NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: 1. CERTAIN DEFINITIONS 1.1 Except as otherwise defined in this Agreement, including its annexes, schedules and exhibits, terms used herein in capitalized form shall have the meanings attributed thereto in Annex A. 1.2 Unless the context otherwise requires, any reference herein to any of the Operative Documents refers to such document as it may be modified, amended or supplemented from time to time in accordance with its terms and the terms of each other agreement restricting the modification, amendment or supplement thereof. 1.3 The Facility Agent does not warrant or accept responsibility for, and shall not have any liability with respect to (a) the continuation of, administration of, submission of, calculation of or any other matter related to ABR, the Term SOFR Reference Rate, Term SOFR or Term SOFR, or any component definition thereof or rates referred to in the definition thereof, or any alternative, successor or replacement rate thereto (including any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement) will be similar to, or produce the same value or economic equivalence of, or have the same volume or liquidity as, ABR, the Term SOFR Reference Rate, Term SOFR, Term SOFR or any other Benchmark prior to its discontinuance or unavailability, or (b) the effect, implementation or composition of any Conforming Changes. The Facility Agent and its affiliates or other related entities may engage in transactions that affect the calculation of ABR, the Term SOFR Reference Rate, Term SOFR, Term SOFR, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower. The Facility Agent may select information sources or services in its reasonable discretion to ascertain ABR, the Term SOFR Reference Rate, Term SOFR, Term SOFR or any other Benchmark, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, 24006693130-v4 - 3 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service. 2. COMMITMENTS; BORROWER'S NOTICE OF PAYMENT DATES; CLOSING PROCEDURE 2.1 Subject to the terms and conditions of this Agreement, each Lender agrees to make a secured loan to the Borrower in respect of each Advance (herein called, for such Advance, a "Loan") on a Borrowing Date to be designated pursuant to Clause 2.3, but in no event later than the Commitment Termination Date. Except as provided in Clauses 5.13 and 5.14, each Loan shall be a SOFR Loan; provided that any Loan that is deemed to be an ABR Loan as provided herein shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin. In the case of each Lender on any Borrowing Date, the Loan shall, in respect of each Aircraft, be equal to the least of: (a) such Lender's Participation Percentage multiplied by, on any Borrowing Date, the relevant Financed Amount; and (b) such Lender's Maximum Commitment minus the aggregate amount of all Loans made by such Lender prior to such Borrowing Date that remain outstanding on such Borrowing Date (such amount, with respect to such Lender on such Borrowing Date, its "Commitment"). 2.2 If any Lender shall default in its obligation to make the amount of its Commitment available pursuant to Clause 2.1, [***]. Without limiting the above, if the Facility Agent disburses a Lender's Commitment without first having received funds from a defaulting Lender, then such defaulting Lender hereby agrees to indemnify the Facility Agent against any loss it may incur as a result of such failure to fund by such defaulting Lender. 2.3 As more particularly specified in Clause 5.2, the Borrower shall execute and deliver to each Lender with appropriate insertions a Loan Certificate to evidence such Lender's Maximum Commitment. The Loan Certificates shall be issued such that each Lender receives a Loan Certificate. Each Loan shall be evidenced by this Agreement, the Loan Certificate with respect thereto, and notations made from time to time by each Lender in its books and records, including computer records. Each Lender shall record in its books and records, including computer records, the principal amount of the Loans owing to it from time to time. Absent evidence to the contrary, each Lender's books and records shall constitute presumptive evidence of the accuracy of the information contained therein. Failure by any Lender to make any such notation or record shall not affect the obligations of the Borrower to such Lender with respect to the repayment of its Loans. (a) Each Party hereby acknowledges that (i) prior to the Effective Date certain Lenders have made Loans in respect of certain Advances relating to certain Existing Aircraft which were paid by or on behalf of the Borrower on certain dates prior to the Effective Date in the amounts as set out in the column entitled Financed Amount in the table set out in Schedule III, (ii) the proceeds of such Loans were paid to the 24006693130-v4 - 4 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] Borrower or to its direction and (iii) the terms of this Agreement and the other Operative Documents shall continue to apply to such Loans. (b) The Borrower agrees to give the Facility Agent at least [***] prior written notice (the "Funding Notice") of each Borrowing Date in respect of any Loans, such notice to be received by the Facility Agent prior to [***], and which shall be in substantially the form of Exhibit A. On the Initial Borrowing Date, the Lenders shall make Loans (subject to the limitations specified in Clause 2.1) in respect of certain Advances relating to certain Additional Aircraft which were paid by or on behalf of the Borrower prior to the Initial Borrowing Date in the amounts equal to the applicable Financed Amounts. The proceeds of such Loans shall be paid to the Borrower; provided, however, that the Borrower shall have paid all Advances relating to any Additional Aircraft that were due and payable prior to the Initial Borrowing Date, and the Borrower shall remain responsible for the Advances in an amount equal to the Equity Contributions applicable as of the Initial Borrowing Date for each Aircraft (including the Existing Aircraft and the Additional Aircraft). (c) In the event that any Loan shall not be consummated in accordance with the terms hereof on the Effective Date or the Borrowing Date specified in a Funding Notice, the Lenders and the Borrower shall cooperate with each other to arrange a mutually acceptable postponement of such date (the "Delayed Borrowing Date"). [***]. Notwithstanding anything to the contrary herein, in the event that any amount paid by or on behalf of the Borrower on any Borrowing Date with respect to a pre-delivery payment obligation for any Aircraft exceeds the required Equity Contribution set forth on Schedule III for such Aircraft on such Borrowing Date as a result of any portion of the Financed Amount for such Aircraft not being available on such Borrowing Date as a result of a PDP Funding Date Deficiency, Lender agrees to refund to the Borrower the amount of such excess either by netting such excess amount against a future Equity Contribution or Loan payment obligation of the Borrower or by directly funding such amount as an additional Loan to the Borrower, in each case, as soon as reasonably practicable after such PDP Funding Date Deficiency ceases to exist. The Lender shall have the right in its sole discretion to choose whether to fund such excess amount as an additional Loan or to net such excess amount against the Borrower's future payment obligations hereunder. 2.4 On the Initial Borrowing Date, each Lender, through or on behalf of the Facility Agent, agrees to pay the amount of its Commitment for the Loans in respect of the initial Advances under this Ninth Amended and Restated Agreement to such account as the Borrower shall direct the Facility Agent in writing to reimburse Borrower for a portion of previously funded Purchase Price Installments relating to Additional Aircraft. On each other Borrowing Date for each subsequent Loan specified in a Borrower's notice referred to in Clause 2.3, subject to the terms and conditions of this Agreement, each Lender, through or on behalf of the Facility Agent, agrees to pay the amount of its Commitment for the Loan in respect of each such Advance directly to Airbus by wiring such amounts to the account or accounts specified in the applicable Funding Notice. The Borrower agrees that the actual transfer of the proceeds of Loans to the bank designated by the Borrower for credit to 24006693130-v4 - 5 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] Airbus's or the Borrower's account (as applicable) shall constitute conclusive evidence that the Loans were made. 3. FEES; CANCELLATION OF FACILITY AMOUNT 3.1 Each Loan Certificate shall bear interest and be repaid in accordance with the applicable terms of this Agreement and the Mortgage. 3.2 The Borrower shall pay to the Facility Agent for the account of each Lender, the fees set forth in the relevant Fee Letter. 3.3 The Borrower shall pay to the Facility Agent for the account of each Lender, the Commitment Fee quarterly in arrears, based on the daily average of the undrawn portion of the Facility Amount during such period, as the Facility Amount may be cancelled or reduced under Clause 3.5 on every Interest Payment Date following the Effective Date calculated daily on the basis of a year of 360 days and the actual number of days elapsed. 3.4 The Borrower paid to the Facility Agent for the account of the Facility Agent, an amount equal to [***] on the Original Signing Date, and shall pay an amount equal to [***] to the Facility Agent on each anniversary of the Original Signing Date until the date on which the Security Trustee releases the Collateral from the Lien of the Mortgage in accordance with Clause 7.1 of the Mortgage. 3.5 The Borrower may at any time permanently and irrevocably cancel or reduce the Facility Amount (in whole or in part) provided that the amount thereof shall be specified in a written notice to the Facility Agent from the Borrower and countersigned by the Guarantors [***] before the effective date of such cancellation and the undrawn portion of the Facility Amount may not be cancelled or reduced to the extent that the undrawn portion of the Facility will be required to be drawn in the future to make future Advances in respect of an Aircraft with respect to which a Loan is outstanding. 4.

(c) If any sum payable under the Loan Certificates or under the Mortgage falls due on a day which is not a Business Day, then such sum shall be payable on the next succeeding Business Day. (d) The principal of the Loans relating to an Aircraft shall be due and payable in full upon the first to occur of (i) the Delivery Date of such Aircraft, as notified by the Borrower to the Facility Agent [***] prior to such day, (ii) except as specified in clause (iii), the date falling [***] after the final day of the Scheduled Delivery Month for such Aircraft, (iii) in the event of a Relevant Delay, the date falling [***] after the final day of the Scheduled Delivery Month of such Aircraft, and (iv) the Termination Date. The Borrower shall notify the Facility Agent and the Lenders of the expected Delivery Date of each Aircraft, not less than [***] prior to the Interest Payment Date immediately preceding such expected Delivery Date. Upon receipt of such notice, the Lenders shall effect a stub Interest Period ending on such expected Delivery Date for the Loans allocable to such Aircraft. If a Delivery Date is delayed, then the Facility Agent and the Lenders shall continue to make funds available in accordance with the terms hereof, at the Term SOFR rate plus the Applicable Margin until the earlier of (x) the actual Delivery Date of such Aircraft (y) the date falling [***] after the final day of the Scheduled Delivery Month of such Aircraft and (z) in the event of a Relevant Delay, the date falling [***] after 24006693130-v4 - 12 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] the last day of the Scheduled Delivery Month specified for such Aircraft in Schedule III. (e) Each Loan Certificate shall bear interest at the Past Due Rate on any principal thereof and, to the extent permitted by Applicable Law, interest (other than interest accrued at the Past Due Rate) and other amounts due thereunder and hereunder, not paid when due (whether at stated maturity, by acceleration or otherwise), for any period during which the same shall be overdue, payable on demand by the Lender given through the Facility Agent. (f) The Loan Certificates shall be executed on behalf of the Borrower by one of its authorized officers. Loan Certificates bearing the signatures of individuals who were at any time the proper officers of the Borrower shall bind the Borrower, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the delivery of such Loan Certificates or did not hold such offices at the respective dates of such Loan Certificates. No Loan Certificates shall be issued hereunder except those provided for in Clause 5.2(a) and any Loan Certificates issued in exchange or replacement therefor pursuant to the terms of this Agreement. (g) Upon the request of the Borrower, the Lenders shall have the right in their sole discretion to extend the Commitment Termination Date by one year to the next Extension Date by delivering an Extension Notice to the Borrower no later than [***] prior to the then-current Commitment Termination Date. Any such extension shall require the unanimous consent of all Lenders, each acting at their own discretion. 5.3 Taxes (a) Any and all payments by or on account of any obligation of the Borrower hereunder to the Lenders, the Facility Agent or the Security Trustee, under the Loan Certificates and each other Operative Document shall be made free and clear of and without deduction for any Taxes, except as required by Applicable Law; provided that if the Borrower shall be required to deduct any Indemnified Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Clause 5.3) the Security Trustee, the Facility Agent and each Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall, or shall cause the Security Trustee to, make such deductions and (iii) the Borrower shall, or shall cause the Security Trustee to, pay the full amount deducted to the relevant Governmental Entity in accordance with Applicable Law. (b) In addition, the Borrower shall, or shall cause the Security Trustee to, pay any Indemnified Taxes or Taxes addressed in Clause 5.3(j) to the relevant Governmental Entity in accordance with Applicable Law and shall indemnify the Security Trustee, the Facility Agent and each Lender on an After-Tax Basis within 24006693130-v4 - 13 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] [***] after written demand therefor, for the full amount of any Indemnified Taxes paid by the Security Trustee, the Facility Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder or under the other Operative Documents (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Clause) and, other than any of the following to the extent (but only to the extent) resulting from the gross negligence or willful misconduct of the Security Trustee, the Facility Agent or such Lender, any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes are correctly or legally imposed or asserted by the relevant Governmental Entity. Determinations and calculations made by a Lender with respect to an indemnity due hereunder shall be conclusive absent manifest error, provided that such determinations and calculations are made on a reasonable basis. (c) As soon as practicable after any payment of Taxes by the Borrower to a Governmental Entity, the Borrower shall, or shall cause the Security Trustee to, deliver to the Facility Agent the original or a certified copy of a receipt issued by such Governmental Entity evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Facility Agent. (d) Any Person that at any time is entitled to an exemption from or reduction of any Indemnified Tax, at the request of the Borrower or the Security Trustee, shall deliver to it (with a copy to the Facility Agent) such properly completed and executed documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Security Trustee as will permit the utilization of such exemption or reduction, provided that such Person has determined in its reasonable good faith judgment that to do so will not result in any adverse consequences to such Person, unless the adverse consequence can be cured through an indemnity (such determination to be made by such Person in its reasonable good faith judgment), and such Person is indemnified for any adverse consequence by the Borrower in a manner reasonably satisfactory to such Person. (e) If the Borrower becomes obligated to pay any Indemnified Taxes pursuant to this Clause 5.3, each applicable Lender and the Facility Agent hereby agrees to cooperate with the Borrower, as described in Clauses 5.11(d). (f) (i) If the Security Trustee, the Facility Agent or a Lender receives a refund of any Taxes in respect of which additional amounts were paid by the Borrower pursuant to this Clause 5.3, the Security Trustee, the Facility Agent or such Lender shall, as soon as reasonably practicable, pay to the Borrower the amount of such refund plus any interest received on such refund fairly attributable to such Tax and not in excess of amounts previously paid by the Borrower to the Security Trustee, the Facility Agent or such Lender pursuant to this Clause 5.3 (other than interest actually received on such refund and fairly attributable to such Tax), provided, however, that such amount shall be reduced by the amount of any obligation of the Borrower under this Agreement then due and not made (and the amount of such reduction

24006693130-v4 - 14 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] shall not be payable before such time and to the extent as such obligation shall have been satisfied). The Security Trustee, the Facility Agent and each Lender shall in good faith use diligence in filing its tax returns and in dealing with taxing authorities to seek and claim any such refund and to minimize the Taxes payable or indemnifiable by the Borrower hereunder if it can do so, in its sole opinion, without adverse consequences. If the Facility Agent or a Lender actually utilizes any credit with respect to any Taxes in respect of which additional amounts were paid by the Borrower pursuant to this Clause 5.3, the Security Trustee, the Facility Agent or such Lender shall pay to the Borrower an amount equal to the amount of such credit, but not in excess of amounts previously paid by the Borrower to the Security Trustee, the Facility Agent or such Lender, provided, however, that such amount shall be reduced by the amount of any obligation of the Borrower under this Agreement then due and not made (and the amount of such reduction shall not be payable before such time and to the extent as such obligation shall have been satisfied) and that no Person shall be required to claim any credit if to do so would, in its sole opinion, result in any adverse consequences to it and, provided, further, that no Person shall be required to claim any credit in respect of this Clause 5.3 in priority of any other credits (any utilization of such credit being in such Person's sole discretion). Any refund or credit which is subsequently disallowed in whole or in part shall be promptly repaid by the Borrower on the demand of the Security Trustee, the Facility Agent or relevant Lender. (g) Each Lender hereby agrees to indemnify the Borrower or the Security Trustee, as the case may be, for any Taxes of a type collected by way of withholding which the Borrower or the Security Trustee fails to withhold on payments to such Lender as a direct result of the failure of such Lender to provide the form or certificate required to be provided by such Lender by Clause 5.3(d) or the invalidity of any such form or certificate required to be provided by such Lender by Clause 5.3(d). (h) Without limiting the foregoing, each Person that is an assignee of a Lender pursuant to Clause 5.6 and/or Clause 19.3(b) shall, upon the effectiveness of such transfer, be required to provide all of the forms and statements to the extent required pursuant to this Clause 5.3. (i) The Borrower will pay to each Indemnitee interest at the Past Due Rate, to the extent permitted by Applicable Law, on any amount not paid when due under this Clause 5.3 until the same shall be paid. (j) The Borrower agrees to pay any present or future stamp or documentary Taxes or any other license, excise or property Taxes (i) imposed by any taxing authority which may arise from the registration, filing, recording, or perfection of any security interest of or in connection with this Agreement or the other Operative Documents or (ii) imposed by any taxing authority in connection with an Event of Default. The Borrower will provide appropriate documentation, including receipts if available, when requested to evidence payment by the Borrower of any such Taxes. 24006693130-v4 - 15 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] (k) All consideration expressed to be payable under an Operative Document by any party to any Finance Party shall be deemed to be exclusive of any VAT. If VAT is chargeable on any supply made by any Finance Party to any party in connection with an Operative Document, that party shall pay to the Lender (in addition to and at the same time as paying the consideration) an amount equal to the amount of the VAT. Where an Operative Document requires any party to reimburse the Lender for any costs or expenses, that party shall also at the same time pay and indemnify the Lender against all VAT incurred by the Lender in respect of the costs or expenses to the extent that the Lender reasonably determines that neither it nor any other member of any group of which it is a member for VAT purposes is entitled to credit or repayment from the relevant tax authority in respect of the VAT. (l) If a payment made to a Lender under any Operative Document would be subject to withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Security Trustee at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Security Trustee such documentation prescribed by Applicable Law including as prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Security Trustee as may be necessary for the Borrower and the Security Trustee to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (l), "FATCA" shall include all amendments made to FATCA after the Original Signing Date. 5.4 Distribution of Funds Received (a) The Facility Agent shall maintain records of all amounts paid to it by the Borrower hereunder. (b) Provided that no Event of Default has occurred and is then continuing, each installment of interest payable on the Loan Certificates shall be distributed as promptly as possible on or after the date that such amount is actually received by the Facility Agent from the Borrower: First, to the Lenders ratably, without priority of one over the other, to the payment in full of (A) the aggregate amount of interest due under the Loan Certificates in an amount equal to (i) accrued interest at the rate provided in each Loan Certificate, (ii) any overdue interest thereon, and (iii) the breakage costs, if any, and (B) any other amounts (other than principal) then due and owing to the Lenders or any Agent hereunder and under the other Operative Documents; Second, the balance, if any, thereof thereafter remaining to the Borrower or such other Person(s) as may then lawfully be entitled thereto. 24006693130-v4 - 16 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] (c) Provided that no Event of Default has occurred and is then continuing, on the Delivery Date of the related Aircraft, each payment made by the Borrower as repayment of Loans shall be distributed as promptly as possible on or after the date that such amount is actually received by the Facility Agent from the Borrower: First, to the Lenders ratably, without priority of one over the other, to the payment in full of (A) the aggregate amount of interest due under the Loan Certificates in respect of such Aircraft being in an amount equal to (i) accrued interest at the rate provided in each Loan Certificate, and (ii) any overdue interest thereon plus the breakage costs, if any, due to the Lenders in respect of such payment, and (B) any other amounts (other than principal) then due and owing to the Lenders or any Agent hereunder and under the other Operative Documents; Second, to the Lenders ratably, without priority of one over the other, to the payment in full of the outstanding principal amount of the Loans in respect of such Aircraft made by the Lenders which is being repaid; Third, the balance, if any, thereof thereafter remaining to the Borrower or such other Person(s) as may then lawfully be entitled thereto. (d) Upon any partial optional repayment of the Loan Certificates pursuant to Clause 5.10(a) hereof, the amount paid by Borrower shall be applied against the amounts which Borrower is obligated to pay in connection with such prepayment pursuant to Clause 5.10(a) (it being understood that no prepayment shall be permitted under Clause 5.10(a) unless the Borrower pays a sufficient amount to satisfy the amounts owed by it under Clause 5.10(a) in connection with such prepayment). (e) After an Event of Default shall have occurred, and so long as such Event of Default shall be continuing, amounts actually received by the Security Trustee from the Borrower and all proceeds resulting from any sale of any of the Collateral shall be applied in the following order of priority: First, to the extent not theretofore paid by or on behalf of the Borrower, to pay all costs and expenses of each Agent incurred in connection with the performance of its duties hereunder or under any other Operative Document, including reasonable attorneys' fees and expenses, and all costs and expenses incurred by the Security Trustee in connection with its entering upon, taking possession of, holding, operating, managing, selling or otherwise disposing of the Collateral or any part thereof, any and all Taxes, assessments or other charges of any kind prior to the Lien of any Operative Document that the Security Trustee determined in good faith to pay or be paid, and all amounts payable to each Agent hereunder or under any of the Operative Documents in respect of any indemnities or other obligations of the Borrower; Second, to the Lenders ratably, without priority of one over the other, to the payment of all accrued and unpaid interest (including the breakage costs, if any, 24006693130-v4 - 17 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] and interest on account of overdue payments of principal and interest) then due the Lenders under this Agreement or any of Loan Certificates; Third, to the Lenders ratably, without priority of one over the other, to the payment of any other amount, indebtedness or obligations (other than principal) due and payable to the Lenders under any Operative Documents; Fourth, to the Lenders ratably, without priority of one over the other, to the payment in full of the principal amount of the Loan Certificates; Fifth, the balance, if any, thereof thereafter remaining, to the Borrower or such other Person(s) as may then lawfully be entitled thereto. If the Security Trustee purchases and subsequently sells any Aircraft to a third party (or otherwise disposes of any of its rights under the Operative Documents relating to such Aircraft), any net sale proceeds (after deduction of all relevant costs, including maintenance, storage and insurance) which exceed the Loan allocable to such Aircraft to the extent actually received by the Security Trustee shall be distributed under this Clause (e). 5.5 Method of Payment (a) Principal and interest and other amounts due hereunder or under the Loan Certificates or in respect hereof or thereof shall be payable in Dollars in immediately available funds prior to [***], on the due date thereof, to the Facility Agent and the Facility Agent shall, subject to the terms and conditions of Clause 5.4, remit all such amounts so received by it to the Lenders at such account or accounts at such financial institution or institutions in New York as the Lenders shall have designated to the Facility Agent in writing, in immediately available funds for distribution to the relevant Lenders. (b) All such payments by the Borrower and the Facility Agent shall be made free and clear of and without reduction on account of all wire and other like charges. Prior to the due presentment for registration of transfer of any Loan Certificate, the Borrower and the Facility Agent may deem and treat the Person in whose name any Loan Certificate is registered on the Certificate Register as the absolute owner of such Loan Certificate for the purpose of receiving payment of all amounts payable with respect to such Loan Certificate and for all other purposes whether or not such Loan Certificate shall be overdue, and neither the Borrower nor the Facility Agent shall be affected by any notice to the contrary. (c) If the Facility Agent disburses funds on a payment date without first having received funds from the Borrower and if the Borrower subsequently fails to make such payment before the end of the day, then on the next succeeding Business Day following demand from the Facility Agent, each Lender which has received such funds will refund to the Facility Agent the amount advanced by the Facility Agent which such Lender received.

(b) Prior to the due presentment for registration of the transfer of any Loan Certificate, the Borrower and the Facility Agent shall deem and treat the person in whose name such Loan Certificate is registered on the Certificate Register as the absolute owner of such Loan Certificate, and the Lender for the purpose of receiving payment of all amounts payable with respect to such Loan Certificate, and for all other purposes whether or not such Loan Certificate is overdue, and neither the Borrower nor the Facility Agent shall be affected by notice to the contrary.

(b) Without limiting the effect of the foregoing provisions of this Clause 5.11 (but without duplication), the Borrower shall pay directly to each Lender from time to time on request such amounts as such Lender may determine to be necessary to compensate such Lender (or, without duplication, the bank holding company of which such Lender is a subsidiary) for any increase in costs that it determines are attributable to the maintenance by such Lender (or any lending office or such bank holding company) of capital in respect of the Commitments or Loan of such Lender hereunder, pursuant to any law or regulation or any interpretation, directive or request (whether or not having the force of law and whether or not failure to comply therewith would be unlawful so long as compliance therewith is standard banking practice in the relevant jurisdiction) of any court or governmental or monetary authority following: (i) any Regulatory Change; or (ii) implementing any risk-based capital guideline or other similar requirement issued by any government or governmental or supervisory authority implementing at the national level the Basel Accord; or (iii) implementing any requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act; in each case after the Original Signing Date (such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender (or any lending office or such bank holding company) could have achieved but for such law, regulation, interpretation, directive or request). For purposes of this Clause 5.11(b), "Basel Accord" means the proposals for risk-based capital framework described by the Basel Committee on Banking Regulations and Supervisory Practices commonly known as Basel III, as amended, modified and supplemented and in effect from time to time, or any replacement thereof. (c) Clauses 5.11(d) and (e) apply in respect of this Clause 5.11. (d) Each Lender shall notify the Borrower of any event occurring after the Original Signing Date entitling such Lender to compensation under paragraph (a) or (b) of this Clause 5.11 as promptly as practicable, but in any event within [***], after such Lender obtains actual knowledge thereof; provided that (i) such Lender shall, with respect to compensation payable pursuant to this Clause 5.11 in respect of any Additional Costs resulting from such event, only be entitled to payment under this Clause 5.11 for Additional Costs incurred from and after the date that is [***] prior to the date of receipt of such notice by the Borrower, (ii) each Lender will use 24006693130-v4 - 24 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] commercially reasonable efforts (at the Borrower's expense) to mitigate the amount of compensation under paragraph (a) or (b) of this Clause 5.11 associated with such event, including designating a different lending office for the Loan evidenced by such Lender's Loan Certificate affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, result in any economic, legal or regulatory disadvantage to such Lender, and (iii) no Lender shall discriminate against the Borrower in making any claim for compensation under this Clause 5.11, and no Lender shall treat the Borrower less favorably than such Lender's other similarly situated borrowers. When submitting a claim pursuant to Clause 5.11, each Lender will furnish to the Borrower an officer's certificate setting forth in reasonable detail (x) the events giving rise to compensation under paragraph (a) or (b) of this Clause 5.11, (y) the basis for determining and allocating such compensation and (z) the amount of each request by such Lender for such compensation (subject, however, to any limitations such Lender may require in respect of disclosure of confidential information relating to its capital structure), together with a statement that the determinations and allocations made in respect of such compensation comply with the provisions of this Clause 5.11, including as provided by the last proviso of this paragraph (d). Determinations and allocations by any Lender for purposes of this Clause 5.11 of the effect of any Regulatory Change pursuant to Clause 5.11(a), or of the effect of capital maintained pursuant to Clause 5.11(b), on its costs or rate of return of maintaining the Loan evidenced by its Loan Certificate or its Commitment, or on amounts receivable by it in respect of its Loan Certificate, and of the amounts required to compensate such Lender under this Clause 5.11, shall be conclusive absent manifest error; provided that such determinations and allocations are made on a reasonable basis and, in the case of allocations, are made fairly. (e) The Borrower shall not be required to make payments under this Clause 5.11 to any Lender if (i) a claim hereunder arises solely through circumstances peculiar to such Lender and which do not affect commercial banks in the jurisdiction of organization of such Lender generally, (ii) such Lender is not seeking similar compensation for such costs from its borrowers generally in commercial loans, or (iii) the claim arises out of a voluntary relocation by such Lender of its lending office (it being understood that any such relocation effected pursuant to this Clause 5.11 is not "voluntary"). 5.12 Illegality Notwithstanding any other provision of this Agreement or the Mortgage, if any Lender (an "Illegal Lender") shall notify the Facility Agent that the introduction after the Original Signing Date of or any change after the Original Signing Date in or in the interpretation of any law or regulation shall make it unlawful, or any central bank or other Governmental Entity asserts that it is unlawful, for such Lender to make, fund or allow to remain outstanding its Loan Certificate, then such Lender shall, promptly after becoming aware of the same, deliver to the Borrower through the Facility Agent a certificate to that effect, and, if the Facility Agent on behalf of such Lender so requires, the Borrower shall attempt to cure such illegality or otherwise, on or before [***] (but in any event at least [***] before 24006693130-v4 - 25 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] such illegality occurs and if such illegality has already occurred, immediately) following such notification, the Borrower shall prepay the aggregate outstanding principal amount of the Loan Certificate held by such Illegal Lender in full, together with accrued interest thereon to the date of prepayment plus the breakage costs, if any, and all other amounts due thereunder and hereunder and under the other Operative Documents to such Illegal Lender. 5.13 Inability to Determine Rates. Subject to Clause 5.14, if, on or prior to the first day of any Interest Period for any SOFR Loan: (a) the Facility Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof, or (b) the Majority Lenders determine that for any reason in connection with any request for a SOFR Loan or a conversion thereto or a continuation thereof that Term SOFR for any requested Interest Period with respect to a proposed SOFR Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, and the Required Lenders have provided notice of such determination to the Facility Agent, the Facility Agent will promptly so notify the Borrower and each Lender. Upon notice thereof by the Facility Agent to the Borrower, any obligation of the Lenders to make SOFR Loans, and any right of the Borrower to continue SOFR Loans or to convert ABR Loans to SOFR Loans, shall be suspended (to the extent of the affected SOFR Loans or affected Interest Periods) until the Facility Agent (with respect to clause (b), at the instruction of the Majority Lenders) revokes such notice. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of SOFR Loans (to the extent of the affected SOFR Loans or affected Interest Periods) or, failing that, the Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to ABR Loans in the amount specified therein and (ii) any outstanding affected SOFR Loans will be deemed to have been converted into ABR Loans at the end of the applicable Interest Period. Upon any such conversion, the Borrower shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to Clause 5.11. Subject to Clause 5.14, if the Facility Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof on any given day, the interest rate on ABR Loans shall be determined by the Facility Agent without reference to clause (c) of the definition of “ABR” until the Facility Agent revokes such determination. 5.14 Benchmark Replacement Setting (a) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Operative Document, upon the occurrence of a Benchmark Transition Event, the Facility Agent and the Borrower may amend this Agreement to replace

24006693130-v4 - 26 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] the then-current Benchmark with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at [***] after the Facility Agent has posted such proposed amendment to all affected Lenders and the Borrower so long as the Facility Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Majority Lenders. No replacement of a Benchmark with a Benchmark Replacement pursuant to this Clause 5.14(a) will occur prior to the applicable Benchmark Transition Start Date. (b) Benchmark Replacement Conforming Changes. In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Facility Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Operative Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Operative Document. (c) Notices; Standards for Decisions and Determinations. The Facility Agent will promptly notify the Borrower and the Lenders of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Facility Agent will notify the Borrower of (x) the removal or reinstatement of any tenor of a Benchmark pursuant to Clause 5.14(d) and (y) the commencement of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Facility Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Clause 5.14, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Operative Document, except, in each case, as expressly required pursuant to this Clause 5.14. (d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Operative Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Facility Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative, then the Facility Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark 24006693130-v4 - 27 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] Replacement) or (B) is not, or is no longer, subject to an announcement that it is not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Facility Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor. (e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any pending request for a SOFR Borrowing of, conversion to or continuation of SOFR Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to ABR Loans. During a Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of ABR based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of ABR. 6. TERMINATION OF INTEREST IN COLLATERAL None of the Facility Agent, Security Trustee or any Lender shall have any further interest in, or other right with respect to, the Collateral with respect to any Aircraft when and if the principal amount of, the breakage costs on, if any, interest on and other amounts due under all Loans in relation to such Aircraft held by such Lender and all other sums due to such Lender hereunder and under the other Operative Documents in respect of such Aircraft shall have been finally and indefeasibly paid in full; provided, however, that the interests and rights of the Lenders in and with respect to the mortgage and security interests created by the Mortgage shall continue (except with respect to any Aircraft as to which the related Loans have been repaid) after all such amounts have been paid in full so long as no Event of Default has occurred and is continuing and the Commitments have not terminated. Upon payment in full of any Loans relating to an Aircraft, the Security Trustee shall release that portion of the Collateral which relates solely to the applicable Aircraft from the Lien of the Mortgage and such Aircraft shall thereafter cease to be an "Aircraft" for the purposes of the Operative Documents. 7.

The Indemnitee agrees to give such further assurances or agreements and to cooperate with the Borrower to permit the Borrower to pursue such claims, if any, to the extent reasonably requested by the Borrower at no cost or liability to itself, and (if so requested) subject to being indemnified with respect to the Borrower's pursuit of such claims. 8.8 In the event that the Borrower shall have paid an amount to an Indemnitee pursuant to this Clause 8, and such Indemnitee subsequently shall be reimbursed in respect of such indemnified amount from any other Person, such Indemnitee shall promptly pay the Borrower the amount of such reimbursement, including interest received attributable thereto (but net of costs, if any, of recovery of such amounts), provided that no Default or Event of Default has occurred and is continuing. 8.9 The Borrower will pay to each Indemnitee on demand, to the extent permitted by Applicable Law, interest on any amount of indemnity not paid when due pursuant to this Clause 8 until the same shall be paid, at the Past Due Rate. 8.10 To the fullest extent permitted by Applicable Law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Operative Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No Indemnitee referred to in this Clause 8 shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic

24006693130-v4 - 34 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] or other information transmission systems in connection with this Agreement or the other Operative Documents or the transactions contemplated hereby or thereby. 9.

Appointment of the Facility Agent 1.1 Each of the Lenders appoints the Facility Agent to act as its agent under and in connection with the Operative Documents. 1.2 Each of the Lenders authorizes the Facility Agent to exercise the rights, powers, authorities and discretions specifically given to the Facility Agent under or in connection with the Operative Documents together with any other incidental rights, powers, authorities and discretions. 1.3 Unless expressly provided otherwise in the Operative Documents, each of the Lenders shall exercise its rights through the Facility Agent or the Security Trustee. 2. Duties of the Facility Agent 2.1 (a) The Facility Agent shall promptly forward to a Party the original or a copy of any document which is delivered to the Facility Agent for that Party by any other Party. (b) Paragraph (a) above shall not apply to any assignment agreement executed pursuant to clause 19.3(b)(i) or (ii). 2.2 The Facility Agent shall promptly forward to each of the Lenders a copy of any document or notice which is delivered to the Facility Agent by the Security Trustee. 2.3 If the Facility Agent receives notice from a Party referring to this Agreement, describing a Default and stating that the circumstance described is a Default, it shall promptly notify the Lenders. 2.4 The Facility Agent shall promptly notify the Lenders of any Default (in relation to which it has actual knowledge) arising under Clause 4(a) (Non Payment) of the Mortgage. 2.5 The Facility Agent's duties under the Operative Documents are solely mechanical and administrative in nature. 2.6 Except where an Operative Document expressly and specifically provides otherwise, the Facility Agent is not obliged to review or check the adequacy, accuracy or completeness of any document it forwards to another Party. 3. No fiduciary duties 3.1 Nothing in this Agreement constitutes the Facility Agent as a trustee or fiduciary of any other Person.

24006693130-v4 - 6 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] 3.2 The Facility Agent shall not be bound to account to any Lender for any sum or the profit element of any sum received by it for its own account. 4. Business with the Borrower The Facility Agent may accept deposits from, lend money to and generally engage in any kind of banking or other business with any member of the Group. 5. Rights and discretions of the Facility Agent 5.1 The Facility Agent may rely on: (a) any representation, notice or document believed by it to be genuine, correct and appropriately authorized; and (b) any statement made by a director, authorized signatory or employee of any person regarding any matters which may reasonably be assumed to be within his knowledge or within his power to verify. 5.2 The Facility Agent may assume (unless it has received notice to the contrary in its capacity as agent for the Lenders) that: (a) no Default has occurred (unless it has actual knowledge of a Default arising under clause 4(a) (Non-Payment) of the Mortgage); and (b) any right, power, authority or discretion vested in any Party or the Majority Lenders has not been exercised. 5.3 The Facility Agent may engage, pay for and rely on the advice or services of any lawyers, accountants, surveyors or other experts provided that such engagement shall not cause any additional expense or cost to the Borrower or any Guarantor unless approved in advance in writing by either such Guarantor. 5.4 The Facility Agent may act in relation to the Operative Documents through its personnel and agents. 5.5 The Facility Agent may disclose to any other Party any information it reasonably believes it has received as agent under this Agreement. 5.6 Notwithstanding any other provision of any Operative Document to the contrary, the Facility Agent is not obliged to do or omit to do anything if it would or might in its reasonable opinion constitute a breach of any law or regulation or a breach of a fiduciary duty or duty of confidentiality. 6. Majority Lenders' instructions 6.1 Unless a contrary indication appears in an Operative Document, the Facility Agent shall act in accordance with any instructions given to it by the Majority Lenders (or, if so 24006693130-v4 - 7 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] instructed by the Majority Lenders, refrain from acting or exercising any right, power, authority or discretion vested in it as Facility Agent) and shall not be liable for any act (or omission) if it acts (or refrains from taking any action) in accordance with such an instruction of the Majority Lenders. 6.2 Unless a contrary indication appears in an Operative Document, any instructions given by the Majority Lenders will be binding on all the Lenders. 6.3 The Facility Agent may refrain from acting in accordance with the instructions of the Majority Lenders (or, if appropriate, the Lenders) until it has received such security as it may require for any cost, loss or liability (together with any associated VAT) which it may incur in complying with the instructions. 6.4 In the absence of instructions from the Majority Lenders, (or, if appropriate, the Lenders) the Facility Agent may act (or refrain from taking action) as it considers to be in the best interest of the Lenders. 6.5 The Facility Agent is not authorized to act on behalf of a Lender (without first obtaining that Lender's consent) in any legal or arbitration proceedings relating to any Operative Document. 7. Responsibility for documentation The Facility Agent is not (i) responsible for the legality, validity, effectiveness, adequacy or enforceability of any Operative Document or any other agreement, arrangement or document entered into, made or executed in anticipation of or in connection with any Operative Document or (ii) responsible for any determination as to whether any information provided or to be provided to any Finance Party is non-public information the use of which may be regulated or prohibited by Applicable Law or regulation relating to insider dealing or otherwise, unless the Facility Agent is informed by the Borrower or any Guarantor in writing that specific information being provided to the Facility Agent is non- public information. 8. Exclusion of liability 8.1 Without limiting sub-clause 8.2, the Facility Agent will not be liable for any action taken by it under or in connection with any Operative Document, unless directly caused by its gross negligence or willful misconduct. 8.2 No Party may take any proceedings against any officer, employee or agent of the Facility Agent in respect of any claim it might have against the Facility Agent or in respect of any act or omission of any kind by that officer, employee or agent in relation to any Operative Document and any officer, employee or agent of the Facility Agent may rely on this sub- clause. Any third party referred to in this sub-clause 8.2 may enjoy the benefit of and enforce the terms of this sub-clause 8.2. 8.3 The Facility Agent will not be liable for any delay (or any related consequences) in crediting an account with an amount required under the Operative Documents to be paid 24006693130-v4 - 8 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] by the Facility Agent if the Facility Agent has taken all necessary steps as soon as reasonably practicable to comply with the regulations or operating procedures of any recognized clearing or settlement system used by the Facility Agent for that purpose. 8.4 Nothing in this Agreement shall oblige the Facility Agent to carry out any "know your customer" or other checks in relation to any person on behalf of any Lender and each Lender confirms to the Facility Agent that it is solely responsible for any such checks it is required to carry out and that it may not rely on any statement in relation to such checks made by the Facility Agent. 9. Lenders' indemnity to the Facility Agent Each Lender shall (in proportion to its share of the total Commitments or, if the total Commitments are then zero, to its share of the total Commitments immediately prior to their reduction to zero) indemnify the Facility Agent, within [***] of demand, against any cost, loss or liability incurred by the Facility Agent (otherwise than by reason of the Facility Agent's gross negligence or willful misconduct) in acting as Facility Agent under the Operative Documents (unless the Facility Agent has been reimbursed by the Borrower pursuant to an Operative Document). 10. Resignation of the Facility Agent 10.1 The Facility Agent may resign and appoint one of its Affiliates as successor by giving notice to the other Finance Parties and the Borrower. 10.2 Alternatively, the Facility Agent may resign with the consent of the Borrower (such consent not to be unreasonably withheld or delayed and provided that, such consent shall not be required if there shall have occurred and be continuing an Event of Default) by giving notice to the Lenders, in which case the Majority Lenders (after consultation with the Borrower) may appoint a successor Facility Agent. 10.3 If the Majority Lenders have not appointed a successor Facility Agent in accordance with sub-clause 10.2 within [***] after notice of resignation was given, the Facility Agent (after consultation with the Borrower) may appoint a successor Facility Agent. 10.4 The retiring Facility Agent shall, at its own cost, make available to the successor Facility Agent such documents and records and provide such assistance as the successor Facility Agent may reasonably request for the purposes of performing its functions as Facility Agent under the Operative Documents. 10.5 The Facility Agent's resignation notice shall only take effect upon the appointment of a successor. 10.6 Upon the appointment of a successor, the retiring Facility Agent shall be discharged from any further obligation in respect of the Operative Documents but shall remain entitled to the benefit of this Clause 10. Its successor and each of the other Parties shall have the same rights and obligations amongst themselves as they would have had if such successor had been an original Party. 24006693130-v4 - 9 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] 10.7 With (prior to the occurrence of an Event of Default that is continuing) the consent of the Borrower (such consent not to be unreasonably withheld or delayed), the Majority Lenders may, by notice to the Facility Agent, require it to resign in accordance with sub-clause 10.2. In this event, the Facility Agent shall resign in accordance with sub-clause 10.2. 11. Confidentiality 11.1 In acting as agent for the Lenders, the Facility Agent shall be regarded as acting through its agency division which shall be treated as a separate entity from any other of its divisions or departments. 11.2 If information is received by another division or department of the Facility Agent, it may be treated as confidential to that division or department and the Facility Agent shall not be deemed to have notice of it. 11.3 Notwithstanding any other provision of any Operative Document to the contrary, the Facility Agent is not obliged to disclose to any other person any confidential information or any other information if the disclosure would or might in its reasonable opinion constitute a breach of any law or a breach of a fiduciary duty. 12. Relationship with the Lenders The Facility Agent may treat each Lender as a Lender, entitled to payments under this Agreement and acting through its Facility Office unless it has received not less than [***] prior notice from that Lender to the contrary in accordance with the terms of this Agreement. 13. Credit appraisal by the Lenders Without affecting the responsibility of the Obligors for information supplied by it or on its behalf in connection with any Operative Document and the transactions contemplated thereby, each Lender confirms to the Facility Agent that it has been, and will continue to be, solely responsible for making its own independent appraisal and investigation of all risks arising under or in connection with any Operative Document including but not limited to: 13.1 the financial condition, status and nature of the Obligors; 13.2 the legality, validity, effectiveness, adequacy or enforceability of any Operative Document and any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Operative Document; 13.3 whether that Lender has recourse, and the nature and extent of that recourse, against any Party or any of its respective assets under or in connection with any Operative Document, the transactions contemplated by the Operative Documents or any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Operative Document; and

24006693130-v4 - 10 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] 13.4 the adequacy, accuracy and/or completeness of any information provided by any Party or by any other person under or in connection with any Operative Document, the transactions contemplated by the Operative Documents or any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Operative Document. 14. Written Directions The Borrower shall be entitled to rely on any written direction believed by it (acting reasonably) to be given by the Facility Agent or the Security Trustee, as the case may be, as having been authorized, to the extent required by this Agreement, by all the Finance Parties. 15. Erroneous Payments 15.1 If the Facility Agent (x) notifies a Lender, the Security Trustee, or any Person who has received funds on behalf of a Lender, the Security Trustee (any such Lender, the Security Trustee or other recipient (and each of their respective successors and assigns), a "Payment Recipient") that the Facility Agent has determined in its sole discretion (whether or not after receipt of any notice under immediately succeeding Clause 15.2) that any funds (as set forth in such notice from the Facility Agent) received by such Payment Recipient from the Facility Agent or any of its Affiliates were erroneously or mistakenly transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender, the Security Trustee or other Payment Recipient on its behalf) (any such funds, whether transmitted or received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an "Erroneous Payment") and (y) demands in writing the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Facility Agent pending its return or repayment as contemplated below in this Clause 15 and held in trust for the benefit of the Facility Agent, and such Lender or Security Trustee shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than [***] thereafter (or such later date as the Facility Agent may, in its sole discretion, specify in writing), return to the Facility Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon (except to the extent waived in writing by the Facility Agent) in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Facility Agent in same day funds at the greater of the Federal Funds Rate and a rate determined by the Facility Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Facility Agent to any Payment Recipient under this Clause 15.1 shall be conclusive, absent manifest error. 15.2 Without limiting immediately preceding Clause 15.1, each Lender, the Security Trustee or any Person who has received funds on behalf of a Lender or the Security Trustee (and each of their respective successors and assigns), agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, 24006693130-v4 - 11 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] interest, fees, distribution or otherwise) from the Facility Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in this Agreement or in a notice of payment, prepayment or repayment sent by the Facility Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Facility Agent (or any of its Affiliates), or (z) that such Lender, Issuing Bank or Secured Party, or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part), then in each such case: (a) it acknowledges and agrees that (A) in the case of immediately preceding clauses (x) or (y), an error and mistake shall be presumed to have been made (absent written confirmation from the Facility Agent to the contrary) or (B) an error and mistake has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and (b) such Lender or Security Trustee shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within [***] of its knowledge of the occurrence of any of the circumstances described in immediately preceding clauses (x), (y) and (z)) notify the Facility Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Facility Agent pursuant to this Clause 15.2(b). For the avoidance of doubt, the failure to deliver a notice to the Facility Agent pursuant to this Clause 15.2(b) shall not have any effect on a Payment Recipient's obligations pursuant to Clause 15.2(a) or on whether or not an Erroneous Payment has been made. 15.3 Each Lender, Issuing Bank or Secured Party hereby authorizes the Facility Agent to set off, net and apply any and all amounts at any time owing to such Lender or Financing Party under any Operative Document, or otherwise payable or distributable by the Facility Agent to such Lender or Financing Party under any Operative Document with respect to any payment of principal, interest, fees or other amounts, against any amount that the Facility Agent has demanded to be returned under immediately preceding Clause 15.1. 15.4 (i) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Facility Agent for any reason, after demand therefor in accordance with immediately preceding Clause 15.1, from any Lender that has received such Erroneous Payment (or portion thereof) (and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an "Erroneous Payment Return Deficiency"), upon the Facility Agent's notice to such Lender at any time, then effective immediately (with the consideration therefor being acknowledged by the parties hereto), (A) such Lender shall be deemed to have assigned its Loans (but not its Commitments) with respect to which such Erroneous Payment was made (the "Erroneous Payment Impacted Class") in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Facility Agent may specify) (such assignment of the Loans (but not Commitments) of the Erroneous Payment Impacted Class, the "Erroneous Payment Deficiency Assignment") (on a cashless basis and such amount 24006693130-v4 - 12 - 80-40605773 [Citi/Frontier A320neo/A321neo PDP Ninth Amended and Restated Credit Agreement] calculated at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Facility Agent in such instance)), and is hereby (together with the Borrower) deemed to execute and deliver an Assignment and Assumption Agreement (or, to the extent applicable, an agreement incorporating an Assignment and Assumption Agreement by reference pursuant to an approved electronic platform as to which the Facility Agent and such parties are participants) with respect to such Erroneous Payment Deficiency Assignment, and such Lender shall deliver any Loan Certificates evidencing such Loans to the Borrower or the Facility Agent (but the failure of such Person to deliver any such Notes shall not affect the effectiveness of the foregoing assignment), (B) the Facility Agent as the assignee Lender shall be deemed to have acquired the Erroneous Payment Deficiency Assignment, (C) upon such deemed acquisition, the Facility Agent as the assignee Lender shall become a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Lender, (D) the Facility Agent and the Borrower shall each be deemed to have waived any consents required under this Agreement to any such Erroneous Payment Deficiency Assignment, and (E) the Facility Agent will reflect in the Certificate Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment.
