Event of Default shall have occurred and be continuing, Company shall have the
right, to the exclusion of Loan Trustee, (i) 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;

          TO
HAVE AND TO HOLD all and singular the aforesaid property unto Loan Trustee, and
its successors and permitted assigns, in trust for the equal and proportionate
benefit and security of Noteholders, Indenture Indemnitees and Related
Indenture Indemnitees, except as otherwise provided in this Indenture,
including Section 2.13 and Article III, without any priority of any one
Equipment Note over any other, or any Related Equipment Note over any other, or
any Related Non-Subordination Agent 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 Noteholder, any other Indenture
Indemnitee or any Related 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, other Indenture Indemnitees and Related 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 

3

limitation, the warranty disclaimer provisions for the
benefit of Manufacturer, shall apply to and be binding upon Loan Trustee,
Noteholders, other Indenture Indemnitees and Related 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.

          Subject
to the terms and conditions hereof, 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 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.

extent permitted by law, any overdue Make-Whole Amount, if any, any overdue
interest and any other overdue amounts hereunder) to the date of such payment;
second, to the payment of Make-Whole Amount, if any; third, to the

portion thereof) remaining unpaid in the inverse order of their maturity.  

          This

          Section
2.02 Issuance and Terms of Equipment Notes. The Equipment Notes (other
than the Additional Series Equipment Notes) shall be dated the date of issuance
thereof, shall be issued in (a) separate Series consisting of
Series A Equipment Notes, Series B Equipment Notes and Series C 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 A Equipment Note, Series B Equipment Note and Series C
Equipment Note shall be issued to Subordination Agent on behalf of each of Pass
Through Trustees for the applicable Pass Through Trust created under the Pass
Through Trust Agreements referred to in Schedule II. Subject to the conditions
set forth in Section 4(a)(v) of the Note Purchase Agreement and Section 8.01(d)
of the Intercreditor Agreement, Company shall have the option to issue
Additional Series Equipment Notes at any time and from time to time. The
Additional Series Equipment Notes may be issued in an unlimited number of
separate series (if more than one series of Additional Series Equipment Notes
are so issued, each such series shall have a different designation such as, for
example, “Series D” and “Series E”), shall be dated the date of original
issuance thereof and shall have such maturities, principal amounts and interest
rates as specified in an amendment to this Indenture. 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. Without limitation of the foregoing, new Series B Equipment
Notes, Series C Equipment Notes or Additional Series Equipment Notes may be
issued pursuant to the provisions of Section 2.11(b).

          Each
Equipment Note shall bear interest at the Debt Rate (calculated on the basis of
a year of 360 days comprised of twelve 30-day months), 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 A Equipment Note, each

11

Series B Equipment Note and each Series C
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. Each Additional Series Equipment Note, if
issued, shall be payable in installments or in a single payment as set forth in
an amendment to this Indenture, and if payable in installments, such
installments shall be calculated as set forth in the second preceding sentence.
Notwithstanding the foregoing, the final payment made under each 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 comprised of twelve 30-day months) 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 herein
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 if such payment is made on such
next succeeding Business Day, no interest shall accrue on the amount of such
payment from and after such scheduled date.

          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.

          The
aggregate principal amount of any Series of Equipment Notes issued hereunder
shall not exceed the amount set forth as the maximum therefor on Schedule I
hereto (as amended, in the case of any Additional Series, at the time of
original issuance of such Additional Series).

12

          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 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, and payment of such amount by Company to Loan
Trustee shall be deemed to satisfy Company’s obligation to make such payment.
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 shall, unless instructed by
Company to use another method, 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 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. So long as any signatory to the Participation Agreement or nominee
thereof shall be a registered Noteholder, all payments to it shall be made to
the account of such Noteholder specified in Schedule I thereto and otherwise in
the manner provided in or pursuant to the Participation Agreement unless it
shall have specified some other account or manner of payment by notice to Loan
Trustee consistent with this Section 2.03.

13

          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, and
interest paid thereon shall be applied:

	
 

	
 

	
 

	
          first,
 to the payment of accrued interest on such Equipment Note (as well as any
 interest on (i) any overdue principal amount, and (ii) 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; 

	
 

	
 

	
 

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

	
 

	
 

	
 

	
          third,
 to the payment of the principal amount of such Equipment Note (or portion
 thereof) then due; and 

	
 

	
 

	
 

	
          fourth,
 the balance, if any, remaining thereafter, to the payment of installments of
 the principal amount of such Equipment Note (or portion thereof) remaining
 unpaid in the inverse order of their maturity.

          Section
2.06 Termination of Interest in Collateral. No Noteholder, Indenture
Indemnitee or Related 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
post-petition interest and interest on any overdue amounts) on and all other
amounts due under all Equipment Notes held by such Noteholder and all other
sums then due and payable to such Noteholder or Indenture Indemnitee, as the
case may be, hereunder (including, without limitation, under Section 

14

2.14) and
under the Participation Agreement by Company and (ii) all Related
Secured Obligations ((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 as
herein provided. 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 (if so required by Company or Loan Trustee) 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 Company and Loan Trustee shall require evidence
satisfactory to it as to the compliance of any such transfer with the
Securities Act 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 

15

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
transfer of an Equipment Note. Any such transferee of an Equipment Note, by its
acceptance of an Equipment Note, agrees to the provisions of the Indenture, the
Related Indentures, the Participation Agreement, the other Operative Documents
and the Pass Through Documents applicable to Noteholders or, in the case of

          Section

          Section
3.07 Securities Account. In furtherance of the provisions of Section
3.03 of this Indenture, U.S. Bank agrees to act as an Eligible Institution
under the Indenture in accordance with the provisions of this Indenture (in
such capacity, the “Securities Intermediary”). Except in its capacity as
Loan Trustee, U.S. Bank waives any claim or lien against any Eligible Account
it may have, by operation of law or otherwise, for any amount owed to it by
Company. The Securities Intermediary hereby agrees that, notwithstanding anything
to the contrary in this Indenture, (i) any amounts to be held by Loan
Trustee pursuant to paragraph (xi) or (xvii) of clause “third” of Section 3.03
and any investment earnings thereon or other Permitted Investments in which
such amounts are invested will be credited to an Eligible Account (the “Securities
Account”) for which it is a “securities intermediary” (as defined in
Section 8-102(a)(14) of the NY UCC) and Loan Trustee is the “entitlement
holder” (as defined in Section 8-102(a)(7) of the NY UCC) of the “securities
entitlement” (as defined in Section 8-102(a)(17) of the NY UCC) with respect to
each “financial asset” (as defined in Section 8-102(a)(9) of the NY UCC)
credited to such Eligible Account, (ii) all such amounts, Permitted
Investments and all 

34

other property acquired with cash credited to the
Securities Account will be credited to the Securities Account, (iii) all
items of property (whether cash, investment property, Permitted Investments,
other investments, securities, instruments or other property) credited to the
Securities Account will be treated as a “financial asset” under Article 8 of
the NY UCC, (iv) its “securities intermediary’s jurisdiction” (as
defined in Section 8-110(e) of the NY UCC) with respect to the Securities
Account is the State of New York, and (v) all securities, instruments
and other property in order or registered form and credited to the Securities
Account shall be payable to or to the order of, or registered in the name of,
the Securities Intermediary or shall be indorsed to the Securities Intermediary
or in blank, and in no case whatsoever shall any financial asset credited to
the Securities Account be registered in the name of Company, payable to or to
the order of Company or specially indorsed to Company except to the extent the
foregoing have been specially endorsed by Company to the Securities
Intermediary or in blank. Loan Trustee agrees that it will hold (and will
indicate clearly in its books and records that it holds) its “securities
entitlement” to the “financial assets” credited to the Securities Account in
trust for the benefit of Noteholders, each Indenture Indemnitee and each
Related Indenture Indemnitee as set forth in this Indenture. Company
acknowledges that, by reason of Loan Trustee being the “entitlement holder” in
respect of the Securities Account as provided above, Loan Trustee shall have
the sole right and discretion, subject only to the terms of this Indenture, to
give all “entitlement orders” (as defined in Section 8-102(a)(8) of the NY UCC)
with respect to the Securities Account and any and all financial assets and
other property credited thereto to the exclusion of Company. If any Person
asserts any Lien (including, without limitation, any writ, garnishment,
judgment, warrant of attachment, execution or similar process) against the
Securities Account or any financial asset carried therein, U.S. Bank will
promptly notify Loan Trustee and Company thereof.

with the requirements of, applicable law then in
effect (provided 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 CRAF 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

          (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,
 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 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

          (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 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 

38

	
 

	
 

	
 

	
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); provided that, notwithstanding anything to the contrary set
 forth herein or in any other Operative Document, (i) as permitted by
 Article 15 of the Cape Town Convention, the provisions of Chapter III of the
 Cape Town Convention are hereby excluded and made inapplicable to this
 Indenture and the other Operative Documents, except for those provisions of
 such Chapter III that cannot be derogated from; and (ii) as permitted
 by Article IV(3) of the Aircraft Protocol, the provisions of Chapter II of
 the Aircraft Protocol are hereby excluded and made inapplicable to this
 Indenture and the other Operative Documents, except for (x) Article
 XVI of the Aircraft Protocol and (y) those provisions of such Chapter
 II that cannot be derogated from. In furtherance of the foregoing, the
 parties hereto agree that the exercise of remedies hereunder and the other
 Operative Documents is subject to other applicable law, including without
 limitation, the Uniform Commercial Code (as in effect in the State of New
 York) and the Bankruptcy Code, and that nothing herein derogates from the
 rights of Company or Loan Trustee under or pursuant to such other applicable
 law, including without limitation, the Uniform Commercial Code (as in effect
 in the State of New York) or the Bankruptcy Code.

          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, 

39

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 may seek 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 judgment 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 party 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 

40

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 reasonably 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, or all Equipment Notes
shall have become due and payable as provided in the proviso to Section
4.02(a)(i), and, in either case, 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 or
deemed declaration, 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
rescission or annulment shall extend to or affect any subsequent default or
Event of Default or impair any right consequent thereon.

          (e)
Notwithstanding anything contained herein, (i) 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, and (ii) Loan Trustee will not take any action that would
violate Sections 4.01(a)(ii) or 4.01(a)(iii) of the Intercreditor Agreement.

          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 

41

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 this Indenture and the other Operative Documents,
but no such waiver shall extend to any subsequent or other default or impair
any right consequent thereon; provided 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, 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:

	
 

	
 

	
 

	
          (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;

42

	
 

	
 

	
 

	
          (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. To the extent permitted by applicable
law, 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, to the extent permitted by applicable law, 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.

ARTICLE V

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, or Make-Whole Amount, if any,
due and payable under any Equipment Note, Loan Trustee shall promptly give
notice thereof to Company, each Liquidity Provider and each Noteholder. Subject
to the 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 

43

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 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 permitted hereunder,
in each case, 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.

          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 actually 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.

44

          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 amounts held by Loan Trustee pursuant
to Section 3.02, 3.03 or 3.07 or pursuant to any provision of any other
Operative Document providing for amounts to be held by Loan Trustee which are
not distributed pursuant to the other provisions of Article III, or 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. All Permitted Investments held
by Loan Trustee pursuant to this Section 5.06 shall either be (i)
registered in the name of, payable to the order of, or 

45

specially endorsed to, Loan Trustee or (ii)
held in an Eligible Account. 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 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, 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.

6.04 No Segregation of Monies; No Interest. Subject to Section 5.06 and
except as provided in Section 3.07, 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 received by it hereunder; provided that any payments received, or
applied hereunder, by Loan Trustee shall be accounted for by Loan Trustee so
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; provided that, prior to retaining
agents (including paying agents or registrars), counsel, accountants or other
skilled Persons, so long as no Event of Default exists, Loan Trustee shall
obtain 

47

Company’s consent (such consent not to be unreasonably
withheld). 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.

          (i)
 subject the Airframe to interchange agreements or subject any Engine to

 by Company (or any Permitted Lessee) in the ordinary course of its business; provided
 that (A) no such agreement or arrangement contemplates or
 requires the transfer of title to the Airframe and (B) if

 promptly notify Loan Trustee upon transferring possession of the Airframe or
 any Engine pursuant to this clause (iv) and (B) in the case
 of a transfer of possession pursuant to the CRAF Program, shall notify Loan

 or claims must be made to the extent applicable under the CRAF Program;

	
 

	
 

	
 

	
          (v)
 install an Engine on an airframe owned by Company (or any Permitted Lessee)
 free and clear of all Liens, except (A) Permitted Liens and Liens
 that apply only to the engines (other than Engines), appliances, parts,
 instruments, appurtenances, accessories, furnishings and other equipment
 (other than Parts) installed on such airframe (but not to the airframe as an
 entirety) and (B) the rights of third parties under interchange

 or purchased or owned by Company (or any Permitted Lessee) subject to a
 conditional sale or other security agreement; provided that: (A) such

 other security agreement covering such airframe), in form and substance
 satisfactory to Loan Trustee (an agreement from such lessor or secured party
 substantially in the form of the penultimate paragraph of this Section
 7.02(a) being deemed to be satisfactory to Loan Trustee), whereby such lessor
 or secured party expressly agrees that neither it nor its successors or
 assigns will acquire or claim any right, title or interest in any Engine by
 reason of such Engine being 

50

	
 

	
 

	
 

	
installed on such airframe at any time while such
 Engine is subject to the Lien of this Indenture, or (2) such
 lease, conditional sale or other security agreement provides that such Engine

          (vii)
 install an Engine on an airframe owned by Company (or any Permitted Lessee),

 Permitted Lessee) subject to a 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 Section 7.05(b) in respect thereof, if such installation
 adversely affects Loan Trustee’s security interest in such Engine, Loan
 Trustee not intending hereby to waive any right or interest it may have to or
 in such Engine under applicable law until compliance by Company with Section
 7.05(b);

	
 

	
 

	
 

	
          (viii)
 lease any Engine or the Airframe and Engines to any United States air carrier
 as to which there is in force a certificate issued pursuant to the
 Transportation Code (49 U.S.C. Sections 41101-41112) or successor provision
 that gives like authority; provided that no Event of Default exists at
 the time such lease is 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 Applicable 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 then rated by
 such Applicable Rating Agency or a withdrawal or suspension of the rating of
 any class of Pass Through Certificates 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 

51

	
 

	
 

	
 

	
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 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 

52

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 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
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 

53

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).

          (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 shall have received at the time of such
registration an opinion of counsel to Company 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 

54

Lien of this Indenture shall continue as a valid 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 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 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 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):

55

	
 

	
 

	
 

	
          (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; and

	
 

	
 

	
 

	
          (iv) 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.

          Company shall
(i) at Loan Trustee’s request from time to time, take such actions as
may be required to be taken by Company so that any International Interest
arising in relation to this Indenture, the Aircraft, any Replacement Aircraft,
any Engine or Replacement Engine may be duly registered (and any such
registration may be assigned, amended, extended or discharged) at the
International Registry, and (ii) obtain from the International Registry
all approvals as may be required duly and timely to perform Company’s
obligations under this Indenture with respect to the registration of any such
International Interest. Loan Trustee shall take all actions necessary with
respect to the International Registry to consent to Company’s initiation of any
registrations required under this Indenture to enable Company to complete such
registrations, including, without limitation, appointing Daugherty, Fowler,
Peregrin, Haught & Jenson, a Professional Corporation, as its “professional
user entity” (as defined in the Cape Town Treaty) to consent to any
registrations on the International Registry with respect to the Airframe or any
Engine. 

          Section 7.03 Inspection; Financial Information.

          (a) Inspection. At all reasonable times, but upon at least 15 Business Days’
prior written notice to Company, Loan Trustee or its 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) Loan Trustee or its representatives, as the

56

case may be, shall be fully insured at no cost to
Company or any Permitted Lessee 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 and any Permitted
Lessee with respect to such risks, (ii) any such inspection shall
be during Company’s or Permitted Lessee’s, as the case may be, 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 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 or any Permitted Lessee and Company and any Permitted
Lessee 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 Loan Trustee and its 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 Loan Trustee (or its
representatives) making such inspection. Except during the continuance of an
Event of Default, all inspections by Loan Trustee and its representatives
provided for under this Section 7.03(a) shall be limited to one inspection of

          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. 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 

58

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 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 materially adversely affect Loan Trustee’s interest in the Aircraft. 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 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. Loan Trustee acknowledges that it has no interest
in the Excluded Equipment. Notwithstanding the provisions of this Section
7.04(c) or any other term or condition of this Indenture, Company (or any
Permitted Lessee) may from time to 

59

time install on, and remove from, the Aircraft
equipment that is owned by, leased to or conditionally sold to Company (or any
Permitted Lessee) (and title to such equipment shall remain vested in Company,
such Permitted Lessee, or the lessor or the conditional vendor thereof) if (1) such
equipment is Excluded Equipment and (2) the location affected by any such removal, if
damaged, is repaired prior to return, in a workmanlike manner, to a condition
suitable for commercial passenger service; provided that all
costs of installation, removal and replacement shall be the responsibility of
Company.

          (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.

60

          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.

          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 the sale of such Replacement Airframe and Replacement Engines, if any, to
Company (if occurring after February 28, 2006 and if the seller of such
Replacement Airframe and Replacement Engines, if any, is “situated in” a
country that has ratified the Cape Town Convention) and the International
Interest created pursuant to the Indenture Supplement in favor of Loan Trustee
with respect to such Replacement Airframe and Replacement Engines, if any, each
to be registered on the International Registry as a sale or an International
Interest, respectively; provided that if the seller of such Replacement
Airframe and Replacement Engines, if any, is not situated in a country that has
ratified the Cape Town Convention, Company will use its best efforts to cause
the seller to register the contract of sale on the International Registry, (C)
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, (D) 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), (B) and (C), (E) furnish Loan Trustee with a
certificate of an independent aircraft engineer or appraiser, certifying 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, (F) 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, (G) 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 (H) 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 

61

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 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 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 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 (H) 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

62

Company all
claims against third Persons for damage to or loss of the Aircraft arising from
the Event of Loss, and will take such actions as may be required to be taken by
Loan Trustee to cancel or release any International Interest of Loan Trustee
registered with the International Registry in relation to the Airframe and
Engines, if any, with respect to which such Event of Loss occurred.

          (b)
Event of Loss with Respect to an Engine. As soon as practicable
following 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, which in the case of any such conveyance to which the Cape
Town Convention is applicable shall be in such form as will qualify as “contract
of sale” pursuant to Article V of the Aircraft Protocol, and all documents
required under the Operative Documents to establish, continue, confirm,
register and/or perfect the interests of Loan Trustee in such Replacement
Engine, (iii) cause the sale of such Replacement Engine to Company (if
occurring after February 28, 2006 and if the seller of such Replacement
Engine is “situated in” a country that has ratified the Cape Town Convention)
and the International Interest created pursuant to the Indenture Supplement in
favor of Loan Trustee with respect to such Replacement Engine, each to be
registered on the International Registry as a sale or an International
Interest, respectively; provided that if the seller of such Replacement
Engine is not situated in a country that has ratified the Cape Town Convention,
Company will use its best efforts to cause the seller to register the contract
of sale on the International Registry, (iv) 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, (v) furnish
Loan Trustee with an opinion of Company’s counsel (which may be internal
counsel to Company) addressed to Loan Trustee to the effect that, upon such
replacement, the Replacement Engine will be subject to the Lien of this
Indenture, (vi) furnish Loan Trustee with a certificate of an
aircraft engineer or appraiser (who may be an employee of Company) certifying
that such

63

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 (vii) 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 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, the registration with the International
Registry of the sale of such Replacement Engine to Company (if occurring after
February 28, 2006) and of the International Interest created pursuant to
the Indenture Supplement with respect to such Replacement Engine 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 (vii) 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, and will take such actions as may be required to be taken by Loan Trustee
to cancel or release any International Interest of Loan Trustee registered with
the International Registry in relation to the Engines with respect to which
such Event of Loss occurred.

          (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 

64

	
 

	
 

	
 

	
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

	
 

	
 

	
 

	
          (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 or hire 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 or hire (it being
acknowledged that the use of the Airframe or any Engine pursuant to the CRAF
Program does not constitute such a requisition), 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

65

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 and the Participation Agreement. 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 Section 7.06(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(d), Company will carry, or
  cause to be carried, at no expense to Loan Trustee, aircraft liability
  insurance (including, but not limited to, passenger, contractual, bodily
  injury, personal injury and property damage liability (exclusive of
  manufacturer’s product liability insurance and war risk, hijacking and
  related perils insurance)) with respect to the Aircraft that is of the type
  as from time to time applicable to aircraft operated by Company (or, if a
  Lease in respect of the Aircraft is then in effect, by Permitted Lessee) of
  the same type as 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 and operated by
  Company on the same or similar routes as operated by the Aircraft; provided
  that such liability insurance shall not be less than the amount (the “Minimum
  Insurance Amount”) certified in the insurance report delivered to Loan
  Trustee and Liquidity Providers on the Closing Date, and (B) 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 policies shall: (1) name
  Loan Trustee, Subordination Agent, each Pass Through Trustee and each
  Liquidity Provider as their Interests (defined below in this Section 7.06)
  may appear, as additional insureds (the “Additional Insureds”), (2) subject
  to the conditions of clause (3) below, provide that, in respect of the
  interest of each Additional Insured in such policies, the insurance shall not
  be invalidated by any action or inaction of Company or any other Person
  (other than such Additional Insured) and shall insure each Additional Insured’s
  Interests as they appear, regardless of any breach or violation of any
  warranty, declaration or condition contained in such policies by Company or
  any other Person (other than such Additional Insured), (3) provide
  that, if such insurance is canceled for any reason, or if any change is made
  in the insurance that materially reduces the amount of insurance or the
  coverage certified in the insurance report delivered on the Closing Date to
  Loan Trustee 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 after receipt by

66

	
 

	
 

	
 

	
such
  Additional Insured of written notice from such insurers of such cancellation,
  change or lapse, (4) provide that the Additional Insureds shall
  have no obligation or liability for premiums, commissions, assessments or
  calls in connection with such insurance, (5) provide that the
  insurers shall waive any rights of (x) 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 (y) 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, (6) 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
  (7) 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 Sections 7.06(b) and 7.06(c) with respect to any
  Person means the interests of such Person in the transactions contemplated by
  the Operative Documents.

	
 

	
 

	
 

	
          (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 Section 7.06(d) below, 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.

          (b)
War Risk, Hijacking and Related Perils Liability Insurance. If the
Aircraft, the Airframe or any Engine is being operated in any war zone or area
of recognized or, in Company’s judgment, threatened hostilities, then Company
shall maintain or cause to be maintained war risk, hijacking and related perils
liability insurance (x) in an amount that is not less than the aircraft
liability insurance applicable to similar aircraft and engines in Company’s
fleet on which Company carries insurance and operated by Company on the same or
similar routes as the Aircraft, the Airframe or such Engine; provided
that such liability insurance shall not be less than the Minimum Insurance
Amount, (y) that is maintained in effect with insurers of recognized
responsibility, and (z) which shall cover the perils set forth in the
insurance policies maintained in connection with the CRAF Program (as such
insurance policies maintained

67

in connection with the CRAF
Program may be amended from time to time). Except with respect to any war-risk,
hijacking or related perils liability insurance maintained on any aircraft
owned or operated by Company in connection with the CRAF Program, if war-risk,
hijacking or related perils insurance is maintained by Company with respect to
any aircraft owned or operated by Company of the same or similar type operated
by Company on the same or similar routes as operated by the Aircraft, the
Airframe or such Engine, then Company shall maintain or cause to be maintained
with respect to the Aircraft war-risk, hijacking and related perils liability
insurance in scope and coverage no less comprehensive, in an amount not less
than the insurance maintained by Company with respect to such other aircraft,
and with insurers of recognized responsibility. Any policies of insurance
carried in accordance with this Section 7.06(b) and any policies taken out in
substitution or replacement for any of such policies shall: (1) name
Loan Trustee, Subordination Agent, each Pass Through Trustee and each Liquidity
Provider as their Interests may appear, as Additional Insureds, (2)
subject to the conditions of clause (3) below (other than the exception set
forth therein), provide that, in respect of the interest of each Additional
Insured in such policies, the insurance shall not be invalidated by any action
or inaction of Company or any other Person (other than such Additional Insured)
and shall insure each Additional Insured’s Interests as they appear, regardless
of any breach or violation of any warranty, declaration or condition contained
in such policies by Company or any other Person (other than such Additional
Insured), (3) provide that, except to the extent not provided for by
Company’s war risk and allied perils insurance provider, if such insurance is
canceled for any reason, or if any change is made in the insurance that
materially reduces the amount of insurance or the coverage certified in the
insurance report delivered on or prior to the Effective Date to Loan Trustee
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 seven days (or such other period as
is then generally available in the industry) after receipt by such Additional
Insured of written notice from such insurers of such cancellation, change or
lapse, (4) provide that the Additional Insureds shall have no obligation
or liability for premiums, commissions, assessments or calls in connection with
such insurance, (5) provide that the insurers shall waive any rights of
(x) 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 (y) 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, (6) 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 (7) 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. To the
extent that Company’s war-risk and allied perils insurance provider does not
provide for provision of direct notice to Additional Insureds of cancellation,
change or lapse in the insurance required hereunder, Company hereby agrees that
upon receipt of

68

notice of any thereof from such insurance provider it
shall give the Additional Insureds immediate notice of each cancellation or
lapse of, or change to, such insurance.

          (c)
Insurance Against Loss or Damage to Aircraft. 

	
 

	
 

	
 

	
          (i)
  Except as provided in clause (ii) of this Section 7.06(c), 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(d) below, 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 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(c) and any policies taken out in substitution or replacement for any
  such policies shall: (1) 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 Insurance Threshold up to an amount equal to 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 paid 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) up to an amount equal to
  the Loan Amount 

69

	
 

	
 

	
 

	
shall be payable to Loan Trustee, (2) subject
  to the conditions of clause (C) below (other than the exception set
  forth therein), provide that, in respect of the interest of each Additional
  Insured in such policies, the insurance shall not be invalidated by any
  action or inaction of Company or any other Person (other than such Additional
  Insured) and shall insure each Additional Insured’s Interests as they appear,
  regardless of any breach or violation of any warranty, declaration or
  condition contained in such policies by Company or any other Person (other
  than such Additional Insured), (3) provide that, except to the
  extent not provided for by Company’s hull war risk and allied perils
  insurance provider, 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, 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 then customary 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, (4) provide that the Additional Insureds shall have no
  obligation or liability for premiums, commissions, assessments or calls in
  connection with such insurance, (5) provide that the insurers
  shall waive rights of (x) setoff, 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 (y) 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 (6) 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. To
  the extent that Company’s war-risk and allied perils insurance provider does
  not provide for provision of direct notice to Additional Insureds of
  cancellation, change or lapse in the insurance required hereunder, Company
  hereby agrees that upon receipt of notice of any thereof from such insurance
  provider it shall give the Additional Insureds immediate notice of each
  cancellation or lapse of, or change to, such 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 Section 7.06(d) below, 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 are 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 

70

	
 

	
 

	
 

	
permitted by Section 7.06(d) below, 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.

          (d)
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 Sections
7.06(a), 7.06(b) or 7.06(c), insuring for a maximum amount that is less than
the amounts set forth in Sections 7.06(a), 7.06(b) and 7.06(c) above), the
risks required to be insured against pursuant to Sections 7.06(a), 7.06(b) and
7.06(c) above, but in no case shall the self-insurance with respect to all of
the aircraft and engines in the combined fleet of Company and its Affiliates
(including, without limitation, the Aircraft) exceed for any 12-month policy
year 1.0% of the average aggregate insurable value (during the preceding policy
year) of all aircraft (including, without limitation, the Aircraft) on which
Company and its Affiliates carry 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; provided that (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 shall be permitted in addition to the above-mentioned
self-insurance.

          (e)
Indemnification by United States Government in Lieu of Insurance.
Notwithstanding any provision of this Section 7.06 requiring insurance, in lieu
of insurance against any risk with respect to the Aircraft, indemnification
from, or insurance provided by, the United States government, or any agency or
instrumentality thereof, against such risk in an amount which, when added to the
amount of insurance maintained against such risk by Company (or, if a Lease is
then in effect, by the Permitted Lessee), shall be at least equal to the amount
of insurance against such risk otherwise required by this Section 7.06
(taking into account self-insurance permitted by Section 7.06(d)) shall be
considered adequate insurance for purposes of this Section 7.06.

          (f)
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 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:

71

	
 

	
 

	
 

	
          (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) or (ii) of the first paragraph of this Section
7.06(f) 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 the other Operative
Documents and shall be invested pursuant to Section 5.06 unless and until such
amount is applied, at the option of Loan Trustee, to Company’s obligations
under this Indenture and the other Operative Documents as and when due, it
being understood that any such application shall be made to such obligations of
Company as Loan Trustee may determine in its sole discretion. At such time as there
shall be continuing no Event of Default or Payment 

72

Default, such amount shall be paid to Company to the
extent not previously applied in accordance with this Section 7.06(f).

          (g)
Reports, Etc. On or before the Closing Date and annually following
renewal of Company’s insurance coverage, Company will furnish to Loan Trustee
and Liquidity Providers current certificates of insurance and 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 complies
with the terms hereof. All information contained in such report shall be
Confidential Information and shall be treated by Loan Trustee and Liquidity
Providers and each of their Affiliates and their respective officers,
directors, agents and employees in accordance with the provisions of Section
10.16. Company will cause such firm to notify Loan Trustee 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 and Liquidity Providers 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.

          In
the event that Company shall fail to maintain or to cause to be maintained
insurance as herein provided, Loan Trustee may at its option obtain such
insurance (giving Company prompt written notice thereof, but the failure to so
notify Company shall not in any way affect the rights of Loan Trustee
hereunder) and, in such event, Company shall, upon demand, reimburse Loan
Trustee for the cost to Loan Trustee of such insurance, together with interest
thereon at the Past Due Rate for the period commencing with the date such cost
was paid to the date of reimbursement; provided, however, that no
exercise by Loan Trustee of said option shall affect the provisions of this
Indenture, including the provisions that failure by Company to maintain the
prescribed insurance shall constitute an Event of Default.

          (e)
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.

ARTICLE VIII

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, 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 

74

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 bank, trust company or corporation into which Loan Trustee may be merged or
converted or with which it may be consolidated, or any bank, trust company or
corporation resulting from any merger, conversion or consolidation to which
Loan Trustee is a party, or any bank, trust company or 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 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 

75

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, to the extent permitted by applicable law,
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 insofar as they apply to Loan Trustee. The powers of
any 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, 

76

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). In any case, Company may remove an additional or
separate trustee in the manner set forth in Section 8.01.

ARTICLE IX

Amendments and
Waivers

          Section
9.01 Amendments to this Indenture without Consent of Holders. At any
time after the date hereof, Company and Loan Trustee may enter into one or more
agreements supplemental hereto without notice to or consent of any Noteholder,
Indenture Indemnitee or Related Indenture Indemnitee for any of the following
purposes: (i) to evidence the succession of another Person to Company
and the assumption by any such successor of the covenants of Company contained
in any Operative Documents pursuant to Section 6.02(e) of the Participation
Agreement; (ii) to cure any defect or inconsistency herein or in
the Equipment Notes, or to make any change not inconsistent with the provisions
hereof (provided that such change does not adversely affect the
interests of any Noteholder, any Indenture Indemnitee or any Related Indenture
Indemnitee in its capacity solely as Noteholder, any Indenture Indemnitee or
any Related Indenture Indemnitee, as the case may be); (iii) to
cure any ambiguity or correct any mistake; (iv) to evidence the
succession of a new trustee hereunder pursuant hereto or the removal of the
trustee hereunder or to provide for or facilitate the appointment of an

Trustee; (vi) to make any other provisions or amendments with
respect to matters or questions arising hereunder or under the Equipment Notes,
or to amend, modify or supplement any provision hereof or thereof, so long as
such action shall not adversely affect the interests of any Noteholder, any

institution may in its discretion decline to execute such document.

          Section

effects the Exchange Offer, the Company shall be entitled to close the Exchange
Offer twenty (20) business days after such commencement (provided that the
Company has accepted all the Certificates theretofore validly tendered and not
withdrawn in accordance with the terms of the Exchange Offer).  

Each Holder
participating in the Exchange Offer shall be required to represent to the
Company in writing that at the time of the consummation of the Exchange Offer
(i) any Exchange Certificates received by such Holder will be acquired in the
ordinary course of business, (ii) such Holder will have no arrangements or
understanding with any Person to participate in the distribution (within the
meaning of the 1933 Act) of the Exchange Certificates (iii) such Holder is not
affiliate of either the Company within the meaning of Rule 405 under the 1933
Act, (iv) if such Holder is not a broker dealer, that it is not engaged in and
does not intend to engage in, the distribution of the Exchange Certificates and
(v) if such Holder is a broker dealer, that it will receive Exchange
Certificates for its own account in exchange for Certificates that were
acquired as a result of market making activities or other trading activities
and that it will be required to acknowledge that it will deliver a prospectus
in connection with the resale of such Exchange Certificates.  

                    (b)
In the event that, with respect to any Class of Certificates, the Company
determines that the Exchange Offer Registration provided for in Section 2(a)
above is not available or may not be consummated as soon as practicable after
the last Exchange Date because it would violate applicable law or the
applicable interpretations of the Staff of the SEC, the Company shall, in lieu
of effecting the registration of the applicable Exchange Certificates 

6

pursuant to
the Exchange Offer Registration Statement and at no cost to the holders of the
applicable Certificates, (i) as promptly as practicable, file with the SEC a
shelf registration statement covering resales of the applicable Certificates
(the “Shelf Registration Statement”), (ii) use its reasonable best efforts to cause the Shelf Registration Statement
to be declared effective under the Securities Act by the 270th calendar day
after the Issuance Date and (iii) use its reasonable best efforts to keep
effective the Shelf Registration Statement for a period of two years after its
effective date (or for such shorter period as shall end when all of the
applicable Certificates covered by the Shelf Registration Statement have been
sold pursuant thereto or may be freely sold pursuant to Rule 144 under the
Securities Act).  The Company further
agrees to supplement or amend the Shelf Registration Statement if required by
the rules, regulations or instructions applicable to the registration form used
by the Company for such Shelf Registration Statement or by the 1933 Act or by
any other rules and regulations thereunder for shelf registration or if
reasonably requested by a Holder with respect to information relating to such
Holder, and to use its best efforts to cause any such amendment to become
effective and such Shelf Registration Statement to become usable as soon as
thereafter practicable. The Company agrees to furnish to the Holders of
Registrable Certificates copies of any such supplement or amendment promptly
after its being used or filed with the SEC. 

                    (c)
Each Holder agrees that if the Certificates do not have an Investment Grade
Rating and the Holder is (i) an affiliate of the Company or the applicable
Trust, or a broker-dealer selling or otherwise transferring Certificates
acquired directly from the Company for its own account, or (ii) an underwriter
as defined in Section 2(a)(11) of the 1933 Act, such Holder (a) may not resell
or otherwise transfer such Certificate under a Shelf Registration Statement,
(b) may only offer, sell or otherwise transfer such Certificates to qualified
institutional buyers within the meaning of Rule 144A of the rules and
regulations promulgated under the 1933 Act, and (c) with respect to the Class C
Certificates, may only offer, sell or otherwise transfer such Certificates in
accordance with the proper transfer restrictions. 

                    (d)
The Company shall pay all Registration Expenses in connection with the
registration pursuant to Section 2(a) and Section 2(b).  Each Holder shall pay all underwriting
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder’s Registrable Certificates pursuant to the Shelf
Registration Statement. 

                    (e)
An Exchange Offer Registration Statement pursuant to Section 2(a) hereof or a
Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed
to have become effective unless it has been declared effective by the SEC; provided,
however, that, if, after it has been declared effective, the offering of
Registrable Certificates pursuant to a Shelf Registration Statement is
interfered with by any stop order, injunction or other order or requirement of
the SEC or any other governmental agency or court, such Registration Statement
will be deemed not to have become effective during the period of such
interference until the offering of Registrable Certificates pursuant to such
Registration Statement may legally resume.
As provided for in the Pass Through Trust Agreements, in the event the
Exchange Offer is not consummated or the Shelf Registration Statement is not
declared effective on or prior to the 270th day (or, if such 270th
day is not a business day, the first business day thereafter) after the
Issuance Date, the interest rate on the applicable Certificates will be
increased by 0.50% per annum until the Exchange Offer is consummated or the
Shelf Registration Statement is declared  

7

effective by
the SEC. If the Shelf Registration Statement ceases to be effective for more
than 60 days, whether or not consecutive, during any 12- month period, the
interest rate per annum borne by the applicable Certificates shall be increased
by 0.50% from the 61st day until such time as the Shelf Registration Statement
again becomes effective. 

                    (f)
Without limiting the remedies available to the Initial Purchasers and the
Holders, the Company acknowledges that any failure by the Company to comply
with its obligations under Section 2(a) and Section 2(b) hereof may result in
material irreparable injury to the Initial Purchasers or the Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Initial Purchasers or any Holder may obtain such relief as may be required
to specifically enforce the Company’s obligations under Section 2(a) and
Section 2(b) hereof. 

                    3. Registration
Procedures. 

                    In
connection with the obligations of the Company with respect to the Registration

 form and include all financial statements required by the SEC to be filed

 Statement to become effective and remain effective in accordance with Section
 2 hereof; 

	
 

	
 

	
 

	
          (b)

 keep each Prospectus current during the period described under Section 4(3)
 and Rule 174 under the 1933 Act that is applicable to transactions by brokers
 or dealers with respect to the Registrable Certificates or Exchange
 Certificates; 

	
 

	
 

	
 

	
          (c)
 in the case of a Shelf Registration, furnish to each Holder of Registrable
 Certificates, to counsel for the Initial Purchasers, to counsel for the

 applicable law by each of the selling Holders of Registrable Certificates and
 any such Underwriters in connection with the offering and sale of the

manner
 described in such Prospectus or any amendment or supplement thereto in
 accordance with applicable law; 

	
 

	
 

	
 

	
          (d)
 use its reasonable best efforts to register or qualify the Registrable
 Certificates under all applicable state securities or “blue sky” laws of such
 jurisdictions as any Holder of Registrable Certificates covered by a
 Registration Statement shall reasonably request in writing by the time the
 applicable Registration Statement is declared effective by the SEC, to
 cooperate with such Holders in connection with any filings required to be
 made with the National Association of Securities Dealers, Inc. and do any and
 all other acts and things which may be reasonably necessary or advisable to
 enable such Holder to consummate the disposition in each such jurisdiction of
 such Registrable Certificates owned by such Holder; provided, however,
 that the Company shall not be required to (i) qualify as a foreign
 corporation or as a dealer in securities in any jurisdiction where it would
 not otherwise be required to qualify but for this Section 3(d), (ii) file any
 general consent to service of process or (iii) subject itself to taxation in
 any such jurisdiction if it is not so subject; 

	
 

	
 

	
 

	
          (e)
 in the case of a Shelf Registration, notify each Holder of Registrable
 Certificates who has provided contact information to the Company, counsel for
 the Holders and counsel for the Initial Purchasers promptly and, if requested
 by any such Holder or counsel, confirm such advice in writing (i) when a
 Shelf Registration Statement has become effective and when any post-effective
 amendment thereto has been filed and becomes effective, (ii) of any request
 by the SEC or any state securities authority for amendments and supplements
 to a Shelf Registration Statement and Prospectus or for material additional
 information after the Shelf Registration Statement has become effective,
 (iii) of the issuance by the SEC or any state securities authority of any
 stop order suspending the effectiveness of a Shelf Registration Statement or
 the initiation of any proceedings for that purpose, (iv) if, between the
 effective date of a Shelf Registration Statement and the closing of any sale
 of Registrable Certificates covered thereby, the representations and
 warranties of the Company contained in any underwriting agreement, securities
 sales agreement or other similar agreement, if any, relating to the offering
 cease to be true and correct in all material respects or if the Company
 receives any notification with respect to the suspension of the qualification
 of the Registrable Certificates for sale in any jurisdiction or the
 initiation of any proceeding for such purpose, (v) of the happening of any
 event during the period a Shelf Registration Statement is effective which
 makes any statement made in such Shelf Registration Statement or the related
 Prospectus untrue in any material respect or which requires the making of any
 changes in such Shelf Registration Statement or Prospectus in order to make
 the statements therein (in the case of the Prospectus, in he light of the
 circumstances under which they were made) not misleading and (vi) of any
 determination by the Company that a post-effective amendment to a
 Registration Statement would be appropriate; 

	
 

	
 

	
 

	
          (f)
 make every reasonable effort to obtain the withdrawal of any order suspending
 the effectiveness of a Registration Statement at the earliest possible moment
 and provide immediate notice to each Holder of the withdrawal of any such
 order; 

9

	
 

	
 

	
 

	
          (g)
in the case of a Shelf Registration, furnish to each Holder of
Registrable Certificates, without charge, at least one conformed copy of each
Shelf Registration Statement and any post-effective amendment thereto
(without documents incorporated therein by reference or exhibits thereto,
unless requested);  

	
 

	
 

	
 

	
          (h)
 in the case of a Shelf Registration, cooperate with the selling
 Holders of Registrable Certificates to facilitate the timely preparation and
 delivery of certificates representing Registrable Certificates to be sold
 and, in the case of the Class A Certificates and the Class B Certificates,
 not bearing any restrictive legends, and enable such Registrable Certificates
 to be in such denominations (consistent with the provisions of the Pass
 Through Trust Agreements) and registered in such names as the selling Holders
 may reasonably request at least two business days prior to the closing of any
 sale of Registrable Certificates; 

	
 

	
 

	
 

	
          (i)
in the case of a Shelf Registration, upon the occurrence of any event
contemplated by Section 3(e)(v) hereof, use its reasonable best efforts to
prepare and file with the SEC a supplement or post-effective amendment to a
Shelf Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable
Certificates, such Prospectus will not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The Company agrees to notify the Holders to suspend use
of the Prospectus as promptly as practicable after the occurrence of such an
event, and the Holders hereby agree to suspend use of the Prospectus until
the Company has amended or supplemented the Prospectus to correct such
misstatement or omission;  

	
 

	
 

	
 

	
          (j)

 Purchasers or their counsel (and, in the case of a Shelf Registration

 Indenture Act of 1939, as amended (the “TIA”), in connection with the
 registration of the Exchange Certificates or Registrable Certificates, as the
 case may be, cooperate with the Trustee and the Holders to effect such
 changes to the Pass Through Trust Agreements as may be required for the Pass
 Through Trust Agreements to be so qualified in accordance with the terms of the

          (m)

Underwriter participating in any disposition pursuant to such Shelf
Registration Statement, and attorneys and accountants designated by the
Holders, at reasonable times and in a reasonable manner, all financial and
other records, pertinent documents and properties of the Company, and cause
the respective officers, directors and employees of the Company to supply all
information reasonably requested by any such representative, Underwriter,
attorney or accountant in connection with a Shelf Registration Statement;
provided, however, that any records, information or documents that are
reasonably designated by the Company as confidential at the time of delivery
of such records, information or documents shall be kept confidential by such
persons, unless (i) such records, information or documents are in the public
domain or otherwise publicly available, (ii) disclosure of such records,
information or documents is required by court or administrative order or is
necessary to respond to inquiries of regulatory authorities, (subject to the
requirements of such order, and only after such person shall have given the

such requirements so that the Company, at its expense, may undertake

the confidentiality of such records, information or documents), (iii)

(including any disclosure requirements pursuant to federal securities laws in
connection with the filing of any Registration Statement or the use of any

          (n)
 use its reasonable best efforts to cause the Registrable Certificates or the
 Exchange Certificates, as the case may be, with respect to the Class A
 Certificates and the Class B Certificates, to continue to be rated by two
 nationally recognized statistical rating organizations (as such term is
 defined in Rule 436(g)(2) under the 1933 Act); 

11

	
 

	
 

	
 

	
          (o)
 if reasonably requested by any Holder of Registrable Certificates covered by
 a Registration Statement, (i) promptly incorporate in a Prospectus supplement
 or post-effective amendment such information with respect to such Holder as
 such Holder reasonably requests to be included therein and (ii) make all required
 filings of such Prospectus supplement or such post-effective amendment as
 soon as the Company has received notification of the matters to be
 incorporated in such filing; and 

	
 

	
 

	
 

	
          (p)
 in the case of a Shelf Registration, enter into such customary agreements and
 take all such other actions in connection therewith (including those
 requested by the Holders of a majority of the Registrable Certificates being
 sold) in order to expedite or facilitate the disposition of such Registrable
 Certificates including, but not limited to, an Underwritten Offering and in
 such connection, (i) to the extent possible, make such representations and
 warranties to the Holders and any Underwriters of such Registrable
 Certificates with respect to the business of the Company and its
 subsidiaries, the Registration Statement, Prospectus and documents
 incorporated by reference or deemed incorporated by reference, if any, in
 each case, in form, substance and scope as are customarily made by issuers to
 underwriters in underwritten offerings and confirm the same if and when
 requested, (ii) obtain opinions of counsel to the Company (which counsel and
 opinions, in form, scope and substance, shall be reasonably satisfactory to
 the Holders of a majority in principal amount of Registrable Certificates
 being sold and such Underwriters and their respective counsel) addressed to
 each selling Holder and Underwriter of Registrable Certificates, covering the
 matters customarily covered in opinions requested in connection with
 underwritten firm commitment offerings, (iii) obtain “cold comfort” letters
 from the independent certified public accountants of the Company (and, if
 necessary, any other certified public accountant of any subsidiary of the
 Company, or of any business acquired by the Company for which financial
 statements and financial data are or are required to be included in the
 Registration Statement) addressed to each selling Holder and Underwriter of
 Registrable Certificates, such letters to be in customary form and covering
 matters of the type customarily covered in “cold comfort” letters in
 connection with underwritten firm commitment offerings, and (iv) deliver such
 documents and certificates as may be reasonably requested by the Holders of a
 majority in principal amount of the Registrable Certificates being sold or
 the Underwriters, and which are customarily delivered in underwritten
 offerings, to evidence the continued validity of the representations and
 warranties of the Company made pursuant to clause (i) above and to evidence
 compliance with any customary conditions contained in an underwriting
 agreement. 

                    In
the case of a Shelf Registration Statement, the Company may require each Holder
of Registrable Certificates to furnish to the Company such information
regarding the Holder and the proposed distribution by such Holder of such
Registrable Certificates as the Company may from time to time reasonably
request in writing. The Company may exclude from such registrations the
Registrable Certificate of any Holder who fails to furnish such information
within 30 days after receiving such request. 

                    In
the case of a Shelf Registration Statement, each Holder agrees that,
upon receipt of any notice from the Company of the happening of any event of
the kind described in 

12

Section
3(e)(v) hereof, such Holder will forthwith discontinue disposition of
Registrable Certificates pursuant to a Shelf Registration Statement until such
Holder’s receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof, and, if so directed by the Company, such
Holder will deliver to the Company (at its expense) all copies in its
possession, other than permanent file copies then in such Holder’s possession,
of the Prospectus covering such Registrable Certificates current at the time of
receipt of such notice. If the Company shall give any such notice to suspend
the disposition of Registrable Certificates pursuant to a Registration
Statement, the Company shall extend the period during which the Registration
Statement shall be maintained effective pursuant to this Agreement by the
number of days during the period from and including the date of the giving of
such notice to and including the date when the Holders shall have received copies
of the supplemented or amended Prospectus necessary to resume such
dispositions. The Company may give any such notice only twice during any
365-day period and any such suspensions may not exceed 45 days for each
suspension and there may not be more than two suspensions in effect during any
365-day period. 

                    The
Holders of Registrable Certificates covered by a Shelf Registration Statement
who desire to do so may sell such Registrable Certificates in an Underwritten
Offering. In any such Underwritten Offering, the investment banker or
investment bankers and manager or managers (the “Underwriters”) that will
administer the offering will be selected by the Majority Holders of the
Registrable Certificates included in such offering, subject to the consent of
the Company (which shall not be unreasonably withheld). 

                    4. Participation
of Broker-Dealers in Exchange Offer. 

                    (a)
The Staff of the SEC has taken the position that any broker-dealer that
receives Exchange Certificates for its own account in the Exchange Offer in
exchange for Certificates that were acquired by such broker-dealer as a result
of market-making or other trading activities (a “Participating Broker-Dealer”),
may be deemed to be an “underwriter” within the meaning of the 1933 Act and
must deliver a prospectus meeting the requirements of the 1933 Act in
connection with any resale of such Exchange Certificates. 

                    The
Company understands that it is the Staff’s position that if the Prospectus
contained in the Exchange Offer Registration Statement includes a plan of
distribution containing a statement to the above effect and the means by which
Participating Broker-Dealers may resell the Exchange Certificates, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Certificates owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Certificates for their own accounts,
so long as the Prospectus otherwise meets the requirements of the 1933 Act. 

                    (b)
In light of Section 4(a), notwithstanding the other provisions of this
Agreement, the Company agrees that the provisions of this Agreement as they
relate to a Shelf Registration shall also apply to an Exchange Offer
Registration to the extent, and with such reasonable modifications thereto as
may be, reasonably requested by the Initial Purchasers or by one or more Participating
Broker-Dealers, in each case as provided in clause (ii) below, in order 

13

to expedite or
facilitate the disposition of any Exchange Certificates by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section 4(a)
above; provided that:  

	
 

	
 

	
 

	
          (i)
 the Company shall not be required to amend or supplement the Prospectus
 contained in the Exchange Offer Registration Statement, as would otherwise be
 contemplated by Section 3(i), (A) after the Participating Broker-Dealers
 shall have disposed of the Registrable Certificates or (B) for a period
 exceeding 90 days after the last Exchange Date (as such period may be
 extended pursuant to the penultimate paragraph of Section 3 of this
 Agreement) and Participating Broker-Dealers shall not be authorized by the
 Company to deliver and shall not deliver such Prospectus after such period in
 connection with the resales contemplated by this Section 4; and 

	
 

	
 

	
 

	
          (ii)
the application of the Shelf Registration procedures set forth in Section 3
of this Agreement to an Exchange Offer Registration, to the extent not
required by the positions of the Staff of the SEC or the 1933 Act and the
rules and regulations thereunder, will be in conformity with the reasonable
request to the Company by the Initial Purchasers or with the reasonable
request in writing to the Company by one or more broker-dealers who certify
to the Initial Purchasers and the Company in writing that they anticipate
that they will be Participating Broker-Dealers; and provided further that, in
connection with such application of the Shelf Registration procedures set
forth in Section 3 to an Exchange Offer Registration, the Company shall be
obligated (x) to deal only with one entity representing the Participating Broker-Dealers,
which shall be Merrill Lynch unless it elects not to act as such
representative, (y) to pay the fees and expenses of only one counsel
representing the Participating Broker-Dealers, which shall be counsel to the
Initial Purchasers unless such counsel elects not to so act and (z) to cause
to be delivered only one, if any, “cold comfort” letter with respect to the
Prospectus in the form existing on the last Exchange Date and with respect to
each subsequent amendment or supplement, if any, effected during the period
specified in clause (i) above.  

                    (c)
The Initial Purchasers shall have no liability to the Company or any Holder
with respect to any request that it may make pursuant to Section 4(b) above. 

                    5. Indemnification
and Contribution. 

                    (a)
The Company agrees to indemnify and hold harmless the Initial Purchasers, each
Holder and each Person, if any, who controls any Initial Purchaser or any
Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of
the 1934 Act, or is under common control with, or is controlled by, any Initial
Purchaser or any Holder, from and against all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred by the Initial Purchasers, any Holder or any such
controlling or affiliated Person in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement (or any
amendment thereto) pursuant to which Exchange Certificates or Registrable
Certificates were registered under the 1933 Act, including all documents
incorporated therein by reference, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not 

14

misleading, or
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Prospectus (as amended or supplemented if the Company shall
have furnished any amendments or supplements thereto), any Free Writing
Prospectus or any Issuer Information filed or required to be filed pursuant to
Rule 433(d) under the 1933 Act in each case, taken together with the
prospectus, or caused by any omission or alleged omission to state therein a
material fact necessary to make the statements therein in the light of the
circumstances under which they were made not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to the Initial Purchasers or any Holder furnished to the Company in
writing through Merrill Lynch or any selling Holder expressly for use therein.
In connection with any Underwritten Offering permitted by Section 3, the
Company will also indemnify the Underwriters, if any, and dealers participating
in the distribution, their officers and directors and each Person who controls
such Persons (within the meaning of the 1933 Act and the 1934 Act) to the same
extent as provided above with respect to the indemnification of the Holders, if
requested in connection with any Registration Statement. 

                    (b)
Each Holder agrees, severally and not
jointly, to indemnify and hold harmless the Company, the Initial Purchasers and
the other selling Holders, and each of their respective directors, officers who
sign the Registration Statement and each Person, if any, who controls the
Company, any Initial Purchaser and any other selling Holder within the meaning
of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same
extent as the foregoing indemnity from the Company to the Initial Purchasers
and the Holders, but only with reference to information relating to such Holder
furnished to the Company in writing by such Holder expressly for use in any
Registration Statement (or any amendment thereto), any Prospectus (or any
amendment or supplement thereto) or any Free Writing Prospectus. 

                    (c) In
case any proceeding (including any
governmental investigation) shall be instituted involving any Person in respect
of which indemnity may be sought pursuant to either paragraph (a) or paragraph
(b) above, such Person (the “indemnified party”) shall promptly notify the
Person against whom such indemnity may be sought (the “indemnifying party”) in
writing and the indemnifying party, upon request of the indemnified party,
shall retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and shall pay the reasonable fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (a) the fees and expenses
of more than one separate firm (in addition to any local counsel) for the
Initial Purchasers and all Persons, if any, who control any Initial Purchaser
within the meaning of either Section 15 of the 1933 Act or Section 20 of the
1934 Act, (b) the fees and expenses of more than one separate firm (in addition
to any local counsel) for the Company, its directors, its officers who sign the
Registration 

15

Statement and
each Person, if any, who controls the Company within the meaning of either such
Section and (c) the fees and expenses of more than one separate firm (in
addition to any local counsel) for all Holders and all Persons, if any, who control
any Holders within the meaning of either such Section, and that all such fees
and expenses shall be reimbursed as they are incurred. In such case involving
the Initial Purchasers and Persons who control the Initial Purchasers, such
firm shall be designated in writing by the Initial Purchasers. In such case
involving the Holders and such Persons who control Holders, such firm shall be
designated in writing by the Majority Holders. In all other cases, such firm
shall be designated by the Company. The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent but,
if settled with such consent or if there be a final judgment for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written
consent if (i) such settlement is entered into more than 30 days after receipt
by such indemnifying party of the aforesaid request and (ii) such indemnifying
party shall not have reimbursed the indemnified party for such fees and
expenses of counsel in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which such indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party,
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding. 

                    (d) If
the indemnification provided for in
paragraph (a) or paragraph (b) of this Section 5 is unavailable to an
indemnified party or insufficient in respect of any losses, claims, damages or
liabilities, then each indemnifying party under such paragraph, in lieu of indemnifying
such indemnified party thereunder, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages
or liabilities in such proportion as is appropriate to reflect the relative
fault of the indemnifying party or parties on the one hand and of the
indemnified party or parties on the other hand in connection with the
statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company and the Holders shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by the Holders and the
parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Holders’ respective
obligations to contribute pursuant to this Section 5(d) are several in
proportion to the respective principal amount of Registrable Certificates of
such Holder that were registered pursuant to a Registration Statement. 

                    (e)
The Company and each Holder agree that it
would not be just or equitable if contribution pursuant to this Section 5 were
determined by pro rata allocation or by any other method of allocation that
does not take account of the equitable considerations referred to in paragraph
(d) above. The amount paid or payable by an indemnified party as a result of
the 

16

losses,
claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 5, no Holder shall be required to indemnify or
contribute any amount in excess of the amount by which the total price at which
Registrable Certificates were sold by such Holder exceeds the amount of any
damages that such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. The remedies provided for in this
Section 5 are not exclusive and shall not limit any rights or remedies which
may otherwise be available to any indemnified party at law or in equity. 

                    The
indemnity and contribution provisions contained in this Section 5 shall remain
operative and in full force and effect regardless of (i) any termination of
this Agreement, (ii) any investigation made by or on behalf of the Initial
Purchasers, any Holder or any Person controlling any Initial Purchaser or any
Holder, or by or on behalf of the Company, its officers or directors or any
Person controlling the Company, (iii) acceptance of any of the Exchange
Certificates and (iv) any sale of Registrable Certificates pursuant to a Shelf
Registration Statement. 

                    6.
Miscellaneous. 

                    (a) No
Inconsistent Agreements. The Company has
not entered into, and on or after the date of this Agreement will not enter
into, any agreement which is inconsistent with the rights granted to the
Holders of Registrable Certificates in this Agreement or otherwise conflicts with
the provisions hereof. The rights granted to the Holders hereunder do not in
any way conflict with and are not inconsistent with the rights granted to the
holders of the Company’s other issued and outstanding securities under any such
agreements. 

                    (b)
Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless the Company has obtained the written consent of Holders of at least a
majority in aggregate principal amount of the outstanding Registrable
Certificates affected by such amendment, modification, supplement, waiver or
consent; provided, however, that no amendment, modification, supplement, waiver
or consent to any departure from the provisions of Section 5 hereof shall be
effective as against any Holder of Registrable Certificates unless consented to
in writing by such Holder. 

                    (c)
Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, registered first-class
mail, telecopier, or any courier guaranteeing overnight delivery (i) if to a
Holder, at the most current address given by such Holder to the Company by
means of a notice given in accordance with the provisions of this Section 6(c),
which address initially is, with respect to the Initial Purchasers, the address
set forth in the Purchase Agreement; and (ii) if to the Company, initially at
the Company’s address 

17

set forth in
the Purchase Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 6(c). 

                    All
such notices and communications shall be deemed to have been duly given: at the
time delivered by hand, if personally delivered; five business days after being
deposited in the mail, postage prepaid, if mailed; when receipt is
acknowledged, if telecopied; and on the next business day if timely delivered
to an air courier guaranteeing overnight delivery. 

                    Copies
of all such notices, demands, or other communications shall be concurrently
delivered by the Person giving the same to the Trustee, at the address specified
in the Pass Through Trust Agreements. 

                    (d)
Successors and Assigns. This Agreement shall
inure to the benefit of and be binding upon the successors, assigns and
transferees of each of the parties, including, without limitation and without
the need for an express assignment, subsequent Holders; provided that nothing
herein shall be deemed to permit any assignment, transfer or other disposition
of Registrable Certificates in violation of the terms of the Purchase
Agreement. If any transferee of any Holder shall acquire Registrable
Certificates, in any manner, whether by operation of law or otherwise, such
Registrable Certificates shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Certificates such Person
shall be conclusively deemed to have agreed to be bound by and to perform all
of the terms and provisions of this Agreement and such Person shall be entitled
to receive the benefits hereof. The Initial Purchasers (in their capacity as Initial
Purchasers) shall have no liability or obligation to the Company with respect
to any failure by a Holder to comply with, or any breach by any Holder of, any
of the obligations of such Holder under this Agreement.  

                    (e)
Purchases and Sales of Certificates. The
Company shall not, and shall use its best efforts to cause its affiliates (as
defined in Rule 405 under the 1933 Act) not to, purchase and then resell or
otherwise transfer any Certificates prior to the consummation of the Exchange
Offer or a Shelf Registration Statement being declared effective. 

                    (f)
Third Party Beneficiary. The Holders shall be third party beneficiaries to the
agreements made hereunder between the Company, on the one hand, and the Initial
Purchasers, on the other hand, and shall have the right to enforce such
agreements directly to the extent it deems such enforcement necessary or
advisable to protect its rights or the rights of Holders hereunder. 

                    (g)
Counterparts. This Agreement may be executed in any number of counterparts and
by the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement. 

                    (h)
Headings. The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning hereof. 

                    (i)
Governing Law. This Agreement shall be governed by the laws of the State of New
York. 

18

                    (j)
Severability. In the event that any one or more of the provisions contained
herein, or the application thereof in any circumstance, is held invalid,
illegal or unenforceable, the validity, legality and enforceability of any such
provision in every other respect and of the remaining provisions contained
herein shall not be affected or impaired thereby. 

                    (k)
Trustee. The Trustee shall take action as
may be reasonably requested by the Company in connection with the Company
satisfying its obligations arising under this Agreement.
