or (ii) the Series 2005-2 Note Interest Payment for any Series 2005-2 Note on
any Payment Date, or (iii) any other amount due under this Supplement on the
date when due, then, in each case, the Issuer shall, from time to time, pay
interest on such unpaid amounts, to the extent permitted by Applicable Law, to,
but not including, the date of actual payment (after as well as before
judgment), at a rate per annum equal to the Overdue Rate, for the period during
which such principal, interest or other amount shall be unpaid from the due
date of such payment to the date of actual payment thereof.  Default Fees shall be distributed from the
Series 2005-2 Series Account at the times and subject to the priorities set

respect to a Series 2005-2 Note exceed the maximum amount permitted by

rate permitted by Applicable Law, the rate of interest to accrue pursuant to
this Supplement and such Series 2005-2 Note shall be limited to the maximum
rate permitted by Applicable Law, but any subsequent reductions in the
Alternative Rate shall not reduce the interest to accrue on such Series 2005-2
Note below the maximum amount permitted by Applicable Law until the total
amount of interest accrued on such Series 2005-2 Note equals the amount of interest
that would have accrued if a varying rate per annum equal to the interest rate
had at all times been in effect.  If the
total amount of interest paid or accrued on the Series 2005-2 Note under the
foregoing provisions is less than the total amount of interest that would have
accrued if the interest rate had at all times been in effect, the Issuer agrees
to pay to the Series 2005-2 Noteholders an amount equal to the difference
between (a) the lesser of (i) the amount of interest that would have accrued if
the maximum rate permitted by Applicable Law had at all times been in effect,
or (ii) the amount of interest that would have accrued if the interest rate had
at all times been in effect, and (b) the amount of interest accrued in
accordance with the other provisions of this Supplement.  Section 204.           Principal Payments on the Series
2005-2 Notes.  (a) The unpaid
principal balance of the Series 2005-2 Notes shall be payable on each Payment

Principal Payment Amount for such Payment Date, the Scheduled Principal Payment
Amount for such Payment Date and that portion of the Supplemental Principal

accordance with Section 302 of this Supplement.  (f)            On or before the date it acquires a

for such demand), the Issuer shall pay directly to such Affected Party such
additional amount or amounts as will compensate such Affected Party for such
additional or increased cost incurred or such reduction suffered.  (b)           If either (i) the introduction of or
any change in or in the interpretation of any law, guideline, rule, regulation,
directive or request or (ii) compliance by any Affected Party with any law,

have the effect of reducing the rate of return on the capital of any Affected
Party as a consequence of its obligations hereunder or under the other Related
Documents or arising in connection herewith or therewith to a level below that
which any such Affected Party could have achieved but for such introduction,
change or compliance (taking into consideration the policies of such Affected
Party with respect to capital adequacy) by an amount deemed by such Affected
Party to be material, then from time to time, within ten (10) days after demand
by such Affected Party (which demand shall be accompanied by a statement
setting forth the basis for such demand), the Issuer shall pay directly to such
Affected Party such additional amount or amounts as will compensate such
Affected Party for such reduction.  (c)           If as a result of any event or
circumstance similar to those described in clauses (a) or (b) of this Section,
any Affected Party is required to compensate a bank or other financial
institution providing liquidity support, credit enhancement or other similar
support to such Affected Party in connection with this Agreement or the funding
or maintenance of Series 2005-2 Advances hereunder, then within ten (10) days
after demand by such Affected Party, the Issuer shall pay to such Affected
Party such additional amount or amounts as may be necessary to reimburse such
Affected Party for any amounts payable or paid by it.  (d)           In determining any amount provided
for in this section, the Affected Party may use any reasonable averaging and
attribution methods.  Any Affected Party
making a claim under this section shall submit to the Issuer and the Manager a
written description as to such additional or increased cost or reduction and
the calculation thereof, which written description shall be conclusive absent
demonstrable error.  (e)           If a Liquidity Bank shall notify the
Deal Agent that a Eurodollar Disruption Event as described in clause (a) of the
definition of Eurodollar Disruption Event has occurred, the Deal Agent shall
in turn so notify the Issuer, whereupon all Series 2005-2 Advances in respect
of which Series 2005-2 Note Interest Payment accrues at the Adjusted Eurodollar
Rate shall immediately be converted into a Series 2005-2 Advance in respect of
which interest accrues at the Base Rate.  (f)            Any amounts payable by the Issuer
pursuant to this Section 207 are contingent upon the availability of funds to
make such payment in accordance with the provisions of Section 302 hereof and,
to the extent such funds are not available, shall not constitute a Claim (as
defined in Section 101(5) of the Bankruptcy Code) against the Issuer in any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
involving the Issuer in the event that such amounts are not paid in accordance
with Section 302 of this Supplement.  16

Exhibit A to the Policy and submit such claim for such Insured Amount to the

The Issuer hereby agrees for the benefit of the Series Enhancer (and
each Series 2005-2 Noteholder, by acceptance of its Series 2005-2 Notes, will
be deemed to have agreed) that, without limiting any other rights of the Series
Enhancer, to the extent the Series Enhancer pays, or causes payment of, Insured
Amounts, either directly or indirectly (as by paying through distribution to
the Indenture Trustee), to the Series 2005-2 Noteholders, the Series Enhancer
will be entitled to (x) reimbursement of such amounts from amounts on deposit

knowledge that a Deficiency Amount will exist on the applicable Payment Date,
the Indenture Trustee shall promptly notify the Series Enhancer, and each

the Issuer with respect to the Series 2005-2 Notes, shall not discharge the

rights as subrogee upon the register of the Series 2005-2 Noteholders upon
receipt from the Series Enhancer of proof of payment by the Series Enhancer of

such amounts.  (g)Each
of the Issuer and the Indenture Trustee hereby grants to the Series Enhancer,
as long as no Series Enhancer Default exists, the right of prior approval of
amendments, waivers or supplements to the Related Documents available to Series

Noteholder will be entitled to payment thereof pursuant to the terms of the
Policy.  The Indenture Trustee shall
furnish to the Series Enhancer, at its written request, the requested records
it holds in its possession evidencing the payments of principal of and interest
on the Series 2005-2 Notes, if any, which have been made by the Indenture
Trustee and subsequently recovered from Series 2005-2 Noteholders, and the
dates on which such payments were made.  Without limiting any rights of
the Series Enhancer under the Policy or any other Related Document, and without
modifying or otherwise affecting any terms or conditions of the  Policy, each Series 2005-2 Noteholder, by its
acceptance of a Series 2005-2 Note, and the Indenture Trustee hereby agree that
the Series Enhancer (so long as no Series Enhancer Default exists) may at any
time during the continuation of any Proceeding relating to a Preference Amount
direct all matters relating to such Preference Amount, including, without
limitation, (i) the direction of any appeal of any order relating to any
Preference Amount and (ii) the posting of any surety, supersedeas or
performance bond pending any such appeal. 
In addition, and without limitation of the foregoing, the Series
Enhancer shall be subrogated to the rights of the Indenture Trustee and each
such Series 2005-2 Noteholder in the conduct of any Proceeding with respect to
any such Preference Amount, including, without limitation, all rights of any
party to an adversary proceeding action with respect to any order issued in
connection with any such Preference Amount. 
Insured Amounts paid by the Series Enhancer to the Indenture Trustee
shall be received by the Indenture Trustee, as agent to the Series 2005-2
Noteholders, and deposited into the Series Account for distribution in
accordance with Section 302 hereof.  Each
Series 2005-2 Noteholder by its acceptance of a Series 2005-2 Note, and the
Indenture Trustee, as agent to the Series 2005-2 Noteholders, hereby
acknowledges and affirms that the rights of the Series 2005-2 Noteholders to
any moneys paid or payable in respect of the Series 2005-2 Notes shall be fully
subrogated to the Series Enhancer to the extent of any payment made by the
Series Enhancer pursuant to the terms of the Policy, and any interest due
thereon.  (j)By
acceptance of a Series 2005-2 Note, each Series 2005-2 Noteholder agrees to be
bound by the terms of the Policy, including, without limitation, the method and
timing of payment, the Series Enhancers right of subrogation and the other
rights of the Series Enhancer set forth therein.  (k)Notwithstanding
the foregoing, in the event that any or all of the outstanding principal
amounts of the Series 2005-2 Notes become or are declared to be due and payable
prior to the Legal Final Maturity Date, the Series Enhancer shall have no
obligation under the Policy to pay such amounts prior to the Legal Final
Maturity Date, unless the Series Enhancer shall elect to make such accelerated
payments in accordance with and subject to the terms of the Policy.  (l)The
Indenture Trustee shall be entitled to enforce on behalf of the Series 2005-2
Noteholders the obligations of the Series Enhancer under the Policy.  Notwithstanding any other provision of the
Indenture or any other Related  Document,
the Series 2005-2 Noteholders are not entitled to make any claims under the
Policy or institute proceedings directly against the Series Enhancer.  25
