         The Holder of this Subclass A-9 Note agrees, by acceptance hereof, to
pay over to the Cash Manager any money (including principal, Premium and
interest) paid to it in respect of this Subclass A-9 Note in the event that the
Cash Manager, acting in good faith, determines subsequently that such monies
were not paid in accordance with the priority of payment provisions of the
Indenture or as a result of any other mistake of fact or law on the part of the
Cash Manager in making such payment.

         As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Subclass A-9 Note may be registered on the
register maintained by the Indenture Trustee for the purpose of registering
transfers and exchanges upon surrender of this Subclass A-9 Note for
registration of transfer at the office or agency designated by the Issuer
pursuant to the Indenture, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Indenture Trustee duly
executed by, the Holder hereof or his attorney duly authorized in writing, with
such signature guaranteed, and such other documents as the Indenture Trustee may
require, and thereupon one or more new Subclass A-9 Notes of authorized
denominations and in the same aggregate principal amount will be issued to the
designated transferee or transferees. No service charge will be charged for any
registration of transfer or exchange of this Subclass A-9 Note, but the
transferor may be required to pay a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any such registration
of transfer or exchange.

         Prior to the due presentment for registration of transfer of this
Subclass A-9 Note, the Issuer, the Indenture Trustee and any agent of the Issuer
or the Indenture Trustee may deem and treat the Person in whose name this
Subclass A-9 Note (as of the day of determination or as of such other date as
may be specified in the Indenture) is registered as the absolute owner and
Holder hereof for the purpose of receiving payment of all amounts payable with
respect to this Subclass A-9 Note and for all other purposes, and neither the
Issuer, the Indenture Trustee nor any such agent shall be affected by notice to
the contrary.

         The Indenture permits the amendment or modification of the Indenture
and the Subclass A-9 Notes by the Issuer with the consent of the Holders of a
majority of the Outstanding Principal Balance of all Notes on the date of any
vote of such Holders (voting as a single class); provided that, without the
consent of each Holder of any class or subclass of



                                       9

   10



Notes then Outstanding, no such amendment may (i) modify the provisions of the
Indenture, the Notes or the Cash Management Agreement setting forth the
frequency or the currency of payment of, the maturity of, or the method of
calculation of the amount of, any interest, principal and Premium, if any,
payable in respect of such class or subclass of Notes, (ii) modify the
provisions of Section 5.02 of the Indenture relating to the sale of any assets
of the Issuer, (iii) reduce the percentage of the aggregate Outstanding
Principal Balance of such class or subclass of Notes required to approve any
amendment or waiver of Section 9.01 of the Indenture or (iv) alter the manner or
priority of payment of any class or subclass of Notes or the priority of payment
of the Expenses, the Swap Payments or the Swap Breakage Costs (each, a "Basic
Terms Modification"). Any such amendment or modification shall be binding on
every Holder hereof, whether or not notation thereof is made upon this Subclass
A-9 Note. The Indenture also permits the Indenture Trustee to agree, without the
consent of any Noteholder, (a) to any modification (other than a Basic Terms
Modification) of, or the waiver or authorization of any breach or prospective
breach of, any provision of any Related Document or of the relevant Notes to
correct a manifest error or an error which is of a formal, minor or technical
nature or (b) to modify the provisions of the Indenture or the Cash Management
Agreement relating to the timing of movement of Rental Payments or other monies
received or Expenses incurred among the Accounts by the Cash Manager.

         The subordination provisions contained in Section 3.08, Section 3.09
and Article X of the Indenture may not be amended or modified without the
consent of each Noteholder of the class or subclass affected thereby and each
Noteholder of any class or subclass of Notes ranking senior thereto. In no event
shall the provisions set forth in Section 3.08 of the Indenture relating to the
priority of the Expenses, Swap Payments and Swap Breakage Costs be amended or
modified.

         The Indenture also contains provisions permitting the Holders of Notes
representing a majority of the Outstanding Principal Balance of the Senior Class
of Notes, on behalf of the Holders of all of the Subclass A-9 Notes, to waive
compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver shall be conclusive and binding upon all present and future Holders of
this Subclass A-9 Note and of any Subclass A-9 Note issued upon the registration
of transfer of, in exchange or in lieu of or upon the refinancing of this
Subclass A-9 Note, whether or not notation of such consent or waiver is made
upon this Subclass A-9 Note.

         The term "Issuer" as used in this Subclass A-9 Note includes any
successor to the Issuer under the Indenture.

         The Issuer is permitted by the Indenture, under certain circumstances,
to merge or consolidate, subject to the rights of the Indenture Trustee and the
Holders of Subclass A-9 Notes under the Indenture.

         The Subclass A-9 Notes are issuable only in registered form in
denominations as provided in the Indenture, subject to certain limitations
therein set forth.

         This Subclass A-9 Note shall in all respects be governed by, and
construed in accordance with, the laws of the State of New York, including all
matters of construction, validity and performance.
