(Spirit 2017-1 EETC)

connection with its duties hereunder and under the Deposit Agreement and shall be fully protected if any action taken, suffered or permitted by it in good faith is in accordance with the advice of counsel selected by it with due care;

Section 1.02. Instruction; Etc. The Underwriters, for and on behalf of each of the Investors, hereby irrevocably instruct the

 (X) immediately execute such Notice of Replacement Withdrawal as Escrow Agent and
transmit it to the Depositary by facsimile in accordance with the Deposit Agreement requesting a withdrawal, on the date specified in such notice, which shall not be less than five Business Days after such notice is given (the “Replacement

excluding the Replacement Withdrawal Date and (y) with respect to all Deposits, if any, previously withdrawn pursuant to the Applicable Notices of Purchase Withdrawal, all accrued and unpaid interest on such Deposits to but excluding the

(Y) direct the Depositary to transfer (i) the amounts requested to be withdrawn pursuant to clause (x) of the
immediately preceding paragraph, to the Replacement Depositary in accordance with the Replacement Deposit Agreement and (ii) the amounts requested to be withdrawn pursuant to clause (y) of the immediately preceding paragraph, to the
Paying Agent Account (as defined below); 
 (e) upon receipt of a Withdrawal Certificate executed by the Pass Through Trustee, together with

(Spirit 2017-1 EETC)









 (g) if there are any undrawn Deposits (as defined in the Deposit Agreement) on the
“Termination Date”, which shall mean the earlier of (i) the Outside Termination Date (as defined below) and (ii) the day on which the Escrow Agent receives notice from the Pass Through Trustee that the Pass
Through Trustee’s obligation to purchase Equipment Notes under the Note Purchase Agreement has terminated and the Cut-Off Date has occurred, to immediately give notice to the Depositary (with a copy to
the Paying Agent) substantially in the form of Exhibit B to the Deposit Agreement requesting a withdrawal of all of the remaining Deposits, together with accrued and unpaid interest on such Deposits to the date of withdrawal, on the 15th day after the date that such notice of withdrawal is given to the Depositary (or, if not a Business Day, on the next succeeding Business Day) (the “Final Withdrawal”);
provided that, if the day scheduled for the Final Withdrawal in accordance with the foregoing is within 10 days before or after a Regular Distribution Date, then the Escrow Agent shall request that such requested Final Withdrawal be made on
such Regular Distribution Date (the date of such requested withdrawal, the “Final Withdrawal Date”). If for any reason the Escrow Agent shall have failed to give the Final Withdrawal Notice to the Depositary on or before the Outside
Termination Date and there are unwithdrawn Deposits on such date, the Final Withdrawal Date shall be deemed to be the Outside Termination Date. The term “Outside Termination Date” shall mean January 31, 2019.  

Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts. The Escrow Agent hereby directs the Underwriters to, and the
Underwriters hereby acknowledge that on the date hereof they shall, irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount in U.S. dollars (“Dollars”) and immediately available funds equal to $247,099,000 for
deposit on behalf of the Escrow Agent with the Depositary in accordance with Section 2.1 of the Deposit Agreement. The Underwriters hereby instruct the Escrow Agent, upon receipt by the Depositary of such sum from the
Underwriters, to confirm such receipt by executing and delivering to the Pass Through Trustee an Escrow Receipt in the form of Exhibit A hereto (each, an “Escrow Receipt” and, collectively, the “Escrow
Receipts”) (a) to be affixed by the Pass Through Trustee to each Certificate and (b) to evidence the same percentage interest (the “Escrow Interest”) in the Account Amounts (as defined below) as the
Fractional Undivided Interest in the Pass Through Trust evidenced by the Certificate to which such Escrow Receipt is to be affixed. The Escrow Agent shall provide to the Pass Through Trustee for attachment to each Certificate newly issued under and
in accordance with the Pass Through Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from time to time request of the Escrow Agent. Each Escrow Receipt shall be registered by the Escrow Agent in a register (the
“Register”) maintained by the Escrow Agent in the name of the same holder that is the holder of the Certificate to which such Escrow Receipt is attached and may not thereafter be detached from such Certificate to which it is to be
affixed. No Escrow Receipt may be assigned or transferred except in connection with the assignment or transfer of the Certificate to which such Escrow Receipt is affixed. After the termination of the Deposit Agreement (or, if applicable, any
Replacement Deposit Agreement), no 

  

					
		 	5	 	 Escrow and Paying Agent Agreement (Class AA)

(Spirit 2017-1 EETC)









 
additional Escrow Receipts shall be issued and the Pass Through Trustee shall request the return to the Escrow Agent for cancellation of all outstanding Escrow Receipts. 

Section 1.04. Payments to Receiptholders. All payments and distributions made to a holder (each, a
“Receiptholder” and, collectively, the “Receiptholders”) of an Escrow Receipt in respect of such Escrow Receipt shall be made only from amounts deposited in the Paying Agent Account (as defined below) (the
“Account Amounts”). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will look solely to the Account Amounts for any payment or distribution due to such Receiptholder pursuant to the terms
of such Escrow Receipt and this Agreement (subject to Section 16 hereof) and (b) it will have no recourse to Spirit, the Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided
herein or in the Pass Through Trust Agreement. No Receiptholder shall have any right to vote or in any manner otherwise control the operation and management of the Paying Agent Account (as defined below) or the obligations of the parties hereto, nor
shall anything set forth herein, or contained in the terms of any Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association. 

Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt. If (a) any mutilated Escrow Receipt is surrendered
to the Escrow Agent or the Escrow Agent receives evidence to its satisfaction of the destruction, loss or theft of any Escrow Receipt and (b) there is delivered to the Escrow Agent and the Pass Through Trustee such security, indemnity or
bond, as may be required by them to hold each of them harmless, then, absent notice to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided that the
requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Escrow Agent shall execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts of like Escrow Interest in the Account Amounts and bearing a number not contemporaneously outstanding. 

In connection with the issuance of any new Escrow Receipt under this Section 1.05, the Escrow Agent may 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 Pass Through Trustee and the Escrow Agent) connected therewith. 

Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive evidence of the
appropriate Escrow Interest in the Account Amounts, as if originally issued, whether or not the lost, stolen or destroyed Escrow Receipt shall be found at any time. 

  

					
		 	6	 	 Escrow and Paying Agent Agreement (Class AA)

(Spirit 2017-1 EETC)









 The provisions of this Section 1.05 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 Escrow Receipts. 

Section 1.06. Additional Escrow Amounts. On the date of any Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in accordance with Section 2.4 of the Deposit Agreement. 

Section 1.07. Resignation or Removal of Escrow Agent. Subject to the appointment and acceptance of a successor Escrow Agent as
provided below, the Escrow Agent may resign at any time by giving 30 days’ prior written notice thereof to the Investors, but may not otherwise be removed except for cause by the written consent of the Investors with respect to Investors
representing Escrow Interests aggregating not less than a majority in interest in the Account Amounts (an “Action of Investors”). Upon any such resignation or removal, the Investors, by an Action of Investors, shall have the right
to appoint a successor Escrow Agent. If no successor Escrow Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Escrow Agent’s giving of notice of resignation or the removal of the
retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor Escrow Agent. Any successor Escrow Agent shall be a bank or trust company which has an office in the United States with a combined capital and surplus of at least
$75,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow Agent shall enter into such documents as the Pass Through Trustee shall require and shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be discharged from its duties and obligations hereunder. No resignation or removal of the Escrow Agent shall be
effective unless a written confirmation shall have been obtained from each of Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business, and Fitch Ratings, Inc. to the effect that the
replacement of the Escrow Agent with the successor Escrow Agent will not result in (a) a reduction of the rating for the Certificates below the then current rating for the Certificates or (b) a withdrawal or suspension of the
rating of the Certificates. 
 Section 1.08. Persons Deemed Owners. Prior to due presentment of a Certificate for registration
of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow Receipt for the purpose of receiving distributions pursuant to this
Agreement and for all other purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any notice to the contrary. 

Section 1.09. Further Assurances. Without limiting Sections 4 and 8 of this Agreement, the Escrow Agent agrees to
take such actions, and execute such other documents, as may be reasonably requested by the Pass Through Trustee in order to effectuate the purposes of this Agreement, the Note Purchase Agreement or the Deposit


  

					
		 	7	 	 Escrow and Paying Agent Agreement (Class AA)

(Spirit 2017-1 EETC)









 
Agreement and the performance by the Escrow Agent of its obligations hereunder or thereunder. 

SECTION 2. Paying Agent. 

Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby irrevocably appoints and authorizes the Paying Agent to act as
its paying agent hereunder, for the benefit of the Investors, for such specific purposes and with such powers as are specifically delegated to the Paying Agent by the terms of this Agreement, together with such other powers as are reasonably
incidental thereto. Any and all money received and held by the Paying Agent under this Agreement or the Deposit Agreement shall be held in the Paying Agent Account for the benefit of the Investors.    The Paying Agent (which term
as used in this sentence shall include reference to its affiliates and its own and its affiliates’ officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this
Agreement, and shall not by reason of this Agreement be a trustee for the Escrow Agent; (b) shall not be responsible for any recitals, statements, representations or warranties of any person other than itself contained in this Agreement
or for the failure by the Escrow Agent or any other person or entity (other than the Paying Agent) to perform any of its obligations hereunder (whether or not the Paying Agent shall have any knowledge thereof); (c) may consult with legal
counsel in connection with its duties hereunder and under the Deposit Agreement and shall be fully protected if any action taken, suffered or permitted by it in good faith is in accordance with the advice of counsel selected by it with due care;
(d) shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with
the handling of funds); and (e) shall in no event be liable for punitive, incidental or consequential damages. 

Section 2.02. Establishment of Paying Agent Account. Upon the execution of this Agreement, the Paying Agent shall establish and
maintain a segregated trust account (the “Paying Agent Account”) with the corporate trust department of Wilmington Trust, National Association in the name of the Escrow Agent, bearing a designation clearly indicating that the funds
deposited therein are held in trust for the benefit of the Escrow Agent. It is expressly understood by the parties hereto that the Paying Agent is acting as the paying agent and trustee of the Escrow Agent hereunder and that no amounts on deposit in
the Paying Agent Account constitute part of the Trust Property. The Paying Agent shall be under no obligation to invest any amounts held by it pursuant to the terms of this Agreement and the funds held in the Paying Agent Account shall not earn or
accrue interest. 
 Section 2.03. Payments from Paying Agent Account. The Escrow Agent hereby irrevocably instructs the Paying
Agent, and the Paying Agent agrees to act, as follows: 

  

					
		 	8	 	 Escrow and Paying Agent Agreement (Class AA)

(Spirit 2017-1 EETC)









 (a) On each Interest Payment Date (as defined in the Deposit Agreement) or as soon thereafter as
the Paying Agent has confirmed receipt in the Paying Agent Account from the Depositary of any amount in respect of accrued interest on the Deposits (other than as part of any Replacement Withdrawal, Event of Loss Withdrawal or Final Withdrawal), the
Paying Agent shall distribute out of the Paying Agent Account the entire amount deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record in the Register on the
15th day (whether or not a Business Day) preceding such Interest Payment Date by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder’s pro rata
share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount of interest deposited by the Depositary in the Paying Agent Account on such date, except that, with respect to Escrow Receipts registered on
the record date specified above in the name of a nominee of The Depository Trust Company (“DTC”), such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC. 

(b) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount in respect of any Final
Withdrawal or any Event of Loss Withdrawal or any Amortization Withdrawal, the Paying Agent shall forthwith (and, in the case of such Amortization Withdrawal, no later than August 15, 2018) distribute the entire amount of such Final Withdrawal
or such Event of Loss Withdrawal or such Amortization Withdrawal deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record on the 15th day (whether or not
a Business Day) preceding such Final Withdrawal Date or such Event of Loss Withdrawal or such Amortization Withdrawal by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder’s pro rata share (based on
the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount in the Paying Agent Account on account of such Final Withdrawal or such Event of Loss Withdrawal or such Amortization Withdrawal, except that, with respect to
Escrow Receipts registered on the record date specified above in the name of a nominee of DTC, such distribution shall be made by wire transfer in immediately available funds to the account designated by DTC. 

(c) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account from the Depositary of any amount referred to in clause
(y) of Section 1.02(d)(X) in respect of the Replacement Withdrawal, on the immediately succeeding Interest Payment Date, the Paying Agent shall distribute out of the Paying Agent Account the entire such amount
deposited therein by the Depositary. There shall be so distributed to each Receiptholder of record in the Register on the 15th day (whether or not a Business Day) preceding such Interest Payment
Date by check mailed to such Receiptholder, at the address appearing in the Register, such Receiptholder’s pro rata share (based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the total amount of interest deposited
by the Depositary in the Paying Agent Account

(Spirit 2017-1 EETC)









 
on such date, except that, with respect to Escrow Receipts registered on the record date specified above in the name of a nominee of DTC, such distribution shall be made by wire transfer in
immediately available funds to the account designated by DTC. 
 (d) If any payment of interest referred to in
Section 2.03(a) or of interest or principal in respect of any Final Withdrawal or any Replacement Withdrawal or any Event of Loss Withdrawal or of principal in respect of any Amortization Withdrawal is not received by the
Paying Agent within five days of the applicable date when due, then it shall be distributed to Receiptholders after actual receipt by the Paying Agent on the same basis as a Special Payment (as defined in the Pass Through Trust Agreement) is
distributed under the Pass Through Trust Agreement. 
 (e) The Paying Agent shall include with any check mailed pursuant to this
Section 2.03 any notice required to be distributed under the Pass Through Trust Agreement that is furnished to the Paying Agent by the Pass Through Trustee. 

Section 2.04. Withholding Taxes. The Paying Agent shall exclude and withhold from each distribution of accrued interest on the
Deposits (as defined in the Deposit Agreement) and any amount in respect of any Final Withdrawal and any Event of Loss Withdrawal and any Amortization Withdrawal and any amounts referred to in clause (y) of Section 1.02(d)(X) in respect of
the Replacement Withdrawal (which exclusion and withholding shall constitute payment of such amounts payable hereunder or in respect of Deposit, as applicable) any and all withholding taxes applicable thereto as required by law. The Paying Agent
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 Deposits (as defined in the Deposit
