The remuneration of the Debentures will be determined by the Issuer following
deliberation at an MSB, yet to be held, in line with the interest rate
ascertained during the bookbuilding procedure, and will bear the characteristics
described in the Preliminary Supplement. Following the definition of the
remuneration for each of the Series of Debentures, items 4.2.1.1, 4.2.1.4 and
4.2.2.1 will be altered accordingly, by means of an amendment to the present
Indenture.

4.2.1 REMUNERATION OF THE DEBENTURES OF THE 1ST SERIES

4.2.1.1 The Nominal Value of the Debentures of the 1st Series will, in
accordance with item 4.2 above and after deducting amortization, incur
remunerative interest equivalent to a maximum of 105% (one hundred and five
percent) of the average daily rate for the DI (Interbank Overnight Deposits)
Non-Group index ("DI Rate"), calculated and released daily by the CETIP,
expressed as an annual percentage, using a 252 (two hundred and fifty two)
working day base, and calculated exponentially and cumulatively, on a pro rata
basis according to the number of working days that have elapsed ("Remuneration
of the 1st Series").

4.2.1.2 The Capitalization Period of the 1st Series is defined as the period
beginning at the Issue Date, inclusively, in the case of the first
Capitalization Period of the 1st Series, or at the date prescribed for the
payment of interest for the preceding period, inclusively, in the case of the
other Capitalization Periods of the 1st Series, and ends on the day preceding
the date prescribed

                                       7

<PAGE>

for the payment of interest for that period, inclusively. Each Capitalization
Period of the 1st Series will succeed the previous one, without interruption.
The corresponding interest for each Capitalization Period of the 1st Series
becomes due and will be paid on a half yearly basis, with the first payment
coming due on September 1, 2006 and the last on March 1, 2011.

4.2.1.3 Remuneration of the 1st Series will be calculated exponentially and
cumulatively on a pro rata basis, according to the number of working days that
have elapsed, based on the Nominal Unit Value of the Debentures, after deducting
amortization, as from the Issue Date, or from the maturity date of the previous
Capitalization Period of the 1st Series, as the case may be, up to the effective
date of payment, according to the formula below.

4.2.1.4 Interest will be calculated according to the following formula:

          I = NV x (DIFactor - 1):

where:

I         Remuneration of the 1st Series due at the end of each Capitalization
          Period of the 1st Series, as defined in item 4.2.1.2 above,
          calculated to 6 (six) decimal places, with no rounding up.

NV        Nominal Unit Value of the Debentures of the 1st Series at the
          beginning of the Capitalization Period of the 1st Series, given to 6
          (six) decimal places, with no rounding up.

DI FACTOR the product of the DI Rate from the starting date of Capitalization
          Period of the 1st Series, inclusively, to the end of the
          Capitalization Period of the 1st Series, calculated to 8 (eight)
          decimal places, rounded off, which is obtained as follows:

                                    n     (              P )
                   DIFactor = (Pie Symbol)(1 + DIR(k) x ---):
                                   k=1    (             100)

          where:

          N      total number of DI Rates, "n" being a whole number.

          P      at most, 105 (one hundred and five)

          DIR(k) DI Rate, released daily, calculated to 8 (eight) decimal
                 places, rounded off, as follows:

                                                1
                                               ---
                                               252
                                    (DI(k)    )
                           DIR(k) = (----- + 1)    - 1
                                    ( 100     )

          where:

          K     1, 2, ..., n

          DI(k) DI Rate announced by the CETIP, expressed as an annual
                percentage.

                                       8

<PAGE>

4.2.1.5 The DI Rate should be utilized employing exactly the same number of
decimal places as the figure released by the CETIP.

                                             (               P  )
4.2.1.6 The factor yielded by the expression (1 + (TDI(k) x ---)) is considered
                                             (              100 )
using 16 (sixteen) decimal places, without rounding up.

                                                     (               P  )
4.2.1.7 The product is obtained of the daily factors (1 + (TDI(k) x ---)), and
                                                     (              100 )
as each daily factor is accumulated, the result is cut off to 16 (sixteen)
decimal places, before the next daily factor is applied, and so on until the
last factor has been applied.

4.2.1.8 In the event of the temporary unavailability of the DI Rate, for a
period of less than 10 (ten) consecutive days, then for the payment of any
monetary obligation provided for under this clause, the latest available daily
DI Rate prior to the calculation date will be used instead, applying the
percentage defined in item 4.2.1.1, and calculated on a pro rata basis, with no
financial compensation being due to either party, whether the Issuer or the
Debenture holders of the 1st Series, in relation to any differences that arise
when the respective DI Rates are eventually released. In the event of the
temporary unavailability of the DI Rate for a period of more than 10 (ten)
consecutive days from the date of its expected announcement or, with immediate
effect, in the event that the DI Rate is abolished or that it is not possible to
apply the DI Rate due to legal imposition or judicial determination, then the
provisions of item 4.2.1.9 below will come into effect.

4.2.1.9 In the event that the DI Rate is not determined and/or not released
during a period of more than 10 (ten) consecutive days from the date of its
expected announcement or, with immediate effect, in the event that the DI Rate
is abolished or that it is not possible to apply the DI Rate due to legal
imposition or judicial determination, then the rate that is adopted in its place
by the market agents for similar transactions will automatically be applied in
its stead. If it is not possible to replace the DI Rate on the aforementioned
basis, the Fiduciary Agent must call a general meeting of the Debenture holders,
to be held within a maximum of 20 (twenty) days from the date of the event that
gave reason for calling this meeting, in order to decide, with the consent of
the Issuer, the new reference interest rate to be utilized in the remuneration
of the Debentures, to which will be applied the same Remuneration defined in the
bookbuilding procedure, so as to not only preserve the real value of the
Debentures, but to remunerate them at the same levels as before. Should
debenture holders representing at least 75% (seventy-five percent) of the
outstanding Debentures not approve the Issuer's proposal of a new parameter, the
outstanding Debentures should all be redeemed, and consequently cancelled, at
their Nominal Value, plus all Remuneration due up to the redemption date,
calculated on a pro rata basis, from the Issue Date or from the date of the last
Remuneration payment, up until the effective date of payment, as well as any
other amounts that may be due from the Issuer under the terms of this Indenture,
within a period of 10 (ten) days from the date that the aforementioned general
meeting of the debenture holders was closed. No premium of any kind will be
added to the redemption referred to in this item. Up until the moment that a new
parameter, or a redemption date, is defined, depending on the case, it is hereby
agreed that the last daily DI Rate officially released will be utilized,
calculated on a pro rata basis from the date of the event up until the date that
the debenture

                                       9

holders and the Issuer agree on a new parameter, or up to the date of the
redemption payment, respectively.

4.2.2 REMUNERATION OF THE DEBENTURES OF THE 2ND SERIES

4.2.2.1 The Nominal Unit Value of the Debentures of the 2nd Series will, in
accordance with item 4.2 above, incur interest equivalent to the sum of the
average daily rates for the DI (Interbank Overnight Deposits) Non-Group index
("DI Rates"), calculated and released by the CETIP, plus a spread of, at most,
0.90% (point nine, zero percent) per annum, using a 252 (two hundred and fifty
two) working day base, as from the Issue Date, to be paid at the end of each 2nd
Series Capitalization Period, according to the formula below ("Remuneration of
the 2nd Series" and, together with the Remuneration of the 1st Series,
"Remuneration").

4.2.2.2 The Capitalization Period of the 2nd Series is defined as the period
beginning at the Issue Date, inclusively, in the case of the first
Capitalization Period of the 2nd Series, or at the date prescribed for the
payment of interest for the preceding period, inclusively, in the case of the
other Capitalization Periods of the 2nd Series, and ends on the day preceding
the date prescribed for the payment of interest for that period, inclusively.
Each Capitalization Period of the 2nd Series will succeed the previous one,
without interruption. The corresponding interest for each Capitalization Period
of the 2nd Series becomes due and will be paid on a half yearly basis, with the
first payment coming due on September 1, 2006 and the last on March 1, 2013.

4.2.2.3 The average daily rates are accumulated exponentially on a pro rata
basis, up until the effective date of payment of the interest, so as to include
the whole Capitalization Period of the 2nd Series.

4.2.2.4 Interest will be calculated according to the following formula:

                I = NVi x (InterestFactor - 1):

where:

I               unit value of the floating interest rate, plus a spread, if
                applicable, accumulated over the period, calculated to 6 (six)
                decimal places, with no rounding up, that is due at the end of
                each Capitalization Period for Debentures of the 2nd Series.

NVI             Nominal Value at issue or balance of the Nominal Value of the
                Debentures of the 2nd Series, provided/calculated to 6 (six)
                decimal places, with no rounding up.

INTEREST FACTOR interest factor, comprising the fluctuation parameter plus a
                spread, if applicable, calculated to 9 (nine) decimal places,
                rounded up or down, as follows:

                    InterestFactor = DIFactor x SpreadFactor

                                       10

          Period, up to, but not including the calculation date, calculated to 8
          (eight) decimal points, rounded up or down, as follows:

                          n(DI)   (            )

4.2.2.5 The DI Rate should be utilized employing exactly the same number of
decimal places as the figure released by the entity responsible for its
calculation.

4.2.2.6 The factor yielded by the expression [(1 + TDI(k))] is considered using
16 (sixteen) decimal places, with no rounding up.

4.2.2.7 The product is obtained of the daily factors [(1 + TDI(k))], and as each
daily factor is accumulated, the result is cut off to 16 (sixteen) decimal
places, before the next daily factor is applied, and so on until the last factor
has been applied.

4.2.2.8 In the event of the temporary unavailability of the DI Rate, for a
period of less than 10 (ten) consecutive days, then for the payment of any
monetary obligation provided for under this clause, the latest available daily
DI Rate prior to the calculation date will be used instead, plus a spread,
applying the percentage defined in item 4.2.2.1, and calculated on a pro rata
basis, with no financial compensation being due to either party, whether the
Issuer or the Debenture holders of the 2nd Series, in relation to any
differences that arise when the respective DI Rates are eventually released. In
the event of the temporary unavailability of the DI Rate for a period of more
than 10 (ten) consecutive days from the date of its expected announcement or,
with immediate effect, in the event that the DI Rate is abolished or that it is
not possible to apply the DI Rate due to legal imposition or judicial
determination, then the provisions of item 4.2.2.9 below will come into effect.

4.2.2.9 In the event that the DI Rate is not determined and/or not released
during a period of more than 10 (ten) consecutive days from the date of its
expected announcement or, with immediate effect, in the event that the DI Rate
is abolished or that it is not possible to apply the DI Rate due to legal
imposition or judicial determination, then the rate that is adopted in its place
by the market agents for similar transactions will automatically be applied in
its stead. If it is not possible to replace the DI Rate on the aforementioned
basis, the Fiduciary Agent must call a general meeting of the Debenture holders,
to be held within a maximum of 20 (twenty) days from the date of the event that
gave reason for calling this meeting, in order to decide, with the consent of
the Issuer, the new reference interest rate to be utilized in the remuneration
of the Debentures, to which will be applied the same Remuneration defined in the
bookbuilding procedure, so as to not only preserve the real value of the
Debentures, but to remunerate them at the same levels as before. Should
debenture holders representing at least 75% (seventy-five percent) of the
outstanding Debentures not approve the Issuer's proposal for a new parameter,
the outstanding Debentures should all be redeemed, and consequently cancelled,
at their Nominal Value, plus all Remuneration due up to the redemption date,
calculated on a pro rata basis, from the Issue Date or from the date of the last
Remuneration payment, up until the effective date of payment, as well as any
other amounts that may be due from the Issuer under the terms of this Indenture,
within a period of 10 (ten) days from the date that the aforementioned general
meeting of the debenture holders was closed. No premium of any kind will be
added to the redemption referred to in this item. Up until the moment that a new
parameter, or a redemption date, is defined, depending on the case, it is hereby
agreed that the last daily DI Rate officially released will be utilized,
calculated on a pro rata basis from the date of the event up until the date that
the debenture holders and the Issuer agree on a new parameter, or up to the date
of the redemption payment, respectively.

4.5  AMORTIZATION

The Debentures will not be subject to amortization.

4.6  PAYMENT LOCATION

Payments for the Debentures will be made on the respective maturity dates,
using, as the case may be: (i) the procedures adopted by the CBLC, for

4.7  EXTENSION OF PERIODS

The maturity of the payments of any obligations by any of the parties, including
by the Debenture holders in regard to the payment of the subscription price,
will be extended to the next working day, should the maturity fall on a bank or
commercial holiday in the city where the Issuer is based, without any alteration
in the value to be paid, with the exception of those cases where the payment is
to be made by the CETIP or by the CBLC, in which case the same extension will
only be conceded when the maturity date falls on a national holiday or a
weekend. For the purpose of this Indenture, working days are defined as all
those days that are not considered, under the terms of this item, as days
subject to the extension of the maturity date ( "Working Days"). In the case of
item 4.2, working days are those recognized as such by the CETIP and/or the
BovespaFix.

In the case of late payment of any amount due to the Debenture holders, the
amount in arrears will be subject, in addition to Remuneration, a late payment
fine of 2% (two percent) of the amount due and interest calculated from the due

incurred in collection.

4.9  LAPSING OF THE RIGHT TO ADDITIONS

Without impairment to the provisions of item 4.8 above, the non-appearance of
the Debenture holder to receive payment of any monetary obligations on the part
of the Issuer, on the dates determined in this Indenture or in a communication
published by the Issuer, will not entitle the absentee to receive any moratory
income and/or charges in relation to the delay in receiving such payment,
notwithstanding that all rights acquired up to the respective maturity are
safeguarded.

4.10 IMMUNITY OF THE DEBENTURE HOLDERS

Should any Debenture holder be entitled to any kind of tax immunity or

to the Representative Bank, within a minimum of 10 (ten) Working Days prior to
the date prescribed for receipt of the amounts relating to Debentures.

to dispose of the Debentures to which they hold title.

4.12 DISCRETIONARY EARLY REDEMPTION

These Debentures will not be subject to early redemption by the Issuer, except
under the circumstances described in items 4.2.1.9 and 4.2.2.9.

4.13 REPRICING

the interests of the Debenture holders, should obligatorily be communicated in
the form of notices, published in the financial newspaper Valor Economico and
