ARTICLE II

AMOUNT AND TERMS OF THE COMMITMENT

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

          Section
2.02 Making of Advances. (a) Each Interest Advance shall be made by the
Liquidity Provider upon delivery to the Liquidity 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 B Certificates at
the Stated Interest Rate therefor in accordance with Section 3.05(a) and
3.05(b) of the Intercreditor Agreement. Each Interest Advance made hereunder
shall automatically reduce the Maximum Available 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 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. 

8

                    (b)
A Downgrade Advance shall be made by the Liquidity Provider upon the occurrence
of a Downgrade Event (as provided for in Section 3.05(c) of the Intercreditor
Agreement) unless a Replacement Liquidity Facility to replace this Agreement
shall have been previously delivered to the Borrower in accordance with said
Section 3.05(c), upon delivery to the Liquidity 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 Class B Cash
Collateral Account in accordance with Sections 3.05(c) and 3.05(f) of the
Intercreditor Agreement. 

                    (c)
A Final Advance shall be made by the Liquidity Provider following the receipt
by the Borrower of a Termination Notice from the Liquidity Provider pursuant to
Section 6.01 upon delivery to the Liquidity Provider of a written and completed
Notice of Borrowing in substantially the form of Annex IV, 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 Class B Cash Collateral
Account (in accordance with Sections 3.05(f) and 3.05(i) of the Intercreditor
Agreement). 

                    (d)
A Special Termination Advance shall be made in a single Borrowing upon the
receipt by the Borrower of a Special Termination Notice from the Liquidity
Provider pursuant to Section 6.01(b), by delivery to the Liquidity Provider of
a written and completed Notice of Borrowing in substantially the form of Annex
IV, 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 Class
B Cash Collateral Account (in accordance with Section 3.5(f) and Section 3.5(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(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 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 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 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 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 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

9

delivery of a
copy thereof to the Liquidity Provider’s New York branch at the address
specified in 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 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 (including the Trustee or any
Class B Certificateholder). 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(c) or 2.02(d) 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 3.05(e) or 3.05(f) of the Intercreditor
Agreement. By paying to the Borrower proceeds of Advances requested by the
Borrower in accordance with the provisions of this Agreement, the Liquidity
Provider makes no representation as to, and assumes no responsibility for, the
correctness or sufficiency for any purpose of the amount of the Advances so
made and requested. 

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

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

                    (b)
Termination. Upon the making of any Provider Advance, Special
Termination 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, the Special Termination Advance 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 

10

Liquidity
Provider (a) on each date on which the Liquidity Provider shall make an
Interest Advance, the Special Termination Advance or the Final Advance, an
amount equal to 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 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 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 Liquidity Provider in
accordance with Section 2.06 and for the purposes of Section 2.06(b)) provided,
further, that amounts in respect of a Special Termination Advance
withdrawn from the Class B Cash Collateral Account for the purpose of paying
interest on the Class B Certificates in accordance with Section 3.05(f) of the
Intercreditor Agreement (the amount of any such withdrawal being an “Applied Special Termination 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 provided, further, that if,
following the making of a Special Termination Advance, the Liquidity Provider
delivers a Termination Notice to the Borrower pursuant to Section 6.01(a), such
Special Termination Advance shall thereafter be treated as a Final Advance
under this Agreement for purposes of determining the Applicable Liquidity Rate
for interest payable thereon and the obligation for repayment thereof. The
Borrower and the Liquidity Provider agree that the repayment in full of each
Interest Advance, Special Termination 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. For the avoidance of doubt,
interest payable on an Interest Advance, Special Termination 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 Class B Cash Collateral
Account and invested and withdrawn from the Class B Cash Collateral Account as
set forth in Sections 3.05(c), 3.05(d), 3.05(e) and 3.05(f) of the Intercreditor
Agreement. Subject to Sections 2.07 and 2.09, 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, in the amounts determined as
provided in Section 3.07; provided, however, that amounts in respect of a
Provider Advance withdrawn from the Class B Cash Collateral Account for the
purpose of paying interest on the Class B Certificates in accordance with
Section 3.05(f) of the Intercreditor Agreement (the amount of any such
withdrawal being (y) in the case of a Downgrade Advance, an “Applied Downgrade Advance”
and 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 Liquidity Provider delivers a
Termination Notice to the Borrower pursuant to Section 6.01, such Provider
Advance shall thereafter be treated as a Final Advance under this Agreement for

11

purposes of
determining the Applicable Liquidity Rate for interest payable 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 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. 

                    (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 of any
amount pursuant to clause “fourth” of Section 3.02 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 3.05(e) of the Intercreditor Agreement, as
provided in Section 3.05(f) 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, but only to the extent such amounts are necessary to
repay in full to the Liquidity Provider all amounts owing to it hereunder. 

          Section
2.07 Payments to the Liquidity Provider Under the Intercreditor Agreement.
In order to provide for payment or repayment to the Liquidity Provider of any
amounts hereunder, the Intercreditor Agreement provides that amounts available
and referred to in Articles II and III of the Intercreditor Agreement, to the
extent payable to the Liquidity Provider pursuant to the terms of the
Intercreditor Agreement (including, without limitation, Section 3.05(f) of the
Intercreditor Agreement), shall be paid to the 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 the Liquidity
Provider shall be applied by the 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 Liquidity Provider shall maintain in accordance
with its usual practice an account or accounts evidencing the indebtedness of
the Borrower resulting from Advances made from time to time and the amounts of
principal and interest payable hereunder and paid from time to time in respect
thereof; provided; however, that the failure by the Liquidity Provider to
maintain such account or accounts shall not affect the obligations of the
Borrower in respect of Advances. 

          Section
2.09 Payments from Available Funds Only. All payments to be made by the
Borrower under this Agreement shall be made only from the amounts that constitute
Scheduled Payments, Special Payments and other payments under the Operative
Agreements, including

12

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 Liquidity
Provider agrees that it will look solely to such amounts to the extent
available for distribution to it as provided in the Intercreditor Agreement and
this Agreement and that the Borrower, in its individual capacity, is not
personally liable to it for any amounts payable or liability under this
Agreement except as expressly provided in this Agreement, the Intercreditor
Agreement or any Participation Agreement. Amounts on deposit in the Class B
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 3.05(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 Liquidity Provider
to be material in the actual cost to the 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 Liquidity
Provider to be material in the amount receivable by the 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 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
Liquidity Provider an amount equal to such Increased Cost within 10 Business
Days after delivery to the Borrower and Delta of a certificate of an officer of
the 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
90 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 Liquidity Provider of the effect of any
Regulatory Change on the costs of maintaining the Advances are made on a
reasonable basis. The Liquidity Provider shall not be entitled to assert any
claim under this Section 3.01 in respect of or attributable to Excluded Taxes.
The 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
Liquidity Provider to compensation under this Section 3.01. The Liquidity
Provider agrees to investigate all commercially reasonable alternatives for
reducing any Increased Costs and to use all commercially reasonable efforts 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 Liquidity Provider to take any action that would, in its
reasonable

13

judgment,
cause the Liquidity Provider to take any action that is not materially
consistent with its internal policies or is otherwise materially
disadvantageous to the Liquidity Provider or that would cause the Liquidity
Provider to incur any material loss or cost, unless the Borrower or Delta
agrees to reimburse or indemnify the 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 Liquidity Facility in accordance with Section 3.05(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
Liquidity Provider’s jurisdiction of organization and pending as of the date of
this Agreement (it being agreed that the Consultative Document 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 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 Liquidity Provider shall fail to comply with
its obligations under this Section 3.01 or (d) if the Liquidity Provider is not
also seeking payment for similar increased costs in other similarly situated
transactions related to the airline industry. 

          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 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 Liquidity Provider such
additional amounts as shall be necessary to ensure that the net amount actually
received by the Liquidity Provider (after deduction or withholding of all
Covered Taxes) shall be equal to the full amount that would have been received
by the Liquidity Provider had no withholding or deduction of Covered Taxes been
required. The Liquidity Provider agrees to use reasonable efforts (consistent
with applicable legal and regulatory restrictions) to change the jurisdiction
of its Lending Office if making such change would avoid the need for, or reduce
the amount of, any such additional amounts that may thereafter accrue and would
not, in the reasonable judgment of the Liquidity Provider, be otherwise
materially disadvantageous to the Liquidity Provider. If the 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 this Section 3.03, the 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
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 

14

W8-ECI
(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 Liquidity Provider and (ii)
provide timely notice to the Borrower if any such form or documentation is or
becomes inaccurate. The 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 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
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
hereunder, the Liquidity Provider shall furnish to the Borrower the original or
a certified copy of (or other documentary evidence of) the payment of the Taxes
applicable to such payment. 

          If
any exemption from, or reduction in the rate of, any Taxes required to be borne
by the 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 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 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 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
Dollars, to the Liquidity Provider in immediately available funds, by wire
transfer to the account of Landesbank Hessen Thüringen, at Citibank N.A., ABA
No. 021000089 Account Name: Landesbank Hessen Thüringen, Account No. 10920118;
or to such other U.S. bank account as the Liquidity Provider may from time to
time direct the Subordination Agent. 

          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 

15

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 or Applied Special Termination
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 or Applied Special
Termination 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) 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. 

                    (b)
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 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 a
Provider Advance shall always be a LIBOR Advance unless the Borrower elects
otherwise. 

                    (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).

16

                    (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

                    (e)
[Reserved.] 

                    (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 2.0% 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 VI (a “Notice
of Replacement Subordination Agent”) delivered to the Liquidity
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
Liquidity Provider, upon the request of the Liquidity Provider, such amount or
amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider)
to compensate it for any loss, cost or expense incurred by reason of the
liquidation or redeployment of deposits or other funds acquired by the
Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of
the Applicable Margin or 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 law, rule or regulation applicable to or binding on the
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
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 Liquidity Provider to maintain or fund
its LIBOR Advances, then upon notice to the Borrower and Delta 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 reasonable 

17

judgment of
the 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 Liquidity Provider will notify the Borrower and Delta as
promptly as practicable of any event that will or to its knowledge is
reasonably likely to lead to the conversion of LIBOR Advances to Base Rate
Advances under this Section 3.10, provided that a failure by the Liquidity
Provider to notify the Borrower or Delta of an event that is reasonably likely
to lead to such a conversion prior to the time that it is determined that such
event will lead to such a conversion shall not prejudice the rights of the
Liquidity Provider under this Section 3.10. The 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 Liquidity Provider to take any action that would, in its
reasonable judgment, cause the Liquidity Provider to incur any material loss or
cost, unless the Borrower or Delta agrees to reimburse or indemnify the
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 Liquidity
Facility in accordance with Section 3.05(e) of the Intercreditor Agreement.

ARTICLE II

TRUST ACCOUNTS; CONTROLLING PARTY

                    Section
2.01. Agreement to Terms of Subordination; Payments from Monies Received Only.
(a) Each Trustee hereby (i) acknowledges and agrees to the terms of
subordination and distribution set forth in this Agreement in respect of each
Class of Certificates and (ii) agrees to enforce such provisions and cause all
payments in respect of the Equipment Notes held by the Subordination Agent and
the Liquidity Facilities to be applied in accordance with the terms of this
Agreement. In addition, each Trustee hereby agrees to cause the Equipment Notes
purchased by the related Trust to be registered in the name of the
Subordination Agent or its nominee, as agent and trustee for such Trustee, to
be held in trust by the Subordination Agent solely for the purpose of
facilitating the enforcement of the subordination and other provisions of this
Agreement.  

                    (b)
Except as otherwise expressly provided in the next succeeding sentence of this
Section 2.01(b), all payments to be made by the Subordination Agent hereunder
shall be made only from amounts received by it that constitute Scheduled Payments,
Special Payments and other payments under the Operative Agreements, including
payments under Section 4.02 of the Participation Agreements and Section 2.14 of
the Indentures, and only to the extent that the Subordination Agent shall have
received sufficient income or proceeds therefrom to enable it to make such
payments in accordance with the terms hereof. Each of the Trustees and the
Subordination Agent hereby agrees, and each Certificateholder, by its
acceptance of a Certificate, and each Liquidity Provider, by entering into the
Liquidity Facility to which it is a party, has agreed, to look solely to such
amounts to the extent available for distribution to it as provided in this
Agreement, the relevant Deposits or the applicable Trust Agreement, as the case
may be, and that none of the Trustees, Loan Trustees or the Subordination Agent
is personally liable to any of them for any amounts payable or any liability
arising under this Agreement, any Trust Agreement, any Liquidity Facility or
such Certificate, except (in the case of the Subordination Agent) as expressly
provided herein or (in the case of the Trustees) as expressly provided herein
and in each Trust Agreement or (in the case of the Loan Trustees) as expressly
provided in any Operative Agreement. 

22

                    (c)
Notwithstanding anything to the contrary in this Agreement and in the other
Operative Agreements, the Certificates do not represent indebtedness of the
related Trust, and references in this Agreement and the Operative Agreements to
accrued interest or principal amounts payable on the Certificates of any Class
are included only for computational purposes. For purposes of such
computations, the Certificates of any Class shall be deemed to be comprised of
interest and principal components, with the principal component deemed to be
the Pool Balance, and the interest component deemed to equal interest accruing
at the Stated Interest Rate for such Class of Certificates from (i) the later
of (1) the date of the issuance thereof and (2) the most recent but preceding
Distribution Date to which such interest was distributed (ii) the applicable
date of determination, such interest to be considered payable in arrears and to
be calculated on the basis of a 360-day year comprised of twelve 30-day months.

                    Section
2.02. Trust Accounts. (a) Upon the execution of this Agreement, the
Subordination Agent shall establish and maintain in its name (i) the Collection
Account as an Eligible Deposit Account, bearing a designation clearly
indicating that the funds deposited therein are held in trust for the benefit
of the Trustees, the Certificateholders and the Liquidity Providers, and (ii)
as a sub-account in the Collection Account, the Special Payments Account as an
Eligible Deposit Account, bearing a designation clearly indicating that the
funds deposited therein are held in trust for the benefit of the Trustees, the
Certificateholders and the Liquidity Providers. The Subordination Agent shall
establish and maintain the Cash Collateral Accounts pursuant to and under the
circumstances set forth in Section 3.05(f). Upon such establishment and
maintenance under Section 3.05(f), the Cash Collateral Accounts shall, together
with the Collection Account, constitute the “Trust Accounts” hereunder. Without
limiting the foregoing, all monies credited to the Trust Accounts shall be, and
shall remain, the property of the relevant Trust(s).

                    (b)
Funds on deposit in the Trust Accounts shall be invested and reinvested by the
Subordination Agent in Eligible Investments selected by Delta or its designated
representative if such investments are reasonably available and have maturities
no later than the earlier of (i) 90 days following the date of such investment
and (ii) the Business Day immediately preceding the Regular Distribution Date
or the date of the related distribution pursuant to Section 2.04, as the case
may be, next following the date of such investment; provided, however, that,
following the making of a Non-Extension Drawing under any Liquidity Facility,
the Subordination Agent shall invest and reinvest the amounts in the applicable
Cash Collateral Account in Eligible Investments pursuant to the written
instructions of the Liquidity Provider funding such Drawing, and provided
further, however, that upon the occurrence and during the continuation of a
Triggering Event, the Subordination Agent shall invest and reinvest such
amounts (other than amounts in the Cash Collateral Accounts as a result of a
Non-Extension Drawing, which shall be governed by the foregoing proviso) in
Eligible Investments in accordance with the written instructions of the
Controlling Party. Unless otherwise expressly provided in this Agreement
(including, without limitation, with respect to Investment Earnings on amounts
on deposit in the Cash Collateral Accounts, Section 3.05(f)), any Investment
Earnings shall be deposited in the Collection Account when received by the
Subordination Agent and shall be applied by the Subordination Agent in the same
manner as the other amounts on deposit in the Collection Account are to be
applied. The Subordination Agent’s reasonable fees and expenses actually
incurred in making such investments and any losses incurred in such investments
shall be charged against the principal amount invested. The Subordination Agent

23

shall not be
liable for any loss resulting from any investment, reinvestment or liquidation
required to be made under this Agreement other than by reason of its willful
misconduct or negligence. Eligible Investments and any other investment
required to be made hereunder shall be held to their maturities except that any
such investment may be sold (without regard to its maturity) by the
Subordination Agent without instructions whenever such sale is necessary to
make a distribution required under this Agreement. Uninvested funds held
hereunder shall not earn or accrue interest. 

                    (c)
The Subordination Agent shall possess all right, title and interest in all
funds on deposit from time to time in the Trust Accounts and in all proceeds
thereof (including all income thereon, except as otherwise expressly provided
herein with respect to Investment Earnings). The Trust Accounts shall be held
in trust by the Subordination Agent under the sole dominion and control of the
Subordination Agent for the benefit of the Trustees, the Certificateholders and
the Liquidity Providers, as the case may be. If, at any time, any of the Trust
Accounts ceases to be an Eligible Deposit Account, the Subordination Agent shall
within 10 Business Days (or such longer period, not to exceed 30 calendar days,
to which a Rating Agency may consent) establish a new Collection Account,
Special Payments Account or Cash Collateral Account, as the case may be, as an
Eligible Deposit Account and shall transfer any cash and/or any investments to
such new Collection Account, Special Payments Account or Cash Collateral
Account, as the case may be. So long as the Subordination Agent is an Eligible
Institution, the Trust Accounts shall be maintained with it as Eligible Deposit
Accounts. 

                    Section
2.03. Deposits to the Collection Account and Special Payments Account.
(a) The Subordination Agent shall, upon receipt thereof, deposit in the
Collection Account all Scheduled Payments received by it (other than any
Scheduled Payment which by the express terms hereof is to be deposited to a
Cash Collateral Account). 

                    (b)
The Subordination Agent shall, on each day when one or more Special Payments
are made to the Subordination Agent as holder of the Equipment Notes, deposit
in the Special Payments Account the aggregate amount of such Special Payments. 

                    (c)
Subject to Section 2.07(h), in the event that a Loan Trustee distributes to the
Subordination Agent pursuant to Section 3.06 or clause “first” of Section 3.03
of any Indenture any amounts payable under clause (a), (b), (c) or (d) of
Section 2.14 of any Indenture, the Subordination Agent shall promptly deposit
such amounts in the Collection Account. Subject to Section 2.07(h), the
Subordination Agent will distribute promptly upon receipt thereof (or in the
case of any such payment, compensation or reimbursement in respect of the
Subordination Agent, will retain) (i) any indemnity payment received by it from
Delta in respect of any Trustee, the Subordination Agent or any Liquidity
Provider (collectively, the “Payees”) and (ii) any compensation or
reimbursement received by it from Delta or any Loan Trustee under any Operative
Agreement in respect of any Payee (including, without limitation, any fees
payable to any Liquidity Provider under Section 2.03 of any Liquidity Facility
or other amounts referred to in clauses (e) or (f) of Section 2.14 of any
Indenture), in any such case directly to the Payee entitled thereto, provided
that if such Payee has previously received from the Collection Account such
payment, compensation or reimbursement, then the Subordination Agent shall
deposit such amount in the Collection Account.

Subordination Agent shall promptly calculate the amount of the proceeds of any
redemption or purchase of any Equipment Note or the amount of any Overdue
Scheduled Payment or the proceeds of Equipment Notes or Collateral, as the case
may be, comprising such Special Payment under the applicable Indenture or
Indentures and shall promptly send to each Trustee a Written Notice of such
amount and the amount allocable to each Trust. Such Written Notice shall also

and the Liquidity Providers hereby agree that, with respect to any Indenture at
any given time, the Loan Trustee thereunder will be directed in taking, or
refraining from taking, any action under such Indenture or with respect to the
Equipment Notes issued thereunder (i) so long as no Indenture Event of Default
has occurred and is continuing thereunder, by a Majority in Interest of
Noteholders of such Equipment Notes (provided that, for so long as the
Subordination Agent is the registered holder of such Equipment Notes, the
Subordination Agent shall act with respect to this clause (i) in accordance
with the directions of the Trustees (in the case of each such Trustee, with
respect to the Equipment Notes issued under such Indenture and held as Trust
Property of such Trust) constituting, in the aggregate, directions with respect

to the holders of the Class B Certificates, the Class C Trustee. For purposes

the Trustees (other than the Controlling Party) irrevocably agree (and the
Certificateholders (other than the Certificateholders represented by the
Controlling Party) shall be deemed to agree by virtue of their purchase of
Certificates) that the Subordination Agent, as record holder of the Equipment
Notes, and subject always to the provisions of Section 2.06(a) and Article
VIII, shall exercise its voting rights in respect of the Equipment Notes so
held by the Subordination Agent as directed by the Controlling Party and any
vote so exercised shall be binding upon the Trustees and all
Certificateholders. 

                    The
Subordination Agent shall give Written Notice to all of the other parties to
this Agreement promptly upon a change in the identity of the Controlling Party.
Each of the parties hereto agrees that it shall not exercise any of the rights
of the Controlling Party at such time as it is not the Controlling Party
hereunder; provided, however, that nothing herein contained shall prevent or
prohibit any Non-Controlling Party from exercising such rights as shall be
specifically granted to such Non-Controlling Party hereunder and under the
other Operative Agreements.

under any Liquidity Facility shall have been drawn (for any reason other than a
Downgrade Drawing, a Special Termination Drawing or a Non-Extension Drawing but
including a Final Drawing, a Special Termination Drawing or a Downgrade Drawing
or a Non-Extension Drawing that has been converted to a Final Drawing under
such Liquidity Facility) and remains unreimbursed, (ii) the date on which the
entire amount of any Downgrade Drawing or Non-Extension Drawing under any
Liquidity Facility shall have become and remain “Applied Downgrade Advances” or
“Applied Non-Extension Advances”, as the case may be, under and as defined in
such Liquidity Facility and (iii) the date on which all Equipment Notes under
all Indentures shall have been Accelerated, the Liquidity Provider(s) with the
greatest amount of unreimbursed Liquidity Obligations owed to it (so long as
such Liquidity Provider has not defaulted in its obligation to make any Drawing
under any Liquidity Facility) shall have the right to elect, by Written Notice
to the Subordination Agent and each of the Trustees, to become the Controlling
Party hereunder with respect to any Indenture at any time from and including
the last day of such 18-month period. 

                    (d)
Notwithstanding the foregoing provisions of clauses (a) through (c) above, if
any holders of the Class B Certificates, Class C Certificates or Additional
Certificates exercise their right under Section 2.07 hereof to purchase
Equipment Notes issued under any Indenture, a Majority in Interest of
Noteholders under such Indenture, instead of the Controlling Party, shall be
entitled to direct the relevant Loan Trustee in taking, or refraining from
taking, any action under such Indenture or with respect to such Equipment
Notes, including exercising remedies thereunder (including Accelerating the
Equipment Notes issued thereunder or foreclosing the 

28

Lien on the
Aircraft securing such Equipment Notes) subject to their agreement to be
subject to the limitations of Sections 4.01(a)(ii) and 4.01(a)(iii) hereof (it
being understood and agreed that any Equipment Notes that continue to be held
by the Subordination Agent shall be voted in accordance with clause (a) above).

                    (e)
The exercise of remedies by the Controlling Party under this Agreement shall be
expressly limited by Section 4.01(a)(ii) and 4.01(a)(iii) hereof. 

                    (f)
The Controlling Party shall not be entitled to require or obligate any
Non-Controlling Party to provide funds necessary to exercise any right or
remedy hereunder. 

                    (g)
Notwithstanding anything contained herein, neither the Controlling Party nor
the Subordination Agent shall be authorized or empowered to do anything that
would cause any Trust to fail to qualify as a “grantor trust” for federal
income tax purposes.

2.07. Equipment Note Buy-Out Rights. (a) If an Equipment Note Buy-Out
Event has occurred and is continuing with respect to any Indenture, then so
long as no Class C Certificateholder or Additional Certificateholder has
elected to exercise its right to purchase Equipment Notes issued under such
Indenture pursuant to this Section 2.07 (upon such election and notification
thereof, the right specified in this Section 2.07(a) shall be suspended and (x)
upon consummation of the purchase pursuant to such election, such right shall
be terminated with respect to such Indenture, or (y) upon failure to consummate
such purchase on the proposed purchase date, such right shall be revived), any
Class B Certificateholder may, upon 15 days’ prior written notice to the
Subordination Agent, each Trustee (and each such Trustee shall promptly provide
such notice to all Certificateholders of its Trust) and the applicable Loan
Trustee, purchase on the third Business Day next following the expiry of such
15-day notice period all, but not less than all, of the Series A Equipment
Notes issued under such Indenture and held by the Subordination Agent for a
purchase price equal to the sum of the aggregate Note Target Price for such
Series A Equipment Notes plus an amount equal to the Excess Liquidity
Obligations in respect of such Indenture accrued as of the date of such
purchase. If prior to the end of such 15-day period, any other holder of the
Class B Certificates notifies the Subordination Agent, each Trustee (and each
such Trustee shall promptly notify all Certificateholders of its Trust,
including the purchasing Class B Certificateholder) and each applicable Loan
Trustee that it wishes to participate in such purchase, then such other
Certificateholder may join with the purchasing Certificateholder to purchase such
Series A Equipment Notes pro rata based on the interest in the Class B Trust
held by each such Certificateholder compared to such interests held by all such
participating Certificateholders. 

                    (b)
If an Equipment Note Buy-Out Event has occurred and is continuing with respect
to any Indenture, then, regardless of whether any Class B Certificateholder has
elected to exercise its right to purchase Equipment Notes under this Section
2.07 (and so long as no Additional Certificateholder has elected to exercise
its right to purchase Equipment Notes issued under such Indenture pursuant to
this Section 2.07 (upon such election and notification thereof, the right
specified in this Section 2.07(b) shall be suspended and (x) upon consummation
of the purchase pursuant to such election, such right shall be terminated with
respect to such Indenture, or (y) upon failure to consummate such purchase on
the proposed purchase date, such right shall be revived)), any Class C
Certificateholder may, upon 15 days’ prior written notice to the 

29

Subordination
Agent, each Trustee (and each such Trustee shall promptly provide such notice
to all Certificateholders of its Trust) and the applicable Loan Trustee,
purchase on the third Business Day next following the expiry of such 15-day
notice period all, but not less than all, of the Series A Equipment Notes and

Subordination Agent for a purchase price equal to the sum of the aggregate Note
Target Price for such Series A Equipment Notes and Series B Equipment Notes
plus an amount equal to Excess Liquidity Obligations in respect of such
Indenture accrued as of the date of such purchase. If prior to the end of such
15-day period, any other holder of the Class C Certificates notifies the
Subordination Agent, each Trustee (and each such Trustee shall promptly notify
all Certificateholders of the applicable Trust, including the purchasing Class
C Certificateholder) and each applicable Loan Trustee that it wishes to
participate in such purchase, then such other Certificateholder may join with
the purchasing Certificateholder to purchase such Series A Equipment Notes and
Series B Equipment Notes pro rata based on the interest in the Class C Trust
held by each such Certificateholder compared to such interests held by all such
participating Certificateholders. 

                    (c)
If an Equipment Note Buy-Out Event has occurred and is continuing with respect
to any Indenture, then regardless of whether any Class B Certificateholder or
Class C Certificateholder (or, if applicable, any Senior Additional
Certificateholder (as defined below)) has elected to exercise its right to
purchase Equipment Notes under this Section 2.07 (and so long as no Junior Additional
Certificateholder (as defined below) has elected to exercise its right to
purchase Equipment Notes issued under such Indenture pursuant to this Section
2.07 (upon such election and notification thereof, the right specified in this
Section 2.07(c) shall be suspended and (x) upon consummation of the purchase
pursuant to such election, such right shall be terminated with respect to such
Indenture, or (y) upon failure to consummate such purchase on the proposed
purchase date, such right shall be revived)), any Additional Certificateholder
may, upon 15 days’ prior written notice to the Subordination Agent, each
Trustee (and each such Trustee shall promptly provide such notice to all
Certificateholders of the applicable Trust) and the applicable Loan Trustee,
purchase on the third Business Day next following the expiry of such 15-day
notice period all, but not less than all, of the Series A Equipment Notes, the
Series B Equipment Notes and Series C Equipment Notes (and, if applicable, any
Senior Additional Equipment Notes (as defined below)) issued under such
Indenture and held by the Subordination Agent for a purchase price equal to the
sum of the aggregate Note Target Price for such Series A Equipment Notes,
Series B Equipment Notes and Series C Equipment Notes (and, if applicable, any
Senior Additional Equipment Notes) plus an amount equal to the Excess Liquidity
Obligations in respect of such Indenture accrued as of the date of such
purchase. If prior to the end of such 15-day period, any other holder of such
class of Additional Certificates notifies the Subordination Agent, each Trustee
(and each such Trustee shall promptly notify all Certificateholders of the
applicable Trust, including the purchasing Additional Certificateholder) and
each applicable Loan Trustee that it wishes to participate in such purchase,
then such other Certificateholder may join with the purchasing
Certificateholder to purchase such Series A Equipment Notes, Series B Equipment
Notes and Series C Equipment Notes (and, if applicable, any Senior Additional
Equipment Notes) pro rata based on the interest in the applicable Trust held by
each such Certificateholder compared to such interests held by all such
participating Certificateholders.

pro rata on the basis of the amounts of all such deficiencies and/or
unreimbursed Liquidity Obligations payable to each Liquidity Provider; 

                    fifth,

“fourth” on the basis of such amounts in respect of each Liquidity Provider; 

                    sixth,
such amount as shall be required to reimburse or pay (i) the Subordination
Agent for any Tax (other than Taxes imposed on compensation paid hereunder),
expense, fee, charge or other loss incurred by, or any other amount payable to,

36

Note that is
no longer held by the Subordination Agent (to the extent that such payments
relate to periods after such Equipment Note ceases to be held by the
Subordination Agent). 

                    Section
3.03. Other Payments. (a) Any payments received by the Subordination
Agent for which no provision as to the application thereof is made in this
Agreement shall be distributed by the Subordination Agent (i) in the order of
priority specified in Section 3.02 hereof and (ii) to the extent received or
realized at any time after the Final Distributions for each Class of
Certificates have been made, in the manner provided in clause “first” of
Section 3.02 hereof. 

                    (b)
Notwithstanding the priority of payments specified in Section 3.02, in the
event any Investment Earnings on amounts on deposit in any Cash Collateral
Account resulting from an Unapplied Provider Advance are deposited in the
Collection Account or the Special Payments Account, such Investment Earnings
shall be used to pay interest payable in respect of such Unapplied Provider
Advance to the extent of such Investment Earnings. 

                    (c)
If the Subordination Agent receives any Scheduled Payment after the Scheduled
Payment Date relating thereto, but prior to such payment becoming an Overdue
Scheduled Payment, then the Subordination Agent shall deposit such Scheduled
Payment in the Collection Account and promptly distribute such Scheduled
Payment in accordance with the priority of distributions set forth in Section
3.02; provided that, for the purposes of this Section 3.03(c) only, each
reference in clause “tenth”, “twelfth” or “fourteenth” of Section 3.02 to
“Distribution Date” shall be deemed to refer to such Scheduled Payment Date. 

                    Section
3.04. Payments to the Trustees and the Liquidity Providers. Any amounts
distributed hereunder to any Liquidity Provider shall be paid to such Liquidity
Provider by wire transfer of funds to the address such Liquidity Provider shall
provide to the Subordination Agent. The Subordination Agent shall provide a
Written Notice of any such transfer to the applicable Liquidity Provider at the
time of such transfer. Any amounts distributed hereunder by the Subordination
Agent to any Trustee that is not the same institution as the Subordination
Agent shall be paid to such Trustee by wire transfer of funds at the address
such Trustee shall provide to the Subordination Agent. 

                    Section
3.05. Liquidity Facilities. (a) Interest Drawings. If on any
Distribution Date, after giving effect to the subordination provisions of this
Agreement, the Subordination Agent shall not have sufficient funds for the
payment of any amounts due and owing in respect of accrued interest on the
Class A Certificates or the Class B Certificates (at the Stated Interest Rate
for such Class of Certificates) (other than any amount of interest which was
due and payable on the Class A Certificates or the Class B Certificates on such
Distribution Date but which remains unpaid due to the failure of the Depositary
to pay any amount of accrued interest on the Deposits on such Distribution
Date), then, prior to 12:30 p.m. (New York City time) on such Distribution
Date, (i) the Subordination Agent shall request a drawing (each such drawing,
an “Interest Drawing”) under the Liquidity Facility with respect to such Class
of Certificates in an amount equal to the lesser of (x) an amount sufficient to
pay the amount of such accrued interest shortfall (at the applicable Stated
Interest Rate for such Class of Certificates) and (y) the Available Amount
under such Liquidity Facility, and shall upon receipt of such amount pay such
amount to the Trustee with respect to each such Class of Certificates in
payment of such accrued interest shortfall.  

37

                    (b)
Application of Interest Drawings. Notwithstanding anything to the
contrary contained in this Agreement, (i) all payments received by the
Subordination Agent in respect of an Interest Drawing under the Class A
Liquidity Facility and all amounts withdrawn by the Subordination Agent from
the Class A Cash Collateral Account, and payable in each case to the Class A
Certificateholders or the Class A Trustee, shall be promptly distributed to the
Class A Trustee, and (ii) all payments received by the Subordination Agent in
respect of an Interest Drawing under the Class B Liquidity Facility and all
amounts withdrawn by the Subordination Agent from the Class B Cash Collateral
Account, and payable in each case to the Class B Certificateholders or the
Class B Trustee, shall be promptly distributed to the Class B Trustee. 

                    (c)
Downgrade Drawings. Each Liquidity Provider will promptly, but in any
event within ten days of its receipt of notice thereof, deliver notice of any
downgrading of its debt ratings to the Subordination Agent and Delta. If at any
time a Downgrade Event occurs with respect to any Liquidity Provider, within 10
days after such downgrading (but not later than the expiration date of the
Liquidity Facility issued by such Liquidity Provider in respect of which the
Downgrade Event occurs (the “Downgraded Facility”)), such Liquidity Provider or
Delta may arrange for a Replacement Liquidity Provider to issue and deliver a
Replacement Liquidity Facility to the Subordination Agent. If a Downgraded
Facility has not been replaced in accordance with the terms of this paragraph,
the Subordination Agent shall, on such 10th day (or if such 10th day is not a
Business Day, on the next succeeding Business Day) (or, if earlier, on the
expiration date of such Downgraded Facility), request a drawing in accordance
with and to the extent permitted by such Downgraded Facility (such drawing, a
“Downgrade Drawing”) of all available and undrawn amounts thereunder. Amounts
drawn pursuant to a Downgrade Drawing shall be maintained and invested as
provided in Section 3.05(f). Subject to Section 3.05(e)(iii), the applicable
Liquidity Provider may also arrange for a Replacement Liquidity Provider to
issue and deliver a Replacement Liquidity Facility at any time after such
Downgrade Drawing so long as such Downgrade Drawing has not been reimbursed in
full to such Liquidity Provider. 

                    (d)
Non-Extension Drawings. If any Liquidity Facility with respect to any
Class of Certificates is scheduled to expire on a date (the “Stated Expiration
Date”) prior to the date that is 15 days after the Final Legal Distribution
Date for such Class of Certificates, then no earlier than the 60th day and no
later than the 40th day prior to the then applicable Stated Expiration Date,
the Subordination Agent shall request in writing that such Liquidity Provider
extend the Stated Expiration Date to the earlier of (i) the date that is 15
days after the Final Legal Distribution Date for such Class of Certificates and
(ii) the date that is the day immediately preceding the 364th day after the
last day of the Consent Period (unless the obligations of such Liquidity
Provider thereunder are earlier terminated in accordance with such Liquidity
Facility). Whether or not the applicable Liquidity Provider has received a
request from the Subordination Agent, the Liquidity Provider shall by notice
(the “Consent Notice”) to the Subordination Agent, during the period commencing
on the date that is 60 days prior to the then effective Stated Expiration Date
(or if earlier, the date of such Liquidity Provider’s receipt of such request,
if any, from the Subordination Agent) and ending on the date that is 25 days
prior to such Stated Expiration Date (the “Consent Period”) advise the
Subordination Agent whether, in its sole discretion, it agrees to so extend the
Stated Expiration Date; provided that such extension shall not be
effective with respect to such Liquidity Provider if, by notice (the “Withdrawal
Notice”) 

38

to the
Subordination Agent prior to the end of the Consent Period, such Liquidity
Provider revokes its Consent Notice. If the Liquidity Provider advises the
Subordination Agent on or before the end of the Consent Period that such Stated
Expiration Date shall not be so extended or fails to irrevocably and
unconditionally advise the Subordination Agent on or before the end of the
Consent Period that such Stated Expiration Date shall be so extended or gives a
Withdrawal Notice to the Subordination Agent prior to the end of the Consent
Period (and, in each case, if the Liquidity Provider shall not have been
replaced in accordance with Section 3.05(e)), the Subordination Agent shall, on
the date on which the Consent Period ends (or as soon as possible thereafter
but prior to the Stated Expiration Date), in accordance with and to the extent
permitted by the terms of the expiring Liquidity Facility (a “Non-Extended
Facility”), request a drawing under such expiring Liquidity Facility (such drawing,
a “Non-Extension Drawing”) of all available and undrawn amounts thereunder.
Amounts drawn pursuant to a Non-Extension Drawing shall be maintained and
invested in accordance with Section 3.05(f). If any amounts shall be drawn
pursuant to a Non-Extension Drawing and, within 30 days thereafter, the
Liquidity Provider shall not have been replaced, then at any time following the
45th day after such Non-Extension Drawing, the Liquidity Provider may, by
written notice to the Subordination Agent, agree to reinstate the Liquidity
Facility on the terms of the existing Liquidity Facility for a period ending on
the 364th day after the end of the Consent Period; provided, however, that in
such event the Liquidity Provider shall reimburse the Subordination Agent for
any costs actually incurred by or on behalf of the Subordination Agent in
drawing pursuant to the Non-Extension Drawing and funding the Cash Collateral
Account or otherwise in connection with the NonExtension Drawing.  

                    (e)
Issuance of Replacement Liquidity Facility. (i) Subject to Section
3.05(e)(iii), at any time, Delta may, at its option, with cause or without
cause, arrange for a Replacement Liquidity Facility to replace any Liquidity
Facility for any Class of Certificates (including any Replacement Liquidity
Facility provided pursuant to Section 3.05(e)(ii)); provided, however, that if
the initial Liquidity Provider is replaced it shall be replaced with respect to
all Liquidity Facilities under which it is a Liquidity Provider. If such
Replacement Liquidity Facility is provided at any time after a Downgrade
Drawing, a Non-Extension Drawing or a Special Termination Drawing has been
made, all funds on deposit in the relevant Cash Collateral Account resulting
from such Downgrade Drawing or Non-Extension Drawing will be returned to the
Liquidity Provider being replaced. 

                    (ii)
If any Liquidity Provider shall determine not to extend its Liquidity Facility
in accordance with Section 3.05(d), then such Liquidity Provider may, at its
option, arrange for a Replacement Liquidity Facility to replace such Liquidity
Facility during the period no earlier than 40 days and no later than 25 days
prior to the then effective Stated Expiration Date of such Liquidity Facility.
At any time after a Non-Extension Drawing has been made under any Liquidity
Facility, the Liquidity Provider thereunder may, at its option, arrange for a
Replacement Liquidity Facility to replace the Liquidity Facility under which
such NonExtension Drawing has been made. 

                    (iii)
No Replacement Liquidity Facility arranged by Delta or a Liquidity Provider in
accordance with clause (i) or (ii) above or pursuant to Section 3.05(c),
respectively, shall become effective and no such Replacement Liquidity Facility
shall be deemed a “Liquidity Facility” under the Operative Agreements, unless
and until (A) each of the conditions referred to 

39

in sub-clauses
(iv)(x) and (z) below shall have been satisfied, (B) if such Replacement
Liquidity Facility shall materially adversely affect the rights, remedies,
interests or obligations of the Class A Certificateholders or the Class B
Certificateholders under any of the Operative Agreements, the applicable
Trustee shall have consented, in writing, to the execution and issuance of such
Replacement Liquidity Facility and (C) in the case of a Replacement Liquidity
Facility arranged by a Liquidity Provider under Section 3.05(e)(ii) or pursuant
to Section 3.05(c), such Replacement Liquidity Facility is reasonably acceptable
to Delta. 

                    (iv)
In connection with the issuance of each Replacement Liquidity Facility, the
Subordination Agent shall (x) prior to the issuance of such Replacement
Liquidity Facility, obtain written confirmation from each Rating Agency that
such Replacement Liquidity Facility will not cause a reduction of any rating
then in effect for any Class of Certificates by such Rating Agency (without
regard to any downgrading of any rating of any Liquidity Provider being
replaced pursuant to Section 3.05(c)), (y) pay all Liquidity Obligations then
owing to the replaced Liquidity Provider (which payment shall be made first
from available funds in the applicable Cash Collateral Account as described in
Section 3.05(f), and thereafter from any other available source, including,
without limitation, a drawing under the Replacement Liquidity Facility) and (z)
cause the issuer of the Replacement Liquidity Facility to deliver the
Replacement Liquidity Facility to the Subordination Agent, together with a legal
opinion opining that such Replacement Liquidity Facility is an enforceable
obligation of such Replacement Liquidity Provider. 

                    (v)
Upon satisfaction of the conditions set forth in clauses (iii) and (iv) of this
Section 3.05(e) with respect to a Replacement Liquidity Facility, (1) the
replaced Liquidity Facility shall terminate, (2) the Subordination Agent shall,
if and to the extent so requested by Delta or the Liquidity Provider being
replaced, execute and deliver any certificate or other instrument required in
order to terminate the replaced Liquidity Facility, shall surrender the
replaced Liquidity Facility to the Liquidity Provider being replaced and shall
execute and deliver the Replacement Liquidity Facility and any associated Fee
Letter, (3) each of the parties hereto shall enter into any amendments to this
Agreement necessary to give effect to (a) the replacement of the applicable
Liquidity Provider with the applicable Replacement Liquidity Provider and (b)
the replacement of the applicable Liquidity Facility with the applicable
Replacement Liquidity Facility, and (4) the applicable Replacement Liquidity
Provider shall be deemed to be a Liquidity Provider with the rights and
obligations of a Liquidity Provider hereunder and under the other Operative
Agreements and such Replacement Liquidity Facility shall be deemed to be a
Liquidity Facility hereunder and under the other Operative Agreements. 

                    (f)
Cash Collateral Accounts; Withdrawals; Investments. In the event the
Subordination Agent shall draw all available amounts under the Class A
Liquidity Facility or the Class B Liquidity Facility pursuant to Section
3.05(c), 3.05(d), 3.05(i) or 3.05(k), or in the event amounts are to be
deposited in the Class A Cash Collateral Account or the Class B Cash Collateral
Account pursuant to subclause (A) or (B) of clause “fourth” of Section 3.02,
amounts so drawn or to be deposited, as the case may be, shall be deposited by
the Subordination Agent in the Class A Cash Collateral Account or the Class B
Cash Collateral Account, as applicable. All amounts on deposit in each Cash
Collateral Account shall be invested and reinvested in Eligible Investments in
accordance with Section 2.02(b). 

40

                    On
each Interest Payment Date (or, in the case of any Special Distribution Date
with respect to the distribution of a Special Payment, on such Special
Distribution Date), Investment Earnings on amounts on deposit in each Cash
Collateral Account with respect to any Liquidity Facility (or in the case of
any Special Distribution Date with respect to the distribution of a Special
Payment, so long as no Indenture Event of Default shall have occurred and be
continuing under any Indenture, a fraction of such Investment Earnings equal to
the Section 2.04 Fraction) shall be deposited in the Collection Account (or, in
the case of any Special Distribution Date with respect to the occurrence of a
Special Payment, the Special Payments Account) and applied on such Interest
Payment Date (or Special Distribution Date, as the case may be) in accordance
with Section 3.02 or 3.03 (as applicable). The Subordination Agent shall
deliver a written statement to Delta and each Liquidity Provider one day prior
to each Interest Payment Date and Special Distribution Date setting forth the
aggregate amount of Investment Earnings held in the Cash Collateral Accounts as
of such date. In addition, from and after the date funds are so deposited, the
Subordination Agent shall make withdrawals from such accounts as follows: 

	
 

	
 

	
 

	
          (i)
  on each Distribution Date, the Subordination Agent shall, to the extent it
  shall not have received funds to pay accrued and unpaid interest due and
  owing on the Class A Certificates (at the applicable Stated Interest Rate for
  the Class A Certificates) after giving effect to the subordination provisions
  of this Agreement, withdraw from the Class A Cash Collateral Account, and pay
  to the Class A Trustee, an amount equal to the lesser of (x) an amount
  necessary to pay accrued and unpaid interest (at the applicable Stated
  Interest Rate for the Class A Certificates) on such Class A Certificates and
  (y) the amount on deposit in the Class A Cash Collateral Account; 

	
 

	
 

	
 

	
          (ii)
  on each Distribution Date, the Subordination Agent shall, to the extent it
  shall not have received funds to pay accrued and unpaid interest due and
  owing on the Class B Certificates (at the applicable Stated Interest Rate for
  the Class B Certificates) after giving effect to the subordination provisions
  of this Agreement, withdraw from the Class B Cash Collateral Account, and pay
  to the Class B Trustee, an amount equal to the lesser of (x) an amount
  necessary to pay accrued and unpaid interest (at the Stated Interest Rate for
  the Class B Certificates) on such Class B Certificates and (y) the amount on
  deposit in the Class B Cash Collateral Account; 

	
 

	
 

	
 

	
          (iii)
  on each date on which the Pool Balance of the Class A Trust shall have been
  reduced by payments made to the Class A Certificateholders pursuant to
  Section 3.02 hereof or pursuant to Section 2.03 of the Escrow and Paying
  Agent Agreement for such Class, the Subordination Agent shall withdraw from
  the Class A Cash Collateral Account such amount as is necessary so that,
  after giving effect to the reduction of the Pool Balance on such date (and
  any reduction in the amounts on deposit in the Class A Cash Collateral
  Account resulting from a prior withdrawal of amounts on deposit in the Class
  A Cash Collateral Account on such date) and any transfer of Investment
  Earnings from such Cash Collateral Account to the Collection Account or the
  Special Payments Account on such date, an amount equal to the sum of the
  Required Amount (with respect to the Class A Liquidity Facility) plus (if on
  a Distribution Date not coinciding with an Interest Payment Date) Investment
  Earnings on deposit in such Cash Collateral Account (after giving effect to
  any such transfer of Investment Earnings) will be on deposit in the 

41

	
 

	
 

	
 

	
Class A Cash
  Collateral Account and shall first, pay such withdrawn amount to the Class A
  Liquidity Provider until the Liquidity Obligations (with respect to the Class
  A Certificates) owing to such Liquidity Provider shall have been paid in
  full, and second, deposit any remaining withdrawn amount in the Collection
  Account; 

	
 

	
 

	
 

	
          (iv)
  on each date on which the Pool Balance of the Class B Trust shall have been
  reduced by payments made to the Class B Certificateholders pursuant to
  Section 3.02 hereof or pursuant to Section 2.03 of the Escrow and Paying
  Agent Agreement for such Class, the Subordination Agent shall withdraw from
  the Class B Cash Collateral Account such amount as is necessary so that,
  after giving effect to the reduction of the Pool Balance on such date (and
  any reduction in the amounts on deposit in the Class B Cash Collateral
  Account resulting from a prior withdrawal of amounts on deposit in the Class
  B Cash Collateral Account on such date) and any transfer of Investment
  Earnings from such Cash Collateral Account to the Collection Account or the
  Special Payments Account on such date, an amount equal to the sum of the
  Required Amount (with respect to the Class B Liquidity Facility) plus (if on
  a Distribution Date not coinciding with an Interest Payment Date) Investment
  Earnings on deposit in such Cash Collateral Account (after giving effect to
  any such transfer of Investment Earnings) will be on deposit in the Class B
  Cash Collateral Account and shall first, pay such withdrawn amount to the
  Class B Liquidity Provider until the Liquidity Obligations (with respect to
  the Class B Certificates) owing to such Liquidity Provider shall have been
  paid in full, and second, deposit any remaining withdrawn amount in the
  Collection Account; 

	
 

	
 

	
 

	
          (v)
  if a Replacement Liquidity Facility for any relevant Class of Certificates
  shall be delivered to the Subordination Agent following the date on which
  funds have been deposited into the Cash Collateral Account for such Class of
  Certificates, the Subordination Agent shall withdraw all amounts remaining on
  deposit in such Cash Collateral Account and shall pay such amounts to the
  replaced Liquidity Provider until all Liquidity Obligations owed to such
  Person shall have been paid in full, and deposit any remaining amount in the
  Collection Account; and 

	
 

	
 

	
 

	
          (vi)
  following the payment of Final Distributions with respect to any Class of
  Certificates covered by a Liquidity Facility, on the date on which the
  Subordination Agent shall have been notified by the Liquidity Provider for
  such Class of Certificates that the Liquidity Obligations owed to such
  Liquidity Provider have been paid in full, the Subordination Agent shall
  withdraw all amounts on deposit in the Cash Collateral Account in respect of
  such Class of Certificates and deposit such amounts in the Collection
  Account. 

                    (g)
Reinstatement. With respect to any Interest Drawing under the Liquidity
Facility for any relevant Trust, upon the reimbursement of the applicable
Liquidity Provider for all or any part of the amount of such Interest Drawing,
together with any accrued interest thereon, the Available Amount of such
Liquidity Facility shall be reinstated by an amount equal to the amount of such
Interest Drawing so reimbursed to the applicable Liquidity Provider but not to
exceed the Stated Amount for such Liquidity Facility; provided, however, that
the Available Amount of such Liquidity Facility shall not be so reinstated in
part or in full at any time if (x) both a Performing Note Deficiency exists and
a Liquidity Event of Default shall have 

42

occurred and
be continuing with respect to the relevant Liquidity Facility or (y) a Final
Drawing, Downgrade Drawing, Non-Extension Drawing or a Special Termination
Drawing shall have occurred with respect to such Liquidity Facility or an
Interest Drawing shall have been converted into a Final Drawing. In the event
that, with respect to any particular Liquidity Facility, (i) funds are
withdrawn from the related Cash Collateral Account pursuant to clause (i), or

Downgraded Facility or a Non-Extended Facility at a time when unreimbursed
Interest Drawings under such Liquidity Facility have reduced the Available
Amount thereunder to zero, then funds received by the Subordination Agent at

and a Liquidity Event of Default shall have occurred and be continuing with
respect to such Liquidity Facility or (y) any time after a Final Drawing shall
have occurred with respect to such Liquidity Facility shall be deposited in

                    (j)
Adjustments of Stated Amount. Promptly following each date on which the
Required Amount of the Liquidity Facility for a relevant Class of Certificates
is reduced as a result of a reduction in the Pool Balance with respect to such
Certificates or otherwise, the Subordination Agent shall, if any such Liquidity
Facility provides for reductions of the Stated Amount of such Liquidity
Facility and if such reductions are not automatic, request such Liquidity
Provider for such Class of Certificates to reduce such Stated Amount to an
amount equal to the Required Amount with respect to such Liquidity Facility (as

                    (m)

consent to the assignment by any Liquidity Provider of any of its rights or
obligations under any Liquidity Facility or any interest therein unless (i)
Delta shall have consented to such assignment and (ii) each Rating Agency shall
have provided a Ratings Confirmation in respect of such assignment; provided,
that the Subordination Agent shall consent to such assignment if the conditions
in the foregoing clauses (i) and (ii) are satisfied, and the foregoing is not

Liquidity Provider under Section 3.05(e)(ii). 

ARTICLE IV

EXERCISE OF REMEDIES

                    Section
4.01. Directions from the Controlling Party. (a) (i) Following the
occurrence and during the continuation of an Indenture Event of Default under
any Indenture, the Controlling Party (except as otherwise provided in Section
2.06(d)) shall direct the Subordination Agent, as the holder of the Equipment
Notes issued under such Indenture, which in turn shall direct the Loan Trustee
under such Indenture, in the exercise of remedies available to the holders of
such Equipment Notes, including, without limitation, the ability to vote all
such Equipment Notes held by the Subordination Agent in favor of Accelerating
such Equipment Notes in accordance with the provisions of such Indenture.
Subject to Section 4.01(a)(iii), if the Equipment Notes issued pursuant to any
Indenture have been Accelerated following an Indenture Event of Default with
respect thereto, the Controlling Party may direct the Subordination Agent to
sell, assign, contract to sell or otherwise dispose of and deliver all (but not
less than all) of such Equipment Notes to any Person at public or private sale,
at any location at the option of the Controlling Party, all upon such terms and
conditions as it may reasonably deem advisable and in accordance with
applicable law. 

                    (ii)
Following the occurrence and during the continuation of an Indenture Event of
Default under any Indenture, in the exercise of remedies pursuant to such
Indenture, the Loan Trustee under such Indenture may be directed to lease the
related Aircraft to any Person (including Delta) so long as the Loan Trustee in
doing so acts in a “commercially reasonable” manner within the meaning of
Article 9 of the Uniform Commercial Code as in effect in any applicable
jurisdiction (including Sections 9-610 and 9-627 thereof). 

                    (iii)
Notwithstanding the foregoing, so long as any Certificates remain Outstanding,
during the period ending on the date which is nine months after the earlier of
(x) the Acceleration of the Equipment Notes issued pursuant to any Indenture or
(y) the occurrence of a Delta Bankruptcy Event, without the consent of each
Trustee (other than the Trustee of any Trust all of the Certificates of which
are held or beneficially owned by Delta and/or its Affiliates), no Aircraft
subject to the Lien of such Indenture or such Equipment Notes may be sold if
the net proceeds from such sale would be less than the Minimum Sale Price for
such Aircraft or such Equipment Notes. 

                    (iv)
Upon the occurrence and continuation of an Indenture Event of Default under any
Indenture, the Subordination Agent will obtain three desktop appraisals from the
Appraisers selected by the Controlling Party setting forth the current market
value, current lease

44

rate and distressed
value (in each case, as defined by the International Society of Transport
Aircraft Trading or any successor organization) of the Aircraft subject to such
Indenture (each such appraisal, an “Appraisal”and the current market value appraisals being referred to herein as
the “Post-Default Appraisals”). For
so long as any Indenture Event of Default shall be continuing under any Indenture,
and without limiting the right of the Controlling Party to request more
frequent Appraisals, the Subordination Agent will obtain updated Appraisals on
the date that is 364 days from the date of the most recent Appraisal (or if a
Delta Bankruptcy Event shall have occurred and is continuing, on the date that
is 180 days from the date of the most recent Appraisal) and shall (acting on
behalf of each Trustee) post such Appraisals on DTC’s Internet board or make
such other commercially reasonable efforts as the Subordination Agent may deem
appropriate to make such Appraisals available to all Certificateholders. 

                    (b)
Following the occurrence and during the continuance of an Indenture Event of
Default under any Indenture, the Controlling Party shall take such actions as
it may reasonably deem most effectual to complete the sale or other disposition
of the relevant Aircraft or Equipment Notes. In addition, in lieu of any sale,
assignment, contract to sell or other disposition, the Controlling Party may
maintain or cause the Subordination Agent to maintain possession of such
Equipment Notes and continue to apply monies received in respect of such
Equipment Notes in accordance with Article III hereof. In addition, in lieu of
such sale, assignment, contract to sell or other disposition, or in lieu of
such maintenance of possession, the Controlling Party may direct the
Subordination Agent to, subject to the terms and conditions of the related
Indenture, instruct the Loan Trustee under such Indenture to foreclose on the
Lien on the related Aircraft or to take any other remedial action permitted
under such Indenture or under any applicable law. 

                    (c)
If following a Delta Bankruptcy Event and during the pendency thereof, the
Controlling Party receives a proposal from or on behalf of Delta to restructure
the financing of any one or more of the Aircraft, the Controlling Party shall
promptly thereafter give the Subordination Agent, each Trustee and each
Liquidity Provider that has not made a Final Advance notice of the material
economic terms and conditions of such restructuring proposal whereupon the
Subordination Agent acting on behalf of each Trustee shall post such terms and
conditions of such restructuring proposal on DTC’s Internet board or make such
other commercially reasonable efforts as the Subordination Agent may deem
appropriate to make such terms and conditions available to all
Certificateholders. Thereafter, neither the Subordination Agent nor any
Trustee, whether acting on instructions of the Controlling Party or otherwise,
may, without the consent of each Trustee, enter into any term sheet,
stipulation or other agreement (a “Restructuring Arrangement”) (whether in the
form of an adequate protection stipulation, an extension under Section 1110(b)
of the Bankruptcy Code or otherwise) to effect any such restructuring proposal
with or on behalf of Delta unless and until the material economic terms and
conditions of such restructuring shall have been made available to all Certificateholders
and each Liquidity Provider that has not made a Final Advance for a period of
not less than 15 calendar days (except that such requirement shall not apply to
any such term sheet, stipulation or other agreement that is to be effective on
or as of any date occurring during the 60-Day Period and that is initially
effective for a period not exceeding three months from the expiry of the 60-Day
Period (an “Interim Restructuring Arrangement”)). The foregoing provisions of
this Section 4.01(c) (i) shall not apply to any extension of a Restructuring
Arrangement with respect to which such provisions have been complied with in
connection with 

45

the original
entry thereof if the possibility of such extension has been disclosed in
satisfaction of the requirements of such provisions and such extension shall
not amend or modify any of the other terms and conditions of such Restructuring
Arrangement and (ii) shall apply to the initial extension of an Interim
Restructuring Arrangement beyond the three months following the expiry of the
60-Day Period but not to any subsequent extension of such Interim Restructuring
Arrangement, if the possibility of such subsequent extension has been disclosed
in satisfaction of the notification requirements of such provisions and such
subsequent extension shall not amend or modify any of the other terms and
conditions of such Interim Restructuring Arrangement. In the event that any
Certificateholder gives irrevocable notice of the exercise of (i) its right to
purchase any Equipment Notes pursuant to Section 2.07 hereof or (ii) its right
to purchase all (but not less than all) of the Class of Certificates
represented by the then Controlling Party pursuant to the applicable Trust
Agreement, in either case, prior to the expiry of the 15-day notice period
specified above, such Controlling Party may not direct the Subordination Agent
or any Trustee to enter into (i) in the case of such purchase of Equipment
Notes, any such restructuring proposal with respect to the Aircraft related to such
Equipment Notes, or (ii) in the case of such purchase of Certificates, any such
restructuring proposal with respect to any of the Aircraft, in either case,
unless and until such Certificateholder shall fail to purchase such Equipment
Notes or Class of Certificates, as applicable, on the date that it is required
to make such purchase. 

                    Section
4.02. Remedies Cumulative. Each and every right, power and remedy given
to the Trustees, the Liquidity Providers, the Controlling Party or the Subordination
Agent specifically or otherwise in this Agreement shall be cumulative and shall
be in addition to every other right, power and remedy herein specifically given
or now or hereafter existing at law, in equity or by statute, and each and
every right, power and remedy whether specifically herein given or otherwise
existing may, subject always to the terms and conditions hereof, be exercised
from time to time and as often and in such order as may be deemed expedient by
any Trustee, any Liquidity Provider, the Controlling Party or the Subordination
Agent, as appropriate, and the exercise or the beginning of the exercise of any
right, power or remedy shall not be construed to be a waiver of the right to
exercise at the same time or thereafter any other right, power or remedy. No
delay or omission by any Trustee, any Liquidity Provider, the Controlling Party
or the Subordination Agent in the exercise of any right, remedy or power or in
the pursuit of any remedy shall impair any such right, power or remedy or be
construed to be a waiver of any default or to be an acquiescence therein. 

                    Section
4.03. Discontinuance of Proceedings. In case any party to this Agreement
(including the Controlling Party in such capacity) shall have instituted any
Proceeding to enforce any right, power or remedy under this Agreement by
foreclosure, entry or otherwise, and such Proceeding shall have been
discontinued or abandoned for any reason or shall have been determined
adversely to the Person instituting such Proceeding, then and in every such
case each such party shall, subject to any determination in such Proceeding, be
restored to its former position and rights hereunder, and all rights, remedies
and powers of such party shall continue as if no such Proceeding had been
instituted. 

                    Section
4.04. Right of Certificateholders and the Liquidity Providers to Receive
Payments Not to Be Impaired. Anything in this Agreement to the contrary
notwithstanding but subject to each Trust Agreement, the right of any
Certificateholder or any Liquidity Provider, 

46

respectively, to receive payments hereunder
(including, without limitation, pursuant to Section 3.02) when due, or to
institute suit for the enforcement of any such payment on or after the
applicable Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder or such Liquidity Provider, respectively.

Subordination Agent shall have received indemnification against any risks that
may be incurred in connection therewith in form and substance reasonably
satisfactory to it, including, without limitation, adequate advances against
costs (including fees and expenses) that may be incurred by it in connection
therewith. The Subordination Agent shall not be required to take any action
under Article IV, nor shall any other provision of this Agreement or any other
Operative Agreement be deemed to impose a duty on the Subordination Agent to
take any action, if the Subordination Agent shall have been advised by outside
counsel that such action is contrary to the terms hereof or is otherwise
contrary to law. Under no circumstances shall the Subordination Agent be
required to expend or risk its own funds or otherwise incur any financial
liability in performing its duties or exercising its rights or powers hereunder
if it shall have reasonable grounds for believing that repayment of such funds
is not assured to it.

                    Section

Subordination Agent shall not have any duty or obligation to take or refrain

as may be necessary duly to discharge all Liens on any of the Trust Accounts or
any monies deposited therein that are attributable to the Subordination Agent
in its individual capacity and that are unrelated to the transaction
contemplated hereby and by the other Operative Agreements. 

                    Section
5.04. Notice from the Liquidity Providers and Trustees. If any Liquidity
Provider or Trustee has notice of an Indenture Event of Default or a Triggering

deliver any such notice.

such certificate shall constitute full protection to the Subordination Agent
for any action taken or omitted to be taken by it in good faith in reliance
thereon. As to any fact or matter relating to the Liquidity Providers or the
Trustees the manner of ascertainment of which is not specifically described
herein, the Subordination Agent may for all purposes hereof rely on a

this Agreement. 

                    Section

Subordination Agent hereunder may become a Certificateholder and have all

  the Subordination Agent otherwise becomes incapable of acting. 

                    If
the Subordination Agent resigns or is removed or if a vacancy exists in the
office of Subordination Agent for any reason (the Subordination Agent in such
event being referred to herein as the retiring Subordination Agent), the
Controlling Party (or the party that would be the Controlling Party if an
Indenture Event of Default had occurred) shall promptly appoint a successor
Subordination Agent. If a successor Subordination Agent shall not have been
appointed within 60 days after such notice of resignation or removal, the
retiring Subordination Agent, one or more of the Trustees or one or more of the
Liquidity Providers may petition any court of competent jurisdiction for the
appointment of a successor Subordination Agent to act until such time, if any,
as a successor shall have been appointed as provided above. 

                    A
successor Subordination Agent shall deliver (x) a written acceptance of its
appointment as Subordination Agent hereunder to the retiring Subordination
Agent and (y) a written assumption of its obligations hereunder and under each
Liquidity Facility to each party hereto, upon which the resignation or removal
of the retiring Subordination Agent shall become effective, and the successor
Subordination Agent shall have all the rights, powers and duties of the
Subordination Agent under this Agreement. The successor Subordination Agent
shall mail a notice of its succession to Delta, the Liquidity Providers and the
Trustees. The retiring Subordination Agent shall promptly transfer its rights
under each of the Liquidity Facilities and all of the property and all books
and records, or true, complete and correct copies thereof, held by it as
Subordination Agent to the successor Subordination Agent. 

                    If
the Subordination Agent fails to comply with Section 6.09 (to the extent
applicable), one or more of the Trustees or one or more of the Liquidity
Providers may petition a court of competent jurisdiction for the removal of the
Subordination Agent and the appointment of a successor Subordination Agent. 

                    Notwithstanding
the foregoing, no resignation or removal of the Subordination Agent shall be
effective unless and until a successor has been appointed. No appointment of a
successor Subordination Agent shall be effective unless and until the Rating
Agencies shall have delivered a Ratings Confirmation. 

                    (b)
Any corporation, bank, trust company or other financial institution into which
the Subordination Agent may be merged or converted or with which it may be
consolidated, or any corporation, bank, trust company or other financial
institution resulting from any merger, conversion or consolidation to which the
Subordination Agent shall be a party, or any corporation, bank, trust company
or other financial institution succeeding to all or substantially all of the
corporate trust business of the Subordination Agent, shall be the successor of
the Subordination Agent hereunder, provided that such corporation, bank, trust
company or other financial institution shall be otherwise qualified and
eligible under Section 6.09, without the execution or filing of any paper or
any further act on the part of any of the parties hereto, 

52

except that such corporation, bank, trust company or
other financial institution shall give prompt notice of such transaction to
Delta.

SUPPLEMENTS AND AMENDMENTS

                    Section
8.01. Amendments, Waivers, Etc. (a) This Agreement may not be
supplemented, amended or modified without the consent of each Trustee (acting,
except in the case of any amendment pursuant to Section 3.05(e)(v) or any
amendment contemplated by the last sentence of this Section 8.01(a), with the
consent of holders of Outstanding Certificates of the related Class evidencing
Fractional Undivided Interests in the related Trust aggregating not less than a
majority in interest in such Trust or as otherwise authorized pursuant to the
relevant Trust Agreement (including, without limitation, without the consent of
the Certificateholders to the extent permitted thereby, Section 9.01 of the
Basic Agreement)), the Subordination Agent and each Liquidity Provider;
provided, however, that this Agreement may be supplemented, amended or modified
without the consent of any Trustee in order (i) to cure any ambiguity or
omission or to correct any mistake, (ii) to correct or supplement any
provision, or (iii) to make any other provision in regard to matters or
questions arising hereunder that will not materially adversely affect the
interests of any Trustee or the holders of the related Class of Certificates,
and without the consent of any Liquidity Provider if such supplement, amendment
or modification is in accordance with Section 8.01(c) or (d); provided
further, however, that, if such supplement, amendment or modification
(x) would directly or indirectly amend, modify or supersede, or otherwise
conflict with, Section 2.02(b), 3.05(c), 3.05(e), 3.05(f) (other than the
last sentence thereof), 3.05(l), this proviso of 8.01(a), the last sentence of
8.01(a), 8.01(c), 8.01(d) or 9.06 (collectively, the “Delta Provisions”),
(y) would otherwise affect the interests of a potential Replacement
Liquidity Provider or of Delta with respect to its ability to replace any
Liquidity Facility or with respect to its payment obligations under any
Operative Agreement or (z) is made pursuant to the last sentence of this
Section 8.01(a) or pursuant to Section 8.01(c) or pursuant to Section
8.01(d), then such supplement, amendment or modification shall not be effective
without the additional written consent of Delta. Notwithstanding the foregoing,
without the consent of each Certificateholder affected thereby and each
Liquidity Provider, no supplement, amendment or modification of this Agreement
may (i) reduce the percentage of the interest in any Trust evidenced by
the Certificates issued by such Trust necessary to consent to modify or amend
any provision of this Agreement or to waive compliance therewith or (ii),
except as provided in the last sentence of this Section 8.01(a), Section
8.01(c) or Section 8.01(d), modify Section 2.04, 3.02 or 3.03 hereof relating
to the distribution of monies received by the Subordination Agent hereunder
from the Equipment Notes or pursuant to the Liquidity Facilities. Nothing
contained in this Section 8.01(a) shall require the consent of a Trustee
at any time following the payment of Final Distributions with respect to the
related Class of Certificates. If the Replacement Liquidity Facility for any
Liquidity Facility is to be comprised of more than one instrument as
contemplated by the definition of the term “Replacement Liquidity Facility”,
then each party hereto agrees to amend this Agreement and the other Operative
Agreements to incorporate appropriate mechanics for multiple Liquidity
Facilities for a single Trust. 

                    (b)
In the event that the Subordination Agent, as the registered holder of any
Equipment Notes, receives a request for its consent to any amendment,
supplement, 

53

modification, approval, consent or waiver under such
Equipment Notes, the Indenture pursuant to which such Equipment Notes were
issued or the related Participation Agreement or other related document,
(i) if no Indenture Event of Default shall have occurred and be continuing
with respect to such Indenture, the Subordination Agent shall request
directions with respect to each series of such Equipment Notes from the Trustee
of the Trust which holds such Equipment Notes and shall vote or consent in
accordance with the directions of such Trustee and (ii) if any Indenture
Event of Default shall have occurred and be continuing with respect to such
Indenture, the Subordination Agent will exercise its voting rights as directed
by the Controlling Party, subject to Sections 4.01 and 4.04.
Notwithstanding the foregoing, without the consent of each Liquidity Provider
and each Certificateholder holding Certificates representing a Fractional
Undivided Interest in the Equipment Notes under the applicable Indenture held
by the Subordination Agent, no such amendment, supplement, modification,
approval, consent or waiver shall (i) reduce the principal amount of, Premium,
if any, or interest on, any Equipment Note under such Indenture; (ii) change the
date on which any principal amount of, Premium, if any, or interest on any
Equipment Note under such Indenture, is due or payable; (iii) create any Lien
with respect to the Collateral subject to such Indenture prior to or pari passu
with the Lien thereon under such Indenture except such as are permitted by such
Indenture; provided that, without the consent of each Certificateholder,
no such amendment, supplement, modification, approval, consent or waiver shall
modify Section 3.03 or Section 9.02(a)(3) of such Indenture or deprive any
Certificateholder of the benefit of the Lien of such Indenture on such
Collateral, except as provided in connection with the exercise of remedies
under Article IV of such Indenture; (iv) reduce the percentage of the
outstanding principal amount of the Equipment Notes under such Indenture the
consent of whose holders is required for any supplemental agreement, or the
consent of whose holders is required for any waiver of compliance with certain
provisions of such Indenture or of certain defaults thereunder or their
consequences provided for in such Indenture; or (v) make any change in Section
4.05 or Section 9.02 of such Indenture, except to provide that certain other
provisions of such Indenture cannot be modified or waived without the consent
of each holder of an Equipment Note under such Indenture affected thereby.

                    (c)
 If Series B Equipment Notes or Series
C Equipment Notes (or any series of Additional Equipment Notes) issued with
respect to all of the Aircraft are redeemed and new Equipment Notes of
corresponding series are to be issued in accordance with the terms of Section
2.11(b) of each Indenture and Section 4(a)(v) of the Note Purchase Agreement,
such series of new Equipment Notes (the “Refinancing Equipment Notes”) shall be
issued to a new pass through trust (a “Refinancing Trust”) that issues a class
of pass through certificates (the “Refinancing Certificates”) to
certificateholders (the “Refinancing Certificateholders”) pursuant to a pass
through trust agreement (a “Refinancing Trust Agreement”) with a trustee (a
“Refinancing Trustee”). A Refinancing Trust, a Refinancing Trustee and the
Refinancing Certificates shall be subject to all of the provisions of this
Agreement in the same manner as the Trust, the Trustee and the Certificates of
the Class corresponding to the series of the refinanced Equipment Notes,
including, the subordination of the Refinancing Certificates to the
Administration Expenses, the Liquidity Obligations, the Class A Certificates and,
if applicable, the Class B Certificates. Such issuance of Refinancing Equipment
Notes and Refinancing Certificates and the amendment of this Agreement as
provided below shall require Ratings Confirmation and shall not materially
adversely affect any of the Trustees or any of the Liquidity Providers. This
Agreement shall be amended by written agreement of Delta and the

54

Subordination Agent to give effect to the issuance of the Refinancing
Certificates subject to the following terms and conditions:

	
   

  	
   

  
	
   

  	
            (i)
  the Refinancing Trustee shall be added as a party to this Agreement;

  
	
   

  	
   

  
	
   

  	
            (ii)
  the definitions of “Certificate”, “Class”, “Class B Certificates” (if
  applicable), “Class C Certificates” (if applicable), “Final Legal
  Distribution Date”, “Trust”, “Trust Agreement” and “Controlling Party” (and
  such other applicable definitions) shall be revised, as appropriate, to
  reflect such issuance (and the subordination of the Refinancing Certificates
  and the Refinancing Equipment Notes);

  
	
   

  	
   

  
	
   

  	
            (iii)
  the Refinancing Certificates may have the benefit of credit support similar
  to the Liquidity Facilities and claims for fees, interest, expenses,
  reimbursement of advances and other obligations arising from such credit
  support may rank pari passu with similar claims in respect of the Liquidity
  Facilities so long as Ratings Confirmation and the prior written consent of
  the Liquidity Providers shall have been obtained;

  
	
   

  	
   

  
	
   

  	
            (iv)
  the Refinancing Certificates cannot be issued to Delta but may be issued to
  any of Delta’s Affiliates so long as such Affiliate shall have bankruptcy
  remote and special purpose provisions in its certificate of incorporation or
  other organizational documents and any subsequent transfer of the Refinancing
  Certificates to any Affiliate of Delta shall be similarly restricted; and

  
	
   

  	
   

  
	
   

  	
            (v)
  the scheduled payment dates on the Refinancing Equipment Notes shall be the
  Regular Distribution Dates.

  

                    The
issuance of the Refinancing Certificates in compliance with all of the
foregoing terms of this Section 9.1(c) shall not require the consent of any of
the Trustees or the holders of any Class of Certificates. Each of the Liquidity
Providers hereby agrees and confirms that it shall be deemed to consent to any
issuance and amendment in accordance with this Section 9.01(c) (subject to the
Liquidity Providers’ consent right in Section 9.01(c)(iii)) and any such
issuance and amendment shall not affect any of its respective obligations under
the Liquidity Facilities, provided that a condition to the issuance of any
Refinancing Certificates issued in respect of a Class of Certificate with a
Liquidity Facility shall be the payment in full of all amounts owed to the
Liquidity Provider under such Liquidity Facility and the termination of such
Liquidity Facility upon the issuance of the Refinancing Certificates. The
Subordination Agent shall deliver to each Trustee and each Liquidity Provider
(other than the Liquidity Provider of such terminated Liquidity Facility) a
copy of the amendments made to this Agreement and all opinions, certificates
and other documents delivered in connection with the issuance of any
Refinancing Certificates.

                    (d)
Pursuant to the terms of Section 2.02
of each Indenture and Section 4(a)(v) of the Note Purchase Agreement, one or
more additional series of Equipment Notes (the “Additional Equipment Notes”),
which shall be subordinated in right of payment to the Series A Equipment
Notes, the Series B Equipment Notes and the Series C Equipment Notes under such
Indenture, may be issued at any time and from time to time. If any series of
Additional Equipment Notes is issued under any Indenture, such series of
Additional Equipment Notes shall 

55

be issued to a new pass through trust (an “Additional Trust”) that issues
a class of pass through certificates (the “Additional Certificates”) to
certificateholders (the “Additional Certificateholders”) pursuant to a pass
through trust agreement (an “Additional Trust Agreement”) with a trustee (an
“Additional Trustee”). In such case, this Agreement shall be amended by written
agreement of Delta and the Subordination Agent to provide for the subordination
of the Additional Certificates to the Administration Expenses, the Liquidity
Obligations, the Class A Certificates, the Class B Certificates and the Class C
Certificates and, if applicable, any previously issued class (or classes) of
Additional Certificates (in order of their issuance) (subject to clause (iii)
below). Such issuance and the amendment of this Agreement as provided below
shall require Ratings Confirmation and shall not materially adversely affect
any of the Trustees or any of the Liquidity Providers. This Agreement shall be
amended by written agreement of Delta and the Subordination Agent to give
effect to the issuance of any Additional Certificates subject to the following
terms and conditions:

                    (i)
the Additional Trustee shall be added as a party to this Agreement;

                    (ii)
the definitions of “Certificate”, “Class”, “Equipment Notes”, “Final Legal
Distribution Date”, “Trust”, “Trust Agreement” and “Controlling Party” (and
such other applicable definitions) shall be revised, as appropriate, to reflect
the issuance of the Additional Certificates (and the subordination thereof);

                    (iii)
Section 3.02 may be revised, with respect to each Class of Additional
Certificates, to provide for the distribution of “Adjusted Interest” for such
Class of Additional Certificates (calculated in a manner substantially similar
to the calculation of Class C Adjusted Interest) after the Class C Adjusted
Interest but before Expected Distributions on the Class A Certificates (it
being understood that the Rating Agencies, in connection with providing a
Ratings Confirmation, may require that such class of Additional Certificates be
rated);

                    (iv)
the Additional Certificates may have the benefit of credit support similar to
the Liquidity Facilities and claims for fees, interest, expenses, reimbursement
of advances and other obligations arising from such credit support may rank
pari passu with similar claims in respect of the Liquidity Facilities so long
as Ratings Confirmation and the prior written consent of the Liquidity
Providers shall have been obtained;

                    (v)
the Additional Certificates cannot be issued to Delta but may be issued to any
of Delta’s Affiliates so long as such Affiliate shall have bankruptcy remote
and special purpose provisions in its certificate of incorporation or other
organizational documents and any subsequent transfer of the Additional
Certificates to any Affiliate of Delta shall be similarly restricted; 

                    (vi)
the provisions of this Agreement governing payments with respect to Certificates
and related notices, including Sections 2.04, 3.01 and 3.02, shall be revised
to provide for distributions on such class of the Additional Certificates after
payment of Administration Expenses, the Liquidity Obligations, the Class A
Certificates, the Class B Certificates and the Class C Certificates (and, if
applicable, any previously issued class (or classes) of Additional Certificates
(in order of their issuance)), subject to clause (iii) above; and 

56

                    (vii)
the scheduled payment dates on such series of Additional Equipment Notes shall
be the Regular Distribution Dates.

                    The
issuance of the Additional Certificates in compliance with all of the foregoing
terms of this Section 8.01(d) shall not require the consent of any of the
Trustees or the holders of any Class of Certificates. Each of the Liquidity
Providers hereby agrees and confirms that it shall be deemed to consent to any
issuance and amendment in accordance with this Section 8.01(d) (subject to the
Liquidity Providers’ consent right in Section 8.01(d)(iv)) and any such
issuance and amendment shall not affect any of its respective obligations under
the Liquidity Facilities. The Subordination Agent shall deliver to each Trustee
and each Liquidity Provider a copy of the amendments made to this Agreement and
all opinions, certificates and other documents delivered in connection with the
issuance of any Additional Certificates.

                    Section
8.02. Subordination Agent Protected. If, in the reasonable opinion of
the institution acting as the Subordination Agent hereunder, any document
required to be executed by it pursuant to the terms of Section 8.01 adversely
affects any right, duty, immunity or indemnity with respect to such institution
under this Agreement or any Liquidity Facility, the Subordination Agent may in
its discretion decline to execute such document. 

                    Section
8.03. Effect of Supplemental Agreements. Upon the execution of any
amendment, consent or supplement hereto pursuant to the provisions hereof, this
Agreement shall be and shall be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Agreement of the parties hereto and beneficiaries
hereof shall thereafter be determined, exercised and enforced hereunder subject
in all respects to such modifications and amendments, and all the terms and
conditions of any such supplemental agreement shall be and be deemed to be part
of the terms and conditions of this Agreement for any and all purposes. In
executing or accepting any supplemental agreement permitted by this Article
VIII, the Subordination Agent shall be entitled to receive, and shall be fully
protected in relying upon, an opinion of counsel stating that the execution of
such supplemental agreement is authorized or permitted by this Agreement. 

                    Section
8.04. Notice to Rating Agencies. Promptly following its receipt of each
amendment, consent, modification, supplement or waiver contemplated by this
Article VIII, the Subordination Agent shall send a copy thereof to each Rating
Agency.

Certificates or Additional Certificates), on the one hand, and the Trustees
(and any refinancing Trustees or Additional Trustees) and the
Certificateholders (and any Refinancing Certificateholders or Additional
Certificateholders), on the other hand, and as among the Trustees (and any
Refinancing Trustees or Additional Trustees) and the related Certificateholders
(and any Refinancing Certificateholders or Additional Certificateholders) this
Agreement shall be a subordination agreement for purposes of Section 510 of the
United States Bankruptcy Code, as amended from time to time.

Notwithstanding the provisions of this Agreement, if prior to the payment in

respect of Equipment Notes or any other amount under the Indentures or other
Operative Agreements which, had the subordination provisions of this Agreement

have been distributed to such Person, then such payment, distribution or other
amount shall be received and held in trust by such Person and paid over or
delivered to the Subordination Agent for application as provided herein. 

                    (c)
If any Trustee, any Liquidity Provider or the Subordination Agent receives any
payment in respect of any obligations owing or amounts distributable hereunder
(or, in the case of the Liquidity Providers, in respect of the Liquidity Obligations),
which is subsequently invalidated, declared preferential, set aside and/or
required to be repaid to a trustee, receiver or other party, then, to the
extent of such payment, such obligations or amounts (or, in the case of the
Liquidity Providers, such Liquidity Obligations) intended to be satisfied shall
be revived and continue in full force and effect as if such payment had not
been received. 

                    (d)
The Trustees (on behalf of themselves and the holders of Certificates), the
Liquidity Providers and the Subordination Agent expressly confirm and agree
that the payment priorities and subordination specified in Articles II and III
shall apply in all circumstances, notwithstanding (x) the fact that the
obligations owed to the Trustees are secured by certain assets and the
Liquidity Obligations may not be so secured (y) the occurrence of a Delta
Bankruptcy Event or any similar event or occurrence relating to any other
Person (it being expressly agreed that the payment priorities and subordination
specified in Articles II and III shall apply whether or not a claim for
post-petition or post-filing interest is allowed in the proceedings resulting
from such Delta Bankruptcy Event or other event or occurrence). The Trustees
expressly agree (on behalf of themselves and the holders of Certificates) not
to assert priority over the holders of Liquidity Obligations (except as
specifically set forth in Section 3.02) due to their status as secured
creditors in any bankruptcy, insolvency or other legal proceeding. 

                    (e)
Each of the Trustees (on behalf of themselves and the holders of Certificates),
the Liquidity Providers and the Subordination Agent may take any of the
following actions without impairing its rights under this Agreement: 

	
   

  	
   

  
	
   

  	
            (i)
  obtain a Lien on any property to secure any amounts owing to it hereunder,
  including, in the case of the Liquidity Providers, the Liquidity Obligations;
  

  

60

	
   

  	
   

  
	
   

  	
   

  
	
   

  	
            
  (ii) obtain the primary or secondary obligation of any other obligor with
  respect to any amounts owing to it hereunder, including, in the case of the
  Liquidity Providers, any of the Liquidity Obligations; 

  
	
   

  	
   

  
	
   

  	
            
  (iii) renew, extend, increase, alter or exchange any amounts owing to it
  hereunder, including, in the case of the Liquidity Providers, any of the
  Liquidity Obligations, or release or compromise any obligation of any obligor
  with respect thereto; 

  
	
   

  	
   

  
	
   

  	
            
  (iv) refrain from exercising any right or remedy, or delay in exercising any
  right or remedy, which it may have; or 

  
	
   

  	
   

  
	
   

  	
            
  (v) take any other action which might discharge a subordinated party or a
  surety under applicable law; 

  

provided, however, that the taking of any such actions
by any of the Trustees, the Liquidity Providers or the Subordination Agent
shall not prejudice the rights or adversely affect the obligations of any other
party under this Agreement. 

                    Section
9.10. Governing Law. THIS AGREEMENT HAS BEEN DELIVERED IN THE STATE OF NEW
YORK AND 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
9.11. 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 and of all other Operative Agreements 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 District Court for the Southern District of New York, for
the purposes of any suit, action or other proceeding arising out of this
Agreement, the subject matter hereof or any of the transactions contemplated
hereby brought by any party or parties hereto or thereto, or their successors
or permitted assigns and (ii) waives, and agrees not to assert, by way of
motion, as a defense, or otherwise, in any such suit, action or proceeding,
that the suit, action or proceeding is brought in an inconvenient forum, that
the venue of the suit, action or proceeding is improper or 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)
EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS 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. Each of the parties warrants and
represents that it has reviewed this waiver with its legal counsel, and that it
knowingly and voluntarily waives its jury trial rights following consultation 

61

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. 

                    (c)
Each 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. 

                    Section
9.12. Non-Petition. Each Liquidity Provider covenants that until one
year and one day after the Equipment Notes have been paid in full, it shall not
acquiesce, petition or otherwise invoke or cause or join in invoking or causing
any Trust or any other Person to invoke the process of any governmental
authority for the purpose of commencing or sustaining a case (whether voluntary
or not) against such Trust under any bankruptcy, insolvency or similar law or
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator
or other similar official of such Trust or any substantial part of its property
or ordering the winding up or liquidation of the affairs of such Trust.

62

                    IN
WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly
executed by their respective officers thereunto duly authorized, as of the date
