                                 LOAN AGREEMENT

      THIS LOAN AGREEMENT dated as of April 30, 2002 is among USEB AIRCRAFT
LIMITED, a limited liability company duly incorporated and validly existing
under the laws of the Cayman Islands (the "INITIAL BORROWER PARTY"); BARCLAYS
BANK PLC, a public limited company incorporated under the laws of England and
Wales, as initial lender (the "INITIAL LENDER" and, together with its and any
subsequent successors, permitted assigns and permitted transferees in accordance
with the terms hereof, the "LENDERS"); BARCLAYS BANK PLC, a public limited
company incorporated under the laws of England and Wales, as facility agent for
the Lenders (collectively with any permitted assignee(s), transferee(s) or
successor(s) and in such capacity the "FACILITY AGENT"); WELLS FARGO BANK
NORTHWEST, N.A., not in its individual capacity, but solely as security trustee
(the "SECURITY TRUSTEE"); and EXPORT-IMPORT BANK OF THE UNITED STATES, an agency
of the United States of America ("EX-IM BANK").

                                   WITNESSETH:

      WHEREAS, the Initial Borrower has requested the Initial Lender to
establish a credit facility (the "CREDIT") in favor of the Borrowers in the
principal amount of U.S. $396,822,827 so that the Borrowers may finance or
refinance, as the case may be, (i) up to 85% of the costs for the purchase in
the United States, and export of each Aircraft to the country in which the
initial operator of the Aircraft is based (as approved by Ex-Im Bank) and (ii)
100% of the related Ex-Im Bank Exposure Fees;

      WHEREAS, the Facility Agent will serve as facility agent for the benefit,
and on behalf, of each of the Lenders (other than Ex-Im Bank) in connection with
the Credit, this Agreement and the other Operative Documents;

      WHEREAS, prior to or concurrently with the utilization of any portion of
the Credit with respect to an Aircraft, such Aircraft shall be leased by the
relevant Lessor to the relevant Lessee pursuant to the Lease for such Aircraft
and subleased by such Lessee to either (i) a Sublessee pursuant to a Sublease
and sub-subleased by the Sublessee to the Initial Operating Lessee pursuant to
the Initial Operating Lease applicable to such Aircraft, or (ii) the Initial
Operating Lessee pursuant to the Initial Operating Lease applicable to such
Aircraft, in either case, as contemplated under the Participation Agreement;

      WHEREAS, the obligations of the Borrowers hereunder shall be secured by
the Lien of the Security Documents with respect to, inter alia, each Aircraft
and each Lease, the Lien of each Operating Lessor Security Assignment with
respect to any Quiet Enjoyment Operating Lease, any Assignment of Insurances and
any Operating Lease Credit Document, the Lien of each Lessor Share Pledge
Agreement and the Lien of each Lessee Share Pledge Agreement with respect to all
of the issued and outstanding shares or capital stock, as the case may be, of
each Borrower and each Lessee, respectively;

      WHEREAS, subject to the terms of the Operative Documents, Ex-Im Bank is
prepared to issue to the Facility Agent, on behalf of the Lenders, its guarantee
of repayment of

                                                                [Loan Agreement]

disbursements made under the Credit together with certain interest thereon, all
as set forth in the Ex-Im Bank Guarantee; and

      WHEREAS, the establishment of the Credit will facilitate exports and
imports between the United States of America and each of Brazil, Turkey and any
other country in which the Initial Operating Lessee of an Aircraft is based.

      NOW, THEREFORE, in consideration of the foregoing and other valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto hereby agree as follows:

      SECTION 1. Definitions; Amount of the Credit.

      1.1 Definitions. Unless the context otherwise requires, (a) capitalized
terms used herein and not otherwise defined herein shall have the meanings set
forth in Part I of Appendix A hereto for all purposes of this Agreement and (b)
the rules of construction and interpretation for this Agreement shall be set
forth in Part II of Appendix A hereto,

      1.2 Amount of the Credit. Subject to the terms and conditions set forth in
this Agreement and the Participation Agreement, the Initial Lender hereby
establishes the Credit in favor of the Borrowers in the principal amount of
U.S.$396,822,827, and the Lenders agree, upon the terms and conditions
hereinafter set forth, to make Disbursements in an aggregate amount with respect
to each Aircraft equal to the Ex-Im Bank Eligible Amount in relation to such
Aircraft, provided that in no event shall the aggregate of all Disbursements
exceed the Ex-Im Bank Commitment.

      SECTION 2. Commitments.

      2.1 Loan. Subject to the terms and conditions set forth below, on the
Borrowing Date for a Loan, the Initial Lender or, if at the relevant time the
Initial Lender is not the only Lender, the Lenders shall make Disbursements to
the Initial Borrower of such Loan in the aggregate principal amount up to but
not exceeding the amount of each such Lender's Designated Percentage of the
Credit (each a "COMMITMENT") (the amount of the Disbursement made by the Lenders
in respect of an Aircraft on a Borrowing Date shall be referred to herein as a
"LOAN" and the aggregate amount of such Loans shall be referred to herein as the
"LOANS"). Each Loan shall be made only during the Availability Period.

      2.2 Borrowings.

            (a) Subject to Section 4.3, GFC (acting on behalf of the relevant
Initial Borrower) shall give the Facility Agent (who shall promptly notify each
Lender thereof) and Ex-Im Bank notice in the form of Exhibit A hereto of each
borrowing by such Borrower hereunder (each, a "NOTICE OF BORROWING").

            (b) Following receipt of a Notice of Borrowing from GFC (on behalf
of the relevant Initial Borrower), the Facility Agent shall determine the
Floating Rate (for the initial Interest Period) or the Fixed Rate, as the case
may be, as requested in such Notice of Borrowing, to be applicable to the
relevant Loan in accordance with the respective definition thereof,

                                       2
<PAGE>

                                                                [Loan Agreement]

provided that, in the case of a determination of the Fixed Rate, if the Facility
Agent is unable to agree the rate with GFC (as provided in the definition of
Fixed Rate) prior to the Borrowing Date for such Loan then such Loan shall
initially bear interest at the Floating Rate.

          (c) Upon determination of the Applicable Rate on or prior to the
relevant Borrowing Date for a Loan, the Facility Agent shall calculate the Basic
Rent and Termination Value schedules in respect of the relevant Aircraft on the
basis of such Applicable Rate for such Loan, and shall submit such calculated
schedules to GFC and Ex-Im Bank for approval. On the relevant Borrowing Date,
each Lender shall, subject to Section 2.1 and subject further to the
satisfaction of the conditions precedent set forth in Section 7(a), make
available to the Facility Agent its Designated Percentage of the amount of the
Loan to be made, at an account to be designated by the Facility Agent with
Barclays Bank PLC, New York, New York, or to such other account in New York, New
York as the Facility Agent may specify for such purpose, in Dollars and
immediately available funds, for account of the relevant Borrower. The aggregate
amount so received by the Facility Agent shall, subject to the terms and
conditions of this Agreement and the other Operative Documents, be made
available to the Initial Borrower of the relevant Loan by depositing the same,
in immediately available funds, in the Designated Account. Without prejudice to
the last sentence of Section 2.1, (a) the obligations of the Lenders hereunder
are the several obligations of each Lender and not joint and several
obligations, and (b) no Lender shall have any liability to any Borrower, any
Guarantor or any Lessee for the failure of any other Lender to advance its
portion of any Loan hereunder. The Facility Agent shall have no such liability.
The rights of the Lenders hereunder and under the other Operative Documents are
several. Any amount at any time owing by a Borrower to any party hereto under
this Agreement or any other Operative Document shall be a separate and
independent debt from the amount owing to any other party hereto.

      2.3 Termination of Commitments. GFC may, on behalf of the Borrower Parties
(and the Borrowing Parties may not otherwise), terminate the Credit (or the
entire or any part of the unutilized portion thereof) by giving notice thereof
(which notice shall be irrevocable) to the Facility Agent; provided that: (i)
GFC (on behalf of the Borrower Parties) shall give notice of such termination as
provided in Section 4.3 and (ii) the Credit (or the relevant unutilized portion
thereof) once terminated may not be reinstated. In the event of a cancellation
of all or part of the Ex-Im Bank Commitment by Ex-Im Bank pursuant to Section 25
of the Participation Agreement, all or a corresponding portion, as the case may
be, of the Credit (and each Lender's Commitment) shall ipso facto be cancelled
for the purposes of this Agreement and each other Operative Document and each
Borrower shall pay to the Facility Agent (for the account of itself and the
Lenders) on demand all fees, expenses and other amounts (including, but not
limited to, any Transaction Costs), then due and owing by it to or for the
benefit of the Facility Agent or any Lender under this Agreement or any other
Operative Document.

      2.4 Prepayments.

          (a) In the event of the Lessee under a Lease becoming obliged pursuant
to any provision of such Lease to pay the Termination Value with respect to the
Aircraft the subject of such Lease (whether as a result of (i) the termination
of the leasing of such Aircraft under such Lease for any reason, (ii) the
Borrower's having made a demand on the Lessee under such Lease pursuant to
Section 14 or 15 of such Lease following the occurrence of a Lease Event of
Default

                                       3

                                                                [Loan Agreement]

or a Mandatory Prepayment Event, as the case may be, or (iii) or otherwise), the
relevant Borrower shall prepay the Loan for such Aircraft in full (together with
accrued interest thereon and all other amounts then due and owing by such
Borrower hereunder and under the other Operative Documents in respect of such
Loan (including, without limitation, amounts payable under the Borrower
Indemnity Agreement)) on the date on which such Lessee is obligated to pay such
Termination Value with respect to such Aircraft under such Lease.

            (b) If GFC has become obliged to pay any Lender any amount pursuant
to Clause 3 (Taxes) or Clause 7 (Increased Costs) of the Borrower Indemnity
Agreement in relation to any Loan, then the Borrower of such Loan may, provided
GFC (on behalf of such Borrower) has given to the Facility Agent and Ex-Im Bank
written notice of such prepayment as provided in Section 4.3, prepay such
Lender's share of such Loan, and upon giving such notice such Lender's
Commitment shall be cancelled.

            (c) Any notice of prepayment given by GFC (on behalf of a Borrower)
pursuant to Section 2.4(b) shall be irrevocable, shall specify the date upon
which such prepayment is to be made and the amount of such prepayment and shall
oblige such Borrower to make such prepayment on such date.

            (d) Any prepayment pursuant to Section 2.4(a) or (b) shall satisfy
pro tanto the relevant Borrower's obligations in relation to the applicable Loan
and Note (or portion thereof, in the case of any partial prepayment pursuant to
Section 2.4(b)).

            (e) Any partial prepayment pursuant to Section 2.4(b) shall be
applied in reduction of the remaining principal installments of the applicable
Loan and Note pro rata.

            (f) Any amount prepaid under this Agreement may not be reborrowed.

            (g) Neither GFC nor any Borrower may voluntarily prepay any of such
Borrower's Loans except in accordance with the express terms of this Section
2.4.

      SECTION 3. Payments of Principal and Interest; Promissory Note.

      3.1 Repayment of Loan. (a) Each Borrower shall pay to the Facility Agent
for account of the Lenders the entire aggregate outstanding principal amount of
each of its Loans in installments, payable on the Loan Payment Dates applicable
to such Loan in the principal amount set forth in Schedule I to the Note
relating to such Loan; provided, that the principal installment payable on the
Final Maturity Date for any such Loan shall in all cases be in an amount equal
to the entire principal amount of such Loan outstanding on such date, and such
principal installment shall be paid together with all accrued and unpaid
interest and all other amounts then owing hereunder and under the other
Operative Documents with respect to such Loan.

            (b) Notwithstanding Section 3.1 (a), if Ex-Im Bank shall have made a
claim payment under the Ex-Im Bank Guarantee with respect to a demand under any
Note, subject always to Ex-Im Bank's right to accelerate the related Loan under
Section 10.2, the relevant Borrower shall pay to Ex-Im Bank the remaining entire
aggregate outstanding principal amount

                                       4
<PAGE>

                                                                [Loan Agreement]

of such Loan in installments as provided in Section 3.1 (a), or in quarterly or
semi-annual installments as Ex-Im Bank may elect by notice in writing to GFC and
such Borrower.

      3.2 Interest; Ex-Im Bank's Overdue Amounts.

            (a) Interest.

                (i) Each Borrower shall pay to the Facility Agent for account of
      the Lenders (other than Ex-Im Bank) interest on the unpaid principal
      amount of each of its Loans for the period from and including the
      Borrowing Date of each such Loan but excluding the date such Loan shall be
      paid in full, at a rate per annum for each Interest Period relating
      thereto equal to the Applicable Rate for such Loan and for such Interest
      Period.

                (ii) Each Borrower will procure that GFC pays to the Facility
      Agent for account of the Lenders interest at the applicable Post-Default
      Rate on any principal of any of its Loans and on any interest thereon and
      any other amount payable by such Borrower hereunder that shall not be paid
      in full when due (whether at stated maturity, by acceleration or
      otherwise), for the period from and including the due date thereof to but
      excluding the date the same is paid in full in accordance with the
      provisions of the Borrower Indemnity Agreement.

                (iii) Accrued interest on each Loan shall be payable on each
      Loan Payment Date applicable thereto and upon the payment or prepayment
      thereof (but only on the principal amount so paid or prepaid), except that
      interest payable at the applicable Post-Default Rate shall be payable from
      time to time on demand by GFC in accordance with the provisions of the
      Borrower Indemnity Agreement.

                (iv) Promptly after the determination of any interest rate
      provided for herein or any change therein, in each case referable to a
      Loan, the Facility Agent shall give notice thereof to the Lenders, Ex-Im
      Bank, the relevant Borrower and GFC; provided that the Facility Agent's
      failure to so notify the Lenders, Ex-Im Bank, such Borrower and GFC shall
      not relieve such Borrower of its obligation to pay interest payable
      hereunder or the corresponding Lessee or any Guarantor of any obligation
      under any Operative Document nor shall it give rise to any claim against
      the Facility Agent by any Guarantor or such Borrower.

            (b) Ex-Im Bank Amounts.

                (i) Notwithstanding Section 3.2(a), if Ex-Im Bank shall have
      made a claim payment under the Ex-Im Bank Guarantee to the Lender with
      respect to a demand under a Floating Rate Note in respect of a Loan, then,
      beginning on the date of such claim payment, such Loan shall bear interest
      at a rate per annum equal to Special LIBOR for all purposes, including,
      without limitation, Section 3.2(b)(ii).

                (ii) Notwithstanding Section 3.2(a), if Ex-Im Bank shall have
      made a claim payment under the Ex-Im Bank Guarantee to the Facility Agent
      with respect to a demand under any Note, then, beginning on the date of
      such claim payment, if any

      amount of principal of or accrued interest on the Loans then owing to
      Ex-Im Bank is not paid in full when due, whether at stated maturity, by
      acceleration or otherwise, the relevant Borrower shall pay to Ex-Im Bank
      on demand interest on such unpaid amount for the period from and including
      the date such amount was due to Ex-Im Bank to but excluding the date such
      amount is paid in full at an interest rate per annum equal to one percent
      (1%) per annum above the interest rate then applicable under Section
      3.2(a) (as modified, if required, by Section 3.2(b)(i)).

                  (iii) Except as otherwise provided in Section 3.2(b)(ii) with
      respect to the amounts of principal and accrued interest, if, at any time,
      any other amount owing to Ex-Im Bank under this Agreement with respect to
      any Loan or the corresponding Note is not paid in full when due, the
      relevant Borrower shall pay to Ex-Im Bank on demand interest on such
      unpaid amount for the period from the date such amount was due (the
      "PAYMENT DEFAULT DATE") until such amount shall have been paid in full at
      an interest rate per annum equal to one percent (1%) per annum above the
      U.S. Treasury Rate for six-month (180 days) Treasury Bills which is in
      effect on the Payment Default Date.

      3.3 Promissory Notes. Each Borrower agrees that to further evidence its
obligation to repay its Loans, with interest thereon, it shall issue and deliver
to the Facility Agent on the Borrowing Date for each such Loan either a Floating
Rate Note or a Fixed Rate Note, as applicable; provided that at no time shall
there be more than one (1) Note per Loan. Subject to Section 3.4(b), each Note
as originally delivered to the Facility Agent shall (i) be dated as of the
relevant Borrowing Date, (ii) be in a principal amount equal to the amount of
the relevant Loan to be disbursed on such Borrowing Date, (iii) be substantially
in the form of Exhibit B-l or B-2 hereto, as the case may be, (iv) be repayable
as to principal in accordance with the provisions of this Agreement, (v) if such
Note is a Floating Rate Note, have a payment schedule providing for monthly
installments of principal on the relevant Loan Payment Dates calculated on a
"mortgage style" basis by application of an assumed interest rate equal to the
Relevant Rate for the relevant Loan resulting in increasing payments of
principal during the relevant repayment period, (vi) if such Note is a Fixed
Rate Note, have a payment schedule providing for quarterly installments of
principal on the relevant Loan Payment Dates calculated on a "mortgage style"
basis by application of an assumed interest rate equal to the applicable Fixed
Rate resulting in increasing payments of principal during the relevant repayment
period, (vii) bear interest in accordance with the appropriate provisions of
this Agreement, (viii) be otherwise in conformity with the terms of this
Agreement, and (ix) designate the applicable Aircraft to which it relates. Each
Note shall be the legal, valid and enforceable obligation of the relevant
Borrower and shall be enforceable against such Borrower in accordance with its
terms. If a Note is mutilated, lost, stolen or destroyed, the relevant Borrower
shall issue a new Note of the same date, type, maturity and denomination as the
Note so mutilated, lost, stolen or destroyed; provided that, in the case of a
mutilated Note, such mutilated Note shall be simultaneously delivered to the
relevant Borrower through Ex-Im Bank (for cancellation of the Ex-Im Bank
Guarantee endorsement affixed thereon) and in the case of a lost, stolen or
destroyed Note, there shall first be furnished to the relevant Borrower, the
corresponding Lessee, GFC and Ex-Im Bank an instrument of indemnity from the
Facility Agent which holds such Borrower, such Lessee, GFC and Ex-Im Bank
harmless from any actual loss on the purportedly destroyed, lost or stolen Note
and evidence of such loss, theft or destruction reasonably satisfactory to each
of them, together with an officer's certificate of such Borrower certifying and
warranting as to the due authorization, execution and

                                                                [Loan Agreement]

delivery of such new Note, and (if requested by Ex-Im Bank in its reasonable
discretion and at the sole cost of the Facility Agent) an opinion of such
Borrower's counsel as to due authorization, execution and delivery of such new
Note, and the legality, validity, binding nature and enforceability thereof.

      3.4 Conversion.

            (a) In respect of each Loan that initially bears interest at a
Floating Rate, subject to no Event of Loss in relation to the relevant Aircraft
or Default having occurred and being continuing, GFC (acting on behalf of the
relevant Borrower) may at any time upon not less than ten (10) Business Days'
prior written irrevocable notice (said notice being herein referred to as the
"CONVERSION Notice") to the Facility Agent and Ex-Im Bank, request that on the
Loan Payment Date referable to such Loan specified in such notice applicable to
the relevant Loan (a "CONVERSION DATE"), the rate of interest applicable to such
Loan shall be calculated by reference to a Fixed Rate. Each Borrower shall be
entitled to exercise one Conversion in respect of each Loan borrowed by it and
each such Conversion shall take place on the applicable Conversion Date.

            (b) Following receipt of a Conversion Notice from GFC (sent on
behalf of the relevant Borrower) pursuant to Section 3.4(a), the Facility Agent
shall on or prior to the Conversion Date determine the Fixed Rate in accordance
with Section 3.4(c) to be applicable to the relevant Loan as of the Conversion
Date and shall notify Ex-Im Bank, the Lender, such Borrower, and GFC of such
Fixed Rate.

            (c) The Fixed Rate for a Loan the subject of a Conversion Notice
shall be the rate agreed by the Facility Agent and GFC in accordance with the
definition thereof. Upon determination of the Fixed Rate for any Loan, the
Facility Agent shall advise Ex-Im Bank of the relevant Fixed Rate and shall
recalculate the repayment schedule of such Loan on the basis of the applicable
Fixed Rate for such Loan, and the Facility Agent shall submit such recalculated
schedule to GFC and Ex-Im Bank for approval.

            (d) Subject to the satisfaction of the conditions precedent set
forth in Section 7(b), not later than 10:00 a.m. (New York time) on the relevant
Conversion Date, the Facility Agent shall deliver to Ex-Im Bank the relevant
outstanding Floating Rate Note, and the relevant Borrower shall immediately (and
in any event not later than 10:00 a.m. (New York time)) deliver or procure the
delivery to the Facility Agent of, as a replacement for such Floating Rate Note,
an executed Fixed Rate Note. Each such Fixed Rate Note shall (i) be dated the
relevant Conversion Date, (ii) be in a principal amount equal to the amount of
the relevant Loan outstanding on such Conversion Date, (iii) have a payment
schedule providing for quarterly payments of principal on the remaining relevant
Loan Payment Dates calculated on a "mortgage style" by application of an assumed
interest rate equal to the applicable Fixed Rate resulting in increasing
payments of principal during the remaining part of the relevant repayment
period, (iv) be in substantially the form of Exhibit B-2 hereto, (v) be
otherwise in conformity with this Agreement and (vi) designate the applicable
Aircraft to which it relates. Provided that all the requirements of this Section
3.4 and of Section 3.05 of the Ex-Im Bank Guarantee have been satisfied, then on
and after such Conversion Date the relevant Loan shall, for all purposes hereof,

                                       7
<PAGE>

                                                                [Loan Agreement]

bear interest at the applicable Fixed Rate and be calculated in the manner
provided in Section 4.2.

            (e) Upon satisfaction of all relevant conditions precedent to a
Conversion as specified in Section 7(b) and in Section 3.05 of the Ex-Im Bank
Guarantee, receipt from the Facility Agent of the original Guarantee Legend on
the relevant Floating Rate Note and cancellation by the Facility Agent of such
Floating Rate Note, Ex-Im Bank shall endorse its Guarantee Legend upon the Fixed
Rate Note issued by the relevant Borrower pursuant to this Section 3.4 in
respect of such Conversion and deliver such Fixed Rate Note to the Facility
Agent.

      SECTION 4. Payments; Pro Rata Treatment; Computations; Etc.

      other amounts payable hereunder and owing by such Borrower which are due
      and unpaid and not otherwise provided for under this Section 4.1(c).

            (d) Each payment received by the Facility Agent hereunder or under
any other Operative Document for account of a Lender shall be paid promptly to
such Lender, in immediately available funds, to such account as such Lender
shall specify in writing to the Facility Agent, and payments received before
10:00 a.m. (New York time) at any place of payment for Ex-Im Bank shall be
remitted to Ex-Im Bank on that same day and any payments received after 10:00
a.m. (New York time) shall be remitted on the next succeeding Business Day.

            (e) If the due date for any payment under this Agreement would
otherwise fall on a day that is not a Business Day, such payment shall be made
on the next succeeding Business Day and the amount of interest payable with
respect thereto shall be adjusted accordingly.

      4.2 Computations. Interest on each Loan (excluding Post-Default Rate

        Fixed Rate Loan
        Prepayment of Loan                  20 Business Days

Each Notice of Borrowing hereunder shall (i) specify the date of borrowing
(which shall be a Business Day), the aggregate principal amount of the relevant
Loan to be borrowed on such date and whether such Loan is to bear interest at a
Fixed Rate or a Floating Rate, (ii) be in substantially the form of Exhibit A
hereto and (iii) be signed by GFC on behalf of the relevant Borrower or
Borrowers. Each Conversion Notice hereunder shall (i) specify the Conversion

such date and (ii) be signed by GFC on behalf of the relevant Borrower or
Borrowers. Any notice of prepayment shall (i) specify the date of prepayment
(which shall be a Business Day) and the related Aircraft, and the aggregate
principal amount of the relevant Loan to be prepaid on such date and (ii) be
signed by GFC on behalf of the relevant Borrower. Any notice of termination or
reduction of the Credit shall (i) specify the amount of the Credit to be
terminated and (ii) be signed by GFC on behalf of the Borrower Parties. The
Facility Agent shall promptly notify the Lenders of the contents of each such
notice.

      4.4 Non-Receipt of Funds by the Facility Agent. Where a sum is to be paid
hereunder to the Facility Agent for account of another Person, the Facility
Agent shall not be obliged to make the same available to that other Person until
it has been able to establish to its satisfaction that it has actually received
such sum. But if it does so and it proves to be the case that it had not
actually received such sum, then the Person to whom such sum was so made
available shall on request refund the same to the Facility Agent together with
an amount sufficient to indemnify the Facility Agent against any Claims it may
have suffered or incurred by reason of its having paid out such sum prior to its
having received such sum. This Section 4.4 shall not apply to Ex-Im Bank.

      4.5 Sharing of Payments, Etc.

            (a) Each Borrower agrees that, in addition to (and without
limitation of) any right of set off, bankers' lien or counterclaim a Lender may
otherwise have, each Lender shall be entitled, at its option, to offset balances
held by it for account of such Borrower at any of its offices, in Dollars or in
any other currency, against any principal of or interest on any of such Lender's
Loans owed by such Borrower, or any other amount payable by such Borrower to
such Lender hereunder, that is not paid when due (regardless of whether such
balances are then due to such Borrower), in which case it shall promptly notify
such Borrower and the Facility Agent thereof; provided that such Lender's
failure to give such notice shall not affect the validity thereof.

            (b) If any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) on
account of its portion of any Loan in excess of its ratable share of payments on
account of such Loan obtained by all the Lenders, such Lender shall forthwith
purchase from the other Lenders such participations in such Loan made by them as
shall be necessary to cause such purchasing Lender to share the excess payment
ratably with each of them, provided, however, that if all or any portion of such
excess payment is thereafter recovered from such purchasing Lender, such
purchase from each Lender shall be rescinded and such Lender shall repay to the
purchasing Lender the purchase price to the extent

                                       10
<PAGE>

                                                                [Loan Agreement]

of such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. Each affected Borrower agrees that any Lender
so purchasing a participation from another Lender pursuant to this Section
4.5(b) may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of offset) with respect to such participation as
fully as if such Lender were the direct creditor of such Borrower in the amount
of such participation. This provision shall apply as between the Lenders (other
than Ex-Im Bank) only and shall not apply to Ex-Im Bank.

            (c) This Section 4.5 shall not apply to any set-off, banker's lien,
counterclaim or similar right of Ex-Im Bank and, notwithstanding the foregoing
provisions of this Section 4.5 after any demand has been made on the Ex-Im Bank
Guarantee in respect of any Loan, all payments received by such Lender or the
Facility Agent pursuant to the terms of the Operative Documents shall be applied
in accordance with the terms of Section 21 of the Participation Agreement.

      4.6 Loan Register.

            (a) This Agreement is a registered agreement, and any Note issued
hereunder shall be a registered instrument. A manually signed copy of this
Agreement and any Note shall be evidence of each Lender's and the Facility
Agent's rights and is not a bearer instrument. The Facility Agent will establish
and maintain at its office a record of ownership in which the Facility Agent
hereby covenants and agrees to register by book entry each Lender's interest in
each Loan, this Agreement and each Note, and in the rights to receive any
payments hereunder or thereunder and any transfer of any such interest or
rights.

            (b) No transfer by a Lender (whether or not with the consent of the
Borrowers) of any interest in the Loans, this Agreement or the Notes or in the
rights to receive any payments hereunder or thereunder shall be effective unless
a book entry of such transfer is made upon the record referred to above and such
transfer is effected in compliance with the terms of this Agreement. No such
transfer shall be effective until, and such transferee shall succeed to the
rights of the transferor Lender only upon, final acceptance and entry into the
record of ownership of the transfer pursuant hereto.

            (c) Prior to the entry into the record of ownership of any transfer
by the transferring Lender as provided in Section 4.6(b), the Borrowers, the
Facility Agent and each other Person shall be entitled to deem and treat each
Person reflected in the record of ownership as owner of a portion of the Loans,
this Agreement or the Notes, or the rights to receive any payments hereunder or
thereunder as the owner thereof for all purposes. Each Borrower agrees that the
record of ownership referred to in this Section 4.6 shall be conclusive and
binding on such Borrower absent manifest error. The Borrowers irrevocably
instruct the Facility Agent to enter into such record of ownership any such
transfer if all of the requirements set forth in this Agreement for an effective
transfer by a Lender of any interest in Loans shall then have been satisfied.
Any such entry by the Facility Agent shall be effective for the purposes of
determining the effectiveness of any transfer notwithstanding any revocation of
the agency granted and appointed herein.

      4.7 Fees. The following fees shall be payable

            (a) the Initial Borrower Party shall pay to Ex-Im Bank a guarantee

the Ex-Im Bank Commitment, computed on the basis of a 360 day year and the
actual number of days elapsed (including the first day but excluding the last
day), accruing from June 23, 2002 until the earliest of (i) the date the Ex-Im
Bank Commitment is fully disbursed, (ii) the date the undisbursed portion of the
Ex-Im Bank Commitment is cancelled by GFC (on behalf of the Borrower Parties) by
notice in writing to Ex-Im Bank and (iii) the relevant Final Disbursement Date
and payable in arrears on each Borrowing Date, each Loan Payment Date and each
Final Disbursement Date;

            (b) the Initial Borrower of any Loan shall pay to Ex-Im Bank an
exposure fee (the "EX-IM BANK EXPOSURE Fee") in Dollars in an amount equal to
3.0% of the principal amount of such Loan (less the portion thereof relating to
the Ex-Im Bank Exposure Fee) on the Borrowing Date in respect of such Loan.

      4.8 Reimbursement Obligations.

            (a) In consideration of Ex-Im Bank's entering into the Ex-Im Bank
Guarantee, each Borrower hereby irrevocably and unconditionally undertakes and
agrees with Ex-Im Bank, without duplication of any amounts paid by such Borrower
under the Participation Agreement, (i) to reimburse Ex-Im Bank immediately upon
demand for all amounts paid by Ex-Im Bank under and in respect of the Ex-Im Bank
Guarantee in relation to any of its Loans (it being agreed that if Ex-Im Bank
shall issue a Payment Certificate, the reimbursement obligation set forth in
this clause (i) shall include the aggregate face amount of all such Payment
Certificates so issued) or in the exercise of any right in respect thereof
provided by Applicable Law, (ii) to pay to Ex-Im Bank, for Ex-Im Bank's own
account, the Ex-Im Bank Make-Whole Amount, if any, in relation to each of its
Loans calculated by Ex-Im Bank as of the Calculation Date (as such term is
defined in the definition of Ex-Im Bank Make-Whole Amount), and (iii) (without
duplication of the foregoing) to indemnify Ex-Im Bank on a full indemnity basis
against all actions, proceedings, claims, demands, costs, charges, damages,
losses, costs and expenses (including, without limitation, consequential
damages) made, suffered or incurred by Ex-Im Bank and to pay to Ex-Im Bank
immediately upon demand for all payments, costs, damages, losses or expenses of
any description whatsoever which may be incurred by Ex-Im Bank in connection
with any investigative, administrative or judicial proceeding in relation to or
arising out of the Ex-Im Bank Guarantee in connection with each of its Loans.

            (b) All payments to be made by any Borrower to Ex-Im Bank under this
Agreement or any other Operative Document shall (except as otherwise provided in
Section 9 of the Participation Agreement) be in Dollars. All payments to Ex-Im
Bank in Dollars shall be made at the Federal Reserve Bank in New York for credit
to Ex-Im Bank's account with the Treasurer of the United States, Washington,
D.C., U.S.A., in accordance with the payment instructions set forth in Section
4.l(a). Whenever any payment to Ex-Im Bank under this Agreement or any other
Operative Document shall be stated to be due and payable on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day
with interest at the rate provided for in Section 3.2.

                                                                [Loan Agreement]

      4.9 Transfer. Each Borrower acknowledges that upon payment of any amounts
by Ex-Im Bank under the Ex-Im Bank Guarantee in relation to any of its Loans,
Ex-Im Bank shall be subrogated (by way of an assignment, by operation of law or
otherwise) to all of the rights of the Lenders in relation to the relevant Loan
or Loans under the Operative Documents (excluding, for the avoidance of doubt,
the Borrower Indemnity Agreement) to the extent set forth in the Ex-Im Bank
Guarantee and in this Agreement. Each Borrower hereby consents and agrees that
Ex-Im Bank is a permitted assignee and transferee of any Lender for all purposes
of this Agreement and any other Operative Document.

      4.10 Waiver. Each Borrower acknowledges and agrees that if any covenant,
stipulation or other provision of this Agreement which imposes on such Borrower
the obligation to make any payment, whether by way of indemnity or otherwise, is
at any time void under any provision of Applicable Law (including, without
limitation, the Applicable Law of any Relevant Jurisdiction) such Borrower will
not make any claim, counterclaim or institute any proceedings against Ex-Im
Bank, the Facility Agent, any Lender or any of their respective assignees or
subrogees for any amount paid by such Borrower at any time, and (to the extent
permitted by Applicable Law) such Borrower waives unconditionally and absolutely
any rights and defenses, legal or equitable, which arise under or in connection
with any such provision relating thereto against or in connection with any claim
or proceeding brought by such Borrower for recovery of any amount due under any
Operative Document.

      4.11 Payments Absolute. The reimbursement and indemnity obligations of
each Borrower hereunder shall be absolute, unconditional and irrevocable, and
shall to the full extent provided by Applicable Laws be paid strictly in
accordance with the terms of this Agreement, under all circumstances whatsoever,
including, without limitation, the following circumstances: (a) any lack of
legality, validity, regularity or enforceability of this Agreement or any other
Operative Documents; (b) any amendment or waiver of or any consent given under
any of the Operative Documents; (c) the existence of any claim, set-off, defense
or other rights which any Person may have at any time against Ex-Im Bank, the
Facility Agent, the Security Trustee, the Lenders or any other Person or entity,
whether in connection with this Agreement, the other Operative Documents or any
unrelated transaction; provided that the foregoing shall not prohibit the
assertion of any such claim or defense by separate suit or counterclaim; and (d)
any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, which could be interpreted as a legal or equitable defense to
payment hereunder or under any other Operative Document.

      4.12 Payments under Ex-Im Bank Guarantee. If Ex-Im Bank shall have
received a demand for payment under the Ex-Im Bank Guarantee, and Ex-Im Bank
shall not have been reimbursed in full on the same Business Day of the date of
demand, Ex-Im Bank may (without prejudice to any rights it may have to take any
such action prior to the date of such demand) thereafter exercise any of the
rights and remedies granted to it for exercise after an Event of Default under
any Lease, any Security Document the GATX Guarantee or this Agreement.

      SECTION 5. Taxes; Indemnities.

      5.1 Taxes. Each Borrower Party covenants and agrees that, whether or not a
Loan is made hereunder: (a) all payments by it to Ex-Im Bank under or in respect
of this Agreement,

                                                                [Loan Agreement]

including amounts payable under clause (b) and (c) of this sentence, shall be
made free and clear of and without reduction by reason of any Taxes, all of
which will be paid by it to the appropriate taxing authority at the time and in
the manner prescribed by Applicable Laws; (b) it will indemnify Ex-Im Bank
against, and reimburse Ex-Im Bank on demand for, any Taxes and any interest,
additions, fines or penalties thereon related to Ex-Im Bank's function as
guarantor of the Loans made to it; (c) in the event that it is required by
Applicable Laws to deduct or withhold any Taxes from any amounts payable by it
to Ex-Im Bank on, under or in respect of this Agreement or any Loan contemplated
by this Agreement or any Note contemplated by this Agreement, it shall pay, on
demand of Ex-Im Bank, to Ex-Im Bank, such additional amount or amounts as may be
required in order that the amount received after deduction or withholding shall
equal the full amount stated to be payable under this Agreement as if such
deduction or withholding had not been required; (d) it shall promptly furnish to
Ex-Im Bank satisfactory official Tax receipts in respect of any payment of Taxes
paid by it pursuant to this Section 5.1; (e) its covenants and agreements under
this Section 5 shall survive the repayment of its Loans (if any). Without
prejudice to the obligations of each Borrower Party under the foregoing
sentence, in the event and to the extent that such Borrower Party is required by
Applicable Laws to deduct or withhold any Tax from any payment due hereunder to
Ex-Im Bank in respect of this Agreement or any Loan or any Note, then such
Borrower Party agrees to withhold from each such payment due hereunder such
withholding Taxes at the appropriate rate, and will, on a timely basis and in
the manner required by Applicable Law, deposit such amounts with an authorized
depository or other relevant Government Body and make such reports, filings and
other reports in connection therewith. Each Borrower Party shall promptly
furnish to Ex-Im Bank (but in no event later than the date thirty (30) days
after the due date thereof) the completed relevant form or forms and/or official
Tax receipts indicating the payment in full of any Tax withheld from any
payments made by it for account of Ex-Im Bank, together with all such other
information and documents reasonably requested by Ex-Im Bank's counsel. If any
Borrower Party fails to pay any such withholding Taxes when due or fails to
remit to Ex-Im Bank the required receipts or other required documentary
evidence, such Borrower Party, as the case may be, shall indemnify and reimburse
on demand Ex-Im Bank on an After-Tax Basis for any Taxes, interest, additions,
fines or penalties that may become payable as a result of any such failure.

      5.2 Grossing-up of Indemnity Provisions. Wherever in this Agreement any
Borrower has an obligation to indemnify or reimburse Ex-Im Bank in respect of
any loss or payment (including, without limitation, obligations of the relevant
Borrower to make a payment to or reimburse Ex-Im Bank in respect of Taxes,
expenses or indemnities), the amount payable shall include the amount necessary
to hold Ex-Im Bank harmless on an After-Tax Basis (computed by taking into
account the credit or deduction with respect to such loss or payment available
to Ex-Im Bank in its reasonable determination without Ex-Im Bank being under any
obligation to utilize any credit or deduction for any particular purpose), so as
to leave Ex-Im Bank in the same After-Tax position as it would have been in had
the indemnity or reimbursement payment made to Ex-Im Bank not given rise to any
liability for any Tax.

      SECTION 6. Substitutions. If a Substitution occurs under Section 6B of the
Participation Agreement with respect to a Borrower then, with effect from the
relevant Substitution Date, all references to such Borrower hereunder and in the
related Notes shall be taken to be references to the relevant Replacement
Person, as if the Replacement Person had originally been a party hereunder as a
Borrower in respect of the relevant Loan or Loans.

      SECTION 11. The Facility Agent.

      11.1 Appointment, Powers and Immunities. Each Lender (other than Ex-Im
Bank) hereby appoints the Facility Agent to act as its facility agent in
connection herewith and with the other Operative Documents and authorizes the

together with all such rights, powers and discretions as are reasonably
incidental thereto.

            (a) assume that:

                  (i) any representation made by any person (other than the

      Document is true;

                  (ii) no Borrower or Lessee is in breach of or in default under
      its obligations under any other Operative Document to which it is a party;

                  (iii) any right, power, authority or discretion vested herein
      upon Majority Lenders, the Lenders or any other person or group of persons
      has not been exercised, unless it has, in its capacity as Facility Agent,
      actual knowledge or actual notice to the contrary;

            (b) assume that the Lending Office of each Lender is that identified
below its signature hereto until it has received from such Lender a notice
designating some other office of such Lender to replace its Lending Office, or
in the case of Ex-Im Bank after a transfer pursuant

                                       18
<PAGE>

                                                                [Loan Agreement]

and act upon any such notice until the same is superseded by a further such
notice;

            (c) engage and pay for the advice or services of any lawyers,

a certificate signed by or on behalf of such party;

            (e) rely upon any communication or document believed by it to be
genuine;

            (f) subject to the provisions of the Security Documents and the
Ex-Im Bank Guarantee, refrain from exercising any right, power or discretion
vested in it as Facility Agent hereunder unless and until instructed by the
Majority Lenders (or other percentage of Lenders as may be specified herein) as
to whether or not such right power or discretion is to be exercised and, if it
is to be exercised, as to the manner in which it should be exercised;

            (g) subject to the provisions of the Security Documents, refrain
from acting in accordance with any instructions of the Majority Lenders to begin
any legal action or proceeding arising out of or in connection with this
Agreement or any other Operative Document until it shall have received such
security as it may require (whether by way of payment in advance or otherwise)
for all costs, claims, expenses (including legal fees) and liabilities which it
will or may expend or incur in complying with such instructions; and

            (h) subject to the provisions of the Ex-Im Bank Guarantee and the
Security Documents, take such action as is, in the reasonable opinion of the
Facility Agent, necessary or advisable to preserve all or any of the rights of

such action.

      11.3 Notices; Defaults. The Facility Agent shall:

Operative Document to the extent that such notice or document shall not have
been furnished, or not required to be furnished by another party, to such Lender
and Ex-Im Bank, provided that in the case of a notice from any Lender to the
Facility Agent of any Event of Default under this Agreement or any Event of
Default under the Lease, or any event which, with the giving of notice, the
passage of time, or both, would become an Event of Default hereunder or under
the Lease, the Facility Agent shall promptly and in any event within thirty (30)
days of receipt thereof inform each Lender and Ex-Im Bank of the contents of
such notice;

            (b) promptly, and in any event within thirty (30) days of actual
knowledge or actual notice thereof in its capacity as Facility Agent, notify

      connection herewith or with any other Operative Document is true;

                  (ii)  the performance by any party of its obligations
      hereunder or under any other Operative Document; or

            (c)   be bound to disclose to any other Person any information

            (d)   be under any obligations other than those for which express
provision is made herein.

      11.5  Dealings with Parties. The Facility Agent may accept deposits from,
lend money to and generally engage in any kind of banking or other business with
any party to the Operative Documents. Notwithstanding any other provision hereof
or of any other Operative Document, at no time shall the Facility Agent be
acting or required to act as agent for Ex-Im Bank.

      11.6  Indemnification. Each Lender (other than Ex-Im Bank) shall, from
time to time on demand by the Facility Agent indemnify the Facility Agent, in
the proportion that, prior to the first Loan being made hereunder, its
Commitment bears to the Credit, and, thereafter, its share of the Loans bears to
the aggregate amount of the Loans at the time of such demand (or, if the Loans
have then been repaid in full, immediately prior to the final repayment
thereof), against any and all costs, claims, expenses (including legal fees) and
liabilities which the Facility Agent

                                       20

<PAGE>

                                                                [Loan Agreement]

may incur in acting in its capacity as facility agent hereunder and under the
other Operative Documents; provided that no Lender shall be liable for any of
the foregoing to the extent they arise from the gross negligence or willful
misconduct of the Facility Agent.

      11.7  Extent of Responsibility. Except to the extent representations,
warranties and covenants are given in the Operative Documents in its capacity as
Facility Agent or in its individual capacity and except to the extent set forth
in the Ex-Im Bank Guarantee, the Facility Agent accepts no responsibility for
the accuracy and/or completeness of information supplied by any party to the
Operative Documents in connection herewith or for the legality, validity,
effectiveness, adequacy or enforceability of this Agreement or any other
Operative Document and the Facility Agent shall not be under any liability as a
result of taking or omitting to take any action in relation to this Agreement or
any other Operative Document, save in the case of gross negligence or wilful
misconduct in relation to such action or omission, and each Lender agrees that
it will not assert or seek to assert against any director, office or employee of
the Facility Agent any claim it might have against any of them in respect of the
matters referred to in this Section 11.7.

      11.8  Affiliates of Facility Agent. In order to fulfil its
responsibilities as Facility Agent, the Facility Agent may obtain information or
advice from any of its Affiliates, in which regard it is acknowledged and agreed
by each Lender that the Facility Agent and any such Affiliate shall each be
fully entitled to seek and rely upon any such information and advice and that
any such Affiliate shall be entitled to the benefit of the foregoing provisions
of this Section 11 in relation thereto in all respects and in the same manner as
the Facility Agent.

      11.9  Non-Reliance on Facility Agent. It is understood and agreed by each
Lender that it has itself been, and will continue to be, solely responsible for
making its own independent appraisal of and investigations into the financial
condition, creditworthiness, condition, affairs, status and nature of each of
the parties to the Operative Document and, accordingly, each Lender warrants to
the Facility Agent that it has not relied and will not hereafter rely on the
Facility Agent:

            (a)   to check or inquire on its behalf into the adequacy, accuracy
or completeness of any information provided by any party to the Operative
Documents in connection with this Agreement or any other Operative Documents or
the transactions herein contemplated (whether or not such information has been
or is hereafter circulated to such Lender by the Facility Agent); or

            (b)   to assess or keep under review on its behalf the financial
condition, creditworthiness, condition, affairs, status or nature of any party
to the Operative Documents.

      Upon learning of the occurrence of any Event of Default under this
Agreement or any Event of Default under any Lease, or any event which with the
giving of notice, the passage of time or both would become an Event of Default
under this Agreement or any Lease, each Lender hereby agrees to promptly notify
the Facility Agent thereof and in any event, within ten (10) days.

      11.10 No Duties Except as Specified. The Facility Agent shall have only
those duties, obligations and responsibilities which are expressly specified in
this Agreement and any other Operative Document to which the Facility Agent is a
party.

Agent may resign at any time by giving notice thereof to the Lenders, Ex-Im
Bank, the Initial Borrower Party and GFC and the Facility Agent may be removed
at any time with or without cause by the Majority Lenders. Upon any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Facility Agent. Any successor Facility Agent appointed hereunder shall

reasonably acceptable to Ex-Im Bank, the Majority Lenders and, provided no Lease
Event of Default has occurred and is continuing, GFC, having at least U.S $1
billion in capital and surplus (or such other amount as approved by Ex-Im Bank).
If no successor Facility Agent shall have been so appointed by the Majority
Lenders and shall have accepted such appointment within 30 days after the
retiring Facility Agent's giving of notice of resignation or the Majority
Lenders' removal of the retiring Facility Agent, then the retiring Facility
Agent may, on behalf of the Lenders appoint a successor Facility Agent having at
least U.S. $1 billion in capital and surplus (or such other amount as approved
by Ex-Im Bank). Upon the acceptance of any appointment as Facility Agent
hereunder by a successor Facility Agent, such successor Facility Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Facility Agent, and the retiring Facility Agent shall
be discharged from its duties and obligations hereunder After any retiring
Facility Agent's resignation or removal hereunder as Facility Agent, the
provisions of this Section 11 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Facility Agent.

      11.12 Agency Division Separate. In acting as Facility Agent hereunder for
the Lenders, the Facility Agent shall be regarded as acting through its agency
division which shall be treated as a separate entity from any other of its
divisions or departments.

      11.13 Confidential Information. Notwithstanding anything to the contrary
expressed or implied herein and without prejudice to the provisions of Section
11.12 or Section 12.6(d) or Section 14 of the Participation Agreement, the
Facility Agent shall not as between itself and the Lenders be bound to disclose
to any Lender or other person any information which is supplied by any Borrower,
any Borrower Party, any Guarantor, any Lessee or any Lessee Party to any
division or department of the Facility Agent (other than the agency division of
the Facility Agent) and which is identified at the time it is so supplied as
being confidential information.

      11.14 Demand for Payment. For purposes of permitting the Facility Agent to
make demand under the Ex-Im Bank Guarantee, the Facility Agent may (but not to
the exclusion of the Security Trustee or Ex-Im Bank) make demand on each of any
Borrower, any Borrower Party, any Lessee, any Lessee Party and any Guarantor
under any Operative Document for payments of any amounts due and owing from and
unpaid by such Person under any Lease and/or the GATX Guarantee and/or the Loan
Agreement. Notwithstanding any other provision of this Agreement or any other
Operative Document to the contrary, if the Facility Agent is entitled to make a
demand for payment against Ex-Im Bank under the Ex-Im Bank Guarantee, the
Facility Agent

shall make such demand if so instructed by any Lender without reference to the
Majority Lenders,

      SECTION 12. Miscellaneous.

      12.1  No Waiver. No failure on the part of the Facility Agent, the
Security Trustee, Ex-Im Bank or any Lender to exercise and no delay in
exercising, and no course of dealing with respect to, any right, power or
privilege under this Agreement shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power or privilege under this Agreement
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law.

      12.2  Notices. Each of the parties hereby acknowledges and confirms that
this Loan Agreement and each of the Notes is one of the Operative Documents and
as a result all of the provisions of Section 30(c) of the Participation

are to be made hereunder, (b) the time as of which such notices or
communications shall be deemed to have been given or made, and (c) the address
to which such notices or communications are to be sent).

Agreement or the Participation Agreement, any provision of this Agreement may be
amended or modified only by an instrument signed by GFC (acting on behalf of the
Borrowers and the Borrower Parties), Ex-Im Bank and, provided no claim has been
made under the Ex-Im Bank Guarantee, the Facility Agent (acting at the direction
of the Majority Lenders), and any provision of this Agreement may be waived by
the Facility Agent (acting at the direction of the Majority Lenders) and Ex-Im
Bank; provided that no amendment, modification or waiver shall, unless by an

with the consent of all of the Lenders: (i) increase or extend the term, or
extend the time or waive any requirement for the termination, of the

Section 11, or that increases the obligations of the Facility Agent hereunder or
of Ex-Im Bank under any Operative Document, shall require the consent of Ex-Im
Bank and the Facility Agent.

      12.4  Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns.

      12.5  Assignments and Participations.

            (a)   Except as expressly permitted in the Operative Documents, no
Borrower or Borrower Party may assign or transfer its rights or delegate its
obligations hereunder or under

                                       23

                                                                [Loan Agreement]

any other Operative Document without the prior consent of GFC, Ex-Im Bank and
the Facility Agent.

            (b)   Any Lender may at any time (i) change its Lending Office or
Lending Offices to any other office of such Lender upon giving prior written
notice of such change to the Facility Agent, the Borrowers and the Borrower
Parties and/or (ii) with the prior written approval of GFC (such approval not to
be unreasonably withheld or delayed and not to be required in relation to any
such assignment or transfer made at any time when an Event of Default has
occurred and is continuing), assign or transfer all or any of its rights,
benefits and obligations hereunder to any one or more banks or financial
institutions in accordance with Section 12.5(e). Upon delivery of a completed
Transfer Certificate by the assigning Lender to the Facility Agent, GFC, each
Borrower and each Borrower Party, the assignee shall, on and as of the Transfer
Date specified therein, have, to the extent of such assignment or transfer, the
obligations, rights and benefits of a Lender hereunder holding a portion of the
Loan or Loans assigned or transferred to it (in addition to the portion of the
Loans, if any, theretofore held by such assignee) and the assigning or
transferring Lender shall, to the extent of such assignment or transfer have no
further rights hereunder or under the related Notes and shall be released from
the Commitment (or portion thereof) so assigned or transferred, provided that
(other than in connection with an assignment to Ex-Im Bank) if any change in
Lending Office or assignment or transfer would subject any Borrower, any
Borrower Party, any Lessee, any Lessee Party or any Guarantor to any greater
obligation or liability under the Borrower Indemnity Agreement or any other
Operative Document than it would have been under on such date if no such change
in Lending Office, assignment or transfer had then taken place, then unless such
change in Lending Office, assignment or transfer was made at the request of GFC
to mitigate or avoid the requirement for payment of additional amounts or
increased costs under or any illegality under the Borrower Indemnity Agreement
or any other Operative Document, the relevant Lender, assignee or transferee
shall not be entitled to receive any greater payment under the Borrower
Indemnity Agreement or any other Operative Document than such Lender, the
assignor or transferor would have been entitled to receive had no such change in
Lending Office, assignment or transfer taken place. No Transfer Certificate
shall be required in the case of an assignment or transfer by a Lender to Ex-Im
Bank required pursuant to the terms of the Ex-Im Bank Guarantee, but the effect
of any such assignment or transfer shall be the same as set out in the preceding
sentence, notwithstanding that the Transfer Certificate shall not have been
given.

            (c)   Without limiting the provisions of Section 14 of the
Participation Agreement or Section 11.13 of this Agreement, all non-public
information provided to the Facility Agent, the Security Trustee and the Lenders
by any Borrower, any Borrower Party, any Guarantor, any Lessee or any Lessee
Party shall be treated as confidential by the Facility Agent, the Security
Trustee and the Lenders, provided, however, that any Lender may furnish any
information concerning any Borrower, any Borrower Party, any Guarantor, any
Lessee or any Lessee Party in the possession of such Lender from time to time to
assignees and participants (including bona fide prospective assignees and
participants), provided such Persons have agreed to maintain the confidentiality
of all such non-public information so furnished and any such information may be
disclosed as required by Applicable Laws.

            (d)   On the date upon which an assignment or transfer takes place
pursuant to the foregoing provisions the assignee or transferee (other than
Ex-Im Bank) shall pay to the

                                       24

                                                                [Loan Agreement]

Facility Agent for its own account a fee of US$2,500, it being understood that
the Facility Agent shall have no recourse to any party to the Operative
Documents (other than such assignee or transferee) for the payment of such fee.

            (e)   If any Lender (other than Ex-Im Bank) wishes to assign or
transfer all or any of its rights, benefits and obligations hereunder as
contemplated in Section 12.5(b), then such assignment or transfer may be
effected (i) in the case of an assignment or transfer to a Person (other than
Ex-Im Bank) on the Transfer Date specified in the relevant Transfer Certificate
or (ii) in the case of a transfer or assignment to Ex-Im Bank as a result of a
demand under the terms of the Ex-Im Bank Guarantee, on the date of such
transfer. To the extent that pursuant to such Transfer Certificate and the
provisions thereof the rights and obligations of such Lender hereunder and under
the other Operative Documents (to which the Lenders are party) are validly
transferred to and assumed by the assignee or transferee, such Lender shall be
released from further obligations hereunder and under the other Operative
Documents, other than accrued rights owing to any party hereunder and
thereunder.

            (f)   No Lender (other than Ex-Im Bank, any of its transferees or
any further transferees) may assign or transfer any of its rights or obligations
hereunder as contemplated by this Section 12.5 unless contemporaneously
therewith it assigns or transfers to the same assignee or Transferee all or a
corresponding part of its rights, benefits and obligations under each of the
other Operative Documents to which such Lender is party. Further, if any Lender
assigns or transfers to any assignee or Transferee the corresponding proportion
of its interest in the Notes, and if the Facility Agent assigns or transfers its
right to receive payment hereunder no such transfer or assignment or transfer by
such Lender or by the Facility Agent shall be effective unless the Facility
Agent records such assignee's or Transferee's interest in the Notes or the
assigned or transferred right of the Facility Agent to receive payment hereunder
in the register that the Facility Agent is required to maintain in accordance
with Sections 4.6 hereof and 5.01 of the Ex-Im Bank Guarantee, such entry to be
conclusive and binding, save in the case of manifest error.

            (g)   Any assigning or transferring Lender (other than Ex-Im Bank
and any subsequent Transferees) shall be solely responsible for (and such Lender
will not seek indemnification from any Borrower, any Borrower Party, any
Guarantor, any Lessee or any Lessee Party in respect of) all of its costs and
expenses for any assignment, transfer or participation under this Section 12.6
including, without limitation, all costs in connection with any amendment to or
supplement to, or registration of or re-registration of the Security Documents
and any legal fees and expenses relating thereto (or may procure that any
Transferee or participant pay such costs and expenses), unless such assignment
or transfer was effected at the request of GFC to mitigate the imposition of any
Claims.

      12.6  GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK, UNITED STATES OF
AMERICA, WITHOUT REFERENCE TO PRINCIPLES OF CONFLICTS OF LAW OTHER THAN SECTIONS
5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

in any jurisdiction, then, to the fullest extent permitted by law, (i) the other
provisions hereof shall remain in full force and effect in such jurisdiction and
shall be liberally construed in favor of the Lenders and Ex-Im Bank in order to

SECURITY TRUSTEE AND THE LENDERS HEREBY KNOWINGLY, VOLUNTARILY, AND
INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF
