MATERIAL INFORMATION

Dear Sir:

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

On December 4, 2009, the Ministry of Economy, Development and Reconstruction published on the official gazette Decree N° 197, which “ESTABLISHES PRICES OF SERVICES NON CONSISTENT WITH ENERGY SUPPLY, RELATED TO ELECTRICITY DISTRIBUTION”. This Decree rules since its publication date.

As a consequence of the application of the mentioned Decree, the negative effects over Enersis S.A.'s future results are estimated in 2,500 million Chilean pesos per annum before taxes and minorities, which corresponds to a decrease of annual incomes at our subsidiary Chilectra S.A. of about 3,000 million Chilean pesos, starting on 2010.

Sincerely,

Ignacio Antoñanzas Alvear
Chief Executive Officer
