The analysis in this report is based on information provided by ACE Securities Corp. (the "Depositor"). Investors are urged to read
the base prospectus and the prospectus supplement and other relevant documents filed or to be filed with the Securities and Exchange
Commission because they contain important information. Such documents may be obtained without charge at the Securities and Exchange
Commission's website. Once available, the base prospectus and prospectus supplement may be obtained without charge by contacting
Deutsche Bank Securities, Inc.'s ("DBSI") trading desk at (212) 250-7730. 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 (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.

An investor or potential investor in the certificates (and each employee, representative, or other agent of such person or entity)
may disclose to any and all persons, without limitation, the tax treatment and tax structure of the transaction (as defined in
United States Treasury Regulation Section 1.6011-4) and all related materials of any kind, including opinions or other tax analyses,
that are provided to such person or entity. However, such person or entity may not disclose any other information relating to this
transaction unless such information is related to such tax treatment and tax structure.

THIS INFORMATION IS FURNISHED TO YOU SOLELY BY DBSI AND NOT BY THE ISSUING ENTITY OF THE SECURITIES OR ANY OF ITS AFFILIATES. DBSI

                                     and (ii) with respect to prepayments in part, the prior calendar month.

Interest Accrual Period:             Interest will initially accrue on the Offered Certificates from the Closing
                                     Date to (but excluding) the first Distribution Date, and thereafter, from the prior
                                     Distribution Date to (but excluding) the current Distribution Date on an actual/360 basis. The
                                     Offered Certificates will initially settle flat (no accrued interest).

Interest Distribution                For the Offered Certificates on any Distribution Date is equal to interest accrued during the
Amount:                              related Interest Accrual Period on the Certificate Principal Balance thereof immediately prior
                                     to such Distribution Date at the then applicable pass-through rate for the Offered
                                     Certificates, and reduced (to an amount not less than zero), in the case of each such class, by
                                     the allocable share, if any, for the Offered Certificates of prepayment interest shortfalls to
                                     the extent not covered by Compensating Interest paid by the Master Servicer or the Servicers
                                     and shortfalls resulting from the application of the Servicemembers' Civil Relief Act or
                                     similar state or local laws.

Senior Interest                      For the Offered Certificates on any Distribution Date is an amount equal to the sum of the
Distribution Amount:                 Interest Distribution Amount for such Distribution Date and the Interest Carry Forward Amount,
                                     if any, for such Distribution Date.

Administration Fee Rate:             The Master Servicer, the Servicers and the Credit Risk Manager will be paid monthly fees on the
                                     outstanding principal balance of the Mortgage Loans. These fees ("Administration Fee Rate")
                                     initially aggregate to a weighted average servicing fee of approximately 0.5835% per annum with
                                     respect to the Mortgage Loans.

Compensating Interest:               Each Servicer will be required to cover Prepayment Interest Shortfalls on prepayments in full
                                     on the Mortgage Loans serviced by such Servicer received during the portion of the related
                                     Prepayment Period occurring between the 16th day of the month prior to the month of the
                                     Distribution Date to the last day of such prior month up to the Servicing Fee payable to the
                                     related Servicer. If a Servicer fails to make such payments, the Master Servicer will be
                                     required to do so in an amount not to exceed the compensation payable to the Master Servicer.

Prepayment Interest                  Interest shortfalls attributable to voluntary principal prepayments on the Mortgage
Shortfalls:                          Loans.

Expense Adjusted                     For any Mortgage Loan for any Distribution Date shall be a per annum rate equal to the
Mortgage Rate:                       applicable Mortgage Rate for such Mortgage Loan as of the first day of the month preceding the
                                     month in which such Distribution Date occurs minus the Administration Fee Rate.

Optional Termination:                On any Distribution Date on which the aggregate outstanding principal balance 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 purchase 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. In the event that the
                                     Master Servicer fails to exercise such purchase option on the first possible optional
                                     termination date, each Servicer may, subject to certain conditions set forth in the pooling and
                                     servicing agreement, exercise such purchase option. In the event either the Master Servicer or
                                     a Servicer exercises this option, the portion of the purchase price allocable to the Offered
                                     Certificates will be, to the extent of available funds, (i) 100% of the then outstanding
                                     Certificate Principal Balance of the Offered Certificates, plus (ii) one month's interest on
                                     the then outstanding Certificate Principal Balance thereof at the then applicable pass-through
                                     rate, plus (iii) any previously accrued but unpaid interest thereon to which the holders of the
                                     Offered Certificates are entitled, together with the amount of any Net WAC Rate Carryover
                                     Amounts.

Monthly Servicer Advances:           The Servicers will collect monthly payments of principal and interest on the related Mortgage
                                     Loans and will be obligated to make advances of delinquent monthly principal and interest
                                     payments but only to the extent such amounts are deemed recoverable. If a Servicer fails to
                                     make any such advances, the Master Servicer will be required to do so subject to its
                                     determination of recoverability. The Servicers and the Master Servicer are entitled to be
                                     reimbursed for these advances, and therefore these advances are not a form of credit
                                     enhancement.

Credit Enhancement:                  1) Excess Interest;
                                     2) Overcollateralization ("OC"); and
                                     3) The Class A-1 Certificate Insurance Policy.

- ------------------------------------------------------------------------------------------------------------------------------------

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 made by the Swap Provider, if any, second, to the
                                 Class CE-1 Certificate and third, to the Class A-1 Certificates.

                                 Once Realized Losses have been allocated to the Class A-1 Certificates, such amounts with respect
                                 to the Class A-1 Certificates will no longer accrue interest and such amounts will not be
                                 reinstated thereafter (except in the case of subsequent recoveries). However, the amount of any
                                 Realized Losses allocated to the Class A-1 Certificates may be distributed to the Class A-1
                                 Certificates on a subordinated basis on any Distribution Date from Net Monthly Excess Cashflow, to
                                 the extent available for such distribution or from any Net Swap Payments payable by the Swap
                                 Provider available for this purpose. Realized Losses on the Mortgage Loans will be allocated to the
                                 Class A-1 Certificates, provided, however, that any such losses allocated to the Class A-1
                                 Certificates will be covered by the Policy.

                                 A "Realized Loss" for a Liquidated Mortgage Loan is equal to the principal balance of such
                                 Liquidated Mortgage Loan plus interest thereon from the date on which interest was last paid less
                                 any liquidation proceeds received on such Mortgage Loan and for a Charged Off Mortgage Loan is
                                 equal to the principal balance of such Charged Off Mortgage Loan plus interest thereon from the
                                 date on which interest was last paid.

                                 A "Liquidated Mortgage Loan" is a Mortgage Loan that was liquidated and for which the related
                                 Servicer has determined that it has received all amounts it expects to receive in connection with
                                 such liquidation, including payments under any related private mortgage insurance policy, hazard
                                 insurance policy or any condemnation proceeds and amounts received in connection with the final
                                 disposition of the related REO property.

                                 A "Charged Off Mortgage Loan" is a defaulted Mortgage Loan that the related Servicer is required to
                                 charge off once such Mortgage Loan becomes 180 days delinquent provided that such Mortgage Loan has
                                 not yet been liquidated and provided further, that the related Servicer has determined, based on a
                                 broker's price opinion and other relevant considerations, that no significant net recovery is
                                 possible through foreclosure proceedings or other liquidation of the related mortgaged property or
                                 that the potential net recovery is anticipated to be an amount that is insufficient to warrant
                                 proceeding through foreclosure or other liquidation of the related mortgaged property.

Required                         Overcollateralization refers to the amount by which the aggregate principal balance of the Mortgage
Overcollateralization            Loans exceeds the aggregate Certificate Principal Balance of the Offered Certificates and the Class
Amount:                          P Certificates. This excess (the "Overcollateralization Amount") is intended to protect the Offered
                                 Certificates against shortfalls in payments on the Certificates. The Required Overcollateralization
                                 Amount for the Offered Certificates, which will be fully established at issuance, is initially
                                 anticipated to be an amount equal to the product of (i) approximately 31.45% and (ii) 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 62.90% of the aggregate principal balance of the Mortgage
                                 Loans as of the last day of the related Due Period, subject to a floor amount of approximately
                                 0.50% of the aggregate outstanding 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 Class A-1
                                 Certificates in respect of principal in order to reduce the Certificate Principal Balance of the
                                 Class A-1 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.

Overcollateralization            An Overcollateralization Increase Amount for any Distribution Date is the lesser of (i) the Net
Increase Amount:                 Monthly Excess Cashflow and Net Swap Payments received from the Swap Provider, if any, for that
                                 Distribution Date and (ii) the excess of the Required Overcollateralization Amount over the current
                                 Overcollateralization Amount.

Overcollateralization            An Overcollateralization Reduction Amount for any Distribution Date is the amount by which the
Reduction Amount:                current Overcollateralization Amount exceeds the Required Overcollateralization Amount after taking
                                 into account all other distributions to be made on the Distribution Date limited to the
                                 distribution of principal on the Mortgage Loans.

Stepdown Date:                   Is the earlier of (i) the first Distribution Date following the Distribution Date on which the
                                 Certificate Principal Balance of the Class A-1 Certificates is reduced to zero and (ii) the later
                                 to occur of (x) the Distribution Date occurring in August 2010 and (y) the first Distribution Date
                                 on which the Class A-1 Credit Enhancement Percentage (calculated for this purpose only after taking
                                 into account distributions of principal on the Mortgage Loans, but prior to any distribution of
                                 principal to the holders of the Class A-1 Certificates) is equal to or greater than approximately
                                 62.90%.

Class A-1 Credit                 The Credit Enhancement Percentage for the Class A-1 Certificates and any Distribution Date is the
Enhancement                      percentage obtained by dividing (x) the Overcollateralization Amount by (y) the aggregate principal
Percentage:                      balance of the Mortgage Loans, calculated after giving effect to scheduled payments of principal
                                 due during the related Due Period, to the extent received or advanced, and unscheduled collections
                                 of principal received during the related Prepayment Period and distribution of the Principal
                                 Distribution Amount to the holders of the Class A-1 Certificates on the Distribution Date.

                                 Class              (S/M)                  Initial CE %          CE % On/After Step Down Date

                                 A-1                AAA / Aaa                 31.45%                       62.90%

Net Monthly Excess               For any Distribution Date is equal to the sum of (i) any Overcollateralization Reduction Amount and
Cashflow:                        (ii) the excess of the Available Distribution Amount over the sum of (w) the Senior Interest
                                 Distribution Amount for such Distribution Date, (x) the amount of principal required to be
                                 distributed to the holders of the Class A-1 Certificates on such Distribution Date, (y) any Net
                                 Swap Payment or Swap Termination Payment (not caused by a Swap Provider Trigger Event (as defined
                                 in the Swap Agreement)), owed to the Swap Provider and (z) any amount required to be paid to the
                                 Certificate Insurer on such Distribution Date.

Net WAC Pass-                    The per annum rate (subject to adjustment based on the actual number of days elapsed in the related
Through Rate:                    Interest Accrual Period) equal to the product of (i) 12 and (ii) a fraction, expressed as a
                                 percentage, the numerator of which is the difference of (a) the amount of interest which accrued on
                                 the Mortgage Loans in the prior calendar month minus the fees payable to the Servicers, the Master
                                 Servicer and the Credit Risk Manager with respect to the related Mortgage Loans for such
                                 Distribution Date and the premium payable to the Certificate Insurer, over (b) any Net Swap Payment
                                 or Swap Termination Payment made to the Swap Provider for such Distribution Date (which was not
                                 caused by a Swap Provider Trigger Event as defined in the Swap Agreement), and the denominator of
                                 which is the aggregate principal balance of the Mortgage Loans 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.

Net WAC Rate                     If on any Distribution Date the Pass-Through Rate for the Class A-1 Certificates is limited by the
Carryover Amount:                Net WAC Pass-Through Rate, the Class A-1 Certificates will be entitled to the "Net WAC Rate
                                 Carryover Amount" which will be equal to the sum of (i) the excess, if any 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 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 will be distributed from certain amounts received by
                                 the Securities Administrator, on behalf of the supplemental interest trust (described below), under
                                 the Swap Agreement, if any, the Cap Agreement, if any, and from the Net Monthly Excess Cashflow on
                                 the same Distribution Date or on any subsequent Distribution Date to the extent of available funds.
                                 The ratings on the Offered Certificates do not address the likelihood of the payment of any Net WAC
                                 Rate Carryover Amount from Net Monthly Excess Cashflow.

Cap Agreement:                   On the Closing Date, the Trustee will enter into a "Cap Agreement", which will be effective for the
                                 period commencing on the Distribution Date occurring in August 2007 and ending immediately
                                 following the Distribution Date occurring in January 2008, to make payments in respect of any Net
                                 WAC Rate Carryover Amounts in respect of the Class A-1 Certificates as described herein. The 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 cap
                                 notional amount, which is based on the lesser of (i) the expected amortization of the Mortgage
                                 Loans and (ii) Scheduled Cap Notional Amount for the related Distribution Date and (3) a fraction,
                                 the numerator of which is the actual number of days elapsed from the previous Distribution Date to
                                 but excluding the current Distribution Date (or, for the first Distribution Date, the actual number
                                 of days elapsed from the Closing Date to but excluding the first Distribution Date), and the
                                 denominator of which is 360. The Scheduled Cap Notional Amount for each Distribution Date during
                                 the term of the Cap Agreement is set forth on page 14 of this free writing prospectus.

Swap Agreement:                  On the Closing Date, the Trustee in its capacity as supplemental interest trust trustee will enter
                                 into a Swap Agreement with the Swap Provider described in the prospectus supplement. The Swap
                                 Agreement will have an initial notional amount of $[111,384,708]. Beginning with the Distribution
                                 Date in February 2008, the trust (through a supplemental interest trust) will be obligated to pay
                                 an amount equal to the product of (i) [5.33]% 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 Offered 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 aggregate Certificate Principal Balance of the Offered Certificates
                                 on the day immediately preceding such Distribution Date, and (b) the scheduled swap notional amount
                                 set forth in the Swap Agreement for such Distribution Date. 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 Securities Administrator on behalf of 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 which is not payable as a result of
                                 the occurrence of a swap provider trigger event under the Swap Agreement, that payment will be paid
                                 on the related Distribution Date, and on any subsequent Distribution Dates until paid in full prior
                                 to distributions to Certificateholders.

The Class A-1                    It is anticipated that the Class A-1 Certificates will have the benefit of a certificate guaranty
Certificate                      insurance policy (the "Policy") pursuant to which the Certificate Insurer, in consideration of the
Insurance Policy:                payment of a premium and subject to the terms of the Policy, unconditionally and irrevocably will
                                 guarantee the timely payment of interest (other than certain interest shortfalls specified in the
                                 Policy) and the ultimate payment of principal on the Class A-1 Certificates on the final
                                 Distribution Date. In addition, the Certificate Insurer will guarantee the payment of the principal
                                 portion of any Realized Losses allocated to the Class A-1 Certificates. The Policy will not be
                                 cancelable for any reason. The Policy will not cover any interest shortfalls resulting from
                                 prepayments or applications of the Servicemembers Civil Relief Act or similar state or local laws.
                                 Subject to the terms of the pooling and servicing agreement, the Certificate Insurer will be
                                 subrogated to the rights of the Class A-1 Certificateholders to receive payments under the Class
                                 A-1 Certificates to the extent of any payment by the Certificate Insurer under the Policy.

Class A Principal
Distribution Amount:             Until the Stepdown Date, or if a Trigger Event occurs, the Class A-1 Certificates will receive the
                                 principal collected on the Mortgage Loans plus any excess interest and any Net Swap Payment
                                 received by the Securities Administrator from the Swap Provider required to restore or maintain the
                                 Required Overcollateralization Amount until the aggregate Certificate Principal Balance of the
                                 Class A-1 Certificates has been reduced to zero. On or after the Stepdown Date, if no Trigger Event
                                 occurs, principal paid on the Class A-1 Certificates will be an amount such that the Class A-1
                                 Certificates will maintain approximately a 62.90% Credit Enhancement Percentage (2x the Class A-1
                                 Credit Enhancement Percentage).

Coupon Step-up:                  On the Distribution Date following the first possible optional termination date, the margin on the
                                 Class A-1 Certificates will increase to the following, subject to the Net WAC Pass-Through Rate.

Trigger Event:                   If either the Delinquency Test or Cumulative Loss Test is violated.

Delinquency Test:                The determination on any Distribution Date that the percentage obtained by dividing (x) the
                                 principal amount of (1) Mortgage Loans delinquent 60 days or more, (2) Mortgage Loans in
                                 foreclosure, (3) REO Properties and (4) Mortgage Loans discharged due to bankruptcy by (y) the
                                 aggregate principal balance of the Mortgage Loans, in each case, as of the last day of the previous
                                 calendar month, exceeds 12.90%.

Cumulative Loss Test:            The determination on any Distribution Date that the aggregate amount of Realized Losses incurred
                                 since the Cut-off Date through the last day of the related Due Period divided by the aggregate
                                 principal balance of the Mortgage Loans as of the Cut-off Date exceeds the applicable percentages

                              other than Swap Termination Payments resulting from a Swap Provider Trigger Event (and to the extent
                              not paid by the Securities Administrator from any upfront payment received pursuant to any replacement
                              interest rate swap agreement that may be entered into by the Supplemental Interest Trust Trustee) will

                                   (i)   first, to make any Net Swap Payment owed to the Swap Provider pursuant to the Swap
                                         Agreement for such Distribution Date, and

                                   (ii)  second, to make any Swap Termination Payment not due to a Swap Provider Trigger Event owed
                                         to the Swap Provider pursuant to the Swap Agreement (to the extent not paid by the
                                         Securities Administrator from any upfront payment received pursuant to any replacement
                                         interest rate swap agreement that may be entered into by the Securities Administrator).

                              purchase the Offered Certificates if the purchase and holding meets the requirements of an
                              investor-based class exemption issued by the Department of Labor. Investors should consult with their
                              counsel with respect to the consequences under ERISA and the Internal Revenue Code of a Plan's
                              acquisition and ownership of such Offered Certificates.
