Any such issuance, such redemption and issuance or such payment and issuance, as applicable, shall be subject to the terms of Section 8.01(c) or 8.01(d), as applicable, of the Intercreditor Agreement. If any such new Series B Equipment Notes or Additional Series Equipment Notes or new Additional Series Equipment Notes are to be so issued, the pass through trustee of the pass through trust that acquires such new Series B Equipment Notes or Additional Series Equipment Notes or new Additional Series Equipment Notes, as applicable, shall execute and deliver an instrument (which may be, including, without limitation, a joinder agreement) by which such pass through trustee becomes a party hereto, and each of the parties hereto agrees, at the Company’s request, to enter into any amendments to (or any amendment and restatement of) this Note Purchase Agreement (including, without limitation, any modifications of the Indenture Form and the Participation Agreement Form) and any other Operative Agreements as may be necessary or desirable to give effect to such issuance, such redemption and issuance or such payment and issuance of any such new Series B Equipment Notes or Additional Series Equipment Notes or new Additional Series Equipment Notes, as applicable, and the issuance of pass through certificates by any pass through trust that acquires any such new Series B Equipment Notes or Additional Series Equipment Notes or new Additional Series Equipment Notes, as applicable, and to make changes relating to any of the foregoing (including, without limitation, to provide for any prefunding mechanism in connection therewith) and to provide for any credit support for any pass through certificates relating to any such new Series B Equipment Notes or Additional Series Equipment Notes or new Additional Series Equipment Notes (including, without limitation, to provide for payment of fees, interest, expenses, reimbursement of advances and other obligations arising from such credit support (including, without limitation, to specify such credit support as a “Liquidity Facility” and the provider of any such credit support as a “Liquidity Provider” and, if such Liquidity Facility is to be comprised of more than one instrument, to incorporate appropriate mechanics for multiple Liquidity Facilities for a single Pass Through Trust)).

(vi) Certain Reports to Subordination Agent. Promptly after the occurrence of a Triggering Event or an Indenture Event of 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 Event of Default shall be continuing, the Company shall, 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 an 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 Indentures to which such Aircraft are subject).

Upon WTC giving any such notice, WTC shall, subject to Section 8.01 of any Indenture then entered into, resign as Loan Trustee in respect of such Indenture.

(ii) Situs of Activity. Except with the consent of the Company, which shall not be unreasonably withheld, WTC will act as Pass Through Trustee and Subordination Agent solely through its offices within the State of Delaware, except for such services as may be performed for it by independent agents in the ordinary course of business, but not directly by it, in other states.
