Ref: Reorganization – Merger with and into Enel Chile S.A.

Dear Mr. Chadwick,

We hereby refer to the significant event disclosed by Enel Chile S.A. (“ Enel Chile ”) dated November 14, 2017 (“Enel Chile Significant Event ”), by means of which Enel Chile’s Board of Directors, with the unanimous consent of its members, issued a collective pronouncement in favor of the corporate reorganization (the “ Reorganization ”), a related party transaction that involves the following: (i) the merger by incorporation of Enel Green Power Latin America S.A (“ EGPL ”) by Enel Chile that will result in the dissolution of EGPL, being absorbed by Enel Chile, acquiring all assets, liabilities and equity of EGPL and succeeding it in all its rights and responsibilities; (ii) a public tender offer by Enel Chile for up to 100% of the shares and the American Depository Shares (“ ADS ”) issued by Enel Generación Chile S.A. (“ Enel Generación”) held by the minority shareholders of the latter (the “ TO ”). This tender offer will be subject to a series of conditions, including the condition mentioned in the Enel Chile Significant Event regarding the capital increase of Enel Chile that is to be partially paid for with a portion of the price payment of the TO; (iii) a capital increase of Enel Chile required to issue sufficient shares and ADS to be delivered to the Enel Generación shareholders that decide to sell their shares or ADS in the Enel Generación TO and to issue sufficient shares to deliver to EGPL shareholders in the Merger with Enel Chile (the ” Enel Chile Capital Increase ”); and (iv) an amendment to the Enel Generación bylaws (the “ Amendment to Enel Generación Bylaws ”) to eliminate the dispositions of Decree Law N ^o 3,500/1980 related to shareholder concentration. This amendment is established as a condition precedent to the success of the TO.

The Enel Chile Significant Event states that the Reorganization involves all the actions or stages identified above, so that, they must all be approved for the Reorganization to be approved.

Consequently, the Board of Directors’ meeting held November 14, 2017, after analyzing the available information regarding the Reorganization, believes the Merger, within the context of the Reorganization, may be positive for EGPL shareholders because it consolidates the stake in the distribution business (through Enel Distribucion S.A, subsidiary of Enel Chile), the conventional generation business ( through Enel Generación) and the non-conventional generation business (through EGP Latam) into one sole company creating the leading company in the electricity industry; aligns the interests of the common controlling shareholder of these companies, Enel SpA, with the shareholders of Enel Chile; optimizes Enel Chile’s capital structure; and improves the liquidity of the stock. The exchange ratio proposed by Enel Chile is also considered adequate.

Due to the abovementioned, such board of directors’ meeting, with the unanimous consent of its members, agreed to summon an Extraordinary Shareholders Meeting of EGPL. to be held on December 20, 2017, in the main office of the company to pronounce on the following topics:

1) In accordance with the provisions of Article 44 of the Corporations Law N ^o 18,046, approve the corporate reorganization (the “ Reorganization ”) as a related party transaction involving the following actions or stages: (i) the merger by incorporation of Enel Green Power Latin America S.A (“ Enel Green Power ”) by Enel Chile S.A. (“ Enel Chile ”)( the “ Merger ”) that will require a capital increase of Enel Chile to pay for the shares of Enel Green Power shareholders according to the exchange ratio to be determined for the Merger and that is subject to, among others, a successful PTO as mentioned hereafter; (ii) a public tender offer by Enel Chile for up to 100% of the shares and the American Depository Shares (“ ADS ”) issued by Enel Generación Chile S.A. (“ Enel Generación ”) held by the minority shareholders of the latter (the “PTO”) requiring as a condition, among others, that the number of shareholders that accept the PTO allow Enel Chile to reach an ownership share of Enel Generación above 75% and also that such shareholders and ADS holders accept to subscribe shares and ADS, respectively, of Enel Chile issued as part of the capital increase as described hereafter. Such Enel Chile shares and ADS will be paid for with a portion of the price Enel Generación Shareholders receive for selling their shares and ADS in the TO; (iii) a capital increase of Enel Chile (the” Enel Chile Capital Increase ”) to issue sufficient shares and ADS to be delivered to the shareholders of Enel Generación that accept to sell their shares and ADS in the Enel Generación cash tender offer, capital increase that is subject to the success of the TO referred to in numeral (ii), and (iv) an amendment to the Enel Generación bylaws (the “ Amendment to Enel Generación Bylaws ”) to eliminate the limitations and restrictions established by the dispositions of Decree Law N ^o 3,500/1980, particularly, that one shareholder may not hold more than 65% of the shares with voting rights of Enel Generación (the “ Amendment to Enel Generación Bylaws ”) that depends on the success of the TO mentioned in numeral (ii) above.

The Reorganization involves all the actions or stages identified above, so that, they must all be approved for the Reorganization to be approved.

2) In accordance with the provisions of Title IX of the Corporations Law and Title IX of the Corporations Rules, approve: (i) the proposed Merger by incorporation of Enel Green Power by Enel Chile, dissolving it without the need of a liquidation and succeeding it in all its rights and responsibilities;(ii) the exchange ratio of the Merger; (iii) the audited financial statements of Enel Chile and Enel Green Power as the companies involved in the merger; (iv) Enel Chile’s bylaws as the surviving entity of the merger; (v) the respective expert report; and (vi) the document entitled “General Terms of the Reorganization”.

Regarding Article 155 of the Corporations Law, the information referred to by Enel Chile’s Significant Event has been made available to its shareholders and also to the shareholders of EGPL on the website www.enelgreenpower.com/es/pais-chile.html.

3) Adopt all agreements that are necessary and conducive and/or convenient to legalize, materialize and give effect to the decisions adopted by the Shareholders’ Meeting.

The board of directors of EGPLhas agreed that the undersigned deliver this document to you and authorizes its disclosure to Enel Chile’s shareholders and the general public.

Sincerely,

James Lee Stancampiano

Chairman of the Board of Directors

Enel Green Power Latin America S.A.
