Comparison between Local and NYSE Practices

Among the corporate governance principles that are applicable at Pampa Energía S.A. (‘Pampa’ or the ‘Company’) are several provisions of Argentine law, including, but without limitation: (i) the Argentine Organizations Law, No. 19,550, as amended (the ‘ABOL’); (ii) the Capital Markets Act, as amended (the ‘CMA’); and (iii) the regulations of the Argentine Securities and Exchange Commission (‘CNV’) approved on 2013, as amended (the ‘Regulations’).

In addition, we follow certain corporate governance guidelines and practices that prevail in the international markets and in international regulations applicable to us (sometimes mandatory), including United States law. On August 27, 2009, we registered with the Securities and Exchange Commission (‘SEC’) as a ‘foreign private issuer’ and began to trade American Depositary Shares on the New York Stock Exchange (‘NYSE’).

Thus, we are subject to the provisions of Section 303A.11 of the NYSE’s Listed Company Manual (‘LCM’) and Item 16.G of Form 20-F of the SEC, which require foreign issuers to disclose the differences existing between their corporate governance practices and the corporate governance requirements for U.S. domestic companies under their applicable listing standards. The following table provides the comparison required under the aforementioned Section 303A.11 of the NYSE LCM and Item 16.G of the SEC’s Form 20-F:

Independent directors must constitute the majority of a listed company’s board of directors.

Under Argentine law, the board of directors of a listed company need not be composed of a majority of independent directors. Nonetheless, the CML and the CNV’s Regulations require listed companies to have a sufficient number of independent directors to form the audit committee, which must be composed of a majority of independent members.

Although not required by Argentine law, and in accordance with our audit committee’s regulations, all the members of our audit committee must qualify as independent.

This rule establishes the standards that determine whether a director qualifies as independent.

It provides that directors cannot qualify as independent unless the board of directors finds them to have no material relationship with the listed company. A number of per se exclusions from independence apply, generally triggered by having a connection, individually or through an immediate family member, to the listed company or to a company that has a material relationship with the listed company as a shareholder, employee, officer, or director of the listed company.

The CNV’s Regulations, specifically Article 11 of Section III, Chapter III, Title II I, indicate the criteria for establishing independence of a director. They provide that any director is not independent when:

(i) has been a member of the management body for the controlling entity or another company belonging to the same economic group of the issuer by a preexistent relationship to the moment of his/her election, or if said relationship had ceased to exist during the previous three years;

(ii) is associated to the issuer or any of its shareholders that have significant participation, directly or indirectly, with the issuer; or with companies with which they have significant participation, directly or indirectly; or if he/she was associated to them by an employment relationship for the past three years;

(iii) has professional relationships or is affiliated to a professional organization or entity that maintains a frequent professional relationship of such nature and of relevant volume with, or that entitles him or she to a remuneration or fees (different from those corresponding to the functions that he/she fulfills in the management body), from the issuer, the issuer’s shareholders that have directly or indirectly “significant participations” or with companies in which these too have, directly or indirectly, “significant participations. This prohibition comprises the professional relationships and affiliation during the last three years prior to the appointment as director;

(iv) holds 5% or more, directly or indirectly, of shares attached with voting rights and/or capital stock of the issuer or any company with a “significant participation” in it;

(v) directly or indirectly, sells and/or provides goods and/or services – different from those accounted for in subsection c) – frequently and in such nature and volume relevant to the issuer or its shareholders that have a “significant participation” with it, directly or indirectly, for which he or she has perceived amounts substantially superior to those perceived for his or her functions as a member of the management body. This prohibition comprises the commercial relationships that took place during the last three years prior to his/her appointment as director;

(vi) has been director, manager, administrator or principal executive of nonprofit organizations that have been benefited from funds proceeding from the company, its controlling company and any other company belonging to the same organization, by an amount superior to those described in article 12 subsection I) of the Resolution UIF No. 30/2011 and its amendments thereto;

(vii) receives any payment, including the participation in plans or stock option schemes, from the company or from another company belonging to the same economic group, other than the compensation paid as a member of the board of directors, except dividends paid as a shareholder of the company in the terms of paragraph d) and the corresponding to the consideration described in paragraph e);

(viii) has been a director for the issuer, the controlling entity or another company belonging to the same economic group of the issuer for more than ten years. If said relationship had ceased to exist during the previous three years, the independent condition will be recovered;

(ix) is spouse or a legally recognized partner, up to the third grade of consanguinity or second grade of affinity, of the members of the management body of the company that do not comply with the conditions described in the previous points;

(x) is a member of the board of directors or supervisory committee in one or more companies registered as Agente de Negociación, Agente de Liquidación y Compensación y/o Agente de Corretaje de Valores Negociables, which are members of the respective stock exchange market or depend on members of such stock exchange market; and

(xi) directly or indirectly, maintains a significant participation in one or more companies registered as Agente de Negociación, Agente de Liquidación y Compensación y/o Agente de Corretaje de Valores Negociables, which are members of the stock exchange market.

In addition, Article 4 of Section III, Chapter I, Title XII of the CNV’s Regulations provides that at each election of directors, the non-independence or independence of any candidates proposed at the shareholders’ meeting must be disclosed. Moreover, after the shareholders’ meeting in which directors are appointed, the personal data of the appointed directors and their qualification as independent or non-independent (in the latter case in the form of an affidavit executed by each director) must be disclosed to the CNV and the exchanges where the company has its securities listed.

The audit committee must have at least three members, all of whom must satisfy the requirements for independence set out in Section 303.A.02, in the absence of an applicable exemption, Rule 10A-3(b)(1).

In addition, the audit committee must have written regulations establishing: (i) the purpose of the committee; (ii) the annual assessment of the committee’s performance; and (iii) the committee’s duties and responsibilities.

Finally, the rule establishes that listed companies must have internal audit functions within their organization in order to assist both the audit committee and the company’s management in matters related to risk and internal control processes.

Article 109 of the CML and Article 16, Section 5, Chapter III, Title II of the CNV Regulations provide that the audit committee must have at least three board members, the majority of whom must qualify as independent. All the members of our audit committee qualify as independent.

Argentine law requires the audit committee to issue its own regulations. The scope of the committee’s powers and obligations is detailed in Article 110 of the CML and Article 17 and following sections of Section 5, Chapter III, Title II, of the CNV’s Regulations. Such obligations and responsibilities are similar to those attributed to this body under the U.S. law.

Our audit committee has approved its own written regulations.

Argentine law does not require the audit committee to conduct an annual self-assessment. However, the CNV’s Regulations recommend that all directors (i.e., not only the independent directors who are members of the audit committee) complete a self-assessment.

We have adopted this recommendation and have developed a self-assessment form to be completed by all our directors at the close of each fiscal year.

Argentine laws contain no rules regarding internal audit functions. However, Pampa has an internal audit department that is supervised by, and reports to, Pampa’s Audit Committee. Additionally, Pampa’s audit committee regularly reviews, during its meetings, the internal audit reports submitted to it.
