MATERIAL INFORMATION

Dear Sir:

In accordance with clauses 9 and 10.2 of the Securities Market Law 18,045 and General Rules Nos. 30 and 210 of the Superintendency of Securities and Insurance, and in the use of the powers conferred upon me, I inform the following Material Information:

Today, in a stock-market transaction carried out on the Lima Stock Exchange, Peru, Enersis S.A. acquired 153,255,336 shares representing 24% of the share capital of its Peruvian subsidiary Empresa de Distribución Eléctrica de Lima Norte S.A.A. (“Edelnor”), at a cost of 2,72 soles per share, which results in a total acquisition cost of US$ 145,753,327. The seller of the stock package was Generalima, S.A., a Peruvian company fully owned by Endesa Latinoamérica, S.A., the parent company of Enersis S.A.. After this transaction, the direct and indirect ownership stake of Enersis S.A. in Edelnor increased from 33.53% up to 57.53%. It’s worth mentioning that previous to this operation, Edelnor was already a subsidiary and was controlled by Enersis S.A.

Finally, we informed that considering that Edelnor is already consolidated in the Financial Statements of Enersis S.A., this transaction will not imply important changes over assets, liabilities and results of the Company. Despite the above, a consequence of this operation will be an increase on Profit (Loss) of the Parent company and a decrease in Profit (Loss) of the Minorities Shareholders.

Sincerely,

Ignacio Antoñanzas Alvear
Chief Executive Officer
