                                   TRUST DEED

         THIS AMENDED AND RESTATED TRUST DEED dated December 21, 2001 (this
"Trust Deed") is made by and among U.S. Bank, National Association, Cayman
Islands Branch, with its specified office, on the date of this Trust Deed,
located at c/o IBJ Whitehall Bank and Trust Company, P.O. Box 1040 GT, Grand
Cayman, Cayman Islands, British West Indies, in its capacity as trustee of the
Trust (as defined herein) (in such capacity and together with its successors and
assigns in such capacity, the "Trustee"); Citibank, N.A., a national banking
association organized under the laws of the United States of America, in its
capacity as Registrar, Paying Agent, Transfer Agent and Depositary Bank (in each
such capacity and together with its successors and assigns in each such
capacity, the "Registrar," the "Paying Agent," the "Transfer Agent" and the
"Depositary Bank"); and Petrobras International Finance Company, a wholly-owned
subsidiary of Petrobras, in its capacity as Servicer (in such capacity and
together with its successor and assigns in such capacity, the "Servicer").

                              PRELIMINARY STATEMENT

         The Trustee has received the sum of U.S.$1,000 (the "Initial Settled
Sum") and hereby declares the trusts over which this and other property is to be
held.

         The Trustee has duly authorized due execution and delivery of this
Trust Deed to provide for the issuance of senior trust certificates (the "Senior
Trust Certificates") and junior trust certificates (the "Junior Trust
Certificates" and, together with the Senior Trust Certificates, the "Trust
Certificates") as provided in this Trust Deed, from time to time, and in one or
more series, in an unlimited aggregate principal amount, subject to the terms
and conditions provided in this Trust Deed.

         The Trust Certificates are issued by U.S. Bank, National Association,
Cayman Islands Branch only in its capacity as Trustee, and not otherwise. The
interests of the Certificate Holders and the obligations of the Trustee in
respect of the Trust Certificates are limited solely to payments received from
the assets of the Trust. The Certificate Holders shall not have recourse to the
assets of U.S. Bank, National Association, Cayman Islands Branch in its
individual or personal capacity.

         Payments in respect of any beneficial interest represented by a Trust
Certificate are payable as provided in this Trust Deed.

         This Amended and Restated Trust Deed hereby amends and restates the
Trust Deed dated December 7, 2001 made by the Trustee in its capacity as trustee
of the Trust. Capitalized terms used but not defined herein have the meanings
ascribed thereto in Section 1.01 hereof, whether by cross-reference or
otherwise.

                              DECLARATION OF TRUST

         (a) The trust constituted by this Trust Deed shall be referred to as
the "PF Export Receivables Master Trust" (the "Trust") or such other name as the
Trustee, with the consent of Petrobras Finance, may determine, subject to the
satisfaction of all notice and filing requirements of applicable law.

<PAGE>

         (b) The Trustee declares that it shall hold: (i) the Initial Settled
Sum; (ii) all estate, right, title and interest in, to and under the Purchased
Receivables to be Generated; (iii) all estate, right, title and interest in, to
and under the Trustee's rights under any Transaction Documents to which the
Trustee is a party or of which it is a third-party beneficiary; (iv) all estate,
right, title and interest in, to and under the Trust Accounts, Collections from
the Purchased Receivables deposited therein and the Eligible Investments held
therein; and (v) all estate, right, title and interest in, to and under the
Financial Guaranty Insurance Policies, provided that any such Policy shall be
available only in respect of the Series to which such Policy relates, and all
proceeds of the foregoing and all property at any time representing the same
(together, the "Trust Property") upon the trusts set out in this Trust Deed on
and in accordance with the terms and provisions and subject to the powers of
this Trust Deed.

         (c) The Initial Settled Sum and any Trust Property remaining after the
termination of the Trust in accordance with Section 8.01 are collectively
referred to herein as the Charitable Property ("Charitable Property"). The
Charitable Property shall be held in trust to be applied by the Trustee for such
charitable purposes as the Trustee shall in its sole discretion determine.

         (d) The Trustee may in its discretion either allow the Charitable
Property or any part thereof consisting of cash to remain uninvested and any
part being invested to remain in its original state of investment for so long as
the Trustee thinks fit, or at any time at the discretion of the Trustee, the
Trustee may sell any such investment and invest the proceeds or any cash in its
hands in or upon any investment authorized by this Trust Deed, and the Trustee
shall have the power in its absolute discretion to vary such investments.

         (e) Before the Termination Date, the Trustee (i) may from time to time
pay or apply the whole or such part or parts of the income attributable to the
Initial Settled Sum to or for the benefit of any Qualified Charity as the
Trustee shall in its absolute discretion select, in such proportions or manner
as the Trustee shall from time to time think fit or (ii) shall accumulate the
income attributable to the Initial Settled Sum (or so much thereof as shall not
be paid or applied as aforesaid) as an accretion to the capital of the
Charitable Property.

         (f) On and from the Termination Date, the Trustee shall hold the
Charitable Property as to capital and income upon trust to distribute the same
to one or more Qualified Charities (and, if more than one, in such shares as the
Trustee shall in its absolute discretion determine).

         (g) The Trustee declares that it shall hold all estate, right, title
and interest in and to the Trust Property, other than the Charitable Property,
upon trust for the use and benefit of the Senior Certificate Holders, the Junior
Certificate Holders and the Enhancers in accordance with the terms and
provisions of this Trust Deed.

         (h) The purposes of the Trust are limited to: the acquisition and
holding of the Trust Property; the entry by the Trustee into the Receivables
Purchase Agreement, the Servicing Agreement, the Notice and Consents, the Trust
Administration Agreement, the Insurance and Reimbursement Agreements, the
Indemnification Agreements, the Depositary Agreement and certain other related
agreements; the exercise of all rights and powers incidental to the ownership of

and the acquisition and holding of the Charitable Property in accordance with
the terms of this Trust Deed.

     (i)  Each Certificate Holder or other beneficiary and any Person claiming
through or under such Certificate Holder (including any Person on whose behalf
the Certificate Holder or other beneficiary holds Trust Certificates) shall have
both the benefit and the burden of the terms and conditions of this Trust Deed
as if each Certificate Holder or other beneficiary and those other Persons had
been a party to and had executed this Trust Deed, and as if each Certificate
Holder or other beneficiary and those other Persons had covenanted to observe
and be bound by all the provisions of this Trust Deed and had thereby authorized
the Trustee to do all acts and things that this Trust Deed may or shall require
the Trustee to do, or that the Trustee may do in accordance with its provisions.

                   NOW THEREFORE, THIS TRUST DEED WITNESSETH:

                                   ARTICLE I

             DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

     1.01 Definitions; Interpretations. For all purposes of this Trust Deed and
any Supplemental Trust Deed executed pursuant to the terms hereof, except as
otherwise expressly provided or unless the context otherwise requires, defined
terms used in this Trust Deed or in any Supplemental Trust Deed executed
pursuant to the terms hereof shall have the respective meanings assigned to them
in Annex A hereto, and the principles of construction shall be as set forth in
Annex A hereto. Terms used but not defined herein shall have, if defined in the
Receivables Purchase Agreement (whether by cross-reference or otherwise), the
respective meanings specified therein.

     1.02 Compliance Certificates. Upon any application or request by the
Trustee to any Agent to take action under any provision of this Trust Deed, the
Trustee shall furnish to such Agent an Authorized Officer's certificate stating
that all conditions precedent, if any, provided for in this Trust Deed relating
to the proposed action have been complied with, except that in the case of any
particular application or request as to which the furnishing of specific
certificates is specifically required by any provision of this Trust Deed
relating to such particular application or request, no additional certificate
need be furnished.

     1.03 Form of Documents Delivered to Trustee.

     (a)  In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

     (b)  Any certificate or opinion of an Authorized Officer of the Trustee may
be based, insofar as it relates to legal matters, upon a certificate or opinion
of, or representations by,

                                      -3-

<PAGE>

counsel, unless such Authorized Officer knows, or in the exercise of reasonable
care should know, that the certificate or opinion or representations with
respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion or any opinion of counsel may be
based, insofar as it relates to factual matters, upon a certificate or opinion
of, or representations by, an Authorized Officer of the Trustee stating that the
information with respect to such factual matters is in the possession of the
Trustee, unless such Authorized Officer or counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous. Any opinion of counsel may be based
on the written opinion of other counsel, in which event such opinion of counsel
shall be accompanied by a copy of such other counsel's opinion and shall include
a statement to the effect that such counsel believes that it and the Trustee may
reasonably rely upon the opinion of such other counsel.

     (c)  Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments at any one time under this Trust Deed, they may, but need not, be
consolidated and form one instrument.

     (d)  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Trust Deed (including one furnished
pursuant to specific requirements of this Trust Deed relating to a particular
application or request) shall include:

          (i)   a statement that each individual signing such certificate or
     opinion has read such condition or covenant and the definitions relating
     thereto;

          (ii)  a brief statement as to the nature and scope of the examination
     or investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (iii) a statement that, in the opinion of each such individual, he has
     made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (iv)  a statement as to whether, in the opinion of each such
     individual, such condition or covenant has been complied with.

     1.04 Actions of Controlling Parties or Certificate Holders.

     (a)  Subject to Section 2.08, any request, demand, authorization, direction
notice, consent, waiver or other action provided by this Trust Deed to be given
or taken by Controlling Parties or Certificate Holders, as the case may be, may
be embodied in and evidenced by one or more instruments of similar tenor signed
by such Controlling Parties or Certificate Holders, as the case may be, in
person or by one or more agents or proxies duly appointed in writing by such
Controlling Parties or Certificate Holders. Except as herein otherwise expressly
provided, such action shall become effective when such instruments are delivered
to the Trustee. Proof of execution of any such instrument or of a writing
appointing any such agent or proxy shall be sufficient for any purpose of this
Trust Deed and conclusive in favor of the Trustee if made in the manner provided
in this Section 1.04 and in Article XII. Such instruments (and the action

                                      -4-

<PAGE>

embodied therein and evidenced thereby) are herein sometimes referred to as the
"Action" of the Controlling Parties or Certificate Holders, as the case may be.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of a notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Whenever
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his 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 Trustee deems sufficient.

     (c)  The ownership, principal amount and serial numbers of the Trust
Certificates held by any Person, and the date of the commencement and the date
of the termination of holding the same, shall be proved by registry in the
Register, as set forth in Section 2.04(a) hereto.

     (d)  Any request, demand, authorization, direction, notice, consent, waiver
or other Action of any Controlling Party or Certificate Holder, as the case may
be, shall bind every future Certificate Holder of the same Trust Certificate of
such Series and the Certificate Holder of every Trust Certificate of such Series
issued in exchange therefor or in lieu thereof in respect of anything done,
omitted or suffered to be done by the Trustee in reliance thereon, whether or
not notation of such Action is made upon such Senior Trust Certificate.

     1.05 Notices. Any request, demand, authorization, direction, notice,
consent, or waiver of Certificate Holders (and Action of Certificate Holders) or
other document provided or permitted by this Trust Deed to be made upon, given
or furnished to, or filed with, any party to any Transaction Document shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
accordance with the provisions of Section 1.06.

     1.06 Notice to Certificate Holders; Waiver; Notice to Luxembourg Stock
Exchange.

     (a)  Except as otherwise expressly provided in or pursuant to this Trust
Deed, where this Trust Deed provides for notice, approval, consent, request or
other communication, such approval, consent, request or other communication
shall be in writing and shall be hand-delivered, mailed or faxed to the
recipient thereof at their respective addresses or fax numbers specified in this
Section 1.06. Any such notice shall be deemed to have been given on the date of
such delivery, mailing or faxing; provided, however, that in no case shall any
such notice be effective with respect to a particular Certificate Holder earlier
than the date of receipt of such notice by such Certificate Holder.

     (b)  If it shall be impracticable in the opinion of the Trustee to give
notice in the manner described in paragraph (a) above, then such notification in
lieu thereof as shall be made by the Trustee shall constitute sufficient
provision of such notice.

     (c)  Neither the failure to give notice, nor any defect in any notice given
to any particular party or Person shall affect the sufficiency of any notice
with respect to any other party or Person.

                                      -5-

<PAGE>

         (d) Where this Trust Deed provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by any party or Person shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         (e) So long as any Series of Senior Trust Certificates are listed on
the Luxembourg Stock Exchange and the rules of that exchange so require, the
Trustee shall provide to the Luxembourg Paying Agent, which shall provide to the
Company Announcements Office of the Luxembourg Stock Exchange, copies of all
notices provided to the Senior Certificate Holders. In addition, so long as the
Senior Trust Certificates are listed on the Luxembourg Stock Exchange, any
notice given to Senior Certificate Holders shall be published by the Trustee or
the Luxembourg Paying Agent in the Luxemburger Wort or in another daily
newspaper of general circulation in Luxembourg (or, if not practical in
Luxembourg, elsewhere in Europe).

         (f) For so long as Senior Trust Certificates of any Series are rated by
any Rating Agency, the Trustee shall provide to each Rating Agency then
providing a rating of such Series of Trust Certificates copies of all notices it
receives pursuant to the Transaction Documents as well as all notices it
provides to the Senior Certificate Holders and the Enhancers of the Series
covered by such rating (including any notices given to the Enhancers under
Section 4.2 of the Insurance and Reimbursement Agreements) at the address
notified in writing by such Rating Agency to the parties listed in this Section
1.06.

         (g) For so long as any Series of Senior Trust Certificates is
guaranteed by a Financial Guaranty Insurance Policy issued by an Enhancer, the
Trustee shall provide to such Enhancer copies of all notices it receives
pursuant to the Transaction Documents as well as all notices it provides to the
Senior Certificate Holders of such Series at the address notified in writing by
such Enhancer to the parties listed in this Section 1.06.

         (h) Until otherwise so notified by the respective parties, all notices,
approvals, consents, requests and other communications shall be addressed to the
following addressees at their respective addresses set forth below:

     (a)  This Trust Deed and the Trust Certificates issued hereunder shall
be governed by and construed in accordance with the law of the Cayman Islands.

     (b)  Each party hereto hereby submits to the non-exclusive jurisdiction of
the federal and state courts of the State of New York, located in The City of
New York. Each party hereby irrevocably waives, to the fullest extent permitted
by law, any objection that it may now or hereafter have to the laying of venue
of any action or proceeding in the federal and state courts of the State of New
York, located in The City of New York, and any claim that any such action or
proceeding brought in any such court has been brought in an inconvenient forum.

     (c)  Each party hereby irrevocably waives, to the fullest extent permitted
by applicable law, any and all right to trial by jury in any legal proceeding
arising out of or relating to this Trust Deed, the Trust Certificates or the
transactions contemplated hereby or thereby.

     (d)  A final judgment in any such legal action or proceeding arising out of
or relating to this Trust Deed, the Trust Certificates or the transactions
contemplated hereby or thereby shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

     (e)  To the extent that any party may in any jurisdiction claim for itself
or its assets immunity, including sovereign immunity (to the extent that any
such immunity may now or hereafter exist) from suit, execution, attachment
(whether in aid of execution, before judgment or otherwise) or other legal
process (whether through service or notice or otherwise), and to the

                                      -9-

<PAGE>

extent that in any such jurisdiction there may be attributable to such party or
its assets such immunity (whether or not claimed), each party irrevocably agrees
not to claim, and irrevocably waives, such immunity to the full extent permitted
by the laws of such jurisdiction.

     (f)  Nothing contained in this Trust Deed shall preclude the Trustee or any
Certificate Holder from instituting legal proceedings in the courts of any other
jurisdiction having or claiming jurisdiction in respect of this Trust Deed.
Nothing in this Trust Deed shall affect the right to serve process in any other
manner permitted by law or shall limit the right of any party hereto to bring
proceedings against any other party hereto in the courts of any other
jurisdiction.

     1.12 Counterparts; Effectiveness. This Trust Deed and any amendments,
waivers, consents or supplements hereto may be executed in any number of
counterparts, and by different parties hereto in separate counterparts, and each
of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument.
This Trust Deed shall become effective upon the execution and delivery of a
counterpart hereof by each of the parties hereto.

     1.13 Calculations. Calculations required to be made herein on or as of a
specified day shall, unless the context requires otherwise, be made on or as of
the close of business on such day or, if such day is not a Business Day, on or
as of the close of business on the last Business Day prior to such day.

     1.14 Availability of Certain Documents. Executed copies of the Transaction
Documents and the information and reports required to be provided by the Trustee
in accordance with Section 7.01(e) shall be available to Certificate Holders and
Enhancers for inspection during usual business hours at the Specified Offices of
the Trustee and for so long as the Senior Trust Certificates are listed on the
Luxembourg Stock Exchange, at the Specified Office of the Luxembourg Paying
Agent.

     1.15 No Recourse.

     (a)  A director, Authorized Officer, employee, agent, manager, interest
holder or stockholder, as such, of the Trustee, shall not have any liability for
any obligation of the Trustee under the Trust Certificates or the Trust Deed or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Certificate Holder, by accepting a Trust Certificate, waives and
releases all such liability.

     (b)  The obligations of the Trustee under the Trust Deed and the Trust
Certificates shall be non-recourse to the assets of the Trustee and payable only
out of the Trust Property. The Trustee has, and each Certificate Holder by
accepting a Trust Certificate shall be deemed to have, agreed in the Trust Deed
that neither the Trustee in its individual capacity nor its assets (other than
the Trust Property) shall be liable for any of the obligations of the Trustee
under the Trust Deed or the Trust Certificates, except as expressly provided
herein.

                             THE TRUST CERTIFICATES

          2.01 Form and Denomination.


          (a) The Senior Trust Certificates shall represent senior
unsubordinated undivided beneficial interests in the Trust Property other than
the Charitable Property and shall rank in right of payment and otherwise at
least pari passu, without any preference or priority among themselves, with all
existing and future unsubordinated beneficial interests in the Trust. The Senior
Trust Certificates shall be senior to the Junior Trust Certificates on the terms
set forth in Article XIII. The Senior Trust Certificates shall be issued in
fully registered form without interest coupons and shall be substantially in the
form attached hereto as Exhibit A-1, in the case of fixed rate Senior Trust
Certificates, and Exhibit A-2, in the case of floating rate Senior Trust
Certificates, with such appropriate omissions, variations, substitutions and
insertions as are permitted by this Trust Deed and containing such notations,
legends or endorsements as may be required by law or by any usage in respect
thereof. Senior Trust Certificates may be issued from time to time in one or
more Series by the execution of a Supplemental Trust Deed in accordance with
this Section 2.01, Article IV and Article XI.

          (b) The Junior Trust Certificates shall represent junior, subordinated
undivided beneficial interests in the Trust Property other than the Charitable
Property, ranking junior to the Senior Trust Certificates on the terms and
conditions set forth in Article XIII, and shall rank in right of payment and
otherwise at least pari passu, without any preference or priority among
themselves, with all existing and future junior subordinated beneficial
interests in the Trust. The Junior Trust Certificates shall be issued in
definitive, fully registered certificated form without interest coupons and
shall be substantially in the form attached hereto as Exhibit B-1, in the case
of fixed rate Junior Trust Certificates, and Exhibit B-2, in the case of
floating rate Junior Trust Certificates, with such appropriate omissions,
variations, substitutions and insertions as are permitted by this Trust Deed and
containing such notations, legends or endorsements as may be required by law or
by any usage in respect thereof. Junior Trust Certificates may be issued from
time to time in one or more Series by the execution of a Supplemental Trust Deed
and only in accordance with this Section 2.01, Article IV and Article XI.

          (c) Each Supplemental Trust Deed providing for the issuance of any
Series of Trust Certificates shall state therein the aggregate principal amount
of Trust Certificates being issued thereunder and shall include therein or
attached thereto a form of Trust Certificate of such Series, which form shall
set forth therein the Final Payment Date therefor, the amortization schedule
relating thereto and the interest rate applicable thereto and, if applicable,
the manner in which such interest rate shall be calculated. Such Supplemental
Trust Deed or such form of Trust Certificate shall contain any other term or
provision incidental thereto, or relating to restrictions on transfer of the
Trust Certificates of such Series or the qualifications, if any, of each
Certificate Holder of such Series, provided, however, that no such Supplemental
Trust Deed shall amend, modify or add to the provisions of Article III, IV, V,
VI, VII, VIII, IX, XI, XII, XIII or XIV, as applicable to such Trust
Certificates, or modify any date on which any payment is to be made in respect
of the Trust Certificates, except in each case as expressly provided in such
Articles or in accordance with the provisions of Section 11.02. All Trust
Certificates of one Series must be

                                      -11-

<PAGE>

issued at one time and no Series may be reopened for issuances of additional
Trust Certificates of such Series.

          (d) The Trust Certificates shall be issued in minimum denominations of
U.S.$100,000 and integral multiples of U.S.$1,000 in excess thereof (the
"Authorized Denominations"); provided that, any Trust Certificate issued
pursuant to Section 3.06 may be issued in any amount.

          (e) Senior Trust Certificates offered and sold in reliance on Rule
144A shall be issued initially in the form of one or more permanent global
Senior Trust Certificates substantially in the form of Exhibit A-1, in the case
of fixed rate Senior Trust Certificates, and Exhibit A-2, in the case of
floating rate Senior Trust Certificates, with such applicable legends as are
provided for in Section 2.06(c) (each, a "Restricted Global Certificate") duly
executed by the Trustee. Such Restricted Global Certificates shall be in
registered, book-entry form without interest coupons and shall be registered in
the name of The Depository Trust Company ("DTC"), or its nominee, and deposited
on behalf of the purchasers of such Senior Trust Certificates with the Trustee,
at its Specified Office, as custodian for DTC, for credit to the respective
accounts of the purchasers (or to such other accounts as they may direct) at
DTC. The aggregate principal amount of any Restricted Global Certificate may
from time to time be increased or decreased by adjustments made on the records
of the Trustee or the Paying Agent, as custodian for DTC for such Restricted
Global Certificate, as provided in Section 2.06 hereof, which adjustments shall
be conclusive as to the aggregate principal amount of any such Restricted Global
Certificate.

          (f) Senior Trust Certificates offered and sold outside the United
States in reliance on Regulation S shall be issued initially in the form of one
or more permanent global Senior Trust Certificates substantially in the form of
Exhibit A-1, in the case of fixed rate Senior Trust Certificates, and Exhibit
A-2, in the case of floating rate Senior Trust Certificates, with such
applicable legends as are provided for in Section 2.06(c) (each, an
"Unrestricted Global Certificate") duly executed by the Trustee. Such
Unrestricted Global Certificate shall be in registered, book-entry form without
interest coupons and shall be registered in the name of DTC, or its nominee, and
deposited on behalf of the purchasers of such Senior Trust Certificates with the
Trustee, at its Specified Office, as custodian for DTC, for credit to the
respective accounts of the purchasers (or to such other accounts as they may
direct) at Euroclear and/or Clearstream. The aggregate principal amount of the
Unrestricted Global Certificate may from time to time be increased or decreased
by adjustments made on the records of the Trustee, as custodian for DTC for such
Global Certificates, as provided in Section 2.06 hereof, which adjustments shall
be conclusive as to the aggregate principal amount of such Global Certificates.
The Restricted Global Certificate and the Unrestricted Global Certificate are
collectively referred to herein as the "Global Certificates."

          (g) Senior Trust Certificates offered and sold to institutional
"accredited investors" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act (each, an "IAI") that are not QIBs or in a transaction
not exempt from registration under Rule 144A shall be issued initially in the
form of one or more Senior Trust Certificates in definitive, fully registered
certificated form without interest coupons substantially in the form of Exhibit
A-1, in the case of fixed rate Senior Trust Certificates, and Exhibit A-2, in
the case of floating rate Senior Trust

                                      -12-

<PAGE>

Certificates, with such applicable legends as are provided for in Section
2.06(c) and shall be duly executed by the Trustee as hereinafter provided.

          (h)   Junior Trust Certificates shall be issued substantially in the
form of Exhibit B-1, in the case of fixed rate Junior Trust Certificates, and
Exhibit B-2, in the case of floating rate Junior Trust Certificates, in
definitive, fully registered certificated form without interest coupons and with
such applicable legends as are provided in Section 2.06(c) and shall be duly
executed by the Trustee as hereinafter provided. The Junior Trust Certificates
shall be registered in the name of Petrobras Finance or another wholly-owned
Subsidiary of Petrobras. The Trustee shall refuse to register any transfer of a
Junior Trust Certificate that is made in violation of the foregoing restriction.

          (i)   Trust Certificates that are issued in definitive, fully
registered certificated form without interest coupons are referred to as
"Definitive Trust Certificates". The Definitive Trust Certificates shall be
printed, lithographed or engraved or produced by any combination of these
methods or may be produced in any other manner, all as determined by the
Authorized Officer of the Trustee executing such Trust Certificates, as
evidenced by his execution of such Trust Certificates.

          2.02  Authorized Amount, Interest Rate, Maturity Date and Amortization
of Principal.


          (a)   The aggregate principal amount of Trust Certificates that may be
issued and outstanding at any one time under this Trust Deed shall be unlimited,
subject to compliance with the provisions of Article IV. Each Trust Certificate
shall be dated the date of its execution.

          (b)   Each Trust Certificate shall bear interest at the applicable
Certificate Rate of Interest specified on the reverse of such Trust Certificate,
which may be a fixed rate or floating rate. Interest shall accrue on the
outstanding principal amount of each Trust Certificate from and including the
date of issuance of such Trust Certificate to, but excluding the Final Payment
Date and shall be paid on each Payment Date (or for each Senior Trust
Certificate bearing interest at a floating rate, on the day following the last
day of each Monthly Interest Period (as defined and as set forth in the relevant
Supplemental Trust Deed)) or each Junior Trust Certificate Payment Date, as the
case may be, commencing on the date set forth in the relevant Trust Certificate.
To the extent permitted by applicable law, any payments due and not punctually
paid when due on the Senior Trust Certificates shall bear interest until paid at
the applicable Certificate Rate of Interest plus the Default Interest Rate.

          (c)   The Final Scheduled Principal Payment Date for each Senior Trust
Certificate shall be specified on the reverse of such Senior Trust Certificate.

          (d)   The principal amount of each Senior Trust Certificate shall
amortize in accordance with the amortization schedule appearing on the reverse
of such Senior Trust Certificate. The principal amount of each Junior Trust
Certificate shall be due and payable on the Final Payment Date for such Series
of Junior Trust Certificates as specified on the reverse of such Junior Trust
Certificate.

          (e)   Except as provided in this Section 2.02(e), the Trustee shall
make all payments of amounts due on the Trust Certificates without withholding
or deduction of any present or future

                                      -13-

<PAGE>

taxes, duties, levies, imposts, assessments or other governmental charges
(including penalties, interest and other liabilities related thereto) of any
nature imposed by Brazil, the Cayman Islands, the United States or any
jurisdiction from or through which payment is made in respect of the Trust
Certificates, or any political subdivision of any such jurisdiction
(collectively, "Taxes"). If any such Taxes are so imposed or established, the
Trustee shall pay the Certificate Holders such additional amounts as are
necessary to ensure that they receive the same amount as they would have
received had no such withholding or deduction been imposed (such amounts,
"Additional Amounts"). The Trustee shall not, however, pay any Additional
Amounts in connection with any Tax that is imposed due to any of the following
("Excluded Additional Amounts"):

                  (i)    the Certificate Holder has a connection with the taxing
         jurisdiction other than merely holding the Trust Certificates or
         receiving principal or interest payments on the Trust Certificates
         (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 Certificate Holder fails to comply with any
         certification, identification or other reporting requirements
         concerning its nationality, residence, identity or connection with the
         taxing jurisdiction, if

                         (A) such compliance is required by applicable law,
                  regulation, administrative practice or treaty as a
                  precondition to exemption from all or a part of the Tax,

                         (B) the Certificate Holder is able to comply with such
                  requirements without undue hardship, and

                         (C) at least 30 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 Trustee has notified all Certificate Holders that
                  they shall be required to comply with such requirements;

                  (iv)   the Certificate Holder fails to present (where
         presentation is required) its Trust Certificate within 30 days after
         the Trustee has made available to the Certificate Holder a payment
         under a Trust Certificate, provided that the Trustee shall pay
         Additional Amounts which such Certificate Holder would have been
         entitled to had the Trust Certificate owned by such Certificate Holder
         been presented on any day (including the last day) within such 30 day
         period; or

                  (v)    any estate, inheritance, gift, value added, use or
         sales Taxes or any similar Taxes.

         (f)      The Trustee shall pay any stamp, administrative, excise
or property Taxes arising in a taxing jurisdiction in connection with the Trust
Certificates and shall indemnify the Certificate Holders for any such stamp,
administrative, excise or property Taxes paid by Certificate Holders.

or of the Trust Administrator shall sign Trust Certificates by manual signature.
The seal of the Trustee shall be reproduced on Trust Certificates and may be in
facsimile form. A Trust Certificate shall not be valid until manually signed by
an Authorized Officer of the Trustee or of the Trust Administrator. The

     2.04 Registrar, Transfer Agent and Paying Agent.

     (a)  The Trustee shall cause to be maintained an office or agency in The
City of New York where Trust Certificates may be presented for registration of
transfer or for exchange. The Trustee shall cause to be maintained an office or
agency where Trust Certificates may be presented and surrendered for payment.
The Registrar shall keep a register ("Register") of Trust Certificates and of
their transfer and exchange. The Trustee may, at its discretion, appoint one or
more agents (each, a "Paying Agent" and, collectively, the "Paying Agents") for
the payment of any and all amounts due and payable by the Trustee from time to
time in respect of the Trust Certificates, and the Trustee may, at its
discretion, appoint one or more agents (each, a "Transfer Agent" and,
collectively, the "Transfer Agents") for the transfer and exchange of Trust
Certificates, at such place or places as the Trustee may determine, provided,
however, that there shall at all times be a Paying Agent, Transfer Agent and
Registrar in the Borough of Manhattan, The City of New York. So long as the
Senior Trust Certificates are listed on the Luxembourg Stock Exchange and the
rules of the Luxembourg Stock Exchange so require, there shall be maintained a
Paying Agent and a Transfer Agent in Luxembourg (the "Luxembourg Paying Agent").

     (b)  The Trustee hereby appoints Citibank as Paying Agent, Registrar and
Transfer Agent, and Citibank accepts such appointment hereunder. The Trustee is
separately appointing Kredietbank S.A. Luxembourgeoise as Luxembourg Paying
Agent and Luxembourg Listing Agent.

     (c)  The Trustee shall have the right to vary or terminate the appointment
of the Registrar or any Paying Agent or Transfer Agent at any time with or
without cause upon giving 30 days' written notice to the Registrar, such Paying
Agent or Transfer Agent, as the case may be.

     (d)  The Trustee shall promptly notify the Certificate Holders and the
Enhancers in writing of the name and address of each Paying Agent, Registrar or
Transfer Agent appointed by it and shall notify the Certificate Holders and the
Enhancers in writing of the resignation or termination of any Paying Agent,
Registrar or Transfer Agent.

     (e)  The Trustee shall enter into an appropriate agency agreement with any
Agent not a party to this Trust Deed. The agreement shall implement the
provisions of this Trust Deed that relate to such Agent.

     2.05 Book-Entry Provisions for Global Certificates.

the legends set forth in

                                      -15-

<PAGE>

Section 2.06(c). Members of, or participants in, DTC ("Participants") or their
participants ("Indirect Participants") shall have no rights under this Trust
Deed with respect to any Global Certificates held on their behalf by DTC, or the
Trustee as its custodian, and DTC may be treated by the Registrar and any agent
of the Registrar as the absolute owner of such Global Certificates for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Registrar or any agent of the Registrar from giving effect to any written
certification, proxy or other authorization furnished by DTC or shall impair, as
between DTC and its Participants, the operation of customary practices governing
the exercise of the rights of a holder of any Global Certificates. Upon the
issuance of any Global Certificates, the Registrar or its duly appointed agent
shall record DTC as the registered holder of such Global Certificates.

     (b)  Transfers of any Global Certificate shall be limited to transfers of
such Global Certificate in whole, but not in part, to DTC or any nominee or
successor thereof. Beneficial interests in the Global Certificates may be
transferred in accordance with the applicable procedures of DTC and the
provisions of Section 2.06.

     (c)  Any beneficial interest in one of the Global Certificates that is
transferred to a Person who takes delivery in the form of an interest in another
Global Certificate will, upon such transfer, cease to be an interest in such
Global Certificates and become an interest in the other Global Certificate and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Certificate for as long as it retains such an interest.

     (d)  The beneficial interests represented by any Global Certificates shall
be issued as Definitive Trust Certificates to beneficial owners of such Global
Certificates if:

          (i)  DTC notifies the Trustee that it is unwilling or unable to
     continue as depositary for such Global Certificates, or DTC ceases to be a
     "Clearing Agency" registered under the Exchange Act, and a successor
     depositary is not appointed by the Trustee within 90 day of such notice; or

          (ii) a Specified Event has occurred and is continuing and any holder
     of a beneficial interest in Senior Trust Certificates shall advise the
     Trustee in writing through DTC that it wishes to hold its interests in the
     Senior Trust Certificates in the form of Definitive Trust Certificates.

     (e)  In connection with the transfer of a beneficial interest in a
Restricted Global Certificate or Unrestricted Global Certificate to the
beneficial owners thereof pursuant to Section 2.05(d), the principal amount of
such Restricted Global Certificate or Unrestricted Global Certificate, as the
case may be, shall be decreased by the amount of such beneficial interest or, if
the entire beneficial interest in such Global Certificate shall be so exchanged,
such Global Certificate shall be deemed to be surrendered to the Trustee for
cancellation, and the Trustee shall execute and deliver to each beneficial owner
identified by the registered holder thereof in exchange for its beneficial
interest in such Restricted Global Certificate or Unrestricted Global
Certificate, as the case may be, an equal aggregate principal amount of
Definitive Trust Certificates of authorized denominations.

                                      -16-

<PAGE>

     Upon the issuance of Definitive Trust Certificates, the Trustee shall
recognize the Person in whose name the Definitive Trust Certificates are
registered in the Register as a Certificate Holder hereunder. The Trustee shall
not be responsible for locating a successor clearing agency.

     (f)  Any Definitive Trust Certificate delivered in exchange for an interest
in the Restricted Global Certificate pursuant to paragraph (d) of this Section
shall bear the Restricted Legend as set forth in Section 2.06(c).

     (g)  Prior to the expiration of the Distribution Compliance Period, any
Definitive Trust Certificate delivered in exchange for an interest in an
Unrestricted Global Certificate pursuant to paragraph (d) of this Section shall
bear the Restricted Legend, which may be removed after the expiration of the
Distribution Compliance Period upon receipt of a certification of the Holder
thereof, reasonably satisfactory to the Trustee, to the effect that it is not a
"U.S. Person" (as that term is defined in Regulation S) or located in the United
States.

     (h)  The registered holder of any Restricted Global Certificate or
Unrestricted Global Certificate may grant proxies and otherwise authorize any
Person, including Participants and Persons that may hold interests through
Participants, to take any action which a Senior Certificate Holder is entitled
to take under this Trust Deed or the Senior Trust Certificates.

     2.06 Transfer and Exchange. Transfers and exchanges of Senior Trust
Certificates shall be governed by this Section 2.06 and by Section 2.05.
Transfers and exchanges of Junior Trust Certificates shall be governed by
Section 2.01(h) and by the provisions of clause (c)(ii) of this Section 2.06.

          (a) Transfer and Exchange of Beneficial Interests in the Global
     Certificates. The transfer and exchange of beneficial interests in the
     Global Certificates shall be effected through the DTC in accordance with
     the provisions of this Trust Deed and the applicable procedures of DTC.
     Beneficial interests in the Global Certificates shall be subject to the
     restrictions on transfer set forth herein to the extent required by the
     Securities Act. Transfers of beneficial interests in the Global
     Certificates also shall require compliance with either subparagraph (i) or
     (ii) below, as applicable, as well as one or more of the other following
     subparagraphs, as applicable:

          Prior to 40 days after the later of the commencement of each offering
     of any Series of Senior Trust Certificates and the closing date of such
     offering, the transfer and exchange of beneficial interests in the
     Unrestricted Global Certificates may not be made to a U.S. person or a
     person located in the United States or for the account or benefit of any
     such person and shall be effected through Euroclear or Clearstream in
     accordance with the provisions of this Trust Deed and the applicable rules
     and procedures of DTC. Beginning 40 days after the later of the
     commencement of the offering of the Senior Trust Certificates and the
     Closing Date (but not earlier), Unrestricted Global Certificate Holders may
     hold their interests through organizations other than Clearstream or
     Euroclear that are participants in the DTC system.

               (i)  Transfer of beneficial interests in the same Global
          Certificates. Beneficial interests in any Global Certificates may be
          transferred to Persons who

                                      -17-

<PAGE>

               take delivery thereof in the form of a beneficial interest in the
               same Global Certificates, provided (in the case of transfers of
               beneficial interests in Restricted Global Certificates) that such
               transfer is in accordance with the transfer restrictions set
               forth in the Restricted Legend. No written orders or instructions
               shall be required to be delivered to the Registrar to effect the
               transfers described in this Section 2.06(a)(i).

                    (ii)   All other Transfers and Exchanges of Beneficial
               Interests in Global Certificates. In connection with all
               transfers and exchanges of beneficial interests in Global
               Certificates that are not subject to Section 2.06(a)(i) above,
               the transferor of such beneficial interest must deliver to the
               Registrar (A) a written order from a Participant or an indirect
               Participant given to DTC in accordance with the applicable
               procedures of DTC directing DTC to credit or cause to be credited
               a beneficial interest in another Global Certificate in an amount
               equal to the beneficial interest to be transferred or exchanged
               and (B) instructions given in accordance with the applicable
               procedures of DTC containing information regarding the
               Participant account to be credited with such increase and shall
               comply with any further applicable provisions of this Section
               2.06. Upon satisfaction of all of the requirements for transfer
               or exchange of beneficial interests in Global Certificates
               contained in this Trust Deed and the Senior Trust Certificates or
               otherwise applicable under the Securities Act, the Trustee shall
               adjust or cause the adjustment of the principal amount of the
               relevant Global Certificates(s) pursuant to Section 2.06(d).

                    (iii)  Transfer of Beneficial Interests between Global
               Certificates. A beneficial interest in any Global Certificate of
               a Series may be transferred to a Person who takes delivery
               thereof in the form of a beneficial interest in another Global
               Certificate of that Series if the transfer complies with the
               requirements of Section 2.06(a)(ii) above and the additional
               requirements set forth in clauses (A) and (B) below (as
               applicable):

                           (A) Transfers by an owner of a beneficial interest in
                    an Unrestricted Global Certificate to a transferee who takes
                    delivery of such interest through a beneficial interest in a
                    Restricted Global Certificate shall be made only upon
                    receipt by the Registrar of a written certification from the
                    transferor of the beneficial interest in the form provided
                    in Exhibit C to the effect that the transfer is being made
                    to a Person who the transferor reasonably believes is a QIB
                    in a transaction meeting the requirements of Rule 144A and
                    in accordance with any applicable securities laws of any
                    state of the United States or any other jurisdiction.

                           (B) Transfers by an owner of a beneficial interest in
                    a Restricted Global Certificate to a transferee who takes
                    delivery of such interest through an Unrestricted Global
                    Certificate will be made only upon receipt by the Registrar
                    of a written certification from the transferor in the form
                    provided as Exhibit C to the effect that such transfer is
                    being made in accordance with Regulation S.

                    (iv) Transfers and Exchange of Beneficial Interests for
               Definitive Trust Certificates. A beneficial interest in any
               Global Certificate may be transferred to an IAI who takes
               delivery thereof in the form of a Definitive Trust Certificate if
               the proposed transferee has delivered to the Registrar a letter
               substantially in the form of Exhibit D hereto and the aggregate
               principal amount being transferred is at least U.S.$100,000. An
               IAI that is not a QIB but is a U.S. Person shall only hold
               Definitive Trust Certificates.

                    In connection with any transfer or exchange of a portion of
               the beneficial interest in any Global Certificate to beneficial
               owners for Definitive Certificates, the Registrar shall reflect
               on its books and records the date and a decrease in the principal
               amount of the Global Certificate in an amount equal to the
               principal amount of the beneficial interest in the Global
               Certificate to be transferred, and the Trust shall execute,
               authenticate and deliver, one or more Definitive Certificates of
               like tenor and principal amount of authorized denominations.

                    (v)  Transfers and Exchanges of Definitive Trust
               Certificates for Global Certificates. Definitive Trust
               Certificates may be exchanged for or transferred to a Person who
               takes delivery in the form of a beneficial interest in a Global
               Certificate upon receipt by the Trustee of written certification
               from the transferor in the form of Exhibit C to the effect that
               either (A) the transfer is being made to a Person who the
               transferor reasonably believes is a QIB in a transaction meeting
               the requirements of Rule 144A (in the case of a beneficial
               interest in a Restricted Global Certificate) or (B) such transfer
               is being made in accordance with Regulation S (in the case of a
               beneficial interest in an Unrestricted Global Certificate) and,
               in each case, in accordance with any applicable securities laws
               of any state of the United States or any other jurisdiction.

                    Upon receipt by the Trustee of instructions given in
               accordance with DTC's and the Registrar's procedures therefor,
               the Registrar shall reflect on its books and records the date and
               an increase in the principal amount of the Unrestricted Global
               Certificate or Restricted Global Certificate, as applicable, in
               an amount equal to the principal amount of the Definitive Trust
               Certificate to be transferred, and the Trustee shall cancel the
               Definitive Trust Certificate so transferred.

               (b)  Transfer and Exchange of Definitive Trust Certificates for
          Definitive Trust Certificates.

                    (i)  Upon request by a holder of Definitive Trust
               Certificates and such holder's compliance with the provisions of
               this Section 2.06(b), the Registrar shall register the transfer
               or exchange of Definitive Trust Certificates. Prior to such
               registration of transfer or exchange, the requesting Holder shall
               present or surrender to the Registrar the Definitive Trust
               Certificates duly endorsed or accompanied by a written
               instruction of transfer in form satisfactory to the Registrar
               duly executed by such holder or by his attorney, duly authorized
               in writing. In addition, the requesting holder shall provide any
               additional

                                      -19-

               required pursuant to the following provisions of this Section
               2.06(b).

                    (ii) Any Definitive Trust Certificate may be transferred to
               and registered in the name of Persons who take delivery thereof
               in the form of a Definitive Trust Certificate if the Registrar
               receives a certificate in the form of Exhibit C hereto, including
               the certifications, certificates and opinion of counsel required
               therein, if applicable.

                    REGULATION S UNDER THE SECURITIES ACT. THE TRUST DEED
                    CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
                    REGISTER ANY TRANSFER OF THE CERTIFICATE IN VIOLATION OF THE
                    FOREGOING RESTRICTIONS.

                         Such legend shall be removed from any Senior Trust
                    Certificate only upon receipt by the Trustee of an Officer's
                    Certificate and Opinion of Counsel reasonably acceptable to
                    the Trustee to the effect that such Senior Trust Certificate
                    does not constitute a "restricted security" as defined in
                    Rule 144 under the Securities Act and, in accordance with
                    said Rule 144, can be resold without restriction.

                         (B) Each Global Certificate shall bear the following
                    legend on the face thereof:

                    UNLESS THIS SECURITY IS PRESENTED BY AN AUTHORIZED

                    REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
                    SECURITY ISSUED IN EXCHANGE FOR THIS SECURITY IS REGISTERED
                    IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
                    REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY
                    PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY
                    AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
                    TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE
                    BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED
                    OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

                    TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO
                    TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR
                    TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND
                    TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE
                    LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
                    RESTRICTIONS SET FORTH IN SECTIONS 2.05, 2.06 AND 2.07 OF
                    THE TRUST DEED REFERRED TO HEREIN.

                    (C) Each Senior Trust Certificate shall also bear the
               following legend on the face thereof:

               BY ITS ACQUISITION HEREOF, THE HOLDER REPRESENTS THAT (I) NO
               ASSETS OF A PERSON WHO IS OR AT ANY TIME WHEN SENIOR TRUST
               CERTIFICATES ARE HELD WILL BE AN ERISA PLAN OR AN INDIVIDUAL
               RETIREMENT ACCOUNT, OR ANOTHER EMPLOYEE BENEFIT PLAN SUBJECT TO
               ANY FEDERAL STATE, LOCAL OR FOREIGN LAW SUBSTANTIALLY SIMILAR TO
               SECTION 406 OF ERISA OR SECTION 4975 OF THE INTERNAL REVENUE
               CODE, HAVE BEEN USED TO ACQUIRE THE SENIOR TRUST CERTIFICATE OR
               AN INTEREST THEREIN OR (II) THE PURCHASE AND HOLDING OF THE
               SENIOR TRUST CERTIFICATE OR AN INTEREST THEREIN ARE AND WILL BE
               EXEMPT FROM THE PROHIBITED TRANSACTION RESTRICTIONS OF ERISA AND
               THE INTERNAL REVENUE CODE BY VIRTUE OF PTCE 90-1, PTCE 91-38,
               PTCE 84-14, PTCE 95-60 OR PTCE 96-23 (OR, IN THE CASE OF SUCH
               ANOTHER EMPLOYEE BENEFIT PLAN, DO NOT AND WILL NOT VIOLATE ANY
               SUBSTANTIALLY SIMILAR LAW).

                    (D) In the case of Definitive Trust Certificates issued in
               exchange for interests in the Restricted Global Certificate, such
               Definitive Trust Certificates shall bear the legend set forth on
               the Restricted Global Certificate.

               (ii) Restricted Legend for Junior Trust Certificates. Each Junior
          Trust Certificate (and all Junior Trust Certificates issued in
          exchange therefor or substitution thereof) shall bear a legend in
          substantially the following form:

          "THIS SECURITY MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE
          TRANSFERRED IN WHOLE OR IN PART EXCEPT TO PETROBRAS FINANCE LTD. OR TO
          ANOTHER WHOLLY-OWNED SUBSIDIARY OF PETROLEO BRASILEIRO S.A. -
          PETROBRAS. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST
          HEREIN, THE HOLDER AGREES THAT IT SHALL DELIVER TO EACH PERSON TO WHOM
          THIS JUNIOR TRUST CERTIFICATE OR AN INTEREST HEREIN IS TRANSFERRED A
          NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND AND THAT ANY
          PURPORTED TRANSFER IN VIOLATION OF THE FOREGOING RESTRICTIONS SHALL BE
          VOID AND WITHOUT EFFECT. THE TRUST DEED CONTAINS A PROVISION REQUIRING
          THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS SECURITY IN
          VIOLATION OF THE FOREGOING RESTRICTIONS."

          (d)  Cancellation and/or Adjustment of Global Certificates. At such
     time as all beneficial interests in a Global Certificate have either been
     exchanged for Definitive Trust Certificates, prepaid, repurchased or
     cancelled, such Global Certificates shall be

                                      -22-

<PAGE>

          returned to the Trustee, who shall cancel it. At any time prior to
          such cancellation, if any beneficial interest in a Global Certificate
          is exchanged for Definitive Trust Certificates, prepaid, repurchased
          or cancelled, the principal amount of Senior Trust Certificates
          represented by such Global Certificate shall be reduced and an
          endorsement shall be made on such Global Certificate, by the Trustee
          or custodian, at the direction of the Trustee to reflect such
          reduction.

               (e)  General Provisions With Respect to Transfer and Exchanges of
          Trust Certificates.

                    (i)   To permit registrations of transfers and exchanges,
               the Trustee shall execute Global Certificates, Definitive Trust
               Certificates and Junior Trust Certificates at the Registrar's
               request.

                    (ii)  No service charge shall be made to a Certificate
               Holder for any registration of transfer or exchange, but the
               Trustee may require payment of a sum sufficient to cover any
               transfer tax or similar governmental charge payable in connection
               therewith (other than any such transfer taxes or similar
               governmental charges payable upon exchange or transfer pursuant
               to Section 2.02(e) hereof).

                    (iii) Upon surrender for registration of transfer of any
               Trust Certificate at the registered office or such other office
               or agency, the Trustee shall execute and deliver, in the name of
               the designated transferee or transferees, one or more new Trust
               Certificates in authorized denominations of a like aggregate
               principal amount. At the option of a Certificate Holder, and
               subject to the provisions of Section 2.06, Trust Certificates may
               be exchanged for other Trust Certificates of authorized
               denominations of a like aggregate principal amount, or may be
               transferred in the amount of any Authorized Denomination, upon
               surrender of the Trust Certificates to be exchanged at any such
               office or agency. The Registrar shall not be required to register
               the transfer or exchange of any Trust Certificate selected for
               prepayment in whole or in part, except the unpaid portion of any
               Trust Certificate being prepaid in part.

                    (iv)  No such transfer shall be effected until, and such
               transferee shall succeed to the rights of a Certificate Holder
               only upon, final acceptance and registration of transfer by the
               Registrar in the Register. Prior to the registration of any
               transfer by a Certificate Holder as provided herein, the Trustee
               shall treat the Person in whose name the Trust Certificate is
               registered as the owner thereof for all purposes and the Trustee
               shall not be affected by notice to the contrary. Whenever any
               Trust Certificates are so surrendered for transfer or exchange,
               the Registrar shall register the transfer or make the exchange as
               requested if the requirements for such transaction are met, and
               the Trustee shall execute and deliver the Trust Certificates that
               the Certificate Holder making the exchange is entitled to
               receive. Every Trust Certificate presented or surrendered for
               registration of transfer or exchange shall be duly endorsed or
               accompanied by a written instrument of transfer in form
               satisfactory to the Trustee and the Registrar

                                      -23-

<PAGE>

               duly executed by the Certificate Holder thereof or its attorney
               duly authorized in writing.

                    (v)    All Global Certificates, Definitive Trust
               Certificates and Junior Trust Certificates issued upon any
               registration of transfer or exchange of Global Certificates,
               Definitive Trust Certificates or Junior Trust Certificates, as
               the case may be, shall be the valid obligations of the Trustee,
               and entitled to the same benefit under this Trust Deed as the
               Global Certificates, Definitive Trust Certificates or Junior
               Trust Certificates, as the case may be, surrendered upon such
               registration of transfer or exchange.

                    (vi)   The Trustee shall not be required to issue, register
               the transfer of, or exchange of Trust Certificates during a
               period beginning at the opening of business 15 days before the
               day of any selection of Trust Certificates for prepayment under
               Section 3.01 and ending at the close of business on the day of
               selection.

                    (vii)  Prior to due presentment for registration of transfer
               of any Trust Certificate, the Trustee and any Agent may deem and
               treat the Person in whose name any Trust Certificate is
               registered as the absolute owner of such Trust Certificate for
               the purpose of receiving payment of principal, interest and
               Additional Amounts, if any, on such Trust Certificate, and
               neither the Trustee, any Agent nor the Trustee shall be affected
               by notice to the contrary.

                    (viii) The Trustee shall not have any responsibility or
               liability for any aspect of the records relating to, or payments
               made on account of, Senior Trust Certificates by DTC, or for
               maintaining, supervising or reviewing any records of DTC relating
               to such Senior Trust Certificates. The Trustee shall not be
               liable for any delay by the related Certificate Holder or DTC in
               identifying the beneficial owners of the related Senior Trust
               Certificates and the Trustee may conclusively rely on, and shall
               be protected in relying on, instructions from such Certificate
               Holders or of DTC for all purposes (including with respect to the
               registration and delivery, and the respective principal amounts,
               of Senior Trust Certificates to be issued).

                    (ix)   The Registrar shall retain copies of all letters,
               notices and other written communications received pursuant to
               this Section. The Trustee shall have the right to inspect and
               make copies of all such letters, notices or other written
               communications at any reasonable time upon the giving of
               reasonable written notice to the Registrar.

          2.07 Replacement of Lost, Mutilated or Stolen Trust Certificates. If
any mutilated Trust Certificate is surrendered to the Trustee, or the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Trust Certificate, the Trustee shall issue a replacement Trust Certificate. If
required by the Trustee, an indemnity bond shall be supplied by the Certificate
Holder that is sufficient in the judgment of the Trustee to protect the Trustee
and any Agent from any loss which any of them may suffer if such Trust
Certificate is replaced. The

                                      -24-

<PAGE>

Trustee may charge such Certificate Holder for its expenses in replacing the
Trust Certificate. Every replacement Trust Certificate issued in accordance with
the provisions hereunder shall represent a beneficial interest in the Trust.

     2.08 Outstanding Trust Certificates.

     (a)  The Trust Certificates "outstanding" at any time shall include all
Trust Certificates issued by the Trustee pursuant to the provisions of this
Trust Deed, except for those cancelled by it, those delivered to it for
cancellation in accordance with Section 2.09 and those described in this Section
2.08 and Section 2.10 as not outstanding.

     (b)  If a Trust Certificate is replaced pursuant to Section 2.07 hereof, it
ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Trust Certificate is held by a bona fide purchaser.

     (c)  If the principal amount of any Trust Certificate is considered paid
under Section 3.04 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

     (d)  If the Paying Agent (other than the Trustee or a Subsidiary or
Affiliate of the Trustee) segregates and holds in trust, in accordance with this
Trust Deed, on a Payment Date or a Junior Trust Certificate Payment Date, as the
case may be, money sufficient to pay all principal, interest, Additional
Amounts, if any, and all other amounts payable on that date with respect to any
Trust Certificates (or the portion thereof to be prepaid or maturing, as the
case may be), then on and after that date such Trust Certificates (or portions
thereof) shall be deemed to be no longer outstanding and shall cease to accrue
interest, and, if applicable, no draw under a Financial Guaranty Insurance
Policy may be made in respect thereof.

     (e)  In determining whether the Controlling Parties represent or hold the
requisite principal amount of Trust Certificates for the purpose of concurring
in any request, demand, authorization, direction, notice, consent, waiver or
other act permitted to be taken or given under this Trust Deed or the other
Transaction Documents, (i) Senior Trust Certificates which are owned by the
Trustee, Petrobras or any of their Affiliates and (ii) all Junior Trust
Certificates, shall be disregarded and shall be deemed not to be outstanding for
any such determination.

     2.09 Cancellation. The Registrar and Paying Agent shall forward to the
Trustee any Trust Certificates surrendered to them for registration of transfer,
exchange or payment. The Trustee shall cancel all Trust Certificates surrendered
for registration of transfer or exchange, payment, replacement or cancellation.
The Trustee shall not issue new Trust Certificates to replace Trust Certificates
that have been prepaid or that have been delivered to the Trustee for
cancellation.

     2.10 Senior Trust Certificates Purchased by Petrobras and its Affiliates.
Petrobras or its Affiliates may at any time purchase any Senior Trust
Certificate in the open market or by tender at any price or by private
agreement. All Senior Trust Certificates so purchased by Petrobras or its
Affiliates may be held for the account of Petrobras or its Affiliates and may be
resold by Petrobras and its Affiliates; provided that, any such Senior Trust
Certificate held for the account of Petrobras or any Affiliate of Petrobras
shall not be deemed to be outstanding for

                                      -25-

<PAGE>

the purposes of Section 2.08 or for the purposes of drawing under a Financial
Guaranty Insurance Policy.

     2.11 References to Interest and Principal. For the avoidance of doubt, any
reference in this Trust Deed, any Supplemental Trust Deed or any Trust
Certificate to the payment of principal and interest in connection with any
Trust Certificate shall be construed to mean payments by means of distributions
out of the Trust Property.

                                  ARTICLE III

                                   PREPAYMENT

     (a)  The Trustee shall prepay, in accordance with the provisions of

pursuant to Section 5.01(a) of the Receivables Purchase Agreement. In such
event, the Trustee shall prepay (i) the Senior Trust Certificates of such Series
in an amount equal to the sum of (A) the outstanding principal amount of the

respect of such Senior Trust Certificates and (ii) all accrued and unpaid
Administrative Expenses, Guaranty Premiums and all other amounts payable by the

     (b)  In the event that any proceeds from the repurchase of such Purchased
Receivables remain after the Optional Prepayment Price is paid pursuant to
paragraph (a) above, such excess proceeds shall be applied to the mandatory
prepayment of the corresponding Series of Junior Trust Certificates on a ratable
basis, on the Junior Trust Certificate Payment Date immediately following the
Prepayment Date.

     3.02 Notice of Prepayment to Certificate Holders.

     (a)  At least 30 days but not more than 60 days before the Payment Date on
which any prepayment of Senior Trust Certificates is to be made pursuant to the
terms hereof (such Payment Date, a "Prepayment Date"), the Trustee shall give a
notice of prepayment in the manner provided in Section 1.06 to each Senior
Certificate Holder whose Senior Trust Certificates are to be prepaid and to the
relevant Enhancers. All notices of prepayment shall identify the Senior Trust

     stating the amount of any and all principal, interest, Additional Amounts,
     if any, amounts payable under the Insurance Documents, breakage costs,
     Administrative Expenses and

     surrendered to the Paying Agent to collect the prepayment price;

          (v)   that, unless the Trustee defaults in making such prepayment,
     interest on such Senior Trust Certificates or such portions of Senior Trust
     Certificates ceases to accrue on and after the Prepayment Date;

          (vi)  the paragraph of the Senior Trust Certificates or Section of
     this Trust Deed pursuant to which the Senior Trust Certificates called for
     prepayment are being prepaid; and

          (vii) that no representation is made as to the correctness or accuracy
     of the CUSIP number, if any, listed in such notice or printed on such
     Senior Trust Certificates.

     (b)  So long as any Series of Senior Trust Certificates is listed on the
Luxembourg Stock Exchange, any notice of prepayment shall be published once by
the Trustee in the Luxemburger Wort or in another daily newspaper of general
circulation in Luxembourg (or, if not practical in Luxembourg, elsewhere in
Europe) at least 30 but not more than 60 days before the Prepayment Date.

     3.03 Effect of Notice of Prepayment. Once the notice of prepayment is given
in accordance with Section 3.02, Senior Trust Certificates called for prepayment
shall become irrevocably due and payable on the Prepayment Date at the

on and after the Prepayment Date interest shall cease to accrue on the relevant
Series of Senior Trust Certificates or, in the case of a mandatory prepayment
pursuant to Section 3.08, the portions of such Senior Trust Certificates, to be
prepaid. If a Senior Trust Certificate is prepaid on or after a Regular Record
Date but on or prior to the related Payment Date, then all amounts in respect of
such prepayment shall be paid to the Person in whose name such Senior Trust
Certificate was registered at the close of business on such Regular Record Date.
If any Senior Trust Certificate called for prepayment shall not be so paid upon
surrender for prepayment because of the failure of the Trustee to comply with
the preceding paragraph, interest shall be paid on the outstanding

                                      -27-

principal, from the Prepayment Date until such principal is paid, and to the
extent lawful, on any interest not paid on such outstanding principal, in each
case at the rates provided in the Senior Trust Certificates.

expense of the Trustee) a new Senior Trust Certificate equal in principal amount
to the remaining unpaid portion of such Senior Trust Certificate surrendered.

     3.07 Tax Prepayment.

     (a)  The Trustee shall, in accordance with the provisions of Sections 3.02,
3.03 and 3.04, prepay all of the Senior Trust Certificates, in whole but not in
part, in the event that Petrobras Finance elects to repurchase the Trustee's

     Fifth, to the payment of principal to the Senior Certificate Holders that
     is scheduled to be paid on such Payment Date; and

     Sixth, to the payment of all Guaranty Premiums and other amounts due and

     (c)  Notwithstanding anything to the contrary herein, the Trustee shall
only make distributions from the Senior Trust Certificate Account on each
Payment Date in accordance with the Payment Determination made on the related
Cut-Off Date, and any amounts that are received into the Senior Trust
Certificate Account after the related Cut-Off Date shall be counted towards the
Payment Determination for the immediately following Payment Date.

     (d)  So long as any Senior Trust Certificates are being held through DTC,
at least one Business Day prior to each Payment Date, the Paying Agent hereby
agrees to provide to DTC a notice with respect to the U.S. dollar amount per

the Reserve Account or an Acceptable Letter of Credit to the Trustee, in either
case, in an amount equal to the Quarterly Senior Payment Amount then scheduled
or otherwise known to be payable by an Authorized Officer of the Trustee on the
next following Payment Date. Thereafter, on each Payment Date, the Trustee shall
ensure, pursuant to clause Third of Section 5.06(a), that the balance in the
Reserve Account (including, if applicable, any funds available under any
Acceptable Letter of Credit then outstanding) equals the Quarterly Senior
Payment Amount then scheduled, or otherwise known to be payable by an

                                      -36-

<PAGE>

Authorized Officer of the Trustee, on the next following Payment Date (such
amount, the "Reserve Account Cap").

     5.10  Withdrawals from Reserve Account.

     (a)   If, on the Cut-Off Date, there is a shortfall in the amounts
available in the Senior Trust Certificate Account to make the distributions
described under clauses Second through Fifth of Section 5.08(b), the Trustee
shall direct the Depositary Bank to promptly withdraw funds from the Reserve
Account or, in the case of an Acceptable Letter of Credit, draw under the
Acceptable Letter of Credit (to the extent available thereunder) in an amount
equal to the amount of such deficiency and deposit such amount in the Senior
Trust Certificate Account at or prior to 12:00 p.m. New York time on such date.
In the event of such use, the Trustee shall be required to replenish the Reserve
Account in accordance with Section 5.06(a).

     (b)   In lieu of funding cash or cash equivalents in the Reserve Account,
an Acceptable Letter of Credit issued with a principal amount equal to the
Reserve Account Cap at the time of issuance, for the account of a party other
than the Trustee and having terms that require that any drawing thereunder be
deposited in the Reserve Account, may be delivered to the Trustee at any time
prior to the occurrence of an Acceleration Event. Unless the Trustee receives
written notice at least 20 Business Days prior to the date of expiration of any
Acceptable Letter of Credit deposited with the Trustee that such Acceptable
Letter of Credit shall be renewed, the Trustee shall draw the full amount
available thereunder and deposit the amount paid pursuant to such drawing in the
Reserve Account. If at any time (a) an Authorized Officer of the Trustee becomes
aware that an issuer of such letter of credit has ceased to be an Acceptable LC
Issuer, or (b) upon the Trustee's receipt of notice from an Acceptable LC Issuer
that a "default" has occurred under the agreement between the account party and
such Acceptable LC Issuer, then, in either case, the Trustee, promptly upon
becoming aware or upon the receipt of such notice, as the case may be, shall
draw the full amount available to be drawn under such Acceptable Letter of
Credit at an office located in the Borough of Manhattan, The City of New York
and shall deposit such amount in the Reserve Account.

     (c)   If as of any Payment Date (after giving effect to the distributions
required to be made on such Payment Date), the balance in the Reserve Account
(including income generated by the investment of such funds in Eligible
Investments) exceeds the Reserve Account Cap, so long as no Acceleration Event
or Accumulation Event has occurred and is continuing, the Trustee shall direct

           (e)  Investment Company Act. The Trustee represents and warrants that
     it is a "bank" as defined in the Investment Company Act and otherwise meets

          Export Contract.

          (c)  Ranking. The Trustee shall (i) not take any action, or (ii) fail
     to take such action which would cause the Senior Trust Certificates, in

written notice of such Event (identifying the event that gave rise to such
Specified Event and stating whether such event also constitutes an Accumulation
Event and/or an Incipient Termination Event) (a "Specified Event Notice") to the
Certificate Holders, each Enhancer, Petrobras Finance and the Servicer (with a
copy to Petrobras). Subject to the following proviso, at any time during the
continuation of a Specified Event, upon the direction of Controlling Parties
representing at least 35% of the aggregate principal amount of the outstanding
Senior Trust Certificates, the Trustee shall, by written notice to Petrobras
Finance and the Enhancers (with a copy to Petrobras and the Servicer) (an
"Acceleration Event Notice"), declare an accelerated amortization of all of the
outstanding Senior Trust Certificates (an "Acceleration Event"), in each case
without further presentment, demand, protest or other requirements of any kind,
all of which shall be expressly waived by the Trustee; provided, that in the
case of any Bankruptcy Event in respect of Petrobras (other than a Bankruptcy
Event solely with respect to a Material Subsidiary of Petrobras), Petrobras
Finance or the Trust, an Acceleration Event shall automatically be deemed to
have occurred. Upon the occurrence of an Acceleration Event, the Trustee shall
direct the Depositary Bank to retain and transfer all amounts held in the
Purchased Receivables Account and the Junior Trust Certificate Subaccount
thereof to the Retention Account in accordance with Section 5.06(e).

     9.02 Application of Proceeds Upon Acceleration Event. Upon the occurrence
of an Acceleration Event, the Trustee shall direct the Depositary Bank to
withdraw all amounts held in the Retention Account and apply such amounts in the
following order of priority, ratably in accordance with the respective amounts
payable at each such level of priority, on the first Business Day of each
Monthly Period thereafter:

     First, to the payment of all unpaid Administrative Expenses due hereunder;

     Second, to the payment of any interest and Additional Amounts, if any,
     originally scheduled to be paid to the Senior Certificate Holders from
     previous Payment Dates but not so paid, or to the Enhancers to the extent
     of any Guaranty Reimbursements in respect of amounts paid under a Financial
     Guaranty Insurance Policy relating to such interest amounts not so paid;

     Third, to the payment of scheduled interest and Additional Amounts, if any,
     to the Senior Certificate Holders that has accrued to such date;

     Fourth, to the payment of any principal originally scheduled to be paid to
     the Senior Certificate Holders from previous Payment Dates but not so paid,
     or to the Enhancers to the extent of any Guaranty Reimbursements in respect
     of amounts paid under a Financial Guaranty Insurance Policy relating to
     such amounts not so paid;

                                      -46-

<PAGE>

     Fifth, to the payment of principal to the Senior Certificate Holders that
     is scheduled to be due on the next following Payment Date or, if such
     prepayment date is a Payment Date, then to the payment of principal due on
     such Payment Date;

     Sixth, with respect to any Enhancer, to the payment of all Guaranty
     Premiums that have accrued to such date and other amounts payable to such
     Enhancer under the relevant Insurance Documents;

     Seventh, to the payment of any remaining principal (to the extent not paid
     pursuant to the Clauses above), accrued and unpaid interest on the
     principal so prepaid, breakage costs, if any, payable in respect of each
     Series of outstanding Senior Trust Certificates to the Senior Certificate
     Holders of such Series and any other amounts payable to the Senior
     Certificate Holders; and

     Eighth, to the payment of interest on, and principal of, the Junior Trust
     Certificates then outstanding.

     9.03 Waiver of Specified Events. Prior to an Acceleration Event,
Controlling Parties representing more than 66 2/3% of the aggregate principal
amount of all outstanding Senior Trust Certificates may vote to waive any
Specified Event hereunder and its consequences, except a default (a) in the
payment of principal of or interest on any of the Senior Trust Certificates or
(b) in respect of a covenant or provision hereof which cannot be modified or
amended without the consent of each Senior Certificate Holder affected. In the
case of any such waiver, the Trustee, the Enhancers and the Certificate Holders
shall be restored to their former positions and rights hereunder, respectively,
and the relevant Specified Event shall cease to exist and be deemed to have been
cured and not to have occurred for every purpose of this Trust Deed; provided
that such waiver shall not extend to any subsequent or other Specified Event or
impair any right consequent thereon. The Trustee shall notify the Servicer, each
Enhancer and each Rating Agency of each such waiver as to which an Authorized
Officer has actual knowledge.

     9.04 Proceedings in Event of Specified Event.

     (a)  In addition to the actions provided in Section 9.02 and Section
9.04(e), upon the occurrence and continuation of any Specified Event the Trustee
shall, at the direction of Controlling Parties representing at least 35% of the
aggregate principal amount of all outstanding Senior Trust Certificates,
institute proceedings to seek or enforce any remedy to protect and enforce any
of its rights or powers hereunder, to the extent permitted by applicable law.
The Trustee shall not be bound to institute any such proceedings or take any
other action, except as otherwise provided in this Section 9.04 unless (i) it
shall have been so directed in writing by such Controlling Parties and (ii) it
shall have been furnished, by the Controlling Parties, or otherwise, indemnity
to its reasonable satisfaction.

     (b)  At any time the Trustee is entitled to institute proceedings to
enforce its rights under this Trust Deed and the Trust Certificates, the
following shall be applicable:

          (i)  the Trustee in its own name, and as trustee of the Trust, shall
     be entitled and empowered to institute any suits, actions or proceedings at
     law, in equity or otherwise, to recover judgment against any Person, for
     the whole amount due and unpaid

                                      -47-

<PAGE>

     from such Person under the applicable agreement, and may prosecute any such
     claims or proceedings to judgment or final decree against the such other
     Person, and collect the moneys adjudged or decreed to be payable in any
     manner provided by law, whether before or after or during the pendency of
     any proceedings for the enforcement of the Trustee's rights or the rights
     of the Enhancers and the Certificate Holders, as their interests may
     appear, under this Trust Deed and the Trust Certificates, and such power of
     the Trustee shall not be affected by the exercise of any other right, power
     or remedy for the enforcement of the provisions of this Trust Deed or the
     Trust Certificates;

          (ii)  the Trustee in its own name, or as trustee of the Trust, as the
     case may be, or in any one or more of such capacities shall be entitled and
     empowered to file such proofs of claim and other papers or documents as may
     be necessary or advisable in order to have the claims of the Trustee, the
     Enhancers and of the Certificate Holders, as their interests may appear
     (whether such claims be based upon the provisions of such Trust
     Certificates or of this Trust Deed) allowed in any receivership,
     insolvency, bankruptcy, moratorium, liquidation, readjustment,
     reorganization or any other judicial or other proceedings, and any
     receiver, assignee, trustee, liquidator, sequestrator (or other similar
     official) in any such judicial or other proceeding is hereby authorized to
     make such payments to the Trustee and, in the event that the Trustee shall
     consent to the making of such payments directly to the Enhancers and/or the
     Certificate Holders, to pay to the Trustee any amount due to it for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel;

          (iii) all rights of action and of asserting claims under this Trust
     Deed or under any of the other Transaction Documents or under any of the
     Trust Certificates enforceable by the Trustee may be enforceable by the
     Trustee to the extent permitted by law without possession of any of such
     Trust Certificates or the production thereof at the trial or other
     proceedings relative thereto; and

          (iv)  in case the Trustee shall have proceeded to enforce any right
     under this Trust Deed or under any of the Transaction Documents by suit,
     foreclosure or otherwise and such proceedings shall have been discontinued
     or abandoned for any reason, or shall have been determined adversely to the
     Trustee, then in every such case the Trustee shall, to the extent permitted
     by law, be restored without further act to its former position and rights
     under this Trust Deed, and all rights, remedies and powers of the Trustee
     shall continue as though no such proceedings had been taken, except to the
     extent determined in litigation adversely to the Trustee.

     (c)  In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Trust Property, the Trustee (irrespective of
whether the principal of the Trust Certificates shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether any
demand for the payment of overdue principal or interest has been made) shall be
entitled and empowered, by intervention in such proceeding or otherwise:

          (i)   to file and prove a claim for the whole amount of principal,
     interest and other amounts owing and unpaid in respect of the Trust
     Certificates and under the

                                      -48-

<PAGE>

     Insurance Documents and to file such other papers or documents as may be
     necessary or advisable in order to have the claims of the Trustee
     (including any claims for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Enhancers and the Certificate Holders, as their interests may appear
     hereunder, allowed in such judicial proceeding; and

          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same; and any
     custodian, receiver, assignee, trustee, liquidator, sequestrator or similar
     official in any such judicial proceeding is hereby authorized by the
     Enhancers and each Certificate Holder to make such payments to the Trustee
     and, in the event that the Trustee shall consent to the making of such
     payments directly to the Enhancers and/or the Certificate Holders, to pay
     the Trustee any amount due it for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsels, and any
     other amounts due the Trustee.

     (d)  Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of the Enhancers or any
Certificate Holder any proposal, plan of reorganization, arrangement, adjustment
or composition or other similar arrangement affecting the Trust Certificates or
the rights of the Enhancers or any Certificate Holder, or to authorize the
Trustee to vote in respect of the claim of any Enhancer or any Certificate
Holder in any such proceeding.

     (e)  In addition to the remedies provided in Sections 9.02 and 9.04(a) with
respect to a Specified Event, upon the occurrence and during the continuation of
a Specified Event or in the event of a Servicer Default, the Trustee shall, at
the direction of Controlling Parties representing more than 50% of the aggregate
principal amount of all outstanding Senior Trust Certificates, remove the
Servicer and appoint a Successor Servicer (as such term is defined in the
Servicing Agreement) pursuant to and in accordance with the provisions of the
Servicing Agreement.

     9.05 Restoration of Rights and Remedies. If any Controlling Party or Senior
Certificate Holder has instituted any proceeding to enforce any right or remedy
under this Trust Deed and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to such Controlling Party or Senior
Certificate Holder, then and in every such case the Trustee, and each
Controlling Party or such Senior Certificate Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of such
Controlling Party or Senior Certificate Holder shall continue as though no such
proceeding had been instituted.

     9.06 Rights and Remedies Cumulative. No right or remedy herein conferred
upon or reserved to the Trustee, the Controlling Parties and every Senior
Certificate Holder (except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Trust Certificates) is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                                      -49-

<PAGE>

     9.07 Delay or Omission Not Waiver. No delay or omission of the Trustee, the
Controlling Parties or any Senior Certificate Holder to exercise any right or
remedy accruing under this Trust Deed shall impair any such right or remedy or
constitute a waiver of any such right or remedy or an acquiescence therein.
Every right and remedy given by this Trust Deed or by law to the Trustee, the
Controlling Parties or any Senior Certificate Holder may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee, the
Controlling Parties or such Senior Certificate Holder.

     9.08 Waiver of Stay or Extension Laws. The Trustee covenants (to the extent
that it may lawfully do so) that it shall not at any time insist upon, or plead,
or in any manner whatsoever claim or take the benefit or advantage of, any law
wherever enacted, now or at any time hereafter in force, providing for any
appraisement, valuation, stay, extension or redemption, which may affect the
covenants in, or the performance of, this Trust Deed; and the Trustee (to the
extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenants that it shall not hinder, delay or
impede the execution of any power herein granted to the Enhancers or Certificate
Holders, but shall suffer and permit the execution of every such power as though
no such law had been enacted.

     9.09 Limitation on Suits. Following the application of the net proceeds of
the Trust Property (other than the Charitable Property) in accordance with
Section 9.02, after payment of all other claims ranking in priority thereto, the
Certificate Holders shall not take any further steps against the Trustee to
recover any sum in respect of the Trust Certificates still unpaid and the
Trustee's liability for any such sum still unpaid shall be extinguished. A
liability arising under or in connection with this Trust Deed, the Trust
Certificates or any Transaction Document can be enforced against the Trustee
only to the extent to which it can be satisfied out of Trust Property out of
which the Trustee is actually indemnified for the liability. This limitation of
the Trustee's liability applies notwithstanding any other provision of this
Trust Deed, the Trust Certificates or the Transaction Documents and extends to
all liabilities and obligations of the Trustee in any way connected with any
representation, warranty, conduct, omission, agreement or transaction related to
this Trust Deed, the Senior Trust Certificates and the Transaction Documents.

     The provisions of this Section shall not apply to any obligation or
liability of the Trustee to the extent of and arising from the Trustee's fraud,
willful misconduct, negligence or breach of trust. No Certificate Holder shall
be entitled to petition or take any step for the winding up of the Trust or
Trustee.

     9.10 Accumulation Events.

     (a)  Each of the following events shall constitute an Accumulation Event
("Accumulation Event") if such event shall occur and be continuing:

          (i)   failure by Petrobras to satisfy the Quarterly Export Requirement

          (ii)  any Petrobras Default, U.S. Seller Default, Petrobras Finance

         Ratio, for any Quarterly Delivery Period;

                  (iv)  the Junior Certificate Interest at any time shall be
         less than the sum of U.S.$75,000,000 plus 10% of the original aggregate
         principal amount of any Series of Senior Trust Certificates issued
         after the Closing Date which at such time has any principal amount
         remaining outstanding;

                  (v)   in the event that funds in the Reserve Account are
         applied on any Payment Date, failure of the Reserve Account to be fully
         funded in an amount equal to the Reserve Account Cap on the next
         following Payment Date; or

                  (vi)  a Default (as such term is defined in any Insurance and
         Reimbursement Agreement) has occurred and is continuing under such
         Insurance and Reimbursement Agreement.

         Upon the occurrence of an Accumulation Event, the Trustee shall (A)
direct the Depositary Bank to retain and transfer amounts held in the Purchased
Receivables Account in accordance with Section 5.06(c) and (B) promptly provide
written notice of such Event (identifying the event that gave rise to such
Accumulation Event and stating whether such event is also a Specified Event
and/or an Incipient Termination Event) (an "Accumulation Event Notice") to the
Certificate Holders, the Enhancers, Petrobras Finance and the Servicer (with a
copy to Petrobras).

         (b)      At any time during a Quarterly Delivery Period when an
Accumulation Event has occurred and is continuing and until such time as the
Trustee has directed the Depositary Bank to release all amounts held in the
Retention Account pursuant to Section 9.10(d) below, the Trustee shall, upon the
vote of Controlling Parties representing at least 35% of the aggregate principal
amount of the outstanding Senior Trust Certificates, by written notice to
Petrobras Finance and the Enhancers (with a copy to Petrobras and the Servicer)

Trust Certificates in whole or in part (a "Mandatory Prepayment Event").

         (c)      (i)  Upon the occurrence of a Mandatory Prepayment Event, the
Trustee shall direct the Depositary Bank to apply all amounts held in the
Retention Account to the mandatory prepayment of the outstanding Senior Trust
Certificates on the Payment Date immediately following the date of delivery of a
Mandatory Prepayment Notice, pro rata to each Series of Senior Trust
Certificates then outstanding, in accordance with the outstanding principal
amount thereof and to each installment thereof on a ratable basis.

                  (ii) So long as any Accumulation Event is continuing,
         Controlling Parties representing at least 35% of the aggregate
         principal amount of the outstanding Senior Trust Certificates may
         declare a Mandatory Prepayment Event and may, at the time of any such
         declaration, specify that such mandatory prepayment shall continue
         automatically for future Quarterly Delivery Periods so long as such
         Accumulation Event continues. Such declaration in respect of future
         Quarterly Delivery Periods may be

                                      -51-

<PAGE>

         revoked by a vote of Controlling Parties representing at least 66?% of
         the aggregate principal amount of outstanding Senior Trust
         Certificates.

                  (iii) Notwithstanding anything contained in this paragraph (c)
         to the contrary, during the first twelve Quarterly Delivery Periods
         following the Closing Date, no application of amounts in the Retention
         Account shall be permitted as a result of the occurrence of either of
         the Accumulation Events set forth in Section 9.10(a)(iii), unless the
         failure to meet such ratio has continued for two consecutive Quarterly
         Delivery Periods.

         (d)      If at any time during a Quarterly Delivery Period the Trustee
receives written notice from the Servicer that all of the Accumulation Cessation
Conditions in respect of any Accumulation Event have been satisfied (an
"Accumulation Cessation Notice"), the Trustee shall withdraw all amounts held in
the Retention Account on the date of receipt of such Notice and shall purchase
from Petrobras Finance additional Purchased Receivables pursuant to and in
accordance with Section 2.03(b) of the Receivables Purchase Agreement.

         The following conditions shall constitute Accumulation Cessation
Conditions (each, an "Accumulation Cessation Condition"):

                  (i)   a Mandatory Prepayment Event has not been declared on or
         prior to the date that all other Accumulation Cessation Conditions have
         been satisfied in respect of such Accumulation Event;

                  (ii)  the Accumulation Event has been cured and there are no
         other Accumulation Events, Specified Events or Termination Events
         existing;

                  (iii) the Senior Coverage Ratio is at least equal to the
         Required Senior Coverage Ratio, and the Third Party Coverage Ratio is
         at least equal to the Required Third Party Coverage Ratio, in each
         case, for the two immediately preceding Quarterly Delivery Periods; and

                  (iv)  Petrobras has satisfied the Quarterly Export Requirement
         for the two immediately preceding Quarterly Delivery Periods.

         (e)      If a U.S. Seller Default has occurred and as a result thereof,
Collections in respect of Receivables from the Sale of Eligible Products by the
U.S. Seller are not deposited into the Collection Account in accordance with the
terms of the Product Sale Agreement, then the Trustee shall, if so directed by
Controlling Parties representing at least 35% of the aggregate principal amount
of the outstanding Senior Trust Certificates, provide written notice (with a
copy to the Servicer) to each Specified Buyer of Eligible Products from the U.S.
Seller instructing such Specified Buyer from and after the date of such notice
to pay or cause to be paid all amounts in respect of such Sales to the account
of the Trust so designated in such notice.

              (i)  a Petrobras Default occurs and is continuing; or

              (ii) a Petrobras Finance Default occurs and is continuing.

         (b)  Upon the occurrence of an Incipient Termination Event, the Trustee
shall (i) promptly provide written notice of such Event (identifying the event
that gave rise to such Incipient Termination Event and stating that such event
is also a Specified Event and an Accumulation Event) (an "Incipient Termination
Event Notice") to the Certificate Holders, the Enhancers, Petrobras Finance and
the Servicer (with a copy to Petrobras) and (ii) act in accordance with Sections
9.01 and 9.10.

         (c)  If, at any time during the occurrence and continuation of an
Incipient Termination Event, Controlling Parties representing at least 35% of
the aggregate principal amount of outstanding Senior Trust Certificates instruct
the Trustee to declare an Acceleration Event, a Termination Event (a
"Termination Event") shall automatically be deemed to occur. Upon such
Termination Event, the Trustee shall promptly provide written notice of such
Event (identifying the event that gave rise to such Termination Event) (an
"Termination Event Notice") to Petrobras Finance and the Servicer (with a copy
to Petrobras).

         (d)  At any time during the occurrence of a Termination Event, the
Trustee shall, at the direction of Controlling Parties representing at least 35%
of the aggregate principal amount of outstanding Senior Trust Certificates,
notify Petrobras Finance in writing (with a copy to Petrobras and the Servicer)
(a "Contract Termination Notice") that the Receivables Purchase Agreement is
subject to termination; provided, that the Receivables Purchase Agreement shall
be subject to termination automatically if a Bankruptcy Event occurs with
respect to Petrobras (other than a Bankruptcy Event solely with respect to a
Material Subsidiary of Petrobras) or Petrobras Finance; provided further,
however, that no termination of the Receivables Purchase Agreement shall be or
become effective until such time as the RPA Termination Price shall have been
deposited into the Purchased Receivables Account (or such replacement account
therefor as the Trustee may designate). On the date of receipt of the RPA
Termination Price from Petrobras Finance pursuant to Section 5.05 of the
Receivables Purchase Agreement, the Trustee shall apply such purchase price,
together with all other amounts held in the Trust Accounts, in accordance with
the order of priority set forth in Section 9.02.

                  (ii)  the Trustee and each Enhancer, so long as such Enhancer
         is the Controlling Party of its respective Series, shall have received
         written confirmation from the Depositary Bank that a new U.S. Seller
         Account has been established in accordance with the terms of the
         Depositary Agreement;

                  (iii) all Buyers to whom the U.S. Seller has Sold or intends

                                   THE TRUSTEE

         10.01    Duties of Trustee.

         (a)      The duties and liabilities of the Trustee are as follows:

                  (i)   the Trustee need perform only those duties that are
         specifically set forth in this Trust Deed and the other Transaction
         Documents and no others; the Trustee shall not, by virtue of its or any
         of its Affiliates acting in any other capacity, be deemed to have other
         duties or responsibilities or be deemed to be held to a standard of
         care other than as expressly provided with respect to each such
         capacity, and no implied covenants or obligations of the Trustee shall
         be read into this Trust Deed and the other Transaction Documents; and

                  (ii)  in the absence of bad faith or willful misconduct on its
         part, the Trustee may conclusively rely, as to the truth of the
         statements and the correctness of the opinions expressed therein, upon
         certificates or opinions furnished to the Trustee and conforming to the
         requirements of this Trust Deed and the other Transaction Documents
         unless an Authorized Officer of the Trustee has actual knowledge that
         such statements or opinions are false. The Trustee shall examine such
         certificates and opinions to determine whether they conform to the
         requirements of this Trust Deed and the other Transaction Documents.

         (b)      No provision of this Trust Deed shall be construed to relieve
the Trustee from liability for any damage, loss, costs or expenses whatsoever to
or by the Certificate Holders or the Enhancers at any time caused by the
Trustee's own negligence, willful misconduct, bad faith or breach of trust
except that:

                  (i)   this paragraph (b) does not limit the effect of
         paragraph (a) of this Section;

                  (ii)  the Trustee shall not be liable in its individual
         capacity or otherwise with respect to any action it takes or refrains
         from taking in good faith in accordance with this Trust Deed or at the
         direction of the Controlling Parties, in conformity with the
         requirements of this Trust Deed and the other Transaction Documents;

                  (iii) no provision of this Trust Deed shall require the
         Trustee to expend or risk its own funds or otherwise incur any
         financial liability in the performance of any of its duties hereunder,
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that repayment of such funds or
         adequate indemnity against such risk or liability is not reasonably
         assured to it;

                                      -55-

<PAGE>

                  (iv) in no event shall the Trustee be liable for indirect,
         special, incidental or consequential losses or damages of any kind
         whatsoever, including lost profits due to its performance under any
         Transaction Document to which it is a party, even if it has been
         advised of the possibility thereof and regardless of the form of action
         in which such damages are sought; and

                  (v)  the Trustee shall have no duty (A) to cause or arrange
         any recording, filing, or depositing of this Trust Deed or any
         agreement referred to herein or any financing statement or continuation
         statement evidencing a security interest, or to cause or arrange the
         maintenance of any such recording or filing or depositing or to any
         rerecording, refiling or redepositing of any thereof, (B) to arrange
         any insurance, (C) to cause or arrange the payment or discharge of any
         tax, assessment, or other governmental charge or any lien or
         encumbrance of any kind owing with respect to, assessed or levied
         against, any part of the Trust Property other than from funds available
         in the Trust Accounts, or (D) to confirm or verify the contents of any
         reports or certificates of the Servicer delivered to the Trustee
         pursuant to this Trust Deed that are believed by the Trustee to be
         genuine and to have been signed or presented by the proper party or
         parties.

         (c)      Whether or not therein expressly so provided, every provision
of this Trust Deed relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 10.01 and Section 9.09.

         10.02    Rights of Trustee. Subject to the provisions of Section 10.01:

         genuine and to have been signed or presented by the proper Person
         (whether obtained by the Trustee, any Agent or any other party to a
         Transaction Document). The Trustee need not investigate any fact or
         matter stated in the document.

                  (b)  Before the Trustee acts or refrains from acting, it may
         require an opinion of counsel provided that such opinion is rendered

         liable for any action it takes or omits to take in good faith in
         reliance on any opinion of counsel.

                  (c)  The Trustee may employ or retain such counsel,
         accountants, appraisers, agents or other experts or advisers as it may
         reasonably require for the purpose of determining and discharging its
         rights and duties hereunder and shall not be responsible for any
         misconduct on the part of any of them appointed with due care.

                  (d)  The Trustee may act and rely and shall be protected in
         acting and relying in good faith on the opinion or advice of or
         information obtained from any counsel, accountant, appraiser, agents or
         other expert or adviser (whether obtained by the Trustee, any Agent or
         any other party to a Transaction Document) in relation to any matter
         arising in the administration of the trusts hereof.

                  (e)  The Trustee shall not be liable for any action it takes
         or omits to take in good faith that it believes to be authorized or
         within its rights or powers.

                  (f)  The Trustee may consult with counsel of its selection and
         the advice of such counsel or any opinion of counsel shall be full and

         suffered or omitted by it hereunder in good faith and in reliance
         thereon.

                  (g)  The Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Trust Deed at the request
         or direction of any Controlling Party, Senior Certificate Holder or
         other parties to the Transaction Documents pursuant to this Trust Deed,
         unless such Controlling Party, Senior Certificate Holder or parties to
         the Transaction Documents shall have offered to the Trustee reasonable
         security or indemnity against the costs, expenses and liabilities which
         might be incurred by it in compliance with such request or direction.

                  (h)  The 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, direction,
         consent, order, note, other evidence of indebtedness or other paper or
         document, but the Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit,
         and shall incur no liability or additional liability of any kind by
         reason of such inquiry or investigation.

                  (i)  The Trustee shall not be deemed to have notice of any
         Specified Event or Accumulation Event unless an Authorized Officer of
         the Trustee has actual knowledge thereof or unless written notice of
         any event which is in fact such a Specified Event is received by the
         Trustee at the Specified Office of the Trustee, and such notice
         references the Trust Certificates or this Trust Deed.

                  (j)  The Trustee shall have regard to the interests of the
         Certificate Holders and in particular, but without prejudice to the
         generality of the forgoing, shall not have regard to the consequences
         of the exercise of its powers, trusts, authorities or discretions for
         individual Certificate Holders resulting from their being for any
         purpose domiciled or resident in, or otherwise connected with, or
         subject to the jurisdiction of, any particular territory and the
         Trustee shall not be entitled to require, nor shall any holder of a
         Trust Certificate be entitled to claim, from the Trustee, any
         indemnification or payment in respect of any Tax consequence of any
         such exercise upon individual Senior Certificate Holders.

                  (k)  The Trustee may execute any of the trusts, fiduciary
         rights or powers or perform any duties under this Trust Deed either
         directly or by or through agents, including the Trust Administrator, or
         attorneys. The Trustee shall not be responsible for any misconduct or
         negligence on the part of any agent or attorney appointed with due care
         by it under this Trust Deed.

                  (l)  The Trustee shall not be liable to any Certificate
         Holders by reason of having accepted as valid or not having rejected,
         in good faith, any Trust Certificate as such and subsequently found to
         be forged or not authentic.

                  (m) The Trustee as between itself and the Certificate Holders
         shall have full power to determine all questions and doubts arising in
         relation to any of the provisions of this Trust Deed and every such
         determination, whether made upon a question actually raised or implied
         in the acts or proceedings of the Trustee, shall be conclusive and
         shall bind the Trustee and the Certificate Holders.

                  (n) The Trustee shall (save as expressly otherwise provided
         herein or in the Transaction Documents) as regards all the trusts,

         and uncontrolled discretion as to the exercise or non-exercise thereof
         and the Trustee shall not be responsible for any loss, costs, damages,

         non-exercise thereof.

                  (o) Any consent given by the Trustee for the purposes of this
         Trust Deed and any other Transaction Document may be given on such

         require and, notwithstanding anything to the contrary contained in this
         Trust Deed, the Trust Certificates or any Transaction Document, may be
         given retrospectively.

                  (p) Where it is necessary or desirable for any purpose in
         connection with this Trust Deed to convert any sum from one currency to
         another it shall (unless otherwise provided by this Trust Deed or
         required by law) be converted at such rate or rates, in accordance with
         such method and as at such date for the determination of such rate of
         exchange, as may be specified by the Trustee in its absolute discretion
         as relevant and any rate, method and date so specified shall be binding
         on the Certificate Holders.

money received by it hereunder except as otherwise provided in this Trust Deed
or the Trust Certificates or any other Transaction Document.

it by this Trust Deed and any other Transaction Document are entitled to be
indemnified out of the proceeds of the Trust Property for any loss, liability,
obligation, claim, damage or expense (including without limitation attorneys'

connection with, the acceptance or administration of this trust or any of the
other Transaction Documents, including the costs and expenses of defending
themselves against any claim or liability in connection with the exercise or
performance of any of their powers or duties hereunder or under the other

thereof in another currency) as set forth in its most recent audited accounts or
such other amount as may be required under applicable law of the Cayman Islands
from time to time and such successor Trustee shall not otherwise cause the Trust

the Trust Property, for insuring the Trust Property or for the payment of Taxes
or Liens upon the Trust Property or otherwise as to the maintenance of the Trust
Property.

which was included in the percentage of Controlling Parties which requested or
consented to such action may, by filing written notice with the Trustee at the
Corporate Trust Office, revoke its request or consent to such action and if such
revocation results in the request or consent of less than the relevant required

revoked; provided that any such revocation shall not affect the indemnity, if
any, offered by such Controlling Party or Senior Certificate Holders to the
Trustee for any actions taken by the Trustee prior to such revocation.

Certificates. The Trustee covenants and agrees, and each Junior Certificate
Holder, by its acceptance of such Junior Trust Certificate, likewise covenants

right of payment to the Senior Trust Certificates and to the prior indefeasible
payment in full in cash of all Senior Trust Certificates and the payment of all
Guaranty Reimbursements, whether outstanding on the date of this Trust Deed or
thereafter created, incurred or assumed.

<PAGE>

           (i)   the Senior Certificate Holders and the Enhancers shall be
     entitled to receive payment in full in cash of all amounts due or that may
     become due on or in respect of any and all Senior Trust Certificates and
     any Guaranty Reimbursements before the Junior Certificate Holders are
     entitled to receive any direct or indirect payment or distribution of any
     kind or character;

           (ii)  any direct or indirect payment or distribution of assets of any
     kind or character, whether in cash property, securities, by set-off or
     otherwise, to which the Junior Certificate Holders or any representative of
     the Junior Certificate Holders would be entitled but for the provisions of
     this Article shall in all cases be paid by the liquidating trustee or agent
     or other Person making such payment or distribution, whether a trustee in
     bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
     Senior Certificate Holders or the Enhancers, if applicable, or their
     representatives, ratably according to the aggregate amounts remaining
     unpaid on account of the Senior Trust Certificates, to the extent necessary
     to make payment in full of all Senior Trust Certificates after giving
     effect to any concurrent payment or distribution to the Senior Certificate
     Holders;

           (iii) in the event that, notwithstanding the foregoing provisions of
     this Article XIII, the Junior Certificate Holders or any representative of
     the Junior Certificate Holders shall have received any payment or
     distribution of assets of the Trust Property of any kind or character
     (including, without limitation, by way of set-off or counterclaim) before
     all Senior Trust Certificates and any Guaranty Reimbursements are paid in
     full in cash, then and in such event such payment or distribution shall be
     immediately paid over or delivered forthwith by such Junior Certificate
     Holder or representative of such Junior Certificate Holder, and held in
     trust for the benefit of the Senior Certificate Holders or the Enhancers,
     if applicable, to the trustee in bankruptcy, receiver, liquidating trustee,
     custodian, agent or other Person making payment or distribution of assets
     of the Trust Property for application to the payment of all Senior Trust
     Certificates; and

           (iv)  if any Junior Certificate Holders shall have failed to file
     proofs of interest with respect to Junior Trust Certificates at least 15
     calendar days prior to the deadline for any such filing, any such Junior
     Certificate Holder shall execute and deliver such powers of attorney,
     assignments or other instruments as the Senior Certificate Holders or their
     representatives may reasonably request to file such proofs of interest.

     13.03 No Payment. Each Junior Certificate Holder hereby agrees that, unless
and until the principal of and any other amounts then due on, or to become due
on, the Senior Trust Certificates or under the Insurance Documents, if
applicable, shall have been indefeasibly paid in full in cash, (i) subject to
the last paragraph in this Section 13.03, no payment on account of the principal
of, interest, premium (if any) on, or other amounts due on the Junior Trust

whether by the Trustee or otherwise and (ii) no Junior Certificate Holder shall

<PAGE>

collateral security for the Junior Trust Certificates.

     In the event that, notwithstanding the foregoing provisions of this Section
13.03, any Junior Certificate Holder shall have received any payment prohibited
by the foregoing provisions of this Section 13.03 including, without limitation,
any such payment arising out of the exercise by any Junior Certificate Holder or
their representatives of a right of set-off or counterclaim or similar action,
then, and in any such event, such payment shall be held in trust for the benefit
of the Senior Certificate Holders and the Enhancers, and shall be immediately
paid over or delivered to, the Trustee for the benefit of the Senior Certificate
Holders and the Enhancers or, if applicable, to the trustee in bankruptcy,
receiver, liquidating trustee, custodian or other Person making payment or
distribution of the assets of the Trust Property for application to the payment
of all Senior Trust Certificates and all payments due under the Insurance
Documents.

     Notwithstanding anything to the contrary in this Section 13.03, the Junior
Certificate Holders shall be entitled to receive, and the Trustee shall be
entitled to make, (i) payments of interest on the Junior Trust Certificates
solely in accordance with and in such amounts as provided in Section 2.02 hereof
and (ii) payments for the prepayment of the Junior Trust Certificates solely in
accordance with and in such amounts as provided in Sections 3.01(b) and 3.07
(c).

payment in full of all Senior Trust Certificates and all amounts due under the
Insurance Documents, the Junior Certificate Holders shall be subrogated to the
rights of the Senior Certificate Holders and the Enhancers, if applicable, to
receive payments and distributions of cash, property and securities applicable
to such Senior Trust Certificates, until such time as all amounts owing on the
Junior Trust Certificates shall be paid in full in cash. For purposes of such
subrogation, no payment or distributions to the Senior Certificate Holders or
the Enhancers by or on behalf of the Trustee or by or on behalf of the Junior
Certificate Holders by virtue of this Article XIII which otherwise would have
been made to the Junior Certificate Holders shall, as between the Trustee and
its creditors other than Senior Certificate Holders and the Enhancers, if
applicable, be deemed to be a payment or distribution by the Trustee to or on
account of Senior Certificate Holders or the Enhancers.

     13.05 Provisions Solely to Define Relative Rights. The provisions of this
Article XIII are, and are intended solely, for the purpose of defining the
relative rights of the Junior Certificate Holders on the one hand and the Senior
Certificate Holders and the Enhancers on the other hand. Nothing contained in
this Article XIII or elsewhere in this Trust Deed or in the Trust Certificates
is intended to or shall (i) impair, as between the Trustee and the Junior
Certificate Holders, the obligation of the Trustee, which is absolute and
unconditional, to pay to the Junior Certificate Holders the principal and
interest on the Junior Trust Certificates, as the case may be, as and when the
same shall become due and payable in accordance with their terms, or (ii) affect
the relative rights against the Trustee of the Junior Certificate Holders and
creditors of the Trustee other than the Senior Certificate Holders and the
Enhancers, or (iii) prevent the Trustee from exercising all remedies otherwise
permitted by applicable law under this Agreement,

                                      -70-

<PAGE>

subject to the rights, if any, under this Article XIII of the Senior Certificate
Holders and the Enhancers.

     13.06 Trustee to Effectuate Subordination. Each Junior Certificate Holder
by acceptance of a Junior Trust Certificate authorizes and directs the Trustee
on behalf of such Junior Certificate Holder to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article XIII and appoints the Trustee as the attorney-in-fact of such Junior
Certificate Holder for any and all such purposes, including, the immediate
filing of a claim for the unpaid balance of its Junior Trust Certificates
pursuant to this Trust Deed in the form required in said proceedings and the
causing of said claim to be approved.

     13.07 No Waiver of Subordination Provisions.

     (a)   No right of any present or future Senior Certificate Holder or
Enhancer to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the
Trustee or by any act or failure to act, in good faith, by any Certificate
Holders or any Enhancer, or by any non-compliance by the Trustee with the terms,
provisions and covenants of this Trust Deed, regardless of any knowledge thereof
any such Certificate Holder or Enhancer may have or be otherwise charged with.

     (b)   Without in any way limiting the generality of paragraph (a) of this
Section, subject to Article XI, any one or more of the following may occur at
any time and from time to time, without the consent of or notice to the Junior
Certificate Holders, without incurring responsibility to the Junior Certificate
Holders and without impairing or releasing the subordination or other benefits
provided in this Article XIII, or the obligations hereunder of the Junior
Certificate Holders to the Senior Certificate Holders and the Enhancers: (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew, exchange, amend, increase or alter, the Senior Trust Certificates or
the terms of any instrument evidencing the same or any agreement under which
Senior Trust Certificates are outstanding or any liability of any obligor
thereon, (ii) sell, exchange, release or otherwise deal with any assets of the
Trust Property, (iii) settle or compromise any Senior Trust Certificates or any
liability of any obligor thereon or release any Person liable in any manner for
the collection of Senior Trust Certificates, and (iv) exercise or refrain from
exercising any rights against the Trustee and any other Person.

     13.08 Specific Performance. Each of the Senior Certificate Holders and the
Enhancers may demand specific performance of the terms of subordination in this

     14.01 Financial Guaranty Insurance Policies. The Trustee hereby agrees that
all proceeds of the Financial Guaranty Insurance Policies shall be applied in
accordance with the terms of this Trust Deed to all unpaid amounts of scheduled
principal and interest which are due and payable in respect of the relevant
Series of Senior Trust Certificates. The Trustee shall hold the Financial
Guaranty Insurance Policies in trust, and shall hold any proceeds of any claim
upon the Financial Guaranty Insurance Policies in trust solely for the use and
benefit of the Senior Certificate Holders of the relevant Series.

     14.02 Claims Upon the Financial Guaranty Policies.

     (a)   If the Trustee determines pursuant to Section 5.08(a) that the amount
of funds available as of any Cut-Off Date is insufficient to pay the full amount
of principal and interest then due and payable on any Series of Senior Trust
Certificates on the related Payment Date (without regard to any acceleration of
payment of the Senior Trust Certificates) after payment of any Administrative
Expenses in accordance with Section 5.08(b), the Trustee shall (x) submit, if
applicable, to each relevant Enhancer a duly completed and executed notice for
payment and assignment in the forms of Exhibit A and Exhibit B, respectively, to
the relevant Financial Guaranty Insurance Policy, as provided by such Financial
Guaranty Insurance Policy, setting forth all of the information specified
therein (including, without limitation, the amount of any deficiency in the
principal and interest due on the relevant Series of Senior Trust Certificates)
on or prior to such Payment Date and (y) confirm to the relevant Senior
Certificate Holders that such notice and assignment has been Received (as such
term is defined in the relevant Financial Guaranty Insurance Policy). In
accordance with the terms of the respective Financial Guaranty Insurance Policy,
each relevant Enhancer shall pay the amount of such deficiency pursuant to the
relevant Financial Guaranty Insurance Policy in immediately available funds to
the Senior Trust Certificate Account no later than 12:00 noon, New York City
time, on the later of (i) the related Payment Date in respect of which a notice
of payment and assignment shall have been Received (as such term is defined in
the relevant Financial Guaranty Insurance Policy) and (ii) the third Business
Day following the Business Day on which the relevant Enhancer shall have
received the notice of payment (which day shall in no event precede the Cut-Off
Date relating to such Payment Date).

     (b)   Any funds received by the Trustee as a result of any claim under the
Financial Guaranty Insurance Policies shall be applied by the Trustee ratably to
the payment of interest on, or principal of, the Series of Senior Trust
Certificates to which such claim and payment under the relevant Financial
Guaranty Insurance Policy relates.

     (c)   The Trustee shall keep a complete and accurate record of all funds
deposited by the Enhancers into the Senior Trust Certificate Account and the
allocation of such funds to payment of interest on and principal of the Senior
Trust Certificates. The Trustee will respond to the Enhancers' requests for
information regarding payments made pursuant to the Financial Guaranty Insurance
Policies as promptly as possible. Each of the Enhancers shall have the right to
inspect such records at reasonable times upon one Business Days' prior notice to
the Trustee.

     (d)   Subject to and conditioned upon payment of any interest or principal
with respect to the Senior Trust Certificates by or on behalf of any Enhancer in
respect of its Financial Guaranty Insurance Policy, the Trustee shall assign,
and the relevant Senior Certificate Holders shall be deemed to have agreed to
the assignment, to the relevant Enhancer all rights to payment of interest on,
principal of and/or additional amounts with respect thereto in respect of the
Senior Trust Certificates of its Series which are then required to be paid,
together with all other rights and remedies of the Trustee or the relevant
Series of Senior Trust Certificates (including all rights of the Trustee and
each relevant Senior Certificate Holder in the conduct of any related Insolvency
Proceeding (as defined in the relevant Financial Guaranty Insurance Policy)), to
the extent of all such payments made by such Enhancer and, so long as no
Enhancer Default has occurred and is continuing, and subject to the other
provisions contained herein and in the other Transaction Documents, each
Enhancer may exercise any option, vote, right, power or the like with respect to
the percentage of the aggregate outstanding principal amount of the Senior Trust
Certificates of the relevant Series to which its Financial Guaranty Insurance
Policy relates on behalf of all of the Senior Certificate Holders of such
Series, without any right on the part of the relevant Senior Certificate Holders
to receive prior written notice of any such exercise, or to require that the
Enhancer of such Series take or refrain from such exercise.

     14.03 Rights in Respect of Insolvency Proceedings.

     (a)   In the event that the Trustee has received a certified copy of a
final, nonappealable order (the "Final Order") of the appropriate court or other
body exercising jurisdiction in such Insolvency Proceeding (as such term is
defined in the relevant Financial Guaranty Insurance Policy) that any scheduled
payment of principal of or interest on any Senior Trust Certificate has been
voided in whole or in part as a preference payment under applicable bankruptcy,
insolvency, receivership or similar law in an Insolvency Proceeding, the Trustee
shall (i) deliver to each of the Enhancers (A) a certified copy of such court
order or other governmental body exercising jurisdiction in such Insolvency
Proceeding to the effect that the Trustee or any Senior Certificate Holder is
required to return any such payment or portion thereof prior to the expiration
of the term of the Financial Guaranty Insurance Policy because such payment was
voided under applicable bankruptcy law, with respect to which order the appeal
period has expired without an appeal having been filed, (B) a certificate of the
Trustee or such Senior Certificate Holder to the effect that the Final Order has
been entered and is not subject to any stay, and (C) an irrevocable assignment
properly completed and duly executed to the relevant Enhancer of the Senior
Certificate Holders' rights with respect to any such recovered payment in the
form attached to the Policy and (ii) notify the Senior Certificate Holders by
mail that, in the event that any Senior Certificate Holder's scheduled payment
is so recovered, such Senior Certificate Holder will be entitled to payment of
such recovered amounts pursuant to the terms of the relevant Financial Guaranty
Insurance Policy.

     (b)   The Trustee shall promptly notify each of the Enhancers and each
Rating Agency of either of the following as to which an Authorized Officer of
the Trustee has actual knowledge: (i) the commencement of any Insolvency
Proceeding by or against the Trustee in respect of the Trust and (ii) the making
of any claim in connection with any Insolvency Proceeding seeking the avoidance
as a preferential transfer (a "Preference Claim") of any payment of principal of
or interest on the Senior Trust Certificates. Each Senior Certificate Holder, by
its purchase of a Senior Trust Certificate, and the Trustee hereby agree that,
so long as an Enhancer Default shall not have occurred and be continuing, the
Enhancers acting together may at any time during the continuation of an
Insolvency Proceeding direct all matters relating to such Insolvency Proceeding,
pursuant to the terms of the relevant Financial Guaranty Insurance Policy. In
addition, and without limitation of the foregoing, as set forth in Section
14.04, the Enhancers shall be subrogated to, and each Senior Certificate Holder
and the Trustee hereby delegate and assign, to the fullest extent permitted by
law, the rights of the Trustee and each Senior Certificate Holder in the conduct
of any Insolvency Proceeding, including, without limitation, all rights of any
party to an adversarial proceeding with respect to any court order issued in
connection with any such Insolvency Proceeding.

     (c)   The Trustee shall furnish to the Enhancers its records evidencing the
payments of principal of and interest on the Senior Trust Certificates that have
been made by the Trustee and the dates on which such payments were made.

     14.04 Effect of Payments by the Enhancers; Subrogation.

     (a)   Anything herein to the contrary notwithstanding, any payment with
respect to principal of or interest on a Series of Senior Trust Certificates
that is made with moneys received pursuant to the terms of a Financial Guaranty
Insurance Policy shall not be considered payment by the Trustee of such Series
of Senior Trust Certificates, shall not discharge the Trustee in respect of its
obligation to make such payment and shall not result in the payment of or the
provision for the payment of principal of or interest on such Series of Senior
Trust Certificates hereunder. The Trustee acknowledges that without the need for
any further action on the part of the Enhancers, the Trustee or the Registrar
(i) to the extent any Enhancer makes payments, directly or indirectly, on
account of principal or interest on its Series of Senior Trust Certificates to
Senior Certificate Holders, such Enhancer will be fully subrogated to the rights
of such Senior Certificate Holders to receive such principal and interest from
the Trustee and will be deemed to the extent of the payments so made to be a
Senior Certificate Holder, and (ii) any Enhancer shall be paid such principal
and interest in its capacity as a Senior Certificate Holder until all such
payments by such Enhancer have been fully reimbursed, but only from the sources
and in the manner provided herein for the payment of such principal and
interest.

                                      -74-

     (b)   Without limiting the rights or interests of the Senior Certificate
Holders as otherwise set forth herein, and subject to Article IX, so long as no
Enhancer Default exists, the Trustee shall cooperate in all respects with any
reasonable request by the relevant Enhancer for action to preserve or enforce
such Enhancer's rights or interests under this Trust Deed, including, without
limitation, upon the occurrence and continuance of a Specified Event, a request
to take any one or more of the following actions:

           (i)   institute proceedings for the collection of all amounts then
     payable on the Senior Trust Certificates or under this Trust Deed in
     respect of the Senior Trust Certificates, enforce any judgment obtained and
     collect moneys adjudged due;

           (ii)  institute proceedings from time to time for the complete or
     partial foreclosure of this Trust Deed; and

           (iii) exercise any remedies and take any other appropriate action to
     protect and enforce the rights and remedies of the Enhancers hereunder.

     14.05 Financial Guaranty Insurance Policy Receipt. The Trustee shall
execute and deliver to each Enhancer and the Servicer a receipt for the relevant
Financial Guaranty Insurance Policy.

     14.06 Return of Financial Guaranty Insurance Policy. Upon the expiration of
the Term (as defined in the applicable Financial Guaranty Insurance Policy) of
the Policy, the Trustee shall return such Policy to the relevant Enhancer
together with a notice substantially in the form of Exhibit D to the relevant
Enhancer.

     14.07 Inconsistency. Notwithstanding the foregoing provisions of this
Article XIV, to the extent that there is any inconsistency between this Article
XIV and the Financial Guaranty Insurance Policies, the terms of the relevant
Financial Guaranty Insurance Policy will govern to the extent of such
inconsistency.

registered Certificate Holder so elects by giving written notice to such effect
designating such account which is received by the Trustee or a Paying Agent no

                     Definitions of Bunker Fuel and Fuel Oil

"Fuel Oil" means fuel oil that originates from residual fractions of
distillation units at the refinery and from other processes such as
deasphalting.

"Bunker Fuel" means marine fuels that are burned in the boilers or engines of
ships. Bunker Fuel is generally of two types:

     1. Intermediate Fuel Oil (IFO) or Marine Fuel (MF) - IFO or MF is a blended
oil with a viscosity between heavy fuel oil and cutter stock (middle
distillates) that is formulated to achieve a specific viscosity. IFOs are used
in ships' main engines and occasionally in auxiliary engines. The two most
common types of IFO are 380 cSt and 180 cSt. Approximately 80% of Petrobras'
bunker sales are comprised of these two categories.

     2. Marine Diesel Fuel (MDO) or Marine Gas Oil (MGO) - MDO or MGO is a light
distillate fuel frequently used in auxiliary engines and in the main engines of
military vessels. MDO or MGO command higher prices than IFO. Approximately 20%
of Petrobras' bunker sales are comprised of MDO or MGO.

     For the purpose of all Transaction Documents, an "export" of Bunker Fuel
shall include any sale of Bunker Fuel in Brazil to ships owned by non-Brazilian
companies.

                       PF Export Receivables Master Trust

     [______]% SENIOR TRUST CERTIFICATE, SERIES [__], DUE [______]

     This Senior Trust Certificate is one of a duly authorized issue of [__]%
Senior Trust Certificates, Series [__], due [___] of the Trustee issued under
the Trust Deed, to which Trust Deed reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Trustee and the Senior Certificate Holders and of the terms upon which
the Senior Trust Certificates are, and are to be, authenticated and delivered.
The Senior Trust Certificates of this Series are limited in aggregate principal
amount to U.S.$[_________].

     1. Payment of Interest, Principal and Additional Amounts. The Trustee of
the PF Export Receivables Master Trust (the "Trustee") promises to pay interest
on the aggregate unpaid principal amount of this Senior Trust Certificate at
[______]% per annum (the "Certificate Rate of Interest") until the Final Payment
Date and to pay Additional Amounts in accordance with the Trust Deed. The
Trustee shall pay principal of this Senior Trust Certificate in accordance with
the Amortization Schedule attached hereto and shall pay interest and Additional
Amounts, if any, in each case quarterly on March 1, June 1, September 1 and
December 1 of each year (each a "Payment Date"), or if any such day is not a
Business Day, on the next succeeding Business Day. Payments of interest will
commence on [__________]. Payments of principal will commence on [__________].
The Final Scheduled Principal Payment Date is [____]. Interest shall accrue on
the outstanding principal amount of each Senior Trust Certificate from and
including the date of issuance of such Senior Trust Certificate to, but
excluding the Final Payment Date. The Final Payment Date shall be either the
Final Scheduled Principal Payment Date or such other date upon which the
principal amount of this Series of Senior Trust Certificates is paid in full.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. To the extent permitted by applicable law, any payments due and not
punctually paid on or in respect of the Senior Trust Certificates shall bear
interest until paid at the applicable Certificate Rate of Interest plus [ ]%
(the "Default Interest Rate").

     Except as provided below, the Trustee shall make all payments of amounts
due on the Senior Trust Certificates, without withholding or deduction of any
present or future taxes, duties, levies, imposts, assessments or other
governmental charges (including penalties, interest and other liabilities
related thereto) of any nature imposed by Brazil, the Cayman Islands, the United
States or any jurisdiction from or through which payment is made in respect of
the Senior Trust Certificates, or any political subdivision of any such
jurisdiction (collectively, "Taxes"). If any such Taxes are so imposed, the
Trustee shall pay the Senior Certificate Holders such additional amounts as are
necessary to ensure that they receive the same amount as they would have
received had no such withholding or deduction been imposed (such amounts,
"Additional Amounts"). The Trustee shall not, however, pay any Excluded
Additional Amounts, as defined and set forth in Section 2.02(e) of the Trust
Deed.

     The Trustee shall pay any stamp, administrative, excise or property Taxes
arising in a taxing jurisdiction in connection with the Senior Trust
Certificates and shall indemnify the

                                 Exhibit A-1-5

<PAGE>

Senior Certificate Holders for any such stamp, administrative, excise or
property Taxes paid by Senior Certificate Holders.

     2.   Method of Payment. All payments in respect of the Senior Trust
Certificates shall be made at the Specified Office of the Paying Agent in The
City of New York and, subject to any fiscal or other laws and regulations
applicable thereto, at the specified offices of any other Paying Agent appointed
by the Trustee for such purpose. Payment in respect of principal and interest on
any Payment Date with respect to any Senior Trust Certificate shall be made to
the Person in whose name such Senior Trust Certificate is registered on the
Regular Record Date immediately preceding the applicable Payment Date. Payments
with respect to any Senior Trust Certificate shall be made by a dollar check
drawn on a bank in The City of New York and mailed to such Person's address
registered with the Trustee or, in the case of a registered holder of at least
$1,000,000 principal amount of Senior Trust Certificates, by wire transfer to a
dollar account maintained by the payee with a bank in the United States so long
as the registered Senior Certificate Holder so elects by giving written notice
to such effect designating such account which is received by the Trustee or a
Paying Agent no later than the Regular Record Date immediately preceding such
Payment Date. Unless such designation is revoked, any such designation made by
such Senior Certificate Holder with respect to such Senior Trust Certificates
shall remain in effect with respect to any future payments with respect to such
Senior Trust Certificate payable to such Senior Certificate Holder. Only the
final installment of principal on the Senior Trust Certificates, whether on the
Final Scheduled Principal Payment Date or otherwise, shall be payable upon
surrender of any Senior Trust Certificate at the Specified Office of the Trustee
or at the specified offices of any Paying Agent.

     3.   Paying Agent, Transfer Agent and Registrar. The Trustee shall cause to
be maintained an office or agency in The City of New York where the Senior Trust
Certificates may be presented for registration of transfer or for exchange. The
Trustee shall cause to be maintained an office or agency where the Senior Trust
Certificates may be presented and surrendered for payment. The Registrar shall
keep a register ("Register") of Senior Trust Certificates and of their transfer
and exchange. The Trustee may, at its discretion, appoint one or more agents
(each, a "Paying Agent" and, collectively, the "Paying Agents") for the payment
of any and all amounts due and payable by the Trustee from time to time in
respect of the Senior Trust Certificates, and the Trustee may, at its
discretion, appoint one or more agents (each, a "Transfer Agent" and,
collectively, the "Transfer Agents") for the transfer and exchange of the Senior
Trust Certificates, at such place or places as the Trustee may determine,
provided, however, that there shall at all times be a Paying Agent, Transfer
Agent and Registrar in the Borough of Manhattan, The City of New York. So long
as the Senior Trust Certificates are listed on the Luxembourg Stock Exchange and
the rules of the Luxembourg Stock Exchange so require, there shall be maintained
a Paying Agent and a Transfer Agent in Luxembourg (the "Luxembourg Paying
Agent"). [Initially, Citibank, N.A. shall act as the Paying Agent, Registrar and
Transfer Agent and Kredietbank S.A. Luxembourgeoise shall act as the Luxembourg
Paying Agent and Luxembourg Listing Agent.]

     4.   Additional Senior Trust Certificates. Subject to the requirements set
forth in the Trust Deed, the Trustee shall be permitted to issue additional
senior trust certificates by Supplemental Trust Deed after the date of the
issuance of this Senior Trust Certificate.

                                 Exhibit A-1-6

<PAGE>

     5.   [Guarantees. Payment of principal and interest is guaranteed by
[________] as described in the Supplemental Trust Deed relating to this Series
of Senior Trust Certificates.]

     6.   Optional Prepayment. Any Series of Senior Trust Certificates may be
subject to optional prepayment in whole but not in part in the event that
Petrobras Finance elects to repurchase all or a portion of the Trustee's rights
to Purchased Receivables to be Generated pursuant to Section 5.1(a) of the
Receivables Purchase Agreement. In such event, the Trustee shall prepay the
Senior Trust Certificates of such Series in an amount equal to the sum of (i)
the outstanding principal amount of the Senior Trust Certificates to be prepaid
at the time of prepayment, plus (ii) accrued and unpaid interest thereon, and
Additional Amounts, if any, in respect of such Series of Senior Trust
Certificates, to the Prepayment Date, plus (iii) 0.50% times the outstanding
principal amount of the Senior Trust Certificates to be prepaid at the time of
prepayment (the "Make Whole Premium") plus (iv) all other amounts payable by the
Trustee in respect of such Senior Trust Certificates.

     7.   Tax Prepayment. The Trustee shall prepay all of the Senior Trust
Certificates, in whole but not in part, in the event that Petrobras Finance
elects to repurchase the Trustee's rights to Purchased Receivables to be
Generated pursuant to Section 5.1(b) of the Receivables Purchase Agreement. In
such event, the Trustee shall prepay the Senior Trust Certificates in an amount
equal to the sum of (i) the outstanding principal amount of all Senior Trust
Certificates to be prepaid at the time of prepayment, plus (ii) accrued and
unpaid interest thereon, and Additional Amounts, if any, in respect of all
Senior Trust Certificates, plus (iii) all other amounts payable by the Trustee
in respect of the Senior Trust Certificates; provided, however, that no notice
of prepayment may be given earlier than 60 days prior to the earliest date on
which, but for such prepayment, the Trustee would be obligated to pay such
Additional Amounts if a payment in respect of the Senior Trust Certificates were
then due. Prior to publication of any such notice of prepayment, the Trustee
shall deliver (or cause to be delivered) to the Senior Certificate Holders the
documents that are required to be delivered to the Trustee by Petrobras Finance
pursuant to Section 5.1(b)(iii) of the Receivables Purchase Agreement.

     8.   Notice of Prepayment. Notice of prepayment shall include the
information and be mailed as required in the Trust Deed at least 30 days but not
more than 60 days before the Prepayment Date to each Senior Certificate Holder
whose Senior Trust Certificates are to be prepaid. If the Trustee complies with
the provisions set forth in the Trust Deed, on and after the Prepayment Date,
interest shall cease to accrue on the relevant Series of Senior Trust
Certificates, or, in the case of a mandatory prepayment, the portions of such
Senior Trust Certificates, to be prepaid.

     9.   Additional Prepayment Terms. If a Senior Trust Certificate is prepaid
on or after a Regular Record Date but on or prior to the related Payment Date,
then all amounts in respect of such prepayment shall be paid to the Person in
whose name such Senior Trust Certificate was registered at the close of business
on such Regular Record Date. If any Senior Trust Certificate called for
prepayment shall not be so paid upon surrender for prepayment because of the
failure of the Trustee to comply with the provisions set forth in the Trust
Deed, interest shall be paid on the outstanding principal, from the Prepayment
Date until such principal is paid, and to the extent lawful, on any interest not
paid on such outstanding principal, in each case at the Certificate Rate of
Interest.

                                  Exhibit A-1-7

<PAGE>

     10.  Mandatory Prepayment. Pursuant to the provisions set forth in the
Trust Deed, the Trustee shall prepay, in whole or in part, the Senior Trust
Certificates upon the occurrence and continuation of a Mandatory Prepayment
Event. If less than all of the Senior Trust Certificates are to be prepaid, the
Trustee shall prepay the Senior Trust Certificates pro rata among the Senior
Trust Certificates of all Series. Upon surrender of a Senior Trust Certificate
that is prepaid in part, the Trustee shall issue to such Senior Certificate
Holder (at the expense of the Trustee) a new Senior Trust Certificate equal in
principal amount to the remaining unpaid portion of such Senior Trust
Certificate surrendered.

     11.  Denominations. The Senior Trust Certificates (other than those issued
following a mandatory prepayment in part of the Senior Trust Certificates) shall
be issued in minimum denominations of US$100,000 and integral multiples of
US$1,000 in excess thereof.

     12.  Persons Deemed Owners. The registered Senior Certificate Holder may be
treated by the Registrar as the absolute owner of such Senior Trust Certificate
for all purposes whatsoever.

     13.  Amendment, Supplement, Waiver. Subject to the ultimate sentence of
this paragraph, the Trust Deed and the Senior Trust Certificates may be amended
or supplemented in a Supplemental Trust Deed with the consent of Controlling
Parties representing more than 66 2/3% of the aggregate outstanding principal
amount of the Senior Trust Certificates. Without notice to or the consent of the
Senior Certificate Holders or Controlling Parties, and without a Rating
Affirmation, the Trustee may (having given notice to the Rating Agencies), at
any time and from time to time, execute one or more Supplemental Trust Deeds for
any of the purposes set forth in Section 11.01 of the Trust Deed.
Notwithstanding the foregoing, no such Supplemental Trust Deed shall be executed
without (i) the consent of each Controlling Party of each Series and the consent
of each Senior Certificate Holder of each outstanding Senior Trust Certificate
affected thereby and (ii) a Rating Affirmation, if the effect of such
Supplemental Trust Deed would be any of the events described in Section 11.02 of
the Trust Deed.

     14.  Specified Events, Accumulation Events, Termination Events. Upon the
occurrence of any Specified Event, Accumulation Event or Termination Event, the
Trustee shall have the remedies set forth in Article IX of the Trust Deed.

     15.  Trustee Dealings with Senior Trust Certificates. U.S. Bank, Cayman
Islands Branch, and each other Person acting as Successor trustee or co-trustee
under the Trust Deed, in its individual or any other capacity and its
Affiliates, may deal with the Senior Trust Certificates with the same rights it
would have if it were not the Trustee.

     16.  No Recourse Against Others. A director, Authorized Officer, employee,
agent, manager, interest holder or stockholder, as such, of the Trustee, shall
not have any liability for any obligation of the Trustee under the Senior Trust
Certificates or the Trust Deed or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Senior Certificate Holder, by
accepting a Senior Trust Certificate, waives and releases all such liability.

     The obligations of the Trustee under the Trust Deed and the Senior Trust
Certificates shall be non-recourse to the assets of the Trustee and payable only
out of the Trust Property. The

                                 Exhibit A-1-8

<PAGE>

Trustee has, and each Senior Certificate Holder, by accepting a Senior Trust
Certificate shall be deemed to have, agreed in the Trust Deed that neither the
Trustee in its individual capacity nor its assets (other than the Trust
Property), shall be liable for any of the obligations of the Trustee under the
Trust Deed or the Senior Trust Certificates except as expressly provided in the
Trust Deed.

     17.  Abbreviations. Customary abbreviations may be used in the name of a
Senior Certificate Holder or an assignee, such as: TEN COM (tenants in common),
TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of
survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A
(Uniform Gifts to Minors Act).

     18.  CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Securities Identification Procedures, the Trustee shall
cause CUSIP numbers to be printed on the Senior Trust Certificates as a
convenience to the Senior Certificate Holders. No representation is made as to
the accuracy of such numbers as printed on the Senior Trust Certificates and
reliance may be placed only on the other identification numbers printed hereon.

     19.  Governing Law. This Senior Trust Certificate shall be governed by and
construed in accordance with the law of the Cayman Islands.

                       PF Export Receivables Master Trust
        FLOATING RATE SENIOR TRUST CERTIFICATE, SERIES [__] DUE [______]

     This Senior Trust Certificate is one of a duly authorized issue of Floating
Rate Senior Trust Certificates, Series [__], due [___] of the Trustee issued
under the Trust Deed, to which Trust Deed reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Trustee and the Senior Certificate Holders and of the terms
upon which the Senior Trust Certificates are, and are to be, authenticated and
delivered. The Senior Trust Certificates of this Series are limited in an
aggregate principal amount to U.S.$[_________].

     1.   Payment of Interest, Principal and Additional Amounts.

     (a)  The Trustee of the PF Export Receivables Master Trust (the "Trustee")
promises to pay interest on the aggregate unpaid principal amount of this Senior
Trust Certificate at the Certificate Rate of Interest (as described in Section
1(b) below) until the Final Payment Date and to pay Additional Amounts in
accordance with the Trust Deed. The Trustee shall pay principal of this Senior
Trust Certificate in accordance with the Amortization Schedule attached hereto
and shall pay interest and Additional Amounts, if any, in each case quarterly on
March 1, June 1, September 1 and December 1 of each year (each a "Payment
Date"), or if any such day is not a Business Day, on the next succeeding
Business Day. Payments of interest will commence on [____________]. Payments of
principal will commence on [____________]. The Final Scheduled Principal Payment
Date is [____]. Interest shall accrue on the outstanding principal amount of
each Senior Trust Certificate from and including the date of issuance of such
Senior Trust Certificate to, but excluding the Final Payment Date. The Final
Payment Date shall be either the Final Scheduled Principal Payment Date or such
other date upon which the principal amount of this Series of Senior Trust
Certificates is paid in full. Interest shall be computed on the basis of a
360-day year and actual number of days elapsed. To the extent permitted by
applicable law, any payments due and not punctually paid on or in respect of the
Senior Trust Certificates shall bear interest until paid at the applicable
Certificate Rate of Interest plus [ ]% (the "Default Interest Rate").

     (b)  For purposes of the calculation of the Certificate Rate of Interest
described in Section 1(a) above, the "Certificate Rate of Interest" shall mean
the sum of (i) LIBOR, as calculated in (c) below, which will be calculated on
the second Business Day prior to the commencement of each Quarterly Delivery
Period (each such date a "Determination Date"), plus (ii) [___]%.

     (c)  LIBOR will be determined by the Calculation Agent and reported to the
Trustee on each Determination Date as soon as practicable after 11:00 a.m.
(London time) on the following basis:

          (i)  On each Determination Date, LIBOR will be the offered quotation
     to leading banks for three-month U.S. dollar deposits as quoted by the
     British Banker's Association on Telerate Page 3750 on the Dow Jones Market
     Service (or such other page

                                 Exhibit A-2-5

<PAGE>

     as may replace page 3750 on that service for display of such information
     or, if that service ceases to display such information, such page as
     displays such information on an equivalent service), as reported by
     Bloomberg Financial Commodities News at approximately 11:00 a.m. (London
     time) on the Determination Date in question.

          (ii)  If on any Determination Date, such offered quotation does not
     appear on Telerate Page 3750 or such alternative service, LIBOR shall be
     determined on the basis of the rates at which three-month deposits in U.S.
     dollars are offered by four major banks in the London interbank market
     (which may include the Calculation Agent) selected by the Calculation Agent
     (the "Reference Banks"), at approximately 11:00 a.m. (London time) on such
     Determination Date to prime banks in the London interbank market in a
     principal amount equal to not less than $1,000,000. The Calculation Agent
     will request the principal London office of each of the Reference Banks to
     provide a quotation of its rate. If at least two such quotations are
     provided, the Certificate Rate of Interest will be the arithmetic mean of
     the quotations rounded to four decimal places, as determined by the
     Calculation Agent. If fewer than two quotations are provided, the
     Certificate Rate of Interest will be the arithmetic mean of the rates
     quoted by at least two major banks in New York City (which may include the
     New York office of the Calculation Agent), selected by the Calculation
     Agent, at approximately 11:00 a.m., New York City time, on such
     Determination Date for three-month loans in U.S. dollars to leading
     European banks in a principal amount equal to not less than $1,000,000;
     provided that if fewer than two banks selected as aforesaid by the
     Calculation Agent are quoting rates as mentioned above, LIBOR shall be the
     rate in effect for the previous Quarterly Delivery Period.

     (d)  Except as provided below, the Trustee shall make all payments of
amounts due on the Senior Trust Certificates, without withholding or deduction
of any present or future taxes, duties, levies, imposts, assessments or other
governmental charges (including penalties, interest and other liabilities
related thereto) of any nature imposed by Brazil, the Cayman Islands, the United
States or any jurisdiction from or through which payment is made in respect of
the Senior Trust Certificates, or any political subdivision of any such
jurisdiction (collectively, "Taxes"). If any such Taxes are so imposed, the
Trustee shall pay the Senior Certificate Holders such additional amounts as are
necessary to ensure that they receive the same amount as they would have
received had no such withholding or deduction been imposed (such amounts,
"Additional Amounts"). The Trustee shall not, however, pay any Excluded
Additional Amounts, as defined and set forth in Section 2.02(e) of the Trust
Deed.

     (e)  The Trustee shall pay any stamp, administrative, excise or property
Taxes arising in a taxing jurisdiction in connection with the Senior Trust
Certificates and shall indemnify the Senior Certificate Holders for any such
stamp, administrative, excise or property Taxes paid by Senior Certificate
Holders.

     2.   Method of Payment. All payments in respect of the Senior Trust
Certificates shall be made at the Specified Office of the Paying Agent in The
City of New York and, subject to any fiscal or other laws and regulations
applicable thereto, at the specified offices of any other Paying Agent appointed
by the Trustee for such purpose. Payment in respect of principal and interest on
any Payment Date with respect to any Senior Trust Certificate shall be made to
the Person in whose name such Senior Trust Certificate is registered on the
Regular Record Date

                                 Exhibit A-2-6

<PAGE>

immediately preceding the applicable Payment Date. Payments with respect to any
Senior Trust Certificate shall be made by a dollar check drawn on a bank in The
City of New York and mailed to such Person's address registered with the Trustee
or, in the case of a registered holder of at least $1,000,000 principal amount
of Senior Trust Certificates, by wire transfer to a dollar account maintained by
the payee with a bank in the United States so long as the registered Senior
Certificate Holder so elects by giving written notice to such effect designating
such account which is received by the Trustee or a Paying Agent no later than
the Regular Record Date immediately preceding such Payment Date. Unless such
designation is revoked, any such designation made by such Senior Certificate
Holder with respect to such Senior Trust Certificates shall remain in effect
with respect to any future payments with respect to such Senior Trust
Certificate payable to such Senior Certificate Holder. Only the final
installment of principal on the Senior Trust Certificates, whether on the Final
Scheduled Principal Payment Date or otherwise, shall be payable upon surrender
of any Senior Trust Certificate at the Specified Office of the Trustee or at the
specified offices of any Paying Agent.

     3.   Paying Agent, Transfer Agent and Registrar. The Trustee shall cause to
be maintained an office or agency in The City of New York where the Senior Trust
Certificates may be presented for registration of transfer or for exchange. The
Trustee shall cause to be maintained an office or agency where the Senior Trust
Certificates may be presented and surrendered for payment. The Registrar shall
keep a register ("Register") of Senior Trust Certificates and of their transfer
and exchange. The Trustee may, at its discretion, appoint one or more agents
(each, a "Paying Agent" and, collectively, the "Paying Agents") for the payment
of any and all amounts due and payable by the Trustee from time to time in
respect of the Senior Trust Certificates, and the Trustee may, at its
discretion, appoint one or more agents (each, a "Transfer Agent" and,
collectively, the "Transfer Agents") for the transfer and exchange of the Senior
Trust Certificates, at such place or places as the Trustee may determine,
provided, however, that there shall at all times be a Paying Agent, Transfer
Agent and Registrar in the Borough of Manhattan, The City of New York. So long
as the Senior Trust Certificates are listed on the Luxembourg Stock Exchange and
the rules of the Luxembourg Stock Exchange so require, there shall be maintained
a Paying Agent and a Transfer Agent in Luxembourg (the "Luxembourg Paying
Agent"). [Initially, Citibank, N.A. shall act as the Paying Agent, Registrar and
Transfer Agent and Kredietbank S.A. Luxembourgeoise shall act as the Luxembourg
Paying Agent and Luxembourg Listing Agent.]

     4.   Additional Senior Trust Certificates. Subject to the requirements set
forth in the Trust Deed, the Trustee shall be permitted to issue additional
senior trust certificates by Supplemental Trust Deed after the date of the
issuance of this Senior Trust Certificate.

     [5.  Guarantees. Payment of principal and interest is guaranteed by
[_______] as described in the Supplemental Trust Deed relating to this Series of
Senior Trust Certificates.]

     6.   Optional Prepayment. (a) Any Series of Senior Trust Certificates may
be subject to optional prepayment in whole but not in part in the event that
Petrobras Finance elects to repurchase all or a portion of the Trustee's rights
to Purchased Receivables to be Generated pursuant to Section 5.1(a) of the
Receivables Purchase Agreement. In such event, the Trustee shall prepay the
Senior Trust Certificates of such Series in an amount equal to the sum of (i)
the outstanding principal amount of the Senior Trust Certificates to be prepaid
at the time of

                                 Exhibit A-2-7

<PAGE>

prepayment, plus (ii) accrued and unpaid interest thereon, and Additional
Amounts, if any, in respect of such Series of Senior Trust Certificates, to the
Prepayment Date, plus the Break Amount as described in Section 6(b) below, if
payment is not made on a Payment Date plus (iv) all other amounts payable by the
Trustee in respect of such Senior Trust Certificates.

      (b) For purposes of the calculation of the Break Amount referred to in
Section 6(a) above, the "Break Amount" shall mean, as of any date of payment,
redemption or acceleration for any Senior Trust Certificate (the "Applicable
Date"), an amount determined by the Calculation Agent on the date that is two
LIBOR Business Days prior to the Applicable Date pursuant to the formula set
forth below:

      The Break Amount shall be calculated as follows:
               Break Amount = Z-Y
               Where:
                           X =     with respect to any applicable interest
                                   period, the sum of (i) the amount of the
                                   outstanding principal amount for such Series
                                   of Senior Trust Certificate as of the first
                                   day of the then applicable interest period
                                   plus (ii) interest payable thereon during
                                   such entire interest period at then
                                   effective three-month LIBOR.

                           Y =     X discounted to present value from the
                                   last day of the then applicable interest
                                   period to the Applicable Date, using then
                                   effective three-month LIBOR as the discount
                                   rate.

                           Z =     X discounted to present value from the
                                    last day of the then applicable interest
                                    period to the Applicable Date using a rate
                                    equal to the applicable London interbank
                                    offered rate for a period commencing on the
                                    Applicable Date and ending on the last day
                                    of the applicable interest period,
                                    determined by the Calculation Agent as of
                                    two LIBOR Business Days prior to the
                                    Applicable Date as the discount rate.

            No Break Amount will be payable (x) if the Break Amount, as
      calculated pursuant to the formula set forth above, is equal to or less
      than zero or (y) on, or in respect of, any Applicable Date that is a
      Payment Date.

      7.    Tax Prepayment. The Trustee shall prepay all of the Senior Trust
Certificates, in whole but not in part, in the event that Petrobras Finance
elects to repurchase the Trustee's rights to Purchased Receivables to be
Generated pursuant to Section 5.1(b) of the Receivables Purchase Agreement. In
such event, the Trustee shall prepay the Senior Trust Certificates in an amount
equal to the sum of (i) the outstanding principal amount of all Senior Trust
Certificates to be prepaid at the time of prepayment, plus (ii) accrued and
unpaid interest thereon, and Additional Amounts, if any, in respect of all
Senior Trust Certificates plus (iii) the Break Amount plus (iv) all other
amounts payable by the Trustee in respect of the Senior Trust Certificates;
provided, however, that no notice of prepayment may be given earlier than 60
days prior to the earliest date on which, but for such prepayment, the Trustee
would be obligated to pay such Additional Amounts if a payment in respect of the
Senior Trust Certificates were then due. Prior to

                                 Exhibit A-2-8

<PAGE>

publication of any such notice of prepayment, the Trustee shall deliver (or
cause to be delivered) to the Senior Certificate Holders the documents that are
required to be delivered to the Trustee by Petrobras Finance pursuant to Section
5.1(b)(iii) of the Receivables Purchase Agreement.

      8.    Notice of Prepayment. Notice of prepayment shall include the
information and be mailed as required in the Trust Deed at least 30 days but not
more than 60 days before the Prepayment Date to each Senior Certificate Holder
whose Senior Trust Certificates are to be prepaid. If the Trustee complies with
the provisions set forth in the Trust Deed, on and after the Prepayment Date,
interest shall cease to accrue on the relevant Series of Senior Trust
Certificates, or, in the case of a mandatory prepayment, the portions of such
Senior Trust Certificates, to be prepaid.

      9.    Additional Prepayment Terms. If a Senior Trust Certificate is
prepaid on or after a Regular Record Date but on or prior to the related Payment
Date, then all amounts in respect of such prepayment shall be paid to the Person
in whose name such Senior Trust Certificate was registered at the close of
business on such Regular Record Date. If any Senior Trust Certificate called for
prepayment shall not be so paid upon surrender for prepayment because of the
failure of the Trustee to comply with the provisions set forth in the Trust
Deed, interest shall be paid on the outstanding principal, from the Prepayment
Date until such principal is paid, and to the extent lawful, on any interest not
paid on such outstanding principal, in each case at the Certificate Rate of
Interest.

      10.   Mandatory Prepayment. Pursuant to the provisions set forth in the
Trust Deed, the Trustee shall prepay, in whole or in part, the Senior Trust
Certificates upon the occurrence and continuation of a Mandatory Prepayment
Event. If less than all of the Senior Trust Certificates are to be prepaid, the
Trustee shall prepay the Senior Trust Certificates pro rata among the Senior
Trust Certificates of all Series. Upon surrender of a Senior Trust Certificate
that is prepaid in part, the Trustee shall issue to such Senior Certificate
Holder (at the expense of the Trustee) a new Senior Trust Certificate equal in
principal amount to the remaining unpaid portion of such Senior Trust
Certificate surrendered.

      11.   Denominations. The Senior Trust Certificates (other than those
issued following a mandatory prepayment in part of the Senior Trust
Certificates) shall be issued in minimum denominations of US$100,000 and
integral multiples of US$1,000 in excess thereof.

      12.   Persons Deemed Owners. The registered Senior Certificate Holder may
be treated by the Registrar as the absolute owner of such Senior Trust
Certificate for all purposes whatsoever.

      13.   Amendment, Supplement, Waiver. Subject to the ultimate sentence of
this paragraph, the Trust Deed and the Senior Trust Certificates may be amended
or supplemented in a Supplemental Trust Deed with the consent of Controlling
Parties representing more than 66 2/3% of the aggregate outstanding principal
amount of the Senior Trust Certificates. Without notice to or the consent of the
Senior Certificate Holders or Controlling Parties, and without a Rating
Affirmation, the Trustee may (having given notice to the Rating Agencies), at
any time and from time to time, execute one or more Supplemental Trust Deeds for
any of the purposes set forth in Section 11.01 of the Trust Deed.
Notwithstanding the foregoing, no such Supplemental Trust

                                 Exhibit A-2-9

<PAGE>

Deed shall be executed without (i) the consent of each Controlling Party of each
Series and the consent of each Senior Certificate Holder of each outstanding
Senior Trust Certificate affected thereby and (ii) a Rating Affirmation, if the
effect of such Supplemental Trust Deed would be any of the events described in
Section 11.02 of the Trust Deed.

      14.   Specified Events, Accumulation Events, Termination Events. Upon the
occurrence of any Specified Event, Accumulation Event or Termination Event, the
Trustee shall have the remedies set forth in Article IX of the Trust Deed.

      15.   Trustee Dealings with Senior Trust Certificates. U.S. Bank, Cayman
Islands Branch, and each other Person acting as Successor trustee or co-trustee
under the Trust Deed, in its individual or any other capacity and its
Affiliates, may deal with the Senior Trust Certificates with the same rights it
would have if it were not the Trustee.

      16.   No Recourse Against Others. A director, Authorized Officer,
employee, agent, manager, interest holder or stockholder, as such, of the
Trustee, shall not have any liability for any obligation of the Trustee under
the Senior Trust Certificates or the Trust Deed or for any claim based on, in
respect of or by reason of such obligations or their creation. Each Senior
Certificate Holder, by accepting a Senior Trust Certificate, waives and releases
all such liability.

      The obligations of the Trustee under the Trust Deed and the Senior Trust
Certificates shall be non-recourse to the assets of the Trustee and payable only
out of the Trust Property. The Trustee has, and each Senior Certificate Holder,
by accepting a Senior Trust Certificate shall be deemed to have, agreed in the
Trust Deed that neither the Trustee in its individual capacity nor its assets
(other than the Trust Property), shall be liable for any of the obligations of
the Trustee under the Trust Deed or the Senior Trust Certificates except as
expressly provided in the Trust Deed.

      17.   Abbreviations. Customary abbreviations may be used in the name of a
Senior Certificate Holder or an assignee, such as: TEN COM (tenants in common),
TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of
survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A
(Uniform Gifts to Minors Act).

      18.   CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Securities Identification Procedures, the Trustee shall
cause CUSIP numbers to be printed on the Senior Trust Certificates as a
convenience to the Senior Certificate Holders. No representation is made as to
the accuracy of such numbers as printed on the Senior Trust Certificates and
reliance may be placed only on the other identification numbers printed hereon.

      19.   Governing Law. This Senior Trust Certificate shall be governed by
and construed in accordance with the law of the Cayman Islands.

(London time) on the following basis:

                                  Exhibit E-2-4

<PAGE>

          (i)  On each Determination Date, LIBOR will be the offered quotation
     to leading banks for three-month U.S. dollar deposits (or, from and after
     the first Payment Date following an Acceleration Event, one-month U.S.
     Dollar deposits) as quoted by the British Banker's Association on Telerate
     Page 3750 on the Dow Jones Market Service (or such other page as may
     replace page 3750 on that service for display of such information or, if
     that service ceases to display such information, such page as displays such
     information on an equivalent service), as reported by Bloomberg Financial
     Commodities News at approximately 11:00 a.m. (London time) on the
     Determination Date in question.

          (ii) If on any Determination Date, such offered quotation does not
     appear on Telerate Page 3750 or such alternative service, LIBOR shall be
     determined on the basis of the rates at which three-month deposits in U.S.
     dollars (or, from and after the first Payment Date following an
     Acceleration Event, one-month U.S. Dollar deposits) are offered by four
     major banks in the London interbank market (which may include the
     Calculation Agent) selected by the Calculation Agent (the "Reference
     Banks"), at approximately 11:00 a.m. (London time) on such Determination
     Date to prime banks in the London interbank market in a principal amount
     equal to not less than $1,000,000. The Calculation Agent will request the
     principal London office of each of the Reference Banks to provide a
     quotation of its rate. If at least two such quotations are provided, the
     Series [ ] Senior Trust Certificate Rate will be the arithmetic mean of the
     quotations rounded to four decimal places, as determined by the Calculation
     Agent. If fewer than two quotations are provided, the Series [ ] Senior
     Trust Certificate Rate will be the arithmetic mean of the rates quoted by
     at least two major banks in New York City (which may include the New York
     office of the Calculation Agent), selected by the Calculation Agent, at
     approximately 11:00 a.m., New York City time, on such Determination Date
     for three-month loans (or, from and after the first Payment Date following
     an Acceleration Event, one-month loans) in U.S. dollars to leading European
     banks in a principal amount equal to not less than $1,000,000; provided
     that if fewer than two banks selected as aforesaid by the Calculation Agent
     are quoting rates as mentioned above, LIBOR shall be the rate in effect for
     the previous Quarterly Delivery Period.

     (c)  The Calculation Agent, in accordance with Section 2.4(b), on each
Determination Date, shall determine the Series [ ] Senior Trust Certificate Rate
and calculate the amount of interest payable in respect of the relevant
Quarterly Delivery Period (or Monthly Interest Period, as applicable) in respect
of the Series [ ] Senior Trust Certificates (each a "Payment Amount"). The
Payment Amount with respect to the Series [ ] Senior Trust Certificates shall be
calculated by multiplying the Series [ ] Senior Trust Certificate Rate by the
outstanding principal amount of the Series [ ] Senior Trust Certificates,
dividing by 360 and multiplying the resulting figure by the actual number of
days in the Quarterly Delivery Period (or Monthly Interest Period, as
applicable) concerned and rounding the resultant figure to the nearest $0.01
($0.005 being rounded upwards). The determination of the Series [ ] Senior Trust
Certificate Rate and the Payment Amount by the Calculation Agent shall (in the
absence of manifest error) be final and binding on all parties.

     (d)  The Trustee will cause the Series [ ] Senior Trust Certificate Rate,
the Payment Amount and the Payment Date for each Quarterly Delivery Period (or
Monthly Interest Period,

                                  Exhibit E-2-5

<PAGE>

as applicable) to be notified to the Registrar no later than two Business Days
after each Determination Date.

     (e)  All certificates, communications, opinions, determinations,
calculations, quotations and decisions given, expressed, made or obtained for
the purpose of the provisions of this Section 2.4 by the Calculation Agent shall
(in the absence of willful misconduct, bad faith or manifest error) be binding
on the Trustee and all of the Series [ ] Senior Certificate Holders, and no
liability shall attach to the Calculation Agent (or the Trustee, in the event
the Calculation Agent fails to calculate the Series [ ] Senior Trust Certificate
Rate) in connection with the exercise or non-exercise by it of its powers,
duties and discretions.

     SECTION 2.5. Prepayment. In the case of any full or partial prepayment
pursuant to Article III of the Trust Deed, the prepayment price shall be the
price set forth in Article III of the Trust Deed.

     SECTION 2.6. Restrictions on Transfer and Exchange of Initial Senior Trust
Certificates. All Series [ ] Senior Trust Certificates issued hereunder and all
Senior Trust Certificates issued upon registration of transfer of, or in
exchange for, the Series [ ] Senior Trust Certificates issued hereunder, shall
be subject to the restrictions on transfer provided in the Trust Deed and the
legends set forth on such Senior Trust Certificates.

     SECTION 2.7. References to Interest and Principal. For the avoidance of
doubt, any reference in this Series [ ] Supplemental Trust Deed or any Series
[ ] Senior Trust Certificates to the payment of principal and interest in
connection with the Series [ ] Senior Trust Certificates shall be construed to
mean payments by means of distributions out of the Trust Property.

     SECTION 3.3. Source of Payments Limited; Rights and Liabilities of the
Trustee. All Series [ ] Senior Trust Certificates issued hereunder shall be
subject to the limitations on liability and limitations on recourse provided in
the Trust Deed.

     SECTION 3.4. Counterparts. This Series [ ] Supplemental Trust Deed may be

deemed to be an original, but all such counterparts shall together constitute
but one of the same instrument.

     SECTION 2.4. Series [ ] Junior Trust Certificate Rate Calculation.

     (a)  For purposes of the calculation of the Series [ ] Junior Trust
Certificate Rate described in Section 2.3 hereof, the "Series [ ] Junior Trust
Certificate Rate" shall mean the sum of (i) LIBOR, as calculated in (b) below,
which will be calculated on the second Business Day prior to the commencement of
each Quarterly Delivery Period (each such date a "Determination Date"), plus
(ii) the Applicable Margin.

     (b)  LIBOR will be determined by the Calculation Agent and reported to the
Trustee on each Determination Date as soon as practicable after 11:00 a.m.
(London time) on the following basis:

          (i) On each Determination Date, LIBOR will be the offered quotation to
     leading banks for three-month U.S. dollar deposits as quoted by the British
     Banker's Association on Telerate Page 3750 on the Dow Jones Market Service
     (or such other page as may replace page 3750 on that service for display of
     such information or, if that service ceases to display such information,
     such page as displays such information on an equivalent service), as
     reported by Bloomberg Financial Commodities News at approximately 11:00
     a.m. (London time) on the Determination Date in question.

                  (ii) If on any Determination Date, such offered quotation does
     not appear on Telerate Page 3750 or such alternative service, LIBOR shall
     be determined on the basis of the rates at which three-month deposits in
     U.S. dollars are offered by four major banks in the London interbank market
     (which may include the Calculation Agent) selected by the Calculation Agent
     (the "Reference Banks"), at approximately 11:00 a.m. (London time) on such
     Determination Date to prime banks in the London interbank market in a
     principal amount equal to not less than $1,000,000. The Calculation Agent
     will request

                                 Exhibit E-4-4

<PAGE>

     the principal London office of each of the Reference Banks to provide a
     quotation of its rate. If at least two such quotations are provided, the
     Series [ ] Junior Trust Certificate Rate will be the arithmetic mean of the
     quotations rounded to four decimal places, as determined by the Calculation
     Agent. If fewer than two quotations are provided, the Series [ ] Junior
     Trust Certificate Rate will be the arithmetic mean of the rates quoted by
     at least two major banks in New York City (which may include the New York
     office of the Calculation Agent), selected by the Calculation Agent, at
     approximately 11:00 a.m., New York City time, on such Determination Date
     for three-month loans in U.S. dollars to leading European banks in a
     principal amount equal to not less than $1,000,000; provided that if fewer
     than two banks selected as aforesaid by the Calculation Agent are quoting
     rates as mentioned above, LIBOR shall be the rate in effect for the
     previous Quarterly Delivery Period.

     (c)  The Calculation Agent, in accordance with Section 2.4(b), on each
Determination Date, shall determine the Series [ ] Junior Trust Certificate Rate
and calculate the amount of interest payable in respect of the relevant
Quarterly Delivery Period in respect of the Series [ ] Junior Trust Certificates
(each a "Payment Amount"). The Payment Amount with respect to the Series [ ]
Junior Trust Certificates shall be calculated by multiplying the Series [ ]
Junior Trust Certificate Rate by the outstanding principal amount of the Series
[ ] Junior Trust Certificates, dividing by 360 and multiplying the resulting
figure by the actual number of days in the Quarterly Delivery Period concerned
and rounding the resultant figure to the nearest $0.01 ($0.005 being rounded
upwards). The determination of the Series [ ] Junior Trust Certificate Rate and
the Payment Amount by the Calculation Agent shall (in the absence of manifest
error) be final and binding on all parties.

     (d)  The Trustee will cause the Series [ ] Junior Trust Certificate Rate,
the Payment Amount and the Payment Date for each Quarterly Delivery Period to be
notified to the Registrar no later than two Business Days after each
Determination Date.

     (e)  All certificates, communications, opinions, determinations,
calculations, quotations and decisions given, expressed, made or obtained for
the purpose of the provisions of this Section 2.4 by the Calculation Agent shall
(in the absence of willful misconduct, bad faith or manifest error) be binding
on the Trustee and all of the Series [ ] Junior Certificate Holders, and no
liability shall attach to the Calculation Agent (or the Trustee, in the event
the Calculation Agent fails to calculate the Series [ ] Junior Trust Certificate
Rate) in connection with the exercise or non-exercise by it of its powers,
duties and discretions.

     SECTION 2.5. Prepayment. In the case of any full or partial prepayment
pursuant to Article III of the Trust Deed, the prepayment price shall be the
price set forth in Article III of the Trust Deed.

     SECTION 2.6. Restrictions on Transfer and Exchange of Initial Junior Trust
Certificates. All Series [ ] Junior Trust Certificates issued hereunder and all
Junior Trust Certificates issued upon registration of transfer of, or in
exchange for, the Series [ ] Junior Trust Certificates issued hereunder, shall
be subject to the restrictions on transfer provided in the Trust Deed and the
legends set forth on such Junior Trust Certificates.

     SECTION 2.7. References to Interest and Principal. For the avoidance of
doubt, any reference in this Series [ ] Junior Supplemental Trust Deed to the
payment of principal and interest in connection with the Series [ ] Junior Trust
Certificates shall be construed to mean payments by means of distributions out
of the Trust Property.
