contracts, on 12/13/2000, the FINANCE AGENTS, BNDES, the CENTRALIZING BANK, CRT and the INTERVENING PARTY JOINT GUARANTOR formalized the COLLECTION AND DEPOSIT AGREEMENT WITH INTERVENTION AND OTHER COVENANTS, whose
purpose was to restrict and pledge in favor of the FINANCE AGENTS and BNDES the revenue from the provision of telecommunication services by CRT to the users, as guarantee of compliance with the obligations assumed in these two
loans. BENEFICIARY, as a result of incorporation, succeeded CRT in these contracts. 
 c) BNDES and BENEFICIARY entered into, on
11/25/2002, the Contract of Supply by Extension of Credit No. 02.2.735.3.1, in the amount of R$97,600,200.00 (ninety-seven million, six hundred thousand and two hundred reais). On the same date, the FINANCE AGENTS, BNDES, the

 II. The FORMER DIRECT AND INDIRECT
LOANS and the respective COLLECTION AGREEMENTS underwent successive addenda, aiming at, among other objectives, the sharing of revenues already restricted to new collection agreements, resulting from new loans already granted. 

III. The COLLECTION AGREEMENTS instrumentalized not only guarantees for the FORMER DIRECT LOANS, but also guarantees provided to the FORMER INDIRECT
LOANS, in which the FINANCE AGENTS onlent funds for the implementation of the same projects contemplated by the transactions executed directly with BNDES. 
 IV. Adding the portions of revenue successively restricted as guarantee as a result of the FORMER DIRECT AND INDIRECT LOANS, it is determined that all the revenues of BENEFICIARY, from the provision of
telecommunication services, and received through COLLECTING BANKS, were assigned in guarantee to BNDES and to the FINANCE AGENTS, defined below. 
 V. The assignment and restriction of the revenues by the BENEFICIARY as a result of the obligations assumed in the FORMER DIRECT LOANS and in new direct loans granted by BNDES will be
governed by the systemization established herein, which deals in a unified manner with the assignments and restrictions of revenues agreed in different loans. This regimentation is agreed upon in order to permit its use as guarantee of new loans and
enable the alteration of the volume of restricted revenues, including with eventual volume reductions.
