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, ▇▇▇▇▇▇▇ & Co. Inc. ("Bear ▇▇▇▇▇▇▇"), 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 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 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 ▇▇▇▇▇▇▇ 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 ▇▇▇▇▇▇▇ 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 ▇▇▇▇▇▇▇ 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
▇▇▇▇▇▇▇ 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 ▇▇▇▇▇▇▇.

Class A-2; one-month LIBOR+0.35% for the Class M-1; one-month LIBOR+0.58%
for the Class M-2; and one-month LIBOR+1.17% for the Class B. For
collateral modeling purposes, six-month LIBOR was assumed to be 5.71875%.
--------------------------------------------------------------------------------
THE CERTIFICATES:
The Certificates are backed by six-month LIBOR-indexed, "2/28," "3/27" and
"5/25" conventional, adjustable-rate mortgage loans.
All Classes are priced to call.
Classes are payable monthly starting 10/20/98; the floating-rate Certificates
pay on an Actual/360 basis and the fixed-rate Class A-IO Certificates pay on a
30/360 basis.
Floating-rate Classes reset monthly to one month LIBOR plus their respective
margins subject to the available funds cap with no delay.
Optional call is 10% of the Assumed Pool Principal Balance. Step function is
subject to available funds cap. If the loans are not called, the Certificate
Margin of the Class A-1 and Class A-2 Certificates will increase by a multiple
of 2X and the Certificate Margin of the Subordinate Certificates will increase
by a multiple of 1.5X. Adjustable-rate mortgage loans pricing speeds: 25%
constant CPR.
The applicable Pass-through Rate with respect to the Class A-IO Certificates is
equal to 5.50% for the first 12 Distribution Dates, 4.00% for the 13th through
the 24th Distribution Dates, 2.50% for the 25th through the 30th Distribution
Dates, and 0.00% thereafter. The Class A-IO Certificates will be divided into
three components, which are not separately transferable as distinct securities.
STRUCTURE SUMMARY:
Credit enhancement is provided using excess cash, overcollateralization and
subordination. The initial Overcollateralization Amount is equal to 0.00% of the
sum of the Cut-off Date Pool Principal Balance and the Original Pre-funded
Amount. The Required Overcollateralization Amount is equal to 3.85% of the
Cut-off Date Pool Principal Balance and the Original Pre-funded Amount.
On each Distribution Date (a) before the Stepdown Date or (b) with respect to
which a Trigger Event is in effect, the Principal Distribution Amount will be
distributed sequentially to the Class A-1, the Class A-2, the Class M-1, the
Class M-2 and the Class B Certificates, in that order, until each Certificate
Principal Balance of each such class has been reduced to zero.
Following the occurrence of the Stepdown Date and so long as no Trigger Event is
in effect, the Class A-1 and the Class A-2 Certificates will sequentially
receive 100% of the Principal Distribution Amount until the Required
Overcollateralization Amount is reached. At the point when this event occurs,
the Class B Certificates will have 7.7% subordination, the Class M-2
Certificates will have 19.7% subordination, the Class M-1 Certificates will have
33.7% subordination and the Class A-1 and A-2 Certificates will have 49.7%
subordination. The Certificates will be paid in the proper proportions to keep
these subordination levels in line until the Overcollateralization Amount
reaches a floor equal to 0.50% of the sum of the Cut-off Date Pool Principal
Balance and the Original Pre-funded Amount. At and after that point, the
Overcollateralization Amount will remain constant at the floor.
The Class C Certificates and the Residual Certificates, which are not offered,
will get all excess cash, if any, on each Distribution Date after payment to the
Class A-IO, Class A-1, Class A-2, Class M-1, Class M-2 and Class B of all
amounts to which they are entitled.

INTEREST
CALCULATION: The Offered Certificates are payable monthly
starting October 20, 1998. The Offered
Certificates other than the Class A-IO
Certificates (the "Floating-rate
Certificates") accrue interest monthly on an
actual/360 basis. The Pass-through Rate for
the Floating-rate Certificates will be equal
to the lesser of (i) One-Month LIBOR plus
their respective margins in the case of each
Distribution Date up to the Distribution
Date on which the aggregate principal
balance of the Mortgage Loans is reduced to
10% or less of the Assumed Pool Principal
Balance (as defined herein), or One-Month
LIBOR plus their respective higher margins,
in the case of any Distribution Date
thereafter or (ii) the Available Funds Cap
(as defined herein). The applicable Interest
Accrual Period with respect to each
Distribution Date and class of Floating-rate
Certificates is the Period from the
Distribution Date in the month preceding the
month of such Distribution Date (or, in the
case of the first Distribution Date, from
the Closing Date) through the day before
such Distribution Date.
On each Distribution Date, the holders of
the Class A-IO Certificates will be entitled
to receive, to the extent of amounts
available for distributions as described
herein, interest distributions in an amount
equal to the sum of (i) interest accrued for
the related Interest Accrual Period on the
Notional Amount (as defined herein) thereof
immediately prior to such Distribution Date
at the then-applicable Pass-through Rate
(based on a 30/360 basis). The applicable
Interest Accrual Period with respect to the
Class A-IO Certificates is the calendar
month preceding the related Distribution
Date. The applicable Pass-through Rate with
respect to the Class A-IO Certificates is
equal to 5.50% for the first 12 Distribution
Dates, 4.00% for the 13th through the 24th
Distribution Dates, 2.50% for the 25th
through the 30th Distribution Dates, and
0.00% thereafter. The "Notional Amount" for
the Class A-IO Certificates will be equal to
10% of the aggregate Certificate Principal
Balances of the Floating-rate Certificates
as of the Closing Date.
AVAILABLE FUNDS CAP: The Floating-rate Certificates will be
subject to an Available Funds Cap equal to
the weighted average of the rates on the
Mortgage Loans as of the second day of the
month preceding the month of such
Distribution Date less an amount equal to
the sum of the Servicing Fee Rate and the
applicable Pass-through Rate with respect to
the Class A-IO Certificates.
AVAILABLE FUNDS CARRYOVER: If on any Distribution Date, the
Pass-Through Rate for a Floating-rate
Certificate is based on the Available Funds
Cap, holders of such Certificates will be
entitled to receive the available funds cap
carryover amount on future Distribution
Dates, subject to available funds.

PRINCIPAL ALLOCATION: Principal distribution amounts will be
allocated to holders of Floating-rate
Certificates (holders of Class A-IO
Certificates will not be entitled to
distributions with respect to principal) on
each Distribution Date in the following
priority:
FOR PERIODS PRIOR TO THE STEPDOWN DATE (AS
DEFINED HEREIN) OR WHILE A TRIGGER EVENT (AS
DEFINED HEREIN) EXISTS:
1. To the Class A-1 Certificates,
100% of the principal
distribution amount until the
principal balance thereof is
equal to zero;
2. Thereafter, to the Class A-2
Certificates, 100% of the
principal distribution amount
until the principal balance
thereof is equal to zero;
3. The balance, if any, of the
principal distribution amount
shall be distributed to the
Class M-1, Class M-2 and Class
B Certificates, in that order,
in each case, until the
corresponding principal balance
has been reduced to zero; and
4. Any amount remaining shall be
included as part of the net
monthly excess cash flow to
cover shortfalls and other
amounts.
FOR PERIODS ON AND AFTER THE STEPDOWN DATE
AND WHILE NO TRIGGER EVENT EXISTS:
1. To the Class A-1 Certificates,
an amount required to reach and
maintain the credit enhancement
target for the Class A-1
Certificates;
2. To the Class A-2 Certificates,
an amount required to reach and
maintain the credit enhancement
target for the Class A-2
Certificates;

--------------------------------------------------------------------------------
5. To the Class B Certificates, an
amount required to reach and
maintain the credit enhancement
target for the Class B
Certificates; and
6. Any amount remaining shall be
included as part of the net
monthly excess cash flow to
cover shortfalls and other
amounts.
Notwithstanding the foregoing, on
any Distribution Date on which the
sum of (i) the principal balances of
the Subordinate Certificates and
(ii) the overcollateralization
amount is reduced to zero, any
amounts of principal payable to the
Class A-1 and Class A-2 Certificates
shall be distributed pro rata.
A "Trigger Event" is in effect if on any
Distribution Date the percentage obtained by
dividing (x) the aggregate Stated Principal
Balance (as defined herein) of the Mortgage
Loans that are 60 or more days delinquent in
payment of principal and interest as of the
last day of the preceding calendar month, by
(y) the Pool Principal Balance (as defined
herein) as of the last day of the preceding
calendar month, equals or exceeds 35% of the
Senior Enhancement Percentage. "Senior
Enhancement Percentage" for any Distribution
Date is the percentage obtained by dividing
(x) the sum of the aggregate Certificate
Principal Balance of the Subordinates (or if
the Certificate Principal Balance of the
Class A Certificate has been reduced to
zero, the aggregate Certificate Principal
Balance of each Class of Subordinate
Certificates other than the most senior
Class of Subordinate Certificates then
outstanding) and (ii) the
Overcollateralization Amount after taking
into account the distribution of the related
Principal Distribution Amount on such
Distribution Date by (y) the sum of (i) the
aggregate Loan Balance of the Mortgage Loans
as the last day of the related Due Period
and (ii) the Pre-funded Amount as to the
last day of the related Due Period.
The "Stated Principal Balance" of a Mortgage
Loan as of any date of determination is
equal to the unpaid principal balance
thereof at the close of business on the
Cut-off Date or subsequent Cut-off Date,
reduced by all amounts that are allocable to
principal that have been distributed to
Certificateholders with respect to such
Mortgage Loan and as further reduced to the
extent of any realized loss incurred with
respect to such Mortgage Loan or on before
the last day of the most recently ended due
period. With respect to any date, the "Pool
Principal Balance" will be equal to the
aggregate Stated Principal Balance of all
Mortgage Loans included in the Trust as of
such date.
PRICING PREPAYMENT
SPEED ASSUMPTION: Constant at 25.0% CPR.
MORTGAGE
LOANS: The "Initial Mortgage Loans," as of the
Statistical Calculation Date, with remaining
terms to maturity ranging from approximately
180 months to 360 months, consist of 5,863
Mortgage Loans with an approximate balance of
$600,413,234.52. 685 six-month LIBOR indexed,
5,051 "2/28" adjustable-rate, 125 "3/27"
adjustable-rate and 2 "5/25" adjustable-rate
conventional, fully amortizing, first lien,
closed end, one- to four-family residential

Additional Mortgage Loans originated or
acquired prior to the Closing Date (the
"Additional Mortgage Loans") will also be
included in the assets of the Trust. It is
anticipated that the aggregate principal
balance of the Additional Mortgage Loans as
of the Cut-off Date will not exceed
$80,000,000. The "Initial Pool Principal
Balance" is defined as the sum of the
principal balances of the Initial Mortgage
Loans and the Additional Mortgage Loans as of
the Closing Date. The Initial Pool Principal
Balance is subject to a permitted variance of
5%+/-.
PRE-FUNDING FEATURE: An amount equal to the excess of the
Aggregate Certificate Principal Balance over
the Initial Pool Principal Balance plus the
overcollateralization amount (the "Original
Pre-funded Amount") will be deposited on the
Closing Date for the acquisition of Mortgage
Loans (the "Subsequent Mortgage Loans")
during a 90 day period following the Closing
Date. Any amount not so used will be
distributed to the holders of the Class A-1
Certificates. It is anticipated that the
Original Pre-funded Amount will be
approximately $120,000,000, which will be
deposited in a Pre-funding Account.
ASSUMED POOL PRINCIPAL
BALANCE: The sum of (i) the Initial Pool Principal
Balance and (ii) the amount deposited in the
Pre-funding Account. This amount represents
the approximate final pool of Mortgage Loans
for the transaction, after amounts in the
Pre-funding Account have been used to
purchase Subsequent Mortgage Loans as
described under the caption "Pre-funding
Feature" above.
STEPDOWN DATE: The "Stepdown Date" means the latter to occur
of:
1) The Distribution Date in October 2001
(i.e. on the 37th Distribution Date);
and
2) The first Distribution Date on which the
Senior Enhancement Percentage is greater
than or equal to the Senior Specified
Enhancement Percentage.

Servicing Fee/
Trustee Fee: The Trust is subject to certain fees,
including a Servicing Fee of approximately
0.51% per annum payable monthly at
one-twelfth of the annual rate. The Trustee
Fee will be paid separately by the Master
Servicer and will not be deducted from cash
flows allocable to the Trust.
Denominations: $25,000 minimum and integral multiples of $1
in excess thereof, except for the Class A-IO
Certificates, which will be issued in
minimum denominations of a 20% percentage
interest and integral multiples of 0.01% in
excess thereof. The Class A-IO Certificates
will be divided into three components (each,
a "Component"). The Class A-IO Components
are not separately transferable as distinct
securities.
Tax Status: For federal income tax purposes, two or more
real estate mortgage investment conduit
(each, a "REMIC") elections will be made and
each REMIC will qualify as a REMIC under the
Internal Revenue Code.
ERISA Eligibility: The Class A-1, Class A-2 and Class A-IO
Certificates only will be ERISA eligible.
Prospective pension plan investors should
consult their own counsel with respect to an
investment in the Offered Certificates. The
Class M-1, Class M-2 and Class B
Certificates will not be ERISA eligible.
SMMEA Treatment: At such time as the Pre-funding Account has
been reduced to zero, the Senior
Certificates and the Class M-1 Certificates
will constitute "mortgage related
securities" for purposes of SMMEA. The Class
M-2 and Class B Certificates will not
constitute "mortgage related securities" for
purposes of SMMEA.
Prospectus: The Offered Certificates are being offered
pursuant to a prospectus which includes a
prospectus supplement (together, the
"Prospectus"). Complete information with
respect to the Offered Certificates and the
Mortgage Loans is contained in the
Prospectus. The material presented herein is
qualified in its entirety by the information
appearing in the Prospectus. To the extent
that the foregoing is inconsistent with the
Prospectus, the Prospectus shall govern in
all respects. Sales of the Offered
Certificates may not be consummated unless
the purchaser has received the Prospectus.
