                       AMOUNT AND TERMS OF THE COMMITMENT

                  Section 2.01. The Advances. The Liquidity Provider hereby
irrevocably agrees, on the terms and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the period
from the Effective Date until 12:00 Noon (New York City time) on the Expiry Date
(unless the obligations of the Liquidity Provider shall be earlier terminated in
accordance with the terms of Section 2.04(b)) in an aggregate amount at any time
outstanding not to exceed the Maximum Commitment.

                  Section 2.02. Making the Advances. (a) Interest Advances shall
be made in one or more Borrowings by delivery to the Liquidity Provider of one
or more written and completed Notices of Borrowing in substantially the form of
Annex I attached hereto, signed by a Responsible Officer of the Borrower, in an
amount not exceeding the Maximum Commitment at such time and shall be used
solely for the payment when due of the interest on the Class C Certificates at
the Stated Interest Rate therefor in accordance with Section 3.6(a) of the
Intercreditor Agreement. Each Interest Advance made hereunder shall
automatically reduce the Maximum Commitment and the amount available to be
borrowed hereunder by subsequent Advances by the amount of such Interest Advance
(subject to reinstatement as provided in the next sentence). Upon repayment to
the Liquidity Provider in full of the amount of any Interest Advance made
pursuant to this Section 2.02(a), together with accrued interest thereon (as
provided herein), the Maximum Commitment shall be reinstated by the amount of
such repaid Interest Advance; provided, however, that the Maximum Commitment
shall not be so reinstated at any time if (i) a Liquidity Event of Default shall
have occurred and be continuing and (ii) there is a Performing Note Deficiency.

                  (b) A Non-Extension Advance shall be made in a single
Borrowing if this Agreement is not extended in accordance with section 3.6(d) of
the Intercreditor Agreement (unless a Replacement Liquidity Facility to replace
this Agreement shall have been delivered to the Borrower as contemplated by said
Section 3.6(d) within the time period specified in such Section) by delivery to
the Liquidity Provider of a written and completed Notice of Borrowing in
substantially the form of Annex II attached hereto, signed by a Responsible
Officer of the Borrower, in an amount equal to the Maximum Commitment at such
time, and shall be used to fund the Class C Cash Collateral Account in
accordance with said Section 3.6(d) and Section 3.6(f) of the Intercreditor
Agreement.

                  (c) A Downgrade Advance shall be made in a single Borrowing,
as provided for in Section 3.6(c) of the Intercreditor Agreement, (i) upon a
downgrading of the Guarantor's short-term unsecured debt rating issued by either
Rating Agency below the applicable Threshold Rating or (ii) if the Guarantee
Agreement ceases to be in full force and effect, becomes invalid or
unenforceable or the Guarantor denies its liability thereunder (any such
occurrence, a " Guarantee Event"), unless a Replacement Liquidity Facility to
replace this Agreement shall have been previously delivered to the Borrower in
accordance with said Section 3.6(c), by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of

                                       8
<PAGE>   13

Annex III attached hereto, signed by a Responsible Officer of the Borrower, in
an amount equal to the Maximum Commitment at such time, and shall be used to
fund the Class C Cash Collateral Account in accordance with said Section 3.6(c)
and Section 3.6(f) of the Intercreditor Agreement.

                  (d) A Final Advance shall be made in a single Borrowing upon
the receipt by the Borrower of a Termination Notice from the Liquidity Provider
pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of Annex IV
attached hereto, signed by a Responsible Officer of the Borrower, in an amount
equal to the Maximum Commitment at such time, and shall be used to fund the
Class C Cash Collateral Account (in accordance with Section 3.6(i) of the
Intercreditor Agreement) and Section 3.6(f) of the Intercreditor Agreement.

                  (e) Each Borrowing shall be made on notice in writing(a "
Notice of Borrowing") in substantially the form required by Section 2.02(a),
2.02(b), 2.02(c) or 2.02(d), as the case may be, given by the Borrower to the
Liquidity Provider. If a Notice of Borrowing is delivered by the Borrower in
respect of any Borrowing no later than 1:00 PM (New York City time) on a
Business Day, upon satisfaction of the conditions precedent set forth in Section
4.02 with respect to a requested Borrowing, the Liquidity Provider shall make
available to the Borrower, in accordance with its payment instructions, the
amount of such Borrowing in U.S. dollars and immediately available funds, before
4:00 PM (New York City time) on the day of receipt of such Notice of Borrowing
or on such later Business Day specified in such Notice of Borrowing. If a Notice
of Borrowing is delivered by the Borrower in respect of any Borrowing after 1:00
PM (New York City time) on a Business Day, upon satisfaction of the conditions
precedent set forth in Section 4.02 with respect to a requested Borrowing, the
Liquidity Provider shall make available to the Borrower, in accordance with its
payment instructions, the amount of such Borrowing in U.S. dollars and
immediately available funds, before 4:00 PM (New York City time) on the first
Business Day next following the day of receipt of such Notice of Borrowing or on
such later Business Day specified by the Borrower in such Notice of Borrowing.
Payments of proceeds of a Borrowing shall be made by wire transfer of
immediately available funds to the Borrower in accordance with such wire
transfer instructions as the Borrower shall furnish from time to time to the
Liquidity Provider for such purpose. Each Notice of Borrowing shall be
irrevocable and binding on the Borrower.

                  (f) Upon the making of any Advance requested pursuant to a
Notice of Borrowing, in accordance with the Borrower's payment instructions, the
Liquidity Provider shall be fully discharged of its obligation hereunder with
respect to such Notice of Borrowing, and the Liquidity Provider shall not
thereafter be obligated to make any further Advances hereunder in respect of
such Notice of Borrowing to the Borrower or to any other Person. If the
Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing
before 12:00 Noon (New York City time) on the second Business Day after the date
of payment specified in said Section 2.02(e), the Liquidity Provider shall have
fully discharged its obligations hereunder with respect to such Advance and an
event of default shall not have occurred hereunder. Following the making of any
Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the Class C Cash
Collateral Account, the Liquidity Provider shall have no interest in or rights
to the Class C

                                       9
<PAGE>   14

Cash Collateral Account, such Advance or any other amounts from time to time on
deposit in the Class C Cash Collateral Account; provided that the foregoing
shall not affect or impair the obligations of the Subordination Agent to make
the distributions contemplated by Section 3.6(e) or (f) of the Intercreditor
Agreement. By paying to the Borrower proceeds of Advances requested by the
Borrower in accordance with the provisions of this Agreement, the Liquidity
Provider makes no representation as to, and assumes no responsibility for, the
correctness or sufficiency for any purpose of the amount of the Advances so made
and requested.

                  Section 2.03. Fees. The Borrower agrees to pay to the
Liquidity Provider the fees set forth in the MSCS Fee Letter.

                  Section 2.04. Reduction or Termination of the Maximum
Commitment.

                  (a) Automatic Reduction. Promptly following each date on which
the Required Amount is reduced as a result of a reduction in the Pool Balance of
the Class C Certificates or otherwise, the Maximum Commitment shall
automatically be reduced to an amount equal to such reduced Required Amount (as
calculated by the Borrower). The Borrower shall give notice of any such
automatic reduction of the Maximum Commitment to the Liquidity Provider within
two Business Days thereof. The failure by the Borrower to furnish any such
notice shall not affect such automatic reduction of the Maximum Commitment.

                  (b) Termination. Upon the making of any Provider Advance or
Final Advance hereunder or the occurrence of the Termination Date, the
obligation of the Liquidity Provider to make further Advances hereunder shall
automatically and irrevocably terminate, and the Borrower shall not be entitled
to request any further Borrowing hereunder.

                  Section 2.05. Repayments of Interest Advances or the Final
Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby
agrees, without notice of an Advance or demand for repayment from the Liquidity
Provider (which notice and demand are hereby waived by the Borrower), to pay, or
to cause to be paid, to the Liquidity Provider on each date on which the
Liquidity Provider shall make an Interest Advance or the Final Advance, an
amount equal to (a) the amount of such Advance (any such Advance, until repaid,
is referred to herein as an "Unpaid Advance"), plus (b) interest on the amount
of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if
(i) the Liquidity Provider shall make a Provider Advance at any time after
making one or more Interest Advances which shall not have been repaid in
accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a
Downgraded Facility or Non-Extended Facility at any time when unreimbursed
Interest Advances have reduced the Maximum Commitment to zero, then such
Interest Advances shall cease to constitute Unpaid Advances and shall be deemed
to have been changed into an Applied Downgrade Advance or Applied Non-Extension
Advance for all purposes of this Agreement (including, without limitation, for
the purpose of determining when such Interest Advance is required to be repaid
to the Liquidity Provider in accordance with Section 2.06 and for the purposes
of Section 2.06(b)). The Borrower and the Liquidity Provider agree that the
repayment in full of each Interest Advance and Final Advance on the date such
Advance is made is intended to be a contemporaneous exchange for new value given
to the Borrower by the Liquidity Provider.

                  Section 2.06. Repayments of Provider Advances. (a) Amounts
advanced hereunder in respect of a Provider Advance shall be deposited in the
Class C Cash Collateral Account, invested and withdrawn from the Class C Cash
Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the
Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider,
on each Regular Distribution Date, commencing on the first Regular Distribution
Date after the making of a Provider Advance, interest on the principal amount of
any such Provider Advance as provided in Section 3.07; provided, however, that
amounts in respect of a Provider Advance withdrawn from the Class C Cash
Collateral Account for the purpose of paying interest on the Class C
Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement
(the amount of any such withdrawal being (x) in the case of a Downgrade Advance,
an "Applied Downgrade Advance" and (y) in the case of a Non-Extension Advance,
an "Applied Non-Extension Advance" and, together with an Applied Downgrade
Advance, an "Applied Provider Advance") shall thereafter (subject to Section
2.06(b)) be treated as an Interest Advance under this Agreement for purposes of
determining the Applicable Liquidity Rate for interest payable thereon; provided
further, however, that if, following the making of a Provider Advance, the
Liquidity Provider delivers a Termination Notice to the Borrower pursuant to
Section 6.01 hereof, such Provider Advance shall thereafter be treated as a
Final Advance under this Agreement for purposes of determining the Applicable
Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09
hereof, immediately upon the withdrawal of any amounts from the Class C Cash
Collateral Account on account of a reduction in the Required Amount, the
Borrower shall repay to the Liquidity Provider a portion of the Provider
Advances in a principal amount equal to such reduction, plus interest on the
principal amount prepaid as provided in Section 3.07 hereof.

                  (b) At any time when an Applied Provider Advance (or any
portion thereof) is outstanding, upon the deposit in the Class C Cash Collateral
Account of any amount pursuant to clause "third" of Section 2.4(b) of the
Intercreditor Agreement, clause "third" of Section 3.2 of the Intercreditor
Agreement or clause "fourth" of Section 3.3 of the Intercreditor Agreement (any
such amount being a "Replenishment Amount") for the purpose of replenishing or
increasing the balance thereof up to the Required Amount at such time, (i) the
aggregate outstanding principal amount of all Applied Provider Advances (and of
Provider Advances treated as an Interest Advance for purposes of determining the
Applicable Liquidity Rate for interest payable thereon) shall be automatically
reduced by the amount of such Replenishment Amount and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances shall be
automatically increased by the amount of such Replenishment Amount.

                  (c) Upon the provision of a Replacement Liquidity Facility in
replacement of this Agreement in accordance with Section 3.6(e) of the
Intercreditor Agreement, amounts remaining on deposit in the Class C Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider, but only
to the extent such amounts are necessary to repay in full to the Liquidity
Provider all amounts owing to it hereunder.

Liquidity Provider of any amounts hereunder, the Intercreditor Agreement
provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the
Liquidity Provider in accordance with the terms thereof. Amounts so paid to the
Liquidity Provider shall be applied by the Liquidity Provider to Liquidity
Obligations then due and payable in accordance with the Intercreditor Agreement
or, if not provided for in the Intercreditor Agreement, then in such manner as
the Liquidity Provider shall deem appropriate.

                  Section 2.08. Book Entries. The Liquidity Provider shall
maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of the Borrower resulting from Advances made from time to time
and the amounts of principal and interest payable hereunder and paid from time
to time in respect thereof; provided, however, that the failure by the Liquidity
Provider to maintain such account or accounts shall not affect the obligations
of the Borrower in respect of Advances.

                  Section 2.09. Payments from Available Funds Only. All payments
to be made by the Borrower under this Agreement shall be made only from the
amounts that constitute Scheduled Payments, Special Payments or payments under
Section 8.1 or 9.1, as the case may be, of the Participation Agreements and
Section 6 of the Note Purchase Agreement and only to the extent that the
Borrower shall have sufficient income or proceeds therefrom to enable the
Borrower to make payments in accordance with the terms hereof after giving
effect to the priority of payments provisions set forth in the Intercreditor
Agreement. The Liquidity Provider agrees that it will look solely to such
amounts to the extent available for distribution to it as provided in the
Intercreditor Agreement and this Agreement and that the Borrower, in its
individual capacity, is not personally liable to it for any amounts payable or
liability under this Agreement except as expressly provided in this Agreement,
the Intercreditor Agreement or any Participation Agreement. Amounts on deposit
in the Class C Cash Collateral Account shall be available to the Borrower to
make payments under this Agreement only to the extent and for the purposes
expressly contemplated in Section 3.6(f) of the Intercreditor Agreement.

                  Section 2.10. Extension of the Expiry Date; Non-Extension
Advance. The Expiry Date shall be automatically extended, effective on the 25th
day prior to each Expiry Date (unless such Expiry Date is on or after the date
that is 15 days after the Final Legal Distribution Date for the Class C
Certificates), for a period of 364 days after such Expiry Date (unless the
obligations of the Liquidity Provider are earlier terminated in accordance with
the terms hereof), without the necessity of any act on the part of the Borrower
or the Liquidity Provider, unless the Liquidity Provider shall advise the
Borrower prior to such 25th day that it does not agree to such extension of such
Expiry Date, in which event (and if the Liquidity Provider shall not have been
replaced in accordance with Section 3.6(e) of the Intercreditor Agreement), the
Borrower shall be entitled on and after such 25th day (but prior to such Expiry
Date) to request a Non-Extension Advance in accordance with Section 2.02(b)
hereof and Section 3.6(d) of the Intercreditor Agreement.

                           OBLIGATIONS OF THE BORROWER

                  Section 3.01. Increased Costs. The Borrower shall pay to the
Liquidity Provider from time to time such amounts as may be necessary to
compensate the Liquidity Provider for any increased costs incurred by the
Liquidity Provider which are attributable to its making or maintaining any LIBOR
Advances hereunder or its obligation to make any such Advances hereunder, or any
reduction in any amount receivable by the Liquidity Provider under this
Agreement or the Intercreditor Agreement in respect of any such Advances or such
obligation (such increases in costs and reductions in amounts receivable being
herein called "Additional Costs"), resulting from any change after the date of
this Agreement in U.S. federal, state, municipal, or foreign laws or regulations
("Regulatory Change") which changes the basis of taxation of any amounts payable
to the Liquidity Provider under this Agreement in respect of any such Advances
(other than Excluded Taxes). The Liquidity Provider agrees to use reasonable
efforts (consistent with applicable legal and regulatory restrictions) to change
the jurisdiction of its Lending Office if making such change would avoid the
need for, or reduce the amount of, any amount payable under this Section that
may thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.

                  The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section. Determinations by the Liquidity Provider
for purposes of this Section 3.01 of the effect of any Regulatory Change on its
costs of making or maintaining Advances or on amounts receivable by it in
respect of Advances, and of the additional amounts required to compensate the
Liquidity Provider in respect of any Additional Costs, shall be prima facie
evidence of the amount owed under this Section.

                  Section 3.02. Capital Adequacy. If (1) the adoption, after the
date hereof, of any applicable governmental law, rule or regulation regarding
capital adequacy, (2) any change, after the date hereof, in the interpretation
or administration of any such law, rule or regulation by any central bank or
other governmental authority charged with the interpretation or administration
thereof or (3) compliance by the Liquidity Provider or any corporation
controlling the Liquidity Provider with any applicable guideline or request of
general applicability, issued after the date hereof, by any central bank or
other governmental authority (whether or not having the force of law) that
constitutes a change of the nature described in clause (2), has the effect of
requiring an increase in the amount of capital required to be maintained by the
Liquidity Provider or any corporation controlling the Liquidity Provider, and
such increase is based upon the Liquidity Provider's obligations hereunder and
other similar obligations, the Borrower shall pay to the Liquidity Provider from
time to time such additional amount or amounts as are necessary to compensate
the Liquidity Provider for such portion of such increase as shall be reasonably
allocable to the Liquidity Provider's obligations to the Borrower hereunder. The
Liquidity

                                       13
<PAGE>   18

Provider agrees to use reasonable efforts (consistent with applicable legal and
regulatory restrictions) to change the jurisdiction of its Lending Office if
making such change would avoid the need for, or reduce the amount of, any amount
payable under this Section that may thereafter accrue and would not, in the
reasonable judgment of the Liquidity Provider, be otherwise materially
disadvantageous to the Liquidity Provider.

                  The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section. Determinations by the Liquidity Provider
for purposes of this Section 3.02 of the effect of any increase in the amount of
capital required to be maintained by the Liquidity Provider and of the amount
allocable to the Liquidity Provider's obligations to the Borrower hereunder
shall be prima facie evidence of the amounts owed under this Section.

                  Section 3.03. Payments Free of Deductions. (a) All payments
made by the Borrower under this Agreement shall be made free and clear of, and
without reduction for or on account of, any present or future stamp or other
taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
restrictions or conditions of any nature whatsoever now or hereafter imposed,
levied, collected, withheld or assessed, excluding Excluded Taxes (such
non-excluded taxes being referred to herein, collectively, as "Non-Excluded
Taxes" and, individually, as a "Non-Excluded Tax"). If any Non-Excluded Taxes
are required to be withheld from any amounts payable to the Liquidity Provider
under this Agreement, the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after
payment of all Non-Excluded Taxes) interest or any other such amounts payable
under this Agreement at the rates or in the amounts specified in this Agreement.
The Liquidity Provider agrees to use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need
for, or reduce the amount of, any such additional amounts that may thereafter
accrue and would not, in the reasonable judgment of the Liquidity Provider, be
otherwise disadvantageous to the Liquidity Provider. From time to time upon the
reasonable request of the Borrower, the Liquidity Provider agrees to provide to
the Borrower two original Internal Revenue Service Forms W-8 BEN or W-8 ECI, as
appropriate, or any successor or other form prescribed by the Internal Revenue
Service, certifying that the Liquidity Provider is exempt from or entitled to a
reduced rate of United States withholding tax on payments pursuant to this
Agreement.

                  (b) All payments (including, without limitation, Advances)
made by the Liquidity Provider under this Agreement shall be made free and clear
of, and without reduction for or on account of, any Taxes. If any Taxes are
required to be withheld or deducted from any amounts payable to the Borrower
under this Agreement, the Liquidity Provider shall (i) within the time
prescribed therefor by applicable law pay to the appropriate governmental or
taxing authority the full amount of any such Taxes (and any additional Taxes in
respect of the payment required under clause (ii) hereof) and make such reports
or returns in connection therewith at the time or times and in the manner
prescribed by applicable law, and (ii) pay to the Borrower an additional amount
which (after deduction of all such Taxes) will be sufficient to yield to the

                                       14
<PAGE>   19

Borrower the full amount which would have been received by it had no such
withholding or deduction been made. Within 30 days after the date of each
payment hereunder, the Liquidity Provider shall furnish to the Borrower the
original or a certified copy of (or other documentary evidence of) the payment
of the Taxes applicable to such payment.

                  Section 3.04. Payments. The Borrower shall make or cause to be
made each payment to the Liquidity Provider under this Agreement so as to cause
the same to be received by the Liquidity Provider not later than 1:00 P.M. (New
York City time) on the day when due. The Borrower shall make all such payments
in lawful money of the United States of America, to the Liquidity Provider in
immediately available funds, by wire transfer to Citibank, N.A., New York, NY,
ABA# 021000089, Account Name: Morgan Stanley Capital Services, Inc., Account #
4072-4601, Reference: Atlas Air, Inc., 2000-1B.

                  Section 3.05. Computations. All computations of interest based
on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the LIBOR Rate shall be
made on the basis of a year of 360 days, in each case for the actual number of
days (including the first day but excluding the last day) occurring in the
period for which such interest is payable.

                  Section 3.06. Payment on Non-Business Days. Whenever any
payment to be made hereunder shall be stated to be due on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day and
no additional interest shall be due as a result (and if so made, shall be deemed
to have been made when due). If any payment in respect of interest on an Advance
is so deferred to the next succeeding Business Day, such deferral shall not
delay the commencement of the next Interest Period for such Advance (if such
Advance is a LIBOR Advance) or reduce the number of days for which interest will
be payable on such Advance on the next interest payment date for such Advance.

                  Section 3.07. Interest. (a) Subject to Section 2.09, the
Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of
such Advance (or, in the case of an Applied Provider Advance, from and including
the date on which the amount thereof was withdrawn from the Class C Cash
Collateral Account to pay interest on the Class C Certificates) to but excluding
the date such principal amount shall be paid in full (or, in the case of an
Applied Provider Advance, the date on which the Class C Cash Collateral Account
is fully replenished in respect of such Advance) and (ii) any other amount due
hereunder (whether fees, commissions, expenses or other amounts or, to the
extent permitted by law, installments of interest on Advances or any such other
amount) which is not paid when due (whether at stated maturity, by acceleration
or otherwise) from and including the due date thereof to but excluding the date
such amount is paid in full, in each such case, at a fluctuating interest rate
per annum for each day equal to the Applicable Liquidity Rate (as defined below)
for such Advance or such other amount as in effect for such day, but in no event
at a rate per annum greater than the maximum rate permitted by applicable law;
provided, however, that, if at any time the otherwise applicable interest rate
as set forth in this Section 3.07 shall exceed the maximum rate permitted by
applicable law, then any subsequent reduction in such interest rate will not
reduce the rate of interest payable pursuant to this Section 3.07 below the
maximum rate permitted by applicable law until the total amount of

                                       15
<PAGE>   20

interest accrued equals the amount of interest that would have accrued if such
otherwise applicable interest rate as set forth in this Section 3.07 had at all
times been in effect.

                  (b) Each Advance will be either a Base Rate Advance or a LIBOR
Advance as provided in this Section. Each such Advance will be a Base Rate
Advance for the period from the date of its borrowing to (but excluding) the
third Business Day following the Liquidity Provider's receipt of the Notice of
Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance;
provided that the Borrower (at the direction of the Controlling Party, so long
as the Liquidity Provider is not the Controlling Party) may (x) convert the
Final Advance into a Base Rate Advance on the last day of an Interest Period for
such Advance by giving the Liquidity Provider no less than four Business Days'
prior written notice of such election or (y) elect to maintain the Final Advance
as a Base Rate Advance by not requesting a conversion of the Final Advance to a
LIBOR Advance under Clause (5) of the applicable Notice of Borrowing (or, if
such Final Advance is deemed to have been made without delivery of a Notice of
Borrowing pursuant to Section 2.06, by requesting, prior to 11:00 AM on the
first Business Day immediately following the Borrower's receipt of the
applicable Termination Notice, such that such Final Advance not be converted
from a Base Rate Advance to a LIBOR Advance).

                  (c) Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest
Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on
the last day of such Interest Period and, in the event of the payment of
principal of such LIBOR Advance on a day other than such last day, on the date
of such payment (to the extent of interest accrued on the amount of principal
repaid).

                  (d) Each Base Rate Advance shall bear interest at a rate per
annum equal to the Base Rate plus the Applicable Margin for such Base Rate
Advance, payable in arrears on each Regular Distribution Date and, in the event
of the payment of principal of such Base Rate Advance on a day other than a
Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid).

                  (e) Each Unapplied Provider Advance shall bear interest as
provided in Section 3.07(b) hereof plus an amount equal to the amount by which
(i) the Investment Earnings plus 0.50% per annum on the outstanding amount from
time to time of such Advance for the period for which interest is calculated
pursuant to clause (ii) hereof exceeds (ii) the amount of interest on such
Unapplied Provider Advance under Section 3.07(b).

                  (f) Each amount not paid by the Borrower when due hereunder
(whether fees, commissions, expenses or other amounts or, to the extent
permitted by applicable law, installments of interest on Advances but excluding
Advances) shall bear interest at a rate per annum equal to the Base Rate plus
2.00% until paid.

                  (g) Each change in the Base Rate shall become effective
immediately. The rates of interest specified in this Section 3.07 with respect
to any Advance or other amount shall be referred to as the "Applicable Liquidity
Rate".

                  Section 3.08. Replacement of Borrower. From time to time and
subject to the successor Borrower's meeting the eligibility requirements set
forth in Section 6.9 of the Intercreditor Agreement applicable to the
Subordination Agent, upon the effective date and time specified in a written and
completed Notice of Replacement Subordination Agent in substantially the form of
Annex V attached hereto (a "Notice of Replacement Subordination Agent")
delivered to the Liquidity Provider by the then Borrower, the successor Borrower
designated therein shall be substituted for as the Borrower for all purposes
hereunder.

                  Section 3.09. Funding Loss Indemnification. The Borrower shall
pay to the Liquidity Provider, upon the request of the Liquidity Provider, such
amount or amounts as shall be sufficient (in the reasonable opinion of the
Liquidity Provider) to compensate it for any loss, cost, or expense incurred by
reason of the liquidation or redeployment of deposits or other funds acquired by
the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss
of anticipated profits) incurred as a result of:

                  (1) Any repayment of a LIBOR Advance on a date other than the
         last day of the Interest Period for such Advance; or

                  (2) Any failure by the Borrower to borrow a LIBOR Advance on
         the date for borrowing specified in the relevant notice under Section
         2.02.

                  Section 3.10. Illegality. Notwithstanding any other provision
in this Agreement, if any change in any applicable law, rule or regulation, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Liquidity Provider (or its Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful
or impossible for the Liquidity Provider (or its Lending Office) to maintain or
fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity
Provider, the outstanding principal amount of the LIBOR Advances shall be
converted to Base Rate Advances (a) immediately upon demand of the Liquidity
Provider, if such change or compliance with such request, in the judgment of the
Liquidity Provider, requires immediate repayment; or (b) at the expiration of
the last Interest Period to expire before the effective date of any such change
or request.

Effective Date: No event has occurred and is continuing, or would result from

         discuss such transactions.

                  (c) Certain Operative Agreements. Furnish to the Liquidity
         Provider with reasonable promptness such Operative Agreements entered
         into after the date hereof as from time to time may be reasonably
         requested by the Liquidity Provider.

any Advance shall remain unpaid or the Liquidity Provider shall have any Maximum
Commitment hereunder or the Borrower shall have any obligation to pay any amount
to the Liquidity Provider hereunder, the Borrower will not appoint or permit or
suffer to be appointed any successor Borrower without the prior written consent
of the Liquidity Provider, which consent shall not be unreasonably withheld or
delayed.

The Liquidity Provider shall be indemnified hereunder to the extent and in the
manner described in Section 9.1 of the Leased Aircraft Participation Agreement,
Section 8.1 of the Owned Aircraft Participation Agreement and Section 6 of the
Note Purchase Agreement. In addition, the Borrower agrees to indemnify, protect,
defend and hold harmless the Liquidity Provider from, against and in respect of,
and shall pay on demand, all Expenses of any kind or nature whatsoever (other
than any Expenses of the nature described in Sections 3.01, 3.02 or 7.07 hereof
or in the MSCS Fee Letter (regardless of whether indemnified against pursuant to
said Sections or in such MSCS Fee Letter)), that may be imposed, incurred by or
asserted against any Liquidity Indemnitee, in any way relating to, resulting
from, or arising out of or in connection with any action, suit or proceeding by
any third party against such Liquidity Indemnitee and relating to this
Agreement, the MSCS Fee Letter, the Intercreditor Agreement or any Financing
Agreement; provided, however, that the Borrower shall not be required to
indemnify, protect, defend and hold harmless any Liquidity Indemnitee in respect
of any Expense of such Liquidity Indemnitee (i) to the extent such Expense is
attributable to the gross negligence or willful misconduct of such Liquidity
Indemnitee or any other Liquidity Indemnitee, (ii) ordinary and usual operating
overhead expense, or (iii) attributable to the failure by such Liquidity
Indemnitee or any other Liquidity Indemnitee to perform or observe any
agreement, covenant or condition on its part to be performed or observed in this
Agreement, the Intercreditor Agreement, the MSCS Fee Letter or any other
Operative Agreement to which it is a party. The indemnities contained in Section
9.1 or 8.1, as the case may be, of the Participation Agreements, and the
provisions of Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall

the Advances or any acts or omissions of the Borrower or any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; or (iii) the making of Advances by the Liquidity Provider against
delivery of a Notice of Borrowing and other documents which do not comply with
the terms hereof; provided, however, that the Borrower shall have a claim
against the Liquidity Provider, and the Liquidity Provider shall be liable to
the Borrower, to the extent of any damages suffered by the Borrower which were
the result of (A) the Liquidity Provider's willful misconduct or negligence in
determining whether documents presented hereunder comply with the terms hereof,
or (B) any breach by the Liquidity Provider of any of the terms of this
Agreement, including, but not limited to, the Liquidity Provider's failure to
make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly complying with the terms and conditions hereof.

                  (b) Neither the Liquidity Provider nor any of its officers,
employees, director or affiliates shall be liable or responsible in any respect
for (i) any error, omission, interruption or delay in transmission, dispatch or
delivery of any message or advice, however transmitted, in connection with this
Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action,
inaction or omission which may be taken by it in good faith, absent willful
misconduct or negligence (in which event the extent of the Liquidity Provider's
potential liability to the Borrower shall be limited as set forth in the
immediately preceding paragraph), in connection with this Agreement or any
Notice of Borrowing.

                  Section 7.07. Costs, Expenses and Taxes. The Borrower agrees
to pay, or cause to be paid (A) on the Effective Date and on such later date or
dates on which the Liquidity Provider shall make demand, all reasonable
out-of-pocket costs and expenses (including, without limitation, the reasonable
fees and expenses of outside counsel for the Liquidity Provider) of the
Liquidity Provider in connection with the preparation, negotiation, execution,
delivery, filing and recording of this Agreement, any other Operative Agreement
and any other documents which may be delivered in connection with this Agreement
and (B) on demand, all reasonable costs and expenses (including reasonable
counsel fees and expenses) of the Liquidity Provider in connection with (i) the
enforcement of this Agreement or any other Operative Agreement, (ii) the
modification or amendment of, or supplement to, this Agreement or any other
Operative Agreement or such other documents which may be delivered in connection
herewith or therewith (whether or not the same shall become effective) or (iii)
any action or proceeding relating to any order, injunction, or other process or
decree restraining or seeking to restrain the Liquidity Provider from paying any
amount under this Agreement, the Intercreditor Agreement or any other Operative
Agreement or otherwise affecting the application of funds in the Class C Cash
Collateral Account. In addition, the Borrower shall pay any and all recording,
stamp and other similar taxes and fees payable or determined to be payable in
connection with the execution, delivery, filing and recording of this Agreement,
any other Operative Agreement and such other documents, and agrees to save the
Liquidity Provider harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such taxes
or fees.

                  Section 7.08. Binding Effect; Participations.

                  (a) This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective
successors and assigns, except that neither the Liquidity Provider (except as
otherwise provided in this Section 7.08) nor (except as contemplated by Section
3.08) the Borrower shall have the right to assign its rights or obligations
hereunder or any interest herein without the prior written consent of the other
party, subject to the requirements of Section 7.08(b). The Liquidity Provider
may grant participations herein or in any of its rights hereunder (including,
without limitation, funded participations and participations in rights to
receive interest payments hereunder) and under the other Operative Agreements to
such Persons as (not including Atlas or any affiliate of Atlas) the Liquidity
Provider may in its sole discretion select, subject to the requirements of
Section 7.08(b). No such participation by the Liquidity Provider, however, will
relieve the Liquidity Provider of its obligations hereunder. In

                                       23
<PAGE>   28

connection with any participation or any proposed participation, the Liquidity
Provider may disclose to the participant or the proposed participant any
information that the Borrower is required to deliver or to disclose to the
Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and
agrees that the Liquidity Provider's source of funds may derive in part from its
participants. Accordingly, references in this Agreement and the other Operative
Agreements to determinations, reserve and capital adequacy requirements,
increased costs, reduced receipts, additional amounts due pursuant to Section
3.03(a) and the like as they pertain to the Liquidity Provider shall be deemed
also to include those of each of its participants (subject, in each case, to the
maximum amount that would have been incurred by or attributable to the Liquidity
Provider directly if the Liquidity Provider, rather than the participant, had
held the interest participated).

                  (b) If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity
(each, a "Transferee"), then, concurrently with the effectiveness of such
participation, the Transferee shall (i) represent to the Liquidity Provider (for
the benefit of the Liquidity Provider and the Borrower) either (A) that it is
incorporated under the laws of the United States or a state thereof or (B) that
under applicable law and treaties, no taxes will be required to be withheld with
respect to any payments to be made to such Transferee in respect of this
Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a
statement that it is incorporated under the laws of the United States or a state
thereof or (y) if it is not so incorporated, two copies of a properly completed
United States Internal Revenue Service Form W-8 ECI or Form W-8 BEN, as
appropriate, or other applicable form, certificate or document prescribed by the
Internal Revenue Service certifying, in each case, such Transferee's entitlement
to a complete exemption from United States federal withholding tax in respect to
any and all payments to be made hereunder, and (iii) agree (for the benefit of
the Liquidity Provider and the Borrower) to provide the Liquidity Provider and
the Borrower a new Form W-8 ECI or Form W-8 BEN, as appropriate, (A) on or
before the date that any such form expires or becomes obsolete or (B) after the
occurrence of any event requiring a change in the most recent form previously
delivered by it and prior to the immediately following due date of any payment
by the Borrower hereunder, certifying in the case of a Form W-8 BEN or Form W-8
ECI that such Transferee is entitled to a complete exemption from United States
federal withholding tax on payments under this Agreement. Unless the Borrower
has received forms or other documents reasonably satisfactory to it (and
required by applicable law) indicating that payments hereunder are not subject
to United States federal withholding tax, the Borrower will withhold taxes as
required by law from such payments at the applicable statutory rate.

                  Section 7.09. Severability. Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or nonauthorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

                  Section 7.10. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  Section 7.11. 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

                  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 to the venue of any such action or proceeding
                  in any such court or that 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 7.02 hereof, or at such other
                  address of which the Liquidity Provider 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) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE
TO WAIVE THEIR 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. The
Borrower and the Liquidity Provider each warrant and represent 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.

                  Section 7.12. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto on
separate counterparts, each of which counterparts, when so executed and
delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Agreement.

                  Section 7.13. Entirety. This Agreement, the Intercreditor
Agreement and the other Operative Agreements to which the Liquidity Provider is
a party constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and supersedes all prior understandings and agreements
of such parties.

                  Section 7.14. Headings. Section headings in this Agreement are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose.

                  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:

                  SECTION 1. Escrow Agent.

                  Section 1.01. Appointment of Escrow Agent. Each of the
Placement Agents, for and on behalf of each of the Investors, hereby irrevocably
appoints, authorizes and directs the Escrow Agent to act as escrow agent and
fiduciary hereunder and under the Deposit Agreement for such specific purposes
and with such powers as are specifically delegated to the Escrow Agent by the
terms of this Agreement, together with such other powers as are reasonably
incidental thereto. Any and all money received and held by the Escrow Agent
under this Agreement or the Deposit Agreement shall be held in escrow by the
Escrow Agent in accordance with the terms of this Agreement. This Agreement is
irrevocable and the Investors' rights with respect to any monies received and
held in escrow by the Escrow Agent under this Agreement or the Deposit Agreement
shall only be as provided under the terms and conditions of this Agreement and
the Deposit Agreement. The Escrow Agent (which term as used in this sentence
shall include reference to its affiliates and its own and its affiliates'
officers, directors, employees and agents): (a) shall have no duties or
responsibilities except those expressly set forth in this Agreement; (b) shall
not be responsible to the Pass Through Trustee or the Investors for any
recitals, statements, representations or warranties of any person other then
itself contained in this Agreement or the Deposit Agreement or for the failure
by the Pass Through Trustee, the Investors or any other person or entity (other
than the Escrow Agent) to perform any of its obligations hereunder (whether or
not the Escrow Agent shall have any knowledge thereof); and (c) shall not be
responsible for any action taken or omitted to be taken by it hereunder or
provided for herein or in connection herewith, except for its own willful
misconduct or gross negligence (or simple negligence in connection with the
handling of funds).

                  Section 1.02. Instruction; Etc. The Placement Agents, for and
on behalf of each of the Investors, hereby irrevocably instruct the Escrow
Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement, (b)
to appoint the Paying Agent as provided in this Agreement, (c) upon receipt at
any time and from time to time prior to the Delivery Period Termination Date (as
defined in the Note Purchase Agreement) of a certificate substantially in

                                       2
<PAGE>   6

the form of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass
Through Trustee, together with an attached Notice of Purchase Withdrawal in
substantially the form of Exhibit A to the Deposit Agreement duly completed by
the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and the
withdrawal to which it relates, a "Purchase Withdrawal"), immediately to execute
the Applicable Notice of Purchase Withdrawal as Escrow Agent and transmit it to
the Depositary by facsimile transmission in accordance with the Deposit
Agreement; provided that, upon the request of the Pass Through Trustee after
such transmission, the Escrow Agent shall cancel such Applicable Notice of
Purchase Withdrawal, (d) upon receipt at any time and from time to time prior to
the Delivery Period Termination Date of a certificate substantially in the form
of Exhibit C hereto (a "Prepayment Withdrawal Certificate") executed by the Pass
Through Trustee, together with an attached Notice of Prepayment Withdrawal in
substantially the form of Exhibit B to the Deposit Agreement duly completed by
the Pass Through Trustee (the "Applicable Notice of Prepayment Withdrawal" and
the withdrawal to which it relates, a "Prepayment Withdrawal"), immediately to
execute the Applicable Notice of Prepayment Withdrawal as Escrow Agent and
transmit it to the Depositary by facsimile transmission in accordance with the
Deposit Agreement; provided that, upon the request of the Pass Through Trustee
after such transmission, the Escrow Agent shall cancel such Applicable Notice of
Prepayment Withdrawal, and (e) if there are any undrawn amounts in the Account
(as defined in the Deposit Agreement) on the earlier of (i) the Delivery Period
Termination Date and (ii) the date on which the Escrow Agent receives notice
from the Pass Through Trustee that the Pass Through Trustee's obligation to
purchase Equipment Notes under the Note Purchase Agreement has terminated, to
give notice to the Depositary (with a copy to the Paying Agent) substantially in
the form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of
the remaining amount of the Deposit (as defined in the Deposit Agreement),
together with accrued and unpaid interest on the Deposit to the date of
withdrawal, on the 15th day after the date that such notice of withdrawal is
given to the Depositary (or, if not a Business Day, on the next succeeding
Business Day) (a "Final Withdrawal"), provided that if the day scheduled for the
Final Withdrawal in accordance with the foregoing is within 10 days before a
Regular Distribution Date, then the Escrow Agent shall request that such
requested Final Withdrawal be made on such Regular Distribution Date (the date
of such requested withdrawal, the "Final Withdrawal Date"). If for any reason
the Escrow Agent shall have failed to give the Final Withdrawal Notice 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 (as defined in the Deposit Agreement) on such date, the Final Withdrawal
Date shall be deemed to be January 16, 2001 (or, if the December 31, 2000 date
has been extended as provided in this sentence, the fifteenth day after the
Delivery Period Termination Date).

                  Section 1.03. Initial Escrow Amount; Issuance of Escrow
Receipts. The Escrow Agent hereby directs the Placement Agents to, and the
Placement Agents hereby acknowledge that on the date hereof they shall,
irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount
in U.S. dollars ("Dollars") and immediately available funds equal to
$124,639,000 for deposit on behalf of the Escrow Agent with the Depositary in
accordance with Section 2.1 of the Deposit Agreement. The Placement Agents
hereby instruct the Escrow Agent,

                                       3
<PAGE>   7

upon receipt of such sum from the Placement Agents, to confirm such receipt by
executing and delivering to the Pass Through Trustee an Escrow Receipt in the
form of Exhibit A hereto (an "Escrow Receipt"), (a) to be affixed by the Pass
Through Trustee to each Certificate and (b) to evidence the same percentage
interest (the "Escrow Interest") in the Account Amounts (as defined below) as
the Fractional Undivided Interest in the Pass Through Trust evidenced by the
Certificate to which it is to be affixed. The Escrow Agent shall provide to the
Pass Through Trustee for attachment to each Certificate newly issued under and
in accordance with the Pass Through Trust Agreement an executed Escrow Receipt
as the Pass Through Trustee may from time to time request of the Escrow Agent.
Each Escrow Receipt shall be registered by the Escrow Agent in a register (the
"Register") maintained by the Escrow Agent in the same name and same manner as
the Certificate to which it is attached and may not thereafter be detached from
such Certificate to which it is to be affixed prior to the distribution of the
Final Withdrawal (the "Final Distribution"). After the Final Distribution, no
additional Escrow Receipts shall be issued and the Pass Through Trustee shall
request the return to the Escrow Agent for cancellation of all outstanding
Escrow Receipts.

                  Section 1.04. Payments to Receiptholders. All payments and
distributions made to holders of an Escrow Receipt (collectively
"Receiptholders") in respect of the Escrow Receipt shall be made only from
amounts deposited in the Paying Agent Account (as defined below) ("Account
Amounts"). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees
that (a) it will look solely to the Account Amounts for any payment or
distribution due to such Receiptholder pursuant to the terms of the Escrow
Receipt and this Agreement and (b) it will have no recourse to Atlas, the Pass
Through Trustee, the Paying Agent or the Escrow Agent, except as expressly
provided herein or in the Pass Through Trust Agreement. No Receiptholder shall
have any right to vote or in any manner otherwise control the operation and
management of the Paying Agent Account or the obligations of the parties hereto,
nor shall anything set forth herein, or contained in the terms of the Escrow
Receipt, be construed so as to constitute the Receiptholders from time to time
as partners or members of an association.

                  Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow
Receipt. If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent
or the Escrow Agent receives evidence to its satisfaction of the destruction,
loss or theft of any Escrow Receipt and (b) there is delivered to the Escrow
Agent and the Pass Through Trustee such security, indemnity or bond, as may be
required by them to hold each of them harmless, then, absent notice to the
Escrow Agent or the Pass Through Trustee that such destroyed, lost or stolen
Escrow Receipt has been acquired by a bona fide purchaser, and provided that the
requirements of Section 8-405 of the Uniform Commercial Code in effect in any
applicable jurisdiction are met, the Escrow Agent shall execute, authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like
Escrow Interest in the Account Amounts and bearing a number not
contemporaneously outstanding.

                  In connection with the issuance of any new Escrow Receipt
under this Section 1.05, the Escrow Agent may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the
Pass Through Trustee and the Escrow Agent) connected therewith.

                                       4
<PAGE>   8

                  Any duplicate Escrow Receipt issued pursuant to this Section
1.05 shall constitute conclusive evidence of the appropriate Escrow Interest in
the Account Amounts, as if originally issued, whether or not the lost, stolen or
destroyed Escrow Receipt shall be found at any time.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Escrow
Receipts.

                  Section 1.06. Additional Escrow Amounts. On the date of any
Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary
some or all of the amounts so withdrawn in accordance with Section 2.4 of the
Deposit Agreement.

                  Section 1.07. Resignation or Removal of Escrow Agent. Subject
to the appointment and acceptance of a successor Escrow Agent as provided below,
the Escrow Agent may resign at any time by giving 30 days' prior written notice
thereof to the Investors, but may not otherwise be removed except for cause by
the written consent of the Investors with respect to Investors representing
Escrow Interests aggregating not less than a majority in interest in the Account
Amounts (an "Action of Investors"). Upon any such resignation or removal, the
Investors, by an Action of Investors, shall have the right to appoint a
successor Escrow Agent. If no successor Escrow Agent shall have been so
appointed and shall have accepted such appointment within 30 days after the
retiring Escrow Agent's giving of notice of resignation or the removal of the
retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor
Escrow Agent. Any successor Escrow Agent shall be a bank which has an office in
the United States with a combined capital and surplus of at least $100,000,000.
Upon the acceptance of any appointment as Escrow Agent hereunder by a successor
Escrow Agent, such successor Escrow Agent shall enter into such documents as the
Pass Through Trustee shall require and shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Escrow
Agent, and the retiring Escrow Agent shall be discharged from its duties and
obligations hereunder. No resignation or removal of the Escrow Agent shall be
effective unless a written confirmation shall have been obtained from each of
Moody's Investors Service, Inc. and Standard & Poor's Rating Group, a division
of McGraw-Hill Inc. that the replacement of the Escrow Agent with the successor
Escrow Agent will not result in (a) a reduction of the rating for the
Certificates below the then current rating for the Certificates or (b) a
withdrawal or suspension of the rating of the Certificates.

                  Section 1.08. Persons Deemed Owners. Prior to due presentment
of a Certificate for registration of transfer, the Escrow Agent and the Paying
Agent may treat the Person in whose name any Escrow Receipt is registered (as of
the day of determination) as the owner of such Escrow Receipt for the purpose of
receiving distributions pursuant to this Agreement and for all other purposes
whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected
by any notice to the contrary.

                  Section 1.09. Further Assurances. The Escrow Agent agrees to
take such actions, and execute such other documents, as may be reasonably
requested by the Pass Through

                                       5

Trustee in order to effectuate the purposes of this Agreement and the
performance by the Escrow Agent of its obligations hereunder.

                  SECTION 2. Paying Agent.

                  Section 2.01. Appointment of Paying Agent. The Escrow Agent
hereby irrevocably appoints and authorizes the Paying Agent to act as its paying
agent hereunder, for the benefit of the Investors, for such specific purposes
and with such powers as are specifically delegated to the Paying Agent by the
terms of this Agreement, together with such other powers as are reasonably
incidental thereto. Any and all money received and held by the Paying Agent
under this Agreement or the Deposit Agreement shall be held in the Paying Agent
Account for the benefit of the Investors. The Paying Agent (which term as used
in this sentence shall include reference to its affiliates and its own and its
affiliates_ officers, directors, employees and agents): (a) shall have no duties
or responsibilities except those expressly set forth in this Agreement, and
shall not by reason of this Agreement be a trustee for the Escrow Agent; (b)
shall not be responsible to the Escrow Agent for any recitals, statements,
representations or warranties of any person other then itself contained in this
Agreement or for the failure by the Escrow Agent or any other person or entity
(other than the Paying Agent) to perform any of its obligations hereunder
(whether or not the Paying Agent shall have any knowledge thereof); and (c)
shall not be responsible for any action taken or omitted to be taken by it
hereunder or provided for herein or in connection herewith, except for its own
willful misconduct or gross negligence (or simple negligence in connection with
the handling of funds).

                  Section 2.02. Establishment of Paying Agent Account. The
Paying Agent shall establish a deposit account (the "Paying Agent Account") at
Wilmington Trust Company in the name of the Escrow Agent. It is expressly
understood by the parties hereto that the Paying Agent is acting as the paying
agent of the Escrow Agent hereunder and that no amounts on deposit in the Paying
Agent Account constitute part of the Trust Property.

                  Section 2.03. Payments from Paying Agent Account. The Escrow
Agent hereby irrevocably instructs the Paying Agent, and the Paying Agent agrees
to act, as follows:

                  (a) On each Interest Payment Date (as defined in the Deposit
         Agreement) or as soon thereafter as the Paying Agent has confirmed
         receipt in the Paying Agent Account from the Depositary of any amount
         in respect of accrued interest on the Deposit, the Paying Agent shall
         distribute out of the Paying Agent Account the entire amount deposited
         therein by the Depositary. There shall be so distributed to each
         Receiptholder of record on the 15th day (whether or not a Business Day)
         preceding such Interest Payment Date by check mailed to such
         Receiptholder, at the address appearing in the Register, such
         Receiptholder's pro rata share (based on the Escrow Interest in the
         Account Amounts held by such Receiptholder) of the total amount of
         interest deposited by the Depositary in the Paying Agent Account on
         such date, except that, with respect to Escrow Receipts registered on
         the record date in the name of a nominee of the Depository Trust
         Company ("DTC"), such distribution shall be made by wire transfer in
         immediately available funds to the account designated by DTC.

                                       6
<PAGE>   10

                  (b) Upon the confirmation by the Paying Agent of receipt in
         the Paying Agent Account from the Depositary of any amount in respect
         of the Final Withdrawal, the Paying Agent shall forthwith distribute
         the entire amount of the Final Withdrawal deposited therein by the
         Depositary. There shall be so distributed to each Receiptholder of
         record on the 15th day (whether or not a Business Day) preceding the
         Final Withdrawal Date by check mailed to such Receiptholder, at the
         address appearing in the Register, such Receiptholder's pro rata share
         (based on the Escrow Interest in the Account Amounts held by such
         Receiptholder) of the total amount in the Paying Agent Account on
         account of such Final Withdrawal, except that, with respect to Escrow
         Receipts registered on the record date in the name of a nominee of DTC,
         such distribution shall be made by wire transfer in immediately
         available funds to the account designated by DTC.

                  (c) If any payment of interest or principal in respect of the
         Final Withdrawal is not received by the Paying Agent within five days
         of the applicable date when due, then it shall be distributed to
         Receiptholders after actual receipt by the Paying Agent on the same
         basis as a Special Payment is distributed under the Pass Through Trust
         Agreement.

                  (d) Upon the confirmation by the Paying Agent of receipt in
         the Paying Agent Account from the Depositary of any amount in respect
         of a Prepayment Withdrawal, the Paying Agent shall forthwith distribute
         the entire amount of such Prepayment Withdrawal upon not less than 15
         days prior notice to the Receiptholders. There shall be distributed to
         each Receiptholder of record on the 15th day (whether or not a Business
         Day) preceding such date of distribution by check mailed to such
         Receiptholder, at the address appearing in the Register, such
         Receiptholder's pro rata share (based on the Escrow Interest in the
         Account Amounts held by such Receiptholder) of the total amount in the
         Paying Agent Account on account of such Prepayment Withdrawal, except
         that, with respect to the Escrow Receipts registered on such record
         date in the name of a nominee of DTC, such distribution shall be made
         by wire transfer in immediately available funds to the account
         designated by DTC.

                  (e) The Paying Agent shall include with any check mailed
         pursuant to this Section any notice required to be distributed under
         the Pass Through Trust Agreement that is furnished to the Paying Agent
         by the Pass Through Trustee.

                  Section 2.04. Withholding Taxes. The Paying Agent shall
exclude and withhold from each distribution of accrued interest on the Deposit
(as defined in the Deposit Agreement) and any amount in respect of any
Prepayment Withdrawal and the Final Withdrawal any and all withholding taxes
applicable thereto as required by law. The Paying Agent agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any amounts
payable in respect of the Deposit (as defined in the Deposit Agreement) or the
escrow amounts, to withhold such amounts and timely pay the same to the
appropriate authority in the name of and on behalf of the Receiptholders, that
it will file any necessary withholding tax returns or statements when due,

                                       7
<PAGE>   11

and that, as promptly as possible after the payment thereof, it will deliver to
each such Receiptholder appropriate documentation showing the payment thereof,
together with such additional documentary evidence as such Receiptholder may
reasonably request from time to time. The Paying Agent agrees to file any other
information reports as it may be required to file under United States law.

                  Section 2.05. Resignation or Removal of Paying Agent. Subject
to the appointment and acceptance of a successor Paying Agent as provided below,
the Paying Agent may resign at any time by giving 30 days' prior written notice
thereof to the Escrow Agent, but may not otherwise be removed except for cause
by the Escrow Agent. Upon any such resignation or removal, the Escrow Agent
shall have the right to appoint a successor Paying Agent. If no successor Paying
Agent shall have been so appointed and shall have accepted such appointment
within 30 days after the retiring Paying Agent's giving of notice of resignation
or the removal of the retiring Paying Agent, then the retiring Paying Agent may
appoint a successor Paying Agent. Any Successor Paying Agent shall be a bank
which has an office in the United States with a combined capital and surplus of
at least $100,000,000. Upon the acceptance of any appointment as Paying Agent
hereunder by a successor Paying Agent, such successor Paying Agent shall enter
into such documents as the Escrow Agent shall require and shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Paying Agent, and the retiring Paying Agent shall be discharged
from its duties and obligations hereunder.

                  Section 2.06. Notice of Prepayment Withdrawal and Final
Withdrawal. Promptly after receipt by the Paying Agent of notice that the Escrow
Agent has requested a Prepayment Withdrawal or a Final Withdrawal or that a
Prepayment Withdrawal or a Final Withdrawal will be made, the Paying Agent shall
cause notice of such distribution to be mailed to each of the Receiptholders at
its address as it appears in the Register. Such notice shall be mailed not less
than 15 days prior to the distribution date of such Prepayment Withdrawal (the
"Prepayment Withdrawal Date") or of the Final Withdrawal Date, as the case may
be. Such notice shall set forth:

                  (i) the Prepayment Withdrawal or the Final Withdrawal Date, as
         the case may be, and the date for determining Receiptholders of record
         who shall be entitled to receive distributions in respect of the
         Prepayment Withdrawal or Final Withdrawal,

                  (ii) the amount of the payment in respect of the Prepayment
         Withdrawal or Final Withdrawal, as the case may be, for each $1,000
         face amount Certificate (based on information provided by the Pass
         Through Trustee) and the amount thereof constituting the unused portion
         of the Deposit (as defined in the Deposit Agreement) and interest
         thereon, and

                  (iii) if the Prepayment Withdrawal Date or Final Withdrawal
         Date is the same date as a Regular Distribution Date, the total amount
         to be received on such date for each $1,000 face amount Certificate

Certificateholders in connection with such distribution pursuant to the Pass
Through Trust Agreement.

                  SECTION 3. Payments. If, notwithstanding the instructions in
Section 4 of the Deposit Agreement that all amounts payable to the Escrow Agent
under the Deposit Agreement be paid by the Depositary directly to the Paying
Agent or the Pass Through Trustee (depending on the circumstances), the Escrow
Agent receives any payment thereunder, then the Escrow Agent shall forthwith pay
such amount in Dollars and in immediately available funds by wire transfer to
(a) in the case of a payment of accrued interest on the Deposit (as defined in
the Deposit Agreement), any Prepayment Withdrawal or any Final Withdrawal,
directly to the Paying Agent Account and (b) in the case of any Purchase
Withdrawal, directly to the Pass Through Trustee or its designee as specified
and in the manner provided in the Applicable Notice of Purchase Withdrawal. The
Escrow Agent 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 amounts payable to the Paying
Agent howsoever arising.

                  SECTION 4. Other Actions. The Escrow Agent shall take such
other actions under or in respect of the Deposit Agreement (including, without

         governmental authority, arbitration board or administrative agency so
         as to adversely affect its ability to perform its obligations under

or represents no rights, benefits or interests of any kind in respect of any
assets or property other than such amounts. This Escrow Receipt evidences the
same percentage interest in the Account Amounts as the Fractional Undivided
Interest in the Pass Through Trust evidenced by the Certificate to which this
Escrow Receipt is affixed.

                  All payments and distributions made to Receiptholders in
respect of the Escrow Receipt shall be made only from Account Amounts deposited
in the Paying Agent Account. The holder of this Escrow Receipt, by its
acceptance of this Escrow Receipt, agrees that it will look solely to the
Account Amounts for any payment or distribution due to it pursuant to this
Escrow Receipt and that it will not have any recourse to Atlas, the Pass Through
Trustee, the Paying Agent or the Escrow Agent, except as expressly provided
herein or in the Pass Through Trust Agreement. No Receiptholder of this Escrow
Receipt shall have any right to vote or in any manner otherwise control the
operation and management of the Paying Agent Account, nor shall anything set
forth herein, or contained in the terms of this Escrow Receipt, be construed so
as to constitute the Receiptholders from time to time as partners or members of
an association.

                  This Escrow Receipt may not be assigned or transferred except
in connection with the assignment or transfer of the Certificate to which this
Escrow Receipt is affixed. After payment to the holder hereof of its Escrow
Interest in the Final Distribution, upon the request of

the Pass Through Trustee, the holder hereof will return this Escrow Receipt to
the Pass Through Trustee.

                  The Paying Agent may treat the person in whose name the
Certificate to which this Escrow Receipt is attached as the owner hereof for all
purposes, and the Paying Agent shall not be affected by any notice to the
contrary.

                  THIS ESCROW RECEIPT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                  IN WITNESS WHEREOF, the Escrow Agent has caused this Escrow
Receipt to be duly executed.
