PRINCIPLES OF CORPORATE GOVERNANCEThe principles that guide the governance of the Company are established in:The Corporate Bylaws, the latest amendment to which was approved by a resolution of the Shareholders’ Meeting held on 2 April 2004.The Shareholders’ Meeting Regulations, approved at the Shareholders’ Meeting of 19 June 2003 and amended at the Meeting of 2 April 2004.The Board Regulations approved on 28 October 2003.The Internal Regulations on Conduct in Stock Markets, approved by the Board of Directors on 27 May 2003.The Corporate Integrity Rules, approved by the Board of Directors on 25 March 2003. The Company’s Corporate Bylaws contain, together with the mandatory legal provisions, the criteria that guide the governance of the Company and the bodies composing it — namely, the General Shareholders’ Meeting, the Board of Directors and the Executive Committee. Noteworthy among these principles are transparency, respect for shareholders’ rights, the duty of diligence and loyalty incumbent upon Directors, and the establishment of a set of rules governing the functioning of the corporate bodies that, subject to legal requirements, encourages shareholder participation in decision-making processes. The Shareholders’ Meeting Regulations, the purpose of which is to regulate its functioning and promote shareholder participation in the General Meeting by establishing mechanisms that facilitate the provision of information and encourage share-holders to contribute to corporate decision-making by exercising their voting rights and their rights to participate in debates. The Board of Directors Regulations regulate the organisation and functioning of the Board of Directors in accordance with Article 36 of the Corporate Bylaws. They are based on three concepts: promoting transparency in the conduct of the governing bodies of the Company and in all its dealings, fostering effective business management, and the assuming of responsibilities by Senior Management and the Board of Directors to the Shareholders of the Company. The Internal Regulations on Conduct in Stock Markets, which determine the rules of conduct for securities market transactions, with a view to contributing to their transparency and to investor protection. These regulations are based on the principles of impartiality, good faith, placing common interests before individual interests, and care and diligence in information usage and market operations. The Corporate Integrity Rules consist of the Charter Governing Senior Management, the Charter Governing Executives and the Employees’ Code of Conduct. They develop the principles and values of the Company, lay down the rules governing dealings with customers and suppliers, and establish the principles that should be followed by employees in their work: ethical conduct, professionalism and confidentiality. They also establish the limitations and define the incompatibilities arising from their status as executives and senior executives. All these documents are available on the Company website at www.endesa.es.

CORPORATE GOVERNANCE RESOLUTIONS In 2006, the corporate bodies of ENDESA, S.A. adopted the following resolutions on corporate governance: On 10 January 2006, the Board of Directors voted unanimously in favour of the following resolution adopted by the Executive Committee of the Board of Directors on 26 December 2005: “To empower the Chief Executive Officer so that he may provide Gas Natural or any third party with access to information that could facilitate the progress of its bid in course or the formulation of any rival bid, all this in the interest of ENDESA shareholders and subject to the most stringent confidentiality standards and prevailing legislation”. On 16 January 2006, the Board of Directors voted unanimously in favour of the following items: The Audit and Compliance Committee Report, the Appointments and Compensation Committee’s Annual Report on Directors’ Compensation and the Annual Corporate Governance Report. To prepare the annual financial statements for 2005, both for the Company and the Consolidated Group and, in consideration of the results obtained, submit to the General Shareholders’ meeting a proposal for a dividend of Euro 2.4 per share payable against 2005 earnings. To call a General Shareholders’ Meeting for 24 February 2006, at first call, or 25 February 2006, at second call. To draw up the proposed resolutions to be submitted at the General Shareholders’ Meeting. To decide on the regulations governing voting rights and proxy voting to be applied at the General Shareholders’ Meeting from moment the meeting call is announced. To request the presence of a notary from the Madrid Bar Association to take minutes of the meeting. At its meeting of 24 January 2006, the Board of Directors examined the authorisation process for the takeover bid for ENDESA presented by Gas Natural and resolved to empower the Executive Committee and the CEO with the necessary authority to file an appeal against this operation with the Spanish Council of Ministers should it be considered in breach of the law, always acting in the defence of ENDESA shareholders. Lastly, the Board of Directors examined and approved the ENDESA Group’s annual budget for 2006 in the terms presented. On 21 February 2006, the Board of Directors studied the rival bid for the takeover offer launched by Gas Natural for ENDESA, presented that morning by E.ON, and voted unanimously to release the following statement: “With regard to the takeover bid for ENDESA presented today by E.ON and in view of the conditions offered, the Board of Directors has, in the interest of the company and its shareholders, unanimously drawn up the following considerations and preliminary valuation: 1. Pursuant to current legislation, ENDESA has held talks with companies interested in the takeover process initiated by Gas Natural on 5 September 2005. E.ON was one of these companies. These talks have resulted in no firm commitment from any of the parties involved. 2. The offer made by E.ON, a rival to the bid presented by Gas Natural, is a cash offer which will allow shareholders to clearly assess the price offered and thereby facilitate their decision. 3. The price offered by E.ON is clearly better than the price offered by Gas Natural, although the Board of Directors believes it still does not adequately reflect ENDESA’s real value. 4. The Board of Directors values positively the fact that the operation proposed by E.ON will maintain ENDESA’s industrial project intact, envisaging no asset sales. This preliminary valuation should be read without prejudice to the report ENDESA’s Board of Directors is required to issue under article 20.3 of Royal Decree 1197/1991 of 26 July, governing takeover offers, once the CNMV has approved the prospectus presented by E.ON. The Board of Directors reiterates its commitment to the Company’s business project, which includes a strategic plan that ratifies and confirms its growth and earnings expectations.” The Shareholders’ Meeting held on 25 February 2006, adopted the following resolutions at the proposal of the Board of Directors: To approve the financial statements (balance sheet, statement of income and notes to financial statements) of the Company and its Consolidated Group for the year ended 31 December 2005, as well as the conduct of the Company’s business in that fiscal year. Appropriation of income and distribution of dividends. To appoint the current external auditors, Deloitte, S.L., as the auditors of ENDESA, S.A. and of its Consolidated Group for 2006. To engage said audit firm for the external audit of the financial statements of ENDESA, S.A. and of its Consolidated Group for 2006, delegating authority to the Board

of Directors, in the broadest terms, to determine the other terms and conditions of its engagement. To revoke and render void the authority for the derivative acquisition of shares of the Company granted by the Annual Shareholders’ Meeting held on 27 May 2005. To grant new authority for the derivative acquisition of treasury stock, as well as pre-emptive rights of subscription of treasury stock, in accordance with Article 75 of the Corporations Law, on the following conditions: a) Acquisitions may be made by any legally permitted means, directly by ENDESA, S.A. itself, by companies of its Group, or by an interposed person, up to the maximum figure permitted by the Law. b) Acquisitions shall be made at a minimum price per share of its par value and a maximum price equal to its market price plus an additional 5 percent. c) The term of this authority shall be 18 months. Acquisitions may only be made following the publication of the outcome of the takeover bid made by Gas Natural SDG S.A. for ENDESA S.A.’s shares, or, if appropriate, from the moment in which the takeover bid is deemed to be invalid for any reason (or if a rival bid is launched), in accordance with applicable securities market legislation. To delegate to the Board of Directors of the Company the broadest powers to adopt as many resolutions as may be necessary or appropriate for the performance, implementation, effectiveness and success of the resolutions made at the Shareholders’ Meeting. To empower the Chairman of the Board, Manuel Pizarro Moreno, the Managing Director, Rafael Miranda Robredo, and the General Secretary and Secretary of the Board, Salvador Montejo Velilla, so that each and any one of them individually may: (i) carry out such acts, legal businesses, contracts and transactions as may be appropriate in order to register the preceding resolutions with the Mercantile Registry, including, in particular and inter alia, the power to appear before a Notary Public in order to execute the public deeds or notary records which are necessary or appropriate for such a purpose, to publish the pertinent legal notices and formalise any other public or private documents which may be necessary or appropriate for the registration of such resolutions, with the express power to remedy them, without altering their nature, scope or meaning; and (ii) appear before the competent administrative authorities, in particular, the Ministries of Economy and Finance and Industry, Tourism and Commerce, as well as before other authorities, administrations and institutions, especially the Spanish National Securities Market Commission, the Securities Exchange Governing Companies and any other which may be competent in relation to any of the resolutions adopted, in order to carry out the necessary formalities and actions for the most complete implementation and effectiveness thereof. On 7 March 2006, the Board of Directors agreed unanimously to adopt the following resolutions: To appoint José María Fernández Cuevas as a member of the Audit and Compliance Committee. He will also remain a member of the Board of Directors’ Executive Committee. To approve, in accordance with Article 20 of Royal Decree 1197/1991 of 26 July, governing takeover offers, the report prepared by ENDESA’s Board of Directors on the takeover bid submitted by Gas Natural SGG, S.A., which reads as follows: REPORT ISSUED BY ENDESA, S.A’S BOARD OF DIRECTORS REGARDING THE TENDER OFFER BY GAS NATURAL SDG, S.A. The members of the Board of Directors of ENDESA, S.A. (hereinafter “ENDESA” or the “Company”) present or represented at the meeting held on 7 March 2006, approved by unanimous decision, under Article 20 of Royal Decree 1197/1991 of 26 July regarding tender offer practices, the following report regarding the Tender Offer (hereinafter the “Tender Offer” or “Offer”) by Gas Natural SDG, S.A. (hereinafter “Gas Natural” or the “Offeror”). Items 1 and 2 describe the Board’s position, and the rest, in accordance with the above referenced decree, provide detailed information and opinions affecting each member individually. Opinion of the Board of Directors on the Tender Offer made by Gas Natural The Board of Directors strongly recommends that ENDESA, S.A.’s shareholders reject Gas Natural’s Offer for the following reasons: A. The Offer Price is substantially lower than ENDESA’s value under customary valuation criteria and lower still than ENDESA’s value in a change-of-control transaction such as the Gas Natural Offer, in which a control premium is normally paid. B. ENDESA on a standalone basis is likely to generate greater value for its shareholders in the short and long term than Gas Natural’s offer. C. Most of the consideration (65.54%) offered by Gas Natural consists of its ordinary shares, whose current trading price overstates the weak prospects of Gas Natural’s business in the medium and long term. D. The proposed combined group’s performance is likely to reflect substantially lower synergies, and substantially

higher negative synergies and integration costs, than are currently estimated by Gas Natural. E. The asset divestments resulting from Gas Natural’s agreement with Iberdrola and the conditions imposed on the transaction by the Spanish Council of Ministers would significantly weaken ENDESA’s and Gas Natural’s existing business while strengthening the proposed combined group’s main competitor, Iberdrola, and creating substantial regulatory risk. F. Gas Natural’s agreement with Iberdrola does not maximise the value of the assets being sold as it precludes a competitive auction process. G. The control exercised over Gas Natural by its principal shareholders creates a risk of conduct that may run counter to the interests of ENDESA’s shareholders. H. The Offer Price is substantially lower than a competing all-cash offer announced by E.ON Zwölfte Verwaltungs GmbH (“E.ON”). Reasons The principal reasons for the conclusions and recommendation of the Board of Directors set forth above are as follows: A. The Offer Price is substantially lower than ENDESA’s value under customary valuation criteria and lower still than ENDESA’s value in a change-of-control transaction such as the Gas Natural Offer, in which a control premium is normally paid. ENDESA’s closing price was Euro 27.45 on 6 March 2006, the day prior to the issue of this report, reflecting the market’s perception of ENDESA’s strong fundamentals as well as market trends in the electricity sector. The closing price of ENDESA’s ordinary shares on 6 March 2006 was 27% higher than the Offer Price. The implied value of ENDESA’s ordinary shares on 6 March 2006 based on the average of the current trading multiples of other Iberian utility companies is 52% higher than the Offer Price. The Offer Price reflects an EV/EBITDAmultiple of 8.5 x in 2005, clearly lower than the average multiple of 10.5 x for Unión Fenosa, Iberdrola and EDP. ENDESA’s shareholders are entitled to receive a premium for their shares in a change-of-control transaction (“control premium”) such as the Gas Natural Offer in accordance with market practice. However, the Offer Price does not include any control premium. B. ENDESA on a standalone basis is likely to generate greater value for its shareholders in the short and long term than Gas Natural’s offer. ENDESA’s strategic plan sets forth clear, attainable objectives through to 2009 based on the company’s strong economic and financial fundamentals, with a focus on returning cash to shareholders, achieving strong organic growth, implementing an efficiency plan and divesting non-core assets, which together provide a platform for long-term value creation for shareholders. The Company’s key financial targets to 2009 include: Annual average EBITDA growth of 10-11% and annual net income growth of above 12%. An efficiency plan envisaging EBITDA savings of of Euro 225 million by 2009. The disposal of non-core assets in excess of Euro 4 billion. Annual dividend growth from ordinary activities of at least 12%, and 100% payout of net capital gains on disposals of non-core assets, with a commitment to return to shareholders more than Euro 7 billion in dividends from 2005 to 2009. The implementation of a Euro 14.6 billion investment plan during the same period based on organic growth while maintaining a leverage ratio below 1.4 (calculated by dividing total net debt by total equity, including minority interests). ENDESA’s performance in 2005 demonstrates the feasibility of the 2009 targets presented in the Company’s Strategic Plan for 2005 to 2009. 33% growth in EBITDA in 2005 and 154% in net income. 34% (Euro 181 million) of efficiency plan targets for 2009 met in 2005. Non-core asset disposals in excess of Euro 3 billion in 2005, of which over Euro 2.6 billion resulted from the sale of Auna, delivering 75% of the Company’s committed disposals. Dividend of over Euro 2.5 billion already approved by shareholders against 2005 earnings, delivering 35% of the Company’s commitment on dividends. A sound financial position, evidenced by a leverage ratio of 1.1 at 31 December 2005. C. Most of the consideration (65.54%) offered by Gas Natural consists of ordinary shares, whose current trading price overstates the weak prospects of Gas Natural’s business in the medium and long term. According to the figures furnished by Gas Natural, its share of the liberalised gas supply market has declined

from 80% to 48% in just four years. This decline in market share is expected to continue in view of trends seen in other liberalised markets. Gas Natural’s gas distribution business in Spain has generated unsustainable returns as compared with those of its peer companies in other European countries. As a result, Gas Natural’s returns for this business may face significant regulatory risk in the future. Gas Natural has no gas production of its own, and its joint venture with Repsol has been weakened by Repsol’s recent write-down of reserves. Gas Natural’s earnings growth has historically depended on income consolidation and capital gains from its investment in Enagas, which Gas Natural would be required to reduce as a result of this Transaction from 9.9% to one percent. Excluding the impact of Enagas, it is estimated that Gas Natural’s net income would have totaled approximately Euro 471 million in 2005 compared to Euro 442 million in 2004, demonstrating annual growth of 6.5% compared to Gas Natural’s reported annual growth rate of 16.7% and its average target annual growth rate of 10%. Gas Natural’s shares are substantially less liquid than ENDESA’s, with an average daily trading volume of Euro 22 million in 2005 prior to the announcement of the Gas Natural Offer, compared to Euro 193 million for ENDESA. As a result of this illiquidity, Gas Natural’s share price may not reflect the market’s views about the company’s performance as accurately as would be the case with a more liquid stock. This concern is underscored by the fact that, as of the trading day prior to the announcement of the Gas Natural Offer, Gas Natural’s share price was overvalued by more than 10% relative to the average target price estimated for Gas Natural by research analysts. Gas Natural is proposing to issue up to 602,429,955 new ordinary shares to ENDESA shareholders, which is 4.8x Gas Natural’s current free float. As a result of this capital increase, the price of Gas Natural share price could vary substantially, affecting the value of the consideration, as Gas Natural itself has disclosed its prospectus: “The market value of Gas Natural shares offered as consideration in the Offer may decrease as a result of their stock market performance.” In the event Repsol sells its 30.8% stake in Gas Natural, Gas Natural’s share price is likely to be adversely affected by the large number of shares made available for sale in the market. D. The combined group’s performance is likely to reflect substantially lower synergies –and substantially higher negative synergies and integration costs –than are currently estimated by Gas Natural. Gas Natural’s forecast pre-tax synergies of Euro 350 million per year by 2008 are overstated. ENDESA estimates that, prior to the divestments that are required by the Spanish Council of Ministers or planned by Gas Natural, the maximum amount of synergies achievable would be in the range of Euro 80 million to Euro 140 million, and that, after the required divestments, any potential synergies would be even lower. ENDESA estimates that the combined Group’s cost structure will increase by more than Euro 200 million per year as a result of negative integration synergies that Gas Natural has ignored, including the adoption of a territorial corporate structure that has proved ineffective in the past. This figure does not include additional negative synergies from asset disposals and non quantified regulatory risk. In addition, ENDESA estimates that integration costs from the transaction would amount to more than Euro 600 million as compared to Gas Natural’s estimate of Euro 243 million. ENDESA’s concerns about the combined Group’s profitability are heightened by the absence of any adequately supported financial targets or forecasts for the proposed new company, as is evident from the Gas Natural Prospectus. As a result, neither ENDESA nor its shareholders have the necessary information with which to assess the combined Group’s ability to create value for shareholders in the future. ENDESA is concerned that Gas Natural’s management does not have the experience needed to integrate or manage a company of the new Group’s scale and complexity. The largest company acquired by Gas Natural in the past five years had an enterprise value of Euro 272 million, which is 207 times smaller than ENDESA’s enterprise value of Euro 56.353 billion as of the date prior to the issue of this report. ENDESA believes that the challenges for Gas Natural’s management of running the proposed combined Group and executing the integration and divestments required create a very substantial risk of value destruction for shareholders. E. The asset divestments resulting from Gas Natural’s agreement with Iberdrola and the conditions imposed on the transaction by the Spanish Council of Ministers would significantly weaken ENDESA’s and Gas Natural’s joint business while strengthening that of its main competitor, Iberdrola, and creating substantial regulatory risk. The asset portfolio of the combined Group after the required divestments would be less attractive than ENDESA’s current portfolio and offer fewer opportunities to create sustainable value for shareholders, due to the following reasons (among others): The new combined Group would be forced to sell more than Euro 10 billion of assets in key markets such as Spain, Italy, France and Poland, including the

sale of 11,632 MW of assets in operation and 1,200 MW in the pipeline. The new combined Group’s estimated share of the electricity generation market in Spain would fall to 30% compared to ENDESA’s current share of 39%, while Iberdrola’s estimated share of the electricity generation market would rise to 36% from 27%, handing ENDESA’s market leadership to the new Group’s main competitor as recognised by Gas Natural. Moreover, the new Group’s production would cover a much smaller portion of the company’s supply business, requiring it to purchase as much as 37% of its supply requirements in the spot market, compared to 9% for ENDESA today. This added exposure to price fluctuations in the wholesale market would make the combined Group’s results more volatile. Meanwhile, Iberdrola’s estimated generationsales balance would be significantly improved, reducing the supply that it would have to purchase on the spot market from 31% to 12%. The new combined Group would be required to divest approximately 5,400 MW of its generation capacity in Italy, France and Poland, which represents 58% of ENDESA’s current generation capacity in these countries. These divestments imply the total loss of ENDESA’s business in France and a reduction of nearly half of ENDESA’s business in the Italian generation market. Consequently, the transaction would result in a substantial setback to ENDESA’s European growth project, which has been an increasingly significant contributor to Group results in recent years. Gas Natural’s failure to provide any information regarding its planned divestments makes it more difficult to assess their impact on the proposed combined group. The new combined Group’s geographic profile would be less balanced and exposed to greater risk due to its increased dependence on Latin America. As a result of these divestments, the proposed combined group would be only 10% larger in terms of enterprise value and just 2% in terms of EBITDA than ENDESA is today, with a smaller electricity business than ENDESA’s, a smaller presence in Europe, reduced geographic diversification in its business and less balance between generation and sales. ENDESA believes that the proposed combined group would aggravate the structural problems currently faced by the electricity sector. The transaction would reduce the transparency and credibility of the wholesale market for electricity. The transaction would impede progress toward an additive tariff that reflects the real costs of the sector, an issue on which Gas Natural has taken contradictory positions. The transaction would create substantial overlap in gas and electricity distribution networks in many areas of Spain. As a result of the foregoing, the proposed combined group would face a high level of regulatory risk. F. Gas Natural’s agreement with Iberdrola does not maximise the value of the assets being sold because it precludes a competitive auction process. ENDESA shareholders are highly unlikely to receive the full value of the assets that would have to be sold due to the terms of Gas Natural’s agreement with Iberdrola and the forced nature of the sale. Recent transactions in Spain indicate that competitive auction processes generate proceeds of as much as 40% above the market consensus on “fair value”. However, the price mechanism established in Gas Natural’s agreement with Iberdrola would not generate prices at levels similar to a competitive auction process. G. The control exercised over Gas Natural by its principal shareholders creates a risk of conduct that may run counter to the interests of ENDESA’s shareholders. As stated in Gas Natural’s U.S. Prospectus, the interests of Gas Natural’s principal shareholders may differ from those of Gas Natural and its minority shareholders, which could create conflicts of interest affecting the conduct of Gas Natural’s business or potential changeof- control scenarios. H. The Offer Price is substantially lower than a competing all-cash offer announced by E.ON Zwölfte Verwaltungs GmbH (“E.ON”). On 21 February 2006, E.ON, a private European energy company, announced that it intended to make an offer for all ENDESA ordinary shares and ENDESA ADSs at a price of Euro 27.50 per share in cash. E.ON’s offer is 28% greater than the Offer Price submitted by Gas Natural. E.ON’s offer is all in cash, which makes it easier for ENDESA’s shareholders to make a decision with respect to the offer. The Board of Directors of ENDESA, S.A. has made a preliminary assessment of E.ON’s offer and will make a formal recommendation when such offer is approved by the CNMV. Conclusion: Taking into account the foregoing, the Board of Directors unanimously recommends that ENDESA, S.A.’s shareholders reject the Gas Natural Offer and do not tender their ENDESA Ordinary Shares or ENDESAADSs pursuant to the Gas Natural Offer.

The Board received reports to support and reaffirm its opinion from ENDESA’s financial advisors: Citigroup Global Markets Limited, Deutsche Bank AG London, J.P. Morgan Plc, Lehman Brothers (Europe) Limited and Merrill Lynch Capital Markets España, S.A., S.V., who share a negative opinion of the Offer Price and believe that it is inadequate, from a financial standpoint, for ENDESA shareholders. Existence of Agreements between the Company and the Offeror No agreement exists between the Company and the Offeror with regard to the Offer. Existence of Agreements between the Offeror and the Members of the Board of Directors of ENDESA No agreement exists in connection with the Offer between the Offeror and any member of ENDESA’s Board of Directors. Individual Opinion of the Members of the Board of Directors of ENDESA None of the members of the Board of Directors of ENDESA, present or represented, at the meeting of 7 March 2006, expressed an individual opinion with regard to the Offer different than the one taken collectively and which has been described under items 1 and 2 of this document. Juan Ramón Quintás Seoane did not attend this Board Meeting due to a potential conflict of interest because he is the Chairman of the Spanish Confederation of Savings Banks and, therefore, has not stated his position with regard to the Gas Natural Offer. Intention to Tender of the Members of the Board of Directors of ENDESA None of the members of the Board of Directors of ENDESA, present or represented, at the meeting it held on 7 March 2006, who hold, directly or indirectly, ENDESA shares intend to tender any of their shares pursuant to the Offer. Juan Ramón Quintás Seoane, due to the reason explained in item 5, did not attend this Board Meeting and has not informed ENDESA as to whether he intends to tender his 1,525 shares of ENDESA pursuant to the Offer. Caja de Ahorros y Monte de Piedad de Madrid has expressly informed ENDESA through Miguel Blesa de la Parra that it does not intend to sell its shares pursuant to the Offer. The following table specifies the number of ENDESA shares held, directly or indirectly, by the members of the Board of Directors, as well as the equivalent percentage of the Company’s capital held, directly or indirectly: Percentage Members of the Board Number of Direct and of Directors of Shares Indirect Shares (%) Manuel Pizarro Moreno 100,004 0.00944 Rafael Miranda Robredo 7,585 0.00071 Alberto Alonso Ureba – – Miguel Blesa de la Parra 600 0.00005 José María Fernández Cuevas – – José Manuel Fernández-Norniella – – Rafael González-Gallarza Morales 3,300 0.00031 Juan Ramón Quintas Seoane 1,525 0.00014 Francisco Javier Ramos Gascón 9,771 0.00092 Alberto Recarte García-Andrade 21,350 0.00201 Manuel Ríos Navarro 12,472 0.00117 Juan Rosell Lastortras 10,005 0.00094 José Serna Masiá 17,496 0.00165 TOTAL 184,108 0.01734 To approve, in compliance and accordance with U.S. securities law, Schedule 14D-9 which contains ENDESA S.A.’s recommendation on the takeover offer for ENDESA S.A. and its ADS by Gas Natural, SDG, S.A. in the U.S. To empower the Chief Executive Officer, Rafael Miranda Robredo, and General Secretary and Secretary to the Board of Directors, Salvador Montejo Velilla, individually to ensure the relevant documents are delivered to the securities markets regulators, both national and foreign, as well as distributed in accordance with the terms set out under current regulation and in the manner which best serves the Company’s interests. At the meeting held on 31 March 2006, the Board of Directors unanimously adopted the following resolutions: To deposit with the Madrid Mercantile Court nº 3 a Euro 1 billion bond for the injunction granted to suspend Gas Natural’s takeover offer for ENDESA. To publicly disclose, following notification to the CNMV, the following resolution: “With regard to the ruling of 21 March 2006 made by the Madrid Mercantile Court Number 3 on Appeal 523/05, which places an injunction on the takeover bid presented by Gas Natural and the execution of a contract signed between Gas Natural and Iberdrola regarding the sale of ENDESA assets, and after carrying out an indepth study of the legal implications of the ruling and its impact on the takeover process currently faced by the Company, ENDESA’s Board of Directors, in the interest of the Company and its shareholders, has unanimously agreed to: 1. To accept the ruling, which recognises as plausible the opinion put forward on repeated occasions by ENDESA with regard to the serious legal problems posed by the takeover bid launched by Gas Natural and specifically its agreement with Iberdrola, as such represents collusio by

the two companies the objective or effect of which is likely the elimination of ENDESA as a competitor and the division of its assets between them. 2. To consider that the injunction placed on Gas Natural’s takeover bid does not affect the ongoing bidding process for the Company, given the existence of a rival bid and its authorisation process, pursuant to the criteria set out by the CNMV in its Information Memo dated 24 March 2006. 3. To assume that amount of the bond neither determines or prejudices the existence or amount of any potential liabilities that could derive from this process, as long as there are no reasons for such. 4. To deposit the Euro 1 billion bond stipulated in the ruling to proceed with the injunction, while also taking legal action to appeal against the amount, which is considered to be clearly disproportionate. 5. To make the most opportune decisions at all times, including those regarding precautionary measures, to protect our shareholders’ interests first and foremost, as the process of the takeover bid for the Company runs its course and in the event of any other circumstance arising that might affect the current situation. The Board further reserves the right to claim any damages corresponding to ENDESA against Gas Natural and Iberdrola, in the event that the existence of an illegal agreement between the two companies is confirmed.” At its meeting on 12 May 2006, the Board of Directors unanimously agreed to appoint José Serna Masía as Chairman of the Audit and Compliance Committee and Manuel Ríos Navarro as Chairman of the Appointments and Compensation Committee. Pursuant to the ruling of 28 April 2006 issued by the Administrative Division of the Supreme Court on case 47/2006, the Board of Directors resolved unanimously at its meeting of 23 May 2006 to deposit a Euro 1 billion bond within one month, bearing in mind that under the ruling, the bond may be deposited with the Madrid Mercantile Court Nº 3 as long as the bonding institutions in that process express their willingness to grant this item the effects of the bond presented. On 7 August 2006, the Board of Directors studied the National Energy Commission’s ruling of 27 July, in which it imposed 19 conditions on E.ON for its acquisition of a stake in ENDESA’s capital stock following a settlement of the takeover bid presented before the Spanish National Securities Market Commission. Pursuant to the corresponding legal opinion, according to which the filing of appeals against the National Energy Commission’s ruling is compatible with the passivity rule required of Directors under takeover rules, the Board of Directors resolved unanimously to file the pertinent appeals against the abovementioned ruling on behalf of ENDESA shareholders, concluding that the conditions imposed by the Commission on E.ON were unjustified. The Board also resolved to notify the CNMV of a relevant event that reads as follows: “Upon proper counsel, ENDESA’s Board of Directors has unanimously resolved to appeal against the resolution adopted by the National Energy Commission on 27 July in defence of the Company’s value and in the interests of its shareholders.” On 24 October, 2006, the Board of Directors studied the situation prompted by a potential approval by the CNMV of the E.ON takeover offer and the injunctions imposed by Madrid Mercantile Court Nº 3 and the Supreme Court, and unanimously resolved “To empower the Company’s Chief Executive Officer, in the broadest terms possible, to request that the injunctions set out in the Spanish Council of Ministers’ ruling of 3 February 2006 and the execution of the Gas Natural SDG, S.A. takeover bid granted by the third circuit of the Supreme Court and the Madrid Mercantile Court Number 3, respectively, be modified or lifted once the Spanish National Securities Market Regulator authorises the rival bid presented by E.ON Zwöllfte Verwaltungs GmbH. Such would be in response to any new facts and circumstances that may affect the takeover bid processes for the Company underway if awarded, and consequently prompt changes in the material budgets considered, always in the interest of the Company and its shareholders. The Chief Executive Officer may request that the injunctions be lifted or modified with other injunctions that, excluding said risk, do not compromise the continuity of the takeover process for the Company currently underway, and may also dictate and carry out all procedural actions necessary for such.” At the same meeting, the Board of Directors unanimously agreed to adopt the following resolutions: I. To approve and have available the accounts cited under Article 216 a) of the Spanish Corporations Law, under which there is deemed to exist sufficient liquidity to distribute the amount of Euro 529,376,058.50 against 2006 earnings. II. To distribute a gross dividend of Euro 0.50 per share to ENDESA shareholders payable against 2006 earnings. III. The interim dividend will be paid on 2 January 2007 through the banks and other financial institutions to be announced at a later date.” The Board of Directors also agreed to report the following to the Spanish National Securities Market Commission (CNMV) in the form of a relevant event: “ENDESA S.A.’s Board of Directors, at its meeting of 24 October 2006, agreed to pay a gross interim dividend against 2006 earnings of Euro 0.50 per share. This dividend will be paid to ENDESA, S.A. shareholders on 2 January 2007 through the banks and other financial institutions to be announced at a later date. As a result, ENDESA shares will go ex-dividend on 2 January 2007.

This interim dividend is 63.9% higher than last January’s interim dividend charged against 2005 earnings.” On 21 November 2006, the Board of Directors unanimously approved the following report issued by ENDESA on the Takeover Bid submitted by E.ON Zwölfte Verwaltungs GmbH under Article 20 of Royal Decree 1197/1991 of 26 July, governing takeover offers: REPORT OF THE BOARD OF DIRECTORS OF ENDESA, S.A. REGARDING THE TAKEOVER OFFER MADE BY E.ON ZWÖLFTE VERWALTUNGS GMBH At its meeting of 21 November 2006, the Board of Directors of ENDESA, S.A. (“ENDESA” or the “Company”), in accordance with the provisions of Article 20 of Royal Decree 1197/1991 of 26 July governing takeover offers, approved, by unanimous vote of the directors present, the following report on the takeover offer (the “Offer”) made by E.ON Zwölfte Verwaltungs GmbH (“E.ON” or the “Offeror”) for a price of Euro 25.405 per share, which was authorised by the Spanish National Securities Market Commission (CNMV) on 16 November 2006. This report, in addition to describing the principal features of the Offer, contains the Board’s position on the Offer, as well as certain additional related information. This report does not issue an opinion regarding the increased Offer price of a minimum of Euro 35 per share that has been announced by the Offeror, which, in accordance with the provisions of Royal Decree 1197/1991, will be properly considered once it has been formalised. Principal Features of the Offer According to the Prospectus relating to the Offer authorised by the CNMV, the following are the principal features of the Offer: Offeror The Offeror is the German company E.ON Zwölfte Verwaltungs GmbH, a wholly-owned subsidiary of the German company E.ON AG. Nature of the Offer E.ON’s Offer competes with another offer made by Gas Natural SDG, S.A., which the CNMV authorised on 27 February 2006. Securities Covered by the Offer The Offer covers the 1,058,752,117 shares of ENDESA with a par value of Euro 1.2 each, representing 100% of its capital stock. Consideration According to the Prospectus authorised by the CNMV, E.ON offers as consideration for each ENDESA share a full-cash price of Euro 25.405. Nevertheless, the Prospectus refers to the E.ON’s commitment, announced in its disclosure of 26 September 2006 to the CNMV, to increase the Offer price to at least Euro 35 per share, in accordance with the offer increase procedures prescribed by Article 22 of Royal Decree 1197/1991 (in the event that Gas Natural SDG, S.A. withdraws its offer) or by Article 36.2 of the same Royal Decree (in the event that Gas Natural SDG, S.A. does not withdraw and the sealed envelope bidding process prescribed for competing offers is undertaken). The CNMV has postponed the sealed envelope bidding process until Gas Natural SDG, S.A.’s offer, which was suspended by injunctions imposed by the Madrid Mercantile Court Number 3 (ruling of 21 March 2006) and by the third circuit of the Supreme Court (Decision of 28 April 2006), has resumed. The CNMV will promptly disclose the deadline for and requirements for participation in the sealed envelope bidding process once Gas Natural SDG, S.A.’s offer resumes. Period of Acceptance The CNMV has decided to postpone the beginning of the period for acceptance of E.ON’s Offer due to the above-mentioned injunctions against Gas Natural SDG, S.A.’s offer. Either in the event of the withdrawal of Gas Natural SDG, S.A.’s offer or in the presumed case that Gas Natural SDG, S.A.’s offer is eventually resumed, the CNMV will promptly disclose to the market, through a relevant event disclosure, the firm date on which the acceptance period of the Offer will begin. Once the Offer’s acceptance period begins, it will run for one month, although this period may be extended by the CNMV to allow ENDESA’s General Shareholders’ Meeting to adopt the bylaw amendments upon which the Offer is conditioned (see Section 1.6 below). Furthermore, the CNMV may take other measures to ensure that the periods of acceptance for the Offer and for the offer made by Gas Natural SDG, S.A. conclude at the same time. Conditions of the Offer The effectiveness of E.ON’s Offer is conditioned upon the acquisition of a minimum of 529,481,934 ENDESA’s shares, representing 50.01% of its capital stock. Furthermore, the Offer is conditioned both upon ENDESA’s General Shareholders’ Meeting making certain amendments to the Bylaws and upon those amendments being registered on the Mercantile Registry. Specially, the Offer is conditioned upon the elimination of all limitations or restrictions on the number of votes that can be exercised by ENDESA shareholders (Article 32 of the Bylaws), the removal of requirements concerning the composition of the Board of Directors and the type of Board members, with the corresponding removal of the restriction on the number of terms to which certain types of Board members may be elected (Articles 37 and 38 of the Bylaws), and the removal of all qualifications, except for those concerning the absence of legally-prohibited conflicts of interest, on the appointment of a member of the Board of Directors or of a Managing Director (Article 42 of the Bylaws), all described in full in the Prospectus.

Board of Directors’ Opinion of the E.ON Offer ENDESA’s Board of Directors, by unanimous vote of those present, confirms its preliminary assessment of the Offer, which was issued on 21 February, 2006, in response to the announcement of the Offer. Accordingly, and without prejudicing its position set out below on price, the Board views positively the fact that the Offer is made entirely in cash, unlike the competing offer made by Gas Natural SDG, S.A., improving the consideration proposed pursuant to this. In addition, the Board views as positive the Offeror’s intentions, as explained in the Prospectus, to maintain ENDESA’s industrial project, particularly its investment plan and its staff, as well as its goal of furthering the development of the Spanish gas and electricity markets. Nevertheless, ENDESA’s Board of Directors, also by unanimous vote, recommends not accepting the Offer at its current price of Euro 25.405 per share, given the Offeror’s irrevocable commitment to raise the price to a minimum of Euro 35 per share. It is made expressly clear that this report issued by ENDESA’s Board of Directors does not address the increased Offer price announced by the Offeror, which will be properly considered in accordance with the provisions of Royal Decree 1197/1991 once it has been formalised by E.ON, either in accordance with the normal offer increase procedure in the event that Gas Natural, SDG, S.A. withdraws its offer or, otherwise, in accordance with the sealed envelope bidding process prescribed for competing offers. ENDESA’s Board of Directors has received the opinion of its financial advisors: Citigroup Global Markets Limited, Deutsche Bank AG London, J.P. Morgan Plc, Lehman Brothers (Europe) Limited and Merrill Lynch Capital Markets España, S.A., S.V. Conduct of the Company with respect to the Conditions Affecting the Takeover Offer Process The Board of Directors would like to note that, as announced in its disclosure of 16 November 2006 to the CNMV, ENDESA has petitioned the Supreme Court to modify or lift the injunction on both the Spanish Council of Ministers’ ruling of 3 February 2006 and the competing bid made by Gas Natural SDG, S.A. Similarly, ENDESA has petitioned the Madrid Mercantile Court Number 3 to lift the injunction against the execution of Gas Natural SDG, S.A’s offer. Moreover, ENDESA’s Board of Directors intends to call, at the appropriate time, a General Shareholders’ Meeting to decide whether to adopt the Bylaws amendments upon which both Gas Natural SDG, S.A. and E.ON have conditioned their respective offers. Existence of Agreements between the Company and the Offeror No agreement whatsoever exists between the Company and Offeror in connection with the Offer, with the exception of the confidentiality agreement made on 16 January 2006 and described in Section 1.8.1 of the Prospectus. Agreements between the Offeror and Members of ENDESA’s Board of Directors No agreement whatsoever exists in connection with the Offer between the Offeror and any of the members of ENDESA’s Board of Directors. Individual Opinions of the Members of the ENDESA Board of Directors None of the members of ENDESA’s Board of Directors who attended or were represented at the Board meeting of 21 November 2006, has expressed an individual opinion of the Offer separate from the Board’s collective opinion, which appears in Section 2 above. Juan Ramón Quintás Seoane did not attend the above-mentioned Board meeting due to a potential conflict of interest related to his position as Chairman of the Spanish Confederation of Savings Banks and, therefore, has not stated his position on the Offer. Intention of Board Members who Hold ENDESA Shares to Accept the Offer None of the members of the Board of Directors who attended or were represented at the Board meeting of 21 November 2006 and who directly or indirectly hold ENDESA shares intends to tender his shares in acceptance of the Offer at its current price of Euro 25.405 per share. Caja de Ahorros y Monte de Piedad de Madrid, through Miguel Blesa de la Parra, has expressed its intention not to accept the Offer at the current price of Euro 25.405 per share with respect to the ENDESA shares it owns, given the Offeror’s commitment to raise the Offer price to a minimum of Euro 35 per share, which will be considered at the appropriate time. Juan Ramón Quintás Seoane, for the reason mentioned in Section 5 above, did not attend the above-mentioned Board meeting and has not stated his intention with respect to whether he will accept the Offer for the 1,525 ENDESA shares that he holds. The following table indicates the number of ENDESA shares that each member of the Board of Directors holds, directly or indirectly, as well as the percentage of the total share capital that each direct and indirect stake represents:

At its 23 January 2007 meeting, the Board of Directors unanimously approved the document “ENDESA’s greater value. FY2006 forecasts and 2009 targets,” which includes ENDESA’s forecast 2006 earnings and updated targets for 2009, ensuring the market has the most recent figures available. Those present or represented at the Board meeting also unanimously approved the U.S. announcement, on a Schedule 14D-9 form, of ENDESA S.A.’s recommendation on the takeover offer for ENDESA’s shares and ADS’ presented in Spain by E.ON Zwölfte Verwaltungs GmbH, S.A., a subsidiary of E.ON AG, under the terms set out in the takeover offer report that the Board of Directors had approved at its 21 November 2006 meeting in accordance with Article 20 of Royal Decree 1197/1991 of 26 July, governing takeover offers, in view of the imminent filing of the U.S. prospectus (which did not address the increase in price announced) and in accordance with U.S. securities market regulations. Pursuant to Schedule 14D-9, Item 7 “Purposes of the transaction and plan or proposals,” the Board also decided that, at that time and absent any legal requirement to make such known, the inclusion of any additional information concerning any potential alternatives under consideration in that section (as also described in the Schedule 14D-9 for the Gas Natural takeover bid), particularly regarding any potential terms or the identity of third parties, may be detrimental to the interests of ENDESA and its shareholders. The Board of Directors also agreed to empower Chief Executive Officer Rafael Miranda Robredo to sign and file the Schedule 14D-9, Item 4 of which, “The solicitation or recommendation,” required the Board of Directors’ recommendation in the 21 November 2006 report to ensure the Schedule 14D-9 included any facts and circumstances that may have arisen or become known as of the time of its filing, and ensure the Schedule is delivered to the securities markets regulators, both national and foreign, and distributed in accordance with the terms set out under current regulation and in the manner which best serves the Company’s interests.

This report, in addition to describing the principal features of the Offer, as amended, contains the Board’s position on the Offer, as well as certain additional related information. Principal Features of the Offer According to the Prospectus relating to the Offer authorised by the Spanish National Securities Market Commission (CNMV), the following are the principal features of the Offer: Offeror The Offeror is the German company E.ON Zwölfte Verwaltungs GmbH, a wholly owned subsidiary of the German company E.ON AG. Nature of the Offer E.ON’s Offer, which was authorised by the CNMV on 16 November 2006, was filed as a competing Offer with respect to the public tender offer filed by Gas Natural SDG, S.A., which was authorised by the CNMV on 27 February 2006.

Opinion of the Board of Directors on the E.ON Tender Offer ENDESA’s Board of Directors, by unanimous vote of the Directors present, views as positive the terms of the Offer and recommends to the shareholders that they tender their shares pursuant to the Offer for the following reasons: 1. It fairly reflects the value of the Company and incorporates a price improvement of Euro 1.25 per share over the most recent price offered by E.ON. 2. The consideration being offered by E.ON consists entirely of cash, and E.ON’s offer is being made for 100 percent of ENDESA’s shares. 3.

E.ON’s offer is the only offer that complies with all current legal requirements and that is fully supported by the legal and financial guarantees that ensure its viability. It is also the only offer for which all required authorisations have been obtained.

Branch in Spain, Citigroup Global Markets Limited, Deutsche Bank AG London Branch, J.P. Morgan Plc, Lehman Brothers (Europe) Limited and Merrill Lynch Capital Markets España, S.A., all of which state that the consideration offered by E.ON is fair to ENDESA’s shareholders from a financial point of view.

FUNCTIONING OF THE SHAREHOLDERS’ MEETING On 19 June 2003, the General Shareholders’ Meeting of ENDESA, S.A., in compliance with the provisions of the Corporate Bylaws, approved its Regulations at the proposal of the Board of Directors of ENDESA, S.A., in order to facilitate Shareholder participation at the Shareholders’ Meeting. These regulations were amended on 2 April 2004. The Regulations regulate, in conformity with statutory provisions and the Bylaws, the organisation and functioning of the Shareholders’ Meeting, its call notices, preparation, information, attendance and proceedings, in order to make it easier for Shareholders to exercise their rights. Following is a summary of the most relevant aspects of the rules governing the functioning of the Shareholders’ Meeting as included in these Regulations: Classes. The Shareholders convened in a duly called Shareholders’ Meeting decide by majority on matters specific to the jurisdiction of the Meeting. All Shareholders are subject to the resolutions passed at the Meeting, including dissenting Shareholders and those who have not taken part in the Meeting. Shareholders’ Meetings may be annual or extraordinary. An Annual Shareholders’ Meeting, previously called for such purpose, must be held within the first six months of each fiscal year to scrutinise the conduct of business, approve, as the case may be, the prior year’s financial statements and rule on the appropriation of income or allocation of loss. Any Meeting other than as provided for in the preceding paragraph will be deemed to be an Extraordinary General Shareholders’ Meeting. Powers. The Shareholders’ Meeting is the competent body for ruling on all matters it is obliged to rule on by Law or under the Corporate Bylaws and, in general, for adopting all resolutions relating to its function as the Company’s supreme body. Call notices. The Board of Directors will call an Annual Shareholders’ Meeting to be held within the first six months of each fiscal year and an Extraordinary Shareholders’Meeting whenever it so deems appropriate for the interests of the Company. The Board of Directors must also call a Shareholders’ Meeting if Shareholders holding at least 5 percent of the capital stock so request, stating in the request the business to be transacted at that Meeting. In this case, the Shareholders’ Meeting must be called to be held within thirty days following the date on which notice of the request to call it is served by a notary. The Board of Directors will draw up the agenda, which must include the business requested. Without prejudice to the above, if there is a situation which, in the opinion of the Chairman of the Board of Directors or his/her substitute, is of singular importance to the Company and its Shareholders, the Chairman, or his/her substitute, may call an Extraordinary Shareholders’ Meeting to analyse the situation in question and, if necessary, adopt the pertinent resolutions. Right to information. As soon as the call notice of the Shareholders’ Meeting is served, any Shareholder may, immediately and free of charge, obtain from the Company at its registered office, the financial statements, the proposed appropriation of income or allocation of loss, the management report and the auditors’ report. Shareholders may also inspect at the registered office the proposed resolutions, reports and other documentation required to be made available by Law. In such cases as may be legally applicable, the Shareholders may also request that the full wording of the documents be made available to them and delivered or sent to them free of charge. Shareholders may request in writing, prior to the Shareholders’ Meeting, any reports or clarifications as they may deem necessary regarding the items included on the agenda. The Directors will be obliged to furnish them with any such reports or clarifications, unless, in the opinion of the Chairman, the public disclosure of the data requested would harm the Company’s interests. This exception will not apply if the request is supported by Shareholders representing at least one quarter of the capital stock. Right to attend. Shareholders who, individually or grouped together with others, hold at least 50 shares, may attend Shareholders’ Meetings provided that they have registered their shares in the appropriate book entry accounting record five days before the Meeting is held and they obtain the relevant attendance card. Representation by proxy. Any Shareholder who has the right to attend, without prejudice to the provisions of the Law concerning cases of family representation or the grant of general powers of attorney, may be represented at a Shareholders’ Meeting by another person. Proxies must be granted in writing and especially for each Shareholders Meeting. In any event, whether in the case of voluntary proxies or legal proxies, not more than one proxyholder can attend a Meeting. A proxy can be revoked at any time. Personal attendance at the Shareholders’ Meeting by the grantor of a proxy will be deemed to constitute a revocation of the proxy. Convening Meetings. The Shareholders’ Meeting will be validly convened on first call if the Shareholders present in person or by proxy hold at least 25 percent of the subscribed voting capital stock. At second call, the Meeting will be validly convened regardless of the capital stock attending it. Debenture issues, capital increases or reductions, changes in the legal form, or the merger or spin-off, of the Company and, in general, any amendment to the Corporate Bylaws will

require at first call the attendance in person or by proxy of Shareholders holding at least 50 percent of the subscribed voting capital stock. At second call, the attendance of 25 percent of that capital stock will suffice. Chairman and Presiding Panel. Shareholders’ Meetings will be chaired by the Chairman of the Board of Directors who will be assisted by a Secretary, who will be the Secretary of the Board of Directors. The Presiding Panel will be composed of the Board of Directors. List of attendees. Attendance cards and proxies will be accepted up to the time set for the Shareholders’ Meeting to start. Before transacting the business on the agenda, a list of attendees will be drawn up, stating the nature or representative capacity of each and the number of shares, held by them or third parties, with which they attend. Proceedings. Once the list of attendees has been drawn up, the Chairman will declare the Meeting to be validly convened and then allow the Notary to take the floor to ask the attendees if they have any reservations concerning or objections to the data disclosed or to the valid convening of the Meeting, indicating that whoever wishes to express such reservations or raise such objections must do so by making a statement in the presence of the same Notary so that it can be duly noted in the Minutes of the Meeting. The Chairman will invite Shareholders who wish to participate in the Meeting to request information or propose resolutions regarding the items on the agenda or to make any other statement so that, in the presence of the Notary, they can have their request, proposed resolutions or statement duly noted after indicating their personal particulars and the number of shares held by them or, as the case may be, represented by them. The Chairman of the Meeting and such persons as he/she may designate for the purpose will address the attendees to present their respective reports. Then, the Chairman will invite Shareholders who have so requested to take the floor, after determining the order in which they are to be called to do so. Each Shareholder will initially have five minutes on the floor, although the Chairman of the Meeting may extend the time allotted. During the time allotted to them, the Shareholders may request such reports or clarifications as they deem necessary regarding the items on the agenda. The Chairman is responsible, under Law, for furnishing the information requested, although he/she may deem it appropriate due to the nature of the information, entrust this function to the Managing Director, to any member of the Presiding Panel or any other expert as he/she may consider suitable. If the information requested is not available at the Meeting, it will be made available to the Shareholders at the registered office of the Company within 7 days following the date on which the Meeting was held. Also, in light of the proposed resolutions delivered to them before the start of the Meeting, Shareholders may, while speaking on the floor, submit alternative proposals on any item on the agenda, except in cases where by law they must be available to the Shareholders at the registered office when the call notice is published. In addition, while speaking on the floor they may propose the adoption of resolutions on business which does not have to be stated on the agenda for the Meeting in order to be debated and decided on by the Meeting. Shareholders who wish to have their entire speech on the floor noted in the Minutes must expressly make a request to this effect and deliver to the Notary, before taking the floor, the written transcript of their speech so that it can be verified and subsequently attached to the original Minutes. Lastly, the different proposed resolutions to be adopted by the affirmative vote of the majority of the voting capital stock attending the Meeting in person or by proxy will be put to a vote, subject to the qualified quorums for convening and voting at Meetings established in the Law and in the Corporate Bylaws. If proposals have been submitted on business that does not have to be stated on the agenda for the Meeting to be resolved, the Chairman will decide on the order in which these business items are to be put to a vote. Otherwise, the resolutions will be adopted pursuant to the agenda set forth in the call notice. After they have been read out by the Secretary, a step which can be dispensed with if no Shareholder opposes this, the proposed resolutions which have been submitted by the Board of Directors will first be put to the vote and, if appropriate, those submitted by others will be voted on pursuant to an order of priority in time. In any event, once a resolution has been approved, all those relating to the same item of business and which are incompatible with it will fail automatically and, therefore, will not be put to vote. To adopt resolutions, the following system for determining votes will be used: a) In the case of resolutions on items included on the agenda, the votes corresponding to all the shares attending the Meeting, whether in person or by proxy, less the votes corresponding to the shares the holders or proxyholders of which inform the Notary by written notice or a personal representation of their vote against, or blank vote or abstention, will be deemed to be votes for the proposal put to a vote. b) In the case of resolutions on items not included on the agenda, the votes corresponding to all the shares attending the Meeting, whether in person or by proxy, less the votes corresponding to the shares the holders or proxyholders of which inform the Notary by written notice or personal representation of their vote for, blank vote or abstention, will be deemed to be votes against the proposal put to a vote. For the purposes of the two procedures described above, shares which appear on the list of attendees less those of

holders or proxyholders who have absented themselves from the Meeting before the voting and have placed this circumstance on record in the presence of the Notary, will be deemed to be shares attending the Meeting. Notwithstanding the provisions stated above, and having regard to the circumstances prevailing in each case, the Presiding Panel may resolve that in order to adopt resolutions any other system for determining votes that permits verification that the affirmative votes necessary for their approval have been obtained and recording the result of the voting in the Minutes be used. Whatever the system used to determine the voting, verification by the Presiding Panel of the Meeting that there is a sufficient number of affirmative votes to attain the necessary majority in each case will permit the Chairman to declare the proposed resolution in question approved. Once voting on the proposed resolutions has finished, the Meeting will conclude and be adjourned by the Chairman. Voting and proxies by remote means of communication. Shareholders entitled to attend and vote may cast their votes on proposals relating to business on the agenda, by mail or by electronic communication, as provided for in the Corporate Bylaws, in the Shareholders’ Meeting Regulations, and in such supplemental and implementing provisions as may be established by the Board of Directors. Votes delivered by mail will be cast by sending to the Company the attendance card issued by it or by entities charged with keeping the book-entry record, without prejudice to any other requirements or conditions that may be imposed by the Board of Directors. Votes by electronic communication will be cast by using a qualified electronic signature and any other kind of safeguard seen fit by the Board of Directors to ensure the authenticity and identity of the Shareholder exercising the right of vote, also without prejudice to any other requirement or condition that may be imposed by the Board of Directors. Votes cast by either means must be received by the Company 24 hours before the date and time set for the Shareholders’ Meeting at first call. Otherwise, the vote will be deemed not to have been cast. Shareholders with the right to attend and who cast their votes by remote means pursuant to the conditions described will be deemed to be present for the purpose of convening the Shareholders’ Meeting in question. The above-mentioned provisions for casting votes by remote means of communication will also apply to the granting of proxies by Shareholders for the Shareholders’ Meeting by electronic communication or by any other remote means of communication. Attendance in person by a Shareholder at the Shareholders’ Meeting will have the effect of revoking any vote cast by post or electronically. Attendance in person by the grantor of the proxy at the Shareholders’ Meeting will also have the effect of revoking the proxy granted by e-mail or by any other means of remote communication provided for in the Shareholders’ Meeting Regulations. Minutes. The Minutes of the Meeting will be drawn up by a Notary and need not be approved by attendees. For such purposes, the Board of Directors will resolve to request a Notary of its choice to draw up the Minutes. Limitations on voting rights. Shareholders will be entitled to one vote for each share that they hold or represent, except for non-voting shares, which will be governed by the provisions of Article 8 of the Corporate Bylaws. As an exception to the provisions described above, no Shareholder may, in relation to the shares held, cast a number of votes which is higher than that corresponding to 10 percent of the total voting capital stock existing at any given time even if the shares held exceed 10 percent. To compute the maximum number of votes that each Shareholder can cast the shares held by each must be included, but shares corresponding to other Shareholders who have granted a proxy to that Shareholder will not be included, without prejudice to the same 10 percent limit on votes corresponding to the shares held by each Shareholder granting a proxy also applying to them individually. The limitation described in the preceding paragraphs will also apply to the maximum number of votes which can be cast by two or more corporate stockholders belonging to the same group of entities, whether jointly or separately, as well as to the maximum number of votes which can be cast by an individual stockholder and any stockholding entity or entities controlled by that individual, whether jointly or separately. For the purposes stated in the preceding paragraph, to consider whether a group of entities exists, regard will be paid to the provisions of the current Securities Market Law of July 28, 1988, and it will be deemed that an individual controls one or more entities if, in the relationship between+ that individual and the entity or entities in question, any of the circumstances of control that a controlling entity is required to have under the aforementioned Law with respect to its controlled entities exists. Likewise, the relationship between any individual or corporate Shareholder and interposed, fiduciary or like persons or entities that are in turn Shareholders of the Company, as well as funds, investment institutions or similar entities that are also Shareholders of the Company, or other Shareholders through voting trust agreements, will be equated to the relationship of control in Article 4 of the Securities Market Law if the exercise of the voting rights attaching to the shares held by such persons or entities is determined directly or indirectly by the Shareholder in question. Shares that belong to the same holder, to a group of entities or to an individual or legal entity, and to entities controlled by such individual or legal entity, will be fully computable among

the shares attending the Shareholders’ Meeting to achieve the capital stock quorum necessary to validly convene the Meeting, but at the time of voting the established limit of 10 percent on the number of votes will apply to these. Extension and suspension. At the proposal of the Presiding Panel or at the request of Shareholders representing one quarter of the capital present at the Shareholders’ Meeting, the attendees may resolve to extend the Meeting for one or more consecutive days. Once the Meeting has been extended, compliance with the requirements imposed by Law or under the Corporate Bylaws for it to be validly convened need not be repeated at successive sessions. If any Shareholder included on the list of attendees drawn up at the start of the Meeting does not attend the successive sessions subsequently, the majorities necessary to adopt resolutions will continue to be determined at those sessions according to data from that list. Exceptionally, if there are disturbances that substantially interrupt the proper order of the Meeting or there is any other extraordinary circumstance that temporarily hinders its normal conduct, the Presiding Panel may resolve to suspend the session for an appropriate time, but never for longer than two hours, in order to restore the conditions necessary for it to continue. In this case, the Chairman may adopt such measures as he/she deems fit to ensure the safety of those present and avoid the repetition of circumstances that may further disrupt the proper order of the Meeting. If, after the Meeting has resumed, the circumstances that gave rise to the temporary suspension persist, the Chairman may ask the Board of Directors, if an absolute majority of its members is sitting on the Presiding Panel of the Meeting, to propose to the attendees that the Meeting be extended until the following day. If the extension is not, or cannot, be approved, the Meeting will be adjourned immediately. Disclosure. Regardless of the disclosure measures required by Law or under Company bylaws for each case, the Shareholders may apprise themselves of the resolutions adopted by the Shareholders’ Meeting on the Company’s website, on which the full wording of these resolutions will be posted.

The safeguards deemed appropriate by the Board of Directors, pursuant to Article 20 bis of the Shareholders’ Meeting Regulations, to ensure the authenticity and identity of the Shareholder granting the proxy are a qualified electronic signature and an advanced electronic signature, as provided for in Electronic Signature Law 59/2003, where they are based on a qualified electronic certificate for which there is no record of its revocation and which has been issued by the Spanish Public Certification Authority (CERES), which reports to the Spanish Mint. All shareholders who have an electronic signature that meets the requirements indicated and who identify themselves by that signature, and all shareholders holding an electronic identity card (e-ID) may grant a proxy by going to the Company’s website at www.endesa.es and following the procedure established there. Shareholders granting proxies by electronic means must notify the designated proxyholder of the proxy that has been granted. Where a proxy is granted to any Director or to the Secretary of the Board of Directors of ENDESA, such notice is deemed to have been served upon receipt by ENDESA of the electronic proxy. On the date and at the venue of the Meeting, the designated proxyholders must identity themselves with their national identity card or passport, if appropriate together with a copy of the electronic proxy, so that the Company can check the proxy granted to them. The proxyholder can only exercise the shareholder’s vote by attending the Meeting in person. (ii) Mail: To grant postal proxies, Shareholders must fill out and sign the “Proxies” section on the attendance card, issued on paper by the relevant entity participating in IBERCLEAR. The proxyholder can only exercise the vote by attending the Shareholders’ Meeting in person. Shareholders may send the duly completed and signed card: 1. By postal mail to the following address: ENDESA, S.A. (GENERAL SHAREHOLDERS’ MEETING), CALLE RIBERA DEL LOIRA, 60, 28042 MADRID. 2. Using the “prepaid” envelope, if any, accompanying the card. 3. By a courier service equivalent to the postal service to the address indicated above. 4. By delivering the completed and signed card to the entity participating in IBERCLEAR at which they have deposited their shares. On the date and at the venue of the General Shareholders’ Meeting, the designated proxyholders must identity themselves with their national identity card or passport, if appropriate together with a copy of the proxy, so that the Company can check the proxy granted to them. BASIC RULES ON REMOTE VOTING AND PROXIES Deadline for receipt by the Company of votes cast and proxies granted remotely In order to be valid and to comply with the Shareholders’ Meeting Regulations, remote voting and proxies (electronic or postal) must be received by the Company 24 hours before the date and time set for the Shareholders’ Meeting at first call. Otherwise, the proxy will deemed not to have been granted and the vote not to have been cast, unless their later receipt prior to the holding of the General Shareholders’ Meeting allows all due checks and calculations for preparing and holding the Meeting to be performed. Rules of preference between proxies, remote voting and attendance in person at the Meeting Priorities between proxies, remote voting and attendance in person (i) Personal attendance at the General Shareholders’Meeting by shareholders who have granted a proxy or already cast their remote vote, by whichever means, will render the proxy or vote cast remotely ineffective. (ii) Likewise, whichever means was used to cast it, a vote will render any proxy granted electronically or by means of a printed card ineffective, and the proxy will be deemed to have been revoked if granted previously, or not to have been granted at all if granted subsequently. Priorities between proxies Should a Shareholder validly grant several proxies, the last one received by the Company will prevail. Priorities between votes cast remotely A Shareholder may validly vote remotely once only for each securities position. Should a Shareholder cast several votes remotely for the same shares, whether electronically or by mail, the first one received by the Company will prevail, rendering those received subsequently invalid. Only by attending the General Shareholders’ Meeting personally can the Shareholder revoke or change his/her vote if cast remotely. Indication of remote vote Shareholders who wish to vote remotely (whether electronically or by post) must indicate the direction of their vote for each item of business included on the agenda. Should a

shareholder fail to indicate the direction of his/her vote for any of the items of business on the agenda, such shall be understood as a vote in favour of the proposals of the Board of Directors on the business included on the agenda drafted, and against all other proposed resolutions included on the accompaniment to the agenda, if applicable, pursuant to Article 97.3 of the Corporations Law. Other provisions Where electronic means are used, only one electronic action may be performed for each type of operation (one vote and one proxy). Both proxies conferred and votes cast remotely will be rendered void if the shares conferring the right of attendance are disposed of and the Company is apprised thereof. The safekeeping of electronic signatures for voting or granting proxies by electronic means is the sole responsibility of Shareholders. Special rules Shareholders who are legal entities or who are not resident in Spain must contact the Shareholder Information Hotline on 900 666 900 to ascertain whether the mechanisms for remote voting and proxies can be adapted to their specific circumstances, with the due safeguards. Likewise, if the Shareholder is a legal entity, it must notify the Company of any modification or revocation of the powers held by its representative and, therefore, ENDESA accepts no liability whatsoever until such notice is served. TECHNICAL INCIDENTS ENDESA reserves the right to modify, suspend, cancel or restrict the mechanisms for electronic voting and proxies where technical or security reasons so require. ENDESA shall accept no liability for any loss incurred by Shareholders as a result of breakdown, overload, line failure, connection fault, postal service malfunctioning, or any other eventuality of the same or a similar nature beyond the control of ENDESA and preventing the use of the remote voting and proxy mechanisms.

As an exception to the provisions of the preceding sentence, no Shareholder may, in relation to the shares held by him/her, cast a number of votes higher than that corresponding to 10 percent of the total voting capital stock existing from time to time even if the shares held by him/her exceed 10 percent.

To compute the maximum number of votes that each Shareholder can cast and for the purposes of the foregoing provision, the shares held by each of them must be included, but shares corresponding to other Shareholders who have granted a proxy to that Shareholder will not be included, without prejudice to the same 10 percent limit on votes corresponding to the shares held by each of the Shareholders granting a proxy also applying to them individually. The limitation described in the preceding paragraphs will also apply to the maximum number of votes which can be cast by two or more corporate Shareholders belonging to the same group of entities, whether jointly or separately, as well as to the maximum number of votes which can be cast by an individual Shareholder and any shareholding entity or entities controlled by that individual, whether jointly or separately. For the purposes stated in the preceding paragraph, to consider whether a group of entities exists, regard must be had to Article 4 of the current Securities Market Law of July 28, 1988, and it will be deemed that an individual controls one or more entities if, in the relationship between that individual and the entity or entities in question, any of the circumstances of control that a controlling entity is required to have under Article 4 of the aforementioned Law with respect to its controlled entities exists. Likewise, for the purposes of this Article, the relationship between any individual or corporate Shareholder and interposed, fiduciary or like persons or entities that are in turn Shareholders of the Company, as well as funds, investment institutions or similar entities that are also Shareholders of the Company, or other Shareholders through voting trust agreements, will be equated to the relationship of control in Article 4 of the Securities Market Law if the exercise of the voting rights attaching to the shares held by such persons or entities is determined directly or indirectly by the Shareholder in question. The Chairman of the Board of Directors may request any Shareholder, in the days prior to the date for holding the Shareholders’ Meeting on first call, to notify the Company through its Chairman, within not more than 48 hours, of the shares held by him/her directly and held by other persons or entities controlled directly or indirectly by the Shareholder in question, and the Chairman may make such comments as he/she sees pertinent when the Shareholders’ Meeting is convened to ensure compliance with the Bylaws in relation to the exercise of voting rights by the Shareholders. Shares that belong to the same holder, to a group of entities or to an individual or legal entity, and to entities controlled by such individual or legal entity, will be fully computable among the shares attending the Shareholders’ Meeting to achieve the capital stock quorum necessary to validly convene the Meeting, but at the time of voting the limit of 10 percent on the number of votes established in this Article will apply to them. The affirmative vote of more than 50 percent of the subscribed voting capital stock at the relevant Shareholders’ Meeting, on either first or second call, shall be required to amend this Article.”

OTHER EXTERNAL DIRECTORS Name or Corporate Name of Director Committee Proposing Appointment JOSÉ M. FERNÁNDEZ NORNIELLA APPOINTMENTS AND COMPENSATION COMMITTEE ALBERTO RECARTE GARCÍA- ANDRADE APPOINTMENTS AND COMPENSATION COMMITTEE JUAN ROSELL LASTORTRAS APPOINTMENTS AND COMPENSATION COMMITTEE Give details of the reasons why they cannot be considered nonindependent or independent Directors: As indicated in section B.1.4 below, Alberto Recarte García-Andrade and Juan Rosell Lastortras have made declarations attesting to their compliance with the criteria defined in the recommendations of the Aldama Committee and of the European Union and as such as considered external nominee Directors. In addition, Alberto Recarte García-Andrade and Juan Rosell Lastortras cannot be considered nominee Directors as their seats on the Board of Directors do not derive from an equity ownership in the Company’s capital stock, but rather personal appointment at the proposal of the Appointments and Compensation Committee and their permanence on the Board of Directors does not depend on the continued equity ownership of Company shares by any Shareholder.

Fernández Norniella was appointed Director of Endesa in July 1998 and reappointed in June 2003. Until 18 July 2006, he was considered an external independent director. Following his appointment on that date as Director of Caja de Ahorros y Monte de Piedad de Madrid, a stable shareholder with a significant stake in the capital stock of Endesa, S.A., he no longer meets the requirements to be considered an independent director. However, he also cannot be considered an external nonindependent director for the same reason as Mr. Recarte and Mr. Rosell. As a result, since 18 July 2006, Mr. Norniella must be considered a non-nominee, nonindependent external director. Indicate any variations in the status of each Director that may have occurred during the year: Name or Corporate Name of Director Date of Change Previous Status Current Status JOSÉ M. FERNÁNDEZ NORNIELLA 18/07/2006 EXTERNAL INDEPENDENT DIRECTOR OTHER EXTERNAL DIRECTOR B.1.4. Indicate whether the categorisation of the Directors in the preceding point matches the composition provided for in the Board Regulations: Pursuant to the Bylaws and the ENDESA Board Regulations, the following types of Director exist: a) Directors who are related professionally and permanently to the Company. b) Directors whose relationship with the Company is confined to their membership of the Board. c) Directors by virtue of being Shareholders. Of the total number of Directors who, from time to time, make up the Board, the Directors referred to in letter b) above will constitute the majority, provided that the number of Directors appointed pursuant to the right of the Shareholders to be represented on the Board in proportion to their ownership interests in the capital stock so permits. The above definitions of type a) and type c) Directors are substantially equivalent to the categories used earlier; however, in the definition of type b) Directors, there are certain differences in terminology from the category defined in the recommendations of the Aldama Committee and of the European Union on independent Directors; consequently, ENDESA’s type b) Directors formally made a declaration attesting to the minimum principles set forth in these recommendations, so the composition of the members of ENDESA’s Board is as indicated above.

B.1.5.

Identify, as appropriate, the conflict-of-interest status of the Company’s Directors, as provided for in Article 127 of the Corporations Law: The Directors were not subject to any conflicts of interest in 2006. Director Juan Ramón Quintás Seoane stated that in the takeover bid launched by Gas Natural for ENDESA, since both entities were investees of savings banks, the possibility existed that the Banks involved may be interested in mediating between them while he was the Chairman of the Spanish Confederation of Savings Banks (CECA). In light of this possibility, he suspended his attendance at the meetings of the Board of Directors of ENDESA, S.A. once he had knowledge of such.

C.5. Give details of the mechanisms in place for detecting, identifying and resolving any potential conflicts of interest between the Company and/or its Group and its Directors, executives or significant Shareholders: In conformity with Article 41 of the Corporate Bylaws, “Notwithstanding the legal provisions on the matter, the Regulations of the Board of Directors will set out the duties of diligence, fidelity, loyalty and secrecy of the Directors, and in particular, their obligation of non-competition, the use of non-public information and on corporate assets, benefiting of business opportunities, conflicts of interest and related parties' transactions.” Thus the Board Regulations regulate: Directors’ incompatibilities in Article 23; Directors’ duties in Article 27; the duty of confidentiality in Article 28; the use of information and corporate assets in Article 29; and business opportunities in Article 30. The final provision of the Regulations provides that “The status of Director implies acceptance in writing of these Regulations and the declaration that the Director is not subject to any of the incompatibilities established in these Regulations. The Directors will sign, and will renew each year, a declaration of activities and assets related to the Company for the purposes of complying with the rules on incompatibilities.” In this connection, the Directors declare that they are familiar with the Corporate Bylaws, the Board Regulations and the Internal Regulations on Conduct in Securities Markets, and that they are not subject to any legal incompatibilities that could affect the discharge of the office of Director, and they sign a declaration of assets and activities disclosing, among other aspects, the following information: The offices they hold or duties they discharge at competing enterprises. Their membership of other Boards of Directors. Offices or duties at other companies that could potentially conflict with the Company’s interests. Securities in the Company and other Group companies. Interests/securities in other companies engaging in an activity of a type identical, analogous or complementary to the activity constituting the Company’s corporate purpose. Any other information of interest for the purpose of applying the rules on incompatibilities. Lastly, they accept the obligation to disclose transactions by family members and by companies related by way of equity interests to the declarant, where such transactions are material to the Company, and to notify any change in declared information. Furthermore, the Company has a set of Internal Regulations on Conduct in Securities Markets, which were approved by the Board of Directors on May 27, 2003, and which contain a commitment to ensure that they are kept up to date and that their provisions are known, and understood and accepted by all members of the organisation to whom they are applicable. Article 5 of the Regulations establishes the general rules of conduct in connection with securities. Persons subject to the rules, companies controlled by them and related persons must give written notice to the Company’s General Secretary of any transaction in the securities of the Company or of its investees. In addition, persons subject to the rules must also inform the General Secretary of any potential conflicts of interest. The General Secretary keeps a list, updated annually, of the persons subject to the Regulations and a record of notices, the

details of which are confidential and can only be disclosed to the Board of Directors or to whomever the Board designates in the course of a specific procedure. Lastly, the Company has Rules on Corporate Integrity, which consist of the Charter Governing Senior Management, the Charter Governing Executives and the Employees’ Code of Conduct, and which develop the principles and values of the Company, lay down the rules governing dealings with customers and suppliers, and establish the principles that should be followed by employees in their work: ethical conduct, professionalism and confidentiality. They also establish the limitations and define the incompatibilities arising from their status as executives and senior executives. D. RISK CONTROL SYSTEMS D.1. General description of the risk policy of the Company and/or its Group, giving details of and evaluating the risks covered by the system, together with evidence that the system is appropriate for the profile of each type of risk: The main principles defined by the Endesa Group when establishing its policy for the management of the principal risks are as follows: Comply with principles of good corporate governance Comply strictly with all Endesa’s rules. Each business and corporate area defines: The markets and product lines in which it can operate on the basis of having sufficient know-how and capabilities to ensure effective risk management. Criteria concerning counterparties. The authorised operators. The businesses and corporate areas establish for each market in which they operate the level of risk that they are prepared to assume on a basis that is consistent with the strategy defined. The limits of the businesses and corporate areas are approved by their respective Risk Committees or, should they not have one, by the Endesa Risk Committee. All the businesses and corporate areas must conduct their business within the limits approved in each case. The businesses, corporate areas, lines of business and companies establish the risk management controls required to ensure that the transactions are performed in the markets in accordance with the policies, principles and procedures of Endesa. Endesa's businesses expose it to a series of risks, grouped as follows: Business risk: risk inherent to each specific industry (e.g. uncertainty regarding demand and rainfall), including regulatory risk (uncertainty regarding changes in legislation). Market risk: risk of financial profit or loss caused by exposure to fluctuations in market prices. The main risks are: commodity risk, or risk that commodity prices (e.g. fuel, electricity, emission rights) will change interest rate risk or risk that interest rates will change. foreign currency risk, or risk that foreign exchange rates will change. Credit risk: the risk of loss due to a debtor’s non-payment, or more generally, risk related to uncertainties surrounding a debtor’s ability or willingness to meet its obligations (contractual disputes and arbitrage are

normally considered operational risk). Operational risk: risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. Endesa’s Risk Control System, in which global risk is defined as the risk resulting from the consolidation of all the risks to which ENDESA is exposed (market, credit, operating, and business risks) having regard to the effects of mitigating the various exposures to and categories of risk, makes it possible to consolidate and evaluate the risk exposures of all the business units and areas of the Company, as well as prepare the relevant management information for making decisions on risk and the adequate use of capital. The risk control process is the result of a model based, on the one hand, on the ongoing analysis of the risk profile, on the best practices prevailing in the energy industry or as benchmarks in risk management, on uniform measurement standards, on the separation between risk managers and controllers, and on the other hand, on ensuring the connection between the risk borne and the resources necessary to operate the businesses and on optimising the risk/return ratio of the businesses. The risk control and management cycle is the set of activities related to the identification, measurement, control and management of the different risks incurred by the businesses and corporate areas aimed at providing adequate risk control and management. Identification. The objective of risk identification of the Endesa Group is to maintain a prioritised and up-to-date repository of all risks borne by the corporation for coordinated and efficient involvement at all levels of the Company. This process entails the following tasks: Ongoing detection of new significant risks/opportunities assumed by the Corporation. Inclusion and regular update of the characteristics/descriptions of the risks detected. Preliminary quantification of the risks identified. Prioritisation of risks based on a defined set of classification criteria by relative importance. Addition of the data obtained to the Endesa Group risk map included in the corporate reporting scheme. Measurement. The objective of risk management at the Endesa Group is to obtain a global rating of risk exposure by the Corporation, including all the Group’s positions. Depending on the scope of the decision-making, the following parameters will be used: Economic Capital, Value at Risk, EBITDA at Risk, Margin at risk. To achieve this objective, the following steps are taken. Obtain timely, unique, consistent and reliable data on positions and risk factors. Model positions and risk factors consistently. Obtain parameters that encompass all the risks of the Endesa Group. Obtain supplementary parameters to understand the structure of the risk borne by the Endesa Group. Include data obtained from the measurement process in the corporate risk reporting scheme. Control. The aim of risk control is to guarantee the appropriate level of risk is borne by Endesa as a whole and by each business and corporate area individually. To achieve this objective, the following steps are taken.

Define quantitative benchmarks (limits) that reflect Endesa’s strategy and the risk tolerance established by Senior Management. Monitor the established limits. Identify and consider potential breaches of established limits. Establish the actions, procedures and information flows required to allow for the temporary revision of the limit structure to leverage specific opportunities that arise in each business. Management. The objective of risk management is to carry out the actions aimed at matching the levels of risk assumed at each level in the Company to the establish level of risk tolerance. Risk management is conducted throughout the Company, with each business and/or corporate area in charge of its scope of responsibility: tolerate (retain), address (mitigate), terminate (eliminate), transfer (take out insurance). D.2. Indicate the control systems in place for evaluating, mitigating or reducing the main risks of the Company and its Group. Interest rate risk: Interest rate fluctuations change the fair value of assets and liabilities that bear a fixed interest rate and the future flows from assets and liabilities bearing interest at a floating rate. The objective of interest rate risk management is to achieve a balanced debt structure that makes it possible to minimize the cost of the debt over several years with reduced income statement volatility. Based on ENDESA’s estimates and debt structure targets, hedging transactions are carried out by arranging derivatives that mitigate these risks. Foreign currency risk: The foreign currency risk relates mainly to the following transactions: Debt denominated in foreign currencies arranged by the Group companies and associates. Payments to be made in international markets in order to purchase fuel stocks. Income and expenses at Latin America subsidiaries in their functional currency and, in some cases, tied to the performance of the US dollar. In addition, the new assets relating to net investments in foreign operations whose functional currency is not the euro are exposed to foreign exchange risk in the translation of the financial statements of these foreign operations on consolidation. In order to mitigate the foreign exchange risk, the Endesa Group has arranged currency swaps and interest rate hedges. The Group also attempts to achieve a balance between the cash collections and payments relating to its assets and liabilities denominated in foreign currencies. However, the risk management strategies can be fully efficient with respect to limiting exposure to variability of interest and foreign currency exchange rates, which could have an adverse impact on its financial position and results. Commodity price risk: The Endesa Group is exposed to the risk of fluctuations in commodity prices, largely through:

Purchases of fuel stocks in the electricity generation process. Power purchase and sale transactions made in domestic and international markets. Exposure to this risk is managed at long term through the diversification of contracts, management of the procurements portfolio by tying it to indexes that perform in a similar or comparable way to end electricity prices (generation) or selling prices (retailing), and through contractual periodic renegotiation clauses, the aim of which is to maintain the economic equilibrium of procurements. At short and medium term fluctuations in the prices of procurements are managed through specific hedging transactions, generally using derivatives. Liquidity risk: The Group’s liquidity policy consists of the arrangement of committed credit facilities and current financial assets for an amount sufficient to cater for the projected needs for a given period based on the status and expectations of the debt and capital markets. Credit risk: The Group is not exposed to significant credit risk, since the average period for collection from customers is very short, a significant portion of loans are granted to employees and related parties, and cash placements made and derivatives arranged are with highly solvent entities. Endesa has a series of additional precautionary measures, which include: Analysis of the risk of each debtor where there is no external rating by agencies Request of guarantees as required. Operational risk: To minimise the economic impact of operational failures, the Group has an asset maintenance programme (above all for its power generation and distribution assets), rounded off with an insurance plan based on best market practices. D.3. If any of the risks affecting the Company and/or its group have materialised, indicate the circumstances that caused them and whether the control systems in place worked: In carrying out their business, ENDESA and its subsidiaries monitor the risks described in D.1. based on a corporate limit set in terms of economic capital. Endesa’s Risk Control System has been working adequately to control and manage its risks. D.4. Indicate whether any committee or other governing body is responsible for establishing and overseeing these control mechanisms and give details of its functions: Endesa’s global risk policy establishes various levels of delegated authority and governing bodies (committees and commissions) are set up so that decisions are taken collectively, thereby avoiding the risks associated with decisions made

individually. The main governing bodies with risk control responsibilities are as follows: 1. Audit and Compliance Committee 2. Endesa Risk Committee 3. Endesa Risk Commission 4. Business Risk Committee 5. Financial Committee 1. AUDIT AND COMPLIANCE COMMITTEE The Board of Directors is entrusted with the function of approving and overseeing the Audit and Compliance Committee’s system for evaluating and controlling risks material to Endesa and its subsidiaries. 2. ENDESA RISK COMMITTEE The Endesa Risk Committee (ERC) reports to the Audit and Compliance Committee. Regular meetings are monthly and special meetings are held whenever called by its Chairman. Its main functions are: To establish and keep updated Endesa’s Risk Policy, tailoring it to Endesa’s various businesses and corporate areas. To approve the risk policies of each business and corporate area. To approve the global risk measurement methods of the Endesa Group. To established global risk limits by business and corporate area. To resolve conflicts arising in any risk-related issue. To review periodically Endesa's level of risk exposure. To analyse the level of risk exposure of Endesa, its businesses and corporate areas. To authorise transactions which, because of their large impact on the level of risk, exceed the limits established by the Risk Committee, passing them over, where appropriate, to the Executive Management Committee of Endesa. To give remedial instructions in the event of non-compliance with any issue covered in the Risk Policy or Endesa’s internal regulations.

Monitor breaches of risk limits and the corrective measures decided by the ERC. Regular Committee meetings are held every two months and special meetings whenever called by its Chairman. 4. BUSINESS RISK COMMITTEE There are also Risk Committees in the businesses (Spain and Portugal; Europe; Latin America), which meet periodically to implement and oversee their risk policies, adapting them to the various businesses and companies, and to review the risk exposure of their business. 5. FINANCIAL COMMITTEE The Financial Committee meets periodically to approve the interest and foreign exchange risk management policies. D.5. Identification and description of the procedures for compliance with the various regulations affecting the Company and/or its group: The Company and its subsidiaries conduct business within the framework of various sets of industry-specific, securities-market, environmental, labour, tax and other regulations in Spain and in other countries where they operate. Rules, procedures and controls have therefore been established to prevent noncompliance or to promptly rectify any. Each of the Company’s business or corporate areas is responsible for complying with the regulations applicable to the industry in which it conducts business. However, there are four units with clearly defined responsibilities that ensure compliance with the internal and external regulations affecting Endesa and its subsidiaries: Office of the General Secretary and Secretary of the Board of Directors, which ensures that the activities of the Company’s governing bodies are lawful from the formal and substantive standpoints, ensures that they are compliant with the Corporate Bylaws and with the provisions made by regulatory bodies, and that the principles and rules of good governance are respected. Corporate Legal Advisory Department, which is responsible for promoting measures that ensure compliance by Endesa and its Group companies with the regulations in force in all applicable respects. To achieve this, internal procedures ensure that the Department participates in all areas of the business where there may be significant legal consequences. The Company also seeks the necessary advice on the regulations affecting it both in Spain and in the other countries in which it has a presence.

Corporate Audit Department, the brief of which is to ensure compliance with internal regulations directly applicable at Endesa’s wholly-owned investees. At Endesa’s other investees, its representatives on the governing and managing bodies encourage the option of these internal rules. The Department is also responsible for coordinating and overseeing the work performed by the external audit firms engaged. Corporate Finance and Control Department, which oversees and coordinates the financing of the business areas and subsidiaries. Insofar as risk control is concerned, it identifies, evaluates and controls risks, and measures whether the businesses and corporate areas are within the set limits. E SHAREHOLDERS’ MEETING E.1. List the quorums for convening the Shareholders’ Meeting, as per the Bylaws. Describe how they differ from the system of minimum quorums established in the Corporations Law: The quorums for convening the Shareholders’ Meeting are established in Article 25 of the Corporate Bylaws: “The Shareholders’ Meeting will be validly convened on first call if the Shareholders present in person or by proxy hold at least 25 percent of the subscribed voting capital stock. On second call, the Meeting will be validly convened regardless of the capital stock in attendance”, and in Article 26, relating to special resolutions: “An Annual or Special Shareholders’ meeting may resolve validly on debenture issues, capital increases or reductions, changes in the legal form, or the merger or spin-off, of the Company and, in general, any amendment to the Corporate Bylaws provided that on first call the Meeting is attended by Shareholders, in person or by proxy, holding at least 50 percent of the subscribed voting capital stock. On second call, the attendance of 25 percent of that capital stock will suffice.” There is no difference between these provisions and the minimum quorums provided for in Articles 102 and 103 of the Corporations Law. E.2. Explain the rules on adopting corporate resolutions. Describe how they differ from the rules established in the Corporations Law: In conformity with Article 31 of the Corporate Bylaws: “Resolutions must be adopted with the affirmative vote of the majority of the voting capital attending the Meeting in person or by proxy, without prejudice to the qualified quorums for convening and voting provided for by Law and in these Bylaws. For the adoption of resolutions the system for determining votes provided for in the Shareholders’ Meeting Regulations will be followed,” and in the case of special resolutions, Article 26 provides that “Where Shareholders holding less than 50 percent of the voting capital stock attend the Meeting, the resolutions referred to in the preceding Subarticle may only be adopted validly by the affirmative vote of two-thirds of the capital stock attending the Meeting in person or by proxy.” These provisions are similar to the rules established in the Corporations Law. E.3. List any rights of the Shareholders in connection with Shareholders’ Meetings that differ from those established in the Corporations Law: Neither the Corporate Bylaws, nor the Shareholders’ Meeting Regulations confer any rights on the Company’s Shareholders different to those established in the Corporations Law and regardless of whether the shares are common, non-voting, redeemable or preferred stock.

E.4. Indicate, as appropriate, the measures adopted to encourage participation by Shareholders at Shareholders’ Meetings: In compliance with the Corporate Bylaws, the Company approved the Shareholders’ Meeting Regulations with a view to bolstering Shareholder participation at Shareholders’ Meetings by suitably arranging for mechanisms to provide them with information and encouraging them to contribute to the decisionmaking process at the Company by exercising their rights to participate in debates and to vote. Where possible, ENDESA operates an active policy aimed at achieving the widest dissemination of call notices for Shareholders’ Meetings, while seeking to encourage Shareholder participation through the following measures: Widest dissemination of call notices for Shareholders’ Meetings by publishing them in the Official Mercantile Gazette (BORME) and various national, regional or local newspapers, and the maximum amount of time between the date of publication of the call notice and the date of holding of the Shareholders’ Meeting. This period 32 days in 2006, 35 days in 2005 and 33 days in 2004, so shareholders had ample time to familiarise themselves with the full wording of the resolutions and other supplementary information. Increase in the number of usual communication channels between Shareholders and the Company by making available to them an additional mailbox on the website under the “Shareholders’ Meeting” section. Signing of agreements with financial institutions to encourage Shareholder participation at Shareholders’ Meetings through financial incentives agreed on with those institutions and based on the quorum achieved, regardless of whether the vote is for or against the resolution in question.

By withdrawal of the Company from the contract: severance equal to three times the annual compensation. By a decision of the Company, based on the wilful misconduct or gross negligence of the executive in the discharge of his/her duties: no right to severance.

Post-contractual non-competition covenant: Two-year period. As consideration for the covenant, the executive is entitled to collect an amount equal to his/her fixed annual compensation. In line with market practices, a month and a half of compensation is guaranteed per year of service in the case of the three Senior Executives mentioned in the event of their departure from the company under specific circumstances.

APPENDIX III REPORT ON THE COMPENSATION OF THE BOARD OF DIRECTORS AND SENIOR MANAGEMENT 2006. APPOINTMENTS AND COMPENSATION COMMITTEE Translation of a report originally issued in Spanish. In the event of a discrepancy, the Spanish-language version prevails.

On 22 May 2006, the Spanish National Securities Market Commission approved the Unified Code of Good Governance which includes the principles of the European Commission’s Recommendation of 14 December 2004 and which is based on, among other items, the full transparency of the compensation received by the members of the Board, including the total compensation received by executive Directors. Furthermore, ENDESA internal regulations establish under Article 15, Section 6, and Article 33, Section 7, of the Board of Directors Regulations of ENDESA, S.A., that the Appointments and Compensation Committee shall disclose the compensation of the Board in “an annual report on the policy regarding Directors’ compensation and details of the compensation received by each of them as such, with a breakdown of all the items of which it is comprised. Without prejudice to being able to provide a full itemisation at a later stage, the compensation of Directors who are related professionally and permanently to the Company will be indicated globally for all of them, indicating the number of Directors receiving it by salary item.” As such, in accordance with current legislation and with the aim of complying with best Corporate Governance practice, the mandate described in the paragraph above was fulfilled with the Annual Report on the Compensation Policy of the Board of Directors and Senior Management, in which the principle of transparency of the Unified Code of Good Governance has been adopted for the presentation of remuneration in 2006: “all remuneration components and concepts must be fully transparent, including compensation agreed in the case of vacation of office.” BOARD OF DIRECTORS COMPENSATION Article 40. Compensation as specified in the Corporate Bylaws establishes that “The remuneration of the Directors will comprise the following items: a fixed monthly salary and a participation in profits. The overall annual salary for the entire Board and for the foregoing items will be one thousandth of the profits of the consolidated group, approved by the Shareholders’ Meeting. Notwithstanding, the Board of Directors may reduce this percentage for the fiscal years as it sees fit. All without prejudice of what is set forth in the third paragraph of this section in relation to expenses for attendance. It will be for the Board of Directors to set the distribution of the mentioned amount among the previous items and among the Directors when, as and how it freely determines. The members of the Board of Directors will also receive fees for attending each meeting of the managing bodies of the Company and its Committees The amount of these fees will be, at maximum, the amount that, in conformity with the previous paragraphs, is determined as fixed monthly salary. The Board of Directors may establish, within this limit, the amount of fees paid for attendance. The remuneration laid down in the preceding paragraphs, stemming from the membership to the Board of Directors, will be compatible with the other professional or employment compensation to which Directors are entitled for any other executive or advisory functions that they may perform for the Company different from those of supervision and collegiate decision characteristic of their condition as Directors, which will be subject to the legal applicable requirements. In compliance with the provisions of section 130 of the Spanish Corporations Law, Directors may only receive remuneration as a share of profits after the requirements of the legal and statutory reserve have been met and after the shareholders have been paid a minimum dividend of 4%.” Therefore, the members of the Board of Directors of ENDESA S.A. received compensation in their capacity as Directors of the Company, and, in some cases, on account of their membership of the boards of directors of subsidiaries, and members of the Board of Directors who exercise executive functions have also received compensation for this concept.

SAFEGUARD CLAUSES: BOARD OF DIRECTORS AND SENIOR MANAGEMENT Safeguard clauses in the event of dismissal or a change in control This type of clause is the same as the clause in the contracts of the Executive Directors and of the Senior Executives of the Company and of its Group. Such clauses are common practice in the market (*), according to the reports requested by the Company, and have been approved by the Board of Directors following a report from the Appointments and Compensation Committee. The clauses set forth the cases in which severance will be paid for termination of employment and contain a post-contractual non-competition covenant. The clauses establish the following: Termination By mutual agreement: severance equal to three times the annual compensation. By a unilateral decision of the executive: no right to severance, unless his/her withdrawal from the contract was based on a gross culpable breach by the Company of its obligations, where the post was rendered devoid of substance, where there was a change in control or other provisions for cases in which severance will be paid for termination of employment as described in Royal Decree 1382/1985. By withdrawal of the Company from the contract: severance equal to three times the annual compensation. By a decision of the Company, based on wilful misconduct or gross negligence on the part of the executive in the discharge of his/her duties: no right to severance. These cases differ from those arising from changes in the pre-existing labour relationship or in the termination of this relationship due to the early retirement of the Chief Executive Officer and Senior Executives. Post-contractual non-competition covenant Two-year period. As consideration for the covenant, the executive is entitled to collect an amount equal to his/her fixed annual compensation. At 31 December 2006, the number of beneficiaries, Executive Directors and Senior Executives totalled 33. Corporate Governance Report 127 endesa06 (*) In line with market practices, a month and a half of compensation is guaranteed per year of service in the case of the three Senior Executives mentioned in the event of their departure from the company under specific circumstances.
