Ref.: Relevant Fact Statement

Dear Mr. Ferreiro:

In accordance with Articles 9 and 10.2 of Law No. 18,045 and the
Superintendency's General Regulation No. 30, I hereby inform you, as a Relevant
Fact Statement, that, today, this Company has been informed that Elesur S.A. has
sold and transferred to Endesa Internacional S.A. 1,778,826,237 shares of
Enersis S.A., representing the 5.448475% of the Company's total capital stock,
at a price of 84.5 Chilean pesos per share. Both companies, meaning Elesur S.A.
and Endesa Internacional S.A. are currently subsidiaries and 100% controlled by
the Endesa Spain Group.

This transference doesn't change at all the control that the Endesa Spain Group
exercises over Enersis S.A., and it has been done as part of the complete
process of rationalization and simplification of the Endesa Spain Group's
corporate structure.

Sincerely yours,

                               Alfredo Ergas Segal
                             Chief Financial Officer
