TRUST ACCOUNTS; CONTROLLING PARTY

SECTION 2.1. Agreement to Terms of Subordination; Payments from Monies Received Only. (a) Each Trustee hereby acknowledges and agrees to the terms of subordination and distribution set forth in this Agreement in respect of each Class of Certificates and agrees to enforce such provisions and cause all payments in respect of the Equipment Notes held by the Subordination Agent to be applied in accordance with the terms of this Agreement. In addition, each Trustee hereby agrees to cause the Equipment Notes purchased by the related Trust to be registered in the name of the Subordination Agent or its nominee, as agent and trustee for such Trustee, to be held in trust by the Subordination Agent solely for the purpose of facilitating the enforcement of the subordination and other provisions of this Agreement.

(b) Except as otherwise expressly provided in the next succeeding sentence of this Section 2.1(b), all payments to be made by the Subordination Agent hereunder shall be made only from amounts received by it that constitute Scheduled Payments, Special Payments, payments under Section 8.1 of the Participation Agreements, or payments under Section 6 of the Note Purchase Agreement and only to the extent that the Subordination Agent shall have received sufficient income or proceeds therefrom to enable it to make such payments in accordance with the terms hereof. Each of the Trustees and the Subordination Agent hereby agrees and, as provided in each Trust Agreement, each Certificateholder, by its acceptance of a Certificate, has agreed to look solely to such amounts to the extent available for distribution to it as provided in this Agreement and that none of the Trustees, the Loan Trustees and the Subordination Agent is personally liable to any of them for any amounts payable or any liability under this Agreement, any Trust Agreement, or such Certificate, except (in the case of the Subordination Agent) as expressly provided herein or (in the case of the Trustees) as expressly provided in each Trust Agreement or (in the case of the Loan Trustees) as expressly provided in any Operative Agreement.

SECTION 2.2. Trust Accounts. (a) Upon the execution of this Agreement, the Subordination Agent shall establish and maintain in its name (i) the Collection Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Trustees and the Certificateholders and (ii) as a sub-account in the Collection Account, the Special Payments Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Trustees and the Certificateholders. The Special Payments Account and the Collection Account, constitute the “Trust Accounts” hereunder. Without limiting the foregoing, all monies credited to the Trust Accounts shall be, and shall remain, the property of the relevant Trust(s).

(b) Funds on deposit in the Trust Accounts shall be invested and reinvested by the Subordination Agent in Eligible Investments selected by the Subordination Agent if such investments are reasonably available and have maturities no later than the earlier of (i) 90 days following the date of such investment and (ii) the Business Day immediately preceding the Regular Distribution Date or the date of the related distribution pursuant to Section 2.4 hereof, as the case may be, next following the date of such investment; provided, however, that upon the occurrence and during the continuation of a Triggering Event, the Subordination Agent shall invest and reinvest such amounts in Eligible Investments in accordance with the written instructions of the Controlling Party. Unless otherwise expressly provided in this Agreement, any Investment Earnings shall be deposited in the Collection Account when received by the Subordination Agent and shall be applied by the Subordination Agent in the same manner as the other amounts on deposit in the Collection Account are to be applied and any losses shall be charged against the principal amount invested, in each case net of the Subordination Agent’s reasonable fees and expenses in making such investments. The Subordination Agent shall not be liable for any loss resulting from any investment, reinvestment or liquidation required to be made under this Agreement other than by reason of its willful misconduct or gross negligence (or, with respect to the handling or transfer of funds, its own negligence). Eligible Investments and any other investment required to be made hereunder shall be held to their maturities except that any such investment may be sold (without regard to its maturity) by the Subordination Agent without instructions whenever such sale is necessary to make a distribution required under this Agreement. Uninvested funds held hereunder shall not earn or accrue interest.

(c) The Subordination Agent shall possess all right, title and interest in all funds on deposit from time to time in the Trust Accounts and in all proceeds thereof (including all income thereon, except as otherwise expressly provided in Section 3.3(b) with respect to Investment Earnings). The Trust Accounts shall be held in trust by the Subordination Agent under the sole dominion and control of the Subordination Agent for the benefit of the Trustees and the Certificateholders, as the case may be. If, at any time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the Subordination Agent shall within 10 Business Days (or such longer period, not to exceed 30 calendar days, for which a Ratings Confirmation for each then rated Class of Certificates shall have been obtained) establish a new Collection Account or Special Payments Account, as the case may be, as an Eligible Deposit Account and shall transfer any cash and/or any investments to such new Collection Account or Special Payments, as the case may be. So long as WTNA is an Eligible Institution, the Trust Accounts shall be maintained with it as Eligible Deposit Accounts.

(b) The Subordination Agent shall, on each date when one or more Special Payments are made to the Subordination Agent as holder of the Equipment Notes, deposit in the Special Payments Account the aggregate amount of such Special Payments.

Such Written Notice shall also set the distribution date for such Special Payment (a “Special Distribution Date”), which shall be the Business Day which immediately follows the later to occur of (x) the 15th day after the date of such Written Notice and (y) the date the Subordination Agent has received or expects to receive such Special Payment.

If all or any portion of the Collateral is sold or otherwise disposed of following an Indenture Default, no break-up fees or other fees (excluding third-party broker fees) or similar amounts may be paid to any buyer, potential buyer or other Person from the proceeds of such sale or other disposition.

(ii) Following the occurrence and during the continuation of an Indenture Default under any Indenture, in the exercise of remedies pursuant to such Indenture, the Loan Trustee under such Indenture may be directed to lease the related Aircraft to any Person (including Sun Country) so long as the Loan Trustee in doing so acts in a “commercially reasonable” manner within the meaning of Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof).

(iii) Notwithstanding the foregoing, so long as any Certificates remain Outstanding, during the period ending on the date which is nine months after the earlier of (x) the Acceleration of the Equipment Notes issued pursuant to any Indenture and (y) the occurrence of a Bankruptcy Event, without the consent of each Trustee, no Aircraft subject to the Lien of such Indenture or such Equipment Notes may be sold if the net proceeds from such sale would be less than the Minimum Sale Price for such Aircraft or such Equipment Notes.

Thereafter, neither the Subordination Agent nor any Trustee, whether acting on instructions of the Controlling Party or otherwise, may, without the consent of each Trustee, enter into any term sheet, stipulation or other agreement (whether in the form of an adequate protection stipulation, an extension under Section 1110(b) of the Bankruptcy Code or otherwise) to effect any such restructuring proposal with or on behalf of Sun Country unless and until the material economic terms and conditions of such restructuring shall have been made available to all Certificateholders for a period of not less than 15 calendar days (except that such requirement shall not apply to any such term sheet, stipulation or other agreement that is entered into on or prior to the expiry of the 60-Day Period and that is effective for a period not longer than three months from the expiry of the 60-Day Period).

No delay or omission by any Trustee, the Controlling Party or the Subordination Agent in the exercise of any right, remedy or power or in the pursuit of any remedy shall impair any such right, power or remedy or be construed to be a waiver of any default or to be an acquiescence therein.

(iv) the Additional Certificates may be rated by one or more Rating Agencies;

(v) the Additional Certificates may allow for payment in kind of interest as “PIK Amounts” in a manner similar to the PIK Amounts in respect of the Class B Certificates;

(a) If any Trustee or the Subordination Agent receives any payment in respect of any obligations owing hereunder, which is subsequently invalidated, declared preferential, set aside and/or required to be repaid to a trustee, receiver or other party, then, to the extent of such payment, such obligations intended to be satisfied shall be revived and continue in full force and effect as if such payment had not been received.

(b) Each of the Trustees (on behalf of themselves and the holders of the Certificates) and the Subordination Agent may take any of the following actions without impairing their rights under this Agreement:

(i) obtain a Lien on any property to secure any amounts owing to it hereunder,

(ii) obtain the primary or secondary obligation of any other obligor with respect to any amounts owing to it hereunder,

(iii) renew, extend, increase, alter or exchange any amounts owing to it hereunder, or release or compromise any obligation of any obligor with respect thereto,

(iv) refrain from exercising any right or remedy, or delay in exercising such right or remedy, which it may have, or

(v) take any other action which might discharge a subordinated party or a surety under applicable law;

provided, however, that the taking of any such actions by any of the Trustees or the Subordination Agent shall not prejudice the rights or adversely affect the obligations of any other party under this Agreement.
