                  Section 4.02      General Indemnity. (a) Claims Defined. For
the purposes of this Section 4.02, "Claims" means any and all liabilities,
obligations, losses, damages, penalties, claims, actions, suits, costs or
expenses of whatsoever kind and nature (whether or not on the basis of
negligence, strict or absolute liability or liability in tort) that may be
imposed on, incurred by, suffered by or asserted against an Indemnitee, as
defined below, and, except as otherwise expressly provided in this Section 4.02,
includes all reasonable out-of-pocket costs, disbursements and expenses

directors (the respective agents, servants, officers, employees and directors of
each of the foregoing Indemnitees, as applicable, together with such Indemnitee
and any affiliate of such Indemnitee, being collectively the "Related Indemnitee
Group" of such Indemnitee); provided that such Persons, to the extent they are
not signatories to this Agreement, have expressly agreed in writing to be bound
by the terms of this Section 4.02 prior to, or concurrently with, the making of
a Claim. If any Indemnitee fails to comply with any duty or obligation under
this Section 4.02 with respect to any Claim, such

                                      -9-

<PAGE>

Indemnitee shall not be entitled to any indemnity with respect to such Claim
under this Section 4.02 to the extent such failure was prejudicial to Company.
No holder of a Pass Through Certificate in its capacity as such holder shall be
an Indemnitee.

                 (c) Claims Indemnified. Subject to the exclusions stated in
Subsection 4.02(d), Company agrees to indemnify, protect, defend and hold
harmless on an After-Tax Basis each Indemnitee against Claims resulting from or
arising out of (a) the Operative Documents or the enforcement of any of the
terms of the Operative Documents, (b) the Aircraft, the Airframe, any Engine or
any Part, including, without limitation, with respect thereto, (i) the sale,
purchase, acceptance, non-acceptance or rejection of the Aircraft under the
Purchase Agreement or the ownership, possession, use, non-use, substitution,
airworthiness, control, maintenance, repair, operation, registration,
re-registration, de-registration, delivery, nondelivery, assignment,
abandonment, condition, sale, lease, sublease, storage, modification,
alteration, return, transfer or other disposition of the Aircraft, the Airframe,

infringement) by Company, any Permitted Lessee or any other Person, (ii) tort
liability, whether or not arising out of the negligence of any Indemnitee
(whether active, passive or imputed), (iii) death or property damage of

and (c) the offer, sale or delivery of any Equipment Notes, Pass Through
Certificates or any interest therein or represented thereby. Without limiting
the foregoing and subject to, and without duplication of, the provisions of
Section 6.01(a), Company agrees to pay the reasonable ongoing fees, and the
reasonable out-of-pocket costs and expenses actually incurred (including,
without limitation, reasonable attorney's fees and disbursements actually
incurred and, to the extent payable as provided in the Indenture, reasonable
compensation and expenses of Loan Trustee's agents actually incurred), of Loan
Trustee in connection with the transactions contemplated hereby.

                  (d)      Claims Excluded. The following are excluded from
Company's agreement to indemnify an Indemnitee under this Section 4.02:

                  (i)      any Claim to the extent such Claim is attributable to
         acts or events occurring after (x) the Lien of the Indenture has been
         discharged or (y) the transfer of possession of the Aircraft pursuant
         to Article IV of the Indenture except to the extent that such Claim is
         attributable to acts occurring in connection with the exercise of
         remedies pursuant to Section 4.02 of the Indenture following the
         occurrence and continuance of an Event of Default;

                  (ii)     any Claim to the extent such Claim is, or is
         attributable to, a Tax, except with respect to paying indemnity amounts
         on an After-Tax Basis;

                  (iii)    any Claim to the extent such Claim is attributable to
         the negligence or willful misconduct of such Indemnitee or such
         Indemnitee's Related Indemnitee Group;

                  (iv)     any Claim to the extent such Claim is attributable to
         the noncompliance by such Indemnitee or such Indemnitee's Related
         Indemnitee Group with any of the terms of, or any misrepresentation by
         an Indemnitee or its Related Indemnitee Group contained in, this
         Agreement, any other Operative Document or any Pass Through Document to

                                      -10-

<PAGE>

         which such Indemnitee or any of such Related Indemnitee Group is a
         party or any agreement relating hereto or thereto;

                  (v)      any Claim to the extent such Claim constitutes a
         Permitted Lien attributable to such Indemnitee;

                  (vi)     any Claim to the extent such Claim is attributable to
         the offer, sale, assignment, transfer, participation or other
         disposition (whether voluntary or involuntary) by or on behalf of such
         Indemnitee or its Related Indemnitee Group (other than during the
         occurrence and continuance of an Event of Default provided that any
         such offer, sale, assignment, transfer, participation or other
         disposition during the occurrence and continuation of an Event of
         Default shall not be subject to indemnification unless it is made in
         accordance with the Indenture and applicable law) of any Equipment Note
         or interest therein or Pass Through Certificate, all or any part of
         such Indemnitee's interest in the Operative Documents or the Pass
         Through Documents or any interest in the Collateral or any similar
         security;

                  (vii)    any Claim to the extent such Claim is attributable to
         (A) a failure on the part of Loan Trustee to distribute in accordance
         with this Agreement or the Indenture any amounts received and
         distributable by it hereunder or thereunder, (B) a failure on the part
         of Subordination Agent to distribute in accordance with the
         Intercreditor Agreement any amounts received and distributable by it
         thereunder or (C) a failure on the part of any Pass Through Trustee to
         distribute in accordance with the Pass Through Trust Agreement to which
         it is a party any amounts received and distributable by it thereunder;

                  (viii)   any Claim to the extent such Claim is attributable to
         the authorization or giving or withholding of any future amendments,
         supplements, waivers or consents with respect to any Operative Document
         or any Pass Through Document, other than such as have been requested by
         Company or that occur as the result of an Event of Default, or such as
         are expressly required or contemplated by the provisions of the
         Operative Documents or the Pass Through Documents;

                  (ix)     any Claim to the extent such Claim is payable or
         borne by (a) Company pursuant to any indemnification, compensation or
         reimbursement provision of any other Operative Document or any Pass
         Through Document or (b) a Person other than Company pursuant to any
         provision of any Operative Document or any Pass Through Document;

                  (x)      any Claim to the extent such Claim is an ordinary and
         usual operating or overhead expense or not an out-of-pocket expense
         actually incurred;

                  (xi)     any Claim to the extent such Claim is incurred on
         account of or asserted as a result of any "prohibited transaction"
         within the meaning of Section 406 of ERISA or Section 4975 of the Code;

                  (xii)    any Claim to the extent such Claim is attributable to
         one or more of the other aircraft financed through the offering of Pass
         Through Certificates (in the event of doubt, any Claim shall be
         allocated between the Aircraft and such other aircraft in the same
         proportion that the then outstanding Equipment Notes bear to the then
         outstanding

                                      -11-

<PAGE>

         equipment notes issued with respect to the other aircraft and held by
         Pass Through Trustees);

                  (xiii)   any Claim by an Indemnitee related to the status of
         such Indemnitee as a passenger or shipper on any of Company's aircraft
         or as a party to a marketing or promotional or other commercial
         agreement with Company unrelated to the transactions contemplated by
         the Operative Documents; and

                  (xiv)    any Claim to the extent such Claim is attributable to
         the offer or sale by an Indemnitee (or any member of such Indemnitee's
         Related Indemnitee Group) of any interest in the Aircraft, the
         Equipment Notes, the Pass Through Certificates, or any similar
         interest, in violation of the Securities Act of 1933, as amended, or
         other applicable federal, state or foreign securities laws (other than
         any thereof caused by acts or omissions of Company of any of its
         affiliates).

                  (e)      Insured Claims. In the case of any Claim indemnified
by Company hereunder that is covered by a policy of insurance maintained by
Company, each Indemnitee agrees to cooperate, at Company's expense, with the
insurers in the exercise of their rights to investigate, defend and compromise
such Claim.

                  (f)      Claims Procedure. An Indemnitee shall promptly notify
Company of any Claim as to which indemnification is sought. The failure to
provide such prompt notice shall not release Company from any of its obligations
to indemnify hereunder except to the extent that Company is prejudiced by such
failure or Company's indemnification obligations are increased as a result of
such failure (in which event Company shall not be responsible for such
additional indemnification obligations). Such Indemnitee shall promptly submit
to Company all additional information in such Indemnitee's possession to
substantiate such Claim as Company reasonably requests. Subject to the rights of
Company's insurers, Company may, at its sole cost and expense, investigate any
Claim, and may in its sole discretion defend or compromise any Claim. At
Company's expense, any Indemnitee shall cooperate with all reasonable requests
of Company in connection therewith. Such Indemnitee shall not enter into a
settlement or other compromise with respect to any Claim without the prior
written consent of Company, which consent shall not be unreasonably withheld or
delayed, unless such Indemnitee waives its right to be indemnified with respect
to such Claim. Where Company or its insurers undertake the defense of an
Indemnitee with respect to a Claim, no additional legal fees or expenses of such
Indemnitee in connection with the defense of such Claim shall be indemnified
hereunder unless such fees or expenses were incurred at the written request of
Company or such insurers. Subject to the requirements of any policy of
insurance, an Indemnitee may participate at its own expense in any judicial
proceeding controlled by Company pursuant to the preceding provisions; provided
that such party's participation does not, in the opinion of outside counsel
appointed by Company or its insurers to conduct such proceedings, interfere with
such control. Such participation shall not constitute a waiver of the
indemnification provided in this Section 4.02. Notwithstanding anything to the
contrary contained herein, Company shall not under any circumstances be liable
for the fees and expenses of more than one counsel for all Indemnitees with
respect to any one Claim. Notwithstanding anything to the contrary contained
herein, an Indemnitee shall not under any circumstances be required or deemed to
be required to contest any Claim or to assume responsibility for or control of
any judicial proceeding with respect thereto. Company will

                                      -12-

<PAGE>

provide the relevant Indemnitee with such information not within the control of
such Indemnitee, as is in Company's control or is reasonably available to
Company, which such Indemnitee may reasonably request and will otherwise
cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its
obligations under this Section.

                  (g)      Subrogation. To the extent that a Claim is in fact
paid in full by Company or its insurer, Company or such insurer (as the case may
be) shall, without any further action, be subrogated to the rights and remedies
of the Indemnitee on whose behalf such Claim was paid with respect to the
transaction or event giving rise to such Claim. Such Indemnitee shall give such
further assurances or agreements and shall cooperate with Company or such
insurer, as the case may be, to permit Company or such insurer to pursue such
rights and remedies, if any, to the extent reasonably requested by Company. So
long as no Event of Default has occurred and is continuing, if an Indemnitee
receives any payment, in whole or in part, from any party other than Company or
its insurers with respect to any Claim paid by Company or its insurers, it shall
promptly pay over to Company the amount received (but not an amount in excess of
the amount Company or any of its insurers has paid in respect of such Claim).
Any amount referred to in the preceding sentence that is payable to Company
shall not be paid to Company, or, if it has been previously paid directly to
Company, shall not be retained by Company, if at the time of such payment an
Event of Default has occurred and is continuing, but shall be paid to and held
by Loan Trustee as security for the obligations of Company under the Operative
Documents. If Company agrees, such amount payable shall be applied against
Company's obligations thereunder when and as they become due and payable. At
such time as such Event of Default is no longer continuing, such amount, to the
extent not previously so applied against Company's obligations, shall be paid to
Company.

                  (h)      No Guaranty. Nothing set forth in this Section 4.02
constitutes a guarantee by Company that the Aircraft at any time will have any
particular value, useful life or residual value.

                  (i)      Payments; Interest. Any amount payable to any
Indemnitee on account of a Claim shall be paid within 30 days after receipt by
Company of a written demand therefor from such Indemnitee accompanied by a
written statement describing in reasonable detail the Claims that are the
subject of and basis for such indemnity and the computation of the amount
payable. Any payments made pursuant to this Section 4.02 directly to an
Indemnitee or to Company, as the case may be, shall be made in immediately
available funds at such bank or to such account as is specified by the payee in
written directions to the payor or, if no such directions are given, by check of
the payor payable to the order of the payee and mailed to the payee by certified
mail, return receipt requested, postage prepaid to its address referred to in
Section 7.01. To the extent permitted by applicable law, interest at the Past
Due Rate shall be paid, on demand, on any amount or indemnity not paid when due
pursuant to this Section 4.02 until the same is paid. Such interest shall be
paid in the same manner as the unpaid amount in respect of which such interest
is due.

                  (j)      Tax deduction or credit. If, by reason of any Claim
payment made to or for the account of an Indemnitee by Company pursuant to this
Section 4.02, such Indemnitee subsequently realizes a tax deduction or credit
not previously taken into account in computing such payment, such Indemnitee
shall promptly pay to Company, but only if Company has made

                                      -13-

<PAGE>

all payments then due and owing to such Indemnitee under the Operative
Documents, an amount equal to the sum of (1) the actual reduction in Taxes
realized by such Indemnitee which such Indemnitee determines in its good faith
judgment is attributable to such deduction or credit, and (2) the actual
reduction in Taxes realized by such Indemnitee as such Indemnitee determines in
its good faith judgement is a result of any payment made by such Indemnitee
pursuant to this sentence; provided that the amount payable by such Indemnitee
pursuant to this sentence shall not exceed the sum of the amounts previously

         and the assumption agreement mentioned in clause (i) above comply with
         this Subsection 6.02(e) and that all conditions precedent herein

         on the Aircraft, modification and maintenance records at any time
         required to be maintained with respect to the Aircraft, in accordance

         United States;

                  (2)      the Warranty Rights, together with all rights,
         powers, privileges, options and other benefits of Company under the
         same;

                  (3)      all requisition proceeds with respect to the
         Aircraft or any Part thereof, and all insurance proceeds with respect
         to the Aircraft or any Part thereof, but excluding all proceeds of,
         and rights under, any insurance maintained by Company and in excess of
         that required under Section 7.06(b);

                  (4)      all moneys and securities now or hereafter paid or

to quiet enjoyment of the Aircraft, the Airframe, the Parts and the Engines,
and to possess, use, retain and control the Aircraft, the Airframe, the Parts
and the Engines and all revenues, income and profits derived therefrom and (ii)
with respect to the Warranty Rights, to exercise in Company's name all rights
and powers of the Buyer (as defined in the Purchase Agreement) under the
Warranty Rights and to retain any recovery or benefit resulting from the
enforcement of any warranty or indemnity or other obligation under the Warranty
Rights; provided, further, that notwithstanding the occurrence and continuation
of an Event of Default, Loan Trustee shall not enter into any amendment or
modification of the Purchase Agreement that would alter the rights, benefits or
obligations of Company thereunder;

                                      -2-
<PAGE>

                  TO HAVE AND TO HOLD all and singular the aforesaid property
unto Loan Trustee, and its successors and permitted assigns, in trust for the
ratable benefit and security of Noteholders, Related Noteholders and Indenture
Indemnitees, except as otherwise provided in this Indenture, including Section
2.13 and Article III, without any preference, distinction or priority of any
one Equipment Note over any other by reason of priority of time of issue, sale,
negotiation, date of maturity thereof or otherwise for any reason whatsoever,
and for the uses and purposes and in all cases and as to all property specified
in paragraphs (1) through (5) inclusive above, subject to the terms and
provisions set forth in this Indenture.

                  It is expressly agreed that notwithstanding anything herein
to the contrary, Company shall remain liable under the Purchase Agreement to
perform all of its obligations thereunder, and, except to the extent expressly
provided in any Operative Document, none of Loan Trustee, any Noteholders or
any Indenture Indemnitee shall be required or obligated in any manner to
perform or fulfill any obligations of Company under or pursuant to any
Operative Document, or have any obligation or liability under the Purchase
Agreement by reason of or arising out of the assignment hereunder, or to make
any inquiry as to the nature or sufficiency of any payment received by it, or
present or file any claim or take any action to collect or enforce the payment
of any amount that may have been assigned to it or to which it may be entitled
at any time or times.

                  Notwithstanding anything herein to the contrary (but without
in any way releasing Company from any of its duties or obligations under the
Purchase Agreement), Loan Trustee, Noteholders and Indenture Indemnitees
confirm for the benefit of Manufacturer that in exercising any rights under the
Warranty Rights, or in making any claim with respect to the Aircraft or other
goods and services delivered or to be delivered pursuant to the Purchase
Agreement, the terms and conditions of the Purchase Agreement relating to the
Warranty Rights, including, without limitation, the warranty disclaimer
provisions for the benefit of Manufacturer, shall apply to and be binding upon
Loan Trustee, Noteholders and Indenture Indemnitees to the same extent as
Company. Company hereby directs Manufacturer, so long as an Event of Default
shall have occurred and be continuing, to pay all amounts, if any, payable to
Company pursuant to the Warranty Rights directly to Loan Trustee to be held and
applied as provided herein. Nothing contained herein shall subject Manufacturer
to any liability to which it would not otherwise be subject under the Purchase
Agreement or modify in any respect the contract rights of Manufacturer
thereunder except as provided in the Manufacturer's Consent.

                  Company does hereby irrevocably constitute Loan Trustee the
true and lawful attorney of Company (which appointment is coupled with an
interest) with full power (in the name of Company or otherwise) to ask for,
require, demand and receive any and all monies and claims for monies (in each
case including insurance and requisition proceeds) due and to become due to
Company under or arising out of the Purchase Agreement (to the extent assigned
hereby), and all other property which now or hereafter constitutes part of the
Collateral, to endorse any checks or other instruments or orders in connection
therewith and to file any claims or to take any action or to institute any
proceedings which Loan Trustee may deem to be necessary or advisable in the
premises; provided that Loan Trustee shall not exercise any such rights except
during the continuance of an Event of Default. Company agrees that promptly
upon receipt thereof, to the extent required by the Operative Documents, it
will transfer to Loan Trustee any

                                      -3-
<PAGE>

and all monies from time to time received by Company constituting part of the
Collateral, for distribution by Loan Trustee pursuant to this Indenture.

                  Company does hereby warrant and represent that it has not
sold, assigned or pledged, and hereby covenants and agrees that it will not
sell, assign or pledge, so long as this Indenture shall remain in effect and
the Lien hereof shall not have been released pursuant to the provisions hereof,
any of its estate, right, title or interest hereby assigned, to any Person
other than Loan Trustee, except as otherwise provided in or permitted by any
Operative Document.

                  Company agrees that at any time and from time to time, upon
the written request of Loan Trustee, Company shall promptly and duly execute
and deliver or cause to be duly executed and delivered any and all such further
instruments and documents as Loan Trustee may reasonably deem necessary to
perfect, preserve or protect the mortgage, security interests and assignments
created or intended to be created hereby or to obtain for Loan Trustee the full
benefit of the assignment hereunder and of the rights and powers herein
granted, provided that any instrument or other document so executed by Company
will not expand any obligations or limit any rights of Company in respect of
the transactions contemplated by the Operative Documents.

                  IT IS HEREBY COVENANTED AND AGREED by and between the parties
hereto as follows:

accrued and unpaid interest on, and any other amounts due under, this Equipment
Note.]2 Notwithstanding anything to the contrary contained herein, if any date
on which a payment under this Equipment Note becomes due and payable is not a

shall be made on the next succeeding Business Day and such extension of time
shall be included in the computation of interest payable.

                  For purposes hereof, the term "Indenture" means the Indenture
and Security Agreement (N3760C), dated as of January 30, 2003, between Company
and U.S. Bank Trust National Association, as Loan Trustee ("Loan Trustee"), as
the same may be amended, supplemented or otherwise modified from time to time
in accordance with its terms. All capitalized terms used in this Equipment Note
and not defined herein, unless the context otherwise requires, shall have the
respective meanings set forth or incorporated by reference, and shall be
construed and interpreted in the manner described, in the Indenture. This
Equipment Note shall bear interest, payable on demand, at the Past Due Rate
(and not the Debt Rate) (calculated on the basis of a year of 360 days and
actual days elapsed during which such amount accrues) on any principal amount
and (to the extent permitted by applicable law) interest and any other amounts
payable hereunder not paid when due for any period during which the same is

                  There shall be maintained an Equipment Note Register for the
purpose of registering transfers and exchanges of Equipment Notes at the
Corporate Trust Office of Loan Trustee, or at the office of any successor
trustee, in the manner provided in Section 2.07 of the Indenture. The principal
amount and interest and other amounts due hereunder shall be payable in Dollars
in immediately available funds at the Corporate Trust Office of Loan Trustee,
or as otherwise provided in the Indenture. Company shall not have any
responsibility for the distribution of any such payment to Noteholder of this
Equipment Note. Each such payment shall be made on the date such payment is due
and without any presentment or surrender of this Equipment Note, except that in
the case of any final payment with respect to this Equipment Note, the
Equipment Note shall be surrendered to Loan Trustee for cancellation. The
holder hereof, by its acceptance of this Equipment Note, agrees that, except as
provided in the Indenture, including the subordination provisions referred to
below, each payment of an installment of principal amount, Make-Whole Amount,
if any, Break Amount, if any, and interest received by it hereunder shall be
applied: first, to the payment of Break Amount, if any, on this Equipment Note,
second, to the payment of accrued interest on this Equipment Note (as well as
any interest on any overdue principal amount, and, to the extent permitted by
law, any overdue Make-Whole Amount, if any, any overdue interest and other
overdue amounts hereunder) to the date of such payment; third, to the payment
of Make-Whole Amount, if any, and fourth, to the payment of the principal
amount of this Equipment Note (or portion hereof) then due.

                  This Equipment Note is one of the Equipment Notes referred to
in the Indenture which have been or are to be issued by Company pursuant to the
terms of the Indenture. The Collateral is held by Loan Trustee as security, in
part, for the Equipment Notes. The provisions of this Equipment Note are

Indenture) and the rights and obligations of the holders of, and the nature and
extent of the security for, any other Equipment Notes executed and delivered
under the Indenture, to all of which terms and conditions in the Indenture and
the Participation Agreement each holder hereof agrees by its acceptance of this
Equipment Note.

                  As provided in the Indenture and subject to certain
limitations therein set forth, this Equipment Note is exchangeable for a like
aggregate principal amount of Equipment Notes of the same Series of different
authorized denominations, as requested by the holder surrendering the same.
Prior to the due presentment for registration of transfer of this Equipment
Note, Company and Loan Trustee shall deem and treat the Person in whose name
this Equipment Note is registered on the Equipment Note Register as the
absolute owner and holder hereof for the purpose of receiving all amounts
payable with respect to this Equipment Note and for all purposes, and neither
Company nor Loan Trustee shall be affected by notice to the contrary.

                  This Equipment Note is subject to redemption as provided in
Sections 2.10 and 2.11 of the Indenture but not otherwise.

                  [The indebtedness evidenced by this Equipment Note is, to the

right of payment to the prior payment in full of the Secured Obligations (as

         Section 2.02 Issuance and Terms of Equipment Notes. The Equipment
Notes shall be dated the date of issuance thereof, shall be issued in (a) three
separate series consisting of Series G Equipment Notes, Series C Equipment
Notes and Series D Equipment Notes and (b) the maturities and principal amounts
and shall bear interest at the applicable Debt Rates specified in Schedule I.
On the Closing Date, each Series G Equipment Note, Series C Equipment Note and
Series D Equipment Note shall be issued to Subordination Agent on behalf of
each of Pass Through Trustees for the Pass Through Trusts created under the
Pass Through Trust Agreements referred to in Schedule II. The Equipment Notes
shall be issued in registered form only. The Equipment Notes shall be issued in
denominations of $1,000 and integral multiples thereof, except that one
Equipment Note of each Series may be in an amount that is not an integral
multiple of $1,000.

         Each Equipment Note shall bear interest for each Interest Period at
the Debt Rate specified for such Interest Period for the applicable Series
(calculated on the basis of a year of 360 days and actual days elapsed during
the period for which such amount accrues), payable in arrears on each Payment
Date on the unpaid principal amount thereof from time to time outstanding until
such principal amount is paid in full, as further provided in the form of
Equipment Note set forth in Section 2.01. The principal amount of each Series G
Equipment Note and each Series D Equipment Note shall be payable in
installments on the Payment Dates and in the installments equal to the
corresponding percentage of the principal amount set forth in Schedule I hereto
applicable to such Series, which shall be attached as Schedule I to such
Equipment Note. The principal amount of each Series C Equipment Note shall be
due in a single payment on January 25, 2008. Notwithstanding the foregoing, the
final payment made under each Series G Equipment Note and each Series D
Equipment Note shall be in an amount sufficient to discharge in full the unpaid
principal amount and all accrued and unpaid interest on, and any other amounts
due under, such Equipment Note. Each Equipment Note shall bear interest,
payable on demand, at the Past Due Rate (and not at the Debt Rate) (calculated
on the basis of a year of 360 days and actual days elapsed during the period
for which such amount accrues) on any principal amount and (to the extent
permitted by applicable law) interest and any other amounts payable thereunder
not paid when due for any period during which the same is overdue, in each case
for the period the same is overdue. Amounts shall be overdue under an Equipment
Note if not paid in the manner provided therein or in this Indenture when due

(whether at stated maturity, by acceleration or otherwise). Notwithstanding
anything to the contrary contained herein, if any date on which a payment
hereunder or under any Equipment Note becomes due and payable is not a Business
Day, then such payment shall not be made on such scheduled date but shall be
made on the next succeeding Business Day with the same force and effect as if
made on such scheduled date, and such extension of time shall be included in
the computation of interest payable.

         The Equipment Notes shall be executed on behalf of Company by the
manual or facsimile signature of one of its authorized officers. Equipment
Notes bearing the signatures of individuals who were at the time of execution
the proper officers of Company shall bind Company, notwithstanding that such
individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Equipment Notes or did not hold such
offices at the respective dates of such Equipment Notes. No Equipment Note
shall be secured by or entitled to any benefit under this Indenture or be valid
or obligatory for any purposes unless there appears on such Equipment Note a
certificate of authentication in the form provided herein executed by Loan
Trustee by the manual signature of one of its authorized officers, and such
certificate upon any Equipment Notes shall be conclusive evidence, and the only
evidence, that such Equipment Note has been duly authenticated and delivered
hereunder.

         Section 2.03 Method of Payment. The principal amount of, interest on,
Make-Whole Amount, if any, and, except to the extent expressly provided herein,
all other amounts due to any Noteholder under each Equipment Note or otherwise
payable hereunder shall be payable by Company in Dollars by wire transfer of
immediately available funds not later than 10:00 a.m. (New York City time) on
the due date of payment to Loan Trustee at the Corporate Trust Office for
distribution among Noteholders in the manner provided herein. Company shall not
have any responsibility for the distribution of such payment to any Noteholder.
Notwithstanding the foregoing or any provision in any Equipment Note to the
contrary, Loan Trustee will use reasonable efforts to pay or cause to be paid,
if so directed in writing by any Noteholder (with a copy to Company), all
amounts paid by Company hereunder and under such Noteholder's Equipment Note or
Equipment Notes to such Noteholder or a nominee therefor (including all amounts
distributed pursuant to Article III) by transferring, or causing to be
transferred, by wire transfer of immediately available funds in Dollars, prior
to 12:00 noon (New York City time) on the due date of payment, to an account
maintained by such Noteholder with a bank located in the continental United
States the amount to be distributed to such Noteholder, for credit to the
account of such Noteholder maintained at such bank; provided that, in the event
the Equipment Notes are not held by Subordination Agent on behalf of Pass
Through Trustees, Loan Trustee may at its option pay such amounts by check
mailed to Noteholder's address as it appears on the Equipment Note Register.
If, after its receipt of funds at the place and prior to the time specified
above in the immediately preceding sentence, Loan Trustee fails (other than as
a result of a failure of Noteholder to provide it with wire transfer
instructions) to make any such payment required to be paid by wire transfer as
provided in the immediately preceding sentence on the Business Day it receives
such funds, Loan Trustee, in its individual capacity and not as trustee, agrees
to compensate such Noteholders for loss of use of funds at the Federal Funds
Rate until such payment is made and Loan Trustee shall be entitled to any
interest earned on such funds until such payment is made. Any payment made
hereunder shall be made without any presentment or surrender of any Equipment
Note, except that, in the case of the final payment in respect of any Equipment
Note, such Equipment Note shall be surrendered to Loan Trustee for

                                     -10-
<PAGE>

cancellation. Notwithstanding any other provision of this Indenture to the
contrary, Loan Trustee shall not be required to make, or cause to be made, wire
transfers as aforesaid prior to the first Business Day on which it is
practicable for Loan Trustee to do so in view of the time of day when the funds
to be so transferred were received by it if such funds were received after 1:00
p.m. (New York City time) at the place of payment.

         Section 2.04 Withholding Taxes. Loan Trustee shall exclude and
withhold at the appropriate rate from each payment of principal amount of,
interest on, Make-Whole Amount, if any, and other amounts due hereunder or
under each Equipment Note (which exclusion and withholding shall constitute
payment of such amounts payable hereunder or in respect of such Equipment
Notes, as applicable) any and all withholding taxes applicable thereto as
required by law. Loan Trustee agrees to act as such withholding agent and, in
connection therewith, whenever any present or future taxes or similar charges
are required to be withheld with respect to any amounts payable hereunder or in
respect of the Equipment Notes, to withhold such amounts (which withholding
shall constitute payment of such amounts payable hereunder or in respect of
such Equipment Notes, as applicable) and timely pay the same to the appropriate
authority in the name of and on behalf of Noteholders, that it will file any
necessary withholding tax returns or statements when due, and that as promptly
as possible after the payment thereof it will deliver to each Noteholder (with
a copy to Company) appropriate documentation showing the payment thereof,
together with such additional documentary evidence as any such Noteholder may
reasonably request from time to time. Loan Trustee agrees to file any other
information reports it is required to file under United States law.

         Section 2.05 Application of Payments. Subject always to Section 2.13
and except as otherwise provided in Article III, in the case of each Equipment
Note, each payment of an installment of principal amount, Make-Whole Amount, if
any, Break Amount, if any, and interest paid thereon shall be applied:

                  FIRST, to the payment of Break Amount, if any, with respect
         to such Equipment Note; and

                  SECOND, to the payment of accrued interest on such Equipment
         Note (as well as any interest on any overdue principal amount and (to
         the extent permitted by law) any overdue Make-Whole Amount, if any,
         any overdue interest and any other overdue amounts thereunder) to the
         date of such payment; and

                  THIRD, to the payment of Make-Whole Amount, if any; and

                  FOURTH, to the payment of principal amount of such Equipment
         Note (or portion thereof) then due thereunder.

         Section 2.06 Termination of Interest in Collateral. No Noteholder,
Related Noteholder or Indenture Indemnitee shall, as such, have any further
interest in, or other right with respect to, the Collateral when and if (i) the
principal amount of, Make-Whole Amount, if any, and interest (including
interest on any overdue amounts) on and all other amounts due under all
Equipment Notes held by such Noteholder and all other sums then payable to such
Noteholder or Indenture Indemnitee, as the case may be, hereunder and under the

Agreement by Company, and (ii) amounts (if any) available for distribution in
accordance with clause "fourth" of Section 3.03 hereof ((i) and (ii)
collectively, "Secured Obligations") have been paid in full.

         Section 2.07 Registration, Transfer and Exchange of Equipment Notes.
Loan Trustee shall keep a register or registers (the "Equipment Note Register")
in which Loan Trustee shall provide for the registration of Equipment Notes and
the registration of transfers of Equipment Notes. No such transfer shall be
given effect unless and until registration hereunder shall have occurred. The
Equipment Note Register shall be kept at the Corporate Trust Office of Loan
Trustee. Loan Trustee is hereby appointed "Equipment Note Registrar" for the
purpose of registering Equipment Notes and transfers of Equipment Notes. A
holder of any Equipment Note intending to exchange or transfer such Equipment
Note shall surrender such Equipment Note to Loan Trustee at the Corporate Trust
Office, together with a written request from the registered holder thereof for
the issuance of a new Equipment Note of the same Series, specifying, in the
case of a surrender for transfer, the name and address of the new holder or
holders. Upon surrender for registration of transfer of any Equipment Note and
subject to satisfaction of Section 2.09, Company shall execute, and Loan
Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Equipment Notes of an equal
aggregate principal amount and of the same Series. At the option of Noteholder,
Equipment Notes may be exchanged for other Equipment Notes of the same Series
of any authorized denominations of an equal aggregate principal amount, upon
surrender of the Equipment Notes to be exchanged to Loan Trustee at the
Corporate Trust Office. Whenever any Equipment Notes are so surrendered for
exchange, Company shall execute, and Loan Trustee shall authenticate and
deliver, the Equipment Notes which Noteholder making the exchange is entitled
to receive. All Equipment Notes issued upon any registration of transfer or
exchange of Equipment Notes (whether under this Section 2.07 or under Section
2.08 or otherwise under this Indenture) shall be the valid obligations of
Company evidencing the same respective obligations, and entitled to the same
security and benefits under this Indenture, as the Equipment Notes surrendered
upon such registration of transfer or exchange. Every Equipment Note presented
or surrendered for registration of transfer shall be duly endorsed or be
accompanied by a written instrument of transfer in form satisfactory to Loan
Trustee, duly executed by Noteholder or such Noteholder's attorney duly
authorized in writing, and Loan Trustee shall require evidence satisfactory to
it as to the compliance of any such transfer with the Securities Act of 1933,
as amended, and the securities laws of any applicable state or jurisdiction.
Loan Trustee shall make a notation on each new Equipment Note of the amount of
all payments of principal amount previously made on the old Equipment Note or
Equipment Notes with respect to which such new Equipment Note is issued and the
date to which interest on such old Equipment Note or Equipment Notes has been
paid. Principal, interest and all other amounts shall be deemed to have been
paid on such new Equipment Note to the date on which such amounts have been
paid on such old Equipment Note. Company shall not be required to exchange any
surrendered Equipment Notes as provided above (a) during the ten-day period
preceding the due date of any payment on such Equipment Note or (b) that has
been called for redemption. Company and Loan Trustee shall in all cases deem
and treat the Person in whose name any Equipment Note has been issued and
registered on the Equipment Note Register as the absolute owner and Noteholder
of such Equipment Note for the purpose of receiving payment of all amounts
payable with respect to such Equipment Note and for all other purposes, and
neither Company nor Loan Trustee shall be affected by any notice to the
contrary. Loan Trustee will promptly notify Company of each registration of a

notice from Company, is one month prior to the escheat period provided under
applicable state law) shall be paid to Company. Noteholders of any outstanding
Equipment Notes shall thereafter, as unsecured general creditors, look only to
Company for payment thereof, and all liability of Loan Trustee with respect to
such trust money shall thereupon cease. Loan Trustee, before being required to
make any such repayment, may at the expense of Company cause to be mailed to
each such Noteholder notice that such money remains unclaimed. After a date

of any single Equipment Note held by it, and (y) to give different Directions
with respect to different portions of the principal amount of any single
Equipment Note held by it. Any Direction given by Subordination Agent at any

of all of the Equipment Notes issued and then outstanding hereunder shall be
deemed to have been given by a Majority in Interest of Noteholders.

of the notice of cancellation or lapse referred to in Section 7.06 or (ii) the
date such insurance is not in effect as to Loan Trustee;

<PAGE>

         (d)      Company fails to perform or observe any other covenant,
condition or agreement to be performed or observed by it under any Operative
Document, and such failure continues unremedied for a period of 60 days after
receipt by Company of written notice thereof from Loan Trustee or any
Noteholder; provided that, if such failure is capable of being remedied, no
such failure shall constitute an Event of Default for a period of one year
after such notice is received by Company so long as Company is diligently
proceeding to remedy such failure;

         (e)      any representation or warranty made by Company in any
Operative Document was incorrect in any material respect at the time made, and
such incorrectness continues to be material to the transactions contemplated
hereby and continues unremedied for a period of 60 days after receipt by
Company of written notice thereof from Loan Trustee; provided that, if such
incorrectness is capable of being remedied, no such incorrectness shall
constitute an Event of Default for a period of one year after such notice is
received by Company so long as Company is diligently proceeding to remedy such
incorrectness;

         (f)      Company consents to the appointment of or the taking of
possession by a receiver, trustee or liquidator in respect of a substantial
part of its property, admits in writing its inability to pay its debts
generally as they come due or makes a general assignment for the benefit of its
creditors;

         (g)      Company files a voluntary petition in bankruptcy or a
voluntary petition or an answer seeking reorganization, liquidation or other
relief as a debtor in a case under any bankruptcy laws or insolvency laws (as
in effect at such time) or an answer admitting the material allegations of a
petition filed against Company as a debtor in any such case, or Company as a
debtor seeks relief by voluntary petition, answer or consent, under the
provisions of any other bankruptcy or other similar law providing for the
reorganization or winding-up of corporations (as in effect at such time), or
Company seeks an agreement, composition, extension or adjustment with its
creditors under such laws;

         (h)      an order, judgment or decree is entered by any court of

property, or granting any other relief in respect of Company as a debtor under
any bankruptcy laws or insolvency laws (as in effect at such time), and any

undismissed, unstayed or unvacated for a period of 90 days after the date of
entry thereof;

         (i)      a petition against Company as a debtor in a case under the
federal bankruptcy laws or other insolvency laws (as in effect at such time) is
filed and not withdrawn or dismissed within 90 days thereafter, or if, under
the provisions of any law providing for reorganization or winding-up of
corporations that may apply to Company, any court of competent jurisdiction
assumes jurisdiction, custody or control of Company or of any substantial part
of its property and such jurisdiction, custody or control remains in force
unrelinquished, unstayed or unterminated for a period of 90 days; or

Amount, if any, or interest on, any Equipment Note or any Related Equipment
Note has not been paid in full on the Final Payment Date;

provided, however, that notwithstanding anything to the contrary contained in
this Section 4.01, any failure of Company to perform or observe any covenant,
condition or agreement shall not constitute an Event of Default if such failure
arises by reason of an event referred to in the definition of "Event of Loss"
so long as Company is continuing to comply with all of the terms of Section
7.05.

         Section 4.02 Remedies. (a) If an Event of Default has occurred and is
continuing and so long as the same shall continue unremedied, then and in every
such case Loan Trustee may, and upon the written instructions of a Majority in
Interest of Noteholders, Loan Trustee shall, do one or more of the following to
the extent permitted by, and subject to compliance with the requirements of,
applicable law then in effect (provided, however, that during any period the
Airframe or any Engine is subject to the CRAF Program and is in possession of
or being operated under the direction of the United States government or an
agency or instrumentality of the United States, Loan Trustee shall not, on
account of any Event of Default, be entitled to exercise or pursue any of the
powers, rights or remedies described in this Section 4.02 in such manner as to
limit Company's control under this Indenture (or any Permitted Lessee's control
under any Lease) of the Airframe or such Engine, unless at least 60 days' (or
such lesser period as may then be applicable under the Military Airlift Command
Program of the United States government) prior written notice of default
hereunder has been given by Loan Trustee by registered or certified mail to
Company (and any such Permitted Lessee) with a copy addressed to the
Contracting Office Representative or other appropriate person for the Military
Airlift Command of the United States Air Force under any contract with Company
(or such Permitted Lessee) relating to the Aircraft):

                  (i)      declare by written notice to Company all the
         Equipment Notes to be due and payable, whereupon the aggregate unpaid
         principal amount of all Equipment Notes then outstanding, together
         with accrued but unpaid interest thereon, Break Amount, if any, with
         respect thereto, and other amounts due thereunder (but without
         Make-Whole Amount), shall immediately become due and payable without
         presentment, demand, protest or notice, all of which are hereby
         waived; provided that if an Event of Default referred to in
         Subsections 4.01(f), (g), (h) or (i) has occurred and is continuing,
         then and in every such case the unpaid principal amount then
         outstanding, together with accrued but unpaid interest, Break Amount,
         if any, with respect thereto, and all other amounts due thereunder
         (but without Make-Whole Amount) shall immediately and without further
         act become due and payable without presentment, demand, protest or
         other notice, all of which are hereby waived; and, following such
         declaration or deemed declaration:

                  (ii)     (A) cause Company, upon the demand by notice of Loan
         Trustee, at Company's expense, to deliver promptly, and Company shall
         deliver promptly, all or such part of the Airframe or any Engine as
         Loan Trustee so demands to Loan Trustee or its order, or, if Company
         has failed to so deliver the Airframe or any Engine after such demand,
         Loan Trustee, at its option, may enter upon the premises where all or
         any part of the Airframe or any Engine are located and take immediate
         possession of and remove the same together with any engine which is
         not an Engine but which is installed on the

                                     -25-
<PAGE>

         Airframe, subject to all of the rights of the owner, lessor, lienor or
         secured party of such engine; provided that the Airframe with an
         engine (which is not an Engine) installed thereon may be flown or
         returned only to a location within the continental United States, and
         such engine shall be held for the account of any such owner, lessor,
         lienor, secured party or, if such engine is owned by Company, may at
         the option of Company with the consent of Loan Trustee (which will not
         be unreasonably withheld) or at the option of Loan Trustee with the
         consent of Company (which will not be unreasonably withheld), be
         exchanged with Company for an Engine in accordance with the provisions
         of Section 7.05(b); (B) sell all or any part of the Airframe and any
         Engine at public or private sale, whether or not Loan Trustee at the
         time has possession thereof, as Loan Trustee may determine, or
         otherwise dispose of, hold, use, operate, lease to others or keep idle
         all or any part of the Airframe or such Engine as Loan Trustee, in its
         sole discretion, determines, all free and clear of any rights or
         claims of Company, and the proceeds of such sale or disposition shall
         be applied as set forth in Section 3.03; or (C) exercise any other
         remedy of a secured party under the Uniform Commercial Code of the
         State of New York (whether or not in effect in the jurisdiction in
         which enforcement is sought).

                  Upon every such taking of possession of Collateral under this
Section 4.02, Loan Trustee may, from time to time, at the expense of the
Collateral, make all such expenditures for maintenance, insurance, repairs,
alterations, additions and improvements to and of the Collateral as it deems
necessary to cause the Collateral to be in such condition as required by the
provisions of this Indenture. In each such case, Loan Trustee may maintain,
use, operate, store, insure, lease, control, manage or dispose of the
Collateral and may exercise all rights and powers of Company relating to the
Collateral as Loan Trustee reasonably deems best, including the right to enter
into any and all such agreements with respect to the maintenance, use,
operation, storage, insurance, leasing, control, management or disposition of
the Collateral or any part thereof as Loan Trustee may reasonably determine;
and Loan Trustee shall be entitled to collect and receive directly all tolls,
rents, revenues, issues, income, products and profits of the Collateral and
every part thereof without prejudice, however, to the rights of Loan Trustee
under any provision of this Indenture to collect and receive all cash held by,
or required to be deposited with Loan Trustee hereunder. Such tolls, rents,
revenues, issues, income, products and profits shall be applied to pay the
expenses of the use, operation, storage, insurance, leasing, control,
management or disposition of the Collateral, and of all maintenance, repairs,
replacements, alterations, additions and improvements, and to make all payments
that Loan Trustee is required or elects to make, if any, for Taxes, insurance
or other proper charges assessed against or otherwise imposed upon the
Collateral or any part thereof, and all other payments which Loan Trustee is
required or expressly authorized to make under any provision of this Indenture,
as well as just and reasonable compensation for the services of Loan Trustee,
and shall otherwise be applied in accordance with Article III. If an Event of
Default has occurred and is continuing and the Equipment Notes either have been
accelerated pursuant to this Section 4.02 or have become due at maturity and
Loan Trustee is entitled to exercise rights hereunder, at the request of Loan
Trustee, Company shall promptly execute and deliver to Loan Trustee such
instruments of title and other documents as Loan Trustee reasonably deems
necessary or advisable to enable Loan Trustee or an agent or representative
designated by Loan Trustee, at such time or times and place or places as Loan
Trustee specifies, to obtain possession of all or any part of the Collateral to
which Loan Trustee at the time is entitled hereunder. If Company for any reason
fails to execute and deliver such instruments and documents after such request
by Loan Trustee, Loan Trustee

                                     -26-
<PAGE>

may obtain a judgment conferring on Loan Trustee the right to immediate
possession and requiring Company to execute and deliver such instruments and
documents to Loan Trustee, to the entry of which judgment Company hereby
specifically consents to the fullest extent it may lawfully do so. All actual
and reasonable expenses of obtaining such judgement or of pursuing, searching
for and taking such property shall, until paid, be secured by the Lien of this
Indenture.

         (b)      Loan Trustee shall give Company at least 30 days' prior
written notice of any public sale or of the date on or after which any private
sale will be held, which notice Company hereby agrees to the extent permitted
by applicable law is reasonable notice. Any Noteholder or Noteholders shall be
entitled to bid for and become the purchaser of any Collateral offered for sale
pursuant to this Section 4.02 and to credit against the purchase price bid at
such sale by such Noteholders all or any part of the unpaid amounts owing to
such Noteholders under the Operative Documents and secured by the Lien of this
Indenture (but only to the extent that such purchase price would have been paid
to such Noteholders pursuant to Article III if such purchase price were paid in
cash and the foregoing provision of this Section 4.02(b) were not given
effect). Loan Trustee may exercise such right without possession or production
of the Equipment Notes or proof of ownership thereof, and as a representative
of Noteholders may exercise such right without notice to Noteholders as parties
to any suit or proceeding relating to the foreclosure of any Collateral.
Company may also bid for and become the purchaser of any Collateral offered for
sale pursuant to this Section 4.02.

         (c)      To the extent permitted by applicable law, while an Event of
Default has occurred and is continuing, Company irrevocably appoints Loan
Trustee the true and lawful attorney-in-fact of Company (which appointment is
coupled with an interest) in its name and stead and on its behalf, for the
purpose of effectuating any sale, assignment, transfer or delivery for the
enforcement of the Lien of this Indenture, whether pursuant to foreclosure or
power of sale, or otherwise, to execute and deliver all such bills of sale,
assignments and other instruments as may be necessary or appropriate, with full
power of substitution, Company hereby ratifying and confirming all that such
attorney or any substitute does by virtue hereof in accordance with applicable
law; provided that if so requested by Loan Trustee or any purchaser, Company
shall ratify and confirm any such sale, assignment or transfer of delivery, by
executing and delivering to Loan Trustee or such purchaser all bills of sale,
assignments, releases and other proper instruments to effect such ratification
and confirmation as may be designated in any such request.

         (d)      At any time after Loan Trustee has declared the unpaid
principal amount of all Equipment Notes then outstanding to be due and payable
and prior to the sale of any part of the Collateral pursuant to this Article
IV, a Majority in Interest of Noteholders, by written notice to Company and
Loan Trustee, may rescind and annul such declaration, whether made by Loan
Trustee on its own accord or as directed, and its consequences if: (i) there
has been paid to or deposited with Loan Trustee an amount sufficient to pay all
overdue installments of principal amount of, and interest on, the Equipment
Notes, and all other amounts owing under the Operative Documents, that have
become due otherwise than by such declaration of acceleration and (ii) all
other Events of Default, other than nonpayment of principal amount or interest
on the Equipment Notes that have become due solely because of such
acceleration, have been either cured or waived; provided, that no such
recission or annulment shall extend to or affect any subsequent default or
Event of Default or impair any right consequent thereon.

                                     -27-

         (e)      Notwithstanding anything contained herein, so long as Pass
Through Trustee under any Pass Through Trust Agreement or Subordination Agent
on its behalf is a Noteholder, Loan Trustee will not be authorized or empowered
to acquire title to any Collateral or take any action with respect to any
Collateral so acquired by it if such acquisition or action would cause any Pass
Through Trust to fail to qualify as a "grantor trust" for federal income tax
purposes.

         Section 4.03 Remedies Cumulative. To the extent permitted under
applicable law, each and every right, power and remedy specifically given to
Loan Trustee herein or otherwise in this Indenture shall be cumulative and
shall be in addition to every other right, power and remedy specifically given
herein or now or hereafter existing at law, in equity or by statute, and each
and every right, power and remedy whether specifically given herein or
otherwise existing may be exercised from time to time and as often and in such
order as may be deemed expedient by Loan Trustee, and the exercise or the
beginning of the exercise of any 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 Loan Trustee in the exercise of any
right, remedy or power or in the pursuance of any remedy shall, to the extent
permitted by applicable law, impair any such right, power or remedy or be
construed to be a waiver of any default on the part of Company or to be an
acquiescence therein.

         Section 4.04 Discontinuance of Proceedings. In case Loan Trustee has
instituted any proceedings to enforce any right, power or remedy under this
Indenture by foreclosure, entry or otherwise, and such proceedings have been
discontinued or abandoned for any reason or have been determined adversely to
Loan Trustee, then and in every such case Company and Loan Trustee shall,
subject to any determination in such proceedings, be restored to their former
positions and rights hereunder with respect to the Collateral, and all rights,
remedies and powers of Loan Trustee shall continue as if no such proceedings
had been undertaken (but otherwise without prejudice).

         Section 4.05 Waiver of Past Defaults. Upon written instruction from a
Majority in Interest of Noteholders, Loan Trustee shall waive any past default
hereunder and its consequences, and upon any such waiver such default shall
cease to exist and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of the Operative Documents, but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon; provided, however, that in the absence of written
instructions from each of the affected Noteholders, Loan Trustee shall not
waive any default (i) in the payment of the principal amount, Make-Whole
Amount, if any, Break Amount, if any, or interest due under any Equipment Note
then outstanding (other than with the consent of the holder thereof), or (ii)
in respect of a covenant or provision hereof which, under Article IX, cannot be
modified or amended without the consent of each such affected Noteholder.

         Section 4.06 Noteholders May Not Bring Suit Except Under Certain
Conditions. A Noteholder of any Series shall not have the right to institute
any suit, action or proceeding at law or in equity or otherwise with respect to
this Indenture for the appointment of a receiver or for the enforcement of any
other remedy under this Indenture, unless:

                                     -28-
<PAGE>

                  (1)      such Noteholder previously shall have given written
         notice to Loan Trustee of a continuing Event of Default;

                  (2)      A Majority in Interest of Noteholders shall have
         requested Loan Trustee in writing to institute such action, suit or
         proceeding and shall have offered to Loan Trustee indemnity as
         provided in Section 5.03;

                  (3)      Loan Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and

                  (4)      no direction inconsistent with such written request
         shall have been given to Loan Trustee during such 60-day period by a
         Majority in Interest of Noteholders.

                  Except to the extent provided in the Intercreditor Agreement
or in any Indenture Supplement, it is understood and intended that no one or
more of Noteholders of any Series shall have any right in any manner whatsoever
hereunder or under the Indenture Supplement or under the Equipment Notes of
such Series to (i) surrender, impair, waive, affect, disturb or prejudice any
Collateral, or the Lien of the Indenture on any Collateral, or the rights of
Noteholders of such Series, (ii) obtain or seek to obtain priority over or
preference with respect to any other such Noteholder of such Series or (iii)
enforce any right under this Indenture, except in the manner provided in this
Indenture and for the equal, ratable and common benefit of all Noteholders of
such Series subject to the provisions of this Indenture.

         Section 4.07 Appointment of a Receiver. Loan Trustee shall, as a
matter of right, be entitled to the appointment of a receiver (who may be Loan
Trustee or any successor or nominee thereof) for all or any part of the
Collateral, whether such receivership be incidental to a proposed sale of the
Collateral or the taking of possession thereof or otherwise, and Company hereby
consents to the appointment of such a receiver and will not oppose any such
appointment. Any receiver appointed for all or any part of the Collateral shall
be entitled to exercise all the rights and powers of Loan Trustee with respect
to the Collateral.

         Section 4.08 Rights of Noteholders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Noteholder to receive
payment of principal of, and premium, if any, and interest on an Equipment Note
on or after the respective due dates expressed in such Equipment Note, shall
not be impaired or affected without the consent of such Noteholder.

                             DUTIES OF LOAN TRUSTEE

         Section 5.01 Notice of Event of Default. If Loan Trustee has knowledge
of an Event of Default or of a default arising from a failure by Company to pay
when due any payment of principal amount, interest on, Break Amount, if any, or
Make-Whole Amount, if any, due and payable under any Equipment Note, Loan
Trustee shall promptly give notice thereof to Company, Policy Provider, the
Primary Liquidity Provider and each Noteholder. Subject to the

                                     -29-
<PAGE>

terms of Sections 4.02, 4.05, 5.02 and 5.03, Loan Trustee shall take such
action, or refrain from taking such action, with respect to such default or
Event of Default (including with respect to the exercise of any rights or
remedies hereunder) as Loan Trustee is instructed in writing by a Majority in
Interest of Noteholders. Subject to the provisions of Section 5.03, if Loan
Trustee does not receive instructions as above provided within 20 Business Days
after giving notice of such default or Event of Default to Noteholders, Loan
Trustee may, subject to instructions thereafter received pursuant to the
preceding provisions of this Section 5.01, take such action, or refrain from
taking such action with respect to such default or Event of Default as it
reasonably determines to be advisable in the best interests of Noteholders, but
shall be under no duty to take or refrain from taking any action. It shall use
the same degree of care and skill in connection therewith as a prudent person
would use under the circumstances in the conduct of his or her own affairs.
Loan Trustee may not sell the Airframe or any Engine without the consent of a
Majority in Interest of Noteholders.

         For all purposes of this Indenture, in the absence of actual
knowledge, Loan Trustee shall not be deemed to have knowledge of a default or
an Event of Default unless notified in writing by Company or one or more
Noteholders; and "actual knowledge" (as used in the foregoing clause) of Loan
Trustee shall mean actual knowledge of an officer in the Corporate Trust
Division of Loan Trustee; provided, however, that Loan Trustee is deemed to
have actual knowledge of (i) the failure of Company to pay any principal amount
of, or interest on, the Equipment Notes directly to Loan Trustee when the same
shall become due or (ii) the failure of Company to maintain insurance as
required under Section 7.06 if Loan Trustee receives written notice thereof
from an insurer or insurance broker.

         Section 5.02 Action upon Instructions; Certain Rights and Limitations.
Subject to the terms of Article IV and this Article V, upon the written
instructions at any time of a Majority in Interest of Noteholders, Loan Trustee
shall promptly (i) give such notice, direction, consent, waiver or approval or
exercise such right, remedy or power hereunder in respect of all or any part of
the Collateral or (ii) take such other action, as is specified in such
instructions.

         Loan Trustee will cooperate with Company in connection with the
recording, filing, re-recording and refiling of the Indenture and any
supplements to it and any financing statements or other documents as is
necessary to maintain the perfection hereof or otherwise protect the security
interests created hereby. Loan Trustee shall furnish to Company upon request
such information and copies of such documents as Loan Trustee may have and as
are necessary for Company to perform its duties under Article II hereof.

         Section 5.03 Indemnification. Loan Trustee shall not be required to
take any action or refrain from taking any action under Sections 5.01 (other
than the first sentence thereof) or 5.02 or Article IV unless it shall have
received indemnification against any risks incurred in connection therewith in
form and substance reasonably satisfactory to it, including, without
limitation, adequate advances against costs that may be incurred by it in
connection therewith. Loan Trustee shall not be required to take any action
under Section 5.01 (other than the first sentence thereof) or 5.02 or Article
IV, nor shall any other provision of any Operative Document be deemed to impose
a duty on Loan Trustee to take any action, if Loan Trustee shall have been
advised by outside counsel that such action is contrary to the terms hereof or
is otherwise contrary to law.

                                     -30-

         Section 5.04 No Duties Except as Specified in Indenture or
Instructions. Loan Trustee shall not have any duty or obligation to manage,
control, lease, use, sell, operate, store, dispose of or otherwise deal with
the Aircraft or any other part of the Collateral, or to otherwise take or
refrain from taking any action under, or in connection with, this Indenture,
except as expressly provided by the terms of this Indenture or the
Participation Agreement or as expressly provided in written instructions
received pursuant to the terms of Section 5.01 or 5.02; and no implied duties
or obligations shall be read into this Indenture against Loan Trustee.

         Section 5.05 No Action Except under Indenture or Instructions. Loan
Trustee will not manage, control, use, sell, lease, operate, store, dispose of
or otherwise deal with the Aircraft or any other part of the Collateral except
in accordance with the powers granted to, or the authority conferred upon, Loan
Trustee pursuant to this Indenture and in accordance with the express terms
hereof.

         Section 5.06 Investment of Amounts Held by Loan Trustee. Any monies
(including for the purpose of this Section 5.06 any cash deposited with Loan
Trustee by Company, any cash received by Loan Trustee pursuant to Sections
7.05(c) or 7.06(d) or otherwise) or Permitted Investments purchased by the use
of such cash pursuant to this Section 5.06 or any cash constituting the
proceeds of the maturity, sale or other disposition of any Permitted
Investments) held by Loan Trustee hereunder as part of the Collateral, until
paid out by Loan Trustee as herein provided, (i) subject to clause (ii) below,
may be carried by Loan Trustee on deposit with itself or on deposit to its
account with any bank, trust company or national banking association
incorporated or doing business under the laws of the United States or one of
the states thereof having combined capital and surplus and retained earnings of
a least $100,000,000, and Loan Trustee shall not have any liability for
interest upon any such monies except as otherwise agreed in writing with
Company, or (ii) at any time and from time to time, so long as no Event of
Default shall have occurred and be continuing, at the request of Company, shall
be invested and reinvested in Permitted Investments as specified in such
request (if such investments are reasonably available for purchase) and sold,
in any case at such prices, including accrued interest or its equivalent, as
are set forth in such request, and such Permitted Investments shall be held by
Loan Trustee in trust as part of the Collateral until so sold; provided that
Company shall upon demand pay to Loan Trustee the amount of any loss realized
upon maturity, sale or other disposition of any such Permitted Investment and,
so long as no Event of Default or Payment Default shall have occurred and be
continuing, Company shall be entitled to receive from Loan Trustee, and Loan
Trustee shall promptly pay to Company, any profit, income, interest, dividend
or gain realized upon maturity, sale or other disposition of any Permitted
Investment. If an Event of Default or Payment Default shall have occurred and
be continuing, any net income, profit, interest, dividend or gain realized upon
maturity, sale or other disposition of any Permitted Investment shall be held
as part of the Collateral and shall be applied by Loan Trustee at the same
time, on the same conditions and in the same manner as the amounts in respect
of which such income, profit, interest, dividend or gain was realized are
required to be distributed in accordance with the provisions hereof pursuant to
which such amounts were required to be held. Loan Trustee shall not be
responsible for any losses on any investments or sales of Permitted Investments
made pursuant to the procedure specified in this Section 5.06 other than by
reason of its willful misconduct or negligence. If any moneys or investments
are held by Loan Trustee solely because an Event of Default has occurred and is
continuing and such moneys or investments have been held for a period of 90
consecutive days during which such

                                     -31-
<PAGE>

Event of Default is continuing without any remedial action being taken by Loan
Trustee (it being expressly understood that such remedial action includes any
declaration of acceleration of the Equipment Notes) in respect of such Event of
Default pursuant to Section 4.02 hereof, and provided that there is no stay,
moratorium or injunction in effect preventing the taking of such action, then,
notwithstanding any other provision of the Operative Documents, all such moneys
and investments held by Loan Trustee shall be released to Company on such 90th
day, or on the next Business Day after such 90th day.

                                  ARTICLE VI

trusts and duties hereby created and applicable to it and agrees to perform
such duties, but only upon the terms of this Indenture and agrees to receive,
handle and disburse all monies received by it as Loan Trustee constituting part
of the Collateral in accordance with the terms hereof. U.S. Bank shall have no
liability hereunder except (a) for its own willful misconduct or negligence,
(b) as provided in the fourth sentence of Section 2.03 and the penultimate
sentence of Section 5.06, (c) for liabilities that may result from the
inaccuracy of any representation or warranty of U.S. Bank in the Participation
Agreement or expressly made hereunder and (d) as otherwise expressly provided
in the Operative Documents.

         Section 6.02 Absence of Certain Duties. Except in accordance with
written instructions furnished pursuant to Sections 5.01, 5.02 or 6.06, and
except as provided in, and without limiting the generality of, Sections 5.02,

of the Aircraft or any recording or filing of this Indenture or any other
document, or to see to the maintenance of any such registration, recording or
filing, (b) to see to any insurance on the Aircraft or to effect or maintain
any such insurance, whether or not Company is in default with respect thereto,
(c) to confirm, verify or inquire into the failure to receive any financial
statements of Company or (d) to inspect the Aircraft at any time or ascertain
or inquire as to the performance or observance of any of Company's covenants
hereunder with respect to the Aircraft.

         Section 6.03 No Representations or Warranties as to the Documents.
Except as provided in Article 5 of the Participation Agreement, Loan Trustee
shall not be deemed to have made any representation or warranty as to the
validity, legality or enforceability of any Operative Document or any other
document or instrument, or as to the correctness of any statement (other than a
statement by Loan Trustee) contained herein or therein, except that Loan
Trustee hereby represents and warrants that each of said specified documents to
which it is a party has been or will be duly executed and delivered by one of
its officers who is and will be duly authorized to execute and deliver such
document on its behalf.

         Section 6.04 No Segregation of Monies; No Interest. Subject to Section
5.06 hereof, all moneys received by Loan Trustee shall, until used or applied
as herein provided, be held in trust for the purposes for which they were
received, but need not be segregated from other funds except to the extent
required by mandatory provisions of law, and neither Loan Trustee nor any agent
of Loan Trustee shall be under any liability for interest on any moneys

                                     -32-

that any portion thereof paid or applied pursuant hereto shall be identifiable
as to the source thereof.

         Section 6.05 Reliance; Agents; Advice of Counsel. Loan Trustee shall
not incur any liability to anyone in acting upon any signature, instrument,
notice, resolution, request, consent, order, certificate, report, opinion, bond
or other document or paper reasonably believed by it to be genuine and
reasonably believed by it to be signed by the proper party or parties. Loan
Trustee may accept a copy of a resolution of the Board of Directors of any
party to the Participation Agreement, certified by the Secretary or an
Assistant Secretary of such party as duly adopted and in full force and effect,
as conclusive evidence that such resolution has been duly adopted and that the
same is in full force and effect. As to any fact or matter the manner of
ascertainment of which is not specifically described herein, Loan Trustee may
for all purposes hereof rely on a certificate, signed by a duly authorized
officer of Company, as to such fact or matter, and such certificate shall
constitute full protection to Loan Trustee for any action taken or omitted to
be taken by it in good faith in reliance thereon. In the administration of the
trusts hereunder, Loan Trustee may, (a) execute any of the trusts or powers
hereof and perform its powers and duties hereunder directly or through agents
(including paying agents or registrars) or attorneys, and (b) at the expense of
the Collateral, consult with counsel, accountants and other skilled Persons to
be selected and retained by it. Loan Trustee shall not be liable for anything
done, suffered or omitted in good faith by it in accordance with the advice or
opinion of any such counsel, accountants or other skilled Persons acting within
such counsel's, accountants' or Person's area of competence (so long as Loan
Trustee shall have exercised reasonable care and judgment in selecting such
Persons).

         Section 6.06 Instructions from Noteholders. In the administration of
the trusts created hereunder, Loan Trustee shall have the right to seek
instructions from a Majority in Interest of Noteholders should any provision of
this Indenture appear to conflict with any other provision herein or any other
Operative Document or Pass Through Document or should Loan Trustee's duties or
obligations hereunder be unclear, and Loan Trustee shall incur no liability in
refraining from acting until it receives such instructions. Loan Trustee shall
be fully protected for acting in accordance with any instructions received
under this Section 6.06.

         conditional sale or other security agreement under circumstances where
         neither clause (v) nor clause (vi) of this Section 7.02(a) is
         applicable; provided that such installation shall be deemed an Event
         of Loss with respect to such Engine, and Company shall comply with

         entered into; and

                  (ix)     lease any Engine or the Airframe and Engines to (A)
         any foreign air carrier other than those set forth in clause (B), (B)
         any foreign air carrier that is at the inception of the lease based in
         and a domiciliary of a country listed in Exhibit B hereto, (C) the
         manufacturer of the Airframe or any Engine (either directly or through
         an affiliate) and (D) any foreign air carrier consented to in writing
         by Loan Trustee with the consent of a Majority in Interest of
         Noteholders; provided that (v) no Event of Default exists at the time
         such lease is entered into, (w) in the case of a lease to a foreign
         air carrier under clause (A) above, Loan Trustee receives at the time
         of such lease (1) written confirmation from each of the Rating
         Agencies that such lease would not result in a reduction of the rating
         for any class of Pass Through Certificates below the then current
         rating for such class of Pass Through Certificates or a withdrawal or
         suspension of the rating of any class of Pass Through Certificates,
         without regard to the Policy (as defined in the Policy Provider
         Agreement) and (2) an opinion of counsel to Company (such counsel to
         be reasonably satisfactory to Loan Trustee) to the effect that there
         exist no possessory rights in favor of the lessee under the laws of
         such lessee's country which would, upon bankruptcy or insolvency of or
         other default by Company and assuming at such time such lessee is not
         insolvent or bankrupt, prevent the taking of possession of any such
         Engine or the Airframe and any such Engine by Loan Trustee in
         accordance with and when permitted by the terms of Section 4.02 upon
         the exercise by Loan Trustee of its remedies under Section 4.02, (x)
         in the case of a lease to any foreign air carrier (other than a
         foreign air carrier principally based in Taiwan), the United States
         maintains normal diplomatic relations with the country in which such
         foreign air carrier is based at the time such lease is entered into
         and in the case of a lease to a foreign air carrier principally based
         in Taiwan, the United States maintains diplomatic relations with
         Taiwan at least as good as those on the Closing Date, (y) in the case
         of a lease to any foreign air carrier, Company furnishes Loan Trustee
         with a certificate from a Responsible Officer of Company certifying
         that there exist no possessory rights in favor of such lessee under
         the laws of such lessee's country which would, upon bankruptcy or
         insolvency of or other

                                     -36-
<PAGE>

         default by Company, and assuming at such time such lessee is not
         insolvent or bankrupt, prevent the taking of possession of any such
         Engine or the Airframe and any such Engine by Loan Trustee in
         accordance with and when permitted by the terms of Section 4.02 upon
         the exercise by Loan Trustee of its remedies under Section 4.02, and
         (z) in the case of any lease to a foreign air carrier, such carrier is
         not then subject to any bankruptcy, insolvency, liquidation,
         reorganization, dissolution or similar proceeding and shall not have
         substantially all of its property in the possession of any liquidator,
         trustee, receiver or similar person;

provided that the rights of any lessee or other transferee who receives
possession of the Aircraft, the Airframe or any Engine by reason of a transfer
permitted by this Section 7.02(a) (other than the transfer of an Engine which
is deemed an Event of Loss) shall be subject and subordinate to, and any
permitted lease shall be made expressly subject and subordinate to, all the
terms of this Indenture, including Loan Trustee's rights to repossess pursuant
to Section 4.02 and to avoid such lease upon such repossession, and Company
shall remain primarily liable hereunder for the performance and observance of
all of the terms and conditions of this Indenture to the same extent as if such
lease or transfer had not occurred, any such lease shall include appropriate
provisions for the maintenance and insurance of the Aircraft, the Airframe or
such Engine, and no lease or transfer of possession otherwise in compliance
with this Section shall (x) result in any registration or re-registration of
the Aircraft except to the extent permitted in Section 7.02(e) or the
maintenance, operation or use thereof that does not comply with Section 7.02(b)
and (c) or (y) permit any action not permitted to be taken by Company with
respect to the Aircraft hereunder. Company shall promptly notify Loan Trustee
and the Rating Agencies of the existence of any such lease with a term in
excess of one year.

         Loan Trustee, each Noteholder by acceptance of an Equipment Note, and
each Related Noteholder by acceptance of a Related Equipment Note agrees, for
the benefit of Company (and any Permitted Lessee) and for the benefit of the
lessor or secured party of any airframe or engine leased to Company (or any
Permitted Lessee) or purchased or owned by Company (or any Permitted Lessee)
subject to a conditional sale or other security agreement, that Loan Trustee,
Noteholders and Related Noteholders will not acquire or claim, as against
Company (or any Permitted Lessee) or such lessor or secured party, any right,
title or interest in: (A) any engine or engines owned by Company (or any
Permitted Lessee) or by the lessor under such lease or subject to a security
interest in favor of the secured party under such conditional sale or other
security agreement as the result of such engine or engines being installed on
the Airframe, or (B) any airframe owned by Company (or any Permitted Lessee) or
by the lessor under such lease or subject to a security interest in favor of
the secured party under such conditional sale or other security agreement as
the result of any Engine being installed on such airframe.

         Loan Trustee acknowledges that any "wet lease" or other similar
arrangement under which Company (or any Permitted Lessee) maintains operational
control of the Aircraft does not constitute a delivery, transfer or
relinquishment of possession for purposes of this Section 7.02(a).

         (b)      Operation and Use. Company agrees that the Aircraft will not
be maintained, used or operated in violation of any law, rule or regulation of
any government of any

                                     -37-
<PAGE>

country having jurisdiction over the Aircraft or in violation of any
airworthiness certificate, license or registration relating to the Aircraft
issued by any such government, except to the extent Company (or, if a Lease is
then in effect, any Permitted Lessee) is contesting in good faith the validity
or application of any such law, rule or regulation in any manner that does not
involve any material risk of sale, forfeiture or loss of the Aircraft or impair
the Lien of this Indenture; provided, that Company shall not be in default
under, or required to take any action set forth in, this sentence if it is not
possible for it to comply with the laws of a jurisdiction other than the United
States (or other than any jurisdiction in which the Aircraft is then
registered) because of a conflict with the applicable laws of the United States
(or such jurisdiction in which the Aircraft is then registered). Company will
not operate the Aircraft, or permit the Aircraft to be operated or located, (i)
in any area excluded from coverage by any insurance required by the terms of
Section 7.06 or (ii) in any war zone or recognized or, in Company's judgment,
threatened areas of hostilities unless covered by war risk insurance in
accordance with Section 7.06, unless in the case of either clause (i) or (ii),
(x) government indemnification complying with Section 7.06 (a) and (b) has been
provided or (y) the Aircraft is only temporarily located in such area as a
result of an isolated occurrence or isolated series of occurrences attributable
to a hijacking, medical emergency, equipment malfunction, weather conditions,
navigational error or other similar unforeseen circumstances and Company is
using its good faith efforts to remove the Aircraft from such area as promptly
as practicable.

         (c)      Maintenance. Company shall maintain, service, repair and
overhaul the Aircraft (or cause the same to be done) (i) so as to keep the
Aircraft in good operating condition and in such condition as may be necessary
to enable the airworthiness certification of the Aircraft to be maintained in
good standing at all times (other than during temporary periods of storage,
during maintenance, testing or modification permitted hereunder, or during
periods of grounding by applicable governmental authorities) under the
Transportation Code, during such periods in which the Aircraft is registered
under the laws of the United States, or, if the Aircraft is registered under
the laws of any other jurisdiction, the applicable laws of such jurisdiction
and (ii) using the same standards as Company (or a Permitted Lessee, if a Lease
is in effect) uses with respect to similar aircraft operated by Company (or
such Permitted Lessee) in similar circumstances (it being understood that the
obligations pursuant to this clause (ii) do not limit Company's obligations
under the preceding clause (i)). In any case, the Aircraft will be maintained
in accordance with the maintenance standards required by the FAA (while
operated under an FAA-approved maintenance program) or, while operated under
the maintenance program of another jurisdiction, standards substantially
equivalent to those required by the central aviation authority of Australia,
Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy,
Japan, the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland or the
United Kingdom. Company shall maintain or cause to be maintained all records,
logs and other documents required to be maintained in respect of the Aircraft
by appropriate authorities in the jurisdiction in which the Aircraft is
registered.

         (d)      Identification of Loan Trustee's Interest. Company agrees to
affix as promptly as practicable after the Closing Date and thereafter to
maintain in the cockpit of the Aircraft, in a clearly visible location, and (if
not prevented by applicable law or regulations or by any government) on each
Engine, a nameplate bearing the inscription "MORTGAGED TO U.S. BANK TRUST
NATIONAL ASSOCIATION, AS LOAN TRUSTEE" (such nameplate to be replaced, if
necessary, with a nameplate reflecting the name of any successor Loan Trustee).

                                     -38-
<PAGE>

         (e)      Registration. Company shall cause the Aircraft to remain duly
registered, under the laws of the United States, in the name of Company except
as otherwise required by the Transportation Code; provided that Loan Trustee
shall, at Company's expense, execute and deliver all such documents as Company
may reasonably request for the purpose of continuing such registration.
Notwithstanding the preceding sentence, Company, at its own expense, may cause
or allow the Aircraft to be duly registered under the laws of any foreign
jurisdiction in which a Permitted Lessee could be principally based, in the
name of Company or of any nominee of Company, or, if required by applicable
law, in the name of any other Person (and, following any such foreign
registration, may cause the Aircraft to be re-registered under the laws of the
United States); provided, that in the case of jurisdictions other than those
approved by Loan Trustee with the consent of a Majority in Interest of
Noteholders (i) if such jurisdiction is at the time of registration listed on
Exhibit B, Loan Trustee and Policy Provider shall have received at the time of
such registration an opinion of counsel to Company reasonably satisfactory to
Loan Trustee to the effect that (A) this Indenture and Loan Trustee's right to
repossession thereunder is valid and enforceable under the laws of such
country, (B) after giving effect to such change in registration, the Lien of
this Indenture shall continue as a valid first priority Lien and shall be duly
perfected in the new jurisdiction of registration and that all filing,
recording or other action necessary to perfect and protect the Lien of this
Indenture has been accomplished (or if such opinion cannot be given at such
time, (x) the opinion shall detail what filing, recording or other action is
necessary and (y) Loan Trustee and Policy Provider shall have received a
certificate from a Responsible Officer of Company that all possible
preparations to accomplish such filing, recording and other action shall have
been done, and such filing, recording and other action shall be accomplished
and a supplemental opinion to that effect shall be promptly delivered to Loan
Trustee subsequent to the effective date of such change in registration), (C)
the obligations of Company under this Indenture shall remain valid, binding and
(subject to customary bankruptcy and equitable remedies exceptions and to other
exceptions customary in foreign opinions generally) enforceable under the laws
of such jurisdiction (or the laws of the jurisdiction to which the laws of such
jurisdiction would refer as the applicable governing law), (D) all approvals or
consents of any government in such jurisdiction having jurisdiction required
for such change in registration shall have been duly obtained and shall be in
full force and effect and (E) (unless Company shall have agreed to provide
insurance covering the risk of requisition of use or title of the Aircraft by
the government of such jurisdiction so long as the Aircraft is registered under
the laws of such jurisdiction) the laws of such jurisdiction require fair
compensation by the government of such jurisdiction payable in currency freely
convertible into Dollars for the loss of use or title of the Aircraft in the
event of requisition by such government of such use or title, and (ii) if such
jurisdiction is at the time of registration not listed on Exhibit B, Loan
Trustee shall have received (in addition to the opinions set forth in clause
(i) above) at the time of such registration an opinion of counsel to Company
reasonably satisfactory to Loan Trustee to the effect that (A) the terms of
this Indenture are legal, valid, binding and enforceable in such jurisdiction
(subject to exceptions customary in such jurisdiction, provided, that, subject
to exceptions relating to bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the rights of creditors generally and exceptions
relating to general principles of equity, such counsel shall opine that any
applicable laws limiting the remedies provided in Section 4.02 do not in the
opinion of such counsel make the remedies provided in Section 4.02 inadequate
for the practical realization of the rights and benefits provided thereby), (B)
it is not necessary for Loan Trustee to register or qualify to do business in
such jurisdiction and (C) there is no tort

                                     -39-
<PAGE>

liability of the lender of an aircraft not in possession thereof under the laws
of such jurisdiction other than tort liability that might have been imposed on
such lender under the laws of the United States or any state thereof (it being
understood that such opinion shall be waived if insurance reasonably
satisfactory to Loan Trustee is provided, at Company's expense, to cover such
risk). Loan Trustee will cooperate with Company in effecting such foreign
registration. Notwithstanding the foregoing, prior to any such change in the
country of registry of the Aircraft, the following conditions shall be met (or
waived as provided in Section 6.01(b) of the Participation Agreement):

                  (i)      no Event of Default shall have occurred and be
         continuing at the effective date of the change in registration;
         provided, that it shall not be necessary to comply with this condition
         if the change in registration results in the registration of the
         Aircraft under the laws of the United States or if a Majority in
         Interest of Noteholders consents to such change in registration;

                  (ii)     Loan Trustee shall have received evidence of
         compliance with the insurance provisions contained herein after giving
         effect to such change in registration;

                  (iii)    other than in the case of a change in registration
         to Taiwan, the proposed change in registration is made to a country
         with which the United States then maintains normal diplomatic
         relations, and in the case of a change in registration to Taiwan, the
         United States maintains diplomatic relations with Taiwan at least as
         good as those on the Closing Date;

                  (iv)     the indemnities in favor of each Person named as an
         indemnitee under any other Operative Document afford each such Person
         substantially the same protection as provided prior to such change of
         registration (or Company shall have agreed upon additional indemnities
         that, together with such original indemnities, to the reasonable
         satisfaction of Loan Trustee, afford such protection); and

                  (v)      Company shall have paid or made provision reasonably
         satisfactory to Loan Trustee for the payment of all reasonable
         expenses (including reasonable attorneys' fees) of Loan Trustee and
         Noteholders in connection with such change in registration.

         Section 7.03 Inspection; Financial Information. (a) Inspection. At all
reasonable times, but upon at least 15 Business Days' prior written notice to
Company, Policy Provider or Loan Trustee or their respective authorized
representatives may, subject to the other conditions of this Section 7.03(a),
inspect the Aircraft and may inspect the books and records of Company relating
to the maintenance of the Aircraft required to be maintained by the FAA or the
government of another jurisdiction in which the Aircraft is then registered;
provided, that (i) Policy Provider or Loan Trustee or their respective
representatives, as the case may be, shall be fully insured at no cost to
Company in a manner satisfactory to Company with respect to any risks incurred
in connection with any such inspection or shall provide to Company a written
release satisfactory to Company with respect to such risks, (ii) any such
inspection shall be during Company's normal business hours and subject to the
safety, security and workplace rules applicable at the location where such
inspection is conducted and any applicable governmental rules or regulations,
(iii) any such inspection of the Aircraft shall be a visual, walk-around

                                     -40-
<PAGE>

inspection of the interior and exterior of the Aircraft and shall not include
opening any panels, bays or the like without Company's express consent, which
consent Company may in its sole discretion withhold, and (iv) no exercise of
such inspection right shall interfere with the use, operation or maintenance of
the Aircraft by, or the business of, Company and Company shall not be required
to undertake or incur any additional liabilities in connection therewith. All
information obtained in connection with any such inspection of the Aircraft and
of such books and records shall be Confidential Information and shall be
treated by Policy Provider and Loan Trustee and their respective
representatives in accordance with the provisions of Section 10.16. Any
inspection pursuant to this Section 7.03(a) shall be at the sole risk
(including, without limitation, any risk of personal injury or death) and
expense of Policy Provider or Loan Trustee (or their respective
representatives) making such inspection. Except during the continuance of an
Event of Default, all inspections by Policy Provider and Loan Trustee and their
respective representatives provided for under this Section 7.03(a) shall be
limited to one inspection of any kind contemplated by this Section 7.03(a)
during any consecutive twelve month period.

         (b)      Financial Information. So long as any of the Secured
Obligations remain unpaid, Company agrees to furnish to Loan Trustee and Policy
Provider: (i) within 60 days after the end of each of the first three quarterly
periods in each fiscal year of Company, either (x) a consolidated balance sheet
of Company and its consolidated subsidiaries prepared by it as of the close of
such period, together with the related consolidated statements of income for
such period or (y) a report of Company on Form 10-Q in respect of such period
in the form filed with the Securities and Exchange Commission and (ii) within
120 days after the close of each fiscal year of Company, either (x) a
consolidated balance sheet of Company and its consolidated subsidiaries as of
the close of such fiscal year, together with the related consolidated
statements of income for such fiscal year, certified by independent public
accountants, or (y) a report of Company on Form 10-K in respect of such year in
the form filed with the Securities and Exchange Commission. Company may fulfill
the requirements of this Section 7.03(b) by providing the material described
above in an electronic format by electronic mail or accessible over the
Internet.

         Section 7.04 Replacement and Pooling of Parts; Alterations,
Modifications and Additions; Substitution of Engines. (a) Replacement of Parts.
Company shall promptly replace or cause to be replaced all Parts incorporated
or installed in or attached to the Airframe or any Engine and that become worn
out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
rendered permanently unfit for use for any reason, except as otherwise provided
in Section 7.04(c) or if the Airframe or an Engine to which a Part relates has
suffered an Event of Loss. In addition, Company (or any Permitted Lessee) may
remove in the ordinary course of maintenance, service, repair, overhaul or
testing, any Parts, whether or not worn out, lost, stolen, destroyed, seized,
confiscated, damaged beyond repair or rendered permanently unfit for use;
provided that Company (or any Permitted Lessee), except as otherwise provided
in Section 7.04(c), will replace such Parts as promptly as practicable. All
replacement Parts shall be free and clear of all Liens (except for Permitted
Liens and except in the case of replacement property temporarily installed on
an emergency basis) and shall be in the condition and repair required to be
maintained by the terms hereof. Except as otherwise provided in Section
7.04(c), any Parts removed from the Airframe or any Engine shall remain subject
to the Lien of this Indenture no matter where located until it is replaced by a
part incorporated or installed in or attached to the Airframe or such Engine
that meets the requirements for replacement Parts specified above.

                                     -41-
<PAGE>

Immediately upon any replacement Part becoming incorporated or installed in or
attached to the Airframe or any Engine as above provided (except in the case of
replacement property temporarily installed on an emergency basis), without
further act, (i) the replaced Part shall thereupon be free and clear of all
rights of Loan Trustee and of the Lien of this Indenture and shall no longer be
deemed a Part hereunder, and (ii) such replacement Part shall become subject to
the Lien of this Indenture and be deemed a Part of the Airframe or such Engine
for all purposes to the same extent as the Parts originally incorporated or
installed in or attached to the Airframe or such Engine. Upon request of
Company from time to time, Loan Trustee shall execute and deliver to Company an
appropriate instrument confirming the release of any such replaced Part from
the Lien of this Indenture.

         (b)      Pooling of Parts. Any Part removed from the Airframe or any
Engine as provided in Section 7.04(a) may be subjected by Company or a Person
permitted to be in possession of the Aircraft to a pooling arrangement entered
into in the ordinary course of Company's or such Person's business; provided
that the part replacing such removed Part shall be incorporated or installed in
or attached to the Airframe or such Engine in accordance with Section 7.04(a)
as promptly as practicable after the removal of such removed Part. In addition,
any replacement Part when incorporated or installed in or attached to the
Airframe or any Engine may be owned by any third party subject to such a
pooling arrangement; provided that Company, at its expense, as promptly
thereafter as practicable either (i) causes title to such replacement Part to
vest in Company free and clear of all Liens (except Permitted Liens), or (ii)
replaces such replacement Part by incorporating or installing in or attaching
to the Airframe or such Engine a further replacement Part in the manner
contemplated by Section 7.04(a).

         (c)      Alterations, Modifications and Additions. Company will make
(or cause to be made) such alterations and modifications in and additions to
the Airframe and the Engines as are required from time to time to meet the
applicable requirements of the FAA or any applicable government of any other
jurisdiction in which the Aircraft is then registered; provided, however, that
Company (or, if a Lease is then in effect, any Permitted Lessee) may, in good
faith, contest the validity or application of any such requirement in any
manner that does not involve any material risk of sale, loss or forfeiture of
the Aircraft and does not adversely affect Loan Trustee's interest in the
Collateral. In addition, Company (or any Permitted Lessee), at its own expense,
may from time to time add further parts or accessories and make or cause to be
made such alterations and modifications in and additions to the Airframe or any
Engine as Company (or any Permitted Lessee) deems desirable in the proper
conduct of its business, including, without limitation, removal (without
replacement) of Parts, provided that no such alteration, modification or
addition shall materially diminish the value or utility of the Airframe or such
Engine below its value or utility immediately prior to such alteration,
modification or addition, assuming that the Airframe or such Engine was then in
the condition required to be maintained by the terms of this Indenture, except
that the value (but not the utility) of the Airframe or any Engine may be
reduced by the value of any such Parts that are removed that Company deems
obsolete or no longer suitable or appropriate for use on the Airframe or any
Engine. All Parts incorporated or installed in or attached or added to the
Airframe or any Engine as the result of such alteration, modification or
addition shall, without further act, be subject to the Lien of this Indenture.
Notwithstanding the foregoing, Company (or any Permitted Lessee) may, at any
time, remove any Part from the Airframe or any Engine if such Part: (i) is in
addition to, and not in replacement of or substitution for, any Part originally
incorporated or installed in or

                                     -42-
<PAGE>

attached to the Airframe or such Engine at the time of delivery thereof to
Company or any Part in replacement of, or substitution for, any such Part, (ii)
is not required to be incorporated or installed in or attached or added to the
Airframe or such Engine pursuant to the first sentence of this Section 7.04(c)
and (iii) can be removed from the Airframe or such Engine without materially
diminishing the value or utility required to be maintained by the terms of this
Indenture that the Airframe or such Engine would have had at such time had such
removal not occurred. Upon the removal by Company (or any Permitted Lessee) of
any Part as permitted by this Section 7.04(c), such removed Part shall, without
further act, be free and clear of all rights and interests of Loan Trustee and
the Lien of this Indenture and shall no longer be deemed a Part hereunder. Upon
request of Company from time to time, Loan Trustee shall execute and deliver to
Company an appropriate instrument confirming the release of any such removed
Part from the Lien of this Indenture.

         (d)      Substitution of Engines. Company shall have the right at its
option at any time, on at least 30 days' prior written notice to Loan Trustee,
to substitute a Replacement Engine for any Engine. In such event, and prior to
the date of such substitution, Company shall replace such Engine by complying
with the terms of Section 7.05(b) to the same extent as if an Event of Loss had
occurred with respect to such Engine.

         Section 7.05 Loss, Destruction or Requisition. (a) Event of Loss with
Respect to the Airframe. Upon the occurrence of an Event of Loss with respect
to the Airframe or the Airframe and the Engines then installed thereon, Company
shall as soon as practicable (and, in any event, within 30 days after an Event
of Loss has occurred) notify Loan Trustee of such Event of Loss, and, within 90
days after such Event of Loss, Company shall give Loan Trustee written notice
of its election to perform one of the following options (it being agreed that
if Company has not given such notice of election within such 90-day period,
Company shall be deemed to have elected to perform the option set forth in the
following clause (ii)). Company may elect either to:

                  (i)      substitute, on or before the Loss Payment Date (as
         defined below), as replacement for the Airframe or Airframe and
         Engines with respect to which an Event of Loss has occurred, a
         Replacement Airframe (together with a number of Replacement Engines
         equal to the number of Engines, if any, with respect to which the
         Event of Loss occurred), such Replacement Airframe and Replacement
         Engines to be owned by Company free and clear of all Liens (other than
         Permitted Liens); provided that if Company has not performed such
         obligation on or prior to the Loss Payment Date, then Company shall on
         the Loss Payment Date prepay the Equipment Notes in full in accordance
         with Section 2.10; or

                  (ii)     redeem, on or before the Loss Payment Date, the
         Equipment Notes in full in accordance with Section 2.10. Company shall
         give Loan Trustee 20 days prior written notice if it elects to redeem
         the Equipment Notes on any day prior to the Loss Payment Date.

         The "Loss Payment Date" with respect to an Event of Loss means the
Business Day next succeeding the 120th day following the date of occurrence of
such Event of Loss.

                                     -43-
<PAGE>

         If Company elects to substitute a Replacement Airframe (or a
Replacement Airframe and one or more Replacement Engines, as the case may be)
Company shall, at its sole expense, not later than the Loss Payment Date, (A)
cause an Indenture Supplement for such Replacement Airframe and Replacement
Engines, if any, to be delivered to Loan Trustee for execution and, upon such
execution, to be filed for recordation pursuant to the Transportation Code or
the applicable laws of such other jurisdiction in which the Aircraft is then
registered, (B) cause a financing statement or statements with respect to the
Replacement Airframe and Replacement Engines, if any, or other requisite
documents or instruments to be filed in such place or places as necessary in
order to perfect Loan Trustee's interest therein in the United States, or in
any other jurisdiction in which the Aircraft is then registered, (C) furnish
Loan Trustee with an opinion of Company's counsel (which may be internal
counsel of Company) addressed to Loan Trustee to the effect that upon such
replacement, such Replacement Airframe and Replacement Engines, if any, will be
subject to the Lien of this Indenture and addressing the matters set forth in
clauses (A) and (B), (D) furnish Loan Trustee with a certificate of an
independent aircraft engineer or appraiser, certifying to the reasonable
satisfaction of Loan Trustee that the Replacement Airframe and Replacement
Engines, if any, have a value and utility (without regard to hours or cycles)
at least equal to the Airframe and Engines, if any, so replaced, assuming the
Airframe and such Engines were in the condition and repair required by the
terms hereof immediately prior to the occurrence of such Event of Loss and that
such Replacement Airframe shall have been delivered from the Manufacturer no
earlier than one year prior to the date that the Airframe being replaced was
delivered from the Manufacturer, (E) furnish Loan Trustee with evidence of
compliance with the insurance provisions of Section 7.06 with respect to such
Replacement Airframe and Replacement Engines, if any, (F) furnish Loan Trustee
with a copy of the original bill of sale respecting such Replacement Airframe
and a copy of the original bill of sale or, if the bill of sale is unavailable,
other evidence of ownership reasonably satisfactory to Loan Trustee (which may
be a copy of an invoice or purchase order) respecting such Replacement Engines,
if any, and (G) furnish Loan Trustee with an opinion of Company's counsel
(which may be internal counsel of Company) reasonably satisfactory to Loan
Trustee to the effect that Loan Trustee will be entitled to the benefits of
Section 1110 with respect to the Replacement Airframe, provided that (i) such
opinion need not be delivered to the extent that the benefits of Section 1110
were not, by reason of a change in law or governmental or judicial
interpretation thereof, available to Loan Trustee with respect to the Aircraft
immediately prior to such substitution and (ii) such opinion may contain
qualifications and assumptions of the tenor contained in the Section 1110
opinion of Company's special counsel delivered pursuant to Section 3.01 of the
Participation Agreement on the Closing Date and such other qualifications and
assumptions as are at the time customary in opinions rendered in comparable
circumstances.

         In the case of each Replacement Airframe or Replacement Airframe and
one or more Replacement Engines subjected to the Lien of this Indenture under
this Section 7.05(a), promptly upon the recordation of the Indenture Supplement
covering any such Replacement Airframe and Replacement Engines, if any,
pursuant to the Transportation Code (or pursuant to the applicable law of such
other jurisdiction in which such Replacement Airframe and Replacement Engines,
if any, are registered), Company will cause to be delivered to Loan Trustee a
favorable opinion of FAA counsel selected by Company and reasonably
satisfactory to Loan Trustee if at the time of the Event of Loss the Aircraft
was registered under the laws of the United States (or, if at the time of the
Event of Loss the Aircraft was registered under the laws of another
jurisdiction, counsel qualified to opine on matters of registration in such
jurisdiction

                                     -44-
<PAGE>

selected by Company, which counsel shall be reasonably satisfactory to Loan
Trustee) addressed to Loan Trustee as to the due registration of such
Replacement Aircraft and the due recordation of such Indenture Supplement or
such other requisite documents or instruments and the validity and perfection
of the security interest in the Replacement Aircraft granted to Loan Trustee
under this Indenture.

         For all purposes hereof, upon the attachment of the Lien of this
Indenture thereto, the Replacement Aircraft and Replacement Engines, if any,
shall become part of the Collateral, the Replacement Airframe shall be deemed
an "Airframe" as defined herein, and each such Replacement Engine shall be
deemed an "Engine" as defined herein. Upon compliance with clauses (A) through
(F) of the third paragraph of this Section 7.05(a), Loan Trustee shall execute
and deliver to Company an appropriate instrument releasing such replaced
Airframe and Engines (if any) installed thereon at the time such Event of Loss
occurred, all proceeds (including, without limitation, insurance proceeds), the
Warranty Rights in respect of such replaced Airframe and Engines (if any) and
all rights relating to the foregoing, from the Lien of this Indenture and
assigning to Company all claims against third Persons for damage to or loss of
the Airframe and Engines arising from the Event of Loss.

         If, after an Event of Loss, Company performs the option set forth in
clause (ii) of the first paragraph of this Section 7.05(a), Loan Trustee shall
execute and deliver to Company an appropriate instrument releasing the
Aircraft, all proceeds (including, without limitation, insurance proceeds), the
Warranty Rights in respect of the Aircraft and all rights relating to the
foregoing from the Lien of this Indenture and assigning to Company all claims
against third Persons for damage to or loss of the Aircraft arising from the
Event of Loss.

         (b)      Event of Loss with Respect to an Engine. Upon the occurrence
of an Event of Loss with respect to an Engine under circumstances in which
there has not occurred an Event of Loss with respect to the Airframe, Company
shall give Loan Trustee prompt written notice thereof and shall, within 120
days after the occurrence of such Event of Loss, cause to be subjected to the
Lien of this Indenture, as replacement for the Engine with respect to which
such Event of Loss occurred, a Replacement Engine free and clear of all Liens
(other than Permitted Liens).

         Prior to or at the time of any replacement under this Section 7.05(b),
Company will (i) cause an Indenture Supplement covering such Replacement Engine
to be delivered to Loan Trustee for execution and, upon such execution, to be
filed for recordation pursuant to the Transportation Code or the applicable
laws of any other jurisdiction in which the Aircraft is then registered, (ii)
furnish Loan Trustee with a copy of the original bill of sale or, if the bill
of sale is unavailable, other evidence of ownership reasonably satisfactory to
Loan Trustee (which may be a copy of an invoice or purchase order) respecting
such Replacement Engine, (iii) cause a financing statement or statements with
respect to such Replacement Engine or other requisite documents or instruments
to be filed in such place or places as necessary in order to perfect Loan
Trustee's interest therein in the United States, or in such other jurisdiction
in which the Engine is then registered, (iv) furnish Loan Trustee with an
opinion of Company's counsel (which may be internal counsel to Company)
reasonably satisfactory to Loan Trustee addressed to Loan Trustee to the effect
that, upon such replacement, the Replacement Engine will be subject to the Lien
of this Indenture, (v) furnish Loan Trustee with a certificate of an aircraft
engineer or appraiser

                                     -45-
<PAGE>

(who may be an employee of Company) certifying to the reasonable satisfaction
of Loan Trustee that such Replacement Engine has a value and utility (without
regard to hours or cycles) at least equal to the Engine so replaced assuming
such Engine was in the condition and repair required by the terms hereof
immediately prior to the occurrence of such Event of Loss and (v) furnish Loan
Trustee with evidence of compliance with the insurance provisions of Section
7.06 with respect to such Replacement Engine. In the case of each Replacement
Engine subjected to the Lien of this Indenture under this Section 7.05(b),
promptly upon the recordation of the Indenture Supplement covering such
Replacement Engine pursuant to the Transportation Code (or pursuant to the
applicable law of such other jurisdiction in which the Aircraft is registered),
Company will cause to be delivered to Loan Trustee an opinion of FAA counsel
selected by Company reasonably satisfactory to Loan Trustee if at the time of
the Event of Loss the Aircraft was registered under the laws of the United
States (or, if at the time of the Event of Loss the Aircraft was registered
under the laws of another jurisdiction, counsel qualified to opine on matters
of registration in such jurisdiction selected by Company, which counsel shall
be reasonably satisfactory to Loan Trustee) addressed to Loan Trustee as to the
due recordation of such Indenture Supplement or such other requisite documents
or instruments and the validity and perfection of the security interest in the
Replacement Engine granted to Loan Trustee under this Indenture. For all
purposes hereof, upon the attachment of the Lien of this Indenture thereto, the
Replacement Engine shall become part of the Collateral and shall be deemed an
"Engine" as defined herein. Upon compliance with clauses (i) through (v) of the
first sentence of this paragraph, Loan Trustee shall execute and deliver to
Company an appropriate instrument releasing such replaced Engine, any proceeds
(including, without limitation, insurance proceeds), the Warranty Rights in
respect of such replaced Engine and all rights relating to any of the foregoing
from the Lien of this Indenture and assigning to Company all claims against
third Persons for damage to or loss of such Engine arising from the Event of
Loss.

         (c)      Application of Payments for Event of Loss from Requisition of
Title or Use. Any payments other than insurance proceeds (the application of
which is provided for in Section 7.06) received at any time by Company or by
Loan Trustee from any government or other Person with respect to an Event of
Loss to the Airframe or any Engine, will be applied as follows:

                  (i)      if such payments are received with respect to the
         Airframe or the Airframe and any Engines installed on the Airframe
         that has been or is being replaced by Company pursuant to Section
         7.05(a), such payments shall be paid over to, or retained by, Loan
         Trustee and upon completion of such replacement shall be paid over to,
         or retained by, Company;

                  (ii)     if such payments are received with respect to the
         Airframe or the Airframe and any Engines installed on the Airframe
         that has not been and will not be replaced pursuant to Section
         7.05(a), so much of such payments remaining after reimbursement of
         Loan Trustee for costs and expenses that shall not exceed the amounts
         required to be paid to Noteholders pursuant to Section 2.10 shall be
         applied in reduction of Company's obligation to pay such amounts, if
         not already paid by Company, or, if already paid by Company, shall be
         applied to reimburse Company for its payment of such amount and the
         balance, if any, of such payment remaining thereafter will be paid
         over to, or retained by, Company; and

                                     -46-
<PAGE>

                  (iii)    if such payments are received with respect to an
         Engine with regard to which an Event of Loss has occurred, so much of
         such payments remaining after reimbursement of Loan Trustee for costs
         and expenses shall be paid over to, or retained by, Company; provided
         that Company has fully performed its obligations under Section 7.05(b)
         with respect to the Event of Loss for which such payments are made.

         (d)      Requisition for Use by the Government of the Airframe and the
Engines Installed Thereon. In the event of the requisition for use by any
government (it being acknowledged that the use of the Airframe or any Engine
pursuant to the CRAF Program does not constitute such a requisition) of the
Airframe and the Engines or engines installed on the Airframe that does not
constitute an Event of Loss, all of Company's rights and obligations under this
Indenture with respect to the Airframe and such Engines shall continue to the
same extent as if such requisition had not occurred; provided that,
notwithstanding the foregoing, Company's obligations other than payment
obligations shall only continue to the extent feasible. All payments received
by Company or Loan Trustee from such government for such use of the Airframe
and Engines or engines shall be paid over to, or retained by, Company.

         (e)      Requisition for Use by the Government of an Engine not
Installed on the Airframe. If any government requisitions the use, for a period
in excess of sixty (60) days, of any Engine not then installed on the Airframe,
Company will replace such Engine by complying with the terms of Section 7.05(b)
to the same extent as if an Event of Loss had occurred with respect to such
Engine. Upon such replacement, any payments received by Company or Loan Trustee
from such government with respect to such requisition shall be paid over to, or
retained by, Company.

         (f)      Application of Payments During Existence of Event of Default.
Any amount referred to in Section 7.05 that is payable to or retainable by
Company shall not be paid to or retained by Company if at the time of such
payment or retention an Event of Default or Payment Default has occurred and is
continuing, but shall be held by or paid over to Loan Trustee as security for
the obligations of Company under this Indenture, the Participation Agreement,
the Related Indentures and the Related Participation Agreements. When any such
Event of Default or Payment Default ceases, such amount shall be paid to
Company.

         Section 7.06 Insurance. (a) Aircraft Liability Insurance. (i) Except
as provided in clause (ii) of this subsection (a), and subject to the rights of
Company to establish and maintain self-insurance in the manner and to the
extent specified in Section 7.06(c), Company will carry, or cause to be
carried, at no expense to Loan Trustee, aircraft liability insurance
(including, but not limited to, bodily injury, personal injury and property
damage liability, exclusive of manufacturer's product liability insurance) and
contractual liability insurance with respect to the Aircraft (A) in amounts
that are not less than the aircraft liability insurance applicable to similar
aircraft and engines in Company's fleet on which Company carries insurance;
provided that such liability insurance shall not be less than the amount
certified in the insurance report delivered to Loan Trustee on the Closing
Date, (B) of the type covering the same risks as from time to time applicable
to aircraft operated by Company (or, if a Lease is then in effect, by the
Permitted Lessee) of the same type as the Aircraft, and (C) that is maintained
in effect with insurers of recognized responsibility. Any policies of insurance
carried in accordance with this Section 7.06(a) and any policies taken out in
substitution or replacement for any of such

                                     -47-
<PAGE>

policies shall: (A) name Loan Trustee, Subordination Agent, each Pass Through
Trustee, Policy Provider and each Liquidity Provider as their Interests (as
defined below in this Section 7.06) may appear, as additional insured (the
"Additional Insureds"), (B) subject to the condition of clause (C) below,
provide that, in respect of the interest of the Additional Insureds in such
policies, the insurance shall not be invalidated by any action or inaction of
Company and shall insure the Additional Insureds' Interests as they appear,
regardless of any breach or violation of any warranty, declaration or condition
contained in such policies by Company, (C) provide that, if such insurance is
canceled for any reason whatever, or if any change is made in the policy that
materially reduces the amount of insurance or the coverage certified in the
insurance report delivered on the Closing Date to Loan Trustee, Policy Provider
and Liquidity Providers, or if such insurance is allowed to lapse for
nonpayment of premium, such cancellation, change or lapse shall not be
effective as to any Additional Insured for 30 days (seven days, or such other
period as is then generally available in the industry, in the case of any war
risk or allied perils coverage) after receipt by such Additional Insured of
written notice from such insurers of such cancellation, change or lapse, (D)
provide that the Additional Insureds shall have no obligation or liability for
premiums, commissions, assessments or calls in connection with such insurance,
(E) provide that the insurers shall waive any rights of (1) set-off,
counterclaim or any other deduction, whether by attachment or otherwise, in
respect of any liability of the Additional Insureds to the extent of any moneys
due to the Additional Insureds and (2) subrogation against the Additional
Insureds to the extent that Company has waived its rights by its agreements to
indemnify the Additional Insureds pursuant to the Operative Documents, (F) be
primary without right of contribution from any other insurance carried by any
Additional Insured with respect to its Interests as such in the Aircraft and
(G) expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured. "Interests" as used in this Section 7.06(a) and in
Section 7.06(b) with respect to any Person means the interests of such Person
in the transactions contemplated by the Operative Documents. In the case of a
lease or contract with any government in respect of the Aircraft or any Engine,
or in the case of any requisition for use of the Aircraft or any Engine by any
government, a valid agreement by such government to indemnify Company, or an
insurance policy issued by such government, against any of the risks that
Company is required to insure against hereunder shall be considered adequate
insurance for purposes of this Section 7.06(a) to the extent of the risks (and
in the amounts) that are the subject of such indemnification or insurance.

         (ii)     During any period that the Airframe or an Engine, as the case
may be, is on the ground and not being flown, Company may carry or cause to be
carried as to such non-flown Airframe or Engine, in lieu of the insurance
required by clause (i) above, and subject to self-insurance to the extent
permitted by Subsection 7.06(c), insurance otherwise conforming with the
provisions of said clause (i) except that: (A) the amounts of coverage shall
not be required to exceed the amounts of airline liability insurance from time
to time applicable to airframes or engines owned or leased by Company (or, if a
Lease is then in effect, by the Permitted Lessee) of the same type as such
non-flown Airframe or Engine and that are on the ground and not being flown and
(B) the scope of the risks covered and the type of insurance shall be the same
as from time to time are applicable to airframes or engines operated by Company
(or, if a Lease is then in effect, by the Permitted Lessee) of the same type as
such non-flown Airframe or Engine and that are on the ground and not being
flown.

                                     -48-

         (b)      Insurance Against Loss or Damage to Aircraft. (i) Except as
provided in clause (ii) of this subsection (b), and subject to the rights of
Company to establish and maintain self-insurance in the manner and to the
extent specified in Section 7.06(c), Company shall maintain, or cause to be
maintained, in effect with insurers of recognized responsibility, at no expense
to Loan Trustee, all-risk aircraft hull insurance covering the Aircraft and
all-risk coverage with respect to any Engines or Parts while removed from the
Aircraft (including, without limitation, war risk insurance if and to the
extent the same is maintained by Company (or, if a Lease is then in effect, by
the Permitted Lessee) with respect to other similar aircraft operated by
Company or such Permitted Lessee, as the case may be, on the same routes) that
is of the type as from time to time applicable to the aircraft operated by
Company (or, if a Lease is then in effect, by the Permitted Lessee) of the same
type as the Aircraft; provided that (A) such insurance (including the permitted
self-insurance) shall at all times while the Aircraft is subject to this
Indenture be for an amount not less than 110% of the aggregate principal amount
of the Equipment Notes outstanding from time to time, (B) such insurance need
not cover an Engine while attached to an airframe not owned, leased or operated
by Company, and (C) such insurance covering Engines and Parts removed from an
Airframe or an airframe or (in the case of Parts) an Engine need be obtained
only to the extent available at reasonable cost (as reasonably determined by
Company). Any policies carried in accordance with this Section 7.06(b) and any
policies taken out in substitution or replacement for any such policies shall:
(A) provide that any insurance proceeds up to an amount equal to the
outstanding principal amount of the Equipment Notes, together with accrued but
unpaid interest thereon, plus an amount equal to the interest that would accrue
on the outstanding principal amount of the Equipment Notes at the Debt Rate in
effect on the date of payment of such insurance proceeds to Loan Trustee (as
provided for in this sentence) during the period commencing on the day
following the date of such payment to Loan Trustee and ending on the Loss
Payment Date (the sum of such three amounts being the "Loan Amount"), payable
for any loss or damage constituting an Event of Loss with respect to the
Aircraft and any insurance proceeds in excess of the amount set forth on
Exhibit C up to the amount of the Loan Amount for any loss or damage to the
Aircraft (or Engines) not constituting an Event of Loss with respect to the
Aircraft (or Engines), shall be paid to Loan Trustee as long as the Indenture
has not been discharged, and that all other amounts shall be payable to
Company, unless the insurer has received notice that an Event of Default
exists, in which case all insurance proceeds for any loss or damage to the
Aircraft (or Engines) shall be payable to Loan Trustee, (B) subject to the
conditions of clause (C) below, provide that, in respect of the interests of
the Additional Insureds in such policies, the insurance shall not be
invalidated by any action or inaction of Company and shall insure the
Additional Insureds' Interests as they appear, regardless of any breach or
violation by Company of any warranty, declaration or condition contained in
such policies, (C) provide that if such insurance is canceled for any reason,
or if any change is made in the insurance that materially reduces the coverage
(not including the amount) certified in the insurance report delivered on the
Closing Date to Loan Trustee, Policy Provider and Liquidity Providers or if
such insurance is allowed to lapse for nonpayment of premium, such
cancellation, change or lapse shall not be effective as to the Additional
Insureds for 30 days (seven days, or such other period as is customarily
available in the industry, in the case of war risk or allied perils coverage)
after receipt by the Additional Insureds of written notice from such insurers
of such cancellation, change or lapse, (D) provide that the Additional Insureds
shall have no obligation or liability for premiums, commissions, assessments or
calls in connection with such insurance, (E) provide that the insurers shall
waive rights of (1) setoff, counterclaim or any

                                     -49-
<PAGE>

other deduction, whether by attachment or otherwise, in respect of any
liability of the Additional Insureds to the extent of any moneys due to the
Additional Insureds and (2) subrogation against the Additional Insureds to the
extent Company has waived its rights by its agreement to indemnify the
Additional Insureds pursuant to the Operative Documents and (F) be primary
without right of contribution from any other insurance carried by any
Additional Insured with respect to its Interests as such in the Aircraft. In
the case of a lease or contract with any government in respect of the Aircraft
or any Engine, or in the case of any requisition for use of the Aircraft or any
Engine by any government, a valid agreement by such government to indemnify
Company, or an insurance policy issued by such government, against any risks
which Company is required hereunder to insure against shall be considered
adequate insurance for purposes of this Section 7.06(b) to the extent of the
risks (and in the amounts) that are the subject of such indemnification or
insurance.

         (ii)     During any period that the Airframe or an Engine is on the
ground and not being flown, Company may carry or cause to be carried as to such
non-flown Airframe or Engine, in lieu of the insurance required by clause (i)
above, and subject to self-insurance to the extent permitted by Subsection
7.06(c), insurance otherwise conforming with the provisions of said clause (i)
except that the scope of the risks covered and the type of insurance shall be
the same as from time to time applicable to airframes and engines operated by
Company (or, if a Lease is then in effect, by the Permitted Lessee) of the same
type as such non-flown Airframe or Engine and that are on the ground and not
being flown; provided that, subject to self-insurance to the extent permitted
by Subsection 7.06(c), Company shall maintain or cause to be maintained
insurance against risk of loss or damage to such non-flown Airframe or Engine
in an amount at least equal to 110% of the aggregate outstanding principal
amount of the Equipment Notes during such period that such Airframe or Engine
is on the ground and not being flown.

         (c)      Self-Insurance. Company may from time-to-time self-insure, by
way of deductible, self-insured retention, premium adjustment or franchise or
otherwise (including, with respect to insurance maintained pursuant to
Subsections 7.06(a) or 7.06(b), insuring for a maximum amount that is less than
the amounts set forth in Sections 7.06(a) and 7.06(b)), the risks required to
be insured against pursuant to Sections 7.06(a) and 7.06(b), but in no case
shall the self-insurance with respect to all of the aircraft and engines in
Company's fleet (including, without limitation, the Aircraft) exceed for any
12-month policy year 1% of the average aggregate insurable value (for the
preceding policy year) of all aircraft (including, without limitation, the
Aircraft) on which Company carries insurance, unless an insurance broker of
national standing certifies that the standard among other major United States
airlines is a higher level of self-insurance, in which case Company may
self-insure the Aircraft to such higher level. In addition to the foregoing
right to self-insure, Company may self-insure to the extent of (1) any
deductible per occurrence that, in the case of the Aircraft, is not in excess
of the amount customarily allowed as a deductible in the industry or is
required to facilitate claims handling or (2) any applicable mandatory minimum
per aircraft (or if applicable per annum or other period) hull or liability
insurance deductibles imposed by the aircraft hull or liability insurers.

         (d)      Application of Insurance Payments. All losses will be
adjusted by Company with the insurers. As between Loan Trustee and Company it
is agreed that all insurance payments received under policies required to be
maintained by Company hereunder, exclusive of any payments received in excess
of the Loan Amount for the Aircraft from such

                                     -50-
<PAGE>

policies, as the result of the occurrence of an Event of Loss with respect to
the Airframe or an Engine will be applied as follows:

                  (i)      if such payments are received with respect to the
         Airframe or the Airframe and any Engines installed on the Airframe
         that has been or is being replaced by Company pursuant to Section
         7.05(a), such payments shall be paid over to, or retained by, Loan
         Trustee and upon completion of such replacement shall be paid over to,
         or retained by, Company;

                  (ii)     if such payments are received with respect to the
         Airframe or the Airframe and any Engines installed on the Airframe
         that has not been and will not be replaced as contemplated by Section
         7.05(a), so much of such payments remaining after reimbursement of
         Loan Trustee for its costs and expenses as do not exceed the amounts
         required to be paid by Company pursuant to Section 2.10 shall be
         applied in reduction of Company's obligation to pay such amounts, if
         not already paid by Company, or, if already paid by Company, shall be
         applied to reimburse Company for its payment of such amounts and the
         balance, if any, of such payment remaining thereafter will be paid
         over to, or retained by, Company; and

                  (iii)    if such payments are received with respect to an
         Engine, so much of such payments remaining after reimbursement of Loan
         Trustee for its costs and expenses shall be paid over to, or retained
         by, Company; provided that Company has fully performed its obligations
         under Section 7.05(b) with respect to the Event of Loss for which such
         payments are made.

         In all events, the insurance payment of any property damage loss
received under policies maintained by Company in excess of the Loan Amount for
the Aircraft shall be paid to Company.

         The insurance payments for any loss or damage to the Airframe or an
Engine not constituting an Event of Loss with respect to the Airframe or such
Engine will be applied in payment (or to reimburse Company) for repairs or for
replacement property in accordance with the terms of Sections 7.02 and 7.04,
and any balance remaining after compliance with such Sections with respect to
such loss or damage shall be paid to Company. Any amount referred to in the
preceding sentence or in clause (i), (ii) or (iii) of the first paragraph of
this Section 7.06(d) that is payable to Company shall not be paid to Company
(or, if it has been previously paid directly to Company, shall not be retained
by Company) if at the time of such payment an Event of Default or Payment
Default has occurred and is continuing, but shall be paid to and held by Loan
Trustee as security for the obligations of Company under this Indenture, and
when any such Event of Default or Payment Default ceases, such amount shall, to
the extent not theretofore applied as provided herein, be paid to Company.

(e)      Reports, Etc. On or before the Closing Date and annually following
renewal of Company's insurance coverage, Company will furnish to Loan Trustee,
Policy Provider and Liquidity Providers a report signed by a firm of
independent aircraft insurance brokers appointed by Company (which brokers may
be in the regular employ of Company), stating the opinion of such firm that the
insurance then carried and maintained on the Aircraft

                                     -51-

complies with the terms hereof and all premiums then due in connection with the
insurance have been paid. All information contained in such report shall be
Confidential Information and shall be treated by Loan Trustee, Policy Provider
and Liquidity Providers and each of their affiliates and officers, directors,
agents and employees in accordance with the provisions of Section 10.16.
Company will cause such firm to notify Loan Trustee, Policy Provider and
Liquidity Providers of any act or omission on the part of Company of which such
firm has knowledge that might invalidate or render unenforceable, in whole or
in part, any insurance on the Aircraft. Company will also cause such firm to
notify Loan Trustee, Policy Provider and Liquidity Provider as promptly as
practicable after such firm acquires knowledge that an interruption of any
insurance carried and maintained on the Aircraft pursuant to this Section 7.06
will occur. Such information may only be provided to other Persons in
accordance with Section 10.16.

         (f)      Salvage Rights; Other. All salvage rights to the Airframe
and each Engine shall remain with Company's insurers at all times, and any
insurance policies of Loan Trustee insuring the Airframe or any Engine shall
provide for a release to Company of any and all salvage rights in and to the
Airframe or any Engine. Neither Loan Trustee nor any Noteholder may, directly or
indirectly, obtain insurance for its own account with respect to the Airframe
or any Engine if such insurance would limit or otherwise adversely affect the
coverage or amounts payable under, or increase the premiums for, any insurance
required to be maintained pursuant to this Section 7.06 or any other insurance
maintained with respect to the Aircraft or any other aircraft in Company's
fleet.

         (g)      Right to Pay Premium. Notwithstanding the foregoing, Company
agrees that in the event of cancellation of any insurance due to the
nonpayment of premiums, Loan Trustee shall have the option, in its sole
discretion, to pay any such premium that is due in respect of the coverage
pursuant to this Indenture and to maintain such coverage until the scheduled
expiry date of such insurance and, in such event, Company shall, upon demand,
reimburse Loan Trustee for amounts so paid by it.

                       SUCCESSOR AND ADDITIONAL TRUSTEES

         Section 8.01 Resignation or Removal; Appointment of Successor. (a) The
resignation or removal of Loan Trustee and the appointment of a successor Loan
Trustee shall become effective only upon the successor Loan Trustee's
acceptance of appointment as provided in this Section 8.01. Loan Trustee or any
successor thereto must resign if at any time it ceases to be eligible in
accordance with the provisions of Section 8.01(c) and may resign at any time
without cause by giving at least 60 days' prior written notice to Company and
each Noteholder. In addition, either Company (so long as no Event of Default or
Payment Default shall have occurred and be continuing) or a Majority in
Interest of Noteholders (but only with the consent of Company so long as no
Event of Default or Payment Default shall have occurred and be continuing), may
at any time remove Loan Trustee without cause by an instrument in writing
delivered to Loan Trustee and each Noteholder, and, in case of a removal by a
Majority in Interest of Noteholders, to Company. In the case of the resignation
or removal of Loan Trustee, Company shall promptly appoint a successor Loan
Trustee. If a successor Loan Trustee has not been appointed within 60 days
after such notice of resignation or removal, Loan Trustee,

                                     -52-
<PAGE>

Company or any Noteholder may apply to any court of competent jurisdiction to
appoint a successor Loan Trustee to act until such time, if any, as a successor
is appointed as above provided. The successor Loan Trustee so appointed by such
court shall immediately and without further act be superseded by any successor
Loan Trustee appointed as above provided.

         (b)      Any successor Loan Trustee, however appointed, shall execute
and deliver to the predecessor Loan Trustee and Company an instrument accepting
such appointment and assuming the obligations of Loan Trustee arising from and
after the time of such appointment, and thereupon such successor Loan Trustee,
without further act, shall become vested with all the estates, properties,
rights, powers and duties of the predecessor Loan Trustee in the trust
hereunder applicable to it with like effect as if originally named Loan Trustee
herein; but nevertheless upon the written request of such successor Loan
Trustee, such predecessor Loan Trustee shall execute and deliver an instrument
transferring to such successor Loan Trustee all the estates, properties, rights
and powers of such predecessor Loan Trustee, and such predecessor Loan Trustee
shall duly assign, transfer, deliver and pay over to such successor Loan
Trustee all monies or other property and all other books and records, or true,
correct and complete copies thereof, then held by such predecessor Loan
Trustee.

         (c)      This Indenture shall at all times have a Loan Trustee,
however appointed, that is a Citizen of the United States (without the use of a
voting trust) and a bank or trust company having a combined capital and surplus
of at least $100,000,000 (or a combined capital and surplus in excess of
$5,000,000 and the obligations of which, whether now in existence or hereafter
incurred, are fully and unconditionally guaranteed by a corporation organized
and doing business under the laws of the United States or any state or
territory thereof or the District of Columbia and having a combined capital and
surplus of at least $100,000,000) or a corporation with a net worth of at least
$100,000,000, if there be such an institution willing, able and legally
qualified to perform the duties of Loan Trustee upon reasonable or customary
terms. If such bank, trust company or corporation publishes reports of
conditions at least annually, pursuant to law or to the requirements of
federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 8.01(c) the combined capital
and surplus of such bank, trust company or corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
conditions so published. In case at any time Loan Trustee ceases to be eligible
in accordance with the provisions of this Section 8.01(c), Loan Trustee shall
resign immediately in the manner and with the effect specified in Section
8.01(a).

         (d)      Any corporation into which Loan Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which Loan Trustee is a party,
or any corporation to which substantially all the corporate trust business of
Loan Trustee may be transferred, shall, subject to the terms of Section
8.01(c), be a successor Loan Trustee under this Indenture without further act.

         Section 8.02 Appointment of Additional and Separate Trustees. (a)
Whenever (i) Loan Trustee deems it necessary or desirable in order to conform
to any law of any jurisdiction in which all or any part of the Collateral is
situated or to make any claim or bring any suit with respect to or in
connection with the Collateral, any Operative Document or any of the
transactions contemplated by the Operative Documents, (ii) Loan Trustee shall
be advised by

                                     -53-
<PAGE>

counsel satisfactory to it that it is necessary or prudent in the interests of
Noteholders (and Loan Trustee shall so advise Company) or (iii) Loan Trustee
has been requested to do so by a Majority in Interest of Noteholders, then in
any such case, Loan Trustee and, upon the written request of Loan Trustee,
Company, shall execute and deliver an indenture supplemental hereto and such
other instruments as from time to time are necessary or advisable either (1) to
constitute one or more banks or trust companies or corporations meeting the
requirements of Section 8.01(c) and approved by Loan Trustee, either to act
jointly with Loan Trustee as additional trustee or trustees of all or any part
of the Collateral or to act as separate trustee or trustees of all or any part
of the Collateral, in each case with such rights, powers, duties and
obligations consistent with this Indenture as is provided in such supplemental
indenture or other instruments as Loan Trustee or a Majority in Interest of
Noteholders deems necessary or advisable, or (2) to clarify, add to or subtract
from the rights, powers, duties and obligations theretofore granted any such
additional or separate trustee, subject in each case to the remaining
provisions of this Section 8.02. If no Event of Default has occurred and is
continuing, no additional or supplemental trustee shall be appointed without
Company's consent. If an Event of Default shall have occurred and be
continuing, Loan Trustee may act under the foregoing provisions of this Section
8.02(a) without the concurrence of Company, and Company hereby irrevocably
appoints (which appointment is coupled with an interest) Loan Trustee as its
agent and attorney-in-fact to act for it under the foregoing provisions of this
Section 8.02(a). Loan Trustee may, in such capacity, execute, deliver and
perform any such supplemental indenture, or any such instrument, as may be
required for the appointment of any such additional or separate trustee or for
the clarification of, addition to or subtraction from the rights, powers,
duties or obligations theretofore granted to any such additional or separate
trustee, subject in each case to the remaining provisions of this Section 8.02.
In case any additional or separate trustee appointed under this Section 8.02(a)
becomes incapable of acting, resigns or is removed, all the assets, property,
rights, powers, trusts, duties and obligations of such additional or separate
trustee shall revert to Loan Trustee until a successor additional or separate
trustee is appointed as provided in this Section 8.02(a).

         (b)      No additional or separate trustee shall be entitled to
exercise any of the rights, powers, duties and obligations conferred upon Loan
Trustee in respect of the custody, investment and payment of monies and all
monies received by any such additional or separate trustee from or constituting
part of the Collateral or otherwise payable under any Operative Documents to
Loan Trustee shall be promptly paid over by it to Loan Trustee. All other
rights, powers, duties and obligations conferred or imposed upon any additional
or separate trustee shall be exercised or performed by Loan Trustee and such
additional or separate trustee jointly except to the extent that applicable law
of any jurisdiction in which any particular act is to be performed renders Loan
Trustee incompetent or unqualified to perform such act, in which event such
rights, powers, duties and obligations (including the holding of title to all
or part of the Collateral in any such jurisdiction) shall be exercised and
performed by such additional or separate trustee. No additional or separate
trustee shall take any discretionary action except on the instructions of Loan
Trustee or a Majority in Interest of Noteholders. No trustee hereunder shall be
personally liable by reason of any act or omission of any other trustee
hereunder, except that Loan Trustee shall be liable for the consequences of its
lack of reasonable care in selecting, and Loan Trustee's own actions in acting
with, any additional or separate trustee. Each additional or separate trustee
appointed pursuant to this Section 8.02 shall be subject to, and shall have the
benefit of Articles IV, V, VI, VIII, IX and X hereof insofar as they apply to
Loan Trustee. The powers of any

                                     -54-
<PAGE>

additional or separate trustee appointed pursuant to this Section 8.02 shall
not in any case exceed those of Loan Trustee.

         (c)      If at any time Loan Trustee deems it no longer necessary or
desirable or in the event that Loan Trustee has been requested to do so in
writing by a Majority in Interest of Noteholders, Loan Trustee and, upon the
written request of Loan Trustee, Company, shall execute and deliver an
indenture supplemental hereto and all other instruments and agreements
necessary or proper to remove any additional or separate trustee. Loan Trustee
may act on behalf of Company under this Section 8.02(c) when and to the extent
it could so act under Section 8.02(a) hereof. In any case, Company may remove
an additional or separate trustee in the manner set forth in Section 8.01.

                                  ARTICLE IX

another Person to Company and the assumption by any such successor of the
covenants of Company contained in any Operative Documents pursuant to Section

removal of the trustee hereunder or to provide for or facilitate the

action shall not adversely affect the interests of Noteholders, Policy Provider
or either Liquidity Provider; (vii) to correct or amplify the description of
any property at any time subject to the Lien of this Indenture, or better to
assure, convey and confirm unto Loan Trustee any property subject or required
to be subject to the Lien of this Indenture or to subject to the Lien of this
Indenture the Airframe or Engines or any Replacement Airframe or Replacement
Engine; (viii) to add to the covenants of Company for the benefit of
Noteholders, or to surrender any rights or power herein conferred upon Company;
(ix) to add to the rights of Noteholders; (x) to include on the Equipment Notes

supplemental agreements or to modify in any manner the rights and obligations
of Company, Loan Trustee and of Noteholders under this Indenture; provided,

         the benefit of the Lien on the Collateral created by this Indenture;

                  (4)      reduce the percentage of the outstanding principal
         amount of the Equipment Notes the consent of whose holders is required
         for any such supplemental agreement, or the consent of whose holders

any supplemental agreement pursuant to the provisions of this Section 9.02,
Loan Trustee shall transmit by first-class mail a notice, setting forth in
general terms the substance of such supplemental agreement, to all Noteholders,
as the names and addresses of such Noteholders appear on the Equipment Note

therein, shall not, however, in any way impair or affect the validity of any
such supplemental agreement.
