The Exchange Offer shall expire at 5:00 p.m., New York City time, on , 2001 or on such later date or time to which Airplanes Group may extend the Exchange Offer (the "Expiration Date"). Subject to the terms and conditions set forth in the Prospectus, Airplanes Group expressly reserves the right to extend the Exchange Offer at any time and from time to time by giving oral (confirmed in writing) or written notice to you before 9:00 A.M., New York City time, on the business day following the previously scheduled Expiration Date.

Airplanes Group will give oral (confirmed in writing) or written notice of any amendment, modification, withdrawal, termination or nonacceptance to you as promptly as practicable. In carrying out your duties as Exchange Agent, you are to act in accordance with the following Instructions: 1. You will perform such duties and only such duties as are set forth in (i) the section of the Prospectus captioned "The Exchange Offer", (ii) the Letter of Transmittal and Notice of Guaranteed Delivery to be distributed to holders of Old Certificates (together, "Other Exchange Materials"), and (iii) this Agreement, and all other actions reasonably necessary in connection therewith; provided, however, that in no way will your general duty to act in good faith be discharged by the foregoing. 2. You will establish an account with respect to the Old Certificates at The Depository Trust Company (the "Book-Entry Transfer Facility") for purposes of the Exchange Offer within two business days after the date of the Prospectus, and any financial institution that is a participant in the Book-Entry Transfer Facility's systems may make book-entry delivery of the Old Certificates by causing the Book-Entry Transfer Facility to transfer 2 such Old Certificates into your account in accordance with the Book-Entry Transfer Facility's procedure for such transfer. 3. You are to examine each of the Letters of Transmittal and certificates for Old Certificates (or confirmation of book-entry transfer into your account at the Book-Entry Transfer Facility) and any other documents delivered or mailed to you by or for holders of the Old Certificates to ascertain whether: (i) the Letters of Transmittal and any such other documents are duly executed and properly completed in accordance with instructions set forth therein and (ii) the Old Certificates have otherwise been properly and validly tendered. In each case where the Letter of Transmittal or any other document has been improperly completed or executed or any of the certificates for Old Certificates are not in proper form for transfer or some other irregularity in connection with the acceptance of such securities in the Exchange Offer exists, you will endeavor promptly to inform the presenters of the need for fulfillment of all requirements and to take any other action as may be necessary or advisable to cause such irregularity to be corrected. 4. With the approval of any Director of Airplanes Limited or any Controlling Trustee of Airplanes U.S. Trust (such approval, if given orally, to be confirmed in writing) or any other party designated by a Director of Airplanes Limited or Controlling Trustee of Airplanes U.S. Trust in writing, you are authorized to waive any irregularities in connection with any tender of Old Certificates pursuant to the Exchange Offer. 5. Tenders of Old Certificates may be made only as set forth in the Other Exchange Materials and in the section of the Prospectus captioned "The Exchange Offer -- Procedures for Tendering Old Certificates", and Old Certificates shall be considered properly and validly tendered to you only when tendered in accordance with the procedures set forth therein. Notwithstanding the provisions of this paragraph 5, Old Certificates which the Administrative Agent shall approve as having been properly and validly tendered shall be considered to be properly and validly tendered (such approval, if given orally, shall be confirmed in writing). 6.

Delivery of New Certificates will be made on behalf of Airplanes Group by you in an aggregate principal amount of New Certificates equal to the aggregate principal amount of Old Certificates validly tendered; provided, however, that in all cases, Old Certificates tendered pursuant to the Exchange Offer will be exchanged only after timely receipt by you of certificates for such Old Certificates (or confirmation of book-entry transfer into your account at the Book-Entry Transfer Facility), a properly completed and duly executed Letter of Transmittal (or facsimile thereof) with any required signature guarantees and any other required documents. 9. Tenders pursuant to the Exchange Offer may be withdrawn at any time prior to the Expiration Date. 10. Airplanes Group shall not be required to accept for exchange any Old Certificates tendered. Unless notice by Airplanes Group not to exchange any Old Certificates tendered shall be given (and confirmed in writing) by Airplanes Group to you, such Old Certificates properly tendered shall be accepted. 11.
