This free writing prospectus is not
required to contain all information that is
required to be included in the base
prospectus and the prospectus supplement.
The information in this free writing
prospectus is preliminary and is subject to
completion or change.
The information in this free writing
prospectus, if conveyed prior to the time

accounting advice.
Any yields or weighted average lives shown
in the Free Writing Prospectus are
based on prepayment assumptions and actual
prepayment experience may
dramatically affect such yields or weighted
average lives. In addition, it is
possible that prepayments on the underlying
assets will occur at rates slower or
faster than the rates assumed in the Free
Writing Prospectus. Furthermore,
unless otherwise provided, the Free Writing
Prospectus assumes no losses on the
underlying assets and no interest
shortfall. The specific characteristics of the

auction will be effected
via a solicitation of bids from at least three bidders. Any such
auction will result in the
termination of the Trust Fund only if the highest bid received is
at least equal to the sum of (i)
the aggregate outstanding principal balance of the Certificates,
plus accrued interest on the
Certificates, (ii) any unreimbursed out-of-pocket costs and

OVER-COLLATERALIZATION
The over-collateralization ("O/C") amount is equal to the excess of
the aggregate principal balance
of the Mortgage Loans over the aggregate principal balance of the
Certificates. On the Closing Date,
the over-collateralization amount will equal approximately 4.60% of
the aggregate principal
balance of the Mortgage Loans as of the Cut-Off Date. To the extent
the over-collateralization
amount is reduced below the over-collateralization target amount
(i.e., 4.60% of the aggregate
principal balance of the Mortgage Loans as of the Closing Date),
excess cashflow will be directed to
build O/C until the over-collateralization target amount is
restored.
Initial: Approximately 4.60% of the aggregate principal balance of
the Mortgage Loans as of the
Cut-Off Date
Target: 4.60% of the aggregate principal balance of the Mortgage
Loans as of the
Cut-Off Date before stepdown, 9.20% of the current balance of the
Mortgage Loans after stepdown
Floor: 0.50% of the original balance of the
aggregate principal balance of the Mortgage Loans as of the Cut-Off
Date

AVAILABLE FUNDS CAPS
Class A-1 Certificates: The per annum rate equal to (A) 12 times
the quotient of (x) the total
scheduled interest based on the Group I Net Mortgage Rates in
effect on the related due date,
divided by (y) the aggregate principal balance of the Group I
Mortgage Loans as of the first day of
the applicable accrual period, multiplied by 30 and divided by the
actual number of days in the
related accrual period.
Class A-2 Certificates: The per annum rate equal to (A) 12 times
the quotient of (x) the total
scheduled interest based on the Group II Net Mortgage Rates in
effect on the related due date,
divided by (y) the aggregate principal balance of the Group II
Mortgage Loans as of the first day of
the applicable accrual period, multiplied by 30 and divided by the
actual number of days in the
related accrual period.
Subordinate Certificates: The per annum rate equal to the weighted
average (weighted in proportion to
the results of subtracting from the aggregate principal balance of
each loan group the current
principal balance of the related Class A Certificates) of the Class
A-1 Available Funds Cap
and the Class A-2 Available Funds Cap.
"Net Mortgage Rate" means, with respect to any mortgage loan the
mortgage rate on such mortgage
loan less the administrative fees.
CAP CONTRACTS
The Certificates will each have the benefit of one of the three cap
contracts as specified below:

Payments received on the related cap contract will be available to
pay amounts to the holders of the
Certificates, in respect of shortfalls arising as a result of the
applicable Available Funds Cap, as
described herein (except to the extent attributable to the fact
that Realized Losses are
not allocated to the Class A Certificates after the Subordinate
Certificates have been written
down to zero).
MAXIMUM RATE CAPS
The pass-through rates of each of the Offered Certificates will
also be subject to a related
"Maximum Rate Cap", which will be calculated in the same manner as
the related Available Funds Cap,
but based on the net maximum mortgage rate rather than the net
mortgage rate. Any interest shortfall
due to the Maximum Rate Caps will not be reimbursed.
SHORTFALL REIMBURSEMENT If
on any Distribution Date the pass-through rate for any class of
Certificates is limited by the
related Available Funds Cap, the amount of such interest that would
have been distributed if the
pass-through rate had not been so limited by the related Available
Funds Cap, up to but not exceeding
the greater of (i) the related Maximum Rate Cap and (ii) the lesser
of (A) One Month LIBOR and (B) the
applicable rate for the related class or classes of certificates
shown under the heading, "1ML Strike,
Upper Collar", under the heading, "Cap Contracts" shown above), and
the aggregate of such shortfalls
from previous Distribution Dates together with accrued interest at
the pass-through rate will be
carried over to the next Distribution Date until paid (herein
referred to as "Carryover"). Such
reimbursement will be paid only on a subordinated basis. No such
Carryover with respect to a Class
will be paid to such Class once the Certificate principal balance
thereof has been reduced to zero.

DISTRIBUTION TEST IS NOT MET:
1) The Group I Principal
Distribution Percentage of (i) scheduled and
unscheduled principal received from the Mortgage Loans and (ii)
excess
spread to the extent distributable as principal to replenish O/C
to
the required level will be paid to the Class A-1 Certificates.
2) The Group II Principal
Distribution Percentage of (i) scheduled and
unscheduled principal received from the Mortgage Loans and (ii)
excess
spread to the extent distributable as principal to replenish O/C
to
the required level will be paid to the Class A-2 Certificates.
Group I Principal
Distribution Percentage means with respect to any
Distribution
Date, the fraction expressed as a percentage, the numerator of
which is the
amount of scheduled and unscheduled principal received with
respect to Group
I mortgage loans and distributable on such Distribution
Date, and the
denominator of which is the amount of scheduled and
unscheduled
principal received from all of the Mortgage Loans and
distributable on
such Distribution Date.
Group II
Principal Distribution Percentage means with respect to any
Distribution
Date, the fraction expressed as a percentage, the numerator of
which is the
amount of scheduled and unscheduled principal received with
respect to Group
II mortgage loans and distributable on such Distribution
Date, and the
denominator of which is the amount of scheduled and
unscheduled
principal received from all of the Mortgage Loans and
distributable on
such Distribution Date.
Principal
distributions allocated to the Class A-2 Certificates will be
distributed to
the Class A-2A Certificates until the Certificate principal
balance thereof
has been reduced to zero, then to the Class A-2B
Certificates
until the Certificate principal balance thereof has been
reduced to zero
and then to the Class A-2C Certificates until the
Certificate
principal balance thereof has been reduced to zero; provided,
however, that on
and after the Distribution Date on which the aggregate
Certificate
Principal Balance of the Subordinate Certificates have been
reduced to zero,
any principal distributions allocated to the Class A-2A,
Class A-2B and
Class A-2C Certificates are required to be allocated pro
rata among such
classes of Certificates based on their respective
Certificate
Principal Balances, until their Certificate Principal Balances
have been
reduced to zero.
After the
Certificate principal balance of either the Class A-1 or Class
A-2 Certificates
has been reduced to zero, the amounts remaining referred
to in (1) or (2)
above, as applicable, will be distributed to the Class A-1
or Class A-2
Certificates (i.e., whichever such class or classes remain
outstanding), as
the case may be. After the aggregate Certificate principal
balance of both
the Class A-1 and Class A-2 Certificates has been reduced
to zero, the
amounts remaining referred to in (1) and (2) above will be
distributed
sequentially to the Class M-1, Class M-2, Class M-3, Class M-4,
Class M-5, Class
M-6, Class B-1, Class B-2 and Class B-3 Certificates.
