today issuing U.S.$200,000,000 aggregate principal amount of notes (the “Notes”);  

    WHEREAS, in order to
maximize the interests of the holders of the Notes (the “Noteholders”), the Overseas

the Notes, enter into a Contract of Insurance for Fixed Income Securities Against
Inconvertibility (the “Insurance Policy”) with, and for the benefit of, the Insurance

trustee hereunder, and the Insurance Trustee hereby accepts the Insurance Trust created
hereby and declares that it will hold all estate, right, title and interest of the
Insurance Trust in and to all Insurance Trust Property in trust for the use and benefit
of the Noteholders from time to time in their capacity as Trust Beneficiaries, all in
accordance with the terms and provisions of this Agreement.  

    (b)     By its signature

other Transaction Document to which the Insurance Trustee, on behalf of the Insurance
Trust, is a party, (ii) accept the Assignment, (iii) perform its duties thereunder and
(iv) otherwise act in accordance with the terms hereof. 

    Section 2.02.
Acceptance by Trustee. (a) The Insurance Trustee, upon the execution and delivery
of this Agreement, (i) acknowledges its acceptance of all right, title, ownership and
interest in and to the Insurance Trust Property acquired pursuant to the terms hereof and
Section 5.2(d) of the Indenture, (ii) declares that the Insurance Trustee holds and will

promptly following the establishment of the Insurance Trust, copies of the Indenture and
all other Transaction Documents. 

    Section 2.03.

(i) holding the Insurance Policy and the other Insurance Trust Property, (ii) prosecuting

Article III

INTEREST IN THE
INSURANCE TRUST 

    Section 3.01.
Evidence of Interests in Insurance Trust. The beneficial interests in the Insurance
Trust shall be (i) owned, legally and beneficially, by the Noteholders in their capacity
as Trust Beneficiaries in the form of an undivided interest in the Insurance Trust
Property and (ii) deemed to be a right that is part and parcel of the Notes, represented
by the Notes and shall not be detachable, severable or in any way subject to transfer
separate and apart form an interest in the Notes, and all Noteholders in their capacity
as Trust Beneficiaries by their acceptance of the Notes agree to the foregoing
restrictions on separate transfer of any interest in the Insurance Trust or Insurance
Trust Property and that, consistent with the Indenture, any attempt by a Noteholder (or
an interest therein) to do so shall be null and void. Each Noteholder in its capacity as
Trust Beneficiary shall have an interest in such portion of the Insurance Trust Property,
including the Covered Interest Period Amounts, as the principal amount of the Notes owned
by that Noteholder bears to the total principal amount of the Notes.  

    Section 3.02.
Withdrawal from Insurance Trust. Each Trust Beneficiary shall at all times have the
right to cease to be a beneficiary of the Insurance Trust (a “Departing Beneficiary”) by
providing not less than thirty days prior written notice to both the Insurance Trustee
and the Indenture Trustee, and at the effectiveness of any such request, the Insurance
Trustee shall reassign to such Departing Beneficiary, without recourse, a pro rata
interest in the Covered Interest Period Amounts on the understanding and agreement by the
Departing Beneficiary (in its capacity as Noteholder or otherwise) that by ceasing to be
a beneficiary of the Insurance Trust such Departing Beneficiary shall, under current
applicable law and the current arrangements under which the Insurance Policy is issued,
surrender its direct or indirect interest in the Insurance Policy.  

    Section 3.03. Rights
of Enforcement. Subject to the rights of the Insurer under the Insurance Policy, each
Trust Beneficiary, in its capacity as a Noteholder, shall, individually and without the
need to act in concert with any other Trust Beneficiary or the Insurance Trustee, be
entitled to exercise the rights and remedies assigned to the Insurance Trust in respect
of the Covered Interest Period Amounts, including all rights under Section 7.9 of the
Indenture applicable thereto.  

Article IV

THE INSURANCE POLICY 

    Section 4.01. Payment
of Premium. The Issuer hereby confirms that the total premium due in respect of the
Insurance Policy has been paid by the Issuer to the Indenture Trustee on behalf of the
Insurance Trust for further credit to the Insurer on or prior to the Closing Date.  

    Section 4.02. Payment
Instructions for Covered Interest Period Amounts. The Noteholders in their capacity as
Trust Beneficiaries, by acceptance of their Notes, hereby acknowledge and agree that:  

    (a)      Unless otherwise
instructed hereunder, all payments to the Noteholders (in their capacity as Trust
Beneficiaries hereunder) shall be made to the Indenture Trustee, or to the extent that
the Principal Paying Agent shall remain appointed under the Indenture, to the Principal
Paying Agent, by depositing all such amounts in the Payment Account to be paid over to
the Noteholders in their capacity as Trust Beneficiaries. 

    (b)      The Insurer
shall have the rights set forth in the Insurance Policy and described in Section 4.03(c)
hereof with respect to the Covered Interest Period Amounts. 

    (c)      If,
notwithstanding the Assignment, no claim is ever made under the Insurance Policy, then,
unless otherwise instructed pursuant hereto, the Issuer shall pay to the Indenture
Trustee, or to the extent that the Principal Paying Agent shall remain appointed under
the Indenture, to the Principal Paying Agent, all such amounts as would otherwise be
payable to the Insurance Trust in respect of the Covered Interest Periods by depositing
all such amounts in the Payment Account to be paid over to the Trust Beneficiaries in
their capacity as such consistent with their rights to receive principal, interest and
other amounts due from time to time under the Notes and the Indenture. 

    (d)      If
notwithstanding any other provision of this Agreement the Insurance Trustee shall receive
any payment in respect of the Covered Period Interest Amounts, unless otherwise
instructed pursuant hereto, all such amounts as are received by the Insurance Trustee
shall be promptly paid over to the Indenture Trustee, or to the extent that the Principal
Paying Agent shall remain appointed under the Indenture, to the Principal Paying Agent on
behalf of the Trust Beneficiaries by depositing all such amounts in the Payment Account
and neither the Insurance Trust nor the Insurer nor any other Person shall be entitled to
retain or receive any such Covered Interest Period Amount (or any portion or proceeds
thereof). 

    (e)      Any payments
received by the Noteholders pursuant to Section 3.2(c) and 5.1(a)(i)(C) of the Indenture
in respect of the amounts set forth in clause (iv) of the definition of Required Amount
in the Indenture shall be deemed to be a payment to the Noteholders in their capacity as
Trust Beneficiaries in respect of the portion of the Covered Interest Period Amounts not
covered by the Insurance Policy. 

    Section 4.03. Claims
on the Insurance Policy. (a) The Insurance Trustee agrees to file with the Insurer such
claim applications as are required under the Insurance Policy upon the occurrence of any
Currency Inconvertibility Event. In connection with the filing of a claim with the
Insurer of amounts payable under the Insurance Policy, the Insurance Trustee shall direct
the Insurer to make any payment under the Insurance Policy to the Indenture Trustee, or
to the extent that the Principal Paying Agent shall remain appointed under the Indenture,
to the Principal Paying Agent, by depositing all such amounts to the Payment Account to
be paid over to the Trust Beneficiaries in their capacity as such.  

    (b)      The Insurance
Trustee shall give all notices, make all filings and take all actions required of it
pursuant to the terms of the Insurance Policy, including, without limitation, the filing
of a claim with the procedures and subject to the time limitations set forth in Article
IV of the Insurance Policy.  In connection with its satisfaction of its obligations
hereunder and under the Insurance Policy, the Issuer hereby agrees to provide all such
information and take all such actions as are required hereunder or thereunder, including,
without limitation, ensuring the continued enforceability of the Insurance Policy in
connection with the submission of any claim thereunder and the satisfaction of any
requirement provided therein. 

    (c)      If a claim is
made under the Insurance Policy: 

    (i)
In accordance with Section 3.01.1(a) of the Insurance Policy, the Insurance Trustee shall
(or          shall require the Issuer to, and the Issuer shall), at the election of the
Insurer, prior to          payment of a claim by the Insurer, either: 

    (1)   deliver
or cause to be delivered to the Insurer (A) inconvertible reais, in an amount
equal to the Insured Portion of the Covered Interest Period Amounts relating to such
claim at the rate of exchange specified in the Insurance Policy, or (B) non-transferable
U.S. dollars, in an amount equal to the Insured Portion of the Covered Interest Period
Amounts relating to such claim (in either case in the form of (x) funds immediately
available to the Insurer in Brazil or, (y) at the Insurer’s option, in cash); or

    (2)
assign to the Insurer, or, at the Insurer’s option, grant to the Insurer a participation
in, the                   Insurance Trustee’s right to receive the Insured Portion of the
Covered Interest Period                   Amounts relating to such claim; or 

    (3)
(A) assign to the Insurer, or, at the Insurer’s option, grant to the Insurer a
participation in, the Insured Portion of the Covered Interest Period Amounts relating to
such claim in the applicable deposit account in which such reais or
non-transferable U.S. dollars are, held by, or for, or at the direction of, the Issuer,
and (B) assign to the Insurer, or, at the Insurer’s option, grant to the Insurer a
participation in, all rights of such Person with respect to the Insured Portion of the
Covered Interest Period Amounts relating to such claim thereof and all claims with
respect thereto arising out of the Currency Inconvertibility Event, including, without
limitation, claims against the Brazilian government.

    (ii)   To
the extent provided in the Insurance Policy, the Insurer shall be subrogated to the
rights of          the Noteholders (and, as a result of the Assignment of the Covered
Interest Period Amounts under          Section 5.2(d) of the Indenture, of the Insurance
Trust) with respect to any payment of interest          on the Notes with funds provided
by the Insurer under the Insurance Policy (except to the extent          that the Insurer
has requested and received reais or non-transferable U.S. dollars as described in
         Section 4.03(c)(i)(1)). 

    (iii)
The Insurance Trustee is not to release the Issuer from its obligation to make scheduled
payments of interest on the Notes with respect to the Insured Portion of the Covered
Interest Period Amounts (or any part thereof) for which the Insurance Trustee has
received reais or non-transferable U.S. dollars until the Insurer has (as
described in Section 4.03(c)(i)(1)) agreed to accept delivery of such reais or
non-transferable U.S. dollars in discharge of the obligation of the Issuer to make
scheduled payments of interest on the Notes with respect to the Insured Portion of the
Covered Interest Period Amounts, the Insurer has received such amounts, and the Insurance
Trustee has received compensation under the Insurance Policy. Further, the Insurance
Trustee and, in accordance with the Indenture, the Indenture Trustee are not to release
the Issuer from its obligation to make scheduled payments of interest on the Notes with
respect to the Insured Portion of the Covered Interest Period Amounts (or any part
thereof) if the Insurer agrees (as described in Section 4.03(c)(i)(2) or (3)) to accept
an assignment of, or participation in, the rights of the Insurance Trustee or the Issuer,
as the case may be, in the applicable deposit account or to receive scheduled payments of
interest on the Notes with respect to the Insured Portion of the Covered Interest Period
Amounts (or any part thereof) in lieu of receiving reais or non-transferable U.S. dollars
in exchange for payment by the Insurer of compensation under the Insurance Policy unless
the Insurer notifies the Insurance Trustee and the Indenture Trustee in writing that it
has received payments from the Issuer under the Company Support Agreement representing
such previously compensated amounts and then only to the extent of such payments by the
Issuer to the Insurer. 

    (d)
     The Issuer shall at all times use its best efforts to assist the Insurance Trustee
in seeking compensation pursuant to the Insurance Policy. 

    Section 4.04.
Undertakings Required by the Insurance Policy. (a) Only the Insurance Trustee may
exercise its rights and obligations under the Insurance Policy. No individual Trust
Beneficiary shall be permitted to exercise any right under the Insurance Policy or
perform any obligations in lieu of the Insurance Trustee under the Insurance Policy. By
accepting the Notes, the Noteholders in their capacity as Trust Beneficiaries acknowledge
that the independent rights of salvage of the Insurer contained in the Insurance Policy
will not be subject to any pari passu sharing arrangements of the nature referred to in
Section 4.04 of the Insurance Policy.  

    (b)      By accepting the
Notes, the Noteholders in their capacity as Trust Beneficiaries acknowledge, as
contemplated by Section 4.10 of the Insurance Policy, that they will be bound by the
actions and omissions of the Insurance Trustee under the Insurance Policy, including,
without limitation, the grant of assignments or participations under Section 3.01.1 of
the Insurance Policy and described in Section 4.03(c)(i) or the submission of a Final
Application (as defined in the Insurance Policy) with respect to the Insurance Policy. 

    (c)      By accepting the
Notes, the Noteholders in their capacity as Trust Beneficiaries acknowledge, as
contemplated by Section 4.11 of the Insurance Policy, that no description, summary or
characterization of the terms of the Insurance Policy contained in the offering materials
with respect to the Notes shall (i) be treated as an amendment, interpretation or
construction of the Insurance Policy which would be binding on the Insurer, or (ii)
introduced in any proceeding for any such purpose.  With respect to the interpretation of
any provision of the Insurance Policy, in the event of any inconsistency between the
terms of the description, summary or characterization of the terms of the Insurance
Policy in the offering materials with respect to the Notes, and the terms of the
Insurance Policy, the terms of the Insurance Policy shall govern, it being agreed that
the Insurer takes no responsibility for any description, summary or other
characterization of the terms of the Insurance Policy contained in the offering materials
with respect to the Notes, regardless of whether the Insurer has knowledge thereof. 

    (d)      By accepting the
Notes, the Noteholders in their capacity as Trust Beneficiaries acknowledge, as
contemplated by Section 5.02(b) of the Insurance Policy, that to the extent that the
Insurer has already paid in full any compensation which should have been reduced pursuant
to Section 5.02(b) of the Insurance Policy (with respect to the Holder Representations
set forth in Section 5.2(f)(i)(1) of the Indenture), OPIC may directly recover the amount
of the reduction from any Noteholder (in its capacity as Trust Beneficiary) whose
compensation should have been reduced pursuant to Section 5.02(b) of the Insurance Policy. 

    Section 4.05.
Termination of Insurance Policy. (a) At any time on or after the third or any
subsequent anniversary of the Closing Date and so long as, to the knowledge of the
Insurance Trustee (after consultation with the Indenture Trustee), no Default or Event of
Default has occurred and is continuing, the Insurance Trustee, at the written direction
of the Issuer, may cancel the Insurance Policy in accordance with the terms of the
Insurance Policy, upon receipt of 90-calendar-days prior written confirmation from Moody’s
and Fitch that its then current rating of the Notes is at least “Baa3” and “BBB-”,
respectively, and that such ratings will not be lowered or withdrawn as a result of such
cancellation. Any refund of the premium originally paid by the Issuer on behalf of the
Insurance Trustee at Closing shall not be part of the Insurance Trust Property and shall
be paid to the Issuer.  

    (b)     Except as
provided in Section 4.05(a), the Insurance Trustee shall not have authority to terminate
the Insurance Policy unless it is instructed to do so by the all Noteholders. 

    Section 4.06.
Covenants of Issuer. The Issuer hereby covenants and agrees with the Insurance Trust
that in connection with any application by the Insurance Trustee for compensation
pursuant to the Insurance Policy in respect of Currency Inconvertibility Event, the
Issuer shall (i) make all reasonable efforts to convert reais into U.S. dollars or to
transfer such U.S. dollars through all customary legal channels for transactions of the
type contemplated in the Transaction Documents until compensation is paid by the Insurer,
(ii) assist the Insurance Trustee with the preparation of such application for
compensation and (iii) perform, at the request of the Insurance Trustee, the obligations
set forth in Section 3.01.1(a)(i) or (iii) of the Insurance Policy.  

Article V

    Section 5.01. Certain
Rights and Duties of Insurance Trustee. (a) The Insurance Trustee undertakes to perform
only such duties as are specifically set forth in this Agreement, the Insurance Policy
and each other Transaction Document to which the Insurance Trustee is a party, and no
implied covenants or obligations shall be read into this Agreement against the Insurance
Trustee. The Insurance Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of his or her
own affairs.  

    (b)      Except as
otherwise provided in Section 315 of the Trust Indenture Act: 

    (i)
the Insurance Trustee may conclusively rely and shall be fully protected in acting, or
refraining          from acting, upon any resolution, certificate, statement, instrument,

or document reasonably believed by it in          good faith to be genuine and to have
been signed or presented by the proper party or parties;

    (ix)
the Insurance Trustee shall not be bound to make any investigation into the facts or
matters          stated in any resolution, certificate, statement, instrument, opinion,
report, notice, request,          consent, entitlement order, approval or other paper or
document; 

    (x)
the Insurance Trustee shall not be deemed to have notice of any Default or Event of
Default under          the Indenture unless a Responsible Officer of the Insurance
Trustee has actual knowledge thereof          or unless written notice of any event which
is in fact such a default is received by the Insurance          Trustee at the Corporate
Trust Office of the Insurance Trustee, and such notice references the          Notes and
the Indenture; 

    (xi)
the rights, privileges, protections, immunities and benefits given to the Insurance
Trustee,          including, without limitation, its right to be indemnified, are

Certificate, including any person specified as so authorized in          any such
certificate previously delivered and not superseded.

    (c)      None of the
provisions contained in this Agreement shall require the Insurance Trustee to expend or
risk its own funds or otherwise incur personal financial liability in the performance of
any of its duties or in the exercise of any of its rights or powers, if there shall be a
reasonable ground for believing that the repayment of such funds or indemnity
satisfactory to it against such liability is not reasonably assured to it. 

    (d)      The Insurance
Trustee may reasonably request information, including an Officer’s Certificate, from time
to time, as necessary or appropriate in order to ascertain compliance with the
requirements of this Agreement and may consult with counsel and the written advice or

    Section 5.04.

to the Insurance Trustee from time to time, and the Insurance Trustee shall be entitled to, reasonable
compensation for all services rendered by it hereunder (which shall be agreed to from

trust), and, except as herein otherwise expressly provided, the Issuer will pay or
reimburse the Insurance Trustee upon its respective request for all duly documented
reasonable expenses and disbursements incurred or made by the Insurance Trustee in
accordance with any of the provisions of this Agreement (including the reasonable
compensation and the reasonable expenses, advances and disbursements of its counsel and
of all persons not regularly in its employ, in each case duly documented) except any such
expense or disbursement as may arise from its gross negligence or bad faith.  The Issuer
also covenants and agrees to indemnify the Insurance Trustee for, and to defend and hold
harmless the Insurance Trustee and its officers, directors, employees, representatives
and agents from and against, any loss, liability, claim, damage or expense, including,
without limitation, the fees and expenses of its legal counsel, incurred without gross
negligence or bad faith on the part of the Insurance Trustee or any of their employees,
officers or agents, arising out of or in connection with the acceptance or administration
of the trust or trusts hereunder, the performance of its duties and-or the exercise of
its rights, including liability which the Insurance Trustee may incur as a result of
failure to withhold, pay or report Taxes and including the costs and expenses of
defending itself against any claim or liability in the premises and including, without
limitation, any loss, liability, claim, damage or expense relating to or arising out of
any Environmental Law.  In no event shall the Insurance Trustee be liable for special,
indirect or consequential loss or damages whatsoever (including, but not limited to, lost
profits), even if the Insurance Trustee has been advised of the likelihood of such damage
and regardless of the form of action taken.

    (b)     The obligations
of the Issuer under this Section 5.04 shall survive payment in full of the Notes and any
claim and payment under the Insurance Policy, the resignation or removal of the Insurance
Trustee and the termination of the Insurance Trust and this Agreement.

    (c)     When the
Insurance Trustee incurs expenses or renders services in connection with the performance
of its obligations hereunder after an Event of Default under the Indenture occurs, the
expenses and compensation for such services are intended to constitute expenses of
administration under applicable bankruptcy, insolvency or other similar United States
federal or state law to the extent provided in Section 503(b)(5) of the Federal
Bankruptcy Code.

    Section 5.05. Right
of Insurance Trustee to Rely on Officer’s Certificates and Opinions of Counsel. Before
the Insurance Trustee acts or refrains from acting with respect to any matter
contemplated by this Agreement, it may require an Officer’s Certificate of the Issuer or
an Opinion of Counsel, which shall conform to the provisions of Section 14.1 of the
Indenture. The Insurance Trustee shall not be liable for any action it takes or omits to
take in good faith in reliance on such certificate or opinion as set forth in Section
5.01(b)(v). 

    Section 5.06. Persons

least “A2” by Moody’s and (ii) meet the requirements of Section 5.01.2(a) of the
Insurance Policy. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of a supervising or examining authority referred
to in Section 310(a) of the Trust Indenture Act, then, for the purposes of this Section
5.06, the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so
published. In case at any time the Insurance Trustee shall cease to be eligible in
accordance with this Section 5.06, the Insurance Trustee shall resign immediately in the
manner and with the effect specified in Section 5.07. 

    Section 5.07.
Resignation and Removal of Insurance Trustee; Appointment of Successor. (a) The
Insurance Trustee, or any Insurance Trustee or Insurance Trustees hereafter appointed,

such resignation to the Noteholders (in their capacity as Trust Beneficiaries) in the
manner provided in Section 14.4 of the Indenture. 

    (b)      In case at any
time any of the following shall occur with respect to any
Notes:

    (i)      the Insurance
Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture
         Act, after written request by the Issuer or by any Noteholder (in its capacity
as Trust Beneficiary) who          has been a bona fide Noteholder for at least six
months,

    (ii)     the Insurance
Trustee shall cease to be eligible under Section 5.06 and shall fail to resign after
         written request therefor by the Issuer or by any Noteholder (in its capacity as
Trust Beneficiary), or

    (iii)    the Insurance
Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or
a          receiver of the Insurance Trustee or of its property shall be appointed, or
any public officer shall          take charge or control of the Insurance Trustee or of
its property or affairs for the purpose of          rehabilitation, conservation or
liquidation;

then, in any such case,
(A) the Issuer may remove the Insurance Trustee, and appoint a successor Insurance
Trustee by written instrument, in duplicate, executed by order of the Board of Directors
of the Issuer, or (B) subject to the requirements of Section 315(e) of the Trust
Indenture Act, any Noteholder (in its capacity as Trust Beneficiary) who has been a bona
fide Noteholder for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal of the
Insurance Trustee and the appointment of a successor Insurance Trustee.  Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, remove the
Insurance Trustee and appoint a successor Insurance Trustee.

    (c) The Majority
Noteholders (in their capacity as Trust Beneficiaries) may at any time remove the
Insurance Trustee and appoint a successor
Insurance Trustee by delivering to the
Insurance Trustee so removed, to the successor Insurance Trustee
so appointed and to the Issuer the evidence
provided for in Section 6.01 of the action
taken by the Noteholders (in their capacity as
Trust Beneficiaries), provided that unless a
Default or Event of Default under the
Indenture shall have occurred and be continuing,
the Issuer shall consent (such consent not to
be unreasonably withheld).  

    (d) If the Insurance
Trustee shall resign, be removed, or become incapable of acting or if a vacancy shall
occur in the office of Insurance Trustee with
respect to this Agreement for any cause, the
Issuer shall promptly appoint a successor
Insurance Trustee or Insurance Trustees by written
instrument, in duplicate, executed by order
of the Board of Directors of the Issuer, one
copy of which instrument shall be delivered to the
former Insurance Trustee and one copy to the
successor Insurance Trustee. If no successor
Insurance Trustee shall have been so
appointed and have accepted such appointment
pursuant to Section 5.08 within 30 calendar
days after the mailing of such notice of
resignation or removal, the former Insurance
Trustee may, at the Issuer’s expense,
petition any court of competent jurisdiction for
the appointment of a successor Insurance
Trustee, or any Noteholder (in its capacity
as Trust Beneficiary) who has been a bona fide
Noteholder for at least six months may,
subject to the requirements of Section 315(e)
of the Trust Indenture Act, on behalf of itself and
all others similarly situated, petition any
such court for the appointment of a successor
Insurance Trustee. Such court may thereupon
after such notice, if any, as it may deem proper and
prescribe, appoint a successor Insurance
Trustee.  

    (e) Any resignation
or removal of the Insurance Trustee and any appointment of a successor Insurance Trustee
pursuant to this Section shall become
effective only upon acceptance of appointment
by the successor Insurance Trustee as provided in
Section 5.08.

Acceptance of Appointment by Successor Insurance Trustee. (a) Any successor
Insurance Trustee appointed under Section 5.07 shall execute, acknowledge and deliver to
the Issuer and to its predecessor Insurance Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the predecessor
Insurance Trustee shall become effective and such successor Insurance Trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers,
trusts, duties and obligations of its predecessor Insurance Trustee hereunder, with like
effect as if originally named as Insurance Trustee herein; but, nevertheless, on the
written request of the Issuer or of the successor Insurance Trustee, the Insurance
Trustee ceasing to act shall, upon payment of any such amounts then due it pursuant to
the provisions of Section 5.04, execute and deliver an instrument transferring to such
successor Insurance Trustee all the rights, powers and trusts of the Insurance Trustee so
ceasing to act, and shall assign, transfer and deliver to such successor Insurance
Trustee all property and money as may be held by such Insurance Trustee ceasing to act.
Upon request of any such successor Insurance Trustee, the Issuer shall execute any and
all instruments in writing for more fully and certainly vesting in and confirming to such
successor Insurance Trustee all such rights and powers. Any Insurance Trustee ceasing to
act shall, nevertheless, retain a lien upon all property or funds held or collected by
such Insurance Trustee to secure any amounts then due it pursuant to Section 5.04. 

    (b)     No successor
Insurance Trustee shall accept appointment as provided in this Section 5.08 unless at the
time of such acceptance such successor Insurance Trustee shall be eligible under Section
5.06.

    (c)     Upon acceptance
of appointment by a successor Insurance Trustee, the Issuer shall give notice of the
succession of such Insurance Trustee hereunder to the Noteholders in their capacity as
Trust Beneficiaries in the manner provided in Section 14.4 of the Indenture.  If the
Issuer fails to give such notice within 10 calendar days after acceptance of appointment
by the successor Insurance Trustee, the successor Insurance Trustee shall cause such
notice to be given at the expense of the Issuer.

    Section 5.09. Merger,
Conversion or Consolidation of Insurance Trustee. Any Person into which the Insurance
Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the Insurance
Trustee shall be a party, or any Person succeeding to all or substantially all the
corporate trust business of the Insurance Trustee, shall be the successor of the
Insurance Trustee hereunder without the execution or filing of any paper or any further
act on the part of any of the parties hereto; provided that such successor Insurance
Trustee shall be qualified under the Trust Indenture Act and eligible under the
provisions of Section 5.06 hereof and Section 310(a) of the Trust Indenture Act.  

    Section 5.10. Reports
by Insurance Trustee. On or before July 15 in every year, so long as any Notes are
Outstanding, the Insurance Trustee shall transmit to the Noteholders (in their capacity
as Trust Beneficiaries) specified in Section 313(a) of the Trust Indenture Act a brief
report, dated as of the preceding May 15, to the extent required by Section 313 of the
Trust Indenture Act in accordance with the procedures set forth in said Section. A copy
of such report at the time of its mailing to Noteholders shall be filed with the SEC and
each stock exchange, if any, on which the Notes are listed. The Issuer shall promptly
notify the Insurance Trustee if the Notes become listed on any stock exchange or any
de-listing thereof, and the Insurance Trustee shall comply with Section 313(d) of the
Trust Indenture Act. 

    Section 5.11.
Insurance Trustee Risk. None of the provisions contained in this Agreement shall
require the Insurance Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if it shall have reasonable ground for believing that the repayment
of such funds or liability is not reasonably assured to it. Whether or not expressly
provided herein, every provision of this Agreement relating to the conduct or affecting
the liability of or affording protection to the Insurance Trustee shall be subject to
Section 5.01 and the requirements of the Trust Indenture Act. 

    Section 5.12.
Appointment of Co-Insurance Trustee. (a) It is the purpose of this Agreement that
there shall be no violation of any law of any jurisdiction denying or restricting the
right of banking corporations or associations to transact business as Insurance Trustee
in such jurisdiction. It is recognized that in case of litigation under this Agreement
or any Transaction Document, and in particular in case of the enforcement of any such
document on default, or in case the Insurance Trustee deems that by reason of any present
or future law of any jurisdiction it may not exercise any of the powers, rights or
remedies herein granted to the Insurance Trustee or hold title to the properties, in
trust, as herein granted, or take any other action which may be desirable or necessary in
connection therewith, it may be necessary that the Insurance Trustee appoint an
additional individual or institution as a separate or co-Insurance Trustee. The
following provisions of this Section 5.12 are adopted to these ends. 

    (b)     In the event that
the Insurance Trustee appoints an additional individual or institution as a separate or
co-Insurance Trustee, each and every remedy, power, right, claim, demand, cause of
action, immunity, estate, title, interest and lien expressed or intended by this
Agreement to be exercised by or vested in or conveyed to the Insurance Trustee with
respect thereto shall be exercisable by and vested in such separate or co-Insurance
Trustee but only to the extent necessary to enable such separate or co-Insurance Trustee
to exercise such powers, rights and remedies, and every covenant and obligation necessary
to the exercise thereof by such separate or co-Insurance Trustee shall run to and be
enforceable by either of them.

    (c)     Should any
instrument in writing be required by the separate Insurance Trustee or co-Insurance
Trustee so appointed by the Insurance Trustee for more fully and certainly vesting in and
confirming to him or it such properties, rights, powers, trusts, duties and obligations,
any and all such instruments in writing shall, on request, be executed, acknowledged and
delivered by the Issuer.  In case any separate Insurance Trustee or co-Insurance Trustee,
or a successor to either, shall die, become incapable of acting, resign or be removed,
all the estates, properties, rights, powers, trusts, duties and obligations of such
separate Insurance Trustee or co-Insurance Trustee, so far as permitted by law, shall
vest in and be exercised by the Insurance Trustee until the appointment of a new
Insurance Trustee or successor to such separate Insurance Trustee or co-Insurance Trustee.

    (d)     Every separate
Insurance Trustee and co-Insurance Trustee shall, to the extent permitted by law, be
appointed and act subject to the following provisions and conditions:

    (i)      all rights,
powers, duties and obligations conferred or imposed upon the Insurance Trustee shall be
         conferred or imposed upon and exercised or performed by the Insurance Trustee
and such separate          Insurance Trustee or co-Insurance Trustee jointly (it being
understood that such separate Insurance          Trustee or co-Insurance Trustee is not
authorized to act separately without the Insurance Trustee          joining in such act),
except to the extent that under any law of any jurisdiction in which any
         particular act or acts are to be performed the Insurance Trustee shall be
incompetent or unqualified to          perform such act or acts, in which event such
rights, powers, duties and obligations (including the          holding of title to any
property or any portion thereof in any such jurisdiction) shall be exercised and
         performed singly by such separate Insurance Trustee or co-Insurance Trustee, but
solely at the direction          of the Insurance Trustee;

    (ii)     no Insurance
Trustee hereunder shall be personally liable by reason of any act or omission of any
other          Insurance Trustee hereunder;

    (iii)    the Insurance
Trustee may at any time accept the resignation of or remove any separate Insurance
Trustee          or co-Insurance Trustee; and

    (iv)     each
co-Insurance Trustee appointed hereunder shall at all times be a bank that complies with
the          eligibility requirements set forth in Section 310(a) of the Trust Insurance
Act, have a combined capital          and surplus of U.S.$100,000,000, have its corporate
trust office in the Borough of Manhattan, The City          of New York and have a
long-term unsecured debt rating of at least “A2” by Moody’s.  If such bank
         publishes reports of condition at least annually, pursuant to law or to the
requirements of a          supervising or examining authority referred to in Section
301(a) of the Trust Insurance Act, then for          the purposes of this subsection, the
combined capital and surplus of such bank shall be deemed to be its          combined
capital and surplus as set forth in its most recent report of condition so published.

to enable the Insurance Trustee or such Noteholder (in its capacity as Trust Beneficiary)
to comply with the terms and conditions of the Insurance Policy. Without limiting the
foregoing, the Insurance Trustee will (i) take the steps specified in Article IV of the
Insurance Policy at the times and in the manner therein specified, (ii) promptly notify
the Insured and the Indenture Trustee upon obtaining Actual Knowledge (as defined in the
Insurance Policy) that it no longer meets the requirements set forth in Section 5.01.2(a)
of the Insurance Policy, in the manner therein specified, (iii) as promptly as reasonably
practicable, notify the Insurer of any circumstance of which the Insurance Trustee has
Actual Knowledge of any event that may render the Insurer liable under the Insurance
Policy, and of any Default or other defaults of which the Insurance Trustee has Actual
Knowledge as specified in Section 5.01.6 of the Insurance Policy, (iv) give prompt notice
to the Insurer in the event it obtains Actual Knowledge regarding a breach or potential
breach of the representations made by the Noteholders pursuant to Section 5.2(f) of the
Indenture in the manner set forth in Section 5.01.10. of the Insurance Policy and (v)
promptly note in the Insurance Trustee’s records the Insurer’s rights as subrogee and
assignee in respect of the Notes. 

    Section 5.15. Trustee’s
Liens. The Insurance Trustee, in its individual capacity, agrees that it will at its own
cost and expense promptly take any action as may be necessary to duly discharge and
satisfy in full any mortgage, pledge, lien, charge, encumbrance, security interest or
claim on or with respect to the Insurance Trust Property which is either (i) attributable
to the Insurance Trustee in its individual capacity and which is unrelated to the
transactions contemplated by this Agreement or the other Transaction Documents, or (ii)
which is attributable to the Insurance Trustee as trustee hereunder or in its individual
capacity and which arise out of acts or omissions which are prohibited by this Agreement.
The Insurance Trustee, in its individual capacity, further agrees and acknowledges that
the Insurance Trust Property shall not be considered assets of the Insurance Trustee and,
therefore, the Insurance Trust Property is not subject to any third-party claims against
the Insurance Trustee in its individual capacity. 

ARTICLE VI

CONCERNING THE NOTEHOLDERS  

    Section 6.01. Acts of
Noteholders. (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Agreement to be given or taken by Noteholders in their
capacity as Trust Beneficiaries or otherwise (collectively, an “Act” of such Noteholders,
which term shall also refer to the instruments or record evidencing or embodying the
same) may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Noteholders in person or by an agent duly appointed in
writing or, alternatively, may be embodied in and evidenced by the record of Noteholders
voting in favor thereof, either in person or by proxies duly appointed in writing, at any
meeting of Noteholders duly called and held in accordance with the provisions of Article
X of the Indenture, or a combination of such instruments and any such record. Except as
herein otherwise expressly provided, such action shall become effective when such
instrument or instruments or record, or both, are delivered to the Insurance Trustee.
Proof of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Agreement and (subject to Section 5.01)
conclusive in favor of the Insurance Trustee and the Issuer, if made in the manner
provided in this Section 6.01. The record of any meeting of Noteholders shall be proved
in the manner provided in the Indenture.  

    (b)     The fact and date
of the execution by any Person of any such instrument or writing may be proved by the
certificate of any public or other officer of any jurisdiction authorized to take
acknowledgments of deeds or administer oaths that the Person executing such instrument
acknowledged to such officer the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or other such officer, and where such
execution is by an officer of a corporation or association or of the Issuer, on behalf of
such corporation, association or the Issuer, such certificate or affidavit shall also
constitute sufficient proof of such Person’s authority.  The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the
same, may also be proved in any other manner which the Insurance Trustee deems sufficient.

    (c)     The ownership of
the Notes, the principal amount and serial numbers of Notes held by any Person and the
date or dates of holding the same shall be proved by the Note Register in accordance with
the Indenture and the Insurance Trustee shall not be affected by notice to the contrary.

    (d)     Any act of any
Noteholder (i) shall bind the holder of such Note and every future Noteholder of the same
Note and the Noteholder of every Note issued upon the transfer thereof or the exchange
therefor or in lieu thereof, whether or not notation of such action is made upon such
Note and whether or not such Noteholder has given its consent (unless required under this
Insurance) to such Act or was present at any duly held meeting, and (ii) shall be valid
notwithstanding that such Act is taken in connection with the transfer of such Note to
any other Person, including the Issuer or any Affiliate thereof.

    (e)     Until such time
as written instruments shall have been delivered with respect to the requisite percentage
of principal amount of Notes for the Act contemplated by such instruments, any such
instrument executed and delivered by or on behalf of a Noteholder may be revoked with
respect to any or all of such Notes by written notice by such Noteholder (or its duly
appointed agent) or any subsequent Noteholder (or its duly appointed agent), proven in
the manner in which such instrument was proven unless such instrument is by its terms
expressly irrevocable.

    (f)     For purposes of
this Agreement, Noteholder meetings shall be conducted in accordance with Article X and
other provisions of the Indenture including, without limitation, the determination of
whether the Noteholders’ requisite aggregate principal amount of Notes concurring for any
request, demand, authorization, direction, notice, consent and waiver or other act under
this Agreement.

    (g)     Subject to the
rights of the Insurer, if, under the terms of the Indenture, there is to be any vote of,
or consent or approval sought from, the holders of Covered Interest Period Amounts, the
Insurance Trustee will seek instruction from the Trust Beneficiaries in respect of such
vote, consent or approval and will only provide such vote, consent or approval as
instructed by the Trust Beneficiaries.

    Section 6.02.
Noteholder Lists. In accordance with Section 2.21 of the Indenture, the Indenture
Trustee shall preserve in as current form as is reasonably practicable the most recent
list available to it of the names and addresses of Noteholders and shall otherwise comply
with Section 312(a) of the Trust Indenture Act. If the Indenture Trustee is not the Note
Registrar, or to the extent otherwise required under the Trust Indenture Act, the Issuer
shall furnish to the Indenture Trustee, in writing at least seven Business Days before
each Interest Payment Date and at such other times as the Indenture Trustee may request
in writing, a list in such form and as of such date as the Indenture Trustee may
reasonably require of the names and addresses of the Noteholders, and the Issuer shall
otherwise comply with Section 312(a) of the Trust Indenture Act. The Indenture Trustee
shall, upon request by the Insurance Trustee, furnish a copy of such lists to the
Insurance Trustee pursuant to Section 2.21 of the Indenture; on the basis of the
information received from the Indenture Trustee, the Insurance Trustee shall maintain a
record of the record owners of interests in the Insurance Trust Property. 

ARTICLE VII

TERMINATION OF TRUST  

    Section 7.01.
Termination of the Trust. (a) The respective obligations and responsibilities of
the Issuer and the Insurance Trustee created hereby and the Insurance Trust created
hereby shall terminate upon the earliest of (i) repayment in full of the Notes in

provided, however, that in no event shall the Insurance Trust created hereby continue
beyond the expiration of 21 years from the death of the last survivor of the descendants
of George Herbert Walker Bush, former President of the United States, living on the date

    (b)     So long as no
claims were made under the Insurance Policy and the Insurer has no right in or with
respect to the Covered Interest Period Amounts at such time, upon termination of the
Insurance Trust, the Insurance Trustee on behalf of the Insurance Trust shall be deemed,
without the need of any further action, to have reassigned the Covered Interest Period
Amounts to the Noteholders.

Insurance Trustee shall be entitled to receive an Opinion of Counsel stating that such
amendment is permitted by this Agreement.

of any proposed amendment (except for any amendment agreed from time to time by the
Trustee and the Issuer pursuant to Section 8.02(a) hereof) at least 10 days prior to the

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). 

Article VI

Currency 

(1) (Place and Time of
Payment) Unless otherwise stipulated to the contrary, any and all payments to be made by
the Borrower to the LENDERS, the Agent and/or the Collection Agent under any Transaction

immediately available funds for value not later than 11:00 a.m. (Tokyo time) on the due
date for payment thereof to the account of the Collection Agent as is notified to the
Borrower by the Collection Agent. Any payment made on such due date but after that time
shall be deemed to have been made on the immediately following Business Day and

due on any day which is not a Business Day, such payment shall be made on the immediately

Free of Claims) Any repayment or payment or prepayment by the Borrower to the LENDERS
hereunder shall be made without set-off or counterclaim. 

(4) (Payments in

in Yen or the Relevant Currency, as the case may be, shall not be discharged or satisfied
by any amount, tender or recovery (whether pursuant to any judgment or otherwise)
expressed, paid or made in or converted into any currency other than Yen or the Relevant
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
amounts are due) pursuant to this Agreement;

due but unpaid under this Agreement, if any;

 (c) interest on Overdue Amounts due but
unpaid under this Agreement, if any;

the principal amount of the Loan then due and payable;

 (f) any amount due and
payable by the Borrower in accordance with the terms of this Agreement and not
otherwise provided for in this Section (5) of Article VI, 

provided that:

 (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.

between the Borrower and Sumitomo Mitsui Banking Corporation (the “Fee Letter”), at the
times specified for payment therein, independently from any obligation under this
Agreement.

Protection

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.

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 XIII
The 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.

Article XIV

This Agreement shall be governed by and construed in accordance with the laws of the
State of New York, without regard to the choice of law rules thereof, and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws. 

(2) (Good Faith
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
faith and mutual understanding, provided that such consultation shall not prejudice the
exercise of any right or remedy of either party hereto by any such party in respect of
any such dispute nor prevent a party from taking necessary steps to prevent the expiry of
any time limit for bringing any process, suit action or proceeding. 

(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
jurisdiction to       hear and determine any suit, action or proceedings, and to settle
any dispute, which may arise out of       or in connection with this Agreement and, for
such purpose, irrevocably submits to the jurisdiction       of such courts.

(b)   The Borrower
irrevocably waives any objection which it might at any time have to the courts referred
      to in paragraph (a) of this Section (3) being nominated as the forum to hear and
determine any suit,       action or proceedings, and to settle any disputes, which may
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
in       connection with such action or proceedings including, without limitation, the
making, enforcement or       execution against any property whatsoever (irrespective of
its use or intended use) of any order or       judgment which may be made or given in
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
      law of the Borrower’s Country, are deemed to provide an essential public service.

(4) (Process Agent)
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
Borrower by being delivered to (a) Abe & Matsutome Law Office at Shuwa Kioicho Park
Bldg., Suite 703, 3-6 Kioicho, Chiyoda-ku, Tokyo 102-0094, Japan (the “Tokyo Process Agent” and
(b) CT Corporation System at 111 Eighth Avenue, New York, NY 10011 USA (the “New York
Process Agent”).  

    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
the giving of relief by way of process of enforcement (including the arrest, detention or
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

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

Documents; provided that such agreement or instrument may provide that such LENDER will
not, without the consent of the Participant, agree to any amendment, modification or

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.

Participant or other transferee of any LENDER’s right shall be entitled to receive any

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.

the Agent in writing of such change and, at the same time, furnish to the Agent relevant
documentary evidence in respect of such change as well as authenticated specimen

Opinion of

	 	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 nima and 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 passu with 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.
