Assignment and Pledge of Incomes Agreements

All of the Credit Facilities are secured by the Assignment and Pledge of Incomes Agreement entered into by and among the Company and BNDES on August 13, 2004 (as amended on November 14, 2006 and January 9, 2008), which
provides that the income from the telecommunications services rendered by the Company to its users will be deposited in a pledged account in order to secure the obligations under the Credit Facilities.

On August 8, 2004, BNDES, Banco do Brasil S.A., Banco Itaú S.A., the Company, 14 Brasil Telecom Celular S.A. and Brasil Telecom Participações S.A. entered into an Assignment and Pledge of Incomes Agreement, in which the Company assigned and pledged as security to BNDES its incomes in the fixed amount of
R$442 million. Such amount corresponds to the sum of the greater of the following parameters, to be accrued for each of the financings: (i) 25% (twenty-five percent) of the respective debt amount; or (ii) the sum of the amortization installment
of the main debt, due over the next 6 months. On November 16, 2006, this agreement was amended to extend to Credit 06.  Finally, on January 9, 2008, the agreement was amended again to extend to Credit 07.

The amounts deposited in the pledged account may be blocked through communications between BNDES and the Banco Itaú S.A., in the case of default under any financial obligation, a breach of any financial covenant,
or certain other breaches of the Credit Facilities.

The Company agreed not to assign, bind, cede, transfer, sell, burden, pledge, bond, or, in any way negotiate the pledged incomes, or to grant any right to any other creditor with respect to the pledged collateral
account without the express prior consent of BNDES, under the penalty of early acceleration of the financing agreements.

All of the agreements mentioned above are also subject to the General Provisions applicable to BNDES agreements, established by BNDES Resolution no. 665/87.

Events of Default

All of the Credit Facilities are subject to events of default which may lead to termination of the Credit Facilities.

According to Articles 39 and 40 of the BNDES agreements, BNDES may declare the early maturity of an agreement and immediately demand the debt upon the occurrence of: (i) default of any obligation by the Company or by Brasil Telecom Participações S.A.; (ii) cross-default of any company belonging to the same economic group of the Company, under other agreements entered into with BNDES or any of
its subsidiaries; (iii) effective, direct or indirect change of control of the Company, without the express prior consent of BNDES; or (iv) legal proceeding or any event adversely affecting the security tendered in favor of BNDES.
