the Investors pursuant to the Escrow Agreement, subject to withdrawal upon

be deposited by the Escrow Agent with the Depositary pursuant to this Agreement,
which provides for the Depositary to pay interest for distribution to the

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

                  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 Deposit and the Account (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 Account except as permitted by this Agreement.

                  SECTION 1.2 Establishment of Account. The Escrow Agent hereby
instructs the Depositary, and the Depositary agrees, to establish the deposit
account listed on Schedule I hereto (the "Account"), in the name of the Escrow
Agent and on the terms and conditions set forth in this Agreement.

                  SECTION 2.1 Deposit. The Escrow Agent shall direct the
Placement Agents to deposit with the Depositary on the date of this Agreement
(the "Deposit Date") in Federal (same day) funds by wire transfer to:
Westdeutsche Landesbank Girozentrale, New York Branch, Reference: Atlas 2000-1B,
and the Depositary shall accept from the Placement Agents, on behalf of the
Escrow Agent, the sum of US$44,741,000. Upon acceptance of such sum, the
Depositary shall (i) establish the deposit specified in Schedule I hereto
maturing on the date set forth therein (the "Deposit") and (ii) credit the
Deposit to the Account as set forth therein. No amount shall be deposited in the
Account other than the related Deposit.

                  SECTION 2.2 Interest. The Depositary shall pay interest on the
balance of the Deposit from and including the date of deposit to but excluding
the date of withdrawal at the rate of 9.057% 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 semi-annually in arrears on each January 2 and July 2, commencing
on July 2, 2000 (each, an "Interest Payment Date"), and on the date of each
Prepayment Withdrawal and the Final Withdrawal (as defined below), all in
accordance with the terms of this Agreement (whether or not any portion of the
Deposit is withdrawn on an Interest Payment Date); provided, however, that in
the event that no Registration Event (as defined in the Registration Rights
Agreement) occurs on or prior to the 210th day after the date of the issuance of
the Certificates (the "Registration Date"), the interest rate per annum paid by
the Depositary


<PAGE>   4


on each Deposit shall be increased by 0.50%, effective from and including the
210th day after the date of issuance of the Certificates, to but excluding the
date on which a Registration Event occurs; and provided, further, that in the
event that a Shelf Registration Statement (as defined in the Registration Rights
Agreement) ceases to be effective for more than 60 days, whether or not
consecutive, during any 12-month period at any time before the earlier of (a)
the second anniversary of the effective date of the Shelf Registration Statement
or (b) the sale pursuant to the Shelf Registration Statement of all the
Certificates covered thereby, the interest rate per annum paid by the Depositary
on each Deposit shall be increased by 0.50% per annum from the 61st day of the
applicable 12-month period such Shelf Registration Statement ceases to be
effective until such time as the Shelf Registration Statement again becomes
effective. Interest accrued on any portion of the Deposit when 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.

                  SECTION 2.3 Withdrawals. (a) On and after the date seven days
after the establishment of the Deposit, the Escrow Agent may, by providing at
least one Business Day's prior notice of withdrawal to the Depositary in the
form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw all or a
portion of the Deposit, except that at any time prior to the actual withdrawal
of the 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 the Deposit shall continue to be maintained by the
Depositary in accordance with the original terms thereof. Following such
withdrawal the balance in the Account shall be reduced by the amount of the
withdrawal. 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, Denver, Colorado, Salt Lake City, Utah or
Wilmington, Delaware. If a Notice of Purchase Withdrawal is related to a single
aircraft, the amount of withdrawal specified therein shall not exceed the
maximum principal amount of the Equipment Notes for such aircraft, as specified
in the Offering Memorandum (as defined in the Note Purchase Agreement).

                  (b) The Escrow Agent may, by providing at least 15 days' prior
notice of withdrawal to the Depositary in the form of Exhibit B hereto (a
"Notice of Prepayment Withdrawal"), withdraw all or a portion of the Deposit
together with all accrued and unpaid interest thereon to but excluding the
specified date of withdrawal (a "Prepayment Withdrawal"), on such date as shall
be specified in such Notice of Prepayment Withdrawal. Following such withdrawal
the balance in the Account shall be reduced by the amount of the withdrawal.
Upon any Prepayment Withdrawal, the Depositary shall pay to the Paying Agent the
amount requested in the related Notice of Prepayment Withdrawal, provided that
after giving pro forma effect to any Prepayment Withdrawal, the remaining amount
of the Deposit shall not be less than the maximum principal amount of the
Equipment Notes issuable in respect of any aircraft scheduled to be delivered
after the date of such Prepayment Withdrawal, as specified in the Offering
Memorandum.

                  (c) The Escrow Agent may, by providing at least 15 days' prior
notice of withdrawal to the Depositary in the form of Exhibit C hereto (a
"Notice of Final Withdrawal"),


<PAGE>   5


withdraw the entire amount of the Deposit together with the all accrued and
unpaid interest on the Deposit to but excluding the specified date of withdrawal
(a "Final Withdrawal"), on such date as shall be specified in such Notice of
Final Withdrawal. Following such withdrawal the balance in the Account shall be
zero and the Depositary shall close such Account. If a Notice of Final
Withdrawal has not been given to the Depositary on or before December 31, 2000
(provided that if a labor strike or work stoppage occurs at The Boeing Company
prior to such date, such date shall be extended by adding thereto the number of
days that each such labor strike or work stoppage continues in effect) and there
are unwithdrawn amounts in the Account on such date, the Depositary shall pay
the amount of the Final Withdrawal to the Paying Agent on January 16, 2001 (or
if the December 31, 2000 date has been extended as set forth in this sentence,
the fifteenth day after the Delivery Period Termination Date).

                  (d) If the Depositary receives a duly completed Notice of
Purchase Withdrawal, Notice of Prepayment 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.
No notice of withdrawal shall be given within seven days after the date of the
immediately preceding notice of withdrawal.

                  SECTION 2.4 Re-Deposit. On the date of withdrawal of any
portion of the 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 deemed not to have been withdrawn for
all purposes hereof.

                  SECTION 3.1 Termination. This Agreement shall terminate on the
later of the date on which (i) all of the Deposit shall have been withdrawn and
paid as provided herein without any re-deposit and (ii) all accrued and unpaid
interest on the Deposit 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.

                  SECTION 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 Deposit payable under Section 2.2 hereof, any Prepayment
Withdrawal or any Final Withdrawal, directly to the Paying Agent at Wilmington
Trust Company, Wilmington, Delaware, ABA # 03-11-000-92, Account No. 50849-0,
Attention: Robert Hines, Reference: Atlas Air 2000-1B, 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 all or a portion
of the Deposit pursuant to a Notice of Purchase Withdrawal, directly to or 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 Deposit howsoever arising. All payments on or in respect of the
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


<PAGE>   6


(collectively, "Taxes"). However, if the Depositary or the Paying Agent
(pursuant to Section 2.04 of the Escrow 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 Federal Republic of Germany 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 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 the 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.

                  SECTION 5. Representation and Warranties. The Depositary
hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through
Trustee and the Paying Agent that:

                  (a) it is duly organized and validly existing as a German

         of it and do not require any stockholder approval, or approval or
         consent of any trustee or holder of any indebtedness or obligations of
         it, and such document has been duly executed and delivered by it and
         constitutes its legal, valid and binding obligations enforceable
         against it in accordance with the terms hereof;

                  (d) no authorization, consent or approval of or other action
         by, and no notice to or filing with, any United States federal or state
         governmental authority or regulatory body is required for the
         execution, delivery or performance by it of this Agreement;

                  (e) neither the execution, delivery or performance by it of
         this Agreement, nor compliance with the terms and provisions hereof,

         or violation of any of the terms, conditions or provisions of, or will
         require any consent or approval under, any law, governmental rule or

         constitute a default thereunder or results or will result in the
         imposition of any lien upon any of its properties;

                  (f) there are no pending or, to its knowledge, threatened
         actions, suits, investigations or proceedings (whether or not
         purportedly on behalf of it) against or affecting it or any of its
         property before or by any court or administrative agency which, if
         adversely determined, (i) would adversely affect the ability of it to
         perform its obligations under this Agreement or (ii) would call into
         question or challenge the validity of this Agreement or the
         enforceability hereof in accordance with the terms hereof, nor is the

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 the Escrow
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.

                  SECTION 7. Amendment, Etc. This Agreement may not be amended,
waived or otherwise modified except by an instrument in writing signed by the
