        MBIA Insurance Corporation (the "Insurer") has issued a Note Guaranty Insurance
Policy (the "Policy") relating to the Obligations containing the following provisions, the
Policy being on file at the Corporate Trust Office of the Indenture Trustee.

        The Insurer, in consideration of the payment of the premium and subject to the terms
of the Policy, thereby unconditionally and irrevocably guarantees to any Owner that an
amount equal to each full and complete Insured Amount will be received from the Insurer by
LaSalle Bank National Association, or its successors, as indenture trustee for the Owners
(the "Indenture Trustee"), on behalf of the Owners, for distribution by the Indenture
Trustee to each Owner of each Owner's proportionate share of the Insured Amount.  The
Insurer's obligations under the Policy with respect to a particular Insured Amount shall be
discharged to the extent funds equal to the applicable Insured Amount are received by the
Indenture Trustee, whether or not those funds are properly applied by the Indenture
Trustee.  Insured Amounts will be made only at the time set forth in the Policy, and no
accelerated Insured Amounts will be made regardless of any acceleration of the Obligations,
unless the acceleration is at the sole option of the Insurer.

        Notwithstanding the foregoing, the Policy does not cover shortfalls, if any,
attributable to the liability of the Issuer or the Indenture Trustee for withholding taxes,
if any (including interest and penalties in respect of any such liability).

        The Insurer will pay any Insured Amount that is a Preference Amount on the Business
Day following receipt on a Business Day by the Fiscal Agent (as described below) of (a) a
certified copy of the order requiring the return of a preference payment, (b) an opinion of
counsel satisfactory to the Insurer that such order is final and not subject to appeal,
(c) an assignment in such form as is reasonably required by the Insurer, irrevocably
assigning to the Insurer all rights and claims of the Owner relating to or arising under the
Obligations against the debtor which made such preference payment or otherwise with respect
to such preference payment and (d) appropriate instruments to effect the appointment of the
Insurer as agent for such Owner in any legal proceeding related to such preference payment,
such instruments being in a form satisfactory to the Insurer, provided that if such
documents are received after 12:00 noon, New York City time, on such Business Day, they will
be deemed to be received on the following Business Day.  Such payments shall be disbursed to
the receiver or trustee in bankruptcy named in the final order of the court exercising
jurisdiction on behalf of the Owner and not to any Owner directly unless such Owner has
returned principal or interest paid on the Obligations to such receiver or trustee in
bankruptcy, in which case such payment shall be disbursed to such Owner.

        The Insurer will pay any other amount payable under the Policy no later than
12:00 noon, New York City time, on the later of the Payment Date on which the related
Deficiency Amount is due or the second Business Day following receipt in New York, New York
on a Business Day by U.S. Bank Trust National Association, as Fiscal Agent for the Insurer,
or any successor fiscal agent appointed by the Insurer (the "Fiscal Agent"), of a Notice (as
described below), provided that if such Notice is received after 12:00 noon, New York City
time, on such Business Day, it will be deemed to be received on the following Business Day.
If any such Notice received by the Fiscal Agent is not in proper form or is otherwise
insufficient for the purpose of making claim under the Policy, it shall be deemed not to
have been received by the Fiscal Agent for purposes of this paragraph, and the Insurer or
the Fiscal Agent, as the case may be, shall promptly so advise the Indenture Trustee and the
Indenture Trustee may submit an amended Notice.

        Insured Amounts due under the Policy, unless otherwise stated in the Policy, will be
disbursed by the Fiscal Agent to the Indenture Trustee on behalf of the Owners by wire
transfer of immediately available funds in the amount of the Insured Amount less, in respect
of Insured Amounts related to Preference Amounts, any amount held by the Indenture Trustee
for the payment of such Insured Amount and legally available therefor.

        The Fiscal Agent is the agent of the Insurer only, and the Fiscal Agent shall in no
event be liable to Owners for any acts of the Fiscal Agent or any failure of the Insurer to
deposit, or cause to be deposited, sufficient funds to make payments due under the Policy.

        Subject to the terms of the Agreement, the Insurer shall be subrogated to the rights
of each Owner to receive payments under the Obligations to the extent of any payment by the
Insurer under the Policy.
