                                                   [Deposit Agreement (Class C)]

      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

      Section 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.

      Section 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

      Section 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
1999-3 EETC, and the Depositary shall accept from the Underwriters, on behalf of
the Escrow Agent, the sum of US$31,947,000.00. Upon acceptance of such sum, the
Depositary shall (i) establish each of the deposits specified in


                                       2
<PAGE>

                                                   [Deposit Agreement (Class C)]

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.

      Section 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 9.152% 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 April 1, 2000 (each, an "Interest Payment Date"), and on the
date of the Final 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 any Deposit that is withdrawn
pursuant to a Notice of Purchase Withdrawal (as defined below) shall be paid on
the next Interest Payment Date, notwithstanding any intervening Final Withdrawal
(such remaining interest being hereinafter referred to as a "Carryover
Deposit").

      Section 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 Days 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) 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 a Notice of Final Withdrawal has not been given
to the Depositary on or before July 31, 2000, 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


                                       3
<PAGE>

                                                   [Deposit Agreement (Class C)]

pursuant to the Indemnity Agreement dated as of December 9, 1999 between
Northwest and the Depositary (the "Indemnity Agreement") but in any event not
later than August 15, 2000.

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

      Section 2.4 Other Accounts. On the date of withdrawal of any Deposit, 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.

                                    ARTICLE 3
                                   TERMINATION

      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.

                                    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 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 1999-3 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, directly to or


                                       4
<PAGE>

                                                   [Deposit Agreement (Class C)]

as directed by the Pass Through Trustee as specified and in the manner provided
in such Notice of Purchase 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.

                                    ARTICLE 5
                         REPRESENTATIONS AND WARRANTIES

authority or regulatory body is required for the execution, delivery or
performance by it of this Agreement;

call into question or challenge the validity of this Agreement or the
enforceability hereof in accordance with the terms hereof, nor is the Depositary
in default with respect to any order of any court, governmental authority,
arbitration board or administrative agency so as to adversely affect its ability
to perform its obligations under this Agreement; and

            (g) the Depositary shall act through its Chicago branch office in
connection with the transactions contemplated by this Agreement.

                                    ARTICLE 6
                                    TRANSFER

      Neither party hereto shall be entitled to assign or otherwise transfer
this Agreement (or any interest herein) other than (in the case of the Escrow
Agent) to a successor escrow agent under Section 1.7 of the Escrow and Paying
Agent Agreement, and any purported assignment in violation thereof shall be
void. This Agreement shall be binding upon the parties hereto and their
respective successors and (in the case of the Escrow Agent) permitted assigns.
