          AMENDMENT TO CONTACT CENTER SERVICE, IDENTIFIED AS CN 0988/04

By this private Agreement, entered into by ORBITALL SERVICOS E PROCESSAMENTO DE
INFORMACOES COMERCIAIS S.A., current name of ORBITALL SERVICOS E PROCESSAMENTO
DE INFORMACOES COMERCIAIS LTDA., a corporation with headquarters in the city of
Sao Caetano do Sul, Sao Paulo state, at Rua Manoel Coelho, 600, 1st floor,
enrolled with the Ministry of Finance (CNPJ/MF) under number 00.006.878/001-34,
hereinafter referred to as ORBITAL, and TNL CONTAX S.A., a corporation located
at Rua do Passeio, 48 to 56 - part of, Center, in the Capital of the State of
Rio de Janeiro, enrolled with the Ministry of Finance (CNPJ/MF) under number
02.757.614/001-48, hereinafter referred to as PARTNER, represented by their
undersigned legal representatives pursuant to their By-laws, mutually agree, as
from the date of execution of this Agreement, to change the Clauses and
Conditions of the Contact Center Service Agreement, identified as CN 0988/04,
entered into on April 01, 2004, hereinafter referred to as AGREEMENT, as
follows:

1. ACQUISITION AND GUARANTEE OF THE VOLUME OF TIME SPOKEN - The parties agree to
change item 4.1.4 of clause four of the AGREEMENT, as follows:

ORBITALL, or formally appointed third parties, shall prepare and submit to
PARTNER the monthly planning of the volume of time spoken (number of calls times
the average time of service) 75 ( seventy five) days before the first day of the
month of the service rendering.

The planning communicated within 75 days may be reviewed in up to 45 (forty
five) days before the first day of the month of the service rendering and the
revised volume may be up to 10% greater or 10% inferior to the volume originally
communicated.


                                        1

<PAGE>

When the planned volume is not informed with 75 days precedence, the volume
presented in the previous month will be considered valid. When the volume is not
revised within 45 days, the volume presented within 75 days will be considered
valid.

In those cases in which the monthly time spoken of a given center is inferior to
90% (ninety percent) of the monthly volume informed within 45 days, PARTNER
shall, for the purpose of invoicing, consider 90% (ninety percent) of the
monthly volume informed, for the purpose of minimum invoicing guarantee for said
center.

If the volume fulfilled by a given center is inferior to 90% of the planned
volume during 3 (three) consecutive months, ORBITALL shall pay PARTNER a penalty
calculated as follows: anticipated invoicing for the month for the related
center multiplied by (90% - moving average of the last 3 months of the volume
fulfilled divided by the planned volume). This penalty is limited to 3% of the
value of the month's invoicing of the respective center.

The payment of the minimum guarantee of the volume of time spoken by ORBITALL is
contingent to the fulfillment by PARTNER of the agreed upon TSFs, other than
situations in which the loss of TSFs has been caused by unavailability of the
infrastructure made available by ORBITALL or as expressly decided by ORBITALL.

If the volume fulfilled in the month is 10% greater than the volume planned by
ORBITALL, PARTNER shall be exempt from paying the fine for non-fulfillment of
the agreed-upon TSF levels. Notwithstanding the aforementioned exemption from
paying the fine, PARTNER shall make every effort to fulfill the applicable TSFs
Level agreements.

2. SERVICE LEVEL - The parties agree to change sub-line "iv" of item 12.1 of
Clause Twelve of the agreement hereby amended, which will enter in force with
the following wording:

"The financial penalties due to non fulfillment of the applicable service levels
shall not exceed 15% (fifteen percent) of the value of the monthly invoice
corresponding to the month in which the event occurred."

3. ESTABLISHMENT OF DAILY SERVICE LEVEL AGREEMENTS - The parties hereby
establish that for each average monthly TSF, a corresponding minimum daily TSF
shall be followed, as shown in the chart below:

<TABLE>
<CAPTION>
Monthly TSF   Minimum Daily TSF
-----------   -----------------
<S>           <C>
  85%-20"          60%-20"
  90%-30"          70%-30"
  70%-30"          60%-30"
  90%-20"          70%-20"
  65%-20"          55%-20"
</TABLE>

The commitment to the daily TSF Service Level shall be observed so long as the
fulfilled time spoken does not exceed 5% (five percent) of the planned daily
time spoken for the 3 (three) days of greatest activity (DMMs) and does not
exceed 10% (ten percent) of the daily planned volume for the remaining days of
the month.

The parties establish that if the conditions above are not fulfilled, PARTNER
shall pay ORBITALL, as a penalty, the value equivalent to the quantity of time
spoken fulfilled that differs from the agreed-upon TSF, plus 25%.

The fulfillment of the daily TSFs does not release PARTNER from fulfilling the
monthly TSFs, neither exempts PARTNER of the related fines.

December of the previous year + 75% (seventy five percent) times the Labor Cost
Variation (**)."

(*)  General Market Price Index - IGPM, published by Getulio Vargas Foundation -
     FGV. In the event of suspension, extinction and/or prohibition of using the
     IGPM-FGV as the price adjustment index, the parties elect, as substitute,
     the index that officially substitutes it or, in the event of such index not
     being determined, the one that best reflects the maintenance of the
     economic-financial balance of this contractual adjustment, as agreed by the
     Parties.

(**) Labor Cost Variation: refers to the percentage of the category's collective
     labor agreement or bilateral agreement between the PARTNER and the trade
     union, agreed in January of the year of adjustment. The consideration of
     other amounts negotiated between the PARTNER and its employees for the
     purpose of adjusting the prices paid by ORBITALL shall be negotiated
     separately.

The price review to be made in January 2007 shall consider the percentage
equivalent to the period from April to December 2006.

invoicing shall be calculated based on the average monthly invoicing accrued in
the 3 (three) months prior to the termination date. The minimum value of this
fine is equal to 1 (one) month's invoicing.

representatives of both parties, the corresponding amount to be reimbursed being
limited to 30% (thirty percent) of the value of the monthly invoice
