interest in and to the Purchase Agreement) together with all rights, powers, privileges, options
and other benefits of the Owner in respect of such provisions (subject to such reservation) with
respect to the Airframe or the Engines, including, without limitation, the right to make all

to the Purchase Agreement, to the terms and conditions of the Consent and Agreement and the Engine
Consent and Agreement;

          (3) All proceeds with respect to the requisition of title to or use of the Aircraft or any
Engine by any Government Entity or from the sale or other disposition of the Aircraft, the
Airframe, any Engine or other property described in any of these Granting Clauses by the Mortgagee
pursuant to the terms of this Trust Indenture, and all insurance proceeds with respect to the
Aircraft, the Airframe, any Engine or any part thereof, but excluding any insurance maintained by
the Owner and not required under Section 4.06;

          (4) All rents, revenues and other proceeds collected by the Mortgagee pursuant to clause

the Owner pursuant to any terms of this Trust Indenture held or required to be held by the
Mortgagee hereunder, including the Securities Account and all monies and securities deposited into
the Securities Account; and

          (5) All proceeds of the foregoing.

          PROVIDED, HOWEVER, that notwithstanding any of the foregoing provisions, so long as no Event
of Default shall have occurred and be continuing, (a) the Mortgagee shall not take or cause to be
taken any action contrary to the Owner’s right hereunder to quiet enjoyment of the Airframe and
Engines, and to possess, use, retain and control the Airframe and Engines and all revenues, income
and profits derived therefrom, and (b) the Owner shall have the right, to the exclusion of the
Mortgagee, with respect to the Purchase Agreement, to exercise in the Owner’s name all rights and
powers assigned hereunder under the Purchase Agreement (other than to amend, modify or waive any of
the warranties or indemnities contained therein and assigned hereunder, except in the exercise of
the Owner’s reasonable business judgment) and to retain any recovery or benefit resulting from the
enforcement of any warranty or indemnity under the Purchase Agreement; and provided further
that, notwithstanding the occurrence or continuation of an Event of Default, the Mortgagee
shall not enter into any amendment of the Purchase Agreement which would increase the obligations
of the Owner thereunder.

          TO HAVE AND TO HOLD all and singular the aforesaid property unto the Mortgagee, and its
successors and assigns, in trust for the equal and proportionate benefit and security of the Note
Holders, the Related Secured Parties and the Indenture Indemnitees, except as provided in Section
2.13 and Article III hereof, without any preference, distinction or priority of any one Equipment
Note over any other, or any Related 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 Trust Indenture.

          It is expressly agreed that anything herein contained to the contrary notwithstanding, the
Owner shall remain liable under the Indenture Agreements to perform all of the obligations assumed
by it thereunder, except to the extent prohibited or excluded from doing so pursuant to the terms
and provisions thereof, and the Mortgagee, the Note Holders, the Related Secured Parties and the
Indenture Indemnitees shall have no obligation or liability under the Indenture Agreements by
reason of or arising out of the assignment hereunder, nor shall the Mortgagee, the Note Holders,
the Related Secured Parties or the Indenture Indemnitees be required or obligated in any manner to
perform or fulfill any obligations of the Owner under or pursuant to the Indenture Agreements, or,
except as herein expressly provided, to make any payment, 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 amounts which may have been assigned to it or to which it may
be entitled at any time or times.

          The Owner does hereby constitute the Mortgagee the true and lawful attorney of the Owner,
irrevocably, granted for good and valuable consideration and coupled with an interest and with full
power of substitution, and with full power (in the name of the Owner or otherwise)

3

 

to ask for, require, demand, receive, compound and give acquittance for any and all monies and claims for
monies (in each case including insurance and requisition proceeds) due and to become due under or arising out of the Indenture Agreements, 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 the Mortgagee may deem to be necessary or advisable in the premises;
provided that the Mortgagee shall not exercise any such rights except upon the occurrence
and during the continuance of an Event of Default hereunder.

          The Owner agrees that at any time and from time to time, upon the written request of the
Mortgagee, the Owner will promptly and duly execute and deliver or cause to be duly executed and
delivered any and all such further instruments and documents (including without limitation UCC
continuation statements) as the Mortgagee 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 the Mortgagee the full benefits of the assignment hereunder and of the rights and
powers herein granted.

          SOUTHWEST AIRLINES CO., a Texas corporation (“Owner”), hereby promises to pay to Wilmington
Trust Company, as Subordination Agent under the Intercreditor Agreement, or the registered assignee
thereof, the principal sum of $                     (the “Original Amount”), together with interest on the
amount of the Original Amount remaining unpaid from time to time (calculated on the basis of a year
of 360 days comprised of twelve 30-day months) from the date hereof until paid in full at a rate
per annum equal to the Debt Rate. The Original Amount of this Equipment Note shall be due and
payable in installments on the dates set forth in Schedule I hereto equal to the corresponding
percentage of the Original Amount of this Equipment Note set forth in Schedule I hereto. Accrued
but unpaid interest shall be due and payable in arrears in semi-annual installments commencing on
February 1, 2008, and thereafter on February 1 and August 1 of each year, to and including
[                                        ]. Notwithstanding the foregoing, the final payment made on this Equipment Note
shall be in an amount sufficient to discharge in full the unpaid Original Amount and all accrued
and unpaid interest on, and any other amounts due under, this Equipment Note. Notwithstanding
anything to the contrary contained herein, if any date on which a payment under this Equipment Note
becomes due and payable is not a Business Day, then such payment shall not be made on such
scheduled date but shall be made on the next succeeding Business Day and if such payment is made on
such next succeeding Business Day, no interest shall accrue on the amount of such payment during
such extension.

          For purposes hereof, the term “Trust Indenture” means the Trust Indenture and Mortgage N259WN
dated as of October 3, 2007, between the Owner and Wilmington Trust Company (the “Mortgagee”), as
the same may be amended or supplemented from time to time. All other capitalized terms used in
this Equipment Note and not defined herein shall have the respective meanings assigned in the Trust
Indenture.

          This Equipment Note shall bear interest, payable on demand, at the Payment Due Rate
(calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any overdue
Original Amount, any overdue Make-Whole Amount, if any, and (to the extent permitted by applicable
Law) any overdue interest and any other amounts payable hereunder which are overdue, in each case
for the period the same is overdue. Amounts shall be overdue if not paid when due (whether at
stated maturity, by acceleration or otherwise).

          There shall be maintained an Equipment Note Register for the purpose of registering transfers
and exchanges of Equipment Notes at the Corporate Trust Office of the Mortgagee or at the office of
any successor in the manner provided in Section 2.07 of the Trust Indenture.

          The Original Amount and interest and other amounts due hereunder shall be payable in Dollars
in immediately available funds at the Corporate Trust Office of the

5

 

Mortgagee, or as otherwise provided in the Trust Indenture. Each such payment shall be made on the date such payment is due
and without any presentment or surrender of this Equipment Note, except that in the case of any final payment with respect to this Equipment Note, the
Equipment Note shall be surrendered promptly thereafter to the Mortgagee for cancellation.

          The holder hereof, by its acceptance of this Equipment Note, agrees that, except as provided
in the Trust Indenture, each payment of the Original Amount, Make-Whole Amount, if any, and
interest received by it hereunder shall be applied, first, to the payment of accrued
interest on this Equipment Note (as well as any interest on any overdue Original Amount, any
overdue Make-Whole Amount, if any, or, to the extent permitted by Law, any overdue interest and
other amounts hereunder) to the date of such payment, second, to the payment of the
Original Amount of this Equipment Note then due, third, to the payment of Make-Whole
Amount, if any, and any other amount due hereunder or under the Trust Indenture, and
fourth, the balance, if any, remaining thereafter, to the payment of installments of the
Original Amount of this Equipment Note remaining unpaid in the inverse order of their maturity.

          This Equipment Note is one of the Equipment Notes referred to in the Trust Indenture which
have been or are to be issued by the Owner pursuant to the terms of the Trust Indenture. The
Collateral is held by the Mortgagee as security, in part, for the Equipment Notes. The provisions
of this Equipment Note are subject to the Trust Indenture and each Related Indenture as set forth
therein. Reference is hereby made to the Trust Indenture and the Related Indentures for a complete
statement of the rights and obligations of the holder of, and the nature and extent of the security
for, this Equipment Note (including as a “Related Equipment Note” under each of the Related
Indentures) and the rights and obligations of the holders of, and the nature and extent of the
security for, any other Equipment Notes executed and delivered under the Trust Indenture, as well
as for a statement of the terms and conditions of the Trust created by the Trust Indenture and each
Related Indenture, to all of which terms and conditions in the Trust Indenture and each Related
Indenture each holder hereof agrees by its acceptance of this Equipment Note.

          As provided in the Trust Indenture and subject to certain limitations therein set forth, this
Equipment Note is exchangeable for a like aggregate Original Amount of Equipment Notes of different
authorized denominations, as requested by the holder surrendering the same.

          Prior to due presentment for registration of transfer of this Equipment Note, the Owner and
the Mortgagee shall treat the person in whose name this Equipment Note is registered as the owner
hereof for all purposes, whether or not this Equipment Note be overdue, and neither the Owner nor
the Mortgagee shall be affected by notice to the contrary.

          This Equipment Note is subject to redemption as provided in Sections 2.10, 2.11 and 2.12 of
the Trust Indenture but not otherwise. In addition, this Equipment Note may be accelerated as
provided in Section 5.02 of the Trust Indenture.

          This Equipment Note is subject to purchase as set forth in Section 2.7 of the Intercreditor
Agreement, and to certain restrictions set forth in Sections 4.1(a)(ii) and 4.1(a)(iii) of the
Intercreditor Agreement, as further specified in Section 2.07 of the Trust Indenture, to all of
which terms and conditions in the Intercreditor Agreement each holder hereof agrees by its
acceptance of this Equipment Note.

          SECTION 2.02. Issuance and Terms of Equipment Notes

          The Equipment Notes (other than the Additional Series Equipment Notes) shall be dated the
Closing Date, shall be issued in two separate series consisting of Series A and Series B and in the
maturities and principal amounts and shall bear interest as specified in Schedule I hereto. On the
Closing Date, each Series of Equipment Note (other than the Additional Series Equipment Notes)
shall be issued to the Subordination Agent on behalf of the Applicable Pass Through Trustee under
the Applicable Pass Through Trust Agreement. In addition to the foregoing, Owner shall have the
option to issue Additional Series Equipment Notes at any time and from time to time after the
Closing Date; provided, that the Owner shall not issue any such Additional Series unless it shall
have obtained Ratings Confirmation from each Rating Agency. 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 C” and “Series D”), 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 Trust 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 or Additional Series Equipment
Notes may be issued in accordance with the terms of this Trust Indenture.

          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) on the unpaid Original Amount thereof from time to time
outstanding. Accrued interest shall be payable in arrears on February 1, 2008, and on each
February 1 and August 1 thereafter until maturity. The Original Amount of each Equipment Note
shall be payable on the dates and in the installments equal to the corresponding percentage of the
Original Amount as set forth in Schedule I hereto (as amended, in the case of any Additional
Series, at the time of original issuance of such Additional Series) which shall be attached as
Schedule I to such Equipment Notes. Notwithstanding the foregoing, the final payment made under
each Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original
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 Payment Due Rate
(calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any part of
the Original Amount, Make-Whole Amount, if any, 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 shall be overdue, in each case for the period the same is overdue. Amounts under any
Equipment Note shall be overdue if not paid when due (whether at stated maturity, by acceleration
or otherwise). Notwithstanding anything to the contrary contained herein, whenever the date
scheduled for any payment to be made hereunder or under any Equipment Note shall not be a Business
Day, then such payment shall not be due on such scheduled date but shall be due on the next
succeeding Business Day and if such payment is made on such next succeeding Business Day, no
interest shall accrue on the amount of such payment during such extension.

10

 

          The Owner agrees to pay to the Mortgagee for distribution in accordance with Section 3.04
hereof: (i) an amount equal to the fees payable to the Liquidity Provider under Section 2.03 of the Liquidity Facility and the related Fee Letter (as defined in the
Intercreditor Agreement) multiplied by a fraction the numerator of which shall be the then
outstanding aggregate principal amount of the Series A Equipment Notes and the denominator of which
shall be the then outstanding aggregate principal amount of all “Series A Equipment Notes” (each as
defined in the Intercreditor Agreement); (ii) (x) the amount equal to interest on any Downgrade
Advance (other than any Applied Downgrade Advance) payable under Section 3.07 of the Liquidity
Facility minus Investment Earnings from such Downgrade Advance multiplied by (y) the fraction
specified in the foregoing clause (i); (iii) (x) the amount equal to interest on any Non-Extension
Advance (other than any Applied Non-Extension Advance) payable under Section 3.07 of the Liquidity
Facility minus Investment Earnings from such Non-Extension Advance multiplied by (y) the fraction
specified in the foregoing clause (i); (iv) the amount equal to interest on any Special Termination
Advance (other than any Applied Special Termination Advance) payable under Section 3.07 of each
Liquidity Facility minus Investment Earnings from such Special Termination Advance multiplied by
the fraction specified in the foregoing clause (i); (v) if any payment default shall have occurred
and be continuing with respect to interest on any “Series A Equipment Notes” (as defined in the
Intercreditor Agreement), (x) the excess, if any, of (1) an amount equal to interest on any Unpaid
Advance, Applied Downgrade Advance or Applied Non-Extension Advance payable under Section 3.07 of
the Liquidity Facility over (2) the sum of Investment Earnings from any Final Advance plus any
amount of interest at the Payment Due Rate actually payable (whether or not in fact paid) by Owner
on the overdue scheduled interest on the “Equipment Notes” (as defined in the Intercreditor
Agreement) in respect of which such Unpaid Advance, Applied Downgrade Advance or Applied
Non-Extension Advance was made by the Liquidity Provider multiplied by (y) a fraction the numerator
of which shall be the then aggregate overdue amounts of interest on the Series A Equipment Notes
(other than interest becoming due and payable solely as a result of acceleration of any such
Equipment Notes) and the denominator of which shall be the then aggregate overdue amounts of
interest on all “Series A Equipment Notes” (other than interest becoming due and payable solely as
a result of acceleration of any such “Equipment Notes”); (vi) any other amounts owed to the
Liquidity Provider by the Subordination Agent as borrower under the Liquidity Facility multiplied
by the fraction specified in the foregoing clause (i) other than (A) amounts due as repayment of
advances thereunder or as interest on such advances, except to the extent payable pursuant to
clause (ii), (iii), (iv) or (v) above and (B) fees payable under Section 2.03 of the Liquidity
Facility; (vii) Owner’s pro rata share of all compensation and reimbursement of expenses,
disbursements and advances payable by Owner under the Pass Through Trust Agreements; and (viii)
Owner’s pro rata share of all compensation and reimbursement of expenses and disbursements payable
to the Subordination Agent under the Intercreditor Agreement except with respect to any
Unindemnified Taxes incurred by the Subordination Agent in connection with the transactions
contemplated by the Intercreditor Agreement. As used herein, “Owner’s pro rata share” means as of
any
 time a fraction, the numerator of which is the principal balance then outstanding of Equipment
Notes and the denominator of which is the aggregate principal balance then outstanding of all
“Equipment Notes” (as such term is defined in each of the Operative Indentures). For purposes of
this paragraph, the terms “Applied Downgrade Advance”, “Applied Non-Extension Advance”, “Applied
Special Termination Advance”, “Downgrade Advance”, “Final Advance”, “Investment Earnings”,
“Non-Extension Advance”, “Special Termination Advance” and “Unpaid Advance”

11

 

shall have the meanings specified in the Liquidity Facility or the Intercreditor Agreement, as applicable.

          The Equipment Notes shall be executed on behalf of the Owner by one of its authorized
officers. Equipment Notes bearing the signatures of individuals who were at any time the proper
officers of the Owner shall bind the Owner, 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. The Owner may from
time to time execute and deliver Equipment Notes with respect to the Aircraft to the Mortgagee for
authentication upon original issue and such Equipment Notes shall thereupon be authenticated and
delivered by the Mortgagee upon the written request of the Owner signed by an authorized officer of
the Owner. No Equipment Note shall be secured by or entitled to any benefit under this Trust
Indenture or be valid or obligatory for any purposes, unless there appears on such Equipment Note a
certificate of authentication in the form provided for herein executed by the Mortgagee by the
manual signature of one of its authorized officers and such certificate upon any Equipment Notes be
conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated
and delivered hereunder.

          SECTION 2.03. [Intentionally Omitted]

          SECTION 2.04. Method of Payment

               (a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due
under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately
available funds not later than 12:30 PM, New York time, on the due date of payment to the Mortgagee
at the Corporate Trust Office for distribution among the Note Holders in the manner provided
herein, and payment of such amount to the Mortgagee shall be deemed to satisfy the Owner’s
obligation to make such payment. The Owner shall not have any responsibility for the distribution
of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any
Equipment Note to the contrary, the Mortgagee will use reasonable efforts to pay or cause to be
paid, if so directed in writing by any Note Holder (with a copy to the Owner), all amounts paid by
the Owner hereunder and under such holder’s Equipment Note or Equipment Notes to such holder or a
nominee therefor (including all amounts distributed pursuant to Article III of this Trust
Indenture) by transferring, or causing to be transferred, by wire transfer of immediately available
funds in Dollars, prior to 2:00 p.m., New York City time, on the due date of payment, to an account
maintained by such holder with a bank located in the continental United States the amount to be
distributed to such holder, for credit to the account of such holder maintained at such bank. If
the Mortgagee shall fail to make any such payment as provided in the immediately foregoing sentence
after its receipt of funds at the place and prior to the time specified above, the Mortgagee, in
its individual capacity and not as trustee, agrees to compensate such holders for loss of use of
funds at Debt Rate until such payment is made and the Mortgagee 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 the Mortgagee for
cancellation promptly after such payment. Notwithstanding any other provision of this Trust
Indenture to the contrary, the Mortgagee shall not be required to make, or cause to be made, wire
transfers as aforesaid prior to

12

 

the first Business Day on which it is practicable for the Mortgagee 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 12:30 PM, New York time, at the place of payment. Prior to the due
presentment for registration of transfer of any Equipment Note, the Owner and the Mortgagee shall deem and treat the Person
in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner
and holder 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 none of the Owner or the Mortgagee
shall be affected by any notice to the contrary. So long as any signatory to the Participation
Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to
the account of such Note Holder specified in Schedule 1 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 the Mortgagee consistent with this Section 2.04.

               (b) The Mortgagee, as agent for the Owner, shall exclude and withhold at the appropriate rate
from each payment of Original Amount of, interest on, Make-Whole Amount, if any, and other amounts
due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute
payment in respect of such Equipment Note) any and all United States withholding taxes applicable
thereto as required by Law. The Mortgagee agrees to act as such withholding agent and, in
connection therewith, whenever any present or future United States 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 and timely pay the same to the appropriate authority in
the name of and on behalf of the Note Holders, that it will file any necessary United States
withholding tax returns or statements when due, and that as promptly as possible after the payment
thereof it will deliver to each Note Holder (with a copy to the Owner) appropriate receipts showing
the payment thereof, together with such additional documentary evidence as any such Note Holder may
reasonably request from time to time.

          If a Note Holder which is a Non-U.S. Person has furnished to the Mortgagee a properly
completed and accurate U.S. Internal Revenue Service Form W-8BEN, W-8EXP, W-8IMY or W-8ECI (or such
successor form or forms as may be required by the United States Treasury Department) that is
effective at the time a payment hereunder or under the Equipment Note(s) held by such holder is
made and has not notified the Mortgagee of the withdrawal or inaccuracy of such form prior to the
date of such payment (and the Mortgagee has no reason to believe that any information set forth in
such form is inaccurate), the Mortgagee shall withhold only the amount, if any, required by Law
(after taking into account any applicable exemptions properly claimed by the Note Holder) to be
withheld from payments hereunder or under the Equipment Notes held by such holder in respect of
United States federal income tax. If a Note Holder (x) which is a Non-U.S. Person has furnished to
the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service
Form W-8ECI in duplicate (or such successor certificate, form or forms as may be required by the
United States Treasury Department as necessary in order to properly avoid withholding of United
States federal income tax), for each calendar year in which a payment is made (but prior to the
making of any payment for such year), and has not notified the Mortgagee of the withdrawal or
inaccuracy of such certificate or form prior to the date of such payment (and the Mortgagee has no
reason to believe that any information set forth in such form is inaccurate) or (y) which is a U.S.
Person has

13

 

furnished to the Mortgagee a properly completed, accurate and currently effective U.S.
Internal Revenue Service Form W-9, if applicable, prior to a payment hereunder or under the
Equipment Notes held by such holder, no amount shall be withheld from payments in respect of United States federal income tax. If any Note Holder has notified the Mortgagee that any of the
foregoing forms or certificates is withdrawn or inaccurate, or if such holder has not filed a form
claiming an exemption from United States withholding tax or if the Code or the regulations
thereunder or the administrative interpretation thereof is at any time after the date hereof
amended to require such withholding of United States federal income taxes from payments under the
Equipment Notes held by such holder, the Mortgagee agrees to withhold from each payment due to the
relevant Note Holder United States federal withholding taxes at the appropriate rate under Law and
will, on a timely basis as more fully provided above, deposit such amounts with an authorized
depository and make such returns, statements, receipts and other documentary evidence in connection
therewith as required by Law.

          Owner shall not have any liability for the failure of the Mortgagee to withhold taxes in the
manner provided for herein or for any false, inaccurate or untrue evidence provided by any Note
Holder hereunder.

          SECTION 2.05. Application of Payments

          In the case of each Equipment Note, each payment of Original Amount, Make-Whole Amount, if
any, and interest due thereon shall be applied:

     First: to the payment of Make-Whole Amount, if any, with respect to such Equipment
Note and any other amount (other than as covered by any of the following clauses) due
hereunder with respect to such Equipment Note or under such Equipment Note;

     Second: to the payment of accrued interest on such Equipment Note (as well as any
interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, and to the
extent permitted by Law, any overdue interest and any other overdue amounts thereunder) to
the date of such payment;

     Third: to the payment of the Original Amount of such Equipment Note (or a portion
thereof) then due thereunder; and

     Fourth: the balance, if any, remaining thereafter, to the payment of the Original
Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not
be subject to redemption except as provided in Sections 2.10, 2.11 and 2.12 hereof).

The amounts paid pursuant to clause “Fourth” above shall be applied to the installments of Original
Amount of such Equipment Note in the inverse order of their scheduled maturity.

14

 

          SECTION 2.06. Termination of Interest in Collateral

          No Note Holder or any other Indenture Indemnitee shall, as such, have any further interest in,
or other right with respect to, the Collateral when and if all of the Secured Obligations shall
have been paid in full.

          No Related Secured Party shall have any further interest in, or other right with respect to,
the Collateral when and if all Related Secured Obligations shall have been paid in full.

          SECTION 2.07. Registration Transfer and Exchange of Equipment Notes

          The Mortgagee shall keep a register (the “Equipment Note Register”) in which the Mortgagee
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
the Mortgagee. The Mortgagee 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 such Equipment Note shall surrender such Equipment Note to the
Mortgagee at the Corporate Trust Office, together with a written request from the registered holder
thereof for the issuance of a new Equipment Note, 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, the Owner shall execute, and the Mortgagee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more new Equipment Notes
of a like aggregate Original Amount and of the same Series. At the option of the Note Holder,
Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a
like aggregate Original Amount and of the same Series, upon surrender of the Equipment Notes to be
exchanged to the Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so
surrendered for exchange, the Owner shall execute, and the Mortgagee shall authenticate and
deliver, the Equipment Notes which the Note Holder 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 hereof or otherwise under this Trust Indenture) shall
be the valid obligations of the Owner evidencing the same respective obligations, and entitled to
the same security and benefits under this Trust 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 the Mortgagee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the Mortgagee duly executed
by the Note Holder or such holder’s attorney duly authorized in writing, and the Mortgagee 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. The Mortgagee shall make a notation on each
new Equipment Note of the amount of all payments of Original 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. Interest shall
be deemed to have been paid on such new Equipment Note to the date on which interest shall have
been paid on such old Equipment Note, and all payments of the Original Amount marked on such new
Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner shall not
be

15

 

required to exchange any surrendered Equipment Notes as provided above during the ten-day period
preceding the due date of any scheduled payment on such Equipment Note. The Owner shall in all
cases deem the Person in whose name any Equipment Note shall have been issued and registered as the
absolute owner and holder of such Equipment Note for the purpose of receiving payment of all
amounts payable by the Owner with respect to such Equipment Note and for all purposes until a
notice stating otherwise is received from the Mortgagee and such change is reflected on the Equipment Note Register. The Mortgagee will promptly notify the
Owner of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment
Note, by its acceptance of an Equipment Note, (i) agrees to the provisions of this Trust Indenture
and the Participation Agreement applicable to Note Holders, including Sections 6.3, 6.4 and 9.1
thereof, and shall be deemed to have covenanted to the parties to the Participation Agreement as to
the matters covenanted by the original Note Holder in the Participation Agreement, (ii) agrees to
the restrictions set forth in Sections 4.1(a)(ii) and 4.1(a)(iii) of the Intercreditor Agreement,
and shall be deemed to have covenanted to the parties to the Intercreditor Agreement not to give
any direction, or otherwise authorize, the Mortgagee to take any action that would violate Sections
4.1(a)(ii) or 4.1(a)(iii) of the Intercreditor Agreement, and (iii) agrees to the provisions of
Section 2.7 of the Intercreditor Agreement, and shall be deemed to have covenanted to the parties
to the Intercreditor Agreement to perform its obligations as a Note Holder under Section 2.7 of the
Intercreditor Agreement. Subject to compliance by the Note Holder and its transferee (if any) of
the requirements set forth in this Section 2.07, Mortgagee and Owner shall use all reasonable
efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date
an Equipment Note is surrendered for transfer or exchange.

          SECTION 2.08. Mutilated, Destroyed, Lost or Stolen Equipment Notes

          If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner shall, upon
the written request of the holder of such Equipment Note, execute and the Mortgagee shall
authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original
Amount dated the same date and captioned as issued in connection with the Aircraft. If the
Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the
Mortgagee and a photocopy thereof shall be furnished to the Owner. If the Equipment Note being
replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the
Owner and the Mortgagee such security or indemnity as may be required by them to save and hold the
Owner and the Mortgagee harmless and evidence satisfactory to the Owner and the Mortgagee of the
destruction, loss or theft of such Equipment Note and of the ownership thereof. If a “qualified
institutional buyer” of the type referred to in paragraph (a)(1)(i)(A), (B), (D) or (E) of Rule
144A under the Securities Act (a “QIB”) is the holder of any such destroyed, lost or stolen
Equipment Note, then the written indemnity of such QIB, signed by an authorized officer thereof, in
favor of, delivered to and in form reasonably satisfactory Owner shall be accepted as satisfactory
indemnity and security and no further indemnity or security shall be required as a condition to the
execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder with
the requirements set forth in this Section 2.08, Mortgagee and Owner shall use all reasonable
efforts to issue new Equipment Notes within 10 Business Days of the date of the written request
therefor from the Note Holder.

16

 

          SECTION 2.09. Payment of Expenses on Transfer; Cancellation

               (a) No service charge shall be made to a Note Holder for any registration of transfer or
exchange of Equipment Notes, but the Mortgagee, as Equipment Note Registrar, may require payment of
a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of
Equipment Notes.

               (b) The Mortgagee shall cancel all Equipment Notes surrendered for replacement, redemption,
transfer, exchange, payment or cancellation and shall destroy the canceled Equipment Notes.

          SECTION 2.10. Mandatory Redemptions of Equipment Notes

               On the date on which the Owner is required pursuant to Section 4.05 hereof to make payment for
an Event of Loss with respect to the Airframe, all of the Equipment Notes shall be redeemed in
whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with all
accrued interest thereon to the date of redemption and all other Secured Obligations owed or then
due and payable to the Note Holders but without Make-Whole Amount.

          SECTION 2.11. Voluntary Redemptions of Equipment Notes

               (a) All (but not less than all) of the Equipment Notes may be redeemed by the Owner upon at
least 20 days’ revocable prior written notice to the Note Holders given pursuant to Section
2.12(b), and such Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of
the unpaid Original Amount thereof, together with accrued interest thereon to the date of
redemption and all other Secured Obligations owed or then due and payable to the Note Holders plus
Make-Whole Amount, if any.

               (b) All (but not less than all) of the Equipment Notes of any of the Series B or of any
particular Series of Additional Series Equipment Notes may be redeemed by the Owner upon at least
20 days’ revocable prior written notice to the Note Holders of each Series to be redeemed given
pursuant to Section 2.12(b), and such Equipment Notes shall be redeemed in whole at a redemption
price equal to 100% of the unpaid Original Amount thereof, together with accrued interest thereon
to the date of redemption and all other Secured Obligations owed or then due and payable to the
Note Holders of such Series plus Make-Whole Amount, if any; provided that no redemption
shall be permitted under this Section 2.11(b) unless the following conditions have been satisfied:
(1) simultaneously with such redemption, the Related Series B Equipment Notes (in the case of
redemption hereunder of the Series B Equipment Notes) or the Related Additional Series Equipment
Notes in respect of the Additional Series Equipment Notes being redeemed (in the case of redemption
of any series of Additional Series Equipment Notes), as the case may be, shall also be redeemed;
and (2) simultaneously with such redemption, new Series B Equipment Notes (in the case of
redemption hereunder of the Series B Equipment Notes) or Additional Series Equipment Notes of the
same Series being redeemed (in the case of redemption hereunder of a series of Additional Series
Equipment Notes) shall be reissued in accordance with the terms of this Trust Indenture and Section
9.1(c) of the Intercreditor Agreement.

17

 

               (c) Notwithstanding Section 2.11(b), all (but not less than all) of the Series B Equipment Notes may be redeemed
by the Owner upon at least 20 days’ revocable prior written notice to the Note Holders of Series B given pursuant
to Section 2.12(b) at a redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued
interest thereon to the date of redemption and all other Secured Obligations owed or then due and payable to the Note
Holders of the Series B Equipment Notes, plus Make-Whole Amount, if any; provided that no such redemption shall
be permitted unless (x) simultaneously with such redemption, the Related Series B Equipment Notes shall also be
redeemed in accordance with the terms of the Related Indentures and (y) the Rating Agencies shall have provided
Ratings Confirmation with respect to any Certificates that will remain outstanding after such redemption, if such Certificates
are then rated by the Rating Agencies.

          SECTION 2.12. Redemptions; Notice of Redemption

               (a) No redemption of any Equipment Note may be made except to the extent and in the manner
expressly permitted by this Trust Indenture. No purchase of any Equipment Note may be made by the
Mortgagee.

               (b) Notice of redemption with respect to the Equipment Notes shall be given by the Mortgagee
by first-class mail, postage prepaid, mailed not less than 20 nor more than 60 days prior to the
applicable redemption date, to each Note Holder of such Equipment Notes to be redeemed, at such
Note Holder’s address appearing in the Equipment Note Register; provided that such notice shall be
revocable by written notice from the Owner to Mortgagee given not later than three days prior to
the redemption date. All notices of redemption shall state: (1) the redemption date, (2) the
applicable basis for determining the redemption price, (3) that on the redemption date, the
redemption price will become due and payable upon each such Equipment Note, and that, if any such
Equipment Notes are then outstanding, interest on such Equipment Notes shall cease to accrue on and
after such redemption date, and (4) the place or places where such Equipment Notes are to be
surrendered for payment of the redemption price. At least 10 days (unless a shorter time shall be
agreeable to Mortgagee) in advance of the date such notice of redemption is to be given by

notwithstanding anything to the contrary in this Trust Indenture, (i) any amounts to be held by the
Mortgagee pursuant to clause “Fifth” of Section 3.03 and any investment earnings thereon or other
Cash Equivalents 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 the Mortgagee 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, Cash Equivalents and all other property acquired with cash credited to the
Securities Account will be credited to the Securities Account, (iii) all items of property (whether

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 entitlement” to the “financial assets” credited to the Securities Account in trust for
the benefit of the Note Holders and each of the Indenture Indemnitees and the Related Secured
Parties as set forth in this Trust Indenture. The Owner acknowledges that, by reason of the
Mortgagee being the “entitlement holder” in respect of the Securities Account as provided above,
the Mortgagee shall have the sole right and discretion, subject only to the terms of this Trust
Indenture, to give all “entitlement orders” (as defined in Section 8-102(a)(8) of the NY UCC) with

Engines will be recognized in such jurisdiction, (y) the Laws of such jurisdiction of domicile
require fair compensation by the government of such jurisdiction, payable in a currency freely
convertible into Dollars, for the loss of title to the Aircraft, Airframe or Engines in the event
of the requisition by such government of such title (unless Owner shall provide insurance in the
amounts required with respect to hull insurance under this Trust Indenture covering the requisition
of title to the Aircraft, Airframe or Engines by the government of such jurisdiction so long as the
Aircraft, Airframe or Engines are subject to such lease) and (z) the agreement of such Permitted
Air Carrier that its rights under the lease are subject and subordinate to all the terms of this
Trust Indenture is enforceable against such Permitted Air Carrier under applicable law (subject to
customary exceptions);

provided that (1) the rights of any transferee who receives possession by reason of a
transfer permitted by any of clauses (i) through (viii) of this Section 4.02(b) (other than by a
transfer of an Engine which is deemed an Event of Loss) shall be subject and subordinate to all the
terms of this Trust Indenture, (2) the Owner shall remain primarily liable for the performance of
all of the terms of this Trust Indenture and all the terms and conditions of this Trust Indenture
and the other Operative Agreements shall remain in effect and (3) no lease or transfer of
possession otherwise in compliance with this Section 4.02(b) shall (x) result in any registration
or re-registration of an Aircraft, except to the extent permitted by Section 4.02(e) or the
maintenance,

28

 

operation or use thereof except in compliance with Sections 4.02(c) and 4.02(d) or (y) permit any
action not permitted to the Owner hereunder.

          In the case of any lease permitted under this Section 4.02(b), the Owner will include in such
lease appropriate provisions which (t) make such lease expressly subject and subordinate to all of
the terms of this Trust Indenture, including the rights of the Mortgagee to avoid such lease in the
exercise of its rights to repossession of the Airframe and Engines hereunder; (u) require the
Permitted Lessee to comply with the terms of Section 4.06; and (v) require that the Airframe or any
Engine subject thereto be used in accordance with the limitations applicable to the Owner’s
possession and use provided in this Trust Indenture. No lease permitted under this Section 4.02(b)
shall be entered into unless (w) Owner shall provide written notice to Mortgagee (such notice in
the event of a lease to a U.S. Air Carrier to be given promptly after entering into any such lease
or, in the case of a lease to any other Permitted Air Carrier, 10 days in advance of entering into
such lease); (x) Owner shall furnish to Mortgagee evidence reasonably satisfactory to Mortgagee
that the insurance required by Section 4.06 remains in effect; (y) all necessary documents shall
have been duly filed, registered or recorded in such public offices as may be required fully to
preserve the first priority security interest and International Interest (subject to Permitted
Liens) of Mortgagee in the Aircraft, Airframe and Engines; and (z) Owner shall reimburse Mortgagee
for all of its reasonable out-of-pocket fees and expenses, including, without limitation,
reasonable fees and disbursements of counsel, incurred by Mortgagee in connection with any such
lease. Except as otherwise provided herein and without in any way relieving the Owner from its
primary obligation for the performance of its obligations under this Trust Indenture, the Owner may
in its sole discretion permit a lessee to exercise any or all rights which the Owner would be
entitled to exercise under Sections 4.02 and 4.04, and may cause a lessee to perform any or all of
the Owner’s obligations under Article IV, and the Mortgagee agrees to accept actual and full
performance thereof by a lessee in lieu of performance by the Owner.

          Mortgagee hereby agrees, and each Note Holder and Related Note Holder by acceptance of an
Equipment Note and a Related Equipment Note, respectively, agrees, for the benefit of each lessor,
conditional seller, indenture trustee or secured party of any engine leased to, or purchased by,
Owner or any Permitted Lessee subject to a lease, conditional sale, trust indenture or other
security agreement that Mortgagee, each Note Holder and Related Note Holder and their respective
successors and assigns will not acquire or claim, as against such lessor, conditional seller,
indenture trustee or secured party, any right, title or interest in any engine as the result of
such engine being installed on the Airframe at any time while such engine is subject to such lease,
conditional sale, trust indenture or other security agreement and owned by such lessor or
conditional seller or subject to a trust indenture or security interest in favor of such indenture
trustee or secured party.

               (c) Operation and Use. So long as the Aircraft, Airframe or any Engine is subject to
the Lien of this Trust Indenture, the Owner shall not operate, use or locate the Aircraft, Airframe
or any Engine, or allow the Aircraft, Airframe or any Engine to be operated, used or located, (i)
in any area excluded from coverage by any insurance required by the terms of Section 4.06, except
in the case of a requisition by the U.S. Government where the Owner obtains indemnity in lieu of
such insurance from the U.S. Government, or insurance from the U.S. Government, against
substantially the same risks and for at least the amounts of the

29

 

insurance required by Section 4.06 covering such area, or (ii) in any recognized area of
hostilities unless covered in accordance with Section 4.06 by war risk insurance, or in either case
unless the Aircraft, the Airframe or any Engine is only temporarily operated, used or located in
such area as a result of an emergency, equipment malfunction, navigational error, hijacking,
weather condition or other similar unforeseen circumstance, so long as Owner diligently and in good
faith proceeds to remove the Aircraft from such area. So long as the Aircraft, the Airframe or any
Engine is subject to the Lien of this Trust Indenture, the Owner shall not permit such Aircraft,
Airframe or any Engine, as the case may be, to be used, operated, maintained, serviced, repaired or
overhauled (x) in violation of any Law binding on or applicable to such Aircraft, Airframe or
Engine or (y) in violation of any airworthiness certificate, license or registration of any
Government Entity relating to the Aircraft, the Airframe or any Engine, except (i) immaterial or
non-recurring violations with respect to which corrective measures are taken promptly by Owner or
Permitted Lessee, as the case may be, upon discovery thereof, or (ii) to the extent the validity or
application of any such Law or requirement relating to any such certificate, license or
registration is being contested in good faith by Owner or Permitted Lessee in any reasonable manner
which does not involve any material risk of the sale, forfeiture or loss of the Aircraft, Airframe
or any Engine, any material risk of criminal liability or material civil penalty against Mortgagee
or impair the Mortgagee’s security interest in the Aircraft, Airframe or any Engine.

               
(d) Maintenance and Repair. So long as the Aircraft, Airframe or any Engine is
subject to the Lien of this Trust Indenture, the Owner shall cause the Aircraft, Airframe and each
Engine to be maintained, serviced, repaired and overhauled in accordance with (i) maintenance
standards required by or substantially equivalent to those required by the FAA or the central
aviation authority of Canada, France, Germany, Japan, the Netherlands or the United Kingdom for the
Aircraft, Airframe and Engines, so as to (A) keep the Aircraft, the Airframe and each Engine in as
good operating condition as on the Closing Date, ordinary wear and tear excepted, (B) keep the
Aircraft in such operating condition as may be necessary to enable the applicable airworthiness
certification of such Aircraft to be maintained under the regulations of the FAA or other Aviation
Authority then having jurisdiction over the operation of the Aircraft, except during (x) temporary
periods of storage in accordance with applicable regulations, (y) maintenance and modification
permitted hereunder or (z) periods when the FAA or such other Aviation Authority has revoked or
suspended the airworthiness certificates for Similar Aircraft; and (ii) except during periods when
a Permitted Lease is in effect, the same standards as Owner uses with respect to similar aircraft
of similar size in its fleet operated by Owner in similar circumstances and, during any period in
which a Permitted Lease is in effect, the same standards used by the Permitted Lessee with respect
to similar aircraft of similar size in its fleet and operated by the Permitted Lessee in similar
circumstances (it being understood that this clause (ii) shall not limit Owner’s obligations under
the preceding clause (i)). Owner further agrees that the Aircraft, Airframe and Engines will be
maintained, used, serviced, repaired, overhauled or inspected in compliance with applicable Laws
with respect to the maintenance of the Aircraft and in compliance with each applicable
airworthiness certificate, license and registration relating to the Aircraft, Airframe or any
Engine issued by the Aviation Authority, other than minor or nonrecurring violations with respect
to which corrective measures are taken upon discovery thereof and except to the extent Owner or
Permitted Lessee is contesting in good faith the validity or application of any such Law or
requirement relating to any such certificate, license or registration in any reasonable manner
which does not create a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or
any Engine or the interest of Mortgagee therein, or any

30

 

material risk of criminal liability or material civil penalty against Mortgagee. The Owner
shall maintain or cause to be maintained the Aircraft Documents in the English language.

               (e) Registration. The Owner on or prior to the date of the Closing shall cause the
Aircraft to be duly registered in its name under the Act and except as otherwise permitted by this
Section 4.02(e) at all times thereafter shall cause the Aircraft to remain so registered. So long
as no Special Default or Event of Default shall have occurred and be continuing, Owner may, by
written notice to Mortgagee, request to change the country of registration of the Aircraft. Any
such change in registration shall be effected only in compliance with, and subject to all of the
conditions set forth in, Section 6.4.5 of the Participation Agreement. Unless the Lien of this
Trust Indenture has been released, Owner shall also cause the Trust Indenture to be duly recorded
and at all times maintained of record as a first-priority perfected mortgage (subject to Permitted
Liens) on the Aircraft, the Airframe and each of the Engines (except to the extent such perfection
or priority cannot be maintained solely as a result of the failure by Mortgagee to execute and
deliver any necessary documents). Unless the Lien of this Trust Indenture has been released, Owner
shall cause the International Interest granted under this Indenture in favor of the Mortgagee in
each Airframe and Engine to be registered on the International Registry as an International
Interest on such Airframe and Engine, subject to the Mortgagee providing its consent to the
International Registry with respect thereto.

               (f) Markings. If permitted by applicable Law, on or reasonably promptly after the
Closing Date, Owner will cause to be affixed to, and maintained in, the cockpit of the Airframe and
on each Engine, in each case, in a clearly visible location, a placard of a reasonable size and
shape bearing the legend: “Subject to a security interest in favor of Wilmington Trust Company,
not in its individual capacity but solely as Mortgagee.” Such placards may be removed temporarily,
if necessary, in the course of maintenance of the Airframe or Engines. If any such placard is
damaged or becomes illegible, Owner shall promptly replace it with a placard complying with the
requirements of this Section.

          SECTION 4.03. Inspection

               (a) At all reasonable times, so long as the Aircraft is subject to the Lien of this Trust
Indenture, Mortgagee and its authorized representatives (the “Inspecting Parties”) may (not more
than once every 12 months unless an Event of Default has occurred and is continuing then such
inspection right shall not be so limited) inspect the Aircraft, Airframe and Engines (including
without limitation, the Aircraft Documents) and any such Inspecting Party may make copies of such
Aircraft Documents not reasonably deemed confidential by Owner or such Permitted Lessee.

               (b) Any inspection of the Aircraft hereunder shall be limited to a visual, walk-around
inspection and shall not include the opening of any panels, bays or other components of the
Aircraft, and no such inspection shall interfere with Owner’s or any Permitted Lessee’s maintenance
and operation of the Aircraft, Airframe and Engines.

               (c) With respect to such rights of inspection, Mortgagee shall not have any duty or liability
to make, or any duty or liability by reason of not making, any such visit, inspection or survey.

31

 

               (d) Each Inspecting Party shall bear its own expenses in connection with any such inspection
(including the cost of any copies made in accordance with Section 4.03(a)).

          SECTION 4.04. Replacement and Pooling of Parts, Alterations, Modifications and Additions;
Substitution of Engines

               (a) Replacement of Parts. Except as otherwise provided herein, so long as the
Airframe or Engine is subject to the Lien of this Trust Indenture, Owner, at its own cost and
expense, will, or will cause a Permitted Lessee to, at its own cost and expense, promptly replace
(or cause to be replaced) all Parts which may from time to time be incorporated or installed in or
attached to the Aircraft, Airframe or any Engine and which may from time to time become worn out,
lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit
for use for any reason whatsoever. In addition, Owner may, at its own cost and expense, or may
permit a Permitted Lessee at its own cost and expense to, remove (or cause to be removed) 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 permanently rendered
unfit for use; provided, however, that Owner, except as otherwise provided herein,
at its own cost and expense, will, or will cause a Permitted Lessee at its own cost and expense to,
replace such Parts as promptly as practicable. All replacement parts shall be free and clear of
all Liens, except for Permitted Liens and pooling arrangements to the extent permitted by Section
4.04(c) below (and except in the case of replacement property temporarily installed on an emergency
basis) and shall be in good operating condition and have a value and utility not less than the
value and utility of the Parts replaced (assuming such replaced Parts were in the condition
required hereunder).

               (b) Parts. Except as otherwise provided herein, any Part at any time removed from the
Airframe or any Engine shall remain subject to the Lien of this Trust Indenture, no matter where
located, until such time as such Part shall be replaced by a part that has been incorporated or
installed in or attached to such Airframe or any Engine and that meets the requirements for
replacement parts specified above. Immediately upon any replacement part becoming incorporated or
installed in or attached to such Airframe or any Engine as provided in Section 4.04(a), without
further act, (i) the replaced Part shall thereupon be free and clear of all rights of the Mortgagee
and shall no longer be deemed a Part hereunder, and (ii) such replacement part shall become a Part
subject to this Trust Indenture and be deemed part of such Airframe or any Engine, as the case may
be, for all purposes hereof to the same extent as the Parts originally incorporated or installed in
or attached to such Airframe or any Engine.

               (c) Pooling of Parts. Any Part removed from the Aircraft, Airframe or an Engine may
be subjected by the Owner or a Permitted Lessee to a normal pooling arrangement customary in the
airline industry and entered into in the ordinary course of business of Owner or Permitted Lessee,
provided that the part replacing such removed Part shall be incorporated or installed in or
attached to such Airframe or any Engine in accordance with Sections 4.04(a) and 4.04(b) 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 a normal pooling arrangement, so long as the Owner or a Permitted Lessee, at its
own cost and expense, as promptly thereafter as

32

 

reasonably possible, either (i) causes such
replacement part to become subject to the Lien of this Trust Indenture, free and clear of all Liens except Permitted Liens, at which time such
replacement part shall become a Part or (ii) replaces (or causes to be replaced) such replacement
part by incorporating or installing in or attaching to the Aircraft, Airframe or any Engine a
further replacement part owned by the Owner free and clear of all Liens except Permitted Liens and
which shall become subject to the Lien of this Trust Indenture in accordance with Section 4.04(b).

               (d) Alterations, Modifications and Additions. The Owner shall, or shall cause a
Permitted Lessee to, make (or cause to be made) alterations and modifications in and additions to
the Aircraft, Airframe and each Engine as may be required to be made from time to time to meet the
applicable standards of the FAA or other Aviation Authority having jurisdiction over the operation
of the Aircraft, to the extent made mandatory in respect of the Aircraft (a “Mandatory
Modification”); provided however, that the Owner or a Permitted Lessee may, in good
faith and by appropriate procedure, contest the validity or application of any law, rule,
regulation or order in any reasonable manner which does not materially adversely affect Mortgagee’s
interest in the Aircraft, does not impair the Mortgagee’s security interest in the Aircraft and
does not involve any material risk of sale, forfeiture or loss of the Aircraft or the interest of
Mortgagee therein, or any material risk of material civil penalty or any material risk of criminal
liability being imposed on Mortgagee or the holder of any Equipment Note. In addition, the Owner,
at its own expense, may, or may permit a Permitted Lessee at its own cost and expense to, from time
to time make or cause to be made such alterations and modifications in and additions to the
Airframe or any Engine (each an “Optional Modification”) as the Owner or such Permitted Lessee may
deem desirable in the proper conduct of its business including, without limitation, removal of
Parts which Owner deems are obsolete or no longer suitable or appropriate for use in the Aircraft,
Airframe or such Engine; provided, however, that no such Optional Modification
shall (i) materially diminish the fair market value, utility, or useful life of the Aircraft or any
Engine below its fair market value, utility or useful life immediately prior to such Optional
Modification (assuming the Aircraft or such Engine was in the condition required by this Trust
Indenture immediately prior to such Optional Modification) or (ii) cause the Aircraft to cease to
have the applicable standard certificate of airworthiness except that such certificate of
airworthiness temporarily may be replaced by an experimental certificate during the process of
implementing and testing such Optional Modification and securing related FAA re-certification of
the Aircraft. All Parts incorporated or installed in or attached to any Airframe or any Engine as
the result of any alteration, modification or addition effected by the Owner shall be free and
clear of any Liens except Permitted Liens and become subject to the Lien of this Trust Indenture;
provided that the Owner or any Permitted Lessee may, at any time so long as the Airframe or
any Engine is subject to the Lien of this Trust Indenture, remove any such Part (such Part being
referred to herein as a “Removable Part”) from such Airframe or an Engine if (i) such Part
is in addition to, and not in replacement of or in substitution for, any Part originally
incorporated or installed in or attached to such Airframe or any Engine at the time of delivery
thereof hereunder or any Part in replacement of, or in substitution for, any such original Part,
(ii) such Part is not required to be incorporated or installed in or attached or added to such
Airframe or any Engine pursuant to the terms of Section 4.02(d) or the first sentence of this
Section 4.04(d) and (iii) such Part can be removed from such Airframe or any Engine without
materially diminishing the fair market value, utility or remaining useful life which such Airframe
or any Engine would have had at the time of removal had such removal not been effected by the
Owner,

33

 

assuming the Aircraft was otherwise maintained in the condition required by this Trust
Indenture and such Removable Part had not been incorporated or installed in or attached to the Aircraft,
Airframe or such Engine. Upon the removal by the Owner of any such Part as above provided, title
thereto shall, without further act, be free and clear of all rights of the Mortgagee and such Part
shall no longer be deemed a Part hereunder. Removable Parts may be leased from or financed by
third parties other than Mortgagee.

               (e) Substitution of Engines. Upon the occurrence of an Event of Loss with respect to
an Engine under circumstances in which an Event of Loss with respect to the Airframe has not
occurred, Owner shall promptly (and in any event within 15 days after such occurrence) give the
Mortgagee written notice of such Event of Loss. The Owner shall have the right at its option at
any time, on at least 5 Business Days’ prior notice to the Mortgagee, to substitute, and if an
Event of Loss shall have occurred with respect to an Engine under circumstances in which an Event
of Loss with respect to the Airframe has not occurred, shall within 60 days of the occurrence of
such Event of Loss substitute, a Replacement Engine for any Engine. In such event, immediately
upon the effectiveness of such substitution and without further act, (i) the replaced Engine shall
thereupon be free and clear of all rights of the Mortgagee and the Lien of this Trust Indenture and
shall no longer be deemed an Engine hereunder and (ii) such Replacement Engine shall become subject
to this Trust Indenture and be deemed part of the Aircraft for all purposes hereof to the same
extent as the replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine
Manufacturer that is the same model as the Engine to be replaced thereby, or an improved model, and
that is suitable for installation and use on the Airframe, and that has a value, utility and
remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal
to the Engine to be replaced thereby (assuming that such Engine had been maintained in accordance
with this Trust Indenture). The Owner’s right to make a replacement hereunder shall be subject to
the fulfillment (which may be simultaneous with such replacement) of the following conditions
precedent at the Owner’s sole cost and expense, and the Mortgagee agrees to cooperate with the
Owner to the extent necessary to enable it to timely satisfy such conditions:

                    (i) an executed counterpart (or, in the case of subclause (B) below, a photocopy) of each of
the following documents shall be delivered to the Mortgagee:

     (A) a Trust Indenture Supplement covering the Replacement Engine, which shall
have been duly filed for recordation pursuant to the Act or such other applicable
law of the jurisdiction other than the United States in which the Aircraft of which
such Engine is a part is registered in accordance with Section 4.02(e), as the case
may be;

     (B) a full warranty bill of sale (as to title), covering the Replacement
Engine, executed by the former owner thereof in favor of the Owner (or, at the
Owner’s option, other evidence of the Owner’s ownership of such Replacement Engine,
reasonably satisfactory to the Mortgagee); and

     (C) UCC financing statements covering the security interests created by this
Trust Indenture (or any similar statements or other documents required to be filed
or delivered pursuant to the laws of the jurisdiction in which such Aircraft

34

 

may be
registered) as are deemed necessary or desirable by counsel for the
Mortgagee to protect the security interests of the Mortgagee in the Replacement
Engine;

                    (ii) the Owner shall cause to be delivered to the Mortgagee an opinion of counsel to the
effect that the Lien of this Trust Indenture continues to be in full force and effect with respect
to the Replacement Engine and such evidence of compliance with the insurance provisions of Section
4.06 with respect to such Replacement Engine as Mortgagee shall reasonably request;

                    (iii) the Owner shall have furnished to Mortgagee an opinion of Owner’s aviation law counsel
reasonably satisfactory to Mortgagee and addressed to Mortgagee as to the due filing for
recordation of the Trust Indenture Supplement with respect to such Replacement Engine under the Act
or such other applicable law of the jurisdiction other than the United States in which the Aircraft
is registered in accordance with Section 4.02(e), as the case may be, and the registration with the
International Registry of (i) the International Interest granted under such Trust Indenture
Supplement with respect to such Replacement Engine and (ii) if the bill of sale referred to in
clause (i)(B) above constitutes a “contract of sale” under the Cape Town Treaty, such contract of
sale with respect to such Replacement Engine; and

                    (iv) the Owner shall have furnished to Mortgagee a certificate of a qualified aircraft
engineer (who may be an employee of Owner) certifying that such Replacement Engine has a value and
utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at
least equal to the Engine so replaced (assuming that such Engine had been maintained in accordance
with this Trust Indenture).

Upon satisfaction of all conditions to such substitution, (x) the Mortgagee shall execute and
deliver to the Owner such documents and instruments, prepared at the Owner’s expense, as the Owner
shall reasonably request to evidence the release of such replaced Engine from the Lien of this
Trust Indenture, (y) the Mortgagee shall assign to the Owner all claims it may have against any
other Person relating to any Event of Loss giving rise to such substitution and (z) the Owner shall
receive all insurance proceeds (other than those reserved to others under Section 4.06(b)) and
proceeds in respect of any Event of Loss giving rise to such replacement to the extent not
previously applied to the purchase price of the Replacement Engine as provided in Section 4.05(d).

          SECTION 4.05. 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, the Owner shall promptly (and in any event within 15 days after
such occurrence) give the Mortgagee written notice of such Event of Loss. The Owner shall, within
45 days after such occurrence, give the Mortgagee written notice of Owner’s election to either
replace the Airframe as provided under Section 4.05(a)(i) or to make payment in respect of such
Event of Loss as provided under Section 4.05(a)(ii) (it being agreed that if Owner shall not have
given the Mortgagee such notice of such election within the above specified time period, the Owner
shall be deemed to have elected to make payment in respect of such Event of Loss as provided under
Section 4.05(a)(ii)):

35

 

                    (i) if Owner elects to replace the Airframe, Owner shall, subject to the satisfaction of the
conditions contained in Section 4.05(c), as promptly as possible and in any event within 120 days
after the occurrence of such Event of Loss, cause to be subjected to the Lien of this Trust
Indenture, in replacement of the Airframe with respect to which the Event of Loss occurred, a
Replacement Airframe and, if any Engine shall have been installed on the Airframe when it suffered
the Event of Loss, a Replacement Engine therefor, such Replacement Airframe and Replacement Engines
to be free and clear of all Liens except Permitted Liens and to have a value, utility and remaining
useful life (without regard to hours or cycles remaining until the next regular maintenance check)
at least equal to the Airframe or Engine, as the case may be, to be replaced thereby (assuming that
such Airframe or Engine had been maintained in accordance with this Trust Indenture);
provided that if the Owner shall not perform its obligation to effect such
replacement under this clause (i) during the 120-day period of time provided herein, it shall pay
the amounts required to be paid pursuant to and within the time frame specified in clause (ii)
below; or

                    (ii) if Owner elects to make a payment in respect of such Event of Loss of the Airframe, Owner
shall make a payment to the Mortgagee for purposes of redeeming Equipment Notes in accordance with
Section 2.10 hereof on a date on or before the Business Day next following the earlier of (x) the
120th day following the date of the occurrence of such Event of Loss, and (y) the fourth Business
Day following the receipt of insurance proceeds with respect to such Event of Loss (but in any
event not earlier than the date of Owner’s election under Section 4.05(a) to make payment under
this Section 4.05 (a)(ii)); and upon such payment and payment of all other Secured Obligations then
due and payable, the Mortgagee shall, at the cost and expense of the Owner, release from the Lien
of this Trust Indenture the Airframe and the Engines, by executing and delivering to the Owner all
documents and instruments as the Owner may reasonably request to evidence such release.

               (b) Effect of Replacement. Should the Owner have provided a Replacement Airframe and
Replacement Engines, if any, as provided for in Section 4.05(a)(i), (i) the Lien of this Trust
Indenture shall continue with respect to such Replacement Airframe and Replacement Engines, if any,
as though no Event of Loss had occurred; (ii) the Mortgagee shall, at the cost and expense of the
Owner, release from the Lien of this Trust Indenture the replaced Airframe and Engines, if any, by
executing and delivering to the Owner such documents and instruments as the Owner may reasonably
request to evidence such release; and (iii) in the case of a replacement upon an Event of Loss, the
Mortgagee shall assign to the Owner all claims the Mortgagee may have against any other Person
arising from the Event of Loss and the Owner shall receive all insurance proceeds (other than those
reserved to others under Section 4.06(b)) and proceeds from any award in respect of condemnation,
confiscation, seizure or requisition, including any investment interest thereon, to the extent not
previously applied to the purchase price of the Replacement Airframe and Replacement Engines, if
any, as provided in Section 4.05(d).

               (c) Conditions to Airframe and Engine Replacement. The Owner’s right to substitute a
Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(a)(i) shall be
subject to the fulfillment, at the Owner’s sole cost and expense, in addition to the conditions
contained in such Section 4.05(a)(i), of the following conditions precedent:

36

 

                    (i) on the date when the Replacement Airframe and Replacement Engines, if any, is subjected to
the Lien of this Trust Indenture (such date being referred to in this Section 4.05 as the
“Replacement Closing Date”), an executed counterpart of each of the following documents (or, in the
case of the FAA Bill of Sale and full warranty bill of sale referred to below, a photocopy thereof)
shall have been delivered to the Mortgagee:

     (A) a Trust Indenture Supplement covering the Replacement Airframe and
Replacement Engines, if any, which shall have been duly filed for recordation
pursuant to the Act or such other applicable law of such jurisdiction other than the
United States in which the Replacement Airframe and Replacement Engines, if any, are
to be registered in accordance with Section 4.02(e), as the case may be;

     (B) an FAA Bill of Sale (or a comparable document, if any, of another Aviation
Authority, if applicable) covering the Replacement Airframe executed by the former
owner thereof in favor of the Owner;

     (C) a full warranty (as to title) bill of sale, covering the Replacement
Airframe and Replacement Engines, if any, executed by the former owner thereof in
favor of the Owner (or, at the Owner’s option, other evidence of the Owner’s

the Mortgagee to protect the security interests of the Mortgagee in the Replacement
Airframe and Replacement Engines, if any;

                    (ii) the Replacement Airframe and Replacement Engines, if any, shall be of the same model as
the Airframe or Engines, as the case may be, or an improved model of such aircraft or engines of
the manufacturer thereof, shall have a value, utility and remaining useful life(without regard to
hours or cycles remaining until the next regular maintenance check) at least equal to, and be in as
good operating condition and repair as, the Airframe and any Engines replaced (assuming such
Airframe and Engines had been maintained in accordance with this Trust Indenture);

                    (iii) the Mortgagee (acting directly or by authorization to its special counsel) shall have
received satisfactory evidence as to the compliance with Section 4.06 with respect to the
Replacement Airframe and Replacement Engines, if any;

                    (iv) on the Replacement Closing Date, (A) the Owner shall cause the Replacement Airframe and

                    (v) the Mortgagee at the expense of the Owner, shall have received (acting directly or by

effect that the Replacement Airframe and Replacement Engine, if any, has or have duly been made
subject to the Lien of this Trust Indenture, and Mortgagee will be entitled to the benefits of
Section 1110 with respect to the Replacement Airframe, provided that such opinion with respect to
Section 1110 need not be delivered to the extent that immediately prior to such replacement the
benefits of Section 1110 were not, solely by reason of a change in law or court interpretation
thereof, available to Mortgagee, and (B) an opinion of Owner’s aviation law counsel reasonably
satisfactory to and addressed to Mortgagee as to the due registration of any such Replacement
Airframe and the due filing for recordation of each Trust Indenture Supplement with respect to such

(assuming that such Airframe and Engines had been maintained in accordance with this Trust
Indenture).

          (d) Non-Insurance Payments Received on Account of an Event of Loss. Any amounts,
other than insurance proceeds in respect of damage or loss not constituting an Event of Loss (the
application of which is provided for in Annex B), received at any time by Mortgagee or Owner from
any Government Entity or any other Person in respect of any Event of Loss will be applied as
follows:

     (i) If such amounts are received with respect to the Airframe, and any Engine
installed thereon at the time of such Event of Loss, upon compliance by Owner with
the applicable terms of Section 4.05(c) with respect to the Event of Loss for which
such amounts are received, such amounts shall be paid over to, or retained by,
Owner;

     (ii) If such amounts are received with respect to an Engine (other than an
Engine installed on the Airframe at the time such Airframe suffers an Event of
Loss), upon compliance by Owner with the applicable terms of Section 4.04(e)

38

 

with respect to the Event of Loss for which such amounts are received, such amounts shall
be paid over to, or retained by, Owner;

     (iii) If such amounts are received, in whole or in part, with respect to the
Airframe, and Owner makes, has made or is deemed to have made the election set forth
in Section 4.05(a)(ii), such amounts shall be applied as follows:

          first, if the sum described in Section 4.05(a)(ii) has not then been
paid in full by Owner, such amounts shall be paid to Mortgagee to the extent
necessary to pay in full such sum; and

          second, the remainder, if any, shall be paid to Owner.

               (e) Requisition for Use. In the event of a requisition for use by any Government
Entity of the Airframe and the Engines, if any, or engines installed on such Airframe while such
Airframe is subject to the Lien of this Trust Indenture, the Owner shall promptly notify the
Mortgagee of such requisition and all of the Owner’s obligations under this Trust Indenture shall
continue to the same extent as if such requisition had not occurred except to the extent that the
performance or observance of any obligation by the Owner shall have been prevented or delayed by
such requisition; provided that the Owner’s obligations under this Section 4.05
with respect to the occurrence of an Event of Loss for the payment of money and under Section 4.06
(except while an assumption of liability by the U.S. Government of the scope referred to in Section
4.02(c) is in effect) shall not be reduced or delayed by such requisition. Any payments received
by the Mortgagee or the Owner or Permitted Lessee from such Government Entity with respect to such
requisition of use shall be paid over to, or retained by, the Owner. In the event of an Event of
Loss of an Engine resulting from the requisition for use by a Government Entity of such Engine (but
not the Airframe), the Owner will replace such Engine hereunder by complying with the terms of
Section 4.04(e) and any payments received by the Mortgagee or the Owner from such Government Entity
with respect to such requisition shall be paid over to, or retained by, the Owner.

               (f) Certain Payments to be Held As Security. Any amount referred to in this Section
4.05 or Section 4.06 which is payable or creditable to, or retainable by, the Owner shall not be
paid or credited to, or retained by the Owner if at the time of such payment, credit or retention a
Special Default or an Event of Default shall have occurred and be continuing, but shall be paid to
and held by the Mortgagee as security for the obligations of the Owner under this Trust Indenture
and the Operative Agreements, and at such time as there shall not be continuing any such Special
Default or Event of Default such amount and any gain realized as a result of investments required
to be made pursuant to Section 6.06 shall to the extent not theretofore applied as provided herein,
be paid over to the Owner.

          SECTION 4.06. Insurance

               (a) Owner’s Obligation to Insure. Owner shall comply with, or cause to be complied
with, each of the provisions of Annex B, which provisions are hereby incorporated by this reference
as if set forth in full herein.

39

 

               (b) Insurance for Own Account. Nothing in Section 4.06 shall limit or prohibit (a)
Owner from maintaining the policies of insurance required under Annex B with higher limits than
those specified in Annex B, or (b) Mortgagee from obtaining insurance for its own account (and any
proceeds payable under such separate insurance shall be payable as provided in the policy relating
thereto); provided, however, that no insurance may be obtained or maintained that
would limit or otherwise adversely affect the coverage of any insurance required to be obtained or
maintained by Owner pursuant to this Section 4.06 and Annex B.

               (c) Indemnification by Government in Lieu of Insurance. Mortgagee agrees to accept,
in lieu of insurance against any risk with respect to the Aircraft described in Annex B,
indemnification from, or insurance provided by, the U.S. Government, or upon the written consent of
Mortgagee, other Government Entity, against such risk in an amount that, when added to the amount
of insurance (including permitted self-insurance), if any, against such risk that Owner (or any
Permitted Lessee) may continue to maintain, in accordance with this Section 4.06, shall be at least
equal to the amount of insurance against such risk otherwise required by this Section 4.06.

               (d) Application of Insurance Proceeds. As between Owner and Mortgagee, all insurance
proceeds received as a result of the occurrence of an Event of Loss with respect to the Aircraft or
any Engine under policies required to be maintained by Owner pursuant to this Section 4.06 will be
applied in accordance with Section 4.05(d). All proceeds of insurance required to be maintained by
Owner, in accordance with Section 4.06 and Section B of Annex B, in respect of any property damage
or loss not constituting an Event of Loss with respect to the Aircraft, Airframe or any Engine will
be applied in payment (or to reimburse Owner) for repairs or for replacement property, and any
balance remaining after such repairs or replacement with respect to such damage or loss shall be
paid over to, or retained by, Owner.

          SECTION 4.07. Merger of Owner

               (a) In General. Owner shall not consolidate with or merge into any other person under
circumstances in which Owner is not the surviving person, or convey, transfer or lease in one or
more transactions all or substantially all of its assets to any other person, unless:

                    (i) such person is organized, existing and in good standing under the Laws of the United
States, any State of the United States or the District of Columbia and, upon consummation of such
transaction, such person will be a U.S. Air Carrier if, and so long as, such status is a condition
of entitlement to the benefits of Section 1110 with respect to the Aircraft;

                    (ii) such person executes and delivers to Mortgagee a duly authorized, legal, valid, binding
and enforceable agreement, reasonably satisfactory in form and substance to Mortgagee, containing
an effective assumption by such person of the due and punctual performance and observance of each
covenant, agreement and condition in the Operative Agreements to be performed or observed by Owner;

                    (iii) if the Aircraft is, at the time, registered with the FAA, such person makes such filings
and recordings with the FAA pursuant to the Act or if the Aircraft is,

40

 

at the time, not registered
with FAA, such person makes such filings and recordings with the applicable Aviation Authority as
shall be necessary to evidence such consolidation or merger; and such person makes such filings and
recordings, if any, with the International Registry, to reflect such change as may be necessary.

                    (iv) immediately after giving effect to such consolidation or merger no Event of Default shall
have occurred and be continuing.

               (b) Effect of Merger. Upon any such consolidation or merger of Owner with or into, or
the conveyance, transfer or lease by Owner of all or substantially all of its assets to, any Person
in accordance with this Section 4.07, such Person will succeed to, and be substituted for, and may
exercise every right and power of, Owner under the Operative Agreements with the same effect as if
such person had been named as “Owner” therein. In the event of any such conveyance, transfer or
lease, the Company or any successor Person that shall have become such in the manner prescribed in
this Section 4.07 shall be released and discharged from its liability in respect of this Trust
Indenture and the Equipment Certificates and may be dissolved and liquidated.

any order, rule or regulation of any administrative or governmental body):

                    (i) the failure of the Owner to pay (i) principal of, interest on or Make-Whole Amount, if

                    (ii) Owner shall fail to carry and maintain, or cause to be carried and maintained, insurance
on and in respect of the Aircraft, Airframe and Engines in accordance with the provisions of

of such lapse or cancellation of (ii) the date that such lapse or cancellation is effective as to
the Mortgagee;

                    (iii) Owner shall fail to observe or perform (or caused to be observed and performed) in any
material respect any other covenant, agreement or obligation set forth herein or in any other
Operative Agreement to which Owner is a party and such failure shall continue unremedied for a
period of 60 days from and after the date of written notice thereof to Owner from Mortgagee, unless
such failure is capable of being corrected and Owner

41

 

shall be diligently proceeding to correct such
failure, in which case there shall be no Event of Default unless and until such failure shall
continue unremedied for a period of 360 days after receipt of such notice;

                    (iv) any representation or warranty made by Owner herein, in the Participation Agreement or in
any other Operative Agreement to which Owner is a party (a) shall prove to have been untrue or
inaccurate in any material respect as of the date made, (b) such untrue or inaccurate
representation or warranty is material at the time in question, (c) and the same shall remain
uncured (to the extent of the adverse impact of such incorrectness on the interest of the
Mortgagee) for a period in excess of 60 days from and after the date of written notice thereof from
Mortgagee to Owner;

                    (v) the Owner shall consent to the appointment of or taking possession by a receiver, trustee
or liquidator of itself or of a substantial part of its property, or the Owner shall admit in
writing its inability to pay its debts generally as they come due or shall make a general
assignment for the benefit of its creditors, or the Owner shall file a voluntary petition in
bankruptcy or a voluntary petition or an answer seeking reorganization, liquidation or other relief
under any bankruptcy laws or insolvency laws (as in effect at such time), or an answer admitting
the material allegations of a petition filed against it in any such case, or the Owner shall seek
relief by voluntary petition, answer or consent, under the provisions of any other bankruptcy or
similar law providing for the reorganization or winding-up of corporations (as in effect at such
time), or the Owner shall seek an agreement, composition, extension or adjustment with its
creditors under such laws or the Owner’s board of directors shall adopt a resolution authorizing
corporate action in furtherance of any of the foregoing;

                    (vi) an order, judgment or decree shall be entered by any court of competent jurisdiction
appointing, without the consent of the Owner, a receiver, trustee or liquidator of the Owner or of
any substantial part of its property, or any substantial part of the property of the Owner shall be
sequestered, or granting any other relief in respect of the Owner as a debtor under any bankruptcy

thereafter, or if, under the provisions of any law providing for reorganization or winding-up of
corporations which may apply to the Owner, any court of competent jurisdiction shall assume
jurisdiction, custody or control of the Owner of any substantial part of its property and such
jurisdiction, custody or control shall remain in force unrelinquished, unstayed or unterminated for
a period of 90 days; or

                    (viii) (A) any amount in respect of (i) the Related Equipment Notes, including any payment of

the third paragraph of Section 2.02 of any Related Indenture and any indemnities payable by the
Owner pursuant to Section 8.1 of any Related

42

 

Participation Agreement) in each case that are due and
payable on or before the Final Payment Date are not paid in full on the Final Payment Date and (B)
any such failure shall continue unremedied for a period of twenty (20) Business Days thereafter.

provided, however, that, notwithstanding anything to the contrary contained in this Section 5.01,
any failure of Owner to perform or observe any covenant, condition, agreement or any error in a
representation or warranty shall not constitute an Event of Default if such failure or error is
caused solely by reason of any event that constitutes an Event of Loss so long as Owner is
continuing to comply with all of the terms of Section 4.04(e) and Section 4.05 hereof.

          SECTION 5.02. Remedies

               (a) If an Event of Default shall have occurred and be continuing and so long as the same shall
continue unremedied, then and in every such case the Mortgagee may exercise any or all of the
rights and powers and pursue any and all of the remedies pursuant to this Article V and shall have
and may exercise all of the rights and remedies of a secured party under the Uniform Commercial
Code or by any other applicable Law (including the Cape Town Treaty, to the extent applicable) and
may take possession of all or any part of the properties covered or intended to be covered by the
Lien created hereby or pursuant hereto and may exclude the Owner and all persons claiming under it
wholly or partly therefrom; provided, that the Mortgagee shall give the Owner twenty (20)
days’ prior written notice of its intention to sell the Aircraft. Without limiting any of the
foregoing, it is understood and agreed that the Mortgagee may exercise any right of sale of the
Aircraft available to it, even though it shall not have taken possession of the Aircraft and shall
not have possession thereof at the time of such sale.

               (b) If an Event of Default shall have occurred and be continuing, then and in every such case
the Mortgagee may (and shall, upon receipt of a written demand therefor from a Majority in Interest
of Note Holders), at any time, by delivery of written notice or notices to the Owner, declare all
the Equipment Notes to be due and payable, whereupon the unpaid Original Amount of all Equipment
Notes then outstanding, together with accrued but unpaid interest thereon (without Make-Whole
Amount) and other amounts due thereunder or otherwise payable hereunder, 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 clause (v), (vi) or (vii) of Section 5.01
hereof shall have occurred, then and in every such case the unpaid Original Amount then
outstanding, together with accrued but unpaid interest (without Make-Whole Amount) and all other
amounts due hereunder and under the Equipment Notes shall immediately and without further act
become due and payable without presentment, demand, protest or notice, all of which are hereby
waived.

          This Section 5.02(b), however, is subject to the condition that, if at any time after the
Original Amount of the Equipment Notes shall have become so due and payable, and before any
judgment or decree for the payment of the money so due, or any thereof, shall be entered, all
overdue payments of interest upon the Equipment Notes and all other amounts payable hereunder or
under the Equipment Notes (except the Original Amount of the Equipment Notes which by such
declaration shall have become payable) shall have been duly paid, and every other Default and Event
of Default with respect to any covenant or provision of this Trust Indenture

43

 

shall have been cured,
then and in every such case a Majority in Interest of Note Holders may (but shall not be obligated
to), by written instrument filed with the Mortgagee, rescind and annul the Mortgagee’s declaration
(or such automatic acceleration) and its consequences; but no such rescission or annulment shall
extend to or affect any subsequent Default or Event of Default or impair any right consequent
thereon.

               (c) The Note Holders shall be entitled, at any sale pursuant to this Section 5.02, to credit
against any purchase price bid at such sale by such holder all or any part of the unpaid
obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (only to the
extent that such purchase price would have been paid to such Note Holder pursuant to Article III
hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c)
were not given effect).

               (d) In the event of any sale of the Collateral, or any part thereof, pursuant to any judgment
or decree of any court or otherwise in connection with the enforcement of any of the terms of this
Trust Indenture, the unpaid Original Amount of all Equipment Notes then outstanding, together with
accrued interest thereon (without Make-Whole Amount), and other amounts due thereunder, shall
immediately become due and payable without presentment, demand, protest or notice, all of which are
hereby waived.

               (e) Notwithstanding anything contained herein, (i) so long as the Pass Through Trustee under
any Pass Through Trust Agreement (or its designee) is a Note Holder, the Mortgagee 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 Trust to fail to qualify
as a “grantor trust” for federal income tax purposes, and (ii) the Mortgagee will not take any
action that would violate Section 4.1(a)(ii) or 4.1(a)(iii) of the Intercreditor Agreement.

          SECTION 5.03. Return of Aircraft, Etc.

               (a) If an Event of Default shall have occurred and be continuing and the Equipment Notes have
been accelerated, at the request of the Mortgagee, the Owner shall promptly execute and deliver to
the Mortgagee such instruments of title and other documents as the Mortgagee may deem necessary or
advisable to enable the Mortgagee or an agent or representative designated by the Mortgagee, at
such time or times and place or places as the Mortgagee may specify, to obtain possession of all or
any part of the Collateral to which the Mortgagee shall at the time be entitled hereunder. If the
Owner shall for any reason fail to execute and deliver such instruments and documents after such
request by the Mortgagee, the Mortgagee may (i) obtain a judgment conferring on the Mortgagee the
right to immediate possession and requiring the Owner to execute and deliver such instruments and documents to
the Mortgagee, to the entry of which judgment the Owner hereby specifically consents to the fullest
extent permitted by Law, and (ii) pursue all or part of such Collateral wherever it may be found
and may enter any of the premises of Owner wherever such Collateral may be or be supposed to be and
search for such Collateral and take possession of and remove such Collateral. All expenses of
obtaining such judgment or of pursuing, searching for and taking such property shall, until paid,
be secured by the Lien of this Trust Indenture.

44

 

               (b) Upon every such taking of possession, the Mortgagee may, from time to time, at the expense
of the Collateral, make all such expenditures for maintenance, use, operation, storage, insurance,
leasing, control, management, disposition, modifications or alterations to and of the Collateral,
as it may deem proper. In each such case, the Mortgagee shall have the right to maintain, use,
operate, store, insure, lease, control, manage, dispose of, modify or alter the Collateral and to
exercise all rights and powers of the Owner relating to the Collateral, as the Mortgagee shall deem
best, including the right to enter into any and all such agreements with respect to the
maintenance, use, operation, storage, insurance, leasing, control, management, disposition,
modification or alteration of the Collateral or any part thereof as the Mortgagee may determine,
and the Mortgagee shall be entitled to collect and receive directly all rents, revenues and other
proceeds of the Collateral and every part thereof, without prejudice, however, to the right of the
Mortgagee under any provision of this Trust Indenture to collect and receive all cash held by, or
required to be deposited with, the Mortgagee hereunder. Such rents, revenues and other proceeds
shall be applied to pay the expenses of the maintenance, use, operation, storage, insurance,
leasing, control, management, disposition, improvement, modification or alteration of the
Collateral and of conducting the business thereof, and to make all payments which the Mortgagee may
be required or may elect to make, if any, for taxes, assessments, insurance or other proper charges
upon the Collateral or any part thereof (including the employment of engineers and accountants to
examine, inspect and make reports upon the properties and books and records of the Owner), and all
other payments which the Mortgagee may be required or authorized to make under any provision of
this Trust Indenture, as well as just and reasonable compensation for the services of the
Mortgagee, and of all persons properly engaged and employed by the Mortgagee with respect hereto.

          SECTION 5.04. Remedies Cumulative

          Each and every right, power and remedy given to the Mortgagee specifically or otherwise in
this Trust Indenture shall be cumulative and shall be in addition to every other right, power and
remedy herein specifically given or now or hereafter existing at Law, in equity or by statute, and
each and every right, power and remedy whether specifically herein given or otherwise existing may
be exercised from time to time and as often and in such order as may be deemed expedient by the
Mortgagee, 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 the Mortgagee in the exercise of any right, remedy or
power or in the pursuance of any remedy shall impair any such right, power or remedy or be
construed to be a waiver of any default on the part of the Owner or to be an acquiescence therein.

          SECTION 5.05. Discontinuance of Proceedings

          In case the Mortgagee shall have instituted any proceeding to enforce any right, power or
remedy under this Trust Indenture by foreclosure, entry or otherwise, and such proceedings shall
have been discontinued or abandoned for any reason or shall have been determined adversely to the
Mortgagee, then and in every such case the Owner and the Mortgagee 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 the Owner or the Mortgagee shall
continue as if no such proceedings had been instituted.

45

 

          SECTION 5.06. Waiver of Past Defaults

          Upon written instruction from a Majority in Interest of Note Holders, the Mortgagee 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 Trust Indenture, 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 all the Note Holders, the Mortgagee shall not waive any Default (i) in the
payment of the Original Amount, Make-Whole Amount, if any, and interest and other amounts due under
any Equipment Note then outstanding, or (ii) in respect of a covenant or provision hereof which,
under Article X hereof, cannot be modified or amended without the consent of each Note Holder.

          SECTION 5.07. Appointment of Receiver

          The Mortgagee shall, as a matter of right, be entitled to the appointment of a receiver (who
may be the Mortgagee or any successor or nominee thereof) for all or any part of the Collateral
after the occurrence and during the continuance of an Event of Default, whether such receivership
be incidental to a proposed sale of the Collateral or the taking of possession thereof or
otherwise, and the Owner 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 the Mortgagee with respect to the Collateral.

          SECTION 5.08. Mortgagee Authorized to Execute Bills of Sale, Etc.

          The Owner irrevocably appoints, while an Event of Default has occurred and is continuing, the
Mortgagee the true and lawful attorney-in-fact of the Owner (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 Trust Indenture, whether
pursuant to foreclosure or power of sale, assignments and other instruments as may be necessary or
appropriate, with full power of substitution, the Owner hereby ratifying and confirming all that
such attorney or any substitute shall do by virtue hereof in accordance with applicable law.
Nevertheless, if so requested by the Mortgagee or any purchaser, the Owner shall ratify and confirm any such sale, assignment, transfer or delivery,
by executing and delivering to the Mortgagee or such purchaser all bills of sale, assignments,
releases and other proper instruments to effect such ratification and confirmation as may be
designated in any such request.

          SECTION 5.09. Rights of Note Holders to Receive Payment

          Notwithstanding any other provision of this Trust Indenture, the right of any Note Holder to
receive payment of principal of, and premium, if any, and interest on an Equipment Note on or after

ARTICLE VI

DUTIES OF THE MORTGAGEE

          SECTION 6.01. Notice of Event of Default

          If the Mortgagee shall have Actual Knowledge of an Event of Default or of a Default arising
from a failure to pay any installment of principal and interest on any Equipment Note, the
Mortgagee shall give prompt written notice thereof to each Note Holder. Subject to the terms of
Sections 5.06, 6.02 and 6.03 hereof, the Mortgagee shall take such action, or refrain from taking
such action, with respect to such Event of Default or Default (including with respect to the
exercise of any rights or remedies hereunder) as the Mortgagee shall be instructed in writing by a
Majority in Interest of Note Holders. Subject to the provisions of Section 6.03, if the Mortgagee
shall not have received instructions as above provided within 20 days after mailing notice of such
Event of Default to the Note Holders, the Mortgagee may, subject to instructions thereafter
received pursuant to the preceding provisions of this Section 6.01, take such action, or refrain
from taking such action, but shall be under no duty to take or refrain from taking any action, with
respect to such Event of Default or Default as it shall determine advisable in the best interests
of the Note Holders; provided, however, that the Mortgagee may not sell the
Aircraft or any Engine without the consent of a Majority in Interest of Note Holders. For all
purposes of this Trust Indenture, in the absence of Actual Knowledge on the part of the Mortgagee,
the Mortgagee shall not be deemed to have knowledge of a Default or an Event of Default (except the
failure of Owner to pay any installment of principal or interest within one Business Day after the
same shall become due, which failure shall constitute knowledge of a Default) unless notified in
writing by the Owner or one or more Note Holders.

          SECTION 6.02. Action Upon Instructions; Certain Rights and Limitations

          Subject to the terms of Sections 5.02(a), 5.06, 6.01 and 6.03 hereof, upon the written
instructions at any time and from time to time of a Majority in Interest of Note Holders, the
Mortgagee shall, subject to the terms of this Section 6.02, take such of the following actions as
may be specified in such instructions: (i) give such notice or direction or exercise such right,
remedy or power hereunder as shall be specified in such instructions and (ii) give such notice or
direction or exercise such right, remedy or power hereunder with respect to any part of the
Collateral as shall be specified in such instructions; it being understood that without the written
instructions of a Majority in Interest of Note Holders, the Mortgagee shall not, except as provided
in Section 6.01, approve any such matter as satisfactory to the Mortgagee.

          The Mortgagee will execute and the Owner will file such continuation statements with respect
to financing statements relating to the security interest created hereunder in the Collateral as
may be specified from time to time in written instructions of a Majority in Interest of Note
Holders (which instructions shall be accompanied by the form of such continuation statement so to
be filed). The Mortgagee will furnish to each Note Holder, promptly upon receipt thereof,
duplicates or copies of all reports, notices, requests, demands, certificates and other instruments
furnished to the Mortgagee hereunder.

47

 

          SECTION 6.03. Indemnification

          The Mortgagee shall not be required to take any action or refrain from taking any action under
Section 6.01 (other than the first sentence thereof), 6.02 or Article V hereof unless the Mortgagee
shall have been indemnified to its reasonable satisfaction against any liability, cost or expense
(including counsel fees) which may be incurred in connection therewith pursuant to a written
agreement with one or more Note Holders. The Mortgagee agrees that it shall look solely to the
Note Holders for the satisfaction of any indemnity (except expenses for foreclosure of the type
referred to in clause “First” of Section 3.03 hereof) owed to it pursuant to this Section 6.03.
The Mortgagee shall not be under any obligation to take any action under this Trust Indenture or
any other Operative Agreement and nothing herein or therein shall require the Mortgagee to expend
or risk its own funds or otherwise incur the risk of any financial liability in the performance of
any of its rights or powers if it shall have reasonable grounds for believing that repayment of
such funds or adequate indemnity against such risk or liability is not reasonably assured to it
(the written indemnity of any Note Holder who is a QIB, signed by an authorized officer thereof, in
favor of, delivered to and in form reasonably satisfactory to the Mortgagee shall be accepted as
reasonable assurance of adequate indemnity). The Mortgagee shall not be required to take any
action under Section 6.01 (other than the first sentence thereof) or 6.02 or Article V hereof, nor
shall any other provision of this Trust Indenture or any other Operative Agreement be deemed to
impose a duty on the Mortgagee to take any action, if the Mortgagee shall have been advised by
counsel that such action is contrary to the terms hereof or is otherwise contrary to Law.

          SECTION 6.04. No Duties Except as Specified in Trust Indenture or Instructions

          The Mortgagee shall not have any duty or obligation to use, operate, store, lease, control,
manage, sell, 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 Trust
Indenture or any part of the Collateral, except as expressly provided by the terms of this Trust
Indenture or as expressly provided in written instructions from Note Holders as provided in this
Trust Indenture; and no implied duties or obligations shall be read into this Trust Indenture
against the Mortgagee. The Mortgagee agrees that it will in its individual capacity and at its own
cost and expense (but without any right of indemnity in respect of any such cost or expense under
Section 8.01 hereof), promptly take such action as may be necessary duly to discharge all Liens on
any part of the Collateral which result from claims against it in its individual capacity not
related to the administration of the Collateral or any other transaction pursuant to this Trust
Indenture or any document included in the Collateral.

          SECTION 6.05. No Action Except Under Trust Indenture or Instructions

          The Mortgagee will not use, operate, store, lease, control, manage, sell, 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 the Mortgagee pursuant to this Trust Indenture
and in accordance with the express terms hereof.

48

 

          SECTION 6.06. Investment of Amounts Held by Mortgagee

          Any amounts held by the Mortgagee pursuant to Section 3.02, 3.03 or 3.07 or pursuant to any
provision of any other Operative Agreement providing for amounts to be held by the Mortgagee which
are not distributed pursuant to the other provisions of Article III hereof shall be invested by the
Mortgagee from time to time in Cash Equivalents as directed by the Owner so long as the Mortgagee
may acquire the same using its best efforts. All Cash Equivalents held by the Mortgagee pursuant
to this Section 6.06 shall either be (a) registered in the name of, payable to the order of, or
specially endorsed to, the Mortgagee, or (b) held in an Eligible Account. Unless otherwise
expressly provided in this Trust Indenture, any income realized as a result of any such investment,
net of the Mortgagee’s reasonable fees and expenses in making such investment, shall be held and
applied by the Mortgagee in the same manner as the principal amount of such investment is to be
applied and any losses, net of earnings and such reasonable fees and expenses, shall be charged
against the principal amount invested. The Mortgagee shall not be liable for any loss resulting
from any investment required to be made by it under this Trust Indenture other than by reason of
its willful misconduct or negligence in the handling of funds, and any such investment may be sold
(without regard to its maturity) by the Mortgagee without instructions whenever such sale is
necessary to make a distribution required by this Trust Indenture.

ARTICLE VII

same but only upon the terms of this Trust Indenture and agrees to receive and disburse all monies
constituting part of the Collateral in accordance with the terms hereof. The Mortgagee, in its
individual capacity, shall not be answerable or accountable under any circumstances, except (i) for
its own willful misconduct or gross negligence (other than for the handling of funds actually
received by it in accordance with the terms of the Operative Agreements or the Pass Through
Agreements, for which the standard of accountability shall be willful misconduct or negligence),
(ii) as provided in the fourth sentence of Section 2.04(a) hereof and the last sentence of Section
6.04 hereof, and (iii) from the inaccuracy of any representation or warranty of the Mortgagee (in
its individual capacity) in the Participation Agreement or expressly made hereunder.

          SECTION 7.02. Absence of Duties

          Except in accordance with written instructions furnished pursuant to Section 6.01 or 6.02
hereof, and except as provided in, and without limiting the generality of, Sections 6.03, 6.04 and
7.07 hereof the Mortgagee shall have no duty (i) to see to any registration of the Aircraft or any
recording or filing of this Trust Indenture or any other document, or to see to the maintenance of
any such registration, recording or filing, (ii) to see to any insurance on the Aircraft or to
effect or maintain any such insurance, whether or not Owner shall be in default with respect
thereto, (iii) to see to the payment or discharge of any Lien of any kind against any

49

 

part of the
Collateral, (iv) to confirm, verify or inquire into the failure to receive any financial statements
from Owner, or (v) to inspect the Aircraft at any time or ascertain or inquire as to the
performance or observance of any of Owner’s covenants herein or any Permitted Lessee’s covenants
under any assigned Permitted Lease with respect to the Aircraft.

          SECTION 7.03. No Representations or Warranties as to Aircraft or Documents

          THE MORTGAGEE IN ITS INDIVIDUAL OR TRUST CAPACITY DOES NOT MAKE AND SHALL NOT BE DEEMED TO
HAVE MADE AND HEREBY EXPRESSLY DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO
THE TITLE, AIRWORTHINESS, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, DESIGN, QUALITY,
DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR USE FOR A PARTICULAR PURPOSE OF THE AIRCRAFT
OR ANY ENGINE, AS TO THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE
ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, AS TO THE ABSENCE OF OBLIGATIONS
BASED ON STRICT LIABILITY IN TORT OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER. The Mortgagee, in its individual or trust capacities,
does not make nor shall it be deemed to have made any representation or warranty as to the
validity, legality or enforceability of this Trust Indenture, the Participation Agreement, the
Equipment Notes, or the Purchase Agreement, or as to the correctness of any statement contained in
any thereof, except for the representations and warranties of the Mortgagee in its individual
capacity, in each case expressly made in this Trust Indenture or in the Participation Agreement.
The Note Holders make no representation or warranty hereunder whatsoever.

          SECTION 7.04. No Segregation of Monies; No Interest

          Except as otherwise provided in Section 3.07 hereof, any monies paid to or retained by the
Mortgagee pursuant to any provision hereof and not then required to be distributed to the Note
Holders, or the Owner as provided in Article III hereof need not be segregated in any manner except
to the extent required by Law or Section 6.06 hereof, and may be deposited under such general
conditions as may be prescribed by Law, and the Mortgagee shall not be liable for any interest
thereon (except that the Mortgagee shall invest all monies held as directed by Owner so long as no
Event of Default has occurred and is continuing (or in the absence of such direction, by the
Majority in Interest of Note Holders) in Cash Equivalents; provided, however, that
any payments received, or applied hereunder, by the Mortgagee shall be accounted for by the
Mortgagee so that any portion thereof paid or applied pursuant hereto shall be identifiable as to
the source thereof.

          SECTION 7.05. Reliance; Agreements; Advice of Counsel

          The Mortgagee 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 believed by it to be genuine and believed by it to be signed by the proper
party or parties. The Mortgagee may accept a copy of a resolution of the Board of Directors (or
Executive Committee thereof) of the Owner, certified by the Secretary or an

50

 

Assistant Secretary
thereof 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 the aggregate unpaid
Original Amount of Equipment Notes outstanding as of any date, the Owner may for all purposes
hereof rely on a certificate signed by any Vice President or other authorized corporate trust
officer of the Mortgagee. As to any fact or matter relating to the Owner the manner of the
ascertainment of which is not specifically described herein, the Mortgagee may for all purposes
hereof rely on an Officer’s Certificate of the Owner as to such fact or matter, and such
certificate shall constitute full protection to the Mortgagee for any action taken or omitted to be
taken by it in good faith in reliance thereon. In the administration of the trusts hereunder, the
Mortgagee may execute any of the trusts or powers hereof and perform its powers and duties
hereunder directly or through agents or attorneys and may, at the expense of the Collateral, advise
with counsel, accountants and other skilled persons to be selected and retained by it, and the
Mortgagee shall not be liable for anything done, suffered or omitted in good faith by it in
accordance with the written advice or written opinion of any such counsel, accountants or other
skilled persons.

          SECTION 7.06. Compensation

          The Mortgagee shall be entitled to reasonable compensation, including expenses and
disbursements (including the reasonable fees and expenses of counsel), for all services rendered
hereunder and shall, on and subsequent to an Event of Default hereunder, have a priority claim on
the Collateral for the payment of such compensation (other than any Unindemnified Tax), to the
extent that such compensation shall not be paid by Owner, and shall have the right, on and
subsequent to an Event of Default hereunder, to use or apply any monies held by it hereunder in the
Collateral toward such payments. The Mortgagee agrees that it shall have no right against the Note
Holders for any fee as compensation for its services as trustee under this Trust Indenture.

          SECTION 7.07. Instructions from Note Holders

          In the administration of the trusts created hereunder, the Mortgagee shall have the right to
seek instructions from a Majority in Interest of Note Holders should any provision of this Trust
Indenture appear to conflict with any other provision herein or should the Mortgagee’s duties or
obligations hereunder be unclear, and the Mortgagee shall incur no liability in refraining from
acting until it receives such instructions. The Mortgagee shall be fully protected for acting in
accordance with any instructions received under this Section 7.07.

ARTICLE IX

SUCCESSOR AND SEPARATE TRUSTEES

          SECTION 9.01. Resignation of Mortgagee; Appointment of Successor

               (a) The Mortgagee or any successor thereto may resign at any time without cause by giving at
least 30 days’ prior written notice to the Owner and each Note Holder, such resignation to be
effective upon the acceptance of the trusteeship by a successor Mortgagee. In addition, a Majority
in Interest of Note Holders may at any time (but only with the consent of Owner, which consent
shall not be unreasonably withheld, except that such consent shall not be necessary if an Event of
Default is continuing) remove the Mortgagee without cause by an instrument in writing delivered to the Owner and the Mortgagee, and the Mortgagee shall
promptly notify each Note Holder thereof in writing, such removal to be effective upon the
acceptance of the trusteeship by a successor Mortgagee. In the case of the resignation or removal
of the Mortgagee, a Majority in Interest of Note Holders may appoint a successor Mortgagee by an
instrument signed by such holders, which successor, so long as no Event of Default shall have
occurred and be continuing, shall be subject to Owner’s reasonable approval. If a successor
Mortgagee shall not have been appointed within 30 days after such notice of resignation or removal,
the Mortgagee, the Owner or any Note Holder may apply to any court of competent jurisdiction to
appoint a successor Mortgagee to act until such time, if any, as a successor shall have been
appointed as above provided. The successor Mortgagee so appointed by such court shall immediately
and without further act be superseded by any successor Mortgagee appointed as above provided.

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

               (c) Any successor Mortgagee, however appointed, shall be a bank or trust company having its
principal place of business in the continental United States and having (or whose obligations under
the Operative Agreements are guaranteed by an affiliated entity having) a combined capital and
surplus of at least $100,000,000, if there be such an institution willing, able and legally
qualified to perform the duties of the Mortgagee hereunder upon reasonable or customary terms.

               (d) Any corporation into which the Mortgagee may be merged or converted or with which it may
be consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Mortgagee shall be a party, or any corporation to which

52

 

substantially all the corporate trust
business of the Mortgagee may be transferred, shall, subject to the terms of paragraph (c) of this
Section 9.01, be a successor Mortgagee and the Mortgagee under this Trust Indenture without further
act.

               (e) The Owner consents to any change in the identity of the Mortgagee on the International
Registry occasioned by provisions of this Section 9.01, and if required by the International
Registry to reflect such change, will provide its consent thereto.

          SECTION 9.02. Appointment of Additional and Separate Trustees

               (a) Whenever (i) the Mortgagee shall deem it necessary or desirable in order to conform to any
Law of any jurisdiction in which all or any part of the Collateral shall be situated or to make any
claim or bring any suit with respect to or in connection with the Collateral, this Trust Indenture,
any other Indenture Agreement, the Equipment Notes or any of the transactions contemplated by the
Participation Agreement, (ii) the Mortgagee shall be advised by counsel satisfactory to it that it
is so necessary or prudent in the interests of the Note Holders (and the Mortgagee shall so advise
the Owner), or (iii) the Mortgagee shall have been requested to do so by a Majority in Interest of
Note Holders, then in any such case, the Mortgagee and, upon the written request of the Mortgagee,
the Owner, shall execute and deliver an indenture supplemental hereto and such other instruments as
may from time to time be necessary or advisable either (1) to constitute one or more bank or trust
companies or one or more persons approved by the Mortgagee, either to act jointly with the
Mortgagee 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 Trust Indenture as may be provided in such
supplemental indenture or other instruments as the Mortgagee or a Majority in Interest of Note
Holders may deem 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 9.02. If the Owner shall not have taken
any action requested of it under this Section 9.02(a) that is permitted or required by its terms
within 15 days after the receipt of a written request from the Mortgagee so to do, or if an Event
of Default shall have occurred and be continuing, the Mortgagee may act under the foregoing
provisions of this Section 9.02(a) without the concurrence of the Owner, and the Owner hereby
irrevocably appoints (which appointment is coupled with an interest) the Mortgagee, its agent and
attorney-in-fact to act for it under the foregoing provisions of this Section 9.02(a) in either of
such contingencies. The Mortgagee 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. In case any additional or separate trustee appointed under this Section 9.02(a) shall
die, become incapable of acting, resign or be moved, all the assets, property, rights, powers,
trusts, duties and obligations of such additional or separate trustee shall revert to the Mortgagee
until a successor additional or separate trustee is appointed as provided in this Section 9.02(a).

               (b) No additional or separate trustee shall be entitled to exercise any of the rights, powers,
duties and obligations conferred upon the Mortgagee in respect of the custody, investment and
payment of monies and all monies received by any such additional or

53

 

separate trustee from or
constituting part of the Collateral or otherwise payable under any Operative Agreement to the
Mortgagee shall be promptly paid over by it to the Mortgagee. All other rights, powers, duties and
obligations conferred or imposed upon any additional or separate trustee shall be exercised or
performed by the Mortgagee 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 the
Mortgagee 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 the Mortgagee or a Majority in Interest of Note Holders. No trustee
hereunder shall be personally liable by reason of any act or omission of any other trustee
hereunder, except that the Mortgagee shall be liable for the consequences of its lack of reasonable
care in selecting, and the Mortgagee’s own actions in acting with, any additional or separate
trustee. Each additional or separate trustee appointed pursuant to this Section 9.02 shall be
subject to, and shall have the benefit of Articles V through IX and Article XI hereof insofar as
they apply to the Mortgagee. The powers of any additional or separate trustee appointed pursuant
to this Section 9.02 shall not in any case exceed those of the Mortgagee hereunder.

               (c) If at any time the Mortgagee shall deem it no longer necessary or in order to conform to
any such Law or take any such action or shall be advised by such counsel that it is no longer so
necessary or desirable in the interest of the Note Holders, or in the event that the Mortgagee
shall have been requested to do so in writing by a Majority in Interest of Note Holders, the
Mortgagee and, upon the written request of the Mortgagee, the Owner, shall execute and deliver an
indenture supplemental hereto and all other instruments and agreements necessary or proper to
remove any additional or separate trustee. The Mortgagee may act on behalf of the Owner under this
Section 9.02(c) when and to the extent it could so act under Section 9.02(a) hereof.

such loss to be held for the account of the Mortgagee whether such payment is made to Owner (or any
Permitted Lessee) or any third party, it being understood and agreed that in the case of any
payment to Mortgagee otherwise than in respect of an Event of Loss, the Mortgagee shall, upon
receipt of evidence satisfactory to it that the damage giving rise to such payment shall have been
repaired or that such payment shall then be required to pay for repairs then being made, pay the
amount of such payment to Owner or its order, and (B) the entire amount of any loss involving
proceeds of the Threshold Amount or less or the amount of any proceeds of any loss in excess of the
Debt Balance shall be paid to Owner or its order unless an Event of Default shall have occurred and
be continuing and the insurers have been notified thereof by the Mortgagee. In the case of a loss
with respect to an engine (other than an Engine) installed on the Airframe, Mortgagee shall hold
any payment to it of any insurance proceeds in respect of such loss for the account of Owner or any
other third party that is entitled to receive such proceeds.

     2. During any period that the Aircraft is on the ground and not in operation, Owner may carry
or cause to be carried, in lieu of the insurance required by Section B.1 above, insurance otherwise
conforming with the provisions of said Section B.1 except that the scope of the risks and the type
of insurance shall be the same as from time to time applicable to aircraft owned by Owner of the
same type similarly on the ground and not in operation, provided that Owner shall maintain
insurance against risk of loss or damage to the Aircraft in an amount equal to the Debt Balance
during such period that the Aircraft is on the ground and not in operation.

C. War-Risk, Hijacking and Allied Perils Insurance

     If Owner (or any Permitted Lessee) shall at any time operate or propose to operate the
Aircraft, Airframe or any Engine (i) in any area of recognized hostilities or (ii) on international
routes and war-risk, hijacking or allied perils insurance is maintained by Owner (or any Permitted
Lessee) with respect to other aircraft owned or operated by Owner (or any Permitted Lessee) on such
routes or in such areas, Owner shall maintain or cause to be maintained war-risk, hijacking and
related perils insurance of substantially the same type carried by major United States commercial
air carriers operating the same or comparable models of aircraft on similar routes or in such areas
and in no event in an amount less than the unpaid Original Amount.

D. General Provisions

     Any policies of insurance carried in accordance with Sections A, B and C, including any
policies taken out in substitution or replacement for such policies:

     (i) in the case of Section A, shall name Mortgagee, each Note Holder, each Related
Mortgagee, each Related Note Holder and the Liquidity Provider as an additional insured
(collectively, the “Additional Insureds”), as its interests may appear;

     (ii) shall apply worldwide and have no territorial restrictions or limitations (except
only in the case of war, hijacking and related perils insurance required under

2

 

Section C, which shall apply to the fullest extent available in the international insurance market);

     (iii) shall provide that, in respect of the interests of the Additional Insureds in
such policies, the insurance shall not be invalidated or impaired by any act or omission
(including misrepresentation and nondisclosure) by Owner (or any Permitted Lessee) or any
other Person (including, without limitation, use for illegal purposes of the Aircraft or any
Engine) and shall insure the Additional Insureds regardless of any breach or violation of
any representation, warranty, declaration, term or condition contained in such policies by
Owner (or any Permitted Lessee);

     (iv) shall provide that, if the insurers cancel such insurance for any reason
whatsoever, or if the same is allowed to lapse for nonpayment of premium, or if any material
change is made in the insurance which adversely affects the interest of any of the
Additional Insureds, such cancellation, lapse or change shall not be effective as to the
Additional Insureds for 30 (seven days in the case of war risk, hijacking and allied perils
insurance) days after receipt by the Additional Insureds of written notice by such insurers
of such cancellation, lapse or change, provided that if any notice period specified
above is not reasonably obtainable, such policies shall provide for as long a period of
prior notice as shall then be reasonably obtainable;

     (v) shall waive any rights of setoff (including for unpaid premiums), recoupment,
counterclaim or other deduction, whether by attachment or otherwise, against each Additional
Insured;

     (vi) shall be primary without right of contribution from any other insurance that may
be available to any Additional Insured;

     (vii) shall provide that all of the liability insurance provisions thereof, except the
limits of liability and agreed value, shall operate in all respects as if a separate policy
had been issued covering each party insured thereunder;

     (viii) shall provide that none of the Additional Insureds shall be liable for any
insurance premium; and

     (ix) shall contain a 50/50% Clause per Lloyd’s Aviation Underwriters’ Association
Standard Policy Form AVS 103.

E. Reports and Certificates; Other Information

     On or prior to the Closing Date and on or prior to each renewal date of the insurance policies
required hereunder, Owner will furnish or cause to be furnished to Mortgagee insurance certificates describing in reasonable detail the insurance maintained by Owner hereunder and a
report, signed by Owner’s regularly retained independent insurance broker (the “Insurance Broker”),
stating the opinion of such Insurance Broker that (a) all premiums in connection with the insurance
then due have been paid and (b) such insurance complies with the terms of this Annex B, except that
such opinion shall not be required with respect to war risk insurance

3

 

provided by the FAA. To the extent such agreement is reasonably obtainable Owner will also cause the Insurance Broker to agree
to advise Mortgagee in writing of any default in the payment of any premium and of any other act or
omission on the part of Owner of which it has knowledge and which might invalidate or render
unenforceable, in whole or in part, any insurance on the Aircraft or Engines or cause the
cancellation or termination of such insurance, and to advise Mortgagee in writing at least 30 days
(seven days in the case of war-risk and allied perils coverage or such shorter period as may be
available in the international insurance market, as the case may be) prior to the cancellation,
lapse or material adverse change of any insurance maintained pursuant to this Annex B.

F. Right to Pay Premiums

     The Additional Insureds shall have the rights but not the obligations of an additional named
insured. None of Mortgagee and the other Additional Insured shall have any obligation to pay any
premium, commission, assessment or call due on any such insurance (including reinsurance).
Notwithstanding the foregoing, in the event of cancellation of any insurance due to the nonpayment
of premiums, Mortgagee shall have the option, in its sole discretion, to pay any such premium in
respect of the Aircraft that is due in respect of the coverage pursuant to this Trust Indenture and
to maintain such coverage, as Mortgagee may require, until the scheduled expiry date of such
insurance and, in such event, Owner shall, upon demand, reimburse Mortgagee for amounts so paid by
them.

G. Deductibles; Self-insurance

     Owner may self-insure with respect to the Aircraft to the same extent as it does with respect
to, or maintain policies with deductibles or premium adjustment provisions consistent with similar
provisions applicable to, other comparable aircraft operated by Owner; provided,
however, that if at any time Owner’s unsecured senior long-term debt securities are not
rated “Investment Grade”, such self-insurance shall in no case be in amounts greater than that
amount of self-insurance carried by airlines similarly situated with Owner and operating aircraft
similar to the Aircraft on similar routes; and provided further that, in the case
of public liability insurance, such self-insurance shall in no event exceed $50,000,000. The term
“Investment Grade” means a rating of “Baa3” or higher from Moody’s or a rating from any other
nationally recognized bond rating service equivalent to or better than such a rating.

contemplated by any Operative Agreement.

          (b) Owner shall promptly take such action with respect to the recording, filing, re-recording
and refiling of the Trust Indenture and any supplements thereto, including, without limitation, the

with respect to any such offer, sale or solicitation by any other party hereto, and (ii) perform
and comply with the obligations specified to be imposed on it (as a Note Holder) under each of the
Trust Indenture and the form of Equipment Note set forth in the Trust Indenture.

Holder will not sell, assign, convey, exchange or otherwise transfer any Equipment Note or any
interest in, or represented by, any Equipment Note (it being understood that this provision is not
applicable to the Pass Through Certificates) unless the proposed transferee thereof first provides
Owner with both of the following:

	 	(i)	 	a written representation and covenant that either (a) no
portion of the funds it uses to purchase, acquire and hold such Equipment Note
or interest directly or indirectly constitutes, or may be deemed under the Code
or ERISA or any rulings, regulations or court decisions thereunder to
constitute, the assets of any Plan or (b) the transfer, and subsequent holding,
of such Equipment Note or interest shall not involve or give rise to a
transaction that constitutes a prohibited transaction within the meaning of
Section 406 of ERISA or Section 4975(c)(1) of the Code involving Owner, a Pass
Through Trustee, the Subordination Agent or the proposed transferee (other than
a transaction that is exempted from the prohibitions of such sections by
applicable provisions of ERISA or the Code or administrative exemptions or
regulations issued thereunder); and

16

 

	 	(ii)	 	a written covenant that it will not transfer any Equipment Note
or any interest in, or represented by, any Equipment Note unless the subsequent
transferee also makes the representation described in clause (i) above and
agrees to comply with this clause (ii).

          6.4 Agreements

     6.4.1 Quiet Enjoyment

          Each Pass Through Trustee, Subordination Agent, each Note Holder and Mortgagee agrees as to
itself with Owner that, so long as no Event of Default shall have occurred and be continuing, such
Person shall not (and shall not permit any Affiliate or other Person claiming by, through or under
it to) interfere with Owner’s rights in accordance with the Trust Indenture to the quiet enjoyment,
possession and use of the Aircraft.

     6.4.2 Consents

          Each Pass Through Trustee, Subordination Agent and Mortgagee covenants and agrees, for the
benefit of Owner, that it shall not unreasonably withhold its consent to any consent or approval
requested of it under the terms of any of the Operative Agreements which by its terms is not to be
unreasonably withheld.

     6.4.3 Insurance

          Each Pass Through Trustee, Subordination Agent, Mortgagee and each Note Holder agrees not to
obtain or maintain insurance for its own account as permitted by Section 4.06 of the Trust
Indenture if such insurance would limit or otherwise adversely affect the coverage of any insurance
required to be obtained or maintained by Owner pursuant to Section 4.06 of the Trust Indenture.

     6.4.4 Extent of Interest of Note Holders

          A Note Holder shall not, as such, have any further interest in, or other right with respect
to, the Collateral when and if the principal and Make-Whole Amount, if any, of and interest on the
Equipment Note held by such Holder, and all other sums, then due and payable to such Holder
hereunder and under any other Operative Agreement, shall have been paid in full. The preceding
sentence shall not limit the rights of the Related Note Holders with respect to Related Secured
Obligations under the Trust Indenture, provided that a Related Note Holder shall not, as such, have
any further interest in, or other right with respect to, the Collateral when and if the Related
Secured Obligations attributable to the Related Equipment Note held by such Holder shall have been
paid in full.

     6.4.5 Foreign Registration

          Each Note Holder and Mortgagee hereby agree, for the benefit of Owner but subject to the
provisions of Section 4.02(b) of the Trust Indenture:

17

 

          (a) that Owner shall be entitled to register the Aircraft or cause the Aircraft to be
registered in a country other than the United States subject to compliance with the following:

	 	(i)	 	each of the following requirements is satisfied:

	 	(A)	 	no Special Default or Event of Default shall
have occurred and be continuing at the time of such registration;
	 
	 	(B)	 	such proposed change of registration is made in
connection with a Permitted Lease to a Permitted Air Carrier; and
	 
	 	(C)	 	such country is a country with which the United
States then maintains normal diplomatic relations or, if Taiwan, the
United States then maintains diplomatic relations at least as good as
those in effect on the Closing Date;

	 	(ii)	 	the Mortgagee shall have received an opinion of counsel
(subject to customary exceptions) reasonably satisfactory to the Mortgagee
addressed to Mortgagee as to the effect that:

	 	(A)	 	such country would recognize the Owner’s
ownership interest in the Aircraft;
	 
	 	(B)	 	after giving effect to such change in
registration, the Lien of the Trust Indenture on the Owner’s right,
title and interest in and to the Aircraft shall continue as a valid and
duly perfected first priority security interest and International
Interest and all filing, recording or other action necessary to protect
the same shall have been accomplished (or, if such opinion cannot be
given at the time of such proposed change in registration because such
change in registration is not yet effective, (1) the opinion shall
detail what filing, recording or other action is necessary and (2) the
Mortgagee shall have received a certificate from Owner 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 delivered to the Mortgagee on or prior to the effective date
of such change in registration);
	 
	 	(C)	 	unless Owner or the Permitted Air Carrier shall
have agreed to provide insurance covering the risk of requisition of
use of the Aircraft by the government of such country (so long as the
Aircraft is registered under the laws of such country), the laws of
such country require fair compensation by the government of such
country payable in currency freely convertible into Dollars and freely
removable from such country (without license or permit, unless Owner
prior to such proposed reregistration has obtained

18

 

	 	 	 	such license or permit) for the taking or requisition by such
government of such use; and

	 	(D)	 	it is not necessary, solely as a consequence of
such change in registration and without giving effect to any other
activity of the Mortgagee (or any Affiliate of the Mortgagee), for the
Mortgagee to qualify to do business in such jurisdiction as a result of
such reregistration in order to exercise any rights or remedies with
respect to the Aircraft.

          (b) In addition, as a condition precedent to any change in registration, Owner shall have
given to Mortgagee assurances reasonably satisfactory to Mortgagee:

	 	(i)	 	to the effect that the provisions of Section 4.06 of the Trust
Indenture have been complied with after giving effect to such change of
registration;
	 
	 	(ii)	 	of the payment by Owner of all reasonable out-of-pocket
expenses of each Note Holder and Mortgagee in connection with such change of
registry, including, without limitation (1) the reasonable fees and
disbursements of counsel to Mortgagee, (2) any filing or recording fees, Taxes
or similar payments incurred in connection with the change of registration of
the Aircraft and the creation and perfection of the security interest therein
in favor of Mortgagee for the benefit of Note Holders, and (3) all costs and
expenses incurred in connection with any filings necessary to continue in the
United States the perfection of the security interest in the Aircraft in favor
of Mortgagee for the benefit of Note Holders; and
	 
	 	(iii)	 	to the effect that the tax and other indemnities in favor of
each person named as an indemnitee under any other Operative Agreement afford
each such person substantially the same protection as provided prior to such
change of registration (or Owner shall have agreed upon additional indemnities
that, together with such original indemnities, in the reasonable judgment of
Mortgagee, afford such protection).

     6.4.6 Interest in Certain Engines

          Each Note Holder and Mortgagee agree, for the benefit of each of the lessor, conditional
seller, mortgagee or secured party of any airframe or engine leased to, or purchased by, Owner or
any Permitted Lessee subject to a lease, conditional sale, trust indenture or other security
agreement that it will not acquire or claim, as against such lessor, conditional seller, mortgagee
or secured party, any right, title or interest in any engine as the result of such engine being
installed on the Airframe at any time while such engine is subject to such lease, conditional sale,
trust indenture or other security agreement and owned by such lessor or conditional seller or
subject to a trust indenture or security interest in favor of such mortgagee or secured party.

22

 

Notwithstanding the foregoing, the failure of any Indemnitee to notify Owner as provided in
this Section 8.1.4, or in Section 8.1.5, shall not release Owner from any of its obligations to
indemnify such Indemnitee hereunder, except to the extent that such failure results in an
additional Expense to Owner (in which event Owner shall not be responsible for such additional
expense) or materially impairs Owner’s ability to contest such claim.

     8.1.5 Notice of Proceedings; Defense of Claims; Limitations

          (a) In case any action, suit or proceeding shall be brought against any Indemnitee for which
Owner is responsible under this Section 8.1, such Indemnitee shall notify Owner of the commencement
thereof and Owner may, at its expense, participate in and to the extent that it shall wish (subject
to the provisions of the following paragraph), assume and control the defense thereof and, subject
to Section 8.1.5(c), settle or compromise the same.

          (b) Owner or its insurer(s) shall have the right, at its or their expense, to investigate or,
if Owner or its insurer(s) shall agree not to dispute liability to the Indemnitee giving notice of
such action, suit or proceeding under this Section 8.1.5 for indemnification hereunder or under any
insurance policies pursuant to which coverage is sought, control the defense of, any action, suit
or proceeding, relating to any Expense for which indemnification is sought pursuant to this Section
8.1, and each Indemnitee shall cooperate with Owner or its insurer(s) with respect thereto;
provided, that Owner shall not be entitled to control the defense of any such action, suit,
proceeding or compromise any such Expense during the continuance of any Event of Default. In
connection with any such action, suit or proceeding being controlled by Owner, such Indemnitee
shall have the right to participate therein, at its sole cost and expense, with counsel reasonably
satisfactory to Owner; provided, that such Indemnitee’s participation does not, in the reasonable
opinion of the independent counsel appointed by the Owner or its insurers to conduct such
proceedings, interfere with the defense of such case.

          (c) In no event shall any Indemnitee enter into a settlement or other compromise with respect
to any Expense without the prior written consent of Owner, which consent shall not be unreasonably
withheld or delayed, unless such Indemnitee waives its right to be indemnified with respect to such
Expense under this Section 8.1.

          (d) In the case of any Expense indemnified by the Owner hereunder which is covered by a policy
of insurance maintained by Owner pursuant to Section 4.06 of the Indenture, at Owner’s expense,
each Indemnitee agrees to cooperate with the insurers in the exercise of their rights to
investigate, defend or compromise such Expense as may be required to retain the benefits of such
insurance with respect to such Expense.

          (e) If an Indemnitee is not a party to this Agreement, Owner may require such Indemnitee to
agree in writing to the terms of this Section 8 and Section 12.8 prior to making any payment to
such Indemnitee under this Section 8.

          (f) Nothing contained in this Section 8.1.5 shall be deemed to require an Indemnitee to
contest any Expense or to assume responsibility for or control of any judicial proceeding with
respect thereto.

23

 

     8.1.6 Information

          Owner will provide the relevant Indemnitee with such information not within the control of
such Indemnitee, as is in Owner’s control or is reasonably available to Owner, which such
Indemnitee may reasonably request and will otherwise cooperate with such Indemnitee so as to enable
such Indemnitee to fulfill its obligations under Section 8.1.5. The Indemnitee shall supply Owner
with such information not within the control of Owner, as is in such Indemnitee’s control or is
reasonably available to such Indemnitee, which Owner may reasonably request and will otherwise
cooperate with Owner so as to enable Owner to control or participate in any proceeding to the
extent permitted by Section 8.1.5 and otherwise to fulfill its obligations under Section 8.15.

     8.1.7 Effect of Other Indemnities; Subrogation; Further Assurances

          Upon the payment in full by Owner of any indemnity provided for under this Agreement, Owner,
without any further action and to the full extent permitted by Law, will be subrogated to all
rights and remedies of the person indemnified (other than with respect to any of such Indemnitee’s
insurance policies or in connection with any indemnity claim such Indemnitee may have under Section
6.03 or 8.01 of the Trust Indenture) in respect of the matter as to which such indemnity was paid.
Each Indemnitee will give such further assurances or agreements and cooperate with Owner to permit
Owner to pursue such claims, if any, to the extent reasonably requested by Owner and at Owner’s
expense.

     8.1.8 Refunds

          If an Indemnitee receives any refund, in whole or in part, with respect to any Expense paid by
Owner hereunder, it will promptly pay the amount refunded (but not an amount in excess of the
amount Owner or any of its insurers has paid in respect of such Expense) over to Owner unless an
Event of Default shall have occurred and be continuing, in which case such amounts shall be paid
over to Mortgagee to hold as security for Owner’s obligations under the Operative Agreements or, if
requested by Owner, applied to satisfy such obligations.

          8.2 Expenses

     8.2.1 Invoices and Payment

          The Mortgagee, the Applicable Pass Through Trustees and the Subordination Agent shall promptly
submit to Owner for its prompt approval (which shall not be unreasonably withheld) copies of
invoices in reasonable detail of the Transaction Expenses for which it is responsible for providing
information as they are received (but in no event later than the 90th day after the Closing Date).
If so submitted and approved, the Owner agrees promptly, but in any event no later than the 105th
day after the Closing Date, to pay Transaction Expenses.

     8.2.2 Payment of Other Expenses

          Owner shall pay (i) the ongoing fees and expenses of Mortgagee, and (ii) all reasonable
out-of-pocket costs and expenses (including the reasonable fees and disbursements of

24

 

counsel) incurred by Mortgagee or any Note Holder attributable to any waiver, amendment or
modification of any Operative Agreement to the extent requested by Owner.

          8.3 General Tax Indemnity

     8.3.1 General

          Except as provided in Section 8.3.2, Owner agrees that each payment paid by Owner under the
Equipment Notes, and any other payment or indemnity paid by Owner to a Tax Indemnitee under any
Operative Agreement, shall be free of all withholdings or deductions with respect to Taxes of any
nature (other than U.S. federal, state or local withholding taxes on, based on or measured by gross
or net income), and in the event that Owner shall be required by applicable law to make any such
withholding or deduction for any such payment (x) Owner shall make all such withholdings or
deductions, (y) the amount payable by Owner shall be increased so that after making all required
withholdings or deductions such Tax Indemnitee receives the same amount that it would have received
had no such withholdings or deductions been made, and (z) Owner shall pay the full amount withheld
or deducted to the relevant Taxing Authority in accordance with applicable law. Except as provided
in Section 8.3.2 and whether or not any of the transactions contemplated hereby are consummated,
Owner shall pay, indemnify, protect, defend and hold each Tax Indemnitee harmless from all Taxes
imposed by any Taxing Authority that may from time to time be imposed on or asserted against any
Tax Indemnitee or the Aircraft, the Airframe, any Engine or any Part or any interest in any of the
foregoing (whether or not indemnified against by any other Person), upon or with respect to the
Operative Agreements or the transactions or payments contemplated thereby, including but not
limited to any Tax imposed upon or with respect to (x) the Aircraft, the Airframe, any Engine, any
Part, any Operative Agreement (including without limitation any Equipment Notes) or any data or any
other thing delivered or to be delivered under an Operative Agreement, (y) the purchase,
manufacture, acceptance, rejection, sale, transfer of title, return, ownership, mortgaging,
delivery, transport, charter, rental, lease, re-lease, sublease, assignment, possession,
repossession, presence, use, condition, storage, preparation, maintenance, modification,
alteration, improvement, operation, registration, transfer or change of registration,
reregistration, repair, replacement, overhaul, location, control, the imposition of any Lien,
financing, refinancing requested by the Owner, abandonment or other disposition of the Aircraft,
the Airframe, any Engine, any Part, any data or any other thing delivered or to be delivered under
an Operative Agreement or (z) interest, fees or any other income, proceeds, receipts or earnings,
whether actual or deemed, arising upon, in connection with, or in respect of, any of the Operative
Agreements (including the property or income or other proceeds with respect to property held as
part of the Collateral) or the transactions contemplated thereby.

     8.3.2 Certain Exceptions

or (B) any Taxes imposed by any Taxing Authority (other than a Taxing Authority within whose
jurisdiction such Tax Indemnitee is incorporated or organized or maintains its principal place of

jurisdiction but for (I) the location, use or operation of the Aircraft, the Airframe, any Engine
or any Part thereof by an Owner Person within the jurisdiction of the Taxing Authority imposing
such Tax, or (II) the activities of any Owner Person in such jurisdiction, including, but not
limited to, use of any other aircraft by Owner in such jurisdiction, (III) the status of any Owner

          (c) on, or with respect to, or measured by, any trustee fees, commissions or compensation

disposition, or (B) a transfer pursuant to an exercise of remedies upon an Event of Default
that shall have occurred and have been continuing);

          (g) Taxes in excess of those that would have been imposed had there not been a transfer or

result of (in whole or in part) failure of such Tax Indemnitee or a related Tax Indemnitee to file

fulfill its obligations, if any, under Section 8.3.6 with respect to such return;

          (i) resulting from, or that would not have been imposed but for, any Liens arising as a result
of claims against, or acts or omissions of, or otherwise attributable to such Tax Indemnitee or a

          (j) imposed on any Tax Indemnitee as a result of the breach by such Tax Indemnitee or a
related Tax Indemnitee of any covenant of such Tax Indemnitee or any Affiliate thereof contained in
any Operative Agreement or the inaccuracy of any representation or warranty by such Tax Indemnitee
or any Affiliate thereof in any Operative Agreement;

          (k) in the nature of an intangible or similar Tax upon or with respect to the value or
principal amount of the interest of any Note Holder in any Equipment Note or the loan evidenced
thereby but only if such Taxes are in the nature of franchise Taxes or result from the Tax
Indemnitee doing business in the taxing jurisdiction and are imposed because of the place of
incorporation or the activities unrelated to the transactions contemplated by the Operative
Agreements in the taxing jurisdiction of such Tax Indemnitee;

          (l) imposed on a Tax Indemnitee by a Taxing Authority of a jurisdiction outside the United
States to the extent that such Taxes would not have been imposed but for a connection between the
Tax Indemnitee or a related Tax Indemnitee and such jurisdiction imposing such Tax unrelated to the
transactions contemplated by the Operative Agreements; or

          (m) Taxes relating to ERISA or Section 4975 of the Code.

          For purposes hereof, a Tax Indemnitee and any other Tax Indemnitees that are successors,
assigns, agents, servants or Affiliates of such Tax Indemnitee shall be related Tax Indemnitees.

     8.3.3 Payment

          (a) Owner’s indemnity obligation to a Tax Indemnitee under this Section 8.3 shall equal the
amount which, after taking into account any Tax imposed upon the receipt or accrual of the amounts
payable under this Section 8.3 and any tax benefits actually recognized by such Tax Indemnitee as a
result of the indemnifiable Tax (including, without limitation, any benefits recognized as a result
of an indemnifiable Tax being utilized by such Tax Indemnitee as

27

 

a credit against Taxes not indemnifiable under this Section 8.3), shall equal the amount of
the Tax indemnifiable under this Section 8.3.

          (b) At Owner’s request, the computation of the amount of any indemnity payment owed by Owner
or any amount owed by a Tax Indemnitee to Owner pursuant to this Section 8.3 shall be verified and
certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably
satisfactory to Owner. Such verification shall be binding. The costs of such verification
(including the fee of such public accounting firm) shall be borne by Owner unless such verification
shall result in an adjustment in Owner’s favor of 5% or more of the net present value of the
payment as computed by such Tax Indemnitee, in which case the costs shall be paid by such Tax
Indemnitee.

          (c) Each Tax Indemnitee shall provide Owner with such certifications, information and
documentation as shall be in such Tax Indemnitee’s possession and as shall be reasonably requested
by Owner to minimize any indemnity payment pursuant to this Section 8.3; provided, that
notwithstanding anything to the contrary contained herein, no Tax Indemnitee shall be required to
provide Owner with any Tax returns.

          (d) Each Tax Indemnitee shall promptly forward to Owner any written notice, bill or advice
received by it from any Taxing Authority concerning any Tax for which it seeks indemnification
under this Section 8.3. Owner shall pay any amount for which it is liable pursuant to this Section
8.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax
Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in
accordance with Section 8.3.4, within 30 days after a Final Determination (as defined below)), but
in no event more than one Business Day prior to the date the Tax to which such amount payable
hereunder relates is due. If requested by a Tax Indemnitee in writing, Owner shall furnish to the
appropriate Tax Indemnitee the original or a certified copy of a receipt for Owner’s payment of any
Tax paid by Owner or such other evidence of payment of such Tax as is acceptable to such Tax
Indemnitee. Owner shall also furnish promptly upon written request such data as any Tax Indemnitee
may reasonably require to enable such Tax Indemnitee to comply with the requirements of any taxing
jurisdiction unless such data is not reasonably available to Owner or, unless such data is
specifically requested by a Taxing Authority, is not customarily furnished by domestic air carriers
under similar circumstances. For purposes of this Section 8.3, a “Final Determination” shall mean
(i) a decision, judgment, decree or other order by any court of competent jurisdiction that occurs
pursuant to the provisions of Section 8.3.4, which decision, judgment, decree or other order has
become final and unappealable, (ii) a closing agreement or settlement agreement entered into in
accordance with Section 8.3.4 that has become binding and is not subject to further review or
appeal (absent fraud, misrepresentation, etc.), or (iii) the termination of administrative
proceedings and the expiration of the time for instituting a claim in a court proceeding.

          (e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or
indemnified by Owner pursuant to this Section 8.3 (whether such tax savings shall be by means of a
foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not
otherwise taken into account in computing such payment or indemnity such Tax Indemnitee shall pay
to Owner an amount equal to the lesser of (i) the amount of such tax savings, plus any additional
tax savings recognized as the result of any payment made pursuant

28

 

to this sentence, when, as, if, and to the extent, realized or (ii) the amount of all payments
pursuant to this Section 8.3 by Owner to such Tax Indemnitee (less any payments previously made by
such Tax Indemnitee to Owner pursuant to this Section 8.3.3 (e)) (and the excess, if any, of the
amount described in clause (i) over the amount described in clause (ii) shall be carried forward
and applied to reduce pro tanto any subsequent obligations of Owner to make payments to such Tax
Indemnitee pursuant to this Section 8.3); provided, that such Tax Indemnitee shall not be required
to make any payment pursuant to this sentence so long as a Lease Event of Default of a monetary
nature has occurred and is continuing. If a tax benefit is later disallowed or denied, the
disallowance or denial shall be treated as a Tax indemnifiable under Section 8.3.1 without regard
to the provisions of Section 8.3.2 (other than Section 8.3.2 (f)). Each such Tax Indemnitee shall
in good faith use reasonable efforts in filing its tax returns and in dealing with Taxing
Authorities to seek and claim any such tax benefit.

     8.3.4 Contest

          (a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Owner
could be liable for payment or indemnity hereunder, or if a Tax Indemnitee makes a determination
that a Tax is due for which Owner could have an indemnity obligation hereunder, such Tax Indemnitee
shall promptly give Owner notice in writing of such claim (provided, that failure to so notify
Owner shall not relieve Owner of its indemnity obligations hereunder unless such failure to notify
effectively forecloses Owner’s rights to require a contest of such claim) and shall take no action
with respect to such claim without the prior written consent of Owner for 30 days following the
receipt of such notice by Owner; provided, that, in the case of a claim made against a Tax
Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such
30-day period, such Tax Indemnitee shall, in such notice to Owner, so inform Owner, and such Tax
Indemnitee shall take no action for as long as it is legally able to do so (it being understood
that a Tax Indemnitee shall be entitled to pay the Tax claimed and sue for a refund prior to the
end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial
penalties (unless immediately reimbursed by Owner) and the act of paying the Tax would not
materially prejudice the right to contest or (B) the failure to so pay would result in criminal
penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so
paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In
addition, such Tax Indemnitee shall (provided, that Owner shall have agreed to keep such
information confidential other than to the extent necessary in order to contest the claim) furnish
Owner with copies of any requests for information from any Taxing Authority relating to such Taxes
with respect to which Owner may be required to indemnify hereunder. If requested by Owner in
writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at the expense
of Owner (including, without limitation, all reasonable costs, expenses and reasonable attorneys’
and accountants’ fees and disbursements), in good faith contest (or, if permitted by applicable
law, allow Owner to contest) through appropriate administrative and judicial proceedings the
validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying
the same except under protest if protest is necessary and proper or (III) if the payment is made,
using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or
judicial proceeding. If requested to do so by Owner, the Tax Indemnitee shall appeal any adverse
administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue
any appeals to the United States Supreme Court. If and to the extent the Tax Indemnitee is able to
separate the contested issue or issues from other

29

 

issues arising in the same administrative or judicial proceeding that are unrelated to the
transactions contemplated by the Operative Agreements without, in the good faith judgment of such
Tax Indemnitee, adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Owner to
control the conduct of any such proceeding and shall provide to Owner (at Owner’s cost and expense)
with such information or data that is in such Tax Indemnitee’s control or possession that is
reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax
Indemnitee, such Tax Indemnitee shall consult with Owner in good faith regarding the manner of
contesting such claim and shall keep Owner reasonably informed regarding the progress of such
contest. A Tax Indemnitee shall not fail to take any action expressly required by this Section
8.3.4 (including, without limitation, any action regarding any appeal of an adverse determination
with respect to any claim) and shall not settle or compromise any claim without the prior written
consent of the Owner (except as contemplated by Section 8.3.4(b) or (c)).

          (b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue
any contest (or to permit Owner to pursue any contest) unless (i) Owner shall have agreed to pay
such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in
connection with contesting such Taxes, including, without limitation, all reasonable out of pocket
costs and expenses and reasonable attorneys’ and accountants’ fees and disbursements, (ii) if such
contest shall involve the payment of the claim, Owner shall advance the amount thereof (to the
extent indemnified hereunder) plus interest, penalties and additions to tax with respect thereto
that are required to be paid prior to the commencement of such contest on an interest-free
after-Tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to the Owner any
net realized tax benefits resulting from such advance including any tax benefits resulting from
making such payment), (iii) such Tax Indemnitee shall have reasonably determined that the action to
be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless
Owner shall have made provisions to protect the interests of any such Tax Indemnitee in a manner
reasonably satisfactory to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to
notify Owner in writing promptly after it becomes aware of any such risk), (iv) no Lease Event of
Default shall have occurred and be continuing unless Owner has provided security for its
obligations hereunder by advancing to such Tax Indemnitee before proceeding or continuing with such
contest, the amount of the Tax being contested, plus any interest and penalties and an amount
estimated in good faith by such Tax Indemnitee for expenses, and (v) prior to commencing any
judicial action controlled by Owner, Owner shall have acknowledged its liability for such claim
hereunder, provided that Owner shall not be bound by its acknowledgment if the Final Determination
articulates conclusions of law and fact that demonstrate that Owner has no liability for the
contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release,
waive, compromise or settle any claim which may be indemnifiable by Owner pursuant to this Section
8.3 without the written permission of Owner, Owner’s obligation to indemnify such Tax Indemnitee
with respect to such claim (and all directly related claims and claims based on the outcome of such
claim) shall terminate and, subject to Section 8.3.4(c), such Tax Indemnitee shall repay to Owner
any amount previously paid or advanced to such Tax Indemnitee with respect to such claim, plus
interest at the rate that would have been payable by the relevant Taxing Authority with respect to
a refund of such Tax.

30

 

          (c) Notwithstanding anything contained in this Section 8.3, a Tax Indemnitee will not be
required to contest the imposition of any Tax and shall be permitted to settle or compromise any
claim without Owner’s consent if such Tax Indemnitee (i) shall waive its right to indemnity under
this Section 8.3 with respect to such Tax (and any directly related claim and any claim the outcome
of which is determined based upon the outcome of such claim), (ii) shall pay to Owner any amount
previously paid or advanced by Owner pursuant to this Section 8.3 with respect to such Tax, plus
interest at the rate that would have been payable by the relevant Taxing Authority with respect to
a refund of such Tax, and (iii) shall agree to discuss with Owner the views or positions of any
relevant Taxing Authority with respect to the imposition of such Tax.

     8.3.5 Refund

          If any Tax Indemnitee shall receive a refund of, or be entitled to a credit against other
liability for, all or any part of any Taxes paid, reimbursed or advanced by Owner, such Tax
Indemnitee shall pay to Owner within 30 days of such receipt an amount equal to the lesser of (a)
the amount of such refund or credit plus any net tax benefit (taking into account any Taxes
incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such
credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee
made pursuant to this sentence (including this clause (a)) and (b) such tax payment, reimbursement
or advance by Owner to such Tax Indemnitee theretofore made pursuant to this Section 8.3 (and the
excess, if any, of the amount described in clause (a) over the amount described in clause (b) shall
be carried forward and applied to reduce pro tanto any subsequent obligation of Owner to make
payments to such Tax Indemnitee pursuant to this Section 8.3). If, in addition to such refund or
credit, such Tax Indemnitee shall receive (or be credited with) an amount representing interest on
the amount of such refund or credit, such Tax Indemnitee shall pay to Owner within 30 days of such
receipt or realization of such credit that proportion of such interest that shall be fairly
attributable to Taxes paid, reimbursed or advanced by Owner prior to the receipt of such refund or
realization of such credit.

     8.3.6 Tax Filing

          If any report, return or statement is required to be filed with respect to any Tax which is
subject to indemnification under this Section 8.3, Owner shall timely file the same (except for any
such report, return or statement which a Tax Indemnitee has timely notified the Owner in writing
that such Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to
file, in its own name); provided, that the relevant Tax Indemnitee shall furnish Owner with any
information in such Tax Indemnitee’s possession or control that is reasonably necessary to file any
such return, report or statement and is reasonably requested in writing by Owner (it being
understood that the Tax Indemnitee shall not be required to furnish copies of its actual tax
returns, although it may be required to furnish relevant information contained therein). Owner
shall either file such report, return or statement and send a copy of such report, return or
statement to such Tax Indemnitee, or, where Owner is not permitted to file such report, return or
statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such
report, return or statement to such Tax Indemnitee in a manner satisfactory to such Tax Indemnitee
within a reasonable time prior to the time such report, return or statement is to be filed.

31

 

     8.3.7 Forms

          Each Tax Indemnitee agrees to furnish from time to time to Owner or Mortgagee or to such other
person as Owner or Mortgagee may designate, at Owner’s or Mortgagee’s request, such duly executed
and properly completed forms as may be necessary or appropriate in order to claim any reduction of
or exemption from any withholding or other Tax imposed by any Taxing Authority, if (x) such
reduction or exemption is available to such Tax Indemnitee and (y) Owner has provided such Tax
Indemnitee with any information necessary to complete such form not otherwise reasonably available
to such Tax Indemnitee.

     8.3.8 Non-Parties

          If a Tax Indemnitee is not a party to this Agreement, Owner may require the Tax Indemnitee to
agree in writing, in a form reasonably acceptable to Owner, to the terms of this Section 8.3 and
Section 12.8 prior to making any payment to such Tax Indemnitee under this Section 8.3.

     8.3.9 Subrogation

          Upon payment of any Tax by Owner pursuant to this Section 8.3 to or on behalf of a Tax
Indemnitee, Owner, without any further action, shall be subrogated to any claims that such Tax
Indemnitee may have relating thereto. Such Tax Indemnitee shall cooperate with Owner (to the
extent such cooperation does not result in any unreimbursed cost, expense or liability to such Tax
Indemnitee) to permit Owner to pursue such claims.

          8.4 Payments

          Any payments made pursuant to Section 8.1 or 8.3 shall be due on the 60th day after demand
therefor and shall be made directly to the relevant Indemnitee or Tax Indemnitee or to Owner, in
immediately available funds at such bank or to such account as specified by such Indemnitee or Tax
Indemnitee or Owner, as the case may be, in written directives to the payor, or, if no such
direction shall have been given, by check of the payor payable to the order of, and mailed to, such
Indemnitee or Tax Indemnitee or Owner, as the case may be, by certified mail, postage prepaid, at
its address as set forth in this Agreement.

          8.5 Interest

          If any amount, payable by Owner, any Indemnitee or any Tax Indemnitee under Section 8.1 or 8.3
is not paid when due, the person obligated to make such payment shall pay on demand, to the extent
permitted by Law, to the person entitled thereto, interest on any such amount for the period from
and including the due date for such amount to but excluding the date the same is paid, at the
Payment Due Rate. Such interest shall be paid in the same manner as the unpaid amount in respect
of which such interest is due.

          8.6 Benefit of Indemnities

          The obligations of Owner in respect of all indemnities, obligations, adjustments and payments
in Section 8.1 or 8.3 are expressly made for the benefit of, and shall be enforceable

32

 

by, the Indemnitee or Tax Indemnitee entitled thereto, notwithstanding any provision of the
Trust Indenture.

SECTION 9. ASSIGNMENT OR TRANSFER OF INTEREST

          9.1 Note Holders

          Subject to Section 6.3.2 hereof and Section 2.07 of the Trust Indenture, any Note Holder may,
at any time and from time to time, Transfer or grant participations in all or any portion of the
Equipment Notes and/or all or any portion of its beneficial interest in its Equipment Notes to any
person (it being understood that the sale or issuance of Pass Through Certificates by a Pass
Through Trustee shall not be considered a Transfer or participation); provided, that any
participant in any such participations shall not have any direct rights under the Operative
Agreements or any Lien on all or any part of the Aircraft or the Collateral and Owner shall not
have any increased liability or obligations as a result of any such participation. In the case of
any such Transfer, the Transferee, by acceptance of Equipment Notes in connection with such
Transfer, shall be deemed to be bound by (i) all of the covenants of Note Holders contained in the
Operative Agreements and (ii) certain terms of the Intercreditor Agreement as specified in such
Equipment Notes and/or Section 2.07 of the Trust Indenture.

          9.2 Effect of Transfer

          Upon any Transfer in accordance with Section 9.1 (other than any Transfer by any Note Holder,
to the extent it only grants participations in Equipment Notes or in its beneficial interest
therein), Transferee shall be deemed a “Note Holder,” for all purposes of this Agreement and the
other Operative Agreements, and the transferring Note Holder shall be released from all of its
liabilities and obligations under this Agreement and any other Operative Agreements to the extent
such liabilities and obligations arise after such Transfer and, in each case, to the extent such
liabilities and obligations are assumed by the Transferee; provided, that such transferring Note
Holder (and its respective Affiliates, successors, assigns, agents, servants, representatives,
directors and officers) will continue to have the benefit of any rights or indemnities under any
Operative Agreement vested or relating to circumstances, conditions, acts or events prior to such
Transfer.

SECTION 10. SECTION 1110

          It is the intention of each of the Owner, the Note Holders (such intention being evidenced by
each of their acceptance of an Equipment Note), and Mortgagee that Mortgagee shall be entitled to
the benefits of Section 1110 in the event of a case under Chapter 11 of the Bankruptcy Code in
which Owner is a debtor.

SECTION 11. CHANGE OF CITIZENSHIP

          11.1 Generally

          Without prejudice to the representations, warranties or covenants regarding the status of any
party hereto as a Citizen of the United States, each of Owner, WTC and Mortgagee agrees that it
will, immediately upon obtaining knowledge of any facts that would cast doubt

33

 

upon its continuing status as a Citizen of the United States and promptly upon public
disclosure of negotiations in respect of any transaction which would or might adversely affect such
status, notify in writing all parties hereto of all relevant matters in connection therewith.

          11.2 Mortgagee

          Upon WTC giving any notice in accordance with Section 11.1, Mortgagee shall (if and so long as
such citizenship is necessary under the Act as in effect at such time or, if it is not necessary,
if and so long as Mortgagee’s citizenship could have any adverse effect on Owner or any Note
Holder), subject to Section 9.02 of the Trust Indenture, resign as Mortgagee promptly upon its
ceasing to be such a citizen.

SECTION 12. MISCELLANEOUS

          12.1 Amendments

          No provision of this Agreement may be amended, supplemented, waived, modified, discharged,
terminated or otherwise varied orally, but only by an instrument in writing that specifically
identifies the provision of this Agreement that it purports to amend, supplement, waive, modify,
discharge, terminate or otherwise vary and is signed by the party against which the enforcement of
the amendment, supplement, waiver, modification, discharge, termination or variance is sought.
Each such amendment, supplement, waiver, modification, discharge, termination or variance shall be
effective only in the specific instance and for the specific purpose for which it is given. No
provision of this Agreement shall be varied or contradicted by oral communication, course of
dealing or performance or other manner not set forth in an agreement, document or instrument in
writing and signed by the party against which enforcement of the same is sought.

          12.2 Severability

          If any provision hereof shall be held invalid, illegal or unenforceable in any respect in any
jurisdiction, then, to the extent permitted by Law, (a) all other provisions hereof shall remain in
full force and effect in such jurisdiction and (b) such invalidity, illegality or unenforceability
shall not affect the validity, legality or enforceability of such provision in any other
jurisdiction. If, however, any Law pursuant to which such provisions are held invalid, illegal or
unenforceable may be waived, such Law is hereby waived by the parties hereto to the full extent
permitted, to the end that this Agreement shall be deemed to be a valid and binding agreement in
all respects, enforceable in accordance with its terms.

          12.3 Survival

          The indemnities set forth herein shall survive the delivery or return of the Aircraft, the
Transfer of any interest by any Note Holder of its Equipment Note and the expiration or other
termination of this Agreement or any other Operative Agreement.

34

 

          12.4 Reproduction of Documents

          This Agreement, all schedules and exhibits hereto and all agreements, instruments and
documents relating hereto, including, without limitation, (a) consents, waivers and modifications
that may hereafter be executed and (b) financial statements, certificates and other information
previously or hereafter furnished to any party hereto, may be reproduced by such party by any
photographic, photostatic, microfilm, micro-card, miniature photographic or other similar process,
and such party may destroy any original documents so reproduced. To the extent permitted by law,
any such reproduction shall be as admissible in evidence as the original itself in any judicial or
administrative proceeding (whether or not the original is in existence and whether or not such
reproduction was made by such party in the regular course of business) and any enlargement,
facsimile or further reproduction of such reproduction likewise is admissible in evidence.

          12.5 Counterparts

          This Agreement and any amendments, waivers, consents or supplements hereto may be executed in
any number of counterparts (or upon separate signature pages bound together into one or more
counterparts), each of which when so executed shall be deemed to be an original, and all of which
counterparts, taken together, shall constitute one and the same instrument.

          12.6 No Waiver

          No failure on the part of any party hereto to exercise, and no delay by any party hereto in
exercising, any of its rights, powers, remedies or privileges under this Agreement or provided at
Law, in equity or otherwise shall impair, prejudice or constitute a waiver of any such right,
power, remedy or privilege or be construed as a waiver of any breach hereof or default hereunder or
as an acquiescence therein nor shall any single or partial exercise of any such right, power,
remedy or privilege preclude any other or further exercise thereof by it or the exercise of any
other right, power, remedy or privilege by it. No notice to or demand on any party hereto in any
case shall, unless otherwise required under this Agreement, entitle such party to any other or
further notice or demand in similar or other circumstances or constitute a waiver of the rights of
any party hereto to any other or further action in any circumstances without notice or demand.

          12.7 Notices

          Unless otherwise expressly permitted by the terms hereof, all notices, requests, demands,
authorizations, directions, consents, waivers and other communications required or permitted to be
made, given, furnished or filed hereunder shall be in writing in the English language (it being
understood that the specification of a writing in certain instances and not in others does not
imply an intention that a writing is not required as to the latter), shall refer specifically to
