         Section 2.01. The Advances. The Primary 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 Primary 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 of Advances. (a) Each Interest Advance shall be
made by the Primary Liquidity Provider upon delivery to the Primary Liquidity
Provider (with a copy to the Policy Provider) of a written and completed Notice
of Borrowing in substantially the form of Annex I, signed by a Responsible
Officer of the Borrower, such Interest Advance to be in an amount not exceeding
the Maximum Available Commitment at such time and used solely for the payment
when due of interest with respect to the Class G Certificates at the Stated
Interest Rate therefor in accordance with Section 3.06(a) and 3.06(b) of the

automatically reduce the Maximum Available Commitment and the amount available

Advance (subject to reinstatement as provided in the next sentence). Subject to
the provisions of Section 3.06(g) of the Intercreditor Agreement, upon repayment

<PAGE>

the Primary Liquidity Provider in full or in part 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 Available Commitment shall be
reinstated by an amount equal to the amount of such Interest Advance so repaid,
but not to exceed the Maximum Commitment; provided, however, that the Maximum
Available Commitment shall not be so reinstated at any time if (x) both a
Performing Note Deficiency exists and a Liquidity Event of Default shall have
occurred and be continuing or (y) a Final Drawing shall have occurred.

         (b)      [Reserved]

         (c)      A Downgrade Advance shall be made by the Primary Liquidity
Provider (as provided for in Section 3.06(c) of the Intercreditor Agreement) if
at any time the short-term unsecured debt rating (in the case of Moody's) or
short-term issuer credit rating (in the case of S&P) of the Primary Liquidity
Provider issued by Moody's or S&P, respectively, (or if the Primary Liquidity
Provider does not have a short-term unsecured debt rating or short-term issuer
credit rating, as applicable, issued by a given Rating Agency, the long-term
unsecured debt rating (in the case of Moody's) or long-term issuer credit rating
(in the case of S&P) of the Primary Liquidity Provider issued by such Rating
Agency) is lower than the applicable Threshold Rating unless a Replacement
Primary Liquidity Facility to replace this Agreement shall have been previously
delivered to the Borrower in accordance with said Section 3.06(c), upon delivery
to the Primary Liquidity Provider (with a copy to the Policy Provider) of a
written and completed Notice of Borrowing in substantially the form of Annex II,
signed by a Responsible Officer of the Borrower, in an amount equal to the
Maximum Available Commitment at such time, and shall be used to fund the Primary
Cash Collateral Account in accordance with Sections 3.06(c) and 3.06(f) of the
Intercreditor Agreement.

         (d)      A Final Advance shall be made by the Primary Liquidity
Provider following the receipt by the Borrower of a Termination Notice from the
Primary Liquidity Provider pursuant to Section 6.01 upon delivery to the Primary
Liquidity Provider (with a copy to the Policy Provider) of a written and
completed Notice of Borrowing in substantially the form of Annex III, signed by
a Responsible Officer of the Borrower, in an amount equal to the Maximum
Available Commitment at such time, and shall be used to fund the Primary Cash
Collateral Account (in accordance with Sections 3.06(f) and 3.06(i) 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(c) or
2.02(d), as the case may be, given by the Borrower to the Primary Liquidity
Provider (with a copy to the Policy Provider). If a Notice of Borrowing is
delivered by the Borrower in respect of any Borrowing no later than 1:00 p.m.
(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
Primary Liquidity Provider shall make available to the Borrower, in accordance
with its payment instructions, the amount of such Borrowing in Dollars and
immediately available funds, before 4:00 p.m. (New York City time) on such
Business Day or before 1:00 p.m. (New York City time) 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 p.m. (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 Primary Liquidity
Provider shall make available to the Borrower, in accordance


                                       9
<PAGE>

with its payment instructions, the amount of such Borrowing in Dollars and
immediately available funds, before 1:00 p.m. (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
Primary Liquidity Provider for such purpose. Each Notice of Borrowing shall be
irrevocable and binding on the Borrower. Each Notice of Borrowing shall be
effective upon delivery of a copy thereof to the Primary Liquidity Provider's
New York branch (with a copy to the Lending Office) at the address specified
pursuant to the terms of Section 7.02 hereof.

         (f)      Upon the making of any Advance requested pursuant to a Notice
of Borrowing in accordance with the Borrower's payment instructions, the Primary
Liquidity Provider shall be fully discharged of its obligation hereunder with
respect to such Notice of Borrowing, and the Primary 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 (including the
Trustee or any Class G Certificateholder). If the Primary 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 Section 2.02(e), the Primary 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(c) or 2.02(d) to fund the Primary Cash
Collateral Account, the Primary Liquidity Provider shall have no interest in or
rights to the Primary Cash Collateral Account, such Advance or any other amounts
from time to time on deposit in the Primary 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 3.06(e) or
3.06(f) of the Intercreditor Agreement and provided further, that the foregoing
shall not affect or impair the rights of the Primary Liquidity Provider to
provide written instructions with respect to the investment and reinvestment of
amounts in the Primary Cash Collateral Account to the extent provided in Section
2.02(b) 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 Primary 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 Primary Liquidity
Provider the fees set forth in the 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 Capped Interest Rate or the Pool
Balance of the Class G Certificates (including upon any Policy Provider Election
with respect to a Series G Equipment Note) 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 Primary Liquidity
Provider, the Policy Provider and Delta 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.


                                       10
<PAGE>

         (b)      Termination. Upon the making of any Provider Advance or the
making or conversion to a Final Advance hereunder or the occurrence of the
Termination Date, the obligation of the Primary 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 Primary Liquidity
Provider (which notice and demand are hereby waived by the Borrower), to pay, or
to cause to be paid, to the Primary Liquidity Provider on each date on which the
Primary 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 in the amounts and on the dates determined as
provided in Section 3.07; provided that if (i) the Primary 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 Primary Liquidity Facility shall become a Downgraded Facility at
any time when unreimbursed Interest Advances have reduced the Maximum Available
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 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 Primary Liquidity Provider in accordance with Section 2.06 and for the
purposes of Section 2.06(b)). The Borrower and the Primary 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 Primary Liquidity Provider. For the
avoidance of doubt, interest payable on an Interest Advance or the Final Advance
shall not be regarded as overdue unless such interest is not paid when due under
Section 3.07.

         Section 2.06. Repayments of Provider Advances. (a) Amounts advanced
hereunder in respect of a Provider Advance shall be deposited in the Primary
Cash Collateral Account and invested and withdrawn from the Primary Cash
Collateral Account as set forth in Sections 3.06(c)(i), 3.06(d), 3.06(e) and
3.06(f) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09, the
Borrower agrees to pay to the Primary 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, in the amounts determined as provided in Section 3.07;
provided, however, that amounts in respect of a Provider Advance withdrawn from
the Primary Cash Collateral Account for the purpose of paying interest on the
Class G Certificates in accordance with Section 3.06(f) of the Intercreditor
Agreement (the amount of any such withdrawal being, an "APPLIED DOWNGRADE
ADVANCE" or 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 and the
dates on which such interest is payable; provided further, however, that if,
following the making of a Provider Advance, the Primary Liquidity Provider
delivers a Termination Notice to the Borrower and the Policy Provider pursuant
to Section 6.01, 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


                                       11
<PAGE>

thereon and the dates on which such interest is payable. Subject to Sections
2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the
Primary Cash Collateral Account on account of a reduction in the Required
Amount, the Borrower shall repay to the Primary 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.

         (b)      At any time when an Applied Provider Advance (or any portion
thereof) is outstanding, upon the deposit in the Primary Cash Collateral Account
of any amount pursuant to clause "third" of Section 2.04(b) of the Intercreditor
Agreement, clause "third" of Section 3.02 of the Intercreditor Agreement or
clause "fourth" of Section 3.03 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 Primary Liquidity Facility
in replacement of this Agreement in accordance with Section 3.06(e) of the
Intercreditor Agreement, as provided in Section 3.06(f)(iii) of the
Intercreditor Agreement, amounts remaining on deposit in the Primary Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Primary Liquidity Provider,
but only to the extent such amounts are necessary to repay in full to the
Primary Liquidity Provider all amounts owing to it hereunder.

         Section 2.07. Payments to the Primary Liquidity Provider Under the
Intercreditor Agreement. In order to provide for payment or repayment to the
Primary 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 Primary Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.06(f) of the Intercreditor Agreement), shall be paid to
the Primary Liquidity Provider in accordance with the terms thereof (but, for
the avoidance of doubt, without duplication of or increase in any amounts
payable hereunder). Amounts so paid to, and not required to be returned by, the
Primary Liquidity Provider shall be applied by the Primary Liquidity Provider in
the order of priority required by the applicable provisions of Articles II and
III of the Intercreditor Agreement and shall discharge in full the corresponding
obligations of the Borrower hereunder.

         Section 2.08. Book Entries. The Primary 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 Primary
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 and other payments under
the Operative Agreements, including payment under Section 4.02 of the
Participation Agreements and payments under Section 2.14 of the Indentures, 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 Primary 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 Primary 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 3.06(f) of the Intercreditor
Agreement.

                                  ARTICLE III

                           OBLIGATIONS OF THE BORROWER

         Section 3.01. Increased Costs. If as a result of any Regulatory Change
there shall be any increase by an amount reasonably deemed by the Primary
Liquidity Provider to be material in the actual cost to the Primary Liquidity
Provider of making, funding or maintaining any Advances or its obligation to
make any such Advances or there shall be any reduction by an amount reasonably
deemed by the Primary Liquidity Provider to be material in the amount receivable
by the Primary Liquidity Provider under this Agreement or the Intercreditor
Agreement in respect thereof, and in case of either such an increase or
reduction, such event does not arise from the gross negligence or willful
misconduct of the Primary Liquidity Provider, from its breach of any of its
representations, warranties, covenants or agreements contained herein or in the
Intercreditor Agreement or from its failure to comply with any such Regulatory
Change (any such increase or reduction being referred to herein as an "INCREASED
COST"), then the Borrower shall from time to time pay to the Primary Liquidity
Provider an amount equal to such Increased Cost within 15 Business Days after
delivery to the Borrower and Delta of a certificate of an officer of the Primary
Liquidity Provider describing in reasonable detail the event by reason of which
it claims such Increased Cost and the basis for the determination of the amount
of such Increased Cost; provided that, the Borrower shall be obligated to pay
amounts only with respect to any Increased Costs accruing from the date 45 days
prior to the date of delivery of such certificate. Such certificate, in the
absence of manifest error, shall be considered prima facie evidence of the
amount of the Increased Costs for purposes of this Agreement; provided that any
determinations and allocations by the Primary Liquidity Provider of the effect
of any Regulatory Change on the costs of maintaining the Advances are made on a
reasonable basis. The Primary Liquidity Provider shall not be entitled to assert
any claim under this Section 3.01 in respect of or attributable to Taxes. The
Primary Liquidity Provider will notify the Borrower and Delta as promptly as
practicable of any event occurring after the date of this Agreement that will
entitle the Primary Liquidity Provider to compensation under this Section 3.01,
which notice shall describe in reasonable detail the calculation of amounts owed
under this


                                       13

Section 3.01. The Primary Liquidity Provider agrees to investigate all
commercially reasonable alternatives for reducing any Increased Costs and to use
all commercially reasonable efforts (consistent with applicable legal and
regulatory restrictions) to avoid or minimize, to the greatest extent possible,
any claim in respect of Increased Costs, including, without limitation, by
designating a different Lending Office, if such designation or other action
would avoid the need for, or reduce the amount of, any such claim; provided that
the foregoing shall not obligate the Primary Liquidity Provider to take any
action that would, in its reasonable judgment, cause the Primary Liquidity
Provider to incur any material loss or cost, unless the Borrower or Delta agrees
to reimburse the Primary Liquidity Provider therefor. If no such designation or
other action is effected, or, if effected, fails to avoid the need for any claim
in respect of Increased Costs, Delta may arrange for a Replacement Primary
Liquidity Facility in accordance with Section 3.06(e) of the Intercreditor
Agreement.

         Notwithstanding the foregoing provisions, in no event shall the
Borrower be required to make payments under this Section 3.01: (a) in respect of
any Regulatory Change proposed by any applicable governmental authority
(including any branch of a legislature), central bank or comparable agency of
the United States or the Primary Liquidity Provider's jurisdiction of
organization and pending as of the date of this Agreement (it being agreed that
the consultative paper issued by the Basel Committee on Banking Supervision
entitled "The New Basel Capital Accord", dated January 2001, shall not be
considered to have been proposed or pending as of the date of this Agreement);
(b) if a claim hereunder in respect of an Increased Cost arises through
circumstances peculiar to the Primary Liquidity Provider and that do not affect
similarly organized commercial banking institutions in the same jurisdiction
generally that are in compliance with the law, rule, regulation or
interpretation giving rise to the Regulatory Change relating to such Increased
Cost; (c) if the Primary Liquidity Provider shall fail to comply with its
obligations under this Section 3.01; or (d) if the Primary Liquidity Provider is
not also seeking payment for similar increased costs in other similarly situated
transactions.

         Section 3.02. [Intentionally omitted.]

         Section 3.03. Withholding Taxes. (a) All payments made by the Borrower
under this Agreement shall be made without deduction or withholding for or on
account of any Taxes, unless such deduction or withholding is required by law.
If any Taxes are so required to be withheld or deducted from any amounts payable
to the Primary Liquidity Provider under this Agreement, the Borrower shall pay
to the relevant authorities the full amount so required to be deducted or
withheld and, if such Taxes are Covered Taxes, pay to the Primary Liquidity
Provider such additional amounts as shall be necessary to ensure that the net
amount actually received by the Primary Liquidity Provider (after deduction or
withholding of all Covered Taxes) shall be equal to the full amount that would
have been received by the Primary Liquidity Provider had no withholding or
deduction of Covered Taxes been required. The Primary 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 such additional
amounts that may thereafter accrue and would not, in the reasonable judgment of
the Primary Liquidity Provider, be otherwise materially disadvantageous to the
Primary Liquidity Provider. If the Primary Liquidity Provider receives a refund
of, or realizes a net Tax benefit not otherwise available to it as a result of,
any Taxes for which additional amounts were paid by the Borrower pursuant to


                                       14
<PAGE>

this Section 3.03, the Primary Liquidity Provider shall pay to the Borrower (for
deposit into the Collection Account) the amount of such refund (and any interest
thereon) or net benefit.

         The Primary Liquidity Provider will (i) provide (on its behalf and on
behalf of any participant holding a Participation pursuant to Section 7.08) to
the Borrower (x) on or prior to the Effective Date two valid completed and
executed copies of Internal Revenue Service Form W8-BEN or W8-EC1 (whichever is
applicable), including thereon a valid U.S. taxpayer identification number (or,
with respect to any such participant, such other form or documentation as may be
applicable) covering all amounts receivable by it in connection with the
transactions contemplated by the Operative Agreements and (y) thereafter from
time to time such additional forms or documentation as may be necessary to
establish an available exemption from withholding of United States Tax on
payments hereunder so that such forms or documentation are effective for all
periods during which it is the Primary Liquidity Provider and (ii) provide
timely notice to the Borrower if any such form or documentation is or becomes
inaccurate. The Primary Liquidity Provider shall deliver to the Borrower such
other forms or documents as may be reasonably requested by the Borrower or
required by applicable law to establish that payments hereunder are exempt from
or entitled to a reduced rate of Covered Taxes.

         (b)      All payments (including, without limitation, Advances) made by
the Primary 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 Primary 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 additional amounts payable 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 under this Section 3.03(b), the Primary 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.

         If any exemption from, or reduction in the rate of, any Taxes required
to be borne by the Primary Liquidity Provider under this Section 3.03(b) is
reasonably available to the Borrower without providing any information regarding
the holders or beneficial owners of the Certificates, the Borrower shall deliver
the Primary Liquidity Provider such form or forms and such other evidence of the
eligibility of the Borrower for such exemption or reductions (but without any
requirement to provide any information regarding the holders or beneficial
owners of the Certificates) as the Primary Liquidity Provider may reasonably
identify to the Borrower as being required as a condition to exemption from, or
reduction in the rate of, such Taxes.

         Section 3.04. Payments. The Borrower shall make or cause to be made
each payment to the Primary Liquidity Provider under this Agreement so as to
cause the same to be received by the Primary 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 Dollars, to the Primary Liquidity Provider in immediately
available funds, by wire transfer to Deutsche Bank Trust Co. Americas, New York,

Baden-Wurttemberg, Stuttgart; Account No. 04-095-107; Swift Code: SOLADEST;
Reference: 4921 Loan Administration, Delta EETC 2003-1, or such other account as
the Primary Liquidity Provider shall notify the Borrower.

         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 Sections 2.07 and 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 Primary Cash
Collateral Account to pay interest on the Class G 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 Primary 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) that 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 the interest rate per annum
for each day equal to the Applicable Liquidity Rate (as defined below) for such
Advance or such other amount, as the case may be, 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 to the maximum extent permitted by applicable
law 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 absolute
amount of interest that would have accrued (without additional interest thereon)
if such otherwise applicable interest rate as set forth in this Section 3.07 had
at all relevant times been in effect. Nothing contained in this Section 3.07
shall require the Borrower to pay any amount under this Section 3.07 other than
as specified in Section 2.09.

         (b)      Except as provided in Section 3.07(e), each Advance will be
either a Base Rate Advance or a LIBOR Advance as provided in this Section 3.07.
Each such Advance will be a Base Rate Advance for the period from the date of
its borrowing to (but excluding) the third


                                       16
<PAGE>

London/Stuttgart Business Day following the Primary Liquidity Provider's receipt
of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be 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 outstanding Unapplied Provider Advance shall bear
interest in an amount equal to the Investment Earnings on amounts on deposit in
the Primary Cash Collateral Account from time to time, payable in arrears on
each Regular Distribution Date. A Final Advance resulting from the conversion of
any Advance or an Unapplied Provider Advance pursuant to Section 6.01 shall
always be a LIBOR Advance. Each Applied Provider Advance shall always be a LIBOR
Advance.

         (f)      Each amount not paid 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% per annum 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. Subject to Section 5.02, from
time to time and subject to the successor Borrower's meeting the eligibility
requirements set forth in Section 6.09 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 (a "NOTICE OF REPLACEMENT SUBORDINATION AGENT") delivered to
the Primary Liquidity Provider and the Policy Provider by the then Borrower, the
successor Borrower designated therein shall become the Borrower for all purposes
hereunder.

         Section 3.09. Funding Loss Indemnification. The Borrower shall pay to
the Primary Liquidity Provider, upon the request of the Primary Liquidity
Provider, such amount or amounts as shall be sufficient (in the reasonable
opinion of the Primary 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 Primary Liquidity Provider to fund or maintain any
LIBOR Advance (but excluding loss of the Applicable Margin or anticipated
profits) incurred as a result of:


                                       17
<PAGE>

                  (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 law, rule or regulation applicable to or binding
on the Primary Liquidity Provider, 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 Primary Liquidity Provider 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 Primary Liquidity Provider
to maintain or fund its LIBOR Advances, then upon notice to the Borrower, the
Policy Provider and Delta by the Primary Liquidity Provider, the outstanding
principal amount of the LIBOR Advances shall be converted to Base Rate Advances
(a) immediately upon demand of the Primary Liquidity Provider, if such change or
compliance with such request, in the reasonable judgment of the Primary
Liquidity Provider, requires immediate conversion; or (b) at the expiration of
the last Interest Period to expire before the effective date of any such change
or request. The Primary Liquidity Provider will notify the Borrower and Delta as
promptly as practicable of any event that will lead to the conversion of LIBOR
Advances to Base Rate Advances under this Section 3.10. The Primary Liquidity
Provider agrees to investigate all commercially reasonable alternatives for
avoiding the need for such conversion, including, without limitation,
designating a different Lending Office, if such designation or other action
would avoid the need to convert such LIBOR Advances to Base Rate Advances;
provided that the foregoing shall not obligate the Primary Liquidity Provider to
take any action that would, in its reasonable judgment, cause the Primary
Liquidity Provider to incur any material loss or cost, unless the Borrower or
Delta agrees to reimburse the Primary Liquidity Provider therefor. If no such
designation or other action is effected, or, if effected, fails to avoid the
need for conversion of the LIBOR Advances to Base Rate Advances, Delta may
arrange for a Replacement Primary Liquidity Facility in accordance with Section
3.06(e) of the Intercreditor Agreement.

                  over the internet) and (y) Delta agrees to allow the Primary
                  Liquidity Provider to discuss the transactions contemplated by
                  the Operative Agreements with officers and employees of Delta.

<PAGE>

         Provider, certifying that all conditions precedent specified in this
         Section 4.01 have been satisfied or waived by the Primary Liquidity
         Provider.

         Section 4.02. Conditions Precedent to Borrowing. The obligation of the

                                   ARTICLE V

Advance shall remain unpaid or the Primary Liquidity Provider shall have any
Maximum Commitment hereunder or the Borrower shall have any obligation to pay
any amount to the Primary Liquidity Provider hereunder, the Borrower will,
unless the Primary Liquidity Provider shall otherwise consent in writing:

                  (a)      Performance of This and Other Agreements. Punctually
         pay or cause to be paid all amounts payable by it under this Agreement,
         the Intercreditor Agreement and the Fee Letter and observe and perform
         in all material respects the conditions, covenants and requirements
         applicable to it contained in this Agreement, the Intercreditor
         Agreement and the Fee Letter.

                  (b)      Reporting Requirements. Furnish to the Primary
         Liquidity Provider with reasonable promptness, such other information
         and data with respect to the transactions contemplated by the Operative
         Agreements as from time to time may be reasonably requested by the
         Primary Liquidity Provider; and permit the Primary Liquidity Provider,
         upon reasonable notice, to inspect the Borrower's books and records
         with respect to such transactions and to meet with officers and
         employees of the Borrower to discuss such transactions.

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

         Section 5.02. Negative Covenants of the Borrower. Subject to the first
and fourth paragraphs of Section 7.01(a) of the Intercreditor Agreement and
Section 7.01(b) of the Intercreditor Agreement, so long as any Advance shall
remain unpaid or the Primary Liquidity Provider shall have any Maximum
Commitment hereunder or the Borrower shall have any obligation to pay any amount
to the Primary 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 Primary Liquidity Provider, which consent shall not be
unreasonably withheld or delayed.

                           LIQUIDITY EVENTS OF DEFAULT

         Section 6.01. Liquidity Events of Default. If (a) any Liquidity Event
of Default has occurred and is continuing and (b) there is a Performing Note
Deficiency, the Primary Liquidity Provider may, in its discretion, deliver to

said Sections or in such Fee Letter)), that may be imposed on or incurred by
such 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 Fee
Letter, the Intercreditor Agreement or any Participation 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 to the extent such Expense is (i) attributable to the
negligence or willful misconduct of such Liquidity Indemnitee or any other
Liquidity Indemnitee, (ii) an ordinary and usual operating overhead expense,
(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 Fee Letter or any other Operative Agreement to which it is a
party or (iv) otherwise excluded from the indemnification provisions contained

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 Primary 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 Primary Liquidity Provider, and the Primary Liquidity Provider
shall be liable to the Borrower, to the extent of any damages suffered by the
Borrower that were the result of (A) the Primary Liquidity Provider's willful
misconduct or gross negligence in determining whether documents presented
hereunder comply with the terms hereof or (B) any breach by the Primary
Liquidity Provider of any of the terms of this Agreement or the Intercreditor
Agreement, including, but not limited to, the Primary Liquidity Provider's
failure to make lawful payment hereunder after the delivery to it by the
Borrower of a Notice of Borrowing complying with the terms and conditions
hereof.

         (b)      Neither the Primary Liquidity Provider nor any of its
officers, employees or directors or affiliates shall be liable or responsible 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


                                       23
<PAGE>

misconduct or negligence (in which event the extent of the Primary 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. Certain Costs and Expenses. The Borrower agrees promptly

Default occurs, all out-of-pocket expenses incurred by the Primary Liquidity
Provider, including reasonable fees and disbursements of counsel, in connection
with such Liquidity Event of Default and any collection, bankruptcy, insolvency
and other enforcement proceedings in connection therewith. In addition, the
Borrower shall pay any and all recording, stamp and other similar taxes and fees
payable or determined to be payable in the United States 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 Primary Liquidity

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 Primary
Liquidity Provider and their respective successors and permitted assigns, except
that neither the Primary 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, pledge or otherwise transfer its rights or
obligations hereunder or any interest herein, subject to the Primary Liquidity
Provider's right to grant Participations pursuant to Section 7.08(b).

         (b)      The Primary Liquidity Provider agrees that it will not grant
any participation (including, without limitation, a "RISK PARTICIPATION") (any
such participation, a "PARTICIPATION") in or to all or a portion of its rights
and obligations hereunder or under the other Operative Agreements, unless all of
the following conditions are satisfied: (i) such Participation is to a Permitted
Transferee, (ii) such Participation is made in accordance with all applicable
laws, including, without limitation, the Securities Act of 1933, as amended, the
Trust Indenture Act of 1939, as amended, and any other applicable laws relating

made under circumstances that require registration under the Securities Act of
1933, as amended, or qualification of any indenture under the Trust Indenture
Act of 1939, as amended. Notwithstanding any such Participation, the Primary
Liquidity Provider agrees that (1) the Primary Liquidity Provider's obligations
under the Operative Agreements shall remain unchanged, and such participant
shall have no rights or benefits as against Delta or the Borrower or under any
Operative Agreement, (2) the Primary Liquidity Provider shall remain solely
responsible to the other parties to the Operative Agreements for the performance
of such obligations, (3) the Primary Liquidity Provider shall remain the maker
of any Advances, and the other parties to the Operative Agreements shall
continue to deal solely and directly with the Primary Liquidity Provider in
connection with the Advances and the Primary Liquidity Provider's rights and
obligations under the Operative Agreements, (4) the Primary Liquidity Provider
shall be solely responsible for any withholding Taxes or any filing or reporting
requirements relating to such Participation and shall hold the Borrower and
Delta and


                                       24
<PAGE>

their respective successors, permitted assigns, affiliates, agents and servants
harmless against the same and (5) neither Delta nor the Borrower shall be
required to pay to the Primary Liquidity Provider any amount under Section 3.01
or Section 3.03 greater than it would have been required to pay had there not
been any grant of a Participation by the Primary Liquidity Provider. The Primary
Liquidity Provider may, in connection with any Participation or proposed
Participation pursuant to this Section 7.08(b), disclose to the participant or
proposed participant any information relating to the Operative Agreements or to
the parties thereto furnished to the Primary Liquidity Provider thereunder or in
connection therewith and permitted to be disclosed by the Primary Liquidity
Provider; provided, however, that prior to any such disclosure, the participant
or proposed participant shall agree in writing for the express benefit of the
Borrower and Delta to preserve the confidentiality of any confidential
information included therein (subject to customary exceptions).

         (c)      Notwithstanding the other provisions of this Section 7.08, the
Primary Liquidity Provider may assign and pledge all or any portion of the
Advances owing to it to any Federal Reserve Bank or the United States Treasury
as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank, provided that any payment in respect of such assigned Advances made by the
Borrower to the Primary Liquidity Provider in accordance with the terms of this
Agreement shall satisfy the Borrower's obligations hereunder in respect of such
assigned Advance to the extent of such payment. No such assignment shall release
the Primary Liquidity Provider from its obligations hereunder.

         Section 7.09. Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         Section 7.10. Governing Law. THIS AGREEMENT HAS BEEN DELIVERED IN THE
STATE OF NEW YORK AND THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE, AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

         Section 7.11. Submission to Jurisdiction; Waiver of Jury Trial; Waiver
of Immunity. (a) Each of the parties hereto, to the extent it may do so under
applicable law, for purposes hereof hereby (i) irrevocably submits itself to the
non-exclusive jurisdiction of the courts of the State of New York sitting in the
City of New York and to the non-exclusive jurisdiction of the United States

proceeding is brought in an inconvenient forum, that the venue of the suit,
action or proceeding is improper or


                                       25
<PAGE>

that this Agreement or the subject matter hereof or any of the transactions
contemplated hereby may not be enforced in or by such courts.

         (b)      THE BORROWER AND THE PRIMARY 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

counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN

SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

         (c)      The Primary Liquidity Provider hereby waives any immunity it
may have from the jurisdiction of the courts of the United States or of any
state thereof and waives any immunity any of its properties located in the
United States may have from attachment or execution upon a judgment entered by
any such court under the United States Foreign Sovereign Immunities Act of 1976
or any similar successor legislation.

number of counterparts (and each party shall not be required to execute the same
counterpart). Each counterpart of this Agreement including a signature page or
pages executed by each of the parties hereto shall be an original counterpart of
this Agreement, but all of such counterparts together shall constitute one

         Section 7.13. Entirety. This Agreement and the Intercreditor Agreement
constitute the entire agreement of the parties hereto with respect to the
subject matter hereof and supersede all prior understandings and agreements of
such parties.
