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.
