       (as defined in the attached endorsement)


AMBAC ASSURANCE CORPORATION (AMBAC), a Wisconsin stock insurance corporation, in
consideration of the payment of the premium and subject to the terms of this
Policy, hereby agrees unconditionally and irrevocably to pay to the Trustee for
the benefit of the Holders of the Insured Obligations, that portion of the
Insured Amounts which shall become Due for Payment but shall be unpaid by reason
of Nonpayment.


Ambac will make such payments to the Trustee from its own funds on the later of
(a) one (1) Business Day following notification to Ambac of Nonpayment or (b)
the Business Day on which the Insured Amounts are Due for Payment. Such payments
of principal or interest shall be made only upon presentation of an instrument
of assignment in form and substance satisfactory to Ambac, transferring to Ambac
all rights under such Insured Obligations to receive the principal of and
interest on the Insured Obligation. Ambac shall be subrogated to all the
Holders' rights to payment on the Insured Obligations to the extent of the
insurance disbursements so made. Once payments of the Insured Amounts have been
made to the Trustee, Ambac shall have no further obligation hereunder in respect
of such Insured Amounts.


In the event the Trustee for the Insured Obligations has notice that any payment
of principal or interest on an Insured Obligation which has become Due for
Payment and which is made to a Holder by or on behalf of the Trustee has been
deemed a preferential transfer and theretofore recovered from its Holder
pursuant to the United States Bankruptcy Code in accordance with a final,
nonappealable order of a court of competent jurisdiction, such Holder will be
entitled to payment from Ambac to the extent of such recovery if sufficient
funds are not otherwise available.


This Policy is noncancelable by Ambac for any reason, including failure to
receive payment of any premium due hereunder. The premium on this Policy is not
refundable for any reason. This Policy does not insure against loss of any
prepayment or other acceleration payment which at any time may become due in
respect of any Insured Obligation, other than at the sole option of Ambac, nor
against any risk other than Nonpayment, including failure of the Trustee to make
any payment due Holders of Insured Amounts.


To the fullest extent permitted by applicable law, Ambac hereby waives and
agrees not to assert any and all rights and defenses, to the extent such rights
and defenses may be available to Ambac, to avoid payment of its obligations
under this Policy in accordance with the express provisions hereof.


Any capitalized terms not defined herein shall have the meaning given such terms
in the endorsement attached hereto or in the Agreement.


In witness whereof, Ambac has caused this Policy to be affixed with its
corporate seal and to be signed by its duly authorized officers in facsimile to
become effective as their original signatures and binding upon Ambac by virtue
of the countersignature of its duly authorized representative.

<PAGE>

      Notwithstanding the first sentence of the second paragraph of the face of
this Policy, the Insurer will pay any Insured Amount payable hereunder no later
than 4:00 p.m. (New York City time) to the Subordination Agent (or, with respect

form or is otherwise insufficient for the purpose of making a claim under the
Policy, it shall be deemed not to have been received for purposes of this
paragraph, and the Insurer shall promptly so advise the Subordination Agent (or
the Class G-1 Primary Liquidity Provider, if applicable) and the Subordination
Agent (or the Class G-1 Primary Liquidity Provider, if applicable) may submit an
amended Notice of Nonpayment.

      Notwithstanding the third paragraph of the face of this Policy, the
Insurer shall pay any Preference Amount due to be paid pursuant to an Order, no
later than 4:00 p.m. on the earlier of (x) the Special Distribution Date
established for the payment of such Preference Amount (or, if payment is to be
made to a receiver, conservator, debtor-in-possession or trustee in bankruptcy,
as directed by the Subordination Agent on the date specified in the Order or in
the absence thereof, in the request therefor) and (y) the third Business Day
after the date of the expiration of this Policy, but in any event no earlier
than the third Business Day following receipt by the Insurer on a Business Day
of (i) a certified copy of an Order, (ii) a certificate by or on behalf of the
Subordination Agent, the Class G-1 Trustee or the Holder that such Order has
been entered and is not subject to any stay, (iii) an assignment, in form and
substance satisfactory to the Insurer, duly executed and delivered by the
Subordination Agent, the Class G-1 Trustee or the Holder, irrevocably assigning
to the Insurer all rights and claims of the Subordination Agent, the Class G-1
Trustee or the Holder (provided such Preference Amount is received by the
Holder) with respect to such Preference Amount and (iv) a Notice of Avoided
Payment (in the form attached hereto as Exhibit B) appropriately completed and

deemed to have been received on the next Business Day. If any Notice of Avoided
Payment is not in proper form or is otherwise insufficient for the purpose of
making a claim under the Policy, it shall be deemed not to have been received
for purposes of this paragraph and the Insurer shall promptly so advise the
Subordination Agent and the Subordination Agent may submit an amended Notice of
Avoided Payment. Such payment shall be disbursed to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order, and not to the

Subordination Agent, the Class G-1 Trustee or the Holder has made a payment of
the Preference Amount to the court or such receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order, in which case
the Insurer will pay to the Subordination Agent for payment over to the Holder
or the Class G-1 Trustee, subject to the delivery of (a) the items referred to
in clauses (i), (ii), (iii) and (iv) above to the Insurer and (b) evidence
satisfactory to the Insurer that payment has been made to such court or
receiver, conservator, debtor-in-possession or trustee in bankruptcy named in
the Order.

      No instrument of assignment shall be required notwithstanding the second
paragraph of the face of this Policy except in connection with payment of a

<PAGE>

Preference Amount. Notwithstanding the second paragraph of the face of this
Policy, the Insurer shall not be subrogated to the Class G-1 Certificates, and
shall be subrogated to the Series G-1 Equipment Notes only to the extent
provided in the Agreement. For the avoidance of doubt, the subrogation
provisions in the Agreement include Sections 2.4, 3.2 and 3.3 thereof.

      A premium will be payable on this Policy in accordance with the terms of
the Insurance Agreement.

      The face of the Policy to which this Endorsement is attached and of which
it forms a part is hereby amended to provide that the Insurer shall have no
obligation (i) to pay any Insured Amount or Preference Amount except at the
times and in the amounts expressly provided for in this Policy or (ii) to pay
any amount in excess of $134,644,000, plus interest at the applicable Stated
Interest Rate for the Class G-1 Certificates for the period during which the
Class G-1 Certificates were outstanding plus Excess Interest. Clause (ii) of the
preceding sentence shall not limit the Insurer's payment obligations with
respect to any Deficiency Amount paid by the Insurer which becomes a Preference
Amount. This Policy does not cover (i) premiums (including, without limitation,
Premium), if any, payable in respect of the Class G-1 Certificates or the Class
G-1 Escrow Receipts, (ii) shortfalls, if any, attributable to the liability of
the Subordination Agent, the Class G-1 Trust or the Class G-1 Trustee for
withholding taxes, if any (including interest and penalties in respect of any
such liability) or (iii) any risk other than the risk of Nonpayment and the risk
of the occurrence of a Preference Amount, including failure of the Subordination
Agent or the Class G-1 Trustee to make any payment due to the Holders of the
Class G-1 Certificates from funds received.

      This Policy and the obligations of the Insurer hereunder shall terminate
on the day (the "Termination Date") which is one year and one day following the
Distribution Date upon which the Final Distributions on the Class G-1
Certificates are made. The foregoing notwithstanding, if an Insolvency
Proceeding has commenced and has not been concluded or dismissed on the
Termination Date, then this Policy and the Insurer's obligations hereunder shall
terminate on the later of (i) the date of the conclusion or dismissal of such
Insolvency Proceeding without continuing jurisdiction by the court in such
Insolvency Proceeding, and (ii) the date on which the Insurer has made all
payments required to be made under the terms of this Policy in respect of
Preference Amounts.

      Nothing herein contained shall be held to vary, alter, waive or extend any
of the terms, conditions, provisions, agreements or limitations of the
above-mentioned Policy other than as specifically provided for otherwise by this
Endorsement.

      The obligations of the Insurer to make payments to the Class G-1 Primary
Liquidity Provider hereunder may not be amended or modified without the consent
of the Class G-1 Primary Liquidity Provider.

      This Policy is issued under and pursuant to, and shall be construed under,
the laws of the State of New York.
