    The BankAmerica Manufactured Housing Contract Trust V Senior/Subordinate
Pass-Through Certificates, Series 1998-2 (the "Certificates") will represent
interests in a pool (the "Contract Pool") of actuarial manufactured housing
installment sales contracts and installment loan agreements (the "Contracts")
and certain related property (the Contracts and such related property being
referred to as the "Trust Fund"). The Contracts will be conveyed to the Trust
Fund by Bank of America National Trust and Savings Association ("Bank of
America, NT&SA") and Bank of America, FSB. Each Contract was originated or
purchased by either Security Pacific Financial Services of California, Inc.
("SPFSC"), a wholly-owned subsidiary of Bank of America, NT&SA, or by Bank of
America, FSB, acting through its division, BankAmerica Housing Services, in each
case on an individual basis in the ordinary course of its business. Bank of
America, FSB, acting through its division, BankAmerica Housing Services, will
serve as servicer of the Contracts (together with any successor servicer, the
"Servicer"). The term "approximate," with respect to the aggregate principal
amount of any Certificates or Contracts, means that the amount is subject to a
variance of plus or minus 5%. Terms used and not otherwise defined herein have
the respective meanings ascribed to such terms in the Prospectus dated June 16,
1998 attached hereto (the "Prospectus").
 
    The Certificates will consist of eight classes of senior certificates
(collectively, the "Senior Certificates") designated as the Class A-1
Certificates, the Class A-2 Certificates, the Class A-3 Certificates, the Class
A-4 Certificates, the Class A-5 Certificates, the Class A-6 Certificates, the
Class A-7 Certificates and the Class A-8 Certificates and four classes of
subordinate certificates designated as the Class M Certificates, the Class B-1
Certificates, the Class B-2 Certificates and the Class R Certificates
(collectively, the "Subordinate Certificates"). Only the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8, Class M and
Class B-1 Certificates (collectively, the "Offered Certificates") are being
offered hereby. The Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class
A-6, Class A-7, Class A-8, Class M and Class B-1 Certificates will evidence in
the aggregate approximate initial 6.97%, 11.52%, 9.33%, 11.37%, 6.41%, 10.06%,
16.91%, 9.43%, 7.50%, and 6.00% undivided interests, respectively, in the
Contract Pool. The Class B-2 Certificates will evidence in the aggregate an
approximate initial 4.50% undivided interest in the Contract Pool. The Class B-1
and Class B-2 Certificates are referred to collectively as the "Class B
Certificates" herein.
 
    Distributions of principal and interest on the Certificates will be made to
the holders of the Certificates on the 10th day of each month (or if the 10th
day is not a business day, the next business day) (each, a "Distribution Date"),
beginning in July, 1998. The Class A-1, Class A-2, Class A-3, Class A-4, Class
A-5 and Class A-6 Certificates will have the respective fixed Pass-Through Rates
specified above. The Pass-Through Rates for the Class A-7, Class A-8, Class M
and Class B-1 Certificates are subject to a maximum rate equal to the Weighted
Average Net Contract Rate. See "Description of the Certificates" herein.
 
    The rights of the Subordinate Certificateholders to receive distributions of
principal and interest are subordinated as described herein to such rights of
the Senior Certificateholders, the rights of Class B-2 and Class R
Certificateholders to receive distributions are subordinated as described herein
to such rights of the Class B-1 and Class M Certificateholders, and the rights
of Class B-1 Certificateholders to receive distributions are subordinated as
described herein to such rights of the Class M Certificateholders. See
"Description of the Certificates" herein.
 
    The yields to maturity of the Offered Certificates may vary from the
anticipated yields to the extent such Certificates are purchased at a discount
or premium and to the extent the rate and timing of payments thereon are
sensitive to the rate and timing of principal payments (including prepayments)
of the Contracts. See "Risk Factors" herein.
 
    It is a condition to the issuance of the Offered Certificates that each
Class of Senior Certificates be rated "Aaa" by Moody's Investors Service, Inc.
("Moody's") and "AAA" by Fitch IBCA, Inc. ("Fitch"), that
 
                                       ii
<PAGE>
the Class M Certificates be rated at least "Aa3" by Moody's and "AA-" by Fitch
and that the Class B-1 Certificates be rated at least "Baa2" by Moody's and
"BBB" by Fitch.
 
    An election will be made to treat the Trust Fund as a real estate mortgage
investment conduit (a "REMIC") for federal income tax purposes. The
Certificates, other than the Class R Certificates, will represent "regular
interests" in the REMIC. See "Certain Federal Income Tax Consequences" herein
and in the Prospectus.
 
    There is currently no market for the Offered Certificates. The underwriters
named herein (the "Underwriters") intend to make a secondary market in the
Offered Certificates, but have no obligation to do so. There can be no assurance
that a secondary market for the Offered Certificates will develop, or if it does
develop, that it will continue or provide sufficient liquidity. See "Risk
Factors" herein and in the Prospectus.

offering of the Offered Certificates. Additional information is contained in the
Prospectus and purchasers are urged to read both this Prospectus Supplement and
the Prospectus in full. Sales of the Offered Certificates may not be consummated
unless the purchaser has received both this Prospectus Supplement and the

meanings ascribed to such terms in the Prospectus.
 
    This Prospectus Supplement may be used by BancAmerica Robertson Stephens, an
affiliate of the Sellers and Servicer, in connection with offers and sales
related to market making transactions in the Offered Certificates. BancAmerica
Robertson Stephens may act as principal or agent in such transactions. Such

                                    Pool. The "Net Contract Rate" of a Contract equals the
                                    rate of interest borne by such Contract minus the Annual
                                    Servicing Rate. The "Annual Servicing Rate" is equal to
                                    1.00%. Interest on each Class of Certificates will be
                                    calculated on the basis of a 360-day year comprised of

                                    for any Class is equal to the sum of (i) one month's
                                    interest at the Pass-Through Rate for that Class on the
                                    Certificate Balance of that Class and (ii) any
                                    previously undistributed shortfalls in interest due to
                                    the Certificateholders of that Class in respect of prior
                                    Distribution Dates. Any shortfall in interest due to
                                    Certificateholders will, to the extent legally

                                    of a Distribution Date equals the sum of (a) the Total
                                    Regular Principal Amount (as defined below) for such
                                    Distribution Date and (b) any previously undistributed
                                    shortfalls in the distribution of the Total Regular
                                    Principal Amount in respect of prior Distribution Dates.
 
                                    The "Total Regular Principal Amount" on each
                                    Distribution Date is the sum of (i) the Scheduled
                                    Principal Reduction Amount (defined below) for such
                                    Distribution Date, (ii) the Scheduled Principal Balance

                                    be, on account of certain breaches of representations
                                    and warranties made by it in the Agreement, (iii) all
                                    partial prepayments received during such related

                                    of each Contract that was prepaid in full during such

                                    Principal Balance of each Contract that became a
                                    Liquidated Contract (defined below) during such related

                                    The "Scheduled Principal Balance" of a Contract for any
                                    Distribution Date is its principal balance as of the Due
                                    Date in the Collection Period immediately preceding such
                                    Distribution Date, after giving effect to all previous
                                    partial prepayments, all previous scheduled principal
                                    payments (whether or not paid) and the scheduled
                                    principal payment due on such Due Date, but without
                                    giving effect to any adjustment due to bankruptcy or

                                    The "Scheduled Principal Reduction Amount" for any
                                    Distribution Date is an approximate calculation

                                    Liquidated Contract includes any defaulted Contract in
                                    respect of which the related Manufactured Home has been
                                    realized upon and disposed of and the proceeds of such

                                    Distribution Date is the sum of the Certificate Balances
                                    of the Senior Certificates immediately prior to such
                                    Distribution Date. The "Subordinate Certificate Balance"
                                    as of any Distribution Date is the sum of the Class M
                                    Certificate Balance, Class B-1 Certificate Balance and
                                    the Class B-2 Certificate Balance immediately prior to
                                    such Distribution Date. In no event shall the aggregate
                                    distributions of principal to the holders of any class
                                    of Offered Certificates and the Class B-2 Certificates
                                    exceed the Initial Certificate Balances for such Class
                                    of Offered Certificates or the Initial Class B-2
                                    Certificate Balance, respectively.
 
Reserve Account...................  On the Closing Date, the Trustee shall establish an
                                    account (the "Reserve Account") for the benefit of the
                                    Certificateholders. The Reserve Account shall have an
                                    initial balance of $6,859,826 (1.00% of the Cut-off Date
                                    Pool Principal Balance) on the Closing Date. In the
                                    event that amounts on deposit in the Reserve Account
                                    fall below the Reserve Account Cap, the Reserve Account
                                    will be replenished on each Distribution Date by certain
                                    excess interest collections on or in respect of the
                                    Contracts, if any, remaining after all required
                                    distributions to the Senior, Class M and Class B
                                    Certificateholders and after the payment of the Monthly
                                    Servicing Fee and the reimbursement of Monthly Advances
                                    have been made on such Distribution Date; provided that
                                    the amount on deposit in the Reserve Account shall not
                                    exceed the Reserve Account Cap. The Reserve Account Cap
                                    is equal to $6,859,826 or if there has been a Reserve
                                    Account Trigger and such Reserve Account Trigger has not
                                    been cured, $13,719,652 (2.00% of the Cut-off Date Pool
                                    Principal Balance). See "Description of the
                                    Certificates-- Reserve Account" herein for a description
                                    of the Reserve Account Triggers and the Reserve Account

                                    protection against losses on Liquidated Contracts.
 
                                    The protection afforded to the holders of Senior

                                    Certificateholders by the subordination of the Class B
                                    Certificates and to the Class B-1 Certificateholders by
                                    the subordination of the Class B-2 Certificates (in each
                                    case, to the extent described herein) will be
                                    accomplished by the application of the Available

Losses on Liquidated Contracts....  As described above, the Total Regular Principal Amount
                                    distributable to the holders of the Series 1998-2
                                    Regular Certificates on each Distribution Date includes
                                    the Scheduled Principal Balance of each Contract that
                                    became a Liquidated Contract during the immediately
                                    preceding Collection Period. The Liquidation Proceeds,
                                    net of (i) certain expenses incurred to liquidate such
                                    Liquidated Contract, (ii) all accrued and unpaid
                                    interest thereon and (iii) all Monthly Advances (as
                                    defined below) required to be made in respect of such
                                    Liquidated Contract (the "Net Liquidation Proceeds"),
                                    may be less than the Scheduled Principal Balance of such
                                    Liquidated Contract. Under such circumstances, the loss
                                    on the Liquidated Contract, in the amount of the
                                    deficiency between the Net Liquidation Proceeds and the
                                    Scheduled Principal Balance of such Liquidated Contract,
                                    may be covered to the extent of the amount (the "Excess
                                    Interest"), if any, by which the interest collected on
                                    nondefaulted Contracts during the same Collection Period
                                    exceeds the sum of (i) interest distributions due to the
                                    holders of the Series 1998-2 Regular Certificates and
                                    (ii) the Monthly Servicing Fee.
 
                                    The effect of any losses on Liquidated Contracts during
                                    a Collection Period in excess of the (i) Excess
                                    Interest, if any, and (ii) the funds, if any, on deposit
                                    in the Reserve Account generally will reduce scheduled
                                    interest payments on the Class B-2 Certificates, the
                                    Class B-1 Certificates and the Class M Certificates, in
                                    that order, and may reduce the Pool Scheduled Principal
                                    Balance below the aggregate Certificate Balance of the
                                    Certificates on the related Distribution Date. In the
                                    event the Pool Scheduled Principal Balance falls below
                                    the aggregate Certificate Balance of the Certificates on
                                    any Distribution Date, shortfalls and/or losses will
                                    arise with respect to the Certificates, which shortfalls
                                    and/or losses will be borne by the Class B-2
                                    Certificateholders, the Class B-1 Certificateholders,
                                    the Class M Certificateholders and the Senior
                                    Certificateholders, in that order.
 
Monthly Advances..................  For each Distribution Date, the Servicer will be
                                    obligated to make an advance (a "Monthly Advance") equal
                                    to the lesser of (i) delinquent scheduled payments of
                                    principal and interest on the Contracts that were due in
                                    the preceding Collection Period and (ii) the amount, if
                                    any, by which scheduled distributions of principal and
                                    interest due on the Series 1998-2 Regular Certificates
                                    exceeds certain amounts on deposit in the Certificate
                                    Account (as hereinafter defined) as of the last day of
                                    the immediately preceding Collection Period, except to
                                    the extent, in the Servicer's judgment, such advance
                                    would not be recoverable from related late payments,
                                    Liquidation Proceeds or otherwise. Advances are
                                    reimbursable to the Servicer as

                                    the Trustee of the mortgage or deed of trust securing
                                    each Land Home and Land-in-Lieu Contract. In some
                                    states, in the absence of such a notation or amendment
                                    or recordation of assignment, the assignment to the
                                    Trustee of the security interest in the Manufactured
                                    Homes or the mortgage or deed of trust securing a Land
                                    Home or Land-in-Lieu Contract may not be effective
                                    against creditors of Bank of America, FSB. However,
                                    neither Seller will be obligated to repurchase or
                                    substitute a Contract solely on the basis of the failure
                                    by Bank of America, FSB to cause any such notation or
                                    amendment to be made with respect to a document of title
                                    or UCC financing statement relating to a Manufactured

                                    Certificates--Conveyance of Contracts."
 
                                    Under the Agreement, each of the Sellers will agree to
                                    repurchase, or at its option substitute another contract
                                    for, a Contract sold by it if it has failed to perfect a
                                    first-priority security interest in such Manufactured

                                    creditors or assignees of the Contracts, unless such
                                    failure does not materially and adversely affect the
                                    Trustee's interest in the Contract or such failure has
                                    been cured.

                                    Contract has been assigned to the Trustee.
 
Optional Termination and
  Termination Auction.............  The Servicer has the option to purchase from the Trust
                                    Fund all Contracts then outstanding and all other

                                    conditions, the Pool Scheduled Principal Balance is less
                                    than 10% of the Cut-off Date Pool Principal Balance. See

Federal Income Tax Consequences...  For federal income tax purposes, an election will be
                                    made to treat certain assets of the Trust Fund as a real
                                    estate mortgage investment conduit ("REMIC"). The Series
                                    1998-2 Regular Certificates will constitute "regular
                                    interests" in the REMIC and generally will be treated as
                                    debt instruments of the Trust Fund for federal income
                                    tax purposes. The Series 1998-2 Residual Certificates
                                    will be treated as the "residual interest" in the REMIC
                                    for federal income tax purposes. Holders of the Series
                                    1998-2 Regular Certificates that would otherwise report
                                    income under a cash method of accounting will be
                                    required to include in income interest on the Series
                                    1998-2 Regular Certificates (including original issue
                                    discount ("OID"), if any) in accordance with the accrual
                                    method of accounting. See "Certain Federal Income Tax
                                    Consequences" herein and in the Prospectus.
 
ERISA Considerations..............  SENIOR CERTIFICATES.  Subject to the conditions and
                                    discussion set forth herein, the Senior Certificates may
                                    be purchased by employee benefit or other plans that are
                                    subject to the Employee Retirement Income Security Act
                                    of 1974, as amended ("ERISA"), and/or Section 4975 of
                                    the Internal Revenue Code of 1986 (the "Code"). See
                                    "ERISA Considerations" herein and in the Prospectus.
 
                                    SUBORDINATE CERTIFICATES.  Unless the opinion referred
                                    to under "ERISA Considerations--Class M and Class B-1
                                    Certificates" is delivered to the Trustee, an employee
                                    benefit or other plan subject to ERISA and/or Section
                                    4975 of the Code will not be permitted to purchase or
                                    hold the Class M or the Class B Certificates as such
                                    actions may give rise to a non-exempt prohibited
                                    transaction under ERISA or Section 4975 of the Code.
                                    However, an insurance company investing assets of its
                                    general account may purchase and hold the Class M or the
                                    Class B Certificates if it delivers the required
                                    certification to the Trustee. See "ERISA Considerations"
                                    herein and in the Prospectus.
 
Legal Investment..................  The Senior Certificates and the Class M Certificates at
                                    the time of issuance will qualify as "mortgage related
                                    securities" under the Secondary Mortgage Market
                                    Enhancement Act of 1984, as amended ("SMMEA") and, as
                                    such, will constitute legal investments for certain
                                    types of investors to the extent provided in SMMEA. Such
                                    institutions should consult their own legal advisors in
                                    determining whether and to what extent the Senior
                                    Certificates and the Class M Certificates constitute
                                    legal investments for such investors.
 
                                    Because the Class B-1 Certificates will not, at the time
                                    of issuance, be rated in one of the two highest rating
                                    categories of Moody's and Fitch, the Class B-1
                                    Certificates will not constitute "mortgage related
                                    securities" for purposes of SMMEA.

                                    Accordingly, many institutions with legal authority to
                                    invest in more highly rated securities based on
                                    manufactured housing obligations may not be legally
                                    authorized to invest in the Class B-1 Certificates. No
                                    representation is made as to any regulatory requirements
                                    or considerations (including without limitation
                                    regulatory capital or permissible investment
                                    requirements) applicable to the purchase of the Class
                                    B-1 Certificates by banks, savings and loan associations
                                    or other financial institutions. Such institutions
                                    should consult their own legal advisors in determining
                                    whether and to what extent the Offered Certificates
                                    constitute legal investments for such investors.
 
Rating............................  It is a condition to the issuance of the Offered
                                    Certificates that each Class of Senior Certificates be
                                    rated "Aaa" by Moody's and "AAA" by Fitch, that the
                                    Class M Certificates be rated at least "Aa3" by Moody's
                                    and "AA-" by Fitch and that the Class B-1 Certificates
                                    be rated at least "Baa2" by Moody's and "BBB" by Fitch.
                                    The Seller has not requested ratings on the Offered
                                    Certificates by any rating agency other than Moody's and
                                    Fitch. However, there can be no assurance as to whether
                                    any other rating agency will rate any or all of the
                                    Offered Certificates, or if it does, what rating would
                                    be assigned by any such other rating agency. A rating on
                                    any or all of the Offered Certificates by certain other
                                    rating agencies, if assigned at all, may be lower than
                                    the rating assigned to such Certificates by Moody's and
                                    Fitch. See "Ratings" herein and in the Prospectus.
 
                                    A security rating is not a recommendation to buy, sell
                                    or hold securities and may be subject to revision or
                                    withdrawal at any time.

                                  RISK FACTORS
 
    The discussion under "Risk Factors" in the Prospectus should be read
carefully in connection with a decision to invest in any of the Offered
Certificates. The following discussion supplements, and does not replace or
supersede the discussion under "Risk Factors" in the Prospectus, unless the
context expressly so provides.
 
    1. LIMITED LIQUIDITY. Only the Offered Certificates are being offered
hereby. The Underwriters intend to make a secondary market in the Offered
Certificates, but have no obligation to do so. There can be no assurance that a
secondary market will develop for the Offered Certificates or, if it does
develop, that it will provide the holders of any Class of Offered Certificates
with liquidity of investment or that it will remain for the term of such Class
of Offered Certificates.
 
    The Class B-1 Certificates will not constitute "mortgage related securities"
for purposes of SMMEA. Accordingly, many institutions with legal authority to
invest in SMMEA securities will not be able to invest in the Class B-1
Certificates, limiting the market of such securities.
 
    2. DISTRIBUTIONS OF PRINCIPAL. The yield to maturity on the Class M and
Class B-1 Certificates will be affected by the rate at which Contracts become
Liquidated Contracts and the severity of ensuing losses on such Liquidated
Contracts and the timing thereof. No payments of principal will be made to the
holders of the Class M Certificates until the Senior Certificate Balance has
been reduced to zero, no payments of principal will be made to the holders of
the Class B-1 Certificates until the Class M Certificate Balance has been
reduced to zero and no payments of principal will be made to the holders of the
Class B-2 Certificates until the Class B-1 Certificate Balance has been reduced
to zero. It is not possible to predict the timing of the occurrence of the
Distribution Date, if any, on which the Senior Certificate Balance or the Class
M Certificate Balance, as applicable, will be reduced to zero, which occurrences
will be affected by the rate of voluntary prepayments in addition to prepayments
due to default and subsequent liquidation. Prepayments on Contracts may be
influenced by a variety of economic, geographic, social and other factors,
including repossessions, aging, seasonality, market interest rates, changes in
housing needs, job transfers and unemployment. See "Prepayment and Yield
Considerations" herein and in the Prospectus.
 
    3. NO RECOURSE. Neither Bank of America, NT&SA nor Bank of America, FSB nor
any of their affiliates will have any obligations with respect to the Offered
Certificates except, in the case of the Sellers, for obligations arising from
certain representations and warranties of Bank of America, NT&SA and Bank of
America, FSB, acting through its division, BankAmerica Housing Services, with
respect to the Contracts sold by it in the Contract Pool and, in the case of
Bank of America, FSB, acting through its division, BankAmerica Housing Services,
for certain contractual servicing obligations, each as further described herein.
SUBJECT ONLY TO THE FOREGOING EXCEPTIONS, THE OFFERED CERTIFICATES WILL NOT
REPRESENT INTERESTS IN OR OBLIGATIONS OF BANK OF AMERICA NATIONAL TRUST AND
SAVINGS ASSOCIATION OR BANK OF AMERICA, FSB, THEIR PARENT CORPORATION,
BANKAMERICA CORPORATION, OR ANY AFFILIATE THEREOF, AND ASSETS IN THE TRUST FUND
WILL CONSTITUTE THE ONLY SOURCE OF FUNDS FOR PAYMENT ON THE OFFERED
CERTIFICATES. None of the Certificates will include the benefit of a guarantee
or limited guarantee of either Seller or an affiliate thereof. NONE OF THE
OFFERED CERTIFICATES NOR THE UNDERLYING CONTRACTS OR ANY COLLECTIONS THEREON
WILL BE INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR BY
ANY OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY.
 
    4. SUBORDINATION OF CLASS M AND CLASS B CERTIFICATES. The rights of the
holders of the Class M Certificates to receive distributions of available
amounts in the Trust Fund will be subordinate, to the extent described herein,
to the rights of the holders of the Senior Certificates. Consequently, if
shortfalls and/or losses arise with respect to the Certificates, they will be
borne by the Class M Certificateholders before they are borne by the Senior
Certificateholders. The rights of the holders of the Class B Certificates to
receive distributions of available amounts in the Trust Fund will be
subordinate, to the extent described
 
                                      S-15
<PAGE>
herein, to the rights of the holders of the Class M Certificates. Consequently,
if shortfalls and/or losses arise with respect to the Certificates, they will be
borne by the Class B Certificateholders before they are borne by the Class M
Certificateholders.
 
    5. PREPAYMENTS MAY AFFECT PASS-THROUGH RATES. The Pass-Through Rate for each
of the Certificates of Class A-7, Class A-8, Class M, Class B-1 and Class B-2 on
any Distribution Date will be adjusted so as not to exceed the weighted average
of the Net Contract Rates in the Contract Pool. Disproportionate prepayments
(including prepayments due to liquidations and repurchases by the Seller as
required or permitted by the Agreement) of Contracts with Net Contract Rates in
excess of the initial Pass-Through Rates (each an "Initial Pass-Through Rate")
for the Certificates will increase the possibility that the Pass-Through Rate
for such Classes of Certificates will be adjusted to an amount lower than the
related Initial Pass-Through Rate. There is no mechanism to compensate
Certificateholders for any such reduction. Any difference between interest at
the actual Pass-Through Rate and interest at the Initial Pass-Through Rate will
not constitute a shortfall, and any such difference will be foregone
permanently.
 
                              RECENT DEVELOPMENTS
 
    On April 11, 1998, BankAmerica Corporation ("BankAmerica"), the parent of
Bank of America, FSB, executed an agreement (the "Sale Agreement") with
GreenPoint Bank, a New York chartered savings bank, for the sale of the
operating business of the BankAmerica Housing Services division of Bank of
America, FSB to GreenPoint Credit Corporation ("GreenPoint Credit"), a wholly
owned subsidiary of GreenPoint Bank. Although there can be no assurance that the
conditions of the Sale Agreement will be satisfied and, thus, that the sale will
in fact be consummated, the parties to the Sale Agreement anticipate that a sale
of the division to GreenPoint Credit will occur by October 31, 1998.
 
    The administration and servicing functions of the Contracts and the
Manufactured Homes is performed by the BankAmerica Housing Services division by
personnel employed by it. Upon the consummation of the sale to GreenPoint
Credit, GreenPoint Credit will act as successor servicer under the Agreement.
Pursuant to the terms of the Agreement, all of the duties and rights of the
Servicer thereunder will automatically be assigned to GreenPoint Credit upon the
consummation of the sale of the Bank America Housing Services division and Bank
of America, FSB will be relieved of its obligations as Servicer under the
Agreement as long as such assignment would not result in a withdrawal or
downgrade of the then current rating or ratings of the Certificates. In the
event that the assignment would, in fact, result in such a withdrawal or a
downgrade, Bank of America, FSB will delegate its duties as Servicer to
GreenPoint Credit but would remain the Servicer of record under the Agreement,
and, therefore, primarily responsible for the servicing functions thereunder.
The Rating Agencies have preliminarily indicated that an assignment of the
servicing duties by Bank of America, FSB to GreenPoint Credit will not result in
a downgrade of the Certificates.
 
    Further, BankAmerica and NationsBank Corporation, a North Carolina
corporation ("NationsBank"), entered into an Agreement and Plan of
Reorganization on April 10, 1998 (the "Merger Agreement"). Pursuant to the
Merger Agreement, (i) NationsBank will form a new Delaware subsidiary
("NationsBank (DE)") and will merge (the "Reincorporation Merger") with and into
NationsBank (DE), with NationsBank (DE) as the surviving corporation in the
Reincorporation Merger and (ii) BankAmerica will thereafter merge (the "Merger,"
and together with the Reincorporation Merger, the "Reorganization") with and
into NationsBank (DE), with NationsBank (DE) as the surviving corporation in the
Merger. The Board of Directors of BankAmerica and the Board of Directors of
NationsBank approved the Reorganization and the transactions related thereto at
their meetings held April 9, 1998 and April 10, 1998, respectively. Consummation
of the Reorganization is subject to various conditions, including (i) approval
of the Merger Agreement and the Reorganization by the stockholders of each of
the parties thereto, and (ii) receipt of requisite approvals from the Board of
Governors of the Federal Reserve System and other federal and state regulatory
authorities as necessary. NationsBank is the parent of NationsBanc Montgomery
Securities LLC, a co-managing Underwriter of the Offered Certificates.

                               THE CONTRACT POOL
 
    Each Contract was originated or purchased by either Security Pacific
Financial Services of California, Inc. ("SPFSC"), a wholly owned subsidiary of
Bank of America, NT&SA, or by Bank of America, FSB, acting through its division,
BankAmerica Housing Services, in each case on an individual basis in the
ordinary course of its business. A description of Bank of America FSB's general
practices with respect to the origination or purchase of manufactured housing
contracts similar to the Contracts is set forth in the Prospectus under "The
Sellers--Loan Originations" and "The Sellers--Underwriting Policies."
 
    On the date of initial issuance of the Offered Certificates, each Seller
will convey to the Trust Fund the Contracts owned by it immediately prior to
such conveyance. The Contract Pool in the Trust Fund will consist of such
Contracts. Bank of America, FSB, acting through its division BankAmerica Housing
Services, as Servicer, will obtain and maintain possession of all Contract
documents. Upon the consumation of the transaction with GreenPoint Bank
described under "Recent Developments," GreenPoint Credit Corp., as Servicer,
will maintain possession of the Contracts.
 
    Approximately 94% of the Contracts (by outstanding principal balance as of
the Cut-off Date) will be sold by Bank of America, FSB, acting through its
division, BankAmerica Housing Services and approximately 6% will be sold by Bank
of America, NT&SA.
 
    The Contracts are all fixed rate actuarial Contracts. Some of the Contracts
in the Contract Pool are secured by a lien on real estate. None of the Contracts
(i) was purchased in bulk from an unrelated third party, (ii) is insured in
whole or in part or guaranteed in whole or in part, as applicable, by the
Veterans Administration, the Federal Housing Administration or by any other
governmental entity or instrumentality, (iii) is amortized using the "simple
interest" amortization method or (iv) has a variable Contract Rate or a Contract
Rate which steps up on particular dates.
 
    Management of Bank of America, FSB estimates that in excess of 85% of the
Manufactured Homes are used as primary residences by the Obligors under the
Contracts secured by such Manufactured Homes.
 
    As of the Cut-off Date, the Contract Rates on the Contracts ranged from
7.00% to 15.00%. The weighted average Contract Rate of the Contracts as of the
Cut-off Date was approximately 10.20%. As of the Cut-off Date, the Contracts had
remaining scheduled maturities of not more than 360 months, and original
scheduled maturities of at least 24 months but not more than 362 months. As of
the Cut-off Date, the Contracts had a weighted average remaining term to
maturity of approximately 232 months, and a weighted average original term to
scheduled maturity of approximately 258 months. The average outstanding
principal balance of the Contracts as of the Cut-off Date was approximately
$26,581 and the outstanding principal balances of the Contracts as of the
Cut-off Date ranged from approximately $439 to $145,467. The weighted average
loan-to-value ratio for the Contracts at origination was approximately 88.14%
and the loan-to-value ratio of the Contracts at origination ranged from 13.03%
to 95.46%. "Value" is equal to the total buyer's cost of the manufactured home
(including taxes, insurance and any prepaid finance charges or closing costs
that are financed). For Land Home and Land-in-Lieu Contracts, "Value" is equal
to (i) the value of the real property as determined by appraisal or tax
assessment, plus the total buyer's cost of the manufactured home (as indicated
above), plus the cost of the improvements to the land or (ii) in the case of a
manufactured home that is already located on the land, the final appraised value
of the land and manufactured home together. The underwriting practices of SPFSC
and the BankAmerica Housing Services division of Bank of America, FSB regarding
loan-to-value ratios of Contracts it originates or purchases are set forth in
the Prospectus under "The Sellers--Loan Originations" and "The
Sellers--Underwriting Policies." Manufactured homes, unlike site-built homes,
generally depreciate in value, and it has been the experience of the BankAmerica
Housing Services division of Bank of America, FSB that, upon repossession, the
market value of a manufactured home securing a manufactured housing contract is
generally lower than the principal balance of the related manufactured housing
contract. Certain statistical information relating to the average percentage of
principal recovered upon liquidation of certain manufactured housing contracts
is set forth herein and in the Prospectus under "The Sellers--
 
                                      S-17
<PAGE>
Delinquency and Loan Loss/Repossession Experience." Such statistical information
is included herein and therein only for illustrative purposes. There is no
assurance that the Contracts have characteristics that are similar to the
manufactured housing contracts to which such statistical information relates. In
addition, the percentage recovery of principal on liquidation of manufactured
housing contracts historically has been adversely affected by downturns in
regional or local economic conditions. These regional or local economic
conditions are often volatile, and no predictions can be made regarding future
economic loss upon liquidation. In light of the foregoing, no assurance can be
given that the percentage of principal recovered upon liquidation of defaulted
Contracts will be similar to any statistical information contained herein. See
"The Sellers-- Delinquency and Loan Loss/Repossession Experience" herein and in
the Prospectus.
 
    The Contracts are secured by Manufactured Homes located in 48 states and the
District of Columbia; approximately 9.10% of the Contracts by outstanding
principal balance as of the Cut-off Date were secured by Manufactured Homes
located in Texas, 8.74% in Georgia, 8.33% in Alabama, 7.05% in North Carolina,
5.49% in Florida and 5.33% in Tennessee. No other state represented more than 5%
(by outstanding principal balance as of the Cut-off Date) of the Contracts.
 
    Approximately 85% of the Contracts by outstanding principal balance as of
the Cut-off Date are secured by Manufactured Homes which were new at the time
the related Contracts were originated, and approximately 15% of the Contracts by
outstanding principal balance as of the Cut-off Date are secured by Manufactured
Homes which were used at the time the related Contracts were originated.
Approximately 11.36% of the Contracts by outstanding principal balance as of the
Cut-off Date are secured by liens on real estate as well as on Manufactured
Homes. See "Certain Legal Aspects of the Contracts" herein.

(1) Rounded to the nearest 1%. The definition of "Value" is set forth under "The
    Contract Pool" above. Manufactured Homes, unlike site-built homes, generally
    depreciate in value, and it should generally be expected, especially with
    Contracts with high loan-to-value ratios at origination, that at any time
    after the origination of a Contract, the market value of the Manufactured
    Home securing such Contract may be lower than the outstanding principal
    balance of such Contract.
 
(2) Entries may not add to 100.00% due to rounding.

BANK OF AMERICA, FSB'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF DELINQUENCY,
  REPOSSESSION AND LOAN LOSS EXPERIENCE
 
    The delinquency, repossession and loan loss experience exhibited by the
foregoing tables for the periods referenced therein are for illustrative
purposes only and there is no assurance that the delinquency, repossession or
loan loss experience of any Contracts sold to the Trust Fund will be similar to
that set forth above. Management believes the increase in the percentage net
losses in 1996 over 1995, for 1997 over 1996, and for the five month period
ended May 31, 1998 is due primarily to the seasoning of the portfolio.
Management believes that the rate of losses with respect to the contracts
serviced by it tend to increase during the first four years after origination,
and decrease thereafter, although there can be no assurance that such experience
will be reflected in the future. In light of the significant increase in the
number of contracts originated in each of 1995 and 1996 over each previous year,
the contracts originated after the end of 1994 may not have reached their
periods of peak potential for losses if the pattern described in the preceding
sentence were to continue. In general, the rate of losses has been higher for
contracts originated after 1994 than for contracts originated prior to such
period. In addition, the increase in losses in the five month period ended May
31, 1998 was also due to high levels of losses with respect to contracts
originated in 1995 and 1996. Management has not observed any material economic
development in the general business environment of the country or in local areas
where Bank of America, FSB, acting through its division, BankAmerica Housing
Services, originates its manufactured housing contracts, which has unfavorably
affected portfolio performance in relation to delinquencies, repossessions and
loan losses during
 
                                      S-27
<PAGE>
this period. However, the delinquency, loan loss and repossession experience of
manufactured housing contracts historically has been adversely affected by a
downturn in regional or local economic conditions. These regional or local
economic conditions are often volatile, and no predictions can be made regarding
future economic loss upon repossession. Information regarding the geographic
location, at origination, of the Manufactured Homes securing the Contracts in
the Contract Pool is set forth under "The Contract Pool" herein.
 
    Under certain limited circumstances, as set forth in the Agreement, the
Servicer may make a one-time modification to the Contract Rate with respect to
any Contract by an amount equal to the lesser of (i) 5% of such Contract Rate
and (ii) 0.50%.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
    The general prepayment and yield considerations discussed in the Prospectus
under "Prepayment and Yield Considerations" should be read carefully in
connection with a decision to invest in any of the Offered Certificates. The
following discussion supplements, and does not replace or supersede the
discussion under "Prepayment and Yield Considerations" in the Prospectus, unless
the context expressly so provides.
 
    The Contracts had maturities at origination ranging from 24 months to 362
months, but may be prepaid in full or in part at any time. The prepayment
experience of the Contracts (including prepayments due to liquidations of
defaulted Contracts) will affect the average life and the maturity of the
Offered Certificates. Bank of America, FSB does not maintain statistics with
respect to the rate of prepayment of manufactured housing contracts in its
servicing portfolio, except for contracts in certain pools of manufactured
housing contracts sold by SPHSI and contracts in certain pools of manufactured
housing contracts sold by Bank of America, FSB, Bank of America, NT&SA or SPFSC,
as the case may be, for which at least eighteen months of prepayment information
is available, as described in this Prospectus Supplement. Any pool of contracts,
including the Contract Pool, might include contracts with contract rates that
are generally higher or lower, in absolute terms or in comparison to prevailing
rates, than the contract rates of the contracts from which are derived certain
historical statistical data set forth below. As a result, the prepayment
experience of the contracts contained in any contract pool, including the
Contract Pool, might be faster or slower than the prepayment experience of the
contracts reflected in the historical data. In addition, although management of
the BankAmerica Housing Services division of Bank of America, FSB is aware of
limited publicly available information relating to historical rates of
prepayment on manufactured housing contracts, management of the BankAmerica
Housing Services division of Bank of America, FSB believes that such information
is not necessarily indicative of the rate of prepayment that may be expected to
be exhibited by the Contracts. Nevertheless, management of the BankAmerica
Housing Services division of Bank of America, FSB anticipates that a number of
Contracts will be prepaid in full in each year during which the Offered
Certificates are outstanding. See "Prepayment and Yield Considerations--
Prepayment Considerations," "Description of the Certificates--Optional and
Mandatory Repurchase; Optional Termination" and "Certain Legal Aspects of the
Contracts--Transfers of Manufactured Homes; Enforceability of Restrictions on
Transfer" in the Prospectus and "Description of the Certificates-- Optional
Termination and Termination Auction" herein for a discussion of certain factors
that may influence prepayments, including homeowner mobility, general and
regional economic conditions, prevailing interest rates, provisions in the
Contracts prohibiting the owner from selling the Manufactured Home without the
prior consent of the holder of the related Contract, the early termination of
the Trust Fund pursuant to a successful Termination Auction and the option of
the Servicer (whether or not Bank of America, FSB remains the Servicer) to
purchase the Contracts and any other property constituting the Trust Fund or to
direct the Trustee to solicit bids for an auction for the sale of the Contracts
and any other property constituting the Trust Fund. In addition, repurchases of
Contracts on account of certain breaches of representations and warranties as
described below under "Description of the Certificates--Conveyance
 
                                      S-28
<PAGE>
of Contracts" will have the effect of prepaying such Contracts and therefore
will affect the average life of the Certificates.
 
    The allocation of distributions to the Certificateholders in accordance with
the Agreement will have the effect of accelerating the amortization of certain
of the Classes of the Series 1998-2 Regular Certificates and delaying the
amortization of certain other Classes of the Series 1998-2 Regular Certificates
from the amortization that otherwise would be applicable if distributions in
respect of the Total Regular Principal Amount were made pro rata according to
the outstanding principal balances of the Series 1998-2 Regular Certificates. If
a purchaser of Offered Certificates in a Class of Offered Certificates purchases
them at a discount and calculates its anticipated yield to maturity based on an
assumed rate of distributions of principal on such Class of Offered Certificates
that is faster than the rate actually realized, such purchaser's actual yield to
maturity will be lower than the yield so calculated by such purchaser. See
"Description of the Certificates--Distributions" herein and "Prepayment and
Yield Considerations" in the Prospectus.
 
    There can be no assurance that the delinquency or repossession experience
set forth under "The Sellers--Delinquency and Loan Loss/Repossession Experience"
will be representative of the results that may be experienced with respect to
the Contracts. See "Prepayment and Yield Considerations" in the Prospectus for a
discussion of the effect delinquencies and repossessions on the Contracts would
have on the average life of the Certificates.
 
    The expected final scheduled payment date on the Contract with the latest
maturity is in May, 2028.
 
    The last scheduled Distribution Dates for the Series 1998-2 Regular
Certificates are set forth on the cover of this Prospectus Supplement. However,
the actual last Distribution Date for each such Class of Offered Certificates
could occur significantly earlier than such scheduled Distribution Dates. When
the Pool Scheduled Principal Balance falls below 10% of the Cut-off Date Pool
Principal Balance and certain other conditions are met, the Trust Fund could be
terminated pursuant to the Servicer's exercise of an option call or pursuant to
a successful Termination Auction. See "Description of the Certificates--
Optional Termination and Termination Auction" herein. Either of these events, if
they occur, would result in the early retirement of the then outstanding
Certificates.
 
    As described herein under "Description of the Certificates--Subordination"
and "Description of the Certificates--Losses on Liquidated Contracts," to the
extent that, on any Distribution Date, the Available Distribution Amount,
together with the Reserve Account Draw Amount, is not sufficient to permit a
full distribution of the Total Regular Principal Amount to the holders of any
Class of Offered Certificates, the effect will be to cause the Offered
Certificates to be amortized more slowly than they otherwise would have been
amortized, and losses on Liquidated Contracts and delinquencies on the Contracts
(if not covered by Monthly Advances) will be borne by the holders of such Class
of Offered Certificates in the manner described thereunder and as described
below.
 
    In the event there is a sufficiently large number of delinquencies on the
Contracts in any Collection Period that were not covered by Monthly Advances as
described herein, the amounts distributed to the holders of the Offered
Certificates could be less than the amount of principal and interest that
otherwise would be payable on such Certificates on the related Distribution
Date. In such event, even if delinquent payments on the Contracts were
eventually recovered upon liquidation, if the amounts received do not include
interest on delinquent interest payments, the effective yield on the Contracts
would be reduced, and under certain circumstances it is possible that sufficient
Available Distribution Amounts (together with the Reserve Account Draw Amount)
might not be available to provide for aggregate distributions on the Offered
Certificates equal to the sum of their initial outstanding Certificate Balances
plus accrued interest thereon, thereby reducing the effective yield on such
Certificates.
 
    Obligors are not required to pay interest on the Contracts after the date of
full prepayment of principal or the date of a partial prepayment of principal
(to the extent of such partial prepayment). As a
 
                                      S-29
<PAGE>
result, partial or full prepayments in advance of the related Due Dates for such
Contracts in any Collection Period will reduce the amount of interest received
from the related Obligors during such Collection Period to less than one month's
interest. However, when a partial prepayment is made on a Contract or a Contract
is prepaid in full during any Collection Period, but after the Due Date for such
Contract in such Collection Period, the effect will be to increase the amount of
interest received from the related Obligor during such Collection Period to more
than one month's interest. If a sufficient amount of partial prepayments are
made or a sufficient number of Contracts are prepaid in full in a given
Collection Period in advance of their respective Due Dates, interest received on
all of the Contracts during that Collection Period, after netting out the
Monthly Servicing Fee (and other expenses of the Trust Fund), may be less than
the interest payable on the Senior and/or Subordinate Certificates on the
related Distribution Date. As a result, the Available Distribution Amount
(together with the Reserve Account Draw Amount) for the related Distribution
Date may not be sufficient to distribute the interest on the Offered
Certificates in the full amount set forth herein under "Description of the
Certificates--Distributions" and to make a full distribution of the Total
Regular Principal Amount to the Senior Certificateholders and/or Subordinate
Certificateholders. Although no assurance can be given in this matter, Bank of
America, FSB does not anticipate that the net shortfall of interest caused by
partial prepayments or prepayments in full in any Collection Period would be
great enough, in the absence of delinquencies or liquidation losses, to reduce
the Available Distribution Amount for a Distribution Date below the amount that
would have been required to be distributed to the holders of the Offered
Certificates on that Distribution Date in the absence of such prepayment
interest shortfalls.
 
    Because the Contracts are actuarial Contracts, the outstanding principal
balances thereof will reduce, for purposes of accrual of interest thereon, by a
precomputed amortization amount on each Due Date whether or not the Scheduled
Payment for such Due Date is received in advance of or subsequent to such Due
Date, except as described above with respect to prepayments. See "The Contract
Pools" in the Prospectus. Thus, the effect of delinquent Scheduled Payments,
even if they are ultimately paid by the Obligor, will be to reduce the yields on
such Contracts below their respective Contract Rates (because interest will not
have accrued on the principal portion of any Scheduled Payment while it is
delinquent). If the Servicer does not make an advance with respect to such
delinquent Contracts as described herein, the result will be to reduce the
effective yield to the Trust Fund derived from such Contracts to a yield below
their Contract Rates. Under certain circumstances, such yield reductions could
cause the aggregate yield to the Trust Fund derived from the Contract Pool to be
insufficient to support the distribution of interest on the Offered
Certificates, after netting out other expenses of the Trust Fund.
 
    Certain statistical information relating to the prepayment behavior of
certain but not all pools of manufactured housing contracts sold by SPHSI, Bank
of America, NT&SA and Bank of America, FSB and serviced by SPHSI and now Bank of
America, FSB is set forth below in tabular form. The table relates to nineteen
sold pools for which prepayment information is available covering a period of at
least 18 months and which had an aggregate principal balance as of the first day
of the month of sale of at least $100,000,000. In evaluating whether the data
contained in the table contains useful information with respect to the expected
prepayment behavior of any particular contract pool, prospective
Certificateholders should consider the following neither Bank of America, FSB
nor SPHSI has performed statistical analysis to determine whether the contracts
to which the table relates constitutes a statistically significant sample of
manufactured housing contracts for purposes of determining expected prepayment
behavior. Furthermore, no assurance can be given that the Contracts in the
Contract Pool will have characteristics similar to the contracts in any sold
pool to which the following table relates. FOR THESE REASONS, AND BECAUSE OF THE
UNPREDICTABLE NATURE OF THE FACTORS DESCRIBED UNDER "--WEIGHTED AVERAGE LIFE OF
THE OFFERED CERTIFICATES" HEREIN, WHICH MAY INFLUENCE THE AMOUNT OF PREPAYMENTS
OF MANUFACTURED HOUSING CONTRACTS, NO ASSURANCE CAN BE GIVEN THAT THE PREPAYMENT
EXPERIENCE FOR THE CONTRACT POOL WITH AN AVERAGE AGE AS OF THE CUT-OFF DATE
SIMILAR TO THE AVERAGE AGES (AS OF THE FIRST DAY OF THE MONTH OF SALE) OF THE
POOLS TO WHICH THE TABLE RELATES WILL EXHIBIT PREPAYMENT BEHAVIOR SIMILAR TO THE
BEHAVIOR SUMMARIZED IN SUCH TABLE FOR THE PERIODS COVERED BY SUCH TABLE.
 
                                      S-30

    In addition to the foregoing, prospective Certificateholders should consider
that the table set forth below is limited in the periods which are covered
thereby and thus cannot reflect the effects, if any, of aging on the prepayment
behavior of manufactured housing contracts beyond the periods covered thereby.
 
    The table below sets forth with respect to certain pools of contracts (a)
the initial aggregate principal balance of the contracts in the pool (calculated
as of the first day of the month of the sale), (b) the weighted average contract
rate ("WAC") of the contracts in the pool as of the first day of the month of
the sale of such pool, (c) the weighted average remaining term to maturity
("WAM") of the contracts in the pool as of the first day of the month of the
sale of such pool, (d) the estimated average age of the pool as of the first day
of the month of the sale of such pool, (e) the aggregate principal balance of
such pool as of March 1, 1998, (f) the WAC of the contracts in the pool as of
March 1, 1998 and (g) the percentage of the Prepayment Model (as described in
"--Weighted Average Life of the Offered Certificates" below) for the life of
each pool through March 1, 1998. The prepayment performance of the contract
pools described in the following table is not indicative of the prepayment
performance of the Contracts in the Trust Fund, and no assurance can be given
that the prepayment performance of the Contracts in the Trust Fund will
correspond with the prepayment performance of any of the pools described below.

WEIGHTED AVERAGE LIFE OF THE OFFERED CERTIFICATES
 
    The following information is given solely to illustrate the effect of
prepayments of the Contracts on the weighted average life of the Offered
Certificates under the stated assumptions and is not a prediction of the
prepayment rate that might actually be experienced by the Contracts.
 
    Weighted average life refers to the average amount of time from the date of
issuance of a security until each dollar of principal of such security is repaid
to the investor. The weighted average life of an Offered Certificate is
determined by (i) multiplying the amount of each cash distribution in reduction
of the Certificate Balance of such Certificate by the number of years from the
date of issuance of such Certificate to the stated Distribution Date, (ii)
adding the results, and (iii) dividing the sum by the Initial Certificate
Balance of such Certificate. The weighted average life of the Offered
Certificates will be affected by the rate at which principal on the Contracts is
paid. Principal payments on Contracts may be in the form of scheduled
amortization or prepayments (for this purpose, the term "prepayment" includes
repayments (other than from scheduled amortization) and liquidations due to
default or other dispositions of Contracts). Prepayments on Contracts may be
measured by a prepayment standard or model. The model used in this Prospectus
Supplement ("Prepayment Model") is based on an assumed rate of prepayment each
month of the then unpaid principal balance of a pool of new contracts. 100% of
the Prepayment Model assumes prepayment rates of 3.7% per annum of the then
unpaid principal balance of such Contracts in the first month of the life of the
Contracts and an additional 0.1% per annum in each month thereafter (for
example, 3.9% per annum in the third month) until the 24th month. Beginning in
the 24th month and in each month thereafter during the life of the Contracts,
100% of the Prepayment Model assumes a constant prepayment rate of 6.0% per
annum.
 
    As used in the following table, "0% of the Prepayment Model" assumes no
prepayments on the Contracts; "100% of the Prepayment Model" assumes the
Contracts will prepay at rates equal to 100% of the Prepayment Model assumed
prepayment rates; "150% of the Prepayment Model" assumes the Contracts will
prepay at rates equal to 150% of the Prepayment Model assumed prepayment rates;
"170% of the Prepayment Model" assumes the Contracts will prepay at rates equal
to 170% of the Prepayment Model assumed prepayment rates; "200% of the
Prepayment Model" assumes the Contracts will prepay at rates equal to 200% of
the Prepayment Model assumed prepayment rates; "250% of the Prepayment Model"
assumes the Contracts will prepay at rates equal to 250% of the Prepayment Model
assumed prepayment rates; and "300% of the Prepayment Model" assumes the
Contracts will prepay at rates equal to 300% of the Prepayment Model assumed
prepayment rates.
 
    There is no assurance, however, that prepayments of the Contracts will
conform to any level of the Prepayment Model, and no representation is made that
the Contracts will prepay at the prepayment rates shown or any other prepayment
rate. The rate of principal payments on pools of manufactured housing contracts
is influenced by a variety of economic, geographic, social and other factors,
including the level of interest rates and the rate at which manufactured
homeowners sell their manufactured homes or default on their contracts. Other
factors affecting prepayment of such contracts include changes in obligors'
housing needs, job transfers, unemployment and obligors' net equity in the
manufactured homes. In the case of mortgage loans secured by site-built homes,
in general, if prevailing interest rates fall significantly below the interest
rates on such mortgage loans, the mortgage loans are likely to be subject to
higher prepayment rates than if prevailing interest rates remained at or above
the rates borne by such mortgage loans. Conversely, if prevailing interest rates
rise above the interest rates on such mortgage loans, the rate of prepayment
would be expected to decrease. In the case of manufactured housing contracts,
however, because the outstanding principal balances are, in general, smaller
than mortgage loan balances and the original term to maturity of each such
contract is generally shorter, the reduction or increase in the size of the
monthly payments on contracts of the same maturity and principal balance arising
from a change in the interest rate thereon is generally smaller. Consequently,
changes in prevailing interest rates may not have a similar effect, or may have
a similar effect, but to a smaller degree, on the prepayment rates on
manufactured housing contracts.

Contracts, as of the Cut-off Date, will be grouped into [nineteen] groups having
the additional characteristics set forth in the table entitled "Assumed Contract
Characteristics" below, (iv) the Class A-1 Certificates initially represent
6.97% of the entire ownership interest in the Trust Fund and have a Class A-1
Pass-Through Rate of [   ]% per annum, the Class A-2 Certificates initially
represent 11.52% of the entire ownership interest in the Trust Fund and have a
Class A-2 Pass-Through Rate of [      ]% per annum, the Class A-3 Certificates
initially represent 9.33% of the entire ownership interest in the Trust Fund and
have a Class A-3 Pass-Through Rate of [      ]% per annum, the Class A-4
Certificates initially represent 11.37% of the entire ownership interest in the
Trust Fund and have a Class A-4 Pass-Through Rate of [      ]% per annum, the
Class A-5 Certificates initially represent 6.41% of the entire ownership
interest in the Trust Fund and have a Class A-5 Pass-Through Rate of [      ]%
per annum, the Class A-6 Certificates initially represent 10.06% of the entire
ownership interest in the Trust Fund and have a Class A-6 Pass-Through Rate of
[      ]% per annum, the Class A-7 Certificates initially represent 16.91% of
the entire ownership interest in the Trust Fund and have a Class A-7
Pass-Through Rate of [      ]% per annum, the Class A-8 Certificates initially
represent 9.43% of the entire ownership interest in the Trust Fund and have a
Class A-8 Pass-Through Rate of [      ]% per annum, the Class M Certificates
initially represent 7.50% of the entire ownership interest in the Trust Fund and
have a Class M Pass-Through Rate of [      ]% per annum and the Class B-1
Certificates initially represent 6.00% of the entire ownership interest in the
Trust Fund and have a Class B-1 Pass-Through Rate of [      ]% per annum, (v) no
interest shortfalls will arise in connection with prepayment in full of the
Contracts, (vi) there will be no repurchases of any Contracts due to a breach in
a representation or warranty with respect thereto, and (vii) a servicing fee of
1.00% per annum will be paid to the Servicer. The tables assume that there are
no losses or delinquencies on the Contracts. No representation is made that
losses or delinquencies on the Contracts will be experienced at the rate assumed
in the preceding sentence or at any other rate.

    Since the tables were prepared on the basis of the Structuring Assumptions
in the preceding paragraph, there are discrepancies between the characteristics
of the actual Contracts and the characteristics of the Contracts assumed in
preparing the tables. Any such discrepancy may have an effect upon the
percentages of the Initial Certificate Balance of each Class of Offered
Certificates outstanding and weighted average lives of such Certificates set
forth in the tables. In addition, since the actual Contracts and the Trust Fund
have characteristics which differ from those assumed in preparing the tables set
forth below, the distributions of principal on the Offered Certificates may be
made earlier or later than as indicated in the tables.
 
    It is not likely that Contracts will prepay at any constant percentage of
the Prepayment Model to maturity or that all Contracts will prepay at the same
rate. In addition, the diverse remaining terms to maturity of the Contracts
(which include recently originated Contracts) could produce slower distributions
of principal than indicated in the tables at the various percentages of the
Prepayment Model specified even if the weighted average remaining term to
maturity of the Contracts is 232 months.
 
    Investors are urged to make their investment decisions on a basis that
includes their determination as to anticipated prepayment rates under a variety
of the assumptions discussed herein.

FINAL SCHEDULED DISTRIBUTION DATE
 
    The Final Scheduled Distribution Dates for each Class of Offered
Certificates is set forth on the cover hereof. The Final Scheduled Distribution
Dates for the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6,
Class A-7, Class A-8, Class M and Class B-1 Certificates were determined on the
basis of the Structuring Assumptions and the assumption that there are no
prepayments, the Servicer does not exercise its optional termination right and
the Contracts are not sold in a Termination Auction. The actual final
Distribution Date for each Class of Offered Certificates is likely to be
shorter, and could occur significantly earlier than, the applicable Final
Scheduled Distribution Date because (i) prepayments are likely to occur, (ii)
the Sellers may repurchase Contracts in the event of breaches of representations
and warranties and (iii) the Servicer may cause an optional termination of the
Trust Fund or a Termination Auction may occur.

<PAGE>
                        DESCRIPTION OF THE CERTIFICATES
 
    The Certificates will be issued pursuant to the Pooling and Servicing
Agreement (the "Agreement"). A form of the Pooling and Servicing Agreement will
be made available to prospective investors upon request (made to the Servicer at
the address specified in the Prospectus under "Incorporation of Certain
Documents by Reference") and will be filed with the Securities and Exchange
Commission after the initial issuance of the Certificates as an exhibit to a
Current Report on Form 8-K. Reference is made to the Prospectus for additional
information regarding the terms and conditions of the Agreement. The following
discussion supplements, and does not replace or supersede the discussion under
"Description of the Certificates" in the Prospectus, unless the context
otherwise provides.
 
    Set forth below are summaries of the specific terms and provisions pursuant
to which the Certificates will be issued. The following summaries do not purport
to be complete and are subject to, and are qualified in their entirety by
reference to, the provisions of the Agreement. When particular provisions or
terms used in the Agreement are referred to, the actual provisions (including
definitions of terms) are incorporated by reference.
 
GENERAL
 
    The Offered Certificates will be issued in fully registered form only, in
denominations equal to $1,000 or any integral multiple of one dollar in excess
thereof. The "Percentage Interest" of a Certificate of a Class (other than a
Class R Certificate) is the percentage obtained from dividing the original
denomination of such Certificate by the Initial Certificate Balance of the
Certificates of such Class.
 
    The Trust Fund includes (i) the Contract Pool, including certain rights to
receive payments on the Contracts on and after the Cut-off Date, (ii) the
amounts held from time to time in the "Certificate Account" (as described below
under "--Payment on Contracts; Certificate Account") maintained by the Trustee
pursuant to the Agreement, (iii) any property which initially secured a Contract
and which is acquired in the process of realizing thereon, (iv) the obligations
of Bank of America, NT&SA and Bank of America, FSB, under certain conditions, to
repurchase Contracts sold by it with respect to which certain representations
and warranties have been breached and not cured, (v) the proceeds of all
insurance policies described herein and (vi) the Reserve Account.
 
    Bank of America, NT&SA and Bank of America, FSB, will convey the Contracts
to the Trustee. See "The Contract Pool" herein and "--Conveyance of Contracts"
below. Bank of America, FSB, acting through its division, BankAmerica Housing
Services, as Servicer, will service the Contracts pursuant to the Agreement. The
Contract documents will be held for the benefit of the Trustee by the Servicer.
 
    Distributions of principal and interest to the holders of the Certificates
will be made on the 10th day of each month, or, if such day is not a business
day, the next succeeding business day (each, a "Distribution Date") beginning in
July, 1998, to the persons in whose names the Certificates are registered at the
close of business on the last business day preceding each Distribution Date (the
"Record Date").
 
    If there is a single investor for the Class A-5, Class A-6, Class A-7 and
Class A-8 Certificates, and such investor so elects, such classes will be
consolidated into the Class A-5 Certificates with one Pass-Through Rate and will
have an initial Certificate Balance of $293,705,000. If such classes are
consolidated, references to the Class A-5, Class A-6, Class A-7 and Class A-8
Certificates shall generally by deemed to mean the Class A-5 Certificates.
 
                                      S-45
<PAGE>
PASS-THROUGH RATES
 
    Interest on each Class of Certificates will be computed on the basis of a
360-day year of twelve 30-day months.
 
    The Class A-1 Pass-Through Rate will be [      ]% per annum.
 
    The Class A-2 Pass-Through Rate will be [      ]% per annum.
 
    The Class A-3 Pass-Through Rate will be [      ]% per annum.
 
    The Class A-4 Pass-Through Rate will be [      ]% per annum.
 
    The Class A-5 Pass-Through Rate will be [      ]% per annum.
 
    The Class A-6 Pass-Through Rate will be [      ]% per annum.
 
    The Class A-7 Pass-Through Rate will be the lesser of [      ]% per annum
and the Weighted Average Net Contract Rate.
 
    The Class A-8 Pass-Through Rate will be the lesser of [      ]% per annum
and the Weighted Average Net Contract Rate.
 
    The Class M Pass-Through Rate will be the lesser of [      ]% per annum and
the Weighted Average Net Contract Rate.
 
    The Class B-1 Pass-Through Rate will be the lesser of [      ]% per annum
and the Weighted Average Net Contract Rate.
 
    The Class B-2 Pass-Through Rate will be the lesser of [      ]% per annum
and the Weighted Average Net Contract Rate.
 
    The "Weighted Average Net Contract Rate" is equal to the weighted average of
the Net Contract Rates of the Contracts in the Contract Pool at the beginning of
the month preceding the month of such Distribution Date. The "Net Contract Rate"
of a Contract equals the rate of interest borne by such Contract minus the
Annual Servicing Rate. The "Annual Servicing Rate" is equal to 1.00%. The
Weighted Average Net Contract Rate as of the Cut-off Date was approximately
9.20%.
 
    In all but the most unusual prepayment scenarios, it is anticipated that the
Weighted Average Net Contract Rate will equal or exceed the specific percentages
set forth above. If a large principal amount of Contracts having Contract Rates
higher than [      ]% were to prepay while a proportionate principal amount of
the Contracts having Contract Rates lower than [      ]% did not prepay, the
interest collections on the remaining Contracts would not be sufficient to
support the specific percentages set forth above for the Class A-7, Class A-8,
Class M, Class B-1 and Class B-2 Certificates. Of the initial Contracts,
[      ]% by aggregate principal balance as of the Cut-off Date had Contract
Rates equal to or higher than [      ]%.
 
CONVEYANCE OF CONTRACTS
 
    On the date of initial issuance of the Certificates, Bank of America, NT&SA
and Bank of America, FSB will convey to the Trustee, without recourse, all
right, title and interest of Bank of America, NT&SA and Bank of America, FSB,
respectively, in and to the Contracts, and all rights under the standard hazard
insurance policies on the related Manufactured Homes. The conveyance of the
Contracts to the Trustee will include a conveyance of all rights to receive
Scheduled Payments thereon that were due on or after the Cut-off Date, even if
received prior to the Cut-off Date, as well as all rights to any payments
received on or after the Cut-off Date (other than late receipts of Scheduled
Payments that were due prior to the Cut-off Date). The Contracts will be
described on a schedule attached to the Agreement (the "Contract Schedule"). The
Contract Schedule will include the principal balance of each Contract as of the
Cut-off
 
                                      S-46
<PAGE>
Date, the amount of each Scheduled Payment due on each Contract as of the
Cut-off Date, the Contract Rate on each Contract (determined as of the Cut-off
Date) and the maturity date of each Contract. Prior to the conveyance of the
Contracts to the Trustee, the operations department of the BankAmerica Housing
Services division of Bank of America, FSB will be required to complete a review
of all of the originals of the Contracts, the certificates of title to, or other
evidence of a perfected security interest in, the Manufactured Homes, any
related mortgages and any assignments or modifications of the foregoing
(collectively, the "Contract Files") confirming the accuracy of the Contract
Schedule delivered to the Trustee. Any Contract discovered not to agree with
such schedule in a manner that is materially adverse to the interests of the
Certificateholders will be repurchased by Bank of America, NT&SA and Bank of
America, FSB, as applicable, or replaced with another Contract, except that if
the discrepancy relates to the principal balance of a Contract (determined as
described above), Bank of America, NT&SA and Bank of America, FSB, as
applicable, may, under certain conditions, deposit cash in the Certificate
Account in an amount sufficient to offset such discrepancy. The Trustee will not
review the Contract Files.
 
    The Servicer will hold, as custodian and agent on behalf of the Trustee, the
original Contracts and copies of documents and instruments relating to each
Contract and the security interest in the Manufactured Home, and real property,
if any, relating to each Contract. See "Risk Factors--Security Interests in the
Manufactured Homes; Transfer of Contracts and Security Interests" and "Certain
Legal Aspects of the Contracts--Security Interests in Manufactured Homes" and
"--Land Home and Land-in-Lieu Contracts" in the Prospectus for discussion of the
consequences of the Servicer maintaining possession of the original Contracts
and the security interest in the related Manufactured Homes and real property,
if any, securing such Contracts. In order to give notice of the Trustee's right,
title and interest in and to the Contracts, a UCC-1 financing statement
identifying the Trustee as the secured party and identifying all the Contracts
as collateral will be filed in the appropriate office in the appropriate states.
The Contracts will be stamped or otherwise marked to reflect their assignment to
the Trustee. To the extent that the Contracts do not constitute "chattel paper"
within the meaning of the UCC as in effect in the applicable jurisdictions or to
the extent that the Contracts do constitute chattel paper and a subsequent
purchaser is able to take physical possession of the Contracts without notice of
such assignment, the Trustee's interest in the Contracts could be defeated. See
"Certain Legal Aspects of the Contracts" in the Prospectus.

                                      S-47
<PAGE>
after such assignment, the Trustee has a valid and perfected first-priority
security interest in the Manufactured Home and real property, if any, securing
such Contract, (l) such Contract has not been sold, assigned or pledged to any
other person, and prior to the transfer of the Contracts to the Trustee, Bank of
America, NT&SA or Bank of America, FSB, as the case may be, had good and

permitted by clause (a) above), and Bank of America, NT&SA or Bank of America,
FSB, as the case may be, has not waived any of the foregoing; (n) as of the
Closing Date (as defined below), there were, to the knowledge of Bank of
America, NT&SA or Bank of America, FSB, as applicable, no liens or claims which

Contract with the lowest Contract Rate has a Contract Rate of 7.00% and the
Contract with the highest Contract Rate has a Contract Rate of 15.00%. Under the
terms of the Agreement, and subject to the relevant Seller's option to effect a
substitution with respect to Contracts sold by it as described in the last
paragraph under this subheading, Bank of America, NT&SA or Bank of America, FSB,
as the case may be, will be obligated to repurchase, at the price described
below, any Contract sold by it within 90 days after Bank of America, NT&SA or
Bank of America, FSB, as the case may be, becomes aware, or after Bank of
America, NT&SA or Bank of America, FSB's receipt of written notice from the
Trustee or the Servicer, of a breach of any representation or warranty of Bank
of America, NT&SA or Bank of America, FSB, as the case may be, in the Agreement
that materially and adversely affects the Trust Fund's interest in any Contract
it sold thereto unless such breach has been cured.
 
    Notwithstanding the foregoing, neither Bank of America, NT&SA nor Bank of
America, FSB will be required to repurchase or substitute any Contract relating
to a Manufactured Home and real property, if any, securing such Contract located
in any jurisdiction on account of a breach of the representation and warranty
described in clause (k) above solely on the basis of the failure by Bank of
America, NT&SA or Bank of America, FSB, as applicable, to cause a notation to be
made on any document of title relating to any such Manufactured Home or to
execute any transfer instrument relating to any such Manufactured Home or real
property, if any (other than a notation or transfer instrument necessary to show
Bank of America, NT&SA or Bank of America, FSB as lienholder or legal title
holder) unless (i) a court of competent jurisdiction has adjudged that, because
of such failure, the Trustee does not have a perfected first-priority security
interest in such related Manufactured Home or (ii)(A) the Servicer has received
 
                                      S-48
<PAGE>
written advice of counsel to the effect that a court of competent jurisdiction
has held that, solely because of a substantially similar failure on the part of
a pledgor or assignor of manufactured housing contracts (who has perfected the
assignment or pledge of such contracts), a perfected first-priority security
interest was not created in favor of the pledgee or assignee in a related
manufactured home which is located in such jurisdiction and which is subject to
the same laws regarding the perfection of security interests therein applicable
to the Manufactured Homes located in such jurisdiction and (B) the Servicer
shall not have completed all appropriate remedial action with respect to such
Manufactured Home within 180 days after receipt of such written advice. Any such
advice will be from counsel selected by the Servicer on a non-discriminatory
basis from among the counsel used by the Servicer in its general business in the
jurisdiction in question. The Servicer will have no ongoing obligation to seek
advice with respect to the matters described in clause (ii) above. However, the
Servicer is required to seek advice with respect to such matters whenever
information comes to the attention of its counsel which causes such counsel to
determine that a holding of the type described in clause (ii)(A) might exist. If
any counsel selected by the Servicer informs the Servicer that no holding of the
type described in clause (ii)(A) exists, such advice will be conclusive and
binding on the parties to the Agreement pursuant to which a Trustee has an
interest in any Contracts in the applicable jurisdiction as of the applicable
date. If any holding described above which would give rise to a repurchase
obligation on the part of Bank of America, NT&SA or Bank of America, FSB, as
applicable, were to result from proceedings brought by a receiver or conservator
of Bank of America, NT&SA or Bank of America, FSB, it is likely that such
receiver or conservator would also reject the resulting repurchase obligation.
 
    The repurchase obligation described above generally constitutes the sole
remedy available to the Trustee and the Certificateholders for a breach of a
representation or warranty under the Agreement with respect to the Contracts.
The repurchase price for any Contract will be equal to the remaining principal
balance of such Contract as of the beginning of the month of repurchase, plus
accrued and unpaid interest from the Due Date with respect to which the Obligor
last made a payment to the Due Date occurring in the Collection Period during
which such Contract is repurchased.
 
    In lieu of repurchasing a Contract as specified above, during the two-year
period following the date of the initial issuance of the Certificates (the
"Closing Date"), Bank of America, FSB or, where applicable, Bank of America,
NT&SA, may, at its option, substitute an Eligible Substitute Contract (as
defined below) for the Contract that it is otherwise obligated to repurchase
(referred to herein as the "Replaced Contract"). An "Eligible Substitute
Contract" is a Contract that satisfies, as of the date of its substitution, the
representations and warranties specified in the Agreement, has a Scheduled
Principal Balance that is not greater than the Scheduled Principal Balance of
the Replaced Contract as of the beginning of the month in which such
substitution takes place, has a Contract Rate that is at least equal to the
Contract Rate of the Replaced Contract, has a remaining term to scheduled
maturity that is not greater than the remaining term to scheduled maturity of
the Replaced Contract and has not been delinquent for more than 31 days as to
any Scheduled Payment due in the twelve months prior to its substitution. Bank
of America, NT&SA or Bank of America, FSB, as applicable, will be required to
deposit in the Certificate Account cash in the amount, if any, by which the
Scheduled Principal Balance of the Replaced Contract as of the beginning of the
month in which substitution takes place exceeds the Scheduled Principal Balance
of the Contract it sold being substituted as of the beginning of the month.
 
PAYMENTS ON THE CONTRACTS; CERTIFICATE ACCOUNT
 
    The Trustee will initially establish and maintain an account (the
"Certificate Account") at a depository institution organized under the laws of
the United States or any state, the deposits of which are insured to the full
extent permitted by law by the Federal Deposit Insurance Corporation (the
"FDIC") whose commercial paper, long-term deposits or long-term unsecured senior
debt has a rating of P-1 by Moody's and F-1 by Fitch (if rated by Fitch) in the
case of commercial paper or in one of the two highest rating categories by
Moody's and Fitch (if rated by Fitch) in the case of long-term deposits or
long-term
 
                                      S-49
<PAGE>
unsecured senior debt, and which is subject to examination by federal or state
authorities or a depository institution otherwise acceptable to Moody's and
Fitch (an "Eligible Institution"). The funds in the Certificate Account are
required to be invested by the Trustee in common trust funds, collective
investment trusts or Eligible Investments that will mature not later than the
business day preceding the applicable Distribution Date. "Eligible Investments"
include, among other investments, obligations of the United States or of any
agency thereof backed by the full faith and credit of the United States;
certificates of deposit, time deposits and bankers' acceptances sold by eligible
financial institutions; commercial paper rated P-1 by Moody's and F-1 by Fitch
(if rated by Fitch); money market funds acceptable to Moody's and Fitch (as
evidenced by a letter from Moody's and Fitch to such effect); and other
obligations acceptable to Moody's and Fitch.
 
    All payments in respect of principal and interest on the Contracts received
during any Collection Period by the Servicer (exclusive of Scheduled Payments
due prior to the Cut-off Date), including Liquidation Proceeds (net of
Liquidation Expenses, as defined below), are required to be paid into the
Certificate Account not later than the second business day following receipt
thereof. Amounts received as late payment fees, extension fees, assumption fees
or similar fees may be retained by the Servicer as part of its servicing fees.
See "--Servicing Compensation; Certain Other Matters Regarding the Servicer"
below. In addition, the amount paid by Bank of America, NT&SA or Bank of
America, FSB, as applicable, for any Contract repurchased by it as a result of a
breach of a representation or warranty under the Agreement, and amounts required
to be deposited upon substitution of an Eligible Substitute Contract because of
a breach of a representation or warranty (which amounts will be treated as
partial principal prepayments), as described under "--Conveyance of Contracts"
above, are required to be paid into the Certificate Account.
 
    On the third business day prior to each Distribution Date (the
"Determination Date"), the Servicer will determine the Available Distribution
Amount and the amounts to be distributed on the Certificates on such
Distribution Date. The "Available Distribution Amount" for any Distribution Date
is the sum of (a) the Monthly Advance for such Distribution Date (as defined
below under "--Advances") and (b) the amount in the Certificate Account on the
close of business on the last day of the immediately preceding Collection
Period, less the sum of (i) any repossession profits (of which there are
expected to be a DE MINIMIS amount) on defaulted Contracts, (ii) payments on
Contracts that have been repurchased as a result of a breach of a representation
or warranty that are received during or after the month of repurchase, (iii)
Excess Contract Payments (as defined below) and any other payments not required
to be distributed to Certificateholders on the related Distribution Date, (iv)
reimbursements to the Servicer in the amount of expenses incurred in connection
with the liquidation of a Contract ("Liquidation Expenses") and certain taxes
and insurance premiums advanced by the Servicer in respect of Manufactured Homes
(as described below under "--Advances"), (v) reimbursements to the Servicer for
Nonrecoverable Advances in respect of Contracts and Monthly Advances to the
extent permitted by the Agreement (as described below under "--Advances") and
(vi) the Monthly Servicing Fee (as hereinafter defined).
 
    An "Excess Contract Payment" is a payment received on a Contract that is in
excess of the Scheduled Payment (or, generally, an integral multiple thereof) on
such Contract, is not a partial principal prepayment or prepayment in full and
is not part of any Liquidation Proceeds. Excess Contract Payments will be held
by the Trustee in the Certificate Account and may be applied as described under
"--Advances" below.
 
    The Trustee or its paying agent will withdraw funds from the Certificate
Account on each Distribution Date (but only to the extent of the related
Available Distribution Amount) to make payments to Certificateholders as
specified under "--Distributions" below. From time to time, as provided in the
Agreement, the Servicer will also withdraw funds from the Certificate Account to
make payments to Bank of America, NT&SA or Bank of America, FSB as permitted by
the Agreement and described in subclauses (i), (ii), (iv), (v) and (vi) of
clause (b) in the second preceding paragraph.

DISTRIBUTIONS
 
    Distributions to the holders of the Series 1998-2 Regular Certificates will
be applied first to the holders of the Senior Certificates, second to the
holders of the Class M Certificates and third to the holders of the Class B
Certificates. The Available Distribution Amount for each Distribution Date will
be applied in the amounts and the order of priority set forth below.
Distributions to holders of each Class of Certificates of principal and interest
will be made on each Distribution Date in an amount equal to their respective
Percentage Interests multiplied by the aggregate amount distributed to such
Class of Certificates on such Distribution Date.
 
    No payments of principal will be made to the holders of the Class M
Certificates until the Senior Certificate Balance has been reduced to zero, no
payments of principal will be made to the holders of the Class B-1 Certificates
until the Class M Certificate Balance has been reduced to zero and no payments
of principal will be made to the holders of the Class B-2 Certificates until the
Class B-1 Certificate Balance has been reduced to zero.
 
    Each distribution with respect to book-entry certificates will be paid to
DTC, which will credit the amount of such distribution to the accounts of its
participants in accordance with its normal procedures. Each participant will be
responsible for disbursing such distribution to the Certificate Owners that it
represents and to each indirect participating brokerage firm (a "brokerage firm"
or "indirect participating firm") for which it acts as agent. Each brokerage
firm will be responsible for disbursing funds to the Certificate Owners that it
represents. All such credits and disbursements with respect to book-entry
certificates are to be made by DTC and its participants in accordance with DTC's
rules. See "Description of the Certificates--Global Certificates" below.
 
    PRIORITIES.  On each Distribution Date, the Available Distribution Amount,
together with the Reserve Account Draw Amount (as defined herein), if any, will
be distributed in the following amounts and in the following order of priority:
 
        (i) concurrently to the Class A-1, Class A-2, Class A-3, Class A-4,
    Class A-5, Class A-6, Class A-7 and Class A-8 Certificateholders, the Class
    A-1 Interest Distribution Amount, the Class A-2 Interest Distribution
    Amount, the Class A-3 Interest Distribution Amount, the Class A-4 Interest
    Distribution Amount, the Class A-5 Interest Distribution Amount, the Class
    A-6 Interest Distribution Amount, the Class A-7 Interest Distribution Amount
    and the Class A-8 Interest Distribution Amount, respectively;
 
        (ii) to the Senior Certificateholders, the Formula Principal
    Distribution Amount in the following order of priority:
 
           (a) to the Class A-1 Certificateholders until the Certificate Balance
       of the Class A-1 Certificates is reduced to zero;
 
           (b) to the Class A-2 Certificateholders until the Certificate Balance
       of the Class A-2 Certificates is reduced to zero;
 
           (c) to the Class A-3 Certificateholders until the Certificate Balance
       of the Class A-3 Certificates is reduced to zero;
 
           (d) to the Class A-4 Certificateholders until the Certificate Balance
       of the Class A-4 Certificates is reduced to zero;
 
           (e) to the Class A-5 Certificateholders until the Certificate Balance
       of the Class A-5 Certificates is reduced to zero;
 
           (f) to the Class A-6 Certificateholders until the Certificate Balance
       of the Class A-6 Certificates is reduced to zero;
 
                                      S-51
<PAGE>
           (g) to the Class A-7 Certificateholders until the Certificate Balance
       of the Class A-7 Certificates is reduced to zero; and
 
           (h) to the Class A-8 Certificateholders until the Certificate Balance
       of the Class A-8 Certificates is reduced to zero;
 
       (iii) to the Class M Certificateholders, the Class M Interest
    Distribution Amount;
 
        (iv) to the Class M Certificateholders, the Formula Principal
    Distribution Amount until the Class M Certificate Balance is reduced to
    zero;
 
        (v) to the Class B-1 Certificateholders, the Class B-1 Interest
    Distribution Amount;
 
        (vi) to the Class B-1 Certificateholders, the Formula Principal
    Distribution Amount until the Class B-1 Certificate Balance is reduced to
    zero;
 
       (vii) to the Class B-2 Certificateholders, the Class B-2 Interest
    Distribution Amount;
 
      (viii) to the Class B-2 Certificateholders, the Formula Principal
    Distribution Amount until the Class B-2 Certificate Balance is reduced to
    zero;
 
        (ix) to the Reserve Account, any remaining Available Distribution Amount
    until the amount on deposit therein equals the Reserve Account Cap; and
 
        (x) to the Class R Certificateholders, any remaining Available
    Distribution Amount.
 
    In addition, notwithstanding the prioritization of the distribution of the
Formula Principal Distribution Amount to the holders of the Senior Certificates
pursuant to clause (ii) above, on a Distribution Date, if any, in respect of
which a Deficiency Event (defined below) is in effect, the portion of the
Formula Principal Distribution Amount for such Distribution Date that would
otherwise be distributed sequentially to the holders of the Senior Certificates
pursuant to clause (ii) above will instead be distributed to the holders of the
Senior Certificates PRO RATA based upon the Certificate Balance of each such
Class until the Certificate Balances of each of the Senior Certificates have
been reduced to zero. A "Deficiency Event" will be in effect for any
Distribution Date as to which the Pool Scheduled Principal Balance is equal to
or less than the aggregate Certificate Balance of the Senior Certificates.
 
    Furthermore, notwithstanding the foregoing, if the Formula Principal
Distribution Amount allocable to the holders of the Class A-8 Certificates on
any Distribution Date pursuant to clause (ii) above exceeds the Class A-8
Certificate Balance for such Distribution Date, such excess will be distributed
to the Class M Certificateholders. If the Formula Principal Distribution Amount
allocable to the Class M Certificateholders on any Distribution Date pursuant to
clause (iv) above exceeds the Class M Certificate Balance for any such
Distribution Date, such excess will be distributed to the Class B-1
Certificateholders until the Class B-1 Certificate Balance is reduced to zero
(and to the Class B-2 Certificateholders thereafter).
 
    DEFINITIONS.  Except as described below, as to any Distribution Date, the
"Interest Distribution Amount" for any Class is equal to the sum of (i) one
month's interest at the Pass-Through Rate for that Class on the Certificate
Balance of that Class and (ii) any previously undistributed shortfalls in
interest due to the Certificateholders of that Class in respect of prior
Distribution Dates. Any shortfall in interest due to Certificateholders will, to
the extent legally permissible, bear interest at the related Pass-Through Rate.
Interest will accrue with respect to each Distribution Date in respect of the
Series 1998-2 Regular Certificates during the one-month period beginning on the
10th day of the month preceding the month of such Distribution Date and ending
on the 9th day of the month of such Distribution Date (each, an "Interest
Accrual Period).
 
    The "Formula Principal Distribution Amount" in respect of a Distribution
Date equals the sum of (a) the Total Regular Principal Amount for such
Distribution Date and (b) any previously undistributed shortfalls in the
distribution of the Total Regular Principal Amount in respect of prior
Distribution Dates.
 
                                      S-52
<PAGE>
    The "Total Regular Principal Amount" on each Distribution Date is the sum of
(i) the Scheduled Principal Reduction Amount (defined below) for such
Distribution Date, (ii) the Scheduled Principal Balance (defined below) of each
Contract which, during the related Collection Period, was purchased by Bank of
America, NT&SA or Bank of America, FSB, as the case may be, on account of
certain breaches of representations and warranties made by it in the Agreement,
(iii) all partial prepayments received during such related Collection Period,
(iv) the Scheduled Principal Balance of each Contract that was prepaid in full
during such related Collection Period and (v) the Scheduled Principal Balance of
each Contract that became a Liquidated Contract (defined below) during such
related Collection Period.
 
    The "Scheduled Principal Balance" of a Contract for any Distribution Date is
its principal balance as of the Due Date in the Collection Period immediately
preceding such Distribution Date, after giving effect to all previous partial
prepayments, all previous scheduled principal payments (whether or not paid) and
the scheduled principal payment due on such Due Date, but without giving effect
to any adjustment due to bankruptcy or similar proceedings. The "Scheduled
Principal Reduction Amount" for any Distribution Date is an approximate
calculation (performed on an aggregate basis rather than on a Contract-by-
Contract basis) of the scheduled payments of principal due during the related
Collection Period. Both of these terms are more fully described herein under
"--Distributions" above.
 
    The "Pool Scheduled Principal Balance" for any Distribution Date is equal to
the Cut-off Date Pool Principal Balance less the aggregate of the Total Regular
Principal Amounts for all prior Distribution Dates.
 
    In general, a "Liquidated Contract" is a defaulted Contract as to which all
amounts that the Servicer expects to recover relating to such Contract
("Liquidation Proceeds") have been received. A Liquidated Contract includes any
defaulted Contract in respect of which the related Manufactured Home has been
realized upon and disposed of and the proceeds of such disposition have been
received.
 
    The "Certificate Balance" for any Class as of any Distribution Date is the
Initial Certificate Balance of that Class less all amounts previously
distributed to Certificateholders of that Class on account of principal. The
"Senior Certificate Balance" as of any Distribution Date is the sum of the
Certificate Balances of the Senior Certificates immediately prior to such
Distribution Date. The "Subordinate Certificate Balance" as of any Distribution
Date is the sum of the Class M Certificate Balance, the Class B-1 Certificate
Balance and the Class B-2 Certificate Balance immediately prior to such
Distribution Date. The term "Certificate Balance" in respect of any one or more
Classes of Certificates has the corresponding meaning. In no event shall the
aggregate distributions of principal to the holders of the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8, Class M, Class
B-1 and Class B-2 Certificates exceed the Initial Class A-1 Certificate Balance,
the Initial Class A-2 Certificate Balance, the Initial Class A-3 Certificate
Balance, the Initial Class A-4 Certificate Balance, the Initial Class A-5
Certificate Balance, the Initial Class A-6 Certificate Balance, the Initial
Class A-7 Certificate Balance, the Initial Class A-8 Certificate Balance, the
Initial Class M Certificate Balance, the Initial Class B-1 Certificate Balance
and the Initial Class B-2 Certificate Balance, respectively.
 
RESERVE ACCOUNT
 
    On the Closing Date, the Trustee shall establish an account (the "Reserve
Account") for the benefit of the Certificateholders. The Reserve Account shall
have an initial balance of $6,859,826 (1.00% of the Cut-off Date Pool Principal
Balance) on the Closing Date. In the event that amounts on deposit in the
Reserve Account fall below the Reserve Account Cap, the Reserve Account will be
replenished on each Distribution Date by the deposit therein of the portion of
the Available Distribution Amount remaining after the distribution of all
amounts required to be paid to the Class A, Class M and Class B
Certificateholders and
 
                                      S-53
<PAGE>
after the payment of the Monthly Servicing Fee and reimbursement of Monthly
Advances has been made as described above under "--Distributions--Priorities"
until the amount on deposit in the Reserve Account equals $6,859,826, or, if
there has been a Reserve Account Trigger and such Reserve Account Trigger has
not been cured, $13,719,652 (2.00% of the Cut-off Date Pool Principal Balance)
(the "Reserve Account Cap"). On or prior to each Distribution Date, a withdrawal
will be made from the Reserve Account, if necessary, in an amount (the "Reserve
Account Draw Amount") equal to the lesser of (i) the amount on deposit in the
Reserve Account and (ii) the amount by which the aggregate of amounts due to
Certificateholders in clauses (i) through (viii) under
"--Distributions--Priorities" above will exceed the Available Distribution
Amount on the related Distribution Date. The Reserve Account Draw Amount will be
distributed together with the Available Distribution Amount. Reserve Account
Draw Amounts will only be available to make payments to Certificateholders of
the amounts described in clause (ii) of the immediately preceding sentence.
Funds in the Reserve Account will be invested in Eligible Investments selected
by the Class R Certificateholders, which investments will be subject to the same
investment criteria as the investment of funds on deposit in the Certificate
Account.
 
    "Reserve Account Trigger" means, as of any Distribution Date, if any of the
following conditions are in effect as of such Distribution Date or were in
effect for any of the immediately preceding eleven Distribution Dates:
 
        (i) the Cumulative Realized Losses as of such Distribution Date exceeds
            the percentage with respect to such Distribution Date as set forth
            in the Agreement;
 
        (ii) the Current Realized Loss Ratio as of such Distribution Date
             exceeds 2.5%;
 
       (iii) the Average Sixty-Day Delinquency Ratio as of such Distribution
             Date exceeds 3.5%; or
 
        (iv) the Average Thirty-Day Delinquency Ratio as of such Distribution
             Date exceeds 5.5%.
 
    The "Average Sixty-Day Delinquency Ratio" and the "Average Thirty-Day
Delinquency Ratio" are, in general, the ratios of the average of the aggregate
principal balances of Contracts delinquent 60 days or more and 30 days or more,
respectively, for the preceding three Collection Periods (determined as of the
last day of each such Collection Period) to the average Pool Scheduled Principal
Balance for such periods. "Cumulative Realized Losses" are, in general, the
aggregate net liquidation losses (calculated as specified in the Agreement) in
respect of Liquidated Contracts since the Cut-off Date. The "Current Realized
Loss Ratio" is, in general, the ratio of the aggregate net liquidation losses in
respect of Liquidated Contracts for the periods specified in the Agreement to an
average Pool Scheduled Principal Balance specified in the Agreement.
 
    On the earlier to occur of the Distribution Date on which the Class B-2
Certificate Balance is reduced to zero and the Final Scheduled Distribution
Date, after giving effect to any distributions to be made on such Distribution
Date, the amount, if any, on deposit in the Reserve Account will be distributed
to the Class R Certificateholders.
 
SUBORDINATION
 
    The rights of the holders of the Subordinate Certificates to receive
distributions of available amounts in the Trust Fund will be subordinate, to the
extent described herein, to such rights of the holders of the Senior
Certificates. This subordination is intended to enhance the likelihood of
regular receipt by the holders of the Senior Certificates of the full amount of
interest and principal distributable thereon and to afford such holders
protection against losses on Liquidated Contracts.
 
    Similarly, the rights of the holders of the Class B Certificates to receive
distributions due them from available amounts in the Trust Fund will be
subordinated, to the extent described herein, to such rights of the holders of
the Class M Certificates, and the rights of the holders of the Class B-2
Certificates to receive the distributions due them from available amounts in the
Trust Fund will be subordinated, to the extent
 
                                      S-54
<PAGE>
described herein, to such rights of the holders of the Class B-1 Certificates.
Subject to the subordination of the Subordinate Certificates to the Senior
Certificates, this subordination of the Class B Certificates to the Class M
Certificates and of the Class B-2 Certificates to the Class M and Class B-1
Certificates is intended to enhance the likelihood of regular receipt by the
holders of the Class M Certificates and the holders of the Class B-1
Certificates, respectively, of the full amount of the distributions due them and
to afford such holders protection against losses on Liquidated Contracts.
 
    The protection afforded to the holders of Senior Certificates by means of
the subordination of the Subordinate Certificates, to the Class M
Certificateholders by the subordination of the Class B Certificates and to the
Class B-1 Certificateholders by the subordination of the Class B-2 Certificates
(in each case, to the extent described herein) will be accomplished by the
application of the Available Distribution Amount (together with any Reserve
Account Draw Amount) in the order specified under "Distributions" above.
Accordingly, in the event that the Available Distribution Amount (together with
any Reserve Account Draw Amount) on any Distribution Date is not sufficient to
permit the distribution of the amount of interest and the Formula Principal
Distribution Amount due to the holders of any Class of Certificates, the
subordination is intended to protect such Certificateholders by the right of
such Certificateholders to receive distributions of the Available Distribution
Amount in respect of interest and the Formula Principal Distribution Amount that
would otherwise have been distributable to the Certificateholders of any Class
subordinate in priority of distribution to such Class, until any shortfall in
distributions to the holders of the related senior Class or Classes of
Certificates in respect thereof has been satisfied, to the extent described
herein.
 
LOSSES ON LIQUIDATED CONTRACTS
 
    As described above, the Total Regular Principal Amount distributable to the
holders of the Series 1998-2 Regular Certificates on each Distribution Date
includes the Scheduled Principal Balance of each Contract that became a
Liquidated Contract during the immediately preceding Collection Period. The
Liquidation Proceeds, net of (i) certain expenses incurred to liquidate such
Liquidated Contract, (ii) all accrued and unpaid interest thereon and (iii) all
Monthly Advances required to be made in respect of such Liquidated Contract (the
"Net Liquidation Proceeds"), may be less than the Scheduled Principal Balance of
such Liquidated Contract. Under such circumstances, the loss on the Liquidated
Contract, in the amount of the deficiency between the Net Liquidation Proceeds
and the Scheduled Principal Balance of such Liquidated Contract, may be covered
to the extent of the amount (the "Excess Interest"), if any, by which the
interest collected on nondefaulted Contracts during the same Collection Period
exceeds the sum of (i) interest distributions due to holders of the Series
1998-2 Regular Certificates and (ii) the Monthly Servicing Fee.
 
    The effect of any losses on Liquidated Contracts during a Collection Period
in excess of (i) the Excess Interest, if any, and (ii) the funds, if any, on
deposit in the Reserve Account generally will reduce scheduled interest payments
on the Class B-2 Certificates, the Class B-1 Certificates and the Class M
Certificates, in that order, and may reduce the Pool Scheduled Principal Balance
below the aggregate Certificate Balance of the Certificates on the related
Distribution Date. In the event the Pool Scheduled Principal Balance falls below
the aggregate Certificate Balance of the Certificates on any Distribution Date,
shortfalls and/or losses will arise with respect to the Certificates, which
shortfalls and/or losses will be borne by the Class B-2 Certificateholders, the
Class B-1 Certificateholders, the Class M Certificateholders and the Senior
Certificateholders, in that order.
 
EXAMPLE OF DISTRIBUTIONS
 
    The following chart sets forth an example of the flow of funds on the
Certificates for the Distribution Date occurring in July, 1998:

                                          not a business day, the next business day.)
</TABLE>
 
    Succeeding months follow the pattern of (B) through (E).
 
(A) The Cut-off Date Pool Principal Balance on May 31, 1998 will be computed as
    described under "-- Conveyance of Contracts" above.
 
(B) Scheduled Payments, principal prepayments and Liquidation Proceeds (net of
    Liquidation Expenses) and amounts for the repurchase of Contracts may be
    received at any time during this period and will be distributed to
    Certificateholders on July 10, 1998. When a partial prepayment is made or a
    Contract is prepaid in full, interest on the amount prepaid is collected
    from the Obligor only to the date of payment. The Available Distribution
    Amount for the distribution on July 10, 1998 is described under "--Payments
    on Contracts; Certificate Account" above.
 
(C) Distributions on July 10, 1998 will be made to Certificateholders of record
    at the close of business on July 9, 1998.
 
(D) On July 5, 1998 (three business days prior to the Distribution Date), the
    Servicer will determine the amounts of principal and interest which will be
    passed through on July 10, 1998 to Certificateholders.
 
(E) On July 10, 1998, the amounts determined on July 5, 1998 will be distributed
    to Certificateholders.
 
ADVANCES
 
    For each Distribution Date, the Servicer will be obligated to make an
advance (a "Monthly Advance") equal to the lesser of (i) delinquent scheduled
payments of principal and interest on the Contracts that were due in the
preceding Collection Period and (ii) the amount, if any, by which scheduled
distributions of principal and interest due on the Series 1998-2 Regular
Certificates exceeds the amount specified in clause (b) of the definition of
Available Distribution Amount (as set forth above under "--Payments on
Contracts; Certificate Account"), except to the extent, in the Servicer's
judgment, such advance would not be recoverable from related late payments,
Liquidation Proceeds or otherwise (a "Nonrecoverable Advance").
 
    The aggregate amount of any additional advances made by the Servicer that
have not been reimbursed to the Servicer as described below is referred to
herein as the "Outstanding Amount Advanced." The Servicer may apply any Excess
Contract Payments in the Certificate Account (rather than its own funds) to make
all or a portion of a Monthly Advance, but must replace such Excess Contract
Payments to the extent required to make scheduled payments on the related
Contracts. In addition, upon the determination that a Nonrecoverable Advance has
been made in respect of a Contract, the Servicer will reimburse itself (but only
to the extent of the Outstanding Amount Advanced) out of funds in the
Certificate Account for the delinquent Scheduled Payments on such Contract or
out of any other funds in the Certificate Account.
 
    In making Monthly Advances, the Servicer will be attempting to maintain a
regular flow of scheduled interest and principal to the Series 1998-2 Regular
Certificateholders rather than to guarantee or insure against losses.
 
                                      S-56
<PAGE>
    The Servicer will also be obligated to make advances, to the extent
recoverable out of Liquidation Proceeds or otherwise, in respect of certain
taxes and insurance premiums not paid by an Obligor on a timely basis. Funds so
advanced are reimbursable to the Servicer as provided in the Agreement.

       Distribution Date;
 
    (b) the amount of such distribution on each Class of Certificates which
       constitutes principal;

       if any, between the remaining principal balances of the replaced
       Contracts and the Eligible Substitute Contracts;
 
    (k) the aggregate principal balances of all Contracts that are not
       Liquidated Contracts and in respect of which the related Manufactured
       Homes have been repossessed or foreclosed upon;

       Collection Period immediately preceding such Distribution Date, expressed
       in dollars;

       Collection Period immediately preceding such Distribution Date, expressed
       as a percentage of the Cut-off Date Pool Principal Balance;
 
    (n) the amount of any Monthly Advance for such Distribution Date and the
       aggregate amount of Monthly Advances that remain outstanding as of such
       Distribution Date;
 
    (o) the Weighted Average Net Contract Rate for the Collection Period
       immediately preceding the month of such Distribution Date; and
 
    (p) the number of Manufactured Homes currently held by the Servicer due to
       repossessions and the aggregate principal balance of the related
       defaulted Contracts.
 
    In addition, within a reasonable period of time after the end of each
calendar year, the Trustee will furnish a report to each holder of a Series
1998-2 Regular Certificate of record at any time during such calendar year as to
the aggregate of amounts reported pursuant to clauses (b) and (c) above for such
calendar year.

OPTIONAL TERMINATION AND TERMINATION AUCTION
 
    The Agreement provides that on any Distribution Date after the Distribution
Date on which the Pool Scheduled Principal Balance is less than 10% of the
Cut-off Date Pool Principal Balance, the Servicer will have the option to
repurchase, upon giving notice mailed no later than the 10th day of the month
next preceding the month of the exercise of such option, all outstanding
Contracts at a price equal to the greater of (a) the sum of (x) 100% of the
Scheduled Principal Balance of each Contract (other than any Contract as to
which the related Manufactured Home has been acquired and not yet disposed of
and whose fair market value is included pursuant to clause (y) below) as of the
final Distribution Date, and (y) the fair market value of such acquired property
(as determined by the Servicer), and (b) the aggregate fair market value (as
determined by the Servicer) of all of the assets of the Trust Fund, plus, in the
case of both clause (a) and (b), an amount sufficient to reimburse
Certificateholders for any shortfall in interest due thereto in respect of prior
Distribution Dates. Notwithstanding the foregoing, the Servicer's option shall
not be exercisable if there will not be distributed to the holders of each
outstanding Class of 1998-2 Regular Certificates an amount equal to the
respective Certificate Balances of such Certificates together with any shortfall
in interest due on such Certificates in respect of prior Distribution Dates and
one month's interest at the applicable Pass-Through Rates on such unpaid
Certificate Balances (collectively, the "Minimum Termination Amount").
 
    On any Distribution Date after the Distribution Date on which the Pool
Scheduled Principal Balance is less than 10% of the Cut-off Date Pool Principal
Balance, the Servicer may also direct the Trustee to conduct a Termination
Auction for the sale of all Contracts then outstanding in the Trust Fund, and in
any case the Servicer shall be obligated to direct the Trustee to conduct such a
Termination Auction within 90 days of the Distribution Date on which the Pool
Scheduled Principal Balance is less than 10% of the Cut-off Date Pool Principal
Balance, unless the Servicer has exercised the repurchase option described
above. The Servicer shall give notice mailed no later than 10 days preceding the
date on which any Termination Auction is to occur. The Trustee will solicit each
registered Certificateholder, the Sellers and one or more active participants in
the asset-backed securities or manufactured housing contract market that are not
affiliated with BankAmerica Corporation to make a bid to purchase the Contracts
at the Termination Auction. The Trustee will sell all the Contracts to the
highest bidder, subject, among other things, to: (i) the requirement that the
highest bid equal or exceed the Minimum Termination Amount; and (ii) the
requirement that at least one bid be tendered by an active participant in the
asset-backed securities or manufactured housing contract market that is not
affiliated with Bank of America, NT&SA or Bank of America, FSB. If the foregoing
requirements are satisfied, the successful bidder or bidders shall deposit the
aggregate purchase price for the Contracts in the Certificate Account. If the
foregoing requirements are not satisfied, the purchase shall not occur and
distributions will continue to be made on the Certificates. Any sale and
consequent termination of the Trust Fund as a result of a Termination Auction
must constitute a "qualified liquidation" of the Trust Fund under Section 860F
of the Code.
 
TERMINATION OF THE AGREEMENT
 
    The Agreement will terminate upon the last action required to be taken by
the Trustee on the final Distribution Date following the earlier of (i) the
purchase by the Servicer of all Contracts and all property acquired in respect
of any Contract remaining in the Trust Fund as described above under "--Optional
Termination and Termination Auction" or (ii) the final payment or other
liquidation (or any advance with respect thereto) of the last Contract remaining
in the Trust Fund or the disposition of all property acquired upon repossession
of any Manufactured Home or (iii) the sale in a Termination Auction of all
Contracts and all other property acquired in respect of any Contract remaining
in the Trust Fund as described above under "--Optional Termination and
Termination Auction."
 
    Upon presentation and surrender of the Series 1998-2 Regular Certificates,
the Trustee shall cause to be distributed, to the extent of funds available, to
such Certificateholders on the final Distribution Date in proportion to their
respective Percentage Interests an amount equal to the respective unpaid
Certificate
 
                                      S-58
<PAGE>
Balances of the Series 1998-2 Regular Certificates, together with any unpaid
interest on such Certificates due on prior Distribution Dates and one month's
interest at the applicable pass-through rates on such unpaid Certificate
Balances; provided that such funds will be distributed in the applicable order
of priority specified under "--Distributions" above. If the Agreement is then
being terminated, any amount which remains on deposit in the Certificate Account
(other than amounts retained to meet claims) after distribution to the holders
of the Series 1998-2 Regular Certificates will be distributed to the Class R
Certificateholders.
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
    The Servicer will administer, service and make collections on the Contracts,
exercising the degree of care that the Servicer exercises with respect to
similar contracts serviced by the Servicer.
 
    Subject to the requirements of applicable law, the Servicer will be required
to commence repossession and other realization procedures with respect to any
defaulted Contract promptly after the Servicer determines that such Contract
will not be brought current. The Servicer may rescind, cancel or make material
modifications of the terms of a Contract (including modifying the amounts and
Due Dates of Scheduled Payments) in connection with a default or imminent
default thereunder.
 
SERVICING COMPENSATION; CERTAIN OTHER MATTERS REGARDING THE SERVICER
 
    For its servicing of the Contracts, the Servicer will be entitled to receive
a monthly servicing fee equal to the product of one-twelfth of 1.00% and the
Pool Scheduled Principal Balance for the related Distribution Date (the "Monthly
Servicing Fee"), whether or not the related Scheduled Payments on the Contracts
are received. The Available Distribution Amount will be net of the Monthly
Servicing Fee. See "--Payments on the Contracts; Certificate Account" above.
 
    As part of its servicing fees, the Servicer will also be entitled to retain,
as compensation for the additional services provided in connection therewith,
any fees for late payments made by Obligors, extension fees paid by Obligors for
the extension of scheduled payments and assumption fees for permitted
assumptions of Contracts by purchasers of the related Manufactured Homes.
 
THE TRUSTEE
 
    The First National Bank of Chicago (the "Trustee") has its corporate trust
offices at One First National Plaza, Chicago, Illinois 60670-0126. The Trustee
may resign at any time, in which event the Sellers will be obligated to appoint
a successor Trustee. The Sellers may also remove the Trustee if the Trustee
ceases to be eligible to continue as such under the Agreement or if the Trustee
becomes insolvent. In such circumstances, the Sellers will also be obligated to
appoint a successor Trustee. Any resignation or removal of the Trustee and
appointment of a successor Trustee will not become effective until acceptance of
the appointment by the successor Trustee.
 
    The Agreement requires the Trustee to maintain, at its own expense, an
office or agency in New York City or Chicago where Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Trustee and the certificate registrar in respect of the
Certificates pursuant to the Agreement may be served.
 
    The Trustee, or any of its affiliates, in its individual or any other
capacity, may become the owner or pledgee of Certificates with the same rights
as it would have if it were not Trustee.
 
    The Trustee will also act as paying agent, certificate registrar and
authenticating agent under the Agreement.

REGISTRATION OF THE OFFERED CERTIFICATES
 
    The Offered Certificates will be book-entry Certificates (the "Book-Entry
Certificates"). Persons acquiring beneficial ownership interests in the Offered
Certificates ("Certificate Owners") will hold their Offered Certificates through
DTC in the United States, or Cedel Bank, societe anonyme ("Cedel") or Euroclear
System ("Euroclear") in Europe if they are participants of such systems, or
indirectly through organizations which are participants in such systems. The
Book-Entry Certificates will be issued in one or more certificates which equal
the aggregate principal balance of the Offered Certificates and will initially
be registered in the name of Cede & Co., the nominee of DTC. Cedel and Euroclear
will hold omnibus positions on behalf of their participants through customers'
securities accounts in Cedel's and Euroclear's names on the books of their
respective depositaries which in turn will hold such positions in customers'
securities accounts in the depositaries' names on the books of DTC. Citibank
will act as depositary for Cedel and The Chase Manhattan Bank will act as
depositary for Euroclear (in such capacities, individually the "Relevant
Depositary" and collectively the "European Depositaries"). Except as described
below, no person acquiring a Book-Entry Certificate (each, a "Beneficial Owner")
will be entitled to receive a physical certificate representing such Certificate
(a "Definitive Certificate"). Unless and until Definitive Certificates are
issued, it is anticipated that the only "Certificateholder" of the Offered
Certificates will be Cede & Co., as nominee of DTC. Certificate Owners will not
be Certificateholders as that term is used in the Agreement. Certificate Owners
are only permitted to exercise their rights indirectly through Participants and
DTC.
 
    The beneficial owner's ownership of a Book-Entry Certificate will be
recorded on the records of the brokerage firm, bank, thrift institution or other
financial intermediary (each, a "Financial Intermediary") that maintains the
beneficial owner's account for such purpose. In turn, the Financial
Intermediary's ownership of such Book-Entry Certificate will be recorded in the
records of DTC (or of a participating firm that acts as agent for the Financial
Intermediary, whose interest will in turn be recorded on the records of DTC, if
the beneficial owner's Financial Intermediary is not a DTC participant and on
the records of Cedel or Euroclear, as appropriate).
 
    Certificate Owners will receive all distributions of principal of and
interest on the Offered Certificates from the Trustee through DTC and DTC
participants. While the Offered Certificates are outstanding (except under the
circumstances described below), under the rules, regulations and procedures
creating and affecting DTC and its operations (the "Rules"), DTC is required to
make book-entry transfers among Participants on whose behalf it acts with
respect to the Offered Certificates and is required to receive and transmit
distributions of principal of, and interest on, the Offered Certificates.
Participants and indirect participants with whom Certificate Owners have
accounts with respect to Offered Certificates are similarly required to make
book-entry transfers and receive and transmit such distributions on behalf of
their respective Certificate Owners. Accordingly, although Certificate Owners
will not possess certificates representing their respective interests in the
Offered Certificates, the Rules provide a mechanism by which Certificate Owners
will receive distributions and will be able to transfer their interest.
 
    Certificateholders will not receive or be entitled to receive certificates
representing their respective interests in the Offered Certificates, except
under the limited circumstances described below. Unless and until Definitive
Certificates are issued, Certificateholders who are not Participants may
transfer ownership of Offered Certificates only through Participants and
indirect participants by instructing such Participants and indirect participants
to transfer Offered Certificates, by book-entry transfer, through DTC for the
account of the purchasers of such Offered Certificates, which account is
maintained with their respective Participants. Under the Rules and in accordance
with DTC's normal procedures, transfers of ownership of Offered Certificates
will be executed through DTC and the accounts of the respective Participants at
DTC will be debited and credited. Similarly, the Participants and indirect
participants will make debits or credits, as the case may be, on their records
on behalf of the selling and purchasing Certificateholders.
 
                                      S-60

    Because of time zone differences, credits of securities received in Cedel or
Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the business day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
Cedel Participants on such business day. Cash received in Cedel or Euroclear as
a result of sales of securities by or through a Cedel Participant (as defined
below) or Euroclear Participant (as defined below) to a DTC Participant will be
received with value on the DTC settlement date but will be available in the
relevant Cedel or Euroclear cash account only as of the business day following
settlement in DTC. For information with respect to tax documentation procedures
relating to the Certificates, see "Certain Federal Income Tax Consequences--
REMIC Certificates--C. Taxation of Regular Certificates--9. Taxation of Certain
Foreign Investors" and "--10. Backup Withholding" in the Prospectus and "Global
Clearance, Settlement and Tax Documentation Procedures--Certain U.S. Federal
Income Tax Documentation Requirements" in Annex I hereto.
 
    Transfers between Participants will occur in accordance with DTC rules.
Transfers between Cedel Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
    Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Cedel
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by a counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. Cedel Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.
 
    DTC, which is a New York-chartered limited purpose trust company, performs
services for its participants, some of which (and/or their representatives) own
DTC. In accordance with its normal procedures, DTC is expected to record the
positions held by each DTC participant in the Book-Entry Certificates, whether
held for its own account or as a nominee for another person. In general,
beneficial ownership of Book-Entry Certificates will be subject to the Rules, as
in effect from time to time.
 
    Cedel Bank, SOCIETE ANONYME, 67 Bd Grande-Duchesse Charlotte, L-1331
Luxembourg, was incorporated in 1970 as a limited company under Luxembourg law.
Cedel is owned by banks, securities dealers and financial institutions, and
currently has about 100 shareholders, including U.S. financial institutions or
their subsidiaries. No single entity may own more than five percent of Cedel's
stock.
 
    Cedel is registered as a bank in Luxembourg, and as such is subject to
regulation by the Institute Monetaire Luxembourgeois, "IML", the Luxembourg
Monetary Authority, which supervises Luxembourg banks.
 
    Cedel holds securities for its customers ("Cedel Participants") and
facilitates the clearance and settlement of securities transactions by
electronic book-entry transfers between their accounts. Cedel provides various
services, including safekeeping, administration, clearance and settlement of
internationally traded securities and securities lending and borrowing. Cedel
also deals with domestic securities markets in several countries through
established depository and custodial relationships. Cedel has established an
electronic bridge with Morgan Guaranty Trust as the Euroclear Operator in
Brussels to facilitate settlement of trades between systems. Cedel currently
accepts over 70,000 securities issues on its books.
 
    Cedel's customers are world-wide financial institutions including
underwriters, securities brokers and dealers, banks, trust companies and
clearing corporations. Cedel's United States customers are limited to
 
                                      S-61
<PAGE>
securities brokers and dealers and banks. Currently, Cedel has approximately
3,000 customers located in over 60 countries, including all major European
countries, Canada, and the United States. Indirect access to Cedel is available
to other institutions which clear through or maintain a custodial relationship
with an account holder of Cedel.
 
    Euroclear was created in 1968 to hold securities for its participants
("Euroclear Participants") and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 29 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of Morgan
Guaranty Trust Company of New York (the "Euroclear Operator"), under contract
with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the
"Cooperative"). All operations are conducted by the Euroclear Operator, and all
Euroclear securities clearance accounts and Euroclear cash accounts are accounts
with the Euroclear Operator, not the Cooperative. The Cooperative establishes
policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants
include banks (including central banks), securities brokers and dealers and
other professional financial intermediaries. Indirect access to Euroclear is
also available to other firms that clear through or maintain a custodial
relationship with a Euroclear Participant, either directly or indirectly.
 
    The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
and the New York State Banking Department, as well as the Belgian Banking
Commission.
 
    Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from Euroclear and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a tangible basis with
attribution of specific certificates to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.
 
    Distributions on the Book-Entry Certificates will be made on each
Distribution Date by the Trustee to DTC. DTC will be responsible for crediting
the amount of such payments to the accounts of the applicable DTC participants
in accordance with DTC's normal procedures. Each DTC participant will be
responsible for disbursing such payments to the beneficial owners of the
Book-Entry Certificates that it represents and to each Financial Intermediary
for which it acts as agent. Each such Financial Intermediary will be responsible
for distributing funds to the beneficial owners of the Book-Entry Certificates
that it represents.
 
    Under a book-entry format, beneficial owners of the Book-Entry Certificates
may experience some delay in their receipt of payments, since such payments will
be forwarded by the Trustee to Cede. Distributions with respect to Certificates
held through Cedel or Euroclear will be credited to the cash accounts of Cedel
Participants or Euroclear Participants in accordance with the relevant system's
rules and procedures, to the extent received by the Relevant Depositary. Such
distributions will be subject to tax reporting in accordance with relevant
United States tax laws and regulations. See "Certain Federal Income Tax
Consequences--REMIC Certificates--C. Taxation of Regular Certificates--9.
Taxation of Certain Foreign Investors" and "--10. Backup Withholding" in the
Prospectus. Because DTC can only act on behalf of Financial Intermediaries, the
ability of a beneficial owner to pledge Book-Entry Certificates to persons or
entities that do not participate in the Depository system, or otherwise take
actions in respect of such Book-Entry Certificates, may be limited due to the
lack of physical certificates for such Book-Entry
 
                                      S-62
<PAGE>
Certificates. In addition, issuance of the Book-Entry Certificates in the
book-entry form may reduce the liquidity of such Certificates in the secondary
market since certain potential investors may be unwilling to purchase
Certificates for which they cannot obtain physical certificates.
 
    Monthly and annual reports on the Trust will be provided to Cede, as nominee
of DTC, and may be made available by Cede to beneficial owners upon request, in
accordance with the rules, regulations and procedures creating and affecting the
Depository, and to the Financial Intermediaries to whose DTC accounts the
Book-Entry Certificates of such beneficial owners are credited.
 
    DTC has advised the Trustee that, unless and until Definitive Certificates
are issued, DTC will take any action permitted to be taken by the holders of the
Book-Entry Certificates under the Agreement only at the direction of one or more
Financial Intermediaries to whose DTC accounts the Book-Entry Certificates are
credited, to the extent that such actions are taken on behalf of Financial
Intermediaries whose holdings include such Book-Entry Certificates. Cedel or the
Euroclear Operator, as the case may be, will take any other action permitted to
be taken by a Certificateholder under the Agreement on behalf of a Cedel
Participant or Euroclear Participant only in accordance with its relevant rules
and procedures and subject to the ability of the Relevant Depository to effect
such actions on its behalf through DTC. DTC may take actions, at the direction
of the related Participants, with respect to some Offered Certificates which
conflict with actions taken with respect to other Offered Certificates.
 
    Definitive Certificates will be issued to beneficial owners of the
Book-Entry Certificates, or their nominees, rather than to DTC, only if (a) DTC
or Bank of America, FSB advises the Trustee in writing that DTC is no longer
willing, qualified or able to discharge properly its responsibilities as nominee
and depository with respect to the Book-Entry Certificates and Bank of America,
FSB or the Trustee is unable to locate a qualified successor, (b) Bank of
America, FSB, at its sole option, with the consent of the Trustee, elects to
terminate a book-entry system through DTC or (c) after the occurrence of an
event of default under the Agreement, beneficial owners having Percentage
Interests aggregating not less than 51% of the Book-Entry Certificates advise
the Trustee and DTC through the Financial Intermediaries and the DTC
participants in writing that the continuation of a book-entry system through DTC
(or a successor thereto) is no longer in the best interests of beneficial
owners.
 
    Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee will be required to notify all beneficial
owners of the occurrence of such event and the availability through DTC of
Definitive Certificates. Upon surrender by DTC of the global certificate or
certificates representing the Book-Entry Certificates and instructions for
re-registration, the Trustee will issue Definitive Certificates, and thereafter
the Trustee will recognize the holders of such Definitive Certificates as
Certificateholders under the Agreement.
 
    Although DTC, Cedel and Euroclear have agreed to the foregoing procedures in
order to facilitate transfer of Offered Certificates among participants of DTC,
Cedel and Euroclear, they are under no obligation to perform or continue to
perform such procedures and such procedures may be discontinued at any time.
 
    Neither Bank of America, NT&SA nor Bank of America, FSB, in their capacity
as Sellers, the Servicer nor the Trustee will have any responsibility for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of the Book-Entry Certificates held by Cede & Co., as
nominee for DTC, or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    Upon the issuance of the Offered Certificates, Orrick, Herrington &
Sutcliffe LLP, special counsel to the Sellers, will deliver its opinion that,
assuming (i) the making of appropriate elections, (ii) compliance with
applicable provisions of the Code, including Sections 860A through 860G of the
Code (the "REMIC Provisions"), and related Treasury regulations, and (iii)
compliance by the Sellers, the Servicer and the Trustee with all of the
provisions of the related Agreements, (a) the Trust Fund will qualify, for
federal income tax purposes, as a "real estate mortgage investment conduit" (a
"REMIC") within the meaning of the REMIC Provisions, and (b) the Offered
Certificates, together with the Class B-2 Certificates, evidence the "regular
interests" in such REMIC and (c) the Class R Certificates is the sole class of
"residual interests" in such REMIC, respectively, each within the meaning of the
REMIC Provisions in effect on the date hereof.
 
    The following general discussion of the anticipated federal income tax
consequences of the purchase, ownership and disposition of Offered Certificates,
to the extent it relates to matters of law or legal conclusions with respect
thereto, represents the opinion of Orrick, Herrington & Sutcliffe LLP subject to
the qualifications set forth herein. In addition, Orrick, Herrington & Sutcliffe
LLP has prepared or reviewed the statements in this Prospectus Supplement under
the heading "Certain Federal Income Tax Consequences," and is of the opinion
that such statements are correct in all material respects. Such statements are
intended as an explanatory discussion of the possible effects of the
classification of the Trust Fund as a REMIC for federal income tax purposes on
investors generally and of related tax matters affecting investors generally,
but do not purport to furnish information in the level of detail or with the
attention to an investor's specific tax circumstances that would be provided by
an investor's own tax advisor. Accordingly, each investor is advised to consult
its own tax advisors with regard to the tax consequences to it of investing in
the Offered Certificates.
 
    The Offered Certificates will be Regular Certificates (as defined in the
Prospectus under "Certain Federal Income Tax Consequences--REMIC Certificates").
Generally, the Offered Certificates will be treated as debt instruments for
federal income tax purposes. Holders of Offered Certificates will be required to
report income with respect to such Offered Certificates under the accrual method
of accounting, regardless of their normal tax accounting method.
 
    For federal income tax reporting purposes, the Class       and Class
      Certificates will be treated as having been issued with original issue
discount. All other classes of Offered Certificates will be treated as not
having been issued with original issue discount for federal income tax reporting
purposes. The prepayment assumption that will be used in determining the rate of
accrual of original issue discount, market discount and premium, if any, for
federal income tax purposes will be based on the assumption that, subsequent to
the date of any determination the Contracts will prepay at a rate equal to 170%
of the Prepayment Assumption. No representation is made that the Contracts will
prepay at that rate or at any other rate. See "Certain Federal Income Tax
Consequences--REMIC Certificates--C. Taxation of Regular Certificates--2.
Original Issue Discount" and "--5. Premium" in the Prospectus.
 
    If the method for computing original issue discount described in the
Prospectus results in a negative amount for any period with respect to a
Certificateholder, the amount of original issue discount allocable to such
period will be zero and such Certificateholder will be permitted to offset such
negative amount only against future original issue discount (if any)
attributable to such Certificates.
 
    In certain circumstances OID Regulations permit the holder of a debt
instrument to recognize original issue discount under a method that differs from
that used by the issuer. Accordingly, it is possible that the holder of a
Certificate may be able to select a method for recognizing original issue
discount that differs from that used by the REMIC administrator in preparing
reports to the Certificateholders and the IRS.
 
                                      S-64
<PAGE>
    Certain classes of the Offered Certificates may be treated for federal
income tax purposes as having been issued at a premium. Whether any holder of
such a class of Certificates will be treated as holding a certificate with
amortizable bond premium will depend on such Certificateholder's purchase price
and the distributions remaining to be made on such Certificate at the time of
its acquisition by such Certificateholder. Holders of such classes of
Certificates should consult their tax advisors regarding the possibility of
making an election to amortize such premium. See "Certain Federal Income Tax
Consequences--REMIC Certificates--C. Taxation of Regular Certificates" and "--5.
Premium" in the Prospectus.
 
    The Offered Certificates will be treated as assets described in Section
7701(a)(19)(C) of the Code and "real estate assets" under Section 856(c)(4)(A)
of the Code generally in the same proportion that the assets of the Trust Fund
would be so treated. In addition, interest on the Offered Certificates will be
treated as "interest on obligations secured by mortgages on real property" under
Section 856(c)(3)(B) of the Code generally to the extent that such Offered
Certificates are treated as "real estate assets" under Section 856(c)(4)(A) of
the Code. Moreover, the Offered Certificates (other than the Residual
Certificates) will be "qualified mortgages" within the meaning of Section
860G(a)(3) of the Code if transferred to another REMIC on its startup day in
exchange for a regular or residual interest therein. See "Certain Federal Income
Tax Consequences--REMIC Certificates" in the Prospectus.
 
    For further information regarding federal income tax consequences of
investing in the Offered Certificates, see "Certain Federal Income Tax
Consequences--REMICs" in the Prospectus.
 
                              ERISA CONSIDERATIONS
 
GENERAL
 
    The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
and Section 4975 of the Code impose certain restrictions on employee benefit or
other plans that are subject to ERISA and/or Section 4975 of the Code ("Plans")
and on persons who are fiduciaries with respect to such Plans. See "ERISA
Considerations" in the Prospectus.
 
    Prospective Plan investors should consult with their legal advisors
concerning the impact of ERISA and the Code, the applicability of the Exemption
(defined below) and other administrative exemptions under ERISA 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 general 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.
 
SENIOR CERTIFICATES
 
    The Department of Labor ("DOL") has granted to a predecessor of BancAmerica
Robertson Stephens, Morgan Stanley & Co. Incorporated, Goldman, Sachs & Co. and
an affiliate of NationsBanc Montgomery Securities LLC essentially identical
administrative exemptions (DOL Prohibited Transaction Exemption ("PTE") 96-92
(Exemption Application No. D-10335), 61 Fed. Reg. 66334 (Dec. 17, 1996), PTE
90-24 (Exemption Application No. D-8019), 55 Fed. Reg. 20548 (May 17, 1990), PTE
89-88 (Exemption Application No. D-7573), 54 Fed. Reg. 42581 (Oct. 17, 1989) and
PTE 93-31 (Exemption Application No. D-9105), 58 Fed. Reg. 28620 (May 14, 1993),
respectively, each as amended by PTE 97-34, 62 Fed. Reg. 39021 (July 21, 1997)
(collectively, the "Exemption")) from certain of the prohibited transaction
rules of ERISA. The Exemption exempts from the prohibitions of Sections 406(a)
and 407(a) of ERISA, and the related excise tax provisions of Section 4975 of
the Code, the purchase, holding and resale by Plans of pass-through certificates
representing interests in trusts that hold assets consisting primarily of
certain receivables, loans and other obligations that meet the general
conditions summarized below. The receivables covered by the Exemption include
manufactured housing installment sales contracts and installment loan agreements
secured by manufactured homes such as the Contracts. The Sellers
 
                                      S-65
<PAGE>
believe that the Exemption will apply to the acquisition and holding of Senior
Certificates by Plans and that all conditions of the Exemption other than those
within the control of the investors have been or will be met.
 
    Among the general conditions which must be satisfied for the Exemption to
apply to the acquisition, holding and resale by a Plan of the Senior
Certificates are the following:
 
        (l) The acquisition of the Senior Certificates by a Plan is on terms
    (including the price for the Senior Certificates) that are at least as
    favorable to the Plan as they would be in an arm's-length transaction with
    an unrelated party.
 
        (2) The rights and interests evidenced by the Senior Certificates
    acquired by the Plan are not subordinated to the rights and interests
    evidenced by other Certificates of the Trust.
 
        (3) The Senior Certificates acquired by the Plan have received a rating
    at the time of such acquisition that is in one of the three highest generic
    rating categories from either Standard & Poor's Ratings Services ("S&P"),
    Moody's, Fitch or Duff & Phelps Credit Rating Co.
 
        (4) The Trustee is not an affiliate of the Underwriters, Bank of
    America, NT&SA, Bank of America, FSB, any Obligor with respect to Contracts
    included in the Trust Fund constituting more than 5% of the aggregate
    unamortized principal balance of the assets in the Trust Fund, or any
    affiliate of such parties. (Such parties, and the Trustee and its
    affiliates, are sometimes referred to herein collectively as the "Restricted
    Group.") As of the date hereof, no Obligor with respect to Contracts
    included in the Trust Fund is an Obligor with respect to Contracts
    constituting more than 5% of the aggregate unamortized principal balance of
    the assets of the Trust Fund.
 
        (5) The sum of all payments made to and retained by the Underwriters in
    connection with the distribution of the Senior Certificates represents not
    more than reasonable compensation for underwriting the Senior Certificates.
    The sum of all payments made to and retained by the Sellers pursuant to the
    sale of the Contracts to the Trust Fund represents not more than the fair
    market value of such Contracts. The sum of all payments made to and retained
    by Bank of America, FSB, represents not more than reasonable compensation
    for Bank of America, FSB's services under the Agreement and reimbursement of
    Bank of America, FSB's reasonable expenses in connection therewith.
 
        (6) The Plan is an "accredited investor" as defined in Rule 501(a)(1) of
    Regulation D of the Securities and Exchange Commission under the Securities
    Act of 1933.
 
    In addition, the Exemption exempts from the prohibitions of Sections 406(a),
406(b) and 407(a) of ERISA, and the related excise tax provisions of Section
4975 of the Code, transactions undertaken in connection with the servicing,
management and operation of such a trust pursuant to a binding pooling and
servicing agreement, subject to the foregoing general conditions and to certain
additional requirements. The Sellers believe that the Exemption will apply to
such transactions undertaken with respect to the Trust Fund and the Contracts
and that all conditions of the Exemption other than those within the control of
the investors have been or will be met.
 
    The Exemption also exempts from the prohibition of Sections 406(b)(1) and
406(b)(2) of ERISA, and the related excise tax provisions of Section 4975 of the
Code, the direct or indirect sale, exchange or transfer of Senior Certificates
between either Seller or the Underwriters and a Plan when the person who has
discretionary authority or renders investment advice with respect to the
investment of the Plan's assets in the Senior Certificates (the "Fiduciary") is
(a) an obligor with respect to 5% or less of the fair market value of Contracts
in the Trust Fund or (b) an affiliate of any such person, subject to the general
conditions summarized above and to the following additional requirements:
 
        (1) No member of the Restricted Group is a sponsor of the Plan. (2) In
    connection with the initial issuance of Senior Certificates, at least 50% in
    Percentage Interests of such Class of Certificates
 
                                      S-66
<PAGE>
    is acquired by persons independent of the Restricted Group and at least 50%
    of the aggregate interest in the Trust Fund is acquired by persons
    independent of the Restricted Group.
 
        (3) The Plan's investment in the Senior Certificates does not exceed 25%
    in Percentage Interests of any such Class of Certificates outstanding at the
    time of acquisition.
 
        (4) Immediately after the acquisition of the Senior Certificates, no
    more than 25% of the assets of a Plan with respect to which the Fiduciary
    has discretionary authority or renders investment advice are invested in
    certificates representing an interest in a trust containing assets sold or
    serviced by the same entity.
 
    The Exemption also applies to the direct or indirect acquisition or
disposition of Senior Certificates by a Plan in the secondary market if certain
conditions are met and the continued holding of Senior Certificates acquired in
initial or secondary markets.
 
    Before purchasing a Senior Certificate, a fiduciary of a Plan should make
its own determination as to the availability of the exemptive relief provided in
the Exemption or the availability of any other prohibited transaction
exemptions, and whether the conditions of any such exemption will be applicable
to the Certificate. Any fiduciary of a Plan considering whether to purchase a
Senior Certificate should also carefully review with its own legal advisors the
applicability of the fiduciary duty and prohibited transaction provisions of
ERISA and Section 4975 of the Code to such investment. See "ERISA
Considerations" in the Prospectus.
 
CLASS M AND CLASS B-1 CERTIFICATES
 
    A Fiduciary or other person investing "plan assets" of any Plan will not be
permitted to purchase or hold the Class M and Class B-1 Certificates, unless
such person delivers to the Trustee the certificate or opinion referred to
below, as such actions may give rise to a non-exempt prohibited transaction
under ERISA or Section 4975 of the Code. See "ERISA Considerations" in the
Prospectus. Because the Class M and Class B-1 Certificates do not meet the
requirements of the Exemption, it does not provide exemptive relief for the
purchase or holding of such Certificates with "plan assets" of any Plan.
 
    In addition, no transfer of a Class M or Class B-1 Certificate shall be
registered unless the prospective transferee provides the Trustee, the Sellers
and the Servicer with (a) a certification to the effect that such transferee (1)
is neither an employee benefit plan subject to Section 406 or Section 407 of
ERISA or a plan subject to Section 4975 of the Code, the trustee of any such
plan or a person acting on behalf of any such plan nor a person using "plan
assets" of any such plan or (2) if such transferee is an insurance company, it
is purchasing such certificates with funds contained in an "insurance company
general account" (as such term is defined in Section V(e) of Prohibited
Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the purchase and
holding of such Certificates is eligible for the exemptive relief available
under Sections I and III of PTCE 95-60; or (b) an opinion of counsel (a "Benefit
Plan Opinion") satisfactory to the Trustee, the Sellers and the Servicer, and
upon which the Trustee, the Sellers and the Servicer shall be entitled to rely,
to the effect that the purchase or holding of such Class M or Class B-1
Certificate by the prospective transferee will not result in any non-exempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Trustee, the Sellers or the Servicer to any obligation in addition
to those undertaken by such entities in the Agreement, which opinion of counsel
shall not be an expense of the Trustee, the Sellers or the Servicer. Owners of
the Class M or Class B-1 Certificates will be deemed to make one of the
representations in clauses (a)(1) and (a)(2).

<PAGE>
                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS
 
LAND HOME AND LAND-IN-LIEU CONTRACTS
 
    GENERAL.  Approximately 11.36% (by principal balance) of the Contracts are
Land Home Contracts or Land-in-Lieu Contracts. The Land Home Contracts and the
Land-in-Lieu Contracts will be secured by either first mortgages or deeds of
trust on the real estate on which the manufactured home is located, depending
upon the prevailing practice in the state in which the underlying property is
located. A mortgage creates a lien upon the real property described in the
mortgage. There are two parties to a mortgage: the mortgagor, who is the
borrower, and the mortgagee, who is the lender. In a mortgage state, the
mortgagor delivers to the mortgagee a note or bond evidencing the loan and the
mortgage. Although a deed of trust is similar to a mortgage, a deed of trust has
three parties: the borrower, a lender as beneficiary, and a third-party grantee
called the trustee. Under a deed of trust, the borrower grants the property,
irrevocably until the debt is paid, in trust, generally with a power of sale, to
the trustee to secure payment of the loan. The trustee's authority under a deed
of trust and the mortgagee's authority under a mortgage are governed by the
express provisions of the deed of trust or mortgage, applicable law, and, in
some cases, with respect to the deed of trust, the directions of the
beneficiary.
 
    FORECLOSURE.  Foreclosure of a mortgage is generally accomplished by
judicial action. Generally, the action is initiated by the service of legal
pleadings upon all parties having an interest of record in the real property.
Delays in completion of the foreclosure occasionally may result from
difficulties in locating necessary parties defendants. When the mortgagee's
right to foreclosure is contested, the legal proceedings necessary to resolve
the issue can be time-consuming and expensive. After the completion of a
judicial foreclosure proceeding, the court may issue a judgment of foreclosure
and appoint a receiver or other officer to conduct the sale of the property. In
some states, mortgages may also be foreclosed by advertisement, pursuant to a
power of sale provided in the mortgage. Foreclosure of a mortgage by
advertisement is essentially similar to foreclosure of a deed of trust by
non-judicial power of sale.
 
    Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale under a specific provision in the deed of trust that authorizes
the trustee to sell property to a third party upon any default by the borrower
under the terms of the note or deed of trust. In certain states, such
foreclosure also may be accomplished by judicial action in the manner provided
for foreclosure of mortgages. In some states the trustee must record a notice of
default and send a copy to the borrower-trustor and to any person who has
recorded a request for a copy of a notice of default and the notice of sale. In
addition, the trustee must provide notice in some states to any other individual
having an interest of record in the real property, including any junior
lienholders. If the deed of trust is not reinstated within any applicable cure
period, a notice of sale must be posted in a public place and, in most states,
published for a specified period of time in one or more newspapers. In addition,
some state laws require that a copy of the notice of sale be posted on the
property and sent to all parties having an interest of record in the property.
 
    In some states, the borrower-trustor has the right to reinstate the loan at
any time following default until shortly before the trustee's sale. In general,
the borrower, or any other person having a junior encumbrance on the real
estate, may, during a reinstatement period, cure the default by paying the
entire amount in arrears plus the costs and expenses incurred in enforcing the
obligation. Certain state laws control the amount of foreclosure expenses and
costs, including attorneys' fees, that may be recovered by a lender.
 
    In the case of foreclosure under either a mortgage or a deed of trust, the
sale by the receiver or other designated officer, or by the trustee, is a public
sale. However, because of the difficulty a potential buyer at the sale would
have in determining the exact status of title and because the physical condition
of the property may have deteriorated during the foreclosure proceedings, it is
not common for a third party to purchase the property at the foreclosure sale.
Rather, the lender generally purchases the property from the trustee or receiver
for an amount equal to the unpaid principal amount of the note, accrued and
unpaid interest and the expenses of foreclosure. Thereafter, subject to the
right of the borrower in some states to
 
                                      S-68
<PAGE>
remain in possession during the redemption period, the lender will assume the
burdens of ownership, including obtaining hazard insurance and making such
repairs at its own expense as are necessary to render the property suitable for
sale. The lender commonly will obtain the services of a real estate broker and
pay the broker a commission in connection with the sale of the property.
Depending upon market conditions, the ultimate proceeds of the sale of the
property may not equal the lender's investment in the property.
 
    RIGHTS OF REDEMPTION.  In some states, after sale pursuant to a deed of
trust or foreclosure of a mortgage, the borrower and certain foreclosed junior
lienors are given a statutory period in which to redeem the property from the
foreclosure sale. In certain other states, this right of redemption applies only
to sale following judicial foreclosure, and not sale pursuant to a non-judicial
power of sale. In most states where the right of redemption is available,
statutory redemption may occur upon payment of the foreclosure purchase price,
accrued interest and taxes. In most states where the right of redemption is
available, statutory redemption may occur upon payment of the foreclosure
purchase price, accrued interest and taxes. In some states the right to redeem
is an equitable right. The effect of a right of redemption is to diminish the
ability of the lender to sell the foreclosed property. The exercise of a right
of redemption would defeat the title of any purchaser at a foreclosure sale, or
of any purchaser from the lender subsequent to judicial foreclosure or sale
under a deed of trust. Consequently, the practical effect of the redemption
right is to force the lender to maintain the property and pay the expense of
ownership until the expiration of the redemption period.
 
    ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS.  Certain
states have imposed statutory restrictions that limit the remedies of a
beneficiary under a deed of trust or a mortgagee under a mortgage relating to a
single family residence. In some states, statutes limit the right of the
beneficiary or mortgagee to obtain a deficiency judgment against the borrower
following foreclosure or sale under a deed of trust. A deficiency judgment is a
personal judgment against the borrower equal in most cases to the difference
between the amount due to the lender and the net amount realized upon the
foreclosure sale.
 
    Some state statutes may require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an attempt
to satisfy the full debt before bringing a personal action against the borrower.
In certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting such security;
however, in some of these states, the lender, following judgment on such
personal action, may be deemed to have elected a remedy and may be precluded
from exercising remedies with respect to the security. Consequently, the
practical effect of the election requirement, when applicable, is that lenders
will usually proceed first against the security rather than bringing a personal
action against the borrower.
 
    Other statutory provisions may limit any deficiency judgment against the
former borrower following a foreclosure sale to the excess of the outstanding
debt over the fair market value of the property at the time of such sale. The
purpose of these statutes is to prevent a beneficiary or a mortgagee from
obtaining a large deficiency judgment against the former borrower as a result of
low or no bids at the foreclosure sale. In some states, exceptions to the
anti-deficiency statutes are provided for in certain instances where the value
of the lender's security has been impaired by acts or omissions of the borrower,
for example, in the event of waste of the property.
 
    In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws,
the federal Soldiers' and Sailors' Civil Relief Act of 1940 and state laws
affording relief to debtors, may interfere with or affect the ability of a
secured mortgage lender to realize upon its security and/or enforce a judgment.
For example, with respect to a Land Home Contract, in a proceeding under the
federal Bankruptcy Code, the court may prevent a lender from foreclosing on the
home, and when a court determines that the value of a home is less than the
principal balance of the loan, the court may reduce the amount of the secured
indebtedness to the value of the home as it exists at the time of the
proceeding, leaving the lender as a general unsecured creditor for the
difference between that value and the amount of outstanding indebtedness. A
bankruptcy court may grant
 
                                      S-69
<PAGE>
the debtor a reasonable time to cure a payment default, reduce the monthly
payments due under such mortgage loan, change the rate of interest and/or alter
the mortgage loan repayment schedule.
 
    The Code provides priority to certain tax liens over the lien of the
mortgage or deed of trust. The laws of some states provide priority to certain
tax liens over the lien mortgage or deed of trust. Numerous federal and some
state consumer protection laws impose substantive requirements upon mortgage
lenders in connection with the origination, servicing and the enforcement of
mortgage loans. These laws include the federal Truth in Lending Act, Real Estate
Settlement Procedures Act, Equal Credit Opportunity, Fair Credit Billing Act,
Fair Credit Reporting Act, and related statutes and regulations. These federal
laws and state laws impose specific statutory liabilities upon lenders who
originate or service mortgage loans and who fail to comply with the provisions
of the law. In some cases, this liability may affect assignees of the Contracts.

                                    RATINGS
 
    It is a condition to the issuance of the Certificates that each Class of
Senior Certificates be rated "Aaa" by Moody's and "AAA" by Fitch, that the Class
M Certificates be rated at least "Aa3" by Moody's and "AA- " by Fitch and that
the Class B-1 Certificates be rated at least "Baa2" by Moody's and "BBB" by
Fitch. A security rating is not a recommendation to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
agency. The security rating of the Offered Certificates should be evaluated
independently of similar security ratings assigned to other kinds of securities.
 
    The ratings assigned by Moody's and Fitch to pass-through certificates
address the likelihood of the receipt by the related certificateholders of their
allocable share of principal and interest on the underlying assets. Moody's and
Fitch ratings take into consideration the credit quality of the related
underlying assets, any credit support arrangements, structural and legal aspects
associated with such certificates, and the extent to which the payment stream on
such underlying assets is adequate to make payments required by such
certificates. Moody's and Fitch ratings on such certificates do not, however,
constitute a statement regarding frequency of prepayments on the underlying
assets or as to whether yield may be adversely affected as a result thereof. An
explanation of the significance of such ratings may be obtained from Moody's
Investors Service, Inc., 99 Church Street, New York, New York 10004, telephone:
(212) 553-0300, and Fitch IBCA, Inc., One State Street Plaza, New York, New York
10004, telephone (212) 908-0500, respectively.
 
    The Sellers have not requested a rating on the Offered Certificates by any
rating agency other than Moody's and Fitch. However, there can be no assurance
as to whether any other rating agency will rate any or all of the Offered
Certificates, or if it did, what rating would be assigned to the Offered
Certificates by any such other rating agency. A rating on any or all of the
Offered Certificates by certain other rating agencies, if assigned at all, may
be lower than the rating assigned to such Certificates by Moody's and Fitch.
 
                                LEGAL INVESTMENT
 
    The Senior and Class M Certificates at the time of issuance will qualify as
"mortgage related securities" under the Secondary Mortgage Market Enhancement
Act of 1984, as amended ("SMMEA") and, as such, will constitute legal
investments for certain types of investors to the extent provided in SMMEA. Such
institutions should consult their own legal advisors in determining whether and
to what extent the Senior Certificates constitute legal investments for such
investors.
 
    Because the Class B-1 Certificates will not, at the time of issuance, be
rated in one of the two highest rating categories of Moody's and Fitch, the
Class B-1 Certificates will not constitute "mortgage related securities" for
purposes of SMMEA. Accordingly, many institutions with legal authority to invest
in more highly rated securities based on first mortgage loans may not be legally
authorized to invest in the Class B-1 Certificates. No representation is made as
to any regulatory requirements or considerations (including without limitation
regulatory capital or permissible investment requirements) applicable to the
purchase of the Class B-1 Certificates by banks, savings and loan associations
or other financial institutions. Such institutions should consult their own
legal advisors in determining whether and to what extent the Offered
Certificates constitute legal investments for such investors. See "Legal
Investment" in the Prospectus.

    In the Underwriting Agreement, the Underwriters have agreed, subject to the

    The Underwriters will reimburse certain expenses of the Sellers.
 
    In connection with the sale of the Offered Certificates, the Underwriters
and other persons participating in the sale may engage in transactions that
stabilize, maintain or otherwise affect the price of the Offered Certificates.
Specifically, the Underwriters may over-allot in connection with the sale,
creating a short position in the Offered Certificates for their own account. To
cover over-allotments or to stabilize the price of the Offered Certificates, the
Underwriters may bid for, and purchase, Offered Certificates in the open market.
Finally, the Underwriters may bid for, and purchase, Offered Certificates in
market making

transactions. These activities may stabilize or maintain the market price of the
Offered Certificates above market levels that may otherwise prevail. The
Underwriters are not required to engage in these activities and may end any of
these activities at any time.
 
                                USE OF PROCEEDS
 
    Substantially all of the net proceeds to be received from the sale of the
Offered Certificates will be used by the Sellers for general corporate purposes,
including the purchase of the Contracts and the payment of other expenses
connected with pooling the Contracts and issuing the Offered Certificates.

         GLOBAL CLEARANCE, SETTLEMENT AND TAX DOCUMENTATION PROCEDURES
 
    Except in certain limited circumstances, the globally offered BankAmerica
Manufactured Housing Contract Trust V Senior/Subordinate Pass-Through
Certificates, Series 1998-2 (the "Global Securities") will be available only in
book-entry form. Investors in the Global Securities may hold such Global
Securities through any of The Depository Trust Company ("DTC"), Cedel or
Euroclear. The Global Securities will be tradable as home market instruments in
both the European and U.S. domestic markets. Initial settlement and all
secondary trades will settle in same-day funds.
 
    Secondary market trading between investors holding Global Securities through
Cedel and Euroclear will be conducted in the ordinary way in accordance with
their normal rules and operating procedures and in accordance with conventional
eurobond practice (i.e., seven calendar day settlement).
 
    Secondary market trading between investors holding Global Securities through
DTC will be conducted according to the rules and procedures applicable to U.S.
corporate debt obligations.
 
    Secondary cross-market trading between Cedel or Euroclear and DTC
Participants holding Certificates will be effected on a delivery-against-payment
basis through the respective Depositaries of Cedel and Euroclear (in such
capacity) and as DTC Participants.
 
    Non-U.S. holders (as described below) of Global Securities will be subject
to U.S. withholding taxes unless such holders meet certain requirements and
deliver appropriate U.S. tax documents to the securities clearing organizations
or their participants.
 
INITIAL SETTLEMENT
 
    All Global Securities will be held in book-entry form by DTC in the name of
Cede & Co. as nominee of DTC. Investors' interests in the Global Securities will
be represented through financial institutions noting on their behalf as direct
and indirect Participants in DTC. As a result, Cedel and Euroclear will hold
positions on behalf of their participants through their respective Depositaries,
which in turn will hold such positions in accounts as DTC Participants.
 
    Investors electing to hold their Global Securities through DTC will follow
the settlement practices applicable conventional eurobonds, except that there
will be no temporary global security and no "lock-up" or restricted period.
Investors securities custody accounts will be credited with their holdings
against payment in same-day funds on the settlement date.
 
    Investors electing to hold their Global Securities through Cedel or
Euroclear accounts will follow the settlement procedures applicable to
conventional eurobonds, except that there will be no temporary global security
and no "lock-up" restricted period. Global Securities will be credited to the
securities custody accounts on the settlement date against payment same-day
funds.
 
SECONDARY MARKET TRADING
 
    Since the purchaser determines the place of delivery, it is important to
establish at the time of the trade where both the purchaser's and seller's
accounts are located to ensure that settlement can be made on the desired value
date.
 
    TRADING BETWEEN DTC PARTICIPANTS.  Secondary market trading between DTC
Participants will be settled using the procedures applicable to prior
manufactured housing contract pass-through certificates issues in same-day
funds.
 
                                      I-1
<PAGE>
    TRADING BETWEEN CEDEL AND/OR EUROCLEAR PARTICIPANTS.  Secondary market
trading between Cedel Participants or Euroclear Participants will be settled
using the procedures applicable to conventional eurobonds in same-day funds.
 
    TRADING BETWEEN DTC SELLER AND CEDEL OR EUROCLEAR PURCHASER.  When Global
Securities are to be transferred from the account of a DTC Participant to the
account of a Cedel Participant or a Euroclear Participant, the purchaser will
send instructions to Cedel or Euroclear through a Cedel Participant or Euroclear
Participant at least one business day prior to settlement. Cedel or Euroclear
will instruct the respective Depositary, as the case may be, to receive the
Global Securities against payment. Payment will include interest accrued on the
Global Securities from and including the last coupon payment date to and
excluding the settlement date, on the basis of the actual number of days in such
accrual period and a year assumed to consist of 360 days. For transactions
settling on the 31st of the month, payment will include interest accrued to and
excluding the first day of the following month. Payment will then be made by the
respective Depositary of the DTC Participant's account against delivery of the
Global Securities. After settlement has been completed, the Global Securities
will be credited to the respective clearing system and by the clearing system,
in accordance with its usual procedures, to the Cedel Participant's or Euroclear
Participant's account. The securities credit will appear the next day (European
time) and the cash debt will be back-valued to, and the interest on the Global
Securities will accrue from, the value date (which would be the preceding day
when settlement occurred in New York). If settlement is not completed on the
intended value date (i.e., the trade fails), the Cedel or Euroclear cash debt
will be valued instead as of the actual settlement date.
 
    Cedel Participants and Euroclear Participants will need to make available to
the respective clearing systems the funds necessary to process same-day funds
settlement. The most direct means of doing so is to preposition funds for
settlement, either from cash on hand or existing lines of credit, as they would
for any settlement occurring within Cedel or Euroclear. Under this approach,
they may take on credit exposure to Cedel or Euroclear until the Global
Securities are credited to their accounts one day later.
 
    As an alternative, if Cedel or Euroclear has extended a line of credit to
them, Cedel Participants or Euroclear Participants can elect not to preposition
funds and allow that credit line to be drawn upon the finance settlement. Under
this procedure, Cedel Participants or Euroclear Participants purchasing Global
Securities would incur overdraft charges for one day, assuming they cleared the
overdraft when the Global Securities were credited to their accounts. However,
interest on the Global Securities would accrue from the value date. Therefore,
in many cases the investment income on the Global Securities earned during that
one-day period may substantially reduce or offset the amount of such overdraft
charges, although this result will depend on each Cedel Participant's or
Euroclear Participant's particular cost of funds.
 
    Since the settlement is taking place during New York business hours, DTC
Participants can employ their usual procedures for sending Global Securities to
the respective European Depositary for the benefit of Cedel Participants or
Euroclear Participants. The sale proceeds will be available to the DTC seller on
the settlement date. Thus, to the DTC Participants a cross-market transaction
will settle no differently than a trade between two DTC Participants.
 
    TRADING BETWEEN CEDEL OR EUROCLEAR SELLER AND DTC PURCHASER.  Due to time
zone differences in their favor, Cedel Participants and Euroclear Participants
may employ their customary procedures for transactions in which Global
Securities are to be transferred by the respective clearing system, through the
respective Depositary, to a DTC Participant. The seller will send instructions
to Cedel Participants or Euroclear Participants through a Cedel Participant or
Euroclear Participant at least one business day prior to settlement. In these
cases Cedel or Euroclear will instruct the respective Depositary, as
appropriate, to deliver the Global Securities to the DTC Participant's account
against payment. Payment will include interest accrued on the Global Securities
from and including the last coupon payment to and excluding the settlement date
on the basis of either the actual number of days in such accrual period and a
year assumed to consist of 360 days or a 360-day year of twelve 30-day months,
as applicable to the related class of
 
                                      I-2
<PAGE>
Global Securities. For transactions settling on the 31st of the month, payment
will include interest accrued to and excluding the first day of the following
month. The payment will then be reflected in the account of the Cedel
Participant or Euroclear Participant the following day, and receipt of the cash
proceeds in the Cedel Participant's or Euroclear Participant's account would be
back-valued to the value date (which would be the preceding day, when settlement
occurred in New York). Should the Cedel Participant or Euroclear Participant
have a line of credit with its respective clearing system and elect to be in
debt in anticipation of receipt of the sale proceeds in its account, the
back-valuation will extinguish any overdraft incurred over that one-day period.
If settlement is not completed on the intended value date (i.e., the trade
fails), receipt of the cash proceeds in the Cedel Participant's or Euroclear
Participant's account would instead be valued as of the actual settlement date.
 
    Finally, day traders that use Cedel or Euroclear and that purchase Global
Securities from DTC Participants for delivery to Cedel Participants or Euroclear
Participants should note that these trades would automatically fail on the sale
side unless affirmative action were taken. At least three techniques should be
readily available to eliminate this potential problem:
 
    (a) borrowing through Cedel or Euroclear for one day (until the purchase
side of the day trade is reflected in their Cedel or Euroclear accounts) in
accordance with the clearing system's customary procedures;
 
    (b) borrowing the Global Securities in the U.S. from a DTC Participant no
later than one day prior to settlement, which would give the Global Securities
sufficient time to be reflected in their Cedel or Euroclear account in order to
settle the sale side of the trade; or
 
    (c) staggering the value dates for the buy and sell sides of the trade so
that the value date for the purchase from the DTC Participant is at least one
day prior to the value date for the sale to the Cedel Participant or Euroclear
Participant.
 
CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS
 
    A beneficial owner of Global Securities holding securities through Cedel or
Euroclear (or through DTC if the holder has an address outside the U.S.) will be
subject to the 30% U.S. withholding tax that generally applies to payments of
interest (including original issue discount) on registered debt issued by U.S.
Persons, unless, under currently applicable laws, (i) each clearing system, bank
or other financial institution that holds customers' securities in the ordinary
course of its trade or business in the chain of intermediaries between such
beneficial owner and the U.S. entity required to withhold tax complies with
applicable certification requirements and (ii) such beneficial owner takes one
of the following steps to obtain an exemption or reduced tax rate:
 
    EXEMPTION FOR NON-U.S. PERSONS (FORM W-8).  Beneficial owners of Global
Securities that are non-U.S. Persons can obtain a complete exemption from the
withholding tax by filing a signed Form W-8 (Certificate of Foreign Status). If
the information shown on Form W-8 changes, a new Form W-8 must be filed within
30 days of such change.
 
    EXEMPTION FOR NON-U.S. PERSONS WITH EFFECTIVELY CONNECTED INCOME (FORM
4224).  A non-U.S. Person, including a non-U.S. corporation or bank with a U.S.
branch, for which the interest income is effectively connected with its conduct
of a trade or business in the United States, can obtain an exemption from the
withholding tax by filing Form 4224 (Exemption from Withholding of Tax on Income
Effectively Connected with the Conduct of a Trade or Business in the United
States).
 
    EXEMPTION OR REDUCED RATE FOR NON-U.S. PERSONS RESIDENT IN TREATY COUNTRIES
(FORM 1001).  Non-U.S. Persons that are Certificate Owners residing in a country
that has a tax treaty with the United States can obtain an exemption or reduced
tax rate (depending on the treaty terms) by filing Form 1001 (Ownership,
 
                                      I-3
<PAGE>
Exemption or Reduced Rate Certificate). If the treaty provides only for a
reduced rate, withholding tax will be imposed at that rate unless the filer
alternatively files Form W-8. Form 1001 may be filed by the Certificate Owner or
his agent.
 
    EXEMPTION FOR U.S. PERSONS (FORM W-9).  U.S. Persons can obtain a complete
exemption from the withholding tax by filing Form W-9 (Payer's Request for
Taxpayer Identification Number and Certification).
 
    U.S. FEDERAL INCOME TAX REPORTING PROCEDURE.  The Certificate Owner of a
Global Security or, in the case of a Form 1001 or a Form 4224 filer, his agent,
files by submitting the appropriate form to the person through whom it holds
(the clearing agency, in the case of persons holding directly on the books of
the clearing agency). Form W-8 and Form 1001 are effective for three calendar
years and Form 4224 is effective for one calendar year.
 
    The term "U.S. Person" means (i) a citizen or resident of the United States,
(ii) a corporation or partnership organized in or under the laws of the United
States or any political subdivision thereof or (iii) an estate or trust the
income of which is includible in gross income for United States tax purposes,
regardless of its source. This summary does not deal with all aspects of U.S.
Federal income tax withholding that may be relevant to foreign holders of the
Global Securities. Investors are advised to consult their own tax advisors for
specific tax advice concerning their holding and disposing of the Global
Securities. Further, the U.S. Treasury Department has recently finalized new
regulations that will revise some aspects of the current system for withholding
on amounts paid to foreign persons. Under these regulations, interest or OID
paid to a nonresident alien would continue to be exempt from U.S. withholding
taxes (including backup withholding) provided that the holder complies with the
new certification procedures.

discussed below). Bank of America, FSB, acting through its division, BankAmerica
Housing Services, will act as the servicer of the Contracts in each Trust Fund
(together with any successor servicer appointed as described herein, the
"Servicer").
 
    The Contracts comprising each Contract Pool will be conveyed to the relevant
Trust Fund by the applicable Sellers. Each Contract will have been either (i)
originated or purchased by Bank of America, Bank of America, FSB, acting through
its division, BankAmerica Housing Services, or by Security Pacific Financial
Services of California, Inc. ("SPFSC"), a wholly-owned subsidiary of Bank of
America, in each case on an individual basis in the ordinary course of its

thereof, in bulk from other lenders or finance companies (including from
affiliates of the Sellers), from governmental agencies or instrumentalities or
from other entities. Interests in each Trust Fund will be evidenced by a
separate Series of Certificates. SPFSC will not be conveying any Contracts to
any Trust Fund. Any Contracts purchased on an individual basis or in bulk by
SPFSC will be sold by it to Bank of America, and conveyed by Bank of America to
the Trustee of a Trust Fund immediately before the issuance of Certificates
evidencing interests in such Contracts.
 
    If a Series of Certificates is comprised of more than one Class, the related
Prospectus Supplement will set forth the interest in the applicable Trust Fund
represented by each Class sold hereunder. The timing of distributions of
principal or of interest or of both to the holders of Certificates of such
Classes may be on a sequential, pro-rata or other basis as specified in the
related Prospectus Supplement. In addition, if specified in the related
Prospectus Supplement, the rights of the holders of the Certificates of one or
more Classes of a multiple-Class Series to receive distributions with respect to
some or all of the assets of the related Trust Fund may be subordinate to such
rights of the holders of the Certificates of one or more other Classes.
 
    Neither Bank of America nor Bank of America, FSB nor any of their affiliates
will have any obligations with respect to any Series of Certificates except, in
the case of the Sellers, for obligations arising from certain representations
and warranties of Bank of America and Bank of America, FSB, as the case may be,
with respect to the Contracts sold by it in the related Contract Pool and, in
the case of Bank of America, FSB, for certain contractual servicing obligations,
each as further described herein. See "Risk Factors--No Recourse" herein.
 
    To the extent specified in the related Prospectus Supplement, the holders of
the Certificates of any Series, or of one or more Classes within a Series, may
be entitled to the benefit of overcollateralization or subordination of one or
more Classes of Certificates within such Series, one or more spread accounts or
other reserve funds, one or more letters of credit, one or more surety bonds or
other credit facilities and/ or one or more certificate purchase agreements or
other liquidity facilities. See "Credit and Liquidity Enhancement" herein and
the related Prospectus Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Certificates of a Series or of any Class within a Series will be issuable in the
form of one or more global certificates represented by book-entries on the
records of a depository or participating members thereof. See "Reports to
Certificateholders," "Risk Factors," and "Description of the
Certificates--Global Certificates" herein and the related Prospectus Supplement.
 
    There will have been no public market for any Certificates sold hereunder
prior to the offering thereof and there is no assurance that any such market
will develop. The Underwriters named in the Prospectus Supplement relating to a
Series may from time to time buy and sell Certificates of such Series, but there
can be no assurance that an active secondary market therefor will develop, and
there is no assurance that any such market, if established, will continue. See
"Risk Factors" herein.

will file with the Commission such periodic reports with respect to the Trust
Fund as are required under the Exchange Act, and the rules and regulations of
the Commission thereunder. If the number of Certificateholders of record is
below 300, the Certificates may cease to be subject to the periodic reporting

                                    accordance with a formula described in the related
                                    Prospectus Supplement, and, unless otherwise specified
                                    in such Prospectus Supplement, distributions allocable
                                    to a Class of Certificates will be applied first to
                                    interest, if any, and second to principal, if any. To
                                    the extent specified in the related Prospectus
                                    Supplement, the rights of the holders of the
                                    Certificates of one or more Classes of a multiple-Class
                                    Series to receive distributions of principal or of
                                    interest or both from amounts collected on the Contracts
                                    may be subordinate to such rights of the holders of
                                    Certificates of one or more other Classes. See "Credit
                                    and Liquidity Enhancement" herein and the applicable
                                    Prospectus Supplement.
 
A. Distributions of Principal.....  If the Certificates of a Class entitle the holders
                                    thereof to distributions of principal, the related
                                    Prospectus Supplement will specify an initial aggregate
                                    principal balance for the Certificates of the Class (the
                                    related "Certificate Balance") and a method of computing
                                    the amount of principal, if any, to be distributed to
                                    the holders of such Certificates on each Distribution
                                    Date. Unless otherwise specified in the related
                                    Prospectus Supplement, principal distributions for the
                                    Certificates of a Class will be computed on the basis of
                                    a formula which, on each Distribution Date, allocates
                                    all or a portion of the Total Regular Principal Amount
                                    relating to that Distribution Date to the Certificates
                                    of that Class. The "Total Regular Principal Amount" is
                                    the total amount by which the aggregate outstanding
                                    principal balance of the Contracts in the related
                                    Contract Pool is reduced during one or more collection
                                    periods prior to the Distribution Date designated in
                                    such Prospectus Supplement (each, a "Collection
                                    Period"). Such reduction may occur as a result of
                                    actuarially predetermined scheduled principal
                                    reductions, receipt of principal prepayments,
                                    liquidation of Contracts, losses on Contracts and
                                    repurchases of Contracts under certain conditions, the
                                    failure of a third party credit support provider, if
                                    any, to make a required payment, or a combination of the
                                    foregoing events. See "The Contract Pools," "Description

                                    If, due to liquidation losses or other circumstances
                                    adversely affecting the collections on the underlying

                                    Enhancement" herein. If specified in the applicable
                                    Prospectus Supplement, the Certificate Balance of the
                                    Certificates of a Class will be reduced on each
                                    Distribution Date by the full amount of the portion of

                                    Class even if, due to deficient Contract collections, a
                                    full distribution thereof is not made.
 
                                    The applicable distribution formula for each Class of a
                                    multiple-Class Series may allocate the Total Regular

                                    Class to receive on certain Distribution Dates,
                                    distributions of Regular Principal from particular
                                    sources of credit support upon the occurrence of certain
                                    losses or delinquencies, even if the holders of the
                                    Certificates of such Class would not have been entitled
                                    to receive principal distributions on such Distribution
                                    Dates from amounts collected on the underlying Contracts
                                    in the absence of such losses or delinquencies.
 
                                    If specified in the applicable Prospectus Supplement,
                                    the Certificates of a Class may entitle the holders
                                    thereof to special principal distributions on particular

                                    Supplement. The Certificates of a Class having an
                                    initial Certificate Balance may entitle the holders
                                    thereof to distributions of Regular Principal only, to
                                    distributions of Regular Principal and to Special
                                    Principal Distributions or to Special Principal
                                    Distributions only. However, unless otherwise stated in
                                    the related Prospectus Supplement, the Certificates of a
                                    Class will not entitle the holders thereof to aggregate
                                    principal distributions in excess of the initial
                                    Certificate Balance for such Class.
 
B. Distributions of Interest......  The distribution formula for a Class of Certificates
                                    having an initial Certificate Balance may, but need not,
                                    also specify a method of computing the interest, if any,
                                    to be distributed on specified Distribution Dates (which
                                    may include all or less than all of the Distribution
                                    Dates) to the holders of the Certificates of such Class.
                                    Such interest may be equal, subject to such adjustments
                                    as may be described in the related Prospectus Supple-
                                    ment, to a specified number of days' interest on the
                                    applicable Certificate Balance (before giving effect to
                                    any reduction thereof on such Distribution Date),
                                    calculated at a rate (the "Pass-Through Rate") specified
                                    in the related Prospectus Supplement. The Pass-Through
                                    Rate may be fixed or variable, and, if specified in the
                                    related Prospectus Supplement, may shift from a variable
                                    rate to a fixed rate under the conditions specified in
                                    such Prospectus Supplement. See "Description of the

                                    that might be applicable to a Class of Certificates.
                                    Alternatively, such interest may be equal to all or a
                                    portion (which portion will be determined as described
                                    in the related Prospectus Supplement) of the interest
                                    due on the related Contracts during one or more
                                    Collection Periods occurring prior to such Distribution
                                    Date. Classes of Certificates that do not entitle the
                                    holders thereof to receive distributions of principal
                                    may nevertheless entitle such holders to receive inter-
                                    est distributions calculated on this basis. If, due to
                                    liquidation losses or other circumstances adversely
                                    affecting the collections on the underlying Contract

                                    interest computed as described above, the deficiency may
                                    be made up from other sources, but only to the extent,
                                    if any, specified in the related Prospectus Supplement.

C. Residual Interests.............  If specified in the related Prospectus Supplement, a
                                    Class of Certificates in any Series may evidence a

                                    liquidation losses or other events resulting in
                                    deficient Contract collections.
 
                                    In addition, if specified in the related Prospectus
                                    Supplement, certain or all Certificates evidencing
                                    Residual Interests may also entitle the holders thereof
                                    to receive additional distributions of assets of the
                                    related Trust Fund, to the extent any such assets remain
                                    after being applied to make distributions to the holders
                                    of other interests in the Trust Fund (or to pay expenses
                                    of the Trust Fund). The Certificates evidencing a
                                    Residual Interest may entitle the holders thereof to
                                    distributions at various times throughout the life of
                                    the related Trust Fund or only upon termination of the
                                    Trust Fund, all as more fully set forth in the related
                                    Prospectus Supplement. If an election is made to treat
                                    the related Trust Fund as a REMIC, the holders of a
                                    Residual Interest in such Trust Fund will be subject to
                                    federal income taxation with respect to their ownership
                                    of such Residual Interest as described herein under
                                    "Certain Federal Income Tax Consequences--REMIC
                                    Certificates--D. Taxation of Residual Certificates."
 
Global Certificates...............  Unless otherwise specified in the related Prospectus
                                    Supplement, the Certificates of a Series, or of one or
                                    more Classes within a Series, will be issuable in the
                                    form of one or more global certificates (each, a "Global
                                    Certificate") to be held by Cede & Co. ("Cede"), as
                                    nominee of The Depository Trust Company ("DTC"), on
                                    behalf of the beneficial owners (the "Certificate
                                    Owners") of the Certificates, as described herein under
                                    "Description of the Certificates--Global Certificates."
                                    If some or all of the Certificates of a Series are
                                    issued in the form of one or more Global Certificates,
                                    certain monthly and annual reports prepared by the
                                    Servicer under the related Agreement will be sent on
                                    behalf of the related Trust Fund to Cede and not to the
                                    Certificate Owners, as described in "Reports to Certifi-
                                    cateholders" above.
 
Credit and Liquidity
  Enhancement.....................  The extent, if any, to which a Class of Certificates in
                                    any Series may be entitled to the benefit of one or more
                                    forms of credit and liquidity enhancement by means of
                                    overcollateralization or subordination of one or more

                                    Supplement.
 
Advances..........................  The extent, if any, to which the Servicer will be
                                    required to make advances of delinquent scheduled
                                    payments on the Contracts in a Contract Pool will be
                                    described in the related Prospectus Supplement.
 
Optional Termination and Termina-
  tion Auction....................  The Servicer has the option to purchase from the Trust
                                    Fund all Contracts then outstanding and all other
                                    property in the Trust Fund on any Distribution Date
                                    after the First Distribution Date if, among other
                                    conditions, the Pool Scheduled Principal Balance is less
                                    than 10% of the Cut-off Date Pool Principal Balance. See
                                    "Description of the Certificates--Optional Termination
                                    and Termination Auction" herein. During that period, the
                                    Servicer also may direct the Trustee to conduct a
                                    Termination Auction for the sale of all Contracts then
                                    outstanding in the Trust Fund, and, in any event, if the
                                    Servicer has not exercised the option call within 90
                                    days of the first Distribution Date when the Pool
                                    Scheduled Principal Balance is less than 10% of the
                                    Cut-off Date Pool Principal Balance, the Servicer shall
                                    direct the Trustee to conduct a Termination Auction. See
                                    "Description of the Certificates--Optional Termination
                                    and Termination Auction" herein. Any early termination
                                    of the Trust Fund and early retirement of the
                                    Certificates that results from the Servicer's exercise
                                    of the option call or a successful Termination Auction
                                    may have an effect on an investor's yield on such
                                    Certificates. See "Prepayment and Yield Considerations"
                                    herein and in the Prospectus Supplement.
 
Federal Income Tax Consequences...  The federal income tax consequences of the purchase,
                                    ownership and disposition of the Certificates in any
                                    Series will depend on, among other factors, whether an
                                    election is made to treat the related Trust Fund as a
                                    REMIC under the provisions of the Internal Revenue Code
                                    of 1986, as amended (the "Code"). See "Certain Federal
                                    Income Tax Consequences--REMIC Certificates" herein for

                                    the purchase, ownership and disposition of the Cer-
                                    tificates in any Series if such an election is made. See

                                    of the Certificates in any Series if such an election is
                                    not made.
 
ERISA Considerations..............  A fiduciary of any employee benefit or other plan
                                    subject to the Employee Retirement Income Security Act
                                    of 1974, as amended ("ERISA"), or Section 4975 of the
                                    Code should carefully review with its own legal advisors
                                    whether the purchase or holding of Certificates could
                                    give rise to a transaction that is prohibited or
                                    otherwise impermissible under ERISA or the Code. See

                                    Supplement. If specified in the related Prospectus
                                    Supplement, certain Certificates sold hereunder will not
                                    be transferable to certain benefit plan investors except
                                    under the conditions set forth in such Prospectus
                                    Supplement.
 
Legal Investment..................  Unless otherwise indicated in the applicable Prospectus
                                    Supplement, any Certificates offered hereby that are
                                    rated by at least one nationally recognized statistical
                                    rating organization in one of its two highest rating
                                    categories will generally constitute "mortgage related
                                    securities" under the Secondary Mortgage Market
                                    Enhancement Act of 1984, as amended ("SMMEA") and, as
                                    such, would be "legal investments" for certain types of
                                    institutional investors to the extent provided in SMMEA.
                                    Certain state laws have overridden SMMEA and, therefore,
                                    institutional investors should review with their own
                                    legal advisors whether such Certificates would
                                    constitute a legal investment. In addition, some Classes
                                    of Certificates offered hereby may not be rated in one
                                    of the two highest rating categories and thus would not
                                    constitute "mortgage related securities." See "Legal
                                    Investment" herein and in the related Prospectus
                                    Supplement.
 
Rating............................  It is a condition to the issuance of each Class of
                                    Certificates sold under this Prospectus that it be rated
                                    at the time of issuance by at least one nationally
                                    recognized statistical rating organization in one of its
                                    four highest rating categories. A security rating is not
                                    a recommendation to buy, sell or hold securities and may
                                    be subject to revision or withdrawal at any time by the
                                    assigning rating agency. The security rating of any
                                    Class of Certificates should be evaluated independently
                                    of similar security ratings assigned to other kinds of
                                    securities, including Certificates in the same Series or
                                    Certificates of other Series sold under this Pro-
                                    spectus.
 
                                    Ratings on manufactured housing contract pass-through
                                    certificates address the likelihood of the receipt by
                                    certificateholders of their allocable share of principal
                                    and interest on the underlying manufactured housing
                                    contract assets. These ratings address structural and
                                    legal aspects associated with such certificates, the
                                    extent to which the payment stream on such underlying
                                    assets is adequate to make payments required by such
                                    certificates and the credit quality of the credit
                                    enhancer, if any. Ratings on the Certificates do not,
                                    however, constitute a statement regarding the likelihood
                                    of principal prepayments by Obligors under the Contracts
                                    in the related Contract Pool, the degree by which
                                    prepayments made by such Obligors might differ from
                                    those originally anticipated or whether the yield
                                    originally anticipated by investors of any Series of
                                    Certificates may be adversely affected as a result of
                                    such prepayments. As a result, investors of any Series
                                    of Certificates might suffer a lower than anticipated
                                    yield. See "Rating" herein and in the related Prospectus

                                  RISK FACTORS
 
    Prospective purchasers of Certificates should consider, among other things,
the following factors in connection with the purchase of Certificates. This
Prospectus contains forward-looking statements within the meaning of Section 27A
of the Securities Act and Section 21E of the Securities Exchange Act. Actual
results could differ materially from those projected in the forward-looking
statements as a result of the risk factors set forth below and elsewhere in this
Prospectus.
 
    LIMITED LIQUIDITY.  There can be no assurance that a secondary market will
develop for Certificates or, if it does develop, that it will provide the
holders of Certificates with liquidity of investment or that it will remain for
the term of such Certificates.
 
    BOOK-ENTRY FORM.  To the extent any Certificate is represented by a Global
Certificate, the issuance of such Certificates in book-entry form may reduce the
liquidity of such Certificates in the secondary trading market since investors
may be unwilling to purchase Certificates for which they cannot obtain physical
certificates. See "Description of the Certificates--Global Certificates" herein.
 
    PREVAILING ECONOMIC CONDITIONS.  An investment in Certificates may be
affected by, among other things, a downturn in national, regional or local
economic conditions. The geographic location of the Manufactured Homes in any
Contract Pool at origination of the related Contract will be set forth in the
related Prospectus Supplement under "The Contract Pool." Regional and local
economic conditions are often volatile and, historically, regional and local
economic conditions, as well as national economic conditions, have affected the
delinquency, loan loss and repossession experience of manufactured housing
installment sales contracts and/or installment loan contracts (hereinafter
generally referred to as "contracts" or "manufactured housing contracts").
Sufficiently high delinquencies and liquidation losses on the Contracts in any
contract pool will have the effect of reducing, and possibly eliminating, the
protection against loss afforded by any credit enhancement supporting any Class
of the related Certificates. If such protection is eliminated with respect to a
Class of Certificates, the holders of such Certificates will bear all risk of
loss on the related Contracts and will have to rely on the value of the related
Manufactured Homes for recovery of the outstanding principal of and unpaid
interest on any defaulted Contracts in the related Contract Pool. See "Credit
and Liquidity Enhancement" herein and the related Prospectus Supplement.
 
    LIQUIDATION LOSSES AND CREDIT RISK.  Manufactured housing generally
depreciates in value, regardless of its location. Thus, Certificateholders
should expect that, as a general matter, the market value of any Manufactured
Home will be lower than the outstanding balance of the related Contract. To the
extent that the Servicer is required to repossess Manufactured Homes because of
owner defaults under the Contracts, liquidation losses will likely occur. The
primary protection of Certificateholders against these liquidation losses comes
from three sources: first, the amount (the "Excess Interest"), if any, by which
the interest collected on nondefaulted Contracts during a Collection Period
exceeds interest distributions due to the holders of the Regular Certificates
and the Monthly Servicing Fee; second, any Credit Facility or Reserve Fund that
may support one or more Classes of Certificates, and third, as to the holders of
Senior Certificates, the subordination in interest of the junior Classes of
Certificates. The amount of Excess Interest can vary from Contract Pool to
Contract Pool, and will be reduced if interest-only Certificates are issued. If
the liquidation losses exceed the amount of Excess Interest and any Credit
Facility or Reserve Fund, the payments on Certificates will be delayed and
losses are likely to occur that will be borne by the holders of the
Certificates. To the extent that the Certificates have been designated as senior
or subordinate, the most junior certificates would be the first to bear these
delays or losses. See "The Contract Pools" and "Credit and Liquidity
Enhancement" herein and in the related Prospectus Supplement.
 
    NO RECOURSE.  Neither Bank of America nor Bank of America, FSB nor any of
their affiliates will have any obligations with respect to any Series of
Certificates except, in the case of the Sellers, for obligations arising from
certain representations and warranties of Bank of America and Bank of America,
 
                                       12
<PAGE>
FSB, as the case may be, with respect to the Contracts sold by it in the related
Contract Pool, and, in the case of Bank of America, FSB, for certain contractual
servicing obligations, each as further described herein. In all other respects,
the purchase of any Certificate will be without recourse unless the related
Prospectus Supplement (i) specifies that some or all of the Contracts evidenced
by such Certificate are partially guaranteed by the Veterans Administration or
partially insured by the Federal Housing Administration, or (ii) describes one
or more forms of credit or liquidity enhancement supporting distributions on the
related Certificates. SUBJECT ONLY TO THE FOREGOING EXCEPTIONS, PROCEEDS FROM
THE ASSETS IN THE RELATED TRUST FUND WILL CONSTITUTE THE ONLY SOURCE OF FUNDS
FOR PAYMENT ON THE CERTIFICATES OF THE RELATED SERIES. THE CERTIFICATES WILL NOT
REPRESENT INTERESTS IN OR OBLIGATIONS OF BANK OF AMERICA, BANK OF AMERICA, FSB,
THEIR PARENT CORPORATION, BANKAMERICA CORPORATION, OR ANY AFFILIATE THEREOF, AND
NEITHER THE CERTIFICATES NOR THE UNDERLYING CONTRACTS OR ANY COLLECTIONS THEREON
WILL BE INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR BY
ANY OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY.
 
    SECURITY INTERESTS OF THE TRUST FUND IN THE MANUFACTURED HOMES.  On the date
of initial issuance of Certificates in any Series, Bank of America or Bank of
America, FSB or both will convey the related Contracts to the related Trust
Fund. Bank of America, FSB, through its division, BankAmerica Housing Services,
as Servicer, will obtain and maintain physical possession of the Contract
documents as custodian and agent for the related Trustee. Each Contract is
secured by a security interest in a Manufactured Home and, in the case of Land
Home Contracts or Land-in-Lieu Contracts (both as defined herein), the real
estate on which the related Manufactured Home is located. Perfection of security
interests in the Manufactured Homes and enforcement of rights to realize upon
the value of the Manufactured Homes as collateral for the Contracts are subject
to a number of federal and state laws, including the Uniform Commercial Code
(the "UCC") as adopted in the states in which the Manufactured Homes are located
and such states' certificate of title statutes, and, in the case of Land Home
Contracts or Land-in-Lieu Contracts, their real estate laws. Under such federal
and state laws, a number of factors may limit the ability of a holder of a
perfected security interest in Manufactured Homes to realize upon such
Manufactured Homes or may limit the amount realized to less than the amount due
under the related Contract. See "Certain Legal Aspects of the
Contracts--Security Interests in the Manufactured Homes" and "Land Home and
Land-in-Lieu Contracts" herein.
 
    Unless otherwise specified in the related Prospectus Supplement, the
certificates of title for the Manufactured Homes (including Manufactured Homes
securing Contracts which are purchased by SPFSC and then conveyed by Bank of
America to the related Trust Fund) will show "Security Pacific Financial
Services, a Division of Bank of America, FSB" (the name under which the
BankAmerica Housing Services division of Bank of America, FSB conducted its
business from approximately February 1993 to February 1994), "Security Pacific
Housing Services, a Division of Bank of America, FSB" (the name under which the
BankAmerica Housing Services division of Bank of America, FSB was conducted its
business from approximately February 1994 to June 1995), "Bank of America, FSB,"
or "BankAmerica Housing Services, a division of Bank of America, FSB" as the
lienholder; the UCC financing statements, where applicable, will show Bank of
America, FSB (under one of the foregoing names) as secured party. Because of the
expense and administrative inconvenience involved, Bank of America, FSB will not
amend the certificates of title to change the lienholder specified therein to
the relevant Trustee at the time Contracts are conveyed to a Trust Fund, and
will not execute any transfer instrument (including, among other instruments,
UCC-3 assignments) relating to any Manufactured Home in favor of the relevant
Trustee or deliver any certificate of title to such Trustee or note thereon such
Trustee's interest. Similarly, Bank of America, FSB will not record an
assignment to the Trustee of the mortgage or deed of trust securing each Land
Home or Land-in-Lieu Contract. In some states, in the absence of such an
amendment, notation, execution, delivery or recordation of assignment, the
assignment to the Trustee of the security interest in the Manufactured Homes, or
the mortgage or deed of trust securing a Land Home Contract, may not be
 
                                       13
<PAGE>
effective or such security interest may not be perfected. If any otherwise
effectively assigned security interest in favor of the Trustee is not perfected,
such assignment of the security interest to the Trustee may not be effective
against creditors of Bank of America, FSB, which continues to be specified as
lienholder on any certificate of title or as secured party on any UCC filing, or
against a receiver or conservator of Bank of America, FSB. See "Description of
the Certificates--Conveyance of Contracts" in the applicable Prospectus
Supplement for a description of certain limited circumstances under which Bank
of America, FSB or Bank of America, as the case may be, will be obligated to
repurchase, or at its option substitute another contract for, a Contract sold by
it if, as a result of the failure by Bank of America, FSB to take any action
described above in this paragraph with respect to the related Manufactured Home,
the Trustee does not have a perfected first-priority security interest in such
Manufactured Home or real property, if any.
 
    FEDERAL AND STATE CONSUMER PROTECTION LAWS.  Numerous federal and state
consumer protection laws could adversely affect the interest of any Trust Fund
in the Contracts comprising the related Contract Pool. For example, as described
herein under "Certain Legal Aspects of the Contracts--Consumer Protection Laws,"
the Soldiers' and Sailors' Civil Relief Act of 1940, as amended (the "Relief
Act") could, under certain circumstances, cap the amount of interest that may be
charged on certain Contracts at 6% per annum and may hinder the ability of the
Servicer to foreclose on such Contracts in a timely fashion. In addition, other
federal and state consumer protection laws impose requirements on lending under
installment sales contracts and installment loan agreements such as the
Contracts, and the failure by the lender or seller of goods to comply with such
requirements could give rise to liabilities of assignees for amounts due under
such agreements and the right of set-off against claims by such assignees. These
laws could apply to any Trust Fund as assignee of the related Contracts.
Pursuant to each Agreement, Bank of America, FSB or Bank of America or both of
them, as the case may be, will represent and warrant that each Contract sold by
it complies with all requirements of law. To the extent described in the
applicable Prospectus Supplement under "Description of Certificates--Conveyance
of Contracts," a breach of any such representation or warranty that materially
and adversely affects the related Trust Fund's interest in a Contract will
create an obligation by Bank of America, FSB or Bank of America, as the case may
be, to repurchase, or at its option substitute another contract for, such
Contract, unless such breach is cured within the time period specified in the
related Agreement. Neither Bank of America, FSB nor Bank of America will have
any obligation to repurchase any Contract because of limitations imposed under
the Relief Act, however.
 
    PREPAYMENT CONSIDERATIONS.  The prepayment experience on the Contracts
underlying any Series of Certificates (including prepayments due to liquidations
of defaulted Contracts) will affect the average life and the maturity of such
Certificates. Prepayments on the Contracts in any Contract Pool may be
influenced by a variety of economic, geographic, social and other factors,
including repossessions, aging, seasonality and interest rates. Other factors
affecting prepayment on such Contracts include changes in housing needs, job
transfers and unemployment. In addition, in the event a partial prepayment is
made on a Contract, or a Contract is prepaid in full, interest on such Contract
to the extent of such prepayment will cease to accrue as of the date of
prepayment. If with respect to any Trust Fund such prepayments and related
interest shortfalls were sufficiently high during a Collection Period, the
Available Distribution Amount (as defined in the applicable Prospectus
Supplement) for the related Distribution Date could be less than the amount of
principal and interest that would be distributable to the related
Certificateholders in the absence of such shortfalls. See "Prepayment and Yield
Considerations" herein and in the related Prospectus Supplement.
 
    DIFFICULTY IN PLEDGING.  To the extent transactions in Certificates can be
effected only through DTC, participating organizations, indirect participants
and certain banks, the ability of a Certificate Owner to pledge any such
Certificate to persons or entities that do not participate in the DTC system, or
otherwise to take actions in respect of such Certificates, may be limited due to
the lack of physical certificates representing any such Certificate. See
"Description of the Certificates--Global Certificates" herein.
 
                                       14
<PAGE>
    POTENTIAL DELAYS IN RECEIPT OF DISTRIBUTIONS.  To the extent any Certificate
is represented by a Global Certificate, Certificate Owners with respect thereto
may experience some delay in their receipt of distributions. Distributions will
be forwarded by the Trustee to DTC and DTC will credit such distributions to the
accounts of its Participants (as defined herein), which will thereafter credit
them to the accounts of Certificate Owners either directly or indirectly through
indirect participants. See "Description of the Certificates--Global
Certificates" herein.
 
    INSOLVENCY, RECEIVERSHIP OR BANKRUPTCY OF CONTRACT SELLERS.  In the event of
an insolvency, conservatorship or receivership of Bank of America, FSB or Bank
of America, as the case may be, or the insolvency or bankruptcy of any affiliate
thereof that has sold Contracts to Bank of America or Bank of America, FSB and
becomes a debtor in a proceeding under the federal bankruptcy code, the sale of
Contracts by Bank of America or Bank of America, FSB or both of them, or the
sale of Contracts by an insolvent affiliate to either of them, as the case may
be, could be recharacterized as a borrowing secured by a pledge of the
Contracts. Such an attempt, even if unsuccessful, could result in delays in or
reductions of distributions on the Certificates. See "Other Considerations"
herein.
 
    INSOLVENCY, CONSERVATORSHIP OR RECEIVERSHIP OF SERVICER.  In the event of a
conservatorship or receivership of Bank of America, FSB (of which BankAmerica
Housing Services is an unincorporated division), the receiver or conservator
could prevent the termination of Bank of America, FSB as Servicer if no event of
default under the applicable Agreement exists other than the receivership or
conservatorship or insolvency of the Servicer. Such restriction could result in
a delay or possibly a reduction in payments on the Certificates to the extent
Bank of America, FSB received (but did not deposit with the trustee) Contract
collections before the date of receivership or conservatorship. See "Other
Considerations" herein.
 
                               THE CONTRACT POOLS
 
    Each Contract contained in a Contract Pool will have been (i) originated by
Bank of America, by Bank of America, FSB, acting through its division,
BankAmerica Housing Services or by SPFSC or purchased by Bank of America, Bank
of America, FSB, acting through its division, BankAmerica Housing Services or by
SPFSC from a manufactured housing dealer on an individual basis in the ordinary
course of its business and/or (ii) purchased by Bank of America, by Bank of
America, FSB, acting through its division, BankAmerica Housing Services, or by
SPFSC, from one or more governmental agencies or instrumentalities and/or from
one or more other lenders or finance companies (including affiliates of the
Sellers) that purchase and hold manufactured housing contracts ("Bulk Sellers"),
all as more particularly specified in the related Prospectus Supplement. Each
Contract will be secured by a new or used Manufactured Home and, in the case of
a Land Home or Land-in-Lieu Contract, by real property upon which the
Manufactured Home is located. Unless otherwise specified in the related
Prospectus Supplement, the Contracts will not be insured by any governmental
agency or instrumentality. However, if so specified in the related Prospectus
Supplement, some or all of the Contracts and collections thereon will, subject
to the conditions described below, be partially insured by the Federal Housing
Administration or partially guaranteed by the Veterans Administration.
 
    On the date of initial issuance of the Certificates of any Series, Bank of
America, Bank of America, FSB or both of them will convey the Contracts
comprising the related Contract Pool to the related Trust Fund. Bank of America,
FSB, through its division, BankAmerica Housing Services, as Servicer, will
obtain and maintain possession of all Contract documents.
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Agreement relating to each Contract Pool will require the related Manufactured
Homes to comply with the requirements of certain federal statutes which
generally would require the Manufactured Homes to have a minimum of 400 square
feet of living space and a minimum width of 102 inches and to be of a kind
customarily used at a fixed location. Such statutes would also require the
Manufactured Homes to be transportable in one or more
 
                                       15
<PAGE>
sections, built on a permanent chassis and designed to be used as dwellings,
with or without permanent foundations, when connected to the required utilities.
The statutes also would require that the security interest in any Manufactured
Home include the plumbing, heating, air conditioning and electrical systems
relating to such Manufactured Home.
 
    Each Agreement will require the Servicer to maintain hazard insurance
policies with respect to each Manufactured Home in the amounts and manner set
forth herein under "Description of the Certificates-- Servicing Compensation and
Payment of Expenses; Certain Matters Regarding the Servicer--A. Hazard Insurance
Policies." Generally, no other insurance will be required with respect to the
Manufactured Homes, the Contracts or any Contract Pool.
 
    Each Contract Pool may contain actuarial or simple interest Contracts (as
further described below) bearing a Contract Rate that is fixed or variable or
increases in specified increments on particular dates (a "Step-Up Rate"). The
rate at which the Contracts in a particular Contract Pool bear interest will be
further described in the applicable Prospectus Supplement. Unless otherwise
specified in the applicable Prospectus Supplement, each Contract will provide
for payments on scheduled monthly due dates (each, a "Due Date"). The day of
each month constituting the Due Date will vary from Contract to Contract. Unless
the Contracts bear interest at a variable rate, the scheduled payment due on
each monthly Due Date (the "Scheduled Payment") will be specified in the
Contract. The Scheduled Payments for fixed-rate Contracts will be constant
assuming no prepayments. Unless otherwise specified in the applicable Prospectus
Supplement, the Scheduled Payments for Contracts bearing interest at a Step-Up
Rate ("Step-Up Rate Contracts") will increase on the dates on which the Contract
Rates are stepped up. In addition, unless otherwise specified in the related
Prospectus Supplement, the Contracts may be prepaid in full or in part at any
time.
 
    Unless otherwise stated in the applicable Prospectus Supplement, Scheduled
Payments whether for actuarial or simple interest Contracts, may be paid prior
to their Due Dates, whether in, or in months prior to, the months of their Due
Dates. Thus, the obligor under a Contract (each, an "Obligor") may, in June, pay
the Scheduled Payments due in June, July and August. In that event, no further
payment will become due on such Contract until the September Due Date. In the
case of a simple interest Contract, the Obligor would have to instruct the
Servicer to apply such payment as a pay-ahead of future Scheduled Payments;
otherwise such payment would be applied as a partial principal prepayment. There
is no limit to the number of Scheduled Payments that may be paid ahead in this
manner. The effect of paid-ahead Scheduled Payments will be different for
actuarial Contracts than for simple interest Contracts, as further described
below.
 
    The Scheduled Payments for each actuarial Contract (whether a fixed rate
Contract or a Step-Up Rate Contract) will fully amortize the principal balance
of the Contract over its term. The portion of each Scheduled Payment allocable
to principal is equal to the total amount thereof less the portion allocable to
interest. The portion of each Scheduled Payment due in a particular month that
is allocable to interest is a precomputed amount equal to one month's interest
on the principal balance of the Contract, which principal balance is determined
by reducing the initial principal balance by the principal portion of all
Scheduled Payments that were due in prior months (whether or not such Scheduled
Payments were timely made) and all prior partial principal prepayments. Thus,
each Scheduled Payment will be applied to interest and to principal in
accordance with a precomputed allocation, whether such Scheduled Payments are
received in advance of or subsequent to their Due Dates. Unless otherwise
specified in the applicable Prospectus Supplement, all payments received in a
Collection Period on an actuarial Contract in excess of the related Obligor's
Scheduled Payment (other than payments not allocated to principal and interest
(such as late payment charges) or payments sufficient to pay in full the
outstanding principal balance of and all accrued and unpaid interest on such
Contract) are applied as a partial prepayment of principal on the Contract,
unless (i) the related Obligor notifies or confirms with the Servicer that such
payments are to be applied to future Scheduled Payments in the order of the Due
Dates of such payments or (ii) the
 
                                       16
<PAGE>
amount of such excess payment is approximately equal (subject to a variance of
plus or minus 10%) to the amount of a future Scheduled Payment.
 
    The Scheduled Payments for each simple interest Contract (whether a fixed
rate Contract or a Step-Up Rate Contract) would, if made exactly on their
respective Due Dates, result in a nearly full amortization of the Contract.
However, each such Scheduled Payment will be applied when received first to
accrued interest on the unpaid principal balance of the Contract (computed on a
daily simple interest basis) and then to principal. Thus, the portions of each
such Scheduled Payment allocable to principal and interest will depend on the
amount of interest accrued to the date payment is received. Unless otherwise
stated in the applicable Prospectus Supplement, no Scheduled Payment on a
Contract will be considered to be delinquent once 90% of the amount thereof is
received. Late payments or payments of less than 100% of any Scheduled Payment
on a simple interest Contract will result in such Contract amortizing more
slowly than originally scheduled and could extend the maturity date of any such
Contract beyond its original scheduled maturity date.
 
    Under certain circumstances, the amount of accrued interest on a simple
interest Contract could exceed the amount of the Scheduled Payment. This could
happen, for example, in the case of delinquency, or in the case of the first
Scheduled Payment due after one or more Scheduled Payments have been paid ahead
as described above (because interest continues to accrue on simple interest
Contracts during the months in which the paid-ahead Scheduled Payments would
have become due). In any such event, the entire amount of the payment will be
allocated to interest, and although some accrued interest will remain unpaid,
the unpaid interest will not be added to the principal balance of the Contract
and will not bear interest. Under other circumstances, no interest will have
accrued between the dates of receipt of Scheduled Payments on simple interest
Contracts. This could be the case if, for example, one or more Scheduled
Payments were paid ahead on a Due Date occurring in a month prior to the months
in which such Scheduled Payments would have become due, as described above. In
that event, the entire amount of such paid-ahead Scheduled Payments generally
will be allocated to principal.
 
    Variable rate Contracts may be either actuarial or simple interest
Contracts. Unless otherwise specified in the related Prospectus Supplement, the
Scheduled Payments on variable rate Contracts will be allocated between
principal and interest as described above for actuarial Contracts and simple
interest Contracts, respectively, based upon the Contract Rate in effect when
such Scheduled Payments are due. Unless otherwise specified in the related
Prospectus Supplement, the amounts of such Scheduled Payments will be adjusted,
on the basis described in such Prospectus Supplement, whenever the related
variable rate is adjusted.
 
    If so specified in the applicable Prospectus Supplement, the related
Contract Pool may contain Contracts which combine certain features of actuarial
and simple interest Contracts as follows: Scheduled Payments will be applied to
principal and interest as if such Contracts were actuarial Contracts, but if any
such Contract is prepaid in full, the amount required to be paid will be
calculated as if the Scheduled Payments received prior to the date of prepayment
were applied to principal and interest in the same manner as they would have
been had such Contract been a simple interest Contract.
 
    If specified in the related Prospectus Supplement, certain Contracts ("Land
Home Contracts" and "Land-in-Lieu Contracts") will also be secured by liens on
the real estate on which the related Manufactured Homes are located. Unless
otherwise specified in the related Prospectus Supplement, all Land Home
Contracts will have financed the purchase of the related Manufactured Home
together with the real estate on which the Manufactured Home is located. In
certain jurisdictions, a lender cannot obtain separate evidence of its lien on
the Manufactured Home securing a Land Home Contract and its lien on the property
on which the Manufactured Home is located. In those jurisdictions, the only
evidence of liens on the Manufactured Homes securing Land Home Contracts will be
the deeds of trust, mortgages or similar security instruments (in each case, a
"Mortgage") on the real estate on which the Manufactured Homes are located. It
is a policy of Bank of America, FSB, acting through its division, BankAmerica
Housing
 
                                       17
<PAGE>
Services, to obtain title insurance policies, where available, with respect to
any such Contract that it originates insuring that the related Manufactured Home
is subject to the lien of the related Mortgage, although title policies may not
have been obtained with respect to Land Home Contracts acquired from Bulk
Sellers and some title insurers will not insure the Manufactured Home unless it
is permanently attached to the land. Where the real estate on which the related
Manufactured Home is located is owned by the related Obligor, the Obligor may
provide a Mortgage on the real estate in lieu of all or part of any required
down payment for any such Contract. Any such Contract is referred to herein as a
"Land-in-Lieu Contract" rather than a "Land Home Contract." Generally, separate
evidences of liens on Manufactured Homes and the real property securing
Land-in-Lieu Contracts are obtained. However, no title insurance is obtained in
respect of such Contracts. See "Certain Legal Aspects of the Contracts--Land
Home and Land-in-Lieu Contracts" herein.
 
    A Contract Pool may include "staged-funding" Contracts which provide
multiple disbursements to an Obligor to finance the purchase of a Manufactured
Home or the acquisition or improvement of the real estate on which the
Manufactured Home will be located. The Obligor pays only the interest on the
disbursed amount of the loan (or an additional origination fee which is
financed, in lieu of interest) until the final disbursement, and, following the
final disbursement, pays both interest and principal. Bank of America, FSB will
represent and warrant in the Agreement that all staged-funding Contracts
included in a Contract Pool will be fully disbursed within 90 days after the
Closing Date, and, if any staged-funding Contract is not fully disbursed within
90 days after the Closing Date, Bank of America, FSB will repurchase that
staged-funding Contract on the next Distribution Date.
 
    The Prospectus Supplement relating to each Series of Certificates will
provide information as of the Cut-off Date for such Series with respect to,
among other things, (i) the number, the aggregate principal balance, and the
range of outstanding principal balances of the Contracts comprising the related
Contract Pool; (ii) the weighted average of the Contract Rates ("Weighted
Average Contract Rate") of the Contracts and the distribution of Contract Rates;
(iii) the weighted average original and remaining terms to maturity of the
Contracts and the distribution of remaining terms to maturity; (iv) the average
outstanding principal balance of the Contracts; (v) the geographical
distribution of the related Manufactured Homes at origination; (vi) the years of
origination of the Contracts; (vii) the distribution of original principal
balances of the Contracts; (viii) the percentage amount of Contracts secured by
new or used Manufactured Homes; (ix) the range of and weighted average
loan-to-value ratios at origination; and (x) the month and year in which the
final scheduled payment date for the Contract with the latest maturity is
scheduled to occur. If a Contract Pool contains Step-Up Rate Contracts, the
related Prospectus Supplement will specify the percentage of the Contract Pool
comprised of such Contracts, the period during which the Contract Rates for such
Contracts will be stepped up, the range of increases in such Contract Rates and
the range of increases in the Scheduled Payments for such Contracts. If a
Contract Pool contains variable rate Contracts, the related Prospectus
Supplement will contain a description of the basis on which such rates are
determined, including any maximum or minimum rates and the frequency with which
any such rate adjusts. The Prospectus Supplement relating to a Series of
Certificates also will contain certain information about Contracts in the
related Trust Fund that are Land Home Contracts, Land-in-Lieu Contracts or
Contracts that are partially guaranteed by the Veterans Administration or
partially insured by the Federal Housing Administration. In addition, to the
extent Bank of America's or Bank of America, FSB's management believes such
information to be material, any Prospectus Supplement may also include
additional information concerning the related Contract Pool that is stored in
the electronic data processing system of the BankAmerica Housing Services
division of Bank of America, FSB.
 
    See "The Sellers" herein for a description of certain origination and
underwriting practices of Bank of America, FSB with respect to manufactured
housing contracts that have been originated by Bank of America, FSB, acting
through its division, BankAmerica Housing Services, or have been purchased by
Bank of America, FSB, acting through its division, BankAmerica Housing Services,
or by SPFSC on an individual basis. To the extent any Contracts in a Contract
Pool were purchased by one or more of the
 
                                       18
<PAGE>
Sellers from one or more Bulk Sellers, the applicable Prospectus Supplement will
contain a description of certain practices observed by such Seller or the
Sellers, as the case may be, in connection with any such purchase.

America, FSB's headquarters are located in Portland, Oregon, and its
administrative offices are located at 555 California Street, San Francisco,
California 94104 (telephone 415-622-2220).
 
BANKAMERICA HOUSING SERVICES, A DIVISION OF BANK OF AMERICA, FSB
 
    Bank of America, FSB has conducted its business of purchasing and
originating manufactured housing installment contracts through its
unincorporated division, BankAmerica Housing Services. BankAmerica Housing
Services is not a separate legal entity from Bank of America, FSB, and all
references in this Prospectus and any Prospectus Supplement to BankAmerica
Housing Services (unless otherwise specified herein) are intended to reflect its
status as a division of, and not a corporate entity separate from, Bank of
America, FSB. In the fourth quarter of 1992, Bank of America, FSB, through its
division, BankAmerica Housing Services, began purchasing and originating
manufactured housing installment contracts through the regional offices in the
United States of its affiliate, Security Pacific Housing Services, Inc.
("SPHSI"). Prior to that time, SPHSI conducted the business of purchasing,
originating, servicing and selling manufactured housing contracts. SPHSI
discontinued the conduct of that business in July 1993, transferring to the
BankAmerica Housing Services division of Bank of America, FSB the regional
office structure, systems and employees relating to that business. The
applicable Prospectus Supplement will contain a description of SPHSI's loan
origination and underwriting practices for any Contract contained in the related
Contract Pool that was originated or purchased by SPHSI on an individual basis
in the ordinary course of its business. The principal office of BankAmerica
Housing Services division of Bank of America, FSB is located at 10089 Willow
Creek Road, San Diego, California 92131-2447 (telephone 619-549-4700).
 
BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION
 
    Bank of America, a wholly-owned subsidiary of BankAmerica Corporation, is a
national banking association. As of June 30, 1997, Bank of America and its
consolidated subsidiaries accounted for approximately 87% of the consolidated
total assets of the BankAmerica Corporation and constituted BankAmerica
Corporation's largest bank subsidiary. As of June 30, 1997, and based on the
Consolidated Report of Condition of Bank of America at such date, Bank of
America and its consolidated subsidiaries had total deposits of $164.7 billion
(including deposits from BankAmerica Corporation and other subsidiaries of
BankAmerica Corporation of $5.2 billion), total assets of $224.3 billion and
capital and surplus of $16.3 billion. Bank of America's headquarters are located
at 555 California Street, San Francisco, California 94104 (telephone
415-622-3530).
 
    Currently, Bank of America originates and purchases manufactured housing
contracts but does not purchase on an individual basis any of the manufactured
housing contracts originated or purchased by Bank of America, FSB. Bank of
America expects that any Contracts it conveys to a Trust Fund will have been
originated or purchased by Bank of America, FSB, acting through its division,
BankAmerica Housing Services, on an individual basis, transferred by Bank of
America, FSB to SPFSC (as further described
 
                                       19
<PAGE>
under "--Loan Originations." below), and purchased by Bank of America from SPFSC
immediately prior to Bank of America's conveyance of such Contracts to a Trust
Fund. If any Contracts that Bank of America conveys to a Trust Fund are not
transferred between Bank of America, FSB, SPFSC and Bank of America in the
foregoing manner, the related Prospectus Supplement will describe the

SECURITY PACIFIC FINANCIAL SERVICES OF CALIFORNIA, INC.
 
    SPFSC is a subsidiary of Bank of America and an affiliate of Bank of
America, FSB. In the second quarter of 1994, SPFSC began purchasing certain
contracts on an individual basis from Bank of America, FSB. SPFSC's headquarters
are located in San Diego, California (telephone 619-578-6150).
 
LOAN ORIGINATIONS
 
    Bank of America, FSB, through its division, BankAmerica Housing Services,
purchases and originates manufactured housing contracts on an individual basis
through 45 regional offices throughout the United States, serving 48 states.
Through the regional offices of BankAmerica Housing Services, Bank of America,
FSB arranges to purchase manufactured housing contracts originated by
manufactured housing dealers located throughout the United States. Generally,
these purchases result from BankAmerica Housing Services division's regional
office personnel contacting dealers located in their regions and explaining Bank
of America, FSB's available financing plans, terms, prevailing rates and credit
and financing policies. If a dealer wishes to make such financing available to
its customers, the dealer must apply for dealer approval. Upon satisfactory
results of BankAmerica Housing Services division's investigation of the dealer's
creditworthiness and general business reputation, Bank of America, FSB and the
dealer will enter into a dealer agreement. Bank of America, FSB, through its
BankAmerica Housing Services division, also originates manufactured housing
contracts directly with customers.
 
    Prior to a regulatory amendment that became effective October 30, 1996, a
federal savings bank, such as Bank of America, FSB, could not maintain in its
portfolio any manufactured housing contract that had a term to maturity of more
than twenty years or any manufactured housing contract with respect to which the
financed amount was greater than 90% of the value of the manufactured home.
Manufactured housing contracts that could not be maintained in the portfolio of
Bank of America, FSB for these reasons were acquired by SPFSC on an individual
basis at or about the time such contracts were originated or purchased by Bank
of America, FSB. The documents of title in respect of a Contract sold by Bank of
America, FSB to SPFSC, then by SPFSC to Bank of America and then by Bank of
America to any Trust Fund will show Bank of America, FSB as the lienholder.
Since January 1997, under the new regulatory amendment, Bank of America, FSB has
originated and held all manufactured housing contracts. See "Risk
Factors--Security Interests in the Manufactured Homes" and "Certain Legal
Aspects of the Contracts--Security Interests in the Manufactured Homes" herein.
 
    In addition to purchasing and originating manufactured housing contracts and
installment loan agreements on an individual basis, Bank of America, FSB, acting
through its division, BankAmerica Housing Services, makes bulk purchases of
manufactured housing contracts. These bulk purchases may be from the portfolios
of other lenders or finance companies (including affiliates of Bank of America,
FSB), the portfolios of governmental agencies or instrumentalities or the
portfolios of other entities that purchase and hold manufactured housing
contracts. Moreover, Bank of America, FSB, acting through its division,
BankAmerica Housing Services, on behalf of other owners (including SPFSC),
services manufactured housing contracts that were not purchased or originated by
Bank of America, FSB. Currently, the servicing of all such contracts is, and
Bank of America, FSB's management currently anticipates, that servicing of all
such contracts will continue to be, performed through the BankAmerica Housing
Services division's manufactured housing regional office system. However, Bank
of America, FSB can provide no assurance that this will continue to be the case.

    The general practices of the BankAmerica Housing Services division of Bank
of America, FSB with regard to the origination of contracts and the purchase of
contracts from manufactured housing dealers are described below under
"--Underwriting Practices." See "--Servicing" below for a description of certain
of Bank of America, FSB's servicing practices.
 
UNDERWRITING PRACTICES
 
    With respect to each retail manufactured housing contract that is purchased
from a dealer, the general practice of Bank of America, FSB, acting through its
division, BankAmerica Housing Services, is to have the dealer submit the
customer's credit application, manufacturer's invoice (if the contract is for a
new home) and certain other information relating to the contract to the
applicable regional office of BankAmerica Housing Services division. Personnel
at the regional office analyze the creditworthiness of the customer and certain
other aspects of the proposed transaction. If the creditworthiness of the
customer and other aspects of the transaction are approved by the regional
office, the customer and the dealer execute a contract on a form provided or
approved in advance by BankAmerica Housing Services division. After the
manufactured home financed under the contract is delivered and set up by the
dealer, and the customer has moved in, Bank of America, FSB purchases the
contract from the dealer.
 
    Because manufactured homes generally depreciate in value, the BankAmerica
Housing Services division's management believes that the creditworthiness of a
potential obligor should be the most important criterion in determining whether
to approve the purchase or origination of a contract. As a result, the
underwriting guidelines of BankAmerica Housing Services division generally
require, and have required, regional office personnel to examine each
applicant's credit history, residence history, employment history and
debt-to-income ratio. There is no minimum requirement for any of these criteria,
although BankAmerica Housing Services division has developed certain guidelines
for employment history and debt-to-income ratios. In the case of employment
history, BankAmerica Housing Services division generally requires its regional
office personnel to consider whether the applicant has worked continuously for
the same employer for at least 24 months and, if not, whether the applicant has
worked in the same occupational field for at least 24 months. The recommended
debt-to-income ratio for a particular credit application depends on the credit
score recommendation (described below) generated for that application. In
general, the maximum debt-to-income ratio for each application that is either
recommended for approval or approved by the credit scoring system ranges from 70
percent to 53 percent, based on BankAmerica Housing Services division's estimate
of the applicant's after-tax income. Although BankAmerica Housing Services
division has guidelines for some of these criteria, the division's management
does not believe that an applicant's inability to satisfy some of these
guidelines warrants denial of credit in all cases. For example, if an applicant
fails to meet a guideline by a certain margin for one of the criteria mentioned
above, the applicant generally must exceed the threshold for one or more other
criteria by a compensating margin for such applicant's credit application to be
approved. In addition, in special cases, credit applications are approved even
if certain of the criteria are not met. For these reasons, management of
BankAmerica Housing Services division believes that the ultimate decision
whether to approve or reject a credit application should be made by regional
office personnel. To assist personnel in evaluating credit applications, the
division began using a Fair-Isaacs credit scoring system in January 1995. The
Fair-Isaacs credit scoring system generates a recommendation to approve or deny
a credit application based on certain criteria established by BankAmerica
Housing Services division. The underwriting guidelines of BankAmerica Housing
Services division allow the recommendation generated by the Fair-Isaacs credit
scoring system to be used by regional personnel as a guide in determining
whether to extend credit to an applicant, but do not require regional personnel
to make credit decisions based solely on the system's recommendations.
BankAmerica Housing Services division does not disclose the criteria used by
this credit scoring system either to regional personnel or to the dealers
assisting in the preparation of credit applications. The criteria is
periodically reviewed by management at the headquarters of the BankAmerica
Housing Services division, and modified as necessary. In July, 1997, the
BankAmerica Housing Services division implemented a new Fair-Isaacs credit
scoring system.
 
                                       21
<PAGE>
    It is the policy of the BankAmerica Housing Services division that one
authorized person provide written approval of credit applications for amounts up
to or equal to certain limits and that two authorized persons provide written
approval of credit applications for amounts over those limits. The credit limits
established by the division vary with each regional office. In addition, each
person authorized to make these credit decisions has to be either a regional
manager or another regional office employee to whom the authority to approve
credit applications has been delegated. Any such delegated authority may be
limited in that the person to whom such authority is delegated may not be
authorized to approve credit applications for contracts with initial principal
amounts above certain specified levels. The qualifications of all regional
office personnel authorized to approve or reject credit applications are
reviewed and approved by the BankAmerica Housing Services division's senior
management. Generally, both the dealer service manager and the credit manager in
each regional office (in addition to the regional manager) have authority to
approve credit applications. However, each regional office may at various times
have additional, or in some cases fewer, personnel authorized to approve or
reject credit applications. The BankAmerica Housing Services division has no set
qualifications for regional managers or for other employees to whom authority to
approve credit applications may be delegated; rather, such authority is given
commensurate with such manager's or employee's experience.
 
    It is and has been the policy of the BankAmerica Housing Services division
that each credit application be approved or rejected within one to seven days
after receipt. Thus, there is less time for credit investigation than is the
case, for example, with loans for site-built homes. Although the BankAmerica
Housing Services division's management believes that the seven-day period for
approval or rejection of each credit application is consistent with industry
practice, no assurance can be given that any credit application that was
approved in one to seven days would have been approved if a longer period had
been provided for credit investigation.
 
    The credit review and approval practices of each regional office are subject
to internal reviews and audits (which are performed in certain instances by an
affiliate of Bank of America, FSB) that, through sampling, examine the nature of
the verification of credit histories, residence histories, employment histories
and debt-to-income ratios of the applicants and evaluate the credit risks
associated with the contracts purchased through such regional offices by rating
the obligors on such contracts according to their credit histories, employment
histories and debt-to-income ratios. Selection of underwriting files for review
is generally made by the personnel performing the examination, without prior
knowledge on the part of regional office personnel of the files to be selected
for review. However, the BankAmerica Housing Services division has no
requirement that any specific random selection procedures be followed and no
assurance can be given that the files reviewed in any examination process are
representative of the contract originations in the related regional office. In
addition, no statistical analysis is performed on the results of any such
examination of underwriting files.
 
    Conventional manufactured housing contracts (that is, contracts that are not
insured or guaranteed by a governmental agency or instrumentality) currently
comprise 100% (by initial principal balance) of the manufactured housing
contracts purchased or originated by Bank of America, FSB through its division,
BankAmerica Housing Services. However, Bank of America, FSB can provide no
assurance that it will not seek to originate or purchase manufactured housing
contracts, whether on an individual basis from authorized dealers or in bulk
from Bulk Sellers, that are partially insured or guaranteed by one or more
governmental agencies or instrumentalities.
 
    Before May 1994, in the case of conventional manufactured housing contracts
secured by new manufactured homes, it was the policy of BankAmerica Housing
Services division to finance no more than the lower of (i) 125% of the
manufacturer's invoice price plus taxes, insurance, freight charges, certain
dealer installed equipment and certain set-up costs and (ii) 90% of the buyer's
total cost of any new manufactured home. A buyer's cost includes certain fees,
sales tax and certain insurance premiums (including up to five years of premiums
on required hazard insurance). Before May 1994, in the case of conventional
manufactured housing contracts secured by used manufactured homes, the maximum
amount
 
                                       22
<PAGE>
financed by BankAmerica Housing Services was the lower of (i) 90% of retail
value, as specified in the National Automobile Dealers Association ("NADA")
Mobile/Manufactured Housing Appraisal Guide or the "Kelley Blue Book," plus
taxes, insurance, and certain set-up costs, and (ii) an amount determined by
BankAmerica Housing Services using a formula based on the square feet, age and
type of manufactured home, plus sales tax, license fee and insurance.
 
    Since May 1994, it has been the policy of BankAmerica Housing Services
division to finance, with respect to new and used manufactured homes, no more
than 95% of the total buyer's cost of any manufactured home (including taxes and
insurance premiums) plus 100% of the costs attributable to prepaid finance
charges and closing costs that are financed. In the case of new manufactured
homes, the maximum amount financed also cannot exceed 130% of the manufacturer's
invoice price plus taxes, insurance, freight charges, certain dealer installed
equipment and certain set-up costs. For used manufactured homes, the amount
financed cannot exceed 95% of the retail value, as specified in the NADA
Mobile/Manufactured Housing Appraisal Guide or the "Kelley Blue Book" plus
taxes, insurance and certain set-up costs. For Land Home and Land-in-Lieu
Contracts, it is the policy of BankAmerica Housing Services division to finance
no more than (i) 95% of the value of the real property as determined by
appraisal or tax assessment, plus the total buyer's cost of the manufactured
home (including taxes and insurance premiums), plus the cost of improvements to
the land and 100% of the costs attributable to prepaid finance charges and
closing costs that are financed or (ii) in the case of a manufactured home that
is already located on the land, 95% of the final appraised value of the land and
manufactured home together and 100% of the costs attributable to prepaid finance
charges and closing costs that are financed. BankAmerica Housing Services
division also has had a policy from May 1994 to July 1995 not to finance
manufactured housing contracts for terms exceeding 25 years. In July 1995, that
policy was modified to permit financing of manufactured housing contracts for
terms up to 30 years. Prior to January 1, 1997, manufactured housing Contracts
exceeding 90% loan-to-value or 20 years duration were acquired by SPFSC on an
individual basis at or about the time such Contracts were originated or
purchased by BankAmerica Housing Services. Beginning in January, 1997, all
manufactured housing contracts are originated and held by Bank of America, FSB.
An OTS amendment that was effective October 30, 1996 removed the loan-to-value
and maximum term limitations from the regulations applicable to Federal Savings
Banks.
 
    BankAmerica Housing Services division requires a down payment in the form of
cash and/or the trade-in value of a previously owned manufactured home and/or,
in the case of Land in Lieu Contracts, an estimated value of equity in real
property pledged as an additional collateral. For previously owned homes, the
trade-in allowance accepted by the dealer must be consistent with the value of
such home determined by BankAmerica Housing Services division in light of
current market conditions. The value of real property pledged as additional
collateral is estimated by regional personnel or appraisers who are familiar
with the area in which the property is located.
 
    Underwriting policies for the origination or purchase on an individual basis
of manufactured housing contracts are established by BankAmerica Housing
Services division's management at its headquarters in San Diego and are
applicable to all regional offices in BankAmerica Housing Services' manufactured
housing regional office system.

SERVICING
 
    Bank of America, FSB, through the manufactured housing regional office
system of its division, BankAmerica Housing Services, services all of the
manufactured housing contracts that it purchases or originates, whether on an
individual basis or in bulk. Generally, whenever any contracts are sold, Bank of
America, FSB will retain servicing responsibilities with respect to such
contracts. In addition, Bank of America, FSB has made arrangements, and is
actively seeking further arrangements, pursuant to which it services, or would
service, manufactured housing contracts owned by other entities. Such contracts
would not be purchased by Bank of America, FSB. Generally, such servicing
responsibilities are, and would be, carried out through the manufactured housing
regional office system of its division, BankAmerica Housing Services. Bank of
America, FSB, through its division, BankAmerica Housing Services, also services
contracts purchased on an individual basis or in bulk by SPHSI or SPFSC, as well
as those previously serviced (but not owned) by SPHSI. Servicing
responsibilities include collecting principal and interest payments, taxes,
insurance premiums and other payments from obligors and, when such contracts are
not owned by Bank of America, FSB, remitting principal and interest payments to
the owners thereof, to the extent such owners are entitled thereto. Collection
procedures include repossession and resale of manufactured homes securing
defaulted contracts (and foreclosure if land is involved) and, if deemed
advisable by Bank of America, FSB, entering into workout arrangements with
obligors under certain defaulted contracts. Although decisions as to whether to
repossess any manufactured home are made on an individual basis, Bank of
America, FSB's general policy is to institute repossession procedures promptly
after regional office personnel determine that it is unlikely that a defaulted
contract will be brought current, and thereafter to diligently pursue the resale
of such manufactured homes. See "--Delinquency

  BANK OF AMERICA, FSB'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF DELINQUENCY,
                     REPOSSESSION AND LOAN LOSS EXPERIENCE
 
    The delinquency, repossession and loan loss experience exhibited by the
foregoing tables for the periods referenced therein are for illustrative
purposes only and there is no assurance that the delinquency, repossession or
loan loss experience of any Contracts sold to a Trust Fund will be similar to
that set forth above. Management has not observed any material economic
development in the general business environment of the country or in local areas
where Bank of America, FSB's manufactured housing contracts are originated which
have unfavorably affected portfolio performance in relation to delinquencies,
repossessions and loan losses during this period.
 
    No assurance can be given that local or national economic conditions may not
in the future adversely affect portfolio performance in these respects.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
PREPAYMENT CONSIDERATIONS
 
    Unless otherwise specified in the related Prospectus Supplement, the
Contracts in any Contract Pool may be prepaid in full or in part at any time.
The prepayment experience of the Contracts (including prepayments due to
liquidations of defaulted Contracts) will affect the average life and the
maturity of the related Certificates. Bank of America, FSB does not maintain
statistics with respect to the rate of prepayment of manufactured housing
contracts in its servicing portfolio, except for certain pools of manufactured
housing contracts sold by SPHSI, business predecessor of the BankAmerica Housing
Services division of Bank of America, FSB, and certain pools of manufactured
housing contracts sold by Bank of America, FSB, Bank of America or SPFSC for
which at least eighteen months of prepayment information is available. As to
such pools, the Prospectus Supplement for any Series of Certificates will
contain information concerning the historical rates of prepayment on
manufactured housing contracts in such pools through a date as to which such
information is available as of the date of such Prospectus Supplement. For
example, a Contract Pool might include Contracts with Contract Rates that are
generally higher or lower, in absolute terms or in comparison to prevailing
rates, than the contract rates of the contracts from which are derived certain
historical statistical data set forth in the Prospectus or Prospectus
Supplement. As a result, the prepayment performance of the Contracts contained
in that Contract Pool might be higher or lower than the prepayment performance
of the contracts reflected in the historical data. In addition, Housing
Services' management is aware of limited publicly available information relating
to historical rates of prepayment on manufactured housing contracts. However,
Bank of America, FSB's management believes that neither the prepayment
experience of other pools of manufactured housing contracts nor the historical
rates of prepayment for any other manufactured housing contracts will
necessarily be indicative of the rate of prepayment that may be expected to be
exhibited by the Contracts in any other Contract Pool. Nevertheless, Bank of
America, FSB's management anticipates that a number of Contracts will be prepaid
in full in each year during which any related Certificates are outstanding. The
amount of prepayments on such Contracts (including prepayments due to
liquidations of defaulted Contracts) during any particular year may be
influenced by a variety of economic, geographic, social and other factors,
including repossessions, aging, seasonality, interest rates and the rate at
which manufactured homeowners sell their manufactured homes. Other factors
affecting prepayments on such Contracts include changes in Obligors' housing
needs, job transfers, unemployment and Obligors' net equity in manufactured
homes. Because of the depreciating nature of manufactured housing, which limits
the possibilities for refinancing, and because the terms of manufactured housing
contracts are generally shorter than the terms for mortgage loans secured by
site-built homes (and changes in interest rates have a correspondingly smaller
effect on the monthly payments on manufactured housing contracts as opposed to
mortgage loans secured by site-built homes), changes in interest rates may play
a smaller role in prepayment behavior of manufactured housing contracts than
they do in the prepayment behavior of loans secured by mortgages on site-built
homes. Conversely, local economic conditions and certain of the other
 
                                       28
<PAGE>
factors mentioned above are likely to play a larger role in the prepayment
behavior of manufactured housing contracts than they do in the prepayment
behavior of loans secured by mortgages on site-built homes.
 
    Repurchases of Contracts on account of certain breaches of representations
and warranties as described in the applicable Prospectus Supplement also will
have the effect of prepaying such Contracts and therefore will affect the
average life of and yield on the Certificates. See "Description of the
Certificates--Conveyance of Contracts." In addition, most of the Contracts
contain provisions that prohibit the related owner from selling the Manufactured
Home without the prior consent of the holder of the related Contract. Such
provisions are similar to "due-on-sale" clauses and may not be enforceable in
certain states. See "Certain Legal Aspects of the Contracts--Transfers of
Manufactured Homes; Enforceability of Restrictions on Transfer" herein. The
Servicer's policy is to permit most sales of Manufactured Homes where the
proposed buyer meets the Servicer's then current underwriting standards and
enters into an assumption agreement.
 
    To the extent provided in the related Prospectus Supplement, the Servicer
under each Agreement will have the option to purchase all of the Contracts in
the related Contract Pool, at the price and under the conditions specified in
such Prospectus Supplement, when the aggregate Pool Principal Balance (as
defined in the related Prospectus Supplement) of the Contract Pool has been
reduced to 10% of its initial Pool Principal Balance. The exercise of any such
option will affect the average life of and yield on the related Certificates. To
the extent provided in the related Prospectus Supplement, the Trustee for the
related Trust Fund shall solicit bids for the purchase of the Contracts
remaining in the Trust Fund at a Termination Auction (as defined herein) within
ninety days following the Distribution Date as of which the Pool Principal
Balance for a Contract Pool is less than 10% of such Contract Pool's Cut-off
Date Pool Principal Balance. The sale and consequent termination of the related
Trust Fund pursuant to a Termination Auction will affect the average life and
yield on the related Certificates.
 
    The average life and maturity of the Certificates of any Class will also be
affected by the amount and timing of any Special Principal Distributions to the
holders of such Certificates. In addition, if any Certificate of a Class is
subject to mandatory repurchase, the occurrence of the Repurchase Date (as
hereinafter defined) for such Certificate will have the same effect as the
maturation of such Certificate (with the repurchase price being equivalent to
the amount due at maturity). See "Description of the Certificates--Distributions
on Certificates" and "Description of the Certificates--Optional and Mandatory
Repurchase of Certificates; Termination Auction" herein. The Prospectus
Supplement relating to any Class that is entitled to Special Principal
Distributions or is subject to mandatory repurchase will contain a description
of the conditions under which such distributions or repurchases will take place
and a description of some of the factors that might affect the rate of Special
Principal Distributions or the timing of any Repurchase Dates.
 
    Information regarding the "Prepayment Model" (to be defined in the related
Prospectus Supplement) or any other rate of assumed prepayment, as applicable,
will be set forth in the Prospectus Supplement applicable to the relevant Class
or Classes of Certificates offered hereby.
 
YIELD CONSIDERATIONS
 
    To the extent that any credit enhancement or any advancing obligation of the
Servicer described in the related Prospectus Supplement is insufficient to
protect the holders of any Class of Certificates from losses or delinquencies on
the related Contract Pool, the yield to such holders from their investment in
such Certificates will be adversely affected should such losses or delinquencies
occur. In the absence of losses or delinquencies which are not covered by credit
enhancement or advances, respectively, on a Distribution Date, the effective
yield on the Certificates will depend upon, among other things, the price at
which the Certificates are purchased, the rate at which the Contracts for the
related Trust Fund liquidate or are prepaid and the amount and timing of any
Special Principal Distributions. If a purchaser of Certificates
 
                                       29
<PAGE>
purchases them at a discount (premium) and calculates its anticipated yield to
maturity based on an assumed rate of distributions of principal on such
Certificates that is faster (slower) than the rate actually realized, such
purchaser's actual yield to maturity will be lower than the yield so calculated
by such purchaser. Losses which are covered by credit enhancement, but on later
than anticipated Distribution Dates, will have the same effect on anticipated
yield as prepayments that are made later than anticipated, as just described,
depending on whether the Certificates were purchased at a discount or premium.
 
    The yield to holders of any Class of Certificates may be below that
otherwise produced by the applicable Pass-Through Rate because, while, in the
absence of losses or delinquencies, one month's interest on the related
Contracts will be collected during each Collection Period, the portion of such
interest to which the holders of such Certificates are entitled will not be
distributed until the first Distribution Date after such Collection Period.
 
    If a Certificate is subject to mandatory repurchase, the yield to the
Repurchase Date will be affected by, among other things, the applicable
repurchase price, the ability of any Liquidity Facility Provider (as hereinafter
defined) to distribute the repurchase price and the date, if any, on which the
Repurchase Date occurs. If, in connection with a mandatory repurchase, the
repurchase price for a Certificate is equal to its Percentage Interest (as
hereinafter defined) of the then current Certificate Balance, and the
Certificate is purchased at a discount, and the purchaser calculates its
anticipated yield to the Repurchase Date based on an assumed Repurchase Date
that is earlier than the actual Repurchase Date, then such purchaser's actual
yield to maturity will be lower than it would have been if a repurchase occurred
on the assumed date.
 
    The payment features of the Contracts comprising any Contract Pool (as
described above under "The Contract Pools") may, under certain extraordinary
circumstances, cause the amounts collected thereon during particular Collection
Periods to be insufficient to fund all distributions of principal and interest
to the holders of some or all of the Certificates of the related Series, even in
the absence of losses or delinquencies. Such circumstances could occur if a
sufficiently large number of partial or full prepayments, as a percentage of the
then outstanding Pool Principal Balance of the related Contract Pool, are
received on Contracts in a particular Collection Period, if such prepayments are
made in advance of such Contracts' respective Due Dates during such Collection
Period. In such case, a non-default collection shortfall could occur because
interest that actually accrues on such Contracts is less than interest that
would have accrued if the payments were paid on the Contracts' respective Due
Dates. A non-default collection shortfall could adversely affect the yield to
holders of any Class of Certificates to the extent such shortfalls are not
covered by credit enhancement or advances.
 
                        DESCRIPTION OF THE CERTIFICATES
 
    Each Series of Certificates will be issued pursuant to a separate Agreement.
The following summaries describe certain provisions expected to be common to
each Agreement and the related Certificates, but do not purport to be complete
and are subject to, and are qualified in their entirety by reference to, the
provisions of the related Agreement and the description set forth in the related
Prospectus Supplement. Section references contained herein refer to sections of
the form of Agreement filed as an exhibit to the Registration Statement. The
Prospectus Supplement for each Series will describe the specific material
provisions of the Agreement relating to such Series. Capitalized terms used and
not otherwise defined herein shall have the meanings assigned to them in the
form of Agreement filed as an exhibit to the Registration Statement.
 
GENERAL
 
    The Certificates may be issued in one or more Classes. If the Certificates
of a Series are issued in more than one Class, the Certificates of all or less
than all of such Classes may be sold pursuant to this Prospectus, and there may
be separate Prospectus Supplements relating to one or more of such Classes so
 
                                       30
<PAGE>
sold. Any reference herein to the Prospectus Supplement relating to a Series
comprised of more than one Class should be understood as a reference to each of
the Prospectus Supplements relating to the Classes sold hereunder. Any reference
herein to the Certificates of a Class should be understood to refer to the
Certificates of a Class within a Series, the Certificates of a subclass within a
Series or all of the Certificates of a single-Class Series, as the context may
require.
 
    The Certificates will be issued in the denominations specified in the
related Prospectus Supplement. (Section 6.02.) The "Percentage Interest" of a
Certificate is the percentage obtained from dividing the original denomination
of such Certificate by the initial principal balance of all of the Certificates
of such Class. Interest-only Certificates will have no Percentage Interest.
Certificates, if issued in registered form ("Definitive Certificates") to
Certificate Owners or nominees thereof, will be transferable and exchangeable at
the corporate trust office of the Trustee or, if it so elects, at the office of
an agent in New York, New York. (Sections 6.02 and 9.11.) No service charge will
be made for any registration of exchange or transfer, but the Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge. (Section 6.02.)
 
    The Certificates of each Series will evidence an interest, as specified in
the related Prospectus Supplement, in a Trust Fund. Each Trust Fund will include
(i) a Contract Pool, including certain rights to receive payments on the
Contracts comprising such Contract Pool on and after the Cut-off Date, (ii) the
amounts held from time to time in the "Certificate Account" (as described in the
applicable Prospectus Supplement under "--Payment on Contracts; Certificate
Account") maintained by the Trustee pursuant to the Agreement, (iii) any
property which initially secured a Contract and which is acquired in the process
of realizing thereon, (iv) the obligations of Bank of America, Bank of America,
FSB or both of them, as applicable, under certain conditions, to repurchase
Contracts sold by it with respect to which certain representations and
warranties have been breached and not cured, (v) certain contractual servicing
obligations of the Servicer, (vi) the proceeds of all insurance policies
described herein and (vii) if applicable, one or more forms of credit support.
 
    Bank of America, Bank of America, FSB or both of them, as applicable, will
convey the Contracts to the Trustee. See "The Contract Pools" herein and
"--Conveyance of Contracts" below. Bank of America, FSB, acting through its
division, BankAmerica Housing Services, as Servicer, will service the Contracts
pursuant to the Agreement. The Contract documents will be held for the benefit
of the Trustee by the Servicer.
 
CONVEYANCE OF CONTRACTS
 
    On the date of initial issuance of the Certificates of a Series, Bank of
America, FSB, Bank of America, or both of them will sell to the Trustee, without
recourse, all right, title and interest of Bank of America, FSB or Bank of
America, as the case may be, in and to the Contracts sold by it, and all rights
under the standard hazard insurance policies on the related Manufactured Homes.
The conveyance of the Contracts to the Trustee will include a conveyance of all
rights to receive Scheduled Payments thereon that were due on or after the
Cut-off Date, even if received prior to the Cut-off Date, as well as all rights
to any payments received on or after the Cut-off Date other than late receipts
of Scheduled Payments that were due prior to the Cut-off Date. The Contracts
will be described on a schedule attached to the Agreement (the "Contract
Schedule"). The Contract Schedule will include the principal balance of each
Contract as of the Cut-off Date, the amount of each Scheduled Payment due on
each Contract as of the Cut-off Date, the Contract Rate on each Contract
(determined as of the Cut-off Date) and the maturity date of each Contract.
Prior to the conveyance of the Contracts to the Trustee, BankAmerica Housing
Services division's operations department will be required to complete a review
of all of the originals of the Contracts, the certificates of title to, or other
evidence of a perfected security interest in, the Manufactured Homes, any
related Mortgages, if any, and any assignments or modifications of the foregoing
(collectively, the "Contract Files") confirming the accuracy of the Contract
Schedule delivered to the Trustee. Any Contract discovered not to agree with
such schedule in a manner that is materially adverse to the interests of the
 
                                       31
<PAGE>
Certificateholders will be repurchased by Bank of America or Bank of America,
FSB, as applicable, or replaced with another Contract, except that if the
discrepancy relates to the principal balance of a Contract (determined as
described above), Bank of America or Bank of America, FSB, as applicable, may,
under certain conditions, deposit cash in the Certificate Account in an amount
sufficient to offset such discrepancy. The Trustee will not review the Contract
Files. (Section 2.01.)
 
    The Servicer will hold, as custodian and agent on behalf of the Trustee, the
original Contracts and copies of documents and instruments relating to each
Contract and the security interest in the Manufactured Home, and real property,
if any, relating to each Contract. In order to give notice of the Trustee's
right, title and interest in and to the Contracts, a UCC-1 financing statement
identifying the Trustee as the secured party and identifying all the Contracts
as collateral will be filed in the appropriate office in the appropriate states.
The Contracts will be stamped or otherwise marked to reflect their assignment to
the Trustee. To the extent that the Contracts do not constitute "chattel paper"
within the meaning of the UCC as in effect in the applicable jurisdictions or to
the extent that the Contracts do constitute chattel paper and a subsequent
purchaser is able to take physical possession of the Contracts without notice of
such assignment, the Trustee's interest in the Contracts could be defeated. See
"Certain Legal Aspects of the Contracts--Security Interests in the Manufactured
Homes" and "Land Home and Land-in-Lieu Contracts" herein.
 
    Bank of America, Bank of America, FSB or both of them, as applicable, will
make certain representations and warranties to the Trustee with respect to each
Contract sold by it. The applicable Prospectus Supplement will describe the
representations and warranties made by Bank of America, Bank of America, FSB or
both of them in connection with the Contracts conveyed to the related Trust
Fund, the terms pursuant to which Bank of America or Bank of America, FSB, as
the case may be, will be obligated to repurchase, at the price specified
therein, any Contract sold by it if any such representation and warranty has
been breached (unless such breach has been cured or otherwise is not required to
be cured), and the terms pursuant to which Bank of America or Bank of America,
FSB may remedy any such breach. (Section 3.05.)
 
PAYMENTS ON CONTRACTS
 
    The applicable Prospectus Supplement will specify the arrangements pursuant
to which Contract collections are held pending distribution to
Certificateholders. (Section 4.05.) Certain Contract collections will be applied
to pay the Servicer's servicing compensation and to reimburse it for certain
expenses, as set forth in each Prospectus Supplement and as set forth herein
under "--Servicing Compensation and Payment of Expenses; Certain Matters
Regarding the Servicer" below.
 
    If so provided in the applicable Prospectus Supplement, for as long as Bank
of America, FSB remains the Servicer under the Pooling and Servicing Agreement
and Bank of America, FSB maintains the minimum short-term rating from a
nationally recognized statistical rating organization specified in the
applicable Prospectus Supplement, the Servicer may use payments in respect of
principal and interest received on the Contracts for its own benefit until the
related Distribution Date without an obligation to pay interest or any other
investment return, it being understood that any benefit to Bank of America, FSB
from this arrangement shall be additional servicing compensation. While such
rating is maintained, on or prior to each Distribution Date, the Servicer will
deposit in the Certificate Account amounts which are to be included in the funds
available for the related Distribution Date. If so provided in the applicable
Prospectus Supplement, amounts deposited in the Certificate Account may be
invested in Permitted Investments (as described in the Pooling and Servicing
Agreement) maturing no later than the related Distribution Date.
 
    If the Servicer is entitled to delay payments to the Certificate Account as
described above, but its short-term rating does not satisfy the rating
requirements specified above, the Servicer may, if permitted in the applicable
Prospectus Supplement, continue to hold collections prior to distribution as
described above
 
                                       32
<PAGE>
so long as the Servicer causes to be maintained an irrevocable letter of credit
or surety bond or other credit enhancement instrument in form and substance
satisfactory to the rating agency, issued by a depository institution or
insurance company having the minimum rating from a nationally recognized
statistical rating organization specified in the applicable Prospectus
Supplement and providing that the Trustee may draw thereon in the event that
Bank of America, FSB, as Servicer, fails to make any deposit or payment required
under the Pooling and Servicing Agreement.
 
DISTRIBUTIONS ON CERTIFICATES
 
    The Certificates of any Class will entitle the holders thereof to
distributions, on the Distribution Dates specified in the related Prospectus
Supplement, from amounts collected on the underlying Contracts. The Certificates
of a Class may entitle the holders thereof to (a) distributions of both
principal and interest, (b) distributions of principal only, or (c)
distributions of interest only. Such distributions will be made in accordance
with a formula described in the related Prospectus Supplement, and, unless
otherwise specified in such Prospectus Supplement, such distributions will be
applied first to interest, if any, and second to principal, if any. To the
extent specified in the related Prospectus Supplement, the rights of the holders
of the Certificates of one or more Classes of a multiple Class Series to receive
distributions of principal or of interest or of both from amounts collected on
the Contracts may be subordinate to such rights of the holders of Certificates
of one or more other Classes. See "Credit and Liquidity Enhancement" herein.
 
    A.  DISTRIBUTIONS OF PRINCIPAL.  If the Certificates of a Class entitle the
holders thereof to distributions of principal, the related Prospectus Supplement
will specify an initial aggregate Certificate Balance for the Certificates of
such Class and a method of computing the amount of principal, if any, to be
distributed to the holders of such Certificates on each Distribution Date.
Unless otherwise specified in the related Prospectus Supplement, principal
distributions for the Certificates of a Class will be computed on the basis of a
formula which, on each Distribution Date, allocates all or a portion of the
Total Regular Principal Amount relating to such Distribution Date to the
Certificates of such Class. The "Total Regular Principal Amount" is the total
amount by which the aggregate outstanding principal balance of the Contracts in
the related Contract Pool is reduced during one or more collection periods prior
to such Distribution Date designated in such Prospectus Supplement (each, a
"Collection Period"). Such reduction may occur as a result of actuarially
predetermined scheduled principal reductions, receipt of principal prepayments,
liquidation of Contracts, repurchases of Contracts under certain conditions,
losses on Contracts, the failure of a third party credit support provider, if
any, to make a required payment, or a combination of any of the foregoing
events. See "The Contract Pools" and "--Servicing Compensation and Payment of
Expenses; Certain Matters Regarding the Servicer" herein. Distributions with
respect to all or a portion of the Total Regular Principal Amount are sometimes
referred to herein as distributions of "Regular Principal." The Total Regular
Principal Amount with respect to any Contract Pool and any Distribution Date may
be estimated in a manner specified in the related Prospectus Supplement.
 
    If, due to liquidation losses or other circumstances adversely affecting the
collections on the underlying Contract Pool, the Contract collections available
on any Distribution Date to make distributions of Regular Principal to the
holders of the Certificates of a Class are less than the portion of the Total
Regular Principal Amount allocable to such Class, the deficiency may be made up
from (i) the amount ("Excess Interest"), if any, by which the interest collected
on nondefaulted Contracts during the same Collection Period exceeds the interest
distribution due to the holders of the Certificates for the related Series and
the Monthly Servicing Fee (as defined hereinafter and in the related Prospectus
Supplement), or (ii) funds available from one or more forms of credit support
referred to below, but only to the extent, if any, specified in the applicable
Prospectus Supplement. See "Credit and Liquidity Enhancement" herein. If
specified in the applicable Prospectus Supplement, the Certificate Balance of
the Certificates of a Class will be reduced on each Distribution Date by the
full amount of the portion of the Total Regular Principal Amount allocable to
such Class even if, due to deficient Contract collections, a full distribution
thereof is not made.
 
                                       33
<PAGE>
    The applicable distribution formula for each Class of a multiple-Class
Series may allocate the Total Regular Principal Amount among the various Classes
on a pro rata, sequential or other basis, as specified in the related Prospectus
Supplement. If specified in the related Prospectus Supplement, any such formula
may entitle the holders of Certificates of a particular Class to receive on
certain Distribution Dates, distributions of Regular Principal from particular
sources of funds (e.g., one or more of the forms of credit support referred to
below) upon the occurrence of certain losses or delinquencies, even if the
holders of the Certificates of such Class would not have been entitled to
receive principal distributions on such Distribution Dates from amounts
collected on the underlying Contracts in the absence of such losses or
delinquencies.
 
    If specified in the applicable Prospectus Supplement, the Certificates of a
Class may entitle the holders thereof to special principal distributions on
particular Distribution Dates that are unrelated to the Total Regular Principal
Amount for any such Distribution Date ("Special Principal Distributions").
Special Principal Distributions may be made, under the circumstances set forth
in the applicable Prospectus Supplement, from interest collected on the
underlying Contract Pool, from funds available from one or more forms of credit
support or from any other source specified in such Prospectus Supplement. The
Certificates of a Class having an initial Certificate Balance may entitle the
holders thereof to distributions of Regular Principal only, to distributions of
Regular Principal and to Special Principal Distributions or to Special Principal
Distributions only. However, unless otherwise stated in the related Prospectus
Supplement, the Certificates of a Class will not entitle the holders thereof to
aggregate principal distributions in excess of the initial Certificate Balance
for such Class.
 
    B.  DISTRIBUTIONS OF INTEREST.  The distribution formula for a Class of
Certificates having an initial Certificate Balance may, but need not, also
specify a method of computing the interest, if any, to be distributed on
specified Distribution Dates (which may include all or less than all of the
Distribution Dates) to the holders of the Certificates of such Class. Such
interest may be equal, subject to such adjustments as may be described in the
related Prospectus Supplement, to a specified number of days' interest on the
applicable Certificate Balance (before giving effect to any reduction thereof on
such Distribution Date), calculated at a rate (the "Pass-Through Rate")
specified in the related Prospectus Supplement. The Pass-Through Rate may be
fixed or variable, and, if specified in the related Prospectus Supplement, may
shift from a variable rate to a fixed rate under the conditions specified in
such Prospectus Supplement. Variable Pass-Through Rates may vary from time to
time based upon changes in an index or other measure of certain market rates,
all as more fully described in the related Prospectus Supplement. In that case,
the time period between Pass-Through Rate adjustments (each, a "Rate Period")
and the specific basis on which the Pass-Through Rate for each Rate Period will
be determined (including the particular market rates and measures thereof
relevant for determining the Pass-Through Rate for each Rate Period) may remain
constant or may change from time to time at the election of the Servicer or
otherwise, all as specified in the related Prospectus Supplement. Variable
Pass-Through Rates may also vary from time to time, in the manner specified in
the related Prospectus Supplement, based upon changes in the weighted average of
the Contract Rates of the Contracts in the related Contract Pool or on any other
basis. To the extent set forth in the related Prospectus Supplement, variable
Pass-Through Rates may also have floor rates and/or ceiling rates which may be
fixed or subject to adjustment as set forth in such Prospectus Supplement. In
addition, a variable Pass-Through Rate may be converted to a fixed Pass-Through
Rate at the election of the Sellers or upon the occurrence of certain
conditions. In that event, the related Prospectus Supplement will set forth the
conditions under which the variable Pass-Through Rate may be converted to a
fixed Pass-Through Rate.
 
    Rather than entitling the holders thereof to receive distributions of
interest based upon a Pass-Through Rate, the distribution formula for the
Certificates of a Class may entitle the holders thereof to distributions of
interest on specified Distribution Dates (which may include all or less than all
of the Distribution Dates) equal, in the case of any such Distribution Date, to
all or a portion (which portion will be determined as described in the related
Prospectus Supplement) of the interest payable on the related
 
                                       34
<PAGE>
Contracts during one or more Collection Periods occurring prior to such
Distribution Date. Classes of Certificates that do not entitle the holders
thereof to receive distributions of principal may nevertheless entitle such
holders to receive interest distributions calculated on this basis.
 
    If, due to liquidation losses or other circumstances adversely affecting the
collections on the underlying Contract Pool, the Contract collections available
to make distributions of interest to the holders of the Certificates of a Class
are less than the amount of interest computed as described above, the deficiency
may be made up from other sources, but only to the extent, if any, specified in
the applicable Prospectus Supplement. See "Credit and Liquidity Enhancement"
herein.
 
    Each Prospectus Supplement will contain information relating to the full
amounts of principal and interest required to be distributed to the holders of
the related Class or Classes of Certificates, to the extent there are sufficient
Contract collections available therefor (sometimes referred to herein as "full
distributions"), to the amounts paid or payable on the underlying Contracts.
 
    C.  RESIDUAL INTERESTS.  If specified in the related Prospectus Supplement,
a Class of Certificates sold hereunder may evidence a residual interest in the
related Trust Fund (the "Residual Interest"). Certificates evidencing a Residual
Interest will not have the features described above. Rather, unless otherwise
specified in such Prospectus Supplement, such Certificates will entitle the
holders thereof to receive distributions from amounts collected on the Contracts
which would not be needed to make distributions to the holders of other
interests in the Trust Fund (or to pay expenses of the Trust Fund) in the
absence of liquidation losses or other events resulting in deficient Contract
collections. In addition, if specified in such Prospectus Supplement, any such
Certificates may also entitle the holders thereof to receive additional
distributions of assets of the related Trust Fund, to the extent any such assets
remain after being applied to make distributions to the holders of other
interests in the Trust Fund (or to pay expenses of the Trust Fund). The
Certificates evidencing a Residual Interest may entitle the holders thereof to
distributions at various times throughout the life of the related Trust Fund or
only upon termination of the Trust Fund, all as more fully set forth in the
related Prospectus Supplement. If an election is made to treat the related Trust
Fund as a REMIC (as hereinafter defined), the holders of a Residual Interest in
such Trust Fund will be subject to federal income taxation with respect to their
ownership of such Residual Interest as described herein under "Certain Federal
Income Tax Consequences--REMIC Certificates--D. Taxation of Residual
Certificates."
 
GLOBAL CERTIFICATES
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Certificates of a Series, or of one or more Classes within a Series, will be
issuable in the form of one or more global certificates (each, a "Global
Certificate") that are initially registered in the name of Cede & Co. ("Cede"),
as nominee of The Depository Trust Company ("DTC"), on behalf of the beneficial
owners (the "Certificate Owners") of the Certificates. DTC is a limited-purpose
trust company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC accepts securities for
deposit from its participating organizations ("Participants") and facilitates
the clearance and settlement of securities transactions between Participants in
such securities through electronic book-entry changes in accounts of
Participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers, banks and
trust companies and clearing corporations and may include certain other
organizations. Indirect access to the DTC system is also available to others
such as banks, brokers, dealers and trust companies that clear through or
maintain a custodial relationship with a Participant, either directly or
indirectly ("Indirect Participants").
 
    Certificate Owners who are not Participants but desire to purchase, sell or
otherwise transfer ownership of Certificates may do so only through Participants
(unless and until Definitive Certificates are
 
                                       35
<PAGE>
issued). In addition, Certificate Owners will receive all distributions of
principal of, and interest on, the Certificates from the Trustee through DTC and
Participants. Certificate Owners will not receive or be entitled to receive
certificates representing their respective interests in the Certificates, except
under the limited circumstances described below. In addition, if some or all of
the Certificates of a Series are issued in the form of one or more Global
Certificates, certain monthly and annual reports prepared by the Servicer under
the related Agreement will be sent on behalf of the related Trust Fund to Cede
and not to the Certificate Owners.
 
    Unless and until Definitive Certificates are issued, it is anticipated that
the only "Certificateholder" of the Certificates will be Cede, as nominee of
DTC. Certificate Owners will not be Certificateholders as that term is used in
the Agreement. Certificate Owners are only permitted to exercise the rights of
Certificateholders indirectly through Participants and DTC.
 
    Unless otherwise specified in the related Prospectus Supplement, while the
Certificates are outstanding (except under the circumstances described below),
under the rules, regulations and procedures creating and affecting DTC and its
operations (the "DTC Rules"), Participants are required to make book-entry
transfers through DTC's facilities with respect to the Certificates, and DTC as
the sole holder of the Certificates is required to receive and transmit
distributions of principal of, and interest on, the Certificates. Unless and
until Definitive Certificates are issued, Certificate Owners who are not
Participants may transfer ownership of Certificates only through Participants by
instructing such Participants to transfer Certificates, by book-entry transfer,
through DTC for the account of the purchasers of such Certificates, which
account is maintained with their respective Participants. Under the DTC Rules
and in accordance with DTC's normal procedures, transfers of ownership of
Certificates will be executed through DTC, and the accounts of the respective
Participants at DTC will be debited and credited.
 
    Definitive Certificates will be issued to Certificate Owners, or their
nominees, rather than to DTC, only if (i) the Servicer advises the Trustee in
writing that DTC is no longer willing or qualified to discharge properly its
responsibilities as nominee and depository with respect to the Certificates and
the Servicer or the Trustee is unable to locate a qualified successor, (ii) the
Sellers, at their option, jointly elect to terminate the book-entry system
through DTC, or (iii) after the occurrence of an Event of Default (See
"--Servicing Compensation and Payment of Expenses; Certain Matters Regarding the
Servicer--Events of Default" below), Certificate Owners having a majority in
Percentage Interests of each Class of the Certificates advise the Trustee and
DTC through the Participants, in writing, that the continuation of a book-entry
system through DTC (or a successor thereto) to the exclusion of any physical
certificates being issued to Certificate Owners is no longer in the best
interests of Certificate Owners. Upon issuance of Definitive Certificates to
Certificate Owners, such Certificates will be transferable directly (and not
exclusively on a book-entry basis), and registered holders will deal directly
with the Trustee with respect to transfers, notices and distributions.
 
    Except as otherwise specified in the related Prospectus Supplement, unless
and until Definitive Certificates are issued, DTC will take any action permitted
to be taken by a Certificateholder under the Agreement only at the direction of
one or more Participants to whose DTC accounts the Certificates are credited and
will take such action with respect to any Percentage Interests of the
Certificates only at the direction of and on behalf of such Participants with
respect to such Percentage Interests of the Certificates. DTC may take actions,
at the direction of the related Participants, with respect to some Certificates
which conflict with actions taken with respect to other Certificates.
 
OPTIONAL AND MANDATORY REPURCHASE OF CERTIFICATES; OPTIONAL TERMINATION AND
  TERMINATION AUCTION
 
    A.  OPTIONAL REPURCHASE.  Unless otherwise specified in the applicable
Prospectus Supplement, the Servicer for any Trust Fund will have the option to
repurchase, upon giving notice mailed no later than the Distribution Date next
preceding the month of the exercise of such option, all outstanding Contracts
after the first Distribution Date on which the Pool Scheduled Principal Balance
(as defined hereinafter) is less
 
                                       36
<PAGE>
than 10% of the initial Pool Principal Balance on the Cut-off Date. The price at
which the Servicer for such Trust Fund may repurchase the related Contracts will
equal the greater of (a) the sum of (x) 100% of the Pool Scheduled Principal
Balance of each Contract (other than any Contract as to which the related
Manufactured Home has been acquired and not yet disposed of and whose fair
market value is included pursuant to clause (y) below) as of the final
Distribution Date, and (y) the fair market value of such acquired property (as
determined by the Servicer) and (b) the aggregate fair market value (as
determined by the Servicer) of all of the assets of such Trust Fund, plus, in
the case of both clause (a) and (b), an amount sufficient to reimburse
Certificateholders for each outstanding Class for any shortfall in interest due
thereto in respect of prior Distribution Dates. Notwithstanding the foregoing,
the Servicer's option shall not be exercisable if there will not be distributed
to the Certificateholders for each outstanding Class an amount equal to the
aggregate Certificate Balance for each outstanding Class together with any
shortfall in interest due to such Certificateholders in respect of prior
Distribution Dates and one month's interest on the aggregate Certificate Balance
for each outstanding Class at the respective Pass-Through Rates for such Classes
(the "Minimum Termination Amount"). See "Description of the Certificates--
Optional Termination" in the related Prospectus Supplement. (Section 10.01.)
 
    B.  MANDATORY REPURCHASE.  Some or all of the Certificates of a Class may be
subject to repurchase by or on behalf of the Sellers at the option of the
holders thereof and/or at the option of the Sellers, but only to the extent, at
the prices, on the dates and under the conditions specified in the related
Prospectus Supplement. In addition, some or all of the Certificates of a Class
may be subject to mandatory repurchase by or on behalf of the Sellers to the
extent, at the prices, on the dates and under the conditions specified in the
related Prospectus Supplement. On the date on which any Certificate is subject
to repurchase (the "Repurchase Date") the holder thereof will cease to be
entitled to any benefit of the Certificate or the related Agreement and will be
entitled only to receive from the Trustee the repurchase price of the
Certificate upon surrender thereof at the office or agency designated by the
Trustee. To the extent specified in the related Prospectus Supplement, the funds
necessary to distribute the repurchase price of any Certificate subject to
mandatory or optional repurchase as described therein will be provided under a
certificate purchase agreement or other Liquidity Facility as described in
"Credit and Liquidity Enhancement" herein.
 
                                       37
<PAGE>
    C.  OPTIONAL OR MANDATORY TERMINATION AUCTION.  If specified in the
applicable Prospectus Supplement, on any Distribution Date after the
Distribution Date on which the Pool Scheduled Principal Balance is less than 10%
of the Cut-off Date Pool Principal Balance, the Servicer will, in addition to
the option to repurchase the Contracts discussed above, have the option to
direct the Trustee to solicit bids for the purchase at an auction (the
"Termination Auction") of the Contracts remaining in the Trust Fund. Unless the
Servicer has either exercised the option to repurchase the Contracts or directed
the Trustee to conduct a Termination Auction within 90 days of the Distribution
Date on which the Pool Scheduled Principal Balance is less than 10% of the
Cut-off Date Pool Principal Balance, the Servicer shall, to the extent specified
in the related Prospectus Supplement, be obligated to direct the Trustee to
conduct such a Termination Auction. In any Termination Auction, the Servicer
shall give notice as specified in the applicable Prospectus Supplement before
the date on which the Termination Auction is to occur. The Trustee will solicit
each Certificateholder, the Sellers and one or more active participants in the
asset-backed securities or manufactured housing contract market that are not
affiliated with BankAmerica Corporation to make a bid to purchase the Contracts
at the Termination Auction. The Trustee will sell all the Contracts to the
highest bidder, subject, among other things, to: (i) the requirement that the
highest bid equal or exceed the Minimum Termination Amount, and (ii) the
requirement that at least one bid be tendered by an active participant in the
asset-backed securities or manufactured housing contract market that is not
affiliated with BankAmerica Corporation. If the foregoing requirements are
satisfied, the successful bidder or bidders shall deposit the aggregate purchase
price for the Contracts in the Certificate Account. If the foregoing
requirements are not satisfied, the purchase shall not occur and distributions
will continue to be made on the Certificates. Any sale and consequent
termination of the Trust Fund as a result of a Termination Auction must
constitute a "qualified liquidation" of the Trust Fund under Section 860F of the
Code. (Section 10.1)
 
TERMINATION OF THE AGREEMENT
 
    The Agreement will terminate upon the last action required to be taken by
the Trustee on the final Distribution Date following the earlier of (i) the
purchase or sale of all Contracts and all property acquired in respect of any
Contract remaining in the Trust Fund as described above under "--Optional and
Mandatory Repurchase of Certificates; Termination Auction" or (ii) the final
payment or other liquidation (or any advance with respect thereto) of the last
Contract remaining in the relevant Trust Fund (including the disposition of all
property acquired upon repossession of any Manufactured Home). (Section 10.01.)
 
    In the event of the termination of any Agreement, the holders of
Certificates of any Class of the related Series will be entitled to receive,
upon presentation and surrender of their Certificates at the office or agency
designated by the Trustee, a final distribution in an amount computed as
described in the related Prospectus Supplement.
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
    Except as otherwise provided in the related Agreement, the Servicer may
rescind, cancel or make material modifications of the terms of a Contract
(including modifying the amounts and Due Dates of Scheduled Payments) in
connection with a default or imminent default thereunder. However, unless
otherwise specified in the related Prospectus Supplement and unless required by
the applicable law or to bring Contracts into conformity with the
representations and warranties contained in the Agreement, the Servicer may not
rescind, cancel or materially modify any Contract unless the Servicer obtains an
opinion of counsel to the effect that such action will not have certain adverse
federal income tax consequences. (Section 4.07.)
 
                                       38
<PAGE>
SERVICING COMPENSATION AND PAYMENT OF EXPENSES; CERTAIN MATTERS REGARDING THE
  SERVICER
 
    The monthly servicing fee (the "Monthly Servicing Fee") and any additional
servicing compensation with respect to the Contracts underlying a Series of
Certificates will be specified in the applicable Prospectus Supplement. (Section
1.01.)
 
    The Monthly Servicing Fee provides compensation for customary manufactured
housing contract third-party servicing activities to be performed by the
Servicer for the Trust Fund and for additional administrative services performed
by the Servicer on behalf of the Trust Fund. Customary servicing activities
include collecting and recording payments, communicating with Obligors,
investigating payment delinquencies, providing billing and tax records to
Obligors and maintaining internal records with respect to each Contract.
Administrative services performed by the Servicer on behalf of the Trust Fund
include calculating distributions to Certificateholders and providing related
data processing and reporting services for Certificateholders and on behalf of
the Trustee. Unless otherwise specified in the applicable Prospectus Supplement,
expenses incurred in connection with servicing the Contracts and paid by the
Servicer from its Monthly Servicing Fee include, without limitation, payment of
fees and expenses of accountants, payment of all fees and expenses incurred in
connection with the enforcement of Contracts (except liquidation expenses and
certain other expenses) and payment of expenses incurred in connection with
distributions and reports to Certificateholders. The Servicer will be reimbursed
out of the liquidation proceeds from a defaulted Contract for all reasonable,
out-of-pocket liquidation expenses incurred by it in realizing upon the related
Manufactured Home as well as for advances of taxes and insurance premiums
previously made with respect to any such Contract (to the extent not previously
recovered).
 
    Unless otherwise specified in the related Prospectus Supplement, as part of
its servicing fees, the Servicer will also be entitled to retain, as
compensation for the additional services provided in connection therewith, any
fees for late payments made by Obligors, extension fees paid by Obligors for the
extension of scheduled payments and assumption fees for permitted assumptions of
Contracts by purchasers of the related Manufactured Homes. (Sections 4.15 and
5.03.) To the extent specified in the related Prospectus Supplement, the
Servicer will also be entitled to use payments of principal and interest
(including Liquidation Proceeds net of Liquidation Expenses) for its own
benefit, without an obligation to pay interest or any other investment return
thereon, until the related Distribution Date.
 
    Unless otherwise specified in the applicable Prospectus Supplement, any
person with which the Servicer is merged or consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Servicer is
a party, or any person succeeding to the business of the Servicer, will be the
successor to the Servicer under the Agreement, so long as such successor has a
net worth of at least $50 million and has serviced at least $100 million of
manufactured housing contracts for at least one year. The Servicer may assign
its rights and delegate its duties under the Agreement (whereupon it will no
longer be liable for the obligations of the Servicer under the Agreement),
provided that, among other conditions, any rating assigned to the Certificates
will not be reduced because of such assignment and delegation. (Sections 7.04,
7.06 and 7.07.)
 
    A.  HAZARD INSURANCE POLICIES.  Unless otherwise specified in the related
Prospectus Supplement, the Servicer will be obligated to cause to be maintained
one or more hazard insurance policies with respect to each Manufactured Home in
an amount at least equal to the lesser of its maximum insurable value or the
principal amount due from the Obligor under the related Contract. Such hazard
insurance policies will, at a minimum, provide fire and extended coverage on
terms and conditions customary in manufactured housing hazard insurance
policies. If a Manufactured Home is located within a federally designated flood
area, the Servicer will, to the extent required by applicable law or regulation,
also be obligated to cause flood insurance to be maintained in an amount equal
to the lesser of the amounts described above or the maximum amount available for
such Manufactured Home under the federal flood insurance programs. Such policies
may provide for customary deductible amounts. Coverage thereunder will be
required to be sufficient to avoid the application of any co-insurance
provisions. Such policies will be required to contain
 
                                       39
<PAGE>
a standard loss payee clause in favor of the Servicer and its successors and
assigns. In general, the Servicer will not be obligated to cause to be obtained
and maintained hazard insurance policies that provide earthquake coverage. If
earthquake coverage is required with respect to Contracts in a particular Trust
Fund, that fact will be disclosed in the related Prospectus Supplement.
 
    Unless otherwise specified in the related Prospectus Supplement, all amounts
collected by the Servicer under a hazard or flood insurance policy will be
applied either to the restoration or repair of the Manufactured Home or against
the remaining principal balance of the related Contract upon repossession of the
Manufactured Home, after reimbursing the Servicer for amounts previously
advanced by it for such purposes. The Servicer may satisfy its obligation to
maintain hazard and flood insurance policies with respect to each Manufactured
Home by maintaining a blanket policy insuring against hazard and flood losses on
the related Obligor's interest in such Manufactured Home. Such blanket policy
may contain a deductible clause, in which case the Servicer will be required to
make payments to the related Trust Fund in the amount of any deductible amounts
in connection with insurance claims on repossessed Manufactured Homes.
 
    Unless otherwise specified in the related Prospectus Supplement, if the
Servicer repossesses a Manufactured Home on behalf of the Trustee, the Servicer
is required to either maintain a Hazard Insurance Policy with respect to such
Manufactured Home meeting the requirements set forth above, or to indemnify the
Trust Fund against any damage to such Manufactured Home prior to resale or other
disposition. (Section 4.09.)
 
    B.  EVIDENCE AS TO COMPLIANCE.  Unless otherwise specified in the related
Prospectus Supplement, the Servicer will be required to deliver to the Trustee
each year an officer's certificate executed by an officer of the Servicer (i)
stating that a review of the activities of the Servicer during the preceding
calendar year and of performance under the Agreement has been made under the
supervision of such officer, and (ii) stating that to the best of such officer's
knowledge, the Servicer has fulfilled all its obligations under the Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officer and the
nature and status thereof. Such officer's certificate will be accompanied by a
statement of a firm of independent public accountants to the effect that, on the
basis of an examination of certain documents and records relating to servicing
of the Contracts under the Agreement (or, at the Servicer's option, the
Contracts and other contracts being serviced by the Servicer under agreements
similar to the Agreement), conducted in accordance with generally accepted
auditing standards, the Servicer's servicing has been conducted in compliance
with the provisions of the Agreement (or such agreements), except (i) such
exceptions as such firm believes to be immaterial and (ii) such other exceptions
as may be set forth in such statement. (Sections 4.20 and 4.21.)
 
    C.  EVENTS OF DEFAULT.  Unless otherwise specified in the related Prospectus
Supplement, events of default under the Agreement will consist of (i) any
failure by the Servicer to make any deposit or payment required of it under the
Agreement which continues unremedied for five days after the giving of written
notice, (ii) any failure by the Servicer duly to observe or perform in any
material respect any of its other covenants or agreements in the Agreement which
continues unremedied for 30 days after the giving of written notice of such
failure, and (iii) certain events of insolvency, readjustment of debt,
marshaling of assets and liabilities or other similar proceedings regarding the
Servicer. Unless otherwise specified in the related Prospectus Supplement,
"notice" as used in this paragraph means notice to the Servicer by the Trustee,
the Sellers or, if applicable, the Credit Facility Provider, or to the Servicer,
the Trustee and the Sellers by the holders of Certificates evidencing interests
("Fractional Interests") in the outstanding principal balance of outstanding
Certificates that, in the aggregate, equal at least 25% of the principal balance
of all outstanding Certificates (excluding Certificates held by the Sellers,
Bank of America, FSB, through its division, BankAmerica Housing Services (as
well as any successor Servicer, if Bank of America, FSB is not the Servicer) or
any of their respective affiliates). (Section 8.01.)
 
                                       40
<PAGE>
    D.  RIGHTS UPON EVENT OF DEFAULT.  Unless otherwise specified in the related
Prospectus Supplement so long as an event of default remains unremedied, the
Trustee may (but only with the consent of the Credit Facility Provider (if any)
if the Credit Facility has not expired or if the Credit Facility has expired or
been terminated and such Credit Facility Provider has not been reimbursed for
all amounts due it), and at the written direction of the holders of Certificates
evidencing Fractional Interests aggregating not less than 51% shall, terminate
all of the rights and obligations of the Servicer under the Agreement and in and
to the related Contracts, whereupon (subject to applicable law regarding the
Trustee's ability to make monthly advances) the Trustee or a successor Servicer
under the Agreement will succeed to all the responsibilities, duties and
liabilities of the Servicer under the Agreement and will be entitled to similar
compensation arrangements. If the Trustee is obligated to succeed the Servicer
but is unwilling or unable so to act, it may appoint, or petition a court of
competent jurisdiction for the appointment of, a Servicer. Pending such
appointment, the Trustee is obligated to act in such capacity. The Trustee and
such successor may agree upon the servicing compensation to be paid, which in no
event may be greater than a monthly amount specified in the Agreement. (Sections
7.07 and 8.01.)
 
    Unless otherwise specified in the related Prospectus Supplement, no
Certificateholder will have any right under the Agreement to institute any
proceeding with respect to the Agreement unless such holder previously has given
to the Trustee written notice of default and unless the holders of Certificates
evidencing Fractional Interests aggregating not less than 25% have requested the
Trustee in writing to institute such proceeding in its own name as Trustee and
have offered to the Trustee reasonable indemnity and the Trustee for 60 days has
neglected or refused to institute any such proceeding. The Trustee will be under
no obligation to take any action or institute, conduct or defend any litigation
under the Agreement at the request, order or direction of any of the holders of
Certificates, unless such Certificateholders have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which the Trustee may incur. (Sections 8.01 and 11.08.)
 
AMENDMENT
 
    Unless otherwise specified in the related Prospectus Supplement, the
Agreement may be amended by the Sellers, the Servicer and the Trustee without
the consent of the Certificateholders (but only with the consent of the Credit
Facility Provider (if any) if the Credit Facility has not expired or if the
Credit Facility has expired or been terminated and such Credit Facility Provider
has not been reimbursed for all amounts due it), (i) to cure any ambiguity, (ii)
to correct or supplement any provision therein that may be inconsistent with any
other provision therein, (iii) to add to the duties or obligations of the
Servicer, (iv) to obtain a rating from a nationally recognized rating agency or
to maintain or improve the ratings of any Class of the Certificates then given
by any rating agency (it being understood that, after obtaining the rating of
the Certificates from the rating agencies specified in such Agreement, none of
the Trustee, the Sellers or the Servicer is obligated to obtain, maintain or
improve any rating assigned to the Certificates), or (v) to make any other
provisions with respect to matters or questions arising under such Agreement,
provided that such action will not, as evidenced by an opinion of counsel,
adversely affect in any material respect the interests of the
Certificateholders. The Agreement may also be amended, by the Sellers, the
Servicer and the Trustee with the consent of at least 51% of the holders of
Certificates of each Class affected thereby for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
such Agreement or of modifying in any manner the rights of the
Certificateholders; provided, however, that no such amendment shall (i) reduce
in any manner the amount of, or delay the timing of, any distributions on any
Certificate, without the consent of the Holder of such Certificate as the case
may be, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in (i),
without the consent of the Holders of Certificates of such Class evidencing, as
to such Class, Percentage Interests aggregating 66% or (iii) reduce the
aforesaid percentage of Certificates the holders of which are required to
consent to any such amendment, without the consent of the holders of all
Certificates then outstanding, and no such amendment shall adversely affect the
status of the Trust Fund as a REMIC.
 
                                       41
<PAGE>
    Unless otherwise specified in the applicable Prospectus Supplement, the
Agreement may also be amended from time to time, without the consent of any
Certificateholders, by the Sellers, the Trustee and the Servicer to modify,
eliminate or add to the provisions of the Agreement to (i) maintain the
qualification of the Trust Fund as a REMIC under the Code or avoid, or minimize
the risk of, the imposition of any tax on the Trust Fund under the Code that
would be a claim against the Trust Fund assets, provided that an opinion of
counsel is delivered to the Trustee to the effect that such action is necessary
or appropriate to maintain such qualification or avoid any such tax or minimize
the risk of its imposition, or (ii) prevent the Trust Fund from entering into
any "prohibited transaction" as defined in Section 860F of the Code, provided
that an opinion of counsel is delivered to the Trustee to the effect that such
action is necessary or appropriate to prevent the Trust Fund from entering into
such prohibited transaction. (Section 11.01.)
 
    The Agreement may otherwise be subject to amendment without the consent of
any Certificateholders and, under certain circumstances, without the consent of
the Trustee, if and to the extent specified in the related Prospectus
Supplement.
 
THE TRUSTEE
 
    The Trustee with respect to a Series will be identified in the applicable
Prospectus Supplement. Unless otherwise specified therein, the Trustee may
resign at any time, in which event the Sellers will be obligated to appoint a
successor Trustee. The Sellers may also remove the Trustee if the Trustee ceases
to be eligible to continue as such under the related Agreement or if the Trustee
becomes insolvent. In such circumstances, the Sellers will also be obligated to
appoint a successor Trustee. Any resignation or removal of the Trustee and
appointment of a successor Trustee will not become effective until acceptance of
the appointment by the successor Trustee. (Section 9.07.)
 
    Unless otherwise specified in the related Prospectus Supplement, the
Agreement for any Series will require the Trustee to maintain, at its own
expense, an office or agency in New York City where the Certificates for such
Series may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Trustee and the Certificate Registrar in
respect of such Certificates pursuant to the related Agreement may be served.
Unless otherwise specified in the related Prospectus Supplement, the Trustee, or
any of its affiliates, in its individual or any other capacity, may become the
owner or pledgee of the Certificates of any Series with the same rights as it
would have if it were not Trustee.
 
    Unless otherwise specified in the related Prospectus Supplement, the Trustee
will act as Paying Agent, Certificate Registrar and Authenticating Agent for the
related Series of Certificates.
 
INDEMNIFICATION
 
    Unless otherwise specified in the applicable Prospectus Supplement, each
Agreement will provide that neither the Servicer nor any of its directors,
officers, employees or agents will be under any liability to the Trustee or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to such Agreement, or for errors in judgment;
provided, however, that such provision shall not protect the Servicer or any
such person against any liability that would otherwise be imposed by reason of
willful misfeasance, bad faith or gross negligence. The Servicer shall not be
under any obligation to appear in, prosecute or defend any legal action which
arises under an Agreement (other than in connection with the enforcement of any
Contract in accordance with the Agreement) and which in its opinion may involve
it in any expenses or liability; provided, however, that the Servicer may in its
discretion undertake any such other legal action which it may deem necessary or
desirable in respect of the Agreement and the rights and duties of the parties
thereto. In such event, the legal expenses and costs of such other legal action
and any liability resulting therefrom shall be expenses, costs and liabilities
payable from the Trust Fund and the Servicer shall be entitled to be reimbursed
therefor from amounts collected on the Contracts. (Section 7.05.)

                        CREDIT AND LIQUIDITY ENHANCEMENT
 
    To the extent specified in the related Prospectus Supplement, a Class of
Certificates may be entitled to the benefit of one or more of the following
forms of credit and liquidity enhancement:
 
SUBORDINATION
 
    The Certificates of one or more Classes of a multiple-Class Series (the
"Senior Certificates") may afford the holders thereof a right to receive
distributions of principal or of interest or of both on each Distribution Date
from amounts collected on the related Contract Pool that is prior to the right
to receive such distributions afforded by the Certificates of the other Class or
Classes (the "Junior Certificates" or "Subordinate Certificates"). Unless
otherwise specified in the related Prospectus Supplement, this prior right will
result from one or both of the following two features:
 
        1.  The Senior Certificates will entitle the holders thereof to receive
    on some or all Distribution Dates, prior to any distribution of principal or
    of interest or of both (as specified in the related Prospectus Supplement)
    being made to the holders of the Junior Certificates on any such
    Distribution Date, a full distribution of principal or of interest or of
    both principal and interest (as specified in the related Prospectus
    Supplement) from amounts collected on the Contracts during the related
    Collection Period(s). To the extent that Contract collections during the
    related Collection Period(s) would, in the absence of liquidation losses or
    other circumstances adversely affecting such Contract collections, have been
    applied to make distributions to the holders of the Junior Certificates,
    this feature will enhance the likelihood of timely receipt by the holders of
    the Senior Certificates of full distributions of principal or of interest or
    of both in accordance with the applicable distribution formula.
 
        2.  The distribution formula for the Senior Certificates (other than
    interest-only Certificates) will entitle the holders thereof to receive, on
    some or all Distribution Dates, all or a disproportionate share of the Total
    Regular Principal Amount until the Certificate Balance of the Senior
    Certificates has been reduced to zero. See "Description of
    Certificates--Distributions on Certificates--A. Distributions of Principal"
    above. This feature, in effect, will provide the holders of the Senior
    Certificates (other than holders of interest-only Certificates) with a prior
    right to receive the principal collected on the Contracts until the
    Certificate Balance of the Senior Certificates has been reduced to zero. The
    degree of priority will depend on the share of the Total Regular Principal
    Amount to which the holders of the Senior Certificates (other than holders
    of interest-only Certificates) are entitled on particular Distribution
    Dates. If the holders of the Senior Certificates (other than holders of
    interest-only Certificates) are entitled to receive all of the Total Regular
    Principal Amount on each Distribution Date (to the extent of the Contract
    collections available to make distributions of Regular Principal on such
    Distribution Date), then the holders of the Senior Certificates (other than
    holders of interest-only Certificates) will, in effect, have a right to
    receive all principal collected on the Contracts that is absolutely prior to
    the right of the holders of the Junior Certificates to receive any principal
    collected on the Contracts. If, however, the holders of the Senior
    Certificates (other than holders of interest-only Certificates) are entitled
    to receive only a disproportionate share of the Total Regular Principal
    Amount, or are entitled to receive all or a disproportionate share of the
    Total Regular Principal Amount only on certain Distribution Dates, then the
    prior right of the holders of the Senior Certificates (other than holders of
    interest-only Certificates) to receive distributions of principal collected
    on the Contracts will, to that extent, be limited. The prior right to
    receive distributions of principal collections described above will enhance
    the likelihood that the holders of the Senior Certificates (other than
    holders of interest-only Certificates) will ultimately receive distributions
    of principal in an aggregate amount equal to the initial Certificate Balance
    of the Senior Certificates. It will not, however, enhance the likelihood of
    timely receipt by the holders of the Senior Certificates of full
    distributions of the amounts to which they would have been entitled in the
    absence of liquidation losses or other circumstances adversely affecting
    Contract collections.
 
                                       43
<PAGE>
    If specified in the related Prospectus Supplement, the features described
above may be characteristic of different Classes within a multiple-Class Series.
Thus, Certificates which constitute Senior Certificates under the criteria
described in paragraph 1 above may constitute Junior Certificates under the
criteria described in paragraph 2 above, and Certificates which constitute
Senior Certificates under the criteria described in paragraph 2 above may
constitute Junior Certificates under the criteria described in paragraph 1
above. In general, the splitting of the features described above among two
separate Classes of a multiple-Class Series will undercut the protection against
loss afforded by each of such features. The particular effects of any such
splitting will be discussed in the applicable Prospectus Supplement. The
following discussion is based on the assumption that the features described
above will not be characteristic of different Classes within a multiple-Class
Series.
 
    The degree of protection against loss provided to the holders of the Senior
Certificates at any time by either of the subordination features described above
will be determined primarily by the degree to which the aggregate principal
balance of the underlying Contracts (the "Pool Principal Balance") exceeds the
Certificate Balance of the Senior Certificates (and to a lesser extent, if the
holders of the Senior Certificates also have a prior right to receive interest,
by the degree to which the interest payable on the Contracts, net of the
portions thereof used to pay the servicing fee of the Servicer (if such
servicing fee is payable prior to distributions of interest to the holders of
the Senior Certificates) and other expenses of the Trust Fund, exceeds the
interest distributable to the holders of the Senior Certificates). The relative
levels of the Certificate Balance of the Senior Certificates (the "Senior
Certificate Balance") and the related Pool Principal Balance, and hence the
degree of protection against loss afforded by the subordination features
described above, may change over time depending on, among other things, the
formula by which principal is distributed to the holders of the Senior
Certificates and the level of liquidation losses on the underlying Contracts.
Generally, if the holders of Senior Certificates (other than holders of
interest-only Certificates) receive a disproportionate share of the Total
Regular Principal Amount on any Distribution Date, the effect will be to
increase, as a relative matter, the degree by which the Pool Principal Balance
exceeds the Certificate Balance of the Senior Certificates, thus increasing the
degree of protection against loss afforded by the subordination of the Junior
Certificates. In addition, Special Principal Distributions to the holders of the
Senior Certificates from sources other than principal collections on the
underlying Contracts generally will increase the degree of protection against
loss above the protection that would have been provided if such distributions
were not made (because the Senior Certificate Balance will be reduced without a
reduction in the Pool Principal Balance). On the other hand, if, due to
liquidation losses or other circumstances adversely affecting Contract
collections, the holders of Senior Certificates (other than holders of
interest-only Certificates) receive less than their proportionate share of the
Total Regular Principal Amount, the effect will be to decrease, as a relative
matter, the degree to which the Pool Principal Balance exceeds the Certificate
Balance of the Senior Certificates, thus decreasing the degree of protection
against loss afforded by the subordination of the Junior Certificates. The
effects of particular principal distribution formulae in this regard will be
discussed in the applicable Prospectus Supplement. The description of any such
effects in a particular Prospectus Supplement may relate the Certificate
Balances of the Senior Certificates to Pool Principal Balances which are
estimated or adjusted as described therein. Such Pool Principal Balances may
sometimes be referred to in a Prospectus Supplement as "Pool Scheduled Principal
Balances."
 
    Where there is more than one Class of Junior Certificates, the rights of one
or more of such Classes of Junior Certificates to receive distributions of
principal, interest or principal and interest may be subordinated to the rights
of one or more other Classes of Junior Certificates to receive such
distributions. Any Class of Junior Certificates that is entitled to receive such
distributions from Contract Pool collections prior to any other Class of Junior
Certificates is a "mezzanine" Class of Junior Certificates. The subordination of
any Class of Junior Certificate to a mezzanine Class of Junior Certificates will
enhance the likelihood of timely receipt by the holders of such mezzanine Class
of Junior Certificates relative to any Class of Junior Certificates that is
subordinate to such mezzanine Class of Junior Certificates. Junior Certificates,
including any mezzanine Classes of Junior Certificates, may only be sold
hereunder if rated in
 
                                       44
<PAGE>
one of the four highest rating categories of a nationally recognized statistical
rating organization. (See "Rating" herein). The effect of any subordination on
any Classes of Junior Certificates sold hereunder will be discussed in the
applicable Prospectus Supplement.
 
RESERVE FUNDS
 
    The Certificates of one or more Classes may be entitled to the benefit of
one or more spread accounts or other reserve funds (each, a "Reserve Fund")
which, to the extent specified in the related Prospectus Supplement, will cover
shortfalls created when collections on the related Contract Pool that are
available to make distributions to the holders of such Certificates are not
sufficient to fund full distributions of principal, interest or principal and
interest to such Certificateholders. Any Reserve Fund may be available to cover
all or a portion of such shortfalls and may be available to cover any
shortfalls, no matter what the cause, or only shortfalls due to certain causes
(e.g., liquidation losses only or delinquencies only), all as specified in the
related Prospectus Supplement. In addition, to the extent specified in the
related Prospectus Supplement, a Reserve Fund may be used to make distributions
of interest or Regular Principal to the holders of a Class of Certificates on
particular Distribution Dates upon the occurrence of certain losses,
delinquencies or other events, even if such Certificateholders would not have
been entitled to any such distributions on such Distribution Dates in the
absence of losses, delinquencies or other events. A Reserve Fund may also be
used to fund Special Principal Distributions under the circumstances set forth
in the related Prospectus Supplement. The related Prospectus Supplement will
specify whether any Reserve Fund will be established as part of the Trust Fund
or held outside of the Trust Fund by a collateral agent or similar third party
(who may be the Trustee acting in a different capacity) and will contain a
description of any arrangement pursuant to which the Reserve Fund is held
outside of the Trust Fund.
 
    The method of funding any Reserve Fund, and the required levels of funding,
if any, as well as the circumstances under which amounts on deposit in any
Reserve Fund may be distributed to persons other than Certificateholders, will
be described in the applicable Prospectus Supplement. To the extent that a
Reserve Fund may be funded in whole or in part from some or all of the interest
collected on the Contracts in excess of the interest needed to make
distributions to the holders of one or more Classes of Certificates, such
Reserve Fund may be referred to in the applicable Prospectus Supplement as a
"Spread Account."
 
CREDIT FACILITIES
 
    The Certificates of one or more Classes may be entitled to the benefit of
one or more letters of credit, surety bonds or similar credit facilities (each,
a "Credit Facility"). Each such Credit Facility may be in an amount greater
than, equal to or less than the Certificate Balance of the Certificates of each
Class entitled to the benefits thereof, and may be subject to reduction or be
limited as to duration, all as described in the applicable Prospectus
Supplement. To the extent specified in the related Prospectus Supplement,
amounts realized under a Credit Facility supporting the Certificates of any
Class may be used for the same purposes as amounts on deposit in Reserve Funds.
See "--Reserve Funds" above. A Credit Facility may be held by a Trustee as part
of the related Trust Fund or may be held by a collateral agent or other third
party (who may be the Trustee acting in a different capacity). The related
Prospectus Supplement will contain a description of the material terms of any
Credit Facility and any arrangement pursuant to which the Credit Facility is
held outside of the Trust Fund. Such Prospectus Supplement will also contain
certain information concerning the provider of the Credit Facility (the "Credit
Facility Provider"), which information will have been provided to the Sellers by
the Credit Facility Provider for use in such Prospectus Supplement. Bank of
America, Bank of America, FSB or an affiliate thereof may be a Credit Facility
Provider.
 
    If specified in the applicable Prospectus Supplement, a Credit Facility,
rather than supporting distributions of particular amounts to the holders of
Certificates of particular Classes, may, instead, support certain collections on
the related Contract Pool. These collections may be of all or a portion of
amounts due on Contracts in liquidation, all or a portion of the scheduled
monthly payments due on the
 
                                       45
<PAGE>
Contracts or of other amounts. The extent to which any such collections are
supported by a Credit Facility which functions in this manner will be described
in the applicable Prospectus Supplement.
 
LIQUIDITY FACILITIES
 
    The Certificates of one or more Classes may be entitled to the benefit of
one or more certificate purchase agreements or other liquidity facilities (each,
a "Liquidity Facility"), pursuant to which the provider of such Liquidity
Facility (the "Liquidity Facility Provider") will provide funds to be used to
purchase some or all of such Certificates on the Repurchase Dates applicable
thereto. Unless otherwise specified in the applicable Prospectus Supplement, a
Liquidity Facility will be held outside of the Trust Fund by a third party
(which may be the Trustee acting in another capacity). The related Prospectus
Supplement will contain a description of the material terms of any such
Liquidity Facility and any arrangement pursuant to which it is held outside of
the Trust Fund, and will contain certain information concerning the Liquidity
Facility Provider, which information will have been provided to the Sellers by
the Liquidity Facility Provider for use in such Prospectus Supplement. Bank of
America, Bank of America, FSB or an affiliate thereof may be a Liquidity
Facility Provider. If specified in the related Prospectus Supplement, a Reserve
Fund or Credit Facility may also serve as a Liquidity Facility.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following general discussion of the anticipated material federal income
tax consequences of the purchase, ownership and disposition of Certificates of
any Series, to the extent it relates to matters of law or legal conclusions with
respect thereto, represents the opinion of special counsel to Bank of America
and Bank of America, FSB with respect to that Series on the material matters
associated with such consequences, subject to any qualifications set forth
herein. Special counsel to Bank of America and Bank of America, FSB for each
Series will be Orrick, Herrington & Sutcliffe LLP, and a copy of the legal
opinion of such counsel rendered in connection with any Series of Certificates
will be filed with the Commission on a Current Report on Form 8- K within 15
days after the issuance of the related Series of Certificates. This discussion
is directed primarily to Certificateholders that hold the Certificates as
"capital assets" within the meaning of Section 1221 of the Code (although
portions thereof also may apply to Certificateholders who do not hold
Certificates as "capital assets") and it does not purport to discuss all federal
income tax consequences that may be applicable to the individual circumstances
of particular investors, some of which (such as banks, insurance companies and
foreign investors) may be subject to special treatment under the Code. Further,
the authorities on which this discussion, and the opinion referred to below, are
based are subject to change or differing interpretations, which could apply
retroactively. Prospective investors should note that no rulings have been or
will be sought from the Internal Revenue Service (the "Service") with respect to
any of the federal income tax consequences discussed below, and no assurance can
be given that the Service will not take contrary positions. Taxpayers and
preparers of tax returns (including those filed by any REMIC or other issuer)
should be aware that under applicable Treasury regulations a provider of advice
on specific issues of law is not considered an income tax return preparer unless
the advice (i) is given with respect to events that have occurred at the time
the advice is rendered and is not given with respect to the consequences of
contemplated actions, and (ii) is directly relevant to the determination of an
entry on a tax return. Accordingly, taxpayers should consult their tax advisors
and tax return preparers regarding the preparation of any item on a tax return,
even where the anticipated tax treatment has been discussed herein. In addition
to the federal income tax consequences described herein, potential investors are
advised to consider the state, local and other tax consequences, if any, of the
purchase, ownership and disposition of Certificates in a Series. See "Other Tax
Consequences." Certificateholders are advised to consult their tax advisors
concerning the federal, state, local or other tax consequences to them of the
purchase, ownership and disposition of Certificates in a Series.
 
    The following discussion addresses securities of two general types: (i)
certificates ("REMIC Certificates") representing interests in a Trust Fund with
respect to which an election to be treated as a "real
 
                                       46
<PAGE>
estate mortgage investment conduit" ("REMIC") under Sections 860A through 860G
(the "REMIC Provisions") of the Code will be made, and (ii) Grantor Trust
Certificates representing interests in a Trust Fund ("Grantor Trust Fund") as to
which no such election will be made.
 
    The following discussion is based in part upon the rules governing original
issue discount that are set forth in Sections 1271-1273 and 1275 of the Code and
in the Treasury regulations issued thereunder (the "OID Regulations"), and in
part upon the REMIC Provisions and the Treasury regulations issued thereunder
(the "REMIC Regulations"). The OID Regulations do not adequately address certain
issues relevant to, and in some instances provide that they are not applicable
to, securities such as the Certificates.
 
    The following discussion is limited in applicability to the Certificates.
For purposes of this tax discussion, references to a "Certificateholder" or a
"holder" are to the beneficial owner of a Certificate.
 
REMIC ELECTIONS
 
    Under the Code, an election may be made with respect to a Trust Fund related
to any Series of Certificates to treat such Trust Fund as a "real estate
mortgage investment conduit" ("REMIC") within the meaning of Section 860D(a) of
the Code, in which case the Certificates of any Class of such Series will be
either "regular interests" in the REMIC within the meaning of Section 860G(a)(1)
of the Code or "residual interests" in the REMIC within the meaning of Section
860G(a)(2) of the Code. The Prospectus Supplement for each Series of
Certificates will indicate whether each Seller of Contracts to the related
Contract Pool intends to cause an election to be made to treat the Trust Fund as
a REMIC, and if such an election is to be made, which Certificates will be
regular interests and which will be the residual interest in the REMIC. The
discussion under the heading "--REMIC Certificates" discusses Series with
respect to which each Seller of Contracts to the related Contract Pool will
cause a REMIC election to be made and the discussion under the heading
"--Non-REMIC Certificates" discusses Series with respect to which the Sellers
(or if only one Seller sells Contracts to the related Contract Pool, the
applicable Seller) will not cause a REMIC election to be made.
 
REMIC CERTIFICATES
 
    The discussion in this section applies only to a Series of Certificates for
which a REMIC election is to be made. Upon the issuance of each Series of
Certificates for which a REMIC election is to be made, Orrick, Herrington &
Sutcliffe LLP, special counsel to Bank of America and Bank of America, FSB, will
deliver its opinion generally to the effect that, with respect to each such
Series of Certificates, under then existing law and assuming that a REMIC
election is made in accordance with the requirements of the Code and compliance
by the Seller(s), the Servicer and the Trustee for such Series with all of the
provisions of the related Agreement, the agreement or agreements, if any,
providing for a Credit Facility or a Liquidity Facility, together with any
agreement documenting the arrangement through which a Credit Facility or a
Liquidity Facility is held outside the related Trust Fund, and agreement or
agreements with any Underwriter, the Trust Fund will be a REMIC, and the
Certificates of such Series will be treated as either "regular interests" in the
REMIC ("Regular Certificates") or "residual interests" in the REMIC ("Residual
Certificates") .
 
    The following general discussion of the anticipated federal income tax
consequences of the purchase, ownership and disposition of REMIC Certificates,
to the extent it relates to matters of law or legal conclusions with respect
thereto, represents the opinion of Orrick, Herrington & Sutcliffe LLP, special
counsel to Bank of America and Bank of America, FSB, subject to any
qualifications set forth herein. In addition, Orrick, Herrington & Sutcliffe
LLP, special counsel to Bank of America and Bank of America, FSB, have prepared
or reviewed the statements in this Prospectus under the heading "Certain Federal
Income Tax Consequences--REMIC Certificates," and are of the opinion that such
statements are correct in all material respects. Such statements are intended as
an explanatory discussion of the possible effects of
 
                                       47
<PAGE>
the classification of any Trust Fund as a REMIC for federal income tax purposes
on investors generally and of related tax matters affecting investors generally,
but do not purport to furnish information in the level of detail or with the
attention to an investor's specific tax circumstances that would be provided by
an investor's own tax advisor. Accordingly, each investor is advised to consult
its own tax advisors with regard to the tax consequences to it of investing in
REMIC Certificates.
 
    A.  TAX STATUS OF REMIC CERTIFICATES.  Unless otherwise specified in the
related Prospectus Supplement, the Certificates of any Series, in their
entirety, will generally be considered (i) "real estate assets" within the
meaning of Section 856(c)(4)(A) of the Code and (ii) assets described in Section
7701(a)(19)(C) of the Code (assets qualifying under one or more of those
sections, applying each section separately, "qualifying assets") for a calendar
quarter if at least 95% of the assets of the related Trust Fund are qualifying
assets during such calendar quarter. In the event the percentage of the Trust
Fund's assets which are qualifying assets falls below 95% for any calendar
quarter, then a corresponding percentage of the Certificates will be treated as
qualifying assets for such calendar quarter. Any amount includable in gross
income with respect to the Certificates will be treated as "interest on
obligations secured by mortgages on real property or on interests in real
property" within the meaning of Section 856(c)(3)(B) of the Code to the extent
that the Certificates are treated as "real estate assets" within the meaning of
Section 856(c)(4)(A) of the Code. The assets of the Trust Fund will include, in
addition to the Contracts, payments on the Contracts held pending distribution,
and may include, among other assets, one or more Reserve Funds. With respect to
the treatment of Contracts as qualifying assets, (i) the Treasury Regulations
under Section 856 of the Code define a "real estate asset" under Section
856(c)(5)(A) of the Code to include a loan secured by manufactured housing that
qualifies as a single family residence under the Code, and (ii) the Treasury
Regulations under Section 7701(a)(19)(C) of the Code provide that assets
described in that Section include loans secured by manufactured housing that
qualifies as a single family residence under the Code. It is unclear whether
other assets of the Trust Fund would be treated as qualifying assets under the
foregoing sections of the Code. REMIC Certificates held by a regulated
investment company will not constitute "Government Securities" within the
meaning of Code Section 851(b)(4)(A)(ii).
 
    B.  QUALIFICATION AS A REMIC.  Qualification as a REMIC requires ongoing
compliance with certain conditions. The following discussion assumes that such
requirements will be satisfied by a Trust Fund so long as any REMIC Certificates
related to such Trust Fund are outstanding. Substantially all of the assets of
the REMIC must consist of "qualified mortgages" and "permitted investments" as
of the close of the third month beginning after the day on which the REMIC
issues all of its regular and residual interests (the "Startup Day") and at all
times thereafter. The term "qualified mortgage" means any obligation (including
a participation or certificate of beneficial ownership in such obligation) which
is principally secured by an interest in real property that is transferred to
the REMIC on the Startup Day in exchange for regular or residual interests in
the REMIC or is purchased by the REMIC within the three-month period beginning
on the Startup Day if such purchase is pursuant to a fixed price contract in
effect on the Startup Day. The REMIC Regulations provide that a manufactured
housing contract is principally secured by an interest in real property if the
fair market value of the real property securing the contract is at least equal
to either (i) 80% of the issue price (generally, the principal balance) of the
contract at the time it was originated or (ii) 80% of the adjusted issue price
(the then outstanding principal balance, with certain adjustments) of the
contract at the time it is contributed to a REMIC. The fair market value of the
underlying real property is to be determined after taking into account other
liens encumbering that real property. Alternatively, a manufactured housing
contract is principally secured by an interest in real property if substantially
all of the proceeds of the contract were used to acquire or to improve or
protect an interest in real property that, at the origination date, is the only
security for the contract (other than the personal liability of the obligor).
The REMIC Regulations as well as a published notice issued by the Internal
Revenue Service (the "Service") provide that obligations secured by interests in
manufactured housing, which qualify as "single family residences" within the
meaning of Section 25(e)(10) of the Code, are to be treated as "qualified
mortgages" for qualifying a Trust Fund as a REMIC. Under Section 25(e)(10) of
the Code, the term "single family residence" includes any manufactured home
which has
 
                                       48
<PAGE>
a minimum of 400 square feet of living space and a minimum width in excess of
102 inches and which is of a kind customarily used at a fixed location. Bank of
America or Bank of America, FSB or both of them, as the case may be, will
represent and warrant that each of the manufactured homes securing the Contracts
conveyed by it to a Trust Fund meets this definition of a "single family
residence." A qualified mortgage also includes a "qualified replacement
mortgage" that is used to replace any "qualified mortgage" within three months
of the Startup Day or to replace a defective mortgage within two years of the
Startup Day.
 
    "Permitted investments" consist of (a) temporary investments of cash
received under qualified mortgages before distribution to holders of interests
in the REMIC ("cash-flow investments"), (b) amounts, such as a reserve fund, if
any, reasonably required to provide for full payment of expenses of the REMIC,
the principal and interest due on regular or residual interests in the event of
defaults on qualified mortgages, lower than expected returns on cash-flow
investments, prepayment interest shortfalls or certain other contingencies
("qualified reserve assets") and (c) certain property acquired as a result of
foreclosure of defaulted qualified mortgages ("foreclosure property"). A reserve
fund will not be qualified if more than 30% of the gross income from the assets
in the reserve fund is derived from the sale or other disposition of property
held for three months or less, unless such sale is necessary to prevent a
default in payment of principal or interest on Regular Certificates. In
accordance with Section 860G(a)(7) of the Code, a reserve fund must be "promptly
and appropriately" reduced as payments on contracts are received. Foreclosure
property will be a permitted investment only to the extent that such property is
not held for more than three years unless an extension of such holding period is
obtained from the Service.
 
    The Code requires that in order to qualify as a REMIC an entity must make
reasonable arrangements designed to ensure that certain specified entities,
generally including governmental entities or other entities that are exempt from
United States tax, including the tax on unrelated business income ("Disqualified
Organizations"), do not hold the residual interest in the REMIC. Consequently,
it is expected that in the case of any Trust Fund for which a REMIC election is
made, the transfer, sale, or other disposition of a Residual Certificate to a
Disqualified Organization will be prohibited, and the ability of a Residual
Certificate to be transferred will be conditioned on the Trustee's receipt of a
certificate or other document representing that the proposed transferee is not a
Disqualified Organization. The transferor of a Residual Certificate must not, as
of the time of the transfer, have actual knowledge that such representation is
false. The Code further requires that reasonable arrangements be made to enable
a REMIC to provide the Service and certain other parties, including transferors
of residual interests in a REMIC, with the information needed to compute the tax
imposed by Section 860E(e)(1) of the Code if, in spite of the steps taken to
prevent Disqualified Organizations from holding residual interests, such an
organization does, in fact, acquire a residual interest. See "Restrictions on
Transfer of Residual Certificates" below.
 
    For certain Series of Certificates, two or more separate elections may be
made to treat segregated portions of the assets of a single Trust Fund as REMICs
for federal income tax purposes. Upon the issuance of any such series of
Certificates, Orrick, Herrington & Sutcliffe LLP, special tax counsel to Bank of
America and Bank of America, FSB, will have advised Bank of America and Bank of
America, FSB, as described above, that at the initial issuance of the
Certificates of such Series, each such segregated portion qualify as a REMIC for
federal income tax purposes, and that the Certificates in such Series will be
treated either as Regular Certificates or Residual Certificates of the
appropriate REMIC. Solely for the purpose of determining whether such Regular
Certificates will constitute qualifying real estate or real property assets for
certain categories of financial institutions or real estate investment trusts as
described above under "--A. Tax Status of REMIC Certificates," some or all of
the REMICs in a multiple-tier REMIC structure may be treated as one. See the
discussion below under "--C. Taxation of Regular Certificates."
 
    If an entity electing to be treated as a REMIC fails to comply with one or
more of the ongoing requirements of the Code for REMIC status during any taxable
year, the Code provides that the entity will not be treated as a REMIC for such
year and thereafter. In this event, an entity with multiple classes of ownership
interests may be treated as a separate association taxable as a corporation
under Treasury regulations, and interests in the REMIC may be treated as debt or
equity interests therein. If the Trust
 
                                       49
<PAGE>
Fund were treated as a corporation, income of the Trust Fund would be subject to
corporate tax in the hands of the Trust Fund, and, therefore, only a reduced
amount might be available for distribution to Certificateholders. The Code
authorizes the Treasury Department to issue Treasury regulations that address
situations where failure to meet one or more of the requirements for REMIC
status occurs inadvertently and in good faith, and disqualification of a REMIC
would occur absent regulatory relief. Investors should be aware, however, that
the Conference Committee Report (the "Committee Report") to the Tax Reform Act
of 1986 (the "1986 Act") indicates that the relief may be accompanied by
sanctions, such as the imposition of a corporate income tax on all or a portion
of the REMIC's income for the period of time in which the requirements for REMIC
status are not satisfied. The Agreement with respect to each REMIC will include
provisions designed to maintain the related Trust Fund's status as a REMIC. It
is not anticipated that the status of any Trust Fund as a REMIC will be
terminated.
 
    C.  TAXATION OF REGULAR CERTIFICATES.
 
    1.  GENERAL.  The Regular Certificates in any Series will constitute
"regular interests" in the related REMIC. Accordingly, the Regular Certificates
will generally be treated for federal income tax purposes as debt instruments
that are issued by the related Trust Fund on the date of issuance of the Regular
Certificates and not as ownership interests in the Trust Fund or the Trust
Fund's assets. Interest, original issue discount, and market discount accrued on
a Regular Certificate will be treated as ordinary income to the holder. Each
holder must use the accrual method of accounting with regard to Regular
Certificates, regardless of the method of accounting otherwise used by such
holder. Payments of interest on REMIC Regular certificates may be based on a
fixed rate or a variable rate as permitted by the REMIC Regulations, or may
consist of a specified portion of the interest payments on qualified mortgages
where such portion does not vary during the period the REMIC Regular Certificate
is outstanding. If a Regular Certificate represents an interest in a REMIC that
consists of a specified portion of the interest payments on the REMIC's
qualified mortgages, the stated principal amount with respect to that Regular
Certificate may be zero.
 
    2.  ORIGINAL ISSUE DISCOUNT.  Certain Regular Certificates may be issued
with "original issue discount" within the meaning of Code Section 1273(a). Any
holders of Regular Certificates issued with original issue discount generally
will be required to include original issue discount in income as it accrues, in
accordance with a constant interest method that takes into account the
compounding of interest, in advance of the receipt of the cash attributable to
such income. The Company will report annually (or more often if required) to the
Internal Revenue Service ("IRS") and to Certificateholders such information with
respect to the original issue discount accruing on the REMIC Regular
Certificates as may be required under Code Section 6049 and the regulations
thereunder. See "--11. Reporting Requirements" below.
 
    Rules governing original issue discount are set forth in Code Sections 1271
through 1273 and 1275 and, to some extent, in the OID Regulations. Code Section
1272(a)(6) provides special original issue discount rules applicable to Regular
Certificates. Regulations have not yet been proposed or adopted under Section
1272(a)(6) of the Code. Further, application of the OID Regulations to the
Regular Certificates remains unclear in some respects because the OID
Regulations generally purport not to apply to instruments to which section
1272(a)(6) applies such as Regular Certificates, and separately because they
either do not address, or are subject to varying interpretations with regard to,
several relevant issues.
 
    Code Section 1272(a)(6) requires that a mortgage prepayment assumption
("Prepayment Assumption") be used in computing the accrual of original issue
discount on Regular Certificates and for certain other federal income tax
purposes. The Prepayment Assumption is to be determined in the manner prescribed
in Treasury regulations. To date, no such regulations have been promulgated. The
Committee Report indicates that the regulations will provide that the Prepayment
Assumption, if any, used with respect to a particular transaction must be the
same as that used by the parties in pricing the transaction. Unless otherwise
specified in the applicable Prospectus Supplement, the Company will use a
percentage of the prepayment assumption specified in the applicable Prospectus
Supplement in reporting original issue
 
                                       50
<PAGE>
discount that is consistent with this standard. However, the Company does not
make any representation that the Mortgage Loans will in fact prepay at a rate
equal to that prepayment assumption or at any other rate. Each investor must
make its own decision as to the appropriate prepayment assumption to be used in
deciding whether or not to purchase any of the Regular Certificates. The
Prospectus Supplement with respect to a Series of Certificates will disclose the
prepayment assumption to be used in reporting original issue discount, if any,
and for certain other federal income tax purposes.
 
    The total amount of original issue discount on a Regular Certificate is the
excess of the "stated redemption price at maturity" of the Regular Certificate
over its "issue price". Except as discussed in the following two paragraphs, in
general, the issue price of a particular Class of Regular Certificates offered
hereunder will be the price at which a substantial amount of Regular
Certificates of that Class are first sold to the public (excluding bond houses
and brokers).
 
    If a Regular Certificate is sold with accrued interest that relates to a
period prior to the issue date of such Regular Certificate, the amount paid for
the accrued interest will be treated instead as increasing the issue price of
the Regular Certificate. In addition, that portion of the first interest payment
in excess of interest accrued from the Closing Date to the first Distribution
Date will be treated for federal income tax reporting purposes as includible in
the stated redemption price at maturity of the Regular Certificate, and as
excludible from income when received as a payment of interest on the first
Distribution Date. The OID Regulations suggest that some or all of this
pre-issuance accrued interest "may" be treated as a separate asset (and hence
not includible in a Regular Certificate's issue price or stated redemption price
at maturity), whose cost is recovered entirely out of interest paid on the first
Distribution Date. It is unclear how such treatment would be elected under the
OID Regulations and whether an election could be made unilaterally by a
Certificateholder.
 
    The stated redemption price at maturity of a Regular Certificate is equal to
the total of all payments to be made on such Certificate other than "qualified
stated interest." Under the OID Regulations, "qualified stated interest" is
interest that is unconditionally payable at least annually during the entire
term of the Certificate at either (i) a single fixed rate that appropriately
takes into account the length of the interval between payments or (ii) the
current values of a single "qualified floating rate" or "objective rate" (each,
a "Single Variable Rate"). A "current value" is the value of a variable rate on
any day that is no earlier than three months prior to the first day on which
that value is in effect and no later than one year following that day. A
"qualified floating rate" is a rate whose variations can reasonably be expected
to measure contemporaneous variations in the cost of newly borrowed funds in the
currency in which the Certificate is denominated. Such a rate remains qualified
even though it is multiplied by a fixed, positive multiple not exceeding 1.35,
increased or decreased by a fixed rate, or both. Certain combinations of rates
constitute a single qualified floating rate, including (i) interest stated at a
fixed rate for an initial period of less than one year followed by a qualified
floating rate if the value of the floating rate at the closing date is intended
to approximate the fixed rate, and (ii) two or more qualified floating rates
that can be expected to have appropriately the same values throughout the term
of the Certificate. A combination of such rates is conclusively presumed to be a
single floating rate if the values of all rates on the closing date are within
0.25% of each other. A variable rate that is subject to an interest rate cap,
floor, "governor" or similar restriction on rate adjustment may be a qualified
floating rate only if such restriction is fixed throughout the term of the
instrument, or is not reasonably expected as of the closing date to cause the
yield on the debt instrument to differ significantly from the expected yield
absent the restriction. An "objective rate" is a rate (other than a qualified
floating rate) determined using a single formula fixed for the life of the
Certificate, which is based on (i) one or more qualified floating rates
(including a multiple or inverse of a qualified floating rate), (ii) one or more
rates each of which would be a qualified floating rate for a debt instrument
denominated in a foreign currency, (iii) the yield of changes in price of one or
more items of "actively traded" personal property, (iv) a combination of rates
described in (i), (ii) and (iii), or (v) a rate designated by the IRS. However,
a variable rate is not an objective rate if it is reasonably expected that the
average value of the rate during the first half of the Certificate's term will
differ significantly from the
 
                                       51
<PAGE>
average value of such rate during the final half of its term. A combination of
interest stated at a fixed rate for an initial period of less than one year
followed by an objective rate is treated as a single objective rate if the value
of the objective rate at the closing date is intended to approximate the fixed
rate; such a combination of rates is conclusively presumed to be to be a single
objective rate if the objective rate on the closing date does not differ from
the fixed rate by more than 0.25%. The qualified stated interest payable with
respect to certain variable rate debt instruments not bearing stated interest at
a Single Variable Rate generally is determined under the OID Regulations by
converting such instruments into fixed rate debt instruments. Instruments
qualifying for such treatment generally include those providing for stated
interest at (i) more than one qualified floating rates, or at (ii) a single
fixed rate and (a) one or more qualified floating rates or (b) a single
"qualified inverse floating rate" (each, a "Multiple Variable Rate"). A
qualified inverse floating rate is an objective rate equal to a fixed rate
reduced by a qualified floating rate, the variations in which can reasonably be
expected to inversely reflect contemporaneous variations in the cost of newly
borrowed funds (disregarding permissible rate caps, floors, governors and
similar restrictions such as are described above). Under these rules, some of
the payments of interest on a Certificate bearing a fixed rate of interest for
an initial period followed by a qualified floating rate of interest in
subsequent periods could be treated as included in the stated redemption price
at maturity if the initial fixed rate were to differ sufficiently from the rate
that would have been set using the formula applicable to subsequent periods. See
"Taxation of Regular Certificates--3. Variable Rate Certificates". Regular
Certificates offered hereby other than Certificates providing for variable rates
of interest or for the accretion of interest are not anticipated to have stated
interest other than "qualified stated interest", but if any such REMIC Regular
Certificates are so offered, appropriate disclosures will be made in the
Prospectus Supplement. Some or all of the payments on REMIC Regular Certificates
providing for the accretion of interest will be included in the stated
redemption price at maturity of such Certificates.
 
    Under a de minimis rule in the Code, as interpreted in the OID Regulations,
original issue discount on a Regular Certificate will be considered to be zero
if such original issue discount is less than 0.25% of the stated redemption
price at maturity of the Regular Certificate multiplied by the weighted average
life of the Regular Certificate. For this purpose, the weighted average life of
the Regular Certificate is computed as the sum of the amounts determined by
multiplying the amount of each payment under the instrument (other than a
payment of qualified stated interest) by a fraction, whose numerator is the
number of complete years from the issue date until such payment is made, and
whose denominator is the stated redemption price at maturity of such Regular
Certificate. The IRS may be anticipated to take the position that this rule
should be applied taking into account the prepayment assumption and the effect
of any anticipated investment income. Under the OID Regulation, Regular
Certificates bearing only qualified stated interest except for any "teaser"
rate, interest holiday or similar provision would be treated as subject to the
de minimis rule if the greater of the deferred or foregone interest or the other
original issue discount is less than such de minimis amount.
 
    The OID Regulations generally would treat de minimis original issue discount
as includible in income as each principal payment is made, based on the product
of the total amount of such de minimis original issue discount and a fraction,
whose numerator is the amount of such principal payment and whose denominator is
the stated principal amount of the Regular Certificate. The OID Regulations also
would permit a Certificateholder to elect to accrue de minimis original issue
discount into income currently based on a constant yield method. See "Taxation
of Regular Certificates--4. Market Discount" and "--5. Premium".
 
    Each holder of a Regular Certificate must include in gross income the sum of
the "daily portions" of original issue discount on its Regular Certificate for
each day during its taxable year on which it held such Regular Certificate. For
this purpose, in the case of an original holder of a Regular Certificate, the
daily portions of original issue discount will be determined as follows. A
calculation will first be made of the portion of the original issue discount
that accrued during each accrual period, that is, unless otherwise stated in the
applicable Prospectus Supplement, each period that begins or ends on a date that
corresponds
 
                                       52
<PAGE>
to a Distribution Date on the Regular Certificate and begins on the first day
following the immediately preceding accrual period (beginning on the Closing
Date in the case of the first such period). For any accrual period such portion
will equal the excess, if any, of (i) the sum of (A) the present value of all of
the distributions remaining to be made on the Regular Certificate, if any, as of
the end of the accrual period and (B) the distribution made on such Regular
Certificate during the accrual period of amounts included in the stated
redemption price at maturity, over (ii) the adjusted issue price of such Regular
Certificate at the beginning of the accrual period. The present value of the
remaining payments referred to in the preceding sentence will be calculated
based on (i) the yield to maturity of the Regular Certificate, calculated as of
the settlement date, giving effect to the Prepayment Assumption, (ii) events
(including actual prepayments) that have occurred prior to the end of the
accrual period, and (iii) the prepayment assumption. The adjusted issue price of
a Regular Certificate at the beginning of any accrual period will equal the
issue price of such Certificate, increased by the aggregate amount of original
issue discount with respect to such Regular Certificate that accrued in prior
accrual periods, and reduced by the amount of any distributions made on such
Regular Certificate in prior accrual periods of amounts included in the stated
redemption price at maturity. The original issue discount accruing during any
accrual period will be allocated ratably to each day during the period to
determine the daily portion of original issue discount for each day. With
respect to an accrual period between the settlement date and the first
Distribution Date on the Regular Certificate (notwithstanding that no
distribution is scheduled to be made on such date) that is shorter than a full
accrual period, the OID Regulations permit the daily portions of original issue
discount to be determined according to any reasonable method.
 
    A subsequent purchaser of a Regular Certificate that purchases such Regular
Certificate at a cost (not including payment for accrued qualified stated
interest) less than its remaining stated redemption price at maturity will also
be required to include in gross income, for each day on which it holds such
Regular Certificate, the daily portions of original issue discount with respect
to such Regular Certificate, but reduced, if such cost exceeds the "adjusted
issue price", by an amount equal to the product of (i) such daily portions and
(ii) a constant fraction, whose numerator is such excess and whose denominator
is the sum of the daily portions of original issue discount on such Regular
Certificate for all days on or after the day of purchase. The adjusted issue
price of a Regular Certificate on any given day is equal to the sum of the
adjusted issue price (or, in the case of the first accrual period, the issue
price) of the Regular Certificate at the beginning of the accrual period during
which such day occurs and the daily portions of original issue discount for all
days during such accrual period prior to such day, reduced by the aggregate
amount of distributions previously made other than distributions of qualified
stated interest.
 
    3.  VARIABLE RATE CERTIFICATES.  Purchasers of Regular Certificates bearing
a variable rate of interest should be aware that there is uncertainty concerning
the application of Section 1272(a)(6) of the Code and the OID Regulations to
such Certificates. In the absence of other authority, the Company intends to be
guided by the provisions of the OID Regulations governing variable rate debt
instruments in adapting the provisions of Section 1272(a)(6) of the Code to such
Certificates for the purpose of preparing reports furnished to
Certificateholders. The effect of the application of such provisions generally
will be to cause Certificateholders holding Certificates bearing interest at a
Single Variable Rate to take into account for each period an amount
corresponding approximately to the sum of (i) the qualified stated interest,
accruing on the outstanding face amount of the Regular Certificate as the stated
interest rate for that Certificate varies from time to time and (ii) the amount
of original issue discount that would have been attributable to that period on
the basis of a constant yield to maturity for a bond issued at the same time and
issue price as the Regular Certificate, having the same face amount and schedule
of payments of principal as such Certificate, subject to the same prepayment
assumption, and bearing interest at a fixed rate equal to the value of the
applicable qualified floating rate or qualified inverse floating rate in the
case of a Certificate providing for either such rate, or equal to the fixed rate
that reflects the reasonably expected yield on the Certificate in the case of a
Certificate providing for an objective rate other than an inverse floating rate,
in each case as of the issue date. Certificateholders holding Regular
Certificates bearing interest at a Multiple Variable Rate generally will take
into account interest and original issue
 
                                       53
<PAGE>
discount under a similar methodology, except that the amounts of qualified
stated interest and original issue discount attributable to such a Certificate
first will be determined for an equivalent fixed rate debt instrument, the
assumed fixed rates for which are (a) for each qualified floating rate, the
value of each such rate as of the closing date (with appropriate adjustment for
any differences in intervals between interest adjustment dates), (b) for a
qualified inverse floating rate, the value of the rate as of the closing date,
(c) for any other objective rate, the fixed rate that reflects the yield that is
reasonably expected for the Certificate, and (d) for an actual fixed rate, such
hypothetical fixed rate as would result under (a) or (b) if the actual fixed
rate were replaced by a hypothetical qualified floating rate or qualified
inverse floating rate such that the fair market value of the Certificate as of
the issue date would be approximately the same as that of an otherwise identical
debt instrument providing for the hypothetical variable rate rather than the
actual fixed rate. If the interest paid or accrued with respect to a Multiple
Variable Rate Certificate during an accrual period differs from the assumed
fixed interest rate, such difference will be an adjustment (to interest or
original issue discount, as applicable) to the Certificateholder's taxable
income for the taxable period or periods to which such difference relates.
Additionally, purchasers of such Certificates should be aware that the
provisions of the OID Regulations applicable to variable rate debt instruments
have been limited and may not apply to some Regular Certificates having variable
rates. If such a Certificate is not governed by the provisions of the OID
Regulations applicable to variable rate debt instruments, it may be subject to
provisions of proposed Treasury Regulations applicable to instruments having
contingent payments. The application of those provisions to instruments such as
variable rate Regular Certificates is subject to differing interpretations.
Prospective purchasers of variable rate Regular Certificates are advised to
consult their tax advisors concerning the tax treatment of such Certificates.
 
    4.  MARKET DISCOUNT.  A Certificateholder that purchases a Regular
Certificate at a market discount, that is, at a purchase price less than the
adjusted issue price (as defined under "--Taxation of Regular Certificates--2.
Original Issue Discount") of such Regular Certificate generally will recognize
market discount upon receipt of each distribution of principal. In particular,
such a holder will generally be required to allocate each payment of principal
on a Regular Certificate first to accrued market discount, and to recognize
ordinary income to the extent such principal payment does not exceed the
aggregate amount of accrued market discount on such Regular Certificate not
previously included in income. Such market discount must be included in income
in addition to any original issue discount includible in income with respect to
such Regular Certificate.
 
    A Certificateholder may elect to include market discount in income currently
as it accrues, rather than including it on a deferred basis in accordance with
the foregoing. If made, such election will apply to all market discount bonds
acquired by such Certificateholder on or after the first day of the first
taxable year to which such election applies. In addition, the OID Regulations
permit a Certificateholder to elect to accrue all interest, discount (including
de minimis market or original issue discount) and premium in income as interest,
based on a constant yield method. If such an election were made for a Regular
Certificate with market discount, the Certificateholder would be deemed to have
made an election to currently include market discount in income with respect to
all other debt instruments having market discount that such Certificateholder
acquires during the year of the election or thereafter. Similarly, a
Certificateholder that makes this election for a Certificate that is acquired at
a premium is deemed to have made an election to amortize bond premium, as
described below, with respect to all debt instruments having amortizable bond
premium that such Certificateholder owns or acquires. The election to accrue
interest, discount and premium on a constant yield method with respect to a
Certificate is irrevocable.
 
    Under a statutory de minimis exception, market discount with respect to a
Regular Certificate will be considered to be zero for purposes of Code Sections
1276 through 1278 if such market discount is less than 0.25% of the stated
redemption price at maturity of such Regular Certificate multiplied by the
number of complete years to maturity remaining after the date of its purchase.
In interpreting a similar de minimis rule with respect to original issue
discount on obligations payable in installments, the OID Regulations refer to
the weighted average maturity of obligations, and it is likely that the same
rule will be applied in
 
                                       54
<PAGE>
determining whether market discount is de minimis. It appears that de minimis
market discount on a Regular Certificate would be treated in a manner similar to
original issue discount of a de minimis amount. See "Taxation of Regular
Certificates--2. Original Issue Discount". Such treatment would result in
discount being included in income at a slower rate than discount would be
required to be included using the method described above. However, Treasury
regulations implementing the market discount de minimis exception have not been
issued in proposed or temporary form, and the precise treatment of de minimis
market discount on obligations payable in more than one installment therefore
remains uncertain.
 
    The 1986 Act grants authority to the Treasury Department to issue
regulations providing for the method for accruing market discount of more than a
de minimis amount on debt instruments, the principal of which is payable in more
than one installment. Until such time as regulations are issued by the Treasury
Department, certain rules described in the Committee Report will apply. Under
those rules, the holder of a bond purchased with more than de minimis market
discount may elect to accrue such market discount either on the basis of a
constant yield method or on the basis of the appropriate proportionate method
described below. Under the proportionate method for obligations issued with
original issue discount, the amount of market discount that accrues during a
period is equal to the product of (i) the total remaining market discount,
multiplied by (ii) a fraction, the numerator of which is the original issue
discount accruing during the period and the denominator of which is the total
remaining original issue discount at the beginning of the period. Under the
proportionate method for obligations issued without original issue discount, the
amount of market discount that accrues during a period is equal to the product
of (i) the total remaining market discount, multiplied by (ii) a fraction, the
numerator of which is the amount of stated interest paid during the accrual
period and the denominator of which is the total amount of stated interest
remaining to be paid at the beginning of the period. The Prepayment Assumption,
if any, used in calculating the accrual of original issue discount is to be used
in calculating the accrual of market discount under any of the above methods.
Because the regulations referred to in this paragraph have not been issued, it
is not possible to predict what effect such regulations might have on the tax
treatment of a Regular Certificate purchased at a discount in the secondary
market.
 
    Further, a purchaser generally will be required to treat a portion of any
gain on sale or exchange of a Regular Certificate as ordinary income to the
extent of the market discount accrued to the date of disposition under one of
the foregoing methods, less any accrued market discount previously reported as
ordinary income. Such purchaser also may be required to defer a portion of its
interest deductions for the taxable year attributable to any indebtedness
incurred or continued to purchase or carry such Regular Certificate. Any such
deferred interest expense is, in general, allowed as a deduction not later than
the year in which the related market discount income is recognized. If such
holder elects to include market discount in income currently as it accrues on
all market discount instruments acquired by such holder in that taxable year or
thereafter, the interest deferral rule described above will not apply.
 
    5.  PREMIUM.  A Regular Certificate purchased at a cost (not including
payment for accrued qualified stated interest) greater than its remaining stated
redemption price at maturity will be considered to be purchased at a premium.
The holder of such a Regular Certificate may elect to amortize such premium
under the constant yield method. The OID Regulations also permit
Certificateholders to elect to include all interest, discount and premium in
income based on a constant yield method, further treating the Certificateholder
as having made the election to amortize premium generally, as discussed above.
The Committee Report indicates a Congressional intent that the same rules that
will apply to accrual of market discount on installment obligations will also
apply in amortizing bond premium under Code Section 171 on installment
obligations such as the Regular Certificates.
 
    6.  EFFECTS OF DEFAULTS OR DELINQUENCIES.  Certain Series of Certificates
may contain one or more Classes of Subordinate Certificates. In the event there
are defaults or delinquencies on Contracts in the related Trust Fund, amounts
that would otherwise be distributed on the Subordinate Certificates may instead
be distributed on the Senior Certificates. Holders of Subordinate Certificates
nevertheless will be required to report interest income with respect to such
Certificates (including original issue discount) as
 
                                       55
<PAGE>
such income accrues without giving effect to delays or reductions in
distributions on such Subordinate Certificates attributable to defaults and
delinquencies on such Contracts, except to the extent that it can be established
that the undistributed amounts are not collectible. As a result, the amount of
income reported by a holder of a Subordinate Certificate in any period could
significantly exceed the amount of cash distributed to such holder in that
period. The holder will eventually be allowed a loss (or will be allowed to
report a lesser amount of income) to the extent that the aggregate amount of
distributions on the Subordinate Certificate is reduced as a result of defaults
or delinquencies on the related Contracts. However, the timing of such losses or
reductions in income is uncertain, and in some circumstances losses could be
capital losses that generally can be offset only with capital gains. Holders of
Subordinate Certificates should consult their own tax advisors on these points.
 
    7.  SALES OF CERTIFICATES.  If a Regular Certificate is sold or exchanged,
the seller will recognize gain or loss equal to the difference, if any, between
the amount realized (net of accrued interest) and its adjusted basis in such
Regular Certificate. A seller's adjusted basis generally will equal the cost of
such Regular Certificate to the seller, increased by any original issue discount
reported by such seller with respect to such Regular Certificate and reduced
(but not below zero) by distributions received by such seller (other than
payments of qualified stated interest) and by any amortized premium. Except as
described above "--4. Market Discount" and with respect to the next three
paragraphs, any such gain or loss will be capital gain or loss provided the
Regular Certificate is held as a capital asset. The Taxpayer Relief Act of 1997
(the "1997 Act") has changed the tax rates and holding periods applicable to
long-term capital gains of individuals. Because the tax rates and applicable
holding periods will vary depending upon a Certificateholder's individual
circumstances, investors should consult their own tax advisors concerning the
effect of these 1997 Act changes.
 
    Gain from the disposition of a Regular Certificate that might otherwise be
capital gain will be treated as ordinary income to the extent that such gain
does not exceed the excess, if any, of (i) the amount that would have been
includable in the seller's gross income had income accrued at a rate equal to
110% of "the applicable Federal rate" under Section 1274(d) of the Code
(generally, an average yield of United States Treasury obligations of different
ranges of maturities published monthly by the Service), determined as of the
date of purchase of such Regular Certificate, over (ii) the amount of income
actually includable in the gross income of the seller with respect to the
Regular Certificate.
 
    Regular Certificates will be "evidences of indebtedness" within the meaning
of Section 582(c)(1) of the Code, and accordingly, gain or loss recognized from
a sale of a Regular Certificate by a bank or thrift institution to which such
section applies would be ordinary income or loss.
 
    If Bank of America and Bank of America, FSB, or either of them, is
determined to have intended on the date of issue of the Regular Certificates to
call all or any portion of the Regular Certificates prior to their stated
maturity within the meaning of Section 1271(a)(2)(A) of the Code, any gain
realized upon a sale, exchange, retirement, or other disposition of a Regular
Certificate would be considered ordinary income to the extent it does not exceed
the unrecognized portion of the original issue discount, if any, with respect to
the Regular Certificate. The OID Regulations provide that the intention to call
rule will not be applied to mortgage-backed securities such as the Regular
Certificates. In addition, under the OID Regulations, a mandatory sinking fund
or call option is not evidence of an intention to call.
 
    8.  PASS-THROUGH OF EXPENSES OTHER THAN INTEREST.  If a Trust Fund for which
a REMIC election is made is considered a "single-class REMIC" (as defined
below), a portion of such Trust Fund's servicing, administrative and other
non-interest expenses will be allocated as a separate item to those Regular
Certificateholders that are "pass-through interest holders" (as defined below).
Such a holder would be required to add its allocable share, if any, of such
expenses to its gross income and to treat the same amount as an item of
investment expense. An individual would generally be allowed a deduction for
such an expense item for regular tax purposes only as a miscellaneous itemized
deduction subject to the limitation under Section 67 of the Code, and may not be
allowed any deduction for such item for purposes
 
                                       56
<PAGE>
of the alternative minimum tax. Section 67 of the Code allows deductions for
miscellaneous itemized deductions only to the extent that in the aggregate they
exceed 2% of an individual's adjusted gross income. The Revenue Reconciliation
Act of 1990 further limits the itemized deductions allowed to certain
individuals. If so specified in the related Prospectus Supplement, the
applicable Agreement will require each holder to give the Trust Fund written
notice immediately upon becoming a holder, if it is a pass-through interest
holder, or is holding a Regular Certificate on behalf of a pass-through interest
holder. The Trust Fund will report to each holder that has given the Trust Fund
such notice (and others if it is required) and to the Service, each such
holder's allocable share, if any, of the Trust Fund's noninterest expenses.
Generally, a "single-class REMIC" is defined as (i) a REMIC that would be
treated as an investment trust under Treasury regulations but for its
qualification as a REMIC or (ii) a REMIC that is substantially similar to an
investment trust but is structured with the principal purpose of avoiding the
allocation requirement imposed under Section 67 of the Code. The term
"pass-through interest holder" generally refers to individuals, entities taxed
as individuals and certain pass-through entities, but does not include real
estate investment trusts. Such investors should consult their own tax advisors
regarding consequences to them of the allocation of the Trust Fund's
non-interest expenses. In addition, the amount of itemized deductions otherwise
allowable for the taxable year of an individual whose adjusted gross income
exceeds certain thresholds will be reduced.
 
    9.  TAXATION OF CERTAIN FOREIGN INVESTORS.  For purposes of this discussion,
a "Foreign Holder" is a Certificateholder who holds a Regular Certificate and
who is not (i) a citizen or resident of the United States, (ii) a corporation or
partnership organized in or under the laws of the United States, a state (other
than any partnership that is treated as not a United States person under any
Applicable Treasury regulations) thereof or the District of Columbia or an
entity taxable as such for U.S. federal income tax purposes, (iii) an estate,
the income of which is included in gross income for United States tax purposes
regardless of its source, or (iv) a trust if a court within the United States is
able to exercise primary supervision over the administration of the trust and
one or more United States fiduciaries have the authority to control all
substantial decisions of the trust. Unless the interest on a Regular Certificate
is effectively connected with the conduct by the Foreign Holder of a trade or
business within the United States, the Foreign Holder is not subject to federal
income or withholding tax on interest (or original issue discount, if any) on a
Regular Certificate (subject to possible backup withholding of tax, discussed
below), provided the Foreign Holder is not a controlled foreign corporation
related to Bank of America or Bank of America, FSB and does not own actually or
constructively 10% or more of the voting stock of Bank of America or Bank of
America, FSB. To qualify for this tax exemption, the Foreign Holder will be
required to provide periodically a statement signed under penalties of perjury
certifying that the Foreign Holder meets the requirements for treatment as a
Foreign Holder and providing the Foreign Holder's name and address. The
statement, which may be made on a Form W-8 or substantially similar substitute
form, generally must be provided in the year a payment occurs or in either of
the two preceding years. The statement must be provided either directly or
through a clearing organization or financial institution. This exemption may not
apply to a Foreign Holder that owns directly or indirectly both Regular
Certificates and Residual Certificates. If for any reason the exemption does not
apply, interest paid to Foreign Holders will be subject to U.S. withholding tax
at the rate of 30% (or, if applicable, a reduced rate provided in a tax treaty).
If the interest on a Regular Certificate is effectively connected with the
conduct by a Foreign Holder of a trade or business within the United States,
then the Foreign Holder will be subject to tax at regular graduated rates.
Foreign Holders should consult their own advisors regarding the specific tax
consequences of their owning a Regular Certificate.
 
    Any gain recognized by a Foreign Holder upon a sale, retirement or other
taxable disposition of a Regular Certificate generally will not be subject to
United States federal income tax unless either (i) the Foreign Holder is a
non-resident alien individual who holds the Regular Certificate as a capital
asset and who is present in the United States for 183 days or more in the
taxable year of the disposition and either the gain is attributable to an office
or other fixed place of business maintained in the United States by the
 
                                       57
<PAGE>
individual or the individual has a "tax home" in the United States, or (ii) the
gain is effectively connected with the conduct by the Foreign Holder of a trade
or business within the United States.
 
    A Regular Certificate will not be included in the estate of a Foreign Holder
who does not own actually or constructively 10% or more of the voting stock of
Bank of America or Bank of America, FSB. Regular Certificateholders who are
non-U.S. Persons and persons related to such holders should not acquire any
Residual Certificates, and Residual Certificateholders and persons related to
Residual Certificateholders should not acquire any Regular Certificates without
consulting their tax advisors as to the possible adverse tax consequences of
doing so.
 
    10.  BACKUP WITHHOLDING.  Under certain circumstances, a REMIC
Certificateholder may be subject to "backup withholding" at a 31% rate. Backup
withholding may apply to a REMIC Certificateholder who is a United States person
if the holder, among other circumstances, fails to furnish his Social Security
number or other taxpayer identification number to the Trustee. Backup
withholding may apply, under certain circumstances, to a REMIC Certificateholder
who is a foreign person if the REMIC Certificateholder fails to provide the
Trustee or the REMIC Certificateholder's securities broker with the statement
necessary to establish the exemption from federal income and withholding tax on
interest on the REMIC Certificates. Backup withholding, however, does not apply
to payments on a Certificate made to certain exempt recipients, such as
corporations and tax-exempt organizations, and to certain foreign persons. Each
non-exempt Certificateholder will be required to provide, under penalty of
perjury, a certificate on IRS Form W-9 containing his or her name, address,
correct federal taxpayer identification number and a statement that he or she is
not subject to backup withholding. REMIC Certificateholders should consult their
tax advisors for additional information concerning the potential application of
backup withholding to payments received by them with respect to a Certificate.
 
    11.  REQUIREMENTS.  The Servicer will report annually to the Service, to
holders of record of the Regular Certificates that are not excepted from the
reporting requirements and, to the extent required by the Code, to other
interested parties, information with respect to the interest paid or accrued on
the Regular Certificates, original issue discount, if any, accruing on the
Regular Certificates and information necessary to compute the accrual of any
market discount or the amortization of any premium on the Regular Certificates.
 
    12.  NEW WITHHOLDING REGULATIONS.  The Treasury Department has issued new
regulations (the "New Regulations") which make certain modifications to the
withholding, backup withholding and information reporting rules described above.
The New Regulations attempt to unify certification requirements and modify
reliance standards. The New Regulations will generally be effective for payments
made after December 31, 1999, subject to certain transition rules. Prospective
investors are urged to consult their own tax advisors regarding the New
Regulations.
 
    D.  TAXATION OF RESIDUAL CERTIFICATES.  The discussion under this heading
applies only to a Series of Certificates with respect to which a REMIC election
is made and to Residual Certificates. Such Residual Certificates will be subject
to tax rules, described below, that differ from those that would apply if they
were treated for federal income tax purposes as direct ownership interests in
the related Trust Fund or as debt instruments issued by such Trust Fund.
 
    1.  Although a REMIC is a separate entity for federal income tax purposes, a
REMIC is not generally subject to federal income tax. Rather, the taxable income
of a REMIC is taken into account by the holders of REMIC residual interests.
 
    In general, each original holder of a Residual Certificate will report on
its federal income tax return, as ordinary income, its share of the "daily
portion" of the taxable income of the Trust Fund for each day during the taxable
year on which such Residual Certificateholder held a Residual Certificate. The
"daily portion" of the taxable income of the Trust Fund is determined by
allocating to each day in any calendar quarter its ratable portion of the
taxable income or net loss of the Trust Fund for such quarter, and such
 
                                       58
<PAGE>
Residual Certificateholder's share of the "daily portion" is based on the
portion of outstanding Residual Certificates that such Residual
Certificateholder owns on such day. REMIC taxable income will be taxable to the
Residual Certificateholders without regard to the timing or amounts of cash
distributions by the REMIC. Ordinary income derived from Residual Certificates
will be "portfolio income" for purposes of the taxation of taxpayers subject to
the limitation on the deductibility of "passive losses." As residual interests,
the Residual Certificates will be subject to tax rules, described below, that
differ from those that would apply if the Residual Certificates were treated for
federal income tax purposes as direct ownership interests in the Contracts, or
as debt instruments issued by the REMIC. Under certain circumstances, a Residual
Certificateholder may be required to recognize for a given period income
substantially in excess of distributions made on the Residual Certificates.
 
    A subsequent Residual Certificateholder also will report on its federal
income tax return amounts representing a daily share of the taxable income of
the Trust Fund for each day that such Residual Certificateholder held such
Residual Certificate. Those daily amounts generally would equal the amounts,
described above, that would have been reported for the same days by a holder of
a Residual Certificate (an "Original Holder") that purchased such Residual
Certificate at its original issuance and held it continuously thereafter. As
discussed below, the taxable income of the Trust Fund will be calculated based
in part on the initial tax basis to the Trust Fund of its assets, which in turn
equals the sum of the issue prices of the Residual Certificates and each Class
of Regular Certificates. The legislative history of the 1986 Act indicates that
certain adjustments may be appropriate to reduce (or increase) the income of a
subsequent Residual Certificateholder that purchased such Residual Certificate
at a price greater than (or less than) the adjusted basis (as defined below in
"Distributions") such Residual Certificate would have in the hands of an
Original Holder. For the present, however, adjustments are apparently not
permitted or required.
 
    2.  A holder's adjusted basis in a Residual Certificate will equal the
purchase price of such Residual Certificate, increased by the amount of the
related Trust Fund's taxable income that is allocated to the holder of such
Residual Certificate, and decreased (but not below zero) by the amount of
distributions received thereon by such holder and the Trust Fund's net losses
allocated to such holder. Payments on a Residual Certificate (whether at their
scheduled times or as a result of prepayments) will generally not result in any
taxable income or loss to the holder of a Residual Certificate. If the amount of
such payment exceeds a holder's adjusted basis in its Residual Certificate,
however, the holder will recognize gain (treated as gain from the sale or
exchange of its Residual Certificate) to the extent of such excess. See "--10.
Sale or Exchange" below.
 
    3.  Taxable Income of the Trust Fund.  REMIC taxable income is generally
determined in the same manner as the taxable income of an individual using the
accrual method of accounting, except that (i) the limitation on deductibility of
investment interest expense and expenses for the production of income do not
apply, (ii) all bad loans will be deductible as business bad debts, and (iii)
the limitation on the deductibility of interest and expenses related to
tax-exempt income will apply. In general, the Trust Fund's taxable income will
reflect a netting of (i) the gross income produced by the assets of the Trust
Fund, including the stated interest and any original issue discount or market
discount income on the Contracts in the related Contract Pool (net of any
amortized premium on such Contracts), income from the investment or reinvestment
of cash flows and, if applicable, reserve assets, and amortization of any issue
premium with respect to the Regular Certificates and (ii) deductions, including
stated interest and original issue discount expense on Regular Certificates that
would be permitted if the Regular Certificates were indebtedness of the Trust
Fund, servicing fees, and other administrative expenses of the Trust Fund
(except as described below under "--5. Expenses Other Than Interest"). Any gain
or loss realized by the Trust Fund from the disposition of any asset is treated
as gain or loss from the sale or exchange of property that is not a capital
asset. If there is more than one Class of Regular Certificates, deductions
allowed to the Trust Fund with respect to the Regular Certificates will
generally be calculated separately with respect to each Class based on the yield
of that Class.
 
                                       59
<PAGE>
    For purposes of determining its taxable income, the Trust Fund will have an
initial aggregate tax basis in its assets equal to the sum of the issue prices
of the Regular Certificates and the Residual Certificates. The issue price of a
Certificate of a Class (whether Regular Certificates or Residual Certificates)
that is publicly offered will be the initial offering price to the public
(excluding bond houses and brokers) at which a substantial amount of the
Certificates of that Class is sold, and if not publicly offered will be the
price paid by the first buyer of a Certificate of such class. If a Residual
Certificate has a negative value, it is not clear whether its issue price would
be considered to be zero or such negative amount for purposes of determining the
REMIC's basis in its assets. The REMIC Regulations imply that residual interest
cannot have a negative basis or a negative issue price. However, the preamble to
the REMIC Regulations indicates that, while existing tax rules do not
accommodate such concepts, the Service is considering the tax treatment of these
types of residual interests, including the proper tax treatment of a payment
made by the transferor of such a residual interest to induce the transferee to
acquire that interest. Absent regulations or administrative guidance to the
contrary, and unless the related Prospectus Supplement otherwise provides, it is
not expected that any Trust Fund as to which a REMIC election is made will treat
a Class of Residual Certificates as having a value of less than zero for
purposes of determining the basis of the related REMIC in its assets. If a Trust
Fund acquires a Contract and the principal amount of such Contract (or revised
issue price in the case of a Contract issued with original issue discount)
exceeds the Trust Fund's basis in such Contract by more than a de minimis amount
(as described above in "C. Taxation of Regular Certificates--5. Market
Discount"), such discount would generally be includable in the Trust Fund's
income as it accrues, in advance of receipt of the cash attributable to such
income, under a constant yield method, similar to the method for accruing
original issue discount on Regular Certificates described above in "C. Taxation
of Regular Certificates--2. Original Issue Discount." The Trust Fund's
deductions for original issue discount expense with respect to Regular
Certificates also will be determined under those rules, except that the de
minimis rule that may apply to holders of Regular Certificates and the
adjustments for holders of Regular Certificates that purchase their Certificates
at a price greater than the adjusted issue price described therein will not
apply.
 
    If the Trust Fund's basis in a Contract exceeds the remaining stated
redemption price at maturity of such a Contract, the Trust Fund will be
considered to have acquired such Contract at a premium equal to the amount of
such excess. In the event that any Contract in the Contract Pool is acquired by
the Trust Fund at a premium, the Trust Fund will be entitled to amortize such
premium on a yield-to-maturity basis. Although the matter is not free from
doubt, the Trust Fund intends to make this calculation using a reasonable
prepayment assumption.
 
    If a Class of Regular Certificates is issued at a price in excess of the
aggregate principal amount of such Class (the excess, the "Issue Premium"), the
portion of the Issue Premium that is considered to be amortized during a taxable
year will be treated as ordinary income of the Trust Fund for such taxable year.
Although the matter is not entirely certain, it is likely that the Issue Premium
would be amortized under a constant yield method in a manner analogous to the
method of accruing original issue discount described above under "C. Taxation of
Regular Certificates--2. Original Issue Discount."
 
    The taxable income recognized by a holder of a Residual Certificate in any
taxable year will be affected by, among other factors, the relationship between
the timing of interest, original issue discount or market discount income, or
amortization of premium with respect to the Contracts, on the one hand, and the
timing of deductions for interest (including original issue discount) on the
Regular Certificates, on the other hand. In the event that an interest in the
Contracts is acquired by a REMIC at a discount, and one or more of such
Contracts is prepaid, a holder of a Residual Certificate may recognize taxable
income without being entitled to receive a corresponding cash distribution
because (i) the prepayment may be used in whole or in part to make distributions
on Regular Certificates, and (ii) the discount on the Contracts which is
included in a REMIC's income may exceed its deduction with respect to the
distributions on those Regular Certificates. When there is more than one class
of Regular Certificates that receive payments sequentially (i.e., a fast-pay,
slow-pay structure), this mismatching of income and deductions is particularly
 
                                       60
<PAGE>
likely to occur in the early years following issuance of the Regular
Certificates, when distributions are being made in respect of earlier classes of
Regular Certificates to the extent that such classes are not issued with
substantial discount. If taxable income attributable to such a mismatching is
realized, in general, losses would be allowed in later years as distributions on
the later classes of Regular Certificates are made. The taxable income
recognized by a holder of a Residual Certificate also may be greater in earlier
years because the REMIC will use a constant yield in computing income from the
Contracts, while interest deductions with respect to Regular Certificates,
expressed as a percentage of the outstanding principal amount of the Regular
Certificates, may increase over time as earlier, lower-yielding Classes are
paid. The mismatching of income and deductions described in this paragraph, if
present with respect to a series of Residual Certificates, could have a
significant adverse effect upon the holder's after-tax rate of return. In
addition, a holder of a Residual Certificate may need to have sufficient other
sources of cash to pay any federal, state, or local income taxes due as a result
of such mismatching, or such holders must have unrelated deductions against
which to offset such income, subject to the discussion of "excess inclusions"
below in "--7. Excess Inclusions."
 
    A Residual Certificateholder will not be permitted to amortize the cost of
its Residual Certificate as an offset to its share of the taxable income of the
Trust Fund. However, that taxable income will not include cash received by the
Trust Fund that represents a recovery of the Trust Fund's basis in its assets
(which will include the issue price of the Residual Certificates as well as the
issue price of Regular Certificates). Such recovery of basis by the Trust Fund
will have the effect of amortization of the issue price of the Residual
Certificates over the life of the Trust Fund's assets. However, in view of the
possible acceleration of the income of holders of Residual Certificates
described above, the period of time over which such issue price is effectively
amortized may be longer than the economic life of the Residual Certificates.
 
    The method of taxation of Residual Certificates described above can produce
a significantly lower after-tax yield for a Residual Certificate than would be
the case if (i) Residual Certificates were taxable in the same manner as debt
instruments issued by the Trust Fund or (ii) no portion of the taxable income on
the Residual Certificates in each period were treated as "excess inclusions" (as
defined below). In certain periods, taxable income and the resulting tax
liability on a Residual Certificate are likely to exceed payments received
thereon. In addition, a substantial tax may be imposed on certain transferors of
the Residual Certificates and certain beneficial owners of the Residual
Certificates that are "pass-through" entities. Investors should consult their
tax advisors before purchasing a Residual Certificate.
 
    4.  NET LOSSES OF THE TRUST FUND.  The Trust Fund will have a net loss for a
calendar quarter if its deductions for that calendar quarter exceed its gross
income for that calendar quarter. The net loss allocable to any Residual
Certificate will not be deductible by the holder to the extent that such net
loss exceeds such holder's adjusted basis (as defined above in "--2.
Distributions") in such Residual Certificate at the end of the calendar quarter
in which such loss arises (or the time of disposition of the Residual
Certificate, if earlier), determined without taking into account the net loss
for such quarter. Any net loss that is not currently deductible by reason of
this limitation may be carried forward indefinitely, but may be used only to
offset taxable income of the same Trust Fund subsequently allocated to such
Residual Certificateholder. The ability of Residual Certificateholders that are
individuals or closely-held corporations to deduct net losses may be subject to
additional limitations under the Code.
 
    5.  EXPENSES OTHER THAN INTEREST.  Except in the limited circumstance when
the Trust Fund is considered a "single-class REMIC" (as defined above in "C.
Taxation of Regular Certificates--8. Pass-Through of Expenses Other Than
Interest"), the Trust Fund's servicing, administrative and other noninterest
expenses will be allocated entirely to the Residual Certificateholders. In the
case where the Trust Fund is considered a single-class REMIC, such expenses will
be allocated proportionately among Regular and Residual Certificateholders. See
"C. Taxation of Regular Certificates--8. Pass-Through of Expenses Other Than
Interest." In either case, such expenses will be allocated as a separate item to
those holders that are "pass-through interest holders" (as defined above in "C.
Taxation of Regular Certificates--8. Pass-Through
 
                                       61
<PAGE>
of Expenses Other Than Interest"). Such a holder would be required to add its
allocable share, if any, of such expenses to its gross income and treat the same
amount as an item of investment expense. Limitations on the deductibility of
such expenses are described above in "C. Taxation of Regular Certificates--8.
Pass-Through of Expenses Other Than Interest." The related Agreement will
require each holder to give the Trust Fund written notice upon becoming a holder
if it is a pass-through interest holder, or is holding a Residual Certificate on
behalf of a pass-through interest holder. The Trust Fund will report quarterly
to each holder of a Residual Certificate during any calendar quarter that has
given the Trust Fund such notice (and others if it is required) and to the
Service annually such holder's allocable share, if any, of the Trust Fund's
non-interest expenses. Such investors should consult their tax advisors in
determining the consequences to them of the allocation of the Trust Fund's
non-interest expenses.
 
    6.  TRANSACTIONS; SPECIAL TAXES.  Income from certain transactions by the
REMIC, called prohibited transactions, will not be part of the calculation of
income or loss includable in the federal income tax returns of Residual
Certificateholders, but rather will be taxed directly to the REMIC at a 100%
rate. Prohibited transactions generally include (i) the disposition of qualified
mortgages other than pursuant to a (a) substitution for a defective mortgage
within two years or for any qualified mortgage within three months of the
specified Startup Date, (b) repurchase of a defective mortgage, (c) foreclosure,
default, or imminent default of a qualified mortgage, (d) bankruptcy or
insolvency of the REMIC or (e) a qualified (complete) liquidation of the REMIC,
(ii) the receipt of income from assets that are not the type of mortgage loans
or investments that the REMIC is permitted to hold, (iii) the receipt of
compensation for services or (iv) the receipt of gain from disposition of cash
flow investments other than pursuant to a qualified (complete) liquidation of
the REMIC. The Trust Fund will be subject to a tax equal to 100% of the amount
of any contributions of property made to the Trust Fund after the Startup Day,
except for certain cash contributions specified in Section 860G(d) of the Code.
An additional tax may be imposed on the Trust Fund, at the highest marginal
federal corporate income tax rate, on certain net income from foreclosure
property.
 
    It is anticipated that the Trust Fund will not engage in any prohibited
transactions in which it would recognize a material amount of net income or
receive substantial contributions of property after the Startup Date. However,
if the Trust Fund is subject to the tax on prohibited transactions or
contributions, such tax would generally be borne by the Residual
Certificateholders.
 
    7.  EXCESS INCLUSIONS.  A portion of the income of the Trust Fund allocable
to a Residual Certificateholder referred to in the Code as an "excess inclusion"
will be subject to federal income tax in all events. (Excess inclusions are
defined below.) Thus, for example, an excess inclusion (i) may not be offset by
any unrelated losses or net operating loss carryovers of a Residual
Certificateholder, (ii) will be treated as "unrelated business taxable income"
within the meaning of Section 512 of the Code if the Residual Certificateholder
is a pension fund or any other organization that is subject to tax only on its
unrelated business taxable income and (iii) is not eligible for any reduction in
the rate of withholding tax in the case of a Residual Certificateholder that is
a foreign investor, as further discussed in "--13. Foreign Investors" below. In
addition, if a real estate investment trust, regulated investment company, or
certain pass-through entities own a Residual Certificate, a portion of dividends
paid by such entities would be treated as excess inclusions in the hands of its
shareholders with the same consequences as excess inclusions attributed directly
to a Residual Certificateholder.
 
    Except as discussed in the following paragraph, with respect to any Residual
Certificateholder, the excess inclusion for any calendar quarter will equal the
excess, if any, of (i) the amount of the Trust Fund's taxable income for the
calendar quarter allocable to the Residual Certificateholder, over (ii) the sum
of the "daily accruals" (as defined below) for all days during the calendar
quarter on which the Residual Certificateholder held such Residual Certificate.
For this purpose, daily accruals with respect to a Residual Certificateholder
will be calculated by allocating to each day in such calendar quarter its
ratable portion of the product of (i) the "adjusted issue price" (as defined
below) of the Residual Certificate at the beginning of such calendar quarter,
and (ii) 120% of the "long-term Federal rate" (defined below), calculated on the
 
                                       62
<PAGE>
issue date of the Residual Certificate as if it were a debt instrument and based
on quarterly compounding. For this purpose, the "adjusted issue price" of a
Residual Certificate at the beginning of any calendar quarter will equal its
issue price, increased by the aggregate of the daily accruals for all prior
calendar quarters and the amount of any contributions made to the Trust Fund
with respect to the Residual Certificates after the Startup Date, and decreased
(but not below zero) by the aggregate amount of distributions made with respect
to the Residual Certificate before the beginning of such calendar quarter. The
"long-term Federal rate" is an average of current yields on Treasury securities
with a remaining term of greater than nine years, computed and published monthly
by the Service. As an exception to the general rule described above, the
Treasury has authority to issue regulations that would treat 100% of the income
accruing on a Residual Certificate as an excess inclusion, if the Residual
Certificates, in the aggregate, are considered not to have "significant value."
The REMIC Regulations, however, do not contain such a rule.
 
    The Small Business Act has eliminated a special rule that formerly permitted
certain financial institutions utilizing the reserve method of accounting for
bad debts pursuant to Section 593 of the Code to use net operating losses and
other allowable deductions to offset their excess inclusions from certain REMIC
residual certificates. In addition, the Small Business Act provides three rules
for determining the effect of excess inclusions on the alternative minimum
taxable income of a holder of a REMIC residual certificate. First, alternative
minimum taxable income for such a residual holder is determined without regard
to the special rule that taxable income cannot be less than excess inclusions.
Second, a residual holder's alternative minimum taxable income for a tax year
cannot be less than the excess inclusions for the year. Third, the amount of any
alternative minimum tax net operating loss deductions must be computed without
regard to any excess inclusions.
 
    8.  EFFECT OF DEFAULTS AND DELINQUENCIES.  The Residual Certificates of a
multiple-Class Series may be subordinate to one or more Classes of Regular
Certificates (for purposes of this paragraph, "Senior Certificates"), and, in
the event there are defaults or delinquencies on the Contracts in the related
Contract Pool, amounts that would otherwise be distributed on the Residual
Certificates may instead be distributed on the Senior Certificates. However, the
Trust Fund will generally be required to report income in respect of Contracts
(and deductions with respect to the Regular Certificates) without giving effect
to default and delinquencies, except to the extent it can be established that
amounts due on the Contracts are uncollectible. To the extent the income on a
delinquent or defaulted Contract is greater than the deduction allowed in
respect of interest on the Regular Certificate that relates to such Contract,
the Trust Fund may recognize net income without making corresponding
distributions of cash on the Residual Certificates, and holders of Residual
Certificates will be required to report their pro rata share of the net income
of the Trust Fund without regard to the timing and amount of cash distributed on
such Residual Certificates.
 
    9.  TAX ON TRANSFERS OF RESIDUAL CERTIFICATES TO CERTAIN ORGANIZATIONS.  An
entity will not qualify as a REMIC unless there are reasonable arrangements
designed to ensure that residual interests in such entity are not held by
"disqualified organizations" (as defined below). Restrictions on the transfer of
the Residual Certificates that are intended to meet this requirement will be
included in the related Agreement and are discussed more fully in "Restrictions
on Transfer of REMIC Residual Certificates." If, notwithstanding those
restrictions, a Residual Certificate is transferred to a "disqualified
organization," a tax would be imposed in an amount equal to the product of (i)
the present value of the total anticipated excess inclusions with respect to
such Residual Certificate for periods after the transfer and (ii) the highest
marginal federal income tax rate applicable to corporations. Under the REMIC
Regulations, the anticipated excess inclusions must be determined based on (i)
events that have occurred up to the time of the transfer and (ii) the project
payments based on the Assumed Prepayment Rate. The REMIC Regulations also
provide that the present value of the anticipated excess inclusions is
determined by discounting the anticipated excess inclusions as of the date of
the transfer using the applicable Federal rate under Section 1274(d)(1) of the
Code for the month of the transfer that would apply to a hypothetical obligation
with a term beginning on the date of the transfer and ending on the date the
life of the REMIC is anticipated to expire (as determined under rules described
above in "--7. Excess Inclusions"). Such a tax
 
                                       63
<PAGE>
would generally be imposed on the transferor of the Residual Certificate, except
that where such transfer is through an agent for a disqualified organization,
the tax would instead be imposed on such agent. However, a transferor of a
Residual Certificate (or an agent for a disqualified organization) would in no
event be liable for such tax with respect to a transfer if the transferee
furnishes to such transferor (or such agent) an affidavit that the transferee is
not a disqualified organization, and as of the time of the transfer the
transferor or the agent does not have actual knowledge that such affidavit is
false.
 
    In addition, if a "pass-through entity" (as defined below) includes in
income excess inclusions with respect to a Residual Certificate, and a
disqualified organization is the record holder of an interest in such entity,
then a tax will be imposed on such entity equal to the product of (i) the amount
of excess inclusions on the Residual Certificate that are allocable to the
interest in the pass-through entity held by such disqualified organization and
(ii) the highest marginal federal income tax rate imposed on corporations.
However, a pass-through entity will in no event be liable for such tax with
respect to a record holder if the record holder furnishes the pass-through
entity with an affidavit that the record holder is not a disqualified
organization, and, as of the time the record holder becomes such a holder, the
pass-through entity does not have actual knowledge that such affidavit is false.
 
    For these purposes, the term "disqualified organization" means (i) the
United States, any State or political subdivision thereof, any possession of the
United States, any foreign government, any international organization, or any
agency or instrumentality of the foregoing (other than an instrumentality that
is a corporation if all of its activities are subject to tax and, except for the
Federal Home Loan Mortgage Corporation, a majority of its board of directors is
not selected by an such governmental unit), (ii) an organization (other than a
cooperative described in Section 521 of the Code) which is exempt from federal
income tax (including the tax imposed by Section 511 of the Code on unrelated
business taxable income) on excess inclusions or (iii) any organization
described in Section 1381(a)(2)(C) of the Code. For these purposes, the term
"pass-through entity" means any regulated investment company, real estate
investment trust, common trust fund, partnership, trust, estate and certain
other entities described in Section 860E(e)(6) of the Code. Except as may be
provided in Treasury Regulations, any person holding an interest in a
pass-through entity as a nominee for another will, with respect to such
interest, be treated as a pass-through entity.
 
    10.  SALE OR EXCHANGE.  If a Residual Certificate is sold or exchanged, the
seller will recognize gain or loss equal to the difference, if any, between the
amount realized and its adjusted basis in the Residual Certificate (as defined
above in "--2. Distributions") at the time of such sale or exchange (except that
the recognition of a loss may be limited under the "wash sale" rules described
below). In general, any such gain or loss will be capital gain or loss, provided
the Residual Certificate is held as a capital asset as defined in Section 1221
of the Code. However, a Residual Certificate will be an "evidence of
indebtedness" within the meaning of Section 582(c)(1) of the Code, so that gain
or loss recognized from the sale of a Residual Certificate by a bank or thrift
institution to which such section applies would be ordinary income or loss.
 
    Section 860F(d) of the Code and the Conference Committee Report to the 1986
Act indicate that, except as provided in Treasury Regulations, the wash sale
rules of Section 1091 of the Code will apply to dispositions of Residual
Certificates where the seller of the Residual Certificate, during the period
beginning six months before the sale or disposition of the Residual Certificate
and ending six months after such sale or disposition, acquires (or enters into
any other transaction that results in the application of Section 1091 of the
Code) any residual interest in any REMIC or any interest in a "taxable mortgage
pool" (such as a non-REMIC owner trust) that is economically comparable to a
Residual Certificate.
 
    11.  NONECONOMIC RESIDUAL INTERESTS.  Under the REMIC Regulations, a
transfer of a "noneconomic residual interest" (as defined below) to a Residual
Holder (other than a Foreign Holder, as discussed below) is disregarded for all
federal income tax purposes if a significant purpose of the transfer is to
enable the transferor to impede the assessment or collection of tax. If a
transfer of a residual interest is disregarded, the transferor would continue to
be treated as the owner of the residual interest and thus
 
                                       64
<PAGE>
would continue to be subject to tax on its allocable portion of the net income
of the REMIC. A residual interest in a REMIC (including a residual interest with
a positive value at issuance) is a "noneconomic residual interest" unless, at
the time of transfer (i) the present value of the expected future distributions
on the residual interest at least equals the product of the present value of the
anticipated excess inclusions and the highest corporate income tax rate in
effect for the year in which the transfer occurs and (ii) the transferor
reasonably expects that the transferee will receive distributions from the REMIC
at or after the time at which taxes accrue on the anticipated excess inclusions
in an amount sufficient to satisfy the accrued taxes. The anticipated excess
inclusions and the present value rate are determined in the same manner as set
forth above. The REMIC Regulations explain that a significant purpose to impede
the assessment or collection of tax exists if the transferor at the time of the
transfer either knew or should have known that the transferee would be unwilling
or unable to pay taxes due on its share of the taxable income of the REMIC. A
safe harbor is provided if (i) the transferor conducted, at the time of the
transfer, a reasonable investigation of the financial condition of the
transferee and, as a result of the investigation, the transferor found that the
transferee had historically paid its debts as they came due and found no
significant evidence to indicate that the transferee will not continue to pay
its debts as they come due in the future and (ii) the transferee represents to
the transferor that it understands that, as the holder of a non-economic
residual interest, the transferee may incur tax liabilities in excess of any
cash flows generated by the interest and that the transferee intends to pay
taxes associated with holding the residual interest as they become due. The
Agreement with respect to each Series of REMIC Certificates will require the
transferee of a Residual Certificate to certify to the statements in clause (ii)
of the preceding sentence as part of the affidavit described below under
"Restrictions on Transfer of REMIC Residual Certificates."
 
    12.  TERMINATION.  The Trust Fund related to a Series of Certificates will
terminate shortly following the retirement of Certificates in such Series. If a
Residual Certificateholder's adjusted basis in its Residual Certificate exceeds
the amount of cash distributed to such Residual Certificateholder in final
liquidation of its interest, then, although the matter is not entirely free from
doubt, it would appear that the Residual Certificateholder is entitled to a loss
equal to the amount of such excess.
 
    13.  FOREIGN INVESTORS.  Unless otherwise provided in the applicable
Prospectus Supplement, no record or beneficial ownership interest in a Residual
Certificate may be transferred to a Foreign Holder. See "Restrictions on
Transfer of REMIC Residual Certificates" below. With respect to permitted
transfers to Foreign Holders, any such Residual Certificateholders should assume
that payments made on the Residual Certificates they hold will be subject to a
30% withholding tax, or such a lesser rate as may be provided under any
applicable tax treaty, except that the rate of withholding on any payments made
on Residual Certificates that are excess inclusions will not be eligible for
reduction under any applicable tax treaties. See "--7. Excess Inclusions" above.
Under the REMIC Regulations, a transfer of a residual interest that has tax
avoidance potential is disregarded for all federal income tax purposes if the
transferee is a Foreign Holder. The REMIC Regulations state that a residual
interest has tax avoidance potential unless, at the time of the transfer, the
transferor reasonably expects that, for each excess inclusion, the REMIC will
distribute to the transferee residual interest holder an amount that will equal
at least 30% of the excess inclusion, and that each such amount will be
distributed at or after the time at which the excess inclusion accrues and not
later than the close of the calendar year following the calendar year of
accrual. See "--9. Tax on Transfers of Residual Certificates to Certain
Organizations" above for rules regarding the determination of anticipated excess
inclusions. The above rules do not apply to transfers of Residual Certificates
if the transferee's income from the Residual Certificate would be effectively
connected with a United States trade or business of the transferee. The REMIC
Regulations also provide that a transfer of a Residual Certificate from a
Foreign Holder to a United States person or to a Foreign Holder in whose hands
the income from the Residual Certificate would be effectively connected with a
United States trade or business of the transferee will be disregarded if the
transfer has the effect of allowing the transferor to avoid tax on accrued
excess inclusions.
 
                                       65
<PAGE>
    14.  MARK-TO-MARKET RULES.  Treasury regulations provided that a Residual
Certificate acquired after January 3, 1995 will not be treated as a security and
therefore generally cannot be marked to market.
 
    15.  ADDITIONAL TAXABLE INCOME OF RESIDUAL INTERESTS.  Any payment received
by a holder of a Residual Certificate in connection with the acquisition of such
Residual Certificate will be taken into account in determining the income of
such holder for federal income tax purposes. Although it appears likely that any
such payment would be includable in income immediately upon its receipt or
accrual as ordinary income, the IRS might assert that such payment should be
included in income over time according to an amortization schedule or according
to some other method. Because of the uncertainty concerning the treatment of
such payments, holders of Residual Certificates should consult their tax
advisors concerning the treatment of such payments for income tax purposes.
 
    E.  OTHER MATTERS RELATING TO REMIC CERTIFICATES; ADMINISTRATIVE
MATTERS.  Solely for the purposes of the administrative provisions of the Code,
each Trust Fund for which a REMIC election is made will be treated as a
partnership, and the Residual Certificateholders will be treated as the partners
thereof. The Trust Fund must maintain its books on a calendar year basis and
must file federal information returns in a manner similar to a partnership for
federal income tax purposes. Certain information on such returns will be
furnished to each Residual Certificateholder. The Trust Fund also will be
subject to the procedural and administrative rules of the Code applicable to
partnerships, including rules for determining any adjustments to among other
things, items of REMIC income, gain, loss, deduction or credit by the Service in
a unified administrative proceeding. The holders of Residual Certificates will
generally be entitled to participate in audits of the Trust Fund by the Service
to the same extent as general partners in an audit of a partnership. Regular
Certificateholders will not be entitled to participate in any such audits.
 
    Each Residual Certificateholder is required to treat items on its return
consistently with their treatment on the Trust Fund's return, unless the
Residual Certificateholder either files a statement identifying the
inconsistency or establishes that the inconsistency resulted from incorrect
information received from the Trust Fund. The Service may assert a deficiency
resulting from a failure to comply with the consistency requirement without
instituting an administrative proceeding at the Trust Fund level. The Trust Fund
does not intend to register as a tax shelter pursuant to Section 6111 of the
Code because it is not anticipated that the Trust Fund will have a net loss for
any of the first five taxable years of its existence. Any person that holds a
Residual Certificate as a nominee for another person will be required to furnish
the Trust Fund, in a manner provided in Treasury Regulations, with the name and
address of such person, and other information.
 
    Each Residual Certificateholder, by purchasing its Residual Certificate, (A)
shall be deemed to consent to the appointment of the Servicer as (i) the "tax
matters person" (within the meaning of Section 1.860F-4(d) of the REMIC
Regulations) for the Trust Fund and (ii) attorney-in-fact and agent for any
person that is the tax matters person if the Servicer is unable to serve as the
tax matters person, and (B) agrees to execute any documents required to give
effect to (A) above.
 
NON-REMIC CERTIFICATES
 
    The discussion under this heading applies only to a Series of Certificates
with respect to which a REMIC election is not made ("Non-REMIC Certificates").
 
    A.  CHARACTERIZATION OF THE TRUST FUND.  Upon the issuance of any Series of
Certificates with respect to which no REMIC election is made, Orrick, Herrington
& Sutcliffe LLP, special counsel to Bank of America and Bank of America, FSB,
will deliver its opinion generally to the effect that with respect to each such
Series of Certificates, under then existing law and assuming compliance by the
Seller(s), the Servicer and the Trustee of such Series with all of the
provisions of the related Agreement, and agreement or agreements, if any,
providing for a Credit Facility or a Liquidity Facility, together with any
agreement documenting the arrangement through which a Credit Facility or a
Liquidity Facility is held outside the related Trust Fund, the agreement or
agreements with any Underwriter, for federal income tax purposes,
 
                                       66
<PAGE>
the Trust Fund will be classified as a grantor trust and not as a corporation or
an association which is taxable as a corporation. Accordingly, each Non-REMIC
Certificateholder will be treated for federal income tax purposes as the owner
of an undivided interest in the Contracts and other assets included in the Trust
Fund. As further described below, each holder of a Non-REMIC Certificate must
therefore report on its federal income tax return the gross income from the
portion of the Contracts that is allocable to such Non-REMIC Certificate and may
deduct its share of the expenses paid by the Trust Fund that are allocable to
such Non- REMIC Certificate, at the same time and to the same extent as such
items would be reported by such holder if it had purchased and held directly
such interest in the Contracts and received directly its share of the payments
on the Contracts and paid directly its share of the expenses paid by the Trust
Fund when those amounts are received and paid by the Trust Fund. A Non-REMIC
Certificateholder who is an individual will be allowed deductions for such
expenses only to the extent that the sum of those expenses and certain other of
the Non-REMIC Certificateholder's miscellaneous itemized deductions exceeds 2%
of such individual's adjusted gross income. In addition, the amount of itemized
deductions otherwise allowable for the taxable year of an individual whose
adjusted gross income exceeds certain thresholds will be reduced. Other
potential limitations on deductibility are described above in "REMIC
Certificates-- C. Taxation of Regular Certificates--8. Pass-Through of Expenses
Other Than Interest." Although not clear, it appears that expenses paid by the
Trust Fund, and the gross income used to pay such expenses, should be allocated
among the classes of Non-REMIC Certificates in proportion to their respective
fair market values at issuance.
 
    Under current Service interpretations of applicable Treasury Regulations,
Bank of America or Bank of America, FSB would be able to sell or otherwise
dispose of any subordinated Non-REMIC Certificates. Accordingly, Bank of America
and Bank of America, FSB expect to offer subordinated Non-REMIC Certificates for
sale to investors. In general, such subordination should not affect the federal
income tax treatment of either the subordinated or senior Certificates, and
holders of subordinated classes of Certificates should be able to recognize any
losses allocated to such class when and if losses are realized.
 
    To the extent that any of the Contracts comprising a Contract Pool were
originated on or after March 21, 1984 and under circumstances giving rise to
original issue discount, Certificateholders will be required to report annually
an amount of additional interest income attributable to such discount in such
Contracts prior to receipt of cash related to such discount. See the discussion
above under "REMIC Certificates--C. Taxation of Regular Certificates--2.
Original Issue Discount." Similarly, Code provisions concerning market discount
and amortizable premium will apply to the Contracts comprising a Contract Pool
to the extent that the loans were originated after July 18, 1984 and September
27, 1985, respectively. See the discussions above under "REMIC Certificates--C.
Taxation of Regular Certificates--4. Market Discount" and "REMIC
Certificates--C. Taxation of Regular Certificates--5. Premium."
 
    B.  TAX STATUS OF NON-REMIC CERTIFICATES.  In general, the Non-REMIC
Certificates, other than "Premium Non-REMIC Certificates" (as defined below)
will be (i) "real estate assets" within the meaning of Section 856(c)(5)(A) of
the Code and (ii) assets described in Section 7701(a)(19)(C) of the Code to the
extent the Trust Fund's assets qualify under those Sections of the Code. Any
amount includable in gross income with respect to the Non-REMIC Certificates
will be treated as "interest on obligations secured by mortgages on real
property or on interests in real property" within the meaning of Section
856(c)(3)(B) of the Code to the extent the income on the Trust Fund's assets
qualifies under that Code Section. The Service has ruled that obligations
secured by permanently installed mobile home units qualify as "real estate
assets" under Section 856(c)(5)(A) of the Code. Assets described in Section
7701(a)(19)(C) of the Code include loans secured by mobile homes not used on a
transient basis. However, whether Manufactured Homes would be viewed as
permanently installed for purposes of Section 856 of the Code would depend on
the facts and circumstances of each case. In this regard, investors should note
that, unless stated otherwise in the related Prospectus Supplement, most of the
Contracts in the related Contract Pool prohibit the Obligor from permanently
attaching the related Manufactured Home to its site if it were not so attached
on the date of the Contract. Non-REMIC Certificates that represent the right
solely to interest
 
                                       67
<PAGE>
payments on the Contracts and Non-REMIC Certificates that are issued at prices
that substantially exceed the portion of the principal amount of the Contracts
allocable to such Non-REMIC Certificates (both types of Non-REMIC Certificates,
"Premium Non-REMIC Certificates") should qualify under the foregoing sections of
the Code to the same extent as other Certificates, but the matter is not free
from doubt. Prospective purchasers of Certificates who may be affected by the
foregoing Code provisions should consult their tax advisors regarding the status
of the Certificates under such provisions.
 
    C.  TAXATION OF NON-REMIC CERTIFICATES UNDER STRIPPED BOND RULES.  Certain
classes of Non-REMIC Certificates may be subject to the stripped bond rules of
Section 1286 of the Code. In general, a Non-REMIC Certificate will be subject to
the stripped bond rules where there has been a separation of ownership of the
right to receive some or all of the principal payments on a Contract from
ownership of the right to receive some or all of the related interest payments.
Non-REMIC Certificates will constitute stripped certificates and will be subject
to these rules under various circumstances, including the following: (i) if any
servicing compensation is deemed to exceed a reasonable amount; (ii) if Bank of
America or Bank of America, FSB or any other party retains a retained yield with
respect to the Contracts comprising a Contract pool; (iii) if two or more
classes of Non-REMIC Certificates are issued representing the right to non-pro
rata percentages of the interest or principal payments on the Contracts; or (iv)
if Non-REMIC Certificates are issued which represent the right to interest only
payments or principal only payments. Unless the Prospectus Supplement indicates
otherwise, the Non-REMIC Certificates will be subject to the "stripped bond"
rules of Section 1286 of the Code (or, if the application of those rules to a
particular Series of Non-REMIC Certificates is uncertain, the Trust Fund will
take the position that they apply). There is some uncertainty as to how that
section will be applied to securities such as the Non-REMIC Certificates.
Investors should consult their own tax advisors regarding the treatment of the
Non-REMIC Certificates under the stripped bond rules.
 
    Although the matter is not entirely clear and alternative characterizations
could be imposed, it appears that each stripped Non-REMIC Certificate should be
considered to be a single debt instrument issued on the day it is purchased for
purposes of calculating original issue discount. Thus, in each month the holder
of a Non-REMIC Certificate (whether a cash or accrual method taxpayer) will be
required to report interest income from the Non-REMIC Certificate equal to the
income that accrues on the Non-REMIC Certificate in such month, calculated, in
accordance with the rules of the Code relating to original issue discount, under
a constant yield method. In general, the amount of such income reported in any
month would equal the product of such holder's adjusted basis in such Non-REMIC
Certificate at the beginning of such month (see "--D. Sales of Certificates"
below) and the yield of such Non-REMIC Certificate to such holder. Such yield
would be the monthly rate (assuming monthly compounding) determined as of the
date of purchase that, if used in discounting the remaining payments on the
portion of the Contracts that is allocable to such Non-REMIC Certificate, would
cause the present value of those payments to equal the price at which the holder
purchased the Non-REMIC Certificate.
 
    With respect to certain categories of debt instruments, the Code requires
the use of a reasonable prepayment assumption in accruing original issue
discount and provides a method of adjusting those accruals to account for
differences between the assumed prepayment rate and the actual rate. These rules
apply to "regular interests" in a REMIC and are described under "REMIC
Certificates--C. Taxation of Regular Certificates--2. Original Issue Discount."
Regulations could be adopted applying these rules to the Non-REMIC Certificates.
Although the matter is not free from doubt, it appears that the Taxpayer Relief
Act of 1997 has expanded the requirement of the use of a reasonable prepayment
assumption to instruments such as the Non-REMIC Certificates. In the absence of
regulations interpreting the application of this requirement to such instruments
particularly where such instruments are subject to the Stripped Bond Rules, it
is uncertain whether the assumed prepayment rate would be determined based on
conditions at the time of the first sale of the Non-REMIC Certificates or, with
respect to any holder, at the time of purchase of the Non-REMIC Certificate by
that holder. Finally, if these rules were applied to the Non-REMIC Certificates,
and the principles used in calculating the amount of original issue discount
that
 
                                       68
<PAGE>
accrues in any month would produce a negative amount of original issue discount,
it is unclear when such loss would be allowed.
 
    In the case of a Non-REMIC Certificate acquired at a price equal to the
principal amount of the Contracts allocable to such Non-REMIC Certificate, the
use of a reasonable prepayment assumption would not have any significant effect
on the yield used in calculating accruals of interest income. In the case,
however, of a Non-REMIC Certificate acquired at a discount or premium (that is,
at a price less than or greater than such principal amount, respectively), the
use of a reasonable prepayment assumption would increase or decrease such yield,
and thus accelerate or decelerate the reporting of interest income,
respectively.
 
    If the yield used by the holder of a Non-REMIC Certificate in calculating
the amount of interest that accrues in any month is determined based on
scheduled payments on the Contracts (that is, without using a reasonable
prepayment assumption) and such Non-REMIC Certificate was acquired at a discount
or premium, then such holder generally will recognize a net amount of ordinary
income or loss if a Contract prepays in full in an amount equal to the
difference between the portion of the prepaid principal amount of the Contract
that is allocable to the Non-REMIC Certificate and the portion of the adjusted
basis of the Non-REMIC Certificate (see "--D. Sales of Certificates" below) that
is allocable to the Contract. In general, basis would be allocated among the
Contracts in proportion to their respective principal balances determined
immediately before such prepayment. It is not clear whether any other
adjustments would be required or permitted to take account of prepayments of the
Contracts.
 
    Solely for purposes of reporting income on the Non-REMIC Certificates to the
Service and to certain holders, as required under the Code, it is anticipated
that, unless provided otherwise in the related Prospectus Supplement, the yield
of the Non-REMIC Certificates will be calculated based on (i) a representative
initial offering price of the Non-REMIC Certificates to the public and (ii) a
reasonable Assumed Prepayment Rate, which will be the rate used in pricing the
initial offering of the Non-REMIC Certificates. (Such yield may differ
significantly from the yield to any particular holder that would be used in
calculating the interest income of such holder.) No representation is made that
the Contracts will in fact prepay at the Assumed Prepayment Rate or at any other
rate.
 
    D.  SALES OF CERTIFICATES.  Upon the sale or exchange of a Non-REMIC
Certificate, a Non-REMIC Certificateholder will recognize gain or loss equal to
the difference between the amount realized in the sale and its aggregate
adjusted basis in the Contracts represented by the Non-REMIC Certificate.
Generally, the aggregate adjusted basis will equal the Non-REMIC
Certificateholder's cost for the Non-REMIC Certificate increased by the amount
of any previously reported gain with respect to the Non-REMIC Certificate and
decreased by the amount of any losses previously reported with respect to the
Non-REMIC Certificate and the amount of any distributions received thereon.
Except as provided above with respect to the original issue discount and market
discount rules, any such gain or loss would be capital gain or loss if the
Non-REMIC Certificate was held as a capital asset.
 
    E.  FOREIGN INVESTORS.  Generally, interest or original issue discount paid
to or accruing for the benefit of a Non-REMIC Certificateholder who is a Foreign
Holder (as defined above in "REMIC Certificates--C. Taxation of Regular
Certificates--9. Taxation of Certain Foreign Investors") will be treated as
"portfolio interest" and therefore will be exempt from the 30% withholding tax.
Such Non-REMIC Certificateholder will be entitled to receive interest payments
and original issue discount on the Non-REMIC Certificates free of United States
federal income tax, but only to the extent the Contracts were originated after
July 18, 1984 and provided that such Non-REMIC Certificateholder periodically
provides the Trustee (or other person who would otherwise be required to
withhold tax) with a statement certifying under penalty of perjury that such
Non-REMIC Certificateholder is not a United States person and providing the name
and address of such Non-REMIC Certificateholder. For additional information
concerning interest or original issue discount paid to a Foreign Holder and the
treatment of a sale or exchange of a Non-REMIC Certificate by a Foreign Holder,
which will generally have the same tax
 
                                       69
<PAGE>
consequences as the sale of a Regular Certificate, see the discussion above
under "REMIC Certificates-- C. Taxation of Regular Certificates--9. Taxation of
Certain Foreign Investors."
 
                             OTHER TAX CONSEQUENCES
 
    No advice has been received as to local income, franchise, personal
property, or other taxation in any state or locality, or as to the tax effect of
ownership of Certificates in any state or locality. Certificateholders are
advised to consult their own tax advisors with respect to any state or local
income, franchise, personal property, or other tax consequences arising out of
their ownership of Certificates.
 
            RESTRICTIONS ON TRANSFER OF REMIC RESIDUAL CERTIFICATES
 
    As discussed in "Certain Federal Income Tax Consequences--D. Taxation of
Residual Certificates-- 9. Tax on Transfers of Residual Certificates to Certain
Organizations," in order for the Trust Fund to qualify as a REMIC, there must be
reasonable arrangements designed to ensure that the Residual Certificates are
not held by disqualified organizations. Further, transfers to persons that are
not United States persons raise special tax issues. Accordingly, unless the
related Prospectus Supplement provides otherwise, no record or beneficial
ownership interest in a Residual Certificate that is sold under this Prospectus
may be transferred unless, among other things, the Trustee receives (i) an
affidavit from the proposed transferee to the effect that it is not a
"disqualified organization" and is not purchasing on behalf of a disqualified
organization (see "Certain Federal Income Tax Consequences--D. Taxation of
Residual Certificates--9. Tax on Transfers of Residual Certificates to Certain
Organizations"), (ii) a representation from the proposed transferee to the
effect that it is a citizen or resident of the United States, a corporation,
partnership or other entity created or organized in or under the laws of the
United States or any political subdivision thereof, or an estate or trust whose
income from sources without the United States is includable in gross income for
United States federal income tax purposes regardless of its connection with the
conduct of a trade or business within the United States and (iii) a covenant of
the proposed transferee to the effect that the proposed transferee agrees to be
bound by and to abide by the transfer restrictions applicable to such REMIC
Residual Certificate.
 
                              TAX-EXEMPT INVESTORS
 
    A qualified pension plan or other entity that is exempt from federal income
taxation pursuant to Section 501 of the Code (a "Tax-Exempt Investor")
nonetheless will be subject to federal income taxation to the extent that its
income is "unrelated business taxable income" ("UBTI") within the meaning of
Section 512 of the Code. All "excess inclusions" of a "REMIC" allocated to a
"Residual Certificate" held by a Tax-Exempt investor will be considered UBTI and
thus will be subject to federal income tax. See "Certain Federal Income Tax
Consequences--Certificates as REMIC Residual Interests--7. Excess Inclusions."
 
                                LEGAL INVESTMENT
 
    The Prospectus Supplement for each Series of Certificates will specify
which, if any, of the Classes of Certificates offered thereby constitute
"mortgage related securities" for purposes of the Secondary Mortgage Market
Enhancement Act of 1984 ("SMMEA"). Classes of Certificates that qualify as
"mortgage related securities" will be legal investments for persons, trusts,
corporations, partnerships, associations, business trusts and business entities
(including depository institutions, life insurance companies and pension funds)
created pursuant to or existing under the laws of the United States or of any
state (including the District of Columbia and Puerto Rico) whose authorized
investments are subject to state regulation to the same extent as, under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United States or any such entities. Under SMMEA, if a state enacted
legislation prior to October 4, 1991 specifically limiting the legal investment
authority of any such entities with respect to "mortgage related securities,"
Certificates will constitute legal investments for entities subject to such
 
                                       70
<PAGE>
legislation only to the extent provided therein. Approximately twenty-one states
adopted such legislation prior to the October 4, 1991 deadline.
 
    SMMEA also amended the legal investment authority of federally chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal in Certificates
without limitations as to the percentage of their assets represented thereby,
federal credit unions may invest in mortgage related securities, and national
banks may purchase Certificates for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
Section 24 (Seventh), subject in each case to such regulations as the applicable
federal authority may prescribe. In this connection, federal credit unions
should review the National Credit Union Administration ("NCUA") Letter to Credit
Unions No. 96, as modified by Letter to Credit Unions No. 108, which includes
guidelines to assist federal credit unions in making investment decisions for
mortgage related securities, and the NCUAs regulation "Investment and Deposit
Activities" (12 C.F.R. Part 703), which sets forth certain restrictions on
investment by federal credit unions in mortgage related securities.
 
    All depository institutions considering an investment in the Certificates
(whether or not the Class of Certificates under consideration for purchase
constitutes a "mortgage related security") should review the Federal Financial
Institutions Examination Council's Supervisory Policy Statement on the
Securities Activities (to the extent adopted by their respective regulators)
(the "Policy Statement"), setting forth, in relevant part, certain securities
trading and sales practices deemed unsuitable for an institution's investment
portfolio, and guidelines for (and restrictions on) investing in mortgage
derivative products, including "mortgage related securities," which are
"high-risk mortgage securities" as defined in the Policy Statement. According to
the Policy Statement, such "high-risk mortgage securities" include securities
such as certificates not entitled to distributions allocated to principal or
interest, or subordinated certificates. Under the Policy Statement, it is the
responsibility of each depository institution to determine, prior to purchase
(and at stated intervals thereafter), whether a particular mortgage derivative
product is a "high-risk mortgage security," and whether the purchase (or
retention) of such a product would be consistent with the Policy Statement.
 
    The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders, guidelines or agreements generally
governing investments made by a particular investor, including, but not limited
to "prudent investor" provisions, percentage-of-assets limits and provisions
which may restrict or prohibit investment in securities which are not "interest
bearing" or "income paying."
 
    There may be other restrictions on the ability of certain investors,
including depository institutions, either to purchase Certificates or to
purchase Certificates representing more than a specified percentage of the
investor's assets. Investors should consult their own legal advisors in
determining whether and to what extent the Certificates constitute legal
investments for such investors.
 
                              ERISA CONSIDERATIONS
 
    The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
imposes certain restrictions on employee benefit or other plans subject to ERISA
and/or Section 4975 of the Code ("Plans") and on persons having certain
specified relationships to a Plan ("Parties in Interest") with respect to such
Plans, including, for this purpose, individual retirement arrangements described
in Section 408 of the Code. Certain employee benefit plans, such as governmental
plans and church plans (if no election has been made under Section 410(d) of the
Code), are not subject to the requirements of ERISA, and assets of such plans
may be invested in Certificates without regard to the ERISA considerations
described below, subject to the provisions of other applicable federal and state
law. Any such plan which is qualified under Section 401(a) of the Code and
exempt from taxation under Section 501(a) of the Code is, however, subject to
the prohibited transaction rules set forth in Section 503 of the Code.
 
    Investments by Plans are subject to ERISA's general fiduciary requirements,
including the requirement of investment prudence and diversification and the
requirement that a Plan's investments be made in
 
                                       71
<PAGE>
accordance with the documents governing the Plan. A fiduciary which decides to
invest the assets of a Plan in Certificates should consider, among other
factors, the sensitivity of the investments to the rate of principal payments
(including prepayments) on the Contracts as discussed in "Prepayment and Yield
Considerations" herein.
 
    The United States Department of Labor (the "DOL") has issued regulations
concerning the definition of what constitutes the assets of a Plan (DOL Reg.
Section 2510.3-101). Under the DOL regulations, the underlying assets and
properties of corporations, partnerships and certain other entities in which a
Plan makes an "equity" investment could be deemed for purposes of ERISA to be
assets of the investing Plan in certain circumstances. A beneficial interest in
a trust is defined as an "equity" interest under the DOL regulations. However,
the DOL regulations provide that, generally, the assets of an entity in which a
Plan makes an equity investment will not be deemed for purposes of ERISA to be
assets of such Plan if the equity interest acquired by the investing Plan is a
publicly offered security. A publicly offered security, as defined in DOL Reg.
Section 2510.3-101 is a security that is widely held, freely transferable and
either registered under the Exchange Act or sold to the Plan as part of a public
offering under the Securities Act that then becomes so registered. There can be
no assurance that any Class of Certificate will qualify for this or any other
exception under the DOL regulations.
 
    In addition to the imposition of general fiduciary standards of investment
prudence and diversification, ERISA prohibits a broad range of transactions
involving Plan assets and Parties in Interest, and imposes additional
prohibitions where Parties in Interest are fiduciaries with respect to such
Plan. To the extent that the Contracts may be deemed Plan assets of each Plan
that purchases Certificates, an investment in the Certificates by a Plan could
result in a prohibited transaction under ERISA Sections 406 and 407 and be
subject to an excise tax under Section 4975 of the Code unless a statutory or
administrative exemption applies.
 
    In Prohibited Transaction Class Exemption ("PTCE") 83-1, which amended PTCE
81-7, the DOL exempted from ERISA's prohibited transaction rules certain
transactions relating to the operation of residential mortgage pool investment
trusts and the purchase, sale and holding of "mortgage pool pass-through
certificates" in the initial issuance of such certificates. However, PTCE 83-1
does not apply to trusts that hold Contracts.
 
    Each Plan fiduciary who is responsible for making the investment decisions
whether to purchase or commit to purchase and to hold Certificates must make its
own determination as to the availability of any prohibited transaction
exemptions under ERISA. Each Plan fiduciary should also determine whether, under
the general fiduciary standards of investment prudence and diversification, an
investment in the 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.
 
    Several underwriters of asset-backed securities have applied for and
obtained ERISA prohibited transaction exemptions which are in some respects
broader than PTCE 83-1 and the exceptions to the DOL regulations referred to
above. Such exemptions can only apply to asset-backed securities which, among
other conditions, are sold in an offering with respect to which such an
underwriter serves as the sole or a managing underwriter, or as a selling or
placement agent. If such an exemption might be applicable to a Series of
Certificates, the related Prospectus Supplement will refer to such possibility.
 
    Any Plan fiduciary that proposes to cause a Plan to purchase Certificates
should consult with its counsel concerning the impact of ERISA and the Code, the
applicability of any exemption under ERISA and the potential consequences in its
specific circumstances, prior to making such investment. Moreover, each Plan
fiduciary should determine whether, under the general fiduciary standards of
investment prudence and diversification, an investment in the 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.

                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS
 
GENERAL
 
    The following discussion contains summaries of certain legal aspects of
manufactured housing contracts, including Land-and-Home Contracts, which are
general in nature. Because such legal aspects are governed by applicable state
law (which laws may differ substantially), the summaries do not purport to be
complete nor to reflect the laws of any particular state, nor to encompass the
laws of all states in which the security for the Contracts or Land-and-Home
Contracts is situated. The summaries are qualified in their entirety by
reference to the applicable federal and state laws governing the Contracts or
Land-and-Home Contracts.
 
    As a result of the assignment of Contracts in a Contract Pool to the
Trustee, the related Trust Fund will succeed collectively to all of the rights
(including the right to receive payment on such Contracts), and will assume the
obligations of the obligee, under such Contracts. Each Contract evidences both
(a) the obligation of the Obligor to repay the loan evidenced thereby, and (b)
the grant of a security interest in either the Manufactured Home, and, in the
case of a Land Home Contract or Land-in-Lieu Contract, the real estate on which
the related Manufactured Home is located, to secure repayment of such loan.
Certain aspects of both features of the Contracts are described more fully
below.
 
    The following discussion focuses on issues relating generally to Bank of
America's, Bank of America, FSB's or any lender's interest in manufactured
housing contracts. See "Risk Factors--Security Interests of a Trust Fund in the
Manufactured Homes" herein for a discussion of certain issues relating to the
transfer to a Trust Fund of Contracts and the related security interests in the
Manufactured Homes comprising the related Contract Pool.
 
SECURITY INTERESTS OF BANK OF AMERICA, FSB IN THE MANUFACTURED HOMES (OTHER THAN
  LAND HOME AND LAND-IN-LIEU CONTRACTS)
 
    Each Contract generally will be "chattel paper" as defined in the UCC as in
effect in California (where Bank of America, FSB's and Bank of America's chief
executive offices are located and where the chief executive office of SPFSC is
located) and the jurisdiction in which the related Manufactured Home was located
at origination. Under the UCC as in effect in each such jurisdiction, the sale
of chattel paper is treated in a manner similar to perfection of a security
interest in chattel paper. Bank of America, FSB or Bank of America, as the case
may be, will make or cause to be made appropriate filings of UCC-1 financing
statements to give notice of the Trustee's ownership of the Contracts sold by
it. The Trustee's interest in the Contracts could be defeated if a subsequent
purchaser were able to take physical possession of the Contracts without notice
of such assignment. Unless otherwise specified in the applicable Prospectus
Supplement, Bank of America, FSB or Bank of America or both of them, as the case
may be, will be required under the related Agreement to stamp or cause to be
stamped each Contract sold by it to indicate its transfer to the Trustee. To the
extent the Contracts do not constitute "chattel paper" within the meaning of the
UCC as in effect in California and the jurisdictions in which the related
Manufactured Homes were located at origination, these steps may not be
sufficient to protect the Trustee's interest in the Contracts against the claims
of Bank of America, FSB or Bank of America's (or an affiliate's) creditors, a
receiver or conservator of Bank of America, FSB or Bank of America or a
receiver, conservator or trustee in bankruptcy of an affiliate thereof that sold
such Contracts to Bank of America, FSB or Bank of America.
 
    The Manufactured Homes securing the Contracts in a Contract Pool may be
located in all 50 states and the District of Columbia. Security interests in
manufactured homes similar to the ones securing the Contracts ("manufactured
homes") generally may be perfected either by notation of the secured party's
lien on the certificate of title or by delivery of the required documents and
payment of a fee to the state motor vehicle authority, depending on state law.
In some non-title states, perfection pursuant to the provisions of the UCC is
required. Generally, with respect to manufactured housing contracts individually
originated or purchased by Bank of America, FSB, acting through its division,
BankAmerica Housing
 
                                       73
<PAGE>
Services (for itself or as agent for any affiliate of Bank of America, FSB that
purchases any such contracts from Bank of America, FSB) Bank of America, FSB
effects such notation or delivery of the required documents and fees, and
obtains possession of the certificate of title or a lien certificate, as
appropriate, under the laws of the state in which any manufactured home securing
a manufactured housing contract is registered. If Bank of America, FSB fails,
due to clerical errors or otherwise, to effect such notation or delivery, or
files the security interest under the wrong law (for example, under a motor
vehicle title statute rather than under the UCC, in a few states), Bank of
America, FSB (for itself, or as agent of the secured lender) may not have a
first-priority security interest in the manufactured home securing a contract.
As manufactured homes have become larger and often have been attached to their
sites without any apparent intention to move them, courts in many states have
held that manufactured homes, under certain circumstances, may become subject to
real estate title and recording laws. As a result, a security interest in a
manufactured home could be rendered subordinate to the interests of other
parties claiming an interest in the home under applicable state real estate law.
In order to perfect a security interest in a manufactured home under real estate
laws, the holder of the security interest must file either a "fixture filing"
under the provisions of the UCC or a real estate mortgage under the real estate
laws of the state where the home is located. These filings must be made in the
real estate records office of the county where the home is located. Unless
otherwise specified in the related Prospectus Supplement, most of the Contracts
in any Contract Pool will contain provisions prohibiting the Obligor from
permanently attaching the Manufactured Home to its site if it was not so
attached on the date of the Contract. As long as each Manufactured Home was not
so attached on the date of the Contract and the Obligor does not violate this
agreement, a security interest in the Manufactured Home will be governed by the
certificate of title laws or the UCC, and the notation of the security interest
on the certificate of title or the filing of a UCC financing statement will be
effective to maintain the priority of Bank of America, FSB's security interest
in the Manufactured Home. If any such Manufactured Home does become attached
after the date of the related Contract, the related Contract provides that such
attachment constitutes an "event of default" that, if unremedied, gives rise to
certain discrete remedies including acceleration of the unpaid principal balance
of the Contract plus accrued interest and repossession of the Manufactured Home.
Regardless of whether a full recovery is obtained from an Obligor whose
Manufactured Home becomes attached, Bank of America, Bank of America, FSB or
both will represent that, at the date of the initial issuance of Certificates in
any Series, it had obtained a perfected first-priority security interest in each
of the Manufactured Homes securing the related Contracts sold by it. Such
representation, however, will not be based upon an inspection of the site of any
Manufactured Home to determine if the Manufactured Home had become permanently
attached to its site. See "Description of the Certificates--Conveyance of
Contracts" herein. Neither Bank of America nor Bank of America, FSB will be
required to make fixture filings or to file Mortgages with respect to any of the
Manufactured Homes (except in the case of Land Home and Land-in-Lieu Contracts,
as described below). Consequently, if a Manufactured Home is deemed subject to
real estate title or recording laws because the owner attaches it to its site or
otherwise, the Trustee's interest therein may be subordinated to the interests
of others that may claim an interest therein under applicable real estate laws.
 
    In addition, a federal circuit court decision may adversely affect a
Trustee's interest in the Contract Pool related to a Series of Certificates even
if the related Contracts constitute chattel paper. In Octagon Gas Systems, Inc.
v. Rimmer, 995 F.2d 948 (10th Cir. 1993), the court's decision included language
to the effect that accounts sold by an entity which subsequently became bankrupt
remained property of the debtor's bankruptcy estate. Sales of chattel paper,
like sales of accounts, are governed by Article 9 of the UCC. If any affiliate
of Bank of America, Bank of America, FSB or both of them is subject to the
federal bankruptcy code, sells Contracts to Bank of America or Bank of America,
FSB and becomes a debtor under the federal bankruptcy code, and a court were to
follow the reasoning of the Tenth Circuit and apply such reasoning to chattel
paper, Certificateholders for such Series could experience a delay in, or
reduction of, distributions as to the Contracts that constitute chattel paper
and were sold to the related Trust Fund, directly or indirectly, by any of them.
 
                                       74
<PAGE>
    In the absence of fraud, forgery or permanent affixation of a manufactured
home to its site by the manufactured home owner, or administrative error by
state recording officials, the notation of the lien of Bank of America, FSB on
the certificate of title or delivery of the required documents and fees (or if
applicable, perfection under the UCC) will be sufficient to protect Bank of
America, FSB against the rights of subsequent purchasers of a manufactured home
or subsequent lenders who take a security interest in the manufactured home. If
there are any manufactured homes as to which the security interest in favor of
Bank of America, FSB is not perfected, such security interest would be
subordinate to the claims of, among others, subsequent purchasers for value of
and holders of perfected security interests in such manufactured homes.
 
    In the event that the owner of a manufactured home moves it to a state other
than the state in which such manufactured home initially is registered, under
the laws of most states, the perfected security interest in the manufactured
home would continue for four months after such relocation and thereafter until
the owner registers the manufactured home in such state. If the owner were to
relocate a manufactured home to another state and were to re-register the
manufactured home in such state, and if steps are not taken to re-perfect an
existing security interest in such state, the security interest in the
manufactured home would cease to be perfected. A majority of states generally
require surrender of a certificate of title to re-register a manufactured home.
Bank of America, FSB must therefore surrender possession if it holds the
certificate of title to such manufactured home or, in the case of manufactured
homes registered in states which provide for notation of lien, Bank of America,
FSB would receive notice of surrender if its security interest in the
manufactured home is noted on the certificate of title. Accordingly, Bank of
America, FSB would have the opportunity to re-perfect its security interest in
the manufactured home in the state of relocation. In states which do not require
a certificate of title for registration of a manufactured home, re-registration
could defeat the perfection. In the ordinary course of servicing manufactured
housing contracts, Bank of America, FSB, acting through its division,
BankAmerica Housing Services, takes steps to effect such re-perfection upon
receipt of notice of re-registration or information from the obligor as to
relocation. Similarly, when an obligor under a contract sells a manufactured
home, Bank of America, FSB must surrender possession of the certificate of title
or Bank of America, FSB will receive notice as a result of its lien noted
thereon; accordingly, Bank of America, FSB will have an opportunity to require
satisfaction of the related contract before release of the lien. Such
protections generally would not be available in the case of security interests
in manufactured homes located in non-title states where perfection of such
security interest is achieved by appropriate filings under the UCC (as in effect
in such state). Consequently, the security interest in the manufactured home
could cease to be perfected.
 
    Under the laws of most states, liens for repairs performed on a manufactured
home and liens for personal property taxes take priority over a perfected
security interest in the manufactured home. Each of Bank of America and Bank of
America, FSB will warrant in the Agreement with respect to each Series of
Certificates that, as of the date of initial issuance of such Series of
Certificates, no Manufactured Home relating to a Contract it sold was, to its
knowledge, subject to any such lien. However, such warranty will not be based on
any lien searches or other review. See "Description of the
Certificates--Conveyance of Contracts" in the Prospectus Supplement related to a
Series of Certificates for a description of the remedies for a breach of the
representations and warranties made by Bank of America and Bank of America, FSB
under the related Agreement. In addition, such liens could arise after the date
of initial issuance of the Certificates. Notice may not be given to Bank of
America, Bank of America, FSB, the Servicer, the Trustee or Certificateholders
in the event such a lien arises.
 
ENFORCEMENT OF SECURITY INTERESTS IN MANUFACTURED HOMES
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Servicer on behalf of the Trustee, to the extent required by the related
Agreement, may take action to enforce the Trustee's security interest with
respect to Contracts in default by repossession and resale of the Manufactured
Homes securing such defaulted Contracts. In general, as long as a manufactured
home has not become subject to
 
                                       75
<PAGE>
the real estate law, a creditor can repossess a manufactured home by voluntary
surrender, by "self-help" repossession that is "peaceful" (i.e., without breach
of the peace) or, in the absence of voluntary surrender and the ability to
repossess without breach of the peace, by judicial process. The holder of a
manufactured housing contract generally must give the obligor a number of days'
notice prior to commencement of any repossession. The UCC and consumer
protection laws in most states place restrictions on repossession sales,
including requiring prior notice to the obligor and commercial reasonableness in
effecting such a sale. The law in most states also requires that the obligor be
given notice of any sales prior to resale of the unit so that the obligor may
redeem at or before such resale.
 
    Under the laws applicable in most states, a creditor is entitled to obtain a
deficiency judgment from an obligor for any deficiency on repossession and
resale of the manufactured home securing such obligor's contract. However, some
states impose prohibitions or limitations on deficiency judgments, and in many
cases the defaulting obligor would have no assets with which to pay a judgment.
 
    Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws, and general equitable principles may limit or delay Bank of
America, FSB's ability to repossess and resell any Manufactured Home or enforce
a deficiency judgment.
 
LAND HOME AND LAND-IN-LIEU CONTRACTS
 
    GENERAL.  To the extent described in the applicable Prospectus Supplement,
the related Contract Pool may contain Land Home Contracts or Land-in-Lieu
Contracts. The Land Home Contracts and the Land-in-Lieu Contracts will be
secured by either first mortgages or deeds of trust, depending upon the
prevailing practice in the state in which the underlying property is located. A
mortgage creates a lien upon the real property described in the mortgage. There
are two parties to a mortgage: the mortgagor, who is the borrower, and the
mortgagee, who is the lender. In a mortgage state, the mortgagor delivers to the
mortgagee a note or bond evidencing the loan and the mortgage. Although a deed
of trust is similar to a mortgage, a deed of trust has three parties: the
borrower, a lender as beneficiary, and a third-party grantee called the trustee.
Under a deed of trust, the borrower grants the property, irrevocably until the
debt is paid, in trust, generally with a power of sale, to the trustee to secure
payment of the loan. The trustee's authority under a deed of trust and the
mortgagee's authority under a mortgage are governed by the express provisions of
the deed of trust or mortgage, applicable law, and, in some cases, with respect
to the deed of trust, the directions of the beneficiary.
 
    FORECLOSURE.  Foreclosure of a mortgage is generally accomplished by
judicial action. Generally, the action is initiated by the service of legal
pleadings upon all parties having an interest of record in the real property.
Delays in completion of the foreclosure occasionally may result from
difficulties in locating necessary parties defendants. When the mortgagee's
right to foreclosure is contested, the legal proceedings necessary to resolve
the issue can be time-consuming and expensive. After the completion of a
judicial foreclosure proceeding, the court may issue a judgment of foreclosure
and appoint a receiver or other officer to conduct the sale of the property. In
some states, mortgages may also be foreclosed by advertisement, pursuant to a
power of sale provided in the mortgage. Foreclosure of a mortgage by
advertisement is essentially similar to foreclosure of a deed of trust by
non-judicial power of sale.
 
    Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale under a specific provision in the deed of trust that authorizes
the trustee to sell property to a third party upon any default by the borrower
under the terms of the note or deed of trust. In certain states, such
foreclosure also may be accomplished by judicial action in the manner provided
for foreclosure of mortgages. In some states the trustee must record a notice of
default and send a copy to the borrower-trustor and to any person who has
recorded a request for a copy of a notice of default and the notice of sale. In
addition, the trustee must provide notice in some states to any other individual
having an interest of record in the real property, including any junior
lienholders. If the deed of trust is not reinstated within any applicable cure
period, a notice of sale must be posted in a public place and, in most states,
published for a specified
 
                                       76
<PAGE>
period of time in one or more newspapers. In addition, some state laws require
that a copy of the notice of sale be posted on the property and sent to all
parties having an interest of record in the property.
 
    In some states, the borrower-trustor has the right to reinstate the loan at
any time following default until shortly before the trustee's sale. In general,
the borrower, or any other person having a junior encumbrance on the real
estate, may, during a reinstatement period, cure the default by paying the
entire amount in arrears plus the costs and expenses incurred in enforcing the
obligation. Certain state laws control the amount of foreclosure expenses and
costs, including attorneys' fees, that may be recovered by a lender.
 
    In the case of foreclosure under either a mortgage or a deed of trust, the
sale by the receiver or other designated officer, or by the trustee, is a public
sale. However, because of the difficulty a potential buyer at the sale would
have in determining the exact status of title and because the physical condition
of the property may have deteriorated during the foreclosure proceedings, it is
not common for a third party to purchase the property at the foreclosure sale.
Rather, the lender generally purchases the property from the trustee or receiver
for an amount equal to the unpaid principal amount of the note, accrued and
unpaid interest and the expenses of foreclosure. Thereafter, subject to the
right of the borrower in some states to remain in possession during the
redemption period, the lender will assume the burdens of ownership, including
obtaining hazard insurance and making such repairs at its own expense as are
necessary to render the property suitable for sale. The lender commonly will
obtain the services of a real estate broker and pay the broker a commission in
connection with the sale of the property. Depending upon market conditions, the
ultimate proceeds of the sale of the property may not equal the lender's
investment in the property.
 
    Because of certain requirements of the REMIC Provisions, a Trust Fund as to
which a REMIC election has been made generally must dispose of any related
Manufactured Homes acquired pursuant to repossession, foreclosure, or similar
proceedings within three years after acquisition. Consequently, if the Company
or the Servicing Entity, as applicable, as Master Servicer, or the Servicer, as
the case may be, acting on behalf of the Trust is unable to sell a Manufactured
Home in the course of its ordinary commercial practices within 33 months after
its acquisition thereof (or a longer period as permitted by the Agreement), the
Company or the Servicing Entity, as applicable, as Master Servicer, or the
Servicer, as the case may be, will auction such home to the highest bidder
(which bidder may be the Company or the Servicing Entity, as applicable, as
Master Servicer, or the Servicer, as the case may be) in an auction reasonably
designed to produce a fair price. There can be no assurance that the price for
any Manufactured Home would not be substantially lower than the unpaid principal
balance of the Contract relating thereto. In fact, manufactured homes, unlike
site-built homes, generally depreciate in value, and it has been industry
experience that, upon repossession and resale, the amount recoverable on a
manufactured home securing an installment sales contract is generally lower than
the principal balance of the contract.
 
    RIGHTS OF REDEMPTION.  In some states, after sale pursuant to a deed of
trust or foreclosure of a mortgage, the borrower and certain foreclosed junior
lienors or other parties are given a statutory period in which to redeem the
property from the foreclosure sale. In certain other states, this right of
redemption applies only to sale following judicial foreclosure, and not sale
pursuant to a non-judicial power of sale. In most states where the right of
redemption is available, statutory redemption may occur upon payment of the
foreclosure purchase price, accrued interest and taxes. In some states the right
to redeem is an equitable right. The effect of a right of redemption is to
diminish the ability of the lender to sell the foreclosed property. The exercise
of a right of redemption would defeat the title of any purchaser at a
foreclosure sale, or of any purchaser from the lender subsequent to judicial
foreclosure or sale under a deed of trust. Consequently, the practical effect of
the redemption right is to force the lender to maintain the property and pay the
expense of ownership until the expiration of the redemption period.
 
    ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS.  Certain
states have imposed statutory restrictions that limit the remedies of a
beneficiary under a deed of trust or a mortgagee under a mortgage relating to a
single family residence. In some states, statutes limit the right of the
beneficiary or mortgagee
 
                                       77
<PAGE>
to obtain a deficiency judgment against the borrower following foreclosure or
sale under a deed of trust. A deficiency judgment is a personal judgment against
the borrower equal in most cases to the difference between the amount due to the
lender and the net amount realized upon the foreclosure sale.
 
    Some state statutes may require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an attempt
to satisfy the full debt before bringing a personal action against the borrower.
In certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting such security;
however, in some of these states, the lender, following judgment on such
personal action, may be deemed to have elected a remedy and may be precluded
from exercising remedies with respect to the security. Consequently, the
practical effect of the election requirement, when applicable, is that lenders
will usually proceed first against the security rather than bringing a personal
action against the borrower.
 
    Other statutory provisions may limit any deficiency judgment against the
former borrower following a foreclosure sale to the excess of the outstanding
debt over the fair market value of the property at the time of such sale. The
purpose of these statutes is to prevent a beneficiary or a mortgagee from
obtaining a large deficiency judgment against the former borrower as a result of
low or no bids at the foreclosure sale.
 
    In some states, exceptions to the anti-deficiency statutes are provided for
in certain instances where the value of the lender's security has been impaired
by acts or omissions of the borrower, for example, in the event of waste of the
property.
 
    In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws,
the federal Soldiers' and Sailors' Civil Relief Act of 1940 and state laws
affording relief to debtors, may interfere with or affect the ability of a
secured mortgage lender to realize upon its security and/or enforce a deficiency
judgment. For example, with respect to a Land Home Contract, in a proceeding
under the federal Bankruptcy Code, the court may prevent a lender from
foreclosing on the home, and when a court determines that the value of a home is
less than the principal balance of the loan, the court may reduce the amount of
the secured indebtedness to the value of the home as it exists at the time of
the proceeding, leaving the lender as a general unsecured creditor for the
difference between that value and the amount of outstanding indebtedness. A
bankruptcy court may grant the debtor a reasonable time to cure a payment
default, reduce the monthly payments due under such mortgage loan, change the
rate of interest and/or alter the mortgage loan repayment schedule.
 
    The Code provides priority to certain tax liens over the lien of the
mortgage or deed of trust. The laws of some states provide priority to certain
tax liens over the lien mortgage or deed of trust. Numerous federal and some
state consumer protection laws impose substantive requirements upon mortgage
lenders in connection with the origination, servicing and the enforcement of
mortgage loans. These laws include the federal Truth in Lending Act, Real Estate
Settlement Procedures Act, Equal Credit Opportunity, Fair Credit Billing Act,
Fair Credit Reporting Act, and related statutes and regulations. These federal
laws and state laws impose specific statutory liabilities upon lenders who
originate or service mortgage loans and who fail to comply with the provisions
of the law. In some cases, this liability may affect assignees of the Contracts.
 
CONSUMER PROTECTION LAWS
 
    The so-called "Holder-in-Due-Course" rule of the Federal Trade Commission is
intended to defeat the ability of the transferor of a consumer credit contract
which is the seller of goods which gave rise to the transaction (and certain
related lenders and assignees) to transfer such contract free of notice of
claims by the obligor thereunder. The effect of this rule is to subject the
assignee of such a contract to all claims and defenses which the obligor could
assert against the seller of goods. Liability under this rule is limited to
amounts paid under such a contract; however, the obligor also may be able to
assert the rule to set off remaining amounts due as a defense against a claim
brought by the assignee against such obligor. Generally, this rule will apply to
any Contracts conveyed to the Trustee and to any claims made by the
 
                                       78
<PAGE>
Servicer on behalf of the Trustee, as Bank of America's or Bank of America,
FSB's assignee, as applicable. Numerous other federal and state consumer
protection laws impose requirements applicable to the origination and lending
pursuant to such Contracts, including the Truth in Lending Act, the Federal
Trade Commission Act, the Fair Credit Billing Act, the Fair Credit Reporting
Act, the Equal Credit Opportunity Act, the Fair Debt Collection Practices Act
and the Uniform Consumer Credit Code. In the case of some of these laws, the
failure to comply with their provisions may affect the enforceability of the
related Contract or create liability for the Trust Fund.
 
    The Soldiers' and Sailors' Civil Relief Act of 1940, as amended (the "Relief
Act") could, under certain circumstances, cap the amount of interest that may be
charged on certain Contracts at 6% and may hinder the ability of the Servicer to
foreclose on such Contracts in a timely fashion. Under the terms of the Relief
Act, if so required by an obligor under a manufactured housing contract who
enters military service after the origination of such obligor's contract
(including an obligor who is a member of the National Guard or is in reserve
status at the time of the origination of the contract and is later called to
active duty), such obligor may not be charged interest above an annual rate of
6% during the period of such obligor's active duty status, unless a court orders
otherwise upon application of the lender. In addition, the Relief Act imposes
limitations which would impair the ability of any lender to foreclose on an
affected contract during the obligor's period of active duty status and within
three months thereafter. It is possible that application of the Relief Act to
certain of the Contracts could have an effect, for an indeterminate period of
time, on the ability of the Servicer to collect full amounts of interest or
foreclose on such Contract, and could result in delays in payment or losses to
the holders of the Certificates. Neither Bank of America nor Bank of America,
FSB will make any representation or warranty as to whether any Contract is or
could become subject to the Relief Act.
 
TRANSFERS OF MANUFACTURED HOMES; ENFORCEABILITY OF RESTRICTIONS ON TRANSFER
 
    Unless otherwise specified in the related Prospectus Supplement, the
Contracts comprising any Contract Pool generally will prohibit the sale or
transfer of the related Manufactured Homes without the consent of the obligee
and permit the acceleration of the maturity of the Contracts by the obligee upon
any such sale or transfer to which Bank of America, FSB has not consented. Under
the Agreement for a Series of Certificates (unless otherwise specified in the
related Prospectus Supplement), Bank of America, FSB, acting through its
division BankAmerica Housing Services as Servicer, will be required to consent
to any such transfer and to permit the assumption of the related Contract if the
proposed buyer meets the Servicer's underwriting standards and enters into an
assumption agreement, the Servicer determines that permitting such assumption
will not materially increase the risk of nonpayment of the Contract and such
action will not adversely affect or jeopardize any coverage under any insurance
policy required by such Agreement. If the Servicer determines that these
conditions have not been fulfilled, then it will be required to withhold its
consent to the transfer, but only to the extent permitted under the Contract and
applicable law and governmental regulations and only to the extent that such
action will not adversely affect or jeopardize any coverage under any insurance
policy required by the Agreement. In certain cases, a delinquent Obligor may
attempt to transfer a Manufactured Home in order to avoid a repossession
proceeding with respect to such Manufactured Home.
 
    In the case of a transfer of a Manufactured Home after which the obligee
desires to accelerate the maturity of the related Contract, the obligee's
ability to do so will depend on the enforceability under state law of the clause
permitting acceleration on transfer. The Garn-St. Germain Depository
Institutions Act of 1982 preempts, subject to certain exceptions and conditions,
state laws prohibiting enforcement of such clauses applicable to manufactured
homes. To the extent such exceptions and conditions apply in some states, the
Servicer may be prohibited from enforcing such a clause in respect of certain
Manufactured Homes.
 
                                       79
<PAGE>
APPLICABILITY OF USURY LAWS
 
    Title V of the Depository Institutions Deregulation and Monetary Controls
Act of 1980, as amended ("Title V"), provides that, subject to the following
conditions, state usury limitations shall not apply to any loan which is secured
by a first lien on certain kinds of manufactured housing. The Contracts related
to any Series of Certificates would be covered under Title V if, among other
things, they satisfy certain conditions governing the terms of any prepayments,
late charges and deferral fees and contain a requirement of a 30-day notice
period prior to instituting any action leading to repossession of the related
unit.
 
    Title V authorized any state to reimpose limitations on interest rates and
finance charges by adopting before April 1, 1983 a law or constitutional
provision which expressly rejected application of the federal law. Fifteen
states adopted such a law prior to the April 1, 1983 deadline. In addition, even
where Title V was not so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on loans covered by Title V.
Bank of America, FSB or, where applicable, Bank of America will represent, in
the Agreement for a Series of Certificates (unless otherwise specified in the
related Prospectus Supplement), that the Contracts sold by it comply with
applicable usury laws.
 
                                    RATINGS
 
    It is a condition to the issuance of the Certificates of each Series offered
hereby that at the time of issuance they shall have been rated in one of the
four highest rating categories by the nationally recognized statistical rating
agency or agencies specified in the related Prospectus Supplement.
 
    Ratings on manufactured housing contract pass-through certificates address
the likelihood of the receipt by certificateholders of their allocable share of
principal and interest on the underlying manufactured housing contract assets.
These ratings address structural and legal aspects associated with such
certificates, the extent to which the payment stream on such underlying assets
is adequate to make payments required by such certificates and the credit
quality of the credit enhancer or guarantor, if any. Ratings on the Certificates
do not, however, constitute a statement regarding the likelihood of principal
prepayments by Obligors under the Contracts in the related Contract Pool, the
degree by which prepayments made by such Obligors might differ from those
originally anticipated or whether the yield originally anticipated by investors
of any Series of Certificates may be adversely affected as a result of such
prepayments. As a result, investors of any Series of Certificates might suffer a
lower than anticipated yield.
 
    A rating on any or all of the Certificates of any Series by certain other
rating agencies, if assigned at all, may be lower than the rating or ratings
assigned to such Certificates by the rating agency or agencies specified in the
related Prospectus Supplement. A security rating is not a recommendation to buy,
sell or hold securities and may be subject to revision or withdrawal at any time
by the assigning rating agency. Each security rating should be evaluated
independently of any other security rating.
 
                             METHOD OF DISTRIBUTION
 
    The Sellers may sell Certificates of each Series to or through underwriters
(the "Underwriters") by a negotiated firm commitment underwriting and public
reoffering by the Underwriters, and also may sell and place Certificates
directly to other purchasers or through agents. The Sellers intend that
Certificates be offered through such various methods from time to time and that
offerings may be made concurrently through more than one of these methods or
that an offering of a particular Series of Certificates may be made through a
combination of such methods.
 
    This Prospectus and any related Prospectus Supplement may be used by
BancAmerica Robertson Stephens, an affiliate of the Sellers, in connection with
offers and sales related to market making transactions in any Series of the
Certificates. BancAmerica Robertson Stephens may act as principal or agent in
such transactions. Such sales will be made at prices related to prevailing
market prices at the time of the sale.
 
                                       80
<PAGE>
    The distribution of the Certificates may be effected from time to time in
one or more transactions at a fixed price or prices, which may be changed, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
    If so specified in the Prospectus Supplement relating to a Series of
Certificates, the Sellers or any affiliate thereof may purchase some or all of
one or more Classes of Certificates of such Series from the Underwriter or
Underwriters at a price specified in such Prospectus Supplement. Such purchaser
may thereafter from time to time offer and sell, pursuant to this Prospectus,
some or all of such Certificates so purchased directly, through one or more
Underwriters to be designated at the time of the offering of such Certificates
or through broker-dealers acting as agent and/or principal. Such offering may be
restricted in the manner specified in such Prospectus Supplement. Such
transactions may be effected at market prices prevailing at the time of sale, at
negotiated prices or at fixed prices.
 
    In connection with the sale of the Certificates, Underwriters may receive
compensation from the Sellers or from purchasers of Certificates for whom they
may act as agents in the form of discounts, concessions or commissions.
Underwriters may sell the Certificates of a Series to or through dealers and
such dealers may receive compensation in the form of discounts, concessions or
commissions from the Underwriters and/or commissions from the purchasers for
whom they may act as agents. Underwriters, dealers and agents that participate
in the distribution of the Certificates of a Series may be deemed to be
Underwriters, and any discounts or commissions received by them from the Sellers
and any profit on the resale of the Certificates by them may be deemed to be
underwriting discounts and commissions, under the Securities Act. Any such
Underwriters or agents will be identified, and any such compensation received
from the Sellers will be described, in the Prospectus Supplement.
 
    Under agreements which may be entered into by Bank of America, Bank of
America, FSB or both of them, Underwriters and agents who participate in the
distribution of the Certificates may be entitled to indemnification by Bank of
America or Bank of America, FSB, as the case may be, against certain
liabilities, including liabilities under the Securities Act.
 
    The Underwriters may, from time to time, buy and sell Certificates, but
there can be no assurance that an active secondary market will develop and there
is no assurance that any such market, if established, will continue.
 
                                USE OF PROCEEDS
 
    Unless otherwise specified in the applicable Prospectus Supplement,
substantially all of the net proceeds to be received from the sale of the
Certificates will be used by the Sellers for general corporate purposes,
including the payment of expenses in connection with pooling the Contracts and
issuing the Certificates.
 
                                 LEGAL MATTERS
 
    Certain legal matters relating to the Certificates, including legal matters
relating to material federal income tax consequences concerning the
Certificates, will be passed upon for Bank of America and Bank of America, FSB
by Orrick, Herrington & Sutcliffe LLP, San Francisco, California.
 
                              OTHER CONSIDERATIONS
 
    As federally insured depository institutions, Bank of America and Bank of
America, FSB are subject to conservatorship and receivership rules enacted
pursuant to the Financial Institutions Reform, Recovery and Enforcement Act of
1989, as amended ("FIRREA"). If a receiver or conservator were appointed for
Bank of America, FSB, the receiver or conservator could prevent the termination
of Bank of America, FSB as Servicer and the appointment of a successor Servicer
if no event of default under the applicable Agreements exists other than the
receivership, conservatorship or insolvency of the Servicer. In addition,
 
                                       81
<PAGE>
the appointment of a receiver or conservator for Bank of America, FSB could
result in a delay or possibly a reduction in payments on the Certificates to the
extent Bank of America, FSB received (but did not deposit with the Trustee)
Contract collections before the date of receivership or conservatorship.
 
    Each of the Sellers believes that the transfer of Contracts sold by it to
any Trust Fund will constitute absolute and unconditional sales. However, in the
event of a conservatorship or receivership of Bank of America, Bank of America,
FSB or both of them, a conservator or receiver, as the case may be, could
recharacterize the sale of Contracts by Bank of America or Bank of America, FSB,
or both of them, as a borrowing secured by a pledge of the Contracts sold by it.
Such an attempt, even if unsuccessful, could result in delays in or reductions
of distributions on the Certificates offered hereby and by the related
Prospectus Supplement. If such an attempt were successful, the conservator or
receiver, as the case may be, could elect to accelerate payment of the
Certificates and liquidate the Contracts, with the holders of Certificates
entitled to no more than the then outstanding principal amount of such
Certificates together with interest at the applicable Pass-Through Rate to the
date of payment. Thus, the holders of Certificates
could lose the right to future distributions of interest, and might suffer
reinvestment loss in a lower interest rate environment.
 
    The foregoing discussion does not purport to be comprehensive. Prospective
investors should consult their own legal advisors as to the possible
consequences of any insolvency, conservatorship, receivership or similar
proceeding instituted by or in respect of Bank of America or Bank of America,
FSB.
 
    Similar consequences could result from a bankruptcy proceeding instituted by
or in respect of any affiliate of Bank of America or Bank of America, FSB that
sells Contracts to Bank of America or Bank of America, FSB or both and becomes
subject to a bankruptcy, conservatorship, receivership or similar proceeding.
Prospective investors should consult their own legal advisors as to such
matters.
