With the Agreement of Mutual Exoneration, the disputes involving the Companies and their subsidiaries and the companies in the Telecom Itália group, among others, will end, including the arbitrations mentioned in the Notice sent by the Companies on March 16^th, 2006.

The effective acquisition of Brasilco Shares, which is subject to the approval of the National Agency for Telecommunications – ANATEL and other conditions, will allow for the end of the existing administrative actions regarding the overlapping of telephony licenses (Fixed-Line Telephone Service – STFC, Personal Mobile Service – SMP, National Long Distance – LDN, and International Long Distance - LDI) among companies of the Brasil Telecom and Telecom Itália groups, thus eliminating potential adverse material effect to the business and interests of the companies within the Brasil Telecom group.

The Companies wish to clarify that they are not parties to the Purchase Agreement relating to Brasilco Shares, nor to any other agreements that may have been signed simultaneously in connection with the Agreement of Mutual Exoneration.
