ENI OPERATING AND FINANCIAL REVIEW / HIGHLIGHTS

Highlights

Financial highlights
› In the first half of 2010 Eni reported net profit of euro 4.05 billion, up 47.9% from a year earlier. On an adjusted basis, net profit amounted to euro 3.45 billion, up 29.5%, reflecting an excellent operating performance reported by the Exploration & Production division driven by higher oil realizations.

› Net cash provided by operating activities amounted to euro 9.14 billion and proceeds from divestments were euro 795 million. Those inflows were used to fund capital expenditures of euro 7.1 billion to support continued growth in the business and exploration projects and the payment of dividend to Eni’s shareholders and to minorities (euro 2.16 billion), resulting in a small increase in net borrowings from December 31, 2009.

› As of June 30, 2010, the ratio of net borrowings to total equity – leverage – decreased to 0.41 from 0.46 as of December 31, 2009, benefiting from a sizeable increase in shareholders’ equity associated with the appreciation of the US dollar (up 15%).

› Capital expenditures amounted to euro 7,107 million and mainly regarded continuing development of oil and gas reserves, exploration activities with 97% of expenditure located outside Italy, the upgrading of rigs and offshore vessels in the Engineering & Construction segment and of the gas transport and storage infrastructure.

› Based on the fist half of 2010 results and taking into account the projected full-year results and outlook, the interim dividend proposal to Eni’s Board of Directors will amount to euro 0.50 per share (euro 0.50 in 2009). The interim dividend is payable from September 23, 2010, being the ex-dividend date September 20, 2010.

Operational highlights
› Eni reported liquids and gas production of 1,800 kboe/d for the first half of 2010, which included the effect of updating the gas conversion rate (currently 5,550 cubic feet of gas equals 1 barrel of oil, it was 5,742 cubic feet of gas per barrel until April 1, 2010). When excluding this effect, production grew by 1% from the first half of 2009 as a result of continuing production ramp-up in Nigeria, Congo and USA and additions from new field start-ups and production ramp-ups.

› In line with production plans, a total of 5 fields were started up of the 12 fields scheduled for 2010. The main start-ups were Annamaria B (Eni operator with a 90% interest) located between Italy and Croatia, Baraka (Eni operator with a 49% interest) in Tunisia, Rom Integrated in Algeria and M’Boundi IPP (Eni’s interest 100%) in Congo, in addition to minor projects in China and Nigeria.

› In the first half of 2010 exploration reserves of 600 million barrels have been added to the Company’s resource base. The main successes were achieved in Venezuela with the Perla 2 appraisal well (Eni operator with a 50% interest), in Angola with three new oil discoveries in the rich offshore Block 15/06 (Eni operator with a 35% interest) and in Indonesia with success in the Muara Bakau permit (Eni operator with a 55% interest).

› Eni’s worldwide natural gas sales were 49.7 bcm, down 5.9% from a year earlier. Performance was negatively affected by sharply lower volumes supplied to the Italian market (down 19%) due to increased competitive pressures in the power generation business, as well as in sales to industrial customers and wholesalers. This decrease was partly offset by organic growth achieved in European markets (up 4.9%) in particular in France, Belgium and Germany/Austria.

ENI OPERATING AND FINANCIAL REVIEW / HIGHLIGHTS

Portfolio developments
Russia
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.

As part of the transaction to divest a 51% stake in the joint-venture Eni-Enel OOO SeverEnergia to Gazprom, based on the call option exercised by the Russian company on September 24, 2009, Eni collected a second installment of the transaction by March 31, 2010. This amounted to euro 526 million (approximately 75% of the whole amount of the transaction).

Divestment of a 25% share capital interest in GreenStream BV
On April 27, 2010, Eni sold a 25% stake in the share capital of GreenStream BV to NOC (Libyan National Oil Corporation), the company owning and managing the gas pipeline for importing to Italy natural gas produced in Libya. Following the decrease of Eni’s shareholding in the company to 50% and implementation of renewed shareholders arrangements, Eni no longer controls the company and it has therefore been excluded from consolidation as of May 1, 2010.

Brazil
On May 27, 2010, Eni signed a preliminary agreement to divest its 100% interest in Gas Brasiliano Distribuidora, a company that markets and distributes natural gas in Brazil, to Petrobras Gàs, a fully owned subsidiary of Petróleo Brasileiro ("Petrobras"). Total cash consideration is expected to amount to approximately $250 million. The completion of the transaction is subject to approval of the relevant Brazilian authorities.

Disclaimer
This report contains certain forward-looking statements in particular under the section "Outlook" regarding capital expenditures, development and management of oil and gas resources, dividends, allocation of future cash flow from operations, future operating performance, gearing, targets of production and sale growth, new markets, and the progress and timing of projects. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that will or may occur in the future. Actual results may differ from those expressed in such statements, depending on a variety of factors, including the timing of bringing new fields on stream; management’s ability in carrying out industrial plans and in succeeding in commercial transactions; future levels of industry product supply; demand and pricing; operational problems; general economic conditions; political stability and economic growth in relevant areas of the world; changes in laws and governmental regulations; development and use of new technology; changes in public expectations and other changes in business conditions; the actions of competitors and other factors discussed elsewhere in this document.

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

ENI INTERIM CONSOLIDATED REPORT / OPERATING REVIEW

Oil and gas production

In the first half of 2010, Eni’s reported liquids and gas production was 1,800 kboe/d which was calculated assuming a conversion rate of gas to barrel equivalent which was updated to 5,550 cubic feet of gas equals 1 barrel of oil. On a comparable basis, i.e. when excluding the effect of updating the gas conversion rate, production grew by 1%. Production increases were driven by organic growth achieved in Nigeria, Congo and the United States, new field start-ups and |  | production ramp-ups at fields which were started-up in 2009. Those trends were offset by planned facility shutdowns in the North Sea and in Kazakhstan, as well as mature field declines. Also, performance was affected by the combined negative impact associated with lower entitlements in Company’s PSAs due to higher oil prices net of lower OPEC restrictions (overall down 15 kboe/d). The share of oil and natural gas produced outside Italy was 90% (90% in the first half of 2009).

ENI INTERIM CONSOLIDATED REPORT / OPERATING REVIEW

Liquid production (995 kbbl/d) declined by 5 kbbl/d from the first half of 2009 (down 0.5%). The main reductions reflected mature field declines, planned facility shutdowns in the North Sea and Kazakhstan as well as the combined negative impact associated with lower entitlements in Company’s PSAs due to higher oil prices net of lower OPEC restrictions. These negatives were partly offset by organic growth achieved in Nigeria, due to the ramp-up of the Oyo project (Eni’s interest 40%) and lower impact of disruptions resulting from security issues, Congo, due to the ramp-up of the Awa Paloukou project (Eni’s interest 90%) and the United States, due to the contribution of the Thunderhawk (Eni’s interest 25%), Leo (Eni’s interest 75%) and Longhorn (Eni’s interest 75%) projects. Natural gas production (4,466 mmcf/d) increased by 122 mmcf/d from the first half of 2009 (up 2.4%). The main increases were registered in Nigeria and the USA due to organic growth as well as in Congo due to the start-up of the M’Boundi IPP project (Eni’s interest 100%). Main decreases were registered in the North Sea and Egypt due to the planned facility shutdowns and mature field declines. Oil and gas production sold net of updating the natural gas conversion rate amounted to 308.3 mmboe. On a comparable basis, the difference over production (320.9 mmboe) reflected volumes of natural gas consumed in operations (9.8 mmboe). Main exploration and development projects ITALY In March 2010, production started-up at the Annamaria B production platform (Eni operator with a 90% interest), located at the border with Croatian territorial waters. Full production is targeted at approximately 42 mmcf/d in the third quarter of 2010. Development projects progressed at the Bonaccia East, Guendalina, Capparuccia and Tresauro fields. Other activities were aimed at upgrading facilities and maintaining production levels by means of sidetracking and work over activities at the Barbara, Annalisa, Azalea and Gela fields as well as in the Val d’Agri concession (Eni’s interest 60.77%) where rigless activities were completed.

NATURAL GAS
Supply of natural gas

In the first half of 2010, Eni’s consolidated subsidiaries supplied 41.65 bcm of natural gas, including 8.84 bcm supplied by Distrigas. This represented a decrease of 2.42 bcm, or 5.5% from the first half of 2009, reflecting a decline in natural gas sales. Gas volumes supplied outside Italy (38.03 bcm from consolidated companies), imported in Italy or sold outside Italy, represented 90% of total supplies, a decrease of 2.56 bcm, or 6.3%, from the first half of 2009, mainly due to lower volumes purchased from Russia, where Eni reduced its off-takes in particular volumes directed to Italy (down 3.43 bcm). In the first half of 2010 higher volumes were purchased |  | from the Netherlands (up 1.23 bcm) and Norway (up 0.62 bcm). Supplies in Italy (3.62 bcm) increased by 0.14 bcm from the first half of 2009, or 4%. In the first half of 2010, main gas volumes from equity production derived from: (ii) Italian gas fields (3.3 bcm); (ii) the Wafa and Bahr Essalam fields in Libya linked to Italy through the GreenStream pipeline. In the first half of 2010 these two fields supplied 1.3 bcm net to Eni; (iii) certain Eni fields located in the British and Norwegian sections of the North Sea (1.4 bcm); and (iv) other European areas (in particular Croatia with 0.3 bcm).

Sales of natural gas

In the first half of 2010, worldwide natural gas sales of 49.70 bcm, including own consumption, sales by affiliates and E&P sales in Europe and in the Gulf of Mexico, declined from the first half of 2009 (down 3.11 bcm, or 5.9%) mainly due to the significant decline in gas sales in Italy and increasing competitive pressures in the power generation, industrial and wholesalers segment. These decreases were partially offset by steady trends in sales on the European markets. Natural gas sales in Italy were 17.14 bcm (including own consumption and sales by affiliates), a decline of 3.97 bcm from 2009, or 18.8%, due to strong competitive pressures and to oversupply conditions characterizing the marketplace. Eni suffered lower sales in almost all of its segments, including the power generation business (down 3.42 bcm) and, at a lower extent, wholesalers (down 1.17 bcm) and industrial customers (down 1 bcm). Sales volumes to the residential sector (3.87 |  | bcm) were nearly unchanged, while sales to medium-sized enterprises and services posted a small increase (up 0.06 bcm). International sales were up 0.86 bcm, or 2.7%, to 32.56 bcm, benefiting from organic growth achieved on target markets in the Rest of Europe, particularly in France (up 0.65 bcm), Belgium (up 0.60 bcm), Germany/Austria (up 0.39 bcm) and in Northern Europe (up 0.31 bcm). Sales decreases were recorded in Turkey (down 0.87 bcm), Hungary (down 0.11 bcm) and to importers in Italy (down 0.42 bcm). Sales to markets outside Europe (1.14 bcm) increased by 0.22 bcm from the first half of 2009. E&P sales in Europe and the Gulf of Mexico (2.94 bcm) were stable.

In the first half of 2010, the LNG terminal in Panigaglia (La Spezia) regasified 1.11 bcm of natural gas (up 0.47 bcm, or 73.4%, from the first half of 2009). |  | Storage In the first half of 2010, 4.84 bcm of gas were offtaken (down 1.21 bcm from the first half of 2009) while 3.81 bcm were input to Company’s storage deposits, a decrease of 0.49 bcm compared to the same period of 2009. Storage capacity amounted to 14.2 bcm, of which 5 bcm were destined to strategic storage. The share of modulation storage capacity used by third parties was about 76% (64% in the first half of 2009).

ENI INTERIM CONSOLIDATED REPORT / OPERATING REVIEW

Main development projects for the first half of 2010 Marketing Divestment of Gas Brasiliano Distribuidora SA On May 27, 2010 Eni signed a preliminary agreement to divest its 100% interest in Gas Brasiliano Distribuidora, a company that markets and distributes natural gas in Brazil, to Petrobras Gàs, a fully owned subsidiary of Petróleo Brasileiro ("Petrobras"). Total cash consideration is expected to amount to $250 million. The completion of the transaction is subject to approval of the relevant Brazilian authorities. International transport Sale of 25% of the share capital of GreenStream BV On April 27, 2010, Eni sold to NOC (Libyan National Oil Corporation) a 25% stake in the share capital of GreenStream BV, the company owning and managing the gas pipeline for importing to Italy natural gas produced in Libya. Following the decrease of Eni’s shareholding in the company to 50% and the implementation of renewed shareholders arrangements, Eni no longer controls the company and it has therefore been excluded from the consolidation area as of May 1, 2010. GreenStream BV operates the import gas pipeline from Libya which in 2009 transported approximately 9 bcm. The company is part of the Western Libyan Gas Project which includes a 520-kilometer long gas underwater pipeline with a diameter of 32 inches, a compression station in Mellitah and a terminal in Gela in Sicily, the point of entry into the Italian natural gas transport system managed by Snam Rete Gas. In 2009 the pipeline was upgraded by 3 bcm/y, which are expected to come fully on stream in 2010, bringing total capacity to 11 bcm/y. South Stream 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. |  | Regulatory framework Framework legislative decree 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 23 July, 2009, No. 99 Implementing the provisions of Law 99/2009, on April 23, 2010, the Italian Council of Ministers approved a framework decree for introducing a system of wholesale market shares for operators inputting natural gas in the Italian transport network which substitutes the existing antitrust ceilings introduced by Legislative Decree No. 164/2000 due to expire at the end of 2010, also identifying new measures for increasing competition in the natural gas market. This draft decree has been examined and approved by the relevant parliamentary commissions, under certain conditions, and is awaiting finalization. The decree provides that antitrust ceilings be calculated with reference to the market share of each operator and no longer to the amount of natural gas input by that subject into the national network. Market shares are going to be calculated starting from this input amount which will be increased with the purchases and sales of each operator under a method to be defined. Said market share will be not 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 is provided in case an operator fails to comply with the mandatory ceilings on the market share. The incumbent operator will be allowed to increase its threshold to 60% if it commits itself to developing new storage capacity of 4 billion cubic meters. In this case, this operator will: (i) allow third parties (such as industrial customers, groups of companies, consortia of final customers) to participate in the construction of storage infrastructure either by means of direct investment or of long term contracts for storage services; (ii) respect the mechanism of advancement of benefits under conditions and volumes defined by the Ministry of Economic Development and the Authority for Electricity and Gas (AEEG). The decree also introduces measures aiming at regulating the upgrading of strategic infrastructure such as regasification terminals and gas pipelines, at increasing storage capacity, supporting the security of supplies and increasing flexibility in the gas system, in addition to transferring the benefits deriving from a more open market to end users.

Eni’s management is monitoring this area and evaluating any possible financial or economic impact associated with the proposed measures. Resolution ARG/gas 89/10 - Change in the criteria for determining and upgrading tariffs applied to residential customers Following a consultation procedure initiated by the Authority for Electricity and Gas with DCO 5/10 consultation document regarding the mechanism used to determine and update the tariffs for supplying residential users with consumption lower than 200 thousands of cubic meters, on June 18, 2010, the Authority published a resolution, ARG/gas 89/10, 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 reflecting the current scenario of the Italian gas market in terms of supply, the impact of the economic downturn and the potential outcomes of the renegotiation of long-term supply contracts on part of Italian importers. Considering the new calculation does not cover 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 is considering an appeal against the ARG/gas 89/10 resolution. Negotiation Platform for gas trading 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). This trading platform will evolve into a more structured gas exchange, effective from October 1, 2010. Currently on this platform, certain volumes of gas are traded that correspond 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 to the virtual exchange in order to receive permission to import. Eni is required to offer at |  | that platform about 40 mmcm, completing the offer obligation related to the volumes imported in thermal year October 1, 2008-September 30, 2009 that had been submitted to the virtual exchange in 2009, as well as approximately 150/160 mmcm related to the October 1, 2009-September 30, 2010 thermal 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 Authority for Electricity and Gas. With a later administrative measure, also royalties due to the Italian state by gas producers will be traded on the virtual exchange. European Directive No. 2009/73/CE of the European Parliament and Council on common regulations for the internal natural gas market On July 13, 2009 European Directive No. 2009/73/CE 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; - 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. While respecting the functional unbundling rules in force, as per AAEG Resolution No. 11/2007 as amended, Eni is monitoring the evolution of European rules and the possible economic and financial impacts associated with this matter.

approximately 80 ktonnes, or up 3.2%, in particular due to higher volumes processed in the Czech Republic in response to the recovery of market demand. Total throughputs at wholly-owned refineries (12.40 mmtonnes) increased by approximately 780 ktonnes, up 6.7%, from the first half of 2009, resulting in a 90% utilization rate as a consequence of the end of some processing contracts on account of third parties.

Retail sales in Italy In the first half of 2010, retail sales in Italy (4.18 mmtonnes) slightly decreased from the first half of 2009 (down by approximately 230 ktonnes, or 5.2%). These reductions were mainly due to lower domestic demand for fuels, in particular for gasoline. Eni’s retail market share for the first half of 2010 was 30.3% down 1.3 percentage points from the corresponding period of 2009 (31.6%). As of June 30, 2010, Eni’s retail network in the rest of Europe consisted of 4,503 units, an increase of 29 units from December 31, 2009 (4,474 service stations), resulting from the positive balance of acquisitions/releases of lease concessions (37 units), the opening of new service stations (5 units), which were partially offset by the closing of low throughput service stations (10 units) and the release of 3 service stations under highway concession. Average throughput related to gasoline and gasoil (1,130 kliters) registered a decrease of approximately 86 kliters from the first half of 2009. In the first half of 2010, sales of BluDieselTech amounted to approximately 281 ktonnes (approximately 337 mmliters), registering a slight decline from the first half of |  | 2009, and represented 10.4% of gasoil sales on Eni’s retail network. As of June 30, 2010, service stations marketing BluDieselTech totaled 4,115 units (4,104 as of December 31, 2009) covering approximately 91% of Eni’s network. Retail sales of BluSuper amounted to approximately 34 ktonnes (approximately 45 mmliters), registering a slight decrease from the first half of 2009, and covered 2.5% of gasoline sales on Eni’s retail network. As of June 30, 2010, service stations marketing BluSuper totaled 2,699 units (2,679 as of December 31, 2009), covering approximately 60% of Eni’s network. In February 2010, to substitute the promotional campaign "You&Agip" completed in 2009, Eni launched the new fidelity program "you&eni" which will last for 3 years until January 31, 2013. As of June 30, 2010, the number of cards used by customers in the period amounted to approximately 3.9 million. The average number of cards active each month was approximately 2.7 million. Volumes of fuel marketed under this initiative represented over 42% of total volumes marketed on Eni’s service stations joining the program, and approximately 41% of overall volumes marketed on Eni’s network.

Retail sales in the Rest of Europe In the first half of 2010, retail sales of refined products marketed in the rest of Europe (1.44 mmtonnes) were almost in line with the same period of 2009. Increases were recorded in Slovakia, France and Romania, while decreases were recorded mainly in Germany and Hungary. At June 30, 2010, Eni’s retail network in the rest of Europe consisted of 1,514 units, an increase of 2 units from December 31, 2009 (1,512 service stations). The network evolution was as follows: (i) positive balance of acquisitions/releases of lease concessions (5 units) with positive changes mainly in Hungary; (ii) purchased 4 service stations; (iii) 7 low throughput service stations were closed. Average throughput (1,175 kliters) was nearly unchanged the first half of 2009 (1,177 kliters). |  | Wholesale and other sales In the first half of 2010, sales volumes on wholesale markets in Italy (4.37 mmtonnes) were down 290 ktonnes from the first half of 2009, or 6.2%, mainly reflecting a decrease in demand in particular for fuel oil, due to lower industrial consumption reflecting the economic downturn. Sales on wholesale markets in the rest of Europe (1.83 mmtonnes) increased by approximately 70 ktonnes, or 4%, mainly in France, Germany and the Czech Republic. Supplies of feedstock to the petrochemical industry (approximately 880 ktonnes) increased by approximately 250 ktonnes due to the recovery in industrial demand. Other sales (9.74 mmtonnes) increased by approximately 730 ktonnes, or 8.1%, mainly due to the increase of volumes sold to the cargo market.

Sales-production-prices In the first half of 2010 sales of petrochemical products (3,174 ktonnes) increased by 1,269 ktonnes (or 66.6%) from the first half of 2009 due to a steep increase in average unit prices (50%) and a significant increase in sales volumes (up 17%, particularly in polymers) as a result of the demand recovery from the very low levels of the same period of last year. Petrochemical production (3,748 ktonnes) increased by 494 ktonnes from the first half of 2009, or 15.2% in all business areas. The recovery in demand determined a production increase in all Eni’s main plants, in Italy and outside Italy. Nominal production capacity was substantially in line |  | with the first half of 2009. The average plant utilization rate, calculated on nominal capacity increased from 66% to 76% as a result of higher volumes produced. In particular the volumes produced in the Priolo, Porto Marghera and Dunkerque crackers increased by 80%. Average unit sale prices increased by 50% from the depressed levels registered in 2009. The most relevant increase was registered in the average price of monomers (76% on average) due to the positive impact of the oil price scenario (virgin naphtha prices increased due to an increase in demand while supply was low). Average unit prices of styrene and polyethylene increased by 40%, while elastomers achieved lower increases.

Business trends Basic petrochemicals Basic petrochemical revenues (euro 1,483 million) increased by euro 667 million (up 81.7%) from the first half of 2009 in all the main business segments due to the steep increase in average unit prices (ranging from 50% to 76%) as a result of the improved scenario. In particular sales volumes of olefins and intermediates increased by 20%. Sales volumes of aromatics (up 4%) affected by lower sales volumes of xylems, registered lower increases. Basic petrochemical production (2,536 ktonnes) increased by 361 ktonnes from the first six months of 2009 (up 16.6%) due to the recovery in the demand for monomers. Polymers Polymers revenues (euro 1,596 million) increased by euro 601 million from the first half of 2009 (up 60.4%) due to average unit prices increasing by 44% for styrenic |  | polymers, by 41% for polyethylene following the monomer increases and lower increases for elastomers, up 26%. Sales volumes increased on average by 16.4%. Polymers production (1,212 ktonnes) increased by 133 ktonnes from the first half of 2009 (up 12.3%) as a result of the recovery of production started in the first months of 2010 due to the partial recovery in the main end-markets (automotive, construction and packaging). Production volumes of elastomers, polyethylene and styrene registered an increase from the first half of 2009 (up 15%, 13% and 9%, respectively). Capital expenditures In the first half of 2010 capital expenditures amounted to euro 71 million (euro 45 million in the first half of 2009) and regarded mainly plant upgrades (euro 40 million), energy recovery (euro 10 million), environmental protection, safety and environmental regulation compliance (euro 10 million), and upkeeping (euro 6 million).

The result was driven by an improved operating performance (up by euro 2,780 million, or 43.6% in the first half of 2010) which was mainly reported by the Exploration & Production division. Also higher profits were reported form equity-accounted entities, |  | helped by gains on divestments. These additions were partly offset by higher losses on fair-valued derivative instruments on currencies, which were recognized through profit and loss as they did not meet the formal criteria to be assessed as hedges under IFRS. Finally, Group results were affected by increased income taxes, with a tax rate increasing from 51.6% to 52.7%.

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Adjusted net profit attributable to Eni’s shareholders for the first half of 2010 was euro 3,447 million, an increase of euro 786 million from the first half of 2009 (up 29.5%). Adjusted net profit is calculated by excluding an inventory holding profit of euro 530 million and net special gains of euro 69 million, resulting in an overall adjustment equal to a decrease of euro 599 million. Special charges of operating profit mainly related to light impairment charges of oil&gas properties in the Exploration & Production division and capital expenditures for the period on health, safety and environmental upgrades on assets impaired in previous reporting periods in the Refining & Marketing and Petrochemical divisions. Also provisions for redundancy |  | incentives and environmental provisions were recorded. Those special charges were offset by gains from the divestment of certain non-strategic assets in the Exploration & Production division. Special charges of net profit included a currency adjustment amounting to euro 47 million to the loss provision accrued in the 2009 financial statements to take account of the TSKJ proceeding. Certain special gains were also recorded related to the divestment of a 25% stake in GreenStream BV (euro 93 million), including a gain from revaluating the residual interest in the venture, and a 100% interest in the Belgian company DistriRe SA (euro 47 million), as well as impairment of the Company’s interest in an industrial venture in Venezuela (euro 20 million)1.

(a) |  | This item concerned mainly intragroup sales of commodities, services and capital goods recorded in the assets of the purchasing business segment as of end of the period.

The increase in the Group adjusted net profit in the first half of 2010 reflected higher adjusted net profit mainly reported by: |  |  |  | impacted by high supply costs of oil-based feedstock that were not fully recovered in sales prices.
- |  | The Exploration & Production division reported better adjusted net results (up euro 768 million, or 40.1%) driven by a better operating performance (up euro 2,323 million, or 54.8%). The main positive trends were higher oil realizations in dollar terms. On the negative side, the adjusted tax rate was up by 3.3 percentage points in the first half of 2010 (from 56.8% to 60.1%). |  | - |  | The Engineering & Construction division reported improved net profit (up euro 21 million, or 4.7%) driven by better operating performance (up euro 63 million) due to increased revenues and higher profitability of acquired orders.
These positive performances were partly offset by lower results reported by:
- |  | The Petrochemicals division achieved a remarkable improvement by trimming net loss by euro 143 million or 68.4% (from euro 209 million to euro 66 million). The improvement was driven by a better operating performance (up euro 187 million in the first half of 2010) due to an increase in sales volumes and cost efficiencies. Profitability continued being negatively |  | - |  | The Refining & Marketing division continued to report losses which amounted to euro 49 million for the first half of 2010, compared with net loss of euro 31 million a year ago. The euro 18 million decline (down 58.1%) was mainly due to a further deterioration in operating profitability (down by euro 95 million to euro 146 million), mainly as a result of unprofitable refining

|  | margins, partly offset by higher profits of entities accounted for with the equity method. |  | in Brent prices which were up 49.7% from the first half of 2009. Gas realizations showed a less lively pace (down by 4.8%) due to time lags in oil-linked pricing formulae and weak demand in areas where gas is sold on a spot basis. Underlying fundamentals in the refining business remained weak as high costs of oil-based feedstock were only partially transferred to product prices pressured by excess capacity, sluggish demand and high inventory levels. Eni’s refining margins showed an improvement in the second quarter of 2010, driven by a re-opening of light-heavy crude differentials in the Mediterranean area. This trend benefited the profitability of Eni’s complex refineries, characterized by high conversion rate. The depreciation of the euro vs. the US dollar (down 0.3%) generated a negligible impact on the results of the first half. On the contrary, shareholders’ equity benefited from a large drop recorded in the euro versus the US dollar exchange rate as of end of the first half 2010 which was down by 15% from December 31, 2009 as a result of currency translation differences. This determined a recovery in the net borrowings to shareholders equity ratio – leverage – that decreased to 0.41 at June 30, 2010 from 0.46 as of December 31, 2009.
- |  | The Gas & Power division reported modest changes in adjusted net profit which was euro 9 million lower in the first half of 2010 (down 0.6%) from the previous year. The Marketing performance was sharply lower (down euro 322 million, or 32.6%) pressured by negative pricing conditions in oil-linked formulae, volumes losses in Italy and lowered marketing margins. Those negatives were counterbalanced by the effect of the renegotiation of certain long-term supply contracts and supply optimization actions, as well as a robust performance delivered by the Regulated businesses in Italy (up 18% in the first half), as well as higher profit reported by equity-accounted entities.
Return on average capital employed (ROACE) calculated on an adjusted basis for the twelve-month period to June 30, 2010 was 9.7% (13% at June 30, 2009). Eni’s results for the first half of 2010 were achieved in a trading environment characterized by an average 48.3% increase in hydrocarbon realizations driven by a recovery

Eni’s net sales from operations (revenues) for the first half of 2010 (euro 47,706 million) were up euro 5,698 million from the same period of the previous year (up 13.6%) primarily reflecting higher realizations on oil, products and natural gas in dollar terms. Revenues generated by the Exploration & Production division (euro 14,569 million) increased by euro 2,741 million (up 23.2%) due to higher oil realizations in dollar terms (up |  | 48.3%) reflecting the first half of 2010 trading environment, partly offset by lower gas realizations in dollar (down 4.8%) due to unfavorable time lags in oil-linked pricing formulae and weak spot prices. Eni’s average liquid realizations decreased by 1.22 $/bbl in the first half of 2010 to 71.63 $/bbl, due to the settlement of certain commodity derivatives relating to the sale of 14.2 mmbbl in the first half.

Revenues generated by the Gas & Power division (euro 14,668 million) decreased by euro 2,800 million (down 16%) due in particular to lower volumes sold in Italy (down 4 bcm, or 18.9%) due to higher competitive pressure, partly offset by the positive results reported by subsidiaries operating outside Italy, reflecting organic growth in the international markets. Revenues generated by Refining & Marketing division (euro 20,255 million) increased by euro 6,134 million (up 43.4%) due to higher sales prices. |  | Revenues generated by the Petrochemical division (euro 3,174 million) increased by euro 1,269 million (up 66.6%) from the first half of 2009 mainly reflecting higher sales prices (up 50% on average) and increased sales volumes (up 17%, mainly regarding polymers) due to a recovery of higher end-market demand compared to the particularly depressed market of 2009. Revenues generated by the Engineering & Construction business (euro 5,008 million) increased by euro 127 million (up 2.6%) from the first half of 2009, as a result of the higher levels of activity in the Onshore and Drilling sectors.

Purchases, services and other (euro 32,466 million) increased by euro 2,946 million (up 10%) due to the recovery of supply costs of oil and petrochemicals feedstock affected by energy parameters. Purchases, services and other include euro 97 million of special charges, relating mainly to environmental and other risk provisions. In the first half of 2009, special charges amounting to euro 110 million related mainly to impairment losses on |  | certain receivables associated with a capital project, and environmental and other risk provisions. Payroll and related costs (euro 2,199 million) increased by euro 122 million (up 5.9%) due to higher unit labor cost in Italy and outside Italy (partly reflecting the impact of the appreciation of the dollar), an increase in the average number of employees outside Italy, mainly in the Engineering & Construction business due to higher activity levels, as well as higher provisions for redundancy incentives. These increases were partly offset by a decrease in the average number of employees in Italy.

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Depreciation, depletion and amortization charges (euro 4,370 million) increased by euro 136 million, up 3.2%, mainly in: (i) the Exploration & Production division (up euro 167 million) as new fields were brought into production and increase capital expenditure was incurred in connection with production optimization, partly offset by lower exploration expenditures; (ii) the Engineering & Construction division (up euro 20 million) due to entry into operation of new vessels. A reduction was recorded in the Refining & Marketing division related mainly to a revision of the residual useful lives of refineries and related facilities from January 1, 2010, based also on practices prevailing among European integrated oil companies. In the Gas & Power division, |  | the impact of new assets entered into operation was offset by a revision in the useful life of pipelines (from 40 to 50 years), which was revised recently by the Authority for Electricity and Gas for tariff purposes, starting from January 1, 2010. Impairment charges of euro 89 million mainly regarded impairment charges recorded on oil&gas properties in the Exploration & Production division due to updated commodity prices and cost increases mainly recorded in the Gulf of Mexico and Egypt, as well as capital expenditures for the period on health, safety and environmental upgrades on assets impaired in previous reporting periods in the Refining & Marketing and Petrochemical division.

In the first half o f 2010 Eni’s adjusted operating profit amounted to euro 8,459 million, an increase of euro 2,156 million from the first half of 2009 (up 34.2%). Adjusted operating profit is calculated by excluding an inventory holding profit of euro 777 million and special gains of euro 84 million net, resulting in an overall adjustment equal to a decrease of euro 693 million. |  | - |  | Engineering & Construction (up euro 63 million, or 11.1%) driven by a growth in revenues and higher profitability of acquired orders.
These increases were partly offset by a decrease in the adjusted operating profit reported in the following divisions:
This increase is mainly due to the better operating performance recorded by the following divisions: |  | - |  | Gas & Power (down euro 157 million, or 7.6%) reported a decrease in operating profit affected by the lower operating performance of the Marketing business (down 32.6%), negatively affected by negative pricing conditions in oil-linked formulae, volume losses in Italy and lowered marketing margins, partly offset by the effect of the renegotiation of certain long-term supply contracts and supply optimization actions. The Regulated businesses in Italy delivered a robust performance (up 18%);
- |  | Exploration & Production (up euro 2,323 million, or 54.8%) mainly driven by higher oil realizations in dollars (up 48.3%) and lower exploration expenditure. These positives were partly offset by higher operating expenses and amortization charges, and by lower gas realizations in dollar terms (down 4.8%); |  |  |
- |  | Petrochemicals (up euro 187 million, or 72.8%) driven by a significant increase in sales volumes (up 17%, particularly in polymers) and cost efficiencies. These positives were partly offset by higher supply costs of oil-based feedstock that were not fully recovered in sales prices; |  | - |  | Refining & Marketing (down euro 95 million) reported an operating loss, moving from minus euro 51 million to minus euro 146 million, due to sharply lower refining margins affected by an unfavorable trading environment, mainly in the first quarter of 2010. Also marketing activities in Italy reported a decrease in results, due to lower sales of gasoline.

In the first half of 2010, net finance expense increased by euro 382 million to euro 601 million from the first half of 2009. This increase was mainly related to losses on fair-valued derivative instruments on exchange rates which are recognized through profit and loss as they did not meet the formal criteria to be designated as hedges under IFRS (from a gain of euro 48 million in the first half 2009 to a loss of euro 331 million in the first half of 2010), which effects were partly absorbed by positive exchange differences of euro 243 million. Exchange differences included a euro 47 million adjustment on the |  | loss provision accrued in the 2009 financial statements relating to the TSKJ dispute, to account for the depreciation of the euro over the dollar. Furthermore, in the fist half of 2009 financial gains amounting to euro 172 million had been recorded related to the contractual remuneration on the 20% interest in OAO Gazprom Neft, calculated until April 24, 2009, when Gazprom paid for the call option exercised. Lower finance charges on finance debt reflected lower interest rates on both euro-denominated (down 1.1 percentage points) and dollar loans (down 0.7 percentage points).

Net income from investments
The table below sets forth the breakdown of net income from investments by division for the first half of 2010:

Net income from investments amounted to euro 672 million and related mainly to: (i) Eni’s share of profit of entities accounted for with the equity method (euro 292 million), mainly in the Gas & Power and Exploration & Production divisions; (ii) dividends received by entities accounted for at cost (euro 242 million), mainly relating to Nigeria LNG Ltd; (iii) net gains from divestments (euro 143 million), mainly related to the divestment of a 25% stake in GreenStream (euro 93 million), including a gain |  | from revaluating the residual interest in the venture, and a 100% interest in the Belgian company DistriRe (euro 47 million). These positives were partly offset by impairment of the Company’s interest in an industrial venture in Venezuela (euro 23 million) in the Refining & Marketing division, reflecting net loss for the period and management’s forecast for reduced industrial margins and expectations of further depreciation of the bolivar exchange rate in the future.

Income taxes were euro 4,865 million, up euro 1,504 million, or 44.7%, mainly reflecting an increased taxable profit. In particular, higher income taxes were recorded by subsidiaries in the Exploration & Production division operating outside Italy. Reported tax rate increased by 1.1 percentage points, due to a higher share of profit earned by subsidiaries in the Exploration & Production division which bear a higher tax rate than the Group average tax rate. |  | Adjusted tax rate, calculated as the ratio of income taxes to net profit before taxes on an adjusted basis, was 55.4% (52.1% in the first half of 2009). Non-controlling interest Non-controlling interest’s share of profit was euro 312 million and related mainly to Snam Rete Gas SpA (euro 246 million) and Saipem SpA (euro 46 million).

(a) |  | Excluding special items.

In the first half of 2010 the Exploration & Production division reported an adjusted operating profit of euro 6,560 million, an increase of euro 2,323 million from the first half of 2009, up 54.8%, mainly driven by higher oil realizations in dollars (up 48.3%). Lower expenses were also incurred in connection with exploration activities. These positives were partly offset by rising operating costs and amortization charges taken in connection with development activities as new fields were brought into production, as well as lower gas realizations in dollar (down 4.8%). Special charges excluded from the adjusted operating profit amounted to euro 138 million and mainly concerned gains from the divestment of certain exploration and production assets and light impairments of oil&gas properties. In the first half of 2010 liquid realizations increased |  | on average by 48.3% in dollar terms from the corresponding period a year ago driven by a favorable scenario (Brent increased by 49.7% in the first half of 2010). Eni’s average liquid realizations decreased by 1.22 $/bbl in the first half of 2010 due to the settlement of certain cash flow hedges commodity derivatives relating to the sale of 14.2 mmbbl in the first half. This was part of a derivative transaction the Company entered into to hedge exposure to variability in 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 June 30, 2010, the residual amount of that hedging transaction was 23.3 mmbbl. Eni’s average gas realizations showed a decrease of 4.8% in the first half of 2010 due to time lags in oil-linked pricing formulae and weak demand in areas where gas is sold on a spot basis.

In the first half of 2010 the Gas & Power division reported adjusted operating profit of euro 1,896 million, a decrease of euro 157 million from the first half of 2009, down 7.6%, due to a lower performance delivered by the Marketing business (down 32.6%), partly offset by a better performance of the Italian regulated business (up 18%). Results from the Marketing activity were negatively affected by the same business trends as in the second quarter and did not take into account certain gains recorded in previous quarters on the settlement of non-hedging commodity derivatives amounting to euro 82 million which could be associated with the sale of gas and electricity occurred in the first half of 2010. In the first half of 2009, those gains amounted to euro 160 million which were not recognized in the operating profit of that period. Those gains were reflected in calculating the EBITDA pro-forma adjusted which represented |  | those derivatives as being hedges with associated gains recognized in each of the reporting periods where the associated sales occurred (see page below). Special items excluded from operating profit amounted to net charges of euro 94 million. These mainly related to the impact on fair value evaluation of certain non-hedging commodity derivatives in the Marketing business (euro 71 million), impairment of minor assets and provisions for redundancy incentives. Adjusted net profit for the first half of 2010 was euro 1,476 million, decreasing by euro 9 million from the first half of 2009 (down 0.6%) due to a lowered operating performance, partly offset by higher earnings reported by equity-accounted entities and a lowered tax rate (down by 3 percentage points).

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Marketing In the first half of 2010, the marketing business reported adjusted operating profit of euro 665 million representing a decrease of euro 322 million from the first half of 2009 (down 32.6%). In considering the impact associated with the above mentioned non-hedging commodity derivatives, the following factors had a negative effect on Marketing results: |  | reorganization that took place in 2009. The Transport activity increased the operating performance by euro 121 million, or 23.1% mainly due to: (i) lower operating cost related to in-kind remuneration of gas used in transport activity; (ii) lower amortization charges, related to the revision of the useful lives of gas pipelines (from 40 to 50 years); (iii) increased volumes transported on behalf of third parties, due to a slight recovery in domestic demand. Also the Distribution Business reported improved results (up euro 26 million) driven by a positive impact associated with a new tariff regime set by the Authority for Electricity and Gas intended to cover amortization charges. The storage business reported an adjusted operating profit of euro 134 million, a slight increase from the first half of 2009 (euro 126 million). International Transport This business reported an adjusted operating profit of euro 217 million for the first half representing an increase of euro 10 million, or 4.8%, from the first half of 2009.
(i) |  | Unfavorable trends in energy parameters provided in contractual oil-linked pricing formulae;
(ii) |  | Sharply lower sales volumes in Italy (down 4 bcm, or 18.9%) and declining margins as competitive pressures mounted.
These negatives were partly offset by the renegotiation of a number of long-term supply contracts and supply optimization measures. Regulated Businesses in Italy In the first half of 2010 these businesses reported an adjusted operating profit of euro 1,014 million, up euro 155 million from a year-ago, up 18%, due also to synergies achieved by integrating the businesses following the

EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization charges) on an adjusted basis is calculated by adding amortization and depreciation charges to adjusted operating profit which is also modified to take into account the impact associated with certain derivatives instruments as discussed below. This performance indicator includes the adjusted EBITDA of Eni’s wholly owned subsidiaries and Eni’s share of adjusted EBITDA generated by certain associates which are accounted for under the equity method for IFRS purposes. Snam Rete Gas’ EBITDA is included according to Eni’s share of equity (55.57% as of June 30, 2010, which takes into |  | account the amount of own shares held in treasury by the subsidiary itself) although this Company is fully consolidated when preparing consolidated financial statements in accordance with IFRS, due to its listed company status. Italgas SpA and Stoccaggi Gas Italia SpA results are also included according to the same share of equity as Snam Rete Gas (55.57%), due to the closing of the restructuring deal which involved Eni’s regulated business in the Italian gas sector. The parent company Eni SpA divested the entire share capital of the two subsidiaries to Snam Rete Gas. In order to calculate the pro-forma adjusted EBITDA, the adjusted operating profit of the Marketing business has

been modified to take into account the impact of the settlement of certain commodity and exchange rate derivatives that do not meet the formal criteria to be classified as hedges under the IFRS. These are entered into by the Company in view of certain amounts of gas and electricity that the Company expects to supply at fixed prices during future periods. The impact of those derivatives has been allocated to the pro-forma adjusted EBITDA relating to the reporting periods during which those supplies at fixed prices are |  | recognized. Management believes that the EBITDA pro-forma adjusted is an important alternative measure to assess the performance of Eni’s Gas & Power division, taking into account evidence that this division is comparable to European utilities in the gas and power generation sector. This measure is provided in order to assist investors and financial analysts in assessing the Eni Gas & Power divisional performance as compared to its European peers, as EBITDA is widely used as the main performance indicator for utilities. The pro-forma adjusted EBITDA is a non-GAAP measure under IFRS.

(a) |  | Excluding special items.

In the first half of 2010 the Refining & Marketing division reported an adjusted operating loss of euro 146 million, increasing by euro 95 million from the same period of the previous year, driven by lower refining margins as profitability of simple throughputs was impaired by lowered relative prices of products to oil feedstock costs due to weak industry fundamentals. This trend was partly offset by an improved profitability of complex throughputs, reflecting the re-opening of light-heavy crude differentials in the Mediterranean area in recent months. Another positive factor was the appreciation of the dollar over the euro in second quarter. Operating results were also affected by a lower operating performance delivered by the Marketing |  | activities in Italy, due to lower volumes sold driven by weak national demand. Special charges excluded from adjusted operating loss (euro 31 million) mainly related to environmental provisions, impairment of capital expenditures on assets impaired in previous reporting periods, partly offset by re-measurement gains recorded on fair value evaluation of certain non-hedging commodity derivatives. Adjusted net loss was euro 49 million (down euro 18 million from the first half of 2009) mainly due to a lower operating performance partly offset by higher earnings reported by equity-accounted entities.

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

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

Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Furthermore, finance charges on finance debt, interest income, gains or losses deriving from the evaluation of certain derivative financial instruments at fair value through profit or loss (as they do not meet the formal criteria to be assessed as hedges under IFRS, excluding commodity derivatives), and exchange rate differences are all excluded when determining adjusted net profit of each business segment. The taxation effect of the items excluded from adjusted operating or net profit is determined based on the specific rate of taxes applicable to each of them. The Italian statutory tax rate is applied to finance charges and income (34% is applied to charges recorded by companies in the energy sector, whilst a tax rate of 27.5% is applied to all other companies). Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them in order to facilitate a comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment. The following is a description of items that are excluded from the calculation of adjusted results. Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting. Special items include certain significant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified |  | as non-recurring items under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non recurring material income or charges are to be clearly reported in the management’s discussion and financial tables. Also, special items include gains and losses on re-measurement at fair value of certain non-hedging commodity derivatives, including the ineffective portion of cash flow hedges. Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition gains or losses on the fair value evaluation of the aforementioned derivative financial instruments, excluding commodity derivatives, and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charge pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production division). Finance charges or interest income and related taxation effects excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies. For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and reported net profit see tables below.

SUMMARIZED GROUP BALANCE SHEET

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

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Fixed assets Fixed assets amounted to euro 88,608 million, representing an increase of euro 8,882 million from December 31, 2009 reflecting exchange rate translation differences and capital expenditures incurred in the period (euro 7,107 million), partly offset by depreciation, depletion, amortization and impairment charges (euro 4,459 million) recorded in the period. Net working capital At June 30, 2010, net working capital amounted to a negative euro 7,210 million, representing a decrease of euro 1,268 million from December 31, 2009, mainly due to: higher tax payables and provisions for net deferred tax liabilities (up euro 2,071 million) related to income taxes accrued for the period; higher trade payables partly offset by increased trade receivables, reflecting the impact of higher prices of commodities, resulting in an increase of euro 881 million. These effects were partly offset by: an increase in oil, gas and petroleum products inventories (up euro 1,146 million) as a result of a recovery in oil and products prices in the evaluation of the inventories on the basis of the weighted-average cost method and higher volumes of gas input to storage compared with the off-takes made in winter months; a reduction in the item other current assets and liabilities (down euro 1,073 million) associated with a positive change of euro 234 million (from a negative euro 530 million to a negative euro 296 million; respectively |  | down euro 312 million and euro 177 million net of taxes) in fair value of certain commodity derivatives instruments Eni 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 mmboe, decreasing to 23.3 mmboe as of the end of June 2010 due to settled transactions up to the end of the first half 2010. Also other non-current assets, which were comprised in the balance above, included as accounted in Eni 2009 financial statements a deferred cost classified as a non current asset which related to amounts of gas which were collected below minimum take quantities for the year 2009 as provided for by take-or-pay clauses contained in certain long-term gas purchase contracts. The Company plans to collect the underlying gas volumes beyond a twelve-month period. The amount recognized in the balance sheet corresponding to a receivable in-kind was stated at the lower of purchase cost and net realizable value as of the end of the period based on realized prices on sales to different customer segments incurred in the previous twelve-month period (euro 255 million). Net assets held for sale including related liabilities (euro 331 million) mainly related to the following assets: certain oil&gas properties in Italy which were contributed in kind to two subsidiaries Società Padana Energia SpA and Società Adriatica Idrocarburi SpA, and the subsidiary Gas Brasiliano Distribuidora.

Return On Average Capital Employed (ROACE)

Return on Average Capital Employed for the Group, on an adjusted basis is the return on the Group average capital invested, calculated as ratio of net adjusted profit before minority interest, plus net finance charges on net borrowings net of the related tax effect, to net average capital employed. The tax rate applied on finance charges is the Italian statutory tax rate (34% is applied to charges recorded by companies in the energy sector, whilst a tax rate of 27.5% is applied to |  | other companies). The capital invested as of period end used for the calculation of net average capital invested is obtained by deducting inventory gains or losses in the period, net of the related tax effect. ROACE by division is determined as ratio of adjusted net profit to net average capital invested pertaining to each division and rectifying the net capital invested as of period-end, from net inventory gains or losses (after applying the division specific tax rate).

Leverage and net borrowings

Leverage is a measure used by management to assess the Company’s level of indebtedness. It is calculated as ratio of net borrowings – which is calculated by excluding cash and cash equivalents and certain very liquid assets from financial debt to shareholders’ equity, including minority |  | interest. Management periodically reviews leverage in order to assess the soundness and efficiency of the Group balance sheet in terms of optimal mix between net borrowings and net equity, and to carry out benchmark analysis with industry standards.

SUMMARIZED GROUP CASH FLOW STATEMENT AND CHANGE IN NET BORROWINGS

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

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

RISK FACTORS AND UNCERTAINTIES

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; (iii) the liquidity risk deriving from the risk that suitable sources of funding for the Group’s operations may not be available; (iv) the Country risk in the upstream business; (v) the operational risk; (vi) the possible evolution of the Italian gas market; (vii) the specific risks deriving from exploration and production activities. Financial risks are managed in respect of guidelines defined by the parent company, targeting to align and coordinate Group companies’ policies on financial risks. 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 conducting finance, treasury and risk management operations based on separate entities: 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 that has the mandate to manage and monitor solely commodity derivative contracts. 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 trading certificates according to the European Union Emission Trading Scheme. The commodity risk is managed by each business unit with Eni Trading & Shipping ensuring 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 a speculative basis. 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 accordance with value-at-risk techniques. These techniques make a statistical assessment of the market risk on 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, 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 such kinds of market risks. With regard to the commodity risk, Eni’s policies and guidelines define

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

rules to manage this risk aiming at the optimization of core activities and the pursuing of preset targets of industrial margins. The maximum tolerable level of risk exposure is pre-defined in terms of value-at-risk in connection with trading and commercial activities, 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 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 three different market risks, whose 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 US 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 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 (translation risk). Generally, an appreciation of the US dollar versus the euro has a positive impact on Eni’s results of operations, and vice-versa. 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 VAR 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, with a 99% confidence level and a 20-day holding period. Commodity risk Eni’s results of operations are affected by changes in the prices of commodities. A decrease in oil and gas prices generally has a negative impact on Eni’s results of operations and vice-versa. 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, 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, with a 95% confidence level and a one-day holding period. The following table shows amounts in terms of value at risk, recorded in the first half of 2010 (compared with the first half of 2009) relating to interest rate and exchange rate risks in the first section, and commodity risk in the second section. VaR values are stated in US dollars, the currency used in oil products markets.

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 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. The monitoring activity of credit risk exposure is performed at the Group level according to set guidelines and measurement techniques that establish counterparty limits and systems to monitor exposure against limits and report regularly on those exposures. Specifically, credit risk exposure to multi-business clients and exposures higher than the limit set at euro 4 million are closely monitored. Monitoring activities do not include retail clients and public administrations. The assessment methodology assigns a score to individual clients based on publicly available financial data and capital, |  | profitability and liquidity ratios. Based on those scores, an internal credit rating is assigned to each counterparty who is accordingly allocated to its proper risk category. The Group risk categories are comparable to those prepared by the main rating agencies on the marketplace. The Group’s internal ratings are also benchmarked against ratings prepared by a specialized external source. 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. Those are the sole Group entities entitled to be party to financial

transactions due to 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. See Note 2 to the condensed consolidated financial statements for a disclosure about changes in the loss provisions for doubtful accounts in the first half of 2010. 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 market place 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 also targeting to increase the flexibility of funding facilities. In particular in the first half of 2010, Eni issued bonds addressed to institutional investors for euro 1 billion. The above mentioned actions aimed at ensuring availability of suitable sources of funding to fulfill short-term commitments and due obligations 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. As of June 30, 2010, Eni maintained short-term committed and uncommitted unused borrowing facilities of euro 11,882 million, of which euro 2,900 million were committed, and long-term committed unused borrowing facilities of euro 2,850 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 euro 9,754 million were drawn as of June 30, 2010. The Group has debt ratings of A+ and A-1 respectively for long and short-term debt, outlook stable, assigned by Standard & Poor’s and Aa2 and P-1, outlook negative, assigned by Moody’s. The tables below summarize the Group main contractual obligations for finance debt repayments, including expected payments for interest charges, and trade and other payables maturities.

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 certain arrangements to purchase goods or services that are enforceable and legally binding and that specify all significant terms. Such arrangements include non-cancelable, long-term contractual obligations to secure access to supply and transport of natural gas, which include take-or-pay clauses 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 and on the basis of the long-term market scenarios used by Eni for planning purposes to minimum take and minimum ship quantities. The table below summarizes the Group principal contractual obligations as of the balance sheet date, shown on an undiscounted basis.

Country risk Substantial portions of Eni’s hydrocarbons reserves are located in Countries outside the EU and North America, certain of which may be politically or economically less stable than EU or North American. At December 31, 2009, approximately 80% of Eni’s proved hydrocarbons reserves were located in such Countries. Similarly, a substantial portion of Eni’s natural gas supplies comes from Countries outside the EU and North America. In 2009, approximately 60% of Eni’s domestic supply of natural gas came from such Countries. Developments in the political framework, economic crisis, social unrest can compromise temporarily or permanently Eni’s ability to operate or to economically operate in such Countries, and to have access to oil and gas reserves. Further risks associated with activities in those Countries are represented by: (i) lack of well established and reliable legal systems and uncertainties surrounding enforcement of contractual rights; (ii) unfavorable developments in laws and regulations leading to expropriation of Eni’s titles and mineral assets, changes in unilateral contractual clauses reducing the value of Eni’s assets; (iii) restrictions on exploration, production, imports and exports; (iv) tax or royalty increases; (v) civil and social unrest leading to sabotages, acts of violence and incidents. While the occurrence of these events is unpredictable, it is possible that they can have a material adverse impact on Eni’s financial condition and results of operations. Eni periodically monitors political, social and economic risks of approximately 60 Countries where it has invested, or, with regard to upstream projects evaluation, where Eni is planning to invest in order to assess returns of single projects based also on the evaluation of each Country’s risk profile. Country risk is mitigated in accordance with guidelines on risk management defined in the procedure "Project risk assessment and management". In the most recent years, unfavorable developments in the regulatory framework, mainly regarding tax issues, have been implemented or announced also in EU Countries and in North America. |  | Operational risk Eni’s business activities conducted in and outside Italy are subject to a broad range of laws and regulations, including specific rules concerning oil and gas activities currently in force in Countries in which it operates. In particular, those laws and regulations require the acquisition of a license before exploratory drilling may commence and compliance with health, safety and environment standards. Environmental laws impose restrictions on the types, quantities and concentration of various substances that can be released into the environment and on discharges to surface and subsurface water. In particular Eni is required to follow strict operating practices and standards to protect biodiversity when exploring for, drilling and producing oil and gas in certain ecologically sensitive locations (protected areas). Breach of environmental, health and safety laws exposes employees to criminal and civil liability and in the case of violation of certain rules regarding safety on the workplace also companies 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 and expenses and liabilities that Eni may incur in relation to compliance with environmental, health and safety laws and regulations are expected to remain material to the Group’s results of operations or financial position in future years. Recently enacted regulations on safety and health in the workplace in Italy impose a new array of obligations to the Company operations, particularly regarding contractors. New regulations prescribe that a company adopts certified operational and organizational systems whereby the Company can discharge possible liabilities due to a violation of health and security standards on condition that adopted operational systems and processes worked properly and were effective. Eni has adopted guidelines for assessing and managing

health, safety and environmental (HSE) risks, with the objective of protecting Eni’s employees, the populations involved in its activity, contractors and clients, and the environment and being in compliance with local and international rules and regulations. Eni’s guidelines prescribe the adoption of international best practices in setting internal principles, standards and solutions. The ongoing process for identifying, evaluating and managing HSE operations in each phase of the business activity is performed through the adoption of procedures and effective pollution management systems tailored to the peculiarities of each business and industrial site and on steady enhancement of plants and process. Additionally, coding activities and procedures on operating phases allow to reduce the human component in the plant risk management. Operating emergencies that may have an adverse impact on assets, people and the environment are managed by the business units for each site. These units manage the HSE risk in a systematic way that involves having emergency response plans in place with a number of corrective actions to be taken that minimize damage in the event of an incident. In the case of a major crisis, Divisions/Entities are assisted by the Eni Unit of Crisis to deal with the emergency through a team which has the necessary training and skills to coordinate in a timely and efficient manner resources and facilities. The integrated management system of health, safety and environmental matters is supported by the adoption of Eni’s Model of HSE operations in all the Division and companies of the Eni Group. This is a procedure based on an annual cycle of planning, implementation, control, review of results and definition of new objectives. The model is directed towards the prevention of risks, the systematic monitoring and control of HSE performance, in a continuous improvement cycle (Deming cycle). Eni is reaching the goal of total certification of its plants. Industrial and commercial sites of the R&M segment have been certified as ISO 14001, and six of them are EMAS certified; in the petrochemical segment facilities are certified under ISO 14001, EMAS and OHSAS 18001. EniPower power stations are EMAS certified, while in other segments facilities are mainly certified under ISO 14001 and OHSAS 18001. The system for monitoring HSE operational risks is based on the monitoring of HSE indicators at quarterly intervals and on an audit plan addressed to three levels: HSE Corporate, HSE business unit and at site level consisting of: internal audits of management systems (performed by Eni employees or external consultants); |  | audits for the confirmation or renewal of certification of management systems performed annually by external certifying entities; control of compliance with existing HSE regulations; specific audits on relevant issues (e.g. following events/ accidents/reported failures). Eni provides a program of specific training and development to its HSE staff in order to: promote the execution of behaviors consistent with guidelines; drive people’s learning growth process by developing professionalism, management and corporate culture; support management knowledge and control of HSE risks. In addition to the Company’s system for monitoring, managing and responding to HSE risks and issues which has been adopted by all Group subsidiaries, Eni has entered into insurance arrangements trough its shareholding in the OIL insurance Ltd and with other insurance partners in order to limit possible economic impacts associated with damages occurring in case of both onshore and offshore incidents. Covered losses vary depending on nature and type of circumstances; however underlying amounts represent significant shares of the plafond granted by insuring companies. The recent incident at a 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 US 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 US Government has imposed a moratorium on certain offshore drilling activities through November 30, 2010, and similar actions may be taken by governments elsewhere in the world. New regulations and legislation, as well as evolving practices, would 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. Eni’s management is currently rescheduling certain projects in the Gulf of Mexico due to delays in linking wells to production facilities which will impact the Company’s production outlook for the year. In addition, the Group has incurred operating costs related to certain drilling rigs which have been booked before the moratorium in the second quarter of 2010. The overall impact of that inactivity on Eni’s results of operations for the full year 2010 will depend on the Company’s ability to reschedule its operations away from the Gulf of Mexico to other areas.

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Risks and uncertainties associated with the competitive environment in the natural gas market Management expects that the competitive environment will remain extremely uncertain and volatile in the European gas market for the remaining part of the year 2010 and beyond. Based on ongoing trends, management has increased its full-year projections of Italian and European gas demand growth to a rate of 3.8% and 2.2%, respectively, up from a previous forecast of stable demand in Italy and an increase rate of 1.4% in Europe. Management forecasts that demand will grow at a faster pace than initially planned also in 2011 and 2012. However, market fundamentals are expected to remain weak over that time span as gas oversupply is showing no signs of relief. A number of factors help explain the current imbalances, namely large availability of import capacity related to the build-up of new infrastructures, production ramp-ups specially in Norway and large amounts of LNG following the coming online of a number of projects (LNG trains in Qatar, Yemen, Indonesia and Russia), as well as development of non-conventional gas resources in the United States which have reduced the Country dependence on LNG imports. The condition of oversupply is highlighted by dramatically lowered spot prices of gas marketed on the main continental hubs, coupled with increased liquidity on the marketplace. The main consequence of those trends is represented by de-coupling trends in gas spot prices quoted on the continental hubs vs. long-term prices correlated to oil-linked formulas that index gas prices in long-term supply contracts to crude oil and refined products prices, resulting in negative spreads. This development represents a risk factor for gas operators, including Eni, as their cost structure is linked to the price of oil while their sales are increasingly influenced by spot prices quoted on the continental hubs. Management believes that a better balance between demand and supply and a consequent re-coupling of trends in spot prices vs. oil-linked prices will be achieved in 2013 at the earliest. A number of uncertainties weigh on this forecast including the pace of the economic recovery in Europe, the impact associated with the adoption of energy-saving habits, the need for reducing greenhouse gas emissions, rising competition from renewable or alternative sources of energy, also taking into consideration the commitment of EU Member States to achieve the targets set in the so-called package "20-20-20 European Policy" by 2020. On the positive side, the recovery of the |  | Asian economy will absorb part of LNG supplies, while on part of gas upstream producers it is probable that a number of gas reserve development projects will be rescheduled. Management believes those trends might negatively affect results of operations and cash flow of Eni’s gas business in the second half and also the next two years. Current negative trends in the competitive environment may impair Eni’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. These contracts will ensure approximately 62.4 bcm of gas availability in 2010 (excluding the contribution of other subsidiaries and associates) 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 predetermined volumes of gas in each year of the contractual term or, in case of failure, to pay the whole price, or a fraction, of 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 in place in the year of the off-take.

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Similar considerations apply to ship-or-pay contractual obligations. Management believes that the current outlook for gas demand and large gas availability on the marketplace, the possible evolution of sector-specific regulation, as well as the de-coupling between trends in oil linked-prices vs. spot prices, represent risks factors to the Company’s ability to fulfill its minimum take obligations associated with its long-term supply contracts. Management expects that the Company will experience increasing exposure to the strategic risk associated with growing adoption on the market place of selling formulae 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. This trend could become a structural element in the gas market. In 2009 Eni incurred the take-or-pay clause as the Company collected lower volumes than its minimum take obligations for the year thus recognizing a trade payable for the uncollected amount of gas up to the minimum off-take volumes provided in the relevant contractual arrangements. Considering current trends and imbalances in the gas market and factoring in the level of sales volumes achieved in the first half of 2010 (down by 6% driven by a 19% loss in Italy), management believes that for the full year 2010 the Company will fail to fulfill its minimum take contractual obligations associated with significant volumes of gas, thus incurring the take-or-pay clause. The impacts on the financial statements and eventually on the Company’s liquidity associated with the incurrence of the take-or-pay clause will be recognized as of end of the contractual year (the thermal or the calendar year as the case may be). Furthermore, management expects that the Company will continue incurring the take-or-pay clause associated with significant gas volumes over the next two years, unless current oversupply conditions improve substantially. If 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 offtake 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 prices for the four-year plan and subsequent years, volumes for which an obligation to pay cash |  | advances might arise due to take or pay clauses will be off-taken within contractual terms, thus recovering cash advances. Even if financing associated with cash advances is factored in, the net present value associated with those long-term 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. In the medium term Eni intends to preserve the profitability and cash flow generation of its gas marketing operations. A number of initiatives have been identified, including: maximizing gas sales volumes leveraging on the multiple presence in a number of markets; market knowledge, the integration with Distrigas commercial operations and supply portfolio (which is not expected to have take-or-pay obligations in future years) and marketing policies aimed at increasing Eni’s market share in Europe; renegotiating the main long-term supply contracts by exercising the contractual right to amend terms and conditions of the contracts as provided by specific contractual clauses in case of significant changes in the market environment, as those that have been occurring from the second half of 2008. Certain of these renegotiations were finalized early in 2010 with a positive impact both on results of operations and Eni’s future commercial plans as the Company obtained more flexibility in its marketing operations; implementing a dynamic portfolio management aimed at optimizing value of assets (gas supply contracts, customer base, market position) by: ensuring the balance between supply and sale programs over periods of up to four years and monthly schedules of needs and physical flows; managing market risks (commodity, volumes); unlocking value by leveraging opportunities associated with the flexibility provided by the Company’s portfolio of long term contracts. Management plans to increase the amount of derivatives transactions to safeguard assets’ value. This could increase future earnings’ volatility in case those derivatives do not qualify for hedge accounting as defined by IAS 39. Specifically, management plans for: (i) entering cash flow hedge transactions to protect the Company’s future cash flows on highly probable future sale transactions from exposure to volatility in commodity prices. Management expects such a kind of risk to be associated with on one side different market

trends for supply oil-linked costs and hub-related selling prices, and on the other side eventual mismatching between oil-linked pricing formulae for supply costs and revenues (strategic risk). These instruments are expected to be closely related to the underlying commodity; (ii) entering derivative transactions for the purpose of taking advantage of different market price trends in order to increase Eni’s selling margins, as well as forward gas supplies on the continental hubs which the Group expects to settle both through physical delivery or on a net basis; (iii) entering derivative transactions part of a proprietary trading which will be carried out in compliance with strict risk policies. Those transactions will be built around the expertise and trading capabilities which have been consolidated following Distrigas acquisition. - Launching of innovative pricing formulas and improving the quality of services on the core Italian market; - Reduction in the cost-to-serve; - Monitoring and effectively managing working capital requirements. Risks associated with sector-specific regulations in Italy The regulated period in the natural gas market as defined by Legislative Decree No. 164/2000 will be effective until December 31, 2010. In particular, the Decree is going to expire in relation to antitrust thresholds on gas volumes (imported or domestically produced) input into the national transport network and on marketed gas volumes to final customers by each operator. Management expects that these antitrust thresholds will be replaced by new gas volumes thresholds in terms of market share of each operator. This has been anticipated by a framework decree approved by the Italian Government on April 23, 2010, implementing article 30, paragraph 6 of the Law No. 99, issued on July 23, 2009. The framework decree is undergoing the necessary institutional steps. The framework decree introduces ceiling on the market share of each Italian gas operators, incentives to third parties for building new storage capacity and certain measures to improve market liquidity (for further information see "Operating Review of the Gas & Power Division - Paragraph "Regulation"). The Group is monitoring evolutions in this matter with a view of assessing any possible financial or economic impacts associated with the proposed measures, while complying with legislation in effect. |  | Further material aspects regarding the Italian gas sector regulations are the regulated access to infrastructures (transport backbones, storage fields, distribution networks and LNG terminals), the provision that activities relating to infrastructures are to be managed by separate legal entities within vertically-integrated group companies, the provision forbidding a controlling entity from interfering in the decision-making process of its subsidiaries managing gas transport, storage and distribution activities by July 1, 2008 (as defined by Decision No. 11/2007 and updated by Resolution No. 253/2007 of the Authority for Electricity and Gas) and the circumstance that the 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 code for each regulated activity, monitoring natural gas prices and setting pricing mechanism for supplies to residential users consuming less than 200,000 cm/y. Those clients have right to obtain gas from their suppliers at a regulated tariff. Referring to this last issue, decisions made by the Authority for Electricity and Gas may limit the ability of gas resellers to transfer cost increases of the raw material to final customers, given the current pricing mechanism which indexes the cost of gas to crude oil and derivatives prices in supplies to residential customers. The Authority has recently updated the indexation mechanism based on Resolution No. 64/2009. The new indexation mechanism provides that changes in a preset basket of hydrocarbons are transferred to the price of supplies to residential and commercial users. Also a floor has been established in the form of a fixed amount that applies only at certain low level of international prices of hydrocarbons. Furthermore, on March 26, 2010, the Authority for Electricity and Gas published a consultation document (ARG/gas 47/2010) regarding certain proposed amendments to the current mechanism that is used to update the raw material cost component in supplies to residential users. Following the consultation document (DCO 5/2010), the Authority resolved with Resolution ARG/gas No. 89/2010 to provide a fixed reduction, lowering from 1 to 0.925 the measure whereby variations in the cost of gas are transferred to the final price in supplies to residential users to be applied to the thermal year October 1, 2010-September 30, 2011. This resolution will negatively affect Eni’s future results and cash flows, except for any possible outcome of challenging the resolution before an administrative court. Also certain provisions of law may limit the Company’s ability to set commercial margins. Specifically, Law

ENI INTERIM CONSOLIDATED REPORT / FINANCIAL REVIEW AND TREND INFORMATION

Decree No. 112 enacted in June 2008 forbids energy companies like Eni to pass to prices to final customers the higher income taxes incurred in connection with a supplemental tax rate of 6.5 percentage points introduced by the same decree on energy companies with a yearly turnover in excess of euro 25 million. The Authority for Electricity and Gas is in charge of monitoring compliance with this rule. The Authority has subsequently established with a set of deliberations that energy companies have to adopt effective operational and monitoring systems in order to prevent unlawful increases in final prices of gas. Other risk factors and uncertainties deriving from the regulatory framework currently in force in the Italian gas sector are associated with the 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). For more detail on this risk factor see Eni’s Annual Report 2009 - Operating Review of the Gas & Power division - Paragraph Risk Factors, as there were no material developments on this matter in the first half of 2010. Recently, the Italian administrative authorities released a number of resolutions intended to favor development of a gas spot market in Italy with an efficient level of flexibility and liquidity. As part of this framework, a number of gas release measures have been enacted. Those measures have strongly affected Eni’s marketing activity in Italy. The latest development on this matter has been Legislative Decree No. 78/2009 which obliged Eni to make additional sales 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 Authority (Eni considering this point discriminatory, filed a claim to 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 (in a report to the Parliament on the situation of the gas and electricity market in Italy as provided in Resolution PAS 3/2010 and again in the above mentioned consultation document about the pricing mechanism in the residential sector), Eni |  | cannot exclude the possibility that the Company will be forced to implement additional gas release programs. It is worth mentioning that the new framework decree intended to increase competitiveness in the gas market, provide a mechanism of gas release for Eni in case of failure to comply with the mandatory ceiling on the market share. Measures aimed at increasing competitiveness in the Italian gas market represent risk factors and uncertainties to Eni’s gas business. Management believes that it is possible that any developments in that matter may negatively affect the Company’s expected results of operations and cash flow of its gas business in the second half of the year and in future years. Lastly, the adoption of the European Directive 2009/73/EC comprising the third package on the internal gas market represents a risk factor and an uncertainty as Eni is engaged in the regulated transport business. The Directive provides for three independent transportation operator regimes: separation of transportation network assets ("ownership unbundling"); independent system operator and independent transmission operator (for further information see the Operating Review - Gas & Power Division - Regulation). The choice among alternate solutions is the responsibility of Member States, during the transposition expected by March 2011. The Group is monitoring developments in this matter with a view of assessing any possible financial or economic impacts associated with the change, while complying with legislation in effect on functional unbundling (as defined by Resolution No. 11/2007 of the Authority for Electricity and Gas). Eni is not able to predict developments on this matter but Eni cannot exclude that implementation of European Directive 2009/73/EC in Italy or possible developments in the regulatory framework of the natural gas market in Italy will result in Eni relinquishing control over or divesting its interest in Snam Rete Gas. Eni’s interest in Snam Rete Gas (52.54%) currently accounts for approximately 12% of the Group’s total assets, 2% of the Group’s total revenues and 11% of the Group’s operating profits. Specific risks associated with exploration and production of oil and natural gas Exploration and production of oil and natural gas requires high levels of capital expenditure and entails particular economic risks. It is subject to natural hazards and other uncertainties including those relating to

the physical characteristics of oil or natural gas fields. Exploratory activity involves numerous risks including the risk of dry holes or failure to find commercial quantities of hydrocarbons. 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 commerciality, sanctioning a development project and building and commissioning relating facilities. As a consequence, rates of return of such long lead-time projects are exposed to the volatility of oil and gas prices and the risk of an increase in developing and lifting costs, resulting in lower rates of return. This set of circumstances is particularly important to those projects intended to develop reserves located in deep water and harsh environments, where the majority of Eni’s planned and ongoing projects is located. 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. Main trends and uncertainties affecting the second half of the year Eni expects energy markets to remain uncertain and volatile in the second half of the year in light of the risks still surrounding the solidity and sustainability of the global economic recovery. Oil prices fluctuations affect Eni’s operating segments in different ways. High oil prices benefit the results of Eni’s Exploration & Production segment, while the Refining & Marketing and the Petrochemical divisions are exposed to relative movements in prices of oil and products and the speed at which the prices of products adjust to reflect change in the cost of oil-based feedstock. Normally, a time lag occurs between movements in prices of oil and those of refined and petrochemical products. As a consequence, in a period of rapidly escalating feedstock costs, margins on refined and petrochemical products are negatively affected. In the first half of 2010 the Refining & Marketing segment recorded an operating loss due to higher costs of oil-based feedstock that it was unable to pass to end prices of products pressured by weak demand, high inventories and excess capacity. In addition, the increased oil price triggered higher costs of energy utilities which are typically indexed to it. However, |  | results for the second quarter of 2010, particularly the months of May and June, improved significantly from a year ago quarter, with operating losses being significantly reduced. This trend reflected a recovery in the light and heavy crude differentials that benefited Eni’s complex refineries which were further upgraded by the coming on stream of the new hydro-cracker at the Taranto plant. Looking forward, management expects that the refining scenario will remain highly uncertain and volatile, while industry fundamentals will be somewhat supported by capacity rationalizations and downsizings. Against this backdrop, management is cautiously optimistic about the possibility that an ongoing recovery in refining margins will consolidate in the remaining part of the year which could drive Eni’s refining activity to improve profitability in the second half. This would determine a sizeable reduction in the business’ operating loss for the full year compared to last year. Results of the marketing of refined products are exposed to the risks of a contraction in the demand for fuels, in particular on the domestic market, due also to the cautious attitude of consumers in light of the slowness of economic recovery. In addition to volatile oil-based feedstock costs, Eni’s petrochemicals operations are exposed to the cyclicality of demand due to the commoditized nature of Eni’s product portfolio and underlying weaknesses in the industry plagued by low entry-barriers, excess capacity and intense competitive pressures. These drivers helped explain the substantial amounts of operating losses that have been accumulated by Eni’s petrochemicals operation in the last couple of years. However, in the first half of 2010 business conditions have progressively improved and the segment managed to significantly reduce the pace of losses (down from euro 257 million to euro 70 million; up by 73%). While high feedstock costs continued to pressure product margins, the factors behind that improvement were a recovery in sales volumes driven by a global economic upturn, as well as cost reduction initiatives and plant rationalizations. Notwithstanding there persist risks and uncertainties associated with trends in the global economy and rapidly escalating oil costs, management expects to deliver on the planned targets of sizeable reduction in operating losses and the cash burn rate of the petrochemicals business for the full year. Volatile oil prices represent an uncertainty factor in view of achieving the Company’s operating targets of production growth and reserve replacement due to the large presence of Production Sharing Agreements in Eni’s portfolio. Under such contracts, the Company

is entitled to receive a portion of the production, the sale of which should cover expenditures incurred and earn the Company a share of profit. Accordingly, the higher the reference prices for crude oil used to determine production and reserves entitlements, the lower the number of barrels to cover the same dollar amounts hence the amounts of booked production and reserves; and vice versa. 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 65 $/bbl adopted in the four-year plan 2010-2013. However, this sensitivity analysis only applies to small deviations from the 65 $/bbl scenario and the impact on Eni’s production may |  | increase more than proportionally as the deviation increases. This sensitivity analysis relates to the existing Eni portfolio and might vary in the future. The Engineering & Construction segment plans to increase its order backlog and economic returns, thanks to a 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 distinctive assets in 2010 and 2011 coupled with the size and quality of the backlog and the strong operating performance on projects, underpin expectations for a further significant strengthening of Saipem’s competitive position in the medium-term.

OUTLOOK

In what remains an uncertain and volatile energy environment, Eni forecasts a modest improvement in global oil demand and a Brent price of 76 $/bbl for the full year 2010. Considering ongoing trends, management expects that gas demand in Europe and Italy will recover at a faster pace than the Company’s base case assumptions following the steep decline suffered in 2009 in the industrial and power generation sectors. In the refining business, underlying fundamentals are expected to remain weak as highlighted by margins volatility. Against this backdrop, key volumes trends for the year are expected to be the following: Production of liquids and natural gas is forecast to be in line with 2009 (production in 2009 was 1.769 mmboe/d). This estimate is based on the Company’s assumption for a Brent price of 76 $/bbl for the full year, the same level of OPEC restrictions as in the first half of 2010 and asset disposals underway. It excludes the effect of updating the gas conversion rate. Growth will be driven by continuing field start-ups, mainly in Italy, Congo and Norway and marginally the Zubair project in Iraq, as well as production ramp-up at the Company’s recently started fields, mainly in Nigeria and Angola. These additions will be offset by mature field declines, lower gas uplifts in Libya due to oversupply conditions on the European market and rescheduling of certain projects expected in the Gulf of Mexico as consequence of the accident occurred at the BP-operated Macondo well; Worldwide gas sales are forecasted to decrease compared with 2009 (approximately 104 bcm were achieved in 2009). Increasing competitive pressures, mainly in Italy, are expected to be partly offset by an expected recovery in European gas demand. Other positive trends include a benefit associated with integrating Distrigas operations and the optimization of its supply portfolio, including re-negotiation of long-term supply contracts; |  | Regulated businesses in Italy will benefit from the pre-set regulatory return on new capital expenditures and cost savings from integrating the full chain of transport, storage and distribution activities; Refining throughputs on Eni’s account are planned to increase compared with 2009 (actual throughputs in 2009 were 34.55 mmtonnes) due to a higher capacity utilization rate of Eni’s refineries partly offset by lowered volumes on third party refineries reflecting the Company’s decision to terminate certain processing agreements. In a challenging trading environment, management forecasts an improvement in refining margins from a year ago, leveraging on better spreads between light and heavy crudes as well as initiatives for efficiency enhancement and margin expansion; Retail sales of refined products in Italy and the rest of Europe are expected decline slightly from 2009 (12.02 mmtonnes in 2009) reflecting sluggish consumption. Marketing initiatives are planned in order to support sales volumes and margins in the Italian retail market and to develop the Company’s market share in European markets; The Engineering & Construction business is expected to see solid results due to a robust order backlog. In 2010, management plans to make capital expenditures slightly higher compared with 2009 (euro 13.69 billion were invested in 2009) as a result of interventions aimed at optimizing production and the impact of the appreciation of the US dollar over the euro. Capital expenditures will mainly be directed to the development of oil and natural gas reserves, exploration projects, the upgrading of construction vessels and rigs, and the upgrading of natural gas transport infrastructure. Management has planned a number of measures designed to ensure the achievement of a ratio of net borrowings to total equity (leverage) which will adequately support a strong credit rating.

Glossary

The glossary of oil and gas terms is available on Eni’s web page at the address www.eni.com. Below is a selection of the most frequently used terms. FINANCIAL TERMS Dividend Yield Measures the return on a share based on dividends for the year. Calculated as the ratio of dividends per share of the year and the average reference price of shares in the last month of the year. Generally, companies tend to keep a constant dividend yield, as shareholders compare this indicator with the yield of other shares or other financial instruments (e.g. bonds). Leverage Is a measure of a company’s debt, calculated as the ratio between net financial debt and shareholders’ equity, including minority interests. ROACE Return On Average Capital Employed Is the return on average capital invested, calculated as the ratio between net income before minority interests, plus net financial charges on net financial debt, less the related tax effect and net average capital employed. TSR Total Shareholder Return Measures the total return of a share calculated on a yearly basis, keeping account of changes in prices (beginning and end of year) and dividends distributed and reinvested at the ex-dividend date. |  | OIL AND NATURAL GAS ACTIVITIES Average reserve life index Ratio between the amount of reserves at the end of the year and total production for the year. Barrel Volume unit corresponding to 159 liters. A barrel of oil corresponds to about 0.137 metric tons. Boe (Barrel of Oil Equivalent) Is used as a standard unit measure for oil and natural gas. From April 1, 2010, Eni has updated the conversion rate of gas to 5,550 cubic feet of gas equals 1 barrel of oil (it was 5,742 cubic feet of gas per barrel in previous reporting periods). Concession contracts Contracts currently applied mainly in Western Countries regulating relationships between States and oil companies with regards to hydrocarbon exploration and production. The company holding the mining concession has an exclusive on mining activities and for this reason it acquires a right on hydrocarbons extracted, against the payment of royalties to the State on production and taxes on oil revenues. Condensates These are light hydrocarbons produced along with gas, that condense to a liquid state at normal temperature and pressure for surface production facilities.

Contingent resources Amounts of oil and gas estimated at a given date that are potentially recoverable by means of development projects that are not considered commercially recoverable due to one or more contingency. Deep waters Waters deeper than 200 meters. Development Drilling and other post-exploration activities aimed at the production of oil and gas. Elastomers (or Rubber) Polymers, either natural or synthetic, which, unlike plastic, when stress is applied, return, to a certain degree, to their original shape, once the stress ceases to be applied. The main synthetic elastomers are polybutadiene (BR), styrene-butadiene rubber (SBR), ethylene-propylene rubber (EPR), thermoplastic rubber (TPR) and nitrylic rubber (NBR). Enhanced recovery Techniques used to increase or stretch over time the production of wells. EPC (Engineering, Procurement, Construction) A contract typical of onshore construction of large plants in which the contractor supplies engineering, procurement and construction of the plant. The contract is defined "turnkey" when the plant is supplied for start-up. EPIC (Engineering, Procurement, Installation, Commissioning) A contract typical of offshore construction of complex projects (such as the installation of production platforms or FPSO systems) in which the global or main contractor, usually a company or a consortium of companies, supplies engineering, procurement, construction of plant and infrastructure, transport to the site and all preparatory activities for the start-up of plants. Exploration Oil and natural gas exploration that includes land surveys, geological and geophysical studies, seismic data gathering and analysis, and well drilling. FPSO vessel Floating, Production, Storage and Offloading system made up of a large capacity oil tanker including a large hydrocarbon treatment plant. This system, moored at the bow in order to maintain a geostationary position, is in fact a temporary fixed platform linking the underwater wellheads to the |  | treatment, storage and offloading systems onboard by means of risers from the seabed. Infilling wells Infilling wells are wells drilled in a producing area in order to improve the recovery of hydrocarbons from the field and to maintain and/or increase production levels. LNG Liquefied Natural Gas obtained through the cooling of natural gas to minus 160 °C at normal pressure. The gas is liquefied to allow transportation from the place of extraction to the sites at which it is transformed and consumed. One ton of LNG corresponds to 1,400 cubic meters of gas. LPG Liquefied Petroleum Gas, a mix of light petroleum fractions, gaseous at normal pressure and easily liquefied at room temperature through limited compression. Mineral Potential (Potentially recoverable hydrocarbon volumes) Estimated recoverable volumes which cannot be defined as reserves due to a number of reasons, such as the temporary lack of viable markets, a possible commercial recovery dependent on the development of new technologies, or for their location in accumulations yet to be developed or where evaluation of known accumulations is still at an early stage. Mineral Storage Volumes of natural gas required for allowing optimal operation of natural gas fields in Italy for technical and economic reasons. Modulation Storage Volumes of natural gas required for meeting hourly, daily and seasonal swings of demand. Natural gas liquids Liquid or liquefied hydrocarbons recovered from natural gas through separation equipment or natural gas treatment plants. Propane, normal-butane and isobutane, isopentane and pentane plus, that used to be defined natural gasoline, are natural gas liquids. Network Code A code containing norms and regulations for access to, management and operation of natural gas pipelines. Offshore/Onshore The term offshore indicates a portion of open sea and, by induction, the activities carried

out in such area, while onshore refers to land operations. Olefins (or Alkenes) Hydrocarbons that are particularly active chemically, used for this reason as raw materials in the synthesis of intermediate products and of polymers. Over/Underlifting Agreements stipulated between partners regulate the right of each to its share in the production of a set period of time. Amounts different from the agreed ones determine temporary Over/Underlifting situations. Possible reserves 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. Production Sharing Agreement Contract in use in non OECD Countries, regulating relationships between States and oil companies with regard to the exploration and production of hydrocarbons. The mining concession is assigned to the national oil company jointly with the foreign oil company who has exclusive right to perform exploration, development and production activities and can enter agreements with other local or international entities. In this type of contract the national oil company assigns to the international contractor the task of performing exploration and production with the contractor’s equipment and financial resources. Exploration risks are borne by the contractor and production is divided into two portions: "cost oil" is used to recover costs borne by the contractor, "profit oil" is divided between contractor and national company according to variable schemes and represents the profit deriving from exploration and production. Further terms and conditions may vary from one Country to the other. Proved reserves Proved 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 know reservoirs, and under existing economic conditions. |  | 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. Reserves 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 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. Reserves can be: (i) developed reserves quantities of oil and gas anticipated to be through installed extraction equipment and infrastructure operational at the time of the reserves estimate; (ii) undeveloped reserves: oil and gas expected to be recovered from new wells, facilities and operating methods. Reserve replacement ratio Measure of the reserves produced replaced by proved reserves. Indicates the company’s ability to add new reserves through exploration and purchase of property. A rate higher than 100% indicates that more reserves were added than produced in the period. The ratio should be averaged on a three-year period in order to reduce the distortion deriving from the purchase of proved property, the revision of previous estimates, enhanced recovery, improvement in recovery rates and changes in the value of reserves – in PSAs – due to changes in international oil prices. Management also calculates this ratio by excluding the effect of the purchase of proved property in order to better assess the underlying performance of the Company’s operations. Ship or pay Clause included in natural gas transportation contracts according to which the customer for which the transportation is carried out is bound to pay for the transportation of the gas also in case the gas is not transported. Strategic Storage Volumes of natural gas required for covering lack or reduction of supplies from extra-European sources or crises in the natural gas system. Swap In the gas sector, the term is referred to a buy/sell contract between some counterparties and is generally aimed to the optimization of transport

costs and respective commitments in purchasing and supplying. Take or pay Clause included in natural gas purchase contracts according to which the purchaser is bound to pay the contractual price or a fraction of such price for a minimum quantity of the gas set in the contract also in case it is not collected by the customer. The customer has the option of collecting the gas paid and not delivered at a price equal to the residual fraction of the price set in the contract in subsequent contract years. Upstream/Downstream The term upstream refers to all hydrocarbon exploration and production activities. The term downstream includes all activities inherent to the oil sector that are downstream of exploration and production activities. Wholesale sales Domestic sales of refined products to wholesalers/distributors (mainly gasoil), public administrations and end consumers, such as industrial plants, power stations (fuel oil), airlines (jet fuel), transport companies, big buildings and households. They do not include distribution through the service station network, marine bunkering, sales to oil and petrochemical companies, importers and international organizations. |  | Workover Intervention on a well for performing significant maintenance and substitution of basic equipment for the collection and transport to the surface of liquids contained in a field.

ENI CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS / NOTES TO FINANCIAL STATEMENTS

Notes to the condensed consolidated interim financial statements
Basis of presentation

The Condensed Consolidated Interim Financial Statements of Eni Group have been prepared in accordance with IAS 34 "Interim Financial Reporting". The statements are comparable with those adopted in the Annual Report 2009 with the exception of the statement of cash flows which has been modified in order to provide an articulation of the items included in the "Net cash from operating activities" more comparable with that presented by the main integrated oil companies1.
The amounts of the comparison period have been consistently reclassified.
The Condensed Consolidated Interim Financial Statements have been prepared in accordance with the same principles of consolidation and measurement criteria as those adopted in the preparation of the Annual Report 2009 with the exception of international accounting standards effective starting from January 1, 2010 indicated in the paragraph "Accounting standards and interpretations issued by IASB/IFRIC and endorsed by EU" of Annual Report 2009. The application of these standards has had no impact on transactions performed before year 2010 with the exception of provisions of IFRIC 12 "Service concession arrangements" (hereinafter "IFRIC 12") which defines recognition and measurement criteria of public-to-private arrangements related to development, financing, operation and maintenance of infrastructure in concession. In particular, when the grantor controls the infrastructure by controlling/regulating the principal terms and conditions of services rendered, including applicable rates and retaining a residual interest in the infrastructure, the operator recognizes a right to use the infrastructure or a financial asset, according to agreements.
In particular, considering existing Group’s service concession arrangements, the application of IFRIC 12 has resulted in recognizing certain infrastructures as intangible assets; accordingly, in the comparative balance sheet as at December 31, 2009, the net carrying amount of infrastructures falling within the scope of IFRIC 12 has been reclassified from the line item "Property plant and equipment" to "Intangible assets" for an amount of euro 3,412 million. Considering the rate structure for concession services and absence of benchmark, it is not possible to reliably measure the margin for construction/upgrade activities and therefore capital expenditures are recognized as work in progress at incurred costs. The depreciation process of assets under service concession arrangements is unchanged and it is carried out considering how the entity expects to obtain future economic benefits deriving from the use and the residual value of the infrastructure, as set in reference jurisdiction.
With reference to the preparation of the Condensed Consolidated Interim Financial Statements 2010, prospectively:

• |  | starting from second quarter 2010, natural gas conversion rate from standard cubic meters into barrels of oil has been updated (6.36 barrels equal to 1,000 m3; previously 6.15 barrels equal to 1,000 m3) by collecting data on the gas heating power made considering the modified mix of Eni’s gas properties that took place in recent years. 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 rate to oil and gas joint production reservoirs. The effects of this update are not material2;
• |  | 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 impact on interim results has been euro 18 million; (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 impact on interim results has been euro 38 million.

The report includes selected explanatory notes. Income taxes were calculated based on the estimated taxable profit.
Tax payables and receivables were measured at the amount expected to be paid to/recovered from tax authorities,

_______________

(1) |  | 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" related to investments accounted for using the equity method; (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; (v) the presentation of the change in the provisions for employee benefits after the "new" item which includes the "Cash flow from working capital".
(2) |  | The effect on the production expressed in barrels of oil equivalent ("boe") of the second quarter 2010 has been of 26,000 boe/d; for the sake of comparability, also production of the first quarter of 2010 was restated resulting in an effect equal to that of the second quarter. Effects on other per-boe indicators (realization prices, costs per boe) and on depreciation are not material. Other oil companies may use different coefficients.

applying tax laws that have been enacted or substantively enacted at the end of the period and using tax rates estimated on an annual basis.
The Condensed Consolidated Interim Financial Statements at June 30, 2010, have been approved by Eni’s Board of Directors on July 28, 2010 and a limited review has been carried out by the independent auditor Reconta Ernst & Young SpA. A limited review is substantially less in scope than an audit performed in accordance with generally accepted auditing standards.

Recent accounting principles
As regards the recent accounting principles, in addition to those indicated in the Annual Report 2009, in the first half of 2010 IASB issued the document "Improvements to IFRS’s" which includes only changes to existing standards and interpretations with a technical and editorial nature.

The fair value of securities is determined using market quotations.

2 Trade and other receivables
Trade and other receivables were as follows:

(euro million) |  | Dec. 31, 2009 |  | June 30, 2010

Trade receivables |  | 14,916 |  |  | 15,493 |

|  | 4,907 |  |  | 5,920 |
|  | 20,348 |  |  | 22,285 |

Receivables were stated net of the allowance for impairment losses of euro 1,596 million (euro 1,647 million as of December 31, 2009):

(euro million) |  | Value at Dec. 31, 2009 |  | Additions |  | Deductions |  | Other changes |  | Value at June 30, 2010

Trade receivables |  | 942 |  | 126 |  | (35 | ) |  | (6 | ) |  | 1,027

|  | 1,647 |  | 136 |  | (127 | ) |  | (60 | ) |  | 1,596

The increase in trade receivables of euro 577 million mainly reflected currency translation differences arising from the translation of financial statements denominated in currencies other than euro (euro 490 million) related to the Refining & Marketing segment (euro 873 million), the Petrochemical segment (euro 326 million) and, as decrease, to the Gas & Power segment (euro 693 million).
Allowances for doubtful accounts amounted to euro 126 million and primarily related to the Gas & Power segment (euro 80 million). Other changes of euro 60 million included a reclassification of part of the allowance to the impairment provision for tangible assets of the Exploration & Production segment for euro 142 million partially offset by currency translation differences amounting to euro 100 million.
Receivables for financing operating activities of euro 808 million (euro 452 million as of December 31, 2009) included financing loans for euro 503 million to unconsolidated entities controlled by Eni, joint ventures and affiliates (euro 245 million as of December 31, 2009), a euro 281 million cash deposit to provide coverage of Eni Insurance Ltd technical reserves (euro 179 million as of December 31, 2009) and the current portion of receivables for financial leasing (euro 15 million).

Receivables for financing non-operating activities amounted to euro 64 million (euro 73 million as of December 31, 2009) and referred to cash deposits made by the Engineering & Construction segment (euro 67 million as of December 31, 2009).
Receivables with related parties are described in Note 31 – Transactions with related parties.
Because of the short-term maturity of trade receivables, the fair value approximates their carrying amount.

4 Other current assets
Other assets were as follows:

(euro million) |  | Dec. 31, 2009 |  | June 30, 2010

Fair value of non-hedging derivatives |  | 698 |  |  | 728 |
Fair value of cash flow hedge derivatives |  | 236 |  |  | 160 |
Other current assets |  | 373 |  |  | 450 |
|  | 1,307 |  |  | 1,338 |

Fair value of derivative contracts is determined using market quotations provided by primary info-providers or, if absent, appropriate valuation techniques used on the marketplace.
Fair values of non-hedging derivatives of euro 728 million (euro 698 million as of December 31, 2009) consisted of 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 hedges of euro 160 million (euro 236 million as of December 31, 2009) referred to Distrigas NV. These derivatives were designated to hedge surpluses or deficits of gas to achieve a proper balance in gas portfolio. The negative fair value for contracts expiring within June 30, 2011 is given in Note 14 – Other current liabilities; positive and negative fair value of contracts expiring beyond June 30, 2011 is given in Note 10 – Other non-current receivables and Note 18 – Other non-current liabilities. The effects of the evaluation at fair value of cash flow hedge derivatives are provided in Note 20 – Shareholders’ equity and Note 24 – Operating income (expense).

In assessing the recoverability of the carrying amount of a tangible asset or group of assets, management makes an estimate of its recoverable amount, which is represented by the higher of the asset’s fair value less costs to sell or value-in-use. Given the nature of Eni’s activities, information on fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers are in place. Therefore, the recoverability is checked by using the value in use which is calculated by discounting estimated cash flows arising from the use of the asset. The valuation is carried out for individual asset or for the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets (cash generating unit). During the first half of 2010, composition of the Group’s cash generating units has remained unchanged from the Annual Report 2009 (see the Annual Report 2009, Note 8). Cash flows have been assessed based on: (i) forward commodity prices prevailing on the market place 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; (ii) the Company’s four-year plan adopted for supporting estimations of assets’ value in use in the preparation of Annual Report 2009 and subsequent available reviews as of the preparation of this interim report related to volume and margin trends, cost/expenditure profiles, reviews of oil and natural gas reserves and other variables. Beyond the four-year plan horizon, a nominal growth rate has been used ranging from 0% to 2%.
Post-tax cash flows have been discounted at a post-tax rate which corresponds for the Exploration & Production, Refining & Marketing and Petrochemicals segments to the Company’s weighted average cost of capital, adjusted for the risks specific to each Country of activity (adjusted WACC). Adjusted WACC used for impairment purposes for the 2010 Interim Consolidated Financial Report has ranged from 9% to 13.5% and were consistent with those used for the impairment test of the Annual Report 2009. Post-tax cash flows and discount rates have been adopted as they result in an assessment that is substantially equal to a pre-tax assessment.
In the Exploration & Production segment, impairments charges were associated to oil&gas properties in the Gulf of Mexico and Egypt as a result of changes in the pricing environment for commodities and costs increases. In the Refining & Marketing and the Petrochemicals segment, impairments regarded certain health, safety and environment projects that were written-off as they related to assets completely impaired in previous reporting periods.
Currency translation differences of euro 5,462 million were primarily related to translation of entities accounts denominated in US dollar (euro 5,160 million).
Changes in the scope of consolidation of euro 700 million related to the divestment to NOC (Libya National Oil Corporation) of a 25% stake in the share capital of GreenStream BV, the company owning and managing the gas pipeline for importing to Italy natural gas produced in Libya. Following the decrease of Eni’s shareholding in the company to 50% and revised shareholders’ agreements. Eni no longer controls the company and it has therefore been excluded from consolidation as of May 1, 2010.

|  | 4,410 |  |  | 4,445 |

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 recoverable amount of the CGUs was determined by using the value in use which is calculated by discounting estimated cash flows arising from the use of the asset. Cash flows have been assessed based on: (i) forward commodity prices prevailing on the market place 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; (ii) the Company’s four-year plan adopted for supporting estimations of assets’ value in use in the preparation of Annual Report 2009 and subsequent available reviews as of the preparation of this interim report related to volume and margin trends, cost/expenditure profiles, reviews of oil and natural gas reserves and other variables. Beyond the four-year plan horizon, a nominal growth rate has been used ranging from 0% to 2%.

Post-tax cash flows have been discounted at a rate which corresponds: (i) for the Exploration & Production and Refining & Marketing and Petrochemicals segments at the Company’s weighted average cost of capital (post-tax WACC), adjusted to consider risks specific to each Country of activity. Adjusted WACC used for impairment purposes for the 2010 Interim Consolidated Financial Report has ranged from 9% to 13.5% and were consistent with those used for the impairment test of the Annual Report 2009; (ii) for the Gas & Power and Engineering & Construction segments at sector-specific WACC. For the Gas & Power segment it has been estimated on the basis of a sample of companies operating in the same segment, for the Engineering & Construction segment on the basis of market data. WACC used for impairments in the Gas & Power segment has been adjusted to take into account risks specific to each Country of activity, while WACC used for impairments in the Engineering & Construction segment has not been adjusted as most of the company assets are not permanently located in a specific Country. Adjusted WACC used for impairment purposes for the 2010 Interim Consolidated Financial Report has ranged from 7% to 8% for the Gas & Power segment and it was 8.5% for the Engineering & Construction segment. Also in this case, adjusted WACC were consistent with those used for the impairment test of the Annual Report 2009; (iii) for the regulated activities in the Italian natural gas sector, the discount rates have been assumed equal to the rates of return defined by the Italian Authority for Electricity and Gas. Post-tax cash flows and discount rates have been adopted as they result in an assessment that is substantially equal to a pre-tax assessment.
Goodwill has been allocated to the following CGUs:

Gas & Power

(euro million) |  | Dec. 31, 2009 |  | June 30, 2010

Domestic gas market |  | 766 |  |  | 766 |
Foreign gas market |  | 2,247 |  |  | 2,249 |
- of which European market |  | 2,148 |  |  | 2,148 |
Domestic natural gas transportation network |  | 305 |  |  | 305 |
Other |  | 10 |  |  | 11 |
|  | 3,328 |  |  | 3,331 |

Goodwill allocated to the domestic gas market CGU of euro 766 million primarily regarded the buy-out of non-controlling interest in Italgas SpA in 2003 through a public offering (euro 706 million). Goodwill allocated to the CGU represented by the European gas market was recognized upon acquisition of the Belgian company Distrigas NV. Such goodwill has been allocated to the CGU that is expected to benefit from the synergies of the acquisition corresponding to the European market that includes the activities of Distrigas and other European marketing activities conducted by the Gas & Power Division of Eni SpA. Key assumptions adopted for assessing the recoverable amount of both the domestic and the European gas market CGUs which exceeds their carrying amounts referred to commercial margins, forecast volumes, the discount rate and the growth rates adopted to determine the terminal value. The determination of the value-in-use is based on the four-year plan sanctioned by the Company’s top management that was used in the assessments made in the Annual Report 2009 and updated to take into account further deterioration in the economics of the gas sector in Italy and Europe caused by oversupply and rising competitive pressures leading to margin erosion and volume losses. This, notwithstanding management has revised upward its expectations for gas demand growth in 2010 and the following two-year period. The terminal value of both CGUs has been estimated through the perpetuity method of the last-year-plan considering a nominal growth rate equal to zero for Italy and 1.6% for Europe. The excess of the recoverable amount of the domestic gas market CGU over its carrying amount including the allocated portion of goodwill (headroom) would be reduced to zero under each of the following hypothesis: (i) an average decrease of 37.5% in the projected commercial margins; (ii) an average decrease of 37.5% in planned volumes; (iii) an increase of 6.5 percentage points in the discount rate; (iv) a negative real growth rate of 10.0%. The recoverable amount of the CGU domestic gas market and the relevant sensitivity analysis were calculated by using retail margins and excluding wholesale margins and margins on businesses (industrial clients, thermoelectric utilities and others). The excess of the recoverable amount of the European market CGU over its carrying amount including the allocated portion of goodwill (headroom) would be reduced to zero under each of the following hypotheses: (i) an average decrease of 28% in the projected marketing margins; (ii) an average decrease of 28% in planned volumes; (iii) an increase of 2 percentage points in the discount rate; (iv) a negative real growth rate of 2.5%.
Goodwill allocated to the domestic natural gas transportation network CGU referred to the purchase of own shares by Snam Rete Gas SpA and it is equal to the difference between the purchase cost over the carrying amount of the corresponding share of 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 changes in the assumptions adopted would cause the headroom of the CGU to be reduced to zero.

Engineering & Construction

(euro million) |  | Dec. 31, 2009 |  | June 30, 2010

Offshore constructions |  | 416 |  |  | 416 |
Onshore constructions |  | 317 |  |  | 318 |
Other |  | 16 |  |  | 16 |
|  | 749 |  |  | 750 |

Segment goodwill of euro 750 million was mainly recognized following the acquisition of Bouygues Offshore SA, now Saipem SA (euro 710 million).
The key assumptions adopted for assessing the recoverable amount of the CGUs which exceeds the carrying amount referred to operating results, the discount rate and the growth rates adopted to determine the terminal value. The assumptions, based on the four-year-plan approved by the Company’s top management and other indicators were unchanged as of the preparation of this interim report in respect of those used for the test in 2009. Therefore, the estimation of the recoverable amounts of the Offshore and Onshore construction CGUs, that exceed their carrying amounts including the relevant goodwill, and the zero setting hypothesis confirm those used in the Annual Report 2009.
The Exploration & Production and the Refining & Marketing segments tested their goodwill, yielding the following results: (i) in the Exploration & Production segment (euro 280 million of carrying amount), 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 acquisition cost that was not allocated to proved or unproved mineral interests from the business combinations of Lasmo, Burren Energy (Congo) and First Calgary; (ii) in the Refining & Marketing segment, goodwill (euro 84 million) primarily referred to the to the acquisitions in Czech Republic, Hungary and Slovakia and it was impaired in the Annual Report 2009. The recoverable amounts of these CGUs are substantially aligned to their book values including the allocated goodwill.

14 Other current liabilities
Other current liabilities were as follows:

(euro million) |  | Dec. 31, 2009 |  | June 30, 2010

Fair value of non-hedging derivatives |  | 691 |  |  | 896 |
Fair value of cash flow hedge derivatives |  | 680 |  |  | 428 |
Other liabilities |  | 485 |  |  | 470 |
|  | 1,856 |  |  | 1,794 |

Fair value of the derivative contracts is determined using market quotations provided by primary info-providers or, if absent, appropriate valuation techniques used on the marketplace.
Fair values of non-hedging derivatives of euro 896 million (euro 691 million as of December 31, 2009) consisted of 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 hedges of euro 428 million (euro 680 million as of December 31, 2009) referred to the Exploration & Production segment for euro 235 million (euro 369 million as of December 31, 2009) and to Distrigas NV for euro 193 million (euro 311 million as of December 31, 2009). Fair value related to the Exploration & Production segment referred to the fair value of the future sale agreements of the proved oil reserves with deadlines in 2011. Those derivatives were entered into to hedge exposure to variability in future cash flows deriving from the sales during the 2008-2011 period of approximately 2% of Eni’s proved reserves as of December 31, 2006, corresponding to 125.7 mmbbl, decreasing to 23.3 mmbbl as of June 30, 2010 due to transactions settled in the past year. The Distrigas NV derivatives were designated to hedge surpluses or deficits of gas to achieve a proper balance in gas portfolio. Fair value of contracts expiring by June 2011 is given in Note 4 – Other current assets; fair value of contracts expiring beyond June 30, 2011 is given in Note 10 – Other non-current assets and in Note 18 – Other non-current liabilities. The effects of the evaluation at fair value of cash flow hedge derivatives are given in Note 20 – Shareholders’ equity and in Note 24 – Other operating income (expense).

Non-current liabilities
15 Long-term debt and current maturities of long-term debt
Long-term debt including the current portion were as follows:

(euro million) |  | Dec. 31, 2009 |  | June 30, 2010

|  | Long-term portion |  | Short-term portion |  | Total |  | Long-term portion |  | Short-term portion |  | Total

Ordinary bonds |  | 10,576 |  | 1,111 |  | 11,687 |  | 11,653 |  | 539 |  | 12,192
Banks |  | 7,028 |  | 2,028 |  | 9,056 |  | 6,286 |  | 1,857 |  | 8,143
Other financial institutions |  | 460 |  | 52 |  | 512 |  | 463 |  | 54 |  | 517
|  | 18,064 |  | 3,191 |  | 21,255 |  | 18,402 |  | 2,450 |  | 20,852

Long-term debt, including the current portion of long-term debt, of euro 20,852 million (euro 21,255 million as of December 31, 2009), decreased by euro 403 million. Such decrease was due to the balance of repayments and new proceeds for euro 779 million partially offset by the negative impact of foreign currency translation differences and translation differences arising on debt taken on by euro-reporting subsidiaries denominated in foreign currency which are translated into euro at year-end exchange rates (euro 382 million).
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 the maintenance of a minimum level of rating. According to the agreements, the lack of this latter condition required new guarantees, able to be accepted by the European Investment Bank, to be found.
As of December 31, 2009 and June 30, 2010, the amount of short and long-term debt subject to restrictive covenants was euro 1,508 million and euro 1,755 million, respectively. Eni considers that non-compliance with the above mentioned covenants does not produce significant effects. Eni is in compliance with the covenants contained in the financing arrangements.

21 Guarantees, commitments and risks
Managing company’s risks
The main risks that the Company is facing and actively monitoring and managing are described in the "Risk factors and uncertainties" section of this Interim Consolidated Report as of June 30, 2010.

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:
(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);
(c) Level 3: inputs not based on observable market data.
Financial instruments measured at fair value in the balance sheet as of June 30, 2010 were classified as follows: (i) level 1, "Other financial assets held for trading or available for sale"; (ii) level 2, derivative instruments included in "Other current assets", "Other non-current assets", "Other current liabilities" and "Other non-current liabilities". During the first half of 2010 no transfers were done between the different hierarchy levels of fair value. More information about the amount of financial instruments valued at fair value are provided in Note 1 – Other financial assets held for trading or available for sale, Note 4 – Other current assets, Note 10 – Other non-current assets, Note 14 – Other current liabilities and Note 18 – Other non-current liabilities.

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.

(ii) Investigation of the quality of ground water 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 ground water in the area of the refinery. Eni is charged of having breached environmental rules concerning the pollution of water and soil and of illegal disposal of liquid and solid waste materials. 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 the renewal of the debate phase. In the said phase were examined indictment and defense witnesses. Subsequently it was examined the first technical appraiser of the defense. 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 of a 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.

(iii) 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 death of four workers deputed 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 sulphur 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 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 sentenced that both the above mentioned persons and the three companies were guilty of the charged responsibilities. 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 sulphur. 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 sulphur. On April 14, 2010 the judge for preliminary hearings notified to 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 the closing of the investigation that objected the manslaughter, grievous bodily harm and illegal disposal of waste materials. A number of defendants filled defensive memoranda. The Public Prosecutor has removed three defendants and transmitted evidence to the Judge for preliminary investigations requesting to dismiss the proceeding.
The judgment is pending.

(iv) 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 it was notified 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 on 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 basing 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.

1.2 Civil and Administrative proceedings

(i) 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 in order Syndial is condemned to compensate for the 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 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 favourable 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 of 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 of 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

- 110 -

ENI CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS / NOTES TO FINANCIAL STATEMENTS

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. In order to arrange for a possible resolution of all environmental claims, in 2008 Eni’s subsidiary Syndial took charge of the management of the clean-up activities and on December 5, 2008 presented a new clean-up project. As for the approval procedure of the abovementioned 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 cleanup 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. The claims made in this first instance are substantially absorbed in the two subsequent proceedings.

(ii) Summon for alleged environmental damage caused by DDT pollution in the Lake Maggiore - Prosecuting body: Ministry of 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 of 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 abovementioned technical legal advice, in concert with external consultants on accounting principles. In July 2009, Eni’s subsidiary Syndial filed an appeal against the abovementioned sentence, also requesting suspension of the sentence effectiveness. The Ministry of 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 of the Environment related to the determination of the quantification criteria for the monetary compensation of the environmental damage pursuant to the abovementioned 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 of 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.
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 of 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

- 111 -

ENI CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS / NOTES TO FINANCIAL STATEMENTS

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 abovementioned prescriptions that have been prescribed are the object of the Company opposition in the abovementioned proceeding. In case Syndial should be found guilty, it would incur remediation and cleanup 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.

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

2.1 Antitrust

ENI SPA
(i) 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. The European Commission submitted those remedies to a market test. According to the results of the market test, the Commission may issue a decision pursuant to Article 9 of Council Regulation No. 1/2003, making the remedies mandatory thus excluding the imposition of any fines upon Eni. In case the Commission, after the evaluation of the results of the market test, resolves to reject Eni’s remedies, or the Company decides to withdraw those remedies for any reasons, the ordinary antitrust proceeding would resume and in this eventuality an adverse conclusion cannot be excluded, thus resulting in a sentence of conviction including a fine and possibly structural remedies during the course of 2010. Eni would in any event be entitled to file an appeal for the annulment of such a sentence before the EC Courts.

(ii) 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 AGCM 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. Following the market test ended on April 26, 2010, the Authority should make a final decision on the proposed commitments, making them mandatory and thus resolving the proceeding without the ascertainment of the illicit behavior and consequently without imposition of any fines. In case the Authority, after the performance of the market test, resolves to reject the proposed remedies, the ordinary antitrust proceeding would resume and in this eventuality an adverse conclusion could result in an appeal with an Administrative Court. The deadline for the finalization of the preliminary investigation against Eni and Italgas has been scheduled for October 31, 2010.

(iii) 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.

2.2 Regulation

(i) Preliminary investigation of the Authority for Electricity and Gas on the billing of the tariff balance to finale 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. The preliminary investigation should be finalized within a 100-day term from the communication of the proceeding to the company and further 45 days for the final decision.

3. Court Inquiries

(i) TSKJ Consortium Investigations by US, 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 Halliburton/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 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 US Securities and Exchange Commission (SEC), the US Department of Justice (DOJ), and other authorities, including the Public Prosecutor’s office of Milan, have commenced investigations about alleged improper payments made by the TSKJ Consortium to certain Nigerian public officials.
The proceedings in the US: beginning in June 2004, Eni and Saipem/Snamprogetti voluntarily provided information in response to requests by the SEC and the DOJ in connection with the investigations. In February 2009, KBR and its former parent company, Halliburton, announced that they had reached a settlement with the SEC and the DOJ with respect to the TSKJ matter as well as other unspecified matters. KBR/Halliburton pleaded guilty to Foreign Corrupt Practices Act (FCPA) charges, for the conduct stemming from their participation in TSKJ, and they have agreed to pay a criminal fine of $402 million to the DOJ and a civil penalty of $177 million to the SEC.
As announced in a press release on June 28, 2010, also the French company Technip has reached final agreements with US authorities entailing the payment of $338 million and the adoption of a number of measures, including an external monitoring, for a period of two years to assess Technip’s internal control system. Also KBR was charged with undergoing an external monitoring for a period of three years.
As to Snamprogetti and Eni, discussions with the US authorities have intensified in the last months in order to achieve a global resolution of the matter. Consequently the company recorded a loss provision amounting to euro 250 million in its 2009 Consolidated Financial Statement also considering the contractual obligations assumed by Eni to indemnify Saipem as part of the divestment of Snamprogetti. On July 7, 2010, Snamprogetti Netherlands BV signed a deferred prosecution agreement with the US Department of Justice whereby the department filed a deed which could lead to starting a criminal proceeding against Snamprogetti Netherlands BV for having violated certain rules of the FCPA. Snamprogetti Netherlands BV was also fined by an amount of $240 million. In case Snamprogetti Netherlands BV thoroughly fulfils the obligations set by the agreement, the Department will refrain from continuing the criminal proceeding once a two-year frame has elapsed (that can be increased up to three years). Eni and Saipem assumed the role of guaranteeing the effective fulfillment of the obligations agreed upon by Snamprogetti Netherlands BV with the US Department of Justice. The relevant cash settlement occurred in July.
In addition Snamprogetti Netherlands BV and the parent company Eni being an entity listed on the NYSE reached an agreement with the US SEC whereby the two Companies agreed to be subpoenaed and be judged having allegedly violated certain rules of the Security and Exchange Act of 1934 without pleading guilty. They both agreed to pay jointly and severally an amount of $125 million to the US SEC in relation to the disgorgement of profit. The relevant cash settlement occurred in July.
Eni, Saipem and Snamprogetti Netherlands BV have actively cooperated in the investigation conducted by the US Authorities and have also implemented significant improvements to their respective internal control systems, including procedures against

corruption. The global transactions arranged with the US Authorities do not foresee imposition of any external independent monitoring on the internal control system which is a measure frequently imposed in cases such as this one. Eni and its subsidiaries are engaged in continuously improving and upgrading their internal control systems.
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. On July 17, 2009, the date on which a search and attachment warrant was served on Saipem/Snamprogetti, the Public Prosecutor’s office of Milan indicated to the company that it is investigating one or more people, including at least one former manager of Snamprogetti; previously, as far as the company knew, none of its employees or former employees was under formal investigation. 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 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 Corporation 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. Since April 23, 2009, with regard to investigations on the TSKJ matter the Company’s Board of Directors has timely recalled the analysis of the existing internal procedures against corruption, in order to implement any upgrading to be possibly needed, and to continue the cooperation with the relevant authorities and also resolved to promote all legal measures for protecting the Company’s interests and reputation, in the event the responsibility of its employees or collaborators is verified. The jury room of September 22, 2009 was postponed to the hearing of October 21, 2009 when 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 Preliminary Investigation. The hearing for the review of the appeal, scheduled initially for January 20, 2010 was moved up, through a measure communicated to the defense on January 12, 2010, on January 19, 2010 when 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 abovementioned decision of the Judge of Re-examination. The hearing in the Third Instance Court scheduled on May 20, 2010 has been postponed due a lack in the formal communication to one of the defendants.
At the same time on February 11, 2010 the Public Prosecutor of Milan requested, according to Article 248 of Penal Code the collection of documentation and information related to companies participated by Eni SpA and Saipem SpA (former Snamprogetti SpA) involved in the Bonny Island project.

(ii) 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 Courts 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 14 Eni employees, also including former employees, are under investigation. The exceptions filed in the notice include:

Finance income (expense) related to net borrowings |  |  |  |  |  |
Interest due to banks and other financial institutions |  | (205 | ) |  | (97 | )

Negative exchange differences of euro 3,482 million included currency adjustment amounting to euro 47 million to the loss provision accrued in the Annual Report 2009 to take account of the TSKJ proceeding.
Derivative financial instruments consisted of the following:

(euro million) |  | First Half 2009 |  | First Half 2010

Derivatives on exchange rate |  | 69 |  |  | (249 | )
Derivatives on securities |  | 3 |  |  | 5 |
|  | 48 |  |  | (331 | )

Net loss from derivatives of euro 331 million (net gain of euro 48 million in the first half of 2009) 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 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.
