This modification shall be materialized through the amendment of the respective clauses of the Deposit Agreement dated November the 27^th, 2001, entered among Banco de Chile and JP Morgan Chase Bank, as Depositary Bank. Such Deposit Agreement and the referred Program will be subject to the exchanges regulations of general application of Chapter XIV of the “Compendium of Foreign Exchange Regulations” issued by the Central Bank of Chile or such new regulations that may be issued in the future. Likewise, as a consequence of the aforementioned,  the Board of Directors resolved to agree with the Central Bank of Chile and with JP Morgan Chase Bank the termination of the exchange regime established by the current Exchange Convention, subscribed under former Chapter XXVI of the mentioned Compendium.

Finally, the Board of Directors agreed to strictly observe all contractual and regulatory provisions, including the notification to the ADRs holders of the modification to the mentioned Program, in order that the ADRs holders are able to exercise within 30 days counted from the date that they were given notice of the rights they have under the Deposit Agreement and under applicable regulations.
