13.1 The Company shall be managed by a Board of Directors numbering no fewer than five and no more than nine members, with their number and term of office being established by the Shareholders' Meeting at the time of appointment.
13.2 The Directors may be appointed for a period not exceeding three fiscal years, their term in office shall expire on the date of the Shareholders' Meeting convened to approve the financial statements relating to the last fiscal year in which the Directors hold office, and may be re-elected.
13.3 The Board of Directors shall be appointed by the Shareholders' Meeting in compliance with the provisions of these Bylaws and with the aim of ensuring gender balance in the composition of the Board itself.

The Board of Directors shall be appointed on the basis of slates submitted by the shareholders, on which candidates must be listed by means of a progressive number.

The slates shall be deposited at the Company's registered offices no later than the twenty-fifth day preceding the date in which the Shareholders' Meeting shall convene to discuss the appointment of the members of the Board of Directors, and shall be made available to the public at least twenty-one days prior to the Shareholders' Meeting, in accordance with the terms and conditions provided for in the law and Consob's own regulations.

Each shareholder may submit or participate in the submission of and vote a single slate in accordance with the terms set forth in the aforementioned legislative and regulatory provisions.

Each candidate must only appear on one slate, under penalty of ineligibility.

Slates may only be presented by Shareholders who, alone or together with other Shareholders, represent at least 2% or are together the owners of such other stake in the capital as Consob may set in its regulations. The ownership of the minimum percentage shareholding necessary for the submission of slates is determined in consideration of the number of shares registered in the shareholder's favour on the date on which the slates are filed with the Company.

In order to prove ownership of the number of shares necessary to submit slates, shareholders must produce the relevant certification issued in accordance with the law by qualified intermediaries within the deadline set for the publication of slates by the Company.

At least one director, if the Board is made up of no more than seven members, or at least three directors, if the Board is made up of more than seven members, must meet the requirements of independence laid down for statutory auditors of listed companies.

The slates shall expressly bear the names of candidates who meet the aforementioned requirement of independence. At least two fifths of the members of the Board of Directors, or any different proportion – if higher – as envisaged by provisions in force pro tempore on the matter, must belong to the less represented gender, with mandatory rounding up, in the event of a decimal figure, to the next whole number, if there are five or more members.

Pursuant to the Decree of the President of the Council of Ministers of 25 May, 2012, containing the "Criteria, conditions and terms for the adoption of the model for the demerger of Snam S.p.A., in accordance with Article 15, of Law no. 27 of 24 March, 2012", the directors may not be appointed to offices in administrative or control bodies or in managerial positions at ENI S.p.A. and its subsidiaries, nor may they entertain any direct or indirect, professional or financial relationship with the aforementioned companies.

Furthermore, all candidates must meet the requirements of integrity laid down in current legislation. In the slates that present three or more candidates, at least two fifths of the candidates, or any different proportion – if higher – as envisaged by provisions in force pro tempore on the matter, must belong to the less represented gender, with mandatory rounding up, in the event of a decimal figure, to the next whole number, if there are five or more candidates, and as better specified in the call notice for the Shareholders' Meeting.

At the time of deposit, each slate, under penalty of its inadmissibility, must be accompanied by the professional CV of each candidate, along with the declarations by which candidates accept their candidacy and, under their own responsibility, declare the non-existence of reasons for ineligibility and incompatibility, in addition to their ownership of the aforementioned requirements of integrity and independence.

The appointed directors must notify to the Company of their loss of the aforementioned requirements of independence and integrity, as well as the occurrence of causes for ineligibility and incompatibility, if any.

13.4 The Board of Directors shall periodically evaluate the independence and integrity of directors, and verify the non-existence of reasons for ineligibility and incompatibility. In the event that a director does not own or loses the declared and legally prescribed requirements of independence or integrity, or if reasons for ineligibility and incompatibility have materialized, the Board of Directors shall remove the director from office and replace him/her, or invite him/her to remedy the causes of incompatibility within a specified deadline, under penalty of removal from office.

13.5 The directors shall be elected as follows:

a) seven tenths of the directors to be elected shall be selected from the slate that obtains the majority of votes expressed by the shareholders (the "Majority Slate"), in the order in which they are listed on the slate, rounding down in the case of decimal number;
b) the remaining directors will be selected from the other slates (the "Minority Slates") that are in no way – directly or indirectly – connected to shareholders who have submitted or voted for the slate that received the majority of votes; to this end, votes obtained by the slates will be subsequently divided by one or two or three, depending on the progressive number of directors to be elected. The quotients thus obtained shall be assigned progressively to candidates from each of these slates, according to the order shown in them. The quotients thus assigned to candidates from the different slates shall be arranged in a single decreasing ranking. Those obtaining the highest quotients shall be elected. If several candidates obtain the same quotient, the candidate from the list which has not yet elected any director or that has elected the smallest number of directors shall be elected. If none of these lists has yet elected a director or if all have elected the same number of directors, the candidate

from the list obtaining the greatest number of votes shall be elected. If the voting on slates is tied and the quotient is also tied, a new vote by the entire Shareholders' Meeting shall be held, and the candidate winning a simple majority of votes shall be elected;

b-bis) in the event that the Majority Slate does not contain a sufficient number of candidates to reach the number of directors to be elected pursuant to letter a) above, all candidates listed in said slate shall be appointed, based on their progressive order in said slate; in turn, after appointing the other directors from the Minority Slates, pursuant to letter b) above, for the number of positions established for these minority slates, which is three tenths of the total, the remaining directors shall be appointed, for the positions not covered by the Majority Slate, from the minority list that obtains the greatest number of votes among the Minority Slates (the "First Minority Slate") in relation to the capacity of said slate. In the event of insufficient capacity of said slate, the remaining directors shall be appointed, with the same procedures, from the following slate ("Second Minority Slate") or any subsequent slates, based on the number of votes and capacity of the slates themselves. Lastly, if the total number of candidates on the slates presented – in both the Majority Slate and Minority Slates – is lower than the number of the directors to be elected, the remaining directors shall be elected by the shareholders' meeting with the resolution approved in accordance with letter d) below;

c) if, following the application of the procedure described above, it is not possible to appoint the minimum number of independent directors required by the Bylaws, then the quotient of the votes to attribute to each candidate on the slates is calculated by dividing the number of votes obtained by each slate by the number of the order of each one of the aforementioned candidates; candidates who do not meet the requirements of independence and have the lowest quotients among candidates from all slates are replaced, starting with the last candidate, by independent candidates listed on the same slate of the replaced candidate (following the order in which they are listed), or, alternatively by individuals meeting the requirements of independence, who have been appointed in accordance with the procedure described under letter d). If candidates taken from different lists have obtained the same quotient, the candidate from the list from which the highest number of directors has been taken shall be replaced, or, if these numbers of directors are the same, the candidate taken from the list with the fewest votes shall be replaced, or, if the number of votes is the same, the candidate who receives the fewest votes in a dedicated resolution by the Shareholders' Meeting shall be replaced;
c-bis) if the application of the procedure described under letters a), b) and b)-bis does not permit compliance with the Bylaws regulations on gender balance, the quotient of votes to be attributed to each candidate from the slates is calculated by dividing the number of votes obtained by each slate by the number of the order of each candidate; the candidate of the most represented gender who has the lowest quotient among the candidates from all the slates is replaced, without prejudice to the minimum number of independent directors, by the candidate representing the less represented gender (with the subsequent higher number of order) on the same slate as the replaced candidates, or, alternatively, by the individual appointed in accordance with the procedure described under letter d). In cases in which candidates from different slates have obtained the same minimum quotient, the candidate to be replaced shall be the candidate of the slate from which the greatest number of directors is selected, or, subordinately, the candidate from the slate that has received the least number of votes, or, in case of equal number of votes, the candidate that has obtained less votes by the Shareholders' Meeting in a specific voting round;
d) for the appointment of directors, who, for any reason, are not appointed in accordance with the procedures described above, the Shareholders' Meeting shall resolve by legal majority, in order to ensure that the composition of the Board of Directors is compliant with the law and the Bylaws. Current peremptory legislative and regulatory provisions shall constitute, in any case, an exception
13.6 The slate voting procedure shall be applied only in case of renewal of the entire Board of Directors.

to these policies.

13.7 The Shareholders' Meeting may change the number of Directors, including during its term, within the limitations laid down in subsection 1 of this Article, and shall make the respective appointments according to the procedures set out in Article 13.5 (d) above. The term of office of

Directors appointed in this way shall expire with the term of those currently in office.

13.8 If in the course of the financial year one or more vacancies occur on the Board, the procedure specified in Art. 2386 of the Italian Civil Code shall be followed.

In any case, respect for the minimum number of independent directors and the presence of least two fifths, or any different proportion - if higher - as envisaged by provisions in force pro tempore on the matter of the directors belonging to the less represented gender must be ensured, with mandatory rounding up, in the event of a decimal figure, to the next whole number, if there are 5 or more members.

If there is no longer a majority of directors, the entire Board of Directors shall resign, and a Shareholders' Meeting shall be convened in a timely manner by the Board of Directors for the reconstitution of the latter.

The Shareholders' Meeting shall appoint the statutory auditors and determine their compensation. Statutory Auditors shall be chosen from those in possession of the requisites of integrity and professionalism laid down by applicable legislation, in particular by Decree no. 162 of 30 March 2000 of the Ministry of Justice.

For the purposes of the aforementioned decree, topics strictly under the purview of the Company shall be: commercial law, business administration and corporate finance.

For the same purpose, the engineering and geological sectors are under the direct purview of the Company.

20.2 The statutory auditors may be appointed to administrative and control bodies of other companies within the parameters set by Consob through its own regulations, with the exclusion of the offices indicated in Article 13.3 of these Bylaws.
20.3 The Board of Statutory Auditors shall be appointed by the Shareholders' Meeting, on the basis of slates submitted by the shareholders, on which candidates shall be listed by means of a progressive number and in a number that shall not exceed the number of members of the body to be elected. One standing auditor and one alternate auditor must belong to the less represented gender.

For the deposit, submission and publication of slates, the procedures governed by the provisions of Article 13.3 of these Bylaws shall be applied.

Each shareholder may submit or participate in the submission of and vote a single slate in accordance with the terms set forth in the aforementioned legislative and regulatory provisions.

Each candidate must only appear on one slate, under penalty of ineligibility.

The slates are broken into two sections: the first for candidates to the office of standing auditor, the second for candidates to the office of alternate auditor. At least the first candidate in each section must be enrolled in the register of external auditors and have worked on legal audits for a period of

not less than three years.

The slates that, considering both sections, contain a number of candidates equal to or greater than three and compete for appointment to the majority of the members of the Board of Statutory Auditors, must include, as also specified in the call notice for the Shareholders' Meeting, members of the less represented gender in the number stated in the first paragraph of this art. 20.3.

Two standing auditors and two alternate auditors are taken from the slate that wins the majority of the votes. The other standing auditor and the other alternate auditor shall be appointed in accordance with provisions set forth in Article 13.5, letter b), to apply distinctly to each of the sections in which the other slates are articulated.

In the event that, mutatis mutandis, a similar situation should occur to that laid down in Article 13.5 b-bis) above, the procedures pursuant to the same letter b-bis) shall apply both for the standing auditors and alternate auditors, insofar as compatible with current regulations and with this Article.

The Shareholders' Meeting shall appoint as Chairman of the Board of Statutory Auditors the standing auditor elected in accordance with the provisions set forth in Article 13.5 letter b).

If the application of the procedure described above does not allow, as regards standing auditors, compliance with the gender division criterion set out in the first subsection of this art. 20.3, the quotient of votes to be attributed to each candidate from the standing auditor sections of the different slates, shall be calculated by dividing the number of votes obtained in each slate by the number of the order of each of the aforementioned candidates; the candidate of the most represented gender who has the lowest quotient among candidates from all slates, shall be replaced by the candidate belonging to the least represented gender listed, with the subsequent highest order number, in the same standing auditor section of the slate of the replaced candidate, or, subordinately, in the alternate auditor section of the same slate of the replaced candidate (who, in this case, shall take over the position of the alternate candidate he/she replaces); otherwise, if this operation does not allow compliance with the gender division criterion set out in the first subsection of this art. 20.3, the candidate shall be replaced by the individual appointed by the Shareholders' Meeting with a legal majority, so that a Board of Statutory Auditors compliant with the law and the Bylaws can be constituted.

In cases in which candidates from different slates have obtained the same quotient, the candidate to be replaced shall be the candidate of the slate from which the greatest number of auditors is selected, or, subordinately, the candidate from the slate that has received the least number of votes, or, in case of equal number of votes, the candidate that has obtained less votes by the Shareholders' Meeting in a specific voting round.

For the appointment of standing auditors, who, for any reason, are not appointed in accordance with the procedures described above, the Shareholders' Meeting resolves by legal majority, in order to ensure that the composition of the Board of Statutory Auditors is compliant with the law and the Bylaws.

In the case of replacement of the statutory auditor selected from the minority slates, the office shall be held by the alternate auditor selected from such slates.

In the case of replacement of a statutory auditor selected from the slate that obtained the majority of votes, the office shall be held by the first alternate auditor from the same slate; if the replacement does not allow compliance with the gender division criterion set out in the first subsection of this art. 20.3, the office shall be held by the second alternate auditor selected from such slate.

The slate voting procedure shall be applied only in case of renewal of the entire Board of Statutory Auditors. Current peremptory legislative and regulatory provisions shall constitute, in any case, an exception to these policies.

20.4 Outgoing statutory auditors can be re-elected.

20.5 With prior notification to the Chairman of the Board of Directors, the Board of Statutory Auditors may convene a Shareholders' Meeting and meetings of the Board of Directors. The authority to convene meetings of the Board of Directors may be exercised individually by each member of the Board of Statutory Auditors; the authority to convene a Shareholders' Meeting must be exercised by at least two members of the Board of Statutory Auditors.
