            4.1.1.1. while the agreement for providing access infra-structure to
            the broad band Internet services in the modality Dial Provider,
            executed between AOL and Telecomunicacoes de Sao Paulo S.A. is in

Telefonica Empresas, and the infra-structure fruition on the part of AOL, and
will provide the necessary investments for complying with the duties which were,
either set forth or arisen from this Agreement.

5. BETTER CONDITIONS

5.1. Neither Telefonica Empresas, nor its Affiliates will offer or provide to
any client, services comparable to the services herein offered with (i)
geographic coverage; (ii) contractual term; (iii) traffic volume in the Web
Channel, equal or lower than that hired by AOL ("Comparable Services") (a) for
prices (net amounts of taxes) which are lower than those charged from AOL, or
(b) in accordance with any terms and conditions which are more favorable to such
client than AOL's terms and conditions (each one of (a) or (b) are the "More
Favorable Terms"). If Telefonica Empresas or any of its Affiliates offers or
provides Comparable Services in More Favorable Terms, to any client, Telefonica
Empresas shall offer AOL such services, under the terms and conditions
applicable to such client. If Telefonica Empresas or its Affiliates offers or
provides services to a client which do not constitute Comparable Services, (such
Services are the "Non-Comparable Services") then, within thirty (30) days
subsequently to that service offer or providing, Telefonica Empresas will offer
AOL such services at the available prices and under the terms and conditions
applicable to that client. If an applicable law or regulation changes in such a
way that this clause requires that Telefonica Empresas performs in a way which
is not allowed, pursuant to this new law or regulation, then this clause shall
be considered re-written so as to reflect, the closest possible, the original
intention of the Parties. Under AOL's request (requirements which shall not be
made more than once per quarter year) the Financial Administrative
Vice-President of Telefonica Empresas shall state, in writing, whether
Telefonica Empresas has complied with the duties set forth in this Clause. If,
concerning the Non-Comparable Services, AOL's service requests need changes in
its terms and conditions, then, the Parties shall work in good faith to adjust
such terms and conditions towards a mutual deal that complies with such
requests.

<PAGE>

                                                                              12

5.2. In case Telefonica Empresas violates one of the duties described in the
above provision, the prices, pursuant to this Agreement, must be immediately
adjusted so as to be either equal or lower than the corresponding prices offered
to other clients and, regarding the payments made by AOL, as set forth by this
Agreement, as of the date when TELEFONICA started the offer for that client, and
the resulting adjustment can be refunded by TELEFONICA, at AOL's discretion, as
credit for future payments or under the form of a single payment within a period
of time that does not exceed thirty (30) days as of AOL's notification of such
violation.

5.3. In the event of material changes in the Market Price, AOL, every six months
counted as of the execution of this instrument, will send mail to Telefonica
Empresas, requesting price adjustment of the Services, so that the latter can
reflect the amount charged for Comparable Services in the market.

      5.3.1. It is understood by "Market Price", the comparative net price
      offered by another company that renders Comparable Services, as defined in
      item 5.1 above, in at least one locality of one of the five geographic
      regions of the Federative Republic of Brazil, and with a contractual term
      and IP traffic volume to be supplied, which are, at least, equal to those
      offered to AOL, pursuant to this Agreement.

            5.3.1.1. The Market Price defined in item 5.3.1 above, cannot be
            considered as a valid price for the purposes of this provision, in
            case it is:

            (i)   a price which is lower than that effectively incurred for
                  providing such Comparable Services;

            (ii)  offered by a company with evident deficit spending and that
                  such price is lower than the price of cost of that same
                  company; or

            (iii) predatory prices, with the intention of damaging or defrauding
                  TELEFONICA's participation in the market, and which are below
                  the actual costs incurred by the company that renders those
                  Comparable Prices.

      5.3.2. TELEFONICA shall be entitled to revise and confirm the validity of
      the proposed Market Price, within a thirty-day term, counted as of the
      receipt of the mail sent by AOL, pursuant to the terms of 3.1. above.

      5.3.3. Subsequently to the acknowledgement of AOL's mail, and provided
      that it is of common concord between the Parties, a specific instrument of
      addendum to the present Agreement can be executed to adjust the Price List
      contained in Exhibit F of the present instrument to the new values.

      5.3.4. In case Telefonica does not validate the market prices suggested by

notification, through a simple written notification to Telefonica Empresas, in
case Telefonica Empresas:

      (i)   subcontracts third parties or transfers to third parties, in the
            whole or in part, its rights and duties arisen from this Agreement,
            without AOL's previous written authorization;

      (ii)  fails to comply with any obligation set forth in this Agreement and

            dissolution ruled, confessed or required.

7.3. Pre-termination of the present Agreement, by AOL, or by Telefonica
Empresas, in any circumstances, including those established in Clauses 7.1 and
7.2 above, shall subject the Party that has given reason for the Agreement
termination, to the payment of compensatory fine to the other Party, within a
thirty-day term, counted as of the termination date, equivalent to [**]
([**]%) of the total remaining value of the present Agreement, calculated on the
grounds of the Price List contained in Exhibit 5. For the purposes of
calculation of such fine, the following formula shall be applied:

F = 0.325 x V x NP x MV, where:

F = fine to be paid by the Party that has terminated the Agreement;

V = Value = Price list per Mbps contained in Exhibit 5;

NP = number on Mbps made available to AOL in the month previous to the
termination month;

MV = number of months still missing until [**].
