Notwithstanding the foregoing, nothing herein shall prevent the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its DTC Participants, the operation of

customary practices governing the exercise of the rights of a holder of any Class B Certificate. Upon the issuance of any Global Certificate, the Registrar or its duly appointed agent shall record a nominee of DTC as the registered holder of such Global Certificate.

(b) Transfers of any Global Certificate shall be limited to transfers of such Global Certificate in whole, but not in part, to nominees of DTC, its successor or such successor’s nominees. Beneficial interests in Global Certificates may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 4.04. Beneficial interests in Global Certificates shall be delivered to all beneficial owners thereof in the form of Definitive Certificates, if (i) DTC notifies the Trustee in writing that it is no longer willing or able to discharge properly its responsibilities as depositary for the Global Certificates, and a successor depositary is not appointed by the Trustee within 90 days of such notice, (ii) the Company, at its option, advises the Trustee in writing that it elects to terminate the book-entry system through DTC or (iii) after the occurrence and during the continuance of an Event of Default, Class B Certificateholders with Fractional Undivided Interests aggregating not less than a majority in interest in the Class B Trust advise the Trustee, the Company and DTC through DTC Participants in writing that the continuation of a book-entry system through DTC (or a successor thereto) is no longer in the Class B Certificateholders’ best interests.

None of the Company, the Registrar, the Paying Agent nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such registration instructions. Upon the issuance of Definitive Certificates, the Trustee shall recognize the Person in whose name the Definitive Certificates are registered in the Register as Certificateholders hereunder.

(e) Any Definitive Certificate delivered in exchange for an interest in a Global Certificate, pursuant to paragraph (b) of this Section 4.03 shall, except as otherwise provided by paragraph (e) of Section 4.04, bear the Restricted Legend.

(ii) If the proposed transferee is a DTC Participant and the Class B Certificate to be transferred consists of Definitive Certificates, upon receipt by the Registrar of the documents referred to in clause (i) above and instructions given in accordance with DTC’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date of such transfer and an increase in the principal amount of Global Certificates in an amount equal to the principal amount of the Definitive Certificates being transferred, and the Trustee shall cancel such Definitive Certificates so transferred.

Class B Certificate only as provided in this Trust Supplement. The Registrar shall not register a transfer of any Class B Certificate unless such transfer complies with the restrictions on transfer of such Class B Certificate set forth in this Trust Supplement. In connection with any transfer of Class B Certificates, each Class B Certificateholder agrees by its acceptance of the Class B Certificates to furnish the Registrar or the Trustee such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act and in accordance with the terms and provisions of this Article IV; provided that the Registrar shall not be required to determine the sufficiency of any such certifications, legal opinions or other information.

Until such time as no Class B Certificates remain Outstanding, the Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Section 4.04. The Trustee, if not the Registrar at such time, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, from funds then available to the Trustee, there will be distributed on each February 10 and August 10 (each, a “Regular Distribution Date”), commencing on February 10, 2008, to the Person in whose name this Certificate is registered at the close of business on the 15th day preceding the Regular Distribution Date, an amount in respect of the Scheduled Payments on the Equipment Notes due on such Regular Distribution Date, the receipt of which has been confirmed by the Trustee, equal to the product of the percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Scheduled Payments.

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 Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency of the Trustee specified in such notice.

The Certificates do not represent a direct obligation of, or an obligation guaranteed by, or an interest in, the Company, the Trustee, the Subordination Agent, any Loan Trustee or any Affiliate of any thereof. The Certificates are limited in right of payment, all as more specifically set forth on the face hereof and 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 Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of the Agreement. Each Certificateholder 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 any payment or distribution to such Certificateholder pursuant to the terms of the Agreement and that it will not have any recourse to the Company, the Trustee or the Loan Trustees except as otherwise expressly provided in the Agreement, in any Note Document or in the Intercreditor Agreement.

A copy of the Agreement may be examined during normal business hours at the principal office of the Trustee, and at such other places, if any, designated by the 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 Company and the rights of the Certificateholders under the Agreement at any time by the Company and the Trustee with the consent of the Certificateholders holding Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Trust. Any such consent by the Certificateholder of this Certificate shall be conclusive and binding on such Certificateholder and upon all future Certificateholders 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 Certificateholders of any of the Certificates.

As provided in the Agreement and subject to certain limitations set forth therein, 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 Trustee in its capacity as Registrar, or by any successor Registrar duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar, duly executed by the Certificateholder hereof or such Certificateholder’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 Trust will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in minimum denominations of [$100,000]³ [$2,000 (or such other denomination that is an integral multiple of $1,000 and, at the time of issuance, is equal to at least 1,000 euros)]⁴ Fractional Undivided Interest and multiples of $1,000 in excess thereof except that one Certificate may be issued in a different denomination. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust, as requested by the Certificateholder surrendering the same.

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

The Company, the Trustee, the Registrar and any Paying Agent shall deem and treat the person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Company, the Trustee, the Registrar or any such agent shall be affected by any notice to the contrary.

Each Certificateholder and Person with a beneficial interest herein, by its acceptance of this Certificate or such interest, agrees to treat the Trust as a grantor trust for all U.S. federal, state and local income tax purposes.

The obligations and responsibilities created by the Agreement and the 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.

Any Person acquiring or accepting this Certificate or an interest herein will, by such acquisition or acceptance, be deemed to represent and warrant to the Company, the Loan Trustees and the Trustee that either: (i) no assets of a Plan or any trust established with respect to a Plan, have been used to acquire this Certificate or an interest herein or (ii) the purchase and holding of this Certificate or interest herein by such Person are exempt from the prohibited transaction restrictions of ERISA and the Code or materially similar provisions of Similar Law pursuant to one or more prohibited transaction statutory or administrative exemptions.

THIS CERTIFICATE AND THE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES AND CERTIFICATEHOLDERS HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.
