International Registry cannot properly be made so long as the applicable Aircraft is registered in such jurisdiction unless a security agreement governed by the laws of such jurisdiction is entered into, then such registration with the International Registry shall not be required for so long as such Aircraft is registered in such jurisdiction (collectively, the “Required Cape Town Registrations”), provided further that (1) on or prior to the Delivery Date for an Asset, the relevant Grantor shall cause its Administrator (acting directly or through a Transacting User Entity or a Professional User Entity to whom it has given an authorization) to commence effecting the applicable registrations with the International Registry described in clauses (ii) through (v) above and (2) in connection with any registrations with the International Registry described in clause (iii) and (iv) above, the Security Trustee shall be registered as the holder of the right to discharge such registrations (except to the extent that, after use of commercially reasonable efforts by the lessor or its representatives, the Lessee under any Assigned Lease will not consent to the right to discharge the registrations with the International Registry described in clauses (iii) and (iv) above to be held by any Person other than the applicable lessor).

(d) Each Grantor shall be relieved of taking the actions specified in Section 3.12(b) or (c) if and to the extent that the Security Trustee receives an opinion of counsel based on then prevailing case law and without material qualifications to the effect that such actions are not necessary under 49 U.S.C. §44108 to establish the validity of any such Asset Mortgage, Asset Mortgage and Lease Security Assignment or Lease Security Assignment against a Person that does not have actual notice of the same, or that registration at the International Registry of the

(c) Notwithstanding anything contained herein to the contrary, payments from any property (or the proceeds thereof) deposited in the Redemption/Defeasance Account or the Refinancing Account pursuant to Section 3.11 of the Indenture or Article XI of the Indenture shall not be subordinated to the prior payment of any Senior Secured Claimants in respect of any Senior Secured Claims or subject to any other restrictions set forth in this Article IX, and none of the Holders or, if applicable, Certificate Holders or other Persons (including any Subordinated Representative), shall be obligated to pay over any such payments from any such property to the Security Trustee or any other creditor of any of the Grantors.

Section 9.06 Exercise of Remedies. (a) Until the date on which all the Senior Secured Claims shall have been paid in full, the Senior Representative, in its sole discretion and to the exclusion of the Subordinated Representatives, shall have, whether or not any default under the Indenture shall have occurred and be continuing and both before and after the commencement of any proceeding referred to in Section 9.07(a), the sole and exclusive right (as between the Senior Representative, on the one hand, and the Subordinated Representatives, on the other) to direct the Security Trustee to take all action with respect to the Collateral, including the right to exercise or direct voting or other consensual rights, to foreclose or forebear from foreclosure in respect of the Collateral and to accept the Collateral in full or partial satisfaction of any Senior Secured Claim, all in accordance with the terms of this Agreement.

(b) The Subordinated Representatives agree that, so long as any of the Senior Secured Claims shall remain unpaid, they and the Subordinated Secured Claimants will not commence, or join with any creditor other than the Security Trustee and the Senior Secured Claimants in commencing, any enforcement, collection, execution, levy or foreclosure proceeding with respect to the Collateral or proceeds of Collateral.

Section 9.07 Further Agreements of Subordination. The Subordinated Representatives agree as follows:

(a) Upon any distribution of all or any of the Collateral or proceeds of Collateral to creditors of any Grantor upon the dissolution, winding-up, liquidation, arrangement, reorganization, adjustment, protection, relief or composition of such Grantor or its debts, whether in any bankruptcy, insolvency, arrangement, reorganization, receivership, relief or similar case or proceedings or upon an assignment for the benefit of creditors or any other marshaling of the assets and liabilities of such Grantor, or otherwise, any distribution of any kind of Collateral or proceeds of Collateral that otherwise would be deliverable upon or with respect to the Subordinated Secured Claims shall be delivered directly to the Security Trustee for application (in the case of cash) to or as collateral (in the case of non-cash property or securities) for the payment or prepayment of the Senior Secured Claims until the Senior Secured Claims shall have been paid in full.

(b) If any case or proceeding referred to in Section 9.07(a) is commenced by or against any Grantor:

(i) the Security Trustee is hereby irrevocably authorized and empowered (in its own name or in the name of the Secured Parties or otherwise), but shall have no obligation, to demand, sue for, collect and receive every distribution referred to in subsection (a) above and give acquittance therefor and to file claims and proofs of claim and take such other action (including enforcing this Agreement) as it may deem necessary or advisable, or as the Senior Representative may direct, for the exercise or enforcement of any of the rights or interests of the Senior Secured Claimants hereunder; and

(ii) the Subordinated Representatives shall duly and promptly take such action, at the expense of the Issuer, as the Senior Representative may request (A) to collect Collateral and proceeds of Collateral for the account of the Senior Secured Claimants and to file appropriate claims or proofs of claim in respect of Collateral and proceeds of Collateral, (B) to execute and deliver to the Security Trustee such powers of attorney, assignments or other instruments as the Senior Representative may request in order to enable it to enforce any and all claims with respect to the Collateral and proceeds of Collateral and (C) to collect and receive any and all payments or distributions that may be payable or deliverable upon or with respect to the Collateral or proceeds of Collateral. Without limiting the generality of any of the foregoing, if any proceeding referred to in Section 9.07(a) is commenced by or against any Grantor, the Subordinated Secured Claimants shall, upon written demand from the Senior Representative or the Security Trustee, file such claims in such proceeding as the Senior Representative or the Security Trustee, as applicable, shall request in such written demand or any subsequent written

demand provided in connection therewith; provided, however, that should one or more Subordinated Secured Claimants fail to comply fully with any such demand within 30 days of receipt by such Subordinated Secured Claimant of the relevant demand, such Subordinated Secured Claimant (by holding its respective Notes or Beneficial Interest Certificate or the execution of a Secured Party Supplement or this Agreement) shall be deemed to have irrevocably appointed the Security Trustee its attorney-in-fact to file and prosecute any such claim and to dispose of any proceeds of such filing or prosecution in accordance with the terms hereof and of the other Related Documents.

(c) All payments or distributions upon or with respect to the Collateral or proceeds of Collateral that are received by the Subordinated Representatives or the Subordinated Secured Claimants contrary to the provisions of this Agreement shall be received for the benefit of the Senior Secured Claimants, shall be segregated from other funds and property held by the Subordinated Representatives or the Subordinated Secured Claimants and shall be forthwith paid over to the Security Trustee in the same form as so received (with any necessary endorsement) to be applied (in the case of cash) to or held as collateral (in the case of non-cash property or securities) for the payment or prepayment of the Senior Secured Claims in accordance with the terms thereof.

(d) The Senior Representative is hereby authorized to demand specific performance of this Agreement at any time when any of the Subordinated Representatives or the Subordinated Secured Claimants shall have failed to comply with any of the provisions of this Agreement applicable to them. The Subordinated Representatives hereby irrevocably waive, on their own behalf and on behalf of the Subordinated Secured Claimants, to the fullest extent permitted by applicable law, any defense based on the adequacy of a remedy at law that might be asserted as a bar to such remedy of specific performance.

Section 9.08 Rights of Subrogation. The Subordinated Representatives agree that no payment or distributions to the Senior Representative or the Senior Secured Claimants pursuant to the provisions of this Agreement shall entitle any Subordinated Representative or any Subordinated Secured Claimant to exercise any rights of subrogation in respect thereof until all obligations constituting Senior Secured Claims with respect to such Person shall have been paid in full.

Section 9.09 Further Assurances of Subordinated Representatives. Each of the Subordinated Representatives shall, at the expense of the Issuer, at any time and from time to time promptly execute and deliver all further instruments and documents, and take all further action, that the Senior Representative or the Security Trustee may reasonably request, in order to protect any right or interest granted or purported to be granted hereby or to enable the Senior Representative and the Security Trustee to exercise and enforce their rights and remedies hereunder.

(b) Each of the Subordinated Representatives waives, on its own behalf and on behalf of the Subordinated Secured Claimants, to the fullest extent permitted by applicable law, any requirement regarding, and agrees not to demand, request, plead or otherwise claim the benefit of, any marshaling, appraisement, valuation or other similar right with respect to the Collateral that may otherwise be available under applicable law or any other similar rights a junior creditor or junior secured creditor may have under applicable law.

(c) Nothing in this Agreement shall impair (i) as between the Issuer and any Secured Party, the obligations of the Issuer to such Secured Party, including the Senior Secured Claims and the Subordinated Secured Claims, or (ii) as between the Senior Secured Claimants and the Subordinated Secured Claimants, the provisions relating to the priority of payments in the Indenture; provided that it is understood that the enforcement of rights and remedies against the Collateral shall be subject to the terms of this Agreement.

SECURITY TRUST AGREEMENT

FORM OF ACCOUNT LETTER

_______________, 20__

[Name and address
of Account Bank]

[Name of the Grantor]

Ladies and Gentlemen:

Reference is made to Account No. __________ into which certain monies, instruments and other properties are deposited from time to time (the “Pledged Account”) maintained with you by ____________________ (the “Grantor”). Pursuant to the Security Trust Agreement, dated as of August 4, 2017 (as amended, supplemented or otherwise modified, the “Security Trust Agreement”), among the Grantor, other “Grantors” and Deutsche Bank Trust Company Americas, as the Security Trustee (the “Security Trustee”) and the Operating Bank. Capitalized terms used herein, unless otherwise defined herein, have the meanings assigned to them in (or by reference in) the Security Trust Agreement.

Pursuant to the Security Trust Agreement, the Grantor has granted to the Security Trustee a security interest in certain property of the Grantor, including, among other things, the following (the “Collateral”): the Pledged Account, all funds held or required by the terms of the Indenture to be held therein and all certificates and instruments, if any, from time to time representing or evidencing such Pledged Account, all notes, certificates of deposit, deposit accounts, checks and other instruments from time to time hereafter delivered to or otherwise possessed by the Security Trustee for or on behalf of such Grantor in substitution for or in addition to any or all of the then existing Collateral, and all interest, dividends, cash, instruments and other property from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the then existing Collateral, and all proceeds of any and all of the foregoing Collateral. It is a condition to the continued maintenance of the Pledged Account with you that you agree to this letter agreement.

By signing this letter agreement, you acknowledge notice of, and consent to the terms and provisions of, the Security Trust Agreement and confirm to the Security Trustee that you have received no notice of any other pledge or assignment of the Pledged Account. Further, you hereby agree with the Security Trustee that:

(a) Notwithstanding anything to the contrary in any other agreement relating to the Pledged Account, the Pledged Account is and will be subject to the terms and conditions of the Security Trust Agreement, and will henceforth be subject to written instructions only from a Responsible Officer of the Security Trustee or (unless you are otherwise notified by the Security Trustee) from

a Responsible Officer of the Administrative Agent as the agent of the Security Trustee. In the event of any conflicting instructions, those of the Security Trustee shall prevail.

(b) You will follow your usual operating procedures for the handling of any remittance received in the Pledged Account, including any remittance that contains restrictive endorsements, irregularities (such as a variance between the written and numerical amounts), undated or postdated items, missing signatures, incorrect payees, etc.

(c) You will transfer, in same day funds, on each of your business days, an amount equal to the credit balance of the Pledged Account (other than any amount required to be left on deposit for local tax or other regulatory or legal purposes) on such day to the following account (the “Collections Account”):

Deutsche Bank Trust Company Americas

[_________]

ABA: [_________]

CR: [_________]

ACCT: [_________]

REF: [_________]

SWIFT: [_________]

Each such transfer of funds shall neither comprise only part of a remittance nor reflect the rounding off of any funds so transferred.

[The foregoing clause (c) shall be revised to reflect a less frequent funds transfer permitted under the Indenture to the extent applicable for the Pledged Account.]

(d) All service charges and fees with respect to the Pledged Account shall be payable by the Grantor, and deposited checks returned for any reason shall not be charged to such account.

(e) The Security Trustee and the Administrative Agent as the agent of the Security Trustee shall be entitled to exercise any and all rights of the Grantor in respect of the Pledged Account in accordance with the terms of the Security Trust Agreement, and the undersigned shall comply in all respects with such exercise.

(f) In the event that you have or subsequently obtain by agreement, by operation of law or otherwise a security interest in the Pledged Account or any cash or other property credited thereto, such security interest shall be subordinated to the security interest of the Security Trustee.

It is the intention of the parties to grant “control” of the Pledged Account and the other Collateral to the Security Trustee for purposes of perfection of the Security Trustee’s security interest in such Collateral pursuant to Article 8 and Article 9 of the UCC.

You hereby agree (i) that your “jurisdiction” (within the meaning of Article 8 or Article 9 of the UCC, as applicable) as the securities intermediary or the bank, as applicable, with respect to each Pledged Account is the State of New York, (ii) (A) that the law of the State of New York

governs all issues specified in Article 2(1) of the Hague Convention on the Law Applicable to Certain Rights in Respect of Securities Held with an Intermediary and, to the extent not so provided in any account agreement governing the Pledged Account, such account agreement is hereby amended to so provide and (B) that you will not modify the law applicable to such issues or (so long as this letter agreement is in effect) under such account agreement, and (iii) to the extent that any Pledged Account is a “securities account” (as defined in Article 8 of the UCC), (A) you are the “securities intermediary” (as defined in Article 8 of the UCC) of such securities account, (B) all items of property credited thereto from time to time (whether cash, investment property, Permitted Account Investments, other investments, securities, instruments or other property) will be treated as a “financial asset” as defined in Article 8 of the UCC and (B) all securities, instruments and other property in order or registered from and credited to the Pledged Account shall be payable to you or to your order, or registered in your name, or shall be indorsed to you or in blank, and in no case whatsoever shall any “financial asset” as defined in Article 8 of the UCC credited to the Pledged Account be registered in the name of any Grantor, payable to or to the order of any Grantor or specially indorsed to any Grantor except to the extent the foregoing have been specially indorsed by a Grantor to you or in blank.

This letter agreement shall be binding upon you and your successors and assigns and shall inure to the benefit of the Security Trustee, the Secured Parties and their successors, transferees and assigns. You may terminate this letter agreement only upon 30 days’ prior written notice to the Grantor and the Security Trustee. Upon such termination you shall close the Pledged Account and transfer all funds in the Pledged Account to the Collections Account. After any such termination, you shall nonetheless remain obligated promptly to transfer to the Collections Account all funds and other property received in respect of the Pledged Account.

[To be inserted if Grantor is an Asset Trustee: The parties hereto agree that all of the statements, representations, covenants and agreements made by Grantor as Aircraft Trustee contained in this letter agreement and any agreement referred to herein, unless expressly otherwise stated, are made and intended only for the purpose of binding the Trust Estate (as such expression is defined in the Asset Trust Agreement) and establishing the existence of rights and remedies which can be exercised and enforced against such Trust Estate. Therefore, anything contained in this Agreement or such other agreements to the contrary notwithstanding (except for any express provisions that Asset Trustee is responsible for in its individual capacity), no recourse shall be had with respect to this letter agreement or such other agreements against Grantor in its individual capacity or against any institution or person which becomes a successor trustee or co-trustee or any officer, director, trustee, servant or direct or indirect parent or controlling person or persons of any of them.]
