by such Certificateholders in person or by an agent or proxy duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, when
it is expressly required pursuant to this Agreement, to the Company or any Loan Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the
Certificateholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent or proxy shall be sufficient for any purpose of this Agreement and conclusive in favor of the Trustee, the

partnership, on behalf of such corporation, association or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of
the Person executing the same, may also be proved in any other reasonable manner which the Trustee deems sufficient. 
 (c) In determining
whether the Certificateholders of the requisite Fractional Undivided Interests of Certificates of any series Outstanding have given any Direction under this Agreement, Certificates owned by the Company, any related Owner Trustee, any related Owner
Participant or any Affiliate of any such Person shall be disregarded and deemed not to be Outstanding for purposes of any such determination. In determining whether the Trustee shall be protected in relying upon any such Direction, only Certificates
which the Trustee knows to be so owned shall be so disregarded. Notwithstanding the foregoing, (i) if any such Person owns 100% of the Certificates of any series Outstanding, such Certificates shall not be so disregarded, and (ii) if any
amount of Certificates of any series owned by any such Person have been pledged in good faith, such Certificates shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect
to such Certificates and that the pledgee is not the Company, any related Owner Trustee, any related Owner Participant or any Affiliate of any such Person. 

  
 13 








 (d) The Company may, at its option, by delivery of an Officer’s Certificate to the Trustee,
set a record date to determine the Certificateholders in respect of the Certificates of any series entitled to give any Direction. Notwithstanding Section 316(c) of the Trust Indenture Act, such record date shall be the record date specified in
such Officer’s Certificate, which shall be a date not more than 30 days prior to the first solicitation of Certificateholders of the applicable series in connection therewith. If such a record date is fixed, such Direction may be given before
or after such record date, but only the Certificateholders of record of the applicable series at the close of business on such record date shall be deemed to be Certificateholders for the purposes of determining whether Certificateholders of the
requisite proportion of Outstanding Certificates of such series have authorized or agreed or consented to such Direction, and for that purpose the Outstanding Certificates of such series shall be computed as of such record date; provided, however,
that no such Direction by the Certificateholders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Agreement not later than one year after such record date. Nothing in this paragraph
shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by
any Person be deemed cancelled and of no effect). 
 (e) Any Direction by the Holder of any Certificate shall bind the Holder of every
Certificate issued upon the transfer thereof or in exchange therefor or in lieu thereof, whether or not notation of such Direction is made upon such Certificate. 

(f) Except as otherwise provided in Section 1.04(c), Certificates of any series owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without preference, priority or distinction as among all of the Certificates of such series.

so as to result in the receipt of consideration in an amount equal to the aggregate purchase price of the Equipment Notes (and/or, if applicable, any notes issued by a trust or other entity secured by Equipment Notes) contemplated to be purchased by
the Trustee under the related Note Purchase Agreements and, concurrently therewith (unless the Company shall have delivered to the Trustee the Postponement Notice relating to one or more Postponed Notes pursuant to Subsection (b) below), the
Trustee shall purchase, pursuant to the terms and conditions of the Note Purchase Agreements, such Equipment Notes (except Postponed Notes, if any)(or other notes) at a purchase price equal to the amount of such consideration so received. Except as

Postponed Notes shall be invested (a) by the Trustee at the direction and risk of, and for the benefit of, the Responsible Party in Specified Investments or (b) if provided in the Trust Supplement relating to such series of Certificates

forth therein, in debt instruments of the Company, in each case (i) maturing no later than any scheduled Transfer Date relating to such Postponed Notes, or (ii) if no such Transfer Date

amount equal to the interest that would have accrued on such Postponed Notes if such Postponed Notes had been purchased on the later of the Issuance Date or the previous Regular Distribution Date in respect of the Certificates of such series to, but
not including, such Regular Distribution Date. On the first Regular Distribution Date in respect of the Certificates of any series following the purchase of any Postponed Notes by the Trustee, the Responsible Party will pay (in immediately available
funds) to the Trustee an amount equal to the interest that would have accrued on such Postponed Notes if such Postponed Notes had been purchased on the later of the Issuance Date or the previous Regular Distribution Date in respect of the
Certificates of such series to, but not including, the date of the purchase of such Postponed Notes by the Trustee. 
 If, in respect of the
Certificates of any series, the Company notifies the Trustee prior to the Cut-off Date that any Postponed Notes will not be issued on or prior to the Cut-off Date for any reason, on the next Special Distribution Date for such Certificates occurring
not less than 15 days following the date of such notice, (i) the Responsible Party shall pay (in immediately available funds) to the Trustee for deposit in the related Special Payments Account, an amount equal to the interest that would have
accrued on the Postponed Notes designated in such notice from the later of the Issuance Date or the previous Regular Distribution Date in respect of the Certificates of such series to, but not including, such Special Distribution Date and
(ii) the Trustee shall transfer an amount equal to that amount of Escrowed Funds that would have been used to purchase the Postponed Notes designated in such notice and the amount paid by the Responsible Party pursuant to the immediately
preceding clause (i) to the related Special Payments Account for distribution as a Special Payment in accordance with the provisions hereof. 

  
 18 








 If, on such Cut-off Date, an amount equal to less than all of the Escrowed Funds (other than
Escrowed Funds referred to in the immediately preceding paragraph) has been used to purchase Postponed Notes, on the next Special Distribution Date occurring not less than 15 days following such Cut-off Date (i) the Responsible Party shall pay
to the Trustee for deposit in such Special Payments Account, in immediately available funds, an amount equal to the interest that would have accrued on such Postponed Notes contemplated to be purchased with such unused Escrowed Funds (other than
Escrowed Funds referred to in the immediately preceding paragraph) but not so purchased from the later of the Issuance Date or the previous Regular Distribution Date in respect of the Certificates of such series to, but not including, such Special
Distribution Date and (ii) the Trustee shall transfer such unused Escrowed Funds and the amount paid by the Responsible Party pursuant to the immediately preceding clause (i) to such Special Payments Account for distribution as a Special
Payment in accordance with the provisions hereof.

of a Trust Supplement creating a Trust and establishing a series of Certificates, shall acknowledge its acceptance of all right, title and interest in and to the Trust Property to be acquired pursuant to Section 2.02 hereof and the related Note
Purchase Agreements and shall declare that the Trustee holds and will hold such right, title and interest for the benefit of all then present and future Certificateholders of such series, upon the trusts herein and in such Trust Supplement set

Trust shall be constituted solely for the purpose of making the investment in the Equipment Notes provided for in the related Trust Supplement, and, except as set forth herein or in such related Trust Supplement, the Trustee shall not be authorized
or empowered to acquire any other investments or engage in any other activities. Except to the extent otherwise provided in the applicable Trust Supplement, the Trustee shall not be authorized or empowered to do anything that would cause such Trust
to fail to qualify as a “grantor trust” for federal income tax purposes (including as subject to this restriction, acquiring any Aircraft (as defined in the related Indentures) by bidding such Equipment Notes or otherwise, or taking any
action with respect to any such Aircraft once acquired). 
 ARTICLE III. 

THE CERTIFICATES 
 Section 3.01
Form, Denomination and Execution of Certificates. Except to the extent otherwise specified in the applicable Trust Supplement, the Certificates of each series shall be issued in fully registered form without coupons and shall be substantially
in the form specified in such Trust Supplement, with such omissions, variations and insertions as are permitted by this Agreement, and may have such letters, numbers or other marks of identification and such


  
 19 








 
legends or endorsements placed thereon as may be required to comply with any applicable laws, rules, regulations or the rules of any securities exchange on which such Certificates may be listed
or to conform to any usage in respect thereof, or as may, consistently herewith, be determined by the Trustee or the officers executing such Certificates, as evidenced by the Trustee’s or such officers’ execution of the Certificates. 

Except as provided in Section 3.05, the definitive Certificates of such series shall be typed, printed, lithographed or engraved or
produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which the Certificates may be listed, all as determined by the officers executing such Certificates, as
evidenced by their execution of such Certificates. 
 Except as otherwise provided in the related Trust Supplement, the Certificates of each
series shall be issued in minimum denominations of $1,000 or integral multiples thereof except that one Certificate of such series may be issued in a different denomination. The Certificates of such series shall be executed on behalf of the Trustee
by manual or facsimile signature of a Responsible Officer of the Trustee. Certificates of any series bearing the manual or facsimile signature of an individual who was, at the time when such signature was affixed, authorized to sign on behalf of the
Trustee shall be valid and binding obligations of the Trustee, notwithstanding that such individual has ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such office at the date of such
Certificates. 
 Section 3.02 Authentication of Certificates. (a) Except to the extent otherwise specified in the applicable
Trust Supplement, on the Issuance Date, the Trustee shall duly execute, authenticate and deliver Certificates of each series in authorized denominations equaling in the aggregate the aggregate face amount of the Equipment Notes that may be purchased
by the Trustee pursuant to the related Note Purchase Agreements, and evidencing the entire ownership of the related Trust. Thereafter, the Trustee shall duly execute, authenticate and deliver the Certificates of such series as herein provided. 

(b) No Certificate of any series shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on
such Certificate a certificate of authentication substantially in the form set forth in the Trust Supplement relating to such series of Certificates executed by the Trustee by manual signature, and such certificate of authentication upon any
Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates of any series shall be dated the date of their authentication. 

Section 3.03 Temporary Certificates. Until definitive Certificates are ready for delivery, the Trustee shall execute, authenticate and
deliver temporary Certificates of each series. Temporary Certificates of each series shall be substantially in the form of definitive Certificates of such series but may have insertions, substitutions, omissions and other variations determined to be
appropriate by the officers executing the temporary Certificates of such series, as evidenced by their execution of such temporary Certificates. If temporary Certificates of any series are issued, the Trustee will cause definitive Certificates of
such series to be prepared without unreasonable delay. After the preparation of definitive Certificates of such series, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of such temporary


  
 20 








 
Certificates at the Corporate Trust Office or the office or agency of the Trustee designated for such purpose pursuant to Section 7.12, without charge to the Certificateholder. Upon
surrender for cancellation of any one or more temporary Certificates, the Trustee shall execute, authenticate and deliver in exchange therefor a like face amount of definitive Certificates of like series, in authorized denominations and of a like
Fractional Undivided Interest. Until so exchanged, such temporary Certificates shall be entitled to the same benefits under this Agreement as definitive Certificates of such series. 

Section 3.04 Transfer and Exchange. The Trustee shall cause to be kept at the office or agency to be maintained by it in accordance
with the provisions of Section 7.12 a register (the “Register”) for each series of Certificates in which, subject to such reasonable regulations as it may prescribe, the Trustee shall provide for the registration of Certificates of
such series and of transfers and exchanges of such Certificates as herein provided. The Trustee shall initially be the registrar (the “Registrar”) for the purpose of registering such Certificates of each series and transfers and exchanges
of such Certificates as herein provided. 
 All Certificates issued upon any registration of transfer or exchange of Certificates of any
series shall be valid obligations of the applicable Trust, evidencing the same interest therein, and entitled to the same benefits under this Agreement, as the Certificates of such series surrendered upon such registration of transfer or exchange.

 Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office or such other office or agency, the Trustee
shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of like series, in authorized denominations of a like aggregate Fractional Undivided Interest. 

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of like series, in authorized denominations and of
a like aggregate Fractional Undivided Interest, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate and deliver the
Certificates that the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Trustee and the Registrar duly executed by the Certificateholder thereof or its attorney duly authorized in writing. 

Except to the extent otherwise provided in the applicable Trust Supplement, no service charge shall be made to a Certificateholder for any
registration of transfer or exchange of Certificates, but the Trustee shall require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates. All Certificates
surrendered for registration of transfer or exchange shall be cancelled and subsequently destroyed by the Trustee. 
 Section 3.05
Book-Entry and Definitive Certificates. (a) The Certificates of any series may be issued at the option of the Company in the form of one or more typewritten Certificates representing the Book-Entry Certificates of such series, to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the Company. In such case, the 

  
 21 








 
Certificates of such series delivered to The Depository Trust Company shall initially be registered on the Register in the name of Cede & Co., the nominee of the initial Clearing Agency,
and no Certificate Owner will receive a definitive certificate representing such Certificate Owner’s interest in the Certificates of such series, except as provided in Subsection (d) below. As to the Certificates of any such series (other
than the one Certificate or such series issued in a denomination of other than an even multiple of $1,000), unless and until definitive, fully registered Certificates (the “Definitive Certificates”) have been issued pursuant to Subsection
(d) below: 
 (1) the provisions of this Section 3.05 shall be in full force and effect; 

(2) the Company, the Paying Agent, the Registrar and the Trustee may deal with the Clearing Agency for all purposes (including
the making of distributions on the Certificates); 
 (3) to the extent that the provisions of this Section 3.05 conflict
with any other provisions of this Agreement (other than the provisions of any Trust Supplement expressly amending this Section 3.05 as permitted by this Basic Agreement), the provisions of this Section 3.05 shall control; 

(4) the rights of Certificate Owners shall be exercised only through the Clearing Agency and shall be limited to those
established by law and agreements between such Certificate Owners and the Clearing Agency Participants; and until Definitive Certificates are issued pursuant to Subsection (d) below, the Clearing Agency will make book-entry transfers among the
Clearing Agency Participants and receive and transmit distributions of principal, interest and premium, if any, on the Certificates to such Clearing Agency Participants; 

(5) such Certificates of such series may be transferred in whole, but not in part, and in the manner provided in
Section 3.04, by the Clearing Agency holding such Certificates to a nominee of such Clearing Agency, or by such Clearing Agency to a successor Clearing Agency that has been selected or approved by the Company or to a nominee of such successor
Clearing Agency; and 
 (6) whenever this Agreement requires or permits actions to be taken based upon instructions or
directions of Certificateholders of such series holding Certificates of such series evidencing a specified percentage of the Fractional Undivided Interests in the related Trust, the Clearing Agency shall be deemed to represent such percentage only
to the extent that it has received instructions to such effect from Clearing Agency Participants owning or representing, respectively, such required percentage of the beneficial interest in Certificates of such series and has delivered such
instructions to the Trustee. None of the Company, the Parent or the Trustee or any agent of any of them shall have any obligation to determine whether the Clearing Agency has in fact received any such instructions. 

(b) Whenever notice or other communication to the Certificateholders of a series is required under this Agreement, unless and until Definitive
Certificates shall have been issued pursuant to Subsection (d) below, the Trustee shall give all such notices and communications specified herein to be given to Certificateholders of such series to the Clearing Agency. 

  
 22 








 (c) Except as otherwise provided in the related Trust Supplement, the Trustee shall enter into
the applicable Letter of Representations with respect to each series of Certificates and fulfill its responsibilities thereunder. 
 (d) If
with respect to the Certificates of any series (i) the Company advises the Trustee in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities and the Trustee or the Company is unable to locate a
qualified successor, (ii) the Company, at its option, advises the Trustee in writing that it elects to terminate the book-entry system through the Clearing Agency or (iii) after the occurrence of an Event of Default, Certificate Owners of
Book-Entry Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust, by Act of such Certificate Owners delivered to the Company and the Trustee, advise the Company,
the Trustee and the Clearing Agency through the Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency Participants is no longer in the best interests of the Certificate Owners of such
series, then the Trustee shall notify all Certificate Owners of such series, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive Certificates. Upon surrender to the Trustee of all the Certificates
of such series held by the Clearing Agency, accompanied by registration instructions from the Clearing Agency Participants for registration of Definitive Certificates in the names of Certificate Owners of such series, the Trustee shall issue and
deliver the Definitive Certificates of such series in accordance with the instructions of the Clearing Agency. Neither the Company, the Registrar, the Paying Agent nor the Trustee shall be liable for any delay in delivery of such instructions and
may conclusively rely on, and shall be protected in relying on, such registration instructions. Upon the issuance of Definitive Certificates of such series, the Trustee shall recognize the Persons in whose names the Definitive Certificates are
registered in the Register as Certificateholders hereunder. Neither the Company nor the Trustee shall be liable if the Trustee or the Company is unable to locate a qualified successor Clearing Agency. 

(e) The provisions of this Section 3.05 may be made inapplicable to any series or may be amended with respect to any series in the
related Trust Supplement. 
 Section 3.06 Mutilated, Destroyed, Lost or Stolen Certificates. If (i) any mutilated Certificate is
surrendered to the Registrar, or the Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Registrar and the Trustee such security, indemnity or bond as may be
required by them to save each of them and the Company harmless, then, in the absence of notice to the Registrar or the Trustee that such destroyed, lost or stolen Certificate has been acquired by a protected purchaser (within the meaning of Article
8 of the Uniform Commercial Code in effect in any applicable jurisdiction), and provided that the requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Trustee shall execute,
authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or Certificates of like series, in authorized denominations and of like Fractional Undivided Interest and bearing a
number not contemporaneously outstanding. 

  
 23 








 In connection with the issuance of any new Certificate under this Section 3.06, the Trustee
shall require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and the Registrar) connected therewith. 

Any duplicate Certificate issued pursuant to this Section 3.06 shall constitute conclusive evidence of the appropriate Fractional
Undivided Interest in the related Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. 

The provisions of this Section 3.06 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Certificates. 
 Section 3.07 Persons Deemed Owners. Prior to due
presentment of a Certificate for registration of transfer, the Company, the Trustee, the Registrar and any Paying Agent shall deem and treat the Person in whose name any Certificate is registered (as of the day of determination) on the Register as
the owner of such Certificate and the Certificateholder for the purpose of receiving distributions pursuant to Article IV and for all other purposes whatsoever, and none of the Company, the Trustee, the Registrar or any Paying Agent shall be
affected by any notice to the contrary. All payments or distributions made to any such Person shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable on any such Certificate.

 Unless otherwise provided with respect to any Certificates pursuant to Section 2.01(b), the Company, the Parent, any other obligor
upon any Certificates and any Affiliate of any thereof may acquire, tender for, purchase, own, hold, become the pledgee of and otherwise deal with any Certificates. 

Section 3.08 Cancellation. All Certificates surrendered for payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar for cancellation and shall promptly be cancelled by it. No Certificates shall be authenticated in lieu of or in exchange for any Certificates cancelled as provided in this
Section 3.08, except as expressly permitted by this Agreement. All cancelled Certificates held by the Registrar shall be destroyed and a certification of their destruction delivered to the Trustee. 

Section 3.09 Limitation of Liability for Payments. All payments and distributions made to Certificateholders of any series in respect
of the Certificates of such series shall be made only from the Trust Property of the related Trust and only to the extent that the Trustee shall have sufficient income or proceeds from such Trust Property to make such payments in accordance with the
terms of Article IV of this Agreement. The Certificates do not represent indebtedness of the related Trusts, and references herein or in any Trust Supplement to interest accruing on any Certificates are intended for purposes of computation only.
Each Certificateholder, by its acceptance of a Certificate, agrees that it will look solely to the income and proceeds from the Trust Property of the related Trust for any payment or distribution due to such Certificateholder pursuant to the terms
of this Agreement and that it will not have any recourse to the Company, the Trustee, the Loan Trustees, any Owner Trustee or any Owner Participant except as otherwise expressly provided in this Agreement, in any Note Document or in any related
Intercreditor Agreement. 

  
 24 








 The Company is a party to this Agreement solely for purposes of meeting the requirements of the
Trust Indenture Act, and therefore shall not have any right, obligation or liability hereunder, or under the terms of any Trust Supplement or any Certificates (except as otherwise expressly provided herein or therein). 

Section 3.10 CUSIP Numbers. The Certificates may include “CUSIP” numbers (if then generally in use), and if so, the Trustee
may use the CUSIP numbers in notices in respect of the Certificates; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Certificates,
that reliance may be placed only on the other identification numbers printed on the Certificates, and any such notice shall not be affected by any defect or omission of such CUSIP numbers.

Subordination Agent to present) to the Loan Trustee to which an Equipment Note relates such Equipment Note on the date of its stated final maturity or, in the case of any Equipment Note which is to be redeemed or purchased in whole pursuant to the
related Indenture, on the applicable redemption or purchase date under such Indenture.

designated by such Clearing Agency (or such nominee). 
 (b) Subject to the provisions of any Intercreditor Agreement, on each Special
Distribution Date with respect to any Special Payment with respect to a series of Certificates or as soon thereafter as the Trustee has confirmed receipt of any Special Payments due on the Equipment Notes held in the related Trust or realized upon
the sale of such Equipment Notes, the Trustee shall distribute out of the applicable Special Payments Account the entire amount of such applicable Special Payment deposited therein pursuant to Section 4.01(b). There shall be so distributed to
each Certificateholder of record of such series on the Record Date with respect to such Special Distribution Date (other than as provided in Section 11.01 concerning the final distribution) by check mailed to such Certificateholder, at the

 (c) The Trustee shall, at the expense of the Company, cause notice of each
Special Payment with respect to a series of Certificates to be mailed to each Certificateholder of such series at his address as it appears in the Register. Subject to the provisions of any Intercreditor Agreement: (i) in the event of
redemption or purchase of Equipment Notes held in the related Trust, such notice shall be mailed not less than 15 days prior to the Special Distribution Date for the Special Payment resulting from such redemption or purchase, which Special
Distribution Date shall be the date of such redemption or purchase; (ii) in the event that the Trustee receives a notice from the Company pursuant to Section 2.02(b) that Postponed Notes will not be purchased by the Trustee, such notice of
Special Payment shall be mailed as soon as practicable after receipt of such notice from the Company and shall state the Special Distribution Date for such Special Payment, which shall occur 15 days after the date of such notice of Special Payment
or (if such 15th day is not practicable) as soon as practicable thereafter; (iii) in the event that any Special Payment is to be made pursuant to the last paragraph of Section 2.02(b), such notice of Special Payment shall be mailed on the

 26 








 
Distribution Date for such Special Payment, which shall occur 15 days after the date of such notice of Special Payment or (if such 15th day is not practicable) as soon as practicable thereafter;
and (iv) in the case of any other Special Payments, such notice of Special Payment shall be mailed as soon as practicable after the Trustee has confirmed that it has received funds for such Special Payment and shall state the Special
Distribution Date for such Special Payment, which shall occur 15 days after the date of such notice of Special Payment or (if such 15th day is not practicable) as soon as practicable thereafter. Notices mailed by the Trustee as provided in the
paragraphs above shall set forth: 
 (i) the Special Distribution Date and the Record Date therefor (except as otherwise
provided in Section 11.01); 
 (ii) the amount of the Special Payment (taking into account any payment to be made by the
Responsible Party pursuant to Section 2.02(b)) for each $1,000 face amount Certificate and the amount thereof constituting principal, premium, if any, and interest; 

(iii) the reason for the Special Payment; and 

(iv) if the Special Distribution Date is the same date as a Regular Distribution Date for the Certificates of such series, the
total amount to be received on such date for each $1,000 face amount Certificate. 
 If the amount of premium, if any, payable upon the
redemption or purchase of an Equipment Note has not been calculated at the time that the Trustee mails notice of a Special Payment, it shall be sufficient if the notice sets forth the other amounts to be distributed and states that any premium
received will also be distributed. 
 If any redemption or purchase of the Equipment Notes held in any Trust is cancelled, the Trustee, as
soon as possible after learning thereof, shall cause notice thereof to be mailed to each Certificateholder of the related series at its address as it appears on the Register. 

Section 4.03 Statements to Certificateholders. (a) On each Regular Distribution Date and Special Distribution Date, the Trustee
will include with each distribution to Certificateholders of the related series a statement, giving effect to the distribution to be made on such Regular Distribution Date or Special Distribution Date, and, except to the extent otherwise provided in
the applicable Trust Supplement, setting forth the following information (per $1,000 aggregate face amount of Certificate as to (i) and (ii) below): 

(i) the amount of such distribution allocable to principal and the amount allocable to premium, if any; 

(ii) the amount of such distribution allocable to interest; and 

(iii) the Pool Balance and the Pool Factor of the related Trust.

Distribution Date and Special Distribution Date, the Trustee will request from the Clearing Agency a securities position listing setting forth 

  
 27 








 
the names of all the Clearing Agency Participants reflected on the Clearing Agency’s books as holding interests in the Certificates on such Record Date. On each Regular Distribution Date and
Special Distribution Date, the applicable Trustee will mail to each such Clearing Agency Participant the statement described above and will make available additional copies as requested by such Clearing Agency Participants for forwarding to holders
of interests in the Certificates. 
 (b) Within a reasonable period of time after the end of each calendar year but not later than the
latest date permitted by law, except to the extent otherwise provided in the applicable Trust Supplement, the Trustee shall furnish to each Person who at any time during such calendar year was a Certificateholder of record a statement containing the
sum of the amounts determined pursuant to clauses (a)(i) and (a)(ii) above with respect to the related Trust for such calendar year or, in the event such Person was a Certificateholder of record during a portion of such calendar year, for the
applicable portion of such year, and such other items as are readily available to the Trustee and which a Certificateholder may reasonably request as necessary for the purpose of such Certificateholder’s preparation of its federal income tax
returns. With respect to Certificates registered in the name of a Clearing Agency or its nominee, such statement and such other items shall be prepared on the basis of information supplied to the Trustee by the Clearing Agency Participants and shall
be delivered by the Trustee to such Clearing Agency Participants to be available for forwarding by such Clearing Agency Participants to the holders of interests in the Certificates. 

Section 4.04 Investment of Special Payment Moneys. Any money received by the Trustee pursuant to Section 4.01(b) representing a
Special Payment which is not distributed on the date received shall, to the extent practicable, be invested by the Trustee in Permitted Investments selected by the Company in telephonic (confirmed in writing) or written instructions to the Trustee
pending distribution of such Special Payment pursuant to Section 4.02. Any investment made pursuant to this Section 4.04 shall be in such Permitted Investments having maturities not later than the date that such moneys are required to be
used to make the payment required under Section 4.02 on the applicable Special Distribution Date and the Trustee shall hold any such Permitted Investments until maturity. Absent receipt of instructions from the Company, such Special Payment
shall remain uninvested by the Trustee pending receipt of investment instructions. The Trustee shall have no liability with respect to any investment made pursuant to this Section 4.04, other than by reason of the willful misconduct or
negligence of the Trustee. All income and earnings from such investments shall be distributed on such Special Distribution Date as part of such Special Payment. 

ARTICLE V. 
 THE COMPANY 

Section 5.01 Maintenance of Corporate Existence. The Company, at its own cost and expense, will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence, rights and franchises, except as otherwise specifically permitted in Section 5.02; provided, however, that the Company shall not be required to preserve any right
or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company. 

  
 28 








 Section 5.02 Consolidation, Merger, Etc. (a) The Company shall not consolidate with or
merge into any other Person under circumstances where the Company is not the surviving Person or convey, transfer or lease substantially all of its assets as an entirety to any Person unless the Person formed by such consolidation or into which the
Company is merged or the Person that acquires by conveyance, transfer or lease substantially all of the assets of the Company as an entirety shall be organized and validly existing under the laws of the United States of America or any state thereof
or the District of Columbia, and such Person shall execute and deliver to the Trustee an agreement in form and substance reasonably satisfactory to the Trustee containing an assumption by such successor Person of the due and punctual performance and
observance of each covenant and condition of this Agreement. 
 (b) Upon any consolidation or merger, or any conveyance, transfer or lease
of substantially all of the assets of the Company as an entirety in accordance with this Section 5.02, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made
shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Agreement with the same effect as if such successor Person had been named as the Company herein. 

(c) The Trustee may receive an Officer’s Certificate and an Opinion of Counsel of the Company as conclusive evidence that any such
consolidation, merger, conveyance, transfer or lease, and any such assumption, complies with the provisions of this Section 5.02. 

ARTICLE VI. 
 DEFAULT 

Section 6.01 Indenture Events of Default and Triggering Events. (a) If in respect of any Trust, any Indenture Event of Default
shall occur and be continuing, then, and in each and every case, so long as such Indenture Event of Default shall be continuing, and subject to the provisions of any Intercreditor Agreement, the Trustee may vote all of the Equipment Notes issued
under the related Indenture and held in such Trust, and, upon the direction of the Certificateholders holding Certificates evidencing Fractional Undivided Interests in such Trust aggregating not less than a majority in interest in such Trust, the
Trustee shall vote not less than a corresponding majority of such Equipment Notes in favor of directing the Loan Trustee under such Indenture to declare the unpaid principal amount of the Equipment Notes then outstanding to which such Indenture
Event of Default relates and accrued interest thereon to be due and payable under, and in accordance with the provisions of, the relevant Indenture. In addition, if an Indenture Event of Default shall have occurred and be continuing under any
Indenture, subject to the provisions of any Intercreditor Agreement, the Trustee may in accordance with the relevant Indenture vote the Equipment Notes held in the Trust to which such Indenture Event of Default relates to direct the Loan Trustee
regarding the exercise of remedies provided in such Indenture. 
 (b) In addition, after an Indenture Event of Default shall have occurred
and be continuing with respect to any Equipment Note, subject to the provisions of any Intercreditor Agreement and the applicable Trust Supplement, the Trustee may in its discretion, and upon the direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests 

  
 29 








 
aggregating not less than a majority in interest in the related Trust shall, by such officer or agent as it may appoint, sell, convey, transfer and deliver such Equipment Note or Equipment Notes,
without recourse to or warranty by the Trustee or any Certificateholder, to any Person. In any such case, the Trustee shall sell, assign, contract to sell or otherwise dispose of and deliver such Equipment Note or Equipment Notes in one or more
parcels at public or private sale or sales, at any location or locations at the option of the Trustee, all upon such terms and conditions as it may reasonably deem advisable and at such prices as it may reasonably deem advisable, for cash. If the
Trustee so decides or is required to sell or otherwise dispose of any Equipment Note pursuant to this Section, the Trustee shall take such of the actions described above as it may reasonably deem most effectual to complete the sale or other
disposition of such Equipment Note. Notwithstanding the foregoing, any action taken by the Trustee under this Section shall not, in the reasonable judgment of the Trustee, be adverse to the best interests of the Certificateholders of such series.

 (c) If an Intercreditor Agreement is applicable, upon the occurrence and during the continuation of any Indenture Event of Default under
any Indenture, the Trustee may, to the extent it is the Controlling Party at such time (as determined pursuant to the related Intercreditor Agreement), direct the exercise of remedies as provided in such related Intercreditor Agreement. 

(d) If an Intercreditor Agreement is applicable, by acceptance of its Certificate, each Certificateholder agrees that at any time after the
occurrence and during the continuation of a Triggering Event, each Certificateholder of Certificates of certain series (each, a “Potential Purchaser” and, collectively, the “Potential Purchasers”) may have certain rights to
purchase the Certificates of one or more other series, all as set forth in the Trust Supplement applicable to the Certificates held by such Potential Purchaser. The purchase price with respect to the Certificates of any series, and the procedure for
such purchase, shall be specified in such Trust Supplement or the applicable Intercreditor Agreement. By acceptance of its Certificate, each Certificateholder (each, a “Selling Certificateholder” and, collectively, the “Selling
Certificateholders”) of a series that is subject to purchase by Potential Purchasers, all as set forth in the Trust Supplement applicable to the Certificates held by the Selling Certificateholders, agrees that, at any time after the occurrence
and during the continuance of a Triggering Event, it will, upon payment of the applicable purchase price by one or more Potential Purchasers (upon such purchase, a “Purchasing Certificateholder”), forthwith sell, assign, transfer and
convey to such Purchasing Certificateholder (without recourse, representation or warranty of any kind except for its own acts) all of the right, title, interest and obligation of such Selling Certificateholder in this Agreement, any related
Intercreditor Agreement, any related Liquidity Facility, the related Note Documents and all Certificates of such series held by such Selling Certificateholder (excluding all right, title and interest under any of the foregoing to the extent such
right, title or interest is with respect to an obligation not then due and payable as respects any action or inaction or state of affairs occurring prior to such sale) and the Purchasing Certificateholder shall assume all of such Selling
Certificateholder’s obligations under this Agreement, any related Intercreditor Agreement, any related Liquidity Facility and the related Note Documents. The Certificates of such series will be deemed to be purchased on the date payment of the
purchase price is made notwithstanding the failure of any Selling Certificateholder to deliver any Certificates of such series and, upon such a purchase, (i) the only rights of the Selling Certificateholders will be to deliver the Certificates
to the Purchasing Certificateholder and receive the purchase price for such Certificates of such series and (ii) if the 

  
 30 








 
Purchasing Certificateholder shall so request, such Selling Certificateholder will comply with all of the provisions of Section 3.04 hereof to enable new Certificates of such series to be
issued to the Purchasing Certificateholder in such denominations as it shall request. All charges and expenses in connection with the issuance of any such new Certificates shall be borne by the Purchasing Certificateholder. 

Section 6.02 Incidents of Sale of Equipment Notes. Upon any sale of all or any part of the Equipment Notes held in the Trust made
either under the power of sale given under this Agreement or otherwise for the enforcement of this Agreement, the following shall be applicable: 

(1) Certificateholders and Trustee May Purchase Equipment Notes. Any Certificateholder, the Trustee in its individual or any
other capacity or any other Person may bid for and purchase any of the Equipment Notes held in the Trust, and upon compliance with the terms of sale, may hold, retain, possess and dispose of such Equipment Notes in their own absolute right without
further accountability. 
 (2) Receipt of Trustee Shall Discharge Purchaser. The receipt of the Trustee making such sale
shall be a sufficient discharge to any purchaser for its purchase money, and, after paying such purchase money and receiving such receipt, such purchaser or its personal representative or assigns shall not be obliged to see to the application of
such purchase money, or be in any way answerable for any loss, misapplication or non-application thereof. 
 (3) Application
of Moneys Received Upon Sale. Any moneys collected by the Trustee upon any sale made either under the power of sale given by this Agreement or otherwise for the enforcement of this Agreement shall be applied as provided in Section 4.02. In the
event that the proceeds of such sale of Equipment Notes are less than the principal amount of the Certificates of such series Outstanding, the Certificateholders shall have no claim for such shortfall against the Company, the Trustee or any other
Person including the related Owner Trustee or related Owner Participant, if any. 
 Section 6.03 Judicial Proceedings Instituted by
Trustee; Trustee May Bring Suit. If there shall be a failure to make payment of the principal of, premium, if any, or interest on any Equipment Note held in the related Trust, or if there shall be any failure to pay Rent (as defined in the
relevant Lease) under any Lease when due and payable, then the Trustee, in its own name and as trustee of an express trust, as holder of such Equipment Notes, to the extent permitted by and in accordance with the terms of any related Intercreditor
Agreement and any related Note Documents (subject to rights of the applicable Owner Trustee or Owner Participant, if any, to cure any such failure to pay principal of, premium, if any, or interest on any Equipment Note or to pay Rent under any Lease
in accordance with the applicable Indenture and to the rights of the Lessee under any applicable Lease), shall be entitled and empowered to institute any suits, actions or proceedings at law, in equity or otherwise, for the collection of the sums so
due and unpaid on such Equipment Notes or under such Lease and may prosecute any such claim or proceeding to judgment or final decree with respect to the whole amount of any such sums so due and unpaid. 

  
 31 








 All rights of action and of asserting claims under this Agreement, or under any of the
Certificates, may be prosecuted and enforced by the Trustee without the possession of any of such Certificates or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys,
shall be for the ratable benefit of the Certificateholders of the related series. 
 In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Agreement, any Trust Supplement, any Intercreditor Agreement or any Liquidity Facility to which the Trustee shall be a party) the Trustee shall be held to represent all the
Certificateholders of the related series, and it shall not be necessary to make any such Certificateholders parties to any such proceedings. 

Section 6.04 Control by Certificateholders. Subject to Section 6.03 and any related Intercreditor Agreement, the
Certificateholders holding Certificates of a series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee with respect to such Trust or pursuant to the terms of such Intercreditor Agreement or any Liquidity Facility to which such Trustee is a party, or exercising any trust or power conferred on the
Trustee under this Agreement or such Intercreditor Agreement or Liquidity Facility, including any right of the Trustee as Controlling Party under such Intercreditor Agreement or as holder of the Equipment Notes held in the related Trust; provided
that: 
 (1) such Direction shall not in the opinion of the Trustee be in conflict with any rule of law or with this
Agreement, and such Direction would not involve the Trustee in personal liability or expense unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the cost, expenses and liabilities which might be
incurred by it in compliance with such Direction; 
 (2) the Trustee shall not determine that the action so directed would be
unjustly prejudicial to the Certificateholders of such series not taking part in such Direction; 
 (3) the Trustee may take
any other action deemed proper by the Trustee which is not inconsistent with such Direction; and 
 (4) if an Indenture Event
of Default under a related Indenture shall have occurred and be continuing, such direction shall not obligate the Trustee to vote more than a corresponding majority of the related Equipment Notes held by the Trust in favor of directing any action by
the related Loan Trustee with respect to such Indenture Event of Default. 
 Section 6.05 Waiver of Past Defaults. Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of a series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the related Trust (i) may on behalf of all of the


  
 32 








 
Certificateholders of such series waive any past default or Event of Default hereunder and its consequences or (ii) if the Trustee is the Controlling Party, may direct the Trustee to
instruct the applicable Loan Trustee to waive any past Indenture default, Indenture Event of Default or, if applicable, the corresponding Lease default, under any related Indenture and its consequences, and thereby annul any Direction given by such
Certificateholders or the Trustee to such Loan Trustee with respect thereto, except a default: 
 (1) in the deposit of any
Scheduled Payment or Special Payment under Section 4.01 or in the distribution of any payment under Section 4.02 on the Certificates of a series; or 

(2) in the payment of the principal of, premium, if any, or interest, if any, on the Equipment Notes held in the related Trust;
or in respect of a covenant or provision hereof which under Article IX hereof cannot be modified or amended without the consent of each Certificateholder holding an Outstanding Certificate of the series affected thereby. 

Upon any such waiver, such default shall cease to exist with respect to the Certificates of such series and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose in respect of such series and any direction given by the Trustee on behalf of the Certificateholders of such series to the relevant Loan Trustee shall be annulled with respect thereto;
but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Upon any such waiver, the Trustee shall vote the Equipment Notes issued under the relevant Indenture to waive the
corresponding Indenture Event of Default (and, if applicable, the corresponding Lease default). 
 Section 6.06 Right of
Certificateholders to Receive Payments Not to Be Impaired. Anything in this Agreement (including Section 6.07) to the contrary notwithstanding, but subject to any related Intercreditor Agreement, the right of any Certificateholder to
receive distributions of payments required pursuant to Section 4.02 hereof on the applicable Certificates when due, or to institute suit for the enforcement of any such payment on or after the applicable Regular Distribution Date or Special
Distribution Date, shall not be impaired or affected without the consent of such Certificateholder. 
 Section 6.07 Certificateholders
May Not Bring Suit Except Under Certain Conditions. A Certificateholder of any series shall not have the right to institute any suit, action or proceeding at law or in equity or otherwise with respect to this Agreement for the appointment of a
receiver or for the enforcement of any other remedy under this Agreement, unless: 
 (1) such Certificateholder previously
shall have given written notice to the Trustee of a continuing Event of Default; 
 (2) Certificateholders holding
Certificates of such series evidencing Fractional Undivided Interests aggregating not less than 25% of the related Trust shall have requested the Trustee in writing to institute such action, suit or proceeding and shall have offered to the Trustee
indemnity as provided in Section 7.03(e); 

  
 33 








 (3) the Trustee shall have refused or neglected to institute any such action,
suit or proceeding for 60 days after receipt of such notice, request and offer of indemnity; and 
 (4) no direction
inconsistent with such written request shall have been given to the Trustee during such 60-day period by Certificateholders holding Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in
interest in the related Trust. 
 Except to the extent provided in any applicable Intercreditor Agreement or in any applicable Trust
Supplement, it is understood and intended that no one or more of the Certificateholders of any series shall have any right in any manner whatsoever hereunder or under the related Trust Supplement or under the Certificates of such series to
(i) surrender, impair, waive, affect, disturb or prejudice any property in the Trust Property of the related Trust, or the lien of any related Indenture on any property subject thereto, or the rights of the Certificateholders of such series or
the holders of the related Equipment Notes, (ii) obtain or seek to obtain priority over or preference with respect to any other such Certificateholder of such series or (iii) enforce any right under this Agreement, except in the manner
provided in this Agreement and for the equal, ratable and common benefit of all the Certificateholders of such series subject to the provisions of this Agreement. 

Section 6.08 Remedies Cumulative. Every right or remedy given hereunder to the Trustee or to any of the Certificateholders of any
series shall not be exclusive of any other right or remedy or remedies, and every such right or remedy shall be cumulative and in addition to every other right or remedy given hereunder or now or hereafter given by statute, law, equity or otherwise.
No delay or omission by the Trustee or of any such Certificateholder 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 applicable Owner Trustee, if any, or the Company, as the case may be, or to be an acquiescence therein. 
 Section 6.09
Discontinuance of Proceedings. If the Trustee or any Certificateholder of any Series institutes any proceeding to enforce any right, power or remedy under the related Trust, and such proceeding is discontinued or abandoned for any reason or
is determined adversely to the Trustee or such Certificateholder, then and in every such case the applicable Owner Trustee, if any, and the applicable Indenture Trustee, the Trustee, the Certificateholders of such Series and the Company shall,
subject to any determination in such proceeding, be restored to their former positions and rights under such Trust with respect to the Trust Property and all rights, remedies and powers of the Trustee and such Certificateholders shall continue as if
no such proceeding had been instituted. 
 Section 6.10 Undertaking for Costs. All parties to this Agreement, and each
Certificateholder by acceptance of a Certificate, shall be deemed to have agreed that, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act or by any
other applicable law; provided, however, that neither this Section 6.10 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company.

 ARTICLE VII. 

THE TRUSTEE 
 Section 7.01
Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default in respect of a Trust, (1) the Trustee undertakes to perform such duties in respect of such Trust as are specifically set forth in this
Agreement, the Intercreditor Agreement and the Note Documents, and no implied covenants or obligations shall be read into such agreements against the Trustee; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement; but in the case of any such certificates or
opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Agreement. 

(b) In case an Event of Default in respect of a Trust has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Agreement in respect of such Trust, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 

(c) No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that: 
 (1) this Subsection (c) shall not be construed to limit
the effect of Subsection (a) of this Section 7.01; and 
 (2) the Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts. 

(d) Whether or not herein expressly so provided, every provision of this Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section 7.01.

As promptly as practicable after, and in any event within 90 days after, the occurrence of any default (as such term is defined below) hereunder known to the Trustee, the Trustee shall transmit by mail to the Company, any related Owner Trustees, any
related Owner Participants, the related Loan Trustees and the Certificateholders holding Certificates of the related series, in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived; provided that, in the case of defaults not relating to the payment of money, the Trustee shall not give such notice until the earlier of the time at which such default
becomes an Event of Default and the expiration of 60 days from the occurrence of such default; and provided, however, that, except in the case of a default in the payment of the 

  
 35 








 
principal, premium, if any, or interest on any Equipment Note, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good faith shall determine that the withholding of such notice is in the interests of the Certificateholders of the related series. For the purpose of this Section 7.02
in respect of any Trust, the term “default” means any event that is, or after notice or lapse of time or both would become, an Event of Default in respect of that Trust or a Triggering Event under any Intercreditor Agreement. 

Section 7.03 Certain Rights of Trustee. Subject to the provisions of Section 315 of the Trust Indenture Act: 

(a) the Trustee may rely and shall be protected in acting or refraining from acting in reliance upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 

(b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Request; 

(c) whenever in the administration of this Agreement or any Intercreditor Agreement the Trustee shall deem it desirable that a matter be
proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer’s Certificate of the
Company, any related Owner Trustee or any related Loan Trustee; 
 (d) the Trustee may consult with counsel and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement or any Intercreditor
Agreement at the Direction of any of the Certificateholders pursuant to this Agreement or any Intercreditor Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the cost, expenses and
liabilities which might be incurred by it in compliance with such Direction; 
 (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document; 

(g) the Trustee may execute any of the trusts or powers under this Agreement or any Intercreditor Agreement or perform any duties under this
Agreement or any Intercreditor Agreement either directly or by or through agents or attorneys, and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it under this
Agreement or any Intercreditor Agreement;

 36 








 
majority in interest in the related Trust relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee, under this Agreement or any Intercreditor Agreement; and 
 (i) the Trustee shall not be required to expend or risk its
own funds in the performance of any of its duties under this Agreement, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk is not
reasonably assured to it. 
 Section 7.04 Not Responsible for Recitals or Issuance of Certificates. The recitals contained herein and
in the Certificates of each series, except the certificates of authentication, shall not be taken as the statements of the Trustee, and the Trustee assumes no responsibility for their correctness. Subject to Section 7.15, the Trustee makes no
representations as to the validity or sufficiency of this Basic Agreement, any Equipment Notes, any Intercreditor Agreement, any Liquidity Facility to which the Trustee may be a party, the Certificates of any series, any Trust Supplement or any Note
Documents, except that the Trustee hereby represents and warrants that this Basic Agreement has been, and each Trust Supplement, each Certificate, each Note Purchase Agreement, each Intercreditor Agreement and any such Liquidity Facility of, or
relating to, each series will be, executed and delivered by one of its officers who is duly authorized to execute and deliver such document on its behalf. 

Section 7.05 May Hold Certificates. The Trustee, any Paying Agent, Registrar or any of their Affiliates or any other agent, in their
respective individual or any other capacity, may become the owner or pledgee of Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture Act, if applicable, may otherwise deal with the Company, the Parent, any Owner Trustees, any
Owner Participants or the Loan Trustees with the same rights it would have if it were not Trustee, Paying Agent, Registrar or such other agent. 

Section 7.06 Money Held in Trust. Money held by the Trustee or the Paying Agent in trust under this Agreement need not be segregated
from other funds except to the extent required herein or by law and neither the Trustee nor the Paying Agent shall have any liability for interest upon any such moneys except as provided for herein or in the applicable Trust Supplement. 

Section 7.07 Compensation and Reimbursement. The Company agrees: 

(1) to pay, or cause to be paid, to the Trustee from time to time such compensation for all services rendered by it hereunder
as the Company and the Trustee may agree in writing from time to time (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); and 

(2) except as otherwise expressly provided herein or in any Trust Supplement, to reimburse, or cause to be reimbursed, the
Trustee upon its request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Basic Agreement, any Trust Supplement, any Intercreditor Agreement or any
Liquidity Facility to which the Trustee may be a party (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to the
Trustee’s negligence, willful misconduct or bad faith or as may be incurred due to the Trustee’s breach of its representations and warranties set forth in Section 7.15; and 

  
 37 








 (3) to indemnify, or cause to be indemnified, the Trustee, solely in its
individual capacity, for, and to hold it harmless against, any loss, liability, tax (other than any tax referred to in the next paragraph or any tax attributable to the Trustee’s compensation for serving as such), cost or expense incurred
without negligence, willful misconduct or bad faith on its part, arising out of or in connection with the acceptance or administration of any Trust, including the costs and expenses of (a) defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties hereunder or under any Trust Supplement or (b) contesting the imposition of any such tax, except in each case for any such loss, liability, tax, cost or expense incurred
by reason of the Trustee’s breach of its representations and warranties set forth in Section 7.15 or in any Trust Supplement or the Trustee’s failure to perform any of its obligations hereunder or under any Trust Supplement. The
Trustee shall notify the Company promptly of any claim or tax for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel with the consent of the Company
and the Company will pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made or any taxes paid, in settlement or otherwise, without its consent. 

The Trustee shall be entitled to reimbursement from, and shall have a lien prior to the Certificates of each series upon, all property and
funds held or collected by the Trustee in its capacity as Trustee with respect to such series or the related Trust for any tax incurred without negligence, bad faith or willful misconduct, on its part, arising out of or in connection with the
acceptance or administration of such Trust (other than any tax attributable to the Trustee’s compensation for serving as such), including any costs and expenses incurred in contesting the imposition of any such tax. The Trustee shall notify the
Company of any claim for any tax for which it may seek reimbursement. If the Trustee reimburses itself from the Trust Property of such Trust for any such tax, it will mail a brief report within 30 days setting forth the amount of such tax and the
circumstances thereof to all Certificateholders of such series as their names and addresses appear in the Register. 
 Section 7.08
Corporate Trustee Required; Eligibility. Each Trust shall at all times have a Trustee which shall be a bank, trust company or other financial institution organized and doing business under the laws of the United States or any state thereof,
shall be eligible to act as a trustee under Section 310(a) of the Trust Indenture Act and shall have a combined capital and surplus of at least $100,000,000 (or a combined capital and surplus in excess of $5,000,000 and the obligations of
which, whether now in existence or hereafter incurred, are fully and unconditionally guaranteed by a corporation organized and doing business under the laws of the United States or any state or territory thereof or the District of Columbia and
having a combined capital and surplus of at least $100,000,000). If such bank, trust company or other financial institution or such corporation publishes reports of conditions at least annually, pursuant to law or to the requirements of federal,
state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section 7.08 the combined capital and surplus of such bank, trust company or other financial institution or such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent report of conditions so published. 

  
 38 








 In case at any time the Trustee shall cease to be eligible in accordance with the provisions of
this Section 7.08 to act as Trustee of any Trust, the Trustee shall resign immediately as Trustee of such Trust in the manner and with the effect specified in Section 7.09. If the Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Agreement. 

Section 7.09 Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of
a successor Trustee of any Trust pursuant to this Article VII shall become effective until the acceptance of appointment by the successor Trustee under Section 7.10. 

(b) The Trustee may resign at any time as Trustee of any or all Trusts by giving prior written notice thereof to the Company, the Authorized
Agents, any related Owner Trustees and the related Loan Trustees. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Company, any related Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

(c) The Trustee may be removed at any time as Trustee of any Trust by Direction of the Certificateholders of the related series holding
Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest in such Trust delivered to the Trustee and to the Company, any related Owner Trustees and the related Loan Trustees. 

(d) If at any time in respect of any Trust: 

(1) the Trustee shall fail to comply with Section 310(b) of the Trust Indenture Act, if applicable, after written request
therefor by the Company or by any Certificateholder who has been a bona fide Certificateholder for at least six months; or 

(2) the Trustee shall cease to be eligible under Section 7.08 and shall fail to resign after written request therefor by
the Company or by any such Certificateholder; or 
 (3) the Trustee shall become incapable of acting or shall be adjudged a
bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;
then, in any such case, (i) the Company may remove the Trustee or (ii) any Certificateholder of the related series who has been a bona fide Certificateholder for at least six months may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee of such Trust. 

(e) If a Responsible Officer of the Trustee shall obtain actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust which
has been or is likely to be 

  
 39 








 
asserted, the Trustee shall promptly notify the Company and shall, within 30 days of such notification, either relocate the administration of the Trust to another jurisdiction as described in the
definition of “Avoidable Tax” or resign as Trustee of such Trust hereunder unless within such 30-day period the Trustee shall have received notice that the Company has agreed to pay such tax. Provided that there is a corporation in a
jurisdiction where there are no Avoidable Taxes that is willing to act as Trustee and is eligible under Section 7.08, the Company shall promptly after any such resignation by such Trustee appoint a successor Trustee of such Trust in a
jurisdiction where there are no Avoidable Taxes. As used herein, an “Avoidable Tax” in respect of such Trust means a state or local tax: (i) upon (w) such Trust, (x) the Trust Property of such Trust,
(y) Certificateholders of such Trust or (z) the Trustee for which the Trustee is entitled to seek reimbursement from the Trust Property of such Trust, and (ii) which would be avoided if the Trust were administered in a different
jurisdiction in the United States or if the Trustee were located in another state, or jurisdiction within a state, within the United States. A tax shall not be an Avoidable Tax in respect of any Trust if the Company or any Owner Trustee shall agree
to pay, and shall pay, such tax. 
 (f) If the Trustee shall resign, be removed or become incapable of acting as Trustee of any Trust or if
a vacancy shall occur in the office of the Trustee of any Trust for any cause, the Company shall promptly appoint a successor Trustee of such Trust. If, within one year after such resignation, removal or incapability, or other occurrence of such
vacancy, a successor Trustee of such Trust shall be appointed by Direction of the Certificateholders of the related series holding Certificates of such series evidencing Fractional Undivided Interests aggregating not less than a majority in interest
in such Trust delivered to the Company, any related Owner Trustees, the related Loan Trustee and the retiring Trustee, then the successor Trustee of such Trust so appointed shall, with the approval of the Company of such appointment, which approval
shall not be unreasonably withheld, forthwith upon its acceptance of such appointment, become the successor Trustee of such Trust and supersede the successor Trustee of such Trust appointed by the Company as provided above. If no successor Trustee
shall have been so appointed by the Company as provided above and accepted appointment in the manner hereinafter provided, the resigning Trustee or any Certificateholder who has been a bona fide Certificateholder of the related series for at least
six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee of such Trust. 

(g) The successor Trustee of a Trust shall give notice of the resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid, to the Certificateholders of the related series as their names and addresses appear in the Register. Each notice shall include the name of such successor Trustee and the
address of its Corporate Trust Office. 
 Section 7.10 Acceptance of Appointment by Successor. Every successor Trustee appointed
hereunder shall execute and deliver to the Company and to the retiring Trustee with respect to any or all Trusts an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee with respect to such Trust or
Trusts shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to such Trust or Trusts; but, on request
of the Company or the successor Trustee, such retiring Trustee 

  
 40 








 
shall execute and deliver an instrument transferring to such successor Trustee all such rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee in respect of such Trusts hereunder (subject nevertheless to its lien, if any, provided for in Section 7.07) and all books and records, or true, correct and complete copies
thereof, held by such retiring Trustee in respect of such Trusts hereunder. Upon request of any such successor Trustee, the Company, the retiring Trustee and such successor Trustee shall execute and deliver any and all instruments containing such
provisions as shall be necessary or desirable to transfer and confirm to, and for more fully and certainly vesting in, such successor Trustee all such rights, powers and trusts. 

If a successor Trustee is appointed with respect to one or more (but not all) Trusts, the Company, the predecessor Trustee and each successor
Trustee with respect to any Trust shall execute and deliver a supplemental agreement hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all of the rights, powers, trusts and duties of the predecessor
Trustee with respect to the Trusts as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Basic Agreement and the applicable Trust
Supplements as shall be necessary to provide for or facilitate the administration of the Trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental agreement shall constitute such Trustees as
co-Trustees of the same Trust and that each such Trustee shall be Trustee of separate Trusts. 
 No institution shall accept its appointment
as a successor Trustee hereunder unless at the time of such acceptance such institution shall be qualified and eligible under this Article VII. 

Section 7.11 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the 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 Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be otherwise qualified and eligible under this Article VII, without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Certificates shall have been executed or authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such
execution or authentication and deliver the Certificates so executed or authenticated with the same effect as if such successor Trustee had itself executed or authenticated such Certificates. 

Section 7.12 Maintenance of Agencies. (a) With respect to each series of Certificates, there shall at all times be maintained an
office or agency in the location set forth in Section 12.04 or at such other location as may be specified in the applicant Trust Supplement where Certificates of such series may be presented or surrendered for registration of transfer or for
exchange, and for payment thereof, and where notices and demands to or upon the Trustee in respect of such Certificates or this Agreement may be served; provided that, if it shall be necessary that the Trustee maintain an office or agency in another
location with respect to the Certificates of any series (e.g., the Certificates of such series shall be represented by Definitive Certificates and shall be listed on a national securities exchange), the Trustee will make all


  
 41 








 
reasonable efforts to establish such an office or agency. Written notice of the location of each such other office or agency and of any change of location thereof shall be given by the Trustee to
the Company, any Owner Trustees, the Loan Trustees (in the case of any Owner Trustee or Loan Trustee, at its address specified in the Note Documents or such other address as may be notified to the Trustee) and the Certificateholders of such series.
In the event that no such office or agency shall be maintained or no such notice of location or of change of location shall be given, presentations and demands may be made and notices may be served at the Corporate Trust Office of the Trustee. 

(b) There shall at all times be a Registrar and a Paying Agent hereunder with respect to the Certificates of each series. Each such Authorized
Agent shall be a bank, trust company or other financial institution organized and doing business under the laws of the United States or any state thereof, with a combined capital and surplus of at least $100,000,000 (or combined capital and surplus
in excess of $5,000,000, the obligations of which are fully and unconditionally guaranteed by a corporation organized and doing business under the laws of the United States or any state or territory thereof or the District of Columbia, with a
combined capital and surplus of at least $100,000,000), and shall be authorized under such laws to exercise corporate trust powers, subject to supervision by federal or state authorities. The Trustee shall initially be the Paying Agent and, as
provided in Section 3.04, Registrar hereunder with respect to the Certificates of each series. Each Registrar other than the Trustee shall furnish to the Trustee, at stated intervals of not more than six months, and at such other times as the
Trustee may request in writing, a copy of the Register maintained by such Registrar. 
 (c) Any corporation, bank or trust company into
which any Authorized Agent may be merged or converted or with which it may be consolidated, or any corporation, bank or trust company resulting from any merger, consolidation or conversion to which any Authorized Agent shall be a party, or any
corporation, bank or trust company succeeding to the corporate trust business of any Authorized Agent, shall be the successor of such Authorized Agent, if such successor is otherwise eligible under this Section 7.12, without the execution or
filing of any paper or any further act on the part of the parties hereto or such Authorized Agent or such successor. 
 (d) Any Authorized
Agent may at any time resign by giving written notice of resignation to the Trustee, the Company, any related Owner Trustees and the related Loan Trustees. The Company may, and at the request of the Trustee shall, at any time terminate the agency of
any Authorized Agent by giving written notice of termination to such Authorized Agent and to the Trustee. Upon the resignation or termination of an Authorized Agent or in case at any time any such Authorized Agent shall cease to be eligible under
this Section 7.12 (when, in either case, no other Authorized Agent performing the functions of such Authorized Agent shall have been appointed), the Company shall promptly appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent which has resigned or whose agency has been terminated or who shall have ceased to be eligible under this Section 7.12. The Company shall give written notice of any
such appointment made by it to the Trustee, any related Owner Trustees and the related Loan Trustees; and in each case the Trustee shall mail notice of such appointment to all Certificateholders of the related series as their names and addresses
appear on the Register for such series. 

  
 42 








 (e) The Company agrees to pay, or cause to be paid, from time to time to each Authorized Agent
such compensation for its services as the Company and the Trustee may agree in writing from time to time and to reimburse it for its reasonable expenses to the extent set forth in Section 7.07(2). 

Section 7.13 Money for Certificate Payments to Be Held in Trust. All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of the Certificateholders entitled to such payment, subject to the provisions of this Section 7.13. Moneys so deposited and held in trust shall constitute a separate
trust fund for the benefit of the Certificateholders with respect to which such money was deposited. 
 The Trustee may at any time, for the
purpose of obtaining the satisfaction and discharge of this Agreement or for any other purpose, direct any Paying Agent to pay to the Trustee all sums held in trust by such Paying Agent, such sums to be held by the Trustee upon the same trusts as
those upon which such sums were held by such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

Section 7.14 Registration of Equipment Notes in Trustee’s Name. Subject to the provisions of any Intercreditor Agreement and
Section 12.03 hereof, the Trustee agrees that all Equipment Notes to be purchased by any Trust, Specified Investments, if any, to be held by the Trustee on behalf of a Trust and Permitted Investments, if any, to be held by the Trustee on behalf
of a Trust shall be issued in the name of the Trustee as trustee for the applicable Trust or its nominee and held by the Trustee in trust for the benefit of the Certificateholders of such series, or, if not so held, the Trustee or its nominee shall
be reflected as the owner of such Equipment Notes, Specified Investments or Permitted Investments, as the case may be, in the register of the issuer of such Equipment Notes, Specified Investments or Permitted Investments, as the case may be. In no
event shall the Trustee invest in, or hold, Equipment Notes, Specified Investments or Permitted Investments in a manner that would cause the Trustee not to have the ownership interest in (or a securities entitlement with respect to) such Equipment
Notes, Specified Investments or Permitted Investments under the applicable provisions of the Uniform Commercial Code in effect where the Trustee holds such Equipment Notes, Specified Investments or Permitted Investments or other applicable law then
in effect. 
 Section 7.15 Representations and Warranties of Trustee. The Trustee hereby represents and warrants that: 

(a) the Trustee is a trust company duly organized and validly existing in good standing under the laws of the State of Delaware; 

(b) the Trustee has full power, authority and legal right to execute, deliver and perform this Agreement, any Intercreditor Agreement, any

(d) the execution, delivery and performance by the Trustee of this Agreement, any Intercreditor Agreement, any Liquidity Facility, the
Certificates and the Note Purchase Agreements will not require the authorization, consent, or approval of, the giving of notice to, the filing or registration with, or the taking of any other action in respect of, any governmental authority or
agency of the United States or the state of the United States where such Trustee is located and regulating the corporate trust activities of the Trustee, other than the filing of a Statement of Eligibility on Form T-1 in connection with the
registration of any Certificates; 
 (e) this Agreement, any Intercreditor Agreement, any Liquidity Facility, the Certificates and the Note
Purchase Agreements have been or will be duly executed and delivered by the Trustee and constitute or upon such execution and delivery will constitute the legal, valid and binding agreements of the Trustee, enforceable against it in accordance with

equity; and 
 (f) the statements made by it in a Statement of Eligibility on Form T-1 supplied or to be supplied to the Company in
connection with the registration of any Certificates are and will be true and accurate subject to the qualifications set forth therein; and that such statement complies and will comply in all material respects with the requirements of the Trust

Issuance Date, except as otherwise provided in the applicable Trust Supplement.

under this Agreement or under the Certificates of such series any and all withholding taxes applicable thereto as required by law. The Trustee agrees to act as such withholding agent and, in connection therewith, whenever any present or future taxes
or similar charges are required to be withheld with respect to any amounts payable in respect of the Certificates of such series, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the
Certificateholders of such series, that it will file any necessary withholding tax returns or statements when due, and that, as promptly as possible after the payment thereof, it 

  
 44 








 
will deliver to each such Certificateholder of such series appropriate documentation showing the payment thereof, together with such additional documentary evidence as such Certificateholders may
reasonably request from time to time. The Trustee agrees to file any other information reports as it may be required to file under United States law. 

Section 7.17 Trustee’s Liens. The Trustee in its individual capacity agrees that it will, in respect of each Trust created by this
Agreement, at its own cost and expense (and without right of indemnity hereunder, including Section 7.07), promptly take any action as may be necessary to duly discharge and satisfy in full any mortgage, pledge, lien, charge, encumbrance,

any creditor relationship listed in Section 311(b) of the Trust Indenture Act. If the Trustee shall resign or be removed as Trustee, it shall be subject to Section 311(a) of the Trust Indenture Act to the extent provided therein.

trustee except as expressly provided herein or in the related Trust Supplement.

such class of Certificates or a withdrawal or 

  
 48 








 
suspension of the rating of any class of Certificates, the Company shall provide the Trustee with an opinion of counsel (i) if an Event of Default shall have occurred and be continuing, to

will not cause the Trust to be treated as other than a grantor trust for United States federal income tax purposes. 
 Section 9.02
Supplemental Agreements with Consent of Certificateholders. With respect to each separate Trust and the series of Certificates relating thereto, with the consent of the Certificateholders holding Certificates of such series (including

 49 








 (5) cause any Trust to become an association taxable as a corporation for United
States federal income tax purposes.

ARTICLE X. 
 AMENDMENTS TO
INDENTURES AND OTHER NOTE DOCUMENTS 
 Section 10.01 Amendments and Supplements to Indentures and Other Note Documents. In the event
that the Trustee, as holder (or beneficial owner through the Subordination Agent) of any Equipment Notes (or as a prospective purchaser of any Postponed Notes) in trust for the benefit of the Certificateholders of any series or as Controlling Party
under an Intercreditor Agreement, receives (directly or indirectly through the Subordination Agent) a request for a consent to any amendment, modification, waiver or supplement under any Indenture or other


  
 50 








 
Note Document, subject to Section 9.01 hereof, the Trustee shall forthwith send a notice of such proposed amendment, modification, waiver or supplement to each Certificateholder of such
series registered on the Register as of the date of such notice. The Trustee shall request from the Certificateholders of such series a Direction as to (a) whether or not to take or refrain from taking (or direct the Subordination Agent to take
or refrain from taking) any action which a holder of (or, with respect to Postponed Notes, a prospective purchaser of) such Equipment Note has the option to direct, (b) whether or not to give or execute (or direct the Subordination Agent to
give or execute) any waivers, consents, amendments, modifications or supplements as a holder of (or, with respect to Postponed Notes, a prospective purchaser of) such Equipment Note or a Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a Postponed Note, its commitment to acquire such Postponed Note) if a vote has been called for with respect thereto. Provided such a request for Certificateholder Direction shall
have been made, in directing any action or casting any vote or giving any consent as the holder of any Equipment Note (or in directing the Subordination Agent in any of the foregoing), (i) other than as Controlling Party, the Trustee shall vote
for or give consent to any such action with respect to such Equipment Note (or Postponed Note) in the same proportion as that of (A) the aggregate face amount of all Certificates actually voted in favor of or for giving consent to such action
by such Direction of Certificateholders to (B) the aggregate face amount of all Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote as directed in such Certificateholder Direction by the Certificateholders of
such series evidencing a Fractional Undivided Interest aggregating not less than a majority in interest in the Trust. For purposes of the immediately preceding sentence, a Certificate shall have been “actually voted” if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder’s consent to such Direction prior to one Business Day before the Trustee directs such action or casts such vote or gives such consent. Notwithstanding the foregoing,
but subject to Section 6.04 and any Intercreditor Agreement, the Trustee may, with respect to the Certificates of any series, in its own discretion and at its own direction, consent and notify the relevant Loan Trustee of such consent (or
direct the Subordination Agent to consent and notify the Loan Trustee of such consent) to any amendment, modification, waiver or supplement under any related Indenture or any other related Note Document if an Event of Default hereunder shall have
occurred and be continuing or if such amendment, modification, waiver or supplement will not materially adversely affect the interests of the Certificateholders of such series. 

ARTICLE XI. 
 TERMINATION OF TRUSTS

 Section 11.01 Termination of the Trusts. In respect of each Trust created by the Basic Agreement as supplemented by a related
Trust Supplement, the respective obligations and responsibilities of the Company and the Trustee and, if applicable, the Parent with respect to such Trust shall terminate upon the distribution to all Holders of Certificates of the series of such
Trust and the Trustee of all amounts required to be distributed to them pursuant to this Agreement and the disposition of all property held as part of the Trust Property of such Trust; provided, however, that in no event shall such Trust continue
beyond the final expiration date determined as provided in such Trust Supplement. 

  
 51 








 Notice of any termination of a Trust, specifying the applicable Regular Distribution Date (or
applicable Special Distribution Date, as the case may be) upon which the Certificateholders of any series may surrender their Certificates to the Trustee for payment of the final distribution and cancellation, shall be mailed promptly by the Trustee
to Certificateholders of such series not earlier than 60 days and not later than 15 days preceding such final distribution specifying (i) the Regular Distribution Date (or Special Distribution Date, as the case may be) upon which the proposed
final payment of the Certificates of such series will be made upon presentation and surrender of Certificates of such series at the office or agency of the Trustee therein specified, (ii) the amount of any such proposed final payment, and
(iii) that the Record Date otherwise applicable to such Regular Distribution Date (or Special Distribution Date, as the case may be) is not applicable, payments being made only upon presentation and surrender of the Certificates of such series
at the office or agency of the Trustee therein specified. The Trustee shall give such notice to the Registrar at the time such notice is given to Certificateholders of such series. Upon presentation and surrender of the Certificates of such series
in accordance with such notice, the Trustee shall cause to be distributed to Certificateholders of such series amounts distributable on such Regular Distribution Date (or Special Distribution Date, as the case may be) pursuant to Section 4.02.

 In the event that all of the Certificateholders of such series shall not surrender their Certificates for cancellation within six months
after the date specified in the above-mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders of such series to surrender their Certificates for cancellation and receive the final distribution
with respect thereto. No additional interest shall accrue on the Certificates of such series after any Regular Distribution Date (or Special Distribution Date, as the case may be) of such series, as specified in the first written notice. In the
event that any money held by the Trustee for the payment of distributions on the Certificates of such series shall remain unclaimed for two years (or such lesser time as the Trustee shall be satisfied, after 60 days’ notice from the Company, is
one month prior to the escheat period provided under applicable law) after the final distribution date with respect thereto, the Trustee shall pay to each Loan Trustee the appropriate amount of money relating to such Loan Trustee for distribution as
provided in the applicable Indenture or other Note Documents and shall give written notice thereof to any related Owner Trustees and the Company. 

ARTICLE XII. 
 MISCELLANEOUS
PROVISIONS 
 Section 12.01 Limitation on Rights of Certificateholders. (a) The insolvency, death or incapacity of any
Certificateholder of any series shall not operate to terminate this Agreement or the related Trust, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or commence any proceeding in
any court for a partition or winding up of the Trust, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them. No Certificateholder of any series shall be entitled to revoke the related Trust.
