          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

Maximum Commitment at such time and shall be used solely for the payment when
due of the interest on the Class B Certificates at the Stated Interest Rate

Interest Advance made hereunder shall automatically reduce the Maximum
Commitment and the amount available to be borrowed hereunder by subsequent

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),

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

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 B Cash Collateral Account in

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 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 B 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

attached hereto, signed by a Responsible Officer of the

be used to fund the Class B 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

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 B Cash
Collateral Account, the Liquidity Provider shall have no interest in or rights
to the Class B Cash Collateral Account, such Advance or any other amounts from
time to time on deposit in the Class B 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

          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 B 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.

Cash Collateral Account, invested and withdrawn from the Class B 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

such Provider Advance as provided in Section 3.07; provided, however, that

    -----------------------------

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 B 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 B Cash Collateral Account

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 B Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider,

Intercreditor Agreement, to the extent payable to the Liquidity Provider

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.

                         ------------
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.

that constitute Scheduled Payments, Special Payments or payments under Section
7.01 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 and shall have no liability under this Agreement except as
expressly provided in this Agreement, the Intercreditor Agreement or any

                         ---------------------------------------------------

the terms hereof),

                                      14

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
25/th/ 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 25/th/ 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.  If the Liquidity Provider shall
                         ---------------
reasonably determine that (a) any change, after the Effective Date, in any law
or regulation or in the interpretation thereof by any court or administrative or
governmental authority charged with the administration thereof or in the
compliance by the Liquidity Provider(or any corporation controlling the
Liquidity Provider) with any applicable direction, request or requirement
(whether or not having the force of law) of any central bank or competent
governmental or other authority shall impose, modify or deem applicable any
reserve, special deposit or similar requirement against assets held by, or
deposits in or for the account of, or loans or loan commitments made by, the
Liquidity Provider pursuant to this Agreement and (b) the result of any event
referred to in clause (a) shall be to increase the cost to the Liquidity
Provider of issuing or maintaining its commitment hereunder or funding or
maintaining Advances (which increase in cost shall be determined by the
Liquidity Provider's reasonable allocations of the aggregate of such cost
increases resulting from such event among similarly affected credit and funding
facilities), or to reduce the amount of any sum received or receivable by the
Liquidity Provider under this Agreement with respect thereto, then, upon demand
by the Liquidity Provider (such demand to be made as soon as practicable, but
not later than 30 days after a Responsible Officer of the Liquidity Provider
obtains or reasonably should have obtained knowledge of any event referred to in
clause (a) above), and subject to Section 2.09, the Borrower shall pay, or cause
to be paid, to the Liquidity Provider, from time to time as specified by the
Liquidity Provider, additional amounts which shall be sufficient to compensate
the Liquidity Provider for such increased cost or reduction; provided that if
such demand for payment is made after such 30-day period, the Borrower shall be
obligated to pay such additional amounts only with respect to such increased
cost or reduction actually incurred or effected on or after the 30th day prior
to the date of such demand.  A certificate as to such increased cost or
reduction (which shall set forth in reasonable detail the basis for such
increased cost on reduction) incurred by the Liquidity Provider as a result of
any event mentioned in clause (a) above, prepared in reasonable detail and
submitted by the Liquidity Provider to the Borrower, shall be conclusive, absent
manifest error, as to the amount thereof.

                                      15

          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 amount payable under this Section 3.01 that
may thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous in any material respect to the Liquidity
Provider. The Liquidity Provider agrees that if it shall make a demand for
payment of additional amounts under this Section the Borrower shall have the
right to obtain a Replacement Liquidity Facility in replacement of this
Agreement in accordance with Section 3.6(e) of the Intercreditor Agreement.

          Section 3.02   Capital Adequacy.  If the Liquidity Provider shall
                         ----------------
reasonably determine that the adoption, after the Effective Date, of any
applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change, after the Effective Date, 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 any corporation controlling the Liquidity
Provider) with any request or directive regarding capital adequacy (whether or
not having the force of law) of any such authority, central bank or comparable
agency, 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) as a consequence of issuing or maintaining
its commitment hereunder or its funding or maintaining Advances and such
increase is based upon the Liquidity Provider's obligations hereunder and in
respect of similar obligations, then, upon demand by the Liquidity Provider
(such demand to be made as soon as is practicable, but not later than 30 days
after a Responsible Officer of the Liquidity Provider obtains or should
reasonably have obtained knowledge of any event referred to above in this
Section 3.02), and subject to Section 2.09, the Borrower shall pay to the
Liquidity Provider, from time to time as specified by the Liquidity Provider,
additional amounts (which amounts shall be determined by the Liquidity
Provider's reasonable allocations of the aggregate of such amounts resulting
from such event among similarly affected credit and funding facilities) which
shall be sufficient to compensate the Liquidity Provider for such increase in
respect of issuing or maintaining its commitment hereunder or its funding or
maintaining Advances; provided that, if such demand for payment is made after
such 30 day period, the Borrower shall be obligated to pay such amounts only
with respect to such increase actually effected on or after the 30th day prior
to the date of such demand.  A certificate describing the event (including
setting forth the necessary calculations) resulting in the demand for
compensation by the Liquidity Provider under this Section, prepared in
reasonable detail and submitted by the Liquidity Provider to the Borrower, shall
be conclusive, absent manifest error, as to the amount thereof.

          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 amount
<PAGE>

                                      16

payable under this Section 3.02 that may thereafter accrue and would not, in the
reasonable judgment of the Liquidity Provider, be otherwise disadvantageous in
any material respect to the Liquidity Provider. The Liquidity Provider agrees
that if it shall make a demand for payment of additional amounts under this
Section the Borrower shall have the right to obtain a Replacement Liquidity
Facility in replacement of this Agreement in accordance with Section 3.6(e) of
the Intercreditor Agreement.

          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 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
<PAGE>

                                      17

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 No. 021000089, Account Name: Morgan Stanley Capital Services Inc., Account
No. 407-24-601, Reference: Midway Airlines, 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 B Cash Collateral
Account to pay interest on the Class B 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 B 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
<PAGE>

                                      18

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 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,
<PAGE>

                                      19

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".

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.

Agreement, including, but not limited to, the Liquidity Provider's failure to

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

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 Midway or any affiliate of Midway) 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 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, where such participant
is not (i) a bank organized under the laws of the United States or any State
thereof and (ii) a member of the Federal Reserve System with deposits exceeding
$1,000,000,000 (a bank described in (i) and (ii) above being a "Reference
Bank"), to
<PAGE>

                                      27

the maximum amount that would have been incurred by or attributable to a
Reference Bank directly if such Reference Bank, 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,

           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.

requirement of a prior proceeding against MSCS and protest or notice except as
provided for in the Agreement with respect to amounts payable by MSCS.  If at

MSCS or MSDW or otherwise, MSDW's obligations hereunder with respect to such
payment shall be reinstated upon such restoration or return being made by
Counterpart.

                      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

                         -------------------

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

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 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

written and completed Notice of Borrowing in substantially the form of Annex IV
attached hereto, signed by a Responsible Officer of the

                                      10

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 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

and requested.

                         ----
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

    -------------------------
an "Applied Non-Extension Advance" and, together with an Applied Downgrade
    -----------------------------

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

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,

or, if not provided for in the Intercreditor Agreement, then in such manner as
the Liquidity Provider shall deem appropriate.

                         ------------
accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower resulting from Advances made from time to time and

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

that constitute Scheduled Payments, Special Payments or payments under Section
7.01 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 and shall have no 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)

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
25/th/ 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 25/th/ 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.  If the Liquidity Provider shall
                         ---------------
reasonably determine that (a) any change, after the Effective Date, in any law
or regulation or in the interpretation thereof by any court or administrative or
governmental authority charged with the administration thereof or in the
compliance by the Liquidity Provider(or any corporation controlling the
Liquidity Provider) with any applicable direction, request or requirement
(whether or not having the force of law) of any central bank or competent
governmental or other authority shall impose, modify or deem applicable any
reserve, special deposit or similar requirement against assets held by, or
deposits in or for the account of, or loans or loan commitments made by, the
Liquidity Provider pursuant to this Agreement and (b) the result of any event
referred to in clause (a) shall be to increase the cost to the Liquidity
Provider of issuing or maintaining its commitment hereunder or funding or
maintaining Advances (which increase in cost shall be determined by the
Liquidity Provider's reasonable allocations of the aggregate of such cost
increases resulting from such event among similarly affected credit and funding
facilities), or to reduce the amount of any sum received or receivable by the
Liquidity Provider under this Agreement with respect thereto, then, upon demand
by the Liquidity Provider (such demand to be made as soon as practicable, but
not later than 30 days after a Responsible Officer of the Liquidity Provider
obtains or reasonably should have obtained knowledge of any event referred to in
clause (a) above), and subject to Section 2.09, the Borrower shall pay, or cause
to be paid, to the Liquidity Provider, from time to time as specified by the
Liquidity Provider, additional amounts which shall be sufficient to compensate
the Liquidity Provider for such increased cost or reduction; provided that if
such demand for payment is made after such 30-day period, the Borrower shall be
obligated to pay such additional amounts only with respect to such increased
cost or reduction actually incurred or effected on or after the 30th day prior
to the date of such demand.  A certificate as to such increased cost or
reduction (which shall set forth in reasonable detail the basis for such
increased cost on reduction) incurred by the Liquidity Provider as a result of
any event mentioned in clause (a) above, prepared in reasonable detail and
submitted by the Liquidity Provider to the Borrower, shall be conclusive, absent
manifest error, as to the amount thereof.

                                      15

          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 amount payable under this Section 3.01 that
may thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous in any material respect to the Liquidity
Provider. The Liquidity Provider agrees that if it shall make a demand for
payment of additional amounts under this Section the Borrower shall have the
right to obtain a Replacement Liquidity Facility in replacement of this
Agreement in accordance with Section 3.6(e) of the Intercreditor Agreement.

          Section 3.02   Capital Adequacy.  If the Liquidity Provider shall
                         ----------------
reasonably determine that the adoption, after the Effective Date, of any
applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change, after the Effective Date, 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 any corporation controlling the Liquidity
Provider) with any request or directive regarding capital adequacy (whether or
not having the force of law) of any such authority, central bank or comparable
agency, 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) as a consequence of issuing or maintaining
its commitment hereunder or its funding or maintaining Advances and such
increase is based upon the Liquidity Provider's obligations hereunder and in
respect of similar obligations, then, upon demand by the Liquidity Provider
(such demand to be made as soon as is practicable, but not later than 30 days
after a Responsible Officer of the Liquidity Provider obtains or should
reasonably have obtained knowledge of any event referred to above in this
Section 3.02), and subject to Section 2.09, the Borrower shall pay to the
Liquidity Provider, from time to time as specified by the Liquidity Provider,
additional amounts (which amounts shall be determined by the Liquidity
Provider's reasonable allocations of the aggregate of such amounts resulting
from such event among similarly affected credit and funding facilities) which
shall be sufficient to compensate the Liquidity Provider for such increase in
respect of issuing or maintaining its commitment hereunder or its funding or
maintaining Advances; provided that, if such demand for payment is made after
such 30 day period, the Borrower shall be obligated to pay such amounts only
with respect to such increase actually effected on or after the 30th day prior
to the date of such demand.  A certificate describing the event (including
setting forth the necessary calculations) resulting in the demand for
compensation by the Liquidity Provider under this Section, prepared in
reasonable detail and submitted by the Liquidity Provider to the Borrower, shall
be conclusive, absent manifest error, as to the amount thereof.

          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 amount
<PAGE>

                                      16

payable under this Section 3.02 that may thereafter accrue and would not, in the
reasonable judgment of the Liquidity Provider, be otherwise disadvantageous in
any material respect to the Liquidity Provider. The Liquidity Provider agrees
that if it shall make a demand for payment of additional amounts under this
Section the Borrower shall have the right to obtain a Replacement Liquidity
Facility in replacement of this Agreement in accordance with Section 3.6(e) of
the Intercreditor Agreement.

          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 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
<PAGE>

                                      17

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 No. 021000089, Account Name: Morgan Stanley Capital Services Inc., Account
No. 407-24-601, Reference: Midway Airlines, 2000-1C.

          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
<PAGE>

                                      18

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 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".

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

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.

Agreement, including, but not limited to, the Liquidity Provider's failure to

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

immediately preceding paragraph), in connection with this Agreement or any
Notice of Borrowing.

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

Provider from paying any amount under this Agreement, the Intercreditor

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 Midway or any affiliate of Midway) 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 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, where such participant
is not (i) a bank organized under the laws of the United States or any State
thereof and (ii) a member of the Federal Reserve System with deposits exceeding
$1,000,000,000 (a bank described in (i) and (ii) above being a "Reference
Bank"), to
<PAGE>

                                      27

the maximum amount that would have been incurred by or attributable to a
Reference Bank directly if such Reference Bank, 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.

           courts, and waives any objection that it may now or hereafter have to

           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

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.

              ----
Counterparty, with effect from the date of the Agreement, the due and punctual
payment of all amounts payable by MSCS under the Agreement when the same shall
become due and payable, whether on scheduled payment dates, upon demand, upon
declaration of termination or otherwise, in accordance with the terms of the
Agreement and giving effect to any applicable grace period. Upon failure of MSCS
punctually to pay any such amounts, and upon written demand by Counterparty to
MSDW at its address set forth in the signature block of this Guarantee (or to
such other address as MSDW may specify in writing), MSDW agrees to pay or cause
to be paid such amounts; provided that delay by Counterparty in giving such
demand shall in no event affect MSDW's obligations under this Guarantee.

          MSDW hereby agrees that its obligations hereunder shall be
unconditional and will not be discharged except by complete payment of the
amounts payable under the Agreement, irrespective of any claim as to the
Agreement's validity, regularity or enforceability or the lack of authority of
MSCS to execute or deliver the Agreement, or any change in or amendment to the

provisions thereof, or the absence of any action to enforce the Agreement or the
recovery of any judgment against MSCS or of any action to enforce a judgment

otherwise constitute a legal or equitable discharge or defense of a guarantor

or otherwise (except as provided hereinabove), filing of claims requirement of a
prior proceeding against MSCS and protest or notice except as provided for in
the Agreement with respect to amounts payable by MSCS. If at any time payment
under the Agreement is rescinded or must be otherwise restored or returned by
Counterparty upon the insolvency, bankruptcy or reorganization of MSCS or MSDW
or otherwise, MSDW's obligations hereunder with respect to such payment shall be
reinstated upon such restoration or return being made by Counterpart.

Counterparty agrees that MSDW shall be subrogated to all rights of Counterparty
against MSCS in respect of any amounts paid by MSDW pursuant to this Guarantee,
