                                   ARTICLE II

                       AMOUNT AND TERMS OF THE COMMITMENT

            Section 2.01. THE ADVANCES. The Liquidity Provider hereby
irrevocably agrees, on the terms and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the period
from the Effective Date until 1:00 P.M. (New York City time) on the Expiry Date
(unless the obligations of the Liquidity Provider shall be earlier terminated in
accordance with the terms of Section 2.04(b)) in an aggregate amount at any time
outstanding not to exceed the Maximum Commitment.

            Section 2.02. MAKING THE ADVANCES. (a) Interest Advances shall be
made in one or more Borrowings by delivery to the Liquidity Provider of one or
more written and completed Notices of Borrowing in substantially the form of
Annex I attached hereto, signed by a Responsible Officer of the Borrower, in an
amount not exceeding the Maximum Available Commitment at such time and shall be
used solely for the payment when due of interest on the Class A-2 Certificates
at the Stated Interest Rate therefor in accordance with Section 3.6(a) of the
Intercreditor Agreement. Each Interest Advance made hereunder shall
automatically reduce the Maximum Available Commitment and the amount available
to be borrowed hereunder by subsequent Advances by the amount of such Interest
Advance (subject to reinstatement as provided in the next sentence). Upon
repayment to the Liquidity Provider in full of the amount of any Interest
Advance made pursuant to this Section 2.02(a), together with accrued interest
thereon (as provided herein), the Maximum Available Commitment shall be
reinstated by the amount of such repaid Interest Advance, but not to exceed the
Maximum Commitment; PROVIDED, HOWEVER, that the Maximum Available Commitment
shall not be so reinstated at any

                                       7
<Page>

time if (i) a Liquidity Event of Default shall have occurred and be continuing
and (ii) there is a Performing Note Deficiency.

            (b) A Non-Extension Advance shall be made in a single Borrowing if
this Agreement is not extended in accordance with Section 3.6(d) of the
Intercreditor Agreement (unless a Replacement Liquidity Facility to replace this
Agreement shall have been delivered to the Borrower as contemplated by said
Section 3.6(d) within the time period specified in such Section) by delivery to
the Liquidity Provider of a written and completed Notice of Borrowing in
substantially the form of Annex II attached hereto, signed by a Responsible
Officer of the Borrower, in an amount equal to the Maximum Available Commitment
at such time, and shall be used to fund the Class A-2 Cash Collateral Account in
accordance with said Section 3.6(d) and Section 3.6(f) of the Intercreditor
Agreement.

            (c) A Downgrade Advance shall be made in a single Borrowing upon the
occurrence of a Downgrade Event (as provided for in Section 3.6(c) of the
Intercreditor Agreement) unless a Replacement Liquidity Facility to replace this
Agreement shall have been previously delivered to the Borrower in accordance
with said Section 3.6(c), by delivery to the Liquidity Provider of a written and
completed Notice of Borrowing in substantially the form of Annex III attached
hereto, signed by a Responsible Officer of the Borrower, in an amount equal to
the Maximum Available Commitment at the time of such borrowing, and shall be
used to fund the Class A-2 Cash Collateral Account in accordance with said
Section 3.6(c) and Section 3.6(f) of the Intercreditor Agreement.

            (d) A Final Advance shall be made in a single Borrowing upon the
receipt by the Borrower of a Termination Notice from the Liquidity Provider
pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of Annex IV
attached hereto, signed by a Responsible Officer of the Borrower, in an amount
equal to the Maximum Available Commitment at such time, and shall be used to
fund the Class A-2 Cash Collateral Account in accordance with Section 3.6(i) and
Section 3.6(f) of the Intercreditor Agreement.

            (e) Each Borrowing shall be made on notice in writing (a "NOTICE OF
BORROWING") in substantially the form required by Section 2.02(a), 2.02(b),
2.02(c) or 2.02(d), as the case may be, given by the Borrower to the Liquidity
Provider. If a Notice of Borrowing is delivered by the Borrower in respect of
any Borrowing no later than 1:00 p.m. (New York City time) on a Business Day,
upon satisfaction of the conditions precedent set forth in Section 4.02 with
respect to a requested Borrowing, the Liquidity Provider shall make available to
the Borrower, in accordance with its payment instructions, the amount of such
Borrowing in U.S. dollars and immediately available funds, before 4:00 p.m. (New
York City time) on such Business Day or on such later Business Day specified in
such Notice of Borrowing. If a Notice of Borrowing is delivered by the Borrower
in respect of any Borrowing after 1:00 p.m. (New York City time) on a Business
Day, upon satisfaction of the conditions precedent set forth in Section 4.02
with respect to a requested Borrowing, the Liquidity Provider shall make
available to the Borrower, in accordance with its payment instructions, the
amount of such Borrowing in U.S. dollars and immediately available funds, before
12:00 Noon (New York City time) on the first Business Day next following the day
of receipt of such Notice of Borrowing or on such later Business Day specified
by the Borrower in such Notice of Borrowing. Payments of proceeds of a Borrowing

                                       8
<Page>

shall be made by wire transfer of immediately available funds to the Borrower in
accordance with such wire transfer instructions as the Borrower shall furnish
from time to time to the Liquidity Provider for such purpose. Each Notice of
Borrowing shall be irrevocable and binding on the Borrower. Each Notice of
Borrowing shall be effective upon delivery of a copy thereof to the Liquidity
Provider's New York Branch at the address specified in Section 7.02 hereof.

            (f) Upon the making of any Advance requested pursuant to a Notice of
Borrowing, in accordance with the Borrower's payment instructions, the Liquidity
Provider shall be fully discharged of its obligation hereunder with respect to
such Notice of Borrowing, and the Liquidity Provider shall not thereafter be
obligated to make any further Advances hereunder in respect of such Notice of
Borrowing to the Borrower or to any other Person. If the Liquidity Provider
makes an Advance requested pursuant to a Notice of Borrowing before 12:00 Noon
(New York City time) on the second Business Day after the date of payment
specified in said Section 2.02(e), the Liquidity Provider shall have fully
discharged its obligations hereunder with respect to such Advance and an event
of default shall not have occurred hereunder. Following the making of any
Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the Class A-2
Cash Collateral Account, the Liquidity Provider shall have no interest in or
rights to the Class A-2 Cash Collateral Account, the funds constituting such
Advance or any other amounts from time to time on deposit in the Class A-2 Cash
Collateral Account; PROVIDED that the foregoing shall not affect or impair the
obligations of the Subordination Agent to make the distributions contemplated by
Section 3.6(e) or (f) of the Intercreditor Agreement and provided further, that
the foregoing shall not affect or impair the rights of the Liquidity Provider to
provide written instructions with respect to the investment and reinvestment of
amounts in the Cash Collateral Accounts to the extent provided in Section 2.2(b)
of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances
requested by the Borrower in accordance with the provisions of this Agreement,
the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the amount
of the Advances so made and requested.

            Section 2.03. FEES. The Borrower agrees to pay to the Liquidity
Provider the fees set forth in the Fee Letter applicable to this Agreement.

            Section 2.04. REDUCTION OR TERMINATION OF THE MAXIMUM COMMITMENT.

            (a) AUTOMATIC REDUCTION. Promptly following each date on which the
Required Amount is reduced as a result of a reduction in the Pool Balance of the
Class A-2 Certificates or otherwise, the Maximum Commitment shall automatically
be reduced to an amount equal to such reduced Required Amount (as calculated by
the Borrower). The Borrower shall give notice of any such automatic reduction of
the Maximum Commitment to the Liquidity Provider within two Business Days
thereof. The failure by the Borrower to furnish any such notice shall not affect
such automatic reduction of the Maximum Commitment.

            (b) TERMINATION. Upon the making of any Provider Advance or Final
Advance hereunder or the occurrence of the Termination Date, the obligation of
the Liquidity Provider to make further Advances hereunder shall automatically
and irrevocably terminate, and the Borrower shall not be entitled to request any
further Borrowing hereunder.

            Section 2.05. REPAYMENTS OF INTEREST ADVANCES OR THE FINAL ADVANCE.
Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees,
without notice of an Advance or demand for repayment from the Liquidity Provider
(which notice and demand are hereby waived by the Borrower), to pay, or to cause
to be paid, to the Liquidity Provider on each date on which the Liquidity
Provider shall make an Interest Advance or the Final Advance, an amount equal to
(a) the amount of such Advance (any such Advance, until repaid, is referred to
herein as an "UNPAID ADVANCE"), plus (b) interest on the amount of each such
Unpaid Advance as provided in Section 3.07 hereof; PROVIDED that if (i) the
Liquidity Provider shall make a Provider Advance at any time after making one or
more Interest Advances which shall not have been repaid in accordance with this
Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility
or Non-Extended Facility at any time when unreimbursed Interest Advances have
reduced the Maximum Available Commitment to zero, then such Interest Advances
shall cease to constitute Unpaid Advances and shall be deemed to have been
changed into an Applied Downgrade Advance or an Applied Non-Extension Advance,
as the case may be, for all purposes of this Agreement (including, without
limitation, for the purpose of determining when such Interest Advance is
required to be repaid to the Liquidity Provider in accordance with Section 2.06
and for the purposes of Section 2.06(b)). The Borrower and the Liquidity
Provider agree that the repayment in full of each Interest Advance and Final
Advance on the date such Advance is made is intended to be a contemporaneous
exchange for new value given to the Borrower by the Liquidity Provider.

            Section 2.06. REPAYMENTS OF PROVIDER ADVANCES. (a) Amounts advanced
hereunder in respect of a Provider Advance shall be deposited in the Class A-2
Cash Collateral Account, invested and withdrawn from the Class A-2 Cash
Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the
Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider,
on each Regular Distribution Date, commencing on the first Regular Distribution
Date after the making of a Provider Advance, interest on the principal amount of
any such Provider Advance as provided in Section 3.07; PROVIDED, HOWEVER, that
amounts in respect of a Provider Advance withdrawn from the Class A-2 Cash
Collateral Account for the purpose of paying interest on the Class A-2
Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement
(the amount of any such withdrawal being (y) in the case of a Downgrade Advance,
an "APPLIED DOWNGRADE ADVANCE" and (z) in the case of a Non-Extension Advance,
an "APPLIED NON-EXTENSION ADVANCE" and, together with an Applied Downgrade
Advance, an "APPLIED PROVIDER ADVANCE") shall thereafter (subject to Section
2.06(b)) be treated as an Interest Advance under this Agreement for purposes of
determining the Applicable Liquidity Rate for interest payable thereon; PROVIDED
FURTHER, HOWEVER, that if, following the making of a Provider Advance, the
Liquidity Provider delivers a Termination Notice to the Borrower pursuant to
Section 6.01 hereof, such Provider Advance shall thereafter be treated as a
Final Advance under this Agreement for purposes of determining the Applicable
Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09
hereof, immediately upon the withdrawal of any amounts from the Class A-2 Cash
Collateral Account on account of a reduction in the Required Amount, the
Borrower shall repay to the Liquidity Provider a portion of the Provider
Advances in a principal amount equal to such reduction, plus interest on the
principal amount prepaid as provided in Section 3.07 hereof.

            (b) At any time when an Applied Provider Advance (or any portion
thereof) is outstanding, upon the deposit in the Class A-2 Cash Collateral
Account of any amount pursuant

                                       10
<Page>

to clause "THIRD" of Section 2.4(b) of the Intercreditor Agreement, clause
"THIRD" of Section 3.2 of the Intercreditor Agreement or clause "FOURTH" of
Section 3.3 of the Intercreditor Agreement (any such amount being a
"REPLENISHMENT AMOUNT") for the purpose of replenishing or increasing the
balance thereof up to the Required Amount at such time, (i) the aggregate
outstanding principal amount of all Applied Provider Advances (and of Provider
Advances treated as an Interest Advance for purposes of determining the
Applicable Liquidity Rate for interest payable thereon) shall be automatically
reduced by the amount of such Replenishment Amount and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances shall be
automatically increased by the amount of such Replenishment Amount.

            (c) Upon the provision of a Replacement Liquidity Facility in
replacement of this Agreement in accordance with Section 3.6(e) of the
Intercreditor Agreement, amounts remaining on deposit in the Class A-2 Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider, but only
to the extent such amounts are necessary to repay in full to the Liquidity
Provider all amounts owing to it hereunder.

            Section 2.07. PAYMENTS TO THE LIQUIDITY PROVIDER UNDER THE
INTERCREDITOR AGREEMENT. In order to provide for payment or repayment to the
Liquidity Provider of any amounts hereunder, the Intercreditor Agreement
provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the
Liquidity Provider in accordance with the terms thereof. Amounts so paid to the
Liquidity Provider shall be applied by the Liquidity Provider to Liquidity
Obligations then due and payable in accordance with the Intercreditor Agreement
or, if not provided for in the Intercreditor Agreement, then in such manner as
the Liquidity Provider shall deem appropriate.

            Section 2.08. BOOK ENTRIES. The Liquidity Provider shall maintain in
accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower resulting from Advances made from time to time and
the amounts of principal and interest payable hereunder and paid from time to
time in respect thereof; PROVIDED, HOWEVER, that the failure by the Liquidity
Provider to maintain such account or accounts shall not affect the obligations
of the Borrower in respect of Advances.

            Section 2.09. PAYMENTS FROM AVAILABLE FUNDS ONLY. All payments to be
made by the Borrower under this Agreement shall be made only from the amounts
that constitute Scheduled Payments, Special Payments or payments under Section
7(c) of the Participation Agreements and Section 7 of the Note Purchase
Agreement and only to the extent that the Borrower shall have sufficient income
or proceeds therefrom to enable the Borrower to make payments in accordance with
the terms hereof after giving effect to the priority of payments provisions set
forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will
look solely to such amounts to the extent available for distribution to it as
provided in the Intercreditor Agreement and this Agreement and that the
Borrower, in its individual capacity, is not personally liable to it for any
amounts payable or liability under this Agreement except as expressly provided
in this Agreement, the Intercreditor Agreement or any Participation Agreement.
Amounts on deposit in the Class A-2 Cash Collateral Account shall be available
to

                                       11
<Page>

the Borrower to make payments under this Agreement only to the extent and for
the purposes expressly contemplated in Section 3.6(f) of the Intercreditor
Agreement.

            Section 2.10. EXTENSION OF THE EXPIRY DATE; NON-EXTENSION ADVANCE.
The Borrower may, from time to time, by notice to the Liquidity Provider (each
such notice being an "EXTENSION NOTICE") given no later than the 40th day and no
earlier than the 60th day prior to the then applicable Expiry Date, request an
extension of the Expiry Date to the earlier of (i) the date which is 15 days
after the Final Legal Distribution Date for the Class A-2 Certificates and (ii)
the date that is the day immediately preceding the 364th day occurring after the
last day of the Consent Period (as hereinafter defined). Whether or not the
Liquidity Provider has received a request from the Borrower, such Liquidity
Provider may, but shall not be obligated to, by a notice (a "CONSENT NOTICE") to
the Borrower, given during the period commencing on the date that is 60 days
prior to the Expiry Date then in effect (or, if earlier, the date of such
Liquidity Provider's receipt of such request, if any, from the Borrower) and
ending on the date that is 25 days prior to the Expiry Date then in effect for
such Liquidity Facility (such period, with respect to such Liquidity Facility,
the "CONSENT PERIOD"), consent to such extension of the Expiry Date, which
consent may be given or withheld by the Liquidity Provider in its absolute and
sole discretion; PROVIDED, HOWEVER, that such extension shall not be effective
with respect to the Liquidity Provider if by a notice (a "WITHDRAWAL NOTICE") to
the Borrower during the Consent Period the Liquidity Provider revokes its
Consent Notice. If a Withdrawal Notice has been given during the applicable
Consent Period or if the Liquidity Provider fails irrevocably and
unconditionally to advise the Borrower on or before the date on which such
Consent Period ends that the applicable Expiry Date shall be so extended, (and,
in each case, if the Liquidity Provider shall not have been replaced in
accordance with Section 3.6(e) of the Intercreditor Agreement), the Borrower
shall be entitled on and after the date on which the Consent Period ends (but
prior to the then effective Expiry Date) to request a Non-Extension Advance in
accordance with Section 2.02(b) hereof and Section 3.6(d) of the Intercreditor
Agreement.

            Section 2.11. RIGHT TO FURTHER EXTEND EXPIRY DATE. Subject to the
proviso in the immediately succeeding sentence, the Liquidity Provider shall
have the right at any time and without the consent of the Borrower to extend the
then effective Expiry Date to the date that is 15 days after the Final Legal
Distribution Date for the Class A-2 Certificates by giving not less than five
nor more than ten days' prior written notice of such extension to the Borrower,
the Class A-2 Trustee and Northwest (which notice shall specify the effective
date of such extension (the "Extension Effective Date")). On the Extension
Effective Date, the then effective Expiry Date shall be so extended without any
further act; provided, however, that if prior to the Extension Effective Date a
Downgrade Event shall have occurred, the then effective Expiry Date shall not be
so extended.

                                   ARTICLE III

                           OBLIGATIONS OF THE BORROWER

            Section 3.01. INCREASED COSTS. If the Liquidity Provider shall
determine that (a) any change after the date hereof in any law, regulation, rule
or directive or in the interpretation

                                       12
<Page>

thereof by any court or administrative or governmental authority charged with
the administration thereof or in the compliance by the Liquidity Provider (or
its head office) with any applicable direction, request or requirement (whether
or not having the force of law) of any central bank or competent governmental or
other authority shall either (i) impose, modify or deem applicable any reserve,
special deposit or similar requirement against assets held by, or deposits in or
for the account of, or loans made by, the Liquidity Provider, or (ii) impose on
the Liquidity Provider any other condition regarding this Agreement or any
Advance, or (iii) subject the Liquidity Provider to any Taxes with respect to
amounts payable or paid or change the basis of taxation of any amounts payable
to the Liquidity Provider (other than Excluded Taxes) and (b) the result of any
event referred to in the preceding clauses (i), (ii) or (iii) shall be to
increase the cost to the Liquidity Provider of issuing or maintaining its
commitment or funding or maintaining Advances (which increase in cost shall be
determined by the Liquidity Provider's reasonable allocations of the aggregate
of such cost increases resulting from such event), then, upon demand by the
Liquidity Provider ), the Borrower shall pay, or cause to be paid, to the
Liquidity Provider, from time to time as specified by the Liquidity Provider,
additional amounts which shall be sufficient to compensate the Liquidity
Provider for such increased cost; provided that if such demand for payment is
made more than 180 days after a Responsible Officer of the Liquidity Provider
obtains actual knowledge of any event referred to in clause (i), (ii) or (iii)
above period, the Borrower shall be obligated to pay such additional amounts
only with respect to such increased cost actually incurred or effected on or
after the 180th day prior to the date of such demand. A certificate as to such
increased cost incurred by the Liquidity Provider as a result of any event
mentioned in clauses (i), (ii) or (iii) above, prepared in reasonable detail and
submitted by the Liquidity Provider to the Borrower, shall be conclusive
evidence of the amount owed under this Section, absent manifest error.

            The Liquidity Provider agrees to use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section 3.01 that
may thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.

            Section 3.02. CAPITAL ADEQUACY. If the Liquidity Provider shall
determine that the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the Liquidity Provider (or its head office) with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, in each case after the date
hereof, has the effect of reducing the rate of return on the Liquidity
Provider's capital as a consequence of issuing or maintaining its commitment
hereunder or its funding or maintaining Advances to a level below that which the
Liquidity Provider could have achieved but for such adoption, change or
compliance (taking into consideration the Liquidity Provider's policies with
respect to capital adequacy) by an amount deemed by the Liquidity Provider to be
material, then, upon demand by the Liquidity Provider, the Borrower shall pay to
the Liquidity Provider, from time to time as specified by the Liquidity
Provider, additional amounts which shall be sufficient to compensate the
Liquidity Provider for such reduction in respect of issuing or maintaining its
commitment hereunder or its funding or maintaining Advances. A certificate as to
any such additional amount describing the event

                                       13
<Page>

which has the effect of reducing the rate of return on the Liquidity Provider's
capital, prepared in reasonable detail and submitted by the Liquidity Provider
to the Borrower, shall be conclusive evidence of the amount owed under this
Section, absent manifest error.

            The Liquidity Provider agrees to use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section 3.02 that
may thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.

            Section 3.03. PAYMENTS FREE OF DEDUCTIONS. (a) All payments made by
the Borrower under this Agreement shall be made free and clear of, and without
reduction for or on account of, any present or future stamp or other taxes,
levies, imposts, duties, charges, fees, deductions, withholdings, restrictions
or conditions of any nature whatsoever now or hereafter imposed, levied,
collected, withheld or assessed, excluding Excluded Taxes (such non-excluded
taxes being referred to herein, collectively, as "Non-Excluded Taxes" and,
individually, as a "NON-EXCLUDED TAX"). If any Non-Excluded Taxes are required
to be withheld from any amounts payable to the Liquidity Provider under this
Agreement, the amounts so payable to the Liquidity Provider shall be increased
to the extent necessary to yield to the Liquidity Provider (after payment of all
Non-Excluded Taxes and taxes imposed on the receipt of such increase) interest
or any other such amounts payable under this Agreement at the rates or in the
amounts specified in this Agreement. The Liquidity Provider agrees to use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to change the jurisdiction of its Lending Office if making such
change would avoid the need for, or reduce the amount of, any such additional
amounts that may thereafter accrue and would not, in the reasonable judgment of
the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.
On or prior to the Closing Date, the Liquidity Provider agrees to provide to the
Borrower (i) two copies of a properly completed United States Internal Revenue
Service Form W-8BEN or Form W-8ECI, as appropriate, or other applicable form,
certificate or document prescribed by the Internal Revenue Service certifying,
in each case, the Liquidity Provider's entitlement to a complete exemption from
United States federal withholding tax in respect to any and all payments to be
made hereunder, and (ii) agree to provide the Borrower a new Form W-8BEN or Form
W-8ECI, as appropriate, (A) on or before the date that any such form expires or
becomes obsolete or (B) after the occurrence of any event requiring a change in
the most recent form previously delivered by it and prior to the immediately
following due date of any payment by the Borrower hereunder, certifying in the
case of a Form W-8ECI or Form W-8BEN that the Liquidity Provider is exempt from
or entitled to a reduced rate of United States federal withholding tax on
payments under this Agreement.

            (b) All payments (including, without limitation, Advances) made by
the Liquidity Provider under this Agreement shall be made free and clear of, and
without reduction for or on account of, any Taxes. If any Taxes are required to
be withheld or deducted from any amounts payable to the Borrower under this
Agreement, the Liquidity Provider shall (i) within the time prescribed therefor
by applicable law pay to the appropriate governmental or taxing authority the
full amount of any such Taxes (and any additional Taxes in respect of the
payment required under clause (ii) hereof) and make such reports or returns in
connection therewith at the time or times and in the manner prescribed by
applicable law, and (ii) pay to the Borrower an additional

amount which (after deduction of all such Taxes) will be sufficient to yield to
the Borrower the full amount which would have been received by it had no such
withholding or deduction been made. Within 30 days after the date of each
payment hereunder, the Liquidity Provider shall furnish to the Borrower the
original or a certified copy of (or other documentary evidence of) the payment
of the Taxes applicable to such payment.

            (c) If any exemption from, or reduction in the rate of, any Taxes is
reasonably available to the Borrower to establish that payments under this
Agreement are exempt from (or entitled to a reduced rate of) tax, the Borrower
shall deliver to the Liquidity Provider such form or forms and such other
evidence of the eligibility of the Borrower for such exemption or reduction as
the Liquidity Provider may reasonably identify to the Borrower as being required
as a condition to exemption from, or reduction in the rate of, any Taxes.

            Section 3.04. PAYMENTS. The Borrower shall make or cause to be made
each payment to the Liquidity Provider under this Agreement so as to cause the
same to be received by the Liquidity Provider not later than 1:00 P.M. (New York
City time) on the day when due. The Borrower shall make all such payments in
lawful money of the United States of America, to the Liquidity Provider in
immediately available funds, by wire transfer to Citibank N.A., New York, ABA #
021000089, Account No. 10920118, Reference: Northwest Airlines EETC 2001-1A-2
#4187936, Attention: M. Kirr MT215000.

            Section 3.05. COMPUTATIONS. All computations of interest based on
the Base Rate shall be made on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the LIBOR Rate shall be
made on the basis of a year of 360 days, in each case for the actual number of
days (including the first day but excluding the last day) occurring in the
period for which such interest is payable.

            Section 3.06. PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to
be made hereunder shall be stated to be due on a day other than a Business Day,
such payment shall be made on the next succeeding Business Day and no additional
interest shall be due as a result (and if so made, shall be deemed to have been
made when due). If any payment in respect of interest on an Advance is so
deferred to the next succeeding Business Day, such deferral shall not delay the
commencement of the next Interest Period for such Advance (if such Advance is a
LIBOR Advance) or reduce the number of days for which interest will be payable
on such Advance on the next interest payment date for such Advance.

            Section 3.07. INTEREST. (a) Subject to Section 2.09, the Borrower
shall pay, or shall cause to be paid, without duplication, interest on (i) the
unpaid principal amount of each Advance from and including the date of such
Advance (or, in the case of an Applied Provider Advance, from and including the
date on which the amount thereof was withdrawn from the Class A-2 Cash
Collateral Account to pay interest on the Class A-2 Certificates) to but
excluding the date such principal amount shall be paid in full (or, in the case
of an Applied Provider Advance, the date on which the Class A-2 Cash Collateral
Account is fully replenished in respect of such Advance) and (ii) any other
amount due hereunder (whether fees, commissions, expenses or other amounts or,
to the extent permitted by law, installments of interest on Advances or any such
other amount) which is not paid when due (whether at stated maturity, by
acceleration or otherwise) from and including the due date thereof to but
excluding the date such amount is paid

                                       15
<Page>

in full, in each such case, at a fluctuating interest rate per annum for each
day equal to the Applicable Liquidity Rate (as defined below) for such Advance
or such other amount as in effect for such day, but in no event at a rate per
annum greater than the maximum rate permitted by applicable law; PROVIDED,
HOWEVER, that, if at any time the otherwise applicable interest rate as set
forth in this Section 3.07 shall exceed the maximum rate permitted by applicable
law, then any subsequent reduction in such interest rate will not reduce the
rate of interest payable pursuant to this Section 3.07 below the maximum rate
permitted by applicable law until the total amount of interest accrued equals
the amount of interest that would have accrued if such otherwise applicable
interest rate as set forth in this Section 3.07 had at all times been in effect.

            (b) Each Advance (other than any Unapplied Non-Extension Advance)
will be either a Base Rate Advance or a LIBOR Advance as provided in this
Section. Each such Advance will be a Base Rate Advance for the period from the
date of its borrowing to (but excluding) the third Business Day following the
Liquidity Provider's receipt of the Notice of Borrowing for such Advance.
Thereafter, such Advance shall be a LIBOR Advance; PROVIDED that (i) an Applied
Provider Advance (other than an Unapplied Non-Extension Advance) shall always be
a LIBOR Advance unless the Borrower elects otherwise and (ii) the Borrower (at
the direction of the Controlling Party, so long as the Liquidity Provider is not
the Controlling Party) may (x) convert the Final Advance into a Base Rate
Advance on the last day of an Interest Period for such Advance by giving the
Liquidity Provider no less than four Business Days' prior written notice of such
election or (y) elect to maintain the Final Advance as a Base Rate Advance by
not requesting a conversion of the Final Advance to a LIBOR Advance under Clause
(5) of the applicable Notice of Borrowing (or, if such Final Advance is deemed
to have been made, without delivery of a Notice of Borrowing pursuant to Section
2.06, by requesting, prior to 11:00 A.M. (New York City time) on the first
Business Day immediately following the Borrower's receipt of the applicable
Termination Notice, that such Final Advance not be converted from a Base Rate
Advance to a LIBOR Advance).

            (c) Each LIBOR Advance shall bear interest during each Interest
Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus
the Applicable Margin for such LIBOR Advance, payable in arrears on the last day
of such Interest Period and, in the event of the payment of principal of such
LIBOR Advance on a day other than such last day, on the date of such payment (to
the extent of interest accrued on the amount of principal repaid).

            (d) Each Base Rate Advance shall bear interest at a rate per annum
equal to the Base Rate plus the Applicable Margin for such Base Rate Advance,
payable in arrears on each Regular Distribution Date and, in the event of the
payment of principal of such Base Rate Advance on a day other than a Regular
Distribution Date, on the date of such payment (to the extent of interest
accrued on the amount of principal repaid).

            (e) Each Unapplied Non-Extension Advance shall bear interest in an
amount equal to the Investment Earnings on amounts on deposit in the Class A-2
Cash Collateral Account plus the Applicable Margin for such Unapplied
Non-Extension Advance on the amount of such Unapplied Non-Extension Advance from
time to time, payable in arrears on each Distribution Date.

                                       16
<Page>

            (f) Each amount not paid when due hereunder (whether fees,
commissions, expenses or other amounts or, to the extent permitted by applicable
law, installments of interest on Advances but excluding Advances) shall bear
interest at a rate per annum equal to the Base Rate plus 2.0% until paid.

            (g) Each change in the Base Rate shall become effective immediately.
The rates of interest specified in this Section 3.07 with respect to any Advance
or other amount shall be referred to as the "APPLICABLE LIQUIDITY RATE".

            Section 3.08. REPLACEMENT OF BORROWER. From time to time and subject
to the successor Borrower's meeting the eligibility requirements set forth in
Section 6.9 of the Intercreditor Agreement applicable to the Subordination
Agent, upon the effective date and time specified in a written and completed
Notice of Replacement Subordination Agent in substantially the form of Annex VI
attached hereto (a "NOTICE OF REPLACEMENT SUBORDINATION AGENT") delivered to the
Liquidity Provider by the then Borrower, the successor Borrower designated
therein shall be substituted for as the Borrower for all purposes hereunder.

            Section 3.09. FUNDING LOSS INDEMNIFICATION. The Borrower shall pay
to the Liquidity Provider, upon the request of the Liquidity Provider, such
amount or amounts as shall be sufficient (in the reasonable opinion of the
Liquidity Provider) to compensate it for any loss, cost, or expense incurred as
a result of:

                  (1) Any repayment of a LIBOR Advance on a date other than the
            last day of the Interest Period for such Advance; or

                  (2) Any failure by the Borrower to borrow a LIBOR Advance on
            the date for borrowing specified in the relevant notice under
            Section 2.02.

            Section 3.10. ILLEGALITY. Notwithstanding any other provision in
this Agreement, if any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Liquidity Provider (or its Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful
or impossible for the Liquidity Provider (or its Lending Office) to maintain or
fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity
Provider, the outstanding principal amount of the LIBOR Advances shall be
converted to Base Rate Advances (a) immediately upon demand of the Liquidity
Provider, if such change or compliance with such request, in the judgment of the
Liquidity Provider, requires immediate repayment; or (b) at the expiration of
the last Interest Period to expire before the effective date of any such change
or request.

            (b) Neither the Liquidity Provider nor any of its officers,
employees, directors or affiliates shall be liable or responsible in any respect
for (i) any error, omission, interruption or delay in transmission, dispatch or
delivery of any message or advice, however transmitted, in connection with this
Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action,
inaction or omission which may be taken by it in good faith, absent willful
misconduct or negligence (in which event the extent of the Liquidity Provider's
potential liability to the Borrower shall be limited as set forth in the
immediately preceding paragraph), in connection with this Agreement or any
Notice of Borrowing.

            Section 7.07. COSTS, EXPENSES AND TAXES. The Borrower agrees to pay,
or cause to be paid (A) on the Effective Date and on such later date or dates on
which the Liquidity Provider shall make demand, all reasonable out-of-pocket
costs and expenses (including, without limitation, the reasonable fees and
expenses of outside counsel for the Liquidity Provider) of the Liquidity
Provider in connection with the preparation, negotiation, execution, delivery,
filing and recording of this Agreement, any other Operative Agreement and any
other documents which may be delivered in connection with this Agreement and (B)
on demand, all reasonable costs and expenses (including reasonable counsel fees
and expenses) of the Liquidity Provider in connection with (i) the enforcement
of this Agreement or any other Operative Agreement, (ii) the modification or
amendment of, or supplement to, this Agreement or any other Operative Agreement
or such other documents which may be delivered in connection herewith or
therewith (whether or not the same shall become effective) or (iii) any action
or proceeding relating to any order, injunction, or other process or decree
restraining or seeking to restrain the Liquidity Provider from paying any amount
under this Agreement, the Intercreditor Agreement or any other Operative
Agreement or otherwise affecting the application of funds in the Class A-2 Cash
Collateral Account. In addition, the Borrower shall pay any and all recording,
stamp and other similar taxes and fees payable or determined to be payable in
connection with the execution, delivery, filing and recording of this Agreement,
any other Operative Agreement and such other documents, and agrees to save the
Liquidity Provider harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such taxes
or fees.

            Section 7.08. BINDING EFFECT; PARTICIPATIONS. (a) This Agreement
shall be binding upon and inure to the benefit of the Borrower and the Liquidity
Provider and their respective successors and assigns, except that neither the
Liquidity Provider (except as otherwise provided in this Section 7.08) nor
(except as contemplated by Section 3.08) the Borrower shall have the right to
assign its rights or obligations hereunder or any interest herein without the
prior written consent of the other party, subject to the requirements of Section
7.08(b). The Liquidity Provider may grant participations herein or in any of its
rights hereunder (including, without limitation, funded participations and
participations in rights to receive interest payments hereunder) and under the
other Operative Agreements to such Persons as the Liquidity Provider may in its
sole discretion select (but excluding Northwest and any of its Affiliates),
subject to the requirements of Section 7.08(b). No such granting of
participations by the Liquidity Provider, however, will relieve the Liquidity
Provider of its obligations hereunder. In connection with any participation or
any proposed participation, the Liquidity Provider may disclose to the
participant or the proposed participant any information that the Borrower is
required to deliver or to disclose to the Liquidity Provider pursuant to this
Agreement. The Borrower acknowledges and agrees that the Liquidity Provider's
source of funds may derive in part from its participants.

                                       23
<Page>

Accordingly, references in this Agreement and the other Operative Agreements to
determinations, reserve and capital adequacy requirements, increased costs,
reduced receipts, additional amounts due pursuant to Section 3.03 and the like
as they pertain to the Liquidity Provider shall be deemed also to include those
of each of its participants (subject, in each case, to the maximum amount that
would have been incurred by or attributable to the Liquidity Provider directly
if the Liquidity Provider, rather than the participant, had held the interest
participated).

            (b) If, pursuant to subsection (a) above, the Liquidity Provider
sells any participation in this Agreement to any bank or other entity (each, a
"TRANSFEREE"), then, concurrently with the effectiveness of such participation,
the Transferee shall (i) represent to the Liquidity Provider (for the benefit of
the Liquidity Provider and the Borrower) either (A) that it is incorporated
under the laws of the United States or a state thereof or (B) that under
applicable law and treaties, no taxes will be required to be withheld with
respect to any payments to be made to such Transferee in respect of this
Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a
statement that it is incorporated under the laws of the United States or a state
thereof or (y) if it is not so incorporated, two copies of a properly completed
United States Internal Revenue Service Form W-8BEN or Form W-8ECI, as
appropriate, or other applicable form, certificate or document prescribed by the
Internal Revenue Service certifying, in each case, such Transferee's entitlement
to a complete exemption from United States federal withholding tax in respect to
any and all payments to be made hereunder, and (iii) agree (for the benefit of
the Liquidity Provider and the Borrower) to provide the Liquidity Provider and
the Borrower a new Form W-8BEN or Form W-8ECI, as appropriate, (A) on or before
the date that any such form expires or becomes obsolete or (B) after the
occurrence of any event requiring a change in the most recent form previously
delivered by it and prior to the immediately following due date of any payment
by the Borrower hereunder, certifying in the case of a Form W-8ECI or Form
W-8BEN that such Transferee is entitled to a complete exemption from United
States federal withholding tax on payments under this Agreement. Unless the
Borrower has received forms or other documents reasonably satisfactory to it
(and required by applicable law) indicating that payments hereunder are not
subject to United States federal withholding tax, the Borrower will withhold
taxes as required by law from such payments at the applicable statutory rate.

            (c) Notwithstanding the other provisions of this Section 7.08, the
Liquidity Provider may assign and pledge all or any portion of the Advances
owing to it to any Federal Reserve Bank or the United States Treasury as
collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank, provided that any payment in respect of such assigned Advances made by the
Borrower to the Liquidity Provider in accordance with the terms of this
Agreement shall satisfy the Borrower's obligations hereunder in respect of such
assigned Advance to the extent of such payment. No such assignment shall release
the Liquidity Provider from its obligations hereunder.

            Section 7.09. SEVERABILITY. Any provision of this Agreement which is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or non-authorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

            inconvenient court and agrees not to plead or claim the same;

                  (iii) agrees that service of process in any such action or

            Provider shall have been notified pursuant thereto; and

                  (iv) agrees that nothing herein shall affect the right to
            effect service of process in any other manner permitted by law or
            shall limit the right to sue in any other jurisdiction.

            (b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO

voluntarily waives its jury trial rights following consultation with such legal
counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN
WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,

irrevocably agrees, on the terms and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the period
from the Effective Date until 1:00 P.M. (New York City time) on the Expiry Date
(unless the obligations of the Liquidity Provider shall be earlier terminated in
accordance with the terms of Section 2.04(b)) in an aggregate amount at any time
outstanding not to exceed the Maximum Commitment.

                  Section 2.02. MAKING THE ADVANCES. (a) Interest Advances shall
be made in one or more Borrowings by delivery to the Liquidity Provider of one
or more written and completed Notices of Borrowing in substantially the form of
Annex I attached hereto, signed by a Responsible Officer of the Borrower, in an
amount not exceeding the Maximum Available Commitment at such time and shall be
used solely for the payment when due of interest on the Class B Certificates at
the Stated Interest Rate therefor in accordance with Section 3.6(a) of the
Intercreditor Agreement. Each Interest Advance made hereunder shall
automatically reduce the Maximum Available Commitment and the amount available
to be borrowed hereunder by subsequent Advances by the amount of such Interest
Advance (subject to reinstatement as provided in the next sentence). Upon
repayment to the Liquidity Provider in full of the amount of any Interest
Advance made pursuant to this Section 2.02(a), together with accrued interest
thereon (as provided herein), the Maximum Available Commitment shall be
reinstated by the amount of such repaid Interest Advance, but not to exceed the
Maximum Commitment; PROVIDED, HOWEVER, that the Maximum Available Commitment
shall not be so reinstated at any

                                       7

time if (i) a Liquidity Event of Default shall have occurred and be continuing
and (ii) there is a Performing Note Deficiency.

                  (b) A Non-Extension Advance shall be made in a single
Borrowing if this Agreement is not extended in accordance with Section 3.6(d) of
the Intercreditor Agreement (unless a Replacement Liquidity Facility to replace
this Agreement shall have been delivered to the Borrower as contemplated by said
Section 3.6(d) within the time period specified in such Section) by delivery to
the Liquidity Provider of a written and completed Notice of Borrowing in
substantially the form of Annex II attached hereto, signed by a Responsible
Officer of the Borrower, in an amount equal to the Maximum Available Commitment
at such time, and shall be used to fund the Class B Cash Collateral Account in
accordance with said Section 3.6(d) and Section 3.6(f) of the Intercreditor
Agreement.

                  (c) A Downgrade Advance shall be made in a single Borrowing
upon the occurrence of a Downgrade Event (as provided for in Section 3.6(c) of
the Intercreditor Agreement) unless a Replacement Liquidity Facility to replace
this Agreement shall have been previously delivered to the Borrower in
accordance with said Section 3.6(c), by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of Annex III
attached hereto, signed by a Responsible Officer of the Borrower, in an amount
equal to the Maximum Available Commitment at the time of such borrowing, and
shall be used to fund the Class B Cash Collateral Account in accordance with
said Section 3.6(c) and Section 3.6(f) of the Intercreditor Agreement.

                  (d) A Final Advance shall be made in a single Borrowing upon
the receipt by the Borrower of a Termination Notice from the Liquidity Provider
pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of Annex IV
attached hereto, signed by a Responsible Officer of the Borrower, in an amount
equal to the Maximum Available Commitment at such time, and shall be used to
fund the Class B Cash Collateral Account in accordance with Section 3.6(i) and
Section 3.6(f) of the Intercreditor Agreement.

                  (e) Each Borrowing shall be made on notice in writing (a
"NOTICE OF BORROWING") in substantially the form required by Section 2.02(a),
2.02(b), 2.02(c) or 2.02(d), as the case may be, given by the Borrower to the
Liquidity Provider. If a Notice of Borrowing is delivered by the Borrower in
respect of any Borrowing no later than 1:00 p.m. (New York City time) on a
Business Day, upon satisfaction of the conditions precedent set forth in Section
4.02 with respect to a requested Borrowing, the Liquidity Provider shall make
available to the Borrower, in accordance with its payment instructions, the
amount of such Borrowing in U.S. dollars and immediately available funds, before
4:00 p.m. (New York City time) on such Business Day or on such later Business
Day specified in such Notice of Borrowing. If a Notice of Borrowing is delivered
by the Borrower in respect of any Borrowing after 1:00 p.m. (New York City time)
on a Business Day, upon satisfaction of the conditions precedent set forth in
Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall
make available to the Borrower, in accordance with its payment instructions, the
amount of such Borrowing in U.S. dollars and immediately available funds, before
12:00 Noon (New York City time) on the first Business Day next following the day
of receipt of such Notice of Borrowing or on such later Business Day specified
by the Borrower in such Notice of Borrowing. Payments of proceeds of a Borrowing

                                       8
<Page>

shall be made by wire transfer of immediately available funds to the Borrower in
accordance with such wire transfer instructions as the Borrower shall furnish
from time to time to the Liquidity Provider for such purpose. Each Notice of
Borrowing shall be irrevocable and binding on the Borrower. Each Notice of
Borrowing shall be effective upon delivery of a copy thereof to the Liquidity
Provider's New York Branch at the address specified in Section 7.02 hereof.

                  (f) Upon the making of any Advance requested pursuant to a
Notice of Borrowing, in accordance with the Borrower's payment instructions, the
Liquidity Provider shall be fully discharged of its obligation hereunder with
respect to such Notice of Borrowing, and the Liquidity Provider shall not
thereafter be obligated to make any further Advances hereunder in respect of
such Notice of Borrowing to the Borrower or to any other Person. If the
Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing
before 12:00 Noon (New York City time) on the second Business Day after the date
of payment specified in said Section 2.02(e), the Liquidity Provider shall have
fully discharged its obligations hereunder with respect to such Advance and an
event of default shall not have occurred hereunder. Following the making of any
Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the Class B Cash
Collateral Account, the Liquidity Provider shall have no interest in or rights
to the Class B Cash Collateral Account, the funds constituting such Advance or
any other amounts from time to time on deposit in the Class B Cash Collateral
Account; PROVIDED that the foregoing shall not affect or impair the obligations
of the Subordination Agent to make the distributions contemplated by Section
3.6(e) or (f) of the Intercreditor Agreement and provided further, that the
foregoing shall not affect or impair the rights of the Liquidity Provider to
provide written instructions with respect to the investment and reinvestment of
amounts in the Cash Collateral Accounts to the extent provided in Section 2.2(b)
of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances
requested by the Borrower in accordance with the provisions of this Agreement,
the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the amount
of the Advances so made and requested.

                  Section 2.03. FEES. The Borrower agrees to pay to the
Liquidity Provider the fees set forth in the Fee Letter applicable to this
Agreement.

                  Section 2.04. REDUCTION OR TERMINATION OF THE MAXIMUM
COMMITMENT.

                  (a) AUTOMATIC REDUCTION. Promptly following each date on which
the Required Amount is reduced as a result of a reduction in the Pool Balance of
the Class B Certificates or otherwise, the Maximum Commitment shall
automatically be reduced to an amount equal to such reduced Required Amount (as
calculated by the Borrower). The Borrower shall give notice of any such
automatic reduction of the Maximum Commitment to the Liquidity Provider within
two Business Days thereof. The failure by the Borrower to furnish any such
notice shall not affect such automatic reduction of the Maximum Commitment.

                  (b) TERMINATION. Upon the making of any Provider Advance or
Final Advance hereunder or the occurrence of the Termination Date, the
obligation of the Liquidity Provider to make further Advances hereunder shall
automatically and irrevocably terminate, and the Borrower shall not be entitled
to request any further Borrowing hereunder.

                  Section 2.05. REPAYMENTS OF INTEREST ADVANCES OR THE FINAL
ADVANCE. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby
agrees, without notice of an Advance or demand for repayment from the Liquidity
Provider (which notice and demand are hereby waived by the Borrower), to pay, or
to cause to be paid, to the Liquidity Provider on each date on which the
Liquidity Provider shall make an Interest Advance or the Final Advance, an
amount equal to (a) the amount of such Advance (any such Advance, until repaid,
is referred to herein as an "UNPAID ADVANCE"), plus (b) interest on the amount
of each such Unpaid Advance as provided in Section 3.07 hereof; PROVIDED that if
(i) the Liquidity Provider shall make a Provider Advance at any time after
making one or more Interest Advances which shall not have been repaid in
accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a
Downgraded Facility or Non-Extended Facility at any time when unreimbursed
Interest Advances have reduced the Maximum Available Commitment to zero, then
such Interest Advances shall cease to constitute Unpaid Advances and shall be
deemed to have been changed into an Applied Downgrade Advance or an Applied
Non-Extension Advance, as the case may be, for all purposes of this Agreement
(including, without limitation, for the purpose of determining when such
Interest Advance is required to be repaid to the Liquidity Provider in
accordance with Section 2.06 and for the purposes of Section 2.06(b)). The
Borrower and the Liquidity Provider agree that the repayment in full of each
Interest Advance and Final Advance on the date such Advance is made is intended
to be a contemporaneous exchange for new value given to the Borrower by the
Liquidity Provider.

                  Section 2.06. REPAYMENTS OF PROVIDER ADVANCES. (a) Amounts
advanced hereunder in respect of a Provider Advance shall be deposited in the
Class B Cash Collateral Account, invested and withdrawn from the Class B Cash
Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the
Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider,
on each Regular Distribution Date, commencing on the first Regular Distribution
Date after the making of a Provider Advance, interest on the principal amount of
any such Provider Advance as provided in Section 3.07; PROVIDED, HOWEVER, that
amounts in respect of a Provider Advance withdrawn from the Class B Cash
Collateral Account for the purpose of paying interest on the Class B
Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement
(the amount of any such withdrawal being (y) in the case of a Downgrade Advance,
an "APPLIED DOWNGRADE ADVANCE" and (z) in the case of a Non-Extension Advance,
an "APPLIED NON-EXTENSION ADVANCE" and, together with an Applied Downgrade
Advance, an "APPLIED PROVIDER ADVANCE") shall thereafter (subject to Section
2.06(b)) be treated as an Interest Advance under this Agreement for purposes of
determining the Applicable Liquidity Rate for interest payable thereon; PROVIDED
FURTHER, HOWEVER, that if, following the making of a Provider Advance, the
Liquidity Provider delivers a Termination Notice to the Borrower pursuant to
Section 6.01 hereof, such Provider Advance shall thereafter be treated as a
Final Advance under this Agreement for purposes of determining the Applicable
Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09
hereof, immediately upon the withdrawal of any amounts from the Class B Cash
Collateral Account on account of a reduction in the Required Amount, the
Borrower shall repay to the Liquidity Provider a portion of the Provider
Advances in a principal amount equal to such reduction, plus interest on the
principal amount prepaid as provided in Section 3.07 hereof.

                  (b) At any time when an Applied Provider Advance (or any
portion thereof) is outstanding, upon the deposit in the Class B Cash Collateral
Account of any amount pursuant to

                                       10
<Page>

clause "THIRD" of Section 2.4(b) of the Intercreditor Agreement, clause "THIRD"
of Section 3.2 of the Intercreditor Agreement or clause "FOURTH" of Section 3.3
of the Intercreditor Agreement (any such amount being a "REPLENISHMENT AMOUNT")
for the purpose of replenishing or increasing the balance thereof up to the
Required Amount at such time, (i) the aggregate outstanding principal amount of
all Applied Provider Advances (and of Provider Advances treated as an Interest
Advance for purposes of determining the Applicable Liquidity Rate for interest
payable thereon) shall be automatically reduced by the amount of such
Replenishment Amount and (ii) the aggregate outstanding principal amount of all
Unapplied Provider Advances shall be automatically increased by the amount of
such Replenishment Amount.

                  (c) Upon the provision of a Replacement Liquidity Facility in
replacement of this Agreement in accordance with Section 3.6(e) of the
Intercreditor Agreement, amounts remaining on deposit in the Class B Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider, but only
to the extent such amounts are necessary to repay in full to the Liquidity
Provider all amounts owing to it hereunder.

                  Section 2.07. PAYMENTS TO THE LIQUIDITY PROVIDER UNDER THE
INTERCREDITOR AGREEMENT. In order to provide for payment or repayment to the
Liquidity Provider of any amounts hereunder, the Intercreditor Agreement
provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the
Liquidity Provider in accordance with the terms thereof. Amounts so paid to the
Liquidity Provider shall be applied by the Liquidity Provider to Liquidity
Obligations then due and payable in accordance with the Intercreditor Agreement
or, if not provided for in the Intercreditor Agreement, then in such manner as
the Liquidity Provider shall deem appropriate.

                  Section 2.08. BOOK ENTRIES. The Liquidity Provider shall
maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of the Borrower resulting from Advances made from time to time
and the amounts of principal and interest payable hereunder and paid from time
to time in respect thereof; PROVIDED, HOWEVER, that the failure by the Liquidity
Provider to maintain such account or accounts shall not affect the obligations
of the Borrower in respect of Advances.

                  Section 2.09. PAYMENTS FROM AVAILABLE FUNDS ONLY. All payments
to be made by the Borrower under this Agreement shall be made only from the
amounts that constitute Scheduled Payments, Special Payments or payments under
Section 7(c) of the Participation Agreements and Section 7 of the Note Purchase
Agreement and only to the extent that the Borrower shall have sufficient income
or proceeds therefrom to enable the Borrower to make payments in accordance with
the terms hereof after giving effect to the priority of payments provisions set
forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will
look solely to such amounts to the extent available for distribution to it as
provided in the Intercreditor Agreement and this Agreement and that the
Borrower, in its individual capacity, is not personally liable to it for any
amounts payable or liability under this Agreement except as expressly provided
in this Agreement, the Intercreditor Agreement or any Participation Agreement.
Amounts on deposit in the Class B Cash Collateral Account shall be available to
the

                                       11
<Page>

Borrower to make payments under this Agreement only to the extent and for the
purposes expressly contemplated in Section 3.6(f) of the Intercreditor
Agreement.

                  Section 2.10. EXTENSION OF THE EXPIRY DATE; NON-EXTENSION
ADVANCE. The Borrower may, from time to time, by notice to the Liquidity
Provider (each such notice being an "EXTENSION NOTICE") given no later than the
40th day and no earlier than the 60th day prior to the then applicable Expiry
Date, request an extension of the Expiry Date to the earlier of (i) the date
which is 15 days after the Final Legal Distribution Date for the Class B
Certificates and (ii) the date that is the day immediately preceding the 364th
day occurring after the last day of the Consent Period (as hereinafter defined).
Whether or not the Liquidity Provider has received a request from the Borrower,
such Liquidity Provider may, but shall not be obligated to, by a notice (a
"CONSENT NOTICE") to the Borrower, given during the period commencing on the
date that is 60 days prior to the Expiry Date then in effect (or, if earlier,
the date of such Liquidity Provider's receipt of such request, if any, from the
Borrower) and ending on the date that is 25 days prior to the Expiry Date then
in effect for such Liquidity Facility (such period, with respect to such
Liquidity Facility, the "CONSENT PERIOD"), consent to such extension of the
Expiry Date, which consent may be given or withheld by the Liquidity Provider in
its absolute and sole discretion; PROVIDED, HOWEVER, that such extension shall
not be effective with respect to the Liquidity Provider if by a notice (a
"WITHDRAWAL NOTICE:) to the Borrower during the Consent Period the Liquidity
Provider revokes its Consent Notice. If a Withdrawal Notice has been given
during the applicable Consent Period or if the Liquidity Provider fails
irrevocably and unconditionally to advise the Borrower on or before the date on
which such Consent Period ends that the applicable Expiry Date shall be so
extended, (and, in each case, if the Liquidity Provider shall not have been
replaced in accordance with Section 3.6(e) of the Intercreditor Agreement), the
Borrower shall be entitled on and after the date on which the Consent Period
ends (but prior to the then effective Expiry Date) to request a Non-Extension
Advance in accordance with Section 2.02(b) hereof and Section 3.6(d) of the
Intercreditor Agreement.

                  Section 2.11. RIGHT TO FURTHER EXTEND EXPIRY DATE. Subject to
the proviso in the immediately succeeding sentence, the Liquidity Provider shall
have the right at any time and without the consent of the Borrower to extend the
then effective Expiry Date to the date that is 15 days after the Final Legal
Distribution Date for the Class B Certificates by giving not less than five nor
more than ten days' prior written notice of such extension to the Borrower, the
Class B Trustee and Northwest (which notice shall specify the effective date of
such extension (the "Extension Effective Date")). On the Extension Effective
Date, the then effective Expiry Date shall be so extended without any further
act; provided, however, that if prior to the Extension Effective Date a
Downgrade Event shall have occurred, the then effective Expiry Date shall not be
so extended.

                                   ARTICLE III

                           OBLIGATIONS OF THE BORROWER

                  Section 3.01. INCREASED COSTS. If the Liquidity Provider shall
determine that (a) any change after the date hereof in any law, regulation, rule
or directive or in the interpretation

                                       12
<Page>

thereof by any court or administrative or governmental authority charged with
the administration thereof or in the compliance by the Liquidity Provider (or
its head office) with any applicable direction, request or requirement (whether
or not having the force of law) of any central bank or competent governmental or
other authority shall either (i) impose, modify or deem applicable any reserve,
special deposit or similar requirement against assets held by, or deposits in or
for the account of, or loans made by, the Liquidity Provider, or (ii) impose on
the Liquidity Provider any other condition regarding this Agreement or any
Advance, or (iii) subject the Liquidity Provider to any Taxes with respect to
amounts payable or paid or change the basis of taxation of any amounts payable
to the Liquidity Provider (other than Excluded Taxes) and (b) the result of any
event referred to in the preceding clauses (i), (ii) or (iii) shall be to
increase the cost to the Liquidity Provider of issuing or maintaining its
commitment or funding or maintaining Advances (which increase in cost shall be
determined by the Liquidity Provider's reasonable allocations of the aggregate
of such cost increases resulting from such event), then, upon demand by the
Liquidity Provider ), the Borrower shall pay, or cause to be paid, to the
Liquidity Provider, from time to time as specified by the Liquidity Provider,
additional amounts which shall be sufficient to compensate the Liquidity
Provider for such increased cost; provided that if such demand for payment is
made more than 180 days after a Responsible Officer of the Liquidity Provider
obtains actual knowledge of any event referred to in clause (i), (ii) or (iii)
above period, the Borrower shall be obligated to pay such additional amounts
only with respect to such increased cost actually incurred or effected on or
after the 180th day prior to the date of such demand. A certificate as to such
increased cost incurred by the Liquidity Provider as a result of any event
mentioned in clauses (i), (ii) or (iii) above, prepared in reasonable detail and
submitted by the Liquidity Provider to the Borrower, shall be conclusive
evidence of the amount owed under this Section, absent manifest error.

                  The Liquidity Provider agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Lending Office if making such change would avoid
the need for, or reduce the amount of, any amount payable under this Section
3.01 that may thereafter accrue and would not, in the reasonable judgment of the
Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

                  Section 3.02. CAPITAL ADEQUACY. If the Liquidity Provider
shall determine that the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Liquidity Provider (or its head office) with any
request or directive regarding capital adequacy (whether or not having the force
of law) of any such authority, central bank or comparable agency, in each case
after the date hereof, has the effect of reducing the rate of return on the
Liquidity Provider's capital as a consequence of issuing or maintaining its
commitment hereunder or its funding or maintaining Advances to a level below
that which the Liquidity Provider could have achieved but for such adoption,
change or compliance (taking into consideration the Liquidity Provider's
policies with respect to capital adequacy) by an amount deemed by the Liquidity
Provider to be material, then, upon demand by the Liquidity Provider, the
Borrower shall pay to the Liquidity Provider, from time to time as specified by
the Liquidity Provider, additional amounts which shall be sufficient to
compensate the Liquidity Provider for such reduction in respect of issuing or
maintaining its commitment hereunder or its funding or maintaining Advances. A
certificate as to any such additional amount describing the event

                                       13
<Page>

which has the effect of reducing the rate of return on the Liquidity Provider's
capital, prepared in reasonable detail and submitted by the Liquidity Provider
to the Borrower, shall be conclusive evidence of the amount owed under this
Section, absent manifest error.

                  The Liquidity Provider agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Lending Office if making such change would avoid
the need for, or reduce the amount of, any amount payable under this Section
3.02 that may thereafter accrue and would not, in the reasonable judgment of the
Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

                  Section 3.03. PAYMENTS FREE OF DEDUCTIONS. (a) All payments
made by the Borrower under this Agreement shall be made free and clear of, and
without reduction for or on account of, any present or future stamp or other
taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
restrictions or conditions of any nature whatsoever now or hereafter imposed,
levied, collected, withheld or assessed, excluding Excluded Taxes (such
non-excluded taxes being referred to herein, collectively, as "Non-Excluded
Taxes" and, individually, as a "NON-EXCLUDED TAX"). If any Non-Excluded Taxes
are required to be withheld from any amounts payable to the Liquidity Provider
under this Agreement, the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after
payment of all Non-Excluded Taxes and taxes imposed on the receipt of such
increase) interest or any other such amounts payable under this Agreement at the
rates or in the amounts specified in this Agreement. The Liquidity Provider
agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to change the jurisdiction of its Lending Office if
making such change would avoid the need for, or reduce the amount of, any such
additional amounts that may thereafter accrue and would not, in the reasonable
judgment of the Liquidity Provider, be otherwise disadvantageous to the
Liquidity Provider. On or prior to the Closing Date, the Liquidity Provider
agrees to provide to the Borrower (i) two copies of a properly completed United
States Internal Revenue Service Form W-8BEN or Form W-8ECI, as appropriate, or
other applicable form, certificate or document prescribed by the Internal
Revenue Service certifying, in each case, the Liquidity Provider's entitlement
to a complete exemption from United States federal withholding tax in respect to
any and all payments to be made hereunder, and (ii) agree to provide the
Borrower a new Form W-8BEN or Form W-8ECI, as appropriate, (A) on or before the
date that any such form expires or becomes obsolete or (B) after the occurrence
of any event requiring a change in the most recent form previously delivered by
it and prior to the immediately following due date of any payment by the
Borrower hereunder, certifying in the case of a Form W-8ECI or Form W-8BEN that
the Liquidity Provider is exempt from or entitled to a reduced rate of United
States federal withholding tax on payments under this Agreement.

                  (b) All payments (including, without limitation, Advances)
made by the Liquidity Provider under this Agreement shall be made free and clear
of, and without reduction for or on account of, any Taxes. If any Taxes are
required to be withheld or deducted from any amounts payable to the Borrower
under this Agreement, the Liquidity Provider shall (i) within the time
prescribed therefor by applicable law pay to the appropriate governmental or
taxing authority the full amount of any such Taxes (and any additional Taxes in
respect of the payment required under clause (ii) hereof) and make such reports
or returns in connection therewith at the time or times and in the manner
prescribed by applicable law, and (ii) pay to the Borrower an additional

                                       14
<Page>

amount which (after deduction of all such Taxes) will be sufficient to yield to
the Borrower the full amount which would have been received by it had no such
withholding or deduction been made. Within 30 days after the date of each
payment hereunder, the Liquidity Provider shall furnish to the Borrower the
original or a certified copy of (or other documentary evidence of) the payment
of the Taxes applicable to such payment.

                  (c) If any exemption from, or reduction in the rate of, any
Taxes is reasonably available to the Borrower to establish that payments under
this Agreement are exempt from (or entitled to a reduced rate of) tax, the
Borrower shall deliver to the Liquidity Provider such form or forms and such
other evidence of the eligibility of the Borrower for such exemption or
reduction as the Liquidity Provider may reasonably identify to the Borrower as
being required as a condition to exemption from, or reduction in the rate of,
any Taxes.

                  Section 3.04. PAYMENTS. The Borrower shall make or cause to be
made each payment to the Liquidity Provider under this Agreement so as to cause
the same to be received by the Liquidity Provider not later than 1:00 P.M. (New
York City time) on the day when due. The Borrower shall make all such payments
in lawful money of the United States of America, to the Liquidity Provider in
immediately available funds, by wire transfer to Citibank N.A., New York, ABA #
021000089, Account No. 10920118, Reference: Northwest Airlines EETC 2001-1B
#4187944, Attention: M. Kirr MT215000.

                  Section 3.05. COMPUTATIONS. All computations of interest based
on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the LIBOR Rate shall be
made on the basis of a year of 360 days, in each case for the actual number of
days (including the first day but excluding the last day) occurring in the
period for which such interest is payable.

                  Section 3.06. PAYMENT ON NON-BUSINESS DAYS. Whenever any
payment to be made hereunder shall be stated to be due on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day and
no additional interest shall be due as a result (and if so made, shall be deemed
to have been made when due). If any payment in respect of interest on an Advance
is so deferred to the next succeeding Business Day, such deferral shall not
delay the commencement of the next Interest Period for such Advance (if such
Advance is a LIBOR Advance) or reduce the number of days for which interest will
be payable on such Advance on the next interest payment date for such Advance.

                  Section 3.07. INTEREST. (a) Subject to Section 2.09, the
Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of
such Advance (or, in the case of an Applied Provider Advance, from and including
the date on which the amount thereof was withdrawn from the Class B Cash
Collateral Account to pay interest on the Class B Certificates) to but excluding
the date such principal amount shall be paid in full (or, in the case of an
Applied Provider Advance, the date on which the Class B Cash Collateral Account
is fully replenished in respect of such Advance) and (ii) any other amount due
hereunder (whether fees, commissions, expenses or other amounts or, to the
extent permitted by law, installments of interest on Advances or any such other
amount) which is not paid when due (whether at stated maturity, by acceleration
or otherwise) from and including the due date thereof to but excluding the date
such amount is paid

                                       15

in full, in each such case, at a fluctuating interest rate per annum for each
day equal to the Applicable Liquidity Rate (as defined below) for such Advance
or such other amount as in effect for such day, but in no event at a rate per
annum greater than the maximum rate permitted by applicable law; PROVIDED,
HOWEVER, that, if at any time the otherwise applicable interest rate as set
forth in this Section 3.07 shall exceed the maximum rate permitted by applicable
law, then any subsequent reduction in such interest rate will not reduce the
rate of interest payable pursuant to this Section 3.07 below the maximum rate
permitted by applicable law until the total amount of interest accrued equals
the amount of interest that would have accrued if such otherwise applicable
interest rate as set forth in this Section 3.07 had at all times been in effect.

                  (b) Each Advance (other than any Unapplied Non-Extension
Advance) will be either a Base Rate Advance or a LIBOR Advance as provided in
this Section. Each such Advance will be a Base Rate Advance for the period from
the date of its borrowing to (but excluding) the third Business Day following
the Liquidity Provider's receipt of the Notice of Borrowing for such Advance.
Thereafter, such Advance shall be a LIBOR Advance; PROVIDED that (i) an Applied
Provider Advance (other than an Unapplied Non-Extension Advance) shall always be
a LIBOR Advance unless the Borrower elects otherwise and (ii) the Borrower (at
the direction of the Controlling Party, so long as the Liquidity Provider is not
the Controlling Party) may (x) convert the Final Advance into a Base Rate
Advance on the last day of an Interest Period for such Advance by giving the
Liquidity Provider no less than four Business Days' prior written notice of such
election or (y) elect to maintain the Final Advance as a Base Rate Advance by
not requesting a conversion of the Final Advance to a LIBOR Advance under Clause
(5) of the applicable Notice of Borrowing (or, if such Final Advance is deemed
to have been made, without delivery of a Notice of Borrowing pursuant to Section
2.06, by requesting, prior to 11:00 A.M. (New York City time) on the first
Business Day immediately following the Borrower's receipt of the applicable
Termination Notice, that such Final Advance not be converted from a Base Rate
Advance to a LIBOR Advance).

                  (c) Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest
Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on
the last day of such Interest Period and, in the event of the payment of
principal of such LIBOR Advance on a day other than such last day, on the date
of such payment (to the extent of interest accrued on the amount of principal
repaid).

                  (d) Each Base Rate Advance shall bear interest at a rate per
annum equal to the Base Rate plus the Applicable Margin for such Base Rate
Advance, payable in arrears on each Regular Distribution Date and, in the event
of the payment of principal of such Base Rate Advance on a day other than a
Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid).

                  (e) Each Unapplied Non-Extension Advance shall bear interest
in an amount equal to the Investment Earnings on amounts on deposit in the Class
B Cash Collateral Account plus the Applicable Margin for such Unapplied
Non-Extension Advance on the amount of such Unapplied Non-Extension Advance from
time to time, payable in arrears on each Distribution Date.

<Page>

                  (f) Each amount not paid when due hereunder (whether fees,
commissions, expenses or other amounts or, to the extent permitted by applicable
law, installments of interest on Advances but excluding Advances) shall bear
interest at a rate per annum equal to the Base Rate plus 2.0% until paid.

                  (g) Each change in the Base Rate shall become effective
immediately. The rates of interest specified in this Section 3.07 with respect
to any Advance or other amount shall be referred to as the "APPLICABLE LIQUIDITY
RATE".

                  Section 3.08. REPLACEMENT OF BORROWER. From time to time and
subject to the successor Borrower's meeting the eligibility requirements set
forth in Section 6.9 of the Intercreditor Agreement applicable to the
Subordination Agent, upon the effective date and time specified in a written and
completed Notice of Replacement Subordination Agent in substantially the form of
Annex VI attached hereto (a "NOTICE OF REPLACEMENT SUBORDINATION AGENT")
delivered to the Liquidity Provider by the then Borrower, the successor Borrower
designated therein shall be substituted for as the Borrower for all purposes
hereunder.

                  Section 3.09. FUNDING LOSS INDEMNIFICATION. The Borrower shall
pay to the Liquidity Provider, upon the request of the Liquidity Provider, such
amount or amounts as shall be sufficient (in the reasonable opinion of the
Liquidity Provider) to compensate it for any loss, cost, or expense incurred as
a result of:

                        (1) Any repayment of a LIBOR Advance on a date other
                  than the last day of the Interest Period for such Advance; or

                        (2) Any failure by the Borrower to borrow a LIBOR
                  Advance on the date for borrowing specified in the relevant
                  notice under Section 2.02.

                  Section 3.10. ILLEGALITY. Notwithstanding any other provision
in this Agreement, if any change in any applicable law, rule or regulation, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Liquidity Provider (or its Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful
or impossible for the Liquidity Provider (or its Lending Office) to maintain or
fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity
Provider, the outstanding principal amount of the LIBOR Advances shall be
converted to Base Rate Advances (a) immediately upon demand of the Liquidity
Provider, if such change or compliance with such request, in the judgment of the
Liquidity Provider, requires immediate repayment; or (b) at the expiration of
the last Interest Period to expire before the effective date of any such change
or request.

Agreement, including, but not limited to, the Liquidity Provider's failure to
make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly complying with the terms and conditions hereof.

                  (b) Neither the Liquidity Provider nor any of its officers,
employees, directors or affiliates shall be liable or responsible in any respect
for (i) any error, omission, interruption or delay in transmission, dispatch or
delivery of any message or advice, however transmitted, in connection with this
Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action,
inaction or omission which may be taken by it in good faith, absent willful
misconduct or negligence (in which event the extent of the Liquidity Provider's
potential liability to the Borrower shall be limited as set forth in the
immediately preceding paragraph), in connection with this Agreement or any
Notice of Borrowing.

                  Section 7.07. COSTS, EXPENSES AND TAXES. The Borrower agrees
to pay, or cause to be paid (A) on the Effective Date and on such later date or
dates on which the Liquidity Provider shall make demand, all reasonable
out-of-pocket costs and expenses (including, without limitation, the reasonable
fees and expenses of outside counsel for the Liquidity Provider) of the
Liquidity Provider in connection with the preparation, negotiation, execution,
delivery, filing and recording of this Agreement, any other Operative Agreement
and any other documents which may be delivered in connection with this Agreement
and (B) on demand, all reasonable costs and expenses (including reasonable
counsel fees and expenses) of the Liquidity Provider in connection with (i) the
enforcement of this Agreement or any other Operative Agreement, (ii) the
modification or amendment of, or supplement to, this Agreement or any other
Operative Agreement or such other documents which may be delivered in connection
herewith or therewith (whether or not the same shall become effective) or (iii)
any action or proceeding relating to any order, injunction, or other process or
decree restraining or seeking to restrain the Liquidity Provider from paying any
amount under this Agreement, the Intercreditor Agreement or any other Operative
Agreement or otherwise affecting the application of funds in the Class B Cash
Collateral Account. In addition, the Borrower shall pay any and all recording,
stamp and other similar taxes and fees payable or determined to be payable in
connection with the execution, delivery, filing and recording of this Agreement,
any other Operative Agreement and such other documents, and agrees to save the
Liquidity Provider harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such taxes
or fees.

                  Section 7.08. BINDING EFFECT; PARTICIPATIONS. (a) This
Agreement shall be binding upon and inure to the benefit of the Borrower and the
Liquidity Provider and their respective successors and assigns, except that
neither the Liquidity Provider (except as otherwise provided in this Section
7.08) nor (except as contemplated by Section 3.08) the Borrower shall have the
right to assign its rights or obligations hereunder or any interest herein
without the prior written consent of the other party, subject to the
requirements of Section 7.08(b). The Liquidity Provider may grant participations
herein or in any of its rights hereunder (including, without limitation, funded
participations and participations in rights to receive interest payments
hereunder) and under the other Operative Agreements to such Persons as the
Liquidity Provider may in its sole discretion select (but excluding Northwest
and any of its Affiliates), subject to the requirements of Section 7.08(b). No
such granting of participations by the Liquidity Provider, however, will relieve
the Liquidity Provider of its obligations hereunder. In connection with any
participation or any proposed participation, the Liquidity Provider may disclose
to the participant or the proposed participant any information that the Borrower
is required to deliver or to disclose to the Liquidity Provider pursuant to this
Agreement. The Borrower acknowledges and agrees that the Liquidity Provider's
source of funds may derive in part from its participants.

                                       23
<Page>

Accordingly, references in this Agreement and the other Operative Agreements to
determinations, reserve and capital adequacy requirements, increased costs,
reduced receipts, additional amounts due pursuant to Section 3.03 and the like
as they pertain to the Liquidity Provider shall be deemed also to include those
of each of its participants (subject, in each case, to the maximum amount that
would have been incurred by or attributable to the Liquidity Provider directly
if the Liquidity Provider, rather than the participant, had held the interest
participated).

                  (b) If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity
(each, a "TRANSFEREE"), then, concurrently with the effectiveness of such
participation, the Transferee shall (i) represent to the Liquidity Provider (for
the benefit of the Liquidity Provider and the Borrower) either (A) that it is
incorporated under the laws of the United States or a state thereof or (B) that
under applicable law and treaties, no taxes will be required to be withheld with
respect to any payments to be made to such Transferee in respect of this
Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a
statement that it is incorporated under the laws of the United States or a state
thereof or (y) if it is not so incorporated, two copies of a properly completed
United States Internal Revenue Service Form W-8BEN or Form W-8ECI, as
appropriate, or other applicable form, certificate or document prescribed by the
Internal Revenue Service certifying, in each case, such Transferee's entitlement
to a complete exemption from United States federal withholding tax in respect to
any and all payments to be made hereunder, and (iii) agree (for the benefit of
the Liquidity Provider and the Borrower) to provide the Liquidity Provider and
the Borrower a new Form W-8BEN or Form W-8ECI, as appropriate, (A) on or before
the date that any such form expires or becomes obsolete or (B) after the
occurrence of any event requiring a change in the most recent form previously
delivered by it and prior to the immediately following due date of any payment
by the Borrower hereunder, certifying in the case of a Form W-8ECI or Form
W-8BEN that such Transferee is entitled to a complete exemption from United
States federal withholding tax on payments under this Agreement. Unless the
Borrower has received forms or other documents reasonably satisfactory to it
(and required by applicable law) indicating that payments hereunder are not
subject to United States federal withholding tax, the Borrower will withhold
taxes as required by law from such payments at the applicable statutory rate.

                  (c) Notwithstanding the other provisions of this Section 7.08,
the Liquidity Provider may assign and pledge all or any portion of the Advances
owing to it to any Federal Reserve Bank or the United States Treasury as
collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank, provided that any payment in respect of such assigned Advances made by the
Borrower to the Liquidity Provider in accordance with the terms of this
Agreement shall satisfy the Borrower's obligations hereunder in respect of such
assigned Advance to the extent of such payment. No such assignment shall release
the Liquidity Provider from its obligations hereunder.

                  Section 7.09. SEVERABILITY. Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or non-authorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

            Provider shall have been notified pursuant thereto; and

                  (iv) agrees that nothing herein shall affect the right to
            effect service of process in any other manner permitted by law or
            shall limit the right to sue in any other jurisdiction.

                  (b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE

voluntarily waives its jury trial rights following consultation with such legal
counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN
