San Donato Milanese, July 26, 2007 - Eni, the international oil and gas company today announces its group results for the second quarter and first half of 2007 (unaudited).

Paolo Scaroni, Chief Executive Officer, commented:

"Eni delivered a set of solid results in the first half of 2007 despite the adverse impact of the euro's appreciation against the dollar and lower gas sales due to exceptionally mild weather. We have been expanding our portfolio and I am confident that 2007 will be another excellent year for Eni. This confidence underpins my proposal to Eni's Board to pay an interim dividend of euro 0.60 per share."

Financial highlights

Second Quarter of 2007

| - | Adjusted operating profit
was euro 4.20 billion, down 17% from the second quarter
of 2006. Results in the Exploration & Production
division, were impacted by a 7.3% appreciation of the
euro against the dollar, lower sold production volumes
and higher exploratory expenses, while results in the Gas
& Power division were affected by declining selling
margins and the impact of mild weather on sales volumes,
particularly in April. |
| --- | --- |
| - | Adjusted net profit was down
10.6% to euro 2.22 billion, mainly as a result of the
reduced operating profit, partly offset by a two
percentage point reduction recorded in the Group tax-rate
on an adjusted basis (from 50.4% to 48.3%). |
| - | Capital expenditures for the
quarter were up 30.9% from a year ago to euro 2.24
billion. Major expenditures related to the development of
oil and gas reserves, exploratory projects and the
upgrading of international and domestic gas
transportation infrastructure and refineries. |
| - | Net borrowings amounting to
euro 9.12 billion as of June 30, 2006 increased by euro
5.27 billion in the quarter due to cash outflows for
capital expenditures (euro 2.24 billion), the acquisition
of investments as part of a bid procedure for ex-Yukos
assets (euro 3.73 billion), the acquisition of upstream
properties onshore Congo (approximately euro 1 billion)
and the payment of the balance of 2006 dividend to
shareholders (euro 2.38 billion). These outflows were
partly absorbed by net cash provided by operating
activities (euro 4.14 billion). |

First Half of 2007

| - | Adjusted operating profit
for the first half was euro 9.45 billion, down 10.7% from
a year ago. A weaker operating performance reported by
the Exploration & Production division was partly
offset by the improved operating performance in all of
Eni’s downstream businesses and the Engineering
& Construction division. |
| --- | --- |
| - | Adjusted net profit was down
9.9% to euro 4.90 billion, mainly as a result of the
reduced operating profit, which was partly offset by a
single percentage point reduction recorded in the Group
tax-rate on an adjusted basis (from 48.4% to 47.4%). |
| - | Net borrowing at period-end
increased by euro 2.35 billion to euro 9.12 billion, as
compared to December 31, 2006. Main cash outflows for the
period were: euro 4.26 billion for capital expenditures,
euro 4.8 billion for the acquisition of investments and
assets, euro 2.38 billion for dividend payment and euro
339 million for the repurchase of own shares. These
outflows were partly absorbed by net cash provided by
operating activities coming in at euro 9.7 billion. |
| - | Return on Average Capital
Employed (ROACE) 2 calculated on an adjusted
basis for the twelve-month period ending June 30, 2007
was 21.4% (23.5% for the twelve-month period ending June
30, 2006). |
| – | Ratio of net borrowings to
shareholders’ equity including minority interest
– leverage 2 – decreased to 0.22 from
0.16 at the end of 2006. |

Interim dividend for 2007

In light of the financial results achieved for the first half of 2007, the CEO will propose the distribution of an interim dividend for the fiscal year 2007 of euro 0.60 per share (euro 0.60 per share in 2006) to the Board of Directors at a meeting to approve first half accounts on September 20, 2007. The interim dividend is payable on October 25, 2007 to shareholders on the register on October 22, 2007.

Second Quarter of 2007

| - | Oil and natural gas
production for the second quarter averaged 1.736 mmboe/d,
a decrease of 0.7% compared with the second quarter of
2006 due mainly to disruptions in Nigeria owing to
continuing social unrest. Excluding this issue,
production was in line with the second quarter of 2006.
Growth was achieved in Libya, Kazakhstan and the Gulf of
Mexico, offsetting mature field declines, particularly in
Italy and the United Kingdom, and facility outages in
Norway. |
| --- | --- |
| - | Eni’s worldwide natural
gas sales were marginally lower at 20.43 bcm (down 0.1%)
due to unusually mild weather conditions, particularly in
April. Higher volumes were achieved in certain target
European markets (particularly in Spain and Turkey) and
in Italy driven by growth in the power generation sector
and higher sales to wholesalers reflecting increased
production volumes from Eni’s Libyan gas fields. Lower sales were recorded to Italian importers. |
| - | The trading environment was
affected by lower oil prices with Brent crude prices
averaging $68.76 per barrel (down 1.2%; down 8% if
expressed in euro) compared to the second quarter 2006,
and the appreciation of the euro over the dollar (up
7.3%). Unfavorable trends were also recorded in energy
parameters used in determining purchase and selling
prices of natural gas. By contrast, refining margins on
the Brent crude marker increased sharply (up 19.6%; up
11.5% if expressed in euro). It is worth noting that the
narrowing of price differentials between light and heavy
crude qualities, while capping the upside on Eni’s
realized refining margins, helped upstream crude
realizations which improved somewhat from 2006 as opposed
to the trend registered in the Brent crude marker. |

First Half of 2007

| - | Oil and natural gas
production for the first half averaged 1.735 mmboe/d, a
decrease of 2.9% compared with the first half of 2006. In
addition to Nigerian events, production performance for
the period was impacted by the loss of production at the
Venezuelan Dación oilfield (down 31 kbbl/d) as a
consequence of the unilateral cancellation of the service
agreement for the field exploitation by the Venezuelan
State Oil Company PDVSA effective April 1, 2006.When
factoring in these two events, production was virtually
flat from the first half of 2006. |
| --- | --- |
| - | Eni’s worldwide natural
gas sales were down 6% to 48.57 bcm due to lower European
gas demand owing to unusually mild winter weather. |
| - | The trading environment was
affected by lower oil prices with Brent crude prices
averaging $63.26 per barrel (down 3.7%; down 10.9% if
expressed in euro) compared to the first half of 2006,
and the appreciation of the euro over the dollar (up
8.1%). These negatives were partially offset by increased
refining margins on the Brent crude marker (up 14.2%; up
5.6% if expressed in euro) and higher selling margins on
petrochemical products. Overall, the first half trading
environment had no material impact on natural gas selling
margins. |

Portfolio developments

| - | As part of the strategic
alliance with Gazprom, Eni signed a Memorandum of
Understanding for the construction of the South Stream
pipeline system which is expected to connect Russia to
the European Union across the Black Sea. Implementation
of this agreement will enable Eni to extract further
value from its recent acquisition of ex-Yukos gas assets
and represent a decisive step towards strengthening the
security of energy supply for Europe. |
| --- | --- |
| - | Eni signed an agreement for
the acquisition of a significant stake in Altergaz, the
main independent operator in the French gas market. Eni
is expected to obtain an ownership interest of 27.8% by
direct purchase and subscribing a reserved share capital
increase, and to jointly control the company. Through
this partnership Eni will supply Altergaz with
significant volumes of gas up to 1.3 bcm per year, over a
period of 10 years, thus underpinning Eni’s
international expansion in the marketing of gas and
strengthening its leadership in the European gas market. |
| - | Eni signed a gas sale
agreement relating to the Karachaganak oil and gas field:
as part of Phase 3 of the field development project,
Karachaganak Petroleum Operating BV (KPO), the consortium
operating this field cooperated by Eni with a 32.5%
working interest, and KazRosGaz, a joint company
established by KazMunaiGaz and Gazprom, signed an
agreement envisaging delivery of approximately 16 bcm/y
of raw gas from field production to the Orenburg
processing plant in Russia, starting in 2012. This
agreement is subject to approval by the boards of the two
partners. |
| - | Eni purchased a 16.11% stake
in the Czech Refining Company from ConocoPhillips,
increasing Eni’s ownership interest to 32.4%. This
transaction is expected to be finalized in the third
quarter of 2007 and to double Eni’s share of
refining capacity to 2.6 mmtonnes per year. This
transaction is intended to support the expansion of
Eni’s refining and marketing operations in
Central-Eastern Europe. |
| - | Eni signed an agreement with
Auchan for the marketing of jointly-branded fuels in
Auchan chain-stores in Italy. This initiative supports
Eni’s aim of enhancing its retail network leveraging
on ongoing trends in the marketing of fuels. |
| - | Eni signed a Memorandum of
Understanding with the Venezuelan national company PDVSA
for the transfer of development activities at the
Corocoro field in Venezuela to the new contractual regime
of "empresa mixta". Eni will retain its 26%
stake in this project. The agreement will be finalized by
the third quarter of 2007. |
| - | Eni finalized the purchases
of proved and unproved oil and gas properties in the Gulf
of Mexico from the US company Dominion Resources and
onshore in Congo from the French company’s Maurel
& Prom, early in July and by end of May 2007,
respectively. The assets purchased in the Gulf of Mexico
will add an expected 75 kboe/d from the third quarter
2007 to Eni’s oil and gas production; Congolese
assets are already yielding 17 kbbl/d net to Eni. |
| - | Hydrocarbon reserves were
discovered off the coast of Indonesia (Tulip), in
addition to a successful appraisal activity on the Aster
field (both operated). Two gas discoveries were made
onshore Pakistan (Tajal and Latif) near producing areas
and facilities, in addition to an extension of a gas
producing field (Kadanwari). Other discoveries were made
off the coast of Angola, Congo, Nigeria, the Gulf of
Mexico and the Alaska. |

Outlook for 2007 The outlook for Eni in 2007 remains positive, with key business trends for the year as follows:

| - | Production of liquids and
natural gas is forecast to remain stable as compared
to the previous year (actual oil and gas production
averaged 1.77 mmboe/d in 2006) under the assumption of
full-year Brent crude oil prices at $55 per barrel.
Production decreases due to escalating social unrest in
Nigeria and the loss of the Dación oilfield in Venezuela
and mature field production declines are expected to be
offset by the contribution from properties acquired in
the Gulf of Mexico and Congo as well as ongoing build-up
in gas production in Libya. |
| --- | --- |
| - | Sales volumes of natural
gas worldwide are expected to increase by a small
amount from the previous year (actual sales volumes in
2006 were 97.48 bcm). Growth is expected to be achieved
in European target markets both in terms of market share
and volumes gains, mainly in Spain, France and
Germany/Austria markets. Sales volumes in Italy are
expected to be flat as a result of a planned recovery in
the second half of 2007, with the main increases expected
in the residential segment as a result of ongoing
marketing initiatives. |
| - | Sales volumes of
electricity are expected to increase by approximately
4% from 2006 (actual volumes in 2006 were 31.03 TWh), due
to an expected increase in traded volumes. |

Table of Contents

| - | Refining throughputs are
forecast to remain almost unchanged from 2006 (actual
throughputs in 2006 were 38.04 mmtonnes), reflecting
higher volume performance expected at the Livorno, Gela
and Sannazzaro refineries; on the negative side, a
processing contract expired late in 2006 at the Priolo
refinery owned by a third party affecting throughputs for
the full 2007. |
| --- | --- |
| - | Retail sales of refined
products are expected to marginally increase from
2006 (actual volumes sold in 2006 were 12.48 mmtonnes),
driven by increased sales in Europe as a result of a
greater number of service stations as a result of
acquisitions in target markets. Marketing initiatives
mean that sales in the Italian market are expected to
remain unchanged despite a decline in domestic
consumption. |

Eni’s capital expenditures on exploration and capital projects in 2007 is expected to amount to approximately euro 10.6 billion, including expenditures for developing acquired upstream assets, representing a 35% increase on 2006. Approximately 86%of this capital expenditure programme is expected to be deployed in the Exploration & Production, Gas & Power and Refining & Marketing divisions. Furthermore, acquisitions of assets and interests amounting to euro 9.4 billion are forecast for 2007, of which euro 4.8 billion related to deals finalized in the first half of the year (namely the acquisition of ex-Yukos assets and proved and unproved oil properties onshore Congo), with the residual euro 4.6 billion relating to transactions which will be accounted in investing cash flows for the second half of the year (namely the purchase of upstream assets in the Gulf of Mexico, and refining and marketing assets in Central-Eastern Europe). If Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni, net cash outflows used in investing activities will decrease to euro 16.5 billion. On the basis of the expected cash outflows for planned capital expenditures and acquisitions, and shareholders remuneration, while assuming a $55/barrel scenario for the Brent crude oil, Eni foresees its gearing to settle in the low or high end of the 0.3/0.4 range by the end of the year, depending on the exercise of the above mentioned call options by Gazprom.

Second Quarter of 2007

Group results Eni’s net profit for the second quarter of 2007 was euro 2,267 million, down euro 34 million from the second quarter of 2006, or 1.5%, due mainly to a lower operating performance down by euro 729 million, or 14.7%, as a result of a decline in the Exploration & Production and Gas & Power divisions. This reduction in operating profit was offset in part by a euro 558 million decrease in income taxes reflecting lower profit before taxes and a 5 percentage point decline in the Group tax rate (from 53.0 to 48.1%) as a result of a lower share of profit generated by the Exploration & Production division.

Eni’s adjusted net profit amounted to euro 2,220 million, down 10.6% from the second quarter 2006. Adjusted net profit is arrived at by excluding an inventory holding gain of euro 207 million and special charges of euro 160 million net, resulting in an immaterial adjustment to net profit (down euro 47 million).

Results by division

The decline in the Group adjusted net profit was a result of:

| - | The reduction of adjusted
net profit reported by the Exploration &
Production division (down euro 277 million, or 14.4%)
due to a weaker operating performance (down euro 739
million, or 17.5%), which was adversely impacted by the
appreciation of the euro over the dollar (7.3%), a
decline in production sold (down 2.7 mmboe) and higher
exploration expenses (euro 187 million); |
| --- | --- |
| - | The reduction of adjusted
net profit registered in the Gas & Power division
(down euro 220 million, or 34.5%) due to a weaker
operating performance (down euro 272 million, or 34.4%)
which was adversely impacted by lower natural gas selling
margins affected by an unfavorable trading environment
and the impact of mild weather on sales volumes. These
negative factors were offset in part by positive
regulatory developments in Italy due to recently enacted
measures by the Italian Authority for Electricity and Gas
regarding the indexation of tariffs in the residential
segment. Divisional results were also negatively impacted
by lower results recorded by equity-accounted entities. |

These declines in the adjusted net profit were partly offset by a higher adjusted net profit reported in the divisions:

| - | Engineering &
Construction (up euro 94 million, or 144.6%),
reflecting an improved operating performance (up euro 70
million) against the backdrop of favorable demand trends
in oilfield services; |
| --- | --- |
| - | Petrochemicals (up
euro 38 million, or 292.3%), due to an improved operating
performance (up euro 62 million) reflecting a recovery in
product selling margins and the circumstance that results
for the second quarter 2006 were materially affected by
an accident that occurred at the Priolo refinery
resulting in outages at several of Eni’s
petrochemical plants. |

First Half of 2007

Group results Eni’s net profit for the first half of 2007 was euro 4,855 million, down euro 420 million from the first half of 2006, or 8%, due primarily to a lower operating performance (down euro 1,219 million, or 11.6%) as a result of a decline mainly in the Exploration & Production division, partially offset by the a positive performance delivered by Eni's downstream and the Engineering & Construction businesses. This reduction in operating profit was offset in part by lower income taxes (down by euro 874 million) owing to lower profit before taxes and a 2 percentage point decline in the Group tax rate (from 49.7 to 47.5%).

Eni’s adjusted net profit amounted to euro 4,900 million, down 9.9% from the first half of 2006. Adjusted net profit is arrived at by excluding an inventory holding loss of euro 110 million and special charges of euro 155 million net, resulting in an immaterial adjustment to net profit (up euro 45 million).

Return on Average Capital Employed (ROACE) calculated on an adjusted basis for the twelve-month period ending June 30, 2007 was 21.4% (23.5% for the twelve-month period ending June 30, 2006). Assuming Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni as of June 30, 2007, the Group ROACE would stand at 22.1%.

Results by division The decline in the Group adjusted net profit resulted from to the reduction of adjusted net profit recorded in the Exploration & Production division (down euro 963 million, or 24%), due to a weaker operating performance (down euro 1,858 million, or 21.9%) which was adversely impacted by the appreciation of the euro over the dollar (8.1%), a decline in production sold (down 12.2 mmboe), higher exploration expenses, and lower realizations in dollars (down 2.1%). Performance in this segment was also negatively affected by the two percentage point increase in the adjusted tax rate (from 52.8% to 54.5%) due to changes in the fiscal regime of the United Kingdom and Algeria enacted in the second half of 2006. These declines in the adjusted net profit were partly offset by a higher adjusted net profit reported in the divisions:

| - | Engineering &
Construction (up euro 152 million, or 100%),
reflecting an improved operating performance (up euro 168
million) against the backdrop of favorable demand trends
in oilfield services. |
| --- | --- |
| - | Petrochemicals (up
euro 101 million, or 348.3%), due to an improved
operating performance (up euro 161 million), reflecting a
recovery in product selling margins and the impact of the
accident that occurred at the Priolo refinery on the
results for the first half of 2006. |
| - | Gas & Power (up
euro 60 million, or 4%), due to a better operating
performance (up euro 208 million, or 10.4%) reflecting
essentially positive developments in the regulatory
framework in Italy and because certain purchase charges
were incurred in the first quarter of 2006 due to the
climatic emergency in the 2005-2006 winter. These
positive factors were offset in part by the impact of
unusually mild weather conditions affecting natural gas
by consolidated subsidiaries (down 2.8 bcm, or 6.2%).
This also resulted in a weakened sales mix, offset in
part by volume increases in target markets in Europe.
Divisional results were also negatively impacted by
weaker equity-accounted entity results. |

Net borrowings and cash flow Net borrowings as of June 30, 2007 amounted to euro 9,122 million, increased by euro 2,355 million from December 31, 2006. Net cash provided by operating activities totalled euro 9,703 million. The main cash outflows related to: (i) capital expenditures totalling euro 4,257 million; (ii) the purchase of interests in OAO Gazprom Neft and three Russian companies engaged in developing natural gas following finalization of a bid procedure for ex-Yukos assets (euro 3,729 million); (iii) the purchase of oil producing assets onshore Congo (approximately euro 1 billion); (iv) dividend payments (euro 2,611 million, of which euro 2,384 million concerning the balance of the 2006 dividend by the parent company Eni SpA); (v) the repurchase of Eni’s own shares for euro 339 million.

Leverage The ratio of net borrowings to shareholders’ equity including minority interest increased to 0.22 from 0.16 at December 31, 2006.

Repurchase of own shares From January 1 to June 30, 2007, a total of 13.83 million own shares were purchased by the company for a total amount of euro 339 million (representing an average cost of euro 24.504 per share). Since the inception of the share buy-back programme (September 1, 2000), Eni has repurchased 349 million shares, equal to 8.71% of outstanding capital stock, at a total cost of euro 5,851 million (representing an average cost of euro 16.774 per share).

Capital expenditures Capital expenditures in the first half of 2007 amounted to euro 4,257 million (euro 3,054 million in the first half 2006) and related mainly to:

| - | Development activities (euro
1,965 million) deployed mainly in Kazakhstan, Egypt,
Italy, Angola and Congo and exploration projects (euro
748 million) of which 92% was spent outside Italy,
primarily in Egypt, the Gulf of Mexico, Norway, Nigeria,
and Indonesia. In Italy exploration activity related
primarily to projects off the coast of Sicily; |
| --- | --- |
| - | Development and upgrading of
Eni’s natural gas transport and distribution
networks in Italy (euro 329 million) and upgrading of
natural gas import pipelines to Italy (euro 93 million); |
| - | Ongoing construction of
combined cycle power plants (euro 88 million); |
| - | Projects aimed at improving
the flexibility and yields of refineries, including the
construction of a new hydrocracking unit at the
Sannazzaro refinery (euro 214 million), building of new
service stations and upgrading of existing ones (euro 85
million); |
| - | Upgrading of the fleet used

Eni’s Stock option plan for the 2006-2008 period: Eni’s Board of Directors approved grant for 2007 At a meeting on July 27, 2006 following Eni’s Shareholder’s meeting resolution on May 25, 2006, Eni’s Board of Directors defined the terms and conditions for the 2007 grants based on Eni’s 2006-2008 Stock Option Plan. Necessary regulatory approvals were also given. Following the proposal by the Compensation Committee – Eni’s Board of Directors decided to grant a maximum of 8 million rights (options) for the purchase of a corresponding number of Eni shares held in treasury. Options will be awarded to 330 managers of the parent company Eni SpA and its non-listed subsidiaries who hold top positions and roles of significant responsibility for achieving profitability or strategic targets. Grantees will be entitled to the right to purchase Eni shares after three years from the date of the grant at a price corresponding to the higher of:

| - | The arithmetic average of
official prices recorded on the Italian stock exchange in
the month preceding the date of the grant, and |
| --- | --- |
| - | The average purchase cost of
shares held in treasury as of the day prior to the grant
(strike price). |

The number of options that each grantee will be able to exercise will be established by the Board of Directors before March 2010. This number may vary from zero to 100% of the options granted according to the total shareholder return of Eni shares as compared to that of the other six major international oil companies by market capitalization as actual results for three-year period 2007-2009. Information on this incentive scheme will be provided to Italian market and securities authorities before September 15, 2007 in accordance with Italian listing standard.

Demerger of EniPower The Board of Directors decided EniPower (100% Eni SpA) to be partly demerged from the parent company Eni SpA according the scheme approved by the same Board on June 7, 2007.

Oil and gas realizations in dollars were stable due to higher liquid realizations which benefited from narrowing differentials between heavy and light crude recorded in the quarter, partly offset by lower gas realizations. Adjusted net profit was euro 1,647 million, down euro 277 million from the second quarter of 2006, primarily due to a weaker operating performance.

The adjusted operating profit for the first half of 2007 was euro 6,615 million, down euro 1,858 million, or 21.9%, due to the impact of the appreciation of the euro versus the dollar, lower production sold (down 12.2 mmboe, or 3.9%) and higher expenses incurred in connection with exploration activity (euro 376 million; euro 426 million on a constant exchange rate basis). Results were also affected by lower realizations in dollars (down 2.1%) and higher production costs and amortization/depreciation charges.

Adjusted net profit of the first half of 2007 was euro 3,056 million, down euro 963 million (down 24%) due to a weaker operating performance and a higher tax rate (increased from 52.8% to 54.5%) due to changes in the fiscal regimes of the United Kingdom and Algeria enacted in the second half of 2006.

Special charges excluded by the adjusted operating profit of euro 65 million in the second quarter and euro 65 million in the first half concerned mainly impairment of assets.

Oil and natural gas production in the second quarter of 2007 averaged 1,736 kboe/d, a decrease of 12 kboe/d compared to the same period last year (down 0.7%). This reduction was due primarily to the negative impact of disruptions resulting from continuing social unrest in Nigeria. Factoring in this effect, oil and natural gas production levels were in line with the first quarter 2006. Production increases were achieved mainly in Libya, Kazakhstan and the Gulf of Mexico, in addition to the effect of recently acquired oil assets in Congo, which offset mature field declines in Italy and in the North Sea, with the latter being affected also by facility outages. 88% of oil and natural gas production was produced outside Italy (86% in the second quarter of 2006).

Daily production of oil and condensates (1,026 kbbl) decreased by 30 kbbl, or 2.8% from the second quarter of 2006. Production decreases were reported mainly in Nigeria, the United Kingdom and Norway due to the above mentioned impacts. Significant increases were registered in: (i) Kazakhstan, as result of higher performance at the Karachaganak field; (ii) the United States, as result of the full recovery of certain offshore production facilities damaged by hurricanes in the second half of 2005; (iii) Libya, due to production rump-up at the Bahr Essalam field.

Daily production of natural gas for the second quarter (4,082 mmcf/d) increased by 108 mmcf/d, or 2.7%, mainly at the Bahr Essalam field offshore Libya, in Norway as a result of production growth an the Aasgard and Kristin fields and in Nigeria due to the build up of supplies to the Bonny LNG plant. Gas production in Italy decreased due to mature field declines.

Oil and natural gas production for the first half of 2007 averaged 1,735 kboe/d, a decrease of 52 kboe/d compared to the same period last year (down 2.9%). In addition to events in Nigeria, production performance for the period was impacted by the loss of production at the Venezuelan Dación oilfield (down 31 kbbl/d) as a consequence of the unilateral cancellation of the service agreement for the field exploitation by the Venezuelan State Oil Company PDVSA effective April 1, 2006. When factoring in these two events, production was barely flat from the first half of 2006. Production increases were achieved mainly in Libya, Kazakhstan and the Gulf of Mexico offsetting mature field declines in Italy and in the North Sea, with the latter being affected also by facility outages. Oil and natural gas production share outside Italy was 87% (86% in the first half of 2006).

Daily production of oil and condensates (1,028 kbbl) decreased by 71 kbbl/d, or 6.5%, from the first half of 2006. Production decreases were reported mainly in Venezuela, Nigeria and the North Sea. Significant increases were registered in Kazakhstan and the United States.

Daily production of natural gas for the first half of 2007 (4,063 mmcf/d) increased by 113 mmcf/d, or 2.7%, mainly as a result of the build-up of the Bahr Essalam field off the coast of Libya. Gas production in Italy decreased due to mature field declines.

Adjusted operating profit for the second quarter of 2007 was euro 519 million, representing a decline of euro 272 million, or 34.4%. This was due mainly to a decline in gas selling margins due mainly to an unfavorable trading environment and the impact of mild weather on sales volumes.

This was partly offset by the positive impact of favorable developments with Italy’s regulatory framework.

This reflected the enactment of Resolution No. 79/2007 by the Authority for Electricity and Gas implementing a more favorable indexation mechanism of the raw material cost component in supplies to residential and commercial users compared to what was in force in the first half of 2006 as established by Resolution No. 248/2004.

Adjusted net profit of the second quarter of 2007 decreased by euro 220 million to euro 418 million, down 34.5%, due to lower adjusted operating profit and a lower performance recorded by certain affiliates accounted for under the equity method of accounting.

Adjusted operating profit for the first half of 2007 increased by euro 208 million to euro 2,202 million, up 10.4%, notwithstanding the occurrence of unusually mild winter weather conditions resulting in lower volumes sold of natural gas by consolidated subsidiaries (down 2.8 bcm, or 6.2%). Despite this negative impact, divisional results were driven by:

| - | The impact of favorable
developments in the Italian regulatory framework. This
reflected the enactment of Resolution No. 79/2007 by the
Authority for Electricity and Gas as discussed above; |
| --- | --- |
| - | Supply charges incurred in
the same period last year caused by a climatic emergency
for the winter time 2005-2006. |

The favorable trends recorded in the first quarter reversed in the second quarter as a result of the trading environment determining gas selling margins, resulting in an immaterial impact for the first half.

Net adjusted profit for the first half 2007 was euro 1,577 million, representing an increase of euro 60 million over the first half of 2006, up 4%. This reflected higher adjusted operating profit, offset in part by weaker performance in certain affiliates accounted for under the equity method of accounting.

In the second quarter of 2007, natural gas sales of 20.43 bcm, including own consumption and sales by affiliates and upstream sales in Europe were marginally lower compared with the same period a year ago due to mild weather, particularly in April (down 0.02 bcm). The main decrease was recorded in supplies to Italian importers (down 1.18 bcm) due to lower take-or-pay contract off-takes reflecting outages at certain power generation plants. Also volumes produced in the North Sea declined by 0.21 bcm. Main increases in sales were recorded in:

| - | Target markets in the Rest
of Europe (up 1.08 bcm), particularly Turkey (up 0.39
bcm), the Iberian Peninsula (up 0.23 bcm),
Germany/Austria (up 0.18 bmc) and France (up 0.15 bcm); |
| --- | --- |
| - | Italy, where volumes grew by
0.22 bcm (2.2%) driven by higher supplies to wholesalers
(up 0.6 bcm) leveraging increasing availability of
production volumes from Eni’s fields in Libya and
higher supplies to the power generation segment (up 0.25
bcm). Sales declined to industrial (down 0.29 bcm) and
residential and commercial users (down 0.26 bcm), the
latter due to mild weather conditions. |

In the first half of 2007, natural gas sales of 48.57 bcm, including own consumption and sales by affiliates and upstream sales in Europe, declined by 3.08 bcm from the first half of 2006, or 6%, due to declining demand in Europe resulting from unusually mild winter weather conditions. Sales in Italy (25.63 bcm) declined by 1.84 bcm, or 6.7%, primarily due to decreased sales to residential (down 0.97 bcm) and industrial users (down 0.76 bcm). Supplies to Italian importers were down by 1.8 bcm. These declines were offset in part by sale growth registered in target markets in the Rest of Europe (up 0.8 bcm), particularly Turkey (up 0.73 bcm), the Iberian Peninsula (up 0.45 bcm), and France (up 0.2 bcm).

Other performance indicators

EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization charges) on an adjusted basis is calculated by adding to adjusted operating profit amortization and depreciation charges on a pro forma basis. This performance indicator, which is not a GAAP measure under either IFRSs or U.S. GAAP, includes Adjusted EBITDA of Eni’s wholly-owned subsidiaries. Eni’s share of adjusted EBITDA of Snam Rete Gas (55%), which is fully-consolidated when preparing consolidated financial statements in accordance with IFRSs. Eni’s share of adjusted EBITDA generated by certain affiliates which are accounted for under the equity method for IFRSs purposes. Management evaluates the performance of Eni’s Gas & Power division also in terms of EBITDA on the basis that the Gas & Power division is comparable to European utilities in the gas and power generation sector. This measure is provided with the intent to assist investors and financial analysts in assessing the Gas & Power divisional performance compared to its European peers, as EBITDA is widely used as the main performance indicator for utilities.

(a) Excludes special items.

The Refining & Marketing division reported an adjusted operating profit of euro 185 million, in line with the second quarter of 2006 (down euro 5 million). This reflected the improved operating performance delivered by the refining business driven by: (i) lower refinery outages for maintenance activity and higher processed volumes and yields; (ii) a favorable trading environment mainly reflecting higher gasoline prices, the effects of which were partially offset by the appreciation of the euro over the dollar.

Marketing activities in Italy reported a lower operating profit mainly due to lower retail margins resulting from rapidly increasing international product prices not fully transferred into retail prices and a decline in wholesale margins for diesel fuels as a result of competitive pressure.

Adjusted net profit for the quarter was euro 137 million, down euro 34 million, or 19.9%, from a year ago.

Adjusted operating profit for the first half of 2007 amounted to euro 305 million, up euro 26 million from the first half of 2006, or 9.3%. This reflected the improved operating performance delivered by the refining business on the back of a favorable trading environment, particularly in the second quarter, and higher volumes processed and higher yields also due to lower maintenance outages. Marketing activities in Italy reported a lower operating profit mainly due to lower retail margins and a decline in wholesale business results due to both lower margins and volumes marketed (down 9.8%), the latter also reflects unusually mild winter weather. The adjusted net profit for the first half of 2007 was euro 250 million, down euro 7 million, or 2.7%.

Special charges excluded from the adjusted operating profit related mainly to environmental provisions and a risk provision relating to an ongoing antitrust proceeding against European authorities (for a total charge of euro 54 million in the second quarter and euro 72 million in the first half).

In the second quarter of 2007 refining throughputs on Eni’s own account (9.32 mmtonnes) were stable as compared to the second quarter of 2006, taking into account expiration of a processing contract at the Priolo refinery owned by third parties occurred at the end of 2006 (down 165 ktonnes in the second quarter, down 660 ktonnes in the first half). Refining throughputs in Italy increased by 2% on a homogeneous basis as a result of better performance at the Sannazzaro refinery due to the circumstance that the catalytic cracking unit was shut down for maintenance in 2006. Outside Italy, own throughput declined by 6.1% due to the standstill of the Schewdt German refinery.

In the first half of 2007 refining throughputs on Eni’s own account (18.32 mmtonnes) increased by 310 ktonnes, or 1.7%. Refining throughputs in Italy increased by 6.8% to 16.1 mmtonnes, on a homogeneous basis, as a result of better performance at the Livorno and Sannazzaro refineries reflecting lower downtime.

In the second quarter of 2007 sales of refined products decreased by 530 ktonnes to 12.02 mmtonnes, down 4.2%, due mainly to lower volumes marketed on wholesale markets in Italy. Eni’s increased marketing initiatives meant that volumes of refined products marketed in the retail market in Italy were stable at 2.19 mmtonnes, despite the decline in domestic consumption. Gasoline sales declined, while diesel fuel sales increased driven by continuing trends in vehicle substitution. Volumes sold to retail markets in the Rest of Europe increased by 40 ktonnes to 0.99 mmtonnes, or 4.2%, mainly in Spain. Sales in the wholesale market in Italy decreased by 240 ktonnes from the second quarter of 2006, to 2.66 mmtonnes, down 8.3%, due to lower demand for heating oil particularly from the power generation sector.

In the first half of 2007, sales of refined products decreased by 510 ktonnes from the first half of 2006, to 24.36 mmtonnes, down 2.1%. This was due to lower volumes sold on wholesale markets in Italy and lower volumes sold to the petrochemical sector reflecting expiration of a processing contract at the Priolo refinery, partly offset by higher volumes sold to oil companies and traders in Italy. Sales of refined products on the retail market in Italy were 4.17 mmtonnes, a 90 ktonnes decline, or 2.1%, due to competitive pressure. Sales in the retail market in the Rest of Europe increased by 70 ktonnes to 1.89 mmtonnes, up 3.8%, mainly in Spain and Germany. Sales in the wholesale market in Italy decreased by 570 ktonnes to 5.27 mmtonnes, down 9.8%, due to lower demand for heating oil from the power generation sector and unusually mild winter weather conditions that impacted sales of heating products (diesel oil and LPG). Sales on the wholesale market in the Rest of Europe increased by 10 ktonnes, to 2.07 mmtonnes, or approximately 1%, primarily in the Czech Republic.

NON-GAAP Measures

Reconciliation of reported operating profit and net profit to results on an adjusted basis

Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Further, finance charges on finance debt, interest income, gains or losses deriving from 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, and exchange rate differences are excluded when determining adjusted net profit of each business segment. The taxation effect of such items excluded from adjusted net profit is determined based on the specific rate of taxes applicable to each item, with the exception for finance charges or income, to which the Italian statutory tax rate of 33% is applied. Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or U.S. GAAP. Management includes them in order to facilitate a comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating return on average capital employed (ROACE) by each business segment.

The following is a description of items which are excluded from the calculation of adjusted results.

Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting.

Special items include certain relevant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items under such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non-recurring material income or charges are to be clearly reported in the management’s discussion and financial tables.

Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition gains or losses on the fair value evaluation of above mentioned derivative financial instruments and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charge pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production division). Finance charges or interest income and related taxation effects excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies.

For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and reported net profit see tables below.

Summarized Group balance sheet (a)

Summarized group balance sheet aggregates the amount of assets and liabilities derived from the statutory balance sheet in accordance with functional criteria which consider the enterprise conventionally divided into the three fundamental areas focusing on resource investments, operations and financing.

Management believes that this summarized group balance sheet is useful information in assisting investors to assess Eni’s capital structure and to 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.

Net borrowings and leverage

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

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

Summarized Group cash flow statement

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

ENI REPORT ON THE SECOND QUARTER OF 2007

BASIS OF PRESENTATION Eni’s accounts at June 30, 2007, unaudited, have been prepared in accordance with the criteria defined by the Commissione Nazionale per le Società e la Borsa (CONSOB) in its regulation for companies listed on the Italian Stock Exchange. Financial information relating to the profit and loss account is presented for the second quarter of 2007 and for the first half of 2006. Financial information relating to balance sheet data is presented at June 30, 2007, March 31, 2007 and December 31, 2006. Tables are comparable with those of 2006 financial statements and the first half report. Eni’s accounts at June 30, 2007 have been prepared in accordance with the evaluation and measurement criteria contained in the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB) and adopted by the European Commission according to the procedure set forth in Article 6 of the European Regulation (CE) No. 1606/2002 of the European Parliament and European Council of July 19, 2002. Non-GAAP financial measures disclosed throughout this report are accompanied by explanatory notes and tables to help investors to gain a full understanding of said measures in line with guidance provided for by recommendation CESR/05-178b. Disclaimer This report contains certain forward-looking statements, in particular in the Outlook section those regarding capital expenditure, dividends, share repurchases, 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. 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.

Second quarter Eni’s net profit for the second quarter of 2007 was euro 2,267 million, down euro 34 million from the second quarter of 2006, or 1.5%, due mainly to a lower operating performance down by euro 729 million, or 14.7%, as a result of a decline in the Exploration & Production and Gas & Power divisions. This reduction in operating profit was offset in part by a euro 558 million decrease in income taxes reflecting lower profit before taxes and an approximately 5 percentage point decline in the Group tax rate (from 53 to 48.1%) as a result of a lower share of profit generated by the Exploration & Production division.

Eni’s adjusted net profit amounted to euro 2,220 million, down 10.6% from the second quarter 2006. Adjusted net profit is arrived at by excluding an inventory holding gain of euro 207 million and special charges of euro 160 million net, resulting in an immaterial adjustment to net profit (down euro 47 million). Special charges for the quarter concerned essentially environmental charges, impairment of mineral assets and employee redundancy incentives, as well as non-recurring charges related to: (i) risk provisions related to ongoing antitrust proceedings against the European antitrust authority; (ii) a gain deriving from the curtailment of the reserve for employee post-retirement benefits relating to Italian companies.

(a) This item concerned mainly intra-group sales of goods, services and capital assets recorded at period end in the equity of the purchasing business segment.

The decline in the Group adjusted net profit was owed to: The reduction of adjusted net profit reported by the Exploration & Production division (down euro 277 million, or 14.4%) due to a weaker operating performance (down euro 739 million, or 17.5%) which was adversely impacted by the appreciation of the euro over the dollar (7.3%), a decline in production sold (down 2.7 mmboe) and higher exploration expenses (down euro 187 million). The reduction of adjusted net profit registered in the Gas & Power division (down euro 220 million, or 34.5%) due to a weaker operating performance (down euro 272 million, or 34.4%) which was adversely impacted by lower natural gas selling margins affected by an unfavorable trading environment and the impact of mild weather on sales volumes, particularly in April. These negative factors were offset in part by positive developments in regulations in Italy due to recently enacted measures by the Italian Authority for Electricity and Gas regarding the indexation of tariffs in the residential segment. Divisional results were also negatively impacted by lower results recorded by equity-accounted entities. These declines in the adjusted net profit were partly offset by a higher adjusted net profit reported in the divisions: Engineering & Construction (up euro 94 million, or 144.6%), reflecting an improved operating performance (up euro 70 million) against the backdrop of favorable demand trends in oilfield services. Petrochemicals (up euro 38 million, or 292.3%), due to an improved operating performance (up euro 62 million) reflecting a recovery in product selling margins and the circumstance that results for the second quarter 2006 were materially affected by an accident occurred at the Priolo refinery resulting in outages at several Eni’s petrochemical plants. The trading environment was affected by slightly lower oil prices with Brent crude prices averaging $68.76 per barrel, down 1.2% compared to the first quarter of 2006, and the appreciation of the euro over the dollar (up 7.3%), as well as lower natural gas selling margins related mainly to the negative trends in energy parameters used in determining purchase and selling prices of natural gas. These negatives were partially offset by an increase in refining margins on the Brent crude marker (up 19.6%). The narrowing of price differentials between light and heavy crude qualities while capping the upside on Eni’s realized refining margins, helped upstream crude realizations which improved somewhat from 2006 as opposed to the trend registered in the Brent crude marker. First half Eni’s net profit for the first half of 2007 was euro 4,855 million, down euro 420 million from the first half of 2006, or 8%, due primarily to a lower operating performance (down euro 1,219 million, or 11.6%) as a result of a decline in the Exploration & Production division, partially offset by a positive performance delivered by Eni's downstream and the Engineering & Construction businesses. This reduction in operating profit was offset in part by lower income taxes (down by euro 874

million) owing to lower profit before taxes and a 2.2 percentage point decline in the Group tax rate (from 49.7 to 47.5%). Eni’s adjusted net profit amounted to euro 4,900 million, down 9.9% from the first half of 2006. Adjusted net profit is arrived at by excluding an inventory holding loss of euro 110 million and special charges of euro 155 million net, resulting in an immaterial adjustment to net profit (up euro 45 million). Return on Average Capital Employed (ROACE) calculated on an adjusted basis for the twelve-month period ending June 30, 2007 was 21.4% (23.5% for the twelve-month period ending June 30, 2006). Assuming Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni as of June 30, 2007, the Group ROACE would stand at 22.1%. The decline in the Group adjusted net profit was owed to: The reduction of adjusted net profit recorded in the Exploration & Production division (down euro 963 million, or 24%), due to a weaker operating performance (down euro 1,858 million, or 21.9%) which was adversely impacted by the appreciation of the euro over the dollar (8.1%), a decline in production sold (down 12.2 mmboe), higher exploration expenses, and lower realizations in dollars (down 2.1%). Performance in this segment was negatively affected also by the two percentage point increase in the adjusted tax rate (from 52.8% to 54.5%) due to changes in the fiscal regime of the United Kingdom and Algeria enacted in the second half of 2006 and Algeria enacted in the second half of 2006. These declines in the adjusted net profit were partly offset by a higher adjusted net profit reported in the divisions: Engineering & Construction (up euro 152 million, or 100%), reflecting an improved operating performance (up euro 168 million) against the backdrop of favorable demand trends in oilfield services. Petrochemicals (up euro 101 million, or 348.3%), due to an improved operating performance (up euro 161 million), reflecting a recovery in product selling margins and the impact of the accident occurred at the Priolo refinery on the results for the first half of 2006 . Gas & Power (up euro 60 million, or 4%), due to a better operating performance (up euro 208 million, or 10.4%) reflecting essentially positive developments in the regulatory framework in Italy and the circumstance that certain purchase charges were incurred in the first quarter of 2006 owing a climatic emergency for the 2005 - 2006 winter. These positive factors were offset in part by the impact of unusually mild weather conditions affecting natural gas sales by consolidated subsidiaries (down 2.8 bcm, or 6.2%), offset in part by volume increases in target markets in Europe. Divisional results were also negatively impacted by lower results recorded by equity-accounted entities. The trading environment was affected by lower oil prices with Brent crude prices averaging $63.26 per barrel, down 3.7% compared to the first half of 2006, and the appreciation of the euro over the dollar (up 8.1%). These negatives were partially offset by increased refining margins on the Brent crude marker (up 14.2%) and higher selling margins on petrochemical products. Overall, the first half trading environment had no material impact on natural gas selling margins.

ENI REPORT ON THE SECOND QUARTER OF 2007

Second quarter Eni’s net sales from operations (revenues) for the second quarter of 2007 (euro 19,754 million) were down euro 985 million, a 4.7% decline from the second quarter of 2006, primarily reflecting the impact of the appreciation of the euro versus the dollar (up 7.3%) and the decline in natural gas prices, and in sold production of hydrocarbons (down 2.7 mmboe). These negative factors were offset in part by higher activity levels in the Engineering & Construction and Petrochemical segments and higher refined products dollar prices. First half Eni’s net sales from operations (revenues) for the first half of 2007 (euro 41,667 million) were down euro 2,656 million, a 6% decline from the first half of 2006, primarily reflecting the impact of the appreciation of the euro versus the dollar (up 8.1%) and the decline in hydrocarbon prices, as well as lower sold production of hydrocarbons (down 12.2 mmboe) and lower sales of natural gas (down 2.8 bcm). These negative factors were offset in part by higher activity levels in the Engineering & Construction and Petrochemical segments. Revenues generated by the Exploration & Production segment (euro 12,829 million) declined by euro 1,630 million, down 11.3%, essentially due to the impact of the appreciation of the euro versus the dollar, lower hydrocarbon production sold (down 12.2 mmboe, or 3.9%) and the decline in realizations in dollars (down 2.1%). Revenues generated by the Gas & Power segment (euro 13,722 million) declined by euro 1,211 million, down 8.1%, mainly due to lower natural gas volumes sold by consolidated subsidiaries (down 2.8 bcm or 6.2%) and lower volumes transported and distributed as a consequence of an unusually mild winter weather, as well as the negative trends of energy parameters to which gas prices are contractually indexed. Revenues generated by the Refining & Marketing segment (euro 16,880 million) declined by euro 2,566 million, down 13.2%, mainly due to lower international prices for oil and the effect of the appreciation of the euro over the dollar. Revenues generated by the Petrochemical segment (euro 3,476 million) increased by euro 136 million from the first half of 2006, up 4.1%, reflecting mainly the fact that performance in the first half of 2006 had been impacted by an accident occurred at the Priolo refinery resulting in a nearly total standstill of a number of Eni’s petrochemicals plants. Net sales from operations generated by the Engineering & Construction segment (euro 4,269 million) increased by euro 1,189 million, up 38.6%, due to increased activity levels in the Offshore and Onshore construction businesses.

Operating expenses for the first half of 2007 (euro 29,494 million) declined by euro 1,625 million from the first half of 2006, down 5.2%, essentially due to the appreciation of the euro versus the dollar. Other factors behind this reduction were: (i) lower purchase prices for natural gas and light oil-based refinery feedstocks; (ii) lower supplies of natural gas in line with lower sales and the fact that in the first quarter of 2006 certain gas supplies charges were recorded due to a climatic emergency for the 2005-2006 winter; (iii) lower costs for refinery maintenance activity. Labor costs (euro 1,777 million) increased by euro 41 million, up 2.4%, due mainly to an increase in unit labor costs in Italy and outside Italy and an increase in the average number of employees outside Italy in the Engineering & Construction segment related to higher activity levels. These increases were offset in part by exchange rate differences and a euro 74 million non-recurring gain deriving from the curtailment of the reserve for post-retirement benefits existing at 2006 year-end related to obligations towards Italian employees. In fact, the Italian budget law for 2007 modified Italian regulation for post-retirement benefits resulting in a change from a defined benefit plan to a defined contribution one. Following this, the reserve was reassessed to take account of the exclusion of future salaries and relevant increases from actuarial calculations.

The 284 employee increase was related mainly to the positive balance of hiring and dismissals (257 employees) related to changes in consolidation. In the first half of 2007 a total of 1,121 employees were hired, of these 799 on open-end contracts and 864 employees were dismissed (of these 503 employees on open-end contracts). Outside Italy employees were 35,792, with a 1,985 employee increase mainly concerning fixed-term workers in the Engineering & Construction segment.

Adjusted operating profit is arrived at by excluding an inventory holding gain of euro 262 million and special charges of euro 240 million net. The Group operating profit was dragged down by a weaker operating performance recorded in the Exploration & Production division, due primarily to the euro’s appreciation against the dollar (7.3%), lower sold production volumes and higher exploratory expenses, and the Gas & Power division affected by declining selling margins and the impact of mild weather on sales volumes, particularly in April. First half Adjusted operating profit for the first half was euro 9,449 million, down 10.7% from a year ago. Adjusted operating

profit is arrived at by excluding an inventory holding gain of euro 107 million and special charges of euro 233 million net. The main factor affecting this decline was a weaker operating performance reported by the Exploration & Production division (down euro 1,858 million from the first half 2006, or 21.9%), due primarily to a 8.1% appreciation of the euro versus the dollar, lower production sold (down 12.2 mmboe), higher expenses incurred in connection with exploratory activity and lower realizations in dollars (down 2.1%). This decline was partly offset by an increase in adjusted operating profit reported by the following segments: Gas & Power (up euro 208 million or 10.4%), mainly owing to a favorable evolution of the regulatory framework in Italy and the fact that in the first quarter of 2006 certain supply charges were recorded due to a climatic emergency related to the winter time 2005-2006. These positives were partly offset by a decline in marketed volumes of natural gas (down 2.80 bcm, or 6.2%) due to lower European gas demand affected by unusually mild winter weather conditions, partly offset by a sale growth in target markets in the Rest of Europe; Engineering & Construction (up euro 168 million or 79.6%) due to a positive trend in the market for oilfield services; Petrochemicals (up euro 161 million or 575%) reflecting a recovery in product selling margins and the circumstance that results for the second quarter 2006 were materially affected by an accident occurred at the Priolo refinery resulting in outages at several Eni’s petrochemical plants. Net financial income In the first half of 2007 net financial income (euro 25 million) decreased by euro 126 million from the first half of 2006. This decrease was due mainly to the circumstance that fair value gains were recognized on certain financial derivatives instruments in the first half of 2006 as compared to a fair value loss recorded for these instruments in the first half of 2007. Fair value changes on these financial instruments are recorded in the profit and loss account instead of being recognized in connection with related assets, liabilities and commitments because these instruments do not meet the formal criteria to be assessed as hedges under IFRS, including the time value component (for a loss of euro 47 million) of certain cash flow hedges Eni entered into to hedge commodity risk in connection with the acquisitions of proved and unproved upstream properties executed in the first half of 2007 (for more details on this issues see the Balance sheet discussion – under the paragraph net working capital). This negative was partly offset by: (i) a euro 62 million net gain upon fair value valuation through profit and loss account of both the 20% interest in OAO Gazprom Neft and the related call option guaranteed by Eni to Gazprom related to this interest. This net gain is equal to the remuneration of the capital employed according to the contractual arrangements between the two partners (for more details on this issues see the Balance sheet discussion – under the paragraph net working capital); (ii) a reduction in net finance expenses as a result of a reduction in average net borrowings, the impact of which was partly offset by higher interest rates on euro (Euribor up 1.1 percentage points) and dollar loans (Libor up 0.6 percentage points) .

Income taxes were euro 4,673 million, down euro 874 million, or 15.8%, due primarily to lower income before taxes (down euro 1,321 million). The 47.5% Group tax rate declined by 2.2 percentage points from the first half of 2006 reflecting: (i) a lower share of profit before taxes generated by the Exploration & Production division; (ii) the recognition of deferred tax assets related to an increase in assets and liabilities carrying amounts for tax purposes on part of certain Italian subsidiaries upon renewal of the Group option for the Italian consolidated statement for tax purposes. Adjusted tax rate was down one percentage point to 47.4% (48.4% in the first half 2006),which is calculated as ratio of net profit before taxes to income taxes on an adjusted basis. Minority interest Minority interest ’s share of profit was euro 311 million and was related to Snam Rete Gas (euro 139 million) and Saipem (euro 164 million).

SUMMARIZED GROUP BALANCE SHEET

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

At June 30, 2007, net capital employed totaled euro 51,418 million, representing an increase of euro 3,452 million from December 31, 2006.

ENI REPORT ON THE SECOND QUARTER OF 2007

Fixed assets Fixed assets totaled euro 56,947 million, representing an increase of euro 2,713 million from December 31, 2006 (euro 54,234 million) due to capital expenditures (euro 4,257 million) and acquisition of assets and investments (euro 2 billion, of which euro 958 million related to gas assets ex-Yukos and approximately euro 1 billion for the purchase of Maurel & Prom assets onshore Congo; the 20% interest in OAO Gazprom Neft was accounted in the net working capital - see below), partly offset by provisions for depreciation, amortization and impairments (euro 3,306 million) and the effect of the appreciation of the euro over the dollar in the translation of financial statements of subsidiaries operating with currencies other than the euro. Other assets include, for a book value of $829 million (corresponding to euro 614 million at the June 30, 2007 EUR/USD exchange rate), the assets related to the service contract for oil activities in the Dación area of the Venezuelan branch of Eni’s subsidiary Eni Dación BV. With effective date April 1, 2006, the Venezuelan State oil company Petróleos de Venezuela SA (PDVSA) unilaterally terminated the Operating Service Agreement (OSA) governing activities at the Dación oil field where Eni acted as a contractor, holding a 100% working interest. As a consequence, starting at the same date, operations at the Dación oil field are conducted by PDVSA. Eni proposed to PDVSA to agree in terms in order to recover the fair value of its Dación assets. On November 2006, based on the bilateral investments treaty in place between the Netherlands and Venezuela (the "Treaty " ), Eni commenced a proceeding before the International Centre for Settlement of Investment Disputes (ICSID) Tribunal (i.e., a tribunal acting under the auspices of the ICSID Convention and being competent pursuant to the Treaty) to claim its rights. Despite this action, Eni is still ready to negotiate a solution with PDVSA to obtain a fair compensation for its assets. Based on the opinion of its legal consultants, Eni believes to be entitled to a compensation for such expropriation in an amount equal to the market value of the OSA before the expropriation took place. The market value of the OSA depends upon its expected profits. In accordance with established international practice, Eni has calculated the OSA’s market value using the discounted cash flow method, based on Eni’s interest in the expected future hydrocarbon production and associated capital expenditures and operating costs, and applying to the projected cash flow a discount rate reflecting Eni’s cost of capital as well as the specific risk of concerned activities. Independent evaluations carried out by a primary petroleum consulting firm fully support Eni’s internal evaluation. The estimated net present value of Eni’s interest in the Dación field, as calculated by Eni, is higher than the net book value of the Dación assets which consequently have not been impaired. In accordance with the ICSID Convention, a judgement by the ICSID Tribunal awarding compensation to Eni would be binding upon the parties and immediately enforceable as if it were a final judgement of a court of each of the States that have ratified the ICSID Convention. The ICSID Convention was ratified in 143 States. Accordingly, if Venezuela fails to comply with the award and to pay the compensation, Eni could take steps to enforce the award against commercial assets of the Venezuelan Government almost anywhere those may be located (subject to national law provisions on sovereign immunity). In the item Investments is included a 60% interest in Eni Russia BV which owns 100% interest in three Russian companies acquired on April 4, 2007 in partnership with Enel, following award of a bid for Lot 2 in the Yukos liquidation procedure. These three companies – OAO Artic Gas, OAO Urengoil and OAO Neftegaztechnologia – are engaged in exploration and development of gas reserves. Eni and Enel granted to Gazprom a call option to acquire a 51% interest in these acquired companies to be exercisable by Gazprom within 24 months starting from the acquisition date. Eni evaluates his investment in Eni Russia BV under the equity method accounting as it jointly controls the three entities based on ongoing contractual arrangements, therefore exercising significant influence in the financial and operating policy decisions of the investees. This proportion allocated of 60% is the present ownership interest of Eni in the acquired companies determined by not taking into account the eventual exercise of the call option by Gazprom. Net working capital At June 30, 2007, net working capital totaled (euro 4,645 million), representing an increase of euro 552 million from December 31, 2006 mainly due to: (i) the acquisition of a 20% interest in the Russian company OAO Gazprom Neft (see below); (ii) a receivable upon a dividend approved by OAO Gazprom Neft on June 22, 2007; this dividend has not yet been distributed. These factors were partly offset by decreases in connection with the following items: (i) higher taxes payable and an increase in the net reserve for deferred taxation related to taxes due for the period and the fact that excise taxes on oil products marketed in Italy in the first 15 days of December are settled within the

end of this month, instead of being paid in the following month as in the rest of the year. These factors were partly offset by the payment of the balance of income taxes by Italian companies for 2006; (ii) a euro 892 million loss recognized on the fair value evaluation of certain cash flow hedges, which the Group entered into in order to hedge cash flows expected in the 2008-2011 period from the sale of approximately 2% of Eni’s proved hydrocarbon reserves as of 2006 year-end in connection with its purchase of certain oil producing assets and proved and unproved property onshore in Congo (from the French company Maurel & Prom) and in the Gulf of Mexico (from the US company Dominion) finalized in May and early in July 2007, respectively. In light of this, Eni put in place certain forward sale contracts at a fixed price and call and put options with the same date of exercise. These options can be exercised in presence of crude oil market prices higher or lower compared with contractual prices. This treatment does not apply to the time value component (a euro 47 million loss) arising from market price fluctuations within the range provided by these call and put options which is recognized in the profit and loss account under the item net financial expenses because the hedging relationship is ineffective. This loss was partly offset by gains recorded on the fair value evaluation of certain derivative financial instruments, which do not meet the formal criteria to be recognized as hedges under IFRS, reflecting the depreciation of the US dollar. In the item Equity instruments is included the carrying amount of a 20% interest in OAO Gazprom Neft acquired on April 4, 2007 following finalization of a bid within the Yukos liquidation procedure. This entity is currently listed at the London Stock Exchange. This accounting classification reflects the circumstance that Eni granted to Gazprom a call option on the entire 20% interest to be exercisable by Gazprom within 24 months starting from the acquisition date, at a price of $3.7 billion equaling the bid price, as modified by subtracting dividends received and adding possible share capital increases, a contractual remuneration on the capital employed and financing collateral expenses. In accordance with the fair value option provided for by IAS 39, Eni evaluated its 20% interest in OAO Gazprom Neft at fair value with changes in fair value recognized through the profit or loss account instead of net equity. Eni elected this way in order to eliminate a recognition inconsistency that would otherwise arise from measuring both the equity instrument and the related call option on different bases. In fact, the call option granted to Gazprom is measured at fair value through profit or loss being a derivative instrument. Consequently, the carrying amount of this equity instrument is determined based on its fair value as expressed by current quoted market prices, as reduced by the fair value amount of the relevant call option, thus equaling the option strike price as of June 30, 2007. The share of the Exploration & Production, Gas & Power and Refining & Marketing divisions on net capital employed was 89% (90% at December 31, 2006).

Return On Average Capital Employed (ROACE)

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

Net borrowings and leverage

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

Net borrowings at June 30, 2007 were euro 9,122 million, representing an increase of euro 2,355 million from December 31, 2006. The high level of cash inflow generated by operating activities (euro 9,703 million) affected by seasonality in demand for natural gas and certain refined products, cash from divestments and currency translation effects, were offset by the cash outflows related to: (i) the acquisition of investments and assets (euro 4.8 billion) mainly relating to the 20% interest in OAO Gazprom Neft and an interest in three Russian companies engaged in developing natural gas following finalization of a bid procedure for ex-Yukos assets (euro 3,729 million) and the purchase of oil producing assets onshore Congo (approximately euro 1 billion); (ii) capital expenditures totaling euro 4,257 million; (iii) dividend payments (euro 2,611 million, of which euro 2,384 million concerning the balance of the 2006 dividend by the parent company Eni SpA and euro 149 and euro 71 million were paid by Snam Rete Gas SpA and Saipem SpA, respectively); (iv) the repurchase of own shares by Eni SpA for euro 339 million, and by Snam Rete Gas SpA for euro 336 million. From January 1 to June 30, 2007, a total of 13.83 million own shares were purchased by the company for a total amount of euro 339 million (representing an average cost of euro 24.504 per share). Since the inception of the share buy-back programme (September 1, 2000), Eni has repurchased 349 million shares, equal to 8.71% of outstanding capital stock, at a total cost of euro 5,851 million (representing an average cost of euro 16.774 per share). Total debt amounted to euro 16,141 million, of which 9,061 million were short-term (including the portion of long-term debt due within 12 months for euro 930 million) and euro 7,080 million were long-term. At June 30, 2007, leverage – ratio between net borrowings and shareholders’ equity – was 0.22 compared with 0.16 at December 31, 2006. Assuming Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni as of June 30, 2007, leverage would stand at 0.14. Net borrowings increased of euro 5,270 million from March 31, 2007, due to: (i) the acquisition of a 20% interest in OAO Gazprom Neft and an interest in the three Russian companies engaged in developing natural gas following finalization of a bid procedure for ex-Yukos assets (euro 3,729 million); (ii) the purchase of oil producing assets onshore Congo (approximately euro 1 billion); (iii) capital expenditures totaling euro 2.244 million; (iv) dividend payments (euro 2,611 million) and the repurchase of own shares by Eni SpA for euro 138 million, and by Snam Rete Gas SpA for euro 242 million. These outflows were partially offset by cash inflow generated by operating activities in the quarter (euro 4,140 million).

SUMMARIZED CASH FLOW STATEMENT AND CHANGE IN NET BORROWINGS

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

ENI REPORT ON THE SECOND QUARTER OF 2007

Capital expenditures of the Exploration & Production segment (euro 2,837 million) concerned essentially development of oil and gas reserves directed mainly outside Italy, in particular Kazakhstan, Egypt, Angola and Congo. Development expenditures in Italy concerned in particular the well drilling programme and other activities in Val d’Agri and sidetrack and infilling work in mature areas. About 92% of exploration expenditures were directed outside Italy in particular Egypt, the Gulf of Mexico, Norway, Nigeria and Indonesia. In Italy, exploration activities were directed mainly to the offshore of Sicily. Acquisition of proved and unproved property concerned mainly a 70% interest in the Nikaitchuq oilfield in Alaska, in which Eni reached a 100% ownership. As compared to the first half of 2006, capital expenditures increased by euro 723 million, up 34.2%, due in particular to the increase in exploration expenditures in the Gulf of Mexico, Norway, Indonesia, and Egypt and higher development expenditures in Congo, Egypt and Angola. In the second quarter of 2007 the Exploration & Production segment acquired assets (for approximately euro 4.8 billion) concerning mainly the 20% stake in OAO Gazprom Neft and a stake in three Russian companies in the upstream gas sector following the bid for the purchase of ex-Yukos assets (euro 3.7 billion) and the acquisition of oil assets onshore Congo (approximately euro 1 billion).

Capital expenditures in the Refining & Marketing segment amounted to euro 319 million and concerned: (i) refining, supply and logistics in Italy (euro 214 million), in particular actions for improving flexibility and yields of refineries, among which the construction of a new hydrocracking unit at the Sannazzaro refinery; (ii) the upgrading of the retail network in Italy (euro 49 million); and (iii) the upgrading of the retail network and the purchase of service stations in the Rest of Europe (euro 36 million). The 37.5% increase from the first half of 2006 was due mainly to the start-up of the refinery upgrade programme.

Engineering & Construction Capital expenditure in the Engineering & Construction segment amounted to euro 510 million and concerned: (i) the construction start-up of the new semisubmersible platform Scarabeo 8 and a new pipelayer and a new deepwater drilling ship Saipem 12000; and (ii) conversion of two tanker ships into FPSO vessels that will operate in Brazil on the Golfinho 2 field and in Angola.

ENI REPORT ON THE SECOND QUARTER OF 2007

OUTLOOK FOR 2007

The outlook for Eni in 2007 remains positive, with key business trends for the year as follows: Production of liquids and natural gas is forecast to remain at the same level as 2006 (actual oil and gas production averaged 1.77 mmboe/d in 2006) under the assumption of full-year Brent crude oil prices at $55 per barrel. Production decreases due to escalating social unrest in Nigeria and the loss of the Dación oilfield in Venezuela and mature field production declines are expected to be offset by the contribution from acquired properties in the Gulf of Mexico and Congo and ongoing build-up in gas production in Libya. Sales volumes of natural gas worldwide are expected to increase by a small amount from the previous year (actual sales volumes in 2006 were 97.48 bcm). Growth is expected to be achieved in European target markets in terms of both market share and volumes gains, mainly in Spain, France and Germany/Austria markets. Sales volumes in Italy are expected flat as a result of a planned recovery in the second half of 2007, with the main increases expected in the residential segment in connection with ongoing marketing actions. Sales volumes of electricity are expected to increase approximately 4% from 2006 (actual volumes in 2006 were 31.03 TWh), due to an expected increase in traded volumes. Refining throughputs on Eni’s account are forecast to remain practically unchanged from 2006 (actual throughputs in 2006 were 38.04 mmtonnes), reflecting higher volume performance expected at the Livorno, Gela and Sannazzaro refineries; on the negative side, a processing contract expired late in 2006 at the Priolo refinery owned by a third party affecting throughputs for the full 2007. Retail sales of refined products are expected to slightly increase from 2006 (actual volumes sold in 2006 were 12.48 mmtonnes), driven by sale expansion in Europe as a result of a greater number of service stations, also following acquisitions in target markets. Sales on the Italian market are expected to remain unchanged despite a decline in domestic consumption boasted by undertaken marketing initiatives. In 2007 management expects Eni’s capital expenditures on exploration and capital projects to amount to approximately euro 10.6 billion, including expenditures for developing acquired upstream assets, representing a 35% increase over 2006. Approximately 86% of this capital expenditure programme is expected to be deployed in the Exploration & Production, Gas & Power and Refining & Marketing divisions. Furthermore, acquisitions of assets and interests amounting to euro 9.4 billion are forecast for 2007, of which euro 4.8 billion related to deals finalized in the first half of the year (namely the acquisition of ex-Yukos assets and proved and unproved oil properties onshore Congo), with the residual euro 4.6 billion amount related to transactions which will be accounted in investing cash flows for the second half of the year (namely the purchase of upstream assets in the Gulf of Mexico, and refining and marketing assets in the Central-Eastern Europe). Assuming Gazprom exercises its call options to purchase a 20% interest in OAO Gazprom Neft and a 51% interest in ex-Yukos gas assets from Eni, net cash outflows used in investing activities will decrease to euro 16.5 billion. On the basis of the expected cash outflows for planned capital expenditures and acquisitions, and shareholders remuneration, also assuming a $55/barrel scenario for the Brent crude oil, Eni foresees its leverage to settle in the low or high end of a 0.3/0.4 range by the end of the year, depending on the exercise of the above mentioned call options by Gazprom.

Results

Second quarter Adjusted operating profit for the second quarter 2007 was euro 3,483 million, a decrease of euro 739 million from the second quarter 2006, or 17.5%, due primarily to: (i) an adverse impact of the appreciation of the euro versus the dollar; (ii) lower production sold, which was down 2.7 mmboe; (iii) higher expenses incurred in connection with exploration activity (euro 187 million; euro 213 million on a constant exchange rate basis); (iv) higher production costs and amortization/depreciation charges also reflecting the impact of sector specific inflation.

ENI REPORT ON THE SECOND QUARTER OF 2007

Oil and gas realizations in dollars were substantially stable due to higher liquid realizations which benefited from narrowing differentials between heavy and light crude recorded in the quarter, partly offset by lower gas realizations. The adjusted net profit was euro 1,647 million, down euro 277 million, down 14.4% from the second quarter of 2006, due essentially to a weaker operating performance. Special charges excluded by the adjusted operating profit of euro 65 million concerned mainly impairment of assets. First half Adjusted operating profit recorded for the first half of 2007 amounted to euro 6,615 million, down euro 1,858 million or 21.9% from the first half of 2006, due mainly to: (i) the adverse impact of the appreciation of the euro over the dollar (approximately euro 580 million); (ii) a decline in production sold (down 12.2 mmboe); (iii) higher exploration expenses (euro 376 million, euro 426 million at constant exchange rates); (iv) lower product realizations in dollars (down 2.1%); and (v) higher production costs and amortization charges. Adjusted net profit of euro 3,056 million declined by euro 963 million, down 24% from the first half of 2006 due to a weaker operating performance and a two percentage point increase in the adjusted tax rate (from 52.8% to 54.5%) due to changes in the fiscal regime of the United Kingdom and Algeria enacted in the second half of 2006. Special charges excluded by the adjusted operating profit of euro 65 million concerned mainly impairment of assets.

ENI REPORT ON THE SECOND QUARTER OF 2007

Second quarter Oil and natural gas production in the second quarter of 2007 averaged 1,736 kboe/d, a decrease of 12 kboe/d compared to the same period last year (down 0.7%). This reduction was due primarily to the negative impact of disruptions resulting from continuing social unrest in Nigeria. Factoring in this effect, oil and natural gas production level was in line with the first quarter 2006. Production increases were achieved mainly in Libya, Kazakhstan and the Gulf of Mexico, in addition to the effect of recently acquired oil assets in Congo, which offset mature field declines in Italy and the United Kingdom and the effect of facilities shutdowns in Norway. Production achieved outside Italy amounted to 88% of total production (86% in the second quarter of 2006). Daily production of oil and condensates (1,026 kbbl) decreased by 30 kbbl, or 2.8% from the second quarter 2006. Production decreases were reported mainly in: (i) Nigeria due to the above mentioned causes; (ii) the United Kingdom due to mature field decline in the Liverpool Bay area and at the McCulloch field (Eni’s interest 40%); (iii) facility outages at the Ekofisk field (Eni’s interest 12.39%) in Norway. Main increases were registered in: (i) Kazakhstan due to a better facility performance and also to the fact that maintenance activities were performed in 2006 at the Karachaganak field (co-operated by Eni with a 32.5% interest); (ii) the United States due to the resumption of full activity at plants damaged by hurricanes in the second half of 2005; and (iii) Libya due to the build-up of the Bahr Essalam field (Eni’s interest 50%). Daily production of natural gas for the second quarter (4.082 mmcf/d) increased by 108 mmcf, or 2.7% mainly as a result of the build-up of the Western Libyan Gas Project in Libya, a better performance of Norway’s Aasgard (Eni’s interest 14.81%) and Kristin (Eni’s interest 8.25%) fields. Gas production in Italy decreased due to mature field declines. First half Oil and natural gas production for the first half of 2007 averaged 1,735 kboe/d, a decrease of 52 kboe/d compared to the same period last year (down 2.9%). In addition to Nigerian events, production performance for the period was impacted by the loss of production at the Venezuelan Dación oilfield (down 31 kbbl/d) as a consequence of the unilateral cancellation of the service agreement for the field exploitation by the Venezuelan State Oil Co PDVSA effective April 1, 2006. When factoring in these two events, production was barely flat from the first half of 2006. Production increases were achieved mainly in Libya, Kazakhstan and the Gulf of Mexico offsetting mature field declines in Italy and the United Kingdom and facility shutdowns in Norway. Oil and natural gas production share outside Italy was 87% (86% in the first half of 2006). Daily production of oil and condensates (1,028 kbbl) decreased by 71 kbbl, or 6.5% from the first half 2006. Production decreases were reported mainly in Venezuela, Nigeria and the North Sea due to the above mentioned causes. Main increases were registered in: (i) Kazakhstan due to better performance of the Karachaganak field and also to the fact that maintenance activities were performed in 2006; (ii) the United States due to the resumption of full activity at plants damaged by hurricanes in the second half of 2005. Daily production of natural gas for the first half of 2006 (4.063 mmcf/d) increased by 113 mmcf, or 2.7% mainly in Libya as a result of the build-up of the Bahr Essalam field, in Norway due to increased production of the Aasgard and Kristin fields and Nigeria, due to increased supplies to the Bonny LNG plant. Gas production in Italy decreased due to mature field declines.

Results Second quarter Adjusted operating profit for the second quarter of 2007 was euro 519 million, representing a decline of euro 272 million, or 34.4%. This was due mainly to a decline in gas selling margins due to an unfavorable trading environment and the impact of mild weather on gas sales, particularly in April. This negative factor was partly offset by the positive impact of a favorable evolution of the regulatory framework in Italy. This reflected enactment of Resolution No. 79/2007 by the Authority for Electricity and Gas implementing a more favorable indexation mechanism of the raw material cost component in supplies to residential and commercial users as compared to

the one in force in the first half of 2006 as established by Resolution No. 248/2004. Adjusted net profit of the second quarter of 2007 decreased by euro 220 million to euro 418 million, down 34.5%, due to lower adjusted operating profit and a lower performance recorded by certain affiliates accounted for under the equity method of accounting. First half Adjusted operating profit for the first half of 2007 increased by euro 208 million to euro 2,202 million, up 10.4%, notwithstanding the occurrence of unusually mild winter weather conditions resulting in lower volumes sold of natural gas by consolidated subsidiaries (down 2.8 bcm, or 6.2%). Despite this negative, divisional results were driven by: (i) the impact of a favorable evolution of the regulatory framework in Italy. This reflected enactment of Resolution No. 79/2007 by the Authority for Electricity and Gas as discussed above; (ii) supply charges incurred in the same period last year caused by a climatic emergency for the winter time 2005-2006. The favorable trends recorded in the first quarter reversed in the second quarter relating to trading environment determining gas selling margins, resulting in an immaterial impact for the first half. Adjusted net profit for the first half 2007 was euro 1,577 million, representing an increase of euro 60 million over the first half of 2006, up 4%. This reflected higher adjusted operating profit, offset in part by a lower performance recorded by certain affiliates accounted for under the equity method of accounting.

EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization charges) on an adjusted basis is calculated by adding to adjusted operating profit amortization and depreciation charges on a pro forma basis. This performance indicator, which is not a GAAP measure under either IFRSs or U.S. GAAP, includes: Adjusted EBITDA of Eni’s wholly-owned subsidiaries; Eni’s share of adjusted EBITDA of Snam Rete Gas (55%), which is fully consolidated when preparing consolidated financial statements in accordance with IFRSs; Eni’s share of adjusted EBITDA generated by certain affiliates which are accounted for under the equity-method for IFRSs purposes. Management evaluates performance in Eni’s Gas & Power division also on the basis of this measure taking account of the evidence that this division is comparable to European utilities in the gas and power generation sector. This measure is provided with the intent 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.

Second quarter In the second quarter of 2007, natural gas sales of 20.43 bcm, including own consumption and sales by affiliates and upstream sales in Europe were marginally lower compared with the same period a year ago due to the impact of mild weather, particularly in April. The main decrease was recorded in supplies to Italian importers (down 1.18 bcm) due to lower take-or-pay contract off-takes reflecting outages at certain power generation plants. Also volumes produced in the North Sea declined by 0.21 bcm. In an increasingly competitive market, sales in the Italian market were 10.21 bcm with an increase of 0.22 bcm, or 2.2%. This increase reflects higher sales to: (i) wholesalers (up 0.6 bcm), reflecting increasing availability of production volumes from Eni’s fields in Libya, and (ii) to power generation (up 0.25 bcm). These positives were offset in part by lower sales to industrial users (down 0.29 bcm) and to residential clients (down 0.26 bcm). Sales under the gas release 2 program (0.46 bcm) declined by 0.08 bcm. Own consumption 3 (1.48 bcm) declined by 0.13 bcm, or 8.1%, due to lower supplies to EniPower. Gas sales in target markets of the Rest of Europe were 4.93 bcm with an increase of 1.08 bcm, or 28.1%, due to growth registered in: (i) Turkey (up 0.39 bcm); (ii) the Iberian Peninsula (up 0.23 bcm); (iii) Germany/Austria (up 0.18 bmc); (iv) France (up 0.15 bcm). In particular, natural gas sales of Eni’s affiliates in the Rest of Europe (net to Eni and net of Eni’s supplies) amounted to 1.33 bcm, a 0.05 bcm decline related in particular to: (i) GVS (Eni’s interest 50%) with 0.46 bcm; (ii) Unión Fenosa Gas (Eni’s interest 50%) with 0.28 bcm. Sales outside Europe (0.68 bcm) increased by 0.2 bcm from the second quarter of 2006 or 41.7% due to higher supplies to the Argentinean market and international sales of Unión Fenosa Gas (Eni’s interest 50%) up 0.3 bcm. Eni transported 18.38 bcm of natural gas in Italy, a decrease of 3.25 bcm from the second quarter of 2006, down 15%, due to a decline in domestic demand. Volumes transported on behalf of third parties declined by 0.5 bcm, those transported on behalf of Eni declined by 2.75 bcm. Sales of electricity (8.86 TWh) increased by 1.2 TWh, up 15.7%.

ENI REPORT ON THE SECOND QUARTER OF 2007

First half In the first half of 2007, natural gas sales of 48.57 bcm, including own consumption and sales by affiliates and upstream sales in Europe, declined by 3.08 bcm from the first half of 2006, or 6%, due to declining demand in Europe resulting from unusually mild winter weather conditions. In an increasingly competitive market, sales in the Italian market were 25.63 bcm with a decline of 1.84 bcm, or 6.7%, due in particular to lower sales to residential and commercial users (down 0.97 bcm), to industrial users (down 0.76 bcm) and to power generation (down 0.09 bcm), offset in part by higher sales to wholesalers (up 0.16 bcm). Sales under the gas release program (0.95 bcm) declined by 0.18 bcm. Own consumption (2.87 bcm) declined by 0.21 bcm, or 6.8%, due to lower supplies to EniPower. Sales to importers into Italy declined by 1.8 bcm due to lower offtakes related to weather conditions and standstills of power plants. Gas sales in target markets of the Rest of Europe were 11.48 bcm with an increase of 0.8 bcm, or 7.5%, due to growth registered in: (i) Turkey (up 0.73 bcm); (ii) the Iberian Peninsula (up 0.45 bcm); (iii) France (up 0.2 bcm). In particular, natural gas sales of Eni’s affiliates in the Rest of Europe (net to Eni and net of Eni’s supplies) amounted to 3.43 bcm, a 0.28 bcm decline related in particular to: (i) GVS (Eni’s interest 50%) with 1.39 bcm; (ii) Unión Fenosa Gas (Eni’s interest 50%) with 0.85 bcm. Sales outside Europe (0.94 bcm) increased by 0.23 bcm and concerned in particular Unión Fenosa Gas (Eni’s interest 50%) up 0.43 bcm.

Results Second quarter The Refining & Marketing division reported an adjusted operating profit of euro 185 million, substantially in line with the second quarter of 2006 (down euro 5 million). This reflected a better operating performance delivered by the refining business driven by: (i) lower refinery outages for maintenance activity; (ii) a favorable trading environment (the margin on Brent was up $1.13 bbl, or 19.6%) mainly reflecting higher gasoline prices, whose effects were offset in part by the appreciation of the euro over the dollar. Marketing activities in Italy reported a lower operating profit due mainly to lower retail margins resulting from rapidly increasing international product prices not fully transferred onto to retail prices and a decline in wholesale margins for diesel fuels owing to intense competitive pressure. Adjusted net profit for the quarter was euro 137 million, down euro 34 million, or 19.9%, from a year ago. Special charges excluded from the adjusted operating profit concerned mainly environmental provisions and a risk provision related to an ongoing antitrust proceeding against European authorities (for a total charge of euro 54 million). First half Adjusted operating profit for the first half of 2007 amounted to euro 305 million, up euro 26 million from the first half of 2006, or 9.3%. This reflected a better operating performance delivered by the refining business on the back of a favorable trading environment, particularly in the second quarter, and higher volumes processed and higher yields also due to lower maintenance outages. Marketing activities in Italy reported a lower operating profit due mainly to lower retail margins and a decline in

wholesale business results due to both lower margins and volumes marketed (down 9.8%), the latter also reflecting unusually mild winter weather. The adjusted net profit for the first half of 2007 was euro 250 million, down euro 7 million. Special charges excluded from the adjusted operating profit concerned mainly environmental provisions and a risk provision related to an ongoing antitrust proceeding against European authorities (for a total charge of euro 72 million).

Second quarter In the second quarter of 2007 refining throughputs on Eni’s own account (9.32 mmtonnes) were stable as compared to the second quarter of 2006, taking into account expiration of a processing contract at the Priolo refinery owned by third parties occurred at the end of 2006 (down 165 ktonnes in the second quarter, down 660 ktonnes in the first half). Refining throughputs in Italy increased by 2% on a homogeneous basis as a result of better performance at the Sannazzaro refinery due to the circumstance that the catalytic cracking unit was shut down for maintenance in 2006. Outside Italy, own throughput declined by 6.1% due to the standstill of a refinery in Germany. In the second quarter of 2007 sales of refined products decreased by 530 ktonnes to 12.02 mmtonnes, down 4.2%, due mainly to lower volumes marketed on wholesale markets in Italy. Volumes of refined products marketed on the retail market in Italy were stable at 2.19 mmtonnes, despite the decline in domestic consumption, boasted by Eni’s marketing initiatives. Gasoline sales declined, while diesel fuel sales increased driven by ongoing trends in vehicle substitution. Retail market share in Italy declined slightly from 29.2% in the second quarter of 2006 to 29.1%. Average throughput (0.63 mmliters in the second quarter of 2007) is in line with the same period in 2006. Volumes marketed on retail markets in the Rest of Europe increased by 40 ktonnes to 0.99 mmtonnes, or 4.2%, mainly in Spain, Switzerland and Germany. Market share in the Rest of Europe grew slightly from 3% in the second quarter of 2006 to 3.1% in the second quarter of 2007. Average throughput (0.65 mmliters in the second quarter of 2007) increased by approximately 90 kliters from the same period in 2006.

ENI REPORT ON THE SECOND QUARTER OF 2007

Sales in the wholesale market in Italy decreased by 90 ktonnes from the second quarter of 2006, to 2.66 mmtonnes, down 8.3%, due to lower demand for heating oil particularly from the power generation sector. First half In the first half of 2007 refining throughputs on Eni’s own account (18.32 mmtonnes) increased by 310 ktonnes, or 1.7%. Refining throughputs in Italy increased by 7.3% to 16.18 mmtonnes, on a homogeneous basis, as a result of higher volumes at the Livorno and Sannazzaro refineries reflecting lower downtime. In the first half of 2007, sales of refined products decreased by 510 ktonnes from the first half of 2006, to 24.36 mmtonnes, down 2.1%, due to lower volumes marketed on wholesale markets in Italy, and lower volumes sold to the petrochemical sector reflecting expiration of a processing contract at the Priolo refinery, partly offset by higher volumes sold to oil companies and traders in Italy. Sales of refined products on the retail market in Italy were 4.17 mmtonnes, a 90 ktonnes decline, or 2.1%, due to competitive pressure. Retail market share in Italy declined by 0.4 percentage points from 29.2% in the first half of 2006 to 28.8% in the first half of 2007. Average throughput (1.18 mmliters in the first half of 2007) declined by about 20 kliters. Sales in the retail market in the Rest of Europe increased by 70 ktonnes to 1.89 mmtonnes, up 3.8%, mainly in Spain and Germany. Market share in the Rest of Europegrew slightly from 3.1% in the first half of 2006 to 3.2% in the first half of 2007. Average throughput (1.23 mmliters in the first half of 2007) increased by approximately 100 kliters from the same period in 2006. Sales in the wholesale market in Italy decreased by 570 ktonnes to 5.27 mmtonnes, down 9.8%, due to lower demand for heating oil from the power generation sector and unusually mild winter weather conditions that impacted sales of heating products (diesel oil and LPG). Sales on the wholesale market in the Rest of Europe increased by 10 ktonnes, to 2.07 mmtonnes, or 1%, essentially in the Czech Republic.

(ii) polyethylene (up 9.4%) and styrene (up 9%) due to positive demand trends. Petrochemical production (2,181 ktonnes) increased by 542 ktonnes from the second quarter of 2006, up 33.1% due to the consolidation of operations at Porto Torres (up 332 ktonnes) and the fact that production and sales of the second quarter of 2006 were by an accident occurred at the Priolo refinery in April 2006. Excluding these effects, production increased by 45 ktonnes (up 3%) due in particular to the growth registered at the Gela, Ravenna and Brindisi plants. First half Sales of petrochemical products (2,812 ktonnes) increased by 132 ktonnes from the first half of 2006, up 4.9%, essentially in olefins due to higher product availability as a consequence of the purchase of the Porto Torres plant from Syndial and to the fact that the second quarter of 2006 were hit by an accident occurred at the Priolo refinery in April 2006. Higher sales were registered in (i) styrenes (up 6.8%) and elastomers (up 3.6%) the latter including also sales of nitrilic rubber from Porto Torres. Petrochemical production (4,411 ktonnes) increased by 857 ktonnes from the first half of 2006, up 24.1% due to the consolidation of operations at Porto Torres (up 615 ktonnes) and the fact that production and sales of the second quarter of 2006 were hit by an accident occurred at the Priolo refinery in April 2006.

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