WHEREAS, on December 13, 2012, the Company caused the Class A Pass Through Trustee and the Class B Pass Through Trustee to issue and sell an aggregate principal amount of $546,184,000 of Class A Certificates and Class B Certificates. The proceeds from the sale of the Class A Certificates and Class B Certificates were deposited with the Class A Depositary and Class B Depositary, respectively, in accordance with the Class A/B Note Purchase Agreement, the Class A Deposit Agreement and the Class B Deposit Agreement and a portion of such Deposits has been used by the Class A Pass Through Trustee and the Class B Pass Through Trustee to purchase Series A Equipment Notes and Series B Equipment Notes, respectively, issued by the Company and secured by the Owned Aircraft (as defined below) (the “Prior Series”).

WHEREAS, the agreements relating to the Class A Certificates and Class B Certificates permit the Company to issue Series C Equipment Notes secured by the Aircraft but subordinated to the Series A Equipment Notes and the Series B Equipment Notes, subject to the terms and conditions of the Trust Indentures and the Intercreditor Agreement, and the Company now wishes to issue and sell such Series C Equipment Notes;

WHEREAS, the Company (i) is currently the owner of the aircraft listed in Part A of Schedule I hereto (the “Owned Aircraft”), which are subject to an existing security interest in favor of the Indenture Trustee under the applicable Indentures, and (ii) has obtained commitments from the Manufacturer pursuant to the Aircraft Purchase Agreement for the delivery of the 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”);

WHEREAS, as required by the Underwriting Agreement and the Note Purchase Agreement dated December 13, 2012 relating to the Class A Certificates and the Class B Certificates, the Company has obtained written confirmation from the Rating Agencies that the terms of the Class C Certificates will not result in a withdrawal, suspension or downgrading of the ratings of the Class A Certificates or Class B Certificates; and

WHEREAS, pursuant to the terms of the Class C Pass Through Trust Agreement and this Agreement, on the date of this Agreement the Class C Pass Through Trustee will purchase, and the Company will issue and sell, the Series C Equipment Notes in the respective principal amounts listed in Schedule I hereto, which shall be secured by the related Aircraft set forth in such Schedule.

WHEREAS, concurrently with the execution and delivery of this Agreement, (i) the Escrow Agent and the Depositary have entered into the Deposit Agreement, dated as of the date hereof (the “Class C Deposit Agreement,” together with the Class A Deposit Agreement and Class B Deposit Agreement, the “Deposit Agreements”), whereby the Escrow Agent agreed to direct the Underwriter to make certain deposits referred to therein on the Issuance Date in the

(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 1A(e) or (f) hereof, one Business Day’s prior notice) in respect of the financing of each New Aircraft under this Agreement, which notice shall:

(i) specify the Scheduled Closing Date of such New Aircraft (which shall be a Business Day before the Cut-off Date and, except as provided in Section 1A(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 New 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;

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.

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) 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, 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 1A 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

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 New Aircraft or Substitute Aircraft.

(i) Anything herein to the contrary notwithstanding, and except for any Equipment Notes purchased on the Issuance Date, 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 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.

Upon satisfaction of the foregoing conditions, the Company shall instruct 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).
