catania reiterated its decision to suspend the effectiveness of the Ministry’s acts. In January 2008 the Regional Court of Catania accepted further claims on this matter. In June 2008 the Ministry for the Environment and the Municipalities of Melilli and Augusta filed an appeal against the decision of the Regional Court of Catania with the Administrative Council of the Sicily region, without a resolution of the issue of suspending the effectiveness of the Regional Court’s decisions. The hearing for the examination of both appeal pending with the Administrative Council of the Sicily Region that has been originally scheduled on December 11, 2008, has been postponed sine die due to preliminary issues pending with the Court of Justice of the European Community. In April 2008, the Eni companies challenged certain administrative acts of December 20, 2007 related to the execution of further clean up and remediation works of sediments in the Augusta harbor. In this proceeding the Regional Court of Catania has ordered an independent appraiser report, issued on February 20, 2009, that resulted favorable to the objections of the objecting companies. The proceeding is pending. In May 2008, the Eni companies also challenged with the Regional Court of Catania, requesting the suspension of administrative act effectiveness, certain decisions of an Administrative Body on March 6, 2008 (and other subsequent decisions). Those decisions were intended to enlarge the scope of the already approved project of environmental remediation and clean up of the groundwater trough works of physic limitation and the new criteria used by the Administration Body in the restitution of the areas to their legitimate use. With regard to this last proceeding, basing on a request of the appealing companies, the Regional Court of Catania requested the decision of the Court of Justice of EU to decide on the correct application of the community principle, that represent the basis for the all appeals’ decision particularly the principles of the liability associated with the environmental damage, the proportionality in bearing the expenditures associated with environmental remediation and clean up, as well as a criteria of reasonableness and diligent execution in remedying an environmental damage. On March 9, 2010, the European Court gave a sentence that basically represented a favorable outcome for Eni’s subsidiaries involved in the matter. Specifically, the European Court confirmed the community principle of the liability associated with the environmental damage, whereby central to its correct interpretation is the relation between cause and effect and the identification of the entity that is actually liable for polluting. In the hearing of October 21, 2010, the Court upheld the appeals filed by the counterparts while the filing of the Court’s decisions is still pending.
It must be noted that the Public Prosecutor of Siracusa commenced a criminal action against an unknown party in order to verify the effective contamination of the Augusta harbor and the connected risks on the execution on the

F-83

##### Table of Contents

clean up project proposed by the Ministry. The technical assessment disposed by the Public Prosecutor generated the following outcomes: (a) no public health risk in the Augusta harbor; (b) absence of any involvement on part of Eni companies in the contamination; and (c) drainages dangerousness. Based on those findings, the Public Prosecutor decided to dismiss the proceeding.

ENI SPA
(vii) Reorganization procedure of the airlines companies Volare Group, Volare Airlines and Air Europe – Prosecuting body: Delegated Commissioner. In March 2009 Eni and its subsidiary Sofid (now Eni Adfin) were notified of a bankruptcy clawback as part of a reorganization procedure filed by the airlines companies Volare Group, Volare Airlines and Air Europe which commenced under the provisions of Ministry of Production Activities, on November 30, 2004. The request regarded the override of all the payments made by those entities to Eni and Eni Adfin, as Eni agent for the receivables collection, in the year previous to the insolvency declaration from November 30, 2003 to November 29, 2004, for a total estimated amount of euro 46 million plus interest. Eni and Eni Adfin were admitted as defendants and the trial has been postponed. Eni accrued a risk provision with respect to this proceeding.

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. 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 and Terni Industrie Chimiche SpA (both merged into Syndial). 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 liquidation, claiming for the reimbursement of the amount paid to Serfactoring and not liquidated to Agrifactoring by Federconsorzi. Syndial and Serfactoring filed 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 was subsequently reduced to euro 46 million following partial payment of the original receivables by the liquidator of Federconsorzi and various setoffs. These proceedings, which were unitized, were decided with a partial judgment, deposited on February 24, 2004; the request of Agrifactoring – that was reduced by an independent accounting consultant to the amount of euro 42.3 million – was rejected and the company was ordered to pay the sum requested by Serfactoring and Syndial to be determined following the decision. Agrifactoring appealed this decision and in June 2008, the trial was decided with a partial judgment that, reforming the previous judgment of the Court of Rome, granted the requests of Agrifactoring and ordering Serfactoring to reimburse Agrifactoring the sum paid by the latter to the former and not refunded by Federconsorzi. The Court resolved to charge an independent accounting consultant with quantifying the total amount paid by Agrifactoring to Serfactoring and the amount paid by Federconsorzi to Agrifactoring in order to determine the sum to be reimbursed to Agrifactoring.
On September 28, 2010, the independent accounting consultant filed the determination of the charge pertaining to Serfactoring amounting to euro 48.98 million, net of the payment made by Federconsorzi to Agrifactoring. Syndial and Serfactoring submitted a written reply objecting to this conclusion. In the hearing of October 28, 2010, Eni’s companies requested the independent accounting consultant clarify the criteria of determination of the above mentioned charge. The Court approved the request and rescheduled the hearing to February 24, 2011, ordering the independent accounting consultant to submit a written report. In that hearing the consultants filed their reports and the hearing for the filing of the pleadings has been scheduled for April 28, 2011.
Serfactoring and Syndial (as precautionary measure, since they have already filed a preliminary appeal) appealed the above mentioned partial sentence of 2008 of the Second Instance Court of Rome with an upper degree Court. Agrifactoring in turn filed counterclaim, requesting the declaration of inadmissibility or the rejection of the appeal. Eni accrued a provision with respect to this proceeding.

SAIPEM SPA
(ii) CEPAV Uno and CEPAV Due. Saipem holds interests in the CEPAV Uno (50.36%) and CEPAV Due (52%) consortia that in 1991 signed two contracts with TAV SpA (now RFI - Rete Ferroviaria Italiana 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 a claim amounting to euro 800 million then increased to euro 1,770 million. CEPAV Uno and TAV failed to solve this dispute amicably. CEPAV Uno opened an arbitration procedure as provided for under terms of the contract on April 27, 2006.
The preliminary investigation of the arbitration procedure is still pending. On July 30, 2010, the independent consultants filed their finding that resulted partially favorable to the Company and in the subsequent hearings the counterparts filed their motion on preliminary issues and the related objections. In the next hearing of March 20, 2011, the independent consultants would fill further reports on the above mentioned issue.
The deadline for the submission of the arbitration determination has been scheduled for December 27, 2011.
On March 23, 2009, the Arbitration Committee determined the TAV right to extend the assessment made by the independent accounting consultant to the subcontractors appointed by the Consortium, the contractors, or assignees. Basing on the alleged invalidity of Arbitration Committee determination, on April 8, 2010, the Consortium notified to the counterparts the appeal to this decision requesting its suspension before the Appeal Court of Rome.
With regard to the project for the construction of a high-speed railway 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, commenced on December 28, 2000, requested by CEPAV Due against TAV for the recognition of costs incurred by the Consortium in the ten-year period from 1991 through 2000 plus damages suffered, in January 2007, the Arbitration Committee determined the Consortium’s right to recover the costs incurred in connection with the design activities performed. The technical independent survey to assess the amount of compensation was submitted on October 19, 2009. The trial ended on February 23, 2010, with the resolution of the arbitration that required TAV to pay to CEPAV Due Consortium an amount of euro 44,176,787 plus legal interest and compensation for inflation accrued from the submission of the arbitration until the date of effective damage payment; the Court also required TAV to pay euro 1,115,000 plus interest and compensation for inflation accrued from October 30, 2000 until the date of effective damage payment. TAV filed with the Second Instance Court of Rome an appeal against the partial arbitration committee’s determination of January 2007. In February 2007, the Consortium CEPAV Due notified to TAV a second request of arbitration following the Decree No. 7 of December 31, 2007, that revoked the concessions awarded to TAV resulting in the annulment of arrangements signed between TAV and the Consortium to build the high-speed railway section from Milan to Verona. The European Court of Justice was requested to rule on this matter. Subsequently, Law No. 133/2008 reestablished the concessions awarded to TAV resulting in the continuation of the arrangements between the Consortium CEPAV Due and a new entity in charge of managing the Italian railway system. The second arbitration proceeding continued in order to determinate the damages suffered by the Consortium even in the period prior to the revocation of the concession. An independent appraiser has been appointed in order to assess those damages. The arbitration proceeding is suspended, since the negotiations between the parties in order to sign the integration to the existing agreement and to settle the arbitration already closed and the pending one are underway. The deadline for the submission of the arbitration determination was for December 31, 2010.

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

3.1 Antitrust

ENI SPA
(i) Abuse of dominant position of Snam alleged by the Italian Antitrust Authority. In March 1999, the Italian Antitrust Authority concluded its investigation started in 1997 and: (i) found 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 for euro 2 million; and (iii) ordered a review of the 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 No. 1998/30/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) European Commission’s investigations on players active in the natural gas sector. In the context of its initiatives aimed at verifying the level of competition in the natural gas sector within the European Union, on March 2009, Eni received a statement of objections by the European Commission relating to a proceeding under Article 82 EC and Article 54 of the EEA Agreement and concerning an alleged unjustified refusal to grant access to the TAG (Austria), TENP/Transitgas (Germany/Switzerland) pipelines, connected with the Italian gas transport system. On February 4, 2010, Eni, reaffirming the legitimacy of its activity, filed with the European Commission a number of structural remedies with a view to resolving the proceeding without the ascertainment of the illicit behavior and consequently without sanctions. Eni has committed to dispose of its interests in the German TENP, in the Swiss Transitgas and in the Austrian TAG gas pipelines. Given the strategic importance of the Austrian TAG pipeline, which transports gas from Russia to Italy, Eni has negotiated a solution with the Commission which calls for the transfer of its stake to an entity controlled by the Italian State. On September 29, 2010, the European Commission issued a decision whereby it resolved to accept Eni’s commitments and made them mandatory. The Commission acknowledged that its intervention was unwarranted and closed the proceeding. Eni is currently adopting all procedures to execute those commitments in accordance with such time schedule and criteria which have been agreed upon with the Commission (a non confidential version of the final agreements is available at the Company web site http://www.eni.com/it_IT/azienda/attività-strategie/gas-power/trasporto-gas/trasporto.shtml).

(iii) Trans Tunisian Pipeline Co Ltd (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 behavior 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 including the upgrade of the 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. Pending this development, the payment of the fine has been voluntarily suspended. In 2007, the Regional Administrative Court of Lazio accepted in part Eni’s claim and cancelled the quantification of the fine based on the Antitrust Authority’s inadequate evaluation of the circumstances presented by Eni. Eni filed an appeal with the Council of State, as did the Antitrust Authority and TTPC.
On May 27, 2010, the Italian Antitrust Authority notified Eni the start of a proceeding aimed at reappraising the criteria that were applied in the initial determination of the fine amounting to euro 290 million, in accordance with a resolution of the Regional Administrative Court of Lazio made on February 15, 2006.
On December 20, 2010, the Council of State sentenced (Sentence No. 9306) to reform the original resolution of the Italian Antirust Authority of February 2006 as regards the quantification of the fine reducing it to euro 20,405,000. On January 4, 2011 Eni paid the reduced amount, since the procedure of the Italian Antitrust Authority to reappraise the amount of the fine was overruled by the decision of the Council of State on the same issue.

(iv) Italian Antitrust Authority’s inquiry in the distribution and selling of gas in the retail sector. On May 7, 2009, the Italian Antitrust Authority, based on complaints sent by the company Sorgenia, started a preliminary investigation against various operators engaging in the gas retail market in Italy by means of integrated operations in both gas distribution via local low-pressure network and gas marketing to retail customers in urban areas, among them the Company and its fully-owned subsidiary Italgas. The investigation targets an alleged abuse of dominant position in the gas retail market in Italy associated with commercial practices intended to make it difficult for retail customers consuming less than 200,000 CM/y to change the supplier. According to the Italian Antitrust Authority, these commercial practices would enable selling companies that belong to integrated group companies to preserve their market shares in the areas operated by group’s distributors. On March 24, 2010, the Antitrust Authority published on its website the commitments of Italgas and other distribution companies involved in this inquiry, as foreseen by Article 14-ter of the Law No. 287/1990. These commitments were intended to remedy the alleged anti-competitive practices charged by the Authority, starting the market test phase. On September 8, 2010, the Italian Antirust Authority sentenced (Sentence No. 21530) to accept and make mandatory the remedies issued by Italgas. The proceeding was resolved without the ascertainment of the illicit behavior and without any fine to Eni and Italgas.

(v) Italian Antitrust Authority’s inquiry in the selling of bitumen. On May 27, 2010, the Italian Antitrust Authority started a preliminary investigation against Eni and other eight companies engaging in marketing bitumen for road by means of an agreement intended to hamper competition in this sector in Italy, in breach of Article 101 of Treaty on the Functioning of the European Union. The investigation is in the preliminary phase. The deadline for the finalization of the preliminary investigation has been scheduled for November 25, 2011.

ENI SPA, POLIMERI EUROPA SPA AND SYNDIAL SPA
(vi) Inquiries in relation to alleged anti-competitive agreements in the area of elastomers – Prosecuting Body: European Commission. In December 2002, inquiries were commenced concerning alleged anti-competitive agreements in the field of elastomers. The most important inquiry referred to BR and ESBR elastomers which was finalized on November 29, 2006, when the Commission fined Eni and its subsidiary Polimeri Europa for an amount of euro 272.25 million. Eni and its subsidiary filed claims against this decision before the European Court of First Instance in February 2007. The hearings took place in October 2009 and the filing of the Court’s decisions is still pending. Pending the outcome, Polimeri Europa presented a bank guarantee for euro 200 million and paid the residual amount of the fine. In August 2007, with respect to the above mentioned decision of the European Commission, Eni submitted a request for a negative ascertainment with the Court of Milan aimed at proving the non-existence of alleged damages suffered by tire BR/SBR manufacturers. The Court of Milan declared the appeal inadmissible appealing against a sentence of the District Court of Milan. The sentence for the appeal is still pending. Eni accrued a risk provision with respect to this proceeding.

3.2 Regulation

(i) Distribuidora de Gas Cuyana SA. Formal investigation of the agency entrusted with the regulations for the natural gas market in Argentina. Enargas started a formal investigation on some operators, among them Distribuidora de Gas Cuyana SA, a company controlled by Eni. Enargas stated that the company improperly applied 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. In April 2004, the company filed a defensive memorandum. On April 28, 2006, the company formally requested the acquisition of documents from Enargas in order to have access to the documents on which the allegations are based.

(ii) Preliminary investigation of the Authority for Electricity and Gas on the application of the regulation on the issue of the transparency of invoices. On September 25, 2009 the Authority for Electricity and Gas sentenced (Sentence VIS 93/2009) to commence a preliminary investigation against 5 marketing companies in the electricity sector, including Eni, to ascertain the eventual violation of the regulation on the issue of the transparency of the invoices (Resolutions 152/2006, 156/2007 and 272/2007) and to eventually impose administrative monetary penalties.
On May 5, 2010, the Authority communicated to the Company the results of the preliminary investigation: the Authority believes that the alleged violations have been committed and are still ongoing as of the date of the communication. In addition the Authority reaffirmed the need to issue an instruction to the Company to execute certain remedial actions as announced at the commencement of the investigation. Eni replied to the Authority that prior to the beginning of the preliminary investigation, in July 2009, the Company modified the layout of its invoices, which the Company believes to be fully compliant with transparency obligations set by the current regulation (providing also further information for an higher level of transparency for the client). The Company also believes that its invoice lay-out largely anticipates the new regulation on the issue of harmonization of invoices (Resolution 202/2009). Eni accrued a provision with respect to this proceeding even if the company considers to have demonstrated to have substantially complied with the applicable regulation. On October 11, 2010, the Authority for Electricity and Gas imposed (Sentence VIS 110/2010) a fine amounting to euro 350,000 of which: (i) euro 200,000 related to residential customers; and (ii) euro 150,000 related to non-residential customers connected in low voltage. Eni paid the sanction and filed a claim before the Regional Administrative Court against the sentence in order to defend its rights and interests.

(iii) Preliminary investigation of the Authority for Electricity and Gas on the billing of the tariff balance to final gas clients and periodicity of the billing. On May 25, 2010, the Authority for Electricity and Gas sentenced (Resolution VIS 36/2010) to commence a preliminary investigation against Eni in order to: (i) fine the Company for the alleged infringement of the Resolution 229/2001 (regulating the contractual conditions of gas sale to final clients through the network of local gas lines), Resolution 42/1999 (referred to the invoices transparency), Resolution 126/2004 (related to the code of commercial behavior for the gas sale) and the Integrated Text on the regulation of the quality of marketing services of electricity and gas (Resolution ARG/com 164/2008); and (ii) adoption of decisions aimed at break up behaviors prejudicial to clients rights. The resolution that sentenced the commencement of the proceeding includes also a number of injunctions as well as requests for information and documents that Eni provided to the Authority. Eni filed a claim before the Regional Administrative Court of Lombardia against the Resolution VIS 36/2010.
On November 10, 2010, the Authority for Electricity and Gas communicated to Eni the conclusions of the preliminary investigation confirming the alleged violations and subsequently authorizing the start of a proceeding.

F-87

##### Table of Contents

In the final hearing of the Authority authorized the Company to file a defensive memorandum and subsequently filed a claim before the Regional Administrative Court against the conclusion of the preliminary investigations. Eni accrued a risk provision with respect to this proceeding even if the company considers its motivations to be well grounded in the appeal proposed against the Authority for Electricity and Gas.

4. Court Inquiries

(i) EniPower. In June 2004, the Milan Public Prosecutor commenced inquiries into contracts awarded by Eni’s subsidiary EniPower and on supplies from other companies to EniPower. These inquiries were widely covered by the media. 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 (now Saipem SpA) (contractor of engineering and procurement services) with notices of process in accordance with existing laws regulating the administrative responsibility of companies (Legislative Decree No. 231/2001). In its meeting of August 10, 2004, Eni’s Board of Directors examined the aforementioned 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 cooperate fully in every respect with the Court. From the inquiries performed, no default in the organization emerged, nor deficiency in internal control systems. External experts have performed inquiries with regard to certain specific aspects. In accordance with its transparency and firmness guidelines, Eni took 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 the administrative responsibility of companies (Legislative Decree No. 231/2001). In August 2007, Eni was notified that the Public Prosecutor requested the dismissal of EniPower SpA and Snamprogetti SpA, while the proceeding continues against former employees of these companies and employees and managers of the suppliers under the provisions of Legislative Decree No. 231/2001. Eni SpA, EniPower and Snamprogetti presented themselves as plaintiffs in the preliminary hearing. In the preliminary hearing related to the main proceeding on April 27, 2009, the Judge for the Preliminary Hearings requested all the parties that have not requested the plea-bargain to stand in trial, excluding certain defendants as a result of the statute of limitations. During the hearing on March 2, 2010, the Court confirmed the admission as plaintiffs of Eni SpA, EniPower SpA and Saipem SpA against the inquired parties under the provisions of Legislative Decree No. 231/2001. Further companies involved were identified as defendants. The proceeding continues with the examination of the witnesses.

(ii) Trading. An investigation is pending regarding two former Eni managers who were allegedly bribed by third parties in favor to 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 of two judicial measures for the seizure of documentation concerning Eni’s transactions with the said companies. Eni is acting as plaintiff in this proceeding. The Judge for the Preliminary Hearings rejected most of the dismissal requests issued by the Public Prosecutor. Basing on the decision of the Judge for the Preliminary Hearings, the Public Prosecutor of Rome notified Eni, as injured part, the summon against two former managers of the company charged of aggravated fraud related to the relevant patrimonial damage caused to the injured part through the abuse of working relations and activities. The first hearing, scheduled for January 27, 2010, was postponed to March 30, 2010.
In the hearing of March 30, 2010 Eni was admitted as plaintiff against all the defendants. Subsequently the legal defense of one of the former managers opted for the "non-conditioned" plea-bargain. The Judge removed this position from the main proceeding postponing the related hearing to the same date of the principal one. In the hearing of June 23, 2010 related to the position of a former manager of Eni, the Public Prosecutor, made a request of acquittal coherently with the previous request of dismissal of that defendant. Eni legal defense asked the conviction of the defendant. After the debate, in the hearing of July 13, 2010, the Court acquitted that defendant. The Court would file the grounds of the judgment within the next 90 days. In the same date the main proceeding for the definition of the preliminary investigation requests was postponed to the hearing of February 9, 2011, and subsequently to May 24, 2011.

(iii) TSKJ Consortium Investigations by U.S., Italian, and Other Authorities. Snamprogetti Netherlands BV has a 25% participation in the TSKJ Consortium companies. The remaining participations are held in equal shares of 25% by KBR, Technip, and JGC. Beginning in 1994 the TSKJ Consortium was involved in the construction of natural gas liquefaction facilities at Bonny Island in Nigeria. Snamprogetti SpA, the holding company of Snamprogetti Netherlands BV, was a wholly owned subsidiary of Eni until February 2006, when an agreement was entered into for the sale of Snamprogetti to Saipem SpA and Snamprogetti was merged into Saipem

F-88

##### Table of Contents

as of October 1, 2008. Eni holds a 43% participation in Saipem. In connection with the sale of Snamprogetti to Saipem, Eni agreed to indemnify Saipem for a variety of matters, including potential losses and charges resulting from the investigations into the TSKJ matter referred to below, even in relation to Snamprogetti subsidiaries. The U.S. Securities and Exchange Commission (SEC), the U.S. Department of Justice (DoJ), and other authorities, including the Public Prosecutor’s office of Milan, have made investigations about alleged improper payments made by the TSKJ Consortium to certain Nigerian public officials.

The proceedings in the U.S.: in 2010 a settlement of the proceeding was entered into with the U.S. Authorities investigating the matter (the U.S. DoJ and the U.S. SEC) following long and complex discussions which commenced in 2009. In July 2010, Snamprogetti Netherlands BV entered into a deferred prosecution agreement with the DoJ. Pursuant to the agreement, the DoJ filed charges against Snamprogetti Netherlands BV including a count of conspiracy and violating certain provisions of the U.S. Foreign Corrupt Practices Act. Snamprogetti Netherlands BV agreed to pay a criminal penalty of $240 million.
If it satisfies the terms of the agreement, the charges against Snamprogetti Netherlands BV will be dismissed. Eni and Saipem agreed to guarantee the obligations of Snamprogetti Netherlands BV towards the DoJ, considering the contractual obligations assumed by Eni to indemnify Saipem as a part of the divestment of Snamprogetti. In July 2010, Eni and Snamprogetti Netherlands BV also entered into a consent order with the SEC, in which they consent to the filing of a complaint and the entry of a final judgment that alleges that Eni and Snamprogetti violated certain sections of the Securities Exchange Act of 1934. Under the consent order, Eni and Snamprogetti jointly agreed to pay disgorgement to the SEC in the amount of $125 million. Eni paid the agreed amounts in July 2010. Eni, Saipem, and Snamprogetti cooperated with the U.S. authorities’ investigations. In the agreements, the SEC and DoJ did not require the implementation of any independent compliance monitor. Since the conduct at issue, Eni, Saipem, and Snamprogetti Netherlands BV have made substantial enhancements to their anti-corruption compliance programs, which monitor Eni and its subsidiaries’ compliance systems. Eni and its subsidiaries are committed to continuous improvements to their internal compliance program and policies.

The proceedings in Nigeria: basing on the action commenced by the Nigerian Authorities, on December 10, 2010 Snamprogetti Netherlands BV agreed on a settlement with the Federal Government of Nigeria in order to resolve the investigation made on the activities of Snamprogetti Netherlands BV as member of the TSKJ Consortium. The Federal Government of Nigeria had previously commenced a legal action against the TSKJ Consortium and the four consortium companies, including Snamprogetti Netherlands BV. The company reached an agreement entailing the payment of a criminal fine amounting to $30 million and the reimbursement of $2.5 million for the legal expenditures of the Federal Government of Nigeria, thus concluding the legal proceeding. The Federal Government of Nigeria renounced to prosecute any criminal and civil action, in any jurisdiction, against Snamprogetti, the parent companies and the subsidiaries. In the agreement the Nigerian Authorities recognized that the alleged behaviors ended on June 15, 2004.

The proceedings in Italy: beginning in 2004, the TSKJ matter has prompted investigations by the Public Prosecutor’s office of Milan against unknown persons. Since March 10, 2009, the Company has received requests of exhibition of documents from the Public Prosecutor’s office of Milan. The events under investigation cover the period since 1994 and also concern the period of time subsequent to the June 8, 2001 enactment of Italian Legislative Decree No. 231 concerning the liability of legal entities. A violation of Legislative Decree June 8, 2001, No. 231, can result in the confiscation of criminal profits in addition to administrative penalties. During the preliminary investigations, the preventive attachment of such profits and other precautionary measures are possible. On July 31, 2009, a decree issued by the Judge for the Preliminary Investigation at the Court of Milan was served on Saipem SpA (as legal entity incorporating Snamprogetti SpA). The decree set for September 22, 2009, a hearing in Court in relation to a proceeding ex Legislative Decree No. 231 of June 8, 2001 whereby the Public Prosecutor of Milan is investigating Eni SpA and Saipem SpA for liability of legal entities arising from offences involving international corruption charged to two former managers of Snamprogetti SpA. The Public Prosecutor of Milan requested Eni SpA and Saipem SpA to be debarred from activities involving – directly or indirectly – any agreement with the Nigerian National Petroleum Corp and its subsidiaries. The above mentioned hearing allowed Eni and Saipem to their own defenses before any decision was made on the requested disqualification. The events referred to the request of precautionary measures of the Public Prosecutor of Milan cover TSKJ Consortium practices during the period from 1995 to 2004. In this regard, the Public Prosecutor claims the inadequacy and violation of the organizational, management and control Model adopted to prevent those offences charged to people subject to direction and supervision. At the time of the events under investigation, the Company had adopted a code of practice and internal procedures with reference to the best practices at the time. Subsequently, such code and internal procedures have been improved aiming at the continuous improvement of internal controls. Furthermore, on March 14, 2008 Eni approved a new Code of Ethics and a new Model 231 reaffirming that the belief that one is acting in favor or to the advantage of Eni can never, in any way, justify – not even in part – any behaviors that conflict with the principles and contents of the Code.

##### Table of Contents

On November 17, 2009, the Judge for the Preliminary Investigation rejected the request of precautionary measures of disqualification filed by the Public Prosecutor of Milan against Eni and Saipem. The Public Prosecutor of Milan appealed the decision of the Judge for the Preliminary Investigation.
On February 9, 2010, the Judge of Re-examination dismissed as unfounded the appeal of the Public Prosecutor. In February 19, 2010, the Public Prosecutor of Milan filed an appeal with the Third Instance Court, asking for the cancellation of the above mentioned decision of the Judge of Re-examination.
In the hearing of September 30, 2010, the Third Instance Court examined the appeal of the Public Prosecutor of Milan against the Judge of Re-examination decision of rejection of precautionary measures of disqualification. In this hearing the above mentioned Court accepted the claim of the Public Prosecutor and cancelled the decision of the Judge of Re-examination. The Court decided that the request of precautionary measures be admissible according to Law Decree No. 231/2001 even in the case of international corruption.
On January 24, 2011, Eni was notified the schedule of the hearing before the Re-examination Court of Milan for the debate on the request of precautionary measures issued by the Public Prosecutor of Milan basing on the decision of September 30, 2010 of the Third Instance Court.
On February 18, 2011, the Public Prosecutor of Milan, with respect to the guarantee payment amounting to euro 24,530,580, even in the interest of Saipem SpA, renounced to contest the decision of rejection of precautionary measures of disqualification for Eni SpA and Saipem SpA issued by the Judge for the Preliminary Hearings. In the hearing of February 22, 2011, the Re-Examination Court, taking note of the above mentioned renounce, declared inadmissible the appeal of the Public Prosecutor of Milan and closed the proceeding related to the request of precautionary measures of disqualification for Eni SpA and Saipem SpA.
On November 3, 2010, the defense of Saipem was notified the conclusion of the investigations relating to the proceeding pending before the Court of Milan through a deed by which the Court evidenced the alleged violations made by the five former Snamprogetti SpA (now Saipem SpA) and Saipem SpA being the parent company of Snamprogetti. The deed does not involve the Eni Group parent company Eni SpA. The charged crimes involve alleged corruptive events that have occurred in Nigeria after July 31, 2004. It is also stated the aggravating circumstance that Snamprogetti SpA reported a relevant profit (estimated at approximately $65 million). On December 3, 2010, the defense of Saipem was notified the opening of a proceeding with the first hearing scheduled for December 20, 2010. This first hearing that took place before the Judge for the Preliminary investigation of the Court of Milan was dedicated to the exposition of the motivations of the Public Prosecutor while the defenses exposed their point on January 12, 2011. At the end of this hearing the Public Prosecutor requested to replicate to defense motivations. In the hearing of January 26, 2011, the Public Prosecutor requested five former workers of Snamprogetti SpA (now Saipem) and Saipem SpA (as legal entity incorporating Snamprogetti) to stand trial.
It must be noted that the Board of Directors of Eni and Saipem in 2009 and 2010, respectively, approved new guidelines and anti-corruption policies regulating Eni and Saipem management of the business. The guidelines integrated anti-corruption policies of the Company, aligning them to the international best practices, optimizing the compliance system and granting the highest respect of Eni, Saipem and their workers of the Code of Ethics, 231 Model and national and international anti-corruption policies.

(iv) Gas metering. On May 28, 2007, a seizure order (in respect to certain documentation) was served upon Eni and other Group companies as part of a proceeding brought by the Public Prosecutor at the Court of Milan. The order was also served upon five top managers of the Group companies in addition to third party companies and their top managers. The investigation alleges behavior which breaches Italian criminal law, starting from 2003, regarding the use of instruments for measuring gas, the related payments of excise duties and the billing of clients as well as relations with the Supervisory Authorities. The allegation regards, inter alia, the offense contemplated by Legislative Decree of June 8, 2001, No. 231, which establishes the liability of the legal entity for crimes committed by its employee in the interests of such legal entity, or to its advantage. Accordingly, notice of the commencement of investigations was served upon Eni Group companies (Eni, Snam Rete Gas and Italgas) as well as third party companies. On November 26, 2009, a notice of conclusion of the preliminary investigation was served to Eni’s Group companies whereby 12 Eni employees, also including former employees, are under investigation. The exceptions filed in the notice include: (i) violations pertaining to recognition and payment of the excise on natural gas amounting to euro 20.2 billion; (ii) violations or failure in submitting the annual statement of gas consumption and/or in the annual declarations to be filed with the Duty Authority or the Authority for Electricity and Gas; and (iii) a related obstacle which has been allegedly posed to the monitoring functions performed by the Authority for Electricity and Gas.

investigation related to the crime under the provisions of Article 40 (violations pertaining to recognition and payment of the excise on mineral oils) of Legislative Decree No. 504 of October 26, 1995. The companies were not notified the ending of the investigation because it excludes any charge of involving the administrative responsibility regulated by the Legislative Decree 231 of 2001.

The Eni subsidiary is currently waiting for a measure from the judicial authority to dismiss the matter.

(vi) Kazakhstan. On October 1, 2009, the Public Prosecutor of Milan requested a number of documents pursuant to Article 248 of the Penal Code.

The crime of "international corruption" mentioned in the said request of transmission of documents is sanctioned, in addition to the Italian criminal code, by Legislative Decree June 8, 2001, No. 231, which establishes the administrative responsibility of companies for crimes committed by their employees on their behalf. Eni commenced the collection of the documentation in order to rapidly fulfill the requests of the Public Prosecutor. The company has deposited in different phases the documents collected. The Company continues to fully collaborate with the Public Prosecutor providing also further documentation when available. On November 29, 2010, the Tributary Police of Milan requested to interview certain Eni managers in the field of the evolution on the management of contract assigned to Agip KCO to NCC and OIC consortia.

The Company continues to fully collaborate with the Public Prosecutor providing also further documentation when available.

5. Tax Proceedings

ITALY

ENI SPA
(i) Dispute for the omitted payment of the municipal tax related to oil platforms located in territorial waters in the Adriatic Sea. With a formal assessment presented by the Municipality of Pineto (Teramo) in December 1999, 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 which constitute municipal 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. 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. However, the Court overturned both judgments, declaring that a municipality can consider requesting a tax on real estate in the sea facing its territory and with the decision of February 2005 sent the proceeding to another section of the Regional Tax Commission in order to judge on the matters of the proceeding. This commission charged an independent consultant with assessing all the accounting/technical aspects of the matter. The independent consultant confirmed that Eni’s offshore installations lack any ground to be subject to the municipal tax that was claimed by the local Municipality. Those findings were accepted by the Regional Tax Commission with a ruling made on January 19, 2009, and filed on December 14, 2009. On January 25, 2011, the Municipality notified to Eni an appeal to the Third

##### Table of Contents

Instance Court for the cancellation of the above mentioned sentence. Also on December 28, 2005, also the Municipality of Pineto presented similar claims relating to the same Eni platforms for the years 1999 to 2004. The total amount requested was euro 24 million including interest and penalties. Eni filed a claim against this claim which was accepted by the First Degree Judge with a decision of December 4, 2007. Similar formal assessments related to Eni oil and gas offshore platforms were presented by the Municipalities of Falconara Marittima, Tortoreto, Pedaso, and also from 2009 the Gela Municipality. The total amounts of those claims were approximately euro 7.5 million. The company filed appeal against all those claims.

ENI SPA and ENIADFIN SPA
(ii) Assessments for Padana Assicurazioni tax returns. In November and December 2010, the Italian Tax Authorities issued an assessment for Padana Assicurazioni tax returns for the year 2005 and a pre-assessment for years 2006 and 2007. The Tax Authorities have denied certain cost deductions and assessed a greater value for the going concern transferred to Eni Insurance Ltd in 2007. The total claim amounted to euro 148.5 million for taxes, penalties and interests. According to the guarantee issued in 2008, related to the sale of Padana Assicurazioni shares to Helvetia SV AG, this additional tax burden is to be charged to the seller companies: Eni SpA for 26.75% and its subsidiary Eni Adfin SpA for 73.25%. Based on those assessments, a risk provision has been accrued in the consolidated financial statements.

(iii) Claims concerning unpaid taxes and relevant payment of interest and penalties. In July 2004, relevant Kazakh Authorities informed Agip Karachaganak BV and Karachaganak Petroleum Operating BV, shareholder and operator of the Karachaganak contract, respectively, on the final outcome of 2000 to 2003 tax audits. Both companies counterclaimed against the assessment and a preliminary agreement was reached on November 18, 2004. Final assessments have now been issued by the Kazakh Authorities, and payment has been made. The final amount assessed and paid was $39 million net to Eni; this figure included taxes and interest. The companies continue to dispute the assessments and reserve the right to engage in International Arbitration proceedings with the Kazakh Authorities.
In October 2009, Kazakh Tax Authorities conducted a complex tax audit of Agip Karachaganak BV Branch and Karachaganak Petroleum Operating BV Branch, for the period 2004-2007. In December 2009, the tax authorities issued Tax Audit Act and relevant Notification for the year 2004 but so far nothing has been finalized for the later years. The 2004 audit resulted in an assessment of $21.6 million relating to CIT and WHT ($0.3 million). These amounts are disputed and appeals have been submitted to the Higher Level Tax Authority. In March and October 2010, Kazakh Tax Authorities started the complex tax audits respectively for the year 2008 and 2009. On December 23, 2010, Agip Karachaganak BV Branch and Karachaganak Petroleum Operating BV Branch received Tax Audit Acts for the year 2005. The taxes assessed as reflected in 2005 Tax Audit Acts equal to US$ 207.4 million including penalties and administrative fines relating to CIT (US$ 205.9 million) and Withholding Tax and other taxes (US$ 1.5 million). All taxes assessed and penalties as well as administrative fines are subject to further appeal process at higher tax authority level in compliance with deadlines established in the tax and administrative legislation.
There is also a dispute in relation to certain unresolved items of expenditure incurred by the operating company Karachaganak Petroleum Operating BV which has led to the Kazakh Authorities making certain claims against the company on the base of audits performed relating to prior years 2003-2006.
In February 2011, Kazakh Authorities notified a claim also in relation to the 2007 cost recovery.
Parties are negotiating in order to settle the dispute.

(iv) Tax proceeding Eni Angola Production BV. In the first months of 2009 the Ministry of the Finance of Angola, following a fiscal audit commenced at the end of 2007, filed a notice of tax assessment for fiscal years 2002 to 2007 in which it objected to the deductibility of amortization charges recognized on assets in progress related to the payment of the Petroleum Income Tax that was made by Eni Angola Production BV as co-operator of Cabinda concession. The company filed an appeal against this decision with the Provincial Court of Luanda for all the years of the claim. The Court of First Instance declared that it lacked competence in judging the matter. The judgment is still pending before the Supreme Court. Eni accrued a provision with respect to this proceeding.

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 exploration and development activities and it is entitled to the productions realized. In Production Sharing Agreement 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 does not exceed twenty years and it is granted by the Ministry of Productive Activities to persons that are consistent with legislation requirements and that can demonstrate to be able to conduct a storage program that meets the public interest in accordance with the laws. In the Gas & Power segment the gas distribution activity is primarily conducted on the basis of concessions granted by local public entities, pending the decrees for the determination of minimum limits of over-municipal areas. At the expiration date of the concession, compensation is paid, 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. The law provides the grant of distribution service exclusively by tender, with a maximum length 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, all non-removable assets are transferred to the grantor of the concession.

Environmental regulations
Risks associated with the footprint of Eni’s activities on the environment, health and safety are described in "Item 3 – Risk Factors". In the future, Eni will sustain significant expenses in relation to compliance with environmental, health and safety laws and regulations and for reclaiming, safety and remediation works of areas previously used for industrial production and dismantled sites. In particular, regarding the environmental risk, management does not currently expect any material adverse effect upon Eni’s consolidated financial statements, taking account of ongoing remedial actions, existing insurance policies and the environmental risk provision accrued in the consolidated financial statements. However, management believes that it is possible that Eni may incur material losses and liabilities in future years in connection with environmental matters 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 for the Environment; (iii) new developments in environmental regulation; (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.

Emission trading
Legislative Decree No. 216 of April 4, 2006 implemented the Emission Trading Directive No. 2003/87/EC concerning greenhouse gas emissions and Directive No. 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 November 27, 2008, the National Committee for Emissions Trading Scheme (Ministry for the Environment-Mse) published the Resolution 20/2008 defining emission permits for the 2008-2012 period. Eni was assigned permits corresponding to 126.4 million tonnes of carbon dioxide (of which, 25.8 in 2008, 25.8 in 2009, 25.3 in 2010, 25.0 in 2011, 24.5 in 2012) and in addition to approximately 2.0 million of permits expected to be assigned with respect to new plants in the five-year period 2008-2012. Emission quotas of new plants include only those physically assigned and recorded in the emissions registry. Emissions of carbon dioxide from Eni’s plants were lower than permits assigned in 2010. Against emissions of carbon dioxide amounted to approximately 25.5 million tonnes, emission permits amounting to 25.9 million tonnes were assigned, determining a 0.4 million tonnes surplus. In addition to such surplus, a 0.3 million tonnes of permits (as increase in the availability of Eni) are to be included following the contract of Virtual

Power Plan GDF Suez Energia Italia, primarily assigned to cover the emissions of the EniPower plants. For this reason, the total surplus amounted to about 0.7 million tonnes.

Net loss from derivatives of euro 131 million (a net loss of euro 427 million and euro 4 million in 2008 and 2009, respectively) was primarily due to the recognition in the profit and loss account of the change in the fair value of those derivatives which cannot be recognized according to the hedge accounting under IFRS as they were entered into for amounts equal to the net exposure to exchange rate risk and interest rate risk, and as such, they cannot be referred to specific trade or financing transactions. The lack of these formal requirements to qualify these derivatives as hedging instruments under IFRS also entailed the recognition in profit or loss of negative currency translation differences on assets and liabilities denominated in currencies other than functional currency, as this effect cannot be offset by changes in the fair value of the related instruments.

Current income taxes of euro 1,315 million were in respect of Ires and substitute tax (euro 1,077 million) and Irap (euro 224 million) for Italian subsidiaries and foreign taxes (euro 14 million).

The effective tax rate was 55.4% (50.3% and 56.0% in 2008 and 2009, respectively) compared with a statutory tax rate of 39.6% (38.2% and 40.1% in 2008 and 2009, respectively) and calculated by applying a 34.0%19 tax rate (Ires) to profit before income taxes and 3.9% tax rate (Irap) to the net value of production as provided for by Italian laws.

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

(%) |  | 2008 |  | 2009 |  | 2010

Statutory tax rate |  | 38.2 |  |  | 40.1 |  | 39.6
Items increasing (decreasing) statutory tax rate: |  |  |  |  |  |  |
- higher foreign subsidiaries tax rate |  | 15.2 |  |  | 13.3 |  | 15.0
- impact pursuant to Law Decree No. 112 of June 25, 2008, the Budget Law 2008 and enactment of a renewed tax framework in Libya |  | (3.8 | ) |  | 2.4 |  |
- permanent differences and other adjustments |  | 0.7 |  |  | 0.2 |  | 0.8
|  | 12.1 |  |  | 15.9 |  | 15.8
|  | 50.3 |  |  | 56.0 |  | 55.4

The increase in the tax rate of foreign subsidiaries primarily related to a 16.1 percentage points increase in the Exploration & Production segment (17.1% and 16.1% in 2008 and 2009, respectively).

The impact pursuant to Law Decree No. 112/2008, the Budget Law 2008 and enactment of a renewed tax framework in Libya consisted of the following: in the 2009 (i) the equalization in Libya of the 2008 income taxes for euro 230 million following adjustments to the valorization criteria of revenues; (ii) a reduced deductibility in Italy of the cost of goods sold following the reduction in the gas volumes of inventories for euro 64 million; in the 2008 (iii) the utilization of deferred tax liabilities recognized on higher carrying amounts of year-end inventories of oil, gas and refined products stated at the weighted-average cost with respect to their tax base according to the last-in-first-out method (LIFO) (euro 528 million). In fact, pursuant to the Law Decree No. 112/2008 (become Law No. 133/2008), energy companies in Italy are required from 2008 to state inventories of hydrocarbons at the weighted-average cost for tax purposes as opposed to the previous LIFO evaluation and to recognize a one-off tax calculated by applying a special tax with a 16% rate on the difference between the two amounts. Accordingly, profit and loss benefited from the difference between utilization of deferred tax liabilities accrued on hydrocarbons inventories and the one-off tax (euro 229 million), for a total positive impact of euro 176 million, which consider previously applicable statutory tax rate (Ires) of 33% instead of 27.5% of the previous tax regime. This one-off tax will be paid in three annual installments of same amount, due from 2009 onwards; (iv) application of the Italian Budget Law for 2008 that provide an increase in limits whereby carrying amounts of assets and liabilities of consolidated subsidiaries can be recognized for tax purposes by paying a one-off tax calculated by applying a special rate of 6% (positive impact on profit and loss of euro 370 million; euro 290 million net of the special tax); (v) enactment of a renewed tax framework in Libya regarding oil companies operating in accordance with production sharing schemes. Based on the new provisions, the tax base of the Company’s Libyan oil properties has been reassessed resulting in the partial utilization of previously accrued tax liabilities of euro 173 million; and (vi) the impact of above mentioned Law Decree No. 112/2008 on energy companies calculated by applying statutory tax rate (Ires) of 33% pursuant to the Law Decree No. 112/2008 instead of the previously applicable statutory tax rate (Ires) of 27.5% (euro 94 million).

In 2010, permanent differences and other adjustments for 0.8 percentage points included: (i) as increase, the supplemental Ires pursuant to the Law No. 7 of February 6, 2009 (1.5 percentage points) and, as decrease, an untaxed income related to a favorable outcome of an antitrust proceeding (0.6 percentage points). For further information see in Note 27 – Provisions for contingencies. In 2009 permanent differences and other adjustments for 0.2 percentage points included: (ii) as increase, a charge amounting to euro 250 million related to the estimation of a fine for the TSKJ matter to the U.S. Authorities (for further information see Note 34 – Guarantees, commitments and risks); and (iii) as decrease, deferred tax assets accounted following an adjustment of the fiscal value to the carrying amount of oil and gas properties related to a reorganization of the Italian activities by paying a special tax and the partial deductibility of Irap of income taxes of previous years (euro 222 million).

(19) |  | Includes a 5.5% supplemental tax rate on taxable profit of energy companies in Italy (whose primary activity is the production and marketing of hydrocarbons and electricity and with annual revenues in excess of euro 25 million) effective from January 1, 2008 and a further 1% increase effective from January 1, 2009, pursuant to the Law Decree No. 112/2008 (converted in to Law No. 133/2008).

From February 22, 2011, liquids and natural gas production at a number of fields in Libya and supplies through the GreenStream pipeline have been halted as a result ongoing political instability and conflict. Facilities have not suffered any damage and such standstills do not affect Eni’s ability to ensure natural gas supplies to its customers. Eni is technically able to resume gas production at or near previous level once the situation stabilizes. The overall impact of the political instability and conflict in Libya on Eni’s results of operations and cash flows will depend on how long such instability and conflict will last as well as on their final outcome, which management is currently unable to predict. Eni’s oil and natural gas production as of end of March 2011, was flowing at a rate ranging from 70 to 75 KBOE/d down from the expected level of approximately 280 KBOE/d. Production is continuing to decline. Current production mainly consists of gas that is entirely delivered to local power generation plant.

Results of operations from oil and gas producing activities
Results of operations from oil and gas producing activities, represent only those revenues and expenses directly associated with 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.

Oil and natural gas reserves
Eni’s criteria concerning evaluation and classification of proved developed and undeveloped reserves follow Regulation S-X 4-10 of the U.S. Securities and Exchange Commission and have been disclosed in accordance with FASB Extractive Activities - Oil & Gas (Topic 932).

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible, from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that

renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price20 shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Net proved reserves exclude interests and royalties owned by others.

Proved reserves are classified as either developed or undeveloped.

Developed oil and gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well.

Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

Since 1991 Eni has requested qualified independent oil engineering companies to carry out an independent evaluation21 of part of its proved reserves on a rotational basis. The description of qualifications of the person primarily responsible of the reserve audit is included in the third party audit report22.

In the preparation of their reports, independent evaluators rely, without independent verification, upon information furnished by Eni with respect to property interest, production, current cost of operation and development, sale agreements, prices and other factual information and data that were accepted as represented by the independent evaluators. These data, equally used by Eni in its internal process, include logs, directional surveys, core and PVT (Pressure Volume Temperature) analysis, maps, oil/gas/water production/injection data of wells, reservoir studies technical analysis relevant to field performance, reservoir performance, long-term development plans, future capital and operating costs.

In order to calculate the economic value of Eni equity reserves, actual prices applicable to hydrocarbon sales, price adjustments required by applicable contractual arrangements, and other pertinent information are provided.

In 2010 Ryder Scott Company and DeGolyer and MacNaughton22 provided an independent evaluation of almost 28% of Eni’s total proved reserves as of December 31, 201023 confirming, as in previous years, the reasonableness of Eni’s internal evaluations.

In the three-year period from 2008 to 2010, 78% of Eni’s total proved reserves were subject to independent evaluation.

As of December 31, 2010 the principal properties not subjected to independent evaluation in the last three years are Karachaganak (Kazakhstan), Samburgskoye and Yaro-Yakhinskoye (Russia).

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 54%, 57% and 55% of total proved reserves as of December 31, 2008, 2009 and 2010, respectively, on an oil-equivalent basis.

Similar effects as PSAs apply to service and "buy-back" contracts; proved reserves associated with such contracts represented 2%, 2% and 3% of total proved reserves on an oil-equivalent basis as of December 31, 2008, 2009 and 2010, respectively.

(20) | i | Before 2009, year-end liquids and natural gas prices were used in the estimate of proved reserves.

Oil and gas reserve quantities include: (i) oil and natural gas quantities in excess of 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. Reserve volumes associated with oil and gas deriving from such obligation represent 0.1%, 0.3% and 0.6% of total proved reserves as of December 31, 2008, 2009 and 2010, respectively, on an oil-equivalent basis; (ii) volumes of natural gas used for own consumption; (iii) the quantities of natural gas produced to feed the Angola LNG plant; and (iv) 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 removed from proved reserves when sold.

Numerous uncertainties are inherent in estimating quantities of proved reserves, in projecting future productions and development expenditures. The accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and evaluation. The results of drilling, testing and production after the date of the estimate may require substantial upward or downward revisions. 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 relevant to the date when such estimates are made. Consequently, the evaluation of reserves could also significantly differ from actual oil and natural gas volumes that will be produced.

The following table presents yearly changes in estimated proved reserves, developed and undeveloped, of crude oil (including condensate and natural gas liquids) and natural gas as of December 31, 2008, 2009 and 2010.

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 for the year ended December 31, 2008 and the average prices during the years ended December 31, 2009 and 2010 to estimated future production of proved reserves. Future price changes are considered only to the 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.

F-118

##### Table of Contents

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 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 FASB Extractive Activities - Oil & Gas (Topic 932). 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, hydrocarbon resources other than proved reserves, anticipated changes in future prices and costs and a discount factor representative of the risks inherent in the oil and gas exploration and production activity.

The standardized measure of discounted future net cash flows by geographical area consists of the following:

|  | a) |  | opposition with respect to the acquisition of material shareholdings by entities affected by the shareholding limit as set forth in Article 3 of Decree-law No. 332 of May 31, 1994, converted with amendments into Law No. 474 of July 30, 1994, by which – as per Decree issued by the Minister of Treasury on October 16, 1995 – are meant those representing at least 3 per cent. of share capital with the right to vote at the ordinary shareholders’ meeting.
|  |  |  | The opposition is expressed within ten days of the date of the notice to be filed by the Board of Directors at the time request is made for registration in the shareholders’ register if the Minister considers that such an acquisition may prejudice the vital interests of the Italian State. Until the ten-day term is not lapsed, the voting rights and the non-asset linked rights connected with the shares representing a material shareholding may not be exercised. If the opposition power is exercised, through a duly motivated act in connection with the prejudice that may be caused by the operation to the vital interests of the Italian State, the transferee may not exercise the voting rights and the other non-asset linked rights connected with the shares representing a material shareholding and must sell said shares within one year. In case of failure to comply, the court, upon request of the Minister of Economy and Finance, will order the sale of the shares representing a material shareholding according to the procedures set forth in Article 2359-ter of the Civil Code. The act through which the opposition power is exercised may be challenged by the transferee before the Lazio Regional Administrative Court within sixty days as of its issue;

In order to allow the exercise of the above mentioned opposition power, Consob notifies the Minister of Economy and Finance of the relevant pacts or agreements notified to it pursuant to the aforementioned Article 122 of Legislative Decree No. 58 of February 24, 1998. The opposition power must be exercised within ten days of the date of the notice by Consob. Until the ten-day term has elapsed, the voting right and the other non-asset linked rights connected with the shares held by the shareholders who have subscribed the above mentioned pacts or agreements may not be exercised. If the opposition power is exercised through the issue of an act that shall be duly motivated in consideration of the prejudice that may be caused by these pacts or agreements to the vital interests of the Italian State, the shareholders pacts or agreements shall be null and void. If in the shareholders’ meetings the shareholders who signed shareholders’ pacts or agreements should behave as if those pacts or agreements disciplined by Article 122 of Legislative Decree No. 58 of February 24, 1998 were still in effect, the resolutions approved with their vote, if determining for the approval, may be challenged. The act through which the opposition power is exercised may be challenged by the shareholders who joined the above mentioned pacts or agreements before the Lazio Regional Administrative Court within sixty days;
|  | c) |  | veto power, duly motivated in relation to the effective prejudice to the interests of the Italian State, with respect to resolutions to dissolve the Company, to transfer the business, to merge, to demerge, to transfer the Company’s registered office abroad, to change the corporate purpose or to amend the By-laws cancelling or modifying the powers indicated in this Article.

FOREWORD

Eni1 is an internationally oriented industrial group which, because of its size and the importance of its activities, plays a significant role in the marketplace and in the economic development and welfare of the individuals who work or collaborate with Eni and of the communities where it is present.

The complexity of the situations in which Eni operates, the challenges of sustainable development and the need to take into consideration the interests of all people having a legitimate interest in the corporate business ("Stakeholders"), strengthen the importance to clearly define the values that Eni accepts, acknowledges and shares as well as the responsibilities it assumes, contributing to a better future for everybody.

For this reason the new Eni’s Code of Ethics ("Code" or "Code of Ethics") has been devised.

Compliance with the Code by Eni’s directors, statutory auditors, management and employees as well as by all those who operate in Italy and abroad for achieving Eni’s objectives ("Eni’s People"), each within their own functions and responsibilities, is of paramount importance – also pursuant to legal and contractual provisions governing the relationship with Eni – for Eni’s efficiency, reliability and reputation, which are all crucial factors for its success and for improving the social situation in which Eni operates.

Eni undertakes to promote knowledge of the Code among Eni’s People and the other Stakeholders, and to accept their constructive contribution to the Code’s principles and contents. Eni undertakes to take into consideration any suggestions and remarks of Stakeholders, with the objective of confirming or integrating the Code.

Eni carefully checks for compliance with the Code by providing suitable information, prevention and control tools and ensuring transparency in all transactions and behaviours by taking corrective measures if and as required.

The Watch Structure of each Eni company performs the functions of guarantor of the Code of Ethics ("Guarantor").

The Code is brought to the attention of every person or body having business relations with Eni.

(1) |  | "Eni" means Eni SpA and its direct and indirect subsidiaries, in Italy and abroad.

I. GENERAL PRINCIPLES: SUSTAINABILITY AND CORPORATE RESPONSIBILITY

Compliance with the law, regulations, statutory provisions, self-regulatory codes, ethical integrity and fairness, is a constant commitment and duty of all Eni’s People, and characterizes the conduct of Eni’s entire organization.
Eni’s business and corporate activities has to be carried out in a transparent, honest and fair way, in good faith, and in full compliance with competition protection rules.
Eni undertakes to maintain and strengthen a governance system in line with international best practice standards, able to deal with the complex situations in which Eni operates, and with the challenges to face for sustainable development.
Systematic methods for involving Stakeholders are adopted, fostering dialogue on sustainability and corporate responsibility.
In conducting both its activities as an international company and those with its partners, Eni stands up for the protection and promotion of human rights – inalienable and fundamental prerogatives of human beings and basis for the establishment of societies founded on principles of equality, solidarity, repudiation of war, and for the protection of civil and political rights, of social, economic and cultural rights and the so-called third generation rights (selfdetermination right, right to peace, right to development and protection of the environment).
Any form of discrimination, corruption, forced or child labor is rejected. Particular attention is paid to the acknowledgement and safeguarding of the dignity, freedom and equality of human beings, to protection of labor and of the freedom of trade union association, of health, safety, the environment and biodiversity, as well as the set of values and principles concerning transparency, energy efficiency and sustainable development, in accordance with International Institutions and Conventions.
In this respect Eni operates within the reference framework of the United Nations Universal Declaration of Human Rights, the Fundamental Conventions of the ILO – International Labor Organization – and the OECD Guidelines on Multinational Enterprises.
All Eni’s People, without any distinction or exception whatsoever, respect the principles and contents of the Code in their actions and behaviours while performing their functions and according to their responsibilities, because compliance with the Code is fundamental for the quality of their working and professional performance. Relationships among Eni’s People, at all levels, must be characterized by honesty, fairness, cooperation, loyalty and mutual respect.
The belief that one is acting in favor or to the advantage of Eni can never, in any way, justify – not even in part – any behaviours that conflict with the principles and contents of the Code.

II. BEHAVIOUR RULES AND RELATIONS WITH STAKEHOLDERS

1. ETHICS, TRANSPARENCY, FAIRNESS, PROFESSIONALISM

In conducting its business, Eni is inspired by and complies with the principles of loyalty, fairness, transparency, efficiency and an open market, regardless of the importance level of the transaction in question.
Any action, transaction and negotiation performed and, generally, the conduct of Eni’s People in the performance of their duties is inspired by the highest principles of fairness, completeness and transparency of information and legitimacy, both in form and substance, as well as clarity and truthfulness of all accounting documents, in compliance with the applicable laws in force and internal regulations.
All Eni’s activities have to be performed with the utmost care and professional skill, with the duty to provide skills and expertise adequate to the tasks assigned, and to act in a way capable to protect Eni’s image and reputation. Corporate objectives, as well as the proposal and implementation of projects, investments and actions, have to be aimed at improving the company’s assets, management, technological and information level in the long term, and at creating value and welfare for all Stakeholders.
Bribes, illegitimate favours, collusion, requests for personal benefits for oneself or others, either directly or through third parties, are prohibited without any exception.
It is prohibited to pay or offer, directly or indirectly, money and material benefits and other advantages of any kind to third parties, whether representatives of governments, public officers and public servants or private employees, in order to influence or remunerate the actions of their office.
Commercial courtesy, such as small gifts or forms of hospitality, is only allowed when its value is small and it does not compromise the integrity and reputation of either party, and cannot be construed by an impartial observer as aimed at obtaining undue advantages. In any case, these expenses must always be authorized by the designated managers as per existing internal rules, and be accompanied by appropriate documentation.
It is forbidden to accept money from individuals or companies that have or intend to have business relations with Eni. Anyone who receives proposals of gifts or special or hospitality treatment that cannot be considered as commercial courtesy of small value, or requests therefore by third parties, shall reject them and immediately inform their superior, or the body they belong to, as well as the Guarantor.
Eni shall properly inform all third parties about the commitments and obligations provided for in the Code, require third parties to respect the principles of the Code relevant to their activities and take proper internal actions and, if the matter is within its own competence, external actions in the event that any third party should fail to comply with the Code.

> > > > Pursuant to your request, we have conducted an independent evaluation to serve as a reserves audit of the net proved crude oil, condensate, liquefied petroleum gas (LPG), and natural gas reserves, as of December 31, 2010, of certain properties in Africa, Italy, and Rest of Europe owned by Eni S.p.A. (Eni). This evaluation was completed on March 17, 2011. Eni has represented that these properties account for 13 percent, on a net equivalent barrel basis, of Eni’s net proved reserves as of December 31, 2010, and that Eni’s net proved reserves estimates have been prepared in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the Securities and Exchange Commission (SEC) of the United States. We have reviewed information provided to us by Eni that it represents to be Eni’s estimates of the net reserves, as of December 31, 2010, for the same properties as those which we have independently evaluated.

> > > > Reserves included herein are expressed as net reserves as represented by Eni. Gross reserves are defined as the total estimated petroleum to be produced from these properties after December 31, 2010. Net reserves are defined as that portion of the gross reserves attributable to the interests owned by Eni after deducting interests owned by others.

> > > > Data used in this audit were obtained from reviews with Eni personnel, from Eni files, from records on file with the appropriate regulatory agencies, and from public sources. In the preparation of this report we have relied, without independent verification, upon such information furnished by Eni with respect to property interests, production from such properties, current costs of operation and development, current prices for production, agreements relating to current and future operations and sale of production, and various other information and data that were accepted as represented. A field examination of the properties was not considered necessary for the purposes of this report.

> > > > Methodology and Procedures

> > > > Estimates of reserves were prepared by the use of appropriate geologic, petroleum engineering, and evaluation principles and techniques that are in accordance with practices generally recognized by the petroleum industry as presented in the publication of the Society of Petroleum Engineers entitled "Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (Revision as of February 19, 2007)." The method or combination of methods used in the analysis of each reservoir was tempered by experience with similar reservoirs, stage of development, quality and completeness of basic data, and production history.

> > > > When applicable, the volumetric method was used to estimate the original oil in place (OOIP) and the original gas in place (OGIP). Structure and isopach maps were constructed to estimate reservoir volume. Electrical logs, radioactivity logs, core analyses, and other available data were used to prepare these maps as well as to estimate representative values for porosity and water saturation. When adequate data were available and when circumstances justified, material balance and other engineering methods were used to estimate OOIP or OGIP.

> > > > Estimates of ultimate recovery were obtained after applying recovery factors to OOIP or OGIP. These recovery factors were based on consideration of the type of energy inherent in the reservoirs, analyses of the petroleum, the structural positions of the properties, and the production histories. When applicable, material balance

> > > > For depletion-type reservoirs or those whose performance disclosed a reliable decline in producing-rate trends or other diagnostic characteristics, reserves were estimated by the application of appropriate decline curves or other performance relationships. In the analyses of production-decline curves, reserves were estimated only to the limits of economic production or to the limit of production licenses as appropriate.

> > > > Definition of Reserves

> > > > Petroleum reserves included in this report are classified as proved. Reserves classifications used for our estimates of proved reserves are in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the SEC. Eni has represented that its estimates of proved reserves are in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the SEC. Reserves are judged to be economically producible in future years from known reservoirs under existing economic and operating conditions and assuming continuation of current regulatory practices using known production methods and equipment. In the analyses of production-decline curves, reserves were estimated only to the limit of economic rates of production under existing economic and operating conditions using prices and costs consistent with the effective date of this report, including consideration of changes in existing prices provided only by contractual arrangements but not including escalations based upon future conditions. The petroleum reserves are classified as follows:

> > > > > Proved oil and gas reserves – Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the

Dear Ms. Feudaroli:

At the request of Eni S.p.A. (Eni), Ryder Scott Company (Ryder Scott) has conducted a reserves audit of the estimates of the proved reserves as prepared by Eni’s engineering and geological staff based on the definitions and disclosure guidelines of the United States Securities and Exchange Commission (SEC) contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009 in the Federal Register (SEC regulations). Our third party reserves audit, completed on January 31, 2011 and presented herein, was prepared for public disclosure by Eni in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. Eni has indicated that the proved net reserves attributable to the properties that we reviewed account for 15 percent of their total net proved remaining hydrocarbon reserves. The subject properties are located in the following geographic locations:

> > > > > > • Africa
> > > > > > • Asia
> > > > > > • America

As prescribed by the Society of Petroleum Engineers in Paragraph 2.2(f) of the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards), a reserves audit is defined as "the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of reserves prepared by others and the rendering of an opinion about (1) the appropriateness of the methodologies employed; (2) the adequacy and quality of the data relied upon; (3) the depth and thoroughness of the reserves estimation process; (4) the classification of reserves appropriate to the relevant definitions used; and (5) the reasonableness of the estimated reserve quantities."

Based on our review, including the data, technical processes and interpretations presented by Eni, it is our opinion that the overall procedures and methodologies utilized by Eni in preparing their estimates of the proved reserves as of December 31, 2010 comply with the current SEC regulations and that the overall proved reserves for the reviewed properties as estimated by Eni are, in the aggregate, reasonable within 5 percent of Ryder Scott’s estimates which is less than the established audit tolerance guidelines of 10 percent as set forth in the SPE auditing standards.

The conclusions discussed in this report, as of December 31, 2010, are related to hydrocarbon prices. The hydrocarbon prices used in the preparation of this report are based on the average prices during the 12-month period prior to the ending date of the period covered in this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month

within such period, unless prices were defined by contractual arrangements, as required by the SEC regulations. Actual future prices may vary significantly from the prices required by SEC regulations; therefore, volumes of reserves actually recovered may differ significantly from the estimated quantities audited by Ryder Scott.

Reserves Included in This Report

The proved reserves included herein conform to the definition as set forth in the Securities and Exchange Commission’s Regulations Part 210.4-10(a). An abridged version of the SEC reserves definitions from 210.4-10(a) entitled "Petroleum Reserves Definitions" is included as an attachment to this report. The various proved reserve status categories are defined under the attachment entitled "Petroleum Reserves Definitions" in this report.

No attempt was made to quantify or otherwise account for any accumulated gas production imbalances that may exist. The audited proved gas volumes included gas consumed in operations as reserves. Non-hydrocarbon or inert gas volumes have been excluded from the reserves reported herein.

Reserves are those estimated remaining quantities of petroleum that are anticipated to be economically producible, as of a given date, from known accumulations under defined conditions. All reserve estimates involve an assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves, and may be further sub-classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. At Eni’s request, this report addresses only the proved reserves attributable to the properties evaluated herein.

Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward. The proved reserves included herein were estimated using deterministic methods. If deterministic methods are used, the SEC has defined reasonable certainty for proved reserves as a "high degree of confidence that the quantities will be recovered."

Proved reserve estimates will generally be revised only as additional geologic or engineering data become available or as economic conditions change. For proved reserves, the SEC states that "as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to the estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease." Moreover, estimates of proved reserves may be revised as a result of future operations, effects of regulation by governmental agencies or geopolitical or economic risks. Therefore, the proved reserves included in this report are estimates only and should not be construed as being exact quantities, and if recovered, the revenues therefrom, and the actual costs related thereto, could be more or less than the estimated amounts.

The proved reserves reported herein are limited to the period prior to expiration of current contracts providing the legal rights to produce, or a revenue interest in such production, unless evidence indicates that contract renewal is reasonably certain. Furthermore, properties in the different countries may be subjected to significantly varying contractual fiscal terms that affect the net revenue

to Eni for the production of these volumes. The prices and economic return received for these net volumes can vary significantly based on the terms of these contracts. Therefore, when applicable, Ryder Scott reviewed the fiscal terms of such contracts and discussed with Eni the net economic benefit attributed to such operations for the determination of the net hydrocarbon volumes and income thereof. Ryder Scott has not conducted an exhaustive audit or verification of such contractual information. Neither our review of such contractual information nor our acceptance of Eni’s representations regarding such contractual information should be construed as a legal opinion on this matter.

Ryder Scott did not evaluate the country and geopolitical risks in the countries where Eni operates or has interests. Eni’s operations may be subject to various levels of governmental controls and regulations. These controls and regulations may include, but may not be limited to, matters relating to land tenure and leasing, the legal rights to produce hydrocarbons including the granting, extension or termination of production sharing contracts, the fiscal terms of various production sharing contracts, drilling and production practices, environmental protection, marketing and pricing policies, royalties, various taxes and levies including income tax, and foreign trade and investment and are subject to change from time to time. Such changes in governmental regulations and policies may cause volumes of proved reserves actually recovered and amounts of proved income actually received to differ significantly from the estimated quantities.

The estimates of proved reserves audited herein were based upon a detailed study of the properties in which Eni owns an interest; however, we have not made any field examination of the properties. No consideration was given in this report to potential environmental liabilities that may exist nor were any costs included for potential liabilities to restore and clean up damages, if any, caused by past operating practices.

Audit Data, Methodology, Procedure and Assumptions

The estimation of reserves involves two distinct determinations. The first determination results in the estimation of the quantities of recoverable oil and gas and the second determination results in the estimation of the uncertainty associated with those estimated quantities in accordance with the definitions set forth by the Securities and Exchange Commission’s Regulations Part 210.4-10(a). The process of estimating the quantities of recoverable oil and gas reserves relies on the use of certain generally accepted analytical procedures. These analytical procedures fall into three broad categories or methods: (1) performance-based methods; (2) volumetric-based methods; and (3) analogy. These methods may be used singularly or in combination by the reserve evaluator in the process of estimating the quantities of reserves. Reserve evaluators must select the method or combination of methods which in their professional judgment is most appropriate given the nature and amount of reliable geoscience and engineering data available at the time of the estimate, the established or anticipated performance characteristics of the reservoir being evaluated and the stage of development or producing maturity of the property.

In many cases, the analysis of the available geoscience and engineering data and the subsequent interpretation of this data may indicate a range of possible outcomes in an estimate, irrespective of the method selected by the evaluator. When a range in the quantity of reserves is identified, the evaluator must determine the uncertainty associated with the incremental quantities of the reserves. If the reserve quantities are estimated using the deterministic incremental approach, the uncertainty for each discrete incremental quantity of the reserves is addressed by the reserve category assigned by the evaluator. Therefore, it is the categorization of reserve quantities as proved, probable and/or possible that addresses the inherent uncertainty in the estimated quantities reported. For proved reserves, uncertainty is defined by the SEC as reasonable certainty wherein the "quantities

actually recovered are much more likely than not to be achieved." The SEC states that "probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered." The SEC states that "possible reserves are those additional reserves that are less certain to be recovered than probable reserves and the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable plus possible reserves." All quantities of reserves within the same reserve category must meet the SEC definitions as noted above.

Estimates of reserves quantities and their associated reserve categories may be revised in the future as additional geoscience or engineering data become available. Furthermore, estimates of reserves quantities and their associated reserve categories may also be revised due to other factors such as changes in economic conditions, results of future operations, effects of regulation by governmental agencies or geopolitical or economic risks as previously noted herein.

The proved reserves for the properties included herein were estimated by performance methods, analogy methods, the volumetric method, or a combination of performance and volumetric methods. These performance methods include, but may not be limited to, decline curve analysis and analogy which utilized extrapolations of historical production and pressure data available through December, 2010 in those cases where such data were considered to be definitive. The data utilized in this analysis were supplied to Ryder Scott by Eni and were considered sufficient for the purpose thereof. The volumetric method was used where there were inadequate historical performance data to establish a definitive trend and where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate. The volumetric analysis utilized pertinent well and seismic data supplied to Ryder Scott by Eni that were available through December, 2010. The data utilized from the well and seismic data incorporated into our volumetric analysis were considered sufficient for the purpose thereof.

To estimate economically recoverable proved oil and gas reserves and related future net cash flows, we consider many factors and assumptions including, but not limited to, the use of reservoir parameters derived from geological, geophysical and engineering data that cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices received for the sale of production and the operating costs and other costs relating to such production may increase or decrease from those under existing economic conditions, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in making this evaluation.

Eni has informed us that they have furnished us all of the material accounts, records, geological and engineering data, and reports and other data required for this investigation. In preparing our forecast of future proved production and income, we have relied upon data furnished by Eni with respect to property interests owned, production and well tests from examined wells, normal direct costs of operating the wells or leases, other costs such as transportation and/or processing fees, ad valorem and production taxes, recompletion and development costs, abandonment costs after salvage, product prices based on the SEC regulations, adjustments or differentials to product prices, geological structural and isochore maps, well logs, core analyses, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have not conducted an independent verification of the data furnished by Eni. We consider the factual data used in this report appropriate and sufficient for the purpose of our investigations.

In summary, we consider the assumptions, data, methods and analytical procedures used in this report appropriate for the purpose hereof, and we have used all such methods and procedures that we consider necessary and appropriate to conduct the audit of reserves of the properties described herein. The proved reserves discussed herein were determined in conformance with the United States Securities and Exchange Commission (SEC) Modernization of Oil and Gas Reporting; Final Rule, including all references to Regulation S-X and Regulation S-K, referred to herein collectively as the "SEC Regulations." In our opinion, the proved reserves reviewed in this report comply with the definitions, guidelines and disclosure requirements as required by the SEC regulations.

Future Production Rates

For wells currently on production, our forecasts of future production rates are based on historical performance data. If no production decline trend has been established, future production rates were held constant, or adjusted for the effects of curtailment where appropriate, until a decline in ability to produce was anticipated. An estimated rate of decline was then applied to depletion of the reserves. If a decline trend has been established, this trend was used as the basis for estimating future production rates.

Test data and other related information were used to estimate the anticipated initial production rates for those wells or locations that are not currently producing. For reserves not yet on production, sales were estimated to commence at an anticipated date furnished by Eni. Wells or locations that are not currently producing may start producing earlier or later than anticipated in our estimates due to unforeseen factors causing a change in the timing to initiate production. Such factors may include delays due to weather, the availability of rigs, the sequence of drilling, completing and/or recompleting wells and/or constraints set by regulatory bodies.

The future production rates from wells currently on production or wells or locations that are not currently producing may be more or less than estimated because of changes including, but not limited to, reservoir performance, operating conditions related to surface facilities, compression and artificial lift, pipeline capacity and/or operating conditions, producing market demand and/or allowables or other constraints set by regulatory bodies.

Hydrocarbon Prices

The hydrocarbon prices used herein are based on SEC price parameters using the average prices during the 12-month period prior to the ending date of the period covered in this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements. For hydrocarbon products sold under contract, the contract prices, including fixed and determinable escalations, exclusive of inflation adjustments, were used until expiration of the contract. Upon contract expiration, the prices were adjusted to the 12-month unweighted arithmetic average as previously described.

Eni furnished us with the above mentioned average prices in effect on December 31, 2010. Eni has assured us that these initial SEC hydrocarbon prices were determined using the 12-month average first-day-of-the-month benchmark prices appropriate to the geographic area where the hydrocarbons are sold. The average dated Brent oil price of $79/Bbl was used by Eni. Eni also provided us with the gas prices based on their gas sales agreements. The average realized prices provided by Eni and used in our evaluation are as follows:

The product prices that were actually used to determine the future gross revenue for each property reflect adjustments to the benchmark prices for gravity, quality, local conditions and/or distance from market, referred to herein as "differentials." The differentials used in the preparation of this report were furnished to us by Eni. The differentials furnished to us were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the data used by Eni to determine these differentials.

Costs

Operating costs used in our evaluation were based on the operating expense reports of Eni and include only those costs directly applicable to the evaluated assets. The operating costs include a portion of general and administrative costs allocated directly to the leases and wells. The operating costs furnished to us were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of the operating cost data used by Eni. No deduction was made for loan repayments, interest expenses, or exploration and development prepayments that were not charged directly to the assets.

Development costs were furnished to us by Eni and are based on authorizations for expenditure for the proposed work or actual costs for similar projects. The development costs furnished to us were accepted as factual data and reviewed by us for their reasonableness; however, we have not conducted an independent verification of these costs. The estimated net cost of abandonment after salvage was included for properties where abandonment costs net of salvage were significant. The estimates of the net abandonment costs furnished by Eni were accepted without independent verification.

The proved developed and undeveloped reserves in this report have been incorporated herein in accordance with Eni’s plans to develop these reserves as of December 31, 2010. The implementation of Eni’s development plans as presented to us and incorporated herein is subject to the approval process adopted by Eni’s management. As the result of our inquires during the course of preparing this report, Eni has informed us that the development activities included herein have been subjected to and received the internal approvals required by Eni’s management at the appropriate local, regional and/or corporate level. In addition to the internal approvals as noted, certain development activities may still be subject to specific partner AFE processes, Joint Operating Agreement (JOA) requirements or other administrative approvals external to Eni. Additionally, Eni has informed us that they are not aware of any legal, regulatory, political or economic obstacles that would significantly alter their plans.

Current costs used by Eni were held constant throughout the life of the properties.

PETROLEUM RESERVES DEFINITIONS

As Adapted From:
RULE 4-10(a) of REGULATION S-X PART 210
UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC)

PREAMBLE

On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the "Modernization of Oil and Gas Reporting; Final Rule" in the Federal Register of National Archives and Records Administration (NARA). The "Modernization of Oil and Gas Reporting; Final Rule" includes revisions and additions to the definition section in Rule 4-10 of Regulation S-X, revisions and additions to the oil and gas reporting requirements in Regulation S-K, and amends and codifies Industry Guide 2 in Regulation S-K. The "Modernization of Oil and Gas Reporting; Final Rule", including all references to Regulation S-X and Regulation S-K, shall be referred to herein collectively as the "SEC Regulations". The SEC Regulations take effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January 1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-10(a) for the complete definitions, as the following definitions, descriptions and explanations rely wholly or in part on excerpts from the original document (direct passages excerpted from the aforementioned SEC document are denoted in italics herein).

Reserves are those estimated remaining quantities of petroleum which are anticipated to be economically producible, as of a given date, from known accumulations under defined conditions. All reserve estimates involve some degree of uncertainty. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. Under the SEC Regulations as of December 31, 2009, or after January 1, 2010, a company may optionally disclose estimated quantities of probable or possible oil and gas reserves in documents publicly filed with the Commission. The SEC Regulations continue to prohibit disclosure of estimates of oil and gas resources other than reserves and any estimated values of such resources in any document publicly filed with the Commission unless such information is required to be disclosed in the document by foreign or state law as noted in §229.1202 Instruction to Item 1202.

Reserves estimates will generally be revised as additional geologic or engineering data become available or as economic conditions change.

Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all methods for supplementing natural energy or altering natural forces in the reservoir to increase ultimate recovery. Examples of such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of miscible and immiscible displacement fluids. Other improved recovery methods may be developed in the future as petroleum technology continues to evolve.

PETROLEUM RESERVES DEFINITIONS
Page 2

Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method applied, or degree of processing prior to sale. Examples of unconventional petroleum accumulations include coalbed or coalseam methane (CBM/CSM), basin-centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional accumulations may require specialized extraction technology and/or significant processing prior to sale.

Reserves do not include quantities of petroleum being held in inventory.

Because of the differences in uncertainty, caution should be exercised when aggregating quantities of petroleum from different reserves categories.

RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows:

Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project.

Note to paragraph (a) (26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations).

PROVED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §229.4-10(a) (22) defines proved oil and gas reserves as follows:

Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

> (i) The area of the reservoir considered as proved includes:

> > (A) The area identified by drilling and limited by fluid contacts, if any, and

##### Table of Contents

PETROLEUM RESERVES DEFINITIONS
Page 3

> > (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

> (ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

> PROVED RESERVES (SEC DEFINITIONS) CONTINUED

> (iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

> (iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when:

> > (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based: and

> > (B) The project has been approved for development by all necessary parties and entities, including governmental entities.

> (v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

> > (i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

> > (ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances. justify a longer time.

> > (iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in paragraph (a) (2) of this section. or by other evidence using reliable technology establishing reasonable certainty.
