The analysis in this report is based on information provided by Ace Securities
Corp. (the "Seller"). Deutsche Banc Alex. Brown Inc. ("DBAB") makes no
representations as to the accuracy or completeness of the information contained
herein. The information contained herein is qualified in its entirety by the
information in the Prospectus and Prospectus Supplement for this transaction.
The information contained herein is preliminary as of the date hereof,
supersedes any previous information delivered to you by DBAB and will be
superseded by the applicable final Prospectus and Prospectus Supplement and any
other information subsequently filed with the Securities and Exchange
Commission. These materials are subject to change, completion, or amendment from
time to time without notice, and DBAB is under no obligation to keep you advised
of such changes. These materials are not intended as an offer or solicitation
with respect to the purchase or sale of any security. Any investment decision
with respect to the securities should be made by you based upon the information
contained in the final Prospectus Supplement and Prospectus relating to the
securities. 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 DBAB in reliance
upon information furnished by the Seller. They may not be provided to any third
party other than the addressee's legal, tax, financial and/or accounting
advisors for the purposes of evaluating said material. Numerous assumptions were
used in preparing the Computational Materials which may or may not be reflected
herein. As such, no assurance can be given as to the Computational Materials'
accuracy, appropriateness or completeness in any particular context; nor 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 due to differences between the
actual underlying assets and the hypothetical underlying assets used in
preparing the Computational Materials. The principal amount and designation of
any security described in the Computational Materials are subject to change
prior to issuance. Neither DBAB 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.

THIS INFORMATION IS FURNISHED TO YOU SOLELY BY DBAB AND NOT BY THE ISSUER OF THE
SECURITIES OR ANY OF ITS AFFILIATES (OTHER THAN DBAB). DBAB IS ACTING AS
UNDERWRITER AND NOT ACTING AS AGENT FOR THE ISSUER IN CONNECTION WITH THE
PROPOSED TRANSACTION.

                                 Distribution  Date to (but excluding) the current  Distribution  Date on an actual/360 basis.
                                 These  Certificates  will initially  settle flat (no accrued  interest).  The Class A-IO will
                                 accrue  interest  during the  calendar  month  immediately  preceding  the month in which the
                                 Distribution Date occurs on a 30/360 basis (19 day delay).

PREPAYMENT ASSUMPTION:           The Class A and Class M  Certificates  will be priced  assuming a 28% CPR throughout the life
                                 of the collateral.

ADMINISTRATIVE FEES:             The Master  Servicer,  Sub-Servicers,  Loss  Mitigation  Advisor and Custodians  will be paid
                                 monthly  fees on the  outstanding  principal  balance of the  Mortgage  Loans.  The  Mortgage
                                 Insurer  will be paid  monthly  fees on the  outstanding  principal  balance  of the  insured
                                 Mortgage  Loans   (approximately   [73.11%]  of  all  of  the  Mortgage  Loans).  These  fees
                                 ("Administrative  Fees"),  including the mortgage insurance premium initially  aggregate to a
                                 weighted average cost of approximately [150.18%] basis points for 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  sum of 10% of  their
                                 aggregate  outstanding  principal  balance as of the Cut-off Date, the owner of a non-offered
                                 subordinate  certificate  will have the  option  to  purchase  from the  trust all  remaining
                                 mortgage loans causing an early retirement of the certificates;  provided,  however,  that if
                                 the owner of such  non-offered  subordinate  certificate is an affiliate of the Seller,  such
                                 owner  will not have the  option to  purchase  from the trust all  remaining  mortgage  loans
                                 causing an early retirement of the certificates.

CREDIT ENHANCEMENT:              1) Mortgage insurance
                                 2) Excess interest

                                 4) Subordination

MORTGAGE INSURANCE:              As of the Cut-off  Date,  approximately  [73.11%] of the Mortgage  Loans will be covered by a
                                 lender-paid  mortgage  insurance  policy issued by Mortgage  Guaranty  Insurance  Corporation
                                 ("MGIC").  MGIC will  provide  insurance  coverage  down to 50% of the  value of the  related

OVERCOLLATERALIZATION:           Overcollateralization  refers to the amount by which the aggregate  principal  balance of the
                                 Mortgage Loans exceeds the certificate  principal  balance of the  certificates.  This excess
                                 (the  "Overcollateralization  Amount") is intended to protect the certificate holders against
                                 shortfalls in payments on the  certificates.  The required  Overcollateralization  Amount for
                                 the Certificates,  which will be fully established at issuance,  is anticipated to be [0.50]%
                                 of the  original  pool  balance.  If,  due to  losses,  the  Overcollateralization  Amount is
                                 reduced below  [0.50]%,  excess  spread,  if any is  available,  will be applied to first pay
                                 Class  A  principal,  and  then  Class  M  principal,  in  order  to  maintain  the  required
                                 Overcollateralization Amount.

OVERCOLLATERALIZATION            After the Stepdown  Date, the  overcollateralization  amount will be allowed to be reduced to
STEPDOWN:                        [1.00]%  of  the  then  current  balance  of  the  mortgage  pool,  subject  to  a  floor  of
                                 $[3,695,698], but only in the event that a Trigger Event has not occurred.

OVERCOLLATERALIZATION INCREASE   On any  Distribution  Date, any amount of Net Monthly Excess Cashflow  actually applied as an
AMOUNT:                          accelerated  payment of  principal to the extent the  required  Overcollateralization  Amount
                                 exceeds the current Overcollateralization Amount.

OVERCOLLATERALIZATION            With respect to each such Distribution  Date, the Group I Principal  Distribution  Amount and
REDUCTION AMOUNT:                the Group II Principal  Distribution  Amount will each be reduced by an allocated  portion of
                                 the  amount  by  which  the  current   Overcollateralization   Amount  exceeds  the  required
                                 Overcollateralization Amount

INITIAL CREDIT ENHANCEMENT       The Credit  Enhancement  Percentage for any class and any Distribution Date is the percentage
PERCENTAGE:                      obtained by dividing (x) the aggregate  Certificate Principal Balance of the class or classes
                                 subordinate thereto by (y) the aggregate principal balance of the Mortgage Loans,  calculated
                                 after taking into account  distributions  of principal on the Mortgage Loans and distribution
                                 of the  Principal  Distribution  Amount to the holders of the  certificates  then entitled to
                                 distributions of principal on the Distribution Date.

                                             CLASS                        RATING                          PERCENT
                                             -----                        ------                          -------
                                                                                                 
                                        A-1, A-2, A-IO                Aaa / AAA / AAA                     [6.00]%
                                              M-1                      Aa2 / AA / AA                      [3.00]%
                                              M-2                       A2 / A / A                        [1.50]%

BASIS RISK SHORTFALL:            Because the mortgage rates are either fixed rate,  based on 6 month LIBOR, or based on 1 year
                                 CMT, and some loans may have delayed first  adjustments,  and the  pass-through  rates on the
                                 Offered  Certificates  are  based  on  one  month  LIBOR,  the  limitations  of the  Net  WAC
                                 Pass-Through  Rate could result in  shortfalls of interest  otherwise  payable to the Offered
                                 Certificates  in  certain  periods.  This may also occur if 6 month  LIBOR and 1 month  LIBOR
                                 rise quickly  since the Mortgage  Pool cash flows are  constrained  by interim caps. If basis
                                 risk interest  shortfalls  occur,  they will be carried forward at their  applicable rate and
                                 such shortfalls will be paid on a subordinated  basis on the same Distribution Date or in any
                                 subsequent period.  Such shortfalls will accrue interest at the related pass-through rate.

STEPDOWN DATE:                   Is the  earlier  of (i) the  first  Distribution  Date on  which  the  Certificate  Principal
                                 Balances of the Class A  Certificates  have been  reduced to zero and (ii) the later to occur
                                 of (x) the Distribution  Date occurring in December 2004 and (y) the first  Distribution Date
                                 on which the 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 the  Principal  Distribution  Amount to the holders of the  Certificates  then entitled to
                                 distributions  of  principal  on  such  Distribution  Date)  is  greater  than  or  equal  to
                                 approximately [12.00]%.

                                 occurred,  will have the effect of accelerating  the amortization of the Class A Certificates
                                 while, in the absence of Realized Losses,  increasing the respective  percentage  interest in
                                 the  principal  balance of the  Mortgage  Loans  evidenced by the  Subordinate  Certificates.
                                 Increasing the respective  percentage  interest in the Trust of the Subordinate  Certificates
                                 relative to that of the Class A Certificates is intended to preserve the  availability of the

                                 increase  [100]% and the margins on the Class M-1, M-2 and M-3 coupon will increase by [50]%,
                                 subject to the Net WAC Pass-Through Rate.

SERVICING ADVANCES:              The  Sub-servicers  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 and then remit such collections and any required  delinquency advances to the Master
                                 Servicer.  The Master  Servicer will be obligated to make any required  delinquency  advances
                                 if the  applicable  Sub-servicer  fails in its  obligation to do so. The Master  Servicer and
                                 Sub-servicers  are required to advance  delinquent  payments of principal and interest on the
                                 mortgage loans only to the extent such amounts are deemed  recoverable.  The Master  Servicer
                                 Sub-servicers are entitled to be reimbursed for these advances,  and therefore these advances
                                 are not a form of credit enhancement.
