 It is expressly agreed that notwithstanding anything herein to the contrary, Company shall
remain liable under the Purchase Agreement to perform all of its obligations thereunder, and, except to the extent expressly provided in any Operative Document, none of Loan Trustee, any Noteholder, any other Indenture Indemnitee, any Related

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

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.

hereby assigned, to any Person other than Loan Trustee, except as otherwise provided in or permitted by any Operative Document.

 For purposes hereof, the term “Indenture” means the Indenture and Security
Agreement (N626QX), dated as of July 2, 2020, between Company and U.S. Bank Trust National Association, as Loan Trustee (“Loan Trustee”), as the same may be amended, supplemented or otherwise modified from time to time in
accordance with its terms. All capitalized terms used in this Equipment Note and not defined herein, unless the context otherwise requires, shall have the respective meanings set forth or incorporated by reference, and shall be construed and
interpreted in the manner described, in the Indenture. 
 This Equipment Note shall bear interest, payable on demand, at the Past Due Rate
(and not the Debt Rate) (calculated on the basis of a year of 360 days 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

 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, this 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

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, Series B Equipment Notes (if issued) and one or more Additional Series Equipment Notes (if issued) and (b) the maturities and principal amounts and shall
bear interest at the applicable Debt Rates specified in Schedule I hereto (as, in the case of any Series B Equipment Notes or any Additional Series Equipment Notes issued after the Closing Date, 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 (if issued) shall be issued to Subordination Agent on behalf of Pass Through Trustee for the Pass Through Trusts then in existence created under the Pass
Through Trust Agreements referred to in Schedule II. If no Series B Equipment Notes are issued on the Closing Date, then, subject to compliance with the conditions set forth in Section 2.02 of the Participation Agreement and
Section 8.01(d) of the Intercreditor Agreement, as applicable, Company shall have the option to issue Series B Equipment Notes at any time after the Closing Date. Any Series B Equipment Notes issued after the


  
 Indenture and Security
Agreement (2020-1 EETC) 
 N626QX 
  

12 













 
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 such Schedule I may be amended in connection with any such issuance. Subject to compliance with the conditions set forth in Section 2.02 of the Participation Agreement and Section 8.01(c) or 8.01(d) of the Intercreditor
Agreement, as applicable, Company shall have the option after the Closing Date, at any time and from time to time (i) to issue one or more Series of Additional Series Equipment Notes under this Indenture (including, for the avoidance of
doubt, multiple issuances at the same or different times resulting in more than one Series of Additional Series Equipment Notes being outstanding at any time), (ii) to redeem all but not less than all of the Series B Equipment Notes (whether
issued on or after the Closing Date) (or all but not less than all of any Series of Additional Series Equipment Notes) pursuant to, and in accordance with, the provisions of Section 2.11(b) and to issue under this Indenture new Equipment Notes
with the same Series designation as, but with terms that may be the same as or different from those of, the redeemed Equipment Notes, and (iii) following the payment in full at maturity or otherwise of all but not less than all of the
Series B Equipment Notes (whether issued on or after the Closing Date) (or all but not less than all of any Series of Additional Series Equipment Notes), to issue new Equipment Notes with the same Series designation as, but with terms that may be
the same as or different from those of, such Equipment Notes that have been paid in full. If new Series B Equipment Notes or Additional Series Equipment Notes of any Series or new Additional Series Equipment Notes of any Series are issued after the
Closing Date in accordance with the immediately preceding sentence, such Equipment Notes shall be dated the date of original issuance thereof and shall have such maturities, principal amounts and interest rate as specified in an amendment to this
Indenture. The Equipment Notes shall be issued in registered form only. The Equipment Notes shall be issued in denominations of $1,000 and integral multiples thereof, except that one Equipment Note of each Series may be in an amount that is not an
integral multiple of $1,000. For the avoidance of doubt, if new “Series B Equipment Notes” or “Additional Series Equipment Notes” of any Series or new “Additional Series Equipment Note” of any Series are issued, in each
case under any Related Indenture, Company may, but shall not be required to, issue, as the case may be, new Series B Equipment Notes or Additional Series Equipment Notes of the same Series or new Additional Series Equipment Notes of the same Series,
in each case under this Indenture. 
 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, if issued, 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 Series B Equipment
Notes issued after the Closing Date, 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. Each Additional Series Equipment Note, if issued, shall be payable in installments or in a single payment as set forth in an amendment to this Indenture, and if payable in installments, such installments shall be
calculated as set forth in the preceding sentence. Notwithstanding the foregoing, the final payment made under each Equipment Note shall be in an amount sufficient to discharge in full the unpaid principal amount and all accrued and unpaid interest
on, and any other amounts due under, such Equipment Note. Each Equipment Note shall bear interest, payable on demand, at the Past Due Rate (and not at the Debt Rate) (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any principal amount and (to the extent permitted by applicable law) 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 therein or in this Indenture when due (whether at stated maturity, by acceleration or otherwise).
Notwithstanding anything to the contrary contained herein, if any date on which a payment hereunder or under any Equipment Note becomes due and payable is not a Business Day, then such payment shall not be made on such scheduled date but shall be
made on the next succeeding Business Day with the same force and effect as if made on such scheduled date, and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment from and after such
scheduled date. 
 The Equipment Notes shall be executed on behalf of Company by the manual or facsimile signature of one of its authorized
officers. Equipment Notes bearing the signatures of individuals who were at the time of execution the proper officers of Company shall bind Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Equipment Notes or did not hold such offices at the respective dates of such Equipment Notes. No Equipment Note shall be secured by or entitled to any benefit under this Indenture or be valid or obligatory for any
purposes unless there appears on such Equipment Note a certificate of authentication in the form provided herein executed by Loan Trustee by the manual signature of one of its authorized officers, and such certificate upon any Equipment Notes shall
be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder.

 Section 2.03 Method of Payment. The principal amount of, interest on, Make-Whole
Amount, if any, and, except to the extent expressly provided herein, all other amounts due under each Equipment Note or otherwise payable hereunder shall be payable by Company in Dollars by wire transfer of immediately available funds not later than
10:00 a.m. (New York City time) on the due date of payment to Loan Trustee at the Corporate Trust Office for distribution among Noteholders in the manner provided herein, and payment of such amount by Company to Loan Trustee shall be deemed to
satisfy Company’s obligation to make such payment. Company shall not have any responsibility for the distribution of such payment to any Noteholder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, Loan
Trustee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any Noteholder (with a copy to Company), all amounts paid by Company hereunder and under such Noteholder’s Equipment Note or Equipment Notes to such
Noteholder or a nominee therefor (including all amounts distributed pursuant to Article III) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, prior to 12:00 noon (New York City time) on the
due date of payment, to an account maintained by such Noteholder with a bank located in the continental United States the amount to be distributed to such Noteholder, for credit to the account of such Noteholder maintained at such bank;
provided that, in the event the Equipment Notes are not held by Subordination Agent on behalf of Pass Through Trustees, Loan Trustee shall, unless instructed by Company to use another method, pay such amounts by check mailed to
Noteholder’s address as it appears on the Equipment Note Register. If, after its receipt of funds at the place and prior to the time specified above in the immediately preceding sentence, Loan Trustee fails (other than as a result of a failure
of Noteholder to provide it with wire transfer instructions) to make any such payment required to be paid by wire transfer as provided in the immediately preceding sentence on the Business Day it receives such funds, Loan Trustee, in its individual
capacity and not as trustee, agrees to compensate such Noteholders for loss of use of funds at the Federal Funds Rate until such payment is made and Loan Trustee shall be entitled to any interest earned on such funds until such payment is made. Any
payment made hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to Loan Trustee for
cancellation. Notwithstanding any other provision of this Indenture to the contrary, Loan Trustee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which it is practicable for Loan
Trustee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 1:00 p.m. (New York City time) at the place of payment, 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 or 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, interest, 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 applicable law. Loan Trustee agrees to act as such withholding agent and 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 applicable law, any overdue Make-Whole Amount, if any, any overdue interest and any other overdue amounts thereunder) to the date of such payment; 

second, to the payment of Make-Whole Amount, if any, 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, neither the Company Guarantee Beneficiary nor any 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, the registration of transfers of Equipment Notes and a record of the dates and payments made with respect to the Equipment
Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of Loan Trustee. Loan Trustee is hereby appointed “Equipment Note
Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange or transfer such Equipment Note shall surrender such Equipment Note to Loan
Trustee at the Corporate Trust Office, together with a written request from the registered holder thereof for the issuance of a new Equipment Note of the same Series, specifying, in the case of a surrender for transfer, the name and address of the
new holder or holders. Upon surrender for registration of transfer of any Equipment Note and subject to satisfaction of Section 2.09, Company shall execute, and Loan Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Equipment Notes of an equal aggregate principal amount and of the same Series. At the option of Noteholder, Equipment Notes may be exchanged for other Equipment Notes of the same Series of any authorized
denominations of an equal aggregate principal amount, upon surrender of the Equipment Notes to be exchanged to Loan Trustee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, Company shall execute, and Loan
Trustee shall authenticate and deliver, the Equipment

Notes which Noteholder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this
Section 2.07 or under Section 2.08 or otherwise under this Indenture) shall be the valid obligations of Company evidencing the same respective obligations, and entitled to the same security and benefits under this Indenture, as the
Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer shall (if so required by Company or Loan Trustee) be duly endorsed or be accompanied by a written
instrument of transfer in form satisfactory to Loan Trustee, duly executed by Noteholder or such Noteholder’s attorney duly authorized in writing, and Company and Loan Trustee shall require evidence satisfactory to Company 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 and Equipment Note Registrar 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 this Indenture, the Related Indentures, the Participation Agreement, the Company Guarantee, the other Operative Documents and the Pass Through
Documents applicable to Noteholders or, in the case of each Related Indenture, Related Noteholders, and the Company Guarantee Beneficiary, 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) 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
Section 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.

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

 Section 3.06 Cooperation. Prior to making any distribution under this Article
III, Loan Trustee shall consult with Related Loan Trustees and the Company Guarantee Beneficiary to determine amounts payable with respect to the Related Secured Obligations. Loan Trustee shall cooperate with Related Loan Trustees and shall provide
such information as shall be reasonably requested by each Related Loan Trustee to enable such Related Loan Trustee to determine amounts distributable under Article III of its Related Indenture. 

Section 3.07 Securities Account. In furtherance of the provisions of Section 3.03, U.S. Bank agrees to act as an Eligible
Institution under this Indenture in accordance with the provisions of this Indenture (in such capacity, the “Securities Intermediary”). Except in its capacity as Loan Trustee, U.S. Bank waives any claim or lien against any Eligible
Account it may have, by operation of law or otherwise, for any amount owed to it by Company. The Securities Intermediary hereby agrees that, notwithstanding anything to the contrary in this Indenture, (i) any amounts to be held by Loan
Trustee pursuant to paragraph (ix) 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 Account, (ii) all such amounts, Permitted Investments and all other property acquired
with cash credited to the Securities Account will be credited to the Securities Account, (iii) all items of property (whether cash, investment property, Permitted Investments, other investments, securities, instruments or other property)
credited to the Securities Account will be treated as a “financial asset” under Article 8 of the NY UCC, (iv) its “securities intermediary’s jurisdiction” (as defined in
Section 8-110(e) of the NY UCC) with respect to the Securities Account is the State of New York, and (v) all securities, instruments and other property in order or registered form and credited
to the Securities Account shall be payable to or to the order of, or registered in the name of, the Securities Intermediary or shall be indorsed to the Securities Intermediary or in blank, and in no case whatsoever shall any financial asset credited
to the Securities Account be registered in the name of Company, payable to or to the order of Company or specially indorsed to Company except to the extent the foregoing have been specially endorsed by Company to the Securities Intermediary or in
blank. Loan Trustee agrees that it will hold (and will indicate clearly in its books and records that it holds) its “security entitlements” to the “financial assets” credited to the Securities Account in trust for the benefit of
Noteholders, each Indenture Indemnitee, each Related Indenture Indemnitee and the Company Guarantee Beneficiary as set forth in this Indenture. Company acknowledges that, by reason of Loan Trustee being the “entitlement holder” in respect
of the Securities Account as provided above, Loan Trustee shall have the sole right and discretion, subject

only to the terms of this Indenture, to give all “entitlement orders” (as defined in Section 8-102(a)(8) of the NY UCC) with respect to the
Securities Account and any and all financial assets and other property credited thereto to the exclusion of Company. If any Person asserts any Lien (including, without limitation, any writ, garnishment, judgment, warrant of attachment, execution or
similar process) against the Securities Account or any financial asset carried therein, the Securities Intermediary will promptly notify Loan Trustee and Company thereof.

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 Section 4.01(f), (g), (h) or (i) has occurred and is continuing, then and in

(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

or (C) exercise any other remedy of a secured party under the NY UCC (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 NY UCC 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 NY UCC or the Bankruptcy Code. 

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

Equipment Notes either have been accelerated pursuant to this Section 4.02 or have become due at maturity and Loan Trustee is entitled to exercise rights hereunder, at the request of Loan
Trustee, Company shall promptly execute and deliver to Loan Trustee such instruments of title and other documents as Loan Trustee reasonably deems necessary or advisable to enable Loan Trustee or an agent or representative designated by Loan
Trustee, at such time or times and place or places as Loan Trustee specifies, to obtain possession of all or any part of the Collateral to which Loan Trustee at the time is entitled hereunder. If Company for any reason fails to execute and deliver
such instruments and documents after such request by Loan Trustee, Loan Trustee may seek a judgment conferring on Loan Trustee the right to immediate possession and requiring Company to execute and deliver such instruments and documents to Loan
Trustee, to the entry of which judgment Company hereby specifically consents to the fullest extent it may lawfully do so. All actual and reasonable expenses of obtaining such judgment or of pursuing, searching for and taking such property shall,
until paid, be secured by the Lien of this Indenture. 
 (b) Loan Trustee shall give Company at least 30 days’ prior written notice of
any public sale or of the date on or after which any private sale will be held, which notice Company hereby agrees to the extent permitted by applicable law is reasonable notice. Any Noteholder or Noteholders shall be entitled to bid for and become
the purchaser of any Collateral offered for sale pursuant to this Section 4.02 and to credit against the purchase price bid at such sale by such Noteholders all or any part of the unpaid amounts owing to such Noteholders under the Operative
Documents and secured by the Lien of this Indenture (but only to the extent that such purchase price would have been paid to such Noteholders pursuant to Article III if such purchase price were paid in cash and the foregoing provision of this
Section 4.02(b) were not given effect). Loan Trustee may exercise such right without possession or production of the Equipment Notes or proof of ownership thereof, and as a representative of Noteholders may exercise such right without notice to
Noteholders as party to any suit or proceeding relating to the foreclosure of any Collateral. Company may also bid for and become the purchaser of any Collateral offered for sale pursuant to this Section 4.02. 

(c) To the extent permitted by applicable law, while an Event of Default has occurred and is continuing, Company irrevocably appoints Loan
Trustee the true and 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 U.S. 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. Subject to Section 5.03, 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 or the Equipment Notes or otherwise, or for the appointment of a receiver or for the enforcement of any other remedy
under this Indenture or the Equipment Notes or otherwise, unless: 
 (1) such Noteholder previously shall have given written
notice to Loan Trustee of a continuing Event of Default; 
 (2) a Majority in Interest of Noteholders shall have requested
Loan Trustee in writing to institute such action, suit or proceeding and shall have offered to Loan Trustee indemnity as provided in Section 5.03;

 (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 herein, 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 Equipment Notes of such Series to (i) surrender, impair, waive, affect, disturb or prejudice any Collateral, or the Lien of this 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 or the Equipment
Notes of such Series, 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 actual 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


  
 Indenture and Security

 N626QX 
  

45 













 
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. In acting pursuant to the immediately preceding sentence, 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 a Trust Officer 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 this 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.

 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).

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 (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by Company or a Permitted Lessee, as the case may be, upon discovery thereof or (ii) to the extent Company (or, if a Lease

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 (or any Permitted Lessee) to

Aircraft is then registered). Company shall also have the right to operate the Aircraft without having on board the original registration certificate or airworthiness certificate in the event that either or both such certificates disappear from the
Aircraft, but only to the extent permitted by Exemption No. 5318 of the regulations of the FAA or other similar exemption. 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 or any other circumstances
beyond the reasonable control of Company (or any Permitted Lessee) and Company (or any Permitted Lessee) is using its good faith efforts to remove the Aircraft from such area as promptly as practicable.

(2) the civil aviation authority of Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Spain, Switzerland or the United Kingdom, or (3) the

and repair required to be maintained by the terms hereof 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 (v) during temporary
periods of storage, during maintenance, testing or modification permitted hereunder, (w) during periods of grounding by applicable governmental authorities, (x) during periods when the FAA or such other aviation authority has
revoked or suspended the airworthiness certificates for aircraft of the same manufacturer and model as the Aircraft, (y) with respect to immaterial or non-recurring violations with respect to which
corrective measures are taken promptly upon discovery thereof and (z) to the extent Company or any Permitted Lessee is promptly contesting in good faith the validity or application of any law or requirement relating to any such
certification in any manner which does not create a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any Engine or the interest of Loan Trustee therein or any material risk of criminal liability or material civil penalty
against Loan Trustee) 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)). 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. If not prevented by applicable law or regulations or by any government, Company agrees to affix as promptly as practicable after the Closing Date and thereafter to maintain in the flight deck of the Aircraft, in a
clearly visible location, and 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). Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframe or Engines.

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 hereunder is valid and enforceable under the laws of such country, (B) after giving effect to such change in registration, the Lien of this Indenture shall continue as a valid 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

N626QX 













 
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): 
 (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.

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

will deliver a paper copy of any item referred to in clause (i) and clause (ii) above if Loan Trustee so requests. 

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

 (a) Replacement of Parts. Company shall (or shall cause a Permitted Lessee to) 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 (or cause to be removed) in the ordinary course of maintenance, service, repair,
overhaul or testing, any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or 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 good operating condition. 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 instruments reasonably requested by Company
confirming the release of any such replaced Part from the Lien of this Indenture. 

  
 61 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 (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 Airframe or such Engine 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 (or causes to be replaced) 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). Notwithstanding the foregoing, from time to time, Company or any Permitted Lessee may temporarily install on the Airframe for a
period of up to 180 days, in lieu of an auxiliary power unit or landing gear that has been removed and delivered to an organization for maintenance, service, repair, overhaul or testing (which removed auxiliary power unit or landing gear, as the
case may be, shall remain subject to the Lien of this Indenture no matter where located), an auxiliary power unit or landing gear, as the case may be, supplied to Company or such Permitted Lessee by such organization, which need not satisfy the
requirements for a replacement Part specified above, and neither the Loan Trustee nor the Noteholders will acquire or claim, as against such supplying organization, any right, title or interest in such supplied auxiliary power unit or landing gear,
as the case may be, as the result of their installation on the Airframe. 
 (c) Alterations, Modifications and Additions. Company
will, or will cause a Permitted Lessee to, 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; except for (i) immaterial and non-recurring violations with respect to which corrective measures are being
taken promptly by Company (or, if a Lease is then in effect, any Permitted Lessee) upon discovery thereof and (ii) any law, rule, regulation or order the validity or application of which is 

  
 62 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 
being contested in good faith by Company (or, if a Lease is then in effect, any Permitted Lessee) in any manner which 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 (or such Permitted Lessee) deems obsolete or no longer suitable or appropriate for use on the Airframe or any Engine. For the avoidance of doubt, Company may make alterations in the passenger configuration of the Aircraft and such
alterations shall not be subject to the immediately preceding sentence. All Parts incorporated or installed in or attached or added to the Airframe or any Engine as the result of such alteration, modification or addition shall, without further act,
be subject to the Lien of this Indenture. Notwithstanding the foregoing, Company (or any Permitted Lessee) may, at any time, remove any Part from the Airframe or any Engine if such Part: (i) is in addition to, and not in replacement of
or substitution for, any Part originally incorporated or installed in or attached to the Airframe or such Engine at the time of delivery thereof to Company or any Part in replacement of, or substitution for, any such Part, (ii) is not
required to be incorporated or installed in or attached or added to the Airframe or such Engine pursuant to the first sentence of this Section 7.04(c) and (iii) can be removed from the Airframe or such Engine without materially
diminishing 
 the value or utility required to be maintained by the terms of this Indenture that the Airframe or such Engine would have had 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 instruments reasonably requested by Company
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.

N626QX 













 (d) Substitution of Engines. Company shall have the right at its option at any time
and from time to 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. 
 (e) Substitution
of Airframe. Company shall have the right at its option at any time and from time to time, on at least 10 Business Days’ prior written notice to Loan Trustee, to substitute a Substitute Airframe, free and clear of all Liens (other than
Permitted Liens), for the Airframe so long as (i) no Event of Default shall have occurred and be continuing at the time of substitution, (ii) the Substitute Airframe has a date of manufacture no earlier than one year prior to
the date of manufacture of the Airframe subject to the Lien of this Indenture on the Closing Date (each such date of manufacture, in each case, to be deemed to be the date of original delivery of the applicable airframe to a customer by the
Manufacturer) and (iii) the Substitute Airframe has a MCMV (as defined below) at least equal to the MCMV of the Airframe being replaced by the Substitute Airframe (assuming that the Airframe had been maintained in accordance with this
Indenture), in each case as determined by a desktop appraisal dated as of a date within the 60-day period prior to the substitution performed by an Appraiser selected by Company. “MCMV” is the
“current market value” (as defined by the International Society of Transport Aircraft Trading or any successor organization) adjusted for the maintenance status of the Substitute Airframe and the Airframe being replaced by the Substitute
Airframe, as applicable, such maintenance status to be based upon maintenance data provided by Company to the applicable Appraiser with respect to the Substitute Airframe and such Airframe as of the same date within the 60-day period prior to the substitution for both the Substitute Airframe and such Airframe. 
 Prior to or
at the time of any substitution under this Section 7.04(e), Company will (A) cause an Indenture Supplement covering such Substitute Airframe 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 may then be registered, (B) cause the sale of such Substitute Airframe to Company (if occurring after
February 28, 2006 and if the seller of such Substitute Airframe 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 Substitute Airframe to be registered on the International Registry as a sale or an International Interest, respectively; provided that if the seller of such Substitute Airframe is not
situated in a country that has ratified the Cape Town Convention, Company will use its reasonable 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 such Substitute Airframe 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 may then be registered, (D) furnish Loan Trustee with an opinion of counsel to Company (which may be internal counsel of Company) addressed to Loan Trustee to the effect that upon such substitution, such Substitute
Airframe 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 evidence of compliance with the insurance provisions of Section 7.06 with respect
to such Substitute Airframe, (F) furnish Loan Trustee with a copy of the original bill of sale in respect of such Substitute Airframe and (G) furnish Loan Trustee with an opinion of counsel to Company (which may be internal counsel
of Company) in form reasonably satisfactory to Loan Trustee to the effect that Loan Trustee will be entitled to the benefits of Section 1110 with respect to the Substitute 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 opinion of counsel to Company delivered pursuant to Section 3.01 of the Participation Agreement on the Closing Date and such other
qualifications and assumptions as shall at the time be customary in opinions rendered in comparable circumstances. 
 In the case of the
Substitute Airframe subjected to the Lien of this Indenture under this Section 7.04(e), promptly upon the recordation of the Indenture Supplement covering such Substitute Airframe pursuant to the Transportation Code (or pursuant to the
applicable law of such other jurisdiction in which such Substitute Airframe is registered), Company will cause to be delivered to Loan Trustee a favorable opinion of aviation law counsel to Company (which may be internal counsel of Company)
addressed to Loan Trustee as to the due registration of the aircraft to which the Substitute Airframe is part and 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 Substitute Airframe to Company (if occurring after February 28, 2006 and if the seller of such Substitute Airframe is “situated in” a country that has ratified the Cape Town Convention) and
of the International Interests created pursuant to the Indenture Supplement with respect to such Substitute Airframe and the validity and perfection of the security interest in the Substitute Airframe granted to Loan Trustee under this Indenture.

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 if the seller of such Replacement Engine is “situated in” a country that has ratified the Cape Town Convention) and of the International Interest created pursuant
to the Indenture Supplement with respect to such Replacement Engine and the validity and perfection of the security interest in the Replacement Engine granted to Loan Trustee under this Indenture. For all purposes hereof, upon the attachment of the
Lien of this Indenture thereto, the Replacement Engine shall become part of the Collateral and shall be deemed an “Engine” as defined herein. Upon compliance with clauses (i) through (vii) of the first sentence of this
paragraph, Loan Trustee shall execute and deliver to Company instruments reasonably requested by Company releasing such replaced Engine, any proceeds (including, without limitation, insurance proceeds) 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 its actual and reasonable out-of-pocket costs and expenses that shall not exceed the amounts required to be paid by Company 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 its actual and reasonable out-of-pocket costs and expenses shall be paid over to, or
retained by, Company; provided that Company has fully performed its obligations under Section 7.05(b) with respect to the Event of Loss for which such payments are made. 

(d) Requisition for Use by the Government of the Airframe and the Engines Installed Thereon. In the event of the requisition for use or
hire by any government (it being acknowledged that the use of the Airframe or any Engine pursuant to the CRAF Program does not constitute such a requisition 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.

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 (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 subsection (a), and subject to the rights of Company to establish and
maintain self-insurance in the manner and to the extent specified in Section 7.06(c), Company will carry, or cause to be carried, at no expense to Loan Trustee, aircraft liability insurance (including, but not limited to, bodily injury,
personal injury and property damage liability, exclusive of manufacturer’s product liability insurance) and contractual liability insurance with respect to the Aircraft (A) in amounts per occurrence that are not less than the
aircraft liability insurance applicable to similar aircraft and engines in Company’s fleet on which Company carries insurance (or, in the case of a lease to a Permitted Lessee, in such Permitted Lessee’s fleet on which such Permitted
Lessee carries insurance); provided that such liability insurance (including 

  
 72 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 
self-insurance specified in Section 7.06(c)) 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, (B) of the type usually carried by corporations engaged in the same or similar business, similarly situated with Company or such Permitted Lessee, as the case may be, and owning or operating
similar aircraft and engines and covering risks of the kind customarily insured against by Company or such Permitted Lessee, as the case may be, and (C) that is maintained in effect with insurers of recognized responsibility;
provided that Company will carry, or cause to be carried, at no expense to Loan Trustee, aircraft liability war risk and allied perils insurance if and to the extent the same is maintained by Company or such Permitted Lessee, as the case may
be, with respect to other similar aircraft operated by Company or such Permitted Lessee, as the case may be, on the same or similar routes. 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 (A) name Loan Trustee, Subordination Agent, each Pass Through Trustee and each Liquidity Provider as their Interests (as defined below in this Section 7.06) may appear, as
additional insureds (the “Additional Insureds”), (B) subject to the conditions of clause (C) below, provide that, in respect of the interests of the Additional Insureds in such policies, the insurance shall not be
invalidated by any action or inaction of Company (or any Permitted Lessee) and shall insure the Additional Insureds’ Interests as they appear, regardless of any breach or violation of any warranty, declaration or condition contained in such
policies by Company (or any Permitted Lessee), (C) provide that, except to the extent not provided for by the war risk and allied perils insurance provider (in which case the last sentence of this Section 7.06(a)(i) applies), if
such insurance is canceled for any reason whatsoever, or if any change is made in the policy that materially reduces the amount of insurance or the coverage certified in the insurance report delivered on the Closing Date to Loan Trustee and each
Liquidity Provider, or if such insurance is allowed to lapse for nonpayment of premium, such cancellation, change or lapse shall not be effective as to any Additional Insured for 30 days (seven days, or such other period as is customarily available
in the industry, in the case of any war risk or allied perils coverage) after receipt by such Additional Insured of written notice from such insurers of such cancellation, change or lapse, (D) provide that the Additional Insureds shall
have no obligation or liability for premiums, commissions, assessments or calls in connection with such insurance, (E) provide that the insurers shall waive any rights of (1) set-off,
counterclaim or any other deduction, whether by attachment or otherwise, in respect of any liability of the Additional Insureds to the extent of any moneys due to the Additional Insureds and (2) subrogation against the Additional
Insureds to the extent that Company or, if applicable, such Permitted Lessee has waived its rights by its agreements to indemnify the Additional Insureds pursuant to the Operative Documents or, if applicable, pursuant to the lease to such Permitted
Lessee, (F) be

primary without right of contribution from any other insurance that may be carried by each Additional Insured with respect to its Interests as such in the Aircraft and (G) expressly
provide that all of the provisions thereof, except the limits of liability, shall operate in the same manner as if there were a separate policy covering each insured. “Interests” as used in this Section 7.06(a) and in
Section 7.06(b) with respect to any Person means the interests of such Person in the transactions contemplated by the Operative Documents. In the case of a lease or contract with any government in respect of the Aircraft, the Airframe or any
Engine, or in the case of any requisition for use of the Aircraft, the Airframe or any Engine by any government, a valid agreement by such government to indemnify Company, or an insurance policy issued by such government, against any of the risks
that Company is required hereunder to insure against shall be considered adequate insurance for purposes of this Section 7.06(a) to the extent of the risks (and in the amounts) that are the subject of such indemnification or insurance. To the
extent that the war risk and allied perils insurance provider does not provide for provision of direct notice to each Additional Insured of cancellation, change or lapse in the insurance required hereunder, Company hereby agrees that upon receipt of
notice of any thereof from such insurance provider it shall give each Additional Insured immediate notice of each cancellation or lapse of, or material 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 in operation, Company may
carry or cause to be carried as to such non-operating 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(c), insurance otherwise conforming with the provisions of said clause (i) except that: (A) the amounts of coverage shall not be required to exceed the amounts of airline liability insurance
from time to time applicable to airframes or engines owned or leased by Company (or, in the case of a lease to a Permitted Lessee, such Permitted Lessee) of the same type as such non-operating Airframe or
Engine and that are on the ground and not in operation and (B) the scope of the risks covered and the type of insurance shall be the same as from time to time shall be applicable to airframes or engines owned or leased by Company (or
such Permitted Lessee) of the same type as such non-operating Airframe or Engine and that are on the ground and not in operation. 

(b) Insurance Against Loss or Damage to Aircraft. 

(i) Except as provided in clause (ii) of this subsection (b), and subject to the rights of Company to establish and
maintain self-insurance in the manner and to the extent specified in Section 7.06(c), Company shall maintain, or cause to be maintained, in effect with insurers of recognized responsibility, at no expense
to Loan Trustee, all-risk aircraft hull insurance covering the Aircraft and all-risk 

  
 74 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 
coverage with respect to any Engines or Parts while removed from the Aircraft (including, without limitation, war risk and allied perils insurance if and to the extent the same is maintained by
Company (or, in the case of a lease to a Permitted Lessee, such Permitted Lessee) with respect to other aircraft operated by Company or such Permitted Lessee, as the case may be, on the same or similar routes) that is of the type usually carried by
corporations engaged in the same or similar business and similarly situated with Company or such Permitted Lessee, as the case may be; 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 outstanding principal amount of the Equipment Notes from time to time and
(B) such insurance need not cover an Engine while attached to an airframe not owned, leased or operated by Company, provided that such Engine is covered by a separate policy of insurance. Any policies carried in accordance with this
Section 7.06(b) and any policies taken out in substitution or replacement for any such policies shall (A) provide that (I) 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 (II) any insurance proceeds in excess of the Insurance Threshold up to the amount of the Loan Amount for any loss or damage
to the Aircraft (or Engines) not constituting an Event of Loss with respect to the Aircraft (or Engines), shall be paid to Loan Trustee as long as this Indenture shall not have been discharged, and that all other amounts shall be payable to Company
or such Permitted Lessee, unless the insurer shall have 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 the amount of the Loan Amount shall be payable to
Loan Trustee, (B) subject to the conditions of clause (C) below, provide that, in respect of the interests of the Additional Insureds in such policies, the insurance shall not be invalidated by any action or inaction of Company (or
any Permitted Lessee) and shall insure the Additional Insureds’ Interests as they appear, regardless of any breach or violation of any warranty, declaration or condition contained in such policies by Company (or any Permitted Lessee),
(C) provide that, except to the extent not provided by the war risk and allied perils insurance provider, if such insurance is canceled for any reason whatsoever, or if any change is made in the policy that materially reduces the amount
of such insurance or the coverage certified in the insurance report delivered on the Closing 

  
 75 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 
Date to Loan Trustee and each Liquidity Provider, or if such insurance is allowed to lapse for nonpayment of premium, such cancellation, change or lapse shall not be effective as to the
Additional Insureds for 30 days (seven days, or such other period as is customarily available in the industry, in the case of war risk or allied perils coverage) after receipt by the Additional Insureds of written notice from such insurers of such
cancellation, change or lapse, (D) provide that the Additional Insureds shall have no obligation or liability for premiums, commissions, assessments or calls in connection with such insurance, (E) provide that the insurers
shall waive rights of (1) set-off, counterclaim or any other deduction, whether by attachment or otherwise, in respect of any liability of the Additional Insureds to the extent of any moneys due to
the Additional Insureds and (2) subrogation against the Additional Insureds to the extent Company or, if applicable, such Permitted Lessee has waived its rights by its agreement to indemnify the Additional Insureds pursuant to the
Operative Documents or, if applicable, pursuant to the lease to such Permitted Lessee, and (F) be primary without right of contribution from any other insurance that may be carried by any Additional Insured with respect to its Interests
as such in the Aircraft. In the case of a lease or contract with any government in respect of the Aircraft, the Airframe or any Engine, or in the case of any requisition for use of the Aircraft, the Airframe or any Engine by any government, a valid
agreement by such government to indemnify Company, or an insurance policy issued by such government, against any risks which Company is required hereunder to insure against shall be considered adequate insurance for purposes of this
Section 7.06(b) to the extent of the risks (and in the amounts) that are the subject of such indemnification or insurance. To the extent that the war risk and allied perils insurance provider does not provide for provision of direct notice to
each Additional Insured of cancellation, change or lapse in the insurance required hereunder, Company hereby agrees that upon receipt of notice of any thereof from such insurance provider it shall give each Additional Insured immediate notice of
each cancellation or lapse of, or material change to, such insurance. 
 (ii) During any period that the Airframe or an
Engine is on the ground and not in operation, Company may carry or cause to be carried as to such non-operating 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(c), insurance otherwise conforming with the provisions of said clause (i) except that the scope of the risks covered and the type of insurance shall be the same as from time to time
applicable to airframes or engines owned or leased by Company (or, if a lease to a Permitted Lessee is then in effect, by such Permitted Lessee) of the same type as such non-operating Airframe or Engine and
that are on the ground and not in operation; provided that, subject to self-insurance to the extent permitted by Section 7.06(c), Company (or such Permitted Lessee) shall maintain insurance against risk of loss or damage to such non-operating Airframe in an amount at least equal to 110% of the aggregate outstanding principal amount of the Equipment Notes during such period that such Airframe is on the ground and not in operation. 

  
 76 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 (c) Self-Insurance. Company may from time to time self-insure, by way of deductible,
self-insured retention, premium adjustment or franchise or otherwise (including, with respect to insurance maintained pursuant to Section 7.06(a) or Section 7.06(b), insuring for a maximum amount that is less than the amounts set forth in
Section 7.06(a) and Section 7.06(b)), the risks required to be insured against pursuant to Section 7.06(a) and Section 7.06(b), 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% of the average aggregate insurable value (for the preceding policy year) of all
aircraft (including, without limitation, the Aircraft) on which Company and its Affiliates carry insurance, unless Company’s independent insurance broker shall certify that the standard among major United States airlines is a higher level of
self-insurance, in which case Company may self-insure the Aircraft to such higher level. In addition to the foregoing right to self-insure, Company may self-insure to the extent of (1) any deductible per occurrence that, in the case of
the Aircraft, is not in excess of the amount customarily allowed as a deductible in the industry or is required to facilitate claims handling or (2) any applicable mandatory minimum per aircraft (or if applicable per annum or other
period) hull or liability insurance deductibles customarily imposed by the aircraft or hull liability insurers in the airline industry. 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 this
Section 7.06(c)) shall be considered adequate insurance for purposes of this Section 7.06. 
 (d) Application of Insurance
Payments. All losses will be adjusted by Company with the insurers. As between Loan Trustee and Company, it is agreed that all insurance payments received under policies required to be maintained by Company hereunder, exclusive of any payments
received in excess of the Loan Amount, as the result of the occurrence of an Event of Loss with respect to the Airframe or an Engine will be applied as follows: 

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

  
 77 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 (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 shall not
exceed the amounts required to be paid by Company pursuant to Section 2.10 hereof shall be applied (A) 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 (B) the balance, if any, of such payment remaining thereafter will be paid over to, or retained by, Company or its designee; and 

(iii) if such payments are received with respect to an Engine with regard to which an Event of Loss contemplated by
Section 7.05(b) has occurred, 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 or its designee; provided that Company shall have performed
its obligations under Section 7.05(b) with respect to the Event of Loss for which such payments are made. 
 In all events,
(x) the insurance payment of any property damage or loss with respect to property other than the Airframe or any Engine received under policies maintained by Company (or, if a lease to a Permitted Lessee is then in effect, by such
Permitted Lessee), and (y) the insurance payment for any loss or damage to the Aircraft in excess of the Loan Amount, shall be paid to Company (or such Permitted Lessee) or its designee. 

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 or, if a lease to a Permitted Lessee is then in effect, such Permitted Lessee) for repairs or for replacement property in accordance with the terms of Section 7.02 and
Section 7.04, and any balance remaining after compliance with such Sections with respect to such loss or damage shall be paid to Company (or such Permitted Lessee) or its designee. Any amount referred to in the preceding sentence or in clause
(i) or (iii) of the second preceding paragraph 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 or retention an
Event of Default or Payment Default shall have occurred and be continuing, but, subject to Section 5.06, shall be paid over to or held by Loan Trustee as security for the obligations of Company under this Indenture and the other Operative
Documents and shall be invested pursuant to Section 5.06 unless and until such amount is applied, at the option of Loan Trustee, to Company’s obligations under this Indenture and the other Operative Documents as and when due, it being
understood that any such application shall be made to such obligations of Company as Loan Trustee may determine in its sole discretion. Loan Trustee shall give Company prompt written notice of any such application, but the failure to so notify
Company shall not in any way affect the rights of Loan Trustee hereunder. At such time as there shall not be continuing any such 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(d). 

  
 78 

Indenture and Security Agreement (2020-1 EETC) 

N626QX 













 (e) Reports, Etc. On or before the Closing Date and annually upon renewal of
Company’s insurance coverage, Company will furnish (or cause to be furnished) to Loan Trustee and each Liquidity Provider one or more reports signed by a firm of independent aircraft insurance brokers appointed by or with the consent of Company
(which firm may be in the regular employ of Company), stating the opinion of such firm that the commercial hull and liability insurance then carried and maintained on the Aircraft complies with the terms hereof; provided that all information
contained in such report shall be Confidential Information and shall be treated by Loan Trustee, each Liquidity Provider and each of their affiliates and officers, directors, agents and employees in accordance with the provisions of
Section 10.16. Company will use commercially reasonable efforts to cause such firm to agree to advise Loan Trustee and each Liquidity Provider in writing 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 use commercially reasonable efforts to cause such firm to advise Loan Trustee and each Liquidity Provider in writing as promptly as practicable
after such firm acquires knowledge that an interruption of any insurance carried and maintained on the Aircraft pursuant to this Section 7.06 will occur. Such information may only be provided to other Persons in accordance with
Section 10.16. 
 (f) Salvage Rights. All salvage rights to the Airframe and each Engine shall remain with Company’s
insurers or the applicable Permitted Lessee’s insurers, as the case may be, at all times, and any insurance policies of Loan Trustee insuring the Airframe or any Engine shall provide for a release to Company or such Permitted Lessee, as the
case may be, of any and all salvage rights in and to the Airframe or any Engine. 
 (g) Right to Pay Premium. In the event of
cancellation of any insurance required to be maintained hereunder due to the nonpayment of premiums, Loan Trustee shall have the option, in its sole discretion, to pay any such premium in respect to the Aircraft that is due in respect of the
coverage pursuant to this Indenture and to maintain such coverage, as Loan Trustee may require, until the scheduled expiry date of such insurance and, in such event, Company shall, upon demand, reimburse Loan Trustee for amounts so paid by it.

N626QX 













 (h) Insurance for Own Account. Nothing in this Section 7.06 shall limit or
prohibit (i) Company from maintaining the policies of insurance required pursuant to this Section 7.06 with higher limits than those specified herein or (ii) Loan Trustee or Company from obtaining insurance for its own
account, and at its sole expense, with respect to the Airframe or any Engine (and any proceeds payable under such insurance shall be payable as provided in the insurance policy relating thereto); provided that no such insurance may be
obtained which would limit or otherwise adversely affect the coverage or amounts payable under, or increase the premiums for, any insurance required to be maintained pursuant to this Section 7.06 or any other insurance maintained by Company (or
any Permitted Lessee) with respect to the Aircraft or any other aircraft in Company’s (or such Permitted Lessee’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.

N626QX 













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

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

 Section 8.02 Appointment of Additional and Separate Trustees. 

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

 (b) No additional or separate trustee shall be entitled to exercise any of the rights,
powers, duties and obligations conferred upon Loan Trustee in respect of the custody, investment and payment of monies and all monies received by any such additional or separate trustee from or constituting part of the Collateral or otherwise
payable under any Operative Documents to Loan Trustee shall be promptly paid over by it to Loan Trustee. All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by
Loan Trustee and such additional or separate trustee jointly except to the extent that applicable law of any jurisdiction in which any particular act is to be performed renders Loan Trustee incompetent or unqualified to perform such act, in which
event such rights, powers, duties and obligations (including the holding of title to all or part of the Collateral in any such jurisdiction) shall be exercised and performed by such additional or separate trustee. No additional or separate trustee
shall take any discretionary action except on the instructions of Loan Trustee or a Majority in Interest of Noteholders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that
Loan Trustee shall be liable for the consequences of its lack of reasonable care in selecting, and Loan Trustee’s own actions in acting with, any additional or separate trustee. Each additional or separate trustee appointed pursuant to this
Section 8.02 shall be subject to, and shall have the benefit of Articles IV, V, VI, VIII, IX and X insofar as they apply to Loan Trustee. The powers of any additional or separate trustee appointed pursuant to this Section 8.02 shall not in
any case exceed those of Loan Trustee. 
 (c) If at any time Loan Trustee deems it no longer necessary or desirable or in the event that Loan
Trustee has been requested to do so in writing by a Majority in Interest of Noteholders, Loan Trustee and, upon the written request of Loan Trustee, 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.
