amended, modified or supplemented from time to time in accordance with the terms thereof, the “Escrow and Paying Agent Agreement”); 

WHEREAS, the Underwriters and the Pass Through Trustee intend that the Net Proceeds be held in escrow by the Escrow Agent on behalf of the

 WHEREAS, the Escrow Agent wishes to appoint
Citibank, N.A. as Depositary pursuant to this Agreement and Citibank, N.A. is willing to accept such appointment upon the terms and conditions of this Agreement. 

NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 SECTION 1. Appointment and Acceptance of
Depositary; Establishment of Accounts. 
 Section 1.1. Appointment and Acceptance of Depositary. The Escrow Agent hereby
appoints the Depositary, effective as of the date hereof, to have all rights, powers and duties set forth herein on the part of the Depositary. The Depositary hereby agrees to act as depositary bank as provided herein and in connection therewith to
accept all amounts to be delivered to or held by the Depositary pursuant to the terms of this Agreement. The Depositary further agrees to hold, maintain and safeguard the Deposits and the Accounts (as defined below) during the term of this Agreement
in accordance with the provisions of this Agreement. The Escrow Agent shall not have any right to withdraw, assign or otherwise transfer moneys held in the Accounts except as permitted by this Agreement. 

Section 1.2. Establishment of Accounts. The Escrow Agent hereby instructs the Depositary, and the Depositary agrees, to establish
the separate deposit accounts in respect of each of the Aircraft listed on Schedule I hereto and to establish such additional separate deposit accounts as may be required in connection with the deposits contemplated by
Section 2.4 hereof (each, an “Account” and collectively, the “Accounts”), each in the name of the Escrow Agent and all on the terms and conditions set forth in this Agreement. The
Depositary shall establish and maintain all Accounts at the office of the Depositary located at 480 Washington Blvd, 18th Floor, Jersey City, NJ 07310, or at such address within the United States as the Depositary may designate from time to time by

 SECTION 2. Deposit Mechanics. 

  

					
		  	2	  	 Deposit Agreement (Class A)

(Spirit 2017-1 EETC)









 Section 2.1. Deposits. The Escrow Agent shall direct the Underwriters to deposit with
the Depositary on the date of this Agreement (the “Deposit Date”) in Federal (same day) funds by wire transfer to: CITIBANK, N.A., ABA:
[                ]; Account Name: Escrow Concentration Account; A/C#.:
[                ]: Reference: Spirit 2017-1A INITIAL DEPOSIT ACCOUNT, and the Depositary shall accept from the Underwriters, on
behalf of the Escrow Agent, the sum of US$82,366,000. Upon acceptance of such sum, the Depositary shall (i) establish each of the deposits specified in Schedule I hereto maturing in accordance with this Agreement and
(ii) credit each such deposit to the related Account as set forth herein. Each deposit described in the preceding sentence and each re-deposit described in the next succeeding sentence is referred
to individually as a “Deposit” and such deposits and re-deposits are referred to collectively as the “Deposits.” Upon receipt of any
re-deposit pursuant to Section 2.4 hereof, the Depositary shall establish a separate Account for each re-deposit maturing in accordance with this Agreement. No
amount shall be deposited in any Account other than the related Deposit, in the case of the amounts and Accounts specified in Schedule I, or the applicable re-deposit, in the case of Accounts established
pursuant to the preceding sentence. 
 Section 2.2. Interest. Each Deposit shall bear interest on the unwithdrawn amount thereof
from and including the date of deposit to but excluding the date of withdrawal (it being understood that the date of withdrawal in the case of any payment by the Depositary of the amount of the Final Withdrawal (as defined below) on the Outside
Termination Date (as defined below) shall be deemed to be the date of such payment) at the rate of 3.650% per annum (computed on the basis of a 360-day year of twelve
30-day months) payable to the Paying Agent on behalf of the Escrow Agent in arrears on each Interest Payment Date (as defined below), on the date of any Final Withdrawal, on the date of any Replacement
Withdrawal (as defined below) or on the date of any Event of Loss Withdrawal (as defined below), as applicable, all in accordance with the terms of this Agreement. As used in this Agreement, the term “Interest Payment Date”, with
respect to each Deposit that, as of any date of determination, has not been withdrawn pursuant to a Final Withdrawal, a Replacement Withdrawal or an Event of Loss Withdrawal shall mean each of February 15 and August 15 commencing on
August 15, 2018 and ending on the earlier of the February 15 and August 15 immediately following the date on which such Deposit is withdrawn pursuant to a Notice of Purchase Withdrawal (as defined below); provided that interest
accrued on any Deposit that is withdrawn pursuant to a Notice of Purchase Withdrawal shall be paid on the next Interest Payment Date following the related Purchase Withdrawal, notwithstanding any intervening Final Withdrawal or Event of Loss
Withdrawal or Amortization Withdrawal with respect to any other Deposit and notwithstanding the fact that the relevant Account may have been closed before such Interest Payment Date, but, if any intervening Replacement Withdrawal occurs before such
next Interest Payment Date, such accrued interest shall, instead, be paid on the date of such Replacement Withdrawal. For the avoidance of doubt, no interest shall accrue on any Deposit from the date of withdrawal pursuant to a Notice of Purchase
Withdrawal until the next Interest Payment Date or, if earlier, the date of a Replacement Withdrawal. All interest paid pursuant to this Agreement shall be non-compounding. 

Section 2.3. Withdrawals.

 (a) Purchase Withdrawal. The Escrow Agent may, by providing at least three Business
Days’ prior notice of withdrawal to the Depositary (or such shorter period as agreed by the Depositary) in the form of Exhibit A hereto (a “Notice of Purchase Withdrawal”), withdraw the entire balance of any Deposit (but
not any accrued and unpaid interest thereon) (with respect to any Deposit, such withdrawal, the “Purchase Withdrawal”), except that at any time prior to the actual withdrawal of such Deposit, the Escrow Agent or the Pass Through
Trustee may, by notice to the Depositary, which notice has been actually received by the Depositary prior to such actual withdrawal, cancel such withdrawal (including on the scheduled date therefor), and thereafter such Deposit shall continue to be
maintained by the Depositary in accordance with the original terms thereof. Following the Purchase Withdrawal of any Deposit, the balance in the related Account shall be reduced to zero and the Depositary shall close such Account. As used in this
Agreement, “Business Day” shall mean any day, other than a Saturday, Sunday or other day on which commercial banks are authorized or required by law to close in New York, New York, Miramar, Florida, or Wilmington, Delaware. 

(b) Final Withdrawal; Replacement Withdrawal; Event of Loss Withdrawal; Amortization Withdrawal. 

(i) The Escrow Agent may, by providing at least 15 days’ prior notice of withdrawal to the Depositary in the form of Exhibit B
hereto (a “Notice of Final Withdrawal”), withdraw (x) the entire amount of all of the remaining Deposits together with (y) all accrued and unpaid interest on such Deposits (excluding the accrued and unpaid
interest on each Deposit previously withdrawn pursuant to a Notice of Purchase Withdrawal) to but excluding the specified date of such withdrawal (such withdrawal of the amounts set forth in the immediately preceding clauses (x) and (y), the
“Final Withdrawal”), on such date as shall be specified in such Notice of Final Withdrawal. If a Notice of Final Withdrawal has not been given to the Depositary on or before the Outside Termination Date (as defined below) and there
are unwithdrawn Deposits on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on the Outside Termination Date. Following the Final Withdrawal of any Deposit, the balance in the related Account shall be
reduced to zero and the Depositary shall close such Account. As used in this Agreement, the term “Outside Termination Date” shall mean January 31, 2019. 

(ii) The Escrow Agent may, by providing at least five Business Days’ prior notice of withdrawal to the Depositary in the form of
Exhibit C hereto (a “Notice of Replacement Withdrawal”), withdraw (x) with respect to all Deposits then held by the Depositary, (1) the entire amount of such Deposits together with (2) all
accrued and unpaid interest on such Deposits to but excluding the specified date of such Replacement Withdrawal (as defined below) and (y) with respect to all Deposits, if any, previously withdrawn pursuant to a Notice of Purchase

 (iii) The Escrow Agent may, by providing at least 15 days’ prior notice of withdrawal to
the Depositary in the form of Exhibit D hereto (a “Notice of Event of Loss Withdrawal”) in respect of a Deposit, withdraw (x) the entire balance of such Deposit together with (y) all accrued and unpaid
interest on such Deposit to but excluding the specified date of such withdrawal (with respect to any Deposit, such withdrawal of the amounts set forth in the immediately preceding clauses (x) and (y), the “Event of Loss
Withdrawal”), on such date as shall be specified in such Notice of Event of Loss Withdrawal. Following such Event of Loss Withdrawal, the balance in the related Account shall be reduced to zero and the Depositary shall close such Account.

 (iv) With respect to any Early Delivery Aircraft, if a Notice of Purchase Withdrawal for such Early Delivery Aircraft has not been
delivered by the Escrow Agent or, if such Notice has been delivered but the financing for such Early Delivery Aircraft in accordance with the Note Purchase Agreement has not occurred, in each case, before August 15, 2018, the Depositary shall
release from the Account for such Early Delivery Aircraft an amount of Deposits equal to the principal amortization installment scheduled for payment on August 15, 2018 for such Early Delivery Aircraft as set forth in Schedule I hereto (such
withdrawal of such amount for such Early Delivery Aircraft, the “Amortization Withdrawal”), and the Depositary shall pay the amount of Amortization Withdrawal for such Early Delivery Aircraft to the Paying Agent on August 15,
2018. Following such Amortization Withdrawal, the balance of the Deposits in the Account for such Early Delivery Aircraft shall continue to be maintained by the Depositary in accordance with the original terms thereof and may be withdrawn in
accordance with a Notice of Purchase Withdrawal, Final Withdrawal or Replacement Withdrawal, as the case may be. 
 (c) Compliance with
Withdrawal Notices. If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Final Withdrawal, Notice of Replacement Withdrawal or Notice of Event of Loss Withdrawal (each, a “Withdrawal Notice”)
complying with the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the Depositary
be required, pursuant to any Withdrawal Notice or otherwise, to make payments hereunder on or in respect of any Deposit in excess of the amount of such Deposit together with accrued interest thereon as provided in this Agreement. 

Section 2.4. Other Accounts. On the date of Purchase Withdrawal of any Deposit, the Escrow Agent, or the Pass Through Trustee on
behalf of the Escrow Agent, shall re-deposit with the Depositary any portion thereof not used to acquire Equipment Notes and the Depositary shall accept the same for deposit hereunder. Any sums so received for
deposit shall be established as a new Deposit and credited to a new Account, all as more fully provided in Section 2.1 hereof, and thereafter the provisions of this Agreement shall apply thereto as fully and with the same
force and effect as if such Deposit had been established on the Deposit Date. 
 SECTION 3. Termination. This Agreement shall
terminate on the fifth Business Day after the later of the date on which (i) all of the Deposits shall have been withdrawn and paid as provided herein without any re-deposit and
(ii) all accrued and unpaid interest on the 

  

					
		  	5	  	 Deposit Agreement (Class A)

(Spirit 2017-1 EETC)









 
Deposits shall have been paid as provided herein, but in no event prior to the date on which the Depositary shall have performed in full its obligations hereunder. 

SECTION 4. Payments. All payments made by the Depositary hereunder shall be paid in United States Dollars and immediately available
funds by wire transfer (i) in the cases of (v) accrued and unpaid interest on the Deposits payable under Section 2.2 hereof, (w) any Final Withdrawal, (x) any Event of Loss
Withdrawal, (y) Amortization Withdrawal or (z) accrued and unpaid interest on all Deposits, if any, previously withdrawn pursuant to a Notice of Purchase Withdrawal, which interest is payable pursuant to a Notice of
Replacement Withdrawal, directly to the Paying Agent at Wilmington Trust, National Association, Wilmington, Delaware, ABA # [                    ],
Corporate Trust, Account No. [                    ], Reference: Spirit Airlines 2017-1A EETC, Attn:
Jacqueline Solone, or to such other account as the Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent, (ii) in the case of any withdrawal of one or more Deposits pursuant to a Notice of Purchase
Withdrawal, directly to or as directed by the Escrow Agent as specified and in the manner provided in such Notice of Purchase Withdrawal, and (iii) in the case of any withdrawal of one or more Deposits then held by the Depositary
together with accrued and unpaid interest on such Deposits pursuant to a Notice of Replacement Withdrawal, as directed by the Escrow Agent as specified and in the manner provided in such Notice of Replacement Withdrawal. The Depositary hereby waives
any and all rights of set-off, combination of accounts, right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against the Deposits howsoever arising. To
the extent permitted by applicable law, all payments on or in respect of each Deposit shall be made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges (collectively,
“Taxes”). However, if the Depositary shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder, the Depositary shall (i) make such deduction or withholding and
(ii) pay the full amount deducted or withheld (including in respect of additional amounts described below) to the competent taxation authority. If any Taxes imposed by the nation or jurisdiction under which the Depositary is formed or
organized (other than the United States), or any political subdivision thereof (other than pursuant to FATCA), are required to be deducted or withheld by the Depositary or the Paying Agent (pursuant to Section 2.04 of the Escrow and Paying
Agent Agreement) in respect of any sum payable hereunder, the Depositary shall pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow and
Paying Agent Agreement after such deduction or withholding equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on any Deposit would otherwise fall on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day, and no additional interest shall accrue in respect of such extension. For purposes of this Section 4, “FATCA” means
Section 1471 through 1474 of the Internal Revenue Code of 1986 (as amended, the “Code”), any current or future regulations or official interpretations thereof or thereunder, any agreements entered into pursuant to
Section 1471(b) of the Code, any intergovernmental agreements entered into in connection with any of the foregoing and any fiscal or regulatory legislation, rules or practices adopted pursuant to any such intergovernmental agreement.

documents, as amended, or bylaws, as amended, of it or any similar instrument binding on it or any order, writ, injunction or decree of any court or governmental authority against it or by which it or any of its properties is bound or of any

with respect to any order of any court, governmental authority, arbitration board or administrative agency so as to adversely affect its ability to perform its obligations under this Agreement.

the need for any other action of any person, including the Escrow Agent or any other Receiptholder) (i) to proceed directly against the Depositary by making a demand to the Depositary for the portion of such payment that would have been
distributed to such Receiptholder pursuant to the Escrow and Payment Agent Agreement or by bringing suit to enforce payment of such portion and (ii) to enforce any other rights that the Escrow Agent may have in respect of amounts due from the
Depositary under this Agreement that would have been distributed to such Receiptholder pursuant to the Escrow and Paying Agent Agreement, and that any such claim shall not be subject to defenses that the Depositary may have against the Escrow Agent.
As used in this Agreement, the term “Receiptholder” shall have the meaning assigned to such term in the Escrow and Paying Agent Agreement. 

SECTION 16. Miscellaneous. (a) The Depositary shall have only those duties as are specifically and expressly provided herein with
respect to it and no other duties shall be implied. The Depositary shall have no duty to solicit any payments, including, without limitation, the Deposits. 

(b) The Depositary shall be entitled to rely upon any instruction, notice, request or other instrument delivered to it hereunder by the Escrow
Agent or the Pass Through Trustee without being required to determine the authenticity or validity thereof, or the truth or accuracy of any information stated therein. The Depositary may act in reliance upon any signature believed by it to be
genuine and may assume that any person purporting to make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so. 

(c) The Depositary (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates’
officers, directors, employees and agents); (i) shall have no duties or responsibilities under this Agreement except those expressly set forth in this Agreement; (ii) 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 Depositary) to perform any of its obligations hereunder (whether or not the Depositary
shall have any knowledge thereof); (iii) may consult with legal counsel or accountants in connection with its duties hereunder and shall be fully protected if any action taken, suffered, omitted to be taken or permitted by it in good faith is
in accordance with the advice of counsel and accountants selected by it with due care; and (iv) shall not be responsible for any action taken, suffered 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, in each case, as finally adjudicated in a court of competent jurisdiction). In the event of any
conflict or inconsistency between any provision in this Agreement and a provision in any other document with respect to the subject matter of this Agreement, the provisions of this Agreement shall control. 

(d) If any portion of the Deposit is at any time attached, garnished or levied upon under any court order, or enjoined or stayed by any court
order, or in case of any order, judgment or decree shall be made or entered by any court affecting the Deposits or any part thereof, then and in any such event, the Depositary is authorized to rely upon and comply with any such order, writ, judgment
or decree which it is advised in writing by external legal counsel of national reputation is binding upon it without the need for appeal or other action; and if the Depositary complies with such order, writ, judgment or decree, it shall not be
liable to the Escrow Agent or any Receiptholder commencing action pursuant to Section 15 even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated so long as such order, writ,
judgment or decree was not made, issued or entered for any reason that a final adjudication of a court of competent jurisdiction determines was based on the Depositary’s willful misconduct or gross negligence (or simple negligence in connection
with the handling of funds). 
 (e) The Escrow 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); (i) shall have no duties or responsibilities under this Agreement except those expressly set forth in this Agreement; (ii) shall not be responsible to the Depositary
for any recitals, statements, representations or warranties of any person other than itself contained in this Agreement or the Escrow and Paying Agent Agreement or for the failure by the Depositary or any other person or entity (other than the
Escrow Agent) to perform any of its obligations hereunder (whether or not the Escrow Agent shall have any knowledge thereof); (iii) may consult with legal counsel in connection with its duties hereunder and under the Escrow and Paying Agent
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; and (iv) 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). 

(f) (i) Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism
Act of 2001 (“USA PATRIOT Act”) requires the Depositary to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Escrow Agent acknowledges that Section 326 of
the USA PATRIOT Act and the Depositary’s identity verification procedures require the Depositary to obtain information which may be used to confirm the Escrow Agent’s identity including without limitation name, address and organizational
documents (“identifying information”). The Escrow Agent agrees to provide the Depositary with and consent to the Depositary obtaining from third parties any such identifying information required as a condition of opening an account

of Treasury’s Office of Foreign Assets Control (“OFAC”), and other applicable U.S. anti-money laundering laws and regulations (collectively, the “anti-money laundering/OFAC laws”), or (y) to meet the
requirements of the Escrow Agent’s internal know your customer policies and procedures adopted in accordance with the anti-money laundering/OFAC laws. 

(g) To the extent that the Depositary 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, the Depositary 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. 
 (h) If any provision of this Agreement is determined to be prohibited or unenforceable by reason of any applicable
law of a jurisdiction, then, to the extent permitted by applicable law, such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and
any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction. 

SECTION 17. Limitation on Damages. In no event shall the Depositary be responsible or liable for special, indirect, punitive, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit, whether or not foreseeable) suffered by the Escrow Agent or any of the Receiptholders in connection with this Agreement or the transactions
contemplated or any relationships established by this Agreement irrespective of whether the Depositary has been advised of the likelihood of such loss or damage and regardless of the form of action.

earned by the Deposits will, to the greatest extent permitted by applicable law, be prepared and filed by the Escrow Agent with the IRS and any other taxing authority as required by law. 

(b) The Escrow Agent acknowledges and agrees that the Depositary shall have no responsibility for the preparation and/or filing of any U.S.
federal, state or local income, franchise or other tax return with respect to the Deposits or any income earned by the Deposits other than any such responsibility that cannot be assigned to, or assumed by the Escrow Agent under applicable law.

Agreement or the resignation or removal of the Depositary or the Escrow Agent, as the case may be.
