Before detailing the main events of our administration, I would like to mention a series of occurrences that impacted our business and that were related to external events. I am referring to the effects caused by the earthquake in Chile, the drought experienced by the Colombian and Chilean market, and the unusual weather conditions in Brazil and Argentina, situations that tested our subsidiaries’ and their employees capacity With satisfaction, and despite the ravages of nature, I can say that thanks to Enersis´ diversified portfolio of assets, in the entire chain of the electricity business and in the main countries of the region, we were able to successfully overcome each and every complicated situation, maintaining our leadership position in an increasingly competitive energy market. Context 2010 The morning of February 27, 2010, nearly 70% of the population in Chile was affected by a tragic earthquake and then a tsunami, impacting the life of more than two million Chileans. The earthquake of intensity 8.8 on the Richter scale, the second largest in the history of our country, ravaged the electrical network and contracted economic activity for several months. To give you an idea of the magnitude of the earthquake, our subsidiary Chilectra reinstalled 144,244 meters of cable, 14,552 fuses and more than 1,000 crossarm. The above implied doing jobs, that could normally take up to two years and a half, in twelve days. In generation, our subsidiary Endesa Chile played a fundamental role in recovering normality and assuring the supply of electricity in the south central area of the country within hours of the occurrence of the catastrophe. Of the 5,611 MW of installed capacity that we own in Chile, more than 50% is located in the regions most affected by the earthquake; I refer to the Maule and the Bio Bio regions, and of those plants, only Bocamina, a 128 MW coal unit, suffered damages. This power plant, located in Coronel county, restarted operations on the thirteenth of December We had not yet recuperated from the earthquake and the tsunami when during the first days of April a storm hit the state of Rio de Janeiro, where our distribution subsidiary Ampla is located, leaving nearly 15,000 victims.

This forced our generation companies to incur in higher costs of energy purchases, greater transportation expenses and an increased use of fuel for thermal generation, compensating for the reduced hydrology availability. During the last days of December, 2010, our subsidiary Edesur, distribution company that supplies electricity in the southern area of Buenos Aires, Argentina, was faced with an unusual heat wave, the worst in the last 58 years, which led electricity demand to reach historical peaks, event that proved the capability of our entire infrastructure and lines in the area. Demand and growth As I mentioned, a series of events occurred during 2010, that, somehow, impacted our operations , although the last months of the year confirmed a trend that we began to visualize earlier in the year, and that is related to the recovery of the economic activity in the region, and specially, in the five countries in which we operate. To give you an idea of magnitude, the improved economic conditions during the last quarter of the year ratified the recovery of electricity demand in Chile, showing a 4.4% increase in electricity consumption , and also the consolidation in Peru and Brazil, with a 8.5% and 7.1% increase respectively. Electricity demand in the areas in which we operate increased an average 5.6% compared to 2009, as a result of the dynamic activity of the economies in these countries. This activity is confirmed by the positive perspectives for 2011, where, according to market consensus, forecast of growth rates are 6.3% for Peru, 6% for Chile, 5.2% for Argentina, 4.6% for Colombia and 4.5% for Brazil. Financial results Dear shareholders, the fact that we have a diversified portfolio of assets, both by business and by country, has allowed us to face the different situations described above in a positive manner and capture the improved macroeconomic conditions present during the last two quarters of the year. By this means, the efficient portfolio in the electricity generation, transmission and distribution business and the presence in Argentina, Brazil, Chile, Colombia and Peru allowed the company to reach Ch$2,261.691 million EBITDA, roughly US$4,433 million, during the year. This figure represents a 10% average annual growth rate for the 2006-2010 five year period, confirming the stategy and policies that the Enersis Group has adopted in the last few years. In line with the above, the Company contributed with Ch$486,227 million profit to controlling owners as of December 31, 2010. Although this figure represented a 26.4% reduction with respect to 2009, year in which the company reached historical profits, we must point out that during the last five years, profits have reached an average 34.8% increase. We have been capable of maintaining a balance among the contribution by business segment: distribution representing 43%, and generation and transmission the remaining 57%. In terms of country, Chile contributes with 32.1% of consolidated EBITDA, Brazil with 30.1%, Colombia with 25.4%, Peru with 8.7% and Argentina with 3.8%.

Total Operating Income of the period totaled Ch$ 1,704,301 million, equivalent to an 11.6% decrease, mainly due to lower results of our generation business segment, fundamentally in Chile and Brazil, partially compensated by the better performance of our distribution business in Peru and Colombia. Physical sales in generation reached a total 63,431 GWh, and in distribution climbed from 63,694 GWh to 67,274 GWh, which represents a 5.6% increase. Our main business During 2010 we carried out two operations intended to focus our actions on our “core” or essence, which is the electricity business, and thus to concentrate on the challenge to meet the increased requirements of energy supply demanded by more than 50 million people we service in Latin America. Within that framework, we accept the bid submitted by the company Graña y Montero SAA, to acquire the entire holding in the Compañía Americana de Multiservicios Limitada, CAM, and equally, we accept the bid submitted by Riverwood Capital LP to purchase the entire holding in Synapsis Soluciones y Servicios IT Ltda. As noted above, such sales were intended to focus the operations of Enersis in its “core business” which is the electricity business and focus resources to meet planned investments in generation and power distribution business segments. Among the award criteria, consideration was placed on the applicant company´s capacity to guarantee the continuity of excellence in services of both Synapsis and CAM, and also the concern for their workers. Enersis group confirms its commitment to remain a model of the energy industry, both in the electricity supply necessary and sufficient to support growth in the five countries of operation, and the quality of service to its more than 13 million customers. Contribution to supply An example of this, and of the company´s commitment with each of the countries in which it operates, was the construction of the hydroelectric plant El Quimbo (400 MW) in Colombia, in Chile, the re-entry of the environmental impact assessment study (EIA) of Central Hidroeléctrica Neltume (490 MW) and the presentation of the EIA of its transmission line, and finally, the presentation of the EIA of Central Hidroeléctrica Los Cóndores transmission line, all in the generation business segment. In the distribution business, I would like to highlight, among other initiatives, a number of projects that aim to meet the increasing demand for electricity in the cities we serve, initiatives related to energy efficiency and reducing the levels of energy losses and also the development and implementation of the first charging points for electric cars through Electrolinera. In short, the company maintains an active portfolio of projects to meet the increased requirements of demand: In Chile, for example, as noted, are the hydroelectric plants Los Condoress (150 MW), Neltume (490 MW), Choshuenco (128 MW), HidroAysén (2,750 MW) and mini hydro Piruquina (7.6 MW), and thermoelectric Punta Alcalde (740 MW). Currently under construction, the thermoelectric Bocamina II (370 MW), will begin operations in late 2011. In the rest of Latin America, in Peru we may highlight the hydroelectric Central Hidroeléctrica Curibamba (188 MW), an initiative that is in the process of environmental assessment, and in Colombia, the construction of El Quimbo with 400 MW.

That is why, by 2014, we will increase our capacity to 15,600 MW, this, with the commissioning of Bocamina II and El Quimbo. After 2014, some of the projects that we keep under review will come into operation. Simultaneously, we have a large portfolio of projects under analysis or in different degrees of feasibility and basic design, totaling close to 13,000 MW. In other words, the Enersis Group has a broad portfolio of initiatives and we are willing to support the growth of the five countries in which we operate, through the implementation of projects that go hand in hand with environmental stewardship and supporting the development of the communities found in the surroundings. However, we note, especially in the Chilean market, some delay in the process of environmental approval of projects, delays that ultimately threaten the viability of the initiatives themselves. In 2010 we witnessed the paralization of a project and subsequent suspension, despite having received the corresponding environmental approval. Any investor and player in the energy industry needs clear and stable rules. The delay in the process of environmental approval must be solved as soon as possible; if not, Chile will not be able to have the 1.200 MW of additional capacity it requires each year to reach it´s 6% growth rate goal. We understand that when a project makes sense and it is in line with the country’s proposed energy strategy it must be processed in an agile manner, respecting all the criteria stipulated by environmental regulation. And in contrast, if a project does not meet the requirements, the investor is entitled to know promptly to avoid unnecessary costs on all involved, including the State itself. HidroAysén We can say with satisfaction that the HidroAysén project has advanced in its environmental assessment process, receiving in October 2010 the third ICSARA with a total of 199 questions, reducing doubts about the services involved by more than 85% compared to second ICSARA. At the same time, I can proudly point out that the administration of HidroAysén and companies that promote its development, have been able to focus the discussion on energy development in the country on issues of substance, while wielding opponent’s arguments have fallen due to their own inconsistency. For example, just to name a few, critics say that Patagonia will be destroyed and it is not a sustainable initiative. But being realistic, the area of the HidroAysén reservoir is equivalent to 0.05% of the total area of the Aysén region and represents 1.5% of its natural lakes. There are some groups with strong financial backing from foreign entities that ignore the real energy situation in the country and have been commissioned to confuse the public with publicity that does not conform to reality and focuses the debate on other issues. HidroAysén opponents argue that the 2,750 MW, which will flood 5,900 hectares, can be replaced with non-conventional renewable energies, but these groups do not tell the population that in order to replace HidroAysén, 90,000 to 100,000 hectares of wind farms would we required, from 160,000 to 180,000 hectares of solar panels, causing a much greater environmental impact. We must be clear that in order to grow 6%, Chile needs roughly 1,200 MW of additional capacity each year, and that growing at such rate it is estimated that we could become a developed nation by year 2020, with social equity and new challenges. But we must also be clear about the fact that Chile has virtually no fossil fuels and, Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 8 Enersis 2010 Annual Report therefore, not to depend on imported fuels that are less efficient and more polluting, we should make use of a natural, clean, renewable and indigenous resource like water. HidroAysén gives Chile energy independence and we want the public to understand that this is relevant to the country and its people. The investment decision will be taken with all required permissions approved, and we do see that the country´s will is to consider this initiative as a strategic project for development. Social Responsibility 2010 tested our commitment to each of the countries where we operate, and in particular with Chile. After the earthquake, our support to the country went further and was not only limited to “do our work well” to restore normal power supply as soon as possible. Enersis Group was the first company to donate to the National Fund for Reconstruction, contributing with the sum of US$10 million. Also, Fundación Endesa (Spain) created a special fund to help Chile, which has 1 million euros. These resources will be used to rebuild part of the infrastructure of schools and educational establishments damaged by the earthquake in the areas of influence of our companies. In 2010, the first decree to enforce part of the donation was issued, benefiting a total of 56 establishments throughout the country. The above, in line with our Sustainability Policy, where one of our main focuses is the support, promotion and development of activities related to education and its improvement. During the fourth quarter, our subsidiary Endesa Chile certified environmental management systems (EMS) to ISO 14,001 in thermoelectric plants Quintero (257 MW), Huasco TG (64 MW) and Diego de Almagro (24 MW), and therefore, at December 31, 2010, 100% of our installed capacity had its EMS certified by such standard. I am proud to say that the company presented this year it´s first sustainability report, a document that details our Sustainability Policy and that of the group in Chile. On the other hand, I would like to share with you the number of awards we received in 2010, awards that confirm our achievements and encourage us at the same time, to improve our policies and good practices every year. The awards include, among others, the second place of the Corporate Transparency Index 2010, being recognized as the fourth most profitable utility in the world, the eighth place in the ranking of the best companies for working mothers and fathers and the first place in the utilities category of the ranking of the top 100 best companies to invest in Chile.

Our commitment, that of our companies and the more than 12,250 employees who work in Latin America on behalf of the Enersis Group, is to develop solutions tailored to the needs of 13 million customers we have and contribute to the development of the five countries in which we operate, cooperating with the energy supply, maintaining the quality standards of service and our leadership position. As president of Enersis, and on behalf of its board, I want to congratulate each of the workers and employees of our companies, for their work in 2010 and demonstrated commitment in such difficult situations, such as the earthquake of February 27, time in which teams of our subsidiaries Edesur, Ampla, Coelce, Codensa and Edelnor traveled to Santiago, Chile to assist in the work of restoration of the electricity. As I said in the annual report 2009, we are a multinational energy company, we have a diversified portfolio of assets in five countries, we have established permanent presence, knowledge and skills, and a solid financial structure and liquidity. In short, we have the tools necessary to make the Enersis Group, head of Endesa’s business in Latin America managed from Chile, “a regional and global example”. We have been able to implement a successful strategy to increase our shareholders return every year, creating value, applying increasingly stringent standards for our actions and behavior, establishing goals on health and safety constantly greater; in short, we have been capable of leading the electricity industry not only as a consequence of our installed capacity, number of customers or market capitalization, but we are also leaders in the electricity sector in Argentina, Brazil, Chile, Colombia and Peru because of our performance, our excellent work and due to the strong commitment we have with society and with each of the 50 million people we serve in Latin America.

Historical background On June 19, 1981, Compañía Chilena de Electricidad S.A. formed a new corporate structure which gave birth to a parent company and three subsidiaries. One of these was Compañía Chilena Metropolitana de Distribucion Electrica S.A. In 1985, under the Chilean government’s privatization policy, the process of transferring the share capital of Compañía Chilena Metropolitana de Distribucion Electrica S.A. to the private sector was begun, ending finally on August 10, 1987. In this process, the pension fund management companies (AFPs), company employees, institutional investors and thousands of small shareholders joined the Company. Its organizational structure was based on activities or operative functions whose results were evaluated functionally and its profitability was limited by a tariff structure as a result of the Company’s exclusive dedication to the electricity distribution business. In 1987, the company’s board proposed forming a division for each of the parent company’s activities. Four subsidiaries were therefore created to be managed as business units each with its own objectives, thus expanding the company’s activities toward other non-regulated activities but linked to the main business. This division was approved by the extraordinary shareholders meeting of November 25, 1987 which defined its new corporate objects. Compañía Chilena Metropolitana de Distribucion Electrica S.A. thus became an investment holding company. On August 1, 1988, as resolved at the extraordinary shareholders meeting of April 12, 1988, one of the companies born from the division changed its name to Enersis S.A. At the extraordinary shareholders meeting of April 11, 2002, the company’s objects were modified, introducing telecommunications activities and the investment and management of companies whose businesses are in telecommunications and information technology, and internet trading businesses. In 1988, and in order to successfully meet its development and growth, the company was split into 5 business units which in turn gave birth to five subsidiaries. Of these, Chilectra and Río Maipo were responsible for electricity; Manso de Velasco Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 63 2010 Annual Report The company´s businesses concentrated on electrical engineering and construction services, plus real-estate management, Synapsis in the area of information technology and data processing, while Diprel focused on providing procurement and commercialization of electrical product services. Today, Enersis is one of the largest private electricity groups in Latin America in terms of consolidated assets and operating revenue, achieved through steady and balanced growth in its electricity businesses: generation, transmission and distribution.

Between November 2004 and December 2006, Enersis signed two committed and unsecured revolving lines of credit through its old branch in the Cayman Islands. In the same period, Endesa Chile, through its Cayman Islands branch, signed three committed revolving lines of credit without senior collateral. These credit agreements were structured with various banks for a total sum of US$ 550 million for Enersis and US$650 million for Endesa Chile, and have maturities falling between 2009 and 2011. Also, in June 2008, Endesa Chile signed a renewable unsecured syndicated credit agreement for US$200 million and a loan agreement for 6 years for US$200 million with the same banks. The latter facility was used to refinance part of the July 2008 maturities of the Yankee bonds for US$400 million. Finally, in October the same year, amendments were signed for the two lines of credit of Enersis and the three of Endesa Chile in order to significantly reduce the covenants in those agreements. The principal changes included: an increase in the level of materiality of cross defaults to US$50 million coupled with a requirement of a payment in penalty for that same amount; a reduction in the number of financial covenants; a more comfortable leverage covenant for Endesa Chile; a modification of the documentation to reflect the adoption of IFRS, and other changes in definitions and conditions that provide greater flexibility for both companies.

Hedging policy 2.4.1. Exchange rate The Group’s exchange rate hedging policy is based on cash flows and its objective is to keep a balance between flows indexed to foreign currency (dollar) and the levels of assets and liabilities in that currency. During 2010, Enersis’s financial transactions enabled it to maintain a level of dollar liabilities adjusted to the expected flows in that currency. As part of the policy, Endesa Chile contracted swaps for US$400 million to cover the exchange risk of a local bond issued in Unidades de Fomento (UF) and that were exchanged into dollars which is the currency in which the subsidiary’s revenues are denominated. It also contracted forwards for US$85 million to cover the exchange rate risk of future payments related to the construction of Bocamina II power plant, that were denominated in UF exchanging them into dollars which is the currency in which the subsidiary’s revenues are denominated. Additionally, in Chile, forwards were purchased for US$389 million to cover the different currency flows coming from different countries in Latinoamerica. The rest of the companies in the Group in the region contracted US$ 38 million worth of forwards and swaps in order to denominate debt according to the indexation of their inflows and outflows. 2.4.2. Interest rate The Group’s policy consists of maintaining hedge levels, total fixed-rate debt and/or hedge over total net debt, within a band of more or less 10% with respect to the hedging level established in the annual budget. During 2010, interest rate swaps were therefore contracted for US$30 million to fix libor (London Interbank Offering Rate). At year-end 2010, the consolidated fixed rate debt plus hedged debt to net debt was 51.4%. 3. Credit rating On November 9, 1994, Standard and Poor’s and Duff & Phelps rated Enersis for the first time as BBB+, i.e. an investment grade company. Later, in 1996, Moody’s rated the company’s foreign currency long-term debt as Baa1. Over time, most of the credit ratings have varied. All are now investment grade with stable outlook, based on the diversified asset portfolio, the liquidity and suitable debt service policies. The credit profile of Enersis has continued to strengthen in 2010, with progress in the liquidity position and reductions in leverage. The positive financial and operational profile perspective of Enersis has been reflected in an improvement in January 2010 by Fitch Ratings in our corporate rating for foreign and local currency debt, as well as for the Yankee bonds, from BBB to BBB+. There was a similar improvement in the domestic rating from AA- to AA. Along the same line, the rating agency Standard and Poor’s raised the corporate and senior debt credit rating of Enersis in February 2010 to BBB+ from BBB, with stable outlook.

Risk factors The Group’s activities are subject to a broad range of governmental standards and any modification of such standards could affect the Group’s activities, economic situation and operating results. The operating subsidiaries of the Group are subject to a wide range of rules on tariffs and other regulations governing their activities, both in Chile and in other countries where they operate. Therefore, the introduction of new laws or regulations, including amendments to laws or rules may impact their activities, financial situation and results of operations. These new laws or regulations, in occasions, change aspects of regulation that may affect existing rights, which could cause an adverse effect on future accounts of the Company. The activities of the Group to are subject to extensive environmental regulations that Enersis complies with on a permanent basis. Any changes made in these areas could affect the activities, financial condition and results of operations. Enersis and its operating subsidiaries are subject to environmental regulations which, among other things, require the company to conduct environmental impact studies for future projects, obtaining permits, licenses and other authorizations and the fulfillment of all requirements of those licenses, permits and norms. As any other regulated company, Enersis cannot guarantee: • • The approval from regulators of environmental impact studies. That public opposition may not cause delays or modifications to any proposed project and That laws or regulations may not change or be interpreted in a manner that could increase the costs of compliance or that affect the operations, plants or the plans for companies in which the Group has been involved in. • Group’s commercial activity has been planned so as to mitigate any impacts of changes in hydrological conditions. The Company’s operations include hydroelectric generation, and therefore, the company depends on hydrological conditions that exist at each moment in the large geographical areas where its hydroelectric generation facilities are located. If hydrological conditions lead to a drought or other conditions that adversely affect hydro generation activity, the results could be adversely affected, and for this reason, Enersis has defined, as an essential part of its commercial policy, not to contract 100% of its capacity. The electricity business is also affected by atmospheric conditions such as average temperatures which determine consumption. Weather conditions can make a difference in the margin obtained by the business.

Credit risk Given the current economic situation, the group has been conducting detailed monitoring of credit risk. 1.1.1. Commercial accounts receivables Credit risk in accounts receivable, corresponding to the accounts receivable originating from commercial activities, has been historically very limited given that the short term collection conditions with customers doesn’t allow them to individually accumulate significant amounts. This applies to both, our electricity generation and distribution business. Within our electricity generating business line, in the event of non-payment, some countries allow power supply cut-offs, and in almost all contracts a lack of payment is established as cause for contract termination. For this purpose, credit risks are constantly monitored and the maximum amounts exposed to payment risks are measured, and as mentioned, are limited. For our electricity distribution business line, the energy supply cut-off is a power held by our companies in case of default by our customers, and is applied in accordance with the applicable regulation in each country, making the credit risk evaluation and control process easier, which is also limited. 1.1.2. Financial assets Surplus cash flow investments are placed in prime domestic and foreign financial entities (with an investment grade equivalent risk rating) with limits set for each entity. In the selection of banks for investment, consideration is given to those that hold at least two “investment grade” ratings, according to the three main international rating agencies (Moody’s, S&P and Fitch). Positions are backed up by treasury bonds from the country of operations and/ or instruments issued by the most reputable banks, favoring, wherever possible, the number ones. Derivatives are engaged with highly solvent entities; and therefore about 90% of operations are conducted with entities that hold an A rating or higher.

Risk measurement The Enersis Group measures the Value at Risk (VaR) of its debt and financial derivatives positions in order to guarantee that the risk taken by the company remains consistent with the risk exposure defined, thus restricting the volatility of its income statement. The positions portfolio used in the calculations of the current Value at Risk is comprised of: • Debt, and • Financial derivatives. The calculated Value at Risk represents the possible value loss of the aforementioned positions portfolio over one day time horizon with 95% of confidence. The volatility of the risk variables that affect the value of the positions portfolio has been studied, including: • • The U.S. dollar Libor interest rate. For debt, taking into account the different currencies our companies operate under, the local indexes usual used in banking, and The exchange rates of the different currencies involved in the calculation. • The calculation of VaR is based on generating possible future scenarios (one day) of market values (both spot and term) for the risk variables, using the Monte Carlo methodology. The number of scenarios generated ensures compliance with the simulation convergence criteria. A matrix of volatilities and correlations between the various risk variables calculated based on the historical values of the logarithmic price return, has been applied to simulate the future price scenario. Once the price scenarios have been obtained, the fair value of the portfolio is calculated using such scenarios, obtaining a distribution of possible values at one day. The one-day value at risk, with 95% confidence, is calculated as the 5% percentile of the potential increases in the fair value of the portfolio in one day. The various debt positions and financial derivatives included in the calculation have been valued consistently using the financial capital calculation methodology. Taking into consideration the hypothesis described, the Value at Risk of the positions previously discussed by type of position is shown in the table below: Financial Positions Million Chilean Pesos Type of Interest Type of Exchange Rate Correlation Total 31st December, 2010 31st December, 2009 38,847,459 29,778,643 539,575 (2,695,024) 3,860,371 (7,740,115) 36,692,010 25,898,899 The positions of Value at Risk during 2010 and 2009 have evolved according to maturity/operation beginning during the period.

Other risk As is customary in bank loans and capital market operations, a portion of the indebtedness of Enersis and its subsidiary Endesa Chile, is subject to cross-default provisions. If certain defaults of relevant subsidiaries are not remedied, a cross default could affect Enersis and Endesa Chile and, and under this scenario, certain liabilities of these companies could be accelerated. Nonpayment, after any applicable grace period, of the debts of these companies, or their Relevant Subsidiaries, with an individual principal amount outstanding in excess of US$ 50 million, and with a past due amount also in excess of US$ 50 million, could lead to the acceleration of syndicated loans. Furthermore, these debt facilities also contain clauses which, in situations other than non-payment, in these companies or in one of their relevant subsidiaries, such as bankruptcy, insolvency, adverse judicial rulings for an amount in excess of US$ 50 million, expropriation of assets, among others, could cause declaring the acceleration of these debts. Similarly, nonpayment, after any given applicable grace period, of any debt of Enersis or its Chilean subsidiaries, with a principal in excess of US$ 30 million, could potentially give rise to the anticipated forced payment the Yankee bonds. There are no clauses in the credit agreements by which changes in the corporate or debt classification of these companies from risk classification agencies could trigger prepayments. Nevertheless, a modification in the Standard & Poor’s (S&P) debt risk classification in foreign currency could trigger a change in the margin applicable to determine the interest rate, in the syndicated loans executed in 2004 and 2006, and in local credit lines executed in 2009.

Argentina 1.1. Industry structure Law No. 15,336 of 1960 and Law No. 24,065 of 1992 (together, the Argentine Electricity Act) set the regulatory framework for the electricity sector. Under the Argentine Electricity Act, the Federal Government: • Divided the electricity industry into three business segments: generation, transmission and distribution, to enable the electric market development under conditions of free competition for generation with reduced tariffs, requirements regarding quality standards, and restrictions to ownership concentration; • • Created the Mercado Eléctrico Mayorista (Wholesale Electricity Market) or “MEM” where four categories of agents (generators, transmitters, distributors and large customers) are allowed to buy and sell electricity as well as related products; Imposed the Compañía Administradora del Mercado Mayorista Eléctrico (Administrative Company for the Wholesale Electricity Market) or “Cammesa,” responsible for the dispatch coordination, the administration of the agent’s transactions in the MEM and the calculation of the spot prices. The agents participate in Cammesa as shareholders through their corresponding associations with the Secretariat of Energy, the owner of the remaining 20% of the capital stock. The Ministry of Federal Planning, Public Investment and Services appoints the Cammesa chairman; and • Created the Ente Nacional Regulador de la Electricidad (Electricity National Regulatory Agency) or “ENRE,” in charge of regulating public service activities in the electricity sector and imposing jurisdictional decisions. The Ministry of Federal Planning, Public Investment and Services, through the Secretariat of Energy, is primarily responsible for the implementation of the Argentine Electricity Act. Among the main tasks, the Secretariat regulates the system dispatch and the activities in the MEM, and grants the concessions or authorization for each activity in the electricity sector. The generation sector is organized on a competitive basis, with independent generators selling their output on the MEM’s spot market or through private contracts to purchasers on the MEM’s contract market or to the CAMMESA by means of special transactions such as the contracts under resolutions SE N°220/2007 and N°724/2008. Transmission works under monopoly conditions by several companies to whom the Federal Government grants concessions. The international interconnected transmission systems also require concessions granted by the Secretariat of Energy. Transmission companies are authorized to charge different tolls for their services. Distribution is a public service that works under monopoly conditions and is provided by companies who have also been granted concessions. Distribution companies may obtain electricity either in the MEM’s spot market at a price called “seasonal price,” or in the MEM’s term market through private contracts with generators. The seasonal price, defined by the Secretariat of Energy, is the cap for the costs of electricity bought by distributors and passed through to regulated customers. Regulated customers are supplied by distributors at regulated tariffs, unless they have a minimum capacity demand of 30 kW, in which case they can choose to contract their supply directly from generators in the MEM´s spot market, becoming “large customers” who may freely negotiate their prices with generating companies.

All generators that are MEM agents have to be connected to the Sistema Argentino de Interconexión (NIS) and are obliged to comply with the dispatch order to generate and deliver energy to the Argentine NIS, in order to be sold in the spot market or in the term market. The spot price is calculated on an hourly basis by Cammesa and must reflect the cost of the marginal kW to be dispatched in the Argentine NIS and is paid to generators and sellers of energy at the spot market. The Argentine Electricity Act sets that electricity prices in the spot market are determined on a marginal cost basis. Since 2002, the Secretariat of Energy started to modify several criteria regarding the spot prices and imposed, among other restrictions, caps for the spot prices to be paid to the generators and only recognized for calculations purposes the natural gas costs established by the Federal Government, even though additional costs are collected by the market and paid to the generator. 1.2. Changes to the regulatory framework Law No. 25,561, the Public Emergency Law, was enacted in 2002 to manage the public crisis which began that year. It forced the renegotiation of public service contracts (such as electricity transmission and distribution concession contracts) and imposed the conversion of dollar denominated obligations into Argentine pesos at a pegged rate of Ar$ 1 per $ 1. It also empowered the Federal Government to implement additional monetary, financial and exchange measures to overcome the economic crisis in the medium term. These measures have been periodically extended. In fact, Law No. 26,563, enacted in December 2009, extended the measures until December 31, 2010. The Secretariat of Energy introduced several regulatory measures aimed to correct the effects of the devaluation into the MEM’s costs and prices and to reduce the price to be paid by the final customers. The mandatory conversion of transmission and distribution tariffs from dollars to Argentine pesos at the pegged rate of $ 1 per Ar$ 1, when the market exchange rate was approximately $ 1 per Ar$ 3 and the regulatory measures to cap and reduce the spot and seasonal prices hindered the pass through of generation variable costs into the tariffs to final customers. Resolution SE No. 240/2003 changed the way to fix spot prices, decoupling the spot price calculation from the marginal costs of operation. Until this resolution, spot prices on the MEM were typically fixed by units operating with natural gas during the warm season (from September through April) and units operating with fuel/diesel in the winter (May-August). Then, due to restrictions on natural gas supply, winter prices were higher, and related to imported fuels priced in dollars. Resolution SE No. 240/2003 seeks to avoid the pegged price indexation to the dollar and, although generation dispatch is still based on actual fuels used, the calculation of the spot price under the Resolution is defined as if all dispatched generation units did not have the existing restrictions on natural gas supply. Water value is not considered if its opportunity cost is higher than the cost of generating with natural gas. The resolution also set a cap on the spot price at 120 Ar$/MWh, which was still in place during 2010. The real variable costs of thermal units that used liquid fuel were paid by CAMMESA through a Temporary Dispatch Over cost, plus a US$2.5/MWh margin, according to Note SE 6,866 of 2006 and 6,169 of 2010, in place since May 2010 and until December 2011. In this scenario, CAMMESA sells power to distributors who pay seasonal prices and buy power from generators at spot prices that recognize the rising gas prices and at a contract price set under the instructions of the secretariat of energy.

This resolution sets a priority of payment for different services: capacity payment, fuel costs, energy sales margin, etc. CAMMESA accumulates debt with generators and the system gives an incorrect price signal to agents by failing to encourage electricity consumption savings and investments to meet growth in demand, including investments in transmission capacity. In order to enhance the energy supply the Secretariat of Energy created different schemes to sell more energy. Resolution 1,281/2006 created the Energy Plus Service, which is the offer of new electricity capacity to supply the growth in electricity demand, over the “Base Demand,” which was the demand for electricity in 2005. The Energy Plus Service is supplied by generators that install new capacity or that offer existing generation capacity not connected before to the NIS. All “large customers” that, as of November 1, 2006, had a higher demand than their Base Demand, had to contract excess demand with the Energy Plus Service. The consumption that exceeded the Base Demand without a contract to supply should pay additional amounts for the surplus energy. Resolutions SE No. 220/2007 and No. 724/2008 gives thermal generators the opportunity to reduce some of the adverse effects of Resolution SE No. 406/2003 by entering into MEM Supply Commitment Contract or “CCAM.” Generators can commit maintenance or repowering investments to improve their unit’s availability and add additional capacity to the system. After authorization, the generator can sign a CCAM at prices that permit the recovery of capital expenditures. Additionally, energy sales through a CCAM receive payment priority compared with spot energy sales (Res. No. 406/2003). Generators with a CCAM can supply energy to Cammesa for up to 36 months, renewable only for an additional period of six months. During 2009, Resolution SE No. 762 created the Hydroelectric National Program to promote the construction of new hydro plants. The program enables authorized generators to subscribe energy supply contracts with Cammesa for up to fifteen years, at prices that allow for an investment recovery. On November 25, 2010, the Secretariat of Energy signed an agreement with some generating companies, including subsidiaries of Enersis, with the purpose of (i) increasing the availability of thermoelectric units, increase prices and the capacity of electricity; and (ii) build new generation units by the contribution CAMMESA´s unpaid debt with generators. Through Resolution SE No. 712/2004 Foninvemem was created, a fund whose purpose is to increase electricity capacity/generation within the MEM. Pursuant to Resolution SE No. 406/2003, the Secretariat of Energy decided to pay the generators the spot prices up to the amount available at a stabilization fund, after collecting the funds from the purchasers in the spot market at seasonal prices, lower than spot prices for the same period. Pursuant to Resolution SE No. 1,193/2005 all private generators in the MEM were called to participate in the construction, operation and maintenance of the electric energy generation plants to be built with the Foninvemem, consisting of two combined cycle generation plants of 850 MW each. These power plants are powered by natural gas or alternative fuels, that were completed during 2010 as a combined cycle. These power plants are powered by natural gas or alternative fuels.

As of the date of this report, ENRE has not defined new tariffs, and maintains in force the transitional tariff regime. Resolution Nº45/2010 eliminated from March 2010 the payment of bonuses to the Energy Efficiency Program (PUREE) for those customers whose demand is less than 1,000 kwh every two month period, these were the only customers to receive these bonuses. The puree was established in 2004 and set bonuses and penalties to customers, depending on your level of energy savings; the net difference between the bonuses and penalties were originally deposited in the stabilization fund, but then was changed at the request of Edesur and Edenor, which were approved by the secretary of energy to use 100% of the funds to compensate for the variation of costs that were not transferred to the repositioning of the tariff (cost monitoring mechanism – MCC). In order to give priority to the internal market supply, the Secretariat of Energy adopted additional measures that restricted electricity and gas exports. Resolution SE No. 949/2004 established measures that allowed agents to export and import electricity under very restricted conditions. These measures prevented generators from satisfying their export commitments. These restrictions are expected to continue, especially considering that during 2010, Resolution Enargas Nº 1410, modifying procedures for the dispatch of gas from October 2010. In accordance with that resolution, the priority of gas release is as follows: i) Residential and Commercial Users; ii) Compressed Natural Gas - CNG, iii) Large Customers; iv) Thermal Units, v) Exports. 1.3. Others Electricity facilities are subject to federal and local environmental laws and regulations, including Law No. 24,051, or the Hazardous Waste Law, and its ancillary regulations. Certain reporting and monitoring obligations and emission standards are imposed on the electricity sector. Failure to satisfy these requirements entitles the government to impose penalties, such as suspension of operations, which, in case of public services, could result in the cancellation of concessions. 2. Brazil 2.1. Industry structure Brazil’s electricity industry is organized into one large interconnected electricity system, which is known as the Sistema Interligado Nacional (the Brazilian NIS), which comprises most of the regions of Brazil and several other small, isolated systems. Generation, transmission and distribution are legally separated activities in Brazil. According to the specifications set forth in Law No. 9,427/96 unregulated customers in Brazil are currently those customers: (i) who demand at least 3,000 kW and choose to contract the energy supply directly with generators or retailers; or (ii) who demand at least 500 kW (and less than 3,000 kW) and choose to contract the energy supply directly with alternative generators or traders. The electricity industry in Brazil is regulated by the Federal Government, acting through the Ministry of Mines and Energy, or MME, which has exclusive authority over the electricity sector, and whose primary role is to establish the policies, guidelines Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 90 Enersis 2010 Annual Report and regulations for the sector. Regulatory policies are implemented by the Brazilian governmental agency for electric energy (ANEEL), whose main responsibilities include, among others: (1) supervision of the concessions for electricity sale, generation, transmission and distribution activities, and approval of electricity tariffs; (2) enactment of regulations for the electricity sector; (3) implementation and regulation of the exploitation of electricity resources, including the use of hydroelectricity; (4) promotion of a bidding process for new concessions; (5) resolution of administrative disputes between electricity sector agents; and (6) setting the criteria and methodology for determining distribution and transmission tariffs. Other regulatory authorities include: (i) the Brazilian Electricity System Operator (ONS), comprised of generation, transmission and distribution companies, and independent consumers, responsible for the coordination and control of the generation and transmission operations of the Brazilian NIS; (ii) the Electricity Trading Board (CCEE), a company in which agents are gathered in four categories: Generation, Distribution, Trading and Consumers and whose main purpose is to carry out the wholesale transactions and trading of electric power within the Brazilian NIS; and (iii) the Brazilian Energy Policy Council (CNPE) in charge of developing the national electricity policy. The market regulation established pursuant to Laws No. 10,847 and 10,848 seeks to provide cheaper tariffs for consumers and guarantees the expansion of the system, with the Power Research Company, (EPE), a governmental body, responsible for the planning of generation and transmission activities. This market regulation has defined an unregulated contracting environment and a regulated environment. In the unregulated contracting environment, the conditions for purchasing energy are negotiable between suppliers and their customers. Regarding the regulated environment, where distribution companies operate, the purchase of energy must be conducted executed pursuant to a bidding process coordinated by ANEEL. Pursuant to the market regulation, 100% of the energy demand from distributors must be satisfied through long term contracts in advance of the expiration of current contracts in the regulated environment. Another change imposed on the electricity sector is the separation of the bidding process for “existing power” and “new power project.” The government believes that “new power project” needs more favorable contractual conditions as long term power purchase agreement (15 years for thermal and 30 years for hydro) and certain price level for each technology. These agreements promote investment for the required expansion. On the other hand, “existing power” which considers depreciated power plants can sell their energy at lower prices in shorter term contracts. The Concessions Law establishes three kinds of revisions to final consumer tariffs: annual tariff resetting, ordinary tariff revision and extraordinary tariff revisions. Distribution companies’ pricing aims to maintain a concessionaire’s operating margins constant by allowing for tariff gains due to costs beyond management’s control and permitting the concessionaire to retain any efficiency gains achieved for defined periods of time. Tariffs to end users are also adjusted according to the variation of costs incurred in purchasing electricity. Ordinary tariff revision takes into account the entire tariff setting structure for the company, including the costs of providing services, the costs of purchasing energy and the return for the investor. Under their concessions, Coelce and Ampla are subject to tariff revisions every four and five years, respectively. The asset base consists of the market replacement value depreciated during their useful life from an accounting point of view and the rate of return for the assets is based on the Weighted Average Cost of Capital, or WACC, of a model company. The operating and maintenance costs reflected in the tariff are calculated based on the model company which considers the singular characteristics of the distribution concession area.

In the event that the cost components over which management does not exert influence, such as energy purchases and taxes, increases significantly within the period between two annual tariff adjustments, the concessionaire may make a request to ANEEL to charge those costs to the final customers. Aneel is considering amendments to the existing regulations, third tariff review cycle, minimum technical requirements for electronic meters and tariff structure. For these three projects, ANEEL has held three public hearings in early 2011. The companies or consortia seeking to build or operate hydroelectric generation facilities with a capacity greater than 30 MW, or transmission facilities in Brazil, must use a competitive bidding process. Concessions granted to the holder give the right to generate, transmit or distribute electricity, as the case may be, in a given concession area for a certain period of time. That certain period of time is limited to 35 years for new generation concessions and 30 years for new transmission and distribution concessions. Existing concessions must be renewed at the discretion of the Brazilian government for a period equal to its initial period. In the regulated environment (ACR), electricity distribution companies buy the electricity through bids that are regulated by ANEEL and organized by the Chamber of Electricity Commercialization, CCEE. Distributors must buy electricity at public bids. There are three types of regulated bids: new energy bids, existing energy bids and adjustment bids. The government has also the right to call special bids for renewable electricity (biomass, small hydro, solar and wind). ANEEL and CCEE hold the bids annually. The contracting system is multilateral, with generating companies entering into contracts with all distributors who call for bids. Unregulated Environment, or ACL, include the sale of electricity between generation concessionaires, independent producers, self producers, sellers of electricity, importers of electricity, unregulated and special consumers. The ACL also includes contracts in place between generators and distributors until their expiration, at which point new contracts may be entered into under the terms of the new regulatory framework. Brazil created a special mechanism to share hydrological risk between all hydro generators, called Reallocating Energy Mechanism (MRE). Each hydro power plant has an assigned energy certificate which defines both the proportion of the total generated hydro energy owned by this plant and the maximum energy amount that this plant can sale through contracts. Differences between actual production and the assigned energy must be traded at a regulated fixed tariff (approximately $ 4/MWh). The spot price is used to value the purchase and sale of electric power in the short term market. According to the law, CCEE is responsible for the setting of the electricity price in the spot market. This price is calculated based on marginal costs, modeling future operating conditions and setting a curve based on merit, with variable costs of thermal units and opportunity costs for hydro plants, resulting in a price for each subsystem for the following week In 2010 there were four bidding processes for new generation projects, in which 99 plants were awarded for a total of 17,054 MW, distributed among 89 plants from alternative sources (2,892 MW), three large hydropower plants (13,353 MW) and seven medium sized hydro plants (809 MW).

Chile 3.1. Industry structure The electricity industry in Chile is divided into three business segments: generation, transmission and distribution. The generation segment consists of companies that produce electricity. They sell their production to distribution companies, unregulated customers, or to other generation companies. The transmission segment consists of companies that transmit at high voltage the electricity produced by generation companies. Finally, the distribution segment is defined for regulatory purposes to include all electricity supply to final customers at a voltage no higher than 23 kV. The electricity sector in Chile is regulated pursuant to the Chilean Electricity Law, contained in Decree with force of Law No. 4 of 2006 of the Ministry of Finance, published in the Official Gazette on February 5, 2007, which set the revised, coordinated and systematized text of the DFL No. 1/82 and its amendments, which is known as the Chilean Electricity Law and its respective rules included in the DS Nº327 of 1988. In Chile there are four separate interconnected electricity systems. The main systems that cover the most populated areas of Chile are the Sistema Interconectado Central, SIC, that services the central and south central part of the territory, where 93% of the Chilean population lives, and the Sistema Interconectado del Norte Grande, SING, which operates in the northern part of the country, where most of the mining industry is located. According to the 2002 census, 6.1% of the Chilean population lives in the territory serviced by the SING. In addition to the SIC and the SING, there are two isolated systems in southern Chile that provide electricity in remote areas. The operation of electricity generation companies in each of the two major interconnected electricity systems is coordinated by their respective dispatch center, (CDEC), an autonomous entity that involves industry groups, transmission companies and large customers. CDECs coordinate the operation of their system as efficient markets for the sale of electricity, in which the lowest marginal cost producer is usually used to satisfy demand. As a result, at any specific level of demand, the appropriate supply will be provided at the lowest possible cost of production available in the system at any moment. Twice a year (in April and October), the CNE calculates the Precio de Nudo (node price), or energy and capacity regulated prices that distribution companies pay to generators. In 2005, bid processes were introduced for distribution companies’ energy supply, and therefore after 2010 the energy “node price” will be necessary only to set the maximum offer price for each energy bid to regulated customers. The CNE also prepares the Indicative Plan, a ten year guide for the expansion of the generation and transmission system. Generation companies may sell to final unregulated customers or to other generation companies under contracts with freely determined terms. To balance their contractual obligations with their dispatch, generators have to trade deficit and surplus electricity at the spot market price, which is set hourly by each CDEC, based on the marginal cost of production of the next kWh to be dispatched. Regulated customers are those with a maximum consumption capacity not exceeding 0.5 MW. Customers between 0.5 and 2 MW may choose their status as regulated or unregulated. Customers with capacity needs over 2 MW are unregulated. Since 2005 all new contracts between generation and distribution companies for the supply to regulated customers must arise from international bids which have a maximum offer energy price based on the average price paid by the unregulated customers at the time that the bid is made, which is calculated twice a year by the CNE.

Under the bid system, all distribution companies will have electricity contracts from 2011 onwards. Distribution companies may also pay for their capacity consumption at the capacity node price determined by the CNE, and calculated based on the marginal cost of increasing the existing capacity of the electricity system with the least expensive dispatch by any generating facility. Since transmission assets are built pursuant to concessions granted by the government, the law requires a company to operate on an “open access” basis, in which users may obtain access to the system by contributing towards the costs of operating, maintaining and, if necessary, expanding the system. Sub transmission systems are high voltage lines over 23 kV, used mainly by customers. There are 7 sub-transmission systems defined by law. Chilectra has most of the SIC 3 system. Every four years a study to assess the optimal system adapted to demand is performed. On September 21, 2010, the study was submitted to the CNE and is currently being revised. Sub transmission systems are paid for mainly by customers based on the values determined by the Ministry of Finance Decree. Generators and non-regulated customers only pay for the lines they use in each system. The tariffs charged by distribution companies to final customers are determined by the sum of the cost of electricity purchased by the distribution company, a transmission charge and the “value added by the distribution network,” or VAD, which allows distribution companies to recover their operating costs. The VAD is based on a “model company” and includes: selling, general and administrative distribution costs; maintenance and operating costs of distribution assets; energy cost and losses; and an expected return on investment, before taxes, of 10% per year in real terms based on the replacement cost of assets used for distribution. With this purpose, the CNE selects a company, to which it applies efficiency guidelines which results in a cost structure for the “model company” for each Typical Distribution Area. The VAD is set every four years. The CNE classifies companies into groups, according to Typical Distribution Areas, based on economic factors that group companies with similar distribution costs due to population density, which determines equipment density in the network. Actual return on investment for a distribution company depends on its performance relative to the standards chosen by the CNE for the model company. The tariff system allows for a greater return to distribution companies that are more efficient than the model company. Tariff studies are performed by the CNE and distribution companies. Tariffs are estimated as a weighted average of the results of the CNE-commissioned study and the companies’ study, with the results of the CNE’s study bearing twice the weight of the companies’ results. Preliminary tariffs are tested to ensure that they provide an average actual annual internal rate of return between 6% and 14% on the replacement cost of electricity related assets for the entire distribution segment. The last process for setting distribution tariffs was held in 2008, and will be in effect until November 3, 2012. If a rationing decree is enacted in response to prolonged periods of electricity shortages, severe penalties may be imposed on generation companies that contravene the decree. A severe drought is not considered a force majeure event. Generation companies may also be required to pay fines to the regulatory authorities, related to system blackouts due to any generator’s operational mistake, including failures related to the coordination duties of all system agents as well as to make compensatory payments to electricity consumers affected by shortages of electricity.

Others Chile has numerous laws, regulations, decrees and municipal ordinances that may raise environmental considerations. Among them are regulations relating to waste disposal (including the discharge of liquid industrial wastes), the establishment of industries in areas in which they may affect public health, and the protection of water for human consumption. Environmental Law No. 19,300 was enacted in 1994 and implemented by several rules, such as Environmental Impact Assessment System Rule issued in 1997 and modified in 2001. This law requires companies to conduct environmental impact study or declaration of any future generation or transmission projects. In January, 2010, Law No. 19,300 was modified by Law No. 20,417, introducing changes in the environmental assessment process and in the public institutions involved in it. Consequently, environmental assessment process is coordinated by the Environmental Assessment Service, and not by Chilean Environmental Commission, or Conama, that was repealed. On April 1, 2008, Law No. 20,257, which is an amendment to the General Services Law, was enacted. The purpose of the amendment is to promote the use of NCRE. This law defines the different types of technologies considered as NCRE, and establishes the obligation of generators between 2010 and 2014, to supply 5% of the total energy contracted from August 31, 2007, to be of such type, and to progressively increase this percentage 0.5 percentage points annually up to 10% as of 2024. Endesa Chile owns water rights, constitutionally and legally recognized, that allow a full and permanent use of water resources in the generation units of society. According to Chilean law, the owners of water rights must pay an annual fee for unused water rights. 4. Colombia 4.1. Industry structure In 1994, Colombia’s Congress approved major reforms to the utility industry. These reforms contained in Act 142 of 1994 (“LSPD”), known as the Residential Public Utilities Law, and the law 143 of 1994, were the result of constitutional amendments approved in 1991 and created the basic legal framework currently governing the electricity sector in Colombia. The most significant reforms include opening the electricity industry to private sector participation, functional segregation of the electricity sector in four different activities, namely generation, transmission, distribution and commercialization, the creation of a wholesale electricity market open and competitive, the regulation of transmission and distribution activities as regulated monopolies, and the adoption of universal access principles applicable to transmission and distribution grids. The Colombian Electricity Act sets out the principles for the electricity industry, which are implemented through the resolutions enacted by the Energy and Gas Regulatory Commission, or “CREG.” Such principles are: efficiency (the correct allocation and use of resources and the supply of electricity at minimum cost); quality (compliance with technical requirements); continuity (continuous electricity supply without unjustified interruptions); adaptability (the incorporation of modern technology and administrative systems to promote quality and efficiency); neutrality (impartial Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 95 2010 Annual Report Regulatory framework of the electricity industry treatment to all electricity consumers); solidarity (the provision of funds by high income consumers to subsidize the subsistence consumption of low income consumers); and fairness (an adequate and nondiscriminatory supply of electricity to all regions and sectors of the country). The market share for generators and traders is limited. The limit for generators is 25% of the Colombian system Firm Energy. Firm Energy refers to the maximum electric energy that a generation plant is able to deliver on a continuous basis during a year, in extremely dry conditions; for instance, in the case of the El Niño phenomenon. Similarly, a trader may not account for more than 25% of the trading activity in the Colombian NIS. Limitations for traders take into account international energy sales. Market share is calculated on a monthly basis and traders have up to six months to reduce their share when the limit is exceeded. Such limits are applied to economic groups, including companies that are controlled by, or under common control with, other companies. In addition, generators may not own more than a 25% interest in a distributor, and vice versa. However, this limitation only applies to individual companies and does not preclude cross ownership by companies of the same corporate group. A generator, distributor, trader or an integrated company, i.e. a firm combining generation, transmission and distribution activities, cannot own more than 15% of the equity in a transmission company if the latter represents more than 2% of the national transmission business in terms of revenues. A distribution company can have more than 25% of an integrated company’s equity if the market share of the last company is less than 2% of the national generation business. A company created before enactment of Law No. 143 is banned from merging with another company created after Law No. 143. The generation sector is organized on a competitive basis with companies selling their production on the electricity pool market, the wholesale market, at the spot price or by long-term private contracts with other participants and unregulated customers at freely negotiated prices. The Colombian NIS is the system formed by generation plants, the interconnection grid, regional transmission lines, distribution lines and consumer loads. The spot price is the price paid by the participant in the wholesale market for energy dispatched under the direction of the National Dispatch Center (CND). The hourly spot price paid for energy reflects prices offered by generators in the wholesale market and the respective supply and demand conditions. Generators connected to the Colombian NIS can also receive “reliability payments” which are a result of the Firm Energy Obligation that they provide to the system. The Firm Energy Obligation (OEF) is a commitment on the part of generation companies backed by its physical resource capable of producing firm energy during scarcity periods. The generator that acquires an OEF will receive a fixed compensation during the commitment period, whether or not the fulfillment of its obligation is required. To receive reliability payments, generators have to participate in firm energy bids by declaring and certifying their firm energy. Until November 2012, the transition period, the firm energy supply for reliability purposes will be assigned proportionally to the declared firm energy of each generator. Beyond the transition period, the additional firm energy required by the system will be allocated by bids. The only auction for this period took place on May 6, 2008, where existing generators participated with new generation projects while meeting the established market share limits. The purchase and sale of electricity can take place between generator and distributors acting in their capacity as traders, and unregulated customers. There are no restrictions for new entrants into the market as long as the participants comply with the applicable laws and regulations.

In the wholesale market, an hourly spot price for all dispatched units is established based on the offer price of the highest priced generating dispatched unit for that period. The CND receives price bids each day from all the generators participating in the wholesale market. These bids indicate prices and the hourly available capacity for the following day. Based on this information, the CND guided by “optimal dispatch” principle (which assumes an infinite transmission capacity through the network), ranks the generators according to their offer price, starting with the lowest bid, and establishing the merit order, on an hourly basis, determining which generator will be dispatched the following day to satisfy expected demand. The price for all generators is set as the most expensive generator dispatched in each hourly period under the optimal dispatch. Additionally, the CND performs the “planned dispatch,” which takes into account the limitations of the network as well as every other condition necessary to satisfy the energy demands expected for the following day, in a safe, reliable and cost-efficient manner, based on costs. The cost differences between “planned dispatch” and” optimal dispatch” are called restriction costs. The net value of these restrictions is assigned proportionally to all the traders within the Colombian NIS, according to their demands of energy, who transfer these costs to the final customer. Some generators have initiated legal proceedings arguing that recognized prices do not cover the costs associated with these restrictions. Transmission companies which operate at least at 220 kV compose the National Transmission System, or NTS. They are required to provide access to third parties on equal conditions and are authorized to collect a tariff for their services. The transmission tariff includes a connection charge that underwrites the cost of operating the facilities, and a usage charge, which applies only to traders. CREG guarantees an annual fixed income to transmission companies. Income is determined by the new replacement value of the networks and equipment, and by the resulting value of bidding processes awarding new projects for the expansion of the NTS. This value is allocated among the traders of the NTS in proportion to their energy demand. Distribution is defined as the operation of local networks below 220 kV. Any user may have access to a distribution network for which it pays a connection charge. CREG regulates distribution prices that should permit distribution companies to recover costs, including operating, maintenance and capital costs operating efficiently. Distribution charges are set by CREG for each company based on the replacement cost of the existing distribution assets, cost of capital, as well as operational and maintenance costs that vary depending on the voltage level. A new remuneration methodology for the distribution was defined by CREG in 2008 which set the Weighted Average Cost of Capital (WACC) at 13.9% before taxes, for assets operating at 34.5 kV or less, and 13% before taxes for assets operating above 34.5 kV. CREG also defined a new methodology for the calculation of distribution charges, defining an incentive scheme for administrative, operational and maintenance costs, service quality and energy losses. During 2009, after auditing the information reported by the companies, CREG defined the new distribution charges applicable from 2009 until 2013. The retail market is divided into regulated and unregulated customers. Customers in the unregulated market may freely contract for electricity supply directly from a generator or a distributor, acting as traders, or from a pure trader. The unregulated customer market consists of customers with a peak demand of more than 0.1 MW or a minimum monthly consumption of 55 MWh.

It may be conducted by generators, distributors or independent agents, which comply with certain requirements. Parties freely agree upon trading prices for unregulated customers. Trading to regulated customers is subject to the “regulated freedom regime” under which tariffs are set by each trader using a combination of general cost formulas given by CREG and individual trading costs approved by CREG for each trader. Since CREG approves limits on costs, traders in the regulated market may set lower tariffs for financial reasons. Tariffs include, among other things, energy procurement costs, transmission charges, distribution charges and a trading margin. 4.2. Others Law No. 99 of 1993 provided the framework for environmental regulation and established the Ministry of the Environment as the authority for determining environmental policies. The Ministry defines issues and executes policies and regulations that focus on the recovery, conservation, protection, organization, administration and use of renewable resources. According to Law No. 99, generators which have a total installed nominal capacity above 10 MW are required to contribute to the conservation of the environment through a payment for their activities. Hydroelectric power plants must pay 6% of their energy sales; thermoelectric plants must pay 4% of their energy sales. This payment is made monthly to the municipalities and environmental corporations where these facilities are located. 5. Peru 5.1. Industry structure The regulatory framework applicable to the Peruvian electricity industry is given by: the Law of Electricity Concessions (Decree Law No. 25,844) and its ancillary regulations, and the Supplementary Law No. 27,699 of Organismo Supervisor de la Inversión en Energía y Minería (Energy and Mining Investment Supervisor Authority) Osinergmin, the electricity sector regulatory authority, in charge of the resolution of controversies that arise within this institution. Some of the characteristics of the regulatory framework are (i) the separation of the three main activities: generation, transmission and distribution; (ii) freedom of prices for the supply of energy in competitive market conditions; (iii) a system of regulated prices based on the principle of efficiency shared with a bidding regime; and (iv) private operation of the interconnected electricity systems subject to the principles of efficiency and quality of service. There is one interconnected system, the Sistema Eléctrico Inteconectado Nacional (SEIN), and several isolated regional and smaller systems that provide electricity to specific areas. Service provided by electricity companies has to comply with technical standards, otherwise companies may be charged with fines imposed by Osinergmin.

Generators can sell energy directly to large customers and transfer the deficit or surplus between contracted energy and actual production in the pool at spot price. Distribution companies and large customers that have entered into private supply contracts with generation companies pay the contractual price (which includes the tolls and compensation for the use of the transmission system), and also pay a toll to distribution companies for the use of their network. Customers with a capacity demand of less than 200 kW are considered regulated customers, and the supply of their energy is defined as a public service. Customers whose annual demand is within the range of 200 kW and 2,500 kW are free to choose to be considered regulated or unregulated customers. In 2008, due to gas transport and electricity transmission problems, Osinergmin defined a new rule to calculate spot prices. That will be in place until December 2013. Decree 049 2008 established two models, one theoretical dispatch without any restrictions and a real dispatch considering the restrictions. The spot price is obtained from the theoretical dispatch, and the additional cost of operation associated with the system restrictions are paid to the affected generators, through a mechanism established by the authority. Generators receive a capacity payment which main component is a resultant of an annual calculation of every power plant’s capacity. Every year, Osinergmin sets the power price that defines the total amount to assign to each generator. Transmission activities are divided into two categories: principal, that is for common use and allows the flow of energy through the national network and secondary, which is one of those lines that connect to a power plant with the system or a substation to a distribution company or end user. Law No. 28,832, enacted in 2006, also defined guaranteed systems. The principal and guaranteed system lines are accessible to all generators and allow electricity to be delivered to all customers. The transmission concessionaire receives an annual fixed income and receives tariff revenues and connection tolls reflecting a charge per kW. The secondary and complementary system lines are accessible to all generators, but are used to serve only certain customers who are responsible for making payments related to their use of the system. The Efficient Development Law (Law No. 28,832) establishes a bidding regime for the acquisition of energy and capacity by distributors establishing a mechanism to determine prices during the life of a contract. The approval of this mechanism is important to generators, because it establishes a mechanism for determining price for the duration of a contract that is not fixed by the regulator.

Only a small part of the electricity purchased by distribution companies, included in old contracts, is still maintained at bus bar prices. Bus bar prices are set annually by Osinergmin, and are the maximum prices for electricity purchased by distribution companies that can be transferred to regulated customers, in those contracts. The electricity tariff for regulated customers includes charges for capacity and energy for generation and transmission (bus bar prices) and for the VAD which considers a regulated return over capital investments, operating and maintenance fixed charges and a standard percentage for energy distribution losses. Generators that have a plant with an installed capacity greater than 500 KW, require a concession from the Ministry of Energy and Mining (MINEM). Similarly, the generators that operate power plants with an installed capacity exceeding 500 KW require an authorization from the MINEM. A concession for electricity generation activity is an agreement between the generator and MINEM, while an authorization is merely a unilateral permit granted by the Ministry. Authorizations are granted by the MINEM for an unlimited period of time, although their termination is subject to the same considerations and requirements as the termination of a concession under the procedures set forth in the Law of Electrical Concessions (Law No. 25,844) and related regulations. In 2009, MINEM performed studies that concluded that SEIN would not allow the unavailability of a larger power plant. It recommended the implementation of a cold reserve to ensure continuity. ProInversión called for bids on the first cold reserve, which offered 800 MW in three projects. Only two were awarded: Talara (200 MW to EEPSA, a company related to Enersis) and Llo (400 MW to Enersur). They will receive payments for capacity availability and payment of fuel costs when they must generate. 5.2. Others The environmental legal framework applicable to energy related activities in Peru is set forth in the Environmental Law (Law No. 28,611) and in the Regulation for Environmental Protection regarding Electricity Activities (Supreme Decree 029 94 EM). In 2008, MINEM enacted Decree 050-2008 to promote the generation of electricity through. Such Decree establishes that 5% of demand of the SEIN must be supplied by the use of NCRE. This 5% goal could increase every five years. The technologies considered renewable resources are: biomass, wind, tidal, geothermal, solar and mini hydro (less than 20 MW) Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next Description of the business by Country Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 102 Enersis 2010 Annual Report 1. Electricity generation Our electricity generation business is conducted primarily through our subsidiary Endesa Chile. In this segment, the Enersis Group has operating subsidiaries in Argentina, Brazil, Chile, Colombia and Peru. In all, the installed capacity amounted to 14,832.50 MW as of December 2010 and the consolidated electricity generation was 56,699 GWh, while energy sales totaled 63,431 GWh. In the electricity industry, the segmentation of the business between hydroelectric and thermal generation is natural as the variable costs of generation are different for each form of generation. Thermal generation requires the purchase of fossil fuels and hydroelectric generation needs water from reservoirs and rivers. 58% of our consolidated generating capacity comes from hydroelectric sources while 41% is thermal and 1% wind sources. Therefore, the commercial policy the generation company defines is relevant in terms of managing the business properly.

Argentina 4.1. Electricity generation Enersis participates in electricity generation in Argentina through Endesa Costanera and Hidroelectrica El Chocón, in which it controls directly and indirectly, a 41.8% and 39.2% of ownership, respectively. These companies have a total of five power plants, with total installed capacity of 3,652 MW. This capacity represented in 2010, 13% of the installed capacity of the argentine SIN. Electricity generation of the Enersis Group reached 10,940 GWh, 9.5% of the country total generation, with hydroelectricity representing 27.2% of production. Physical sales of electricity reached 11,378 GWh, 10.3% of total sales. Endesa Costanera and El Chocón participate in companies in charge of the operation of two combined cycles, initiative coordinated by Fondo para Inversiones Necesarias que Permitan Incrementar la Oferta de Energía Eléctrica en el Mercado Eléctrico Mayorista (FONINVEMEM), with a 5.51% and 15.35% share of property, respectively. The commercial operation as combined cycles of Termoelectrica Manuel Belgrano and Termoelectrica San Martín began in 2010. The operation as a combined cycle determined the effective date of the Contract for the Operation and Management of Plant Maintenance and the Supply Contract. Consequently, the companies that participate in FONINVEMEM, among them, Endesa Costanera and El Chocón, began to recover their credits with the cash flows generated by the Project, through a ten year contract to sell its generation to the MEM, managed by CAMMESA. By December 31,2010, collections have responded to agreed plan. Other generators connected to the argentine SIN are: AES Alicura, SADESA, Capex, Petrobras, Pampa Generación and Pluspetrol. 4.1.1. Endesa Costanera Located in the city of Buenos Aires, it has an installed capacity of 1,138 MW using natural gas or fuel oil. It is the largest facility of its kind in Argentina. It also operates two combined-cycle plants of 859 MW and 327 MW each, with a total installed capacity of 2,324 MW. Net generation in 2010 was 7,965 GWh and total sales 8,018 GWh. Electricity demand in the Argentine system recorded a 5.9% increase when compared to 2009. The gas supply was 15% lower than the previous year, and therefore the greater thermal requirements were satisfied by an increase in the consumption of liquid fuels, both in conventional and combined cycle units. On the regulatory side, the MEM continued to be intervened by the authority in terms pricing of the hourly energy sale price and the payment for generators production. Due to these measures, the Company received only partial payment of its monthly credits. In 2010, the company´s financial priority was satisfying the operating cash flow needs of the power plant, being able to reprogram short term debt maturities. Operations were characterized by full dispatch of all Endesa Costanera units (maximum thermal requirement), from the beginning of the year until practically the third quarter of 2010, time in which, mainly due to temperature, dropped significantly, leaving the units available condition. Notwithstanding the foregoing, the total generating capacity of the plant available to the system was similar to that of 2009. In terms of maintenance, during 2010 the projected plans were achieved, performing all maintenance for both combined Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 106 Enersis 2010 Annual Report cycles, according to the provisions of existing long-term maintenance contracts. The conventional turbo gas units started their programmed maintenance in September, according to the denominated Winter Plan, intervening units Nº 7 and Nº 4. Maintenance was also performed on ancillary services. 4.1.2. Hidroeléctrica El Chocón It is located in the provinces of Neuquén and Río Negro, and operates one artificial reservoir hydroelectric plant of 1,200 MW and another of 128 MW that use the waters of the Limay and Collón Curá rivers, with a total installed capacity of 1,328 MW. During 2010, the hydrology of the Limay basin behaved below the historical average, and therefore, the operational criteria applied by the organism in charge of dispatch, was to limit the use of the accumulated strategic reserves. This method resulted in strengthening the energy reserves of Comahue. The resulting dispatch of the El Chocon reservoir at the end of the year led to 2,975 GWh net generation of El Chocon-Arroyito, leaving the level of the reservoir at 378.72 m.s.n.m. The energy reserve of the Comahue reservoirs was 6,224 GWh; of which 2,989 GWh correspond to El Chocon generation, both figures measured in terms of the minimum level condition of the Extraordinary Operation Range. Commercially, the company focused on assuring economic and financial sustainability, concentrating its attention on the diversification of its customer base, by commercialing in alternative markets at spot price. The study on the Mercado a Término continued, with the purpose of offering solid sand adapted solutions to its needs. In that sense, we tried to anticipate the detection of business opportunities from considering each client as part of company management, building alliances with each one of them, assuring the benefits of a long term relationship, keeping customers satisfied. Also, the sale of new energy backed by Central Arroyito was optimized, due to level elevation works. As a result of the administration, it was possible to strengthen term contract market share with physical back up. During the year, spot market sales reached 1,949 GWh and contract sales to customers reached 1,411 GWh. In order to do so, 385 GWh were purchased in the MEM, obtaining a variable margin of 318 million argentine pesos.

Electricity distribution Enersis participates in electricity distribution in Argentina through its subsidiary Edesur in which it has a 65.4% direct and indirect shareholding. Market share of our Argentine subsidiary, in terms of physical sales, was approximately 15%. Other distributors in the Argentine electricity system are Empresa Jujeña de Energía (EJESA), Empresa de Distribución de Energía de Tucumán (EDET), Empresa Distribuidora de Energía de Santiago del Estero (EDESE), Empresa Distribuidora y Comercializadora Norte (EDENOR) and Empresa de Distribución de la Plata (EDELAP). 4.2.1. Edesur The main objective of Edesur is to distribute and commercialize electricity in the southern part of the city of Buenos Aires, comprising two-thirds of the city of Buenos Aires and twelve districts of the province of Buenos Aires, covering 3,309 sq.km for 95 years from August 31, 1992. This period includes an initial one of 15 years and eight additional ones of 10 years each. On February 5, 2007, the electricity regulatory authority (ENRE) resolved to extend the initial period by five years, as of the completion of the tariff renegotiation process (RTI). The concession contract establishes the obligation of Edesur to supply electricity at the request of the owners or inhabitants of properties within its concession area, meet certain quality standards related to electricity supplied, and comply with operational requirements with respect to the maintenance of the distribution assets and bill customers on the basis of effective metering. In 2010, Edesur provided electricity to 2,352,720 customers, 2.1% more than the year before. Of the total, 87.2% are residential customers, 11.4% commercial, 1.0% industrial and 0.4% other users. Energy sales amounted to 16,759 GWh, representing 5.0% increase when compared to2009. This was distributed 41.1% to the residential sector, 25.9% to the commercial sector, 8.4% to industry and 24.6% to others. The energy loss index reached 10.5% in 2010.

We have audited the accompanying consolidated statements of financial position of Enersis S.A. and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the years ended December 31, 2010, 2009 and 2008. These consolidated financial statements (including the related notes) are the responsibility of Enersis S.A.’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We did not audit the financial statements as of December 31, 2010 and 2009 of certain subsidiaries, which statements reflect total assets constituting 42.46% and 41.27%, respectively, of consolidated total assets as of those dates, and total revenues constituting 42.45%, 45.68% and 47.59%, respectively, of consolidated total revenues for the years ended December 31, 2010, 2009 and 2008. Those statements were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for those certain subsidiaries, is based solely on the report of the other auditors. We conducted our audits in accordance with auditing standards generally accepted in Chile. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, based on our audits and the report of the other auditors, such consolidated financial statements present fairly, in all material respects, the financial position of Enersis S.A. and subsidiaries as of December 31, 2010 and 2009 and the results of their operations and their cash flows for the years ended December 31, 2010, 2009 and 2008 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. The translation of these consolidated financial statements into English has been made solely for the convenience of readers outside Chile.

The Group is assessing the impact of the application of IFRS 9 from its effective date. In Management’s opinion, the application of other standards, interpretations and amendments pending application will not have a significant effect on the consolidated financial statements of Enersis and subsidiaries. 2.3. Responsibility for the information and estimates made. The Company’s Board is responsible for the information contained in these consolidated financial statements and expressly states that all IFRS principles and standards that are applicable to the Group have been fully implemented. In preparing the consolidated financial statements, certain estimates made by the Company’s Management have been used in order to quantify some of the assets, liabilities, income, expenses and commitments recorded in such statements. These estimates basically refer to: • The valuation of assets and goodwill to determine the existence of impairment losses (see Note 3.e). The assumptions used to calculate the actuarial liabilities and obligations to employees (see Note 23). The useful life of property, plant and equipment and intangible assets (see Notes 3.a and 3.d). The assumptions used to calculate the fair value of financial instruments (see Notes 3.g.5. and 20). Energy supplied to customers and not invoiced at the end of each year. Certain assumptions inherent in the electricity system affecting transactions with other companies, such as production, customer billings, energy consumption, etc. used on the estimations of electricity system settlements. These settlements must occur in the corresponding final settlement dates, which have not occurred as of the date of issuance of the consolidated financial statements, and could affect the balances of assets, liabilities, income and expenses recorded in such statements. The probability that uncertain or contingent liabilities will be incurred and their related amounts (see Note 3.l). Future disbursement for the closure of facilities and restoration of land (see Note 3.a). • • • • • • • Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 196 Enersis 2010 Annual Report • The tax results of the various subsidiaries of the Group that will be reported to the respective tax authorities in the future, which have served as the basis for recording different balances related to income taxes in the current consolidated financial statements (see Note 3.o). Although these estimates have been based on the best information available at the date of issuance of the consolidated financial statements presented herein, it is possible that events may occur in the future that will require a change (increase or decrease) to these estimates in subsequent years, which would be done prospectively, recognizing the effects of such estimation change in the corresponding future consolidated financial statements. 2.4. Subsidiaries and jointly-controlled entities Subsidiaries are defined as entities in which the Parent Company controls the majority of the voting rights or, should that not be the case, is authorized to direct the financial and operating policies of such entities. Jointly-controlled entities are entities in which the situation described in the preceding paragraph exists as a result of an agreement with other shareholders and control is exercised jointly with them. Appendix No. 1 of these consolidated financial statements, titled “Enersis Group Companies,” described Enersis relationship with each of its subsidiaries and jointly- controlled entities. 2.4.1. Changes in the scope of consolidation During 2010 there were no significant changes in Enersis Group’s scope of consolidation. In 2009 the following transactions occurred that changed the Group’s scope of consolidation: On February 25, 2009, our subsidiary Compañía Distribuidora y Comercializadora de Energía S.A. (“Codensa S.A.”) made a capital contribution amounting to ThCh$ 23,744,357 in Distribuidora Eléctrica de Cundinamarca S.A. (“DECA”), that was used to subscribe and pay 489,997 shares, that represents a 48.997% of DECA’s ownership interest. The remaining 51.003% ownership interest in DECA was subscribed and paid by Empresa Eléctrica de Bogotá, a company that has entered into an agreement with Codensa S.A. for the joint control of DECA. Subsequently, on March 13, 2009, DECA acquired an 82.34% ownership interest in Empresa de Energía de Cundinamarca for ThCh$ 48,460,838. As a result of this acquisition DECA recognized goodwill amounting to ThCh$ 14,457,069 (see Notes 5.c and 14). The section titled “Changes in the scope of consolidation,” included as Appendix No. 2 to the consolidated financial statements, shows the companies included within the scope of the Group’s consolidation, together with a detail of the Group’s respective ownership interest percentages. 2.4.2. Companies consolidated with less than 50% share. Although Enersis Group holds less than a 50% share in Codensa and in Empresa Generadora de Energía Eléctrica S.A. (“Emgesa”), they are deemed to be subsidiaries since the Group exercises control over the entity, directly or indirectly, through contracts or agreements with shareholders, or as a consequence of its structure, composition and shareholder classes.

Companies not consolidated with greater 50% share. Although Enersis Group holds more than 50% interest in Centrales Hidroeléctricas de Aysén, S.A. (hereinafter “Hidroaysén”), Hydroaysén is considered to be a jointly- controlled entity because the Group, through contracts and agreements with shareholders, exercises joint control of the entity. 2.5. Basis of consolidation and business combinations The subsidiaries are consolidated and all their assets, liabilities, income, expenses and cash flows are included in the consolidated financial statements after making the adjustments and eliminations related to intra-Group transactions. Jointly-controlled entities are consolidated by using the proportional consolidation method. The Group recognizes, line by line, its share of the assets, liabilities, income and expenses of such entities, so that the aggregation of balances and subsequent eliminations, takes place only in the proportion of Group’s ownership interest in them. The results of subsidiaries and jointly-controlled entities are included in the consolidated comprehensive income statement, from the effective date of acquisition until the effective date of disposal or termination of joint control, as appropriate. The consolidation of the operations of the Parent Company and its subsidiaries, as well as the jointly-controlled entities, was performed applying the following basic principles: 1. At the date of acquisition, the assets, liabilities and contingent liabilities of the subsidiary or jointly-controlled entity are recorded at market value. In the event that there is a positive difference between the acquisition cost and the fair value of the assets and liabilities of the acquired entity, including contingent liabilities, corresponding to the parent’s share, this difference is recorded as goodwill. In the event that the difference is negative, it is recorded with a credit to income. 2. Non-controlling interests in equity and in the financial results of the 3. consolidated subsidiaries are presented, respectively, under the line items “Non-controlling interests” in the consolidated statement of financial position and “Net Income attributable to non-controlling interests” and “Other comprehensive income attributable to non controlling interests” in the consolidated statement of comprehensive income. Translation of financial statements of foreign companies with functional currencies other than the Chilean peso is performed as follows: a. For assets and liabilities, the prevailing exchange rate on the closing date of the financial statements is used. For items in the comprehensive income statement, the average exchange rate for the year is used. Equity remains at the historical exchange rate from the date of acquisition or contribution, and for retained earnings at the average exchange rate at the date of generation. b. c. Exchange differences arising in the conversion of the financial statements are recognized within the heading “Exchange difference on translation” within the consolidated statement of comprehensive income: Other comprehensive income. (see Note 24.2). Translation adjustments that existed at the Group’s transition date to IFRS, January 1, 2004, were deemed to be zero and transferred to reserves, using the exemption for that purpose in IFRS 1 “First time Adoption of IFRS” (see Note 24.5).

Reclassifications The Group has made certain reclassifications to the consolidated financial statements as of December 31, 2009 and 2008, as a result of new instructions issued on March 25, 2010 by the SVS through Circular No. 1975. These reclassifications relate mainly to regrouping of financial assets and liabilities within current or non-current, as applicable, and regrouping items under the statements of comprehensive income, but they do not affect the operating income Note 3. Accounting Principles Applied The main accounting policies used in preparing the accompanying consolidated financial statements were as follows: a) Property, plant and equipment Property, plant and equipment are valued at acquisition cost, net of accumulated depreciation and any impairment losses it may have experienced. In addition to the price paid to acquire each item, the cost also includes, where appropriate, the following concepts: • Finance expenses accrued during the construction period that are directly attributable to the acquisition, construction or production of qualified assets, which require substantial period of time before being ready for use such as, for example, electricity generating or distribution facilities. The interest rate used is that of the specific financing or, if none exists, the mean financing rate of the company carrying out the investment. The mean financing rate depends principally on the geographic area and ranges between 5.19% and 7.46%. The amount capitalized for this concept amounted to ThCh$ 15,137,380, ThCh$ 9,173,217 and ThCh$ 9,470,558 for the years ended December 31, 2010, 2009 and 2008, respectively. Capitalized employee expenses directly related to work in progress for the years ended December 31, 2010, 2009 and 2008, were ThCh$ 26,741,111, ThCh$ 16,723,291 and ThCh$ 18,611,427, respectively. Future disbursements that the Group must make to close their facilities are incorporated into the value of the asset at present value, recording the corresponding provision in accounting. On a yearly basis, the Group reviews their estimate of these future disbursements, increasing or decreasing the value of the asset based on the results of this estimate. (see Note 22). Items acquired before the Group’s date of transtion to IFRS, January 1, 2004, include, where appropriate, asset reappraisals permitted in various countries to adjust the value of the property, plant and equipment for inflation as of that date. (see Note 24.5). • • • pages control previously next Construction work in progress items are transferred to operating assets once the testing period has been completed when they are available for use, at which time depreciation begins. 199 Financial Statements Consolidated Expansion, modernization or improvement costs that represent an increase in productivity, capacity or efficiency or a longer useful life are capitalized as a greater cost for the corresponding assets. The replacement or overhaul of whole components that increase the asset’s useful life, or its economic capacity, are recorded as an increase in value for the respective assets, derecognizing the replaced or overhauled components. Periodic maintenance, conservation and repair expenses are recorded directly in income as an expense for the year in which they are incurred. The Company, based on the outcome of impairment testing explained in Note 3.e, believes that the book value of these assets does not exceed their net recoverable value. Property, plant and equipment, net of its residual value, is depreciated by distributing the cost of the different items that compose it on a straight-line basis over its estimated useful life, which is the period during which the companies expect to use such assets. Useful life estimates are periodically reviewed and, if appropriate, adjusted prospectively. The following are the main classes of property, plant and equipment with their respective estimated useful lives Classes of Property, Plant and Equipment Years of estimated useful life Buildings Plant and Equipment IT Equipment Fixtures and Fittings Motor Vehicles Other 22 – 100 3 – 65 3 – 15 5 – 21 5 – 10 2 – 33 Additionally, and for more information, there is a greater opening of the useful lives for plant and equipment class: Years of estimated useful life Generating facilities: Hydroelectric power plants Civil engineering work Electromechanical equipment Coal-fired/fuel-oil power plants Combined cycle plants Renewable energy power plants Transmission and distribution facilities: High-voltage network Low- and medium-voltage network Measuring and remote control equipment Other facilities 35-65 10-40 25-40 10-25 35 10-60 10-60 3-50 4-25 In relation to the administrative concessions held by the Group companies, following is a detail of the years to maturity period for concessions that do not have an indefinite term: Concession holder and operator Empresa Distribuidora Sur S.A.Edesur (Distribution) Hidroeléctrica El Chocón S.A.

Those requirements are essential for applying IFRIC 12 “Service Concession Arrangements,” which establishes how to record and value certain types of concessions (see Note 3.d.1 for concession arrangement within the scope of IFRIC 12). Gains or losses that arise from the sale or disposal of items of property, plant and equipment are recognized in income for the period and calculated as the difference between the sale value and the net book value. b) Investment property Investment property includes land and buildings held for the purpose to earn rentals and/or for capital appreciation. Investment property is measured initially at its cost. Subsequent to initial recognition, investment property is measured at cost less any accumulated depreciation and any accumulated impairment losses. Investment property, excluding land, is depreciated on a straight-line basis over the useful lives of the related assets. The fair value of the investment property is disclosed in Note 16. c) Goodwill Goodwill generated upon consolidation represents the difference between the acquisition cost and the Group share of the fair value of assets and liabilities, including identifiable contingent assets and liabilities of a subsidiary as of the acquisition date. Acquired assets and liabilities are temporarily valued as of the date the company takes control and reviewed within no more than a year after the acquisition date. Until the fair value of assets and liabilities is ultimately determined, the difference between the acquisition price and the book value of the acquired company is temporarily recorded as goodwill. If goodwill is finally determined to exist in the financial statements the year following the acquisition, the prior year accounts presented for comparison purposes, are modified to include the value of acquired assets and liabilities and final goodwill from the acquisition date. Goodwill generated from acquiring companies with functional currencies other than the Chilean peso is valued at the functional currency of the acquired company and converted to Chilean pesos using the exchange rate in effect as of the date of the statement of financial position. Goodwill generated before the date of transition to IFRS, January 1, 2004, is maintained at its net value recorded as of that date, while goodwill originated afterwards is valued at acquisition cost (see Notes 14 and 24.5). Goodwill is not amortized, instead, at each period end the Company estimates whether any impairment has reduced its recoverable value to an amount less than the net recorded cost and, if appropriate, immediately adjusts for impairment (see Note 3.e). Until December 31, 2009, in those cases where the Group acquired an additional ownership interest in a company already controlled and consolidated, the difference between the price of the additional ownership interest and the balance of “Equity Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 201 Financial Statements Consolidated attributable to non-controlling interests” that was derecognized as a result of the acquisition was recorded as goodwill. In those cases where the Group sold part of its interest in a controlled company that did not result in loss of control, the difference between the sale price and the balance of “Equity attributable to non-controlling interests” was recognized in net income for the year. Beginning in 2010, as part of the adoption of the amendments related to IAS 27 (Revised 2008) “Consolidated and Separate Financial Statements,” any change in ownership interests in subsidiaries that do not result in loss of control are recognized within Equity attributable to owners of parent. During 2010, there were no transactions with non-controlling interests. d) Intangible assets other than goodwill d.1) Concessions IFRIC 12 “Service Concession Arrangements” provides accounting guidance operators for public-to-private service concession arrangements. This accounting interpretation applies if: a) b) The grantor controls or regulates which services the operator should provide with the infrastructure, to whom it must provide them and at what price; and The grantor controls - through ownership, beneficial entitlement or otherwise-any significant residual interest in the infrastructure at the end of the term of the arrangement. If both of the above conditions are met, the consideration received by the Group for the infrastructure construction is recognized at its fair value, as either, an intangible asset to the extent that the Group receives the right to charge users of the public service/facility as long as those charges are conditional on usage of the facility, or as a financial asset to the extent that the Group has an unconditional contractual right to receive cash or another financial asset from the grantor or a third party. The Group recognizes the contractual obligations assumed for the infrastructure maintenance during the infrastructure’s use, or for its return to the grantor at the end of the concession agreement within the conditions specified in such concession agreement, as long as it does not relate to an activity that generates income, in accordance with the Group’s provision accounting policy. Finance expenses attributable to the concession arrangement are capitalized based on criteria established in Note 3 a) above, to the extent that the Group has a contractual right to receive an intangible asset. The median financing rate in Brazil, where the concession arrangements that require capital expenditures are located, ranges between 9.5% and 12.5% in prior periods. During 2010, we did not capitalize finance expenses. Note that the finance expenses capitalized in 2009 and 2008 were ThCh$ 1,992,733 and ThCh$ 2,648,915, respectively. Additionally, during the years ended December 31, 2010, 2009, and 2008 we capitalized employee expenses attributable to construction in progress in the amount of ThCh$ 18,128,254, ThCh$ 17,007,228 and ThCh$ 13,988,133, respectively.

Expenditures on research activities are recognized as an expense in the period in which they are incurred. In 2010, 2009 and 2008 no research and development expenses were recognized. d.3) Other intangible assets These intangible assets correspond primarily to computer software, water rights, and easements. They are initially recognized at acquisition or production cost and, subsequently, are measured at cost less accumulated amortization and impairment losses, if any. Computer softwares are amortized, on an average, in five years. Certain easements and water rights have indefinite useful lives, as such, they are not amortized. Easements and water rights in some cases have indefinite useful live, as thus, are not amortized. In others cases, they have a useful live that, depending on their own characteristics, range between 40 and 60 years, term which is used to amortize the asset. The criteria for recognizing impairment losses or, if appropriate, recoveries of impairment losses recorded in prior periods are explained in letter e) of this Note. e) Asset impairment During the period, and principally at period end, the Company evaluates whether there is any indication that an asset has been impaired. Should any such indication exist, the company estimates the recoverable amount of that asset to determine, where appropriate, the amount of impairment. In the case of identifiable assets that do not independently generate cash flows, the company estimates the recoverability of the Cash Generating Unit to which the asset belongs, which is understood to be the smallest identifiable group of assets that generates independent cash inflows. Notwithstanding the preceding paragraph, in the case of Cash Generating Units to which goodwill or intangible assets with an indefinite useful life have been allocated, a recoverability analysis is performed routinely at each period end. The recoverable amount is the greater between the fair value less the cost needed to sell and the value in use, which is defined as the present value of the estimated future cash flows. In order to calculate the recoverable value of property, plant and equipment, goodwill and intangible assets, value in use criteria is used by the Group in practically all cases. To estimate the value in use, the Group prepares future cash flow projections, before tax, based on the most recently available budgets. These budgets incorporate management’s best estimates of revenue and costs of Cash Generating Units using sector projections, past experience and future expectations. In general, these projections cover the next ten years, estimating cash flows for Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 203 Financial Statements Consolidated subsequent years by applying reasonable growth rates between 3.3% and 6.7% that, in no case, are increasing nor exceed the average long-term growth rates for the particular sector and country. These cash flows are discounted at a given pre-tax rate in order to calculate their present value. This rate reflects the cost of capital of the business and the geographical area in which the business is carried on. In order to calculate the discount rate, the current time value of money and the risk premiums generally used by analysts for the business and the geographical area are taken into account. The discount rates, before tax, expressed in nominal terms and applied in 2010 and 2009 are the following: Country Chile Currency Chilean peso Argentina Argentine peso Brazil Peru Brazilian reais Peruvian sol Colombia Colombian peso 2010 2009 Minimum Maximum Minimum Maximum 7.5% 15.0% 9.6% 7.9% 9.6% 8.8% 16.9% 10.8% 8.1% 9.8% 9.2% 9.5% 19.5% 11.3% 9.1% 11.5% If the recoverable amount is less than the net carrying amount of the asset, the corresponding provision for impairment loss is recorded for the difference, and charged to “Reversal of impairment loss (impairment loss) recognized in profit or loss” in the consolidated statement of comprehensive income. Impairment losses recognized for an asset in prior periods are reversed when its estimated recoverable amount changes, increasing the asset’s value with a credit to earnings, limited to the asset’s carrying amount if no adjustment had occurred. In the case of goodwill, adjustments that would have been made are not reversible. The following procedure is used to determine the need to adjust financial assets for impairment: • In the case of commercial assets, the Group has a policy to record impairment through an allowance account determined based on the age of past-due balances, which is generally applied except in those cases where a specific collectability analysis is recommended, such as the case for receivables from public-related companies. In the case of receivables of a financial nature, impairment is determined on case-by-case basis. As of the date of issuance of these consolidated financial statements, the Company had no significant past due non commercial financial assets. • f) Leases Leases that transfer to the lessee substantially all of the risks and rewards incidental to ownership are classified as finance leases. All other leases are classified as operating leases. Finance leases in which the Group acts as a lessee are recognized when the agreement begins. At that point, the Group records an asset based on the nature of the lease and a liability for the same amount, equal to the lower of the fair value of the leased asset or the present value of the minimum lease payments. Subsequently, the minimum lease payments are divided between finance expense and principal reduction. The finance expense is recorded in the income statement and distributed over the lease term, so as to obtain a constant interest rate for each period over the balance of the debt pending amortization. The asset is amortized in the same terms as other similar depreciable assets, as long as there is reasonable certainty that the lessee will acquire Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 204 Enersis 2010 Annual Report ownership of the asset at the end of the lease. If no such certainty exists, the asset will be amortized over the lesser term between the useful life of the asset and the term of the lease. Operating lease payments are expensed on a straight-line basis over the term of the lease unless another type of systematic basis of distribution is deemed more representative. g) Financial instruments Financial instruments are contracts that give rise to both a financial asset in one company and a financial liability or equity instrument in another company. g.1) Financial assets other than derivatives The Group classifies its financial assets other than derivatives, whether permanent or temporary, and excluding equity method investments (see Note 12) and investments held for sale (see Note 11), into four categories: • Trade and other current receivables and Accounts receivable from related companies: These are recorded at amortized cost, which corresponds to initial fair value less principal repayments made, plus accrued and uncharged interest, calculated using the effective interest method. The effective interest method is used to calculate the amortized cost of a financial asset or liability (or group of financial assets or financial liabilities) and is charged to finance income or cost over the relevant period. The effective interest rate is the discount rate that matches the estimated cash flows to be received or paid over the expected life of the financial instrument (or, when appropriate, over a shorter period) to the net carrying amount of the financial asset or financial liability. • • • Held-to-maturity investments: Investments that Enersis intends to hold and is capable of holding until their maturity are accounted for at amortized cost as defined in the preceding paragraph. Financial assets at fair value with changes in net income: This includes the trading portfolio and those financial assets that have been designated as such upon initial recognition and that are managed and evaluated using fair value criteria. They are valued in the consolidated statement of financial position at fair value, with changes in value recorded directly in income when they occur. Available-for-sale financial assets: These are financial assets specifically designated as available for sale or that do not fit within any of the three preceding categories and consist almost entirely of financial investments in equity instruments (see Note 6). These investments are recorded in the consolidated statement of financial position at fair value when it can be reliably determined. Changes in fair value, net of taxes, are recorded with a charge or credit to an equity reserve known as “Gains (losses) on remeasuring available-for-sale financial assets” until the investment is disposed of, at which time the amount accumulated in this account for that investment is fully charged to the comprehensive income statement. Should the fair value be less than the acquisition cost and if there is objective evidence that the asset has been more than temporarily impaired, the difference is recorded directly in the comprehensive income statement.

When this occurs, those interests are valued at acquisition cost or a lesser amount if evidence of impairment exists. Purchases and sales of financial assets are accounted for using their trade date. g.2) Cash and cash equivalents This account within the statement of consolidated financial position includes cash and in banks, time deposits and other highly liquid short-term investments readily convertible to cash and which are subject to insignificant risk of changes in value. g.3) Financial liabilities other than derivatives Financial liabilities are generally recorded based on cash received, net of any costs incurred in the transaction. In subsequent periods, these obligations are valued at their amortized cost, using the effective interest rate method (see Note 3.g.1). In the particular case that a liability is the underlying item of a fair value hedge derivative, as an exception, such liability will be valued at its fair value for the portion of the hedged risk. In order to calculate the fair value of debt, both in the cases when it is recorded in the statement of financial position and for fair value disclosure purposes as seen in Note 20, debt has been divided into fixed interest rate debt (hereinafter “fixed-rate debt”) and variable interest rate debt (hereinafter “floating-rate debt”). Fixed-rate debt is that on which fixed-interest coupons established at the beginning of the transaction are paid explicitly or implicitly over its term. Floating-rate debt is that issued at a floating interest rate, i.e., each coupon is established at the beginning of each period based on the reference interest rate. All debt has been valued by discounting expected future cash flows with a market-interest rate curve based on the payment’s currency. g.4) Derivative financial instruments and hedge accounting Derivatives held by the Group correspond primarily to transactions entered into to hedge interest and/or exchange rate risk, intended to eliminate or significantly reduce these risks in the underlying transactions being hedged. Derivatives are recorded at fair value as of the date of the statement of financial position as follows; if their fair value is positive, they are recorded within “Other financial assets”; and if their fair value is negative, they are recorded within “Other financial liabilities.” Changes in fair value are recorded directly in income except when the derivative has been designated for accounting purposes as a hedge instrument and all of the conditions established under IFRS for applying hedge accounting are met, including that the hedge is highly effective. In this case, changes are recorded as follows: • • Fair value hedges: The underlying portion for which the risk is being hedged is valued at its fair value as is the hedge instrument, recording any changes in the value of both in the comprehensive income statement by netting the effects in the same comprehensive income statement account. Cash flow hedges: Changes in the fair value of the effective portion of derivatives are recorded in an equity reserve known as “Reserve of cash flow hedges.” The cumulative loss or gain in this account is transferred to the comprehensive income statement to the extent that the underlying item impacts the comprehensive income statement because of the hedged risk, netting the effect in the same comprehensive income statement account. Gains or losses from the ineffective portion of the hedge are recorded directly in the comprehensive income statement.

The Company does not apply hedge accounting to its investments abroad. As a general rule, long-term commodity purchase or sale agreements are recorded in the consolidated statement of financial position at their fair value as of period end, recording any differences in value directly in income, except when all of the following conditions are met: • • The sole purpose of the agreement is for the own use. The Group’s futures projections justify the existence of these agreements with the purpose of own use. • Past experience with agreements shows that they have been utilized for own use, except in certain isolated cases in which they had to be used for exceptional reasons or reasons associated with logistical management issues outside the control and projection of the Group. • The agreement does not stipulate settlement by differences and the parties do not make it a practice to settle similar contracts by differences in the past. The long-term commodity purchase or sale agreements maintained by the Group, which are mainly for electricity, fuel and other supplies, meet the conditions described above. Thus, the purpose of fuel purchase agreements is to be used to generate electricity, the electricity purchase contracts are used to materialize sales to end- customers and the electricity sale contracts are used to sell the company’s own product. The Company also evaluates the existence of embedded derivatives in contracts or financial instruments to determine if their characteristics and risk are closely related to the principal contract as long as the set is not being accounted for at fair value. If they are not closely related, they are recorded separately and changes in value are accounted for directly in the comprehensive income statement. g.5) Fair value measurement and classification of financial instruments The fair value of the various derivative financial instruments is calculated as follows: • • For derivatives traded on a formal market, by its quoted price as of year end. Enersis and subsidiaries value derivatives not traded on formal markets, using discounted expected cash flows and generally accepted options valuation models, based on current and future market conditions as of year-end. Based on the described procedures, the Group classifies financial instruments in the different levels: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and Level 3: Inputs for assets or liabilities that are not based on observable market data (unobservable inputs). g.6) Derecognition of financial assets Financial assets are derecognized when: • The contractual rights to receive the financial asset’s cash flows expire or have been transferred, or if the contractual rights are retained, the Group has assumed a contractual obligation to pay the financial asset’s cash flows to one or more receiver.

Where the Group retains substantially all the inherent risks and rewards of ownership of the tranferred asset, it continues recognizing the transferred asset in its entirety and recognizes a financial liability for the consideration received. Transactions costs are recognized in profit and loss by using the effective interest method (see Note 3.g.1.) h) Investments accounted for using equity method Investments in associates in which the Group has significant influence are recorded using the equity method. In general, significant influence is assumed in cases in which the Group has more than 20% interest. The equity method consists of recording the investment in the statement of financial position based on the share of its equity that the Group’s interest represents in its capital, adjusted for, if appropriate, the effect of transactions with subsidiaries plus any goodwill generated in acquiring the company. If the resulting amount were negative, zero is recorded for that investment in the statement of financial position, unless there is a commitment from the Group to support the company’s negative equity situation, in which case a provision is recorded. Dividends received from these companies are deducted from the value of the investment and any profit or loss obtained from them to which the Group is entitled based on its interest is recorded within “Share of profit (loss) of associates accounted for using equity method.” Appendix No. 3 “Enersis Group Associated Companies,” included in these consolidated financial statements, provides information about Enersis’s relation with each of its associates. i) Inventories Inventories are valued at the lesser of their weighted average acquisition price or net realizable value. j) Non-current assets held for sale and discontinued operations The Group classifies as “Non-current assets held for sale,” property, plant and equipment; intangible assets; investments accounted for using the equity method; and disposals groups (group of assets to be disposed of and liabilities directly associated with those assets), if as of the date of the consolidated financial statements, the Group has taken active measures for their sale and estimates that such sale is highly probable These held-for-sale assets or disposal groups are measured at the lower of their carrying amount and fair value less costs to sell. Depreciation and amortization on these assets cease when they meet the criteria to be classified as held for sale. Non-current assets held for sale and the components of the disposal groups classified as held for sale are presented in the accompanying consolidated statement of financial position as a single line item within assets called “Non-current assets or disposal groups classified as held for sale” and the respective liabilities are presented as a single line item within liabilities called “Liabilities included in disposal groups classified as held for sale.” Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 208 Enersis 2010 Annual Report The Group classifies as “Discontinued operations” those which represent separate major lines of business or are part of a single coordinated plan to dispose of a separate major line of business that either has been disposed of, or are classified as held for sale. Additionally, the Group classifies as “Discontinued operations” subsidiaries that have been acquired exclusively for resale. The components of profit or loss after taxes from discontinued operations are presented as a single line item in the consolidated comprehensive income statement as “Net income from discontinued operations.” k) Treasury shares Treasury shares are deducted from equity in the consolidated statement of financial position and valued at acquisition cost. The gains and losses from the disposal of treasury shares are recorded under the heading Total equity: treasury shares. As of December 31, 2010, there are no treasury shares and no transactions with equity share were made during 2010, 2009 and 2008. l) Provisions Obligations existing as of the date of the consolidated financial statements resulting from past events which may negatively impact the Group’s equity and whose amount and timing of payment are uncertain, are recorded as provisions in the consolidated statement of financial position at the present value of the most likely amount that it is believed that the Group will have to disburse to settle the obligation. Provisions are quantified using the best information available as of the date of issuance of the consolidated financial statements regarding the consequences of the event causing the provision and are re-estimated at each subsequent accounting close. l.1) Provisions for post-employment benefit and similar obligations Some of the Group’s subsidiaries have pension and similar obligations to their employees. Such obligations, which combine defined benefits and defined contributions, are basically formalized through pension plans, except for certain non- monetary benefits, mainly electricity supply obligations, which, due to their nature, have not been externalized, and are covered by the related in-house provisions. For defined benefit plans, the cost of providing benefits is determined using the Projected Unit Credit Method, with actuarial valuations being carried out at the end of each reporting period. Past service costs relating to changes in benefits are recognized immediately to the extent that the benefits are already vested, and otherwise are amortized on a straight-line basis over the average period until the benefits become vested. The defined benefit plan obligations in the statement of financial position represent the present value of the defined benefit obligations a adjusted for unrecognized actuarial gains and losses and unrecognized past service costs, and reduced by the fair value of plan assets. For each of the plans, any positive difference between the actuarial liability for past services and the plan assets is recognized under line item “Provisions for employee benefits” within current and non-current liabilities in the consolidated statement of financial position and any negative difference is recognized under line item “Other financial assets” within non-current assets in the consolidated statement of financial position, provided that such negative difference is recoverable by the Group, usually through a reduction in future contributions and taking into consideration the limit Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 209 Financial Statements Consolidated established in IFRIC 14, “IAS 19 The limit on a defined benefit asset, minimum funding requirements and their interaction.” Contributions to defined contribution benefit plans are recognized as an expense in the consolidated statement of comprehensive income when the employees have rendered their services. Actuarial gains and losses arising in the measurement of both the plan liabilities and the plan assets, including the limit in IFRIC 14, are recognized directly under “Equity — Retained earnings.” m) Conversion of balances in foreign currency Transactions carried out by each company in a currency other than its functional currency are recorded using the exchange rates in effect as of the date of each transaction. During the year, any differences that arise between the exchange rate recorded in accounting and the rate prevailing as of the date of collection or payment are recorded as “Foreign currency exchange differences” in the comprehensive income statement. Likewise, as of each year end, balances receivable or payable in a currency other than each company’s functional currency are converted using the period-end exchange rate. Any valuation differences are recorded as “Foreign currency exchange differences” in the comprehensive income statement. The Group has established a policy to hedge the portion of its revenue that is directly linked to the US dollar by obtaining financing in this currency. Exchange differences related to this debt, as they are cash flow hedge transactions, are charged, net of taxes, to a reserve account in equity and recorded in income during the period in which the hedged cash flows are realized. This term has been estimated at ten years. n) Current/Non-Current Classification In the accompanying consolidated statement of financial position, assets and liabilities expected to be recovered or settled within twelve months are presented as current items and those assets and liabilities expected to be recovered or settled in more than twelve months are presented as non-current items. Should the Company have any obligations that mature in less than twelve months but can be refinanced over the long term at the Company’s discretion, through unconditionally available credit agreements with long-term maturities, such obligations may be classified as long-term liabilities. o) Income tax Income taxes for the year are determined as the sum of current taxes from the Group numerous subsidiaries and result from applying the tax rate to the taxable base for the year, after allowable deductions have been made, plus any changes in deferred tax assets and liabilities and tax credits, both for tax losses and deductions. Differences between the book value and tax basis of assets and liabilities generate deferred tax asset and liability balances, which are calculated using tax rates expected to be in effect when the assets and liabilities are realized. Current taxes and changes in deferred tax assets and liabilities not arising from business combinations are recorded in income or in equity in the statement of financial position, based on where the gains or losses originating them were recorded.

Deferred tax assets and tax credits are recognized only when it is likely that there will be future tax gains sufficient enough to recover deductions for temporary differences and make use of tax losses. Deferred tax liabilities are recognized for all temporary differences, except those derived from the initial recognition of goodwill and those that arose from valuing investments in subsidiaries, associates and jointly-controlled companies in which the Group can control their reversal and where it is likely that they will not be reversed in the foreseeable future. Any deductions that can be applied at a given moment to current tax liabilities are credited to earnings within the income tax account, except when doubts exist about their tax realization, in which case they are not recognized until they are effectively realized, or when they correspond to specific tax incentives, in which case they are recorded as grants. At each accounting period close, the Company reviews the deferred taxes it has recorded, both assets and liabilities, in order to ensure they remain current and otherwise make any necessary corrections based on the results of this analysis. p) Revenue and expense recognition Revenue and expense are recognized on an accrual basis. Revenue is recognized when the gross inflow of economic benefits arising in the course of the Group’s ordinary activities in the year occurs, provided that this inflow of economic benefits results in an increase in total equity that is not related to contributions from equity participants and that these benefits can be measured reliably. Revenue is measured at the fair value of the consideration received or receivable arising there from. Revenue associated with the rendering of services is only recognized if it can be estimated reliably, by reference to the stage of completion of the transaction at the date of the statement of financial position. The Group excludes from the revenue figure gross inflows of economic benefits received by it when it acts as an agent or commission agent on behalf of third parties, and only recognizes as revenue economic benefits received for its own account. When goods or services are exchanged or swapped for goods or services which are of a similar nature, the exchange is not regarded as a transaction which generates revenue. The Group records for the net amount non-financial asset purchase or sale contracts settled for the net amount of cash or through some other financial instruments. Contracts entered into and maintained for the purpose of receiving or delivering these non-financial assets are recognized on the basis of the contractual terms of the purchase, sale or usage requirements expected by the entity. Interest income (expense) is recognized by reference to the effective interest rate applicable to the principal outstanding over the related repayment period. q) Earnings per share Basic earnings per share are calculated by dividing net income attributable to owners of the Parent (the numerator) by the weighted average number of ordinary shares outstanding (the denominator) during the year, excluding, if any, the average number of shares of the Parent held by the Group.

As it is practically impossible to achieve a unanimous agreement given Enersis’s highly fragmented share capital, as of the end of each year the amount of the dividend obligation to its shareholders, net of interim dividends approved during the year, is determined and accounted for in “Trade and other current payables” or “Accounts payable to related companies,” as appropriate, and charged to Equity. Interim and final dividends are deducted from equity as soon as they are approved by the competent body, which in the first case is normally the Company’s Board of Directors and in the second case is the Ordinary Shareholders’ Meeting. s) Cash flow statement The cash flow statement reflects the changes in cash that took place during the year in relation to both continuing and discontinued operations, calculated using the indirect method. The following terms are used in the consolidated cash flow statements: • • • • Cash flows: inflows and outflows of cash or cash equivalents, which are defined as highly-liquid investments maturing in less than three months with a low risk of changes in value. Operating activities are the principal revenue-producing activities of the Group and other activities that are not investing or financing activities. Investing activities are the acquisition and disposal of long-term assets and other investments not included in cash and cash equivalents. Financing activities are activities that result in changes in the size and composition of the contributed equity and borrowings of the Group. Note 4. Sector Regulation and Electricity System Operations There are different regulations in the Latin American countries in which the Group operates. We discuss below the main characteristics of each business. 4.1. Generation: Chile In Chile the electricity sector is regulated by the General Law of Electrical Services (Chilean Electricity Law), also known as DFL No. 1 of 1982, of the Ministry of Mining —whose compiled and coordinated text was established by DFL No. 4 issued in 2006 by the Ministry of Economy (“Electricity Law”)— as well as by an associated Regulation (D.S. No. 327 issued in 1998).

The Ministry of Energy also includes an Agency for Energy Efficiency and a Center for Renewable Energy. The Chilean Electricity Law has established an “Experts Panel” whose main task is to resolve potential discrepancies among all participants in the electricity market such as electricity companies, system operator, regulator, etc. The Chilean electrical sector is divided into four interconnected electrical systems: the Sistema Interconectado Central (SIC), the Sistema Interconectado del Norte Grande ( “SING”), and two separate medium-size systems located in southern Chile, one in Aysén and the other in Magallanes. The SIC is the main electrical system covering 2,400 km, connecting Taltal in the northern part with Quellon, located on the island of Chiloe, in the southern part of the country . The SING covers the northern part of the country, from Arica down to Coloso, covering approximately 700 km. The electricity industry is divided into three business segments: generation, transmission, and distribution, operating in an interconnected and coordinated manner, and whose main purpose is to supply electrical energy to the market at minimum cost while maintaining quality and safety service standards required by the electrical regulations. Given their characteristics, Transmission and Distribution businesses are natural monopolies, and are segments regulated as such by the electricity low, requiring free access to networks and establishing regulated tariffs. Under the Chilean Electricity Law, companies engaged in generation and transmission on an interconnected electrical system must coordinate their operations in a centralized manner through an operating agent, the Centro de Despacho Económico de Carga (“CDEC”), in order to operate the system at minimum cost while maintaining service safety. For this reason, the CDEC plans and operates the system, including the calculation of the so called “marginal cost,” which is the price at which energy transfers among generators performed through the CDEC are valued. Therefore, a company’s decision to generate electricity is subject to CDEC’s operation plan. On the other hand, a company is free to decide whether to sell its energy to regulated or unregulated customers. Any surplus or deficit between sales to customers and energy supply, is sold to, or purchased from, other generators at the spot market price. An electricity generator company may have the following types of clients: (i) Regulated customers: Corresponds to those residential and commercial consumers and small and medium size businesses with a connected maximum capacity equal to or less than, 2,000 KW that are located in the concession area of a distribution company. Until 2009, the transfer prices between generators and distribution companies were capped at a maximum value called node price, which is regulated by the Ministry of Economy. Node prices are determined every six months, in April and October, based on a report prepared by the CNE that takes into account projections of expected marginal costs in the system over the next 48 months for the SIC and 24 months for the SING. Beginning on 2010, the transfer prices between generators and distributors will be established in regulated bidding processes carried out by these companies.

These consumers can freely negotiate prices for electrical supply with generators and/or distributors. Customers with capacity between 500 and 2,000 KW have the option to contract energy at prices agreed upon with their suppliers or be subject to regulated prices, with a minimum stay of at least four years under each price regime. (iii) Spot market: Represents the energy and capacity transactions among generators that result from the CDEC coordination to achieve the economical operation of the system, where the excess (surpluses/deficits) between the energy supply and the energy to comply with business commitments is transferred through sale (purchase) to (from) other generators in the CDEC. In the case of energy, transfers are valued at the marginal cost; in the case of capacity, at the node prices set every semester by the regulators. In Chile, the capacity that must be paid back to each generator depends on an annual calculation performed by the CDEC, which yields the final capacity of each power plant, that is independent from the dispatched capacity. Beginning in 2010 with the enactment of Law 20,018 distribution companies must have permanently available supply to cover their entire demand projected for a period of three years; as such they have to undertake long-term public bids. Regarding renewable energy, in April of 2008 Law 20,257 was enacted, which encourages the use of Non-Conventional Renewable Energies (“ERNC”). This law requires generators to provide at least 5% of their energy from renewable sources between years 2010 and 2014. This requirement progressively increases by 0.5% from years 2015 until 2024, where a 10% renewable energy requirement would be reached. Rest of Latin America In the other Latin American countries where the Group operates, different regulations are enforced. In general, regulations in Brazil, Argentina, Peru and Colombia allow participation of private capital in the electricity sector, uphold free competition in electricity generation, and define criteria to avoid certain levels of economic concentration and/or market practices that may cause a decline in this activity. Unlike Chile, state-owned companies participate in the electricity sector together with private companies in the electricity generation, transmission and distribution activities The participation of companies in different activities (generation, distribution, and commercial), is allowed, as long as these activities are properly separated, both from an accounting and corporate point of view. Nevertheless, the transmission sector is where the strictest restrictions are usually imposed, mainly due to its nature and the need to assure adequate access to all players. In regards to the main characteristics of the electricity generation business, one can indicate that in general these are open markets in which private players are free to make their own investment decisions. The exceptions are Brazil, a country which, based on the contractual needs of the distribution companies, the Ministry of Energy actively participates in the electricity system’s expansion by establishing capacity quotas by technology (separate bids for thermal, hydraulic, or renewable energies) or participates directly by organizing public bids for specific projects; and Argentina where despite the government has promoted initiatives to encourage electricity investments, such as “Energia Plus,” the increase in installed capacity has not been as expected. On November 25, 2010, the Ministry of Energy of Argentina and the participants in the electricity generation market signed an agreement that, among other aspects, seeks to increase new generation project developments financed with funds that make up part of the outstanding debt that the Argentine government has with electricity companies.

Except for Colombia, where charge dispatched is based on prices offered by the players, in the other countries charge dispatched is centralized, based on variable production costs that seeks to assure the fulfillment of the demand at a minimum cost for the system. From that dispatch, the marginal cost, which defines the price for spot transactions, is determined. Nevertheless, Argentina and Peru currently intervene to some extent in the formation of price in these marginal generation markets. This occurs in Argentina after the 2002 crisis, and in Peru as a result of a recent Emergency Law enacted in 2008 that defines a marginal idealized cost, considering that no actual restrictions exist on the transportation system for gas and electricity. In Colombia, Brazil, Peru and Argentina generation players are able to sell energy through contracts in the regulated market or in the unregulated market, and trade their surplus/deficit on the spot market. The unregulated market is focused on the segment of large users, although the limits that define such a status vary in each market. The principal differences among the markets involve the way of regulating the sale of energy among generators and distributors and how regulated prices are established for the determination of the tariffs charged to end users. Initially, Argentine law contemplated that the selling price charged by generators to distributors would have to be obtained from a centralized calculation of the average spot price expected for the next six months. However, after the 2002 crisis, Argentine authorities have established the price arbitrarily, forcing intervention in the marginal system and provoking a mismatch between actual generation costs and payment of the demand through distributors. Additionally, energy that can be sold by generators is limited to the demand that each generator had sold via energy contracts during the May - June 2005 period. In Brazil, the regulated purchase price used in the determination of tariffs to end users is based on average prices of open bids, and there are separate bidding processes for existing and new energy. Bidding processes for new energy contemplate long- term generation contracts in which new generation projects must cover the growth of demand foreseen by distributors. The open bids for existing energy consider shorter contractual terms and seek to cover the distributors’ contractual needs arising from the expiry of prior contracts. Each bidding process is coordinated centrally. Authorities define maximum prices and, as a result, contracts are signed where all distributors participating in the process buy pro rata from each offering generator. In Colombia distributors are free to decide their supply, being able to define the conditions of public bidding processes where they acquire energy for the regulated market and are able to buy energy in the spot market. Prices paid by end users reflect an average of the purchase price. Since 2004, the CREG (the Colombian energy and gas regulation commission) is working in a proposal to modify the energy contracting system in the Colombian market. Under the proposal, the existing contracting system will be modified into an electronic contract system. This mechanism will replace the current bidding process for energy auctions with standardized commercial conditions, where contractual demand will be treated as one aggregate demand. In Peru, similar to Chile, distributors are obligated to enter into contracts, and the legislation was amended so that the public bids for energy would be based on distributor requirements. Currently, there are only a few contracts between generators and distributors that are in force at “bar price,” which is defined based on a centralized calculation. Nevertheless, since 2007 contracts are based on public bids. Authorities approve bidding bases and define the maximum price for each bid.

In practical terms, there are no incentives or obligations similar to those in Chile that would push these renewable energy technologies to be competitive on a greater scale. Authorities are responsible for promoting specific bidding processes benefiting from special conditions in order to make these projects viable. 4.2 Distribution: In the five countries where the Group operates, selling prices charged to clients are based on the purchase price paid to generators plus a component associated with the value added in distribution. Regulators set this value periodically through reviews of distribution tariffs. As a result, distribution is an essentially regulated activity. Chile In Chile, the distribution value added (“VAD”) is established every four years. For this, the local regulator, (i.e. the CNE) classifies companies in accordance with typical areas that group companies with similar distribution costs. A distribution company’s return on investment is dependent on the company’s performance in relation to model company standards defined by the regulator. In April 2009, the regulator published tariff formulas which are effective for the period November 2008 through November 2012. Rest of Latin America In Peru, the VAD is calculated every 4 years, also using a model company method based on a typical area. In October 2009 the tariffs for the 2009-2013 period were published In Brazil there are three types of tariff adjustments: (i) Ordinary Tariff Reviews (“RTO”) which are conducted periodically in accordance with the provisions in the concession contracts (in Coelce every 4 years and in Ampla every 5 years). (ii) Annual adjustment (IRT); and (iii) Extraordinary Reviews. The latest RTO for Ampla is applicable for the 2009-2014 periods and for Coelce for the 2007-2011 periods. The most recent annual adjustments made by Aneel were in March 2010 for Ampla and April 2010 for Coelce. In Colombia, the CREG established in 2008 a new methodology for calculating the rate of return applicable to the compensation of the distribution, and a new methodology for establishing the charges for regional transmission and local distribution systems use. In October 2009 the CREG published the distribution charges for Codensa for the period 2009-2013. In Argentina, tariffs were frozen after the country’s debt default in 2001. Edesur’s tariff restructuring started in 2007 with the enforcement of the “acta de acuerdo.” In the current year, tariff adjustments (positive impact in the VAD) and inflation readjustments (via the cost monitoring mechanism, “MMC”) have been made. In July 2008 increases were authorized for clients with consumption in excess of 650kWh quarterly, and in October 2008 the government approved an increase for consumption in excess of 1,000kWh per month; this last increase is a pass-through to the generators and was suspended between June and September 2010 but restarted in October 2010. The RTI (comprehensive tariff review) related to Edesur’s concession contract is still pending.

The supply limitations imposed on the unregulated market are as follows: Country Argentina Brazil Chile Colombia Peru kW Threshold > 30 kW > 3,000 kW > 500 kW > 100 kW o 55 MWh-month (**) > 200 kW (*) (*) In April 2009, Peru established that clients between 200 and 2,500 kW could choose between regulated or unregulated market. (**) Colombia wants to decrease this threshold to 65kW or 35 MWh per month starting in January 2011. However, this decision has not been ratified. • Limits on integration and concentration In general, current legislation defends free competition and defines criteria to avoid certain levels of economic concentration and/or market practices that would lead to a deterioration of the market. In principle, the regulators allow the participation of companies in different activities (e.g. generation, distribution, and commercialization) as long as there is an adequate separation of each activity, for both accounting and company purposes. Nevertheless, most of the restrictions imposed involve the transport sector mainly because of its nature and the need to guarantee adequate access to all agents. In Argentina and Colombia there are specific restrictions if generation or distribution companies want to become majority shareholders in transportation companies. Additionally, in Colombia, companies that were created subsequent to 1994 cannot be vertically integrated. Furthermore, generation companies cannot participate in a distribution company if the participation rate is greater than 25% and vice versa. Moreover, companies in Peru need a permit from the local authority if they have a interest stake greater than 5% in a business and want to participate in another business. Regarding concentration in a specific sector, in Argentina and Chile, there are no specific limits that affect the vertical or horizontal integration of a company. On the other hand, in Peru, integrations are subject to authorization if such integration is 5% vertical and 15% horizontal. In Colombia, for the generation and commercialization sectors, companies cannot have a market participation that exceeds 25%. Finally in Brazil, since 2007 there have been no restrictions to generation integration. As for distribution, there are concentration limits, both on a national and electric subsystem level. On a national level, the authorities allow a 20% concentration in both segments. As for the electric subsystem, the limit is 35% of the North and Northeast subsystems and 25% of the South, Southeast, and Midwest subsystems. With regard to consolidations and mergers between agents of the same segment, current regulation requires authorization from the local regulator. • Access to the Network. In the countries where the Group operates, the right of access and toll or access price is regulated by the local authority. In Peru, the toll setting process that recognizes investments in Secondary and Complementary Transmission Systems for the period July 2006 through April 2013, and which are effective starting November 1, 2009 concluded back in 2009. In Chile, during 2010, local authorities developed part of the tariff process for the determination of the Subtransmission System Annual Value for the period 2011 through 2014.

Non-Current Assets and Disposal Groups Held for Sale During the fourth quarter of 2009, the Board of Directors of Enersis authorized the sale of the subsidiaries Compañía Americana de Multiservicios (“CAM”) and Synapsis Soluciones y Servicios IT Ltda. (“Synapsis”) as they were considered “non-core” businesses. The sale process included at first an internal verification of the market and the hiring of a financial advisor to provide assistance in the sale process, so that, once offers were received, they were submitted to the Board so that it can make the final decision about the sale and its specific conditions. The potential sale of CAM was considered to be highly probable as of the end of 2009. As for Synapsis, such consideration was taken into account as of the September 2010. After those dates, the Company applied IFRS 5 Non-current Assets Held for Sale and Discontinued Operations (“IFRS 5”) to account for those transactions. CAM and Synapsis provide services in the five countries where Enersis operates in Latin America, i.e. Chile, Argentina, Brazil, Colombia and Peru. CAM is present with its products and services in the complete electric cycle such as provision, materials logistics, construction and startup of electric projects, certification of equipment, and measurement of final consumption. On the other hand, Synapsis is a company that provides information technolog services. It specializes in defining strategies companies can use and software selection that satisfies current business needs. Synapsis also designs the infrastructure of the services that will be provided and the methodology that should be used among other services.

The CAM offer was presented by Graña y Montero S.A.A, a Peruvian company that offered US$ 20 million, which will be paid in cash, subjet to price adjustments at the closing of the sale transaction. As for Synapsis, Riverwood Capital L.P., a company domiciled in the United States of America, presented a US$ 52 million offer to purchase Synapsis, that will be paid upon closing of the sales transaction. The Company foresees that both operations will be finalized during the first months of 2011.

a) Main Investments Material investments in the electricity generation business include developments in the program to create new capacity. In Chile, the construction of the Bocamina II Coal-fired Thermal Power Plant with capacity of 370 MW stands out among other projects. The project Central Térmica Quintero, consisting primarily of an open-cycle plant that operates both with LNG (liquid natural gas) and with diesel with capacity of 257 MW, was completed and started operations on September 2009. The Canela II Wind Farm Expansion project with 40 wind generators with 60 MW capacity has been finalized and put in operation on December 2009, reinforcing Endesa Chile’s commitment witer the environment by developing non-conventional renewable energies (NCREs). In Colombia, the Central Hidráulica El Quimbo, a hydroelectric dam with 400W of installed capacity and average anual generation around 2,216 GWH, is currently under construction. In Peru, the Santa Rosa Open Cycle Thermoelectric Power Plant with a capacity of 189 MW was completed and placed in service in September 2009. This plant is currently operating using natural gas from Camisea. 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries pages control previously next 233 Financial Statements Consolidated b) Finance leases As of December 31, 2010 and 2009, property, plant and equipment includes ThCh$ 129,749,447 and ThCh$ 137,586,941, respectively, in leased assets classified as finance leases.

Edegel S.A.: lease agreements to finance the project of converting the Ventanilla thermoelectrical plant to a combined cycle plant. The agreements were entered between Edegel S.A. and the financial institutions Banco de Crédito del Perú and BBVA - Banco Continental. These agreements have an 8-year maturity and bear interest at an annual rate of Libor + 2.0% and Libor +3.0% as of December 31, 2010 and 2009, respectively. c) Operating leases As of December 31, 2010, 2009 and 2008 total payments recognized as expense from operating leases totaled ThCh$ 16,980,825, ThCh$ 19,969,187 and ThCh$ 15,312,905, respectively.

The Company and its foreign subsidiaries have insurance policies for risk, earthquake, machinery breakdown and damages for business interruption with a US$ 300 million limit in the case of generating companies and a US$ 30 million limit for distribution companies, including business interruption coverage, The premiums associated with these policies are presented under line item “Prepayments” within assets, iv) GasAtacama, in which Endesa Chile has a 50% interest consolidated using the proportional integration method, has, among other assets, a combined- cycle electricity generation plant in northern Chile. As importing natural gas from neighboring countries was not possible, GasAtacama has been forced to generate electricity using alternative fuels, the cost of which significantly increased during the last months of 2007 due to increases in oil prices. As a result, the company filed lawsuits for early termination of a contract with distributor Emel. On January 25, 2008, a ruling was issued in arbitration proceedings on this matter to deny early termination. This situation significantly reduced the recoverable value of the aforementioned plant and, therefore, as of December 31, 2007, an impairment provision of US$ 110 million was recorded. The current situation regarding long-lived assets, mostly plants and infrastructure constructed with the purpose of providing energy resources for the SIC system from year 1998, has changed, principally due to the installation of new thermal plants in the SIC, the arrival of LNG, and the estimated development of new projects. This situation has created an environment of excess supply for future years resulting in the expectation that some of these assets will not be used. Accordingly, at December 31, 2009 the Company has recorded an impairment provision for these assets for ThCh$ 43,999,600, v) vi) As a result of the February 27, 2010 earthquake in Chile, some of our plant and equipment were partially or totally impaired. The impact on our total assets, however, is minor as the only facilities that suffered some damage in infrastructure were the Bocamina and Bocamina II plants, the latter under construction, as well as a few other assets from our distribution business. Due to the aforementioned impairments, we have written down ThCh$ 395,153 in assets. Additionally, the Group had to incur expenditures related to repairment and capital improvements totaling ThCh$ 13,043,744, primarily in the Bocamina plant. All of the disbursements incurred are covered by insurance, which contain a US$ 2.5 million policy deductible. The Group has the necessary insurance coverage for these types of exceptional claims, which provide coverage for material damage, as well as business interruption. See Note 25 for additional information. vii) Companhia De Interconexão Energética (‘CIEN’) sells electricity in Argentina and Brazil.

Given the strategic importance of the Company’s assets in the relations between Brazil and Argentina, the Brazilian government has been presented with a new business plan model changing its selling activity to an electricity transmission activity with payment of a fixed compensation, which is in the process of being approved. This new plan involves integrating its transmission lines with the Brazilian transmission grid operated by the Brazilian Government. In prior periods, the Argentinean and Uruguayan governments, formalized toll payments with the Company to transport energy between the two countries. Management considers that this situation further emphasizes the importance of the application made to the Brazilian Government to approve the new business plan and considers that it will probably be approved. In addition, on July 4, 2010 the Company signed a new transmission contract for a six-month period for a total of US$ 155 million to cover the energy transmission required by the Argentinean government. Based on its estimates on the different business alternatives, CIEN’s management considers that it will not have any problems in recovering all its net assets. It is expected that CIEN’s new business model will start operating during the next year. Note 16. Investment Property The detail of the composition of, and changes in, investment property during 2010 and 2009 is as follows: Investment Properties Opening Balance at January 1, 2009 Additions Disposals Depreciation Expense Impairment Losses Reversed Recognized in Consolidated Statement of Comprehensive Income(*) Balance at December 31, 2009 Additions Disposals Depreciation Expense Impairment Losses Reversed Recognized in Consolidated Statement of Comprehensive Income(*) Closing Balance Investment Property at December 31, 2010 ThCh$ 26,368,681 5,063,418 (2,985,275) (24,029) 2,809,044 31,231,839 1,303,676 (2,732,209) (24,029) 3,239,877 33,019,154 (*) Impairment losses reversed are presented in line item Reversal of impairment loss (impairment loss) recognized in profit or loss in the consolidated statements of comprehensive income, see Note 28. The fair value of the Group’s investment properties as of December 31, 2010 and 2009 determined on the basis of valuations carried out internally was ThCh$ 34,099,993 and ThCh$ 34,921,883, respectively. The selling price of investment properties disposed of in 2010 and 2009 was ThCh$ 8,015,891 and ThCh$ 7,369,162, respectively. The amounts recognized in profit or loss during 2010, 2009, and 2008 as direct operating expenses arising from investment properties were not significant.

The unrecognized tax losses can be carried forward indefinitely. The Group has not recognized deferred tax liabilities for taxable temporary differences associated with investment in subsidiaries, associates, and jointly controlled entities, as it is able to control the timing of the reversal of the temporary differences and considers that it is probable that such temporary differences will not reverse in the foreseeable future. The aggregate amount of taxable temporary differences associated with investments in subsidiaries, associates, and jointly controlled entities, for which deferred tax liabilities have not been recognized totaled ThCh$ 1,995,679,814 as of December 31, 2010 (Ch$ 931,081,512 as of December 31, 2009).

Such tax audits can be performed until the applicable statute of limitation expire. Tax audits by their nature are often complex and could require several years to complete. The following table sets forth a summary of tax years, potentially subject to examination, in the significant tax jurisdictions in which the Group operates: Country Chile Argentina Brazil Colombia Peru Period 2007-2010 2006-2010 2006-2010 2008-2010 2007-2010 Given the range of possible interpretations of tax standards, the results of any future inspections carried out by tax authorities for the years subject to audit can give rise to tax liabilities that cannot currently be quantified. Nevertheless, Enersis’s Management estimates that the liabilities, if any, that may arise from such audits, would not significantly impact the companies’ future results. The deferred tax effects of the components of other comprehensive income for the years 2010 and 2009 are as follows: Deferred tax effects of components of other comprehensive Income Available-for-Sale Financial Assets Balance at 12-31-2010 Balance at 12-31-2009 Balance at 12-31-2008 Income Tax Expense (Benefit) ThCh$ 31 Amount Before Tax ThCh$ (179) Amount Amount After Tax Before Tax ThCh$ (148) ThCh$ 61,031 Income Tax Expense (Benefit) ThCh$ (10,528) Amount Amount After Tax Before Tax ThCh$ 50,503 ThCh$ 436 Income Tax Expense (Benefit) ThCh$ (3) Amount After Tax ThCh$ 433 Cash Flow Hedge 30,911,303 (5,301,050) 25,610,253 192,801,668 (33,917,966) 158,883,702 (301,007,749) 46,849,978 (254,157,771) Foreign currency translation (138,554,045) — (138,554,045) (246,854,956 — (246,854,956 191,370,521 — 191,370,521 Actuarial income on defined benefit pension plans (48,495,375) 16,515,279 (31,980,096) (15,599,453) 1,369,374 (14,230,079) (34,060,925) 11,439,369 (22,621,556) Total (156,138,296) 11,214,260 (144,924,036) (69,591,710) (32,559,120) (102,150,830) (143,697,717) 58,289,344 (85,408,373) Note 18.

Hedged debt Of Enersis’s US dollar denominated debt, as of December 31, 2010, ThCh$ 679,999,810 is related to future cash flow hedges for the Group’s US dollar linked operating income (see Note 3.m.). As of December 31, 2009, this amount totals ThCh$ 964,291,218. The following table details movements in “Reserve of cash flow hedges” during 2010, 2009 and 2008 due to exchange differences of this debt: Balance in hedging at the beginning of year 60,346,205 (61,905,837) 128,332,092 Foreign currency differences exchange recorded in net equity 15,654,909 126,579,938 (179,193,798) Recognition of foreign currency exchange differences in profit or loss (8,252,587) (4,327,896) (11,044,131) Balance in hedging 67,748,527 60,346,205 (61,905,837) 12-31-2010 12-31-2009 12-31-2008 ThCh$ ThCh$ ThCh$ 18.5 Other information As of December 31, 2010 and 2009, the Enersis Group has long term lines of credit available for use amounting to ThCh$ 242,750,000 and ThCh$ 253,550,000, respectively. Various credit facilities of the Company and various of its subsidiaries contain certain financial covenant ratios, customary on these types of arrangements. Those credit facilities also include affirmative and negative covenants that require ongoing monitoring. Additionally, there are certain restriction in the events of default sections that also require compliance. Some of Enersis’s and Endesa Chile’s credit facilities include cross default provisions. Regarding the provision affecting Enersis, the loan subscribed on December 2009 under the New York jurisdiction that matures December 2012, points out that a cross default arises when Enersis, Chilectra or Endesa Chile become due with any one of its debt repayments. A similar provision applies to Endesa Chile with its loan syndicated under the State of New York law that matures in July 2011. According to that loan’s stipulations, a cross default can arise due to lack of payment of either interest or principal by Endesa Chile or its “Relevant Subsidiaries” as defined in the credit facility. Note that there have been no disbursements under either of these credit facilities as of December 2010. As for Endesa Chile’s loan that is syndicated the State of New York law, subscribed in 2008 and expiring in 2014, and which contains a disbursed balance of US$ 200 million as of December 31, 2010, the loan does not make reference to Endesa Chile’s subsidiaries, as a result, a cross default can only originate if Endesa Chile defaults on other of its own debt. For debt repayments to become accelerated due to cross default, the amount in default must exceed US$ 50 million, or its equivalent in other currencies. Additionally, other conditions must be met before debt repayments can be accelerated, including expiration of the grace period (if any) and a formal notice documenting intention to accelerate debt repayment from the lenders that represent more than 50% of the balance owed under the credit facility. Additionally, in December 2009, both Enersis and Endesa Chile subsribed loans under Chilean law that stipulate that a cross default will arise only by the debtor’s default. In these loans, the amount in default must also exceed the US$ 50 million threshold aforementioned or its equivalent in foreign currency. Note that since their subscription, these credit facilities have not been disbursed.

The acceleration of the debt repayment caused by the cross default provision does not happen automatically, instead, bondholders of at least 25% of a certain series of the Yankee Bonds must demand this. Additionally, the bankruptcy or insolvency of a foreign subsidiary does not have a contractual impact on Enersis’s and Endesa Chile’s Yankee Bonds. Enersis’s and Endesa Chile’s Chilean bonds stipulate that a cross default can only arise if the “Issuer” of the debt instrument (as defined in the debt agreement) is in default. Furthermore, the acceleration of the debt repayment must be requested by at least 50% of the bondholders of a particular series As of December 31, 2010 and 2009, Enersis S.A, Endesa Chile, and their respective subsidiaries were in full compliance with all above described financial and other covenants and restrictions. Note 19. Risk Management Policy The Group’s companies are exposed to certain risks that are managed by systems that identify, measure, limit concentration and supervise. Among the main basic principles defined by the Group are: Compliance with corporate governance standards. • Strict compliance with all of the Group’s internal policies. • Each business and corporate area defines: • I. Markets and products to operate based on its knowledge and ability to ensure an effective risk management. II. Criteria regarding counterparts. III. Authorized operators. • • • Business and corporate areas establish their risk tolerance in a manner consistent with the defined strategy for each market in which they operate. All of the operations of the businesses and corporate areas are performed within limits approved by the corresponding internal authorities. Businesses, corporate areas, lines of business and companies design risk management controls that are necessary to ensure that transactions in the markets are conducted in accordance with Enersis’ policies, standards and procedures. 19.1 Interest rate risk Changes in interest rates affect the fair value of assets and liabilities bearing fixed interest rates, as well as, the expected future cash flows of assets and liabilities subject to floating interest rates. The objective of managing interest rate risk exposure is to achieve a balance in the debt structure to minimize the cost of debt with reduced volatility in profit or loss. In compliance with the current interest rate hedging policy, the proportion of fixed debt and/or hedged debt over the net total debt was 51% as of December 31, 2010. Depending on the Group’s estimates and on the objectives of the debt structure, hedging transactions are performed by entering into derivatives contracts to mitigate interest rate risk. Derivative instruments currently used to comply with the risk Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 251 Financial Statements Consolidated management policy are interest rate swaps to set floating rate to fixed rate. The financial debt structure of the Group detailed by fixed, hedged and floating rate debt net of hedging derivatives instruments is as follows: Net position: Fixed Interest Rate Hedged Interest Rate Floating Interest Rate Total 12-31-2010 12-31-2009 % 51% 0% 49% 100% % 35% 1% 64% 100% 19.2 Exchange rate risk Exchange rate risks involve basically the following transactions: • • • • Debt contracted by the Group’s companies that is denominated in a foreign currency, when the Company’s contribution margin is not highly indexed to such foreign currency. Payments to be made in international markets for the acquisition of project related materials. Group company income directly linked to dollar changes. Cash flows from foreign subsidiaries to the Chilean parent company, exposed to exchange rate fluctuations. In order to mitigate the foreign currency risk, the Group’s foreign currency risk management policy is based on cash flows and considers maintaining a balance between U.S. dollar flows and the levels of assets and liabilities denominated in such currency. The objective is to minimize the exposure to variability in cash flows that are attributable to foreign exchange risk. The hedging instruments currently being used to comply with the policy are currency swaps and forward exchange contracts. In addition, the policy seeks to refinance the debt in the functional currency of each of the companies of the Group. 19.3 Commodities risk The Group has a risk exposure to price changes in certain commodities, basically due to: • • Purchases of fuel used to generate electricity. Energy purchase/sale transactions performed in local markets. The company has not entered into commodity derivative instruments to manage fluctuations in fuel prices; however, it is permanently analyzing and verifying the appropriateness of using this type of instruments, as such has not discarded its use in the future. In order to reduce the risk in situations of extreme drought, the company has designed a commercial policy by defining the levels of sales commitments in line with the capacity of its generating power plants in a dry year and including risk mitigation terms in certain contracts with unregulated customers.

The projected needs above include maturities of financial debt, net of financial derivatives. For further details regarding the features and conditions of financial obligations and financial derivatives, see Notes 18, 20 and Appendix No. 4 As of December 31, 2010, the Group has cash and cash equivalent totaling ThCh$ 961,355,037 and unconditional available lines of credits totaling ThCh$ 242,750,000. As of December 31, 2009, the Group had ThCh$ 1,134,900,821 in cash and cash equivalents and ThCh$ 253,550,000 in unconditional available lines of credit. 19.5 Credit risk Given the current economic situation, the Group has been conducting detailed monitoring of its credit risk. Trade receivables: The credit risk for receivables from the Group’s commercial activity has historically been very low, due to the short term period of collections from customers, resulting in non significant cumulative amounts of receivables. The above trend applies to our electricity generating and distribution lines of business. In our electricity generating line of business, the regulations in certain countries, allow the suspension of the energy service to customers with outstanding payments, and most of the contracts have termination clauses for payment default. The Company monitors on an ongoing basis its credit risk and measures quantitatively its maximum exposure to the payment default risk, which as stated above, is very low. In our electricity distribution line of business, the suspension of the energy service for payment default of our customers is permitted in all cases, in accordance with current regulations in each country, which facilitates our credit risk management, which is also very low. Financial assets: Cash surpluses are invested in highest rated local and foreign financial entities (with risk rating equivalent to investment grade) with established thresholds for each entity. In order to select the banks where to invest, those banks with at least two investment grade ratings received from the three major international rating agencies (Moody’s, S&P y Fitch), are selected to make the investments. Investments are supported with treasury bonds from the countries where the company operates and/or with commercial paper issued by highest rated banks, where depending on the circumstances and market conditions treasury bonds are preferred. Derivative instruments are entered into with entities with solid creditworthiness, where approximately 90% of the derivative transactions performed are with A or higher rated entities.

The portfolio of positions included in order to calculate the current Value at Risk consists of the following: Debt Financial derivatives • • The VaR determined represents the potential loss in value of the portfolio of positions described above in one-day with a 95% confidence level. To determine the VaR, we take into account the volatility of the risk variables affecting the value of the portfolio of positions including: • • U.S. dollar Libor interest rate. The customary local indices used in the banking industry for the debt, considering the various currencies in which our companies operate • The exchange rates of the various currencies included in the calculation. The calculation of VaR is based on generating possible future scenarios (at one day) of market values (both spot and term) for the risk variables, using Monte Carlo simulations. The number of scenarios generated ensures compliance with the simulation convergence criteria. The table of volatilities and correlations between the various risk variables calculated based on the historical values of the logarithmic price return has been applied to simulate the future price scenario. Once the price scenarios have been obtained, the fair value of the portfolio is calculated using such scenarios, thereby obtaining a distribution of possible values at one day.

Law 25,561, known as Public Emergency and Reformation of Exchange Regime, enacted on January 6, 2002 by the Argentine authorities, rendered ineffective certain terms and conditions of the concession contract entered into by the subsidiary Edesur. In addition, this Law provided that concession contracts involving public services would have to be renegotiated over a reasonable term in order to adapt them to the new circumstances. However, the fact that the concession contract entered into by Edesur was not renegotiated prompted Enersis S.A., Chilectra S.A., Endesa Chile and Elesur S.A. (currently, Chilectra S.A.) to submit in 2003 a petition for arbitration in accordance with the Chilean-Argentine Treaty for Promotion and Protection of Investments, with the International Center for Resolution of Disputes involving Investments (known as CIADI). The filing put forward as main petition that the involved investments would be declared expropriated, with ensuing payment of damages totaling US$1,306,875,960. In the alternative, a payment of damages was requested, totaling US$318,780,600, based on the negative effects on claimants’ investments caused by a lack of fair and equal treatment; in both cases, subject to a compounded interest of 6.9% a year. In addition, the petition sought payment of the damages generated Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 261 Financial Statements Consolidated starting on July 1, 2004. Finally, it requested payment of US$102,164,683 to Elesur S.A. (currently, Chilectra S.A) for the loss it suffered in the sale of its shares. On June 15, 2005, the Argentine authorities and Edesur signed the documentation underlying a so-called “Acta de Acuerdo” (Written Agreement), which was not rejected by the Argentine parliament, and which was later ratified by the Executive branch of the Republic of Argentina. The Written Agreement sets forth terms and conditions that modify and supplement the concession contract, and establish changes in rates, first during a transitory period and then through a thorough rate review process aimed at laying down the conditions for rates for a 5-year period. Arbitration was suspended in March of 2006 in compliance with the Written Agreement. When suspended, arbitration had reached a stage at which the arbitral tribunal was required to notify the parties of its ruling on the matter of jurisdiction raised by the Republic of Argentina. The current suspension is the result of several extensions requested by the plaintiffs. Regarding the most recent extension, dated August 6, 2009, the arbitral tribunal had requested the parties to report on the status of the negotiation process envisaged in the Written Agreement. On August 12, 2009, the claimants answered this request and filed a petition seeking to extend the suspension of the arbitration process for an additional 12 months, beginning on the date of that filing. The Argentine Republic indicated that it did not oppose the extension of the suspension period requested by the claimants. On August 25, 2009, the Company received a communication from the arbitral tribunal, which agreed to maintain the suspension of the arbitration proceeding until August 12, 2010 at which time, the arbitral tribunal indicated it will request the parties to report on the status of the negotiation process in conformity with the Written Agreement. In a communication dated September 30, 2010, the arbitral tribunal requested a status report, which the claimants responded to by requesting a new 12 month extension on the suspension period. On October 13, 2010, the arbitral tribunal communicated its approval of the suspension of the proceeding until October 6, 2011. At the end of this period, the arbitral tribunal will request the parties involved to inform it regarding the status of negotiations in accordance with the Written Agreement. On October 15, 2010, Robert Volterra, one of the arbitrators, submitted his resignation, which was accepted by the other two arbitrators. According to applicable law, plaintiffs must now assign a replacement for Mr. Volterra within a 45 day period starting with the date when the resignation was communicated. Nevertheless, on November 10, 2010, the plaintiffs requested the suspension of the proceeding with regard to the designation of the substitute for Robert Volterra, with which request the Argentine Republic agreed. 2. Meridional Servicios, Emprendimientos y Participaciones (hereinafter, “Meridional”) is a company whose only assets are the rights derived from litigation that it acquired from the construction companies Mistral and CIVEL, which had entered into a contract with Centrais Elétricas Fluminense S.A. (“CELF”) for the construction of civil works. This contract was cancelled by CELF prior to the privatization that gave rise to the Brazilian distribution subsidiary called Ampla. Since CELF’s assets were transferred to Ampla in the privatization process, in 1998 Meridional sued Ampla, alleging that such assets were transferred in violation of Meridional’s rights. It should be pointed out that Ampla only acquired assets from CELF, but is not CELF’s legal successor, because CELF, a State-run company, continues to exist as a separate legal entity.

The plaintiff is seeking payment in an amount estimated at US$430.31 million. The lower court ruling was in favor of Ampla and appealed by the plaintiff, which was granted. Ampla filed a new petition (“embargos de declaración”) with the objective of negating the previous decision and obtaining a new trial. On June 2, 2009, the courts ruled in favor of Ampla and annulled the resolutions issued in past proceedings dating back to April 4, 2009. According to the resolutions dated December 1, 2009 and December 15, 2009, the ruling that granted the relief sought by Meridional was amended and reformulated thereby maintaining the first ruling in favor of Ampla and the State of Rio de Janeiro. Against that decision, Meridional appealed again (via a embargo de declaracíon), which was ruled inadmissible on February 23, 2010. In May 2010, Meridional presented a new petition (embargo de declaracíon), against the aforementioned agreement, which was also declared inadmissible and Meridional was issued a warning that it would be penalized if it filed any future frivolous appeals. On May 28, 2010, Meridional presented a new petition (grievance procedure), which was unanimously rejected on June 8, 2010 and Meridional was assessed a fine equal to 1% of the value of the claim, since the petition was deemed groundless and delayed the trial. In July 2010, Meridional presented a new petition (embargo de declaracíon), which was not recognized. Against such decision, Meridional filed a new petition (regimental tort). On August 30, 2010, the Rapporteur decided to not admit the petition and determined that the petition be removed from the process. Moreover, the Rapporteur asked the tribunal secretary to discourage the admission of new petitions from Meridional as well as to issue a certificate called “transito em julgado” (res judicata) indicating that the matter has already been settled in court. Based on this decision, on September 13, 2010, Meridional filed a new petition (mandado de segurança (injunction). 3. During 2002 the Brazilian distribution subsidiary Ampla signed with Enertrade Comercializadora de Energía S.A. (“Enertrade”) a contract for the purchase of electricity lasting 20 years effective December 31, 2002. This contract was sent for evaluation and approval to Agencia Nacional de Energía Eléctrica (“ANEEL”), and ANEEL indicated that the price for energy would have to be lower. Based on that decision, Ampla paid for the contract the price authorized by ANEEL. However, in December 2005 Enertrade initiated an arbitration proceeding against Ampla with Cámara de Conciliación y Arbitraje de la Fundación Getúlio Vargas/RJ. On March 19, 2009 the arbitral tribunal issued a ruling that ordered Ampla: i) to pay the difference between the price set forth in the contract and the amount actually paid in the period from January 1, 2004 to August 28, 2006, adjusted and with interest; ii) to pay for October to December 2003 an updated price plus interest and a 2% penalty. In addition, the arbitral tribunal ruled that the contract had ended on August 28, 2006 and that Ampla owes nothing to Enertrade after that date. Ampla filed a petition seeking the annulment of the arbitration ruling, including a petition (“anticipación de tutela”) asking that execution of the arbitration ruling be suspended until a final ruling be passed in a pending trial of Enertrade vs. ANEEL (“mandato de seguridad”), where administrative approval of the same energy purchase contract taken to arbitration is being discussed. The amount involved is estimated at US$41.3 million. On May 22, 2009 the “anticipación de tutela” was granted, which suspended the effects of the arbitration ruling. On June 30, 2009 an Enertrade petition was rejected and the suspension was upheld. On July 9, 2009 an Enertrade petition (agravo de instrumento) against the ruling was rejected. On July 20, 2009 Enertrade filed another petition (agravo regimental) against the resolution that rejected the Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 263 Financial Statements Consolidated previous petition. On August 25, 2009 the petition (agravo regimental) filed by Enertrade was rejected. Ampla filed a response that included the lower court ruling passed in the trial (“mandado de seguranca”) of Enertrade vs. ANEEL (on July 7, 2009 a lower court ruling rejected Enertrade’s allegations). On September 2, 2009 a court order was sent to the CCEE (Cámara de Comercialización de Energía Eléctrica) informing it of the “anticipación de tutela” so that the CCEE would suspend the execution of the arbitration ruling until a final decision is passed on the annulment petition. On September 28, 2009 the ruling passed in the trial between Enertrade vs. ANEEL became final —a ruling that indicated that the parties were obligated to add to the contract the conditions imposed by ANEEL (the price reduction). On November 11, 2009 both parties filed a joint petition requesting suspension of proceedings for 30 days and in December they requested the continuation of that suspension. On March 17, 2010, the parties requested the termination of the suspension period as the parties could not reach an agreement. On June 2, 2010, the courts ruled favorably towards Ampla on the petition filed by Enertrade (“Agravo de Instrumento”) (instrumental grievance). As a result of the arbitration, ANEEL approved the agreement (“Termo Aditivo”) between Ampla and Enertrade that adjusts the power purchase agreement. The lower court judge convened a conciliation hearing on September 13, 2010. On August 2, 2010, Enertrade filed a new petition (embargo de declaración) with the Court of Justice seeking reversal of the lower court ruling. On August 26, 2010, the Court of Justice confirmed the lower court ruling in favor of Ampla. However, Enertrade can present an appeal to the Superior Courts of Brasilia. On September 10, 2010, Ampla and Enertrade requested a new suspension of the process for 90 days to resume negotiations and implement the agreement. The Court adjourned, without setting a date, the conciliation hearing previously set for September 13, 2010. 4. Companhia Brasileira de Antibióticos (“CIBRAN”) sued the Brazilian distribution subsidiary Ampla seeking payment of damages for loss of products and raw materials and break-down of machinery, among other things, which allegedly was caused by Ampla’s poor service between 1987 and May 1994. CIBRAN is also seeking payment of punitive damages. The amount involved is estimated at approximately US$45.7 million. The lawsuit was added to six other proceedings whose foundation is disruption of energy. On June 21, 2010, the judge required the parties and their technical advisors to comment on the expert’s report and granted a 30 (thirty) day period for this event. The expert’s report was unfavorable towards Ampla. Consequently, on August 27, 2010, Ampla challenged the report pointing out contradictions in the report and requesting the annulment of the expert’s report or questioning of the expert by the Company’s technical advisors. 5. On October 26, 2009 Tractebel Energía S.A. sued CIEN for alleged failure to perform the agreement called “Purchase and Sale of 300 MW of firm capacity with associated energy from Argentina” (Contrato de Compra y Venta de 300 MW de Potencia firme con energia asociada proveniente de Argentina) entered into in 1999 by and between CIEN and Centrais Geradoras do Sul do Brazil S.A (Gerasul — currently, Tractebel Energia S.A.). Tractebel Energia S.A. is asking the court to order CIEN to pay a penalty of R$ 117,666,976.00 (US$ 70,880,000) plus other fines, for non-availability of “firm capacity and associated energy”, and it asks the court to determine those other fines in the ruling. Non-performance by CIEN was alleged to occur because of the failure of CIEN to guarantee to Tractebel the availability of the firm energy power capacity that was contractually guaranteed to Tractebel, which would allegedly have occurred since March of 2005. On November 27, 2009 CIEN Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 264 Enersis 2010 Annual Report 6. 7. answered the lawsuit, arguing that the non-availability of energy was caused by the “Argentine crisis”, since Argentina is the country from which CIEN imports all the energy that it delivers, when needed, to Tractebel Energia S.A. The defendant also alleges that the “Argentine crisis” was an unexpected event, for which CIEN has no responsibility, and that this situation was even acknowledged by the Brazilian authorities of that period. On April 9, 2010, CIEN presented to the court a written statement regarding the reply submitted by Tractebel. The lawsuit is currently in the lower court and at an initial stage. On September 1, 2010, the lawsuit was sent to the judge for him to decide whether to grant a motion (despacho saneador) to conclude the parties’ pleadings and initiate the investigation/production of evidence. Lawsuit filed by Fumas Centrais Eletricas S.A. (“Fumas”) and notified on June 15, 2010 based on alleged breach of CIEN’s power purchase Agreement N° 12,399 for the purchase of 700MW of capacity with energy originating from Argentina. Under the agreement, which was signed on May 5, 1998, CIEN commits itself to purchase energy from the Argentina’s electricity wholesale market (Mercado Eléctrico Mayorista de la República Argentina hereinafter “MEM”) and transport it from the Argentine electric system (Sistema Eléctrico Argentino) to the Brazilian transmission interconnection system (Sistema de Transmissao de Interligacao) at the Itá substation. The contract has a 20 year term effective June 21, 2000. On April 11, 2005, CIEN informed Fumas that it will not be able to fulfill the agreement due to events beyond its control, regarded as force majeure. On April 14, 2005, Fumas notified CIEN that it would reject CIEN’s force majeure claim. Fumas is requesting the courts order CIEN to pay a R$520,280,659 (US$313.42 million) fine contemplated in the contract in case of rescission, as adjusted plus interest from the date of filing of the claim until actual payment, as well as other penalties based on the lack of availability of the contracted capacity, and other charges to be determined upon the issuance of the final verdict. CIEN replied on July 28, 2010. Fumas answered on August 26, 2010. On October 4, 2010, the judge ruled that the trial is at a stage when the parties need to present their evidence. On October 25, 2010, CIEN proposed the courts the production of additional documentary proof without any need at this time to specify what documents would be presented, which will occur during a future phase. In December, 2001 the article of the Federal Constitution, on which our Brazilian distribution subsidiary, Ampla, relied to argue it was not required to pay certain taxes (COFINS, Contribuição para o Financiamento da Seguridade Social) and pursuant to which Ampla did not pay tax, was amended. There is an article of the Constitution stating that legislative changes come into force 90 days after their publication. Based on that, Ampla began to pay the COFINS only as of April, 2002. However, the Brazilian Tax Authorities argue that this article of the Constitution only applies to changes in laws, but not to the Constitution itself, whose changes come into force immediately. Furthermore, the Tax Authorities argue that, by reason of the change in Ampla’s tax status (from earned to accrued) the taxable amount of the COFINS increased during the first semester of 2002. Notice was given of the proceedings in July 2003. The first appealable decision was decided against Ampla, and it filed an appeal in October, 2003. In November 2007, the appeal was ruled on by the court of appeals and the decision was partly favorable to the Treasury in terms of the period in which a change in the Constitution comes into force and partly favorable to Ampla in terms of the change in the tax status from earned to accrued. In April, 2008, the Ministry of the Treasury filed an appeal against this decision in the Higher Court of Appeals. In October, 2008, Ampla filed its answer to the appeal and also filed an appeal Contents Cover Resume Chairman’s Letter to Shareholders 2010 Highlight Main financial and operational indicators Identification of the Company Ownership and control Administration Human resources Stock Exchange Transactions Dividends Investment and financing policy 2010 The company´s businesses Investments and financial activities Risk factors Regulatory framework of the electricity industry Description of the business by Country Other businesses Sustainability Diagram of shareholdings Consolidated relevant facts Identification of subsidiaries and related companies Declaration of responsibility Consolidated Financial Statements Summarized Financial Information for Subsidiaries 1 2 4 10 16 20 24 28 38 44 50 56 60 66 78 84 100 128 132 136 144 154 180 182 326 pages control previously next 265 Financial Statements Consolidated with the Higher Court to attempt to change that part of the decision that was not favorable to Ampla. In May, 2009, the Federal Treasury (Hacienda Pública Federal) applied interest to the fine imposed. This new interest arises from an internal administrative act (addressed to the tax authorities but for general application) of the tax authorities and has started to be applied uniformly by the Federal Treasury (SRF). The interest on the fine has been calculated by applying the Selic (Special System of Liquidation and Custody: an adjustment index set by the federal government based on the referential interest rate of the Brazilian Central Bank), as of the month after receiving the Record of Infringement. Consequently, since the Record was received in July, 2003, the Selic corresponds to the interest accumulated as of August 2003, which is 81.42%. In August, 2009, Ampla was notified that the Special Appeal filed by the company had not been admitted to be heard. Ampla filed another appeal against this resolution with the President of the Higher Court for hearing Tax Issues. The purpose of this appeal is for the Special Appeal to be received. The decision on the Special Appeal filed by the SRF is pending. The appeal filed by Ampla with the President of the Higher Court for Tax Issues is also pending resolution. The amount involved is US$95.63 million. In 1998, our Brazilian distribution subsidiary Ampla issued FRNs (bonds) for US$350 million maturing in 2008 in order to finance its investment in Coelce. Such bonds were purchased by Cerj Overseas (a foreign subsidiary of Ampla). The bonds had a special tax treatment according to which no withholding tax (15% or 25%) would be applied to payments of interest abroad, provided that, among other requirements, there was no advanced amortization before the average 96 month amortization deadline. Cerj Overseas obtained financing through a 6-month loan outside Brazil to acquire the bonds. At the end of that period (October 1998), due to problems in obtaining other sources of financing, Cerj Overseas had to obtain re-financing from Ampla, which provided Cerj Overseas with loans in reales. The Brazilian tax authorities argue that the special tax treatment was lost in 1998 because the loans in reales made by Ampla to Cerj Overseas were the equivalent of an advanced amortization of the debt before the 96 month amortization deadline. A Record of Infringement was notified in July 2005. In August, 2005, Ampla filed an appeal with the lower administrative court of appeal and such appeal was rejected. In April 2006, an appeal was filed with the Council of Taxpayers, the intermediate administrative court (Consejo de Contribuyentes). In December, 2007, the Council of Taxpayers ruled completely in favor of Ampla. In January of 2010, Ampla was notified of this favorable decision by the Council of Taxpayers as well as the appeal filed by Hacienda Pública. In February 2010, Ampla presented its arguments against the appeal filed by the tax authorities. The amount of this lawsuit is US$430.35 million. In 2002, the State of Rio de Janeiro (“RJ”) issued a decree stipulating that the ICMS (Imposto sobre operações relativas à circulação de mercadorias e sobre prestações de serviços de transporte interestadual, intermunicipal e de comunicação) should be calculated and paid on the 10th, 20th, and 30th days of the same month of the accrual. Due to cash problems, our Brazilian distribution subsidiary Ampla continued to pay the ICMS in accordance with the previous system (payment on the 5th of the month following its accrual). In October 2004, and notwithstanding the existence of an informal agreement with RJ and two separate amnesty laws, RJ notified Ampla of a resolution to collect a fine on late payments. Such resolution was appealed by Ampla in that same year. In February 2007, Ampla was notified of the administrative decision that ratified the fine imposed by RJ. In March 2007, Ampla filed an appeal with the Council of Taxpayers, the intermediate 8. 9.

Ampla obtained a temporary ruling (liminar) in its favor, allowing it to file the appeal without the need to make a deposit or post a bond to guarantee 30% of the adjusted amount of the fine. On August 26, 2010, Ampla received notification that the Council of Taxpayers decided against it. Afterwards, on September 1, 2010, Ampla presented a new appeal to the Full Council (Consejo Pleno, special body of the Council of Taxpayers) to reverse the decision of the Council of Taxpayers. Ampla is currently awaiting the decision from the Full Council. The amount of the lawsuit is US$ 97.67 million. 10. Towards the end of 2002, our Brazilian generating subsidiary CGTF filed a petition against the Federal Union seeking to classify the goods imported for the turbo-generator units as corresponding to the item “Other Generating Sets”, in order to be able to avail itself of the 0% rate for Import Tax (II) and for the Tax on Industrialized Products (IPI). The Federal Union argues that the imported goods do not correspond to “Other Generating Sets”. CGTF obtained an incidental resolution in its favor allowing it to clear the goods through customs with a 0% rate, subject to a prior legal deposit of R$56 million (US$35.72 million, updated at July 2009). Also, to avoid expiration of the taxes, the Brazilian federal tax authorities issued a record of tax enforcement that was suspended until the pending lawsuit against the Federal Union is resolved. In September of 2008, the lower court issued a ruling favorable to CGTF. The ruling recognized the classification of the turbo-generator units in accordance with CGTF’s original classification and determined that the judicial deposit should remain as a guarantee until a final decision is reached. In February 2009, the Brazilian federal tax authorities filed an appeal with the Regional Federal Court (Tribunal Regional Federal or “TRF”). In May of 2010, the TRF also ruled in favor of CGTF thereby confirming the decision of the lower court in favor of CGTF and rejecting the appeal filed by the Brazilian tax authorities. This decision became final as the Brazilian tax authorities did not file any appeal with the superior courts. In September 2009, the temporary resolution that allowed CGTF to clear the goods through customs with a 0% tax rate subject to a legal deposit was confirmed. In October 2009, the decision which confirmed the first ruling in favor of CGTF was published. In November 2009, the Brazilian tax authorities presented a special petition (embargos de declaracion) against such resolution which was resolved in favor of CGTF. In March 2010, the Brazilian tax authorities filed a special petition against such decision in the Supreme Court of Justice in Brazilia. In administrative proceedings regarding the tax enforcement issued by the Brazilian tax authorities to avoid expiration of the taxes, the lower administrative court ruled in favor of CGTF because the record of enforcement (Acta) was declared null and void. The decision is based on the fact that the record of enforcement was issued without taking into consideration the proper legal requirements and formalities. As this resolution was based on formalities (rather than on substantive matters), there is the theoretical possibility for the Brazilian tax authorities to issue another record that meets the formal requirements, for which there is no specific deadline. In October 2008, the Council of Taxpayers, the intermediate court of administrative appeal, completely ratified the decision by the lower court confirming that the record of enforcement issued by the Brazilian federal tax authorities was null and void due to formal flaws. In April 2009, such decision became final and therefore the record is now extinct. The lawsuit is currently pending resolution of a petition submitted by the Brazilian tax authorities to the Supreme Court of Justice in Brasilia. The amount involved is US$43.92 million.

In 2005, three lawsuits were filed against Endesa Chile, the Treasury (Fisco) and the General Water Board (Direccion General de Aguas or DGA), which are currently being treated as a single proceeding. The lawsuits request the annulment of DGA Resolution 134 that gave Endesa the right to non- consumptive use of water for the Neltume Hydroelectric Power Plant project. The lawsuits also request compensation for damages. Alternatively, the lawsuit requests compensation for damages allegedly caused to the plaintiffs by the loss of quality of their properties on the shores of Lake Pirehueico and by the loss in value of their properties. The defendants, including Endesa Chile, have rejected these allegations on the grounds that, among other arguments, the DGA Resolution 134 meets all legal requirements and the exercise by Endesa Chile of this right does not cause any damages to the plaintiffs. At this date, the proceeding is at the stage of receiving evidence by the parties. The amount related to these lawsuits is undetermined. 12. There were five proceedings initiated between 2008 and 2009 against Pangue S.A., a subsidiary of Endesa Chile, where the plaintiffs seek compensation for losses incurred by flooding that, according to the plaintiffs, was caused by the operation of the Pangue S.A. hydroelectric power plant during July 2006. Pangue S.A. responded to such lawsuits arguing that it was in compliance with existing regulations in the operation of the power plant and that it acted with due diligence and care. Consequently, Pangue S.A. claims that there is no causal relationship between the flooding and the operation of the power plant during the relevant period. These proceedings were filed in various courts and currently one of them is close to being resolved and two of them are at the discovery stage. In one of the two remaining proceedings, the courts ruled in favor of Pangue S.A., and currently there are pending appeals filed with the court of appeals by the plaintiffs. The remaining proceeding is no longer in effect due to inactivity by the plaintiffs. The amount claimed in the four proceedings that are still in effect is equal to ThCh$ 17,718,704 (US$ 37.86 million) in the aggregate. As for the proceeding that was closed, it entailed ThCh$ 1,916,466 (US$ 4 million) and is not covered in terms of equity risk by an insurance company. The potential damages arising from the four proceedings that are in effect are covered by insurance. 13. During 2010, several plaintiffs initiated four judicial proceedings against Endesa Chile seeking compensation for flooding of the Bio Bio river in the VIII Region. In these proceedings, the plaintiffs blame the company for losses attributed to the poor operation of the Ralco hydroelectric power plant during the flooding. In one of the proceedings, the lawsuit also includes the Public Works Ministry (“MOP”). In November 2010, the plaintiff withdrew the claim against Endesa but decided to continue it against MOP. The remaining lawsuits are currently in evidentiary hearing. The plaintiff has the burden to prove causation between the operation of the Ralco hydroelectric plant and the flooding during the period in question (i.e., that the flooding was caused by poor operation of the plant). The amount of the three proceedings that are currently in effect against Endesa Chile equals ThCh $ 14,610,043 (US$ 31.21 million). The proceeding against Endesa Chile that was dismissed by the plaintiff amounted to ThCh$33,751,490 (US$72.11 million). All of the risks arising from these proceedings are covered by an insurance policy. In July and September of 2010, Ingeniería y Construcción Madrid S.A. and Transportes Silva y Silva Limitada, filed separate lawsuits against Endesa Chile and the Dirección General de Aguas (“DGA”), to nullify and void the administrative resolution that granted to Endesa Chile use of the water rights for the Neltume hydroelectric plant, and the administrative resolution that authorized the transfer of the collection point of such rights. The goal of the 14.

Endesa Chile has rejected the claims, arguing that the plaintiffs are attempting to unlawfully litigate to prevent the construction of the plant in order to obtain compensation. The discussion period in the proceeding initiated by Ingeniería y Construcción Madrid S.A has expired and Endesa Chile has responded to the lawsuit in the proceeding initiated by Transportes Silva y Silva Limitada. The amount involved in these proceedings are undetermined. In 2001, the inhabitants of Sibaté, Department of Cundinamarca filed a claim against the Colombian generating subsidiary Emgesa S.A. ESP., Empresa de Energía de Bogotá S.A. ESP. and the Corporación Autónoma Regional seeking joint and several damages caused by the pollution of the El Muña reservoir by pumping of polluted water from the Bogotá river by Emgesa S.A. ESP. Emgesa responded that it is not liable for these damages, arguing, among other things, that it receives already polluted water. The total amount of the lawsuit equals ThCPs 3,000,000,000 (US$1,547.72 million). Emgesa S.A. ESP. petitioned to have approximately 80 public and private entities that discharge into the Bogotá River and that have responsibility for the environmental management of this river basin to be brought into the lawsuit. Therefore, the case file (expediente) was sent to the State Council (Consejo de Estado) and the public and private entities have filed petitions in opposition. On June 29, 2010 the parties were notified of a motion filed by one of the plaintiffs that seeks to declare the Cundinamarca Administrative Court’s rulings for the period after August 1, 2006 null and void. This request is based on the argument that the court lacks jurisdiction over this proceeding since according to Law 472 of 1998, the Administrative Circuit Courts are the relevant courts to hear class actions. Emgesa rejected such annulment request. The proceedings will be reassigned to Magistrate Olga Valle de la Hoz who is among the new magistrates that are in compliance with Law 1285. In 2001, the tax authority in Peru, SUNAT, issued certain tax and penalty resolutions questioning the depreciation of Edegel’s revalued assets. In January of 2002, Edegel filed a petition (recurso de reclamacion) against these resolutions, which was declared without merit by the SUNAT. Edegel filed an appeal before the Tribunal Fiscal de la Nación (National Tax Tribunal), which ruled in favor of Edegel in 2004, confirming (i) Edegel’s right to depreciate the greater value of the asset based on the fact that Edegel had an agreement for legal stability (convenio de estabilidad jurídica), and (ii) the non-application of Rule VIII of the Internal Revenue Code as there was no fraud. The resolution provided that SUNAT must ensure that the revaluation of the assets was not done at an amount greater than market value. From that date, Edegel has received several notices from SUNAT for determination of the revaluation surplus and the tax amount owed. In January 2006, a complaint and appeal were filed against the resolution of SUNAT before the Tribunal Fiscal de la Nación, the ruling of which is pending. The amount of these claims equals approximately US$ 45.43 million. The Management of Enersis S.A. considers that the provisions recorded in the Consolidated Financial Statements adequately cover the risks of the litigation described in this note, so such litigation is not expected to give rise to any additional liabilities to those recorded. Given the characteristics of the risks covered by these provisions, a reasonable schedule of dates of payment, if any, cannot possibly be determined.

Subsequent regulations stated that electricity generating companies will receive for supplying energy to non-contracted distribution companies the node price effective at that time and that they would be credited or charged the positive or negative differences, respectively, arising in respect to the marginal cost. In addition, it was also stated that such differences may not be more than 20% of the node price, if so, the remaining balances will be incorporated in subsequents node prices’ calculations, until such differences be fully settled. The estimated recoverable balance of our subsidiary Endesa Chile totaled Ch$ 66,000 million as of December 31, 2010. Such remaining balance will be recovered by the distributions companies through increases in the tariff rate that will be applied and billed from future energy consumptions by the regulated customers in the Energy System.

The main purpose of this audit is to verify Edesur’s compliance with its obligations and acquired commitments. The comprehensive audit under consideration started on January 5, 2011. As of the issuance of the financial statements, E.N.R.E.’s comprehensive audit is ongoing in accordance with the terms and conditions defined by E.N.R.E.. Edesur continues with its activities in the ordinary course of business and continues providing electric distribution services to the public in a regular and continuous manner, thereby meeting its current legal obligations. Management estimates that the results of the audit will not have a significant impact in Enersis’s consolidated financial statements. No other significant events have occurred between December 31, 2010 and date of issuance of these financial statements that could materially affect the presentation of the financial statements.
