CHAPTER XIII - PROTECTION OF THE ECONOMIC SITUATION OF CARRIER AND REVISION OF
TARIFFS

      CLAUSE 13.1. A basic presupposition of this Agreement is the preservation,
in the broad competition system of fair equivalence among the provision and
remuneration, the parties being prohibited unjustified enrichment at the expense
of the other party or of service users, pursuant to the terms provided for in
this Chapter.

      SECTION 1. The Carrier will not be obliged to bear losses as a result of
this Agreement, except if they result from some of the following factors:

      I - their negligence, ineptitude or omission in exploiting the service;

      II - risks normal to the business activity;

      III - inefficient management of their business, including that which is
      characterized by the payment of operating and administrative costs
      incompatible with the parameters verified in the market; or

      IV - their incapacity to take advantage of market opportunities, including
      with respect to expansion and increase of the service provision
      contemplated in this license.

      SECTION 2. Unjustified enrichment by Carrier resulting from the following
is prohibited:

<PAGE>

      I - appropriation of economic gains not arising directly out of business
      efficiency, especially when resulting from the publication of new rules on
      the service; and

      II - transfer of revenues to third parties, at the expense of the
      application of the tariff mode principle, as established in Section 7 of
      Clause 6.1.

      SECTION 3. Carrier will be entitled to resume its initial status of
charges and retributions when circumstances of force majeure or calamities
significantly affect the exploitation of the service, always in compliance, as a
parameter, the reflex of these situations on private service providers.

      SECTION 4. In assessing the appropriateness of the resumption covered by
the previous paragraph, among other factors, the existence of coverage of the
event that motivated the change in the initial economic situation by the
Insurance Plan contemplated in Clause 24.1 will be considered.

      CLAUSE 13.2. The resumption of the Agreement's economic situation will be
acceptable when it is demonstrated that the factors indicated in Section 1 of
the previous clause did not occur. This will be done preferably by revising the
rates or by any other mechanism, which, at the discretion of Anatel, is
considered appropriate to neutralize the situation verified.

      SECTION 1. The revision of rates will remove any other neutralization
mechanism of unjustified enrichment of the parties, overcoming the event to
which it referred.

      SECTION 2. Only one, complete and final measure will be adopted to
neutralize a distortion, with respect to the event that produced it.

      CLAUSE 13.3. Regardless of the provisions of Clause 13.1, the revision of
the rates that integrate the Local Service Basic Plan in favor of Carrier or the
users will be appropriate, pursuant to the terms of Article 108 of Law 9.472, of
1997, when one of the following specific situations is verified:

      I - unilateral modification of this Agreement, imposed by Anatel,
      representing an expressive variation of costs or revenues, for more or
      less, so that the increase or reduction of rates is imposed by the need to
      avoid unjustified enrichment by any of the parties;

      II - change in the tax order subsequent to the execution of this
      Agreement, which leads to an increase or reduction in Carrier's potential
      profitability;

<PAGE>

      III - supervening occurrences, arising from the fact of the principal or
      Administration resulting, with evidence, on alteration of Carrier's costs;

      IV - specific change in the law, causing a direct impact on Carrier's
      revenues so as to affect the continuity or quality of the service
      provided; or

      V - legislative change leading to a benefit to Carrier, including that
      which grants or suppresses an exemption, reduction, discount or any other
      tax or tariff privilege, according to the provisions of Section 3 of
      Article 108, Law 9.472, of 1997.

      SECTION 1. The loss or reduction of Carrier's gains resulting from free
exploitation of the service under competitive conditions or conditions of
inefficient management of its own business will not lead to revision of rates.

      SECTION 2. The event of revision contemplated in item II of the heading of
this clause will not apply when the change in the tax order leads to the
creation, suppression, increase or reduction in taxes applicable to the income
or profit or Carrier, such as Income Tax, which do not lead to administrative or
operating liens.

      SECTION 3. There shall be no revision of rates in the events contemplated
in this Clause when the events that led to it have already been covered by the
Insurance Plan contemplated in Clause 24.1.

      SECTION 4. Carrier's contributions to the Universalization Fund of
Telecommunication Services (Fundo de Universalizacao dos Servicos de
Telecomunicacoes) and to the Telecommunications Technological Development Fund
(Fundo para o Desenvolvimento Tecnologico das Telecomunicacoes) will not lead to
revision of rates.

      CLAUSE 13.4. The revision of tariffs will not be appropriate when it is
characterized that the impacts that motivated Carrier's request can be
neutralized by efficient exploitation of the service, by market expansion or by
the generation of alternative or complementary revenues associated to the
purpose of this Agreement, in compliance with the competitive conditions
verified at the time.

      SOLE SECTION . The reduction of revenue resulting from discounts or
reduction of rates will not lead to revision thereof.

      CLAUSE 13.5. The rates revision procedure may be initiated by Carrier's
requirement or by Anatel's determination.

      SECTION 1. When Carrier initiates the rates revision procedure, the
following requirements must be complied with:

<PAGE>

      I - be accompanied by technical or expert report, demonstrating clearly
      and convincingly the occurrence's impact on the formation of the rates or
      on the estimate of Carrier's revenues;

      II - be accompanied by all the documents necessary to demonstration of the
      acceptance of the claim;

      III - Carrier shall indicate its intention to review the rates, informing
      the impacts and eventual alternatives of balancing rates; and

      IV - Carrier shall bear all costs with diligences and studies necessary to
      full instruction of the request;

      SECTION 2. The procedure of rates revision initiated by Anatel shall be
communicated to Carrier, consigning a deadline for latter's pronouncement,
accompanied by a copy of the reports and studies conducted to characterize the
situation that led to the revision.

      SECTION 3. The rates revision procedure will be concluded within a period
not longer than 120 (one hundred and twenty) days, except in case its extension
is necessary to complement the instruction.

      SECTION 4. Anatel shall have to approve the requirement, and Carrier must
provide ample disclosure of new maximum amounts for the revised tariffs,
pursuant to the terms stated herein.

CHAPTER XIV - ALTERNATIVE, COMPLEMENTARY AND ACCESSORY REVENUES

      CLAUSE 14.1. Carrier may obtain other alternative sources of revenues,
provided that this does not lead to failure to comply with the rules set forth
in the Telecommunication Services Regulations and other rules edited by Anatel.

      SOLE PARAGRAPH. In compliance with the terms of the regulations, Carrier,
its associated companies, subsidiaries or controlling companies may not subject
the offer of the service licensed herein to tied consumption with any other
service, or offer benefits to the user by virtue of the enjoyment of additional
services to that contemplated herein, even if provided by third parties.

      CLAUSE 14.2. Anatel may determine that Carrier offers to users provisions,
conveniences or utilities related to the purpose of the license. In this case,
the parties must adjust the unit prices of these services, in compliance with
market parameters and the right to fair remuneration.

      fully amortized by the exploitation of the services, deducting moreover
      the value of the damages caused and of the fines applied, as well as, when
      applicable, the financial obligations not met.

      In August 2001, 15 fixed-line telecommunications carriers that provided
services in 15 states of Region I were merged into Telecomunicacoes do Rio de

Region I covered by them, we have, for ease of reference, filed only the

      In August 2001, 15 fixed-line telecommunications carriers that provided
services in 15 states of Region I were merged into Telecomunicacoes do Rio de
Janeiro S.A., or Telerj, the sixteenth carrier of Region I from the state of Rio
de Janeiro whose legal successor is Telemar Norte Leste S.A., or Tmar. See "Item
3. Key information-Effects of corporate reorganization" and "Item 4. Information
on the Company-Our history and development-Corporate reorganization." Because of
the historical existence of 16 fixed-line telecommunications carriers in Region
I, we have 16 separate agreements with Anatel in connection with certain
services of our telecommunications concession in Region I. As these agreements
are identical in every case except for their reference number and the name of
the concessionaire (in each case, each of the former 16 state fixed-line
telecommunications carriers), we have, for ease of reference, filed only the
relevant concession agreement executed with Telerj and have provided this
schedule to indicate the other concession agreements that we have omitted from
filing as exhibits to the Annual Report on Form 20-F of Tele Norte Leste
Participacoes S.A., or TNL, for the fiscal year ended December 31, 2005.
