CLAUSE ONE: PURPOSE

1.1   The purpose of this AGREEMENT consists of the services rendered by the
      CONTRACTED PARTY listed in Annex I, which forms an integral and
      inseparable part hereof. Due to the technical differences imposed by the
      specific characteristics of the products offered to the CONTRACTING
      PARTIES, each service rendered by the CONTRACTED PARTY will be covered by
      a "Description and General Conditions of the Services Rendered" that will
      include Services Chart, Price, General Characteristics, Performance
      Ratings (SLA), which consists of one or more pages, all of which
      constitute Annex I mentioned above.



      1.1.1 The CONTRACTED PARTY will render all and any of the services listed
            in Annex I described above only when requested to do so by either or
            both of the CONTRACTING PARTIES, which may occur, as stressed by the
            Parties, through either a direct contract or a competitive bidding
            procedure organized by the CONTRACTING PARTIES. Nevertheless, the
            CONTRACTED PARTY will start to render any of the services listed in
            Annex I only when a "Service Order" is issued by the CONTRACTING
            PARTIES, whose model is given in Annex II, which also forms an
            integral and inseparable part of this AGREEMENT.

      1.1.2 The CONTRACTED PARTY hereby confirms its capacity to perform all and
            any service that the CONTRACTING PARTIES may require therefrom,
            based on Annex I or other descriptions of new services that may be
            produced by the Parties and included herein. Should the CONTRACTED
            PARTY fail to meet the demands of the CONTRACTING PARTY up to the
            limit of its stated capacity within the stipulated period, this will
            constitute a default on the contract, with the CONTRACTED PARTY
            being subject to the penalties stipulated herein.

CLAUSE TWO: APPLICABLE DOCUMENTATION

2.1   For all purposes of Law, the documents listed below are applicable to this
      AGREEMENT as though transcribed below, whose contents are known to the
      Parties, and fully accepted thereby:

CLAUSE THREE: OBLIGATIONS OF THE PARTIES

3.1   During the normal, regular progress of this AGREEMENT, as well as all and
      any services that may arise therefrom, the Parties hereby agree to keep a
      channel of communication always open, allowing them to interact in their
      common interests, reflected through obtaining the expected technical,
      commercial and financial results.

3.2   The Parties agree to fully respect the Clauses and items of this
      AGREEMENT, in addition to the Annexes forming an integral part hereof, the
      Deeds of Amendments that may be signed and the respective autonomy and
      independence related thereto.

3.3   The Parties agree to appoint the persons who will be in charge of managing
      this AGREEMENT, which should be undertaken through written or electronic
      correspondence within 15 (fifteen) days as from the signature hereof. All
      and any correspondence relating to this AGREEMENT should be addressed to
      the Managers to be appointed by the Parties.

3.4   In case of any doubt and / or conflict regarding the interpretation of any
      Item or compliance with any obligation, the Parties should attempt to
      resolve the outstanding matter on a friendly basis through the Service
      Managers to be appointed in accordance with Clause 3.3 above. Should they
      fail to reach an agreement, they should seek a solution through moving up
      the decision-taking scale of the companies, progressing from the Directors
      and Officers to the CEOs and Presidents, in order to reach a non-litigious
      solution. Finally, should it not prove possible to settle such outstanding
      matter, the Parties should opt for arbitration as stipulated in Clause
      Twenty Five of this AGREEMENT.

                  undertake the maintenance, reverse engineering, decompilation
                  or any other act that might affect such data processing
                  programs, unless specifically authorized in advance to do so
                  by the CONTRACTING PARTIES, fully preserving the rights
                  thereof under penalty of bearing the costs of the losses to

                  of this AGREEMENT, and provided that the sole liability of the

8. REDUCTION OF SERVICE

The Parties hereby agree that the CONTRACTING PARTIES may reduce one or all of

                                      A-40


revenues posted over the past 12 (twelve) months by the CONTRACTED PARTY for
this product. When such reduction exceeds [*****], the additional amount will be
considered as partial rescission, being subject to a rescissory fine in such
case equivalent to the amount corresponding to the amount by which the monthly
revenues are reduced, multiplied by [*****]. This amount should be calculated
without including the [*****] reduction permitted as described above, taking
into consideration only the amount exceeding the reduction limit allowed for the
CONTRACTING PARTY. The fine should be paid by the CONTRACTING PARTY reducing the
services requested from the CONTRACTED PARTY, both adopting this stance and
taking the proportional aspects of the revenues into consideration.

4.    BILLING

      4.1.  Variable Remuneration Calculation Model

            4.1.1. Retail: The variable remuneration calculation takes place
                   through weighting the following variables:

              4.1.1.1. Reversal of Billing Harvest:

                  -     The Billing Harvest is defined as the set of all overdue
                        bills, as specified in Items 2.1.1 and 3.0, forwarded by
                        the CONTRACTING PARTY and inloaded by the CONTRACTED
                        PARTY, whose due dates refer to a specific billing month
                        of the CONTRACTING PARTY.

                  -     The CONTRACTING PARTY will remunerate the CONTRACTED
                        PARTY at 0.94% (zero point nine four per cent) of the
                        amounts recovered on the bills forwarded by the
                        CONTRACTING PARTY for collection by the CONTRACTED
                        PARTY.

                  -     The annual target set for the CONTRACTED PARTY is 88.0%
                        (eighty eight per cent) of the reversal of the bills
                        paid up to 90 (ninety) consecutive days in arrears on
                        the amount to be collected through the Billing Harvest
                        (called the "roll-over fee"). This percentage is broken
                        out each month as agreed between the Parties. Depending
                        on the collections performance in terms of this target
                        for the "roll-over fee" (88.0%), the remuneration of the
                        CONTRACTED PARTY will increase or decrease as described
                        below:

                                The CONTRACTING PARTY will pay additional
                                remuneration consisting of 0.25% (zero point two
                                five per cent) for each 0.88% (zero point eight
                                eight per cent) over the percentage target of
                                the "roll-over fee" agreed to between the
                                Parties (88.0%). The same will occur for the
                                remuneration reduction indicator, using a
                                percentage of 0.08% (zero point zero eight per
                                cent) for each 0.88% (zero point eight eight per
                                cent) that the CONTRACTED PARTY performs below
                                target (88.0%).

                  -     There is also a step-up or step-down for the basic
                        monthly amount of the Billing Harvest of R$ 420 million
                        (four hundred and twenty million Reais) in collections.
                        For a variation of more than 1% (one per cent) of this
                        volume, 0.025% (zero point zero two five per cent) will
                        be added to the basic remuneration rate. For a variation
                        in volumes of less than 1% (one per cent), the basic
                        remuneration rate will be reduced by 0.025% (zero point
                        zero two five per cent). The threshold for the Billing
                        Harvest value is R$ 400 million (four hundred million
                        Reais), with no remuneration reduction index above this
                        volume.

                                      A-45



              4.1.1.2. Cancellation of Terminals:

                  -     Monthly terminals removed target as agreed periodically
                        among the Parties.

                  -     Bonus of R$ 10.00 for each terminal not cancelled (over
                        target), with the maximum bonus level being 10% (ten per
                        cent) above target.

                  -     Penalty of R$ 5.00 (five Reais) for each terminal
                        cancelled above target, with the penalty ceiling being
                        15% (fifteen per cent) above target.

GENERAL CHARACTERISTICS:

1.  Attendance Position (PA)

      The period for implementing the resized new services will depend on the
      technical resources required and the length of time needed to recruit and
      train the Human Resources, specifically for each service required by the
      CONTRACTING PARTY, which should be agreed among the Parties.

      For the current services, the implementation period of this resizing
      process should comply with the duration (in hours) of the Training
      Sessions stipulated for each contracted service.

      In view of the possibility of the CONTRACTED PARTY providing customer
      services through additional Attendance Positions (PAs), the Parties will
      agree on such increase, in addition to alterations to the price thereof,
      providing collateral covering the amounts due as payment thereon.

      In order to handle any possible future campaigns, whose dates should be
      notified by the CONTRACTING PARTY, the increase in the stipulated number
      of Attendance Positions (PAs) should always comply with the availability
      of the site(s) being requested by the CONTRACTED PARTY with advance notice

      Holidays, and with advance notice of 15 (fifteen) days for operations on
      business days. It is hereby established that such periods may be altered
      through common agreement between the Parties.

      The period for contracting the Attendance Positions (PAs) that will be
      included in the services may not be less than 30 (thirty) days.

      Any reduction in the Attendance Positions (PAs) should be requested by the
      CONTRACTING PARTY with advance notice of 15 (fifteen) days and may not
      exceed the 10% (ten per cent) monthly average quantity of Attendance
      Positions (PAs) established for these services, with it being hereby
      agreed that the Parties may concur on a shorter period and / or alteration
      to the above percentage, should this be possible for the Customer Service.

      Should the reduction in the Attendance Positions (PAs) requested by the
      CONTRACTING PARTY result in a fraction, it is hereby agreed that this will
      correspond to the full unit higher than such fraction.

                  Attendance Positions (PAs) logged on during the 48 x -1/2
                  hours of the day, divided by 12 (number of intervals worked by

      comply with the provisions in Item 4.4 of this Annex.

                                      A-64


      4.4.5. For Capacity-Building purposes, the training times allocated to
      topics and priorities as defined by the Monitoring and Satisfaction
      Surveys Ratings will be taken into consideration, ensuring that the
      duration thereof is assigned to subjects ranked as high priority.

      4.4.6. The Parties should agree on the duration (in hours) of the
      Capacity-Building Training Sessions, required for special responses and
      new services.

      4.4.7. The CONTRACTED PARTY should schedule the Training Sessions in
      compliance with the operator workloads, so that the service standards are
      not adversely affected thereby, necessarily sized to the scale of the
      operator capacity-building and training schedules.

      4.4.8. The CONTRACTED PARTY should forward the training and
      capacity-building schedule for each site to the CONTRACTING PARTY on a
      monthly basis, with information on the services covered by the Training
      Sessions, the number of operators to be trained, duration (in hours), and
      the location of the Training Sessions.

      4.4.9. The CONTRACTED PARTY should forward to the CONTRACTING PARTY a
      Monthly Training and Refresher Training Control Report covering the last

4.5. Additional Training Sessions

      a. For Training Sessions not covered in Items 4.3 and 4.4, the CONTRACTING
      PARTY should draw up a training schedule for the Multiplicatory Agents,
      lasting no more than 10 (ten) days, to be delivered to the CONTRACTED
      PARTY with advance notice of 2 (two) days prior to the start of the
      Training Sessions. The CONTRACTED PARTY should ensure that its
      Multiplicatory Agents are available, provided that they are not involved
      in other Training Sessions.

      b. The CONTRACTED PARTY should draw up the Operator Training Program with
      the objective of implementing the effective rendering of the services
      within no more than 15 (fifteen) days, as from the end of the
      Multiplicatory Agent Training Sessions.

      c. Should the CONTRACTING PARTY request a Training Plan that requires
      overtime or unforeseen outlays, such outlays will be for the account
      thereof, with such amounts being estimated and agreed among the Parties
      prior to the start of the Training Sessions.

      d. Should the Operator Training Program exceed 10 (ten) days, the
      CONTRACTING PARTY should draw up a training schedule that does not
      adversely affect the Performance Ratings (SLA) of the operations.

5. DURATION

The services listed in this chart will be supplied for a period of 5 (five)
years. On expiry of this period, the supply of the services will be
automatically renewed for 5 (five) years, unless any of the Parties

                                      A-65


decide otherwise. Should any of the Parties decide not to extend the Contract,
the Party adopting such decision should notify the other with advance notice of
180 (one hundred and eighty) days, all as stipulated in Item 14.1 of the
Services Agreement regulating the business relationship in question.

6. REDUCTION OF SERVICE

The Parties hereby agree that the CONTRACTING PARTIES may reduce one or all of
the services constituting this product called "Corporate", rendered by the
CONTRACTED PARTY, provided the respective impact thereof does not result in an
annual reduction of more than [*****] of the revenues posted over the past 12
(twelve) months by the CONTRACTED PARTY for this product. When such reduction
exceeds [*****], the additional amount will be considered as partial rescission,
being subject to a rescissory fine in such case equivalent to the amount
corresponding to the amount by which the monthly revenues are reduced,
multiplied by [*****]. This amount should be calculated without including the
[*****] reduction permitted as described above, taking into consideration only
the amount exceeding the reduction limit allowed for the CONTRACTING PARTY. The
fine should be paid by the CONTRACTING PARTY reducing the services requested
from the CONTRACTED PARTY, both adopting this stance and taking the proportional
aspects of the revenues into consideration.

ARU: Audible Response Unit

2 -- SIZING

2.1 - The Average Attendance Time (TMA) and Calls Forecast used to size the
number of Attendance Positions (PAs) and Customer Care Representatives (RAs)
required to render the services should be drawn up for a three-month period on a
month by month basis, and forwarded to the CONTRACTED PARTY 45 (forty five) days
prior to the first month covered by the Quarterly Forecast.

2.2 -- The CONTRACTING PARTY should draw up the Quarterly Forecast and submit it
CONTRACTED PARTY for its information and agreement within 5 (five) business
days.

2.3 - For the purposes of billing the number of Attendance Positions (PAs) and
Customer Care Representatives (RAs) required for the current month, only the
first month of the quarter is valid.

3 -- BILLING

3.1 - Billing for the Attendance Positions (PAs) - unit price for the "Basic
Infrastructure" as stipulated in the Price List, multiplied by the total number
of Attendance Positions (PAs) calculated through the specific Report taken from
the Traffic Control System (CMS).

Individual calculations will be carried out for the Billing based on the lowest
value between two types of calculation, in compliance with the following rules:

- -     Different operations located on the same floor of a building will be
   charged by the sum of the Attendance Position (PA) Tables logged on each
   half-hour, subsequently checking the MAXTOP value. This calculation will be
   based on business days when the Customer Care Representatives (RAs) are not
   on holiday, defined below for each operation:

            -     Mixed - Monday - Friday

            -     Support - Monday - Friday

            -     Dealer - Monday - Friday

            -     VIP - Monday - Friday

            -     Back Office - Monday - Friday

            -     Welcome - Monday - Friday

IMPORTANT: This calculation should include the Attendance Positions (PAs)
(Infrastructure) assigned to the Customer Care Representatives (RAs) and shared
with another operation remunerated through the Speaking Time model.

- -     Operations not located on the same floor of a building will be handled
      through

                                     A-126


      individual analyses and the sum of the operations. The total value of the
      Attendance Positions (PAs) for Billing purposes will be calculated on the
      basis of the MAXTOP sum, with the optimization of the Attendance Positions
      (PAs) permitted only for Groups of 15 x 15 positions.

   Example:



           OPERATION 1     OPERATION 2    OPERATION 1+ 2
                                 
12h            40              100             140

12:30h         55              130             185

13h            60               80             140

13:30h         50              100             150

14h            30               80             110


      -     For maximum optimization, the total number of Attendance Positions
            (PAs) to be invoiced would be 185.

      -     For the model where maximum optimization is not possible, the
            Attendance Positions (PAs) will be broken down into Groups of 15 x
            15.

            Hypothetical Situation: for the 12:30h interval, there will be an
            overrun of 10 (ten) Attendance Positions (PAs) that will be
            remunerated.

            Calculation:

            Additional Attendance Positions (PAs) = result of dividing the (Sum
            of Operations - Operation 1 or 2) by 15.

            Demonstration: (185 - 130) = 55 / 15 = result of 3, with 10 left
            over.

            Total Attendance Positions (PAs) for Billing = 185+ 10 = 195

            The Billing will be for 190 Attendance Positions (PAs), representing
            the mean between 185 (Operations 1 + 2) and 195, with these 190
            Attendance Positions (PAs) being the lowest figure obtained by the
            two types of calculation (185 and 195).

3.1.1. - The number of Attendance Positions (PAs) calculated each day may not
exceed the number agreed by the Parties and based on the Sizing proposed by the

                                     A-127


CONTRACTED PARTY, pursuant to Item 2.1.

3.1.2 - The CONTRACTED PARTY will be paid for the number of Attendance Positions
(PAs) higher than forecast for the day with the formal approval of the
CONTRACTING PARTY.

3.2 - Billing for the "Labor Force Operator" - unit price for the "Labor Force
Operator" / Customer Care Representative (RA) as shown in the Price List,
multiplied by the total number of Customer Care Representatives (RAs),
calculated in compliance with the following rules:

      -     The Sizing for the Customer Care Representatives (RAs) will include
            an increase of 3% (three per cent) to cover Absenteeism paid by the
            CONTRACTING PARTY.

      -     The calculation formula for the "Labor Force Operator" should be
            based on the Logged Agents Report taken from the Traffic Control
            System (CMS), for each interval of 30 (thirty) minutes, taking the
            "Labor Force Operator" working full-time on the Operation with
            payment for each Attendance Position (PA), in addition to the "Labor
            Force Operator" shared with a second Operation (Multiskill).

     For two cells remunerated by Attendance Position (PA), there is no
     alteration to the manner of calculating the remuneration of the Customer
     Care Representatives (RAs), as the first Operator skill defines the cell to
     which he belongs.

      -     For an operation not sharing the skills of the Customer Care
            Representatives (RAs) (single skill), the calculation of the
            remuneration will be carried out in compliance with the following
            formula :

 (Total Logged Agents for each 30 min. X 0.5 hour - Total Overtime + Total
                                    de Hours

                             Worked and Not Logged)

                   (6 hours) X (1 + Contracted Absenteeism 3%)

3.2.1 - The number of Customer Care Representatives (RAs) calculated each day
may not be higher than agreed by the Parties on the basis of the Sizing proposed
by the CONTRACTED PARTY, pursuant to Item 2.1.

3.2.2 - The CONTRACTED PARTY will be paid for the number of Customer Care
Representatives (RAs) higher than forecast for the day only with the formal
approval of the CONTRACTING PARTY.

3.3 - Billing for the "Labor Force Supervisor" - unit price for the" Labor Force
Supervisor" as stipulated in the Price List, multiplied by the total number of
Supervisors and calculated in compliance with the following rules:

3.3.1 - Each team with no more than 25 Customer Care Representatives (RAs) will
be allocated and billed for a Supervisor.

3.4 - Billing Overtime for Customer Services - will be charged in full, and the
portion of the unit cost of the "Labor Force Operator" and Labor Force
Supervisor", pursuant to the

                                     A-128


Price List, in the situations listed below:

3.4.1 - ANATEL Metering Days - compliance with the regulations (SMP4).

4 -- HALTS IN THE OPERATIONS

4.1.1 -- For occurrences that may result in a halt in the operations, the causes
thereof should be identified in order to allocate responsibility and liability
as required in order to remedy such situations.

4.1.2 -- When the causes are related to the infrastructure and / or technology
that is the responsibility of the CONTRACTING PARTY, it should remunerate the
CONTRACTED PARTY based on the duration of the halt and the consequences thereof.
The CONTRACTED PARTY should be remunerated as though such an event had not
occurred, consequently expunging the effects thereof from the services invoiced
and fines agreed for poor operating performance shown through the contractual
Performance Indicators: Service Level, % of the Group within the Average
Attendance Time (TMA) Range and % Trouble Tickets (TTS) Opened x Calls Answered.

- -     Eligibility to receive the Bonus will be defined for the period between
   the months in which the field surveys are carried out, paid out as from the
   month checked.

   e.g..: if the survey is carried out in April 2005 and the Ranking reaches
   1.6, the monthly bonus will be R$ 200,000, with payment beginning in May 2005
   and ending in August 2005 (bonus for January - April 2005).

Should the second survey be carried out in August 2005, the eligibility of these
findings will be considered for the months between the surveys, namely
May - August 2005, with payments schedule for September-December 2005.

- -     Should a survey be carried out prior to the complete settlement of a bonus
   awarded for an earlier survey, the outstanding amount will be settled in full
   in the month during which the second survey is analyzed.

For the example given above, assume another survey is carried out in July 2005.
In this case, an amount of R$ 400,000 will be paid out in July 2005 for March -
April 2005.

- -     Any outstanding amounts of bonuses still payable by December 2005 should
   be settled in full.

- -     The CONTRACTED PARTY should transfer at least 50% (fifty per cent) of the
award to the Operations, in the manner it deems appropriate and duly proven to
