The analysis in this report is based on information  provided by ACE Securities Corp. (the "Depositor") and is ABS informational and
computational  material used in reliance on Securities Act Rule 167 (230.167).  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.
The Commission file number for the related registration statement is 333-131727.  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 term sheet 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 term sheet is preliminary  and is subject to completion or
change.  The information in this term sheet, if conveyed prior to the time of your  commitment to purchase,  supersedes  information
contained in any prior similar term sheet relating to these securities. This term sheet 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.

                                                  Transaction Overview (Cont.)
---------------------------------------------------------------------------------------------------------------------------------
Determination Date:             With  respect  to any  Distribution  Date,  the 15th  day of the  calendar  month in which  such
                                Distribution  Date  occurs  or,  if such  15th  day is not a  business  day,  the  business  day
                                immediately preceding such 15th day.

Due Period:                     The Due Period  with  respect to any  Distribution  Date will  commence on the second day of the
                                month  immediately  preceding  the month in which such  Distribution  Date occurs and end on the
                                first day of the month in which such Distribution Date occurs.

Prepayment Period:              With respect to each  Distribution  Date, the calendar  month  preceding the month in which such
                                Distribution Date occurs.

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 Amount:   For the Offered  Certificates  of any class on any  Distribution  Date will be 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 an amount not less than zero),  in the case of each such class,  by
                                the allocable share, if any, for such class of (i) prepayment  interest shortfalls to the extent
                                not  covered by  Compensating  Interest  paid by the  Servicer or the Master  Servicer  and (ii)
                                shortfalls  resulting from the application of the Servicemembers'  Civil Relief Act (the "Relief
                                Act") or similar state or local laws.

Interest Carry Forward Amount:  For any class of interest bearing  certificates  and any  Distribution  Date, the sum of (i) the
                                excess,  if any, of the Interest  Distribution  Amount for the prior  Distribution  Date and any
                                Interest Carry Forward  Amount for the prior  Distribution  Date,  over the amount in respect of
                                interest  actually  distributed on such class on such prior  Distribution Date and (ii) interest
                                on such excess at the  applicable  pass-through  rate on the basis of the actual  number of days
                                elapsed since the prior Distribution Date.

Senior Interest Distribution    On  any  Distribution  Date,  will  be an  amount  equal  to the  sum  of the  Interest
Amount:                         Distribution  Amount for the Class A Certificates  for such  Distribution  Date and the Interest
                                Carry Forward Amount, if any, for the Class A Certificates for such Distribution Date.

Administration Fee Rate:        The Master  Servicer,  the Servicer and the Credit Risk Manager will be paid monthly fees on the
                                outstanding  principal  balance  of the  Mortgage  Loans.  These fees (the  "Administration  Fee
                                Rate")  initially  aggregate to a weighted average  servicing fee of  approximately  0.5300% per
                                annum.

Compensating Interest:          The Servicer will be required to cover Prepayment  Interest Shortfalls on prepayments in full on
                                the  Mortgage  Loans  received  during the related  Prepayment  Period up to the  Servicing  Fee
                                payable to the Servicer.  If the 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 Loans.

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 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 Servicer
                                 fails to exercise such purchase option,  the Master Servicer may, subject to certain  conditions
                                 set forth in the pooling and servicing  agreement,  exercise such purchase option.  In the event
                                 that the Master  Servicer  fails to  exercise  such  purchase  option,  the Class A  Certificate
                                 Insurer may,  subject to certain  conditions  set forth in the pooling and servicing  agreement,
                                 exercise  such  purchase  option.  In the event that  either  the  Servicer  or Master  Servicer
                                 exercises  the  Optional  Termination,  such  party  must  obtain  the  consent  of the  Class A
                                 Certificate  Insurer if (i) any amounts are owed to the Class A Certificate  Insurer or (ii) the
                                 Optional  Termination  would  result in a draw on the policy  issued by the Class A  Certificate
                                 Insurer.  In the event  either the  Servicer,  Master  Servicer or Class A  Certificate  Insurer
                                 exercises this option,  the portion of the purchase price allocable to the certificates will be,
                                 to the  extent  of  available  funds,  (i) 100% of the then  outstanding  Certificate  Principal
                                 Balance of the certificates,  plus (ii) one month's interest on the then outstanding Certificate
                                 Principal  Balance of the  certificates at the then applicable  pass-through  rate for each such
                                 class,  plus (iii) any previously  accrued but unpaid  interest  thereon to which the holders of
                                 the certificates are entitled, together with the amount of any Net WAC Rate Carryover Amounts.

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 but only to the extent such amounts are deemed  recoverable.  If the Servicer  fails to
                                make  any  such  advances,  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  these  advances,  and  therefore  these  advances  are  not a  form  of  credit
                                enhancement.

Credit Enhancement:             1) Excess Interest;

                                3) Subordination; and
                                4) Certificate Guaranty Insurance Policy.

Certificate Guaranty            The Class A Certificates  will have the benefit of a financial  guaranty  insurance  policy (the
Insurance Policy:               "Certificate  Guaranty Insurance Policy") pursuant to which the Class A Certificate  Insurer, in
                                consideration  of the payment of a premium and subject to the terms of the Certificate  Guaranty
                                Insurance  Policy,  will  guarantee  the  monthly  payment of  principal  and  current  interest
                                shortfalls on the Class A Certificates,  except  shortfalls and losses resulting from prepayment
                                interest shortfalls,  Relief Act shortfalls and Net WAC Rate Shortfalls. The Class A Certificate
                                Insurer's  claims  paying  ability is rated  "AAA",  "AAA" and "Aaa" by S&P,  Fitch and Moody's,

  Allocation of Losses:          Any Realized  Losses on the Mortgage Loans will,  first,  reduce the Net Monthly  Excess  Cashflow
                                 available   to   make   payments   to   the    Certificateholders    and,   second,   reduce   the
                                 Overcollateralization  Amount. If on any Distribution  Date, after all  distributions  (other than
                                 payments under the Certificate  Guaranty  Insurance  Policy) are made to  Certificateholders,  the
                                 aggregate  principal  balance of the Certificates  exceeds the aggregate  principal balance of the
                                 Mortgage Loans  outstanding,  such excess will be allocated first, to the Class M-4  Certificates,
                                 second,  to the Class M-3  Certificates,  third to the Class M-2 Certificates  and fourth,  to the
                                 Class M-1  Certificates.  To the extent that remaining  excess  exists,  a payment of principal in
                                 that amount will be made under the Certificate  Guaranty  Insurance  Policy for the benefit of the
                                 Class A Certificateholders.

                                 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  (except in the case of  subsequent  recoveries).  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  or from  any Net Swap  Payments  payable  by the Swap  Provider
                                 available for this purpose.

                                 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 net  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 Servicer
                                 has  determined  that it has  received all amounts it expects to receive in  connection  with such
                                 liquidation,  including  payments under any 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  Servicer is required to
                                 charge off once such  Mortgage Loan becomes 180 days  delinquent  provided that such Mortgage Loan
                                 has not yet been liquidated.

Required                        Overcollateralization  refers to the  amount  by which the  aggregate  principal  balance  of the
Overcollateralization           Mortgage Loans exceeds the aggregate  Certificate  Principal  Balance of the certificates  (other
Amount:                         than the Class CE  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 fully established at

                                the  aggregate  principal  balance of the  Mortgage  Loans as of the  Cut-off  Date,  and (B) the

                                approximately  1.90% and (ii) the  aggregate  principal  balance of the Mortgage  Loans as of the
                                last day of the related Due Period and (B) the cumulative  amount of Net Monthly Excess  Cashflow

                                Priority" on all prior Distribution  Dates,  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, Net Monthly Excess Cashflow,  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.

Overcollateralization           An  "Overcollateralization  Increase Amount" for any Distribution  Date will be the lesser of (i)
Increase Amount:                the sum of the Net  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  after  taking into
                                account all other  distributions to be made on the Distribution Date limited to the distributions
                                made with funds paid as principal payments on the Mortgage Loans.

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
                                distributions made with funds paid as principal payments on the Mortgage Loans.

Stepdown Date:                  Will be the earlier of (i) the first  Distribution Date following the Distribution Date which the
                                Certificate  Principal  Balances  of the Class A  Certificates  are  reduced to zero and (ii) the
                                later to occur of (x) the Distribution Date occurring in May 2010 and (y) the first  Distribution
                                Date on which the Class A 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  certificates)  is equal to or  greater  than
                                approximately 29.00%.

Credit Enhancement Percentage:  The Credit  Enhancement  Percentage for any class of certificates  and any  Distribution
                                Date is the percentage  obtained by dividing (x) the aggregate  Certificate  Principal Balance of
                                the classes  subordinate  to such class  (which  includes  the Class CE  Certificate)  by (y) the
                                aggregate  principal  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  Certificates  then
                                entitled to distributions of principal on the Distribution Date.

                               under  "Payment  Priority",  (y) any Net Swap  Payment or the Swap  Termination  Payment  (not
                               caused by a Swap Provider  Trigger Event (as defined in the Swap  Agreement)) owed to the Swap

                               and reimbursement amounts.

 Net WAC Pass-Through Rate:    For Class A and Subordinate  Certificates,  the Net WAC Pass-through  Rate will equal 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  difference  of (a) the amount of interest  which
                               accrued  on the  Mortgage  Loans in the  prior  calendar  month  minus  the  fees,  expenses,
                               indemnities and/or reimbursements  payable to the Servicer,  the Master Servicer,  the Credit

                               prepayments received during the related Prepayment Period.

 Net WAC Rate Carryover        If on any Distribution  Date the Pass-Through  Rate for any class of Certificates is
 Amount:                       limited by the Net WAC  Pass-Through  Rate,  such class 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,  and  from  the  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.
                               The ratings on each class of Offered  Certificates  will not address  the  likelihood  of the
                               payment of any Net WAC Rate Carryover Amount from Net Monthly Excess Cashflow.

                                           Transaction Overview (Cont.)
-----------------------------------------------------------------------------------------------------------------------------------
 Swap Agreement:               On the Closing  Date,  the 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  $335,803,000.  Beginning  with  the  Distribution  Date in May  2007,  the  trust
                               (through a  supplemental  interest  trust) will be  obligated  to pay an amount  equal to the
                               product of (i) 5.065% 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.

 Available Distribution        For any Distribution  Date, net of the  administration  expenses and amounts  reimbursable to
 Amount:                       the Servicer,  Master  Servicer,  Trust  Administrator  and the Trustee under the Pooling and
                               Servicing  Agreement,  an  amount  equal to (i) the  aggregate  amount of  scheduled  monthly
                               payments on the  Mortgage  Loans due on the related Due Date and  received on or prior to the
                               related  Determination  Date;  (ii)  unscheduled  payments in respect of the  Mortgage  Loans
                               (including prepayments,  insurance proceeds,  liquidation proceeds, subsequent recoveries and
                               proceeds from  repurchases of and  substitutions  for the Mortgage Loans occurring during the
                               Prepayment  Period or proceeds from the  repurchase of the Mortgage Loans due to the Optional
                               Termination  of the  Trust);  (iii) all P&I  Advances  with  respect  to the  Mortgage  Loans
                               received for the Distribution  Date; and (iv) all Compensating  Interest paid by the Servicer
                               or Master Servicer in respect of Prepayment  Interest  Shortfalls for the related  Prepayment
