          NOW, THEREFORE, in consideration of the foregoing premises and the
mutual agreements herein contained and other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged, the parties hereto
agree as follows:

          Section 1.  Definitions. Capitalized terms used but not defined
herein shall have the respective meanings set forth or incorporated by
reference in Annex A.

          Section 2.  Financing of Aircraft.  (a)  The Company confirms (i)
that it has purchased the Existing Aircraft and (ii) entered into the
Aircraft Purchase Agreement with the Seller pursuant to which it has agreed
to purchase or has purchased, and the Seller has agreed to deliver or has
delivered, the New Aircraft in the months specified in Schedule I hereto, all
on and subject to terms and conditions specified in the Aircraft Purchase
Agreement. The Company agrees to finance or refinance the Aircraft in the
manner provided herein, all on and subject to the terms and conditions hereof
and of the relevant Financing Agreements.

          (b)  In furtherance of the foregoing, the Company agrees to give
the parties hereto, each Depositary and each of the Rating Agencies not less
than two (2) Business Days' prior notice (a "Closing Notice") of the
scheduled closing date (the "Scheduled Closing Date") (or, in the case of a
Substitute Closing Notice under Section 2(f) or (g) hereof, one (1) Business
Day's prior notice) of a financing in respect of each Aircraft, which notice
shall:

          (i)  specify whether the Company has elected to treat such Aircraft
     as a Leased Aircraft or an Owned Aircraft;

          (ii)  specify the Scheduled Closing Date on which the financing
     therefor in the manner provided herein shall be consummated;

          (iii)  instruct the Pass Through Trustees to instruct each Escrow
     Agent to provide a Notice of Purchase Withdrawal to the Depositary with
     respect to the Equipment Notes to be issued in connection with the
     financing of such Aircraft;



                                      -3-

<PAGE>

          (iv)  instruct the Pass Through Trustees to enter into the
     Participation Agreement with respect to such Aircraft in such form and
     at such a time on or before the Scheduled Closing Date specified in such
     Closing Notice and to perform its obligations thereunder;

          (v)  specify the aggregate principal amount of each series of
     Equipment Notes to be issued, and purchased by the Pass Through
     Trustees, in connection with the financing of such Aircraft on such
     Scheduled Closing Date (which shall in all respects comply with the
     Mandatory Economic Terms); and

          (vi)  if such Aircraft is to be a Leased Aircraft, certify that the
     related Owner Participant (A) is not an Affiliate of the Company and (B)
     based on the representations of such Owner Participant, is either (1) a
     Qualified Owner Participant or (2) any other person the obligations of
     which under the Owner Participant Documents (as defined in the
     applicable Participation Agreement) are guaranteed by a Qualified Owner
     Participant.

          Notwithstanding the foregoing, in the event the Scheduled Closing
Date for any Aircraft to be financed or refinanced pursuant to the terms
hereof is on or within 3 Business Days following the date of issuance of the
Certificates, the Closing Notice therefor may be delivered to the parties
hereto on such Scheduled Closing Date.

          (c)  Upon receipt of a Closing Notice, the Pass Through Trustees
shall, and shall cause the Subordination Agent to, enter into and perform
their obligations under the Participation Agreement specified in such Closing
Notice, provided, however, that such Participation Agreement and the other
Financing Agreements to be entered into pursuant to such Participation
Agreement shall be in the forms thereof annexed hereto in all material
respects with such changes therein as shall have been requested by the
related Owner Participant (in the case of Lease Financing Agreements), agreed
to by the Company and, if modified in any material respect, as to which prior
written consent of the Policy Provider shall have been obtained and as to
which Rating Agency Confirmation shall have been obtained from each Rating
Agency by the Company (to be delivered by the Company to the applicable Pass
Through Trustee and the Policy Provider on or before the relevant Closing
Date, it being understood that if Policy Provider consent and Rating Agency
Confirmation shall have been received with respect to any Financing
Agreements and such Financing Agreements are utilized for subsequent Aircraft
(or Substitute Aircraft) without material modifications, no additional Policy
Provider consent or Rating Agency Confirmation shall be required); provided,
however, that the relevant Financing Agreements as executed and delivered
shall not vary the Mandatory Economic Terms and shall contain the Mandatory
Document Terms (as such Mandatory Document Terms may be modified in
accordance with Schedule V hereto). Notwithstanding the foregoing, if any

                                      -4-

<PAGE>

Financing Agreement annexed hereto shall not have been reviewed by either
Rating Agency prior to the Issuance Date, then, prior to the use thereof in
connection with the financing of any Aircraft hereunder, the Company shall
obtain from each Rating Agency a confirmation that the use of such Financing
Agreement would not result in (A) a reduction of the rating for any Class of
Certificates below the then current rating for such Class of Certificates
(without regard to the Policy) or (B) a withdrawal or suspension of the
rating of any Class of Certificates, in each case, without reference to the
Policy.

          (d)  With respect to each Aircraft, the Company shall cause (i)
State Street Bank and Trust Company (or such other person that meets the
eligibility requirements to act as loan trustee under the Leased Aircraft
Indenture or Owned Aircraft Indenture) to execute as Loan Trustee the
Financing Agreements relating to such Aircraft to which such Loan Trustee is
intended to be a party and (ii) Northwest Airlines Corporation to execute a
Guarantee, and shall concurrently therewith execute such Financing Agreements
to which the Company is intended to be a party and perform its respective
obligations thereunder. Upon the request of the Policy Provider or either
Rating Agency, the Company shall deliver or cause to be delivered to the
Policy Provider or each Rating Agency, as the case may be, a true and
complete copy of each Financing Agreement relating to the financing of each
Aircraft together with a true and complete set of the closing documentation
(including legal opinions) delivered to the related Loan Trustee,
Subordination Agent and Pass Through Trustee under the related Participation
Agreement.

          (e)  If after giving any Closing Notice, there shall be a delay in
the delivery of a New Aircraft, or if on the Scheduled Closing Date of any
Aircraft the financing thereof in the manner contemplated hereby shall not be
consummated for whatever reason, the Company shall give the parties hereto
and the Policy Provider prompt notice thereof. Concurrent with the giving of
such notice of postponement or subsequent thereto, the Company shall give the
parties hereto and the Policy Provider a substitute Closing Notice specifying
the date (the "Substitute Closing Date") to which the applicable financing
shall have been rescheduled, which shall be a Business Day before the Cut-Off
Date on which the Escrow Agents shall be entitled to withdraw one or more
Deposits under each of the applicable Deposit Agreements to enable each
applicable Pass Through Trustee to fund its purchase of the related Equipment
Notes.  Upon receipt of any such notice of postponement, each applicable Pass
Through Trustee shall comply with its obligations under Article IV of each of
the Trust Supplements and thereafter the financing or refinancing of the
relevant Aircraft shall take place on the Substitute Closing Date therefor
(all on and subject to the terms and conditions of the relevant Financing
Agreements) unless further postponed as provided herein.



                                      -5-

          (f)  Anything in this Section 2 to the contrary notwithstanding,
the Company shall have the right at any time on or before the Scheduled
Closing Date of any Aircraft, and subsequent to its giving a Closing Notice
therefor, to postpone the Scheduled Closing Date of such Aircraft so as to
enable the Company to change its election to treat such Aircraft as a Leased
Aircraft or an Owned Aircraft by written notice of such postponement to the
other parties hereto. The Company shall subsequently give the parties hereto
a substitute Closing Notice complying with the provisions of Section 2(b)
hereof and specifying the new Closing Date for such postponed Aircraft (which
shall be a Business Day occurring before the Cut-Off Date and on which the
Escrow Agents shall be entitled to withdraw Deposits under each of the
applicable Deposit Agreements sufficient to enable each applicable Pass
Through Trustee to fund its purchase of the related Equipment Notes). In
addition the Company shall have the further right, anything in this Section 2
to the contrary notwithstanding, to accept delivery of a New Aircraft under
the Aircraft Purchase Agreement on the Closing Date thereof by utilization of
bridge financing of such New Aircraft and thereafter give the parties hereto
a Closing Notice specifying a Closing Date no later than the Cut-Off Date and
otherwise complying with the provisions of Section 2(b) hereof. All other
terms and conditions of this Note Purchase Agreement shall apply to the
financing of any such Aircraft on the re-scheduled Closing Date therefor
except the re-scheduled Closing Date shall be deemed the Closing Date of such
Aircraft for all purposes of this Section 2.

          (g)  Anything in this Section 2 to the contrary notwithstanding,
the Company shall have the right at any time to convert an Owned Aircraft to
a Leased Aircraft by entering into a sale/leaseback transaction; provided,
that, prior to, or concurrent with, such conversion, the Company must (i)
comply with the conditions set forth in the Leased Aircraft Participation
Agreement with respect to such aircraft, (ii) deliver an opinion of counsel
that holders of Certificates related to such Aircraft will not recognize
income, gain or loss for federal income tax purposes as a result of such
conversion and will be subject to federal income tax in the same amount and
in the same manner and at the same time as would have been the case if such
conversion had not occurred  (other than such change in amount, manner and
timing of interest  that results from any reoptimization of the Equipment
Notes permitted pursuant to Section 16 of the applicable Owned Aircraft
Participation Agreement in connection with such conversion) and that the Pass
Through Trusts will not be subject to federal income tax as a result of such
conversion and (iii) obtain Rating Agency Confirmation. If the delivery date
for any New Aircraft under the Aircraft Purchase Agreement is delayed for
more than 30 days beyond the month scheduled for delivery or beyond the
Cut-Off Date, the Company may identify for delivery a substitute aircraft
therefor meeting the following conditions (together with the substitute
aircraft referred to in the next sentence, a "Substitute Aircraft"): (i) a
Substitute Aircraft must be an Airbus Model A319-100 aircraft delivered by
the Seller to the Company after the date of this Agreement, (ii) the

                                      -6-

<PAGE>

Substitute Aircraft must have been manufactured after the Issuance Date and
(iii) the Company shall be obligated to obtain prior written consent of the
Policy Provider and Rating Agency Confirmation in respect of the replacement
of any New Aircraft by Substitute Aircraft.  Upon the satisfaction of the
conditions set forth above with respect to a Substitute Aircraft, the New
Aircraft to be replaced shall cease to be subject to this Agreement and all
rights and obligations of the parties hereto concerning such New Aircraft
shall cease, and such Substitute Aircraft shall become and thereafter be
subject to the terms and conditions of this Agreement to the same extent as
such New Aircraft.

          (h)  The Company shall have no liability for the failure of the
Pass Through Trustees to purchase Equipment Notes with respect to any
Aircraft or Substitute Aircraft, other than the Company's obligation, if any,
to pay the Deposit Make-Whole Amount pursuant to Section 5(a)(i) of this
Agreement.

          (i)  The parties agree that if, in connection with the delivery of
an Aircraft or a Substitute Aircraft or the conversion of an Owned Aircraft
to a Leased Aircraft, any Owner Participant who is to be a party to any Lease
Financing Agreements shall not be a "citizen of the United States" within the
meaning of 49 U.S.C. Section 40102 (a)(15), then the applicable Lease
Financing Agreements shall be modified, consistent with the Mandatory
Document Terms (as such Mandatory Document Terms may be modified in
accordance with Schedule V hereto), to require such Owner Participant to
enter into a voting trust, voting powers or similar arrangement satisfactory
to the Company that (A) enables such Aircraft or Substitute Aircraft to be
registered in the United States and (B) complies with the FAA regulations
issued under the Act applicable thereto.

          (j)  Anything herein to the contrary notwithstanding, the Company
shall not have the right, and shall not be entitled, at any time to request
the issuance of Equipment Notes of any series to any Pass Through Trustee in
an aggregate principal amount in excess of the amount of the Deposits then
available for withdrawal by the Escrow Agent under and in accordance with the
provisions of the related Deposit Agreement.

          (k)  The Company shall notify the Rating Agencies and the Policy
Provider in writing of any lease of an Owned Aircraft pursuant to the terms
of an Owned Aircraft Indenture promptly after entering into such lease.

          Section 3.  Conditions Precedent. The obligation of the Pass
Through Trustees to enter into, and to cause the Subordination Agent to enter
into, any Participation Agreement as directed pursuant to a Closing Notice
and to perform its obligations under such Participation Agreement is subject
to satisfaction of the following conditions:


                                      -7-

<PAGE>

          (a)  no Triggering Event shall have occurred;

          (b)  the Company shall have delivered a certificate to each such
Pass Through Trustee, each Liquidity Provider and the Policy Provider
stating that (i) such Participation Agreement and the other Financing
Agreements to be entered into pursuant to such Participation Agreement do not
vary the Mandatory Economic Terms and contain the Mandatory Document Terms
(as such Mandatory Document Terms may be modified in accordance with Schedule
V hereto) and (ii) any substantive modification of such Financing Agreements
from the forms thereof attached to this Agreement do not materially and
adversely affect the Liquidity Provider or the Certificate Holders or the
Policy Provider, and such certification shall be true and correct; and

          (c)  if required by Section 2(c) and in place of the statement in
clause (ii) of Section 3(b) above, Rating Agency Confirmation from each
Rating Agency and Policy Provider consent.

          Anything herein to the contrary notwithstanding, the obligation of
each Pass Through Trustee to purchase Equipment Notes shall terminate on the
Cut-Off Date.

          Section 4.  Representations and Warranties.

          (a)  The Company represents and warrants on the date hereof and on
each Closing Date that:

          Section 5.  Covenants.  (a)  The Company covenants with each of the
other parties hereto that:

          (i)  on the date that the Depositary is obligated to pay the amount
     of the Final Withdrawal to the Paying Agent pursuant to a Deposit
     Agreement relating to any Trust, the Company shall pay to the Pass
     Through Trustee of such Trust no later than 1:00 p.m. (New York time) an
     amount equal to the Deposit Make-Whole Amount, if any, required to be
     paid in respect of such Final Withdrawal amount;

          (ii)  subject to Section 5(a)(iv) of this Agreement, the Company
     shall at all times maintain its corporate existence and shall not wind

     are initially issued to other than the pass through trustee for the
     Class D Certificates, the Company will cause such Series D Equipment
     notes to be subject to the provisions of the Intercreditor Agreement
     that allow the "Controlling Party" (as defined in the Intercreditor
     Agreement), during the continuance of an "Indenture Default" (as defined

          (vi)  If the Depositary's short-term rating shall at any time fall
     below the Depositary Threshold Rating from either Moody's or Standard &

     the Depositary to be replaced with a depositary bank (a "Replacement
     Depositary") on the following terms and conditions:

               (1)  the Replacement Depositary must be one that either (x)
          meets the Depositary Threshold Rating or (y) with respect to which
          the Company shall have obtained written confirmation from each
          Rating Agency that such Replacement Depositary will not cause a
          reduction of any rating then in effect for any Class of
          Certificates by such Rating Agency (without regard to any
          downgrading of any rating of the Depositary being replaced and
          without regard to the Policy) and, in either case, the Company
          shall have obtained written confirmation from each Rating Agency
          that such replacement will not cause a reduction or withdrawal of
          any rating then in effect for either Class of Certificates by such
          Rating Agency (without regard to any downgrades of any rating of
          the Depositary being replaced and without regard to the Policy);

               (2)  the Company shall cause the Escrow Agent and the
          Replacement Depositary to enter into a Replacement Deposit

          Provider (in the case of the Replacement Deposit Agreement for the
          Class G Certificates) and each Rating Agency legal opinions and
          other closing documentation substantially similar to those
          delivered by the Depositary being replaced in connection with the
          execution and delivery of the Deposit Agreements being replaced.

     Subject to the foregoing, the Company shall instruct the Pass Through
     Trustee, and the Pass Through Trustee agrees, to execute and deliver to
     the Escrow Agent a duly completed Withdrawal Certificate (as defined in
     the Escrow and Paying Agent Agreement with respect to the Class G
     Certificates (the "Class G Escrow Agreement")) together with a Notice of
     Replacement Withdrawal (as defined in the Class G Escrow Agreement).
     Each of the parties hereto agrees, at the Company's request, to enter
     into any amendments to this Agreement, the Class G Escrow Agreement and
     any other Operative Documents as may be necessary or desirable to give
     effect to the replacement of the Depositary and the Replacement Deposit
     Agreements.  Upon execution and delivery of the Replacement Deposit
     Agreements, the Replacement Depositary shall be deemed to be the
     Depositary with all of the rights and obligations of the Depositary
     hereunder and under the other Operative Documents and the Replacement
     Deposit Agreement shall be deemed to be the Deposit Agreement hereunder
     and under the other Operative Documents, except that the obligations of
     the replaced Depositary under the last sentence of Section 2.2 of the

                                     -14-

49 U.S.C. Section 40102(a)(15) and promptly upon public disclosure of
negotiations in respect of any transaction which would or might adversely
affect such status, notify in writing all parties hereto of all relevant
matters in connection therewith. Upon State Street Bank and Trust Company
giving any such notice, State Street Bank and Trust Company shall, subject to
Section 9.01 of any Indenture then entered into, resign as Trustee in respect
of such Indenture.

          Section 6.  Notices. Unless otherwise specifically provided herein,

delivered personally or, if promptly confirmed by mail, when dispatched by
facsimile or other written telecommunication, addressed to such party hereto
at its address or facsimile number set forth below the signature of such
party at the foot of this Agreement.  Notice shall be given to the Policy
Provider at the address specified in the Policy Provider Agreement.

          Section 7.  Expenses.  (a)  The Company agrees to pay to the
Subordination Agent when due an amount or amounts equal to the fees payable
to the Liquidity Provider under Section 2.03 of each Liquidity Facility and
the related Fee Letter multiplied by a fraction the numerator of which shall
be the then outstanding aggregate amount of the Deposits under the Deposit
Agreements and the denominator of which shall be the sum of (x) the then
outstanding aggregate principal amount of the Series G Equipment Notes and
Series C Equipment Notes issued under all of the Indentures and (y) the then
outstanding aggregate amount of the Deposits under the Deposit Agreements.
The Company agrees to pay the Subordination Agent when due for application in
accordance with the Intercreditor Agreement an amount or amounts equal to the

          (b)  So long as no Equipment Notes have been issued in respect of
any Aircraft, the Company agrees to pay (i) to the Subordination Agent when
due (A) the amount equal to interest on any Downgrade Advance (other than an

any case, as any other party hereto shall reasonably request in connection
with its administration of, or to carry out more effectually the purposes of,
or to better assure and confirm unto it the rights and benefits to be
provided under, this Agreement.

contemplated hereby have been consummated, and except as otherwise provided
for herein, the representations, warranties and agreements herein of the

instrument in writing signed by the party against which the enforcement of
the termination, amendment, supplement, waiver or modification is sought. The

any nature whatsoever against any of the parties hereto, and no person not a
party hereto (other than the Underwriters, the Policy Provider and each of
the beneficiaries of Section 7 hereof) shall have any right, power or
privilege in respect of, or have any benefit or interest arising out of, this
Agreement.

          Section 10.  Indemnity.  The Company hereby agrees to indemnify
each Indemnitee against, and agrees to protect, defend, save and keep
harmless each thereof from any and all liabilities, obligations, losses,
damages, penalties, claims, actions, suits, out-of-pocket costs, expenses,
and disbursements, of whatsoever kind and nature (collectively called
"Expenses") imposed on, incurred by or asserted against any Indemnitee, in
any way relating to or arising out of (A) any of the Financing Agreements or
any lease or sublease of any Aircraft or the enforcement of any of the terms
thereof or any amendment, modification or waiver in respect thereof, (B) the
manufacture, purchase, acceptance or rejection of the Airframe (as defined in
the Participation Agreement) or any Engine (as defined in the Participation
Agreement), (C) the Aircraft (or any portion thereof or any Engine or engine
affixed to the Airframe) whether or not arising out of the finance,
refinance, ownership, delivery, nondelivery, storage, lease, sublease, sub-
sublease, possession, use, non-use, operation, maintenance, registration,
reregistration, condition, modification, alteration, replacement, repair,
substitution, sale, return or other disposition of the Aircraft (or any
portion thereof or any Engine or engine affixed to the Airframe) including,
without limitation, latent or other defects, whether or not discoverable,
strict tort liability and any claim for patent, trademark or copyright

                                     -17-

<PAGE>

infringement, or (D) the offer, sale or delivery of the Equipment Notes (the
indemnity in this clause (D) to extend also to any person who controls an
Indemnitee within the meaning of Section 15 of the Securities Act of 1933, as
amended); provided that the foregoing indemnity as to any Indemnitee shall
not extend to any Expense resulting from or arising out of or which would not
have occurred but for one or more of the following: (A) any representation or
warranty by such Indemnitee (or any of its affiliates) in the Financing
Agreements or in connection therewith being incorrect in any material
respect, or (B) the failure by such Indemnitee (or any of its affiliates) to
perform or observe any agreement, covenant or condition in any of the
Financing Agreements applicable to it (except to the extent such failure was
caused directly by the failure of the Company to perform any obligation under
a Financing Agreement), or (C) the willful misconduct or the gross negligence
of such Indemnitee (or any of its affiliates) other than gross negligence
imputed to such Indemnitee (or any of its affiliates) solely by reason of its
interest in the Aircraft), or (D) any Tax, or (E) the authorization or giving
or withholding of any future amendments, supplements, waivers or consents
with respect to any of the Financing Agreements other than such as have been
consented to, approved, authorized or requested by the Company, or (F)
subject to the next succeeding paragraph, any loss of tax benefits or
increase in tax liability under any tax law whether or not the Company is
required to indemnify therefor pursuant to this Agreement, or (G) any Expense
which is specified to be for the account of an Indemnitee pursuant to any
Financing Agreement without express right of reimbursement under any
Financing Agreement.  The foregoing indemnity shall not extend to any Expense
to the extent that such Expense is not caused by, or does not arise out of,
an act, omission or event which occurs prior to the payment of all payments
required to be paid by the Company under the Financing Agreements.

          The Company further agrees to indemnify the Policy Provider from
and against, and agrees to protect, save and keep harmless the Policy
Provider from any and all Expenses imposed on, incurred by or asserted
against any of them in any way relating to, based on or arising from the
enforcement by the Policy Provider of its rights as a subrogee under the
Class G Escrow and Agreement; provided, that the foregoing indemnity shall
not extend to the Policy Provider with respect to any loss, claim or expense
to the extent such loss, claim or expense is attributable to the Policy
Provider's gross negligence or willful misconduct and provided, further, that
the Policy Provider shall have no claim against any "Collateral" or "Trust
Indenture Estate" (as such terms are defined in the Financing Agreements) for
any payments under this Section 10.

          The Company further agrees that any payment or indemnity pursuant
to this Section 10 in respect of any Expenses shall be in an amount which,
after deduction of all Taxes required to be paid by such recipient with
respect to such payment or indemnity under the laws of any Federal, state or
local government or taxing authority in the United States, or under the laws

                                     -18-

<PAGE>

of any taxing authority or governmental subdivision of a foreign country, or
any territory or possession of the United States or any international
authority, shall be equal to the excess, if any, of (A) the amount of such
Expense over (B) the net reduction in Taxes required to be paid by such
recipient resulting from the accrual or payment of such Expense.

          If, by reason of any Expense payment made to or for the account of
an Indemnitee by the Company pursuant to this Section 10, such Indemnitee
subsequently realizes a tax deduction or credit (including foreign tax credit
and any reduction in Taxes) not previously taken into account in computing
such payment, such Indemnitee shall promptly pay to the Company, but only if
the Company shall have made all payments then due and owing to such
Indemnitee under the Financing Agreements, an amount equal to the sum of (I)
the actual reduction in Taxes realized by such Indemnitee which is
attributable to such deduction or credit, and (II) the actual reduction in
Taxes realized by such Indemnitee as a result of any payment made by such
Indemnitee pursuant to this sentence.

          If a claim is made against an Indemnitee involving one or more
Expenses and such Indemnitee has notice thereof, such Indemnitee shall
promptly, upon receiving such notice, give notice of such claim to the
Company; provided that the failure to provide such notice shall not release
the Company from any of its obligations to indemnify hereunder, and no
payment by the Company to an Indemnitee pursuant to this Section 10 shall be
deemed to constitute a waiver or release of any right or remedy which the
Company may have against such Indemnitee for any actual damages as a result
of the failure by such Indemnitee to give the Company such notice.  The
Company shall be entitled, at its sole cost and expense, acting through
counsel acceptable to the respective Indemnitee, (A) so long as the Company
has agreed in a writing acceptable to such Indemnitee that the Company is
liable to such Indemnitee for such Expense hereunder (unless such Expense is
covered by the proviso to the first paragraph of this Section 10), in any
judicial or administrative proceeding that involves solely a claim for one or
more Expenses, to assume responsibility for and control thereof, (B) so long
as the Company has agreed in a writing acceptable to such Indemnitee that the
Company is liable to such Indemnitee for such Expense hereunder (unless such
Expense is covered by the proviso to the first paragraph of this Section 10),
in any judicial or administrative proceeding involving a claim for one or
more Expenses and other claims related or unrelated to the transactions
contemplated by the Financing Agreements, to assume responsibility for and
control of such claim for Expenses to the extent that the same may be and is
severed from such other claims (and such Indemnitee shall use its best
efforts to obtain such severance), and (C) in any other case, to be consulted
by such Indemnitee with respect to judicial proceedings subject to the
control of such Indemnitee.  Notwithstanding any of the foregoing to the
contrary, the Company shall not be entitled to assume responsibility for and
control of any such judicial or administrative proceedings (M) while an event

                                     -19-

of default shall have occurred and be continuing under any of the Financing
Agreements or (N) if such proceeding could be in the good faith opinion of
such Indemnitee entail any material risk of criminal liability or present a
conflict of interest making separate representation necessary. The affected
Indemnitee may participate at its own expense and with its own counsel in any
judicial proceeding controlled by the Company pursuant to the preceding
provisions.

          The affected Indemnitee shall supply the Company with such
information reasonably requested by the Company as is necessary or advisable
for the Company to control or participate in any proceeding to the extent
permitted by this Section 10.  Such Indemnitee shall not enter into a
settlement or other compromise with respect to any Expense without the prior
written consent of the Company, which consent shall not be unreasonably
withheld or delayed, unless such Indemnitee waives its right to be
indemnified with respect to such Expense under this Section 10.

          The Company shall supply the affected Indemnitee with such
information reasonably requested by such Indemnitee as is necessary or
advisable for such Indemnitee to control or participate in any proceeding to
the extent permitted by this Section 10.

          When the Company or the insurers under a policy of insurance
maintained by the Company undertakes the defense of an Indemnitee with
respect to an Expense, no additional legal fees or expenses of such
Indemnitee in connection with the defense of such Indemnitee shall be
indemnified hereunder unless such fees or expenses were incurred at the
written request of the Company or such insurers, provided that no such
defense shall be compromised or settled on a basis that admits any gross
negligence or willful misconduct on the part of such Indemnitee without such
Indemnitee's prior consent.

          In the event that the Company shall have paid an amount to an
Indemnitee pursuant to this Section 10, and such Indemnitee subsequently
shall be reimbursed in respect of such indemnified amount from any other
Person, such Indemnitee shall promptly pay to the Company an amount equal to
the amount of such reimbursement (but in no event more than such payment from
the Company) plus any net tax benefit (or minus any net tax detriment)
realized by such Indemnitee as a result of any reimbursement received and
payment made by such Indemnitee pursuant to this sentence, provided that (i)
no event of default has occurred and is continuing under any of the Financing
Agreements and (ii) such Indemnitee shall have no obligation to reimburse the
Company if the Company has not paid such Indemnitee all amounts required
pursuant to this Section 10 and any other amounts then due to such Indemnitee
from the Company under any of the Financing Agreements.

          The Company's obligations under the indemnities provided for in
this Agreement shall be those of a primary obligor, whether or not the Person
indemnified shall also be indemnified with respect to the same matter under
the terms of any other document or instrument, and the Person seeking
indemnification from the Company pursuant to this Section 10 may proceed
directly against the Company without first seeking to enforce any other right
of indemnification.

          Section 11.  Termination.  This Agreement shall terminate on the
Delivery Period Termination Date or, if earlier, the date on which Equipment
Notes issued with respect to all of the Aircraft have been purchased by the
Pass Through Trustees in accordance with this Agreement; provided, that, the
provisions of Sections 7, 8, 9 and the second paragraph of Section 10 hereof
shall survive any termination of this Agreement.

          Section 12.  Third Party Beneficiary.  The Policy Provider shall be
an express third party beneficiary with respect to enforcement of Section
5(a)(vi) and the second paragraph of Section 10 hereof.

          Section 13.  Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                           MANDATORY DOCUMENT TERMS

          The terms "Trust Indenture Form," "Lease Form" and "Participation
Agreement Form" shall have the respective meanings specified in Schedule VI
to the Note Purchase Agreement.

          1.   May not modify in any material adverse respect as regards the
interests of the Note Holders, the Subordination Agent, the Liquidity
Provider, the Policy Provider or the Indenture Trustee, the Granting Clause
of the Trust Indenture Form so as to deprive the Note Holders of a first
priority security interest in and mortgage lien on the Aircraft and, in the
case of a Leased Aircraft Indenture, the Lease or to eliminate any of the
obligations intended to be secured thereby or otherwise modify in any
material adverse respect as regards the interests of the Note Holders, the
Subordination Agent, the Liquidity Provider, the Policy Provider or the
Indenture Trustee the provisions of Article II or III or Sections 4.02, 4.03,
4.04, 5.02, 5.06, 9.01 or the first sentence of Section 10.11 of the Leased
Aircraft Indenture Form for the Leased Aircraft or Article II or III or
Sections 4.01, 4.02, 5.02, 7.06(a), 7.06(b), 10.01, or the first sentence of
Section 11.11 of the Owned Aircraft Indenture Form for the Owned Aircraft.

          2.   May not modify in any material adverse respect as regards the
interests of the Note Holders, the Subordination Agent, the Liquidity
Provider, the Policy Provider or the Indenture Trustee the provisions of
Section 3(d)(v), Section 3(f), Section 7(a)(I)(i), clause (6) of the final
paragraph of Section 10(a), Section 16, Section 18, the first and third
sentences of Section 20 or the penultimate sentence of Section 24 of the

the Indenture Trustee of rights expressly granted to the "Indenture Trustee"
therein.

          3.   May not modify in any material adverse respect as regards the
interests of the Note Holders, the Subordination Agent, the Liquidity
Provider or the Indenture Trustee the provisions of Section 4(a)(ix)(1),
4(a)(ix)(2), 4(a)(ix)(3), 4(a)(xxiii) to the extent such section requires
special counsel for the Lessee to deliver an opinion relating to Section 1110
of the Bankruptcy Code, Sections 8(q), 8(cc), 11(b), 12 or the penultimate
sentence of Section 15(c), 15(e) or the provisions of Sections 4(a)(xi),
4(a)(xii), 4(a)(xiii), 4(a)(xiv), 4(a)(xv) and 4(a)(xvi) of the Participation
Agreement Form so as to eliminate the requirement to deliver to the Loan
Participant or the Indenture Trustee, as the case may be, the legal opinions
to be provided to such Persons thereunder (recognizing that the lawyers
rendering such opinions may be changed) or the provisions of Section
8(f)(ii)(C) or otherwise modify the terms of the Participation Agreement Form

                                      -1-

to deprive the Subordination Agent, the Liquidity Provider or the Indenture
Trustee of any indemnity or right of reimbursement in its favor for Expenses
or Taxes.

          4.   May not modify, in any material adverse respect as regards the
interests of the Note Holders, the Subordination Agent, the Liquidity
Provider or the Indenture Trustee, the definition of "Make-Whole Amount" in
the Leased Aircraft Indenture Form (with respect to Equipment Notes relating
to Leased Aircraft) or in Annex A to the Owned Aircraft Indenture Form (with
respect to Equipment Notes relating to Owned Aircraft).

          Notwithstanding the foregoing, any such Mandatory Document Term may
be modified to correct or supplement any such provision which may be
defective or to cure any ambiguity or correct any mistake, provided, however,
that any such action shall not materially adversely affect the interests of
the Note Holders, the Subordination Agent, the Liquidity Provider, the Policy
Provider, the Indenture Trustee or the Certificate Holders.
