          WHEREAS, the Company is currently the owner of five (5) aircraft listed in Part A of Schedule I hereto (the “Owned Aircraft”), certain of which are subject to an existing security interest, and (ii) has obtained commitments from the Manufacturer pursuant to the Aircraft Purchase Agreement for the delivery of the four Airbus A321-231 aircraft listed in Part B of Schedule I hereto (together with any aircraft substituted therefor in accordance with the Aircraft Purchase Agreement prior to the delivery thereof, the “New Aircraft” and, together with the Owned Aircraft, the “Aircraft”);

          WHEREAS, pursuant to this Agreement the Company wishes to finance (i) each Owned Aircraft after any existing security interest on such Owned Aircraft has been discharged and (ii) a portion of the purchase price of each New Aircraft;

          WHEREAS, pursuant to the Basic Pass Through Trust Agreement and each of the Trust Supplements set forth in Schedule II hereto, and concurrently with the execution and delivery of this Agreement, separate grantor trusts (collectively, the “Pass Through Trusts” and, individually, a “Pass Through Trust”) have been created to facilitate certain of the transactions contemplated hereby, including, without limitation, the issuance and sale of pass through certificates pursuant thereto (collectively, the “Certificates”) to provide for a portion of the financing of the Aircraft contemplated hereby;

          WHEREAS, the Company has entered into an underwriting agreement, dated as of June 21, 2011 (the “A and B Underwriting Agreement”) with the Underwriters named therein (the “Underwriters”), which provides that the Company will cause the Pass Through Trustee under the Class A Pass Through Trust (the “Class A Pass Through Trustee”), the Pass Through Trustee under the Class B Pass Through Trust (the “Class B Pass Through Trustee”) to issue and

          NOW, THEREFORE, in consideration of the foregoing premises and the mutual agreements herein contained and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

          SECTION 1. Financing of Aircraft. (a) The Company confirms that (i) it currently owns the Owned Aircraft and (ii) it has entered into the Aircraft Purchase Agreement with the Manufacturer pursuant to which the Company has agreed to purchase, and the Manufacturer has agreed to deliver, the New Aircraft in the months specified in Schedule I hereto, all on and subject to terms and conditions specified in the Aircraft Purchase Agreement. The Company agrees to finance the Aircraft in the manner provided herein, all on and subject to the terms and conditions hereof and of the relevant Financing Agreements.

          (b) In furtherance of the foregoing, the Company agrees to give the parties hereto, the Depositary and each of the Rating Agencies not less than two Business Days’ prior notice substantially in the form of Exhibit A hereto (a “Closing Notice”) of the scheduled closing date (the “Scheduled Closing Date”) (or, in the case of a substitute Closing Notice under Section 1(e) or (f) hereof, one Business Day’s prior notice) in respect of the financing of each Aircraft under this Agreement, which notice shall:

          (i) specify the Scheduled Closing Date of such Aircraft (which shall be a Business Day before the Cut-off Date and, except as provided in Section 1(f) hereof, the date (the “Funding Date”) on which the financing therefor in the manner provided herein shall be consummated);

          (ii) instruct each Pass Through Trustee being requested to purchase Equipment Notes pursuant to such Closing Notice (the “Applicable Pass Through Trustees”) to enter into the Participation Agreement included in the Financing Agreements with respect to such Aircraft in such form and at such a time on or before the Funding Date specified in such Closing Notice and to perform its obligations thereunder;

          (iii) instruct each of the Class A, Class B and Class C Pass Through Trustees to instruct the relevant Escrow Agent to provide a Notice of Purchase Withdrawal to the Depositary with respect to the Equipment Notes to be issued to such Pass Through Trustee in connection with the financing of such Aircraft (except in the case of any such financing on the Issuance Date); and

          (iv) specify the aggregate principal amount of each series of Equipment Notes, if any, to be issued, and purchased by the Applicable Pass Through Trustees, in connection with the financing of such Aircraft scheduled on such Funding Date (which shall in all respects comply with the Required Terms).

Notwithstanding the foregoing, in the case of any Aircraft to be financed hereunder on the Issuance Date, the Closing Notice therefor may be delivered to the parties hereto on the Issuance Date.

          (c) Upon receipt of a Closing Notice, the Applicable Pass Through Trustees shall, and shall cause the Subordination Agent to, enter into and perform their respective obligations under the Participation Agreement specified in such Closing Notice, provided that such Participation Agreement and the Trust Indenture to be entered into pursuant to such Participation Agreement shall be in the forms thereof annexed hereto in all material respects and, if modified in any material respect, as to which Rating Agency Confirmation shall have been obtained from each Rating Agency by the Company (to be delivered by the Company to the Applicable Pass Through Trustees on or before the relevant Funding Date, it being understood that if Rating Agency Confirmation shall have been received with respect to any Financing Agreements and such Financing Agreements are utilized for subsequent Aircraft (or Substitute Aircraft) without material modifications, no additional Rating Agency Confirmation shall be required); provided, however, that the relevant Financing Agreements as executed and delivered shall not vary the Required Terms. Notwithstanding the foregoing, a Trust Indenture may be modified to the extent required for the issuance of Equipment Notes pursuant to Section 4(a)(v) of this Agreement, subject to the terms of such Section and Section 9.1(c) of the Intercreditor Agreement. The Company shall pay the reasonable costs and expenses of the Rating Agencies in connection with obtaining any such Rating Agency Confirmation. With respect to each Aircraft, the Company shall cause WTC (or such other person that meets the eligibility requirements to act as indenture trustee under the Trust Indenture) to execute as Indenture Trustee the Financing Agreements relating to such Aircraft to which such Indenture Trustee is intended to be a party, and shall concurrently therewith execute such Financing Agreements to which the Company is intended to be a party and perform its respective obligations thereunder. Upon the request of either Rating Agency, the Company shall deliver or cause to be delivered to such Rating Agency a true and complete copy of each Financing Agreement relating to the financing of each Aircraft together with a true and complete set of the closing documentation (including legal opinions) delivered to the related Indenture Trustee, Subordination Agent and Pass Through Trustee under the related Participation Agreement.

          (d) The Company agrees that all Equipment Notes issued pursuant to any Trust Indenture shall initially be registered in the name of the Subordination Agent on behalf of the Applicable Pass Through Trustee.

          (e) If, after giving any Closing Notice, there shall be a delay in the delivery of the New Aircraft referred to therein, or if on the Scheduled Closing Date of the New Aircraft or Owned Aircraft referred to therein the financing thereof in the manner contemplated hereby shall not be consummated for whatever reason, the Company shall give the parties hereto and the Depositary prompt notice thereof. Concurrently with the giving of such notice of postponement or subsequently, the Company shall give the parties hereto and the Depositary a substitute Closing Notice specifying the date to which the financing of such New Aircraft (or of another New Aircraft of the same model in lieu thereof) or such Owned Aircraft shall have been re-scheduled (which shall be a Business Day before the Cut-off Date on which the Escrow Agents shall be entitled to withdraw one or more Deposits under each of the applicable Deposit Agreements to enable each of the Class A, Class B and Class C Pass Through Trustees to fund its purchase of the related Equipment Notes). Upon receipt of any such notice of postponement, each Applicable Pass Through Trustee shall comply with its obligations under Section 5.01 of each of the Trust Supplements and thereafter the financing of such New Aircraft or such Owned Aircraft, as specified in such substitute Closing Notice, shall take place on the re-scheduled

Closing Date therefor (all on and subject to the terms and conditions of the relevant Financing Agreements) unless further postponed as provided herein.

          (f) Anything in this Section 1 to the contrary notwithstanding, the Company shall have the right to accept delivery of a New Aircraft under the Aircraft Purchase Agreement on the Delivery Date thereof by utilization of bridge financing of such New Aircraft and promptly thereafter give the parties hereto and the Depositary a Closing Notice specifying a Funding Date not later than 90 days after the Delivery Date of such New Aircraft and no later than the Cut-off Date and otherwise complying with the provisions of Section 1(b) hereof. All other terms and conditions of this Note Purchase Agreement shall apply to the financing of any such New Aircraft on the re-scheduled Funding Date therefor except the related Financing Agreements shall be amended to reflect the original delivery of such New Aircraft to the Company.

          (g) If the scheduled delivery date from the Manufacturer for any New Aircraft is delayed more than 30 days beyond the last day of the month set forth opposite such New Aircraft under the heading “Scheduled Delivery Months” in Part B of Schedule I hereto, the Company may identify for delivery a substitute aircraft therefor meeting the following conditions (a “Substitute Aircraft”): (i) a Substitute Aircraft must be of the same model as the New Aircraft being replaced and (ii) the Company shall be obligated to obtain Rating Agency Confirmation in respect of the replacement of any New Aircraft by Substitute Aircraft. Upon the satisfaction of the conditions set forth above with respect to a Substitute Aircraft, the New Aircraft to be replaced shall cease to be subject to this Agreement and all rights and obligations of the parties hereto concerning such New Aircraft shall cease, and such Substitute Aircraft shall become and thereafter be subject to the terms and conditions of this Agreement to the same extent as such New Aircraft.

          (h) The Company shall have no liability for the failure of the Pass Through Trustees to purchase Equipment Notes with respect to any Aircraft or Substitute Aircraft.

          (i) Anything herein to the contrary notwithstanding, the Company shall not have the right, and shall not be entitled, at any time to request the issuance of Equipment Notes of any series to the Class A, Class B or Class C Pass Through Trustee in an aggregate principal amount in excess of the amount of the Deposits then available for withdrawal by the Escrow Agent under and in accordance with the provisions of the related Deposit Agreement.

          SECTION 2. Conditions Precedent. The obligation of the Applicable Pass Through Trustees to enter into, and to cause the Subordination Agent to enter into, any Participation Agreement as directed pursuant to a Closing Notice and to perform its obligations thereunder is subject to satisfaction of the following conditions:

          (b) the Company shall have delivered a certificate to each such Pass Through Trustee and the Liquidity Provider stating (i) that such Participation Agreement and the other Financing Agreements to be entered into pursuant to such Participation Agreement do not vary the Required Terms and (ii) that any substantive modification of such Financing Agreements

from the forms of Financing Agreements attached to this Agreement do not materially and adversely affect the Certificateholders or the Liquidity Provider, and such certification shall be true and correct.

          Anything herein to the contrary notwithstanding, the obligation of each Pass Through Trustee to purchase Equipment Notes shall terminate on the Cut-off Date.

          (v) the Company shall not (x) redeem and re-issue any Series B Equipment Notes or Series C Equipment Notes, unless it shall have obtained written confirmation from each Rating Agency that the reissuance or issuance of such Equipment Notes, as the case may be, will not result in (1) a reduction of the rating for any Class of Certificates then rated by any Rating Agency that will remain outstanding below the then current rating for such Class of Certificates or (2) a withdrawal or suspension of the rating of any Class of Certificates then rated by any Rating Agency that will remain outstanding. Any redemption or reissuance of the Series B Equipment Notes or Series C Equipment Notes shall be subject to the terms of Section 9.1(c) of the Intercreditor Agreement; and

          (vi) If (x) the Depositary’s short-term unsecured debt rating or short-term issuer credit rating, as the case may be, shall at any time fall below A-1+ from Standard & Poor’s Ratings Services or P-1 from Moody’s Investors Service, Inc. (such minimum ratings, the “Depositary Threshold Ratings”) or (y) the Company or the Depositary, in its sole discretion, gives written notice to the other of its election that the Depositary be replaced, the Company shall, within 30 days after such event occurring, cause the Depositary to be replaced with a depositary bank (a “Replacement Depositary”) on the following terms and preconditions:

          (A) the Replacement Depositary must meet the Depositary Threshold Ratings and the Company shall have obtained written confirmation from each Rating Agency that such replacement will not cause a reduction of any rating then in effect for any Class of Certificates by such Rating Agency (without regard to any downgrading of any rating of the Depositary being replaced);

          (B) the Company shall pay all fees, expenses and other amounts then owing to the replaced Depositary and, except as expressly provided in clause (C) below, the Company shall pay any up-front fee of the Replacement Depositary and (without limitation of the foregoing) all out-of-pocket expenses (including reasonable fees and expenses of legal counsel) of the parties hereto (including without limitation all amounts payable to the Rating Agencies) incurred in connection with such replacement;

          (C) solely in the case of the Depositary making an election in its discretion that it be replaced (and without limitation of clause (A) above), (x) the notice given by the Depositary to the Company shall nominate a Replacement Depositary, which shall satisfy all of terms and preconditions of this Section 4(a)(vi) (and the Company shall have the right to utilize such nominee as the Replacement Depositary or to select another Replacement Depositary), (y) the fees, expenses, indemnities and other amounts payable to the Replacement Depositary upon its execution of the Replacement Deposit Agreement or thereafter shall not to any extent exceed those which would have been payable to the Depositary had such replacement not occurred (it being specifically understood and agreed that any up-front fee of the Replacement Depositary shall be paid by the replaced Depositary, provided that, if the Company selects a Replacement Depositary other than the nominee of the replaced Depositary and the upfront fee

of such selection exceeds that of such nominee, the Company shall pay such excess), and (without limitation of the foregoing) the Depositary shall pay all out-of-pocket expenses (including reasonable fees and expenses of legal counsel) of the parties hereto (including without limitation all amounts payable to the Rating Agencies) incurred in connection with such replacement, and (z) the Replacement Depositary shall be willing to enter into a Replacement Deposit Agreement for each of the Class A, Class B and Class C Certificates with the Escrow Agent having the same terms and conditions (including without limitation as to the interest to be paid on the Deposits) as the Deposit Agreements to which the Depositary is a party; and

          (D) the Company or, in the case of the Depositary making an election that it be replaced (unless the Company shall have selected such Replacement Depositary), the Depositary, shall cause the Replacement Depositary to enter into a Replacement Deposit Agreement for each of the Class A, Class B and Class C Certificates with the Escrow Agent (and, upon request of the Company the Escrow Agent agrees to enter into any such Replacement Deposit Agreement) and shall cause the Replacement Depositary to deliver to the Company and each Rating Agency legal opinions and other closing documentation substantially similar in scope and substance as those that were delivered by the Depositary being replaced in connection with the execution and delivery of the Deposit Agreement being replaced.

          Upon satisfaction of the foregoing conditions, the Company shall instruct the Class A Pass Through Trustee, the Class B Pass Through Trustee and the Class C Pass Through Trustee, and each such Pass Through Trustee agrees, to execute and deliver to the Escrow Agent a duly completed Withdrawal Certificate (as defined in the Escrow and Paying Agent Agreements) together with a Notice of Replacement Withdrawal (as defined in the Escrow and Paying Agent Agreements).

          Each of the parties hereto agrees, at the Company’s request, to enter into any amendments to this Agreement, the Escrow and Paying Agent Agreements and any other Operative Agreements as may be necessary or desirable to give effect to the replacement of the Depositary with the Replacement Depositary and the replacement of the Deposit Agreements with the Replacement Deposit Agreements.

          Upon the execution and delivery of the Replacement Deposit Agreements, the Replacement Depositary shall be deemed to be the Depositary with all of the rights and obligations of the Depositary hereunder and under the other Operative Agreements and the Replacement Deposit Agreements shall be deemed to be the Deposit Agreements hereunder and under the other Operative Agreements, except that the obligations of the replaced Depositary under its Deposit Agreements resulting from the delivery of any Withdrawal Notice delivered thereunder shall remain in full force and effect notwithstanding the execution and delivery of the Replacement Deposit Agreements.

          (vii) Promptly after the occurrence of a Triggering Event or an Indenture Default resulting from the failure of the Company to make payments on any Equipment Note and on every Regular Distribution Date while the Triggering Event or such Indenture Default shall be continuing, the Company will, at the Subordination Agent’s request from time to time but in any event no more frequently than once every three months, provide to the Subordination Agent a statement setting forth the following information with respect to each Aircraft then subject to the

lien of a Trust Indenture: (A) whether the Aircraft are currently in service or parked in storage, (B) the maintenance status of the Aircraft and (C) the location of the Engines (as defined in the respective Trust Indentures to which such Aircraft are subject). As used in this sentence, the terms “Triggering Event”, “Indenture Default”, “Regular Distribution Date” shall have the respective meanings set forth in the Intercreditor Agreement as originally executed.

          (b) WTC, in its individual capacity, covenants with each of the other parties to this Agreement that it will, immediately upon obtaining knowledge of any facts that would cast doubt upon its continuing status as a “citizen of the United States” as defined in Section 40102(a)(15) of the Act and promptly upon public disclosure of negotiations in respect of any transaction which would or might adversely affect such status, notify in writing all parties hereto of all relevant matters in connection therewith. Upon WTC giving any such notice, WTC shall, subject to Section 9.01 of any Trust Indenture then entered into, resign as Indenture Trustee in respect of such Trust Indenture.

          SECTION 5. Notices.
