STATEMENT REGARDING ASSUMPTIONS AS TO SECURITIES, PRICING ESTIMATES, AND OTHER
INFORMATION

The information contained in the attached materials (the "Information") may
include various forms of performance analysis, security characteristics and
securities pricing estimates for the securities addressed. Please read and
understand this entire statement before utilizing the Information. The
Information is provided solely by Bear Stearns, not as agent for any issuer, and
although it may be based on data supplied to it by an issuer, the issuer has not
participated in its preparation and makes no representations regarding its
accuracy or completeness. Should you receive Information that refers to the
"Statement Regarding Assumptions and Other Information," please refer to this
statement instead.

The Information is illustrative and is not intended to predict actual results
which may differ substantially from those reflected in the Information.
Performance analysis is based on certain assumptions with respect to significant
factors that may prove not to be as assumed. You should understand the
assumptions and evaluate whether they are appropriate for your purposes.
Performance results are based on mathematical models that use inputs to
calculate results. As with all models, results may vary significantly depending
upon the value of the inputs given. Inputs to these models include but are not
limited to: prepayment expectations (economic prepayment models, single expected
lifetime prepayments or a vector of periodic prepayments), interest rate
assumptions (parallel and nonparallel changes for different maturity
instruments), collateral assumptions (actual pool level data, aggregated pool
level data, reported factors or imputed factors), volatility assumptions
(historically observed or implied current) and reported (paydown factors, rate
resets, and trustee statements). Models used in any analysis may be proprietary
making the results difficult for any third party to reproduce. Contact your
registered representative for detailed explanations of any modeling techniques
employed in the Information.

The Information addresses only certain aspects of the applicable security's
characteristics and thus does not provide a complete assessment. As such, the
Information may not reflect the impact of all structural characteristics of the
security, including call events and cash flow priorities at all prepayment
speeds and/or interest rates. You should consider whether the behavior of these
securities should be tested as assumptions different from those included in the
Information. The assumptions underlying the Information, including structure and
collateral, may be modified from time to time to reflect changed circumstances.
Any investment decision should be based only on the data in the prospectus and
the prospectus supplement or private placement memorandum (Offering Documents)
and the then current version of the Information. Offering Documents contain data
that is current as of their publication dates and after publication may no
longer be complete or current. Contact your registered representative for
Offering Documents, current Information or additional materials, including other
models for performance analysis, which are likely to produce different results,
and any further explanation regarding the Information.

Any pricing estimates Bear Stearns has supplied at your request (a) represent
our view, at the time determined, of the investment value of the securities
between the estimated bid and offer levels, the spread between which may be
significant due to market volatility or illiquidity, (b) do not constitute a bid
by any person for any security, (c) may not constitute prices at which the
securities could have been purchased or sold in any market, (d) have not been
confirmed by actual trades, may vary from the value Bear Stearns assigns any
such security while in its inventory, and may not take into account the size of
a position you have in the security, and (e) may have been derived from matrix
pricing that uses data relating to other securities whose prices are more
readily ascertainable to produce a hypothetical price based on the estimated
yield spread relationship between the securities.

GENERAL INFORMATION: The data underlying the Information has been obtained from
sources that we believe are reliable, but we do not guarantee the accuracy of
the underlying data or computations based thereon. Bear Stearns and/or
individuals thereof may have positions in these securities while the Information
is circulating or during such period may engage in transactions with the issuer
or its affiliates. We act as principal in transactions with you, and
accordingly, you must determine the appropriateness for you of such transactions
and address any legal, tax, or accounting considerations applicable to you. Bear
Stearns shall not be a fiduciary or advisor unless we have agreed in writing to
receive compensation specifically to act in such capacities. If you are subject
to ERISA, the Information is being furnished on the condition that it will not
form a primary

basis for any investment decision. The Information is not a solicitation of any
transaction in securities which may be made only by prospectus when required by
law, in which event you may obtain such prospectus from Bear Stearns.

                               their own counsel with respect to an investment
                               in the offered Certificates.

SMMEA TREATMENT:               The Class AF Certificates will not constitute
                               "mortgage-related securities" for purposes of
                               SMMEA, while the Class AV Certificates will
                               constitute "mortgage-related securities" for
                               purposes of SMMEA.

TAX STATUS:                    REMIC under the Internal Revenue Code.

                          CREDIT ENHANCEMENT

EXCESS INTEREST:               Excess Interest  cashflows from each loan group
                               will be available as credit  enhancement for the
                               related loan group.

OVERCOLLATERALIZATION:         The  credit  enhancement  provisions  of the Trust
                               are intended to provide for the limited
                               acceleration of the Certificates relative to the
                               amortization of the related collateral pool,
                               generally in the early months of the transaction.
                               Accelerated amortization is achieved by applying
                               certain excess interest collected on the
                               collateral to the payment of principal on the
                               related Certificates resulting in the build up of
                               overcollateralization ("O/C"). By paying down the
                               principal balance of the Certificates faster than
                               the principal amortization of the respective loan
                               group, an O/C amount equal to the excess of the
                               aggregate principal balance of the collateral
                               over the principal balance of the related
                               Certificates is created. Excess cash flows will
                               be directed to build each O/C amount until the
                               respective Mortgage Loan Group reaches its
                               required O/C target. Upon this event, the
                               acceleration feature will cease, unless it is
                               once again necessary to maintain the required O/C
                               level.

                               group, will be available to credit enhance the
                               other group.

FSA INSURANCE POLICY:          FSA (the "Certificate  Insurer") will
                               unconditionally and irrevocably guarantee the
                               timely payment of interest and ultimate payment
                               of principal on the Certificates (i.e. after any

                               groups). The Insured Payments do not cover
                               Realized Losses except to the extent that an
                               Overcollateralization Deficit exists. Insured
                               Payments do not cover the Servicer's failure to

                               that an Overcollateralization Deficit would
                               otherwise result therefrom. The Insurance Policy
                               is not cancelable for any reason.

FIXED RATE AFC:                All fixed rate coupons are subject to the
                               fixed-rate available funds cap ("Fixed Rate
                               AFC"). The Fixed-Rate AFC is a rate equal to the
                               weighted average gross coupon rate for the
                               Fixed-Rate Group collateral less the servicing
                               fee (50 bps) and the trustee fee (1 bp).

ADJUSTABLE RATE AFC:           All adjustable rate coupons are subject to the
                               adjustable-rate available funds cap ("Adjustable
                               Rate AFC"). The Adjustable-Rate AFC is a rate
                               equal to the weighted average gross coupon rate
                               for the Adjustable-Rate Group collateral less the
                               servicing fee (50 bps), the trustee fee (1 bp)
                               and 50 bps.

INTEREST ACCRUAL:              For the Fixed-Rate Certificates, interest will
                               accrue from the 1st day of the preceding month
                               until the 30th day of that month. For the
                               Adjustable-Rate Certificates, interest will
                               accrue for the first accrual period from the
                               Closing Date and, thereafter, from the preceding
                               Payment Date until the business day preceding the
                               current Payment Date.

PAYMENT DELAY:                 Fixed-Rate Certificates:           24 days
                               Adjustable-Rate Certificates:       0 days

CLEAN-UP CALL:                 The Master Servicer has the option to exercise a
                               call when the aggregate Stated Principal Balance
                               of the mortgage loans is less than or equal to
                               10% of the Aggregate Stated Principal Balance of
                               the mortgage loans as of the Cut-Off Date. The
                               call will be exercised at par plus accrued
                               interest.

COUPON STEP UP:                FIXED RATE CERTIFICATES:
                               If the 10% Clean-Up Call is not exercised, the
                               Class AF coupon shall increase by 50 bps.

                               ADJUSTABLE RATE CERTIFICATES:
                               If the 10% Clean-Up Call is not exercised, the
                               Class AV margin will double.

SHORTFALL REIMBURSEMENT:       If on any Payment Date the Pass-Through Rate on the
                               Adjustable-Rate Certificates is limited by the
                               Adjustable-Rate AFC, the amount of such interest
                               that would have been distributed if the
                               Pass-Through Rate had not been so limited over
                               the amount of interest at the Adjustable-Rate AFC
                               and the aggregate of such shortfalls from
                               previous Payment Dates together with accrued
                               interest at the Pass-Through Rate will be carried
                               forward to the next Payment Date until paid. No
                               interest carryforward will be paid once the
                               related Certificate principal balance has been
                               reduced to zero.
