Except as otherwise provided in the Agreement and notwithstanding the above, the final distribution on this Certificate will be made after notice mailed by the Pass Through Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency of the Pass Through Trustee specified in such notice.

[Reverse Of Certificate]

                                This Certificate does not represent a direct obligation of, or an obligation guaranteed by, or an interest in, the Lessee, the Guarantor, any Owner Lessor, any Owner Participant or the Pass Through Trustee or any affiliate thereof. The Certificates are limited in right of payment, all as more specifically set forth in the Agreement. All payments or distributions made to Certificateholders under the Agreement shall be made only from the Trust Property and only to the extent that the Pass Through Trustee shall have received sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of the Agreement. Each Holder of this Certificate, by its acceptance hereof, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for distribution to such Holder as provided in the Agreement. This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for information with respect to the interests, rights, benefits, obligations, proceeds and duties evidenced hereby. A copy of the Agreement may be examined during normal business hours at the principal office of the Pass Through Trustee, and at such other places, if any, designated by the Pass Through Trustee, by any Certificateholder upon request.

                                The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Lessee and the Guarantor and the rights of the Certificateholders under the Agreement at any time by the Lessee, the Guarantor and the Pass Through Trustee with the consent of the Holders of Certificates evidencing Fractional Undivided Interests aggregating a majority in interest of the Fractional Undivided Interests evidenced by all Certificates at the time Outstanding (as determined pursuant to the terms of such Agreement). Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

                                As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Register upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Pass Through Trustee in its capacity as Registrar, or by any successor Registrar, in the Borough of Manhattan, The City of New York, duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Pass Through Trustee and the Registrar duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Pass Through Trust will be issued to the designated transferee or transferees.

                                The Certificates are issuable only as registered Certificates without coupons in minimum denominations of $2,000 and any integral multiples of $1,000 in excess thereof. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Pass Through Trust, as requested by the Holder surrendering the same.

                                No service charge will be made for any such registration of transfer or exchange, but the Pass Through Trustee shall require payment of an amount sufficient to cover any tax or charge payable in connection therewith.

                                The Pass Through Trustee, the Lessee, the Guarantor, the Owner Lessors, the Registrar and any agent of the Pass Through Trustee or the Registrar shall treat the person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Pass Through Trustee, the Lessee, the Guarantor, the Owner Lessors, the Registrar or any such agent shall be affected by any notice to the contrary.

                                The obligations and responsibilities created by the Agreement and the Pass Through Trust created thereby shall terminate upon the distribution to Certificateholders of all amounts required to be distributed to them pursuant to the Agreement and the disposition of all property held as part of the Trust Property.
