Annex “C”

Principles of Interaction for Off-Shore Business

a) Business Units:

- “Banca Personas Internacional” of Banco de Chile (hereinafter, “IPB BCH”): Based in Chile, its main function shall be to coordinate the interaction with Citi IPB US business.

- “Citi IPB US” of Citigroup (hereinafter “Citi IPB”): Based in the United States, it shall have as its main function to directly manage and take care of the relationship (products and services) of the Relevant Customers.

b) “Relevant Customers”: They are the customers with a relationship established with Citi IPB and are segmented as follows:

- “ Existing Citi IPB Customers”: They are those existing customers in Citi IPB before January 2008.

- “ Citi IPB Ex BCH USA Customers”: These are those customers currently existing in Citi IPB who belonged to branches of Banco de Chile in the United States (New York and Miami) and who were acquired by Citigroup through the Asset Purchase Agreement.

- “New Citi IPB Customers”: They are those customers (i) existing in Citi IPB and referred by Banco de Chile as of January 2008, and (ii) those that are referred in the future by Banco de Chile.

In order to identify the Relevant Customers, the Parties have compiled a list that they shall keep updated with incorporations (new relationships) and deletion (desertion) for each segment.

For purposes of the Annex “B-1” of the Connectivity Agreement, the concept “new Chilean Customers of IPB products (those not included in the lists of original RUTs [Tax IDs] )” means the New Citi IPB Customers of this Annex C.

c) Distribution Network Banco de Chile: It consists of various channels (retail banking businesses, wholesale banking businesses, subsidiaries (including Banchile Inversiones), etc.) with the ability to generate referrals to Citi IPB. This shall take place through the executives of the aforementioned channels or through centralized actions that are carried out (Product and/or Marketing of the Bank).

d) Targets: Targets for the above-mentioned benchmarks shall be established annually and jointly and shall be monitored (jointly by both parties) to adjust and implement the necessary action plans in case of significant deviations.

e) Platform (products and services): Citi IPB should use its reasonable best efforts to provide a competitive platform for costs, products, services, and level of care. This, in order to provide a competitive offer that allows Banco de Chile to generate the level of referrals in the manner agreed, to minimize the attrition of Relevant Customers, and allowing to assess the use of the Citi IPB platform by other units of Banco de Chile (e.g., Banchile Inversiones) with a similar offering.

f) Customer Relations:

- Citi IPB, from the United States, shall be responsible for managing the relationship of the Relevant Customers in all its aspects, through a level of service and contact in line with the standards according to the profile and relationship balance in Citi IPB.

- In addition to generating referrals to Citi IPB, Banco de Chile shall provide certain services of assistance in the interaction between the Relevant Clients and Citi IPB, which shall be documented in the Interaction Model (as defined in subparagraph (j) of this Annex C).

- Travel to Chile or visits to customers in Chile by representatives of Citi IPB must be previously agreed, and coordinated with Banco de Chile, and shall be governed by the protocols defined with Banco de Chile and with observance of the applicable law.

- Citi IPB shall not be authorized to prospecting Chilean customers without the approval of Banco de Chile.

- With regard to customers referred to Citi IPB by Relevant Customers, Citi IPB must inform Banco de Chile, and they shall become a part of the New Citi IPB Customer base.

- IPB BCH shall coordinate with Citi IPB to: (i) monitor the evolution of the business and the defined targets of referrals; (ii) carry out the referrals processes (iii) collaborate with Citi IPB in aspects that require local management and reactive scope (at the request of Citi IPB and prior agreement of BCH) and limited to matters related exclusively to the administrative care of clients (e.g. approval of Public Figures, Legal Opinions). All activities related to investment products are excluded from the collaboration.

g) Measurements: On a quarterly basis, Citigroup shall inform Banco de Chile of the revenues obtained by Citi IPB from New Citi IPB Customers, and Banco de Chile shall report the aggregate costs of IPB BCH, to generate the respective invoicing and payments, within the month immediately following the corresponding quarter, and according to the provisions of Annex “B-1” of the Connectivity Agreement. The Parties in good faith agree to establish the necessary mechanisms to validate the information generated.

h) Although IPB BCH shall report hierarchically within Banco de Chile, by its nature, there shall be a coordination with Citi IPB, which under no circumstance shall be a functional or direct reporting dependency.

i) It is the intention of the Parties that both the business of Citi IPB and the business of products and services of Banco de Chile grow, and in this sense the coordination for the crossing of products and sales is essential.

j) The Parties shall agree on a document (the “Interaction Model”) detailing the services necessary to enable them to conduct the business under this Annex C in an efficient manner. Such document shall be framed within the parameters and guidelines contemplated in the Connectivity Agreement and this Annex C. The agreement whereby the Parties agree on the Interaction Model and/or its potential modifications shall not require modification of the Connectivity Agreement, Annex C, or any annex to the latter.
