Santiago, December 3, 2009

Mr. Guillermo Larraín Ríos
Superintendent of Securities and Insurance

Ref: ESSENTIAL INFORMATION

Mr. Superintendent:

The Board of Directors of Banco de Chile has agreed to propose to the Extraordinary Shareholders Meeting to be called upon before the next Ordinary Shareholders Meeting, the introduction of a transitory provision to the by-laws of Banco de Chile, in particular, in reference inter alia to articles 24, 25 and 28 of Law N° 19.396, and to the provisions agreed in the Contract dated November 8, 1996, executed between the Central Bank of Chile and Banco de Chile, currently SM Chile S.A., that Banco de Chile’s profits to be distributed will be those resulting from the reduction or increase to the net income, the equity monetary correction adjustment (consumer price level restatement over the equity) and their corresponding variations. This transitory provision will be in effect until the obligation of Sociedad Matriz del Banco de Chile, directly or through its subsidiary SAOS S.A., referred to in law N° 19.396, has been extinguished.

The above described agreement was subject to the consideration of the Council of the Central Bank of Chile, and such entity approved, in ordinary meeting that took place on November 3, 2009, the proposal that the Board of Directors of Banco de Chile will hold before Shareholders meeting.

Sincerely,

Fernando Cañas Berkowitz

General Manager
