      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. Because the
asset-backed securities are subject to modification or revision, 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.

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

                                    If there are Mortgage Loans with
                                    loan-to-value ratios in excess of 100% in
                                    the Mortgage Pool or in a loan group within
                                    the Mortgage Pool, the Exemption will not
                                    cover the acquisition and holding of the
                                    related offered Super Senior Support or
                                    Subordinate Certificates.

                                    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 Offered Certificates (other than
                                          the residual certificate) 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.

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

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 Cut-off
                                    Date, the Depositor may, at its option,
                                    subject to certain conditions, purchase the
                                    Mortgage Loans, which would effect an early
                                    retirement of the Certificates.

                                    If the Mortgage Loans are divided into
                                    multiple loan groups with more than one set
                                    of Subordinate Certificates, the Depositor
                                    may, at its option, subject to certain
                                    conditions, purchase the Mortgage Loans in
                                    one or some of the loan groups, which would
                                    effect an early retirement of only the
                                    related Certificates.

The Pooling Agreement:              The Certificates will be issued pursuant to
                                    a Pooling and Servicing Agreement (the
                                    "Pooling Agreement") to be dated the Closing
                                    Date, among the Depositor, the Servicer and
                                    the Trustee.

The Mortgage Pool:                  The "Mortgage Pool" will consist of fixed
                                    rate, conventional, fully-amortizing
                                    mortgage loans (the "Mortgage Loans")
                                    secured by first liens on one- to
                                    four-family properties. All of the Mortgage
                                    Loans were originated or acquired by Bank of
                                    America, National Association, which is an
                                    affiliate of the Depositor and Banc of
                                    America Securities LLC. In addition, certain
                                    of the Mortgage Loans were originated using
                                    underwriting standards that are different
                                    from, and in certain respects, less
                                    stringent than the general underwriting
                                    standards of Bank of America, National
                                    Association. See "Underwriting Guidelines of
                                    Bank of America" below.

                                    The Mortgage Pool may be divided into
                                    multiple loan groups.

The Mortgage Loans:                 The Mortgage Loans consist of fixed rate,
                                    conventional, fully amortizing mortgage
                                    loans secured by first liens on one- to
                                    four-family residential properties.
                                    Substantially all of the Mortgage Loans will
                                    have original terms to stated maturity of
                                    approximately 20 to 30 years. Borrowers are
                                    permitted to prepay their Mortgage Loans, in
                                    whole or in part, at any time. If indicated
                                    in the Collateral Summary at the end of this
                                    Free Writing Prospectus, certain of the
                                    Mortgage Loans may be subject to prepayment
                                    premiums. Accordingly, the actual date on
                                    which any Mortgage Loan is paid in full may
                                    be earlier than the stated maturity date due
                                    to unscheduled payments of principal. See
                                    the Collateral Summary at the end of this

                                    obligated to pay to the Trustee, for deposit

                                    equal to the product of (a) the amount by
                                    which (i) the lesser of LIBOR and a
                                    designated maximum percentage exceeds (ii)

                                    Pursuant to the Pooling Agreement, the
                                    Trustee will establish a separate trust
                                    account (the "Reserve Fund") for deposit of
                                    any payments that it may receive under a

                                    used to make certain payments on a specified

                                    any month will be reduced (but not below
                                    zero) by an amount equal to the lesser of
                                    (i) the aggregate of the Prepayment Interest
                                    Shortfalls for such Distribution Date and
                                    (ii) one-twelfth of 0.25% of the aggregate
                                    Stated Principal Balance of the Mortgage
                                    Loans as of the due date in the month
                                    preceding the month of such Distribution
                                    Date (such amount, the "Compensating
                                    Interest").

                                    If a group of Subordinate Certificates
                                    supports multiple groups of Senior
                                    Certificates, Compensating Interest will be
                                    determined on an aggregate basis with
                                    respect to all related loan groups. If a
                                    group of Subordinate Certificates supports
                                    one group of Senior Certificates,
                                    Compensating Interest will be determined for
                                    the related loan group.

 Advances:                          Subject to the certain limitations, the
                                    Servicer will be required pursuant to the

                                    advance, an "Advance") prior to each
                                    Distribution Date an amount equal to the
                                    aggregate of payments of principal and
                                    interest (net of the Servicing Fee) which
                                    were due on the related due date on the

                                    the related Determination Date. Advances
                                    made by the Servicer will be made from its
                                    own funds or funds available for future
                                    distribution. The obligation to make an

Shifting Interest Structure:        Additional credit enhancement is provided by
                                    the allocation of the applicable Non-PO
                                    Percentages of principal prepayments on the
                                    Mortgage Loans in the Mortgage Pool or a
                                    loan group in the Mortgage Pool to the
                                    related Senior Certificates for the first
                                    five years and the disproportionately
                                    greater allocation of prepayments to such
                                    Senior Certificates over the following four
                                    years. The disproportionate allocation of
                                    the applicable Non-PO Percentages of
                                    prepayments on the Mortgage Loans in the
                                    Mortgage Pool or a loan group in the
                                    Mortgage Pool will accelerate the
                                    amortization of those Senior Certificates
                                    relative to the amortization of the
                                    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.

Allocation of Losses:               On each Distribution Date, the applicable PO
                                    Percentage of any Realized Loss on a
                                    Discount Mortgage Loan will be allocated to
                                    the ratio strip certificate or ratio strip
                                    component of the related group until its

                                    effected on each Distribution Date by
                                    reducing the Class Balance of the ratio
                                    strip certificate or principal balance of
                                    the ratio strip component of the related
                                    group if and to the extent that such balance
                                    (after taking into account the amount of all
                                    distributions to be made on such

                                    component of the related group will be paid
                                    on such ratio strip certificate or ratio
                                    strip component of the related group prior

                                    Class PO Deferred Amounts will be made from
                                    the principal payable to the related

                                    certificate or ratio strip component of the
                                    related group will not further reduce the
                                    principal balance of such ratio strip
                                    certificate or ratio strip component of the
                                    related group. The Class PO Deferred Amounts
                                    will not bear interest. The Class Balance of
                                    the class of related Subordinate
                                    Certificates then outstanding with the

                                    reduced by the amount of any payments in
                                    respect of Class PO Deferred Amounts for the
                                    ratio strip certificate or ratio strip
                                    component of the related group. Any excess
                                    of these Class PO Deferred Amounts over the
                                    Class Balance of that class will be
                                    allocated to the next most subordinate class
                                    of related Subordinate Certificates to

                                    order of their numerical class designations

                                    been reduced to zero, and then to the Senior

                           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 Certificates, subject to
certain exceptions, for the first five years and the disproportionately greater
allocation of prepayments to such Senior 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 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 3.95% (+/- 50 basis points). If there are
two groups of Subordinate Certificates, the initial credit support percentage
for the Senior Certificates related to the 20 to 30 year Mortgage Loans
(calculated by dividing the initial Class Balance of the related Subordinate
Certificates by the related Pool Principal Balance) is expected to be 4.25% (+/-
50 basis points) and the initial credit support percentage for the Senior
Certificates related to the 10 to 15 year Mortgage Loans (calculated by dividing
the initial Class Balance of the related Subordinate Certificates by the related
Pool Principal Balance) is expected to be 2.60% (+/- 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;

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

The Sponsor and Servicer:           Bank of America, National Association ("Bank
                                    of America") will serve as the sponsor (the
                                    "Sponsor") of the Certificates. Bank of
                                    America is an indirect wholly-owned
                                    subsidiary of Bank of America Corporation.
                                    Bank of America is engaged in a general
                                    consumer banking, commercial banking, and
                                    trust business, offering a wide range of
                                    commercial, corporate, international,
                                    financial market, retail and fiduciary
                                    banking services. Bank of America is a
                                    national banking association chartered by
                                    the Office of the Comptroller of the
                                    Currency (the "OCC") and is subject to the
                                    regulation, supervision and examination of
                                    the OCC.

                                    Bank of America and its affiliates have been
                                    active in the securitization market since
                                    inception. Bank of America has sponsored
                                    publicly offered securitization transactions
                                    since 1977. Bank of America and its
                                    affiliates have been involved with the
                                    origination of auto loans, student loans,
                                    home equity loans, credit card receivables,
                                    manufactured housing contracts, residential
                                    mortgage loans and commercial mortgage
                                    loans, as well as less traditional asset
                                    classes. Bank of America and its affiliates
                                    have also participated in a variety of
                                    collateralized loan obligation transactions,
                                    synthetic securitizations, and asset-backed
                                    commercial paper programs. Bank of America
                                    and its affiliates have served as sponsors,
                                    issuers, dealers, and servicers in a wide
                                    array of securitization transactions.

                                    The Depositor's securitization program
                                    principally is used to fund Bank of
                                    America's consumer real estate business
                                    unit's self-originated portfolio of fully
                                    amortizing mortgage loans secured by first
                                    liens on one- to four-family residential
                                    properties. The Depositor's securitization
                                    program may also include mortgage loans
                                    originated through correspondent
                                    arrangements. While Bank of America
                                    currently does not rely on securitization as
                                    a material funding source, the Depositor's
                                    securitization program is a material funding
                                    source for Bank of America's portfolio of
                                    consumer real estate mortgage loans similar
                                    to the Mortgage Loans.

                                    Bank of America's headquarters and its
                                    executive offices are located at 101 South

                                    The Application and Use of Credit Scoring
                                    -----------------------------------------

Underwriting Guidelines of Bank     Regardless of the channel in which the loan
of America (Continued):             was originated, a mortgage application is
                                    completed containing information that
                                    assists in evaluating the mortgagor's credit
                                    standing, capacity to repay the loan and
                                    adequacy of the mortgaged property as
                                    collateral for the loan. During the
                                    application process, the applicant is
                                    required to authorize Bank of America to
                                    obtain a credit report that summarizes the
                                    applicant's credit history with merchants
                                    and lenders and any record of bankruptcy or
                                    prior foreclosure. This credit information
                                    may be obtained from either a single credit
                                    repository or from up to three credit
                                    repositories. The credit bureau inquiry also
                                    includes a request for the applicant's
                                    Credit Score. "Credit Scores" are
                                    statistical credit scores obtained by many
                                    mortgage lenders in connection with the loan
                                    application to help assess a borrower's
                                    creditworthiness. Credit Scores are
                                    generated by models developed by a third
                                    party and are made available to lenders
                                    through three national credit bureaus,
                                    Experian (FICO), Equifax (Beacon) and
                                    TransUnion (Empirica). The models were
                                    derived by analyzing data on consumers in
                                    order to establish patterns which are
                                    believed to be indicative of the borrower's
                                    probability of default. A Credit Score is
                                    based on a borrower's historical credit
                                    data, including, among other things, payment
                                    history, delinquencies on accounts, levels
                                    of outstanding indebtedness, length of
                                    credit history, types of credit, and
                                    bankruptcy experience. Credit Scores range
                                    from approximately 300 to approximately 850,
                                    with higher scores indicating an individual
                                    with a more favorable credit history
                                    compared to an individual with a lower
                                    score. If the credit bureaus cannot generate
                                    a Credit Score due to insufficient
                                    information about an applicant, Bank of
                                    America will consider proof of an
                                    applicant's alternative credit history, such
                                    as a history of consistent rent and utility
                                    payments.

                                    In addition to a Credit Score, Bank of
                                    America may obtain a Custom Mortgage Score.
                                    In order to generate a Custom Mortgage
                                    Score, the applicant must have at least one
                                    trade line on his or her credit report and
                                    also have a Credit Score. The "Custom
                                    Mortgage Score" was developed on a
                                    population of mortgage loans serviced by
                                    Bank of America and is designed to assess
                                    the likelihood that a mortgage loan will
                                    become 60 days or more delinquent within two
                                    years of application. The Custom Mortgage
                                    Score used by Bank of America will either
                                    have been developed by Bank of America
                                    individually or with the assistance of a
                                    third party. The Custom Mortgage Score
                                    requires a Credit Score and utilizes
                                    information obtained from one of the three
                                    major credit bureaus. The credit bureau used
                                    depends on the geographic location of the
                                    applicant's residence at the time of
                                    application. Bank of America may evaluate a
                                    prospective borrower's creditworthiness with
                                    either (i) a Credit Score, (ii) a Custom
                                    Mortgage Score or (iii) a combination of a
                                    Credit Score and a Custom Mortgage Score.

                                    and documentation requirements for the loan
                                    transaction. The automated underwriting
                                    decision engine may be an engine developed
                                    by an outside company and updated by Bank of
                                    America risk management personnel to
                                    facilitate automated decisions on Bank of
                                    America loan transactions. Alternatively, it
                                    may be an external decision engine such as
                                    Fannie Mae's Desktop Underwriter(R) or
                                    Freddie Mac's Loan Prospector(R) decision
                                    engines. If the loan is not automatically
                                    approved or declined by the automated
                                    underwriting decision engine, it is directed
                                    to an underwriter who evaluates the
                                    application against a set of specific
                                    criteria. The underwriter may be an employee
                                    of the lender or may be an individual
                                    performing underwriting on a contract basis
                                    through a third party firm such as a
                                    mortgage insurance company.

Underwriting Guidelines of Bank     Either the automated underwriting decision
of America (Continued):             engine or the underwriter evaluates the
                                    application information to the guidelines
                                    for the product type under which the
                                    applicant has applied. As part of the
                                    underwriting evaluation, the Loan-to-Value
                                    Ratio is calculated. The "Loan to Value
                                    Ratio" is the percentage equal to (i) the
                                    principal balance of the mortgage loan at
                                    origination divided by (ii) the lesser of
                                    (a) the appraised value of the related
                                    mortgaged property determined in an
                                    appraisal obtained at origination of the
                                    mortgage loan or an automated valuation
                                    model or tax assessed value (if permitted by
                                    the applicable product type) and (b) except
                                    for mortgage loans made for refinancing
                                    purposes, the sales price for the mortgaged
                                    property. In addition to evaluating the
                                    Loan-to-Value Ratio, the automated
                                    underwriting decision engine or human
                                    underwriter will also evaluate the
                                    applicant's credit history and/or Credit
                                    Score and/or Custom Mortgage Score, the
                                    amount of the applicant's debts (including
                                    proposed housing payment and related
                                    expenses such as property taxes and hazard
                                    insurance) to his or her gross monthly
                                    income, the intended occupancy of the
                                    subject property, the property type, and the
                                    purpose of the loan transaction to determine
                                    whether the mortgage loan generally meets
                                    the guidelines established for the program
                                    under which the applicant is applying. If
                                    there are multiple applicants on a loan
                                    transaction, Bank of America generally
                                    utilizes the Credit Score and/or Custom
                                    Mortgage Score associated with the highest
                                    wage-earner on the transaction as the
                                    representative score(s) for the transaction.
                                    The automated underwriting decision engine
                                    and/or the underwriter may utilize
                                    compensating factors to offset one or more
                                    features of the loan transaction that may
                                    not specifically comply with the product
                                    guidelines. Therefore, the application of
                                    the underwriting guidelines for a product
                                    type by either an underwriter or an
                                    automated decision engine does not imply
                                    that each specific standard was satisfied
                                    individually. A loan is considered to be
                                    underwritten in accordance with a given set
                                    of guidelines if, based on an overall
                                    qualitative evaluation, the loan is in
                                    substantial compliance with such
                                    underwriting guidelines.

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

Underwriting Guidelines  of Bank    As part of the underwriting evaluation, the
of America (Continued):             applicant's "Debt to Income Ratio" is
                                    calculated as the amount of the monthly debt
                                    obligations (including the proposed new
                                    housing payment and related expenses such as
                                    property taxes and hazard insurance) to his
                                    or her gross monthly income. Bank of
                                    America's Debt-to-Income Ratio guidelines
                                    are based on the loan instrument, loan term,
                                    Credit Score, Loan-to-Value Ratio, property
                                    type, and occupancy characteristics of the
                                    subject loan transaction. Bank of America
                                    permits ratios to exceed guidelines when the
                                    applicant has documented compensating
                                    factors for exceeding ratio guidelines such
                                    as documented excess funds in reserves after
                                    closing, a history of making a similar sized
                                    monthly debt payment on a timely basis,
                                    substantial residual income after monthly
                                    obligations are met, evidence that ratios
                                    will be reduced shortly after closing when a
                                    financed property under contract for sale is
                                    sold, or additional income has been verified
                                    for one or more applicants that is
                                    ineligible for consideration as qualifying
                                    income.

                                    For certain mortgage loans, underwriting may
                                    be based on data obtained by third parties
                                    that are involved at various stages in the
                                    mortgage origination or acquisition process.
                                    This typically occurs under circumstances in
                                    which loans are subject to more than one
                                    approval process, as when correspondents,
                                    certain mortgage brokers or similar entities
                                    that have been approved by Bank of America
                                    to underwrite loans on its behalf, or
                                    independent contractors hired by these
                                    parties to perform underwriting services on
                                    Bank of America's behalf, make initial
                                    determinations as to the consistency of
                                    loans with established underwriting
                                    guidelines. The underwriting of mortgage
                                    loans acquired from another lender generally
                                    relies on the representations from the
                                    originating lender that the mortgage loans
                                    were underwritten in accordance with agreed
                                    upon underwriting standards that are
                                    materially similar to Bank of America's. In
                                    the event these standards differ materially
                                    from those set forth in this prospectus, the
                                    related prospectus supplement will describe
                                    the applicable standards. Generally, Bank of
                                    America conducts a post-purchase review of a
                                    sampling of all mortgage loans acquired from
                                    another lender to determine whether agreed
                                    upon requirements were met. In order to be
                                    eligible to sell mortgage loans under a
                                    delegated underwriting arrangement, the
                                    lender must meet certain requirements
                                    including, among other things, certain
                                    quality, operational and financial
                                    guidelines.

                                    Certain of the mortgage loans may be
                                    purchased by Bank of America in negotiated
                                    transactions, and these negotiated
                                    transactions may be governed by contractual
                                    agreements. The contractual agreements may
                                    provide the commitment by Bank of America to
                                    accept the delivery of a certain dollar
                                    amount of mortgage loans over a specific
                                    period of time; this commitment may allow
                                    for the delivery of mortgage loans one at a
                                    time or in multiples as aggregated by the
                                    seller. Many of the contractual agreements
                                    allow the delegation of all underwriting
                                    functions to the seller, who will represent
                                    that the mortgage loans have been originated
                                    in accordance with underwriting standards
                                    agreed to by Bank of America.

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

Underwriting Guidelines of Bank     First lien purchase money mortgage loans may
of America (Continued):             have secondary financing to the borrower
                                    contemporaneously with the origination of
                                    the first lien mortgage loan. First lien
                                    refinance transactions may have existing
                                    secondary financing with the applicant that
                                    is resubordinated to the new first lien
                                    transaction or may have new secondary
                                    financing originated simultaneously with the
                                    first lien mortgage. The secondary financing
                                    may or may not be provided by Bank of
                                    America. The Total Loan-to-Value Ratio and
                                    Combined Loan-to-Value Ratio are evaluated
                                    on each loan with subordinate financing. The
                                    "Total Loan-to-Value Ratio" is the principal
                                    balance of the first lien mortgage loan at
                                    origination plus any secondary financing
                                    that was drawn upon at that time divided by
                                    the value of the mortgaged property. The
                                    "Combined Loan-to-Value Ratio" is the
                                    principal balance of the first lien mortgage
                                    loan at origination plus the total amount of
                                    available secondary financing (including any
                                    unused amount on a home equity line of
                                    credit) divided by the value of the
                                    mortgaged property. A mortgage loan with
                                    secondary financing is evaluated to
                                    determine if the Total Loan-to-Value Ratio
                                    and Combined Loan-to-Value Ratio meet the
                                    requirements for the program under which the
                                    application is submitted or if the
                                    application contains compensating factors to
                                    warrant an exception to the applicable
                                    guidelines. Some applicants request a first
                                    lien mortgage loan with a Loan-to-Value
                                    Ratio of 80% with a simultaneously funded
                                    second lien transaction in order to avoid
                                    the cost of primary mortgage insurance
                                    associated with first lien mortgage loans
                                    with Loan-to-Value Ratios exceeding 80%.

                                    verification) for all material data provided
                                    by the applicant, such as income and source
                                    of down payment, unless the applicant
                                    qualifies for one of the Accelerated

                                    verifications are required: a salaried
                                    applicant's income is verified by either
                                    having the applicant provide copies of the
                                    previous year's federal withholding form
                                    (IRS W-2) and a current payroll earnings
                                    statement or by sending a verification of
                                    employment form to the applicant's employer.
                                    A verification of employment form asks the
                                    employer to report the applicant's length of
                                    employment with the employer, the current

                                    be employed in the future. A self-employed
                                    applicant is required to provide copies of
                                    tax returns for the prior two years. Bank of

                                    obtaining bank or other financial statements

                                    confirming the existence of these funds,
                                    (ii) determining electronically that these

                                    other eligibility requirements. An applicant

                                    is only available through the wholesale

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

Underwriting Guidelines of Bank     Bank of America may originate new mortgage
of America (Continued):             loans under its "All-Ready Home" mortgage
                                    refinance program or its "Mortgage Rewards"
                                    refinance program. Under each of these
                                    programs, Bank of America will pay certain
                                    closing costs normally paid by the customer.
                                    Under these programs, a borrower whose
                                    current mortgage loan is serviced by Bank of
                                    America does not need to provide income or
                                    asset verification documentation if the
                                    current mortgage loan has had no 30 day or
                                    more delinquent payments in the previous
                                    twelve months (or since origination if less
                                    than twelve months). In addition, Bank of
                                    America typically requires only a drive-by
                                    appraisal rather than a an interior
                                    inspection appraisal. Because these programs
                                    involve the refinancing of mortgage loans
                                    that Bank of America originally underwrote,
                                    Bank of America will not apply any
                                    significant borrower credit or property
                                    underwriting standards (other than a minimum
                                    Credit Score). Mortgage Loans initially
                                    included in the Trust Estate for a
                                    particular series may have been the subject
                                    of a refinancing described above. To the
                                    extent a borrower becomes eligible for the
                                    All-Ready Home or Mortgage Rewards program
                                    after his or her Mortgage Loan has been
                                    included in a particular Trust Estate, his
                                    or her Mortgage Loan could be more easily
                                    refinanced, resulting in a prepayment of the
                                    Mortgage Loan.

                                    For a description of the No Ratio and Stated
                                    Income programs, see "--Bank of America
                                    Alternative Underwriting Standards" below.

                                    Collateral Valuation
                                    --------------------
                                    Bank of America conducts a valuation of the
                                    mortgaged property as collateral for each
                                    mortgage loan. This collateral valuation may
                                    be determined by (i) an interior inspection
                                    appraisal, (ii) a tax assessed value, (iii)
                                    a desktop appraisal, (iv) a drive-by
                                    appraisal, (v) an automated valuation model,
                                    or (vi) reference to the collateral
                                    valuation obtained in connection with the
                                    origination of the previous loan if the loan
                                    is a refinance of a mortgage loan that was
                                    previously serviced by Bank of America. An
                                    interior inspection appraisal is an
                                    appraisal report based on an interior
                                    inspection of the subject property. A tax
                                    assessed value is a factor applied to the
                                    tax value recorded for the subject property
                                    that reflects the general relationship
                                    between the assessed value and the market
                                    value of the property. These factors are
                                    established for each county by a third party
                                    vendor. A tax assessed value also does not
                                    entail any physical inspection of the
                                    subject property. A desktop appraisal is a
                                    report completed by a certified/licensed
                                    appraiser utilizing a sales comparison
                                    analysis from a local multiple listing
                                    service without conducting a physical
                                    inspection of the property. A drive-by
                                    appraisal report is a limited, summary
                                    appraisal report based on an exterior
                                    inspection of the property and comparable
                                    sales by a certified/licensed appraiser. An
                                    automated valuation model is an
                                    electronically generated valuation that
                                    utilizes real estate information such as
                                    property characteristics, market
                                    demographics, sales price data, and regional
                                    trends to calculate a value for a specific
                                    property. Bank of America utilizes the
                                    automated valuation models of several
                                    vendors. An automated valuation model does
                                    not entail any physical inspection of the
                                    subject property. In addition, no updated
                                    appraisal valuation may be performed if the
                                    loan is a refinance of a loan that was
                                    previously serviced by Bank of America and
                                    the valuation from the time of origination
                                    of the loan being refinanced reflects
                                    adequate value for the mortgaged property.

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

Underwriting Guidelines of Bank     In certain instances, the interior, desktop
of America (Continued):             or drive-by appraisal reports may be
                                    conducted by an employee of Bank of America
                                    or an affiliate. The appraisal report,
                                    however, may be performed by an independent
                                    appraiser contracted by Bank of America or
                                    an affiliate of Bank of America on direct
                                    channel originations. Appraisal reports on
                                    indirect channel originations are generally
                                    performed by an appraiser selected by the
                                    originating lender but indirect channel
                                    appraisers cannot be performed by appraisers
                                    that have been deemed to be ineligible to
                                    perform appraisals by Bank of America.

                                    Appraisers may note on their appraisal any
                                    environmental hazard the appraiser becomes
                                    aware of while appraising the property. EPA
                                    Lead Paint requirements for notice and an
                                    inspection period are standard for
                                    properties built before 1978. Properties
                                    containing other hazards may be eligible for
                                    financing if the appraiser can value the
                                    property showing the impact of the hazard,
                                    and the borrower executes a "hold harmless"
                                    letter to the lender. Environmental hazards
                                    are not noted on collateral valuations where
                                    no physical inspection of the property takes
                                    place, such as on loans where the collateral
                                    valuation is conducted by an automated

                                    on a desktop appraisal if they generally are

                                    Certain states have "anti-deficiency" laws
                                    which, in general, require lenders providing
                                    credit on one to four family properties to
                                    look solely to the property for repayment in
                                    the event of foreclosure. The underwriting
                                    guidelines in all states (including anti
                                    deficiency states) require that the value of
                                    the property being financed, as indicated by
                                    the collateral valuation, currently supports
                                    and is anticipated to support in the future
                                    the outstanding loan balance and provides
                                    sufficient value to mitigate the effects of
                                    adverse shifts in real estate values,
                                    although there can be no assurance that the
                                    value will support the outstanding loan
                                    balance in the future.

                                    Flood Determinations and Hazard Insurance
                                    -----------------------------------------

                                    Each mortgage loan is evaluated to determine
                                    if the subject property is located in a
                                    federal flood zone. If the property is
                                    located in a flood zone, then flood
                                    insurance is required on the loan
                                    transaction with an amount of coverage that
                                    meets or exceeds federal law requirements.
                                    Generally, evidence of acceptable hazard
                                    insurance coverage on the subject property
                                    is a requirement for loan approval. This
                                    documentation, however, is not required if
                                    the mortgage loan is a refinance of an
                                    existing Bank of America serviced loan
                                    transaction and hazard insurance was
                                    documented for the previous loan transaction
                                    or the mortgage loan is originated under a
                                    program that does not require the review of
                                    evidence of hazard insurance.

                                    Mortgage Insurance and Title
                                    ----------------------------
Underwriting Guidelines of Bank     Mortgage loans originated with Loan-to-Value
of America (Continued):             Ratios in excess of 80% may be covered by
                                    primary mortgage insurance. Except as noted
                                    below in connection with certain refinance
                                    transactions, mortgage loans will generally
                                    be covered by an appropriate standard form
                                    American Land Title Association ("ALTA")
                                    title insurance policy, or a substantially

                                    acceptable to Fannie Mae or Freddie Mac, or
                                    if the related mortgaged property is located
                                    in a jurisdiction where these policies are
                                    generally not available, an opinion of
                                    counsel of the type customarily rendered in
                                    these jurisdiction in lieu of title
                                    insurance will be obtained instead. If
                                    required, the title insurance policy may
                                    include environmental protection lien
                                    endorsement coverage (ALTA Form 8.1 or its
                                    equivalent) excepting only Superliens which
                                    may arise after the loan is made.

                                    Mortgage loans on refinance transactions
                                    generally do not contain title insurance
                                    policies. Title searches are often performed
                                    on these refinance transactions in lieu of
                                    obtaining a title insurance policy. A title
                                    search is a limited search of a specified
                                    parcel of land summarizing information

                                    Borrowers Protection Plan(R)
                                    ----------------------------

                                    Bank of America's Borrowers Protection
                                    Plan(R) ("BPP") is a debt-cancellation
                                    contract between the borrower and Bank of
                                    America. This optional plan can cancel a
                                    borrower's monthly principal and interest
                                    payment for up to a total of twelve months
                                    if the borrower loses his or her job or
                                    becomes disabled. Additionally, the
                                    outstanding principal balance of a mortgage
                                    loan with BPP will be cancelled if the
                                    borrower dies as a result of an accident.
                                    While Bank of America will cancel payment of
                                    the principal, interest and BPP fees, the
                                    borrower will still be responsible for the
                                    payment of taxes and insurance. Bank of
                                    America will be obligated to pay to the
                                    applicable Trust any amounts cancelled due
                                    to BPP on a Mortgage Loan.

                                    The following three protection options are
                                    available in a BPP contract: (i) disability,
                                    involuntary unemployment and accidental
                                    death; (ii) involuntary unemployment and
                                    accidental death or (iii) disability and
                                    accidental death.

                                    The benefit period ranges from six to twelve
                                    months. A borrower may elect single (i.e.,
                                    one borrower who is named in the mortgage
                                    note) or joint coverage (i.e., any two of
                                    the borrowers named in the mortgage note).

                                    BPP is only available on certain first-lien
                                    fixed-rate and adjustable-rate mortgage loan
                                    products and programs. The term of
                                    protection is the lesser of the loan term
                                    and ten years. Upon expiration, BPP is
                                    discontinued and the monthly BPP fee is no
                                    longer assessed. If the borrower has an
                                    active BPP claim prior to the expiration
                                    date, however, loan protection can extend
                                    beyond the expiration date. BPP is optional
                                    and the borrower's choice regarding BPP is
                                    not considered when evaluating the loan
                                    request. The borrower must select the BPP
                                    plan prior to loan closing.

                                    o     Conversely, if prevailing interest
                                          rates for similar mortgage loans rise
                                          above the interest rates on the

                                    determined that these amounts, if advanced,
                                    would be nonrecoverable), will adversely
                                    affect the yield on the related Senior

                                    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

                                    related Senior Certificates.

                                    Net interest shortfalls will adversely
                                    affect the yields on the Offered

                                    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

                                    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.

                                    in general. Therefore, credit scores do not
                                    address particular mortgage loan
                                    characteristics that influence the

                                    relied upon as a basis for an expectation
                                    that a borrower will repay its mortgage loan

                                    assumed prepayment rate. The actual rates of
                                    prepayment on the applicable Mortgage Loans
                                    are likely to differ from the rates assumed.
                                    If prepayments on the applicable Mortgage
                                    Loans occur at a rate slower than the rates
                                    used in determining the notional amounts
                                    specified in the related Yield Maintenance
                                    Agreement, the Class Balance(s) of the
                                    applicable Certificates will be greater than
                                    the related notional amount for a
                                    Distribution Date. For any Distribution Date
                                    on which the notional amount is lower than
                                    the actual Class Balance(s) of the related
                                    Certificates, the Yield Maintenance Amount
                                    will be greater than the payment the
                                    Counterparty is required to make under the
                                    applicable Yield Maintenance Agreement for
                                    such Distribution Date and therefore, a
                                    holder of the related Certificate may not
                                    receive its full Yield Maintenance Amount
                                    for such Distribution Date. However, to the
                                    extent that a holder of a class of related
                                    Certificates does not receive the full Yield
                                    Maintenance Amount for a Distribution Date,
                                    such shortfall may be paid to the related
                                    class of Certificates from amounts in the

There is a Risk that Interest       When a Mortgage Loan is prepaid in full, the
Payments on the Mortgage Loans      mortgagor is charged interest only up to the
May Be Insufficient to Pay          date on which payment is made, rather than
Interest on Your Certificates:      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

                                    but in each case only up to the amount of

                                    Mortgage Loans for such Distribution Date.
                                    To the extent these shortfalls are not

                                    Compensating Interest, they will be

                                    There are, however, limited obligations of
                                    the Depositor with respect to certain
                                    breaches of representations and warranties,

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 a
                                    secondary market will develop or, if it does
                                    develop, that it will provide you with
                                    liquidity of investment or that it will
                                    continue for the life of the Offered
                                    Certificates. As a result, you may not be
                                    able to sell your Certificates 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

of Loss:                            A" underwriting guidelines. See

                                    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

                                  Risk Factors
                                  ------------

The Rate of Default on Mortgage     Certain of the Mortgage Loans may be secured
Loans that Are Secured by Investor  by investor properties. An investor property
Properties May be Higher than on    is a property which, at the time of
Other Mortgage Loans:               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         At the time of origination of certain of the
Mortgaged Properties Subject to     Mortgage Loans, a lender other than the
Second Lien Mortgage                Sponsor may have originated a second lien
Loans:                              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        The Subordinate Certificates may provide
Provide Subordination for           credit support for more than one Groups of
All Groups                          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 Senior Certificates.

                                    Under certain circumstances due to a
                                    cross-collateralization mechanism, principal
                                    otherwise payable to these Subordinate
                                    Certificates will be paid to certain Senior

                                    entitled to receive a specified percentage
                                    of the principal payments that are
                                    distributable to the Senior Certificates or
                                    applicable group of Senior Certificates
                                    (other than any Ratio Strip Certificates) in
                                    the aggregate on a Distribution Date and
                                    that is not designated as a Class of
                                    Sequential Pay Certificates.

Planned Amortization
   Certificates (also sometimes
   referred to as "PAC
   Certificates") ................  A Class of Certificates that is designed to
                                    receive principal payments using a
                                    predetermined principal balance schedule
                                    derived by assuming two constant prepayment
                                    rates for the underlying Mortgage Loans.
                                    These two rates are the endpoints for the
                                    "structuring range" for a Class of Planned
                                    Amortization Certificates. The Classes of
                                    Planned Amortization Certificates in any
                                    series may be subdivided into different
                                    categories (e.g., Planned Amortization I
                                    Certificates or PAC I Certificates, Planned
                                    Amortization II Certificates or PAC II
                                    Certificates and so forth) derived using
                                    different structuring ranges and/or payment
                                    priorities. A Class of PAC Certificates is
                                    designed to provide protection against
                                    prepayments occurring at a constant rate
                                    within the structuring range.

Ratio Strip Certificates .........  A Class of Certificates that is entitled to
                                    receive a constant proportion, or "ratio
                                    strip," of the principal payments on the
                                    underlying Mortgage Loans.

Scheduled Amortization
   Certificates ..................  A Class of Certificates that is designed to
                                    receive principal payments using a
                                    predetermined principal balance schedule but
                                    is not designated as a Class of Planned
                                    Amortization Certificates or Targeted
                                    Amortization Certificates. The schedule is
                                    derived by assuming either two constant
                                    prepayment rates or a single constant
                                    prepayment rate for the underlying Mortgage
                                    Loans. In the former case, the two rates are
                                    the endpoints for the "structuring range"
                                    for a Class of Scheduled Amortization
                                    Certificates and the range generally is
                                    narrower than that for a Class of Planned
                                    Amortization Certificates. Typically, the
                                    Companion Certificates for the applicable
                                    series of Certificates generally will
                                    represent a smaller percentage of a Class of
                                    Scheduled Amortization Certificates than the
                                    Companion Certificates generally would
                                    represent in relation to a Class of Planned
                                    Amortization Certificates or Targeted
                                    Amortization Certificates. A Class of
                                    Scheduled Amortization Certificates is
                                    generally less sensitive to prepayments than
                                    a Class of Companion Certificates, but more
                                    sensitive than a Class of Planned
                                    Amortization Certificates or Targeted
                                    Amortization Certificates.

                                    principal until they are retired. A Class of
                                    Sequential Pay Certificates may receive
                                    principal payments concurrently with one or

   Certificates") ................  A Class of Certificates that is designed to
                                    receive principal payments using a
                                    predetermined principal balance schedule
                                    derived by assuming a single constant
                                    prepayment rate for the underlying Mortgage
                                    Loans. A Class of TAC Certificates is

                                    constant prepayment rate used to derive that
                                    Class's principal balance schedule.

Special Retail Certificates.......  Although there can be no assurance as to the
                                    rate at which principal distributions will
                                    be made on any class of Offered
                                    Certificates, special retail certificates,
                                    in particular, may be inappropriate
                                    investments for you if you require a
                                    distribution of a particular amount of
                                    principal on a specific date or an otherwise
                                    predictable stream of distributions. If you
                                    own special retail certificates, funds
                                    available for distributions of principal may
                                    not be sufficient to permit the
                                    distributions you request within any
                                    specific period of time after your request.
                                    During periods in which prevailing interest
                                    rates are generally higher than the
                                    pass-through rate for a class of special
                                    retail certificates, greater numbers of
                                    beneficial owners may request distributions
                                    of principal in respect of the special
                                    retail certificates to take advantage of
                                    higher interest rates. During such periods
                                    there may, however, be a concurrent
                                    reduction in the rate of prepayments of the
                                    related Mortgage Loans, thus limiting the
                                    funds available for such distributions.

                                    In addition, because of the random lot

                                    may receive a principal distribution on your

                                    requested such a distribution) if the amount
                                    available for distribution in respect of
                                    principal on such Distribution Date on a
                                    class of special retail certificates exceeds
                                    the aggregate amount requested for

                                    the class of special retail certificates. It
                                    is more likely that amounts will be
                                    distributed by random lot during the periods
                                    of the relatively low interest rates and,
                                    correspondingly, higher prepayment rates.
                                    Under such circumstances you may have
                                    difficulty reinvesting these principal
                                    distributions at rates as high as the
                                    pass-through rate of your Certificates or
                                    your expected yield.

                                    rate that resets periodically based upon a
                                    designated index and that varies directly
                                    with changes in that index.

Interest Only Certificates .......  A Class of Certificates that is entitled to
                                    receive some or all of the interest payments
                                    made on the Mortgage Loans and little or no
                                    principal. Interest Only Certificates have
                                    either a nominal Class Balance or a notional
                                    amount. A nominal Class Balance represents
                                    actual principal that will be paid on the
                                    Class. It is referred to as nominal since it
                                    is extremely small compared to other
                                    Classes. A notional amount is the amount
                                    used as a reference to calculate the amount
                                    of interest due on a Class of Interest Only
                                    Certificates that is not entitled to any
                                    distributions in respect of principal.

Inverse Floating Rate
   Certificates ..................  A Class of Certificates with an interest
                                    rate that resets periodically based upon a
                                    designated index and that varies inversely
                                    with changes in that index and with changes
                                    in the interest rate payable on the related
                                    Class of Floating Rate Certificates.

Principal Only Certificates ......  A Class of Certificates that does not bear
                                    interest and is entitled to receive only
                                    distributions of principal.

      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. Because the
asset-backed securities are subject to modification or revision, 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.
