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 (econometric 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 information (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 
modelling 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 at 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.

                   CERTIFICATE STRUCTURE SUMMARY (CONTINUED)


    REPRESENTATIONS AND        The Mortgage Loan Seller will make certain
    WARRANTIES:                representations and warranties with respect to
                               each Mortgage Loan. See pages S-63 through S-72
                               of the preliminary Prospectus Supplement.

    SERVICER ADVANCING:        The Servicer will be required to make (i) P & I
                               Advances (excluding principal Balloon Payments
                               and any excess interest on the ARD Loan) and
                               (ii) Servicing Advances, in each case through
                               liquidation of the related Mortgage Loan, unless
                               such Advances are determined by the Servicer to
                               be Nonrecoverable Advances. In addition, P & I
                               Advances may be reduced for any Appraisal
                               Reductions that may occur (see section below).
                               See pages S-85 through S-88 of the preliminary

                               other events. An Appraisal Reduction may result,
                               which would have the effect of reducing the
                               amount of P & I Advances made by the Servicer
                               and the voting rights of the most subordinate

                               of the preliminary Prospectus Supplement.

    DEFEASANCE:                The terms of 95.9% of the Mortgage Loans grant
                               the related borrower the right at any time

                               collateral for the related Mortgage Note, U.S.
                               Treasury securities which provide for payments
                               on or prior to each Due Date and the maturity
                               date or Anticipated Repayment Date, as the case
                               may be, of amounts at least equal to the amounts
                               which would have been payable on each such date
