Letter from the Chairman of the Remuneration Committee

Monica de Virgiliis Chair of the Remuneration Committee

The main goal of this Committee is to work on the remuneration systems to ensure that they continue to consistently support the business strategy and creation of value for shareholders.

Dear Shareholders:

As Chair of Snam's Remuneration Committee and together board members Elisabetta Oliveri and Alessandro Tonetti, we are pleased to present to you Snam's Remuneration Report for 2018, which has been prepared with the aim of assuring the Shareholders and Investors maximum transparency in terms of the quality of the remuneration systems adopted by the Company.

As announced in last year's Report, the main goal of this Committee for 2017 was to work on the remuneration systems to ensure that they continue to consistently support the business strategy and creation of value for shareholders. In keeping with this aim, last year saw the introduction of the long-term share-based incentive plan. During the first part of the year, the Committee worked on the plan's design and then, following the plan's approval by the Shareholders' Meeting, focused on its implementation and on the careful definition of the performance targets for the proposed indicators.

During the second part of 2017, the Committee worked on reaching an agreement with regard to the severance pay for the Chief Executive Officer on the basis of the criteria employed for the previous Chief Executive Officer.

Finally, 2017 also saw the customary analysis of the results of the shareholders' meeting. In addition, with the support of the relevant company departments, a series of direct discussions with investors was held. This approach has allowed us to take on board suggestions that will help improve the transparency of the information provided in this Report and has also opened up a new channel of dialogue that will enable us to gather ideas and insights in relation to the setting of the Group's remuneration policy.

Finally, during the first part of 2018, the Committee worked on defining the corporate targets for the year, focusing in particular on the development of new business. In line with 2017, one target related to this area was confirmed, which is focused on initiatives related to Global Solutions, LNG and Digital Innovation. As usual, the second section of the report contains comprehensive information regarding the remuneration measures taken in 2017, which are consistent with the remuneration policy announced that year.

I hope that our work will be judged positively in the advisory vote you are asked to cast on the first section of the report. I would like to thank you in advance for any comments you may wish to make at the Shareholders' Meeting and during any other opportunities for discussion and assure you that In the future, we will continue our strong commitment to ensuring the utmost clarity and transparency.

Governance of the remuneration process

The process of defining the Snam Remuneration policy involves many parties, in line with the regulatory and statutory provisions and with the Company's governance model.

Shareholders' Meeting

With regard to remuneration, the Shareholders' Meeting:

• decides on the pay of members of the Board of Directors, at the time of appointment and for the entire term of office;
• resolves, at the proposal of the Board of Directors, on remuneration plans based on financial instruments;
• takes a non-binding vote on the first section of the Remuneration Report.

Board of Directors

With regard to remuneration, the Board of Directors, in line with the Snam corporate governance system and rules5 :

Meeting and the proposals of the Committee on the adequacy, overall consistency and application of the Remuneration Policy adopted for Directors and Managers with strategic responsibility.

In compliance with the recommendations of the Code of Corporate Governance, the Board of Directors is supported, as far as remuneration is concerned, by a committee of non-executive directors, the majority of whom are independent with proposal and advisory functions (Remuneration Committee). The President is identified among the independent members..

Remuneration Committee Composition, appointment and powers

The Remuneration Committee, first established by the Board of Directors in 2002, is composed, in line with the recommendations of the Code of Corporate Governance, of three non-executive directors, the majority of whom are independent, with the Chairman chosen from the independent directors. At least one member of the Committee has adequate knowledge and experience in financial matters or remuneration policies, as assessed by the Board of Directors at the time of the appointment. On 11 May 2016, the Board of Directors identified the Chair (Monica de Virgiliis) as a member who possesses adequate knowledge and experience of financial issues and remuneration policies.

Since 11 May 2016, the Remuneration has been composed of the following Directors:

Member	Position
Monica de Virgiliis	Independent non-executive director(1) - Chairman
Alessandro Tonetti	Non-executive
Elisabetta Oliveri	Independent non-executive director(1)

(1) Independent pursuant to the independence requirements set out by the TUF and the Code of Corporate Governance.

The Executive Vice President Human Resources & Organization of Snam performs the role of Secretary to the Committee and helps the Chairman in carrying out his/her functions. The composition, tasks and operating methods of the Committee are governed by dedicated regulations⁶ , approved by the Board of Directors and most recently updated on 11 May 2016.

6 The regulations of the Remuneration Committee are available in the "Ethics & Governance" section of the Company's website.

The Committee makes proposals and provides advice to the Board of Directors:

• it submits the Remuneration Report for the approval of the Board of Directors, with particular regard to the remuneration Policy for directors and managers with strategic responsibilities, so that it may be presented to the Shareholders' Meeting called to approve the financial statements within the time limits set by law;
• it reviews the vote on the Remuneration Report taken by the Shareholders' Meeting in the previous financial year and expresses an opinion to the Board of Directors;
• it prepares proposals regarding the remuneration of the Chairman and the Chief Executive Officer, with regard to the various forms of remuneration and salary;
• it makes proposals concerning the remuneration of members of the Board Committees;
• it examines information reported by the CEO and proposes;
• the general criteria for the remuneration of managers with strategic responsibilities;
• general guidelines for the remuneration of other managers of Snam and its Subsidiaries;
• annual and long-term incentive plans, including sharebased plans;
• it proposes the definition of performance targets, the calculation of company results, the definition of claw-back clauses related to the implementation of incentive plans and the determination of the variable remuneration of Directors with powers;
• it proposes the definition, with regard to Directors with powers: i) of the remuneration to be paid in the case of termination of employment; ii) of non-compete agreements;
• it monitors the application of decisions made by the Board;
• it periodically evaluates the adequacy, overall consistency and concrete application of the Policy adopted, expressing proposals to the Board in this regard;
• it performs any duties that may be required by the procedure concerning related-party transactions adopted by the Company;
• it reports on the exercising of its functions to the Shareholders' Meeting convened to approve the separate financial statements for the year, through the Chairman of the Committee or another member appointed by the latter.

In accordance with the Board's decision, the Remuneration Committee also annually reviews the remuneration structure of the Senior Vice President of Internal Audit and ensures that it is consistent with the general criteria approved by the Board for managers, indicating the above to the Chairman of the Control and Risk Committee for the purposes of the opinion which he must express on this matter at the Board meeting.

The Remuneration Committee reports to the Board at least every six months on the activities carried out before the deadline for the approval of the financial statements and the half-year report, at the board meeting indicated by the Chairman of the Board of Directors; in addition, following each meeting, the Committee updates the Board of Directors, at this latter's first available meeting, with regard to the subjects dealt with and the observations, recommendations and opinions formulated.

In addition, the Committee reports on the exercise of its functions to the Shareholders' Meeting called for the approval of the financial statements for the period, via the Chairman of the Committee, in accordance with the provisions of its Regulations, in compliance with the Code of Corporate Governance and with the aim of establishing a dedicated channel of communication with shareholders and investors.

In order to perform its analytical and preliminary functions effectively, the Remuneration Committee makes use of the competent Company structures and can, through the latter, take advantage of the support of external consultants who are not in a position to compromise the independence of the advice.

Cycle of activities of the Remuneration Committee

The activities of the Committee implement an annual programme which breaks down into the following stages:

• verifying the adequacy, overall consistency and concrete application of the Policy adopted in the previous year, with regard to the results achieved and the remuneration benchmarks from highly specialist providers;
• defining the remuneration Policy proposals and the proposals relating to performance targets connected to short- and long-term incentive plans;
• proposals regarding the implementation of existing short- and long-term variable incentive plans, after verifying the results achieved for the performance targets set out in said plans;
• preparing the Remuneration Report to be submitted, annually, following the approval of the Board of Directors, to the Shareholders' Meeting.

Activities planned for 2018

The Committee has scheduled seven meetings for 2018. As at the date of the approval of this Report, the first four meetings concentrating on the following subjects had already been held: regular evaluation of the remuneration policies implemented in 2017 for the purpose of defining the 2018 Policy proposals; modification of the scope of participation in the Long-term share-based Incentive Plan; examination of this Report for later approval by the Board of Directors; final balances of the 2017 company results and definition of the 2018 performance targets for the purpose of the variable incentive plans.

Approval process for the 2018 Remuneration Policy

In exercising its powers, the Remuneration Committee defined the structure and the contents of the Remuneration Policy, for the purpose of preparing this Report, specifically at the meeting of 12 March 2018, in line with the recommendations of the Code of Corporate Governance. In making its decisions, with a view to consistency, the Committee took into account the decisions taken by the Shareholders' Meeting of 27 April 2016 and by the Board of Directors in 2016.

The above-mentioned activities were conducted following an evaluation of the regulatory framework regarding remuneration, as well as of the practices used in the preparation of remuneration reports in a national and international context.

The Snam 2018 Remuneration Policy for Directors and Managers with Strategic Responsibilities was then approved by the Board of Directors, at the recommendation of the Remuneration Committee, at the meeting of 13 March 2018, at the same time as the approval of this Report. The implementation of the remuneration policies defined consistent with the guidelines of the Board of Directors is carried out by the delegated bodies, with the support of the competent corporate functions.

Information on the remuneration of the Directors and management is also ensured through the updating of the pages specially dedicated to these subjects in the "Ethics and Governance" section of the Company's website.

Board of Statutory Auditors

With regard to remuneration, the Board of Statutory Auditors, which regularly attends the meetings of the Remuneration Committee through the Chairman or a Standing Auditor designated by him/her, expresses the opinions required by the applicable law with reference, specifically, to the remuneration of Directors vested with specific duties, pursuant to Article 2389 of the Italian Civil Code, also verifying its consistency with the general policy adopted by the Company.

Aims and general principles of the remuneration policy

The Snam Remuneration Policy is defined in line with the governance model adopted by the Company and with the recommendations of the Code of Corporate Governance, in order to attract and retain people with a high professional and managerial profile and to align the interests of management with the prime objective of creating value for shareholders in the medium-/long-term.

Under the scope of the Policy adopted, the variable component linked to the results achieved, through incentive systems related to achieving economic/financial targets, the development of the business and operations, defined from a perspective of sustainability of results, consistent with the Company's Strategic Plan, takes on particular importance.

Specifically, Snam's Remuneration Policy contributes to the realisation of the mission, corporate values and strategies, through: i) promoting actions and behaviour in line with the culture of the Company, in compliance with the principles of pluralism, equal opportunities, developing peoples' knowledge and professionalism, equality and non-discrimination as set out in the Snam Code of Ethics; ii) recognising the responsibilities assigned, the results achieved and the quality of the professional contribution, taking into account the context and the reference markets applicable for similar offices or positions of a similar level in terms of responsibilities and complexity, under the scope of the corporate panel comparable with Snam, through specific remuneration benchmarks created with the support of major consulting firms.

Any supplementary severance pay for the termination of employment and/or mandate is defined, consistent with the remuneration received, for executive positions characterised by the "fixed-term" nature of the employment or featuring greater risks of competitive attraction.

2018 Remuneration Policy Guidelines

The 2018 Remuneration Policy Guidelines have been defined in continuity with those established in 2017. In addition, an extension of the long-term share-based incentive plan is envisaged. This increase in the ILT plan participants will require the modification of point 1.2 of the information document, relating to the plan participants, and the related approval of the shareholders' meeting.

The 2018 Remuneration Policy guidelines have been defined in line with the aims and general principles stated and were evaluated, by the Remuneration Committee, to be consistent with the applicable market benchmarks. The remuneration instruments are summarised and explained in the following diagram:

FIGURE 2 – REWARD POLICY

Remuneration of the Chairman and non-executive Directors

The remuneration structure for the Chairman consists of a fixed remuneration consistent with the role. The remuneration of non-executive Directors is commensurate with the commitment requested in relation to participation in board Committees, with differentiation of the remuneration of the Chairman with respect to the members of each Committee, in consideration of the role attributed to this former, which involves coordinating the work and liaising with the corporate Bodies and corporate functions.

Based on the provisions of the Board of Directors at the meeting of 31 May 2016, the remuneration of the Chairman of the Board of Directors includes an annual gross fixed payment for the position of €270,000, including the annual fixed pay for Directors established by the Shareholders' Meeting, in addition to the refunding of expenses incurred in relation to the position. Given the nature of the position, there is no provision for: i) short- or long-term variable incentive components; ii) agreements concerning severance pay; iii) benefits. For the non-executive Directors, the Shareholders' Meeting of 27 April 2016 approved by way of shareholders' meeting remuneration the annual gross pay for the office of €70,000, plus the refunding of expenses incurred in relation to the position.

In coherence with of the recommendations of Article 6 C.4 of the Code of Corporate Governance, the remuneration of Non-executive directors is not linked to the financial results achieved by the company nor are they recipients of sharebased incentive plans.

There is no distinction in terms of remuneration for Independent directors.

Regarding the remuneration provided for participation in board committees, the Board of Directors in its meeting of 31 May 2016, on the basis of a proposal defined by the Remuneration Committee, with the support of a specific benchmark with companies in the FTSE MIB, proposed the following annual pay:

• for the Control and Risks Committee, with regard to the increasingly important role exercised in the oversight of company risks, €30,000 for the Chairman and €20,000 for the other members;
• for the Remuneration Committee, the Appointments Committee and the Sustainability Committee €20,000 for the Chairman and €15,000 for the other members.

Severance indemnity

Given the nature of the offices, there are no provisions for: i) components of variable short-term or long-term incentives; ii) agreements concerning severance pay; iii) benefits.

Remuneration of the CEO and the Managers with Strategic Responsibilities

The Remuneration Committee analysed the remuneration position of the CEO using specific benchmarks with peer companies comparable with Snam in terms of size and complexity. Since the position was found to be below the market median values, particularly with regard to the shortterm variable component, the Committee therefore noted and illustrated to the Board of Directors the opportunity to consider, in the future, an adjustment.

For Managers with Strategic Responsibilities, the guidelines confirm a remuneration structure adequately balanced between a fixed component consistent with the responsibilities assigned and a variable component defined within the maximum limits and designed to link remuneration to performance.

Fixed remuneration

The annual fixed remuneration of the CEO, on the basis of the evidence presented by the Remuneration Committee to the Board of Directors in its meeting of 31 may 2016, has been defined at €970,000, taking into consideration the pay established by the Shareholders' Meeting for Directors equal to €70,000, the pay approved by the Board with regard to the powers delegated, equal to €150,000; the annual gross pay for the position of General Director, equal to €750,000.

For Managers with Strategic Responsibilities, fixed remuneration is calculated based on the position and responsibilities assigned, taking into consideration the average remuneration levels on the market for positions with similar levels of responsibility and managerial complexity in large national companies and can be adjusted periodically within the framework of the annual salary review, which involves all management. Taking into consideration the reference context, current market trends and in continuity with 2017, the 2018 Guidelines include selective criteria while maintaining high levels of competitiveness and motivation. Specifically, the proposed actions involve adjustment measures directed at those in positions where the scope of responsibility has been extended or where the positioning is not higher than the market median references.

In the capacity of Snam senior managers, the CEO and the Directors with Strategic Responsibilities receive remuneration due for travel expenses, domestically and abroad, in line with the provisions of the national collective agreement and supplementary company agreements.

Variable remuneration

The variable remuneration is structured in a short-term component and a long-term share-based component with a view to achieving medium to long-term sustainability of results and value creation for shareholders. The evaluation of the performance targets assigned is carried out excluding the effects of the external variables resulting from developments in the reference scenario, with the purpose of recognizing the actual individual contribution to the achievement of the performance objectives7 assigned.

Short-term variable incentives

The annual variable component of the Annual Monetary Incentive Plan (IMA) is calculated with reference to the results of Snam in the previous year compared with the targets defined and with reference to a target incentive level (performance = 100) and a maximum level (performance = 130) respectively, equal to 50% (target) and 65% (max) of the annual fixed remuneration for the CEO and differentiated according to the position held for Managers with strategic responsibilities up to a maximum of respectively 35% (target) and 52% (max) of fixed remuneration. A threshold level is set (performance = 85) below which the short-term incentive is not paid.

⁷ The company reserves the right not to provide the annual values for these parameters, since it considers such information to be sensitive. Quantitative data regarding budget targets and their achievement will be published only at the end of the performance period. During the presentation of the strategic plan, however, the company will provide the market with guidelines for some of these parameters. Information in this respect will also be published during the year on the Company's website.

The company objectives for 2018, approved by the Board of Directors on 13 March 2018 and directly attributed to the CEO, are focused on the economic, financial and operational performance of the Company, on investments, on the development of new unregulated activities as well as on sustainability issues.

FIGURA 3 - OBIETTIVI INCENTIVAZIONE MONETARIA ANNUALE 2017 VS 2018

Free Cash Flow represents (monetary) cash flows produced by operating and non-operating activities. The objective of investments breaks down into two items: spending on investments in relation to budget (weighting of 15%) and the percentage of milestones reached for the main investment projects (weighting of 5%). The operational efficiency objective is measured in terms of the decrease in controllable fixed cost in relation to the budget. The objective relating to new activities focuses on Digital Innovation, Snam Global Solutions and LNG strategy and is measured in terms of milestones to be achieved during the year. Lastly, sustainability breaks down into two objectives: the accident frequency index for employees and contractors, measured in terms of the number of accidents that are recorded for every million hours worked during the year, and Snam's continued inclusion, at levels of excellence, in the Dow Jones Sustainability Index, FTSE4GOOD and CDP climate change sustainability indexes.

For Managers with Strategic Responsibilities, the annual variable incentive is calculated partly (25%) on the company results compared with the targets assigned to the CEO by the Board of Directors, and partly (75%) on a series of individual targets (focused on economic/financial, operating and business performance, internal efficiency

and the managerial skills model) assigned in relation to the scope of responsibility of the position held, in line with the provisions of the Company's performance Plan.

Long-term variable incentives

In 2017, in place of medium-long term monetary incentive plans, a plan based on the allocation of ordinary shares of the Company ("Performance Shares") was defined, with the aim of ensuring greater alignment of long-term variable remuneration with the primary objective of creating shareholder value. The Long-Term Incentive Plan (ILT), which was approved by the Ordinary Shareholders' Meeting of 11 April 2017, is reserved to those with managerial roles having the greatest impact on company results and provides for the annual allocation of free shares, with a maximum value of 210% for the CEO and 130% for Managers with strategic responsibilities of the fixed remuneration, after three years (vesting period) in an amount related to the results obtained. The plan is based on three indicators, measured independently: EBITDA, with a weight of 60%, measured on a linear scale with a minimum of budget -2% and a maximum equal to budget +2%; Adjusted net profit, with a weight of 30%, measured on a linear scale with a minimum equal to budget -1% and a maximum equal to budget +3%;

Sustainability, with a weight of 10%, measured on a linear scale in terms of reduction of natural gas emissions over the three-year period, compared to the results recorded at the end of 2016, with a minimum equal to a reduction of -2.5%, a target equal to a 4% reduction and a maximum equal to a reduction of -5%. The overall performance of EBITDA and adjusted net profit is calculated as the average of the annual performance of the parameters in the three-year vesting period. The achievement of the performance conditions at the maximum level, or higher, and the threshold level respectively will result in the vesting of 100% and 50% of the allocated shares. For performances below the threshold level, the percentage will always be zero.

At the end of the vesting period, an additional number of shares, defined as the "dividend equivalent", will be assigned. These will be calculated as the value of the dividends not received in relation to the actual number of vested shares. The plan also provides for a two-year lock-up period on 20% of the shares.

FIGURE 4 - CALCULATION OF THE OVERALL PERFORMANCE OF THE LONG-TERM INCENTIVE PLAN AT THE COMPLETION OF THE VESTING PERIOD

This year, the Company, pressing on with its review of the variable long-term incentive systems for the entire managerial structure, chose to promote uniformity of action by management by envisaging the possibility of extending participation in the long-term share-based plan to Company managers.

This change does not entail an increase in the number of shares already made available, nor does it modify the plan duration or any other provision already defined in the previous year.

Indemnities for termination of office or employment

For the Chief Executive Officer, in line with practices in reference markets, an indemnity is provided for the termination of his post as director and his executive position. Where both of these posts terminate concurrently, either because the term of office is not renewed upon expiry, or because it is terminated in advance, two years of fixed annual remuneration are payable upon termination of employment plus the average of the Annual Monetary Incentive paid over the last three years, subject to the application of the provisions of the national contract for executives of companies that produce goods and services. The indemnity is not payable if the posts are terminated for just cause or due to dismissal with notice on subjective grounds involving the notion of justifiability as defined by the collective agreement or in the event of a resignation. For Managers with Strategic Responsibilities, the provisions include the employment termination indemnities established by the national collective agreement. The effects of the termination of employment on the rights assigned under the scope of existing long-term incentive plans are described in the allocation regulations. The Long-Term Plan includes provisions designed to encourage the retention of personnel, including, in the case of the mutual termination of employment during the vesting period, the beneficiary keeping the right to the incentive at a reduced level, prorated based on the period elapsed between the definition of the promise and the occurrence of this event. No payment is due in cases of unilateral termination by the Company for just cause or for voluntary resignation.

Benefits

Benefits are defined in line with the practices of the reference remuneration markets and current regulations in order to complete and enhance the overall remuneration package, taking into account the assigned roles and/or responsibilities.

Therefore, in line with the provisions of national agreements and supplementary company agreements for Snam senior management, the CEO and Managers

with Strategic Responsibilities will come under the supplementary pension (FOPDIRE or PREVINDAI)⁸ , the supplementary healthcare benefits scheme (FISDE)9 and life and disability insurance cover, as well as a company car for personal and business use.

Senior Vice President of Internal Audit

For the Senior Vice President of Internal Audit, the Remuneration Committee in conjunction with the Control and Risks Committee, has drawn up: an MBO model with exclusively functional targets that can be measured, excluding economic and financial targets; the annual monetary incentive is calculated exclusively based on the results relating to this model; the assigning of minimum/ target/maximum performance levels and the evaluation of the results achieved is carried out by the Control and Risks Committee; the uniformity of the other forms of incentives and benefits paid out, compared with the entire managerial structure.

Claw-back mechanisms

A claw-back clause was introduced in 2014 for variable incentive systems, through which Snam, within the statute of limitations (ten years), can regain possession of all or part of sums paid out if it is confirmed that such amounts have been determined on the basis of targets for which the achievement of is attributable to wilful misconduct or grossly negligent conduct or, in any event, in violation of the regulations, or which have been achieved on the basis of data that is later revealed to have been manifestly incorrect. In 2015, the Remuneration Committee prepared a document that illustrates the process and the responsibilities associated with the activation of this clause. The claw back clause is activated when errors/ inaccuracies and/or the non-existence of data/actions/ facts is detected - including in relation to reports resulting from audit activities. For circumstances relating to: (i) individual performance forms, the clause will be activated by the CEO, informed by the HRO EVC, who will also inform the Remuneration Committee; (ii) the objectives of the company or medium/long-term incentive plans, the clause will be activated by the Board of Directors on the basis of the report made by the Remuneration Committee. The document illustrating the process and the responsibilities associated with the activation of this clause is delivered to all participants in incentive plans in connection with future incentive allocations or pledges.

Market benchmarks and pay mixes

The preparation of the guidelines and the evaluation of the policies implemented are carried out with the support of highly specialist independent advisors using specific remuneration benchmarks (Mercer and Willis Towers Watson).

The remuneration benchmarks used for the various types of positions are indicated in the table:

9 Fund that provides reimbursement of medical expenses to current and retired managers and their family members, www.fisde-eni.it. There is also an additional health insurance program (Generali/Previgen) supplementing FISDE.

The 2018 Remuneration Policy guidelines create a pay mix consistent with the managerial position held, with a greater weighting for the variable component for roles which have a greater impact on company results, as evidenced in the graph of the pay-mix shown below, which considers the value of the short and long-term incentives in the event of results on target, minimum level results (non-attainment of the threshold value for all the variable incentive plans, both short and longterm) and maximum level results.

Results of the Shareholders' Meeting vote

The Company, also in consideration of the result of the 2017 Shareholders' Meeting vote on the first section of the Report, carried out meetings with the stakeholders during the year on the adopted remuneration policies. These meetings provided various insights that allowed the Company to introduce some improvements, including: a graphical representation of the method for calculating the results of the targets of the ILT plan; the description of the activation procedure for claw-back clauses; the punctual information of those companies used to create the market benchmarks related to the remuneration of the CEO.

Implementation of 2017 remuneration policies

Below is a description of the remuneration measures implemented in 2017 in favour of the Chairman of the Board of Directors, the Non-executive directors, the CEO and Managers with Strategic Responsibilities. The implementation of the 2017 Remuneration Policy, as verified by the Remuneration Committee during the periodic evaluation laid down by the Code of Corporate Governance, remained in line with the general principles informing the resolutions adopted by the Board of Directors. According to the evaluation made by the Committee, the 2017 Policy was essentially in line with the market benchmarks.

Fixed pay

In 2017, Non-executive directors received, pro-rata, the fixed payments approved by the Shareholders' Meeting of 31 May 2016.

The Chairman received the remuneration approved by the Board of Directors at the meeting of 31 May 2016. The CEO received the fixed remuneration approved by the Board of Directors at the meeting of 31 May 2016 for the powers and tasks conferred, which includes the payments as a director approved by the Shareholders' Meeting. For Managers with Strategic Responsibilities, selective adjustments were made in 2017 to the fixed remuneration within the framework of the annual salary review for all Senior Management, in cases of promotion to more senior positions, or with regard to the need for adjustments of remuneration levels in relation to market benchmarks. The amounts relating to fixed pay are specified in the

respective item in Table 1 on page 27.

In the notes to this table, as far as remuneration for employees is concerned, any remuneration required by the national collective agreement and supplementary company agreements is specified.

Remuneration for participation in board committees

With regard to participation in Board Committees, in 2017 Non-executive directors received additional payments approved by the Board of Directors in the meeting of 31 May 2016. The amounts relating to these payments are specified in the respective item in Table 1 on page 27.

Variable incentives Short-term variable incentives

The incentive for the 2017 annual plan was paid out, as far as the CEO was concerned, following a company performance evaluation in relation to the achievement in 2016 of the objectives defined in line with the Strategic Plan and the annual budget in terms of:

FIGURE 8 - ACHIEVEMENT OF ANNUAL MONETARY INCENTIVE OBJECTIVES

Targets	Weight	Final summary of the 2016 targets Final result	Level of
		achieved	achievement of targets
Free Cash Flow before M&A	30%	397 mln €
Investments	30%
- Spending	20%	906 mln €
- Main project milestones	10%	4 out of 4
Operational efficiency	30%	267 mln €
Sustainability	10%
- Workplace accident frequency index	5%	0.75
- Sustainability indexes	5%	target
Below target	On target	Above target

For Managers with Strategic Responsibilities, the variable incentive paid out in 2016 was calculated as the weighted sum of 50% of Snam's performance score and 50% of the score achieved with regard to the individual objectives related to the position held, determined previously in the 2016 Snam Performance Plan.

Snam's results for 2016, evaluated on a constant basis and approved by the Board, on the recommendation of the Remuneration Committee at the meeting of 6 March 2017, led to the calculation of a performance score of 128.5 points (128 in 2015) on the measurement scale used, which includes a minimum level, target and maximum level equal, respectively, to 70, 100 and 130 points, with a threshold level of 85. For the purpose of the variable remuneration to be paid, the actual performance score resulted in:

• for the CEO, an incentive payment of €623,000 equal

to 64% of the fixed remuneration, taking into account the target incentive level (50%) and the maximum level (65%) assigned;

• for Managers with strategic responsibilities incentive payments calculated in relation to the specific performance achieved, in accordance with differentiated incentive levels depending on the position held.

The incentive payments to Managers with Strategic Responsibilities are specified in the item "Non-equity/ bonus variable payments and other incentives" in Table 1 on page 27 with details in Table 3B on page 30.

Variable long-term share-based Incentive Plan

In the meeting of 20 June 2017, the Board of Directors, following verification and recommendation by the Remuneration Committee, approved the allocation of the 2017 incentive in favour of the CEO in the maximum amount of €2,037,000, equal to 498,397 shares (based on the average share price in June 2017 of €4.0871). For Managers with Strategic Responsibilities the incentives assigned were differentiated by the level of the position up to a maximum of 100% of the fixed remuneration.

The incentives assigned to Managers with Strategic Responsibilities are specified in the item "Bonus of the year deferred" in Table 3A on page 29.

Deferred Monetary Incentive Plan

The Deferred Monetary Incentive assigned in 2014 vested in 2017. At the meeting of 6 March 2017, based on the Snam EBITDA results achieved in the threeyear period 2014-2016, the Board of Directors, on the recommendation of the Remuneration Committee, approved the multiplier to be applied to the basic incentive assigned for the purpose of calculating the amount to be paid out, at 130% on the incentive scale of 0-170% (in the three-year period 2013-2015 the multiplier was 130%).

The amounts paid out to Managers with Strategic Responsibilities are specified in the item "Bonuses for previous years – payable / paid" in Table 3B on page 30.

Long-Term Monetary Incentive Plan

In 2017, the 2014 Long-Term Monetary Incentive Plan vested. In the meeting of 25 July 2017, based on Snam's Adjusted net profit results for the three-year period 2014- 2016 measured in relation to its peer group (Enagas,

National Grid, Red Electrica, Severn Trent, Terna, United Utilities), the Board of Directors, on the recommendation of the Remuneration Committee, approved the multiplier to apply to the basic incentive assigned, at 115% on the incentive scale of 0-130% (in the three-year period 2013- 2015 the multiplier was 105%).

The amounts paid out to Managers with Strategic Responsibilities are specified in the item "Bonuses for previous years - payable /paid" in Table 3B on page 30.

FIGURE 9 - SNAM RANKING COMPARED WITH PEER GROUP - ADJUSTED NET PROFIT

Benefits

Table 1 on page 27 shows the taxable value of benefits provided in 2017 in relation to: i) annual contribution to the FOPDIRE supplementary pension scheme, ii) annual contribution to the FISDE supplementary healthcare scheme, iii) assignment of a car for personal and business use for a three-year period (value excludes the recipient's contribution).
