Customer under the Purchase Agreement, and (B) to Engine Manufacturer to perform all the duties and obligations of Airline under the GTA, in each case to the same extent as if this Security Agreement had not been
executed;

(2) Security Agents exercise of any of the rights assigned hereunder shall not release Borrower from any of
its duties or obligations to Airframe Manufacturer under the Purchase Agreement or to Engine Manufacturer under the GTA, except to the extent that such exercise constitutes performance of such duties and obligations; and

(3) except as provided in the next paragraph, neither Security Agent nor any Lender shall have any obligation or liability under the
Purchase Agreement or the GTA by reason of, or arising out of, this Security Agreement, or be obligated to perform any of Borrowers obligations or duties under the Purchase Agreement or the GTA, or to make any payment thereunder, or to make
any inquiry as to the sufficiency of any payment received by any of them, or to present or file any claim or to take any other action to collect or enforce any claim for any payment assigned under this Security Agreement.

Notwithstanding anything to the contrary in this Security Agreement, the Consent and Agreement or the
Engine Consent and Agreement, but without in any way releasing Borrower from any of its duties or obligations under the Purchase Agreement, the GTA, or this Security Agreement, Security Agent confirms for the benefit of Airframe Manufacturer and
Engine Manufacturer that, insofar as the provisions of the Purchase Agreement or the GTA relate to the Aircraft or the Engines (respectively), in exercising any rights under the Purchase Agreement or under the GTA, or in making any claim with
respect to the Aircraft, Engines or other goods and services delivered or to be delivered pursuant to the Purchase Agreement or the GTA, the terms and conditions thereof (including warranty disclaimers, liability exclusions, indemnity, and
insurance) shall apply to and bind Security Agent to the same extent as Borrower. At Borrowers cost and expense, Security Agent further agrees, expressly for the benefit of Airframe Manufacturer and Engine Manufacturer, that upon the written
request of Airframe Manufacturer or Engine Manufacturer, Security Agent will promptly execute and deliver such further assurances and documents and take such further action as Airframe Manufacturer or Engine Manufacturer reasonably requests in order
to obtain the full benefits of Security Agents agreements in this paragraph. Except as provided in the Consent and Agreement and the Engine Consent and Agreement, Borrower and Security Agent understand and acknowledge that no further
assignment of the Purchase Agreement or GTA, including, without limitation, assignments for security purposes, are permitted without the express written consent of Airframe Manufacturer or Engine Manufacturer (as the case may be).

Notwithstanding any of the foregoing provisions of this Granting Clause, but subject to the express provisions of the other articles of this Security
Agreement, so long as Security Agent has not commenced the exercise of remedies under Section 4 hereof, Borrower shall have the right, to the exclusion of Security Agent and any others claiming by, through or under Security Agent, to exercise
in Borrowers name all rights and powers of (x) the Customer with respect to the Aircraft under the Purchase Agreement and (y) the Airline with respect to the Engines under the GTA, provided, that, Borrower may
not enter into any amendment, modification or supplement to either Purchase Agreement or the GTA to the extent related to the Aircraft or any right assigned hereunder without the written consent of Security Agent if such amendment, modification or
supplement would (1) result in a change to the configuration and/or specification of an Aircraft (other than by reason of modification to such Aircraft required by the FAA) that increases the purchase price thereof by an amount that alone or in
the aggregate with other configuration or specification changes is in excess of Fifty Thousand Dollars ($50,000) unless Borrower, at the time of such amendment, modification or supplement, pays the amount of such increase to Airframe Manufacturer as
an additional advance payment under the Purchase Agreement, or (2) diminish (other than in any de minimis respect) the rights assigned hereunder to Security Agent.

HABENDUM CLAUSE:

TO HAVE AND
TO HOLD all and singular the aforesaid property unto Security Agent, its successors and assigns, in trust for the benefit and security of the Lenders, and for the uses and purposes and subject to the terms and
provisions set forth in this Security Agreement.

|2. | THE CERTIFICATES
|-- | ----------------



| | 2.1 | Form of Loan Certificates.
| | --- | --------------------------

The Loan Certificates
shall be substantially in the form of Exhibit A.



| | 2.2 | Terms of Loan Certificates; Drawings.
| | --- | -------------------------------------

(a) On the
Effective Date, Borrower shall issue a Loan Certificate to each Lender in an aggregate original principal amount equal to such Lenders Maximum Commitment. Borrower shall be entitled to make Drawings under each Loan Certificate in accordance
with Section 2(a) of the Credit Agreement.

(b) Each Loan Certificate shall bear interest on the unpaid principal amount of Drawings
made thereunder from time to time outstanding from and including the date thereof until such principal amount is paid in full. Such interest shall accrue with respect to each Interest Period at the Applicable Rate in effect for such Interest Period
and shall be payable in arrears on each Interest Payment Date and on the date such Loan Certificate is paid in full. Interest hereunder and under the Loan Certificates shall be calculated on the basis of a year of 360 days and actual number of days
elapsed. If any sum payable under the Loan Certificates or under this

---

Security Agreement falls due on a day which is not a Business Day, then such sum shall be payable on the next succeeding Business Day; provided that, in the
case of principal of and interest on the Loan Certificates payable on a Interest Payment Date, if by virtue of such extension such payment would fall in the next succeeding month, such sum shall be payable on the next preceding Business Day.
Notwithstanding any provisions in the Operative Agreements to the contrary, if the Interest Period in respect of Drawings relating to an Aircraft is scheduled to commence on a date that is less than one (1) month prior to the scheduled Delivery
Date of the Aircraft to which such Drawing(s) relates, Borrower, upon written notice to Security Agent given by Borrower within five (5) Business Days prior to the commencement of such Interest Period, may designate that, for purposes of such

relates shall extend to the earlier of (1) the Delivery Date for such Aircraft and (2) the date agreed to by Security Agent.

(d) Each Loan Certificate shall bear interest at the Past Due Rate on any unpaid principal amount of Drawings made thereunder 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 respective Lender given through Security Agent.

(e) The Loan Certificates shall be executed on behalf of Borrower by one of its authorized officers. Loan Certificates bearing the

such offices at the respective dates of such Loan Certificates. No Loan Certificates shall be issued hereunder except those provided for in Section 2.2(a) and any Loan Certificates issued in exchange or replacement therefor pursuant to the

Break Loss, if any, due to the Lenders in respect of such payment; and

SECOND, to the Lenders ratably,
without priority of one over the other, to the payment in full of the unpaid principal amount of Drawings which are being repaid.

(d) Upon
any partial optional repayment of the Loan Certificates pursuant to Section 2.10(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
Section 2.10(a) (it being understood that no prepayment shall be permitted under Section 2.10(a) unless Borrower pays a sufficient amount to satisfy the amounts owed by it under Section 2.10(a) in connection with such prepayment).

interest on, and other amount due under each Loan Certificate or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 11:00 a.m., New York time, on the due date of payment to Paying Agent for
distribution in the manner provided herein (any payment received after such time being deemed received on the next following Business Day). Subject to receipt of the funds by Paying Agent as outlined above, Paying Agent will pay or cause to be paid
all amounts to be paid by Borrower hereunder and under any Loan Certificate to the holder thereof (including all amounts distributed pursuant to Section 2.4 of this Security Agreement) by transferring, or causing to be transferred, by wire
transfer of immediately available funds in Dollars to an account nominated by such holder not later than 4:00 p.m., New York time, on the date of receipt of such funds. If any such payment is received by such holder after the time specified in the
preceding sentence, then such payment shall be deemed to be received on the next following Business Day, and subject to the next sentence, Borrower shall be entitled to any interest earned on the amount of such payment and shall compensate such
holder for loss of use of funds at the Applicable Rate. If Paying Agent fails to initiate the transfer by federal wire transfer of any such payment as provided in the foregoing sentence after its receipt of funds at the place and before the time
specified above by reason of its failure to use ordinary care, Paying Agent shall compensate such holders for loss of use of funds at the Applicable Rate until such payment is made, and Paying Agent shall be entitled to any interest earned on such
funds until such payment is made. Any payment made hereunder shall be made without any presentment or surrender of any Loan Certificate, except that, in the case of the final payment in respect of any Loan Certificate, such Loan Certificate shall be
surrendered to Paying Agent for cancellation promptly after such payment. Notwithstanding any other provision of this Security Agreement to the contrary, Paying Agent shall not be required to make, or cause to be made, wire transfers as aforesaid
before the first Business Day on which it is practicable for Paying Agent to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 11:00 a.m., New York time, at the place of
payment. Before the due presentment for registration of transfer of any Loan Certificate, Borrower, Paying Agent and Security Agent shall deem and treat the Person in whose name any Loan Certificate is registered on the Certificate Register as the
absolute owner and holder of such Loan Certificate for the purpose of receiving payment of



8



---

all amounts payable with respect to such Loan Certificate and for all other purposes, and neither Borrower, Paying Agent nor Security Agent shall be affected
by any notice to the contrary. So long as any signatory to the Credit Agreement or nominee thereof shall be a registered Lender, all payments to it shall be made to the account of such Lender specified in Schedule 1 of the Credit Agreement, and
otherwise in the manner provided in or pursuant to the Credit Agreement, unless and until it specifies some other account or manner of payment by notice to Paying Agent consistent with this Section 2.5.



| | 2.6 | [Intentionally Omitted].
| | --- | ------------------------



| | 2.7 | Registration, Transfer and Exchange of Loan Certificates.
| | --- | ---------------------------------------------------------

Security Agent shall keep a register (the Certificate Register) in which Security Agent shall provide for the registration of Loan Certificates and the registration of transfers of Loan Certificates. No such transfer shall be
given effect unless and until registered hereunder. Security Agent is hereby appointed Certificate Registrar for the purpose of registering Loan Certificates and transfers of Loan Certificates as herein provided. A holder of any Loan
Certificate intending to exchange such Loan Certificate shall surrender such Loan Certificate to Security Agent, together with a written request from the registered holder thereof for the issuance of a new Loan Certificate, specifying (in the case
of a surrender for transfer) the name(s) and address(es) of the new holder(s). Upon surrender for registration of transfer of any Loan Certificate, Borrower shall execute, and Security Agent shall authenticate and deliver, in the name(s) of the
designated transferee(s), one or more new Loan Certificate of a like aggregate original principal amount At the Lenders option, Loan Certificates may be exchanged for other Loan Certificates of any authorized denominations of a like aggregate
original principal amount, upon surrender of the Loan Certificates to be exchanged to Security Agent. Whenever any Loan Certificates are so surrendered for exchange, Borrower shall execute, and Security Agent shall authenticate and deliver, the Loan
Certificates which the Lender making the exchange is entitled to receive. All Loan Certificates issued upon any registration of transfer or exchange of Loan Certificates (whether under this Section 2.7 or under Section 2.8 or otherwise
under this Security Agreement) shall be the valid obligations of Borrower evidencing the same respective obligations, and entitled to the same security and benefits under this Security Agreement, as the Loan Certificates surrendered upon such
registration of transfer or exchange. Every Loan Certificate presented or surrendered for registration of transfer, shall (if so required by Security Agent) be duly endorsed, or be accompanied by a Transfer Certificate in form satisfactory to
Security Agent duly executed by the Lender or such holders attorney duly authorized in writing. Security Agent shall make a notation on each new Loan Certificate of the amount of principal amounts of Drawings previously made under, and the
payments of principal previously made, on the old Loan Certificate or Loan Certificates with respect to which such new Loan Certificate is issued and the date to which interest on such old Loan Certificate or Loan Certificates has been paid.
Interest shall be deemed to have been paid on such new Loan Certificate to the date on which interest shall have been paid on such old Loan Certificate, and the principal amounts of Drawings and all payments of the principal marked on such new Loan
Certificate, as provided above, shall be deemed to have been made thereon. Borrower shall not be required to exchange any surrendered Loan Certificates as provided above during the 10-day period preceding the due date of any payment on such Loan
Certificate. Borrower shall in all cases deem the Person in whose name any Loan Certificate shall have been issued and registered as the absolute owner and holder of such Loan Certificate for the purpose of receiving payment of all amounts payable



9



---

by Borrower with respect to such Loan Certificate, and for all other purposes, until Borrower receives from Security Agent a notice stating otherwise and
such change is reflected on the Certificate Register. Security Agent will promptly notify Borrower of each registration of a transfer of a Loan Certificate. Any such transferee of a Loan Certificate, by its acceptance of a Loan Certificate, agrees
to the provisions of this Security Agreement and the Credit Agreement applicable to Lenders and shall be deemed to have covenanted to the parties to the Credit Agreement as to the matters covenanted by the original Lender in the Credit Agreement.
Subject to compliance by the Lender and its transferee (if any) of the requirements in this Section 2.6, Security Agent and Borrower shall use all reasonable efforts to issue new Loan Certificates upon transfer or exchange within ten
(10) Business Days of the date a Loan Certificate is surrendered for transfer or exchange.



| | 2.8 | Mutilated, Destroyed, Lost or Stolen Loan Certificates.
| | --- | -------------------------------------------------------

If any Loan Certificate shall become mutilated, destroyed, lost, or stolen, upon the written request of the holder of such Loan Certificate, Borrower shall execute, and Security Agent shall authenticate and deliver, in replacement thereof,
a new Loan Certificate of a like aggregate original principal amount and Series, dated the same date, and captioned as issued in connection with the Aircraft. If the Loan Certificate being replaced has become mutilated, such Loan Certificate shall
be surrendered to Security Agent and a photocopy thereof shall be furnished to Borrower. If the Loan Certificate being replaced has been destroyed, lost, or stolen, the holder of such Loan Certificate shall furnish to Borrower and Security Agent
(a) such security or indemnity as they require to save Borrower and Security Agent harmless, and (b) evidence satisfactory to Borrower and Security Agent of the destruction, loss, or theft of such Loan Certificate and of the ownership
thereof. If a qualified institutional buyer of the type referred to in paragraph (a)(1)(i)(A), (B), (D), or (E) of Rule 144A under the Securities Act (a QIB) is the holder of any such destroyed, lost, or stolen Loan
Certificate, then the written indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to, and in form reasonably satisfactory to Borrower shall be accepted as satisfactory indemnity and security, and no further
indemnity or security shall be required as a condition to the execution and delivery of such new Loan Certificate. Subject to the Lenders compliance with the requirements in this Section 2.8, Security Agent and Borrower shall use all
reasonable efforts to issue new Loan Certificates within ten (10) Business Days after receiving the Lenders written request therefor.



| | 2.9 | Payment of Expenses on Transfer.
| | --- | --------------------------------

(a) No service
charge shall be made to a Lender for any registration of transfer or exchange of Loan Certificates, but Security Agent, as Certificate Registrar, may require payment from any such Lender of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or exchange of Loan Certificates.

Credit Agreement, Borrower may not prepay an aggregate unpaid principal amount of less than One Million Dollars ($1,000,000); and provided, further, that notwithstanding anything to the contrary in this Security Agreement, the proceeds of any
partial prepayment shall be distributed by Paying Agent to the Lenders ratably, except in the case of a prepayment of Loan Certificates with respect to which Indemnified Withholding Taxes are then payable by Borrower pursuant to Section 10(c)
of the Credit Agreement, in which case the proceeds of such prepayment shall be distributed to the Lender or Lenders of the Loan Certificates to which such Indemnified Withholding Taxes relate. If a prepayment date is not a Payment Date, the
prepayment price shall be increased by the amount of any Break Loss associated with any such prepayment.
