In addition, Eni's management may make forward-looking statements orally to analysts, investors, representatives of the media and others. In particular, among other statements, certain statements with regard to management objectives, trends in results of operations, margins, costs, return on capital, risk management and competition are forward looking in nature. Words such as 'expects', 'anticipates', 'targets', 'goals', 'projects', 'intends', 'plans', 'believes', 'seeks', 'estimates', variations of such words, and similar expressions are intended to identify such forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and assumptions that are difficult to predict because they relate to events and depend on circumstances that will occur in the future. Therefore, Eni's actual results may differ materially and adversely from those expressed or implied in any forwardlooking statements. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in Eni's Annual Reports on Form 20-F filed with the U.S. Securities and Exchange Commission (the "SEC") under the section entitled "Risk factors" and in other sections. These factors include but are not limited to:

• Fluctuations in the prices of crude oil, natural gas, oil products and chemicals;
• Strong competition worldwide to supply energy to the industrial, commercial and residential energy markets;
• Safety, security, environmental and other operational risks, and the costs and risks associated with the requirement to comply with related regulation, including regulation on GHG emissions;
• Risks associated with the exploration and production of oil and natural gas, including the risk that exploration efforts may be unsuccessful and the operational risks associated with development projects;
• Uncertainties in the estimates of natural gas reserves;
• The time and expense required to develop reserves;
• Material disruptions arising from political, social and economic instability, particularly in light of the areas in which Eni operates;
• Risks associated with the trading environment, competition, and demand and supply dynamics in the natural gas market, including the impact under Eni take-or-pay long-term gas supply contracts;
• Laws and regulations related to climate change;
• Risks related to legal proceedings and compliance with anti-corruption legislation;
• Risks arising from potential future acquisitions; and
• Exposure to exchange rate, interest rate and credit risks.

Any forward-looking statements made by or on behalf of Eni speak only as of the date they are made. Eni does not undertake to update forward-looking statements to reflect any changes in Eni's expectations with regard thereto or any changes in events, conditions or circumstances on which any such statement is based. The reader should, however, consult any further disclosures Eni may make in documents it files with or furnishes to the SEC and Consob.
