June 23, 2011: the SVS was informed that the Company’s board, on June 22, 2011 agreed to call an extraordinary shareholders meeting for June 27, 2011 at 10 a.m. to renew the members of the board through their revocation and election of a new board. This was in consideration of the fact that there had been an important change in the ownership of the subsidiary Aguas Andinas S.A. following the sale of 1,834,539,519 shares held by Corporación de Fomento de la Producción, representing 29.98% of the share capital of Aguas Andinas.

The SVS was informed that the Company’s board had agreed unanimously to call an ordinary shareholders meeting for April 27, 2011, at 10 a.m. at Av. Presidente Balmaceda N° 1398, 10th floor, Santiago, to know and resolve on the matters appropriate to an ordinary shareholders meeting.

The SVS was informed that, as reported to the SVS as reserved information on December 23, 2010, its subsidiary Aguas Andinas S.A. had held discussions with the company AES Gener S.A. (Gener) with respect to Gener’s hydroelectric project called Alto Maipo (hereinafter the Project). On March 29, the board of Aguas Andinas S.A. approved the terms of an understanding with Gener regarding the Project, which would be formalized in one or more contracts signed between Gener and a subsidiary of Aguas Andinas S.A.

The principal matters forming part of this agreement are:

• To ensure that Aguas Andinas continues to use without restrictions the El Yeso reservoir and the associated water rights in order to meet its obligations as concession-holder for the production of water to supply the Metropolitan Region.
• To guarantee it will continue to extract water stored in the El Yeso reservoir at the foot of its dam as before, in such a way for Gener to be able to use this in the exercise of the non-consumptive water rights related to the Project.
• To provide Gener, for its non-consumptive use in the Project, a flow of at least 2.5 cubic meters of the waters received from the lakes Negra and Lo Encañado, with the obligation of Gener to return waters upstream of the independent sluice.
• Regulations referring to the form for using the duct projected which will connect the El Yeso reservoir with the Lake Negra aqueduct in cases of cloudiness or contamination of the waters or their surpluses.
• The form of use of properties with respect to which Aguas Andinas S.A. has easements and assignments of mining concessions related to the Project.
• Payments by Gener for the obligations assumed.
• Guarantees of Gener with respect to the payments mentioned (bank performance bond).
• Functioning protocols in the phases of construction and operation of the Project.
• Term of the agreements, i.e. 40 years.

In economic terms, the payments the subsidiary would receive once the Project is operating (estimated by Gener for the years 2015 and 2016), would vary according to the hydrology of the year and the cost of electricity. It was expected that the respective agreements between Gener and the subsidiary of Aguas Andinas S.A. would be signed in the following six months.

The SVS was informed that the board of the Company on that date agreed to distribute the sum of Ch$16,343,500,000 against the earnings for 2010, as an interim dividend. The Company’s interim dividend No.15 therefore amounted to Ch$16.3435 per share and was payable from November 24, 2010.
