Amortization Schedule.

In the event that on the
day immediately following the Final Disbursement Date, the aggregate amount of
Disbursements made hereunder is less than the aggregate maximum principal amount of
Disbursements permitted under Article II, the amount equal to the undisbursed amount
shall be deducted pro ratafrom each of the installments of the Loan shown in the

the resulting increases to such installments being deducted from the last installment),
unless such undisbursed balance is less than the last installment, in which case the
whole amount thereof shall be deducted from the last installment alone.

Promptly after the Final
Disbursement Date and at the time of any amendment to the Amortization Schedule, the
Agent shall draw up an amended Amortization Schedule which shall replace the original
Amortization Schedule and be binding upon the Borrower, and the Agent shall notify the
Borrower thereof and furnish the Borrower with a copy thereof without delay, whereupon
the Borrower shall be irrevocably and unconditionally obliged to repay the Loan in
accordance therewith.  Such Amortization Schedule shall be conclusive in the absence of
manifest error.

(2) (Prepayment
Circumstance) The Borrower shall not at any time prepay any outstanding amount of the
Loan other than in accordance with Section (3) of this Article IV or Section (2) of

necessary to make such prepayment and upon giving not less than thirty (30) calendar days prior
irrevocable notice in writing to the Agent and the Guarantor, prepay all or any part of
the Loan on a Payment Date in advance of the final Repayment Date together with all
accrued interest on the respective amounts so prepaid up to and including the day

Article VInterest,
Commitment Charge and Overdue Payment

(1) (Interest) Each
Disbursement shall bear interest on the outstanding principal amount therefor, for each
day during each Interest Period, at a rate per annum equal to the Floating Rate
applicable to such Interest Period plus the Applicable Spread. The Borrower shall pay
such interest to the LENDERS in arrears on each Payment Date for the period commencing on
and including the date of the first Disbursement (in the case of the initial payment of
interest on such Disbursement) or the immediately preceding Payment Date (in the case of
each subsequent payment of interest) up to but excluding such Payment Date.

(2) (Commitment Charge)

(a)   The Borrower shall
pay to the LENDERS ratably in proportion to their Credit Exposures, a commitment
      charge at the rate of two-fifths of one percent (0.4%) per annum on the daily
undrawn and uncancelled       portion of the Facility.

(b)   Such commitment
charge shall accrue from and including the date hereof to the Final Disbursement
      Date. Such commitment charge shall be payable in arrears on each Payment Date
during the period       commencing on the date hereof (in the case of the initial payment
of such commitment charge) or the       immediately preceding Payment Date (in the case
of each subsequent payment of such commitment charge)       up to and including such
first-mentioned Payment Date or the Final Disbursement Date, as the case may       be.

(3) (Default Interest)

(a) In case the
Borrower fails to pay any principal or interest payable under this Agreement on the due
date therefor (hereinafter referred to as the Overdue Amount), the Borrower shall
pay to the LENDERS interest (Overdue Interest), to the fullest extent permitted
by applicable law, on such Overdue Amount for each day during the period from and
including the due date therefor to the date of actual receipt by the LENDERS
thereof (hereinafter referred to as the Overdue Period), at a rate per annum
equal to the sum of the Overdue Floating Rate (as defined below), the Applicable Spread
and one percent (1.00%). Such Overdue Interest shall accrue as well after as
before judgment and in accordance with Section (4) of this Article V. Interest at
the rate stipulated in Section (1) of this Article V shall not accrue on any
Overdue Amount during the Overdue Period.

The Overdue Floating Rate means,
in this Section (3) of this Article V, the rate per annum (on the basis of a
360-day year), shown on the Telerate Page 3750 (or such other page as may replace such
page on such screen for the purpose of displaying London interbank offered rates of
major banks for deposits in Yen) as the British Bankers Association Interest
Settlement Rate in Yen (LIBOR) for a period of six (6) months, or if no rate
appears on such page on any Overdue Interest Calculation Date (as defined below) in
the Overdue Period, the average (rounded upwards, if necessary, to the nearest
1/16th of 1%) of the respective rates per annum at which deposits in Yen are
offered to the Reference Banks in the London interbank market, in each case, as of
approximately 11:00 a.m. (London time) on such Overdue Interest Calculation Date.
In the event that such rate is not available at such time for any reason, then the
applicable the Overdue Floating Rate shall be determined by the Agent in a
commercially reasonable manner after consulting with the LENDERS and the Borrower.

The Overdue Interest
Calculation Date means two (2) LIBOR Business Days prior to:

(i)    the Repayment Date
or Payment Date, as applicable, on which the Overdue Amount became due and
             payable;

(ii)   (a) the Repayment
Date or Payment Date, as applicable, next succeeding the previous Repayment
             Date or Payment Date, as the case may be, in the event that the Overdue
Amount continues to be              unpaid on such subsequent Repayment Date or Payment
Date, as the case may be, or (b) each              March 24 and September 24 which
succeeds the final Repayment Date hereunder, in the event that              the Overdue
Amount is or continues to be unpaid on such date; and

(iii)  in the event that
the Overdue Amount became due and payable on any day other than a Repayment
             Date or a Payment Date, then the Repayment Date or Payment Date immediately
preceding the date              the Overdue Amount became due and payable, or the March
24 or September 24 immediately              preceding the date the Overdue Amount became
due and payable, in the event that the Overdue              Amount is or continues to be
unpaid after the final Repayment Date.

(b)   Payment of interest
by the Borrower in accordance with paragraph (a) of this Section (3) shall not
      prejudice the right of the LENDERS to exercise any other of its rights or claims
hereunder, at law or       otherwise to remedy any such failure to pay any amount on the
due date for payment hereunder, and in       particular its rights under Article IX
hereof.

(4) (Basis of
Calculation) Interest, commitment charge and any other fees on the Loan shall accrue on
a day-to-day basis and be computed on the basis of a year of three hundred and sixty-
(360) days and the actual number of days elapsed (fractional sums of less than one Yen (¥ 1.-)
being disregarded).

date for payment thereof to the account of the Collection Agent as is notified to the

Currency, as the case may be, except to the extent to which such amount, tender or
recovery so expressed, paid, made or converted shall result (when converted to the
currency in which the obligation is denominated in accordance with the relevant LENDER's
usual foreign exchange practices) in the effective receipt by the LENDERS of Yen or the
Relevant Currency, as the case may be, and the Borrower shall, as a primary obligation
enforceable as an alternative or additional cause of action for the purpose of recovery
in Yen or the Relevant Currency, as the case may be, indemnify the LENDERS against the
amount (if any) by which such effective receipt shall fall short of the full amount of
Yen or the Relevant Currency, as the case may be, payable under this Agreement, and such
indemnity shall not be affected by any judgment obtained for any other sum due under this
Agreement.

(5) (Insufficient
Payment) If the amount of any payment made by the Borrower on the due date therefor
under this Agreement is less than the total amount due and payable in respect of such
payment, the Agent (on behalf of the LENDERS) shall apply the payment so made in or
towards the satisfaction of any or all of the amounts which are due or overdue for
payment on such day in the following order (or in such other order as the Agent may agree
with the Borrower from time to time to be appropriate in the circumstances): (a)
costs and expenses (and amounts under indemnities in respect of costs and expenses)
due under this Agreement (to the extent the Agent has been notified that such

otherwise provided for in this Section (5) of Article VI, providedthat: (g)
if any payment is insufficient to pay an amount referred to in any of paragraphs (a)
to (f) (inclusive) above in full, the Agent shall apply the payment received pro
rata in proportion to the amounts owing under the Loan in reduction of the amount
referred to in the relevant paragraph above and, with respect to amounts applied
to the Loan, in the chronological order in which such sums fell due; and(h) if the Guarantor
makes any payment with respect to the Guaranteed Unpaid Amount (as defined in the
Guarantee Agreement) pursuant to the terms of the Guarantee Agreement, the
parties hereto agree for the express benefit of the Guarantor that, from the
date the Guarantor makes such payment until the date the Borrower reimburses
the Guarantor in full therefor and discharges in full any other outstanding
payment obligations or other obligations that it may owe the Guarantor under the
Indemnity Agreement, all payments made by the Borrower under this Agreement
shall be applied in accordance with the provisions of Section 3.2
(Application of Payments) of the General Agency Agreement.

LENDERS a sum equal to the total amount of the Guarantee Fee (as defined in the Guarantee
Agreement) which would have accrued had no such acceleration occurred, together with the
cost to the LENDERS of funding such amount.

Article XIIYield
Protection

(1) (Inability to
Determine Interest Rates) If on or before the first day of any Interest Period, (a) the
Agent is advised by the Reference Banks that deposits in Yen (in the applicable amounts)
are not being offered to the Reference Banks in the London interbank market for such
Interest Period or (b) a LENDER (an Affected LENDER) advises the Agent that the
Floating Rate as determined by the Agent will not adequately and fairly reflect the cost
to such Affected LENDER of funding its ratable share of Disbursements during such
Interest Period, the Agent shall promptly give notice thereof to the Borrower and the
Borrowers right to request the making of, and the Affected LENDERs obligations to make,
Disbursements shall be suspended until such time as the circumstances giving rise to such
suspension no longer exist. Upon the giving of such notice, the Agent and the Guarantor
shall negotiate with the Borrower with a view to agreeing upon a reasonable alternative
basis for calculating the interest payable on and/or for making, maintaining and/or
funding of such Disbursements. Any alternative basis so agreed within 30 days of the
notification by the Agent of the event in question shall take effect in accordance with
the terms so agreed. If an alternative basis is not so agreed within such 30-day period,
such Disbursements shall, during such Interest Period, bear interest at the rate per
annum equal to the sum of the Applicable Spread and the direct cost of such Affected
LENDER (expressed as a rate per annum) of funding or maintaining outstanding its ratable
share of such Disbursements during such Interest Period (as determined in good faith by
the Agent), which determination shall be conclusive and binding on the Borrower for all
purposes in the absence of manifest error); provided that, upon the request of the
Borrower, the Agent shall describe in writing to the Borrower, in reasonable detail, the
calculation of such direct cost.

(2) (Illegality) If,
on or after the date hereof, the adoption of any applicable law, rule or regulation, or
any change in any applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance by any
LENDER with any request or directive (whether or not having the force of law) of such
authority, central bank or comparable agency, shall make it unlawful or impossible for
any LENDER to make, maintain or fund its Credit Exposure and such LENDER shall so notify
the Agent, the Agent shall forthwith give notice thereof to the other LENDERS and the
Borrower, whereupon until such LENDER notifies the Borrower and the Agent that the
circumstances giving rise to such suspension no longer exist, the obligation of such
LENDER to fund its Credit Exposure shall be suspended. At the request of such LENDER,
the Borrower shall, on the next Payment Date for interest on the Loan (or upon such
earlier date as such LENDER may advise the Borrower is the latest date on which such
LENDER may make, maintain or fund its Credit Exposure or the affected portion thereof
under applicable law) repay such LENDERs ratable share of the Loan or the affected
portion thereof (including all interest accrued thereon and fees and expenses payable in
connection therewith) of such LENDER if such LENDER shall notify the Borrower that such
LENDER may not lawfully continue to fund and maintain its Credit Exposure or the affected
portion thereof.

(3) (Increased Cost and
Reduced Return) (a) If on or after the date hereof, the adoption of any applicable law,
rule or regulation, or any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any LENDER with any request or directive (whether having the
force of law) of any such authority, central bank or comparable agency, shall impose,
modify or deem applicable any reserve, special deposit, insurance assessment or similar
requirement against assets of, deposits with or for the account of, or credit extended
by, any LENDER or shall impose on any LENDER or on the London interbank market any other
condition affecting funding of its Credit Exposure and the result of any of the foregoing
is to increase the cost to such LENDER of funding or maintaining the funding of its
Credit Exposure, or to reduce the amount of any sum received or receivable by such LENDER
under this Agreement or under its Note with respect thereto, by an amount deemed by such
LENDER to be material, then, within 15 days after demand by such LENDER (with a copy to
the Agent), the Borrower shall, at its option, (i) pay, upon delivery of documentary
evidence of such increase, to such LENDER such additional amount or amounts as will
compensate such LENDER for such increased cost or reduction; or (ii) repay such LENDERs
ratable share of the Loan or the affected portion thereof (including all interest accrued
thereon and fees and expenses payable in connection therewith).

(b)  If any LENDER shall
have determined that, after the date hereof, the adoption of any applicable law, rule or
regulation regarding capital adequacy, or any change in any such law, rule or regulation,
or any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy (whether
or not having the force of law) of any such authority, central bank or comparable agency,
has the effect of reducing the rate of return on capital of such LENDER (or its parent)
as a consequence of such LENDERs obligations hereunder to a level below that which such
LENDER (or its parent) could have achieved but for such adoption, change, request or
directive (taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such LENDER to be material, then from time to time, within 15 days after
demand by such LENDER (with a copy to the Agent), the Borrower shall, at its option, (i)
pay, upon delivery of documentary evidence of such increase, such LENDER such additional
amount or amounts as will compensate such LENDER (or its parent) for such reduction; or
(ii) repay such LENDERs ratable share of the Loan or the affected portion thereof
(including all interest accrued thereon and fees and expenses payable in connection
therewith).

(c)  Each LENDER will
promptly notify the Borrower and the Agent of any event of which it has knowledge,
occurring after the date hereof, which will entitle such LENDER to compensation pursuant
to this Section (3).  A certificate of any LENDER claiming compensation under this
Section (3) and setting forth the additional amount or amounts to be paid to it hereunder
shall be conclusive in the absence of manifest error.  In determining such amount, such
LENDER may use any reasonable averaging and attribution methods.

Article XIIIThe Agent

Under and subject to the
terms of the General Agency Agreement, each LENDER shall appoint the Agent to act as its
agent in relation to the implementation of the transactions contemplated by this
Agreement and the General Agency Agreement.  In addition, the Collection Agent shall be
appointed to act as a collection agent for and on behalf of the LENDERS and the Guarantor
pursuant to the General Agency Agreement.

Consultation) The parties hereto undertake to use their best efforts to resolve any
dispute arising out of or in connection with this Agreement through consultation in good

(3) (Submission to
Jurisdiction)

(a)   The Borrower hereby
irrevocably agrees that each of the Tokyo District Court, the courts of the State
      of New York and the courts of the United States of America in New York shall have

arise out of or in connection with this       Agreement and agrees not to claim that any
such court is not a convenient or appropriate forum.

(c)   The submission to
the jurisdiction of the courts referred to in paragraph (a) of this Section (3)
      shall not (and shall not be construed so as to) limit the right of the LENDERS to
take proceedings       against the Borrower in any other court of competent jurisdiction
nor shall the taking of proceedings       in any one or more jurisdictions preclude the
taking of proceedings in any other jurisdiction,       whether concurrently or not.

(d)   The Borrower hereby
consents generally in respect of any legal action or proceedings arising out of       or
in connection with this Agreement to the giving of any relief or the issue of any process

such action or proceedings, except in the case of enforcement       proceedings in the
Borrowers Country relating to the assets of the Borrower which, under applicable

The Borrower agrees that without limiting any other means available to the LENDERS, the
process by which any suit, action or proceedings is begun, or any other document
regarding the initiation of suit, action or proceedings, may be validly served on the

If for any reason the
Tokyo Process Agent or the New York Process Agent shall cease, or shall not be capable so
to act, the Borrower shall promptly and irrevocably designate and appoint another agent
acceptable to the LENDERS. Failure by the Borrower to designate and appoint another agent
acceptable to the LENDERS within fifteen (15) days shall entitle the LENDERS to appoint
any Person acceptable to them as agent of the Borrower by notice to the Borrower.

(5) (Waiver of
Immunity) To the extent that the Borrower may now or hereafter in any jurisdiction claim
for itself or its assets immunity from process, suit, execution, attachment (whether in
aid of execution, before judgment or otherwise) or other legal process and to the extent
that in any such jurisdiction there may be attributed to the Borrower or its assets such
immunity (whether or not claimed), the Borrower hereby irrevocably consents generally to

sale of any state property) and the Borrower further irrevocably agrees not to claim and
hereby irrevocably waives such immunity to the fullest extent permitted by the laws of
such jurisdiction and, in particular, in relation to any proceedings that may be taken in

consent of the Majority LENDERS; provided that no such amendment or waiver shall, unless
signed by each LENDER, (i) reduce the principal of or rate of interest on the Loan or any

(v) increase the Commitment of such LENDER or subject such LENDER to any additional
obligation, or (vi) change the Commitment of such LENDER.

(2) (Successors and

(b) Any LENDER (a Granting
LENDER) may at any time grant to one or more banks or other institutions (each a Participant)
participating interests in its Commitment or its ratable share of the Loan. The Granting
LENDER shall remain responsible for the performance of its obligations hereunder, and the
Borrower and the Agent shall continue to deal solely and directly with such LENDER in
connection with such LENDERs rights and obligations under this Agreement. Any agreement
or instrument pursuant to which the Granting LENDER sells such a participation shall
provide that such LENDER shall retain the sole right to enforce the Transaction Documents
and to approve any amendment, modification or waiver of any provision of the Transaction
Documents; provided that such agreement or instrument may provide that such LENDER will

proportionate part of all, of its rights and obligations under this Agreement and its
Note, and such Assignee shall assume such rights and obligations, pursuant to an
assignment and assumption agreement substantially in the form of Annex G hereto signed by
such Assignee and such transferor LENDER, with (and subject to) the subscribed consent of
the Borrower (which shall not be unreasonably withheld) and the Agent, provided that if
an Assignee is an affiliate of such transferor LENDER or was a LENDER immediately before
such assignment, no such consent shall be required. When such instrument has been signed
and delivered by the parties thereto and such Assignee has paid to such transferor LENDER
the purchase price agreed between them, such Assignee shall be a LENDER party to this
Agreement and shall have all the rights and obligations of a LENDER with a commitment as
set forth in such instrument of assumption, and the transferor LENDER shall be released
from its obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment pursuant
to this subsection, the transferor LENDER, the Agent and the Borrower shall make
appropriate arrangements so that, if required, a new Note is issued to the Assignee. In
connection with any such assignment, the transferor LENDER shall pay to the Agent an
administrative fee for processing such assignment in the amount of ¥ 300,000.

(d)  No assignee,
Participant or other transferee of any LENDERs right shall be entitled to receive any
greater payment under Article XI or Section (2) or (3) of Article XII than such LENDER
would have been entitled to receive with respect to the rights transferred, unless such
transfer is made with the Borrowers prior written consent.

hereto were upon the same instrument. This Agreement constitutes the entire agreement
and understanding among the parties hereto and supersedes any and all prior agreements
and understandings, oral or written, relating to the subject matter hereof. This
Agreement shall become effective when the Agent has received from each of the parties
hereto a counterpart hereto signed by such party or facsimile or other written
confirmation satisfactory to the Agent confirming that such party has signed a
counterpart hereof.

(4) (WAIVER OF JURY
TRIAL) EACH OF THE BORROWER, THE AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVES ANY AND
ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(5) (No Release) No
claim or dispute arising out of and/or in connection with any other contract or
agreement, shall have any effect upon the Borrowers obligations under this Agreement nor
in any way be deemed to release the Borrower therefrom, such obligations being absolute
and unconditional.

(6) (No Waiver,
Remedies Cumulative) No failure or delay on the part of the Agent or any other LENDER in
exercising any right hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any right preclude any other or further exercise thereof, or the
exercise of any other right. No waiver by the Agent or any other LENDER hereunder shall
be effective unless it is in writing. The rights and remedies provided herein are
cumulative and not exclusive of any other right or remedy provided by law.

(7) (Partial
Illegality) If at any time any provision hereof becomes illegal, invalid or
unenforceable in any respect under the laws of any jurisdiction, neither the legality,
validity nor enforceability of any other provision hereof nor the legality, validity or
enforceability of such provision under the laws of any other jurisdiction shall in any
way be affected or impaired thereby.

documentary evidence.

|    | Re: Loan to BRT under JBIC Guarantee      

Dear Sirs:

We have acted as
independent legal counsel to Brasil Telecom S.A. (the Borrower)and have advised the
Borrower in connection with a loan agreement dated as of March 24, 2004 between the
Borrower, the financial institutions listed on the signature page thereto as lenders and
Sumitomo Mitsui Banking Corporation, as agent and collection agent (the Agreement).

All terms and expressions
defined in the Agreement shall bear the same meaning in this opinion.

This opinion is given to
you pursuant to Section (1)(i) of Article X of the Agreement and at the request of the
Borrower.

After examining all
relevant documents, including an executed copy of the Transaction Documents, and making
all enquiries which we consider necessary or desirable for the opinion hereafter
expressed and having regard to the laws and regulations of the Federative Republic of
Brazil (the Borrowers Country) which we consider relevant, we are of the opinion that:

(1) The Borrower is a
corporation duly incorporated and validly existing under the laws of the Borrowers
Country as a sociedade anô nimaand has full power and authority to carry on its business
(including the Project) as now being conducted and is a legal entity with separate legal
personality capable of being sued in its own name.

(2)   The Borrower has
full power and authority to enter into each Transaction Document, to borrow under the
Agreement and to perform and observe the terms and conditions of each Transaction
Document.  The Borrower has taken and completed all action or procedures necessary to
approve the transactions contemplated in each Transaction Document and to authorize the
Borrower to execute, deliver and perform each such Transaction Document and to perform
its obligations thereunder.

(3) All authorizations,
licenses, approvals or consents of, or registrations, recordations or filings with, the
Borrowers Country, or of any agency, department, or commission thereof or therein which
is necessary for (a) the execution, delivery or performance of each Transaction Document
or any agreement or instrument required thereunder, (b) the legality, validity,
enforceability and admissibility in evidence thereof, (c) the borrowings under the
Agreement or (d) the payment by the Borrower of all sums which it may be liable to pay
under the Transaction Documents in Yen or the Relevant Currency, as the case may be, have
been duly effected, completed and/or obtained and are in full force and effect, (A)
including, but not limited to, the electronic registration of the Loan with Banco Central
do Brasil by means of the SISBACEN system called Registration of Financial Transaction (Registro
de Operação Financeira  ROF) (ROF)and all related authorizations, registrations (or
amendments thereof) and communications from, with or in respect of ROF and/or any
department of Banco Central do Brasil which may be required prior to each Disbursement
hereunder by the applicable regulations of the Borrowers Country, which has been made
and is in full force and effect, or shall be made or be in full force and effect prior to
such Disbursement, and (B) except for (i) the registration of each Disbursement and the
related schedule of payments with respect thereto with Banco Central do Brasil, which the
Borrower shall promptly effect after the entrance of such Disbursement into the Borrowers
Country in accordance with Article VIII of the Agreement, (ii) the notarization of the
signature of the parties to each Transaction Document by a notary public licensed under
the laws of the place of signing; (iii) the consularization of each Transaction Document
in the appropriate Brazilian consulate in the event that such Transaction Document is not
executed in the Borrowers Country; and (iv) the registration of each Transaction
Document, together with a sworn translation of each Transaction Document into the
Portuguese language, with the appropriate Registry of Deeds and Documents, which
registration can be made at any time prior to the enforcement thereof in the Borrowers
Country.

(4)   Each Transaction
Document has been duly executed and delivered by the duly authorized representative(s) of
the Borrower.  Each Transaction Document constitutes the legal, valid and binding
obligation of the Borrower enforceable against the Borrower in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency, reorganization or
other similar laws affecting the enforcement of creditors rights generally and by
general principles of equity, regardless of whether such enforceability is considered in
a proceeding in equity or at law.

(5)   The execution,
delivery and performance of each Transaction Document and all instruments and agreements
required thereunder do not contravene, violate or constitute a default under (a) any
provision of the articles of incorporation, by-laws or other constituent documents or
capital stock of the Borrower; (b) any material provision of any material agreement or
other material instrument to which the Borrower is a party or by which the Borrower or
any of its assets is or may be bound; (c) any treaty, law or regulation applicable to the
Borrower; or (d) any judgment, injunction, order or decree binding upon the Borrower or
any of its assets, nor would the same result in the creation or imposition of any
Encumbrance on any asset of the Borrower.

(6)   No event has
occurred and is continuing or would result from the making of any Disbursement hereunder
which constitutes or would constitute a Default or a material default under any material
agreement, mortgage, indenture, note or other material instrument to which the Borrower
is a party or by which the Borrower or any of its assets is or may be bound.

(7)   There are no legal,
administrative or other actions, claims or other proceedings current, pending or, to the
Borrowers knowledge, threatened against the Borrower or the Project which if decided
adversely would materially and adversely affect the financial condition, business or
operations of the Borrower and its Consolidated Subsidiaries or the Project or would
materially and adversely affect the Borrowers ability to perform its obligations under
any Transaction Document or which question the legality, validity or binding effect of
any provision of any Transaction Document or the authority of the Borrower to execute any
of the Transaction Documents.

(8)   Under the laws of
the Borrowers Country, there is no Tax payable (whether by withholding or otherwise) on
or by virtue of the execution and delivery of any Transaction Document or any document or
instrument to be executed and delivered thereunder, the performance, enforcement or
admissibility in evidence thereof, or on any payment required to be made thereunder,
except for a withholding tax with respect to payments of interest under the Agreement.

(9) The obligations and
liabilities of the Borrower under each Transaction Document are unconditional and general
obligations of the Borrower and rank at least pari passuwith all other present or future
unsecured and unsubordinated Indebtedness (both actual and contingent) of the Borrower.

(10)  In any proceedings
in the Borrowers Country to enforce any Transaction Document, the choice of New York law
or Japanese law (as the case may be) as the governing law thereof will be recognized and
such law will be applied, the irrevocable submissions of the Borrower to the
non-exclusive jurisdiction of the Tokyo District Court, the courts of the State of New
York and the courts of the United States of America in New York and the appointment by
the Borrower of the Tokyo Process Agent and the New York Process Agent are legal, valid,
binding and enforceable and any judgment obtained in Japan or New York will be recognized
and enforceable against the Borrower and its assets in the Borrowers Country after
having been duly ratified by the Federal Supreme Court of the Borrowers Country; such
ratification by the Supreme Court of the Borrowers Country will occur if the court
decision in such jurisdiction (i) complies with all formalities required for the
enforcement thereof under the laws of such jurisdiction; (ii) was issued by a competent
court in such jurisdiction after valid service of process upon the parties to the action
(such service to have been made under the authority of a court or the clerk of a court),
or after sufficient evidence of the parties absence has been given in accordance with
the applicable law of such jurisdiction; (iii) is not subject to appeal; (iv) is not
against public policy, national sovereignty or good morals of the Borrowers Country and
does not contain any other provision of a similar nature; (v) is duly authenticated by
the competent consulate of the Borrowers Country in such jurisdiction and is accompanied
by a translation thereof into Portuguese made by a sworn translator; and (vi) in the case
of proceedings in the Borrowers Country to enforce a payment obligation under the
Agreement, it is also required that any judgment obtained in Japan or New York be for the
payment of a determined amount.

Each Transaction Document
is in proper legal form under the laws of the Borrowers Country and is capable of
enforcement in the courts of the Borrowers Country.

There is no requirement
to file, register or otherwise record any Transaction Document or any instrument or
agreement required thereunder in any public office or elsewhere in the Borrowers Country
to ensure the validity, legality, effectiveness, enforceability or admissibility in
evidence hereof or thereof, except for the approvals, registrations and other actions
referred to in Section (3) of Article VII of the Agreement.

Each Note shall
constitute a valid título executivo, enforceable against the Borrower in accordance with
applicable law.

(11)  The Borrower is
subject to civil and commercial law with respect to its obligations under each
Transaction Document.  The execution and delivery of each Transaction Document
constitute, and the Borrowers performance of and compliance with its obligations under
each Transaction Document will constitute, private and commercial acts rather than public
or governmental acts.

(12)  The waiver of
immunity by the Borrower in Section (5) of Article XIV of the Agreement is legal, valid,
binding and enforceable and neither the Borrower nor any of its assets has any right of
immunity from suit, execution, attachment prior to judgment, attachment in aid of
execution or any other legal process with respect to its obligations under any
Transaction Document in any jurisdiction, including, without limitation, the Borrowers
Country.

(13)  The Project
description and details contained in Annex B are true and accurate in all respects.

(14) It is not necessary
under the laws of the Borrower's Country that any LENDER or the Agent be licensed or
qualified to do business in the Borrower's Country solely as a result of its execution,
delivery or performance of the Transaction Documents, except that each LENDER will be
required, pursuant to Normative Instruction No. 200, of September 13, 2002, issued by the
Federal Revenue Service (Secretaria da Receita Federal)of the Ministry of Finance (Ministé rio
da Fazenda), as amended, to obtain a federal taxpayer's identification number (número de
inscrição no cadastro de pessoas jurídicas)in the Borrowers Country.

Yours faithfully,
