                  Date, the original aggregate face amount of the Certificates
                  of such Trust) and (y) the Pool Balance of such Certificates
                  as of the Current Distribution Date calculated on the basis

                  paid in full and such payments have been distributed to the
                  holders of such Certificates but without giving effect to any

                  preceding Distribution Date (or, if the Current Distribution
                  Date is the first Distribution Date, occurring after the
                  initial issuance of the Certificates of such Trust) and

                        (B) the amount of the excess, if any, by which (i) the

                  aggregate amount of the Deposits for such Class of
                  Certificates) other than any portion of such Deposits
                  thereafter used to acquire Equipment Notes pursuant to the
                  Note Purchase Agreement, over (ii) the Aggregate LTV
                  Collateral Amount for such Class of Certificates for the
                  Current Distribution Date;

                  PROVIDED that, (x) until the date of the initial LTV
            Appraisals for all of the Aircraft, clause (B) above shall not be
            applicable and (y) in the case of the Class D Certificates, clause
            (B) above shall not be applicable.

            not been distributed to the Certificateholders of such Trust (other
            than such premium or a portion thereof applied to the payment of
            interest on the Certificates of such Trust or the reduction of the
            Pool Balance of such Trust) shall be added to the amount of such
            Adjusted Expected Distributions.

                  "AFFILIATE" means, with respect to any Person, any other
            Person directly or indirectly controlling, controlled by or under
            common control with such Person. For the purposes of this

            direct or cause the direction of the management and policies of such
            Person whether through the ownership of voting securities or by
            contract or otherwise; and the terms "controlling" and "controlled"
            have meanings correlative to the foregoing.

Liquidity Facility to which it is a party, has agreed to look solely to such
amounts to the extent available for distribution to it as provided in this
Agreement and to the relevant Deposits and that none of the Trustees, Owner
Trustees, Loan Trustees, Owner Participants nor the Subordination Agent is
personally liable to any of them for any amounts payable or any liability under
this Agreement, any Trust Agreement, any Liquidity Facility or such Certificate,
except (in the case of the Subordination Agent) as expressly provided herein or
(in the case of the Trustees) as expressly provided in each Trust Agreement or
(in the case of the Owner Trustees and the Loan Trustees) as expressly provided
in any Operative Agreement.

                  Section 2.2. TRUST ACCOUNTS. (a) Upon the execution of this
Agreement, the Subordination Agent shall establish and maintain in its name (i)
the Collection Account as an Eligible Deposit Account, bearing a designation
clearly indicating that the funds deposited therein are held in trust for the
benefit of the Trustees, the Certificateholders and the Liquidity Providers and
(ii) as a sub-account in the Collection Account, the Special Payments Account as
an Eligible Deposit Account, bearing a designation clearly indicating that the
funds deposited therein are held in trust for the benefit of the Trustees, the
Certificateholders and the Liquidity Providers. The Subordination Agent shall
establish and maintain the Cash Collateral Accounts pursuant to and under the
circumstances set forth in Section 3.6(f) hereof. Upon such establishment and
maintenance under Section 3.6(f) hereof, the Cash Collateral Accounts shall,
together with the Collection Account, constitute the "TRUST ACCOUNTS" hereunder.

                  (b) Funds on deposit in the Trust Accounts shall be invested
and reinvested by the Subordination Agent in Eligible Investments selected by
the Subordination Agent if such


                                      -23-

investments are reasonably available and have maturities no later than the
earlier of (i) 90 days following the date of such investment and (ii) the
Business Day immediately preceding the Regular Distribution Date or the date of
the related distribution pursuant to Section 2.4 hereof, as the case may be,
next following the date of such investment; PROVIDED, HOWEVER, that following
the making of a Non-Extension Drawing, the Subordination Agent shall invest and
reinvest such amounts in Eligible Investments at the direction of the Liquidity
Provider; PROVIDED FURTHER, however, that upon the occurrence and during the
continuation of a Triggering Event, the Subordination Agents shall invest and
reinvest such amounts (other than amounts in the Cash Collateral Accounts as a
result of a Non-Extension Drawing, which shall be governed by the foregoing
proviso) in Eligible Investments in accordance with the written instructions of
the Controlling Party. Unless otherwise expressly provided in this Agreement
(including, without limitation, with respect to Investment Earnings on deposit
in the Cash Collateral Accounts, Section 3.6(f) hereof), any Investment Earnings
shall be deposited in the Collection Account when received by the Subordination
Agent and shall be applied by the Subordination Agent in the same manner as the
principal amount of such investment is to be applied and any losses shall be
charged against the principal amount invested, in each case net of the
Subordination Agent's reasonable fees and expenses in making such investments.
The Subordination Agent shall not be liable for any loss resulting from any
investment, reinvestment or liquidation required to be made under this Agreement
other than by reason of its willful misconduct or gross negligence or, with
respect to the handling or transfer of funds, ordinary negligence. Eligible
Investments and any other investment required to be made hereunder shall be held
to their maturities except that any such investment may be sold (without regard
to its maturity) by the Subordination Agent without instructions whenever such
sale is necessary to make a distribution required under this Agreement.
Uninvested funds held hereunder shall not earn or accrue interest.

                  (c) The Subordination Agent shall possess all right, title and
interest in all funds on deposit from time to time in the Trust Accounts and in
all proceeds thereof (including all income thereon, except as otherwise provided
herein with respect to Investment Earnings). The Trust Accounts shall be held in
trust by the Subordination Agent under the sole dominion and control of the
Subordination Agent for the benefit of the Trustees, the Certificateholders and
the Liquidity Providers, as the case may be. If, at any time, any of the Trust
Accounts ceases to be an Eligible Deposit Account, the Subordination Agent shall
within 10 Business Days (or such longer period, not to exceed 30 calendar days,
to which each Rating Agency may consent) establish a new Collection Account,
Special Payments Account or Cash Collateral Account, as the case may be, as an
Eligible Deposit Account and shall transfer any cash and/or any investments to
such new Collection Account, Special Payments Account or Cash Collateral
Account, as the case may be. So long as the Subordination Agent is an Eligible
Institution, the Trust Accounts shall be maintained with it as Eligible Deposit
Accounts.

                  Section 2.3. DEPOSITS TO THE COLLECTION ACCOUNT AND SPECIAL
PAYMENTS ACCOUNT. (a) The Subordination Agent shall, upon receipt thereof,
deposit in the Collection Account all Scheduled Payments received by it.

                  (b) The Subordination Agent shall, on each date when one or
more Special Payments are made to the Subordination Agent as holder of the
Equipment Notes, deposit in the Special Payments Account the aggregate amount of
such Special Payments.

                  Section 2.4. DISTRIBUTIONS OF SPECIAL PAYMENTS. (a) NOTICE OF
SPECIAL PAYMENT. Except as provided in Section 2.4(e), upon receipt by the
Subordination Agent, as registered holder of the Equipment Notes, of any notice
of a Special Payment (or, in the absence of any such notice, upon receipt by the
Subordination Agent of a Special Payment), the Subordination Agent shall
promptly give notice thereof to each Trustee and the Liquidity Providers. The
Subordination Agent shall promptly calculate the amount of the redemption or
purchase of Equipment Notes or the amount of any Overdue Scheduled Payment, as
the case may be, comprising such Special Payment under the applicable Indenture
or Indentures and shall promptly send to each Trustee and the Liquidity Provider
a Written Notice of such amount and the amount allocable to each Trust. Such
Written Notice shall also set the distribution date for such Special Payment (a
"SPECIAL DISTRIBUTION DATE"), which shall be a Business Day which follows the
later to occur of (x) the 15th day after the date of such Written Notice or (y)
the date the Subordination Agent has received or expects to receive such Special
Payment. Amounts on deposit in the Special Payments Account shall be distributed
in accordance with Sections 2.4(b) and 2.4(c) hereof, as applicable.

                  (b) (i) REDEMPTIONS AND PURCHASES OF EQUIPMENT NOTES. So long
as no Triggering Event shall have occurred (whether or not continuing), the
Subordination Agent shall make distributions pursuant to this Section 2.4(b) of
amounts on deposit in the Special Payments Account on account of the redemption
or purchase (including, without limitation, a purchase resulting from the sale
of the Equipment Notes permitted by Article IV hereof) of all of the Equipment
Notes issued pursuant to an Indenture on the Special Distribution Date for such
Special Payment in the following order of priority:

                  FIRST, such amount as shall be required to pay (A) all accrued
            and unpaid Liquidity Expenses then in arrears PLUS (B) the product
            of (x) the aggregate amount of all accrued and unpaid Liquidity
            Expenses not in arrears to such Special Distribution Date MULTIPLIED
            BY (y) a fraction, the numerator of which is the aggregate
            outstanding principal amount of Equipment Notes (other than Series D
            Equipment Notes) being redeemed, purchased or prepaid on such
            Special Distribution Date and the denominator of which is the
            aggregate outstanding principal amount of all Equipment Notes (other
            than Series D Equipment Notes) (the "SECTION 2.4(b) FRACTION")
            ("ACCRUED AMOUNTS"), shall be distributed to the applicable
            Liquidity Providers PRO RATA on the basis of the amount of Liquidity
            Expenses owed to each Liquidity Provider;

                  SECOND, such amount as shall be required to pay (A) all
            accrued and unpaid interest then in arrears on all Liquidity
            Obligations PLUS (B) the product of (x) the aggregate amount of all
            accrued and unpaid interest on all Liquidity Obligations not in
            arrears to such Special Distribution Date (at the rate provided in
            the applicable Liquidity Facility) MULTIPLIED BY (y) the Section
            2.4(b) Fraction, shall be distributed to the Liquidity Providers PRO
            RATA on the basis of the amount of such accrued and unpaid interest
            owed to each Liquidity Provider;

                  THIRD, such amount as shall be required (A) if any Cash
            Collateral Account had been previously funded as provided in Section
            3.6(f), to fund such Cash Collateral Account up to its Required
            Amount shall be deposited in such Account, (B) if any Liquidity
            Facility shall become a Downgraded Facility or a Non-Extended
            Facility at a


                                      -25-
<Page>

            time when unreimbursed Interest Drawings under such Liquidity
            Facility have reduced the Available Amount thereunder to zero, to
            deposit into the related Cash Collateral Account an amount equal to
            such Account's Required Amount shall be deposited in such Account,
            and (C) if with respect to any particular Liquidity Facility neither
            subclause (A) nor subclause (B) of this clause "third" is
            applicable, to pay or reimburse the Liquidity Provider in respect of
            such Liquidity Facility in an amount equal to the amount of any
            unreimbursed Interest Drawings under such Liquidity Facility shall
            be distributed to such Liquidity Provider, PRO RATA on the basis of
            the amounts of all such deficiencies and/or unreimbursed Interest
            Drawings;

                  FOURTH, if, with respect to any particular Liquidity Facility,
            any amounts are to be distributed pursuant to either subclause (A)
            or (B) of clause "THIRD" above, then the Liquidity Provider with
            respect to such Liquidity Facility shall be paid the excess of (x)
            the aggregate outstanding amount of unreimbursed Advances (whether
            or not then due) under such Liquidity Facility over (y) the Required
            Amount for the relevant Class, PRO RATA on the basis of such amounts
            in respect of each Liquidity Provider;

                  FIFTH, such amount as shall be required to pay in full
            Expected Distributions to the holders of Class A-1 and Class A-2
            Certificates on such Special Distribution Date shall be distributed
            to the Class A-1 and Class A-2 Trustees; PROVIDED that if available
            funds are insufficient to pay an Expected Distribution to each such
            Class in full, available funds will be distributed to each of the
            Class A-1 Trustee and Class A-2 Trustee in the same proportion as
            such Trustee's proportionate share of the aggregate amount of such
            Expected Distributions;

                  SIXTH, such amount as shall be required to pay in full
            Expected Distributions to the holders of Class B Certificates on
            such Special Distribution Date shall be distributed to the Class B
            Trustee;

                  SEVENTH, such amount as shall be required to pay in full
            Expected Distributions to the holders of Class C Certificates on
            such Special Distribution Date shall be distributed to the Class C
            Trustee;

                  EIGHTH, such amount as shall be required to pay in full
            Expected Distributions to the holders of Class D Certificates, if
            any, on such Special Distribution Date shall be distributed to the
            Class D Trustee; and

                  NINTH, the balance, if any, of such Special Payment shall be
            transferred to the Collection Account for distribution in accordance
            with Section 3.2 hereof.

For the purpose of this Section 2.4(b)(i), clause (x) of the definition of
"Expected Distributions" shall be deemed to read as follows: "(x) accrued, due
and unpaid interest on such Certificates excluding interest, if any, payable
with respect to the Deposits related to such Trust".

                  (ii) Upon the occurrence of a Triggering Event (whether or not
            continuing), the Subordination Agent shall make distributions
            pursuant to this Section 2.4(b) of amounts on deposit in the Special
            Payments Account on account of the redemption or


                                      -26-
<Page>

            purchase of all of the Equipment Notes issued pursuant to an
            Indenture on the Special Distribution Date for such Special Payment
            in accordance with Section 3.3 hereof.

                  (c) OTHER SPECIAL PAYMENTS. Except as provided in clause (e)
below, any amounts on deposit in the Special Payments Account other than in
respect of amounts to be distributed pursuant to Section 2.4(b) shall be
distributed on the Special Distribution Date therefor in accordance with Article
III hereof.

                  (d) INVESTMENT OF AMOUNTS IN SPECIAL PAYMENTS ACCOUNT. Any
amounts on deposit in the Special Payments Account prior to the distribution
thereof pursuant to Section 2.4(b) or (c) shall be invested in accordance with
Section 2.2(b). Investment Earnings on such investments shall be distributed in
accordance with Section 2.4(b) or (c), as the case may be.

                  (e) CERTAIN PAYMENTS. The Subordination Agent will distribute
promptly upon receipt thereof (i) any indemnity payment received by it from the
Owner Participant, the Owner Trustee or Northwest in respect of any Trustee, any
Liquidity Provider, Paying Agent, Depositary or any Escrow Agent (collectively,
the "PAYEES") and (ii) any compensation (including, without limitation, any fees
payable to any Liquidity Provider under the Fee Letters) received by it from the
Owner Participant, the Owner Trustee or Northwest under any Operative Agreement
in respect of any Payee, directly to the Payee entitled thereto.

                  Section 2.5. DESIGNATED REPRESENTATIVES. (a) With the delivery
of this Agreement, the Subordination Agent shall furnish to each Liquidity
Provider and each Trustee, and from time to time thereafter may furnish to each

made more than one time in any 12-month period), a certificate (a "SUBORDINATION
AGENT INCUMBENCY CERTIFICATE") of a Responsible Officer of the Subordination
Agent certifying as to the incumbency and specimen signatures of the officers of
the Subordination Agent and the attorney-in-fact and agents of the Subordination
Agent (the "SUBORDINATION AGENT REPRESENTATIVES") authorized to give Written
Notices on behalf of the Subordination Agent hereunder. Until each Liquidity
Provider and Trustee receives a subsequent Subordination Agent Incumbency
Certificate, it shall be entitled to rely on the last Subordination Agent
Incumbency Certificate delivered to it hereunder.

                  (b) With the delivery of this Agreement, each Trustee shall
furnish to the Subordination Agent, and from time to time thereafter may furnish
to the Subordination Agent, at such Trustee's discretion, or upon the
Subordination Agent's request (which request shall not be made more than one
time in any 12-month period), a certificate (a "TRUSTEE INCUMBENCY CERTIFICATE")
of a Responsible Officer of such Trustee certifying as to the incumbency and
specimen signatures of the officers of such Trustee and the attorney-in-fact and
agents of such Trustee (the "TRUSTEE REPRESENTATIVES") authorized to give

to rely on the last Trustee Incumbency Certificate delivered to it hereunder.

                  (c) With the delivery of this Agreement, each Liquidity
Provider shall furnish to the Subordination


                                      -27-
<Page>

Agent, and from time to time thereafter may furnish to the Subordination Agent,
at such Liquidity Provider's discretion, or upon the Subordination Agent's
request (which request shall not be made more than one time in any 12-month
period), a certificate (an "LP INCUMBENCY CERTIFICATE") of any authorized
signatory of such Liquidity Provider certifying as to the incumbency and
specimen signatures of any officer, attorney-in-fact, agent or other designated

authorized to give Written Notices on behalf of such Liquidity Provider
hereunder. Until the Subordination Agent receives a subsequent LP Incumbency
Certificate, it shall be entitled to rely on the last LP Incumbency Certificate
delivered to it hereunder.

                  Section 2.6. CONTROLLING PARTY. (a) The Trustees and the
Liquidity Providers hereby agree that, with respect to any Indenture at any
given time, the Loan Trustee thereunder will be directed (i) in taking, or
refraining from taking, any action with respect to such Indenture or the
Equipment Notes issued thereunder, so long as no Indenture Default has occurred
and is continuing thereunder, by the holders of at least a majority of the
outstanding principal amount of such Equipment Notes (PROVIDED that, for so long
as the Subordination Agent is the registered holder of the Equipment Notes, the
Subordination Agent shall act with respect to this clause (i) in accordance with
the directions of the Trustees of Trusts for which the related Trust Properties
include, in the aggregate, such a majority of outstanding principal amount of
Equipment Notes), and (ii) after the occurrence and during the continuance of an
Indenture Default thereunder (which, in the case of an Indenture pertaining to a
Leased Aircraft, has not been cured by the applicable Owner Trustee or the
applicable Owner Participant, if applicable, pursuant to Section 4.03 of such
Indenture), in taking, or refraining from taking, any action with respect to
such Indenture or such Equipment Notes, including exercising remedies thereunder
(including accelerating the Equipment Notes issued thereunder or foreclosing the
Lien on the Aircraft securing such Equipment Notes), by the Controlling Party.

                  (b) Subject to subparagraph (c) below, the Person who shall be
the "CONTROLLING PARTY" with respect to any Indenture shall be: (w) the Class
A-1 or Class A-2 Trustee, whichever represents the Class with the larger
principal amount of Certificates outstanding at the time that the Indenture
Default occurs, until payment of final distributions to the holders of such
larger Class, and thereafter the other of the Class A-1 Trustee or Class A-2
Trustee, until payment of final distributions to the holders of such other
Class; (x) upon payment of Final Distributions to the holders of Class A-1 and
Class A-2 Certificates, the Class B Trustee; (y) upon payment of Final
Distributions to the holders of Class B Certificates, the Class C Trustee; and
(z) upon payment of Final Distributions to the holders of Class C Certificates,
the Class D Trustee, if there be one. For purposes of giving effect to the
foregoing, the Trustees (other than the Controlling Party) irrevocably agree
(and the Certificateholders (other than the Certificateholders represented by
the Controlling Party) shall be deemed to agree by virtue of their purchase of
Certificates) that the Subordination Agent, as record holder of the Equipment
Notes, shall exercise its voting rights in respect of the Equipment Notes as
directed by the Controlling Party and any vote so exercised shall be binding
upon the Trustees and all Certificateholders.

                  The Subordination Agent shall give Written Notice to all of
the other parties to this Agreement promptly upon a change in the identity of
the Controlling Party. Each of the parties hereto agrees that it shall not
exercise any of the rights of the Controlling Party at such time as it is not
the Controlling Party hereunder; PROVIDED, however, that nothing herein


                                      -28-
<Page>

contained shall prevent or prohibit any Non-Controlling Party from exercising
such rights as shall be specifically granted to such Non-Controlling Party
hereunder and under the other Operative Agreements.

                  (c) Notwithstanding the foregoing, at any time after 18 months
from the earliest to occur of (i) the date on which the entire Available Amount
under any Liquidity Facility shall have been drawn (for any reason other than a
Downgrade Drawing or a Non-Extension Drawing) and any amount remains
unreimbursed, (ii) the date on which the entire amount of any Downgrade Drawing
or Non-Extension Drawing has been withdrawn from a Cash Collateral Account to
pay interest on the related Class of Certificates and remains unreimbursed and
(iii) the date on which all Equipment Notes shall have been Accelerated
(provided that with respect to the period prior to the Delivery Period Expiry
Date, such Equipment Notes have an aggregate outstanding principal balance in
excess of $300,000,000), the Liquidity Provider with the highest outstanding
amount of unreimbursed Liquidity Obligations (so long as such Liquidity Provider
has not defaulted in its obligation to make any advance under any Liquidity
Facility) shall have the right to elect, by Written Notice to the Subordination
Agent and each of the Trustees, to become the Controlling Party hereunder with
respect to any Indenture at any time from and including the last day of such
18-month period.

                  (d) The exercise of remedies by the Controlling Party under
this Agreement shall be expressly limited by Section 4.1(a)(ii) hereof.

                  (e) The Controlling Party shall not be entitled to require or
obligate any Non-Controlling Party to provide funds necessary to exercise any
right or remedy hereunder.

Certificateholders for which it is acting) pursuant to Section 2.4, 3.2 or 3.3

Person shall, by a Written Notice, so inform the Subordination Agent and each
other party to this Agreement.

                  (d) As provided in Section 6.5 hereof, the Subordination Agent

funds so withheld.

                  (g) On such dates (but not more frequently than monthly) as
any Liquidity Provider or any Trustee shall request, the Subordination Agent

                  Section 3.6. LIQUIDITY FACILITIES. (a) INTEREST DRAWINGS. If

payment of any amounts due and owing in respect of accrued interest on the Class
A-1 Certificates, the Class A-2 Certificates, the Class B Certificates or the

drawing, an "INTEREST DRAWING") under the Liquidity Facility with respect to
such Class of Certificates in an amount equal to the lesser of (i) an amount
sufficient to pay the amount of such accrued interest (at the Stated Interest
Rate for such Class of Certificates) or (ii) the Available Amount under such
Liquidity Facility, and shall pay such amount to the Trustee with respect to
such Class of Certificates in payment of such accrued interest.

                  (b) APPLICATION OF INTEREST DRAWINGS. Notwithstanding anything
to the contrary contained in this Agreement, (i) all payments received by the
Subordination Agent in respect of an Interest Drawing under the Class A-1

Class A-1 Cash Collateral Account, and payable in each case to the Class A-1
Certificateholders, shall be promptly distributed to the Class A-1 Trustee and
(ii) all payments received by the Subordination Agent in respect of an Interest

                  (c) DOWNGRADE DRAWINGS. If at any time a Downgrade Event
occurs with respect to any Liquidity Provider, within ten (10) days (or
forty-five (45) days in the event that such Liquidity Provider's short-term
unsecured debt rating by Standard & Poor's is downgraded from A-1+ to A-1 and
the applicable Threshold Rating is A-1+ for Standard & Poor's) after receiving
notice of such Downgrade Event (but no later than the expiration date of the
Liquidity Facility issued by the Liquidity Provider (the "DOWNGRADED FACILITY")
in respect of which the Downgrade Event occurs), such Liquidity Provider may
arrange, or the Subordination Agent (in consultation with Northwest), may
arrange for a Replacement Liquidity Provider to issue and deliver a Replacement
Liquidity Facility to the Subordination Agent. If a Downgraded Facility has not
been replaced in accordance with the terms of this paragraph, the Subordination
Agent shall, on such 10th day or 45th day, as the case may be (or if such 10th
day or 45th day is not a Business Day, on the next succeeding Business Day) (or,
if earlier, the expiration date of such Downgraded Facility), request a drawing
in accordance with and to the extent permitted by such Downgraded Facility (such
drawing, a "DOWNGRADE DRAWING") of all available and undrawn amounts thereunder.
Amounts drawn pursuant to a Downgrade Drawing shall be maintained and invested
as provided in Section 3.6(f) hereof. The Liquidity Provider may also arrange
for a Replacement Liquidity Provider to issue and deliver a Replacement
Liquidity Facility at any


                                      -36-
<Page>

time after such Downgrade Drawing so long as such Downgrade Drawing has not been
reimbursed in full to the Liquidity Provider.

                  (d) NON-EXTENSION DRAWINGS. If any Liquidity Facility with
respect to any Class of Certificates is scheduled to expire on a date (the
"STATED EXPIRATION DATE") prior to the date that is 15 days after the Final
Legal Distribution Date for such Class of Certificates, then, no earlier than
the 60th day and no later than the 40th day prior to the then Stated Expiration
Date, the Subordination Agent shall request that such Liquidity Provider extend
the Stated Expiration Date to the earlier of (i) the date which is 15 days after
the Final Legal Distribution Date for such Class of 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) (unless the obligations
of such Liquidity Provider thereunder are earlier terminated in accordance with
such Liquidity Facility); PROVIDED HOWEVER, that at its option a Liquidity
Provider may elect to extend the Stated Expiration Date for its Liquidity
Facility for any Class of Certificates to the date that is 15 days after the
Final Legal Distribution Date for the relevant Class of Certificates in
accordance with Section 2.11 of such Liquidity Facility. Whether or not the
Liquidity Provider has received a request from the Subordination Agent, the
Liquidity Provider may, but shall not be obligated to, advise the Subordination
Agent, no earlier than the 40th day (or, if earlier, the date of such Liquidity
Provider's receipt of such request, if any, from the Subordination Agent) and no
later than the 25th day prior to the Stated Expiration Date then in effect for
the Liquidity Facility of such Liquidity Provider (such period, with respect to
such Liquidity Facility, the "CONSENT PERIOD"), whether, in its sole and
absolute discretion, it agrees to so extend the Stated Expiration Date. If, on
or before the date on which such Consent Period ends, such Liquidity Facility
shall not have been so extended or replaced in accordance with Section 3.6(e),
or if the Liquidity Provider fails irrevocably and unconditionally to advise the
Subordination Agent on or before the date on which such Consent Period ends that
such Stated Expiration Date shall be so extended, the Subordination Agent shall,
on the date on which such Consent Period ends (or as soon as possible
thereafter), in accordance with and to the extent permitted by the terms of the
expiring Liquidity Facility (a "NON-EXTENDED FACILITY"), request a drawing under
such expiring Liquidity Facility (such drawing, a "NON-EXTENSION DRAWING") of
all available and undrawn amounts thereunder. Amounts drawn pursuant to any
Non-Extension Drawing shall be maintained and invested in accordance with
Section 3.6(f) hereof.

                  (e) ISSUANCE OF REPLACEMENT LIQUIDITY FACILITY. At any time,
the Subordination Agent may, at its option, in consultation with Northwest,
arrange for a Replacement Liquidity Facility to replace the Liquidity Facility
for any applicable Class of Certificates; PROVIDED HOWEVER, that, the initial
Liquidity Provider may not be replaced by Northwest as a Liquidity Provider with
respect to such Liquidity Facility prior to the third anniversary of the Closing
Date, unless there shall have become due to the initial Liquidity Provider
amounts pursuant to Section 3.01, 3.02 or 3.03 of the Liquidity Facilities and
the replacement of the initial Liquidity Provider would reduce or eliminate the
obligation to pay such amounts, any Liquidity Facility of such initial Liquidity
Provider shall have become a Downgraded Facility or a Non-Extended Facility or a
Downgrade Drawing or a Non-Extension Drawing shall have occurred under any
Liquidity Facility of such initial Liquidity Provider or such initial Liquidity
Provider shall have breached any of its payment (including, without limitation,
funding) obligations under any Liquidity Facility in respect of which it is the
Liquidity Provider; PROVIDED FURTHER that, the Liquidity Provider may arrange,
or the Subordination Agent (in consultation with Northwest) may arrange,


                                      -37-
<Page>

for a Replacement Liquidity Provider pursuant to paragraphs (c) and (d) of this
Section 3.6. In any such consultation, the Subordination Agent shall accept the
recommendations of Northwest in the absence of a good faith reason not to do so.
In addition, so long as Helaba is the Liquidity Provider for any Liquidity
Facility, at any time after a Non-Extension Drawing has been made under any
Liquidity Facility or at any time after Helaba has extended the Stated
Expiration Date under any such Liquidity Facility to the date that is 15 days
after the applicable Final Legal Distribution Date in accordance with the
provisions of such Liquidity Facility, the Liquidity Provider thereunder may, at
its option, arrange for a Replacement Liquidity Facility to replace the
Liquidity Facility under which such Non-Extension Drawing has been made or under
which the Stated Expiration Date has been so extended. No such Replacement
Liquidity Facility executed in connection therewith shall become effective and
no such Replacement Liquidity Facility shall be deemed a "Liquidity Facility"
under the Operative Agreements, unless and until (i) the conditions referred to
in the immediately following paragraph shall have been satisfied and (ii) if
such Replacement Liquidity Facility shall materially adversely affect the
rights, remedies, interests or obligations of the Class A-1 Certificateholders,
the Class A-2 Certificateholders, the Class B Certificateholders or the Class C
Certificateholders under any of the Operative Agreements, the applicable Trustee
shall have consented, in writing, to the execution and issuance of such
Replacement Liquidity Facility.

                  In connection with the issuance of each Replacement Liquidity
Facility, the Subordination Agent shall (x) prior to the issuance of such
Replacement Liquidity Facility, obtain written confirmation from each Rating
Agency that such Replacement Liquidity Facility will not cause a reduction of
the rating then in effect for any Class of Certificates by such Rating Agency
(without regard to any downgrading of the ratings of any Liquidity Provider
being replaced pursuant to Section 3.6(c) hereof), (y) pay all Liquidity
Obligations then owing to the replaced Liquidity Provider (which payment shall
be made first from available funds in the Cash Collateral Account as described
in clause (ix) of Section 3.6(f) hereof and thereafter from any other available
source, including, without limitation, a drawing under the Replacement Liquidity
Facility, it being understood that no Replacement Liquidity Facility shall
become effective (other than insofar as necessary to permit the repayment of
amounts owed to the replaced Liquidity Provider) until all amounts owed to the
replaced Liquidity Provider have been paid) and (z) cause the issuer of the
Replacement Liquidity Facility to deliver the Replacement Liquidity Facility to
the Subordination Agent, together with a legal opinion opining that such
Replacement Liquidity Facility is an enforceable obligation of such Replacement
Liquidity Provider. Upon satisfaction of the conditions set forth in this
Section 3.6(e), (i) the replaced Liquidity Facility shall terminate and (ii)
such Replacement Liquidity Provider shall be deemed to be a Liquidity Provider
with the rights and obligations of a Liquidity Provider hereunder and under the
other Operative Agreements and such Replacement Liquidity Facility shall be
deemed to be a Liquidity Facility hereunder and under the other Operative
Agreements.

                  (f) CASH COLLATERAL ACCOUNTS; WITHDRAWALS; INVESTMENTS. In the
event the Subordination Agent shall draw all available amounts under the Class
A-1 Liquidity Facility, the Class A-2 Liquidity Facility, the Class B Liquidity
Facility or the Class C Liquidity Facility pursuant to Section 3.6(c), 3.6(d) or
3.6(i), amounts so drawn shall be deposited by the Subordination Agent in the
Class A-1 Cash Collateral Account, the Class A-2 Cash Collateral Account, the
Class B Cash Collateral Account or the Class C Cash Collateral Account,
respectively. Amounts so deposited shall be invested in Eligible Investments in
accordance with


                                      -38-

Section 2.2(b) hereof. On each Interest Payment Date (or, in the case of any
Special Distribution Date occurring prior to the occurrence of a Triggering
Event, on such Special Distribution Date), Investment Earnings on amounts on
deposit in each Cash Collateral Account (or in the case of any Special
Distribution Date occurring prior to the occurrence of a Triggering Event, an
amount of such Investment Earnings on amounts of deposits in each Cash
Collateral Account equal to the product of such Investment Earnings multiplied
by a fraction, the numerator of which is the aggregate outstanding principal
amount of Equipment Notes being redeemed, purchased or prepaid on such Special
Distribution Date and the denominator of which is the aggregate outstanding
principal amount of all Equipment Notes) shall be deposited in the Collection
Account (or, in the case of any Special Distribution Date occurring prior to the
occurrence of a Triggering Event, the Special Payments Account) and applied on
such Interest Payment Date (or Special Distribution Date, as the case may be) in
accordance with Section 2.4(b), 3.2, 3.3 or 3.4(b) (as applicable). The
Subordination Agent shall deliver a written statement to the respective
Liquidity Provider one day prior to each Interest Payment Date and Special
Distribution Date setting forth the aggregate amount of Investment Earnings held
in the applicable Cash Collateral Accounts as of such date. In addition, from
and after the date funds are so deposited, the Subordination Agent shall make
withdrawals from such account as follows:

                  (i) on each Distribution Date, the Subordination Agent shall,
            to the extent it shall not have received funds to pay accrued and

            Interest Rate for the Class A-1 Certificates) from any other source,
            withdraw from the Class A-1 Cash Collateral Account, and pay to the
            Class A-1 Trustee an amount equal to the lesser of (x) an amount
            necessary to pay accrued and unpaid interest (at the Stated Interest
            Rate for the Class A-1 Certificates) on such Class A-1 Certificates
            and (y) the amount on deposit in the Class A-1 Cash Collateral
            Account;

            Class A-2 Trustee an amount equal to the lesser of (x) an amount

            Rate for the Class A-2 Certificates) on such Class A-2 Certificates
            and (y) the amount on deposit in the Class A-2 Cash Collateral
            Account;

            Interest Rate for the Class B Certificates) from any other source,
            withdraw from the Class B Cash Collateral Account, and pay to the
            Class B Trustee an amount equal to the lesser of (x) an amount
            necessary to pay accrued and unpaid interest (at the Stated Interest
            Rate for the Class B Certificates) on such Class B Certificates and
            (y) the amount on deposit in the Class B Cash Collateral Account;

                  (iv) on each Distribution Date, the Subordination Agent shall,
            to the extent it shall not have received funds to pay accrued and
            unpaid interest on the Class C Certificates (at the Stated Interest
            Rate for the Class C Certificates) from any other


                                      -39-

Facility shall not be so reinstated in part or in full at any time if (x) both a
Performing Note Deficiency exists and a Liquidity Event of Default shall have
occurred and be continuing with respect to the relevant Liquidity Facility or
(y) a Final Drawing shall have occurred with respect to such Liquidity Facility.
In the event that, with respect to any particular Liquidity Facility, (i) funds
are


                                      -41-
<Page>

withdrawn from any Cash Collateral Account pursuant to clause (i), (ii), (iii)
or (iv) of Section 3.6(f) or (ii)such Liquidity Facility shall become a
Downgraded Facility or a Non-Extended Facility at a time when unreimbursed

on which the Required Amount of the Liquidity Facility for a Class of
Certificates is reduced as a result of a distribution to the Certificateholders
of such Class of Certificates, the Subordination Agent shall, if such Liquidity
Facility provides for reductions of the Stated Amount of such Liquidity Facility
and if such reductions are not automatic, request the Liquidity Provider for
such Class of Certificates to reduce such Stated Amount to an amount equal to
the Required Amount with respect to such Liquidity Facility (as calculated by
the Subordination Agent after giving effect to such payment). Each such request
shall be made in accordance with the provisions of the applicable Liquidity
Facility.

                  (k) RELATION TO SUBORDINATION PROVISIONS. Interest Drawings
under the Liquidity Facilities and withdrawals from the Cash Collateral

                              EXERCISE OF REMEDIES

                  Section 4.1. DIRECTIONS FROM THE CONTROLLING PARTY. (a) (i)
Following the occurrence and during the continuation of an Indenture Default
under any Indenture, the Controlling Party shall direct the Loan Trustee under
such Indenture in the exercise of remedies available to the holders of the
Equipment Notes issued pursuant to such Indenture, including, without
limitation, the ability to vote all such Equipment Notes in favor of declaring
all of the unpaid principal amount of such Equipment Notes and accrued and
unpaid interest thereon to be due and payable under, and in accordance with, the
provisions of such Indenture. Subject to the


                                      -42-
<Page>

Owner Trustees' and the Owner Participants' rights, if any, set forth in the
Indentures with respect to Leased Aircraft to purchase the Equipment Notes, if
the Equipment Notes issued pursuant to any Indenture have been Accelerated
following an Indenture Default with respect thereto, the Controlling Party may
sell, assign, contract to sell or otherwise dispose of and deliver all (but not
less than all) of such Equipment Notes to any Person at public or private sale,
at any location at the option of the Controlling Party, all upon such terms and
conditions as it may reasonably deem advisable in accordance with applicable
law.

                  (ii) Subject to the Owner Trustees' and the Owner
Participants' rights set forth in the Indentures with respect to Leased Aircraft
to purchase the Equipment Notes, and notwithstanding the foregoing, so long as
any Certificates remain Outstanding, during the period ending on the date which
is nine months after the earlier of (x) the Acceleration of the Equipment Notes
issued pursuant to any Indenture or (y) the occurrence of a Northwest Bankruptcy
Event, without the consent of each Trustee (other than the Trustee of any Trust
all of the Certificates of which are held or beneficially owned by Northwest
and/or its Affiliates), (A) no Aircraft subject to the Lien of such Indenture or
such Equipment Notes may be sold if the net proceeds from such sale would be
less than the Minimum Sale Price for such Aircraft or such Equipment Notes, and
(B) with respect to any Leased Aircraft, the amount and payment dates of rentals
payable by Northwest under the Lease for such Aircraft may not be adjusted, if,
as a result of such adjustment, the discounted present value of all such rentals
would be less than 75% of the discounted present value of the rentals payable by
Northwest under such Lease before giving effect to such adjustment, in each
case, using the weighted average interest rate of the Equipment Notes issued
pursuant to such Indenture as the discount rate.

                  (iii) At the request of the Controlling Party, the
Subordination Agent may from time to time during the continuance of an Indenture
Default (and before the occurrence of a Triggering Event) commission LTV
Appraisals with respect to the related Aircraft.

                  (iv) After a Triggering Event occurs and any Equipment Note
becomes a Non-Performing Equipment Note, the Subordination Agent shall obtain
LTV Appraisals for all of the Aircraft as soon as practicable and additional LTV
Appraisals on or prior to each anniversary of the date of such initial LTV
Appraisals; PROVIDED that, if the Controlling Party reasonably objects to the
appraised value of the Aircraft shown in any such LTV Appraisals, the
Controlling Party shall have the right to obtain or cause to be obtained at its
expense substitute LTV Appraisals (including any LTV Appraisals based upon
physical inspection of the Aircraft).

                  (b) The Controlling Party shall take such actions as it may
reasonably deem most effectual to complete the sale or other disposition of such
Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment,
contract to sell or other disposition, the Subordination Agent, on behalf of the
Controlling Party, may maintain possession of such Equipment Notes and continue
to apply monies received in respect of such Equipment Notes in accordance with
Article III hereof. In addition, in lieu of such sale, assignment, contract to
sell or other disposition, or in lieu of such maintenance of possession, the
Controlling Party may instruct the Loan Trustee under such Indenture to
foreclose on the Lien on the related Aircraft or to take any other remedial
action permitted under such Indenture or applicable law.

and remedy given to the Trustees, the Liquidity Providers, the Controlling Party

cumulative and shall be in addition to every other right, power and remedy
herein specifically given or now or hereafter existing at law, in equity or by
statute, and each and every right, power and remedy whether specifically herein
given or otherwise existing may, subject always to the terms and conditions
hereof, be exercised from time to time and as often and in such order as may be
deemed expedient by any Trustee, any Liquidity Provider, the Controlling Party
or the Subordination Agent, as appropriate, and the exercise or the beginning of
the exercise of any power or remedy shall not be construed to be a waiver of the
right to exercise at the same time or thereafter any other right, power or
remedy. No delay or omission by any Trustee, any Liquidity Provider, the
Controlling Party or the Subordination Agent in the exercise of any right,
remedy or power or in the pursuit of any remedy shall impair any such right,
power or remedy or be construed to be a waiver of any default or to be an
acquiescence therein.

                  Section 4.3. DISCONTINUANCE OF PROCEEDINGS. In case any party
to this Agreement (including the Controlling Party in such capacity) shall have
instituted any Proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, entry or otherwise, and such Proceeding shall have
been discontinued or abandoned for any reason or shall have been determined
adversely to the Person instituting such Proceeding, then and in every such case
each such party shall, subject to any determination in such Proceeding, be
restored to its former position and rights hereunder, and all rights, remedies
and powers of such party shall continue as if no such Proceeding had been
instituted.

                  Section 4.4. RIGHT OF CERTIFICATEHOLDERS TO RECEIVE PAYMENTS
NOT TO BE IMPAIRED. Anything in this Agreement to the contrary notwithstanding
but subject to each Trust Agreement, the right of any Certificateholder or any
Liquidity Provider, respectively, to receive payments hereunder (including,
without limitation, pursuant to Section 2.4, 3.2 or 3.3 hereof) when due, or to
institute suit for the enforcement of any such payment on or after the
applicable Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder or such Liquidity Provider, respectively.

                  Section 4.5. UNDERTAKING FOR COSTS. In any suit for the

                       DUTIES OF THE SUBORDINATION AGENT;
                          AGREEMENTS OF TRUSTEES, ETC.

                  Section 5.1. NOTICE OF INDENTURE DEFAULT OR TRIGGERING EVENT.
(a) In the event the Subordination Agent shall have actual knowledge of the
occurrence of an Indenture Default or a Triggering Event, as promptly as
practicable, and in any event within 10 days after obtaining knowledge thereof,
the Subordination Agent shall transmit by mail or courier to the Rating
Agencies, the Liquidity Providers and the Trustees notice of such Indenture
Default or Triggering Event, unless such Indenture Default or Triggering Event
shall have been cured or waived. For all purposes of this Agreement, in the
absence of actual knowledge on the part of a Responsible Officer, the
Subordination Agent shall not be deemed to have knowledge of any Indenture
Default or Triggering Event unless notified in writing by one or more Trustees,
one or more Liquidity Providers or one or more Certificateholders.

                  (b) OTHER NOTICES. The Subordination Agent will furnish to
each Liquidity Provider and Trustee, promptly upon receipt thereof, duplicates
or copies of all reports, notices, requests, demands, certificates, financial
statements and other instruments furnished to the Subordination Agent as
registered holder of the Equipment Notes or otherwise in its capacity as
Subordination Agent to the extent the same shall not have been otherwise
directly distributed to such Liquidity Provider or Trustee, as applicable,
pursuant to the express provision of any other Operative Agreement.

                  Section 5.2. INDEMNIFICATION. The Subordination Agent shall
not be required to take any action or refrain from taking any action under
Section 5.1 (other than the first sentence thereof) or Article IV hereof unless
the Subordination Agent shall have been indemnified (to the extent and in the
manner reasonably satisfactory to the Subordination Agent) against any
liability, cost or expense (including counsel fees and expenses) which may be
incurred in connection therewith. The Subordination Agent shall not be under any
obligation to take any action under this Agreement and nothing contained in this
Agreement shall require the Subordination Agent to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its
duties hereunder or in the exercise of any of its rights or powers if it shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. The
Subordination Agent shall not be required to take any action under Section 5.1
(other than the first sentence thereof) or Article IV hereof, nor shall any
other provision of this Agreement be deemed to impose a duty on the
Subordination Agent to take any action, if the Subordination Agent shall have
been advised by counsel that such action is contrary to the terms hereof or is
otherwise contrary to law.

                  Section 5.3. NO DUTIES EXCEPT AS SPECIFIED IN INTERCREDITOR
AGREEMENT. The Subordination Agent shall not have any duty or obligation to take
or refrain from taking any action under, or in connection with, this Agreement,
except as expressly provided by the terms of this Agreement; and no implied
duties or obligations shall be read into this Agreement against the
Subordination Agent. The Subordination Agent agrees that it will, in its
individual capacity and at its own cost and expense (but without any right of
indemnity in respect of any such cost or


                                      -45-
<Page>

expense under Section 5.2 or 7.1 hereof) promptly take such action as may be
necessary to duly discharge all Liens on any of the Trust Accounts or any monies
deposited therein which result from claims against it in its individual capacity
not related to its activities hereunder or from a breach of its obligations that
constitute willful misconduct or gross negligence hereunder or any other
Operative Agreement.

                  Section 5.4. NOTICE FROM THE LIQUIDITY PROVIDERS AND TRUSTEES.
If a Responsible Officer of any Liquidity Provider or Trustee has actual notice
of an Indenture Default or a Triggering Event, such Person shall promptly use
its best efforts to give notice thereof to all other Liquidity Providers and
Trustees and to the Subordination Agent, PROVIDED, HOWEVER, that no such Person
shall have any liability hereunder as a result of its failure to deliver any
such notice.


                                   ARTICLE VI

                             THE SUBORDINATION AGENT

                  Section 6.1. AUTHORIZATION; ACCEPTANCE OF TRUSTS AND DUTIES.
Each of the Class A-1 Trustee, Class A-2 Trustee, Class B Trustee and Class C
Trustee hereby designates and appoints the Subordination Agent as the agent and
trustee of such Trustee under the applicable Liquidity Facility and authorizes
the Subordination Agent to enter into the applicable Liquidity Facility as agent
and trustee for such Trustee. Each of the Liquidity Providers and the Trustees
hereby designates and appoints the Subordination Agent as the Subordination
Agent under this Agreement.

                  The Subordination Agent hereby accepts the duties hereby
created and applicable to it as the Subordination Agent and agrees to perform
the same but only upon the terms of this Agreement and agrees to receive and
disburse all monies received by it in accordance with the terms hereof. The
Subordination Agent shall not be answerable or accountable under any
circumstances, except (a) for its own willful misconduct or gross negligence or,
with respect to the handling or transfer of funds, ordinary negligence, (b) as
provided in Section 2.2 or 5.3 hereof and (c) for liabilities that may result
from the material inaccuracy of any representation or warranty of the
Subordination Agent made in its individual capacity in any Operative Agreement.
The Subordination Agent shall not be liable for any error of judgment made in
good faith by a Responsible Officer of the Subordination Agent, unless it is
proved that the Subordination Agent was negligent in ascertaining the pertinent
facts.

                  Section 6.2. ABSENCE OF DUTIES. The Subordination Agent shall
have no duty to see to any recording or filing of this Agreement or any other
document, or to see to the maintenance of any such recording or filing.

                  Section 6.3. NO REPRESENTATIONS OR WARRANTIES AS TO DOCUMENTS.
The Subordination Agent in its individual capacity does not make nor shall be
deemed to have made any representation or warranty as to the validity, legality
or enforceability of this Agreement or any other Operative Agreement or as to
the correctness of any statement contained in any thereof, except for the
representations and warranties of the Subordination Agent, made in its
individual capacity, under any Operative Agreement to which it is a party. The


                                      -46-
<Page>

Certificateholders, the Trustees and the Liquidity Providers make no
representation or warranty hereunder whatsoever.

                  Section 6.4. NO SEGREGATION OF MONIES; NO INTEREST. Any monies
paid to or retained by the Subordination Agent pursuant to any provision hereof
and not then required to be distributed to any Trustee or any Liquidity Provider
as provided in Articles II and III hereof need not be segregated in any manner
except to the extent required by such Articles II and III and by law, and the
Subordination Agent shall not (except as otherwise provided in Section 2.2
hereof) be liable for any interest thereon; PROVIDED, HOWEVER, that any payments
received or applied hereunder by the Subordination Agent shall be accounted for
by the Subordination Agent so that any portion thereof paid or applied pursuant
hereto shall be identifiable as to the source thereof.

                  Section 6.5. RELIANCE; AGENTS; ADVICE OF COUNSEL. The
Subordination Agent shall not incur liability to anyone in acting upon any
signature, instrument, notice, resolution, request, consent, order, certificate,
report, opinion, bond or other document or paper believed by it to be genuine
and believed by it to be signed by the proper party or parties. As to the Pool
Balance of any Trust as of any date, the Subordination Agent may for all
purposes hereof rely on a certificate signed by any Responsible Officer of the
applicable Trustee, and such certificate shall constitute full protection to the
Subordination Agent for any action taken or omitted to be taken by it in good
faith in reliance thereon. As to any fact or matter relating to the Liquidity
Providers or the Trustees the manner of ascertainment of which is not
specifically described herein, the Subordination Agent may for all purposes
hereof rely on a certificate, signed by any Responsible Officer of the
applicable Liquidity Provider or Trustee, as the case may be, as to such fact or
matter, and such certificate shall constitute full protection to the
Subordination Agent for any action taken or omitted to be taken by it in good
faith in reliance thereon. The Subordination Agent shall assume, and shall be
fully protected in assuming, that each of the Liquidity Providers and each of
the Trustees are authorized to enter into this Agreement and to take all action
to be taken by them pursuant to the provisions hereof, and shall not inquire
into the authorization of each of the Liquidity Providers and each of the
Trustees with respect thereto. In the administration of the trusts hereunder,
the Subordination Agent may execute any of the trusts or powers hereof and
perform its powers and duties hereunder directly or through agents or attorneys
and may consult with counsel, accountants and other skilled persons to be
selected and retained by it, and the Subordination Agent shall not be liable for
the acts or omissions of any agent appointed with due care or for anything done,
suffered or omitted in good faith by it in accordance with the advice or written
opinion of any such counsel, accountants or other skilled persons.

                  Section 6.6. CAPACITY IN WHICH ACTING. The Subordination Agent
acts hereunder solely as agent and trustee herein and not in its individual
capacity, except as otherwise expressly provided in the Operative Agreements.

                  Section 6.7. COMPENSATION. The Subordination Agent shall be
entitled to reasonable compensation, including expenses and disbursements, for
all services rendered hereunder and shall have a priority claim to the extent
set forth in Article III hereof on all monies collected hereunder for the
payment of such compensation, to the extent that such compensation shall not be
paid by others. The Subordination Agent agrees that it shall have no right
against


                                      -47-
<Page>

any Trustee or Liquidity Provider for any fee as compensation for its services
as agent under this Agreement. The provisions of this Section 6.7 shall survive
the termination of this Agreement.

                  Section 6.8. MAY BECOME CERTIFICATEHOLDER. The institution
acting as Subordination Agent hereunder may become a Certificateholder and have
all rights and benefits of a Certificateholder to the same extent as if it were
not the institution acting as the Subordination Agent.

                  Section 6.9. SUBORDINATION AGENT REQUIRED; ELIGIBILITY. There
shall at all times be a Subordination Agent hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America or of any State or the District of Columbia having a combined capital
and surplus of at least $100,000,000 (or the obligations of which, whether now
in existence or hereafter incurred, are fully and unconditionally guaranteed by
a corporation organized and doing business under the laws of the United States,
any State thereof or of the District of Columbia and having a combined capital
and surplus of at least $100,000,000), if there is such an institution willing
and able to perform the duties of the Subordination Agent hereunder upon
reasonable or customary terms. Such corporation shall be a citizen of the United
States and shall be authorized under the laws of the United States or any State
thereof or of the District of Columbia to exercise corporate trust powers and
shall be subject to supervision or examination by federal, state or District of
Columbia authorities. If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of any of the aforesaid
supervising or examining authorities, then, for the purposes of this Section
6.9, the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.

                  In case at any time the Subordination Agent shall cease to be
eligible in accordance with the provisions of this Section, the Subordination
Agent shall resign immediately in the manner and with the effect specified in
Section 8.1.

                  Section 6.10. MONEY TO BE HELD IN TRUST. All Equipment Notes,
monies and other property deposited with or held by the Subordination Agent
pursuant to this Agreement shall be held in trust for the benefit of the parties
entitled to such Equipment Notes, monies and other property. All such Equipment

institution acting as Subordination Agent hereunder.


                                   ARTICLE VII

Agreement. The indemnities contained in such Sections of such agreements shall
survive the termination of this Agreement.

                                  ARTICLE VIII

                          SUCCESSOR SUBORDINATION AGENT

                  Section 8.1. REPLACEMENT OF SUBORDINATION AGENT; APPOINTMENT
OF SUCCESSOR. The Subordination Agent may resign at any time by so notifying the
Trustees and the Liquidity Providers. The Liquidity Provider or the Controlling
Party may remove the Subordination Agent for cause by so notifying the
Subordination Agent and may appoint a successor Subordination Agent. The
Controlling Party shall remove the Subordination Agent if:

                  (1) the Subordination Agent fails to comply with Section 6.9
            hereof;

                  (2) the Subordination Agent is adjudged bankrupt or insolvent;

                  (3) a receiver or other public officer takes charge of the
            Subordination Agent or its property; or

                  (4) the Subordination Agent otherwise becomes incapable of
            acting.

                  If the Subordination Agent resigns or is removed or if a
vacancy exists in the office of Subordination Agent for any reason (the
Subordination Agent in such event being referred to herein as the retiring
Subordination Agent), the Controlling Party in consultation with Northwest shall
promptly appoint a successor Subordination Agent.

                  Any corporation into which the Subordination Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the
Subordination Agent shall be a party, or any corporation to which substantially
all the corporate trust business of the Subordination Agent may be transferred,
shall, subject to the terms of Section 6.9 hereof, be the Subordination Agent
hereunder and under the other Operative Agreements to which the Subordination
Agent is a party without further act, except that such Person shall give prompt
subsequent notice of such transaction to the Liquidity Provider and each
Trustee.

                  A successor Subordination Agent shall deliver (x) a written
acceptance of its appointment as Subordination Agent hereunder to the retiring
Subordination Agent and (y) a written assumption of its obligations hereunder
and under each Liquidity Facility, to each party hereto upon which the
resignation or removal of the retiring Subordination Agent shall become
effective, and the successor Subordination Agent shall have all the rights,
powers and duties of the Subordination Agent under this Agreement. The successor
Subordination Agent shall send a written notice of its succession to the
Liquidity Providers and the Trustees. The retiring Subordination Agent shall
promptly transfer its rights under each of the Liquidity Facilities and all of
the property held by it as Subordination Agent to the successor Subordination
Agent.

                  If a successor Subordination Agent does not take office within
60 days after the retiring Subordination Agent resigns or is removed, the
retiring Subordination Agent or one or more of the Trustees may petition any
court of competent jurisdiction for the appointment of a successor Subordination
Agent.

                  If the Subordination Agent fails to comply with Section 6.9
hereof (to the extent applicable), one or more of the Trustees or one or more of
the Liquidity Providers or Northwest may petition any court of competent
jurisdiction for the removal of the Subordination Agent and the appointment of a
successor Subordination Agent.

                  Notwithstanding the foregoing, no resignation or removal of
the Subordination Agent shall be effective unless and until a successor has been
appointed. No appointment of a successor Subordination Agent shall be effective
unless and until the Rating Agencies shall have delivered a Ratings
Confirmation.


                                   ARTICLE IX

                           SUPPLEMENTS AND AMENDMENTS

                  Section 9.1. AMENDMENTS, WAIVERS, ETC. (a) This Agreement may
not be supplemented, amended or modified without the consent of each Trustee
(acting, except in the case of any amendment pursuant to Section 9.5 hereof,
with the consent of holders of Certificates of the related Class evidencing
interests in the related Trust aggregating not less than a majority in interest
in such Trust or as otherwise authorized pursuant to the relevant Trust
Agreement), the Subordination Agent and each Liquidity Provider; PROVIDED,
HOWEVER, that this Agreement may be supplemented, amended or modified without
the consent of any Trustee if such supplement, amendment or modification (i) is
in accordance with Section 9.5 or (ii) cures an ambiguity or inconsistency or
does not materially adversely affect such Trustee or the holders of the related
Class of Certificates; PROVIDED FURTHER, HOWEVER, that, if such supplement,
amendment or modification would (x) directly or indirectly modify or supersede,
or otherwise conflict with, Section 2.2(b), Section 3.6(e), Section 3.6(f)(other
than the last sentence thereof) (collectively, together with this proviso and
Section 9.1, the "NORTHWEST PROVISIONS") or (y) otherwise adversely affect the
interests of a potential Replacement Liquidity Provider or of Northwest with
respect to its ability to replace any Liquidity Facility or with respect to its
payment obligations under any Financing Agreement, Leased Aircraft Indenture or
Owned Aircraft Indenture, then such supplement, amendment or modification shall
not be effective without the additional written consent of Northwest.
Notwithstanding the foregoing, without the consent of each Certificateholder and
each Liquidity Provider, no supplement, amendment or modification of this
Agreement may (i) reduce the percentage of the interest in any Trust evidenced
by the Certificates issued by such Trust necessary to consent to modify or amend
any provision of this Agreement or to waive compliance therewith or (ii) modify
Section 2.4, 3.2 or 3.3 hereof, relating to the distribution of monies received
by the Subordination Agent hereunder from the Equipment Notes or pursuant to the
Liquidity Facilities. Nothing contained in this Section shall require the
consent of a Trustee at any time following the payment of Final Distributions
with respect to the related Class of Certificates.

                  (b) In the event that the Subordination Agent, as the
registered holder of any Equipment Notes, receives a request for its consent to
any amendment, modification, consent or waiver under such Equipment Notes, the
Indenture pursuant to which such Equipment Notes were issued, or the related
Lease, Participation Agreement or other related document, (i) if no Indenture
Default shall have occurred and be continuing with respect to such Indenture,
the Subordination Agent shall request directions with respect to each Series of
such Equipment


                                      -50-
<Page>

Notes from the Trustee of the Trust which holds such Equipment Notes and shall
vote or consent in accordance with the directions of such Trustee and (ii) if
any Indenture Default (which, in the case of any Indenture pertaining to a
Leased Aircraft, has not been cured by the applicable Owner Trustee or the
applicable Owner Participant, if applicable, pursuant to Section 4.03 of such
Indenture) shall have occurred and be continuing with respect to such Indenture,
the Subordination Agent will exercise its voting rights as directed by the
Controlling Party, subject to Sections 4.1 and 4.4 hereof; provided that no such
amendment, modification or waiver shall, without the consent of each Liquidity
Provider, reduce the amount of rent, supplemental rent or stipulated loss values
payable by Northwest under any Lease or reduce the amount of principal or
interest payable by Northwest under any Equipment Note issued under any
Indenture in respect of an Owned Aircraft.

                  (c) Notwithstanding any provision to the contrary contained
herein, so long as Northwest and/or its Affiliates holds or beneficially owns a
majority of the Class D Certificates or otherwise controls the actions of the
Class D Trustee, any consent or approval of the Class D Trustee or any Class D
Certificateholder otherwise required in accordance with the foregoing provisions
shall not be required.

                  (d) If any additional series of equipment notes are issued
under any Indenture for a Boeing 747-400 Aircraft ("ADDITIONAL EQUIPMENT
NOTES"), this Agreement shall be amended by written agreement of the indenture
trustees of the Additional Equipment Notes, the Trustees and the Subordination
Agent to (i) provide for each holder of an Additional Equipment Note to be bound
by the provisions of Section 2.6(a) so that the Controlling Party, among other
things, shall be entitled to direct the Loan Trustee under the applicable
Indenture as provided in such Section 2.6(a) (and such Additional Equipment
Notes shall make effective provision therefor so as to bind each holder thereof
to such provisions of Section 2.6(a)) and (ii) to revise the definitions of
"CONTROLLING PARTY" and "EQUIPMENT NOTES", as appropriate, to reflect the
issuance of the Additional Equipment Notes (and the prior rights, as against the
holders of such Additional Equipment Notes, of the Class A-1 Trustee, the Class
A-2 Trustee, the Class B Trustee, the Class C Trustee and the Class D Trustee to
be such "Controlling Party"). No such amendment shall materially adversely
affect any Trustee.

                  Section 9.2. SUBORDINATION AGENT PROTECTED. If, in the
reasonable opinion of the institution acting as the Subordination Agent
hereunder, any document required to be executed pursuant to the terms of Section
9.1 affects any right, duty, immunity or indemnity with respect to it under this
Agreement or any Liquidity Facility, the Subordination Agent may in its
discretion decline to execute such document.

                  Section 9.3. EFFECT OF SUPPLEMENTAL AGREEMENTS. Upon the
execution of any amendment or supplement hereto pursuant to the provisions
hereof, this Agreement shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Agreement of the parties hereto
and beneficiaries hereof shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments, and all
the terms and conditions of any such supplemental agreement shall be and be
deemed to be part of the terms and conditions of this Agreement for any and all
purposes. In executing or accepting any supplemental agreement permitted by this
Article IX, the Subordination Agent shall be entitled to receive, and


                                      -51-
<Page>

shall be fully protected in relying upon, an opinion of counsel stating that the
execution of such supplemental agreement is authorized or permitted by this
Agreement.

                  Section 9.4. NOTICE TO RATING AGENCIES. Promptly following its
receipt of each amendment, consent, modification, supplement or waiver
contemplated by this Article IX, the Subordination Agent shall send a copy
thereof to each Rating Agency.

                  Section 9.5. ADDITION OF CLASS D TRUSTEE. If any Class D
Certificates are issued, this Agreement shall be amended by written agreement of
Northwest and the Subordination Agent to give effect to the issuance of any
Class D Certificates, which amendment shall include, without limitation,
provision for the Class D Trust Trustee to be added as a party to this Agreement
and for the definition of "Stated Interest Rate" to be revised, as appropriate,
to reflect the issuance of the Class D Certificates (and the subordination
thereof).

Following payment of Final Distributions with respect to each Class of
Certificates and the payment in full of all Liquidity Obligations to the
Liquidity Providers and PROVIDED that there shall then be no other amounts due
to the Certificateholders, the Trustees, the Liquidity Providers and the
Subordination Agent hereunder or under the Trust Agreements, and that the
commitment of the Liquidity Providers under the Liquidity Facilities shall have
expired or been terminated, this Agreement and the trusts created hereby shall

Trustees, the Liquidity Providers and the Subordination Agent any legal or
equitable right, remedy or claim under or in respect of this Agreement.

which is prohibited or unenforceable in any jurisdiction shall, as to such

                  Section 10.7. HEADINGS. The headings of the various Articles
and Sections herein and in the table of contents hereto are for convenience of
reference only and shall not define or limit any of the terms or provisions
hereof.

                  Section 10.8. COUNTERPART FORM. This Agreement may be executed
by the parties hereto in separate counterparts, each of which when so executed
and delivered shall be an original, but all such counterparts shall together
constitute but one and the same agreement.

                  Section 10.9. SUBORDINATION. (a) As between the Liquidity
Providers, on the one hand, and the Trustees and the Certificateholders, on the
other hand, and as between and among the Certificateholders of all Classes of
Certificates, this Agreement shall be a subordination agreement for purposes of
Section 510 of the United States Bankruptcy Code, as amended from time to time.

                  (b) Notwithstanding the provisions of this Agreement, if prior
to the payment in full to the Liquidity Providers of all Liquidity Obligations
then due and payable, any party hereto shall have received any payment or
distribution in respect of Equipment Notes or any other amount under the
Indentures or other Operative Agreements which, had the subordination provisions
of this Agreement been properly applied to such payment, distribution or other
amount, would not have been distributed to such Person, then such payment,
distribution or other amount shall be received and held in trust by such Person
and paid over or delivered to the Subordination Agent for application as
provided herein.

                  (c) If any Trustee, any Liquidity Provider or the
Subordination Agent receives any payment in respect of any obligations owing
hereunder (or, in the case of the Liquidity Providers, in respect of the
Liquidity Obligations), which is subsequently invalidated, declared
preferential, set aside and/or required to be repaid to a trustee, receiver or
other party, then, to the extent of such payment, such obligations (or, in the
case of the Liquidity Providers, such Liquidity Obligations) intended to be
satisfied shall be revived and continue in full force and effect as if such
payment had not been received.

                  (d) The Trustees (on behalf of themselves and the holders of
Certificates), the Liquidity Providers and the Subordination Agent confirm that
the payment priorities specified in Sections 2.4, 3.2 and 3.3 shall apply in all
circumstances, notwithstanding the fact that the obligations owed to the
Trustees and the holders of Certificates are secured by certain assets and the
Liquidity Obligations are not so secured. The Trustees expressly agree (on
behalf of themselves and the holders of Certificates) not to assert priority
over the holders of Liquidity Obligations due to their status as secured
creditors in any bankruptcy, insolvency or other legal proceeding.

                  (e) Each of the Trustees (on behalf of themselves and the
holders of Certificates), the Liquidity Providers and the Subordination Agent
may take any of the following actions without impairing its rights under this
Agreement:

                  (i) obtain a lien on any property to secure any amounts owing
            to it hereunder, including, in the case of the Liquidity Providers,
            the Liquidity Obligations,



                                      -54-
<Page>

                  (ii) obtain the primary or secondary obligation of any other
            obligor with respect to any amounts owing to it hereunder,
            including, in the case of the Liquidity Providers, any of the
            Liquidity Obligations,

                  (iii) renew, extend, increase, alter or exchange any amounts
            owing to it hereunder, including, in the case of the Liquidity
            Providers, any of the Liquidity Obligations, or release or
            compromise any obligation of any obligor with respect thereto,

                  (iv) refrain from exercising any right or remedy, or delay in
            exercising such right or remedy, which it may have, or

                  (v) take any other action which might discharge a subordinated
            party or a surety under applicable law;

PROVIDED, HOWEVER, that the taking of any such actions by any of the Trustees,
the Liquidity Providers or the Subordination Agent shall not prejudice the
rights or adversely affect the obligations of any other party under this
Agreement.

                  Section 10.10. GOVERNING LAW. THIS AGREEMENT SHALL IN ALL
RESPECTS BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE
OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

                  Section 10.11. SUBMISSION TO JURISDICTION; WAIVER OF JURY
TRIAL; WAIVER OF IMMUNITY. (a) Each of the parties hereto hereby irrevocably and
unconditionally:

                  (i) submits for itself and its property in any legal action or
            proceeding relating to this Agreement or any other Operative
            Agreement, or for recognition and enforcement of any judgment in
            respect hereof or thereof, to the nonexclusive general jurisdiction
            of the courts of the State of New York, the courts of the United
            States of America for the Southern District of New York, and the
            appellate courts from any thereof;

                  (ii) consents that any such action or proceeding may be
            brought in such courts, and waives any objection that it may now or
            hereafter have that the venue of any such action or proceeding was
            brought in an inconvenient court and agrees not to plead or claim
            the same;

                  (iii) agrees that service of process in any such action or
            proceeding may be effected by mailing a copy thereof by registered
            or certified mail (or any substantially similar form and mail),
            postage prepaid, to each party hereto at its address set forth in
            Section 10.3 hereof, or at such other address of which the other
            parties 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) EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE
SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED,
INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY
CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH OF THE PARTIES
WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL,
AND THAT IT KNOWINGLY AND 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, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

                  (c) Each Liquidity Provider hereby waives any immunity it may
have from the jurisdiction of the courts of the United States or of any state
thereof and waives any immunity any of its properties located in the United
States may have from attachment or execution upon a judgment entered by any such
court under the United States Foreign Sovereign Immunities Act of 1976 or any
similar successor legislation.
