information that is required to be included in the base prospectus and the prospectus supplement (collectively, the "Prospectus").
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 of your commitment to purchase, supersedes information contained in any prior
similar free writing prospectus relating to these securities. This free writing prospectus is not an offer to sell or a solicitation
of an offer to buy these securities in any state where such offer, solicitation or sale is not permitted. You should consult your
own counsel, accountant, and other advisors as to the legal, tax, business, financial and related aspects of a purchase of these
securities.
The attached information contains certain tables and other statistical analyses (the "Computational Materials") which have been
prepared by DBSI in reliance upon information furnished by the Depositor. Numerous assumptions were used in preparing the
Computational Materials that may or may not be reflected herein. As such, no assurance can be given as to whether the Computational
Materials and/or the assumptions upon which they are based reflect present market conditions or future market performance. These
Computational Materials should not be construed as either projections or predictions or as legal, tax, financial or accounting
advice. Any weighted average lives, yields and principal payment periods shown in the Computational Materials are based on
prepayment assumptions, and changes in such prepayment assumptions may dramatically affect such weighted average lives, yields and
principal payment periods. In addition, it is possible that prepayments on the underlying assets will occur at rates slower or
faster than the rates shown in the attached Computational Materials. Furthermore, unless otherwise provided, the Computational
Materials assume no losses on the underlying assets and no interest shortfalls. The specific characteristics of the securities may
differ from those shown in the Computational Materials by a permitted variance of +/-10% prior to issuance. Neither DBSI nor any of
its affiliates makes any representation or warranty as to the actual rate or timing of payments on any of the underlying assets or
the payments or yield on the securities.

the Distribution Date occurs or, if such day is not a business day, on the immediately preceding
business day.
Servicer Remittance Date: With respect to any Distribution Date, the 22nd day of the month in which such Distribution Date
occurs; provided that if the 22nd day of a given month is a Saturday, the Servicer Remittance Date

to the 15th day of the month of the Distribution Date, and (ii) with respect to principal
prepayments in part, the calendar month immediately preceding the month in which the Distribution

Interest Accrual Period: Interest will initially accrue on all Offered Certificates from the Closing Date to (but excluding)
the first Distribution Date, and thereafter, from the prior Distribution Date to (but excluding) the

flat (no accrued interest).
Interest Distribution Amount: For any class of Offered Certificates on any Distribution Date is equal to interest accrued during
the related Interest Accrual Period on the Certificate Principal Balance of that class immediately
prior to such Distribution Date at the then applicable pass-through rate for such class, and reduced
(to not less than zero), in the case of each such class, by the allocable share, if any, for such
class of prepayment interest shortfalls to the extent not covered by Compensating Interest paid by
the Master Servicer or the Servicer and shortfalls resulting from the application of the
Servicemembers' Civil Relief Act or similar state or local laws.

Optional Termination: On any Distribution Date on which the aggregate outstanding principal balance of the Mortgage Loans
(and properties acquired in respect of the Mortgage Loans) as of the related determination date is
less than or equal to 10% of the aggregate outstanding principal balance of the Mortgage Loans as of
the Cut-off Date, the Master Servicer may repurchase all of the Mortgage Loans and REO properties
remaining in the trust, causing an early retirement of the certificates, but is not required to do
so.
Monthly Servicer Advances: The Servicer will collect monthly payments of principal and interest on the Mortgage Loans and will
be obligated to make advances of delinquent monthly principal and interest payments. The Servicer is
required to advance delinquent payments of principal and interest on the Mortgage Loans only to the
extent such amounts are deemed recoverable. If the Servicer fails to make any such advance, the
Master Servicer will be required to do so subject to its determination of recoverability. The
Servicer and the Master Servicer are entitled to be reimbursed for such advances, and therefore
these advances are not a form of credit enhancement.
Credit Enhancement: 1) Excess Interest;
2) Overcollateralization ("OC"); and
3) Subordination.
Allocation of Losses: Any Realized Losses on the Mortgage Loans will be allocated on any Distribution Date, first, to Net
Monthly Excess Cashflow and Net Swap Payments received from the Swap Provider and available for this
purpose, if any, second, to the Class CE Certificates, third, to the Class M-9 Certificates, fourth,
to the Class M-8 Certificates, fifth, to the Class M-7 Certificates, sixth, to the Class M-6
Certificates, seventh, to the Class M-5 Certificates, eighth, to the Class M-4 Certificates, ninth,
to the Class M-3 Certificates, tenth, to the Class M-2 Certificates and eleventh, to the Class M-1
Certificates. There will be no allocation of Realized Losses to the Class A Certificates. Investors
in the Class A Certificates should note, however, that although Realized Losses cannot be allocated
to such certificates, under certain loss scenarios there may not be enough principal and interest on
the Mortgage Loans to distribute to the holders of the Class A Certificates all principal and
interest amounts to which they are then entitled.
Once Realized Losses have been allocated to the Mezzanine Certificates, such amounts with respect to
such Certificates will no longer accrue interest and such amounts will not be reinstated thereafter.
However, the amount of any Realized Losses allocated to the Mezzanine Certificates may be
distributed to such certificates on a subordinated basis on any Distribution Date from Net Monthly
Excess Cashflow, to the extent available for such distribution and any Net Swap Payments paid by the
Swap Provider and available for this purpose.
Required Overcollateralization refers to the amount by which the aggregate principal balance of the
Overcollateralization Amount: Mortgage Loans exceeds the aggregate Certificate Principal Balance of the certificates. This excess
(the "Overcollateralization Amount") is intended to protect the certificateholders against
shortfalls in payments on the certificates. The Required Overcollateralization Amount for the
certificates, which will be established at issuance and which is equal to the Overcollateralization
Amount as of the Closing Date, is anticipated to be approximately 4.00% of the aggregate principal
balance of the Mortgage Loans as of the Cut-off Date. On or after the Stepdown Date and provided
that a trigger event is not in effect, the Required Overcollateralization Amount may be permitted to
decrease to approximately 8.00% of the aggregate principal balance of the Mortgage Loans as of the
end of such Due Period, subject to a floor amount of approximately 0.50% of the aggregate principal
balance of the Mortgage Loans as of the Cut-off Date. If, due to losses, the Overcollateralization
Amount is reduced below the Required Overcollateralization Amount, excess spread, to the extent
available will be paid to the certificates then entitled to receive distributions in respect of
principal in order to reduce the Certificate Principal Balance of such certificates to the extent
necessary to reach the Required Overcollateralization Amount. In addition, Net Swap Payments paid by
the Swap Provider may be used to restore or maintain the Required Overcollateralization Amount.

Net WAC Pass-Through Rate: Class A-1 Certificates and Class A-2 Certificates: The per annum rate (subject to adjustment based
on the actual number of days elapsed in the related Interest Accrual Period) equal to the product of
(i) 12 and (ii) a fraction, expressed as a percentage, the numerator of which is the amount of
interest which accrued on the Mortgage Loans in the related loan group during the related Due Period
minus the fees payable to the Servicer, the Master Servicer and the Credit Risk Manager and with
respect to the related Mortgage Loans for such Distribution Date, the Group I Allocation Percentage
or Group II Allocation Percentage, as applicable, of any Net Swap Payment or Swap Termination
Payment made to the Swap Provider which was not caused by the occurrence of a Swap Provider trigger
event, in each case for such Distribution Date, and the denominator of which is the aggregate
principal balance of the Mortgage Loans in the related loan group as of the last day of the
immediately preceding Due Period (or as of the Cut-off Date with respect to the first Distribution
Date), after giving effect to principal prepayments received during the related Prepayment Period
which were distributed on the immediately preceding Distribution Date.
Mezzanine 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 aggregate
Certificate Principal Balance of the related Class A Certificates), of (i) the Net WAC Pass-Through
Rate for the Class A-1 Certificates and (ii) the Net WAC Pass-Through Rate for the Class A-2
Certificates.
Group I Allocation Percentage: The aggregate principal balance of the Group I Mortgage Loans divided
by the sum of the aggregate principal balance of the Group I Mortgage Loans and the Group II
Mortgage Loans.
Group II Allocation Percentage: The aggregate principal balance of the Group II Mortgage Loans
divided by the sum of the aggregate principal balance of the Group I Mortgage Loans and the Group II
Mortgage Loans.
Net WAC Rate Carryover Amount: On any Distribution Date the "Net WAC Rate Carryover Amount" for any class of certificates will be
equal to the sum of (i) the excess of (a) the amount of interest that would have accrued on such
class based on One-Month LIBOR plus the related margin over (b) the amount of interest accrued on
such class based on the related Net WAC Pass-Through Rate and (ii) the unpaid portion of any related
Net WAC Rate Carryover Amount from the prior Distribution Date together with interest accrued on
such unpaid portion at a rate equal to One-Month LIBOR plus the related margin for the most recently
ended Interest Accrual Period. Any Net WAC Rate Carryover Amount will be paid on such Distribution
Date or future Distribution Dates to the extent of funds available. The Net WAC Rate Carryover
Amount with respect to a class of certificates will be distributed from cap payments, if any, paid
by the cap provider pursuant to the related Cap Agreement (described below), Net Monthly Excess
Cashflow on a subordinated basis on the same Distribution Date or on any subsequent Distribution
Date to the extent of available funds, and from certain amounts received by the Securities
Administrator, on behalf of the supplemental interest trust (described below), under the Swap
Agreement, if any. The ratings on each class of Certificates do not address the likelihood of the
payment of any Net WAC Rate Carryover Amount from Net Monthly Excess Cashflow.
Interest Carry Forward Amount: For any Distribution Date, will be equal to the amount, if any, by which the Interest Distribution
Amount for that class of certificates for the immediately preceding Distribution Date exceeded the
actual amount distributed on such class in respect of interest on the immediately preceding
Distribution Date, together with any Interest Carry Forward Amount with respect to such class
remaining unpaid from the previous Distribution Date, plus interest accrued thereon at the related
pass-through rate for the most recently ended Interest Accrual Period.

Swap Agreement: On the Closing Date, the Trustee will enter into a Swap Agreement with the Swap Provider identified
in the final prospectus supplement. Beginning with the Distribution Date in October 2007 the Swap
Agreement will have an initial notional amount of $666,415,204. Beginning with the Distribution Date
in October 2007, the Trust (through a supplemental interest trust) will be obligated to pay to the
Swap Provider an amount equal to the product of (i) [4.90]% per annum, (ii) the Swap Notional Amount
(as defined below) and (iii) a fraction, the numerator of which is 30 and the denominator of which
is 360, and the Swap Provider will be obligated to pay to the supplemental interest trust, for the
benefit of the holders of the Class A Certificates and the Mezzanine Certificates, an amount equal
to the product of (i) One-Month LIBOR, (ii) the Swap Notional Amount and (iii) a fraction, the
numerator of which is the actual number of days elapsed during the related Interest Accrual Period
and the denominator of which is 360, until the Swap Agreement is terminated. The "Swap Notional
Amount" for each Distribution Date will be equal to the lesser of (a) the scheduled swap notional
amount set forth in the Swap Agreement for such Distribution Date and (b) the Certificate Principal
Balance of the Offered Certificates. Only the net amount of the two obligations will be paid by the
appropriate party (the "Net Swap Payment"). See the attached schedule.
A separate trust created under the pooling and servicing agreement (the "Supplemental Interest
Trust") will hold the Swap Agreement. The Swap Agreement and any payments made by the Swap Provider
thereunder will be assets of the Supplemental Interest Trust but will not be assets of any REMIC.
Upon early termination of the Swap Agreement, the Supplemental Interest Trust or the Swap Provider
may be liable to make a termination payment (the "Swap Termination Payment") to the other party
(regardless of which party caused the termination). The Swap Termination Payment will be computed in
accordance with the procedures set forth in the Swap Agreement. In the event that the Securities
Administrator, on behalf of the Supplemental Interest Trust, is required to make a Swap Termination
Payment, that payment will be paid on the related Distribution Date, and on any subsequent
Distribution Dates until paid in full, and, if such Swap Termination Payment is not due as a result
of the occurrence of a Swap Provider Trigger Event (as defined in the Swap Agreement), such payment
will be prior to distributions to Certificateholders.
Group I Cap Agreement: On the Closing Date, the Trustee will enter into a "Group I Cap Agreement", which will be effective
for the period commencing on the Distribution Date occurring in April 2007 and ending on the
Distribution Date immediately following the Distribution Date occurring in September 2007, to make
payments in respect of any Net WAC Rate Carryover Amounts in respect of the Class A-1 Certificates
and the Mezzanine Certificates as described herein. The Group I Cap Agreement requires a cap payment
in an amount equal to the product of: (1) the excess, if any, of One-Month LIBOR over a specified
strike rate for the related Distribution Date; (2) the related scheduled notional amount, which is
based on the lesser of (i) the expected amortization of the Group I Mortgage Loans and (ii) the
Group I Cap Schedule, and (3) a fraction, the numerator of which is the actual number of days
elapsed during the related Interest Accrual Period and the denominator of which is 360.

Class A Principal Until the Stepdown Date, the Class A Principal Distribution Amount will be distributed to the
Distribution Amount: holders of the Class A-1 Certificates and the Class A-2 Certificates concurrently, on a pro rata
basis based on the related Class A principal allocation percentage (for any Distribution Date, the

the Group I Mortgage Loans (in the case of the Class A-1 Certificates) or the principal remittance
amount for the Group II Mortgage Loans (in the case of the Class A-2 Certificates) and the
denominator of which is equal to the principal remittance amount for all of the Mortgage Loans).
Until the Stepdown Date, or if a Trigger Event is in effect, the Class A Certificates will receive

restore the Required Overcollateralization Amount until the aggregate Certificate Principal Balance
of the Class A Certificates has been reduced to zero. On or after the Stepdown Date, if no Trigger
Event occurs, principal paid on the Class A Certificates will be an amount such that the Class A
Certificates will maintain approximately a 40.20% Credit Enhancement Percentage (2x the Class A
Initial Credit Enhancement Percentage). The Class A Principal Distribution Amount will be
distributed to the holders of the Class A-1 and Class A-2 Certificates to the extent of their
respective group-based principal distribution amount.
Principal distributions to the Class A-2 Certificates will be allocated sequentially to the Class
A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, in that order, until the Certificate
Principal Balance of each such class has been reduced to zero; provided, however, on any
Distribution Date on which the aggregate Certificate Principal Balance of the Mezzanine Certificates
has been reduced to zero, all principal distributions will be distributed to the Class A-2
Certificates on a pro rata basis, based on the Certificate Principal Balance of each such class,
until the Certificate Principal Balance of each such class has been reduced to zero.

Distribution Amount: any principal payments until the Stepdown Date. On or after the Stepdown Date (if no Trigger Event
is in effect), principal will be paid to the Mezzanine Certificates, first to the Class M-1
Certificates until it reaches approximately 33.40% Credit Enhancement Percentage (2x the Class M-1
Initial Credit Enhancement Percentage), second to the Class M-2 Certificates until it reaches
approximately 27.50% Credit Enhancement Percentage (2x the Class M-2 Initial Credit Enhancement
Percentage), third to the Class M-3 Certificates until it reaches approximately a 24.10% Credit
Enhancement Percentage (2x the Class M-3 Initial Credit Enhancement Percentage), fourth to the Class
M-4 Certificates until it reaches approximately a 21.00% Credit Enhancement Percentage (2x the Class
M-4 Initial Credit Enhancement Percentage), fifth to the Class M-5 Certificates until it reaches
approximately a 18.00% Credit Enhancement Percentage (2x the Class M-5 Initial Credit Enhancement
Percentage), sixth to the Class M-6 Certificates until it reaches approximately a 15.10% Credit
Enhancement Percentage (2x the Class M-6 Initial Credit Enhancement Percentage), seventh to the
Class M-7 Certificates until it reaches approximately a 12.20% Credit Enhancement Percentage (2x the
Class M-7 Initial Credit Enhancement Percentage), eighth to the Class M-8 Certificates until it
reaches approximately a 10.00% Credit Enhancement Percentage (2x the Class M-8 Initial Credit
