     NOW, THEREFORE, in consideration of the obligations contained herein, and
for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the parties hereto hereby agree as follows:

                                    ARTICLE 1
                              FORMATION OF DEPOSITS

     1.1 ACCEPTANCE OF DEPOSITARY. The Depositary hereby agrees to act as
depositary bank as provided herein and in connection therewith to accept all
amounts to be delivered to or held by the Depositary pursuant to the terms of
this Agreement. The Depositary further agrees to hold, maintain and safeguard
the Deposits and the Accounts (as defined below) during the term of this
Agreement in accordance with the provisions of this Agreement. The Escrow Agent
shall not have any right to withdraw, assign or otherwise transfer moneys held
in the Accounts except as permitted by this Agreement.

     1.2 ESTABLISHMENT OF ACCOUNTS. The Escrow Agent hereby instructs the
Depositary, and the Depositary agrees, to establish the separate deposit
accounts listed on Schedule I hereto and to establish such additional separate
deposit accounts as may be required in connection with the deposits contemplated
by Section 2.4 hereof (each, an "ACCOUNT" and collectively, the "ACCOUNTS"),
each in the name of the Escrow Agent and all on the terms and conditions set
forth in this Agreement.

                                    ARTICLE 2
                             MAINTENANCE OF DEPOSITS

     2.1 DEPOSITS. The Escrow Agent shall direct the Underwriters to deposit
with the Depositary on the date of this Agreement (the "DEPOSIT DATE") in
Federal (same day) funds by wire transfer to: Federal Reserve Bank, New York,
ABN NY ABA #02009580, Account: Chicago Treasury, Reference: Northwest Airlines
2001-1 EETC, and the Depositary shall accept from the Underwriters, on behalf of
the Escrow Agent, the sum of US $201,112,000.00. Upon acceptance of such sum,
the Depositary shall (i) establish each of the deposits specified in Schedule I
hereto maturing on the respective dates (each such date, as it may be extended
from time to time in accordance with, and subject to the requirements of, the
Indemnity Agreement (as defined herein) through the Delivery Period Termination
Date, a "MATURITY DATE") set forth therein (including any deposit made pursuant
to Section 2.4 hereof, individually, a "DEPOSIT" and, collectively, the
"DEPOSITS") and (ii) credit each Deposit to the related Account as set forth
therein. No amount shall be deposited in any Account other than the related
Deposit.

                                       2
<PAGE>

     2.2 INTEREST. Each Deposit shall bear interest from and including the date
of deposit to but excluding the earlier of (x) date of withdrawal and (y) such
Deposit's Maturity Date at the rate of 7.626% per annum (computed on the basis
of a year of twelve 30-day months) payable to the Paying Agent on behalf of the
Escrow Agent semiannually in arrears on each April 1 and October 1, commencing
on October 1, 2001 (each, an "INTEREST PAYMENT DATE"), and (except in the case
of a Final Withdrawal (as defined below) made pursuant to a Notice of
Replacement Withdrawal (as defined below) on a day which is not an Interest
Payment Date) on the date of the Final Withdrawal (as defined below) and on the
date of any Series D Non-Issuance Withdrawal (as defined below) all in
accordance with the terms of this Agreement (whether or not any such Deposit is
withdrawn on an Interest Payment Date). Interest accrued on (i) any Deposit that
is withdrawn pursuant to a Notice of Purchase Withdrawal (as defined below) and
(ii) that portion of a Deposit which is withdrawn pursuant to a Notice of
Non-Issuance Withdrawal and redeposited pursuant to Section 2.4 hereof shall be
paid on the next Interest Payment Date, notwithstanding, in the case of retained
interest due to a Notice of Purchase Withdrawal only, any intervening Final
Withdrawal (it being understood that retained interest due to a Notice of
Non-Issuance Withdrawal would be paid on such intervening Final Withdrawal Date)
(such remaining interest being hereinafter referred to as a "CARRYOVER
DEPOSIT"). In addition, interest accrued on any Deposit that is withdrawn
pursuant to a Notice of Replacement Withdrawal but not paid on the date of the
Final Withdrawal shall be paid on the next Interest Payment Date.

     2.3 WITHDRAWALS. On and after the date seven (7) days after the
establishment of each Deposit, the Escrow Agent may, by providing at least one
(1) Business Day prior notice of withdrawal to the Depositary in the form of
Exhibit A hereto (a "NOTICE OF PURCHASE WITHDRAWAL"), withdraw not less than the
entire balance of such Deposit. At any time prior to the actual withdrawal of
any such Deposit, the Escrow Agent or the Pass Through Trustee may, by notice to
the Depositary, cancel such withdrawal (including on the scheduled date
therefor), and thereafter such Deposit shall continue to be maintained by the
Depositary in accordance with the original terms thereof. Following such
withdrawal the balance in the related Account shall be zero and the Depositary
shall close such Account. As used herein, "BUSINESS DAY" means any day, other
than a Saturday, Sunday or other day on which commercial banks are authorized or
required by law to close in New York, New York, Minneapolis, Minnesota, Boston,
Massachusetts, Hartford, Connecticut, Salt Lake City, Utah or Chicago, Illinois.
The Depositary reserves the right, upon at least fourteen (14) days prior notice
to Northwest, the Escrow Agent and the Pass Through Trustee, to require seven
(7) days notice for any withdrawal.

     (a) (i) The Escrow Agent may, by providing at least fifteen (15) days prior
notice of withdrawal to the Depositary in the form of Exhibit B hereto (a
"NOTICE OF FINAL WITHDRAWAL"), withdraw the entire amount of all of the
remaining Deposits together with the payment by the Depositary of all accrued
and unpaid interest on such Deposits to but excluding the specified date of
withdrawal (a "FINAL WITHDRAWAL"), on such date as shall be specified in such
Notice of Final Withdrawal. If neither a Notice of Final Withdrawal nor a Notice
of Replacement Withdrawal has been given to the Depositary on or before March
31, 2003, and there are unwithdrawn Deposits on such date, the Depositary shall
pay the amount of the Final Withdrawal to the Paying Agent on such date as
designated by Northwest pursuant to the Indemnity Agreement dated as of June 1,
2001 between Northwest and the Depositary (the "INDEMNITY AGREEMENT") but in any
event not later than April 15, 2003.

          (ii) The Escrow Agent may, by providing at least fifteen (15) days
     prior notice of withdrawal to the Depositary in the form of Exhibit C
     hereto (a "NOTICE OF REPLACEMENT WITHDRAWAL"), request withdrawal of the
     entire amount of all Deposits then held by the Depositary together with, if
     specified in such Notice of Replacement Withdrawal, the payment by the
     Depositary of all accrued and unpaid interest on such Deposits to but
     excluding the specified date of withdrawal (a "REPLACEMENT WITHDRAWAL") on
     such date as shall be specified in such Notice of Replacement Withdrawal.

          (iii) On or after the date seven (7) days after the establishment of
     each Deposit, the Escrow Agent may, by providing at least one (1) Business
     Day prior notice of withdrawal to the Depositary in the Form of Exhibit D
     hereto (a "NOTICE OF SERIES D NON-ISSUANCE WITHDRAWAL") request the entire
     amount of each Deposit specified in such notice together with payment by
     the Depositary of the accrued and unpaid interest on that portion of such
     Deposit not to be redeposited on such day pursuant to Section 2.4 hereof
     (as specified in the Notice of Series D Non-Issuance Withdrawal) to but
     excluding the specified date of withdrawal ("SERIES D NON-ISSUANCE
     WITHDRAWAL"), on such date as shall be specified in such Notice of Series D
     Non-Issuance Withdrawal. At any time prior to the actual withdrawal of any
     such Deposit, the Escrow Agent or the Pass Through Trustee may, by notice
     to the Depositary, cancel such withdrawal (including on the scheduled date
     therefor), and thereafter such Deposit shall continue to be maintained by
     the Depositary in accordance with the original terms thereof. Following
     such withdrawal the balance in the related Account shall be zero and the
     Depositary shall close such Account.

     (b) If the Depositary receives a duly completed Notice of Purchase
Withdrawal, Notice of Final Withdrawal, Notice of Replacement Withdrawal or
Notice of Series D Non-Issuance Withdrawal complying with the provisions of this
Agreement, it shall make the payments specified therein in accordance with the
provisions of this Agreement.

     2.4 OTHER ACCOUNTS. On the date of withdrawal of any Deposit pursuant to a
Notice of Purchase Withdrawal, the Escrow Agent, or the Pass Through Trustee on
behalf of the Escrow Agent, shall be entitled to re-deposit with the Depositary
any portion thereof and the Depositary shall accept the same for deposit
hereunder. Any sums so received for deposit shall be established as a new
Deposit and credited to a new Account, all as more fully provided in Section 2.1
hereof, and thereafter the provisions of this Agreement shall apply thereto as
fully and with the same force and effect as if such Deposit had been established
on the Deposit Date except that (i) such Deposit may not be withdrawn prior to
the date seven days after the establishment thereof and (ii) such Deposit shall
mature on such date as designated by Northwest pursuant to the Indemnity
Agreement and bear interest as provided in Section 2.2 hereof. The Depositary
shall promptly give notice to the Escrow Agent of receipt of each such
re-deposit and the account number assigned thereto.

                                   TERMINATION

     3.1 This Agreement shall terminate on the fifth (5th) Business Day after
the later of the date on which (i) all of the Deposits shall have been withdrawn
and paid as provided herein without any re-deposit and (ii) all accrued and
unpaid interest on the Deposits shall have been paid as provided herein, but in
no event prior to the date on which the Depositary shall have performed in full
its obligations hereunder.

     3.2 For the avoidance of doubt, the obligations of the Depositary under the
last two (2) sentences of Section 2.2 hereof shall remain in full force and
effect notwithstanding the execution and delivery of a replacement Deposit
Agreement in accordance with the Note Purchase Agreement.

                                   ARTICLE 4
                                    PAYMENTS

     All payments (including, without limitation, those payments made in respect
of Taxes (as defined and provided for below)) made by the Depositary hereunder
shall be paid in United States Dollars and immediately available funds by wire
transfer (i) in the case of accrued interest on the Deposits payable under
Section 2.2 or 2.3(a)(iii) hereof or any Final Withdrawal, directly to the
Paying Agent on behalf of the Escrow Agent at State Street Bank and Trust
Company, Two International Place, Boston, Massachusetts 02110, Attention:
Corporate Trust Department, Reference: Northwest Airlines 2001-1 EETC, or to
such other account as the Paying Agent may direct from time to time in writing
to the Depositary and the Escrow Agent and (ii) in the case of any withdrawal of
one or more Deposits pursuant to a Notice of Purchase Withdrawal or all the then
remaining Deposits pursuant to a Notice of Replacement Withdrawal, directly to
or as directed by the Pass Through Trustee as specified and in the manner
provided in such Notice of Purchase Withdrawal or Notice of Replacement
Withdrawal. The Depositary hereby waives any and all rights of set-off,
combination of accounts, right of retention or similar right (whether arising
under applicable law, contract or otherwise) it may have against the Deposits
howsoever arising. Except as provided below, all payments on or in respect of
each Deposit shall be made free and clear of and without reduction for or on
account of any and all taxes, levies or other impositions or charges
(collectively, "TAXES"). However, if the Depositary or the Paying Agent
(pursuant to Section 2.4 of the Escrow and Paying Agent Agreement) shall be
required by law to deduct or withhold any Taxes from or in respect of any sum
payable hereunder, the Depositary shall: (i) make such deductions or
withholding; (ii) pay the full amount deducted or withheld (including in respect
of such additional amounts) to the competent taxation authority; and (iii) if
the Taxes required to be deducted or withheld are imposed by the Netherlands or
any political subdivision thereof, pay such additional amounts as may be
necessary in order that the actual amount received by the designated recipient
of such sum under this Agreement or the Escrow and Paying Agent Agreement after
such deduction or withholding equals the sum it would have received had no such
deduction or withholding been required. If the date on which any payment due on
any Deposit would otherwise fall on a day which is not a Business Day, such
payment shall be made on the next succeeding Business Day with the same force
and effect as if made on such scheduled date, and no additional interest shall
accrue in respect of such extension.
