RE: Significant Event

To whom it may concern,

Pursuant to articles 9 and 10, paragraph 2 of the Securities Market Law (18,045), the provisions of General Norm 30 of the Superintendence, and in the exercise of the powers bestowed upon me, I hereby inform you as significant event that on December 20, was held the Extraordinary Shareholders´ Meeting (ESM) which resolved about the capital increase of Enersis S.A.. In the ESM , a very large majority, almost 86% of all shareholders present with voting rights, equivalent to 81.94% of the total shares with voting rights of the Company, approved the capital increase of the following characteristics:

2) Value of non in-kind contributions to be capitalized: The total issued capital of Cono Sur, Company that will concentrate the activities that are identified in the reports that have been made available to the shareholders and that would be contributed by Endesa to Enersis S.A., will amount to Ch$ 1,724,400,000,034 corresponding to 9,967,630,058 shares of Enersis S.A. at a price of Ch$ 173 per share. This is a reference value of US$ 3,634,754,015.5 at an observed exchange rate of Ch$ 474.42 per dollar of the United States of America as of December 20, 2012.

3) Placement share price: A fixed price of Ch$173 for every payment share to be issued as a result of the capital increase.
