Ref: ESSENTIAL INFORMATION

Mr. Superintendent:

Pursuant to articles 9 and 10 of the Securities Law No. 18.045, and chapter 18-10 of the Compilation of Regulations of the Superintendency of Banks and Financial Institutions, I do hereby inform you, as an essential information  that on July 9, 2012, according to article 19 of the Chilean General Banking Act, the Superintendency of Banks and Financial Institutions imposed a fine of CLP 40,000,000 (Chilean pesos) to Banco de Chile, in connection with the forwarding and delivering service by electronic mail corresponding to  June 2012 current account  statements.

The aforementioned regulation establishes requirements for banks to maintain  adequate operational risk management to assess the risks involved in outsourced activities and take appropriate mitigation measures. In this regard, banks must ensure that the outsourced services provide sufficient security to  permanently protect the confidentiality, integrity, accuracy and quality of information and data, circumstances that at this time were not met.

In addition, the Superintendent ordered Banco de Chile to enable dedicated attention points to deal with customer inquiries and  submissions in connection with the erroneous forwarding by electronic mail of current account statements to its clients.

Sincerely,

Arturo Tagle Quiroz

Chief Executive Officer
