Letter from the Chairman of the Remuneration Committee ANDREA GEMMA Chairman of the Remuneration Committee Dear Shareholders, 2019 was a particularly demanding year for the Remuneration Committee, actively engaged in consolidating the implementation of policies planned at the beginning of its term and defining, in an increasingly complex world scenario, the policy proposals for the next term. The first half of 2019 was devoted to the verification of 2018 performance and the definition of targets for 2019, while in the second half of the year we started to define the for the definition of new policy proposals which, in line with recent regulatory developments, will apply in the next three-year term, subject to their approval by the Shareholders’ Meeting. Most significantly, the 2020-2023 Remuneration Policy Guidelines, described in the first section of this Report, will for the first time be subject to a binding vote of the Shareholders’ Meeting of 13 May 2020, in compliance with the regulatory changes introduced with the transposition of the second European Shareholders' Rights Directive (Directive (EU) No. 828/17, so-called “SRD II”). As shareholders, you will also be called on to cast an advisory vote on the second section of the Report, illustrating the implementation of the current policy and the remuneration paid in 2019 to Eni’s Directors, Statutory Auditors and other Managers with strategic responsibilities. The Report therefore maintains the structure already adopted in the past, with two main sections, providing, as in previous years, an introductory Summary with some relevant general information, which we hope will guide you to a better understanding of the Policies proposed and implemented. In presenting the first section of the Report, I would like also on behalf of the Board to draw your attention to the particular care given to the description of the link between corporate strategies and the proposed Policy for the remuneration of directors and senior managers. Similarly, in the second section of the Report, great emphasis is given to disclosure of the methods for implementing the Policy in force, with immediate disclosure of the results actually achieved under each plan and remuneration paid during the year. REMUNERATION POLICY GUIDELINES FOR THE NEW TERM On 18 March 2020, the Board of Directors, acting on a proposal of the Remuneration Committee, approved the 2020-2023 Policy Guidelines following an analysis of the regulatory framework, market practices in Italy and abroad as well as remuneration benchmark studies carried out with the support of international advisors. The 2020-2023 Policy Guidelines were also defined by carefully considering the views expressed by the Shareholders with their vote on the 2019 Policy (which received a favourable vote from 96.78% of the participants), who confirmed their significant appreciation for the structure, general criteria and remuneration levels provided for therein. The Committee is therefore proposing to retain the architecture of the current Policy also for the next term, suggesting only a few updates and refinements. In particular, the overall fixed remuneration for the Chairman and CEO will levels not be increased, and the values envisaged in 2019 represent the maximum benchmark for the incoming Board, which after appointment will have to decide the remuneration for the Directors with delegated powers. It is also envisaged that the incentive system for top management and other managers with strategic responsibilities will continue to be structured as a short-term plan with deferral and in a long-term share-based plan. To this end, considering that the last award of the 2017-2019 Plan was approved in 2019, the Board will submit a new 2020-2022 share-based Long-term Incentive Plan for approval by the Shareholders’ Meeting. The new Plan’s conditions will be substantially similar to the previous ones with performance measures revised in strict consistency with Eni’s strategic priorities and in response to investors’ requests, with the introduction of specific performance goals related to environmental sustainability, as described in the first section of the Report and, in greater detail, in the Plan Informative Document available on the Company’s website.

L ETTER FR OM TH E CHAI R MAN OF TH E REMU N ER A TION C OMMITTEE5 Eni R eport on r emuner ation policy and r emuner ation paid 20 20 competence, professionalism and commitment required by the tasks assigned to them, taking due consideration of the size and complexity of Eni. THE CONNECTION OF THE POLICY WITH CORPORATE STRATEGY The Committee actively cooperates in the effective implementation and monitoring of the current strategic transformation, ensuring that the targets assigned to the CEO and management are aligned appropriately with the medium-to-long term priorities defined by the Board of Directors. In recent years, this process has been characterised by a series of actions focused on the transformation of Eni into an integrated Oil&Gas company, through the growth of the Upstream segment, the relaunch of the Mid-Downstream and compliance with rigorous financial discipline that ensures the sustainability of future actions and projects. This path, which has enabled the Company to face a radically changed and challenging market scenario, will be characterised in the next few years by a strong focus on the energy transition, in line with the decarbonisation targets announced to investors. The variable incentive system proposed by the Committee in the 2020-2023 Policy Guidelines supports the achievement of these targets, consistent with the new corporate mission, integrating the United Nations Sustainable Development Goals into the business model. To this end, the Committee has provided for the maintenance of an articulated and balanced framework of complementary targets, aimed at guaranteeing the profitability of the Company as a whole and operating efficiency in traditional business sectors, also reflecting the priorities assigned in the HSE area and the centrality of the commitment to protect the environment and human safety. For the medium-to-long term, the Committee is proposing to introduce in the new 2020-2022 Long-Term Incentive Plan, performance metrics characterised by a significant focus on environmental sustainability and energy transition. Eni’s primary objective is, in fact, to promote the implementation of an energy transition process that can enable us, by deploying concrete solutions, to preserve the environment and create value in the Countries in which we operate, through the decarbonisation path and circular economy initiatives. EXAMINATION OF THE VOTES AND VIEW OF SHAREHOLDERS AND OF THE REFERENCE CONTEXT In carrying out its functions, the Committee further strengthened its dialogue with the market through the promotion, with the support of the relevant Company functions, of a series of structured meetings with leading institutional investors and proxy advisors. These meetings were focused on receiving feedback on the Report presented to the 2019 Shareholders’ Meeting and listening to investors’ expectations for the future. The outcome of these meetings confirms the general appreciation for the structure and features of Eni’s policy and a positive attitude towards the introduction of certain changes to the Long-Term Plan. Also in response to the expectations of our investors, the new 2020-2022 Long-Term Incentive Plan provides for some significant changes, in particular the introduction of a specific enviromental sustainability and energy transition, with a total weight of 35% , as well as pro-rata payment mechanisms of the incentives for the CEO in the event of termination due to expiry of the CEO’s term without reappointment. The Policy for the new term also provides for the inclusion of a further risk mitigation clause in all incentive plans, through ex-ante verification mechanisms of the incentive conditions (the so-called malus cause), in line with the recommendations and policies of a range of investors and proxy advisors.

 Finally, I would like to emphasise that the constant improvement of the Remuneration Policy would not be possible without a continuous engagement process designed to facilitate communication and create a transparent inclusive relationship between the Company and its Shareholders. I personally made myself the guarantor and actor of this process, to underscore the commitment of the Committee, the constant openness to dialogue and the effective consideration of actions to be taken in light of the feedback we receive, in an approach based on continuous improvement of our practices, policies and reporting methods. CONCLUSIONS Dear Shareholders, I wish to thank the Directors Pietro Guindani, Alessandro Lorenzi and Diva Moriani, who shared this experience with me, for their significant contribution and constant attention to the design of balanced and shared solutions. I express my greetings and sincere wishes to the future members of the new Committee, fully aware of the complexity of the challenges awaiting them. I am confident that this Report will once again testify to the constant effort made by the Committee in these years, and, also on behalf of the Board, I thank you in advance for your endorsement and support to the Remuneration Policy proposed for the new term. 2 March 2020 Chairman of the Remuneration Committee

 Executive Summary Eni Remuneration Policy is approved by the Board of Directors, following a proposal by the Remuneration Committee, which is entirely made up of Non-executive, independent Directors. It is defined in accordance with the corporate governance model adopted by the Company as well as with the recommendations of the Italian Corporate Governance Code. Subject to approval by the Shareholders’ Meeting, the Remuneration Policy presented in the first section of this Report provides the Remuneration Policy Guidelines for Directors, Statutory Auditors and other Managers with strategic responsibilities for the 2020-2023 financial years, i.e. coinciding with the new term of Eni’s corporate bodies. On 18 March 2020, the Board of Directors approved the aforementioned Policy Guidelines, acting on a proposal of the Remuneration Committee, following a preliminary analysis of the relevant regulatory framework, as regards in particular new requirements resulting from the transposition of Directive (EU) No. 828/2017 (the “SRD II”), market practices in Italy and abroad as well as remuneration benchmark analysis carried out with the support of international advisors. The 2020-2023 Policy Guidelines were also defined taking into due account the views expressed by the shareholders on the 2019 Policy (which received a favourable vote from 96.78% of the participants), thus retaining the same structure and potential maximum remuneration levels for the Chairman and CEO, as well as for non-executive Directors in relation to their participation in Board Committees. Finally, the 2020-2023 Policy Guidelines also contain, in accordance with the provisions of the law transposing the SRD II, specific recommendations on the remuneration of the Chairman and other members of the Board of Statutory Auditors for the entire duration of their term, to be determined at the Shareholders’ Meeting on the occasion of their appointment.

 Eni R eport on r emuner ation policy and r emuner ation paid 20 20 “We achieved excellent results in 2019, despite a tough period characterised by geopolitical tensions and much less favourable commodity prices than in 2018. The results today reflthe successful strategy we have pursued in recent years, which has seen Eni become more resilient and growing business. In the Upstream in particular, we achieved record production of 1.87 million barrels a day with a reserve replacement ratio of 117%. The results achieved in the Gas & Power and oil Marketing were particularly positive. Refiand Chemicals endured a challenging period, although the results were however mitigated by Eni’s restructuring actions taken in previous years. Finally, during the year we continued to expand our renewables division, while also expanding our “bio-refi business, with production beginning at Gela. These measures underpin our efforts to expand the low carbon profi of our portfolio, in preparation for the strategy which will be pursued in the coming years. In addition to these results, the ongoing diversifi ation of our Upstream growth in Norway and the United Arab Emirates has further bolstered our portfolio, while the purchase of 20% of the reficapacity Ruwais in the Emirates will increase our refiresilience in unfavourable market conditions. Today Eni is a transformed company. Eni has clear growth options and is firobust, with operating cash fl w generation of €12.1 billion, €1 billion higher than capex, of €7.7 billion and shareholder distribution, including the buy-back, of €3.4 billion. Based on these results, the Board of Directors today approved the proposed distribution of a dividend of €0.86 per share, of which €0.43 had already been distributed in September”. (Claudio Descalzi) Adjusted profit Adjusted operating profit was €8.59 billion, decreasing compared with 2018, mainly as a result of the negative scenario and of the loss of control of Eni Norge following the Var Energy operation at the end of 2018. Excluding, on a like-for-like comparison, Eni Norge 2018 result and net of the eff ct of scenario/discount rates and of IFRS 16, the adjusted operating profit increased by 5%. Operating efficiency Hydrocarbon production: achieved a record level of 1.87 million boe/day thanks to the ramp-up of Zohr and projects started in 2018, particularly in Libya, Ghana and Angola, start-ups in Mexico, Norway, Egypt and Algeria as well as increases in Nigeria, Kazakhstan and the United Arab Emirates. Hydrocarbon reserves: 7.3 billion of boe, witih a 117% all-sources replacement rate. Exploration: new discoveries of about 820 million boe, with a unit exploration cost of $1.5/boe. The portfolio of mineral rights expanded as a result of the acquisition of rights to a total of 36,000 square kilometers. Financial efficiency Cash generation before changes in working capital at replacement cost: €12.1 billion, despite a significantly worsening environment. Cash flow about €1 billion greater than net investments (€7.73 billion) and shareholder remuneration (€3.4 billion) in the form of dividends and the stock buyback. Cash neutrality: net investments and dividend covered by cash flow with a $59/barrel Brent scenario ($64/barrel net of IFRS 16 effects); assuming the budget scenario, the cash neutrality came at $50/ barrel ($55/barrel net of IFRS 16 effects). Leverage: excluding IFRS 16 eff cts, leverage was 0.24 at December 31, 2019; (0.36 including IFRS 16 eff cts). Adjusted ROACE: 5.26%.

JANUARY – MARCH APRIL – JUNE In the first part of 2019, in implementation of the recommendations of the Corporate Governance Code, the Committee conducted its ongoing review of Remuneration Policy, as implemented in 2018, also with a view to developing new Policy proposals for 2019, electing to maintain the structure and the remuneration criteria for Directors and Managers with strategic responsibilities established in 2017 for the entire term, with special regard to the introduction of a new and generally simplified variable incentive system, as discussed in greater detail in the 2017 Remuneration Report. The Committee then analysed Eni’s 2019 Remuneration Report for the purpose of subsequent approval by the Board and presentation to the shareholders and, in a dedicated session, examined the results of the 2019 Shareholders’ Meeting as compared with the results of the leading Italian and European corporations and with those of the companies within the relevant Peer Group. Still in the autumn of 2019, the Committee periodically monitored developments in the legislative framework and market standards concerning the reporting of remuneration-related information, with a specific focus on changes introduced with Legislative Decree no. 49/2019, transposing the SRD II, including a binding vote of the Shareholders’ Meeting on the Remuneration policy described in the first section of this Report, and an advisory vote on the second section concerning remuneration paid during the reporting period. The Committee was also informed of the consultation launched by Consob concerning regulatory changes to contents of the Report and on voting policies issued for 2020 by a number of leading institutional investors and proxy advisors. During the current year, in addition to the ordinary activities set for its annual cycle, the Committee will continue to study the content and implementing measures of SRD II and will also begin ordinary review activities related to the end of the term and subsequent appointment of the new corporate bodies. Compensation With regard to issues concerning the implementation of remuneration policies in light of the criteria approved for the entire term, in 2019 the Committee performed the following activities: verification of the company’s 2018 results for the purpose of implementing the Short and Long-Term variable incentive plans, using a predetermined gap analysis method approved by the Committee in order to neutralise the positive or negative impact of exogenous factors and enable the objective assessment of the performance achieved; definition of 2019 performance targets relevant to the variable incentive plans; definition of proposals for the implementation of the Short-Term Incentive Plan with Deferral for the Chief Executive Officer and General Manager; finalising the proposal (2019 grant) for the implementation of the 2017-2019 Long-Term Share Incentive Plan for the Chief Executive Officer and General Manager and for key management personnel; finalising the proposal on the exercise of the option to activate the non-compete agreement entered into with the Chief Executive Officer and General Manager, as set out in the 2019 Remuneration Report15. 2019 Remuneration Report, Section I, 2019 Remuneration Policy Guidelines, Chief Executive Officer and General Manager, note no.34 (page 29)

At least one member of the Board of Statutory Auditors participated in each meeting, while the Chairman of the Board of Statutory Auditors attended all meetings. At the invitation of the Chairman of the Committee, Managers of the Company and external advisors participated in specific meetings, to provide information and clarifications requested by the Committee to pursue the analysis conducted.

During this year, in addition to the usual activities provided for in its annual plan, the Committee completed preliminary work for the definition of Policy proposals for the new 2020-2023 board term and the new Long-term Equity Incentive Plan for the Chief Executive Officer and key management personnel, as set out in more detail in the first section of this Report16. Following the appointment of corporate bodies, the Committee will also be called to formulate proposals on the remuneration of Directors with powers and Non-Executive Directors for participation in Board Committees, to be submitted for approval by the Board of Directors, subject to a non-binding opinion of the Board of Statutory Auditors, in accordance with the recommendations of the Corporate Governance Code (art.6.C.5) and applicable regulations and the By-laws. Engagement As part of its ongoing monitoring of the positions of institutional investors and leading proxy advisors on remuneration issues, during 2019, the Committee performed the following activities: review of the outcome of the meetings conducted with main institutional investors and proxy advisors, before the 2019 Shareholders’ Meeting, in order to maximise shareholder consensus on the 2019 Remuneration Policy. These meetings were also attended by the Chairman of the Committee, underscoring the importance the Committee attributes to shareholder dialogue; risk and scenario assessment activities, examination of the composition of shareholders, including assessment of the characteristics of the retail shareholder segment, as well as examination of voting recommendations issued by leading proxy advisors and of related voting projections, which were performed with the supporting of a leading consulting firm; start of further extensive dialogue with a broad range of investors in the run-up to the annual meeting, with a view to promoting participation and support for the Eni Remuneration Policy. In the second half of the year, the Committee examined the general criteria for defining the 2020 engagement plan by conducting a preliminary analysis and segmentation of the institutional investors that attended the 2019 Shareholders’ Meeting, while taking account, for target-setting purposes, of parameters related to the materiality of the interest held in the Company and the vote expressed at the most recent meetings. The Committee also assessed the advisability of keeping an open channel of communication with the main proxy advisors given the role they play and their significant influence on how investors vote, particularly as concerns those who have highly diversified portfolios with numerous foreign investments, in accordance with the indications of the recent SHRD II Directive. During the current year, the Committee will move ahead with the implementation of the 2020 plan, with the goal of promoting investor participation and engagement in the Shareholders’ Meeting scheduled for 13 May, which for the first time will be called on to express a binding vote on the criteria and principles applied to the remuneration of Directors. See the section Remuneration Policy Guidelines for the 2020-2023 term.

 Adoption of comprehensive engagement strategy: Periodic cycles of meetings Shareholders’ meetings Ongoing updating of information available on the website ENGAGEMENT ON REMUNERATION POLICY At Eni, we develop interaction with our shareholders and institutional investors regarding remuneration policies, since we are aware of the importance of involving shareholders in the process of defining and monitoring the actual implementation of the Remuneration Policy for Directors and Managers with strategic responsibilities, also as recognised by lawmakers when transposing the guidelines contained in the SRD II. In this context, the analysis of the shareholders’ vote carried out by Eni since 2012 plays an important role, since it focuses particular attention on the voting trends of minority shareholders and the evolution of their positions over time. This activity is performed through a number of communication channels, including: the organisation of periodic meetings and conference calls; the Shareholders’ Meeting as a concluding assessment of past interactions; and the provision of comprehensive, detailed information on our website. Dialogue with our leading institutional investors and proxy advisors is ensured, first and foremost, with the definition of a detailed engagement plan, which is implemented annually by the Compensation & Benefits and Investor Relations functions in support of the policy proposals to be submitted for approval by the shareholders. The Committee is kept constantly informed of activities aimed at defining and implementing the annual engagement plan. The outcome of meetings is monitored, and the feedback received is analysed in order to provide clarification and verify the resolution of any potentially critical issues. The Chairman of the Committee, in coordination with the Chairman of the Board of Directors, may attend the meetings in order to underscore the importance of direct communication with the market in relation to issues relevant to the Committee. In compliance with the Corporate Governance Code (Article 6 – Comments), the Committee also reports on its procedures at the annual Shareholders’ Meeting by way of the Committee Chairman or other duly designated member. SEPTEMBER - DECEMBER JANUARY-APRIL MAY - JULY Definition of Annual Engagement Plan 1st round of meetings with leading institutional investors and proxy advisors Monitoring and scenario analyisis (regulatory framework, voting policies, best practices) Assessment of the outcomes of engagement activities 2nd round of meetings with leading institutional investors and proxy advisors Assessement of the outcomes of engagement activities Examination of voting recommendations of proxy advisors Voting projections Shareholders’ Meeting: presentation of planned Remuneration policy Benchmark analysis of the results of the vote of the Shareholders’ Meeting with focus on the institutional investors’ position Engagement Policy consistent with recommendations of Corporate Governance Code REMUNERATION POLICY APPROVAL PROCESS AND MAJOR CHANGES PLANNED FOR 2020-2023 In the exercise of its powers, the Remuneration Committee defined the structure and contents of the Remuneration Policy for the purpose of preparing this Report, specifically at meetings held on 20 January, 19 February and 2 March 2020, in accordance with the recommendations of the Corporate Governance Code. In taking its decisions, the Committee reviewed the appropriateness, overall consistency and effective implementation of the 2019 Policy Guidelines. The Committee also considered comparative remuneration studies prepared by independent international consultants (Mercer, Willis Towers Watson and Korn Ferry-Hay Group), in the preliminary analysis for the new Remuneration Policy proposals, that basically confirmed a prudent positioning with respect to the benchmark panel. https://www.eni.com/en_IT/about-us/governance/remuneration-report.page

 In preparing this Report, it also considered changes in the regulatory framework, more specifically as related to the transposition of the SRD II into Italian law, as well as national and international standards for the preparation of the Remuneration Report. Finally, following the meetings held during the first engagement cycle with leading institutional investors and proxy advisors, the Committee received a general appreciation of the structure and the remuneration levels provided for by the previous Remuneration Policy. Consequently, with a view to designing the Policy Guidelines for the new term, the Committee proposed to implement the following guidance: maximum remuneration levels for top managers in line with those in force for the previous term, with no increases in fixed remuneration, to be defined by the new Board on the basis of the actual delegated powers and profiles, and the skills/experience of the designated managers, within the limits specified in the Guidelines presented in this Report; structure of Eni’s remuneration policy in line with that previously in force, which provides for two variable incentive plans, a Short-Term Plan with deferral and a Long-Term, Incentive Plan for managers with the greatest impact on company performance. The new share-based 2020-2023 Incentive Plan provides for the introduction of absolute targets specifically related to the decarbonisation process and the energy transition, also in response to the significant interest expressed by investors for sustainability and environmental issues. The new Plan also provides for the application of pro-rata payment mechanisms for the incentives for the CEO in the event of termination related to the expiry of the term of office with no reappointment. Other significant changes in the 2020 -2023 Policy include: the inclusion in existing risk mitigation clauses of specific “malus” conditions, aimed at ensuring ex ante verification of conditions for the payment and/or award of variable incentives; the provision, in line with the law transposing the SDR II, of specific recommendations on the remuneration of members of the Board of Statutory Auditors, to be specifically determined by the Shareholders, who will vote the composition and appointment of this Board on 13 May. The 2020-2023 Eni Remuneration Policy for Directors Statutory Auditors and other Managers with strategic responsibilities was approved by the Board of Directors, acting on a proposal of the Remuneration Committee, at its meeting of 18 March 2020, alongside approval of this Report. In line with the provisions of the law18, PricewaterhouseCoopers, the Audit Firm in charge of the independent audit of the financial statements, verified the preparation of the second section of this Report. The implementation of remuneration policies defined in accordance with the Policy approved by the Shareholders is carried out by corporate bodies delegated to do so, with the support of the competent corporate functions. The 2020-2023 Policy does not allow for exceptions in the implementation phase. Any future revision needs will therefore be submitted by the Board, acting on a proposal of the Remuneration Committee, for approval by the Shareholders’ Meeting. Eni R eport on r emuner ation policy and r emuner ation paid 20 20 2020-2023: Guidelines main changes Purpose and general principles of the Remuneration Policy PURPOSE The Eni Remuneration Policy contributes to achieving the Company’s strategies, long-term interests and sustainability and is defined in accordance with the governance model adopted by the Company and the recommendations of the Italian Corporate Governance Code (referred to below in the main implementation principles and criteria19). In particular, providing that: the remuneration of Directors and Managers with strategic responsibilities is sufficient to attract, motivate and retain individuals of high professional and managerial standing (Art. 6.P.1), as well ensuring the alignment of management interests with the primary goal of creating value for shareholders over the medium to long term (Art. 6.P.2); Art.123-ter, 8-bis, of Consolidated Law on Financial Intermediation, as amended by Art. 3 of Italian Legislative Decree 49/19. With reference to the July 2018 version of the Code (as referred to in the Foreword to this Report, on page 7). The Report also points out when adopted practices comply with the new recommendations included in the most recent revision of the Code, approved on January 2020. Consistent with Company’s strategies and governance model, and recommendations of the Italian Corporate Governance Code

 General goals Promoting Company’s values Recognising roles, respnsibilities and results Sustainable incentives in the long term consistent with the Strategic Plan No variable remuneration for Non-Executive Directors Pay setting and salary-review processes anchored to relevant market benchmarks the remuneration of Non-Executive Directors is commensurate with the competence, professional skills and commitment required by the tasks within the Board of Directors and Board Committees20; the remuneration of members of the Board of Statutory Auditors is commensurate with the competence, professional skills and commitment required, the importance of the office as well as the Company’s size and industry (art.8.C.4)21. Eni’s Remuneration Policy contributes to achieving the Company’s mission by: promoting actions and behaviours reflecting the Company’s values and culture, consistent with the principles of plurality, equal opportunity, non-discrimination, enhancement of individuals’ knowledge and skills, fairness and integrity, as described in the Code of Ethics22 and Eni Policy “Our people”23; recognising roles and responsibilities, results, and the quality of professional contribution, taking into account the operating environment and relevant market pay scales; defining incentive structures tied to the achievement of financial, business, environmental and social sustainability goals, operational and individual objectives, defined with a view to the achievement of long-term business performance, in line with the guidelines of the Strategic Plan and taking account of the interests of all stakeholders. GENERAL PRINCIPLES In pursuing the above, the remuneration of Directors and key executives is defined in line with the following principles and criteria: STRUCTURE OF EXECUTIVE REMUNERATION The remuneration package is appropriately balanced between a fixed and a variable component, in relation to the strategic objectives and the risk management policy of the Company, taking due account of the risk profile of the business (Art. 6.C.1.a). Executive roles with the greatest influence on business performance are characterised by variable remuneration containing a significant percentage of incentive components, particularly long-term awards (Art. 6.P.2). The vesting period and/or incentive deferral period are defined over a period of at least three years, in line with the long-term nature of the business activities performed and with the associated risk profile (Art. 6.C.1.e). REMUNERATION OF NON-EXECUTIVE DIRECTORS Remuneration is commensurate with the competence, professional qualification and effort required for participation on Board Committees set up in accordance with the Articles of Association (Art. 6.P.2); appropriate differentiation between the remuneration afforded to Committee Chairmen, and that of other Committee Members, considering the different roles respectively held regarding coordination of work and relationships with Corporate bodies and functions; Non-Executive Directors are not beneficiaries of variable incentive plans, including equity-based ones, unless decided otherwise by the Shareholders’ Meeting (art. 6.C.4). REMUNERATION OF THE MEMBERS OF THE BOARD OF STATUTORY AUDITORS Remuneration is commensurate with the role played and competence, professional qualification and effort required for participation in the meetings of the Board and Board Committees, taking account of relevant market benchmarks at the national level, appropriately differentiating between the remuneration of the Chairman and that of other Auditors, considering the coordination and and relationships with other Corporate bodies and functions performed by the Chairman. MARKET REFERENCES Total remuneration packages aim for consistency with standard market values applicable for positions or roles of similar level of responsibility and complexity, based on panels of relevant comparators that were developed through benchmarking analysis carried out by international remuneration advisors. In this respect, Eni Remuneration Policy reflects the recommendations of the Italian Corporate Governance Code, in the version approved on January 2020 (point 29). In this respect, Eni Remuneration Policy reflects the recommendations of the Italian Corporate Governance Code, in the version approved on January 2020 (point 30).

Policy approved by the Board of Directors on 28 July 2010.

 Eni R eport on r emuner ation policy and r emuner ation paid 20 20 The fixed component is consistent with role and/or responsibilities, as well as adequate in the event of non-payment of the variable component (Art. 6.C.1.c). VARIABLE REMUNERATION The variable component in defined within maximum limits (Art. 6.C.1.b), and is aimed at aligning remuneration with performance. INCENTIVE TARGETS AND SUSTAINABILITY OF RESULTS Financial and non-financial targets related to short-and long-term variable remuneration, including equity-based compensation, are defined in a manner consistent with the four-year Strategic Plan and with the expectations of shareholders, in order to foster a strong results-oriented focus and combine operational and financial soundness with social and environmental sustainability. Targets are defined in advance, measurable and mutually complementary in order to fully capture the priorities that underpin the Company’s overall performance (art.6.C.1 letter d). These targets are defined so as to ensure: annual performance assessment, on the basis of a balanced scorecard that values the overall business and individual performance, defined in relation to targets specific to each area of responsibility, and for those in charge of internal audit responsibilities, in line with their specific assigned role (Art. 6.C.3); the definition of long-term incentive plans that allow Company performance to be evaluated both in absolute terms, i.e. based on the capacity to generate sustained growth in profitability, and in relative terms compared with a Peer Group, by way of a ranking against Eni’s main international competitors. SHARE-BASED COMPENSATION PLANS Share-based compensation plans are designed to ensure alignment with shareholders expectations over the medium to long term, by way of: three-year vesting periods, linkage with pre-determined and measurable performance targets, the provision of a withholding period that applies to a proportion of share awards (Art. 6.C.2). VERIFICATION OF RESULTS Incentive awards linked to variable remuneration are made pursuant to a detailed verification process that assesses performance against assigned targets, net of the effects of exogenous variables24, on the basis of a variance analysis methodology approved by the Committee, in order to recognise actual value-added attributable to managerial actions. RISK MITIGATION CLAUSES The adoption, with specific rules approved by the Board of Directors, acting on a proposal of the Remuneration Committee, of mechanisms that, on conditions determined and expressly referred to in the Plan Regulations, provide for: the restitution of the variable component of remuneration, if already paid and/or granted (clawback); the withholding/withdrawal of the variable components of remuneration, already vested but not yet paid and/or granted (malus). These mechanisms shall apply in cases when the incentives (or the rights thereto) have vested based on data that subsequently proved to be manifestly misstated (Art. 6.C.1.f) or in cases of wilful alteration of the same data. The same mechanisms shall apply in cases of termination for disciplinary reasons, including serious and intentional violations of law and/or regulations, the Code of Ethics or Company rules, without prejudice to any action allowed under law for the protection of the Company’s interests. The Policy provides that the activation of recoupment claims (or withdrawal of incentives awarded but not yet paid) must take place, once appropriate verification has been completed, within three years of payment (or award) in cases of error, and within fi e years in cases of deliberate intent to defraud. Exogenous variables are those events that, due to their nature or though Company choice, are not under the control of the managers, such as, for example, Oil & Gas prices or the euro/dollar exchange rate.

 Pension and social security benefits Severance indemnities and non-compete agreements consistent with remuneration received and results achieved NON-MONETARY BENEFITS Non-monetary benefits are determined in line with relevant market comparators, consistent with local regulation, in order to complete and enhance the overall remuneration package, taking account of the roles and/or responsibilities, and allowing for relevant social security and insurance components. SEVERANCE INDEMNITIES AND NON-COMPETE AGREEMENTS To the extent that additional payments may be awarded upon termination of employment and/ or term of offi e for executive roles, and that non-compete agreements may apply for roles at greater risk of “poaching”, these are defi ed in terms of either a maximum amount or number of years of remuneration, in line with the remuneration received and the performance achieved, as per recommendations set forth in the implementation criteria (Art. 6.C.1.g) of the Corporate Governance Code. Remuneration Policy Guidelines for the 2020-2023 term Criteria for definition of the Policy: regulatory provisions market advice benchmark studies Linking short and long term incentive system to strategic Plan Short term Objectives Long term Objectives CRITERIA FOR DEFINITION OF THE POLICY This section contains the Remuneration Policy criteria for 2020-2023 term as defi ed by the Board of Directors of 18 March 2020 for Directors, Statutory Auditors and Managers with strategic responsibilities. As mentioned in the Foreword to this Report, the Remuneration Policy, as approved by the Shareholders’ meeting, will apply for a period of three years coinciding with the duration of the new term, and its effects will be limited to the remuneration of the Directors to be appointed by the Shareholders’ Meeting of 13 May 2020. The Remuneration Policy Guidelines 2017-2020 and the related resolutions on remuneration taken by the Board of Directors will continue to apply to Directors in office at the date of the same Shareholders’ Meeting25. The Remuneration Policy Guidelines for Directors for the 2020-2023 term have been defined on the basis of regulatory provisions and the advice of institutional investors and proxy advisors, taking into account the opinion expressed by the 2019 Shareholders’ Meeting (96.78% of voters), as well as the results of benchmarks studies. Therefore, the proposed Guidelines for the 2020-2023 term were developed by providing a maximum potential remuneration, equal to that established for the 2017-2020 term, which the new Board of Directors will be able to adjust on the basis of the business scenario and the characteristics of potential candidates. CONNECTION WITH CORPORATE STRATEGY Remuneration policies support achievement of the targets set in the Company’s Strategic Plan by promoting, through a balanced use of variable incentives and performance measures in the short and long-term incentive systems, the alignment of senior management’s interests with the priority of creating sustainable value for shareholders and other stakeholders, over the medium to long term. The pillars of the Company’s strategy include long-term value creation, attention to the environment, safety and people, strict financial discipline, together with a strong commitment to the ongoing decarbonisation process; they guide the management activity, which is assessed: in a short-term term horizon, in relation to a comprehensive and balanced framework of complementary targets, aimed at ensuring the profitability of the company as a whole and operational efficiency in traditional business sectors, the protection of the environment and human safety and the financial solidity; in the medium-to-long-term horizon, with reference to stock performance (TSR) and generated value (NPV of proven reserves), assessed in relative terms with respect to peers, as well as, starting with the new share-based Incentive Plan 2020-2022, in relation to a series of results measured in absolute terms and characterized by a significant focus on the decarbonisation process, the energy transition and circular economy. For further information, please refer to the 2019 Remuneration Report on the Company’s website (www.eni.com).

 MARKET BENCHMARKS AND PEER GROUP For the Chief Executive Officer, the positioning of the Company’s remuneration is assessed by comparing similar roles only within the international Oil & Gas industry, with regard to upstream activities in particular and in line with the Company’s strategy to increase its focus on this segment of the business. The median value of the remuneration of the Chief Executive Officer is also adjusted for differences in capitalisation of the Companies compared with Eni. The comparator group includes 10 listed companies, which are Eni’s competitors at the international level and possess comparable business characteristics, with regard to operations and geographical areas of interest, while taking account of median corporate dimensions (in terms of capitalization, reserves, output): Apache, BP, Chevron, ConocoPhillips, Equinor ExxonMobil, Marathon Oil, Occidental (replacing Anadarko following the merger), Shell and Total. In line with this approach these companies also make up the Peer Group used for the relative comparison of Eni’s performance under the new Long-Term Share Incentive Plan. Accordingly, the selection criteria required consideration only of those companies that publish data on the NPV of proven reserves that are comparable with Eni, using the calculation method defined by the SEC. For the Chairman and the Non-Executive Directors, the positioning of remuneration is assessed by comparing similar roles in the Top Italy group, which is composed of the main companies listed on the FTSE MIB (Assicurazioni Generali, Atlantia, Enel, Intesa Sanpaolo, Leonardo, Mediaset, Mediobanca, Poste Italiane, Prysmian, Snam, Terna, TIM, Unicredit). For Managers with strategic responsibilities, the positioning of remuneration is assessed by comparing roles of the same level of managerial complexity and responsibility within industrial corporations in national and international markets. Comparisons of remuneration have been conducted with the help of the advisory firms Mercer, Willis Towers Watson, and Korn Ferry-Hay Group. Eni R eport on r emuner ation policy and r emuner ation paid 20 20 Chairman and Non-Executive Directors Managers with strategic responsbilities Officers covered by the Policy CHAIRMAN OF THE BOARD OF DIRECTORS The 2020-2023 Remuneration Policy Guidelines for the Chairman call for a total fixed remuneration of €500,000 gross, including annual remuneration for the powers granted and emoluments as approved by the Shareholders’ Meeting. The remuneration for powers may eventually be adjusted by the new Board based on the actual powers granted26 and professional qualifications, taking account of remuneration benchmarks and compensation approved by Shareholders for the office. There is also a life insurance policy and an insurance policy against permanent disability due to injury or illness contracted in the workplace or elsewhere. No specific severance payments are provided, nor do any agreements exist for indemnities in the case of resignation or early termination of office27. NON-EXECUTIVE DIRECTORS The 2020-2023 Remuneration Policy Guidelines for Non-Executive Directors and/or independent Directors provide for the maintenance of the additional annual remuneration28 provided for in the 2017-2020 term for participating on Board Committees; this can be adjusted following a change in the structure and number of Board committees and related work, taking account of remuneration benchmarks and the skills and qualifications required for the office: Non-executive powers for the 2017-2020 term, connected with the performance of guarantor duties within the internal control system, managing the relationship between the head of the Internal Audit Unit and the Board. The Chairman also performs the representation duties set out in the By-laws, managing the Company’s institutional relations in Italy in coordination with the Chief Operating Officer. n consideration of the referral to this Report, in the 2019 Report on Corporate Governance and Ownership Structure, which is available in the Corporate Governance section of the Company’s website, this information is being published in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Financial Intermediation (agreements between companies and directors, members of the control body or supervisory council which envisage indemnities in the event of resignation or dismissal without just cause, or if their employment contract should terminate as the result of a takeover bid). This remuneration supplements that to be approved by the shareholders on May 13, 2020 for Directors in the amount of €80,000 gross per year in the 2017-2020 term. Fixed remuneration Remuneration for participating on Board Committees

 for the Control and Risk Committees, remuneration of €70,000 for the Chairman and €50,000 for other members; for the Remuneration Committee and the Sustainability and Scenarios Committee, remuneration of €50,000 for the Chairman and €35,000 for other members; for the Nomination Committee, remuneration of €40,000 for the Chairman and €30,000 for other members. No specific severance payments are provided for Non-Executive Directors, nor do any agreements exist for indemnities in the case of resignation or early termination of office29. BOARD OF STATUTORY AUDITORS New rules provide that the Remuneration Policy should also define the criteria for setting the remuneration for the Board of Statutory Auditors (pertaining to the Shareholders Meeting, pursuant to Art.2402 of the Italia Civil Code). Remuneration should take into account the committement (in terms of number and average duration of meetings), the know-how and qualifications required for the office, besides remuneration benchmarks in leading listed Italian companies. Given that Eni is listed in the New York Stock Exchange, it is advisable to consider an increase in the remuneration amount for the 2020-2023 term, taking into account the activites carried out within the Board of Statutory Auditors and additional tasks to be performed in the capacity as Audit Committee pursuant to SEC regulations. Maximum Fixed remuneration unchanged from the previous mandate CHIEF EXECUTIVE OFFICER The 2020-2023 Remuneration Policy Guidelines take the maximum remuneration level provided for in the 2017-2020 term as the maximum potential overall remuneration, allowing for adjustments reflecting strategic challenges and the mix of skills/experience of the designated person, taking into account remuneration benchmarks. FIXED REMUNERATION Fixed Remuneration (FR) for the 2020-2023 term cannot exceed €1,600,000; this maximum level can be decreased in the event of changes of current offices, powers and employment relationships, and also based on the qualifications of the designated person. This remuneration encompasses any emoluments due for participation in the meetings of the boards of directors of other Eni subsidiaries and/or shareholdings. Should the CEO be given the role of General Manager, with the related management relationship, the CEO will also be entitled to receive an allowance for travel, in Italy and abroad, in line with the applicable provisions under the relevant national collective bargaining agreement for senior managers of industrial companies and with supplementary company-level agreements. VARIABLE REMUNERATION: SHORT-TERM INCENTIVES WITH DEFERRAL The guidelines for the new term provide for the maintenance of Short-term Incentive Plan with deferral, as approved by the shareholders on 13 April 2017 within the scope of the Remuneration Policy Guidelines for the 2017-2020 term. Performance Conditions The 2020 Short-term Incentive with deferral is tied to achieving the 2019 targets set by the Board on 18 March 2020. Achievement of the targets is assessed net of any variable, exogenous effects (e.g. oil and gas prices or euro/dollar exchange rates) and in application of a predetermined method of gap analysis as approved by the Remuneration Committee. The 2020 targets approved by the Board on March 2020 for the 2021 short-term variable incentive system with deferral call for maintenance of a structure that is focused on essential milestones in line with the Strategic Plan and balanced in respect of the interests of the various stakeholders. The performance parameters are closely linked to the corporate strategy, as they are intended to Information provided in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Financial Intermediation, as specified under note 24 above.

In this regard, Eni seeks to constantly expand our business, in the upstream segment, by way of a targeted exploration strategy and a dual-exploration model that allows us to quickly monetize reserves, as well as an, organic growth in production generated at particularly competitive cost points. In the mid-downstream segment, reinforcement is pursued by expanding our LNG portfolio and our base of retail customers, while in the downstream segment there is a constant focus on optimising our industrial assets and developing the green business; the upstream indicators of hydrocarbon production and exploration resources measure the operating efficiency of a strategy centred around the continuous replacement of the portfolio of resources and taking full advantage of that portfolio by way of a “dual-exploration” model and the “fast-track” implementation of discoveries; the indicators of GHG emissions and the Severity Incident Rate (SIR) reflect Eni’s HSE priorities and the central importance of our commitment to protecting the environment and to individual safety. In particular, within the scope of our decarbonization strategy, Eni seeks to: (i) reduce the carbon footprint of our activities, beginning with direct upstream emissions, fugitive emissions, and the elimination of the process gas flaring; (ii) maintain low-carbon portfolio that is resilient in a range of contexts; and (iii) develop green businesses with a constant focus on research. These efforts are consistent with the target set for 2025 as reported to investors. With regard to SIR, prevention and risk minimization are cornerstones of Eni’s operations in our commitment to achieving constant improvements in safety for all workers and to expressing this commitment in the process of assessing the performance of senior management. In particular, use of an SIR focuses Eni’s commitment on reducing serious injuries given that it calculates the frequency of injuries over the number of hours worked, applying increasing weights with the severity of the injury; - the indicators ROACE and debt-to-EBITDA measure the company’s financial discipline and the quality of our financial structure and earnings, which translates into a careful selection of investments, into efficiency and cost control, and into a rapid return on investment. All of these efforts enable us to reinforce our resiliency even during economic downturns. Incentive mechanisms and levels In line with the general Remuneration Policy principles, the STI Plan with deferral features the same characteristics as in the previous term, described below. Each target is predetermined and measured based on a performance scale of 70-150 points (target=100) in relation to the weight assigned to each (a score below 70 points implies a performance multiplier of zero). For purposes of the total incentive award, the minimum overall performance is 85 points. Economic and Financial Results Operating targets and sustainability of economic results Environmental sustainability and human capital Efficency and Financial strength Incentive mechanisms and levels unchanged

 Considering the need to promote business development initiatives, it is also envisaged to reflect portfolio development operations not foreseen in the budget, if the Board of Directors, at the time of their approval, recognizes them as transactions of particular relevance for the purposes of implementing the strategic guidelines of the 2020-2023 Plan and the Remuneration Committee considers them relevant for the purposes of annual performance. In any case, the maximum score of the performance scale cannot exceed 150 points. The total incentive (TI) is calculated using the following formula. Target Where FR is the Fixed Remuneration, “ITarget” is the incentive percentage at target performance level, which is set to 150% of total fixed remuneration for the Chief Executive Officer, and M is the multiplier related to overall performance. CHART 10 - TOTAL INCENTIVE MULTIPLIER Annual Performance Annual Multiplier 100% 85% 7085 100150 budget Annual incentive payable during the year The total incentive is divided in: an Annual Incentive (Iyear) equal to 65% of the total incentive, paid in the year following the year in which the performance was attained. I = IT x 65% The levels of the annual incentive payable, depending on the performance levels achieved, are shown in the table below30. TABLE 5 – LEVELS OF ANNUAL PAYABLE INCENTIVE The Annual Incentive values as a % of fixed remuneration shown in the table were calculated as follows: - Threshold: 83% = 65% x (150% x 85%) - Target: 98% = 65% x (150% x 100%) - Max: 146% = 65% x (150% x 150%)

 VARIABLE REMUNERATION: LONG-TERM SHARE INCENTIVES With regard to the implementation in 2019 of the third and final award of the 2017-2019 LTI share-based Plan, a new 2020-2022 LTI share-based plan has been defined with the same purposes as the previous one, aimed at aligning managers’ activity with stakeholder interest. The new LTI share-based Plan has similar features as the previous one (including the same maximum incentive levels) and was drawn up in accordance with the indications of institutional investors and proxy advisors, and the results of benchmarking with the Eni Peer Group. The Plan provides for three annual awards starting from 2020, each with a three-year vesting period, in accordance with the timeline below. CHART 13 – LTI SHARE-BASED PLAN TIMELINE PERFORMANCE AND VESTING PERIOD YEAR T Award of shares YEAR T+1YEAR T+2YEAR T+3 Granting of shares Objectives of LTI share-based Plan Performance Conditions As to the performance conditions, the relative performance parameters used in the previous plan were integrated with four new absolute parameters assessed over the three-year period, with a view to better balancing the targets in accordance with the stakeholders expectations and supporting the implementation of the Strategic Plan. The targets and related weightings are as follows: 25% Market objective: linked to the Total Shareholder Return (relative) 20% Industrial objective: Net Present Value of proven reserves (relative) 20% Economic-financial objective: organic Free Cash Flow (absolute) 35% Environmental Sustainability and Energy Transition objectives, as follows: 4.1) 15% Decarbonisation objective (absolute): CO2 Emission Intensity (absolute) 10% Energy Transition objective: development of electricity generation from renewables (absolute) 10% Circular Economy objective: Important projects in bio-fuels (absolute) The descriptions of each parameter are given below: The diff rence between the TSR of Eni share and the TSR of the FTSE Mib index of Borsa Italiana, adjusted by the Eni correlation index, compared with the equivalent adjusted TSR measures for each company of the Peer Group, as shown in the following formula (25% weighting): TSR - (TSRx ρ) COIDX CO,IDX Where: TSRCO: TSR of Eni or of one of the companies of the Peer Group; TSRIDX: TSR of the reference stock market index of the company to which TSRco applies; ρCO,IDX: Correlation coefficient between the performance of the shares and the performance of the reference market (FTSE Mib, S&P 500, FTSE 100, CAC 40, AEX, OBX). This indicator was introduced in order to neutralize the potential effects on the performance of each stock of the respective stock market performance. More specifically, this neutralisation is proportionate to the correlation between the stock and the stock market trends over the same three-year period by using the correlation coefficient. Net Present Value (NPV) of proven reserves vs. the Peer Group, measured in terms of the annual unit value ($/boe), with performance calculated as the average annual performance over the three-year period. For the two relative parameters, the reference Peer Group is described in the section “Market References and Peer Group” (Apache, BP, Chevron, ConocoPhillips, Equinor, ExxonMobil, Marathon Oil, Occidental Petroleum, Shell).

 Eni R eport on r emuner ation policy and r emuner ation paid 20 20 Development of electricity generation from renewable resources, measured in terms of megawatt of installed capacity at the end of the three-year performance period, compared with the same value expected in the 3rd year of the Strategic Plan approved by the Board of Directors in the year of award and kept unchanged in the performance period. Decarbonisation objective, measured as the final value of GHG Emission Intensity at the end of the three-year period (tCO2eq/kboe) relating to Eni Upstream operated production, compared with the same value expected in the 3rd year of the Strategic Plan approved by the Board of Directors in the year of award and kept unchanged during the performance period. Circular economy objective, measured in terms of progress of three important projects in biofuels compared with the progress expected in the 3rd year of the Strategic Plan approved by the Board of Directors in the year of award and kept unchanged in the performance period. Further details on the methods for defining and verifying the objectives and the related threshold, target and maximum performance levels are given in the Information Document on the Plan, prepared in accordance with Consob regulations for approval by the Shareholders’ Meeting and published on the Company website. Incentive mechanisms and levels The annual award of shares is calculated using the following formula. No. Awarded shares = FR x %I Attr Where FR is the Fixed Remuneration, “ITarget” is the incentive percentage at target performance level, which is set to 150% of total fixed remuneration for the Chief Executive Officer, and PriceAttr is the price of the award calculated as the average of the daily official prices (source: Bloomberg) recorded in the four months before the date of the Board of Directors meeting held annually to approve the plan rules and the award to the Chief Executive Officer. Grantable shares at the end of vesting period are calculated using the following formula: F In which MF is the final multiplier equal to the weighted average of the multipliers of each parameter. For relative parameters (linked to TSR and NPV of proven reserves), each multiplier may be between zero and 180%, with a threshold set at a median level, in accordance with the scale shown below. Performance scale and multiplier TABLE 7 - PERFORMANCE SCALE – MULTIPLIER FOR RELATIVE PARAMETERS Median positioning For absolute parameters (FCF, Decarbonisation, Energy Transition and Circular Economy), performance will be measured based on a partial multiplier between zero and 180% determined as a function of performance, as in the following chart:

 CHART 14 - PERFORMANCE SCALE - MULTIPLIER FOR ABSOLUTE PARAMETERS 200% 180% 160% Partial multiplier 120% 100% 80% 60% 40% 20% 0% 80% Minimum Performance 130% Target Performance 180% Maximum Performance The table below shows the thresholds, targets and maximum monetary value of shares (as a percentage of fixed remuneration) grantable to the Chief Executive Officer at the end of the vesting period, net of the change in share price for the period32. TABLE 8 - VALUE LEVELS OF GRANTABLE SHARES Average 3-year weighted Value of shares The threshold can be exceeded, for example, when the minimum performance level is achieved for all absolute parameters (Free Cash Flow , Decarbonisation, Energy Transition and Circular Economy). Pro-rata mechanism in case of consensual termination of Chief Executive Officer The Plan Rules provide that 50% of the shares assigned at the end of the vesting period shall remain restricted for a period of 1 year from the date of assignment for the Managing Director and Managers in service. In the event of early termination for the Chief Executive Officer, due to resignation and not justified by a substantial reduction in powers or of termination for just cause, all rights to the award and payment of incentives shall lapse. In the event of termination related to expiry of the term of the Board of Directors without renewal, the grant of Eni shares of each award will be prorated with respect to the period of permanence in office, according to the results verified over the same period. NON-MONETARY BENEFITS There is a life insurance policy and an insurance policy against permanent disability due to injury or illness contracted in the workplace or elsewhere. Also provided, as per provisions contained in the national collective bargaining agreement and the supplementary company agreements for Eni senior managers, is enrolment in the supplementary pension plan (FOPDIRE)33 and in the supplementary health plan (FISDE)34 together with a company car for business and personal use. The incentive values as a % of fixed remuneration shown in the table were calculated as follows: - Threshold: 60% = 150% x 40% - Target: 174.75% = 150% x 116.5% - Max: 270% = 150% x 180% Defined-contribution and individual-capitalization contractual pension fund (www.fopdire.it). Fund that reimburses healthcare spending for active or retired senior management and their family members (www.fisde-eni.it).

 PAY MIX The remuneration package for the Chief Executive Officer includes a fixed component, a short-term variable component, and a long-term variable component, which comprises a short-term incentive deferral and long-term share based incentive determined using internationally recognized methodologies for remuneration benchmarks. The pay mix, calculated by considering fixed remuneration as the base, is weighted significantly towards the variable components, with a dominant weighting attributed to the long-term component, as shown in the figure below.

For the General Manager, if appointed: indemnity in the event of the consensual termination of the management relationship, unchanged compared with this term (two years of fi ed remuneration plus short-term incentive), taking due account of the provisions of the appropriate national collective bargaining agreement providing for a maximum of three years of total actual remuneration. Non-compete agreement: During the 2020-2023 term, in order to safeguard the Company’s interests, non-compete agreement may be put in place and will be activated at the sole discretion of the Board through the exercise of an option right, with a fi ed payment determined in relation to the obligations established under the agreement (duration and scope of the restrictions on business activities and countries of operation) up to a maximum, for each year of obligation, equal to fi ed remuneration plus a component determined in line with the average annual performance of the STI Plan over the previous term, varying between €500,000 (target) and €1,000,000 (maximum). The payment for the option right shall not exceed €300,000.

 MANAGERS WITH STRATEGIC RESPONSIBILITIES For Managers with strategic responsibilities, the 2020-2023 Remuneration Policy Guidelines are unchanged on those for the previous term, maintaining remuneration plans that are strictly in line with those of the Chief Executive Offi er, to better guide and align managerial action with the objectives set out in the Company’s Strategic Plan, and with the provisions and protections laid down by national collective bargaining agreement for senior managers. In particular, the Long-Term Share Incentive Plan and Short-Term Variable Incentive Plan with deferral – intended for the Chief Executive Offi er will also apply to Managers with strategic responsibilities. Fixed remuneration differentiated by level of responsibility and complexity of position FIXED REMUNERATION Fixed remuneration is based on roles and responsibilities assigned taking into consideration a graduated and a generally median to below-median positioning versus national and international executive markets for comparable roles. It may be updated periodically, during the annual salary review for all managers. Given current market comparators and trends, the Guidelines provide for a selective approach to salary reviews, while maintaining appropriate levels to ensure competitiveness and motivation. More specifically, proposed actions will include measures to adjust fixed/one-off remuneration for those in positions that have seen a significant increase in responsibility or scope, and to address retention risk and reward excellent performance. In addition, in their capacity as Eni officers, Managers with strategic responsibilities are entitled to receive allowances due for travel in Italy and abroad, in line with applicable provisions of the Italian national collective bargaining agreement for senior managers and supplementary Company agreements. VARIABLE INCENTIVE PLANS Short-term Variable Incentive Plan with deferral The Short-Term Incentive Plan with deferral, already described for the Chief Executive Officer, will be maintained in 2020. The targets set for Managers with strategic responsibilities are consistent with those assigned to the Chief Executive Officer, on the basis of the same balancing of stakeholder interests, in addition to relevant individual targets, consistent with the responsibilities of the role and the provisions of the Company’s Strategic Plan. For Managers with strategic responsibilities, the target incentive levels for the Short-term Variable Incentive Plan differ depending on the role’s level of responsibilities and complexity up to 100% of fixed remuneration, with a maximum incentive level payable for the annual and deferred portions of 98% and 121% of fixed remuneration, respectively. Long-term Variable Incentive Plan Managers with strategic responsibilities participate in the 2020-2023 Long-Term Performance Share Plan. The Plan is directed at managers who are critical for the business and envisages three annual awards, starting in 2020, with the same performance conditions and characteristics as those described above for the Chief Executive Officer. For Managers with strategic responsibilities, the value of the shares to be awarded each year differs depending the level of their role and is limited to a maximum of 75% of fixed remuneration, with the maximum award corresponding to 135% of fixed remuneration, calculated with reference to the grant price of the shares NON-MONETARY BENEFITS In line with national collective bargaining agreement and supplementary Company-level agreements for Eni managers, the Policy Guidelines provide for life and disability insurance cover (due to workplace or other injury or illness), as well as enrolment in the supplementary pension plan (FOPDIRE) and health plan (FISDE), together with a company car for business and personal use, and the possible assignment of housing based on operational and mobility requirements.

 PAY MIX In line with market best practice, as well as the valuation methods used for the Chief Executive Officer, the average target pay mix of the remuneration package for Managers with strategic responsibilities who are eligible for the Short-Term Monetary Plan with deferral and the Long-Term Performance Share Plan features a balance between fixed and variable components that is weighted towards medium-long term variable incentives.

These criteria take into account the position held, statutory retirement age and actual age of the manager at the time employment is terminated and the annual remuneration received. For cases of termination that present high competitive and litigation risks relating to the nature of the position, agreements may contain additional non-compete clauses with payments defined in relation to remuneration level, scope, duration and effectiveness of the agreement.

 Section II – Remuneration and other information Implementation of the 2019 remuneration policies Implementation of the 2019 remuneration policies for Directors and Managers with strategic responsibilities, as verified by the Remuneration Committee in conjunction with its periodic assessment as called for the Corporate Governance Code, was in line with the 2019 Remuneration Policy approved by the Board of Directors on 14 March 2019, taking account of the provisions of the resolutions of the Board of Directors of 13 April 2017 and 19 June 2017 concerning, respectively, remuneration for Non-Executive Directors serving on Board committees and the remuneration of Directors with delegated powers. 2018 PERFORMANCE OUTCOMES FOR THE PURPOSE OF INCENTIVES PAID AND/OR AWARDED IN 2019 This section covers the verification of results for 2018, as approved by the Board of Directors on 14 March and 30 May 2019 for the purpose of incentives earned and payable and/or awardable in 2019 to the Chief Executive Offi er and General Manager and other Managers with strategic responsibilities. SHORT-TERM INCENTIVE (STI) PLAN 2019 The 2019 STI Plan calls for the vesting of an incentive, upon verification of performance levels related to targets set for 2018, divided into a 65% fraction payable in 2019 and a 35% deferred portion that is awardable in 2019 and subject to the performance conditions established in the plan over a three-year vesting period. More specifically, the verified performance related to targets assigned in 2018 to the Chief Executive Officer and General Manager was approved by the Board, based on a recommendation by the Remuneration Committee, on 14 March 2019 and resulted in a performance score of 127 points on the measurement scale used, the target and maximum performance of which are 100 and 150 points, respectively. The table shows the weightings and performance level achieved for each target.

 Eni R eport on r emuner ation policy and r emuner ation paid 20 20 EBT: a significant improvement of performance was achieved by way of reduction of costs, particularly in the upstream sector, and improvements of margins and volumes, in the mid-downstream sector, also thanks to a restructuring of the asset portfolio. Free cash flow: very high level achieved by way of significant improvements in the economic performance, and efforts to optimize working capital. Hydrocarbon production: in spite of high production levels achieved in 2018, given the high targets, this performance was penalised by a decrease in gas demand due to geopolitical and commercial issues in Libya, Venezuela and Ghana as well as unplanned shutdowns in the US, Norway and Nigeria. Exploration resources: exploration resources were added, particularly in Egypt, Cyprus, Norway, Angola, Nigeria, Mexico and Indonesia totalling over 0.6 billion BOE, confirming the focus on exploration activities to ensure organic growth. Severity Incident Rate (SIR) a total recordable incident rate per employee and contractor for millions of worked hours, which weighs injuries on the basis of severity: it increased due to a number of especially severe incidents. CO2 emissions/operated upstream production: this indicator has fallen by 6% compared with 2017 thanks to a reduction in flaring emissions and higher production contribution from projects with lower than portfolio-average emission intensity. ROACE: this performance was achieved by improving performance. Debt/EBITDA: this performance was achieved by improving financial performance. DEFERRED MONETARY INCENTIVE (DMI) PLAN 2015-2017 Payment DMI 2016 The 2015-2017 DMI Plan calls for three annual awards, and for the second of these (2016), on 14 March 2019, the Board of Directors, as verified and recommended by the Remuneration Committee, approved 2018 EBT for Eni at the maximum performance level, resulting in an annual multiplier of 170%. As a result, given the already verified performance levels of 2016 and 2017, the three-year average multiplier, to be applied to incentives awarded in 2016 for payment in 2019, came to 170%. The table below shows the performance levels achieved during the vesting period.

(**) It does not consider Var Energy. The main actions leading to the achievement ot target performance are: EBT: the improvement is mainly due to the optimisation of margins and volumes in the Gas & Power segment and a reduction in financial expense reflecting the performance of strategic liquidity management; Free cash flow: achieved a particularly high level also thanks to lower investments as well as the optimisation of working capital Hydrocarbon production: despite production levels reached in 2019, performance was penalised lower world demand for gas/LNG and by authorization delays in Italy, in a context of high expected targets

 Exploration resources: important exploration resources have been added, mainly in Algeria, Angola, Ghana and Indonesia for more than 0.82 billion boe, confirming the effectiveness of exploration activities to ensure organic growth Severity Incident Rate (SIR) a total recordable incident rate per employee and contractor for millions of worked hours, which weighs injuries on the basis of severity: it increased due to a number of especially severe incidents; CO2 emissions/operated upstream production: the rate decreased by about 9% compared with 2018 owing to the reduction of flaring emissions, important eff rts for reducing natural gas fugitives and higher production contribution from projects with a lower-than-average portfolio emission intensity. ROACE: this performance was achieved by improving performance.. Debt/EBITDA: this performance was achieved by improving financial performance also as a result of investment adjustments. 2015-2017 DEFERRED MONETARY INCENTIVE (DMI) PLAN 2017 DMI vested The 2015-2017 DMI Plan calls for three annual awards, and for the third of these (2017), on 18 March 2020, the Board of Directors, as verified and recommended by the Remuneration Committee, approved the 2019 EBT for Eni at the maximum level, resulting in an annual multiplier of 170%.
