      The asset-backed securities referred to in these materials, and the asset
pools backing them, are subject to modification or revision (including the
possibility that one or more classes of securities may be split, combined or
eliminated at any time prior to issuance or availability of a final prospectus)
and are offered on a "when, as and if issued" basis. You understand that, when
you are considering the purchase of these securities, a contract of sale will
come into being no sooner than the date on which the relevant class has been
priced and we have confirmed the allocation of securities to be made to you; any
"indications of interest" expressed by you, and any "soft circles" generated by
us, will not create binding contractual obligations for you or us.

      Because the asset-backed securities are being offered on a "when, as and
if issued" basis, any contract of sale will terminate, by its terms, without any
further obligation or liability between us, if the securities themselves, or the
particular class to which the contract relates, are not issued. In addition,
since the asset-backed securities and the asset pools backing them are subject
to modification or revision (including the possibility that one or more classes
of securities may be split, combined or eliminated at any time prior to issuance
or availability of a final prospectus), any such contract also is conditioned
upon the understanding that no material change will occur with respect to the
relevant class of securities prior to the closing date. If a material change
does occur with respect to such class, our contract will terminate, by its
terms, without any further obligation or liability between us (the "Automatic
Termination"). If an Automatic Termination occurs, we will provide you with
revised offering materials reflecting the material change and give you an
opportunity to purchase such class. To indicate your interest in purchasing the
class, you must communicate to us your desire to do so within such timeframe as
may be designated in connection with your receipt of the revised offering
materials.

                                            pass-through trusts that consist of

                                            acquisition and holding of the

                                            to which it applies provided that

                                            other than those within the control
                                            of the investors are met. In

                                            there is no single mortgagor that is
                                            the obligor on 5% of the initial
                                            balance of the Mortgage Pool.

                                            If there are Mortgage Loans with

                                            loan group within the Mortgage Pool,
                                            the Exemption will not cover the
                                            acquisition and holding of the
                                            related offered Super Senior Support

                                            Prospective Plan investors should
                                            consult with their legal advisors
                                            concerning the impact of ERISA, the
                                            Code and Similar Law, the
                                            applicability of PTE 83-1 and the
                                            Exemption, and the potential
                                            consequences in their specific
                                            circumstances, prior to making an
                                            investment in the Offered
                                            Certificates. Moreover, each Plan
                                            fiduciary should determine whether
                                            under the governing plan instruments
                                            and the applicable fiduciary
                                            standards of investment prudence and
                                            diversification, an investment in
                                            the Offered Certificates is
                                            appropriate for the Plan, taking
                                            into account the overall investment
                                            policy of the Plan and the
                                            composition of the Plan's investment
                                            portfolio.

                          Preliminary Summary of Terms
                          ----------------------------

Tax Structure.............................  For federal income tax purposes, the
                                            Trust will be treated as one or more
                                            "real estate mortgage investment
                                            conduits" (each, a "REMIC").

                                            o     The Senior Certificates (other
                                                  than the residual certificate
                                                  and any exchangeable
                                                  certificates) and the
                                                  Subordinate Certificates will
                                                  constitute "regular interests"
                                                  in a REMIC and will be treated
                                                  as newly-originated debt
                                                  instruments for most federal
                                                  income tax purposes.

                                            o     Generally, for a class of
                                                  component certificates, each
                                                  component, rather than the
                                                  class itself, will constitute
                                                  a regular interest in a REMIC.

                                            o     The residual certificate will
                                                  represent the sole "residual
                                                  interest" in each REMIC.

                                            You must report income received on
                                            your Offered Certificates as it
                                            accrues from Distribution Date to
                                            Distribution Date, even if it is
                                            before such income is distributed in
                                            cash to you.

                                            Certain classes of Offered
                                            Certificates may be issued with
                                            "original issue discount." If your
                                            class of Offered Certificates is
                                            issued with original issue discount,
                                            you must report original issue
                                            discount income over the life of
                                            your Certificate, often well before
                                            such income is distributed in cash
                                            to you.

                                            If you hold an Offered Certificate
                                            that has the benefit of a yield
                                            maintenance agreement and is
                                            entitled to certain payments from a
                                            reserve account, you will be treated
                                            as owning two assets, a REMIC
                                            regular interest and the right to
                                            receive payments from the reserve
                                            fund and will be required to account
                                            separately for each of these assets
                                            for federal income tax purposes.

                                            If you hold an Offered Certificate
                                            that is an exchangeable certificate,
                                            you should be aware that the
                                            arrangement under which any
                                            exchangeable certificates are
                                            created will be classified as a
                                            grantor trust and each class of
                                            exchangeable certificates so created
                                            will represent beneficial ownership
                                            of an interest in each related
                                            exchangeable REMIC certificate.

Optional Termination Date.................  On any Distribution Date on which
                                            the aggregate Stated Principal
                                            Balance of the Mortgage Loans is
                                            less than 10% of the initial
                                            aggregate unpaid principal balance
                                            of the Mortgage Loans as of the

                                            of the servicing fee rate (which is
                                            0.25%) and the trustee fee rate

                                            Rate as of the Cut-off Date less
                                            than a certain rate (each such
                                            Mortgage Loan, a "Discount Mortgage
                                            Loan") will be equal to the Net

                                            Pool, this rate may be the same for
                                            each loan group or may differ for
                                            one or more loan groups. The Non-PO
                                            Percentage with respect to any

                                            for any Discount Mortgage Loan will
                                            be equal to 100% minus the Non-PO
                                            Percentage for such Mortgage Loan.

                           Preliminary Credit Support
                           --------------------------

Subordinate Certificates provide credit support for Senior Certificates. If the
Senior Certificates are divided into multiple groups, the Subordinate
Certificates may or may not consist of multiple groups. If there are multiple
groups of Subordinate Certificates, each group will support one or more groups
of Senior Certificates. Additional credit enhancement is provided by the
allocation of the applicable Non-PO Percentages of all principal prepayments on
the applicable Mortgage Loans to the related Senior Non-PO Certificates, subject
to certain exceptions, for the first five years and the disproportionately
greater allocation of prepayments to such Senior Non-PO Certificates over the
following four years. The disproportionate allocation of the applicable Non-PO
Percentages of prepayments on the Mortgage Loans will accelerate the
amortization of those Senior Non-PO Certificates relative to the amortization of
the related Subordinate Certificates. As a result, the credit support percentage
for the Senior Certificates should be maintained and may be increased during the
first nine years. If there is one group of Subordinate Certificates, the initial
credit support percentage for the Senior Certificates (calculated by dividing
the initial Class Balance of the Subordinate Certificates by the aggregate Pool
Principal Balance) is expected to be 4.60% (+/- 50 basis points).

                            Priority of Distributions
                            -------------------------

Distributions will be made on each Distribution Date from the Pool Distribution
Amount (if the Mortgage Pool is not divided into loan groups) or Amounts (if
there are multiple loan groups, in which case the Senior Certificates and any
components of a group will be paid from the related Pool Distribution Amount) in
the following order of priority:

         --------------------------------------------------------------
           First, to the classes of Senior Certificates and component
           (if any) entitled to payments of interest, to pay interest;
         --------------------------------------------------------------

                                        v
         --------------------------------------------------------------
           Second, pro rata, to the Senior Non-PO Certificates and any
           ratio strip component or ratio strip certificates entitled
                   to payments of principal, to pay principal;
         --------------------------------------------------------------
                                        |
                                        |
                                        |
                                        v
         --------------------------------------------------------------
               Third, to any ratio strip component or ratio strip
            certificates, to pay any Class PO Deferred Amounts, from
              amounts otherwise payable as principal to the related
                            Subordinate Certificates;
         --------------------------------------------------------------
                                        |
                                        |

         --------------------------------------------------------------
            Fourth, subject to any cross-collateralization payments,
          sequentially, to each class of Subordinate Certificates from
             the related Pool Distribution Amount or Amounts to pay
            interest and principal in the order of payment priority,
                      until each Class Balance is zero; and
         --------------------------------------------------------------
                                        |
                                        |
                                        |
                                        v
         --------------------------------------------------------------
           Fifth, to the residual certificate, any remaining amounts.

                                            more likely to suffer losses as a
                                            result of losses or delinquencies on
                                            the related Mortgage Loans than are
                                            Senior certificateholders.

                                                  Certificates and each class of
                                                  related Subordinate
                                                  Certificates higher in order
                                                  of payment priority.

                                            o     Losses that are realized on
                                                  the Mortgage Loans will be
                                                  allocated first to the class
                                                  of related Subordinate

                                                  of payment priority, then to
                                                  the class of related

                                                  until the outstanding Class

                                                  been reduced to zero.

                                            Any Super Senior Support
                                            certificateholders should consider
                                            the risk that after the related
                                            Subordinate Certificates are no
                                            longer outstanding, the principal
                                            portion of losses realized on the
                                            applicable Mortgage Loans that are
                                            allocated to a class of Super Senior
                                            Certificates will be borne by the
                                            related class of Super Senior
                                            Support Certificates, rather than
                                            such class of Super Senior
                                            Certificates.

The Rate of Principal
Payments on the Mortgage
Loans Will Affect the Yield
on the Offered Certificates...............  Because principal payments on the
                                            Mortgage Loans will be distributed
                                            currently on the related Senior
                                            Certificates and the related
                                            Subordinate Certificates, the rate
                                            of distributions of principal and
                                            the yield to maturity on your
                                            Certificates will be directly
                                            related to (i) the rate and timing
                                            of payments of principal on the
                                            applicable Mortgage Loans and (ii)
                                            the amount and timing of defaults by

                                            The timing of changes in the rate of
                                            prepayments may significantly affect
                                            the actual yield to you, even if the
                                            average rate of principal
                                            prepayments is consistent with your
                                            expectations. In general, the
                                            earlier the payment of principal of
                                            the related Mortgage Loans, the
                                            greater the effect on your yield to
                                            maturity. As a result, the effect on
                                            your yield of principal prepayments
                                            occurring at a rate higher (or
                                            lower) than the rate you anticipate
                                            during the period immediately
                                            following the issuance of the
                                            certificates will not be offset by a
                                            subsequent like reduction (or
                                            increase) in the rate of principal
                                            prepayments.

                                            will require the applicable

Delinquencies and Losses
on the Mortgage Loans
Will Adversely
Affect Your Yield.........................  Delinquencies on the mortgage loans
                                            which are not advanced by or on
                                            behalf of the Servicer (because the
                                            Servicer has determined that these
                                            amounts, if advanced, would be
                                            nonrecoverable), will adversely
                                            affect the yield on the related
                                            Senior Certificates and the related
                                            Subordinate Certificates. The
                                            Servicer will determine that a
                                            proposed advance is nonrecoverable
                                            when, in the good faith exercise of
                                            its servicing judgment, it believes
                                            the proposed advance would not be
                                            ultimately recoverable from the
                                            related mortgagor, related
                                            liquidation proceeds, or other
                                            recoveries in respect of the
                                            Mortgage Loan. Because of the
                                            priority of distributions,
                                            shortfalls resulting from
                                            delinquencies that are not covered
                                            by advances will be borne first by
                                            the related Subordinate Certificates
                                            (in reverse order of payment
                                            priority), and then by the related
                                            Senior Certificates.

                                            Net interest shortfalls will
                                            adversely affect the yields on the
                                            Offered Certificates. In addition,
                                            losses generally will be borne by
                                            the related Subordinate
                                            Certificates. As a result, the
                                            yields on the Offered Certificates
                                            will depend on the rate and timing
                                            of realized losses on the related
                                            Mortgage Loans.

There Are Risks Relating to
Exchangeable REMIC Certificates
and Exchangeable Certificates.............  If you are purchasing any
                                            Exchangeable REMIC Certificates or
                                            Exchangeable Certificates, you
                                            should consider that the
                                            characteristics of any Exchangeable
                                            Certificates will reflect, in the
                                            aggregate, generally the
                                            characteristics of the related
                                            Exchangeable REMIC Certificates.
                                            Investors are encouraged to also
                                            consider a number of factors that
                                            will limit a certificateholder's
                                            ability to exchange Exchangeable
                                            REMIC Certificates for Exchangeable
                                            Certificates and vice versa:

                                            o     At the time of the proposed
                                                  exchange, a certificateholder
                                                  must own Certificates of the
                                                  related Class or Classes in
                                                  the proportions necessary to
                                                  make the desired exchange.

                                            o     A certificateholder that does
                                                  not own the Certificates may
                                                  be unable to obtain the
                                                  necessary Exchangeable REMIC

                                                  Certificates because the
                                                  holders of the needed
                                                  Certificates may be unwilling
                                                  or unable to sell them or
                                                  because the necessary

                                                  into other financial
                                                  structures.

                                            o     Principal distributions will
                                                  decrease the amounts available

Credit Scores May Not
Accurately Predict the
Likelihood of Default.....................  The Sponsor generally uses Credit
                                            Scores as part of its underwriting
                                            process. The attached collateral
                                            summary shows credit scores for the
                                            mortgagors obtained at the time of
                                            origination of their mortgage loans.
                                            A credit score purports only to be a
                                            measurement of the relative degree
                                            of risk a borrower represents to a
                                            lender, i.e., that a borrower with a
                                            higher score is statistically
                                            expected to be less likely to
                                            default in payment than a borrower
                                            with a lower score. In addition, it
                                            should be noted that credit scores
                                            were developed to indicate a level
                                            of default probability over a
                                            two-year period, which does not
                                            correspond to the life of most
                                            mortgage loans. Furthermore, credit
                                            scores were not developed
                                            specifically for use in connection
                                            with mortgage loans, but for
                                            consumer loans in general.
                                            Therefore, credit scores do not
                                            address particular mortgage loan
                                            characteristics that influence the
                                            probability of repayment by the
                                            borrower. Neither the Depositor nor
                                            the Sponsor makes any
                                            representations any mortgage loan or
                                            that a particular credit score
                                            should be relied upon as a basis for
                                            an expectation that a borrower will
                                            repay its mortgage loan according to
                                            its terms.

Geographic Concentration
May Increase Risk of Loss Due to
Adverse Economic Conditions
or Natural Disasters......................  At various times, certain geographic
                                            regions will experience weaker
                                            economic conditions and housing
                                            markets and, consequently, will
                                            experience higher rates of
                                            delinquency and loss on mortgage
                                            loans generally. In addition,
                                            certain states have experienced
                                            natural disasters, including
                                            earthquakes, fires, floods and
                                            hurricanes, which may adversely
                                            affect property values. Although
                                            mortgaged properties located in
                                            certain identified flood zones will
                                            be required to be covered, to the
                                            maximum extent available, by flood
                                            insurance, no mortgaged properties
                                            will otherwise be required to be
                                            insured against earthquake damage or
                                            any other loss not covered by
                                            standard hazard insurance policies.
                                            Any concentration of mortgaged
                                            properties in a state or region may
                                            present unique risk considerations.
                                            See the tables entitled "Geographic

                                            Any deterioration in housing prices
                                            in a state or region due to adverse
                                            economic conditions, natural
                                            disaster or other factors, and any
                                            deterioration of economic conditions
                                            in a state or region that adversely
                                            affects the ability of borrowers to
                                            make payments on the mortgage loans,
                                            may result in losses on the Mortgage
                                            Loans. Any losses may adversely
                                            affect the yield to maturity of the
                                            related Offered Certificates.

                                  ------------

Residential Real Estate
Values May Fluctuate and Adversely
Affect Your Investment....................  There can be no assurance that
                                            values of the mortgaged properties
                                            have remained or will remain at
                                            their levels on the dates of
                                            origination of the related Mortgage
                                            Loans. The value of any mortgaged
                                            property generally will change over
                                            time from its value on the appraisal
                                            or sales date. If residential real
                                            estate values generally or in a
                                            particular geographic area decline,
                                            the loan-to-value ratios shown in
                                            the table in the accompanying
                                            collateral annex might not be a
                                            reliable indicator of the rates of
                                            delinquencies, foreclosures and
                                            losses that could occur on the
                                            Mortgage Loans. If the residential
                                            real estate market should experience
                                            an overall decline in property
                                            values large enough to cause the
                                            outstanding balances of the Mortgage
                                            Loans and any secondary financing on
                                            the related mortgaged properties to
                                            equal or exceed the value of the
                                            mortgaged properties, delinquencies,
                                            foreclosures and losses could be
                                            higher than those now generally
                                            experienced in the mortgage lending
                                            industry or in the Sponsor's prior
                                            securitizations involving the
                                            Depositor.

                                            In addition, adverse economic
                                            conditions and other factors (which
                                            may or may not affect real property
                                            values) may affect the mortgagors'
                                            timely payment of scheduled payments
                                            of principal and interest on the
                                            Mortgage Loans and, accordingly, the
                                            actual rates of delinquencies,
                                            foreclosures and losses with respect
                                            to the mortgage pool. These other
                                            factors could include excessive
                                            building resulting in an oversupply
                                            of housing in a particular area or a
                                            decrease in employment reducing the
                                            demand for housing in an area. To
                                            the extent that credit enhancements
                                            do not cover such losses, your yield
                                            may be adversely impacted.

United States Military
Operations May Increase
Risk of Relief Act Shortfalls.............  As a result of military operations
                                            in Afghanistan and Iraq, the United
                                            States has placed a substantial
                                            number of armed forces reservists
                                            and members of the National Guard on
                                            active duty status. It is possible
                                            that the number of reservists and
                                            members of the National Guard placed
                                            on active duty status may remain at
                                            high levels for an extended time. To
                                            the extent that a member of the
                                            military, or a member of the armed
                                            forces reserves or National Guard
                                            who is called to active duty, is a
                                            mortgagor of a mortgage loan in the
                                            trust, the interest rate limitation
                                            of the Servicemembers Civil Relief
                                            Act, and any comparable state law,
                                            will apply. This may result in
                                            interest shortfalls on the Mortgage
                                            Loans in the trust, which will be
                                            borne by all classes of interest
                                            bearing Certificates and components.
                                            Neither the Sponsor nor the
                                            Depositor has taken any action to
                                            determine whether any of the
                                            Mortgage Loans would be affected by
                                            these interest rate limitations.

                                  ------------

The Certificates May Not
Receive Amounts Expected
from any Yield
Maintenance Agreements....................  The yield maintenance agreement
                                            payment for any Distribution Date
                                            will be based on the lesser of (x)
                                            the Class Balance(s) of the related
                                            Class or Classes or (y) the related
                                            notional amount, which will decrease
                                            for each Distribution Date during
                                            the life of the applicable yield
                                            maintenance agreement. The notional
                                            amounts are generally derived by
                                            using an assumed prepayment rate for
                                            the applicable mortgage loans. The
                                            actual rate of prepayment on the
                                            applicable mortgage loans is likely
                                            to differ from the rate assumed. If
                                            prepayments on these mortgage loans
                                            occur at a rate slower than the rate
                                            used in determining the notional
                                            amounts, the Class Balance(s) of the
                                            related Class or Classes will be
                                            greater than the related notional
                                            amount for a Distribution Date and a
                                            holder of the related Certificates
                                            will receive less than if the
                                            counterparty were required to make
                                            payments based on the Class
                                            Balance(s) of the related Class or
                                            Classes.

There is a Risk that Interest
Payments on the Mortgage Loans
May Be Insufficient to Pay Interest
on Your Certificates......................  When a Mortgage Loan is prepaid in
                                            full, the mortgagor is charged
                                            interest only up to the date on
                                            which payment is made, rather than
                                            for an entire month. When a
                                            mortgagor makes a partial principal
                                            prepayment on a Mortgage Loan, the
                                            mortgagor is not charged interest on
                                            the prepayment for the month in
                                            which the principal prepayment was
                                            received. This may result in a
                                            shortfall in interest collections
                                            available for payment on the next
                                            Distribution Date. The Servicer is
                                            required to cover a portion of the
                                            shortfall in interest collections
                                            that are attributable to prepayments
                                            in full and partial prepayments on
                                            the Mortgage Loans, but in each case
                                            only up to the amount of
                                            Compensating Interest related to
                                            such Mortgage Loans for such
                                            Distribution Date. To the extent
                                            these shortfalls are not covered by
                                            the amount of related Compensating
                                            Interest, they will be allocated pro
                                            rata to the related classes of
                                            interest-bearing Certificates and
                                            any related components.

Certificates May Not Be
Appropriate for Individual
Investors.................................  If you are an individual investor
                                            who does not have sufficient
                                            resources or expertise to evaluate
                                            the particular characteristics of a
                                            class of Offered Certificates, the
                                            Offered Certificates may not be an
                                            appropriate investment for you. This
                                            may be the case because, among other
                                            things:

                                            o     if you purchase your
                                                  Certificates at a price other
                                                  than par, your yield to
                                                  maturity will be sensitive to
                                                  the uncertain rate and timing
                                                  of principal prepayments on
                                                  the applicable Mortgage Loans;

                                            their affiliates. Consequently, if

                                            insufficient or otherwise

Limited Liquidity.........................  The Underwriter intends to make a
                                            market for purchase and sale of the
                                            Offered Certificates after their
                                            initial issuance, but the
                                            Underwriter has no obligation to do
                                            so. There is no assurance that such

                                            if it does develop, that it will
                                            provide you with liquidity of

                                  ------------

                                            or you may not be able to sell your
                                            Certificates at a high enough price
                                            to produce your desired return on
                                            investment.

                                            The secondary market for
                                            mortgage-backed securities has
                                            experienced periods of illiquidity
                                            and can be expected to do so in the
                                            future. Illiquidity means that there
                                            may not be any purchasers for your
                                            class of Certificates. Although any
                                            class of Certificates may experience
                                            illiquidity, it is more likely that
                                            classes of Certificates that are
                                            more sensitive to prepayment, credit
                                            or interest rate risk (such as the
                                            Interest Only, Super Senior Support,
                                            Companion, Inverse Floating Rate,
                                            Principal Only, or Subordinated
                                            Certificates) will experience
                                            illiquidity.

Alternative Underwriting
Standards May Increase Risk of Loss.......  Certain of the Mortgage Loans may
                                            have been originated using the
                                            Sponsor's "Alternative A"
                                            underwriting guidelines. See "The
                                            Mortgage Loan Programs--Mortgage
                                            Loan Underwriting--Bank of America
                                            Alternative Underwriting Standards"
                                            in the base prospectus. These
                                            underwriting guidelines are
                                            different from and, in certain
                                            respects, less stringent than the
                                            general underwriting guidelines
                                            employed by the sponsor. For
                                            example, certain of the mortgage
                                            loans may have been originated with
                                            less than standard documentation or
                                            with higher maximum loan-to-value
                                            ratios. Accordingly, the mortgage
                                            loans may experience rates of
                                            delinquencies, defaults,
                                            foreclosure, bankruptcy and loss
                                            that are higher than those
                                            experienced by mortgage loans
                                            underwritten using the Sponsor's
                                            general underwriting standards.

The Rate of Default on
Mortgage Loans that Are
Secured by Investor
Properties May be Higher than on
Other Mortgage Loans......................  Certain of the Mortgage Loans may be
                                            secured by investor properties. An
                                            investor property is a property
                                            which, at the time of origination,
                                            the mortgagor represented would not
                                            be used as the mortgagor's primary
                                            residence or second home. Because
                                            the mortgagor is not living on the
                                            property, the mortgagor may be more
                                            likely to default on the mortgage
                                            loan than on a comparable mortgage
                                            loan secured by a primary residence,
                                            or to a lesser extent, a second
                                            home. In addition, income expected
                                            to be generated from an investor
                                            property may have been considered
                                            for underwriting purposes in
                                            addition to the income of the
                                            mortgagor from other sources. Should
                                            this income not materialize, it is
                                            possible the mortgagor would not
                                            have sufficient resources to make
                                            payments on the mortgage loan.

There Are Risks Relating
to Mortgaged Properties Subject to
Second Lien Mortgage Loans................  At the time of origination of
                                            certain of the Mortgage Loans, a
                                            lender other than the Sponsor may
                                            have originated a second lien
                                            mortgage loan. Mortgage Loans that
                                            have second lien mortgage loans

                                  ------------

                                            encumbering the same mortgaged
                                            property may have higher rates of
                                            delinquency and foreclosure relative
                                            to mortgage loans that do not have
                                            second lien mortgage loans behind
                                            them. This may be due to changes in
                                            the mortgagor's debt-to-income
                                            profile, the fact that mortgagors
                                            may then have less equity in the
                                            mortgaged property or other factors.
                                            You should also note that any
                                            mortgagor could obtain a second lien
                                            mortgage loan at any time subsequent
                                            to the date of origination of their
                                            first lien mortgage loan from any
                                            lender.

Subordinate Certificates
May Provide Subordination for All
Groups....................................  The Subordinate Certificates may
                                            provide credit support for more than
                                            one Groups of Senior Certificates
                                            and thus the outstanding Class
                                            Balances of such Subordinate
                                            Certificates could be reduced to
                                            zero as a result of a
                                            disproportionate amount of principal
                                            losses on the Mortgage Loans in one
                                            Loan Group. Therefore, these losses
                                            on the Mortgage Loans in one Loan
                                            Group will reduce the subordination
                                            provided by the Subordinate
                                            Certificates to the other Groups of
                                            Senior Certificates and increase the
                                            likelihood that losses may be
                                            allocated to the other Groups of

                                            principal otherwise payable to these

High Rates of LIBOR or Another
Index May Result in a Lower or
Negative Yield on any Inverse
Floating Rate Interest Only
Certificates..............................  If you are purchasing any inverse
                                            floating rate interest only
                                            certificates, in addition to the
                                            risk that a rapid rate of
                                            prepayments on the related Mortgage
                                            Loans may result in a lower actual
                                            yield than you expected or a
                                            negative yield, you should also
                                            consider the risk that high rates of
                                            LIBOR or high rates of another
                                            applicable index for your
                                            certificates may result in the
                                            failure to recover your initial
                                            investment.

                      Categories of Classes of Certificates

      The Certificates of any series may be comprised of one or more classes.
The classes, in general, fall into different categories. The chart in the base
prospectus under the heading "Description of the Certificates--Categories of
Classes of Certificates" identifies and generally defines certain of the more
typical categories. The prospectus supplement for a series of Certificates may
identify the classes which comprise that series by reference to those categories
or another category specified in the prospectus supplement.

      The asset-backed securities referred to in these materials, and the asset
pools backing them, are subject to modification or revision (including the
possibility that one or more classes of securities may be split, combined or
eliminated at any time prior to issuance or availability of a final prospectus)
and are offered on a "when, as and if issued" basis. You understand that, when
you are considering the purchase of these securities, a contract of sale will
come into being no sooner than the date on which the relevant class has been
priced and we have confirmed the allocation of securities to be made to you; any
"indications of interest" expressed by you, and any "soft circles" generated by
us, will not create binding contractual obligations for you or us.

      Because the asset-backed securities are being offered on a "when, as and
if issued" basis, any contract of sale will terminate, by its terms, without any
further obligation or liability between us, if the securities themselves, or the
particular class to which the contract relates, are not issued. In addition,
since the asset-backed securities and the asset pools backing them are subject
to modification or revision (including the possibility that one or more classes
of securities may be split, combined or eliminated at any time prior to issuance
or availability of a final prospectus), any such contract also is conditioned
upon the understanding that no material change will occur with respect to the
relevant class of securities prior to the closing date. If a material change
does occur with respect to such class, our contract will terminate, by its
terms, without any further obligation or liability between us (the "Automatic
Termination"). If an Automatic Termination occurs, we will provide you with
revised offering materials reflecting the material change and give you an
opportunity to purchase such class. To indicate your interest in purchasing the
class, you must communicate to us your desire to do so within such timeframe as
may be designated in connection with your receipt of the revised offering
materials.
