          SECTION 2. Partial Purchase Obligation. (a) In the event that, prior
to the Stated Maturity of the principal of the Notes, the Issuer shall fail to
make any payment on the Notes in respect of interest, principal or other amounts
as contemplated in the Indenture and/or the Notes (including, without
limitation, any Additional Amounts) on the date any such payment is due under
the terms of the Notes and the Indenture (other than in the case of an
acceleration thereof in accordance with the Indenture) (such date, the "Partial
Non-Payment Due Date"), then in such event (i) the Standby Purchaser shall be
obligated to pay immediately to the Trustee, for the benefit of the Noteholders
under the Indenture, the amount that the Issuer was required to pay but failed
to pay on such date under the terms of the Indenture and the Notes (the "Partial
Non-Payment Amount") and (ii) the Trustee shall provide notice to the Standby
Purchaser of the failure of the Issuer to make such payment; provided, however,
that the failure to provide such notice shall not in any way excuse the Standby
Purchaser from its obligations hereunder. The notice contemplated herein shall
be provided in writing in substantially the form of Exhibit A hereto (the
"Partial Non-Payment Notice") and shall be sent by the Trustee to the Standby
Purchaser at the address specified for the Standby Purchaser in Section 12
hereof no later than 5:00 p.m. (New York time) on the Partial Non-Payment Due
Date. The Partial Non-Payment Notice shall (i) confirm the Partial Non-Payment
Amount and the fact that such amount was not paid on the Partial Non-Payment Due
Date and (ii) remind the Standby Purchaser that it is obligated to pay the
Partial Non-Payment Amount immediately. To the extent that the Standby Purchaser
fails to pay the Partial Non-Payment Amount immediately pursuant to this Section
2(a) (whether or not it has received the Partial Non-Payment Notice), the
Standby Purchaser shall be obligated hereunder to pay, in addition to the
Partial Non-Payment Amount, interest on such amount at the Default Rate from the
Partial Non-Payment Due Date to and including the actual date of payment by the
Standby Purchaser (the "Partial Non-Payment Overdue Interest" and, together with
the Partial Non-Payment Amount, the "Partial Non-Payment Amount With Interest"),
which date of payment shall be a Business Day.

          (b) Payment of the Partial Non-Payment Amount With Interest shall be
in consideration of the purchase by the Standby Purchaser of the rights of the
Noteholders to receive such amount from the Issuer. The Noteholders shall have
no right to retain such rights, and, following the purchase and sale provided
for in this Section 2, the Notes shall remain outstanding with all amounts due
in respect thereof adjusted to reflect the purchase, sale and payment provided
for herein. Upon any such payment, the Standby Purchaser shall be subrogated to
the Noteholders to the extent of any payment under this Section 2.

          (c) The obligation of the Standby Purchaser to pay the Partial
Non-Payment Amount With Interest shall be absolute and unconditional upon
failure of the Issuer to make, prior to the Stated Maturity of the principal on
the Notes, any payment on the Notes in respect of interest, principal or other
amounts as contemplated in the Indenture and/or the Notes (including, without
limitation, any Additional Amounts) on the date any such payment is due. All
amounts payable by the Standby Purchaser hereunder in respect of any Partial
Non-Payment Amount With Interest shall be payable in U.S. dollars and in
immediately available funds to the Trustee at the account specified in Section
12 below, or to such other account as may be specified by the Trustee in the
applicable Partial Non-Payment Notice. The Standby Purchaser shall not be
relieved of its obligations hereunder unless and until the Trustee shall have
indefeasibly received all amounts required to be paid by it hereunder (and any
related Event of Default under the Indenture has been cured), including payment
of the Partial Non-Payment Overdue Interest as provided for herein.

          (d) All payments actually received by the Trustee pursuant to this
Section 2 after 1:00 p.m. (New York time) on any Business Day will be deemed,
for purposes of this Agreement, to have been received by the Trustee on the next
succeeding Business Day.

          SECTION 3. Total Purchase Obligation. (a) In the event that, at the
Stated Maturity of the principal on the Notes (or earlier upon any acceleration
thereof in accordance with the terms of the Indenture), the Issuer shall fail to
make any payment in respect of principal, interest or other amounts due under
the Indenture and the Notes on the date any such payment is so due (such date,
the "Total Non-Payment Due Date") then in such event, (i) the Standby Purchaser
shall be obligated to pay immediately to the Trustee, for the benefit of the
Noteholders under the Indenture, the amount that the Issuer was required to pay
but failed to pay on such date under the terms of the Notes and the Indenture
(the "Total Non-Payment Amount") and (ii) the Trustee shall provide notice to
the Standby Purchaser of the failure of the Issuer to make such payment,
provided, however, that the failure to provide such notice shall not in any way
excuse the Standby Purchaser from its obligations hereunder. The notice
contemplated herein shall be provided in writing in substantially the form of
Exhibit B hereto (the "Total Non-Payment Notice") sent to the Standby Purchaser
at the address specified for the Standby Purchaser in Section 12 hereof no later
than 5:00 p.m. (New York time) on the Total Non-Payment Due Date. The Total
Non-Payment Notice shall (i) confirm the amount of the Total Non-Payment Amount
and the fact that such amount was not paid on the Total Non-Payment Due Date and
(ii) remind the Standby Purchaser that it is obligated to pay the Total
Non-Payment Amount immediately. To the extent that the Standby Purchaser fails
to pay the Total Non-Payment Amount immediately when required pursuant to this
Section 3(a) (whether or not it has received the Total Non-Payment Notice), the
Standby Purchaser shall be obligated hereunder to pay, in addition to the
amounts specified above, interest on such amount at the Default Rate from the
Total Non-Payment Due Date to and including the actual date of payment by the
Standby Purchaser (the "Total Non-Payment Overdue Interest" and, together with
the Total Non-Payment Amount, the "Total Non-Payment Amount With Interest"),
which date of payment shall be a Business Day. Notwithstanding anything to the
contrary herein, the failure by the Trustee to deliver a Total Non-Payment
Notice as provided herein shall not release the Standby Purchaser of its
obligations to pay the Total Non-Payment Amount With Interest in the manner set
forth in this Section 3(a).

          (b) Payment of the Total Non-Payment Amount With Interest by the
Standby Purchaser shall be in consideration of the purchase by the Standby
Purchaser of the rights of the Noteholders to receive such amount from the
Issuer. The Noteholders shall have no right to retain such rights, and,
following the purchase and sale provided for in this Section 3, the Standby
Purchaser shall be subrogated to the Noteholders to the extent of any payment
under this Section 3.

          (c) The obligation of the Standby Purchaser to pay the Total
Non-Payment Amount With Interest shall be absolute and unconditional upon
failure of the Issuer to make, at the Stated Maturity of the principal of the
Notes (or earlier upon any acceleration thereof in accordance with the terms of
the Indenture), any payment in respect of principal, interest or other amounts
due under the Indenture and the Notes on the date any such payment is due. All
amounts payable by the Standby Purchaser hereunder in respect of any Total
Non-Payment Amount With Interest shall be payable in U.S. dollars and in
immediately available funds to the Trustee at the account specified in Section
12 below, or to such other account as may be specified by the Trustee in the
applicable Total Non-Payment Notice. The Standby Purchaser shall not be relieved
of its obligations hereunder unless and until the Trustee shall have received
all amounts required to be paid by it hereunder (and any related Event of
Default under the Indenture has been cured), including payment of the Total
Non-Payment Overdue Interest.

          (d) All payments actually received by the Trustee pursuant to this
Section 3 after 1:00 p.m. (New York time) on any Business Day will be deemed,
for purposes of this Agreement, to have been received by the Trustee on the next
succeeding Business Day.

          SECTION 4. Obligations Absolute. The Standby Purchaser's obligation to
pay one or more Partial Non-Payment Amounts With Interest or the Total
Non-Payment Amount With Interest (collectively, the "Purchase Obligations") are
absolute and unconditional regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of any Noteholder under its Notes or the Indenture. The Purchase
Obligations and the other obligations of the Standby Purchaser under or in
respect of this Agreement are independent of any obligations of the Issuer, the
Issuer's Subsidiaries or the Standby Purchaser's Subsidiaries under or in
respect of the Indenture and the Notes or any other document or agreement, and a
separate action or actions may be brought and prosecuted against the Standby
Purchaser to enforce this Agreement, irrespective of whether any action is
brought against the Issuer or whether the Issuer is joined in any such action or
actions. The liability of the Standby Purchaser under this Agreement shall be
irrevocable, absolute and unconditional irrespective of, and the Standby
Purchaser hereby irrevocably waives any defenses it may now have or hereafter
acquire in any way relating to, any or all of the following:

          (a) any lack of validity or enforceability of any of the Transaction
     Documents;

          (b) any provision of applicable Law or regulation purporting to
     prohibit the payment by the Standby Purchaser of any amount payable by it
     under this Agreement;

          (c) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Purchase Obligations or any other
     obligations of any other person or entity under or in respect of the
     Transaction Documents, or any other amendment or waiver of or any consent
     to departure from any Transaction Document, including, without limitation,
     any increase in the obligations of the Issuer under the Indenture and the
     Notes as a result of further issuances, any rescheduling of the Issuer's
     obligations under the Notes or the Indenture or otherwise;

          (d) any taking, release or amendment or waiver of, or consent to
     departure from, any other guaranty or agreement similar in function to this
     Agreement, for all or any of the obligations of the Issuer under the
     Indenture or the Notes;

          (e) any manner of sale or other disposition of any assets of any
     Noteholder;

          (f) any change, restructuring or termination of the corporate
     structure or existence of the Issuer or the Standby Purchaser or any
     Subsidiary thereof or any change in the name, purposes, business, capital
     stock (including ownership thereof) or constitutive documents of the Issuer
     or the Standby Purchaser;

          (g) any failure of the Trustee to disclose to the Standby Purchaser
     any information relating to the business, condition (financial or
     otherwise), operations, performance, properties or prospects of the Issuer
     or any of its Subsidiaries (the Standby Purchaser hereby waiving any duty
     on the part of the Trustee or any Noteholders to disclose such
     information);

          (h) the failure of any other person or entity to execute or deliver
     any other Guarantee or agreement or the release or reduction of liability
     of any other guarantor or surety with respect to the Indenture;

          (i) any other circumstance (including, without limitation, any statute
     of limitations) or any existence of or reliance on any representation by
     the Trustee or any Noteholder that might otherwise constitute a defense
     available to, or a discharge of, the Issuer or the Standby Purchaser or any
     other party; or

          (j) any claim of set-off or other right which the Standby Purchaser
     may have at any time against the Issuer or the Trustee, whether in
     connection with this transaction or with any unrelated transaction.

          This Agreement shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Purchase Obligations is
rescinded or must otherwise be returned by any Noteholder or any other person or
entity upon the insolvency, bankruptcy or reorganization of the Issuer or the
Standby Purchaser or otherwise, all as though such payment had not been made.

          SECTION 5. Independent Obligation. The obligations of the Standby
Purchaser hereunder are independent of the Issuer's obligations under the Notes
and the Indenture. The Trustee, on behalf of the Noteholders, may neglect or
forbear to enforce payment under the Indenture and the Notes, without in any way
affecting or impairing the liability of the Standby Purchaser hereunder. The
Trustee shall not be obligated to exhaust recourse or remedies against the
Issuer to recover payments required to be made under the Indenture nor take any
other action against the Issuer or, under any agreement, purchase any security
which the Trustee may hold before being entitled to payment from the Standby
Purchaser of all amounts contemplated in Sections 2 and 3 hereof owed hereunder
or proceed against or have resort to any balance of any deposit account or
credit on the books of the Trustee in favor of the Issuer or in favor of the
Standby Purchaser. Without limiting the generality of the foregoing, the Trustee
shall have the right to bring a suit directly against the Standby Purchaser,
either prior or subsequent to or concurrently with any lawsuit against, or
without bringing suit against, the Issuer.

          SECTION 6. Waivers and Acknowledgments. (a) The Standby Purchaser
hereby unconditionally and irrevocably waives promptness, diligence, notice of
acceptance, presentment, demand for performance, notice of nonperformance,
default, acceleration, protest or dishonor and any other notice with respect to
any of the Purchase Obligations and this Agreement and any requirement that the
Trustee, on behalf of the Noteholders, protect, secure, perfect or insure any
Lien or any property subject thereto or exhaust any right or take any action
against the Issuer or any other Person.

          (b) The Standby Purchaser hereby unconditionally and irrevocably
waives any right to revoke this Agreement and acknowledges that this Agreement
is continuing in nature and applies to its Purchase Obligations, whether the
same are existing now or in the future.

          (c) The Standby Purchaser hereby unconditionally and irrevocably
waives (i) any defense arising by reason of any claim or defense based upon an
election of remedies by any Noteholder or the Trustee on behalf of the
Noteholders that in any manner impairs, reduces, releases or otherwise adversely
affects the subrogation, reimbursement, exoneration, contribution or
indemnification rights of the Standby Purchaser or other rights of the Standby
Purchaser to proceed against the Issuer or any other person or entity and (ii)
any defense based on any right of set-off or counterclaim against or in respect
of the Purchase Obligations of the Standby Purchaser hereunder.

          (d) The Standby Purchaser hereby unconditionally and irrevocably
waives any duty on the part of the Trustee or any Noteholder to disclose to the
Standby Purchaser any matter, fact or thing relating to the business, condition
(financial or otherwise), operations, performance, properties or prospects of
the Issuer now or hereafter known by the Trustee or any Noteholder, as
applicable.

          (e) The Standby Purchaser acknowledges that it will receive
substantial direct and indirect benefits from the financing arrangements
contemplated by the Transaction Documents and that the waivers set forth in this
Section 6 are knowingly made in contemplation of such benefits.

          SECTION 7. Claims Against the Issuer. The Standby Purchaser hereby
unconditionally and irrevocably agrees not to exercise any rights that it may
now have or hereafter acquire against the Issuer or any other guarantor that
arise from the existence, payment, performance or enforcement of the Standby
Purchaser's Purchase Obligations under or in respect of this Agreement or any
other Transaction Document, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any
right to enforce any rights to payments in respect of the Partial Non-Payment
Amount With Interest and/or the Total Non-Payment Amount With Interest purchased
by the Standby Purchaser from the Noteholders as provided hereunder, or to
participate in any claim or remedy of the Trustee, on behalf of the Noteholders,
against the Issuer or any other person, whether or not such claim, remedy or
right arises in equity or under contract, statute or common law, including,
without limitation, the right to take or receive from the Issuer or any other
person, directly or indirectly, in cash or other property or by set-off or in
any other manner, payment or security on account of such claim, remedy or right,
unless and until all of the Purchase Obligations and all other amounts payable
under this Agreement shall have been paid in full in cash. If any amount shall
be paid to the Standby Purchaser in violation of the immediately preceding
sentence at any time prior to the later of (a) the payment in full in cash of
the Purchase Obligations and all other amounts payable under this Agreement and
(b) the date on which all of the obligations of the Issuer under the Indenture
and the Notes have been discharged in full (the later of such dates being the
"Termination Date"), such amount shall be received and held by the Trustee in
trust for the benefit of the Noteholders, shall be segregated from other
property and funds of the Standby Purchaser and shall forthwith be paid or
delivered to the Trustee in the same form as so received (with any necessary
endorsement or assignment) to be credited and applied to the Purchase
Obligations and all other amounts payable under this Agreement, whether matured
or unmatured, in accordance with the terms of the Indenture. If (i) the Standby
Purchaser shall make payment to any Noteholder or the Trustee, on behalf of the
Noteholders, of all or any part of the Purchase Obligations, (ii) all of the
Purchase Obligations and all other amounts payable under this Agreement shall
have been paid in full in cash and (iii) the Termination Date shall have
occurred, then the Trustee, on behalf of the Noteholders, will, at the Standby
Purchaser's request and expense, execute and deliver to the Standby Purchaser
appropriate documents, without recourse and without representation or warranty,
necessary to evidence the transfer by subrogation to the Standby Purchaser of an
interest in the Purchase Obligations resulting from such payment made by the
Standby Purchaser pursuant to this Agreement.

          SECTION 8. Payments Free and Clear of Taxes, Etc. (a) Any and all
payments by or on account of any obligation of the Standby Purchaser hereunder
or under any other Transaction Document shall be made free and clear of and
without deduction for any Indemnified Taxes; provided that if the Standby
Purchaser shall be required to deduct any Indemnified Taxes from such payments,
then (i) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional amounts
payable under this Section), the Trustee, on behalf of the Noteholders, receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) the Standby Purchaser shall make such deductions and (iii) the
Standby Purchaser shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable Law.

          (b) Payment of Other Taxes by the Standby Purchaser. In addition, the
Standby Purchaser shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable Law.

          (c) Notwithstanding anything to the contrary in Section 8(a) of this
Agreement, the Standby Purchaser will not be obligated to pay any Indemnified
Taxes imposed with respect to the Notes due to (i) the Noteholder or the Trustee
having a connection with the jurisdiction imposing the Indemnified Taxes
(hereinafter, the "Taxing Jurisdiction") other than from merely holding the
Notes or receiving principal or interest payments on the Notes (such as
citizenship, nationality, residence, domicile, or existence of a business, a
permanent establishment, a dependent agent, a place of business or a place of
management present or deemed present within the Taxing Jurisdiction), (ii) any
tax imposed on, or measured by, net income, (iii) the Noteholder or the Trustee
failing to comply with any certification, identification or other reporting
requirements concerning its nationality, residence, identity or connection with
the Taxing Jurisdiction, if (x) such compliance is required by applicable Law,
regulation, administrative practice or treaty as a precondition to exemption
from all or a part of the Indemnified Taxes, (y) the Noteholder or the Trustee
is able to comply with such requirements without undue hardship and (z) at least
30 calendar days prior to the first Payment Date with respect to which such
requirements under the applicable Law, regulation, administrative practice or
treaty shall apply, the Standby Purchaser has notified all the Noteholders or
the Trustee that they will be required to comply with such requirements, (iv)
the Noteholder or the Trustee failing to present (where presentation is
required) its Note within 30 calendar days after the Standby Purchaser has made
available to the Noteholder or the Trustee a payment under this Agreement;
provided that the Standby Purchaser will pay Indemnified Taxes which a
Noteholder or the Trustee would have been entitled to under such Note had it
been presented on any day (including the last day) within such 30 day period,
(v) any estate, inheritance, gift, value added, use or sales taxes or any
similar taxes, assessments or other governmental charges, (vi) such Indemnified
Taxes being imposed on a payment on the Notes to an individual and are required
to be made pursuant to European Union council Directive 2003/48/EC implementing
the conclusions of the Economic and Financial Council of Ministers of the member
states of the European Union (ECONFIN) Council meeting of November 26-27, 2000
on the taxation of savings income or any law implementing or complying with, or
introduced in order to conform to, any such Directive, (vii) such Note being
presented for payment by or on behalf of a Noteholder or Trustee who would have
been able to avoid such withholding or deduction by requesting that a payment on
the Notes be made by, or presenting the relevant Notes for payment to another
paying agent located in a member state of the European Union, or (viii) the
payment of any obligation of the Standby Purchaser to a Noteholder or Trustee
who would have been able to cause the avoidance of the Indemnified Taxes by
taking reasonable measures available to such Noteholder or the Trustee.

          The Standby Purchaser shall, if European Council Directive 2003/48/EC
or any other Directive implementing the conclusions of ECOFIN council meeting of
November 26-27, 2000 is brought into force, ensure that it maintains a paying
agent hereunder in a member state of the European Union that will not be obliged
to withhold or deduct tax pursuant to such Directive.

          (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Standby Purchaser to a Governmental
Authority, the Standby Purchaser shall deliver to the Trustee the original or a
certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of
such payment reasonably satisfactory to the Trustee.

          SECTION 9. Representations and Warranties. The Standby Purchaser makes
the following representations and warranties to the Trustee, on behalf of the
Noteholders, all of which shall survive the execution and delivery of this
Agreement:

the Standby Purchaser; each of this Agreement, the Third Supplemental Indenture
and each other document executed and delivered in connection therewith to which
the Standby Purchaser is party has been duly authorized and, assuming due
authorization, execution and delivery thereof by each other party to those
Transaction Documents (other than the Standby Purchaser), when executed and
delivered by the Standby Purchaser, will constitute a legal, valid and binding
agreement of the Standby Purchaser, enforceable against the Standby Purchaser in
accordance with its terms (subject, as to the enforcement of remedies, to
applicable bankruptcy, reorganization, insolvency, moratorium or other similar
laws affecting creditors' rights generally from time to time in effect and to
general principles of equity); and the descriptions of the Transaction Documents
in the Final Offering Document fairly summarize the rights and obligations of
the parties thereto.

Indenture, authenticated by the Trustee and delivered to and paid for by the

insolvency, moratorium, or other similar laws affecting creditors' rights
generally from time to time in effect and to general principles of equity and
will be entitled to the benefits provided by the Indenture as described in the
Registration Statement and the Final Offering Document.

          (r) The Notes will constitute the general unsecured and unsubordinated
obligations of the Issuer and will rank pari passu in priority of payment and in
right of seniority with all other unsecured and unsubordinated obligations of
the Issuer that are not, by their terms, expressly subordinated in right of
payment to the Notes, except for statutory liens and preferences. The
obligations of the Standby Purchaser under this Agreement will constitute the

violation of its charter, by-laws or comparable organizational documents;
neither the issuance and sale of the Notes, the execution and delivery of any of
the Transaction Documents or the consummation of any of the transactions
described or contemplated therein, or the fulfillment of the terms thereof will
conflict with, or give rise to any right to accelerate the maturity or require
the prepayment, repurchase or redemption of any indebtedness under, or result in
a breach or violation or imposition of any lien, charge or encumbrance upon any
property or assets of the Companies or any of their Material Subsidiaries
pursuant to, (i) the charter, by-laws or comparable organizational documents of
either of the Issuer or the Standby Purchaser or any of their Subsidiaries, (ii)

is subject or (iii) any statute, law, rule, regulation, judgment, order or
decree applicable to the Issuer or the Standby Purchaser or any of their
Subsidiaries, except in the case of clauses (ii) or (iii) such as could not
reasonably be expected to have a Material Adverse Effect.

          (z) Each of the Issuer and the Standby Purchaser and each of their
respective Subsidiaries has good and marketable title to all of their properties

such amounts as are prudent and customary in the businesses and in the
geographical regions in which they are engaged except when the failure to do so
would not have a Material Adverse Effect; and neither of the Issuer or the
Standby Purchaser nor any Subsidiary thereof has any reason to believe that it
will not be able to renew its existing insurance coverage as and when such
coverage expires or to obtain similar coverage from similar insurers as may be
necessary to continue its business at a cost that would not have a Material
Adverse Effect.

          (dd) No Subsidiary of the Issuer or the Standby Purchaser is currently

pollutants or contaminants, except in the case of clauses (i), (ii) and (iii)
above where such non-compliance with Environmental Laws, failure to receive
required permits, licenses or other approvals, or liability would not,
individually or in the aggregate, have a Material Adverse Effect. Except as set
forth in the Preliminary Offering Document and the Final Offering Document,
neither of the Issuer and the Standby Purchaser nor any of their Subsidiaries
has been named as a "potentially responsible party" under the United States
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,

as it may be contemplated in a bilateral treaty aimed at avoiding double
taxation between Brazil and such other country where the recipient of the
payment has its domicile. The Standby Purchaser is permitted to make all
payments pursuant to this Agreement free and clear of all taxes, levies,
imposts, deductions, charges or withholdings imposed, levied or made by or in
Brazil or any political subdivision or taxing authority thereof or therein, and
no such payment in the hands of the Trustee (to the extent that such payments
are for the benefit of non-residents of Brazil) or the Holders (that are
non-residents of Brazil) of the Notes will be subject to any tax, levy, impost,
deduction, charge or withholding imposed, levied or made by or in Brazil or any
political subdivision or taxing authority therein or thereof, in each case
except as provided in the immediately preceding sentence. The Standby Purchaser
intends to make all payments pursuant to this Agreement from funds offshore
Brazil. The Standby Purchaser does not believe or reasonably expect that any
interest paid or purchases of Purchase Obligations made by the Standby Purchaser
pursuant to the terms hereof will constitute interest paid by a trade or
business in the United States within the meaning of Section 884 (f) (1) (A) of
the Internal Revenue Code of 1986, as amended. To ensure the legality, validity,
enforceability or admissibility in evidence of this Agreement in Brazil, it is
not necessary that this Agreement or any other document be filed or recorded
with any court or other authority in Brazil, other than the notarization of the
signatures of the parties signing outside Brazil, the subsequent consularization
(authentication) of the signature of such a notary by a Brazilian consulate
official and the subsequent translation of this Agreement into Portuguese by a
sworn translator, or that any stamp or similar tax be paid on or in respect of
this Agreement or any of the other Transaction Documents.

          (uu) After being notarized, consularized and translated into
Portuguese by a sworn translator, this Agreement will be in proper legal form
under the laws of Brazil for the enforcement thereof in Brazil.

          (vv) To the extent the Standby Purchaser or its respective property
has or may in the future have any right of immunity, on the grounds of
sovereignty or otherwise, from any legal action, suit or proceeding, set-off or
counterclaim, the jurisdiction of any competent court, service of process,
attachment or execution, in any jurisdiction, with respect to its obligations,
liabilities, or any other matter under or arising out of or in connection with
this Agreement and any other Transaction Documents, the Standby Purchaser has
effectively waived such rights as provided in Section 18 hereof; provided that
no assets of the Standby Purchaser which are specifically used in the
furtherance of the activities listed in Article 177 of the Brazilian
Constitution, in respect of which the Brazilian government has a monopoly, could
be used by any person in Brazil acquiring such assets as a result of the
execution thereof in violation of the provisions contained in such Article 177
of the Brazilian Constitution. The execution and delivery of this Agreement by
the Standby Purchaser and the performance of its obligations hereunder by the
Standby Purchaser constitute private and commercial acts rather than
governmental or public acts.

          (ww) Except as described in the Final Offering Document and except as
to matters, individually or in the aggregate, which could not reasonably be
expected to have a Material Adverse Effect:

          (i) The Standby Purchaser and its Material Subsidiaries have obtained
     all environmental permits with respect to the business in which they are
     engaged and with respect to the facilities and properties owned, leased or
     operated by the Standby Purchaser or any of its Material Subsidiaries, and
     the business and all operations at the properties of the Standby Purchaser
     are in compliance with all environmental permits and are otherwise in
     compliance with all environmental laws;

          (ii) No officer of the Standby Purchaser or of any of its Material
     Subsidiaries has received any notice of any claim with respect to any of
     the properties, the business or otherwise, nor does the Standby Purchaser
     have knowledge or reason to believe that any such claim will be received or
     is threatened; and

          (iii) There are no past or present actions, activities, events,
     conditions or circumstances, including the release, threatened, release,
     emission, discharge, generation, treatment, storage or disposal of any
     hazardous materials at any locations, that would reasonably be expected to
     give rise to liability of the Standby Purchaser or any of its Material
     Subsidiaries under any law or any contract or agreement.

          (xx) The Standby Purchaser has, independently and without reliance
upon any Noteholder and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement and each other Transaction Document to which it is or is to be a
party, and the Standby Purchaser has established adequate means of obtaining
from the Issuer on a continuing basis information pertaining to, and is now and
on a continuing basis will be completely familiar with, the business, condition
(financial or otherwise), operations, performance, properties and prospects of
the Issuer.

          SECTION 10. Covenants

          For so long as the Notes remain outstanding or any amount remains
unpaid on the Notes and the Indenture, the Standby Purchaser will, and will
cause each of its Subsidiaries to, comply with the terms and covenants set forth
below (except as otherwise provided in a duly authorized amendment to this
Agreement as provided herein):

          (a) Performance of Obligations. The Standby Purchaser shall pay all
amounts owed by it and comply with all its other obligations under the terms of
this Agreement and the Indenture in accordance with the terms thereof.

          (b) Maintenance of Corporate Existence. The Standby Purchaser will,
and will cause each of its Subsidiaries to, (i) maintain in effect its corporate
existence and all registrations necessary therefor except as otherwise permitted
by Section 10(m) and (ii) take all actions to maintain all rights, privileges,
titles to property, franchises, concessions and the like necessary or desirable
in the normal conduct of its business, activities or operations; provided,
however, that this Section 10(b) shall not require the Standby Purchaser to
maintain or cause any Subsidiary thereof to maintain any such right, privilege,
title to property or franchise or require the Standby Purchaser to preserve the
corporate existence of any Subsidiary, if, in each case, the failure to do so
does not, and will not, have a Material Adverse Effect.

          (c) Maintenance of Properties. The Standby Purchaser will, and will
cause each of its Subsidiaries to, maintain and keep in good condition, repair
and working order (normal wear and tear excepted) all properties used or useful
in the conduct of its or its Subsidiaries businesses, and will, and will cause
each of its Subsidiaries to, make all necessary repairs, renewals, replacements
and improvements thereof, all as in the judgment of the Standby Purchaser shall
be necessary properly to conduct at all times the business carried on in
connection therewith; provided, that this Section 10(c) shall not require the
Standby Purchaser to maintain or cause any Subsidiary thereof to maintain any of
such properties if the failure to maintain such properties does not, and will
not, have a Material Adverse Effect.

          (d) Compliance with Laws and Agreements. The Standby Purchaser will
comply, and will cause its Subsidiaries to comply, at all times in all material
respects with all applicable Laws (including, without limitation, Environmental
Laws), rules, regulations, orders and directives of any Governmental Authority
having jurisdiction over the Standby Purchaser and each Subsidiary thereof or
their businesses or any of the transactions contemplated herein. The Standby
Purchaser will also comply, and will cause its Subsidiaries to comply, with all
covenants and other obligations contained in any agreements to which they are a
party, except where the failure so to comply would not have a Material Adverse
Effect.

          (e) Maintenance of Governmental Approvals. The Standby Purchaser will,
and will cause its Subsidiaries to, duly obtain and maintain in full force and
effect all approvals of Governmental Authorities and third parties, consents or
licenses which are necessary under the laws of Brazil, the Cayman Islands or any
other jurisdiction having jurisdiction over the Standby Purchaser and each
Subsidiary thereof in connection with the execution, delivery and performance of
this Agreement and each other Transaction Document by the Standby Purchaser or
the validity or enforceability of any thereof.

          (f) Payments of Taxes and Other Claims. The Standby Purchaser will,
and will cause each of its Subsidiaries to, pay or discharge or cause to be paid
or discharged, before the same shall become delinquent, (i) all taxes,
assessments and governmental charges levied or imposed upon the Standby
Purchaser or such Subsidiary, as the case may be, and (ii) all lawful claims for
labor, materials and supplies which, if unpaid, might by law become a lien upon
the property of the Standby Purchaser or such Subsidiary, as the case may be;
provided, however, that this Section 10(f) shall not require the Standby
Purchaser to, or to cause any Subsidiary thereof to, pay or discharge or cause
to be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith and, if appropriate,
by appropriate legal proceedings or where the failure to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim would
not have a Material Adverse Effect.

          (g) Maintenance of Ownership of the Issuer. For so long as any Notes
are outstanding, the Standby Purchaser will retain no less than 51% direct or
indirect ownership of the outstanding voting and economic interests (equity or
otherwise) of and in the Issuer.

          (h) Maintenance of Insurance. The Standby Purchaser will, and will
cause each of its Subsidiaries to, maintain insurance with insurance companies
that the Standby Purchaser reasonably believes to be financially sound in such
amounts and covering such risks as are usually carried by companies engaged in
similar businesses and owning or operating properties or facilities similar to
those owned and operated by the Standby Purchaser or its Subsidiaries, as the
case may be, in the same general areas in which the Standby Purchaser and its
Subsidiaries own or operate their properties or facilities, except where the
failure to do so would not have a Material Adverse Effect.

          (i) Maintenance of Books and Records. The Standby Purchaser shall, and
shall cause each of its Material Subsidiaries to, maintain books, accounts and
records in accordance with U.S. GAAP, in the case of the Standby Purchaser and
the Issuer, and, in the case of each other Subsidiary of the Standby Purchaser,
generally accepted accounting principles in the jurisdiction where each such
Subsidiary is organized.

          (j) Maintenance of Office or Agency. So long as any of the Notes are
outstanding, the Standby Purchaser will maintain in the Borough of Manhattan,
The City of New York, an office or agency where notices to and demands upon the
Standby Purchaser in respect of this Agreement may be served, and the Standby
Purchaser will not change the designation of such office without prior notice to
the Trustee and designation of a replacement office in the same general
location.

          (k) Ranking. The Standby Purchaser will ensure at all times that its
obligations under this Agreement will constitute the general senior unsecured
and unsubordinated obligations of the Standby Purchaser and will rank pari
passu, without any preferences among themselves, with all other present and
future senior unsecured and unsubordinated obligations of the Standby Purchaser
(other than obligations preferred by statute or by operation of law) that are
not, by their terms, expressly subordinated in right of payment to the
obligations of the Standby Purchaser under this Agreement.

          (l) Notice of Defaults. The Standby Purchaser will give written notice
to the Trustee, as soon as is practicable and in any event within ten calendar
days after the Standby Purchaser becomes aware, or should reasonably become
aware, of the occurrence of any Default or any Event of Default, accompanied by
a certificate of an officer of the Standby Purchaser setting forth the details
thereof and stating what action the Standby Purchaser proposes to take with
respect thereto.

          (m) Limitation on Consolidation, Merger, Sale or Conveyance. (i) The
Standby Purchaser will not, in one or a series of transactions, consolidate or
amalgamate with or merge into any corporation or convey, lease or transfer
substantially all of its properties, assets or revenues to any person or entity
(other than a direct or indirect Subsidiary of the Standby Purchaser) or permit
any person or entity (other than a direct or indirect Subsidiary of the Standby
Purchaser) to merge with or into it, unless:

          (A) either the Standby Purchaser is the continuing entity or the
     person (the "Successor Company") formed by such consolidation or into which
     the Standby Purchaser is merged or that acquired or leased such property or
     assets of the Standby Purchaser will be a corporation organized and validly
     existing under the laws of Brazil and shall assume (jointly and severally
     with the Standby Purchaser unless the Standby Purchaser shall have ceased
     to exist as a result of such merger, consolidation or amalgamation), by an
     amendment to this Agreement (the form and substance of which shall be
     previously approved by the Trustee), all of the Standby Purchaser's
     obligations under this Agreement;

          (B) the Successor Company (jointly and severally with the Standby
     Purchaser unless the Standby Purchaser shall have ceased to exist as part
     of such merger, consolidation or amalgamation) agrees to indemnify each
     Noteholder against any tax, assessment or governmental charge thereafter
     imposed on such Noteholder solely as a consequence of such consolidation,
     merger, conveyance, transfer or lease with respect to the payment of
     principal of, or interest on, the Notes;

          (C) immediately after giving effect to such transaction, no Event of
     Default and no Default has occurred and is continuing;

          (D) the Standby Purchaser has delivered to the Trustee an Officer's
     Certificate and an Opinion of Counsel each stating that such merger
     consolidation, sale, transfer or other conveyance or disposition and the
     amendment to this Agreement comply with the terms of this Agreement and
     that all conditions precedent provided for herein and relating to such
     transaction have been complied with; and

          (E) the Standby Purchaser has delivered notice of any such transaction
     to Moody's (which notice shall contain a description of such merger,
     consolidation or conveyance).

          (ii) Notwithstanding anything to the contrary in the foregoing, so
long as no Default or Event of Default shall have occurred and be continuing at
the time of such proposed transaction or would result therefrom and the Standby
Purchaser has delivered notice of any such transaction to Moody's and the
Trustee (which notice shall contain a description of such merger, consolidation
or conveyance):

          (A) the Standby Purchaser may merge, amalgamate or consolidate with or
     into, or convey, transfer, lease or otherwise dispose of all or
     substantially all of its properties, assets or revenues to a direct or
     indirect Subsidiary of the Standby Purchaser in cases when the Standby
     Purchaser is the surviving entity in such transaction and such transaction
     would not have a material adverse effect on the Standby Purchaser and its
     Subsidiaries taken as a whole, it being understood that if the Standby
     Purchaser is not the surviving entity, the Standby Purchaser shall be
     required to comply with the requirements set forth in the previous
     paragraph; or

          (B) any direct or indirect Subsidiary of the Standby Purchaser may
     merge or consolidate with or into, or convey, transfer, lease or otherwise
     dispose of assets to, any person (other than the Standby Purchaser or any
     of its Subsidiaries or Affiliates) in cases when such transaction would not
     have a material adverse effect on the Standby Purchaser and its
     Subsidiaries taken as a whole; or

          (C) any direct or indirect Subsidiary of the Standby Purchaser may
     merge or consolidate with or into, or convey, transfer, lease or otherwise
     dispose of assets to, any direct or indirect Subsidiary of the Standby
     Purchaser; or

          (D) any direct or indirect Subsidiary of the Standby Purchaser may
     liquidate or dissolve if the Standby Purchaser determines in good faith
     that such liquidation or dissolution is in the best interests of the
     Standby Purchaser, and would not result in a material adverse effect on the
     Standby Purchaser and its Subsidiaries taken as a whole and if such
     liquidation or dissolution is part of a corporate reorganization of the
     Standby Purchaser.

          (n) Negative Pledge. So long as any Note remains outstanding, the
Standby Purchaser will not create or permit any Lien, other than a Permitted
Lien, on any of the Standby Purchaser's assets to secure (i) any of the Standby
Purchaser's Indebtedness or (ii) the Indebtedness of any other person, unless
the Standby Purchaser contemporaneously creates or permits such Lien to secure
equally and ratably the Standby Purchaser's obligations under this Agreement or
the Standby Purchaser provides such other security for the Notes as is duly
approved by the Trustee, at the direction of the Noteholders, in accordance with
the Indenture. In addition, the Standby Purchaser will not allow any of the
Standby Purchaser's Subsidiaries to create or permit any Lien, other than a
Permitted Lien, on any of the Standby Purchaser's assets to secure (i) any of
the Standby Purchaser's Indebtedness, (ii) any of the Indebtedness of the
Standby Purchaser's Subsidiaries or (iii) the Indebtedness of any other person,
unless it contemporaneously creates or permits the Lien to secure equally and
ratably the Standby Purchaser's obligations under this Agreement or the Standby
Purchaser or such Subsidiary provides such other security for the Notes as is
duly approved by the Trustee, at the direction of the Noteholders, in accordance
with the Indenture.

          (o) Transactions with Affiliates. The Standby Purchaser shall not, and
shall not permit any of its Subsidiaries to, enter into or carry out (or agree
to enter into or carry out) any transaction or arrangement with any Affiliate,
except for any transaction or arrangement entered into or carried out on terms
no less favorable to the Standby Purchaser or such Subsidiary than those which
could have been obtained on an arm's-length basis with a person that is not an
Affiliate, provided, however, that the foregoing shall not apply to transactions
(i), between the Standby Purchaser and the Issuer or any Subsidiary of the
Issuer or (ii) except as otherwise permitted pursuant to clause (i), between or
among the Standby Purchaser, the Issuer and any of their respective Subsidiaries
not involving any other person so long as consummation of any such transaction
described in this clause (ii) will not have a Material Adverse Effect.

          (p) Provision of Financial Statements and Reports. (i) The Standby
Purchaser will provide to the Trustee, in English or accompanied by a certified
English translation thereof, (A) within 90 calendar days after the end of each
fiscal quarter (other than the fourth quarter), its unaudited and consolidated
balance sheet and statement of income calculated in accordance with U.S. GAAP,
(B) within 120 calendar days after the end of each fiscal year, its audited and
consolidated balance sheet and statement of income calculated in accordance with
U.S. GAAP and (C) such other financial data as the trustee may reasonably
request.

          (ii) The Standby Purchaser will provide, together with each of the
     financial statements delivered pursuant to Sections 10(p)(i)(A) and (B), an
     Officers' Certificate stating that a review of the activities of the
     Standby Purchaser and the Issuer has been made during the period covered by
     such financial statements with a view to determining whether the Standby
     Purchaser and the Issuer have kept, observed, performed and fulfilled their
     covenants and agreements under this Agreement and the Indenture, as
     applicable, and that no Default or Event of Default has occurred during
     such period or, if one or more have actually occurred, specifying all such
     events and what actions have been taken and will be taken with respect to
     such Default or Event of Default.

          (iii) The Standby Purchaser shall, whether or not it is required to
     file reports with the SEC, file with the SEC and deliver to the Trustee
     (for redelivery to all Noteholders) all reports and other information as it
     would be required to file with the SEC under the Exchange Act if it were
     subject to those regulations; provided, however, that if the SEC does not
     permit the filing described in the first sentence of this Section
     10(q)(iii), the Standby Purchaser will provide annual and interim reports
     and other information to the Trustee within the same time periods that
     would be applicable if the Standby Purchaser were required and permitted to
     file these reports with the SEC.

          (q) Further Actions. The Standby Purchaser will, at its own cost and
expense, and will cause its Subsidiaries to, at their own cost and expense, take
any action, satisfy any condition or take any action (including the obtaining or
effecting of any necessary consent, approval, authorization, exemption, filing,
license, order, recording or registration) at any time required, in the
reasonable opinion of the Trustee, in accordance with applicable Laws (as
applicable) to be taken, fulfilled or done in order to (i) enable the Standby
Purchaser to lawfully enter into, exercise its rights and perform and comply
with its obligations under this Agreement and each of the other Transaction
Documents to which it is a party, as the case may be, (ii) ensure that the
Standby Purchaser's obligations under this Agreement and each of the other
Transaction Documents are legally binding and enforceable, (iii) make this
Agreement and each of the other Transaction Documents admissible in evidence in
the courts of the State of New York, Brazil or the Cayman Islands, (iv) enable
the Trustee to exercise and enforce its rights under and carry out the terms,
obligations, provisions and purposes of this Agreement and each of the other
Transaction Documents, (v) take any and all action necessary to preserve the
enforceability of, and maintain the Trustee's rights under this Standby Purchase
Agreement and the other Transaction Documents, including, without limitation,
refraining from taking any action that reasonably can be expected to have an
adverse effect on the enforceability of, or any of the Trustee's rights under,
this Agreement and the other Transaction Documents, and (vi) assist the Trustee
in the Trustee's performance of its obligations under this Agreement and the
other Transaction Documents; provided, however, that the Standby Purchaser shall
not be required to take any action contemplated herein if it promptly (and in no
event later than two Business Days after any such request) provides to the
Trustee a written opinion from counsel reasonably acceptable to the Trustee
specifying that the failure to take such action or satisfy such condition would
not have an adverse effect on the rights of the Noteholders.

          (r) Importation of Oil and Oil Products. The Standby Purchaser shall,
in each calendar year, purchase from the Issuer not less than 80% (on a United
States dollar value) of the oil and oil product it imports.

          SECTION 11. Amendments, Etc. No amendment or waiver of any provision
of this Agreement and no consent to any departure by the Standby Purchaser
therefrom shall in any event be effective unless the same shall be in writing
and signed by the Trustee and the Standby Purchaser, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given.

          SECTION 12. Notices, Etc. (a) All notices and other communications
provided for hereunder shall be in writing (including telegraphic or telecopy)

          (b) All payments made by the Standby Purchaser to the Trustee
hereunder shall be made to the Payment Account (as defined in the Indenture),
except to the extent otherwise specified in a Partial Non-Payment Notice or
Total Non-Payment Notice.

          SECTION 13. No Waiver; Remedies. No failure on the part of the Trustee
to exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

          SECTION 14. Indemnification. (a) Without limitation on any other
obligations of the Standby Purchaser or remedies of the Trustee under this
Agreement, the Standby Purchaser shall, to the fullest extent permitted by law,
indemnify, defend and save and hold harmless the Trustee and its officers,
directors, employees, agents and advisors (each, an "Indemnified Party") from
and against, and shall pay on demand, any and all claims, damages, losses,
liabilities and expenses (including, without limitation, reasonable fees and
expenses of counsel) that may be incurred by or asserted or awarded against any
Indemnified Party in connection with or as a result of any failure of any
Purchase Obligation to be the legal, valid and binding obligations of the
Standby Purchaser enforceable against it in accordance with their terms.

          (b) The Standby Purchaser hereby also agrees that none of the
Indemnified Parties shall have any liability (whether direct or indirect, in
contract, tort or otherwise) to the Standby Purchaser or any of its Affiliates
or any of their respective officers, directors, employees, agents and advisors,
and the Standby Purchaser hereby agrees not to assert any claim against any
Indemnified Party on any theory of liability, for special, indirect,
consequential or punitive damages arising out of or otherwise relating to the
Transaction Documents or any of the transactions contemplated by the Transaction
Documents.

          (c) Without prejudice to the survival of any of the other agreements
of the Standby Purchaser under this Agreement or any of the other Transaction
Documents, the agreements and obligations of the Standby Purchaser contained in
Sections 2 and 3 (with respect to the payment of all other amounts owed under
the Indenture), Section 9 and this Section 14 shall survive the payment in full
of the Purchase Obligations and all of the other amounts payable under this
agreement.

          SECTION 15. Subordination. To the extent that the Standby Purchaser is
required to make any payment hereunder, the Standby Purchaser hereby
subordinates any and all debts, liabilities and other obligations owed by the
Issuer to the Standby Purchaser (the "Subordinated Obligations") to the Purchase
Obligations and agrees that it shall not require the Issuer to make any payments
in respect thereof to the extent and in the manner hereinafter set forth in this
Section 15:

          (a) Prohibited Payments, Etc. Except during the continuance of a
Default or Event of Default (including the commencement and continuation of any
proceeding under any applicable bankruptcy, insolvency, receivership or similar
law now or hereafter in effect relating to the Issuer (each such law, a
"Bankruptcy Law")), the Standby Purchaser may receive any payments from the
Issuer on account of the Subordinated Obligations. After the occurrence and
during the continuance of any Default (including the commencement and
continuation of any proceeding under any Bankruptcy Law relating to the Issuer),
however, unless the Trustee otherwise agrees, the Standby Purchaser shall not
demand, accept or take any action to collect any payment on account of the
Subordinated Obligations.

          (b) Prior Payment of Purchase Obligations. In any proceeding under any
Bankruptcy Law relating to the Issuer, the Standby Purchaser agrees that the
Trustee, on behalf of the Noteholders, shall be entitled to receive payment in
full in cash of all Purchase Obligations (including all interest and expenses
accruing after the commencement of a proceeding under any Bankruptcy Law,
whether or not constituting an allowed claim in such proceeding ("Post Petition
Interest")) before the Standby Purchaser receives payment of any Subordinated
Obligations.

          (c) Turn-Over. After the occurrence and during the continuance of any
Default (including the commencement and continuation of any proceeding under any
Bankruptcy Law relating to the Issuer), the Standby Purchaser shall, if the
Trustee, on behalf of the Noteholders, so requests, collect, enforce and receive
payments on account of the Subordinated Obligations as trustee for the Trustee
and deliver such payments to the Trustee, on behalf of the Noteholders, on
account of the Purchase Obligations (including all Post Petition Interest),
together with any necessary endorsements or other instruments of transfer, but
without reducing or affecting in any manner the liability of the Standby
Purchaser under the other provisions of this Agreement.

          (d) Trustee Authorization. After the occurrence and during the
continuance of any Default (including the commencement and continuation of any
proceeding under any Bankruptcy Law relating to any of the Issuer, any Material
Subsidiary thereof or any Material Subsidiary of the Standby Purchaser), the
Trustee, at the direction of the Noteholders or otherwise, is authorized and
empowered (but without any obligation to so do), in its discretion, (i) in the
name of the Standby Purchaser, to collect and enforce, and to submit claims in
respect of, Subordinated Obligations and to apply any amounts received thereon
to the Purchase Obligations (including any and all Post Petition Interest), and
(ii) to require the Standby Purchaser (A) to collect and enforce, and to submit
claims in respect of, Subordinated Obligations and (B) to pay any amounts
received on such obligations to the Trustee for application to the Purchase
Obligations (including any and all Post Petition Interest).

          SECTION 16. Continuing Agreement; Assignment of Rights Under the
Indenture and the Notes. This Agreement is a continuing Purchase Obligation and
shall (a) remain in full force and effect until the later of (i) the repayment
in full by the Issuer of all amounts due and owing under the Indenture with
respect to the Notes and (ii) the repayment in full of all Purchase Obligations
and all other amounts payable under this Agreement, (b) be binding upon the
Standby Purchaser, its successors and assigns and (c) inure to the benefit of
and be enforceable by the Trustee, on behalf of Noteholders, and their
successors, transferees and assigns. Without limiting the generality of clause
(c) of the immediately preceding sentence, any Noteholder may assign or
otherwise transfer all or any portion of its rights and obligations under the
Indenture (including, without limitation, the Note or Notes held by it) to any
other person or entity (subject to the rights of the Standby Purchaser hereunder
in respect of any Partial Non-Payment Amount With Interest or Total Non-Payment
Amount With Interest as provided herein), and such other person or entity shall
thereupon become vested with all the benefits in respect thereof granted to such
Noteholder herein or otherwise, in each case as and to the extent provided in
the Indenture. The Standby Purchaser shall not have the right to assign its
rights hereunder or any interest herein without the prior written consent of all
of the Noteholders.

          SECTION 17. Currency Rate Indemnity. (a) The Standby Purchaser shall
(to the extent lawful) indemnify the Trustee and the Noteholders and keep them
indemnified against:

          (i) in the case of nonpayment by the Standby Purchaser of any amount
     due to the Trustee, on behalf of the Noteholders, under this Agreement any
     loss or damage incurred by any of them arising by reason of any variation
     between the rates of exchange used for the purposes of calculating the
     amount due under a judgment or order in respect thereof and those
     prevailing at the date of actual payment by the Standby Purchaser; and

          (ii) any deficiency arising or resulting from any variation in rates
     of exchange between (a) the date as of which the local currency equivalent
     of the amounts due or contingently due under this Agreement or in respect
     of the Notes is calculated for the purposes of any bankruptcy, insolvency
     or liquidation of the Standby Purchaser, and (b) the final date for
     ascertaining the amount of claims in such bankruptcy, insolvency or
     liquidation. The amount of such deficiency shall be deemed not to be
     increased or reduced by any variation in rates of exchange occurring
     between the said final date and the date of any bankruptcy, insolvency or
     liquidation or any distribution of assets in connection therewith.

          (b) The Standby Purchaser agrees that, if a judgment or order given or
made by any court for the payment of any amount in respect of its Purchase
Obligation hereunder is expressed in a currency (the "Judgment Currency") other
than U.S. dollars (the "Denomination Currency"), it will indemnify the relevant
holder against any deficiency arising or resulting from any variation in rates
of exchange between the date at which the amount in the Denomination Currency is
notionally converted into the amount in the Judgment Currency for the purposes
of such judgment or order and the date of actual payment thereof.

          (c) The above indemnities shall constitute separate and independent
obligations of the Standby Purchaser from its obligations hereunder, will give
rise to separate and independent causes of action, will apply irrespective of
any indulgence granted from time to time and will continue in full force and
effect notwithstanding any judgment or the filing of any proof or proofs in any
bankruptcy, insolvency or liquidation of the Standby Purchaser for a liquidated
sum or sums in respect of amounts due under this Agreement, or under the
Indenture or the Notes or under any judgment or order.

          SECTION 18. Governing Law; Jurisdiction; Waiver of Immunity, Etc. (a)
This Agreement shall be governed by, and construed in accordance with, the laws
of the State of New York.

          (b) The Standby Purchaser hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of any
New York State court or federal court of the United States of America sitting in
New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement or any of the other
Transaction Documents to which it is or is to be a party, or for recognition or
enforcement of any judgment, and the Standby Purchaser hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in any such New York State court or, to
the extent permitted by law, in such federal court. The Standby Purchaser agrees
that a final judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law. Nothing in this Agreement or any other Transaction
Document shall affect any right that any party may otherwise have to bring any
action or proceeding relating to this Agreement or any other Transaction
Document in the courts of any jurisdiction.

          (c) The Standby Purchaser hereby irrevocably appoints and empowers the
New York office of Petroleo Brasileiro S.A., located at 570 Lexington Avenue,
43rd Floor, New York, New York 10022 as its authorized agent (the "Process
Agent") to accept and acknowledge for and on its behalf and on behalf of its
property service of any and all legal process, summons, notices and documents
which may be served in any such suit, action or proceedings in any New York
State court or United States federal court sitting in the State of New York in
the Borough of Manhattan and any appellate court from any thereof, which service
may be made on such designee, appointee and agent in accordance with legal
procedures prescribed for such courts. The Standby Purchaser will take any and
all action necessary to continue such designation in full force and effect and
to advise the Trustee of any change of address of such Process Agent and should
such Process Agent become unavailable for this purpose for any reason, the
Standby Purchaser will promptly and irrevocably designate a new Process Agent
within New York, New York, which will agree to act as such, with the powers and
for the purposes specified in this subsection (c). The Standby Purchaser
irrevocably consents and agrees to the service of any and all legal process,
summons, notices and documents out of any of the aforesaid courts in any such
action, suit or proceeding by hand delivery, to it at its address set forth in
Section 12 or to any other address of which it shall have given notice pursuant
to Section 12 or to its Process Agent. Service upon the Standby Purchaser or the
Process Agent as provided for herein will, to the fullest extent permitted by
law, constitute valid and effective personal service upon it and the failure of
the Process Agent to give any notice of such service to the Standby Purchaser
shall not impair or affect in any way the validity of such service or any
judgment rendered in any action or proceeding based thereon.

          (d) The Standby Purchaser irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection that it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or any of the other
Transaction Documents to which it is or is to be a party in any New York State
or federal court. The Standby Purchaser hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such suit, action or proceeding in any such court.

          (e) THE STANDBY PURCHASER HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT,
TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY OF THE TRANSACTION
DOCUMENTS, THE ADVANCES OR THE ACTIONS OF ANY NOTEHOLDER IN THE NEGOTIATION,
ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

          (f) This Agreement and any other documents delivered pursuant hereto,
and any actions taken hereunder, constitute commercial acts by the Standby
Purchaser. The Standby Purchaser irrevocably and unconditionally and to the
fullest extent permitted by law, waives, and agrees not to plead or claim, any
immunity from jurisdiction of any court or from any legal process (whether
through service of notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) for itself, the Issuer or any of their
property, assets or revenues wherever located with respect to its obligations,
liabilities or any other matter under or arising out of or in connection with
this Agreement or any document delivered pursuant hereto, in each case for the
benefit of each assigns, it being intended that the foregoing waiver and
agreement will be effective, irrevocable and not subject to withdrawal in any
and all jurisdictions, and, without limiting the generality of the foregoing,
agrees that the waivers set forth in this subsection (f) shall have the fullest
scope permitted under the United States Foreign Sovereign Immunities Act of 1976
and are intended to be irrevocable for the purposes of such act.

          SECTION 19. Execution in Counterparts. This Agreement and each
amendment, waiver and consent with respect hereto may be executed in any number
of counterparts and by different parties thereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement. Delivery of an
executed counterpart of a signature page to this Agreement by telecopier shall
be effective as delivery of an original executed counterpart of this Agreement.

          SECTION 20. Pledge of Interests. (a) The Standby Purchaser hereby
pledges to the Trustee (for the benefit of the Noteholders) and grants a
continuing security interest in, all of its interest (if any) in (a) the Payment
Account, (b) all funds from time to time on deposit in the Payment Account, (c)
all interest, dividends, distributions, cash, instruments and other property
from time to time received, receivable or on deposit in the Payment Account, and
(d) all proceeds of any of the foregoing (together, the "Collateral"). The
Standby Purchaser agrees to take all such action as is required by applicable
Law or as the Trustee may require, including delivering Opinions of Counsel in
form and substance acceptable to the Trustee, as to the grant and perfection of
the foregoing security interests.

          (b) The security interest granted in the Collateral, shall secure the
payment of all obligations of the Standby Purchaser now or hereafter existing
under the Transaction Documents, whether direct or indirect, absolute or
contingent, and whether for principal, reimbursement obligations, interest,
fees, premiums, penalties, indemnifications, contract causes of action, costs,
expenses or otherwise. The Standby Purchaser represents and warrants that it has
not heretofore pledged, conveyed, granted a lien on, or security interest in, or
otherwise encumbered any of the Collateral in favor of any Person under U.S.,
Cayman, Brazilian or other Law.

          SECTION 21. Entire Agreement. This Agreement, together with the
Indenture and the Notes, sets forth the entire agreement of the parties hereto
with respect to the subject matter hereof.



          IN WITNESS WHEREOF, the Standby Purchaser has caused this Agreement to
be duly executed and delivered by its officer thereunto duly authorized as of

               constitutes a Partial Non-Payment Notice as contemplated in the
               Standby Purchase Agreement.

          2.   Pursuant to the Standby Purchase Agreement, you are obligated to
               purchase from the holders of the Notes their right to receive the

          3.   Pursuant to the Standby Purchase Agreement, you are hereby
               directed to purchase the right of the holders of the Notes to

               on behalf of the holders of the Notes, in partial satisfaction of
               your obligation to purchase the right to Overdue Amount.

          4.   You are hereby directed to pay immediately the Overdue Amount to
