[Reg. No.]

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

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

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

constituting part of the Collateral, for distribution by Loan Trustee pursuant to this
Indenture.

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

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

     For purposes hereof, the term “Indenture” means the Indenture and Security Agreement ([Reg.
No.]), dated as of _________ ___, 20__, between Company and U.S. Bank Trust National Association,
as Loan Trustee (“Loan Trustee”), as the same may be amended, supplemented or otherwise

Equipment Note and not defined herein, unless the context otherwise requires, shall have the
respective meanings set forth or incorporated by reference, and shall be construed and interpreted
in the manner described, in the Indenture.

     This Equipment Note shall bear interest, payable on demand, at the Past Due Rate (and not the
Debt Rate) (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any
principal amount and (to the extent permitted by applicable law) Make-Whole Amount, if any,
interest, and any other amounts payable hereunder not paid when due for any period during which the
same is overdue, in each case for the period the same is overdue. Amounts shall be overdue if not
paid in the manner provided herein or in the Indenture 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 Loan Trustee, or at the office of
any successor trustee, in the manner provided in Section 2.07 of the Indenture.

     The principal amount and interest and other amounts due hereunder shall be payable in Dollars
in immediately available funds at the Corporate Trust Office of Loan Trustee, or as otherwise
provided in the Indenture. Company shall not have any responsibility for the distribution of any
such payment to Noteholder of this Equipment Note. Each such payment shall be made on the date
such payment is due and without any presentment or surrender of this Equipment Note, except that in
the case of any final payment with respect to this Equipment Note, the Equipment Note shall be
surrendered to Loan Trustee for cancellation.

     The holder hereof, by its acceptance of this Equipment Note, agrees that, except as provided
in the Indenture, including the subordination provisions referred to below, each payment of an
installment of principal amount, Make-Whole Amount, if any, and

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

12

 

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 (i) any overdue principal
amount, and (ii) to the extent permitted by law, any overdue Make-Whole Amount, if any, any
overdue interest and any other overdue amounts hereunder) to the date of such payment;
second, to the payment of Make-Whole Amount, if any, with respect to this Equipment Note;
third, to the payment of the principal amount of this Equipment Note (or portion thereof)
then due hereunder, if any; and fourth, the balance, if any, remaining thereafter to the
payment of installments of the principal amount of this Equipment Note (or portion thereof)
remaining unpaid in the inverse order of their maturity.

     This Equipment Note is one of the Equipment Notes referred to in the Indenture which have been
or are to be issued by Company pursuant to the terms of the Indenture. The Collateral is held by
Loan Trustee as security, in part, for the Equipment Notes. The provisions of this Equipment Note
are subject to the Indenture, the Related Indentures, the Participation Agreement, the other
Operative Documents and the Pass Through Documents. Reference is hereby made to the Indenture, the

     Section 2.02 Issuance and Terms of Equipment Notes. The Equipment Notes shall be
dated the date of issuance thereof, shall be issued in (a) separate Series consisting of
Series A Equipment Notes and Series B Equipment Notes and (b) the maturities and principal
amounts and shall bear interest at the applicable Debt Rates specified in Schedule I (as, in the
case of any new Series B Equipment Notes issued after the Closing Date pursuant to the provisions
of this Section 2.02 and Section 2.11(b), such Schedule I may be amended in connection with such
issuance). On the Closing Date, each Series A Equipment Note and Series B Equipment Note shall be
issued to Subordination Agent on behalf of each of Pass Through Trustees for the applicable Pass
Through Trust created under the Pass Through Trust Agreements referred to in Schedule II. If all
of the Series B Equipment Notes shall have been redeemed pursuant to Section 2.11(b), and if,
simultaneously with such redemption, new Series B Equipment Notes, which may have terms different
from those of the redeemed Series B Equipment Notes, are being issued, Company shall, subject to
compliance with the conditions set forth in Section 4(a)(v) of the Note Purchase Agreement, Section
2.02 of the Participation Agreement and Section 8.01(c) of the Intercreditor Agreement, issue new
Series B Equipment Notes with the same Series B designation as, but with the terms that may differ
from those of, the redeemed Series B Equipment Notes. Any new Series B Equipment Notes issued
after the Closing Date pursuant to the immediately preceding sentence shall have such maturities,
principal amounts and interest rate as specified in Schedule I hereto in respect of Series B
Equipment Notes, as amended in connection with any such issuance. The Equipment Notes shall be
issued in registered form only. The Equipment Notes shall be

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

16

 

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 may be issued pursuant to the provisions
of Section 2.11(b).

     Each Equipment Note shall bear interest at the Debt Rate specified for the applicable Series
(calculated on the basis of a year of 360 days comprised of twelve 30-day months), payable in
arrears on each Payment Date on the unpaid principal amount thereof from time to time outstanding
from the most recent Payment Date to which interest has been paid or duly provided for (or, if no
interest has been so paid or provided for, from the date of issuance of such Equipment Note) until
such principal amount is paid in full, as further provided in the form of Equipment Note set forth
in Section 2.01. The principal amount of each Series A Equipment Note and each Series B Equipment
Note shall be payable in installments or in a single payment on the Payment Dates set forth in such
Equipment Note, each such installment, if any, to be in an amount computed by multiplying the
original principal amount of such Equipment Note by the corresponding percentage set forth in
Schedule I hereto (as, in the case of any new Series B Equipment Notes issued after the Closing
Date pursuant to the provisions of this Section 2.02 and Section 2.11(b), such Schedule I may be
amended in connection with such issuance) applicable to such Series, the applicable portion of
which shall be attached as Schedule I to such Equipment Note, opposite the Payment Date on which
such installment is due. Notwithstanding the foregoing, the final payment made under each
Equipment Note shall be in an amount sufficient to discharge in full the unpaid principal amount
and all accrued and unpaid interest on, and any other amounts due under, such Equipment Note. Each
Equipment Note shall bear interest, payable on demand, at the Past Due Rate (and not at the Debt
Rate) (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any
principal amount and (to the extent permitted by applicable law) Make-Whole Amount, if any,
interest and any other amounts payable thereunder not paid when due for any period during which the
same is overdue, in each case for the period the same is overdue. Amounts shall be overdue under
an Equipment Note if not paid in the manner provided herein when due (whether at stated maturity,
by acceleration or otherwise). Notwithstanding anything to the contrary contained herein, if any
date on which a payment hereunder or under any Equipment Note becomes due and payable is not a
Business Day, then such payment shall not be made on such scheduled date but shall be made on the
next succeeding Business Day with the same force and effect as if made on such scheduled date, and
if such payment is made on such next succeeding Business Day, no interest shall accrue on the
amount of such payment from and after such scheduled date.

     The Equipment Notes shall be executed on behalf of Company by the manual or facsimile
signature of one of its authorized officers. Equipment Notes bearing the

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

17

 

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

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

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

18

 

payment in respect of any Equipment Note, such Equipment Note shall be surrendered to Loan
Trustee for cancellation. Notwithstanding any other provision of this Indenture to the contrary,
Loan Trustee shall not be required to make, or cause to be made, wire transfers as aforesaid prior
to the first Business Day on which it is practicable for Loan Trustee to do so in view of the time
of day when the funds to be so transferred were received by it if such funds were received after
1:00 p.m. (New York City time) at the place of payment, in which case Loan Trustee shall make such
required payment on the next succeeding Business Day. So long as any signatory to the
Participation Agreement or nominee thereof shall be a registered Noteholder, all payments to it
shall be made to the account of such Noteholder specified in Schedule I to the Participation
Agreement and otherwise in the manner provided in or pursuant to the Participation Agreement unless
it shall have specified some other account or manner of payment by notice to Loan Trustee
consistent with this Section 2.03.

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

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

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

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

19

 

     second, to the payment of Make-Whole Amount, if any, with respect to such
Equipment Note;

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

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

     Section 2.06 Termination of Interest in Collateral. No Noteholder or Indenture
Indemnitee shall, as such, have any further interest in, or other right with respect to, the
Collateral when and if the principal amount of, Make-Whole Amount, if any, and interest (including,
to the extent permitted by applicable law, post-petition interest and interest on any overdue
amounts) on and all other amounts due under all Equipment Notes held by such Noteholder and all
other sums then due and payable to such Noteholder or Indenture Indemnitee, as the case may be,
hereunder (including, without limitation, under Section 2.14) and under the Participation Agreement
by Company (the “Secured Obligations”) have been paid in full.

     Subject to Section 10.01 hereof, no Related Indenture Indemnitee shall, as such, have any
further interest in, or other right with respect to, the Collateral when and if all Related Secured
Obligations have been paid in full.

     Section 2.07 Registration, Transfer and Exchange of Equipment Notes. Loan Trustee
shall keep a register or registers (the “Equipment Note Register”) in which Loan Trustee
shall provide for the registration of Equipment Notes and the registration of transfers of
Equipment Notes. No such transfer shall be given effect unless and until registration hereunder
shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of
Loan Trustee. Loan Trustee is hereby appointed “Equipment Note Registrar” for the purpose of
registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any
Equipment Note intending to exchange or transfer such Equipment Note shall surrender such Equipment
Note to Loan Trustee at the Corporate Trust Office, together with a written request from the
registered holder thereof for the issuance of a new Equipment Note of the same Series, specifying,
in the case of a surrender for transfer, the name and address of the new holder or holders. Upon
surrender for registration of transfer of any Equipment Note and subject to satisfaction of Section
2.09, Company shall execute, and Loan Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

20

 

Equipment Notes of an equal aggregate principal amount and of the same Series. At the option
of Noteholder, Equipment Notes may be exchanged for other Equipment Notes of the same Series of any
authorized denominations of an equal aggregate principal amount, upon surrender of the Equipment
Notes to be exchanged to Loan Trustee at the Corporate Trust Office. Whenever any Equipment Notes
are so surrendered for exchange, Company shall execute, and Loan Trustee shall authenticate and
deliver, the Equipment Notes which Noteholder making the exchange is entitled to receive. All
Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether
under this Section 2.07 or under Section 2.08 or otherwise under this Indenture) shall be the valid
obligations of Company evidencing the same respective obligations, and entitled to the same
security and benefits under this Indenture, as the Equipment Notes surrendered upon such
registration of transfer or exchange. Every Equipment Note presented or surrendered for
registration of transfer shall (if so required by Company or Loan Trustee) be duly endorsed or be
accompanied by a written instrument of transfer in form satisfactory to Loan Trustee, duly executed
by Noteholder or such Noteholder’s attorney duly authorized in writing, and Company and Loan
Trustee shall require evidence satisfactory to it as to the compliance of any such transfer with
the Securities Act and the securities laws of any applicable state or jurisdiction. Loan Trustee
shall make a notation on each new Equipment Note of the amount of all payments of principal amount
previously made on the old Equipment Note or Equipment Notes with respect to which such new
Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment
Notes has been paid. Principal, interest and all other amounts shall be deemed to have been paid
on such new Equipment Note to the date on which such amounts have been paid on such old Equipment
Note. Company shall not be required to exchange any surrendered Equipment Notes as provided above
(a) during the ten-day period preceding the due date of any payment on such Equipment Note
or (b) that has been called for redemption. Company and Loan Trustee shall in all cases
deem and treat the Person in whose name any Equipment Note has been issued and registered on the
Equipment Note Register as the absolute owner and Noteholder of such Equipment Note for the purpose
of receiving payment of all amounts payable with respect to such Equipment Note and for all other
purposes, and neither Company nor Loan Trustee shall be affected by any notice to the contrary.
Loan Trustee will promptly notify Company of each registration of a transfer of an Equipment Note.
Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, agrees to the
provisions of the Indenture, the Related Indentures, the Participation Agreement, the other
Operative Documents and the Pass Through Documents applicable to Noteholders or, in the case of
each Related Indenture, Related Noteholders, and, without limiting the generality of the foregoing,
any such transferee of an Equipment Note, by its acceptance of an Equipment Note: (i)
agrees to the applicable provisions of Sections 6.01, 7.10 and 7.11 of the Participation Agreement,
and shall be deemed to have represented, warranted and covenanted to the parties to the
Participation Agreement as to the matters represented, warranted and covenanted by Noteholders,
including Pass Through Trustees, in the Participation Agreement and (ii) agrees to the
restrictions set forth in Sections 4.01(a)(ii)

 Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

21

 

and 4.01(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 to, or otherwise authorize, Loan
Trustee to take any action that would violate Sections 4.01(a)(ii) or 4.01(a)(iii) of the
Intercreditor Agreement. Subject to compliance by Noteholder and any transferee of the
requirements set forth in this Section 2.07 and in Section 2.09, Loan Trustee and Company shall use
all reasonable efforts to issue new Equipment Notes upon transfer or exchange within ten 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 becomes mutilated, destroyed, lost or stolen, Company shall, upon the written request of the
holder of such Equipment Note and subject to satisfaction of this Section 2.08 and of Section 2.09,
execute and Loan Trustee shall authenticate and deliver in replacement thereof a new Equipment Note
of the same Series, payable in the same principal 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 Loan Trustee, and a photocopy thereof shall be
furnished to Company. If the Equipment Note being replaced has been destroyed, lost or stolen, the
holder of such Equipment Note shall furnish to Company and Loan Trustee such security or indemnity
as may be required by them to save Company and Loan Trustee harmless and evidence satisfactory to
Company and Loan Trustee of the destruction, loss or theft of such Equipment Note and of the
ownership thereof.

     Section 2.09 Payment of Expenses on Transfer; Cancellation.

     (a) No service charge shall be made to a Noteholder for any registration of transfer or
exchange of Equipment Notes, but Loan Trustee, 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) Loan Trustee shall cancel all Equipment Notes surrendered for replacement, redemption,
transfer, exchange, payment or cancellation, shall keep a copy of such canceled Equipment Notes,
and shall send the original canceled Equipment Notes marked “canceled” to Company.

     Section 2.10 Mandatory Redemption of Equipment Notes. Company shall redeem the
Equipment Notes in whole in connection with an Event of Loss in respect of the Airframe or the
Airframe and the Engines installed thereon (unless Company has

performed the option set forth in Section 7.05(a)(i) with respect thereto) on or before the
Loss Payment Date at a redemption price equal to 100% of the unpaid principal amount thereof,
together with all accrued and unpaid interest thereon to (but excluding) the date of redemption and
all other Secured Obligations owed or then due and payable to Noteholders, but without any
Make-Whole Amount.

     Section 2.11 Voluntary Redemption of Equipment Notes.

     (a) Except as provided in Section 2.11(b), all (but not less than all) of the Equipment Notes
may be redeemed by Company at any time upon at least 30 days’ revocable prior written notice to
Loan Trustee and Noteholders, and such Equipment Notes shall be redeemed in whole at a redemption
price equal to 100% of the unpaid principal amount thereof, together with accrued and unpaid
interest thereon to (but excluding) the date of redemption and all other Secured Obligations owed
or then due and payable to Noteholders, plus Make-Whole Amount, if any; provided that no
redemption shall be permitted under this Section 2.11(a) unless, simultaneously with such
redemption, the Related Equipment Notes shall also be redeemed.

     (b) All of the Series B Equipment Notes may be redeemed by Company upon at least 30 days’
revocable prior written notice to Loan Trustee and Noteholders of the Series B Equipment Notes, and
the Series B Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the
unpaid principal amount thereof, together with accrued and unpaid interest thereon to (but
excluding) the date of redemption and all other Secured Obligations owed or then due and payable to
Noteholders of the Series B Equipment Notes, plus Make-Whole Amount, if any; provided that:

     (i) no redemption shall be permitted under this Section 2.11(b) unless, simultaneously
with such redemption, the Related Series B Equipment Notes shall also be redeemed; and

     (ii) if, simultaneously with such redemption, new Series B Equipment Notes, which may
have terms different from those of the redeemed Series B Equipment Notes, are being issued,
such new Series B Equipment Notes shall be issued in accordance with Section 2.02 of the
Participation Agreement, Section 4(a)(v) of the Note Purchase Agreement and Section 8.01(c)
of the Intercreditor Agreement.

     (c) Notwithstanding anything to the contrary in Section 2.11(a) or (b), so long as
Company or any of its Affiliates beneficially owns 100% of the Pass Through Certificates issued by
any Pass Through Trustee, the redemption price shall not include, and no Noteholder shall have any
right to otherwise claim, any Make-Whole Amount with respect to the Series of Equipment Notes
issued to Subordination Agent for the benefit of such Pass Through Trustee.

     Section 2.12 Redemptions; Notice of Redemptions; Repurchases.

     (a) No redemption of any Equipment Note may be made except to the extent and in the manner
expressly permitted by this Indenture. Company may at any time repurchase any of the Equipment
Notes not held by Subordination Agent at any price and may hold or resell such Equipment Notes or
surrender such Equipment Notes to Loan Trustee for cancellation.

     (b) Notice of redemption with respect to the Equipment Notes shall be given by Loan Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the
applicable redemption date, to each Noteholder of such Equipment Notes to be redeemed, at such
Noteholder’s address appearing in the Equipment Note Register; provided that such notice
shall be revocable by written notice from Company to Loan Trustee given no later than three days
prior to the redemption date. All notices of redemption shall state: (1) the redemption

     (c) On or before the redemption date, Company (or any person on behalf of Company) shall, to
the extent an amount equal to the redemption price for the Equipment Notes to be redeemed on the
redemption date shall not then be held by Loan Trustee, deposit or cause to be deposited with Loan
Trustee by 10:00 a.m. (New York City time) on the redemption date in immediately available funds

Upon surrender of any such Equipment Note for redemption in accordance with said notice, such
Equipment Note shall be redeemed at the redemption price.

     Section 2.13 Subordination.

     (a) The indebtedness evidenced by the Series B Equipment Notes is, to the extent and in the
manner provided in this Indenture (as, in the case of any new Series B Equipment Notes issued after
the Closing Date pursuant to the provisions of Sections 2.02 and 2.11(b), may be amended in
connection with the issuance of such new Series B Equipment Notes), subordinate and subject in
right of payment to the prior payment in full of the Secured Obligations in respect of the Series A
Equipment Notes, and the Series B Equipment Notes are issued subject to such provisions. The
indebtedness evidenced by the Series A Equipment Notes and the Series B Equipment Notes is, to the

payment to the prior payment in full under such Related Indenture of the “Secured Obligations” in
respect of the “Equipment Notes” issued under such Related Indenture, and the Series A Equipment

Equipment Notes of any Series, each Noteholder of such Series (i) agrees to and shall be
bound by such provisions, (ii) authorizes and directs Loan Trustee or the Related Loan
Trustee under the applicable Related Indenture, as appropriate, on such Noteholder’s behalf to take
any action necessary or appropriate to effectuate the subordination as provided in this Indenture
and the applicable Related Indenture and (iii) appoints Loan Trustee or the Related Loan
Trustee under the applicable Related Indenture, as appropriate, as such Noteholder’s
attorney-in-fact for such purpose.

     (b) Company, Loan Trustee and, by acceptance of its Equipment Notes of any Series, each

its capacity as Loan Trustee, U.S. Bank waives any claim or lien against any Eligible Account it
may have, by operation of law or otherwise, for any amount owed to it by Company. The Securities
Intermediary hereby agrees that, notwithstanding anything to the contrary in this Indenture,
(i) any amounts to be held by Loan Trustee pursuant to paragraph (vii) of clause “third” of
Section 3.03 and any investment earnings thereon or other Permitted Investments in which such
amounts are invested will be credited to an Eligible Account (the “Securities Account”) for
which it is a “securities intermediary” (as defined in Section 8-102(a)(14) of the NY UCC) and Loan
Trustee is the “entitlement holder” (as defined in Section 8-102(a)(7) of the NY UCC) of the
“security 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

Investments, other investments, securities, instruments or other property) credited to the
Securities Account will be treated as a “financial asset” under Article 8 of the NY UCC,
(iv) its “securities intermediary’s jurisdiction” (as defined in Section 8-110(e) of the NY
UCC) with respect to the Securities Account is the State of New York, and (v) all
securities, instruments and other property in order or registered form and credited to the
Securities Account shall be payable to or to the order of, or registered in the name of, the
Securities Intermediary or shall be indorsed to the Securities Intermediary or in blank, and in no
case whatsoever shall any financial asset credited to the Securities Account be registered in the
name of Company, payable to or to the order of Company or specially indorsed to Company except to
the extent the foregoing have been specially endorsed by Company to the Securities Intermediary or
in blank. Loan Trustee agrees that it will hold (and will indicate clearly in its books and
records that it holds) its “security entitlements” to the “financial assets” credited to the
Securities Account in trust for the benefit of Noteholders, each Indenture Indemnitee and each

of Loan Trustee being the “entitlement holder” in respect of the Securities Account as provided

Indenture, to give all “entitlement orders” (as defined in Section 8-102(a)(8) of the NY UCC) with
respect to the Securities Account and any and all financial assets and other property credited

against the Securities Account or any financial asset carried therein, U.S. Bank will promptly
notify Loan Trustee and Company thereof.

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

     (d) Company fails to perform or observe any other covenant, condition or agreement to
be performed or observed by it under any Operative Document, and such failure continues
unremedied for a period of 60 days after receipt by Company of written notice thereof from

remedied, no such failure shall constitute an Event of Default for a period of one year
after such notice is received by Company so long as Company is diligently proceeding to
remedy such failure;

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

     (f) Company consents to the appointment of or the taking of possession by a receiver,

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

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

     (ii) (A) cause Company, upon the demand by notice of Loan Trustee, at
Company’s expense, to deliver promptly, and Company shall deliver promptly, all or such
part of the Airframe or any Engine as Loan Trustee so demands to Loan Trustee or its order,
or, if Company has failed to so deliver the Airframe or any Engine after such demand, Loan
Trustee, at its option, may enter upon the premises where all or any part of the Airframe
or any Engine are located and take immediate possession of and remove the same together
with any engine which is not an Engine but which is installed on the Airframe, subject to
all of the rights of the owner, lessor, lienor or secured party of such engine;
provided that the Airframe with an engine (which is not an Engine) installed
thereon may be flown or returned only to a location within the continental United States,
and such engine shall be held at the expense of Company for the account of any such

owner,
lessor, lienor, secured party or, if such engine is owned by Company, may
at the option of Company with the consent of Loan Trustee (which will not be
unreasonably withheld) or at the option of Loan Trustee with the consent of Company (which
will not be unreasonably withheld), be exchanged with Company for an Engine in accordance
with the provisions of Section 7.05(b); (B) sell all or any part of the Airframe
and any Engine at public or private sale, whether or not Loan Trustee at the time has
possession thereof, as Loan Trustee may determine, or otherwise dispose of, hold, use,
operate, lease to others or keep idle all or any part of the Airframe or such Engine as
Loan Trustee, in its sole discretion, determines, all free and clear of any rights or
claims of Company, and the proceeds of such sale or disposition shall be applied as set
forth in Section 3.03; or (C) exercise any other remedy of a secured party under
the Uniform Commercial Code of the State of New York (whether or not in effect in the
jurisdiction in which enforcement is sought); provided that, notwithstanding
anything to the contrary set forth herein or in any other Operative Document, (i)
as permitted by Article 15 of the Cape Town Convention, the provisions of Chapter III of
the Cape Town Convention are hereby excluded and made inapplicable to this Indenture and
the other Operative Documents, except for those provisions of such Chapter III that cannot
be derogated from; and (ii) as permitted by Article IV(3) of the Aircraft Protocol,
the provisions of Chapter II of the Aircraft Protocol are hereby excluded and made
inapplicable to this Indenture and the other Operative Documents, except for (x)
Article XVI of the Aircraft Protocol and (y) those provisions of such Chapter II
that cannot be derogated from. In furtherance of the foregoing, the parties hereto agree
that the exercise of remedies hereunder and the other Operative Documents is subject to
other applicable law, including without limitation, the Uniform Commercial Code (as in
effect in the State of New York) and the Bankruptcy Code, and that nothing herein derogates
from the rights of Company or Loan Trustee under or pursuant to such other applicable law,
including without limitation, the Uniform Commercial Code (as in effect in the State of New
York) or the Bankruptcy Code.

     Upon every such taking of possession of Collateral under this Section 4.02, Loan Trustee may,
from time to time, at the expense of the Collateral, make all such expenditures for maintenance,
insurance, repairs, alterations, additions and improvements to and of the Collateral as it deems
necessary to cause the Collateral to be in such condition as required by the provisions of this
Indenture. In each such case, Loan Trustee may maintain, use, operate, store, insure, lease,
control, manage or dispose of the Collateral and may exercise all rights and powers of Company
relating to the Collateral as Loan Trustee reasonably deems best, including the right to enter into
any and all such agreements with respect to the maintenance, use, operation, storage, insurance,
leasing, control, management or disposition of the Collateral or any part thereof as Loan Trustee
may reasonably determine; and Loan Trustee shall be entitled to collect and receive

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

41

 

directly all
tolls, rents, revenues, issues, income, products and profits of the Collateral
and every part thereof without prejudice, however, to the rights of Loan Trustee under any
provision of this Indenture to collect and receive all cash held by, or required to be deposited
with Loan Trustee hereunder. Such tolls, rents, revenues, issues, income, products and profits
shall be applied to pay the expenses of the use, operation, storage, insurance, leasing, control,
management or disposition of the Collateral, and of all maintenance, repairs, replacements,
alterations, additions and improvements, and to make all payments that Loan Trustee is required or
elects to make, if any, for Taxes, insurance or other proper charges assessed against or otherwise
imposed upon the Collateral or any part thereof, and all other payments which Loan Trustee is
required or expressly authorized to make under any provision of this Indenture, as well as just and
reasonable compensation for the services of Loan Trustee, and shall otherwise be applied in
accordance with Article III. If an Event of Default has occurred and is continuing and the
Equipment Notes either have been accelerated pursuant to this Section 4.02 or have become due at
maturity and Loan Trustee is entitled to exercise rights hereunder, at the request of Loan Trustee,
Company shall promptly execute and deliver to Loan Trustee such instruments of title and other
documents as Loan Trustee reasonably deems necessary or advisable to enable Loan Trustee or an
agent or representative designated by Loan Trustee, at such time or times and place or places as
Loan Trustee specifies, to obtain possession of all or any part of the Collateral to which Loan
Trustee at the time is entitled hereunder. If Company for any reason fails to execute and deliver
such instruments and documents after such request by Loan Trustee, Loan Trustee may seek a judgment
conferring on Loan Trustee the right to immediate possession and requiring Company to execute and
deliver such instruments and documents to Loan Trustee, to the entry of which judgment Company
hereby specifically consents to the fullest extent it may lawfully do so. All actual and
reasonable expenses of obtaining such judgment or of pursuing, searching for and taking such
property shall, until paid, be secured by the Lien of this Indenture.

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

42

 

foreclosure of any Collateral. Company may also bid for and become the purchaser of any
Collateral offered for sale pursuant to this Section 4.02.

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

     (d) At any time after Loan Trustee has declared the unpaid principal amount of all Equipment
Notes then outstanding to be due and payable, or all Equipment Notes shall have become due and
payable as provided in the proviso to Section 4.02(a)(i), and, in either case, prior to the sale of
any part of the Collateral pursuant to this Article IV, a Majority in Interest of Noteholders, by
written notice to Company and Loan Trustee, may rescind and annul such declaration, whether made by
Loan Trustee on its own accord or as directed or deemed declaration, and its consequences if:
(i) there has been paid to or deposited with Loan Trustee an amount sufficient to pay all
overdue installments of principal amount of, and interest on, the Equipment Notes, and all other
amounts owing under the Operative Documents, that have become due otherwise than by such
declaration of acceleration and (ii) all other Events of Default, other than nonpayment of
principal amount or interest on the Equipment Notes that have become due solely because of such
acceleration, have been either cured or waived; provided that no such rescission or
annulment shall extend to or affect any subsequent default or Event of Default or impair any right
consequent thereon.

     (e) Notwithstanding anything contained herein, (i) so long as Pass Through Trustee
under any Pass Through Trust Agreement or Subordination Agent on its behalf is a Noteholder, Loan
Trustee will not be authorized or empowered to acquire title to any Collateral or take any action
with respect to any Collateral so acquired by it if such acquisition or action would cause any Pass
Through Trust to fail to qualify as a “grantor trust” for federal income tax purposes, and
(ii) Loan Trustee will not take any action that would violate Section 4.01(a)(ii) or
4.01(a)(iii) of the Intercreditor Agreement.

     Section 4.03 Remedies Cumulative. To the extent permitted under applicable law, each
and every right, power and remedy specifically given to Loan Trustee herein or otherwise in this
Indenture shall be cumulative and shall be in addition to every other right, power and remedy
specifically given herein or now or hereafter existing at law, in equity or by statute, and each
and every right, power and remedy whether specifically given herein or otherwise existing may be
exercised from time to time and as often and in such order as may be deemed expedient by Loan
Trustee, and the exercise or the beginning of the exercise of any power or remedy shall not be
construed to be a waiver of the right to exercise at the same time or thereafter any other right,
power or remedy. No delay or omission by Loan Trustee in the exercise of any right, remedy or
power or in the pursuance of any remedy shall, to the extent permitted by applicable law, impair
any such right, power or remedy or be construed to be a waiver of any default on the part of
Company or to be an acquiescence therein.

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

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

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

44

 

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

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

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

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

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

     Section 4.07 Appointment of a Receiver. To the extent permitted by applicable law, if
an Event of Default shall have occurred and be continuing, and the Equipment Notes either shall
have been accelerated pursuant to Section 4.02 or have become due at maturity, Loan Trustee shall,
as a matter of right, be entitled to the appointment of a receiver (who may be Loan Trustee or any
successor or nominee thereof) for all or any part of the Collateral, whether such receivership be
incidental to a proposed sale of the Collateral or the taking of possession thereof or otherwise,
and, to the extent permitted by applicable law, Company hereby consents to the appointment of such
a receiver and will not oppose any such appointment. Any receiver appointed for all or any part of
the Collateral shall be entitled to exercise all the rights and powers of Loan Trustee with respect
to the Collateral.

ARTICLE V

Duties of Loan Trustee

     Section 5.01 Notice of Event of Default. If Loan Trustee has knowledge of an Event of
Default or of a default arising from a failure by Company to pay when due any payment of principal
amount, interest on, or Make-Whole Amount, if any, due and payable under any Equipment Note, Loan
Trustee shall promptly give notice thereof to Company, each Liquidity Provider and each Noteholder.
Subject to the terms of Sections 4.02, 4.05, 5.02 and 5.03, Loan Trustee shall take such action,
or refrain from taking such action, with respect to such default or Event of Default (including
with respect to the exercise of any rights or remedies hereunder) as Loan Trustee is instructed in
writing by a Majority in Interest of Noteholders. Subject to the provisions of Section 5.03, if
Loan Trustee does not receive instructions as above provided within 20 Business Days after giving
notice of such default or Event of Default to Noteholders, Loan Trustee may, subject to
instructions thereafter received pursuant to the preceding provisions of this Section 5.01, take
such action, or refrain from taking such action with respect to such default or Event of Default as
it reasonably determines to be advisable in the best interests of Noteholders, but shall be under
no duty to take or refrain from taking any action. Loan Trustee shall use the same degree of care
and skill in connection therewith as a prudent person would use under the circumstances in the
conduct of his or her own affairs. Loan Trustee may not sell the Airframe or any Engine without
the consent of a Majority in Interest of Noteholders.

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

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

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

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

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

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

     Section 5.06 Investment of Amounts Held by Loan Trustee. Any monies (including for
the purpose of this Section 5.06 any amounts held by Loan Trustee pursuant to Section 3.02, 3.03 or
3.07 or pursuant to any provision of any other Operative
Document providing for amounts to be held by Loan Trustee which are not distributed pursuant
to the other provisions of Article III, or any cash received by Loan Trustee pursuant to Section
7.05(c) or 7.06(d) or otherwise, or Permitted Investments purchased by the use of such cash
pursuant to this Section 5.06 or any cash constituting the proceeds

of the maturity, sale or other disposition of any Permitted Investments) held by Loan Trustee
hereunder as part of the Collateral, until paid out by Loan Trustee as herein provided, (i)
subject to clause (ii) below and Section 3.07, may be carried by Loan Trustee on deposit with
itself or on deposit to its account with any bank, trust company or national banking association
incorporated or doing business under the laws of the United States or one of the states thereof
having combined capital and surplus and retained earnings of a least $100,000,000, and Loan Trustee
shall not have any liability for interest upon any such monies except as otherwise agreed in
writing with Company, or (ii) at any time and from time to time, so long as no Event of
Default shall have occurred and be continuing, at the request of Company, shall be invested and
reinvested in Permitted Investments as specified in such request (if such investments are
reasonably available for purchase) and sold, in any case at such prices, including accrued interest
or its equivalent, as are set forth in such request, and, as provided in Section 3.07, such
Permitted Investments shall be held by Loan Trustee in trust as part of the Collateral until so
sold; provided that Company shall upon demand pay to Loan Trustee the amount of any loss
realized upon maturity, sale or other disposition of any such Permitted Investment and, so long as
no Event of Default or Payment Default shall have occurred and be continuing, Company shall be
entitled to receive from Loan Trustee, and Loan Trustee shall promptly pay to Company, any profit,
income, interest, dividend or gain realized upon maturity, sale or other disposition of any
Permitted Investment. All Permitted Investments held by Loan Trustee pursuant to this Section 5.06
shall be held pursuant to Section 3.07. If an Event of Default or Payment Default shall have
occurred and be continuing, any net income, profit, interest, dividend or gain realized upon
maturity, sale or other disposition of any Permitted Investment shall be held as part of the
Collateral and shall be applied by Loan Trustee at the same time, on the same conditions and in the
same manner as the amounts in respect of which such income, profit, interest, dividend or gain was
realized are required to be distributed in accordance with the provisions hereof pursuant to which
such amounts were required to be held. Subject to Section 3.03, at such time as there shall not be
continuing any such Event of Default or Payment Default, such income, profit, interest, dividend or
gain shall be paid to Company. In addition, subject to Section 3.03, if any moneys or investments
are held by Loan Trustee solely because an Event of Default or Payment Default has occurred and is
continuing, at such time as there shall not be continuing any such Event of Default or Payment
Default, such moneys and investments shall be paid to Company. Loan Trustee shall not be
responsible for any losses on any investments or sales of Permitted Investments made pursuant to
the procedure specified in this Section 5.06 other than by reason of its willful misconduct or
negligence.

Loan Trustee

     Section 6.01 Acceptance of Trusts and Duties. U.S. Bank accepts the trusts and duties
hereby created and applicable to it and agrees to perform such duties, but only upon the terms of

     (v) install an Engine on an airframe owned by Company (or any Permitted Lessee) free
and clear of all Liens, except (A) Permitted Liens and Liens that apply only to the

this Section 7.02(a); and (B) either: (1) Company has obtained from
the lessor or secured party of such airframe a written agreement (which may be the lease,

satisfactory to Loan Trustee (an agreement from such lessor or secured party substantially
in the form of the penultimate paragraph of this Section 7.02(a) being deemed to be
satisfactory to Loan Trustee), whereby such lessor or secured party expressly agrees that
neither it nor its successors or assigns will acquire or claim any right, title or interest
in any Engine by reason of such Engine being installed on such airframe at any time while
such Engine is subject to the Lien of this Indenture, or (2) such lease,
conditional sale or other security agreement provides that such Engine shall not become
subject to the Lien of such lease, conditional sale or other security agreement at any time
while such Engine is subject to the Lien of this Indenture, notwithstanding its

that such installation shall be deemed an Event of Loss with respect to such Engine, and
Company shall comply with Section 7.05(b) in respect thereof, if such installation

intending hereby to waive any right or interest it may have to or in such Engine under

     (viii) lease any Engine or the Airframe and Engines to any United States air carrier
as to which there is in force a certificate issued pursuant to the Transportation Code (49

listed in Exhibit B hereto, (B) the manufacturer of the Airframe or any Engine
(either directly or through an affiliate) and (C) any foreign air carrier consented
to in writing by Loan Trustee with the consent of a Majority in Interest of Noteholders;
provided that (w) no Event of Default exists at the time such lease is
entered into, (x) in the case of a lease to any foreign air carrier (other than a

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

54

 

based at the time such lease is entered into and in the case of a lease to a foreign
air carrier principally based in Taiwan, the United States maintains diplomatic relations
with Taiwan at least as good as those on the Closing Date, (y) in the case of a
lease to any foreign air carrier, Company furnishes Loan Trustee with a certificate from a
Responsible Officer of Company certifying that there exist no possessory rights in favor of
such lessee under the laws of such lessee’s country which would, upon bankruptcy or
insolvency of or other default by Company, and assuming at such time such lessee is not
insolvent or bankrupt, prevent the taking of possession of any such Engine or the Airframe
and any such Engine by Loan Trustee in accordance with and when permitted by the terms of
Section 4.02 upon the exercise by Loan Trustee of its remedies under Section 4.02, and
(z) in the case of any lease to a foreign air carrier, such carrier is not then
subject to any bankruptcy, insolvency, liquidation, reorganization, dissolution or similar
proceeding and shall not have substantially all of its property in the possession of any
liquidator, trustee, receiver or similar person;

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

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

55

 

any Permitted Lessee) or by the lessor under such lease or subject to a security interest in
favor of the secured party under such conditional sale or other security agreement as the result of
such engine or engines being installed on the Airframe, or (B) any airframe owned by
Company (or any Permitted Lessee) or by the lessor under such lease or subject to a security
interest in favor of the secured party under such conditional sale or other security agreement as
the result of any Engine being installed on such airframe.

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

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

     (c) Maintenance. Company shall maintain, service, repair and overhaul the Aircraft
(or cause the same to be done) (i) so as to keep the Aircraft in good operating condition
and in such condition as may be necessary to enable the airworthiness certification of the Aircraft
to be maintained in good standing at all times (other than during temporary periods of storage,
during maintenance, testing or modification

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

56

 

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

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

     (e) Registration. Company shall cause the Aircraft to remain duly registered, under
the laws of the United States, in the name of Company except as otherwise required by the
Transportation Code; provided that Loan Trustee shall, at Company’s expense, execute and
deliver all such documents as Company may reasonably request for the purpose of continuing such
registration. Notwithstanding the preceding sentence, Company, at its own expense, may cause or
allow the Aircraft to be duly registered under the laws of any foreign jurisdiction in which a
Permitted Lessee could be principally based, in the name of Company or of any nominee of Company,
or, if required by applicable law, in the name of any other Person (and, following any such foreign
registration, may cause the Aircraft to be re-registered under the laws of the United States);
provided that in the case of jurisdictions other than those approved by Loan Trustee with
the consent of a Majority in Interest of Noteholders (i) if such jurisdiction is at the
time of registration listed on Exhibit B, Loan Trustee shall have received at the time of such
registration an opinion of counsel to Company to the effect that (A) this Indenture and
Loan Trustee’s right to repossession thereunder is valid and enforceable

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

57

 

under the laws of such country, (B) after giving effect to such change in
registration, the Lien of this Indenture shall continue as a valid Lien and shall be duly perfected
in the new jurisdiction of registration and that all filing, recording or other action necessary to
perfect and protect the Lien of this Indenture has been accomplished (or if such opinion cannot be
given at such time, (x) the opinion shall detail what filing, recording or other action is
necessary and (y) Loan Trustee shall have received a certificate from a Responsible Officer
of Company that all possible preparations to accomplish such filing, recording and other action
shall have been done, and such filing, recording and other action shall be accomplished and a
supplemental opinion to that effect shall be promptly delivered to Loan Trustee subsequent to the
effective date of such change in registration), (C) the obligations of Company under this
Indenture shall remain valid, binding and (subject to customary bankruptcy and equitable remedies
exceptions and to other exceptions customary in foreign opinions generally) enforceable under the
laws of such jurisdiction (or the laws of the jurisdiction to which the laws of such jurisdiction
would refer as the applicable governing law), (D) all approvals or consents of any
government in such jurisdiction having jurisdiction required for such change in registration shall
have been duly obtained and shall be in full force and effect and (E) (unless Company shall
have agreed to provide insurance covering the risk of requisition of use or title of the Aircraft
by the government of such jurisdiction so long as the Aircraft is registered under the laws of such
jurisdiction) the laws of such jurisdiction require fair compensation by the government of such
jurisdiction payable in currency freely convertible into Dollars for the loss of use or title of
the Aircraft in the event of requisition by such government of such use or title, and (ii)
if such jurisdiction is at the time of registration not listed on Exhibit B, Loan Trustee shall
have received (in addition to the opinions set forth in clause (i) above) at the time of such
registration an opinion of counsel to Company to the effect that (A) the terms of this
Indenture are legal, valid, binding and enforceable in such jurisdiction (subject to exceptions
customary in such jurisdiction; provided that, subject to exceptions relating to
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of
creditors generally and exceptions relating to general principles of equity, such counsel shall
opine that any applicable laws limiting the remedies provided in Section 4.02 do not in the opinion
of such counsel make the remedies provided in Section 4.02 inadequate for the practical realization
of the rights and benefits provided thereby), (B) it is not necessary for Loan Trustee to
register or qualify to do business in such jurisdiction and (C) there is no tort liability
of the lender of an aircraft not in possession thereof under the laws of such jurisdiction other
than tort liability that might have been imposed on such lender under the laws of the United States
or any state thereof (it being understood that such opinion shall be waived if insurance reasonably
satisfactory to Loan Trustee is provided, at Company’s expense, to cover such risk). Loan Trustee
will cooperate with Company in effecting such foreign registration. Notwithstanding the foregoing,
prior to any such change in the country of registry of the Aircraft, the following conditions shall
be met (or waived as provided in Section 6.01(b) of the Participation Agreement):

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

58

 

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

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

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

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

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

     (a) Inspection. At all reasonable times, but upon at least 15 Business Days’ prior
written notice to Company, Loan Trustee or its authorized representatives may, subject to the other
conditions of this Section 7.03(a), inspect the Aircraft and may inspect the books and records of
Company relating to the maintenance of the Aircraft required to be maintained by the FAA or the
government of another jurisdiction in which the Aircraft is then registered; provided that
(i) Loan Trustee or its representatives, as the case may be, shall be fully insured at no
cost to Company or any Permitted Lessee in a manner satisfactory to Company with respect to any
risks incurred in connection with any such inspection or shall provide to Company a written release
satisfactory to Company and any Permitted Lessee with respect to such risks, (ii) any such

hours and subject to the safety, security and workplace rules applicable at the location where such
inspection is conducted and any applicable governmental rules or regulations, (iii) any
such inspection of the Aircraft shall be a visual, walk-around inspection of the interior and
exterior of the Aircraft and shall not include opening any panels, bays or the like without
Company’s express consent, which consent Company may in its sole discretion withhold, and
(iv) no exercise of such inspection right shall interfere with the use, operation or
maintenance of the Aircraft by, or the business of, Company or any Permitted Lessee and Company and
any Permitted Lessee shall not be required to undertake or incur any additional liabilities in
connection therewith. All information obtained in connection with any such inspection of the
Aircraft and of such books and records shall be Confidential Information and shall be treated by
Loan Trustee and its representatives in accordance with the provisions of Section 10.16. Any
inspection pursuant to this Section 7.03(a) shall be at the sole risk (including, without
limitation, any risk of personal injury or death) and expense of Loan Trustee (or its
representatives) making such inspection. Except during the continuance of an Event of Default, all
inspections by Loan Trustee and its representatives provided for under this Section 7.03(a) shall
be limited to one inspection of any kind contemplated by this Section 7.03(a) during any
consecutive twelve month period.

     (b) Financial Information. So long as any of the Secured Obligations remain unpaid,
Company agrees to furnish to Loan Trustee: (i) within 60 days after the end of each of the
first three quarterly periods in each fiscal year of Company, either (x) a consolidated

and clause (ii) above if Loan Trustee so requests.

     Section 7.04 Replacement and Pooling of Parts; Alterations, Modifications and Additions;
Substitution of Engines.

     (a) Replacement of Parts. Company shall promptly replace or cause to be replaced all
Parts incorporated or installed in or attached to the Airframe or any Engine and that become worn
out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or rendered permanently
unfit for use for any reason, except as otherwise provided in Section 7.04(c) or if the Airframe or
an Engine to which a Part relates has suffered an Event of Loss. In addition, Company (or any
Permitted Lessee) may remove in the ordinary course of maintenance, service, repair, overhaul or
testing, any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged
beyond repair or rendered permanently unfit for use; provided that Company (or any
Permitted Lessee), except as otherwise provided in Section 7.04(c), will replace such Parts as
promptly as practicable. All replacement Parts shall be free and clear of all Liens (except for
Permitted Liens and except in the case of replacement property temporarily installed on an
emergency basis) and shall be in the condition and repair required to be maintained by the terms
hereof. Except as otherwise provided in Section 7.04(c), any Part removed from the Airframe or any
Engine shall remain subject to the Lien of this Indenture no matter where located until it is
replaced by a part incorporated or installed in or attached to the Airframe or such Engine that
meets the requirements for replacement Parts specified above. Immediately upon any replacement
Part becoming incorporated or installed in or attached to the Airframe or any Engine as above
provided (except in the case of replacement property temporarily installed on an emergency basis),
without further act, (i) the replaced Part shall thereupon be free and clear of all rights
of Loan Trustee and of the Lien of this Indenture and shall no longer be deemed a Part hereunder,
and (ii) such replacement Part shall become subject to the Lien of this Indenture and be
deemed a Part of the Airframe or such Engine for all purposes to the same extent as the Parts
originally incorporated or installed in or attached to the Airframe or such Engine. Upon request
of Company from time to time, Loan Trustee shall execute and deliver to Company an appropriate
instrument confirming the release of any such replaced Part from the Lien of this Indenture.

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

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

62

 

Engine pursuant to the first sentence of this Section 7.04(c) and (iii) can be removed
from the Airframe or such Engine without materially diminishing the value or utility required to be
maintained by the terms of this Indenture that the Airframe or such Engine would have had had such
Part never been installed on the Airframe or such Engine. Upon the removal by Company (or any
Permitted Lessee) of any Part as permitted by this Section 7.04(c), such removed Part shall,
without further act, be free and clear of all rights and interests of Loan Trustee and the Lien of
this Indenture and shall no longer be deemed a Part hereunder. Upon request of Company from time
to time, Loan Trustee shall execute and deliver to Company an appropriate instrument confirming the
release of any such removed Part from the Lien of this Indenture. Loan Trustee acknowledges that
it has no interest in the Excluded Equipment. Notwithstanding the provisions of this Section
7.04(c) or any other term or condition of this Indenture, Company (or any Permitted Lessee) may
from time to time install on, and remove from, the Aircraft equipment that is owned by, leased to
or conditionally sold to Company (or any Permitted Lessee) (and title to such equipment shall
remain vested in Company, such Permitted Lessee, or the lessor or the conditional vendor thereof)
if (1) such equipment is Excluded Equipment and (2) the location affected by any
such removal, if damaged, is repaired prior to return, in a workmanlike manner, to a condition
suitable for commercial passenger service; provided that all costs of installation, removal
and replacement shall be the responsibility of Company.

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

     Section 7.05 Loss, Destruction or Requisition.

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

63

 

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

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

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

     If Company elects to substitute a Replacement Airframe (or a Replacement Airframe and one or
more Replacement Engines, as the case may be) Company shall, at its sole expense, not later than
the Loss Payment Date, (A) cause an Indenture Supplement for such Replacement Airframe and
Replacement Engines, if any, to be delivered to Loan Trustee for execution and, upon such
execution, to be filed for recordation pursuant to the Transportation Code or the applicable laws
of such other jurisdiction in which the Aircraft is then registered, (B) cause the sale of
such Replacement Airframe and Replacement Engines, if any, to Company (if occurring after February
28, 2006 and if the seller of such Replacement Airframe and Replacement Engines, if any, is
“situated in” a country that has ratified the Cape Town Convention) and the International Interest
created pursuant to the Indenture Supplement in favor of Loan Trustee with respect to such
Replacement Airframe and Replacement Engines, if any, each to be registered on the International
Registry as a sale or an International Interest, respectively; provided that if the seller
of such Replacement Airframe and Replacement Engines, if any, is not situated in a country that has
ratified the Cape Town Convention, Company will use its best efforts to cause the seller to
register the contract of sale on the International Registry, (C) cause a financing
statement or statements with respect to the Replacement Airframe and Replacement Engines, if any,
or other requisite documents or instruments to be filed in such place or places as necessary in
order to perfect Loan Trustee’s interest therein in the United States, or in any other jurisdiction
in which the Aircraft is then registered, (D) furnish Loan Trustee with an opinion of
Company’s counsel (which may be internal counsel of Company) addressed to Loan

Trustee to the effect that upon such replacement, such Replacement Airframe and Replacement
Engines, if any, will be subject to the Lien of this Indenture and addressing the matters set forth
in clauses (A), (B) and (C), (E) furnish Loan Trustee with a certificate of an independent
aircraft engineer or appraiser, certifying that the Replacement Airframe and Replacement Engines,
if any, have a value and utility (without regard to hours or cycles) at least equal to the Airframe
and Engines, if any, so replaced, assuming the Airframe and such Engines were in the condition and
repair required by the terms hereof immediately prior to the occurrence of such Event of Loss,
(F) furnish Loan Trustee with evidence of compliance with the insurance provisions of
Section 7.06 with respect to such Replacement Airframe and Replacement Engines, if any, (G)
furnish Loan Trustee with a copy of the original bill of sale respecting such Replacement Airframe
and a copy of the original bill of sale or, if the bill of sale is unavailable, other evidence of
ownership reasonably satisfactory to Loan Trustee (which may be a copy of an invoice or purchase
order) respecting such Replacement Engines, if any, and (H) furnish Loan Trustee with an
opinion of Company’s counsel (which may be internal counsel of Company) reasonably satisfactory to
Loan Trustee to the effect that Loan Trustee will be entitled to the benefits of Section 1110 with
respect to the Replacement Airframe; provided that (i) such opinion need not be
delivered to the extent that the benefits of Section 1110 were not, by reason of a change in law or
governmental or judicial interpretation thereof, available to Loan Trustee with respect to the
Aircraft immediately prior to such substitution and (ii) such opinion may contain
qualifications and assumptions of the tenor contained in the Section 1110 opinion of Company’s
counsel delivered pursuant to Section 3.01 of the Participation Agreement on the Closing Date and
such other qualifications and assumptions as are at the time customary in opinions rendered in
comparable circumstances.

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

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

     If, after an Event of Loss, Company performs the option set forth in clause (ii) of the first
paragraph of this Section 7.05(a), Loan Trustee shall execute and deliver to Company an appropriate
instrument releasing the Aircraft, all proceeds (including, without limitation, insurance
proceeds), the Warranty Rights in respect of the Aircraft and all rights relating to the foregoing
from the Lien of this Indenture and assigning to Company all claims against third Persons for
damage to or loss of the Aircraft arising from the Event of Loss, and will take such actions as may
be required to be taken by Loan Trustee to cancel or release any International Interest of Loan
Trustee registered with the International Registry in relation to the Airframe and Engines, if any,
with respect to which such Event of Loss occurred.

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

     Prior to or at the time of any replacement under this Section 7.05(b), Company will
(i) cause an Indenture Supplement covering such Replacement Engine to be delivered to Loan
Trustee for execution and, upon such execution, to be filed for recordation pursuant to the
Transportation Code or the applicable laws of any other jurisdiction in which the Aircraft is then
registered, (ii) furnish Loan Trustee with a copy

[Reg. No.]

66

 

of the original bill of sale or, if the bill of sale is unavailable, other evidence of
ownership reasonably satisfactory to Loan Trustee (which may be a copy of an invoice or purchase
order) respecting such Replacement Engine, which in the case of any such conveyance to which the
Cape Town Convention is applicable shall be in such form as will qualify as “contract of sale”
pursuant to Article V of the Aircraft Protocol, and all documents required under the Operative
Documents to establish, continue, confirm, register and/or perfect the interests of Loan Trustee in
such Replacement Engine, (iii) cause the sale of such Replacement Engine to Company (if
occurring after February 28, 2006 and if the seller of such Replacement Engine is “situated in” a
country that has ratified the Cape Town Convention) and the International Interest created pursuant
to the Indenture Supplement in favor of Loan Trustee with respect to such Replacement Engine, each
to be registered on the International Registry as a sale or an International Interest,
respectively; provided that if the seller of such Replacement Engine is not situated in a
country that has ratified the Cape Town Convention, Company will use its best efforts to cause the
seller to register the contract of sale on the International Registry, (iv) cause a
financing statement or statements with respect to such Replacement Engine or other requisite
documents or instruments to be filed in such place or places as necessary in order to perfect Loan
Trustee’s interest therein in the United States, or in such other jurisdiction in which the Engine
is then registered, (v) furnish Loan Trustee with an opinion of Company’s counsel (which
may be internal counsel to Company) addressed to Loan Trustee to the effect that, upon such
replacement, the Replacement Engine will be subject to the Lien of this Indenture, (vi)
furnish Loan Trustee with a certificate of an aircraft engineer or appraiser (who may be an
employee of Company) certifying that such Replacement Engine has a value and utility (without
regard to hours or cycles) at least equal to the Engine so replaced assuming such Engine was in the
condition and repair required by the terms hereof immediately prior to the occurrence of such Event
of Loss and (vii) furnish Loan Trustee with evidence of compliance with the insurance
provisions of Section 7.06 with respect to such Replacement Engine. In the case of each
Replacement Engine subjected to the Lien of this Indenture under this Section 7.05(b), promptly
upon the recordation of the Indenture Supplement covering such Replacement Engine pursuant to the
Transportation Code (or pursuant to the applicable law of such other jurisdiction in which the
Aircraft is registered), Company will cause to be delivered to Loan Trustee an opinion of FAA
counsel selected by Company if at the time of the Event of Loss the Aircraft was registered under
the laws of the United States (or, if at the time of the Event of Loss the Aircraft was registered
under the laws of another jurisdiction, counsel qualified to opine on matters of registration in
such jurisdiction selected by Company, which counsel shall be reasonably satisfactory to Loan
Trustee) addressed to Loan Trustee as to the due recordation of such Indenture Supplement or such
other requisite documents or instruments, the registration with the International Registry of the
sale of such Replacement Engine to Company (if occurring after February 28, 2006) and of the
International Interest created pursuant to the Indenture Supplement with respect to such
Replacement Engine and the validity and perfection of the security interest in the Replacement
Engine granted to Loan Trustee under this

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

67

 

Indenture. For all
purposes hereof, upon the attachment of the Lien of this Indenture thereto, the Replacement
Engine shall become part of the Collateral and shall be deemed an “Engine” as defined
herein. Upon compliance with clauses (i) through (vii) of the first sentence of this paragraph,
Loan Trustee shall execute and deliver to Company an appropriate instrument releasing such replaced
Engine, any proceeds (including, without limitation, insurance proceeds), the Warranty Rights in
respect of such replaced Engine and all rights relating to any of the foregoing from the Lien of
this Indenture and assigning to Company all claims against third Persons for damage to or loss of
such Engine arising from the Event of Loss, and will take such actions as may be required to be
taken by Loan Trustee to cancel or release any International Interest of Loan Trustee registered
with the International Registry in relation to the Engines with respect to which such Event of Loss
occurred.

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

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

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

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

68

 

performed its obligations under Section 7.05(b) with respect to the Event of Loss for
which such payments are made.

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

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

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

     Section 7.06 Insurance.

     (a) Aircraft Liability Insurance.

	           (i)	 	Except as provided in clause (ii) of this Section 7.06(a), and subject to the
rights of Company to establish and maintain self-insurance in the

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

69

 

manner and to the extent specified in Section 7.06(d), Company will carry, or cause to
be carried, at no expense to Loan Trustee, aircraft liability insurance (including, but not
limited to, passenger, contractual, bodily injury, personal injury and property damage
liability (exclusive of manufacturer’s product liability insurance and war risk, hijacking
and related perils insurance)) with respect to the Aircraft that is of the type as from
time to time applicable to aircraft operated by Company (or, if a Lease in respect of the
Aircraft is then in effect, by Permitted Lessee) of the same type as the Aircraft
(A) in amounts that are not less than the aircraft liability insurance applicable
to similar aircraft and engines in Company’s fleet on which Company carries insurance and
operated by Company on the same or similar routes as operated by the Aircraft;
provided that such liability insurance shall not be less than the amount (the
“Minimum Insurance Amount”) certified in the insurance report delivered to Loan
Trustee and each Liquidity Provider on the Closing Date, and (B) that is
maintained in effect with insurers of recognized responsibility. Any policies of insurance
carried in accordance with this Section 7.06(a) and any policies taken out in substitution
or replacement for any of such policies shall: (1) name Loan Trustee,
Subordination Agent, each Pass Through Trustee and each Liquidity Provider as their
Interests (defined below in this Section 7.06) may appear, as additional insureds (the
“Additional Insureds”), (2) subject to the conditions of clause (3) below,
provide that, in respect of the interest of each Additional Insured in such policies, the
insurance shall not be invalidated by any action or inaction of Company, any Permitted
Lessee, or any other insured (other than such Additional Insured) and shall insure each
Additional Insured’s Interests as they appear, regardless of any breach or violation of any
warranty, declaration or condition contained in such policies by Company, any Permitted
Lessee or any other insured (other than such Additional Insured), (3) provide that,
if such insurance is canceled for any reason, or if any change is made in the insurance
that materially reduces the amount of insurance or the coverage certified in the insurance
report delivered on the Closing Date to Loan Trustee and each Liquidity Provider, or if
such insurance is canceled for nonpayment of premium, such cancellation or change shall not
be effective as to any Additional Insured for 30 days after receipt by such Additional
Insured of written notice from such insurers of such cancellation or change, (4)
provide that the Additional Insureds shall have no obligation or liability for premiums,
commissions, assessments or calls in connection with such insurance, (5) provide
that the insurers shall waive any rights of (x) set-off, counterclaim or any other
deduction, whether by attachment or otherwise, in respect of any liability of the
Additional Insureds to the extent of any moneys due to the Additional Insureds and
(y) subrogation against the Additional Insureds to the extent that Company has
waived its rights by its agreements to indemnify the Additional Insureds pursuant to the
Operative Documents, (6) be primary without right of contribution from any other
insurance carried by any Additional Insured with respect to its Interests as such in the
Aircraft and (7) expressly provide that all of the provisions

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

70

 

thereof, except the limits of liability, shall operate in the same manner as if there
were a separate policy covering each insured. “Interests” as used in this Section
7.06(a) and in Sections 7.06(b) and 7.06(c) with respect to any Person means the interests
of such Person in the transactions contemplated by the Operative Documents.

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

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

71

 

operated by the Aircraft, the Airframe or such Engine, then Company shall maintain or cause to
be maintained with respect to the Aircraft war risk, hijacking and related perils liability
insurance in scope and coverage no less comprehensive, in an amount not less than the insurance
maintained by Company (or such Permitted Lessee, as the case may be) with respect to such other
aircraft, and with insurers of recognized responsibility. Any policies of insurance carried in
accordance with this Section 7.06(b) and any policies taken out in substitution or replacement for
any of such policies shall: (1) name Loan Trustee, Subordination Agent, each Pass Through
Trustee and each Liquidity Provider as their Interests may appear, as Additional Insureds,
(2) subject to the conditions of clause (3) below (other than the exception set forth
therein), provide that, in respect of the interest of each Additional Insured in such policies, the
insurance shall not be invalidated by any action or inaction of Company, any Permitted Lessee, or
any other insured (other than such Additional Insured) and shall insure each Additional Insured’s
Interests as they appear, regardless of any breach or violation of any warranty, declaration or
condition contained in such policies by Company, any Permitted Lessee, or any other insured (other
than such Additional Insured), (3) provide that, except to the extent not provided for by
Company’s war risk and allied perils insurance provider, if such insurance is canceled for any
reason, or if any change is made in the insurance that materially reduces the amount of insurance
or the coverage certified in the insurance report delivered on or prior to the Closing Date to Loan
Trustee and each Liquidity Provider or, if such insurance is canceled for nonpayment of premium,
such cancellation or change shall not be effective as to any Additional Insured for seven days (or
such other period as is then generally available in the industry) after receipt by such Additional
Insured of written notice from such insurers of such cancellation or change, (4) provide
that the Additional Insureds shall have no obligation or liability for premiums, commissions,
assessments or calls in connection with such insurance, (5) provide that the insurers shall
waive any rights of (x) set-off, counterclaim or any other deduction, whether by attachment
or otherwise, in respect of any liability of the Additional Insureds to the extent of any moneys
due to the Additional Insureds and (y) subrogation against the Additional Insureds to the
extent that Company has waived its rights by its agreements to indemnify the Additional Insureds
pursuant to the Operative Documents, (6) be primary without right of contribution from any
other insurance carried by any Additional Insured with respect to its Interests as such in the
Aircraft and (7) expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy covering each
insured. To the extent that Company’s war risk and allied perils insurance provider does not
provide for provision of direct notice to Additional Insureds of cancellation or change in the
insurance required hereunder, Company hereby agrees that upon receipt of notice of any thereof from
such insurance provider it shall give the Additional Insureds immediate notice of each cancellation
or change to such insurance.

     (c) Insurance Against Loss or Damage to Aircraft.

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

72

 

     (i) Except as provided in clause (ii) of this Section 7.06(c), and subject to the
rights of Company to establish and maintain self-insurance in the manner and to the extent
specified in Section 7.06(d) below, Company shall maintain, or cause to be maintained, in
effect with insurers of recognized responsibility, at no expense to Loan Trustee, all-risk
aircraft hull insurance covering the Aircraft and all-risk coverage with respect to any
Engines or Parts while removed from the Aircraft (including, but not limited to, war risk
insurance, if and to the extent the same is maintained by Company (or, if a Lease is then
in effect, by the Permitted Lessee) with respect to other similar aircraft operated by
Company or such Permitted Lessee, as the case may be, on the same routes) that is of the
type as from time to time applicable to aircraft operated by Company (or, if a Lease is
then in effect, by the Permitted Lessee) of the same type as the Aircraft; provided
that (A) such insurance (including the permitted self-insurance) shall at all times
while the Aircraft is subject to this Indenture be for an amount not less than 110% of the
aggregate principal amount of the Equipment Notes outstanding from time to time,
(B) such insurance need not cover an Engine while attached to an airframe not
owned, leased or operated by Company, and (C) such insurance covering Engines and
Parts removed from an Airframe or an airframe or (in the case of Parts) an Engine need be
obtained only to the extent available at reasonable cost (as reasonably determined by
Company). Any policies carried in accordance with this Section 7.06(c) and any policies
taken out in substitution or replacement for any such policies shall: (1) provide
that any insurance proceeds up to an amount equal to the outstanding principal amount of
the Equipment Notes, together with accrued but unpaid interest thereon, plus an amount
equal to the interest that would accrue on the outstanding principal amount of the
Equipment Notes at the Debt Rate in effect on the date of payment of such insurance
proceeds to Loan Trustee (as provided for in this sentence) during the period commencing on
the day following the date of such payment to Loan Trustee and ending on the Loss Payment
Date (the sum of such three amounts being the “Loan Amount”), payable for any loss
or damage constituting an Event of Loss with respect to the Aircraft and any insurance
proceeds in excess of the Insurance Threshold up to an amount equal to the Loan Amount for
any loss or damage to the Aircraft (or Engines) not constituting an Event of Loss with
respect to the Aircraft (or Engines), shall be paid to Loan Trustee as long as the
Indenture has not been discharged, and that all other amounts shall be paid to Company,
unless the insurer has received notice that an Event of Default exists, in which case all
insurance proceeds for any loss or damage to the Aircraft (or Engines) up to an amount
equal to the Loan Amount shall be payable to Loan Trustee, (2) subject to the
conditions of clause (C) below (other than the exception set forth therein), provide that,
in respect of the interest of each Additional Insured in such policies, the insurance shall
not be invalidated by any action or inaction of Company, any Permitted Lessee, or any other
insured (other than such Additional Insured) and shall insure each Additional Insured’s
Interests as they appear,

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

73

 

regardless of any breach or violation of any warranty, declaration or condition
contained in such policies by Company, any Permitted Lessee or any other insured (other
than such Additional Insured), (3) provide that, except to the extent not provided
for by Company’s hull war risk and allied perils insurance provider, if such insurance is
canceled for any reason, or if any change is made in the insurance that materially reduces
the coverage (not including the amount) certified in the insurance report delivered on the
Closing Date to Loan Trustee, and each Liquidity Provider or, if such insurance is canceled
for nonpayment of premium, such cancellation or change shall not be effective as to the
Additional Insureds for 30 days (seven days, or such other period as is then customary in
the industry, in the case of war risk or allied perils coverage) after receipt by the
Additional Insureds of written notice from such insurers of such cancellation or change,
(4) provide that the Additional Insureds shall have no obligation or liability for
premiums, commissions, assessments or calls in connection with such insurance, (5)
provide that the insurers shall waive rights of (x) setoff, counterclaim or any
other deduction, whether by attachment or otherwise, in respect of any liability of the
Additional Insureds to the extent of any moneys due to the Additional Insureds and
(y) subrogation against the Additional Insureds to the extent Company has waived
its rights by its agreement to indemnify the Additional Insureds pursuant to the Operative
Documents, and (6) be primary without right of contribution from any other
insurance carried by any Additional Insured with respect to its Interests as such in the
Aircraft. To the extent that Company’s war risk and allied perils insurance provider does
not provide for provision of direct notice to Additional Insureds of cancellation or change
in the insurance required hereunder, Company hereby agrees that upon receipt of notice of
any thereof from such insurance provider it shall give the Additional Insureds immediate
notice of each cancellation or change to such insurance.

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

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

74

 

principal amount of the Equipment Notes during such period that such Airframe or
Engine is on the ground and not being flown.

     (d) Self-Insurance. Company may from time to time self-insure, by way of deductible,
self-insured retention, premium adjustment or franchise or otherwise (including, with respect to
insurance maintained pursuant to Sections 7.06(a), 7.06(b) or 7.06(c), insuring for a maximum
amount that is less than the amounts set forth in Sections 7.06(a), 7.06(b) and 7.06(c) above), the
risks required to be insured against pursuant to Sections 7.06(a), 7.06(b) and 7.06(c) above, but
in no case shall the self-insurance with respect to all of the aircraft and engines in the combined
fleet of Company and its Affiliates (including, without limitation, the Aircraft) exceed for any
12-month policy year 1.0% of the average aggregate insurable value (during the preceding policy
year) of all aircraft (including, without limitation, the Aircraft) on which Company and its
Affiliates carry insurance, unless an insurance broker of national standing certifies that the
standard among other major United States airlines is a higher level of self-insurance, in which
case Company may self-insure the Aircraft to such higher level; provided that (1)
any deductible per occurrence that, in the case of the Aircraft, is not in excess of the amount
customarily allowed as a deductible in the industry or is required to facilitate claims handling or
(2) any applicable mandatory minimum per aircraft (or if applicable per annum or other
period) hull or liability insurance deductibles imposed by the aircraft hull or liability insurers
shall be permitted in addition to the above-mentioned self-insurance.

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

     (f) Application of Insurance Payments. All losses will be adjusted by Company with
the insurers. As between Loan Trustee and Company it is agreed that all insurance payments
received under policies required to be maintained by Company hereunder, exclusive of any payments
received in excess of the Loan Amount for the Aircraft from such policies, as the result of the
occurrence of an Event of Loss with respect to the Airframe or an Engine will be applied as
follows:

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

75

 

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

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

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

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

     The insurance payments for any loss or damage to the Airframe or an Engine not constituting an
Event of Loss with respect to the Airframe or such Engine will be applied in payment (or to
reimburse Company) for repairs or for replacement property in accordance with the terms of Sections
7.02 and 7.04, and any balance remaining after compliance with such Sections with respect to such
loss or damage shall be paid to Company. Any amount referred to in the preceding sentence or in
clause (i) or (ii) of the first paragraph of this Section 7.06(f) that is payable to Company shall
not be paid to Company (or, if it has been previously paid directly to Company, shall not be
retained by Company) if at the time of such payment an Event of Default or Payment Default has
occurred and is continuing, but shall be paid to and held by Loan Trustee as security for the
obligations of Company under this Indenture and the other Operative Documents and shall be invested
pursuant to Section 5.06 unless and until such amount is applied, at the option of Loan Trustee, to
Company’s obligations under this Indenture and the other

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

76

 

Operative Documents as and when due, it being understood that any such application shall be
made to such obligations of Company as Loan Trustee may determine in its sole discretion. At such
time as there shall be continuing no Event of Default or Payment Default, such amount shall be paid
to Company to the extent not previously applied in accordance with this Section 7.06(f).

     (g) Reports, Etc. On or before the Closing Date and annually following renewal of
Company’s insurance coverage, Company will furnish to Loan Trustee and each Liquidity Provider
current certificates of insurance and a report signed by a firm of independent aircraft insurance
brokers appointed by Company (which brokers may be in the regular employ of Company), stating the
opinion of such firm that the insurance then carried and maintained on the Aircraft complies with
the terms hereof. All information contained in such report shall be Confidential Information and
shall be treated by Loan Trustee and each Liquidity Provider and each of their Affiliates and their
respective officers, directors, agents and employees in accordance with the provisions of Section
10.16. Company will cause such firm to notify Loan Trustee and each Liquidity Provider of any act
or omission on the part of Company of which such firm has knowledge that might invalidate or render
unenforceable, in whole or in part, any insurance on the Aircraft. Company will also cause such
firm to notify Loan Trustee and each Liquidity Provider as promptly as practicable after such firm
acquires knowledge that a cancellation of any insurance carried and maintained on the Aircraft
pursuant to this Section 7.06 will occur. Such information may only be provided to other Persons
in accordance with Section 10.16.

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

     (e) Salvage Rights; Other. All salvage rights to the Airframe and each Engine shall
remain with Company’s insurers at all times, and any insurance policies of Loan Trustee insuring
the Airframe or any Engine shall provide for a release to Company of any and all salvage rights in
and to the Airframe or any Engine. Neither Loan Trustee nor any Noteholder may, directly or
indirectly, obtain insurance for its own account with respect to the Airframe or any Engine if such
insurance would limit or otherwise

Indenture and Security Agreement (2010-2 EETC)

[Reg. No.]

77

 

adversely affect the coverage or amounts payable under, or increase the premiums for, any
insurance required to be maintained pursuant to this Section 7.06 or any other insurance maintained
with respect to the Aircraft or any other aircraft in Company’s fleet.

ARTICLE VIII

Successor and Additional Trustees

     Section 8.01 Resignation or Removal; Appointment of Successor.

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

     (b) Any successor Loan Trustee, however appointed, shall execute and deliver to the
predecessor Loan Trustee and Company an instrument accepting such appointment and assuming the
obligations of Loan Trustee arising from and after the time of such appointment, and thereupon such
successor Loan Trustee, without further act, shall become vested with all the estates, properties,
rights, powers and duties of the predecessor Loan Trustee in the trust hereunder applicable to it
with like effect as if originally named Loan Trustee herein; but nevertheless upon the written
request of such successor Loan Trustee, such predecessor Loan Trustee shall execute and deliver an
instrument transferring to such successor Loan Trustee all the estates, properties, rights

Indenture and Security Agreement (2010-2 EETC)
[Reg. No.]

78

 

and powers of such predecessor Loan Trustee, and such predecessor Loan Trustee shall duly assign,
transfer, deliver and pay over to such successor Loan Trustee all monies or other property and all
other books and records, or true, correct and complete copies thereof, then held by such
predecessor Loan Trustee.

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

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

     Section 8.02 Appointment of Additional and Separate Trustees.

     (a) Whenever (i) Loan Trustee deems it necessary or desirable in order to conform to
any law of any jurisdiction in which all or any part of the Collateral is situated or to make any
claim or bring any suit with respect to or in connection with the Collateral, any Operative
Document or any of the transactions contemplated by the Operative Documents, (ii) Loan
Trustee shall be advised by counsel satisfactory to it that it is necessary or prudent in the
interests of Noteholders (and Loan Trustee shall so advise
Company) or (iii) Loan Trustee has been requested to do so by
a Majority in Interest of

Indenture and Security Agreement (2010-2 EETC)
[Reg. No.]

79

 

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

     (b) No additional or separate trustee shall be entitled to exercise any of the rights, powers,
duties and obligations conferred upon Loan Trustee in respect of the custody, investment and
payment of monies and all monies received by any such additional or separate trustee from or
constituting part of the Collateral or otherwise payable under any Operative Documents to Loan
Trustee shall be promptly paid over by it to Loan Trustee. All other rights, powers, duties and
obligations conferred or imposed upon any additional or separate trustee shall be exercised or
performed by Loan Trustee and such additional or separate trustee jointly except to the extent that
applicable law of any jurisdiction in which any particular act is to be performed renders Loan
Trustee incompetent or unqualified to perform such act, in which event such rights, powers, duties
and obligations (including the holding of title to all or part of the Collateral in any such
jurisdiction) shall be exercised and performed by such additional or separate trustee.
No additional or separate trustee shall take any discretionary action except on the

Indenture and Security Agreement (2010-2 EETC)
[Reg. No.]

80

 

instructions of Loan Trustee or a Majority in Interest of Noteholders. No trustee hereunder shall
be personally liable by reason of any act or omission of any other trustee hereunder, except that
Loan Trustee shall be liable for the consequences of its lack of reasonable care in selecting, and
Loan Trustee’s own actions in acting with, any additional or separate trustee. Each additional or
separate trustee appointed pursuant to this Section 8.02 shall be subject to, and shall have the
benefit of Articles IV, V, VI, VIII, IX and X insofar as they apply to Loan Trustee. The powers of
any additional or separate trustee appointed pursuant to this Section 8.02 shall not in any case
exceed those of Loan Trustee.

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