computational purposes. For purposes of such computations, the Certificates of any Class shall be deemed to be comprised of interest and principal components, with the principal component deemed to be the Pool Balance, and the interest component
deemed to equal interest accruing at the Stated Interest Rate for such Class of Certificates from the later of (1) the date of the issuance thereof and (2) the most recent but preceding Distribution Date to which such interest was
distributed to, but excluding, the applicable date of determination, such interest to be considered payable in arrears and to be calculated on the basis of a 360-day year comprised of twelve 30-day months. 

Section 2.02 Trust Accounts. (a) Upon the execution of this Agreement, the Subordination Agent shall establish and maintain
in its name (i) the Collection Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Trustees, the Certificateholders and the Liquidity
Providers, and (ii) as a sub-account in the Collection Account, the Special Payments Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the
Trustees, the Certificateholders and the Liquidity Providers. The Subordination Agent shall establish and maintain the Cash Collateral Accounts pursuant to and under the circumstances set forth in Section 3.05(f). Upon such establishment and
maintenance under Section 3.05(f), the Cash Collateral Accounts shall, together with the Collection Account, constitute the “Trust Accounts” hereunder. Without limiting the foregoing, all monies credited to the Trust Accounts shall
be, and shall remain, the property of the relevant Trust(s). 
 (b) Funds on deposit in the Trust Accounts shall be invested and reinvested
by the Subordination Agent in Eligible Investments selected by Spirit or its designated representative if such investments are reasonably available and have maturities no later than the earlier of (i) 90 days following the date of such
investment and (ii) the Business Day immediately preceding the Regular Distribution Date or the date of the related distribution pursuant to Section 2.04, as the case may be, next following the date of such investment; provided,
however, that, following the making of a Non-Extension Drawing under any Liquidity Facility, the Subordination Agent shall invest and reinvest the amounts in the applicable Cash Collateral Account in Eligible Investments pursuant to the
written instructions of the Liquidity Provider funding such Drawing, and provided further, however, that upon the occurrence and during the continuation of a Triggering Event, the Subordination Agent shall invest and reinvest the
amounts on deposit in the Trust Accounts (other than amounts in the Cash Collateral Accounts as a result of a Non-Extension Drawing, which shall be governed by the foregoing proviso) in Eligible Investments in accordance with the written
instructions of the Controlling Party. Unless otherwise expressly provided in this Agreement (including, without limitation, with respect to Investment Earnings on amounts on deposit in the Cash Collateral Accounts, Section 3.05(f)), any
Investment Earnings shall be deposited in the Collection Account when received by the Subordination Agent and shall be applied by the Subordination Agent in the same manner as the other amounts on deposit in the Collection Account are to be applied.
The Subordination Agent’s reasonable fees and expenses actually incurred in making such investments and any losses incurred in such investments shall be charged against the principal amount invested. The Subordination Agent shall not be liable
for any loss resulting from any investment, reinvestment or liquidation required to be made under this Agreement other than by reason of its willful misconduct or negligence. Eligible Investments and any other investment required to be made
hereunder shall be held to their maturities except that any such investment may be sold (without regard to its maturity) by the Subordination Agent without instructions whenever such sale is necessary to make a distribution required under this
Agreement. Uninvested funds held hereunder shall not earn or accrue interest. 
 (c) The Subordination Agent shall possess all right, title
and interest in all funds on deposit from time to time in the Trust Accounts and in all proceeds thereof (including all income thereon, except as otherwise expressly provided herein with respect to Investment Earnings). The Trust Accounts shall be
held in trust by the Subordination Agent under the sole dominion and control of the Subordination Agent for the benefit of the applicable Trustee, the applicable Certificateholders and the applicable Liquidity Provider, as the case may be. If, at
any time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the Subordination Agent shall within 10 Business Days (or such longer period, not to exceed 30 calendar days, to which a Rating Agency may consent) establish a new
Collection Account, Special Payments Account or Cash Collateral Account, as the case may be, as an Eligible Deposit Account and shall transfer any cash and/or any investments to such new Collection Account, Special Payments Account or Cash
Collateral Account, as the case may be. So long as the Subordination Agent is an Eligible Institution, the Trust Accounts shall be maintained with it as Eligible Deposit Accounts.

promptly calculate the amount of the proceeds of any redemption, purchase or prepayment of any Equipment Note or the amount of any Overdue Scheduled Payment or the proceeds of Equipment Notes or Collateral, as the case may be, comprising such
Special Payment under the applicable Indenture or Indentures and shall promptly send to each Trustee and the Liquidity Providers a Written Notice of such amount and the amount allocable to each Trust. Such Written Notice shall also set the

together with (without duplication) any other accrued and unpaid interest at the Stated Interest Rate on the outstanding principal amount of the Series A Equipment Notes held in the Class A Trust being redeemed, purchased or prepaid, in

(b) Investment of Amounts in Special Payments Account. Any amounts on deposit in the Special Payments Account prior to the distribution
thereof pursuant to Section 2.04 or 3.02 shall be invested in accordance with Section 2.02(b). Investment Earnings on such investments shall be distributed in accordance with Article III hereof. 

(c) Certain Payments. Except for amounts constituting Liquidity Obligations which shall be distributed as provided in
Section 3.02, the Subordination Agent will distribute promptly upon receipt thereof (i) any indemnity payment or expense reimbursement received by it from Spirit in respect of any Trustee, any Liquidity Provider, the Paying Agent, the
Depositary or the Escrow Agent (collectively, the “Payees”) and (ii) any compensation received by it from Spirit under any Operative Agreement in respect of any Payee, directly to the Person entitled thereto, provided

Default has occurred and is continuing thereunder, in taking, or refraining from taking, any action under such Indenture or with respect to the Equipment Notes issued thereunder by a Majority in Interest of Noteholders of such Equipment Notes
(provided that, for so long as the Subordination Agent is the registered holder of such Equipment Notes, the Subordination Agent shall act with respect to this clause (i) in accordance with the directions of the Trustees (in the case of
each such Trustee, with respect to the Equipment Notes issued under such Indenture and held as Trust Property of such Trust) constituting, in the aggregate, directions with respect to an outstanding principal amount of such Equipment Notes that, if

the Controlling Party and any vote so exercised shall be binding upon the Trustees and all Certificateholders. 
 The Subordination Agent
shall give Written Notice to all of the other parties to this Agreement promptly upon a change in the identity of the Controlling Party. Each of the parties hereto agrees that it shall not exercise any of the rights of the Controlling Party at such
time as it is not the Controlling Party hereunder; provided, however, that nothing herein contained shall prevent or prohibit any Non-Controlling Party from exercising such rights as shall be specifically granted to such
Non-Controlling Party hereunder and under the other Operative Agreements. 
 (c) Notwithstanding the foregoing, at any time after 18 months

18-month period.

such Unapplied Provider Advance or such Special Termination Advance, as the case may be, to the extent of such Investment Earnings. 
 (c)
If the Subordination Agent receives any Scheduled Payment after the Scheduled Payment Date relating thereto, but prior to such payment becoming an Overdue Scheduled Payment, then the Subordination Agent shall deposit such Scheduled Payment in the
Collection Account and promptly distribute such Scheduled Payment in accordance with the priority of distributions set forth in Section 3.02; provided that, for the purposes of this Section 3.03(c) only, each reference in clause
“ninth” and “eleventh” of Section 3.02 to “Distribution Date” shall be deemed to refer to such Scheduled Payment Date. 

Section 3.04 Payments to the Trustees and the Liquidity Providers. Any amounts distributed hereunder to any Liquidity Provider

 Section 3.05 Liquidity Facilities. (a) Interest Drawings. If on any
Distribution Date, after giving effect to the subordination provisions of this Agreement, the Subordination Agent shall not have sufficient funds for the payment of any amounts due and owing in respect of accrued interest on the Class A
Certificates or the Class B Certificates (at the Stated Interest Rate for such Class of Certificates) (other than any amount of interest which was due and payable in respect of the Class A Certificates or the Class B Certificates on such
Distribution Date but which remains unpaid due to the failure of the Depositary to pay any amount of accrued interest on the relevant Deposits on such Distribution Date), then, prior to 12:30 p.m. (New York City time) on such Distribution Date,
(i) the Subordination Agent shall request a drawing (each such drawing, an “Interest Drawing”) under the Liquidity Facility with respect to such Class of Certificates in an amount equal to the lesser of (x) an amount
sufficient to pay the amount of such accrued interest shortfall (at the applicable Stated Interest Rate for such Class of Certificates) and (y) the Available Amount under such Liquidity Facility, and (ii) the Subordination Agent shall upon
receipt of such amount pay such amount to the Trustee with respect to each such Class of Certificates in payment of such accrued interest shortfall. 

(b) Application of Interest Drawings. Notwithstanding anything to the contrary contained in this Agreement, (i) all payments
received by the Subordination Agent in respect of an Interest Drawing under the Class A Liquidity Facility and all amounts withdrawn by the Subordination Agent from the Class A Cash Collateral Account, and payable in each case to the
Class A Certificateholders or the Class A Trustee, shall be promptly distributed to the Class A Trustee, and (ii) all payments received by the Subordination Agent in respect of an Interest Drawing under the Class B Liquidity
Facility and all amounts withdrawn by the Subordination Agent from the Class B Cash Collateral Account, and payable in each case to the Class B Certificateholders or the Class B Trustee, shall be promptly distributed to the
Class B Trustee. 
 (c) Downgrade Drawings. (i) Each Liquidity Provider will promptly, but in any event within 10 days of
the occurrence of a Downgrade Event with respect to it (the date of such occurrence, the “Downgrade Date”), deliver notice to the Subordination Agent and Spirit of the occurrence of such Downgrade Event and the Downgrade Date
therefor. After the occurrence of a Downgrade Event with respect to any Liquidity Provider, each Liquidity Facility provided by such Liquidity Provider shall become a “Downgraded Facility” on the 35th day after the related Downgrade
Date, unless, not later than such 35th day (or, if earlier, the expiration date of such Downgraded Facility), the Rating Agency whose downgrading of such Liquidity Provider resulted in such Downgrade Event shall have provided a written
confirmation to the effect that the occurrence of such Downgrade Event will not result in the downgrading, withdrawal or suspension of the ratings then issued by such Rating Agency of the related Class of Certificates. Notwithstanding the foregoing,
if at any time after the occurrence of such Downgrade Event, such Liquidity Provider notifies the Subordination Agent in writing that no such confirmation will be provided by such Rating Agency, each Liquidity Facility provided by such Liquidity
Provider shall become a Downgraded Facility as of the date of such notice to the Subordination Agent. 
 (ii) If at any time any Liquidity
Facility becomes a Downgraded Facility, not later than the 35th day after the related Downgrade Date (or, if earlier, the expiration date of such Downgraded Facility), the Liquidity Provider under such Downgraded Facility or Spirit may arrange
for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility to the Subordination Agent in accordance with Section 3.05(e). 

(iii) If a Downgraded Facility has not been replaced by a Replacement Liquidity Facility in accordance with Section 3.05(c)(ii), the
Subordination Agent shall, on the 35th day referred to in Section 3.05(c)(ii) (or if such 35th day is not a Business Day, on the next succeeding Business Day)

(or, if earlier, the expiration date of such Downgraded Facility), request a drawing in accordance with and to the extent permitted by such Downgraded Facility (such drawing, a “Downgrade
Drawing”) of the Available Amount thereunder. Amounts drawn pursuant to a Downgrade Drawing shall be maintained and invested as provided in Section 3.05(f) hereof. Subject to Section 3.05(e)(iii), the applicable Liquidity Provider
may also arrange for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility at any time after such Downgrade Drawing so long as such Downgrade Drawing has not been reimbursed in full to such Liquidity Provider. 

(iv) For the avoidance of doubt, the provisions of this Section 3.05(c) shall apply to each occurrence of a Downgrade Event with respect
to a Liquidity Provider, regardless of whether or not one or more Downgrade Events have occurred prior thereto and whether or not any confirmation by a Rating Agency specified in Section 3.05(c)(i) has been obtained with respect to any prior
occurrence of a Downgrade Event. 
 (v) If, at any time after making a Downgrade Drawing, the applicable Liquidity Provider satisfies the
applicable Threshold Rating and delivers written notice to such effect to the Subordination Agent and Spirit, as of the second Business Day following receipt of such notice, (A) such Downgraded Facility shall cease to be a Downgraded Facility,
(B) the Subordination Agent shall withdraw the unapplied amount of such Downgrade Drawing on deposit in the applicable Cash Collateral Account and reimburse such amount to such Liquidity Provider, (C) any applied amount of such Downgrade
Drawing shall be deemed to have been converted to an Interest Drawing as of such date in accordance with the applicable Liquidity Facility, (D) the obligations of such Liquidity Provider shall be reinstated in accordance with the applicable
Liquidity Facility, and (E) the proviso in the definition of Available Amount shall no longer apply to such Downgrade Advance. 
 (d)
Non-Extension Drawings. If any Liquidity Facility with respect to any Class of Certificates is scheduled to expire on a date (the “Stated Expiration Date”) prior to the date that is 15 days after the Final Legal Distribution
Date for such Class of Certificates, then the following provisions shall apply: 
 (i) In the case of either initial Liquidity Facility or
any other Liquidity Facility having extension provisions identical to those set forth in Section 2.10 of either initial Liquidity Facility, then, if before the 25th day prior to any anniversary of the Closing Date (such 25th day, the
“Notice Date”), the Liquidity Provider shall have advised the Subordination Agent and Spirit that such Liquidity Facility shall not be extended beyond the immediately following anniversary date of the Closing Date and on or before
the Notice Date such Liquidity Facility shall not have been replaced in accordance with Section 3.05(e), the Subordination Agent shall, on the Notice Date (or as soon thereafter as possible but prior to the date of expiration of the expiring
Liquidity Facility (a “Non-Extended Facility”), in accordance with the terms of such Non-Extended Facility, request a drawing under such Non-Extended Liquidity Facility (such drawing, a
“Non-Extension Drawing”) of the Available Amount thereunder. 
 (ii) In the case of any other Liquidity Facility, no
earlier than the 60th day and no later than the 40th day prior to the then applicable Stated Expiration Date, the Subordination Agent shall request in writing that such Liquidity Provider extend the Stated Expiration Date to the earlier of
(i) the date that is 15 days after the Final Legal Distribution Date for such Class of Certificates and (ii) the date that is the day immediately preceding the 364th day after the last day of the Consent Period (unless the obligations of
such Liquidity Provider thereunder are earlier terminated in accordance with such Liquidity Facility). Whether or not the applicable Liquidity Provider has received a request from the Subordination Agent, such Liquidity Provider shall by notice (the
“Consent Notice”) to the Subordination Agent, during the period commencing on the date that is 60 days prior to the then effective Stated Expiration Date (or if earlier, the date of such Liquidity Provider’s receipt of such
request, if any, from the Subordination Agent) and ending on the date that is 25 days prior to such Stated Expiration Date (the “Consent Period”)

advise the Subordination Agent whether, in its sole discretion, it agrees to so extend the Stated Expiration Date; provided, that such extension shall not be effective with respect to such
Liquidity Provider if, by notice (the “Withdrawal Notice”) to the Subordination Agent prior to the end of the Consent Period, such Liquidity Provider revokes its Consent Notice. If a Liquidity Provider advises the Subordination
Agent on or before the end of the Consent Period that such Stated Expiration Date shall not be so extended or fails to irrevocably and unconditionally advise the Subordination Agent on or before the end of the Consent Period that such Stated
Expiration Date shall be so extended or gives a Withdrawal Notice to the Subordination Agent prior to the end of the Consent Period (and, in each case, if such Liquidity Provider shall not have been replaced in accordance with Section 3.05(e)),
the Subordination Agent shall, on the date on which the Consent Period ends (or as soon as possible thereafter but prior to the Stated Expiration Date), in accordance with and to the extent permitted by the terms of the Non-Extended Facility,
request a Non-Extension Drawing under such Non-Extended Facility of the Available Amount thereunder. 
 (iii) Amounts drawn pursuant to a
Non-Extension Drawing shall be maintained and invested in accordance with Section 3.05(f). 
 (e) Issuance of Replacement Liquidity
Facility. (i) Subject to Section 3.05(e)(iii) and the agreements, if any, in the applicable Fee Letter, at any time, Spirit may, at its option, with cause or without cause, arrange for a Replacement Liquidity Facility to replace any
Liquidity Facility for any Class of Certificates (including any Replacement Liquidity Facility provided pursuant to Section 3.05(e)(ii)); provided, however, that if the initial Liquidity Provider is replaced (including as a result
of issuance of Refinancing Certificates in respect of the Class B Certificates) it shall be replaced with respect to all Liquidity Facilities under which it is a Liquidity Provider; provided, further, that the initial Liquidity
Provider shall not be replaced by Spirit as a Liquidity Provider with respect to such Liquidity Facility without the consent of such Liquidity Provider during the period prior to the third anniversary of the Closing Date unless (A) there shall
have become due to such initial Liquidity Provider, or such initial Liquidity Provider shall have demanded, amounts pursuant to Section 3.01 or 3.03 of any applicable Liquidity Facility or Spirit determines in good faith that there is a
substantial likelihood that such initial Liquidity Provider will have the right to claim any such amounts (unless such initial Liquidity Provider waives, in writing, any right it may have to claim such amounts), which determination shall be set
forth in a certificate delivered by Spirit to such initial Liquidity Provider setting forth the basis for such determination, (B) it shall become unlawful or impossible for such initial Liquidity Provider to maintain or fund its LIBOR Advances
as described in Section 3.10 of any Liquidity Facility, (C) any Liquidity Facility of such initial Liquidity Provider shall become a Downgraded Facility or a Non-Extended Facility or a Downgrade Drawing or a Non-Extension Drawing shall
have occurred under any Liquidity Facility of such initial Liquidity Provider or (D) such initial Liquidity Provider shall have breached any of its payment (including, without limitation, funding) obligations under any Liquidity Facility in
respect of which it is the Liquidity Provider. If such Replacement Liquidity Facility is provided at any time after a Downgrade Drawing, a Non-Extension Drawing or a Special Termination Drawing has been made, all funds on deposit in the relevant
Cash Collateral Account resulting from such Downgrade Drawing, Non-Extension Drawing or Special Termination Drawing will be returned to the Liquidity Provider being replaced. 

(ii) If any Liquidity Provider shall determine not to extend its Liquidity Facility in accordance with Section 3.05(d), then such
Liquidity Provider may, at its option, arrange for a Replacement Liquidity Facility to replace such Liquidity Facility during the period no earlier than 40 days and no later than 25 days prior to the then effective Stated Expiration Date of such
Liquidity Facility. At any time after a Non-Extension Drawing has been made under any Liquidity Facility, the Liquidity Provider thereunder may, at its option and its own expense, arrange for a Replacement Liquidity Facility to replace the Liquidity
Facility under which such Non-Extension Drawing has been made.

 (iii) No Replacement Liquidity Facility arranged by Spirit or a Liquidity Provider in accordance
with clause (i) or (ii) above or pursuant to Section 3.05(c), respectively, shall become effective and no such Replacement Liquidity Facility shall be deemed a “Liquidity Facility” under the Operative Agreements, unless and
until (A) each of the conditions referred to in sub-clauses (iv)(x) and (z) below shall have been satisfied, (B) if such Replacement Liquidity Facility shall materially adversely affect the rights, remedies, interests or
obligations of the Class A Certificateholders or the Class B Certificateholders under any of the Operative Agreements, the applicable Trustee shall have consented, in writing, to the execution and issuance of such Replacement Liquidity
Facility and (C) in the case of a Replacement Liquidity Facility arranged by a Liquidity Provider under Section 3.05(e)(ii) or pursuant to Section 3.05(c), such Replacement Liquidity Facility is reasonably acceptable to Spirit. 

(iv) In connection with the issuance of each Replacement Liquidity Facility, the Subordination Agent shall (x) prior to the issuance of
such Replacement Liquidity Facility, obtain written confirmation from each Rating Agency to the effect that such Replacement Liquidity Facility will not cause a reduction, withdrawal or suspension of any rating then in effect for the related Class
of Certificates by such Rating Agency (without regard to any downgrading of any rating of the Liquidity Provider being replaced pursuant to Section 3.05(c)), (y) pay all Liquidity Obligations then owing to the replaced Liquidity Provider
(which payment shall be made first from available funds in the applicable Cash Collateral Account as described in Section 3.05(f), and thereafter from any other available source, including, without limitation, a drawing under the Replacement
Liquidity Facility) and (z) cause the issuer of the Replacement Liquidity Facility to deliver the Replacement Liquidity Facility to the Subordination Agent, together with a legal opinion opining that such Replacement Liquidity Facility is an
enforceable obligation of such Replacement Liquidity Provider. 
 (v) Upon satisfaction of the conditions set forth in clauses (iii)
and (iv) of this Section 3.05(e) with respect to a Replacement Liquidity Facility, (1) the replaced Liquidity Facility shall terminate, (2) the Subordination Agent shall, if and to the extent so requested by Spirit or the
Liquidity Provider being replaced, execute and deliver any certificate or other instrument required in order to terminate the replaced Liquidity Facility, shall surrender the replaced Liquidity Facility to the Liquidity Provider being replaced and
shall execute and deliver the Replacement Liquidity Facility and any associated Fee Letter, (3) each of the parties hereto shall enter into any amendments to this Agreement necessary to give effect to (a) the replacement of the applicable
Liquidity Provider with the applicable Replacement Liquidity Provider and (b) the replacement of the applicable Liquidity Facility with the applicable Replacement Liquidity Facility, and (4) the applicable Replacement Liquidity Provider
shall be deemed to be a Liquidity Provider with the rights and obligations of a Liquidity Provider hereunder and under the other Operative Agreements and such Replacement Liquidity Facility shall be deemed to be a Liquidity Facility hereunder and
under the other Operative Agreements. 
 (vi) Spirit shall be responsible for all fees and expenses related to its arranging a Replacement
Liquidity Facility pursuant to Section 3.05(e)(i) (including a Replacement Liquidity Facility for a Non-Extended Facility) but excluding (x) any replacement at any time, whether arranged by Spirit or the Liquidity Provider being replaced,
of a Downgraded Facility or (y) any replacement, whether arranged by Spirit or the Liquidity Provider being replaced, following any event described in clause (D) of the second proviso to the first sentence of Section 3.05(e)(i), in
each case regardless of whether such replacement occurs before or after the third anniversary of the Closing Date. The Liquidity Provider being replaced shall be responsible for all fees and expenses related to its arranging a Replacement Liquidity
Facility pursuant to Section 3.05(e)(ii), or any replacement pursuant to clause (x) or (y) of the immediately preceding sentence, provided, that the fees and expenses for which such Liquidity Provider is responsible shall in
any case not include any ongoing fees or expenses of the Replacement Liquidity Provider (for the avoidance of doubt, in each case, such fees and expenses shall include upfront fees, structuring fees or similar fees (if any) payable to the
Replacement Liquidity Provider.

Agent shall draw all Available Amounts under the Class A Liquidity Facility or the Class B Liquidity Facility pursuant to Section 3.05(c), 3.05(d), 3.05(i) or 3.05(k), or in the event amounts are to be deposited in the Class A
Cash Collateral Account or the Class B Cash Collateral Account pursuant to subclause (A) or (B) of clause “fourth” of Section 3.02, amounts so drawn or to be deposited, as the case may be, shall be deposited by the
Subordination Agent in the Class A Cash Collateral Account or the Class B Cash Collateral Account, as applicable. All amounts on deposit in each Cash Collateral Account shall be invested and reinvested in Eligible Investments in accordance

Distribution Date but which remains unpaid due to the failure of the Depositary to pay any amount of accrued interest on the relevant Deposits on such Distribution Date) after giving effect to the subordination provisions of this Agreement, withdraw
from the Class A Cash Collateral Account, and pay to the Class A Trustee, an amount equal to the lesser of (x) an amount necessary to pay accrued and unpaid interest (at the Stated Interest Rate for the Class A Certificates) on

 (iii) on each date on which the Pool Balance of the Class A Trust shall have
been reduced by payments made to the Class A Certificateholders pursuant to Section 3.02 hereof or pursuant to Section 2.03 of the Escrow and Paying Agent Agreement for such Class, the Subordination Agent shall withdraw from the
Class A Cash Collateral Account such amount as is necessary so that, after giving effect to the reduction of the Pool Balance on such date (and any reduction in the amounts on deposit in the Class A Cash Collateral Account resulting from a
prior withdrawal of amounts on deposit in the Class A Cash Collateral Account on such date) and any transfer of Investment Earnings from such Cash Collateral Account to the Collection Account or the Special Payments Account on such date, an

giving effect to any such transfer of Investment Earnings) will remain on deposit in the Class A Cash Collateral Account and shall first, pay such withdrawn amount to the Class A Liquidity Provider until the Class A Liquidity
Obligations owing to the Class A Liquidity Provider shall have been paid in full, and second, deposit any remaining withdrawn amount in the Collection Account;

Class B Certificateholders pursuant to Section 3.02 hereof or pursuant to Section 2.03 of the Escrow and Paying Agent Agreement for such Class, the Subordination Agent shall withdraw from the Class B Cash Collateral Account such

the applicable Threshold Rating and delivers written notice to such effect to the Subordination Agent and Spirit, on the second Business Day following receipt of such notice, the Subordination Agent shall withdraw all amounts remaining on deposit in
the applicable Cash Collateral Account constituting the unapplied amount of any Downgrade Drawing and shall pay such amounts to such Liquidity Provider and the obligations of such Liquidity Provider shall be reinstated in accordance with the
applicable Liquidity Facility; and 
 (vii) following (x) the payment of Final Distributions or (y) the Final Legal

 (g) Reinstatement. With
respect to any Interest Drawing under the Liquidity Facility for any relevant Trust, upon the reimbursement of the applicable Liquidity Provider for all or any part of the amount of such Interest Drawing, together with any accrued interest thereon,
the Available Amount of such Liquidity Facility shall be reinstated by an amount equal to the amount of such Interest Drawing so reimbursed to the applicable Liquidity Provider but not to exceed the Stated Amount for such Liquidity Facility;
provided, however, that the Available Amount of such Liquidity Facility shall not be so reinstated in part or in full pursuant to the foregoing provisions of this Section 3.05(g) at any time if (x) both a Performing Note
Deficiency exists and a Liquidity Event of Default shall have occurred and be continuing with respect to the relevant Liquidity Facility or (y) a Final Drawing, Downgrade Drawing, Non-Extension Drawing or Special Termination Drawing shall have
occurred with respect to such Liquidity Facility or an Interest Drawing shall have been converted into a Final Drawing. Notwithstanding anything to the contrary, in the event that, with respect to any particular Liquidity Facility, (i) funds
are withdrawn from the related Cash Collateral Account pursuant to clause (i) or (ii) of Section 3.05(f) or (ii) such Liquidity Facility shall become a Downgraded Facility or a Non-Extended Facility at a time when unreimbursed
Interest Drawings under such Liquidity Facility have reduced the Available Amount thereunder to zero, then funds received by the Subordination Agent at any time, other than (x) any time when both a Performing Note Deficiency exists and a
Liquidity Event of Default shall have occurred and be continuing with respect to such Liquidity Facility or (y) any time after a Final Drawing shall have occurred with respect to such Liquidity Facility or an Interest Drawing for such Liquidity
Facility shall have been converted into a Final Drawing, shall be deposited in such Cash Collateral Account as and to the extent provided in clause “fourth” of Section 3.02 and applied in accordance with Section 3.05(f). 

(h) Reimbursement. The amount of each drawing under the Liquidity Facilities shall be due and payable, together with interest thereon,

Liquidity Provider of a Termination Notice with respect to its applicable Liquidity Facility, the Subordination Agent shall, not later than the date specified in such Termination Notice, in accordance with the terms of such Liquidity Facility,

(j) Adjustments of Stated Amount. Promptly following each date on which the Required Amount of the Liquidity Facility for a relevant
Class of Certificates is reduced as a result of a reduction in the Pool Balance with respect to such Certificates or otherwise, the Subordination Agent shall, if any such Liquidity Facility provides for reductions of the Stated Amount of such
Liquidity Facility and if such reductions are not automatic, request such Liquidity Provider for such Class of Certificates to reduce such Stated Amount to an amount equal to the Required Amount with respect to such Liquidity Facility (as calculated
by the Subordination Agent after giving effect to such payment). Each such request shall be made in accordance with the provisions of the applicable Liquidity Facility.

ARTICLE IV 
 EXERCISE OF
REMEDIES 
 Section 4.01 Directions from the Controlling Party. (a) (i) Following the occurrence and during the
continuation of an Indenture Event of Default under any Indenture, the Controlling Party shall direct the Subordination Agent, as the holder of the Equipment Notes issued under such Indenture, which in turn shall direct the Loan Trustee under such
Indenture, in the exercise of remedies available to the holders of such Equipment Notes, including, without limitation, the ability to vote all such Equipment Notes held by the Subordination Agent in favor of Accelerating such Equipment Notes in
accordance with the provisions of such Indenture. Subject to Section 4.01(a)(iii), if the Equipment Notes issued pursuant to any Indenture have been Accelerated following an Indenture Event of Default with respect thereto, the Controlling Party
may direct the Subordination Agent to sell, assign, contract to sell or otherwise dispose of and deliver all (but not less than all) of such Equipment Notes to any Person at public or private sale, at any location at the option of the Controlling
Party, all upon such terms and conditions as the Controlling Party may reasonably deem advisable and in accordance with applicable law. 

(ii) Following the occurrence and during the continuation of an Indenture Event of Default under any Indenture, in the exercise of remedies
pursuant to such Indenture, the Loan Trustee under such Indenture may be directed to lease the related Aircraft to any Person (including Spirit) so long as the Loan Trustee in doing so acts in a “commercially reasonable” manner within the
meaning of Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof). 

(iii) Notwithstanding the foregoing, so long as any Certificates remain Outstanding, during the period ending on the date which is nine months

Certificates of which are held or beneficially owned by Spirit and/or its Affiliates), no Aircraft subject to the Lien of such Indenture or such Equipment Notes may be sold if the net proceeds from such sale would be less than the Minimum Sale Price
for such Aircraft or such Equipment Notes. 
 (iv) Upon the occurrence and continuation of an Indenture Event of Default under any
Indenture, the Subordination Agent will obtain three desktop appraisals from the Appraisers selected by the Controlling Party setting forth the current market value, current lease rate and distressed value (in

“Appraisal” and the current market value appraisals being referred to herein as the “Post-Default Appraisals”). For so long as any Indenture Event of Default shall be continuing under any Indenture, and without
limiting the right of the Controlling Party to request more frequent Appraisals, the Subordination Agent will obtain updated Appraisals on the date that is 364 days from the date of the most recent Appraisal (or if a Spirit Bankruptcy Event shall

reasonable efforts as the Subordination Agent may deem appropriate to make such Appraisals available to all Certificateholders. 
 (b)
Following the occurrence and during the continuance of an Indenture Event of Default under any Indenture, the Controlling Party shall take such actions as it may reasonably deem most effectual to complete the sale or other disposition of the
relevant Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment, contract to sell or other disposition, the Controlling Party may maintain or cause the Subordination Agent to maintain possession of such Equipment Notes and

Controlling Party may direct the Subordination Agent to, subject to the terms and conditions of the related Indenture, instruct the Loan Trustee under such Indenture to foreclose on the Lien on the related Aircraft or to take any other remedial
action permitted under such Indenture or under any applicable law. 
 (c) If following a Spirit Bankruptcy Event and during the pendency

restructuring proposal on DTC’s Internet bulletin board or make such other commercially reasonable efforts as the Subordination Agent may deem appropriate to make such terms and conditions available to all Certificateholders. Thereafter,
neither the Subordination Agent nor any Trustee, whether acting on instructions of the Controlling Party or otherwise, may, without the consent of each Trustee and each Liquidity Provider that has not made a Final Drawing, enter into any term sheet,
stipulation or other agreement (a “Restructuring Arrangement”) (whether in the form of an adequate protection stipulation, an extension under Section 1110(b) of the Bankruptcy Code or otherwise) to effect any such restructuring
proposal with or on behalf of Spirit unless and until the material economic terms and conditions of such restructuring proposal shall have been made available to all Certificateholders and each Liquidity Provider that has not made a Final Drawing
for a period of not less than 15 calendar days (except that such requirement shall not apply to any such term sheet, stipulation or other agreement that is to be effective on or as of any date occurring during the 60-Day Period and that is initially

Restructuring Arrangement with respect to which such provisions have been complied with in connection with the original entry thereof if the possibility of such extension has been disclosed in satisfaction of the notification requirements of such
provisions and such extension shall not amend or modify any of the other terms and conditions of such Restructuring Arrangement and (ii) shall apply to the initial extension of an Interim Restructuring Arrangement beyond the three months
following the expiry of the 60-Day Period but not to any subsequent extension of such Interim Restructuring Arrangement, if the possibility of such subsequent extension has been disclosed in satisfaction of the notification requirements of such
provisions and such subsequent extension shall not amend or modify any of the other terms and conditions of such Interim Restructuring Arrangement. In

hereafter existing at law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may, subject always to the terms and conditions hereof, be exercised from time to time and as
often and in such order as may be deemed expedient by any Trustee, any Liquidity Provider, the Controlling Party or the Subordination Agent, as appropriate, and the exercise or the beginning of the exercise of any right, power or remedy shall not be
construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by any Trustee, any Liquidity Provider, the Controlling Party or the Subordination Agent in the exercise of any
right, remedy or power or in the pursuit of any remedy shall, to the extent permitted by applicable law, impair any such right, power or remedy or be construed to be a waiver of any default or to be an acquiescence therein. 

Section 4.03 Discontinuance of Proceedings. In case any party to this Agreement (including the Controlling Party in such capacity)
shall have instituted any Proceeding to enforce any right, power or remedy under this Agreement by foreclosure, entry or otherwise, and such Proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely
to the Person instituting such Proceeding, then and in every such case each such party shall, subject to any determination in such Proceeding, be restored to its former position and rights hereunder, and all rights, remedies and powers of such party
shall continue as if no such Proceeding had been instituted.

Agent in such event being referred to herein as the retiring Subordination Agent), the Controlling Party (or the party that would be the Controlling Party if an Indenture Event of Default had occurred) shall promptly appoint a successor
Subordination Agent. If a successor Subordination Agent shall not have been appointed within 60 days after such notice of resignation or removal, the retiring Subordination Agent, one or more of the Trustees or one or more of the Liquidity Providers
may petition any court of competent jurisdiction for the appointment of a successor Subordination Agent to act until such time, if any, as a successor shall have been appointed as provided above. 

A successor Subordination Agent shall deliver (x) a written acceptance of its appointment as Subordination Agent hereunder to the
retiring Subordination Agent and (y) a written assumption of its obligations hereunder and under each Liquidity Facility to each party hereto, upon which the resignation or removal of the retiring Subordination Agent shall become effective, and

to the successor Subordination Agent. 
 If the Subordination Agent fails to comply with Section 6.09 (to the extent applicable), one
or more of the Trustees or one or more of the Liquidity Providers may petition a court of competent jurisdiction for the removal of the Subordination Agent and the appointment of a successor Subordination Agent. 

Notwithstanding the foregoing, no resignation or removal of the Subordination Agent shall be effective unless and until a successor has been
appointed. No appointment of a successor Subordination Agent shall be effective unless and until the Rating Agencies shall have delivered a Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies.

which it may be consolidated, or any corporation, bank, trust company or other financial institution resulting from any merger, conversion or consolidation to which the Subordination Agent shall be a party, or any corporation, bank, trust company or
other financial institution succeeding to all or substantially all of the corporate trust business of the Subordination Agent, shall be the successor of the Subordination Agent hereunder, provided that such corporation, bank, trust company or
other financial institution shall be otherwise qualified and eligible under Section 6.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto, except that such corporation, bank, trust
company or other financial institution shall give prompt notice of such transaction to the Liquidity Providers and Spirit.

Liquidity Obligations and the Class A Certificates and (B) in the case of any Refinancing Certificates issued in respect of any Additional Certificates, the Administration Expenses, the Liquidity Obligations, the Class A
Certificates, the Class B Certificates and, if applicable, any other class of Additional Certificates that rank senior, in priority of payment of “Expected Distributions” under this Agreement, to such Refinancing Certificates. Such
issuance of Refinancing Equipment Notes and Refinancing Certificates and the amendment of this Agreement as provided below shall require Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies and shall not
materially adversely affect any of the Trustees in their individual capacities or any of the Liquidity Providers. This Agreement shall be amended by written agreement of Spirit and the Subordination Agent to give effect to the issuance of any
Refinancing Certificates subject to the following terms and conditions: 
 (i) the Refinancing Trustee shall be added as a
party to this Agreement; 
 (ii) the definitions of “Certificate”, “Class”, “Class B
Certificates”, “Final Legal Distribution Date”, “Trust”, “Trust Agreement” and “Controlling Party” (and such other applicable definitions) shall be revised, as appropriate, to reflect such issuance (and
the subordination, as applicable, of the Refinancing Certificates and the Refinancing Equipment Notes); 
  

Intercreditor Agreement (2015-1) 

(Spirit 2015-1 EETC) 

  
 43 








 (iii) the Refinancing Certificates may have the benefit of credit support similar
to the Liquidity Facilities or different therefrom and claims for fees, interest, expenses, reimbursement of advances and other obligations arising from such credit support (A) in the case of any Refinancing Certificates issued in respect of
the Class B Certificates, may rank pari passu with similar claims in respect of the Liquidity Facilities and (B) in the case of any Refinancing Certificates issued in respect of any Additional Certificates, shall be subordinated, at
least, to the Administration Expenses, the Liquidity Obligations, the Class A Certificates and the Class B Certificates; provided that, (x) in each case, Ratings Confirmation with respect to each Class of Certificates then rated by
the Rating Agencies shall have been obtained and (y) in the case of clause (A) the prior written consent of the Class A Liquidity Provider shall have been obtained; 

(iv) the Refinancing Certificates cannot be issued to Spirit but may be issued to any of Spirit’s Affiliates so long as
such Affiliate shall have bankruptcy remote and special purpose provisions in its certificate of incorporation or other organizational documents and any subsequent transfer of such Refinancing Certificates from such Affiliate to any other Affiliate
of Spirit shall be similarly restricted; and 
 (v) the scheduled payment dates on the Refinancing Equipment Notes shall be
the Regular Distribution Dates. 
 The issuance of the Refinancing Certificates in compliance with all of the foregoing terms in clauses
(i) to (v) of this Section 8.01(c) shall be deemed to not materially adversely affect any of the Trustee’s rights and obligations and shall not require the consent of any of the Trustees or the holders of any Class of
Certificates. Each of the Liquidity Providers hereby agrees and confirms that it shall be deemed to consent to any issuance and amendment in accordance with this Section 8.01(c) (subject to the Class A Liquidity Provider’s consent
right in clause (y) to the proviso to Section 8.01(c)(iii)) and that any such issuance and amendment shall not affect any of its respective obligations under the applicable Liquidity Facility, provided that a condition to the
issuance of any Refinancing Certificates issued in respect of a Class of Certificates with a Liquidity Facility shall be the payment in full of all amounts owed to the Liquidity Provider under such Liquidity Facility and the termination of such
Liquidity Facility upon the issuance of such Refinancing Certificates. The Subordination Agent shall deliver to each Trustee and each Liquidity Provider (other than the Liquidity Provider of such terminated Liquidity Facility) a copy of the
amendments made to this Agreement and all opinions, certificates and other documents delivered in connection with the issuance of any Refinancing Certificates. 

(d) Pursuant to the terms of Section 2.02 of each applicable Indenture and Section 4(a)(v) of the Note Purchase Agreement, one or
more additional series of Equipment Notes (the “Additional Equipment Notes”), which shall be subordinated in right of payment to the Series A Equipment Notes, the Series B Equipment Notes and, if applicable, one or more series
of Additional Equipment Notes under such Indenture, may be issued at any time and from time to time with respect to any or all of the Aircraft. If any series of Additional Equipment Notes are issued under any Indenture, each such series of
Additional Equipment Notes shall be issued to a new pass through trust (an “Additional Trust”) that issues a class of pass through certificates (the “Additional Certificates”) to certificateholders (each, an
“Additional Certificateholder”) pursuant to a pass through trust agreement (an “Additional Trust Agreement”) with a trustee (an “Additional Trustee”). In such case, this Agreement, including without
limitation Sections 2.04, 3.01 and 3.02 hereof, shall be amended by written agreement of Spirit and the Subordination Agent to provide for the subordination of such class of Additional Certificates to, and to provide for distributions on the
Additional Certificates after payment of, the Administration Expenses, the Liquidity Obligations, the Class A Certificates, the Class B Certificates and, 
  

Intercreditor Agreement (2015-1) 

(Spirit 2015-1 EETC) 

  
 44 








 
if applicable, any other Additional Certificates that rank senior, in priority of payment of “Expected Distributions” under this Agreement, to such Additional Certificates (subject to
clause (iii) below). Such issuance, and the amendment of this Agreement as provided below shall require Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies and shall not materially adversely affect
any of the Trustees in their individual capacities or any of the Liquidity Providers. This Agreement shall be amended by written agreement of Spirit and the Subordination Agent to give effect to the issuance of any Additional Certificates subject to
the following terms and conditions: 
 (i) the Additional Trustee shall be added as a party to this Agreement; 

(ii) the definitions of “Certificate”, “Class”, “Equipment Notes”, “Final Legal Distribution
Date”, “Trust”, “Trust Agreement”, and “Controlling Party” (and such other applicable definitions) shall be revised, as appropriate, to reflect the issuance of the Additional Certificates (and the subordination
thereof); 
 (iii) Section 3.02 may be revised, with respect to any class of Additional Certificates, to provide for the
distribution of “Adjusted Interest” for such class of Additional Certificates (calculated in a manner substantially similar to the calculation of Class B Adjusted Interest) after the Class B Adjusted Interest (and, if applicable, after any
“Adjusted Interest” for any Additional Certificates that rank senior, in priority of payment of “Expected Distributions” under this Agreement, to such Additional Certificates) but before Expected Distributions on the Class A
Certificates; 
 (iv) the Additional Certificates may have the benefit of credit support similar to the Liquidity Facilities
or different therefrom, provided that (A) claims for fees, interest, expenses, reimbursement of advances and other obligations arising from such credit support shall be subordinated, at least, to the Administration Expenses, the
Liquidity Obligations, the Class A Certificates and the Class B Certificates and (B) Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies shall have been obtained; 

(v) the Additional Certificates may be rated by the Rating Agencies; 

(vi) the Additional Certificates cannot be issued to Spirit but may be issued to any of Spirit’s Affiliates so long as
such Affiliate shall have bankruptcy remote and special purpose provisions in its certificate of incorporation or other organizational documents and any subsequent transfer of such Additional Certificates from such Affiliate to any other Affiliate
of Spirit shall be similarly restricted; 
 (vii) the scheduled payment dates on such series of Additional Equipment Notes
shall fall on a Regular Distribution Date; and 
 (viii) for the avoidance of doubt and without limitation of the foregoing,
in the event that any Additional Certificates are issued prior to the Delivery Period Termination Date, the definitions of Deposit Agreement, Escrow and Paying Agent Agreement, Escrow Agent, Escrow Receipts, Paying Agent, Paying Agent Account,
Expected Distributions, Final Distributions and Pool Balance (and any other applicable definition) and the related provisions hereof may be appropriately revised to reflect any applicable deposit and escrow arrangement in relation to such Additional
Certificates. 
 The issuance of the Additional Certificates in compliance with all of the foregoing terms in clauses (i) to
(viii) of this Section 8.01(d) shall be deemed to not materially adversely affect any of the Trustee’s rights and obligations and shall not require the consent of any of the Trustees or the holders of any Class of Certificates. Each
of the Liquidity Providers hereby agrees and confirms that it shall be 
  

Intercreditor Agreement (2015-1) 

(Spirit 2015-1 EETC) 

  
 45 








 
deemed to consent to any issuance and amendment in accordance with this Section 8.01(d) and that any such issuance and amendment shall not affect any of its respective obligations under the
applicable Liquidity Facility. The Subordination Agent shall deliver to each Trustee and each Liquidity Provider a copy of the amendments made to this Agreement and all opinions, certificates and other documents delivered in connection with the
issuance of any Additional Certificates. 
 Section 8.02 Subordination Agent Protected. If, in the reasonable opinion of the
institution acting as the Subordination Agent hereunder, any document required to be executed by it pursuant to the terms of Section 8.01 adversely affects any right, duty, immunity or indemnity with respect to such institution under this
Agreement or any Liquidity Facility, the Subordination Agent may in its discretion decline to execute such document.

respective rights, limitations of rights, obligations, duties and immunities under this Agreement of the parties hereto and beneficiaries hereof shall thereafter be determined, exercised and enforced hereunder subject in all respects to such

permitted by this Agreement. 
 Section 8.04 Notice to Rating Agencies. Promptly following its receipt of each amendment,
consent, modification, supplement or waiver contemplated by this Article VIII, the Subordination Agent shall send a copy thereof to each Rating Agency.

enforceable by, each of the parties hereto and the successors and permitted assigns of each, all as herein provided. In addition, the Spirit Provisions shall inure to the benefit of Spirit and its successors and permitted assigns, and (without

 Section 9.09
Subordination. (a) As between the Liquidity Providers (and any additional liquidity providers in respect of any class of Refinancing Certificates or any Additional Certificates), on the one hand, and the Trustees (and any Refinancing
Trustees or any Additional Trustees) and the Certificateholders (and any Refinancing Certificateholders or any Additional Certificateholders), on the other hand, and as among the Trustees (and any Refinancing Trustees or any Additional Trustee) and
the related Certificateholders (and any Refinancing Certificateholders or any Additional Certificateholders) this Agreement shall be a subordination agreement for purposes of Section 510 of the Bankruptcy Code. 

(b) Notwithstanding the provisions of this Agreement, if prior to the payment in full to the Liquidity Providers of all Liquidity Obligations
then due and payable any party hereto shall have received any payment or distribution in respect of Equipment Notes or any other amount under the Indentures or other Operative Agreements which, had the subordination provisions of this Agreement been
properly applied to such payment, distribution or other amount, would not have been distributed to such Person, then such payment, distribution or other amount shall be received and held in trust by such Person and paid over or delivered to the

 (c) If any Trustee, any Liquidity Provider or the Subordination Agent receives
any payment in respect of any obligations owing or amounts distributable hereunder (or, in the case of the Liquidity Providers, in respect of the Liquidity Obligations), which is subsequently invalidated, declared preferential, set aside and/or
required to be repaid to a trustee, receiver or other party, then, to the extent of such payment, such obligations or amounts (or, in the case of the Liquidity Providers, such Liquidity Obligations) intended to be satisfied shall be revived and
continue in full force and effect as if such payment had not been received. 
 (d) The Trustees (on behalf of themselves and the holders of
Certificates), the Liquidity Providers and the Subordination Agent expressly confirm and agree that the payment priorities and subordination specified in Articles II and III shall apply in all circumstances, notwithstanding (x) the fact

being expressly agreed that the payment priorities and 
  
 Intercreditor
Agreement (2015-1)

 48 








 
subordination specified in Articles II and III shall apply whether or not a claim for post-petition or post-filing interest is allowed in the proceedings resulting from such Spirit
Bankruptcy Event or other event or occurrence). The Trustees expressly agree (on behalf of themselves and the holders of Certificates) not to assert priority over the holders of Liquidity Obligations (except as specifically set forth in
Section 3.02) due to their status as secured creditors in any bankruptcy, insolvency or other legal proceeding. 
 (e) Each of the
Trustees (on behalf of themselves and the holders of Certificates), the Liquidity Providers and the Subordination Agent may take any of the following actions without impairing its rights under this Agreement:

 (ii) obtain the primary or secondary obligation of any other obligor with respect to
any amounts owing to it hereunder, including, in the case of the Liquidity Providers, any of the Liquidity Obligations;

Providers, any of the Liquidity Obligations, or release or compromise any obligation of any obligor with respect thereto; 

(iv) refrain from exercising any right or remedy, or delay in exercising any right or remedy, which it may have; or 

(v) take any other action which might discharge a subordinated party or a surety under applicable law; 

provided, however, that the taking of any such actions by any of the Trustees, the Liquidity Providers or the Subordination Agent shall not
prejudice the rights or adversely affect the obligations of any other party under this Agreement. 
 Section 9.10 Governing Law.

(c) To the extent that any Liquidity Provider or any of its properties has or may hereafter acquire any right of immunity, whether
characterized as sovereign immunity or otherwise, and whether under the United States Foreign Sovereign Immunities Act of 1976 (or any successor legislation) or otherwise, from any legal proceedings, whether in the United States or elsewhere, to
enforce or collect upon this Agreement, including, without limitation, immunity from suit or service of process, immunity from jurisdiction or judgment of any court or tribunal or execution of a judgment, or immunity of any of its property from
attachment prior to any entry of judgment, or from attachment in aid of execution upon a judgment, each of the Class A Liquidity Provider and the Class B Liquidity Provider, hereby irrevocably and expressly waives any such immunity, and agrees
not to assert any such right or claim in any such proceeding, whether in the United States or elsewhere.

other Person to invoke the process of any governmental authority for the purpose of commencing or sustaining a case (whether voluntary or not) against such Trust under any bankruptcy, insolvency or similar law or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of such Trust or any substantial part of its property or ordering the winding up or liquidation of the affairs of such Trust.
