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 Indenture Trustee, 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.

acquittance for any and all monies and claims for monies (in each case including insurance and requisition proceeds) due and to become due under or arising out of the Indenture Agreements, and all other property which now or hereafter constitutes
part of the Collateral, to endorse any checks or other instruments or orders in connection therewith and to file any claims or to take any action or to institute any proceedings which the Indenture Trustee may deem to be necessary or advisable in
the premises; provided that no action of the Indenture Trustee pursuant to this paragraph shall increase the obligations or liabilities of the Owner to any Person beyond those obligations and liabilities specifically set forth in this Trust
Indenture and in the other Operative Agreements and the Indenture Trustee shall not exercise any such rights except upon the occurrence and during the continuance of an Event of Default hereunder. 

The Owner agrees that at any time and from time to time, upon the written request of the Indenture Trustee, the Owner will promptly and
duly execute and deliver or cause to be duly executed and delivered any and all such further instruments and documents (including without limitation UCC continuation statements) as the Indenture Trustee may reasonably deem necessary to perfect,

 US AIRWAYS, INC., a Delaware corporation (“Owner”), hereby promises to pay to
            , or the registered assignee thereof, the principal sum of $             (the “Original Amount”), together
with interest on the amount of the Original Amount remaining unpaid from time to time (calculated on the basis of a year of 360 days comprised of twelve 30-day months) from the date hereof until paid in full at a rate per annum equal to the Debt
Rate. The Original Amount of this Equipment Note shall be due and payable in installments on the dates set forth in Schedule I hereto equal to the corresponding percentage of the Original Amount of this Equipment Note set forth in Schedule I hereto.
Accrued but unpaid interest shall be due and payable in semi-annual installments commencing on [            ] 1, 201[    ] and thereafter on June 3 and
December 3 of each year, to and including [            ]. Notwithstanding the foregoing, the final payment made on this Equipment Note shall be in an amount sufficient to discharge in
full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, this Equipment Note. Notwithstanding anything to the contrary contained herein, if any date on which a payment under this Equipment Note becomes
due and payable is not a Business Day, then such payment shall not be made on such scheduled date but shall be made on the next succeeding Business Day and if such payment is made on such next succeeding Business Day, no interest shall accrue on the
amount of such payment during such extension. 
 For purposes hereof, the term “Trust Indenture” means the Trust
Indenture and Security Agreement [            ] dated as of [                 ],
20[    ], between the Owner, Wilmington Trust, National Association as securities intermediary and Wilmington Trust Company (the “Indenture Trustee”), as the same may be amended or supplemented from time to time. All
other capitalized terms used in this Equipment Note and not defined herein shall have the respective meanings assigned in the Trust Indenture. 
 This Equipment Note shall bear interest, payable on demand, at the Payment Due Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any overdue Original Amount, any
overdue Make-Whole Amount, if any, and (to the extent 

  
 5 

 
permitted by applicable Law) any overdue interest and any other amounts payable hereunder which are overdue, in each case for the period the same is overdue. Amounts shall be overdue if not paid
when due (whether at stated maturity, by acceleration or otherwise). 
 There shall be maintained an Equipment Note Register for
the purpose of registering transfers and exchanges of Equipment Notes at the Corporate Trust Office of the Indenture Trustee or at the office of any successor in the manner provided in Section 2.06 of the Trust Indenture. 

The Original Amount and interest and other amounts due hereunder shall be payable in Dollars in immediately available funds at the
Corporate Trust Office of the Indenture Trustee, or as otherwise provided in the Trust Indenture. Each such payment shall be made on the date such payment is due and without any presentment or surrender of this Equipment Note, except that in the
case of any final payment with respect to this Equipment Note, the Equipment Note shall be surrendered promptly thereafter to the Indenture Trustee for cancellation. 
 The holder hereof, by its acceptance of this Equipment Note, agrees that, except as provided in the Trust Indenture, each payment of the Original Amount, Make-Whole Amount, if any, and interest received
by it hereunder shall be applied, first, to the payment of Make-Whole Amount, if any, and any other amount (other than as covered by any of the following clauses) due hereunder or under the Trust Indenture, second, to the payment of
accrued interest on this Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, or, to the extent permitted by Law, any overdue interest and other amounts hereunder) to the date of such
payment, third, to the payment of the Original Amount of this Equipment Note then due, and fourth, the balance, if any, remaining thereafter, to the payment of installments of the Original Amount of this Equipment Note remaining unpaid
in the inverse order of their maturity. 
 This Equipment Note is one of the Equipment Notes referred to in the Trust Indenture
which have been or are to be issued by the Owner pursuant to the terms of the Trust Indenture. The Collateral is held by the Indenture Trustee as security, in part, for the Equipment Notes. The provisions of this Equipment Note are subject to the
Trust Indenture and the Related Indentures. Reference is hereby made to the Trust Indenture and the Related Indentures for a complete statement of the rights and obligations of the holder of, and the nature and extent of the security for, this
Equipment Note (including as a “Related Equipment Note” under each of the Related Indentures) and the rights and obligations of the holders of, and the nature and extent of the security for, any other Equipment Notes executed and delivered
under the Trust Indenture, as well as for a statement of the terms and conditions of the Trust created by the Trust Indenture, to all of which terms and conditions in the Trust Indenture each holder hereof agrees by its acceptance of this Equipment
Note. 
 As provided in the Trust Indenture and subject to certain limitations therein set forth, this Equipment Note is
exchangeable for a like aggregate Original Amount of Equipment Notes of different authorized denominations, as requested by the holder surrendering the same. 
 Prior to due presentment for registration of transfer of this Equipment Note, the Owner and the Indenture Trustee shall treat the person in whose name this Equipment Note is registered as the owner hereof
for all purposes, whether or not this Equipment Note be overdue, and neither the Owner nor the Indenture Trustee shall be affected by notice to the contrary.

the Trust Indenture but not otherwise. In addition, this Equipment Note may be accelerated as provided in Section 5.02 of the Trust Indenture. 
 This Equipment Note is subject to certain restrictions set forth in Sections 4.1(a)(i) and 4.1(a)(iii) of the Intercreditor Agreement, as further specified in Section 2.06 of the Trust Indenture, to
all of which terms and conditions in the Intercreditor Agreement each holder hereof agrees by its acceptance of this Equipment Note. 
 [The indebtedness evidenced by this Equipment Note is, to the extent and in the manner provided in the Trust Indenture, subordinate and subject in right of payment to the prior payment in full of the
Secured Obligations (as defined in the Trust Indenture) in respect of [Series A Equipment Notes and Related Series A Equipment Notes]1 [Series A Equipment Notes, Series B Equipment Notes, Related Series A Equipment Notes and Related Series B Equipment

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, the Owner shall have the option to issue Series C Equipment Notes at any time after the Closing Date, subject to the terms of
Section 4(a)(v) of the Note Purchase Agreement and Section 9.1(d) of the Intercreditor Agreement. If the Owner so elects to issue the Series C Equipment Notes, Series C Equipment Notes shall be issued in a single separate series, shall be
dated the date of original issuance thereof and shall have such maturity, principal amount and interest rate 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 2.10(b) and new Series C Equipment Notes may be issued pursuant to the provisions of Section 2.10(c). 
 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 [            ] 1, 201[    ], and on each June 3 and December 3 thereafter until maturity. The
Original Amount of each Equipment Note shall be payable on the dates and in the installments equal to the corresponding percentage of the Original Amount as set forth in Schedule I hereto (as amended, in the case of Series C, at the time of original
issuance of Series C) 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. 
 The Owner agrees to
pay to the Indenture Trustee for distribution in accordance with Section 3.04 hereof: (a)(i) to the extent not payable (whether or not in fact paid) under Section 6(a) of the Note Purchase Agreement, an amount equal to the fees payable to
the 

  
 10 

 
Liquidity Provider under Section 2.03 of each Liquidity Facility and the related Fee Letter (as defined in the Intercreditor Agreement) multiplied by a fraction the numerator of which shall
be the then outstanding aggregate principal amount of the Series A Equipment Notes and Series B Equipment Notes and the denominator of which shall be the then outstanding aggregate principal amount of all “Series A Equipment Notes” and
“Series B Equipment Notes” (each as defined in the Note Purchase Agreement); (ii) (x) the amount equal to interest on any Downgrade Advance (other than any Applied Downgrade Advance) payable under Section 3.07 of each
Liquidity Facility minus Investment Earnings from such Downgrade Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iii) (x) the amount equal to interest on any Non-Extension Advance (other than any Applied
Non-Extension Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Non-Extension Advance multiplied by (y) the fraction specified in the foregoing clause (i); (iv) (x) the amount
equal to interest on any Special Termination Advance (other than any Applied Special Termination Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Special Termination Advance multiplied by
(y) the fraction specified in the foregoing clause (i); (v) if any payment default shall have occurred and be continuing with respect to interest on any “Series A Equipment Notes” or “Series B Equipment Notes” (each as
defined in the Note Purchase Agreement), (x) the excess, if any, of (1) an amount equal to interest on any Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied Special Termination Advance payable under
Section 3.07 of each Liquidity Facility over (2) the sum of Investment Earnings from any Final Advance plus any amount of interest at the Payment Due Rate actually payable (whether or not in fact paid) by the Owner on the overdue scheduled
interest on the “Equipment Notes” (as defined in the Note Purchase Agreement) in respect of which such Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied Special Termination Advance was made by the
Liquidity Provider multiplied by (y) a fraction the numerator of which shall be the then aggregate overdue amounts of interest on the Series A Equipment Notes and Series B Equipment Notes (other than interest becoming due and payable solely as
a result of acceleration of any such Equipment Notes) and the denominator of which shall be the then aggregate overdue amounts of interest on all “Series A Equipment Notes” and “Series B Equipment Notes” (each as defined in the
Note Purchase Agreement) (other than interest becoming due and payable solely as a result of acceleration of any such “Equipment Notes”); and (vi) any other amounts owed to the Liquidity Provider by the Subordination Agent as borrower
under each Liquidity Facility other than amounts due as repayment of advances thereunder or as interest on such advances, except to the extent payable pursuant to clause (ii), (iii), (iv) or (v) above, multiplied by the fraction specified
in the foregoing clause (i), (b) without duplication of any amounts paid or payable pursuant to the provisions hereof, Owner’s pro rata share of all compensation and reimbursement of expenses, disbursements and advances payable by the
Owner under the Pass Through Trust Agreements, (c) without duplication of any amounts paid or payable pursuant to the provisions hereof, 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 and (d) in the
event the Owner requests any amendment to any Operative Agreement or Pass Through Agreement, the Owner’s pro rata share of all reasonable fees and expenses (including, without limitation, fees and disbursements of counsel) of the Escrow Agents
and the Paying Agents in connection therewith 

  
 11 

 
payable by the Pass Through Trustees under the Escrow Agreements. 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). For purposes of this
paragraph, (i) the terms “Applied Downgrade Advance”, “Applied Non-Extension Advance”, “Applied Special Termination Advance”, “Downgrade Advance”, “Final Advance”, “Investment
Earnings”, “Non-Extension Advance”, “Special Termination Advance” and “Unpaid Advance” shall have the meanings specified in each Liquidity Facility and (ii) the term “Cash Collateral Account” shall
have the meaning specified in the Intercreditor Agreement. 
 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
Indenture Trustee for authentication upon original issue and such Equipment Notes shall thereupon be authenticated and delivered by the Indenture Trustee 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 Indenture Trustee 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 Series C, at the time of original issuance of Series C). 
 SECTION 2.03. 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 p.m., New York time, on the due date of payment to the Indenture
Trustee 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 Indenture Trustee 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 Indenture Trustee 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 

  
 12 

 
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 Indenture Trustee 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 Indenture Trustee, 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 Indenture Trustee shall be entitled to any interest earned on such funds until such payment is made. Any payment made
hereunder shall be made without any presentment or surrender of any Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to the Indenture Trustee for cancellation
promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Indenture Trustee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which
it is practicable for the Indenture Trustee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 p.m., 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee consistent with this Section 2.03. 

(b) The Indenture Trustee, 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 Indenture Trustee agrees to act as such withholding agent and, in connection therewith, whenever any present or future
United States taxes or similar charges are required to be withheld with respect to any amounts payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and
on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner)
appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time. 
 If a Note Holder which is a Non-U.S. Person has furnished to the Indenture Trustee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8BEN, W-8EXP or W-8IMY (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

  
 13 

 
of such payment), or in any of the three preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of such form prior to the date of such payment (and
the Indenture Trustee has no reason to believe that any information set forth in such form is inaccurate), the Indenture Trustee 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 Indenture Trustee 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) 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 any of the three preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Indenture Trustee
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 Indenture Trustee 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 Indenture Trustee 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 an applicable income tax convention, the Code or the regulations thereunder
or the administrative interpretation of any of the foregoing 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 Indenture
Trustee 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. 
 SECTION
2.04. 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; 
 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 2.09, 2.10 and 2.11 hereof).

  
 14 

 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 maturity. 
 SECTION 2.05. 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 Indenture Trustee 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 2.06. Registration Transfer and Exchange of
Equipment Notes 
 The Indenture Trustee shall keep a register (the “Equipment Note Register”) in which the
Indenture Trustee shall provide for the registration of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note
Register shall be kept at the Corporate Trust Office of the Indenture Trustee. The Indenture Trustee is hereby appointed “Equipment Note Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein
provided. A holder of any Equipment Note intending to exchange such Equipment Note shall surrender such Equipment Note to the Indenture Trustee 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 Indenture
Trustee 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 Indenture Trustee at the Corporate Trust Office. Whenever any Equipment Notes are
so surrendered for exchange, the Owner shall execute, and the Indenture Trustee shall authenticate and deliver, the Equipment Notes which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of
transfer or exchange of Equipment Notes (whether under this Section 2.06 or under Section 2.07 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 Indenture Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in 

  
 15 

 
form satisfactory to the Indenture Trustee duly executed by the Note Holder or such holder’s attorney duly authorized in writing, and the Indenture Trustee shall require evidence
satisfactory to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of any applicable state. The Indenture Trustee 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 Indenture Trustee and such change is reflected on the Equipment Note Register. The Indenture Trustee 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 Indenture Trustee 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 2.06, the Indenture Trustee and the 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 2.07. 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 Indenture Trustee 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 Indenture Trustee and a
photocopy thereof shall be furnished to the Owner. If the Equipment Note being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the Owner and the Indenture Trustee such security or indemnity as may be
required by them to save the Owner and the Indenture Trustee harmless and evidence satisfactory to the Owner and the Indenture Trustee 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 

  
 16 

 
form reasonably satisfactory the 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 2.07, the Indenture Trustee and the 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 2.08. 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 Indenture Trustee, as Equipment Note Registrar, may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of
Equipment Notes. 
 (b) The Indenture Trustee shall cancel all Equipment Notes surrendered for replacement, redemption,
transfer, exchange, payment or cancellation and shall destroy the canceled Equipment Notes. 
 SECTION 2.09. 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 than Related Secured Obligations) owed or then due and payable to the Note Holders but without Make-Whole Amount. 
 SECTION 2.10. Optional Redemptions of Equipment Notes

at the interest rate in effect for such Equipment Note as of such redemption date. 
 SECTION 2.12. Subordination

SECTION 3.07. Securities Account 
 In furtherance of the provisions of Section 3.03 of this Trust Indenture, WTNA agrees to act as an Eligible Institution under this Trust Indenture in accordance with the provisions of this Trust
Indenture (in such capacity, the “Securities Intermediary”). WTNA waives any claim or lien against any Eligible Account it may have, by operation of law or otherwise, for any amount owed to it by the Owner. The Securities Intermediary
hereby agrees that, notwithstanding anything to the contrary in this Trust Indenture, (i) any amounts to be held by the Securities Intermediary pursuant to paragraph (iv) of clause “Third” of Section 3.03 and any investment
earnings thereon or other Cash Equivalents will be credited to an Eligible Account (the “Securities Account”) for which it is a “securities intermediary” (as defined in Section 8-102(a)(14) of the NY UCC) and the Indenture
Trustee is the “entitlement holder” (as defined in Section 8-102(a)(7) of the NY UCC) of the “securities entitlement” (as defined in Section 8-102(a)(17) of the NY UCC) with respect to each “financial asset”

Account, (iii) all items of property (whether cash, investment property, Cash Equivalents, other investments, securities, instruments or other property) credited to the Securities Account will be treated as a “financial asset” under
Article 8 of the NY UCC, (iv) its “securities intermediary’s jurisdiction” (as defined in Section 8-110(e) of the NY UCC) with respect to the Securities Account is the State of New York, and (v) all securities,
instruments and other property in order or registered from and credited to the Securities Account shall be payable to or to the order of, or registered in the name of, the Securities Intermediary or shall be indorsed to the Securities Intermediary
or in blank, and in no case whatsoever shall any financial asset credited to the Securities Account be registered in the name of the Owner, payable 

  
 25 

 
to or to the order of the Owner or specially indorsed to the Owner except to the extent the foregoing have been specially endorsed by the Owner to the Securities Intermediary or in blank. The
Securities Intermediary agrees that it will hold (and will indicate clearly in its books and records that it holds) the Indenture Trustee’s “securities entitlement” to the “financial assets” credited to the Securities
Account in trust for the benefit of the Note Holders and each of the Indenture Indemnitees as set forth in this Trust Indenture. The Owner and the Securities Intermediary acknowledge that, by reason of the Indenture Trustee being the
“entitlement holder” in respect of the Securities Account as provided above, the Indenture Trustee 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.

to the Owner’s account specified in Schedule 1 to the Participation Agreement.

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.

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, medical emergency or other circumstances beyond the reasonable control of the Owner (or any Permitted Lessee), so long as the Owner (or any Permitted Lessee) diligently and in good faith proceeds to remove the
Aircraft from such area. The Owner shall also have the right to operate the Aircraft without having on board the original registration certificate or airworthiness certificate in the event that either or both such certificates disappear from the
Aircraft, but only to the extent permitted by Exemption No. 5318 of the FAA Regulations or other similar exemption. 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 of any Government Entity having jurisdiction over the Aircraft that is 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 the 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 the 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 the Indenture Trustee or impair the Indenture Trustee’s security interest or International Interest in the Aircraft, Airframe or any Engine. Owner shall
not be in default under or required to take any action set forth in the preceding sentence if it is not possible for Owner to comply with the laws of a jurisdiction other than the United States (or other jurisdiction in which the Aircraft is
registered) because of a conflict with the Laws of the United States (or other jurisdiction in which the Aircraft is registered). 
 (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 Owner’s FAA approved maintenance program or while registered in another
jurisdiction, under the applicable maintenance standards required by the Aviation Authority in such jurisdiction 

  
 30 

 
(provided, that in any case, if operated under the maintenance program of an Aviation Authority other the FAA, the Aircraft, Airframe and each Engine shall be maintained according to
standards substantially equivalent to those required by the Aviation Authority of any of Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland
or the United Kingdom) so as to (A) keep the Aircraft, the Airframe and each Engine in as good operating condition as on the Closing Date, ordinary wear and tear excepted, (B) keep the Aircraft in such operating condition as may be
necessary to enable the applicable airworthiness certification of such Aircraft to be maintained under the regulations of the FAA or other Aviation Authority then having jurisdiction over the operation of the Aircraft, except (w) during
temporary periods of storage in accordance with applicable regulations, (x) maintenance, testing and modification permitted hereunder, (y) during periods when the FAA or such other Aviation Authority has revoked or suspended the
airworthiness certificates for Similar Aircraft or (z) with respect to minor or nonrecurring violations with respect to which corrective measures are taken upon discovery thereof and except to the extent the Owner or Permitted Lessee is
promptly 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 the Indenture Trustee therein or any material risk of criminal liability or material civil penalty against the Indenture Trustee; and (ii) except during periods when a Permitted Lease is
in effect, the same standards as the Owner uses with respect to similar aircraft of similar size in its fleet operated by the 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 the Owner’s obligations under the
preceding clause (i)). The Owner further agrees that the Aircraft, Airframe and Engines will be maintained, used, serviced, repaired, overhauled or inspected in compliance with each applicable airworthiness certificate, license and registration
relating to the Aircraft, Airframe or any Engine issued by the FAA (or other applicable Aviation Authority). 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, the Owner
may, by written notice to the Indenture Trustee, request to change the country of registration of the Aircraft. Any such change in registration shall be effected only in compliance with, and subject to all of the conditions set forth in,
Section 6.4.5 of the Participation Agreement. Unless the Trust Indenture has been discharged, the Owner shall also cause the Trust Indenture to be duly recorded and at all times maintained of record as a first-priority perfected mortgage
(subject to Permitted Liens) on the Aircraft, the Airframe and each of the Engines (except to the extent such perfection or priority cannot be maintained solely as a result of the failure by the Indenture Trustee to execute and deliver any necessary
documents). Unless the Lien of this Indenture has been discharged, the Owner shall cause the International Interest granted under this Indenture in favor of the Indenture Trustee in each Airframe and Engine to be registered on the International
Registry as an International Interest on such Airframe and Engine, subject to the Indenture Trustee providing its consent to the International Registry with respect thereto, and shall cause the sale to the Owner of the Airframe and each Engine at
the Closing to be registered on the International Registry. 

  
 31 

 (f) Markings. If permitted by applicable Law, on or reasonably promptly after the
Closing Date, the Owner will cause to be affixed to, and maintained in, the cockpit of the Airframe and on each Engine, in each case, in a clearly visible location, a placard of a reasonable size and shape bearing the legend: “Subject to a
security interest in favor of Wilmington Trust Company, not in its individual capacity but solely as Indenture Trustee.” 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, the Owner shall promptly replace it with a placard complying with the requirements of this Section. 
 SECTION 4.03. Inspection 
 (a) At all reasonable times upon at least 15
Business Days prior written notice to Owner, so long as the Aircraft is subject to the Lien of this Trust Indenture, the Indenture Trustee and its authorized representatives (the “Inspecting Parties”) may (not more than once every twelve
(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 the 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 the like or other components of the Aircraft, and no such inspection shall interfere with the Owner’s or any Permitted Lessee’s maintenance and operation of the Aircraft, Airframe and Engines. Any inspection shall be
subject to the Owner’s safety and security rules applicable to the location of the Aircraft. 
 (c) With respect to such
rights of inspection, the Indenture Trustee 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 of Engines 
 (a) Replacement of Parts. Except as otherwise provided herein, so long as the
Airframe or Engine is subject to the Lien of this Trust Indenture, the 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, except as otherwise provided in 

  
 32 

 
paragraph (d) of this Section 4.04 or if the Airframe or Engine to which a Part relates has suffered an Event of Loss. In addition, the 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 the Owner, except as otherwise provided herein, at its own cost and expense, will, or will cause a Permitted Lessee at its own cost and expense to,
replace such Parts as promptly as practicable. All replacement parts shall be free and clear of all Liens, except for Permitted Liens and pooling arrangements to the extent permitted by Section 4.04(c) below (and except in the case of
replacement property temporarily installed on an emergency basis) and shall be in good operating condition and have a value and utility not less than the value and utility of the Parts replaced (assuming such replaced Parts were in the condition
required hereunder). 
 (b) Parts. Except as otherwise provided herein, any Part at any time removed from the Airframe
or any Engine shall remain subject to the Lien of this Trust Indenture, no matter where located, until such time as such Part shall be replaced by a part that has been incorporated or installed in or attached to such Airframe or any Engine and that
meets the requirements for replacement parts specified above. Immediately upon any replacement part becoming incorporated or installed in or attached to such Airframe or any Engine as provided in Section 4.04(a), without further act,
(i) the replaced Part shall thereupon be free and clear of all rights of the Indenture Trustee 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. Upon request of Owner, the Indenture Trustee shall,
at Owner’s expense, execute and deliver to Owner such documents as may be reasonably required to evidence the release of any replaced Part from the Lien of the Indenture. 

(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 the 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). 

  
 33 

 (d) Alterations, Modifications and Additions. The Owner shall, or shall cause a
Permitted Lessee to, make (or cause to be made) alterations and modifications in and additions to the Aircraft, Airframe and each Engine as may be required to be made from time to time to meet the applicable standards of the FAA or other Aviation
Authority having jurisdiction over the operation of the Aircraft, to the extent made mandatory in respect of the Aircraft (a “Mandatory Modification”); except for (i) immaterial and non-recurring violations with respect to which
corrective measures are being taken promptly by Owner or a Permitted Lessee and (ii) any law, rule, regulation or order the validity or application of which is being contested in good faith by the Owner or any Permitted Lessee in any reasonable
manner which does not materially adversely affect the Indenture Trustee’s interest in the Aircraft, does not impair the Indenture Trustee’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 the Indenture Trustee therein or any material risk of material civil penalty or any material risk of criminal liability being imposed on the Indenture Trustee or the holder of any
Equipment Note. In addition, the Owner, at its own expense, may, or may permit a Permitted Lessee at its own cost and expense to, from time to time make or cause to be made such alterations and modifications in and additions to the Airframe or any
Engine (each an “Optional Modification”) as the Owner or such Permitted Lessee may deem desirable in the proper conduct of its business including, without limitation, removal of Parts which the 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. For the avoidance of doubt, Owner may make alterations in the passenger configuration of the Aircraft and such alterations shall not constitute an Optional
Modification. 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 

  
 34 

 
provided in this Section 4.04(d), title thereto shall, without further act, be free and clear of all rights of the Indenture Trustee and such Part shall no longer be deemed a Part hereunder.
Removable Parts may be leased from or financed by third parties other than the Indenture Trustee. Notwithstanding any other provision of this Indenture, Owner may, at any time, install or permit to be installed in the Aircraft Passenger
Convenience Equipment owned by Owner or any Permitted Lessee or by third parties and leased or otherwise furnished to Owner in the ordinary course of business (including pursuant to a conditional sale contract, a licence or otherwise), and Owner may
remove (and not replace) or permit to be removed (and not replaced) the same, and Indenture Trustee shall not acquire a Lien thereon by virtue of such installation or otherwise, and the rights of the owners therein shall not constitute a default
under this Trust Indenture, it being acknowledged and agreed, however, that in no event shall the installation of any such Passenger Convenience Equipment impair or otherwise affect the rights and remedies of the Indenture Trustee hereunder and
under applicable law. 
 (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, the Owner shall promptly (and in any event within fifteen (15) days after such occurrence) give the Indenture Trustee written notice of such Event of
Loss. The Owner shall have the right at its option at any time, on at least five (5) Business Days’ prior notice to the Indenture Trustee, 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 one hundred and twenty (120) 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 Indenture Trustee and the Lien of this Trust Indenture and shall no longer be deemed
an Engine hereunder and (ii) such Replacement Engine shall become subject to this Trust Indenture and be deemed part of the Aircraft for all purposes hereof to the same extent as the replaced Engine. Such Replacement Engine shall be an engine
manufactured by Engine Manufacturer that is the same model as the Engine to be replaced thereby, or an improved model, and that is suitable for installation and use on the Airframe, and that has a value, utility and remaining useful life (without
regard to hours and cycles remaining until overhaul) at least equal to the Engine to be replaced thereby (assuming that such Engine had been maintained in accordance with this Trust Indenture). The Owner’s right to make a replacement hereunder
shall be subject to the fulfillment (which may be simultaneous with such replacement) of the following conditions precedent at the Owner’s sole cost and expense, and the Indenture Trustee 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 Indenture Trustee: 
 (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; 

  
 35 

 (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 Indenture Trustee); 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 Indenture Trustee to protect the security interests of the
Indenture Trustee in the Replacement Engine; 
 (ii) the Owner shall cause to be delivered to the Indenture Trustee 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 the Indenture Trustee shall reasonably request; 
 (iii) promptly after the filing of the Trust Indenture
Supplement, the Owner shall have caused to be furnished to the Indenture Trustee an opinion of the Owner’s aviation law counsel reasonably satisfactory to the Indenture Trustee addressed to the Indenture Trustee 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 the Owner shall have caused to be effected) with the International Registry of the sale to the 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 
 (iv) the
Owner shall have furnished to the Indenture Trustee a certificate of a qualified aircraft engineer (who may be an employee of the Owner) or an independent appraiser certifying that such Replacement Engine has a value and utility and remaining useful
life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine so replaced (assuming that such Engine had been maintained in accordance with this Trust Indenture). 

Upon satisfaction of all conditions to such substitution, (x) the Indenture Trustee 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 Indenture Trustee 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). 

  
 36 

 SECTION 4.05. Loss, Destruction or Requisition 

(a) Event of Loss With Respect to the Airframe. Upon the occurrence of an Event of Loss with respect to the Airframe, the Owner
shall promptly (and in any event within fifteen (15) days after such occurrence) give the Indenture Trustee written notice of such Event of Loss. The Owner shall, within forty-five (45) days after such occurrence, give the Indenture
Trustee written notice of the 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 the
Owner shall not have given the Indenture Trustee such notice of such election within the above specified time period, the Owner shall be deemed to have elected to make payment in respect of such Event of Loss as provided under
Section 4.05(a)(ii)): 
 (i) if the Owner elects to replace the Airframe, the Owner shall, subject to the satisfaction of
the conditions contained in Section 4.05(c), as promptly as possible and in any event within one hundred and twenty (120) days after the occurrence of such Event of Loss, cause to be subjected to the Lien of this Trust Indenture, in
replacement of the Airframe with respect to which the Event of Loss occurred, a Replacement Airframe and, if any Engine shall have been installed on the Airframe when it suffered the Event of Loss, a Replacement Engine therefor, such Replacement
Airframe and Replacement Engines to be free and clear of all Liens except Permitted Liens and to have a value, utility and remaining useful life (without regard to hours or cycles remaining until the next regular maintenance check) at least equal to
the Airframe or Engine, as the case may be, to be replaced thereby (assuming that such Airframe or Engine had been maintained in accordance with this Trust Indenture); provided that if the Owner shall not perform its obligation to
effect such replacement under this clause (i) during the 120-day period of time provided herein, it shall pay the amounts required to be paid pursuant to and within the time frame specified in clause (ii) below; or 

(ii) if the Owner elects to make a payment in respect of such Event of Loss of the Airframe, the Owner shall make a
payment to the Indenture Trustee for purposes of redeeming Equipment Notes in accordance with Section 2.09 hereof on a date on or before the Business Day next following the earlier of (x) the one hundred and twentieth (120)th day following
the date of the occurrence of such Event of Loss, and (y) the fourth (4th) 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 the 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 Indenture Trustee shall, at the cost and expense of the Owner, release from the Lien of this Trust
Indenture the Airframe and the Engines, by executing and delivering to the Owner all documents and instruments as the Owner may reasonably request to evidence such release. 
 (b) Effect of Replacement. Should the Owner have provided a Replacement Airframe and Replacement Engines, if any, as provided for in Section 4.05(a)(i), (i) the Lien of this Trust
Indenture shall continue with respect to such Replacement Airframe and Replacement Engines, if any, as though no Event of Loss had occurred; (ii) the Indenture Trustee shall, at the cost and expense of the Owner, release from the Lien of this
Trust Indenture the replaced Airframe and Engines, if any, by executing and delivering to the Owner such documents and instruments as the Owner may reasonably request to evidence such release; and (iii) in the case of a replacement upon an
Event of Loss, the Indenture Trustee shall assign to the 

  
 37 

 
Owner all claims the Indenture Trustee may have against any other Person arising from the Event of Loss and the Owner shall receive all insurance proceeds (other than those reserved to others
under Section 4.06(b)) and proceeds from any award in respect of condemnation, confiscation, seizure or requisition, including any investment interest thereon, to the extent not previously applied to the purchase price of the Replacement
Airframe and Replacement Engines, if any, as provided in Section 4.05(d). 
 (c) Conditions to Airframe and Engine
Replacement. The Owner’s right to substitute a Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(a)(i) shall be subject to the fulfillment, at the Owner’s sole cost and expense, in addition to the
conditions contained in such Section 4.05(a)(i), of the following conditions precedent: 
 (i) on the date when the
Replacement Airframe and Replacement Engines, if any, is subjected to the Lien of this Trust Indenture (such date being referred to in this Section 4.05 as the “Replacement Closing Date”), an executed counterpart of each of the
following documents (or, in the case of the FAA Bill of Sale and full warranty bill of sale referred to below, a photocopy thereof) shall have been delivered to the Indenture Trustee: 

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

and 
 (D) UCC financing statements (or any similar statements or other documents required to be filed or
delivered pursuant to the laws of the jurisdiction in which the Replacement Airframe and Replacement Engines, if any, may be registered in accordance with Section 4.02(e)) as are deemed necessary or desirable by counsel for the Indenture
Trustee to protect the security interests of the Indenture Trustee in the Replacement Airframe and Replacement Engines, if any; 
 (ii) the Replacement Airframe and Replacement Engines, if any, shall be of the same model as the Airframe or Engines, as the case may be, or an improved model of such aircraft or engines of the
manufacturer thereof, shall have a value and utility 

  
 38 

 
(without regard to hours or cycles remaining until the next regular maintenance check) at least equal to, and be in as good operating condition and repair as, the Airframe and any Engines
replaced (assuming such Airframe and Engines had been maintained in accordance with this Trust Indenture); 
 (iii) the
Indenture Trustee (acting directly or by authorization to its special counsel) shall have received satisfactory evidence as to the compliance with Section 4.06 with respect to the Replacement Airframe and Replacement Engines, if any;

Indenture Supplement in favor of the Indenture Trustee with respect to such Replacement Airframe and Replacement Engine(s), if any, each to be registered on the International Registry as a sale or an International Interest, respectively; 

(v) the Indenture Trustee at the expense of the Owner, shall have received (acting directly or by authorization to its special counsel)
(A) an opinion of counsel, addressed to the Indenture Trustee, to the effect that the Replacement Airframe and Replacement Engine, if any, has or have duly been made subject to the Lien of this Trust Indenture, and the Indenture Trustee will be
entitled to the benefits of Section 1110 with respect to the Replacement Airframe, provided that such opinion with respect to Section 1110 need not be delivered to the extent that immediately prior to such replacement the benefits of
Section 1110 were not, solely by reason of a change in law or court interpretation thereof, available to the Indenture Trustee; 
 (vi) promptly after the filing of the Trust Indenture Supplement, the Owner shall cause to be furnished to the Indenture Trustee an opinion of the Owner’s aviation law counsel reasonably satisfactory
to and addressed to the Indenture Trustee as to the due registration of any such Replacement Airframe and the due filing for recordation of each Trust Indenture Supplement with respect to such Replacement Airframe or Replacement Engine under the Act
or such other applicable law of the jurisdiction other than the United States in which the Replacement Airframe is to be registered in accordance with Section 4.02(e), as the case may be, and the registration (which the Owner shall have caused
to be effected) 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 

  
 39 

 (vii) the Owner shall have furnished to the Indenture Trustee a certificate of a qualified
aircraft engineer (who may be an employee of the Owner) or an independent appraiser certifying that the Replacement Airframe and Replacement Engines, if any, have a value and utility and remaining useful life (without regard to hours and cycles
remaining until overhaul) at least equal to the Airframe and any Engines so replaced (assuming that such Airframe and Engines had been maintained in accordance with this Trust Indenture). 

(d) Non-Insurance Payments Received on Account of an Event of Loss. Any amounts, other than insurance proceeds in respect of
damage or loss not constituting an Event of Loss (the application of which is provided for in Annex B), received at any time by the Indenture Trustee or the Owner from any Government Entity or any other Person in respect of any Event of Loss will be
applied as follows: 
 (i) If such amounts are received with respect to the Airframe, and any Engine installed
thereon at the time of such Event of Loss, upon compliance by the Owner with the applicable terms of Section 4.05(c) with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to, or retained by, the
Owner; 
 (ii) If such amounts are received with respect to an Engine (other than an Engine installed on the
Airframe at the time such Airframe suffers an Event of Loss), upon compliance by the Owner with the applicable terms of Section 4.04(e) with respect to the Event of Loss for which such amounts are received, such amounts shall be paid over to,
or retained by, the Owner; 
 (iii) If such amounts are received, in whole or in part, with respect to the
Airframe, and the Owner makes, has made or is deemed to have made the election set forth in Section 4.05(a)(ii), such amounts shall be applied as follows: 
 first, if the sum described in Section 4.05(a)(ii) has not then been paid in full by the Owner, such amounts shall be paid to the Indenture Trustee to the extent necessary to pay in full such
sum; and 
 second, the remainder, if any, shall be paid to the Owner. 

(e) Requisition for Use. In the event of a requisition for use by any Government Entity of the Airframe and the Engines, if any,
or engines installed on such Airframe while such Airframe is subject to the Lien of this Trust Indenture, the Owner shall promptly notify the Indenture Trustee 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 Indenture Trustee or the Owner or Permitted Lessee from such Government Entity with respect to such requisition of use shall
be paid over to, or 

  
 40 

 
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 Indenture Trustee 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 Indenture Trustee 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. The 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) Indenture Trustee 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 the Owner pursuant to this Section 4.06 and Annex B. 
 (c) Indemnification by
Government in Lieu of Insurance. The Indenture Trustee 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 the Indenture Trustee, 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 the 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. 

(d) Application of Insurance Proceeds. As between the Owner and the Indenture Trustee, 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 the 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 the 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 

  
 41 

 
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,
the Owner. 
 SECTION 4.07. Merger of Owner 
 (a) In General. The 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 the Indenture Trustee a duly authorized, legal, valid, binding and enforceable agreement,
reasonably satisfactory in form and substance to the Indenture Trustee, 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 the 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 and, irrespective of the registry of the
Aircraft, such person makes such registrations with the International Registry, in any case, as shall be necessary to evidence such consolidation or merger; and 
 (iv) immediately after giving effect to such consolidation or merger no Event of Default shall have occurred and be continuing. 
 (b) Effect of Merger. Upon any such consolidation or merger of the Owner with or into, or the conveyance, transfer or lease by the 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, the 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 the Owner under this Trust
Indenture.

from the Indenture Trustee, unless such failure is capable of being corrected and the Owner shall be diligently proceeding to correct such failure, in which case there shall be no Event of Default unless and until such failure shall continue
unremedied for a period of two hundred and seventy (270) days after receipt of such notice; 
 (iv) any representation or
warranty made by the Owner herein, in the Participation Agreement or in any other Operative Agreement to which Owner is a party (a) shall prove to have been untrue or inaccurate in any material respect as of the date made, (b) such untrue
or inaccurate representation or warranty is material at the time in question, (c) and the same shall remain uncured (to the extent of the adverse impact of such incorrectness on the interest of the Indenture Trustee) for a period in excess of

 (v) the
Owner shall consent to the appointment of or taking possession by a receiver, trustee or liquidator of itself or of a substantial part of its property, or the Owner shall admit in writing its inability to pay its debts generally as they come due or

(vii) a petition against the Owner in a proceeding under any bankruptcy laws or other insolvency laws (as in effect at such time) is

 (viii) the occurrence of a Related Indenture Event of Default. 
 provided, however, that, notwithstanding anything to the contrary contained in this Section 5.01, any failure of Owner to perform or observe any covenant, condition, agreement or any
error in a representation or warranty shall not constitute an Event of Default if such failure or error is caused solely by reason of any event that constitutes an Event of Loss so long as Owner is continuing to comply with all of the terms of
Section 4.04(e) and Section 4.05 hereof. 
 SECTION 5.02. Remedies 

(a) If an Event of Default shall have occurred and be continuing and so long as the same shall continue unremedied, then and in every
such case the Indenture Trustee 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 Indenture Trustee shall give the Owner twenty (20) days’ prior written notice of its intention to sell the Aircraft; provided further, that during any period the
Aircraft is subject to the CRAF program and in possession of the U.S. Government or an agency or instrumentality of the United States, the Indenture Trustee shall not, on account of any Event of Default, be entitled to exercise or pursue any of the
powers, rights or remedies described in this Article V in such manner as to limit the Owner’s control (or any Permitted Lessee’s control under any lease) of any Airframe or any Engines installed thereon, unless at least sixty
(60) days (or such lesser period as may then be applicable under the Air Mobility Command program of the U.S. Government) written notice of default hereunder shall have been given by the Indenture Trustee by registered or certified mail to the
Owner (any Permitted Lessee) with a copy addressed to the Contracting Office Representative of the Air Mobility Command of the United States Air Force under any contract with the Owner (or any Permitted Lessee) relating to the Aircraft. Without
limiting any of the foregoing, it is understood and agreed that the Indenture Trustee 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. 

  
 44 

 (b) If an Event of Default shall have occurred and be continuing, then and in every such
case the Indenture Trustee may (and shall, upon receipt of a written demand therefor from a Majority in Interest of Note Holders), at any time, by delivery of written notice or notices to the Owner, declare all the Equipment Notes to be due and
payable, whereupon the unpaid Original Amount of all Equipment Notes then outstanding, together with accrued but unpaid interest thereon (without Make-Whole Amount) and other amounts due thereunder or otherwise payable hereunder, shall immediately
become due and payable without presentment, demand, protest or notice, all of which are hereby waived; provided that if an Event of Default referred to in clause (v), (vi) or (vii) of Section 5.01 hereof shall have occurred, then and
in every such case the unpaid Original Amount then outstanding, together with accrued but unpaid interest (without Make-Whole Amount) and all other amounts due hereunder and under the Equipment Notes shall immediately and without further act become
due and payable without presentment, demand, protest or notice, all of which are hereby waived. 
 This Section 5.02(b),
however, is subject to the condition that, if at any time after the Original Amount of the Equipment Notes shall have become so due and payable, and before any judgment or decree for the payment of the money so due, or any thereof, shall be entered,
all overdue payments of interest upon the Equipment Notes and all other amounts payable hereunder or under the Equipment Notes (except the Original Amount of the Equipment Notes 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 Indenture Trustee, rescind and annul the Indenture Trustee’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 Indenture Trustee will not be authorized or empowered to acquire title to any Collateral or
take any action with respect to any Collateral so acquired by it if such acquisition or action would cause any Trust to fail to qualify as a “grantor trust” for federal income tax purposes. 

  
 45 

 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
Indenture Trustee, the Owner shall promptly execute and deliver to the Indenture Trustee such instruments of title and other documents as the Indenture Trustee may deem necessary or advisable to enable the Indenture Trustee or an agent or
representative designated by the Indenture Trustee, at such time or times and place or places as the Indenture Trustee may specify, to obtain possession of all or any part of the Collateral to which the Indenture Trustee 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 Indenture Trustee, the Indenture Trustee may (i) obtain a judgment conferring on the Indenture Trustee
the right to immediate possession and requiring the Owner to execute and deliver such instruments and documents to the Indenture Trustee, 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 the 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee may determine, and the Indenture Trustee 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 Indenture Trustee under any provision of this Trust Indenture to collect and receive all
cash held by, or required to be deposited with, the Indenture Trustee 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 Indenture Trustee 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
Indenture Trustee 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 Indenture Trustee, and of all persons properly engaged and employed by the
Indenture Trustee with respect hereto. 

  
 46 

 SECTION 5.04. Remedies Cumulative 

Each and every right, power and remedy given to the Indenture Trustee 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 Indenture Trustee, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver
of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by the Indenture Trustee in the exercise of any right, remedy or power or in the pursuance of any remedy shall impair any such right,
power or remedy or be construed to be a waiver of any default on the part of the Owner or to be an acquiescence therein. 

SECTION 5.05. Discontinuance of Proceedings 
 In case the Indenture Trustee 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 Indenture Trustee, then and in every such case the Owner and the Indenture Trustee shall, subject to any determination in such proceedings, be restored to their
former positions and rights hereunder with respect to the Collateral, and all rights, remedies and powers of the Owner or the Indenture Trustee 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 Indenture Trustee shall waive any past Default hereunder and its consequences and upon any such waiver such Default shall cease to
exist and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this 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 Indenture Trustee shall not waive any Default (i) in the payment of the Original Amount, Make-Whole Amount, if any, and interest and other amounts due under any Equipment
Note then outstanding, or (ii) in respect of a covenant or provision hereof which, under Article X hereof, cannot be modified or amended without the consent of each Note Holder. 

SECTION 5.07. Appointment of Receiver 
 If an Event of Default shall have occurred and be continuing, the Indenture Trustee shall, as a matter of right, be entitled to the appointment of a receiver (who may be the Indenture Trustee or any
successor or nominee thereof) for all or any part of the Collateral, whether such receivership be incidental to a proposed sale of the Collateral or the taking of possession thereof or otherwise, and 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 Indenture Trustee with respect to the Collateral. 

  
 47 

 SECTION 5.08. Indenture Trustee Authorized to Execute Bills of Sale, Etc. 

The Owner irrevocably appoints, while an Event of Default has occurred and is continuing, the Indenture Trustee 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 Indenture Trustee or any purchaser, the Owner shall ratify and confirm any such sale, assignment, transfer or delivery, by executing and delivering to
the Indenture Trustee or such purchaser all bills of sale, assignments, releases and other proper instruments to effect such ratification and confirmation as may be designated in any such request. 

SECTION 5.09. Rights of Note Holders to Receive Payment 
 Notwithstanding any other provision of this Trust Indenture, the right of any Note Holder to receive payment of principal of, and premium, if any, and interest on an Equipment Note on or after the
respective due dates expressed in such Equipment Note, or to bring suit for the enforcement of any such payment on or after such respective dates in accordance with the terms hereof, shall not be impaired or affected without the consent of such Note
Holder. 
 ARTICLE VI 
 DUTIES OF THE INDENTURE TRUSTEE 
 SECTION 6.01. Notice of Event of
Default 
 If the Indenture Trustee 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 Indenture Trustee shall give prompt written notice thereof to each Note Holder. Subject to the terms of Sections 5.06, 6.02 and 6.03 hereof, the Indenture Trustee
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 Indenture Trustee shall be instructed in writing by a
Majority in Interest of Note Holders. Subject to the provisions of Section 6.03, if the Indenture Trustee shall not have received instructions as above provided within 20 days after mailing notice of such Event of Default to the Note Holders,
the Indenture Trustee 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 Indenture Trustee 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 

  
 48 

 
of Actual Knowledge on the part of the Indenture Trustee, the Indenture Trustee shall not be deemed to have knowledge of a Default or an Event of Default (except, the failure of the 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 Indenture Trustee 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 Indenture Trustee shall not, except as provided in Section 6.01, approve any such matter as satisfactory to the Indenture
Trustee. 
 The Indenture Trustee 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 Indenture Trustee 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
Indenture Trustee hereunder. 
 SECTION 6.03. Indemnification 

The Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be accepted as reasonable assurance of adequate indemnity). The Indenture Trustee 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 

  
 49 

 
impose a duty on the Indenture Trustee to take any action, if the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee. The Indenture Trustee
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 Indenture Trustee 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 Indenture Trustee pursuant to this Trust Indenture and in accordance with the express terms hereof. 

SECTION 6.06. Investment of Amounts Held by Indenture Trustee 

Any amounts held by the Indenture Trustee or the Securities Intermediary 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 Indenture Trustee or the Securities Intermediary which are not distributed pursuant to the other provisions of Article III hereof shall be invested by the Indenture
Trustee or the Securities Intermediary, as applicable, from time to time in Cash Equivalents as directed by the Owner so long as the Indenture Trustee or the Securities Intermediary, as applicable, may acquire the same using its best efforts. All
Cash Equivalents held by the Indenture Trustee or the Securities Intermediary 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 Indenture Trustee, 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 Indenture Trustee’s and the Securities Intermediary’s reasonable fees and
expenses in making such investment, shall be held and applied by the Indenture Trustee or the Securities Intermediary, as applicable, 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. Neither the Indenture Trustee nor the Securities Intermediary shall be liable for any loss resulting from any investment required to be made by it

  
 50 

 
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 Indenture Trustee or the Securities Intermediary, as applicable, without instructions whenever such sale is necessary to make a distribution required by this Trust Indenture. 

ARTICLE VII 
 THE INDENTURE TRUSTEE 
 SECTION 7.01. Acceptance of Trusts and Duties

 The Indenture Trustee accepts the duties hereby created and applicable to it and agrees to perform the same but only upon

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

Trustee; Appointment of Successor 
 (a) The Indenture Trustee or any successor thereto may resign at any time without
cause by giving at least thirty (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 Indenture Trustee. In addition, a Majority in
Interest of Note Holders may at any time (but only with the consent of the 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 Indenture Trustee
without cause by an instrument in writing delivered to the Owner and the Indenture Trustee, and the Indenture Trustee shall promptly notify each Note Holder thereof in writing, such removal to be effective upon the acceptance of the trusteeship by a
successor Indenture Trustee. In the case of the resignation or removal of the Indenture Trustee, a Majority in Interest of Note Holders may appoint a successor Indenture Trustee 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 the Owner’s reasonable approval. If a successor Indenture Trustee shall not have been appointed within thirty (30) days after such notice of resignation or
removal, the Indenture Trustee, the Owner or any Note Holder may apply to any court of competent jurisdiction to appoint a successor Indenture Trustee to act until such time, if any, as a successor shall have been appointed as above provided. The
successor Indenture Trustee so appointed by such court shall immediately and without further act be superseded by any successor Indenture Trustee appointed as above provided. 
 (b) Any successor Indenture Trustee, however appointed, shall execute and deliver to the Owner and the predecessor Indenture Trustee an instrument accepting such appointment and assuming the obligations
of the Indenture Trustee arising from and after the time of such appointment, and thereupon such successor Indenture Trustee, without further act, shall become vested with all the estates, properties, rights, powers and duties of the predecessor
Indenture Trustee hereunder in the trust hereunder applicable to it with like effect as if originally named the Indenture Trustee herein; but nevertheless upon the written request of such successor Indenture Trustee, such predecessor Indenture
Trustee shall execute and deliver an instrument transferring to such successor Indenture Trustee, upon the trusts herein expressed applicable to it, all the estates, properties, rights and powers of such predecessor Indenture Trustee, and such
predecessor Indenture Trustee shall duly assign, transfer, deliver and pay over to such successor Indenture Trustee all monies or other property then held by such predecessor Indenture Trustee hereunder. 

(c) No successor Indenture Trustee may be appointed in any manner unless it is 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 with (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 Indenture Trustee hereunder upon reasonable or customary terms. 

  
 55 

 (d) Any corporation into which the Indenture Trustee 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 Indenture Trustee shall be a party, or any corporation to which substantially all the corporate trust business of the Indenture
Trustee may be transferred, shall, subject to the terms of paragraph (c) of this Section 9.01, be a successor Indenture Trustee and the Indenture Trustee under this Trust Indenture without further act. 

(e) The Owner consents to any change in the identity of the Indenture Trustee 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 Indenture Trustee 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 Indenture Trustee shall be advised by counsel satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the Indenture Trustee shall so
advise the Owner), or (iii) the Indenture Trustee shall have been requested to do so by a Majority in Interest of Note Holders, then in any such case, the Indenture Trustee and, upon the written request of the Indenture Trustee, 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
Indenture Trustee, either to act jointly with the Indenture Trustee as additional trustee or trustees of all or any part of the Collateral, or to act as separate trustee or trustees of all or any part of the Collateral, in each case with such
rights, powers, duties and obligations consistent with this Trust Indenture as may be provided in such supplemental indenture or other instruments as the Indenture Trustee 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 Indenture Trustee so to do, or if an Event of Default shall have occurred
and be continuing, the Indenture Trustee 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
Indenture Trustee, 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 Indenture Trustee may, in such capacity, execute, deliver and perform any such
supplemental indenture, or any such instrument, as may be required for the appointment of any such additional or separate trustee or for the clarification of, addition to or subtraction from the rights, powers, duties or obligations theretofore
granted to any such additional or separate trustee. In case any additional or separate trustee appointed under this Section 9.02(a) shall die, become incapable of acting, 

  
 56 

 
resign or be moved, all the assets, property, rights, powers, trusts, duties and obligations of such additional or separate trustee shall revert to the Indenture Trustee 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 Indenture Trustee in respect of the custody, investment and payment of monies and all monies received by any such additional or separate trustee from
or constituting part of the Collateral or otherwise payable under any Operative Agreement to the Indenture Trustee shall be promptly paid over by it to the Indenture Trustee. All other rights, powers, duties and obligations conferred or imposed upon
any additional or separate trustee shall be exercised or performed by the Indenture Trustee and such additional or separate trustee jointly except to the extent that applicable Law of any jurisdiction in which any particular act is to be performed
renders the Indenture Trustee incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations (including the holding of title to all or part of the Collateral in any such jurisdiction) shall be exercised
and performed by such additional or separate trustee. No additional or separate trustee shall take any discretionary action except on the instructions of the Indenture Trustee 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 Indenture Trustee shall be liable for the consequences of its lack of reasonable care in selecting, and the Indenture Trustee’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 Indenture Trustee. The powers of any additional or separate trustee appointed pursuant to this Section 9.02 shall not in any case exceed those of the Indenture Trustee hereunder. 

(c) If at any time the Indenture Trustee 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 Indenture Trustee shall have been requested to do so in writing by a Majority in Interest of Note
Holders, the Indenture Trustee and, upon the written request of the Indenture Trustee, 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 Indenture Trustee 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.
