SECTION ONE - SUBJECT MATTER

The subject matter of this AMENDMENT is the modification of the terms of the
AGREEMENT, as set forth hereinbelow:

         1.1      The price to be paid by AOL for each Dedicated Modem shall
                  hereafter be: a) [**] per month during the year [**]; (b) [**]
                  per month during the year [**]; and (c) [**] per month from
                  [**] until expiration of the term of this Agreement. Such
                  amounts do not include taxes, which shall be borne by AOL, in
                  accordance with the terms of the Agreement. Such amounts shall
                  be hereafter applicable to all Dedicated Modems already
                  contracted for and to all Dedicated Modems that may be
                  requested by AOL to EMBRATEL as of the date of execution of
                  this AMENDMENT. Such prices shall be effective as of the date
                  of execution of this AMENDMENT.

         1.2      As provided under Section 1.2 (a) of the Agreement, AOL may
                  request the transfer of any Dedicated Modem to any other city
                  where EMBRATEL offers such service. In such case, the price
                  payable for transfer of each Dedicated Modem so transferred
                  shall be [**], without taxes.

         1.3      The contracting for [**] Dedicated Modems in the localities
                  set forth in Annex I shall be cancelled as of the date of
                  execution of this AMENDMENT, the total number of active
                  Dedicated Modems on the date hereof being, therefore, [**],
                  allocated as set forth in Annex II. Cancellation of the
                  contracting for Dedicated Modems, as agreed to herein, will
                  not imply the payment of fines, taxes or penalties by AOL to
                  Embratel.

                  1.3.1      The Parties represent that, out of the total
                             Dedicated Modems contracted for by AOL up to the
                             present date, [**] Dedicated Modems, marked with an
                             (*) in Annex II, have not yet been installed by
                             EMBRATEL. The parties agree, for all purposes, that
                             as of the effective installation of such Dedicated
                             Modems by EMBRATEL, all the provisions contained in
                             this AMENDMENT that are applicable to Dedicated
                             Modems installed before/up to the date of execution
                             of this AMENDMENT shall be applicable to such
                             Dedicated Modems.

                  1.3.2      Because [**] Dedicated Modems have not been
                             installed by EMBRATEL, as referred to under
                             paragraph 1.3.1 above, and without prejudice to the
                             cancellation of the contracting for [**] Dedicated
                             Modems, as agreed under a provision in the head of
                             this Section 1.3, the effective disconnection of
                             [**] Dedicated Modems marked with an (*) in Annex I
                             shall occur to the extent that the Dedicated Modems
                             referred to under paragraph 1.3.1 shall be
                             effectively installed.

                                       2
<PAGE>

                  1.3.3      The Parties agree that no additional sum will be
                             payable, on whatever account, by AOL to EMBRATEL by
                             reason of the installation and effective
                             disconnection of Dedicated Modems as provided under
                             Paragraphs 1.3.1 and 1.3.2 above.

         1.4      The Parties agree to expressly exclude from the Agreement the
                  minimum requirement described in Section 1.1 of the Agreement,
                  concerning the obligation of AOL to contract for a minimum of
                  [**] Dedicated Modems during the term of the Agreement.

         1.5      Without prejudice to the provision under section 1.3 above,
                  during the period between [**] and [**], AOL shall (i) by
                  contracting and/or maintaining the contracted for number of
                  Dedicated Modems, provide a minimum net-of-taxes revenue for
                  EMBRATEL equal to [**]; and (ii) secure a minimum of [**]
                  activated Dedicated Modems every month. In the event the
                  revenue amount of [**] and [**] is not provided by AOL in the
                  aforementioned period, AOL shall pay the difference between
                  the amount effectively paid to Embratel and the amount of
                  [**], such difference to be included in the invoice for
                  services provided in the month of December 2002.

1.6 Notwithstanding any time set in the AGREEMENT and in any amendment thereto,
the term of validity of all of the [**] Dedicated Modems contracted for up to
the date of execution of this AMENDMENT is hereby extended for a term of
thirty-six (36) months from the date of execution hereof.

1.7 The terms of validity of new Dedicated Modems (where "new" shall refer to
Dedicated Modems contracted for after the execution of this Amendment) shall be
as follows:

                  1.7.1 After execution of this AMENDMENT, any and all Dedicated
                  Modems required by AOL from Embratel during the first
                  twenty-four (24) months from the date of execution hereof --
                  for localities where AOL already has Dedicated Modems
                  installed and active on the date of this AMENDMENT -- which
                  result in a total number of contracted for and activated
                  Dedicated Modems that is less than or equal to [**], shall be
                  subject to a term of validity not to exceed thirty-six (36)
                  months from the date of execution of this AMENDMENT.

                  1.7.2 Any and all Dedicated Modems required by AOL from
                  Embratel after the twenty-fifth (25th) month from the date of
                  execution of this AMENDMENT shall be subject to a term of
                  validity of thirty-six (36) months from the date of execution
                  of the respective instrument of amendment whereby the
                  contracting therefor is formalized.

                  1.7.3 After execution of this AMENDMENT, any and all Dedicated
                  Modems required by AOL from Embratel -- for localities where

                           number of remaining, contracted for and activated,
                           Dedicated Modems that is less than [**], but
                           exceeding [**], may be made, provided that AOL pays
                           EMBRATEL a penalty of a compensatory nature in an
                           amount equal to [**] of the total amount of any
                           installments payable by AOL to EMBRATEL with respect
                           to each Dedicated Modem terminated. In the event
                           termination as provided under this letter "c" results
                           in a total number of remaining, contracted for and
                           activated, Dedicated Modems that is less than [**],
                           AOL will pay EMBRATEL a penalty of a compensatory

                           which has been terminated.

                           d) [**], termination by AOL of the contracting for
                           Dedicated Modems -- in the localities where AOL has
                           Dedicated Modems installed and active on the date of
                           execution of this AMENDMENT -- resulting in a total
                           number of remaining, contracted for and activated,
                           Dedicated Modems that is less than [**], but
                           exceeding [**], may be made, provided that AOL pays
                           EMBRATEL a penalty of a compensatory nature in an
                           amount equal to [**] of the total amount of any
                           installments payable by AOL to EMBRATEL with respect
                           to each Dedicated Modem the contracting for which has
                           been terminated. In the event termination as provided
                           under this letter "d" results in a total number of
                           remaining, contracted for and active, Dedicated
                           Modems that is less than [**], AOL will pay EMBRATEL
                           a penalty of a compensatory nature in an amount equal
                           to [**] of the total amount of any installments
                           payable by AOL to EMBRATEL with respect to each
                           Dedicated Modem the contracting for which has been
                           terminated.

                  1.8.2 AOL may individually terminate the contracting for any
                  Dedicated Modems installed in localities where AOL has [**]
                  Dedicated Modem installed and active up to the date of
                  execution of this AMENDMENT, or in localities where the number
                  of Dedicated Modems has been reduced to [**] pursuant to this
                  AMENDMENT. Any such termination will subject AOL to the
                  payment to EMBRATEL of a penalty of a compensatory nature in
                  an amount equal to [**] of the total amount of any
                  installments payable by AOL to EMBRATEL with respect to each
                  Dedicated Modem the contracting for which has been terminated.

         1.10 EMBRATEL warrants that it will provide a continued service, unless
         any restriction /impediment of a regulatory nature with respect to the
         type of service to be provided under the agreement, and the conditions
         for the provision thereof, shall prevent EMBRATEL from providing such
         service.

                  1.10.1 In the event ANATEL establishes final regulations for
                  governing "Material aspects concerning the use of
                  telecommunications services and networks for access to
                  Internet services", which were the subject matter of the
                  Notice for Public Comment (CONSULTA PUBLICA) No. 0372, and in
                  the event EMBRATEL proceeds to provide Internet dialed access
                  service (the subject matter of the AGREEMENT) under such new
                  modes /conditions as may be established by ANATEL, AOL, at its
                  exclusive discretion, may cause the Dedicated Modems then
                  installed and active to migrate to the new mode for the
                  provision of the service, according to new and specific
                  commercial conditions for the provision of such new service,
                  to be negotiated between the Parties upon the implementation
                  thereof, and AOL shall not be subject to any fine, penalty or
                  indemnification by reason of such change in the conditions for
                  the provision of the service.

         1.11 The Parties agree that, as of the execution of an appropriate
         agreement between AOL and EMBRATEL with respect to shared marketing
         investments, Section 10.5 of the AGREEMENT (as modified under the
         amendment 01/2000) will be deemed excluded from the AGREEMENT,
         whereupon all of the effects thereof shall cease.

SECTION TWO - GENERAL PROVISIONS

2.1      The Parties hereby ratify all other provisions under the Agreement and
         amendments thereto, which shall be maintained in their entirety to the
         extent they do not conflict with this AMENDMENT.

2.2      This AMENDMENT binds the Parties, by themselves, their successors,
         heirs and assigns on any account.

2.3      The contracting and cancellation/termination of the contracting for any
         Dedicated Modems, as well as any contractual modification, will only be
         valid if made by an instrument of amendment executed by the authorized
         representatives of both Parties. Nevertheless, a request for the
         transfer of Dedicated Modems, as provided under Section 1.2 (a) of he
         Agreement, may be made by written notice from AOL to Embratel, and such
         request will be deemed valid after being expressly accepted by
         EMBRATEL.

         2.3.1 Embratel shall respond to AOL whether Embratel accepts any such
         request not later than (i) [**], where a transfer shall be made to a
         locality where AOL already has Dedicated Modems; and (ii) [**], where a
         transfer shall be made to a locality where AOL does not have any
         Dedicated Modem yet.

         2.3.2 Absence of any response by Embratel within the time limits
         established herein shall be construed as an express acceptance of AOL's
         request by Embratel.

Intending to be legally bound the Parties execute this AMENDMENT in two (02)
counterparts, before the two (02) subscribing witnesses.
