Reg.: REPORTING AN ESSENTIAL EVENTS

Dear Sir:

Pursuant to the provisions set forth under Articles 9 and 10, paragraph 2 of Law 18,045, Rule No. 30 of the General Regulations of the Office of the Superintendent of Securities and Insurance, and Resolution No. 1228 dated 23 May 2007 of the Chilean Central Bank, and in keeping with the powers vested in me, I hereby inform you of the following, deemed an essential event:

1. The Council of the Chilean Central Bank adopted Agreement No. 1333-01-070510, by way of which it proceeded to construe the provisions contained in the now-abolished version of Chapter XXVI of the Chilean Central Bank’s Compendium of Rules on International Exchange (deleted in April 2001), with a view to expanding its application to include capital increases carried out subsequent to 18 April 2001 by companies holding American Depositary Receipts (ADRs). The latter is subject to compliance with certain requirements provided under Resolution No. 1228, dated 23 May 2007, of the Chilean Central Bank.

2. On September 24, 2008, Enersis S.A. entered into an agreement with the Chilean Central Bank and Citibank N.A., as the depositary bank (the “Agreement”). The Agreement grants the benefits of the aforementioned Chapter XXVI for a total of 24,360,146,365 subscribed and paid-up shares, resulting from the capital increase approved by the Special Shareholders’ Meeting of Enersis S.A., held on 31 March 2003.

3. The Agreement stipulates that the benefits included thereto regarding to March 2003’s capital increase (24,360,146,365 shares), shall be subject to a final condition consisting of the following: prior to any further capital increase by Enersis S.A., the Chilean Central Bank must be informed on the safeguards adopted in line with the requirements set forth under section III of the Resolution N° 1228 to properly identify which shares are included under the Agreement. Those safeguards shall provide that once shares are issued in conjunction with a future capital increase, two series of shares shall be created in order to differentiate between shares included under the abovementioned version of Chapter XXVI and those that do not qualify to receive those benefits.

Best regards,

Ignacio Antoñanzas A.
