 SECTION 2.1. Agreement to Terms of Subordination; Payments from Monies Received Only. (a) Each Trustee
hereby acknowledges and agrees to the terms of subordination and distribution set forth in this Agreement in respect of each Class of Certificates and agrees to enforce such provisions and cause all payments in respect of the Equipment Notes
held by the Subordination Agent to be applied in accordance with the terms of this Agreement. In addition, each Trustee hereby agrees to cause the Equipment Notes purchased by the related Trust to be registered in the name of the Subordination Agent
or its nominee, as agent and trustee for such Trustee, to be held in trust by the Subordination Agent solely for the purpose of facilitating the enforcement of the subordination and other provisions of this Agreement. 

(b) Except as otherwise expressly provided in the next succeeding sentence of this Section 2.1(b), all payments to be made by the
Subordination Agent hereunder shall be made only from amounts received by it that constitute Scheduled Payments, Special Payments, payments under Section 8.1 of the Participation Agreements, or payments under Section 6 of the Note Purchase
Agreement and only to the extent that the Subordination Agent shall have received sufficient income or proceeds therefrom to enable it to make such payments in accordance with the terms hereof. Each of the Trustees and the Subordination Agent hereby
agrees and, as provided in each Trust Agreement, each Certificateholder, by its acceptance of a Certificate, has agreed to look solely to such amounts to the extent available for distribution to it as provided in this Agreement and that none of the
Trustees, the Loan Trustees and the Subordination Agent is personally liable to any of them for any amounts payable or any liability under this Agreement, any Trust Agreement, or such Certificate, except (in the case of the Subordination Agent) as

and the Certificateholders and (ii) as a sub-account in the Collection Account, the Special Payments Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the
benefit of the Trustees and the Certificateholders. The Special Payments Account and the Collection Account, constitute the “Trust Accounts” hereunder. Without limiting the foregoing, all monies credited to the Trust Accounts shall
be, and shall remain, the property of the relevant Trust(s). 
 (b) Funds on deposit in the Trust Accounts shall be invested and reinvested
by the Subordination Agent in Eligible Investments selected by the Subordination Agent if such investments are reasonably available and have maturities no later than the earlier of (i) 90 days following the date of such investment and (ii) the

Collection Account are to be applied and any losses shall be charged against the principal amount invested, in each case net of the Subordination Agent’s reasonable fees and expenses in making such investments. The Subordination Agent shall not

 ARTICLE IV 

EXERCISE OF REMEDIES 
 SECTION
4.1. Directions from the Controlling Party. (a) (i) Following the occurrence and during the continuation of an Indenture Default under any Indenture, the Controlling Party shall direct the Subordination Agent, as the holder of Equipment
Notes issued under such Indenture, which in turn shall direct the Loan Trustee under such Indenture, in the exercise of remedies available to the holder of such Equipment Notes, including, without limitation, the ability to vote all such Equipment
Notes held by the Subordination Agent in favor of Accelerating such Equipment Notes in accordance with the provisions of such Indenture. Subject to Section 4.1(a)(iii), if the Equipment Notes issued pursuant to any Indenture and held by the
Subordination Agent have been Accelerated following an Indenture Default with respect thereto, the Controlling Party may direct the Subordination Agent to sell, assign, contract to sell or otherwise dispose of and deliver all (but not less than all)
of such Equipment Notes or all or any portion of the Collateral under such Indenture to any Person at public or private sale, at any location at the option of the Controlling Party; provided that, in each case, such sale, assignment or other
disposition shall be conducted in a commercially reasonable manner and in accordance with applicable law, including Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof) and, to the extent a Bankruptcy Event has occurred and is continuing, the Bankruptcy Code. If all or any portion of the Collateral is sold or
otherwise disposed of following an Indenture Default, no break-up fees or other fees (excluding third-party broker fees) or similar amounts may be paid to any buyer, potential buyer or other Person from the
proceeds of such sale or other disposition. 
 (ii) Following the occurrence and during the continuation of an Indenture Default under any
Indenture, in the exercise of remedies pursuant to such Indenture, the Loan Trustee under such Indenture may be directed to lease the related Aircraft to any Person (including Sun Country) so long as the Loan Trustee in doing so acts in a
“commercially reasonable” manner within the meaning of Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof). 
 (iii) Notwithstanding the foregoing, so long as any Certificates remain Outstanding,
during the period ending on the date which is nine months after the earlier of (x) the Acceleration of the Equipment Notes issued pursuant to any Indenture and (y) the occurrence of a Bankruptcy Event, without the consent of each Trustee,
no Aircraft subject to the Lien of such Indenture or such Equipment Notes may be sold if the net proceeds from such sale would be less than the Minimum Sale Price for such Aircraft or such Equipment Notes. 

(iv) Upon the occurrence and continuation of an Indenture Default under any Indenture, the Subordination Agent will obtain three desktop
appraisals from the Appraisers selected by the Controlling Party setting forth the current market value, current lease rate and distressed value (in each case, as defined by the International Society of Transport Aircraft Trading or any successor
organization) of the Aircraft subject to such Indenture (each such appraisal, an “Appraisal” and the current market value appraisals being referred to herein as the “Post-Default Appraisals”). For so
long as any Indenture Default shall be continuing under any 

  
 22 

 
Indenture, and without limiting the right of the Controlling Party to request more frequent Appraisals, the Subordination Agent will obtain updated Appraisals on the date that
is 364 days from the date of the most recent Appraisal (or if a Bankruptcy Event shall have occurred and is continuing, on the date that is 180 days from the date of the most recent Appraisal) and will, acting on behalf of each
Trustee, post such Appraisals on website accessible to the Certificateholders or make such other commercially reasonable efforts as the Subordination Agent may deem appropriate to make such Appraisals available to all Certificateholders. 

(b) Following the occurrence and during the continuance of an Indenture Default under any Indenture, the Controlling Party shall take such
actions as it may reasonably deem most effectual to complete the sale or other disposition of the relevant Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment, contract to sell or other disposition, the Controlling Party may
maintain or cause the Subordination Agent to maintain possession of such Equipment Notes and continue to apply monies received in respect of such Equipment Notes in accordance with Article III hereof. In addition, in lieu of such sale, assignment,
contract to sell or other disposition, or in lieu of such maintenance of possession, the Controlling Party may, subject to the terms and conditions of the related Indenture, instruct the Loan Trustee under such Indenture to foreclose on the Lien on
the related Aircraft or to take any other remedial action permitted under such Indenture or under any applicable law, including . Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof) and, to the extent a Bankruptcy Event has occurred and is continuing, the Bankruptcy Code. 

(c) If following a Bankruptcy Event and during the pendency thereof, the Controlling Party receives a proposal from or on behalf of Sun
Country to restructure the financing of any one or more of the Aircraft, the Controlling Party shall promptly thereafter give the Subordination Agent and each Trustee notice of the material economic terms and conditions of such restructuring
proposal whereupon the Subordination Agent acting on behalf of each Trustee shall endeavor using reasonable commercial efforts to make such terms and conditions of such restructuring proposal available to all Certificateholders. Thereafter, neither
the Subordination Agent nor any Trustee, whether acting on instructions of the Controlling Party or otherwise, may, without the consent of each Trustee, enter into any term sheet, stipulation or other agreement (whether in the form of an adequate
protection stipulation, an extension under Section 1110(b) of the Bankruptcy Code or otherwise) to effect any such restructuring proposal with or on behalf of Sun Country unless and until the material economic terms and conditions of such
restructuring shall have been made available to all Certificateholders for a period of not less than 15 calendar days (except that such requirement shall not apply to any such term sheet, stipulation or other agreement that is entered into on or
prior to the expiry of the 60-Day Period and that is effective for a period not longer than three months from the expiry of the 60-Day Period). In the event that any
Class B Certificateholder or Additional Certificateholder gives irrevocable notice of the exercise of its right to purchase all (but not less than all) of the Class of Certificates represented by the then Controlling Party pursuant to the
applicable Trust Agreement prior to the expiry of the 15-day notice period specified above, such Controlling Party may not direct the Subordination Agent or any Trustee to enter into any such restructuring
proposal with respect to any of the Aircraft unless and until such Certificateholder shall fail to purchase such Class of Certificates on the date that it is required to make such purchase. 

  
 23 

 SECTION 4.2. Remedies Cumulative. Each and every right, power and remedy given to the
Trustees, the Controlling Party or the Subordination Agent specifically or otherwise in this Agreement shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at law,
in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may, subject always to the terms and conditions hereof, be exercised from time to time and as often and in such order as may
be deemed expedient by any Trustee, the Controlling Party or the Subordination Agent, as appropriate, 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 any Trustee, the Controlling Party or the Subordination Agent in the exercise of any right, remedy or power or in the pursuit of any remedy shall impair any such right,
power or remedy or be construed to be a waiver of any default or to be an acquiescence therein. 
 SECTION 4.3. Discontinuance of
Proceedings. In case any party to this Agreement (including the Controlling Party in such capacity) shall have instituted any Proceeding to enforce any right, power or remedy under this Agreement by foreclosure, entry or otherwise, and such
Proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Person instituting such Proceeding, then and in every such case each such party shall, subject to any determination in such
Proceeding, be restored to its former position and rights hereunder, and all rights, remedies and powers of such party shall continue as if no such Proceeding had been instituted. 

SECTION 4.4. Right of Certificateholders to Receive Payments Not to Be Impaired. Anything in this Agreement to the contrary
notwithstanding but subject to each Trust Agreement, the right of any Certificateholder to receive payments hereunder (including without limitation pursuant to Section 3.2 hereof) when due, or to institute suit for the enforcement of any such
payment on or after the applicable Distribution Date, shall not be impaired or affected without the consent of such Certificateholder. 

SECTION 4.5. Undertaking for Costs. In any Proceeding for the enforcement of any right or remedy under this Agreement or in any
Proceeding against any Controlling Party or the Subordination Agent for any action taken or omitted by it as Controlling Party or Subordination Agent, as the case may be, a court in its discretion may require the filing by any party litigant in the
suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and
good faith of the claims or defenses made by the party litigant. The provisions of this Section do not apply to a suit instituted by the Subordination Agent or a Trustee or a suit by Certificateholders holding more than 10% of the original principal
amount of any Class of Certificates.

reports, notices, requests, demands, certificates, financial statements and other instruments furnished to the Subordination Agent as registered holder of the Equipment Notes or otherwise in its capacity as Subordination Agent to the extent the same

or expense (including counsel fees and expenses) which may be incurred in connection therewith. The Subordination Agent shall not be under any obligation to take any action under this Agreement and nothing contained in this Agreement shall require
the Subordination Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing
that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. The Subordination Agent shall not be required to take any action under Section 5.1 (other than the first sentence thereof) or
Article IV hereof, nor shall any other provision of this Agreement be deemed to impose a duty on the Subordination Agent to take any action, if the Subordination Agent shall have been advised by counsel that such action is contrary to the terms
hereof or is otherwise contrary to law.

activities hereunder or any other Operative Agreement. 
 SECTION 5.4. Notice from the Trustees. If any Trustee has notice of an
Indenture Default or a Triggering Event, such Person shall promptly give notice thereof to each other party hereto, provided, however, that no such Person shall have any liability hereunder as a result of its failure to deliver any
such notice.

supplement, amendment or modification shall not be effective without the additional written consent of Sun Country or (iii) if such supplement, amendment or modification would directly or
indirectly amend, modify or supersede, or otherwise conflict with, the last two sentences of Section 4.1(a)(i), then such supplement, amendment or modification shall not be effective without the unanimous consent of each Certificateholder.
Notwithstanding the foregoing, without the consent of each Certificateholder, no supplement, amendment or modification of this Agreement may (i) reduce the percentage of the interest in any Trust evidenced by the Certificates issued by such
Trust necessary to consent to modify or amend any provision of this Agreement or to waive compliance therewith or (ii) except as provided in this Section 9.1(a), Section 9.1(c) or Section 9.1(d), modify Section 2.4 or 3.2

related Participation Agreement or other related document, (i) if no Indenture Default shall have occurred and be continuing with respect to such Indenture, the Subordination Agent shall request directions with respect to each Series of such
Equipment Notes from the Trustee of the Trust which holds such Equipment Notes and shall vote or consent in accordance with the directions of such Trustee, and (ii) if any Indenture Default shall have occurred and be continuing with respect to

thereof) and, to the extent a Bankruptcy Event has occurred and is continuing, the Bankruptcy Code. 
 (c) If the Series B Equipment Notes
issued with respect to all of the Aircraft are repaid and re-issued in accordance with the terms of Section 4(a)(vi) of the Note Purchase Agreement, or any series of Additional Equipment Notes issued
pursuant to Section 9.1(d) are repaid and re-issued in accordance with Section 4(a)(vi) of the Note Purchase Agreement, such series of re-issued Equipment
Notes (the “Refinancing Equipment Notes”) shall be issued to a new pass through trust (a “Refinancing Trust”) that issues a class of pass through certificates (the “Refinancing Certificates”) to
certificateholders (the “Refinancing Certificateholders”) pursuant to a pass through trust agreement (a “Refinancing Trust Agreement”) with a trustee (a “Refinancing Trustee”). A Refinancing Trust,
a Refinancing Trustee and the Refinancing Certificates shall be subject to all of the provisions of this Agreement in the same manner as the Class B Trust or the applicable Additional Trust, the Class B Trustee or the applicable Additional
Trustee and the Class B Certificates or the applicable Additional Certificates, whichever 

  
 31 

 
corresponds to the series of the refinanced Equipment Notes, including the subordination of the Refinancing Certificates to the Administration Expenses, and the Class A Certificates and, if
applicable, the Class B Certificates and, if applicable, any previously issued class of Additional Certificates. Such issuance of Refinancing Equipment Notes and Refinancing Certificates and the amendment of this Agreement as provided below
shall require Ratings Confirmation (if any Class is then rated) and shall not materially adversely affect any of the Trustees. This Agreement shall be amended by written agreement of Sun Country and the Subordination Agent to give effect to the
issuance of any Refinancing Certificates subject to the following terms and conditions: 
 (i) the Refinancing Trustee shall
be added as a party to this Agreement; 
 (ii) the definitions of “Certificate”, “Class”,
“Class B Certificates” (if applicable), “Final Legal Distribution Date”, “Trust”, “Trust Agreement” and “Controlling Party” (and such other applicable definitions) shall be revised, as
appropriate, to reflect such issuance (and the subordination of the Refinancing Certificates and the Refinancing Equipment Notes); 

(iii) the Refinancing Certificates may be rated by one or more Rating Agencies, and may allow for payment in kind of interest
in a manner similar to the PIK Amounts; 
 (iv) the Refinancing Certificates cannot be issued to Sun Country but may be
issued to any of Sun Country’s Affiliates so long as such Affiliate shall have bankruptcy remote and special purpose provisions in its certificate of incorporation or other organizational documents and any subsequent transfer of the Refinancing
Certificates to any Affiliate of Sun Country shall be similarly restricted; and 
 (v) the scheduled payment dates on the
Refinancing Equipment Notes shall be on the Regular Distribution Dates. 
 The issuance of the Refinancing Certificates in compliance with
all of the foregoing terms of this Section 9.1(c) shall not require the consent of any of the Trustees or the holders of any Class of Certificates. 

(d) Pursuant to the terms of Section 2.02 of each Indenture and Section 4(a)(vi) of the Note Purchase Agreement, one or more
additional series of Equipment Notes (the “Additional Equipment Notes”), which shall be subordinated in right of payment to the Series A Equipment Notes and the Series B Equipment Notes under such Indenture, may be issued at any
time, and from time to time, on or after the final Closing Date. If any series of Additional Equipment Notes are issued under one or more of the Indentures, each such series of Additional Equipment Notes shall be issued to a new pass through trust
(an “Additional Trust”) that issues a class of pass through certificates (the “Additional Certificates”) to certificateholders (the “Additional Certificateholders”) pursuant to a pass through trust
agreement (an “Additional Trust Agreement”) with a trustee (an “Additional Trustee”). In such case, this Agreement shall be amended by written agreement of Sun Country and the Subordination Agent to provide for the
subordination of the Additional Certificates to the Administration Expenses, the Class A 

  
 32 

 
Certificates and the Class B Certificates, if applicable, any previously issued class of Additional Certificates (subject to clause (iii) below). Such issuance and the amendment of this
Agreement as provided below shall require Ratings Confirmation (if applicable) and shall not materially adversely affect any of the Trustees. This Agreement shall be amended by written agreement of Sun Country and the Subordination Agent to give
effect to the issuance of any Additional Certificates subject to the following terms and conditions: 
 (i) the Additional Trustee shall be
added as a party to this Agreement; 
 (ii) the definitions of “Certificate”, “Class”, “Equipment Notes”,
“Final Legal Distribution Date”, “Trust”, “Trust Agreement” and “Controlling Party” (and such other applicable definitions) shall be revised, as appropriate, to reflect the issuance of the Additional
Certificates (and the subordination thereof); 
 (iii) Section 3.2 may be revised to provide for the distribution of “PIK
Amounts” (calculated in a manner similar to the calculation of PIK Amounts for the Class B Certificates) and “Adjusted Interest” (calculated in a manner substantially similar to the calculation of Class B Adjusted Interest)
for such class of Additional Certificates after the Class B Adjusted Interest (and, if applicable, after any “Adjusted Interest” for any previously issued class of Additional Certificates) but before Expected Distributions on the
Class A Certificates; 
 (iv) the Additional Certificates may be rated by one or more Rating Agencies; 

(v) the Additional Certificates may allow for payment in kind of interest as “PIK Amounts” in a manner similar to the PIK Amounts in
respect of the Class B Certificates; 
 (vi) the Additional Certificates cannot be issued to Sun Country but may be issued to any of
Sun Country’s Affiliates so long as such Affiliate shall have bankruptcy remote and special purpose provisions in its certificate of incorporation or other organizational documents and any subsequent transfer of the Additional Certificates to
any Affiliate of Sun Country shall be similarly restricted; 
 (vii) the provisions of this Agreement governing payments with respect to
Certificates and related notices, including Sections 2.4, 3.1 and 3.2, shall be revised to provide for distributions on such class of the Additional Certificates after payment of Administration Expenses, the Class A Certificates and the
Class B Certificates (and, if applicable, any previously issued class of Additional Certificates), subject to clause (iii) above; and 

(viii) the scheduled payment dates on such series of Additional Equipment Notes shall be on the Regular Distribution Dates. 

The issuance of the Additional Certificates in compliance with all of the foregoing terms of this Section 9.1(d) shall not require the
consent of any of the Trustees or the holders of any Class of Certificates. 
 SECTION 9.2. Subordination Agent Protected. If,
in the reasonable opinion of the institution acting as the Subordination Agent hereunder, any document required to be executed pursuant to the terms of Section 9.1 affects any right, duty, immunity or indemnity with respect to it under this
Agreement, the Subordination Agent may in its discretion decline to execute such document. 

  
 33 

 SECTION 9.3. Effect of Supplemental Agreements. Upon the execution of any amendment,
consent or supplement hereto pursuant to the provisions hereof, this Agreement shall be and be deemed to be and shall be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and
immunities under this Agreement of the parties hereto and beneficiaries hereof shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any
such amendment, consent or supplement shall be and be deemed to be and shall be part of the terms and conditions of this Agreement for any and all purposes. In executing or accepting any amendment, consent or supplement permitted by this Article IX,
the Subordination Agent shall be entitled to receive, and shall be fully protected in relying upon, an opinion of counsel stating that the execution of such amendment, consent or supplement is authorized or permitted by this Agreement. 

SECTION 9.4. Notice to Rating Agency. Promptly upon receipt of any amendment, consent, modification, supplement or
waiver contemplated by this Article IX and prior to taking any action required to be taken thereunder, the Subordination Agent shall send a copy thereof to each Rating Agency.

 NOTE PURCHASE AGREEMENT 

This NOTE PURCHASE AGREEMENT, dated as of March 28, 2022 (this “Agreement”), is among (i) SUN COUNTRY, INC., a
Minnesota corporation (the “Company”), (ii) WILMINGTON TRUST, NATIONAL ASSOCIATION, a national banking association (“WTNA”), not in its individual capacity except as otherwise expressly provided herein, but solely as
trustee (in such capacity together with its successors in such capacity, the “Pass Through Trustee”) under each of the two separate Pass Through Trust Agreements (as defined below) and (iii) WTNA, as subordination agent and
trustee (in such capacity together with its successors in such capacity, the “Subordination Agent”) under the Intercreditor Agreement (as defined below). 

W I T N E S S E T H: 
 WHEREAS,
capitalized terms used but not defined herein shall have the meanings ascribed to such terms in Annex A hereto; 
 WHEREAS, the Company
owns, or has agreed to acquire, the thirteen Boeing 737-800 aircraft listed in Schedule I hereto (the “Aircraft”); 

WHEREAS, pursuant to this Agreement the Company wishes to finance each of the Aircraft hereunder; 

WHEREAS, pursuant to the Basic Pass Through Trust Agreement and each of the Trust Supplements set forth in Schedule II hereto, and
concurrently with the execution and delivery of this Agreement, separate grantor trusts (the “Class A Pass Through Trust” and the “Class B Pass Through Trust”, collectively, the
“Pass Through Trusts” and, individually, a “Pass Through Trust”) have been created to facilitate certain of the transactions contemplated hereby, including, without limitation, the issuance and sale of pass through
certificates pursuant thereto (collectively, the “Certificates”) to provide for a portion of the financing of the Aircraft contemplated hereby; 

WHEREAS, the Company has entered into the Certificate Purchase Agreement, dated as of the date hereof (as amended, supplemented or otherwise
modified from time to time in accordance with its terms, the “Purchase Agreement”) with the investors named therein (each an “Investor” and collectively, the “Investors”), pursuant to which the
Company will cause the Pass Through Trustee under the Class A Pass Through Trust (the “Class A Pass Through Trustee”) and the Pass Through Trustee under the Class B Pass Through Trust (the
“Class B Pass Through Trustee) to issue and sell the Class A Certificates and the Class B Certificates, respectively, to the Investors on and subject to the terms set out in the Purchase Agreement; 

WHEREAS, upon receipt of a Closing Notice with respect to an Aircraft, subject to the terms and conditions of this Agreement, the applicable
Pass Through Trustees will enter into the applicable Financing Agreements relating to such Aircraft; and 
 WHEREAS, in order to effect the
financing of each Aircraft, the Class A Pass Through Trustee and the Class B Pass Through Trustee, each will fund its purchase of Equipment Notes with the proceeds of the sale of the Certificates by the related Pass Through Trust pursuant
to the Purchase Agreement. 
  

 NOW, THEREFORE, in consideration of the foregoing premises and the mutual agreements herein
contained and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

SECTION 1. Financing of Aircraft. (a) The Company confirms that it currently owns, or has agreed to acquire, the Aircraft. The
Company agrees to finance the Aircraft in the manner provided herein, all on and subject to the terms and conditions hereof and of the relevant Financing Agreements. 

(b) In furtherance of the foregoing, the Company agrees to give the parties hereto and each of the Rating Agencies not less than one Business
Day’s prior notice substantially in the form of Exhibit A hereto (a “Closing Notice”) of the date on which the Company expects to finance an Aircraft hereunder, which shall be the Scheduled Closing Date for such Aircraft
(and the Company shall endeavor to finance each Aircraft on its Scheduled Delivery Date, provided the Company may, concurrently with the delivery of any Closing Notice, deliver a notice of postponement in accordance with Section 1(e)) or a
Business Day thereafter and before the Cut-off Date for such Aircraft, which notice shall: 
 (i)
specify the expected Closing Date of such Aircraft; 
 (ii) instruct each Pass Through Trustee being requested to purchase Equipment Notes
pursuant to such Closing Notice (the “Applicable Pass Through Trustees”) to enter into the Participation Agreement included in the Financing Agreements with respect to such Aircraft in such form and at such a time on or before the
expected Closing Date specified in such Closing Notice and to perform its obligations thereunder; 
 (iii) [Reserved]; and 

(iv) specify the aggregate principal amount of each series of Equipment Notes, if any, to be issued, and purchased by the Applicable Pass
Through Trustees, in connection with the financing of such Aircraft scheduled on such expected Closing Date (which shall in all respects comply with the Required Terms). 

Notwithstanding the foregoing, in the case of any Aircraft to be financed hereunder on the Initial Closing Date, the Closing Notice therefor may be delivered
to the parties hereto on the Initial Closing Date. 
 (c) Upon receipt of a Closing Notice, the Applicable Pass Through Trustees shall, and
shall cause the Subordination Agent to, enter into and perform their respective obligations under each Participation Agreement specified in such Closing Notice, provided that such Participation Agreement and the Indenture to be entered into
pursuant to such Participation Agreement shall be in the forms thereof annexed hereto in all material respects and, if modified in any material respect, as to which Rating Agency Confirmation shall have been obtained from each Rating Agency by the
Company (to be delivered by the Company to the Applicable Pass Through Trustees on or before the Closing Date on which such Participation Agreement is to be 

  
 2 

 
entered into, it being understood that if a Rating Agency Confirmation shall have been received with respect to any Financing Agreements and such Financing Agreements are utilized for subsequent
Aircraft without material modifications, no additional Rating Agency Confirmation shall be required); provided, however, that the relevant Financing Agreements as executed and delivered shall not vary the Required Terms.
Notwithstanding the foregoing, an Indenture may be modified to the extent required for the issuance of Equipment Notes pursuant to Section 4(a)(vi) of this Agreement, subject to the terms of such Section and Section 9.1(c) or 9.1(d) of the
Intercreditor Agreement, whichever may be applicable. The Company shall pay the reasonable costs and expenses of the Rating Agencies in connection with obtaining any such Rating Agency Confirmation. With respect to each Aircraft, the Company shall
cause WTNA (or such other person that meets the eligibility requirements to act as loan trustee under the Indenture) to execute as Loan Trustee the Financing Agreements relating to such Aircraft to which such Loan Trustee is intended to be a party,
and shall concurrently therewith execute such Financing Agreements to which the Company is intended to be a party and perform its respective obligations thereunder. Upon the request of any Rating Agency, the Company shall deliver or cause to be
delivered to such Rating Agency a true and complete copy of each Financing Agreement relating to the financing of each Aircraft together with a true and complete set of the closing documentation (including legal opinions) delivered to the related
Loan Trustee, Subordination Agent and Pass Through Trustee under the related Participation Agreement. 
 (d) The Company agrees that all
Equipment Notes issued pursuant to any Indenture shall initially be registered in the name of the Subordination Agent on behalf of the Applicable Pass Through Trustees (or, in the case of any Additional Series Equipment Notes, on behalf of the
Additional Series Pass Through Trustee with respect to the corresponding Additional Series Pass Through Certificates). 
 (e) If after giving
any Closing Notice, the financing of any Aircraft referred to therein (the “Delayed Aircraft”) in the manner contemplated hereby shall not be consummated for any reason the Company shall give the parties hereto prompt notice
thereof. Concurrently with the giving of such notice of postponement or subsequently, the Company shall give the parties hereto a substitute Closing Notice specifying the date to which the financing of such Delayed Aircraft shall have been re-scheduled, which shall be a Business Day before the Cut-off Date for such Aircraft. Following the giving of such notice of postponement, the unapplied funds advanced by the
Class A Certificateholders and the Class B Certificateholders under the Purchase Agreement intended to fund the purchase of the Equipment Notes relating to such Delayed Aircraft, shall, pursuant to Section 2.1(d) of the Purchase
Agreement, be held in a separate account with WTNA for the benefit of such Certificateholders with respect to such Equipment Notes until the earlier of (x) the application of such funds to purchase the relevant Equipment Notes with respect to
such Delayed Aircraft and (y) the date that is 30 days after the Scheduled Closing Date with respect to such Delayed Aircraft or, in the case of any Extension Aircraft, such later day prior to the 60th day after such Scheduled Closing Date to
which such 30th day has most recently been postponed by written notice from the Company to the Pass Through Trustees given prior to expiration of the deadline in effect under this clause (y) when such notice is given (such 30th day or, if
applicable, later day, the “Prefunding Expiry Date”); provided that if the Equipment Notes relating to such Delayed Aircraft have not been purchased prior to the applicable Prefunding Expiry Date (which, for the avoidance of doubt,
may be the Cut-off Date), such unapplied funds shall be paid as provided in the Purchase Agreement. If a 

  
 3 

 
notice of postponement has been given with respect to an Aircraft, the financing of such Aircraft, as specified in a substitute Closing Notice, shall take place on the re-scheduled Closing Date therefor (all on and subject to the terms and conditions of the relevant Financing Agreements) unless further postponed as provided herein. 

(f) The Company shall have no liability for the failure of the Pass Through Trustees to purchase Equipment Notes with respect to any Aircraft.

 SECTION 2. Conditions Precedent. The obligation of the Applicable Pass Through Trustees to enter into, and to cause the
Subordination Agent to enter into, any Participation Agreement as directed pursuant to a Closing Notice and to perform its obligations thereunder is subject to satisfaction of the following conditions: 

(a) no Triggering Event shall have occurred; and 

(b) the Company shall have delivered a certificate to each such Pass Through Trustee stating (i) that such Participation Agreement and the
other Financing Agreements to be entered into pursuant to such Participation Agreement do not vary the Required Terms and (ii) that any substantive modification of such Financing Agreements from the forms of Financing Agreements attached to
this Agreement do not materially and adversely affect the Certificateholders, and such certification shall be true and correct. 
 Anything
herein to the contrary notwithstanding, the obligation of each Pass Through Trustee to purchase Equipment Notes with respect to an Aircraft shall terminate on the Cut-off Date with respect to such Aircraft.

 SECTION 3. Representations and Warranties. (a) The Company represents and warrants that: 

(i) the Company is duly incorporated, validly existing and in good standing under the laws of the State of Minnesota and is a
“citizen of the United States” as defined in Section 40102(a)(15) of the Act, and has the full corporate power, authority and legal right under the laws of the State of Minnesota to execute and deliver this Agreement and each
Financing Agreement to which it will be a party and to carry out the obligations of the Company under this Agreement and each Financing Agreement to which it will be a party; 

(ii) the execution and delivery by the Company of this Agreement and the performance by the Company of its obligations under
this Agreement have been duly authorized by the Company and will not violate its Certificate of Incorporation or by-laws or the provisions of any indenture, mortgage, contract or other agreement to which it is
a party or by which it is bound; and 
 (iii) this Agreement constitutes the legal, valid and binding obligation of the
Company, enforceable against it in accordance with its terms, except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors generally and by general principles of
equity, whether considered in a proceeding at law or in equity.

United States and is a “citizen of the United States” as defined in Section 40102(a)(15) of the Act, and has the full corporate power, authority and legal right under the laws of the United States and of the state of the United States
in which it is located pertaining to its banking, trust and fiduciary powers to execute and deliver this Agreement and each Financing Agreement to which it will be a party and to carry out the obligations of WTNA, in its capacity as Subordination
Agent or Pass Through Trustee, as the case may be, under this Agreement and each Financing Agreement to which it will be a party; 

(ii) the execution and delivery by WTNA, in its capacity as Subordination Agent or Pass Through Trustee, as the case may be, of
this Agreement and the performance by WTNA, in its capacity as Subordination Agent or Pass Through Trustee, as the case may be, of its obligations under this Agreement have been duly authorized by WTNA, in its capacity as Subordination Agent or Pass
Through Trustee, as the case may be, and will not violate its articles of association or by-laws or the provisions of any indenture, mortgage, contract or other agreement to which it is a party or by which it
is bound; and 
 (iii) this Agreement constitutes the legal, valid and binding obligations of WTNA, in its capacity as
Subordination Agent or Pass Through Trustee, as the case may be, enforceable against it in accordance with its terms, except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
rights of creditors generally and by general principles of equity, whether considered in a proceeding at law or in equity.

Through Trustee hereby confirms to each of the other parties hereto that its representations and warranties set forth in Section 7.15 of the Basic Pass Through Trust Agreement and Section 6.03 of each Trust Supplement are true and correct
as of the date hereof.

then subject to the lien of an Indenture: (A) whether the Aircraft are currently in service or parked in storage, (B) the maintenance status of the Aircraft and (C) the location of the Engines (as defined in the respective Indentures
to which such Aircraft are subject). As used in the preceding sentence, the terms “Triggering Event”, “Indenture Default”, and “Regular Distribution Date” shall have the respective meanings set forth in the
Intercreditor Agreement as originally executed. 
 (b) WTNA, in its individual capacity, covenants with each of the other parties to this
Agreement that it will, immediately upon obtaining knowledge of any facts that would cast doubt upon its continuing status as a “citizen of the United States” as defined in Section 40102(a)(15) of the Act and promptly upon public
disclosure of negotiations in respect of any transaction which would or might adversely affect such status, notify in writing all parties hereto of all relevant matters in connection therewith. Upon WTNA giving any such notice, WTNA shall, subject
to Section 9.01 of any Indenture then entered into, resign as Loan Trustee in respect of such Indenture.

 SECTION 6. Expenses. So long as no Equipment Notes have been issued in respect of any Aircraft, the Company
agrees to pay, (i) all compensation and reimbursement of expenses, disbursements and advances payable by the Company under the Pass Through Trust Agreements and (ii) all compensation and reimbursement of expenses and disbursements payable
to the Subordination Agent under the Intercreditor Agreement except with respect to any income or franchise taxes incurred by the Subordination Agent in connection with the transactions contemplated by the Intercreditor Agreement.

Owner’s right, title and interest in and to the Aircraft shall continue as a valid and duly perfected first priority security interest and International Interest and all filing, recording or other action necessary to protect the same shall have
been accomplished (or, if such opinion cannot be given at the 

  

			
	PARTICIPATION AGREEMENT 22-1 (A and B)	  	PAGE 17

 
time of such proposed change in registration because such change in registration is not yet effective, (1) the opinion shall detail what filing, recording or other action is necessary and
(2) the Mortgagee shall have received a certificate from Owner that all possible preparations to accomplish such filing, recording and other action shall have been done, and such filing, recording and other action shall be accomplished and a

(C) unless Owner or the Permitted Air Carrier shall have agreed to provide insurance covering the risk of requisition of use of

Dollars and freely removable from such country (without license or permit, unless Owner prior to such proposed reregistration has obtained such license or permit) for the taking or requisition by such government of such use; and 

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

to Mortgagee: 
  

	 	(i)	 to the effect that the provisions of Section 4.06 of the Trust Indenture have been complied with after
giving effect to such change of registration;

of Mortgagee for the benefit of Note Holders, and (3) all costs and expenses incurred in connection with any filings necessary to continue in the United States the perfection of the security interest in the Aircraft in favor of Mortgagee for
the benefit of Note Holders; and 

 (iii) to the effect that the tax and other indemnities in favor of each person named

indemnities, in the reasonable judgment of Mortgagee, afford such protection).

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

such Indemnitee to agree in writing to the terms of this Section 8 and Section 12.8 prior to making any payment to such Indemnitee under this Section 8.

for or control of any judicial proceeding with respect thereto. 
 8.1.6 Information 

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

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

Mortgagee to hold as security for Owner’s obligations under the Operative Agreements or, if requested by Owner, applied to satisfy such obligations. 

8.2 Expenses 
 8.2.1

day after the Closing Date). If so submitted and approved, the Owner agrees promptly, but in any event no later than the 105th day after the Closing Date, to pay Transaction Expenses.

 Except as
provided in Section 8.3.2, Owner agrees that each payment paid by Owner under the Equipment Notes, and any other payment or indemnity paid by Owner to a Tax Indemnitee under any Operative Agreement, shall be free of all withholdings or
deductions with respect to Taxes of any nature (other than U.S. federal, state or local withholding taxes on, based on or measured by gross or net income, including, without limitation, any such taxes imposed under FATCA), and in the event that
Owner shall be required by applicable law to make any such withholding or deduction for any such payment (x) Owner shall make all such withholdings or deductions, (y) the amount payable by Owner shall be increased so that after making all

Authority in accordance with applicable law. Except as provided in Section 8.3.2 and whether or not any of the transactions contemplated hereby are consummated, Owner shall pay, indemnify, protect, defend and hold each Tax Indemnitee harmless
from all Taxes imposed by any Taxing Authority that may from

time to time be imposed on or asserted against any Tax Indemnitee or the Aircraft, the Airframe, any Engine or any Part or any interest in any of the foregoing (whether or not indemnified against

 8.3.3 Payment 

(a) Owner’s indemnity obligation to a Tax Indemnitee under this Section 8.3 shall equal the amount which, after taking into account
any Tax imposed upon the receipt or accrual of the amounts payable under this Section 8.3 and any tax benefits actually recognized by such Tax Indemnitee as a result of the indemnifiable Tax (including, without limitation, any benefits
recognized as a result of an indemnifiable Tax being utilized by such Tax Indemnitee as a credit against Taxes not indemnifiable under this Section 8.3), shall equal the amount of the Tax indemnifiable under this Section 8.3. 

(b) At Owner’s request, the computation of the amount of any indemnity payment owed by Owner or any amount owed by a Tax Indemnitee to
Owner pursuant to this Section 8.3 shall be verified and certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably satisfactory to Owner. Such verification shall be binding. The costs of such verification
(including the fee of such public accounting firm) shall be borne by Owner unless such verification shall result in an adjustment in Owner’s favor of 5% or more of the net present value of the payment as computed by such Tax Indemnitee, in
which case the costs shall be paid by such Tax Indemnitee. 
 (c) Each Tax Indemnitee shall provide Owner with such certifications,
information and documentation as shall be in such Tax Indemnitee’s possession and as shall be reasonably requested by Owner to minimize any indemnity payment pursuant to this Section 8.3; provided, that notwithstanding anything to the
contrary contained herein, no Tax Indemnitee shall be required to provide Owner with any Tax returns. 
 (d) Each Tax Indemnitee shall
promptly forward to Owner any written notice, bill or advice received by it from any Taxing Authority concerning any Tax for which it seeks indemnification under this Section 8.3. Owner shall pay any amount for which it is liable pursuant to
this Section 8.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if 

  

			
	PARTICIPATION AGREEMENT 22-1 (A and B)	  	PAGE 27

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

(e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or indemnified by Owner pursuant to this
Section 8.3 (whether such tax savings shall be by means of a foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not otherwise taken into account in computing such payment or indemnity such Tax
Indemnitee shall pay to Owner an amount equal to the lesser of (i) the amount of such tax savings, plus any additional tax savings recognized as the result of any payment made pursuant to this sentence, when, as, if, and to the extent, realized
or (ii) the amount of all payments pursuant to this Section 8.3 by Owner to such Tax Indemnitee (less any payments previously made by such Tax Indemnitee to Owner pursuant to this Section 8.3.3 (e)) (and the excess, if any, of the
amount described in clause (i) over the amount described in clause (ii) shall be carried forward and applied to reduce pro tanto any subsequent obligations of Owner to make payments to such Tax Indemnitee pursuant to this
Section 8.3); provided, that such Tax Indemnitee shall not be required to make any payment pursuant to this sentence so long as a Lease Event of Default of a monetary nature has occurred and is continuing. If a tax benefit is later disallowed
or denied, the disallowance or denial shall be treated as a Tax indemnifiable under Section 8.3.1 without regard to the provisions of Section 8.3.2 (other than Section 8.3.2 (f)). Each such Tax Indemnitee shall in good faith use
reasonable efforts in filing its tax returns and in dealing with Taxing Authorities to seek and claim any such tax benefit. 
 8.3.4
Contest 
 (a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Owner could be liable for payment or
indemnity hereunder, or if a Tax Indemnitee makes a determination that a Tax is due for which Owner could have an indemnity obligation hereunder, such Tax Indemnitee shall promptly give Owner notice in writing of such claim (provided, that failure
to so notify Owner shall not relieve Owner of its indemnity obligations hereunder unless such failure to notify effectively forecloses Owner’s rights to require a contest of such claim) and shall take no action with respect to such claim
without the prior written consent of Owner for 30 days following the receipt of such notice by Owner; provided, that, in 

  

			
	PARTICIPATION AGREEMENT 22-1 (A and B)	  	PAGE 28

 
the case of a claim made against a Tax Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such 30-day period,
such Tax Indemnitee shall, in such notice to Owner, so inform Owner, and such Tax Indemnitee shall take no action for as long as it is legally able to do so (it being understood that a Tax Indemnitee shall be entitled to pay the Tax claimed and sue
for a refund prior to the end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial penalties (unless immediately reimbursed by Owner) and the act of paying the Tax
would not materially prejudice the right to contest or (B) the failure to so pay would result in criminal penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so paying the Tax in a manner that is the
least prejudicial to the pursuit of the contest). In addition, such Tax Indemnitee shall (provided, that Owner shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim) furnish Owner
with copies of any requests for information from any Taxing Authority relating to such Taxes with respect to which Owner may be required to indemnify hereunder. If requested by Owner in writing within 30 days after its receipt of such notice, such
Tax Indemnitee shall, at the expense of Owner (including, without limitation, all reasonable costs, expenses and reasonable attorneys’ and accountants’ fees and disbursements), in good faith contest (or, if permitted by applicable law,
allow Owner to contest) through appropriate administrative and judicial proceedings the validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying the same except under protest if protest is necessary
and proper or (III) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or judicial proceeding. If requested to do so by Owner, the Tax Indemnitee shall appeal any adverse
administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue any appeals to the United States Supreme Court. If and to the extent the Tax Indemnitee is able to separate the contested issue or issues from other
issues arising in the same administrative or judicial proceeding that are unrelated to the transactions contemplated by the Operative Agreements without, in the good faith judgment of such Tax Indemnitee, adversely affecting such Tax Indemnitee,
such Tax Indemnitee shall permit Owner to control the conduct of any such proceeding and shall provide to Owner (at Owner’s cost and expense) with such information or data that is in such Tax Indemnitee’s control or possession that is
reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Owner in good faith regarding the manner of contesting such claim and shall keep Owner reasonably informed
regarding the progress of such contest. A Tax Indemnitee shall not fail to take any action 
 expressly required by this Section 8.3.4 (including,
without limitation, any action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without the prior written consent of the Owner (except as contemplated by Section 8.3.4(b) or (c)).

 (b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Owner to pursue any
contest) unless (i) Owner shall have agreed to pay such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in connection with contesting such Taxes, including, without limitation, all reasonable out of
pocket costs and expenses and reasonable attorneys’ and accountants’ fees and disbursements, (ii) if such contest shall involve the payment of the claim, Owner shall advance the amount thereof (to the extent indemnified hereunder)
plus interest, penalties and additions to tax with respect thereto that are required to be paid prior to the commencement of such contest on an interest-free after-Tax basis to such Tax Indemnitee (and such
Tax Indemnitee shall 

  

			
	PARTICIPATION AGREEMENT 22-1 (A and B)	  	PAGE 29

 
promptly pay to the Owner any net realized tax benefits resulting from such advance including any tax benefits resulting from making such payment), (iii) such Tax Indemnitee shall have reasonably
determined that the action to be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless Owner shall have made provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory
to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to notify Owner in writing promptly after it becomes aware of any such risk), (iv) no Lease Event of Default shall have occurred and be continuing unless Owner has provided security
for its obligations hereunder by advancing to such Tax Indemnitee before proceeding or continuing with such contest, the amount of the Tax being contested, plus any interest and penalties and an amount estimated in good faith by such Tax Indemnitee
for expenses, and (v) prior to commencing any judicial action controlled by Owner, Owner shall have acknowledged its liability for such claim hereunder, provided that Owner shall not be bound by its acknowledgment if the Final Determination
articulates conclusions of law and fact that demonstrate that Owner has no liability for the contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release, waive, compromise or settle any claim which may be
indemnifiable by Owner pursuant to this Section 8.3 without the written permission of Owner, Owner’s obligation to indemnify such Tax Indemnitee with respect to such claim (and all directly related claims and claims based on the outcome of
such claim) shall terminate, subject to Section 8.3.4(c), and subject to Section 8.3.4(c), such Tax Indemnitee shall repay to Owner any amount previously paid or advanced to such Tax Indemnitee with respect to such claim, plus interest at
the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax. 
 (c) Notwithstanding anything
contained in this Section 8.3, a Tax Indemnitee will not be required to contest the imposition of any Tax and shall be permitted to settle or compromise any claim without Owner’s consent if such Tax Indemnitee (i) shall waive its
right to indemnity under this Section 8.3 with respect to such Tax (and any directly related claim and any claim the outcome of which is determined based upon the outcome of such claim), (ii) shall pay to Owner any amount previously paid or
advanced by Owner pursuant to this Section 8.3 with respect to such Tax, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax, and (iii) shall agree to discuss with
Owner the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax. 
 8.3.5 Refund 

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

 8.3.6 Tax Filing 

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

8.3.7 Forms 
 Each Tax
Indemnitee agrees to furnish from time to time to Owner or Mortgagee or to such other person as Owner or Mortgagee may designate, at Owner’s or Mortgagee’s request, such duly executed and properly completed forms as may be necessary or
appropriate in order to claim any reduction of or exemption from any withholding or other Tax imposed by any Taxing Authority, if (x) such reduction or exemption is available to such Tax Indemnitee and (y) Owner has provided such Tax
Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee. 
 8.3.8 Non-Parties 
 If a Tax Indemnitee is not a party to this Agreement, Owner may require the Tax
Indemnitee to agree in writing, in a form reasonably acceptable to Owner, to the terms of this Section 8.3 and Section 12.8 prior to making any payment to such Tax Indemnitee under this Section 8.3. 

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

  

			
	PARTICIPATION AGREEMENT 22-1 (A and B)	  	PAGE 31

 8.4 Payments 

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

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

The obligations of Owner in respect of all indemnities, obligations, adjustments and payments in Section 8.1 or 8.3 are expressly made for
the benefit of, and shall be enforceable by, the Indemnitee or Tax Indemnitee entitled thereto, notwithstanding any provision of the Trust Indenture. 

SECTION 9. ASSIGNMENT OR TRANSFER OF INTEREST 

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

 9.2 Effect of Transfer 

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

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

SECTION 11. CHANGE OF CITIZENSHIP 

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

relevant matters in connection therewith. 
 11.2 Mortgagee 

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

distinction or priority of any one Equipment Note over any other, or any Related Equipment Note over any other, by reason of priority of time of issue, sale, negotiation, date of maturity thereof or otherwise for any reason whatsoever, and for the
uses and purposes and in all cases and as to all property specified in clauses (1) through (5) inclusive above, subject to the terms and provisions set forth in this Trust Indenture. 

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

consideration and coupled with an interest and with full power of substitution, and with full power (in the name of the Owner or otherwise) to ask for, require, demand, receive, compound and give acquittance for any and all monies and claims for

 SECTION 2.02. Issuance and Terms of Equipment Notes 

The Equipment Notes (other than the Additional Series Equipment Notes) shall be dated the Closing Date, shall be issued in three separate
series consisting of Series A and Series B and in the maturities and principal amounts and shall bear interest as specified in Schedule I hereto. On the Closing Date, each Series specified in Schedule I shall be issued to the Subordination Agent on
behalf of the Applicable Pass Through Trustee under the Applicable Pass Through Trust Agreement. In addition to the foregoing, Owner shall have the option to issue one or more separate series of Additional Series Equipment Notes at any time and
from time to time at or after the final “Closing Date” (as defined in the Note Purchase Agreement), subject to the terms of Section 4(a)(vi) of the Note Purchase Agreement and Section 9.1(d) of the Intercreditor Agreement. If
more than one series of Additional Series Equipment Notes are so issued, each such series shall have a different designation such as, for example, “Series C” and “Series D”, shall be dated the date of original issuance thereof
and shall have such maturities, principal amounts and interest rates as specified in an amendment to this Trust Indenture. The Equipment Notes shall be issued in registered form only. The Equipment Notes shall be issued in denominations of $1,000
and integral multiples thereof, except that one Equipment Note of each Series may be in an amount that is not an integral multiple of $1,000. Without limitation of the foregoing, new Series B Equipment Notes may be issued pursuant to the provisions
of Section 4(a)(vi) of the Note Purchase Agreement and Section 9.1(c) of the Intercreditor Agreement. 
 Each Equipment Note shall
bear interest at the applicable Debt Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on the unpaid Original Amount thereof from time to time outstanding. Accrued interest
shall be payable in arrears on [_______], 20[__]6, and on each [March 15 and September 15]7 thereafter until maturity. The Original Amount of
each Equipment Note shall be payable on the dates and in the installments equal to the corresponding percentage of the Original Amount as set forth in Schedule I hereto for the applicable Series (as amended, in the case of any Additional Series, at
the time of original issuance of such Additional Series) which shall be attached as Schedule I to such Equipment Notes. Notwithstanding the foregoing, the final payment made under each Equipment Note shall be in an amount sufficient to discharge in
full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, such Equipment Note. Each Equipment Note shall bear interest, payable on demand, at the Payment Due Rate (calculated on the basis of a year of
360 days comprised of twelve 30-day months) on any part of the Original Amount, Make-Whole Amount, if any, and, to the extent permitted by applicable Law, interest and any other amounts payable thereunder not
paid when due for any period during which the same shall be overdue, in each case for the period the same is overdue. Amounts under any Equipment Note shall be overdue if not paid when due (whether at stated maturity, by acceleration or otherwise).
Notwithstanding anything to the contrary contained herein, if any date on which a payment 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 and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment during such extension.

	TRUST INDENTURE 22-1 (A and B)	  	11

 The Owner agrees to pay to the Mortgagee for distribution in accordance with
Section 3.04 hereof: (a) Owner’s pro rata share of all compensation and reimbursement of expenses, disbursements and advances payable by Owner under the Pass Through Trust Agreements and (b) Owner’s pro rata share of all
compensation and reimbursement of expenses and disbursements payable to the Subordination Agent under the Intercreditor Agreement except with respect to any income or franchise taxes incurred by the Subordination Agent in connection with the
transactions contemplated by the Intercreditor Agreement. As used herein, “Owner’s pro rata share” means as of any time a fraction, the numerator of which is the principal balance then outstanding of Equipment Notes and the
denominator of which is the aggregate principal balance then outstanding of all “Equipment Notes” (as each such term is defined in each of the Operative Indentures). 

The Equipment Notes shall be executed on behalf of the Owner by one of its authorized officers. Equipment Notes bearing the signatures of
individuals who were at any time the proper officers of the Owner shall bind the Owner, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes or did not
hold such offices at the respective dates of such Equipment Notes. The Owner may from time to time execute and deliver Equipment Notes with respect to the Aircraft to the Mortgagee for authentication upon original issue and such Equipment Notes
shall thereupon be authenticated and delivered by the Mortgagee upon the written request of the Owner signed by an authorized officer of the Owner. No Equipment Note shall be secured by or entitled to any benefit under this Trust Indenture or be
valid or obligatory for any purposes, unless there appears on such Equipment Note a certificate of authentication in the form provided for herein executed by the Mortgagee by the manual signature of one of its authorized officers and such
certificate upon any Equipment Notes be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder. 

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

SECTION 2.03. [Intentionally Omitted] 

SECTION 2.04. Method of Payment 

(a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due under each Equipment Note or hereunder will be
payable in Dollars by wire transfer of immediately available funds not later than 12:30 PM, New York time, on the due date of payment to the Mortgagee at the Corporate Trust Office for distribution among the Note Holders in the manner provided
herein, and payment of such amount by the Owner to the 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	12

 
Mortgagee shall be deemed to satisfy the Owner’s obligation to make such payment. The Owner shall not have any responsibility for the distribution of such payment to any Note Holder.
Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the Mortgagee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any Note Holder (with a copy to the Owner), all amounts paid by
the Owner hereunder and under such holder’s Equipment Note or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant to Article III of this Trust Indenture) by transferring, or causing to be
transferred, by wire transfer of immediately available funds in Dollars, prior to 2:00 p.m., New York City time, on the due date of payment, to an account maintained by such holder with a bank located in the continental United States the amount to
be distributed to such holder, for credit to the account of such holder maintained at such bank. If the Mortgagee shall fail to make any such payment as provided in the immediately foregoing sentence after its receipt of funds at the place and prior
to the time specified above, the Mortgagee, in its individual capacity and not as trustee, agrees to compensate such holders for loss of use of funds at Debt Rate until such payment is made and the Mortgagee shall be entitled to any interest earned
on such funds until such payment is made. Any payment made hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall
be surrendered to the Mortgagee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Mortgagee shall not be required to make, or cause to be made, wire transfers as aforesaid
prior to the first Business Day on which it is practicable for the Mortgagee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 PM, New York time, at the place of
payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner and the Mortgagee shall deem and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner
and holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and none of the Owner or the Mortgagee shall be affected by any notice to the contrary. So
long as any signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to the account of such Note Holder specified in Schedule 1 thereto and otherwise in the manner provided in or
pursuant to the Participation Agreement unless it shall have specified some other account or manner of payment by notice to the Mortgagee consistent with this Section 2.04. 

(b) The Mortgagee, as agent for the Owner, shall exclude and withhold at the appropriate rate from each payment of Original Amount of,
interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes,
including, without limitation, any such withholding taxes imposed under FATCA applicable thereto as required by Law. The Mortgagee agrees to act as such withholding agent and, in connection therewith, whenever any present or future United States
taxes or similar charges are required to be withheld with respect to any amounts payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of
the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner) appropriate
receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time. 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	13

 If a Note Holder which is a Non-U.S. Person has
furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8BEN or
W-8BEN-E (or such successor form or forms as may be required by the United States Treasury Department) during the calendar year in which the payment hereunder or under
the Equipment Note(s) held by such holder is made (but prior to the making of such payment), or in either of the two preceding calendar years, and has not notified the Mortgagee of the withdrawal or inaccuracy of such form prior to the date of such
payment (and the Mortgagee has no reason to believe that any information set forth in such form is inaccurate), the Mortgagee shall withhold only the amount, if any, required by Law (after taking into account any applicable exemptions properly
claimed by the Note Holder) to be withheld from payments hereunder or under the Equipment Notes held by such holder in respect of United States federal income tax, including any amounts required to be withheld under FATCA. If a Note Holder
(x) which is a Non-U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8ECI in
duplicate (or such successor certificate, form or forms as may be required by the United States Treasury Department as necessary in order to properly avoid withholding of United States federal income tax), for each calendar year in which a payment
is made (but prior to the making of any payment for such year), and has not notified the Mortgagee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Mortgagee has no reason to believe that any
information set forth in such form is inaccurate) or (y) which is a U.S. Person has furnished to the Mortgagee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form
W-9, if applicable, prior to a payment hereunder or under the Equipment Notes held by such holder, no amount shall be withheld from payments in respect of United States federal income tax. If any Note Holder
has notified the Mortgagee that any of the foregoing forms or certificates is withdrawn or inaccurate, or if such holder has not filed a form claiming an exemption from United States withholding tax or if the Code or the regulations thereunder or
the administrative interpretation thereof is at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Equipment Notes held by such holder, the Mortgagee agrees to withhold
from each payment due to the relevant Note Holder withholding taxes at the appropriate rate under Law and will, on a timely basis as more fully provided above, deposit such amounts with an authorized depository and make such returns, statements,
receipts and other documentary evidence in connection therewith as required by Law. 
 Owner shall not have any liability for the failure of
the Mortgagee to withhold taxes in the manner provided for herein or for any false, inaccurate or untrue evidence provided by any Note Holder hereunder. 

SECTION 2.05. Application of Payments 

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

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

  

			
	TRUST INDENTURE 22-1 (A and B)	  	14

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

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

Fourth: the balance, if any, remaining thereafter, to the payment of the Original Amount of such Equipment Note remaining
unpaid (provided that such Equipment Note shall not be subject to redemption except as provided in Sections 2.10, 2.11 and 2.12 hereof). 
 The amounts paid
pursuant to clause “Fourth” above shall be applied to the installments of Original Amount of such Equipment Note in the inverse order of their scheduled maturity. 

SECTION 2.06. Termination of Interest in Collateral 

No Note Holder nor any other Indenture Indemnitee shall, as such, have any further interest in, or other right with respect to, the Collateral
when and if the Original Amount of, Make-Whole Amount, if any, and interest on and other amounts due under all Equipment Notes held by such Note Holder and all other sums then due and payable to such Note Holder, such Indenture Indemnitee or the
Mortgagee hereunder (including, without limitation, under the third paragraph of Section 2.02 hereof) and under the other Operative Agreements by the Owner and all Related Secured Obligations (collectively, the “Secured Obligations”)
shall have been paid in full. 
 SECTION 2.07. Registration Transfer and Exchange of Equipment Notes 

The Mortgagee shall keep a register (the “Equipment Note Register”) in which the Mortgagee shall provide for the registration
of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of
the Mortgagee. The Mortgagee is hereby appointed “Equipment Note Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange such
Equipment Note shall surrender such Equipment Note to the Mortgagee at the Corporate Trust Office, together with a written request from the registered holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender
for transfer, the name and address of the new holder or holders. Upon surrender for registration of transfer of any Equipment Note, the Owner shall execute, and the Mortgagee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Equipment Notes of a like aggregate Original Amount and of the same Series. At the option of the Note Holder, Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a like
aggregate Original Amount, upon surrender of the Equipment Notes to be exchanged to the Mortgagee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner shall execute, and the Mortgagee shall
authenticate and deliver, the Equipment Notes 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	15

 
which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this Section 2.07
or under Section 2.08 hereof or otherwise under this Trust Indenture) shall be the valid obligations of the Owner evidencing the same respective obligations, and entitled to the same security and benefits under this Trust Indenture, as the
Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer, shall (if so required by the Mortgagee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Mortgagee duly executed by the Note Holder or such holder’s attorney duly authorized in writing, and the Mortgagee shall require evidence satisfactory to it as to the compliance of any such
transfer with the Securities Act, and the securities Laws of any applicable state. The Mortgagee shall make a notation on each new Equipment Note of the amount of all payments of Original Amount previously made on the old Equipment Note or Equipment
Notes with respect to which such new Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be deemed to have been paid on such new Equipment Note to the date on which
interest shall have been paid on such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner shall not be required to exchange any
surrendered Equipment Notes as provided above during the ten-day period preceding the due date of any payment on such Equipment Note. The Owner shall in all cases deem the Person in whose name any Equipment
Note shall have been issued and registered as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the Owner with respect to such Equipment Note and for all purposes until a notice
stating otherwise is received from the Mortgagee and such change is reflected on the Equipment Note Register. The Mortgagee will promptly notify the Owner of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment
Note, by its acceptance of an Equipment Note, (i) agrees to the provisions of this Trust Indenture and the Participation Agreement applicable to Note Holders, including Sections 6.3, 6.4 and 9.1 thereof, and shall be deemed to have covenanted
to the parties to the Participation Agreement as to the matters covenanted by the original Note Holder in the Participation Agreement and (ii) agrees to the restrictions set forth in Sections 4.1(a)(i) and 4.1(a)(iii) of the Intercreditor
Agreement, and shall be deemed to have covenanted to the parties to the Intercreditor Agreement not to give any direction, or otherwise authorize, the Mortgagee to take any action that would violate Sections 4.1(a)(i) or 4.1(a)(iii) of the
Intercreditor Agreement. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.07, Mortgagee and Owner shall use all reasonable efforts to issue new Equipment Notes upon transfer or
exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange. 
 SECTION 2.08. Mutilated,
Destroyed, Lost or Stolen Equipment Notes 
 If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner shall,
upon the written request of the holder of such Equipment Note, execute and the Mortgagee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original Amount dated the same date and captioned as issued in
connection with the Aircraft. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Mortgagee and a photocopy thereof shall be furnished to the Owner. If the Equipment Note being replaced has been
destroyed, lost or stolen, the holder of such 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	16

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

SECTION 2.09. Payment of Expenses on Transfer; Cancellation 

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

(b) The Mortgagee shall cancel all Equipment Notes surrendered for replacement, redemption, transfer, exchange, payment or cancellation and
shall destroy the canceled Equipment Notes. 
 SECTION 2.10. Mandatory Redemptions of Equipment Notes 

On the date on which the Owner is required pursuant to Section 4.05 hereof to make payment for an Event of Loss with respect to the
Airframe, all of the Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with all accrued interest thereon to the date of redemption and all other Secured Obligations (other

Section 3.03 and any investment earnings thereon or other Cash Equivalents will be credited to an Eligible Account (the “Securities Account”) for which it is a “securities intermediary” (as defined in Section 8-
102(a)(14) of the NY UCC) and the Mortgagee is the “entitlement holder” (as defined in Section 8-102(a)(7) of the NY UCC) of the “securities entitlement” (as defined in Section 8-102(a)(17) of the NY UCC) with respect to each “financial asset” (as defined in Section 8-102(a)(9) of the NY UCC) credited to such Eligible

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

may be installed (which shall not be considered a transfer of possession hereunder); provided that the Owner’s obligations hereunder shall continue in full force and effect notwithstanding any such charter or Wet Lease or other
similar arrangement; 
 (viii) So long as no Event of Default shall have occurred and be continuing, and subject to the provisions of the
immediately following paragraph, enter into a lease with respect to the Aircraft, Airframe or any Engine to any Permitted Air Carrier that is not then subject to any bankruptcy, insolvency, liquidation, reorganization, dissolution or similar
proceeding and shall not have substantially all of its property in the possession of any liquidator, trustee, receiver or similar person; provided that, in the case only of a lease to a Permitted Foreign Air Carrier, (A) the
United States maintains diplomatic relations with the country of domicile of such Permitted Foreign Air Carrier (or, in the case of Taiwan, diplomatic relations at least as good as those in effect on the Closing Date) and (B) Owner shall have
furnished Mortgagee a favorable opinion of counsel, reasonably satisfactory to Mortgagee, in the country of domicile of such Permitted Foreign Air Carrier, that (v) the terms of such lease are the legal, valid and binding obligations of the
parties thereto enforceable under the laws of such jurisdiction, (w) it is not necessary for Mortgagee to register or qualify to do business in such

jurisdiction, if not already so registered or qualified, as a result, in whole or in part, of the proposed lease, (x) Mortgagee’s Lien in respect of, the Aircraft, Airframe and Engines
will be recognized in such jurisdiction, (y) the Laws of such jurisdiction of domicile require fair compensation by the government of such jurisdiction, payable in a currency freely convertible into Dollars, for the loss of title to the
Aircraft, Airframe or Engines in the event of the requisition by such government of such title (unless Owner shall provide insurance in the amounts required with respect to hull insurance under this Trust Indenture covering the requisition of title
to the Aircraft, Airframe or Engines by the government of such jurisdiction so long as the Aircraft, Airframe or Engines are subject to such lease) and (z) the agreement of such Permitted Air Carrier that its rights under the lease are subject
and subordinate to all the terms of this Trust Indenture is enforceable against such Permitted Air Carrier under applicable law; 
 provided that
(1) the rights of any transferee who receives possession by reason of a transfer permitted by any of clauses (i) through (viii) of this Section 4.02(b) (other than by a transfer of an Engine which is deemed an Event of Loss)
shall be subject and subordinate to all the terms of this Trust Indenture, (2) the Owner shall remain primarily liable for the performance of all of the terms of this Trust Indenture and all the terms and conditions of this Trust Indenture and
the other Operative Agreements shall remain in effect and (3) no lease or transfer of possession otherwise in compliance with this Section 4.02(b) shall (x) result in any registration or

a lease to a U.S. Air Carrier to be given promptly after entering into any such lease or, in the case of a lease to any other Permitted Air Carrier, 10 days in advance of entering into such lease); (x) Owner shall furnish to Mortgagee evidence
reasonably satisfactory to Mortgagee that the insurance required by Section 4.06 remains in effect; (y) all necessary documents shall have been duly filed, registered or recorded in such public offices as may be required fully to preserve
the first priority security interest and International Interest (subject to Permitted Liens) of Mortgagee in the Aircraft, Airframe and Engines; and (z) Owner shall reimburse Mortgagee for all of its reasonable out-of-pocket fees and expenses, including, without limitation, reasonable fees and disbursements of counsel, incurred by Mortgagee in connection with any such lease. Except as otherwise provided herein and
without in any way relieving the Owner from its primary obligation for the performance of its obligations under this Trust Indenture, the Owner may in its sole discretion permit a lessee to exercise any or all rights which the Owner would be
entitled to exercise under Sections 4.02 and 4.04, and may cause a lessee to perform any or all of the Owner’s obligations under Article IV, and the Mortgagee agrees to accept actual and full performance thereof by a lessee in lieu of
performance by the Owner. 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	29

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

(c) Operation and Use. So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall
not operate, use or locate the Aircraft, Airframe or any Engine, or allow the Aircraft, Airframe or any Engine to be operated, used or located, (i) in any area excluded from coverage by any insurance required by the terms of Section 4.06,
except in the case of a requisition by the U.S. Government where the Owner obtains indemnity in lieu of such insurance from the U.S. Government, or insurance from the U.S. Government, against substantially the same risks and for at least the amounts
of the insurance required by Section 4.06 covering such area, or (ii) in any recognized area of hostilities unless covered in accordance with Section 4.06 by war risk insurance, or in either case unless the Aircraft, the Airframe or
any Engine is only temporarily operated, used or located in such area as a result of an emergency, equipment malfunction, navigational error, hijacking, weather condition or other similar unforeseen circumstance, so long as Owner diligently and in
good faith proceeds to remove the Aircraft from such area. So long as the Aircraft, the Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not permit such Aircraft, Airframe or any Engine, as the case may be, to
be used, operated, maintained, serviced, repaired or overhauled (x) in violation of any Law binding on or applicable to such Aircraft, Airframe or Engine or (y) in violation of any airworthiness certificate, license or registration of any
Government Entity relating to the Aircraft, the Airframe or any Engine, except (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by Owner or Permitted
Lessee, as the case may be, upon discovery thereof, or (ii) to the extent the validity or application of any such Law or requirement relating to any such certificate, license or registration is being contested in good faith by Owner or
Permitted Lessee in any reasonable manner which does not involve any material risk of the sale, forfeiture or loss of the Aircraft, Airframe or any Engine, any material risk of criminal liability or material civil penalty against Mortgagee or impair
the Mortgagee’s security interest or International Interest in the Aircraft, Airframe or any Engine. 
 (d) Maintenance and
Repair. So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall cause the Aircraft, Airframe and each Engine to be maintained, serviced, repaired and overhauled in accordance with
(i) maintenance standards required by or substantially equivalent to those required by the FAA, the EASA or the central aviation authority of Canada or Japan for the Aircraft, Airframe and Engines, so as to (A) keep the Aircraft, the
Airframe and each Engine in as good operating condition as on the Closing Date, ordinary wear and tear excepted, (B) keep the Aircraft in such operating condition as may be necessary to enable the applicable airworthiness certification of

  

			
	TRUST INDENTURE 22-1 (A and B)	  	30

 
such Aircraft to be maintained under the regulations of the FAA or other Aviation Authority then having jurisdiction over the operation of the Aircraft, except during (x) temporary periods
of storage in accordance with applicable regulations, (y) maintenance and modification permitted hereunder or (z) periods when the FAA or such other Aviation Authority has revoked or suspended the airworthiness certificates for Similar
Aircraft; and (ii) except during periods when a Permitted Lease is in effect, the same standards as Owner uses with respect to similar aircraft of similar size in its fleet operated by Owner in similar circumstances and, during any period in
which a Permitted Lease is in effect, the same standards used by the Permitted Lessee with respect to similar aircraft of similar size in its fleet and operated by the Permitted Lessee in similar circumstances (it being understood that this clause
(ii) shall not limit Owner’s obligations under the preceding clause (i)). Owner further agrees that the Aircraft, Airframe and Engines will be maintained, used, serviced, repaired, overhauled or inspected in compliance with applicable Laws
with respect to the maintenance of the Aircraft and in compliance with each applicable airworthiness certificate, license and registration relating to the Aircraft, Airframe or any Engine issued by the Aviation Authority, other than minor or
nonrecurring violations with respect to which corrective measures are taken upon discovery thereof and except to the extent Owner or Permitted Lessee is contesting in good faith the validity or application of any such Law or requirement relating to
any such certificate, license or registration in any reasonable manner which does not create a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any Engine or the interest of Mortgagee therein, or any material risk of
criminal liability or material civil penalty against Mortgagee. The Owner shall maintain or cause to be maintained the Aircraft Documents in the English language. 

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

  

			
	TRUST INDENTURE 22-1 (A and B)	  	31

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

SECTION 4.03. Inspection 

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

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

(c) With respect to such rights of inspection, Mortgagee shall not have any duty or liability to make, or any duty or liability by reason of
not making, any such visit, inspection or survey. 
 (d) Each Inspecting Party shall bear its own expenses in connection with any such
inspection (including the cost of any copies made in accordance with Section 4.03(a)). 
 SECTION 4.04. Replacement and Pooling
of Parts, Alterations, Modifications and Additions; Substitution Rights 
 (a) Replacement of Parts. Except as otherwise
provided herein, so long as the Airframe or Engine is subject to the Lien of this Indenture, Owner, at its own cost and expense, will, or will cause a Permitted Lessee to, at its own cost and expense, promptly replace (or cause to be replaced) all
Parts which may from time to time be incorporated or installed in or attached to the Aircraft, Airframe or any Engine and which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently
rendered unfit for use for any reason whatsoever. In addition, Owner may, at its own cost and expense, or may permit a Permitted Lessee at its own cost and expense to, remove (or cause to be removed) in the ordinary course of maintenance, service,
repair, overhaul or testing any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use; provided, however, that Owner, except as otherwise provided
herein, at its own cost and expense, will, or will cause a Permitted Lessee at its own cost and expense to, replace such Parts as promptly as practicable. All replacement parts shall be free and clear of all Liens, except for Permitted Liens and
pooling arrangements to the extent permitted by Section 4.04(c) below (and except in the case of replacement property temporarily installed on an emergency basis) and shall be in good operating condition and have a value and utility not less
than the value and utility of the Parts replaced (assuming such replaced Parts were in the condition required hereunder). 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	32

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

(c) Pooling of Parts. Any Part removed from the Aircraft, Airframe or an Engine may be subjected by the Owner or a Permitted Lessee to
a normal pooling arrangement customary in the airline industry and entered into in the ordinary course of business of Owner or Permitted Lessee, provided that the part replacing such removed Part shall be incorporated or installed in or attached to
such Airframe or any Engine in accordance with Sections 4.04(a) and 4.04(b) as promptly as practicable after the removal of such removed Part. In addition, any replacement part when incorporated or installed in or attached to the Airframe or any
Engine may be owned by any third party, subject to a normal pooling arrangement, so long as the Owner or a Permitted Lessee, at its own cost and expense, as promptly thereafter as reasonably possible, either (i) causes such replacement part to
become subject to the Lien of this Trust Indenture, free and clear of all Liens except Permitted Liens, at which time such replacement part shall become a Part or (ii) replaces (or causes to be replaced) such replacement part by incorporating
or installing in or attaching to the Aircraft, Airframe or any Engine a further replacement part owned by the Owner free and clear of all Liens except Permitted Liens and which shall become subject to the Lien of this Trust Indenture in accordance
with Section 4.04(b). 
 (d) Alterations, Modifications and Additions. The Owner shall, or shall cause a Permitted Lessee to,
make (or cause to be made) alterations and modifications in and additions to the Aircraft, Airframe and each Engine as may be required to be made from time to time to meet the applicable standards of the FAA or other Aviation Authority having
jurisdiction over the operation of the Aircraft, to the extent made mandatory in respect of the Aircraft; provided however, that the Owner or a Permitted Lessee may, in good faith and by appropriate procedure, contest the validity or
application of any law, rule, regulation or order in any reasonable manner which does not materially adversely affect Mortgagee’s interest in the Aircraft, does not impair the Mortgagee’s security interest or International Interest in the
Aircraft and does not involve any material risk of sale, forfeiture or loss of the Aircraft or the interest of Mortgagee therein, or any material risk of material civil penalty or any material risk of criminal liability being imposed on Mortgagee or
the holder of any Equipment Note. In addition, the Owner, at its own expense, may, or may permit a Permitted Lessee at its own cost and expense to, from time to time make or cause to be made such alterations and modifications in and additions to the
Airframe or any Engine (each an “Optional Modification”) as the Owner or such 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	33

 
Permitted Lessee may deem desirable in the proper conduct of its business including, without limitation, removal of Parts which Owner deems are obsolete or no longer suitable or appropriate for
use in the Aircraft, Airframe or such Engine; provided, however, that no such Optional Modification shall (i) materially diminish the fair market value, utility, or useful life of the Aircraft or any Engine below its fair market
value, utility or useful life immediately prior to such Optional Modification (assuming the Aircraft or such Engine was in the condition required by this Trust Indenture immediately prior to such Optional Modification) or (ii) cause the
Aircraft to cease to have the applicable standard certificate of airworthiness except that such certificate of airworthiness temporarily may be replaced by an experimental certificate during the process of implementing and testing such Optional
Modification and securing related FAA re-certification of the Aircraft. All Parts incorporated or installed in or attached to any Airframe or any Engine as the result of any alteration, modification or
addition effected by the Owner shall be free and clear of any Liens except Permitted Liens and become subject to the Lien of this Trust Indenture; provided that the Owner or any Permitted Lessee may, at any time so long as the Airframe or any
Engine is subject to the Lien of this Trust Indenture, remove any such Part (such Part being referred to herein as a “Removable Part”) from such Airframe or an Engine if (i) such Part is in addition to, and not in replacement of or in
substitution for, any Part originally incorporated or installed in or attached to such Airframe or any Engine at the time of delivery thereof hereunder or any Part in replacement of, or in substitution for, any such original Part, (ii) such
Part is not required to be incorporated or installed in or attached or added to such Airframe or any Engine pursuant to the terms of Section 4.02(d) or the first sentence of this Section 4.04(d) and (iii) such Part can be removed from
such Airframe or any Engine without materially diminishing the fair market value, utility or remaining useful life which such Airframe or any Engine would have had at the time of removal had such removal not been effected by the Owner, assuming the
Aircraft was otherwise maintained in the condition required by this Trust Indenture and such Removable Part had not been incorporated or installed in or attached to the Aircraft, Airframe or such Engine. Upon the removal by the Owner of any such
Part as above provided in this Section 4.04(d), title thereto shall, without further act, be free and clear of all rights of the Mortgagee and such Part shall no longer be deemed a Part hereunder. Removable Parts may be leased from or financed
by third parties other than Mortgagee. 
 (e) Substitution of Engines. Upon the occurrence of an Event of Loss with respect to an
Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, Owner shall promptly (and in any event within 15 days after such occurrence) give the Mortgagee written notice of such Event of Loss. The Owner shall
have the right at its option at any time, on at least five Business Days’ prior notice to the Mortgagee, to substitute, and if an Event of Loss shall have occurred with respect to an Engine under circumstances in which an Event of Loss with
respect to the Airframe has not occurred, shall within 60 days of the occurrence of such Event of Loss substitute, a Replacement Engine for any Engine. In such event, immediately upon the effectiveness of such substitution and without further act,
(i) the replaced Engine shall thereupon be free and clear of all rights of the Mortgagee and the Lien of this Trust Indenture and shall no longer be deemed an Engine hereunder and (ii) such Replacement Engine shall become subject to this
Trust Indenture and be deemed part of the Aircraft for all purposes hereof to the same extent as the replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer or another manufacturer that is the same model as
the Engine to be replaced thereby, or a comparable or 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	34

 
improved model, and that is suitable for installation and use on the Airframe, and that has a value and utility (without regard to hours and cycles) at least equal to the Engine to be replaced
thereby (assuming that such Engine had been maintained in accordance with this Trust Indenture). The Owner’s right to make a replacement hereunder shall be subject to the fulfillment (which may be simultaneous with such replacement) of the
following conditions precedent at the Owner’s sole cost and expense, and the Mortgagee agrees to cooperate with the Owner to the extent necessary to enable it to timely satisfy such conditions: 

(i) an executed counterpart of each of the following documents shall be delivered to the Mortgagee: 

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

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

(C) UCC financing statements covering the security interests created by this Trust Indenture (or any similar statements or
other documents required to be filed or delivered pursuant to the laws of the jurisdiction in which such Aircraft may be registered) as are deemed necessary or desirable by counsel for the Mortgagee to protect the security interests of the Mortgagee
in the Replacement Engine; 
 (ii) the Owner shall cause to be delivered to the Mortgagee an opinion of counsel to the effect that the Lien
of this Trust Indenture continues to be in full force and effect with respect to the Replacement Engine and such evidence of compliance with the insurance provisions of Section 4.06 with respect to such Replacement Engine as Mortgagee shall
reasonably request; 
 (iii) the Owner shall have furnished to Mortgagee an opinion of Owner’s aviation law counsel reasonably
satisfactory to Mortgagee and addressed to Mortgagee as to the due filing for recordation of the Trust Indenture Supplement with respect to such Replacement Engine under the Act or such other applicable law of the jurisdiction other than the United
States in which the Aircraft is registered in accordance with Section 4.02(e), as the case may be, and the registration (which Owner shall have caused to be effected) with the International Registry of the sale to Owner of such Replacement
Engine (if occurring after February 28, 2006) and the International Interest granted under such Trust Indenture Supplement with respect to such Replacement Engine; and 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	35

 (iv) the Owner shall have furnished to Mortgagee a certificate of a qualified aircraft
engineer (who may be an employee of Owner) certifying that such Replacement Engine has a value and utility (without regard to hours and cycles) at least equal to the Engine so replaced (assuming that such Engine had been maintained in accordance
with this Trust Indenture). 
 Upon satisfaction of all conditions to such substitution, (x) the Mortgagee shall execute and deliver to the Owner such
documents and instruments, prepared at the Owner’s expense, as the Owner shall reasonably request to evidence the release of such replaced Engine from the Lien of this Trust Indenture, (y) the Mortgagee shall assign to the Owner all claims
it may have against any other Person relating to any Event of Loss giving rise to such substitution and (z) the Owner shall receive all insurance proceeds (other than those reserved to others under Section 4.06(b)) and proceeds in respect
of any Event of Loss giving rise to such replacement to the extent not previously applied to the purchase price of the Replacement Engine as provided in Section 4.05(d). 

(f) Substitution of Airframe. Owner shall have the right at its option at any time, on at least 10 Business Days’ prior written
notice to the Mortgagee, to substitute one or more Substitute Airframes, 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 shall be of the same model as the Airframe or a Boeing model 737-700 aircraft or a Boeing model 737-900ER aircraft,
(iii) each 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 Trust 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 applicable airframe manufacturer), (iv) the Substitute Airframe has a MCMV (as defined below) (or, in the case of multiple Substitute Airframes, the sum of
the MCMVs of such Substitute Airframes shall be) at least equal to the MCMV of the Airframe, plus the “MCMVs” of each applicable airframe under Section 4.04(f) of any Related Indenture, being replaced by the Substitute Airframes
(assuming that the Airframe had been maintained in accordance with this Trust 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 independent aircraft appraiser experienced in valuing commercial aircraft selected by Owner and (v) Owner shall have obtained Rating Agency Confirmation in respect of the substitution of the Airframe by such Substitute
Airframes. “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 Owner 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 the effectiveness of any such substitution of any Substitute Airframe for the Airframe on other than a
one for one basis pursuant to this Section 4.04(f), Owner shall prepare amendments to this Trust Indenture (including the Schedules, Annexes and Exhibits hereto), in order to make the reasonably necessary changes arising from such substitution,
including, if applicable, providing for separate financing agreements substantially the same as the Operative Agreements with respect to each such Substitute Airframe and the allocation among such Substitute Airframes of the principal amount of the
Equipment Notes (and any applicable Related Equipment Notes) and remaining amortization schedule relating to the Airframe (or 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	36

 
relating to any applicable airframe under Section 4.04(f) of any Related Indenture) pro rata based on the MCMV of each Substitute Airframe or on such other basis among each Substitute
Airframe determined in a manner consistent with, and as would preserve the aggregate amortization profile of, the original Equipment Notes). Owner shall submit such proposed amendments to the Rating Agencies in connection with Owner’s request
for the Rating Agency Confirmation with respect to such substitution and the Mortgagee shall execute and deliver such amendments upon Owner’s request. 

Prior to or at the time of any substitution under this Section 4.04(f), Owner will (A) cause a Trust Indenture Supplement covering
such Substitute Airframe to be filed for recordation pursuant to the Act 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 Owner (if occurring after
February 28, 2006) and the International Interest created pursuant to the Trust Indenture Supplement in favor of the Mortgagee with respect to such Substitute Airframe to be registered on the International Registry as a sale or an International
Interest, respectively, (C) cause a UCC financing statement or statements with respect to the security interests created by this Trust Indenture in such Substitute Airframe or other requisite documents or instruments to be filed in such place
or places as necessary in order to perfect the Mortgagee’s security interest therein in the United States, or in any other jurisdiction in which the Aircraft may then be registered, (D) furnish the Mortgagee with an opinion of counsel to
Owner (which may be external counsel or Owner’s legal department or such other internal counsel of Owner as shall be reasonably satisfactory to the Mortgagee) addressed to the Mortgagee to the effect that upon such substitution, such Substitute
Airframe will be subject to the Lien of this Trust Indenture and addressing the matters set forth in clauses (A) and (B), (E) furnish the Mortgagee with evidence of compliance with the insurance provisions of Section 4.06 with respect to
such Substitute Airframe, (F) furnish the Mortgagee with a copy of a bill of sale respecting the conveyance to Owner of such Substitute Airframe and (G) furnish the Mortgagee with an opinion of counsel to Owner (which may be external
counsel or Owner’s legal department or such other internal counsel of Owner as shall be reasonably satisfactory to the Mortgagee) to the effect that the Mortgagee 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 the Mortgagee
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 Owner delivered pursuant to Section 4.1.2(x) 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 Trust Indenture under this Section 4.04(f), promptly upon the
recordation of the Trust Indenture Supplement covering such Substitute Airframe pursuant to the Act (or pursuant to the applicable law of such other jurisdiction in which such Substitute Airframe is registered), Owner will cause to be delivered to
the Mortgagee a favorable opinion of aviation law counsel to Owner (which may be external aviation law counsel or Owner’s legal department or such other internal counsel of Owner as shall be reasonably satisfactory to the Mortgagee) addressed
to the Mortgagee as to the due registration of the Replacement Aircraft (after giving effect to the substitution of such Substitute Airframe) and the due recordation of such Trust Indenture Supplement pursuant to the Act. 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	37

 For all purposes hereof, upon the attachment of the Lien of this Trust Indenture thereto,

replaced Airframe and (y) provide a notice to the Note Holders setting forth (1) the date of the substitution which shall be the date of filing of the Trust Indenture Supplement described in clause (A) of the second preceding
paragraph, (2) the model of the Substitute Airframe, (3) the manufacturer serial numbers of the Substitute Airframe and Airframe replaced by the Substitute Airframe, and (4) the registration numbers of the Replacement Aircraft of
which the Substitute Airframe is a part and the Aircraft of which the Airframe replaced by the Substitute Airframe is part. 
 SECTION

written notice of Owner’s election to either replace the Airframe as provided under Section 4.05(a)(i) or to make payment in respect of such Event of Loss as provided under Section 4.05(a)(ii) (it being agreed that if Owner shall not

Liens and to have a value and utility (without regard to hours or cycles) at least equal to the Airframe or Engine, as the case may be, to be replaced thereby (assuming that such Airframe or Engine had been maintained in accordance with this Trust
Indenture); provided that if the Owner shall not perform its obligation to effect such replacement under this clause (i) during the 120-day period of time provided herein, it shall pay the
amounts required to be paid pursuant to and within the time frame specified in clause (ii) below; or

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

expense of the Owner, release from the Lien of this Trust Indenture the replaced Airframe and Engines, if any, by executing and delivering to the Owner such documents and instruments as the Owner may reasonably request to evidence such release; and

(other than those reserved to others under Section 4.06(b)) and proceeds from any award in respect of condemnation, confiscation, seizure or requisition, including any investment interest thereon, to the extent not previously applied to the
purchase price of the Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(d). 
 (c) Conditions to
Airframe and Engine Replacement. The Owner’s right to substitute a Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(a)(i) shall be subject to the fulfillment, at the Owner’s sole cost and expense,

	TRUST INDENTURE 22-1 (A and B)	  	40

 
opinion of Owner’s aviation law counsel reasonably satisfactory to and addressed to Mortgagee as to the due registration of any such Replacement Airframe and the due filing for recordation

in accordance with Section 4.02(e), as the case may be, and the registration with the International Registry of the sale of such Replacement Airframe and Replacement Engine(s), if any, to the Owner (if occurring after February 28, 2006)
and of the International Interest granted under the Trust Indenture Supplement with respect to such Replacement Aircraft and Replacement Engine(s), if any; and

	TRUST INDENTURE 22-1 (A and B)	  	41

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

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

SECTION 4.06. Insurance 

(a) Owner’s Obligation to Insure. Owner shall comply with, or cause to be complied with, each of the provisions of Annex B,
which provisions are hereby incorporated by this reference as if set forth in full herein. 
 (b) Insurance for Own Account. Nothing
in Section 4.06 shall limit or prohibit (a) Owner from maintaining the policies of insurance required under Annex B with higher limits than those specified in Annex B, or (b) Mortgagee from obtaining insurance for its own account (and
any proceeds payable under such separate insurance shall be payable as provided in the policy relating thereto); provided, however, that no insurance may be obtained or maintained that would limit or otherwise adversely affect the
coverage of any insurance required to be obtained or maintained by Owner pursuant to this Section 4.06 and Annex B. 
 (c)
Indemnification by Government in Lieu of Insurance. Mortgagee agrees to accept, in lieu of insurance against any risk with respect to the Aircraft described in Annex B, indemnification from, or insurance provided by, the U.S. Government, or
upon the written consent of Mortgagee, other Government Entity, against such risk in an amount that, when added to the amount of insurance (including permitted self-insurance), if any, against such risk that Owner (or any Permitted Lessee) may
continue to maintain, in accordance with this Section 4.06, during the period of such requisition or transfer, shall be at least equal to the amount of insurance against such risk otherwise required by this Section 4.06; provided
that the provisions of Section D of Annex B shall not apply to an indemnity or insurance provided by the U.S. Government in lieu of insurance required by Section C of Annex B, except to the extent the U.S. Government makes such provisions generally
available to covered airlines. 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	42

 (d) Application of Insurance Proceeds. As between Owner and Mortgagee, all insurance
proceeds received as a result of the occurrence of an Event of Loss with respect to the Aircraft or any Engine under policies required to be maintained by Owner pursuant to this Section 4.06 will be applied in accordance with
Section 4.05(d). All proceeds of insurance required to be maintained by Owner, in accordance with Section 4.06 and Section B of Annex B, in respect of any property damage or loss not constituting an Event of Loss with respect to
the Aircraft, Airframe or any Engine will be applied in payment (or to reimburse Owner) for repairs or for replacement property, and any balance remaining after such repairs or replacement with respect to such damage or loss shall be paid over to,
or retained by, Owner. 
 SECTION 4.07. Merger of Owner 

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

(i) such person is organized, existing and in good standing under the Laws of the United States, any State of the United States or the
District of Columbia and, upon consummation of such transaction, such person will be a U.S. Air Carrier; 
 (ii) such person executes and
delivers to Mortgagee a duly authorized, legal, valid, binding and enforceable agreement, reasonably satisfactory in form and substance to Mortgagee, containing an effective assumption by such person of the due and punctual performance and
observance of each covenant, agreement and condition in the Operative Agreements to be performed or observed by Owner; 
 (iii) if the
Aircraft is, at the time, registered with the FAA, such person makes such filings and recordings with the FAA pursuant to the Act or if the Aircraft is, at the time, not registered with FAA, such person makes such filings and recordings with the
applicable Aviation Authority as shall be necessary to evidence such consolidation or merger; 
 (iv) such person makes such registrations
with the International Registry as shall be permitted to evidence such consolidation or merger; and 
 (v) immediately after giving effect
to such consolidation or merger no Event of Default shall have occurred and be continuing. 
 (b) Effect of Merger. Upon any such
consolidation or merger of Owner with or into, or the conveyance, transfer or lease by Owner of all or substantially all of its assets to, any Person in accordance with this Section 4.07, such Person will succeed to, and be substituted for, and
may exercise every right and power of, Owner under the Operative Agreements with the same effect as if such person had been named as “Owner” therein. No such consolidation or merger, or conveyance, transfer or lease, shall have the effect
of releasing Owner or such Person from any of the obligations, liabilities, covenants or undertakings of Owner under this Trust Indenture.

SECTION 5.02. Remedies 

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

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

  

			
	TRUST INDENTURE 22-1 (A and B)	  	45

 
protest or notice, all of which are hereby waived; provided that if an Event of Default referred to in clause (v), (vi) or (vii) of Section 5.01 hereof shall have occurred, then and in
every such case the unpaid Original Amount then outstanding, together with accrued but unpaid interest (without Make-Whole Amount) and all other amounts due hereunder and under the Equipment Notes shall immediately and without further act become due
and payable without presentment, demand, protest or notice, all of which are hereby waived. 
 This Section 5.02(b), however, is
subject to the condition that, if at any time after the Original Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered, all overdue
payments of interest upon the Equipment Notes and all other amounts payable hereunder or under the Equipment Notes (except the Original Amount of the Equipment Notes and any Make-Whole Amount which by such declaration shall have become payable)
shall have been duly paid, and every other Default and Event of Default with respect to any covenant or provision of this Trust Indenture shall have been cured, then and in every such case a Majority in Interest of Note Holders may (but shall not be
obligated to), by written instrument filed with the Mortgagee, rescind and annul the Mortgagee’s declaration (or such automatic acceleration) and its consequences; but no such rescission or annulment shall extend to or affect any subsequent
Default or Event of Default or impair any right consequent thereon. 
 (c) The Note Holders shall be entitled, at any sale pursuant to this
Section 5.02, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (only to the extent that such purchase price
would have been paid to such Note Holder pursuant to Article III hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c) were not given effect). 

(d) In the event of any sale of the Collateral, or any part thereof, pursuant to any judgment or decree of any court or otherwise in
connection with the enforcement of any of the terms of this Trust Indenture, the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued interest thereon (without Make-Whole Amount), and other amounts due thereunder,
shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived. 
 (e)
Notwithstanding anything contained herein, so long as the Pass Through Trustee under any Pass Through Trust Agreement (or its designee) is a Note Holder, the Mortgagee will not be authorized or empowered to acquire title to any Collateral or take
any action with respect to any Collateral so acquired by it if such acquisition or action would cause any Trust to fail to qualify as a “grantor trust” for federal income tax purposes. 

SECTION 5.03. Return of Aircraft, Etc. 

(a) If an Event of Default shall have occurred and be continuing and the Equipment Notes have been accelerated, at the request of the
Mortgagee, the Owner shall promptly execute and deliver to the Mortgagee such instruments of title and other documents as the Mortgagee may deem necessary or advisable to enable the Mortgagee or an agent or

  

			
	TRUST INDENTURE 22-1 (A and B)	  	46

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

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

 SECTION 5.04. Remedies Cumulative 

Each and every right, power and remedy given to the Mortgagee specifically or otherwise in this Trust Indenture shall be cumulative and shall
be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at Law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may be
exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the
same time or thereafter any other right, power or remedy. No delay or omission by the Mortgagee in the exercise of any right, remedy or power or in the pursuance of any remedy shall impair any such right, power or remedy or be construed to be a
waiver of any default on the part of the Owner or to be an acquiescence therein. 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	47

 SECTION 5.05. Discontinuance of Proceedings 

In case the Mortgagee shall have instituted any proceeding to enforce any right, power or remedy under this Trust Indenture by foreclosure,
entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Mortgagee, then and in every such case the Owner and the Mortgagee shall, subject to any determination
in such proceedings, be restored to their former positions and rights hereunder with respect to the Collateral, and all rights, remedies and powers of the Owner or the Mortgagee shall continue as if no such proceedings had been instituted. 

SECTION 5.06. Waiver of Past Defaults 

Upon written instruction from a Majority in Interest of Note Holders, the Mortgagee shall waive any past Default hereunder and its
consequences and upon any such waiver such Default shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Trust Indenture, but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon; provided, that in the absence of written instructions from all the Note Holders, the Mortgagee shall not waive any Default (i) in the payment of the Original Amount, Make-Whole Amount, if
any, and interest and other amounts due under any Equipment Note then outstanding, or (ii) in respect of a covenant or provision hereof which, under Article X hereof, cannot be modified or amended without the consent of each Note Holder. The
Mortgagee shall notify the Rating Agency of any such waiver of past Default. 
 SECTION 5.07. Appointment of Receiver 

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

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

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

 ARTICLE VI 

DUTIES OF THE MORTGAGEE 

SECTION 6.01. Notice of Event of Default 

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

SECTION 6.02. Action Upon Instructions; Certain Rights and Limitations 

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

  

			
	TRUST INDENTURE 22-1 (A and B)	  	49

 The Mortgagee will execute and the Owner will file such continuation statements with respect
to financing statements relating to the security interest created hereunder in the Collateral as may be specified from time to time in written instructions of a Majority in Interest of Note Holders (which instructions shall be accompanied by the
form of such continuation statement so to be filed). The Mortgagee will furnish to each Note Holder, promptly upon receipt thereof, duplicates or copies of all reports, notices, requests, demands, certificates and other instruments furnished to the
Mortgagee hereunder. 
 SECTION 6.03. Indemnification 

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

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

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

 SECTION 6.05. No Action Except Under Trust Indenture or Instructions 

The Mortgagee will not use, operate, store, lease, control, manage, sell, dispose of or otherwise deal with the Aircraft or any other part of
the Collateral except in accordance with the powers granted to, or the authority conferred upon the Mortgagee pursuant to this Trust Indenture and in accordance with the express terms hereof. 

SECTION 6.06. Investment of Amounts Held by Mortgagee 

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

The Mortgagee accepts the duties hereby created and applicable to it and agrees to perform the same but only upon the terms of this Trust
Indenture and agrees to receive and disburse all monies constituting part of the Collateral in accordance with the terms hereof. The Mortgagee, in its individual capacity, shall not be answerable or accountable under any circumstances, except
(i) for its own willful misconduct or gross negligence (other than for the handling of funds, for which the standard of accountability shall be willful misconduct or negligence), (ii) as provided in the fourth sentence of Section 2.04(a)

Except in accordance with written instructions furnished pursuant to Section 6.01 or 6.02 hereof, and except as provided in, and without
limiting the generality of, Sections 6.03, 6.04 and 7.07 hereof the Mortgagee shall have no duty (i) to see to any registration of the Aircraft or any recording or filing of this Trust Indenture or any other document, or to see to the
maintenance of any such registration, recording or filing, (ii) to see to any insurance on the Aircraft or to effect or maintain any such insurance, whether or not Owner shall be in default with respect thereto, (iii) to see to the payment
or discharge of any lien or encumbrance of any kind against any part of the Collateral, (iv) to confirm, verify or inquire into the failure to receive any financial statements from Owner, or (v) to inspect the Aircraft at any time or
ascertain or inquire as to the performance or observance of any of Owner’s covenants herein or any Permitted Lessee’s covenants under any assigned Permitted Lease with respect to the Aircraft. 

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

THE MORTGAGEE IN ITS INDIVIDUAL OR TRUST CAPACITY DOES NOT MAKE AND SHALL NOT BE DEEMED TO HAVE MADE AND HEREBY EXPRESSLY DISCLAIMS ANY
REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE TITLE, AIRWORTHINESS, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, DESIGN, QUALITY, DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR USE FOR A PARTICULAR PURPOSE OF THE AIRCRAFT OR
ANY ENGINE, AS TO THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, AS TO THE ABSENCE OF OBLIGATIONS BASED ON STRICT LIABILITY IN TORT OR ANY OTHER
REPRESENTATION OR WARRANTY WHATSOEVER. The Mortgagee, in its individual or trust capacities, does not make or shall not be deemed to have made any representation or warranty as to the validity, legality or enforceability of this Trust Indenture, the
Participation Agreement, or the Equipment Notes, or as to the correctness of any statement contained in any thereof, except for the representations and warranties of the Owner made in its individual capacity and the representations and warranties of
the Mortgagee in its individual capacity, in each case expressly made in this Trust Indenture or in the Participation Agreement. The Note Holders make no representation or warranty hereunder whatsoever. 

SECTION 7.04. No Segregation of Monies; No Interest 

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

  

			
	TRUST INDENTURE 22-1 (A and B)	  	52

 SECTION 7.05. Reliance; Agreements; Advice of Counsel 

The Mortgagee shall not incur any liability to anyone in acting upon any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to be genuine and believed by it to be signed by the proper party or parties. The Mortgagee may accept a copy of a resolution of the Board of Directors (or Executive
Committee thereof) of the Owner, certified by the Secretary or an Assistant Secretary thereof as duly adopted and in full force and effect, as conclusive evidence that such resolution has been duly adopted and that the same is in full force and
effect. As to the aggregate unpaid Original Amount of Equipment Notes outstanding as of any date, the Owner may for all purposes hereof rely on a certificate signed by any Vice President or other authorized corporate trust officer of the Mortgagee.
As to any fact or matter relating to the Owner the manner of the ascertainment of which is not specifically described herein, the Mortgagee may for all purposes hereof rely on a certificate, signed by a duly authorized officer of the Owner, as to
such fact or matter, and such certificate shall constitute full protection to the Mortgagee for any action taken or omitted to be taken by it in good faith in reliance thereon. In the administration of the trusts hereunder, the Mortgagee may execute
any of the trusts or powers hereof and perform its powers and duties hereunder directly or through agents or attorneys and may, at the expense of the Collateral, advise with counsel, accountants and other skilled persons to be selected and retained
by it, and the Mortgagee shall not be liable for anything done, suffered or omitted in good faith by it in accordance with the written advice or written opinion of any such counsel, accountants or other skilled persons.

Owner, and shall have the right, on and subsequent to an Event of Default hereunder, to use or apply any monies held by it hereunder in the Collateral toward such payments. The Mortgagee agrees that it shall have no right against the Note Holders
for any fee as compensation for its services as trustee under this Trust Indenture. 
 SECTION 7.07. Instructions from Note Holders

 In the administration of the trusts created hereunder, the Mortgagee shall have the right to seek instructions from a Majority in

 ARTICLE IX 

SUCCESSOR AND SEPARATE TRUSTEES 

SECTION 9.01. Resignation of Mortgagee; Appointment of Successor 

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

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

  

			
	TRUST INDENTURE 22-1 (A and B)	  	54

 (c) Any successor Mortgagee, however appointed, shall be a bank or trust company having its
principal place of business in the Borough of Manhattan, City and State of New York; Chicago, Illinois; Hartford, Connecticut; Wilmington, Delaware; or Boston, Massachusetts and having (or whose obligations under the Operative Agreements are
guaranteed by an affiliated entity having) a combined capital and surplus of at least $100,000,000, if there be such an institution willing, able and legally qualified to perform the duties of the Mortgagee hereunder upon reasonable or customary
terms. 
 (d) Any corporation into which the Mortgagee may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Mortgagee shall be a party, or any corporation to which substantially all the corporate trust business of the Mortgagee may be transferred, shall, subject to the terms of paragraph
(c) of this Section 9.01, be a successor Mortgagee and the Mortgagee under this Trust Indenture without further act. 
 (e) The
Owner consents to any change in the identity of the Mortgagee on the International Registry occasioned by provisions of this Section 9.01, and if required by the International Registry to reflect such change, will provide its consent thereto.

 SECTION 9.02. Appointment of Additional and Separate Trustees 

(a) Whenever (i) the Mortgagee shall deem it necessary or desirable in order to conform to any Law of any jurisdiction in which all or
any part of the Collateral shall be situated or to make any claim or bring any suit with respect to or in connection with the Collateral, this Trust Indenture, any other Indenture Agreement, the Equipment Notes or any of the transactions
contemplated by the Participation Agreement, (ii) the Mortgagee shall be advised by counsel satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the Mortgagee shall so advise the Owner), or
(iii) the Mortgagee shall have been requested to do so by a Majority in Interest of Note Holders, then in any such case, the Mortgagee and, upon the written request of the Mortgagee, the Owner, shall execute and deliver an indenture
supplemental hereto and such other instruments as may from time to time be necessary or advisable either (1) to constitute one or more bank or trust companies or one or more persons approved by the Mortgagee, either to act jointly with the
Mortgagee as additional trustee or trustees of all or any part of the Collateral, or to act as separate trustee or trustees of all or any part of the Collateral, in each case with such rights, powers, duties and obligations consistent with this
Trust Indenture as may be provided in such supplemental indenture or other instruments as the Mortgagee or a Majority in Interest of Note Holders may deem necessary or advisable, or (2) to clarify, add to or subtract from the rights, powers,
duties and obligations theretofore granted any such additional or separate trustee, subject in each case to the remaining provisions of this Section 9.02. If the Owner shall not have taken any action requested of it under this
Section 9.02(a) that is permitted or required by its terms within 15 days after the receipt of a written request from the Mortgagee so to do, or if an Event of Default shall have occurred and be continuing, the Mortgagee may act under the
foregoing provisions of this Section 9.02(a) without the concurrence of the Owner, and the Owner hereby irrevocably appoints (which appointment is coupled with an interest) the Mortgagee, its agent and attorney-in-fact to act for it under the foregoing provisions of this Section 9.02(a) in either of such contingencies. The Mortgagee may, in such capacity, execute, deliver and perform any such
supplemental indenture, or any 

  

			
	TRUST INDENTURE 22-1 (A and B)	  	55

 
such instrument, as may be required for the appointment of any such additional or separate trustee or for the clarification of, addition to or subtraction from the rights, powers, duties or
obligations theretofore granted to any such additional or separate trustee. In case any additional or separate trustee appointed under this Section 9.02(a) shall die, become incapable of acting, resign or be moved, all the assets, property,
rights, powers, trusts, duties and obligations of such additional or separate trustee shall revert to the Mortgagee until a successor additional or separate trustee is appointed as provided in this Section 9.02(a). 

(b) No additional or separate trustee shall be entitled to exercise any of the rights, powers, duties and obligations conferred upon the
Mortgagee in respect of the custody, investment and payment of monies and all monies received by any such additional or separate trustee from or constituting part of the Collateral or otherwise payable under any Operative Agreement to the Mortgagee
shall be promptly paid over by it to the Mortgagee. All other rights, powers, duties and obligations conferred or imposed upon any additional or separate trustee shall be exercised or performed by the Mortgagee and such additional or separate
trustee jointly except to the extent that applicable Law of any jurisdiction in which any particular act is to be performed renders the Mortgagee incompetent or unqualified to perform such act, in which event such rights, powers, duties and
obligations (including the holding of title to all or part of the Collateral in any such jurisdiction) shall be exercised and performed by such additional or separate trustee. No additional or separate trustee shall take any discretionary action
except on the instructions of the Mortgagee or a Majority in Interest of Note Holders. No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, except that the Mortgagee shall be liable for the
consequences of its lack of reasonable care in selecting, and the Mortgagee’s own actions in acting with, any additional or separate trustee. Each additional or separate trustee appointed pursuant to this Section 9.02 shall be subject to,
and shall have the benefit of Articles V through IX and Article XI hereof insofar as they apply to the Mortgagee. The powers of any additional or separate trustee appointed pursuant to this Section 9.02 shall not in any case exceed those of the
Mortgagee hereunder. 
 (c) If at any time the Mortgagee shall deem it no longer necessary or in order to conform to any such Law or take
any such action or shall be advised by such counsel that it is no longer so necessary or desirable in the interest of the Note Holders, or in the event that the Mortgagee shall have been requested to do so in writing by a Majority in Interest of
Note Holders, the Mortgagee and, upon the written request of the Mortgagee, the Owner, shall execute and deliver an indenture supplemental hereto and all other instruments and agreements necessary or proper to remove any additional or separate
trustee. The Mortgagee may act on behalf of the Owner under this Section 9.02(c) when and to the extent it could so act under Section 9.02(a) hereof.

limits of liability, shall operate in all respects as if a separate policy had been issued covering each party insured thereunder; 
 (ix)
shall provide that none of the Additional Insureds shall be liable for any insurance premium; and 
 (x) shall contain a 50/50% Clause per
Lloyd’s Aviation Underwriters’ Association Standard Policy Form AVS 103 or US market equivalent. 
  

	E.	 Reports and Certificates; Other Information 

On or prior to the Closing Date and on or prior to each renewal date of the insurance policies required hereunder, Owner(or Permitted Lessee)
will furnish or cause to be furnished to Mortgagee insurance certificates describing in reasonable detail the insurance maintained by Owner (or Permitted Lessee) hereunder and a report, signed by Owner’s (or Permitted Lessee’s) regularly
retained independent insurance broker (the “Insurance Broker”), stating the opinion of such Insurance Broker that (a) all premiums in connection with such insurance then due have been paid and (b) such insurance complies with the
terms of this Annex B, except that such opinion shall not be required with respect to war risk insurance or indemnity provided by the U.S. Government. To the extent such agreement is reasonably obtainable Owner (or Permitted Lessee) will also cause
the Insurance Broker to agree to advise Mortgagee in writing of any default in the payment of any premium and of any other act or omission on the part of Owner (or Permitted Lessee) of which it has knowledge and which might invalidate or render
unenforceable, in whole or in part, any insurance on the Aircraft or Engines required hereunder or cause the cancellation or termination of such insurance, and to advise Mortgagee in writing at least thirty (30) days (seven (7) days in the
case of war-risk and allied perils coverage and ten (10) days in the case of nonpayment of premium, or such shorter period as may be available in the international insurance market, as the case may be)
prior to the cancellation, lapse or material adverse change of any insurance maintained pursuant to this Annex B. 
  

	F.	 Right to Pay Premiums 

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

	G.	 Deductibles; Self-insurance 

Owner (or Permitted Lessee) may self-insure by way of deductible, premium adjustment or franchise provisions or otherwise (including, with
respect to insurance maintained pursuant to Section B, insuring for a maximum amount which is less than the Debt Balance) in the insurance covering the risks required to be insured against pursuant to Section 4.06 and this Annex B
under a program applicable to all aircraft in Owner’s (or Permitted Lessee’s) fleet, but in no case shall the aggregate amount of self-insurance in regard to Section 4.06 and this Annex B exceed during any policy year, with
respect to all of the aircraft in Owner’s (or Permitted Lessee’s) fleet (including, without limitation, the Aircraft), the lesser of (a) 100% of the largest replacement value of any single aircraft in Owner’s fleet and (b) 1-1/2% of the average aggregate insurable value (during the preceding policy year) of all aircraft (including, without limitation, the Aircraft) on which Owner carries insurance, unless an insurance broker
of national standing shall certify that the standard among all other major U.S. airlines is a higher level of self-insurance, in which case Owner may self-insure to such higher level. In addition, Owner (and any Permitted Lessee) may self-insure to
the extent of any applicable deductible per aircraft that does not exceed industry standards for major U.S. airlines.
