In accordance with articles 9 and 10, paragraph 2, under Securities Market Law Nº18,045, and as established under General Norm Nº 30 of the Superintendence, duly authorized on behalf of Empresa Nacional de Electricidad S.A. (the “Company” or “Endesa Chile”), I hereby inform you the following significant event:

Consequently, and as agreed at the ESM, the Company’s Spin-Off takes effect on Monday, February 1, 2016, whereupon the new corporation, Endesa Américas S.A.

As agreed to at the ESM, the Board of Directors of Endesa Américas, will proceed in due time to request the registration of Endesa Américas and its respective shares in the Securities Registry of the Superintendence of Securities and Insurance and in the Stock Exchanges where the shares of Endesa Chile are currently traded. The distribution, and the material delivery of the shares issued by Endesa Américas will take place at a date established by the Board of Directors of Endesa Américas, once the shares registration in the Securities Registry of the Superintendence of Securities and Insurance and Chilean Stock Exchanges are complete, and when the legal and regulatory requirements have been fulfilled.
